Explorations of Tessellated forms for Architectural Application Dissertation

Explorations of Tessellated forms for Architectural Application - Dissertation Example Trends in the Australian housing market are discussed, with connections drawn to emerging technologies as a means of expediting architecture and the mechanical process of construction. The principles of tessellation and 3-D printing will be discussed with proposed applications for architectural usage, as well as a discussion on the ramifications for the construction market. Table of Contents Introduction †¦p. 4 Literature Review †¦ p. 7 Conclusion †¦..p. 20 References †¦ p. 22 Introduction Architecture is among the principal forms of cultural expression available to any society, and represents a vital synthesis between technology, aesthetics, and the way in which a society perceives itself. Part of this perception is dependent upon the ability to adapt to modern technological realities and adapting to them accordingly. This investigation includes two new technological dimensions applied to theories of architecture to provide a new predictive element for the future growth of the design and construction principles inherent in architecture. The design principles upon which the urban landscape depends touch every aspect of modern life, from the aesthetics involved in fashion or jewelry, to the functional tools developed for mechanical or surgical work, similar design elements and technological solutions are applied which can inform urban design and architectural theories that shake our living societies. Design, architecture, and art in general form and intersect that will be informed by new advances described during the course of this analysis to create potential for a new dimension of design techniques applicable not only in architecture, but throughout a wide range of disciplines. This study will explore a possible future of architecture made available through the adaptation of two relatively novel scientific concepts: 3-D printing and tessellation. In a broad sense, the theories of tessellation will be explored at length, combined with the ne w potentials inherent in 3-D printing, which will be explored as a functional mechanism. The theoretical principles of tessellation are applicable to the technology of 3-D printing, and this investigation will explore possible developments of this design system for use in architecture. In terms of current trends in Australian architecture, it is necessary to remain cognizant of the aftereffects of the recent global financial crisis, however these international financial issues have affected Australia somewhat less than other countries. Regardless, it is inevitable that an interconnected global economy will still impact every advanced economy. Markets affecting new buildings and home design are nonetheless influenced by international issues, and as a result demand exists for structural flexibility as well as quality (Zenere, 2013). A trend towards increased flexibility underscores the need for a revision of old assumptions, and an adaptation of new technologies to meet the diversity of human needs with a greater range of options than in the past. Renewed interest in a flexibility of options will create a demand for novelty in terms of architectural design options, as old standards are revised to make way for the new economy. In addition to flexibility there is a demand for uniqueness within the reasonable boundaries of domestic comfort. Zenere (2013) describes a modern Australian home market where customers are interested in airy spaces with ample illumination and adaptability in terms of its overall design, in order to accommodate flexible living conditions. The modern economic circumstances prevailing throughout much of the industrialized world creates a social dynamic which

Globalization of the world Essay Cosmetic surgery is one of surgical and medical techniques to improve physical appearances. It is reserving normal appearance, repairing it or enhancing it exceeds the usual physical looks with regard to some aesthetic essence. A shocking data shows that a lot of teenagers, 18-and-unders, had gone under the knife. According to the American Society of Plastic and Reconstructive Surgeons (ASPS), more than 219,000 cosmetic procedures were done on patients aged 18 and younger in 2008 (Mann, 2011). Todays society really concerns about this issue since the age of 18 and under are considered still too young to do procedures. Nowadays, it is very common to have a cosmetic surgery done in order to improve and enhance physical appearances or any other so-called imperfections. People choose to go under the knife as an easy way out. Nips and tucks are apparently increasing everywhere. The top 7 countries with most cosmetic surgery are: South Korea, Greece, Italy, Brazil, Colombia, The USA, and Taiwan (Conley, 2012). In South Korea, 41.1 percent of teens are willing to do plastic surgery for beauty. They have a desire to look better; it even can be an obsession. Many kids at the age of 14 would like to have an â€Å"eye jobs†, a surgery to have bigger eyes, as their graduation gift from their parents (Dubroff, 2011). In the United States of America, those teenagers who are unhappy and not satisfied with their physical looks choose to change them permanently through the risky and dangerous cosmetic surgery (Mann, 2001). In 2009, about 8,000 girls age 13 to 19 had their breasts enlarged last year, accordi ng to the American Society of Plastic Surgeons. And 2,953 of them were age 18 and younger (Thompson, 2010). After going through so many frightening news about teenagers with their obsessions to look good until they choose cosmetic surgery and the dangers that can come along, the society starts questioning, should cosmetic surgery be banned among teenagers, 18-and-under? This question has resulted in dissimilar views on this issue and certainly causes a series of arguments from both sides of the stand. The purpose of this research is to show that cosmetic surgery should indeed be banned among teenagers due to its danger and teenagers are unaware to evaluate risks. Moreover, at young age, teenagers should focus on school and their future. Having cosmetic surgery done for unnecessary reasons is non-essential. This report will clearly point out why cosmetic surgery should be banned among teenagers by providing several evidences to reinforce this belief. 2.0 BODY OF REPORT 2.1 Cosmetic Surgery is Highly Dangerous Going under the knife is very risky and dangerous, but people don’t seem to be aware nor take into consideration about the danger. Psychologists and surgeons are afraid that many patients do not completely understand and know the potential risks of the operations (Sheng, 2012). Cosmetic surgery and its risks and dangers come in one package, so it is prominent for those who are thinking to go under the knife to acknowledge them. The major risk or danger that are associated with cosmetic surgery is that pain and discomfort (Zemanta, 2013). Even though not every cosmetic surgery procedure leads to lack of physical comfort and ache, but many of them do. Although the patients’ ache and discomfort can be treated with pain medicines that they can get without prescription or an ice pack, it may disturb the patients’ daily activities. Moreover, the pain may be really painful that those teenagers cannot bear and end up won’t not be able to come to school to study. The chance that complication may be the result of cosmetic surgery is another danger (Zemanta, 2013). Most patients do not necessarily consider that complications may arise. When anesthesia is given to a patient, there is a possibility that the anesthesia used to put the patient to sleep for the procedure, could give a reaction to the patient (Palmer, 2006). Even though this happens relatively rare, it’s able to be life-threatening and even deadly. One famous case is the death of Kanye West’s Mother. She actually died from the anesthesia (Adato, 2007). Another certain thing that teenagers should know about what can happen if they are undergoing cosmetic surgery is, at the age of 18 and below, the body has not yet matured to its final shape (Mann, 2011). Procedures like breast enlargement, liposuction, and breast reduction are surgeries that should wait until reaching adulthood. Until 18, breasts might not be fully-grown, and saline-filled breast implants (the type typically used for cosmetic enhancements) arent even permitted for under-18s (DiscoveryHealth.com, 2012). Having cosmetic surgery at young age may give them more risks. The scariest risk a patient should take into his/her consideration to have a cosmetic surgery procedure is death. Cosmetic surgery has been proven a killer. One of the famous cases is Stephanie Kuleba’s case. She was a pretty and popular girl who went for a breast augmentation. She died after suffering from the complications (Rivero, 2008). 1 in 1000 cosmetic surgery procedures in the United State of America results in complications, which lead to everlasting injury. Studies show that 7 to 12 percent of cosmetic surgery patients die from the procedure. 20 percent of patients suffer from injection and bleeding (Top 10 Hidden Dangers Of Cosmetic Surgery, n.d.). Hence, teenagers should be aware that cosmetic surgery is not as safe as most people believe it to be. Although the risks and dangers that come together with cosmetic surgery have been known, there are quite a number of people who are confident that cosmetic surgery is becoming safer and safer due to the increasingly strict policies and the improvement in technology (McGilchrist, 2011). They claim that todays regulations and policies for such operation are becoming more strict so it can only be done by professionals thus it is able to minimize the danger. Conversely, this argument is not completely true. The data and survey are shown and it only shows less than 25%, but it is still a big deal. There is always that chance to become a cosmetic surgery death statistic. The American Society of Plastic Surgeons is strongly against the idea of teenagers younger than 18 undergo plastic surgery (Rivero, 2008). From every aspect, regardless to nowadays-cosmetic surgery’s safety that is becoming safer so there will be less risks and dangers, cosmetic surgery among teenagers is still a high-risk and dangerous thing. The evidence in this research obviously shows that there are a lot of teenagers have to suffer the bleeding and other complications that can lead them to the death after undergoing cosmetic surgery. A teenager’s live and future are priceless and worth more than $3,500 cosmetic surgery. 2.2 Teenagers Are Unaware of Evaluating Risks Teen or adolescence is a transitional stage of physical and psychological human development (Merriam-Webster, 2012). It is the stage when a teenager is too mature to be called and treated as a kid yet too young to be called as an adult. Teens are also known to be reckless, moody, impulsive, insecure, rebellious, and argumentative (Pickrell, 2006). They might think they are mature enough to make any decisions for themselves but sadly sometimes teenagers do not think further regarding the consequences of their actions. There is a high peer pressure that boosts them to be unafraid of doing risky things just to fit it and be accepted. Going through having doubts and insecurities about their body image is also a part of growing up that most teenagers experience. The society puts a huge significance on physical attractiveness (Wansbrough, 2013). Peer pressure to look â€Å"normal† and â€Å"good† is the driving force teens are interested in cosmetic surgery (Keyes, 2011). Britanni, a girl who had her breast implants on the age of 18 said â€Å"I didn’t have large breasts when I was younger, and all my friends did†¦I felt very self conscious about it.† (Wallace, 2012). 67% of average 14 years of age girls quizzed said the pressure is from boys and celebrities with perfect bodies (BBC News, 2005). Ms Horton said that the infinite parade of thin yet curvy, surgically-enhanced celebrities has made young girls obsessed with their own normal lumpy, bumpy bodies. More over, boys’ expectations on their girlfriends to look like the perfect celebrity body model are also the pressures (BBC News, 2005). Todays society introduces the miracle-makers as known as cosmetic surgery to teens at a young age as seeing the fact that according to the American Society for Aesthetic Plastic Surgery, there are more than 223,000 cosmetic procedures were performed on patients whose age were between thirteen to eighteen years old for example; breast augmentation, liposuction, breast lifts, tummy tucks, and nose reshaping (Olding Zuckerman, 2004). It is undeniable, teen cosmetic surgery is on the rise. Unfortunately, the idea of having good physical appearance by going under the knife is not coupled by considering and evaluating the risks. Youngsters are not alert to the undeniable lasting health consequences of smoking, drinking alcohol, tanning and other dangerous behaviors, and nor likely to aware of the risks of cosmetic surgery (Keyes, 2011). They only see the magical outcome of cosmetic surgery as seen on celebrities on the cover of glossy magazines with their perfect breast, bottoms, lips, no se, eyes and everything (BBC News, 2005). They likely do not take into account the danger and risks of cosmetic surgery. They would likely to only believe that cosmetic surgery is the only way out to obtain physical perfection as the society ‘demand’. They are unable to evaluate risks as well as an adult. The scientists discovered that the teen’s brain is more sensitive to the rewarding indicators it gets when something better than expected happens. A nerve-signaling molecule that helps the brain in processing rewards and can be involved in addictions is called dopamine. The more dopamine flowing in the brain, the more likely a teenager to feel a risky behavior is more rewarding if it ends well, than it might seem to a child or adult (Discovery, 2013). However, some parties are against this idea. They claim that teenagers have every right to do whatever they want to do with their bodies. They should be able to make their own decision. To some extend, yes this is true. As humans, teenagers have the freedom to do anything as they please, but when it comes to do cosmetic surgery procedures, there are a lot to take into consideration as it will affect their physical looks permanently. The outcomes of cosmetic surgery are also various (BBC News, 2005). It can be just as what they expected but also can be far from their expectations. Cosmetic surgery is a big deal and teenagers are not reliable enough to make the decision. Teenagers are greatly affected by what they see in the media. They undergo unnecessary cosmetic surgeries to achieve the Barbie standard, but sometimes resulting in regret. In 2003, it was estimated that fifteen percent of teenage cosmetic surgeries in the US was due to misinformed decisions (Olding Zuckerman, 2004). Hence, it’s clearly shown from the facts, cosmetic surgery should be banned because many teenagers are unaware of evaluating the risks. Thus, a ban on teenagers of 18 and below should be put into place. 2.3 Teenagers Should Focus On Their Future Teen is the stage where the future is based on because in this stage teenagers are on their pursuit of anything they want to be. Most teenagers have goals to be achieved someday in the future. Achieving those goals and making dreams come true are more important and useful instead of enhancing physical appearances, which only skin deep. The significance of education can be explained very easy. Without education, it is difficult for human beings to survive properly. Through education, one’s potential can be utilized to maximum extent. Education teaches men how to make decision, how to work properly, and how to think. Through education alone can make separate identity. It became a necessity just like foods, clothes, and shelter. It is very usual for teenagers to wonder how their career will be. In the future, most people want to own a car, a house, and have family. Each of these things would not be easy to afford on a minimum wage salary. Many drop-outs have earned minimum wage and live just above the poverty line (Bloom Haskins, 2010). Therefore, through higher education, people will be brought to a bigger career opportunities and a higher payroll. Education is a productive and beneficial aspect in one’s life. The training of a human mind is not complete without education. All these facts clearly shows that there are many other things that are more important to be concerned about instead of enhancing physical appearances. Moreover, plastic surgery, just like drugs, alcohol, and cigarettes, it can be addictive especially if a patient starts at a young age (Pruitt, 2009). According to Tom Horvath, addiction is marked by three fundamental symptoms: repeated involvement in an activity; an act brought on by cravings; and one done despite negative consequences (Rettner, 2010). Most patients who have undergone cosmetic surgery and had a good outcome would most likely to go for another procedures hence it becomes continual. This could probably lead to even more demand for a nip here and a tuck there (Pruitt, 2009). One thing that most teenagers tend to forget these days is beauty is only skin-deep. What’s within them, which is their personality are more important than the physical looks. Beauty cannot be quantified or objectively measured; it is the result of the judgments of others. The concept is difficult to define, as it is equated with different, sometimes contradictory, ideas. When people are asked to define beauty, they tend to mention abstract, personal qualities rather than external, quantifiable ones (Freedman, 1986; Hatfield Sprecher, 1986). Beauty ideals are created and maintained by society’s elite (Saltzberg Chrisler, 1995). This does not mean that physical looks are not important, but this means that it’s not the most important thing and many other things are more important than that. Thus, it is wiser to concern more about the future than the physical looks. Hence, cosmetic surgery should be banned among teenagers. 3.0 RECOMMENDATION Look at how critical this issue at hand is, what the government should do is to establish age limitation to undergo plastic surgery. This plastic surgery refers to the unnecessary one not the reconstructive plastic surgery. Hence, only those who are ready physically and mentally can undergo cosmetic surgery procedures. Moreover, after going through so many researches, the root of teen’s cosmetic surgery has been discovered. It is low self-esteem due to society pressure on physical looks. Thus, creating a platform where teenagers are encouraged to showcase their skills and talents is important. Such skills and talents eventually will be an asset that they are proud of. Instead of being acknowledged by their peers through their looks, they could actually gain the acknowledgment through their achievement. In a nutshell, these achievements will replace the needs to polish their appearance in particular by having cosmetic surgery. Moreover, teenagers also should be educated how scary and dangerous the dangers of cosmetic surgery that’s why it requires a lot of thinking and taking all consequences into account when making decision to go under the knife. 4.0 CONCLUSION As it can clearly be seen, teen cosmetic surgery is highly dangerous and risky as the patient has a great possibility to suffer from bleeding and complications after doing the procedures. This may cause them to lose their lives. Moreover, teenagers are likely unrealistic decision makers because they do not take into account further bad possibilities that may occur from post cosmetic surgery. Nevertheless, as a teenager, one should focus and be putting their concentration on building up their future and achieving long-term goals instead of enhancing their physical appearances. Thus, it is prominent to ban unnecessary cosmetic surgery among teenagers. Although there is a great improvement in technology and teenagers have their rights to do anything they want to do, there are still many possibilities a patient to die from the procedures. So, it is wiser to give the teenagers some kind of protection by banning teen cosmetic surgery. References BBC News. (2005). 40% of teens want plastic surgery.

The Second World War (WWII) - News Article :: World War 2 II Two

The Bomb Was Dropped Today is the day after the mass destruction of Hiroshima. On Monday, August 6th the first atomic bomb to be used in war fare was dropped. The atomic bomb â€Å"Little Boy† as they called it was drooped at approximately 8:15am Japanese standard time. The B-29 Bomber â€Å"Enola Gay† was the one to have dropped the atomic bomb yesterday which caused mass destruction. When the bomb reached approximately 2,000 feet above the surface it was detonated. Reports say that â€Å"Little Boy† caused a massive wind that leveled houses up to 1.5 miles from the center of the explosion. â€Å"A bright light filled the plane," wrote Lt. Col. Paul Tibbets, the pilot of the Enola Gay, the B-29 that dropped the first atomic bomb. "We turned back to look at Hiroshima. The city was hidden by that awful cloud...boiling up, mushrooming." He was astonished at what they have done. Today the day after the drop of â€Å"Little Boy† it is unknown of the amount of deaths and it is believed to be in the tens of thousands. What will happen next? Will we see Japan surrender the war? In the up coming days we will see how this concludes. Today is the day after the mass destruction of Hiroshima.

Module Five: The Sacraments Essay

Trace the development of the celebration of the Sacrament of the Eucharist from the early church with special reference to how it is understood and celebrated in the Church since the Second Vatican Council. Assignment: 3. Trace the development of the celebration of the Sacrament of the Eucharist from the early church with special reference to how it is understood and celebrated in the Church since the Second Vatican Council. We all have experience of ‘celebration’. When I think of a celebration what comes to mind are the external factors, the cake, candles, and the food. Sometimes we forget the real meaning of celebration, the story behind the festivity. The celebration of the sacrament of the Eucharist is where we find our story. This essay will outline the development of the celebration of the Sacrament of the Eucharist from the Early Church, paying particular focus on how the Eucharist is celebrated in the church since the Second Vatican Council. Sacraments in the Roman Catholic Church celebrate something, and that something is to do with God’s love and grace, experienced and related to one’s own story. (CCRS notes). Vatican II’s desire was to restore the sacraments back to the centre of Church life. The earliest celebration of the Eucharist were home Masses (Acts 2:46 says ‘they broke bread at home’) even with small numbers these early Christians were establishing the traditions for the future. There is clear evidence of Christ in the Eucharist. There is clear evidence of his unconditional love. What makes the bread sacred is not magic but the reality of the words. (Huebsch 1989). â€Å"For I received from the Lord what I also passed on to you: The Lord Jesus, on the night he was betrayed, took bread, and when he had given thanks, he broke it and said, â€Å"This is my body, which is for you; do this in remembrance of me.† In the same way, after supper he took the cup, saying, â€Å"This cup is the new covenant in my blood; do this, whenever you drink it, in remembrance of me.†(Corinthians 11:23-30) The bread and wine for the early Christians was much more than a meal, it was a coming together of the  community of God, each time a reference is made about the bread or the wine it is a reference to the people of God. For Huebsch the early Christians like us today are accepting the whole community of God when receiving communion, all his people with their strengths and weakness. An important development for the celebration of the Eucharist was the movement from the ‘home Mass’ of the very early Church to the Eucharist of the larger p ublic buildings. The large basilicas allowed for processions. Sunday became a holiday, giving more time for Christians to celebrate. Liturgies became longer and more elaborate. In these early days, the celebrant at the liturgy had considerable freedom to compose their own prayers for the Mass. Soon, however, standardisation set in, as the various communities began to adopt the prayers of their more articulate celebrants. (Kellly:1998) In the Fourth century, Constantine’s toleration of Christianity (313) led to its rapid spread throughout the Roman Empire. This led to significant changes in the celebration of the Liturgy. Latin became the standard language of the liturgy. At first, the assemblies met in basilicas later they built and dedicated churches and the clergy grew in numbers. During this era, they began to wear special clerical clothes. The sacrificial aspect of the Eucharist grew in importance, while the meal symbolism faded into the background (Kelly: 1998). This period stressed Christ’s divinity; this led to the people feeling less worthy to approach the Lord. As a result, there was a decline in the reception of communion. Theologians in the Middle Ages debated the meaning of the â€Å"real presence† of Christ in the Eucharistic bread and wine. They used the term transubstantiation to describe the mystery of the bread and wine being changed into Jesus’ risen body and blood. The stress was on the sacrificial nature of the mass. There was a growing sense that the laity were spectators to a drama unfolding on the altar. This led to a feeling that the consecration was the high point of the Mass. Emphasis fell, not on receiving Jesus in communion, but on seeing and adoring the Eucharistic Lord. Since fewer laity were receiving communion, a small round wafer (called host) substituted the traditional loaf of bread. (CCRS notes). As so few were receiving Holy Communion, the Fourth Lateran Council (1215) passed a law that re quired Catholics to receive communion at least once a year. Practices that focused on Eucharistic devotion began to appear. These included Elevation of the Host  and chalice at Mass. The priest had his back to the people, he had to hold the host and chalice up high. People would sometimes call out, â€Å"Hold it higher, priest.† Some were so keen on this practice they would run from one church to another just to be there for the moment of consecration! (O’Deasss 2013) .The Eucharistic prayer was recited silently by the priest except for the words of consecration which were voiced a little louder but not so loud as to be heard by the people because the people couldn’t hear the Eucharistic prayer, and even if they could they would not understand the Latin, many filled in the time by reciting the rosary or other devotional prayers during Mass. (O’Deasss 2013) The sixteenth century brought about the Protestant Reformation. The Council of Trent (1545-1563) met to correct some of the abuses that had crept into the Church. It also defended some Catholic beliefs attacked by the Reformers. In the area of the Eucharist, the church fathers reaffirmed the real presence of Jesus and the adequacy of the theological term, transubstantiation. They also defended the sacrificial nature of the Mass against the Reformers. Most significantly, Pope Pius V published a Roman Missal (1570) to bring uniformity to the official ritual. The Church then used this for the next four hundred years. (CCRS notes) Since the reform of 1570, a lot more was discovered about the Eucharist of the early Church and this enabled Vatican II to restore the liturgy more accurately to the traditions that had been lost. Vatican II’s key document the Constitution on the Sacred Liturgy (1963) led to the renewal of all the Sacraments. Important changes that we take for granted today include the following; celebrating the Mass in the vernacular language so we can understand more fully what it means; the Liturgy of the Word has greater importance; Guidelines instruct the homilist to develop the homily based on the readings. The Sunday readings revolve around a three-year cycle; this emphasis has helped Catholics discover the scriptures. The altar now faces the people, this invites a clearer understanding of what is going on at the Eucharist, and it also symbolically opens the Mass to fuller participation by all those present. Today’s Mass includes the Prayer of the Faithful, which links the Eucharistic worship to the whole church, the world, and the suffering in the community. Active congregational participation is an important feature of the post-Vatican II liturgy. Before, we commonly spoke of â€Å"attending Mass.† Today, we emphasise, â€Å"celebrating the Eucharist.† The  Mass is not a private affair. It is public worship in which the community, led by the priest, joins in thanking, praising, and adoring God together. The laity assumes many ministerial roles today, for example, as readers, Eucharistic ministers, choir members, greeters, and gift bearers. Vatican II wished to make the Eucharist a celebration of the entire community. Many of the reforms help us better understand the symbolism and meaning of the mass. They also help us gather together as a worshipping community. (Kelly 1998). Pope John Paul 11 mentioned this vital connection when he stated: â€Å"the Eucharist makes the Church and the Church makes the Eucharist.† The council did encourage changes in the liturgy. However, many people have misinterpreted this message and have down played the importance of the Eucharist in the Church and in our personal lives. Some members of the Church will claim that this council stated that the Eucharist is merely a symbol, thus denying the Real Presence. On the contrary, almost every Vatican II document speaks of the Real Presence, and implies that we need to increase our devotion to Jesus in the Blessed Sacrament. â€Å"Really sharing in the body of the Lord in the breaking of the Eucharistic bread, we are taken up into communion with him and with one another.† (Dogmatic Constitution on the Church (Lumen Gentium) 1963) This essay has traced the development and celebration of the sacrament of the Eucharist from the early Christian Church and has demonstrated that the focus at this time was sharing, participating, celebrating and making a personal connection with God. It has also explained that since the establishment and development of the early Catholic Church, the real meaning of the Eucharist was lost and people no longer felt connected to the sacraments. They were observers in the church rather than taking an active role. Since the Second Vatican Council, the Catholic Church attempted to involve the people and encourage them to experience Jesus’ real presence through the sacrament. â€Å"In brief, the Eucharist is the sum and summary of our faith. Our way of thinking is attuned to the Eucharist, and the Eucharist in turn confirms our way of thinking.† (1327 Catechism) The celebration of the Eucharist is a call, a call of the risen Christ who continues to give himself to us calling us to his banquet, through this celebration we can participate in our faith more richly. As Pope Benedict  explained so passionately: â€Å"I encourage you all to discover ever more fully in the sacrament of Christ’s sacrificial love† (Paclva 2013). Bibliography Catholic Church.

The Disputations Preacher

Known by the name, Girolamo Savonarola, he was born in 1452 Italy, however, different sources give varied accounts of his native town, some say it is Ferrara while others say it is in Occhiobello, which is 7 km from Ferrara. A man whose life was controversial, dramatic as well as tragic. Savonarola left a mark as a man who cared nothing for dictatorial protocol and official pretense. At Ferrara University, he took his undergraduate studies in Arts. He initially portrayed his feeling on morally corruption among the clergy, at the age of twenty, when he took them head on in his poem titled De Ruina Mundi (on the fall of the world). hich bespoke the destruction of the world. Hot on its heels came another poem in 1475 named, De Ruina Ecclesiae (on the downfall of the church). It is here that he portrayed his contempt of the Roman curia by defining it as ‘a false whore'. Savonarola went on to join the Dominican congregation in the year 1475, where he entered the San Domenico convent at Bologna. This coincided with the Italian Renaissance . Savonarola immersed himself in his studies with zeal, this saw him transfer to the Convent of Santa Maria Degli Angeli in 1479. In 1482 he was deployed by the oder to what came later to be known as, the city of his destiny- Florence. People bemoaned his ungainly character and poor oratory skills. The impression he made of himself on the people of Florence was so dismal that, they never noticed his eventual departure in1487. This took him back to Bologna, where he went on to become the master of studies. Savonarola went on to preach on prophesies he had, such as the occupation of Florence by the French. He went on to become more, outspoken and took a hard stance that sometimes ended making him some kind of a misfit among the people. He believed in the classification of issues and actions in only two categories: the good and the bad. Savonarola, was later to fall into bad books with the orders of the catholic church. This led to he excommunication by the pope ,who was later to authorize his arrest. All this was later followed his arrest, torture, prosecution and eventual execution,on grounds of heresy sedition and for proclaiming prophetic statements. His execution took place in 1498 where he was burnt at the stake alongside his two ardent disciples. It is important to note that Savonarola remained defiant onto death. This is attested to by the fact that even though he wrote a confession, he followed it with a meditation, where he pleaded with God to forgive him for pleading to sins he did not commit. Different schools of thought view Savonarola differently, however all agree that Savonarola is one big disputation theme for all and sundry. Savonarola's thinking later on came to be known as not only a way of thought but also a guiding light for both conservatism thinkers and reformists. cholars have look at the Savonarola way of thought, as a linchpin for serous revolutionary discourse as well as a reason for serous research and study into the history of disputation theory. Either way it is looked at, the Savonarola way of thought can serve any of the above purposes depending on the interest of the one examining it. (Polizzotto, 1995) describes how followers of Savonarola had influence that permeated every facet of Florentine life . This was during the important happenings that saw the transition of the city on from republic to principate. In his words, their ideology and activities offer the key to demystifying both the political happenings of the latter years of the Florentine Republic, as well as the nature of contemporary political debate. It also gives an insight into the characteristics of the merging Medicean Principate. DISPUTATION This was a preaching method commonly utilized by the Dominicans. It employed a system of thesis, antithesis and synthesis. It was manly distinguishable from methods by its clashing of ideas. This was the academic background from which Savonarola emanated. (Hazel,n. d. p. -17) puts it ‘like his Dominican contemporaries, the young Savonarola was trained in the disputation method, and it has a marked influence on his style of preaching'. In examining the Rhetorical influences that surrounded Savonarola in his formative days, we can form a good idea of the facets of a good renaissance discourse. For Savonarola the summon was the most effective tool of bringing about moral reform. H is tendency to rely on the summon for moral reform can be attributed to the fact that he was a Dominican. Dominicans have gone down in history as strong believes in rhetoric and disputation Savonarola though came to believe in his oratory skill almost by pure accident He initially experimented with rhetoric, to very successful results much to his own consternation. (Hazel, n. d, p. 4-17) one incident confirmed his power to him. While traveling the seas on a boat, he noticed a bunch of soldiers gambling using dice and cards. He so furiously denounced this activity with such bitterness that they stooped the gambling, much to his own surprise. This vitriolic manner would be the benchmark of his future preaching. Savonarola derived most of his rhetoric effectiveness from the fact that he was perceived as a prophet by many. He was more of what could today be regarded as a doom sayer. His passionate way of preaching eventually earned him very ardent supporters, who later came to play a very pivotal role in determining the success of his campaigns. Savonarola followers were compelled to develop a way by which to survive the turbulent times and be able to carry on their campaign of trying to fight what they believed to be moral decadence. SAVONAROLA AS AN EXAMPLE OF RESISTANCE TO ORGANIZATIONAL CHANGE IN CONTEMPORARY ORGANIZATIONS. Savonarola came into the picture in the immediate post renaissance period. his was a time marked by reduced enforcement of the doctrines. It was a period of widespread immorality and more so, among the proletariat. The church orders were also not spared the widespread liberalism in the church at the time. The church was going through a period when it had relaxed its stand on the usage of disguises, jewelery and other such adornments. He got a huge following of a group that he ca lled the weepers. This group went through the city, raiding houses for paintings, jewelry, mirrors, combs and all that they considered unbecoming of good followers of the religion. The passion with which he defended his views was infectious and convincing enough to earn hims the attention of the masses. He further utilized his rhetoric to have people convinced that whatever he was speaking was bound to happen. since the first instance when he convinced the soldiers of the illegitimacy and the immorality of the act they were engaging in, he got convinced of the ability to sway peoples thoughts. The benchmark of the rhetoric of Savonarola is the ability to draw parallelism, between the acts people are engaged in, and prophecies or documentation, or practices of hither. During his mission to return the people into the accepted practices, or the practices he viewed as acceptable, he had to use rhetoric effectively. Rhetoric served as such a powerful and effective too since as it is stated that it went a long way into attracting meaningful attention. Savonarola viewed the pope as a big failure in allowing the insurgence of renaissance. This was the foundation of his thinking that the pope, was a major hurdle in his efforts to marshal people, back to the accepted and traditionally practiced doctrines. Kreis, 2000) Savonarola viewed himself as an instrument of God, and and did not believe in anything deterring him– not even Lorenzo the Magnificent, could stand in his way. He envisioned the reconstruction Florence as a â€Å"respublica Christiana,† a Christian republic, a republic in where allegiance was to the true sovereign God and God alone. This resentment to the establishment was particularly informed by the fact that, Pope Alexander I V had two illegitimate children, which were an obvious testimony of his wayward behavior. All the sane this was not the only informing idea behind Savonarola's vehemence. The commitment of the Pope to renaissance gave him a curious mix of both the earthly and the religious. To the conservatism this was a clear and sure show of moral rot and if condoned was bound to bring doom to all and sundry. The biggest challenge that was facing the conservative was in trying to turn people around to their way of thinking, and to fuel sufficient phobia of doom in the people. This activity was also faced by another challenged in that, the church and the ruling powers of the society were so much intertwined. Therefore for the conservatives to effectively combat the newly adapted and overwhelmingly accepted way of life, they had to wage a battle and sustain in long enough to sway a good following. Both the religious (Pope) and the social (Medici) authorities therefore fell in the bad books of the conservatives. The question of the most effective method of achieving this was then the only answer he had to seek out. Here rhetoric through preaching became the way out and as (Hazel,n. d p. 4-17) puts it Savonarola was opposed to both the Medici and the Pope. He used his rhetoric though preaching to stir up resentment to both the Medici and the Pope. The two were a very then powerful ruling coalition. The question that is likely to arise is: how was this possible?. Savonarola painted such a grim picture of the impeding damnation and the inferno of hell. He used his rhetoric so effectively that he painted a picture, grim enough to sway even the staunchest of souls. However for the Medici he was to be viewed with suspicion as a man preaching the return to the morality of the medieval times that they were trying to move people from. This unprecedented opposition of the ruling coalition earned him many supporters In contemporary organizations these days, rhetoric can be a very effective in resisting change. However there are some very basic requirements that must be met in remaining true to the Savonarola example. First and most important, the originators and the propagators of the rhetoric must be fully convinced of the philosophies that inform their rhetoric. This is attested top by the Savonarola example, in that, in as much as there was very stiff opposition to his stance in issues of morality and the tenets of religious beliefs, he stood his ground. This is despite the fact, that he was fighting what could be correctly termed as, a David versus Goliath battle against the powerful ruling coalition, comprising of the Medici and the Pope. The perpetrators of modern day rhetoric who desire to attain any meaningful success in fighting changes in institutional structures also ought to stand their ground. They also ought to be fully aware of the exact parameters within which their arguments and their expectations lie. This is shown in Savonarola's depiction of authority as put in the words of ( Hazel,n. Savonarola draws parallelism between the sinners of those days and the merchants who Jesus whipped while they were trading in the temple. In as much as the traders had permission from the Jewish leadership, Jesus on his side was heeding a higher decree from the father. Savonarola therefore advises his followers to act like Jesus and defy the regulations from the rulers since they do not augur well with the biblical teachings. The convic tion with which you defend you arguments is perhaps defined by the manner in which Savonarola defended his. Savonarola is known to have defended his stand all the way to grave, this is evident in the way he wrote down meditations to the effect that, he prayed to God for forgiveness. He sought forgiveness for confessing to sins he felt he wasn't guilty of. The disputations of Savonarola are very vital in highlighting the effectiveness of rhetoric which is backed by conviction. The passion that is a key requirement especially in such contradictory situations plays a key role in the swaying of the peoples way of thinking. Many are the times, when very passionate public, speakers who are actually trying to sell ideas, that could otherwise have been viewed as vague, have been accepted instead of their more informed yet less passionate counterparts. A good example of passionate public rhetorician is one catholic priest by the name of Charles Coughlin of the 1930. He spoke co passionately about the occurrences of the time on public radio that he gained a very wide public audience. This is not withstanding the fact that he was talking about the normal happenings. It is however important to note that he used to approach these arguments with passion and controversy. The rhetoric however is always effective if ,and only if it is directed. This was a real highpoint of Savonarola. He directed the gall of his rhetoric towards the failing of the ruling elite and the church leadership. The modern times rhetorics especially those opposed to institutional changes normally make informed attacks of specific institutions, people, or activities in trying to give ground to their rhetoric. This has been demonstrated in most cases in instances when the perpetrators of rhetoric have painted grim pictures of doom in the peoples minds, if the organizations do not remain the way they are. However this directed criticism has to be informed by facts that cannot be easily disputed. This was the case in the instance when the followers of Savonarola knew for a fact that the deeds they were fighting against were realities that could not be contested. The other key reason for any rhetoric to be effective is its being backed by action. In any resistance to organizational changes. Actions can always play a key role in swaying people into thinking your way. This is actually a very vital display of conviction and commitment to the cause. In as much as power of rhetoric delivery is likely to earn one good following, resistance to institutional change is actually a major challenge. Savonarola backed his rhetoric with radical actions and these were both bold and rampant. The adherents of his rhetoric alongside him, attacked all that they thought represented the rot in the church. They also attacked and burned all that was associated with the laxity that came with the renaissance, This was the hallmark and the culmination of his disputation rhetoric. Groups of youths that were drawing inspiration from him roamed the city in vigilante groups, they collected all that was associated with the demeaning change and burnt them at what later came to be called the fire of vanity. This eventually convinced the people that the disputationist had a case, they therefore swayed their stand and started following him in larger numbers. However it is of importance to note that, any action taken in the efforts to resist the advent of change should be taken with a lot of moderation. This is due to the fact that the extreme tends to shock people into resting the efforts directed at resisting the change. This can be justified by the case of what eventually happened to Savonarola. The activities of people being held at ransom by marauding youths led to resentment amongst the people. This was also due to the fact that the people felt that they were denied the pleasures of the changing times. The other failure was due to lack of moderation in public displays of allegiance to the French. Savonarola sided with the French in their occupation of the city of Florence, this landed him inn bad books with the populace. It is therefore of essence that in passion in resisting organizational change ought to be metered and moderated. In modern times leaders who try to resist change using rhetoric should be guided by the principle of moderation and public acceptability of pronouncements and deeds. This can enhance a steady yet acceptable and successful resistance. The people following Savonarola also required to have regulations, this was however a major failing of the Friar which eventually was instrumental in occasioning his downfall. THE DISPUTATION PREACHER AS A CATALYST FOR ORGANIZATIONAL CHANGE. Savonarola has widely been depicted as big resistance and a conservatist. He was known for resisting the changes that the proletariat were introducing into the thinking of the people and the church. Much as all this is true, he can as well be observed as a person who played a pivotal role in awakening peoples thinking and perception of hierarchy and stipulations. Savonarola came into the picture during a time when the Pope and the Medici had such a cordial and strong relationship. It was during the time when a decree from the pope was treated as law. Great lessons on effective change can be learnt from the preacher. First he openly opposed the moral rot in the religious orders at that time. The eventual reformation that took place in the orders of the church, that eventually led to the protestant movement, were not a mere accident. We can not also, exclusively say that they, emanated from the Ninety five theses that were authored Martin Luther. They started all the way with the public denunciation of the proletariat by Savonarola. It ought not to escape our attention that such deeds as these call for guts and conviction. Therefore Savonarola was key in starting the reformists thinking that saw major changes in the church. Similarly the contemporary leaders of the day could borrow a leaf from the stance of Savonarola and stand their ground in the face of such daunting tasks. This can point people in the right direction if the strong and vitriolic rhetoric is to be used effectively. If such tactics are used then much can possibly be accomplished. his will all be a catalytic role since just like Savonarola accomplices will be essential for the wider goal to be achieved. The use of rhetoric to instigate social change also ought to be well informed and guided by the need for general good of the involved society. It is in this respect that Savonarola was able to obtain a good following. In the first instance, he painted a very gr im picture of the realities facing the people. Painted a very dull picture of what awaited the people in in future. With this clearly understood, he prodded people into following him into a revolution that was to same people from the inevitable eternal damnation. People followed his advice since they felt that by so doing they could evade the oncoming apocalypse. It is in this light that, the contemporary leaders in the current day organizations, ought to inform people of the doom awaiting them in the future if the present is not well dispensed with. They need to match the rhetoric so stated with words leads the people to revitalize and energize their need to do good. The driving force behind this need to do good is the underlying fact that the good is like a boomerang. The thinking and speech of Savonarola was clearly against the grain and the activities of the time. He brought to the fore the failings of a papacy which very many revered till then. True to form, the contemporary leaders of these days are supposed to give room for fresh, radical and new ways of thought. This can be a vital way of energizing peoples thoughts. not all that is radical or new is bad. this was clearly shown in Savonarola's time. In as much as Savonarola fell into bad books and was eventually hanged, he was right in several claims. For example he argued that the Vatican had turned into a den of prostitution, this was right due to the fact that the pope was outright promiscuous. Therefore people ought to be allowed free reign of thought and encouraged into offering new ideas. Rhetoric is good tool of encouraging and enhancing involvement of the masses into peoples activity. This is shown in how effectively Savonarola was able to cajole the people of Florence into feeling a s part of his vision. (Hazel, n. d) he reverts to his analogy of Christ driving money changers out of the temple with ropes. He sees his tongue as the major ropes and then asks people to be the other smaller ropes with which to drive out the church officials. In this way he manges to fit the people into the picture. hey now feel like they are part of the battle against the moral rot. They therefore are given the feeling that they have a role to play in driving the agenda forward. The contemporary organization leaders these days ought to adopt the same attitude, if their rhetoric is going to be effective. There is need to orient people into feeling that they belong to the wider picture. The ability to integrate the people in the people into the picture helps in creating a progressive force . The ability to have people working in tandem for a common goal as well helps in increasing the peoples resolve to do things together and do them well. The protests that Savonarola mounted were three pronged, they addressed the three major issues of the society. He addressed the love for splendor and money, hence the economy. He addressed the prophetic revelations he had, hence religion. Finally he addressed the failure of the Medici hence he addressed the political administration. Therefore for any modern rhetoric to be effective, if Savonarola is to be used as a benchmark, the modern leaders ought to address and effectively so, the above three major issues. The effective handling of these three makes a wholesome and effective approach in any Rhetoric. CONCLUSION Modern users of rhetoric ought to put in mind and effectively integrate the Savonarola approach. this is a sure way of ensuring efficiency. little has been said about the good that was raised by the rhetoric of Savonarola, however a lot can be learnt from his approach. His approach was very much in line with the accepted and very much utilized approaches to rhetoric. In modern times the approach to the rhetoric always uses the same reasoning as the guiding light. Effective address of the issues at hand ought to be a key consideration in the delivery of rhetoric. Zeal and passion are also key in the delivery. The interplay between such delivery and well planned out actions increases the effectiveness. Disputation also serves as a good way of engaging the thinking of all and sundry. Disputation though tends to be more of and elitist approach which can be a major impediment to the engagement of masses in a discourse. However it is more effective since it is more mind engaging and provokes more insightful thinking. Many a times different people have used rhetoric effectively. This has always produced wide mass following and public acclaim. The key lies in following Savonarola's example, and like he did, appealing to the emotions. Rhetoric and disputation world over have been very effective in instigating radical changes to any systems that are publicly accepted and acclaimed. For one to effectively utilize the same, it is essential to familiarize with the users of yesteryears and know how effectively they did so. To say that Savonarola was simply effectively with his rhetoric would be an understatement.

Heap vs. Stack for Delphi Developers

Heap vs. Stack for Delphi Developers Call the function DoStackOverflow once from your code and youll get the EStackOverflow error raised by Delphi with the message stack overflow. ​function DoStackOverflow : integer;begin result : 1 DoStackOverflow;end; What is this stack and why there is an overflow there using the code above? So, the DoStackOverflow function is recursively calling itself without an exit strategy it just keeps on spinning and never exits. A quick fix, you would do, is to clear the obvious bug you have, and ensure the function exists at some point (so your code can continue executing from where you have called the function). You move on, and you never look back, not caring about the bug/exception as it is now solved. Yet, the question remains: what is this stack and why is there an overflow? Memory in Your Delphi Applications When you start programming in Delphi, you might experience bug like the one above, you would solve it and move on. This one is related to memory allocation. Most of the time you would not care about memory allocation as long as you free what you create. As you gain more experience in Delphi, you start creating your own classes, instantiate them, care about memory management and alike. You will get to the point where you will read, in the Help, something like Local variables (declared within procedures and functions) reside in an applications stack. and also Classes are reference types, so they are not copied on assignment, they are passed by reference, and they are allocated on the heap. So, what is stack and what is heap? Stack vs. Heap Running your application on Windows, there are three areas in the memory where your application stores data: global memory, heap, and stack. Global variables (their values/data) are stored in the global memory. The memory for global variables is reserved by your application when the program starts and remains allocated until your program terminates. The memory for global variables is called data segment. Since global memory is only once allocated and freed at program termination, we do not care about it in this article. Stack and heap are where dynamic memory allocation takes place: when you create a variable for a function, when you create an instance of a class when you send parameters to a function and use/pass its result value. What Is Stack? When you declare a variable inside a function, the memory required to hold the variable is allocated from the stack. You simply write var x: integer, use x in your function, and when the function exits, you do not care about memory allocation nor freeing. When the variable goes out of scope (code exits the function), the memory which was taken on the stack is freed. The stack memory is allocated dynamically using the LIFO (last in first out) approach. In Delphi programs, stack memory is used by Local routine (method, procedure, function) variables.Routine parameters and return types.Windows API function calls.Records (this is why you do not have to explicitly create an instance of a record type). You do not have to explicitly free the memory on the stack, as the memory is auto-magically allocated for you when you, for example, declare a local variable to a function. When the function exits (sometimes even before due to Delphi compiler optimization) the memory for the variable will be auto-magically freed. Stack memory size is, by default, large enough for your (as complex as they are) Delphi programs. The Maximum Stack Size and Minimum Stack Size values on the Linker options for your project specify default values in 99.99% you would not need to alter this. Think of a stack as a pile of memory blocks. When you declare/use a local variable, Delphi memory manager will pick the block from the top, use it, and when no longer needed it will be returned back to the stack. Having local variable memory used from the stack, local variables are not initialized when declared. Declare a variable var x: integer in some function and just try reading the value when you enter the function x will have some weird non-zero value. So, always initialize (or set value) to your local variables before you read their value. Due to LIFO, stack (memory allocation) operations are fast as only a few operations (push, pop) are required to manage a stack. What Is  Heap? A heap is a region of memory in which dynamically allocated memory is stored. When you create an instance of a class, the memory is allocated from the heap. In Delphi programs, heap memory is used by/when Creating an instance of a class.Creating and resizing dynamic arrays.Explicitly allocating memory using GetMem, FreeMem, New and Dispose().Using ANSI/wide/Unicode strings, variants, interfaces (managed automatically by Delphi). Heap memory has no nice layout where there would be some order is allocating blocks of memory. Heap looks like a can of marbles. Memory allocation from the heap is random, a block from here than a block from there. Thus, heap operations are a bit slower than those on the stack. When you ask for a new memory block (i.e. create an instance of a class), Delphi memory manager will handle this for you: youll get a new memory block or a used and discarded one. The heap consists of all virtual memory (RAM and disk space). Manually Allocating Memory Now that all about memory is clear, you can safely (in most cases) ignore the above and simply continue writing Delphi programs as you did yesterday. Of course, you should be aware of when and how to manually allocate/free memory. The EStackOverflow (from the beginning of the article) was raised because with each call to DoStackOverflow a new segment of memory has been used from the stack and stack has limitations. As simple as that.

Traditional Management Systems VS. CRM And SCM Essay

Traditional Management Systems VS. CRM And SCM - Essay Example The paper shall first compare traditional management with CRM in the first section then secondly, it shall compare traditional management with SCM. In conclusion, it is evident that both customer relationship management systems and supply chain management systems create increased efficiency, achieve more costs savings and generate greater profits for organizations that implement them. Customer Relationship Management (CRM) is a strategy used to learn more about customers’ needs and behaviors in order to solidify their loyalty to the business’s offerings (Wailgum & Patton, 2011; â€Å"What Is CRM?,† 2010). This strategy enables businesses effectively utilize their resources to increase their knowledge of the behavior and value of their target customers. This increased insight enables businesses to identify and target the best customers, customization and/or personalize their products and services, track customer contacts, add cross-sell and upsell opportunities, reduce costs and increased overall profitability. CRM may mean different things to different industries but, ultimately, its purpose is to help organizations derive competitive advantages that will sustain their long-term profitability. This section shall differentiate traditional management systems from CRM in terms of differences in approaches, achieving efficiencies, costs savings, a nd firm profitability. Differences in approaches (empowering customers, becoming a trusted partner) A good example that could be used in comparing traditional management systems with CRM is the marketing function of an organization. Under traditional management systems the marketing was product-based and company focused. Management was more concerned with how much control they have on the message conveyed to the customer. In these cases the company was the active participant in the marketing process whereas the consumer was inactive or passive. In contrast under CRM, customers are empowered for example Dell customers can configure their computers prior to ordering through Dell’s website. CRM enables companies to ensure that only those products or services that consumers want are produced. This alters organizations’ marketing strategies from the traditional push to pull strategies. Furthermore, the increased consumer participation that is encouraged by CRM enables organ izations to understand their customer requirements better. This makes organizations that have CRM become more trusted partners than those firms that are stuck on traditional management systems. Achieving efficiencies CRM management systems are generally supported by information and technology (IT) solutions that are designed for the unification of customer information (Kumar, 2011). Where these solutions are well integrated with other business systems in an organization and /or with partner organizations, the company can be able to centralize all its customer information in a few IT applications. This means that senior management can easily be presented

Strategic Solutions Essay Example | Topics and Well Written Essays - 500 words

Strategic Solutions - Essay Example In Apple Inc., executives take advantage of a large number of college leavers by offering them low wages compared to their contributions besides denying them other employment benefits like commissions. In addition, despite Apple being among well-paying companies, wages paid to employees do not correspond to the sum the fetch for the company, hence the saying ‘Long on Loyalty but Short on Pay’.Most of the Apple’s capital is in the pockets of few, hence leading to wealth inequality in the country. The company does not provide job security too because an employee’s period in the company is very short-lived, mostly two and a half years. This is to the extent of quitting employment in Apple retail shops seems to be the best option for most employees due to the high rate of exploitation in the company. Correspondingly, Apple does not offer commissions to its workers and limits time for taking breaks. Although all this happens to create more wealth, employees earn less while key managers pocket large sums of money. At some point, the majority of employees realize that they will not rise as high as they can due to these limitations. This renders most of them becoming demoralized because they are not seeing any future advancements in the company.As exposed in the video ‘Wealth inequality in US’, local citizens work tirelessly towards enriching themselves in numerous corporations but end up earning less. Much wealth goes into the pockets of a few people holding high positions in these corporations.

Newborn case study Example | Topics and Well Written Essays - 500 words

Newborn - Case Study Example The normal respiratory of an infant is usually between 30 and 60 breaths/min. In Baby Cunningham’s case, the respiratory was significantly high as a result of the respiratory distress syndrome. She was also preterm, and her lungs had not fully matured. Baby Cunningham’s temperature was significantly low at 96 degrees. The American Academy of Pediatrics shows the normal range of temperature for newborns to be between 97.7 and 99.3 degrees Farenheight. The main cause of the low temperature can be attributed to the fact that she was preterm, and her subcutaneous tissue had nod developed completely. Normal blood glucose levels in a neonate is recommended at a minimum of 30mg/dl. The blood glucose levels in Cunningham’s case was 25mg/dl one hour after birth, below the recommended level. If not corrected, it can result in symptoms of hypoglycemia such as apnea, tremors, seizures, lethargy, cyanosis and poor feeding (Adamkin, 2011). Respiratory distress syndrome is characterized by several symptoms, most commonly tachypnea, nasal flaring, grunting and retractions. These symptoms are due to the difficulty in breathing, and they are managed by relieving the underlying cause. Treatment involves supplying oxygen, mechanical ventilation, surfactant replacement and supportive care. The environmental temperature can influence the chances of survival of baby Cunningham. Since she is already hypothermic and has difficulty controlling her body temperature, it is recommended to put her in a warm environment as a management measure. Due to the complications of the elective induction and the caesarean section, Cunningham was exposed to infection and, therefore, it is important to determine if she has an infection to avoid further health complications. The situation in Cunningham’s birth could have been easily avoided by waiting for her to complete her gestation period. A full term infant has got higher chances of survival as compared to a preterm. Complications can

Hitler's greatest mistake Research Paper Example | Topics and Well Written Essays - 750 words

Hitler's greatest mistake - Research Paper Example Hitler was very much overconfident about invading Russia. The troop was not provided with winter clothing or equipments. More than half of Germen troops were frozen to death. The invasion was started on three fronts, in the south towards the Ukraine, in the north towards Leningrad, and centre towards Moscow. The moves were initially considered as successful advances. Within few days the Luftwaffe achieved air supremacy. German troops started encircling Russian defenders. Nazi legions soon conquered 1200 tanks and 600 big guns. They also gained more than 150,000 prisoners. Hitler attempted to control Russia to a great extent. Their crucial aim was to gain control over Leningrad-Moscow-Volga line. Germany’s three-pronged invasion was intended for seizing production areas in Ukraine and the Donetz basin. Germany’s plans were to acquire mineral deposits, oil and grain. They attempted to capture the Black and Baltic seas. Russian citizens were encouraged to accept the ‘scorched policy’. They were instructed that if they were forced to evacuate from their place they should not leave anything behind. They should evacuate fully. Germans at the same time started feeling trouble as weather was becoming disadvantageous for them. Russian partisan groups were gaining strength as they began imposing big tolls on supply convoys. Germans gained control over Riga, Smolensk and Kiev. They invaded Stalingrad to acquire the oilfields of Cacasus in August 1942.

Individualism Essay Example | Topics and Well Written Essays - 1000 words - 2

Individualism - Essay Example The major schools of thought can be broken down into biocentrism, sentientism, ratiocentrism and anthropomorphism (weak and strong). In attempting to discover which of these views is most justified, it is necessary to understand the basic ideas each school of thought represents. Biocentrism is, roughly speaking, a system in which the criterion for inherent worth is based upon the simple-seeming criterion of whether one lives or not. Because all living things have the right to exist, we, as thinking beings, hold moral responsibility to ensure that we do not interfere with this right. â€Å"[Taylor] contends that in addition to our moral obligations toward our fellow humans, we also owe duties to wild living things in their own right †¦ He agrees with Goodpaster’s argument that one can deny that non-humans have rights and yet hold that they are moral patients toward whom moral agents have duties and responsibilities† (Kocer, 2001). Being the center of a life force is grounds enough to fulfill to the biocentrist viewpoint, but this introduces problems as one must consider that all life forms must hold inherent worth equally – the human as well as the cockroach – despite obvious differences in understanding and awareness. As even Taylor hints, there must be something more to the question than simply the idea that one respirates and reproduces. This is where the ideas of sentientism arise. While philosophers such as Singer suggest that this term is applied to any creature that demonstrates capacity to feel pleasure or pain, â€Å"the term ‘sentient’ refers more broadly to consciousness of something or other, rather than to consciousness of pleasure and pain specifically† (Jamieson, 2003: 192). However, when it is applied in this sense, it is usually limited to the view of something being able to express it is feeling pleasure or pain. Under this view, things gain inherent

The European Union and NAFTA Assignment Example | Topics and Well Written Essays - 1250 words

The European Union and NAFTA - Assignment Example The union which includes among other countries the United Kingdom, Netherlands, Germany, Greece, Austria, Denmark, and Finland was established in the early 1950s (Bomberg, Peterson & Corbett 2012, p. 6). The six founding members of the union include West Germany, the Netherlands, Italy, Luxembourg, France, and Belgium. The union is basically an organization that brings together member states for political and economic reasons. The EU operates through intergovernmental negotiations and is governed by a number of supranational independent institutions (Bomberg, Peterson & Corbett 2012, p. 15). The main institutions that govern the union include the European Central Bank, the European Council, the European Commission, and the European Parliament, just to name a few (Corbett, Jacobs, Shackleton 2011, p. 7). The European Union traces its roots to the period following the Second World War when six countries sought to join forces with the aim of prevention the possibility of war between the mselves (McCormick 2007, p. 64). Under the European Coal and Steel Community banner, the member states agreed to pool national heavy industries thereby eliminating potential conflicts relating to the scramble for raw materials (Bomberg, Peterson & Corbett 2012, p. 18). ... In 1993, the European Union was formally established with the signing of the Maastricht Treaty. Ever since the establishment of the European Coal and Steel Community, the European Community has continued to expand in size and, therefore, power. The European Union has seen its member states cooperate in various ways (Smith 2007, p. 63). At least 12 of the countries have fully adopted the Euro as their national currency, a factor that has seen the easy flow of trade activities between the member countries. Other states use the Euro together with their national currencies to effect transactions. The Union demands that member countries fulfil a number of conditions before they can be formally admitted to the organization (Bomberg, Peterson & Corbett 2012, p. 45). By its demand that member countries and potential members be politically stable and have a democratic government that respects the rule of law and human rights, the union is effectively playing a major role in establishing deep rooted democracy in the region and beyond (Bindi 2010, p.45; Barnard 2007, p. 83). The European Union and the United States of America cooperate in a number of fronts. However, there are cases when the two powers engage in tussles which see them grace the corridors of the World Trade Centre to seek resolutions to their disputes. Considering the need for greater cooperation in terms of trade, the two bodies have been considering instituting a formal agreement that will see them enjoy free trade between themselves (Sutton 2013, par. 1). In this respect, the Transatlantic Free Trade Area (TAFTA), which is currently at a proposal stage, is intended to bring together the two

Course Management Systems - Moodle Essay Example for Free

Course Management Systems Moodle Essay Moodle is an open-source course management system designed to host online courses and facilitate academic interaction between students and their instructors. The program was created by Martin Dougiamas, who formerly worked with WebCT. Because of this the program features many similarities to WebCT, but is more flexible overall due to its open-source nature. Moodle can be accessed via more than eighteen-thousand registered websites and is used by approximately eight million students worldwide. The program supports sixty-one languages as of November 2006 and is constantly expanding. Students simply download the program, register a username and connect using an enrollment key code provided by their professor. The site can host single teacher classes, or link various classes within an academic institution. Moodle also offers the option of designing complete lessons online, which can consist of class material as well as optional end-of-chapter review questions. Instructors have a variety of options for posting assignments on Moodle, and can set their own preferences on how student submitted files can be accepted for grading. Teachers have the option to allow students to upload files, including text documents of various formats as well as images. After grading the instructor has the option to post grades directly, as well as leaving comments regarding their response to the assignment. They can also format assignments for direct editing online, allowing students to type their response directly into the program and submit it for grading. Instructors can also use Moodle as an online grade book for assignments complete in class (offline), so that students can have easy access to their grades. Quizzes can be constructed and assigned to students in Moodle as well, with several format options available. Teachers can design tests consisting of various question formats, including multiple choice, true-or-false and short answer questions. They also have the option of giving students multiple attempts to complete the quiz, and can set other variables such as time limits (quiz is timed and may only be completed within the allotted time limit), or password protection to limit access. Students have a variety of options for interacting with fellow classmates as well as the instructors via chat, forums and surveys. They can also access course-relevant resources via glossaries (which can be student or teacher-defined) and a fully-interactive Wiki (user-defined encyclopedia).

Understanding Inventory Management And Its Theories

Understanding Inventory Management And Its Theories Inventory management or inventory control is an attempt to balance inventory needs and requirements with the need to minimize costs resulting from obtaining and holding inventory. There are several schools of thought that view inventory and its function differently. These will be addressed later but first we present a foundation to facilitate the readers understanding of inventory and its function. Inventory Definition Inventory is a quantity or store of goods that is held for some purpose or use (the term may also be used as a verb meaning to take inventory or to count all goods held in inventory). Inventory may be kept in house meaning on the premises or nearby for immediate use or it may be held in a distant warehouse or distribution center for future use. With the exception of firms utilizing just in time methods more often than not the term inventory implies a stored quantity of goods that exceeds what is needed for the firm to function at the current time (e.g., within the next few hours). Why we should keep inventory Why would a firm hold more inventory than is currently necessary to ensure the firms operation? The following is a list of reasons for maintaining what would appear to be excess inventory. MEET DEMAND. In order for a retailer to stay in business it must have the products that the customer wants on hand when the customer wants them? If not the retailer will have to back order the product. If the customer can get the good from some other source he or she may choose to do so rather than electing to allow the original retailer to meet demand later (through back order). Hence, in many instances if a good is not in inventory a sale is lost forever. KEEP OPERATIONS RUNNING. A manufacturer must have certain purchased items (raw materials components or subassemblies) in order to manufacture its product. Running out of only one item can prevent a manufacturer from completing the production of its finished goods. Inventory between successive dependent operations also serves to decouple the dependency of the operations. A machine or work center is often dependent upon the previous operation to provide it with parts to work on. If work ceases at a work center then all subsequent centers will shut down for lack of work. If a supply of work in process inventory is kept between each work center then each machine can maintain its operations for a limited time hopefully until operations resume the original center. LEAD TIME. Lead time is the time that elapses between the placing of an order (either a purchase order or a production order issued to the shop or the factory floor) and actually receiving the goods ordered. If a supplier (an external firm or an internal department or plant) cannot supply the required goods on demand then the client firm must keep an inventory of the needed goods. The longer the lead time the larger the quantity of goods the firm must carry in inventory. A just in time (JIT) manufacturing firm such as Nissan in Smyrna Tennessee can maintain extremely low levels of inventory. Nissan takes delivery on truck seats as many as 18 times per day. However steel mills may have a lead time of up to three months. That means that a firm that uses steel produced at the mill must place orders at least three months in advance of their need. In order to keep their operations running in the meantime an on hand inventory of three months steel requirements would be necessary. HEDGE. Inventory can also be used as a hedge against price increases and inflation. Salesmen routinely call purchasing agents shortly before a price increase goes into effect. This gives the buyer a chance to purchase material in excess of current need at a price that is lower than it would be if the buyer waited until after the price increase occurs. QUANTITY DISCOUNT. Often firms are given a price discount when purchasing large quantities of a good. This also frequently results in inventory in excess of what is currently needed to meet demand. However if the discount is sufficient to offset the extra holding cost incurred as a result of the excess inventory the decision to buy the large quantity is justified. SMOOTHING REQUIREMENTS. Sometimes inventory is used to smooth demand requirements in a market where demand is somewhat erratic. Consider the demand forecast and production schedule outlined in Table 1. Notice how the use of inventory has allowed the firm to maintain a steady rate of output thus avoiding the cost of hiring and training new personnel while building up inventory in anticipation of an increase in demand. In fact this is often called anticipation inventory. In essence the use of inventory has allowed the firm to move demand requirements to earlier periods thus smoothing the demand. Controlling Inventory Firms that carry hundreds or even thousands of different part numbers can be faced with the impossible task of monitoring the inventory levels of each part number. In order to facilitate this many firms use an ABC approach. ABC analysis is based on Pareto Analysis also known as the 80/20 rule. The 80/20 comes from Paretos finding that 20 percent of the populace possessed 80 percent of the wealth. From an inventory perspective it can restated thusly: approximately 20 percent of all inventory items represent 80 percent of inventory costs. Therefore a firm can control 80 percent of its inventory costs by monitoring and controlling 20 percent of its inventory. But it has to be the correct 20 percent. The top 20 percent of the firms most costly items are termed An items (this should approximately represent 80 percent of total inventory costs). Items that are extremely inexpensive or have low demand are termed C items with B items falling in between A and C items. The percentages may vary with each firm but B items usually represent about 30 percent of the total inventory items and 15 percent of the costs. C items generally constitute 50 percent of all inventory items but only around 5 percent of the c By classifying each inventory item as an A B or C the firm can determine the resources (time effort and money) to dedicate to each item. Usually this means that the firm monitors A items very closely but can check on B and C items on a periodic basis (for example monthly for B items and quarterly for C items). Another control method related to the ABC concept is cycle counting. Cycle counting is used instead of the traditional once a year inventory count where firms shut down for a short period of time and physically count all inventory assets in an attempt to reconcile any possible discrepancies in their inventory records. When cycle counting is used the firm is continually taking a physical count but not of total inventory. A firm may physically count a certain section of the plant or warehouse moving on to other sections upon completion until the entire facility is counted. Then the process starts all over again. The firm may also choose to count all the A items then the B items and finally the C items. Certainly the counting frequency will vary with the classification of each item. In other words an item may be counted monthly B items quarterly and C items yearly. In addition the required accuracy of inventory records may vary according to classification with A items requiring the most accurate record keeping. Balancing Inventory and Cost As stated earlier inventory management is an attempt to maintain an adequate supply of goods while minimizing inventory costs. We saw a variety of reasons companies hold inventory and these reasons dictate what is deemed to be an adequate supply of inventory. Now how do we balance this supply with its costs? First lets look at what kind of costs we are talking about. There are three types of costs that together constitute total inventory costs: holding costs set up costs and purchasing costs. Holding Costs. Holding costs also called carrying costs are the costs that result from maintaining the inventory. Inventory in excess of current demand frequently means that its holder must provide a place for its storage when not in use. This could range from a small storage area near the production line to a huge warehouse or distribution center. A storage facility requires personnel to move the inventory when needed and to keep track of what is stored and where it is stored. If the inventory is heavy or bulky forklifts may be necessary to move it around. Storage facilities also require heating cooling, lighting and water. The firm must pay taxes on the inventory and opportunity costs occur from the lost use of the funds that were spent on the inventory. Also obsolescence pilferage (theft) and shrinkage are problems. All of these things add cost to holding or carrying inventory. If the firm can determine the cost of holding one unit of inventory for one year (H) it can determine its annual holding cost by multiplying the cost of holding one unit by the average inventory held for a one year period. Average inventory can be computed by dividing the amount of goods that are ordered every time an order is placed (Q) by two. Thus average inventory is expressed asQ/2. Annual holding cost then can be expressed asH(Q/2). Set Up Cost Set up costs are the costs incurred from getting a machine ready to produce the desired good. In a manufacturing setting this would require the use of a skilled technician (a cost) who disassembles the tooling that is currently in use on the machine. The disassembled tooling is then taken to a tool room or tool shop for maintenance or possible repair (another cost). The technician then takes the currently needed tooling from the tool room (where it has been maintained another cost) and brings it to the machine in question. There the technician has to assemble the tooling on the machine in the manner required for the good to be produced (this is known as a set up). Then the technician has to calibrate the machine and probably will run a number of parts that will have to be scrapped (a cost) in order to get the machine correctly calibrated and running. All the while the machine has been idle and not producing any parts (opportunity cost). As one can see there is considerable cost involved in set up. If the firm purchases the part or raw material then an order cost rather than a set up cost is incurred. Ordering costs include the purchasing agents salary and travel entertainment budget administrative and secretarial support office space copiers and office supplies forms and documents long distance telephone bills and computer systems and support. Also some firms include the cost of shipping the purchased goods in the order cost. If the firm can determine the cost of one set up (S) or one order it can determine its annual setup order cost by multiplying the cost of one set up by the number of set ups made or orders placed annually. Suppose a firm has an annual demand (D) of 1,000 units. If the firm orders 100 units (Q) every time it places and order the firm will obviously place 10 orders per year (D/Q). Hence, annual set up order cost can be expressed asS (D/Q). Purchasing Cost Purchasing cost is simply the cost of the purchased item itself. If the firm purchases a part that goes into its finished product the firm can determine its annual purchasing cost by multiplying the cost of one purchased unit (P) by the number of finished products demanded in a year (D). Hence, purchasing cost is expressed asPD. Now total inventory cost can be expressed as: Total = Holding cost + Set-up/Order cost + Purchasing cost or Total =H(Q/2) +S(D/Q) +PD If holding costs and set-up costs were plotted as lines on a graph the point at which they intersect (that is the point at which they are equal) would indicate the lowest total inventory cost. Therefore if we want to minimize total inventory cost every time we place an order, we should order the quantity (Q) that corresponds to the point where the two values are equal. If we set the two costs equal and solve forQwe get: H(Q/2) =S(D/Q) Q= 2DS/H The quantity is known as the economic order quantity (EOQ). In order to minimize total inventory cost, the firm will order every time it places an order. For example, a firm with an annual demand of 12,000 units (at a purchase price of $25 each), annual holding cost of $10 per unit and an order cost of $150 per order (with orders placed once a month) could save $800 annually by utilizing the EOQ. First, we determine the total costs without using the EOQ method: Q= $10(1000/2) + $150(12,000/1000) + $25(12,000) = $306,800 Then we calculate EOQ: EOQ = 2(12,000)($150)/$10= 600 And we calculate total costs at the EOQ of 600: Q= $10(600/2) + $150(12,000/600) + $25(12,000) = $306,000 Finally, we subtract the total cost ofQfromQto determine the savings: $306,800 à ¢Ãƒâ€¹Ã¢â‚¬   306,000 = $800 Notice that if you remove purchasing cost from the equation the savings is still $800. We might assume this means that purchasing cost is not relevant to our order decision and can be eliminated from the equation. It must be noted that this is true only as long as no quantity discount exists. If a quantity discount is available the firm must determine whether the savings of the quantity discount are sufficient to offset the loss of the savings resulting from the use of the EOQ. There are a number of assumptions that must be made with the use of the EOQ. These include: Only one product is involved. Deterministic demand (demand is known with certainty). Constant demand (demand is stable through-out the year). No quantity discounts. Constant costs (no price increases or inflation) While these assumptions would seem to make EOQ irrelevant for use in a realistic situation it is relevant for items that have independent demand. This means that the demand for the item is not derived from the demand for something else usually a parent item for which the unit in question is a component. For example the demand for steering wheels would be derived from the demand for automobiles dependent demand but the demand for purses is not derived from anything else purses have independent demand. Other Lot Sizing Techniques There are a number of other lot sizing techniques available in addition to EOQ. These include the fixed order quantity fixed order interval model the single period model and part period balancing. Fixed Order Quantity Model EOQ is an example of the fixed order quantity model since the same quantity is ordered every time an order is placed. A firm might also use a fixed order quantity when it is captive to packaging situations. If you were to walk into an office supply store and ask to buy 22 paper clips chances are you would walk out with 100 paper clips. You were captive to the packaging requirements of paper clips i.e. they come 100 to a box and you cannot purchase a partial box. It works the same way for other purchasing situations. A supplier may package their goods in certain quantities so that their customers must buy that quantity or a multiple of that quantity. FIXED ORDER INTERVAL MODEL. The fixed order interval model is used when orders have to be placed at fixed time intervals such as weekly biweekly or monthly. The lot size is dependent upon how much inventory is needed from the time of order until the next order must be placed order cycle. This system requires periodic checks of inventory levels and is used by many retail firms such as drug stores and small grocery stores. SINGLE-PERIOD MODEL. The single period model is used in ordering perishables such as food and flowers and items with a limited life such as newspapers. Unsold or unused goods are not typically carried over from one period to another and there may even be some disposal costs involved. This model tries to balance the cost of lost customer goodwill and opportunity cost that is incurred from not having enough inventory with the cost of having excess inventory left at the end of a period. PART-PERIOD BALANCING. Part period balancing attempts to select the number of periods covered by the inventory order that will make total carrying costs as close as possible to the set up order cost. When a proper lot size has been determined utilizing one of the above techniques the reorder point or point at which an order should be placed can be determined by the rate of demand and the lead time. If safety stock is necessary it would be added to the reorder point quantity. Reorder point =Expected demand during lead time + Safety stock Thus an inventory item with a demand of 100 per month a two month lead time and a desired safety stock of two weeks would have reorder point of 250. In other words an order would be placed whenever the inventory level for that good reached 250 units. Reorder point =100/month ÃÆ'- 2 months + 2 weeks safety stock = 250 Other thoughts in Inventory Management There are a number of techniques and philosophies that view inventory management from different perspectives. MRP AND MRP II. MRP and MRP II are computer based resource management systems designed for items that have dependent demand. MRP and MRP II look at order quantities period by period and as such allow discrete ordering only what is currently needed. In this way inventory levels can be kept at a very low level a necessity for a complex item with dependent demand. JUST-IN-TIME (JIT). Just in time (JIT) is a philosophy that advocates the lowest possible levels of inventory. JIT espouses that firms need only keep inventory in the right quantity at the right time with the right quality. The ideal lot size for JIT is one even though one hears the term zero inventory used. Theory of Constraints Theory of constraints (TOC) is a philosophy which emphasizes that all management actions should center about the firms constraints. While it agrees with JIT that inventory should be at the lowest level possible in most instances it advocates that there be some buffer inventory around any capacity constraint e.g. the slowest machine and before finished goods. Future of Inventory Management The advent through altruism or legislation of environmental management has added a new dimension to inventory management reverse supply chain logistics. Environmental management has expanded the number of inventory types that firms have to coordinate. In addition to raw materials work in process finished goods and MRO goods firms now have to deal with post consumer items such as scrap returned goods reusable or recyclable containers and any number of items that require repair reuse recycling or secondary use in another product. Retailers have the same type problems dealing with inventory that has been returned due to defective material or manufacture poor fit finish or color or outright I changed my mind responses from customers. Finally supply chain management has had a considerable impact on inventory management. Instead of managing ones inventory to maximize profit and minimize cost for the individual firm todays firm has to make inventory decisions that benefit the entire supply chain.
