Outsourcing-harm to america Annotated Bibliography

Outsourcing-harm to america - Annotated Bibliography Example Outsourcing has been in practice since the early 1980s and continues to grow among large American corporations. Not only have we seen that it hurts our economy, but is affecting the unemployment rate. The unemployment rate is averaging 9.3% in todays market, compared to 5.8% in 2008 and 4.6% in 2007. Since 1986 fifteen million high paying jobs have left the United States and American workers. â€Å"Some industry watchers believe as many as 200,000 service jobs could be lost each year for the next eleven years (Cook, Nyham). According to the data (1999-2009) given by the bureau of labor statistics, United States -- there has been an increase in job loss in the private sector in the last 10 years ("Bureau of labor," 2010). Corporate America is sending jobs oversees so that their companies can save money, not thinking of the impact it has on us as individuals, and our families. Outsourcing is a chain reaction; the more products we outsource, the more factories that are being shut down in American, meaning more American job loss, and the rise of the unemployment rate Jobs are disappearing, wages are falling below inflation, and it is stressful in the workplace because at any moment ones job could be moved. overseas. It is killing American workers faith in their employers and putting a toll on their psychological well-being. We as a nation need to stop buying imported goods, and stop voting on bills that deregulate outsourcing. We need to realize we are the power, and we can make a difference. That in turn will be a step in the right direction. It is well known that United States economy recovered from mild recession in 2001; however, unemployment has risen from 4 % to 6% -- almost 50 percent increase. Well, one thing that is not known widely is that jobs have also been created during this hard period not only in New York City, San Francisco or Michigan – jobs have also been

Starbucks - Case Study Example | Topics and Well Written Essays - 500 words

Starbucks - - Case Study Example Additionally, the paper will describe the role of sustainable development in Starbuck’s approach to social responsibility. The Starbuck 2003 Corporate Social Responsibility Report, Titled â€Å"Living Our Values,† defines the coffee retailer’s approach to social responsibility. The approach focuses on partners, diversity, coffee product, customers, community and environment, and profitability. The three concepts of social responsibility are profit responsibility, stakeholder responsibility, and societal responsibility (Kerin et al, 2010). In relation to profit responsibility, a company should maximize profits for the stakeholders without taking advantage of supply shortages to charge very high prices on products. Starbuck’s observes profit responsibility by selling its product via supermarkets, the company’s retail shops, and by extension taking the Starbuck’s coffee experience to the employer’s offices. It uses low profit grocery market segments, retail business cafes, coffee kiosks, high profit margin kiosks, and corporate cafeterias to reinforce and serve its products using high-class experience. It embraces supplier diversity, pays its coffee suppliers well, and conserves their environment. These measures guarantees high and well deserved profits. Where, profits are significant for the growth of Starbuck’s, profitability is placed last as it depends on adherence to partners, diversity, coffee/product, customers, community and environment principles. In relation to stakeholder’s responsibility, a company focuses on stakeholders that can contribute to the achievement of its objectives. Indeed, the coffee retail shop encourages its partners, to stick to the mission statement, comment on deviations from Starbuck 2003 Corporate Social Responsibility Report, participate, and analyze management decisions. In addition, Starbuck’s accords

The Transatlantic Tunnel Of Transport Systems Information Technology Essay

The Transatlantic Tunnel Of Transport Systems Information Technology Essay For quite some time since the Industrial Revolution, sustainable transport has almost been synonymous with train form of transport. Several modifications have taken place on the first steam engine design to more energy and speed efficient models. With advancement in technology in this information and technology age, even more fascinating models are likely to be designed to keep up with the pace of lifestyle change. Critical limitations that hinder train transport systems will be addressed such as the geographical intricacies [1]. The Transatlantic Tunnel proposal dares to defy the ocean waters and the huge distance from America to Europe by bringing these two world business centers closer via a train. Top speed underwater tunnel across the Atlantic Ocean could be nearer to reality than many people would have thought. Engineering designers initially estimated that by the turn of the 21st Century, trains moving at around 5000 miles per hour could make the journey from America to Europe in less than an hour. Even though this future engineering project seems interesting, several issues need to be taken into consideration like the design that will pass the test of time across the treacherous ocean to the huge funding demand. Regardless of the factors standing in the way of the project, it remains a brilliant engineering project of this age. On the other hand, resilience could be propelled by the invaluable benefits that the project is likely to present to the world such that the project sees the light of the century. According to the documentary video Extreme Engineering, the possibility of this unbelievable project is not out of reach of reality amid modern technology. Challenged by t he success of the English Channel linking England with France, such ideas of completing the project cannot be unimaginable in this technological age. These are among the issues that this study explores, in an attempt to unravel this massive project. 1.2 The Main Text 1.2.1 Background Information. Nowadays, improvement of transport takes on a commercial perspective. Business had to be facilitated across nations in an efficient manner before using finer railway networks. In a more advanced version of the same networking, railway transport will now be explored for possibilities of connecting continents that are hundreds of miles apart. Building on past experience of connecting countries separated by seas and oceans, it is increasingly becoming a debate topic in engineering scenes on how continents can be linked by train for efficient transport. Similar ideas were illustrated in art and plays to demonstrate the relevance of the creation of such work [2]. 1.2.2 History and Theory. Jules Verne is the first visionary to suggest the Transatlantic Tunnel idea in 1895. The initial design could probably have been prompted by Vernes long and unpleasant sailing experiences [3]. Since there are several art works that used a fictional model of the Transatlantic Tunnel, its actualization was not taken seriously until real engineering work was brought on board. Suggestions have been made on several areas where the train and the tunnel system would need to overcome the most pressing missing links. Theories and ideas of a tunnel linking the said continents have been persistent and the best postulations were demonstrated in a film by the name Transatlantic Tunnel which was made in 1935 [4]. In the movie, a problematic development of the project featured an illustration of the difficulties that the project faces at the current stage. Most of the early positions held on the same topic were based on a fictional tunnel that was operational, perhaps to illustrate the applicability of the project. An earlier version of the same proposal had been developed and captured in the year 1933, in the German movie Der Tunnel [5]. By 1945, trains that used the vacuum principle to achieve speeds of over 1000 meters per hour were already in place, thanks to pioneers of real engineering studies. One of the major engineering pioneers of such designs was Robert Goddad who devoted much of his energy to similar engineering research. Three decades later, engineering articles that widely advocated for adoption of the technology were circulating. Vacuum train attention changed in the 80s after discovery of the Japanese Maglev research [6]. Transatlantic Tunnel theory bases its postulates on the past engineering works where transport lines have been suspended in water. According to the Discovery Channel, the English Channel links England to France in an almost similar way that popular transatlantic models envision [7]. Current top speed train formats are designed on magnetism and vacuum principles to enhance efficiency in terms of speed and resistance. Such trains models came into existence in the year 2004 when Shanghai. Famous progress towards the realization of the project was made through the contribution made by Frak Davidson, who carried out similar research on the applicability of such a project. Assisted by another prominent engineering designer by the name Earnst Frankel, Davidson had made some of the most promising contributions to the project. In his earlier engineering projects, Davidson had participated in the study operations of a fact-finding group of the possibility of setting up a tunnel underneath the English Channel; the English Channel Tunnel. The school of thought that has been propagated for a possible Transatlantic Tunnel design mainly relies on the work of Davidson. He proposed a system that would apply a suspended tunnel that is about 300 feet into the ocean. Another postulate of his design is the anchorage in deep sea where tethering is used to connect the tunnel to the anchor. Besides, he had also postulated that a vacuum would be necessary in his design, to facilitate top speed for the train. Finally, he also envisioned a magnetic train system being introduced into the same system for stability and speed enhancement [8]. 1.2.3 Design Approach Vacuum trains have been used in many high speed models that have been able to achieve extraordinary efficiency. To achieve the fastest speed that suits the model of train inside the tube-like tunnel, evacuation of the air that is inside the tube is usually necessary. This leads to the creation of an air free column which is capable of achieving speed similar to that achieved by a falling object in air. Bearing in mind that the project traverses across the entire Atlantic Ocean, time would be a significant aspect for any useful and efficient transport system. The best solutions so far generated by the engineering fraternity have largely relied on the vacuum train model which delivers results for top speed [9]. Magnetic Levitation system of transportation that uses magnetic force to propel locomotives has also been added into the design. Also referred to as maglev trains, the trains so propelled using magnetic field rely on three important components namely; source of electric energy, metal coils and large magnets. There are several advantages that the Maglev system presents to the design, including speed and stability. In this model, trains are lifted from ground level and are functioned on the principle of electromagnetism. According to Sirohiwala, Tandon and Vysetty, two main principles of engineering are exploited by the system, namely; Electromagnetic Suspension which relies on attraction forces as well as Electrodynamic Suspension which uses repulsion forces [10]. A combination of the vacuum and magnetic levitation systems have also been explored and found out to give better results. The benefits of a magnetic system coupled to the vacuum system will deliver not only top speed but also stability in the tunnel transport. According to the research conducted by the Massachusetts Institute of Technology, non contact bearings that magnetic levitation trains apply facilitate the realization of very high speeds and in conditions such as those present in vacuum train designs [11]. Also, utilization of both systems in a high speed train system facilitates the elimination of frictional force which generally causes wear and tear. This implies that a hybrid system of the two systems could offer more benefits in cost reduction than most other systems. Currently, the design that could be applied for the project heavily borrows from the engineers who postulated a similar design called Channel Tunnel that could run under the English Channel [12]. Suspension design is preferred by engineers, where surface turbulence and the underground uncertainties are handled. Joining of pontoons will be carried out at a distance of about 50 meters below the water surface. To hold the huge pontoons in place, heavy sea anchors will be dipped to the floor of the sea and tethers used to connect the two. By so doing, several challenges will be overcome, including deep sea pressure, surface collision with ships as well as heavy waves. This distance is safe also for possible rescue operation, in case there is an emergency in the tunnel. A cylindrical design has been adopted by the design since cylinders have inherent strength against wave forces, by reducing reactive resistance. The heavy pontoons that house the train are postulated to have a thick casing that is cylindrical in shape. A special vessel will transport the pontoons to the sea and facilitate their submersion as well as connection to the extended tunnel using special fastening screws and adjoining. Tethering will then be done onto an immersed anchor that sits deep into the sea floor. A continued extension of the tube will facilitate the completion of the tunnel from America to Europe. 1.2.4 Alternative Designs Besides the suspension design that is currently advocated for by many engineers, there were two other designs that were postulated for the same. The first postulated tunnel type was in the form of a seabed drilling process that characterized traditional tunnel construction. On an account of the involved difficulties, this proposal was later rejected. These difficulties included the huge depths of the Atlantic Ocean at some points as well as the presence of submarine mountains. In addition, major earthquake prone regions posed a threat to the successful traversing of the tunnel. In earlier versions of the tunnel design, a different approach was envisioned by constructing the transatlantic tunnel on the surface and eventually submerging it into the bottom of the ocean. This design was likewise rejected on intricacies that revolve around hydrodynamics in a huge water body such as the Atlantic Ocean. Pressure of the huge water column possessed by the Atlantic Ocean was identified as a threat to the form of structure to be submerged. It is alleged that the materials proposed for use by the tunnel cannot withstand the huge pressure exerted at the bottom of the sea. Besides, human beings cannot perform the construction functions at the bottom of the sea due to the high pressure. Any rescue operation in case of an emergency would almost certainly be in futility since the destructive nature of the pressure could be hazardous even to the rescue teams. 1.2.5 The Project Several issues are involved in the design of an appropriate system that is able to overcome the challenges expected in the Atlantic Ocean. By making some of the most difficult decisions regarding the safety risks and costs incurred, engineers are determined to deliver a suitable Transatlantic Tunnel. The most disturbing questions that the engineers have had to solve regarding the project touch on the route, source of money, resistance, risks as well as the benefits. This section of the report discusses some of these underlying intricacies that designers have been compelled to solve. 1.2.5.1 Route Several routes were considered for various reasons, but one route is particularly preferred for the same. In order to ensure that the tunnel traverses the huge distance form America to Europe in less than hour, several factors are considered to arrive at the preferred route. Cost and safety are among the most important considerations made by designers. Whereas a straight and direct route could be shorter and economical for the project, safety considerations could prop up due to the earthquake activity along the straight route. The risks involved in the project must be closely quantified to ensure that the massive investment made does not get compromised deep into the actualization [13]. According to Sirohiwala, Tandon and Vysetty, the most applicable route that the project will consider is the route that avoids some challenging geographical conditions in the Atlantic Ocean. Following well researched calculations of distance and appropriate route, engineers have been able to find out the route that passes through Iceland and some parts in south Greenland from London then reach New York from the North Eastern side to be suitable [14]. Despite extra costs being incurred for the drilling of the land sections in the connecting regions in the north, this route design has been able to overcome adverse results likely to be encountered in the deep ocean regions with earthquake activity. Besides, extreme weather conditions found in the northern hemisphere around Iceland and Greenland pose a challenge to the continuity of the project in the regions. However threatening this proposed route appears in terms of extreme temperatures to the north as well as drilling necessity, the corresponding challenges of the alternative route are also considered. In view of the challenges encountered by avoiding this route, earthquakes are much more of a risk when taken in comparison. Unexpected destruction to the system poses as a more serious and potent threat to the project than the former mentioned risks. In addition to destruction, deep ocean pressure factors also cause a huge setback to the implementation of the project. When considered in comparison, drilling and harsh weather factors encountered in the preferred route are less potent costs than what would be needed to counter the high pressure in deep sea. It is projected that the pressure exerted by the water column at deep sea could cause serious trouble to the integrity of the system. The cost likely to be incurred for such materials that can withstand the huge pressure as well as carry out the construction works that deep is very high. Maintenance could consequently be expected to carry a very huge cost element and risk when compared to the drilling procedure. 1.2.5.2 Air Resistance Train transport faces some resistance from the air, just like several other forms of transport. In top speed models, a streamlined front end has been adopted in design to overcome the resistance. The introduction of the vacuum considerably reduces the drag. The design of the tunnel must also be responsive to avoid natural drag designs. Aerodynamic drag is particularly common inside a tunnel than it is outside a tunnel. Aerodynamic drag is experienced accompanied by pressure waves that travel as fast as sound and gets altered as the train gets introduced into the tunnel, changes its velocity as well as when cross-sectional aspects of the tunnel get changed too. Fluctuations in pressure penetrate the train where aural discomfort is experienced by the passengers. Generally, confinement of the environment around the train causes changes in the aerodynamic system of the tunnel. At the thin end of the tunnel, the amount of pressure changes is determined by how long the tunnel and the train are as well as by the entry time taken before a second train enters the tunnel. To determine the amplitudes of the aerodynamic pressure variations involved, speed, nose geometry as well as blockage ratio are used. Bearing in mind that the Transatlantic Tunnel is a very long Tunnel, it is predictable that a maglev system will contribute very large amounts of pressure variations and possible discomfort. Aerodynamic drag is also characterized by the directly proportional relationship it has with power consumption. Air resistance is usually reduced by about eight times with a reduction of velocity by half. This means that the power consumption varies with proportion to speeds cube. In view of the other factors involved in resistance, size and shape of the head with regard to the degree of streamlined nature also determine power consumed. It is therefore a common design across train models proposed for the Transatlantic Tunnel having a streamlined shape. There is a general challenge posed by aerodynamics of a top speed train that uses a tunnel. The flow of the air at the exit of the tunnel is usually at a very high velocity that is about ten times more than the ordinary requirement of a smooth ride [15]. 1.2.5.3 Investment (Funding Parties) Apparently, the issue of funding and the most important partners has not been at a critical and determinative stage. Project enhancement proposals have only been circulating without a mention of how the funds could be secured: However, by the look of the benefits that the two main continents and the entire world stand to gain in case of a successful implementation, funding should be forthcoming. Perhaps what is needed is a strongly convincing organized lobby platform to ensure that stakeholders are brought on board. States incidental to the project are however expected to play a key role in the overall funding requirements of the project. This implies that the US, Canada and Britain have a more direct funding role to make for the project than any other state. Direct benefits expected from the use of the tunnel are likely to compel these states to make the investment in anticipation of the same. However, their willingness and therefore the prospects of the realization of the project will depend on the level of their satisfaction that the engineering work done delivers. It is expected that the investment opportunity that the project avails could attract attention of a regional funding due to the creation of the trading blocks that have characterized continents such as the EU. The EU is largely an economic block that taps into unexplored opportunities on behalf of the member states and such a lucrative project could have direct funding from the block. However, just as individual states would demand the ascertaining of certain project reliability score, the EU could also work on assessments to ensure sustainability of the project. The ball goes back to the engineering field to carry out as much research and development studies as would constitute an irresistible offer for funding during lobbying for funds. Alternatively, private sector investment and funding for the project cannot be left out. With evidence of some major investments being solely undertaken by the private sector, the possibility of contributions into this project cannot be ruled out. Commercial activities that the private sector will anticipate to achieve upon completion of the project will spur interest which is consequently likely to avail funding. Development partners of the involved states are likewise in the list of likely funding source based on commercial benefits that they would obtain from the project. 1.2.5.4 Challenges and Dangers Ocean currents are one of the challenges that the tunnel would have to be prepared to withstand. Across the Atlantic Ocean, very strong current waves exist for instance the Gulf Stream. Structural oscillation design will need to be very strong such that the tethering system adopted will take care of the swaying motion of the storm. Relating the suspended tunnel to suspension bridges, motion occasioned by wind and water has been found out to be catastrophic. Major suspension bridges such as the Tacoma Narrows Bridge have been brought down by strong winds and a similar phenomenon can be expected from strong ocean currents for a suspension tunnel. Suspending the tunnel in water will necessitate the use of deep sea anchors that will ensure firm tethering. Bearing in mind the depth of the ocean occasionally goes to nearly five miles, the possibility of achieving firm tethering into the sea appears evasive or a cumbersome design. Besides the technical requirements that the project will need to facilitate anchorage to such depths, the materials quantity and quality that can facilitate this project are almost unimaginable. In view of the distance and possible design consumption, it is estimated that around one billion metric tons of steel will be needed. In addition, the ocean floor where the tunnel will traverse is almost certain to encounter some region of earthquake vulnerability. In view of the hazardous effects of earthquakes to engineering projects, the inevitable encounter with such factors make the project one of those marred with uncertainty and challenging circumstances. In addition to exposure to earthquake challenges, the geography of the ocean floor through which the tunnel will traverse presents daunting route choice technicalities. Despite there being several options of possible routes that the tunnel can pass, each of the options has its unique set of challenges such as the most economical distance. About 3,000 miles of distance across the ocean stand in the way of the projects success. The long distance from North America to Europe will require consideration of the most applicable route and what point of initiation or termination to design the project. Besides the issue of the route, the project demands a massive construction material that requires the world supply. For instance, from the beginning to the end of the project, available world steel production capacity will be highly beleaguered. Whether the needed materials demand will be estimated and stored in such reserves as would be capable of sustaining the project remains a strategic oper ation challenge. The continuity of the project will face several challenges among which weather will appear to impact heavily. In the recent weather patterns, severe winters have been experienced in Europe and North America and across the Atlantic Ocean. Temperatures way below the freezing point will certainly affect the rate of project progress during winters. Together with the distance complexities, other factors such time will therefore act as an impediment to the projects desire to be expeditious. Estimates of the duration of time needed to complete this project stand at a staggering one century or more. High speed trains designated for the tunnel transport require very high levels of stability. To achieve very high stability as required could pose as a threat since very little breaches could severely damage the system. Most faults in an engineering project depend on the level of stability flaws. Besides the anchor and tether system that the tunnel design adopts, speed inside the tunnel needs to be enhanced for better stability. One of the proposed ways to achieve top speed for the train is through the creation of a vacuum. To achieve a vacuum over a relatively shorter distance has proven to be an uphill task for engineers; how to achieve this over a large distance such as from America to Europe is even unimaginable. How to achieve top speed for stability purposes appears to pose the most potent challenge. 1.2.5.5 Advantages a) Energy Tunnels Maglev systems are environment friendly and highly save on energy due to electrical energy consumption .The system appears to be shielded from the controversial oil energy sources of energy. Usage of nuclear energy will not only save money but spaces utilized for fuel carriage. b) Maintenance Ordinary railway and road transport particularly experience heavy wear and tear costs which are not encountered in maglev systems. Basing maintenance costs on wear and tear occasioned by contact, it will be less expensive to maintain a system where no contact is experienced. c) Speed Among the most striking features of the proposed train model, speed is by far the best. These train models can achieve speeds of up to 500 kilometers per hour. Business will be enhanced between Europe and America to supplement to the sea and air transport systems. d) Weather While compared to several other modes of transport, tunnel train transport tackles unfavorable weather in a dramatic way. Inside the tunnel, weather based hindrances to operations of the train are not expected. Poor weather conditions such as visibility and snow cannot affect the flow of the train at its top speed. e) Cost of Operation Since train transport is generally cheaper when compared to some other modes of transportation, costs of operation are considerably expected to reduce from America to Europe. This is so despite the capital initialization of the project which might be higher than any other project done before. f) Capacity Trains have a higher load capacity than many other modes of transport, including air transport. Achieving a supersonic train model would by far outdo major huge aircraft models such as the Concorde, which is not operational today due to several factors [16]. 1.2.5.6 Disadvantages a) Time. Proposals might be very appealing to the eye but the amount of time required for the completion of the project act as a major hindrance. It is estimated that over at least a century lies between the proposal and the actual implementation of the project. b) Distance To construct and transport materials from the mainland to the construction site may prove to be an onerous task for the engineers. Distance for movement of labor and materials will act in hindrance to the projects implementation. c) Cost Despite the relatively lower cost of production, there is a high certainty that the project will be the highest in history of engineering works. It is estimated that labor, materials and other logistic costs will need more than one financier for the project. According to a similar project study carried out by the Norwegians, cost was the only hindrance [17]. d) Construction Conditions Construction across the large Atlantic Ocean will have to face serious weather challenges including freezing temperatures as well as strong winds and currents. The most appropriate route will have to be chosen to overcome this challenge, which may appear to be expensive. Deep sea construction of the tunnel will be faced with high pressure that demands for specialized machinery instead of human beings. e) Geography As mentioned before, geographic issues will be encountered by the construction of the tunnel, demanding drilling to supplement to the suspended model. Drilling will be necessitated by over-land sections encountered in the cheapest route choice. This will not only affect the pace of construction but also change the design of the train. f) Emergency and Rescue In case of adverse hitches in the operation of the top speed train, it will be impossible to perform a rescue operation. Other transport systems are easily accessible for rescue operations than in sea transport, worst scenario being a submerged system such as a suspension tunnel. g) Risk Uncertainty As it is currently with major civil engineering works, measurement of risk involves several issues, with some having collapsed more than once. Collapsing of such a massive construction could not be ruled out completely, bearing in mind the existence of several hindrances to the system. h) Passenger Comfort Sudden acceleration and deceleration leaves an unpleasant feeling in the body of the passengers. Since the Transatlantic Tunnel is designed on a very high speed platform, sudden acceleration changes will be expected to be an unpleasant experience for the customers, unless more time is allowed to facilitate adaptation of the body. 1.2.6 Project Feasibility Checking is likely to feature the feasibility aspects of the project, technology, economics, law, operation and schedule. Whereas relevant technology is likely to be within reach for such a project, clearly outlined requirements of the project are yet to be prepared. Maybe by the time the project reaches critical stages of implementation, such details will be availed. In the current information and technology age, anything is virtually possible since all the relevant information is within reach [18]. In terms of economics, it can be said that the possibility of the project reaching a successful end is quite remote. Legal frameworks are not a major hindrance since similar projects have taken place but at a lower magnitude. Operational feasibility is likewise uncertain, having several loopholes in the coordination of the research as well as funding intricacies involved. With regard to schedule, the project is unfeasible as it is, since time expected for completion is over a century. Within the span of such duration of time, several options would have propped up making the project obliterated and unnecessary. Efficiency of the project is also uncertain due to the challenges expected ahead. Whether there is a need for such a project is a question that could be argued favorably or not. However, as it currently stands, it is needless to embark on the project. Conclusion Transatlantic Tunnel will remain to be one of the greatest civil engineering ideas of the human history. Despite the challenges that the project presents to engineering designers, it can be done, but at a very high cost. The speed of the train could challenge investors to quicken implementation since the benefits of the project will proportionately flow speedily. No matter how interesting the project seems, time factor and cost act as the major hindrances to its implementation.

Psychiatric Side Effects Hormonal Contraceptives Health And Social Care Essay

Current scientific literature widely supports the fact that estrogen and Lipo-Lutin have some effects on the cardinal nervous system, but adult females have ever understood that they feel otherwise depending on what portion of their hormonal rhythm they are on. Womans are rather familiar with the psychological and emotional hurt caused by premenstrual syndrome. Family members can place with the noticeable behavioural alteration from pre to post-puberty females due to the addition of sex endocrines within the organic structure. It so follows that the inquiry of what, besides the primary effects of sex endocrines, estrogen and Lipo-Lutin are making in the organic structure to arouse such behavior-altering phenomena? To adult females, it is clear that endocrine degrees are changing the manner we think and feel, yet many hormonal preventives fail to name important temper and behavioural alterations as a side consequence. In fact, one article by Douma et Al. ( 2005 ) states that despite p resenting alterations in absolute and comparative degrees of estrogen and Lipo-Lutin, emotional and sexual side effects of unwritten preventives are mostly ignored in the research literature. If these endocrines do in fact map as behavioural and psychological qualifiers, are at that place unsought effects of consuming hormonal preventives that can greatly change temper and behaviour? This is an effort to reply, through a reappraisal of the literature on the interactions between endocrines and temper upsets, if the side effects associated with hormonal preventives are excessively great of a hazard to female outlook to be taken.Female Generative Cycle:After making sexual adulthood, a adult female will travel through the generative rhythm until making climacteric, the point at which she will no longer be able to hold kids. Womans have monthly two generative rhythms that are tightly linked by hormonal ordinance. During adult females ‘s rhythms, the organic structure prepares for f ertilisation of the egg, which is released about halfway through the rhythm. If the egg is non fertilized after being released, menses occurs and the rhythm repeats itself. Ultimately, control of the generative rhythm belongs to the encephalon. The ovarian rhythm includes all of the alterations that happen in the ovaries while a adult female remains fertile. First, gonadotrophin let go ofing endocrine ( GnRH ) is dispensed from the hypothalamus through the intermediate hypophyseal portal system, exciting the anterior pituitary to release both follicle exciting endocrine ( FSH ) and luteinizing endocrine ( LH ) into the blood stream. When the endocrines reach the sex glands, they bind to receptors on the ovaries and originate a concatenation of events that begin follicular growing, a procedure that will bring forth an egg as the female gamete. As the follicle grows within the ovary, it begins to let go of estradiol at low degrees, which maps in the uterine rhythm and besides inhibits the release of more FSH and LH from the pituitary. As the follicle nears ripening, estradiol degrees rise steeply. The high concentration of estradiol plants opposite how low estradiol concentrations in the organic structure map, exciting the hy pothalamus to release GnRH and doing a rush in both FSH and LH. The rush in LH allows the follicle to make adulthood, and ovulation by and large occurs about a twenty-four hours subsequently. The follicular tissue remains in the ovary and is transformed into a impermanent secretory organ known as the principal luteum in response to LH. The principal luteum secretes the endocrines estradiol and Lipo-Lutin, which exhibit negative feedback on the encephalon to diminish FSH and LH degrees. As these degrees get really low, the principal luteum disintegrates, the negative feedback rhythm is disrupted, and the rhythm starts over once more ( Cambell et al. , 2008. ) The uterine rhythm begins with the thickener of the liner of the womb in readying for the possible nidation of an embryo. This occurs in response to estradiol being secreted from follicles within the ovary. After ovulation, Lipo-Lutin and estradiol work in concurrence to turn endometrial secretory organs in the womb and increase blood supply to the endometrium while go oning to increase the thickness of the uterine liner. If an egg is non fertilized before it passes out of the female, the principal luteum will devolve. The bead in ovarian endocrines causes the blood vass of the endometrium to compress and starves the uterine liner, ensuing in menstruations ( Cambell et al. , 2008. )Hormonal Contraceptives:Pregnancy is a long-run committedness that is energetically expensive to the female and requires life manner alterations to care for the offspring until they are able to care for themselves. For these and other personal grounds, ways to forestall gestation have been developed to let a twosome to make up one's mind when they are ready to hold a kid. Of class, abstention and male barrier methods are available, but to guarantee a greater grade of protection in intercourse the female may take to utilize hormonal preventives to change the organic structure ‘s rhythmic rhythms that prepare for gestation. Effective and reversible, many adult females today choose a hormonal birth control for greater independency in life. How frequently the hormonal preventive demands to be taken depends on the method of pick and type of endocrine. There is a battalion of different types of hormonal contraceptive method available that a female can take from to forestall gestation which involves legion methods of bringing and types of endocrine. Common manners of bringing include an ingestible tablet signifier, a skin spot placed at assorted locations on the organic structure, a ring placed inside of the vagina, and hormonal injections given in the clinic. The endocrines these pre ventives contain are most normally the endocrines produced by the ovary. Hormonal preventives map in a assortment of different ways to forestall gestation. To understand how they work, it is of import to understand how ovarian endocrines map in the organic structure of course. In general, most steroid endocrines are transcription regulators. Steroid endocrines are produced by changing the substrate cholesterin and act on a broad assortment of tissues. As antecedently discussed, the ovaries produce two endocrines rhythmically, estradiol and Lipo-Lutin. Hormonal preventives consist of progestogen, a man-made, progesterone-like endocrine that can be given entirely or in concurrence with man-made estrogen. Hormonal contraceptive method contains man-made derived functions of estrogen and Lipo-Lutin in combination or by themselves. Most unwritten preventives work by forestalling contraceptive method, but some alter the endometrium to forestall nidation of the embryo. Combined preventives work through negative feedback to the hypothalamus, stamp downing GnRH and therefore FSH and LH secernments. Without the rush of LH/FSH degrees, the follicle will non finish development, impeding the production and release of a secondary oocyte. Other contraceptive method methods known as consecutive readyings prescribe estrogens for some period of clip and so Lipo-Lutin, following the normal rhythmic sequence of the organic structure ‘s rhythm. Progesterone is besides given entirely and exhibits negative feedback on the release of LH, which can change the organic structure to the point where it acts as if it is pregnant, impeding the release of any other eggs ( Hadley, M. , Levine, J. , 2006. ) Progesterone is synthesized as a precursor to both of the other sex endocrines, androgens and estrogens, in the thecal cells that form the follicle. However, merely little sums of Lipo-Lutin are produced in this manner – most of the Lipo-Lutin in the organic structure is manufactured by granulosa cells of the principal luteum. In several stairss, cholesterin is oxidized to pregnenolone, which is once more oxidised and undergoes keto/enol tautomerization to organize Lipo-Lutin. Progesterone is the endocrine responsible for fixing the organic structure for gestation and keeping the embryo one time a adult female becomes pregnant by exciting growing and development of the womb and Fallopian tubes. Progesterone exhibits control on the secernment of GnRH and gonadotropin secernment ( Hadley, M. , Levine, J. , 2006. ) Estradiol is produced in the ovaries in response to follicular growing following the release of the pituitary endocrines LH and FSH. The complete synthesis of estradiol occurs within the follicle of the ovary. First, a multistep mechanism converts cholesterin, which is obtained from the consumption of fatty acids, to the intermediate androgen androstenedione. Some androstenedione is converted to testosterone, which is enzymatically oxidized by aromatase for the transition to active sex endocrine estradiol. When estrogen starts being produced at high degrees in the female following pubescence, it is responsible for the ripening of the female sex variety meats, including the vagina, ovaries, womb, and Fallopian tubes. In these countries it causes tissue growing and development, increased blood flow, mucus secernment, prostaglandin synthesis, and increases the figure of Pitocin and estrogen receptors in the womb. Besides the sex variety meats, estrogens have an consequence on many other countries of the organic structure. Estrogen has several actions on the pituitary, including the followers: positive and negative feedback set uping the secernment of the FSH and LH ; increases the figure of GnRH receptors ; increases the production of Pitocin ; and increases the production of lactogenic hormone. To all of this, estrogen besides affects the cardinal nervous system, and it is possibly these effects that are most unreassuring when sing hormonal birth control. Behaviorally, the addition of sexual desires and maternal inherent aptitude alters libido ( Hadley, M. , Levine, J. , 2006. )Side Effectss of Hormonal Contraceptives:Physical, mental, and societal wellbeing are of import facets of a healthy life. Treatments are beset for physical manifestations of unwellness, but when it comes to psychiatric upsets solutions are much less abound. Many of these unwellnesss have a familial constituent in add-on to environmental factors, doing chances for successful intervention lo w due to the individualised nature of psychiatric upsets as a whole. Investigating possible causes for mental unwellness should however be a precedence for doctors. A consolidative feature of work forces and adult females that may be a promising path to some conditions impacting mental wellness prevarications in the sex endocrines, the biological indexs of birthrate and maturity. However, a big figure of psychiatric upsets affect adult females to a greater extent than work forces – while adult females are fertile, they produce estrogen and Lipo-Lutin in greater sums than their male opposite numbers. It is therefore possible that these steroid endocrines are lending to the addition of temper upsets in females. Hormones diffuse straight into the endothelial cells of the blood encephalon barrier and hold several well-documented maps on the hypothalamus and pituitary. In add-on to these countries, receptors for the sex steroids are found in other locations where emotion, knowledg e, and behaviour is regulated ( Westberg, L. , Eriksson, E. , 2007. ) The effects of decreased degrees of endocrines has been studied in conditions such as premenstrual dysphoric upset, perimenopausal dysphoria, postpartum depression, postpartum psychosis, dysphoria induced by unwritten preventives or hormonal replacing therapy and anabolic steroid-induced aggression ; correlativities may be between sex steroids and autism, depression, panic upsets, anxiousness upset, agoraphobia, transsexualism, dependence, and attention-deficit hyperactivity upset ( Westberg, L. , Eriksson, E. , 2007. ) The reappraisal paper by Westberg and Eriksson ( 2007 ) analyzed cistron polymorphisms of the sex steroids and their relation to psychiatric status, but clearly stated is the deduction that if cistron discrepancies are associated with a certain status, so it is likely that they influence the homeostasis of that peculiar variable. In surveies of the female life span, fluxes of estrogen can be linked to many behavioural upsets: while a female is fertile, estrogen degrees flux greatly during the luteal stage of the catamenial rhythm – this corresponds to premenstrual syndrome, which is experienced in most adult females undergoing menstruations ; after holding a kid, estrogen degrees bead, which could take to postpartum depression ; come ining climacteric, irregular rhythms cause big fluctuations in estrogen degrees, and many adult females cite experiencing depressed during this clip ; and eventually, during climacteric, estrogen degrees bead to extreme depressions from what the organic structure is used to, and diminution in many psychological provinces is exhibited ( Douma, S. , et Al. 2005. ) In add-on to its engagement in memory, concentration, and cognitive map, estrogen mediates several neurotransmitters in the encephalon that may play a function in temper – for illustration, the effects on se rotonergic map and Dopastat degrees may indicate towards a nexus with depression ( Douma, S. , et Al. 2005. ) A pilot survey on the relation of depression to hormonal preventives indicated that users of unwritten preventives may be more inclined to depression than non-users ( Kulkarni, et Al. 2005. ) In a double-blind survey by Grounds et al. , ( 1970 ) depression as a side consequence of hormonal preventives was found to be independent of antecedently bing symptoms. The survey concluded that depression was due to the hormonal chemicals in the preventives. Figure 1: Degree of Mood Change in Oral Contraceptive Users Compared to Placebo Several theories exist on the mechanisms for how the sex endocrines can be changing temper. Plausible explainations include an estrogen-induced vitamin B6 lack and subsequent lessening in 5-hydroxytryptamine and GABA degrees due to the low affinity of the decarboxylases for pyridoxal phosphate ; a Lipo-Lutin and estrogen mediated augmentation of GABA-induced suppression and suppression of glutamate excitement ; and a progesterone-mediated addition in monoamine oxidase activity ensuing in reduced concentrations of 5-hydroxytryptamine ( Oinonen, K. , Mazmanian, D. , 2001. ) Estradiol may impact Dopastat receptors, increase the release of Dopastat in the subcortical part of the prosencephalon, and diminish the consumption of Dopastat, all of which would increasing the length and badness of the consequence ( Vulink, et al. , 2006. ) Research suggests that this portion of the encephalon, the karyon accumbens, may work in pleasance, dependence, being happy or sad, and many other emotions ( Vulink, et al. , 2006. ) Harmonizing to an article by Parry and Rush ( 1979 ) , temper alterations, in peculiar depression, have been found to be correlated to the length of unwritten contraceptive method usage, the concentration of Lipo-Lutin, and a familial sensitivity to the disease. Although it may hold some kind of environmental constituent, surveies have demonstrated that depression may develop due to lessenings in the degree of monoamine neurotransmitters found in the encephalon, notably 5-hydroxytryptamine and noradrenaline. Hormonal contraceptive method may be making this instability by impacting the production and debasement of 5-hydroxytryptamine and noradrenaline. Serotonin is created in a mechanism of several stairss that hydroxylizes and so decarboxylates the amino acid tryptophan. Oral preventives may heighten tryptophan metamorphosis and act as a competitory inhibitor of vitamin B6 phosphate, both of which decrease the handiness of tryptophan for the production of 5-hydroxytryptamine. Other s urveies confirm that tryptophan may be metabolized at an increased rate in users of unwritten preventives ( Shaarawy, et al.,1982. ) Noradrenaline is synthesized through a series of stairss that convert tyrosine to L-dopa and Dopastat, which is oxidized to make the terminal merchandise. Pyridoxal phosphate is used to catalyse the reaction of L-dopa to dopamine, a procedure which is inhibited through the usage of hormonal preventives. Besides, preventives may diminish plasma tyrosine degrees, take downing the handiness of the precursor to norepinephrine, and increase monoamine oxidase, an enzyme that destroys noradrenaline after it is created. Changes that occur to the encephalon under the influence of steroid endocrines can be observed through the usage of EEGs. The correspondence of electrical activity with altering endocrine degrees is clear indicant that Lipo-Lutin and estrogen map in the encephalon ( Becker, et al. , 1982. ) Estrogen receptors have been found in the hypothalamus, though there is still much to be elucidated on the location and distribution of Lipo-Lutin receptors ( Becker, et Al. 1982. ) Women taken hormonal preventives have been observed to hold a decreased alpha beat on such surveies ( Parry, Rush, 1979. ) These consequences may assist find how psychological abnormalcies develop after consuming steroid endocrines. Hormonal preventives have been implicated in impacting the badness of obsessive-compulsive upset. In a survey by Vulink, et Al. ( 2006 ) it was found that unwritten preventives could overstate or better the symptoms associated with this mental unwellness. The survey goes on to propose that ground for this alteration might hold to make with the consequence of endocrines on the map of Dopastat in the encephalon. Since OCD might besides be affected by Dopastat, this is cause for concern. Datas on temper alterations can be hard to quantify, doing the undertaking of placing a questionable nexus between hormonal preventives and mental upsets complex. In add-on, variables between persons can do the state of affairs even more upsetting. For illustration, it is possible that a sensitivity to mental unwellness contributes to negative temper alteration experienced with hormonal preventives. Some preliminary work on this many-sided undertaking suggests that the correlativity between negative temper alterations and hormonal preventives may be affected by the temporal form of dose more than their components and ratio ( Oinonen, K. , Mazmanian, D. , 2001, ) yet others province that the relationship may be more luxuriant, and likely justly so ( Douma, S. , Al. 2005. ) To clear up the input of familial versus drug-induced psychiatric upsets, we can look to information from a twin survey. Kendler, et Al. ( 1988 ) performed a survey on 1131 twins to place which side effects of unwri tten preventives may be related to genetic sciences and which effects are related to consumption of the drug. Consequences from this survey supported a familial influence over the psychiatric side consequence of depression if it is related to the physical side effects of weight addition and hydrops, which were clearly influenced by familial factors. The consequences besides suggested that familial factors may hold an of import function in crossness. However, a multivariate analysis in the same survey suggests that these psychiatric symptoms were independent of both the physical side effects of unwritten preventives and symptoms of built-in psychiatric upsets. The survey concluded that although cistrons have been definitively demonstrated to act upon depression, psychiatric symptoms and a antecedently bing sensitivity to mental unwellness appear to be comparatively independent. Another decision of this survey stated that the environment did non look to hold an consequence on psychiat ric symptoms reported by the users of unwritten preventives. Although the survey has some mistakes to be taken into consideration, such as self-reporting symptoms by topics and merely detecting twins whom volunteered, this grounds suggests that hormonal contraceptive method may hold a direct function in bring oning assorted psychiatric upsets as a side consequence of forestalling gestation.Decision:Most medicative drugs have some kind of side consequence that is by and large unpleasant but deserving taking for the curative consequence it was prescribed for. Birth control is more of an optional medicine than many prescription drugs, but is still taken by many adult females in America and around the universe. It can be hard to restrict a medical specialty to a individual curative consequence when the chemical occurs of course in our organic structures and affects many facets of homeostasis, though when side effects change from being inconvenient or somewhat straitening to something th at can impact mundane behaviour and temper, concern for what is being put into our organic structures becomes elevated. Even with the possibility of temper alterations, hormonal preventives still provide an effectual agencies of birth control that may outweigh the assorted side effects. However, drug companies and doctors need to accurately province the likeliness of the side effects so that adult females and their households can do an informed determination when make up one's minding to utilize this signifier of birth control – besides, this can increase the chance that adult females will go on to take the pills on a regular basis and run into their terminal ends ( Freeman, Shulman, 2008. )

Compare and contrast Ralph and Jack as leaders Essay

Ralph and Jack signify different themes and ideas throughout ‘The Lord of the Flies’. They both have different personalities but in some aspects they are similar. For example, they both want to be leaders, but they want to lead in different ways. The two boys are from typical English public schools so their background is similar yet their personalities contrast. Ralph is calm and fair; he represents order, leadership and civilisation. On the other hand Jack is very authoritative and represents unbridled savagery and desire for power. As the book progresses we see these traits becoming even stronger in Jack, as if he were a dictator like Hitler from the Second World War, which was when the ‘Lord of the Flies’ was set. When Ralph first finds himself stranded on the island, it is as if he couldn’t care less as to how he got there. The fact that he has just survived a plane crash, in which many adults have died in, does not seem to bother him at all. The first thing he does is rip off all his clothes and swim in the lagoon. This is quite childish behaviour and the fact that he is ripping off all his clothes shows that he is already starting to stray away from civilisation. It is not until Piggy finds him and starts asking intellectual questions as to how they got there and whether there is anyone else on the island that he starts to vaguely consider the situation. As the book progresses Jack emerges with his choir. It is obvious that he is in control, ‘he shouted an order and they halted’. This shows he is an authoritative figure and the impression is given that he is controlling an army. Even though the two boys have not met, it is immediately clear that there are differences between them. Ralph is calmer and quite happy to take everything in his stride, whereas Jack remains in his choir uniform and still acts with a large sense of responsibility despite the fact he is hundreds of miles away from civilisation. Ralph is democratic and more thoughtful. For example, before anything happens about being rescued he says ‘we ought to have a chief to decide things.’ Jack shows his arrogance emerges when he replies, ‘I ought to be chief’, as if he was a dictator without any care for other people’s opinions. In reply Ralph uses his democratic approach and decides, ‘Let’s have a vote’. Ralph’s decision to have a vote shows how fair he is and his approach to become a leader is democratic. On the other hand, it is clear that Jack is very self-centred and is prepared to push for the position of leader even if it happens in a manner not popular with the other boys. The situation of the Second World War is being reflected in the two boys’ contrasting personalities. As the time that is spent on the island advances, Jack’s savage traits start to emerge. For example, when he goes hunting he lets the boys go off swimming whilst he continues. Unfortunately he catches nothing and goes back to camp. He describes the situation to Ralph, ‘I went on. I thought, by myself’ †¦ ‘the madness came into his eyes again’ †¦ ‘I thought I might kill’. Jack’s true traits are starting to emerge. His savage instinct is starting to become apparent; he is described as having madness in his eyes. He is starting to have a ‘compulsion’ to hunt and kill that was not apparent before because society and civilisation keeps people in control but when they are set free from this their natural or basic instincts start to emerge. However this is not true of everyone, Ralph has continued to remain calm and civilised;, building huts on the beach with Piggy, his advisor. His natural instincts are not savage but to try to find a means of remaining safe and being rescued. Throughout the book Ralph relies on Piggy to help him with many decisions. The idea to blow the conch so that other boys would emerge from the island was Piggy’s idea as well as the idea to use his glasses to start the fire on the mountain. Piggy’s pragmatic and intellectual approach to the situation they are in helps Ralph yet sometimes the boys do not listen to him, especially Jack. Jack has a very autocratic approach and feels he can make the correct decisions himself. His decline into savagery becomes apparent due to this and results in him punching Piggy and eventually killing him. For example after Piggy notices there is no smoke he tells Ralph but there is not much they can do, as the boys who were supposed to be watching the fire had gone hunting. Soon enough they notice a large group of figures coming down the beach chanting, ‘Kill the pig, Cut her throat. Spill her blood’. Jack is part of this group and it is apparent that the other boys have also acquired a lust for killing and hunting. However, Piggy drives Jack to violence by saying, ‘You didn’t ought to have let that fire out, you said you’d keep the smoke going’. After this Jack hits Piggy; Jack has lost the self control that was in place before he was held back from violence due to the moral trappings of society. Later on in the book, Jack’s leadership starts to become more appealing to the boys. The lifestyle he is offering them with meat and protection from the beast is compelling for them in some aspects, ‘To-night we’re having a feast. We’ve killed a pig and we’ve got meat. You can come and eat with us if you like’. Eventually all the boys start to switch to Jack as their leader. The boys have lost sight of what being civilise means and just want to follow a leader who offers a simple way of life; hunting, food and safety in the tribe. Ralph starts to give up hope, ‘So we can’t have a signal fire †¦ We’re beaten’. The two boys’ contrasting opinions and aims are in competition and at the beginning of the book when society and civilisation was still in the minds of many of the boys they were prepared to have Ralph as their leader. However, as time has passed and their sense of civilisation has gradually disappeared the longer they are away from it, they have resorted to Jack for fun and a preferred lifestyle. In some aspects Ralph and Jack are alike as leaders because they both want to get their own way. However their aims are different, Jack wants to hunt and Ralph wants to be rescued. Jack is the autocratic, less caring leader whereas Ralph is democratic and tries to do what is best for all the boys. In the end it turns out that the boys would prefer to be led by Jack. Golding is suggesting that it doesn’t matter who you are, even if you are from a privileged public school background, without the influences of society we will decline into savagery and our true natural instincts will emerge.

Originally, there was the Emperor Diocletian who ruled over the then-Roman empire. During this rule, the empire was cut into four administrative units each of which were governed by a tetrarch. The tetrarchs can be observed in famous sculptures from this period, which came before the Late Antiquity period around 305 A.D. This sculpture shows all four together, looking decidedly similar, the impact of which was meant to show that there was unity and stability in the four governing units. Emperor Diocletian’s rule began to break as Constantine was able to defeat the former tetrarch Maxentius during the Battle of the Milvian Bridge. After his victory, Constantine assumed the position of ruler and began to implement many changes including the promotion of the new religion: Christianity. In part because of this new religion and because of his triumph in battle he had the Church of St. Peter constructed in honor of the victory. The new church was an architectural masterpiece, one which brought about many new elements not only of this new religion but of this new rule. While the church would have been considered a temple by the Romans and the architecture used for it were typical of Roman public buildings, it was given the name â€Å"basilica† to honor the many new traits it embodied. Other churches which remain today as an example of the architecture and artwork from this era include the Basilica of Constantine located in Trier in Germany. This building has the famous clerestory, the sunken ceiling panels, the lunette, the apse, and the ambulatory all associated with the Late Antiquity period. Some of the new traits included the representation of the new religious leader: Jesus Christ. His earliest artistic depicture is that of the Good Shephard, something which can be viewed in the basilica, and other buildings constructed during this time. The church also boasted an altar located in alignment with the east. At the end of the later was the apse. There existed an ambulatory which was the passageway which surrounded the altar of a church. The overarching structure relied upon the axially planned church and featured third level windows called clerestories and the sunken panels inside of the ceiling. Over the doorway leading to the entrance of the church were lunettes, or, a crescent-shaped space, inside of which paintings or sculptures were held. Outside of the church was the atrium, or courtyard where more artistic displays were found. The artwork commissioned during this time reflected upon the new gospels which were used by the new religion. During this time people used t he first four books, or Gospels. These books were written by the Four Evangelists who are all portrayed in a great deal of art from the time as different celestial animals. Eagles were used to construe both Matthew and John. Mark was painted as a lion. Luke was portrayed as a bull. Changes with relation to how the dead were handled also took place, and were another way for artistic displays to find prominence. During this rule, catacombs, or underground network of passages in which to bury the dead. Inside of the catacombs were paintings across the walls and ceilings all of which showed pictures of salvation. These paintings covered the cubicula’s which were small rooms known as mortuary chapels as well as the loculi were the openings in the walls. The mausoleums were another type of building intended to memorialize the dead and show simultaneously how unimportant the physical body was by incorporating the bodies into the ceremonies. This can be viewed in many artistic pieces found here including the Ravenna in the Mausoleum of Galla Placidia where it remains today. This piece is found on the lunette and dates to between 425 and 500 A.D. As a leader Constantine is featured alongside the purple colors in many pieces of art. The Porphyry stone was purple, and it was reserved for the emperors. It is for this reason that the artwork consisting of leadership or rulers from the time have purple hues. Additionally, Constantine sought to bring a message with his rule and did so by having sculptures of himself made. One such remaining example is the colossal head of Constantine, which came from the Late Antiquity period and is dated to between 310 and 330 A.D. His head is like many statues of Constantine which were designed with a message: the open and unblinking eyes were meant to tell his people that he was always watching.

Of course, its all in the eye of the beholder.  The same can be said for the adjective pretty which is used with women. Whereas, cute is used when referring to either sex.   This is also true when speaking about a persons character. Any adjective can be used to describe either sex, but some are more common than others. Of course, these days, many people rightly complain about such stereotypes. Still, there are preferences that lie deep in the English language. Guys and gals used to be used to refer to men and women in an informal manner. These days, its common to refer to everyone as guys. Job names have also changed over the years. Its common to change words like businessman to businesswoman or business person. Other job titles such as stewardess are no longer in use.   These changes in vocabulary is an example of how English commonly changes with the times.

Nothosaurus - Facts and Figures

Nothosaurus - Facts and Figures Name: Nothosaurus (Greek for false lizard); pronounced NO-tho-SORE-us Habitat: Oceans worldwide Historical Period: Triassic (250-200 million years ago) Size and Weight: About 10 feet long and 150-200 pounds Diet: Fish and crustaceans Distinguishing Characteristics: Long, tapered body; narrow head with numerous teeth; semi-aquatic lifestyle About Nothosaurus With its webbed front and back feet, flexible knees and ankles, and long neck and tapered bodynot to mention its numerous teethNothosaurus was a formidable marine reptile that prospered across the nearly 50 million years of the Triassic period. Because it bears a superficial resemblance to modern seals, paleontologists speculate that Nothosaurus may have spent at least some of its time on land; its clear that this vertebrate breathed air, as evidenced by the two nostrils on the top end of its snout, and although it was undoubtedly a sleek swimmer, it wasnt as well adapted to a full-time aquatic lifestyle as later pliosaurs and plesiosaurs like Cryptoclidus and Elasmosaurus. (Nothosaurus is the best known of the family of marine reptiles known as nothosaurs; another well-attested genus is Lariosaurus.) Although its not widely known to the general public, Nothosaurus is one of the most important marine reptiles in the fossil record. There are over a dozen named species of this deep-sea predator, ranging from the type species (N. mirabilis, erected in 1834) to N. zhangi, erected in 2014, and it apparently had a worldwide distribution during the Triassic period, with fossil specimens discovered as far afield as western Europe, northern Africa and eastern Asia. There is also speculation that Nothosaurus, or a closely related genus of nothosaur, was the distant ancestor of the giant plesiosaurs Liopleurodon and Cryptoclidus, which were an order of magnitude bigger and more dangerous!

Communication and Language Essay Example | Topics and Well Written Essays - 4000 words

Communication and Language - Essay Example He will now look at and reach rather than grasp an object as an adult presents it. He has also become more willing to perform familiar actions on an object without mouthing it but using his hands to hold and manipulate objects for longer. He has also shown greater attention to where objects move to or from during the activity. This has been particularly noticeable during our greeting sessions. At the beginning of September he needed adult coactive support to tap a drum to say ‘hello’, as he has become more familiar with activity where he begun to use both hands to tap a drum with adult verbal encouragement. Now he will reach instruments spontaneously to say ‘hello’ as adult moves around the circle asking ‘who want to say hello first’. He is also able to indicate if he wants to continue the tapping action or he finished saying ‘hello’ by clapping his hands to indicate more or pushing the drum away. He finds it amusing if an adult cop ies his simple drumming actions, responds with a smile, and listens to it. Interacting Pupil's progress Charlie has been working towards developing his interaction and playing skills with adult and peers. Charlie has made steady progress with developing his communication, social, and interactive skills with class staff and peers as the year has progressed. He has shown an increasing interest in trying to influence the adult actions during self-occupation time to get what he wants or during group session as mentioned above and one-to-one sessions such as interactive games focusing on communication, taking turns, interacting and responding to adult partner. For example, simple hand clapping games that requires him to form quick thinking, cooperation, and reaction to a game like clapping one's own hands, clapping both hands of a partner, and clapping one hand of a partner, generally across such as the right hand of each player at an appropriate junction.   During self-occupation time , he will move in the direction of the plasma screen and make brief eye contact with an adult to let them know what he wants. If the adult ignores his communication, he will walk around the plasma screen, look behind the speakers, turn on a socket plague and manipulate a key to open the box with laptop attached to the screen. During leisure time, when approached by an adult and asked, â€Å"what you want Charlie?† he will hold his hand and guide him in the direction of the plasma screen or balcony / class door to watch his friends playing or to go for a walk. He is now learning to transfer these learnt skills to class activities. Last year, Charlie preferred contact with adults to that with peers, but this year he has been starting to pay more attention to his class friends if he is engaged in a simple game with them or when they are exploring interesting things. For example, he will pay attention to an interesting object controlled by another pupil, and will come to him or h er, reach for the item and explore it for brief moment before giving it back to his peer.

Dance Class Article Example | Topics and Well Written Essays - 750 words

Dance Class - Article Example I remember that in the last letter that I sent to you, I had explained to you why you should not fear or hesitate to take a course in dancing. This time round, I want to share with you my concrete experiences in this course, so that you can be can be convinced that this course is indeed quite important. First of all, let me share with you the expectations that I had before taken this course, and how I have been able to realize my expectations after taking the course. One of the major expectations that I had before taken this course was that the course would enable me to know the history of dance and the important people who have had great influence in the history of dance. Through this course, I have really been able to realize this expectation. This is because we have studied extensively about the history of dance and the important personalities like Gus Giordano, Jack Cole, and Agnes DeMille, who have had the great impact in the world of dance, especially dance in the Jazz music. For this reason, therefore, I am now conversant with the history of dance. The second major expectation that I had when I started this course was that the course would enable me to know different dancing styles, both modern traditional styles. Through the training that we undergo in this course, I have be en able to realize this expectation. Although of course, I don’t claim to have become an expert in dancing overnight, I have learned different dancing styles in this course and I am able to dance to different types of music like Jazz songs.

It is one of the world’s largest brokers of decorative and fine arts real estate, jewelry, and collectibles (Innovation, Theories of Art, and Sotheby’s Company 2011, 63). The company divides its operations into three segments. These include finance, Dealer and auction. Among other products and services, the company deals in a range of services including Private Sales to Corporate Art Services. Traditional operations of Sotheby†™s Company make it the fourth oldest auctioneering company in continuous operation in over 40 countries and with 90 locations worldwide (Gus 2012, 44). By December 2011, the company boasted of 1446 employees worldwide. Sotheby’s is arguably the world’s largest art enterprise with global sales that totaled up to $5.8 billion in 2011 (Gus 2012, 44). Relative success of the company can be attributed to its efficient mode of operation that it established right from its inception in 1744 in London. The company has maintained a culture of management that looked at the business in three distinct dimensions. The company viewed and treated the business as having the categories of finance, auctions and finance. Sotheby’s is a master at managing timing during biding struggles among wealthy buyers. This is a unique piece of art the company has learnt to perfect and preserve over the years. Auctioneering capabilities of the company has made it become a marketing timer as w ell.

Project Management in a Changing Environment Coursework

Project Management in a Changing Environment - Coursework Example A new body of knowledge was evolved, which came to be known as Project Management. Over the years, the science of Project Management has developed enormously and many scholars and practitioners have introduced various tools and techniques to enrich it. Â  Internet, computers, project management software etc have enhanced the pace of development of project management.Successful completion of a project on time with the use of limited resources and minimum cost is the main objective of project management. But, project management in modern times is no longer possible by paying attention to resources, cost and time alone. The project managers are forced to look beyond time, cost and resources. The traditional tools and techniques such as Gantt chart, PERT/CPM networks became powerless and attainment of project objective remained a dream for the competent project managers. A careful analysis has been made in various areas of project management and finally reached a way-out that project ma nagers need to have a check on the rapidly changing environment in which the project needs to be materialized.Every project is carried out in a set of complex factors. The totality of all such factors is known as the project environment. Time, organizational factors, a legal system, political system, technology structure, economic system, socio-cultural system are some of the factors in the project environment. All these factors are likely to affect projects and the success depends upon how the project manager and his team respond and adapt to the changes. The basic principles of project management still remain effective in any contexts regardless of size and time. But the resources, budgets, methods, and tools of the project depend upon the environment. If today’s projects are managed by the tools of the past, the probability of failing the project is very high. That does not mean that traditional tools are ineffective in modern times. Thus, before implementing the tools, th ey must be made adaptable to the changed resources, budgets.

Leadership Assignment Example | Topics and Well Written Essays - 4000 words

Leadership - Assignment Example Toffler’s (1970) conception of â€Å"transcience† was way ahead of its time. Looking forward more than 3 decades ahead, he has painted a frightening picture of how weary the situation will be if one will not be able to adapt to the ongoing acceleration of change. Transcience is the feeling of temporariness and impermanence which is what Toffler predicted would be the adjustment mechanism of contemporary man. In terms of employment, transcience may be seen in how employees cannot stay put in one job as they grab as many opportunities as they could just to get ahead. They may jump from one job to another, eager to try out the latest job openings in the newest companies. Such restlessness evades the development of loyalty to the current employer and even hinders the formation of strong bonds with co-workers. Ideally, young workers seek jobs related to their interests. However, when the need for a job is at hand, they may forsake their interest and take whatever job is avai lable. They find out more about the job in the early days, and get to gauge if they have chosen well or not, a job that they can establish their career on. As employees vacillate from job to job, they try to find what is in it for them†¦ is it challenging enough? Does it tap into their skills? Does it pay better? Hence, managers should make job offers as attractive as possible to recruit the best candidate for the position. Transcience significantly impacts an organization’s performance, as the frequent loss of employees to other companies can paralyze operations. Recruiting and training new staff involves a great deal of time, effort and resources that may drain the organization and hamper its smooth flow. Managers would prefer to work with a steady group of workers that would grow with the company. Providing an orientation to the job at hand is crucial in an employees’ decision to stick with a company for a long time. As in most situations, the first impression usually sets the expectations of people. Managers must prepare well for such an orientation because it is one way to send a clear signal to the employee that the organization is committed to his success. Organizational-level orientation intends for employees to feel welcomed and that they are now part of the organization; learn more about the organizational mission and vision, culture, language, history and structure. Employees come to better understand the basic workplace principles and policies. It prevents unwanted employee turnover is the provision of an effective orientation program to guide new hires through their jobs and the company in general. Even an experienced professional can be vulnerable to feeling abandoned when he is left on his own to survive unaided in a new and strange work environment. Apart from a standard employment contract, employees may also wittingly or unwittingly expect a â€Å"psychological contract† with the employer that includes open and hones t communication, managerial support and challenging and interesting work. Employees are becoming increasingly aware of the non-monetary rewards that companies can provide them. It is generally important that the job not only fulfills their economical needs, but their socio-emotional needs as well. This means a discussion of compensation and benefits should go beyond the concrete rewards of the

Tsunami Resisting Structure Design

Tsunami Resisting Structure Design Tsunami waves Abstract: In the past Lebanon has experienced some major earthquakes and tsunamis. Kids are taught at school that Lebanons capital Beirut was buried 9 times because of these catastrophic events. However, other than manmade disasters, modern situation has been calm and this small Mediterranean country has been tsunami free for quite some time. Unfortunately studies show that this situation will not remain as calm in the future and that the Lebanese coast is in danger of re-experiencing these waves. In this paper the historic Tsunami activity around the world will be reviewed and evidence shall be given on why this event will strike Lebanon after 1500 years of absence. In addition, the behaviors and characteristics of tsunamis will be presented, how they start and how they destroy and by knowing the effects they have on buildings and the damages they cause to their elements, we are able to design a structure with the purpose of resisting these loads. The aim of this study is to design a Tsunami Resisting Structure in accordance with the current guidelines and complying with the existing Standards and Codes, that is expected to provide safe refugee from Tsunami and earthquakes. An example shall be given and the applied loads shall be calculated in the following pages. Introduction: It is said in the bible that the Lord told Noah that a flood of waters shall be brought upon the Earth to destroy mankind, both man and beast shall drown (Genesis 6:17). Tsunamis have been happening since the beginning of time, in the past as well as in our days when that event occurred, as part of evacuation technique or simply by instincts for survival people try to escape by going inland or trying to reach higher altitudes. But the wave hits the land with great energy and speed that basically trying to race it horizontally is practically impossible and most casualties that happen during a tsunami is when people try to flee the coast and move inland to higher altitudes. In some areas an evacuation is not possible in time and the best chances people have is through a vertical evacuation by moving upwards to higher levels in a tsunami resisting structure. (FEMA P646A, 2009) The idea of a vertical evacuation structure came to be after the tragic Sumatra earthquake and Indian Ocean tsunami in December 26, 2004. 300,000 lives were lost in the boxing day tsunami (Christian Meinig et al.,2005), and that number would have been so much worse if Reinforced Concrete Structure did not act as shelters for survivals. (FEMA P646A, 2009) We learnt from past events, and if a concrete multistory house was able to resist, even it was temporarily, even if it was for a short term, then a structure can be designed to withstand Tsunami as well as earthquakes, because in most cases, these two hazards are connected. Definition: The Federal Emergency Management Agency (FEMA) and the National Oceanic Atmospheric Administration (NOAA) explain tsunami as: A Tsunami is a naturally occurring series of ocean waves resulting from a rapid, large-scale disturbance in a body of water.). They can be caused by either volcano eruption under water, or earthquake or landslides etc. (FEMA P646A, 2009). When they travel in the ocean the waves and fast but short in height, but when they reach the coast, the waves gain in height. It was believed that a number of events led to these oceanic waves however after the study of past events it was concluded that the major cause for tsunami generations was due to tectonic movements. Katsuyuki Abe in his publication Tsunami and Mechanism of great earthquakes explains the relationship between these waves and earthquakes. Katsuyuki Abe said: tsunamis are generated by tectonic deformations rather than by large submarine landslides and slumps. (Katsuyuki Abe, 1972). When tectonic plates are active, plate deformation induces seismic activity that cause earthquakes (Stein and Klosko, 2002) and The source of the tsunami/earthquake can be tracked back to its origin by analyzing the arrival date of the first wave to the shore. The boxing day 2004 Tsunami went down in history as the deadliest tsunami, with more than 230,000 casualties across 14 countries The earthquake triggering the tsunami was of magnitude 9, the most powerful earthquake in 40 years (ABC news, 2014). With its epicenter located at the Sumatra coast, between 2 tectonic plates, the Indian plate and the Burma plate. The two plates were so stressed that the earthquake happen when the Indian plate slipped under the Burma plate. (Sudhir et al., 2005) Tsunami in Lebanon No matter where we read or heard it, whether it was in the findings and studies published by the National Council for Scientific Research, Beirut, Lebanon or National Center for Geophysics, Lebanon or even in the August issue of the journal Geology 2007 or National Geographic News or Discovery News channel or the local newspapers, the context were the same: It is just a matter of time before a destructive tsunami hits this region. An underwater survey placed Lebanon near an active fault that could generate an earthquake in the seafloor causing a devastating tsunami in the region. Elias Ata and colleagues researched that the same fault that was responsible for the strongest earthquakes in the Mediterranean is active and is in danger of producing a tsunami wave just like it did thousands of years ago in the 551 A.D. tsunami in Phenecia now known as Lebanon (Elias et al, 2007). They confirmed the presence of fresh seismic breaks in the sea floor and argued that the Mount Lebanon thrust is identified as repeated earthquakes with 1500 years of return. Since the last earthquake was in 551 A.D. with an active fault line and a 1500 recurrence period, an earthquake in water is bound to happen any day now, and a tsunami will hit the entire Lebanese coast from north to south. Fortunately complying with the Lebanese building code for construction and design is deem to satisfy conditions for earthquake and seismic analysis, but the law does not impose tsunami design to developers and consultants and the idea of a tsunami resisting structure or a vertical evacuation model was somehow absurd in the region. However now that we have solid proof of a predicted tsunami, that idea doesnt look absurd anymore. Structural system A basic concept design of a Tsunami/Earthquake proof structure follows a number of consideration and guidelines. After observing past events, we can conclude that the major element that contributes to the survival of houses was the material used. While most small residences in Australia are timber and lightweight systems or even brick veneer and load bearing wall system, the most robust model that can resist important horizontal or vertical loads is reinforced concrete and or Steel structures. Multistory building are heavier and thus can prevent sliding when horizontal action is applied and because above levels are not submerged they aid to resist lateral loads. Another key component is Orientation, when buildings are constructed in a direction parallel to the ocean, the wave will have a greater surface of contact, and therefore the lateral force will hit the plan faà §ade with the lowest inertia. When they are built perpendicular to the ocean, the contact surface is smaller and the pressure will act upon a direction of highest inertia.   An ideal design is to not resist entirely the wave and have the structure with 800mm thick reinforced concrete wall. It must be a combination between a robust design combined with weak members. In other word, the wave should pass through the building, without causing the collapse of above stories. In order for the wave to flow though the ground level, non-load bearing walls have to breakaway to make passage for the wave. These breakaway walls are masonry block walls, they collapse once struck by the wave.   (FEMA TB9, 99) How vulnerable Structures are? Observation to partially damaged houses indicated that all elements can fail under tsunami load. Foundation can be uplifted and soil can be scoured. Columns can be sheared causing one story collapse or leading to progressive collapses of all upper levels and impact force can completely dislocate columns. Beams can be bent lateraly due to horizontal action and were majorly cracked. Joints connecting two elements, such as vertical support with slab and foundation can fail entirely. Shear and bending failure in walls have been detected, and punching shear where an axial element punches through a plan system was observed as well. However studying only the elements that failed is not enough; engineers must also consider the components that survived. For instance, it was that facades that had openings such as windows and doors did not crumple as opposing to sides there were completely closed and thus have been ruined by the wave. Calculation example This example consists of determining the actions caused by a tsunami on a structure of 2 basements, parking of area 1800 m2 each, Ground Level , Mezzanine and ten stories. The site is located 200 m from the shoreline, at elevation 5 m from the sea level near Beirut, Lebanon Elevation profile indicating the different slopes and location of the structure, taken from Google  Ãƒâ€šÃ‚   Earth 3D The slope of the terrain is essential to determine the wave parameters, specially height. The Federal Emergency Management Agency FEMA, has set guidelines to design structure from tsunami waves, FEMA P646 and FEMA P646A, 2005 shall be demonstrated in the below paragraphs to calculate all the loads generated on our structure. But first we need to determine the waves properties. A tsunami wave is defined by its inundation elevation R*, with is the height of the wave at its maximum penetration. Given the topography of our project, the wave will reach the steep slope and retrieve back, thats 510m from the shore. To determine the height, we will assume that the height is 10m Tsunami Loads As per FEMA P646A, 2005 8 forces are acted upon the structure: Hydrostatic, Buoyant, Hydrodynamic, Impulsive , Debris impact, Debris damming and Uplift forces, not to mention Additional gravity loads from retained water on elevated floors. Hydrostatic force in the basement is when the water from tsunami is retained in the basement, and cannot escape because the basement wall outline prevent seepage, the water is trapped and the basements are compared to water reservoirs since the two basements are completely filled with water. A static analysis on reservoir will therefore be conducted with water height 12m (=6m+8m) Fluid density à Ã‚ s = 1.2 à Ã‚ water = 1200 kg/m3 pc is the hydrostatic pressure, pc = à Ã‚ s.g.h pc (at GL ) = à Ã‚ s. h = 1200 x 8 = 9.6 T/m2 pc (at 1st Bas. ) = à Ã‚ s. h = 1200 x (8+ 3) = 13.2 T/m2 pc (at 2nd Bas.) = à Ã‚ s. h = 1200 x (8+6) = 16.8 T/m2 Buoyant Force The uplift force as per Archimedes principle is as follow: The reinforced concrete has a specific gravity of 2.5 T/m3, in our case the slab isnt a solid slab but made of hollow blocks with self weight equal to 0.63 T/m2 Specific gravity of a 32 cm slab of hollow blocks is = 1.97 T/m3 Water has a specific gravity of 1.2 T/m3 When immersed in the water the slab wont weight the same actuality it would weigh less due to the fact it has a buoyant force acting upward making it lighter. And so in water, the specific gravity of the slab will become 1.97 T/m3-1.2 T/m3 = 0.77 T/m3 If we take into consideration the thickness of the slab 32 cm it becomes   0.77 T/m3 x 0.32m = 0.246 T/m2 The buoyant pressure decreased the specific gravity of the slab from 0.63 T/m2   to 0.246 T/m2 so it must be equal to 0.63 T/m2   0.246 T/m2 = 0.384 T/m2 The buoyant force will be applied upwards as uniform surface load 0.384 T/m2 acting on floors of  Ãƒâ€šÃ‚   1stBasement, Ground level, Mezzanine and first floor.
