Leadership in Difficult Times - Research Paper Example A beautiful landscape comprising of Colorado Mountains: Mt. Antero, Mt. Princeton and Chalk Cliffs, surrounds the Ranch which increases the attraction of the place. The Wolmingtons have been the most gracious and kind hosts in the entire Colorado as their guests (more of clients) continue to repeat their returns year after year. There are guest rooms, family lunches and dinners, hunting time with exciting adventures and do-it-yourself guides that allow their clients to feel at home (â€Å"DVR†, 2012). After the death of Clara, Parker thought he was left alone. However, his fourth generation has now taken over the Deer Valley Ranch operations and continues to offer the same homely feeling and adventure to their guests which Parker and Clara together provided. At the age of 94, Parker died in 2011. Now, Levi, Halley, Cora, Daniel and Jordan are the heirs of the Deer Valley Ranch and have to ensure that it continues to thrive like before. Today is 19th March, 2012. Daniel woke up from his bed after a beautiful night sleep. It has been almost five months since Parker’s death, and things have been moving smoothly. Daniel smiled and lazily moved towards the morning newspaper lying on the breakfast table. Levi was in the kitchen and beautiful aroma of baked bread and hot coffee drifting from there and fresh morning air from the Colorado Mountains broadened Daniel’s smile even further. ... All of them like Daniel for his leadership qualities and the ability to envisage team working spirit in the Ranch that has only benefitted the entire Ranch family which includes its clients. But things do not remain all the same every day. Daniel took up the newspaper and all of a sudden, his smile turned into a horror stricken one. A shout from his mouth left Levi stranded between the desire to run to Daniel and the bread in the oven that was only seconds from ready. Levi’s mind decided for the former and she ran to Daniel who was pulling hard on the arm chair. â€Å"What happened?† asked Levi. Getting no response, she filled a glass of water and put it to Daniel’s lips. He took a long swallow of water and his mind started working. â€Å"We are in the recessions. Prices of food and inflation have risen tremendously and we have 7,000 deer and one goat in the Ranch to feed. How are we going to save our Ranch within no time?† said Daniel with a perplexed exp ression. â€Å"Don’t worry, everything will be alright†, answered Levi with a confident smile. â€Å"We just need to inform others and devise a strategy to save the deer from dying† said Levi. â€Å"Yes, you are right. Let me call Jordan, Halley and Cora. We should immediately sort out this matter†, exclaimed Daniel. Within an hour, all of the five heirs of Deer Valley Ranch were sitting outside the Ranch House. â€Å"We have to save our Grandparent’s Ranch as it means everything to us. The prices of the food have increased three times as of today’s newspaper. We have 7,000 deer and only one goat in the Ranch, which means we will not be able to provide the required level of food in terms of quantity and quality to

The United States Consumption of Nonrenewable Resources Essay Example for Free

The United States Consumption of Nonrenewable Resources Essay The United States consumes 85% of nonrenewable energy sources to provide energy throughout the states: 40% comes from oil, 23% from natural gas, and 22% from coal. These nonrenewable energy sources are also called fossil fuels, which take about 300 million years in the making. Fossil fuels are termed nonrenewable because they are not easily reproduced. The U. S. can produce a considerable amount of petroleum. But the increased energy consumption leads to the gradual depletion of its petroleum reserves. Thus, U. S. has been importing oil since 1939. U. S. also depends on natural gas, which is a by-product of oil production. Since petroleum reserves of U. S. is depleting, production of natural gas is also affected. U. S. imports natural gas from Canada. About 27% of coal reserves is found in U. S. Since 1950, U. S. has been producing more coal than it can consume. U. S. exports the surplus to Canada, Brazil, and Italy among others. But U. S. coal reserves are also facing depletion. So coal exportation has decreased since 1991. Increased energy consumption can be attributed to increasing population, rapid industrialization, and continuous economic expansion. The increased energy consumption leads to the utilization of more of the now limited natural resources. According to the Energy Information Administration (EIA), the United States’ total energy consumption is estimated to rise from 97. 7 to 136. 5 quadrillion Btu between 2002 and 2025. What will happen to U. S. ’s energy situation? One, continued use of fossil fuels will increase emission of carbon dioxide and will intensify today’s problem on global warming and acid rain. Two, since there is scarcity of nonrenewable energy sources, U. S. , in the future might exhaust all of these. Importation could be the next step, but budget should be considered. Last, U. S. might exhaust other countries’ sources on nonrenewable energy, too. When this happens, the world might experience the greatest energy crisis ever. Think wisely! Act wisely! Conserve energy now!

Heat Transfer Within A Jacketed Reactor System

Heat Transfer Within A Jacketed Reactor System Modeling of heat transfer within a jacketed reactor requires basic knowledge on process heat transfer; reactor design etc. literature review sum up the fundamental on energy balance, method of overall heat transfer coefficient determination and basic understanding of crystallization. These are the basic methods which allow engineers to predict more accurate capabilities during chemical process as well as timing on the process. Introduction Heat transfer is important in agitated vessels due to fluid temperature is the most significant factor for controlling the outcome of chemical, biochemical and pharmaceutical processes. [6] Jacketed agitated vessels for heating and cooling are commonly used in vary types of process applications. Engineers should have working knowledge of how heat transfer and temperature control principles applied to such vessels. Cooling or heating agitated liquid in vessels is a basic technological operation on the chemical, biochemical, pharmaceutical, food and processing industries. The cooling or heating rate depends on how the heat is supplied or removed, the mixing intensity and many other parameters. [5] The temperature needs to be controlled precisely at its desired to meet the requirement of downstream operations. Hence a mathematical model is essential which can predict temperatures accurately. The rate of heat transfer to or from an agitated liquid mass in a vessel is a function of the physical properties of that liquid and of the heating or cooling medium, the vessel geometry, and the degree of agitation. [8] Other factors which may affect the rate of heat transfer include type and size of the agitator and agitator location in the vessel. Most of the jacketed agitated vessels are used as reactor, thus chemical reactions with exothermic or endothermic effects must be taken into account as well. In a vessel containing an agitated liquid, heat transfer takes place mainly through conduction and forced convection, as it does in heat exchangers. [8] Crystallization is a unit operation for separation and production of pure solid materials with desired properties. To develop a batch cooling crystallization process, various operation strategies need to be investigated in relation to seeding, cooling, mixing, fines dissolution, and so forth. [18] In commercial scale process, the reactor size grows larger. In this situation, various problems like ancillary nucleation, attrition, breakage, agglomeration, and dead zone may become severer in relation to the increasing inhomogeneities in the solution temperature and hydrodynamics. Literature Review Modeling of reactors is useful for analyzing data, estimating performance, reactor scale-up, simulating start-up and shut down behavior, and control. [12] Uncertainties such as scale-up options, explosion hazards, runaway reactions, environmental emissions, reactor internals etc, may be explored through modeling. [12] A key aspect of modeling is to derive the appropriate momentum, mass or energy conservation equations for the reactor. One typical application in heat transfer with batch operation is heating the process fluid in reactor, maintaining temperature during the reaction period and cooling the product after reaction complete. [11] Energy Balance The overall thermal energy balance includes the heat entering the system, heat leaving the system, heat accumulation and heat loss. The equation can be written as: In batch process, there is no liquid or fluid entering or leaving the system. If the system is assumed to be perfectly insulated, the energy balance equation can be simplified in: [7] By integration of both sides: For a batch manufacturing process, heat transfer in an agitated vessel is used to design a suitable process or reaction. It is necessary to calculate the time to heat or cool a batch or the cooling capacity required to hold an exothermic or endothermic reaction at constant temperature. [1] The technique is to develop an expression which is relating time for heating or cooling agitated batches to coil or jacket area, heat-transfer coefficient, and the heat capacity of the vessel contents. [11] By rearranging the energy balancing equation, the relevant equation to calculate time is as follow: This equation only can be used in where the utility fluid temperature remains constant or the fluid temperature difference between inlet and outlet is not greater than 10% of the log mean temperature difference between the average temperature of the jacket and the temperature of the vessels content. [8] Precisely, for heating and cooling condition, this equation must be represented in separately: For heating: For cooling If the situation is greater than 10% of the log mean temperature difference, the apply equation will be: W = the mass flow rate through the jacket, C = the specific heat of the fluid in the jacket K = Assumptions are made for solving energy balance equation [11] [17] U is constant for the process and over the entire surface Liquid flow rates are constant Specific heats are constant for the process The heating or cooling medium has a constant inlet temperature Agitation produces a uniform batch fluid temperature No partial phase changes occurs Heat losses are negligible Agitated vessel heat transfer coefficient Process side heat transfer coefficient can be determined by speed and agitator type. For low viscosity fluids, high-speed turbine type agitators will provide good performance. For high viscosity fluids and non-newtonian fluids, larger diameter agitators will be more suitable. [1] Various types of agitators are used for mixing and blending as well as to promote heat transfer in vessels. The correlations used to estimate the heat transfer coefficient to the vessel wall. [2] For agitated vessels: Where hv = heat transfer coefficient to vessel wall or coil, Wm-2à ¢Ã¢â‚¬Å¾Ã†â€™-1 D = agitator diameter, m N = agitator, speed, rps (revolutions per second) Ï  = liquid density, kg/m3 kf = liquid thermal conductivity, Wm-1à ¢Ã¢â‚¬Å¾Ã†â€™-1 Cp = liquid specific heat capacity, J Kg-1à ¢Ã¢â‚¬Å¾Ã†â€™-1 ÃŽ ¼ = liquid viscosity, Nm-2s. The values of constant C and the indices a, b and c depend on the type of agitator the use of baffles, and whether the transfer is to the vessel wall or to coils. Some typical correlations are given below: [2] Flat blade disc turbine, baffled or unbaffled vessel, transfer to vessel wall, Re < 400: Flat blade disc turbine, baffled vessel, transfer to vessel wall, Re> 400: Overall heat transfer coefficient Most utility and process fluid will foul the heat transfer surfaces in an exchanger to a greater or lesser extent. The deposited material will normally have a relatively low thermal conductivity and will reduce the overall coefficient. Fouling factors usually are considered in determining the Overall heat transfer coefficient U. The overall heat transfer coefficient is calculated in this way: Where ÃŽ ± and ÃŽ ±s are the heat transfer coefficients for the process and utility side respectively. On the utility side, fouling resistance 1/ÃŽ ±f can be found from local experience or from Kern (1950). [1] Heat transfer utility fluid Syltherm 800 is a silicone heat transfer fluid. It is a highly stable, long-lasting silicone fluid designed for high temperature liquid phase operation. It exhibits low potential for fouling and can often remain in service for 10 years or more. The recommended using temperature range is. [15] Crystallization Crystallization occurs with generating a sufficient level of supersaturation. The method of generation of supersaturation is to provide heat transfer, which is used in cooling and evaporative crystallization processes. There are two essential steps for crystallization: nucleation and crystal growth. The problems of scale-up in crystallization process can be classified into induced, hydrodynamically induced, and mixes. For example, attrition, breakage, and agglomeration are related to solution mixing and are investigated from the hydrodynamic point of view. On the other hand, ancillary nucleation is caused by increased temperature gradient within the solution together with seed particles generated by attrition or fluid shear and can be considered as an example where the thermal and hydrodynamic effects are mixed. To improve the hydrodynamics deterioration during the scale-up, impeller type, agitation power, and baffle or draft tube design2,8,9 can be modified or newly designed as required. The thermal aspect improvement is performed by the heat transfer enhancement, but the remedies are limited because the heat transfer area to volume ratio decreases inevitably during the scale-up unless other techniques such as vacuum or evaporative crystallization is introduced. Methodology Calculation of time to heat or cool a fixed amount of liquid inside a batch reactor usually assume the process and utility heat capacity and the overall heat transfer coefficient to be constant throughout the calculations. Equations (liquid in jacket) heat input to reactor at T = heat loss by utility liquid with inlet temperature T1 and outlet temperature T2 Rearrange the equation to solve unknown jacket outlet temperature T2 The rate of temperature change of the liquid inside the vessel is given by Solving the above two equations to get process temperature as a function of time Finally, solving for time t where T = Tf Conclusion

Blakes Portrayal of Creation in Songs of Innocence and Experience Essa

In Jerusalem, Blake famously asserted that 'I will not reason and compare: my business is to create'. This quote highlights the fact that Blake himself was participating in an inventive process. Northrop Frye commented that 'man in his creative acts and perceptions is God, and God is man? ' man's creativity is, for Blake, the manifestation of the divine. The Songs of Innocence and Experience deal with life and the move, in particular, from youth to age. Creation is an extremely important aspect of life [being its beginning], whether the subject is creating or being created. As religion plays an enormous part in all of Blake's poetry, we can expect creation to have some biblical resonance as well. Songs of Innocence and Songs of Experience portray creation ? as they portray most themes ? in entirely different ways. The innocent child in The Lamb automatically answers his own question when he asks ?who made thee It was, of course, God. But the child?s simple reply conceals more ominous symbolism. By linking himself to the lamb and Christ, we are reminded uncomfortably of Christ?s great sacrifice and the slaughter of animals in honour of pagan gods. The simplistic, idealistic version of creation in Innocence veils the darker face of a sub-textually present knowledge involving ritual or religious sacrifice, perhaps the inevitable surrender of innocence in favour of experience. Creation in Experience is much more complex. In contrast to image of the lamb, the tiger is a predator, no longer ?meek? and ?mild? but ?fearful? and ?deadly?. The poem progresses with a series of questions, constantly gathering pace and frequency. The poem reaches a climax at the question ?Did He who made the lamb make thee The narrator cannot reco... ...hat it leads to more questions. Blake was almost certainly making a point about the nature in reality of experience, after we have created and have truly been created as adults, we begin to reach a higher understanding of what it means to exist, including the knowledge of death and contingency. This may make us bitter, but it also enables us to become wise, perhaps even reach a higher kind of innocence, a second childhood, in acceptance of the inevitability of age. So while the mother in Cradle Song sings sorrowfully ?Sleep, sleep, happy sleep,/ While o?er thee thy mother weep? in recognition that her child will one day reach experience, she is also able to see the ?Heavenly face?, which ?Smiles on thee, on me, on all?, regardless of age and experience. For, it seems to suggest, we are all His children, and He bears the same love for His creations as we do for ours.

Principles of Marketing: Individual Assignment Essay

‘Healthcare Marketing: What is Salient? ’ was written by Mary J. Kay from School of Business, Montclair State University, Montclair, New Jersey, USA. The purpose of the research is to develop a perspective on what is â€Å"salient† or critical to the discipline of healthcare marketing by analyzing and contrasting the consumer perspective with the organizational perspective. Based on the research report, in a complex institutional environment there is an existence of healthcare marketing. The difference of healthcare system in organizational and business structure significantly affect many priorities. In healthcare system, marketing significantly affect it. Thus, marketing are important and can play a role in the healthcare system – it provide the healthcare service and at the same time aiding the health information for consumer. The healthcare organizations usually will face many types of marketing problems due to organization and technology issues; and changes of health problem. So, this research discussed about the salient issues that are faced by healthcare marketing practitioner through contrasting it with consumer or patient perspective to the organizational perspective. From the consumer viewpoint, healthcare issues are important for them. The salient issues are framed in terms of cost and quality. The consumers are depending upon ‘trusted experts’ to evaluate the quality of the health services. The consumers need the quality of health services since they do not have any knowledge regarding the quality of health services. In their health decision, they are reluctant to accept lower quality of health services. Thus, critical or life-sustaining care should never be perceived by healthcare organizations because if they do, it will put a risk to organization’s reputation. For many critical treatment choices, consumer or patient always confront a lack of accessible of information to decide which brings the most benefits for them. In addition, there are many advanced technology that made new choices in testing that contribute to further decision dilemma. Also, choice is increasingly constrained by increasing in health insurance plans or national health programs. Thus, consumers need assistance to understand the critical components of medical care and regarding their decision. The pricing of the healthcare services is usually frustrating from the consumer perspective. High billings are especially troubling to the consumer or patients. Without a doubt, the quality, cost, and effectiveness of healthcare systems are complex interrelated matters that are difficult to understand. From the healthcare organization viewpoint which also involves doctors and staff, they are the ones who work harder to provide quality service, armed with medical knowledge and faced changing medical procedures. Quality is the main healthcare organizational priority but priority can be manifested differently in different healthcare organizations. The problems in fulfilling the demand of quality are difficult. There is some way that improving healthcare quality which is the doctor can be guided by good scientific practices which can be called as ‘evidence-based medicine’. But, there is a problem regarding this because of complexity of medical knowledge. Another way to improve the quality of healthcare services is by scientifically weighs the efficacy of differing treatment regimes. Through the system, the doctors are compulsory to utilize scientific databases that provide accurate information as to which treatments are working or not. Next, the quality priority shift due to technology advance. By advancing technology, the health priorities change as the root causes of health problems and new health threats come to light. Marketing for healthcare organizations is only managing the perception of quality by responding to customer satisfaction concerns. But, organizations also need to optimize real health outcomes. The quality of healthcare organizations needs to be understood in the scope of rising costs and changing treatment regimes. There are many issues related to medical industrial complex or can be describe as medical system. Firstly, issues according to positioning and resistance to change. ‘Affordable care’ is now the marketing buzzword used to justify any new ways in healthcare. This ‘affordable care’ is proposed by the government or politician. As the players in the medical system increased, it’s hard to change. The importance of strategies to develop a political consensus among the fragmented players in the healthcare system is apparent. As institutional processes and bureaucratic procedures become entrenched, healthcare systems are even more difficult to change. As a consequence, healthcare marketing, especially the type that would usefully improve health outcomes has become complicated by systemic problems due to the structure of the healthcare system. Next issues are about systemic problems. The systemic problems of healthcare can be examining through spending figure. Healthcare costs are higher due to the wage requirement. As an example in United State, the doctors are paid much more than their counterparts in other countries. Medical test and procedures are employed more frequently. USA is the major profit centre for pharmaceutical companies, who are able to price their products higher due to any lack of price controls. As medical costs are shifted to hospitals, the effect is to raise costs to other services as the burden is shifted to paying customers. As the cost is rising, it leads to many effects. The effects are health insurers and health management groups do not necessarily improve the overall the efficiency of the healthcare system. Market solutions are not apparent when it comes to healthcare. Thus, there is a dilemma in health reform. In the prospects for healthcare marketing, it has certain important contribution. There are two broad healthcare marketing problems which are relevant that would stand a chance of improving healthcare. The first is the important problem of consumer access to information that would improve patient healthcare decision-making. The second is the problem of the organizational diffusion of information which providing better access to â€Å"evidence-based medicine† to improve healthcare practice. Better publicizing treatment information and setting standards could improve healthcare and the role of marketing to positively affect health outcomes through promoting awareness of disease prevention measures is highly important. Some changing also may lead to the cost and organizational problems. Target marketing, specialization and fragmentation are important in maximizing health outcomes. The discipline of marketing provides tools and techniques for companies to profitably target consumer segments. Certain healthcare organizations have been able to profitably and effectively maximize the quality of outcomes for particular patient groups and in the process, have become increasingly specialized. However, as the healthcare system grows fragmented and specialized, issues of both cost and quality have been raised. Through DTC advertising and new marketing concerns, the educational quality of DTC can motivate discussions that enhance visit efficiency, patient/physician trust, patient satisfaction, or health outcomes. They found that while consumer attitudes are largely neutral, physician are usually negative, being distrustful of pharmaceutical promotions. There is new challenge in healthcare marketing. But, there are also ways to facing it. Public awareness of marketing campaigns can have an important impact. Given the behavioural aspects of many health problems, however, promotions alone can have limited effectiveness. Persuading people to change behaviours is a much more difficult problem than informing them about risks. Moreover, funding for better health awareness needs to be reconsidered as a public spending priority. Consumers (and their employers or insurers) make healthcare decisions within quasi-market system, and better access to salient healthcare information is clearly needed. Organizations clearly need to critically review treatment delivery systems to avoid mistakes and improve quality. Both consumers and healthcare organizations would benefit from more transparent systems to support healthcare decisions. The marketing challenge in healthcare is to develop and sustain better healthcare relationships for consumers. In my opinion, the marketing in healthcare systems is very significant due to its important role in providing the healthcare service also aiding the health information for consumer. In addition, healthcare organizations usually will face many types of marketing issues and problems as organizations, technologies health problem keep shifting and changing. The healthcare industry should engage in new thinking in understanding about their customers. They should find inspiration from other industries by scrutinizing the competition, health reform, consumer demands or the way they get to know their customers, moving beyond basic transactions and embracing their patients. Several service industries outside of healthcare are helping shape healthcare consumer experiences and expectations. Today’s technologically savvy consumers prefer to do their own research when selecting a doctor, investigating treatment options, and making major health care decisions. Targeted marketing also enables organizations to tailor communications to each stage of the member relationship. By identifying customer needs and be more prepared for the challenges and focused on raising the benefits of the healthcare services would markedly result in customer satisfaction and loyalty. Such situation can be illustrated by the recent big news when famous actress Angelina Jolie announced in a New York Times op-ed article on Tuesday 14 May 2013 that she underwent a preventive double mastectomy after learning that she carries a mutation of the BRCA1 gene, which sharply increases her risk of developing breast cancer and ovarian cancer. She signifies the empowered patient by deciding to be proactive in her health decision making!

Ethical Issues and Future Trends

Ethical Issues and Future Trends Abstract This essay analyzes two recent news stories wherein the issue of standard business communication consent forms has proved controversial. Legal action resulted when plaintiffs found that their DNA had been used and stored for purposes beyond the scope of the consent form and for which they did not give permission. Consent forms remain inadequate and incomplete in the area of DNA collection and do not provide proper information for donors so that they can make an informed choice about how their DNA will be used.Advertising We will write a custom essay sample on Ethical Issues and Future Trends specifically for you for only $16.05 $11/page Learn More Ethical Issues and Future Trends No one disputes the value of DNA research in the ongoing battle against disease. However, the business of scientific research in the future may face stiff ethical challenges on the basis of its existing communication tools. Universities and private DNA research firms often use consent forms to manage the acquisition and collection of DNA for one specific purpose, yet research itself often uses the DNA – without express permission from the donor – to underwrite a host of other unrelated research, some of which can cause harm to the donors. One such recent example occurred in the case of Arizona’s Havasupai tribe, based in the Grand Canyon (Harmon, 2010). In the early 1990s 41 members of the tribe donated samples of their blood and DNA to researchers working with the Arizona State University (Harmon, 2010). In April of 2010 these same members won a settlement against the University in the amount of $700,000, plus the return of their blood and samples, for what the tribe deemed â€Å"genetic era betrayal† (Harmon, 2010). The members discovered that the DNA they donated specifically for research into the tribe’s inordinately high incidence of type II diabetes onset was also used to support research into inbreeding, menta l illness and migration patterns of the tribe’s ancestors (Harmon, 2010). The tribe knew nothing of these others areas of research and did not offer permission for their DNA to be used in this manner. Also, the research employed to study the migration patterns and origins of the tribe’s ancestors suggested that the Havasupai arrived in North America via passage across the frozen Bering Sea (Harmon, 2010). This not only discredited the tribal elders’ stories, but also threatened to undermine the tribe’s sovereign rights and endanger their ongoing land claim battles (Harmon, 2010). The Arizona State University spent nearly $2 million contesting the lawsuits launched by the Havasupai by tribe members (Harmon, 2010). The April 2010 settlement â€Å"appears to be the first payment to individuals who said their DNA was misused† (Harmon, 2010). At the heart of this ethical issue lies the problem of the consent form. In the age of the business of scientifi c research’s increasing dependence of DNA to crack disease, to what extent does the consent form protect the rights of donors? This essay studies the case of the Havasupai tribe and so called â€Å"vulnerable† populations whose limited understanding of DNA research can lead to miscommunication and misappropriation in the business environment.Advertising Looking for essay on business economics? Let's see if we can help you! Get your first paper with 15% OFF Learn More DNA holds personal information, and in cases such as the Havasupai tribe, the consent form often does not adequately communicate the full scope of how this personal information may be used or in certain instances abused by the scientific industry. Similar to many other businesses, universities and private research firms typically employ a standard consent form to cover the harvesting of DNA from willing subjects. Federal law dictates that scientific researchers who hail from univer sity campuses as well as those private enterprises in the business of DNA collection and testing must obtain â€Å"informed consent† from subjects (Harmon, 2010). The idea behind these protections is to ensure that participants remain clear on their rights. However, the consent forms themselves typically originate from research that may expose participants to â€Å"physical risks, like experimental drug trials or surgery† (Harmon, 2010). These same consent forms often cannot predict the risks of DNA collection, since the culture surrounding DNA research demands full access. DNA donated for one purpose may prove useful for numerous others, and researchers themselves expect that once the DNA is in hand, all scientific uses become fair game. The geneticist who initially harvested and used the Havasupai blood samples, Therese Markow, upheld the ethical consistency of her actions within the scientific industry (Harmon, 2010). Her detractors, in Markow’s words,  "failed to understand the fundamental nature of genetic research, where progress often occurs from studies that do not appear to bear directly on a particular disease† (Harmon, 2010). In the words of David Karp, M.D., a professor of internal medicine at the University of Texas Southwestern Medical Center, â€Å"the potential benefit from unencumbered biomedical research trumps the value of individual control. Everyone wants to be open and transparent, [but] the question is, how far do you have to go? Do you have to create some massive database of people’s wishes for their DNA specimens?† (Harmon, 2010). The Havasupai tribes argued yes, and the court agreed with them. In another case that originated in Austin, Texas, a group of parents took federal legal action against the Texas Department of State Health Services, Commissioner David Lakey, M.D., Texas AM, and Texas AM Vice Chancellor for Health Affairs Nancy Dickey, M.D., for failure to produce satisfactory conse nt forms that informed parents of the collection and storage of blood drawn from their babies at birth (Roser, 2009). The parents’ lawsuit claimed that the defendants â€Å"unlawfully and deceptively collected blood samples from their children at time of birth and stored those samples indefinitely for undisclosed research purposes, without plaintiffs’ knowledge or consent† (Roser, 2009).Advertising We will write a custom essay sample on Ethical Issues and Future Trends specifically for you for only $16.05 $11/page Learn More The parents’ ire flared after they learned that their infant’s blood â€Å"was now state property† (Roser, 2009). The parents’ main fears stemmed from lack of information provided by the consent forms, and they were concerned that â€Å"the blood spots might be used someday to discriminate against their child† (Roser, 2009). The suit also charges that the state of Texas violates ex isting constitutional shields â€Å"against unlawful searches and seizures,† while simultaneously flouting existing privacy laws (Roser, 2009). DNA research offers infinite potential in the area of disease control. Medical advances certainly owe much of their sustained growth and innovation to the use of DNA. Support definitely exists for the continued use of DNA testing and research to combat debilitating conditions such as diabetes, Alzheimers, heart disease and cancer. However, business communication tools have not grown apace with DNA improvement, and as a result donors consistently receive inadequate information. The lack of information leads to lack of trust, and lack of trust in the public sphere has the potential to undermine public support, not to mention severely curtail the number of willing DNA donors. Existing consent forms do not â€Å"fully inform†¦research participants how their DNA may be used† argues law professor Hank Greely, and this communicat ion glitch â€Å"sows distrust† (Harmon, 2010). Researchers will be hard pressed to continue their work without the trust and participation of donors. DNA creates a new era of ethical challenges for business. Rather than continue to surreptitiously glean DNA via ignorance and inadequate consent forms, business communicators in the scientific industry need to open their process up to public scrutiny and become more transparent with their communication tools.

For  prà ªter, this is  prà ªt-. To this, a variety of endings are added to match both the tense of the sentence as well as the subject pronoun. For example, in the indicative mood,  je prà ªte  means I am loaning and  nous prà ªtions  means we loaned. Present Future Imperfect je prte prterai prtais tu prtes prteras prtais il prte prtera prtait nous prtons prterons prtions vous prtez prterez prtiez ils prtent prteront prtaient The Present Participle of  Prà ªter The  present participle  is easy to form as well. An -ant  ending is added to the stem of  prà ªter  to create the word  prà ªtant. Prà ªter  in the Compound Past Tense For the past tense, you can use the imperfect or the  passà © composà ©. The latter is a compound and requires you to use the  past participle  prà ªtà ©. First, however, you must conjugate the auxiliary verb  avoir  into the present tense. Its actually quite easy. I loaned is  jai prà ªtà ©Ã‚  and we loaned is  nous avons prà ªtà ©. More Simple Conjugations of  Prà ªter The forms of  prà ªter  above should be your top priority, but there may be times when youll need to use the verb in more subjective terms. For instance,  the subjunctive  calls the act of loaning into question while  the conditional  implies that its dependent on something else. The passà © simple  and  the imperfect subjunctive  are used less frequently. Youll likely only encounter them in formal French writing as they are both literary tenses. Subjunctive Conditional Pass Simple Imperfect Subjunctive je prte prterais prtai prtasse tu prtes prterais prtas prtasses il prte prterait prta prtt nous prtions prterions prtmes prtassions vous prtiez prteriez prttes prtassiez ils prtent prteraient prtrent prtassent The French imperative  may not be as useful for a word like  prà ªter, but its good to know anyway. The important rule here is that you dont need the subject pronoun: use  prà ªte  rather than  tu prà ªte. Imperative (tu) prte (nous) prtons (vous) prtez

College Skills for Homeschoolers

College Skills for Homeschoolers If your homeschooled student is planning to attend college, make sure he or she is not only prepared academically  but is also well-equipped with these seven skills. 1. Meeting deadlines One advantage homeschooled teens often have over their traditionally-schooled peers is that they have learned to effectively manage their time. By high school, most homeschooled teens are working independently, scheduling their day, and completing tasks with limited supervision. However, because homeschooling allows the flexibility to be self-paced, homeschooled teens may not have a great deal of experience meeting firm  deadlines. Encourage your student to use a planner or calendar to track deadlines. Teach him to break down long-term assignments, such as research papers, creating deadlines for each step. Assign short-term deadlines for other assignments, as well, such as â€Å"read three chapters by Friday.† Then, hold your student accountable for meeting these deadlines by imposing consequences, such as making up incomplete work on the weekend,  for missed deadlines. It can be difficult to follow through on such consequences when considering the flexibility that homeschooling offers, but a college professor isn’t going to be lenient with your teen when his poor planning causes him to miss assignment deadlines. 2. Taking notes Because most homeschooling parents don’t teach in a lecture style, many homeschooled kids haven’t had much  experience taking notes. Note-taking is a learned skill, so teach your students the basics and provide opportunities for them to practice. Tips for taking notes include: Listen for repeated words and phrases. If an instructor repeats something, it’s usually important.Listen for key words and phrases such as: first, second, because, for example, or in conclusion.Listen for names and dates.If the instructor writes something down, your student should write it down, too. Similarly, if a word, phrase, or definition is displayed on the board or screen, write it down.Teach your student to abbreviate, use symbols, and develop his own shorthand. He should use these tools to note key concepts and ideas rather than trying to write complete sentences.Instruct your student to go over notes at the conclusion of the lecture, adding in any important details that he remembers, making sure that what he wrote down makes sense to him, and clarifying anything that doesn’t. How to practice taking notes: If your student  attends a co-op, have him take notes during any lecture-style classes he takes.Ask your student to take notes while watching videos or online lessons.If you attend church, encourage your children to take notes during the sermon.Encourage your student to take notes as you read aloud. 3. Self-advocacy Because their primary teacher has always been a parent who knows and understands their needs, many homeschooled teens may find themselves lacking in self-advocacy skills. Self-advocacy means understanding your needs as relates to what is expected of you and learning how to express those needs to others. For example, if your homeschooled teen has dyslexia, he may need additional time to complete tests or in-class writing, a quiet room for testing, or leniency on grammar and spelling requirements for timed writing assignments. He needs to develop the skill to express those needs to professors in a clear, respectful manner. One way to help your teen develop self-advocacy skills is to expect him to practice them before graduation. If he takes classes outside of the home, such as a co-op or dual-enrollment setting, he needs to be the one to explain his needs to his teachers, not you. 4. Effective written communication skills Students should perfect a variety of written communication skills such as essays (both timed and untimed), email correspondence, and research papers. To prepare your students for college-level writing, consistently focus on the basics throughout high school until they become second nature. Make sure they’re using correct spelling, grammar, and punctuation. Don’t allow your students to use â€Å"text speak† in their written work or email communications. Because your students may need to communicate via email with professors, make sure they are familiar with proper email etiquette and know the correct form of address for their instructor (i.e. Dr., Mrs., Mr.). Assign a variety of writing assignments throughout high school such as: Compare and contrast essaysExpository writingDescriptive essaysNarrative essaysLetters – business and informalResearch papersCreative writing Consistently building basic written communication skills is vital to your students success in this area. 5. Personal responsibility for coursework Make sure  that your  teen is prepared for taking responsibility for his own schoolwork in college.  In addition to meeting deadlines, he’ll need to be able to  read and follow a course  syllabus, keep track of papers, and get himself out of bed and to class on time. The easiest way to prepare your student for this aspect of college life is to begin handing over the reins in middle school or early high school. Give your student an assignment sheet and hold him responsible for completing his assignments on time and adding key dates to his planner. Help him work out a system for keeping track of papers. (Three-ring binders, hanging file folders in a portable file box, and magazine holders are some good options.) Give him an alarm clock and expect him to get himself up and started by a mutually agreeable time each day. 6. Life management Your teen also needs to be prepared to handle personal tasks on his own such as  laundry, meal planning, grocery shopping, and  making appointments. As with teaching personal responsibility, life management skills are best taught by handing them over to your student during his high school years. Let your student do his own laundry and plan and prepare at least one meal each week, making a grocery list and shopping for needed items. (Sometimes it’s easier for one person to do the shopping, so it may not be practical for your teen to do the shopping, but he can add the needed ingredients to your grocery list.) Let  your older teens  make their  own doctor and dental appointments. Of course, you can still go with  them to the appointment, but some teens and young adults find it very intimidating to make that phone call. Let them get in the habit while you can still be nearby in case they have any questions or run into any problems. 7.Public speaking skills Public speaking consistently tops people’s list of fears. While some people never get over the fear of speaking to a group, most find that it becomes easier by practicing and mastering some basic public speaking skills, such as body language, eye contact, and avoiding words such as â€Å"uh,† â€Å"um,† â€Å"like,† and â€Å"you know.† If your student is part of a homeschool co-op, that can be an excellent source for public speaking practice. If not, check to see if you have a local Toastmaster’s Club in which your teen could get involved. You might also inquire to see if a member of the Toastmaster’s Club would teach a speech class for teens. Many students who are able to participate in such a class may be surprised to find it much more fun and less nerve-wracking than they had imagined. Make sure your homeschooled student is prepared for the rigors of college life by adding these vital skills to the academics youre already working on.

Since the time before, mediation of the distance between students, institutions together with the respective instructors have been determined by the most current technology utilized. Therefore, this script is of profound significance, as it would efficiently describe the evolution of distance education by presenting a research plan (Ludlow & Duff, 2009). Statement of the research problem This study aims at the identification of how distance education has evolved since its initiation. A number of sources addresses the same issue but from dissimilar perspectives. The application of distance education has been exploited in different parts of the globe, and this brings about the noted var iations. It is in noting the extent to which this form of education has evolved that identifying those factors necessary for such an occurrence would be easier. This study aims to reveal strategies that those involved ought to implement in enhancing efficacy required in this form of service delivery. The less developed and developing countries are deficient of the most current technology that is decidedly in use by the already developed states. These nations, especially those from Africa will be able to learn the concepts to adopt in order to initiate the distance education program. Therefore, the research question is; does enhancement in technology contribute towards the evolution of distance education? Review of the related literature The augmentation in the current technology has allowed WVU to utilize the technology aided distance education. According to a research conducted by numerous scholars, such a university has practiced distance education for more than two decades since 1980s (Ludlow & Duff, 2009). As this university initiated this process, it only endeavored to experiment whether it could work. However, their experimental attempts have resulted to the current expansive development in the use of this concept. The WVU distance education deals with offering programs on special education. The careful review of the literature designates an increase in the fraction of those enrolling in these programs each year. Additionally, it also depicts a rise in those completing such a program each academic year. During the introduction of this concept in the university, the majority of the participants were from within, but currently the participants emanate from all over the US. Moreover, the technology advancement has enabled individuals from all over the globe to participate in the distance learning activity. Literature indicates that the broadcast television; the most complicated technology of the day was used during the introduction of distance education pro grams. The development of courses that could be made available to students via the Public Broadcasting System (PBS) is what resulted to utilization of the television (Huett et al., 2008).

Autism - Essay Example This estimate have risen in recent years due to more awareness about Autism. Autism Spectrum Disorders (ASD), also known as Pervasive Developmental Disorders (PDD) along with the developmental disorders that fall under its umbrella are disorders are characterized by deficits in social and communication skills. The Autism Spectrum Disorders include: Asperger’s Syndrome, Pervasive Developmental Disorder – Not Otherwise Specified (PDD-NOS), Autism Disorder, Child Disintegrative Disorder and Rett Syndrome. In recent years, diagnoses of Autism have increased both in breadth and in depth. The increase in the prevalence of this developmental disorder to 1 in 88 children has become so alarming that many parents and practitioners have been more diligent in knowing more about it. Zalla et al. (2006) has encapsulated the definition of Autism as follows: It is â€Å"a complex developmental disorder characterised by severe difficulties in communication, social interactions, and executive functions. Social and communication disturbances are generally explained in terms of a defective neurocognitive mechanism responsible for the attribution of thoughts and feelings to oneself and to others† (p. 527). The many symptoms presented by individuals with Autism have been inconsistent in pointing to just one disorder that is why it had to be spread out to various disorders within the Autism spectrum. Although there are overlaps of symptoms, there are also categorical clusters that belong to one disorder that can be differentiated from another disorder. Under the umbrella of the Autism Spectrum Disorders (ASD) exists the highest functioning Pervasive Developmental Disorder (PDD) subtype called Asperger’s Syndrome (Kurita, Koyama & Osada, 2005). This is characterized by several deficits in age-appropriate social interactions and restricted,

MIcro-Economics Essay Example | Topics and Well Written Essays - 250 words

MIcro-Economics - Essay Example The first two months of the fourth quarter PAF was 95%. For the second and the third quarter the company recorded 83% and 85% respectively which was as a result of increased supply of coal from India. The steady supply of coal to meet demand will be facilitated by the signed agreement with India, to supply coal which will be fully completed by 2013. The terms price, demand and supply have their application in the attached article. Supply is the quantity of goods that are available to clients. In the attached article, thermal power corporation effectiveness depends on the amount of coal supplied. Demand is the aspiration to have something for instance, the power produced will be in great demand when the plant availability factor is low, because of scarcity. Price on the other hand is the amount paid back for goods or services provided (Glazer and Hirshleifer, 68). In this case price will stabilize if the supply of coal will be guaranteed as a result of signed pact. Coal therefore is an important natural resource for power production in the economy and to the people who consumes it. National Thermal Power Corporation or NTPC has shown higher capacity availability or plant availability factor during the first two months of the current quarter, indicating improved coal supply, according to data with the Central Electricity Authority. This augurs well for the state-run company considering that the previous two quarters were not so good for it and earnings declined due to lack of coal availability. This led to concerns over capacity availability of its thermal plants, which is directly linked to availability of coal. The plant availability factor or PAF of a plant is the maximum time that it can produce electricity over a given period and is mainly linked to fuel availability. Higher the availability of fuel, higher will be the PAF. NTPCs PAF for the first two months of the fourth quarter was 95%. The company witnessed PAF of 83% and 85% for the

In light of this potentially bleak future, Delaney’s character enables him to blend well within the society, at least temporarily. The cuts the image of a liberal individual with a clean driving record riding in a roadworthy Japanese car with unique registration details, before accidentally hitting Candido. My fear is that Delaney’s accident free driving record and his customized number plate, meant to attract the least of the public attention to his movements within the neighborhood seems to be compromised the moment his car rams Candido taking away his productivity. Delaney’s uncontrolled emotions also present a fearfully bleak future for him especially when he threateningly points a gun at Candido for causing a fire in the neighborhood. ... entially depicts the generosity of the owners of the food store and that of the donor customer towards members of the poor people in the neighborhood.

The family is infuriated by the wrath of nature witnessed in the killing of one of their two pets by a coyote. Boyle’s narration of their agony in response to the dog killing incident is seemingly more unbearable to the couple than the suffering of fellow illegal immigrants, most of who are like the Candidos, who struggle to secure basic needs in vain (37). Candido and his pregnant wife are left with nothing after t he robbery incident, a situation that prompts them to scavenge at fast food shops. Question # 4 The US government’s deployment of millions of illegal migrants to various sectors to provide casual labor such in local farms, homes, construction sites, and food joints, and care facilities presents a moral dilemma as most of them fled their native countries due to unbearable socio-economic and political conditions.

Customer Relationship Management Essay Example | Topics and Well Written Essays - 3000 words

Customer Relationship Management - Essay Example One of the key change agents that has in recent times been seen to have grown in critical importance for companies involves technology. Technology has played a major role in redefining nearly all aspects of business in the modern world (Bidgoli, 2010). It has been key in the facilitation of the gradual shift of power into the hands of the general consumer after moving it from the organization. The greatly empowered customers of the modern world are acutely aware of the immense power that they now wield. By utilizing the internet, customers are now able share information that helps bring them close to not only other customers but also to the organization. The shared feedback, information and various opinions are now generally available to one and all at a rate that can be viewed to be almost instantaneous. It is mainly due to this reason that it organizations cannot be able to ignore social media as a medium of communication (Flynn, 2012). Marketing managers have resulted to learn how to properly utilize this medium so as to be able to effectively manage the relationship that their companies and organizations happen to enjoy with their various customers, this is especially so in light of the fact that social media has proven to be both the bane as well as the boom to most organizations. Marketers are now using social networking to provide prompt customer redress. There is a lot of pressure being exerted on companies forcing them to constantly ensure that they are always on their guard due to the fact that customer reactions on the internet tend to generally happen on an instantaneous live basis. In the event that there happens to be any adverse feedback or shared opinion by a single individual dissatisfied customer, the opinion can quickly spread all over the internet and spearhead a campaign that can have the results of critically harming an organization or company. When used effectively, the internet can serve to help an organization to effectively build up it s customer relationship as well as sufficiently strengthen the existing relationship (Kurtz and Boone, 2010).

Discuss the impact of Christian Fundamentalism on American polotics Essay

Discuss the impact of Christian Fundamentalism on American polotics - Essay Example They are to be engaged with one another not only within the bond of civility but, much more importantly, within the bonds of the love of Christ. The truth of the gospel transcends our disagreements about all lesser truths. And it is by that truth that we are knit together in mutual dependence and accountability. By that truth, the church is enabled to be a zone of truth in a world of impassioned mendacities--not the least of all in the world of impassioned political mendacities. There was a time when political involvement by conservative Christians was seen as a worldly or even sinful activity, now, political celibacy, if you will, is considered a dereliction of Christian responsibility. This mega-shift in perception has not been a recent phenomenon but evolved with time. During late 19th century until 1920s, the influence of conservatives collapsed. However, after 1950s, it revived miraculously due to contemporary political situation and worked its way up to reach a stage today that most of battles in the world are being portrayed as the ones with the evil, and there seems to be public support for many such aggressions which have almost divided this world into "with us or not with us". Religion is the most dangerous energy source known to humankind. ... The history, worldwide, of religion-fueled hate, killing, and oppression is staggering." - Eugene Peterson (from the introduction to the book of Amos in the Bible paraphrase The Message) Within the span of one generation, between the 1890s and the 1930s, the extraordinary influence of evangelicalism in the public sphere of American culture collapsed. Not only did the cultural opinion makers desert evangelicalism, even many leaders of major Protestant denominations attempted to tone down the offenses to modern sensibilities of a Bible filled with miracles and a gospel that proclaimed human salvation from eternal damnation only through Christ's atoning work on the cross. Therefore, making the connections between faith and politics in the late 1970s was quite novel at the time and controversial among conservative Protestants, especially fundamentalists. It is often argued that fear of religious conservative culture and not loss of socio-economic status led to political organisation of Protestant Christians during 1960s and later. Another reason for their organisation was they were not getting their due recognition in affairs of the state. Another section points out that political activism was spearheaded by the development of so called unethical and immoral cultures in the society. What stirred religious conservatives most was a sense that Supreme Court decisions were giving power to the opponents of traditional Christian values. The Court banned state sponsored prayer and Bible reading in the schools (Engel v. Vitale, 1962), legalized abortion (Roe v. Wade, 1973), and allowed for more government regulation in private Christian schools (Lemon v. Kurtzman, 1971). As a result, they became engaged in

Benefits of Learning in a Diverse Environment in Toronto Essay Example for Free

Benefits of Learning in a Diverse Environment in Toronto Essay Toronto,Canada has been one of the most multicultural cities in the world and has attracted thousands of immigrants and foreign students each year mostly from Asian and European countries (Toronto, 2007) Due to the popularity of the city to foreigners as well as the prestigious schools it has such as the University of Toronto and the York University, students from different parts of the world have been attracted to study in the city. Universities have been offering a diverse learning environment, offering curriculum, facilities, and learning resources including professors and instructors that address the needs of and accommodate the growing number of foreign students and immigrants in Toronto. A diverse learning environment offers various benefits to students regardless of culture and nationality. First, it introduces me to different cultures and race, making students like me become aware of various cultures and beliefs. Having the awareness of different cultures of people in Toronto can improve my interpersonal and communication skills. â€Å"Hanging around people of different culture develop the students ability to understand the ideas and feelings of others, which in later life makes them, more likely to live in racially diverse communities, maintain friendships with people of different races and able to function more effectively in an increasingly diverse workplace† (Haas, 1999). From this view, a diverse learning environment therefore can eliminate or reduce racism and racist attitudes towards the minority groups. It also can also prepare me to adapt to a diverse environment in case I have to work or migrate to other country particularly in Asian and European countries especially now that the level of globalisation is increasing. A diverse learning environment can also improve my ability of working in a team since in universities, there are particular activities that needed group efforts and diverse ideas that can result to a more comprehensive outcome, providing me various ideas that could have never been available if not because of my foreign classmates and friends and even professors. On the other hand, there are still some people who are not open-minded and are not interested in learning about other cultures due to their very racist attitudes. A diverse learning environment with students or professors like these people can negatively affect some foreign students and students from minority groups, making them feel discriminated and unwelcome to such learning environment that may lessen their interest in studying or acquainting with students of different nationalities. However, in Toronto, it seems not much of a problem because foreigners and immigrants have long been welcomed in the city.

Types Of Database Management Systems

Types Of Database Management Systems As we know databases are being used more than ever before to store and to access information. Due to the ease of maintenance and outstanding performance of databases, the growth of database technologies has been increasing rapidly. Moreover DBMS had thrived over World Wide Web. Different web-applications are retrieving the stored data and the answers are displayed in a formatted form using web languages like XML. This essay talks about the different Data Models for databases, and discusses their relative strengths and weaknesses. I will present the most common approaches for data modelling that are used by DBMSs (RDBMS, OODBMS, ORDBMS and XML ) giving a quick introduction to each of them we will compares and contrasts the approach treating them comparatively. DATA MODELS Database Model can be categorized according to the data structures and operators they present to the user. (Bloor, 2003) (1) E-R Model (2) Hierarchical Data Model (3) Network Data Mode (4) Semi Structured Data Model (5) Relational Data Model (RDBMS) (6) Object Oriented Data Model (OODBMS) (7) Object Relational Data Model (ORDBMS) (8) Semi-structured data (XML) Among all data models mentioned below, relational model followed by object oriented and object relational models enjoyed most popularity, we are going to define one by one and at the same time we are going to show their advantages and disadvantages. RELATIONAL DATABASE MANAGEMENT SYSTEM (RDBMS) In RDBMS, all the data is in the form of simple columns and rows in a table. Each table is an individual and independent entity and we need not to use any physical pointers or physical links to connect the entities like what we used to have in network and hierarchical models. All data is maintained in the form of tables consisting of rows and columns. Data in two tables is related through common columns. Operators are provided for operating on rows in tables. Because of this, querying becomes very easy. This was one of the main reasons for the relational model to become more popular with programmers. The RDBMS structures data into relations (tables) which form a two-dimensional representation of the data into rows and columns. A relation contains tuples (rows) and each tuple represents a distinct record in the table. A tuple consists of a set of unorganized attributes (columns) providing detail for the record. Rows are assigned a unique identifier, also known as a primary key, by which the record can be accessed, manipulated, and referenced by other tables or applications. Columns store the attributes of a record, more commonly known as fields, and each attribute is assigned a data type. Structured Query Language (SQL) is identified and accepted as the standard query language and transaction mechanism for RDBMS. SQL queries can be used to access and return data from tables, define records and their attributes, and to view data from multiple tables through operations such as a join.(Dolk, 1998) Two of the most popular examples of RDBMS currently on the market are Oracle and Microsoft Access. Advantages of RDBMS In RDBMS system, the tables are simple, data is easier to understand and communicate with others. RDBMS is flexible, users do not have to use predefined keys to input information. Automatic optimization of searching is possible in RDBMS Structure Query language (SQL) is easier to learn and implement. It supports large and very large databases. RDBMS are more productive because SQL is easier to learn. This allows users to spend more time inputting instead of learning. Disadvantages RDBMS Not much efficient and effective integrated support. Do not have enough storage area to handle data such as images, digital and audio/video. Relational tables are flat and do not provide good support for nested structures, such as sets and arrays. And also certain kinds of relationships, such as sub-typing between database objects are hard to represent in this model. RDBMS technology did not take advantage of Object oriented programming concept, which is very popular because of its approach. All the data must be in the form of tables where relationships between entities are defined by values. 2.2 OBJECT ORIENTED DATABASE MANAGEMENT SYSTEM (OODBMS) As you are aware, web and Internet usage is rapidly increasing nowadays. To meet the challenge of the web and to overcome the limitations of RDBMS, OODBMS was developed. OODBMS stands for Object oriented database management system, which we can define as; it is a combination of Object Oriented Programming and Relational Database Management System. (Fong, 1997) Inheritances, data encapsulation, object identity, and polymorphism are the main characteristics of object-oriented programming. By defining new objects, we can develop solutions to complex problems in inheritance. Objects are related and shared within a network and have an independent identity. The object identity (OID) works behind the scenes to ensure the uniqueness of the tuples, which is invisible to the users. Moreover, no limitations are required on the values. If we take the same thing in RDBMS, then we have to worry about uniquely identifying tuples by their values and making sure that no two tuples have the same primary key values. On the other hand, polymorphism and dynamic binding are useful to create objects to provide solutions to the complex ones and to avoid coding for every object. These objects may be transient or persistent. By persistent object we mean the permanent object stored inside the database to survive the execution of data process and in order to eventually reuse it in another process. OODB deals with these objects in a uniform manner. To create, update, delete or to retrieve the persistent data, data definition language and data manipulation languages are important in OODBMS. These languages are also useful to define a database, including creating, altering and dropping tables and to ensure the integrity constraints in tables. Object Query Language (OQL) is the standard query language for OODBMS. OQL uses syntax similar to SQL and is rarely used since the basic functionality of queries in intrinsic to object-oriented programming languages.(Chaterjee, 2005) Advantages of OODBMS More semantic information Support for complex objects Extensibility of data types May improve performance with efficient caching Versioning Reusability Inheritance speeds development and application Potential to integrate DBMSs into single environment Disadvantages OODBMS Strong opposition from the established RDBMSs Lack of theoretical foundation Throwback to old pointer systems Lack of standard ad hoc query language Lack of business data design and management tools Steep learning curve Low market presence Lack of compatibility between different OODBMSs 2.3 OBJECT RELATIONAL DATABASE MANAGEMENT SYSTEM (ORDBMS) Object Relational Database Management System (ORDBMS) is an extended development of existing relational database system. To overcome the certain limitations and to increase the performance level, and to achieve the benefits of relational model and object model, ORDBMS technology evolved by combining the relational databases and object oriented concepts. We can incorporate our custom data types, functions, operators and methods with the database and we can store images, geographical information and multimedia objects such as audio and video, it allows us to raise the level of abstraction at which we want to view the problem domain. In ORDBMS limited support of object oriented features, mostly to new data types. Moreover, it supports abstract data types (ADTs) and complex relationships. ORDBMSs have the same query centric approach to data management as we have in RDBMS. Through declarative SQL statements, we can handle the data access and there is no procedural or object-at-a-time, navigational interface. ORDBMS allows us to continue using our existing systems, without having to make major changes. In simple words, we can say that ORDBMSs synthesize the features of RDBMSs with the best ideas of OODBMSs. (Cigler, 1999) Advantages of ORDBMS Ability to query complex applications and ability to handle large and complex applications Reduced Network Traffic queries and complex instructions can be executed on the server (as opposed to clients) Application and Query Performance Parallel server technology can be employed Software Maintenance data and methods are stored on the server and makes maintenance easier Integrated Data and Transaction Management. The database engine handles all transaction integrity, backup, etc., issues Disadvantages of ORDBMS Modeling and processing support of complex objects and their versions, large objects, semantic-rich relationships, etc. is only rudimentary or even missing in current ORDBMSs ORDBMSs have to be complemented by adequate client-side data management and long-running design transactions encapsulating the client processing model, in order to provide satisfactory support for technical applications Low performance in web applications 2.4 XML To understand XML is important to understand its roots as a markup language documents. The term trademark is any element in a document that it is not intended to be part of the printed output.. In an electronic document processing a markup language is a formal description of what is contained in the document, which part is brand and what the brand stands for. As well as database systems evolved from the physical processing of files to provide a logical isolation, the markup language specification developed from the instructions indicating how to print parts of the document for the contents.. Such functional brand allows the document to have different formats in different situations. It also helps different parts of a long document, or different pages in a large Web site, have a uniform format. The brand works also helps automatic extraction of key parts of the documents. For the family of markup languages in which includes XML makes the form of tags enclosed in angle brackets . Labels are used in pairs, and defining the beginning and end of the portion of document to which the label refers. Compared to storing data in a database, the XML representation may seem inefficient, since tag names are repeated throughout the document. However, despite this disadvantage, an XML representation has significant advantages when used for data exchange, for example, part of a message. First, the presence of tags makes the message is self documenting, Second, the document format is not rigid. The ability to recognize and ignore the unexpected labels allows the format of the data evolve over time without invalidating existing applications. Finally, since the XML format is widely accepted there are a variety of tools available to aid processing, including search software and database tools. As is the dominant language SQL to query relational data in XML is becoming the dominant format for data exchange. Where Object Databases have Object Query Language (OQL), XML Databases have XQuery which is a W3C standard. XQuery covers the major functionality from former language proposals like XML-QL, XQL, OQL and the SQL standard. (Dodds, 2010) Advantages of XML Heterogeneity: Where each record can contain different data fields. Extensibility: Where new types of data can be added at will and dont need to be determined in advance. Flexibility: Where data fields can vary in size and configuration from instance to instance. It often requires no or little work during XML Schema evolution. Disadvantages of XML Mapping your XML format to a relational schema leads to a large number of tables. Your XML Schema is highly variable or tends to change over time. Annotating an XML Schema can be complex, if the schema itself is complex. Using XML as your database will work fine as long as your datasets stay relatively small. Once your data grows to the point where it will not all fit in memory, you will probably start seeing serious performance degradation. RDBMS, OBJECT ORIENTED and XML DATA MODELS COMPARATION AND CONTRAST 3.1 COMPARING RDBMS and OODBMS Relational databases have as their objective to ensure data independence. Normalized data are separated from processing and the processing corresponding to satisfying informational requirements need not be totally pre-defined, thus accepting ad-hoc requirements too. Object oriented databases have as their main objective encapsulation, being stored together with the data and the methods. They are inseparable. It is said that we have to do with an independence of classes and not with an independence of data. An OODBMS and not an RDBMS is needed when in the reference applications we have to do with complex data. The object oriented database markets will continue to develop, but they will still (represent) only a fraction of the traditional databases. It is appreciated that RDMSs hold the largest part of the largest part of the data-bases. But the prospect is that they will still co-exist for a long time future with the OODBS 3.2 COMPARING RDBMS with the ORDBMS An ORDBMS is a relational DBMS with SQL3 extensions. SQL3 extensions include: row types, user-defined types and user-defined routines, polymorphism, inheritance, reference types and object identity, collection types (ARRAYs), new language constructs that make SQL computationally complete, triggers and support for language objects. A RDBMS is characterized by simplicity and increased stability as compared to an ORDBMS, and this fact confers it the quality of being easily used. A mechanism to plug in any user defined index structure provides the highest level of flexibility. Both DBMSs are characterized by simplicity of development owing to the fact that it provides independence of data from applications good for simple relationships. RDBMS is a mature software product while ORDBMS is an immature product (extensions are new, thy are still being de-fined and are relatively unproven. 3.3 COMPARING OODBMS with ORDBMS OODBMSs and ORDBMSs both support user-defined ADTs, structured types, object identity and reference types, and in-heritance; They both support a query language for manipulating collection types; ORDBMSs support an extended form of SQL, and OODBMSs support ODL/OQL; ORDBMSs consciously try to add OODBMS features to an RDBMS, and OODBMS in their turn have developed query languages based on relational query languages; Both OODBMSs and ORDBMSs provide DBMS functionality such as concurrency control and recovery; OODBMSs try to add DBMS functionality to a programming language, whereas ORDBMSs try to add richer data types to a relational DBMS 3.4 XML AND OODBMS XML data does not need to be instantiated as objects in OO code in order to be processed and presented to users. Instead, XML data can be decorated and enriched with tags, and these tags can be processed and understood XML Schema may seem very OO-like at the first glance, but in fact it is missing some important OO-like capabilities. For instance, there is no element-level polymorphism. OO programming is intended to optimize the programmer, not the value or usefulness of the data. XML, on the other hand, is intended to optimize the data. If you use XQuery with XML for all data representations, and never write any OO code, you optimize the datas usefulness and accessibility, because data in XML can be accessed and processed by almost any software on the market. Data in an object database cant. 3.5 XML AND RDBMS. Many developers in the search for greater flexibility think their options are limited to the relational model. Some think that store everything in XML format, reducing the difference between object-oriented applications and relational databases. The relational model is limited, limits are needed to meet the data integrity. In XML, the data structure is more relaxed but it exists. XML schemas are very volatile business, but very stable in other situations. Not being able to find a structure that adapts to a problem of a company, does not mean that this structure does not exist. XML model should be used if the data are scarce, this is to have many unknowns, or columns (fields) do not apply to all rows (records). The solution to this problem is to introduce subtypes or implement an open scheme in the relational model. Introducing subtypes can lead to many new tables, with an open schema solution in the relational model can lead to dynamic and complex SQL statements. An XML-based solution might be best. Conclusions From my point of view the future of Internet-based business applications is dependent on their ability to exchange information between different data stores or database systems. Every day more data such as images, digital and audio/video data types need to be transported from one application to another one through the Net. Because relational databases store data as two-dimensional tables, they are not ideally suited for data manipulation, since data itself may be expressed in the form of complex structures, object-oriented languages appears to be much more efficient, expressing data as objects with rich features including inheritance, polymorphism and encapsulation for maintaining relationships between objects.. However, large amounts of data across the world are still typically stored in RDBMS; when the data from an object-oriented world is persisted in a two-dimensional table format; hierarchical relationships between objects arent preserved, making persistence and recovery of data a complex task. The addition of an OODBMS in the RDBMS environment may require modifications in the existing databases in order to enable communication and data access among them. Moreover, the retrieval and search in many cases wouldnt be efficient as we expect. As we have seen in my document XMLs express purpose is to provide a mechanism for the expression of data structures so it might be a big opportunity to unify the technology providing the bridge between these two kinds of persistence systems and makes it unnecessary for example object and relational databases solutions of direct conversion between one another. Here we realise that despite the differences, the RDBMS and OODBMS could live in agreement whit XML and offer their advantages for todays e-business solutions.

The Prince by Niccolo Machiavelli Essay examples -- Papers Leader Lead

The Prince by Niccolo Machiavelli The Prince by Niccolà ² Machiavelli was written in the year 1513 A.C.E. in Italy during a time in which his views were greatly detested by others. They were so hated that he was exiled from his own country for writing them. When hearing this, one must ask oneself, what kinds of views did Machiavelli have so that his own country would cast him out? His ideas, though written very complexly, were very simple. One must gain success and to do so, any means were justifiable. He wrote his ideas in a lengthy letter to prince of Italy, Lorenzo de’ Medici. He gave him advice that was supported by history and what he thought were the precise makings of an excellent leader. That advice was both excellent and awful. In the document, The Prince, Machiavelli writes about many characteristics that a good prince should have. The five main characteristics are as followed: (1) A price must have no other thought in mind than war and how to pursue it (Machiavelli, 279), (2) a price must be liberal, rather than generous (Machiavelli, 282), (3) a good prince should be ...

Acetone Research Paper

Acetone is an extremely popular solvent that is used in rubber, resin, plastics, lacquers, varnishes, and rubber cements. It is also used in the creation of fats, oils, and waxes where is a primary component. Acetone has many uses in modern technology including those that relate to the medical field and various domestic uses. It is a very important organic compound found in everyday life, but it is also a toxin and can be an extremely dangerous environmental pollutant.Acetone has many valuable uses in modern life and many American companies use Acetone as one of their key components to many household items. There are many ways that Acetone is used everyday. One of the most common purposes of Acetone and one of its most well known, is the use of Acetone as a primary ingredient in nail polish remover. Acetone is also commonly found in the use of artist and craft makers. Similar to nail polish remover, Acetone can be used in other artistic agents. A common use of Acetone is for the remo val of residues off metals, glass, and porcelain.It also commonly used as a remover of superglue. Acetone is also used greatly by make-up artists in order for them to easily remove skin glues and adhesives from fake moustaches and wig materials. There have been many claims that Acetone is dangerous to the humans due to concentrated exposure from these very sources, which has been proven true. Concentrated exposure has been proven on numerous occasions to have an adverse affect upon humans. There are many negative health effects from exposure to Acetone, and each one differs from different types of exposure.According to the National Pesticide Information, there four ways exposure to Acetone can occur. The first is through inhalation, which can cause the symptoms of confusion, coughing, dizziness, headaches, sore throat, and unconsciousness. The second form of exposure is through direct contact with the skin. This can cause dry skin and rashes. The third way is exposure to the eyes, w hich can cause redness, irritation, pain, blurred vision, and possible cornea damage. The fourth and final way of exposure is from ingestion.Ingestion can cause the same symptoms as inhalation as well as the possibility of nausea and vomiting. Clearly, there are many health risks to the exposure of Acetone. Along with these mentioned symptoms, there have also been studies that have shown possible dangerous and long-term health risks to concentrated exposure. These studies have shown that concentrated exposure has lead to fainting and long-term effects have shown to be kidney, liver, and nerve damages. There have also been studies that support that birth defects and male reproductive problems were also health concerns due to long-term exposure.While there appear to many health risks due to exposure of Acetone, Acetone itself is actually considered a relatively safe compound if used properly. According to The National Health and Medical Research Council, Acetone has been rates General ly Recognized as Safe. Many manufacturing companies see Acetone as safe is exposure is minuscule and to the minimum. Because of this, Acetone can be found in beverages, pastries, desserts, processed and unprocessed foods, and is also found in a variety cosmetic and beauty products.While Acetone is considered to be only slightly hazardous to many manufacturing companies, it is important to recognize what Acetone truly is. Allow Acetone exhibits relatively low dangerous properties, it can deadly when properly exposed. Acetone is still considered a toxic chemical and can cause devastating destruction if exposed as an environmental pollutant. While Acetone does not pose much threat to humans in moderate doses, just slight exposure to the environment can completely upset an ecosystem. When exposed to the environment, Acetone is typically found polluting groundwater areas.This is due to Acetone’s high water solubility in water. In water, Acetone can cause great health defects to wi ldlife. Because common groundwater would be the home and drinking source of many organisms, Acetone pollution can quickly cause health problems and sicknesses in a surrounding ecosystem. The most common wildlife affected by Acetone are those that are water based. Studies have shown that fish and amphibians exposed to high levels of Acetone have numerous internal health defects, which include deformation to the reproductive organs.Acetone has also been shown to cause a risk of oxygen depletion in these aquatic areas. Acetone is also known to evaporate relatively quickly, which allows it to dissipate and spread into the atmosphere even when properly disposed of. Acetone is one of the most used solvents in the world and is found in numerous consumer products. From an economic standpoint, Acetone is found to be a relatively safe chemical. However studies have shown that exposure to Acetone can lead to adverse effects in humans. Acetone has also been shown to be an extremely deadly envir onmental pollutant, which can destroy ecosystems.
