Midterm - Essay Example This means that people and business organizations are on a continuous journey that requires them to experience various processes and practices consciously or unconsciously. In this case, business organizations are expected to be abreast of the changing factors that can affect their profitability and other management aspects. This paper examines the concept of change and how it can be used by organizations to create and enhance their effective performance and success. It focuses on a Chinese Company, Alibaba Holdings, which has navigated its path to reach its current levels of excellence in business performance. The company has recently been listed on the New York Stock exchange in a bid to remain competitive and enhance its market position (Lianna, Jessica & Ryan, 2014). Currently, the pace by which globalization has been taking toll on businesses has quickened tremendously. Business executives and owners have been increasing their call for flexibility, agility and innovativeness from various business functions (Robertson, 2006). This development is aimed at positioning businesses strategically to tackle the rising challenges in competition and other factors in the external and internal environment. Amidst all these persistent calls, one thing has often been largely ignored, that is, organizations are creatively designed in order to search for competitive advantages that are sustainable. In addition, the fact that stability in business practices is just not desirable and effective, but attainable as well, has been an issue buried deeply in managerial psyche, but has been bolstered by periods of practice and theory (Christopher & Edward, 2006). It is important to understand that the popularity that is often associated with efforts for process improvement that range from overall quality management to various kinds of sigma provides are enough evidence for

Securing America and Protecting Civil Liberties Essay - 1
Securing America and Protecting Civil Liberties - Essay Example The liberties held so dear to the Americans was changed in number of ways where the law enforcements agencies had the right of conducting the searches of the homes and offices without a notice in advance or there were regular monitoring of the computers, email messages and text messages so that the clients can be eaves dropped on and so on. The clash between the civil liberties and the national security had taken place a number of times where the restrictive laws have played an important role to abridge the gap that exists between the two. In response to the terrorist attacks of 9/11, on September 14, 2001, Geroge W.Bush declared the state of emergency which gave him the right to invoke his presidential rights passing the Patriot Act which not only centralized the law enforcement powers to the Justice Department, but also gave CIA the oversight of the gathering of the domestic intelligence, and the rights of the citizens and non residents as stated in the constitution were disregarde d. After the terrorist attacks, the Patriot Act has played a very important role where several have debated over how ethical or unethical the Act was. The Department of Justice wanted to do everything possible to ensure that the terrorist attacks in the future can be prevented and therefore Patriot Act in this respect played a very important but at the same time a very controversial role. There were a number of operations carried out so that the Americans could be protected but in the aim of protecting the innocent America, their way of life was put in jeopardy and the true essence of the America life style was lost. It has been debated a couple of times that the first amendment, fourth amendment have been affected and eroded by the USA Patriot Act which gave birth to a large number of legislative changes , where most importantly the investigative powers of the law enforcement agencies was increased. Amendment 1 stated: ââ¬Å"Congress shall make no law respecting an establishment o f religion, or prohibiting the free exercise thereof; or abridging the freedom of speech, or of the press, or the right of the people peaceably to assemble, and to petition the Government for a redress of grievances.â⬠(Bill of Rights and Later Amendments ushistory.org) Amendment 2 stated: ââ¬Å"The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no Warrants shall issue, but upon probable cause, supported by Oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized.â⬠(Bill of Rights and Later Amendments ushistory.org) The American Government made changes to the surveillance laws and gave the law enforcement authorities to not only spy on the citizens but also limit the checks on those powers such as public accountability etc. ââ¬Å"The USA Patriot Act permits seizure of voice mail pursuant to a search warrant , al lows victims of computer trespassing to invite law enforcement to monitor attacks on their computers without needing a court order.â⬠(Etzioni, A., & Marsh, J. H. (2003). Rights vs. public safety after 9/11: America in the age of terrorism. Lanham, Md: Rowman & Littlefield) Initially when America declared the war on terrorism, it was

Evidence Based Medicine Essay Example | Topics and Well Written Essays - 4000 words
Evidence Based Medicine - Essay Example They point out that the journals have a scholarly rather than practical approach to solving clinical matters at hand, (Department of Medical Sociology, 1998). With the aim of exploring the barriers that GPs face in the implementation of EBM in routine clinical work and identifying possible strategies in its integration in daily work; studies have been carried out to explore this phenomenon in various parts of the world. One such study was carried out by Kenneth S Yew (MD) and Alfred Reid (MA) from the Uniformed Services University and The University of North Carolina respectively, (Physicians for the twenty-first century, 1984). They held focus group discussions with 10 General Practitioners (GPs) in public and private practice in the randomly selected from Charlotte and its environs. The aim was to find out the long term effects of teaching Critical Appraisal and Evidence Based Medicine on practicing physicians. Their goal was to explore ways in which the long-term outcomes of an integrated CA/EMB curriculum could be evaluated using a qualitative analysis of self-reported use of the two skills in everyday medical practice. Their secondary goal was to find out barriers to CA/EMB application. Reinhold Wentz has estimated that 50,000 physicians, students and health care workers receive training each year, Wentz R. (2001). P Participants mentioned that they had found the approach they used in residency was still helpful to them in situations that they faced as full time GPs, but only in circumstances that allowed them to search and reflect. However, where they immediately had patients to deal with, they preferred to rely on their own intuition and experience. A good number of them expressed guilt that they were not applying the EBM methods even though they were fully aware of how useful these were. Consequently, when it came to the question of barriers, almost all those interviewed were unanimous that time was the main culprit. Some pointed out that where they had to choose between attending to patients and making references, they often found themselves opting for the former. About 30% of the respondents said that they applied the EBM methods regularly but not when resolving an immediate clinical question. Conversely, all the participants were also unanimous on the importance of attending CME courses and as a matter of fact they did attend them. They were sure that they valued keeping up to date as it gave them immense satisfaction. 2% of the participants identified CME as their primary self-learning method. All reported that they regularly read journals while 5% read their specialty society journal regularly. About half also identified teaching and questions arising from patients as their main incentive for learning. Apart from luck of time, the participants also mentioned that the nature of their work kept them constantly under pressure to produce clinically. The majority expressed frustration at this constant pressure to perform, a common sentiment among GPs. Barnett SH et al (2000). Unfortunately, none of them associated performing in their duties with applying EBM since they mostly regarded this as a drawback on quick efficiency. Yet they all felt that they could do their work muc h better if they found the space in their punishing schedules to make references a little more and keep up to date. They figured

ISLAMIC JURISPRUDENCE Essay Example | Topics and Well Written Essays - 3500 words
ISLAMIC JURISPRUDENCE - Essay Example by the UK, US and its coalition members was seen by the Arab media and religious leaders as an initiative to annihilate the Iraq to safeguard the Israel, to control its oil fields and to foster animosity between shiis and Sunnis. Muslim leaders disregarded the claim of USA that war in Iraq was to put an end to use of WMD by Saddam, to severe Iraqââ¬â¢s connections with the Al-Qaeda, to declare Iraq as a democracy, to castigate Iraq for failure to comply with UNOââ¬â¢s Security Council resolutions and to throw out an unruly dictator1 . Information collection inside Iraq is seen as a most challenging job as Saddam is the most enigmatic and tyrannical leader in the world2. As per Dr Gary Samore, the record of gathering information by Western intelligence agencies on Iraqs various weapons programmes is very meagre3. The decision to go to war in Iraq was based on human rights abuses and its weaponsââ¬â¢ programmes. UK war on Iraq was based upon current and serious threatâ⬠from Iraqââ¬â¢s weapons of mass destruction (WMD). The prime objective remains to rid Iraq of its weapons of mass destruction and their associated Programmes and means of delivery, including prohibited ballistic missiles, as set out in the relevant United Nations Security Resolutions (UNSCRs). On 24 September 2002, a dossier was published by the UK Government containing its evaluation of Iraqââ¬â¢s programmes to build up WMD (the ââ¬ËSeptember Dossierââ¬â¢). The Governmentââ¬â¢s dossier of September 2002 sets out in detail Iraqââ¬â¢s history of production, use and concealment of chemical and biological weapons, and its pursuit of a nuclear weapons programme. UNSCOMââ¬â¢s final report of 1999 the then Executive Chairman concluded that Iraq continued to hide substantial information about prohibited p rogrammes and probably continued to develop them. The Iraqi chemical industry could produce mustard gas almost immediately, and limited amounts of nerve gas within months4. As early as in 1980s, it has been suspected that

Chemistry IA design format Essay 1.0.0- Introduction 1.0.1- Focus Question- If the mass of magnesium reacted with hydrochloric acid is changed will the temperature of the solution increase and the total mass decrease. 1.0.2- Hypothesis- If the mass of magnesium that is reacted with hydrochloric acid is changed the temperature of the solution will increase and the total mass will decrease. 1.0.3- Theory- The reaction between magnesium and hydrochloric reaction is written as follows, Mg(s)+ 2HCL (aq) (MgCl2(aq)+H2 (g) (Ng, 2008, pg 1). This reaction goes through two distinct changes that both have an effect on the energy change in the reaction. Enthalpy refers to changes in energy in a compound (Assut, 2008, pg 1). Two distinct changes can occur. An endothermic change occurs when the energy being absorbed is grater then the energy being released whereas and exothermic change is when the energy being released is greater than the energy being absorbed. Energy is absorbed when bonds are broken and energy is released when they are formed (Newton, 2008, pg1). Energy change cannot be directly measured. However energy change affects the physical force of heat. Therefore a heat change is indicative of an energy change. If the heat increase in the solution the change will be exothermic and if the heat decreases the reaction will be endothermic. In respects to the formula Magnesium forms an ionic bond with chlorine to form the salt magnesium chloride. When this bond is formed energy is released in the form of an endothermic change, this energy drop would be quite small however because the bond is ionic and does not take much energy to create since magnesium and chorine bond easily. However the second change is that hydrogen breaks off from chlorine in the hydrochloric acid and hydrogen is released as a gas. The breaking of bonds would absorb energy therefore forming an exothermic reaction. Hydrogen and chorine however form a very strong covalent bond. Covalent bonds form between atoms with similar electronegative forces and are there for take a lot of energy to break ( Anissimov, 2008, pg 1) Since the endothermic change is weak and the exothermic change is strong it can be predicted that the overall change will be exothermic and therefore the solution will heat up. Temperature change in a chemical reaction can be measured with a device known as a calorimeter. A calorimeter measures the heat of the solution before the reaction has occurred and then again after the reactant has been added (Whel, 2008, pg 1). These two values can be mathematically manipulated to find the relative change in temperature. If two of the same substance have different masses it means there is more of the one substance. In a mass of a substance there is a certain amount of material that can be reacted. By increasing mass the amount of substance that may be reacted increases. Therefore if mass increased the amount that of substance reacted will increase as well providing there is enough of the reactant. This will in turn increase the energy change. Also if more of the substance reacts with the reactant more of the reactant will be used up. This means that if the magnesium is increased there will be more reaction with hydrochloric acid; this means that more hydrogen will be released as gas and the total mass of the solution will decrease. Henceforth the change in heat should be greater if their entire solution is lighter as more of the hydrochloric acid has been reacted and hydrogen lost as a gas. How the reaction works (Figure 1) Mg(s)+ 2HCL (aq) (MgCl2(aq)+H2 (g) 1.1.0- Controlling variables 1.1.1- Variables (Table 1) Variable Type of variable Method for control Mass of magnesium Independent Mass will change for each sample, sample range will be 2g, 4g, 6g, 8g and 10g Heat change Dependent This will be calculated by subtracting the final heat of the solution by the initial heat of the solution. The data will be gathered by using a calorimeter Change in mass in solution Dependent This will be calculated by measuring the weight of the solution and subtracting the weight of the calorimeter and the magnesium. The original mass not including calorimeter and the magnesium will then be subtracted by this value to mind the change of mass in the solution. Initial temperature Controlled The temperature of the solution will be heated to 25c and the reaction started immediately. External temperature Controlled The room temperature will be controlled at 24c Volume of hydrochloric acid Controlled The volume of hydrochloric acid will be 40mls per sample. Measuring apparatus Controlled A 50ml calorimeter with electronic thermometer and a scale with milligram accuracy. Time of experiment Controlled The experiment will be ended when reaction is fully complete and reaction will be given 10 seconds to calibrate before results are taken Replications Controlled Standard 5 replications of each sample will be performed. 1.1.2- Control used in comparison- The reacted samples will be compared against hydrochloric acid with no magnesium that is also 25 degrees Celsius. Since the temperature remains constant there should be no energy or mass change, this would mean that on a graph this would represent a straight line which others samples with energy changes (heat changes) could be compared to.

Bis {N- (2, 4- dinitro- phenyl) N- (3- phenyl- allylidene)- hydrazine} Uranyl (VI) nitrate prepared r Keywords: Bis {N- (2, 4- dinitro- phenyl) N- (3- phenyl- allylidene)- hydrazine} Uranyl (VI) nitrate, synthesis, thermal analysis, FT-IR and UVââ¬âVisible spectroscopy, Schiff bases. Introduction A Schiff base, named after Hugo Schiff, is a compound with a functional group that contains a carbonnitrogen double bond with the nitrogen atom connected to an aryl or alkyl group, not hydrogen. Complexes of uranyl with nitrogen ligand are of considerable interest due to broad spectrum of biological activities. Formation of transition metal complexes with ligands of uranyl family are important because this ligands connected with various modes to the electron-rich and electron-poor metals. uranyl containing ligands are known to form stable complexes with class b metal ions, such as gold (I). Nitrogen-containing ligands is an important factor in the development of coordination chemistry such as Schiff bases and their metal complexes. and biochemically relevant studies of metal complexes [1]. A group of nitrogen-containing ligands represent a wide range of biological activities and this class of ligands known as pyrimidine system. These groups are valuable ligands in chemistry and on th e other hand have a huge impact on biological properties. For example, a furopyrimidine ring according to the isoelectric contact with purine, is highly regarded. Other uses are as a pesticide and medicine such as antifolates, antimalarials, and antivirus and other hand, protects against radiation. Recently, it has been found that the fluoropyrimidines to prevent some of the vascular endothelial growth factor receptor 2 (VEGFR2) and high epidermal growth factor receptor (EGFR) is used However, many synthetic protocols that have been reported as long-term reactions or quick reactions suffer from defects and flaws. Requires a multi-step reaction, requires without water conditions, low efficiency, the use of metal constructions containing materials and special tools or starting substances are examples of these flaws. Therefore achieve new techniques and efficient for the preparation of furo (2, 3, d) derivatives of pyrimidine is still highly desirable [7] Pyrimidine represents a very i nteresting group of compounds, because these compounds are used extensively in phytosanitary, pharmaceutical, and analytical . On the other hand, industrial aspects of this class of compounds is considered. For example, these compounds are used as anti-bacterial and anti-fungal. [8]. This class of compounds also have biological activities [9ââ¬â13]. The role of metal ions in biological processes of life has long been known and is highly regarded. Studying the properties of transition metal complexes with this class of biologically active ligands is very interesting. In this paper, the synthesis and characterization of a number of the ligands and uranyl complexes have been studied. In this work, we report the synthesis and structural studies of the ligand and complex isolated from the reactions of: Bis {N- (2, 4- dinitro- phenyl) N- (3- phenyl- allylidene)- hydrazine} Uranyl (VI) nitrate. Experimental Solvents were purified by standard methods. All reagents were supplied by Merck and were used without further purification. Melting point was measured in an Electro thermal 9200. The FT-IR spectra were recorded in the range 400ââ¬â4000 cm-1 by KBr disk using a Bruker Tensor 27 M 420 FT-IR spectrophotometer. The UVââ¬âVis spectra in CH3CN were recorded with a WPA bio Wave S2 100 spectrophotometer. Thermo gravimetric analyses were done on a Perkin Elmer TGA/DTA lab system l (Technology by SII) in nitrogen atmosphere with a heating rate of 20à ºC/min from 35- 700 à ºC. à ¹ H and à ¹Ã ³ C-NMR spectra were measured on a BRUKER DRX-500 AVANCE spectrometer at 500 MHz. Synthesis of the [UO2(NDPAH)2]2+: For synthesis of the [UO2(NDPAH)2]2+ to a magnetically stirred of ligand (0.88g, 2.8mmol) in acetonitrile(10ml) was added to uranyl (VI) nitrate (0.71g, 1.4 mmol) And the reaction is performed at room temperature. To ensure complex formation and precipitation of the complex. The solid complex obtained was filtered. And to remove material that did not participate in the reaction complex was washed with diethyl ether. Yield, 75%. Anal.

NDPAH is soluble in acetonitrile, acetone, chloroform, DMF, DMSO and diethyl ether insoluble in water, hexane, methanol and ethanol little soluble in dichloro methane. Results and discussion Preparation of Ligand and complex Compounds are quite stable and could be stored without any appreciable changes for long time. Compounds with multiple methods using FT-IR, UV-Visible and à ¹ H and à ¹Ã ³ C-NMR spectra were identified. These compounds were evaluated for thermal analysis. In this paper, a new method for the synthesis of the Bis {N- (2, 4- dinitro- phenyl) N- (3- phenyl- allylidene)- hydrazine} Uranyl (VI) nitrate is presented . Following the single-step reaction between the UO2(NO3)2.6H2O and the NDPAH desired compound is obtained.This method has some advantages for the manufacture of complex. These include: there is no side products and does not require special conditions such as high pressure or high temperature, and that this reaction is a very fast reaction. The [UO2(NDPAH)2]2+ has 290à °C melting points respectively. It is soluble in chloroform, acetone, dichloro methane, DMSO and DMF and insoluble in water, hexane and diethyl ether and slightly soluble in methanol, acetonitrile, and ethanol . The spectral data of the complexes have good relationship with the literature data. The IR spectra of the Schiff base show characteristic bands due to à ½(NH), à ½(C=N) and à ½(N-N), in the region 3111cm-1, (1613, 1133) cm-1 respectively. The strong band in the region 1613, 1133cm-1 in the IR spectra of the Schiff base are assigned to à ½( C=N), à ½( N-N) respectively. In the case of U(VI) complex we observed the following changes. The bands appeared around 1133, 1614, 420 and 935cm-1 due to à ½ N-N, à ½ C=N, à ½ U-N and à ½ O=U=O. Thermo gravimetric analyses The thermal properties of these compounds were investigated by thermo grams (TG, DTG and DTA). Figure 11 shows TGA and DTA curves for [UO2(NDPAH)2]2+. In the temperature range 200-305Ãâ¹Ã
¡C, 57.9% weight losing was observed which was related to the loss of most parts of compound. In the temperature range from 360-500Ãâ¹Ã
¡C, 20.6% weight reduction was found, which was related to the loss of a part of compound. Conclusion It is clear from the above discussion that [UO2(NDPAH)2]2+complex and NDPAH ligand offer a new outlook for chemotherapy. The results of antitumor activity show that the metal complexes exhibit antitumor properties and it is important to note that they show enhanced inhibitory activity compared to the parent ligand. The mechanism by which these complexes act as antitumor agents is apoptosis. It has also been proposed that concentration plays a vital role in increasing the degree of inhabitation.

Cartesian Dualism and the Union of Mind and Body Essay -- Dualism Essay
Cartesian Dualism and the Union of Mind and Body ABSTRACT: Cartesian dualism and the union of mind and body are often understood as conceptions that contradict each other. Diachronic interpretations maintain that Descartes was first a dualist (in the Meditations) and later on developed his stance on the union of mind and body (Passions). Some authors find here a problem without solution. Nevertheless, in the last two decades, some interpretations have been developed intending to give a positive solution to the difficult relation between Cartesian dualism and the union of mind and body. The problem that I find in most of them is that they try to show no incoherence between Descartes' dualism and his conception of the union and interaction by "weakening" or making more "flexible" the dualist doctrine. I develop a synchronic interpretation, based on textual evidence, in order to show that dualism and union appeared simultaneously in Descartes' works. Under this perspective, my claim is that Cartesian radical dualism and the union of m ind and body can be coherently understood only because they belong to different domains of knowledge. Thought and matter are clear and distinct primitive notions that come from reason, whose role is laying the foundations for Cartesian metaphysics and physics, while the primitive notion of union is acquired by the senses and lacks clarity and distinction even while it serves the objective of founding Descartes' moral philosophy. Rene Descartes is well known for his dualist conception. At the same time, Descartes recognized the intimate relation between the human mind and body. Several authors have understood this as a contradiction within Cartesian philosophy. Truly, when Descartes argues in fa... ... (10) A.
