Organizational Innovation and Change - Critical Thinking Mod 1 Essay

Organizational Innovation and Change - Critical Thinking Mod 1 - Essay Example Likewise, there was a need to assess internal resources (including financial support, as well as coordinated time and effort of all members) to make the transferring to another home, possible. In addition, not only was there a need to transfer to a new local community, but to search for the nearby educational institutions, as well as employment opportunities to support and sustain a successful change. Personal Experience as a Story of Change Just like the stories of change presented by authors Palmer, Dunford, & Akin (2009), the story of moving made it a story of change due to the presence of both internal and external factors that contribute to the need to change. Likewise, after establishing the need, the strategies were aptly designed to ensure that the actual change (moving) is implemented within a defined time frame, and with little resistance, as possible. Of course, all members of the family need to be duly informed, and as much as possible, any resistance to the required chan ge had to be effectively addressed and managed through strategies that included open communication, proposing opportunities for growth, and emphasizing that the future would be more productive and rewarding with the proposed change. Similarities with Change Lessons From Hewlett- Packard change story, the following elements were similarly present in one’s personal story of change: (1) that â€Å"different interests need to be recognized and addressed† (Palmer, Dunford, & Akin, 2009, p. 9); (2) that the interests apparently provoked different reactions to the change process: from resistance, anxiety, anticipation, relief, among others; (3) that skills of negotiation and persuasion are needed in the process; (4) that â€Å"communicating change often entails providing a vision of the future that is compelling† (Palmer, Dunford, & Akin, 2009, p. 9); and (5) that pressures or factors that led to change come from both internal and external sources. Moving to another re sidence share these similarities in terms of having identified that internal and external factors impinge on the current status and necessitate moving. For instance, the change in employment or assignment to another state was the primary reason for moving and that retaining the current residence would have been unproductive and irrational. From the IBM change story, one noted that there were similarities shared in terms of having recognized: (1) that â€Å"change requires a marshaling of appropriate resources† (Palmer, Dunford, & Akin, 2009, p. 9). Likewise, from the change story of Kodak, one shared the same experience in terms of manifesting that â€Å"change involves risk and uncertainty† and that its consequences could not always be predicted (Palmer, Dunford, & Akin, 2009, p. 9). There were similarities in one’s personal change story after identifying that current financial resources need to be evaluated to assess the feasibility for moving and to determine if the potential income related to the new employment of one’s father could aptly support the cost of living in the new state. Of course, there were risks and uncertainties that include being immersed in a new environment and being potentially exposed to unfamiliar people with diverse cultural backgrounds. The elements that were utterly not applicable in one’

Chemistry Tasks - Scholarship Essay Example 6. A conjugate acid base pair are the compounds formed by the removal or addition of a proton from the original compound. In the question, only H3O+ and OH- are not a conjugate acid base pair as there is a difference of 2 protons. 9. The aqueous solution of a salt would be acidic if the salt consists of the conjugate base of a strong acid and conjugate acid of a weak base. Therefore the aqueous solution of NH4F would result in a acidic solution. 12. The aqueous solution of a salt would be basic if the salt consists of the conjugate base of a weak acid and conjugate acid of a strong base. Therefore the aqueous solution of NaCH3CO2 would result in a basic solution as NaOH is a strong base and CH3COOH is a weak acid. 13. Arrhenius base is the substance that when added to water increases the concentration of OH- ions present in the solution. NH3 when added to water does not increase the concentration of OH- ions therefore it is not an Arrhenius base. 14. Arrhenius acid is the substance that when added to water increases the concentration of H+ ions present in the solution. Addition of FeCl3 to water would not increase the concentration of H+ ions in the solution, so it is not a Arrhenius acid. From this it is clear that the reaction moves in the forward direction, which means that HNO2 gets converted to NO2- and CH3COO- gets converted to CH3COOH. Therefore it is clear that CH3COOH is a weaker acid compared to HNO2. So for this reaction CH3COOH is the weakest acid. 17. We know that pH = -log[H+] therefore if the pH increases by 1. The H+ concentration would decrease exponentially by a factor of 10. 18. Molecular weight of Ba(OH)2 is 171.34 g/mole. Therefore the moles of Ba(OH)2 added would be (5/171.34) = 0.029 moles. Each mole of Ba(OH)2 would dissociate to give 2 moles of OH- ions. So, we have

Leadership Case Study: Virgin Group

Leadership Case Study: Virgin Group Founded in 1970 as Virgin Records, the company has expanded to a humongous organization comprising of more than 200 companies in 2007. Its business portfolio ranges from air travel, fitness centers, and mobile telephony. Since its inception, the culture and image of Virgin Group has been directly attributed to the personality and efforts of its owner and founder, the high-ranking executive and entrepreneur Sir Richard Branson. It makes no sense to delink Virgin Group from Sir Branson. In fact, the name Branson is almost becoming synonymous with Virgin Group. This essay aims to provide several aspects of Virgin group. These include the critical analysis of its organizational model, the leadership of Sir Richard Branson and eventually organizations communication. Discussion Virgin Group is made up of more than 200 companies, which employ nearly 50,000 people all over the world. The business has witnessed continual growth since it was started. The revenues reached a record mark of 10 billion sterling pounds in the year 2006. This reveals the magnitude and level of business in which Virgin Group is operating. The nature of leadership in existence in Virgin Group draws many features from the personality of Sir Richard Branson. The business philosophy postulated by Sir Richard Branson believes that the ultimate results of customer satisfaction and shareholders gain is the responsibility of every individual. He believes that if the staffs are kept happy then the customers are going to be happy meaning that the shareholders will be happy too. Consequently, the management of Virgin Group does not fall in to any particular model. It has a unique management structure whose characteristics do not fit those of the existing models. The amalgamation of concepts make s it distinctive. A critical review reveals that the success witnessed by Virgin Group can be attributed to the uniqueness of its management styles. Management Theorists like F Taylor first created the concept of scientific management. This scientific concept postulates that there are six main features of management, namely; experiment, observation, selection, standardization, and training. Scientific philosophy of management expects that rewards and employee compensation should be pecked on performance and co-operation. Although some facets of this theory are outdated, some of its features are still applicable in the business structure of modern times. As a good illustration, Virgin group may be having what appears as a relaxed working environment but some features of scientific management are in application. Such aspects of scientific management used in Virgin Group include training, selection, and payment pecked on results. Some employees are compensated because of their outstanding entrepreneurial ambition and innovative thinking. Outstanding performance in Virgin Group is not only measure by the amount of financial input an employee has brought but also creativity and ability to think outside the box. Another model of management is bureaucracy, which sees the organization of business as one unit. The pioneers of this school of thought believed that family practices could not be delinked from the organization. Therefore, there a need to merge family goals with those of the entire organization. Organizational goals of Virgin Group cannot be dissociated with those of Sir Richard Branson. This is enough reason to conclude that the management style in the organization has some elements of bureaucracy in leadership. Max Weber first formulated this kind of management approach. The impact of entire society is given considerable attention by the management. In this model, the organization is considered as an integral part of an amorphous society. Despite having some draw backs, this model has found its way in to the Virgin Groups management style. In a bid to meet the needs of the society it is serving, virgin management give priority to the impact, its strategies will have on the society. This is the reason as to why Virgin Atlantic, an airline company under Virgin Group, has been on the frontline on the crusade for environmentally friendly jet fuel. Furthermore, there is an element of administrative theory in the management of Virgin Group. Propounded by Henry Fayol, administrative theory view management as a chronological process comprising of planning, organization, training, and coordination of functions. This model represents the transitional theory between the traditional and modern models. It is characterized by rigid and mechanistic tenets. Virgin Group has a little bit of these management principles. It has deviated from it by allowing liberalized management at departmental level. However, at the departmental levels, there is need to advance the principles of management. The thoughts of employees should remain to be customized to suit these principles. The management of Virgin group with a heavy weight is contingency approach. The decision-making and plans executions are done with close reference to the problem at hand. This has seen the group attain notable milestones in streamlining its management, which eventually translates in to revenues. In this management model, the dynamics of business environments is appreciated. It recognizes the fact that different environments require different management approaches. Concisely, it is true to argue that Virgin Groups success story of many years is a factor of many things including it optimal management model. The group has been able to amalgamate the presets of every model to suit its present needs. What is emerging vividly from this global organization is the fact that the efficacy of management is determined by its ability to move away from conventional and rigid requirements. Moving with the trends in the market has been proven beneficial in optimization of profits. From the descriptions given above, it is evident that Virgin Group leadership is a transformational. In transformational leadership the management looks beyond the compensation to the employees. The model, which is in use at Virgin Group, explores the inner factors, which enhance performance of employees through motivation. On contrary to transactional model, which look at compensation alone, transformational leadership looks at way of achieving high-level loyalty and commitment from the followers. The brand in the name of Virgin was founded in 1968. Since then it has grown beyond borders and become a worldwide product. Its venture into many different industries is a true reflection of success. Sir Richard Branson is the present chairperson of the group. He is well known for his stylish but competitive leadership skills. Many analysts and scholars attribute the success of Virgin Group to the creative leadership skills of Branson. In the process of expansion, he took over several risky ventures in a more to diversify and improve his business. In most of his business plans, he focused on minute segment of a specific market and provided quality products or services. This approach allows for creation of small monopolistic markets with high profit margins. One major contributor to Bransons success story is his ability to lead people in exploring innovative and profitable ventures. Therefore, the leadership style depicted by Branson is a topic to be investigated in the following disc ussions. The kind of leadership philosophy advocated by Branson has been infiltrate into the entire company. Sir Richard Bransons leadership style falls in the category of transformational. He has an outstanding ability of bringing out the best out of humanity. Interpersonal and relational skills possessed by Branson are impeccable. He has close touch with the day to day activities of various companies within his group. The most common feature that has made him achieve great milestones in business development is the ability to motivate and rally fellow partners in pursuit of a business opening. If the recent acquisitions are taken as an illustration, he managed to convince fellow stakeholders in adoption of new strategy. In his ventures, he looks for people who are outgoing and willing to start new businesses. His capacity building nature has made him an admirable leader of modern business. His focus spans beyond the orthodox perspective of employees where the management expects the workers to perform to deserve compensation. The interest of Branson surrounds asking the question as to whether a partner or employee is optimizing his or her capacity. He is interested also with people who are willing to take risks and the best in their tasks. For a long time, he has succeeded in bringing out the best out of his staff, a core character of transformational leader. There is no doubt about the fact that Bransons success since 1970s is directly attribute to his attitude towards management of a team. In his approach, the barrier existing between the employees and management is broken. In fact, many people working with him approaches business issues with a philosophy of achieving through innovative thinking and not adhering to the preset rules. Because of the ideologies propagated by Branson, all participants in the organization share similar values. He formulated his own style of leadership, priding himself on integrating the employees in to his style and seeking their thoughts on ways of improving value to customers. Employees are expected to internalize these values and respond in accordance to them. Integration of corporate values in leadership strategies means that there is little interference by external forces. Nevertheless, Sir Bransons approach does not mean that the employees are entirely dependent on the chairmans thoughts. They are equally accountable of their actions like fellow employees under transactional leadership. In order to motivate his employees, Branson and his management team, especially human resources management department have systems of enhancing commitment of employees through bonuses, stock options and profit sharing, and internal promotion wherever possible. Apart from Sir Bransons input in the success of virgin Group, there is a contribution of organizational culture in the company. Organizational culture existing in Virgin Group in fairly complex. The Group serves more than 100 companies operating separately in the industries which are not entirely related. The common feature within ever company in the group is the glamorous Virgin Brand. The brand remains unchanged in all companies operating in different businesses. This is a similarity, which puts a heavy responsibility on each department or division to positively represent the brand. The image reveals an overall image of quality and innovation inherent in the group. Through the creation of an exclusive brand, the company has been able to consolidate and maintain desirable loyalty levels among the customers. The diverse business portfolio evident in Virgin Group businesses is helpful in building and maintaining loyalty in various industries. This is the main reason as to why the company has witnessed high levels of success. The managers in the company employ the concept of creativity to encourage employees to enhance their contribution to the group in whatever level of hierarchy. They discourage the scenario where employees sit back to execute instructions. Employees have the capacity of producing cutting-edge products, which the whole company will be able to deliver to the market. They can also formulate ways of improving efficiency in the company. This is an outstanding feature of Virgin Group. Every individual has a say when it comes to products development. The management style in application at Virgin Group encourages members of staff to be competitive. This will eventually build a desire in the hearts of employees to see the company succeed so that they can be recognized as contrib utors to new and innovative business model. There is no clear cut between management and leadership within Virgin Group. Transformational leadership emanates from executives and top managers in the company. There are harmonized goals set by Sir Richard Branson and fellow company executives. Various companies within the group will work towards achieving those goals. These ambitious goals range from utilization of new technology, expansion in international markets, joint venture with other existing companies and loyalty among customers. Goals formulated at this level of management are communicated to every employee in the company. This is a beneficial strategy, which gives every employee a task to accomplish in fostering the groups mission. The senior management implores the employees to output their skills in such a way that they are going to complement the company. The notion behind this effort is to advance the philosophy that the entire benefits of the group will eventually lead to individual gains for every person involved. The contribution in the group will ultimately result in rewards for managers, employees, shareholders, executives, and customers alike. One desirable feature of Virgin Group is its organizational structure. Through its structure the company has succeeded in overcoming the challenges related to expansion. An expansive organization like Virgin Group must explore ways of handling the massive information within the company. Through its flat organizational chart, Virgin Group Limited has been able to handle it expansive business portfolio with much ease. The reduction of horizontal chain of command means that interdepartmental communication is enhanced. As the level of hierarchy moves down, the lower levels of management tend to concentrate more keenly on the management of the company. Although leadership is always encouraged among the managers, it requires some levels of strict management to make sure that the task has been accomplished. Different divisions within the company have different management function. At Virgin Group, managers have several goals of wide scope. Because of the fact that different divisions of the company are specialized in their operations, well-trained and qualified mangers are required to manage it effectively. In most cases, managers employed by the company have a firm background in their sector of specialization. They must also prove that they are capable by showing a successful record of accomplishment. It is the sole responsibility of managers within Virgin Group to ensure that day-to-day operations needed to keep the division running are executed effectively. Organization is a vital ingredient in the success of Virgin companies. Since the group in an amorphous company comprising of several companies, organization is very critical in putting together the processes. To start with, the company has many goals to be achieved like expanding the global presence and building of customer loyalty. The top executive are responsible for determining these goals and making them available to the entire company. The same executive must ensre that these goals are achievable for them to be received well by employees. However, caution should be exercised to ensure that the employees are not underutilized. Challenging goals are important for the employees to feel that they are engaged in meaningful tasks. Organization of these goals within the division will ensure that specific targets are made. Every division have separate and specialized goals aimed at increasing market share and improvement of product and services. As the hierarchy advances to the junior staffs, goals become more precise and short lived. The targets set at implementation levels are easily achievable because they are very specific. These specific goals are formulated by division managers with close reference to those of the entire group. This system of information transfer enables the company to remain on track on the journey to meeting the targets set by executives. Virgin is a living evidence for the fact that this kind of organization is a major prerequisite for business success. Breaking down of general goals in to actionable points is a desirable feature revealed in Virgins organization. A healthy and workable organizational structure witnessed in Virgin Groups businesses is attained with many varying strategies. Transformational leadership is one of these strategies that have seen the company attain great heights of success. This strategy enables people of diverse backgrounds and ability to share a common goal. Through working together, a team can combine its members efforts and work towards achieving common goal. Transformational leadership gives everyone an equal chance to output his or her ability without reservations. A critical review of Virgin Group business reveals that its versatile and innovative workforce is due to the transformational leadership in place. This is in contrast with transactional leadership in which employees are compensated according to performance. The draw back with this kind of leadership is that it breeds greedy employees whose goal will be to amass rewards as much as possible. Conclusion In conclusion, there are many things to be learned from leadership and management of Virgin Group Limited. The company has cut itself a niche in various industries. It has also proven that all things are possible with dedication and commitment. Through the able leadership of its Chairman, Sir Richard Branson, the management team has come up with a unique formula of managing large scale businesses like Virgin Group. To a large extend, the success of Virgin Group is directly attributable to the input of Sir Branson. He has succeeded in opening a new chapter of management, which deviates from conventional methods. His liberal and all accommodating approach is desirable. There is a formidable blend between management and leadership. A critical review of these two elements reveals that there is no clears cut between the two: a feature that has worked well for the company. Chemical bonds: An introduction Chemical bonds: An introduction Introduction A chemical bond is an attraction between atoms brought about by a sharing of pair of electrons between to atoms or a complete transfer of electrons. There are three types of chemical bonds: Ionic, Covalent and Polar covalent. In addition chemists often recognize another type of bond called a hydrogen bond. Among all these three chemical bonds the strongest bond is covalent bond and weaker from covalent bond is ionic bond and weakest among all is polar bond. The main condition for a covalent bond to be formed is that both atoms forming covalent bond should have equal electro negativity or nearly equal electro negativity. For example: carbon can form covalent bond with oxygen and carbon but a covalent bond between carbon and nitrogen is never possible because there is high difference between electro negativity of carbon and nitrogen. Explanation Chemical bond A chemical bond is an interaction between atoms or molecules and allows the formation of polyatomic chemical compounds. A chemical bond is the attraction caused by the electromagnetic force between opposing charges, either between electrons and nuclei, or as the result of a dipole attraction. The strength of bonds varies considerably; there are strong bonds such as covalent or ionic bonds and weak bonds such as dipole-dipole interactions, the London dispersion force and hydrogen bonding. Since opposite charges attract via a basic electromagnetic force, the negatively-charged electrons orbiting the nucleus and the positively-charged protons in the nucleus attract each other. Also, an electron positioned between two nuclei will be attracted to both of them. Thus, the most stable configuration of nuclei and electrons is one in which the electrons spend more time between nuclei, than anywhere else in space. These electrons cause the nuclei to be attracted to each other, and this attraction results in the bond. However, this assembly cannot collapse to a size dictated by the volumes of these individual particles. Due to the matter wave nature of electrons and their smaller mass, they occupy a very much larger amount of volume compared with the nuclei, and this volume occupied by the electrons keeps the atomic nuclei relatively far apart, as compared with the size of the nuclei themselves. In general, strong chemical bonding is associated with the sharing or transfer of electrons between the participating atoms. Molecules, crystals, and diatomic gases— indeed most of the physical environment around us— are held together by chemical bonds, which dictate the structure of matter. * Main types of chemical bonds In the simplest view of a so-called covalent bond, one or more electrons (often a pair of electrons) are drawn into the space between the two atomic nuclei. Here the negatively charged electrons are attracted to the positive charges of both nuclei, instead of just their own. This overcomes the repulsion between the two positively charged nuclei of the two atoms, and so this overwhelming attraction holds the two nuclei in a fixed configuration of equilibrium, even though they will still vibrate at equilibrium position. In summary, covalent bonding involves sharing of electrons in which the positively charged nuclei of two or more atoms simultaneously attract the negatively charged electrons that are being shared. In a polar covalent bond, one or more electrons are unequally shared between two nuclei. In a simplified view of an ionic bond, the bonding electron is not shared at all, but transferred. In this type of bond, the outer atomic orbital of one atom has a vacancy which allows addition of one or more electrons. These newly added electrons potentially occupy a lower energy-state (effectively closer to more nuclear charge) than they experience in a different atom. Thus, one nucleus offers a more tightly-bound position to an electron than does another nucleus, with the result that one atom may transfer an electron to the other. This transfer causes one atom to assume a net positive charge, and the other to assume a net negative charge. The bond then results from electrostatic attraction between atoms, and the atoms become positive or negatively charged ions. All bonds can be explained by quantum theory, but, in practice, simplification rules allow chemists to predict the strength, directionality, and polarity of bonds. The octet rule and VSEPR theory are two examples. More sophisticated theories are valence bond theory which includes orbital hybridization and resonance, and the linear combination of atomic orbitals molecular orbital method which includes ligand field theory. Electrostatics is used to describe bond polarities and the effects they have on chemical substances. Valence bond theory In the year 1927, valence bond theory was formulated which argued essentially that a chemical bond forms when two valence electrons, in their respective atomic orbitals, work or function to hold two nuclei together, by virtue of system energy lowering effects. In 1931, building on this theory, chemist Linus Pauling published what some consider one of the most important papers in the history of chemistry: â€Å"On the Nature of the Chemical Bond†. In this paper, building on the works of Lewis, and the valence bond theory (VB) of Heitler and London, and his own earlier work, he presented six rules for the shared electron bond, the first three of which were already generally known: 1. The electron-pair bond forms through the interaction of an unpaired electron on each of two atoms. 2. The spins of the electrons have to be opposed. 3. Once paired, the two electrons cannot take part in additional bonds. His last three rules were new: 4. The electron-exchange terms for the bond involve only one wave function from each atom. 5. The available electrons in the lowest energy level form the strongest bonds. 6. Of two orbitals in an atom, the one that can overlap the most with an orbital from another atom will form the strongest bond, and this bond will tend to lie in the direction of the concentrated orbital. Bonds in chemical formula The 3-dimensionality of atoms and molecules makes it difficult to use a single technique for indicating orbitals and bonds. In molecular formulae the chemical bonds (binding orbitals) between atoms are indicated by various different methods according to the type of discussion. Sometimes, they are completely neglected. For example, in organic chemistry chemists are sometimes concerned only with the functional groups of the molecule. Thus, the molecular formula of ethanol (a compound in alcoholic beverages) may be written in a paper in conformational, 3-dimensional, full 2-dimensional (indicating every bond with no 3-dimensional directions), compressed 2-dimensional (CH3-CH2-OH), separating the functional group from another part of the molecule (C2H5OH), or by its atomic constituents (C2H6O), according to what is discussed. Sometimes, even the non-bonding valence shell electrons (with the 2-dimensional approximate directions) are marked, i.e. for elemental carbon.C. Some chemists may a lso mark the respective orbitals, i.e. the hypothetical ethene−4 anion (/C=C/ −4) indicating the possibility of bond formation. Strong chemical bonds Typical bond lengths in pmand bond energies in kJ/mol.Bond lengths can be converted to by division by 100 (1 Ã… = 100 pm).Data taken from Bond Length(pm) Energy(kJ/mol) H — Hydrogen H-H 74 436 H-O 96 366 H-F 92 568 H-Cl 127 432 C — Carbon C-H 109 413 C-C 154 348 C=C 134 614 C≠¡C 120 839 C-N 147 308 C-O 143 360 C-F 134 488 C-Cl 177 330 N — Nitrogen N-H 101 391 N-N 145 170 N≠¡N 110 945 O — Oxygen O-O 148 145 O=O 121 498 F, Cl, Br, I — Halogens F-F 142 158 Cl-Cl 199 243 Br-H 141 366 Br-Br 228 193 I-H 161 298 I-I 267 151 Strong chemical bonds are the intramolecular forces which hold atoms together in molecules. A strong chemical bond is formed from the transfer or sharing of electrons between atomic centers and relies on the electrostatic attraction between the protons in nuclei and the electrons in the orbitals. Although these bonds typically involve the transfer of integer numbers of electrons (this is the bond order), some systems can have intermediate numbers. An example of this is the organic molecule benzene, where the bond order is 1.5 for each carbon atom. The types of strong bond differ due to the difference in electronegativity of the constituent elements. A large difference in electronegativity leads to more polar (ionic) character in the bond. Covalent bond Covalent bonding is a common type of bonding, in which the electro negativity difference between the bonded atoms is small or nonexistent. Bonds within most organic compounds are described as covalent. See sigma bonds and pi bonds for LCAO-description of such bonding. A polar covalent bond is a covalent bond with a significant ionic character. This means that the electrons are closer to one of the atoms than the other, creating an imbalance of charge. They occur as a bond between two atoms with moderately different electro negativities, and give rise to dipole-dipole interactions. A coordinate covalent bond is one where both bonding electrons are from one of the atoms involved in the bond. These bonds give rise to Lewis acids and bases. The electrons are shared roughly equally between the atoms in contrast to ionic bonding. Such bonding occurs in molecules such as the ammonium ion (NH4+) and is shown by an arrow pointing to the Lewis acid. Molecules which are formed primarily from non-polar covalent bonds are often immiscible in water or other polar solvents, but much more soluble in non-polar solvents such as hexane. Ionic bond Ionic bonding is a type of electrostatic interaction between atoms which have a large electro negativity difference. There is no precise value that distinguishes ionic from covalent bonding but a difference of electro negativity of over 1.7 is likely to be ionic and a difference of less than 1.7 is likely to be covalent Ionic bonding leads to separate positive and negative ions. Ionic charges are commonly between −3e to +3e. Ionic bonding commonly occurs in metal salts such as sodium chloride (table salt). Bonds in chemical formula: he 3-dimensionality of atoms and molecules makes it difficult to use a single technique for indicating orbitals and bonds. In molecular formulae the chemical bonds (binding orbitals) between atoms are indicated by various different methods according to the type of discussion. Sometimes, they are completely neglected. For example, in organic chemistry chemists are sometimes concerned only with the functional groups of the molecule. Strong chemical bonds: Strong chemical bonds are the intramolecular forces which hold atoms together in molecules. A strong chemical bond is formed from the transfer or sharing of electrons between atomic centers and relies on the electrostatic attraction between the protons in nuclei and the electrons in the orbitals. Although these bonds typically involve the transfer of integer numbers of electron some systems can have intermediate numbers. Aromatic bond In organic chemistry, certain configurations of electrons and orbitals infer extra stability to a molecule. This occurs when Ï€ orbitals overlap and combine with others on different atomic centres, forming a long range bond. For a molecule to be aromatic it must obey Hà ¼ckels rule, where the number of Ï€ electrons fit the formula 4n + 2, where n is an integer. The bonds involved in the aromaticity are all planar. In benzene, the prototypical aromatic compound, 18 (n = 4) bonding electrons bind 6 carbon atoms together to form a planar ring structure. The bond order (average number of bonds) between the different carbon atoms may be said to be (18/6)/2=1.5, but in this case the bonds are all identical from the chemical point of view. They may sometimes be written as single bonds alternating with double bonds, but the view of all ring bonds as being equivalently about 1.5 bonds in strength, is much closer to truth. In the case of heterocyclic aromatics and substituted benzenes, the electronegativity differences between different parts of the ring may dominate the chemical behavior of aromatic ring bonds, which otherwise are equivalent. Metallic bond In a metallic bond, bonding electrons are delocalized over a lattice of atoms. By contrast, in ionic compounds, the locations of the binding electrons and their charges are static. Because of delocalization or the free moving of electrons, it leads to the metallic properties such as conductivity, ductility and hardness. Intermolecular bonding There are four basic types of bonds that can be formed between two or more (otherwise non-associated) molecules, ions or atoms. Intermolecular forces cause molecules to be attracted or repulsed by each other. Often, these define some of the physical characteristics (such as the melting point) of a substance. A large difference in electronegativity between two bonded atoms will cause dipole-dipole interactions. The bonding electrons will, on the whole, be closer to the more electronegative atom more frequently than the less electronegative one, giving rise to partial charges on each atomic center, and causing electrostatic forces between molecules. A hydrogen bond is effectively a strong example of a permanent dipole. The large difference in electro negativities between hydrogen and any of fluorine, nitrogen and oxygen, coupled with their lone pairs of electrons cause strong electrostatic forces between molecules. Hydrogen bonds are responsible for the high boiling points of water and ammonia with respect to their heavier analogues. The London dispersion force arises due to instantaneous dipoles in neighbouring atoms. As the negative charge of the electron is not uniform around the whole atom, there is always a charge imbalance. This small charge will induce a corresponding dipole in a nearby molecule; causing an attraction between the two. The electron then moves to another part of the electron cloud and the attraction is broken. A cation-pi interaction occurs between the negative charges of pi bonds above and below an aromatic ring and a cation.

The article was a recently published article, 2012, and William Wheeler has a good background in politics, specifically giving some focus to the politics of water, for which he received an award as noted in the article, http://www.bu.edu/cghd/files/2011/04/Disaster-Conference-Speaker-Bios.pdf What qualifications does the author have for writing the NO article on this subject? (This may also apply to quotes within the article.) Stewart M. Patrick is a senior fellow and director of the International Institutions and Global Governance Program at The Council on Foreign Relations. (p. 89, Easton) The following are a list of his expert experiences according to http://www.cfr.org/experts/international-institutions-global-governance-multilateral-institutions-un-failed-states-sovereignty/stewart-m-patrick/b5863 Multilateral cooperation, International Institutions, and Global Governance United Nations Transnational Threats Foreign Assistance Post-conflict reconstruction Stewart was a graduate of Stanford University. When and where the NO article was first published? Does this affect its credibility? The article, The Coming Global Water Crisis. What Happens When Demands for this Essential Resource Starts Exceeding Supply in many Parts of the World? (Easton), was published on May 9, 2012, in the Atlantic magazine. The author has a good knowledge and background, especially with an interest of weak and failing states. Having said that, and with the article somewhat new, I would say that the publication and the author both are credible. EFFECTIVE ARGUMENT TECHNIQUES See information at the end of this worksheet about creating effective arguments. Students are required to address the issue by exploring both articles and both sides of the argument. SUMMARY OF YES ARGUMENT POINTS SUMMARY OF NO ARGUMENT POINTS William Wheeler, the author of the yes argument, believes that supply or lack thereof, is not a real concern but that it is more about valuing water and how it is used. There is just as much water in the world now as there always has been, water supply has not decreased. The evaporation process has not changed and water is still cycled through the water cycle. Meaning that water is evaporated into the air, it then rains, in lakes, rivers and freezes in the glaciers, plants absorb it and the process starts all over. Water is being used up quicker than it can be replaced. Droughts give reason to fear a water crisis. The phrase Global Water Crisis leaves the impression that there is a major water crisis/shortage. Too much water can be just as devastating as not having enough water. Water feeds crops, powers cities, cools computer servers and is key to the manufacturing of everything from clothes to cars (p. 84) Increase in population will increase demand for water. The better a region is doing economically, the more water they demand all due to the consumption of more meat rather than wheat. Livestock, in which the meat comes from, needs more water than wheat does. Water Resource Group suggest that by 2030 almost half of the world population will be hit with a severe water shortage and by 2050, 1 in 5 developing countries will too. Water shortage is also due to too many tube wells draining the water. Human are living beyond their means, meaning that they are consuming more water than they really have available and at a higher rate than water is being replenished. Leaking infrastructure are also a reason for water shortage. Climate change, increase in global grain prices and droughts, some caused by record high temperatures, are contributing factors to water shortage. Rising sea levels can damage wall protections as well as increase the risk of coastal storms. Poorer regions will be more affected by the water shortages. Global Water shortage should be a concern of everyones not just the region or area affected by it. Climate change will increase the rate that glaciers melt off when regions depend on the glacier water as a resource at the same time that other regions, already distressed by drought, will become more distressed by increase drought. As water shortage becomes more of an issue, regions will use it as an economic source and will build dams to keep it from running off to lower land regions. They will focus on keeping as much water as they can, close to home. This will cause conflict and risk of terrorist attacks. More than 15 countries rely on hydropower to generate at least 80 percent of their electricity (p. 86) and if water shortage is not handled properly, regions could be faced with energy shortage in addition to, food supply being affected and run a higher risk of waterborne diseases. Professor Lalls believe is that water shortage is blown out of proportion and isnt really as bad as it is being made out to be. Professor Lall believes that one way of fixing the crisis is to be more aware of what crops are being grown and where these crops are being grown, reducing waste, recycle water and repurpose flood-control systems, to name a few. He also mentioned involving the government to ensure easy access to rural and urban areas as well as accessing cheap soil moisture sensors are used to improve agricultural water efficiency. Professor Lall states that everyone should be paying more for water as another way to help regulate water usage. Professor Lall states that what the U.S. needs is a policy that incorporates forecasts, trading mechanisms, options, and coordinated use of both surface and ground-water resources. (p.87) Drought in Sahel will threaten 15 million lives. Global Warming will affect global demand for fresh water versus the availability of the supply of fresh water. Population growth also will affect the available supply of water. Regions dealing with major water shortage will eventually run into issues with pollical and social instability. The planets fresh water source is about 2.5% Growing global water demand for fresh water are a result of increase in population, as it will continue to increase in the coming years, reduction in available fresh water due to the melting away of the glaciers as a result of global warming, individuals are consuming more meats over wheat, where it takes more water to feed the livestock than it does to grow wheat, and poor management of the water. Water shortage increases tension amongst regions and they begin to come territorial over their water source, leaving room for issues globally by building dams and things of the sort to keep from losing water to another region. Internationally there are only 263 water basins that are shared. Managing the water source includes stopping the leaks from infrastructures, new irrigation systems and growing crops that use less water and can withstand drought, which would improve agriculture efficiency, pricing water based on its real value and making clear the rights to water sources. CRITICAL THINKING AND REFLECTION ARTICLE-SPECIFIC QUESTIONS *Answer all of the questions listed at the beginning of Exploring the Issue for each set of articles. 1. I believe that the increased demand for future water are 100% real. Both articles bring up many points as to why the demand will increase in the near future. Those include, increase in the population, climate change increases drought in some areas while melting the glaciers in other areas, increasing the risk of hurricanes from rising sea levels and once the glaciers meltdown, there will be no more water source in the future. Water is also underpriced and as mentioned in both articles as well. It was also mentioned that management of water source is a problem. 2. I believe that moderating the distribution of water would help the water shortage but I do not believe that it is the main culprit of global water shortage. I think it is more a combination of multiple culprits. 3. No, I do believe that global warming changes the result of adverse changes in the supply of and demand for water, I believe it has a huge impact on the supply of however. Global warming will soon dry up most if not all of our water resources. 4. I do not believe that just taking any one action will avert the world global water crisis. As I have stated in the above questions, I believe that it will take an all or nothing approach. There are many pieces to the puzzle and by focusing just on one piece, the others may get worse while you think you are working to solve the crisis. 5 I have more faith in focusing on a broader approach of a better integrated water management system for a brighter future global water system than anything else. I believe being broad and giving attention to all of the factors that are attributing to the water crisis is the only way to approach the situation. EFFECTIVE ARGUMENT TECHNIQUES Acknowledge differing viewpoints This technique strengthens your argument in 3 ways: It helps you spot flaws on the opposing side. It can help you spot flaws in your own argument. It establishes your credibility as someone who can address the issue in a reasonable way and at least consider opposing points of view EXAMPLE: The installation of cameras does cost an immense amount of money. They also give no privacy to the students. (This writer is actually in FAVOR of security cameras. In the introduction, however, he raises these two arguments against the cameras to establish credibility.) WARNING! If you acknowledge a differing viewpoint, dont just say the other side has a valid point and leave it at that. Move on to the next step of rebuttal. Rebut differing viewpoints A strong argument points out the flaws in the other sides thinking using reasonable language and examples. INTRODUCTION EXAMPLE: The installation of the cameras does cost an immense amount of money. They also give no privacy to the students. However, they would be convenient for the schools security. CONCLUSION EXAMPLE: Even though the installation of cameras is expensive and offers no privacy to student, it does help the security of the school. Strategies for Writing an Effective Argument.

Carver After you have read the passage carefully, distinguishing between purported facts and opinions, answer the following questions thoroughly. What is the authors conclusion? What premises does the author provide to support this conclusion? What assumptions (unstated premises) are required for the authors argument to be valid? Do the premises seem uncontroversially true? If not, explain. Do the assumptions seem uncontroversially true? If not, explain. Are all terms in the argument adequately defined? If not, explain. Are there other facts, not discussed, that would be helpful to know in evaluating the argument? If so, explain. Does the author appeal to emotion or use words designed to influence our response? (e.g., discounts, hedges, assurances, repetition, etc.) If so, explain. Is your well-crafted version of the argument valid? That is, suppose the premises and assumptions are true, regardless of their actual truth or falsity. Ask yourself, given their truth, does the conclusion have to follow? (If so the argument is valid, if not, it is invalid.) If a clear valid/invalid answer is difficult, explain why. In your opinion, is your well-crafted version of the argument sound? That is, does it both have a valid form and have all true premises and assumptions? (If so, it is sound, if not, it is unsound.) Explain your answer.

Hamlet As An Aristotelian Tragedy Essay -- essays research papers

According to the Aristotelian view of tragedy, a tragic hero must fall through his or her own error. This is typically called the "tragic flaw", and can be applied to any characteristic that causes the downfall the hero. Shakespeare's Hamlet, Prince of Denmark can be seen as an Aristotelian tragedy and Hamlet as it's tragic hero. Hamlet's flaw, which in accordance with Aristotle's principles of tragedy causes his demise, is his inability to act. This defect of Hamlet's character is displayed throughout the play. In the opening scenes of the play, the Ghost of old Hamlet reveals the truth about his death to his son, and tells Hamlet to avenge the murder. Hamlet's first response is one that sounds of speedy action, saying "Haste me to know't that I with winds as swift†¦ May sweep to my revenge." (p. 34 lines 29-31) Unfortunately, Hamlet's inability to act on his father's extortion has him reluctant to kill King Claudius by the end of that very scene, when he says, "This time is out of joint, O cursed spite, that I was ever born to set it right." (p. 41 lines 190-191) As the play goes on, Hamlet still has yet to act on his murderous task. In act II, scene 2, Hamlet decides that, before he can avenge his father's death, he must make sure that the Ghost was telling the truth. This simply gives Hamlet more excuse to procrastinate-he gets to put off killing Claudius until after the "play within a play", Mousetrap, is preformed. Not surprisin...

How does Shakespeare create an effective opening to Hamlet? Essay

The key purpose with the opening of any piece of literature is to entice and enthral the reader and obviously Shakespeare having the fame and staggering success that he has had, must be well aware of this. If questions are left in the readers mind once reading the opening to this script or watching the play, they engage the audience as they want these questions answered and believe that as the play unfolds they will be. The attitudes and values of the characters that are introduced in the first act contribute greatly to the sense of suspense the audience feels. Shakespeare begins the play with the entry of two minor characters ‘two Sentinels’. By doing this the audience only get a second hand taste of what the key themes are going to be later on in the play. There is no omniscient feel to this first act, only an air of mystery. The very first line spoken by Barnardo, ‘Who’s there? ‘ even creates this sense of unknowing, and also implies that the Sentinels are on edge for some reason and perhaps even frightened. This question is then repeated by the second sentinel, Francisco, as Horatio and Marcellus answer. Again the ambiguity of the question, ‘has this thing appear’d again tonight? ‘ creates mystery and a feel of foreboding. A ghost then appears and it is absolutely clear that the sentinels are immensely frightened, ‘tremble and look pale’. The Ghost then disappears without speaking, despite Horatio’s efforts, ‘I charge thee speak’. This allows the audience to wonder what this Ghost has come to tell the Sentinels and as the characters discuss the Ghost, both the audience and characters are as bewildered at this entry of this supernatural being. When the ghost reappears it is hopeful that it will speak, however at the exact point it appears it is about to, Shakespeare again dangles the carrot under the audiences nose as a cock crows disrupting the Ghost and causing it to instantaneously disappear. The anonymity of the Ghost appearing in the first act instigates the audience to speculate over the significance of the Ghost and the anonymity of its appearance. Furthermore the appearance of the Ghost allows the audience to realise the importance of Horatio within the play, he is an educated ‘scholar’ who is clearly respected by the sentinels. However at this point it is unclear to the audience the reason for which he will play a key role in the play. Carrying on from this the setting in which this first scene is set also adds to the sense of unknowing and mystery. The scene is set outside the castle of Elsinore on a gun-platform; this suggests to the audience even at this early stage that war or battles will be present later on in the play as castles are built solely for the purposes of protect in conflict. It is also dark and night, this adds to the fear of the sentinels as they cannot see who it is that approaches them. This is clear with the opening line ‘Who’s there? ‘ spoken by Barnardo. Furthermore perhaps the dark night setting is intentional pathetic fallacy by Shakespeare, as the characters and even the audiences’ unknowing towards the Ghost is mirrored by the way in which the characters cannot see clearly and have to ask of who approaches them. This pathetic fallacy is carried on into the ending of the scene, as the cock crows and it becomes morning the sense of fear leaves the sentinels, this is shown with the semantic fields used in their speech, of ‘love’ and ‘life’. Although much is still unknown when this first scene ends many themes are vaguely introduced to the audience. Death is clearly evident with the spontaneous appearances and disappearances of the Ghost. There is a semantic field of death running throughout the dialogue, Shakespeare uses descriptive words like ‘look pale’, and also ‘dead hour’. This adds to the audiences feeling of unease as well as illustrating the characters. Also the old King Hamlet is said to be similar to the Ghost in appearance, this is a way of Shakespeare indirectly introducing the theme of the death of the King, and also as the death is obviously fresh in the mind of the sentinels and Horatio so it seems to be the case that this will be an avid theme within the play. Barnardo states when the Ghost first appears that it is ‘In the same figure as like the King that is dead’. Another key theme that is introduced is war, this is introduced through the setting itself as I have already mentioned, but also through the discussion of the guards and Horatio proceeding the departure of the Ghost. The Ghost was wearing the ‘armour he (the dead King) had on when he th’ ambitious Norway combated’. Suggesting perhaps there is still conflict going on, but Shakespeare is clever as he never explicitly lets the audience know what is going on in this first scene, grabbing their attention and interesting them further in what is commencing in the play. This first scene finishes with Horatio and the guards going to impart their news of the Ghost onto ‘young Hamlet’. This shows a great respect for Hamlet, it also implies that Hamlet is the King as the audience have previously been told that ‘Old King Hamlet’ has died. This is rather ironic as later the audience come to find out that in fact it is young Hamlet’s uncle that is now become King through an unconventional marriage. So putting this into perspective this could imply that some subjects, such as Horatio slightly resent the marriage of the Queen to Hamlets uncle. I conclude that this is an extremely effective opening written by Shakespeare as it constantly engages the audience, and makes the audience feel a need to know more of what the play is about.
