Coca Cola Essay

Organizations need to change and adopt dynamic survival strategies to stay alive in uncertain political, social and economic environment (Hiatt and Creasy, 2003). All environmental factors present in the nature experience change on continuous basis. Human nature resists change, so managing that resistance requires well planned change management strategies. A structured approach to transfer organization, its people and processes from current state to a desired future state is called change management. This process gives employees the ability to accept changes in the existing environment of the business. Change can be of different type for example, change in technology, operations or strategies etc. company needs to implement individual strategies to cope with each type of change. Coca Cola Corporation is among one of the oldest corporations of the world. It has gone through many internal and external changes since it has been in existence. The company has used techniques of change management in order to survive from the consequences of those events. Coca Cola is a type of company that requires making changes in its products and business strategies according to the consumer expectations and external environment. Here in this study we would quote different examples from coca cola corporation’s history and will examine that what were the triggering events for opting the change and what strategies the company developed and implemented in order to successfully going through the transitioning process. Coca Cola is a type of company that requires making changes in its products and business strategies according to the consumer expectations and external environment. Here in this study we would quote different examples from coca cola corporation’s history and will examine that what were the triggering events for opting the change and what strategies the company developed and implemented in order to successfully going through the transitioning process. It is a well known fact that Coca Cola Corporation is an entrepreneurial venture started by one person who bought the formula from another firm and laid foundations of that beverages manufacturing firm. Current structure of the coca cola company is simple with minimal labor and management division. New system that can be adopted by the company may be the â€Å"machine bureaucracy† which has been defined as an organization with clearly defined hierarchy, well defined area of operations, standard operating procedures, proper rules and regulations, well division of labor, formal relationships among the member of organization, centralized decision making, technical competence and standardization of work. The company has faced a lot of external changes, for example in world war II, the company was able to manage its existing position at that time and also entered in many new markets and discovered new niches. The company established 64 plants across the world to supply drinks to the troops (Coca Cola Company, 2006-2011). The company also provided free drinks to soldiers which were the part of its strategy to become a patriotic symbol for the people of the country. Also it boosted the sales, so the company achieved two objectives by carefully planning to respond to that external environmental change. The plants developed by the company in war era helped its expansion after the war. The recent change management at coca cola is directed towards the intrinsic values and motivations of the employees and can be referred to as ‘employee engagement’. The change management process, together with internal branding programs is expected to bring about ideal behaviors in employees, which would align the operations of coca cola worldwide, and bring about efficiency throughout coca cola across all its business segments. Coca Cola Company can use two change management tools to make sure that all people who are required to be the part of change management process. These tools are Force Field analysis and AKADAR model. Force field analysis is a technique developed by Kurt Lewin to scrutinize the forces that are causing an opposition to change process (Bass, 2009). By doing Force Field Analysis, Coca Cola Company will be able to induct people who are in need of appropriate training. Another useful tool is AKADAR model which stands for Awareness, Desire, Knowledge, Ability and Reinforcement. Through AKDAR model, firm creates awareness about the need of change, generate desire in the people to help in transitioning process, give knowledge to the people that how they can help the change process, develop an ability in the people to go through the change and provide them with continuous reinforcement to withstand the change (CMLR, 2011). Coca cola hopes to bring about a thoroughly integrated system of communications, and focus on creating brand relationships with their employees. This would enhance the operations of Coca cola, as an integrated approach would mean all employees believe in engaging fully in the values, and this would become an inherent part of the employees at a personal level. For this purpose, employee engagement surveys are conducted twice every year for all the coca cola associates, which serve to highlight the areas where action is required, and further actions and implementations can henceforth be executed. Employee engagement is very significant to all segments of operations at coca-cola and has translated into performance in areas where employee engagement is higher. For coca-cola, an engaged workforce means: A more committed workforce Employee performance aligned with organizational objectives Employees have a clear idea of what is expected of them and what are the deliverables Customer experience focuses an inherent part of employees’ values, who strives to provide a better experience to the customers. Customer focus was identified as a central tenant of the multi-year engagement strategy to be implemented in 2011(Gee, 2011) Change in inevitable. Therefore, the focus should not be on avoiding change, rather bringing about a smooth transition towards the new change by communication about the change, and ensuring all parties of the change that it is for the best of all those involved. To successfully implement organizational change of any nature, a specific regards to organizational structure, design, culture, management and leadership is required to see whether the change would make a best fit with the organizational goals and objectives. To conclude, it may be said that communication can be a key element to successful change management. Communicate the changes to the employees, tell them why the change was inevitable and how they will benefit from the change. The management should itself adopt a positive attitude towards the change so that employees can follow their lead and welcome the change. Coca-cola as a company has a heritage of embracing change rather than resist it and it should translate into their future endeavors towards change management to ensure that the organization is best poised to market and environmental conditions.

Critical Thinking Assignment Essay

Secular Humanism regarding the question of origin, seems to lean toward the determination â€Å"that matter has always existed and given enough time and chance, the end result is what you see around you today.† (Weider, Gutierrez 64). There is a lack of evidence that God exists and man is viewed rather as a machine, having no control over their existence and once man’s life has come to an end, this machine ends (65). Humanists answer questions of identity by believing that, â€Å"mankind is a product of evolutionary forces† (66). Mankind is viewed as a more refined animal, however mankind is not of higher quality over the animal kingdom. The answers to the question of meaning or purpose is, at best, answered on the basis of his or her importance (68). It is up to him or her to give any true benefit to their life, by making an impact in their life (69). Through this, they are able to make a clear and confident impact in another human beings life. However, since â€Å"man is a machine and ultimately not in control of what happens, life cannot have any real value or significance.† (69). Morality and ethics asks what is morally and ethically right versus wrong and how a human being should live, then God must exist to deliver what is right and wrong (71). That being so, secular humanism does not believe in a God, and nor does He exist. Secular Humanists believe that there is no â€Å"absolute truth†, and relies heavily on the fact that â€Å"truth is dependent upon the individual or society and is subject to change† (71). Secular Humanism is not worried about the question of destiny. Once a human being has passed on, all that matters is what they did do on this earth and making a difference in another person’s life (73). The Biblical/Christian worldview, in comparison to secular humanism on the question of origin, is through theism. (65). Through God, and under one God, everything exists. While the secular humanist has no belief in God and man has no control much like a machine, theism believes â€Å"God is the first cause, the answer to why there is something rather than nothing† (65). The question of identity through secular humanism believes  mankind and the animal kingdom are of equal value, the Biblical/Christian worldview believes that mankind is above the animals, and we are responsible to take care of them (69). While secular humanists place man and his purpose through impacting others in their lives, the Biblical/Christian worldview believes our purpose is having a personal relationship with God and His Son, Jesus Christ (70). While secular humanists have no mutual agreement on the question of morality, and reject â€Å"the absolute truth†, and depends on our society, the Biblical/Christian worldview bases morality or ethics through â€Å"Special Revelation† (72). The need for redemption must take place as we were all born in sin, and we can only be saved through Jesus Christ (72). Mankind is not concerned with destiny, through a secular humanist belief. Whereas, the Biblical/Christian worldviews on destiny is â€Å"dependent upon a person’s choices and their personal relationship with God† (75). Works Cited Dr.Weider, Lew and Dr. Ben Gutierrez.

Economic and Political Changes During the Medieval Ages Essay

Before becoming what it is today Europe went through a lot of changes. After the fall of Rome, Europe was in chaos. This is until Charlemagne helped to restore it, after his death though, Europe was back into chaos. Chaos ended in the High Middle Ages when Europe prospered politically and economically. In the Early Middle Ages, also known as the â€Å"Dark ages† which was after the fall of Rome which was caused because of lack of a centralized government, lack of trade, and lack of formal learning, there was a period of great disorder. Because of Europe’s many natural resources such as their seas which were great for fighting and farming, many Germanic tribes, Viking, and other people tried to attack it. When Charlemagne became Emperor the chaos stopped but after his death it continued again. The High Middle Ages were times of economic and political prosperity for Europe. Europe started using a feudal system, which is a system of government based on control of land. In feudal society everybody had a place. For example, vassals pledged their loyalty to their lords and they helped each other out. Another example is serfs farmed and did other labor work for the lords and kings in exchange for land and food. The feudal system provided Europe with a centralized government. Economically Europe also changed, During the Agricultural Revolution they made new technologies such as the wind mill and iron plow which greatly helped with farming. They also started using the three-field system. Because of their change there was more food and the population grew. Trade routes, trade fairs and towns were also created. Another big change was the Commercial Revolution. Money reappeared and was used to buy and sell goods. Europeans developed new ways of doing business. They created partnerships and an insurance system. This greatly helped business in Europe. In order for Europe to get out of its â€Å"Dark Ages† it had to go through change. By changing politically and economically, it prospered. Even now other civilizations are influenced by this. For example we have an insurance system and use windmills. In order for Europe to prosper it had to go through change.

Note taking starts by listening and seeing, the art of listening requires that one be active in judging, evaluating and relating the issues being presented. Listening intently enables one to gather the main points that give meaning to the information being provided. Recording of this information is the next step in taking notes. These notes are study aids and therefore they can be graphs, drawings, sketches that illustrate points presented in the lecture (Dilaura 28). A look into the lecture notes after the class is over allows one to fill in the details that are vital in understanding the concepts presented by the lecturer. Formulating questions that aid in the study is the next step of note taking. The questions, drawings, graphs will provide the student with an easier task when going through the notes (Dilaura 33). This also allows one to have knowledge of the areas that may not be clear therefore allowing one to approach their lecturers for assistance. In not taking the key ideas should be separated from the supporting explanations such as drawings, graphs, equations. This is by providing a space between key ideas for these annotations.

Euthanasia and Whether it is Morally Justified and Hence Ethically Essay

Euthanasia and Whether it is Morally Justified and Hence Ethically Acceptable - Essay Example There is need for the act of assisted suicide to be morally justifiable to make it ethical. However, the major question is to whom the act is meant to justify morality to. Every case that requires euthanasia should be considered differently with its own tenets. The use of euthanasia is morally justifiable and is therefore ethically acceptable since the use requires the opinion of medical practitioners. If their expert opinion is considered after the condition of the individual is thoroughly analyzed to make sure that all actions to alleviate their pain has been taken and no other options are available, then it is crucial for euthanasia to be applied for the good of the individual as well as that of the people closest to him/her. Many people may argue that there is a higher power that guides human life and that only that power and that power alone is responsible for giving and ending human life. I differ with this position vehemently and I strongly believe in the power of the human be ing to derive his/her own destiny. The advances in technology have given people the power to claim expertise in a certain profession. This is no different for the medical practice. This means that they opinion of these experts should be regarded in light of the advances in technology. ... The theory further suggests that in order for an end to be arrived at, a principle or maxim which is supreme and devoid of human influence is followed. This is the sole scale on which the moral worth of any action is weighed. The theory believes that all human beings were created supreme and as such have it in them an inherent capability to decide what is either good or bad. The father of this theory, Immanuel Kant, strongly believed that a categorical imperative is what is responsible for the actions that human beings choose to follow. The fact that the maxims contained in this theory are universal and as thus are right. The simplicity of this theory is that if for example a maxim stated that killing people who you dislike holds true, then the human race would not exist as ultimately, we will be forced to end the lives of all who we dislike and consequently, those who do not like us will kills us. On that example alone, the Kantian theory tends to suggest that it is impossible for a maxim to be untrue or wrong as it is not ultimately decided by the human being himself but rather on a power that is beyond the human being himself. The theory however only holds true where the human being applying the maxim believes in it and follows it to the latter. The Kantian theory is flawed in some aspects. First, when a person conceives the maxim to hold true but it is no longer a means to an end, then the result may not be what is desired by the theory. The above consequence of the Kantian theory is interpreted as a perfect duty as the maxim has been upheld. In the case of the use of euthanasia, then the end of human life may not follow the maxim since its following will not be the best option for the afflicted

The qualitative research has used wide array of literature and interview with 12 CI consultants, working in different countries to provide guidelines and approach for effective CI. CI is primarily the methodology of gathering of information about the changing business paradigms across the countries with business potential. It provides the business with strong database of knowledge that can be judiciously exploited to gain and maintain competitive advantage. CI is a complex process and must be understood within the broader context of varying socio-cultural, political and legal imperatives of the nations.

Research has analyzed CI practices for developed and developing nations where the scope of expansion exists for US firms which are as follows: 2. CI in developed countries Applications of CI practices are different for myriad reasons which are distinct in their perspectives vis-a-vis culture, technology, political and legal environment etc. 2.1 Europe European Union has huge market potential but cultural diversity across nations necessitate cross cultural understanding. Business must use different strategies to glean information about businesses in different European nations. Telephonic and email is acceptable and cost effective means of communication. Face to face interview should only be followed for competitors. Language barrier is important factor and native language, wherever possible, should be used to gain trust. CI practitioners must flexible in their approach and be prepared for differences in opinions. They must also corroborate data from wide sources. Last but not the least important is that 2-3 weeks before and after main holidays must be avoided as Europeans tend to focus on their holiday plans or busy finishing their backlog. 2.2 Japan Japan has maintained its technological superiority in digital goods like camera, electronics goods etc. in the international market.

Would you agree that Porter's framework of generic strategies is useful for (a) academics, (b) practitioners Illustrate your answer with examples. In 1980, despite its instant recognition as one of the most important theoretical frameworks of the business science, the generic strategies developed by Porter were criticized by many academics and professionals. There is evidence by General Motors which became the market leader within 10 years through implementation of particularly the differentiation strategy chalked out in the framework. GM also have to work efficiently to cover up all the different price ranges which are already present in the market, which will prevent any new entrants from venturing into the market and also to compete with the small player that existed within these price divisions. However,one of the main criticisms is the obsolescence of the model in the current competitive market conditions, when new sources of competitive advantage are available to companies. The new competitive conditions of the 21st century demands a re-formulation of this model in order to integrate the new business paradigms identified and applied by academics and professionals. A re-interpretation of generic strategies from the perspective of market relationships is necessary. The three generic strategies,cost advantage,differentation and focus are said to be

Properties of Zeolites as Cataystics

Properties of Zeolites as Cataystics 1.0 INTRODUCTION TO ZEOLITES Zeolites are crystalline aluminosilicates, composed of TO4 tetrahedra (T = Si, Al) with O atoms connecting neighbouring tetrahedral, that contain pores and cavities of molecular dimensions (Breck, 1974). Many occur as natural minerals, but it is the synthetic varieties which are among the most widely used sorbents, catalysts and ion-exchange materials in the world (Barrer, 1982). The channels are large enough to allow the passage of guest species. In the hydrated phases, dehydration occurs at temperatures mostly below about 400 °C and is largely reversible. The framework may be interrupted by (OH, F) groups: these occupy a tetrahedron apex that is not shared with adjacent tetrahedra. Zeolites are different from other porous hydrates, as they retain their structural integrity upon loss of water. The Structure Commission of the International Zeolite Association identifies each framework with a three-letter mnemonic code (Baerlocher et al., 2001) e.g. Amicite- GSI; Faujasite- FAU etc. 1.1 IMPORTANCE OF GREEN PROCESSES In the chemical industry, the acceptability of a process is not only governed by cost and yield but in terms of eco-friendliness and pollution abatement. Choosing a more efficient catalytic route has greatly improved the efficiency of chemical processes. Green chemistry has been defined as the design of chemical products and processes in order to reduce or eliminate the generation of hazardous substances (Armor, 1999). The principles of green chemistry listed by Armor (1999) employs future approaches to new chemical processes. It includes: efficient use of raw materials, energy efficiency, use of biodegradable products and other subtle features. 2.0 HISTORICAL DEVELOPMENT OF ZEOLITES 2.1 NATURAL ZEOLITES Research in the field of zeolite science and technology made its first steps with natural zeolites and was mostly focused on natural zeolites until the beginning of the 1950s. The history of zeolites began in 1756 when Swedish mineralogist A.F. Cronstedt discovered the first zeolite mineral, stilbite when studying its apparent properties discovered its strange behaviour upon heating although there is no certain proof of its identity. The term ‘zeolite was coined from two Greek words, ‘zeo (to boil) and ‘lithos (stone). On the contrary, the first zeolite, chabazite, described by Bosch DAntic in 1792 has clear evidence in literature. Several other zeolites were discovered in the following years and around 1850, only about 20 zeolite types were reported in mineralogy books, including analcime, brewsterite, chabazite, edingtonite, epistilbite, faujasite, gismondine, gmelinite, harmotome, heulandite, laumontite, levyne, mesolite, natrolite, phillipsite, scolecite, stilbi te, and thomsonite. Starting from the middle of the 19th century until about 1975, there was a moderate increment in the number of zeolites discovered (about one new type every 6-7 years) and a clear acceleration in the last twenty five-thirty years. About 40 natural zeolites are known (Tschernich, 1992). Most zeolites known to occur in nature are of lower Si/Al ratios, since organic structure-directing agents necessary for formation of siliceous zeolites are absent. Sometimes natural zeolites are found as large single crystals, though are very difficult to make in the laboratory. The catalytic activity of natural zeolites is limited by their impurities and low surface areas. However, interests in natural zeolites shifted towards zeolite synthesis and synthetic materials, as they offered a series of advantages such as wider versatility, more open frameworks( for adsorption and catalysis),and quality in constitution and chemistry. As a result, research on natural zeolites, was mainly devoted to ion exchange process which was discovered around 1850 (Thompson, 1850; Way, 1850). Few years later, Eichhorn observed that chabazite and natrolite behaved as reversible ion exchangers. In the early decades of the 20th century, ion exchange selectivity of a variety of zeolites for peculiar cations, e.g., ammonium was performed (Barrer, 1950) and starting from the end of the 1950s, found uses in various sectors of environmental relevance, e.g., treatment of wastewaters and soil rebuilding and remediation. The most recent frontier in the application of natural zeolites is in the field of life sciences. One of the drawbacks of natural zeolite research for application purposes is due to the limited availability of zeolite as it is a precious mineral, compared to the synthetic counterparts which could be mass produced at a lower cost (Colella, 2005). 2.1.1 Formation The pathway of natural zeolite formation is similar to the laboratory synthesis of zeolite. Zeolite nucleation, crystallisation and crystal growth take place as a result of slow to fast cooling of warm to hot magmas(of volcanic origin), which are basic, oversaturated in silicate and aluminate species and contain alkaline and/or alkali-earth cations. hot fluid + volcanic ash oversaturated basic magma zeolite crystals {solution + gel) The magma is obtained via hydrolysis of the original glassy material and is responsible for the tetrahedral coordination of aluminium and together with silicon. The main factors responsible for the structural formation are temperature, chemistry of the ash and the chemical composition of the resulting solution. Gel is formed along the process but is however not directly connected to nucleation and growth, as there is evidence that zeolite nuclei form from the oversaturated solution at the glass shards / solution interface (Aiello et al., 1980). Temperature and time are two factors which differentiate natural zeolitisation from laboratory synthesis. 2.1.2 Physico-chemical properties i.Cation exchange: The ion exchange properties of natural zeolites depend on their chemistry which ismainly in terms of selectivity. Selectivity depends on the framework topology, ion size and shape, charge density on the anionic framework, ion valence and electrolyte concentration in the aqueous phase (Barrer et al., 1978). ii.Reactions with alkalis: Oncein alkaline environments, zeolites become unstable as they tend to transform, similarlyto glassy systems, into more stable phases, usually into other framework silicates (Goto and Sand, 1988). The interaction of zeolite-rich materials with Ca(OH)2 give rise to calcium silicates and aluminates, which upon hydration are able to harden in both aerial and aqueous environments. This behaviour makes them to be known as pozzolanic materials Thermal properties: Heating of zeolite powder induces physical and chemical changes, which have been shown to include water loss (which causes expansion on heating), decomposition and gas evolution, phase transition, structure breakdown, re-crystallisation, melting etc (Colella, 1998). This property enables zeolite tuff stones to display good sound-proofing and heat insulation and serve as good building materials. Depending on zeolite nature, chemical composition and rock constitution, the tuff expands as a result of quick heating at temperatures of 1250 °C or above, inadvertently followed by a rapid quenching to room temperature. 2.2 SYNTHETIC ZEOLITES Early work could be traced back to the claimed synthesis of levynite by St Claire Deville in 1862 as there were no reliable methods for fully identifying and characterising the products. The origin of zeolite synthesis however, evolved from the work of Richard Barrer and Robert Milton which commenced in the late 1940s. The first synthetic zeolite unknown as a natural mineral later found to have the KFI structure (Baerlocher et al., 2001 ) was discovered by Barrer when investigating the conversion of known mineral phases under the action of strong salt solutions at fairly high temperatures (ca. 170-270  °C). Robert Milton was the first person to use freshly precipitated aluminosilicate gels to carry out reactions under milder conditions. This led to the discovery of zeolites A and X (Milton et al., 1989). Initially, the synthesis of zeolites required the use of only inorganic reactants but was however expanded in 1961 to include quaternary ammonium cations leading to the discovery o f silica-rich phases (high-silica zeolites). Subsequently, more synthetic zeolites have been discovered (Baerlocher et al., 2001), as well as zeolite-like or zeolite-related materials (Szostak, 1989) known as zeotypes- represented by microporous alumino- and gallo phosphates (AlPO4s and GaPO4s) and titanosilicates. Studies on understanding zeolite synthesis have continued to be carried out upto the present day (Table 1). This has been due to discoveries of new materials, advances in synthetic procedures, innovations in theoretical modelling methods and, especially, by the development of new techniques for the investigation of reaction mechanisms and the characterisation of products. Table 1: Evolution of materials development in the zeolite field ‘‘Low Si/Al zeolites (1-1.5) A, X ‘‘Intermediate Si/Al zeolites (f2-5) A) Natural zeolites: erionite, chabazite, clinoptilolite, Mordenite Synthetic zeolites: Y, L, large-pore mordenite, omega ‘‘High Si/Al zeolites (ËÅ"10-100) By thermochemical framework modification: highly silicious variants of Y, mordenite, erionite By direct synthesis: ZSM-5, Silicate Silica molecular sieves silicalite Source: Flanigen (1980) 2.2.1 Mechanism of Hydrothermal Synthesis Experimental observations of a typical hydrothermal zeolite synthesis Due to its chemical reactivity and low cost, amorphous and oxide-like Si and Al which make up the microporous framework are mixed with a cation source usually, in a basic water-based medium. The resulting aqueous mixture is then heated in a sealed autoclave at above 100ËšC allowing the reactants to remain amorphous for sometime (induction period) after which crystalline zeolites are detected (Figure 2). Gradually, an approximately equal mass of zeolite crystals which is recovered by filtration, washing and drying replaces all the amorphous materials (Cundy and Cox, 2005).The bond type created in the crystalline zeolite product (e.g. zeolite A or ZSM-5) which contains Si-O-Al linkages is similar to that present in its precursor oxides, therefore the enthalpy change is not great. This process reduces nucleation rates, thereby forming larger crystals. Reactivity of the gel, temperature and pH affect the rate of zeolite formation as an increase in pH and temperature leads to increase in the rate of formation of zeolite crystals. In their mother liquors, the zeolitic phases are metastable, thereby transforming the initial zeolite into an undesired thermodynamically more stable phase (Ullmann, 2002). 2.2.3 Synthesis from Clay minerals Kaolin and metakaolin (calcining kaolin at 500-700 °C) are two important clays used for the production of the zeolites NaA, NaX, and NaY (Breck, 1974; Barrer, 1978) because binder-free extrudates and granules which offer advantages in adsorption technology are produced. 2Al2Si2O5(OH)4 2Al2Si2O7+4H2O Kaolin Metakaolin Depending on the zeolite, the clay is shaped and, SiO2and seed crystals are added and while in the preformed shape, the zeolite crystallises. Alternatively, zeolite is formed when the binder component of metakaolin undergoes hydrothermal treatment with sodium hydroxide solution (Goytisolo et al., 1973; Chi and Hoffman, 1977). Using ultrasonic radiation, reaction rate is enhanced and there is energy saving and lower production cost due to lower temperatures. This process is less often used as it could cause odor of the product due to impurities present in clay e.g. iron 2.2.2 Industrial Zeolite Synthesis Zeolite synthesis is an extremely broad area of research and due to differences in the preparation of each zeolite type, two representative zeolite types, TPA-ZSM-5 and zeolite Na-A, are chosen for a more detailed presentation of the synthesis {Table 2} (Jansen, 2001). Table 2: Synthesis mixtures, physical chemical properties of the representative zeolites Molar oxide ratio Na-A TPA-ZSM-5 SiO2 1 1 Al2O3 0.5 Na2O 1 0.16 H2O 17 49 TPA2O 0.3 T (ËšC) > 150 Physical Chemical properties Pore arrangements 3D, cages connected via windows 2D, intersecting channels Bronsted activity low High Affinity hydrophilic Hydrophobic Pore volume (cm3/g) 0.37 0.18 Source: Jansen (2001) The composition of zeolite product can be expressed by the cation type and its overall Si/Al ratio. In the preparation of zeolite, nucleation is the rate determining step which is influenced by a range of factors dependent on the temperature of the reaction mixture. Low Temperature Reaction Mixture: Here, the reaction mixture is prepared at low temperature, At high pH, condensation occurs when the nucleophilic deprotonated silanol group on monomeric neutral species is attacked (Figure 5). The acidity of the silanol group depends on the number and type of substituents on the silicon-atom (Jansen, 2001). Temperature raise of the reaction mixture from High Temperature Reaction Mixture: At this temperature, zeolites are formed from amorphous material which involves, reorganisation of the low temperature synthesis mixture, nucleation and precipitation (crystallisation). During the induction period, gel and species in solution rearrange from a continuous changing phase of monomers and clusters which disappears through hydrolysis and condensation, in which nucleation occurs (Jansen, 2001). The process particles become stable and nuclei forms, followed by crystallisation which could occur in metastable solid, highly dispersed or dense gel forms. Product quality, reaction time and yield influence efficient production of zeolites by optimising their composition. 2.2.2 Secondary Synthesis Methods Catalytic or adsorbent properties that cannot be achieved by direct synthesis utilise post-synthesis (secondary) treatments to increase catalytic activity, shape selectivity or porosity and thermal/hydrothermal stability. Dealumination and ion exchange are used to carry out these modifications. Dealumination The zeolite structure is selectively dealuminated by acid solutions, washing out aluminium out of the crystal, as was observed for zeolite A. However, for higher silica containing materials (clinoptilolite), a fully decationated structure is produced after continuous acid treatment. The metal ion is replaced with H3O+ followed by (Al+3 + H3O+) removal, generating a hydroxyl nest. Aluminium is removed from the framework but not the crystal by hydrothermal dealumination. The heterogeneity in the concentration of the framework and non-framework of aluminium depends on the type of modification used. Hydrothermal treatment causes the amorphous aluminium to collect on the crystal surface which through fluorosilicate treatment can reduce aluminium centred acid sites. Often, a secondary pore system is generated and hydroxyl nests can be annealed. In order to enhance the catalytic properties as well as stability, silicon, aluminium and other metal ions are introduced into the framework (Szostak, 2001). Other methods of producing thermally and hydrothermally stable cracking catalysts include: use of EDTA, SiCl4 vapor, and (NH4)2SiF6. Acid mediated dealumination process via aluminium extraction and generation of hydroxyl nest (Szostak, 2001) Ion Exchange This is an important technique in pore-size engineering for the production of zeolitic adsorbents (Breck, 1974). Ion exchange used in the production of Brà ¸nsted acid sites has major importance in the synthesis of solid acid catalysts (Ullmann, 2002). Ion exchange can be achieved also, for certain intermediate-silica and high-silica zeolites (e.g., mordenite) by treatment with mineral acids although involves the risk of dealuminating the zeolite framework (McDaniel and Maher, 1976). An indirect route via an ion exchange with ammonium salt solutions must be followed, producing the â€Å"ammonium form† calcined at ca. 400 °C to liberate ammonia and give the hydrogen form (Ullmann, 2002). When cations to be exchanged are positioned inaccessible cages, a sieve effect is produced. pH is an important factor in ion exchanging of highly charged transition metal ions in order to prevent metal hydroxide precipitation especially at low pH. 2.3 CHARACTERISATION OF ZEOLITES In order to determine the relationships between the physical and physicochemical as well as sorptive and catalytic properties of zeolites, it is important to know the structural, chemical and catalytic characteristics of zeolites. Several standard techniques are employed in zeolite characterisation. The most common of which is X-ray diffraction used in determining the structure and purity of zeolites. Others include: x-ray fluorescence spectroscopy (XRF) or atomic absorption spectrometry, used to analyze elemental composition, sorption analysis to study the pore system, IR-spectroscopy, typically using adsorbed probe molecules to characterize the acid sites, scanning electron microscopy (SEM), for determining the size and morphology of zeolite crystallites, high-resolution transmission electron microscopy (HRTEM), nuclear magnetic resonance (NMR) spectroscopy, temperature programme desorption (TPD) and many others (Schà ¼th, 2005). 3.0 GENERAL APPLICATIONS OF ZEOLITES Zeolites are used primarily in 3 major applications: ion-exchange, adsorbents, and catalysts. Natural zeolites play an important role in bulk mineral applications. Adsorbent applications: Common adsorbent applications focus on removal of small polar molecules and bulk separations, by more aluminous zeolites and based on molecular sieving processes respectively (Table 3). Table 3: Zeolite commercial applications as adsorbents Purification Bulk separations Drying: natural gas (including LNG), cracking gas (ethylene plants), refrigerant Normal/iso-paraffin separation, Xylene separation CO2 removal: natural gas, flue gas (CO2 + N2) cryogenic air separation plants Olefin separation, Separation of organic solvents Pollution abatement: removal of Hg, NOx, SO Separation of amino acids, n-nitrosoamines Sweetening of natural gas and liquefied petroleum gas Separation of CO2, SO2, NH3 Source: Flanigen (1980). Catalyst applications: Zeolites have the greatest use in catalytic cracking. They also play a role in hydroisomerisation, hydrocracking and aromatics processing. The strong acidity of zeolites plays a role in hydrocarbon processing. Asides this, they are finding increasing use in synthesis of fine chemicals and organic intermediates in isomerisation reactions, nucleophilic substitution and addition etc. Table 4: Zeolite applications in Catalysis Inorganic reactions: H2S oxidation, NO reduction of NH3, CO oxidation, reduction Hydrocarbon conversion: Alkylation, Cracking Organic reactions: Aromatization (C4 hydrocarbons), Aromatics (disproportionation, hydroalkylation, hydrogenation, hydroxylation, nitration, etc.) Dehydration Epoxidation Beckman rearrangement (cyclohexanone to caprolactam) Methanol to gasoline Chlorofluorocarbon decomposition Shape-selective reforming Source: Flanigen (1980); Galarneau et al (2001). Ion-exchange applications: Zeolite properties are directly exploited in several applications such as in the detergent industry, where zeolites are used for water softening or ‘building, animal food supplementation and in the treatment of wastewater (Townsend and Coker, 2001). Zeolite A has selectivity for Ca2+, thereby providing a unique advantage. Also, natural zeolites can be used to remove of Cs+ and Sr 2+radioisotopes through ion-exchange (Payra and Dutta, 2003). Table 5: Applications and advantages of Ion-exchange Applications Advantage Metals removal and recovery High selectivities for various metals Removal of Cs+ and Sr2+ Stable to ionizing radiation Detergent builder zeolite A, zeolite X (ZB-100, ZB-300) Remove Ca2+ and Mg2+ by selective exchange, no environmental problem Ion exchange fertilizers Exchange with plant nutrients such as NH4+ and K+ with slow release in soil Source: Flanigen (1980) Other Applications: Zeolites also play important roles in health-related applications (such as antibacterial agents, vaccine adjuvants, drug delivery, bone formation, biosensors and enzyme mimetics), oil refining, and petrochemical processes. Zeolite powders are used for odor removal and as plastic additives. Zeolitic membranes offer the possibility of organic transformations and separations coupled into one unit (Payra and Dutta, 2003). 3.1 ZEOLITES AND THE ENVIRONMENT Nearly all applications of zeolites are driven by environmental concerns, from cleaning toxic (nuclear) wastes, to treatment of wastewater, thereby reducing pollution. Zeolites have now been used to replace harmful phosphate builders in powder detergents due to water pollution risks. Zeolite catalysts help to save energy as they make chemical processes more efficient, minimising un-necessary waste and by-products. When used as solid catalysts and redox catalysts/sorbents, they reduce the need for corrosive liquid acids and remove atmospheric pollutants, (such as engine exhaust gases and ozone-depleting CFCs) respectively (Bell, 2001). In wastewater, zeolites (clinoptilolite, mordenite) are used to remove ammonia and ammonium ions (Townsend and Coker, 2001), as well as heavy metal cations and transition metals. 3.2 ZEOLITE CATALYSTS IN GREEN CHEMISTRY Zeolite catalysts have contributed to the design and synthesis of novel materials and development of new methodologies in organic synthesis, displacing the conventional and waste generating reagents thereby maximising atom utilization and reducing waste generated (E-factor). Zeolites play an important role in acid-catalyzed reactions such as acylation, alkylation, isomerisation and condensation, cyclisation and electrophilic aromatic substitution. Acylation of aromatic substrates: used in fine chemicals manufacture although has proven unsuccessful in less reactive aromatic compounds due to adsorption imbalance, unless performed in vapor phase using H-ZSM-5 (Singh and Pandey, 1997). 4.0 CONCLUSION Due to the role zeolites play mainly as catalysts in the environment as well as in chemical industry, the efficiency of the zeolite catalysts has been greatly improved. The yield and selectivity of the zeolite process is quantitative and in addition, reduces energy requirements, capital costs and complexity of equipments. Over the years, the synthesis process of zeolites have encompassed the principles of green chemistry as described in the report which has included waste prevention, energy efficiency, fewer environmental impacts, safer solvents, renewable materials, process intensification, catalysis and reduction in capital cost. Though present techniques seem to apply some of the principles of green chemistry, further research is still being employed to improve the overall process. 3.0 REFERENCES Aiello, R., Colella, C., Casey, D.

Scandle in the church :: essays research papers

Headlines were captured in February by the tragic reports that as many as seventy priests in the Archdiocese of Boston, Massachusetts, allegedly have abused young people whom they were consecrated to serve. In the wake this news, allegations of sexual abuse by Catholic priests have sprung up nationwide. It is a huge scandal, one that many people who dislike the Catholic Church because of its moral teachings are using to claim that the Church is hypocritical and that they were right all along. Many people have come up to priests like myself to talk about it. I imagine many others have wanted to but have refrained out of respect or from not wanting to bring up bad news. We need to tackle the issue head-on. We cannot pretend it doesn't exist, and I would like to discuss what our response as faithful Catholics should be to this terrible situation. The Judas syndrome The first thing we need to do is to understand this scandal from the perspective of our faith in the Lord. Before he chose his first disciples, Jesus went up the mountain to pray all night (Luke 6:12). He had many followers at the time. He talked to his Father in prayer about whom he should choose to be his twelve apostles-the twelve whom he would form intimately, the twelve whom he would send out to preach the good news in his name. He gave them power to cast out demons. He gave them power to cure the sick. They watched him work countless miracles. They themselves worked countless others in his name. Yet one of them tuned out to be a traitor. One who had followed the Lord-who had seen him walk on water and raise people from the dead and forgive sinners, one whose feet the Lord had washed-betrayed him. The gospels tells us that Judas allowed Satan to enter into him and then sold the Lord for thirty pieces of silver, handing him over by faking a gesture of love. "Judas," Jesus said to him in the garden of Gethsemane, "would you betray the Son of Man with a kiss?" (Luke 24:48). Jesus didn't choose Judas to betray him. But Judas was always free, and he used his freedom to allow Satan to enter into him, and by his betrayal Jesus was crucified and executed. But God foresaw this evil and used to accomplish the ultimate good: the redemption of the world.

Animal Farm, by George Orwell :: Animal Farm Essays

Animal Farm Essay by George Orwell   Ã‚  Ã‚  Ã‚  Ã‚  In the book Animal Farm, by George Orwell, the idea of how power can corrupt is depicted in the novel. The theme of the novel is â€Å"Power corrupts and absolute power corrupts absolutely†. When one receives to much power, such as the character Napoleon, it forms a dictatorship like government in which all decisions are made by one man. When a revolution happens, or a sudden change occurs people begin to grow unhappy while working for their government with no say in any political decisions.   Ã‚  Ã‚  Ã‚  Ã‚  When the animals of Animal Farm took over there main beliefs were based on their made up commandments called Animalism. The beliefs derived from this law were basically that â€Å"man is our enemy†, â€Å"all animals are comrades†, â€Å"do not become like man†, and â€Å"no animal should be more powerful then another†. These views were from Old Major, who had given a speech to stir the animals into rebellion. Old Major’s dream was for the earth to be ran by animals. When Old Major died, Snowball, Napoleon, and Squealer replaced him. At first things started off pretty well; the harvest was very good the first year and the reading and writing system had helped some, but had limited success on others. Napoleon soon shared his view on education and took the puppies into his home and started teaching them. In time the leaders of animal farm started to have mixed feelings. Snowball said the animals only had to work three days a week, but Napoleon said it would only result in the animals starving to death. Napoleon then had the dogs kill off Snowball. Napoleon had eliminated Sunday morning meetings. The committee of pigs were now the leaders and there were no more debates. Napoleon soon started brainwashing the lower class of animals to believe him. The traditions of Old Major were soon forgotten, it was now Napoleons plans. Under new leader Napoleon the work week had been extended so that each animal had to work 60 hour weeks. Napoleon also hired Mr. Whymper as a go between for trade. Napoleons hiring of Mr. Whymper had gone against Animal Farms motto. The pigs now lived in the house and changed some of Animal Farms laws such as â€Å"no animal shall sleep in a bed† was now changed to â€Å"no animal shall sleep in a bed with sheets†. The laws were changed to fit Napoleons needs. Napoleon had changed around their seven commandments One was â€Å"no animal shall kill another†,this was changed to â€Å"no animal shall kill another without

The Veldt by Ray Bradbury :: Veldt

The Veldt by Ray Bradbury   Ã‚  Ã‚  Ã‚   The story of The Veldt, is a delving into the issue of how modern technology can destroy the nuclear family.   The editor of the Encounters book, John A. Rothermich comments that "This story is almost devoid of characterization.", I agree with this statement and think it is key to the plot of the story.   Ã‚  Ã‚  Ã‚   The story begins with the mother of the family, who has quite a generic name.   We are given no information of the characters background and how they came to the point in time they are now.   The lines "Happylife Home" and the familiar room settings like the parent's bedroom and the nursery give you a sense that this is a typical suburban home of the time. The mother seems alarmed or confused about something, "the nursery is...different now than it was", this at first might lead you to believe the mother has true individual characteristics.   However, when you read on, you see the stereotyped reactions to every situation that comes about, the parents then say "nothing's too good for our children".   Ã‚  Ã‚  Ã‚   Later in the story the parents discuss the problems of the incredible house and nursery, "The house is wife, mother, and nursemaid, Can I compete with it?", and the father has a generic answer "But I thought that's why we bought this house".   The parents in the story look upon their children's needs as services instead of ways of expressing any love or care.   Ã‚  Ã‚  Ã‚  Ã‚   In the story we never learn anything about the children except for their obsession with the nursery, "I don't want to do anything but look and listen and smell; what else is there to do?".   When the parents tell the children the idea of shutting down the computerized house "for a vacation", the children react shocked and stay with their one, single characteristic given, they act shocked "Who will fry my eggs for me, or darn my socks?". You see then the children's primary relationship is to the house and not the parents, the children exclaim "I wish you were dead!".   And sure enough, by the end of the story the children act on their on

Mental Models About a Person’s World Essay

INTRODUCTION: Meeting a person for the first time, can either be a positive or negative experience and the way someone interacts with this person can also show both positive and negative behaviours. So the question is, how can mental models about a person’s world, both aid them and also limit their perceptions when meeting a person for the first time. Through exploring how and why these perceptions can be assisted and limited, we can start to question the reasoning behind our mental models. MENTAL MODELS Throughout the years, academic literature has defined a mental model in many ways, however the best way to understand what a mental model is, is the deeply imbedded ways of thinking or even certain images, that trigger assumptions and generalisations, ultimately affecting the way a person responds too or behaves in the world, be it towards a person or a life situation (Senge 2006). A good example of a mental model is, the generalization that only rich people live in the eastern suburbs of Sydney. This generalisation may be true in some cases, but in other cases, other people may live there because they have lived their all their lives, and so, we can see this particular generalisation or â€Å"mental model† has not be thought through. Not questioning mental models, can often lead to false generalisations, this situation can also arise when meeting a person for the first time. When meeting a person for the first time, our mental models can help us both understand and ultimately get along with the person or they can limit our perceptions, meaning we make assumptions or generalisations that eventually alter our perceptions about this person or how we act towards them. Very often, we see that we are not consciously aware of our mental models and the affects that they can have on our behaviour (Chermack 2003), this in turn, restricts our perceptions. Mental models are often vague, incomplete and imprecisely expressed (Karp 2005) however, once believed, mental models are extremely difficult to change (Chermack 2003). This is highly due to the  fact that people are unaware of their own mental models, and the only way for a person to change their mental model, is for them to acknowledge that they have one to start with. Mental models can be useful as they can help us to process information and make decisions quickly (Unknown 1997) and they can also be imperative foundations for building knowledge about the world we live in (Karp 2005). For instance, when an individual has a mental model that all take away food is bad for their health and wellbeing, when given the option of either having take away food or a healthy meal at home, the individuals mental model will therefore lead them to quickly decide to eat a healthy meal at home. However, very strong mental models can hinder active thinking and the acceptance of new ideas (Unknown 1997), and often arise problems when they are tacit, meaning that they are below the level of awareness (Senge 1992). Using the example of the Detroit auto maker, not recognising that they had the mental model that all that customers cared about was styling, believing that â€Å"all people care about is styling†, evidently shows us that their mental model had become tacit. This mental model continued to be unexamined, and because this mental model remained unexamined, the model remained unchanged, and thus as the world changed the gap grew between the mental model of this Detroit automaker and the world (Senge 1992). Clearly, mental models can perform as filters that screen incoming information that come to us, limiting our ways of thinking and also our perceptions (Unknown 1997). An individual’s mental model represents their view on the world, it also provides them with the context in which they view and interpret new material and also new people in which they meet for the first time (Kim 1993). It not only helps us to make sense of what is going on around us, but it can also restrict our understanding of a certain situation. For example, when someone has been labeled as not a nice person, with never questioning the validity of it, people create a mental model that, that person is not nice, and so when they do or say something nice it goes unnoticed, and therefore, the behaviour does not fit with the mental model people have towards this  certain individual. These untested assumptions or mental models can eventually cause conflict and misunderstandings between people. Developing skills in reflection and inquiry can aid us in realising our mental models and also with dealing with others. When we use skills of reflection we slow down our ways of thinking and acknowledge how our mental models are formed and how they affect our behaviour. Where as skills of inquiry, is concerned with how we operate in face-to-face situations with others, especially when we are dealing with complex and conflictual issues (Senge 2006). Together with the tools and methods used to develop these skills these constitute the core of the discipline of mental models, which consists of; the distinctions between espoused theories and theories-in-use, recognising â€Å"leaps of abstraction†, exposing the â€Å"left-hand column† and balancing inquiry and advocacy (Senge 2006). When an individual says that they value or desire something, that is known as espoused theory, however, what they actually say or do, is known as theories-in-use (Bocham 2010). Acknowledging the gaps between what we say and what we do, can be seen as an effective reflective skill in becoming more aware of our mental models. Someone may profess their view (espoused theory) that people generally are trustworthy, but their actions (theories-in-use) show differently, as they never lend out money and keep their possessions to themselves (Senge 2006). As evident in the example above, there is a gap between the individual’s espoused theory and their theory-in-use. By recognising the gap between espoused theory and the theory-in-use, learning can occur, as we as individuals question whether or not we really value our espoused theory (Senge 2006). When we meet a person for the first time, we can quickly jump into generalisations as we never think to question them. For example, when we meet a person and they say that they are a doctor, we automatically assume that they are smart, as it is a generalization that all doctors are smart we never seem to question this mental model. These are known as â€Å"leaps of abstraction†. â€Å"Leaps of abstraction† occur when we move from direct observations to generalisations without questioning them, this ultimately  impedes learning because it becomes axiomatic, as what was once an assumption is now treated as a fact (Senge 2006). Therefore, this becomes another limitation, in which mental models can have on our perceptions when we meet people for the first time. However, these â€Å"leaps of abstraction† can easily be identified when people ask what their generalisation is based-on and whether or not the generalisation is inaccurate or misleading (Senge 2006) Senge (2006) identifies the â€Å"left-hand column† as a powerful technique whereby individuals begin to see how their mental models operate in differing situations. This exercise can show individuals that they indeed have mental models and show them how those models play an active part in sometimes negative interactions with people, not only do these people become aware of their mental models, but they begin to acknowledge why dealing with these assumptions is imperative (Senge 2006). In order for good communication between individuals to arise, people need to recognise that in order for the communication process to be effective, mental models must be managed properly, this is done by balancing advocacy and inquiry (Peggy & Bronn 2003). Advocacy is the process of communicating an individual’s ways of thinking and reasoning in a manner that makes it clear for others (Peggy & Bronn 2003). When there is advocacy without inquiry, it only leads to more advocacy, and therefore leads to two individuals stating their ways of reasoning and thinking, they both are keen to here the others views, but do not inquire into what they are saying because they believe that what they are saying is ultimately the best way of thinking. A way to tackle this, is through the process of inquiry. Inquiry engages two individuals into the communication process in a joint learning process (Peggy & Bronn 2003). Here the objective is to understand the reasoning and thinking of the other individual, this can be done by asking them questions in order for them to determine the origin for their conclusions and statements (Peggy & Bronn 2003). Individuals can do this by asking questions such as; â€Å"What is it that leads you to that position?† and â€Å"can you illustrate your point for me?† (Senge 2006). Thus, it is evident  that grasping the skill of balancing advocacy and inquiry, is highly advantageous in interacting with other individuals, especially those you meet for the first time. CONCLUSION: Therefore, it is imperative and highly advantageous for us to question our mental models in everyday situations, such as meeting people for the first time, as it will deter us from automatically making assumptions and making generalisations. Through acknowledging ‘leaps of abstraction†, using the â€Å"left-hand column† technique and also personally mastering the skill of balancing advocacy and inquiry, we can learn to question these mental models, and thus questioning whether or not they really do hold their value in our world. Thus, when we meet a person for the first time, before we make assumptions and generalisations, we may need to recognise our imbedded mental models and learn to question them, therefore aiding the process of communication to be a positive experience.

And the more strongly associated with a concept facts are, the more rapidly they are verified.3) Verifying facts that are not directly stored with a concept but that must be inferred takes a relatively long time. bed cover activation Models (Collins & Loftus) Words represented in lexicon as a network of relationships Organization is a web of interconnected nodes in which connections can represent categorical relations class of association typicality Retrieval of information gap activation Limited amount of activation to spread Verification times depend on closeness of two concepts in a network Context effect in spreading activation models symbolise either Murder is a curse or Libel is a plague Then get verification time for Robbery is a crime Subjects faster when they see Murder than Libel.
