Why Using Experiential Learning With Adults Is Powerful

Kolb and Frye, two leaders in adult educational theory, say that adults learn best through active participation and reflection. This form of learning is called experiential because it involves hands-on experience and observation as well as discussion and other forms of learning. What Is Experiential Learning? In a sense, experiential learning is simply learning by doing -- but there is more to the process. Not only do learners take action, but they reflect on, learn from, and take new action based on experience. Kolb and Frye describe experiential learning as a four-part cycle: The learner has concrete experience with the content being taught.The learner reflects on the experience by comparing it to prior experiences.Based on experience and reflection, the learner develops new ideas about the content being taught.The learner acts on her new ideas by experimenting in an experiential setting. When the new ideas are put into action, they become the basis for a new cycle of experiential learning. Examples of Experiential Learning Its important to understand that experiential learning is not identical with hands-on learning or apprenticeship. The purpose of experiential learning is not simply to learn a skill through practice, but also to think critically about the practice and to improve upon it. For a child, hands-on learning might involve mixing baking powder and vinegar and watching it bubble and rise. This activity is good hands-on fun, but it doesnt necessarily provide the child with a full understanding of the chemical interaction between the two materials.   For an adult, hands-on learning might involve working with a trained carpenter to learn how to build a chair. In this case, the learner has gained some skills -- but has not taken part in experiential learning. The next step would involve taking time to reflect on the experience and compare chair-building to other building projects. Based on reflection, the learner would then develop new ideas about how best to go about building a chair and return to chair building with new insights and ideas. Pros and Cons of Experiential Learning Experiential learning can be very powerful for adults because they have the life experience and cognitive ability to reflect, develop new ideas, and take positive action. It also provides adults with the real-world experience they need to place their new skills in context and to develop new ideas about how to implement their skills. This is particularly true when real-world skills are taught in a classroom context. For example, a classroom experience with providing CPR is very different from a real-world experience in the back of an ambulance. On the other hand, experiential learning has very specific limits. It is only useful when the  content being taught is content that will be used in a real-world setting. So, for example, it is very difficult to provide experiential learning relative to literature, history, or philosophy. Yes, it is possible to take field trips to relevant locations or museums -- but field trips are quite different from experiential learning.

From studying its own website, HTC’s culture is competitive and diverse. Under the â€Å"Careers† tab, nine different employees’ pictures are featured with a video advertising HTC’s appeal as an employer. Five of the nine employees pictured are women; three are women of color, and all nine employees appear to be under the age of 40. HTC’s culture is hip, diverse, and fastpaced. The video stressed that technology is constantly improving and the â€Å"best idea† rather than the â€Å"biggest title† moves forward. This shows that the culture at HTC values creativity and competition (â€Å"HTC. Com†). HTC makes annual donations to the Social Welfare and Charity Foundation or Educational Foundation. This foundation funds leadership and character training for elementary, junior high and senior high students, cosponsors local community development and urban cultural revitalization efforts, targets the special needs of disadvantaged groups, and provides disadvantaged children opportunities to further their academic careers. Running head: HTC CORPORATION 4 The HTC Foundation established the nation’s first institute dedicated to character-building and English training in the Hualien’s Meilun District. The institute provides character-building and English enhancement curricula free of charge to fourth grade elementary school students from around Hualien County. In addition, the Foundation offers scholarships for children with special financial needs and financial aid to low-income families and sponsors after-school tutoring programs. Each year, Foundation disbursements benefit over 2,000 youth from disadvantaged families both in Taiwan and overseas (â€Å"HTC. Com†). HTC STRATEGY HTC Corporation uses a differentiation strategy to attract customers looking for more choices. HTC expects differentiation product in terms of innovation and execution. They focus on innovation and execution to enhance product proposition and offer consumers a variety of products. When they think of increasing the quality and the variety of the product, they first consider what the customer will value. They are offering a wide range of product lines to outperform their competitors like Apple and Nokia. HTC has produced an amazing number of phones, all of which have an impressive array of applications and features. They do have the cutting edge when it comes to hardware, but if a consumer can’t afford these more expensive versions HTC’s older models (like the Hero) are still well built and functional. In addition, HTC offers a variety of body forms and builds, including some devices with physical keyboards (â€Å"htc. com†). FINANCIAL POSITION To shadow on the financial stability of the HTC CORP I used liquidity ratio and leverage ratio. The liquidity ratios measure the company’s ability to cover its expenses. The two main liquidity ratios I used to analyze the company’s financial health are current ratio and quick ratio (â€Å"investing. businessweek. om†). 1) The Current Ratio is a reflection of financial health. It is the number of times company’s current assets exceeds the current liabilities, which is the indication of the solvency of that business. The formula to compute the current ratio is Using the earlier Balance Sheet data of the HTC C ORP, we can compute the company’s current ratio as: = = 1. 3 times This tells us that the current liabilities are covered by current assets by 1. 3 times. The HTC CORP is able to cover their short term expenses which are meant to be covered with in a period of one year. 2) The Quick Ratio is also called the acid test ratio. This is because it looks at the company’s most liquid assets and compares them to current liabilities. The quick ratio tests whether a business can meet its obligation even if adverse conditions occur. The formula to compute the quick ratio is: Assets considered being quick assets include cash, bonds, stock, and accounts receivable. Using the Balance Sheet data of the HTC CORP, we can compute the quick ratio of the company as: Running head: HTC CORPORATION = = = 1. 1 times 5 This indicates that the ratio is considered satisfactory, as long as the collection of the receivables is not expected to slow. So the HTC CORP seems to have adequate resources to cover its debts. In order to identify the long term coverage of the company, we are focusing on one of the main leverage ratios. Leverage ratio measures the stability of a company and its ability to repay its debts. These ratios are of particular interest to banks. They should be of interest to shareholders as well since it gives the strong indication of the financial health and the viability of the business. 3) The Debt-to Equity Ratio is a measure of how dependent a company is on a debt financing as compares to owners equity it shows us how much of a business is owned and how much is owed. The Debt-to-Equity ratio is computed as follows: Using the Balance Sheet data of the HTC CORP we can compute the debt-to equity ratio: Times Since the Debt-to-equity ratio is greater than 1, i. e. , (1. 8 times), the capital provided by the lenders exceeded the capital provided by the owners. But because of the greater ratio it has high risk defaults too. It varies with the type of business and the risk attitude of management. Year over year HTC has been able to grow over their bottom line from $29 billion to $59 billion primarily through revenue growth ($142. 9 billion to $277. 7 billion). For a while the costs associated with cost of goods sold, and income tax all increased as a percentage of sales, the growth in top lines revenues contributed enough to still see net income. HTC Corporation uses little or no debt in its capital structure and may have less financial risk than the industry aggregate. Accounts Receivable is typical for the industry, with 58. 31 days worth of sales outstanding. Lastly, HTC Corporation is among the least efficient in its industry at managing inventories, with 30. 39 days of its Cost of Goods Sold tied up in Inventories (â€Å"investing. businessweek. com†). Therefore the overall financial tability of the corporation is stable and healthy. They have adequate resources to cover their debts and unforeseen uncertainties. MY CAREER at HTC Yes, HTC could be good place to obtain my first career oriented-position. HTC is the part of the global market that breeds flexibility, new technologies and innovation. It will create a platform for the new opportunities to explore and do creative things. I fit the HTC profile of being young, educated and a global citizen: while growing up in Kashmir and going to college in America, I’ve relied on technology and most recently, my own smartphone, to navigate my day. I would bring creativity and a fresh perspective to HTC’s worktable. Running head: HTC CORPORATION REFERENCES Bloomberg Businessweek. (2012, April 10).

Protein Ligand Interaction-Free-Samples for Students-Myassignment

Question: Discuss about the Protein Ligand Interaction. Answer: Introduction Oxidative phosphorylation is the process that involves the formation of ATP and constitutes the fundamental and most important means of energy production for the cells of animal, plant and bacterial origins (Jonckheere, Smeitink Rodenburg, 2012). Apart from oxidative phosphorylation, photophosphorylation is also involved in the synthesis of ATP and both these processes are dependent on the F1F0-ATPase enzyme complex for catalyzing the ATP synthesis (Nath Villadsen, 2015). The F1F0-ATPase enzyme is also called the ATP synthase enzyme. The source of energy that helps to carry out ATP synthesis is an electrochemical proton gradient. This proton gradient is produced by the electron transfer complexes that are present in the mitochondria, chloroplast or the bacterial membranes (Jonckheere, Smeitink Rodenburg, 2012). This essay describes the protein ligand interactions with respect to the F1F0-ATP synthase enzyme complex (protein) and ATP(ligand). Interaction between F1F0-ATPase and ATP In prokaryotes, the F1F0-ATPase enzyme complex consists of 8 different sub-units while in mammals the number of sub-units are 16-18. The molecular weight of the enzyme typically ranges between 550-650kDa. It is located in the bacterial plasma membrane, while in plants it is located in the thylakoid membrane of the chloroplasts and mitochondrial inner membranes and in animals it is located in the inner membranes of the mitochondria. The enzyme consists of 2 parts designated F1 and F0. The F1consists of 5 sub-units, designated 3, 3, , and . The F0 part on the other hand consists of 3 sub-units designated a, b and c. The stoichiometry of the a, b and c sub-units of the F0 is ab2c10-14(Hahn et al., 2016). The 2 parts of the enzyme complex, which includes F1 and F0 are connected to each other by 2 stalks, a central one and the other a peripheral one. The central stalk consists of the and sub-units, while the peripheral stalk comprises the and b sub-units. Interactions between F1 and F 0are said to be coupled and disruption of the interactions results in the loss of energy transduction and the system assumes an uncoupled state. Each of the 3 sub-units present in the F1consists of catalytic sites for ATP synthesis. The molecular interactions involved in the synthesis of ATP by the F1F0-ATPase was proposed by Paul Boyer and it was called the rotational catalysis mechanism or the binding change or alternating site hypothesis (Capaldi Aggeler, 2002). According to this mechanism or hypothesis, the 3 active sites of the F1 part of the enzyme complex participates in the catalysis of ATP synthesis. One of the sub-units binds ADP and Pi, thereby assuming the -ADP conformation. The sub-unit then assumes a -ATP conformation by tightly binding to ATP and bringing about an equilibration of both ATP and ADP/Pi on the surface of the enzyme. On assuming the -empty conformation, the sub-unit loses its affinity for ATP and as a result the newly synthesized ATP then is released from the enzyme complex. The next round of catalysis begins when the sub-unit again binds to ADP and Pi and assumes the -ADP conformation. During the catalysis reactions, the 3 sub-units interacts and assumes the conformations in such a way that one is in the -ATP conformations, while another is in the -ADP conformation and the third is in the -empty conformation. The conformational changes are brought about by the passage of protons through the F0 portion of the F1F0-ATPase. The streaming of the protons through the pore of F0, results in the rotation of the cylinder part of F0 composed of the c sub-units and the sub-units along its long axis. The rotation is about 120 degrees and results in the contact of the sub-unit with each and every catalytic sub-unit, thereby forcing them to assume the -empty conformations (Nelson, Cox Lehninger, 2012). Th ese conformations of the sub-units are also called the open, partly open and closed conformations, where the open conformation binds ATP or ADP/Pi. Binding of ATP and the closure of the open site, results in a conformational change of the remaining catalytic sub-units that results in the partly open sub-unit to attain the open conformation and the closed sub-unit to attain the partly open conformation (Capaldi Aggeler, 2002). Proton transport is dependent on the a and c sub-units of the F0 portion of the F1F0-ATPase. And the amino acid residues aspartate at position 61 of the c sub-units and Arginine at position 210 of the a sub-units are critical for carrying out the function of the proton transport. The rotation of the c sub-units takes place relative to that of the a sub-unit. The rotor stalk composed of the and sub-units are firmly attached to the c sub-units at the base, while interacting with the and sub-units at the top. The stator stalk consists of the b2 and sub-unit s, where the b2 interacts with the a sub-units and the interacts with the sub-units. Moreover, the arginine residue at position 376 of the sub-unit is involved in the generation of the transition state structure of the catalytic sub-units during steady state catalysis. The positive charge of Arg376 along with those of Lys155 and Arg182, results in the formation of a Pi binding pocket. Binding of Pi prevents the binding of ATP. Upon formation of the partly open -ADP conformation, the movement of the C- terminal region of the enzyme along with the nucleotide binding domain results in the re-positioning of the catalytic side chains, designated Glu181 and Arg182. Thus, this step involves priming of the catalytic site for subsequent catalytic steps. The next step involves transition from ADP/ Pi to ATP. This is brought about by the rotation of the sub-unit that results in the movement of the sub-unit towards the and the subsequent movement of the Arg376 and Arg182 towards ADP. Co-o rdination of a Mg2+ along with the residues Arg376, Lys155 and Arg182 brings about the synthesis of ATP. The sub-unit then undergoes further rotation resulting in the withdrawal of the Arg376 from the catalytic site, thereby causing the release of the ATP (Senior, Nadanaciva Weber, 2002; Martin et al., 2015).

(Source: Senior, Nadanaciva Weber, 2002) Figure 3: The various conformations of the catalytic site of the enzyme. (Source: Source: Capaldi Aggeler, 2002) Oxidative phosphorylation and photophosphorylation The oxidative phosphorylation is the metabolic pathway that is involved in the oxidation of nutrients in order to release energy in the form of ATP. Oxidative phosphorylation involves the occurrence of redox reactions with the help of which electrons are transferred to electron acceptors like oxygen from the electron donors. The flow of electrons is called the energy transport chain. The energy released is used in the transport of protons. Here the ATP synthase enzyme utilizes the energy of the proton gradient to convert ADP to ATP. It is the last enzyme of the oxidative phosphorylation pathway (Bazil, Beard Vinnakota, 2016). Apart from oxidative phosphorylation, photophosphorylation is another process that utilizes the ATP synthase enzyme to carry out phosphorylation of ADP to ATP during photosynthesis. Th transfer of electrons helps to generate a proton motive force that helps in the activation of the ATP synthase enzyme (Junge Nelson, 2015). Inhibitors The DCCD is the classical inhibitor of the ATP synthase. It functions by modification of the proton binding site present in the c sub-unit. It causes steric hindrance of the movement of the c sub-unit relative to the a sub-unit, thereby preventing the rotation of the F0F1 complex (Toei Noji, 2013). Conclusion Thus, it can be concluded that the ATP synthase is an integral part of the metabolism and energy production pathways of various organisms and the intricate molecular interactions of ATP with the enzyme complex constitutes the highlight of such an important metabolic reaction.
