Let me know if you can find any** * mass-mass conversions * **No clear examples. Let me know if you can find any** * Limiting Reactants * What is the Limiting Reagent The limiting reagent is also known as the limiting reactant. It is the reactant that limits the amount of product in a chemical reaction. Notice that the limiting reactant is the reactant that makes the least amount of product. * How do we find the L. R. * Example: * How many grams of N2 (g) can be produced from 9. 05 g of NH3 (g) reacting with 45. 2 g of CuO (s)? Create and Balance a Chemical Equation: 2NH3 (g) + 3CuO (g) N2 (g) + 3Cu (S) + 3H2O (l) 9. 05 g NH3 x 1 mol NH3 x 1 mol N2 x 28. 02 N2 = (7. 44 g N2) 17. 04 g NH3 2 mol NH3 1 mol N2 45. 2 g CuO x 1 mol CuO x 1 mol N2 x 28. 2 N2 = (5. 31 g N2 Less = LR Cuo is the Limiting Reactant! * Solutions * Morality – definition and how to calculate * Definition: * Amount of solute (in moles) per amount of solution (in Liters) * Molarity (M) = Amount of Solute (in moles) Amount of Solution (in L) * **Side Note** * Homogenous Mixture = solutions (Salt Water) * Solvent (a component in a solution) : Majority component, what something is dissolved in. (Water) * Solute (another component in a solution) : Minority component, what is being dissolved (salt) * Example: What is the molarity of a solution containing 3. 4 g of NH3 (l) in 200. 00 mL of solution? Given: 3. 4 g of NH3M = moles of solute (NH3) 200. 00 mL L of Solution (200. 00 mL) Convert: 3. 4 g NH3 X 1 mol NH3 = (0. 20 mols NH3) 17. 04 G nh3 200 mL X 1 L = (0. 2L) 1000 mL M = 0. 20 mols NH 3 / 0. 2 L = 1. 0 M NH3 **More examples in Notes! ** * Dilutions Calculations (M1V1 = M2V2, careful with M2) * Diluting a solution is a common practice and the number of moles of solute will not change! [ (M1)(V1) = (M2)(V2) ] * Examples: What is the concentration of a solution prepared by diluting 45. mL of 8. 25 M HNO3 to 135. 0 mL? M1V1 = M2V2 8. 25 M HNO3 X 0. 045 L = M2 X 0. 135 L 0. 135 L 0. 135 L M2 = 275 M HNO3 * Solution Stoichiometry * volume-volume conversions * When using morality, you can easily extract moles! * With a balance chemical equation, you can convert between amounts of substances. * Exampes: Look at notes OR page 145 TB * volume-mass conversions * Examples: Look at notes OR page 145 TB * **This wasn’t clear and If you know what this means, let me know. Or else I will ask Donavan on Saturday (Because there wasn’t a specific section for the two bullet points) Molecular interpretation of solubility * solubility rules – be familiar with the c hart/table that Prof. Donavan gave out 2 interactive forces that affect solubility: 1. solute-solute interaction 2. solute-solvent interaction if solute-solvent interactions are strong enough, solute will dissolve (solute-solvent interaction ; solute-solute interaction) * Precipitation Reactions * Determining reaction products General Form: AX (aq) + BY (aq) > AY (aq) + BX (s) Example: 2KI (aq) + Pb (NO3)2 (aq) >2KNO3 (aq) + PbI2 (s) * Following Solubility rules Molecular Formula, Total ionic formula, net ionic formula Examples: Molecular Formula: 2KOH (aq) + Mg(NO3)2 (aq) > 2KNO3 (aq) + Mg(OH)2 (s) Total ionic formula: * 2K+ (aq) + 2(OH)– (aq) + Mg2+ (aq) + 2(NO3)– (aq) > 2K+ (aq) + 2(NO3)- (aq) + Mg(OH)2(s) Net Ionic formula: (remove all spectator ions : ions that are aqueous as reactants and stay aqueous when they turn into products) Mg2+(aq) + 2(OH)-(aq) > Mg(OH)2(s) * Acid-Base Reactions General Form: HA (aq) + BOH (aq) > H2O (l) + BA (aq) Example: HCl (aq) + NaOH (aq) > H2O (l) + NaCl (aq) * Oxidation-Reduction reactions Oxidation is the loss of electrons * Reduction is the gain of electrons * Oxidation states: charges that allow us to keep track of electrons in chemical reactions * Identify oxidation states 1.

Collaborative Practice in Health Care Essay

Collaborative practice in health care occurs when a member of the health care team consults with another member to provide patient care. Collaboration most often occurs between doctors and nurses. â€Å"Collaboration is defined as a relationship of interdependence; the ability to work together involves trust and respect not only of each other but of the work and perspectives each contributes to the care of the patient† (Phipps and Schaag, 1995, p. 19). Effective collaborative practice amongst all health care team members leads to continuity of care, professional interdependence, quality care and patient satisfaction and decreased costs. Ongoing collaboration between health care members results in mutual respect, trust and an appreciation of what each individual brings to the overall goal in rendering care to the client. The following vignette will provide the foundation for the discussion of collaborative care, differentiating between nursing diagnosis and collaborative proble ms, and potential barriers to successful collaboration. JG is a 74 year old married Hispanic male diagnosed with colon cancer. He had a history of prosthesis placement of his left lower leg; he is ambulatory. He is a diabetic on oral medications. He worked as a farm laborer. He lives with his wife she does not speak English she is a homemaker. He has a son who lives nearby and a nephew who periodically visits him. JG can understand some English. He does have some difficulty expressing his health concerns to the staff because of his limited vocabulary. His son or nephew brings JG to his clinic appointments. He receives weekly chemotherapy at the outpatient oncology clinic. The day I cared for JG he arrived at the clinic accompanied by his nephew. This was week seven of his treatment. His clothing was dirty, he smelled of stool, his fingernails were dirty, hair uncombed, he appeared to be dehydrated. He reported bowel movements of eight stools per day with complaints of occasional abdominal cramping. He denied nausea or loss of appetite. He stated that he was very tired and was not able to do much at home. His main concern was the frequency of his bowel movements. He reports having to go to the bathroom two to three times during the night and has episodes of soiling the bed. He reports that sometimes he does not feel the  urge to go. JG was wearing adult diapers. He expressed concern that it was getting expensive for him to purchase. The nephew confirmed that JG toileting has created a problem in the home. His nephew verbalized that JG had medication for diarrhea but ran out of it and he did not have the money to purchase the medication. When questioned why he was using a wheelchair he stated that his foot hurt to walk the distance from the lobby to the treatment room. He mentioned that it was probably due to an ingrown toe nail. He also asked how he could obtain a wheel chair for his personal use at home. Physical assessment revealed that he had a necrotic area on the ball of his left foot with surrounding redness, lost 12 pounds in six weeks, poor skin turgor, hyperactive bowel sou nds, and his blood pressure was slightly lower than baseline. In the ambulatory chemotherapy setting, the clients do not always see their physician every time they receive treatment. The nurse must ascertain when to collaborate with the physician on issues regarding the patients status, response to treatment, or toxicities that may be life threatening. It is essential that the nurse is capable to communicate effectively her-(Be careful with gender bias, nurses come in both genders.) observations to the physician. Collaborative problems are detected from the nurse’s assessment of the patient. The nurse’s monitoring of the patient status is to evaluate physiological complications that may threaten the patient’s integrity. Management of collaborative problems will include implementing physician prescribed and nurse prescribed actions to curtail escalation of the problem and preventing patient harm. From the nurse’s assessment, she also formulates a nursing diagnosis. The nursing diagnoses are stated in the form of the problem, the etiology and the symptoms that the nurse observes. Nursing diagnosis can include a current or potential problem, an at risk problem, or a wellness diagnosis. Nursing diagnosis provides the framework from which the nurse begins to devise a plan of care and nursing interventions. In the case of JG, there were two collaborative problems identified. Two  problems I collaborated with physician, these were: 1. JG is experiencing toxicity from the chemotherapy. There is potential for electrolyte imbalance, circulatory collapse. 2. The necrotic area on his foot was a new development in his condition. There is potential complication for infection The collaborative problems discussed with JG physician and nurse quickly resolved. JG did not receive his chemotherapy. He was given an injection of sandostatin LR to help minimize his diarrhea; a stat basic metabolic panel was obtained; and he was given intravenous hydration with potassium. The doctor made a referral to JG podiatrist for the next day to assess the integrity of his left foot. Listed are four, but not all, possible nursing diagnosis obtained from my assessment. 1. Diarrhea related to chemotherapy manifested by hyperactive bowel sounds and eight loose stools. 2. Bowel incontinence related to loss of rectal sphincter control and chemotherapy manifested by fecal odor, fecal staining of clothing, urgency. 3. Altered Nutrition related to colon cancer manifested by diarrhea, abdominal cramping. 4.Ineffective management of therapeutic regimen related to JG lack of knowledge of his disease manifested by his inability and unwillingness to manage his symptoms. Considering JG comments regarding his finances, his overall physical appearance and the comments from his nephew, I decided to consult with the social worker. I felt that a home visit or a thorough investigation of JG home situation was warranted. The social worker was able to arrange for in home support, and helping the patient with insurance issues so he could obtain the needed supplies. I did not think to enlist the participation of the dietician. In retrospect, the dietician would have been a valuable resource to assess JG caloric intake and recommendations for optimal nutrition. I felt that the above incident demonstrated collaboration amongst health care providers. The physician in this case was receptive to the nurse’s observations with respect to her capabilities of accurate assessment of the patient’s condition and potential complications. This is not always the case, barriers to collaboration are also inherent in the health care industry. Barriers occur in patient situations where the physician is not sympathetic or does not trust the nurse’s evaluation of patient condition. The nurse may have feelings of inferiority, lack of confidence and does not appropriately collaborate with the physician correct information. Conflicts in the goals desired for the patient is often cited as a barrier to collaboration. I recall an incident of a male patient diagnosed with metastatic breast cancer. His appearance was that of an individual who had been in a Nazi concentration camp. The nurse wondered why the physician was treating this man aggressively. In her mind, this patient was not an appropriate candidate to receive the particular treatment that was ordered. She feared the patient would not tolerate such an aggressive schedule and that it was pointless to put this poor man through treatment. The patient was diagnosed two years ago. He is still receiving treatments, he has gained weight and in October of last year he hiked to the summit of Mt. Whitney. Role conflict is another major barrier to collaboration. To deliver cost effective care, many institutions utilize nurse practitioners and physician assistants. Role conflict arises when practitioners have opposing views or expectations (Blais, Hayes, Kozier, & Erb, 2002). Role conflict and can lead to litigation. According to Resnick, physicians hesitate to collaborate informally with Nurse Practitioners for fear of being held liable for the actions of the Nurse Practitioner (Resnick, 2004). Clear definition of roles  for practitioners is essential to prevent misunderstanding. In conclusion, collaborative practice is the gold standard that health care practioners should strive towards. The nurse is central in determining the patient issues that warrant collaboration and she must be able to effectively communicate her observations. Collaborative practice minimizes complications that could lead to tragic outcomes. The ultimate goal of collaborative practice is to provide the quality service that each patient under our care deserves. References Blais, K.K., Hayes, J. S., Kozier, B. & Erb, G. (2002).

Analysis Of Hamlets Isolation English Literature Essay

Analysis Of Hamlets Isolation English Literature Essay Many works reveal existentialism as a philosophy towards life. Someone who believes in this philosophy tends to become lonely, as one of the key concepts of existentialism is that we are alone. As demonstrated in Shakespeare’s tragic play, Hamlet’s attempt to come to terms with his existence pushes him to the edge as his loneliness overwhelms him. His soliloquies show elements of existentialism, revealing his turmoil of spirit and developing his character as being increasingly isolated. In Hamlet’s speeches, we see that he is an existentialist. When the ghost appears to Hamlet of his father passed, Hamlet is horrified. This encounter further pulls Hamlet away from reality as the ghost fills his head with ideas and a mission; Hamlet will revenge his father and kill Claudius. Claudius is revealed to us as being a hostile social force when the ghost comments, â€Å"The serpent that did sting thy father’s life / Now wears his crown.† (1.5.39-40). He re fers to his murder being committed by Claudius, Hamlet’s uncle. Hamlet admits that â€Å"à ¢Ã¢â€š ¬Ã‚ ¦memory holds a seat in [his] distracted globeà ¢Ã¢â€š ¬Ã‚ ¦Ã¢â‚¬  and that he must â€Å"à ¢Ã¢â€š ¬Ã‚ ¦wipe away all trivial fond records, / all saws of books, all forms, all pressures past, / That youth and observation copied there;à ¢Ã¢â€š ¬Ã‚ ¦Ã¢â‚¬  (1.5.97-102). By this, Hamlet means that he must do something about his life path and not dwell in the past. This resolve suggests the importance of the present. Hamlet is aware of the importance of acting on his impulses now because he realizes that something like pain can be easily forgotten. He wants the revenge to be as meaningful as possible to exact his vengeance properly. Estrangement from oneself can occur in many different forms. Hamlet’s thoughts and actions are disconnected. His mind is telling him to take revenge and kill Claudius, but his body does not obey him. He is in constant turmoil and contra diction with himself which brings him to be separated in his intentions versus his operations. This estrangement is disadvantageous to Hamlet in completing his task. Hamlet chastises himself for his failure and procrastination in regard to his father’s murder. In the observation from another of Hamlet’s soliloquies, â€Å"The spirit that I have seen / May be the devilà ¢Ã¢â€š ¬Ã‚ ¦. Out of my weakness and my melancholy, / [He] abuses me to damn me. I’ll have grounds / More relative than this. The play’s the thing / Wherein I’ll catch the conscience of the king.† (2.2.596-603) Hamlet doubts his father’s ghost’s credibility and is further isolated from those around him. His resolve makes him focused on this mission and Hamlet’s relationships with others suffer. The relationship with Claudius was already on edge, but Hamlet pushes him even farther away as he plots to kill him. The famous quote â€Å"To be, or not to be: t hat is the questionà ¢Ã¢â€š ¬Ã‚ ¦Ã¢â‚¬  (3.1.57) reflects on the human condition. Hamlet views the world in a different way than the other people around him. He realizes that people are alone and that things are not always as they seem. His insight scares and baffles other characters who interact with him. This is why Ophelia is also pushed away as Hamlet struggles with his inner turmoil and isolates himself from not only his mother and new king, but his girlfriend and love interest as well. This also reveals the absurdity of life. At this point in the play, Hamlet’s madness is being contributed to rejection of Ophelia’s love. This absurdity is only revealed to the readers of the play who have insight into Hamlet’s mind and intentions through his emotional soliloquies. The absurdity is further shown as Hamlet reflects on ending life. He describes the relief of dying, of leaving this world of pain and discomfort. However, one can never know what follows death a nd the fear of this prevents us from finishing ourselves off without living as much of this life that we can. Hamlet’s observation of this human condition remains absurd in our belief in it and our willingness to hold on to what we know.

Negligent Tort Research Paper Example | Topics and Well Written Essays - 750 words

Negligent Tort - Research Paper Example Elements of a negligent tort To file a successful case of unintentional tort, it is the duty of the plaintiff to prove that the defendant owed a duty of care towards the plaintiff. Duty of care refers to an individual’s obligation towards another individual to minimize and remove all foreseeable and avoidable risks (Miller, 2007, 95). A negligent tort case can be filed against a person if the individual is inattentive, fails to foresee an avoidable risk and, therefore, is unable to eliminate that risk. For example: if an individual holds a party on his property, it becomes his duty to inform the guests of all the negative and positive effects of attending the party and it is his duty to ensure that all the potential and avoidable risks are eliminated. The second element of unintentional tort is the breach of duty of care by the defendant, whether the defendant has breached his duty of care depends on the factual evidence of the case. In a tort case, the defendant is compared t o a reasonable person, if the defendant has not acted as a reasonable person should have, he is considered to be liable. The law helps the plaintiff in identifying whether the defendant has breached his duty. ... If harm has been caused, then it is obligatory for the defendant to compensate for the loss. The fourth element is the proximate and actual cause and effect relationship between the loss faced by plaintiff and the unintentional harm caused by the defendant. Actual cause and effect relationship refers to the fact that the harm was actually caused by the defendant to the plaintiff. For example: a huge number of accidents take place every day, sometimes those not involved in the accident become victims due to bad luck or negligent behavior by the victim, in such cases, the defendant cannot be held responsible in the case of negligent tort. Proximate cause refers to whether the defendant should be held responsible for negligent behavior according to fairness, practicality, rule and common sense. Remedies According to the law, there are different kinds of remedies when the plaintiff is successful in proving a negligent tort case. Remedies include; compensatory remedy, according to compens atory remedy, the plaintiff is to be compensated for both emotional as well as monetary losses (Walston-Dunham, 2012, p.227). Emotional losses include pain and hurt and monetary losses include loss of wages or property. Emotional damages fall under the category of General losses and monetary losses fall in the category of compensatory damages. The defendant may even have to pay for the replacement of loss in case of compensatory damage. These remedies are used both in intentional as well as unintentional torts. In severe cases and mostly in cases of intentional tort, the defendant may even face punitive damages; punitive damages may include punishing the individual who has been held accountable for

Anthropology Questions essay Example | Topics and Well Written Essays - 1500 words

Anthropology Questions - Essay Example In contrast, social authority is the capacity to command individuals. However, the two basic features of cultural authority, legitimacy, and competency must be attained collectively as one group (Joralemon 18) Whilst people may acquire confined reputation, a profession’s aggregate conveys significant trust warrant and authority. Legitimacy is attained by competent advance of national health. For example, health professionals can provide credible data, recommend and validate medical claims, and should be leaders and be honest always. Social authority is the most suitable in western Biomedicine since most of the communities are driven by superiority complex and a command can work well for them. Question 2 Cultural competence is referred to as a set of harmonious behaviors, policies, and attitudes that merge in an agency, among professionals, or system and enable that system, professions, or that agency to work efficiently in cross-cultural circumstances. Culture in this context is used with a reason that it applies the incorporated pattern of human behavior inclusive of communications, customs, values, thoughts, actions, and institutions of an ethnic, racial, social, or religious group. Competence is a word used here as it implies having the ability to function effectively (Bae 47). In terms of operations, Joralemon defines cultural competence as the combination and transformation of knowledge concerning groups of people and individuals into specific policies, standards, attitudes, and practices used in suitable cultural settings to improve on the quality of services, thus producing better results. Medical anthropologists apply the concept of cultural competence by incorporating dialogue at individual levels, since individuals are the ones who create and endorse culture, who encounter diseases and illness, and who can clarify the variation within what we comprehend as cultures. Dialogue recognizes that culture is not necessarily language, ethnicity, and co mmon tradition as existing discourse suggest, rather that these elements join with political and socioeconomic stratifications to affect individual experiences. Medical anthropologists assume that culture labels the entirety of an individual’s experience of illnesses and continues to show patients how important cultural competency is in giving the most effective and comprehensive medical care for all patients. However, the greatest challenge in their work is that, cultural competence is considered as a technical skill, which can be merely acquired or a matter that can be simply handled by a translator. This challenge is rooted from how medicine defines culture, which contrasts with its present use in anthropology. Culture is regularly made identical with nationality, language, and ethnicity. For example, cultural competence has do’s ad don’ts, which define how to take care of a patient from a specific ethnic background. In a medical setting, cultural competence is an important concept as it equalizes power dynamics in health care that lead to those with limited power, for example those in cultural, linguistic, ethnic, or economic minority to receive a lower quality care. It also helps health providers not to believe that they have a superior and correct value system. For example, some cultures believe that when death is talked about, it accelerates life loss, yet most western health care providers view this as a wrong belief

Deciding what is wrong and Right Essay Example | Topics and Well Written Essays - 1250 words - 2

Deciding what is wrong and Right - Essay Example The moral sense pertains individual particular emotional act. An act is right if the agent during the moment of action feels emotional approval towards an action. In this sense, one tends to perform an act that he or she approves. One abstains from an action that the person disapproves. Some emotions are called approval and others disapproval. In most instances, there must be some level of truth in the choice one take. Another judgment of approval may or may not be right. Scholars like Aristotle, Plato, Kant, and Mill touches on the right or the wrong act as understood in ethics. Aristotle, Plato, Kant and Mill in their works talk at different levels of making the right decision. Aristotle represents virtue ethics. Kant talks about duty ethics. Mill discusses utilitarianism. The four writers dwell on morality in their search for the right actions or highest good. Aristotle’s view is in self-sufficiency in the fulfillment of the ultimate desire. He emphasizes the conformity with the personal virtues. He regards happiness as an activity of the soul in accord with the perfect virtue. To him, people have to behave right to achieve happiness. As Plato’s student, he loved to categorized things. Aristotle argues that for our actions to be moral or immoral, right or wrong, we must have a certain level of health and wealth. He adopted a scientific and empirical approach to the problems resulted from ethics. Happiness to Aristotle is achieved by acting moderately. What is good for one person may not be right for another person. The use of reason alone may not define what is best for him. Plato, Aristotle’s teacher, states that the good or right is of the knowledge, and the evil or wrong is from the lack of knowledge. Therefore, a question of a good act is purely intellectual. He argues that there is only one right course of action.

Karaoke machine circuit based in transistors+ graphic equalizer Essay

Karaoke machine circuit based in transistors+ graphic equalizer - Essay Example The circuit will include following essential elements 1. Two inputs, 1 for microphone and a second for Line input, which could be mixed and boosted with a common emitter amplifier stage. 2. A six-band graphic equalizers stage. 3. A common emitter voltage boost amplifier stage. 4. A common collector power amplifier. 5. Circuit works from mains power supply. Circuit Operation Detailed circuit operation is given as under:- Power Supply The power supply is connected to pre amplifier and power amplifier blocks. The Transformer T1 is a simple step-down transformer which takes 240 V Ac current and gives out 9.5 V Ac at current rating of 1.3 amps approximately. The circuit requires steady DC current therefore output of transformer is applied to rectifiers. Transformer works on the principle of mutual induction of two coils. When current in the primary coil is changed, the flux linked to the secondary coil also changes. Consequently, an EMF is induced in the secondary coil. The transformer T1 consists of a rectangular core of soft iron in the form of sheets insulated from one another. Two separate coils of insulated wires, a primary coil and a secondary coil are wound on the core. These coils are well insulated from one another and from the core. The coil on the input side is called Primary coil and the coil on the output side is called Secondary coil. According to Faradays law EMF induced in a coil depends upon the rate of change of magnetic flux in the coil. If resistance of the coil is small then the induced EMF will be equal to voltage applied. A transformer in which Number of turns in primary coil are greater than Number of turns in secondary coil (Np>Ns) is called a step down transformer which is T1 in this case. In this way the Step down transformer T1 converts high alternate voltage of 240V to low alternate voltage of 9.5 V with current rating of 1.3 amps approximately. This voltage is next passed on to a rectifier to obtain a steady DC voltage. Rectifier D1 con sists of four diodes which are meant to convert Ac into DC. During each half of current cycle the diodes block reverse current and allow forward current. Rectifier D1 is a full wave rectifier which works during both positive and negative cycle of AC. Rectification is the conversion of alternating current (AC) to direct current (DC). This involves a device that only allows one-way flow of electrons and it is built around a four-diode bridge configuration therefore called a full-wave bridge or rectifier .Regardless of the polarity of the input, the current flows in the same direction through the load. That is, the negative half-cycle of source is a positive half-cycle at the load. The current flow is through two diodes in series for both polarities. Rectifier bridge works half time during positive sinosidal wave and half time during negative sinosidal wave. The result is a steady DC current measuring 9.5 V. This current is applied to Capacitor C18 with value 2500 uf, which charges the in put to around 13.5-14V peak voltage. This voltage is passed to a standard 12 V regulator IC1 that gives steady DC output of 12 V to run the complete circuit. In the power supply, heat is dissipated during transformer and voltage regulation stages. The capability of a capacitor to store electricity is known as capacitance of that capacitor. It is denoted by C. The measuring unit of capacitance is Farad, but Farad is very large unit. Its smaller units are Kilo Micro Farad (KMFD), Micro

Ways To Increase Return On Assets Essay Example | Topics and Well Written Essays - 2000 words

Ways To Increase Return On Assets - Essay Example Since both sets of figures show similarity in the total expenses at  £15,400 each, although Set B fails to present the break down of the expenses, then using the said expenses as criterion could not be deemed to indicate a material difference for purposes of inferring which of the two would or would not show a true and fair value. It is, therefore, the matter of the closing stock that will settle the issue of which set does or does not present a true and fair view since it is in the value of the closing where the two sets of figures materially differ. By taking the difference of  £14,000 and  £10,000, one will get a difference of  £4,000 which represents about 40% and which could be now considered by auditors as material misstatement in the financial statement. As to why it affects materially the financial statements will be seen in the income statement and the balance sheet. The income statement is affected because closing stock or inventory takes the nature of revenues in t he income statement as will be explained later. The balance sheet is also affected because the closing stock is part of the current assets and total assets which are parts the computation of liquidity using current ratio and the profitability using the return on assets. Since it affects the net income, the other ratios where net income is used will also be affected.  As to how the material misstatement will affect the profitability ratios may be illustrated as follows: First, the closing stock is important in the computation of gross profit ratio (GPR) which is computed by dividing gross profit by the total sales. It must be noted that the closing stock affects the value of the cost of sales to be deducted from total sales to arrive at the gross profit.

International Asia Pacific Business - Essay Example hile formulating the strategies, the organizations’ leader and the management team will firstly look at the factors that may aid them to make a successful entry. After analyzing the positive factors, the firms will or should have to analyze the challenges that may impede its entry. As every foreign market or country will have different political, social, economic conditions as well as different customers, competitors, prospective employees, etc, etc, there will be many challenges, which will block the firms’ success. Also, there will be country specific challenges as well as industry specific challenges in those foreign markets. For example, the Asian country of China has some distinct aspects, which will surely act as a challenge for the new firms, who are planning to enter it. Likewise, the retail industry in China also has some inbuilt challenges, which may impede the foreign invested retail firms, who may plan to make an entry into China. So, this paper will analyse and asses the challenges faced by Foreign invested Retail firms in China. In the earlier decades, the cheap Chinese products only entered various countries’ markets. But, now seeing the potential of the Chinese economy and the market many foreign firms or foreign invested firms have entered or entering the Chinese markets. The other thing, which is enticing the foreign firms including the retail firms, is the huge population, which translates into the biggest market of the world. â€Å"Most of the world’s major global retail firms are desperate to grab a slice of the world’s largest and most rapidly growing emerging market† (Gamble, 2006). Apart from these two important aspects (high economic growth and huge market), the main thing that allows the foreign firms to enter China including its retail sector is the relaxation of many restrictions imposed by the Chinese Government. China being a Communist country functioned behind an â€Å"Iron Curtain†, restricting the foreign firms to protect

Successful andor unsuccessful application of organizational behavior Essay

Successful andor unsuccessful application of organizational behavior concepts in any organization - Essay Example Concepts that are inevitably connected with organizational behavior are those which have a direct impact on the above corporate objectives of the organization. The most common among these concepts are the organizational culture, effectiveness, diversity, learning, efficiency and communication. Wal-Mart has been well known for its unique Human Resource Management (HRM) practices, extremely democratic organizational structure/culture and highly successful employee motivation strategies. Organizational culture consists of both the individual and collective characteristics of the employees within the organization. "Organizational culture is a pattern of knowledge, belief, and behaviorit is the form, beliefs, norms, social patterns, the way things are done, the symbols and rituals" (Burton, Lauridsen, & Obel, 2004). Organizational behavior and its associated concepts of Wal-Mart have to be examined against its HRM practices, organizational structure and employee motivation strategies which in turn depend on other variables such as the impact of globalization on the business, government rules and regulations, market demand for and supply of factors of production such as labor and the level of competition. The geographical and occupational mobility of labor also matters. Wal-Mart with a workforce of roughly 2.1 million is the biggest public company in the world by revenue, i.e. US $400 billion (approximately) in 2008. These staggering figures apart the giant grocery retailer has been looked upon as the model American business organization by many analysts and industry experts.Theoretical underpinnings about organizational behavior and the related concepts have been evolving over the years from Taylor's scientific management theory, through human relations theories and theory X and theory Y people to the modern day behavioral theories. This historical delineation signifies a number of aspects about the conceptualization of organizational behavior in the modern business context. Thus a particularly important aspect of leadership research in the sphere of organizational behavior is focused on Social Identity Model of Organizational Leadership (SIMOL). SIMOL is currently in vogue for the sole reason that it serves not only as a behavioral approach to organizational culture but also as a contingency model to study leadership (Kramer and Staw, Editors, 2003, p.283). Its relevance to this analysis lies in the correlation between the organizational behavior concepts such as organizational communication and diversity and corporate objectives such as profits and market share.Next theoretical postulate which has a significant bearing on organizational behavior concepts is the leadership style and the latter with a considerable amount of complexity applies to a variety of business cont exts. For instance leadership style in Wal-Mart is characterized by a degree of democratic delegation of freedom to the staff to take decisions at the operational level. This aspect of the organization is subject to critical analysis for it obviously presumes that organizational behavior engenders a series of culture-centric responses to the external strategic environment including that of competitors' behavior. Corporate strategy in this particular context plays

Lennie is mourning the death of his puppy Essay Example for Free

Lennie is mourning the death of his puppy Essay At the beginning of the extract, Lennie is mourning the death of his puppy by his own hand when Curleys wife enters the barn and attempts to comfort him and she allows Lennie to stroke her hair. When Lennies big fingers fell to stroking her hair we see that something is going to happen as the mood changes and the tension is heightened. We have an inclination to what is about to happen as we have seen the inevitability of the scenario with Lennies strength and Curleys wifes desire for affection and attention. When Curleys wife tells Lennie not to muss it up, Lennie strokes harder, as he is overcome with the pleasure of the experience, this shows that Lennie doesnt listen to anyone except from George, thus reinforcing what we already know. Curleys wife says you stop it now and jerks her head sideways and Lennie then panics and automatically his fingers close on her hair and hung on, this is because it is the only thing he can think to do, this emphasises his child-like mentality as his reaction is physical as opposed to psychological. Lennie was in a panic and his face was contorted, these two short simple sentences portray the innocence and naivety of Lennies actions as well as reflecting the way Lennies mind works, short and simple. He begs Curleys wife to stop screaming because Georgell be mad and aint gonna let him tend no rabbits showing that he has a one-track mind, much like a child. Lennie then gets angry and tells Curleys wife I dont want you to yell, this again shows his child-like mindset and his anger leads him to shake her. So hes shaking her, not in an aggressive manner, but to protect his part in the dream, her body flopped like a fish and she was still, for Lennie had broken her neck. At this point we see Lennie, not just kill Curleys wife, but kill the dream too. Lennie does not realise he has killed her as he continues to speak to her, he lifts her arm and lets it drop and is, for a moment, bewildered. His mind cant capacitate why she is not responding, all he thinks he did was shake her, showing just how unaware he is of his own strength. Animal imagery is used to describe how Lennie pawed up the hay until it party covered her, this connotes Lennies clumsiness and density. In the concluding paragraph of the extract we see Lennie become conscious of the outside for the first time, he recalls what George told him to do if he gets into trouble and goes to hide in the brush, taking the dead puppy with him to throw it away because its bad enough like it is. Here we see Lennie make a decision himself, be it the right one or not, he seems to have matured slightly because of the situation at hand and this event could be something that changes Lennies childish behaviour. Throughout the death of Curleys wife, we still feel more sympathy for Lennie, because he is so unaware of the danger his actions can cause and he is still a naive and innocent character, despite the unintentional harm he has brought to many things.

Four Traditions of Geography Essay Example for Free

Four Traditions of Geography Essay Four Tradition of Geography The Four Traditions of Geography has many different assumptions and aspects of geography; aspects ranging from basic mapping and geometry, to the impact on nature of humans and the processes of the earth itself. Geographers can study and explain their research by selecting a certain tradition that leads to many different fields of geography. â€Å"There are four traditions whose identification provides an alternative to the competing monistic definitions that have been a geographer’s lot† (Pattison 1964). The following discussion treats the traditions in this order: (1) a spatial tradition, (2) an area studies tradition, (3) a man-land tradition and (4) an earth science tradition† (Pattison 1964). Pattison is exploring all the categories of geography and he is explaining how these different traditions can uncover the meanings of different studies of geography. â€Å"Going further one can uncover the meanings of â€Å"systematic geography,† â€Å"regional geography,† â€Å"urban geography,† â€Å"industrial geography,† etc. † (Pattison 1964). Spatial tradition is an area of concentration that relies on geometry and movement. It also is the study of mapping as seen in the ancient Greece recordings of such, and it also deals with the GIS system. GIS is any system that captures, stores, analyzes, manages, and presents data that are linked to a location. It explores the central place theory and how it is used in geography. Central place theory is the geography theory that seeks to explain the number, size and location of human settlements in an urban system. Area Studies, just like the spatial tradition it has roots from many, many years ago. The Greek philosopher, Strabo, wrote an encyclopedia about geographical knowledge. â€Å"He is Strabo, celebrated for his Geography which is a massive production addressed to the statesmen of Augustan Rome and intended to sum up and regularize knowledge not of the location of places and associated cartographic facts, as in the somewhat later case of Ptolemy, but of the nature of places, their character and their differentiation† (Pattison 1964). The area-studies tradition was tended to be excluded from early American professional geography. Today, it is beset by certain champions of the spatial tradition who would have one believe that somehow the area studies way of organizing knowledge is only a subdepartment of spatialism† (Pattison 1964). It concentrates on the descriptions of regions in order to differentiate them from other regions and areas. Being able to understand geography in these terms can reveal the deepest knowledge of the world’s environment. The Man-Land tradition describes the human impact in nature and also the impact of nature on humans, and it also defines the nature disasters our world takes on. Social Darwinism simply grabbed a theory from the biosciences and applied it to social happenings without the lengthy process of trial and error for social data which led to environmentalism. Environmentalism is a broad philosophy and social movement regarding concerns for environmental conservation and improvement of the environment. Man-Land gives us the basic perception on the environment and what is happening to it. The earth science tradition, embraces the study of the earth, the waters of the earth, and the atmosphere surrounding the earth and the association between the earth and the sun† (Pattison 1964). On two different hands of the topic, it is being used and then it is not being used. â€Å"On one hand, it is not always elected as the best tradition as it has been decreasing in use from past decades, while on the other one knows that college departments rely substantially, for justification of their role in general education, upon curricular content springing directly from this tradition† (Pattison 1964). It also acknowledges the human impact on the planet but mainly focuses on the planet itself and its physical processes. Geology, mineralogy, paleontology, glaciology, and meteorology all have rooted out of these studies. From reading â€Å"Four Traditions of Geography† and â€Å"In Search of Synthesis,† Area Studies tradition is my personal preference on this matter. Gober talks about the many different specialties that lie in between human and physical geography, and I grasped that I am more of a physical, on-hands doing person. With human geography you study societies as a whole and I am more interested in urbanization of the earth and how we can use the land we have in a fashion that is basically perfect. I am interested in the different regions because I am really fascinated in real estate and I figure I would learn a whole lot about the physical aspect of geography. I feel that I could really excel in real estate with this kind of learning. The Four Traditions of Geography has different definitions and aspects of geography. With the information given, people are given the opportunity to understand what geography is all about and be able to break geography down and select a certain practice from the very selective topic. â€Å"It is hoped that through a widened willingness to conceive of and discuss the field in terms of these traditions, geography will be better able to secure the inner unity and outer intelligibility† (Pattison 1964). William D. Pattison, The Four Traditions of Geography, (1964).

Somatic Cell Nuclear Transfer Process

Somatic Cell Nuclear Transfer Process Attempts at cloning a mammal can be traced back to 1979, where the scientist Steen Willadsen successfully cloned a sheep embryo using nuclear transfer [1]. Since then numerous attempts have been made to replicate these results. Notably the birth of Dolly the sheep (1996) was a major development in this field; as she was the first mammal to be cloned from a fully differentiated somatic cell, using somatic cell nuclear transfer (SCNT) [2]. This essay will describe the process of somatic cell nuclear transfer in light of mammalian cloning and the risks it poses to mammalian reproduction. The fertilization of mammalian gametes through natural reproduction is limited by the ability to preserve desirable traits after the extinction of an individual. Moreover, the reproductive success of natural fertilization is limited by the gestation length, estrus cycle, the efficiency of insemination during intercourse and Hayflick limit [3]. Furthermore, these limitations are chiefly important in livestock agriculture; where desired traits and alleles are more favourable for propagation. SCNT enables us to extract the nucleus of a fully differentiated somatic cell (diploid cells) and introduce it into an enucleated mature oocyte which is allowed to develop into an embryo; that is genetically identical to the host cell [4]. Other variations to this method are practised even though they all rely on the same principles. By this process, the limitations stated above become insignificant as specific mammals with the desired traits can be cloned to preserve the genome. However, this technique is still undeveloped and the success in producing cloned offspring is low. The success rate of SCNT is dependent on several factors; namely, selecting the right donor cell that will be most efficient to the nuclear transfer. In this process, fully differentiated somatic cells are selected based on their cell-cycle state and age. The G0 phase is most desired when selecting the donor cell as it has been shown to be the most effectual donor [5]. Conversely, deprivation of nutrient to the donor cells growing in vitro can also induce the cells to adopt the G0 resting phase. The age of donor cells also contribute to the success of cloning, the more aged the donor cell the less efficient SCNT becomes. Additionally, donor cells that are derived from more genetically diverse species are favoured, as it has been shown that cells obtained from inbred animals are less likely to be successful in cloning [6]. However, these factors are only relative to the limited species that have been examined and more factors may come to light as other species such as primates are subjected to SCNT. Once the donor somatic cells are identified, they are normally extracted from the skin of the donor mammal, using needle aspiration and avoiding unnecessary strain on the donor animal. Oocytogenesis is the process in which females produce oocytes. SCNT uses mature oocytes in metaphase-ll which are collected from the ovaries of the required animal [7]. The mature oocytes are enucleated using micromanipulation which penetrates the zona pellucida and removes the nucleus. There are two alternative routes which can be adopted when manipulating the process of the insemination of the nucleus donor cells into the mature oocytes. First, the Honolulu technique (developed by Wakayama) which uses brain cells, cumulus cells and sertoli cells as donors that are naturally in the G0/G1 phase. The nucleus of the somatic cell is aspirated and directly micro-injected into the oocyte using a piezo-impact pipette; which penetrates the zona pellucid and delivers the nucleus into the enucleated oocyte [8]. The oocytes are subsequently activated by exposing them to a medium containing Sr+2 that also contains cytochalasin-B which acts to prevent the formation polar bodies. Figure. 1[9] shows a diagrammatic representation of the Honolulu technique, highlighting that the nucleus is directly inserted into the mature oocyte. Secondly, the Roslin technique (used to create Dolly the sheep) cultures donor cells in vitro and deprives them of nutrients; forcing the cells to adopt the G0 phase. Subsequently, the enucleated oocyte is aligned next to the donor cell; such that the oocyte and donor cell are parallel to one another. Pulsating electrical currents are applied to fuse the oocyte and donor cell together, by inducing pore formation of the cell membrane [10]. Figure.1In the Honolulu and Roslin techniques the use of chemicals and electrical pulses induce the activation of the oocyte, which can subsequently develop into an embryo which is implanted into a surrogate host for progeny development. The activation of the oocyte induces major reprogramming of the differentiated donor nuclei back to its totipotent state [11]. This process is extremely intricate and the full biochemical mechanisms are not fully understood. However, extensive research has been completed in understanding an overview of oocyte reprogramming and epigenetic modification. The introduction of a somatic nucleus into the oocyte causes rapid deacetylation of histones on lysine residues, catalysed by histone deacetlase. Moreover, the donor chromatins also experience demethylation [12], which is also a method that is used to dedifferentiate the nuclei back to totipotent state. Aberrant or incomplete DNA reprogramming is thought to be a major contributor to abnormal development in embryos and clones which can explain why only 1% of SCNT are successful in producing fully developed clones. Figure.2The efficiency of the Honolulu technique and the success rate of cloning have been shown to be superior to the Roslin technique [12]. However, the overall success rate of cloning, irrespective of the method used is still considerably low, with only 1% success rate. Figure. 2 [13] shows the percentage of embryos surviving prior to implantation with surrogate and post implantation. Moreover, there are several risks associated with clones derived from mammalian SCNT. These risks also have ethical implications that follow. Phenotypic abnormalities that are associated with clones derived from SCNT ranges from aberrant telomere length (which can lead to premature ageing) to large offspring syndrome and irregular placenta development during embryonic growth. The telomere length and ageing of clones are thought to be directly correlated. Telomeres are situated on the ends of chromosomes and consist of numerous repetitive DNA bases that function to stabilise and prevent deterioration of the chromosome [14]. Experimental observations show that some species of mammals are prone to shorter telomere lengths in comparison with a control. It is also thought that the telomeres are not fully restored to the original length during SCNT. Such implications can suggest that the sizes of the somatic cell telomeres are inherited by the clones; therefore producing clones that have already aged [15]. Dolly lived until she was 6 years of age (half the age of an average sheep) and was shown to have shorter telomeres in comparison to a control (19 kb vs. 23 kb) implying that she died prematurely. However, shorter telomeres in clones are not universally applicable as in mice, bovine and cattle all showed similar lengths to their respective control, if not lon ger [16]. The occurrence of shorter telomere lengths in some species suggests that the donor cell species and genetic background govern it. Nevertheless, the exact cause of short telomere length is still not yet fully comprehendible, yet some studies indicate that it might be caused by incomplete reprogramming [17]. Large offspring syndrome (LOS) is characterised by larger than normal clones that have oversized organs and aberrant limb formation which all can lead to an increase in prevalence of organ defects and cardiovascular difficulties. These characteristics have been observed in cattle and can contribute to higher abortions rate and deformities in skeletal structure. However, offspringà ¢Ã¢â€š ¬Ã¢â€ž ¢s derived from cloned mammals diagnosed with LOS, were shown not to have LOS [18]. This suggests that again irregular epigenetic reprogramming during SCNT is a contributor to LOS as the progeny of the clones (which are born naturally) fail to have LOS. Embryos that are derived from SCNT have been shown to have abnormal/enlarged placenta development (placentomegaly) during embryonic growth. The abnormalities occur in both bovine and mice [19] and can cause the developing fetus to die during pregnancy. The aberrant placenta in mice is shown to have an increased amount of insulin- like growth factor which can cause LOS in clones. Moreover, failure for the placenta to develop accordingly during the pregnancy of clones can cause immune-mediated abortion [20]. The risks to mammalian reproduction stated above can produce clones that are phenotypically defective which raises ethical concerns. The abnormalities in clones can cause harmful side effects and can lead to cloned mammals suffering. We have seen that some mammals show premature ageing which can ultimately lead to premature death. The welfare of these clones seems to be disregarded in the experiments that are conducted. Moreover, there are concerns that a small proportion of cloned animals can enter our food chain, which is thought to be unsafe. However, recent studies show that consumption of cloned animals is safe to homosapeins [21]. The prospect of human SCNT also has deep ethical implications. Current legislation in all countries prevents SCNT in humans. Nonetheless, the proposed benefits that SCNT offers (therapeutic cloning) may one day outweigh the ethical concerns. If this occurs, it would shake the foundations of tradition, as humans can be à ¢Ã¢â€š ¬Ã¢â€ž ¢producedà ¢Ã¢â€š ¬Ã¢â€ž ¢ asexually with their genomic sequence known [22]. This can lead to à ¢Ã¢â€š ¬Ã‹Å"gene discrimination by other non cloned humans, and by cooperate companies who can prevent human clones (that may be prone to specific dieses) from obtaining insurance, for example. In conclusion, Somatic cell nuclear transfer has been successfully used to clone mammals from fully differentiated somatic cell. However, this technique is largely inefficient and a major Impediment is that only 1% of somatic cells successfully developed into clone. The lack of understanding on oocyte reprogramming can be contributed to the inefficiency of this technique. Moreover, this has lead to some clones showing abnormal phenotypic features which has major ethical implications. Nevertheless, somatic cell nuclear transfer shows great promise in the fields of medical therapeutics, agriculture and conservation once all aspects of its process are understood.

john wilde :: essays research papers

Art History John Wilde Gallery Paper Well walking through the gallery the only piece that stood out to me was John Wilde's piece "A Tribute to the Rubber Stamp #7" a silver point on paper. The piece itself has a very simple composition that contains a hand coming into the page from the left side about about a third of the way up the page. The arm has a shirt on with a pinstripe jacket over it. On the right side of the page is a six banded armadillo with a snail with wings. These animals are placed in the right third of the page. Behind the hand is very light mountain forms that peaks right above the hand and slowly slopes down to pretty much the center of the page and flows fairly flat and parallel with the hand. The mountains are the only thing with a sense of color in the piece, they are washed with a very subtle brown wash. The only other thing that has any sense of color is the armadillos shadow and thats extremely minimal. The armadillo and snail seem to be pretty much proportioned properly except that the armadillos tail is a little to long and the back side of the nail is too big. I think the wings that are on the back of the snail looks exactly like the Detroit Red Wings emblem, minus the color. Everything seems to be drawn graphicly except for the mountains that are drawn fairly loose. The palm of the hand has very good detail and it looks fairly realistic even without any shading. The armadillo and snail are drawn very well, there's a good amount of detail like the tiny hairs that come out of the front of the armadillos she right under its face, and the scale of the armadillo are are very good. The mountains split the composition and give the piece a background and a foreground. The way the mountains go through the page makes the background go back into space and the foreground come forward even though all it is, is wide open white space. another things the mountains do is take your eye from the left side of the page and slowly guides them to the right side, the hand also aids the composition in this almost pointing you towards the right side of the page towards the animals.

The Definition of Literature :: Definition Essays

The Definition of Literature   Ã‚  Ã‚  Ã‚  Ã‚  Literature has many meanings but to me when I hear the word literature I think of large tomes of words and stories that have become classics over time however this is only one definition of literature. Literature comes from that Latin word littera, that directly translated means letter, thus supporting the idea that literature is written. This view however leaves out the idea that there can be oral literature as well from which many of our stories and books come from.   Ã‚  Ã‚  Ã‚  Ã‚  The main form of literature, the book, has had a great impact upon the formation of our society today. Before the 1940’s TV had not come into being yet and there was not much else to do other than read books. Thus books formed my grandparents and to some extent my parents and, although I grew up in the generation of TV, books as literature have indirectly formed me as well. There also can be forms of artistic literature such as poetry or play writing. These also play an important part in literature, I believe, such as Robert frost’s poems or the works of Shakespeare the playwright. These are great authors, whose literature is not in the form of a great story or a moving novel, but in irregular works that have stayed with us for a long time many years. I believe that one very good definition of literature is that literature must have certain qualities such as plot, characters, tone, symbols, conflict, point of view, and many other elements working together in a dynamic relationship to produce a literary work. This pretty much defines the way that most people see literature today. This allows for oral traditional stories as well as for the irregular forms of writing such as plays and poems that can also have plot, characters, tone and the other elements mentioned so that they can be deemed a literary work.

Breadcrafter’s breads Essay

This business plan is a tightly constructed, succinct consideration of all factors relevant to launching this bakery. From rent charges to competition and seasonal changes to costs per loaf, this plan hasn’t left anything out†¦all without being overly verbose. This exemplary plan is very focused and complete, which will help the business stay on course. Breadcrafter’s breads will stand out from the competition due to their uniqueness and outstanding quality. Most of the breads are European in style, including Sourdough, Miche (a traditional French whole wheat bread), and Sourdough Rye. These breads are made by the sourdough method which uses no added yeast. This method imparts a rich flavor, which can be tangy or mild, as well as a toothsome inner crumb and a crackly crust. By using this method, a skilled baker can create truly delicious breads without added fats or sugars, making many of Breadcrafter’s products 100% fat free. Sourdough breads also have an extended shelf life, remaining fresh for days without the use of preservatives. Breadcrafter will also offer specialty breads, which will be made in the sourdough way with the addition of such luxurious ingredients as Parmagian cheese with fresh ground pepper and dried Michigan cherries with roasted pecans. Spent Grain Bread, made with barley leftover from beer brewing, is another unique product that Breadcrafter will offer. Two varieties of French style baguettes will be offered fresh daily, a high demand product that is available nowhere else in the area. Breadcrafter will also produce White and Wheat Sandwich Breads with soft crust and a tender crumb for traditional American Style sandwiches. As the needs of the customer change, so will the lineup of Breadcrafter’s products. The bakery equipment is chosen with versatility in mind. After establishing the business, Breadcrafter will research the possibility of producing sandwiches to increase revenues. This investment would require approximately $1500.00 for the purchase of equipment and ingredients. The company will also pursue wholesale contracts. Toothsome Foods Company has indicated interest in a contract to produce two Christmas products on a per loaf basis, Cherry Chocolate Fruitcake and Midwest Christmas Stollen. These products can help generate revenues in the slower Autumn months. The proprietor will also consider producing some of Toothsome Foods’ current lineup of Handmade Breads on a wholesale basis.

Rural vs. Country Living

Sean Stafford 11/11/12 Living Urban Vs. Rural The on-going debate of living in the city vs. country is very controversial in many people’s eyes but, the city has much more to offer economically, socially and in many other ways more convenient. Being able to meet your needs conveniently and to travel in a car less is what makes the city a lot easier to live in. Therefore, Living in the city is much more beneficial than living in the rural areas.Being able to walk around different places that offer different things to meet your needs specifically is something we could dream of, well in the setting of a city you are able to virtually walk anywhere and either takes a metro or taxi and you will arrive at your destination quicker than ever. Living in the city brings a sort of social structure in a way because when you live in the Country your nearest neighbor may be a mile away. There may be times when you won’t see another human being for days unless you go somewhere off of your property.And f you so much as run out of milk it means a trip in the car. Mechanics and most services are not close It is not easy if your car breaks down and your nearest mechanic is 30 miles away. Secondly, there are many kind of public transport such as train, tram, bus, taxi in the city and there are many streets. On the other hands, in the country they do not have many streets so therefore making the city transport system more complex but in a better way.Again the convenience in the city is better than the convenience in the country. It is easy to make more friends because people living in a city are more friendly and happier with their friends. On the other hand, in the country people are less open minded to make friends with someone they have never met. Another factor that has to do with the well being of a person is getting sick, and health in the city is better than in the country, In city there are many hospitals. Lastly,

Lot 6579, Gong Kepas Dalam Village, Alor Lintang,22200, Besut Terengganu,Malaysia. Dear Rowan Love, I'm so pleased to see your purple coloured letter in my mailbox this morning. (You put some raspberry shaped stickers on it! It smells great! ) So,you've been asking on how to take are of orphaned kittens right? Okay,this is based on my previous experience when I found a three week year old kitten in my school,I named her Gabby. (She is all grown up! ) Basically,you need KMR (Kitten Milk Replacer) or lactose free milk,a towel,tray,litter sand a syringe or cat milk bottle and wetfood. You may use dryfood but be sure to mix it with water if the kitten is below 2 months old. If the kitten shivers,wrap the kitten,not too tight or too loose and put it in your shirt as it cannot generate it's own heat. Next,feed the kitten with KMR and wetfood. Remember,never feed the kitten wiith cow milk or lactose containing drink because cats are lactose intolerant,If you insist,the kitten may suffering diarrhea which eventually leads to death. Second,create a kitten box,Just put a tray and litter sand and two layers of towels in a very big box or a medium-sized cage. Be sure to check the kitten's stool. It should'nt be too hard,too watery or with mucus. If it is consult to the veterinar immediately as the kitten may suffering a diarrhea. Okay,here's a few handy tips. If the kitten's medication is syrup,use a syringe to give t to the kitten. If it is in a pill form,crush it inside a plastic bag and mix it with wetfood. Do not force feed unless you need to. Alright,that's all for now,I hope that answers your doubt. Refer to the net if my information is not sufficient for you. From your BFF, Syakeera.

Fundamental Media

Mass communication research includes media institutions and processes such as diffusion of information, and media effects such as persuasion or manipulation of public opinion. In the United States, for instance, several university departments were remodeled into schools or colleges of mass communication or â€Å"journalism and mass communication†. In addition to studying practical skills of journalism, public relations or advertising, they offer programs on â€Å"mass communication† or â€Å"mass communication research. The latter is often the title given to doctoral studies in such schools, whether the focus of the student's research is journalism practice, history, law or media effects. Departmental structures within such colleges may separate research and instruction in professional or technical aspects of mass communication. With the increased role of the Internet in delivering news and information, mass communication studies and media organizations tend to focus o n the convergence of publishing, broadcasting and digital communication. The academic mass communication discipline historically differs from media studies and communication studies programs with roots in departments of theatre, film or speech, and with more interest in â€Å"qualitative,† interpretive theory, critical or cultural approaches to communication study. In contrast, many mass communication programs historically lean toward empirical analysis and quantitative research— from statistical content analysis of media messages to survey research, public opinion polling, and experimental research. Interest in â€Å"New Media† and â€Å"Computer Mediated Communication† is growing much faster than educational institutions can assimilate it. So far, traditional classes and degree programs have not been able to accommodate new shifts of the paradigm in communication technologies. Although national standards for the study of interactive media have been present in the U. K. since the mid-nineties, course work in these areas tends to vary significantly from university to university. Graduates of Mass Communication programs work in a variety of fields in traditional news media and publishing, advertising, public relations and research institutes. Such programs are accredited by the Accrediting Council on Education in Journalism and Mass Communication ACEJMC Questions a) Define and describe mass communication as a professional field giving examples of theories and criticism around this field (20 Marks) b) Give a brief history of the evolution of mass communication.

Hayek and alfred marshal Assignment Example | Topics and Well Written Essays - 500 words

Hayek and alfred marshal - Assignment Example While the price system has the disadvantages of its own, it’s should still be thought of as a marvel of the economically driven coordination. Hayek explains that the contrast exists between the natural and social sciences. In the sciences of the natural type, if advances are to be made, scientists should recognise that things are actually not what they might seem. Science undoubtedly dissolves the existing categories of subjective experience only to replace them with causes that are hidden and lie beneath the surface. Hayek believes that contrary to this principle the study of society ought to take to use as its raw material the subjective ideas and beliefs expressed by members of the society. To illustrate, Hayek says, â€Å"the position of man, midway between natural and social phenomena (...) brings it about that the essential basic facts which we need for explanation of social phenomena are part of the common experience, part of the stuff of our thinking† (Hayek 126). In brief, one should perceive the society in relation to the role of men’s conscious reflection of the done actions. While people in a soc iety are all the time choosing among a variety of choices of how to act, in a collective sense the outcome is an unintended result of decisions taken consciously. Central planning is a wrong way to shape the social economic order. Hayek is against centralization, when economic planning is carried out by one authority over the system, but thinks that this economic planning has to be distributed among many individuals. Based on his review of the Mise’s work, Hayek agrees that rational calculation, applicable to an economic order, has been made impossible by socialism the way Hayek saw it functioning in practice. Indeed, central direction of the overall economic activity at once at distribution of the income that is not dependent on private property in the situation when output is greater than production is doomed to failure. Yet,

BOOK REVIEW on Open Networks, Closed Regimes by Shanthi Kalathil and Essay

BOOK REVIEW on Open Networks, Closed Regimes by Shanthi Kalathil and Taylor C. Boas - Essay Example They also examined Governmental use of the electronic medium, while economically, they examined Internet use by domestic entrepreneurs. Lastly, they also examine the impact of informational technology from the perspective of how the use of the worldwide web outside the borders of a particular country could impact upon the internal political stability of these countries. The authors have concluded that the impact of the Internet is ambiguous, because in some countries authoritarian regimes have actually been able to cement their position, while in others the Internet has not made much of a difference. As a result they found no evidence to support the contention that the Internet threatens authoritarian regimes. The central thesis of the book is clearly stated at the very outset, as follows: â€Å"There is now a widespread belief in the policy world that the Internet poses an insurmountable threat to authoritarian rule.† (Kalathil and Taylor, 3 ). The authors set out to examine the veracity of this assumption and state clearly that â€Å"we seek to critically examine the impact of the Internet in authoritarian regimes.† Thus, on this basis, the thesis is clearly laid out as being the answer to the question of whether the Internet indeed poses a threat to authoritarian regimes and promotes the forces of democratization. This is also the sub title of the book. In order to address the thesis, the authors have explored patterns and content of Internet use in six countries with authoritarian regimes. In examining the patterns of Internet use and the levels of control or blocking imposed by the States in question, the authors have arrived at the conclusion that the so called threat to authoritarian regimes posed by the Internet is ambiguous, because the extent of its effect is also dependent upon various social and political factors and players. In some instances, authoritarian regimes were actually able

JPMorgan Chase Essay Example | Topics and Well Written Essays - 1250 words - 1

JPMorgan Chase - Essay Example However, losses also occur due to internal frauds and corruptions which lead to comparatively severe consequences. Due to this banking activities are administered by the security agencies like Security and Exchange Commission (SEC) and Commodities Futures Training Commission (CFTC). The prime responsibility of these security agencies is to look after the financial dealings within the banking sector and to investigate the losses and fraudulent activities. The summer of 2012 brought a very distinctive case forward in the history of financial gambling as a leading bank of United States of America was found to have a loss of $5.8 billion. The company officials reported that the loss occurred due to the poor investment decision made by the management with respect to trading. Later on this statement given to the CFTC inspectors was found to be false and the overall inspection showed some counter results. The bank officials working on trading investment left the bank soon after this event w hich raised a lot of questions to the investigating officers (Farrell, 2012). Role of SEC and CFTC in preventing high risk gambles When a bank or any other financial institution faces a loss due to gambling then the overall economy of the country has to bear its consequences since these two economic sectors act as the most significant structural blocks for any nation. In relation to this the role of SEC and CFTC also becomes substantial as they are the key forces behind the prevention of such activities. Their prime concern is to ensure that maximum protection is extended to the investors, rules are fairly followed by the banks, financial market is operating efficiently and lastly there is enough capital available to the banks and other financial institutions to carry on their activities (Schapiro, 2012). Among these the duty of protecting the investors safeguards high risk gambles. In addition to this, these agencies implement laws regarding the fraudulent activities reported by th e financial institutions. For instance, in the case of JP Morgan Chase the CFTC investigated the overall scenario and found that initial reporting made to the agency was falsified and that the real reasons behind the massive loss were in kept hidden by the Chief Investment Office (CIO). CFTC was responsible to look after trading and financial derivatives while on the other hand SEC supervised the bank’s financial disclosures from the stockholders so as to investigate the details of such a massive loss (Gary Shorter, 2012). Valid Contract Contracts are not just general agreements between two parties rather they are the legally supported documents which can be challenged in the court. The contracts are made to give legal assistance to an agreement so that in future if either of the parties commits an illegal activity then the other one can save itself from potential losses. Due to the legalities attached to contracts there are certain essential elements of a Valid Contract whic h makes it fully acceptable in courts and in legal institutions. Following are the essential elements of a Valid Contract (Elements of a Contract, 2013): Offer and Acceptance: First of all an offer is made by one of the parties which can be accepted or rejected by the second party. If the offer is accepted by the other party then the procedure moves on. The acceptance of the offer reflects the agreement of the other party regarding all the stated rules and regulations. Intention to build successful legal relations: A valid

CompareContrast Nathaniel Hawthorne's heroines in The BirthMark and Essay

CompareContrast Nathaniel Hawthorne's heroines in The BirthMark and Rappaccini's Daughter - Essay Example This has led to a few of them being described as "dark heroines" (Bell, 20); Beatrice Rappaccini, the bewitching daughter of the brilliant, but sinister scientist Rappaccini and to a lesser extent, Georgiana Aylmer, the beautiful young wife of the obsessed scientist Aylmer, are examples of poignant, yet powerful 'dark heroines'. This short essay shall compare and contrast the heroines of two of Hawthorne's short stories, 'The Birth-Mark' and 'Rappaccini's Daughter' respectively. This essay shall cite appropriately from them and other secondary sources to show that, while both the heroines testify to their purity of character by their ultimate sacrifices, Hawthorne's portrayal of Beatrice Rappaccini more than Georgiana Aylmer, aptly suits a 'dark heroine'. Both 'The Birth-Mark' and 'Rappaccini's Daughter' of Hawthorne warn the society regarding the excessive pursuit of science and technology without morality. The stories end as tragedies with the heroines falling victims to the evil obsessions of the dominant men around them. In 'The Birth-Mark' Hawthorne depicts his heroine Georgiana as a powerful image of beauty, that she is praised by her husband Aylmer as one who "came so nearly perfect from the hand of Nature" (The Birth-Mark 1021). She is young and beautiful, but for one "visible mark of earthly imperfection" (The Birth-Mark 1021) on her cheek. ... er husband in particular, and the male world in general perceived as negative - "Masculine observers contented themselves with wishing it away, that the world might possess one living specimen of ideal loveliness without the semblance of a flaw" (The Birth-Mark 1022). Indeed this becomes the focal point of the story itself, and ultimately causes her death. Hawthorne introduces the element of evilness in the form of Aylmer, young Georgiana's science-loving husband; what was trivial matter to him before marriage, appears "more and more intolerable with every moment" to him after marriage, and he is obsessed with removing it, so as to make her perfect. "I am convinced of the perfect practicability of its removal" he retorts to her innermost fears of it being fatal. Here again Hawthorne introduces the element of fantasy in the form of Georgiana's dream, of approaching doom. He scorns, scoffs, chides, coaxes and cajoles her (The Birth-Mark, pp. 1027-8) to have trust in his science, and even tries to hide the fact that it may be "dangerous" (The Birth-Mark, p.1030). Though Hawthorne's heroine is aware that the experiment may not be to her advantage, she is sweet and pure in character, loves her husband so much that she is unable to see him pained over the blemish in her cheek. She would rather give her life than allow it to stand between their happiness, and begs him "Remove it, remove it, whatever be the cost, or we shall both go mad!" (The Birth-Mark 1030) That her love is pure and untainted is explicitly brought out by Hawthorne through her quiet words "There needed no proof; Give me the goblet I joyfully stake all upon your word" (The Birth-Mark, 1031). She remains true in her love for her husband, till her dying moment, though she allows him to realize his folly of

Nursing Education Around the Globe Research Paper

Nursing Education Around the Globe - Research Paper Example ya The major comparison in the government influence of the nursing education between China and Kenya is that; both countries’ initiative to establish nursing training and certification were started by the respective governments, with the Kenyan training and certification program running for 31/2 years, while the Chinese program took 4 years (Xu, Xu & Zhang, 2000). Political control has also characterized the nursing profession and development in both Kenya and China, where the respective governments, through the ministries of health, have been responsible for approving the nursing courses and certification programs in the countries (Klopper & Uys, 2003). The governments have been involved in establishing regulations and laws that governs and controls the nursing profession. Several laws and ordinances have been established by the two governments, to act as the tools through which the nursing profession is politically controlled. In Kenya, the 1946 June Ordinance No. 16 was est ablished to control the health activities of the nurses (Mule, 1986). Similarly, the political control of nursing profession in China can be traced back to 1949, when the education reform in China abolished the post-secondary nursing training, instead introducing the 3-year nursing training, following the 9 years of primary and secondary education (Xu, Xu & Zhang, 2000). Both countries have established Nursing organizations, responsible for uniting, developing, and promoting nursing professionalism, with the Nursing Council of Kenya (NCK) being the peak body of the nursing profession in the country, while the Chinese Nursing Association (CAN), is similarly the peak nursing organization in China (Xu, Xu & Zhang, 2000). Both the organizations are responsible for establishing the nursing syllabus... This paper approves that the Current System of Nursing Education in both China and Kenya occur in various cadres. Both China and Kenya have certification programs for ursing, in form of 3-years comprehensive training, which caters for the preliminary training, ward rotation and theory in clinical training. The comparison in both countries is that; the qualification for nursing certification program is the completion of secondary education. The characteristic of the current systems of nursing education in both countries is that; both countries have established post-basic nursing qualifications, which include diplomas, bachelor of nursing degree, and masters in nursing. The comparison is that the doctorate program in nursing is yet to be fully commissioned in both countries, following the governments’ regulations that have not yet approved the doctorate in nursing. All the post-basic nursing qualifications programs are undertaken in hospital-based training institutions, where the trainees in this profession are full-time based course attendants. this essay makes a conclusion that Nursing Education in both China and Kenya bears universal fundamental characteristics, in terms of government and Nursing organizations control, training and growth, notwithstanding that the nursing profession in both countries is a function of the western missionary arrival into the countries. Additionally, the high standards of qualifications are also eminent requirements in this profession for both countries, while the training period for the nurses and the areas of training are similar.

Bayard as the `Unvanquished of the Novels Title Essay

Bayard as the `Unvanquished of the Novels Title - Essay Example Bayard, growing up in the vanquished South and under the influence of a father whose ethos revolves around war and dreams, could have easily absorbed an ethos of self-destruction and vanquishment. Colonel Sartoris’ legacy, and indeed the family heritage, is one of war; a legacy which defines heroism and honour in terms of the destruction of others. It is a legacy which irrevocably defines war as glory and the defeat of others as heroism. Within the context of this legacy, one inherently founded upon the precept of vanquishing the `other,’ In so doing, he ultimately engages in self-destruction. In addition to the above, Colonel Sartoris emerges as a dreamer - a man whose thoughts are so intently focused on his perceptions of honour and on the maintenance of the previously defined legacy that he fails to connect with the reality around him. In articulating the nature of that dream, Drusilla tells Bayard that his father â€Å"is thinking of this whole country which he is trying to raise by its bootstraps, so that all people in it, not just his kind nor his old regiment, but all people, black and white, the women and the children† may enjoy a better life (Faulkner, p. 256). This is an undoubtedly noble and honourable dream but it is, nonetheless, a dream. The very concept of dreams effectively signifies a rupture with, and destruction of, reality. From this perspective, therefore, Bayard is raised in an atmosphere which should have imposed self-destruction upon him, whether consequent to the ethos embraced within the family legacy or that contained within his father’s dreams.
