Marketing journal - Essay Example Normally surveys are conducted demographically to determine various segments of buyers according to age, sex, education, location and other factors. However this kind of division fails to highlight the motivation of the consumer and often marketing based on such results is disappointing. A good method of measuring this has been devised by SRIC-BI who has conducted psychological survey of thousands of consumers from every walk of life during 1987-92. They call it VALS. This survey attempts to analyze the inherent instincts or psychological traits of the consumer that have developed over his/her experiences and knowledge and have become the drivers of purchase decisions. This has provided an insight about why we buy. I undertook this seemingly incongruous survey that seemed simple and somewhat inconsequential. However the results highlighted my attitude and aptitude and I must admit that it was able to capture the essence of my personality. The survey categorized me into the segment called Thinkers. Under VALS terminology the three segmentations of consumers are determined by their motivation. These are Innovators, Thinkers and Survivors. The descriptions are indicative of their capabilities; the innovators are daring and will be easily induced to trying new products and experimenting with the unknown; the thinkers are conservatives but willing to try new products within the existing parameters of their attitudes and aptitudes; while the survivors are those who are practical and will make decisions only according to their means. Recently I decided to buy a laptop for use in my consulting profession. My requirements were that the product had to be easily portable, that would not fail at a critical moment, should be reasonably priced and, since it was a high-tech gadget, good and prompt after sales service should be available whenever and wherever needed.

Google Essay Example | Topics and Well Written Essays - 500 words - 2

Google - Essay Example For example, in the third quarter of 2007 alone, Google hired 2130 people to ensure that it had the best brains and the smartest people on board its corporate engine.(Dignan, 2007). As Dignan (2007) has pointed out, employment at Google is largely centred around work on the search engine and ad words; as a result a slow down in business, such as the current recessionary period, could affect the Company adversely. But the Company’s recruitment and HRM policies have been strongly focused on pulling in the best and smartest people into the organization, because of its recognition that innovation is the driving factor ensuring success in the IT business today. One of the reasons for Google’s spiraling success is its thrust on innovation and the belief that good ideas can, and should, come from anywhere.(Business Week, 2005). Engineers in the company are allowed a day off in a week to work on their pet projects and there is a high level of receptivity from the upper echelons of management to new and innovative ideas. By constantly staying on the cutting edge of innovation, the company has been able to sustain itself as the market leader through the development of new products and services. There is no strict hierarchical structure in place at Google and the corporate environment is characterized by informal networking, such that the CEO Eric Schmidt himself, is approachable to every employee, who is at liberty to pitch a new sales or networking/IT idea to him anytime. Google’s HRM policy is different from other organizations, characterized by the high level of informality and networking, which is a very successful business policy insofar as Google is concerned. Since the products and services in the IT business can be easily replicated by competitors who can put out their version of a product or service, the cutting edge in this business lies in the development of innovative new

Limitations and Requirements of ANOVA Essay Example | Topics and Well Written Essays - 500 words

Limitations and Requirements of ANOVA - Essay Example The samples’ variances should not be different though some departures can be accommodated. All individuals used in the samples must be selected randomly from the population. All individuals of the samples must have equal probability for being selected. The sizes of the sample should be equal but there is an allowance of some differences. One of the limitations of ANOVA is that, when a significant data difference cannot be found, the samples cannot be said to be the same. It only indicates differences between groups and not groups which are different. Normality assumes that the errors which are random within each group of treatment, the groups’ mean deviations, have a normal probability distribution. For normal data but variances which are heterogeneous, ANOVA is good for balanced designs but not for designs which are highly unbalanced. In normal data setting, heterogeneous variances and designs which are unbalanced, Welch’s ANOVA might be used for the accommodation of unequal variances. With variances which are homogenous but data which is non-normal, ANOVA is good for designs which are balanced with large samples. It is not good for unbalanced designs with small samples. In non-normal data setting, variances which are homogenous and a small sample or unbalanced design, a non-parametric procedure is preferred. If the distribution of data is not normal and heterogeneity of variances exist, there might be transformation necessity. The importance of a design which is balanced and existence of a large sample must be pu t into consideration. A common standard deviation is shared by all normal distributions. The different t-test options can be used around the equal variances assumptions or unequal variances assumption. The f-test, apart from being used to for t-tests, it can also be used to compare variations in two data sets in the CJ data. The test makes use of a calculated F stat

A review of Bioactivation and Tissue Toxicity

A review of Bioactivation and Tissue Toxicity Kong Wei En (BP0711031415) Raymond Koh Chee How (BP0711031287) Jennie Lee Sheah Lin (BP0711031372) Prashanthini A/P Janardanan (BP0711031156) Hong Wei Siong (BP0711031194) Shalini A/P Shanmugavelu (BP0711031145) Introduction Xenobiotics are foreign chemicals in the body [1]. The human body has adapted processes collectively termed as biotransformation to excrete these xenobiotics [1,2]. Biotransformation generally occurs sequentially in two phases [1,2]. Phase I reactions add new functional groups to the parent compound while phase II reactions conjugate these new functional groups with polar groups [1,2]. The end-result of biotransformation is decreased lipid solubility, thus increasing renal excretion [1,2]. The liver is the chief site for biotransformation, [1,2]. Enzymes such as cytochrome P450 and peroxidase enzymes are responsible for biotransformation [3,4]. Occasionally, bioactivation occurs, in which the inert parent compound is modified into toxic metabolites [1,3,4]. The toxic metabolites are either electrophiles or free radicals, which interact with body tissues, subsequently causing toxicity [3,5]. Electrophiles Electrophiles are species deficient in electron pair generated through Phase 1 metabolism by CYP450 [5]. They are short-lived (with the possible exception of some acyl glucuronides) and not usually detectable in circulation [5]. Electrophiles can be generated from carbon, nitrogen or sulphur containing compounds [4]. The most frequently metabolised structural alerts are aromatic systems with electron-donating substituents and some five-membered heterocyclic [6]. Electrophiles cause toxicity through the formation of irreversible covalent bond to nucleophilic tissue components which includes macromolecules (proteins, nucleic acids and lipids) or low molecular weight cellular constituents [4]. Covalent binding generates potent and long lasting toxic effects because the covalently modified enzyme/receptor is permanently inactivated [4]. The covalent binding to DNA leads to mutation, tissue necrosis, carcinogenicity and tumour formation [4]. Mutations arise when the electrophiles escape the repair mechanisms of the cell, may be fixed and passed to the progeny [4]. If the electrophiles bind to protein, they will disturb the physiological homeostasis, leading to cell death [7]. Examples of electrophiles include epoxide, hydroxylamines and aldehydes [4,5]. Free radicals Free radicals (species containing an odd number of electrons) may be cations, anions or neutral radicals [8]. Free radicals are generally formed via NADPH CYP450 reductase or other flavin containing reductases [8]. They provide toxicity by peroxidation of cellular components. An important class of free radicals is organic free radicals such as hydrogen peroxide and superoxide anion [8]. The potential toxicity of free radicals is far greater than electrophiles [8]. Free radicals are able to produce chemical modifications and damage to proteins, lipids, carbohydrates and nucleotides [9]. If the reactive free radical is formed close to DNA then it may produce a change in the structure resulting in a mutation or cytotoxicity [9]. Protein and non-protein thiol groups are readily oxidized by many free radicals and may lead to profound changes in enzyme activity [9]. Another major pathway of metabolic disturbances is depending on covalent binding with cell components such as protein, lipid and nucleic acid to from a stable covalently bound adduct that may grossly distort structure and function [9]. Reactive free radical may also damage cells through membrane damage [9]. Examples of free radicals include hydrogen peroxide, hydroxyl radical and peroxynitrite [10]. Examples of drugs undergoing bioactivation and causing subsequent tissue toxicity Table 1: Several drugs, with their corresponding toxic metabolic pathways and the subsequent adverse effects. Drug Metabolic pathway Adverse effects Chloramphenicol Chloramphenicol is first oxidised by CYP monooxygenase into its dichloromethyl moiety [11]. Hydrochloric acid is then eliminated to produce a reactive metabolite that interacts with the Æ -amino acid of a lysine residue in CYP monooxygenase [11]. The enzymatic reaction is eventually retards over time, leading to adverse effects [11]. Apalstic anemia [12] Bone marrow toxicity [12] Acetaminophen The reactive metabolite is called N-acetyl-p-benzoquinone imine (NAPQI) [11]. Metabolic pathway 1: Acetaminophen undergoes N-oxidation to become N-hydroxyacetaminophen, which then undergoes dehydration to form NAPQI [11]. This pathway is probably uncommon as N-hydroxyacetaminophen is not a chief intermediate in the oxidation of acetaminophen [11]. Metabolic pathway 2: NAPQI undergoes a Michael-type addition with either glutathione or protein thiol groups [11]. Hepatotoxicity [11,12]. Tienilic acid Tienilic acid is oxidised by CYP2C9 to either thiophene sulfoxide or thiophene epoxide [11]. These electrophilic reactive intermediates alkylate CYP2C9, permanently binding themselves to the enzyme [11]. The enzyme is subsequently inactivated [11]. The body then produces anti-LKM2 autoantibodies against the native CYP2C9 enzyme and the modified CYP2C9 enzyme [11]. Immunoallergic hepatitis [11] Halothane Matabolic pathway 1: In hypoxic states, halothane undergoes reduction to produce the 1-chloro-2,2,2-trifluoroethyl free radical [11]. This free radical performs a radical attack, leading to the necrosis of hepatocytes [11]. The radical may also react with the Fe2+ in the CYP enzyme to form an iron ÏÆ'-alkyl complex [11]. This complex then causes the necrosis of the hepatocytes [11]. Metabolic pathway 2: Halothane undergoes oxidation to produce trifluoroacetyl chloride [11]. Liver proteins are then trifluoroacetylated on their Æ -NH2-lysyl residue [11]. This newly formed neoantigen evokes an immune response towards the liver [11]. Severe hepatitis [11] Valproic acid Valproic acid is metabolised by CYP2C9 into 2-propyl-4-pentenoic acid, also termed as Δ4VPA [11]. This metabolite can then undergo two pathways [11]. Metabolic pathway 1: CYP enzymes metabolize Δ4VPA into a reactive metabolite, which then proceeds to alkylate the prosthetic heme of the CYP enzymes [11]. Hence, the enzymes are inhibited [11]. Metabolic pathway 2: The Δ4VPA metabolite undergoes ÃŽ ²-oxidation to generate the Coenzyme A ester of 3-oxo-2-propyl-4-pentenoic acid [11]. This new metabolite alkylates the terminal enzyme of ÃŽ ²-oxidation (3-ketoacyl-CoA thiolase) by a nucleophilic attack at the olefinic terminus [11]. Hepatotoxicity [11] Troglitazone Metabolic pathway 1: The thiazolidinedione ring undergoes oxidative cleavage to produce a reactive sulfoxide intermediate, which spontaneously opens its ring [11]. Metabolic pathway 2: The phenolic hydroxyl group of troglitazone undergoes a one-electron oxidation catalysed by CYP3A to produce an unstable hemiacetal, which spontaneously opens to form a quinine metabolite [11]. The quinine metabolite then undergoes the metabolic pathway described earlier (metabolic pathway 1) [11]. Metabolic pathway 3: The unstable hemiacetal produced in metabolic pathway 2 may undego hydrogen abstraction, resulting in the production of an o-quinone methide derivative [11]. Hepatic failure Death (due to hepatic failure) [11]. Part 2: Applications of Bioactivation and Tissue Toxicity in Abacavir and Lidocaine Abacavir Abacavir (ABC) is an anti-HIV drug classified as a nucleoside/nucleotide reverse transcriptase inhibitor (NRTI) [13]. ABC possesses a significant role in the treatment of HIV patients [13]. First, ABC is subjected to phase I oxidation to produce ABC-carboxylate, followed by phase II glucuronidation to generate the inactive glucuronide metabolite [13]. Both the glucuronide and carboxylate metabolites are chiefly eliminated in the urine [13]. ABC undergoes bioactivation to form reactive aldehyde metabolites [13]. ABC metabolism to ABC-carboxylate involves a two-step oxidation via an aldehyde intermediate (unconjugated ABC-aldehyde) which rapidly tautomerizes to the more stable conjugated ABC-aldehyde [13]. This reactive metabolite is capable of reacting with proteins to produce covalent adducts, which results in the occurrence of adverse effects [13]. The most prevalent acute ABC-induced adverse effects are the potentially life-threatening hypersensitivity reactions (HSR) that occur within the first 6 weeks of treatment [13]. ABC also possesses the potential to induce cardiotoxicity, which raised further concerns about the prolonged administration of this drug [13]. Lidocaine Lidocaine has been extensively used in the treatment of ventricular arrhythmias [14]. It is also usually administered intravenously to treat and prevent cardiac arrhythmias after acute myocardial infarction [14]. Its chemical structure is an amide with an aromatic group [15]. Lidocaine is chiefly metabolized by the microsomal enzyme system in the liver [15]. The major biotransformation pathways are oxidation and hydroxylation [14]. Lidocaine undergoes oxidative N-deethylation to form the toxic mono-ethylglycinexylidide, which is then hydrolysed to 2,6-xylidine [14,15]. Finally, 2,6-xylidine is modified to 4-hydroxy-2,6-xylidine, which is excreted in urine [14]. Lidocaine also undergoes hydroxylation of the aromatic nitrogen to form N-hydroxylidocaine and the toxic N-hydroxymonoethylglycinexylidide [14]. The active and toxic metabolites known as mono-ethylglycinexylidide and N-hydroxymonoethylglycinexylidide primarily cause neural and cardiac toxicity [14,15]. Early signs of CNS intoxication include shivering, muscular twitching and tremors of the facial muscles [15]. As toxicity is low, it is safely and extensively used to treat arrhythmias [15]. Conclusion To eliminate xenobiotics from our body, processes collectively termed as biotransformation occurs in two phases. However, toxic metabolites (electrophiles or free radicals) may be produced in processes called bioactivation, which interact with body tissues and cause tissue toxicity. The bioactivation and subsequent adverse effects of abacavir and lidocaine has been discussed in detail. References [1] Rang H, Dale M, Ritter J. Rang Dales pharmacology. 7th Edition.

Thomas Becket :: Biography Biographies Essays

Thomas Becket    Thomas Becket during his life was a man of both honor and dishonor.   His decisions, principles, and character made certain aspects of his life honorable, and others dishonorable.   However, it is also extremely important to realize who Becket was honoring.   The three most relevant people he would honor during his life was himself, King Henry II, and God.      Ã‚  Ã‚   Many times during his life, Becket acted without honor.   For instance, when King Henry separated the church and state by making his power superior to the church's, Becket became his right-hand by becoming the Chancellor of England.   While Henry's moves were political and economic, Becket decision to join the king was based purely on allegiance and fidelity to the king.   Becket did not consider the consequences of what a split would do nor did he question and challenge the sanctimonious motives of the king.   Becket also showed a great dishonor to both God and the king when he wore both the Chancellor and Archbishop ring.   He could not possibly honor both, since the King's agenda did not coalesce with the will of God.   Thus he had a false honor to both.   Eventually, Becket made a choice to serve the honor of God above the king.      Ã‚  Ã‚   Becket was also a man of great honor.   He showed reverence to his king by being loyal and keeping his word when he had to give up the woman he loved to the king.   At this moment, he also honored himself by showing integrity and principle over emotional values.   While chancellor, he served faithfully by understanding his duty to the king and code of honor.   The one thing that proved Becket to be a man of true honor was when he humbled himself before the cross and God and vowed his loyalty to the one and only true leader.   After this point, Becket no longer acts to serve the king's honor, but God's because he realizes it is more righteous and rewarding.   Through this decision he chose how he would live for the remainder of his life.   He accepted his obligations as Archbishop of Canterbury and understood how he would inevitably be forced to oppose the king.   He sacrificed his own life by defending the kingdom of God and boldly chose to pursue God's w ill.   This occurs when he repudiates the king's order to renege on his excommunication decision.
