one human resource manager recently got a thank you note on her iPhone that said “Thx 4 the Iview! Wud to wrk 4 u!!!” The manager had liked the candidate’s interview, but after getting the note, she put him in the reject pile. Do you think it was fair for the manager to automatically reject the candidate? Should “textspeak” be considered acceptable workplace communication? Discuss. Solution as per the above explanation we can not say that what the manager has did and because of the text mail only he rejected the candidate. and some times it may not possible to select the candidate even he did best in the interview. there would some one else who performed best than the other. in those times, he may reject the good one to choose the best. and based on the above explanation it can be observed that the interviwer is a lady and the interviewee is a gent or boy. she may not like expressing his ability and interest to work in the firm. and she have not decided and discolsed it to the guy that he is selected or rejected. she may put it hold and mean while by looking at his message she may refused the application. but, because of the only message if she rejected him, it is not fair..

arorasales234

Mutations rII1 and rII2 are known to fall into the rIIA and rIIB cistrons (genes) respectively. Mutations rII1 and rII2 are used to infect E. coli B at very low multiplicity of infection (m.o.i.) and the progeny phage collected. These phage are then used to infect strain K at very low m.o.i.. The resulting phage are diluted and plated on both E. coli B and E. coli K. Do you expect more plaques on strain B, on Strain K, an equal amount on both or is it impossible to tell? Explain Solution Strain B have more plaques because it supports the growth of all viruses,wild type T4 as well as rII mutants which are able to complete their lifecycle in this strain thus giving total number of viruses developed. Strain K have low number of plaques because in this strain only wild type T4viruses can grow and complete their lifecycle..

Money laundering has become a mechanism for financing terrorist acti.pdf

Money laundering has become a mechanism for financing terrorist activities. Describe how and why terrorist organizations use money laundering a tool for financing their activities. How can investigators detect and investigate these schemes? What specific types of evidence will be useful to investigate these crimes? Identify a real case of money laundering as an example in your answer Solution Money laundering is process by which the criminals use the financial system to make illigetimate money appear legitimate through a web of complex transactions. Process of money laundering: (i) Placement Stage : This is the initial stage in money laundering where in criminals move physical cash in to the banking channel. (ii) Layering stage : In this stage , the money deposited in the banks is routed through complex financial transactions where the link to the origin of the funds is broken. (iiI) Integration Stage : The illicit funds are now pushed in to the economy and financial system by providing legitimate explanation for illegitimate funds. Terrorist agencies use money laundering tools to finance their activities since in such a prcess it is very difficult to establish the link to the illegally gotten money and trace it back to the crime. Investigators can detect such schemes if they find any inconsistent business activites of companies or individuals outside their routine activities. Such activities can include unusual high cash transactions, dealing in multiple currencies, transactions which do not meet the business\' core activities. Some of the ways in which investigators can investigate the schemes are as below : (i) The first step is to identify the business or individual profile of the criminal who has engaged in such an activity. (ii) If a business group or an organisation is involved then the next step is to identify the key personnel who run the group since they will be directly involved in this. (iii) The third step is identify the money flow patterns of the company and the location of the bank accounts of the organisation. (iv) Obtaining the financial records and the books of the company and corroborating the same with externally obtained bank statements. One of the world\'s most famous terrorist organisation Al Qaieda has been involved in multiple terrorist crimes that has killed millions till date uses money laundering techniques to finance their activities. The organisation had multiple financial interests through banks, holding companies, foundations,properties and charities in Britain , France and many other European countries. The organisation mainly took the help of BCCI in Britain in the 1980s before the bank was closed down by Bank of England..

Independent auditors must provide dual opinions. What are these two opinions and what is the difference in them? Solution Dual opinion is the opinion on the effectiveness and effective working of internal controls adopted by the firm to avoid accounting manipulations . Firm adopt internal controls to present financial statements at very best fair and transparent manner. So to avoid any deceit and manipulation activities to hide any or miss any issue , internal controls are adopted . Auditors also check the effectiveness of these controls and provide their opinion at the time of auditing the financial statements.

Imperialism and Nationalism are often incongruous concepts that exis.pdf

arorasales234

Imperialism and Nationalism are often incongruous concepts that exist simultaneously in a given context. During the period after WWI, nationalism was used to create new states in Europe and the Middle East. Although these nations were recognized as independent, self-governing states, they were either directly or indirectly connected to previously existing states. Discuss the ways which Nationalism influenced the formation of new states. In your discussion, speak to the role of imperialism to uphold, hinder or complicate the formation or survival of these states. Is it possible to separate imperialistic goals from nation building? Support your argument with evidence. Solution The First World War saw the colonial empires of France and Britain mobilised to aid European and imperial war efforts. This mobilisation and the difficulties of demobilisation placed considerable strain on imperial systems which were only partly addressed through post-war reforms. The Great War also unleashed an unprecedented ideological challenge to colonial rule embodied in the ideas of Woodrow Wilson which took form through the mandatory system. Although there were some restrictions placed on the activities of the colonial powers, both Britain and France maintained their imperial rule, often violently suppressing anti-colonial nationalist challenges. From a colonial perspective the First World War did not end cleanly. Major combat operations on the Western Front may have ceased on 11 November 1918, but a raft of smaller conflicts, some of which had emerged out of the upheavals of 1914-1918 and others which were only tangentially related to the Great War, lingered on into the immediate post-war years. For example, it was not until spring 1919 that, rather belatedly, German efforts launched at the start of the war to stoke an Afghan challenge to the British Raj actually bore fruit. The Third Anglo- Afghan War was more than just a continuation of the seemingly interminable struggle between British imperial and Afghan forces along India’s north-western frontier. It was, in part, the continuation of Germany’s Weltkrieg, an attempt to globalise the European struggle of 1914- 1918 in order to distract the Entente powers from the main theatre of operations.[1] Unfortunately for Wilhelm II, German Emperor (1859-1941), the German army was defeated on the Western Front before this globalisation of the war could achieve its aim of forcing the British to choose between a European victory and their empire. The Third Anglo-Afghan War was not an isolated event in the wake of the First World War. Indeed, the decade following 1918 saw a major inter-state conflict being replaced by myriad smaller ones, often within collapsing states and imperial polities. This was a point not lost on contemporaries. In particular it was noted by, and arguably defined the thinking of, the arch- pessimist of Britain’s post-war situation, General Sir Henry Wilson (1864-1922), the British army’s Chief of the.

arorasales234

Explain why it can be problematic to base morality and ethics only on religion. Solution The existence of ethics as a science, moral as a positive framework out of religion is as old as civilization. Aristoteles and Platon stated that gods did not need of men, so religious moral is unuseful. But, other authors as C.S. Lewis recognize that is possible moral behavior without be a religious practice, however, the criterion of categorization between good or bad is not sustainable, because it would be a preference choice, without transcendence. Philosophers as Nietzsche, Kant or Holyoake agree about religion operates as an exogenous imposition of behaviors, that they do not have any ethic value, because they are not self- motivated, instead, non religious ethic is more valuable in this sense. There is a general accepted principle about the religious freedom and the laicity of the State, because religions has different emphasis and moral codes among the world, and the imposition of demand ethical behaviors have been addressed to an specific religion is a violation of the rights of the non followers of this faith. However, society requires an objective system of convivence which respects everybody believes, since there the need of a rational way of ranking moral decisions. Other aspect is that it has been argued that many religious moral codes do not promote the self superation, just they keep you saved of to be a criminal..

Describe what is happening in Italy (or you may substitute Argentina or Iran) and how that might impact things like exchange rates, inflation and/or interest rates. Solution Let we take example of Iran, As we all know that USA has put a number of sanctions on Iran due to which trade with Iran is difficult, Country like India which Import a major portion of its crue oil import from Iran, now after these sanctions, India could not buy crude oil from Iran and this will also happen with other countries too. So this types of sanctions will force Countries like India to look for another partner for Oil import and this will have impact on its currency exchange rates as other oil exporting countries may demand different price for the crude oil. on other hand after so many sanctions Supply of curde oil will increase and prices may also increases which will result in more pressure on countries and this will have impact on exchange rate and when prices of crude oil will increase it will impact economy and inflation will also increase and general price level will also increase..

Consider an extension of the queue abstract data type, called a .pdf

arorasales234

Consider an extension of the queue abstract data type, called a minqueue, which supports operations ENQUEUE, DEQUEUE, and FINDMIN. Assume that the elements to be stored are integers (or any other totally ordered data type). FINDMIN simply returns the smallest element in the minqueue, but does not remove it. Using a standard implementation of a queue, the FINDMIN operation takes O(n) time in the worst case. However, consider a more clever data structure for this abstract data type which works as follows: There are two regular queues used. The first queue is called the ”real queue” and the second queue is called the ”helper queue”. When the ENQUEUE(x) operation is performed, the element x is enqueued in the regular way on the real queue. The element x is also enqueued at the end of the helper queue. However, if the element y immediately ”in front” of x on the helper queue is larger than x, then y is removed from the helper queue. This process of x annihilating the element immediately in front of it is repeated until the element immediately in front of x is less than or equal to it or x is at the front of the helper queue. Describe how the DEQUEUE and FINDMIN operation are implemented in this data structure. Give the worst case running time for each of ENQUEUE, DEQUEUE, and FINDMIN using this data structure. Give an argument using the potential method to show that any sequence of n ENQUEUE, DEQUEUE, and FINDMIN operations requires only O(n) time.

Case study on Queensland Health Payroll Debacle & Queensland Government Bans IBM from IT contracts. Questions: 7. What could IBM have done to prevent the release of its defective payroll system? Solution The queensIsland had banned IBM for further contracts, following report about payroll system it was blamed towards vendorers. In 2010, government started introduction of IBM based Payroll system which makes million bollers over budget and indulge payments to thousands of people.projects initiall expectations is 6.19 million dollars but current estimation cost about 1.2 billion dollars. Early the qeens government has launced enquiry. the report that resluts out from enqury had given in the week.the report gaves a critcal of all members including IBM.The problms which makes project comes dowm, in major failure is by multiple peoape to loose up their responsibility properly,” Richard who led enquery had said that.. then IBM is not allowed to any of the contracts with the state .which was said by Queeens Government. But IBM bought an application to claim up the damage, argue that in agrment signed in 2010 the Government has waved its rights to sue. This afternoon supreme court judge ruled IBM favour.it means that state government cannot go for current damage some defect are found in payroll system when it is launced in 2010 which produce a result that many of the employees in the queen state had remaind withe unpaid and underpaid..

Records of the missions of Baja California in the form of baptisms and burial records provide an ideal opportunity to examine the consequences of what is known as the \"Colombian Exchange,\" the movement of organisms large and small between the Old and New Worlds after the appearance of Columbus in 1492. The data below are two time series of the numbers of baptisms at two Central Baja missions, San Jose de Comondu and San Gertrudis. The data are for the decade 1770 - 1779. (a) How would you generally describe the trend of baptisms for the two missions over this period? Do the missions appear to show similar trends? Justify your response by appealing to the graph. (b) One of the influences of the meeting of the Old and New Worlds was the transmission of diseases to the native populations, who had developed no natural immunity from European diseases. If there were anecdotal evidence for an outbreak of disease during this time, which mission and what year seems to be the most likely candidate? Again, justify your response by appealing to the graph. (a) How would you generally describe the trend of baptisms for the two missions over this period?

Which phyla have phloem sieve elements? Bryophyta Monilophyta Coniferophyta Anthophyta Which phyla have roots? Bryophyta Monilophyta Coniferophyta Anthophyta Which phyla have stems? Bryophyta Monilophyta Coniferophyta Anthophyta Which phyla have stomata and guard cells? Bryophyta Monilophyta Coniferophyta Anthophyta Solution Please find the answers below: Part 32: Choice 4 (Anthophyta, or modern day plants or angiosperms are the most advanced nature of plants which contain complex vascular tissues. They have separate conducting tissues for water and food. Their sieve tubes contain companion cells and other accessory cells as well.) Part 33: Choice 4 (As described above, anthophytes represent the modern day flowering plants or angiosperms. They contain a true stem which gets lignified with time and becomes hard. Although weak and tender stems are also visible and present in ferns and other lower plants, a true hard lignified stem is found in conifers and angiosperms only) Part 34: Choice 4 (The lower plants like bryophytes, pteridophytes etc do not contain true vascular tissues. They are also devoid of any stomatal openings and guard cells. True stomata and guard cells appeared in the flowering plants with diverse functions. Though some conifers also contain stomata but generally, their stomatal openings are minimized to prevent evaporation of water.).

Where do hydrogen bonds occur in the DNA structure and how does hydr.pdf

arorasales234

Where do hydrogen bonds occur in the DNA structure and how does hydrogen bonding contribute to the secondary structure of DNA? Solution Ans). The two strands of DNA stay together by hydrogen bonds that is complementary nucleotide base pairs. Two hydrogen bonds occur between the adenosine and the thymine base pairs, and three hydrogen bonds occur between the cytosine and the guanine. Secondary structure is the set of interactions between bases. In DNA the two strands of DNA are held together by hydrogen bonds..

What is the concept of spoiled identity as it relates to disability.pdf

What is the concept of spoiled identity as it relates to disability? Do you believe that some of all aspects of spoiled identify are inevitable? Solution While interacting with someone we tried to present ourselves to the other participants stigma is an attribute that is discrediting do whatever we are trying to portray to others a particular identity is set to be spoiled by having a stigma associated with it Goffman points of that stigma will have great effect on the human beings. Anyone who is disqualified from social acceptance is stigmatized. Stigma includez physical deformities blemishes or tribal stigma like race and religion. The stigmatized people are rejected and their face discrimination in the society. All these things show the effect on self esteem academic achievement, performance et. Stigmatization is a process in which the minorities are the inferior portions disqualified by the powerful are superior people the stigmatized people become socially excluded based on their characteristics that led to the stigma. . Due to disabilities or external deformities like leprosy Muscular dystrophy cleft lip are considered as what type of stigma gosselin emphasized how stigmatized people manage their child identity before the normal people he also focused on stigma not as fixed or inherent attribute of a person but described it as an experience. In a research it was found that obese and overweight women feel uncomfortable and I\'m not very social which makes other people which come into contact with them become an interesting and it was found that the overweight women developed lower self esteem. Sometimes it is inevitable but research is going on to rule out this..

111. Twenty-one executives in a large corporation were randomly selected to study the effect of several factors on annual salary (expressed in $000s). The factors selected were age, seniority, years of college, number of company divisions they had been exposed to, and the level of their responsibility. The results of the regression analysis follow. Write out the multiple regression equation. Solution The multiple regression equation is: Annual salary=-0.031 age+0.381 seniority+ 1.452 years of college -0.089 divisions +3.554 level.

What causes concrete to be hard (change from a fluid state into a ha.pdf

arorasales234

What causes concrete to be hard (change from a fluid state into a hardened state)? Solution Concrete is prepared by mixing cement, water, and aggregate together to make a workable paste. It is molded or placed as desired, consolidated, and then left to harden. Concrete does not need to dry out in order to harden as commonly thought. The concrete (or specifically, the cement in it) needs moisture to hydrate and cure (harden). When concrete dries, it actually stops getting stronger. Concrete with too little water may be dry but is not fully reacted. The properties of such a concrete would be less than that of a wet concrete. The reaction of water with the cement in concrete is extremely important to its properties and reactions may continue for many years. When water is added to cement, each of the compounds undergoes hydration and contributes to the final concrete product. Only the calcium silicates contribute to strength. Tricalcium silicate is responsible for most of the early strength (first 7 days). Dicalcium silicate, which reacts more slowly, contributes only to the strength at later times..

What are parametric and nonparametric inferential testsName and d.pdf

arorasales234

What are parametric and nonparametric inferential tests? Name and define the two types of chi-square tests. Solution There are two types of test data and consequently different types of analysis. Parametric data has an underlying normal distribution which allows for more conclusions to be drawn as the shape can be mathematically described. Anything else is non-parametric. Parametric methods are those for which we know that the population is approximately normal, or we can approximate using a normal distribution after we invoke the central limit theorem. Non Parametric methods are statistical techniques for which we do not have to make any assumption of normality for the population we are studying. Chi-squared test of independence, Chi-squared Goodness of fit.

Two terrestrial ecosystems based on photosynthesis and and chemolith.pdf

arorasales234

Two terrestrial ecosystems based on photosynthesis and and chemolithosynthesis (hydrothermal vents) trap their energy from specific energy sources. Tidal squeezing has also been suggested. The type of energy sources define the character of the ecosystems observed. What other energy source can you identify that might drive other kinds of ecosystems elsewhere in the universe? Speculate on the type of organisms that might evolve based on that energy source. What would be the characteristics of the primary producers (the organisms that trap the energy)? How can the energy be transferred to the rest of the food chain? What would a planet, where such organisms evolved, be like? DO NOT use energy sources listed above. Use an energy source that is plausible within the laws of physics. Just looking for a few main ideas that I can dive into to finish this promt.. Solution i) Cosmic ray is other kind of energy source that might drive other kinds of ecosystems elsewhere in the universe. ii) The organism might evolve iii) Characteristics of primary producer: iv) The components present in the cosmic ray are absorbed by primary producer. Primary consumer by eating the primary producer absorbed their organic substances and metabolizes them. Secondary consumer behaves quite similarly eating the previous organism. In this way this process goes on from one category organism to another. The transfer of energy through the food chain determines some heat to be lost into the environment according to the thermodynamics which indicates that secondary consumer will have less energy than primary consumer and primary consumer have less energy than producer. This transfer of energy from one trophic level to next is called efficiency of food chain. v) In this scenario.

Operation Blue Star - Saka Neela Tara

Balvir Singh

Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup. The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
