Question: Discuss about the Undergraduate and Postgraduate Students. Answer: Introduction: The cross sectional research design is a kind of observational studies which tends to analyze the gathered data from a specific population or a representation of that population at any particular point of time. In economics, the cross sectional studies generally include the cross sectional regression for sorting out the existence of the independent variables at a specific point of time. This value can differ from time to time due to the time series analysis where the single or multiple economic aggregates can be traced during the course of time. The longitudinal studies are the kind of research design that includes frequent observations on the similar variables, mostly people, over an extended period of time, generally few decades. This study can also be considered as the observational study even though it can be structured as longitudinal experiments (Bryman and Bell 2015). This study is mostly utilized in psychology and sociology. Unlike the cross sectional studies this research de sign tends to track the same people for a long time. On the other hand, comparative research design focuses more for making comparisons across different cultures or regions. However there is a major issue with this design as it may use different categories, so the comparison can be unusual. The Management Consultancy performance is the cross sectional study as it gathers data from a specific population for analyzing. The author has considered three kinds of research designs as longitudinal research deign, such as, repeated cross sectional studies, retrospective studies ad prospective studies. Advantages of the longitudinal studies This study is effective to determine the variables over the course of time as they mostly include the usage of the gathered data for a longer period of time. Therefore it is easier to define the patterns in a more efficient way (Eriksson and Kovalainen 2015). As the longitudinal studies observe a specific set of situations, it makes sure a definite validity and focus of the data. This study is very much effectual for researching on specific developmental trends. Longitudinal studies are mostly flexible as they provide a lot of time for gathering data, therefore allows adequate flexibility (Sekaran and Bougie 2016). This research design also provides higher accuracy while observing the changes gradually. Limitations: Longitudinal studies take a lot of time for collecting all the required data. This study also does not consider the data which are not 100% accurate. Therefore the data collection procedure also takes a lot of time. This study also has the risks of panel attrition which refers to the fact that the researchers have to rely upon the similar subject group for the entire research procedure (Eriksson and Kovalainen 2015). . This study also requires a larger sample size. Longitudinal studies are more expensive than the other research studies. I had participated in a study which had been undertaken in disguise of selling me few cosmetic products. A lady came to my home and asked me to check few cosmetic products from a comparatively new company. I had never heard of the company but I liked some of its products so I bought a few. Later when I came to know that this was a survey, I felt a little bad as this was not conveyed to me at first. I thought it was entirely push marketing and it was a clear case of conflict of interest between the consumers and the suppliers of the products. I think the ethical principle of interest has been breached here. The conflict of interest refers to the situation where an organization or an individual is involved with more than on interest and one of these interests can corrupt the final decision making of any organization or individual (Collis and Hussey 2013). Here the person, who was interacting with me, has been instructed to act like that for their purpose of market analysis. However, at the same time this is working as a violation of privacy for me. Therefore I would not want this to happen to me again. Reliability is a major factor in qualitative research, as it refers to the right replica of the entire research process and its results. However, within the paradigm of qualitative research, the reliability factor is challenged several times because it is entirely dependent on the data. In the qualitative research, data is taken from actual sources; therefore its accuracy should be checked several times (Hair 2015). Furthermore, if there is any kind of vexatious opinion, it can create hindrance for the outcome of the qualitative research. The employees are mostly interviewed about the director of the company. There can be several employees from different levels, who can be interviewed about this matter. However, in this research the employees may provide wrong or biased information. They may think about their job securities while providing information to the researcher. Wilson 2014) shows that there are several instances that indicate that the employees tend to provide biased information as they may think that their information can be leaked and they could be exposed if they are saying things against the director. In such situation, the researcher should give full assurance to the employees that their data will not be leaked and there could be legal issues if that ever happens. The researcher could also sign in a legal paper prior to the interview. It has been found out that if an individual is working long hours, it may damage their personal health, put the safety at risk while in increases the stress. Therefore the employees should not be working very long hours as it can further affect their physical and mental health a lot. The more employees are going to work, the less time they spend for any other activity such as leisure (Bryman 2015). However, this is very important for the individuals to spend quality times with their loved one. Therefore if the individual is not having adequate time for their personal life, their professional life can be jeopardized as well. This process can be done with the qualitative approach. In any organization, the researcher can conduct interviews with the selected employees from different levels. Through interview, the researcher will be able to find out about the work life balance in the employees life. The sampling error is the divergence of the selected sample regarding the traits, characteristics, qualities and behaviors of the entire population. This error occurs for many reasons, such as the researcher can draw various subjects from the selected population, but the subjects may have personal difference. It should be noted that the sample size or the selected sample is just a subset; therefore there is a fine line between the population and sample (Myers 2013). Therefore error can occur. However, the findings can be trusted as it reflects the result of a definite subset of the entire population. Therefore I would have a management decision relying of the findings, as it shows the attitude of the entire population. I may increase the numbers of questions and the sample size so that it would be easier to understand the selected subset. While interviewing or observing a focus group, if the researcher finds out multiple members of the group are answering the same to a specific or a single question, it can be considered as an impact of the groupthink. Groupthink is generally a psychological phenomenon that is triggered as the members of the same group want to minimize their internal conflicts and reach to a compromising decision without any kind of evaluation of the other viewpoints (Silverman et al. 2016). Therefore they tend to isolate themselves and only react through a similar answer to the questions. Therefore the researcher could find out the impacts of groupthink if he or she receives similar viewpoints from multiple employees. If I face any kind of impacts of groupthink while conducting an interview with the focus group of senior managers, I would try to limit the impacts. In doing so, I would work with multiple subgroups and will avoid influencing them. Each of the members of the group should be valued and trusted. Also, I would one of the members of the group as Devils advocate; therefore it would be easier for me to gain their trust.

Randj Essay Example For Students
Randj Essay In William Shakespeares play Romeo and Juliet, there is much controversy to who is to blame for the deaths of Romeo and Juliet. In this tragedy, the two familys on-going feud drives Romeo to kill one of Juliets relatives and thus he finds himself banned from Verona. They then construct a plan to meet again, but when the plan goes awry, the two star-crossed lovers take their own lives. The question now, where to lay the blame of their deaths. The deaths can be blamed on the parents, the friar, or Romeo and Juliet. The parents of Juliet can easily be seen as the motive for their deaths. One reason for this is that they are pushing Juliet to marry Paris. Sir Paris, I will make a desperate tender of me childs love a Thursday, tell her she shall marry this noble earl(12-21). This section shows of Capulets agreement with Paris to have him marry Juliet. Juliet loves Romeo, and not Paris, but her fathers thoughts of Paris being a suitable match make it so she has to marry him. Juliet, not thinking into the future and what else could be possible, makes haste decisions after her father tells her, I tell thee what- get to church a Thursday or never after look me in the face. Speak not, reply not, do not answer(61-63), and goes to the friar looking to kill herself. Her father then later makes a decision to move the wedding up to Wednesday. This greatly upsets Juliet. The desire of her father for her to marry and calling her a wretch and hussy run Juliet into a corner with nothing left to do to save her self, except herself. Also, after Romeo kills Tybalt Juliets mom says, Ill send one in Mantua, where that same banished runagate doth live, shall give him such an unaccustomed dram that he should soon keep Tybalt company, and then I hope thou wilt be satisfied,(87-93). This gives Juliet the thought that Romeo will be killed if her parents can have anything to do with it and that she will have to live without him. Come, cords, come, Nurse, Ill to my wedding bed, and death, not Romeo take my maidenhead,(136-137) explains that Juliet would rather die a virgin rather than live without Romeo. The parents have proven many times how they could be the cause of the lovers deaths. We will write a custom essay on Randj specifically for you for only $16.38 $13.9/page Order now The Friar can also be blamed for the deaths. For one, he is the person that agrees to marry the lovers. In one respect Ill thy assistant be; for this alliance may so happy prove to turn your households rancor to pure love,(93-94). Though the friar may mean good, he can ultimately be traced back to their deaths. If he had not married them, than maybe Romeo and Juliet would have forgotten about each other, or ran away together, or solved their problems in other ways. The friar also could be blamed because he is the one that thought of the plan. By doing this, he foreshadows the deaths. He gives another complication to the plot, while he is still trying to do good. His plan, although it could work, probably is not plausible. This is seen by all the bends that have to take place in order for it to actually work. Hold, daughter. I do spy a kind of hopeAnd in this borrowed likeness of shrunken death, thou shalt continue two and forty hours and then awake from a pleasant sleepIn the meantim e, against thou shalt awake, shall Romeo by my letters know our drift and hither shall he come,(69-116). This tells of the friars plan and shows how outrageous it truly is. Lastly, Friar Lawrence could be to blame because he should have been there in the cell to stop Romeo from killing himself and then from Juliet also for killing herself. If he had been there, then Romeo would have never taken to poison because he would have known that Juliet was not really dead. He said that he was going to be in the cell waiting for Juliet to wake up, but he wasnt. When Romeo killed himself, it was just moments before Juliet woke up, so he should have been down there to save both of them. .u42b5b2b5b29e8a46b7541d33eac88146 , .u42b5b2b5b29e8a46b7541d33eac88146 .postImageUrl , .u42b5b2b5b29e8a46b7541d33eac88146 .centered-text-area { min-height: 80px; position: relative; } .u42b5b2b5b29e8a46b7541d33eac88146 , .u42b5b2b5b29e8a46b7541d33eac88146:hover , .u42b5b2b5b29e8a46b7541d33eac88146:visited , .u42b5b2b5b29e8a46b7541d33eac88146:active { border:0!important; } .u42b5b2b5b29e8a46b7541d33eac88146 .clearfix:after { content: ""; display: table; clear: both; } .u42b5b2b5b29e8a46b7541d33eac88146 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u42b5b2b5b29e8a46b7541d33eac88146:active , .u42b5b2b5b29e8a46b7541d33eac88146:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u42b5b2b5b29e8a46b7541d33eac88146 .centered-text-area { width: 100%; position: relative ; } .u42b5b2b5b29e8a46b7541d33eac88146 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u42b5b2b5b29e8a46b7541d33eac88146 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u42b5b2b5b29e8a46b7541d33eac88146 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u42b5b2b5b29e8a46b7541d33eac88146:hover .ctaButton { background-color: #34495E!important; } .u42b5b2b5b29e8a46b7541d33eac88146 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u42b5b2b5b29e8a46b7541d33eac88146 .u42b5b2b5b29e8a46b7541d33eac88146-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u42b5b2b5b29e8a46b7541d33eac88146:after { content: ""; display: block; clear: both; } READ: Karl Marx (1881 words) EssayLastly, Romeo and Juliet could be to blame for their own deaths.Many times, the couple act irrationally which ultimately leads them to death. Romeo has a very irrational and hasty personality. When seeing him for the first time, he has fallen for Rosaline, another girl, and he is all weepy and sad and end of the world-ish about his love for her. But then when Romeo meets Juliet, he immediately forgets about Rosaline. Our Romeo hath not been in bed tonight. The last is true; the sweeter rest was mine. God pardon sin! Was thou with Rosaline? With Rosaline, my ghostly father? No. I have forgot that name, and that names woe(43-47). Also, the childr en could be at fault because Romeo killed Tybalt. By doing this, he was banned from Verona and thus further upsets Juliet and now they have to go make a plan to get the two back together. If Romeo had not acted so irrationally, then he might not have killed Tybalt and then Juliets parents might not have had as big of a deal about the couple and hating Romeo. IF the children were more grown up, then they would have seen what the future could bring them and not had to make such haste decisions. Well, Juliet, I will lie with thee tonight. Lets see for means. O mischief thou art swift to enter in the thoughts of desperate men. I do remember an apothecary(34-37), tells of how Romeo heard of Juliets death and decides that he cant live without her and so he will kill himself to be with her. This passage shows again how the Romeo and Juliet could have been at fault for their own deaths. There are many to blame for the deaths, the parents, Friar Lawrence, and Romeo and Juliet, but each has its own good qualities of why it could be those people. It is really a personal decision on who is at fault and how you view the book. But either way, someone is do blame. Bibliography:

In Harper Lees Novel, To Kill A Mocking Bird You See That Maturatio Es
In Harper Lee's novel, ?To Kill A Mocking Bird? you see that maturation of some of the characters is clearly evident, particularly Scouts. You see this by the way she acts in front of Miss Maudie, Calpurnia and Mrs. Alexandra Finch. Beside her father, Scout respects and likes most Miss Maudie. They have a great relationship and they both love each other very deeply. When Scout first introduce us to Miss Maudie (in chapter 5), she tells us all the nicest things about her. She talks about how much she and Jem trusted Miss Maudie and what a good friend she was. They trusted her because she never told on them, never played cat-and-mouse with them, and because she was not at all interested in their private lives, (pg. 44-45) unlike most Maycomb people. This is also why Scout respected Miss Maudie so much and why she told her, Miss Maudie, you are the best lady I know (page 45) . Miss Maudie always made cakes for Scout, Jem and Dill, and she invited them over to eat them and also to play in her backyard. One summer, Scout spent the whole second half of the summer with Miss Maudie. They sat in the front porch, watched the sunset, talked, and took care of Miss Maudie's garden. That is when Scout became very close to Mis s Maudie. Scout admired Miss Maudie. Miss Maudie was her hero. Calpurnia is a very important character in the novel. Scout has known Calpurnia her whole life and basically lived with her, but they weren't very close. Scout never liked Calpurnia very much, mostly because she always complained about her behavior. She was always ordering her out of the kitchen, asking her why she couldn't behave as well as Jem when she knew he was older, and calling her home when she wasn't ready to come. There talking was like battling and one-sided. Calpurina always won, mainly because Atticus always took her side. Another reason why Scout did not like Calpurnia is because she made her practice writing. Then, when Scout's teacher in grade one found out that Scout can read, she got in trouble and blamed Calpurnia. At that time, she was too young to understand that Calpurnia only tried to help her and teach her so she would be literate and know more useful things. Even though this seems like a negative relationship and seems as if though it can never get better, the relationship between Scout and Calpurnia changes through the novel. As Scout grows and becomes more mature, she realizes that Calpurnia is nice and she always means good. On page 29, Scout tells us about her and Cal's conversation one day when Scout came back from school. Calpurnia said that she had missed Scout that day while she and Jem were at school. All of a sudden, Calpurnia was really nice to Scout. She let Scout watch her fix supper, she made crackling bread for her, and she even kissed her. Scout describes how she feels after all this behavior: I ran along, wondering what had come over her. She had wanted to make up with me, that was it. She had always been too hard on me, she had at last seen the error of her fractious ways, she was sorry and too stubborn to say so. (page 29). This proves that Scout always thought that Calpurnia never liked her and did not care about her, and that she deserves Cal's apology. Scout is deeply hurt when Calpurnia tells her that picking on Walter Cunningham while he eats at their place is rude and that Scout sh ould stop that and never do it again. Here, Scout thinks that Calpurnia is being mean to her again, but when she grows up a little, she will be thankful to Calpurnia because she taught her about being polite and respectful to her guests. There is, however, because of this, a positive side to this relationship. Scout does respect Calpurnia, partly because she has to - she is her nanny and she takes care of her, and partly because she simply likes some of Cal's characteristics. Scout likes Calpurnia because she has more education than

At times, you may be required to find solutions or write several opinions on various issues on which you are not very familiar with.Therefore, getting acquainted with the legal issues related to your state is a must. It is advisable to search for research papers related to legal issues in your state to learn the basic information abo ut the laws and the court procedures. You can find such research papers on the internet. Some of the websites have developed resources that help you understand the legal concepts.While writing the essays related to legal topics, you have to remember that you have to keep in mind the perspective of your readers. For example, you can include some comments and suggestions by the lawyer if he/she wishes.

Issues in Experimentation essays
Issues in Experimentation essays In replicating Sir Ronald Fishers famous experiment with tea tasting, it is essential for the subjects in the experiment to be blindfolded or, alternatively, presented with the cups of tea after they have been poured (Binomial coefficients..., 2006). However, given that when cold milk is poured into hot tea, the milk does not curdle (and when hot tea is poured into milk, the reverse occurs), the subjects would need to be blindfolded so that they could not see the curds and therefore guess correctly the order in which the tea and milk were combined. In Fishers experiment, the tea-tasting lady was given 8 cups of tea with milk, four of each version and was told that she would be tasting four of each variety (Preece, 1990). The experiment could be varied with respect to the number of each version of the beverage presented to subjects and with respect to random presentation of the samples; ideally, however, each version should be presented as frequently (if randomly) as the other. In any approach, it is likely that the subjects will identify the method used to combine the liquids correctly at least 50 percent of the time (Binomial coefficients..., 2006). The null hypothesis of the experiment reflects Fishers original hypothesis: The lady cannot tell the difference between milk poured into tea and tea poured into milk. The problem with the experiment is that there can be more than one mull hypothesis and, as significantly, the need to prevent subjects from viewing the cup with the beverage (Preece, 1990). Small samples that are statistically representative of a larger population are viable in experiments because one can extrapolate or project based on such studies to the larger population (Preece, 1990). When testing two populations with small sample sizes, the samples should be as nearly identical as possible if one is concerned with validity and reliability matters and if the lar ...

Describe and discuss how OSHA makes use of Section 5(a)(1) of the Act Assignment
Describe and discuss how OSHA makes use of Section 5(a)(1) of the Act - Assignment Example 1). For the clause to be invoked, there must be a hazard that is existing although there are consensus standards (as agreed upon) which exposes an employee to potential physical injury or even possibly serious harm such as hospitalization or death. Hazard here means danger, and it is quite subjective but as long as there is potential injury or harm, then a hazardous situation exists. The hazard must be recognized or evident, such as a construction worker who is above a scaffold that is ten feet high but working without a safety belt or no rails were being provided by the construction company. The law requires safety measures (belt or rails) for anyone who works at more than six feet in any construction-related project to prevent accidental falls. A fall at more than six feet height is very likely to cause serious physical harm, such as a broken arm, broken leg or a broken neck (resulting in paralysis) or even much worse, death (if the worker happens to fall head first). Just because no accident has happened yet does not mean a hazard does not exist, and the General Duty Clause is precisely intended to prevent accidents. The employer (construction firm) must provide abatement measures that will reduce or eliminate the hazard from an accidental fall, such as issuing safety belts or building those rails. It is feasible or easily doable by the company but may entail some additional expense on its

Becoming agile through mindfulness Dissertation
Becoming agile through mindfulness - Dissertation Example Organizations dealing with information systems development (ISD) have started shifting to agile methods. This has been necessitated by the fact that the previous traditional methodologies, such as waterfall methodology, have been restrictive in terms of processes and extensive planning (Lee & Xia, 2010). The agile manifesto has been derived from the following four main tenets; interactions and individuals over roles and processes, contract negotiation through customer collaboration, response to change over plan following and a working software rather than an exhaustive documentation. Through these four doctrines, the agile manifesto came up with 12 principles that have led to the creation of different other methodologies. Such methodologies as XP (eXtreme Programming), FDD (Feature Driven Development), DSDM (Dynamic System Development Method) and Scrum have had lots of support from leading industry practitioners. Agile practices can be fused with mindfulness to ensure effective deliv ery of software applications to customers. Mindfulness involves attention to changes and the surroundings during the software development process (Argote, 2006). Through mindfulness, it is possible to achieve a certain degree of flexibility that allows an organization to be strategically at an advantage compared to the others. Literature Review Agile Global Information Systems Development (GSD) Many Information Systems Development Companies are migrating to Agile methods as a way of coping with the increased demands placed on such organizations. Most of them have gone further ahead to introduce a substitute solution, Global Systems Development (GSD). This alternative has resulted in numerous benefits including an increased potential for innovations, reduced costs of software development, large pools of talent, reduced proximity to markets or clients, transfer of knowledge, division of work across sites and reduction in duration for developing the software especially due to the effec tiveness in time zones (Conchuir, Agerfalk, Olsson & Fitzgerald, 2009). According to Carmel and Agarwal (2001), firms and organizations should be well aware of challenges posed by the implementation of such methodologies. Just like Agile methodologies this area has not been well researched. The little research that exists on this area represents problem reports rather than extensive research that provide solutions in terms of significant techniques and practices (Smite, Wohlin, Gorschek & Feldt, 2010, p. 91). However, developing distributed or global software development through the use of Agile methods has been an area of great interest (Agerfalk, Fitzgerald & Slaughter, 2009). Such collaboration between distributed development and Agile methods has been conceptualized due to the capability that is produced when the two are fused together (Ramesh, Cao, Mohan & Xu, 2006). According to Turk, France and Rumpe (2002), such collaboration was regarded as highly unlikely. This was largely due to the fact that distributed development methods rely on formal methods while Agile methods are reliant on informal processes. Further research into this area has indicated that apart from the excellent blend that results from this collaboration, it is also possible to address issues of control and communication that arise during development of distributed systems (Ramesh, Cao, Mohan & Xu, 2006). This is an indication that Global Software Development is becoming much popular (Stotts, Nagappan, Baheti, Jen & A J, 2003). Such systems have
