...Enl 200 Oct. 16, 2014 Compare and contrast the theme of sexuality in three of the texts we’ve read so far. In several texts we have read in class so far there has been hidden meanings and in order to figure out these meanings we've had to analyze the context of the texts. One of the hidden themes we have found in several texts is that of sexuality. In the texts where it has been seen the most is that of the novel Dracula and in two Edgar Allen Poe poems, such as, "Annabel Lee" and "The Sleeper". These all have clear themes of sexuality in each though some parts are different, however, they all have similar traits. These three texts are alike not just because they have the theme of sexuality but they all deal with the death of a lady and how the main characters of these texts are attracted to their death which is preceived as uncanny. In the book Dracula by Bram Stoker Dracula is a vampire who finds a victim named Lucy who he sucks her blood until she dies when Lucy is dead she is still seen as beautiful by the characters and are all still in love with her although she is dead. In the poem "Annabel Lee" the character's love Annabel has died but he is still attracted to her and talks about her as if she is still alive and lays with her every night. The next poem "The Sleeper" is similiar to "Annabel Lee" because the main character has lost the love of his life a beautiful woman. The character like in "Annabel Lee" struggles to deal with the nature of life and death.......

To truly reap the benefits firstly one must be honest in the way that one self-assesses / evaluates Leadership is a diagnostic activity requiring a person to ask, in each situation, “What is the maximum and unique value that a leader could bring to the situation?” The obvious value of this insight is best reflected in the enormous industry that has emerged around this theme, including the most popular of these, the Situational Leadership Model (e.g. Hersey, Blanchard, and Natemeyer, 1979). (Nohria.N & Khurana.R 2010, page 161.) Once a leader has self-assessed / evaluated themselves they can focus on their weaknesses that require improvement. After self –assessment / evaluation has been carried out they can then start to lead in a stronger manner; motivating and inspiring others, leading from the front and by example. In doing so the leader will earn the respect from their team / group. Being a strong leader is best achieved with the respect given by those being lead. A leader who has not earned the respect of the team will not be as...

...1. List and describe the four basic financial statements included in a corporate annual report. The balance sheet shows the financial position—assets, liabilities, and stockholders' equity—of the firm on a particular date, such as the end of a quarter or a year. The income statement presents the results of operations—revenues, expenses, net profit or loss and net profit or loss per share—for the accounting period. The statement of shareholders' equity reconciles the beginning and ending balances of all accounts that appear in the shareholders' equity section of the balance sheet. The statement of cash flows provides information about the cash inflows and outflows from operating, investing, and financing activities during an accounting period. 2. In a speech by Arthur Levitt, chairman of the SEC, he states: "Managing may be giving way to manipulation; Integrity may be losing out to illusion." Using examples, explain the meaning of this quotation. Levitt is referring to earnings management, the practice of using accounting choices and techniques in such a way that earnings reports reflect what management wants the user to see, instead of the true financial performance of the firm. Five techniques are commonly used to create illusions according to Levitt. They are "Big Bath" restructuring charges, creative acquisition accounting, cookie jar reserves, misuse of materiality concept and incorrect revenue recognition. 3.......

List, describe, and provide an example of each of the five characteristics of high quality information.   High quality information is; Accurate- Information that contains all properly spelled names, words, dates, etc. The accuracy of information is important for many reasons such as a package delivered properly to a customer, a return phone call regarding a customer service issue, or a misplaced decimal point on a bank deposit slip. Any of the previously mentioned mistakes, by the customer or the employee, could result in a loss of business or profits. When developing IT systems, there are certain conditions available to a programmer that can help minimize these easily made mistakes. One example of such a condition would be creating a rule that 5 digits must be entered when asking for a consumer’s zip code. Completeness- Any information that is incomplete will prevent accurate results. Imagine a medical survey with a cell requesting a person’s date of birth. If the survey only captures the day and month of birth, the information available will not include the samples actual age, only their day and month of birth. This could prevent the employee from maintaining the average age of the consumers....

...Mid Term Paper Question #5, page 225 HR590 Human Resource Management Keller Graduate School of Management of DeVry University July 28, 2011 Part 1 of question #5: Based on my quick research I’ve come to realize that most internal recruiters, at least in medium to large sized companies, commonly rely on web-based systems to do the initial screening of applicants. They tend to lack incentives, and also lack penalties, for how well they recruit. With external recruiters, there are often no metrics in place at all, other than time to fill. If metrics for quality of hire are clearly tracked and compared between internal and external recruiters, it can help identify the best recruitment model for a business because as an Human Resources (HR) person you will be able to tell who is providing the highest-quality candidates. Part 2 of question #5: Internal recruitment efforts can provide a business with a solid pool of applicants. Through internal job postings and communications, small businesses can locate candidates with the appropriate mix of talent and experience. Those with a solid track record of demonstrated success related to achievements, dedication and performance represent ideal candidates for internal recruiting.

...Juvenile sentencing guidelines are designed to establish a process through which juvenile offenders have the opportunity to access a variety of resources to allow for rehabilitation and being let back into the community as a law abiding citizens.Up until the mid-point of the 20th century, the sentences imposed on juveniles in the court system were similar to those just like adults convicted of crimes. Sentences given to juveniles emphasized punishment over rehabilitation during this time period. Ultimately, juvenile sentencing changed from punishment to rehabilitation, something that continues to this day. This is an introduction to Juvenile Justice in America. Since the 1990s, youth crime rates have gone up . These falling crime rates have led many jurisdictions to rethink the juvenile justice practices that happen in the 1980s and 1990s. Today, states are using major reforms designed to reduce institutional confinement, closed old 19th century era reform schools, and expand community-based interventions.In the late 18th and early 19th century, courts punished and confined youth in jails and penitentiaries. Since few other options existed, youth of all ages and genders where often confined with hardened adult criminals and the mentally ill in large overcrowded institutions. At the same time, American cities were dealing with high rates of child poverty and neglect putting pressure on city leaders to find a solution to this growing social issue....

For over decades, people from all over the world keep coming into the United States seeking for better life for themselves, and most importantly for their spouse, their children and even their children's children. However, not every immigrant comes into this country through legal procedure and most of these illegal immigrants are poor and uneducated people. They might be brought here because of human trafficking, smuggling or other methods. There’s been many debates regarding helping these illegal aliens to become citizens to our America. Should congress make it uncomplicated for migrants o become citizens or, should congress keep the hardship of earning theirs? Easy legal ship for immigrants has been a humongous controversy for decades to come. For years to come, this country has been split 50/50 on this topic and from the recent years, hasn’t reached a decision yet. There have been many views on ways to make citizenship easy. One of them that caught my eye has captured my consideration mentioned a lot about the age groups of these foreigners. The Pro-immigration groups are pushing congress to provide conditional legal status to immigrants who came to the United States at the age of 10 and have lived here for at least five years.
