**Modeling** al Affiliation) Introduction The paper applies the second-order differential equations in variousreal life situations. Most of the questions involve the masses that bounce up and down at the spring’s end. The questions apply the accurate descriptions of the motion under various motions of situations. The work also introduces a lot of results and notions that are equally applicable in things that oscillate and vibrate in similar manner. For instance, the current analysis in fundamental circuit is analogous to analysis involving the spring’s mass. Discussion Diagram representing the (MSD) System Source: "Mass-Spring-Damper."

In the same manner the information system being developed should not be the automation of the current operational bad habits in the organization. Information System development should also include transforming the operation of the organization from being person or people centric to process and procedure centric as defined by its operating policies and business goals.

In information system development before starting the actual design of the system, we need to analyze and understand the requirement and the process of the organization and also the people that will be affected by the system. The system can either contribute to the organization’s success or it could also be the reason for the demise of an organization in case of i...

...FINANCIAL **MODELING** By of the of the School Briefly explain the conceptsof expected return, standard deviation, and correlation (in the context of share prices), and discuss their importance in portfolio management.
The fundamental concept behind Modern Portfolio Theory (MPT) is the fact assets in an investment portfolio should generally not be selected individually, each and every one on its own merits. It is very necessary to consider how each and every asset changes in price relative to how every other asset in the portfolio changes in price. The process of investment is basically a tradeoff between expected return and risk. Generally, it is thought that assets with much higher expected returns are more risky. For any given amount...

It also helps in reducing clustered and excessive data in a given setting to a manageable amount. It helps one to select on the precise variables that can be used in the study of managing a business. Therefore, it will help in making decisions of the business (Yao and Li 2013).

The variables in this technique helps in correcting certain mistakes that would otherwise been made in a normal business setting. For example, a business owner who thinks that extending business hours would certainly increase profits may re-think on this when they use the technique. This will go a long way in improving the business.

Linear regression is normally used with variables that are represented linearly. This will limit this technique to onl...

...FINANCIAL **MODELLING** Introduction In this report, we attempt to explore whether a company should introduce a profit sharing scheme for all employees. Two theoretical principles have been postulated before. One postulates that introduction of profit sharing scheme will improve employee satisfaction and organisational commitment. The other theory argues that there will be greater alignment of employee and employer interests if such a scheme is introduced. Six variables have been used to conduct a quantitative analysis. The variables are; Profit margin of company (expressed as a percentage), Total assets of company (expressed in £ millions), Extent of team working within the company (expressed as a percentage), Scheme (coded as 1 if company...

1) Title: Human Resources Management: **Methods** of Unbiased Appraisals
2) Study rationale:
The demands placed by potential employees for companies to meet have become increasingly high. Many of these demands include fair pay, health benefits, monetary compensation, and other incentives before a potential employee will accept a new position within any given organisation. This new level of demand has caused businesses to implement a department whose sole responsibility was to originally act as a portal between management and employees; keeping an objective point of view while trying to balance the needs of the company with the demands...

...Is it useful to use scientific **methods** to study the law? In answering the question “What is law?” Saint Augustine d: “Lex iniustanon est lex” (Unjust law is not law). This attributes a moral dimension to the law, which is disputed in the positivist approach that postulates legal validity as being conditioned by social facts rather than moral content. When applying a scientific approach to a study of law, the basic premise that holds good is the existence of certain immutable principles that condition our understanding of reality. According to Hans Kelson, the “law functions as a scheme of interpretation”1 and it is that system or set of rules that orders the manner in which we view the world.
Hence the study of law, when applied...

It was expected that the discussion would be about the costs associated with shrunken class size. That it is impractical to decrease the number of students to 30 since it will not improve their academic proficiency, but would only increase costs. Or if it does boost academic performance, it is too little to match the costs associated with that kind of class set-up. Simply stated, the cost of reducing class size to 30 is greater than the expected benefit. However, the proposal mainly dwelt on the ineffectiveness of reducing the class size, with no or minimal discussion on costs. The introduction creates a first impression on a written piece. That is why, short as it may be, the introduction should still brief and prepar...

Even though they have these similarities and have both been bestowed with the same title, these two historians drastically differed in their approaches.

Herodotus had another title bestowed upon him; he was also called the “Father of Lies.” Much of what is known of him has been gathered from his own writings as few other sources are available from his actual life. It should also be noted that the veracity of this information is in question as Herodotus was known to invent much in his own work, and it was sometimes the practice in Ancient Greece to attribute events from the life of one person to another; for instance, it has been questioned if the accounts of Herodotus’ exile are only due to the fact th...

Herein, comparisons will be made to highlight the differences in using anatomical models for study versus self-directed (usually textbook) learning. As well, the use of tutors as an advantage in the medical classroom will be discussed.

Some students are hands-on learners. For them, three-dimensional (3D) anatomical models are effective. “Exploratory tools enable users to investigate structures in ways not possible in the real world” (Implementing, para. 3). These 3D models can represent just about any part of the human body. Models are available of small structures, like the head, or of the entire human skeleton. Models of the entire human body can also be purchased. Some of them even have removable parts so...

Research ethics was maintained as the identity of the individuals participating was kept secret. As far as the validity of the study was concerned, the researchers attempted to use content validity in order to get an accurate response. The content validity focused on measuring off the ethnicities and gender percentages within the area and attempting to get a random sample of individuals via the phone. Their approach to random calling allowed for a significant random sample in the study. There were a few issues, however, with this type of approach. Those answering the phone sometimes were not always the desired individual, and not all of the desired people were surveyed. Different replacements did have to be used, and the attempt w...

Various calculating devices have long been used in Mathematics, but the computer offers an even greater potential. Some teachers are reluctant to use computers, for example on the grounds that it is an expensive option and not every child has access to one at home, but its prevalence nowadays means that students should be given the opportunity to use computers in their Mathematics lessons. They have the advantage of being able to make complex calculations much quicker, demonstrate graphical visualisations, instilling...

Accounting has always been a self-regulated profession. After the 2nd half of the 20th-century changes in accounting occurred due to the influence of private organizations such as the FASB. In the United States, accountants followed the generally accepted accounting principles (GAAP) to guide their everyday work. Accounting is a discipline that is very strict in its ways and does not welcome change well. In the aftermath of the Enron and WorldCom scandal, the government had to force change with the creation of the Sarbanes Oxley Act of 2002 due to a lack of trust in financial information.
