An IEP is created for students who have been classified with a disability and are between the ages of 3 and 21. An Individualized Education Program (IEP) is a written statement of the educational program designed to meet a child’s individual educational needs. Every child who receives special education services must have an IEP. An individualized education program has the goal of setting reasonable improvement learning goals for a child for one year including the role the school will assist the student to achieve their specific goals (Gibb & Dyches, 2016). The IEP is developed by a team that meets and discusses the relevant information about the child's strengths and deficiencies. The team meets, in order to analyze the data obtained by gathering data and individual assessments data about the child. The team then develops specific educational interventions educational to address the child’s educational deficiencies that result from his or her disability. This team meets at least once a year but as often as needed to ensure that the child’s educational needs are being met. The IEP has two important roles. The first is the special education plan...

Contributors:Elyssa Tardiff, Allen Brizee. Summary: This resource describes why outlines are useful, what types of outlines exist, suggestions for developing effective outlines, and how outlines can be used as an invention strategy for writing. Four Main Components for Effective Outlines Ideally, you should follow the four suggestions presented here to create an effective outline. When creating a topic outline, follow these two rules for capitalization: For first­level heads, present the information using all upper­case letters; and for secondary and tertiary items, use upper and lower­case letters. The examples are taken from the Sample Outline handout. Parallelism—How do I accomplish this? Each heading and subheading should preserve parallel structure. If the first heading is a verb, the second heading should be a verb. Example: I. CHOOSE DESIRED COLLEGES II. PREPARE APPLICATION ("Choose" and "Prepare" are both verbs. The present tense of the verb is usually the preferred form for an outline.) Coordination—How do I accomplish this? All the information contained in Heading 1 should have the same significance as the information contained in Heading 2. The same goes for the subheadings (which should be less significant than the headings)...

Defining and framing the Issue –You need to identify the underlying reasons why the issue has arisen in the first place (the ‘why’? question). As part of this, you will need to frame the issue in relation to the current practices with management functions (including supporting theory/theories) that may have contributed to the issue. You should include some consideration of any relevant environmental factors (internal/external) that may have influenced the issue. 3. Addressing the Issue – You need to show how you will address the underlying reasons that have contributed to the issue by outlining changes to the existing practices with the identified management functions (the ‘how’? question). Your arguments need to be supported with reference to theory/theories that endorse the new approach. 4. Conclusion – You need to provide a summary and evaluation of the key findings of the report.

Other calculations include rates of return on Shareholders Equity and Total Assets and earnings per share to name a few. All calculations can be found in the appendices. Results of data analysed show that all ratios are below industry averages. In particular, comparative performance is poor in the areas of profit margins, liquidity, credit control, and inventory management. The report finds the prospects of the company in its current position are not positive. The major areas of weakness require further investigation and remedial action by management.Recommendations discussed include:  improving the average collection period for accounts receivable·   improving/increasing inventory turnover·   reducing prepayments and perhaps increasing inventory levels The report also investigates the fact that the analysis conducted has limitations.

We’ll be exploring the world of statistics from a business perspective this week, allowing you to practice your skills with descriptive statistics, formatting, graphs, and regression analysis. As discussed in the lesson, the value of statistics lies in the ability to analyze data more effectively for the purpose of improving decision making. You might have heard the expression that “statistics never lie, and only liars use statistics”. There is an obvious truth in this statement, in that, depending on the questions being asked and the data collected, the statistics can skew reality. For example, it is true that as ice cream sales increase, accidents at swimming pools increase. Does this mean that the more ice cream that is sold, the more accidents it causes (correlation/causation)? Of course not, but the data, if not interpreted correctly, could lead to false conclusions. It just so happens that both are correlated to a rise in temperature in the summertime. The hotter it is outside, the more kids flock to swimming pools, leading to more accidents, and the more ice cream is sold. So you see, although statistics are vital in the world of decision making, you have to be wise, and ask the right questions. Software...

Torts and Personal Injury Scenerio

...The judge asks you to prepare an essay, explaining to her why, under Illinois law, she should grant or dismiss the motion for summary judgment. Please help the judge. CASE SCENERIO: The plaintiff Alan was trying to catch a plane at Chicago's O'Hare Airport. He knew that he was late for his plane and so, he was running through the airport as fast as possible. Unfortunately, Alan does not see the banana peel that was lying on the floor in the middle of the concourse. He slipped on the banana peel and went sliding across the floor. He banged his head on a metal counter and suffered a severe head injury. Alan now files a lawsuit against the airport, which, we will assume, is in charge of maintaining the concourse, alleging negligence on the part of the Airport. A subsequent investigation revealed that the banana peel was brownish when Alan slipped on it. Alan states that he has no idea where the peel came from and why it ended up where it did. The Airport moves for summary judgment on the grounds that Alan has not alleged any evidence of negligence on the part of the airport. The Airport claims that it has no idea how the peel got there, but it could have been dropped a moment ago by another passenger, and that Alan can't disprove this possibility. The issue that must be decided is whether the airport’s motion for summary judgment should be granted or dismissed. Alan bears the burden of proving that the banana peel had in fact been lying in the...
