74. DDT is a pesticide that has been banned from use in the United States and most other areas of the world. It is quite effective, but persisted in the environment and over time became seen as harmful to higher-level organisms. Famously, egg shells of eagles and other raptors were believed to be thinner and prone to breakage in the nest because of ingestion of DDT in the food chain of the birds.

 

An experiment was conducted on the number of eggs (fecundity) laid by female fruit flies. There are three groups of flies. One group was bred to be resistant to DDT (the RS group). Another was bred to be especially susceptible to DDT (SS). Finally there was a control line of non-selected or typical fruitflies (NS). Here are the data:

Boehm corporation has had stable earnings growth of 8% a year for the

FIN 534 – HOMEWORK SET #5

Use the following information for Questions 1 and 2:

Boehm Corporation has had stable earnings growth of 8% a year for the past 10 years and in 2013 Boehm paid dividends of $2.6 million on net income of $9.8 million. However, in 2014 earnings are expected to jump to $12.6 million, and Boehm plans to invest $7.3 million in a plant expansion. This one – time unusual earnings growth won’t be maintained, though, and after 2014 Boehm will return to its previous 8% earnings growth rate. Its target debt ratio is 35%.

Calculate Boehm’s total dividends for 2014 under each of the following policies:

1.       (a)   Its 2014 dividend payment is set to force dividends to grow at the long – run growth rate in earnings.

(b) It continues the 2013 dividend payout ratio.

2. (a) It uses a pure residual policy with all distributions in the form of dividends (35% of the $7.3 million investment is financed with debt).

(b) It employs a regular – dividend – plus – extras policy, with the regular dividend being based on the long-run growth rate and the extra dividend being set according to the residual policy.

Use the following information for Questions 3 and 4:

Schweser Satellites Inc. produces satellite earth stations that sell for $100,000 each. The firm’s fixed costs, F, are $2 million, 50 earth stations are produced and sold each year, profits total $500,000, and the firm’s assets (all equity financed) are $5 million. The firm estimates that it can change its production process, adding $4 million to investment and $500,000 to fixed operating costs. This change will (1) reduce variable costs per unit by $10,000 and (2) increase output by 20 units, but (3) the sales price on all units will have to be lowered to $95,000 to permit sales of the additional output. The firm has tax loss carryforwards that render its tax rate zero, its cost of equity is 16%, and it uses no debt.

3.       What is the incremental profit? To get a rough idea of the project’s profitability, what is the project’s expected rate of return for the next year (defined as the incremental profit divided by the investment)? Should the firm make the investment? Why or why not?

4.       Would the firm’s break-even point increase or decrease if it made the change?

Strengths and Weaknesses of the DSM-5

Though the DSM-5 is the standard manual for mental illness diagnoses, it is not without weakness. In this Assignment, you analyze the strengths and limitations of the DSM-5 diagnostic system, and you differentiate between normal behavior and diagnosable symptoms using the concepts of dimensionality and spectrum.

To prepare: Review the concept of the dimensional approach with the DSM-5 and review the methods that the DSM-5 recommends to individualize where a person fits on a continuum of their illness in terms of subtypes, severity, and functional impairments. You will find these classifications in different parts of the manual and begin to be comfortable looking through it.

Next, imagine the following scenario:You are a school social worker who has been asked to address a parent-teacher association meeting. Many parents in the audience have children who have been identified for special education services. They are confused about how to understand the diagnoses they are seeing. Others have worries about over diagnosis. You have been advised that while these parents are generally well-informed, many don’t understand the dimensional or spectrum aspects. All are worried.
You will start with your introductory talk to the parents on these factors. After you provide your explanation, imagine that you open the meeting to questions. You will address the question noted below that is posed by a parent in the audience. Consider your audience, and practice explaining in terms a non-professional might understand.

  • 1. Briefly describe what the DSM-5 is and how it is organized. In your description, define the concepts of spectrum and dimensionality as explained by Paris and in the DSM-5 introduction.
  • 2. Explain why social workers and mental health professionals use diagnoses and what receiving a diagnosis means (and does not mean).
  • 3. Explain general concerns about the risks of  and misdiagnosis versus not diagnosing. Also explain how diagnosis is connected to services.
  • 4. Explain other details that might help your audience understand the strengths and weaknesses of the diagnostic system.
  • 2.Provide a response to the following parental questions:
    • My teenager’s best friend died by suicide this year. It’s been months, and she doesn’t seem over it. Her teachers tell me she should get help for depression, but I think it’s just grief. She talks about her friend all the time and gets very upset. I am worried about her. Is it normal for her to still be feeling this way? I don’t want to put her on medication for normal feelings. What is the difference between grief and depression?

Altered physiology | Nursing homework help

 With a place squarely in the spotlight for patients diagnosed with all manner of disease, APRNs must demonstrate not only support and compassion but the expertise to guide patients’ understanding of diagnoses and treatment plans.

This expertise goes beyond an understanding of disease and sciences, such as cellular pathophysiology. APRNs must become experts in their patients, understanding their medical backgrounds, pertinent characteristics, and other variables that can be factored in their diagnoses and treatments.

Develop a 3- to 4-page case study analysis in which you:

  • Explain why you think the patient presented the symptoms described.
  • Identify the genes that may be associated with the development of the disease.
  • Explain the process of immunosuppression and the effect it has on body systems.
