ANSWER:
The Seasons: What if Earth’s Axis Tilt Were Different?
Learning Goal:
To understand how seasons would be affected by a greater or smaller axis tilt.
Introduction. What would happen to our seasons if Earth’s axis tilt were different from its actual 23.5°? This activity will help you answer this question and will also help you understand seasons on planets that have axis tilts different from Earth’s. As you examine the diagrams in parts A and B, keep in mind that Earth is always rotating, even though the diagrams do not show this rotation because they are not animated.
Part A - Each of the following figures shows Earth with a different axis tilt. (Assume that Earth’s rotation period is unchanged.) Each also shows a person located in Florida (not to scale). Rank the figures based on how much time the person spends in daylight during a 24 hour period, from most (Left) to least (Right).

Part B - The following figures are the same as those from Part A. This time, consider the seasonal differences that occur as Earth orbits the Sun with the different axis tilts. Rank the figures on the basis of the seasonal temperature differences you would expect between summer and winter, from the one with the most extreme seasonal differences (Left) to the one with the least extreme (Right). To rank items as equivalent, overlap them.

PSY 510 WEEK 6 ASSIGNMENT TIPS:
1. Describe the ethical issues involved in this situation.
2. Discuss any other concerns about the web developer/consultant’s strategies.
3. Explain some recommendations that you would make to the shelter.
The introduction section should present an overview of the topics to be covered in the paper. See rubric content criteria for required content. This section does not require a heading.
Use headings in the body of the paper, for organizational purposes; the conclusion should also have a heading.
First level headings should be centered, in bold. See APA guidelines: https://owl.english.purdue.edu/owl/resource/560/16/
Let us assume that the residents of this shelter are women and children who have been in domestic abuse situations, and there is counseling provided by staff at the residence.
In terms of ethical issues for this case, be sure to cover Standard 3.04 (Avoiding Harm) and four relevant aspects of APA Standard 5 (5.01, 5.02, 5.04 and 5.05).
As mentioned in the case study, the shelter has funding through NIMH. Consider the policies of this funding source.
Are there any legal issues that could be involved with the web developer's strategies?
In terms of recommendations, be sure these are a fit, given all ethical considerations described.
Should the current plans be adopted? If not, why not, and what would work better? Provide specific suggestions
|
Case Study: Ethical Consultation |
|
A local shelter that receives funding from the National Institute of Health and Mental Health is upgrading its website. Along with several upgrades to the website, the web developer/consultant makes a suggestion that the shelter add a testimonial page where local citizens can describe their positive interactions with the shelter and its services. Since the web developer/consultant want to get that page up and running first, the developer suggests using some positive ratings and responses from Angie’s List® and other similar ratings sites that already have positive stories and experiences with the shelter.
The director of the shelter loves the idea of a testimonial page. She thinks it would really add to the community feel of the shelter. However, knowing her funding source, she researches the APA Ethics Code and believes the shelter would be acting inappropriately. To discuss the matter in further detail, the director of the shelter calls you for an ethics consult.
In 500-750 words, explain the advice you would give:
1. Describe the ethical issues involved in this situation.
2. Discuss any other concerns about the web developer/consultant’s strategies.
3. Explain some recommendations that you would make to the shelter.
Use two to three scholarly sources to support your claims.
Prepare this assignment according to the guidelines found in the APA Style Guide, located in the Student Success Center. An abstract is not required.
