You are asked to evaluate employees’ exposures to methyl n-amyl ketone during a painting operation. After careful consideration, you choose NIOSH Method 2553 for the sampling. 

You can access the method by clicking the link below:

National Institute for Occupational Safety and Health. (2003). Ketones II: Method 2553. In P. M. Eiler & M. E. Cassinelli (Eds.), NIOSH manual of analytical methods (4th ed.). Retrieved from http://www.cdc.gov/niosh/docs/2003- 154/pdfs/2553.pdf

Your pre-sampling and post-sampling pump calibrations using a primary standard are both 0.05 L/min. 

You collect personal samples on two employees working in the operation. 

The samples are collected for 430 minutes (Sample 1) and 440 minutes (Sample 2).

1. Calculate the sample volumes for each of the samples.

The laboratory reports that the front section of Sample 1 contains 5,000 μg of methyl n-amyl ketone and the back section contains 200 μg of methyl n-amyl ketone. The front section of Sample 2 contains 4,000 μg of methyl n-amyl ketone and the back section contains 50 μg of methyl n-amyl ketone. Neither the front nor back sections of the field blank you supplied contain any detectable levels of methyl n-amyl ketone.

1. Calculate the concentrations of the two personal samples in μg/L and mg/m3. 

2. Convert the result to ppm (MW for methyl n-amyl ketone = 114.2).
3. Show all the steps for your calculations.

You then reference OSHA’s Table Z-1 and find that the 8-hour TWA PEL for methyl n-amyl ketone is 100 ppm

1. Discuss how the results of the two personal samples you collected compare to the OSHA PEL, and describe the sampling method you implemented.
2. You also look up the ACGIH TLV for methyl n-amyl ketone and find that the TLV is 50 ppm as an 8-hour TWA exposure.
3. Discuss how the results for the two personal samples compare to the ACGIH TLV.
4. Discuss whether you would recommend comparing the results of your sampling to the OSHA PEL or the ACGIH TLV.
   Include your rationale for the choice, and explain how you would rationalize your choice to your employer.

The case study should be a minimum of three pages in length, and you should cite the NIOSH document using APA style.

Objectives

Upon completion of this week, you will be able to:

• Explain the primary means of ensuring personal safety prior to the establishment of formal, organized police departments.
• Discuss the influence of the English police experience on American policing.
• Characterize the regional differences in American policing prior to the 20th century.
• Describe how the turbulent times of the 1960’s and 1970’s influenced American policing.
• Identify at least four events or people instrumental in the development of 20th-century American policing, and describe their influence.
• Explain the issue of sworn law enforcement employee averages and give some examples of them.
• Compare and contrast the major problems affecting metropolitan small-town, and rural law enforcement.
• List some benefits of the joint task force approach to law enforcement.

Each assignment will consist of a posting of a relevant news article or media or story relating to the topics for the week. The students will upload the topic with a link to the article or story and discuss the relevancy to the readings. 300 word minimum. [LO 1-9]

To Prepare:

• Choose a specific group work scenario that you either encounter regularly or that is of particular professional interest to you (e.g., group social work within hospitals, youth groups in schools, substance abuse co-led groups in prisons).
• Review Chapter 12, “Ethical Issues in Group Work,” in the Corey course text, and reflect on the guidelines related to your chosen scenario.

The Assignment (2-3 pages):

• Briefly describe the group scenario that you are using for the Assignment.
• Explain the skills necessary to be a successful group facilitator for this population and/or issue type and within your chosen setting.
• Explain the ethical and cultural issues that must be addressed before you can begin a group in this scenario.
• Identify the three most important guidelines for multicultural and social justice competence that would guide you professionally and ethically once the group was underway. Explain why you selected these guidelines in particular.
• Of the three guidelines you described, explain which one(s) you believe you need to develop additional knowledge or experience with as part of your professional development and why.

• Review the Greer et al. (2017) article (located in this week’s Learning Resources). Reflect on policy formation and how media coverage of news events impacts public policy.
• Select a media resource that is related to health advocacy and public policy (e.g., YouTube video, TedTalk, film, etc.)
  • Note: Do not select an article for this Discussion.
• Identify an idea or policy initiative from your selected media resource and consider how it originated (e.g., individuals, organizations, politicians, etc.).
• Think about the impact of your selected media resource’s idea or policy on health advocacy and public policy.

Post a comprehensive response to the following:

• Briefly describe your selected media resource.
• Describe the idea or policy initiative that was promoted by your selected media resource.
• Explain how the initiative originated.
• Explain two potential impacts of the media idea or policy initiative on health advocacy and public policy.

Be sure to support your postings and responses with specific references to the Learning Resources.

Moving through multiple time zones during a duty period is a regular occurrence for many airline, business aviation, and military flight crewmembers. Present your view on whether it is better to resynchronize on a natural schedule or use technology like chronobiological light therapy to adjust quickly to local time. Explain your rationale and provide at least one scholarly source to support your position. Post your explanation (using APA format where applicable).
