Week 2 – Assignment
Case Analysis – Integrating Theoretical Orientations
Prior to beginning this assignment, read the PSY650 Week Two Treatment Plan , Case 16: Attention-Deficit/Hyperactivity Disorder in Gorenstein and Comer (2014), and Attention-Deficit/Hyperactivity Disorders in Hamblin and Gross (2012).
Assess the evidence-based practices implemented in this case study by addressing the following issues:

Explain the connection between each theoretical orientation used by Dr. Remoc and the four interventions utilized in the case.
Consider Dr. Remoc’s utilization of two theoretical frameworks to guide her treatment plan. Assess the efficacy of integrating two orientations based on the information presented in the case study. Describe some potential problems with prescribing medication as the only treatment option for children with ADHD.
Identify tasks and positive reinforcements that might be included in Billy’s token economy chart given the behavior issues described in the case. (There are articles in the recommended resources that may assist you in this portion of the assignment.)
Evaluate the effectiveness of the four treatment interventions implemented by Dr. Remoc and support your statements with information from the case and two to three peer-reviewed articles from the Ashford University Library.
Recommend three additional treatment interventions that would be appropriate in this case. Use information from the Hamblin and Gross “Attention-Deficit/Hyperactivity Disorders” chapter to help support your recommendations. Justify your selections with information from the case.

Socw 6090 wk 5 discussion 1 – diagnosis of anxiety and obsessive | SOCW 6090 – Psychopathology for Social Work | Walden University

Discussion: Diagnosis of Anxiety and Obsessive Compulsive and Related Disorders
Social workers take particular care when diagnosing anxiety due to its similarity to other conditions. In this Discussion, you carefully assess a client with anxiety disorder using the steps of differential diagnosis. You also recommend an intervention for treating the disorder.
To prepare: Read the Nahla case study. Review the decision trees for anxiety and OCD in the Morrison (2014) text and the podcasts on anxiety. Then access the Walden Library and research interventions for anxiety.
Provide a discussion Post of at least 500-words which you address the following topics, content, and headings:
· Provide the full DSM-5 diagnosis for the client. Remember, a full diagnosis should include the name of the disorder, ICD-10-CM code, specifiers, severity, and the Z codes (other conditions that may be a focus of clinical attention). Keep in mind a diagnosis covers the most recent 12 months.
· Explain the diagnosis by matching the symptoms identified in the case to the specific criteria for the diagnosis.
· Discuss other disorders you considered for this diagnosis and eliminated (the differential diagnoses).
· Describe an evidence-based assessment scale that would assist in ongoing validation of your diagnosis.
· Recommend a specific intervention and explain why this intervention may be effective in treating the client. Support your recommendation with scholarly references and resources.
Note: You do not need to include an APA reference to the DSM-5 in your response. However, your response should clearly be informed by the DSM-5, demonstrating an understanding of the risks and benefits of treatment to the client. You do need to include an APA reference for the assessment tool and any other resources you use to support your response.

Research paper: supervisory skills | Accounting homework help

Instructions
Research Paper: New Supervisory Skills
Your research paper is based on the following scenario:
You have just taken over as a Shift Supervisor at Fast Fleet Shoes Manufacturing and have a team of 30 under you. Your educational and training level is exactly what you have today.
Your teams rotate shifts every 3 weeks and there are two shifts, morning, 0700-3:30 PM and evening, 3PM to 11:30PM. You have the flexibility to move people around shifts, and you stay on the same shift, with overlap (i.e. your hours are 9-6). Two co-leads take over when you are not there and stay on shifts with their workers.
The previous supervisor was let go for cause, failure to meet quotas and leadership inability. The department’s morale is very low and there is a great deal of pressure for your shift to perform.
On top of this, there is a problem with some of your employees, one is always late and the other calls in sick frequently (you can decide what factors lead to their absenteeism). The previous supervisor never did anything about this and everyone knew it was an issue. One of your co-leads has brought it to your attention and wants to know when you are going to fix it.
You also have an employee that has been there for 14 years and has never been promoted to co-lead or supervisor. He came to you and wants to know why? He is an older worker and knows what he is doing, however, one of your co-leads told you that some of the younger workers grumble that he is too slow and can’t learn new technology. He also stated that unless he gets the opportunity to move up, he’ll quit and make sure that management knows you never gave him a chance.
Finally, there is a brand new worker, a single mother, who is super sharp and a very hard worker. She told you on your first day there how much she loves working at the company and wants to progress upward. However, childcare is an issue and sometimes she needs to leave early. Currently no one does any work from home (your organization has not embraced it as a culture), however, in her position (she is inventory control) she feels she can perform this just as effectively from home several days a week and ask you if this is possible? What is your response?
You are to develop a solution to present to each of your co-leads on how to start fixing some of these issues. Make the paper informative, with some of the techniques and terms that we have addressed thus far in the course that deal with new supervisors. This about the terms leaders vs. managers, counseling, feedback, types of leaders, SMART objectives, SWOT, generational differences, Theory X and Y, MBWA, and favoritism. These terms are not all-inclusive and you are welcome to add others to support your solutions.
This can be a narrative paper, informative paper, a letter (albeit a long one) or a talking paper. You can use the first person to discuss what you think needs to be done. You can also assign tasks or take tasks away from co-leaders.
Your supervisor, co-leads, and workers can have fictional names, you can add in additional issues or factors and most of all, have fun and be creative in developing this workplace. Your co-leads can be good or bad at their job, you can decide how little or much you want to delegate to them as well as how much reporting back to you is needed.
Think about these challenges you will face as a new supervisor. You may want to break this into fixing immediate problems, a six-month goal, and one-year goal.
