Discussion: Dalia’s Behavior

Discussion: Dalia’s Behavior

Argumentative behavior, engagement in physical altercations, and evidence of mood swings can all indicate that an adolescent is experiencing anger and depression. Self-harming can surface in adolescents, too, as they experience difficult emotions.

For this Discussion, read the case study of Dalia and consider what you, as her social worker, would do if you observed self-harm indicators.

By Day 3

Post a brief explanation of self-harming behaviors that Dalia is exhibiting. Describe theoretical approaches and practical skills you would employ in working with Dalia. How might familial relationships result in Dalia’s self-harming behavior? Please use the Learning Resources to support your answer.

USE APA format using references from the listed sources provided

Working With Children and Adolescents: The Case of Dalia ( I have Attached the case summary)Working With Children and Adolescents: The Case of Dalia

Dalia is a 14-year-old, biracial female of African and Irish American descent who resides with her parents in a middle-class suburb. She is the youngest of three children and is currently the only child remaining in the home. Dalia’s parents have been married for 25 years. Dalia’s father works in the creative arts field with a nontraditional work schedule that has him gone overnight and sleeping late into the morning. Dalia’s mother is an executive who works long hours. Dalia was diagnosed with sickle cell anemia in early childhood and was hospitalized multiple times. At present, Dalia’s health is stable with the last serious episode occurring 2 years ago.

Dalia’s parents reported that until middle school, Dalia was an easygoing, good-natured youngster who enjoyed singing and participating in activities with her peers and family. Dalia denied any problems with drugs or alcohol but admitted to drinking with friends. Dalia described her family relationships as tense, stating, “My dad lets me do what I want” and “My mother is always trying to control me.” Dalia described her relationship with her older brother, who lives in another state, as “cool,” and her relationship with her older sister, a college sophomore, as “not cool.”

Dalia’s parents sought out counseling services for behavioral issues on the recommendation of her school. The issues included argumentative behavior with authority figures, physical altercations with peers, poor concentration in class, irritable mood, verbal combativeness when confronted, truancy, and highly sexualized behavior with male peers. At home, Dalia had become more argumentative and physically threatening. Her parents had discovered that she and her friends drank alcohol in their home. Dalia’s parents also reported that she was up most of the night and slept most of the day. They also reported that her mood was highly irritable and that she was extremely impulsive. She had no interest in getting involved with any extracurricular activities, stating that those things are “corny and boring.”

In the first meeting, Dalia and her mother both appeared agitated with each other and became argumentative when going through the intake information. Dalia quickly told me that she was not planning to talk about anything because this meeting was her parents’ idea. She stated, “I don’t have any problems, my parents do.” Soon into this first visit, Dalia blurted out that her mother was upset with her because she had just shown her a tattoo she had had done recently, purchased by using a fake ID. I acknowledged her news and asked if this was the way that she usually shared important information with her mother. Dalia shrugged and stated, “I don’t know. I figure I better her tell her now before she gets too busy.”

I asked both Dalia and her mother what their expectations were for counseling and what each would like to get from these visits. Dalia’s mother seemed surprised and stated, “This is for her. She better change her attitude and start to focus on school.” I explained that often it is helpful to have sessions both individually and with family members. I pointed out that because family issues were identified it might be productive to address them together. Dalia’s mother agreed to attend some meetings but also stated that her time was limited. I was told that Dalia’s father would not be able to join us because he was never available at that time.

Dalia and I began sessions alone, and her mother joined us for the second half. During the family sessions, we addressed the communication breakdown between Dalia and her mother and Dalia’s at-risk behaviors. Individual sessions were used to address her impulsive behavior and self-esteem issues.

In individual sessions, Dalia talked about how the family had changed since her sister left for college. She said her parents stopped being present and available once her sister went away to school. She said she spent more time on her own and her behavior was under more scrutiny. Dalia also talked about her sister, describing her as an excellent student and very popular. She said her teachers in middle school would often compare Dalia to her sister, making her feel unsuccessful in comparison. During a family portion of a session, Dalia’s mother initially disagreed with Dalia’s point of view regarding how the family had changed, stating, “She’s just trying to trick you.” I encouraged them to discuss what was different about the family dynamics now compared to when the older sister was at home. We discussed how the family had changed through the years, validating both perspectives.

In time, I was able to have Dalia’s father join us in some of the family meetings. He said he felt Dalia’s behaviors were just a stage and part of being a teenager. Dalia’s parents disagreed openly in our sessions, with each blaming the other for her behavioral issues. During these sessions, we addressed how they each may have changed as their children matured and left home and how this affected their availability to their youngest child. I helped them identify what made Dalia’s experience distinct from her siblings’ and examine what her high-risk behaviors might be in reaction to or symptomatic of in the family.

In the course of the family work, the realities of being a biracial family and raising mixed-race children were also addressed. We discussed how the parents navigated race issues during their own courtship and looked at the role of acculturation and assimilation with their children in their social environments as well as respective families of origin. Educating both parents around race and social class privilege seemed fruitful in understanding distinctions between what they and their children may have faced.

After 12 weeks it was agreed that therapy would end because Dalia would be starting high school and the family felt better equipped to address conflict. The family had made some changes with the household schedule that increased parent–child contact, and Dalia agreed to more structure in her schedule and accepted a position as a camp counselor in a local day camp for the summer. Termination addressed what was accomplished in this portion of therapy and what might be addressed in future counseling. The termination process included reviewing the strategies of conflict resolution and creating opportunities for family contact and discussion in order to reinforce those behavioral and structural changes that had led to improved communication and conflict reduction.

Economic Analysis

Critical analysis of basic economic markers can be very revealing of an airline’s financial health. For this assignment, research an airline’s most-current financial data, analyze the data, and report your findings.

Most airlines are public companies (as compared to private companies) and, usually, public companies are required by securities regulators to make financial information available to the public. This gives students and other researchers open access to audited information via annual and other reports. This information is generally available from the airline’s website; look for “About Us” or “Investor Relations” links in your research. For U.S. companies, look for the most recent SEC Reports. An annual SEC report (called a 10K report) is an audited report containing all of the company’s financial data.

For this discussion, select a public airline, find its most current annual financial information, and look for some of the key terms discussed in Activity 5.1. Then, in an essay of 200–300 words, analyze the figures you found, noting trends and relationships. For example, you might find a company with high costs (CASM) and low fares (yield), resulting in a very high BLF (near 1.0). A high BLF will put pressure on marketing to keep seats filled. Another company might have PRASM less than CASM; meaning ancillary revenue (like baggage fees) will be very important to maintaining a profit.

Aviation Economic Terms

Available Seat-Mile

One seat flown one mile (also called capacity available).
A 100-seat aircraft that flies a 100-mile flight produces 10,000 ASMs.

Total annual ASMs represent the airline’s total production or capacity. ASMs are what the airline produces; as an analogy, if shoe factories produce shoes, airlines produce ASMs.

Total annual ASMs are expressed in very large numbers, usually billions for a large airline or cargo carriers.

Cargo carriers use a similar term: Available ton-miles. An available ton-mile (ATM) equates to a ton of carrying capacity multiplied by miles traveled.

RPM

Revenue Passenger-Mile

One paying passenger flown one mile (also called capacity used or traffic)
A 100-seat aircraft that flies a 100-mile flight with 90 people onboard produces 9,000 RPMs.

RPMs represent the amount of production the airline sells. RPMs are the airline’s “demand.”

Total annual RPMs are expressed in very large numbers, usually billions for a large airline or cargo carriers.

The cargo carriers’ term is RTM, or revenue ton-mile. The RTM equates to a ton of actual cargo multiplied by miles traveled.

LF

Load Factor

RPM divided by ASM (also called capacity utilization).
It’s simply the percent of the carrier’s seats that are filled.

Load factor can be thought of as capacity used (RPM) divided by capacity produced (ASM).

Another associated term is “Breakeven” Load Factor (BLF). Breakeven Load Factor is the percentage of seats the airline has to fill to break even. It’s calculated by dividing CASM by Yield. (An airline that has a breakeven load factor above 1.0 will lose money even if they sell every seat on every flight unless they have ancillary sources of revenue other than passenger fares.)

Cutting capacity by halting some unpopular (low load factor) flights will usually result in an overall load factor increase. (Taking low-load factors out of the total will increase the average.)

Load Factor is expressed as a percentage.

RASM

Revenue per Available Seat-Mile

Operating (total) revenue divided by ASM (also called unit revenue)
It’s the amount of revenue the airline earns for each seat they produce.

Sometimes airlines report Passenger RASM (called PRASM), which is passenger revenue divided by ASM. This accounting term helps the company distinguish between passenger and cargo/ancillary economic trends. (PRASM can also be calculated as yield x load factor.)

RASM is expressed in cents.

CASM

Cost per Available Seat-Mile

Cost divided by ASM (considered the unit cost of production)
It’s the cost incurred to produce one unit of production and indicative of the production efficiency.

A sub-unit of CASM sometimes reported is “CASM Ex-Fuel.” Airlines often consider fuel expenses beyond their control, so they report CASM Ex-Fuel to identify trends in “controllable” expenses.

Consider the CASM – ASM relationship. If an airline increases capacity (ASM), total costs will also go up, so you would think CASM would stay about the same. However, fixed costs will be spread out among more ASMs and the result might be a slight reduction in CASM.

CASM is expressed in cents.

Yield

Yield

Passenger revenue divided by RPM

Yield equates to the average revenue per unit of demand (in other words, the average amount a passenger pays per mile flown). Yield and Load Factor usually vary inversely – if yield goes up, load factor usually goes down. (A better indication of an airline’s true revenue situation is PRASM which is the product of yield and load factor.)

High yield means the airline is getting the most for their sold seats. However, yield says nothing about how many seats the airline sells, so yield, alone, tells nothing about the company’s profitability.

Yield is expressed in cents

Evaluate the current financing and reimbursement models within the U.S. healthcare delivery system.

Competency

Evaluate the current financing and reimbursement models within the U.S. healthcare delivery system.

Scenario

The Titusville Medical Center, a mid-sized, 300 bed, not-for profit hospital, has hired you as an expert consultant for healthcare financing. They have requested an executive summary that explains to their senior leadership (administrators and medical staff) the current financing and reimbursement models within the U. S. healthcare delivery system. Titusville is on the verge of buying either Jackson or Abigail Hospital and must understand financing and reimbursement models in order to know the best acquisition to consider.

Jackson Hospital is a 300 bed, not-for-profit, serving an urban, low-income population. Accepts all government payer types and most private insurances. Specialty populations served include hospice, rehabilitation, wound care, cancer care, and hospital-based imaging center.

Abagail Hospital is a 400 bed, for profit serving an urban, middle-income population. Accepts all government payer types and most private insurances. Specialty populations served include psychiatric, rehabilitation, and cancer care.

Instructions

Compose an executive summary that provides an in-depth analysis of the changing dynamics of healthcare reimbursement and the associated funding sources. Your executive summary should include an examination of the current financing and reimbursement models within the U.S. healthcare delivery system in order to help the merger committee decide whether to acquire either Abigail or Jackson Hospital. Among the most common reimbursement models are capitation, Pay-for- Performance (P4P), bundled payments, Accountable Care Organizations (ACOs), Patient-Centered Medical Homes (PCMH), Fee-for-Service (FFS), Shared Savings, and Shared Risks.

Be sure that the executive summary includes eight types of healthcare payment models (of at least two paragraphs each) as well as a title and reference page.

For each model, include a description of:

  • The incentive(s) and drawback(s) for healthcare providers using the model
  • The incentive(s) and drawback(s) for patients who have providers using the model
  • Required quality metrics or performance measures for applicable models

 

APA formatting for the reference list, and proper grammar, punctuation, and form are required. APA help is available here.
