(TCO 5) Jane’s parents have created a savings account to save for her college education. If they invest $1,000 a year at 6% interest beginning on her first birthday, how much will be in the account when she reaches age 18?

(TCO 5) You own a contract that promises an annuity cash flow of $250 year-end cash flows for each of the next 3 years. (Note: The first cash flow is exactly 1 year from today). At an interest rate of 8%, what is the present value of this contract?

(TCO 5) You have been accepted into a prestigious private university in Illinois for your doctoral program. Congratulations! Since no one from this school has ever graduated in only 4 years, you anticipate that you will need to make 11 semi-annual tuition payments of $35,000 each with the first cash flow 6 months from today. If you choose to discount these cash flows at an annual rate of 8%, what is the present value cost of tuition to attend your university of choice?

(TCO 5) You are about to purchase a new car from a dealer who has a new and unusual payment plan. You have the choice to pay $29,000 cash today or $32,000 in 4 years.

Sage is a 26-year-old doctoral candidate in English literature at the local university. She is in good standing in her program and has plans to enter the job market in the fall. In your intake, she tells you she thinks she is “fat” and has been self-conscious about her body since the sixth grade, at which time she began menstruating and developing breasts earlier than the other girls in her class. She was teased for needing a bra and remembers feeling “chubby, too big, and just wanting to be small like [her] younger sister.” She started dieting in the seventh grade, following strict rules for weeks (e.g., she recalls the grapefruit only diet), then transitioning into what she called “bad” weeks. During these times, she would stock up on candy bars and other snack foods and eat them, often in her bedroom late at night. Her parents became concerned and tried to strictly limit her dieting. This led to eating “normal” during the day and binging on those candy bars she kept hidden in her bedroom at night if she felt sad, scared, or mad. She grew into a habit of eating to feel better – relief that was only temporary, as she would feel ashamed about what she had done and resolve to not do it again. In college, her pattern of emotional eating continued, which felt more distressing to her because of the pressure to look “as pretty and thin as the other girls.” In spring of her freshman year she experimented with throwing up after the late-night eating and found that, at least in the minutes that followed, she felt like she had much more control and believed this would help her to prevent the weight gain she so dreaded. She fell into a vicious cycle of late-night binges (typically consuming about 7 candy bars in 15 minutes, during which times Sage described feeling very out of control) followed by making herself throw up. In college, she engaged in these binge-purge episodes about 6 nights/week. At present, she is having a harder time hiding the episodes because she lives with her boyfriend; she estimates that they occur about 4 nights per week. The times when she feels the most compelled to binge and purge are when she has a major presentation coming up in her doctoral program and when she gets in a fight with her boyfriend. Her BMI is in the normal range, but she says she needs to lose weight. She wants to stop binging and purging because she does not want her boyfriend to find out, but she is also afraid that if she stops, she will gain weight.

Child abuse and maltreatment is not limited to a particular age—it can occur in the infant, toddler, preschool, and school-age years. Choose one of the four age groups and outline the types of abuse most commonly seen among children of that age. Describe warning signs and physical and emotional assessment findings the nurse may see that could indicate child abuse. Discuss cultural variations of health practices that can be misidentified as child abuse. Describe the reporting mechanism in your state and nurse responsibilities related to the reporting of suspected child abuse.

1. The average teenager gets 7 hours of physical activity in a given week, with a standard deviation of 0.5. Michelle Obama’s Lets Move! Initiative encourages schools to add more physical activity into the school day. They add additional physical education classes and extra recess activities. 25 students are selected at random and report how many hours of physical activity they had in the last week. The mean is 7.18.

In the novel Never Let Me Go by Kazuo Ishiguro, children are raised in a boarding school to become organ donors for society. The children eventually find out they are genetic clones created for the expressed purpose of providing another individual backup organs to prolong that individual’s life. Are cloned life forms the same as the original of the copy? Do they have the same rights and privileges of individuality if they are genetically identical to someone else? How might our own history with copied things influence our perceptions and interactions with clones?

In that law, we see increasing returns at the start of production, production then exhibits diminishing returns until it peaks, and then will exhibit negative returns if we attempt to push beyond that.

Now, think about your work day - it could be a work day at your place of employment or a work day of school activities or a workday at home if you are a homemaker. Provide two examples of how your work day exhibits increasing returns, diminishing returns and then negative returns. Be sure to explain how all these different types of returns would happen.

The Indian Act was passed in 1876 with the specific purpose of creating a “framework of regulations” to control almost all aspects of native life. The ultimate goal of the Act was the assimilation of the all Aboriginal people into the Canadian mainstream population.
