I. Answer part A,B, C and D.

1a)

Count the number of times a given char occurs in a given range of a String parameter (i.e. starting at a given start index, and up to but not including and end index). If end is greater than the length of the String, then the method should stop looking at the end of the String.

countCharsInRange("java", "v", 1, 2) → 0
countCharsInRange("java", "v", 0, 2) → 0
countCharsInRange("java", "v", 0, 3) → 1

1b)

Return a new String that removes all copies of the given char ch from the given String

removeChar("dog", "o") → "dg"
removeChar("cat", "o") → "cat"
removeChar("aaa", "a") → ""

1c)

Return the number of times the letter 'a' is directly followed by the letter 'b' in the given String.

countAB("abc") → 1
countAB("wxyz") → 0
countAB("bcaca") → 0

1d)

Return a new String that is a copy of the given String with each character copied the given number of times. Assume that n is 0 or more.

eachCharNTimes("abc", 2) → "aabbcc"
eachCharNTimes("xyz", 3) → "xxxyyyzzz"
eachCharNTimes("a", 5) → "aaaaa"

Memory is the ability to store and retrieve information over time and is the result of the processes of encoding, storage, and retrieval. Memory plays a role in the most mundane activities, such as remembering where the car keys are, and the most elaborate of processes, such as forming a personal identity or establishing neural connections. Memories are not passive recordings of the world, but instead result from combining incoming information with previous experiences. Encoding is the process of linking new and old information together and turning that information into lasting memories. Memory is influenced by the type of encoding we perform regardless of whether we consciously intend to remember an event, fact, or experience. Semantic encoding (actively linking incoming information to existing associations and knowledge), visual imagery encoding (converting incoming information into mental pictures), and organizational encoding (noticing relationships among items to be encoded) all enhance memory. Different regions within the frontal lobes play important roles in semantic encoding and organizational encoding, whereas the occipital lobes are important for visual imagery encoding.

A casual glance at the world reveals that an inordinate number of things seem to conform to the 7 ± 2 rule made famous by George Miller in 1956, who found that the capacity of short-term memory was 7, plus or minus 2, chunks of information. The creations of ZIP codes, telephone numbers (with or without area code), Social Security numbers, and 5-, 7-, or 9-point Likert scales all suggest that people have difficulty keeping track of information that goes beyond 9 or so chunks, or discriminations. Furthermore, in 1961 anthropologist Anthony Wallace studied vastly different cultures ranging enormously in size and still found a striking similarity: In each case the number of dimensions needed to account for kinship terms (“aunt,” “cousin,” “father”) was relatively invariant, ranging from about 5 to 9. It seemed to Wallace that the development of language, even across cultures, obeyed the constraint found in human cognitive processing.

Looking at your current world, generate examples of people, events, or things in the word that can be packaged with this 7 (+ or – 2) range. Here are some examples to give you some ideas: lucky number 7; 7 days of the week; 7 dwarfs.

Do your examples of “set of seven” represent simple numerology and coincidence or were the examples designed specifically to better accommodate the human memory?

Prompt #1 About one baby out of every 600 born in the U.S. has Down’s syndrome. Many of these children are born with fatal physical conditions that can cause quite a bit of pain and suffering. For instance, a baby with Down’s syndrome could be born with part of their vital organs missing, intestines might be blocked, and their heart might not pump properly. Surgery is often required for these infants to survive beyond the first few days of life.

Parents must decide whether to allow surgery to save the child, who may end up requiring costly long-term care and services for life or withholding permission thus causing the child to die.

*Is it immoral for the parents to withhold surgery?

*Likewise, is it immoral for the parents to allow the surgery?

*Is the assumption that parents will act in the best interest of their child justified?

*Morally speaking, would the physician deciding not to operate be tantamount to murder?

*Ethicist James Rachels (1975) uses the Baby Does case to illustrate how passive euthanasia can sometimes cause more suffering than active euthanasia. If it is morally permissible for parents to allow their infants to die, should active euthanasia be used instead?

*Considering the moral issues related to quality and sanctity of life, the principle of do no harm, and palliative care, are there ever any cases when euthanasia of an infant is morally justified? (USLOs 8.1, 8.3)

Compact fluorescent bulbs are much more efficient at producing light than are ordinary incandescent bulbs. They initially cost much more, but last far longer and use much less electricity. According to one study of these bulbs, a compact bulb that produces as much light as a 100 Wincandescent bulb uses only 23.0 W of power. The compact bulb lasts 1.00×10⁴ hours, on the average, and costs $ 12.0 , whereas the incandescent bulb costs only 76.0 ¢, but lasts just 750 hours. The study assumed that electricity cost 9.00 ¢ per kWh and that the bulbs were on for 4.0 h per day.

(A) What is the total cost (including the price of the bulbs) to run incandescent bulbs for 3.0 years?

(B) What is the total cost (including the price of the bulbs) to run compact fluorescent bulbs for 3.0 years?

(C) How much do you save over 3.0 years if you use a compact fluorescent bulb instead of an incandescent bulb?

(D) What is the resistance of a "100 W" fluorescent bulb? (Remember, it actually uses only 23 W of power and operates across 120 V.)

Demand averages 20,002 units per year and operates 365 days per year. Holding cost= $5 per unit per year while the ordering cost is $100 per order. Company is currently using a periodic (P) inventory system, holding 1000 units in safety stock to cover demand uncertainty and placing orders for every 73 days. The company is investigating the possibility of using a continuous review (Q) inventory system with holding 15 units in safety stock to cover demand uncertainty. Use the info to answer the next questions

Suppose a Q system is used with a lot size of 200 (not the EOQ) Assume the safety stock is 15 units.

A)What is the reorder point?

B) Under the company's current P system (from the begging) how much will annual holding costs be? Assume 1000 units in safety stock

C) Annual ordering costs?

D) What is the Target level for this P system?

Imagine you are tasked with conducting a counseling intake interview with a 19 year old college student who is feeling sad, unmotivated, and worried about his grades. It is the student’s first semester at school, and he is finding that he has gone from being an A student in high school to a B- student in college. He has also moved 500 miles away from his hometown to attend school.

a number of counseling approaches (cognitive, humanistic, psychodynamic, and behavioral), that can be used to guide and understand an interview.

Which approach would you use to guide this intake interview? Explain why you think this approach is a good choice for this particular interview also, develop at least 5 questions for your interview and explain how the questions fit with the approach you chose.

In chickens, comp shape is determined by alleles at two loci (R, r and P, p). A walnut comb is produced when at least one dominant allele R is present at one locus, at least one dominant P allele is present at the second locus (i.e. genotype R_P_). A rose comb is produced when at least one dominant allele is present at the first locus and two recessive alleles are present at the second locus (genotype R_pp). A pea comb is produced when two recessive alleles are present at the first locus, and at least one dominant allele is present at the second (genotype rr P_). If two recessive alleles are present at the first and the second locus (rrpp), a single comb is produced. Progeny with what types of combs and in what proportions will result from the following crosses?

a. RR PP x rr pp

b. Rr Pp x rr pp

c. Rr Pp x Rr Pp

d. Rr pp x Rr pp

e. Rr pp x rr Pp

f. Rr pp x rr pp
