Describe the 4 phases of demographic transition.  2 part question

For each phase, compare crude birth rates (CBR) to crude death rates (CDR), and state whether the population is stable, growing, or declining in each. 

Explain factors that contribute to changes in CBR and CDR between phases.

Methods

Participants

Participants (N = 8,997) were undergraduate students at 20 2- and 4-year college and university campuses in Minnesota who completed the 2015 College Student Health Survey.¹⁷ Data were collected online between February 16, 2015 and March 27, 2015. Most (68%) participants were female. Participants identified as White (81.6%), Asian (8.6%), Black or African American (6.1%), American Indian or Alaska Native (2.1%), Native Hawaiian or other Pacific Islander (0.4%), other races (1.9%), and prefer not to answer (2.9%). Percentages did not add to 100% because respondents could indicate more than one race. The median age of the sample was 21 years old (range =18–74). Most (73%) of the sample was enrolled in 4-year colleges and universities. Almost half (47%) were first-generation college students (ie, neither parent had a 4-year college degree). The sample included participants who identified as heterosexual (89%), bisexual (4%), g** or lesbian (2%), or other (4%). The study was approved by the institutional review board (IRB) of the university that sent the survey (Study # 0012S75881). Other schools signed an agreement with that university or sought approval from their own IRB. All study procedures were carried out in accordance with the latest version of the Declaration of Helsinki. Students provided consent on the online survey.

Measures

Factors perceived to affect academic performance

Factors that were perceived to affect college academic performance were assessed by a measure that presented students with a list of 20 factors, including stress.¹⁷Students rated each factor in terms of whether they had experienced it and, if so, whether or not it had affected their academic performance during the past 12 months (1 = I do not have this issue/not applicable; 2 = I have this issue, my academics have not been affected; 3 = I have this issue, my academics have been affected). The similar question on the NCHA survey assessed how academics were affected (eg, scored lower on a test or project) in separate responses, graded for severity of the academic impairment, whereas this survey had a single response option for academics being affected by the factor.

Stress

Stress was measured on a 10-point scale on which students rated their average level of stress over the past 30 days (1 = Not stressed at all to 10 = Very stressed). The construct validity of scores on this measure was supported by the finding that students who scored higher on this measure also reported more days with poor mental health (including stress, depression, and problems with emotions) in the past month (r = .49, p < .001).

Coping self-efficacy

Coping self-efficacy was measured on a 10-point scale on which students rated their ability to manage their stress over the past 30 days (1 = Ineffective to 10 = Very effective). The construct validity of scores on this measure was supported by a negative correlation between coping self-efficacy and stress (r = −.47, p < .001).

Resilience

The Brief Resilience Scale (BRS)¹⁸ is a 6-item measure of resilience, defined as the ability to “bounce back or recover from stress” (p. 194). Students rated each item (eg, “It does not take me a long time to recover from a stressful event”) on a 5-point scale (1 = Strongly Disagree to 5 = Strongly Agree). Higher scores indicate greater resilience. Smith et al reported a test-retest reliability coefficient of .69 in a sample of undergraduate students over a one-month period and Cronbach’s alphas ranging from .84 to .87. In the current sample, α was .88.

Social support

Students rated the supportiveness of their family, friends, college/university faculty, and college/university staff on four separate items. Each item was rated on a 10-point scale (1 = Very unsupportive to 10 = Very supportive). To create an overall measure of social support, scores on these four items were averaged (α = .84).

Academic performance

Participants reported their cumulative grade point average (GPA) to two decimal places (M = 3.35, SD = 0.49). The correlation between self-reported college GPA and data from student records was r = .90 in a meta-analysis.¹⁹

^{Q. Research Methods}

Discuss the methods the researchers used for: selecting study participants and collecting and analysing data.

What were the strengths and weaknesses of the methods used?

My question:

Explaining 2 different unethical issues in Singapore that can happen in 4 departments. Explaining one strategy the company can develop to minimise or eliminate those unethical issues (1 for each, viable, logical solutions). How the company we found shows CSR and how another company don't show it. - Reason to let them show CSR (how to persuade them?)

in a test tube containing 2 mL of 2.4*10^-4 M KSCN, and 23 mL of 0.10 M Fe(NO3)3, what are the number of moles of SCN^-, the number of moles of FeSCN^2+, and the concentration of FeSCN^2+ in mol/L?

Two balls are chosen randomly from a box containing 8 white, 4 red, and 2 green balls to see if you will win any money. Suppose that you win $2 for each red ball selected, you lose $1 for each blue ball selected, and you get nothing for each green ball selected. What is the probability that you will not lose any money?

Critical Thinking Case 2
Reconciling the Campbells' Checking Account

Caleb and Eva Campbell are college students who opened their first joint checking account at the American Bank on September 14, 2015. They've just received their first bank statement for the period ending October 5, 2015. The statement and checkbook ledger are shown in the table below.

From this information, prepare a bank reconciliation for the Campbells as of October 5, 2015, using a form like the one in Worksheet 4.1. Enter all answers as positive values. Leave no cell blank, enter "0" wherever required. Round the answers to the nearest cent. Enter your answers in the given order of Check numbers.

Given the new checkbook balance calculated under Question 1, determine the net adjustment, if any, adjustments will the Campbells need to make in their checkbook ledger. Enter the answers as positive value. Round the answer to the nearest cent.
$  

If the Campbells earned interest on their idle balances because the account is a money market deposit account, what impact would this have on the reconciliation process?

The effect of the interest earnings would have been a(n) in both bank and checkbook balances.

Explain.
