In your opinion, should the Sorbane-Oxley Act remain in force or should it be abolished? Explain your position.

The Sarbanes-Oxley Act (SOX) was signed into law on July 30, 2002 in response to corporate scandals such as WorldCom and Enron.

Now all companies are required to file periodic reports with the Securities and Exchange Commission (SEC) with new requirements for reporting of corporate obligations. Non-compliance to these regulatory requirements comes with significant penalties.

Debates have continued since 2007 over the perceived benefits and costs of SOX. Opponents of the bill have claimed that it has reduced America's international competitive edge against foreign financial service providers because it has introduced an overly complex regulatory environment into U.S.financial markets.

Proponents of the measure said that SOX has been a "godsend" for improving the confidence of fund managers and other investors with regard to the veracity of corporate financial statements.

What might be a good statement to describe HHCS mission? In other words, create a mission statement for HHCS.

A study of smoking status and the risk for recurrent coronary events after myocardial infarction (Rea et al, 2002) had the following results: a) 433 out of 2619 patients who survived to discharge had a recurrent coronary event within 3 years; b) With nonsmokers as the reference group, the relative risk for recurrent coronary events of persons who stopped smoking before their heart attack was 1.17 (95% CI, 0.93 to 1.43); for those who continued to smoke after their heart attack their relative risk of recurrent coronary events was 1.51 (95% CI, 1.10 to 2.07) c) For those who quit after their heart attack, their risk declined gradually over the three year follow up to that of nonsmokers. 11.

Between 20 and 25 violent acts are portrayed per hour on children’s TV. A study by Johnson et al (2002) looked for links between TV viewing and aggression by following the TV viewing habits of children 1-10 years old. Of these, 88 watched < 1 hr TV per day, 386 watched 1-3 hrs and 233 watched > 3 hrs. Eight years later, researchers looked to see if any of the children had records of aggressive assaults on other people. The numbers of children with aggressive assaults were 5, 87 and 67 for each TV category, respectively. The remaining children were not aggressive.

Question 1: Create a contingency table of the results from the study. Carry out an appropriate statistical test to determine whether TV viewing is associated with future violence. What is the conclusion from your test?

Question 2: Do the results of the study prove that TV watching behavior causes increased aggression in children? Why?

In some of the recent corporate scandals, senior executives “doctored the books” and misrepresented the corporate financial status of the company. In others, transactions were created to and from inert or false companies to enhance the bottom line. All of these actions required some intervention and dependence on current or new IT systems. As a result the Federal Government passed the SOX regulations in 2002-2003 and the Dodd-Frank Financial Reform law in 2010.
