...QUESTION #1: Incident 1 – “An Ethical Flaw” (pg. 40) Question 2-11: From an ethical standpoint, how would you evaluate the merits of Mr. Garbo’s employing Amber? Discuss. Answer 2-11: I definitely think that the decision to hire Amber was extremely unethical. I don’t think that it was right for Mr. Garbo to pressure Mr. Davis into hiring his daughter when she didn’t show the motivation to attempt to find a job on her own. I understand that sometimes having “connections” is helpful, but when you don’t show that you’re worthy of the positon, you shouldn’t hire someone in just because you think that it will help you out professionally in the future. If Amber had shown that she was competent, able, eager and mature then it would be obvious that she may be suitable for the position. However, Amber did not possess these characteristics so Mr. Garbo’s decision was based solely on his business relationship with Mr. Davis. It is usually a bad idea to employ a friend or coworker’s son or daughter due to this fact. Just because they are a good worker, doesn’t mean that their kids will be too. (pg. 27) Question 2-12: Now that she is employed, what course would you follow to address her on-the-job behavior? Answer 2-12: I definitely think that Mr. Garbo should have a serious talk with Amber and try to help and encourage her to become a better and more productive member of their team. He should also let her know that is she doesn’t become more productive then she...

It can be the result of a condition such as cerebral palsy or strokes, but there is often no known cause. The symptoms of a seizure can range from simple staring spells to convulsions and loss of consciousness. The seizures can also vary in frequency, although in order to be diagnosed with epilepsy you must have had two unprovoked seizures. Epilepsy is primarily treated with medications, which are successful in reducing the frequency and severity of seizures in more than half of epilepsy patients. However, even mild seizures can be dangerous if they happen at certain times, such as when you’re driving or swimming, and could limit your ability to perform some work activities.

...HR 434 Take Home Exam #1 Due Sunday night of week #4 Name:__Jessica Washington_______________ 1. (10 points) What changes are occurring in the workforce relative to the kinds of work employees are performing? Before there was computers to do all the work in manufacturing companies, employers were spending up to 40 cents on the dollar for base pay and compensation packages for employees. Due to all the computer being used today this number has gone down along with the manufacturing employment. Today, less than 20 percent of the workforce is involved in manufacturing. More people are now working in service-related industries and jobs. More than 70 percent of all workers perform what is known as service jobs. Most service-sector organizations are heavily labor concentrated, and it is not unusual for service-related companies to spend 40 cents and sometimes as high as 80 cents of each revenue dollar for employee compensation costs. As you can see service-related companies spend much more in compensation costs than what was being spent in the manufacturing economy. Due to the work being heavily labor concentrated it is very necessary for them to compensate them accordingly. 2.

Pa460 Exam 1

...PA 460 Professor Wilkins Exam 1 Part 1: Terms Efficiency: Efficiency is a term that refers to the measuring of how well a public policy really works. Efficiency takes into consideration several factors such as cost, results, impact, feedback and puts it all together to measure the overall success of a public policy under an efficient point of view. While it is true that efficiency more often than not is represented by a ratio between results and costs, it could be argued that other factors play a role in it. Ultimately, high efficiency is very hard to achieve even when measuring some of the best policies, but what is even harder is determining a cost for a specific policy. Therefore, efficiency is often measured by analyzing procedural efficiency instead which compares what is produced to its cost. Implementation: Implementation is a term that refers to putting public policies into effect in order to achieve goals set for those policies. However, in reality implementation is hard to achieve as there are so many different ways to stop a public policy from being adopted or carried out. In fact, one thing is to have a public policy approved by law, but even then its implementation is not guaranteed which means administrators who have their public policies implemented should consider themselves lucky. An example of implementation would be the actual actions required to get a public policy started, whatever those may be. Coming up with public programs is one thing, but its implementation...
