According to the EPA’s prospective analysis of the 1990 to 2010 period, total social benefits (TSB) associated with the CAAA of 1990 are estimated at $690 billion and the comparable total social cost (TSC) estimates are $180 billion (both in $1990).

a. Explain why these data do not communicate whether the regulations outlined by the CAAA of 1990 are efficient.

b. Using three separately labeled graphs of conventionally-shaped TSB and TSC functions show that these values indicate that the regulations outlined in the CAAA of 1990 are (i) efficient; (ii) too lenient; and (iii) too stringent.

According to Stanovich (2010), case studies and testimonials stand as isolated phenomena. They lack the comparative information necessary to prove that a particular theory or therapy is superior. However, it is wrong to cite a testimonial or a case study as a support for a particular theory or therapy. What might have happened in science if a psychologist or an individual cite a testimonial or a case study as a support for a particular theory or therapy? why, why not?

1. Summarize the case

At an employer's automotive component manufacturing facility, manufacturing operations make extensive use of robots located within fenced cages. At one location, suspension parts are transferred by rotating tables from station to station while greasing and other operations are performed on the parts by robots. If necessary, employees can gain access to the robots by entering the cages through electrically interlocked gates. When the gates are opened, the multiple energy sources that power the robots, rotating tables, and related machinery are turned off but are not deenergized or locked out. An employee who is inside a cage when a robot is activated could be struck by the robot arm or other machine parts and seriously injured.

An injury occurred when an employee, consistent with the employer's practices, entered the robot cage without deenergizing or locking out any equipment. The employee was attempting to unjam a robot arm. In freeing the arm, the employee tripped an electric eye, causing the robot arm to cycle. The employee's arm was struck by the robot and injected with grease. The employer contends that lockout procedures were not necessary because once the gate is opened, movement of the robot arm is impossible, and a maintenance worker inside the cage would have ample warning – by the closing of the interlocked gate – before the machinery started up, to avoid injury. According to the employer, once the interlocked gate is opened, it must first be closed and a number of buttons must be pushed before any machine movement can occur. The startup procedure would take some time and the person inside the robot area would be aware of the closing of the gate and the presence of another worker at the nearby control panel.

Please solve all bits. Otherwise i will thumbs down...sorry

A 200.0-liter water tank can withstand pressures up to 20.0 bar absolute before rupturing. At a
particular time the tank contains 165.0 kg of liquid water. the fill and exit valves are closed, and the
absolute pressure in the vapor head space above the liquid (which may be assumed to contain only
water vapor) is 3.a bar. A plant technician turns on the tank heater, intending to raise the water
temperature to 155°C, but is called away and forgets to return and shut off the heater. Let tl be the
instant the heater is turned on and t2 the moment before the tank ruptures. Use the steam tables for
the following calculations.
(a) Determine the water temperature. the liquid and head-space volumes (L), and the mass of water
vapor in the head space (kg) at time t1.
(b) Determine the water temperature, the liquid and head-space volumes (L), and the mass of water
vapor (g) that evaporates between tl and t2. (Hint: Make use of the fact that the total mass of
water in the tank and the total tank volume both remain constant between tl and t2')
(c) Calculate the amount of heat (kJ) transferred to the tank contents between tl and t2. Give two
reasons why the actual heat input to the tank must have been greater than the calculated value.
(d) List three different factors responsible for the increase in pressure resulting from the transfer
of heat to the tank. (Hint: One has to do with the effect of temperature on the density of liquid
water.)
(e) List ways in which this accident could have been avoided.

A Turning Point for David

2018 ABC Student Writing Contest Prompt

Case submitted by Andy Spackman, Brigham Young University

You close your office door and take a few minutes to breathe. Your meeting with David could have been a disaster in a dozen different ways. Instead, it actually went well. By emphasizing your shared passion for innovation you managed to establish a safe foundation for an open discussion. You expressed your concerns about David’s lack of reliability and together you outlined a plan for improvement. Although he wasn’t happy, David didn’t dissolve into one of his famous fits, and he committed to making the changes you agreed on.

However, you know your work is only half done. It was important to talk to David face-to-face, but now you have to document your conversation. Putting it in writing will solidify his commitment and allow for real consequences. Before outlining your message, you review your notes about David’s performance and make some new ones regarding today’s discussion.

David Federro
Two years ago you arrived at PrinTech as the new Vendor Integration Manager, and it wasn’t long before you realized one of your programmers, David Federro, was going to be a problem. David is brilliant. In fact, your own reputation as a rising star in PrinTech’s management is partly due to the APIs David has created to enable client web services.
Unfortunately, David is far less reliable than brilliant. He misses deadlines, ignores phone calls, and no one knows when he will be in his office. You’ve found it hard to address these issues because David’s pattern of behavior was well-established before you joined the company, and previous managers gave him free rein as long as he kept producing high-quality work.
Several team members have told you they find David difficult to work with, describing him as surly and nonresponsive, and complaining that his portions of projects are consistently behind schedule. You suspect another programmer’s recent departure was partly due to the way David left her hanging on a project and publicly demeaned her when she confronted him. On the other hand, the quality of David’s work is universally recognized. Some key clients have asked that their projects be given to him, even though you occasionally have to make excuses for his failing to meet deadlines.
David’s performance over the past few months has been particularly problematic. He missed a week of work and was out of contact. He later claimed to be working from home but had not obtained prior permission. On another occasion, you had to reassign an important client’s project to a different programmer when it became clear David would not complete the job. You’ve come to the conclusion that David is on a trajectory where the problems he creates will soon outweigh the value he brings.
Your boss, Amanda Paik, agrees but has made it clear she hopes you can keep such a talented employee.
The Plan for Improvement
When you spoke David explained that he enjoys his job overall, and takes pride in his reputation for making innovative contributions. However, when he feels uninspired by a project he has a hard time focusing on his work. He revealed that during his personal time he is working on an open source project to help refugee relocation agencies manage their services, and he is clearly passionate about this volunteer work. He said he dislikes collaborating because other team members “hold him back” with their “lack of imagination” and “skill deficiencies.” He also explained that the reason why he recently missed a week of work is that a childhood friend passed away.
You and David agreed that his ability to contribute to the company’s success hinges on whether teammates and clients can rely on him. Together you made the following commitments: ? David will meet deadlines and understands that failure to do so will leave him ineligible to receive the usual year-end bonus and may result in termination. ? David will behave collegially with teammates and be more responsive to phone calls and emails. ? David will ask permission before working from home and will promptly inform you of illness or emergency. ? You will schedule regular check-ins with David to monitor progress toward project deadlines. ? You will include David in project origination meetings, allowing him to influence the scope of projects and suggest alternative, more innovative solutions.
Remember that the wording of your notes does not necessarily mirror the wording of your conversation with David.

Assignment

Write an email to David summarizing key points of your conversation, including your concerns and the areas of improvement you and David agreed to. Your email should be clear, concise, well-organized, and well-designed. Your purpose is to ensure David understands expectations and to establish his accountability for improvement. You want this to be a meaningful turning point for David, so your email must also preserve a positive relationship.

Address the email to David Federro and CC the Vice-President of Client Services, Amanda Paik, and the Director of Human Resources, Neil Woerkom.
