Globalization: Exam

  • There are 5 short-answer questions (worth 10 points each) and 1 longer essay question (worth 50 points) on this exam.
  • A high scoring answer for the short answer questions will consist of at least 4-5 sentences and demonstrate wide understanding of course material.

1. Snarr & Canfield describe four different scenarios on the future of global governance (world government, regionalism, decentralization/self-reliance, status quo). Which of these do you feel is the most desirable and why?

2. How effective do you anticipate the 2015 Paris Agreement (and other future international climate agreements) will be? What international developments might limit its effectiveness?

3. It is argued that increasing threats from climate change means that low-income countries (LICs) can no longer be allowed to develop via fossil fuels in the way the high-income countries (HICs) have. Consequently, LICs argue that HICs are hypocrites and that they should be allowed to develop as they see fit. Who do you think is right?

4. How has the ‘liberal world order’ as described in the Pei and Micklethwait & Woolridge articles been unsettled by China’s rise?

5. With regards to global public health, preventative measures and the strengthening of health systems (vertical approaches) seem to take a backseat compared to emphasis on big, singular problems such as COVID or Ebola (horizontal approaches). Why do you think this?

Question 1 1 pts
ESSAY QUESTION:
Imagine you are a government policymaker for a low-income country (LIC) and your elected president comes to you for advice. The president knows you are familiar with globalization wants to know what sort of guidance you can provide for the country’s economic and political development. What advice would you give to the president of your country? (This is an imaginary country and you are free to make assumptions about your country’s resources and geographic location).

Your answer should discuss concepts, events and processes discussed in lecture and the readings. A strong essay will directly answer the question and demonstrate a deep and wide knowledge of the course material.

Based on the pdfs, provide a brief background of the company and provide TRENDS that actually exist that would cause a question or concern.

Question 2 (5x5pts) Basic calculations of rates

  1. [11.24 – Dimensional analysis] Concentrations in atmospheric chemistry are most often reported in molecule/cm3. As a result, second-order rate constants used in modeling atmospheric chemistry are commonly reported in units of cm3 molecule–1 s–1. Convert the rate constants 3.5 x 10-14 cm3 molecule–1 s–1 to L mol–1 s–1. Is that unit conversion the same for all chemical compounds? What would you need to convert to L g-1 s-1?

 

 

  1. [11.27 – Dimensional analysis] Show that if the units of rate are mol L−1 s−1, then the units of the rate constant for the following second-order reaction are L mol−1 s−1:

 

H2(g) + Br2(g) à  2 HBr            rate = k [H2][Br2]

 

  1. [11.25 – Rate laws] For each of the rate laws below, what is the order of the reaction with respect to the hypothetical substances X, Y, and Z? What is the overall order?

Question 4: Using the equation for first order kinetics – exponents/logarithms practice (15pts)

Consider dieldrin, a pesticide in the category of organochlorines. It has a half-life of 934 days. After calculating its reaction rate constant, assuming first order kinetics, calculate the following:

  1. For an initial concentration of 12 ppm in water, calculate the concentration after 10 hours, after 1 month, and after 1 year.
  2. Considering a water that has 40 ppb of dieldrin in it, how long will it take for the concentration to drop below 5 ppb.
  3. How long will it take for the concentration to reach 10% of its initial value, regardless of the starting concentration.

Brookson v. Carter, Defendant’s Worksheet

DEFENDANT’S WORKSHEET FOR TRIAL

Fred Brookson, a lifelong resident of Klamath Falls, Oregon, has hired your firm to file suit against Wendell Carter for injuries sustained as a result of an incident that occurred in southern Oregon. About three months ago, Brookson and his wife, Ellen, from whom he is now separated, participated in a demonstration concerning recent acts of violence against doctors practicing in a local abortion clinic. The demonstration occurred on a wharf extending into the Coos River. A group of people, including Wendell Carter, gathered around the demonstrators and began to heckle them. The two groups exchanged remarks and eventually, the hecklers threw rocks and bottles at the demonstrators. When Carter threw a rock that struck and injured Ellen, Fred became angry and approached Carter. Carter said he regretted injuring Ellen because he had been aiming at Fred. The two men exchanged heated remarks. Then, without any provocation, Carter pulled out a knife, screamed, and lunged at Brookson, intending to stab him. As Brookson jumped back to avoid being injured, he almost bumped into an unidentified demonstrator. The demonstrator, who apparently thought he was being attacked, struck Brookson several times and seriously injured him. Both Brooksons required hospital treatment. Fred Brookson ‘s medical expenses exceeded $75,000; his estranged wife’s expenses were approximately $2,000. Both have lost weight, exhibit chronic anxiety, and have periods of severe insomnia.

Carter grew up in California but has spent the last three years attending college and living with his brother in Oregon. Plaintiff’s attorney believes it best to bring this action in federal district court.

Jansen v. McLeavy (1987)

Mabel Jansen brought suit against the defendant for negligence and intentional infliction of emotional distress after the defendant’s car ran a stop sign and killed her young son. She witnessed the accident from her front yard. The jury awarded her $175,000 for the defendant’s negligence in causing the death of her son and $250,000 for intentional infliction of emotional distress. The defendant appeals only the latter award, and we reverse.

For intentional infliction of mental distress, proof of four elements is required to establish the cause of action: (1) the conduct of the defendant must be intentional toward the plaintiff; (2) the conduct must be extreme and outrageous; (3) there must be a causal connection between the defendant’s conduct and the plaintiff’s mental distress; and (4) the plaintiff’s mental distress must be extreme and severe. On this appeal, the defendant vigorously argues that the first element has not been met. The tort of intentional infliction of emotional distress requires some evidence that the defendant intended to inflict the emotional distress on the plaintiff. Although Jansen’s mental distress was great, the driver did not intend to cause that distress. While some jurisdictions have allowed recovery in similar circumstances on a theory that the defendant’s conduct made it probable that mental suffering would result, we will continue to require intentional infliction in this state.

Powers v. Locke (1989)

While plaintiff Anthony Powers and defendant James Locke were waiting in line to board a school bus, Locke shoved Powers in an effort to take his place in line. Powers fell through a glass door and suffered multiple injuries. Powers sued Locke for battery. The trial court entered a directed verdict in favor of Powers.

A defendant commits battery when he acts intending to cause a harmful or offensive contact with the plaintiff or a third person, and thereby causes a harmful or offensive contact with the plaintiff. Because battery is intended to protect a person’s body from intentional and unwanted contact, its protection extends to anything so closely connected with the person’s body as to be regarded a part of it, but it does not extend to contact that is legally consented to or otherwise privileged. One who commits battery is liable for no more than nominal damages unless the person contacted proves actual harm.

Locke’s argument that the evidence does not support a finding that he intended to cause injury to Powers is without merit. The tort of battery requires only that the defendant intend the contact that caused the harm, not the harm itself. Here, the evidence is uncontroverted that Locke intended to shove Powers. Locke also argues that Powers consented to the battery by agreeing to engage in a “shoving match” with Locke. Because the evidence presented at trial is conflicting on this issue, a directed verdict was improper. Reversed and remanded.

Logistics Management

Critical Thinking

The global marketplace has witnessed increased pressure from customers and competitors in manufacturing as well as the service sector (Basu, 2001; George, 2002). Due to the rapidly changing global marketplace, only those companies will be able to survive that will deliver products of good quality at a cheaper rate to achieve their goal companies try to improve performance by focusing on cost-cutting, increasing productivity levels, and quality and guaranteeing deliveries in order to satisfy customers (Raouf, 1994).

Increased global competition leads the industry to increase efficiency by means of economies of scale and internal specialization so as to meet market conditions in terms of flexibility, delivery performance and quality (Yamashina, 1995). The changes in the present competitive business environment are characterized by profound competition on the supply side and keen indecisive in customer requirements on the demand side. These changes have left their distinctive marks on the different aspect of the manufacturing organizations (Gomes et al., 2006). With this increasingly global economy, cost-effective manufacturing has become a requirement to remain competitive.

To meet all the challenges organizations, try to introduce different manufacturing and supply techniques. Management of organizations devotes their efforts to reducing manufacturing costs and improving the quality of the product. To achieve this goal, different manufacturing and supply techniques have been employed. The last quarter of the 20th century witnessed the adoption of world-class, lean and integrated manufacturing strategies that have drastically changed the way manufacturing firms leads to improvement of manufacturing performance (Fullerton and McWatters, 2002).
