Chapter 2 – Marketing Ethics Marketing to children has always been controversial. Indeed, in the 1970’s, the FTC considered prohibiting all advertising to children. The federal government once again is setting its sights on marketing aimed at children. With the US child obesity rate and predicated to exceed 20% in just a few years, regulators are pressuring marketers in general, and food marketers in particular, to curb their marketing practices to children. In 2008, the FTC delivered an analysis to Congress of 44 companies’ $1.6 billion food and beverage marketing activities targeting children. A provision in the 2009 omnibus spending bill signed into law by President Obama created the Interagency Working Group on Food Marketing to Children. This group will present recommendations to Congress in 2010 regarding marketing to children and aged 17 and younger. With children and teens spending billions of their own dollars and influencing much more of their parents spending, this is an important market segment to marketers.

1. Studies report that children view more than 20 food ads each day, of which over 90% promote high fat, high sugar products. The marketing concept focuses on satisfying consumer’ needs and wants, but are marketers crossing the line when they cater to younger consumers’ wants for products that may counter parental wishes or that may be unhealthy?

2. What actions are marketers taking to market their products to this market segment more ethically? Discuss industry initiatives that help marketers market to children more responsibly.

In a paragraph, relate the following terms:  Metabolism, anabolism, catabolism, hydrolysis, condensation, endergonic, exergonic.  

Relate means group those terms together that belong together. For example, anabolism means to build up larger molecules. What process do we use to build up larger molecules and does that process store energy or release energy?

Panama Canal, which took 10 years to build and opened in 1914, handles 5% of world trade.
The government of Panama recently initiated a project to expand the canal in order to
increase its share of global shipment, boost job creation, stimulate economic growth and
boost foreign exchange and tax revenue. Among other things, the expansion project involves
the building of a third set of locks that can accommodate mega cargo ships carrying up to
12,000 containers; at the moment the biggest ships that can navigate the canal carry 5,000
containers. The work was awarded to GUPC (Grupo Unidos por el Canal), a consortium of
international construction firms led by Sacyr of Spain. Others are Impregilo of Italy, Belgian
firm Jan De Nul and Constructora Urbana, a Panamanian firm. Work began in 2009 and was
expected to be completed in September 2014 at a total cost of $3.2 billion, according to the
contract.
As of January 2014, the work was already nine months behind schedule (with project
completion now expected in June 2015) and a cost overrun of $1.6 billion had been incurred
as of January 2013. According to GUPC, the cost overrun and schedule slippage were due to
“many and varied unforeseen costs which came up during these gigantic works... They are
technical matters, questions over cement ingredients, geotechnical matters, geological
questions, taxes matters, financial matters, labour issues and weather conditions". However,
Panama Canal Authority (APC), the Panamanian state-owned company responsible for
managing the canal and overseeing the project, attributed the problem partly to a delay of
four months shortly after the project began as a result of GUPC’s attempt to use low-quality
cement, which was rejected by the canal authority.
Since January 2013, there had been an escalating dispute over who should bear the additional
cost of $1.6 billion. The position of APC was that GUPC should respect the existing contract
by absorbing the additional cost, arguing that the cost overrun was due to events that were
"normal" in such a construction project. But GUPC said the cost overrun was due to
"unforeseeable" circumstances and delays caused by APC. On December 30, 2013, the
dispute had become so bad that GUPC threatened to halt work unless the Panamanian
government paid the money within 21 days. In response, the president of Panama, President
Ricardo Martinelli, threatened to go to Europe to demand that the governments of the
member firms of GUPC “take moral responsibility for what happened, because it is not
possible that a company puts such a huge extra charge on expansion work."
News of the suspension threat sent Sacyr’s shares plunging by more than 18% on the Madrid
stock exchange. On January 4th, 2014, Spain's minister for public works, Ana Pastor, flew to
Panama for an emergency meeting with President Martinelli and also met all the parties
involved to try to resolve the impasse. According to a spokesperson for Spain's foreign
ministry, "Panama is a country that is close and friendly towards Spain, and we share the
desire and interest to find a solution as soon as possible". Spain's ambassador to Panama,
Jesus Silva, added that all stood to lose out if the contract fell through.

1. Case Study 1: Government Intervention

In Germany in 2009 there was considerable debate about the extent to which the government should be intervening in the economy. For example, its citizens were worried about the future of Opel, a German car brand that was part of the ailing General Motors. Some wanted the government to make sure jobs were saved no matter what. Others, however, were more hesitant and worried about becoming the government becoming too interventionist. Traditionally since the Second World War the German government has seen itself as a referee in market issues and has avoided trying to control parts of the economy. It would regulate anti-competitive behavior, for example, but not try to run many industries. However, in the recession of 2009 when the economy was shrinking the government was forced to spend more to stimulate demand and had to intervene heavily to save the banking sector from collapse. The government also had to offer aid to businesses to keep them alive.

Questions

1. What are the possible benefits of a government intervening in an economy?

3. What prompted greater intervention by the German government in 2009?

4. What would determine whether the German continued to intervene on this scale in

the future?

Using Maven and Web Programming Basics

1. Build a program using maven 75 pts

A. Create file structure

Create a file structure for your program like the following:

web_app
→ src
→ main
→ java
→ resources
→ webapp
→ target

make sure you have in src/main/ the directories java, resources, and webapp.

In most Java IDEs (Eclipse, IntelliJ, etc.) you can make a maven project, which will have this structure by default (without the webapp directory), you can use that IDE tools then add the webapp directory.

B. Make pom.xml

Apache maven is a build automation tool that can compile and build your program as well as download any .jar dependencies you need. I’ll provide you with a pom.xml file with the parameters set to download the .jar files you need to make a web server in java. Put this file at the top level of your program file structure (same level as the the src and target directories). To verify you examined the file, change the value in the <name> tag from YOUR_WEB_APP to the name of your program. You can see all the jar files that are needed in <dependencies> and where the program is named in

<build>
<plugin>

<programs>

<program>

the file that sets up the tomcat program is in webDriver.Main (which I will describe later) and the program name is web (if you are doing the extra credit don’t change this)

C. Add tomcat driver

For this program we’ll be using the Apache Tomcat web framework (another popular one for java is Glassfish). In IDE you can use the Web Application projects to form your web program, but for this class I want you to build the web app driver so you can more easily publish your software and so you can see what is need to make a java web server.

To start make a package in src/main/java called webDriver (same as the name above), then add the provided Main.java file into that package (web_app/src/main/java/webDriver). If you see errors in your IDE your package names do not match (package webDriver) or you set up the pom.xml file incorrectly. Otherwise it should not have any errors. This class when run talks to the operating system to make your computer into a web server.

D. Create web.xml file

To help out your web server with some piping of traffic you need to setup a web.xml file. In your src/main/webapp directory create a folder called WEB-INF. In there put the provided web.xml file. This file helps direct traffic for the server, but it’s really simple for this homework, but we’ll build on it, in later assignments. To verify you have looked at the file, change the <display-name> value in the file, to your program name. The <welcome-file-list> gives the search order for the server’s default landing page.

E. Generate index.html

Finally you should have a working server to check if it works put an index.html page in src/main/webapp. I provided one, but you can put your own one in there.

To test if everything work, you’ll need to build the maven package. For windows users, open powershell or cmd, osX users open console, and terminal for Linux users, navigate to your project and type
mvn package

you should get a bunch of messages where the last five lines are similar to:
