1 Research Methodology EPH 7112 LECTURE : EXPERIMENTAL DESIGN

2 What is Ethics? Study of the morality of human actions From The American Heritage® Dictionary of the English Language, Fourth Edition, Morality – The quality of being in accord with standards of right or good conduct. A system of ideas of right and wrong conduct: religious morality; Christian morality. Virtuous conduct. Study of distinguishing right and wrong behavior

3 What is Ethics The science of determining what ought to be done in different circumstances and situations The objective is: To do good to most people Less harm to most people

4 Why is Ethics important? What goes around, comes around Act on behalf of society, as learned and professional community Satisfaction ….

5 How to solve “ethics” problems? Unlike technical field, solving problems related to ethics need several approaches Several ethical theories need and can be considered before making a decision This shows the level of complexity Although several theories are considered, ethical problem-solving usually leads to single solution

6 Ethical theory A moral theory defines terms in uniform ways and links ideas and problems together in consistent. This is exactly how the scientific theories used in other engineering classes function. Several theories are considered: Relativism Utilitarianism Duty ethics and rights ethics Virtue ethics

7 Relativism Ethical relativism assert that there is no accepted, universal definition of right and wrong. Ethics is relative to one's own society or organization. For example, in the West it is acceptable to kiss in public, rather unacceptable in the East. What do you think are the advantages and disadvantages of relativism?

8 Utilitarianism Utilitarianism holds that those actions are good if it serves to maximize human well-being. The emphasis in utilitarianism is not on maximizing the well-being of the individual, but rather on maximizing the well-being of society as a whole, and as such it is somewhat of a collectivist approach. For example, the building of a dam is acceptable although it disrupts the ecology and local household since it benefits society with drinking water and avoiding floods.

9 Utilitarianism Two main variations of utilitarianism: Act utilitarianism Rule utilitarianism Act utilitarianism focuses on individual actions rather than on rules. Rule utilitarianism holds that although adhering to these rules might not always maximize good in a particular situation, overall, adhering to moral rules will ultimately lead to the most good.

10 Cost-Benefit Analysis Tool to make a decision, for instance whether an engineering project is feasible or otherwise. There is a pitfall when this analysis is used for utilitarianism Easy to put $$ to cost and benefit when it is tangible. How is it when it relates to human life and livelihood?

11 Utilitarianism What do you think are the advantages and disadvantages of utilitarianism?

12 Duty ethics and Rights ethics These theories hold actions that are good as those that respect the rights of the individual. Here, good consequences for society as a whole are not the only moral consideration. Rights ethics holds that people have fundamental rights that other people have a duty to respect. In duty ethics, people have duties, an important one of which is to protect and respect the rights of others.

13 Virtue ethics Fundamentally, virtue ethics is interested in determining what kind of people we should be. Virtue is often defined as moral distinction and goodness. A virtuous person exhibits good and beneficial qualities. In virtue ethics, actions are considered right if they support good character traits (virtues) and wrong if they support bad character traits (vices).

14 Applied ethics Society would choose its ethical theory and then use that theory to derive an ideal set of rules for ethical behavior. Our society has a legal system that enforces a set of rules we live with as citizens and as members of our profession. But of course it was not derived purely from any single theory. You may find many legal things are regarded as not moral by some substantial segment of society.

15 Case Study #1 Improper Credit Given for Research Data Hadri is the head of a chemical company. As a part of a research and development effort, Hadri offers to provide funding to the chemical department of a major university for removing poisonous heavy metals (chromium, copper, lead, nickel, zinc) from waste streams. In return, the university agrees to give Hadri's company the exclusive rights to any technology developed in the field of water treatment or waste stream management. As a compensation, the university will also receive a royalty from the company from the profits derived from the use of the technology.

16 Case Study #1 At the university, a group of professors, led by Azim, decide to form a company to exploit the technology obtained except for water treatment and water waste management. Meanwhile, at the same time the university is conducting research in this, Hadri's company is conducting its own parallel research. Both teams obtain data and performance figures, and Hadri's company freely shares its results with those in Azim's company. Later, Ethan, a professor of civil engineering at the university, wants to conduct research and publish a paper relating to sewage treatment technology. He contacts the professors in the chemistry department, who furnish him with data from their tests, as well as with data from Hadri's company. Ethan is totally unaware that the results come from two parties.

17 Case Study #1 Ethan is successful in his research, and his article is published in a major journal. The data obtained by Hadri's company is displayed prominently in the paper, and makes up a major portion of the article. The paper credits the members of the chemistry department, but nowhere mentions the contributions of Hadri's company, even though their funds supported both projects. Ethan later learns that Hadri's company was the major contributor to the data in his paper. Is it plagiarism for Ethan to publish the data without publishing the full sources? Is it Ethan's obligation to give full credit to Hadri's company? --adapted from NSPE Case 92-7

18 Hadri Azim Ethan funding, royalty, data technology, information data PUBLISH!

19 Case Study #1 Code of Ethics Engineers shall give credit for engineering work to those whom credit is due, and will recognize the proprietary interest of others Engineers shall whenever possible name the person(s) who may be individually responsible for designs, inventions, writings or other accomplishments.

20 Case Study #1 Conclusion: It is not plagiarism if quotation comes from many sources. Ethan has an obligation to request that the journal publish clarification of the matter explaining how the matter occurred along with an apology for any misunderstanding which may have arisen as a result of the publication of the paper.

21 Case Study #1 Note: Ethan did not knowingly and deliberately fail to credit Hadri and his company for its contribution. However, Ethan should put more efforts to substantiate the sources contained in his paper; he should have then identified the sources. Azim otherwise is being unethical by misleading Ethan or failed to reveal the source of data.

22 Engineering ethics Ethics is the study of the morality of human actions Engineering ethics is the study of defining the proper courses of action when professional engineers deal with each other, their clients, their employers/ employees and general public

23 Engineering Ethics Engineering ethics can be different from general ethics to the extent that it takes into account: Relations between practicing professionals and their clients. Relations between the profession and society in general. Relations among professionals. Relations between employee and employer. Specialized technical details of the profession.

24 Engineering ethics Why is engineering ethics so important? Professionals posses specialized knowledge that is superior to that possessed by their clients, employers and the general public With this knowledge, a responsible and honest (read: ethical) engineer will be a useful member of the society An unethical engineer will tarnish the reputation of engineers, weaken the public’s confidence and become a dangerous member of the society

25 Moral foundations Moral foundations: Utilitarianism Duty Ethics Right ethics Virtue ethics

26 Codes of Engineering Ethics Engineers attempt to establish rules or standards of conduct for engineers No single code of ethics for all engineering societies However, a lot of similarities in different code of ethics from different societies

27 Importance of Code of Ethics To protect the public from abuse of knowledge As general guides to professional conduct Prevent reckless or malicious criticism among members To instil trust and confidence to the public on the profession

28 Code of Ethics Behave in an honorable and dignified manner. Protect the public safety, health, and welfare. Protect the environment. Perform duties only in areas of competence. Continue learning to sharpen technical skills. Be truthful and objective. Protect confidential information of employer or client.

29 Code of Ethics (cont.) Do not accept bribes, or gifts that would interfere with engineering judgment. Avoid conflicts of interest. Avoid injuring others, their property, reputation, or employment by false or malicious action Be involved with civic and community affairs.
