  • Introduction

  • IntroductionHands-on approachInclude what should not be done?Research Methodology for Public Administration Research Methodology for Social Sciences

  • Salient Feature Interdisciplinary/integrated approach /Generalist ( specialist)

  • Why important?Understanding e.g., research is not just pollingAbility to evaluate research project(distinguish good research from poorly-designed research) To find practical policy solutions

  • Policy ResearchSerious research (strong enough foundation to provide credible policy recommendations) Policies really drawn from findings of research, not from researchers opinions /judgments

  • Peer ReviewWhite Paper // Environmental Impact Assessment (EIA)Social Impact Assessment (SIA)Health Impact Assessment (HIA)

  • : Positive vs Normative Questionspositive questions firstNeed to know what is or how/why things work the ways they do What works/doesnt work? before we could provide answers for normative questions What should be?What is to be done?Where to begins?:

  • Paradox of ThriftIn Keynesian macroeconomics, the "paradox of thrift" is an example of this fallacy: increasing saving (or "thrift") is obviously good for an individual, since it provides for retirement or a "rainy day," but if everyone saves more, it may cause a recession by reducing consumer demand.

  • TautologyThe American Heritage Dictionary of the English Language (2000) Tautology: 1a. Needless repetition of the same sense in different words; redundancy. b. An instance of such repetition. 2. Logic An empty or vacuous statement composed of simpler statements in a fashion that makes it logically true whether the simpler statements are factually true or false; for example, the statement Either it will rain tomorrow or it will not rain tomorrow.

  • Ecological fallacy The ecological fallacy occurs when you make conclusions about individuals based only on analyses of group data. 1 .. ..

  • False Dilemma/Dichotomyfalse dilemmaalso known as false choice, false dichotomy, falsified dilemma, fallacy of the excluded middle, black and white thinking, either/or fallacy involves a situation in which two alternative statements are held to be the only options, when in reality there exist one or more other options which have not been considered.

  • A typical false dilemma is the assertion "You are either for us or you are against us." The fallacy of this type of argument is that it tries to eliminate the middle ground.

  • The two alternatives presented are often, though not always, the two extreme points on some spectrum.

  • A false dilemma may not necessarily be limited to two choices; it may involve three possibilities, in which case it is known as a trifurcation, or more, in which case the dilemma may be more the result of accidental omission than deliberate intent.

  • Romanticism / nostalgiaThe Good Old Days ()

  • Romanticism / nostalgia ()A tablet from ancient Assyria, about 2800 BC. (almost 5,000 years ago), has been found that states: Our earth is degenerate in these latter days. There are signs that the world is speedily coming to an end. Bribery and corruption are common. More than 2,000 years later, Socrates complained, Children are now tyrants They no longer rise when elders enter the room. They contradict their parents, chatter before company, gobble up dainties at the tables, cross their legs, and tyrannize over their teachers.Plato (Socrates student) wrote of his students: What is happening to our young people? They disrespect their elders, they disobey their parents. They ignore the law. They riot in the streets inflamed with wild notions. Their morals are decaying. What is to become of them?
