Title: Theory and research II (3/26)


1
Theory and research II (3/26)
  1. The input of theory to research
  2. Knowing how the e.g. of COP
  3. Macro regressions in States
  4. The conceptual scheme of One World

2
5 Inputs of Theory to the Research process
  • Conceptualization operationalization
  • Model Specification
  • Domain Specification (When?)
  • Generalization
  • Explanation (How? Why?)
  • In a research course you are mainly interested in
    whether a particular association exists.
  • In a theory course, you are interested in what it
    means and when, how and why?

3
Knowing How v. Knowing That
  • These issues are relevant to the kinds of
    disagreement that people have analyzing the data
    on the effects of poverty (e.g. INCOME _at_16) and
    culture of poverty (e.g. FAMILY _at_16) on
    opportunity (e.g. RANK).
  • That is, there are issues of conceptualization
    and measurement.
  • And, there are issues of interpretation of the
    coefficients and partial coefficients.

4
Levels Re Culture of Poverty
We have discussed the relation of poverty and
culture of poverty several times. It is useful
to think how these levels might relate to the
data that we analyzed last Monday. (See Below)
Kind of Assumption Example Re Culture of poverty
General ideas about causality In analyzing data on culture of poverty, are there general issues about causality creating disagreement?
Causal Imagery Do different theorists have different ideas about what kinds of things are affecting what other kinds of things?
Classification of causes What are the main structures and dynamics relevant to the analysis of the culture of poverty?
Kinds of causes affecting other kinds What are the main theories about the negative effects on opportunity of poverty and of culture of poverty?
Thesis that a variable explains variation in another variable What do the main theories about the effects of poverty and culture of poverty imply, empirically?
Empirical consequences in particular conditions Empirically, what are the effects of INCOME _at_16 controlling FAMILY _at_16 and vice versa?
View that some particular data are examples of a concept What does this particular data suggest of show about the effects and dynamics of culture of poverty?
5
I Theory and Operationalization
  • In order to see whether X Y , you want
    to get an index or measure of X and one of Y and
    see whether and when they are associated such at
    when there is more X there is more Y.
  • An index or measure is an observable in some data
    set that you have reason to suppose is associated
    with the underlying variable of interest.
  • E.g. is FAMILY _at_16 and index of Culture of
    Poverty? Arent some rich families not intact?
  • Note you often only operationalize a part of a
    theory .

6
What is the effect of measurement error?
  • Suppose that your index has a lot of noise in it
    so that it is not a very good measure of the
    underlying variable.
  • This will usually just attenuate the
    relationship, making it appear weaker than it
    really is,
  • So that the data is a conservative test of the
    hypothesis.
  • Noise is different from bias.

10
II Theory and model specification
  • Whenever one looks at any causal relation
    empirically, there are always an indefinitely
    large number of other forces going on.
  • The overall assumptions about the forces that are
    operating are established and justified by
    theory.
  • A crucial element of model specification is
    causal order. Does INCOME _at_16 RANK or does
    RANK INCOME _at_16 ?

11
Why do we care which way?
  • The observable data often do not prove which way
    the causal arrow goes.
  • Some people in the 1950s then said, Lets stick
    with what can be proved from the data
    (associations) rather than causal inferences.
  • Almost no one believes that what is important
    and interesting is the underlying causal forces
    that brought about the associations.

12
Why Systems and Feedbacks are Inconvenient
  • Often there are a lot of specific causal
    influences that have been demonstrated.
  • But it is not clear how they fit together what
    is their dynamic under what conditions the
    effects obtain, etc.
  • Whenever there are feedbacks, the problems become
    intricate.
  • E.g. Myrdal.

13
Systems and feedbacks about the culture of poverty
  • Virtually all sociologists would agree the
    poverty and the culture of poverty are mutually
    reinforcing.
  • Most would also agree that INCOME _at_16 is a
    reasonable measure of the effect of poverty and
    that broken families (e.g. FAMILY _at_16) are a
    reasonable measure of culture of poverty.

14
Why Systems and Feedbacks are Inconvenient
  • Often there are a lot of specific causal
    influences that have been demonstrated.
  • But it is not clear how they fit together what
    is their dynamic under what conditions the
    effects obtain, etc.
  • Whenever there are feedbacks, the problems become
    intricate.
  • E.g. Myrdal.

15
Clues about Causal order and systems dynamics
  • The size and the relative size of the empirical
    associations and partial associations gives one
    indications of the system dynamics.
  • But one will always have to make model
    specification assumptions.
  • These must be theoretically motivated.

16
Controls
  • Some people believe that giving poor childrens
    parents money (e.g. AFDC) will largely or
    entirely fix the problems of those poor children
    who also have broken homes (which is many of
    them.)
  • Partly they believe that this will cause fewer
    homes to break up.
  • Some people believe that fixing childrens
    broken homes (e.g. faith based programs) will
    largely or entirely fix the problems of poor
    children.
  • Partly they believe that this will pull most of
    the homes out of poverty.
  • The size and the relative size of INCOME_at_16
    effects and FAMILY _at_16 effects can be suggestive.
  • The effect of one, controlling the other is even
    more sugestive.

19
Controls as an answer to because
  • Ordinarily if there is a relations between X and
    Y and you control T, and the original
    relationship goes away, that means that the
    original relationship is due to or because of
    the controlled variable.
  • And if there is a relations between X and Y and
    you control T, and the original relationship does
    not go away, that means that the original
    relationship is not due to or because of the
    controlled variable.
  • And if there is a relations between X and Y and
    you control T, and 1/3 the original relationship
    goes away, that means that 1/3 the original
    relationship is due to or because of the
    controlled variable.

20
What can we conclude from the data?
  • What does it prove that the partial gamma of
    INCOME _at_16 controlling FAMILY _at_16 is about the
    same as the bivariate?
  • What does it imply?
  • What does it suggest?
  • What does it prove that the partial gamma of
    FAMILY _at_16 controlling INCOME _at_16 is a little
    smaller than the bivariate?
  • What does it prove that gamma is -.179
  • What does it imply?
  • What does it suggest?

III) Domain Specification
  • A theory is a claim.
  • Usually it applies to some set of cases more
    limited than all social structures in all of
    recorded history,
  • but much more general than the cases on which the
    claim is based.
  • Theory involves establishing the domain of the
    theory.
  • Statistical interactions are the main clues about
    domains.
  • A mechanism (a WHY?) establishes a general
    domain.
  • If the coins in my pocket are quarters because of
    the hole in the bottom of my pocket, then the
    coins will be quarters whenever such a hole
    exists.

23
IV) Generalization
  • Particular findings, empirical generalizations,
    and hypotheses (e.g. Protestants have higher
    suicide rates) need to be related to more general
    processes.
  • Conceptualization (e.g. deviance rather than
    crime or suicide) is partly a matter of
    generalizing.

24
Theory simplifies to the essential
  • It is trivially true that both
  • functional and conflict processes operate
  • and that
  • Culture influences social structure,
  • and social structure influences culture.
  • and also that
  • individuals create social structures and social
    structures shape individuals.
  • However, it is also trivially obvious that any
    theory must simplify, and that models that
    include everything are usually too complex to use
    or test.

25
V) Explanation
  • The conceptualization, and the establishment of
    the conditions and size of the effects is basic
    to establishing what is the mechanism that brings
    it about.
  • The main paradigms propose mechanisms.

26
SummaryTheory and research
  • Research establishes that there is an
    association.
  • Theoretical questions involve Why? How? and When?
  • I.e. what direction does the causal arrow run in,
    under what circumstances, why and how?
  • Often it is only the cumulative result of the
    scientific process over generations

27
The main paradigms in sociology
  • P. 267-276 of OW shows that the different maps of
    the main theoretical positions in sociology can
    be translated into each other.
  • They boil down to two dimensions functional v
    conflict and micro v macro. However
  • The 20-odd different sections of sociology such
    as medical sociology contain importantly
    different theoretical positions.
  • Any way of dividing the 20,000 or so practicing
    sociologists into a small number of schools is
    bound to simplify

28
The main map
Functional macro-theory e.g. Durkheim, Parsons Organizational- macro-theory e.g. Webers rationalization Conflict macro-theory e.g. Marx
Functional microtheory e.g. some aspects of Merton Interactionist micro-theory e.g. Mead Conflict micro-theory e.g. Mills
29
Organization theories as a Mix
  • The interactionist/organization theories stemming
    from Weber, Mead, and others, can be viewed as an
    ambivalent synthesis of elements of conflict and
    functional theory.
  • Often the elements that distinguish them from
    functional or conflict theory appear at the micro
    level.

30
Micro-theory v Macro-theory
  • Micro-theories mainly treat social structure as
    the outcome of individual choices and actions.
  • Parsons took Webers action theory as the main
    model.
  • Other American sociologists took George Herbert
    Meads interactionism as a model.
  • The main difference between rational-action
    theories stemming from Weber and symbolic
    interaction theories, stemming from Mead is the
    nature of the tinker-toy, but they are both
    tinker-toy models.

31
Macro-theory
  • Macro-theories focus on the fact that humans and
    human behavior is shaped by the social structure.
  • This leads to concentrating on how social
    structures influence their members and other
    social structures.
