Policy analysts, like allegorical homesteaders, face the seemingly unmanageable task of coping with the wilderness of ill-structured problems, while concurrently attending to well-structured problems, which can be addressed with conventional methods of policy analysis. What has appeared thus far as an unmanageable task may become manageable once analysts acknowledge the principle of methodological congruence: The appropriateness of a particular type of method is a function of its congruence with the type of problem under investigation.
To be sure, conventional methods of the first type are appropriate and useful for solving first-order problems, which are relatively well-structured. Contexts of practice, however, are pervaded by second-order problems which, variously described as squishy, messy, or ill-structured, are the class of all first-order problems. Just as methods of the first type are congruent with the simple analytic demands of first-order problems, so are methods of the second type congruent with the complex analytic demands of second-order problems. When policy analysts fail to observe this principle of methodological congruence they are likely to solve the wrong problem.
Methods of the second type are not limited to general heuristics, but include specific and readily comprehensible procedures for estimating the boundaries and structure of ill-structured problems. Since these estimation procedures appear to satisfy requirements of inductive estimates in general, policy analysts can assess their own performance in providing approximate answers to the right question, thus coping with the enemies who lurk in the wilderness of conventional policy analysis. 相似文献

The purpose of this paper is to present the horizontal sectioning technique used by odontologists at the Central Identification Laboratory to sample dentin for mtDNA analysis. From the perspective of DNA testing, anthropologists and odontologists at the Central Identification Laboratory work with ancient remains. In many instances, the lack of comprehensive antemortem records, the potential for fragmentation and commingling, and environmental exposure makes the use of traditional forensic identification techniques difficult or impossible. Teeth are highly resistant to environmental degradation and are an excellent source of mitochondrial DNA (mtDNA). This technique is simple, quick, and relatively conservative, allowing for preservation of the majority of the external portion of the tooth structure. 相似文献

Theoretically based hypotheses regarding psychosocial antecedents of unwed motherhood among indigent adolescents are tested. Data regarding psychosocial antecedents were obtained from a survey of a 50% sample of seventhgraders in a large urban school system. Hypotheses were tested by comparing three groups of subjects from among these respondents: (1) 82 female adolescents who received perinatal care at an adult development clinic for indigent adolescents (all gave birth out of wedlock at least one year following the baseline survey and prior to their eighteenth birthday); (2) 164 matched (by race, mother's education, and school) controls — two matches for each pre-unwed mother; and (3) 164 randomly selected controls — two controls for each preunwed mother. The results were consistent with the assertion that deviant behaviors related to and including unwed motherhood are alternative deviant responses to the subjectively recognized inability to defend against self-rejection in the course of membership group experiences in anticipation of self-enhancing consequences of the deviant behaviors. The positions in the social structure occupied by the pre-unwed mothers predispose the subjects to deviant responses by (1) increasing the probability of self-devaluing experiences and the subjective association of these experiences with the normative structure and (2) offering highly visible deviant alternatives that offer greater self-enhancing potential than the perceived low self-enhancing potential of the normative environment. The deviant patterns to which the subjects are predisposed are in fact adopted when prior social controls effictively exercised by parental and school authorities erode (as a result of the subject's identification of family and school as persistent sources of self-devaluing experiences). The specific modes of deviance adopted, including patterns associated with unwed motherhood outcomes, are apparently consistent with subculturally influenced values and adaptive/coping/defensive patterns. The total pattern of findings suggests that the same general theory of deviant behavior that has been applied to other modes of deviance is appropriate in understanding precursors of unwed motherhood among indigent adolescents.Received his Ph.D. in sociology from New York University in 1958.

Programs for widespread dissemination of birth control information and devices among adolescents are subject to strong resistance from many groups and may be ineffective anyway. An alternative approach to reducing the alarming frequency of unplanned pregnancy among unmarried adolescents might be group or individual counseling for those most susceptible, to unplanned pregnancies. Accurate identification would be necessary to implement this alternative. Developed in this paper is an inferential strategy for identifying in well-defined groups unmarried adolescents who seem susceptible. When carefully evaluated, an inferential strategy, based, on several concepts from Bayesian inference theory, appears remarkably accurate as a means of identification.

In recent years a number of important science policy issues have rentered on questions about the social utility of science. The field of knowledge systems accounting has evolved as a special form of social impact assessment to observe and measure the impact of science on society. A system of social impacts of science (SIS) indicators has been developed as an attempt to represent these complex patterns and relationships. In the final analysis, the causal relevance of science to social performance depends on our capacity to link the complex knowledge system of modern science to the achievement of social goals. 相似文献
