This paper elaborates a model of problem representation first presented by Billings and Hermann (1998) . The foreign policy process begins when decision-makers specify policy goals and identify relevant constraints in response to a perceived problem. Although this initial problem representation often sets the course for subsequent policy, unanticipated constraints can arise that catch decision makers off-guard. Finding themselves in a context they did not anticipate to be in, decision makers may choose to alter their representation of the problem and/or change the course of policy. Billings and Hermann offer one piece of this puzzle by examining how decision makers re-represent problems; this paper provides the second piece by assessing how policies, not representations, change in response to new constraints. A case study of the U.S. response to the Ethiopian famine in the mid 1980s demonstrates that policy does not always follow problem representation. 相似文献

Attitudes towards social attachment and bonding were evaluated in groups of maximum (N=48) and bonding were evaluated in groups of maximum (N=46) security prison inmates and compared with the attitudes of a group of 49 noncriminal college students. Three primary
styles of attachment were considered: avoidant, ambivalent/anxious, and secure. It was predicted that the maximum security
condition, a group hypothesized to contain a large number of lifestyle criminals, would evidence more of an avoidant style
of attachment compared to minimum security inmates or a group of college student controls. Consistent with this hypothesis,
the maximum security inmates exhibited greater avoidance in their attitudes towards relationships than subjects in the other
two conditions. The implications of these results are discussed. 相似文献

The present study was designed to examine effects of closed-circuit technology on children's testimony and jurors' perceptions of child witnesses. For the study, a series of elaborately staged mock trials was held. First, 5- to 6-year-old and 8- to 9-year-old children individually participated in a play session with an unfamiliar male confederate. Approximately 2 weeks later, children individually testified about the event at a downtown city courtroom. Mock juries composed of community recruits viewed the trials, with the child's testimony presented either live in open court or over closed-circuit television. Mock jurors made ratings concerning the child witness and the defendant, and deliberated to reach a verdict. Results indicated that overall, older children were more accurate witnesses than younger children. However, older, not younger children produced more inaccurate information in free recall. Compared to live testimony in open court, use of closed-circuit technology led to decreased suggestibility for younger children. Testifying in open court was also associated with children experiencing greater pretrial anxiety. Closed-circuit technology did not diminish factfinders' abilities to discriminate accurate from inaccurate child testimony, nor did it directly bias jurors against the defendant. However, closed-circuit testimony biased jurors against child witnesses. Moreover, jurors tended to base their impressions of witness credibility on perceived confidence and consistency. Implications for the use of closed- circuit technology when children testify are discussed. 相似文献

While research has repeatedly demonstrated that interparental conflict is related to poorer child/adolescent functioning in the areas of internalizing and externalizing problems, as well as prosocial and cognitive competence, the particular relevant dimensions of the conflict have yet to be studied. The present study examined the contributions of three different dimensions of conflict to these difficulties in adolescent functioning. Forty-eight mother-father-adolescent triads participated by completing questionnaires regarding the following dimensions of their interparental conflict: frequency, method of handling, and outcome. Assessment of adolescent functioning was obtained independently through teacher-completed measures of internalizing and externalizing problems and prosocial and cognitive functioning. The results of correlational analyses indicated that father-completed measures, particularly the use of verbal and physical aggression to handle conflict, were related to all four measures of adolescent functioning. In contrast, mother-completed measures were not related. Multiple regression analyses were also conducted. For all four measures, either father physical or father verbal aggression entered first and accounted for 17 to 48% of the variance across the four dependent measures. No other indices of conflict individually accounted for a significant portion of the variance beyond that accounted for by father's verbal or physical aggression. Possible explanations for the relationship between father's method of handling of conflict and adolescent functioning are discussed. 相似文献
