Rationalism in management science tends to mean attempting to determine the benefits and costs of the alternative decisions under consideration, and then picking the one that is best on benefits minus costs. Incrementalism tends to mean determining the decisions that actually get made under various circumstances, and then working with those existing decision rules as the basis for making adjustments to consider special or changing circumstances. Those two approaches can be well illustrated with the problem of attempting to determine what criminal sentences should be legislated to cover given crimes and prior records. The analysis tends to show that a rationalist approach is more effective in achieving societal goals when (1) alternative policies can be meaningfully related to those goals, and (2) existing decisions reflect individual goals which are generally in conflict with societal goals. An incrementalist approach is more effective when either of those criteria is absent, which is so when seeking to arrive at legislatively determined nondiscretionary criminal sentencing.  相似文献

The growth of the planning function of government raises the question of how planning can be accomplished by democratic means. A new technological device—the teaching computer—seems to be ideally suited for disscussions between experts and the public on issues of medium and long-range planning. The teaching computer can be thought of as a mass communications system with feedback.The author wishes to acknowledge research support from the Program on the Social Implications of Science and Technology at the University of Illinois under National Science Foundation grant GR-60.

This longitudinal investigation examined main and interactive effects of coparent support and conflict on mother and child adjustment in 248 low-income, African American, single mother-headed families. The findings indicated that coparent conflict was a more robust predictor of mother and child maladjustment both cross-sectionally and longitudinally than was coparent support. Moreover, findings revealed that coparent conflict and support interacted to predict one parenting behavior, monitoring, both cross-sectionally and longitudinally. Coparent relationships characterized by high levels of support and low levels of conflict were associated with the highest levels of parental monitoring behavior, whereas coparent relationships characterized by low levels of support and high levels of conflict were associated with the lowest levels of monitoring. The findings highlight the importance of examining both positive and negative aspects of coparent relationships in this at-risk, but understudied, group.  相似文献

Substantial research has focused on the negative associations between coparenting conflict, parental psychological functioning, and parenting behavior in European American, middle-income, families. However, less attention has been given to ethnic minority families and to families that are nontraditionally structured. In an effort to address this gap, the current longitudinal study examines the relation between conflict with the mother-identified primary co-caregiver and parenting practices in single parent, economically disadvantaged African American families. Participants included 234 mother–child dyads. It was hypothesized that conflict would relate to less utilization of positive parenting practices and that this association would be mediated, at least in part, by maternal psychological distress. Hypotheses were examined using structural equation modeling (Lisrel 8.3): Conflict with a co-caregiver was significantly related to parenting both directly and indirectly through maternal psychological distress. Implications of the findings are discussed.

There are two approaches to predicting election outcomes: (1) a historical approach, which uses past election results alongside macroeconomic and political variables to forecast election results up to a year in advance, and (2) a campaign-oriented approach, which uses current campaign trends to forecast vote shares at the end of the campaign. They are in some way at odds—one approach says the campaign doesn't matter, the other focuses entirely on the campaign. This article considers whether the two approaches might be usefully combined; it considers whether the prediction errors in historical models may be related to trends during the campaign. That possibility is tested here using 17 elections in the US, UK and Canada, combining historical predictions and automated content analyses of campaign-period media content. Results suggest that campaigns do not account for errors in the historical predictions; but there may be other ways in which campaigns matter in conjunction with historical models.  相似文献

The substantial increase in the enrollment of women in batterer intervention programs (BIPs) over the past 30 years has greatly outpaced research on women who perpetrate intimate partner violence (IPV). As a result, it is unknown whether existing programs, which were originally designed to treat male perpetrators, are effective at preventing recidivism among women. Recent research shows that men who perpetrate IPV may also aggress against nonintimate partners, children, and animals, and that the reach of their aggressive tendencies has implications for treatment. Conducting similar investigations on women who perpetrate IPV may help to inform treatment delivery in BIPs. This study examined the prevalence of adulthood animal abuse perpetration and its association with psychological and physical IPV perpetration in a sample of women arrested for domestic violence (N = 87). Seventeen percent (n = 15) of the women committed at least one act of animal abuse since the age of 18, in contrast to the 0.28% prevalence rate reported in the general population. The overrepresentation of animal abuse in this sample was consistent with that of men arrested for domestic violence. Furthermore, women who reported committing animal abuse as an adult showed moderately higher rates of psychological aggression and physical assault perpetration against their partners, relative to women who did not report animal abuse. Implications for future research are discussed.  相似文献

Drawing on two experiments embedded in online surveys, this article examines the impact of news photos on support for military action. In 2011, respondents were asked about support for ongoing military involvement in Afghanistan while being randomly exposed to one of two photos—one of a soldier with a child, the other of a soldier with a gun. The former photo increased expressed support for war; and the effect was greater for those who self-identify as being very interested in international affairs. Three years later, a follow-up experiment was fielded that looked both at the past intervention in Afghanistan and ongoing interventions in Syria; results were very similar. Both experiments speak to the potentially profound role of mass media in generating support (or not) for foreign military engagements, and the increased impact of frames on those who are more attentive to the issue domain.  相似文献
