Do parties change their platform in anticipation of electoral losses? Or do parties respond to experienced losses at the previous election? These questions relate to two mechanisms to align public opinion with party platforms: (1) rational anticipation, and (2) electoral performance. While extant work empirically tested, and found support for, the latter mechanism, the effect of rational anticipation has not been put to an empirical test yet. We contribute to the literature on party platform change by theorizing and assessing how party performance motivates parties to change their platform in-between elections. We built a new and unique dataset of >20,000 press releases issued by 15 Dutch national political parties that were in parliament between 1997 and 2014. Utilizing automated text analysis (topic modeling) to measure parties’ platform change, we show that electoral defeat motivates party platform change in-between elections. In line with existing findings, we demonstrate that parties are backward-looking.  相似文献

This paper analyzes the role of coordination criteria in employment and training service delivery within the Job Training Partnership Act system. The evolution of coordination criteria is related to current initiatives in the Employment Service at the state and local levels. An operational set of program outcome measures for monitoring coordination efforts is discussed. This set of outcome measures is formulated in the broad context of stabilizing employment and averting the "structuralization" of unemployment impacts wrought by fundamental economic change in the labor market. The assessment and monitoring of such coordination efforts is discussed.  相似文献

Studies of involuntary outpatient commitment (OPC) among persons with severe mental illness have concluded that OPC is only effective in improving treatment outcomes when it is sustained for 6 months or longer and is combined with frequent outpatient services. This article explores factors that influence the delivery of outpatient services to subjects in a randomized trial of OPC and finds 2 general patterns. Outpatient visits were more frequent among all subjects with apparent clinical need, regardless of study assignment, and among subjects whose OPC was sustained beyond an initial court order. These results suggest that, in practice, sustained OPC represents a consensual agreement between clinicians and the court to more intensively address the complex needs of persons with severe and persistent mental illness.  相似文献

In order to understand the precursors to sexual offending among youth and the associated gender differences, the records of 813 sexually abusive children (659 boys and 154 girls) referred for an evaluation of their sexually inappropriate and coercive behavior were reviewed and coded. These children ranged in age from 3 to 18 when they committed their first hands-on offenses. All were under the care of the Massachusetts Department of Social Services either prior to or as a result of their behavior. Principle findings included: (1) a high proportion of girls (19 percent) in a sample of children flagged as sexually abusive to other children, (2) an exceptionally high base rate of severe maltreatment and associated clinical and psychiatric sequelae, and (3) girls were significantly more likely to be sexually abused, and when sexually abused the abuse lasted longer, was more severe, and involved more perpetrators. In addition, the girls were significantly more likely to witness domestic violence and to witness sexual deviance within the home. For all other types of abuse, there were no group differences, and (4) all of the children were subjected to a very high level of caregiver instability.  相似文献
