The current study presents the preliminary evaluation of the impact of pharmacological treatment (Selective Serotonin Reuptake Inhibitors and anti-androgens) on hypersexuality, sexual preoccupation and sexual compulsivity. The participant pool comprised 64 convicted UK sexual offenders who had been voluntarily referred for pharmacological treatment to reduce their hypersexual arousal, 51 of whom agreed to take the medication (with a further five individuals on hold or under assessment at the time of data extraction). The preliminary findings were very encouraging; analysis on measures assessing sexual preoccupation, hypersexuality and sexual compulsivity indicated a significant reduction between pre- and post-medication, across both types of medication. Limitations of the current research are discussed. 相似文献

Previous studies suggest access to and satisfaction with care may be different for enrollees in S-CHIP and Medicaid, but it is unclear whether those differences are fully explained by socioeconomic characteristics of the enrollees. We analyze access and satisfaction of three groups of children: Medicaid enrolled, S-CHIP enrolled, and children who are income eligible for Medicaid but carry a card similar to the state's S-CHIP children's card. Both enrollees and providers may believe that these children are enrolled in S-CHIP despite the fact that reimbursement is through the state's Medicaid system. Results indicate that the same network of providers treat, or are perceived by families to treat, the three groups differently. They support the notion that some of the differences in satisfaction between S-CHIP and Medicaid enrollees are related to unmeasured characteristics (for example, income) of the families in the different programs, but that programmatic identity contributes substantially to differential care experience. 相似文献

Most previous cap and trade programs have distributed emission allowances for free to incumbent producers. However, in the electricity sector the value of CO2 allowances may be far in excess of costs to industry and giving them away to firms diverts allowance value from other purposes. Using a detailed simulation model, this paper shows that compensation to firms losing asset value under a climate cap and trade policy can be achieved for a small fraction of total allowance value, if targeted carefully. However, the economic efficiency cost of providing incremental compensation to reach the fully compensated level is many multiples of that incremental compensation. These considerations might move policymakers away from free allocation of CO2 emission allowances in the electricity sector. © 2008 by the Association for Public Policy Analysis and Management. 相似文献
