Pedophiles constitute a heterogeneous group of sex offenders. Direct physiological assessment of sexual arousal has significantly increased our diagnostic skill and capability of monitoring treatment response. Erectile response studies have indicated that the majority of pedophiles and incest offenders show arousal to other paraphilias and frequently to appropriate adult sexual stimuli. Many sexual offenders deny or minimize their problem during initial interviews, but when confronted with laboratory results indicating deviant sexual arousal, they often acknowledge and elaborate on the paraphilia(s). Complete data and diagnoses are crucial in integrating treatment in the cognitive-behavioral paradigm. 相似文献

A unique mediation service using the telephone to help parents resolve conflicts over visitation ("access") is described. The program presented special advantages of low cost and high responsiveness to parents and their children and was designed to particularly benefit families that lacked the mobility or financial resources to participate in traditional face-to-face mediation. Because the service featured highly educated and experienced mediators and a child-focused, principle-based mediation approach, family members received reframing, refocusing, informative, and empathic assistance in understanding and dealing with their parenting disputes. Some 700 families and nearly 900 mediation cases were handled during the service's 19 months of operation, and some features of the families and the cases are described. Recommendations and directions for future research are included. 相似文献

This paper contributes to ard a better understanding of innovation in the service sector by focusing on the disparate nature
of R&D in the U.S. service sector as learned through case studies of the U.S. telecommunications, financial services, systems
integration services, and research and development testing services industries. Based on this understanding of the nature
and scope of R&D therein, a new policy-oriented model of innovation specific to the service sector is posited. Also, policy
recommendations are offered with regard to the public sector’s collection and interpretation of R&D data related to the service
sector.

The periodic Summits of the Americas are the highest form of regional multilateralism in the Western Hemisphere, but summits
lack their own means to implement their mandates. Hence, Summit Plans of Action assign many initiatives to existing regional
institutions, especially the Organization of American States (OAS) and the Inter-American Development Bank (IDB). But a notable
difference exists in the character and degree to which these two institutions have responded to their unfunded mandates, in
that the OAS has become “nested” under the hierarchy of summitry, while the IDB has eschewed subordination in favor of a “parallel”
relationship pursuing largely convergent activities. Relying on extensive interviews and reviews of open source and internal
documents, six variables are found to explain this differential response: ministerial authorities, competing mandates, institutional
missions, internal structures, membership and leadership. Yet for both regional institutions there remains a wide gap between
the directives emanating from the Summits and what the two regional institutions have been—and could be—accomplishing. The
study concludes with recommendations to improve institutional design.
