Conducting child custody evaluations is one of the most complex, challenging, and sometimes risky professional endeavors that a mental health professional can perform. This article examines the professional and personal challenges which may be encountered by the evaluator. In addition to discussing the role requirements and need to maintain awareness of bias and countertransference, challenges such as coping with state board or ethics complaints and possible risks to personal safety are also addressed. Suggestions for risk management and coping with the demands of these assessments are offered, as well as the benefits and rewards of engaging in this important work.  相似文献

This article explores theoretical and empirical issues in the application of clinical neuropsychological evidence to forensic issues in the criminal law. The nature of forensic neuropsychological evaluations is discussed with reference to issues of competency to stand trial, criminal responsibility, and other competencies in the criminal process. Examples of specific disorders relevant to criminal law standards are presented, together with data estimating the prevalence of brain dysfunction in criminal and forensic populations. Research is also reviewed on the role of neuropsychological brain dysfunction in the etiology of violence and criminally relevant behavior. Finally, empirical and ethical issues concerning the applicability and admissibility of forensic neuropsychological data in the criminal context are discussed.  相似文献

Technology policies and their effect on technology transfer from defense to civilian industries in Israel from 1967 to 1995 are explored. Defense technology policy is found to drive the growth of the defense industry and to limit defense conversion to commercialization initiatives developed primarily through intra-organizational technology transfer. The case of the Israel Aircraft Industries (IAI) is presented. Also the development of national technology policy in Israel is traced and found wanting. Civilian and defense technology policies are found to be uncoordinated with each other and together are incapable of producing interorganizational technology transfer so as to significantly effect defense conversion on a wide number of economic actors particularly small firms. To achieve a socially effective defense conversion process (in which technologies are transferred from defense firms to many economic actors), the analysis suggests that a national technology policy should be designed and implemented under Prime Minister's leadership.  相似文献

Optimal Law Enforcement with a Rent-Seeking Government   总被引:1,自引:0,他引:1  
This article analyzes public and private law enforcement whenthe government is motivated by rent seeking. A rent-seekinggovernment seeks primarily to maximize revenue. The articleconcludes as follows: (1) if offenders have sufficient wealth,a rent-seeking government is more aggressive than a social-welfare-maximizinggovernment in enforcing laws against minor crimes (such as parkingviolations) but more lax in enforcing laws against major crimes;(2) competitive private enforcement is usually better and neverworse than monopolistic private enforcement; (3) The choicebetween competitive private enforcement and public enforcementdepends on which is cheaper and on the severity of the offense.  相似文献

Telecommunications regulation has experienced a fundamentalshift from rate regulation to increased reliance on compelledaccess, perhaps best exemplified by the Telecommunications Actof 1996's imposition of no fewer than four new access requirements.Unfortunately, each access requirement is governed by a separateset of rules for determining both the scope and the price ofaccess. The resulting ad hoc regime has created difficult definitionalproblems and opportunities for regulatory arbitrage. In thisarticle we propose a system inspired by the discipline of mathematicsknown as graph theory that integrates all of the different formsof access into a single analytical framework. This system separatesdifferent access regimes into five categories: (1) retail access,(2) wholesale access, (3) interconnection access, (4) platformaccess, and (5) unbundled access. It also provides insightsinto how each type of access complicates the already difficultproblems of network configuration and management and introducesinefficient biases into decisions about network capacity anddesign. The approach we propose also provides insights intothe transaction cost implications of the different types ofaccess. Drawing on the Coasean theory of the firm, our approachexamines the tradeoffs between internal governance costs andthe external transaction costs of providing access to offera theory of network boundaries. This framework shows how accessregulation distorts networks' natural boundaries and providesa basis for evaluating whether private ordering through marketswould lead to more efficient network design.  相似文献
