The Tax Reform Act of 1986 rewrote the federal income tax code, bringing it closer to policy professionals' vision of what constitutes an equitable and efficient income tax. Research on tax compliance suggests the law might have affected taxpayer compliance in three ways: by reducing opportunities to overstate deductions, by changing perceptions of fairness, and by altering tax liabilities. Changes in taxpayer perceptions, attitudes, and noncompliance intentions were examined in three bodies of survey data, each containing pre-and post-reform data from independent samples of the same population. The results show an improved normative climate for taxpayer compliance and point to both the feasibility and the importance of examining the effects of substantive tax policies on taxpayer perceptions, attitudes, and behavioral intentions. 相似文献

The formation of adequate mental health systems within prisons has accelerated as a result of successful class action lawsuits. Our recent national survey questioned all state correctional departments about the existence of standards in each system, compliance with such standards, prevalence of class action lawsuits involving the issue of providing adequate mental health services for inmates, issues related to consent decrees, available mental health resources within the correctional system, and the administrative structure of the mental health system. Our purpose was to identify those factors correlated with certified class action lawsuits involving issues related to mental health services. Twenty-one states were involved in such litigation. Only the presence of psychiatric hospitals operated by the department of corrections correlated with the presence of certified class action lawsuits involving mental health services. Prison systems larger than 15,000 inmates were at higher risk for such litigation. Smaller systems having psychiatric hospitals run by the state mental health agency appeared to be at less risk for such litigation. 相似文献

Reviewing public administration in Australia was once akin to watching glaciers — you knew there was movement and something was happening beneath the surface, but detection required patient observation over a long period of time. 相似文献

Misidentification syndromes have been studied from a variety of perspectives, including phenomenological, biological, and nosological approaches. More recently, misidentification syndromes have been studied from a psychiatric-legal perspective, especially with regards to the problem of dangerousness. Capgras syndrome and other syndromes of misidentification can lead to hostile mood and subsequent physical violence. Little attention has so far been devoted to children as the objects of the psychotic person's misidentification delusion(s). We provide a review of cases from the anglophonic literature that have children as the misidentified objects, add three new cases, and then discuss the relationship between misidentification and potential harm to these children. 相似文献

The present study investigated the extent to which psychosocial development through the first five stages of Erik Erikson's theory of personality development is associated with Diagnostic and Statistical Manual (third edition, revised; DSM-III-R) Axis II personality disorder symptomatology in a late adolescent sample of undergraduate students. The Inventory of Psychosocial Development (IPD) and the Personality Diagnostic Questionnaire—Revised (PDQ-R) were administered to a mixed-sex sample of 106 undergraduate students. The results of this research were that IPD scores assessing negative resolutions of the first five Eriksonian developmental stages consistently predicted scores on the PDQ-R composite scale and the PDQ-R impairment/distress index—both measures of overall personality disorder symptomatology. The IPD subscales varied substantially in the extent to which they predicted scores on the 13 PDQ-R subscales that assess symptoms of specific DSM-III-R personality disorders—ranging from the trust vs. mistrust subscale, which predicted scores on 12 of the 13 PDQ-R subscales, to the initiative vs. guilt subscale, which predicted scores on only 6 of the 13 PDQ-R subscales. Implications of these findings for our understanding of the relationship between psychosocial development and psychopathology are discussed in the context of previous research in this area, and suggestions for future research are offered.Received Ph.D. from Temple University.

Compulsory competitive tendering (CCT) has been an important instrument of Conservative government economic policy since 1979. Its effectiveness in generating cost-effective services depends on competition to supply the service in question.
The NHS domestic market is large and, prior to the introduction of CCT, promised to be profitable for contractors. Many contract cleaners with office cleaning experience entered. In the event the costs of entry were heavy, and the profit margins of established firms were reduced. When contracts have been awarded to firms, they tended to be to those with a track record. Many firms therefore withdrew; and the few that remained have profit margins in the NHS little different from those found elsewhere. Of more than by firms with a serious interest in entry, probably no more than a handful can have come out of the experience in net profit in the first seven years.
The experience of CCT in the market for NHS domestic services has shown that a degree of competition in the market can be achieved, arguably because of the presence of direct service organizations. Competition for this market, on the other hand, can be limited by the high costs of entry. 相似文献
