We demonstrate the asymptotic equivalence between commonly used test statistics for out‐of‐sample forecasting performance and conventional Wald statistics. This equivalence greatly simplifies the computational burden of calculating recursive out‐of‐sample test statistics and their critical values. For the case with nested models, we show that the limit distribution, which has previously been expressed through stochastic integrals, has a simple representation in terms of χ2‐distributed random variables and we derive its density. We also generalize the limit theory to cover local alternatives and characterize the power properties of the test. 相似文献

To explore how people experience grief and what factors are perceived as facilitating successful grief work, a survey was distributed to people who had completed a grief recovery course. The results showed that emotions, cognitions, physical expressions, and behaviors all characterize grief, but that emotions are the most central component. The course brought relief and was regarded most favorably by those having at least 1 year between the grief trigger event and participation in the course. Writing a letter in which course participants express their feelings to the loss object was perceived as the most successful aspect of the course. The letter might help with grief recovery by bringing aspects that have not been dealt with into conscious awareness. 相似文献

There has been a steady trend of adopting children from other countries. Families who adopt children internationally are faced with not only the acknowledgement of the adoption but the recognition of the birth culture. Thirty four families were surveyed to assess issues regarding the relevance, frequency, and means of acknowledgement of the adoption and birth culture. Findings are reported with suggestions for adoption professionals included. 相似文献

Countertransference reactions of sleepiness and disinterest in the clinical material being presented by patients can be annoying and confusing. This paper presents a theoretical framework for understanding the author's countertransference with Borderline patients in the schizoid continuum of borderline pathology, according to a classification scheme from Meissner (1984). In the case example presented projective identification and several interpretations of its meaning are reviewed and linked with the author/therapist's experience of sleepiness in the session. The understanding and containment of these projections, as well as interpretations offered to the patient, allowed for a successful resolution to the treatment. Implications for other cases with similar character structure are discussed with emphasis on the therapists using their subjective experience of sleepiness to understand their patients. 相似文献

A TEST OF THE CURVILINEAR HYPOTHESIS WITH FACES II AND III 总被引:1,自引:0,他引:1
Previous research has not supported the validity of Olson's "curvilinear hypothesis." Convergent validity studies of the FACES I and II have indicated that the "cohesion" and "adaptability" dimensions have a linear relation with healthy family functioning. It is not clear, however, whether these findings are due to the measurement of the FACES' constructs or to the curvilinear theory. This study tested the "curvilinear hypothesis" in terms of these theoretical and measurement issues. The results indicate that FACES II and III do not adequately operation-alize the "curvilinear hyothesis." However, an item consistent with the "curvilinear hypothesis" utilizing a bipolar item response format did adequately opera-tionalize the theory. The use of a bipolar item response format is suggested in the measurement of "cohesion" and "adaptability." 相似文献

OBJECTIVE: The authors assessed the knowledge, beliefs about, and practices of vaginal douching among women attending 2 universities in the southeastern United States. PARTICIPANTS: There were 416 participants in this study; 46.9% were black and 44.5% were white. METHODS: The authors administered a 30-item questionnaire to women enrolled in health-related and social science courses at 2 southeastern universities. RESULTS: Approximately 38% of participants reported vaginal douching, mostly for hygienic reasons (70.7%). Most women first learned about douching from their mother. Douching was more common and more frequent among black women (48%) than among white women (27%). Age of first douche correlated positively with age of first sexual intercourse and age of first period. CONCLUSION: Women who had been informed not to douche by a healthcare professional were less likely to have douched within the past 6 months than were women who were not given this information. Misconceptions about douching are common and should be addressed by healthcare professionals. 相似文献

Since 1978 the federal government has implemented a variety of programs to promote the adoption of children from foster care.
A key part of these programs has been the use of subsidies to lower the cost of adopting and parenting children who have been
in foster care. Although subsidies are a key part of federal policy, there has been little empirical research on the effect
of subsidies on adoption rates. This paper uses data from the Adoption and Foster Care Analysis and Reporting System to estimate
the impact of subsidy rates on adoption rates. Subsidies to families have a positive and statistically significant effect
on adoption rates.

Evidence-based assessment in intimate partner violence (IPV) is critical to the accurate understanding of risk and to the development of interventions that increase safety. In this study standardized clients (actors) were used to train Army civilian social workers in evidence-based assessment of IPV and in the evaluation of the curriculum's effectiveness. Participation in this training curriculum increased the following: the participants' knowledge about the empirical basis for content areas explored in IPV assessment, their exploration of content critical to an IPV assessment interview, and their interviewing process skills. The results support the effectiveness of using standardized clients in IPV assessment training and evaluation. 相似文献
