Over the past decade, a contentious debate regarding delayed memories of childhood sexual abuse (CSA) has existed. In order to address this debate, 240 female participants completed questions about CSA, the Dissociative Experience Scale (Bernstein & Putnam, 1986), Perceived Emotional Closeness with Perpetrator Scale (Schultz, Passmore, & Yoder, 2000), and the Gudjonsson Suggestibility Scale 2 (GSS 2) (Gudjonsson, 1987). Eighty-two (36%) reported CSA and 37% of these indicated memory disturbances for the CSA. Participants reporting memory disturbances also reported significantly higher numbers of perpetrators, chemical abuse in their families, and closer relationships with the perpetrator(s) than participants reporting no memory disturbances. Implications for clinicians working with clients reporting CSA are discussed.  相似文献

Some policy makers and policy analysts have proposed that Social Security should be privatized to enable participants to achieve higher returns through investment in the stock market. How well individual retirees would fare financially under a privatized system largely depends on their decision to invest in the equity market, rather than in other types of investment vehicles. For that reason, it is important to investigate the degree to which minority people are currently investing in this market. This article presents the findings of a study that compared the investment behavior of black and Hispanic people aged 51 to 61 with the investment behavior of their white counterparts. The major findings indicate that black and Hispanic people: (a) are less likely to invest in the equity market than are white people, and (b) tend to invest smaller percentages of their assets in the equity market. Implications for policy are discussed.  相似文献

The relative standings of four ethnic groups - Muslim Palestinians, Christian Palestinians, Asian-African Jews, European Jews -were compared, using mobility data from 1974 and 1991. The findings show that despite the lack of government support and the prevalence of inexorable discrimination against Israeli Palestinians, they have narrowed the gap with Asian-African Jews in both education and occupational prestige. This finding demonstrates that ideological and political hegemony is not always effective in improving the socio-economic standing of preferred minorities (Asian-African Jews), and that social and economic structures may counterbalance the anti-Palestinian nationalist ideology. The analysis suggests that residential and educational segregation of Palestinians protects them from direct competition with European Jews, whereas Asian-African Jews have to compete with this dominant group in schools, as well as in the labour market.  相似文献

Under appropriate long range dependence conditions, the point process of exceedances of a stationary sequence weakly converges to a homogeneous compound Poisson point process. This limiting point process can be characterized by the extremal index and the cluster-size probabilities. In this paper we address the problem of estimating these quantities and we consider the intervals estimators introduced in Ferro and Segers [2003. Inference for clusters of extreme values. J. Roy. Statist. Soc. Ser. B 545–556] and in Ferro [2004. Statistical methods for clusters of extreme values. Ph.D. Thesis, Lancaster University]. We establish asymptotic weak convergence to Gaussian random variables and we give their asymptotic variance.  相似文献

The multidimensionality of money was investigated, using exploratory factor analysis (EFA). The respondents, 290 college students from Korea, Japan, and the United States, were administered a survey, which included socio-demographic questions, and Furnham's (1984) Money Beliefs and Behaviors (MBBS) Scale. Through a series of principal components analyses, a three-factor model with 10 MBBS items was identified. The three factors, Power, Security, and Financial Modesty accounted for 53.6% of the variance. The findings have implications for college students and financial management practitioners.  相似文献

This paper studies the effects of learning and forgetting on the production lot size problem with infinite and finite planning horizons. It is assumed that the determination of the economic manufactured quantity (EMQ) in the succeeding production run is dependent on: (1) the maximum inventory accumulated prior to interruption; (2) the length of the interruption period which incurs total forgetting; and (3) the level of experience in equivalent units remembered at the start-up of the next production run. The optimum operating inventory doctrines is obtained by trading off procurement cost per unit time and the inventory carrying cost per unit time, so that their sum will be a minimum. A numerical example is presented to demonstrate the application of learning and forgetting to the determination of the EMQ.  相似文献

We consider the piecewise proportional hazards (PWPH) model with interval-censored (IC) relapse times under the distribution-free set-up. The partial likelihood approach is not applicable for IC data, and the generalized likelihood approach has not been studied in the literature. It turns out that under the PWPH model with IC data, the semi-parametric MLE (SMLE) of the covariate effect under the standard generalized likelihood may not be unique and may not be consistent. In fact, the parameter under the PWPH model with IC data is not identifiable unless the identifiability assumption is imposed. We propose a modification to the likelihood function so that its SMLE is unique. Under the identifiability assumption, our simulation study suggests that the SMLE is consistent. We apply the method to our cancer relapse time data and conclude that the bone marrow micrometastasis does not have a significant prognostic factor.  相似文献
