While few treatment options exist for low sexual desire and arousal, the most common sexual dysfunction in women, a growing body of research supports the efficacy of mindfulness-based approaches. The mechanisms underlying improvements, and whether they are due to mindfulness practice or other treatment components, are unclear. As a result, we designed and pilot-tested an eight-session group mindfulness-based cognitive therapy for sexuality (MBCT-S) program that includes more extensive practice of mindfulness skills and closely aligns with the evidence-based MBCT program for depression and anxiety. A total of 26 women (mean age 43.9, range 25 to 63) with a diagnosis of sexual interest/arousal disorder participated in eight weekly group sessions, before and after which they completed validated questionnaires. The majority of women attended all sessions and completed the recommended at-home mindfulness exercises. Compared to baseline, women reported significant improvements in sexual desire, overall sexual function, and sex-related distress, regardless of treatment expectations, relationship duration, or low desire duration. Depressed mood and mindfulness also significantly improved and mediated increases in sexual function. These pilot data suggest that eight-session MBCT-S is feasible and significantly improves sexual function, and provide the basis for a larger randomized-controlled trial (RCT) with a longer follow-up period. 相似文献

Movies often reflect public perceptions. The portrayal of foster care in movies provides insight regarding beliefs and attitudes children, parents, and others bring with them as they interact with the foster care system. The study focus was to identify images of foster care portrayed in 37 nondocumentary movies produced in the United States and Canada between 1921 and 2012. Using Framing Theory, an iterative review process was used to derive three dominant images presented to audiences: child entrance into foster care, a broken foster care system, and life in foster care. Movie images generally misrepresented the realities of foster care in the United States, highlighting the importance of those involved in child custody and providing a more realistic image of foster care. 相似文献

A previously known result in the econometrics literature is that when covariates of an underlying data generating process are jointly normally distributed, estimates from a nonlinear model that is misspecified as linear can be interpreted as average marginal effects. This has been shown for models with exogenous covariates and separability between covariates and errors. In this paper, we extend this identification result to a variety of more general cases, in particular for combinations of separable and nonseparable models under both exogeneity and endogeneity. So long as the underlying model belongs to one of these large classes of data generating processes, our results show that nothing else must be known about the true DGP—beyond normality of observable data, a testable assumption—in order for linear estimators to be interpretable as average marginal effects. We use simulation to explore the performance of these estimators using a misspecified linear model and show they perform well when the data are normal but can perform poorly when this is not the case. 相似文献

Summary. The concept of reliability denotes one of the most important psychometric properties of a measurement scale. Reliability refers to the capacity of the scale to discriminate between subjects in a given population. In classical test theory, it is often estimated by using the intraclass correlation coefficient based on two replicate measurements. However, the modelling framework that is used in this theory is often too narrow when applied in practical situations. Generalizability theory has extended reliability theory to a much broader framework but is confronted with some limitations when applied in a longitudinal setting. We explore how the definition of reliability can be generalized to a setting where subjects are measured repeatedly over time. On the basis of four defining properties for the concept of reliability, we propose a family of reliability measures which circumscribes the area in which reliability measures should be sought. It is shown how different members assess different aspects of the problem and that the reliability of the instrument can depend on the way that it is used. The methodology is motivated by and illustrated on data from a clinical study on schizophrenia. On the basis of this study, we estimate and compare the reliabilities of two different rating scales to evaluate the severity of the disorder. 相似文献

We demonstrate that winner selection in two prominent proportional representation voting systems is a computationally intractable
problem—implying that these systems are impractical when the assembly is large. On a different note, in settings where the
size of the assembly is constant, we show that the problem can be solved in polynomial time. 相似文献

This article explores some of the social and clinical issues facing the many different kinds of gay and lesbian families that are becoming increasingly visible in the United States. Research findings are discussed that dispel popularly held myths and stereotypes concerning these families, gays and lesbians as parents, and their children. Clinical vignettes are presented to illustrate issues often encountered in the consulting room, some unique to gay and lesbian families and some common to all families. 相似文献

On the basis of meticulous chronicles kept about the making of mutton in the Barèges valley in the French Pyrenees, this sociological study of markets examines changes in the complex relations formed between economic interests and local identities in farming. In the 1970s, pressure to standardize mutton for sale on a national market tended to efface the specific characteristics of local produce from this area in particular. In the 1980s however, producers tried to resist in various ways — direct sales in 1984, a brand name strategy in 1987 — against this loss of specificity in an undifferentiated marketplace. In 1995, a label of origin (AOC) was drawn up that not only singled out and stabilized local produce but also redefined groups of actors, ranging from producers who now focus on quality produce to consumers who increasingly look like gourmets searching for “originality”. Furthermore, this certification process led to closely linking the production and sale of produce to the promotion of a redefined local identity, which we might have imagined as being threatened owing to the expansion of business rationales. 相似文献

The articles included in this issue were originally presented at a conference on Conceptual and Methodological Developments in the Study of International Migration held at Princeton University in May 2003. The conference was jointly sponsored by the Committee on International Migration of the Social Science Research Council (SSRC), the Center for Migration and Development (CMD) at Princeton, and this journal. Its purpose was to review recent innovations in this field, both in theory and empirical research, across both sides of the Atlantic. The conference was deliberately organized as a sequel to a similar event convened by the SSRC on Sanibel Island in January 1996 in order to assess the state of international migration studies within the United States from an inter‐disciplinary perspective. A selection of articles from that conference was published as a special issue of International Migration Review (Vol. 31, No. 4, Winter), and the full set of articles was published as the Handbook of International Migration: The American Experience (Hirschman, Kasinitz and DeWind, 1999). 相似文献

The hypothesis of status inconsistency predicts greater leftism as an interaction effect of discrepant status dimensions. Inconsistent individuals are objectively low in some dimensions and subjectively insecure in those where they hold a high position. Ensuing anxiety and frustration are likely to be translated into political opposition to the status quo. Though theoretically plausible, empirical investigations of the hypothesis report mixed results. Employing data collected among a sample of 382 lower-class Chilean slum dwellers, a new test of the hypothesis is conducted. Dummy-variable regressions are employed to isolate status additive effects on leftism from inconsistency interaction effects. Neither education-occupation nor education-income discrepancies are found to produce significant changes in the dependent variable. Identical results are obtained when age is controlled for. Limitations of these findings and their theoretical implications, as they add to a growing body of research, are discussed. 相似文献

Objective: To evaluate the representation of minority groups in randomized control trials (RCTs), and the frequency with which this information is reported. Study Design: Reviewers collected data on the racial/ethnic composition of study samples from all RCTs published in six leading medical journals in 1999. Results: Of the 280 RCTs, most (204, 71.3%) provided no information on the race/ethnicity of participants. Of the 89 U.S.-based RCTs, 50 (56.1%) reported their minority distribution. Relative to other trials, those funded by the National Institute of Health (NIH) (n = 52) were more likely to report race/ethnicity data (55.8% vs. 23.7%; x2 = 20.9, p <_0.001) and to include nonwhite participants (13.5 % vs. 12.5%; x2=22.7, p<_0.001). Conclusion: Minority groups are currently under-represented in clinical trials. Information on the race and ethnicity of clinical trial participants is currently underreported in six leading medical journals. Reporting of minority group information was significantly better only in NIH funded trials, which also were more likely to include nonwhite participants. This suggests that mandatory reporting policies may have a positive effect on both reporting and representation. 相似文献
