This paper establishes a remarkable result regarding Palm distributions for a log Gaussian Cox process: the reduced Palm distribution for a log Gaussian Cox process is itself a log Gaussian Cox process that only differs from the original log Gaussian Cox process in the intensity function. This new result is used to study functional summaries for log Gaussian Cox processes. 相似文献

Estimation and Inference Procedures for Semiparametric Distribution Models with Varying Linear‐Index 下载免费PDF全文
More flexible semiparametric linear‐index regression models are proposed to describe the conditional distribution. Such a model formulation captures varying effects of covariates over the support of a response variable in distribution, offers an alternative perspective on dimension reduction and covers a lot of widely used parametric and semiparameteric regression models. A feasible pseudo likelihood approach, accompanied with a simple and easily implemented algorithm, is further developed for the mixed case with both varying and invariant coefficients. By justifying some theoretical properties on Banach spaces, the uniform consistency and asymptotic Gaussian process of the proposed estimator are also established in this article. In addition, under the monotonicity of distribution in linear‐index, we develop an alternative approach based on maximizing a varying accuracy measure. By virtue of the asymptotic recursion relation for the estimators, some of the achievements in this direction include showing the convergence of the iterative computation procedure and establishing the large sample properties of the resulting estimator. It is noticeable that our theoretical framework is very helpful in constructing confidence bands for the parameters of interest and tests for the hypotheses of various qualitative structures in distribution. Generally, the developed estimation and inference procedures perform quite satisfactorily in the conducted simulations and are demonstrated to be useful in reanalysing data from the Boston house price study and the World Values Survey. 相似文献

The randomized response technique (RRT) is an important tool, commonly used to avoid biased answers in survey on sensitive issues by preserving the respondents’ privacy. In this paper, we introduce a data collection method for survey on sensitive issues combining both the unrelated-question RRT and the direct question design. The direct questioning method is utilized to obtain responses to a non sensitive question that is related to the innocuous question from the unrelated-question RRT. These responses serve as additional information that can be used to improve the estimation of the prevalence of the sensitive behavior. Furthermore, we propose two new methods for the estimation of the proportion of respondents possessing the sensitive attribute under a missing data setup. More specifically, we develop the weighted estimator and the weighted conditional likelihood estimator. The performances of our estimators are studied numerically and compared with that of an existing one. Both proposed estimators are more efficient than the Greenberg's estimator. We illustrate our methods using real data from a survey study on illegal use of cable TV service in Taiwan. 相似文献

Cultural Attunement in Therapy With Mexican‐Heritage Couples: A Grounded Theory Analysis of Client and Therapist Experience 下载免费PDF全文
Marco A. Elias‐Juarez Carmen Knudson‐Martin 《Journal of marital and family therapy》2017,43(1):100-114
There is a need for culturally attuned approaches for couple therapy with Mexican/Mexican‐Americans. This qualitative grounded theory study utilized interviews with 11 client couples of Mexican heritage and 14 marital and family therapists to shed light on how Latino and non‐Latino therapists co‐construct positive experiences of cultural attunement with Mexican and Mexican‐American couple clients. Analysis identified a model of cultural connection through personal engagement with four interrelated phases: (a) mutual invitation, (b) shared engagement, (c) expanding personal connection, and (d) creating cultural connections. Clients in this study valued professionalism and expertise of the therapist, but felt attuned to and respected when therapists demonstrated humility, shared personal stories and emotion, and engaged in a collaborative process. 相似文献

It's About Time! Examining Received Dosage and Program Duration as Predictors of Change Among Non‐Distressed and Distressed Married Couple and Relationship Education Participants 下载免费PDF全文

Although Couple and Relationship Education (CRE) programs were intended to be preventive in nature, an emerging reality is that relationally distressed couples are attending programs. This has raised questions about both its general usefulness and what is known regarding predictors of change in CRE for distressed couples particularly. Previous work has identified dosage and duration as important moderators of changes, and there are myriad program contexts offered, highlighting the need to examine these among distressed couples. This study utilized a sample of community CRE participants and examined received dosage and program duration as predictors of change. Comparing results for distressed and non‐distressed participants, we found several group differences. Findings suggest that it is important to consider distress level and time spent in programs when placing participants. In addition, research should continue to examine these groups separately (or comparatively) to find out what works for whom. 相似文献

Marie‐Laurence Flahaux 《The International migration review》2017,51(4):868-892
This study questions the role of migration policy changes in France, Italy, and Spain for return migration to Senegal, by analyzing biographic data from the Migration between Africa and Europe (MAFE‐Senegal) survey and the contextual data of the Determinants of International Migration (DEMIG) VISA and DEMIG POLICY databases that cover major changes in migration policies in these destination countries for the different categories of migrants. Event history logistic regressions reveal that Senegalese migrants are less likely to return when the entry restrictions have become tighter. This result suggests that the decision to return depends on the possibility of migrating again after the return, which is crucial for both theory and policy regarding Western democracies' attempts to regulate migration. 相似文献

An internationally recognised body of knowledge is both possible and necessary for the future success and professionalisation of public relations. Through extensive content analysis of 31 credential schemes, education frameworks, and scholarly articles produced across six continents, the Global Alliance for Public Relations and Communications Management has developed a foundational list of knowledge, skills, abilities and behaviours (KSABs), which entry and mid/senior-level practitioners across the world should possess. This study and list of KSABs is laying the foundation for development of an internationally accepted framework which professional associations and academic institutions across the world will be able to use to benchmark professional credentials and curriculum outcomes. 相似文献

Demands and Devotion: Cultural Meanings of Work and Overload Among Women Researchers and Professionals in Science and Technology Industries 下载免费PDF全文
How do cultural meanings influence how people experience work‐life demands? Much research, especially quantitative research, on the effects of structural work and family conditions does not account for employees’ cultural beliefs about the meaning of work in their lives. This article uses unique survey data to investigate the effects of employee embrace of elements of the “work devotion schema”—a cultural model that valorizes intense career commitment and organizational dedication—on their sense of “overload,” an experience that includes feeling exhausted and overloaded by all one's roles, net of actual hours on the paid job and family responsibilities. We argue that by cognitively, morally, and emotionally framing work as a valued end, the work devotion schema reduces feelings of overload. Using a case of senior women researchers and professional service providers in science and technology industries, we find that those who embrace work devotion feel less overloaded than those who reject it, net of work and family conditions. However, this effect is curtailed for mothers of young and school‐aged children. We end by discussing implications for flexibility stigma and gender inequality. 相似文献

This study extends Flores et al.'s ( 2006 ) 36‐year analysis of racial/ethnic minority (REM) career research to identify recent trends in choice of topics and leading individual and institutional contributors. The authors identified 166 articles on REM career research published from 2005 to 2015 in the Journal of Vocational Behavior, The Career Development Quarterly, the Journal of Career Assessment, and the Journal of Career Development. Of these studies, 92% were empirical, with more than three quarters of these using quantitative rather than qualitative methodology. Most frequently, the empirical studies (n = 153) were based on samples of high school (30.7%) or undergraduate (34.6%) students. The authors discuss the implications of their findings and suggest ways to expand REM career research in the future. 相似文献

“Yes,I Can”: Testing an Intervention to Increase Middle School Students’ College and Career Self‐Efficacy 下载免费PDF全文
Karin Glessner Amanda J. Rockinson‐Szapkiw Mercedes L. Lopez 《The Career development quarterly》2017,65(4):315-325
Middle school is the appropriate time for students to begin exploring careers and improving self‐efficacy; however, empirically supported career and college readiness interventions for U.S. middle school students are limited. Examining the effect of an intervention that combined a virtual experience and a local college visit on middle school students (99 girls, 74 boys), the authors found that participating students had higher levels of college and career self‐efficacy than did nonparticipating students. The study shows that a workshop of the online Florida CHOICES program coupled with a campus visit increased middle school student career and college self‐efficacy. Future research should include longitudinal studies and use of diverse populations to improve generalizability of study results. 相似文献
