Self‐regulating processes are stochastic processes whose local regularity, as measured by the pointwise Hölder exponent, is a function of amplitude. They seem to provide relevant models for various signals arising for example in geophysics or biomedicine. We propose in this work an estimator of the self‐regulating function (that is, the function relating amplitude and Hölder regularity) of the self‐regulating midpoint displacement process and study some of its properties. We prove that it is almost surely convergent and obtain a central limit theorem. Numerical simulations show that the estimator behaves well in practice. 相似文献

ABSTRACTIn this paper, I try to clarify the notions of racialisation and racial formation and how they operate in the framework of nation states like Brazil. My main argument is that these processes are always constrained by the formation of social classes and national cultural repertoires even if transnational forces are important in nurturing them. I conclude by making a preliminary effort to unravel mechanisms and institutions which allow these processes of racialisation and racial formation to form part of the daily lives of black Brazilians in the context of class-structured urban spaces. 相似文献

The paper describes the use of frequentist and Bayesian shared-parameter joint models of longitudinal measurements of prostate-specific antigen (PSA) and the risk of prostate cancer (PCa). The motivating dataset corresponds to the screening arm of the Spanish branch of the European Randomized Screening for Prostate Cancer study. The results show that PSA is highly associated with the risk of being diagnosed with PCa and that there is an age-varying effect of PSA on PCa risk. Both the frequentist and Bayesian paradigms produced very close parameter estimates and subsequent 95% confidence and credibility intervals. Dynamic estimations of disease-free probabilities obtained using Bayesian inference highlight the potential of joint models to guide personalized risk-based screening strategies. 相似文献

This study aims to assess the predictive value of two sets of variables, self-attributions, and coping behaviors, on sexually abused (SA) teenagers' functioning, while controlling for abuse-related and family variables. A total of 103 female adolescents completed self-report measures to assess their psychological functioning in terms of anxiety, depression, PTSD, sexual concerns, dissociation, anger, their self-injurious behaviors, antisocial behaviors, and drug use. After controlling for SA and family characteristics, final regression models indicate that attributions and coping behaviors explained between 22% and 39% of additional unique variance for seven out of the nine measures of adolescent functioning. Attributions and coping behaviors did not significantly explain additional variance for scores of antisocial behaviors and drug use. Personal attributions of blame for negative events were the strongest predictors of adolescents' functioning. Implications for future research and interventions are highlighted. 相似文献

As opportunities to gamble have increased during the 20th century, so has gambling research. This study used new strategies, methods, and technology to examine citation trends and the growth of knowledge in the field of gambling studies. The sample included 2,246 citations that were published between 1903 and 2003. By using multiple keywords to classify each citation into distinct topic areas, this study yielded a more comprehensive analysis than was previously available. The results reveal that gambling-related research has grown at an exponential rate. The most prevalent topics explored within gambling studies citations have been pathology, risk-taking, decision-making and addiction. Between 1999 and 2003, studies addressing epidemiology, drug abuse, comorbidity and neuroscience have become increasingly prevalent. Based on these trends and their implications, this paper provides several recommendations for both future areas of inquiry within the field of gambling studies and better classification techniques for citations within all fields of psychology. 相似文献

The Proxy Effect: Gender and Gambling Problem Trajectories of Iowa Gambling Treatment Program Participants 总被引:2,自引:2,他引:0
Nelson SE Laplante DA Labrie RA Shaffer HJ 《Journal of gambling studies / co-sponsored by the National Council on Problem Gambling and Institute for the Study of Gambling and Commercial Gaming》2006,22(2):221-240
Recent research has found that men and women who end up in gambling treatment tend to follow different trajectories to that endpoint: women generally begin gambling later in life, but progress to problems and seek treatment more quickly. With women’s prevalence rates of gambling and disordered gambling increasing, it has become important to identify the causes and consequences of these trajectory differences. The current study used a sample of 2,256 gamblers enrolled in the Iowa Gambling Treatment Program to examine the relationship of gender and other demographic, economic and health-related (i.e., psychosocial) factors to empirically-identified gambling problem trajectories. The results indicated that gender made a statistically significant contribution to the prediction of trajectory, but increased predictive accuracy by only 1–2% beyond a model with psychosocial predictors. Gender’s contribution was limited to its relationship to age of initiation; men and women’s problem progression did not differ meaningfully once age of gambling initiation was taken into account. Gender is a unique contributor to the development of gambling problems among treatment seekers, but it is only one small part of the myriad psychosocial characteristics that influence gambling problem development.

This study examines the norms and values associated with care to disabled and frail aging parents, in particular those with regard to the sharing of responsibilities for care between families and formal services, and this within three age cohorts in Quebec, Canada. It is based on a telephone interview of 1,315 people. Factor analysis yielded four factors: (1) family responsibility; (2) uncompromising family obligations; (3) acceptance of services; (4) distrust of services. Analyses of the data indicate that all three age cohorts consider that families have responsibilities for their aging family members, at the same time that they score very high on the acceptance of service scale. This article discusses these seemingly paradoxical results and their implications for aging policy. 相似文献

We report the findings from two studies that examine the association between emotional intelligence and leadership emergence in small groups. In both studies, members of groups completed measures of emotional intelligence and other individual differences prior to working on a group project. Their peers rated their leadership emergence at the conclusion of the project. Overall emotional intelligence and a number of its dimensions were associated with leadership emergence over and above cognitive intelligence, personality traits, and gender. These findings were observed when emotional intelligence was measured with an ability test but not when it was measured with a self-report scale. Among the dimensions of emotional intelligence, the ability to understand emotions was most consistently associated with leadership emergence. 相似文献

This paper proposes a comparison of the results of tax policy analysis obtained on the basis of unitary and collective representations
of the household. We first generate labour supplies consistent with the collective rationality, by use of a model calibrated
on microdata as described in Vermeulen et al. [Collective Models of Household Labor Supply with Nonconvex Budget Sets and
Nonparticipation: A Calibration Approach (2006)]. A unitary model is then estimated on these collective data and unitary and collective responses to a tax reform are compared.
We focus on the introduction of linear taxation in Germany. The exercise is replicated for other European countries and other
topical reforms. Distortions due to the use of a unitary model turn out to be important in predicting labour supply adjustments,
in the design of tax revenue neutral reforms, and in predicting a reform’s welfare implications.
