The Savage–Dickey density ratio is a simple method for computing the Bayes factor for an equality constraint on one or more parameters of a statistical model. In regression analysis, this includes the important scenario of testing whether one or more of the covariates have an effect on the dependent variable. However, the Savage–Dickey ratio only provides the correct Bayes factor if the prior distribution of the nuisance parameters under the nested model is identical to the conditional prior under the full model given the equality constraint. This condition is violated for multiple regression models with a Jeffreys–Zellner–Siow prior, which is often used as a default prior in psychology. Besides linear regression models, the limitation of the Savage–Dickey ratio is especially relevant when analytical solutions for the Bayes factor are not available. This is the case for generalized linear models, non-linear models, or cognitive process models with regression extensions. As a remedy, the correct Bayes factor can be computed using a generalized version of the Savage–Dickey density ratio. 相似文献

The evolutionary theory of behavior dynamics is a complexity theory that instantiates the Darwinian principles of selection, reproduction, and mutation in a genetic algorithm. The algorithm is used to animate artificial organisms that behave continuously in time and can be placed in any experimental environment. The present paper is an update on the status of the theory. It includes a summary of the evidence supporting the theory, a list of the theory's untested predictions, and a discussion of how the algorithmic operations of the theory may correspond to material reality. Based on the evidence reviewed here, the evolutionary theory appears to be a strong candidate for a comprehensive theory of adaptive behavior. 相似文献

This study aimed to explore the relationships among early adolescents’ perceived parental psychological control/autonomy support, self‐trouble, and internalizing problems as well as the potential gender differences in these relationships. Multiple‐group path analysis was performed on the data collected from 1,089 adolescents in Beijing junior high schools. Results revealed that parental psychological control (autonomy support) was associated with adolescents’ more (fewer) internalizing problems, and self‐trouble acted as a mediator in these two relationships. Moreover, only the indirect relationship between parental autonomy support and internalizing problems via self‐trouble was moderated by gender, with girls showing a little stronger indirect effect than boys, and specifically, it was the relationship between autonomy support and self‐trouble that existed gender differences, with girls showing higher coefficient than boys. The relationship between parental psychological control/autonomy support and early adolescents’ internalizing problems was discussed with regard to self‐trouble and gender differences. 相似文献

ABSTRACTCognitive reflection is recognized as an important skill, which is necessary for making advantageous decisions. Even though gender differences in the Cognitive Reflection test (CRT) appear to be robust across multiple studies, little research has examined the source of the gender gap in performance. In Study 1, we tested the invariance of the scale across genders. In Study 2, we investigated the role of math anxiety, mathematical reasoning, and gender in CRT performance. The results attested the measurement equivalence of the Cognitive Reflection Test – Long (CRT- L), when administered to male and female students. Additionally, the results of the mediation analysis showed an indirect effect of gender on CRT-L performance through mathematical reasoning and math anxiety. The direct effect of gender was no longer statistically significant after accounting for the other variables. The current findings suggest that cognitive reflection is affected by numerical skills and related feelings. 相似文献

The study explored the socio-ecological (i.e. gender and geographical location) influences on the career orientations of emerging adults. The participants comprised a convenience sample of 159 black African South African university students (57% rural, 43% urban; 63% females, 37% males; mean age = 19.0, SD = 2.24). The emerging adults completed a career orientations inventory and also self-reported their demographics. We applied hierarchical regression analysis to predict the emerging adults’ career orientations from their gender and place of dwelling (geographical location) controlling for age. Results indicate that gender predicts interest in entrepreneurial creativity orientations for males rather than for females, and interest in service-oriented occupations for females compared to males. Geographical location predicted interest in entrepreneurial, general management, and service type of occupations for those from the rural rather than urban areas. Urban location predicted interest in technical and functional careers anchors. Career orientations among South African emerging adults appeared to be gendered and tied to place of geographical origin, suggesting social context socialisation influences. 相似文献

Teaching about race and racism is important in social work education, yet at times it can present perplexing experiences for some faculty members. Using the concept of intersectionality, this paper presents a narrative on my experience of teaching race and racism as a Black, female professor from the Caribbean. Examples of my pedagogical responses during these experiences are presented. 相似文献

ABSTRACTBackground: Adolescents, by their very nature and need for maturity, struggle with issues of the self and identity, while challenging the very systems that are there to support them. However, gender diverse adolescents may become detached and overwhelmed as a trans identity solidifies during this time. Bullies, blades and barricades describes the challenges, hardship and dispossession that some gender diverse adolescents face from interpersonal and intrapersonal conflicts, societal pressure and hostility.Method: This paper utilizes the current research on safety and risks affecting trans youth, the authors clinical experience of trans and gender diverse adolescents, and recommendations in the literature for professional care and support of gender diverse adolescents to identify the various ways gender diverse adolescents are negatively affected by their experiences.Results: Bullying is not limited to school or peer environments and may be present in adolescents' homes, in local communities, in professional services or from sources of information such as the media. The physical dangers gender diverse adolescents face may arise from victimization, violence or rejection, or self-harming behaviors due to negative beliefs, fear or frustration. Barriers preventing disclosure and expression of gender and/or identity may stem from negative experiences, rejection, pubertal changes, imposed limitations, dependence upon school, home or legal environments, or other spheres of influence.Discussion: Affirmative approaches, individual focus, recognition of family dynamics, inclusion of significant others, advocacy in school and local community environments as well as professional training are the most commonly recommended interventions. This paper provides an inclusive review of the myriad of challenges confronting gender diverse adolescents including often unrecognized forms of pressure, oppression and restrictions. This paper aims to support clinicians by contextualizing the adversity that gender diverse adolescents face and offers strategies for engagement and intervention. 相似文献

ABSTRACTBackground: Mainstream media is increasingly reporting on the relationships between Catholic and trans identities in parochial schools, particularly with regard to gendered washroom use. With greater numbers of trans youth coming out at younger ages, significant educational policy changes are being considered around how Catholic schools can or should include trans youth.Method: This study applies trans and queer theologies to Critical Discourse Analysis (CDA) in investigating the Wilson case, which was the first known instance of a Catholic school including some affirming policy provisions for trans youth. The authors additionally collected and coded 12 news articles from a variety of platforms to discern and discuss the theological arguments in the public square against more fulsome trans student inclusion in Catholic schools.Results: The authors found two related theological arguments against full inclusion, namely the notion that (1) Gender is God-given and therefore cannot be chosen or changed, and (2) That transgressive bodies are not sacred parts of the divine gender plan.Conclusion: Trans theology allowed the authors to disrupt both of the theological claims advanced by the Catholic educators quoted in the Wilson case. This created rich, imaginative space in which to reconsider the relationships between Catholic and trans identities, namely by not arranging them in a binary. Significance for policy-making in parochial schools is discussed. 相似文献

Collecting samples is a challenging task for face recognition, especially for some real-world applications such as law enhancement and ID card identification, where there is usually single sample per person (SSPS) used to train a face recognition system. To extract discriminative features from the small size samples, in this paper we propose virtual samples via bidirectional feature selection with global and local structure preservation (VS-BFS-GL) to augment the number of training samples. In VS-BFS-GL, bidirectional feature selection is developed, which introduces L2,1 norm to explore the face variations from both horizontal and vertical directions. Further, to include more variations in the virtual images, the global structure information and sample-specified local structure information of the SSPP training set are considered. By integrating bidirectional feature selection, global and local structure, the limited training samples are fully utilized and more knowledge are mined. To further improve the effectiveness of VS-BFS-GL, an auxiliary database containing different face variations can be used to explore the local structure information. We extensively evaluated the proposed approach on AR and FERET database. The promising recognition results demonstrate that VS-BFS-GL is robust to expression, pose and partial occlusion variations in the faces. 相似文献
