A multistage ranking model

In this paper, we propose a (n–1)² parameter, multistage ranking model, which represents a generalization of Luce's model. We propose then×n item-rank relative frequency matrix (p-matrix) as a device for summarizing a set of rankings. As an alternative to the traditional maximum likelihood estimation, for the proposed model we suggest a method which estimates the parameters from thep-matrix. An illustrative numerical example is given. The proposed model and its differences from Luce's model are briefly discussed. We also show some specialp-matrix patterns possessed by the Thurstonian models and distance-based models.     

Bayesian analysis of order-statistics models for ranking data

In this paper, a class of probability models for ranking data, the order-statistics models, is investigated. We extend the usual normal order-statistics model into one where the underlying random variables follow a multivariate normal distribution. Bayesian approach and the Gibbs sampling technique are used for parameter estimation. In addition, methods to assess the adequacy of model fit are introduced. Robustness of the model is studied by considering a multivariate-t distribution. The proposed method is applied to analyze the presidential election data of the American Psychological Association (APA).The author is grateful to K. Lam, K.F.

Racial Justice for the Windrush Generation in Great Britain

This article argues that the experience of the “Windrush generation,” Black Caribbean post–Second World War migrants to the UK, has been one of constant struggle for racial justice. Living in Britain has been undertaken against the backdrop of a Mission Christianity that has exuded a distinct anti-Blackness in its relationship with Black bodies across four centuries. This particular dynamic of “Christian Britain” has created a framework that has helped to shape the agency of Black bodies, essentially marking them as “less than.” This theo-cultural framework has led to a racialized existence for Black British people of the Windrush generation and their descendants. The Christianity that has emerged from the Black Caribbean experience constantly challenges White British Christianity to express an anti-racist and more inclusive model of liberative praxis. This paper is written against the backdrop of the Brexit furore in Britain and the xenophobia and rise in racist attacks that have underpinned the rise in White British nationalism.     

Predictors of stress generation in Turkish young adults: The role of rumination and excessive reassurance seeking

The stress generation model posits that not only stressful life-events predict depressive symptoms, but also depressive-prone individuals think and behave in ways that make them more vulnerable to experience life-stress. Evidence has supported the bi-directional relationship between stress and depressive symptoms, and there has been an attempt in identifying vulnerability factors for stress generation. Yet, there is a need for studies focusing on multiple risk factors and a replication of findings in non-Western samples. The aim of the present study was to examine the role of rumination and excessive reassurance seeking (ERS) in stress generation in a sample of Turkish young adults. A sample of 318 Turkish college students reported on their rumination, ERS, intensity of stressful life-events and depressive symptoms. A subsample of 162 participants also completed a measure of life-events 5 months later. Cross-sectional results showed that rumination and ERS contribute to life-stress over and above depressive symptoms and gender. Mediational analyses indicated that ERS does not mediate the relationship between rumination and life-stress at 5 months. Rather, rumination fully mediated the relationship between ERS and future life-stress. Results provide evidence for stress generation, and highlight the interconnection between rumination and ERS.     

A Social Network Analysis of Friendship and Spiritual Support in a Religious Congregation

Religious congregations are social settings where people gather together in community to pursue the sacred (Pargament, 2008). Such settings are important to understand as they provide a context for individuals to develop relationships, share ideas and resources, and connect individuals to larger society (Todd, 2017a). Yet, research to date has not deeply examined the inherently relational nature of religious congregations. Thus, in this study, we used social settings theory (Seidman, 2012; Tseng & Seidman, 2007) to develop and test hypotheses about relationships within one Christian religious congregation. In particular, we used social network analysis to test hypotheses about relational activity, popularity, and homophily for friendship and spiritual support types of relational links. Our findings demonstrate how relational patterns may be linked to participation in congregational activities, occupying a leadership role, a sense of community and spiritual satisfaction, stratification, socialization, and spiritual support. Overall, this advances theory and research on the relational aspects of religious congregations, and more broadly to the literature on social settings. Limitations, directions for future research, and implications for theory and religious congregations also are discussed.     

Comparison of hemispheric activation during mental word and rhyme generation using transcranial Doppler sonography

The Wada test is at present the method of choice for preoperative assessment of patients who require surgery close to cortical language areas. It is, however, an invasive test with an attached morbidity risk. By now, an alternative to the Wada test is to combine a lexical word generation paradigm with non-invasive imaging techniques. However, results of this approach are still not in complete agreement with the findings of the Wada test (r = .92; Knecht, Deppe, Ebner et al., 1998). We attempted to obtain a more distinct language lateralization with the development of a phonological rhyme generation paradigm based on pseudoword stimuli. To examine the predictive value of both paradigms we performed simultaneous bilateral functional transcranial Doppler ultrasonography on 19 right-handed male native German subjects. The rhyme generation condition produced a significantly stronger lateralization to the supposed hemisphere of language dominance than the classical word generation condition. The observed differences suggest that the rhyme generation paradigm is more robust in detecting hemispheric language dominance than other neuropsychological paradigms and might be most valuable for preoperative assessment of cortical language areas.     

Random effects diagonal metric multidimensional scaling models

By assuming a distribution for the subject weights in a diagonal metric (INDSCAL) multidimensional scaling model, the subject weights become random effects. Including random effects in multidimensional scaling models offers several advantages over traditional diagonal metric models such as those fitted by the INDSCAL, ALSCAL, and other multidimensional scaling programs. Unlike traditional models, the number of parameters does not increase with the number of subjects, and, because the distribution of the subject weights is modeled, the construction of linear models of the subject weights and the testing of those models is immediate. Here we define a random effects diagonal metric multidimensional scaling model, give computational algorithms, describe our experiences with these algorithms, and provide an example illustrating the use of the model and algorithms.We would like to thank J. Douglas Carroll for early consultation of this research, and Robert I. Jennrich for commenting on an earlier draft of this paper and for help on the computational algorithms. James O.
