Multivariate process dispersion monitoring without subgrouping

The memory-type adaptive and non-adaptive control charts are among the best control charts for detecting small-to-moderate changes in the process parameter(s). In this paper, we propose the Crosier CUSUM (CCUSUM), EWMA, adaptive CCUSUM (ACCUSUM) and adaptive EWMA (AEWMA) charts for efficiently monitoring the changes in the covariance matrix of a multivariate normal process without subgrouping. Using extensive Monte Carlo simulations, the length characteristics of these control charts are computed. It turns out that the ACCUSUM and AEWMA charts perform uniformly and substantially better than the CCUSUM and EWMA charts when detecting a range of shift sizes in the covariance matrix. Moreover, the AEWMA chart outperforms the ACCUSUM chart. A real dataset is used to explain the implementation of the proposed control charts.     

The Effect of Occupational Sex Composition on the Gender Gap in Workplace Authority

This article compares women and men's attainment of workplace authority in female-dominated, mixed, and male-dominated occupations. It is based on a representative mobility study of Jewish women in the Israeli labor force conducted in 1991–1992. Two sets of hypotheses are offered based on two competing theories. The first theory predicts that in female occupations women have more influence and mutual support than in male occupations, and, hence, they will have more access to authority. The opposing perspective argues that in male-dominated occupations the competition between women and men is weaker, and therefore men have a smaller incentive to discriminate against women. Our findings support the second argument. The gender gap in authority is larger in female-dominated occupations, and women have the highest chances to have authority when they work in male occupations; men have similar chances, no matter in which type of occupation they are employed.     

Bayes linear analysis for graphical models: The geometric approach to local computation and interpretive graphics

This paper concerns the geometric treatment of graphical models using Bayes linear methods. We introduce Bayes linear separation as a second order generalised conditional independence relation, and Bayes linear graphical models are constructed using this property. A system of interpretive and diagnostic shadings are given, which summarise the analysis over the associated moral graph. Principles of local computation are outlined for the graphical models, and an algorithm for implementing such computation over the junction tree is described. The approach is illustrated with two examples. The first concerns sales forecasting using a multivariate dynamic linear model. The second concerns inference for the error variance matrices of the model for sales, and illustrates the generality of our geometric approach by treating the matrices directly as random objects. The examples are implemented using a freely available set of object-oriented programming tools for Bayes linear local computation and graphical diagnostic display.     

Reducing attitudes of prejudice and discrimination through literature: a quasi-experiment on the upper key-stage 2 students of the British schools in Karachi,Pakistan

This study aims to explore the efficacy of literature relating to Anne Frank to reduce children’s attitudes of prejudice and discrimination with respect to specific dimensions, including ethnicity and race, religion and gender. A quasi-experiment was employed with pre-post control design. The sample consisted of 100 students of the upper key-stage 2 (UKS2) level, recruited from the two British schools in Karachi. These schools represented an Experimental Group (EG) and a matched Comparison Group (CG). A research instrument titled ‘Muggles world of differences’ (MWD) was developed and validated. It was administered on CG and EG, both before and after intervention. The intervention plan ‘Reading of Young Anne’s Literature’ (ROYAL) was developed based on selected readings from Anne Frank related literature (AFL). Intervention was provided to EG, while CG studied similar concepts using a more standard method. Results of the pretest revealed a high level of prejudice and discrimination in both the EG and CG, with no significant difference (p > 0.05) in the overall scores, as well as in the specific content domains. However, the post-test of the two groups revealed that the students in the EG had outperformed their CG counterparts in overall MWD scores, as well as in specific content domains. The difference was found to be significant (p < 0.05) with the large effect size (r = ?0.63). Results support the efficacy of teaching Anne Frank related literature in reducing attitudes of prejudice and discrimination.     

‘Occupation Children’ in Germany after World War II — Problems and Coping Strategies

The article focuses on the autobiographical memories of people born in Germany after the Second World War, whose mothers were local women and whose fathers were members of the allied forces. Based on the analysis of narrative interviews, we ask how these people experienced their growing up and their sociocultural environment in the post‐war era, and what kind of coping strategies they developed to deal with adverse living conditions.     

Discrimination,mental health,and body image among transgender and gender-non-binary individuals: Constructing a multiple mediational path model

The purpose of the current study was to examine the relationships among discrimination, mental health, and body image in a national sample of transgender adults. Participants (N = 78) identified as transgender, genderqueer, or other gender-non-binary identities and were recruited via a national online survey. Harassment/rejection, work/school, and other discrimination explained 10.4% of the variance in body appreciation, while satisfaction with life, anxiety, self-esteem, and depression explained 60.7%. Within these models, harassment/rejection was inversely associated with body appreciation, while self-esteem and satisfaction with life were positively associated. A series of path models moving from a measurement model to a more parsimonious and excellent-fitting model found that the effect of harassment/rejection on body appreciation was fully mediated by self-esteem and satisfaction with life, resulting in a multiple mediation.     

How national identification matters: the development of European identification among established ethnic minority groups

Based upon the data from qualitative studies of eight national minorities between the Baltic and the Danube, this article investigates the formation of European identification among members of the minority groups representing ‘split nations’ along the new eastern borders of the enlarged EU. The analysis reveals mechanisms of the formation of supranational identification by focusing on the relationships between subnational, national and European identifications to ascertain the degree of interconnectedness of these identification levels. These relationships are examined in the context of the potential impact of perceived ethnic conflict and utilitarian expectations of socio-economic and cultural gains from the process of European integration.     

Child labour measurement: Whom should we ask?

Funding decisions to support vulnerable children are tied to child labour statistics, hence the importance of an accurate measurement. The author analyses whether the type of respondent plays an important role in explaining variations in child labour statistics. Using data from two sites in Tanzania, the analysis shows that “whom we ask” matters considerably when estimating the prevalence of child labour. The results suggest that prevalence increases by approximately 35 to 65 per cent when using child self‐reports rather than proxy reports. This bias affects 14 to 31 per cent of the sample, depending on the indicator. Discrepancies decrease as the child ages and increase if proxy attitudes demonstrate opposition to child labour.     

Unreasonable adjustments: the additional unpaid labour of academics with disabilities

Abstract

Two recent contributions to this section have drawn attention to the barriers which academics with disabilities have to navigate in academia where ableism “is endemic” (Brown and Leigh, 2018 Brown, N & Leigh, J (2018) Abelism in academia? Where are the disabled and ill academics. Disability & Society, 33 (6): 985–989.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]: 4). Hannam-Swain (2018 Hannam-Swain, S (2018) The additional labour of a disabled PhD student. Disability & Society, 33 (1): 138–142.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) highlighted the additional intellectual, emotional and physical labour required of her as a disabled PhD student, and Brown and Leigh (2018 Brown, N & Leigh, J (2018) Abelism in academia? Where are the disabled and ill academics. Disability & Society, 33 (6): 985–989.[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]) queried “where are all the disabled and ill academics?” However, Brown and Leigh primarily focus on those with invisible “conditions” and the dilemmas raised by disclosure in a context where such conditions negate academic status and credibility. In contrast, since my “disability” is visible, I do not share the dilemma/“luxury” of secrecy. My presence announces my status before me, and this negates my personhood altogether in academic settings. It also places a burden of additional unpaid labour upon me which has significant mental health and career impacts as well as violating principles of equality.
