Modelling Trends in Ordered Correspondence Analysis Using Orthogonal Polynomials

The core of the paper consists of the treatment of two special decompositions for correspondence analysis of two-way ordered contingency tables: the bivariate moment decomposition and the hybrid decomposition, both using orthogonal polynomials rather than the commonly used singular vectors. To this end, we will detail and explain the basic characteristics of a particular set of orthogonal polynomials, called Emerson polynomials. It is shown that such polynomials, when used as bases for the row and/or column spaces, can enhance the interpretations via linear, quadratic and higher-order moments of the ordered categories. To aid such interpretations, we propose a new type of graphical display—the polynomial biplot.     

Assessing the effect of a Cognitive Behaviour Therapy (CBT)-based workshop on work-related rumination,fatigue, and sleep

This quasi-experimental longitudinal study assessed the effect of a one-day Cognitive Behaviour Therapy (CBT)-based workshop on work-related rumination, chronic fatigue, and sleep quality. We hypothesized that participants who attended the workshop would report lower levels of affective work-related rumination, chronic fatigue, and improved sleep quality, at follow-up, 6 months after workshop completion. Two hundred and twenty-seven participants took part in the study, with 102 participants attending a one-day workshop delivered in their workplace. Participants completed an online questionnaire at two time-points, with follow-up occurring 6 months after initial survey completion. Results showed that participants who took part in the CBT workshop reported significantly lower levels of affective rumination (p = .03) and chronic fatigue (p = .003), at follow-up in comparison with individuals who did not attend the workshop; however, there were no significant differences between the groups in self-reported sleep quality (p = .06). A combination of more effective recovery both at work and outside of work may explain the reductions in both affective rumination and fatigue over time. This study adds to the recovery from work literature by providing initial support for a one-day CBT-based workshop delivered in the workplace.     

The experience of feeling fat for women with anorexia nervosa: An interpretative phenomenological analysis

Feeling fat has been implicated as a maintenance factor in anorexia nervosa (AN), despite limited research into the experience. This study expanded the literature by exploring the lived experience of feeling fat for women with a diagnosis of AN. Seven women participated in this study and data was collected through semi-structured interviews. Interpretive Phenomenological Analysis (IPA) was employed to explore the participants’ experience of ‘feeling fat’ and its relevance for clinical treatment. Four main themes emerged from the data: ‘negative sense of self’, ‘feeling out of control’, ‘coping with feeling fat’, and ‘making sense of feeling fat is complex’. These results highlight feeling fat as a significant experience and maintenance factor for women with a diagnosis of AN. Implications for addressing feeling fat within psychological therapy are explored.     

Differences in the neurocognitive profiles of professional and semi-professional male South African rugby union players

This study investigated possible cognitive functioning profile differences between professional and semi-professional rugby players. Seventy-nine male rugby union players (professional = 55, semi-professional = 24; age range = 19–37 years) participated in the study. The players completed a battery of neuropsychological functioning tests covering the following domains: memory tasks, attention and behavioural tasks, sensory-motor tasks, executive functioning tasks, verbal tasks, and emotion identification tasks. Results following Fisher’s exact test comparisons revealed no significant group differences in the cognitive functioning profiles.     

An Overview of Primary Care Family Psychology

This paper describes the application of family psychology to the primary care setting—in service, education and training, and scholarship. Primary care family psychology integrates family systems with biopsychosocial theory, yielding an approach that is uniquely suited to the generalist demands of primary care. This approach attends especially to the effects of relationships on health and healthcare, using the family as a potential resource to the patient just as the healthcare team is a resource to the clinician. Training opportunities in primary care family psychology are growing. The University of Rochester School of Medicine and Dentistry fellowship is described as an example, with core primary care family psychology training in four different clinical sites: Family Medicine, Internal Medicine, Pediatrics, and Obstetrics/Gynecology. Susan H. McDaniel is Professor of Psychiatry & Family Medicine, Director of Family Programs & the Wynne Center for Family Research in Psychiatry, and Associate Chair of Family Medicine, University of Rochester School of Medicine and Dentistry, Rochester, New York. Dr McDaniel also directs the Primary Care Family Psychology Fellowship. Picter LeRoux is Associate Professor of Psychiatry & Pediatrics, and Director of the Family Therapy Training Program in Psychiatry, University of Rochester School Medicine and Dentistry, Rochester, New York. Dr. LeRoux also heads the Pediatric Track of the Primary Care Family Psychology Fellowship.     

The multicultural personality questionnaire: a multidimensional instrument of multicultural effectiveness

In today's global business environment, executive work is becoming more international in orientation. Several skills and traits may underlie executive success in an international environment. The Multicultural Personality Questionnaire was developed as a multidimensional instrument aimed at measuring multicultural effectiveness. The questionnaire has scales for Cultural Empathy, Openmindedness, Emotional Stability, Orientation to Action, Adventurousness/Curiosity, Flexibility, and Extraversion. In a study among a student sample (N =257) the reliability and validity of the inventory were examined. The internal consistencies of the developed scales were high, with the exception of Openmindedness and Flexibility. On the basis of factor analysis and the pattern of intercorrelations four reliable higher‐level dimensions were distinguished: ‘Openness’, ‘Emotional Stability’, ‘Social Initiative and Flexibility’. The correlations between these dimensions and related instruments were in the expected direction. Moreover, the data supported the predictive value of the instrument of multicultural activity and its incremental value above the Big Five in predicting international orientation and aspiration of an international career. The Multicultural Personality Questionnaire may be used as an instrument for the selection of expatriates or as a diagnostic tool for assessing further training needs.

Concurrent schedules: Maximization versus reinforcement of changeover behaviour

Pigeons responded on concurrent variable-interval 180-sec variable-interval 36-sec schedules during Conditions 1 and 3 of Experiment 1. Condition 2 arranged variable-interval 60-sec schedules for both response alternatives. The schedule assigned to the alternative that was associated with the variable-interval 36-sec schedule in Conditions 1 and 3 operated only when the subject responded on that alternative. The proportion of time spent responding on the alternative with the conventional variable-interval 60-sec schedule increased during Condition 2, but exclusive choice of that alternative did not develop. This result is inconsistent with maximization of the overall reinforcement rate and with maximization of the momentary probability of reinforcement (momentary maximizing). Increasing time proportions were also found in Experiment 2, which arranged similar conditions, except that reinforcement was provided on a variable-time basis. The time proportions were close to the momentary maximizing prediction in Experiment 2. The results of both experiments can be explained if it is assumed that time allocation is controlled by delayed reinforcement of changeovers between alternatives.     

Getting a foothold: Male immigrant employment integration and structural change in Sweden, 1970–1995

In this article the employment performance of native and foreign-born men in Sweden is examined in the period 1970–1995. Using longitudinal data, the relative chance of obtaining first employment during the first two years in the labour market for natives and various immigrant groups is estimated. The main hypothesis tested is to what kind and what degree structural changes in the labour market affect the employment performance of various immigrant groups. The results show that since the middle of the 1980s, there has been a change in employment performance among immigrant men, who are perceived to be culturally and linguistically less close to Sweden. It is during this period that structural changes in the labour market occurred, in particular the organizational and technological changes that demand more communicativeand interpersonal skills, that is, Sweden-specific skills.
