Steps in the Right Direction,Against the Odds,An Evaluation of a Community‐Based Programme Aiming to Reduce Inactivity and Improve Health and Morale in Overweight and Obese School‐Age Children

The study describes an evaluation of a 48‐week physical activity and nutritional education programme for overweight/obese school‐age children using quantitative and qualitative methods. The majority of participants were obese or severely obese when enrolled, and while some improvements in body mass index, self‐esteem and engagement in a range of physical activities were noted, difficulties in evaluating a complex community‐based intervention were highlighted. Children, parents and health professionals described a range of benefits from attending the programme but more intensive services are likely to be needed for the most seriously obese children and for those families resisting intervention.

This article explores whether it is possible to understand the perspectives of people with whom we find it difficult or impossible to empathise, because their moral and political views are very different to our own. Focusing on our dilemmas in carrying out qualitative research with conservative evangelicals and anti‐abortion activists, we take issue with the assumption that understanding is connected with the presence of rapport and empathy in research interviews. This article argues instead that a reflexive approach, which considers researchers’ orientations towards their subject and their respondents and their emotional journeys through the research process, will enable more comprehensive interpretation of our research material.     

The present status of confidence interval estimation on variance components in balanced and unbalanced random models

Much research has been conducted to develop confidence Intervals on linear combinations and ratios of variance components in balanced and unbalanced random models.This paper first presents confidence intervals on functions of variance components in balanced designs.These results assume that classical analysis of variance sums of squares are independent and have exact scaled chi-squared distributions.In unbalanced designs, either one or both of these assumptions are violated, and modifications to the balanced model intervals are required.We report results of some recent work that examines various modifications for some particular unbalanced designs.     

On the reciprocity of connections in weighted and unweighted networks

Bivariate Bernoulli and bivariate geometric distributions are proposed to model reciprocity in weighted and unweighted networks. Sampling properties of commonly used reciprocity measures are studied, under both presence and absence of reciprocity. Extensions to situations where link parameters depend on outgoing and incoming nodes are investigated. Results are illustrated with a data set, on 50 anesthesia providers at a hospital, that describes the number of times an anesthesia provider starting an operation transfers his/her responsibilities to another anesthesia provider.     

A statistical measure of internal consistency

A test for homogeneity of several populations against the simple tree alternative is proposed when the observations in various groups are subject to the same pattern of random right-censorship. The test is a generalization of the one proposed by Slivka (1970) which is useful when testing time is expensive so that an early termination of an experiment is desirable. The power of the test is examined in a simulation study.     

Bootstrap confidence interval estimates of cpk: an introduction

The interpretation of C_pk:, a common measure of process capability and confidence limits for it, is based on the assumption that the process is normally distributed. The non-parametric but computer intensive method called Bootstrap is introduced and three Bootstrap confidence interval estimates for C^ are defined. An initial simulation of two processes (one normal and the other highly skewed) is presented and discussed     

Children's response to the medical visit for allegations of sexual abuse: maternal perceptions and predicting variables

This study examined maternal perceptions of their child's response to the medical evaluation for alleged sexual abuse. A total of 50 mothers were interviewed 6 months after a visit to a Child Protection Clinic for a medical evaluation of alleged sexual abuse. The mothers answered a questionnaire on their child's reactions to the medical visit. More than 60% of children were perceived as being reassured about physical integrity. The degree of psychological distress was independent of perpetrator's identity and severity of the abuse. Mothers considered that a hypothetical second visit would generate in their child a level of anxiety that increased with perceived intensity of fear of the examination and decreased with perceived kindness of the physician. These results suggest that the physician's behaviour during the medical evaluation for alleged sexual abuse has an influence on the child's degree of distress that is independent of type and severity of abuse.

Learning and Organization in the Knowledge‐Based Information Economy: Initial Findings from a Participatory Action Research Case Study

This paper reports on an ongoing, multiphase, project‐based action learning and research project. In particular, it summarizes some aspects of the learning climate and outcomes for a case‐study company in the software industry. Using a participatory action research approach, the learning company framework developed by Pedler et al. (1997) is used to initiate critical reflection in the company at three levels: managing director, senior management team and technical and professional staff. As such, this is one of the first systematic attempts to apply this framework to the entire organization and to a company in the knowledge‐based learning economy. Two sets of issues are of general concern to the company: internal issues surrounding the company's reward and recognition policies and practices and the provision of accounting and control information in a business‐relevant way to all levels of staff; and external issues concerning the extent to which the company and its members actively learn from other companies and effectively capture, disseminate and use information accessed by staff in boundary‐spanning roles. The paper concludes with some illustrations of changes being introduced by the company as a result of the feedback on and discussion of these issues.     

Coping with racial battle fatigue: differences and similarities for African American and Mexican American college students

Student of Color often reference racial microaggressions when asked to describe their post-secondary experience. The racial battle fatigue framework assists in understanding the cumulative, negative effect of racial microaggressions on psychological, behavioral, and physiological outcomes. This paper assesses the racial battle fatigue framework for African American and Mexican American college students and the impact of coping on racial stress. Results demonstrate that racial microaggressions negatively impact stress responses for African American and Mexican Americans differently, but coping may help alleviate the impact of racial battle fatigue. Universities can address racial microaggressions and negative health outcomes by educating campus constituents about racial microaggressions, addressing Whiteness, and providing education about adaptive coping strategies.
