Age and Gender Differences in Perceived Accident Likelihood and Driver Competences

Road traffic accident involvement rates show clear age and gender differences which may in part be accounted for by differences in risk perception and perceptions of driving competence. The present study extends and replicates that of Matthews and Moran (1986). Young (18–30 years) and older (45–60 years) male and female drivers responded to a questionnaire on perceived accident risk and driving competence (judgment and skill) with respect to themselves and four target groups, and also rated a series of videotaped driving sequences with respect to likelihood of accident occurrence and perceived driving competence. Results showed that effects of rater characteristics were generally confined to the questionnaire. Younger males were perceived as most likely to experience an accident and were judged to be lower than other groups in driving competence. Younger groups showed little bias against older groups and vice versa , but gender-related bias was apparent. The findings of Matthews and Moran were generally confirmed. The results are discussed with reference to four main issues: (1) demographic bias effects—which are generally weak; (2) stereotyping on the basis of gender and/or age of driver; (3) group-specific bias; (4) self-appraisal bias.     

A stakeholder perspective on process improvement behaviours: delivering the triple bottom line in SMEs

Abstract

The primary focus of operations management is to add value through operational processes. Considerable attention has been given to using process improvement (PI) techniques to reduce costs and time, in order to develop a competitive advantage for the wider organization. However, this narrow definition of value at times overlooks the triple bottom line (TBL) which can result in a number of unintended consequences, specifically issues related to environmental and social measures of performance. To address this, a stakeholder theory lens will be used to analyze PI activities within the context of small and medium-sized enterprises. The TBL will be used to complement the stakeholder perspective, to interpret the benefits that are realized from PI activities. This article highlights both the direct benefits from PI as well as more indirect benefits realized by involving a selection of salient stakeholders in PI. It will show how a developed view of PI can provide an important mechanism for delivering improvements to a firm’s TBL. The work concludes by highlighting the contributions made to both PI practice and stakeholder theory, while acknowledging the need for more research on PI, both from a stakeholder perspective and how it impacts a firm’s TBL.     

Gender differences in life expectancy free of impairment at older ages

This article uses data from the United Kingdom Medical Research Council Cognitive Function and Ageing study (MRC CFAS) to analyze morbidity associated with three areas of impairment. We use cognitive status, functional status, and physical illness to examine differences in the proportion of time that older women and men will spend with co-morbidity. We also analyze differences among various impairments, and investigate the relationship between missing data and sex. Women have a larger burden of impairment than men, and, by including cognitive impairment together with functional impairment, a very large impairment burden is highlighted at all ages. Policy implications of the findings from the perspective of older women in the United Kingdom are discussed.     

Viewing psychopathology through a trauma lens

Many symptoms and behaviors associated with a range of psychiatric disorders, including those not designated as trauma- or stressor-related, result from unprocessed and unintegrated traumatic experiences, requiring therapeutic assessments and interventions that consider the complex dynamics brought on by trauma. While the focus on symptoms in the Diagnostic and Statistical Manual of Mental Disorders (DSM) may lead practitioners away from a consideration of etiology when choosing interventions, the exclusions of “disorders of extreme stress not otherwise specified” in DSM-IV and “developmental trauma disorder” from DSM-5 may further predispose practitioners to disregard traumatic etiology and symptoms when assessing, diagnosing, and treating clients. Because a majority of recipients of public mental health services suffer deleterious effects from trauma exposure, social work and other mental health professionals have an ethical responsibility to incorporate trauma-based screenings, assessments, and interventions with clients. Thus, trauma-informed evaluation and treatment approaches must be included in graduate curricula, practitioners must seek continuing education to supplement their knowledge and practice skills, and agency administrators must provide inservice training to professional staff.     

PROCEDURES FOR DETERMINING RELATIVE FREQUENCIES OF PRODUCTION/ORDER IN MULTISTAGE ASSEMBLY SYSTEMS*

We show that the problems of determination lot sizes in a multistage assembly system for the case of instantaneous production and constant demand for the end item can be reduced to the problems of determining relative frequenceis of production/order for items at each production stage. We further show that such frequencies are independent of the demand levels. Optimal and near-optimal solution procedures for this reduced problem are provided. The near-optimal procedure successively treats each stage of production as a final production stage while simulatenously incorporating decisions made at lower stages into decisions made at higher stages. Experimental results show that the near-optimal procedure results in optimal solutions 75 percent of the time and performs considerably better than representative heuristics available in the literature. Further, its performance is relatively less susceptible to product/structural characteristics of the system.     

Learning to listen: epistemic injustice and gothic film in dementia care education

Listening is a critical and under-theorized dimension to struggles against injustice and marginalization. In the wake of critiques from the disability movement of the pre-eminence of expert medical voices, educating professionals to listen to health service users has become particularly critical. The utterances of people with dementia have frequently been subject to, in Miranda Fricker’s terms, “testimonial injustice”: that is, seen as irrational, unreliable, and not to be believed. This article will examine the way in which the generic conventions of the gothic, more specifically what Mary Ann Doane has described as “the paranoid women’s film,” are used in a short film, Darkness in the Afternoon, widely screened in dementia care education in the UK and internationally. Drawing on interviews with dementia care trainers, analysis of training materials, and the film itself, this article proposes that gender and genre is used in this film as a strategy to reorient the listening and affective practices and testimonial sensibilities of health and aged care workers.     

Urban Poverty and Neighborhood Effects on Crime: Incorporating Spatial and Network Perspectives

Research on neighborhoods and crime is on a remarkable growth trajectory. In this article, we survey important recent developments in the scholarship on neighborhood effects and the spatial stratification of poverty and urban crime. We advance the case that, in understanding the impact of neighborhoods and poverty on crime, sociological and criminological research would benefit from expanding the analytical focus from residential neighborhoods to the network of neighborhoods that individuals are exposed to during their daily routine activities. This perspective is supported by re‐emerging scholarship on activity spaces and macro‐level research on inter‐neighborhood connections. We highlight work indicating that non‐residential contexts add variation in criminogenic exposure, which in turn influence offending behavior and victimization risk. Also, we draw on recent insights from research on gang violence, social and institutional connections, and spatial mismatch and call for advancements in the scholarship on urban poverty that investigates the salience of inter‐neighborhood connections in evaluating the spatial stratification of criminogenic risk for individuals and communities.
