Location, Location, Location: Does Place of Work Really Matter?

This paper examines the work attitudes of home- and office-based workers. A review of the existing literature finds both pessimistic and optimistic accounts of the impact of homeworking on employee attitudes and behaviours. Drawing on a survey of 749 managerial and professional employees in knowledge-intensive industries, the study finds more support for the optimistic perspective. The findings suggest that homeworking is positively associated with employee well-being and a more balanced work–home relationship. There is no evidence that organizational citizenship behaviours are reduced by homeworking but there is some support for homeworking undermining employees' perception of the organization as supporting their careers and personal development.     

‘Management Standards’ and work-related stress in the UK: policy background and science

In the late 1990s, the Health and Safety Commission, as the lead authority in the UK responsible for Health and Safety at Work, conducted an extensive consultation exercise to elicit views about how work-related stress should be tackled. The Commission subsequently decided that regulation was not justified and opted for an approach with four strands. One of these was to work with stakeholders to develop clear, agreed standards of good management practice. This paper describes and discusses the rationale behind a standards-based approach that is essentially based on a method of controlling hazards. The Management Standards approach uses a taxonomy of six stressors that has evolved out of extensive research carried out on behalf of the UK's Health and Safety Executive (HSE) and in conjunction with stakeholders, and a three-phase risk assessment methodology. Further developmental work on the standards (which are to be subjected to public consultation) and associated measurement tools is described in a companion paper in this issue of Work & Stress (Cousins, Mackay, Clarke, Kelly, Kelly, & McCaig, ). The emphasis is on prevention towards reducing stress in the UK working population. We review current thinking on models of work stress, consider evidence linking workplace psychosocial factors and various health and organizational outcomes, and examine the effectiveness of organizational interventions. We argue that the literature supports an approach that aims to move organizational states (represented by the current situation) to more desirable ones (represented by the six Management Standards), and that this is an effective ‘population’ based approach to tackling workplace stress and promoting individual and organizational health.     

Large sample properties and confidence bands for component-wise varying-coefficient regression with longitudinal dependent variable

Longitudinal studies with repeatedly measured dependent variable (out-come) and time-invariant covariates are common in biomedical and epidemi-ological studies. A useful statistical tool to evaluate the effects of covariates on the outcome variable over time is the varying-coefficient regression, which considers a linear relationship between the covariates and the outcome at a specific time point but assumes the linear coefficients to be smooth curves over time. In order to provide adequate smoothing for each coefficient curve, Wu and Chiang ( 1999 ) proposed a class of component-wise kernel estimators and determined the large sample convergence rates and some of the constant terms of the mean squared errors of their estimators. In this paper we calcu¬late the explicit large sample mean squared errors, including the convergence rates and ail the constant terms, and the asymptotic distributions of the kernel estimators of Wu and Chiang ( 1999 ). These asymptotic distributions are used to construct point-wise confidence intervals and Bonferroni-type confidence bands for the coefficient curves. Through a Monte Carlo simulation, wre show that our confidence regions have adequate coverage probabilities. Applying our procedures to a NIH fetal growth study, we show that our procedures are useful to determine the effects of maternal height, cigarette smoking and al¬cohol consumption on the growth of fetal abdominal circumference over time during pregnancy.     

Society and Social Security in France

An overview is given of some salient demographic characteristics in the dramatically changing socio-economic environment of France. Examination of social security and medical insurance provision shows how social welfare benefits have become more or less vital in the French family's maintenance of improved living standards. It is concluded that French social security services now compare favourably with provisions in other countries, but that birth-rate problems and other social effects of rapid developmental change remain to be overcome.     

INDIVIDUALS WITH INTELLECTUAL DISABILITY AND MENTAL ILLNESS: A LITERATURE REVIEW

This review highlights the urgency for a seamless and co‐ordinated approach to service delivery for people with intellectual disability and mental illness. There is emerging evidence of the high prevalence of mental illness in persons with intellectual disability. The notion that people with intellectual disability can have mental illness has only been recently acknowledged. Furthermore, people with intellectual disability also experience a wide range of psychiatric disorders often seen in the general population. Despite of recent developments in treatment options for these people, many of them continue to experience barriers in accessing mental health services.     

Neighbourhood Life,Social Capital and Perceptions of Safety in the Western Suburbs of Adelaide

In this paper we report on a South Australian study of perceptions of safety and aspects of neighbourhood life including social capital which involved the analysis of 2400 self‐completed questionnaires. A path analysis found that perceptions of safety were directly associated with gender, age, perceptions of neighbourhood pollution and neighbourhood trust, and indirectly associated with age, neighbourhood pollution and neighbourhood connections. We conclude with a discussion of the implications of the findings for public policy.
