An economic model for the quality selection problem

The object of an economic model for the quality selection problem is to select the best parameter value for an input quality characteristic (X) so that the quality loss incurred on an output quality characteristic (Y) is minimized. The relation function between Y and X is assumed to be known throughout the article. In the work of Taguchi's experimentations, the selection of best parameter values is solved by two-step optimization when Y is adjustable. In the article, it is further extended to the case where Y is non-adjustable. An economic quality selection model with a general relation function is proposed based on a Taylor-series method for both adjustable and non-adjustable cases. A special case of a quality selection model with a quadratic relation function is also studied. A circuit example provided by Taguchi is presented to illustrate the use of this model.     

Staying well or burning out at work: Work characteristics and personal resources as long-term predictors

The aim of this longitudinal study was to recogmize the work characteristics and personal resourcesthat are associated with burnout symptoms in the long term. The empirical analyses are based onsample data (n = 174) from a larger survey in 1986 and from a 10-year follow up in 1776 conducted inan international industrial foresty enterprise. The participants were drawn from those worken inFinland, the home country of the enterprise, who responded to the questionnaires at both times. Theparticipants were classified into those having no burnout and those with serious burnout. In order tocompare the groups a multivariate analysis of variance and t-tests for two independent groups wereused. Four job-related and five organizational factors, 10 work environment hazards and threeindividual variables wereused as a predictors. Change variables were formed from the predictors. Allthe significant changes in work and personal resources during 10 years had shifted to the positivedirection in the no-bumout group, and to the negative direction in the serious burnout group.Discriminant analysis was used to identify linear combinations of quantitative predictor variables thatbest characterized the differences between the groups. Both the cross-sectional and the longitudinalpredictors showed that factors related to the social processes at work seem to be crucial to burnout. Ofthe individual resources, a strong sense of coherence seems to be of particular importance.     

Effects of resident-oriented care on job characteristics of nursing caregivers

This study evaluates the effects of the implementation of resident-oriented care on the job characteristics (job autonomy, job demands and social support) of nursing caregivers in three Dutch nursing homes. In a quasi-experimental design, experimental and control groups in both general and psychogeriatric wards were followed for up to 22 months, using a pre-test and two post-tests by means of written questionnaires and semi-structured interviews. The results showed that the intervention appeared to be partly successful. Last post-test regression analyses revealed significant increases in a number of design characteristics of resident-oriented care. Significant increases were noticed on resident assignment, the two variables measuring the nursing process and, in the psychogeriatric experimental group, on resident-oriented tasks (p≤.01). The effects on job characteristics were limited. An indicative increase was shown in contextual job autonomy in the experimental group (p≤.05). The qualitative data derived from the interviews showed that there was still a partly task-oriented division of labour. Further, the delegation of co-ordination tasks to nursing caregivers had not yet been properly achieved. The study concludes with some theoretical and methodological reflections in the light of the findings.     

Associations between stress at work and attitudes towards retirement in hospital physicians

Abstract

There is a need to understand the associations between attitudes towards retirement in specific occupations and various psychosocial and work-related factors. This study identified correlates of retirement thoughts and retirement preference in hospital physicians. The sample comprised 447 (251 male and 196 female) physicians from three hospital districts in Finland. After adjustment for gender, age and salary, minor psychiatric morbidity increased likelihood of retirement thoughts and retirement preference. Retirement thoughts and retirement preference were more common in doctors reporting low job control, poor teamwork and unjust supervision than in doctors perceiving their working conditions more favorably. Work preference was associated with high overwork. The associations of work characteristics with retirement thoughts and retirement preference largely persisted after control for indicators of health and social circumstances. In conclusion, in addition to demographic and financial factors and health, retirement attitudes in hospital physicians seem to be related to organizational and managerial factors that are potentially amendable to intervention. This has implications for retaining hospital physicians who might otherwise retire.     

Decision latitude,job demands,and employee well-being

Abstract

Karasek (1979) drew attention to the possibilities that job characteristics may be non-linearly associated with employee well-being, and that they may combine interactively in relation to well-being. This paper examines those issues, and finds that both linear and non-linear components are present in relationships between job features and well-being. However, there is no evidence for a synergistic interaction between decision latitude and job demands. Those job features are differentially predictive of two aspects of well-being: job-related depression-enthusiasm and anxiety-contentment.     

金融发展、技术创新与经济增长的关系研究——基于中国的省市面板数据

本文基于中国31个省市2000-2011年的面板数据,依次运用面板数据的单位根检验、协整检验和因果有向无环图(DAG)等分析方法,旨在探讨金融发展、技术创新与经济增长之间的影响关系。研究结果表明:金融发展、技术创新与经济增长两两之间存在长期均衡的协整关系;金融发展是引致技术创新的直接原因,即国内金融发展和R&D投入之间具有很强正向关系,但以银行主导的金融发展结构不利于R&D投资;技术创新是显著促进经济增长的直接原因;金融发展是引致经济增长的直接原因,也是间接原因,一方面,在发展水平较低的国家内,银行主导的金融结构对经济增长具有显著的正向作用,而金融发展规模对经济增长具有显著且直接的负向作用,但它可以通过促进R&D投入来间接地促进经济增长。     

Work–family conflict: The importance of differentiating between different facets of job characteristics

This review study clarifies the relationships between job characteristics and work–family conflict (WFC) by differentiating among three facets of job characteristics: latent, perceived, and enacted. To date, research linking job characteristics to WFC has not distinguished the facets of job demands and job resources in this way. Such distinctions are important as a means of understanding the affective, behavioural, and cognitive processes involved in determining how and when job characteristics relate to WFC. Our review of 115 studies showed that perceived job characteristics have been most commonly explored in relation to WFC, whereas latent and enacted job characteristics have been hardly examined. While these findings may not be surprising, our contribution lies in reviewing the literature through the lens of these categories. Based on the findings, and through highlighting examples in the extant literature, we argue that understanding job characteristics in terms of both how they are perceived and enacted by workers will provide a deeper insight into the mechanisms underlying the relationship between job characteristics and WFC. In order to inform evidence-based interventions, future research must uncover the dynamic mechanisms underpinning the connection between job characteristics and WFC through a focus on enacted job facets and the cognitive, affective, and behavioural processes involved.     

Carry on Shrinking?: The Bankruptcy of Urban Policy in Detroit

Much attention has recently been focused on the bankruptcy of the City of Detroit in 2013 and the reasons for the largest municipal fiscal melt down in US history. Contrary to a view gaining currency, which dismisses Detroit as the product of exceptional forces and largely calls it the architect of its own collapse, this article argues the case that Detroit conveys more general lessons for European cities struggling with decline, not least of which is the need for interventionist regional planning to avoid predictable but avoidable urban distress. The article briefly reviews the well-documented decline of the city of Detroit measured against population, economic, fiscal and image impacts. It considers five current misreadings of the reasons for Detroit's predicament and implicit signposts for European practice before concluding with an assessment of what has been hailed as the shoots of yet another possible renaissance in the originally proclaimed Renaissance City over 40 years ago.     

Unequal Regionalism: Regional Planning in China and England

This paper responds to the revival of regionalism in the past two decades by showing that such a re-emergence is unequal. Comparing the practice of regional planning in China and England, this paper has demonstrated that the party-state in China and the liberal-democratic state in England have responded differently to this revival and developed different framework for regional administration and planning. These variations have not only elaborated planners' concern about planning practice in a ‘context of difference’ from social dimension to geographical variations, but also echoed geographers' affirmation that global trends take on different characters in local setting.     

中国入世以来经济增长、外贸及FDI对就业的影响

文章建立了关于就业的线性计量模型,并通过中国30个省2002-2006年的面板数据,主要检验了中国入世以来经济增长、外贸、FDI等对于就业的作用。经济增长仍显著促进了就业增加;FDI促进了就业增加,但拉动作用较小,东部与西部的FDI并未显著促进就业;总体上,出口拉动了就业增加,但其作用也不是很大,仅东部的出口显著促进了就业增长;进口显著抑制了国内就业。并在上述分析基础上,提出了相应的政策见解。
