Designing np control charts

This paper presents the results of a simulation approach to the design of economic attribute control charts. The approach taken differs from the classical studies reported in the literature in two respects. First, the often made assumption that the out-of-control state of a process will remain so until detection is relaxed. This in effect allows the average proportion of defectives to deteriorate further before the out-of-control state is detected. Second, there is no requirement for detailed information on the exact process behaviour in the out-of-control state. It is assumed that a multitude of out-of-control causes exist and that the proportion defective is equally likely to be within a specified range of values. The relaxation of these two assumptions makes the model realistic and gives it wide practical applications in the control of a manufacturing process. The simulation computer programs developed are sufficiently compact to run on the low cost microcomputers.     

Empowerment through work: the cases of disabled individuals and low-skilled women workers on the US–Mexican border

This article discusses workers at two organizations: one employing disabled individuals and another employing low-skilled Mexican-American women. Workers at both organizations show positive effects from employment, including having increased self-efficacy and self-esteem, valuing work as a source of income and personal growth, as well as developing a sense of community. These perceptions contrast sharply with statements presented about how they viewed themselves and their abilities before working in these organizations. Through comparisons between these two sets of experiences, we show how individuals draw meaning, dignity, self-esteem, and empowerment from work.     

The inter-rater reliability and validity of self-report of risk factors for cumulative trauma disorders within the hand therapist population - a pilot study

OBJECTIVES: This study examined the validity of hand therapists' self-report of cumulative trauma disorder (CTD) risk factors by comparing the self-report to observations performed by the raters. Inter-rater reliability was also analyzed between the raters who observed the hand therapists. STUDY DESIGN: Two raters simultaneously observed each hand therapist during a splinting task at a therapy facility. Following this task, the raters and the hand therapist independently completed an identical assessment tool. Thirteen therapists were observed and a total of six raters observed the therapists. Responses from two categories of the self-assessment, "posture" and "mechanical stress", were compared. Percentage of agreement was calculated by dividing the number of like responses by the total number of possible responses for each category. RESULTS: Overall inter-rater reliability was 72%, significantly above the accepted minimum standard of 60-70%, and validity was 39%, significantly below the accepted minimum. CONCLUSION: The high percentage of inter-rater reliability established consistency and accuracy among the raters in their observations. However, the low percentage of validity should prompt hand therapists to investigate the accuracy of a patient's self-report before relying on it for treatment.     

Critical success factors and green supply chain management proactivity: shedding light on the human aspects of this relationship based on cases from the Brazilian industry

Abstract

By applying the resources-based view (RBV) theory to green management, this study aims to analyse the relationship between critical success factors (CSFs) and the adoption of green supply chain management (GSCM) practices for some Brazil-based manufacturers of automotive batteries considered focal in their supply chains. It also analyses how human issues, known as green human resource management (GHRM) aspects, can help to increase the effectiveness of CSFs for GSCM strategies that are still not totally well-managed, justifying a RBV perspective. This research assumes that firms tend to be in different stages of GSCM development (more strategic or less strategic) and tests four research propositions to determine whether more proactive GSCM is related to higher levels of effectively managed CSFs. Three focal companies that operate in the Brazilian automotive battery industry were studied. Research results suggest that more proactive GSCM practices correlate to more effectively managed CSFs and to a greater support from GHRM. We argue that managers with a clear GHRM strategy will have more success in GSCM adoption, using more green training, green recruitment and selection, green performance evaluation and employee rewards.     

What Is a Social Enterprise? Revising Old Concepts and Interviewing Social Entrepreneurs

The concept of social enterprise (SE) has been developed by an emerging and collective effort of scholars over the world. However, a comprehensive meaning of ‘SE,’ which embeds traditional knowledge of organizational management has potential to be explored further. Due to the relevance of ‘SE’ in the contemporary society, new conceptual and practical insights are desirable. This study proposes to shed light on building up a definition for ‘SE’ that is inspired by existing definitions of organization and ‘SE’ and rely on real-world evidence. Literature review and comprehensive interviews with social entrepreneurs were conducted. Data analysis defines ‘SEs’ as an autonomous organization managed in a participative way and created by and for the community, with a relatively identifiable boundary, that strives to generate social wealth, and for this, produces goods and/or services that guarantee its financial viability, consequently, its continuity. Its integration into its environment generates consequences guided by social, economic, and environmental goals.     

The dynamic,complex and diverse living and care arrangements of young New Zealanders: implications for policy

The living arrangements of young people in New Zealand are diverse and often complex. In this article we report the range of care and living arrangements of 209 15-year-old New Zealanders, 47 of whom identified as Māori. These young people were participants in the second generation of a cohort study. Data were collected from their parents via a life history calendar and analysed for variety and consistency of care arrangements, household membership and transitions. Few participants had a consistent pattern of parental care arrangements and most had experienced multiple changes in household composition and frequent changes of address. We conclude that the whānau/family lives of many young New Zealanders are complex and dynamic. These observations contrast with the conventional notions of family life that form the basis for New Zealand’s family policies. We argue that social policies and services impacting on young people need to reflect the lived reality of young people if they are to meet young people’s needs.
