A Bayesian nonparametric model for Taguchi's on-line quality monitoring procedure for attributes

A Bayesian nonparametric model for Taguchi's on-line quality monitoring procedure for attributes is introduced. The proposed model may accommodate the original single shift setting to the more realistic situation of gradual quality deterioration and allows the incorporation of an expert's opinion on the production process. Based on the number of inspections to be carried out until a defective item is found, the Bayesian operation for the distribution function that represents the increasing sequence of defective fractions during a cycle considering a mixture of Dirichlet processes as prior distribution is performed. Bayes estimates for relevant quantities are also obtained.     

Cultural and societal influences on shared leadership in globally dispersed teams

Leading globally dispersed teams poses critical challenges, especially if the team members are not only physically separated, but also culturally diverse and their tasks are dynamic and complex. It has been argued that shared leadership behaviors, such as continuous reflection, anticipation of a team's information needs, and initiating a team's social influence, positively influence virtual team performance. Country-level effects on shared leadership in globally dispersed teams, however, have been neglected. Building on the country institutional profile developed by Kostova (1997), we argue that regulative, cognitive, and normative components influence the likelihood that the individual will engage in shared leadership behaviors. Analyzing the differences between the institutional profiles of team members' home countries as reflected in institutional diversity as a team-level property, we furthermore point to different levels of institutional diversity as an enabling or hindering condition of shared leadership.     

An International Perspective of Field Instruction

Abstract

Social work educators and practitioners have long debated several issues confronting field instruction. For example, they have addressed the structure of field placement, school versus agency-based supervision, remuneration to agencies that accept student placements, and the use of employer agencies as field settings. Because problem-solving increasingly involves working with people in nations other than the United States, it is important to gain an international perspective on field instruction issues. To this end, an international study was conducted to examine social work field instruction and the educational context in which it occurs. This article reports the findings of that study, which involved 51 countries. The universality of field instruction as an integral part of educational program, is apparent, as are the similarity of issues, problems, and proposed solutions Moreover, the findings indicate areas in which social work education has greater international consistency than education for the professions within national and regional boundaries, whereas other areas are influenced more by national and regional factors than by a universal social work professional culture.     

Cultural adaptations in psychosocial interventions for post-traumatic stress disorder among refugees: A systematic review

ABSTRACT

The aim of this study was to systematically review randomized controlled trials on non-pharmaceutical interventions for post-traumatic stress disorder (PTSD) among adult refugees with a focus on identifying common cultural adaptations and reviewing possible effects of such adaptations on outcomes. The conducted systematic search yielded 11 studies. The strongest support was for eye movement desensitization and reprocessing (EMDR). Commonly used cultural adaptations in the reviewed studies included modifications in personnel and setting context, changes in content, and translation or adaptation of evaluation tools.     

Inclusion of caregiver supports and services in home- and community-based service programs: recent reports from state units on aging

Caregivers have an important role in assisting frail and/or disabled individuals to maintain their independence in the community. Support to assist caregivers in this often stressful and demanding role is critical to sustaining the caregivers' health and ability to provide care. This paper reviews federal policy changes since 2000 that have expanded and enhanced services for informal caregivers. Next, data collected from State Units on Aging and other state agencies are presented to describe the extent to which caregiver services are included in home- and community-based programs under three funding streams (Medicaid waivers, Centers for Medicare and Medicaid Services-funded programs, and state-funded programs). Program characteristics, such as eligibility and consumer-directed options, are included. Finally, the accomplishments and initiatives reported by state respondents related to supporting informal caregivers are also explained. Results indicate that services for informal caregivers are receiving greater attention and are frequently offered under home- and community-based service programs by the states that participated in this study.     

Modeling Lung Carcinogenesis in Radon‐Exposed Miner Cohorts: Accounting for Missing Information on Smoking

Epidemiological miner cohort data used to estimate lung cancer risks related to occupational radon exposure often lack cohort‐wide information on exposure to tobacco smoke, a potential confounder and important effect modifier. We have developed a method to project data on smoking habits from a case‐control study onto an entire cohort by means of a Monte Carlo resampling technique. As a proof of principle, this method is tested on a subcohort of 35,084 former uranium miners employed at the WISMUT company (Germany), with 461 lung cancer deaths in the follow‐up period 1955–1998. After applying the proposed imputation technique, a biologically‐based carcinogenesis model is employed to analyze the cohort's lung cancer mortality data. A sensitivity analysis based on a set of 200 independent projections with subsequent model analyses yields narrow distributions of the free model parameters, indicating that parameter values are relatively stable and independent of individual projections. This technique thus offers a possibility to account for unknown smoking habits, enabling us to unravel risks related to radon, to smoking, and to the combination of both.     

Perpetual Silence,Not Silence for Moments: Hearing Loss of Children as Perceived by Hearing Bedouin Mothers

The Negev Bedouin population in southern Israel, a minority undergoing great social change, has a higher incidence of hearing loss than that reported elsewhere but has hardly been studied. Caring for a child with hearing loss often engenders parental stress because of the many tasks involved. Difficulty in accessing information and services, the lack of public transportation nearby, and other aspects of the living conditions of Negev Bedouin parents present additional challenges. These difficulties are further compounded by the unique socio-demographic and cultural characteristics of this indigenous population. This article presents the parenting experience of 20 hearing Bedouin mothers of children with hearing loss, explored in a qualitative phenomenological study. The findings indicate that the mothers’ perceptions of the child’s hearing loss affect how they cope with the birth and rearing of the child, their view of the child, and their attitude toward medical interventions. These findings, which portray an experience that is unique in many ways, contribute to the understanding of how an underserved, indigenous, and traditional population responds to congenital hearing loss. The findings also reveal the importance of the terminology with which parents describe their child’s hearing loss and the unique meanings it may have. Such knowledge is of particular importance for culturally sensitive and effective provision of social services and therapeutic interventions.     

Food for Thought: Analyzing Public Opinion on the Supplemental Nutrition Assistance Program

ABSTRACT

This project explores public opinion on the Supplemental Nutrition Assistance Program (SNAP) in news and social media outlets, and tracks elected representatives’ voting records on issues relating to SNAP and food insecurity. We used machine learning, sentiment analysis, and text mining to analyze national and state level coverage of SNAP in order to gauge perceptions of the program over time across these outlets. Results indicate that the majority of news coverage has negative sentiment, more partisan news outlets have more extreme sentiment, and that clustering of negative reporting on SNAP occurs in the Midwest. Our final results and tools will be displayed in an online application that the ACFB Advocacy team can use to inform their communication to relevant stakeholders.     

Merkmale und Fragen einer Governance-Reform am Beispiel des österreichischen Schulwesens

Since the 1990s German speaking countries go through an increasing debate on modernising education systems. Based on an analysis of developments in Austria, but as a hypothesis for other German speaking school systems, the paper aims to identify some cornerstones of this discourse. It argues that a central element is the question how further developments of an education system may be productively steered and that the transformations in the idea of system steering may be conceptualized by an analytic concept of ‘governance’.
