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.     

Parent – Adolescent Relationships and Girls’ Unhealthy Eating: Testing Reciprocal Effects

This longitudinal study tested the direction of associations between parent –adolescent relationships and adolescent girls’ unhealthy eating. Girls (N= 184) were seen at Time 1 (M age = 14.30 years), and then again 2 years later (Time 2; M age = 16.04 years). At both assessment periods, they completed measures that assessed their eating attitudes and behaviors, relationships with their parents, height, weight, and age of menarche. Whereas unhealthy family relationships have been hypothesized as a precursor to unhealthy eating attitudes and behaviors, it is also possible that increases in these behaviors contribute to more negative relationships within the family. Structural equation modeling was employed to simultaneously investigate the longitudinal influence of parent – adolescent relationships on girls’ unhealthy eating, and girls’ unhealthy eating on parent – adolescent relationships. The model was tested with the following controls: body mass (kg/m²), pubertal timing and age. A longitudinal direct effect was found for unhealthy eating on parent– adolescent relationships; however, no direct effect was found for parent– adolescent relationships on unhealthy eating over time. For middle– and late–adolescent girls, it appears that unhealthy eating behaviors and attitudes are predictive of less positive parent – adolescent relationships over time.

Multiple social contexts in qualitative bereavement research

Little research focuses on the ways that bereaved family members react to and make meaning of their experience of the death of an elderly father and husband. In a qualitative, ethnographic study of 34 bereaved families we examined how family members respond to two inter-related social contexts: 1. social-cultural values and attitudes such as attitudes toward grieving for old persons, and 2. the inter-personal dyadic relationship between interviewer and interviewee. An underlying theme of uncertainty pervades the study participants' views of what is normal and expected in their own process of bereavement. Implications for future bereavement research are suggested.     

Variation,contact and social indexicality in the acquisition of (ing) by teenage migrants1

We discuss some apparent limits on the acquisition of variation suggested by our recent work exploring how teenage migrants to the U.K. acquire local norms of variation. We focus on the constraints on the (ing) variable that emerged from a multivariate analysis. We find evidence for a systematisation of the variable among immigrants, involving
some linguistically and cognitively predictable constraints, but also the emergence of social constraints not found in the teenage native speakers. We argue that transformation of variable constraints is a necessary artefact of the inherent complexity of sociolinguistic variables, particularly those with social indexicality. This research note: (1) delineates some theoretical and practical questions involved in incorporating social indexing in variationist studies, especially of non‐native speakers; and (2) further explores reallocation (transformation) in the study of language contact. Wir behandeln mögliche Grenzen des Erwerbs soziolinguistischer Variation, die unsere jüngste Studie zum Erwerb lokaler Variationsnormen jugendlicher Immigranten in Großbritannien zu zeigen scheint. In unserer Ergebnisdarstellung konzentrieren wir uns auf die Faktoren, die die Verwendung der (ing) Variable beschränken. Die Ergebnisse gingen aus einer multivariaten Datenanalyse hervor. Wir zeigen, dass die Variable unter Immigranten systematisiert wird, was das Erscheinen einiger linguistischer und kognitiv voraussagbarer Faktoren aber auch einiger interessanter sozialer Faktoren einschließt, die nicht unter den jugendlichen Muttersprachlern gefunden werden konnten. Wir zeigen weiterhin, dass die Umwandlung variabler Faktoren ein notwendiges Artefakt der inhärenten Komplexität soziolinguistischer Variablen ist, insbesondere von Variablen mit sozialer Indexikalität. Diese Notiz umreißt einige praktische Fragen in Bezug auf (1) die Einfügung sozialer Indizes in variationslinguistische Studien, insbesondere solcher, die Nicht‐Muttersprachler betreffen, und (2) die weitere Erforschung des Prozesses der Umverteilung in der Untersuchung von Sprachkontaktphänomenen.

Concurrent Participation in Federally-Funded Welfare Programs and Empowerment Toward Economic Self-Sufficiency

This research examined the impact of participation in federal means-tested welfare programs on the attainment and maintenance of economic self-sufficiency. Using the Survey of Income and Program Participation (SIPP), this quasi-experimental investigation compartmentalized 4216 low-income households into an intervention group (n?=?2436) and a comparison group (n?=?1780). Households in the intervention group received one or more welfare benefits for the most part of the 2008–2013 quinquennium. By contrast, those in the comparison group – although eligible for these benefits – did not receive them. The survey respondents were measured repeatedly over a 56-month period to assess whether welfare receipt impacts their household income steadily beyond 150% of the federal poverty level, after controlling for known predictors. Multivariate analyses displayed medium effect sizes indicating that participation in public assistance did decrease the likelihood of economic self-sufficiency. Macro-implications of these findings for poverty and social welfare stakeholders were discussed.     

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.
