Adjustment for nonresponse with variables from different sources: Bias correction and precision loss,with application to the Swiss European Social Survey 2012

ABSTRACT

Adjustment for nonresponse should reduce the nonresponse bias without decreasing the precision of the estimates. Adjustment for nonresponses are commonly based on socio-demographic variables, although these variables may be poorly correlated with response propensities and with variables of interest. Such variables nevertheless have the advantage of being available for all sample units, whether or not they are participating in the survey. Alternatively, adjustment for nonresponse can be obtained from a follow-up survey aimed at sample units which did not participate in the survey and from which the variables are designed to be correlated with response propensities. However, information collected through these follow-up surveys is not available for people in the sample who participated neither in the survey nor in its nonresponse follow-up. These two sets of variables when used in a nonresponse model for the Swiss European Social Survey 2012 differ only slightly with regard to their effect on bias correction and on the precision of estimates. The variables from the follow-up are performing slightly better. In both cases, the adjustment for nonresponse performs poorly.     

Heteroglossia in text‐messaging: Performing identity and negotiating relationships in a digital space

This article uses Bakhtin's concept of heteroglossia to explore how linguistic repertoires are exploited in the performance of identity and management of relationships through text‐messaging. The study focuses on text‐messages sent and received by ‘Laura’, a middle‐class woman who has returned from university to her family home in rural England. Qualitative analysis of Laura's texted exchanges, informed by quantitative corpus data and ethnographic interview, details the role of heteroglossia as Laura and her interlocutors position themselves in relation to each other and negotiate differences in gender, class, education, past experience, and personal aspiration. The study shows how heteroglossia can emerge even in interactions between individuals from similar backgrounds with largely shared language resources, and highlights the need for sociolinguistic studies of linguistic repertoire to consider the part that digitally‐mediated linguistic resources play in individuals’ wider identity projects.     

Invisible computer for collaborative design: evaluation of a multimodal sketch-based environment

In the areas of design, especially in architectural design, collaboration has become an important challenge. The specialization of skills increase, work teams are more and more extensive and the geographic distance between them increases too. The economic and ecological stakes related to remote collaboration are an evidence. This context involves the need to support most efficiently possible remote working meetings. We present the Distributed Collaborative Digital Studio (DSDC), a tool designed to recreate, in distant situations, the context of copresence meetings. This shared environment is created in the "invisible computer" approach [11]. The idea is that the tool should disappear from user's consciousness. Indeed, creative design activities require some fluidity in their process. Therefore, any involuntary interruption created by the system can potentially brake creativity. In this perspective, we investigate specifically the "invisibility" of our environment. To do this, we propose a framework for the operationalization of the concept and a methodology to test the system invisibility. This methodology was applied through a case study consisting of a corpus of 12 hours of remote collaborative design sessions with the DSDC. We highlight the learning effects while using our system, conclude on its effectiveness and discuss our methodology.     

Successful Word Recognition by 10‐Month‐Olds Given Continuous Speech Both at Initial Exposure and Test

Most words that infants hear occur within fluent speech. To compile a vocabulary, infants therefore need to segment words from speech contexts. This study is the first to investigate whether infants (here: 10‐month‐olds) can recognize words when both initial exposure and test presentation are in continuous speech. Electrophysiological evidence attests that this indeed occurs: An increased extended negativity (word recognition effect) appears for familiarized target words relative to control words. This response proved constant at the individual level: Only infants who showed this negativity at test had shown such a response, within six repetitions after first occurrence, during familiarization.     

Diverse Muslims in a Racialized Landscape: Race,Ethnicity and Islamophobia in the American City of Milwaukee,Wisconsin

Studying the racially and ethnically diverse Muslim minority population in any US city must take into account the racialized landscape prevailing in the city. Milwaukee is a highly racially segregated city, where residential patterns have been shaped by decades of immigration by various ethnic and racial groups, and by restrictions on residential housing, as well as industrialization, deindustrialization and suburbanization. This paper presents findings of an ethnographic research along with the results of a household survey of Muslims in Milwaukee in the context of Milwaukee's urban landscape. Muslims in Milwaukee are racially, ethnically and linguistically diverse. Their patterns of residence and of worship suggest the influence of not only segregation and the typical patterns of ethnic immigration but also clustering and dispersal. Patterns of residences also show the influence of not only Muslim leadership and organization but also of the racialized landscape of the city. Our survey provides a portrait of a community negotiating racial and ethnic differences and solidarities.     

The Role of Behavioral Theory in Model Development Research with Single Parent Families

In this paper, the authors critically examine the plight of single parent families with young children. Next, they lay out in detail the contributions of the behavioral perspective to practice model development research with single-parent families of children under the age of 12. The authors discuss implications for future theory driven practice model development research with cultural specific single parent families. They believe that future model development research efforts with culturally diverse single parent families will aid in advancing the state of cultural competence research in social work while assisting single parents relieve suffering and enhance child and family well-being.
