Zur Bedeutung von Faultlines als Grenzen bei der Teamarbeit

This report focuses on the divisions within and between teams. Such research is often associated with the phenomenon of “diversity”. Empirical evidence regarding the effects of diversity on teamwork is inconsistent, partly due to methodological limitations. We propose to use the concept of “faultlines” as hypothetical lines that divide teams into homogenous subgroups. Measuring faultlines as an objective indicator of team composition represents an innovative method for integrating several diversity attributes (e.?g., age, gender, and ethnicity). We provide an overview of the current research on faultlines and show detrimental effects of faultlines on team performance. Additionally, we present the results of two studies from the automotive industry, focusing on the relation between faultlines and organizational outcomes such as employee health, team performance and team identification. Finally, we conclude that the analysis of objective faultlines offers relevant implications for research and practice. Future research should also consider the role of subjectively experienced faultlines.

Linguistic practice and identity work: Variation in Taiwan Mandarin at a Taipei County high school

This article examines variation in the use of two Taiwan Mandarin features, de‐retroflection of sibilant fricatives [?] → [s], and labial glide deletion [w?] → [?], in the speech of Taipei County high school students. The features become resources for the negotiation of identity positions within the highly structured school institution. I discuss the correlations between the use of Taiwan Mandarin and two social factors: membership in the small culture (Holliday 1999 ) of a particular bānjí or class, and individual aspirations. Holliday's concept of small cultures is proposed as a variant of the Community of Practice. I refer to Bucholtz and Hall's ( 2004 ) tactics of intersubjectivity framework as a possible tool for explaining variation at the school. I argue that the two Taiwan Mandarin features are invoked to perform different social goals, which is possible because they are imbued with related but significantly different sociocultural meanings (Brubaker 2012 ; Baran 2007 ).     

Characterizing Poliovirus Transmission and Evolution: Insights from Modeling Experiences with Wild and Vaccine‐Related Polioviruses

With national and global health policymakers facing numerous complex decisions related to achieving and maintaining polio eradication, we expanded our previously developed dynamic poliovirus transmission model using information from an expert literature review process and including additional immunity states and the evolution of oral poliovirus vaccine (OPV). The model explicitly considers serotype differences and distinguishes fecal‐oral and oropharyngeal transmission. We evaluated the model by simulating diverse historical experiences with polioviruses, including one country that eliminated wild poliovirus using both OPV and inactivated poliovirus vaccine (IPV) (USA), three importation outbreaks of wild poliovirus (Albania, the Netherlands, Tajikistan), one situation in which no circulating vaccine‐derived polioviruses (cVDPVs) emerge despite annual OPV use and cessation (Cuba), three cVDPV outbreaks (Haiti, Madura Island in Indonesia, northern Nigeria), one area of current endemic circulation of all three serotypes (northern Nigeria), and one area with recent endemic circulation and subsequent elimination of multiple serotypes (northern India). We find that when sufficient information about the conditions exists, the model can reproduce the general behavior of poliovirus transmission and outbreaks while maintaining consistency in the generic model inputs. The assumption of spatially homogeneous mixing remains a significant limitation that affects the performance of the differential equation‐based model when significant heterogeneities in immunity and mixing may exist. Further studies on OPV virus evolution and improved understanding of the mechanisms of mixing and transmission may help to better characterize poliovirus transmission in populations. Broad application of the model promises to offer insights in the context of global and national policy and economic models.     

Die Verbreitung moderner Managementkonzepte im Mittelstand

Within existing studies on the diffusion of modern management concepts, such as Lean Management, Business Process Reengineering or Shareholder Value Management, small and medium-sized enterprises are frequently examined as a homogeneous group of hesitant adopters. Differences among small and medium-sized companies with regard to concept adoption can thus hardly be explained by referring to existing research. In this paper, we argue that differences in adoption patterns of modern management concepts across small medium-sized companies can be explained on the basis of their resource endowment and embedment in different social environments. We thereby employ central arguments from organizational diffusion theory. Based on a multivariate analysis of online-survey data on the diffusion of 22 modern management concepts among 272 German SMEs, our results show that adoption decisions are mainly based on relationships to local organizational environments, whereas concept awareness can be best explained by media-exposure.     

Palestine as ‘a state of mind’: second-generation Polish and British Palestinians’ search for home and belonging

This article reflects on the ways in which children of Palestinian exiles born in Poland and the UK relate to their ancestral homeland and how they make sense of their Palestinian inheritance in the present. It argues that while the second generation of Palestinian diasporic subjects maintain links with their parents’ homeland these connections are not limited to the intergenerational transmission of cultural identity. The article explores how Palestine ‘becomes’ important for second-generation Palestinians. It argues that it is the re-occurring waves of violence inflicted on Palestinians that activate and shape their engagement with Palestine. Rather than a sense of attachment based exclusively on a personal connection with ancestral ‘roots’, the article argues that the second generation also develop a sense of long-distance post-nationalism that transforms their connection with Palestine into a more universal endeavour for justice and against the dispossession. These arguments are based on the findings of a two-year multi-sited ethnography which involved oral history interviews with 35 Palestinians of different generations, carried out in Poland and in the UK, including 15 interviews with second-generation Palestinians, as well as site-specific field visits in Israel and Palestine and follow-up ‘return’ interviews.

Environmental Surveillance System Characteristics and Impacts on Confidence About No Undetected Serotype 1 Wild Poliovirus Circulation

Surveillance for poliovirus during the polio endgame remains uncertain. Building on prior modeling of the potential for undetected poliovirus transmission for conditions like those in Pakistan and Afghanistan, we use a hypothetical model to explore several key characteristics of the poliovirus environmental surveillance (ES) system (e.g., number and quality of sites, catchment sizes, and sampling frequency) and characterize their impacts on the time required to reach high (i.e., 95%) confidence about no circulation (CNC95%) following the last detected case of serotype 1 wild poliovirus. The nature and quality of the existing and future acute flaccid paralysis (AFP) surveillance and ES system significantly impact the estimated CNC95% for places like Pakistan and Afghanistan. The analysis illustrates the tradeoffs between number of sites, sampling frequency, and catchments sizes, and suggests diminishing returns of increasing these three factors beyond a point that depends on site quality and the location of sites. Limitations in data quality and the hypothetical nature of the model reduce the ability to assess the extent to which actual ES systems offer benefits that exceed their costs. Thus, although poliovirus ES may help to reduce the time required to reach high confidence about the absence of undetected circulation, the effect strongly depends on the ability to establish effective ES sites in high‐risk areas. The costs and benefits of ES require further analysis.     

Social Movements Seen as Radical Political Actors: The Case of the Polish Tenants’ Movement

This article casts new light on the processes of collective claims and identity formation in social movements, with the help of the radical political framework of Laclau and Mouffe (Hegemony and socialist strategy: towards a radical democratic politics, Verso, London, 2001). Polish tenants, classified as “losers” of transition and marginalized in the mainstream discourse, nevertheless act collectively, mobilizing alliances with other democratic struggles and thus challenge the hegemony of neoliberal dogmas in the country. The very fact of mobilization of a socially and economically deprived group demanding the right to the city is provocative in the studied context. The empirical foundations of our study are 20 in-depth semi-structured interviews conducted with Polish tenants’ activists cross-referenced with media material produced by and about the movement, and previous studies on the topic. The contribution of this article is twofold: it combines social movement theory with radical political framework and fills the empirical gap in the body of literature on social movements in post-socialist Europe.     

Posttraumatic stress and growth in student service members and veterans: The role of personal growth initiative

ABSTRACT

Objective: This study explored the extent to which personal growth initiative (PGI) may predict posttraumatic stress and growth in student service members/veterans (SSM/V). Participants: Participants were 136 SSM/V (79% men) representing multiple branches of the armed forces. Forty-four percent of participants reported having combat experience. Methods: Data collection occurred from October 2013 to February 2014. Data were collected via a Web-based survey that included demographics and measures of personal growth initiative, posttraumatic stress, posttraumatic growth, and perceived social support. Results: Results indicated that PGI is not a unique predictor of posttraumatic stress but is a unique predictor of higher levels of posttraumatic growth. PGI appears to be at least as important as perceived social support in facilitating growth in SSM/V. Conclusions: This study provides further evidence for PGI's potential to facilitate growth after a traumatic event.
