Multiple belongings: transnational mobility,social class,and gendered identities among Polish migrants in Norway

ABSTRACT

Using ethnographic research in Norway and in Poland, this article focuses on the dynamics of multiple belongings of Polish migrants. It explores their experiences of belonging in relation to social class, gendered identities, and their different strategies of transnational mobility between Poland and Norway. By approaching belonging ‘from below’, we posit that it is a dynamic, processual, and socially and culturally constructed attachment to places, times, and communities, which includes experiential, practical, and affective dimensions. Considering the importance of questions of belonging and home-making in migrants’ lives, always contextually produced and read through performative reiterations, we focus on migrants’ daily routines and migratory practices, and argue that belonging is a multifaceted process, which takes on diverse forms and meanings of ‘who’ belongs to ‘what’, ‘where’ and ‘when’. Following intersectional perspective, the article aims at problematizing dependencies between mobility, gender, class, and migrants’ multiple belongings, and thereby, enhancing the understanding of the notion of belonging and its embeddedness in the inter-related social, cultural, economic, and political realms.     

State-dependent swap strategies and automatic reduction of number of temperatures in adaptive parallel tempering algorithm

In this paper we present extensions to the original adaptive Parallel Tempering algorithm. Two different approaches are presented. In the first one we introduce state-dependent strategies using current information to perform a swap step. It encompasses a wide family of potential moves including the standard one and Equi-Energy type move, without any loss in tractability. In the second one, we introduce online trimming of the number of temperatures. Numerical experiments demonstrate the effectiveness of the proposed method.     

Optimal global rates of convergence for nonparametric regression with unbounded data

Estimation of regression functions from independent and identically distributed data is considered. The _L2$L_2$ error with integration with respect to the design measure is used as an error criterion. Usually in the analysis of the rate of convergence of estimates a boundedness assumption on the explanatory variable X$X$ is made besides smoothness assumptions on the regression function and moment conditions on the response variable Y$Y$. In this article we consider the kernel estimate and show that by replacing the boundedness assumption on X$X$ by a proper moment condition the same (optimal) rate of convergence can be shown as for bounded data. This answers Question 1 in Stone [1982. Optimal global rates of convergence for nonparametric regression. Ann. Statist., 10, 1040–1053].     

Connectedness of complete block designs under an interference model

We consider an experiment with fixed number of blocks, in which a response to a treatment can be affected by treatments from neighboring units. For such experiment the interference model with neighbor effects is studied. Under this model we study connectedness of binary complete block designs. Assuming the circular interference model with left-neighbor effects we give the condition for minimal number of blocks necessary to obtain connected design. For a specified class of binary, complete block designs, we show that all designs are connected. Further we present the sufficient and necessary conditions of connectedness of designs with arbitrary, fixed number of blocks.

The social distance of Poles to other minorities: a study of four cities in Germany and Britain

This contribution investigates the social distance of immigrants from Poland in four Western European cities – London, Birmingham, Berlin and Munich – particularly Polish immigrants’ distance towards members of ethnic, religious and sexual minorities in their various social roles. Presenting unique data from the first wave of a longitudinal qualitative study, we first discuss the differential levels of social distance that Polish immigrants place between themselves and members of minority groups in each city. We find that respondents’ socio-demographic characteristics impact their social distance, but their education and occupation may have less of an effect than their place of origin in Poland or current place of residence and work. Moreover, these factors work differentially across the four cities. After analysing social distance with respect to three dimensions of difference – ethnicity, religion and sexuality – we find several different social-distancing mechanisms. Ultimately, we argue that social science needs to consider regional and local contexts in which social attitudes towards minorities are acquired and exercised. Similarly, we need to reflect on the group’s presumed homogeneity and on the unifying visions of the ‘host society’ as a site of migrants’ incorporation.     

Czesław Miłosz’s Self-presentation in English-Speaking Countries

Kosovo’s education system is divided along a Serb-Albanian line, with consequences for the non-Serb minorities. While Serb-Albanian relations have been researched and analyzed extensively, relations among non-Serb minority communities have typically been neglected. Although there are some studies addressing the treatment and rights of individual minority groups in Kosovo, there is very little written on the dynamics and relations those groups establish among themselves. This article uses education as the backdrop for analyzing the emerging inter-minority relations in Kosovo. The paper provides some background about minority education rights and the consequences of their partial implementation for those minority groups—i.e., the Kosovo Bosniaks and Turks—whose members opt to follow the Albanian (Kosovo) educational system. In addition, it offers insights into some of the economic and political considerations behind the decision of the Gorani community to endorse the Serbian educational system. Finally, I analyze the relations between the Goranis and Bosniaks that have been developing around education and language rights.     

Price Inference in Small Markets

This paper investigates the effects of market size on the ability of price to aggregate traders' private information. To account for heterogeneity in correlation of trader values, a Gaussian model of double auction is introduced that departs from the standard information structure based on a common (fundamental) shock. The paper shows that markets are informationally efficient only if correlations of values coincide across all bidder pairs. As a result, with heterogeneously interdependent values, price informativeness may not increase monotonically with market size. As a necessary and sufficient condition for the monotonicity, price informativeness increases with the number of traders if the implied reduction in (the absolute value of) an average correlation statistic of an information structure is sufficiently small.
