Migration background and educational tracking

Research on immigrants’ educational disadvantages documents substantial immigrant–native achievement gaps in standardized student assessments. Exploiting data from the German PIRLS extension, we find that second-generation immigrants also receive worse grades and teacher recommendations for secondary school tracks than natives, which cannot be explained by differences in student achievement tests and general intelligence. Second-generation immigrants’ less favorable socioeconomic background largely accounts for this additional disadvantage, suggesting that immigrants are disproportionately affected by prevailing social inequalities at the transition to secondary school. We additionally show that differences in track attendance account for a substantial part of the immigrant–native wage gap in Germany.     

Some differences in revealed behaviour under different inquiry methods

The paper is devoted to the assessment of the relevance of the they-come-to-play effect (CTPE, defined in the text). It employs both a real-effort setting and a questionnaire. The effect proves to be significant, albeit the results cannot be generalized straightforwardly. From the comparison between the real-effort setting and the questionnaire it turns out that subjects are influenced by their political preferences only in the latter.     

Identification and Estimation of Triangular Simultaneous Equations Models Without Additivity

This paper uses control variables to identify and estimate models with nonseparable, multidimensional disturbances. Triangular simultaneous equations models are considered, with instruments and disturbances that are independent and a reduced form that is strictly monotonic in a scalar disturbance. Here it is shown that the conditional cumulative distribution function of the endogenous variable given the instruments is a control variable. Also, for any control variable, identification results are given for quantile, average, and policy effects. Bounds are given when a common support assumption is not satisfied. Estimators of identified objects and bounds are provided, and a demand analysis empirical example is given.     

Three Forsaken Poets: Significant Absences in Balkan Modernism

ABSTRACT

Narratives dealing with the literary histories of South-Eastern Europe frame the canon of the nineteenth and twentieth century mostly in terms of rebirth, or re-awakening of a national culture. The literary history of Balkan modernisms and the avant-garde proves no exception to this rule. Its history has been often narrowed down to an often implicit monolingual canon with an ‘ethnic’ pedigree. This essay, although critical of these excluding mechanisms, does not propose a deconstruction of the national modernist canon. Instead, it wishes to reflect on alternative models for literary history, with alternative parameters that include figures of transition in terms of (national) language and ethnicity. It draws on three examples: Victor Tausk, Stanislav Vinaver and Monny de Boully.     

Developing people in a network of relational practices: reflections on the role of social work education

The mission of social work education in Flanders is threefold: to deliver education, to conduct research and to provide services to society. In our opinion social work education has a critical and liberating function towards society and it must stimulate and develop a critical attitude amongst students. In this article we first focus on the educational dimension of social work education as we practise this in one institute. Next we describe how we realise our objectives as a social work education institute in relation to the professional field. The central concept of our vision is social work as a relational practice.     

Quality of Web-based Information on Pathological Gambling

The present study aims to evaluate the quality of web-based information on gambling and to investigate potential content quality indicators. The following key words: gambling, pathological gambling, excessive gambling, gambling problem and gambling addiction were entered into two popular search engines: Google and Yahoo. Websites were assessed with a standardized proforma designed to rate sites on the basis of “accountability”, “presentation”, “interactivity”, “readability” and “content quality”. “Health on the Net” (HON) quality label, and DISCERN scale scores aiding people without content expertise to assess quality of written health publication were used to verify their efficiency as quality indicators. Of the 200 links identified, 75 websites were included. The results of the study indicate low scores on each of the measures. A composite global score appeared as a good content quality indicator. While gambling-related education websites for patients are common, their global quality is poor. There is a need for useful evidence-based information about gambling on the web. As the phenomenon has greatly increased, it could be relevant for Internet sites to improve their content by using global score as a quality indicator.     

Conditionally Reducible Natural Exponential Families and Enriched Conjugate Priors

Consider a standard conjugate family of prior distributions for a vector-parameter indexing an exponential family. Two distinct model parameterizations may well lead to standard conjugate families which are not consistent, i.e. one family cannot be derived from the other by the usual change-of-variable technique. This raises the problem of finding suitable parameterizations that may lead to enriched conjugate families which are more flexible than the traditional ones. The previous remark motivates the definition of a new property for an exponential family, named conditional reducibility. Features of conditionally-reducible natural exponential families are investigated thoroughly. In particular, we relate this new property to the notion of cut, and show that conditionally-reducible families admit a reparameterization in terms of a vector having likelihood-independent components. A general methodology to obtain enriched conjugate distributions for conditionally-reducible families is described in detail, generalizing previous works and more recent contributions in the area. The theory is illustrated with reference to natural exponential families having simple quadratic variance function.     

Instrumental Variables Estimates of the Effect of Subsidized Training on the Quantiles of Trainee Earnings

This paper reports estimates of the effects of JTPA training programs on the distribution of earnings. The estimation uses a new instrumental variable (IV) method that measures program impacts on quantiles. The quantile treatment effects (QTE) estimator reduces to quantile regression when selection for treatment is exogenously determined. QTE can be computed as the solution to a convex linear programming problem, although this requires first‐step estimation of a nuisance function. We develop distribution theory for the case where the first step is estimated nonparametrically. For women, the empirical results show that the JTPA program had the largest proportional impact at low quantiles. Perhaps surprisingly, however, JTPA training raised the quantiles of earnings for men only in the upper half of the trainee earnings distribution.
