Immigrant students and their teachers – exploring various constellations of acculturation orientations and their impact on school adjustment

ABSTRACT

The present study examined what impact various constellations of acculturation orientations of immigrant students and their teachers have on the students’ school adjustment. For this purpose, the study analysed the acculturation orientations of 1106 5th graders and their class teachers in Switzerland. Using multiple regression analysis, we found that immigrant students were more satisfied at school if their teachers had similar attitudes about cultural assimilation and cultural diversity and could, thus, be said to have congruent acculturation orientations. With respect to students’ academic self-concept, immigrant students with a minority orientation whose teachers value cultural diversity including the heritage culture of their students showed a lower academic self-concept despite matching acculturation orientations. We interpret this result as a dilemma of teachers between the endeavour to develop culturally sensitive attitudes and behaviours and the risk to create stereotype threat and its negative effects through addressing cultural differences. Furthermore, a mismatch between the students’ (bi-)national identification at school and the teacher’s perception of the student as an immigrant or a native-born student could be shown to have adverse effects on the academic self-concept in the group of students with older teachers (50+ years).     

DOES PUBLIC ATTENTION REDUCE THE INFLUENCE OF MONEYED INTERESTS? POLICY POSITIONS ON SOPA/PIPA BEFORE AND AFTER THE INTERNET BLACKOUT

We investigate the role of public attention in determining the effect that campaign contributions by interest groups have on legislators' policy positions. We exploit the shock in public attention induced by the Internet service blackout of January 2012 that increased the salience of the Stop Online Piracy Act/Protect IP Act (SOPA/PIPA) bills aimed at stronger protection of property rights on the Internet. Using a new dataset of U.S. congressmen's public statements, we find a strong statistical relationship between campaign contributions funded by the affected industries and legislators' positions. However, this relationship evaporates once the two bills become primary policy issues. Our results are consistent with the notion that legislators choose positions on secondary policy issues in order to cater to organized interests, whereas positions on primary policy issues are driven by electoral support.

Approval of equal rights and gender differences in well-being

Women earn less than men but are not less satisfied with life. This paper explores whether norms regarding the appropriate pay for women compared to men may explain these findings. We find that the gender wage gap is smaller where a larger fraction of the citizenry has voted in favor of equal pay. We also find that employed women are less (not more) satisfied with life in liberal communities where the gender wage gap is smaller. These findings suggest that norms regarding the appropriate relative pay of women compared to men are shaping gender differences in well-being.     

The use of happiness research for public policy

Research on happiness tends to follow a “benevolent dictator” approach where politicians pursue people’s happiness. This paper takes an antithetic approach based on the insights of public choice theory. First, we inquire how the results of happiness research may be used to improve the choice of institutions. Second, we show that the policy approach matters for the choice of research questions and the kind of knowledge happiness research aims to provide. Third, we emphasize that there is no shortcut to an optimal policy maximizing some happiness indicator or social welfare function since governments have an incentive to manipulate this indicator.     

A Remedy for Kernel Estimation Under Random Design

Two common kernel-based methods for non-parametric regression estimation suffer from well-known drawbacks when the design is random. The Gasser-Müller estimator is inadmissible due to its high variance while the Nadaraya-Watson estimator has zero asymptotic efficiency because of poor bias behavior. Under asymptotic consideration, the local linear estimator avoids these two drawbacks of kernel estimators and achieves minimax optimality. However, when based on compact support kernels its finite sample behavior is disappointing because sudden kinks may show up in the estimate.

This paper proposes a modification of the kernel estimator, called the binned convolution estimator leading to a fast O(n) method. Provided the design density is continously differentiable and the conditional fourth moments exist the binned convolution estimator has asymptotic properties identical with those of the local linear estimator.     

Factors and consequences of a non-functional alary polymorphism inPyrrhocoris apterus (Heteroptera: Pyrrhocoridae)

Functional alary polymorphisms have been studied rather extensively in several insect species. This review article deals with factors controlling wing polymorphism in a flightless species,Pyrrhocoris apterus (L.), and discusses its adaptive significance and mechanisms for their persistence under natural conditions. The macropterous morph is determined by a recessive allele whose penetrance depends on photoperiod and temperature. Natural populations of this species contain a small fraction of flightless macropters. The disadvantages of being a macropter (increase of development time, decrease of fecundity) are minimal, while the benefit may consist in the tendency to prereproductive arrest of ovarian development in teneral females. It prevents establishing a second generation which would mostly die during the next winter. The mechanism of alary morph regulation may be an ancestral trait linkingP. apterus with other polymorphic Heteroptera, while its decreased penetrance may be a derivative character. Variation in fitness due to alary morphs is small compared to the one associated with differences in body size. The latter is environmentally determined, and not linked to the genetic basis of wing polymorphism. In the “mosaic” of phenotypes of various size the significance of the genetic macroptery may be close to neutral.
