WAGE DISCRIMINATION ACROSS ETHNIC GROUPS: EVIDENCE FROM ISRAEL

We investigate wage differentials between ethnic groups in Israel, proposing a new methodology and an illustration based on the latest Israeli census. By using separate wage equations for the various occupations, our methodology allows us to decompose the wage differential into three components: one reflecting human capital differences; one reflecting wage discrimination; and a third indicating occupational segregation. We find that 70 percent of the wage gap is due to segregation, 26 percent to wage discrimination and only 4 percent to human capital differences. Evidence is also found for the existence of duality in the Israeli labor market.     

Mathematische aspekte zu einer methode zur numerischen bestimmung individueller thermodynamischer aktivitätskoeffizienten einzelner ionensorten in konzentrierten elektrolytlösungen

The mathematical problems of the – in an communication [3] described – principle for the calculation of individual thermodynamic activity coefficients of single ionic species in concentrated electrolyte solutions are specified. It is the Newtonian approximation method that makes possible the evaluation of the constants b ₁,…b ₄ in the concentration function (0.1) for the product of the activity coefficients.

The efficiency of the method is represented by the example of the activity coefficients of pure and of – with other electrolytes – mixed solutions of NaCIO₄. The individual activity coefficients of the single ionic species are evaluated for several electrolytes of the concentration range from m = 0 to m = 10 mole/kg and published at another place [3, 17, 18].     

Critical Literacy as a Lens for Students’ Evaluation of Sources in an AP World History Class

Abstract

Critical literacy is an appropriate learning outcome for social studies courses because it has the potential to teach students how to critically evaluate sources of information relevant to historical texts and current news media. The purpose of this qualitative case study is to examine the process through which students learned to apply critical literacy strategies while completing an end-of-unit research project in tenth grade AP world history. This study looks as student and teacher interviews to examine how students use critical literacy approaches and perspectives to analyze texts. As a result of this study it was determined that: (1) students at the elite private school had limited experience with source evaluation and critical literacy prior to this research project, (2) critical literacy served as an effective evaluation tool for reliability and bias for some students, (3) certain students experienced challenges in using critical literacy as an evaluation tool, and (4) students believed that critical literacy would benefit them personally and academically. Results include implications for instructors who wish to teach critical literacy and source evaluation in this information age.     

Wage Mobility in Israel: The Effect of Sectoral Concentration

Using a unique eight-year data set, merging population census and national insurance data, the paper examines and compares patterns of wage mobility in Israel. First, the public and the private sectors are compared. Second, within each of these sectors, a distinction is made between sub-sector groupings that exhibit a high level of concentration and those that are more diffuse and unregulated. Based on alternative measures of wage mobility, the central finding of the paper is that the extent of wage mobility in a given economic sector is negatively related to the degree of concentration in that sector.     

Source country culture and labor market assimilation of immigrant women in Sweden: evidence from longitudinal data

This paper analyzes the role of source country culture on gender roles for labor market assimilation of immigrant women in Sweden. Sweden ranks as one of the world’s most gender-equal countries and at the same time a recipient of many immigrants from countries with more traditional views on gender roles and gender equality. I find that the labor force participation of immigrant women in Sweden is related to their source country culture, in the sense that women from countries where women’s labor market participation is low (high) also have low (high) participation in the Swedish labor market. However, all immigrant women assimilate towards, but do not reach parity with, the participation rate of native women, and the difference between women from high- and low-participation countries diminishes with length of residence in Sweden. This indicates that source country culture on gender roles does not have a persistent effect on immigrant women’s labor market participation in Sweden. Furthermore, the results highlight the importance of taking into account unobservable time-constant individual and source country factors when estimating the relationship between source country culture and immigrants’ labor market outcomes. Neglecting to control for these factors could lead researchers to misrepresent the rate of assimilation and overstate the effect of source country culture.     

Wage Decompositions with Selectivity-Corrected Wage Equations: A Methodological Note

This paper examines the implications of the standard Heckman (Heckit) correction for selectivity bias in wage and earnings functions that are subsequently used in wage decompositions. Even when justified, Heckit selectivity correction introduces some fundamental ambiguities in the context of wage decompositions. The ambiguities arise from group differences in the selection term which consists of a parameter multiplied by the Inverse Mills Ratio (IMR). The parameter is identified as the product of the standard deviation of the errors in the wage equation and the correlation between the wage equation error and the selection equation error. How should group differences in these parameters be interpreted in terms of structural differences and endowment effects? The same issue arises with respect to group differences in the IMR which reflect nonlinear group differences in the determinants of selection and in the probit coefficients.     

COMPETING PERSPECTIVES ON CROSS-NATIONAL CRIME: AN EVALUATION OF THEORY AND EVIDENCE

Cross-national studies of crime are dominated by a Durkheimian-Modernization theoretical perspective. We evaluate this perspective and present two alternatives, the Marxian-World System and Ecological-Opportunity perspectives. Each is for its theory of social change, causal explanation of criminal behavior, conceptualization of law and crime rates, and view of the relation between collective political behavior and crime. The empirical evidence is assessed and weak support is found for the dominant perspective. The article concludes by reconsidering the concepts of economic development and crime rates.     

The evolution of secularization: cultural transmission, religion and fertility—theory, simulations and evidence

This study presents an evolutionary process of secularization assuming that cultural/social/religious norms (in particular the ‘religious taste for children’) are transmitted from one generation to the next via two venues: (i) direct socialization—across generations, by parents; and (ii) oblique socialization—within generations, by the cultural environment. The paper integrates a theoretical model, simulations and an empirical estimation, that lead to the following main findings: (i) direct religious socialization efforts of one generation have a negative effect on secularization within the next generation; (ii) oblique socialization by the community has a parabolic effect on secularization; and (iii) the two types of socialization are complementary in ‘producing’ religiosity in the next generation.     

Evaluation utilization research-Developing a theory and putting it to use

This article presents the findings of a two-stage study that had two key objectives: to develop a theory about evaluation utilization in an educational organization and to apply this theory to promote evaluation utilization within the organization. The first stage involved a theoretical conceptualization using a participatory method of concept mapping. This process identified the modes of evaluation utilization within the organization, produced a representation of the relationship between them and led to a theory. The second stage examined the practical implications of this conceptualization in terms of how different stakeholders in the organization perceive the actual and preferable state of evaluation utilization within the organization (i.e. to what extent is evaluation utilized and to what extent should it be utilized). The participatory process of the study promoted the evaluation utilization by involving stakeholders, thus giving them a sense of ownership and improving communication between the evaluation unit and the stakeholders. In addition, understanding the evaluation needs of the stakeholders in the organization helped generate relevant and realizable evaluation processes. On a practical level, the results are currently shaping the evaluation plan and the place of evaluations within the organization.     

Structure and bias in the network autocorrelation model

In a recent paper (Mizruchi and Neuman, 2008), we showed that estimates of ρ in the network autocorrelation model exhibited a systematic negative bias and that the magnitude of this bias increased monotonically with increases in network density. We showed that this bias held regardless of the size of the network, the number of exogenous variables in the model, and whether the matrix W was normalized or in raw form. The networks in our simulations were random, however, which raises the question of the extent to which the negative bias holds in various structured networks. In this paper, we reproduce the simulations from our earlier paper on a series of networks drawn to represent well-known structures, including star, caveman, and small-world structures. Results from these simulations indicate that the pattern of negative bias in ρ continues to hold in all of these structures and that the negative bias continues to increase at increasing levels of density. Interestingly, the negative bias in ρ is especially pronounced at extremely low-density levels in the star network. We conclude by discussing the implications of these findings.
