Brother correlations in earnings in Denmark, Finland, Norway and Sweden compared to the United States

The correlation in economic status among siblings is a useful “omnibus measure” of the overall impact of family and community factors on adult economic status. In this study we compare brother correlations in long-run (permanent) earnings between the United States, on one hand, and the Nordic countries (Denmark, Finland, Norway and Sweden) on the other. Our base case results, based on very similar sample criteria and definitions for all countries, show that this correlation is above 0.40 in the United States and in the range 0.14–0.26 in the Nordic countries. Even though these results turn out to be somewhat sensitive to some assumptions that have to be made, we conclude that the family and community factors are more important determinants of long-run earnings in the United States than in the Nordic countries.

How to build social capital with leadership development: Lessons from an explorative case study of a multibusiness firm

The organizational impact of leadership development practices is still not fully understood. Research confirms that in some cases effects can be found and in others not. Most of these attempts search for contribution to a company's human capital. A contribution to social capital development remains an unexplored source of variance in understanding how leadership development impacts organizational performance. This paper therefore explores—from a strategic management perspective—how leadership development practices may contribute to social capital development. We chose the strategic context of a large multibusiness firm in which social capital across business units play an important role for competitive advantage. The exploratory case study reveals that: 1) Social capital differs regarding its intensity and develops through stages characterized by contact, assimilation, and identification experiences. 2) Leadership development practices differ in their potential contribution to social capital development stages and should therefore be designed accordingly.     

Ethnic Groups in Urban Education

The concept of urban education is seen as education conducted under certain conditions and in a particular environment—for example, in inner city areas where immigrant groups have settled. Greek children in State schools in the inner city of Sydney serve as an example. It is suggested that for the local Australian pupils, and for those for whom English is a second language, school entry marks the beginning of their alienation process. Home and school value systems are at variance. The needs of the local Australian group and those of the immigrants are totally separate and disparate. Implications for an effective balance of home and school demands are discussed.     

Interaction Terms in Distance-Based Regression

We propose a method of including polynomial and interaction terms in Distance-Based Regression (Cuadras and Arenas, 1990 Cuadras , C. M. , Arenas , C. ( 1990 ). A distance based regression model for prediction with mixed data . Commun. Statist. A Theor. Meth. 19 : 2261 – 2279 .[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]), relying on properties of a semi-Hadamard or Khatri-Rao product of matrices. We demonstrate its application to real data examples.
