Alleviating Urban Poverty in a Global City: New Trends in Upgrading Rio-de-Janeiro's Favelas

In contrast to the “eradication and resettlement” approach of the 1960s and 1970s, and the implementation of isolated public-works projects in the 1980s, the 1990s in Rio have brought a comprehensive upgrading approach to the favelas. Such local innovations in Brazil began to emerge after the enactment of the 1988 Constitution that gave municipalities the power to formulate urban policies and laws at the local level. We examine the Favela-Bairro Program, in particular, highlighting its five central features: (1) projects designed to integrate favelas with planned neighborhoods (bairros), (2) urban redevelopment plans that embody a comprehensive approach, (3) an emphasis on coordination among municipal agencies, (4) utilization of a participatory approach, and (5) the use of private sector firms in executing public works projects.     

Reconciling Perspectives on Clusters: An Integrative Review and Research Agenda

Although our understanding of clusters and their contribution to economic performance has improved over the last three decades, the literature has become host to a wide array of divergent empirical and theoretical claims. We systematically review cluster studies published in top journals, highlighting the lack of integration among prior work. We focus on the ways in which Porter's three cluster dimensions, namely geography, networks, and institutions, have been utilized. None of the studies reviewed fully captured their complex interrelationships, which we argue is an important cause of the key disagreements in the literature. Configurational theorizing and analysis are presented as means by which the different approaches to cluster studies could be reconciled. We discuss how the application of a configurational approach can help explore new scholarly directions that can deepen our understanding of clusters and their performance‐enhancing potential. In doing so, we can move beyond an understanding of independent effects to emphasizing combinations of attributes that can generate multiple pathways to cluster performance outcomes.     

On the weighted mixed Liu-type estimator under unbiased stochastic restrictions

In this article, we introduce the weighted mixed Liu-type estimator (WMLTE) based on the weighted mixed and Liu-type estimator (LTE) in linear regression model. We will also present necessary and sufficient conditions for superiority of the weighted mixed Liu-type estimator over the weighted mixed estimator (WME) and Liu type estimator (LTE) in terms of mean square error matrix (MSEM) criterion. Finally, a numerical example and a Monte Carlo simulation is also given to show the theoretical results.     

Has Migration Been Beneficial for Migrants and Their Children?

The study compares the social mobility and status attainment of first‐ and second‐generation Turks in nine Western European countries with those of Western European natives and with those of Turks in Turkey. It shows that the children of low‐class migrants are more likely to acquire a higher education than their counterparts in Turkey, making them more educationally mobile. Moreover, they successfully convert this education in the Western European labor market, and are upwardly mobile relative to the first generation. When comparing labor market outcomes of second generations relative to Turks in Turkey, however, the results show that the same level of education leads to a higher occupation in Turkey. The implications of these findings are discussed.     

Patterns of intergenerational mobility of the old and new middle classes in a post-industrial society: Netherlands 1970-2006

It has often been proposed that new cleavages have emerged within the middle class. In this paper, we examine the distinction between social and cultural specialists and technocrats, and investigate whether these new and old middle class fractions are differentiated by their patterns of intergenerational mobility. To what extent do these newly distinguished middle class fractions have specific external and internal intergenerational mobility patterns? And to what extent have mobility boundaries between them been rising over time? To answer these questions, we use 47 Dutch national population sample surveys with detailed occupation codes collected between 1970 and 2006 (N = 60,978). Our analyses of internal and external homogeneity show that the middle class fractions each have characteristic mobility and immobility patterns and therefore a necessary condition is satisfied to declare them as separate classes. Furthermore, in the early periods, the social and cultural specialists were differentiated by a high level of immobility but in the later periods, the distance between the old and new middle classes has decreased significantly.     

Founding family effects on business group growth: Longitudinal evidence from Turkey (1925–2012)

Drawing from the family business perspective, this study provides insights into how the heterogeneity arising from founding family structures explains why particular business groups grow extensively, while others faced with similar external market conditions do not, and how the effects of founding family structure change over time. We test our hypotheses by using a unique, hand-collected, and extensive panel dataset which contains information of the full demographic history of founding families and all public and private companies founded/acquired or divested over the 1925–2012 period for 51 business groups in Turkey. Consistent with our hypotheses, our findings show that family size is a major positive determinant of the number of affiliated firms and the group scope. This effect is more strongly driven by sons compared to daughters. Business groups also grow more extensively when the first-born child is male. These family effects are stronger in the early developmental period of the business groups.     

Occupational burnout and cyberloafing among teachers: Analysis of personality traits,individual and occupational status variables as predictors

One of the phenomena that causes remarkable losses in terms of productivity and cost in organizations is occupational burnout. Burnout is encountered in different occupational groups. However, in professions that are in contact with a large number of people as part of their responsibilities, such as teaching, burnout is a problem that is far more on the foreground. In addition, emotional burnout, which is seen as the first step before occupational burnout, can cause workers to feel insufficient at the point of carrying out tasks related to their duties, leading to behaviour that is out of their fields such as cyberloafing. Addressing this situation in terms of teaching profession, the feeling of inadequacy in educational activities during the course may prevent the teacher from fulfilling any responsibilities while using a device that has internet access. In this context, the aim of this study is to investigate the factors that predict the cyberloafing and burnout levels of teachers working in different fields. This research is a relational research. This research was carried out with the participations of 194 teachers from different branches working in various provinces in Turkey. In this study, a personal information form and three different data collection tools were used. Analysis of the collected data was performed by hierarchical linear multiple regression analysis. The 9 models, created separately with cyberloafing and burnout, were found to be significant in the study. Demographic variables, ICT usage status variables, occupational variables and personality traits were used in these models. Therefore, all the hypotheses included in the research were accepted. As a result of the research, demographic variables were found to be the most important model to predict teachers’ occupational burnout. The most important model explaining teachers’ cyberloafing situations is their ICT usage.     

A Structure Theorem for Rationalizability with Application to Robust Predictions of Refinements

Rationalizability is a central solution concept of game theory. Economic models often have many rationalizable outcomes, motivating economists to use refinements of rationalizability, including equilibrium refinements. In this paper we try to achieve a general understanding of when this multiplicity occurs and how one should deal with it. Assuming that the set of possible payoff functions and belief structures is sufficiently rich, we establish a revealing structure of the correspondence of beliefs to sets of rationalizable outcomes. We show that, for any rationalizable action a of any type, we can perturb the beliefs of the type in such a way that a is uniquely rationalizable for the new type. This unique outcome will be robust to further small changes. When multiplicity occurs, then we are in a “knife‐edge” case, where the unique rationalizable outcome changes, sandwiched between open sets of types where each of the rationalizable actions is uniquely rationalizable. As an immediate application of this result, we characterize, for any refinement of rationalizability, the predictions that are robust to small misspecifications of interim beliefs. These are only those predictions that are true for all rationalizable strategies, that is, the predictions that could have been made without the refinement.
