The role and effect of controlling shareholders in corporate governance

This paper examines two potentially contradictory effects of the presence of controlling shareholders. Controlling shareholders have been shown to be beneficial, as they generally have a long-term interest in the firm and are willing and able to monitor the actions of senior managers closely and decrease agency costs between shareholders and management (agency costs of Type I). However, they are also in a position to expropriate the firm’s assets, especially when they are actively involved in management (agency costs of Type II). More specifically, this article reviews how regulatory and legislative bodies have tried to curb the consumption of private benefits by controlling shareholders while preserving the beneficial aspects of their long-term interest and their monitoring role, the effect controlling shareholders on the application and effectiveness of corporate governance best practices as well as on the executive and board member remuneration.     

Sociology,narrative, and the quality versus quantity debate (Goethe versus Newton): Can computer-assisted story grammars help us understand the rise of Italian fascism (1919–1922)?

At the heart of this article is a structural approach to narrative, based on the work of Propp, Labov, van Dijk, Halliday, and others. The article highlights the structural features of narrative—basically, the organization of the genre around the semantic template actor-action-actor (syntactically rendered as subject-verb-object but where, in narrative, the subject is typically a social actor and the verb a social action) and the modifiers of each element of this triplet, such as time and space of action—and shows how to implement this structure in a computer environment and how to use this methodological tool in socio-historical research (namely, the rise of Italian fascism, 1919–22). But, taking a cue from Halliday’s cover jacket of his An Introduction to Functional Grammar, with its representation of a color circle, the paper takes the reader on an intellectual journey from Newton to Goethe—and the quality versus quantity debate—to Goethe and Propp, to end, back home, with Simmel and Weber.     

Green supply management and performance: a resource-based view

Abstract

This study develops and empirically tests, from the resource-based perspective, a conceptual framework linking green supply management and performance. The proposed model is tested using data from a sample of 126 automotive manufactures in China. The results suggest that both green purchasing personnel and green supplier selection have a significant positive effect on green supplier collaboration, and that building green collaboration with suppliers is significantly and positively related to both environmental and operational performance. Accordingly, knowledge and skill development of the purchasing function can be recognised as an important resource in building green supply capabilities and performance.     

Prevalence of Problem Gambling Among Adolescents: A Comparison Across Modes of Access,Gambling Activities,and Levels of Severity

The high availability and accessibility of online gambling have recently caused public concern regarding the potential increase of gambling-related problems among young people. Nonetheless, few studies among adults and none among adolescents have explored specific characteristics of gamblers as a function of gambling venues to date. This study sought to analyze the prevalence of gambling among a sample of adolescents in the last year, as well as sociodemographic and gambling-related characteristics as possible predictors of at-risk and problem gambling. The sample comprised 1313 adolescents aged 14–18 years. Participants were asked to respond to several questions regarding their gambling behavior. Chi square and ANOVA tests were performed in order to explore differences between groups, and a set of multinomial regressions established significant severity predictors. The prevalence of at-risk and problem gambling was 4 and 1.2 %, respectively. Regression analyses showed that having a relative with gambling problems predicted at-risk gambling. Both living with only one parent or not living with parents at all, and the prevalence of Electronic Gambling Machines in the last year were associated with problem gambling. Mixed-mode gambling was a predictor of both at-risk and problem gambling. Our findings extend previous research on gambling among adolescents by exploring gambling behavior according to different modes of access. Although the prevalence of exclusive online gambling among the total sample was low, these results support the need to consider specific subgroups of gamblers and their concrete related features when conducting both indicated prevention and treatment protocols for adolescents.     

Older women who experience mistreatment:circumstances and outcomes

Data from Virginia Adult Protective Services (APS) case files of 95 abused women aged 60 years and older were assessed to establish demographic trends; ability to care for self; type, pattern, and place of abuse; information on witnesses and alleged offenders; and case resolution and outcomes. The most common types of mistreatment reported were neglect, exploitation, and physical abuse. The women typically had several functional limitations and were dependent upon their family members for care. Most cases were not prosecuted, and the majority of women remain at risk for further abuse. Implications of these data for future research and practice are discussed.     

Decomposing Bayesian networks: triangulation of the moral graph with genetic algorithms

In this paper we consider the optimal decomposition of Bayesian networks. More concretely, we examine empirically the applicability of genetic algorithms to the problem of the triangulation of moral graphs. This problem constitutes the only difficult step in the evidence propagation algorithm of Lauritzen and Spiegelhalter (1988) and is known to be NP-hard (Wen, 1991). We carry out experiments with distinct crossover and mutation operators and with different population sizes, mutation rates and selection biasses. The results are analysed statistically. They turn out to improve the results obtained with most other known triangulation methods (Kjærulff, 1990) and are comparable to results obtained with simulated annealing (Kjærulff, 1990; Kjærulff, 1992).     

Democratic transitions and the semiperiphery of the world-economy

The dramatic global transition to democracy of the last decade reveals important systematic patterns. Using recent contributions to world-systems theory, this study examines the relationship between political regime changes and the position of nations in the world-economy over the last two decades, to argue that democratic transitions have been centered among semiperipheral nations. The study also found a strong relationship between the structure of the labor force and the global distribution of democratic institutions, but a weak relationship between the structure of the labor force and the timing of transitions in the semiperiphery. Overall, the findings suggest that world-systemic categories provide a useful vantage point to distinguish global trends from the specific characteristics of individual nations, thereby allowing for greater analytical precision in identifying the crucial causal relations shaping transitions from dictatorship to democracy.     

A class of log-linear models with constrained marginal distributions

Summary In the log-linear model for bivariate probability functions the conditional and joint probabilities have a simple form. This property make the log-linear parametrization useful when modeling these probabilities is the focus of the investigation. On the contrary, in the log-linear representation of bivariate probability functions, the marginal probabilities have a complex form. So the log-linear models are not useful when the marginal probabilities are of particular interest. In this paper the previous statements are discussed and a model obtained from the log-linear one by imposing suitable constraints on the marginal probabilities is introduced. This work was supported by a M.U.R.S.T. grant.     

A general maximum likelihood analysis of measurement error in generalized linear models

This paper describes an EM algorithm for maximum likelihood estimation in generalized linear models (GLMs) with continuous measurement error in the explanatory variables. The algorithm is an adaptation of that for nonparametric maximum likelihood (NPML) estimation in overdispersed GLMs described in Aitkin (Statistics and Computing 6: 251–262, 1996). The measurement error distribution can be of any specified form, though the implementation described assumes normal measurement error. Neither the reliability nor the distribution of the true score of the variables with measurement error has to be known, nor are instrumental variables or replication required.Standard errors can be obtained by omitting individual variables from the model, as in Aitkin (1996).Several examples are given, of normal and Bernoulli response variables.     

The Influence of The People of Puerto Rico Project on Mexican Anthropology

In the 1970s in Mexico, anthropological regional projects were designed to explore new research interests: irrigation works, peasants, rural capitalism, and mines. Julian H. Steward, Eric R. Wolf, and Sidney W. Mintz, participants in the research project on Puerto Rico, were all popular authors among the new generation of anthropologists and were frequently cited in their thesis bibliographies. This article explores the influence of the People of Puerto Rico project at the design level of these new collective and regional projects. Students were distributed within larger areas, covering various climatic and production subareas, in their research training. The important role of cities, industries, haciendas, markets, and government programs was highlighted. I suggest that senior anthropologists and academic leaders who were planning this new anthropological era were more familiar than their students with the conceptual lines of the Puerto Rico Project. I gained greater insight into the difficulties of a regional research enterprise when I did anthropological research in the 1980s at the Tennessee Valley project.
