Strategic and Organizational Evolution of Spanish Firms: Towards a Holding Network Form?

The main objective of this study is to analyse the strategic and organizational evolution of large firms in a current time period and within a specific geographical context (Spain). In order to achieve this purpose, the paper combines the Chandlerian programme with processual analysis. We draw on documentary sources (annual reports, company histories, business directories and so on) and interviews. We have found that in the model of corporate development some characteristics of new organizational structures will coexist with some features of old ones. In line with previous studies our findings highlight the existence of the 'multidivisional network' but, most importantly, our findings also reflect the emergence of a new kind of organizational form that we call 'holding network'. The 'holding network' is more decentralized, both strategically and operationally, than the multidivisional form. However, its level of decentralization is less than in the N-form. Furthermore, whereas the multidivisional form is a hierarchy, the 'holding network' emphasizes the communication among people of different levels. This multilevel communication differs from that in the N-form. Apart from the horizontal communication in the same level there is vertical and horizontal communication between different levels. We conclude by emphasizing the need to explore in future empirical studies to what extent these patterns and new organizational forms should be considered as a transitory or consolidated phenomenon.     

The Socioemotional Well-Being Index (SEWBI): Theoretical Framework and Empirical Operationalisation

This article presents the design, process of construction, content and validation of the Socioemotional Well-Being Index. This index is a composite indicator of subjective well-being, and has been designed with the aim of providing a measurement device for the sociological analysis of the subjective components of quality of life and social quality. Two spheres of knowledge have been combined in its construction: research in social indicators, the recent development of which has been oriented toward the elaboration of composite indicators, and the theoretical content developed in recent decades by the sociology of emotions. As a composite indicator, the index presented in this article offers a hierarchical and multidimensional alternative to the univariate scales measuring happiness and satisfaction most often used in social research. In addition, in comparison to measures of subjective well-being grounded in cognitive evaluations, this index is based on the evaluation of a series of emotional states recently experienced by individuals. The conceptual definition of socioemotional well-being is based on Thomas Kemper’s social interactional theory of emotions and Randall Collins’ theory of interaction ritual chains. A “4 factor, 10 variable” solution has been obtained by applying common factor analysis to the data of the European Social Survey, 2006.     

A Note on Bias of Closed-Form Estimators for the Gamma Distribution Derived From Likelihood Equations

We discuss here an alternative approach for decreasing the bias of the closed-form estimators for the gamma distribution recently proposed by Ye and Chen in 2017. We show that, the new estimator has also closed-form expression, is positive, and can be computed for n?>?2. Moreover, the corrective approach returns better estimates when compared with the former ones.     

FOOLING MYSELF OR FOOLING OBSERVERS? AVOIDING SOCIAL PRESSURES BY MANIPULATING PERCEPTIONS OF DESERVINGNESS OF OTHERS

We present a novel experiment demonstrating strategies selfish individuals utilize to avoid social pressure to be altruistic. Subjects participate in a trust game, after which they have an opportunity to state their beliefs about their opponent's actions. Subsequently, subjects participate in a task designed to “reveal” their true beliefs. Subjects who initially made selfish choices falsely state their beliefs about their opponent's kindness. Their “revealed” beliefs were significantly more accurate, which exposed subjects' knowledge that their selfishness was unjustifiable by their opponent's behavior. The initial false statements complied with social norms, suggesting subjects' attempts to project a more favorable social image. (JEL C9, D03, D83)     

Being Mapuche today in Chile: judgement criteria for ethnic identification among the new generation

This study seeks to identify the underlying factors that sustain ethnic identification judgements – in this case regarding the Mapuche ethnic group – elaborated by a sample of Chilean young people who live in the Santiago metropolitan region. To this end a factorial survey method was used, incorporating quasi-experimental vignettes, which demonstrate social and individual determinants of human judgements. The results show that both self-identification as Mapuche and last name – particularly the paternal surname – are the criteria considered most relevant to inform judgements about ethnic identity. It is clear that there is a complex idea about what it means to be Mapuche today among young people in Chile, combining both subjective and objective factors. This conjunction shows the narrowness of the constructivist and essentialist proposals for understanding ethnicity.     

Negotiating Partnerships in Research on Poverty With Community-Based Agencies

This article argues that researchers must negotiate true partnerships with poor women, maintain mutual support systems, and build mutual respect, if they are to have success in challenging poverty through research. The experience of establishing partnerships with community-based agencies is discussed and the rationale for including poor women in partnerships is considered in terms of the benefits and the challenges for researchers. Among the critical issues are problems of difference, including ethnicity, social class, and gender and relationships between researchers and participants. These issues are highlighted using two examples. A negative outcome from noncollaboration is represented by the case of an after-school program in an inner-city school. The failure to establish collaboration leads to disappointing results. A successful case is described by the cooperative efforts between researchers and poor women in a program for substance abuse. Several strategies and recommendations are offered in conclusion.     

An integer programming framework for critical elements detection in graphs

This study presents an integer programming framework for minimizing the connectivity and cohesiveness properties of a given graph by removing nodes and edges subject to a joint budgetary constraint. The connectivity and cohesiveness metrics are assumed to be general functions of sizes of the remaining connected components and node degrees, respectively. We demonstrate that our approach encompasses, as special cases (possibly, under some mild conditions), several other models existing in the literature, including minimization of the total number of connected node pairs, minimization of the largest connected component size, and maximization of the number of connected components. We discuss computational complexity issues, derive linear mixed integer programming (MIP) formulations, and describe additional modeling enhancements aimed at improving the performance of MIP solvers. We also conduct extensive computational experiments with real-life and randomly generated network instances under various settings that reveal interesting insights and demonstrate advantages and limitations of the proposed framework.
