Developing the eclectic paradigm as a model of global strategy: An application to the impact of the Sep. 11 terrorist attacks on MNE performance levels

We expand the eclectic paradigm into a model of global strategic management and apply the latter to the analysis of the impact of the Sep. 11th terrorist attacks on the MNEs' performance to investigate the effect of exogenous shocks on the global strategies of firms. First, we integrate MNE resources and capabilities, strategy, and structure with the eclectic paradigm. Then we focus specifically on location attractiveness to examine how MNEs adjust internal factors with the exogenous distortions caused by an extreme environmental shock. We suggest that this adjustment is carried out at four levels: resources and capabilities, strategy, structure, and choice of location which jointly determine MNEs' performance. Although we restrict the application of this model of global strategic management to the post-Sep. 11th, our model may be applied to other extreme events that change, at least partly, the worldwide, or regional, economic order.     

An alpha-power extension for the Birnbaum–Saunders distribution

Data on fatigue to exceed a critical value (or to grow to a critical level at which failure is likely to occur) is typically adjusted using the Birnbaum–Saunders (BS) distribution [see Birnbaum ZW, Saunders SC. A new family of life distributions. J Appl Probab. 1969a;6:319–327]. Although this type of distribution is asymmetric, in some cases the degree of skewness and/or kurtosis are outside the distributional range allowed by the BS distribution. Thus, a more adequate distribution model for better adjusting such unexpected deviations is called for. With this in mind, the main object of this paper is to propose an extension of the BS distribution based on the asymmetric alpha-power family of distributions [see Pewsey A, Gómez HW, Bolfarine H. Likelihood-based inference for power distributions. Test. 2012;21(4):775–789]. This extension is called the exponentiated BS distribution. We expect that by replacing the normal distribution by such more general family, a more flexible BS family is obtained. Asymmetry in the alpha-power family is controlled by a shape parameter, which also presents a similar performance in the extended BS family. The paper presents the density function for the extended BS and derives closed-form expressions for moments. Estimation is dealt with by using maximum likelihood estimators. Large sample inference can be conducted by using the Fisher information matrix derived in the paper. Estimation performance is studied by using a small scale simulation study. Results of a real application illustrates the good performance of the proposed approach.     

The Alpha-power Tobit Model

The main object of this article is to propose an extension of the tobit model for which the error distribution follows the power-normal distribution (Gupta and Gupta, 2008 Gupta , D. , Gupta , R. C. ( 2008 ). Analyzing skewed data by power normal model . Test 17 : 197 – 210 .[Crossref], [Web of Science ®] , [Google Scholar]). Inference is dealt with by using the likelihood approach. Simulation studies and application to a real data set are used to demonstrate the usefulness of the extension.     

A Unified Approach To The Myerson Value And The Position Value

We reconsider the Myerson value and the position value for communication situations. In case the underlying game is a unanimity game, we show that each of these values can be computed using the inclusion--exclusion principle. Linearity of both values permits us to calculate them without needing the dividends of the induced games (graph-restricted game and link game). The expression of these dividends is only derived in the existing literature for special communication situations. Moreover, the associated inclusion--exclusion decomposability property depends on what we have called the graph allocation rule. This rule is the relative degree (relative indicator) for the position value (Myerson value).     

Identity and the developmental origins of fusion: an exploratory approach / La identidad y los orígenes de la fusión en el desarrollo: un enfoque exploratorio

Abstract

Identity fusion involves a visceral feeling of oneness with a group, despite personal and social selves remaining differentiated. Previous research on identity fusion has focused on samples of adults and adolescents. The present studies aim at exploring how and when identity fusion develops in childhood. Our first goal was to find out to what extent personal and social identities must be developed for fusion to become possible. We conducted two exploratory studies where school-age children (six to 12 years old) participated in either focus group sessions or individual interviews. Our results show that although children are able to feel strongly connected with a group and express willingness to make significant personal sacrifices for the group, they fail to show fusion as it is found in adults, since their personal identity is not fully developed yet. Instead, these findings suggest the existence of a prior feeling that we called ‘protofusion’, the core of which is the strength of the relational ties with the members of the group.

Income and Beyond: Multidimensional Poverty in Six Latin American Countries

This paper studies multidimensional poverty for Argentina, Brazil, Chile, El Salvador, Mexico and Uruguay for the period 1992–2006. The approach overcomes the limitations of the two traditional methods of poverty analysis in Latin America (income-based and unmet basic needs) by combining income with five other dimensions: school attendance for children, education of the household head, sanitation, water and shelter. The results allow a fuller understanding of the evolution of poverty in the selected countries. Over the study period, El Salvador, Brazil, Mexico and Chile experienced significant reductions in multidimensional poverty. In contrast, in urban Uruguay there was a small reduction in multidimensional poverty, while in urban Argentina the estimates did not change significantly. El Salvador, Brazil and Mexico, and rural areas of Chile display significantly higher and more simultaneous deprivations than urban areas of Argentina, Chile and Uruguay. In all countries, deprivation in access to proper sanitation and education of the household head are the highest contributors to overall multidimensional poverty.     

Evaluation of what parents know about their children's drug use and how they perceive the most common family risk factors

Research on family risk factors for addictive behaviors in young people has not paid a great deal of attention to parents' knowledge of their children's addictive behaviors and of the family risk factors that affect such behaviors. The aim of this work is to compare knowledge about these two aspects in two groups of parents that differ regarding their children's declared drug use. The research was carried out with a sample of 309 schoolchildren and their families, divided into two groups: one of 154 families with children defined as non-Drug Users and another of 155 families with children defined as Drug Users. The results show that parents with children who consume drugs tend to strongly underestimate their children's use. Moreover, they overestimate the control they exercise over them and appear to be more familiarized with the use of drugs, if we compare them with parents of non-Drug Users. It is suggested that these results may be relevant for the planning of strategies that increase motivation in families with drug-risk children to participate in prevention programs.
