La Funcion del Bostezo en la Comunicacion Social de un Grupo de Babuinos

Resumen

La adecuación entre el perfil que ofrecen las mujeres altamente cualificadas que quieren acceder a puestos de dirección y la demanda de las organizaciones de un comportamiento directivo, horizontal y centrado en las personas, alternativo al que impera en la actual cultura empresarial, es el punto de partida del presente estudio. Diversas teorías asocian el estilo directivo transformacional con características prototípicamente femeninas. Este trabajo se plantea dos propósitos. Por un lado, comprobar en una amplia muestra representativa de hombres y mujeres que desempeñan puestos de dirección si existen diferencias en su estilo directivo; y por otro lado, si es así, analizar su correspondencia con los estilos transaccionaly transformational a partir del cuestionario de liderazgo de Bass y Avolio. La interpretación de los resultados demuestra la necesidad de fomentar la incorporación de las mujeres a cargos de dirección, no únicamente por razones humanitarias basadas en la igualdad de derechos y oportunidades, sino por la contribución del estilo directivo femenino a la eficacia organizational.     

Reconocimiento de emociones a partir de descripciones verbales

Resumen

El presente estudio supone una aplicación tentativa de la técnica del autoinforme a la codificación y decodificación de las manifestaciones corporales y expresivas asociadas al comportamiento emocional. El interés en el uso de dicha técnica radica, no tanto en la posibilidad de determinar los cambios reales asociados a la emoción, como de conocer el modo en que los sujetos recuerdan y categorizan su experiencia emocional.     

How Objects Believe for Us: Applications in Organizational Analysis

This paper analyzes the concept of belief in contemporary organizations. Most studies tend to envisage belief as something internal to the thinking and feeling person. We argue, however, that belief does not only reside ‘inside’ the individual subject but also in an external economy of objects and rituals. What we call the ‘objectivity of belief’ highlights how various things such as commodities, artefacts, machines and even other people may believe in our place. We develop these ideas by drawing on a rich tradition of social theory that includes Marx and ?i?ek, and apply it to the study of objects, belief and power in contemporary organizations.     

Multidimensional Measurement of Poverty Among Women in Sub-Saharan Africa

Since the seminal work of Sen, poverty has been recognized as a multidimensional phenomenon. The recent availability of relevant databases renewed the interest in this approach. This paper estimates multidimensional poverty among women in fourteen Sub-Saharan African countries using the Alkire and Foster multidimensional poverty measures, whose identification method is based on a counting approach. Four dimensions are considered: assets, health, schooling and empowerment. The results show important differences in poverty among the countries of the sample. The multidimensional poverty estimates are compared with some alternative measures such as the Human Development Index, income poverty, asset poverty and the Gender-related Development Index. It is found that including additional dimensions into the analysis leads to country rankings different from those obtained with the mentioned four measures. Decompositions by geographical area and dimension indicate that rural areas are significantly poorer than urban ones and that a lack of schooling is, in general, the highest contributor to poverty. The paper also conducts robustness and sensitivity analyses of the multidimensional estimates with respect to the number of dimensions in which deprivation is required in order to be considered poor, as well as to the poverty lines within each dimension. Several cases of dominance between countries are found in the first robustness test.     

How Cognitive Interviewing can Provide Validity Evidence of the Response Processes to Scale Items

The current theory about validity reflected in the Standards for Educational and Psychological Testing (AERA et al. in Standards for educational and psychological testing, American Psychological Association, Washington, DC, 1999), offers no clear indications about the methods for gathering validity evidence about the response processes. Cognitive interviewing (CI) can play an important role answering the current demand about empirical and theoretical analyses of the response processes as a source of validity evidence in psychological testing. CI can provide validity evidence for investigating substantive aspects of construct validity and for contributing to the explanations for item and test scores (Zumbo in Handbook of statistics, vol 26, Elsevier, Amsterdam, pp. 45–79, 2007; The concept of validity: revisions, new directions and applications, IAP—Information Age Publishing Inc., Charlotte, NC, pp. 65–82, 2009). The aim of the study was to illustrate the use of cognitive interviewing method for gathering validity evidence on response processes. The search for evidence about the “response process” was guided by an argument-based approach to validity (Kane in Psychological Bulletin 1992; Educational measurement, American Council on Education/Praeger, Washington, DC, pp. 17–64, 2006). 21 cognitive interviews were carried out during the cognitive testing of the APGAR psychological scale intended to measure the “family support” construct. Cognitive interviewing provided validity evidence that explains how respondents interpret and respond to the APGAR items. Respondents maintained a shared interpretation of “family concept” while answering the APGAR scale items. Nevertheless, they included in the concept of family not only family members they live with but also other family members and even friends. CI participants were also capable of classifying their answers about the family support perception following a polythomous response system. Lastly, the role of CI in the Kane’s argument-based approach and Zumbo’s contextualized view of validity will be discussed.     

A note on “Re-examining the law of iterated expectations for Choquet decision makers”

This note completes the main result of Zimper (Theory and decision, doi:10.1007/s11238-010-9221-8, 2010), by showing that additional conditions are needed in order the law of iterated expectations to hold true for Choquet decision makers. Due to the comonotonic additivity of Choquet expectations, the equation E[f, ν(dω)] = E[E[f(ω _{i, j} ), ν(A _{i, j} |A _i )], ν(A _i )], is valid only when the act f is comonotonic with its dynamic form, that we name “conditional certainty equivalent act”.     

Environmental effects on affect: Density,noise and personality

Approximation of molar crowding found in urban centers was studied by using a 2 × 2 × 2 × 2 factorial design. The study involved the simultaneous variation of social density, spatial density, noise, and personality as they affect room affect (physical and psychological). Subjects were 88 undergraduate males pre-tested on the Rotter I-E scale. Other measures used were Marshall's Privacy Preference and Noise Tolerance scales. A scale of Perceptions of the Room was also administered. Results showed main effects of locus of control and spatial density on overall room affect. A Noise × Density interaction approached significance with respect to physical room affect. A main effect of spatial density on physical room affect was also found. Psychological room affect was influenced by spatial density. Theoretical explanations of the results are discussed in terms of dissonance theory, Altman's Social Interaction Model, and the authors' extension of the Worchel and Teddlie two-step model of crowding. It is suggested that introduction of the concept of "appropriate" or "dissonant" space might explain these results and add to our understanding of crowding.Reprint requests should be directed to Ms. Bharucha-Reid.     

Impact of funding and value added on Spanish venture capital-backed firms

This paper contributes to the literature on the effect of venture capital (VC) on the economic development of areas in which those specialized investors are active. The work focuses on the separate consideration of two effects that are supposed to explain the superior performance of a large sample of Spanish VC-backed firms, namely funding and value-added services provided by VC managers to their investee firms. The results show that funding is significant regardless of the stage of development of the investee firm. The value added, however, is only significant for the subsample of firms at the expansion stage.     

Speed in the Internationalization Process of the Firm

While firm internationalization processes have been understood as being dynamic, the dimension of speed has rarely been the main focus of research efforts, which, until a decade ago, focused principally on explaining sequences of entry modes and choices of markets. The emergence of the study of international entrepreneurship has enhanced the role of speed, although this has usually been measured in terms of the time lag between a firm's foundation and its initial international action, with little attempt at defining and explaining the speed of the process once it is under way. This study reviews the concept of speed from an internationalization perspective, describes the multidimensional nature of the concept and sets out the different aspects that link timescales with the types of changes – continuous and discontinuous – that take place during internationalizing processes. The paper concludes with a research agenda as a guide for future work on considering the role of speed in the internationalization process.     

Inter-firm collaborations and supply chain coordination: review of key elements and case study

Considering the effects of globalisation, the increase of production and energy costs, and the introduction of advanced technologies, companies need to change their way of doing business if they want to stay competitive. One way of doing this is to establish collaborations with suppliers, distributors and retailers, in order to exchange products efficiently and create value for customers. Nevertheless, the structure of the collaboration must be designed carefully and some coordination mechanisms must be implemented to support this way of doing business. In this article, we first analyse: why companies work together, how they should build their partnership, and which strategies they can implement to facilitate coordination of supply chain activities. We then report a case study of collaboration in the forest industry that shows the benefits of implementing coordination mechanisms as well as the necessity of using incentives to better share these benefits.
