The Spanish cadet in the European military context a comparative analysis of the professional socialisation

Research on the attitudes, motivations and social and political behavior of European cadets have been made throughout the last decade. Nowadays Spain also joins those surveys. Thru the analysis of polling data, we can consider the different attitudes of Spanish cadets in relation with the other European ones. The conclusion is that although the Spanish political transition to democracy has not ended already in the military teaching system, there are a lot of similarities among Spanish and European cadets.

Educació en valors i formació docent. La diversitat com a valor

La reflexió sobre la meva pràctica educativa m’ha portat a endinsar-me en el món de la diversitat i de l’educació en valors, i preguntar-me sobre la seva ubicació en la formació docent. L’enfocament d’aquestes qüestions s’ha realitzat des de l’òptica de la persona. Des d’ella s’han buscat uns eixos vertebradors mínims que haurien d’estar presents tant en tot plantejament educatiu concret, com en la legislació en matèria educativa i en els plans de formació del professorat. Aquests eixos vertebradors s’han articulat en una tipologia de valors formada pel valor de la persona, des del qual sorgeixen el valor de l’educació, els valors de la democràcia i el valor de la utopia. El que he realitzat en aquesta recerca ha estat analitzar la legislació educativa i els plans d’estudi de formació de mestres de les universitats de Catalunya a partir de quatre grups d’indicadors que pretenen l’estudi del seu marc contextual, del vocabulari utilitzat –concretament els termes “ètica”, “moral” i “valor”-, del tractament de la diversitat –a partir del territori i la classe social, l’ètnia, el gènere i les necessitats educatives especials-, i de l’enfocament de l’educació en valors –segons la tipologia anteriorment apuntada-.

El descobriment: un context educatiu per implicar els alumnes d'educació primària en l'aprenentatge de la natació

Emmarcat en un context educatiu, la present recerca fa un recorregut teòric per les diferents perspectives que fonamenten els diferents enfocaments de l'ensenyament i aprenentatge de la natació i presenta aquelles estratègies d'ensenyança basades en el descobriment que, fruit de les seves característiques i estructura, poden ser utilitzades per part dels monitors de natació perquè els alumnes s'impliquin cognitivament en els processos d'ensenyament-aprenentatge de la natació. La recerca aprofundeix en la pedagogia del descobriment entenent-la com aquell context educatiu condicionat per l'educador, mitjançant el qual i amb la utilització de les estratègies d'ensenyança pertinents, aquest, a l'hora de presentar les activitats i interaccionar amb els alumnes, pot fomentar el seu protagonisme. Un protagonisme que vindrà marcat per l'aportació personal de cada alumne, d'aquelles respostes descobertes fruit de les decisions preses davant l'estructura de l'activitat presentada, sempre de forma intencionada, pel monitor. D'aquesta manera es promou una implicació i una participació activa dels alumnes en els processos d'aprenentatge de la natació qua ajuda a cercar-ne la significació, en contraposició, a la visió més tradicional del tractament dels cursets de natació i dels seus aprenentatges basats en una pedagogia del model. Una pedagogia en la repetició i automatització d'uns gests presentats pel monitor de natació.

Improving the risk concept: a revision of Arrow-Pratt theory in the context of controlled dynamic stochastic environments

In the literature on risk, one generally assume that uncertainty is uniformly distributed over the entire working horizon, when the absolute risk-aversion index is negative and constant. From this perspective, the risk is totally exogenous, and thus independent of endogenous risks. The classic procedure is "myopic" with regard to potential changes in the future behavior of the agent due to inherent random fluctuations of the system. The agent's attitude to risk is rigid. Although often criticized, the most widely used hypothesis for the analysis of economic behavior is risk-neutrality. This borderline case must be envisaged with prudence in a dynamic stochastic context. The traditional measures of risk-aversion are generally too weak for making comparisons between risky situations, given the dynamic �complexity of the environment. This can be highlighted in concrete problems in finance and insurance, context for which the Arrow-Pratt measures (in the small) give ambiguous.

New York City: "gilt cage" or "promised land" ? : representations of urban space in Edith Wharton and Anzia Yezierska

This thesis explores the importance of literary New York City in the urban narratives of Edith Wharton and Anzia Yezierska. It specifically looks at the Empire City of the Progressive Period when the concept of the city was not only a new theme but also very much a typical American one which was as central to the American experience as had been the Western frontier. It could be argued, in fact, that the American city had become the new frontier where modern experiences like urbanization, industrialization, immigration, and also women's emancipation and suffrage, caused all kinds of sensations on the human scale from smoothly lived assimilation and acculturation to deeply felt alienation because of the constantly shifting urban landscape. The developing urban space made possible the emergence of new female literary protagonists like the working girl, the reformer, the prostitute, and the upper class lady dedicating her life to 'conspicuous consumption'. Industrialization opened up city space to female exploration: on the one hand, upper and middle class ladies ventured out of the home because of the many novel urban possibilities, and on the other, lower class and immigrant girls also left their domestic sphere to look for paid jobs outside the home. New York City at the time was not only considered the epicenter of the world at large, it was also a city of great extremes. Everything was constantly in flux: small brownstones made way for ever taller skyscrapers and huge waves of immigrants from Europe pushed native New Yorkers further uptown on the island, adding to the crowdedness and intensity of the urban experience. The city became a polarized urban space with Fifth Avenue representing one end of the spectrum and the Lower East Side the other. Questions of space and the urban home greatly mattered. It has been pointed out that the city setting functions as an ideal means for the display of human nature as well as social processes. Narrative representations of urban space, therefore, provide a similar canvas for a protagonist's journey and development. From widely diverging vantage points both Edith Wharton and Anzia Yezierska thus create a polarized city where domesticity is a primal concern. Looking at all of their New York narratives by close readings of exterior and interior city representations, this thesis shows how urban space greatly affects questions of identity, assimilation, and alienation in literary protagonists who cannot escape the influence of their respective urban settings. Edith Wharton's upper class "millionaire" heroines are framed and contained by the city interiors of "old" New York, making it impossible for them to truly participate in the urban landscape in order to develop outside of their 'Gilt Cages'. On the other side are Anzia Yezierska's struggling "immigrant" protagonists who, against all odds, never give up in their urban context of streets, rooftops, and stoops. Their New York City, while always challenging and perpetually changing, at least allows them perspectives of hope for a 'Promised Land' in the making. Central for both urban narrative approaches is the quest for a home as an architectural structure, a spiritual resting place, and a locus for identity forming. But just as the actual city embraces change, urban protagonists must embrace change also if they desire to find fulfillment and success. That this turns out to be much easier for Anzia Yezierska's driven immigrants rather than for Edith Wharton's well established native New Yorkers is a surprising conclusion to this urban theme.

The Measurement of social polarization in a multi-group context

Polarization indices presented up to now have only focused their attention on the distribution of income/wealth. However, in many circumstances income is not the only relevant dimension that might be the cause of social conflict, so it is very important to have a social polarization index able to cope with alternative dimensions. In this paper we present an axiomatic characterization of one of such indices: it has been obtained as an extension of the (income) polarization measure introduced in Duclos, Esteban and Ray (2004) to a wider domain. It turns out that the axiomatic structure introduced in that paper alone is not appropriate to obtain a fully satisfactory characterization of our measure, so additional axioms are proposed. As a byproduct, we present an alternative axiomatization of the aforementioned income polarization measure.

Improving the effort concept: a revision of the traditional approach in the context of controlled Dynamic Stochastic Environments

The objective of this paper is to re-evaluate the attitude to effort of a risk-averse decision-maker in an evolving environment. In the classic analysis, the space of efforts is generally discretized. More realistic, this new approach emploies a continuum of effort levels. The presence of multiple possible efforts and performance levels provides a better basis for explaining real economic phenomena. The traditional approach (see, Laffont, J. J. & Tirole, J., 1993, Salanie, B., 1997, Laffont, J.J. and Martimort, D, 2002, among others) does not take into account the potential effect of the system dynamics on the agent's behavior to effort over time. In the context of a Principal-agent relationship, not only the incentives of the Principal can determine the private agent to allocate a good effort, but also the evolution of the dynamic system. The incentives can be ineffective when the environment does not incite the agent to invest a good effort. This explains why, some effici

Govern i planificació de dinàmiques territorials a Catalunya: dos casos d'estudi : Noves respostes a velles lògiques territorials en un context insosteniblement globalitzat

Aquest treball tracta del govern del territori a Catalunya a partir de l’anàlisi d’una experiència europea (Regió metropolitana del Rin-Ruhr a Alemanya) i de l’estudi de dos casos a dos àmbits territorials ben diferents: el Prepirineu de la serra del Cadí per una banda i la Regió Metropolitana de Barcelona per l’altra. L’objectiu principal és analitzar quines formes innovadores de planificació i govern del territori s’estan aplicant i quins efectes estan tenint aquestes. Aquest treball analitza èr una banda dinàmiques territorials crítiques per a Catalunya com els processos de metropolitanització, la crisi industrial o el despoblament rural i per l’altra instruments d’ordenació del territori innovadors com Plans Territorials Parcials, Estratègies Territorials o Plans Estratègics.

Business research, self-fulfilling prophecy, and the inherent responsibility of scholars.

Business research and teaching institutions play an important role in shaping the way businesses perceive their relations to the broader society and its moral expectations. Hence, as ethical scandals recently arose in the business world, questions related to the civic responsibilities of business scholars and to the role business schools play in society have gained wider interest. In this article, I argue that these ethical shortcomings are at least partly resulting from the mainstream business model with its taken-for granted basic assumptions such as specialization or the value-neutrality of business research. Redefining the roles and civic responsibilities of business scholars for business practice implies therefore a thorough analysis of these assumptions if not their redefinition. The takenforgrantedness of the mainstream business model is questioned by the transformation of the societal context in which business activities are embedded. Its value-neutrality in turn is challenged by self-fulfilling prophecy effects, which highlight the normative influence of business schools. In order to critically discuss some basic assumptions of mainstream business theory, I propose to draw parallels with the corporate citizenship concept and the stakeholder theory. Their integrated approach of the relation between business practice and the broader society provides interesting insights for the social reembedding of business research and teaching.

Molecular estimation of dispersal for ecology and population genetics

The dispersal process, by which individuals or other dispersing agents such as gametes or seeds move from birthplace to a new settlement locality, has important consequences for the dynamics of genes, individuals, and species. Many of the questions addressed by ecology and evolutionary biology require a good understanding of species' dispersal patterns. Much effort has thus been devoted to overcoming the difficulties associated with dispersal measurement. In this context, genetic tools have long been the focus of intensive research, providing a great variety of potential solutions to measuring dispersal. This methodological diversity is reviewed here to help (molecular) ecologists find their way toward dispersal inference and interpretation and to stimulate further developments.
