The ‘Global Dimension’ of Contemporary Politics. An Argument for Taking ‘Global’ Seriously

Recent years have seen a striking proliferation of the term ‘global’ in public and political discourse. The popularity of the term is a manifestation of the fact that there is a widespread notion that contemporary social reality is ‘global’. The acknowledgment of this notion has important political implications and raises questions about the role played by the idea of the ‘global’ in policy making. These questions, in turn, expose even more fundamental issues about whether the term ‘global’ indicates a difference in kind, even an ontological shift, and, if so, how to approach it. This paper argues that the notion of ‘global’, in other words the ‘global dimension’, is a significant aspect of contemporary politics that needs to be investigated. The paper argues that in the globalization discourse of International Studies ‘global’ is ‘naturalized’, which means that it is taken for granted and assumed to be self-evident. The term ‘global’ is used mainly in a descriptive way and subsumed under the rubric of ‘globalization’. ‘Global’ tends to be equated with transnational and/or world-wide; hence, it addresses quantitative differences in degree but not (alleged) differences in kind. In order to advance our understanding of contemporary politics, ‘global’ needs to be taken seriously. This means, firstly, to understand and to conceptualize ‘global’ as a social category; and, secondly, to uncover ‘global’ as a ‘naturalized’ concept in the Political and International Studies strand of the globalization discourse in order to rescue it for innovative new approaches in the investigation of contemporary politics. In order to do so, the paper suggests adopting a strong linguistic approach starting with the analysis of the word ‘global’. Based on insights from post-structuralism as well as cognitive and general constructivist perspectives it argues that a frame-based corpus linguistic analysis offers the possibility of investigating the collective/social meaning(s) of global in order to operationalize them for the analysis of the ‘global dimension’ of contemporary politics.

La concepció clàssica de la monarquia egípcia a partir de la documentació literària del Regne Mitjà i la seva pervivència en Època Grecorromana. El cas paradigmàtic d'Alexandre el Gran

Aquest estudi s’insereix en un projecte de tesi. L’estudi versa sobre l’ideal egipci de monarquia durant el Regne Mitjà, a partir de l’anàlisi directa de quatre fonts literàries del període. S’ha constatat que la concepció de monarquia resultant, concebuda com a clàssica o modèlica, és la que es transmet en essència fins a l’etapa final de la història antiga egípcia, encara que readaptant-se a les noves realitats polítiques i culturals. L’anàlisi d’aquest ideal teòric de monarquia ha estat fonamental per afrontar l’objectiu essencial del projecte de tesi: l’estudi de la legitimació d’Alexandre el Gran com a faraó d’Egipte, és a dir, l’examen en profunditat del conjunt de mecanismes mitjançant els quals el macedoni va assumir el rol clàssic dels monarques egipcis i que expliciten el procés segons el qual un nou sobirà, que a més era d’origen estranger, fou inserit en la ideologia faraònica tradicional. Per tal de determinar com això es va produir, es fa necessari l’estudi del període en què Alexandre és el titular del tron del país (332-323 aC), és a dir, del moment de gènesi, formulació i desenvolupament de l’entramat ideològic que proporcionarà base teològica al nou govern i l’adequarà a la tradició. Per a l’examen d’aquest període cronològic, la documentació egípcia s’erigeix com la principal font d’informació, i per tant, durant el projecte s’ha compilat i analitzat el conjunt de la documentació de procedència egípcia disponible fins al moment que, datada o no, s’adscriu cronològicament a aquest període.

The spatial inequality of wage income in Barcelona Metropolitan Area

ABSTRACT The measure and estimation of income levels in Barcelona Metropolitan Area (BMA) goes back a long way. Using different approaches and focusing on different municipalities, there is a lot of work in the field. The majority of the literature has focused on the estimation of income levels using variables related to consumption. The empirical evidence on wage differentials has shown an important growth during 80’s and 90’s especially in United Kingdom and USA. Less is known on spatial distribution of inequality. This paper presents a new data set for analyzing spatial distribution of wage income. This data is obtained by matching Wage Structure Survey (WSS) with data from Census disaggregated by census tracts. In this way we have a unique data set with wage incomes for every census track for 36 municipalities belonging to BMA. We develop a descriptive analysis of spatial distribution, testing for spatial autocorrelation and use the family of Generalised Entropy Indices to measure inequality. Properties of the index allow us to decompose inequality into inter and intra-municipality measures. Since we have two cross-sectional data for WSS (1995-2002) we can also analyze the evolution of the inequality in this period of economic growth. Key words: spatial distribution of wages, spatial autocorrelation, inequality indices.

Consum de productes de les màquines de vending i hàbits alimentaris entre els estudiants de la Universitat de Vic

Introducció: Entre els comportaments alimentaris que poden contribuir a una ingesta dietètica inadequada hi ha el consum d’aliments de conveniència, aliments que es caracteritzen per ser d’elevat contingut calòric, riquesa en greixos saturats i sucres. Les màquines de vending són un dels principals exemples de disponibilitat d’aliments de conveniència. Objectius: Avaluar entre els estudiants de la Universitat de Vic (UVic) els hàbits de consum de productes de les màquines de vending i estudiar les característiques generals dels seus hàbits alimentaris. Materials i mètodes: Enquesta realitzada a 253 estudiants de la UVic durant el curs 07/08. Resultats: Un 72.7% dels enquestats consumeixen productes de les Màquines Expenedores d’Aliments i Begudes (MEAB), fonamentalment com a complement dels àpats i un 63.8% dels enquestats refereix que els agradaria rebre informació nutricional sobre els productes ofertats. Els hàbits alimentaris dels estudiants són bastant adequats ja que un 81.4% realitza almenys 4 àpats diaris. La qualitat de l’esmorzar és bona en el 12.3% dels casos i entre aquells que prenen algun aliment a mig matí la qualitat total de l’esmorzar millora (55.7% bona qualitat). Segons el Kidmed un 39.9% realitzen una dieta mediterrània i s’observen diferències segons la qualitat total de l’esmorzar (p&0.001). Conclusions: El consum de productes de les MEAB en l’entorn universitari és molt important, per la qual cosa la millora del perfil nutricional i la implantació d’estratègies informatives sobre els productes, permetrà que els consumidors estiguin més informats i puguin fer una elecció alimentària més saludable. Els hàbits alimentaris de la població d’estudi reflexen que la qualitat de la dieta dels universitaris és bastant bona, tot i que diferents factors podrien millorar-se. Paraules clau: màquines expenedores d’aliments i begudes (MEAB), hàbits alimentaris, universitaris.

Booms, Recessions and Financial Turmoil: A Fresh Look at Investment Decisions under Cyclical Uncertainty

The paper studies the interaction between cyclical uncertainty and investment in a stochastic real option framework where demand shifts stochastically between three different states, each with different rates of drift and volatility. In our setting the shifts are governed by a three-state Markov switching model with constant transition probabilities. The magnitude of the link between cyclical uncertainty and investment is quantified using simulations of the model. The chief implication of the model is that recessions and financial turmoil are important catalysts for waiting. In other words, our model shows that macroeconomic risk acts as an important deterrent to investments.

Object recognition for autonomous objects: comparison of two approaches

Report for the scientific sojourn at the Swiss Federal Institute of Technology Zurich, Switzerland, between September and December 2007. In order to make robots useful assistants for our everyday life, the ability to learn and recognize objects is of essential importance. However, object recognition in real scenes is one of the most challenging problems in computer vision, as it is necessary to deal with difficulties. Furthermore, in mobile robotics a new challenge is added to the list: computational complexity. In a dynamic world, information about the objects in the scene can become obsolete before it is ready to be used if the detection algorithm is not fast enough. Two recent object recognition techniques have achieved notable results: the constellation approach proposed by Lowe and the bag of words approach proposed by Nistér and Stewénius. The Lowe constellation approach is the one currently being used in the robot localization project of the COGNIRON project. This report is divided in two main sections. The first section is devoted to briefly review the currently used object recognition system, the Lowe approach, and bring to light the drawbacks found for object recognition in the context of indoor mobile robot navigation. Additionally the proposed improvements for the algorithm are described. In the second section the alternative bag of words method is reviewed, as well as several experiments conducted to evaluate its performance with our own object databases. Furthermore, some modifications to the original algorithm to make it suitable for object detection in unsegmented images are proposed.

The S. pombe cdc16 gene is required both for maintenance of p34cdc2 kinase activity and regulation of septum formation: a link between mitosis and cytokinesis?

In the fission yeast Schizosaccharomyces pombe, septum formation and cytokinesis are dependent upon the initiation, though not the completion of mitosis. A number of cell cycle mutants which show phenotypes consistent with a defect in the regulation of septum formation have been isolated. A mutation in the S. pombe cdc16 gene leads to the formation of multiple septa without cytokinesis, suggesting that the normal mechanisms that limit the cell to the formation of a single septum in each cycle do not operate. Mutations in the S. pombe early septation mutants cdc7, cdc11, cdc14 and cdc15 lead to the formation of elongated, multinucleate cells, as a result of S phase and mitosis continuing in the absence of cytokinesis. This suggests that in these cells, the normal mechanisms which initiate cytokinesis are defective and that they are unable to respond to this by preventing further nuclear cycles. Genetic analysis has implied that the products of some of these genes may interact with that of the cdc16 gene. To understand how the processes of septation and cytokinesis are regulated and coordinated with mitosis we are studying the early septation mutants and cdc16. In this paper, we present the cloning and analysis of the cdc16 gene. Deletion of the gene shows that it is essential for cell proliferation: spores lacking a functional cdc16 gene germinate, complete mitosis and form multiple septa without undergoing cell cleavage.(ABSTRACT TRUNCATED AT 250 WORDS)

Revealed cardinal preference

I prove that as long as we allow the marginal utility for money (lambda) to vary between purchases (similarly to the budget) then the quasi-linear and the ordinal budget-constrained models rationalize the same data. However, we know that lambda is approximately constant. I provide a simple constructive proof for the necessary and sufficient condition for the constant lambda rationalization, which I argue should replace the Generalized Axiom of Revealed Preference in empirical studies of consumer behavior. 'Go Cardinals!' It is the minimal requirement of any scientifi c theory that it is consistent with the data it is trying to explain. In the case of (Hicksian) consumer theory it was revealed preference -introduced by Samuelson (1938,1948) - that provided an empirical test to satisfy this need. At that time most of economic reasoning was done in terms of a competitive general equilibrium, a concept abstract enough so that it can be built on the ordinal preferences over baskets of goods - even if the extremely specialized ones of Arrow and Debreu. However, starting in the sixties, economics has moved beyond the 'invisible hand' explanation of how -even competitive- markets operate. A seemingly unavoidable step of this 'revolution' was that ever since, most economic research has been carried out in a partial equilibrium context. Now, the partial equilibrium approach does not mean that the rest of the markets are ignored, rather that they are held constant. In other words, there is a special commodity -call it money - that reflects the trade-offs of moving purchasing power across markets. As a result, the basic building block of consumer behavior in partial equilibrium is no longer the consumer's preferences over goods, rather her valuation of them, in terms of money. This new paradigm necessitates a new theory of revealed preference.

Accurate performance of a rat model of schizophrenia in the water maze depends on visual cue availability and stability: a distortion in cognitive mapping abilities?

Rats were treated postnatally (PND 5-16) with BSO (l-buthionine-(S,R)-sulfoximine) in an animal model of schizophrenia based on transient glutathione deficit. The BSO treated rats were impaired in patrolling a maze or a homing table when adult, yet demonstrated preserved escape learning, place discrimination and reversal in a water maze task [37]. In the present work, BSO rats' performance in the water maze was assessed in conditions controlling for the available visual cues. First, in a completely curtained environment with two salient controlled cues, BSO rats showed little accuracy compared to control rats. Secondly, pre-trained BSO rats were impaired in reaching the familiar spatial position when curtains partially occluded different portions of the room environment in successive sessions. The apparently preserved place learning in a classical water maze task thus appears to require the stability and the richness of visual landmarks from the surrounding environment. In other words, the accuracy of BSO rats in place and reversal learning is impaired in a minimal cue condition or when the visual panorama changes between trials. However, if the panorama remains rich and stable between trials, BSO rats are equally efficient in reaching a familiar position or in learning a new one. This suggests that the BSO accurate performance in the water maze does not satisfy all the criteria for a cognitive map based navigation on the integration of polymodal cues. It supports the general hypothesis of a binding deficit in BSO rats.

El problema de una sensibilización del campo de la moralidad en la filosofia trascendental de Kant

La problemática de la investigación se plantea en el contexto de la filosofía trascendental de Kant, en relación al modo en que es en general posible para nosotros representarnos el ámbito de la moralidad. Nuestra comprensión natural o preteórica del funcionamiento del lenguaje parece llevarnos a entender el significado de nuestras palabras en términos de la relación que se establece entre el signo lingüístico y el objeto: nuestros términos lingüísticos están en el lugar del objeto extralingüístico a que refieren y que constituye su significado. A nuestro modo de ver, la afirmación kantiana relativa a que todo nuestro conocimiento comienza con la experiencia, es decir, con aquello que procede de los sentidos, parece estar apuntando a esta intuición fundamental. Ahora bien, la cuestión que cabe plantearse es: de acuerdo con este modelo de significación, ¿cuál es el significado de nuestros términos morales? Si, con Kant, aceptamos que el concepto de deber moral exige el cumplimiento (u omisión) incondicionado de una acción y que, precisamente por las exigencias de universalidad y necesidad que le son inherentes, tal concepto es inderivable de la experiencia, cabe preguntarse cuál es el significado del concepto de deber en sentido moral (y, en general, de los términos morales) y de qué manera somos capaces de representárnoslo. Mi investigación ha pretendido esclarecer precisamente en qué sentido debe entenderse la afirmación kantiana de que en la reflexión sobre la corrección moral de nuestras acciones, para representarnos las exigencias de universalidad y necesidad que son propias del concepto de deber moral, nos servimos analógicamente del concepto de naturaleza, así como analizar la plausibilidad de la propuesta kantiana misma.

‘Right Back Where We Started From’: From ‘The Classics’ To Keynes, And Back Again

The purpose of this paper is to highlight the curiously circular course followed by mainstream macroeconomic thinking in recent times. Having broken from classical orthodoxy in the late 1930s via Keynes’s General Theory, over the last three or four decades the mainstream conventional wisdom, regressing rather than progressing, has now come to embrace a conception of the working of the macroeconomy which is again of a classical, essentially pre-Keynesian, character. At the core of the analysis presented in the typical contemporary macro textbook is the (neo)classical model of the labour market, which represents employment as determined (given conditions of productivity) by the terms of labour supply. While it is allowed that changes in aggregate demand may temporarily affect output and employment, the contention is that in due course employment will automatically return to its ‘natural’ (full employment) level. Unemployment is therefore identified as a merely frictional or voluntary phenomenon: involuntary unemployment - in other words persisting demand-deficient unemployment - is entirely absent from the picture. Variations in aggregate demand are understood to have a lasting impact only on the price level, not on output and employment. This in effect amounts to a return to a Pigouvian conception such as targeted by Keynes in the General Theory. We take the view that this reversion to ideas which should by now be obsolete reflects not the discovery of logical or empirical deficiencies in the Keynes analysis, but results rather from doctrinaire blindness and failure of scholarship on account of which essential features of the Keynes theory have been overlooked or misrepresented. There is an urgent need for a critical appraisal of the current conventional macroeconomic wisdom.

Migration and trade: Theory with an Application to the Eastern- Western European Integration

The remarkable increase in trade flows and in migratory flows of highly educated people are two important features of globalization of the last decades. This paper extends a two-country model of inter- and intraindustry trade to a rich environment featuring technological differences, skill differences and the possibility of international labor mobility. The model is used to explain the patterns of trade and migration as countries remove barriers to trade and to labor mobility. We parameterize the model to match the features of the Western and Eastern European members of the EU and analyze first the effects of the trade liberalization which occured between 1989 and 2004, and then the gains and losses from migration which are expected to occur if legal barriers to labor mobility are substantially reduced. The lower barriers to migration would result in significant migration of skilled workers from Eastern European countries. Interestingly, this would not only benefit the migrants and most Western European workers but, via trade, it would also benefit the workers remaining in Eastern Europe. Key Words: Skilled Migration, Gains from Variety, Real Wages, Eastern-Western Europe. JEL Codes: F12, F22, J61.

Dead-End Jobs or Career Opportunities? Advancement opportunities in call centers

Employment in call centers has grown significantly throughout the world over the past 15 years. In debates about the quality of these new jobs, there are few studies that specifically address promotion opportunities. Using a survey of over 2400 call centers in 16 countries, this paper documents levels and analyzes factors shaping promotions in call centers, and discusses implications for promotions in the service sector generally. On average, less than 10% of call center agents are promoted in any year--5.7% promoted internally to the call center, and 4% promoted elsewhere in the business. Firms that have more complex labor processes and require agents to have higher levels of firm-specific knowledge tend to also have greater promotion opportunities, which might be expected. There are also unexpected findings, including that increased autonomy in the workplace often provides a ‘substitute' to advancement opportunities, and that unionization is associated with fewer advancement opportunities within call centers, though more advancement opportunities to other parts of the business. Key words: promotions, service industries, call centers.
