The Social contract with endogenous sentiments

Moral values infuence individual behavior and social interactions. A specially signif- cant instance is the case of moral values concerning work e¤ort. Individuals determine what they take to be proper behaviour and judge the others, and themselves, accordingly. They increase their esteem -and self-esteem- for those who perform in excess of the standard and decrease their esteem for those who work less. These changes in self-esteem result from the self-regulatory emotions of guilt or pride extensively studied in Social Psychology. We examine the interactions between sentiments, individual behaviour and the social contract in a model of rational voting over redistribution where individual self-esteem and relative es-teem for others are endogenously determined. Individuals di¤er in their productivities. The desired extent of redistribution depends both on individual income and on individual attitudes toward others. We characterize the politico-economic equilibria in which sentiments, labor supply and redistribution are simultaneously determined. The model has two types of equilibria. In "cohesive" equilibria, all individuals conform to the standard of proper behav- iour, income inequality is low and social esteem is not biased toward any particular type. Under these conditions equilibrium redistribution increases in response to larger inequality. In a "clustered" equilibrium skilled workers work above the mean while unskilled workers work below. In such an equilibrium, income inequality is large and sentiments are biased in favor of the industrious. As inequality increases, this bias may eventually overtake the egoistic demand for greater taxation and equilibrium redistribution decreases. The type of equilibrium that emerges crucially depends on inequality. We contrast the predictions of the model with data on inequality, redistribution, work values and attitudes toward work and toward the poor for a set of OECD countries.

Estudi de comportaments socials amb eixams de robots reconfigurables

Els eixams de robots distribuïts representen tot un món de possibilitats al camp de la microrobòtica, però existeixen pocs estudis que n'analitzin els comportaments socials i les interaccions entre robots autònoms distribuïts. Aquests comportaments han de permetre assolir de la manera més efectiva possible un bon resultat. Prenent com a base l'objectiu esmentat, aquest treball detalla diferents polítiques de cerca i de reconfiguració dels robots i estudia els seus comportaments per tal de determinar quins d'ells són més útils per solucionar un problema concret amb les plagues d'erugues i corcs als camps de cigroneres.

L'oficina judicial a Catalunya: mitjà real d'una justícia eficaç pel ciutadà del segle XXI

En aquest estudi es pretenia assolir la pràctica d'un sistema que només s'ha plantejat teòricament, doncs l'experiència acumulada, ja abans de la reforma orgànica de 2003, parteix de la figura dels serveis comuns, amb un criteri d'eficiència, racionalitat i economia per invertir en l'Administració de justícia catalana. Assumir i donar resposta jurídica concreta a tots els reptes tècnics pot fer-se des d'una perspectiva dogmàtica, tot i que el temps transcorregut també permet advertir exigències pràctiques a l'àmbit de la dogmàtica processal, el context socio-cultural i, naturalment, les necessitats laborals. En aquest sentit, els objectius s'introdueixen cap a la garantia d'un apropament material, conceptual i quotidià de l'Administració de justícia al ciutadà, establert com a eix inextricable del sistema, tenint present la de vegades despesa incomprensible en una realitat històricament menystinguda i deficitària, malgrat l'esforç pressupostari fet els darrers anys que, malgrat tot, no ha evitat discordances greus per manca de racionalitat i eficiència en el consum diari dels operadors implicats. Es pretén aconseguir, per mitjà del nou sistema d'oficina judicial estructurat, un avenç efectiu i econòmic a l'estat de la Justícia al país, especialment envers la dilació dels tràmits, a més de reclamar reformes legals, de caire processal especialment, que no es prestin a mers paràmetres d'ajust formal, sinó que incideix substantivament en millores per altre part reclamades fa temps per la doctrina científica. S'han aconseguit les fites definides des del punt de vista teòric, així com s'ha afrontat tots el problemes conceptuals i hipòtesis pràctiques més significatives, establint pautes de resposta sota la prèvia determinació de les qüestions debatudes i els conflictes habituals que correspon enfrontar. D'aquesta manera, s'ha estudiat la normativa en presència i la jurisprudència que hi dona actualitat pràctica, sense oblidar la doctrina d'autors. S'ha repassat el funcionament existent a l'oficina judicial i les previsions de la mateixa en un futur immediat, remarcant les noves tecnologies en ús i projectades, de igual manera que les bondats i crítiques de tots els operador jurídics actuants.

Trajectòries de vida dels estrangers encarcerats

Aquest informe complementa l’estudi Estrangers a les presons catalanes i fa un aprofundiment qualitatiu d’aquell estudi. Recull les particularitats de cadascun dels casos seleccionats i profunditza en l’experiència migratòria de l’estranger, la seva situació familiar i social aquí i al seu país, la seva trajectòria delictiva, la seva experiència penitenciària i les expectatives cara el futur un cop surti de la presó. Totes aquestes aportacions es descriuen però també s’interpreten i es valoren per tal que ajudin a establir nous matisos a tenir en compte per valorar les necessitats d’intervenció amb la població estrangera als centres penitenciaris i les seves perspectives específiques d’inserció social. La principal conclusió d’aquesta part de l’estudi és la identificació dels dos elements clau que permeten definir unes perspectives de futur pessimistes, incertes o optimistes respecte les possibilitats dels estrangers encarcerats un cop surtin de presó. Aquests dos elements clau per pronosticar-ho són: 1) la distància que hi ha entre les expectatives de futur i les possibilitats reals d’assolir-les, i 2) la pròpia voluntat de la persona.

Hominització versus humanització : Cal un nou paradigma?

Treball de recerca amb uns objectius definits per a una possible anàlisi crítica dels estudis sobre hominització que, de manera emblemàtica, representa la figura d'Eudald Carbonell. Es considera més idoni per a jutjar el valor de la seva aportació pel fet de no centrar-se en el camp de la prehistòria, sinó el de la sociologia, la filosofia de la tecnologia i la filosofia de la història.

Avaluació i intervenció psicoeducativa en les relacions materno/paterno-filials en famílies desestructurades

Anàlisi, avaluació i intervenció psicoeducativa en un programa assistencial i de suport a les relacions materno/paternofilials en famílies desestructurades. Els usuaris són els pares i les mares separats o divorciats (i els seus fills menors) amb conflictes entre ells i on ha estat el jutge qui ha establert el règim de visites. Es dóna suport i orientació als progenitors i als menors que acudeixen al centre per a fer l'intercanvi o l'estada del menor amb el progenitor no custodi, per a facilitar i millorar la relació entre les parts (menors, part custòdia i part no-custòdia).

Stare decisis: Rhetoric and substance

Stare decisis allows common law to develop gradually and incrementally. We show howjudge-made law can steadily evolve and tend to increase efficiency even in the absence ofnew information. Judges' opinions must argue that their decisions are consistent withprecedent: this is the more costly, the greater the innovation they are introducing. As aresult, each judge effects a cautious marginal change in the law. Alternative models inwhich precedents are either strictly obeyed or totally discarded would instead predictabrupt large swings in legal rules. Thus we find that the evolution of case law isgrounded not in binary logic fixing judges' constraints, but in costly rhetoric shapingtheir incentives. We apply this finding to an assessment of the role of analogicalreasoning in shaping the joint development of different areas of law.

Insurance and safety after September 11, 2001: Coming to grips with the costs and threats of terrorism

This chapter, originally written as a consequence of the terrorist attacksof September 11, 2001, provides an elementary, everyday introduction tothe concepts of risk and insurance. Conceptually, risk has two dimensions:a potential loss, and the chance of that loss being realized. People can,however, transfer risk to insurance companies against the payment ofso-called premiums. In practice, however, one needs accurate assessmentsof both losses and probabilities to judge whether premiums are appropriate.For many risks, this poses little problem (e.g., life insurance); however,it is difficult to assess risks of many other kinds of events such as actsof terrorism. It is emphasized, that through evolution and learning, peopleare able to handle many of the common risks that they face in life. Butwhen people lack experience (e.g., new technologies, threats of terrorism),risk can only be assessed through imagination. Not surprisingly, insurancecompanies demand high prices when risks are poorly understood. In particular,the cost of insurance against possible acts of terrorism soared afterSeptember 11. How should people approach risk after the events of that day?Clearly, the world needs to protect itself from the acts of terrorists andother disturbed individuals. However, it is also important to address the root causes of such antisocial movements. It is, therefore, suggested thatprograms addressed at combatting ignorance, prejudice, and socialinequalities may be more effective premiums for reducing the risk ofterrosrtism than has been recognized to date.

Factors affecting visual analysis in single-case designs

Visual inspection remains the most frequently applied method for detecting treatment effects in single-case designs. The advantages and limitations of visual inference are here discussed in relation to other procedures for assessing intervention effectiveness. The first part of the paper reviews previous research on visual analysis, paying special attention to the validation of visual analysts" decisions, inter-judge agreement, and false alarm and omission rates. The most relevant factors affecting visual inspection (i.e., effect size, autocorrelation, data variability, and analysts" expertise) are highlighted and incorporated into an empirical simulation study with the aim of providing further evidence about the reliability of visual analysis. Our results concur with previous studies that have reported the relationship between serial dependence and increased Type I rates. Participants with greater experience appeared to be more conservative and used more consistent criteria when assessing graphed data. Nonetheless, the decisions made by both professionals and students did not match sufficiently the simulated data features, and we also found low intra-judge agreement, thus suggesting that visual inspection should be complemented by other methods when assessing treatment effectiveness.

Translation and validation of the Ten-Item-Personality Inventory into spanish and catalan

In response to an increasing need for ever-shorter personality instruments, Gosling, Rentfrow, and Swann (2003) developed the Ten-Item-Personality Inventory (TIPI), which measures the dimensions of the Five Factor Model (FFM) using 10 items (two for each dimension) and can be administered in about one minute. In two studies and using a multi-judge (self and observer) and multi-instrument design, we develop Spanish (Castilian) and Catalan versions of the TIPI and evaluate them in terms of internal consistency, test-retest reliability, convergent, discriminant, and content validity, as well as self-observer correlations. Test-retest correlations were strong, and convergence with the NEO-PI-R factors was significant. There were also strong correlations between observer ratings and the participants’ self-ratings. Despite some inconsistencies with respect to the Agreeableness scale, the Catalan translation and both translations into Spanish of the original TIPI demonstrated sufficient psychometric properties to warrant use as a Five Factor personality measure when the use of longer instruments is not convenient or possible. Furthermore, as the first translation of a brief standard Big Five Instrument into Catalan, this work should facilitate future research on personality in the Catalan-speaking population.

Corruption in building the image of politics in television news broadcasts

This work analyses the political news of eight Spanish television channels in order to see what image is built of politics, and particularly how the news of corruption affects the image of politics in Spanish news broadcasts. Different cases of corruption such as Gürtel, Palma Arena and those associated with judge Baltasar Garzón in his final stage in office, occupy part of the study. A new methodology is therefore proposed that enables the quality of the political information emitted from inside and outside the political content of the news programmes to be observed. Particular attention is paid to the news broadcasts of Televisión Española and Cuatro as those which offer a more balanced view of politics, and channels such as La Sexta, which give priority to a narrative construction of politics in the news programmes around causes of corruption.

The relative salience of facial features when differentiating faces based on an interference paradigm

Research on face recognition and social judgment usually addresses the manipulation of facial features (eyes, nose, mouth, etc.). Using a procedure based on a Stroop-like task, Montepare and Opeyo (J Nonverbal Behav 26(1):43-59, 2002) established a hierarchy of the relative salience of cues based on facial attributes when differentiating faces. Using the same perceptual interference task, we established a hierarchy of facial features. Twenty-three participants (13 men and 10 women) volunteered for the experiment to compare pairs of frontal faces. The participants had to judge if the eyes, nose, mouth and chin in the pair of images were the same or different. The factors manipulated were the target-distractive factor (4 face components 9 3 distractive factors), interference (absent vs. present) and correct answer (the same vs. different). The analysis of reaction times and errors showed that the eyes and mouth were processed before the chin and nose, thus highlighting the critical importance of the eyes and mouth, as shown by previous research.

Citation auctions as a method to improve selection of scientific papers

This paper describes the basis of citation auctions as a new approach to selecting scientific papers for publication. Our main idea is to use an auction for selecting papers for publication through - differently from the state of the art - bids that consist of the number of citations that a scientist expects to receive if the paper is published. Hence, a citation auction is the selection process itself, and no reviewers are involved. The benefits of the proposed approach are two-fold. First, the cost of refereeing will be either totally eliminated or significantly reduced, because the process of citation auction does not need prior understanding of the paper's content to judge the quality of its contribution. Additionally, the method will not prejudge the content of the paper, so it will increase the openness of publications to new ideas. Second, scientists will be much more committed to the quality of their papers, paying close attention to distributing and explaining their papers in detail to maximize the number of citations that the paper receives. Sample analyses of the number of citations collected in papers published in years 1999-2004 for one journal, and in years 2003-2005 for a series of conferences (in a totally different discipline), via Google scholar, are provided. Finally, a simple simulation of an auction is given to outline the behaviour of the citation auction approach

Escala de satisfacción con el tratamiento recibido (CRES-4): la versión en español

The satisfaction of consumers and users with the products and services is an issue that in recent years has been taking more and more importance and now it even reaches psychotherapy. This paper presents the Spanish adaptation of the Consumer Reports Effectiveness Scale (CRES-4)consisting of four items designed to evaluate whether patients are satisfied with the therapy they have received and if it has been perceived as effective or not. Its global score is intended to reflect treatment effectiveness as percived by the patient. Existing studies suggest that the CRES-4 is a good complementary tool to judge, in particular, satisfaction with treatment received.
