PERCEPÇÃO DE FATORES E SITUAÇÕES DE RISCO EM MOTORISTAS INFRATORES

O presente estudo teve como objetivo verificar a percepção de situações de acidentes de trânsito por motoristas infratores; levantar dados sócio-demográficos, fatores de riscos e fatores de proteção de motoristas infratores, como também verificou a percepção de invulnerabilidade destes motoristas infratores. A coleta de dados foi realizada através da aplicação de Escala de Percepção de Invulnerabilidade, questionário sócio-demográfico que visou caracterizar o condutor, e entrevista semi-estruturada com finalidade de conhecer as ações do condutor ao volante. A amostra foi realizada por acessibilidade. Foi adotado como critério de inclusão na amostra motoristas habilitados que acumularam mais de vinte pontos em seu prontuário da Carteira de habilitação. O estudo teve um total de 427 sujeitos, sendo 325 do gênero masculino e 102 do gênero feminino. As infrações mais cometidas foram as gravíssimas para os sujeitos habilitados entre 6 e 15 anos, independente do gênero. Em relação à Escala de Invulnerabilidade, identificou-se que a autopercepção positiva foi superior ao senso de proteção e a crença na invulnerabilidade dos sujeitos. Os sujeitos entrevistados têm em média 38 pontos no prontuário, mas consideram-se motoristas cautelosos, atentos, cuidadosos, preocupados com os outros e que procuram obedecer às leis. Verificou-se que o risco está associado com a idéia de perigo, causar danos a outras pessoas ou comprometer sua segurança. As situações de risco estão associadas ao volume excessivo de veículos, alta velocidade, não obediência às leis de trânsito, veículos mal conservados e falta de sinalização. A percepção de riscos tem muito mais a ver com a singularidade do indivíduo diante de algum evento do que com uma estimativa correta de probabilidades. Constatou-se que os níveis elevados de ameaça sempre apresentam estratégias cognitivas de minimização do risco e do seu impacto. Constatou-se que as infrações de trânsito que ocorrem têm a ver com o contexto social. Investigar sobre as possíveis variáveis psicológicas nesse contexto também é uma tarefa de grande amplitude. Os estudos realizados nessa área da psicologia de trânsito no Brasil podem dar mais um passo em direção à compreensão da complexa rede de relações envolvendo o homem, o trânsito e o ambiente.(AU)

The evolution of begging: Signaling and sibling competition

In many species, young solicit food from their parents, which respond by feeding them. Because of the difference in genetic make-up between parents and their offspring and the consequent conflict, this interaction is often studied as a paradigm for the evolution of communication. Existent theoretical models demonstrate that chick signaling and parent responding can be stable if solicitation is a costly signal. The marginal cost of producing stronger signals allows the system to converge to an equilibrium: young beg with intensity that reflects their need, and parents use this information to maximize their own inclusive fitness. However, we show that there is another equilibrium where chicks do not beg and parents’ provisioning effort is optimal with respect to the statistically probable distribution of chicks’ states. Expected fitness for parents and offspring at the nonsignaling equilibrium is higher than at the signaling equilibrium. Because nonsignaling is stable and it is likely to be the ancestral condition, we would like to know how natural systems evolved from nonsignaling to signaling. We suggest that begging may have evolved through direct sibling fighting before the establishment of a parental response, that is, that nonsignaling squabbling leads to signaling. In multiple-offspring broods, young following a condition-dependent strategy in the contest for resources provide information about their condition. Parents can use this information even though it is not an adaptation for communication, and evolution will lead the system to the signaling equilibrium. This interpretation implies that signaling evolved in multiple-offspring broods, but given that signaling is evolutionarily stable, it would also be favored in species which secondarily evolved single-chick broods.

Electrical investigation of p-type 4H-SiC heavily doped by ion implantation

In the last decades, an increasing interest in the research field of wide bandgap semiconductors was observed, mostly due to the progressive approaching of silicon-based devices to their theoretical limits. 4H-SiC is an example among these, and is a mature compound for applications. The main advantages offered 4H-SiC in comparison with silicon are an higher breakdown field, an higher thermal conductivity, a higher operating temperature, very high hardness and melting point, biocompatibility, but also low switching losses in high frequencies applications and lower on-resistances in unipolar devices. Then, 4H-SiC power devices offer great performance improvement; moreover, they can work in hostile environments where silicon power devices cannot function. Ion implantation technology is a key process in the fabrication of almost all kinds of SiC devices, owing to the advantage of a spatially selective doping. This work is dedicated to the electrical investigation of several differently-processed 4H-SiC ion- implanted samples, mainly through Hall effect and space charge spectroscopy experiments. It was also developed the automatic control (Labview) of several experiments. In the work, the effectiveness of high temperature post-implant thermal treatments (up to 2000°C) were studied and compared considering: (i) different methods, (ii) different temperatures and (iii) different duration of the annealing process. Preliminary p + /n and Schottky junctions were also investigated as simple test devices. 1) Heavy doping by ion implantation of single off-axis 4H-SiC layers The electrical investigation is one of the most important characterization of ion-implanted samples, which must be submitted to mandatory post-implant thermal treatment in order to both (i) recover the lattice after ion bombardment, and (ii) address the implanted impurities into lattice sites so that they can effectively act as dopants. Electrical investigation can give fundamental information on the efficiency of the electrical impurity activation. To understand the results of the research it should be noted that: (a) To realize good ohmic contacts it is necessary to obtain spatially defined highly doped regions, which must have conductivity as low as possible. (b) It has been shown that the electrical activation efficiency and the electrical conductivity increase with the annealing temperature increasing. (c) To maximize the layer conductivity, temperatures around 1700°C are generally used and implantation density high till to 10 21 cm -3 . In this work, an original approach, different from (c), is explored by the using very high annealing temperature, around 2000°C, on samples of Al + -implant concentration of the order of 10 20 cm -3 . Several Al + -implanted 4H-SiC samples, resulting of p-type conductivity, were investigated, with a nominal density varying in the range of about 1-5∙10 20 cm -3 and subjected to two different high temperature thermal treatments. One annealing method uses a radiofrequency heated furnace till to 1950°C (Conventional Annealing, CA), the other exploits a microwave field, providing a fast heating rate up to 2000°C (Micro-Wave Annealing, MWA). In this contest, mainly ion implanted p-type samples were investigated, both off-axis and on-axis <0001> semi-insulating 4H-SiC. Concerning p-type off-axis samples, a high electrical activation of implanted Al (50-70%) and a compensation ratio below 10% were estimated. In the work, the main sample processing parameters have been varied, as the implant temperature, CA annealing duration, and heating/cooling rates, and the best values assessed. MWA method leads to higher hole density and lower mobility than CA in equivalent ion implanted layers, resulting in lower resistivity, probably related to the 50°C higher annealing temperature. An optimal duration of the CA treatment was estimated in about 12-13 minutes. A RT resistivity on the lowest reported in literature for this kind of samples, has been obtained. 2) Low resistivity data: variable range hopping Notwithstanding the heavy p-type doping levels, the carrier density remained less than the critical one required for a semiconductor to metal transition. However, the high carrier densities obtained was enough to trigger a low temperature impurity band (IB) conduction. In the heaviest doped samples, such a conduction mechanism persists till to RT, without significantly prejudice the mobility values. This feature can have an interesting technological fall, because it guarantee a nearly temperature- independent carrier density, it being not affected by freeze-out effects. The usual transport mechanism occurring in the IB conduction is the nearest neighbor hopping: such a regime is effectively consistent with the resistivity temperature behavior of the lowest doped samples. In the heavier doped samples, however, a trend of the resistivity data compatible with a variable range hopping (VRH) conduction has been pointed out, here highlighted for the first time in p-type 4H-SiC. Even more: in the heaviest doped samples, and in particular, in those annealed by MWA, the temperature dependence of the resistivity data is consistent with a reduced dimensionality (2D) of the VRH conduction. In these samples, TEM investigation pointed out faulted dislocation loops in the basal plane, whose average spacing along the c-axis is comparable with the optimal length of the hops in the VRH transport. This result suggested the assignment of such a peculiar behavior to a kind of spatial confinement into a plane of the carrier hops. 3) Test device the p + -n junction In the last part of the work, the electrical properties of 4H-SiC diodes were also studied. In this case, a heavy Al + ion implantation was realized on n-type epilayers, according to the technological process applied for final devices. Good rectification properties was shown from these preliminary devices in their current-voltage characteristics. Admittance spectroscopy and deep level transient spectroscopy measurements showed the presence of electrically active defects other than the dopants ones, induced in the active region of the diodes by ion implantation. A critical comparison with the literature of these defects was performed. Preliminary to such an investigation, it was assessed the experimental set up for the admittance spectroscopy and current-voltage investigation and the automatic control of these measurements.

Communicating strategically in the face of terrorism: The Spanish government’s response to the 2004 Madrid bombing attacks

With the re-emergence of insurgency tied to terrorism, governments need to strategically manage their communications. This paper analyzes the effect of the Spanish government’s messaging in the face of the Madrid bombing of March 11, 2004: unlike what happened with the 9/11 bombings in the USA and the 7/07 London attacks, the Spanish media did not support the government’s framing of the events. Taking framing as a strategic action in a discursive form (Pan & Kosicki, 2003), and in the context of the attribution theory of responsibilities, this research uses the “cascading activation” model (Entman, 2003, 2004) to explore how a framing contest was generated in the press. Analysis of the coverage shows that the intended government frame triggered a battle among the different major newspapers, leading editorials to shift their frame over the four days prior to the national elections. This research analyzes strategic contests in framing processes and contributes insight into the interactions among the different sides (government, parties, media, and citizens) to help bring about an understanding of the rebuttal effect of the government’s intended frame. It also helps to develop an understanding of the role of the media and the influence of citizens’ frames on media content.

Ciudad de Vacaciones 1933. El concurso internacional para Playa de San Juan (Alicante)

En 1933, por iniciativa municipal y con el apoyo del Gobierno, con la intención de captar un turismo extranjero y nacional de élite generando una nueva ‘industria’, se convoca el concurso de anteproyectos para la construcción de una ciudad satélite (a modo de ciudad jardín) para destinarla a ciudad de vacaciones en la Playa de San Juan (cvPSJ), Alicante, al que se presentan tres propuestas. Aquí se estudia el anteproyecto ganador (de P. Muguruza), que resulta pionero por las técnicas urbanísticas empleadas (información y zonificación), por la aplicación de la fotografía para la inserción de arquitecturas y equipamientos y por la sensibilidad desplegada en la protección del patrimonio cultural (medioambiental e histórico). Los referentes para este macro complejo turístico (de casi 10 km2), coetáneo a la Ciutat del Repós i Vacances (CRV) de Castelldefels, no proceden tanto de Europa como de EUA. Se realiza un análisis pormenorizado de la ordenación urbanística en atención a cómo el territorio existente la condiciona y se entrelaza con estrategias de promoción turística, donde se combinan la tríada: hotel, deporte y naturaleza (alojamiento, ocio y salud). Pero toda la ciudad está enfocada a un turismo burgués, para el que se prevé una arquitectura comercial que pronto envejecería en su repertorio. Veinticinco años después, en 1958, cuando las condiciones económicas y sociales fueron favorables al desarrollo de la zona, el mundo sería ya otro y el proyecto quedó obsoleto.

Los planos del concurso para la ciudad de vacaciones Playa de San Juan en 1933

En 1933 se celebra el concurso de anteproyectos para la primera ciudad turística de España. Las bases de la convocatoria exigían una extensa documentación: planes, planos y perspectivas. El análisis de la propuesta vencedora —muy sensible a las preexistencias— pone de relieve la secuencia que liga la geografía con la ordenación urbana gracias al pensamiento y a las herramientas gráficas. Primero, se dibuja el territorio levantando acta del mismo recurriendo a los diagramas. Segundo, los datos y las vocaciones del suelo se transforman en una trama urbana zonificada en el espacio y programada en el tiempo. Y tercero, la fotografía del paisaje sugiere los enclaves panorámicos y algunas de las arquitecturas clave. En este hito de la planificación se dan cita las modernas técnicas gráficas y fotográficas que interactúan con el urbanismo moderno del zoning.

Olga Elena Mattei frente al canon de la poesía colombiana de su tiempo (1962-2005)

Ce mémoire vise à placer le travail de la poète colombienne Olga Elena Mattei au sein de la poésie colombienne de son temps (1962-2005). Dans le premier chapitre, certains concepts théoriques sont définis et le terme «canon», axé sur la poésie, est synthétisé. Dans le deuxième chapitre, le paysage de la poésie colombienne de la seconde moitié du XXe siècle est défini. La stylistique des poètes les plus importants et jugés comme étant canoniques, est présentée. Dans le dernier chapitre, les particularités de la poésie de Mattei sont analysées. Il est conclu qu'Olga Elena Mattei fait partie du canon de la poésie colombienne, mais que son travail a contesté le canon dominant de celle-ci, au fil des décennies, et qu'il a été en avance sur les tendances qui émergeraient plus tard. À titre d'exemple, il est montré comment, dans les années soixante du XXe siècle, quand, en Colombie, la rime et le mètre étaient toujours hégémoniques dans la poésie, Olga Elena Mattei a osé écrire et publier en vers libres. Puis, dans les années soixante-dix, lorsque le vers libre a été accepté et il régnait à la poésie colombienne, Mattei fut la première femme à écrire anti-poésie en espagnol. Dans les années quatre-vingt, alors que l'anti-poésie était la principale tendance en Colombie, Mattei s'est consacrée à écrire de la poésie au sujet de la science, jamais réalisée auparavant en Colombie. Et, dans les années quatre-vingt-dix, lorsque le vers libre est dominant en Colombie, Mattei retourne à la rime.

The Kyrgyzstani Presidential Elections: Atambaev’s Challenges. EUCAM Commentary No. 21, November 2011

After much anticipation and anxiety about the presidential elections in Kyrgyzstan, there is a feeling of relief that Almazbek Atambaev won the contest with an overwhelming majority, making a second round of elections unnecessary. The presidential race passed off without violence and unrest, which many in Kyrgyzstan consider an achievement in itself. The scale of Atambaev’s majority took many commentators by surprise as some had predicted a low turnout and a strong oppositional challenge. But according to the Central Electoral Commission, the turnout was 61.28 percent and Atambaev gained 63 percent of the votes. The elections were observed by 792 international observers from 56 countries. Although international observers have criticized electoral irregularities, pointing to incomplete voter registrations and ballot stuffing, overall the elections were assessed as encouraging.

Do Too Many Chefs Really Spoil the Broth? The European Commission, Bureaucratic Politics and European Integration, CES Germany & Europe Working Papers, No. 09.2, 5 August 1999

There is a puzzling, little-remarked contradiction in scholarly views of the European Commission. On the one hand, the Commission is seen as the maestro of European integration, gently but persistently guiding both governments and firms toward Brussels. On the other hand, the Commission is portrayed as a headless bunch of bickering fiefdoms who can hardly be bothered by anything but their own in­ ternecine turf wars. The reason these very different views of the same institution have so seldom come into conflict is quite apparent: EU studies has a set of relatively autonomous and poorly integrated sub­ fields that work at different levels of analysis. Those scholars holding the "heroic" view of the Com­ mission are generally focused on the contest between national and supranational levels that character­ ized the 1992 program and subsequent major steps toward European integration. By contrast, those scholars with the "bureaucratic politics" view are generally authors of case studies or legislative his­ tories of individual EU directives or decisions. However, the fact that these twO images of the Commis­ sion are often two ships passing in the night hardly implies that there is no dispute. Clearly both views cannot be right; but then, how can we explain the significant support each enjoys from the empirical record? The CommiSSion, perhaps the single most important supranational body in the world, certainly deserves better than the schizophrenic interpretation the EU studies community has given it. In this paper, I aim to make a contribution toward the unraveling of this paradox. In brief, the argument I make is as follows: the European Commission can be effective in pursuit of its broad integration goals in spite of, and even because of, its internal divisions. The folk wisdom that too many chefs spoil the broth may often be true, but it need not always be so. The paper is organized as follows. 1 begin with an elaboration of the theoretical position briefly out­ lined above. 1 then tum to a case study from the major Commission efforts to restructure the computer industry in the context of its 1992 program. The computer sector does not merely provide interesting, random illustrations of the hypothesis 1 have advanced. Rather, as Wayne Sandholtz and John Zysman have stressed, the Commission's efforts on informatics formed one of the most crucial parts of the en­ tire 1992 program, and so the Commission's success in "Europeanizing" these issues had significant ripple effects across the entire European political economy. I conclude with some thoughts on the fol­ lowing question: now that the Commission has succeeded in bringing the world to its doorstep, does its bureaucratic division still serve a useful purpose?

Androgen responsiveness to competition in humans: the role of cognitive variables

Although androgens are commonly seen as male sex hormones, it has been established over the years that in both sexes, androgens also respond to social challenges. To explain the socially driven changes in androgens, two theoretical models have been proposed: the biosocial model and the challenge hypothesis. These models are typically seen as partly overlapping; however, they generate different predictions that are clarified here. In humans, sports competition and nonmetabolic competitive tasks have been used in the laboratory setting, as a proxy for agonistic interactions in animals. The results reviewed here show that the testosterone (T) response to competition in humans is highly variable – the studies present postcompetition T levels and changes in T that depend on the contest outcome and that cannot be predicted by the current theoretical models. These conflicting results bring to the foreground the importance of considering cognitive factors that could moderate the androgen response to competition. Among these variables, we elect cognitive appraisal and its components as a key candidate modulating factor. It is known that T also modulates the cognitive processes that are relevant to performance in competition. In this article, we reviewed the evidence arising from studies investigating the effect of administering exogenous T and compare those results with the findings from studies that measured endogenous T levels. Finally, we summarized the importance of also considering the interaction between androgens and other hormones, such as cortisol, when investigating the social modulation of T, as proposed by the dual-hormone hypothesis.
