Inversiones extraterritoriales, crisis ambiental y acción colectiva en América Latina

Un creciente número de actores extraterritoriales del sector privado, a menudo en asociación con el estado, están expandiendo las fronteras de economías extractivas y de exportaciones primarias a nuevos territorios rurales en América Latina. Este artículo analiza las condiciones que podrían impulsar esfuerzos significativos para abordar problemas ambientales en territorios dominados por actividades extensas, controladas externamente y basadas en recursos naturales. Se estudian tres casos: la acuicultura del salmón en Chiloé (Chile), la fruticultura en O’Higgins (Chile) y la producción de gas en Tarija (Bolivia). Concluimos que es poco probable que dichos esfuerzos ocurran, a menos que los problemas ambientales amenacen directamente la viabilidad a corto plazo de las actividades o emerjan movimientos sociales para exigir cambios.

ENABLE: a wrist worn device with integrated accessible services to support old people living independently and safely at home

This RTD project, 2007-2009, is partly funded by the European Commission, in Framework Programme 6. It aims to assist elderly people for living well, independently and at case. ENABLE will provide a number of services for elderly people based on the new technology provided by mobile phones. The project is developing a Wrist unit with both integrated and external sensors, and with a radio frequency link to a mobile phone. Dedicated ENABLE software running on the wrist unit and mobile phone makes these services fully accessible for the elderly users. This paper outlines the fundamental motivation and the approach which currently is undertaken in order to collect the more detailed user needs and requirements. The general architecture and the design of the ENABLE system are outlined.

Emotioner och värdegrundsarbete : Om lärare, fostran och elever i en mångkulturell skola

This thesis explores aspects of teachers’ obligation to implement and discuss what are referred to in the Swedish national school curricula as “fundamental values” (“värdegrunden” in Swedish). The aim is to describe and analyze dilemmas in interpretations of and teachers’ work with these fundamental values. Four questions are related to this aim. The first addresses difficulties discussed in conversations between seven upper secondary teachers, during nine meetings over the course of one year. In these conversations the teachers reflected upon how to interpret the fundamental values in relation to their daily practice. The second question focuses on the considerable diversity of Swedish schools and examines the work of the teachers through a perspective of intersectionality. The third question concerns how Martha Nussbaum’s theory of emotions as judgments of value could be used for an understanding of the identified dilemmas. The fourth question focuses on ways in which the participating teachers’ discussions may contribute to a wider discussion about possible aims and circumstances of teachers’ work with the fundamental values. Chapter 2 introduces the theoretical framework of the study, Martha Nussbaum’s (2001) ethical thinking on emotions as judgments of value. She argues that emotions have four common cognitive components. They have (1) external objects, and are directed towards these objects. They are (2) intentional, reflecting a person’s particular point of view, his or her special way of beholding the object, and (3) consist of judgments, i.e. views of how things in the world are. According to Nussbaum’s Aristotelian ethics, emotions also (4) mirror the individual’s vision of what a good human life is like, and the vulnerability of it. The concept of eudaimonia, a fulfilled or flourishing life, is central. Chapter 3 focuses on ideas of ethnicity, and on the specific obligation mentioned in the curriculum of counteracting xenophobia and intolerance in a multicultural society. Chapter 4 discusses various aspects of the teachers’ thoughts on religiosity within Swedish society (often depicted as one of most secular in the world) and within the educational system that is non-denominational. Chapter 5 draws attention to different ways in which the teachers view and teach pupils about sexual orientation. Chapter 6 presents conclusions on potential advantages of and challenges involved in Nussbaum’s Aristotelian theory of emotions, when applied to teachers’ views of and practical work with the fundamental values described in the curriculum. One advantage is that emotions may be intellectually scrutinized and morally assessed, on grounds that are known beforehand and discussed in a democratic process. The non-productive division between emotions, on the one hand, and intellectual and moral capabilities, on the other, is transcended by Nussbaum’s theory. An important challenge is to reflect upon when to discuss the cognitive content of pupils’ emotions, and when it is appropriate to state what is right or wrong, and try to influence pupils accordingly. Keywords: Emotions, vulnerability, values education, religious education, teaching, Martha Nussbaum, ethnicity, religion, sexual orientation.

Rawls and Health Care

John Rawls’s A Theory of Justice (1971), his first major work articulating his theory of justice as fairness, was immediately recognized as a fundamental contribution to political philosophy in the twentieth century. Working within the tradition established by previous philosophers such as Kant and Locke, Rawls employed the contract theory approach. Taking it to a higher order of abstraction, he sought to determine not what the structure of social organization would be, but what the principles which governed social institutions would be under a hypothetical contracting situation. Rawls uses this contract theory approach to construct a society in which the morally irrelevant contingencies of nature and social arrangements are mitigated by principles of justice which govern the basic institutions of society. A common observation has been that Rawls left out any discussion of health care and how it might fit into his conception of a just society. Several philosophers have articulated expansions of the theory to account for health care. In the chapters that follow I will continue this tradition and consider how justice as fairness might be expanded to account for just health care allocation. In doing so, I hope to answer a particularly strong critique of the theory brought up by Amartya Sen and Martha Nussbaum, and to argue for a broadened conception of health care which takes into account the complex causal relationship between society and human health.

Uma avaliação do acesso à qualidade de vida dos moradores dos bairros Rubem Berta e Moinhos de Vento, em Porto Alegre/RS

De acordo com o Censo Demográfico do Instituto Brasileiro de Geografia e Estatística (IBGE), realizado no ano de 2000 (PMPA, 2004a, 2004b), existem grandes disparidades socioeconômicas entre os bairros Rubem Berta e Moinhos de Vento, em Porto Alegre/RS. Como exemplo, o rendimento médio mensal dos responsáveis pelo domicílio nos bairros referidos, captados em 2000, foi de 29,33 salários mínimos no bairro Moinhos de Vento e de 4,05 salários mínimos no bairro Rubem Berta. Inicialmente, elege-se o quesito renda para, então, partir-se em busca de dimensões mais abrangentes em termos de qualidade de vida. Objetiva-se verificar o acesso à qualidade de vida dos habitantes dos bairros Rubem Berta e Moinhos de Vento realizando-se um estudo comparativo entre os dois bairros pesquisados, por meio da Abordagem da Capacitação e, mais especificamente, das capacitações centrais de Martha Nussbaum (2000), como também sob a impressão dos próprios sujeitos estudados. Discute-se também a possibilidade do enfoque da capacitação contribuir para a elaboração e avaliação de programas sociais. Uma pesquisa de campo caracteriza o tipo de estudo. O método de investigação é a análise interpretativa, fundamentada em entrevistas baseadas nas dez capacitações centrais de Nussbaum (2000), bem como nos métodos comparativo e observacional casual. As entrevistas foram realizadas junto a membros das associações de moradores dos bairros Rubem Berta (Associação Comunitária de Moradores do Conjunto Residencial Rubem Berta - AMORB) e Moinhos de Vento (Moinhos Vive). Como resultados, a pesquisa apresenta alguns elementos que levam a crer que seis blocos temáticos (dos dez abordados) sintetizam as maiores preocupações dos moradores do bairro Rubem Berta (saúde; violência; nutrição e habitação; planejamento familiar; educação, cultura e diversão; e meio ambiente), e que dois blocos temáticos (violência e meio-ambiente) constituem as maiores preocupações do bairro Moinhos de Vento.

Is The amphibian tree of life really fatally flawed?

Wiens (2007, Q. Rev. Biol. 82, 55-56) recently published a severe critique of Frost et al.'s (2006, Bull. Am. Mus. Nat. Hist. 297, 1-370) monographic study of amphibian systematics, concluding that it is a disaster and recommending that readers simply ignore this study. Beyond the hyperbole, Wiens raised four general objections that he regarded as fatal flaws: (1) the sampling design was insufficient for the generic changes made and taxonomic changes were made without including all type species; (2) the nuclear gene most commonly used in amphibian phylogenetics, RAG-1, was not included, nor were the morphological characters that had justified the older taxonomy; (3) the analytical method employed is questionable because equally weighted parsimony assumes that all characters are evolving at equal rates; and (4) the results were at times clearly erroneous, as evidenced by the inferred non-monophyly of marsupial frogs. In this paper we respond to these criticisms. In brief: (1) the study of Frost et al. did not exist in a vacuum and we discussed our evidence and evidence previously obtained by others that documented the non-monophyletic taxa that we corrected. Beyond that, we agree that all type species should ideally be included, but inclusion of all potentially relevant type species is not feasible in a study of the magnitude of Frost et al. and we contend that this should not prevent progress in the formulation of phylogenetic hypotheses or their application outside of systematics. (2) Rhodopsin, a gene included by Frost et al. is the nuclear gene that is most commonly used in amphibian systematics, not RAG-1. Regardless, ignoring a study because of the absence of a single locus strikes us as unsound practice. With respect to previously hypothesized morphological synapomorphies, Frost et al. provided a lengthy review of the published evidence for all groups, and this was used to inform taxonomic decisions. We noted that confirming and reconciling all morphological transformation series published among previous studies needed to be done, and we included evidence from the only published data set at that time to explicitly code morphological characters (including a number of traditionally applied synapomorphies from adult morphology) across the bulk of the diversity of amphibians (Haas, 2003, Cladistics 19, 23-90). Moreover, the phylogenetic results of the Frost et al. study were largely consistent with previous morphological and molecular studies and where they differed, this was discussed with reference to the weight of evidence. (3) The claim that equally weighted parsimony assumes that all characters are evolving at equal rates has been shown to be false in both analytical and simulation studies. (4) The claimed strong support for marsupial frog monophyly is questionable. Several studies have also found marsupial frogs to be non-monophyletic. Wiens et al. (2005, Syst. Biol. 54, 719-748) recovered marsupial frogs as monophyletic, but that result was strongly supported only by Bayesian clade confidence values (which are known to overestimate support) and bootstrap support in his parsimony analysis was < 50%. Further, in a more recent parsimony analysis of an expanded data set that included RAG-1 and the three traditional morphological synapomorphies of marsupial frogs, Wiens et al. (2006, Am. Nat. 168, 579-596) also found them to be non-monophyletic.Although we attempted to apply the rule of monophyly to the naming of taxonomic groups, our phylogenetic results are largely consistent with conventional views even if not wth the taxonomy current at the time of our writing. Most of our taxonomic changes addressed examples of non-monophyly that had previously been known or suspected (e.g., the non-monophyly of traditional Hyperoliidae, Microhylidae, Hemiphractinae, Leptodactylidae, Phrynobatrachus, Ranidae, Rana, Bufo; and the placement of Brachycephalus within Eleutherodactylus, and Lineatriton within Pseudoeurycea), and it is troubling that Wiens and others, as evidenced by recent publications, continue to perpetuate recognition of non-monophyletic taxonomic groups that so profoundly misrepresent what is known about amphibian phylogeny.

CMS physics technical design report, volume II: Physics performance

CMS is a general purpose experiment, designed to study the physics of pp collisions at 14 TeV at the Large Hadron Collider ( LHC). It currently involves more than 2000 physicists from more than 150 institutes and 37 countries. The LHC will provide extraordinary opportunities for particle physics based on its unprecedented collision energy and luminosity when it begins operation in 2007. The principal aim of this report is to present the strategy of CMS to explore the rich physics programme offered by the LHC. This volume demonstrates the physics capability of the CMS experiment. The prime goals of CMS are to explore physics at the TeV scale and to study the mechanism of electroweak symmetry breaking - through the discovery of the Higgs particle or otherwise. To carry out this task, CMS must be prepared to search for new particles, such as the Higgs boson or supersymmetric partners of the Standard Model particles, from the start- up of the LHC since new physics at the TeV scale may manifest itself with modest data samples of the order of a few fb(-1) or less. The analysis tools that have been developed are applied to study in great detail and with all the methodology of performing an analysis on CMS data specific benchmark processes upon which to gauge the performance of CMS. These processes cover several Higgs boson decay channels, the production and decay of new particles such as Z' and supersymmetric particles, B-s production and processes in heavy ion collisions. The simulation of these benchmark processes includes subtle effects such as possible detector miscalibration and misalignment. Besides these benchmark processes, the physics reach of CMS is studied for a large number of signatures arising in the Standard Model and also in theories beyond the Standard Model for integrated luminosities ranging from 1 fb(-1) to 30 fb(-1). The Standard Model processes include QCD, B-physics, diffraction, detailed studies of the top quark properties, and electroweak physics topics such as the W and Z(0) boson properties. The production and decay of the Higgs particle is studied for many observable decays, and the precision with which the Higgs boson properties can be derived is determined. About ten different supersymmetry benchmark points are analysed using full simulation. The CMS discovery reach is evaluated in the SUSY parameter space covering a large variety of decay signatures. Furthermore, the discovery reach for a plethora of alternative models for new physics is explored, notably extra dimensions, new vector boson high mass states, little Higgs models, technicolour and others. Methods to discriminate between models have been investigated. This report is organized as follows. Chapter 1, the Introduction, describes the context of this document. Chapters 2-6 describe examples of full analyses, with photons, electrons, muons, jets, missing E-T, B-mesons and tau's, and for quarkonia in heavy ion collisions. Chapters 7-15 describe the physics reach for Standard Model processes, Higgs discovery and searches for new physics beyond the Standard Model.

The CMS experiment at the CERN LHC

The Compact Muon Solenoid (CMS) detector is described. The detector operates at the Large Hadron Collider (LHC) at CERN. It was conceived to study proton-proton (and lead-lead) collisions at a centre-of-mass energy of 14 TeV (5.5 TeV nucleon-nucleon) and at luminosities up to 10(34)cm(-2)s(-1) (10(27)cm(-2)s(-1)). At the core of the CMS detector sits a high-magnetic-field and large-bore superconducting solenoid surrounding an all-silicon pixel and strip tracker, a lead-tungstate scintillating-crystals electromagnetic calorimeter, and a brass-scintillator sampling hadron calorimeter. The iron yoke of the flux-return is instrumented with four stations of muon detectors covering most of the 4 pi solid angle. Forward sampling calorimeters extend the pseudo-rapidity coverage to high values (vertical bar eta vertical bar <= 5) assuring very good hermeticity. The overall dimensions of the CMS detector are a length of 21.6 m, a diameter of 14.6 m and a total weight of 12500 t.

The amphibian tree of life

The evidentiary basis of the currently accepted classification of living amphibians is discussed and shown not to warrant the degree of authority conferred on it by use and tradition. A new taxonomy of living amphibians is proposed to correct the deficiencies of the old one. This new taxonomy is based on the largest phylogenetic analysis of living Amphibia so far accomplished. We combined the comparative anatomical character evidence of Haas (2003) with DNA sequences from the mitochondrial transcription unit HI (12S and 16S ribosomal RNA and tRNA(Valine) genes, 2,400 bp of mitochondrial sequences) and the nuclear genes histone H3, rhodopsin, tyrosinase, and seven in absentia, and the large ribosomal subunit 28S (approximate to 2,300 bp of nuclear sequences; ca. 1.8 million base pairs; x ($) over bar = 3.7 kb/terminal). The dataset includes 532 terminals sampled from 522 species representative of the global diversity of amphibians as well as seven of the closest living relatives of amphibians for outgroup comparisons.
