Sob o rótulo da globalização, as ciências humanas e sociais têm sido forçadas a rever seu pensamento para encontrar novas maneiras de falar sobre as situações de mudança ao nosso redor e para reorientar-se conceitualmente em um aparente ‘mundo sem fronteiras’. Este artigo analisa algumas dessas formas, sugerindo que a pesquisa em currículo transnacional como tarefa, como talvez inclusiva de algo para além dos estudos curriculares como subárea, tem preocupações, pontos de entrada e horizontes de promulgação amplos, inconstantes, imprevisíveis, que levantam uma série de questões e considerações éticas que exigem maior compromisso nos espaços em que as fronteiras percebidas forem transgredidas no ato da investigação. Usando os relatórios sobre os resultados do PISA como disparador intelectual, este artigo discute quatro questões que surgem no ato investigativo em currículo transnacional: a comparação como princípio de produção de conhecimento; as estratégias de agrupamento onto-teo-filosóficas e a delimitação da ética; o retorno do sujeito centrado, humanista, racional e as críticas a esse sujeito inspirado no Iluminismo; as questões relativas à causalidade, ou seja, como os processos de atribuição são forjados e que tipos de ‘legitimação via procedimento’ operam na crítica social. Em vez de sugerir uma nova ordem, este artigo busca um questionamento mais profundo dos repetitivos pressupostos ocidentalistas.

The eighth chapter, written by Gayle Morris, is entitled “Performing pedagogy and the re (construction) of global/local selves.” Morris tackles a unique perspective with regard to globalization and education. A major characteristic of today’s globalized world is the diversity of people living within societies and communities. Classrooms in public schools and universities in the United States, Canada, Australia, and Britain are comprised of students from all parts of the world, a reality which is increasing the challenges faced by teachers and policy makers. Morris particularly discusses second language teaching and learning and the inadequacy of second language educators who are mostly approaching from “White/mainstream” positivist models and approaches to language teaching (p. 137). Morris highlights the “fixing” of immigrants and ethnic minority identity, and how the inefficient training of ESL teachers is affecting the global/ local selves of students. This chapter is invaluable contribution in this volume given the number of immigrants to western countries is on the rise.

When the second of two targets (T2) is presented temporally close to the first target (T1) in rapid serial visual presentation, accuracy to detect/identify T2 is markedly reduced as compared to longer target separations. This is known as the attentional blink (AB), and is thought to reflect a limitation of selective attention. While most individuals show an AB, research has demonstrated that individuals are variously susceptible to this effect. To explain these differences, Dale and Arnell (2010) examined whether dispositional differences in attentional breadth, as measured by the Navon letter task, could predict individual AB magnitude. They found that individuals who showed a natural bias toward the broad, global level of Navon letter stimuli were less susceptible to the AB as compared to individuals who showed a natural bias toward the detailed, local aspects of Navon letter stimuli. This suggests that individuals who naturally broaden their attention can overcome the AB. However, it was unclear how stable these individual differences were over time, and whether a variety of global/local tasks could predict AB performance. As such, the purpose of this dissertation was to investigate, through four empirical studies, the nature of individual differences in both global/local bias and the AB, and how these differences in attentional breadth can modulate AB performance. Study 1 was designed to examine the stability of dispositional global/local biases over time, as well as the relationships among three different global/local processing measures. Study 2 examined the stability of individual differences in the AB, as well as the relationship among two distinct AB tasks. Study 3 examined whether the three distinct global/local tasks used in Study 1 could predict performance on the two AB tasks from Study 2. Finally, Study 4 explored whether individual differences in global/local bias could be manipulated by exposing participants to high/low spatial frequencies and Navon stimuli. In Study 1, I showed that dispositional differences in global/local bias were reliable over a period of at least a week, demonstrating that these individual biases may be trait-like. However, the three tasks that purportedly measure global/local bias were unrelated to each other, suggesting that they measure unique aspects of global/local processing. In Study 2, I found that individual variation in AB performance was also reliable over a period of at least a week, and that the two AB task versions were correlated. Study 3 showed that dispositional global/local biases, as measured by the three tasks from Study 1, predicted AB magnitude, such that individuals who were naturally globally biased had smaller ABs. Finally, in Study 4 I demonstrated that these dispositional global/local biases are resistant to both spatial frequency and Navon letter manipulations, indicating that these differences are robust and intractable. Overall, the results of the four studies in this dissertation help clarify the role of individual differences in attentional breadth in selective attention.

En la Argentina, el año 2002 marca el inicio de una serie de transformaciones productivas con fuerte impacto sobre las dinámicas territoriales, a partir de la llegada de inversiones extranjeras directas. Una importante porción de dichas inversiones se orienta a desarrollar actividades de baja jerarquización, en donde la competitividad se obtiene vía la reducción de los costos laborales y el otorgamiento de ventajas impositivas y subsidios hacia las empresas. La significativa expansión de la actividad de los call centers tercerizadores -que, en los últimos años, se localizan masiva y vertiginosamente en las principales ciudades del interior de nuestro país- es la evidencia empírica de este fenómeno. Analizar sus características, junto con una detallada descripción de las interacciones de los organismos estatales y los sectores políticos, sociales y económicos involucrados en la instalación de los call centers, no solo permite observar las transformaciones territoriales -en tanto se insertan nuevas actividades productivas y de empleo- sino que visibiliza mecanismos de cooperación y/o conflicto mediante los cuales los actores nacionales y foráneos posibilitan y modelan la inserción de lo global en lo local, materializando así novedosas lógicas de organización territorial, que representamos bajo el concepto "nuevas territorialidades". A lo largo de todo el trabajo, intentamos que nuestra mirada de estos procesos pueda dar cuenta de las (a)simetrías de poder entre los agentes económicos y actores estatales y extraestatales, en el marco de espacios locales periféricos en una época de globalización

This article contributes to the theorization of the role of informal regulation (undertaken by leading firms) in the ongoing organization of global production networks. It does so through a qualitative case study of BHP Billiton's Ravensthorpe Nickel Operation (RNO) in the rural Shire of Ravensthorpe in Western Australia. This less tangible, and to date under-researched, dimension of global production networks is foregrounded through a focus on the corporate social responsibility strategy implemented by RNO in the service of achieving and/or demonstrating a broader ‘social licence to operate’. This ‘licence’ functions – beyond the corporation – as a legitimated and legitimating multi-scalar mechanism through which to gain and maintain access to mineral resources and thus to establish viable and ongoing global production networks. Further, this informal regulation is shown to shape social relations and qualities of place conducive to competitive global mineral extraction and to facilitate the positioning of local communities and places in mineral global production networks.

An important question of biological relevance is the polymorphism of the double-helical DNA structure in its free form, and the changes that it undergoes upon protein-binding. We have analysed a database of free DNA crystal structures to assess the inherent variability of the free DNA structure and have compared it with a database of protein-bound DNA crystal structures to ascertain the protein-induced variations.

Sydney playwright Lachlan Philpott’s Bison (2000/2009) is immersed in a sweaty, summery Antipodean scene of bronzed and toned bodies. It is located in the flora and fauna of gum trees and biting ants. Yet, despite this, it could be argued that at its heart it is not a specifically Australian site, but an all-too translatable scene that seems to be played out in gay clubs, bars, chatrooms and saunas around the Western world: men repeating patterns, looking for sex or love; checking out bodies, craving perfection; avoiding, and occasionally seeking, disease. At least, that was my assumption when I decided to direct the play in Belfast, Northern Ireland, in 2009. Philpott came to Belfast to workshop the play with the actors and, as a group, we restructured the play and tried to find a way to ‘de-Australianise’ it without necessarily placing it in a new geographical place - Northern Ireland - through linguistic clues in the text. As Philpott put it: ‘Let’s not make this play about Belfast or Sydney or London or anywhere because it is not a fair reflection of these scenes. Maybe we should just identify the generic elements of this world and then make Bison a play that reflects gaytown – because the rituals are all the same in Western society’. The experience of doing the play in Belfast made clear, however, that ideas of a global gay identity/experience –though highly marketed – fail to account for the vastly different situations of embodied gay experience. And the Northern Irish gay experience, while it has imported the usual ‘generic’ tropes of gayness, sits within a specific cultural context in which the farsighted legislation on equality for gays (imposed by either London or the EU) vastly outstrips wider societal thinking. For many in Northern Ireland, erstwhile MP Iris Robinson’s comments about homosexuality being an ‘abomination’ were a reason to support her, rather than to reject her. For me, the comments were the catalyst to doing Bison in Belfast.

Biodiversity continues to decline in the face of increasing anthropogenic pressures such as habitat destruction, exploitation, pollution and introduction of alien species. Existing global databases of species' threat status or population time series are dominated by charismatic species. The collation of datasets with broad taxonomic and biogeographic extents, and that support computation of a range of biodiversity indicators, is necessary to enable better understanding of historical declines and to project - and avert - future declines. We describe and assess a new database of more than 1.6 million samples from 78 countries representing over 28,000 species, collated from existing spatial comparisons of local-scale biodiversity exposed to different intensities and types of anthropogenic pressures, from terrestrial sites around the world. The database contains measurements taken in 208 (of 814) ecoregions, 13 (of 14) biomes, 25 (of 35) biodiversity hotspots and 16 (of 17) megadiverse countries. The database contains more than 1% of the total number of all species described, and more than 1% of the described species within many taxonomic groups - including flowering plants, gymnosperms, birds, mammals, reptiles, amphibians, beetles, lepidopterans and hymenopterans. The dataset, which is still being added to, is therefore already considerably larger and more representative than those used by previous quantitative models of biodiversity trends and responses. The database is being assembled as part of the PREDICTS project (Projecting Responses of Ecological Diversity In Changing Terrestrial Systems - http://www.predicts.org.uk). We make site-level summary data available alongside this article. The full database will be publicly available in 2015.

Solving systems of nonlinear equations is a very important task since the problems emerge mostly through the mathematical modelling of real problems that arise naturally in many branches of engineering and in the physical sciences. The problem can be naturally reformulated as a global optimization problem. In this paper, we show that a self-adaptive combination of a metaheuristic with a classical local search method is able to converge to some difficult problems that are not solved by Newton-type methods.

The development of effective methods for predicting the quality of three-dimensional (3D) models is fundamentally important for the success of tertiary structure (TS) prediction strategies. Since CASP7, the Quality Assessment (QA) category has existed to gauge the ability of various model quality assessment programs (MQAPs) at predicting the relative quality of individual 3D models. For the CASP8 experiment, automated predictions were submitted in the QA category using two methods from the ModFOLD server-ModFOLD version 1.1 and ModFOLDclust. ModFOLD version 1.1 is a single-model machine learning based method, which was used for automated predictions of global model quality (QMODE1). ModFOLDclust is a simple clustering based method, which was used for automated predictions of both global and local quality (QMODE2). In addition, manual predictions of model quality were made using ModFOLD version 2.0-an experimental method that combines the scores from ModFOLDclust and ModFOLD v1.1. Predictions from the ModFOLDclust method were the most successful of the three in terms of the global model quality, whilst the ModFOLD v1.1 method was comparable in performance to other single-model based methods. In addition, the ModFOLDclust method performed well at predicting the per-residue, or local, model quality scores. Predictions of the per-residue errors in our own 3D models, selected using the ModFOLD v2.0 method, were also the most accurate compared with those from other methods. All of the MQAPs described are publicly accessible via the ModFOLD server at: http://www.reading.ac.uk/bioinf/ModFOLD/. The methods are also freely available to download from: http://www.reading.ac.uk/bioinf/downloads/.
