Over the past 3 decades, the status of sea turtles and the need for their protection to aid population recovery have increasingly captured the interest of government agencies, non-governmental organisations (NGOs) and the general public worldwide. This interest has been matched by increased research attention, focusing on a wide variety of topics relating to sea turtle biology and ecology, together with the interrelations of sea turtles with the physical and natural environments. Although sea turtles have been better studied than most other marine fauna, management actions and their evaluation are often hindered by the lack of data on turtle biology, human–turtle interactions, turtle population status and threats. In an effort to inform effective sea turtle conservation a list of priority research questions was assembled based on the opinions of 35 sea turtle researchers from 13 nations working in fields related to turtle biology and/or conservation. The combined experience of the contributing researchers spanned the globe as well as many relevant disciplines involved in conservation research. An initial list of more than 200 questions gathered from respondents was condensed into 20 metaquestions and classified under 5 categories: reproductive biology, biogeography, population ecology, threats and conservation strategies.

This book confirms that globalisation is reshaping educators’ work and lives towards a more global education. Understanding how teachers make meaning from and respond to travel revealed aspects of knowledge creation and identity formation. Set within contexts of globalisation, the study investigated global education through analysis of changing definitions and meanings by taking an historical stance. Teachers revealed that their study tour created new knowledge, teaching pedagogies and greater awareness of stereotypes both held and disclosed from students. The practices and thinking described by participants were consistent with calls for greater cosmopolitan teaching. A collection of ‘travel’ stories written by the author are included. The book sheds light on how teachers embed global imaginaries in their teaching. This in turn builds understanding around how globalisation is reshaping local contexts and individuals’ thinking and being. The findings challenge global education as a discrete framework and suggest teachers’ experiences as influential on education now in a global world.

The Latrobe Valley region of Victoria, Australia, has the highest rate of asbestos disease in the state due to extensive past use of asbestos in the power industry. Current responses to asbestos disease epidemics in Australia and internationally are dominated by medical, scientific, legal and government perspectives. The voices and perspectives of those most directly affected – exposed and diseased workers, their families and communities – are relatively rarely heard.A qualitative interview study was conducted to determine what people in the Latrobe Valley community think could or should be done following their own asbestos disease epidemic. Analysis identified several themes. Notably, these represent a sophisticated community understanding of issues that is largely consistent with state-of-the-art occupational health and public health knowledge.Some themes are well known already, eg the need for fair and timely compensation, adequate healthcare facilities and services, and more education. Others point to neglected possibilities, such as the need for reconciliation and social healing to complement the dominant individual medico-legal focus. Employer suppression of hazard information and denial of asbestos-related disease in past decades continues to have a profound effect on people's views in the present. Reconciliation in some form, eg acknowledgement of or apology for past wrongs, was identified as a necessary first step in developing new and better policy and practice responses; action in this regard has important implications for the implementation and effectiveness of other policy and practice interventions. Further, a need for substantive community participation in the development of policy and practice responses – currently lacking – was identified. Findings suggest that community is an under-recognised and under-utilised resource in responding to a local asbestos disease epidemic.The Latrobe Valley situation is a microcosm of the broader Australian and international story. It offers insights on the perspectives of those most affected by asbestos issues, how such people and their views can be used to strengthen current policy and practice responses, and how their participation is essential to building comprehensive public and social health responses to this global problem.

In today’s changing economy, moving rapidly beyond industrial and information priorities, the creative arts, industries and enterprises have a powerful capacity for transforming a society’s cultural and economic capabilities and growth. One of the greatest challenges for present and future workplace participants in the context of this rapid change is the need to adapt to changing roles within a capitalism which has moved beyond a focus on the production of commodities to a greater social and economic flexibility. Gee talks of the ‘new capitalism’ requiring ‘shape-shifting portfolio people’ , creative and entrepreneurial individuals who can take on multiple identities. The key to managing this change is to focus on building a capacity to design new identities, affinity groups and networks. The virtual villages project described in this paper is a creative response to building ‘shape-shifting’ skills, focusing on the power of narrative immersion through virtual world environments to explore issues for rural and regional communities. The project aims to assist local communities in geographically diverse regions to develop their capacities for designing new identities through participating in the creation of digital storylines and characters for problem-solving. This will also have the outcome of an expanded affinity group (the project participants and their digital audiences) and potentially global networks (the archipelago). The concept of virtual villages utilizes associational narrative techniques, exploring portals of virtual worlds, thresholds of community discovery and fragments of narrative as the framework. Developing associational narratives which explore and share creative problem solving across diverse virtual villages will provide both individuals and the community with the ‘shape-shifting’ capacity to situate themselves beyond current community networks and identities.

Whether a perceived increase in the abundance of jellyfishes is related to changing marine environments has been considered primarily using large-scale analyses of multi-species assemblages. Yet jellyfish blooms-rapid increases in the biomass of pelagic coelenterate species-are single-species demographic events. Using published and new genetic analyses and population surveys, we investigate whether there may be a critical knowledge gap between the scales of recent analyses and the scales of natural phenomena. We find that scyphomedusae may show population genetic structure over scales of tens to hundreds of kilometers, that environments vary regionally and locally, and that populations of medusae can display uncorrelated dynamics on these scales. These findings suggest genetic differences between populations and/or environmental differences between sites are important determinants of population dynamics in these jellyfishes. Moreover, the local abundance of medusae may be most strongly correlated with preceding rather than current local environmental conditions, indicating there is a cumulative time-course to the formation of 'blooms'. Broad-scale macro-ecological analyses will need to build from coordinated, long-term, fine-grained studies to synthesize, rather than mask, population-level phenomena in larger-scale analyses. © 2014 Springer International Publishing Switzerland.

Biomedical time series clustering that automatically groups a collection of time series according to their internal similarity is of importance for medical record management and inspection such as bio-signals archiving and retrieval. In this paper, a novel framework that automatically groups a set of unlabelled multichannel biomedical time series according to their internal structural similarity is proposed. Specifically, we treat a multichannel biomedical time series as a document and extract local segments from the time series as words. We extend a topic model, i.e., the Hierarchical probabilistic Latent Semantic Analysis (H-pLSA), which was originally developed for visual motion analysis to cluster a set of unlabelled multichannel time series. The H-pLSA models each channel of the multichannel time series using a local pLSA in the first layer. The topics learned in the local pLSA are then fed to a global pLSA in the second layer to discover the categories of multichannel time series. Experiments on a dataset extracted from multichannel Electrocardiography (ECG) signals demonstrate that the proposed method performs better than previous state-of-the-art approaches and is relatively robust to the variations of parameters including length of local segments and dictionary size. Although the experimental evaluation used the multichannel ECG signals in a biometric scenario, the proposed algorithm is a universal framework for multichannel biomedical time series clustering according to their structural similarity, which has many applications in biomedical time series management.

When novelist Charmian Clift returned to Australia in 1964 after 14 years in England and Greece, she was commissioned to write a women’s column in the Sydney Morning Herald and Melbourne Herald. Her topics ranged widely, from food and drink, migrants and hospitality, famine and peace, children and religion, pop music and Aborigines to travel and housewives. By all accounts Clift struck a chord with her readers, her feel for connecting the vagaries of everyday life with historical and global events and social shifts made hers a distinctive voice in the daily press. This article explores the cosmopolitan outlook of Clift’s newspaper column: a world of hospitality and travel based on a common humanity, a perspective that neither feared nor favoured class, caste and colour, all the while not shying away from criticisms of the moral ambiguities of a sophisticated worldliness. It argues that Clift’s cosmopolitan perspective offered women a moral space that circumscribed local conditions. The article adds to an emerging body of knowledge on the gendered dimensions of cosmopolitanism and seeks to understand what kind of cosmopolitan world for women existed in 1960s

Migratory and resident hosts have been hypothesized to fulfil distinct roles in infectious disease dynamics. However, the contribution of resident and migratory hosts to wildlife infectious disease epidemiology, including that of low pathogenic avian influenza virus (LPAIV) in wild birds, has largely remained unstudied. During an autumn H3 LPAIV epizootic in free-living mallards (Anas platyrhynchos) - a partially migratory species - we identified resident and migratory host populations using stable hydrogen isotope analysis of flight feathers. We investigated the role of migratory and resident hosts separately in the introduction and maintenance of H3 LPAIV during the epizootic. To test this we analysed (i) H3 virus kinship, (ii) temporal patterns in H3 virus prevalence and shedding and (iii) H3-specific antibody prevalence in relation to host migratory strategy. We demonstrate that the H3 LPAIV strain causing the epizootic most likely originated from a single introduction, followed by local clonal expansion. The H3 LPAIV strain was genetically unrelated to H3 LPAIV detected both before and after the epizootic at the study site. During the LPAIV epizootic, migratory mallards were more often infected with H3 LPAIV than residents. Low titres of H3-specific antibodies were detected in only a few residents and migrants. Our results suggest that in this LPAIV epizootic, a single H3 virus was present in resident mallards prior to arrival of migratory mallards followed by a period of virus amplification, importantly associated with the influx of migratory mallards. Thus migrants are suggested to act as local amplifiers rather than the often suggested role as vectors importing novel strains from afar. Our study exemplifies that a multifaceted interdisciplinary approach offers promising opportunities to elucidate the role of migratory and resident hosts in infectious disease dynamics in wildlife.

In order to influence global policy effectively, conservation scientists need to be able to provide robust predictions of the impact of alternative policies on biodiversity and measure progress towards goals using reliable indicators. We present a framework for using biodiversity indicators predictively to inform policy choices at a global level. The approach is illustrated with two case studies in which we project forwards the impacts of feasible policies on trends in biodiversity and in relevant indicators. The policies are based on targets agreed at the Convention on Biological Diversity (CBD) meeting in Nagoya in October 2010. The first case study compares protected area policies for African mammals, assessed using the Red List Index; the second example uses the Living Planet Index to assess the impact of a complete halt, versus a reduction, in bottom trawling. In the protected areas example, we find that the indicator can aid in decision-making because it is able to differentiate between the impacts of the different policies. In the bottom trawling example, the indicator exhibits some counter-intuitive behaviour, due to over-representation of some taxonomic and functional groups in the indicator, and contrasting impacts of the policies on different groups caused by trophic interactions. Our results support the need for further research on how to use predictive models and indicators to credibly track trends and inform policy. To be useful and relevant, scientists must make testable predictions about the impact of global policy on biodiversity to ensure that targets such as those set at Nagoya catalyse effective and measurable change.

Application of optimization algorithm to PDE modeling groundwater remediation can greatly reduce remediation cost. However, groundwater remediation analysis requires a computational expensive simulation, therefore, effective parallel optimization could potentially greatly reduce computational expense. The optimization algorithm used in this research is Parallel Stochastic radial basis function. This is designed for global optimization of computationally expensive functions with multiple local optima and it does not require derivatives. In each iteration of the algorithm, an RBF is updated based on all the evaluated points in order to approximate expensive function. Then the new RBF surface is used to generate the next set of points, which will be distributed to multiple processors for evaluation. The criteria of selection of next function evaluation points are estimated function value and distance from all the points known. Algorithms created for serial computing are not necessarily efficient in parallel so Parallel Stochastic RBF is different algorithm from its serial ancestor. The application for two Groundwater Superfund Remediation sites, Umatilla Chemical Depot, and Former Blaine Naval Ammunition Depot. In the study, the formulation adopted treats pumping rates as decision variables in order to remove plume of contaminated groundwater. Groundwater flow and contamination transport is simulated with MODFLOW-MT3DMS. For both problems, computation takes a large amount of CPU time, especially for Blaine problem, which requires nearly fifty minutes for a simulation for a single set of decision variables. Thus, efficient algorithm and powerful computing resource are essential in both cases. The results are discussed in terms of parallel computing metrics i.e. speedup and efficiency. We find that with use of up to 24 parallel processors, the results of the parallel Stochastic RBF algorithm are excellent with speed up efficiencies close to or exceeding 100%.

Compreender o comportamento de compra das organizações é um importante desafio, tanto para os meios acadêmicos quanto empresariais, não apenas pela abrangência e complexidade do tema, mas também pelos volumes de negócios envolvidos entre empresas. Com o intuito de contribuir com o aprofundamento dos conhecimentos atinentes ao assunto, o presente estudo objetivou descrever as variáveis organizacionais referentes ao comportamento de compra das grandes empresas industriais associadas à Federação das Indústrias do Estado do Rio Grande do Sul. Foram pesquisadas 82 organizações com mais de 500 funcionários e analisados seus comportamentos relativos à compra de itens considerados "A" de estoque e utilizados diretamente em seus processos produtivos. Buscou-se verificar a utilização da tecnologia como forma de otimização de processos, o nível de prúfissionalização dos funcionários dos departamentos, a fonnalização e centralização empregadas nas atividades de compras, as principais políticas, regras e procedimentos da área, a participação da mesma em decisões consideradas de alto nível relativas a fontes de suprimentos e a predominância de atividades estratégicas ou operacionais no funcionamento dos setores de compras. Visou-se também identificar a existência de associações entre tais aspectos e o tamanho das empresas. Verificou-se que as empresas preocupam-se com o investimento em recursos para os setores de compras, através do oferecimento de treinamentos a seus funcionários e da disponibilização de tecnologias para a otimização de rotinas. Constatou-se também que as organizações são, em geral, bastante formalizadas e centralizadas, e que o comprador dispõe de pouca autonomia. Com relação às políticas relativas a fontes de fornecimento, observou-se que a maioria das empresas pratica a terceirização de seus processos produtivos e possui relacionamentos mais estreitos com seus fornecedores, sem entretanto, limitar-se a uma base local de suprimento, pois reconhecem e adquirem insumos de acordo com as alternativas globais. Identificou-se ainda a prevalência de atividades operacionais em relação às estratégicas no funcionamento dos setores de aquisição pesquisados. Com relação ao tamanho das organizações, foi possível constatar que as maiores tendem a oferecer mais treinamentos a seus profissionais de compras, possuem mais recursos tecnológicos alocados a estes setores, mais comumente estabelecem relacionamentos de longo prazo com os fornecedores e importam componentes.

This paper addresses topics - either relevant or confusing or needing more attention - related to measuring the trade and poverty nexus. It sheds a critical light on the existing material and suggests needed research lines. It starts with questions akin to the LAC realities; then, keeping this view, general methodological issues are also examined. In a broader perspective, further ideas for the research agenda are formulated. The main conclusion is that relevant findings still demand considerable efforts. Moreover, the Information-measurement-model-evaluation paradigm is not enough, policy guidelines being usually too general. In LAC, it must be extended and deepened, accounting more for the heterogeneity of cases, including, whenever possible, the physical constraints and incorporating new ways of integrating both the local and global perspectives. Other aspects, like the role of specific juridical measures, should play a role. How all this can be combined into more encompassing evaluations remains open

The major purpose of this thesis is to verify, from a Brazilian perspective, how global and contextual issues influence the management learning in Multinationals. The management learning derived from the interaction of holding and sidiaries/colligates of Multinational corporation is supposed to be subject to convergent and divergent forces, the former related to global and standardized organizational practices, and the latter, is seen as a social practice subject to cultural and organizational singularities. A model was constructed to relate the dichotomy between the universality of the management practices and technologies and the particularity of the contexts where they operate, to the dichotomy between the singularities in organization and national level. This model is composed of the international, global, managerial and inter-organizational dimensions related, respectively, to the cultural and political diversity; to the universal forces of practices and values; to the managerial capabilities and resources in the organization, consolidated as best practices and to the interaction between holding and subsidiaries and the resulted learning. The combined result of these dimensions influences the knowledge flow and the learning derived from it. The field research was constituted of five cases of internationalized Brazilian firms, with a solid experience in their management systems. The main subjects of this study were executives and ofessionals/managers who respond to the management development. The data were first collected in the headquarters and complemented with visits to subsidiaries/joint ventures in other countries, in loco or with expatriated people who return to Brazil. The central supposition was validated. So, the management learning ¿ is driven by the global capitalism practices and by the global culture where they are immersed, reproducing a hegemonic vision and a common language (global dimension); ¿ incorporates the more propagated and dominant managerial values, although there are some variations when they are applied in the subsidiaries/joint ventures; is the product of the assimilation of international recognized and planned managerial practices, with the acculturation power, although not completely; is the result mainly of the managerial practice in work; is impacted not only by cross-cultural and managerial factors, but also by the business environment of the firm; is given according to the capabilities and resources in the organization, guiding the form of assimilation of practices and technologies, with global application or not (managerial dimension); ¿ is affected by the cross-cultural diversity involving the countries of the holding and the subsidiaries/joint ventures where the firm is and is given as a reproduction of the political context of the holding and subsidiaries countries (international dimension); ¿ faces aligned concurrent institutional pressures between corporate or global systems, practices of other subsidiaries/joint ventures and local practices; is more difficult to reach when there is not permeability between organizational cultures and identities of a Multinational firm; is affected by how much the relationship process across these unities is self-referenced; is facilitated by the construction and improvement of the knowledge network (interorganizational dimension). Finally some contributions of this study are exposed, including extensions of the proposed model and suggestions, recommendations for future research.

The objective of this dissertation is to explore and deeply study the concepts about Glocal Marketing, explaining this recent phenomenon, highlighting the importance and the influence of local culture on the marketing mix of global organizations, in order to have successful commercialization of their products and services in different markets. Searching for a better understanding of Glocal Marketing became extremely important in the XXI Century, since there is an increase in the number of global companies which want to explore new markets in order to survive and remain in the highly competitive market. Concepts of Globalization, Marketing, Glocal Marketing, Culture are defined and explored. Also, the influence of culture on consumer behavior and on the marketing mix of global organizations is analyzed. The Hofstede¿s cultural typology is explained and it is used to give the reader an overview and a better understanding about the cultural influence in the acceptance of new products in new markets. The relationship between culture and marketing mix is discussed, as well as the importance of standardization versus customization of the marketing mix among countries with high cultural differences. The methodology is composed by descriptive research and a case study about a global organization, the Coca-Cola Company. Therefore, this dissertation aims to show and exemplify how the Coca-Cola Company applies glocal strategies on its marketing mix as a way to establish a competitive advantage in the market.
