AbstractLSST is a next generation telescope that will produce an unprecedented data flow. The project goal is to deliver data products such as images and catalogs thus enabling scientific analysis for a wide community of users. As a large scale survey, LSST data will be complementary with other facilities in a wide range of scientific domains, including data from ESA or ESO. European countries have invested in LSST since 2007, in the construction of the camera as well as in the computing effort. This latter will be instrumental in designing the next step: how to distribute LSST data to Europe. Astroinformatics challenges for LSST indeed includes not only the analysis of LSST big data, but also the practical efficiency of the data access.

Southern European Countries

Southern European countries are currently experiencing a dramatic economic slump and fully fledged austerity measures. Accordingly, the standard of living of the majority of southern European populaces has fallen significantly. Nevertheless, the dynamics of social contention in the form of strikes and demonstrations that accompany these experiences remain understudied. Why, in certain southern European countries, has collective upset arising from economic deprivation translated into frequent and large-scale contentious acts, while in others it has not? Drawing on the case of Cyprus from a comparative, southern European perspective, we seek to explain how relations within the party system, as well as between parties and civil society, can create the conditions that obstruct open social conflict. The intensity and nature of party-society linkages with causal roots in a country's history can be a sufficient condition for the relative absence of protest.

Gender differences have been observed regarding many political and social issues, yet we lack comprehensive evidence on differences in perceptions on a wide range of security issues increasingly important to voters: military threats, criminality, and terrorism. Previous research suggests that when women are highly politically mobilized, as they are in Sweden, gender differences in political opinion are large. On the other hand, Swedish politicians have worked hard to reduce gender stereotypical thinking. This prompts the question: Are there gender differences in attitudes on security issues in Sweden, and if so, in what ways do the attitudes differ? This study is based on comprehensive data from focus groups and a large-scale survey. The results show that women were more prone to respond with an “ethic of care,” across security issues. Women were more inclined to understand security problems as structural, explained by macho culture, segregation, and injustice. Women tend to support preventive measures that provide individuals with opportunities to choose “the right path,” such as education and economic investment in deprived areas. When asked about national security, women believe more in diplomacy and dialogue. In general, women are less inclined to support various repressive solutions.

Spatial Logics

This article draws upon a large-scale survey of professional (public institution and private company) drone usage in Switzerland. The authors argue that professional drone usage includes a wide range of applications and objectives and, thus, logics of vision and visibility. Instead of being systematic and predictable, the visibilities created by professional drone usage are punctual in occurrence, highly varying in spatial logics and articulations, and, therefore, often unpredictable. This raises important questions and problems with regard to the power dynamics unfolding from the visual and visualising capabilities of the technology that reach far beyond the usual focus on surveillance in current academic engagements with the topic.

AbstractDigital technologies present new methodological and ethical challenges for migration studies: from ensuring data access in ethically viable ways to privacy protection, ensuring autonomy, and security of research participants. This Introductory chapter argues that the growing field of digital migration research requires new modes of caring for (big) data. Besides from methodological and ethical reflexivity such care work implies the establishing of analytically sustainable and viable environments for the respective data sets—from large-scale data sets (“big data”) to ethnographic materials. Further, it is argued that approaching migrants’ digital data “with care” means pursuing a critical approach to the use of big data in migration research where the data is not an unquestionable proxy for social activity but rather a complex construct of which the underlying social practices (and vulnerabilities) need to be fully understood. Finally, it is presented how the contributions of this book offer an in-depth analysis of the most crucial methodological and ethical challenges in digital migration studies and reflect on ways to move this field forward.

Age Of Discovery

The burden of cardiovascular and metabolic diseases worldwide is staggering. The emergence of systems approaches in biology promises new therapies, faster and cheaper diagnostics, and personalized medicine. However, a profound understanding of pathogenic mechanisms at the cellular and molecular levels remains a fundamental requirement for discovery and therapeutics. Animal models of human disease are cornerstones of drug discovery as they allow identification of novel pharmacological targets by linking gene function with pathogenesis. The zebrafish model has been used for decades to study development and pathophysiology. More than ever, the specific strengths of the zebrafish model make it a prime partner in an age of discovery transformed by big-data approaches to genomics and disease. Zebrafish share a largely conserved physiology and anatomy with mammals. They allow a wide range of genetic manipulations, including the latest genome engineering approaches. They can be bred and studied with remarkable speed, enabling a range of large-scale phenotypic screens. Finally, zebrafish demonstrate an impressive regenerative capacity scientists hope to unlock in humans. Here, we provide a comprehensive guide on applications of zebrafish to investigate cardiovascular and metabolic diseases. We delineate advantages and limitations of zebrafish models of human disease and summarize their most significant contributions to understanding disease progression to date.

Open-ended questions have routinely been included in large-scale survey and panel studies, yet there is some perplexity about how to actually incorporate the answers to such questions into quantitative social science research. Tools developed recently in the domain of natural language processing offer a wide range of options for the automated analysis of such textual data, but their implementation has lagged behind. In this study, we demonstrate straightforward procedures that can be applied to process and analyze textual data for the purposes of quantitative social science research. Using more than 35,000 textual answers to the question “What else are you worried about?” from participants of the German Socio-economic Panel Study (SOEP), we (1) analyzed characteristics of respondents that determined whether they answered the open-ended question, (2) used the textual data to detect relevant topics that were reported by the respondents, and (3) linked the features of the respondents to the worries they reported in their textual data. The potential uses as well as the limitations of the automated analysis of textual data are discussed.

And Storage

In the large scale distributive environment involving mobile network, metadata server and storage applications, the data access and the security measures are of paramount importance. In parallel application processing, data is distributed across multiple servers and storage location. Ensuring confidentiality and availability of the data to the authorised users at the appropriate time involves high level of encryption algorithms, key management schemes and security algorithms. In this paper, key escrow scheme is implemented with the light weighted symmetric algorithm, elliptic curve cryptography in the distributed environment. Key escrow centre is established along with the metadata server and the encryption keys are segmented and shared among the multiple sub agents using Shamir threshold sharing scheme. The implementation of Key Escrow mechanism with Elliptical Curve Cryptography provides wide range of flexibility and confidentiality in the distributed environment. It also eliminates private secret sub key problem and thereby ensuring better security.

Abstract This article proposes the term Big Translation History (BTH) to describe a translation history that can be analysed computationally and that we define as involving: (1) large-scale research (geographical and chronological); (2) massive data understood as big data, accompanied by little data, and drawing on a wide range of often heterogeneous and non-structured sources; and (3) the use of computational techniques as part of the research process, and for the production of knowledge, rather than helping only with visualisation of data. We advance the hypothesis that one of the main possibilities of BTH, as a conceptual framework and a methodology, is to help decentralize translation history and literary and cultural history, in a broad sense. The article goes on to present an analysis of the circulation of literary translations and the agents involved in the Spanish-speaking world between 1898 and 1945 as a case study in BTH.
