Survey Methodologies

Social science surveys are undergoing rapidchange due to fundamental shifts in the way data is generated, collected and processed. In order to address this challenge, several large scale social surveys have been integrated into the European Strategic Forum for Research Infrastructures (ESFRI). This has allowed them to develop specialized and professionalized survey work flows within an integrated infrastructural context. This allows for greater sustainability through investment in survey methodologies and data collection which advance the field of social science. This paper examines three case studies within the ESFRI framework; The Survey of Health & Retirement (SHARE) and the European Social Survey (ESS) are European Research Infrastructure Consortia and are both landmarks within the ESFRI landscape. The third case study is of the Generations & Gender Programme which is an Emerging Community in the ESFRI landscape. The three case studies are used to illustrate the developments but also the persistent challenges for social surveys as they evolve with the framework of European Research Infrastructures. Each survey infrastructure is presented and it’s scientific, financial and governance sustainability. Conclusions are drawn as to the sustainability of survey infrastructures and how they could be further improved.

The Welfare State

With some notable exceptions, comparative research on the welfare state falls generally into one of two categories: qualitative and generally descriptive case studies and large-scale quantitative efforts at explanation. Case studies have progressed past the point of being essentially journalistic descriptions of the peculiarities of the policy development process or the policies of a particular society. It is nevertheless true that there has been little progress in moving beyond the case study approach towards building a theory about how and why societies make particular decisions about the priorities and organization of their social welfare efforts. On the other hand, while large-scale aggregate analysis yields theoretical statements about the character of ‘the welfare state’, those conclusions are often so general as to be ‘difficult to relate to… how particular substantive problems have been [and might be] handled.’

Gauss Hermite Quadrature

Abstract This paper develops theoretical foundations for extending Gauss–Hermite quadrature to robust design with computer experiments. When the proposed method is applied with m noise variables, the method requires 4m + 1 function evaluations. For situations in which the polynomial response is separable, this paper proves that the method gives exact transmitted variance if the response is a fourth-order separable polynomial response. It is also proven that the relative error mean and variance of the method decrease with the dimensionality m if the response is separable. To further assess the proposed method, a probability model based on the effect hierarchy principle is used to generate sets of polynomial response functions. For typical populations of problems, it is shown that the proposed method has less than 5% error in 90% of cases. Simulations of five engineering systems were developed and, given parametric alternatives within each case study, a total of 12 case studies were conducted. A comparison is made between the cumulative density function for the hierarchical probability models and a corresponding distribution function for case studies. The data from the case-based evaluations are generally consistent with the results from the model-based evaluation.

Theoretical Foundations

With the topic of Smart Grids taking up momentum, challenges to integrate systems from various vendors’ at large scale in a critical infrastructure have arisen. This issue is usually tackled utilizing standards and, therefore, agreements between the various parties. However, the aspect of the interoperability between systems is not only defined by physical connections, but has a multi-faceted dimension which needs to be dealt with at all layers in order for a semantic and cost-efficient integration. Within this contribution, we motivate the need for a procedural way to deal with interoperability in Smart Grids, show the theoretical foundations and the approach taken and present case studies that cover the problem in scope. Based on these case studies, results are critically reflected and conclusions are drawn.

Detection Of Deception

This work explores the role of multimodal cues in detection of deception in a virtual world, an online community of World of Warcraft players. Case studies from a five-year ethnography are presented in three categories: small-scale deception in text, deception by avoidance, and large-scale deception in game-external modes. Each case study is analyzed in terms of how the affordances of the medium enabled or hampered deception as well as how the members of the community ultimately detected the deception. The ramifications of deception on the community are discussed, as well as the need for researchers to have a deep community knowledge when attempting to understand the role of deception in a complex society. Finally, recommendations are given for assessment of behavior in virtual worlds and the unique considerations that investigators must give to the rules and procedures of online communities.

Abstract The present article provides a detailed description of the corpus of Early Modern Multiloquent Authors (EMMA), as well as two small case studies that illustrate its benefits. As a large-scale specialized corpus, EMMA tries to strike the right balance between big data and sociolinguistic coverage. It comprises the writings of 50 carefully selected authors across five generations, mostly taken from the 17th-century London society. EMMA enables the study of language as both a social and cognitive phenomenon and allows us to explore the interaction between the individual and aggregate levels. The first part of the article is a detailed description of EMMA’s first release as well as the sociolinguistic and methodological principles that underlie its design and compilation. We cover the conceptual decisions and practical implementations at various stages of the compilation process: from text-markup, encoding and data preprocessing to metadata enrichment and verification. In the second part, we present two small case studies to illustrate how rich contextualization can guide the interpretation of quantitative corpus-linguistic findings. The first case study compares the past tense formation of strong verbs in writers without access to higher education to that of writers with an extensive training in Latin. The second case study relates s/th-variation in the language of a single writer, Margaret Cavendish, to major shifts in her personal life.

Digital Newspaper

Purpose The Texas Digital Newspaper Program (TDNP) supports newspaper preservation and access for any title in Texas, from any date, any location and representing any community. As an active member of the Texas Press Association, TDNP also supports large-scale preservation of born-digital newspaper PDF issues for member publishers. This paper aims to explore how the early days of TDNP built a strong foundation of collaboration and support for large-scale preservation projects, including support for preserving a state press association PDF newspaper collection. Design/methodology/approach This paper is a case study of a collaborative endeavor to create a large-scale, statewide digital newspaper preservation hub in Texas. This paper details how individual partnerships led to new and larger partnerships. Figures and tables represent numbers of partner institutions served, numbers of newspapers preserved and screenshots of how these items appear within collections on the digital repository environment of The Portal to Texas History. This paper concludes with recommendations for groups interested in developing their own collaborative projects. Findings As a case study, the data explored include numbers of partnering institutions, materials contributed by partnering institutions and how these numbers help to forward the TDNP agenda. Practical Implications The final recommendations are lessons learned through collaboration, and the implications are real-world advice from the partners developed through the TDNP. Originality/value Hosting over 3.25 million pages of newspapers, the TDNP has become an enormous hub of newspaper preservation in Texas, and it is unique in the numbers of partners it supports and the numbers of pages it is able to host for free access via The Portal to Texas History. This paper is intended to help other groups across the world build their own collaborative preservation efforts, and it offers pragmatic advice derived from hands-on experience.

<p>This paper investigates CSCW aspects of large-scale technical projects based on a case study of a specific Danish engineering company and uncovers challenges to CSCW aplications in this setting. The company is responsible for management and supervision of one of the worlds largest tunnel/bridge construction projects. Our primary aim is to determine requirements on CSCW as they unfold in this concrete setting as opposed to survey and laboratory investigations. The requirements provide feedback to product development both on specific functionality and as a long term vision for CSCW in such settings.</p><p>The initial qualitative analysis identified a number of bottlenecks in daily work, where support for cooperation is needed. Examples of bottlenecks are: sharing materials, issuing tasks, and keeping track of task status. Grounded in the analysis, cooperative design workshops based on scenanos of future work situations were established to investigate the potential of different CSCW technologies in this setting. In the workshops, mock-ups and prototypes were used to support end-users in assessing CSCW technologies based on con crete, hands-on experiences. The workshops uncovered several challenges. First, support for sharing materials would require a huge body of diverse materials to be integrated, for example into a hypermedia network. Second, daily work tasks are event driven and plans change too rapidly for people to register them on a computer. Finally, tasks are closely coupled to materials being processed thus a coordination tool should integrate facilities for managing materials.</p>

Post Disaster

To deal with large-scale disasters, it is necessary to maintain important community functions. One way to achieve this goal is through strategic collaboration with local organizations to ensure district continuity in the aftermath of disaster. It is therefore necessary for local organizations to form a consensus in order to draft measures for the reduction of disaster damage, enabling each organization to act strategically in a post-disaster situation. These measures taken together are called a district continuity plan (DCP).In this paper, the concept of district continuity is defined as a BCP method. The utility of this method is clarified through two case studies. The Kagawa DCP focuses on a possible future Nankai Trough earthquake, and the Basin DCP against large-scale flooding is based on the DCP concept.
