Stumbling Blocks in Empirical Legal Research: Case Study Research

This article examines the main assumptions and theoretical underpinnings of case study method in legal studies. It considers the importance of research design, including the crucial roles of the academic literature review, the research question and the use of rival theories to develop hypotheses and the practice of identifying the observable implications of those hypotheses. It considers the selection of data sources and modes of analysis to allow for valid analytical inferences to be drawn in respect of them. In doing so it considers, in brief, the importance of case study selection and variations such as single or multi case approaches. Finally it provides thoughts about the strengths and weaknesses associated with undertaking socio-legal and comparative legal research via a case study method, addressing frequent stumbling blocks encountered by legal researchers, as well as ways to militate them. It is written with those new to the method in mind.

Validating A knowledge transfer framework in health services

The study of knowledge transfer (KT) has been proceeding in parallel but independently in health services and in business, presenting an opportunity for synergy and sharing. This paper uses a survey of 32 empirical KT studies with their 96 uniquely named determinants of KT success to identify ten unique determinants for horizontal knowledge transfer success. These determinants, the outcome measure of Knowledge Use, and separate explicit and tacit transfer flows constitute the KT Framework, extending the work of previous KT framework authors. Our Framework was validated through a case study of the transfer of clinical practice guideline knowledge between the cardiac teams of selected Ontario hospitals, using a survey of senders and receivers developed from the KT literature. The study findings were: 8 of 10 determinants were supported by the Successful Transfer Hospitals; and 4 of 10 determinants were found to a higher degree in the Successful than non-Successful transfer hospitals. Taken together, the results show substantive support for the KT Framework determinants, indicating aggregate support of 9 of these determinants, but not the 10th - Knowledge Complexity. The transfer of tacit knowledge was found to be related to the transfer of the explicit knowledge and expressed as the transfer or recreation of resource profile and internal process tacit knowledge, where this tacit transfer did not require interactions between Sender and Receiver. This study provides managers with the building blocks to assess and improve the success rates of their knowledge transfers.

Secure and Scalable Statistical Computation of Questionnaire Data in R

Collecting data via a questionnaire and analyzing them while preserving respondents’ privacy may increase the number of respondents and the truthfulness of their responses. It may also reduce the systematic differences between respondents and non-respondents. In this paper, we propose a privacy-preserving method for collecting and analyzing survey responses using secure multi-party computation (SMC). The method is secure under the semi-honest adversarial model. The proposed method computes a wide variety of statistics. Total and stratified statistical counts are computed using the secure protocols developed in this paper. Then, additional statistics, such as a contingency table, a chi-square test, an odds ratio, and logistic regression, are computed within the R statistical environment using the statistical counts as building blocks. The method was evaluated on a questionnaire dataset of 3,158 respondents sampled for a medical study and simulated questionnaire datasets of up to 50,000 respondents. The computation time for the statistical analyses linearly scales as the number of respondents increases. The results show that the method is efficient and scalable for practical use. It can also be used for other applications in which categorical data are collected.

Defining the nation, defining public television: discourses of publics on public service television in post-communist Latvia

Institutional and political economy approaches have long dominated the study of post-Communist public broadcasting, as well as the entire body of post-Communist media transformations research, and the enquiry into publics of public broadcasting has traditionally been neglected. Though media scholars like to talk about a deep crisis in the relationship between public broadcasters and their publics in former Communist bloc countries across Central and Eastern Europe, little has been done to understand the relationship between public broadcasters and their publics in these societies drawing on qualitative audience research tradition. Building on Hirschman’s influential theory of ‘exit, voice and loyalty’, which made it possible to see viewing choices audiences make as an act of agency, in combination with theoretical tools developed within the framework of social constructionist approaches to national imagination and broadcasting, my study focuses on the investigation of responses publics of the Latvian public television LTV have developed vis-à-vis its role as contributing to the nation-building project in this ex-Soviet Baltic country. With the help of focus groups methodology and family ethnography, the thesis aims to explore the relationship between the way members of the ethno-linguistic majority of Latvian-speakers and the sizeable ethno-linguistic minority of Russian-speakers conceptualize the public broadcaster LTV, as well as understand the concept of public broadcasting more generally, and the way they define the national ‘we’. The study concludes that what I call publics of LTV employ Hirschman’s described exit mechanism as a voice-type response. Through their rejection of public television which, for a number of complex reasons they consider to be a state broadcaster serving the interests of those in power they voice their protest against the country’s political establishment and in the case of its Russian-speaking publics also against the government’s ethno-nationalistic conception of the national ‘we’. I also find that though having exited from the public broadcaster LTV, its publics have not abandoned the idea of public broadcasting as such. At least at a normative level the public broadcasting ideals are recognized, accepted and valued, though they are not necessarily associated with the country’s de jure institutional embodiment of public broadcasting LTV. Rejection of the public television has also not made its non-loyal publics ‘less citizens’. The commercial rivals of LTV, be they national or, in the case of Russian-speaking audiences, localized transnational Russian television, have allowed their viewers to exercise citizenship and be loyal nationals day in day out in a way that is more liberal and flexible than the hegemonic form of citizenship and national imagination of the public television LTV can offer.
