Social Media Engagement of Berlin and Prague Museums

ABSTRACT

Attracting visitors and engaging them effectively in the highly competitive and saturated environment shaped by Web 2.0 and online social networking forces museums to creatively and purposefully examine channels for extended interaction with audiences. This exploratory and comparative research aims to compare the state of social media strategies across museums of two regions and to identify the influence of applied strategies on users’ reactions. The surveyed sample considers 296 museums from two European capitals—Berlin and Prague—whose activity has been observed during a three-month period. The findings identify the differences in the approaches of museums and suggest that the frequency and characteristics of published messages correlate to the level of fan reactions, facilitating targeted relationship-building possibilities with online audiences. They further imply that the museums can influence the engagement of visitors by focusing on the particular properties of their posts, both in the sense of post structure, media application, and underlying semantic features.     

A brief measure of the triarchic model of psychopathy among community youths: psychometrics and measurement invariance

ABSTRACT

The development and validation of empirically sound measures that operationalize the Triarchic model of psychopathy among youth is currently in the nascent stage. The present study aimed to examine the psychometric properties of a brief refined measure of the Triarchic model of psychopathy based on the Youth Psychopathic Traits Inventory (YPI-Tri-S) among a mixed-gender school sample of 782 youth (M?=?15.87 years, SD?=?1.72) from Portugal. Confirmatory factor analysis offered support for the theoretically expected three-factor structure. Cross-gender measurement invariance using the present sample and cross-sample measurement invariance of the YPI-Tri-S using a previously collected forensic sample of institutionalized males was established. The YPI-Tri-S showed adequate psychometric properties in terms of discriminant validity, convergent validity, concurrent criterion-related validity, known-groups validity, and internal consistency. Findings indicate that YPI-Tri-S is a valuable brief and psychometrically reliable and valid self-report measure of the Triarchic model of psychopathy for use in diverse samples of youth.     

Rapid determination of scopolamine in evidence of recreational and predatory use

In recent years, scopolamine has become a drug of common use for recreational and predatory purposes and several ways of administration have been devised. A method for the rapid analysis of suspicious samples was developed, using a portable capillary electrophoresis with contactless conductivity detection. The method allows the separation of scopolamine from atropine which has a similar structure and is present along with scopolamine in some samples. The method was demonstrated to be useful for the fast analysis of several types of evidential items which have recently been reported to have been abused with fatal consequences or employed for criminal purposes. An infusion of Datura stramonium L., in which scopolamine and atropine naturally coexist, was analyzed for being frequently consumed for recreational purposes. A spiked moisturizing cream and six spiked alcoholic beverages were also analyzed. In spite of the complexity of the specimens, the sample pre-treatment methods developed were simple and fast.     

Using Bayes’ theorem in behavioural crime linking of serial homicide

Purpose. The study extends research by Santtila et al. (2008) by investigating the effectiveness of linking cases of serial homicide using behavioural patterns of offenders, analysed through Bayesian reasoning. The study also investigates the informative value of individual behavioural variables in the linking process. Methods. Offender behaviour was coded from official documents relating to 116 solved homicide cases belonging to 19 separate series. The basis of the linkage analyses was 92 behaviours coded as present or absent in the case based on investigator observations on the crime scene. We developed a Bayesian method for linking crime cases and judged its accuracy using cross‐validation. We explored the information added by individual behavioural variables, first, by testing if the variable represented purely noise with respect to classification, and second, by excluding variables from the original model, one by one, by choosing the behaviour that had the smallest effect on classification accuracy. Results. The model achieved a classification accuracy of 83.6% whereas chance expectancy was 5.3%. In simulated scenarios of only one and two known cases in a series, the accuracy was 59.0 and 69.2%, respectively. No behavioural variable represented pure noise but the same level of accuracy was achieved by analysing a set of 15, as analysing all 92 variables. Conclusion. The study illustrates the utility of analysing individual behavioural variables through Bayesian reasoning for crime linking. Feasible applied use of the approach is illustrated by the effectiveness of analysing a small set of carefully chosen variables.     

No Evidence of Specific Deterrence under Penal Moderation: Imprisonment and Recidivism in Finland

International literature on prison effects on recidivism tends to find little evidence of specific deterrence. If anything, imprisonment seems more likely to increase than decrease rates of offending. The present study adds to this literature by examining imprisonment and recidivism in Finland, a nation characterized by an exceptionally moderate penal culture. It has been suggested that severe sanctions need to be imposed selectively in order for them to be effective. In this research, we estimated the impact of first imprisonment on recidivism in comparison with offenders sentenced to either suspended imprisonment or community service. Using data from government population registries, we controlled for a large number of legal and extra-legal confounding factors, including criminal history and socio-demographic characteristics. We found no evidence of reduced recidivism as a result of imprisonment. Instead, consistent with prior research, we find evidence of increased recidivism in certain offender categories. We conclude with a discussion of policy implications.     

Problems and Prospects for the Convention on the Conservation of Antarctic Marine Living Resources Twenty Years On*

Abstract

Twenty years after its adoption, the Convention on the Conservation of Antarctic Marine Living Resources (CCAMLR) remains unique among fisheries agreements in its declared commitment to considering the impact of existing or proposed fisheries on the entire ecosystem, rather than on just the harvested species. However, the recent picture of fisheries activities within the Convention area suggests a substantial ‐ and perhaps widening ‐ gap between theory and practice. The fishery that has most clearly proven beyond CCAMLR's capacity, and which has resulted in the most significant damage to the Antarctic environment in modern times is that for Patagonian Toothfish, Dissostichus eleginoides. That fishery is discussed in more detail below. The roots of that problem in conjunction with structural problems that have contributed to CCAMLR's inability to deal with the toothfish challenge threaten to be repeated in the second‐generation krill fishery that is rapidly developing in Antarctic waters. The authors provide suggestions for structural and procedural changes within CCAMLR to permit it to effectively manage the marine living resources of the Southern Ocean.     

The Populist Radical Right and European Integration: A Comparative Analysis of Party–Voter Links

This article analyses the links between populist radical right parties and their voters regarding European integration in 11 European countries. It does so by using data from the 2008 European Social Survey and the 2006 UNC-Chapel Hill Expert Data Base on political parties and European integration. In addition to mapping the Eurosceptic orientations of political parties and their voters, the article examines the degree to which attitudes towards the EU and voting for populist radical parties are connected to each other. The results lend support to the hypothesis that most populist radical right parties have managed to establish links with their voters regarding European integration. The analysis also shows that links between populist radical right parties and their voters tend to be stronger for those parties that adopt more extreme negative positions towards European integration.     

The quality of referendum debate: The UK's electoral system referendum in the print media

This paper analyses the quality of debate surrounding the UK's 2011 electoral reform referendum as represented in the print media. It first considers how debate quality in the context of a referendum campaign may best be conceptualized. It then uses content analysis of media coverage to investigate three aspects of that debate: its quantity; the balance between Yes and No arguments; and the quality of reason-giving. It finds that the quantity of debate was comparable to other recent electoral reform referendums. Coverage was predominantly, but not overwhelmingly, hostile to change. The different indicators of the quality of reason-giving present a mixed picture. The paper concludes by considering how the analysis could be extended through further comparison with other cases.     

Political science,political ideas and rhetoric

The article reviews ‘ideational’ analysis and theory in political science. It argues that this is an important area of research limited by lack of a clear sense of what ideas in politics are and of how to analyse them as directly as possible. It is argued that political science should learn from the ‘rhetorical turn’ in various areas of the social sciences, developing ways, appropriate to political science, of analysing the language, rhetoric and argumentation of political and policy discourse in its governmental contexts. Such an approach rests on a strong sense of the dynamic, contested and creative nature of political activity.
