Regulated and unregulated insider trading around earnings announcements

This paper analyses insider trading behaviour around annual and interim earnings announcements during changing legislative environments in Sweden from 1980 to 2003. Using a unique data set, we are able to explore the nature of insider trading patterns from unregulated to strongly regulated insider trading markets. We find limited evidence of opportunistic insider trading. Insiders seem to be reluctant to sell stocks before positive earnings announcements. They also tend to time their trades in conjunction with an immediate post-announcement period, i.e. “safety trading”, which becomes more evident within stronger legislation environments. Some support for contrarian trading behaviour is also found.

Public Figures and Stalking in the European Context

The paper presents a brief overview of the international scientific research regarding stalking, threats and attacks on public figures. A special focus lies on European research and its tradition. Particular attention is directed towards the concept of pathological fixations on public figures which covers different forms of harassment and aggressive behaviour. A closer look at the history of scientific research and relevant case examples in this area reveals that pathological fixation on public figures is a phenomenon which was described by psychiatrists as early as 150 years ago. As stalking can affect various kinds of public figures, the research presented here covers stalking of celebrities, politicians, corporate figures and royals who become the victim of harassment or violent attacks. Finally, the state of the art regarding the management of public figure stalking and harassment and the prevention of assassinations by fixated persons in Europe is reviewed.     

The economic effects of direct democracy—a first global assessment

This is the first study that assesses the economic effects of direct democratic institutions on a cross-country basis. We find that total spending as well as spending on welfare is lower in countries with mandatory referendums, consistent with the previous literature. But we also find that countries with national initiatives appear to spend more and be more corrupt. Finally, budget deficits, government effectiveness, productivity and “happiness” appear unrelated to direct democracy. Institutional detail thus matters a great deal. In general, the effects of direct-democratic institutions become stronger if the frequency of their actual use is taken into account. Effects are usually stronger in countries with weak democracies.     

Shaping Political Preferences: Information Effects in Political-Administrative Systems

Information is at the heart of politics. However, since information is always sent by someone who is more or less powerful, it is difficult to disentangle the effect of information from the power of the sender. Drawing on a standard model of attitude formation, we argue that presenting information can affect preferences of politicians regardless of the power of the sender. We test this proposition in a survey experiment with 1205 Danish local politicians in which the experimental groups were presented with varying levels of cost information but where sender remained constant. The experiment shows that even in a setting where the information is not disclosed by a powerful sender, information may have a stronger impact on political preferences than other well-known determinants such as committee and party affiliation. Our findings speak to learning theories, knowledge perspectives and the literature on the determinants of politicians’ preferences.     

The breakdown of the sex/gender distinction in anthropological discourse

This contribution to the ongoing process of questioning the sex/gender distinction in feminist research sets out from two different points of departure. First, from an anthropological perspective, examples are given to help us “rethink” sex as a universal “given”. Second, it is examined how the distinction, when used in feminist analyses, has confused rather than clarified our understanding of sex/gender. Finally, the implications of the breakdown of the sex/gender distinction for feminist research are discussed in brief.

The Role of Assessments and Institutions for Policy Learning: A Study on Swedish Climate and Nuclear Policy Formation

This study examines two challenges related to the integration of environmental concerns into public policymaking: how to shape institutions that facilitate policy learning in national policymaking processes, and how to create effective supporting assessment processes. A simple construct of policy learning is applied empirically; distinguishing what is learned in terms of conceptual and technical learning, and unpacking the process of learning into three elements: knowledge acquisition, interpretation, and institutionalization. Two empirical policy cases, climate and nuclear policy formation in Sweden, are analyzed over two decades, detecting patterns of learning and investigating what institutions have facilitated or obstructed them. The analysis is based on a study of actual policy outputs, an examination of reasoning and argumentation in policy documents, and evidence from testimonial interviews. Results indicate that climate policy has undergone fundamental learning processes whereas nuclear policy has been more intractable. Most learning has occurred in some agency and committee processes, while ministries and political levels have suffered from weak capacities and incentives to learn. Key drivers of learning included trust building among key agents coupled to international driving forces. Ultimately, institutional rules, capacities, and incentives are more important factors for enhancing learning than what types of assessments feed in.     

Y-chromosome STR haplotypes in Sweden

A total of 708 men, with Swedish names, from different parts of Sweden have been typed for the Y-chromosome minimal haplotype STR markers DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393 and DYS385. Of these, 403 men were of geographically undefined Swedish origin and the rest, 305, from seven defined geographical regions. PCR-products were detected by ABI377 using sequenced allelic ladders. An evaluation of the 708 chromosomes revealed 423 different haplotypes. Only 100 of the haplotypes were found more than once. The over all haplotype diversity was 0.994. The haplotype 14, 12, 28, 23, 10, 11, 13, 14-14 has the highest frequency of 5.79% and is significantly Swedish, when compared to other European populations.     

Nuclear and mitochondrial DNA quantification of various forensic materials

Due to the different types and quality of forensic evidence materials, their DNA content can vary substantially, and particularly low quantities can impact the results in an identification analysis. In this study, the quantity of mitochondrial and nuclear DNA was determined in a variety of materials using a previously described real-time PCR method. DNA quantification in the roots and distal sections of plucked and shed head hairs revealed large variations in DNA content particularly between the root and the shaft of plucked hairs. Also large intra- and inter-individual variations were found among hairs. In addition, DNA content was estimated in samples collected from fingerprints and accessories. The quantification of DNA on various items also displayed large variations, with some materials containing large amounts of nuclear DNA while no detectable nuclear DNA and only limited amounts of mitochondrial DNA were seen in others. Using this sensitive real-time PCR quantification assay, a better understanding was obtained regarding DNA content and variation in commonly analysed forensic evidence materials and this may guide the forensic scientist as to the best molecular biology approach for analysing various forensic evidence materials.
