Differential Ability of Necrophagous Diptera to Colonize Concealed Resources: Empirical Evidence From a Field Experiment in Brazil

Field studies in forensic entomology seem to assume that a cadaver is a resource equally accessible to flies, irrespective of the species’ size, behavior, and sensorial capacity. We aimed to challenge this assumption by experimentally manipulating baited traps in order to test whether the accessibility to decomposing baits is related to the following: (i) the diversity of necrophagous dipterans; (ii) the body size of adults; and (iii) the female sexual maturity stage. The experiment was performed in a rainforest fragment in Northeastern Brazil, in an area characterized by high levels of homicides. Traps baited with decomposing chicken liver had three levels of access: easy (six openings on the trap), intermediate (three), and difficult (one). A total of 750 adults of Calliphoridae, Fanniidae, Muscidae, Phoridae, and Sarcophagidae were collected. Of the 18 species recorded, Megaselia scalaris was the most abundant (46.8%) followed by Lucilia eximia (29.7%) and Chrysomya megacephala (9.8%). The number of species increased significantly with the accessibility level, but overall abundance did not differ, as a consequence of the numerical dominance of M. scalaris. A strong female bias (>91%) was observed in all traps. For Calliphoridae specimens, 90% of the females caught in traps under intermediate and difficult access were sexually mature. By empirically demonstrating that limitation of access and exclusion of visual stimuli do not deter several dipteran species from reaching a substrate, we expand the knowledge on the factors that can shape the colonization of concealed human cadavers, including variables such as insect size and stage of sexual maturity.     

Defending popular sovereignty: discursive conflict in French and Swedish parliamentary debates on immigrant voting rights (1968-2017)

ABSTRACT

Through a discourse analysis of French and Swedish legislative debates from 1968 to 2017, this article examines how actors challenge and reinforce dominant ideas about the link between nationality and political rights. We argue that the broader political culture influences which discursive strategies – or ‘frames’ – are more likely to structure parliamentary debates in different national contexts. However, our analysis also shows that legislators sometimes develop new discursive frames in which they reinterpret dominant norms to make them consistent with their views. Through this incremental process of reinterpretation and reformulation of dominant ideas, debates over non-citizen voting rights have chipped away at the link between nationality and political rights. Our findings suggest that initiatives to enfranchise non-citizens trigger lower levels of conflict when they can be framed as a policy tool for immigrant integration rather than as a matter of popular sovereignty.     

Breaking the Law to Ensure Order: The Case of Tijuana (2007–2012)

This paper explores how state agents and civilians justify human rights violations when the military perform police tasks. Based on a set of interviews and documents, it analyses the actions of the armed forces and the police during a military-led operation that targeted drug trafficking organisations in Tijuana. In a context of limited civilian control over the armed forces and the police, the paper identifies two discourses that supported the illegal action of state agents: the construction of a foreign other who does not belong to society and the need to use violence to accomplish a greater good.

Judicial review of regulatory decisions: Decoding the contents of appeals against agencies in Spain and the United Kingdom

Despite the important role that courts play to supervise the legality of regulatory agencies' actions, only few comparative studies analyze the contents of judicial appeals against regulatory decisions within European countries. This paper builds on the comparative administrative law scholarship and administrative capacities literature to analyze the content of 2,040 rulings against decisions issued by competition and telecommunications regulators in Spain and the United Kingdom. To understand the substance of the appeals, the study classifies cases according to the alleged administrative principles under breach and the regulatory capacities under challenge. Findings show a clear country-sector variation regarding the information contained in judicial disputes for both dimensions of analysis, which can be explained as a result of existing differences between the institutional settings of courts. These results offer a more in depth understanding of the political role of judicial oversight over regulatory agencies embedded in different institutional arrangements and policy sectors.
