Metrological framework for selecting morphological characters to identify species and estimate developmental maturity of forensically significant insect specimens

Accurate age estimates of immature necrophagous insects associated with a human or animal body can provide evidence of how long the body has been dead. These estimates are based on species-specific details of the insects’ aging processes, and therefore require accurate species identification and developmental stage estimation. Many professionals who produce or use identified organisms as forensic evidence have little training in taxonomy or metrology, and appreciate the availability of formalized principles and standards for biological identification. Taxonomic identifications are usually most readily and economically made using categorical and qualitative morphological characters, but it may be necessary to use less convenient and potentially more ambiguous characters that are continuous and quantitative if two candidate species are closely related, or if identifying developmental stages within a species. Characters should be selected by criteria such as taxonomic specificity and metrological repeatability and relative error. We propose such a hierarchical framework, critique various measurements of immature insects, and suggest some standard approaches to determine the reliability of organismal identifications and measurements in estimating postmortem intervals. Relevant criteria for good characters include high repeatability (including low scope for ambiguity or parallax effects), pronounced discreteness, and small relative error in measurements. These same principles apply to individuation of unique objects in general.

Key points

• Metrological rigour can increase in forensic entomology by selecting measurements based on their metrological qualities.
• Selection of high-quality features for morphological identification of organisms should consider these criteria: (1) pronounced discreteness of features (minimising group overlap or maximizing interval); (2) high repeatability of assessment (such as symmetrical width rather than asymmetrical length); (3) small relative error in measurement (selecting the physically largest continuous rigid feature for measurement).
• These metrological principles also apply to individuation of unique objects in general.

     

Power and changing modes of governance in the euro crisis

Which European Union actors are most powerful in the governance of the euro crisis? The euro crisis has reignited the classic debate between intergovernmentalists, who tend to stress the coercive power of dominant member states in the European Council, and supranationalists, who maintain that through the use of institutional power, the Commission, and the European Central Bank turned out the “winners” of the crisis. This article argues that euro crisis governance is best understood not just in terms of one form of power but instead as evolving through different constellations of coercive, institutional, and ideational power that favored different EU actors over the course of the crisis, from the initial fast‐burning phase (2010–2012), where the coercive and ideational power of Northern European member states in the European Council was strongest, to the slow‐burning phase (2012–2016), when greater influence was afforded supranational actors through the use of ideational and institutional power.     

The Czech Islamophobic movement: beyond ‘populism’?

ABSTRACT

Sla?álek and Svobodová’s paper focuses on the ideology of the Czech Islamophobic movement as seen during the 2015–16 migration crisis. In their analysis of interviews with demonstrators and speeches by leaders of the movement, they discuss first how the movement imagined its enemies, and then describe its vision of positive core values. They conclude that the movement’s key ideological features are: an emphasis on social and civilizational decline (declinism); a return to an assumed naturalness in economic and gender relationships (naturalization); and the open evocation of violence and severity (brutalization). In terms of Rogers Brubacker’s distinction between xenophobic ethno-nationalism in Eastern Europe, and the xenophobic defence of liberal values in the West, Sla?álek and Svobodová find that the Czech case fits the allegedly western pattern better than the eastern one, which may cast doubt on the whole essentialization of distinctions between ‘western’ and ‘eastern’ populisms.     

The political economy of churches in Denmark, 1300–2015

This paper reports new time-series for the numbers and sizes of churches in Denmark over a 715-year period. Per capita, the new series are termed church densities. A pattern emerges in the series that corresponds to the main development in the economy: until 1750, the economy was in the traditional steady state, where church densities were high and did not decline substantially. Modern development set in after 1750. Since then, church densities have declined more than five times. Moreover, capacity utilization of church rooms has declined, which means that the reduction in the demand for churches must have been even larger. We argue that this large decline is caused by a fall in religiosity that is caused by economic development as measured by the rise in incomes. In parallel with similar transitions in other sectors, e.g., the Agricultural Transition, it is termed the Religious Transition.     

TTIP and legislative‒executive relations in EU trade policy

Abstract

This paper analyses Transatlantic Trade and Investment Partnership (TTIP) negotiations in order to assess how the move towards tighter economic integration within the EU?US strategic partnership impacts on legislative?executive relations in EU trade policy. The analysis examines the institutional, substantive and party political dimensions of national parliaments’ scrutiny of the Common Commercial Policy. Based on insights into both domestic and EU channels of parliamentary monitoring of TTIP negotiations, the paper argues that, although the government remains the central object of democratic control, the involvement of national parliaments in transatlantic trade extends to encompass the EU’s own transatlantic and trade policies. This is rooted in the legislatures’ legal capacity to constrain the executive in the negotiation, conclusion and, where applicable, ratification phases of EU trade agreements. It is argued that national parliamentary influence takes the shape of politicisation of the legitimacy of the expected policy outcomes of these agreements.     

Path-to-Citizenship or Deportation? How Elite Cues Shaped Opinion on Immigration in the 2010 U.S. House Elections

The ascendency of immigration as an issue in elections has been concomitant with massive increases in the Hispanic population in the U.S. We examine how immigration cues prompt greater or lesser levels of restrictionist sentiment among individuals, showing demographic context conditions the effect of candidates cues. Using data from the 2010 U.S. House elections, we illustrate cues presented in new destination states—states with massive increases in the size of the Hispanic population from 1990 to 2010—have a larger impact on individuals’ immigration preferences than cues presented in non-new destination contexts. We show candidates with more extreme immigration positions are more likely to prioritize the issue of immigration in their campaigns, suggesting campaign prioritization of immigration has a directional cue. We conclude these directional cues from Republican candidates in new destination contexts move individual attitudes toward restrictionist preferences.     

Conceptions of the good,rivalry, and liberal neutrality

Liberal neutrality is assumed to pertain to rival conceptions of the good. The nature of the rivalry between conceptions of the good is pivotal to the coherence, scope and realisation of liberal neutrality. Yet, liberal theorists have said very little about rivalry. This paper attempts to fill this gap by reviewing three conceptions of rivalry: incompatibility rivalry, intra-domain rivalry and state power rivalry. I argue that state power rivalry is the morally relevant conception of rivalry, and that it has significant implications for the scope and realisation of liberal neutrality. I conclude that in the light of state power rivalry, the only feasible liberal neutral state is a very minimal one.
