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.  相似文献

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.

For nearly five decades, the European Court of Justice (ECJ) has developed a decisively pro-European case law and has become the ??engine of integration??. Institutional explanations shed light on the Court??s room for manoevre. They have to be complemented by actor-centered explanations that shed light on the judges?? motives of action. The explanation offered by the following paper is unfolded in two steps. In the first one, the article describes idiosyncrasies of the European law discourse that already shaped the judges before they were appointed. The analysis of the idiosyncrasies corresponds to a scepticism towards the idea of national sovereignty, a belief in the necessity of creative and idealist, law-augmenting judges and a dominance of output-oriented legitimization strategies. In a second step, the article shows that in the sociological sense the ECJ judges constitute a group. While the individual judges share an understanding of the aims and functions of European law, the group develops its own identity and grants status to those who perform successful actions with respect to the common integration agenda. This explanation is more realistic than ??rational choice?? explanations which point to the direct and personal benefits that judges derive from their pro-European case law.  相似文献

This article analyses the conditions of capital accumulation in South Africa, and seeks to explain the authoritarian and racially discriminatory features of the South African social structure in terms of (a) the specific historical processes of change (mercantile colonial conquest, primitive accumulation in mining and farming) and (b) the specific features of contemporary capitalism, notably the capital-intensive structure of industry. The authoritarianism embodied, for example, in the extra-economic coercion of black labour is seen as reflecting the circumstances of the struggle between capital and labour under conditions where capital-labour contradictions exist alongside the contradiction between South African capitalism and the ‘dependent’ societies it has preserved/recreated. The implications of this situation for strategies of socialist change are briefly evaluated.  相似文献

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.  相似文献
