Social Divisions and Coercive Control in Advanced Societies: Law Enforcement Strength in Eleven Nations from 1975 to 1994.

Conflict theory suggests that economic stratification poses a threat to order, so we should expect increased inequality to lead to a greater capacity for coercive control. The police are the primary agency that uses force to preserve order, yet we know little about the effects of economic divisions on police size in advanced nations besides the United States. The generality of findings based on a fixed-effects panel design applied to 11 developed nations should provide increased insight about how coercion is used to preserve domestic order. Other social divisions that should matter include minority presence and unemployment. With economic development, urbanism, crime, and social disorganization held constant, economic inequality and crime rates in the last years of the sample matter, but minority presence explains police strength only in the United States. The results suggest that threats to internal stability due to economic stratification are most likely to produce subsequent expansions in formal social control. These findings should help resolve disputes about which potentially destabilizing social divisions provide the most general explanation for shifts in the strength of state agencies that specialize in domestic control

Minority Threat And Police Strength From 1980 To 2000: A Fixed-Effects Analysis Of Nonlinear And Interactive Effects In Large U.S. Cities

Many studies have assessed threat theory by investigating the relationships between the size of minority populations and police strength. Yet these investigations analyzed older data with cross-sectional designs. This study uses a fixed-effects panel design to detect nonlinear and interactive relationships between minority presence and the per capita number of police in large U.S. cities in the last three census years. The findings show that the relationship between racial threat and the population-corrected number of police officers has recently become considerably stronger. In accord with theoretically based expectations, tests for interactions show that segregated cities with larger African American populations have smaller departments. The coefficients on another interaction effect suggest that racial segregation leads to reductions in police strength in the South perhaps because officers are less likely to intervene in residentially isolated black neighborhoods in this region

The Determinants of Executions Since 1951: How Politics, Protests, Public Opinion, and Social Divisions Shape Capital Punishment

This time-series study uses hypotheses derived from a politically refined version of conflict theory to explain both public support for the death penalty and the number of executions. With murders in death penalty states and Supreme Court decisions held constant, tests of hypotheses about lags suggest that public support and Republican strength in the states influence yearly executions by their effects on death sentences rather than the later appeals process. Other dynamic results show that national level Republican strength, presidential elections that emphasize law and order, economic inequality, and higher murder rates increase yearly executions because they affect the extremely influential but later appeals process. Civil rights protests, however, immediately reduce both public support and executions. Although minority threat enhances public support for capital punishment, this contextual factor does not explain executions. These results are unique as no prior studies have assessed the conditions that determine how often the harshest punishment is used

A new ophthalmosaurid ichthyosaur from the Upper Jurassic (Early Tithonian) Kimmeridge Clay of Dorset, UK, with implications for Late Jurassic ichthyosaur diversity

A new ophthalmosaurid ichthyosaur, Thalassodraco etchesi gen. et sp. nov., from the Upper Jurassic Kimmeridge Clay Formation of Dorset, UK is described. The specimen, a partial, articulated skull and anterior thorax in the Etches Collection of Kimmeridge, Dorset, is exceptionally well preserved on a slab of laminated coccolith limestone and has been expertly prepared. It comprises a near complete skull in articulation with associated anterior vertebral column and dorsal ribs, complete pectoral girdle, fully exposed left forelimb, and some elements of the right forelimb. Other elements present, including an ischiopubis are preserved on separate slabs. Presumed rapid burial of the anterior portion of the specimen in the coccolith substrate has preserved a number of ossified ligaments lying across the vertebral column and associated ribs as well as stomach contents and decayed internal organs. Aspects of the dentition, skull roof bones and the forelimb configuration distinguishes the new specimen from previously described Late Jurassic ichthyosaurs. Autopmorphies for T. etchesi include a large rounded protuberance on the supratemporal bone; a thin L-shaped lachrymal, with a steeply curved posterior border; ~ 70 teeth on the upper tooth row, and deep anterior dorsal ribs. A well resolved phylogenetic analysis shows T. etchesi as a member of a basal clade within Ophthalmosauridae comprising Nannopterygius, Gengasaurus, Paraophthalmosaurus and Thalassodraco. The new specimen adds to the diversity of the Ichthyopterygia of the Kimmeridge Clay Formation and emphasises the important contribution of amateur collectors in palaeontology

In vivo Detection of Hyperoxia-induced Pulmonary Endothelial Cell Death Using \u3csup\u3e99m\u3c/sup\u3eTc-Duramycin

Introduction 99mTc-duramycin, DU, is a SPECT biomarker of tissue injury identifying cell death. The objective of this study is to investigate the potential of DU imaging to quantify capillary endothelial cell death in rat lung injury resulting from hyperoxia exposure as a model of acute lung injury. Methods Rats were exposed to room air (normoxic) or \u3e 98% O2 for 48 or 60 hours. DU was injected i.v. in anesthetized rats, scintigraphy images were acquired at steady-state, and lung DU uptake was quantified from the images. Post-mortem, the lungs were removed for histological studies. Sequential lung sections were immunostained for caspase activation and endothelial and epithelial cells. Results Lung DU uptake increased significantly (p \u3c 0.001) by 39% and 146% in 48-hr and 60-hr exposed rats, respectively, compared to normoxic rats. There was strong correlation (r2 = 0.82, p = 0.005) between lung DU uptake and the number of cleaved caspase 3 (CC3) positive cells, and endothelial cells accounted for more than 50% of CC3 positive cells in the hyperoxic lungs. Histology revealed preserved lung morphology through 48 hours. By 60 hours there was evidence of edema, and modest neutrophilic infiltrate. Conclusions Rat lung DU uptake in vivo increased after just 48 hours of \u3e 98% O2 exposure, prior to the onset of any substantial evidence of lung injury. These results suggest that apoptotic endothelial cells are the primary contributors to the enhanced DU lung uptake, and support the utility of DU imaging for detecting early endothelial cell death in vivo

Vigilantism, Current Racial Threat, and Death Sentences

Capital punishment is the most severe punishment, yet little is known about the social conditions that lead to death sentences. Racial threat explanations imply that this sanction will be imposed more often in jurisdictions with larger minority populations, but some scholars suggest that a tradition of vigilante violence leads to increased death sentences. This study tests the combined explanatory power of both accounts by assessing statistical interactions between past lynchings and the recent percentage of African Americans after political conditions and other plausible effects are held constant. Findings from count models based on different samples, data, and estimators suggest that racial threat and lynchings combine to produce increased death sentences, but the presence of liberal political values explains the absence of death sentences. These findings both confirm and refine the political version of conflict theory because they suggest that the effects of current racial threat and past vigilantism largely directed against newly freed slaves jointly contribute to current lethal but legal reactions to racial threat

Sensory drive mediated by climatic gradients partially explains divergence in acoustic signals in two horseshoe bat species, Rhinolophus swinnyi and Rhinolophus simulator

Geographic variation can be an indicator of still poorly understood evolutionary processes such as adaptation and drift. Sensory systems used in communication play a key role in mate choice and species recognition. Habitat-mediated (i.e. adaptive) differences in communication signals may therefore lead to diversification. We investigated geographic variation in echolocation calls of African horseshoe bats, Rhinolophus simulator and R . swinnyi in the context of two adaptive hypotheses: 1) James' Rule and 2) the Sensory Drive Hypothesis. According to James' Rule body-size should vary in response to relative humidity and temperature so that divergence in call frequency may therefore be the result of climate-mediated variation in body size because of the correlation between body size and call frequency. The Sensory Drive Hypothesis proposes that call frequency is a response to climate-induced differences in atmospheric attenuation and predicts that increases in atmospheric attenuation selects for calls of lower frequency. We measured the morphology and resting call frequency (RF) of 111 R . simulator and 126 R . swinnyi individuals across their distributional range to test the above hypotheses. Contrary to the prediction of James' Rule, divergence in body size could not explain the variation in RF. Instead, acoustic divergence in RF was best predicted by latitude, geography and climate-induced differences in atmospheric attenuation, as predicted by the Sensory Drive Hypothesis. Although variation in RF was strongly influenced by temperature and humidity, other climatic variables (associated with latitude and altitude) as well as drift (as suggested by a positive correlation between call variation and geographic distance, especially in R . simulator ) may also play an important role
