Death caused by cardioinhibitory reflex cardiac arrest--a systematic review of cases

Forensic pathologists often refer to the cardioinhibitory reflex cardiac arrest (CiRCA) following short neck trauma as a mechanism of death. We sought via a systematic review of the literature to identify circumstances under which carotid bifurcation stimulation could lead to death. Two independent reviewers selected case studies or reports from Medline, ISI Web of Knowledge, and Embase. Circumstances and contributory factors were extracted for each case. From the available data, authors independently assessed whether CiRCA was highly probable (no alternative explanation possible), probable (alternative explanation possible), or unlikely (alternative explanation highly probable). A narrative approach was used to define circumstances in which CiRCA remained possible. From the 48 published cases evoking CiRCA as a possible cause of death between 1881 and 2009, 28 were most likely to result of other mechanism of death (i.e., cerebral hypoxia due to carotid compression, mechanical asphyxia, myocardial infarction). CiRCA remained possible for 20 cases (including five based on anecdotal evidence only) with only one case with no alternative explanation other than CiRCA. Our findings support the presumption that reflex cardiac arrhythmia due to carotid bifurcation stimulation cannot provoke death alone. Actual state of knowledge suggests CiRCA might be contributory to death in the presence of drug abuse and/or cardiac pathology, often associated with physical and/or mental excitation.     

Elasticity in evaluations of criminal evidence: Exploring the role of cognitive dissonance

Purpose. Previous experiments have demonstrated asymmetrical scepticism in investigators' judgments of criminal evidence – evidence inconsistent (vs. consistent) with the dominant hypothesis about a case is judged as less reliable. In addition, some types of evidence (e.g., witness testimony) are more susceptible to asymmetrical scepticism than others (e.g., DNA evidence), indicating varying degrees of elasticity. This article proposes that inconsistent evidence arouses cognitive dissonance, and that the dissonance can be reduced through either asymmetrical scepticism (for high‐elasticity evidence) or belief change (for low‐elasticity evidence). The hypotheses are tested in two experiments. Methods. In both experiments, law students made a preliminary judgment about the guilt of a suspect in a homicide case, and subsequently received a piece of DNA or witness evidence which was either consistent or inconsistent with the preliminary judgment. The extent to which participants changed their guilt judgments, judged the additional evidence as reliable, and felt dissonance served as the main dependent variables. Results. Inconsistent (vs. consistent) evidence did arouse stronger dissonance, but only for witness (and not DNA) evidence. Experienced dissonance (Experiment 1) and dissonance reduction (Experiment 2) accounted for the effect of the evidence on changes in guilt judgments, but not for the effect on reliability judgments. The greatest dissonance reduction was observed among participants who received inconsistent witness evidence but did not change their guilt judgments accordingly. Conclusions. It appears that dissonance plays a significant, although complex, role in investigative judgments of guilt and reliability. Alternative dissonance‐reducing mechanisms that can account for the findings and practical implications are discussed.     

Scanning electron microscopy analysis of experimental bone hacking trauma of the mandible

The authors report on a macroscopic and microscopic study of human mandible bone lesions achieved by a single-blade knife and a hatchet. The aim of this work was to complete the previous data (scanning electron microscopy analysis of bone lesions made by a single-blade knife and a hatchet, on human femurs) and to compare the lesions of the femur with those of the mandible. The results indicate that the mandible is a more fragile bone, but the features observed on the mandible are quite similar to those previously observed on the femur. This work spells out the main scanning electron microscopy characteristics of sharp (bone cutting) and blunt (exerting a pressure on the bone) mechanisms on human bone. Weapon characteristics serve to explain all of these features.     

Public-Sector Reform: Employment Security and Quality of Decision Making in the Australian Taxation Office

This article examines the impact of structural reforms and industrial relations changes on the employment security and decision behaviors of middle-level managers in the Australian Taxation Office (ATO). This article is based on an empirical study using focus group and survey data that investigated how structural change and public-sector reforms substantially altered the employment environment. This research reveals that the ATO environment can be characterized by low morale, risk aversion, fear, and distrust brought about, in part, by employment insecurity. Where middle managers perceived organizational threats to their employment security, they engaged in self-protective “survivor” behaviors even when no such threats to their employment security existed. The article concludes that a substantial number of middle-level managers, survivors of years of restructuring, downsizing, and organizational change, were unlikely to display high-quality decision-making behaviors.     

Fire over water: China's strategic engagement of Somalia and the Gulf of Aden crisis

Abstract

Since China agreed to join the international counter-piracy coalition in late 2008, a watershed development in Chinese strategic policy, Beijing's engagement in Somalia is now following two separate streams. First, China is seeking to engage Somalia as part of its expanding number of African diplomatic partners via its participation in the coalition. Second, China is attempting to demonstrate, on the international level, its growing commitment to developing its naval capabilities, and protecting its maritime trade interests, by engaging in multilateral and coalition-based operations, namely to combat piracy off the Somali coast, in order to deflect criticism from the United States and its allies of China's overall military expansion and modernization.     

Introduction to session 2: Magnitude of the crisis: The fiscal and human costs

Abstract

Many are looking to California and its state housing law for advice on how to deal with the affordability challenges affecting many metropolitan areas throughout the nation. It is thus critically important to go beyond the laws themselves and examine how state and municipal governance structure affects affordability, supply, and production. Some states give broad freedom to localities to develop policies that can potentially meet a range of goals and objectives. Others directly undermine those efforts by limiting local ability to pursue policy reforms while simultaneously failing to engage on the state level.

The redefinition of federalism on the national level, coupled with continued resistance to growth from some localities, establishes the state as at least an equal partner in dealing with housing supply and affordability issues. Understanding these distinctions is important, and the housing community needs to take them into account as it moves on the state front.     

Management Roles in Political and Senior Civil Servant Positions: A Multiple-Study Approach

ABSTRACT

A recent trend in public administration studies has been to assess how public management is performed by politicians and top civil servants. Surprisingly, little is known about how these different posts develop their management roles. Following seminal management studies, we focus on core management roles to compare the ways in which politicians and top civil servants develop their management responsibilities within public organizations. Empirical evidence is provided by triangulating three separate studies developed in Spain. Results from the triangulation show that there is unmistakable evidence of differentiations between politicians and top civil servants when performing their managerial roles.     

Mapping fears: the use of commercial high-resolution satellite imagery in international affairs

In October and November 2001, the Pentagon purchased the rights to all images of Afghanistan taken by the Ikonos remote sensing satellite, a high-resolution satellite owned and operated by Space Imaging, Inc. Ikonos is one of a growing number of privately owned and operated remote sensing satellites. It is suggested that Ikonos and other high-resolution satellites carry at least two challenges to national security policy makers. The first is a challenge to operational security – the ability to plan, prepare and carry out military operations in a controlled information environment. Second, commercial remote sensing presents a political challenge to policy makers. Policy makers today face a greater challenge in their efforts to maintain control over the content of debate concerning national and international security priorities and objectives. It is argued here that the nature of the security policy debate itself is in the midst of a fundamental shift in tone and quality as a result of remote sensing satellite technology. It was principally this latter challenge – and not a concern over operational security – that led to the Pentagon's purchase of all Ikonos images during the opening phases of the war in Afganistan.
