Hacking trauma is prevalent in forensic cases involving genocide and dismemberment, but research into the identification of this type of trauma is lacking. The present study examines characteristics of hacking and blunt force skeletal trauma in order to determine if there is a point at which blunt force trauma becomes distinguishable from hacking trauma. Ten implements with a range of blade angles (i.e., the striking surface of the implement) were used in conjunction with a controlled-force hacking device to impact 100 limb bones of white-tailed deer (Odocoileus virginianus). Observations of the trauma included the occurrence and degree of fragmentation, the entrance widths of the impacts, and composite scores of six hacking characteristics, especially the distinctive V-shaped kerf. ANOVA tests and regression analyses were used to assess the relationships between these characteristics and the blade angles. A significant relationship (p-value = 0.011) was found between the composite hacking scores and the blade angles, indicating that blunt force and hacking trauma can be distinguished. The entrance widths of the impacts exhibited a significant relationship with the blade angles (p-value = 0.037). There was also a significant relationship between the visibility of a V-shaped kerf in the bones (p-value = 0.003), with visibility decreasing around the 60° blade angle. These data should assist in establishing guidelines to differentiate hacking and blunt force skeletal trauma in cases where the implement is on a spectrum between sharp and blunt. 相似文献

What politicians devote attention to, is an important question as political attention is a precondition of policy change. We use an experimental design to study politicians’ attention to incoming information and deploy it among large samples of elected politicians in three countries: Belgium, Canada, and Israel. Our sample includes party leaders, ministers and regular members of parliament. These elites were confronted with short bits of summary information framed in various ways and were then asked how likely it was that they would read the full information. We test for three frames: conflict, political conflict, and responsibility. We find that framing moderates the effect of messages on politicians’ attention to information. Politicians react more strongly (i.e., they devote more attention) to political conflict frames than to non-political conflict frames and they react stronger to political responsibility attributions than to non-political responsibility attributions. Conflict frames attract more attention than consensus frames only from members of opposition parties. Political conflict frames attract more attention from government party politicians. These effects occur largely across issues and across the three countries. 相似文献

Party politics and electoral research generally assume that party members are loyal voters. This article first assesses the empirical basis for this assumption before providing individual‐level explanations for defection. It combines prominent theories from party politics and electoral behaviour research and argues that internal disagreement and external pressure can each bring about disloyal voting. The hypotheses are motivated with multi‐country European survey data and tested on two sets of party‐level national surveys. The results show, first, that, on average, 8 per cent of European party members cast a defecting vote in the last election, and second, that dissatisfaction with the leadership is the strongest predictor of defection. Additionally, internal ideological disagreement is associated with higher probabilities of defection, whereas the effects of pull factors in the form of contentious policies are rather limited. These findings emphasise the importance of testing scientific assumptions and the potential significance of party leadership contests. 相似文献

This study analyzes the short‐term impact of an exogenous, positive income shock on caregivers’ subjective well‐being (SWB) in Malawi using panel data from 3,365 households targeted to receive Malawi's Social Cash Transfer Program that provides unconditional cash to ultra‐poor, labor‐constrained households. The study consists of a cluster‐randomized, longitudinal design. After the baseline survey, half of these village clusters were randomly selected to receive the transfer and a follow‐up was conducted 17 months later. We find that the short‐term impact of household income increases from the cash transfer leads to substantial SWB gains among caregivers. After a year's worth of transfers, caregivers in beneficiary households have higher life satisfaction and are more likely to believe in a better future. We examine whether program impacts on consumption, food security, resilience, and hopefulness could explain the increase in SWB but do not find that any of these mechanisms individually mediate our results. 相似文献

Governments have historically offered their workforce a public service bargain founded on stable pay and conditions and job security. However, while the Westminster system aims for public service employment to be protected from the whims of government, public servants are nonetheless affected by the political environment in which they operate and changes to this bargain can occur with a new government. This paper focuses on a Queensland public service change process that resulted in large‐scale forced redundancies, non‐renewal of temporary contracts, and legislative changes that nullified the provisions in job security, organisational change, and redundancy policies. Using communication as a lens through which to understand leadership, it examines how the government communicated with the public service about this organisational change, immediately before and after the 2012 election. In particular, through analysis of public and media commentary, speeches and Hansard records, it examines Premier Newman's change leadership and communication by contrasting pre‐election messages to the public service with post‐election messages about the public service and the justifications for change during this period of downsizing. This analysis is used to reflect on political leadership, communication, fair treatment, and trust in public service change. 相似文献

When a policy sector is confronted with a relatively strong and steep decline in legitimacy, we speak of an institutional crisis. We know little about the causes or consequences of these crises. This article explores how institutional crises are managed. It focuses on the effects of management strategies observed in a case study of an institutional crisis in the Netherlands. While we found that policy elites displayed a tendency to maintain the status quo of a policy sector, we also found that the effectiveness of their response strategies was negated by the counter‐response it evoked among freshly energized interest, advocacy and citizen groups. We conclude that the resolution of an institutional crisis is inherently contested. Based on our case study, we develop a theoretical model and formulate propositions that may help to improve our understanding of institutional crisis management. 相似文献

For the last two decades, performance management theories and practices have focused on outcome‐oriented management but have paid little attention to the role of public communication. Using multiple large data sets from Kansas City, Missouri, for 2009–14, this research suggests that the perceived effectiveness of public communication has a more substantial impact on public satisfaction with police protection and crime prevention than neighborhood crime rates and broken windows factors and that perceived effectiveness moderates the negative impact of crime rates. After controlling for residents’ demographic characteristics, the authors find that the perceived effectiveness of communication is associated with public satisfaction with the content and quality of the city website and the government television channel. The implications for public safety management and police–citizen relations as well as directions for future research on public communication strategies and public performance management are presented. 相似文献

This article seeks to place the UK's present economic ‘moment’ in historical context. Over the course of the decade since the 2007 financial crisis, it has increasingly been acknowledged that a cyclical crisis has become a structural crisis. The failure of most economists to predict the financial crash in the first place, and the inadequacy of economic policy in responding to its lasting effects, has led many to conclude that economics itself is in crisis. This article seeks to contribute to a better understanding of the present period of disjuncture. Drawing on theories of paradigm shift from both the physical and social sciences, we argue that the speed of change in UK economic policy is comparable to the two major historical transitions that ended with the post‐war consensus and neoliberalism. We conclude by offering some remarks on how and where the present change might take us. 相似文献

Individuals are the single largest source of campaign contributions, yet we know little about their motivations. For instance, the existing literature questions whether individual contributors sophisticatedly differentiate among candidates according to policy positions, particularly among same‐party candidates. We analyze this issue by combining data from a new survey of over 2,800 in‐ and out‐of‐state donors associated with the 2012 Senate elections, FEC data on contributors’ professions, and legislative records. Three major findings emerge. First, policy agreement between a donor's positions and a senator's roll calls significantly influences the likelihood of giving, even for same‐party contributors. Second, there is a significant effect of committee membership corresponding to a donor's occupation; this holds even for donors who claim that other motivations dominate, but it does not appear to be motivated by an expectation of access. Third, conditional upon a donation occurring, its size is determined by factors outside a legislator's control. 相似文献
