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. 相似文献

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. 相似文献

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. 相似文献

ABSTRACTA 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. 相似文献

Using data from the Philippines, we study the impact of mobile phones on the prices agricultural producers receive for their cash crop. We first look at the impact on price of mobile phone ownership at the household level. Because this masks a considerable amount of heterogeneity, we then look at the impact on price of the intrahousehold allocation of mobile phones. We find that whether the household owns a mobile phone has no impact on price, but whether a farmer or spouse owns a mobile phone is associated with a 5- to 8-per cent increase in price. 相似文献

Abstract This article offers one China analyst's perspective on a variety of questions related to the unionization of all sixty-six Wal-Mart outlets in China. Why did China force Wal-Mart to unionize? If, as Marx, paraphrasing Hegel, wrote, “all great world-historic facts and personages appear, so to speak, twice,” is Mao making his comeback? Or if, as Marx immediately continued in his own right, “He forgot to add: the first time as tragedy, the second time as farce,” is Hu Jintao playing Louis Bonaparte to Mao's Napoleon? Is the Chinese state acting out of a new level of confidence that it can now challenge the world's most prepossessing corporate giants in order to make good on its communist commitments? Is it running scared in the face of a working class that has at last managed to score a victory? Or is it actually strengthening its power through time-honored tactics of mass organizational control that have not really changed despite the new market context? Are China's workers being protected, empowered, or co-opted and subjected to new forms of state control? And why did one of the world's most militantly antiunion corporations go along? Did they have a choice? Did they fear China's state-run union federation? And finally, what does all this portend for the future of labor relations in China? 相似文献

The operation of a motor vehicle requires the integrity of sensory, motor, and intellectual faculties. Impairment of these faculties following the consumption of alcohol has been studied extensively through laboratory, closed‐course and on‐road driving, and epidemiological studies. The scientific literature was reviewed critically, with a focus on low‐to‐moderate blood alcohol concentrations (BAC ≤ 0.100%), to identify the most reliable determinants of alcohol‐impaired driving. Variables such as age, gender, driving skill, and tolerance were shown to have limited impact on impairment. It was concluded the most relevant variables are BAC and complexity of the driving task. The scientific literature provides a high degree of confidence to support the conclusion that a BAC of 0.050% impairs faculties required in the operation of a motor vehicle. Whether impairment is apparent depends upon the complexity of the driving task, which applies to both study design and actual driving. 相似文献

Women's continued political underrepresentation suggests that women candidates might be more likely than men to be ‘sacrificial lambs’ – that is, more likely than men to serve as party standard bearers in districts where their party has little chance to win. Using data from the 2004–2011 Canadian federal elections, we find support for the sacrificial lamb hypothesis when district competitiveness is measured dynamically, rather than statically. Our dynamic measurement of district competitiveness further shows that women incumbents' seats are not as safe as are men's. We conclude that these two factors help to explain why women remain underrepresented in Canadian federal politics. 相似文献
