One of the most prominent claims to emerge from the field of public opinion is that citizens can vote for candidates whose issue positions best reflect their own beliefs even when they cannot remember previously learned stances associated with the candidates. The current experiment provides a unique and powerful examination of this claim by determining whether individuals with profound amnesia, whose severe memory impairments prevent them from remembering specific issue information associated with any particular candidate, can vote for candidates whose issue positions come closest to their own political views. We report here that amnesic patients, despite not being able to remember any issue information, consistently voted for candidates with favored political positions. Thus, sound voting decisions do not require recall or recognition of previously learned associations between candidates and their issue positions. This result supports a multiple memory systems model of political decision making. 相似文献

Trust is an important feature for all users of the Internet who rely on the safety and security of network technologies and systems for their daily lives. Trust, or the lack of it, has also been identified by the European Commission’s Digital Agenda as a major barrier to further development of the information society in Europe. One of the areas in which concerns have been raised is in relation to children’s safety online. As a result, substantial efforts have been made by policymakers and by the industry to build greater trust and confidence in online digital safety. This paper examines what trust means in the context of children’s use of the Internet. Should policy on trust enhancement, for instance, include children’s own trust in the technologies or services they use or is it sufficient to seek to reinforce parental and adult confidence that children can be adequately protected? What is required to build that trust from either perspective? Does it need, or should it include a relationship of trust between parents and children? To tease out these questions further, the paper examines current European Union policy frameworks on digital safety, particularly industry responses to the call for a more trusted Internet environment for children, and argues that technical solutions to be effective need to carefully balance a number of competing objectives and to be sufficiently grounded in evidence of parental and child experience of the Internet. 相似文献

If the OECD??s Development Co-operation Report for 2009 is correct in its claim that ??The international aid effort now adds up to less than the sum of its parts??, then continued rapid growth in aid transfers is likely to contribute to further aid absorption problems, as well as institutional atrophy and deteriorating governance and corruption control among aid recipients. This article considers aid for good governance and anti-corruption, using Tanzania as an example. ??The supply side of aid?? sketches the bigger picture in which such aid is located, stressing collective action problems facing the aid industry in the current period of growth and diversification. ??The consequences of aid proliferation on corruption control in an aid-dependent state?? provides some empirics from Tanzania. ??Conclusions: whither ??corruption control????? draws some conclusions for the future of aid for governance and corruption control. A key message is that donor-driven governance and corruption control initiatives have failed to address the governance weaknesses that excessive and uncoordinated aid has helped to create. 相似文献

The purpose of this paper is to use criminological theories to explain chronic drunk driving. There is little criminological research explaining recidivist drunk driving with criminological theories. Instead, most researchers posit that repeat drunk driving is explained as a byproduct of substance abuse. Although substance abuse is likely correlated to chronic drunk driving, theoretical explanations need to go further to understand a broader set of social and psychological predictors. Factor analysis and linear regression techniques are used to estimate the relationship between items from two assessment instruments with a number of drunken driving offenses. The sample consists of nearly 3,500 individuals on probation and parole in a Southwestern state. The findings support our contention that criminological frameworks are helpful to understand chronic DUI. We found significant results for volatility, antisocial friends, teenage deviance, and negative views of the law, while controlling for age, gender, marital status, and race. DUIs are a serious problem for the criminal justice system and understanding the individual level correlates of repetitive DUI is crucial for policy development. Further, chronic DUI offers criminologists an opportunity to determine the ability of criminological theories to explain this type of behavior. 相似文献

Forensic fractographic features of bone reliably establish crack propagation in perimortem injuries. We investigated if similar fracture surface features characterize postmortem fractures. Experimentally induced peri- and postmortem fractures were used to assess if fractographic features vary as bone elasticity decreases during the postmortem interval (PMI). Thirty-seven unembalmed, defleshed human femoral shafts from males and females aged 33–81 years were fractured at varying PMIs with a drop test frame using a three-point bending setup and recorded with a high-speed camera. Vital statistics, cause of death, PMI length, temperature, humidity, collagen percentage, water loss, fracture energy, and fractography scores were recorded for each sample. Results showed that fractographic features associated with perimortem fractures were expressed in PMIs up to 40,600 accumulated degree hours (ADH), or 60 warm weather days. Hackle was the most consistently expressed feature, occurring in all fractures regardless of ADH. The most variable characteristics were wake features (78.4%) and arrest ridges (70.3%). Collagen percentage did not correlate strongly with ADH (r = −0.04, p = 0.81); however, there was a strong significant correlation between ADH and water loss (r = 0.74, p < 0.001). Multinomial logistic regression showed no association between fractographic feature expression and ADH or collagen percentage. In conclusion, forensic fractographic features reliably determine initiation and directionality of crack propagation in experimentally induced PMIs up to 40,600 ADH, demonstrating the utility of this method into the recent postmortem interval. This expression of reliable fractographic features throughout the early PMI intimates these characteristics may not be useful standalone features for discerning peri- versus postmortem fractures. 相似文献

ABSTRACTProving that legislative committees really matter is not simple. The assembled papers aim to demonstrate fruitful paths to analysing when committees influence policy, what they can and should do, and how to detect their importance to the political process. 相似文献

AbstractThis article discusses what it means to “contribute” to waste disposal as that term is used in section 7002 of the Resource Conservation and Recovery Act. More specifically, the article examines whether the US Forest Service can violate section 7002 by not regulating hunting. Among the issues addressed are whether one can contribute to waste disposal passively, whether one can contribute to waste disposal without taking any action that addresses waste disposal and the extent to which the statutory term “contribute” is analogous to the common law concept of causation. 相似文献
