Using a national dataset of 820 women who had called the police for an incident of intimate partner violence, this study explored the relationship between several components of socioeconomic status (education, income, and employment), race, and the nature of interactions with police. Over and above the effects of control variables (the presence of an advocate on the scene, the severity of violence in the relationship, and prior calls to police), victims with higher education reported less positive interactions, less control during the interactions, and lower effectiveness of police. Race did not moderate these relationships, and the other components of socioeconomic status were not significantly related to any of the outcomes. Exploratory tests of mediation found that the relationship between education and the quality of interactions with police was explained by the fact that more educated victims felt they had less control in these incidents and were less likely to see the offender arrested. Results also provide evidence for the positive impact of advocates on interactions with police. Implications for research and policy are discussed.  相似文献

Based upon a functional approach to understanding aggression, we aimed to identify the occurrence of and to describe the features of three types of alcohol‐related violence defined a priori by ultimate goals: (1) violence in pursuit of nonsocial profit‐based goals, (2) violence in pursuit of social dominance goals, and (3) violence as defence in response to threat. A sample of 149 young men with offences of violence that were alcohol related was interviewed. Cases were classified and detailed information from the first ten cases in each class (N=30) was subjected to thematic analysis. Intoxicated violence in pursuit of nonsocial profit‐based goals was opportunistic and motivated by the desire for more alcohol or drugs. Violence, in these cases, although serious, appeared to be brief. Intoxicated violence in pursuit of social dominance goals was typically precipitated by past or current insult or injury, and was accompanied by strong anger and an adrenaline rush. Attacks were ferocious, and robbing the victim was not uncommon, perhaps to inflict additional humiliation. Feelings of pride and satisfaction were typical and expressions of remorse were uncommon. Regarding intoxicated violence as defence in response to threat, attacks were often expected, and in some cases the respondent made a pre‐emptive strike. Weapon use was common in this group. Fear was experienced, but so too was anger. Feelings of excitement were not reported and remorse was common. Further validation of these types is warranted, and the potential implications of these findings for prevention and treatment are discussed. Aggr.

This study explores the potential relationship of guns in students’ homes with attitudes indicative of tolerance of violence, negative attitudes toward women and their roles, and attitudes suggestive of myths regarding sexual assault. Seniors in Kentucky high schools whose families possessed guns (n = 1,749) produced higher scores on scales measuring these variables as well as on scales of relationship dependency and religious involvement than seniors whose families did not own guns (n = 912). Students whose families owned more than 10 guns tended to score highest on these measures compared with students whose families owned no guns or a few guns. Because of lower effect sizes, these significant associations require further investigation.  相似文献

Owing to their very high strength, nanocrystalline metals have been extensively studied over the recent years. The direct Hall–Petch law, empirically proportioning the material strength to the inverse square root of its grain size has been shown to break down below a grain size of the order of tenths of nanometers. This phenomenon has been widely rationalized as a gradual switch from intragrain mediated deformation mechanisms to grain boundary mediated deformation mechanisms. This transition has been observed in many finite element simulations, despite the intrinsic restriction of necessarily limiting the nanocrystalline representative assembly to only a few grains. Such a limitation is generally overlooked, and its influence on an uniaxial tension test – when compared to a complete sample of millions of grains – ignored. We propose here to quantify the approximation done by considering a finite number of grains by means of a simple analytical model based on the early work of Stevens [R.N. Stevens, Philos. Mag. 23 (1971) p. 265]. The finite element approximation is demonstrated to be relatively good, even down to only three grains in width, and a method to “correct” the stress-strain curves of small representative volumes is proposed.  相似文献

Wilhelm Dilthey is, famously, an epistemological pioneer for a second, ‘human’ kind of science that ‘understands’ life as we live it, instead of ‘explaining’ things as we observe them. Even today, he is usually cited for his role in the Erklären–Verstehen debate. My article, however, follows Heidegger's suggestion that we make the existence of the debate itself the problem. Whether there are different sorts of entity, different reasons for studying them and different means for doing so – such issues raise questions about science itself, not just about how to do it better. Moreover, what sort of philosopher is competent to address such questions? Heidegger argues that Dilthey's later writings intimate that it must be one who thinks from the ‘standpoint of (historical) life itself.’ This issue, says Heidegger, is ‘alive’ in Dilthey but is continually short-circuited by his very traditional plan for a ‘Critique of Historical Reason.’ Dilthey's unsuccessful struggles to produce this Critique are his gift to us, however. They encourage us to explicitly reconsider, as Heidegger does not only in Being and Time but throughout his life, what Dilthey cannot: If philosophy, like all human practices, is historical to the core, what is it to ‘be’ philosophical, about science or anything else?  相似文献

Nowadays, the criticism of the so-called ‘deficit model’ and the need for ‘upstream engagement’ in science and technology are becoming part of the master narratives of public policies in many countries, especially concerning nanotechnology. This may be considered as a major success for STS scholars, whose research results have largely contributed to this change, especially those concerning the GMO controversies. Some STS scholars thus move from a position of distant and critical observers to the role of experts in social engineering or advisers of policy-makers. However, in their enthusiasm concerning the expected benefits of upstream engagement, institutions, TA practitioners and social scientists seem to ignore some important limitations as well as the implicit framing assumptions of the concept. Based on an experience made by a group of social scientists in the Grenoble area—one of the major ‘nanodistricts’ in Europe—our paper shows that the ‘upstream engagement’ concept is still embedded in a linear model of innovation and is not very useful to anyone pursuing the co-production of innovations. It is especially true when socio-technical networks are already aligned by powerful actors and a worldwide agenda as in the case of nanotechnology. In order to give an opportunity for public engagement to have a larger impact on decision-making, we propose an alternative approach, which combines Actor–Network Theory (ANT), as an analytical tool, with the reflexive and ongoing implementation of public participation. Public engagement is probably one of the critical loci where STS scholars must reflect on the articulation between the knowledge they produce and public policies in action.  相似文献

We report on the specific interaction between DNA and some mica-family minerals and other layered silicate structures. The interaction depends on mineral surface's crystallography, chemistry and potential. These properties are responsible for a remarkable variety of adsorption mechanisms and can be used to modulate surface self-assembly and nanopatterning of DNA. The controlled deposition of DNA onto non-conductive mineral regions with atomically flat boundaries has very attractive applications in nano-biotechnology (for example, microelectronics, microarrays and sensors). In addition, the extreme affinity discovered for some mineral surfaces, together with their ability to organize the DNA molecules, could be an indication of their catalytic potential. It may also have had relevance in the prebiotic environment, with important implications for the earth and life sciences.  相似文献

Two experiments using the interference paradigm are reported. In the first experiment, the participants spoke aloud the names of celebrities and the names of objects when presented with pictures while hearing distractors. In the case of proper names, we replicated the data obtained by Izaute and Bonin (2001) using the interference paradigm with a proper name written naming task. In the case of common names, the results replicated those obtained by Shriefers, Meyer, and Levelt (1990). In the second experiment, the participants produced the names of celebrities when presented with their faces while hearing distractors that were either proper names associated with the celebrities (associate condition), that belonged to a different professional category (different condition), or that corresponded to the proper names of the celebrities (identical condition). For negative SOAs, “associate” distractors were found to increase latencies compared to the “different category” condition. The implications of the findings for proper name retrieval are briefly discussed.  相似文献

Four experiments were conducted to provide further support for a dual-process approach to conjunction errors in recognition memory over a single-process approach. In Experiments 1, 2a, and 2b study words were repeated once (2 presentations) or several times (8 or 16 presentations), and a response signal delay (RSD) was manipulated (short vs long). Short RSD groups produced lower hit rates but higher conjunction error rates compared to long RSD groups. Repetition effects on conjunction errors occurred for short RSD but not long RSD groups. In Experiment 3, additional judgements on new items were solicited to show that the “null” effects for long RSD groups in the earlier experiments were, in fact, illusory. Together, the experiments provide evidence for recollection-based rejections of conjunction lures and support a dual-process theory of recognition memory over a single-process model.  相似文献

Abstract

Critical social theories look critically at the ways in which particular social arrangements hinder human flourishing, with a view to bringing about social change for the better. In this they are guided by the idea of a good society in which the identified social impediments to human flourishing would once and for all have been removed. The question of how these guiding ideas of the good life can be justified as valid across socio‐cultural contexts and historical epochs is the most fundamental difficulty facing critical social theories today. This problem of justification, which can be traced back to certain key shifts in the modern Western social imaginary, calls on contemporary theories to negotiate the tensions between the idea of context‐transcendent validity and their own anti‐authoritarian impulses. Habermas makes an important contribution towards resolving the problem, but takes a number of wrong turnings.  相似文献
