This article reviews the application of metal-containing nanoparticles and nano-structured particles to fingermark detection. This area of research is attracting significant interest as advances in nanoscience are being incorporated into the field of forensic fingermark detection. Although more research is needed before some of the techniques presented can be implemented in routine casework, nanotechnology is likely to play a major role in the future to deliver more selective and more sensitive ways to detect and enhance fingermarks. 相似文献
Although the social status of women in Hong Kong has changed significantly in recent decades, Hong Kong women continue to perform mothering, caregiving and homemaking tasks into late adulthood. Employing an agential realist approach to analyse the homes and discursive–materialist practices of three older women, this paper explores how the entanglement of materialities, discourses and subjectivities at home as a site of cultural action contributes to the ongoing enactment of divergent subjectivities of older Hong Kong women. The structural–spatial configurations of the three homes manifest the patrilineal and male-dominated family system in Hong Kong, and such older women perform a set of ‘normal’ (house) wifely and motherly duties linked to the maintenance of the male-dominated family system. Nevertheless, these older women’s subjectivities and their domestic worlds evolve through ongoing discursive–materialist practices. This paper further argues that, even if such factors as materialities, structures and practices either are neutral or indeed reinforce existing power imbalances, the dynamic and ongoing intra-action of these factors results in exclusionary but open conditions that may stabilize or subvert social phenomena, such as the ones discussed in this study: patriarchal domestic practices in Hong Kong homes. 相似文献
Adolescent alcohol use is related to disinhibition traits and family environments. However, research is scarce on whether these factors predict alcohol use trajectories distally, from early adolescence into early adulthood. We examined whether sensation seeking and parenting environments in early adolescence predicted adolescents’ alcohol use trajectories proximally (middle-adolescence) and distally (early adulthood). Using four waves of data from 345 adolescents (51.3% female; 80% white) and their primary caregivers, we estimated adolescents’ alcohol use trajectories and examined variability in these by sensation seeking and parental control. The findings revealed distal, positive associations between sensation seeking and alcohol use; and negative, proximal associations between parental control and alcohol use. Also proximally, there was a significant interaction between sensation seeking and parental control. We discuss implications for theory and practice. 相似文献
This paper is a study of 127 firms participating in Korea's Technology Property Rights Concession Program, a program designed to stimulate technology transfer related to spin-off applications of public technology. The purpose is to identify the determinants of transfer success. The findings indicate that successful firms were motivated by the ability to access a core technology free of charge and to solve technical problems currently encountered in technology development. Second, the targeted technology was highly reliable. Third, interest in commercial success of the transfer was very high among the researchers involved in the transfer process and these researchers had a high degree of prior understanding about industrial problems on the part of participating firms. Relatedly, there was a very high satisfaction with the communication that existed between lab researchers and their industrial partners in the transfer process. Fourth, lab contributions to the transfer process were very high in the pre-commercial and commercial stages of technology development. 相似文献
Multiracial youth are thought to be more vulnerable to peer-related risk factors than are single-race youth. However, there have been surprisingly few well-designed studies on this topic. This study empirically investigated the extent to which multiracial youth are at higher risk for peer influenced problem behavior. Data are from a representative and longitudinal sample of youth from Washington State (N?=?1,760, mean age?=?14.13, 50.9% girls). Of those in the sample, 225 youth self-identified as multiracial (12.8%), 1,259 as White (71.5%), 152 as Latino (8.6%), and 124 as Asian American (7.1%). Results show that multiracial youth have higher rates of violence and alcohol use than Whites and more marijuana use than Asian Americans. Higher levels of socioeconomic disadvantage and single-parent family status partly explained the higher rates of problem behaviors among multiracial youth. Peer risk factors of substance-using or antisocial friends were higher for multiracial youth than Whites, even after socioeconomic variables were accounted for, demonstrating a higher rate of peer risks among multiracial youth. The number of substance-using friends was the most consistently significant correlate and predictor of problems and was highest among multiracial youth. However, interaction tests did not provide consistent evidence of a stronger influence of peer risks among multiracial youth. Findings underscore the importance of a differentiated understanding of vulnerability in order to better target prevention and intervention efforts as well as the need for further research that can help identify and explain the unique experiences and vulnerabilities of multiracial youth. 相似文献
In modifying general strain theory (GST), Agnew has accepted the control-related variables as conditioning variables to moderate or mediate the casual process through strain into delinquency. In this regard, this study aims to empirically and theoretically address the void of connecting traditional and redefined self-control variables to GST. To explore this issue, the current study employed data derived from the Korea Children and Youth Panel Study (KCYPS). Specifically, three waves (2012, 2013, and 2014) were used to test hypotheses from GST and control theories. Both trait-based low self-control and revised self-control partially mediated the relationship between strain and delinquency. However, only redefined self-control significantly interacted with strain in producing delinquency. The current research reveals the possible integration of redefined control theory and GST.
The discipline of International Relations (IR) in Australia, as elsewhere, is steeped in historical and ongoing violence, including violences of colonisation. The way that IR is taught and practised in Australia reproduces the discipline's erasures and ignorance of the effects of colonisation and ongoing forms of marginalisation, knowledge extraction, and harm that normalise existing structures of power. In this article, we ask how mainstream theories, pedagogies, and practices of IR scholarship in Australia contribute to the ongoing coloniality of the discipline and reproduce these geospatial hierarchies and structures of marginalisation and exclusion. We argue that, as teachers, we have to consistently engage in un-doing the violence of disciplinary history. We theorise that this is so because the artefacts we teach are the product of a knowledge life cycle immersed in, and structured by, coloniality and hierarchy. Drawing on a survey of Australian universities' IR curricula and interviews with their instructors, in addition to our own research training and practice as Australian IR academics, we examine how, if, and when it is possible to connect decolonial theory with practice and to thus generate decolonial praxis in the production of IR knowledge. 相似文献
