Cholesterol and squalene are fatty materials of latent fingermarks that can be utilized for dating methodologies and visualization techniques. Previous studies have suggested these compounds undergo degradation in fingermarks as a function of time (days) and light at ambient temperature. However, studies assessing how their composition changes at low and high temperatures over short periods of time (hours) have not been published previously. Here, we performed quantitative analysis of cholesterol and squalene in natural fingermark residue using PVDF membrane, after exposure to a range of temperatures (−20 to 100°C) for 4 and 8 h. We found that levels of both fatty materials remained constant at −20 to 60°C, but both showed significant reduction at 100°C, over short exposure times. These results indicate that cholesterol and squalene are detectable at −20 to 60°C, whereas at 100°C or higher, both are lost due to rapid thermal degradation. 相似文献
In the present studies, we aimed to show that the perceived procedural fairness of societal actors’ multicultural decisions promotes ethnic minority members’ societal identification. These enhanced identification levels, in turn, contribute to better psychological health and well-being. Firstly, a vignette study in a sample of African Americans explored the effect of procedural fairness climate on identification. The second and third studies used self-report questionnaires. Study 2 consisted of a sample of sojourners in a university context, Study 3 analyzed online data through an African American sample. The studies provided evidence for the effect of procedural fairness climate on increased societal identification, which in turn mediates the fairness effect on increased well-being and psychological health. Societal actors can use procedural fairness to increase well-being when making decisions that involve ethnic minorities.
Acculturation strategy, a varying combination of heritage and mainstream cultural orientations and one of the significant determinants of youth development, has been understudied with Asian American youth and particularly at a subgroup-specific level. This study used person-oriented latent profile analysis (LPA) to identify acculturation strategy subtypes among Filipino American and Korean American adolescents living in the Midwest. Associations between the subtypes and numerous correlates including demographics, family process and youth outcomes were also examined. Using large scale survey data (N?=?1580; 379 Filipino American youth and 377 parents, and 410 Korean American youth and 414 parents; MAGE of youth?=?15.01), the study found three acculturation subtypes for Filipino American youth: High Assimilation with Ethnic Identity, Integrated Bicultural with Strongest Ethnic Identity, and Modest Bicultural with Strong Ethnic Identity; and three acculturation subtypes for Korean American youth: Separation, Integrated Bicultural, and Modest Bicultural with Strong Ethnic Identity. Both Filipino American and Korean American youth exhibited immersion in the host culture while retaining a strong heritage identity. Although bicultural strategies appear most favorable, the results varied by gender and ethnicity, e.g., integrated bicultural Filipino Americans, comprised of more girls, might do well at school but were at risk of poor mental health. Korean American separation, comprised of more boys, demonstrated a small but significant risk in family process and substance use behaviors that merits in-depth examination. The findings deepen the understanding of heterogeneous acculturation strategies among Asian American youth and provide implications for future research. 相似文献
The increased use of information and communication technologies (ICTs) has triggered enormous innovation in the public sector and created positive public value at the managerial, delivery of services, and policy levels. However, these positive outcomes do not automatically accrue simply by adoption of ICTs as public leaders can fail to adopt relevant new ICTs, use them poorly, or use them in ways that actually diminish public value, which raises the question of the importance of e-leadership. This article examines e-leadership and innovation capacity at the individual public manager level and fills in some gaps about the practice and implementation of ICTs in the public sector. We explore eight research questions useful in theorizing about e-leadership, develop constructs of e-leadership, and describe the current development of e-leadership. By comparing e-leadership in two country settings (South Korea and the United States), we also overcome the limitations of the existing Western-oriented studies about innovations in the public sector. In addition to the growth of e-leadership use and requirements for a variety of competencies equivalent to, but separate from, traditional communication competences, we find that national cultures exert significant influence on the major constructs of e-leadership, which implies that an effective e-leadership strategy should consider cultural contexts seriously. 相似文献
In this paper, we examine whether the impact of negative advertising on citizens’ evaluations of candidates depends on the
gender of the candidates. Given common gender stereotypes, we expect negative campaigning aimed at women candidates will affect
citizens differently than negative campaigning against male candidates. The results of our study, derived from a survey experiment
conducted on a nationwide sample of more than 700 citizens, demonstrate that negative commercials are less effective at depressing
evaluations of woman candidates, compared to male candidates. The findings are consistent and strong, across a range of forces
that people use to assess competing candidates (i.e., affect and trait evaluations, people’s beliefs about issues, anticipated
vote choice). The tight control of the experimental design, including randomization of respondents into different conditions
that vary in only one way, demonstrates that the gender of the candidate influences people’s reactions to different types
of negative commercials.
Conscious policy and program support for the resettlement of refugees in regional and rural areas is a relatively recent trend in Australia. Resettlement is a complex process that hinges on the establishment of viable communities. This review suggests that its outcomes, especially for refugee communities, are potentially mixed. However, an appropriately resourced, well managed and well planned refugee resettlement program can potentially provide beneficial outcomes for refugees and host communities. This article draws on existing empirical data and contributions made at a VicHealth Roundtable in late 2007 to thematically explore the challenges facing rural and regional resettlement programs. Given that settlement is a dynamic process and the approaches to rural and regional settlement are evolving, this article provides 12 propositions for a more effective and integrated approach to policy and practice. 相似文献
Children of immigrants who do translations and who interpret for others using their heritage language and English are known
as language brokers. Although prior research suggests that children of immigrants’ perceptions of the language brokering experience
vary greatly—from feeling a sense of efficacy to feeling a sense of burden—what remains unanswered in the literature is identification
of the antecedents and processes that help to explain the varying psychological experience of language brokers. Using data
from a two-wave prospective longitudinal study of 256 Chinese American adolescents, the present study tested potential mechanisms
that may be responsible for adolescents’ perceptions of the language brokering experience as a sense or burden or sense of
efficacy. The results demonstrate that adolescents’ Chinese orientation sets in motion a family process that is linked to
variations in the perceptions of adolescents’ language brokering experience. Adolescents who are more Chinese oriented have
a stronger sense of familial obligation, and these adolescents are more likely to perceive that they matter to their parents.
Adolescents’ perceived sense of mattering to parents, in turn, is associated positively with a sense efficacy, and negatively
with a sense of burden as language brokers. Those adolescents who are less Chinese oriented have a weaker sense of familial
obligation, and these adolescents are more likely to feel a sense of alienation from their parents. Adolescents’ sense of
perceived alienation from parents, in turn, is associated with a sense of burden as language brokers. Implications for developing
interventions for children who act as language brokers for their parents are discussed.
The author proposes and employs the Avalanche Perspective in analysing the entry of women into the Korean judiciary from the
first pioneers in 1952 to the present. Starting from a general atmospheric warming trend towards women in postwar Korea, there
developed instability in the status quo, then a breakthrough that led to a cascade of women participating in the legal profession.
Although cultural resistance and political obstacles remained to be overcome, this quantitative expansion ultimately led to
a greater acceptance of women’s participation in the judicial arena. Significant judicial changes that furthered the causes
of women in contemporary Korea were coincident with women being members of the judiciary. The quantitative changes of the
past fifty-six years opened the possibility of qualitative progress for women in the Korean judiciary. The Avalanche Perspective
as applied to the judiciary in Korea, provides an understanding of the forces at work that have had a profound effect upon
the place of women in the new cultural and political reality of the Korean people.

Research on the health benefits and consequences of close relationships has suggested the linkage in daily emotions (i.e., coregulation) between close partners is an important relationship dynamic. While the coupling of daily emotions among family members (parent–child and marital dyads) has been widely documented, research examining emotional coregulation among ethnic minority youth during adolescence, a period marked by heightened emotion and risk for psychopathology, remains an important area in need of exploration. This study examined correlates of emotional coregulation in a sample of Mexican-origin adolescents (Mage?=?15.02, SD?=?.83) and their parents (Mage?=?41.93, SD?=?6.70). Dyads reported on daily levels of distress and happiness for 14 consecutive days across two waves of data collection a year apart (nwave1?=?428 dyads, nwave2?=?336 dyads). Dyads who reported getting along were more likely to coregulate their daily happiness. Importantly, coregulation of distress was only present in older adolescents who reported above average levels of internalizing symptoms. The results suggest coregulation of distress may shape or be shaped by poor mental health during the later years of adolescence, a time when youth may be establishing a degree of emotional autonomy from parents.
