A PCR-based heteroduplex assay was used to determine the presence and composition of Bacillus species in 11,059 Environmental Protection Agency PM2.5 aerosol samples from 11 U.S. cities. The assay differentiated three groups: Type A containing Bacillus anthracis and very closely related, often pathogenic, Bacillus cereus and Bacillus thuringiensis strains; Type B containing other B. cereus and B. thuringiensis strains; and a third group of more-distantly related Bacillus species. Eight of the 11 cities were positive for Bacillus species in 50% or more of the samples, and the percent of aerosol samples that contained the HD Type A group ranged from 3% to 32%. Cities from the eastern half of the United States generally contained a higher frequency and broader diversity of Bacillus species than the western half of the United States. Positive samples were detected throughout the year. These results have implications for pathogen detection in environmental samples, understanding the natural evolution of new pathogenic strains, and incidence of infection caused by strains of the B. cereus subgroup. 相似文献

Mediators, for the most part, describe their work as facilitation but what they actually mean varies considerably. Based on an exploratory study with nearly 90 mediators in Canada (all of whom are also mediation trainers), the author describes the great diversity among mediators' understanding of commonly-used terms like facilitation, transformative, settlement, and humanistic. She also reports on how such factors as context, gender, and number of years mediating affect mediator perceptions of what they do. In addition, the author shows how perceptions affect the overall philosophy and goal of the mediation practitioner. One implication of this research is that we can no longer presume to know what people mean by mediation, nor can we assume mediators are like-minded in how they understand their work. Thus, practitioners, scholars and policymakers are encouraged to be purposefully clear when describing and writing about the practice of mediation. 相似文献

Recent research and theory suggest narcissistic features contribute to aggression in adults. The present study examined the association of narcissistic features with aggression and internalizing symptoms in 233 students of 5th–8th grade at three inner-city schools. A factor analysis of the Narcissistic Personality Inventory in this sample revealed three factors: Adaptive Narcissism, Exploitativeness, and Exhibitionism. Regression analyses were used to predict the association of these three narcissistic features with self-, teacher-, and peer-reported aggression and self-reported internalizing symptoms. Results indicate narcissistic exploitativeness positively predicted self-reported proactive aggression, and narcissistic exhibitionism positively predicted internalizing symptoms. Narcissism and self-esteem interacted to predict teacher-reported aggression and self-reported internalizing symptoms. Results are discussed in the context of existing theories of narcissism, threatened egotism, and self-perception bias. 相似文献

This study examined the effects of judicial instructions on the outcome of a mock jury trial that involved a woman who pleaded self-defense after killing her abusive spouse. Jurors were instructed to adopt either an objective or a subjective standard of reasonableness when reaching a verdict. Within objective/subjective instruction conditions, half of the juries viewed a case in which the woman killed her abuser while he was attacking her (confrontational) and the remaining half viewed a case in which she killed him while he was asleep (no confrontation). Juries in the subjective conditions returned significantly more not guilty verdicts than jurors in the objective conditions. At the individual juror level, participants hearing subjective instructions were significantly more likely to rate the defendant as not guilty than jurors given objective instructions when the abuse was nonconfrontational. 相似文献

This article provides a broad overview of the necessity for and challenges of decolonising universities in South Africa. It situates the student protests for the decolonisation of knowledge within the debates on the African Higher Education landscape, the ideology of Pan-Africanism, and calls for an African Renaissance. The article highlights the context in which the Fallist Movement emerged in South Africa and the demands it articulated. This article questions whether or not the decolonisation of knowledge, and the broader university system, can truly materialise, given the inherent nature and functioning of these institutions and the current practices of decolonising universities. The article argues that to date the decolonisation of universities has largely been ad-hoc, performative, and technical, rather than the sustainable and substantive transformative processes that should be at the heart of any decolonisation project. Furthermore, the article asserts that the universities that we are trying to decolonise are rigged spaces as they have been fashioned in the image of western universities and align with their norms, values, and epistemologies. To break this foundational epistemological and cultural bedrock requires a complete overhaul of the structure, ideology, and functioning of the universities. Without major shifts in the power relations, orientation and forms of knowledge production at these universities, there can be no decolonisation. 相似文献

This study explores processes and policies that facilitate the development of community trails. With funding from Active Living Research and the research framework of the Physical Activity Policy Research Network (PAPRN), we conducted a multiple-site case study. A total of six trails in Hawaii, Massachusetts, Missouri, North Carolina, South Carolina, and Washington were chosen for study. The goals of this case study were to identify the policy influences on trail development, explore the roles of key players in trail development, and compare and contrast findings from the different trails. Trail development can be a long process. Some of the trails took over a decade to complete because of funding, opposition, and roadblocks in the form of design standard policies. Work in trail development requires a team of many players, and it is necessary to balance their varied motives to accomplish a shared overall goal. Foresight through the master planning process is also a vital component of successful trail development. Finally, community involvement is key. Communities contemplating trail development should explore the effects of policy on the trail projects reported here to proactively identify potential influence. 相似文献

In this research, we investigated the relations among system justification, religiosity, and subjective well-being in a sample of nationally representative low-income respondents in the United States. We hypothesized that ideological endorsement of the status quo would be associated with certain existential and other psychological benefits, but these would not necessarily be evenly distributed across racial groups. Results revealed that religiosity was positively associated with subjective well-being in general, but the relationship between system justification and well-being varied considerably as a function of racial group membership. For low-income European Americans, stronger endorsement of system justification as an ideology was associated with increased positive affect, decreased negative affect, and a wide range of existential benefits, including life satisfaction and a subjective sense of security, meaning, and mastery. These findings are consistent with the notion that system justification satisfies psychological needs for personal control and serves a palliative function for its adherents. However, many of these effects were considerably weakened or even reversed for African American respondents. Thus, the psychological benefits associated with religiosity existed for both racial groups, whereas the benefits of system justification were distributed unequally across racial groups. 相似文献

Many scholars lament citizens’ lack of political sophistication, while others emphasize that information shortcuts can substitute
for sophistication and help citizens with their political choices. In this paper, I use experiments to assess whether and
under what conditions institutions can substitute for sophistication and enable even unsophisticated citizens to make informed
decisions. The results of my experiments demonstrate that institutions, such as a penalty for lying or a threat of verification,
can help both sophisticated and unsophisticated citizens to make more informed decisions. Further, my results suggest that
institutions may, under certain conditions, level the playing field between sophisticated and unsophisticated citizens.
