Perceived mastery climate,felt trust,and knowledge sharing

Interpersonal trust is associated with a range of adaptive outcomes, including knowledge sharing. However, to date, our knowledge of antecedents and consequences of employees feeling trusted by supervisors in organizations remains limited. On the basis of a multisource, multiwave field study among 956 employees from 5 Norwegian organizations, we examined the predictive roles of perceived mastery climate and employee felt trust for employees' knowledge sharing. Drawing on the achievement goal theory, we develop and test a model to demonstrate that when employees perceive a mastery climate, they are more likely to feel trusted by their supervisors at both the individual and group levels. Moreover, the relationship between employees' perceptions of a mastery climate and supervisor‐rated knowledge sharing is mediated by perceptions of being trusted by the supervisor. Theoretical contributions and practical implications of our findings are discussed.     

An assessment of safety climate,job satisfaction and turnover intention relationships using a national sample of workers from the USA

The association between safety climate, job satisfaction and turnover intention has not been thoroughly researched. This research is needed so that safety researchers and practitioners can begin to delineate the impact of safety on organizational and business outcomes. A path analysis was completed using data from a national sample of workers from the USA (n?=?1525). The overall fit of the model was excellent and analyses determined that both training and resource adequacy positively affected safety climate and job satisfaction. Safety climate also positively influenced job satisfaction. Both safety climate and job satisfaction were negatively associated with respondents’ turnover intention. In the study, the relationship between job satisfaction and turnover intention is reiterated in a sample of workers across many industries. This study is novel because it is one of the first studies to confirm that turnover intention is reduced with increased safety climate in a diverse sample of workers.     

Nature Articulations in Norwegian Advertising Discourse: A Depoliticized Discourse of Climate Change

This article deals with how nature is articulated in public discourse and more specifically how humans’ relationship to nature is constructed via such articulations. Based on critical cultural analyses of ads presented in a Norwegian context, the article claims articulations of nature serve to a depoliticization of nature, which silence social differences and reduce environmental politics to individual moral action. Several rhetorical patterns of particular relevance to the articulation of nature are discussed, pointing out how disparate, sometimes conflicting, understandings of nature are rhetorically configured and aligned in ways that benefit a global market economy. There is a discursive distancing of nature and everyday life, even as nature remains valorized and very much central to national identity. This constrains citizens’ political engagement and undermines understandings of how to govern nature.     

Shifting Baselines: Conveying Climate Change in Popular Music

Popular music is a generation-specific zeitgeist, while music affords otherwise unobtainable engagement with environmental themes. Despite being the most widespread form of music there is a paucity of scholarship on climate change vis-à-vis popular music. In turn, this article explores how popular music may provide a soundtrack that narrates the rapidity of contemporary biophysical change. Approaches of conveying versus communicating climate change in music are considered across a spectrum of musical forms, from contemporary and historical popular music to contemporary classical music and sound art. The article applies the framework of shifting baselines to music engaged with environmental change in order to formulate a closer relationship between objective and quantitative intergenerational biophysical change and subjective and qualitative socio-cultural change. To cease losing track of such inexorable degradation, the article speculates on future musical forms that may obviate such intergenerational myopia by conveying and/or communicating the unprecedented rapidity of biophysical change.     

Diversity of antibiotic resistance genes and encoding ribosomal protection proteins gene in livestock waste polluted environment

The rapid development and increase of antibiotic resistance are global phenomena resulting from the extensive use of antibiotics in human clinics and animal feeding operations. Antibiotics can promote the occurrence of antibiotic resistance genes (ARGs), which can be transferred horizontally to humans and animals through water and the food chain. In this study, the presence and abundance of ARGs in livestock waste was monitored by quantitative PCR. A diverse set of bacteria and tetracycline resistance genes encoding ribosomal protection proteins (RPPs) from three livestock farms and a river were analyzed through denaturing gradient gel electrophoresis (DGGE). The abundance of sul(I) was 10³ to 10⁵ orders of magnitude higher than that of sul(II). Among 11 tet-ARGs, the most abundant was tet(O). The results regarding bacterial diversity indicated that the presence of antibiotics might have an evident impact on bacterial diversity at every site, particularly at the investigated swine producer. The effect of livestock waste on the bacterial diversity of soil was stronger than that of water. Furthermore, a sequencing analysis showed that tet(M) exhibited two genotypes, while the other RPPs-encoding genes exhibited at least three genotypes. This study showed that various ARGs and RPPs-encoding genes are particularly widespread among livestock.     

1961—2008年新疆阿克苏地区降水、温度变化特征

利用阿克苏地区5个气象站1961—2008年的降水和温度资料,对近50 a来该地区气候变化及其趋势进行了分析。各气象站年降水量变化趋势基本一致,总体上都呈增加趋势。除库车县气象站年平均温度呈降低趋势外,其余呈上升趋势。总体上,阿克苏地区年降水量和年平均温度均呈上升趋势。     

建筑行业发展与低碳生活的推广探讨

低碳生活是一种自然地节约各种资源的习惯,是一种生活习惯。气候变化是本世纪最严重的全球问题之一,不断推进低碳生活是减少人类生活对气候影响的重要途径。低碳生活推广后,消费者对建筑的规划、环境影响以及节能等关注将增加,进而影响建筑行业的发展。在分析低碳生活对建筑影响的基础上,提出了包括人才培养、政策支持和扩大宣传的多级支持发展建议。     

气候变化对洪湖湿地的影响

气候变化影响着湿地生态系统。在全球气候变化的背景下,洪湖湿地区域气候也发生了明显变化。通过对洪湖周边4个站点1961~2004年的气象数据分析,从气象学和生态学的角度探讨了气候变化对洪湖湿地的影响。结果表明20世纪60年代以来,洪湖湿地区域气温有显著升高趋势,气温增加倾向率为0264℃/10 a;年降水量有微弱升高趋势,增加倾向率为49964 mm/10 a;降水量夏季和冬季有升高趋势,但是春季和秋季有减弱趋势。气候要素的综合变化使洪湖湿地区域湿润系数具有降低趋势。气候变化造成洪湖湿地面积萎缩、水位降低,同时造成了生物多样性降低和生物入侵,降水格局的变化改变了湿地水文状况,加剧了湿地的生态不稳定性。研究结果为湿地恢复重建和本区湿地生态安全提供了科学依据.     

上海霾气候数据序列重建及其时空特征

利用上海11个气象站点1960～2008年日均相对湿度、能见度以及天气现象资料,重建了上海近50a霾气候数据序列,并从时间和空间两个方面分析了上海霾日数的气候特征和变化规律。结果表明,上海霾气候数据序列重建值与报表记录值之间变化形态存在着较好的一致性,重建值较记录值偏高。1960～2008年,上海霾日数以9.7d/10a的线性趋势显著增加,2002年以后霾日数总体上呈减少趋势。上海多年平均霾日数以冬季最多而夏季最少。近50a,上海霾日数呈现出西南部最多-市区较多-东北和东南部最少的空间分布,霾日数的空间变化趋势则表现为西南部增加较多而东部增加较少。1981～2008年,上海霾日数在西部和南部都增加,东部则减少。
