福鼎市桐江溪卤乙酸分布特征及潮汐影响分析

为了掌握福鼎市桐江溪卤乙酸(HAAs)的含量、时空分布规律及其来源,对水体中HAAs化合物进行取样调查。根据桐江溪水文情势及沿岸特点设置10个取样点,于2017年12月及2018年7月按照涨潮、退潮情况分别对水样进行采集,检测HAAs分布情况,同时将卤乙酸(HAAs)与水质特性、涨退潮进行了相关性分析。研究发现,HAAs是普遍存在于桐江溪中的污染物质。其中,一氯乙酸(MCAA)、二氯乙酸(DCAA)、三氯乙酸(TCAA)、一溴乙酸(MBAA)、二溴乙酸(DBAA)等5种卤乙酸(HAA_5)质量浓度为0.44～3.39μg/L;一氯乙酸(MCAA)、二氯乙酸(DCAA)、三氯乙酸(TCAA)、一溴乙酸(MBAA)、二溴乙酸(DBAA)、三溴乙酸(TBAA)、一溴一氯乙酸(BCAA)、一溴二氯乙酸(BDCAA)、二溴一氯乙酸(CBDAA)等9种卤乙酸(HAA_9)质量浓度为0.83～56.15μg/L。桐江溪中HAAs主要为DCAA,TCAA,TBAA 3种,其中DCAA为制药厂及医院排水导致,主要分布在下游;TCAA主要来源于河段上游的农业生产活动;TBAA为上游沸石矿尾矿库受雨水冲刷而流入的Br~-所生成,主要分布于河流中下段。相关性分析结果表明,温度与HAA_5,HAA_9质量浓度呈现正相关,pH值与HAA_5,HAA_9质量浓度呈现负相关;TCAA质量浓度于相同季节不同潮汐及不同季节相同潮汐时均呈现上游高于下游的现象,其他HAAs均不因涨潮、退潮的差异造成质量浓度分布的变化。掌握桐江溪HAAs的含量、时空分布规律及来源,探讨其与水质的相关性,对于净水工艺选择、水厂出水HAAs含量的溯源分析、水体环境风险评估以及研究水生生物体内HAAs的累积效应等有重要意义。     

PFIs involving multiple public partners: a case study from the Italian healthcare sector

The financial crisis experienced by many countries since 2008 has given new importance to private finance initiatives (PFIs) for providing public services. This paper analyses the relationships between multiple public and private sector actors participating in a PFI in the healthcare sector in order to better understand the motives and behaviour of public and private sector partners. High levels of trust and the active participation of a regulatory body were found to be significant factors in terms of creating a partnership that benefits all sides.     

Acting Intuition into Sense: How Film Crews Make Sense with Embodied Ways of Knowing

This study contributes to a holistic understanding of sensemaking by going beyond the mind–body dualism. To do so, we focus analytically on a phenomenon that operates at the nexus of mind and body: intuition. By observing four film crews, we unpack how people act their intuition into sense – that is, how they transform, through action, an initial sense (intuition) that is tacit, intimate, and complex into one that is publicly displayed, simpler, and ordered (i.e., a developed sense). Our model identifies two sensemaking trajectories, each of which involves several bodily actions (e.g., displaying feelings, working hands-on, speaking assertively). These actions enable intuition to express a facet of itself and acquire new properties. This study makes three important contributions. First, it develops the holistic-relational character of sensemaking by locating it in the relations among multiple loci (cognition, language, body, and materiality) rather than in each one disjunctively. Second, it theorizes embodied sensemaking as a transformative process entailing a rich repertoire of bodily actions. Third, it extends sensemaking research by attending to the physicality and materiality of language in embodied sensemaking.     

在买方市场条件下创造企业卖点研究

买方市场是指在供求关系中买方处于主动地位,成为主导方面的市场。我国买方市场具有初级性和结构性的特点。文章认为,我国在买方市场条件下仍然存在局部的卖方市场,企业需要在个性、文化、服务、技术和感觉诸方面来寻求自身“卖点”;应寻找新的市场机会,积极实行差异化策略,主动进行创新,抢抓机遇并充分利用消费断层创造企业卖点。     

补贴行为主体的认定:基于反补贴案例的国际比较

在反补贴调查中,对补贴行为主体"政府"和"公共机构"的界定是确定补贴利益是否存在的前提。由于多边规则缺乏可操作的明确规定,两者的认定主要体现在WTO成员方各自的国内立法和判例中。本文对美国、加拿大和欧盟立法和判例、WTO争端解决机构相关实践的分析表明,尽管主要成员认定标准的内容和适用略有差异,但内核基本一致、可操作性强,且为争端解决机构所采纳。鉴于此,除非WTO争端解决机构对"公共机构"作出新的解释,除非银行、土地和重要投入品部门的中国国有企业在股权多元化改革方面迈出新的实质性步伐,此类企业在国际反补贴争端中被认定为"公共机构"、其行为被视作"政府"行为的局面很难改观。     

Daily outfit satisfaction: the effects of self and others' evaluation on satisfaction with what I wear today

This study investigated the satisfaction of the outfit which an individual chose to wear for the day by examining how self and others' evaluations influenced the outfit satisfaction and the intention to re‐wear. In addition, moderator variables (body satisfaction and body surveillance) that affected the effect of the evaluative factors upon satisfaction and behavioural intention were also examined. An online‐survey was conducted and the sample size used in the analysis was 349 in total. Using SPSS 18.0 and AMOS 18.0, structural equation modeling analysis and one‐way analysis of variance were implemented for hypothesis testing. The results showed that self‐evaluation as a perception of appropriateness of the outfit for that day and others' positive feedback increases outfit satisfaction. Appropriateness perception also had a significant impact on the intention to re‐wear. However, feedback from others on one's outfit did not have a significant direct effect on behavioural intention. Three‐way ANOVA was performed to verify the impact the feedback from others, body satisfaction, and body surveillance had on the respondent's intention to re‐wear, and a three‐way interaction effect was statistically significant. While individuals with high body satisfaction were likely to be confident about their appearance overall, the feedback from others did not impact their satisfaction. Individuals with low body satisfaction were influenced by others' feedback on their outfit. Individuals with high levels of body surveillance who sensitively monitored others' feedback especially displayed decreased intention to re‐wear when feedback from others on their outfit was negative. This research contributed to the deeper understanding of consumer's clothing behaviour at the post‐purchase stage. Enhanced understanding of lasting satisfaction and benefits pursued throughout the time while using the product would be essential in developing consumer‐centric marketing strategies.
