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。     

Impacts of urban renewal on the place identity of local residents – a case study of Sunwenxilu traditional commercial street in Zhongshan City,Guangdong Province,China

ABSTRACT

This paper studies the impacts of urban renewal on local residents’ place identity by examining the changes in local residents’ place identity in Sunwenxilu, a traditional commercial street in downtown Zhongshan City, Guangdong Province, China, which carried out urban renewal relatively early in modern China. Applying Breakwell’s [(2015). Risk: Social psychological perspectives. In J. D. Wright (Ed.), International encyclopedia of the social & behavioral sciences (2nd Ed.). New York, NY: Elsevier] identity process model and using the renewal process as a starting point, data concerning local residents’ place identity in Sunwenxilu were collected through in-depth interviews, observations, and literature analysis. The results reveal that local residents had established a strong place identity on Sunwenxilu before it changed to be a community of “incompetents” in the 1990s. In the late 1990s, Sunwenxilu was transformed into a cultural tourism pedestrian street. Right after the transformation, local residents regained their self-esteem with the improvement of the physical environment and intensification of cultural symbols, and re-established their place continuity by maintaining their collective memories. However, a failure to improve the local residents’ self-efficiency of place during the “superficial” renewal had resulted in vulnerability of the local residents’ place identity in terms of self-esteem, continuity and distinctiveness, thus causing another crisis of place identity. Obviously, the construction of place identity results from the interaction of all elements, so too much emphasis on only one element may trigger a new identity crisis.

A Segmentation of Volunteers at the 2013 Austin City Limits Music Festival: Insights and Future Directions

Volunteers at music festivals play a critical role in festival operation and success. As the music festival industry continues to grow, the ability for these large productions to effectively execute a large volunteer program is augmented. Volunteers from the 2013 Austin City Limits Music Festival were surveyed in regards to their self-image congruency, motivation, satisfaction, and intent to return as a volunteer at the festival. Analysis resulted in three distinct segments which has significant practical implications for festival management. Academic implications exist with the addition of self-image congruency and further discovery of volunteers in the festival and event industry.     

“Step into the Real Texas”: Associating and claiming state narrative in advertising and tourism brochures

Texas is one of the most popular states for tourists. Using quantitative and primarily qualitative methods, we analyzed how marketers of small cities and towns associate their place to four central components of the Texas state narrative – the flag, official and unofficial symbols, territory, and social–historical mythology – in advertising and tourism brochures in the years 2008–2010. We discovered that in parallel to the overuse of the “associating to well-known brand/narrative” strategy, marketers also invest efforts toward claiming the narrative. Thus our second goal was to discover which techniques were used in order to claim the state narrative. Using the state of Texas as an example may provide a test case for typology, associating and claiming state narratives in promotional materials.

北京跨界水源地生态可持续发展模式比较研究——以官厅水库流域延庆怀来两县为例

水资源短缺和水环境污染的现状使得北京跨界水源地发展模式受到各界的关注。以官厅水库流域的北京市延庆县和河北省怀来县为例,运用指标体系进行对比分析,得出了延庆县符合生态可持续的发展模式,其生态可持续发展水平也接近或达到相关标准;而相对而言,怀来县的发展模式和发展现状距离生态可持续的目标差距较大。而行政区划是导致北京跨界水源地境内外发展模式不同的重要原因。
