图片信息丰裕度对消费者在线风险决策的影响

以图片标记信息丰裕度对消费者在线风险决策的影响为研究重点,引入详尽可能性模型(ELM),从购买行为发生之前的顾客关注度和购买之后的顾客满意度两个纬度,探索了消费者在线风险决策的影响因素。结果表明:信誉标记图片信息丰裕度中的评价方式种类和商家信用度、服务标记图片信息丰裕度中的保障服务以及商品促销标记,无论对消费者关注度还是消费者满意度均有显著的正向影响;支付服务图片信息丰裕度对消费者关注度影响不显著,但与消费者满意度有显著的正相关关系。另外,店铺动态评分、物流服务标记以及商品描述标记的图片信息丰裕度与消费者关注度及满意度相关性均不显著。研究结果为C2C交易平台以及网上卖家图片标记和信息展示提供了一定的理论指导。     

谈谈具体名词和抽象名词的双重性

英语中具体名词和抽象名词一般为不可数名词,但不是绝对的。本文试图通过大量例证说明有些具体名词和抽象名词具有可数与不可数名词的双重性,并指出实际运用与区别这种双重类别的重要性。     

认知视角下的程式语心理表征与译语词汇提取研究

程式语心理表征在认知加工过程中具有其独特的存储、提取优势,善加利用可以使翻译交际变得流畅、高效。“在线语法判断”和“在线词汇翻译”两项实验任务旨在研究程式语心理表征对译语词汇提取质量的影响。研究表明,高二语水平者程式语心理表征质量明显优于低二语水平者;程式语心理表征水平与译语词汇提取流利度、准确度呈正相关;不同类型的程式语表征对译语词汇提取质量具有不同的预测力。     

Speciation, its ecological and biogeographical consequences

I studied the effect of treehole (microhabitat) size distribution in local habitats on geographic difference in aquatic metazoan community structure by comparing differences between two sites on Iriomote Island, and between Iriomote Island (subtropical) and Tsushima Island (temperate), in southwestern Japan. In treeholes at each local site, the amount of litter, the species richness and total biomass of metazoa were positively correlated with treehole capacity. Between the two sites on Iriomote Island (Shirahama and Komi), the amount of litter, biomass and species number per treehole was greater at Komi where the mean and variance of treehole size were greater, while the dependencies of these parameters on treehole capacity were common to both sites. Total species number was larger at Komi (2 predators and 20 saprophages) than at Shirahama (1 predator and 19 saprophages). Most of the dominant taxa colonized larger treeholes with higher probabilities, although one taxa showed the opposite trend. Treeholes on Tsushima were smaller than those on Iriomote. The metazoan fauna in treeholes consisted of 15 saprophages on Tsushima, being less richer than that on Iriomote Island which had 2 predators and 21 saprophages. However, the dependencies of litter amount and biomass on treehole capacity did not differ significantly between the islands, although treeholes on Iriomote harbored a greater number of species per treehole than those on Tsushima. This study indicated that there are general correlates between community structure within individual treeholes (infracommunity structure) and treehole capacity (microhabitat size). Therefore, microhabitat-size distribution is potentially a significant constraint of local community structure, and its variation may contribute to the variation in local and regional species richness.     

Relationship between urbanization and bat community structure in national parks of the southeastern U.S.

Urbanization and development are predicted to increase considerably in the United States over the next several decades, and this is expected to result in large-scale habitat loss, fragmentation and loss of wildlife species. Thus, natural parks and preserves are becomingly increasingly important in the conservation of regional biodiversity. We used mist-nets and AnabatII acoustic detectors to survey bats in 10 national parks in the southeastern U.S. and examined the relationship between bat community structure and development in the surrounding 5 km. We predicted that species richness would increase with park size and that species richness and evenness would decrease with development. Species richness was not related to development or any other landscape characteristics including park size. In contrast, species evenness declined with increasing development. Percent Developed land in the surrounding 5 km area was the only variable that entered into the stepwise regression model. The decrease in species evenness in the urban parks was due to the dominance of big brown bats (Eptesicus fuscus) in these parks. The percentage of big brown bats in our captures was positively related to percent Developed land in the surrounding area. Our data suggest that urban parks may be important for conserving regional bat biodiversity. However, the low species evenness in these parks suggests that some bat species may be susceptible to the effects of urbanization and may be extirpated over time. Thus, management of urban as well as rural parks should strive to conserve as much bat roosting and foraging habitat as possible.

菲茨杰拉德创作能力的变迁——基于词汇测度的统计分析

传统上,不同评论者对同一作家作品的好恶往往会导致对作家创作能力截然不同的评价,这种主观定性评判并没有考虑作品本身的内在特质。计算语言学发现幂律分布在各类文本的词汇测度中具有普遍性,这为定量刻画文学作品的内在特质提供了统计手段。因为作家的创作能力不是一成不变的,不同创作时期的作品反映了作家创作能力的波动,为检验这一论断,以菲茨杰拉德的四部小说为例,对包括类符形符比、词汇增长率和词汇相对熵等在内的词汇测度进行统计分析,发现这三个测度与文中的形符数之间服从幂律关系。故提出一种计算作家创作能力的新测度以及比较其创作能力变化的新方法。菲茨杰拉德作品的实证分析表明：该测度不仅能够有力地印证现有的定性评论观点,而且还能够有效地反映作家创作能力的巅峰与低谷状态。     

英语歧义现象及其积极作用

歧义是一种语言形式能够表达两种或两种以上意义的语言现象，它普遍存在于世界各种语言中。一般认为歧义会有碍交流，但如果人们加以巧妙运用，却也能起到积极的作用，更好地达到某一交际目的。文章主要分析了几类英语歧义现象以及歧义在幽默笑话、广告、文学作品中的积极运用。
