汉英网络新闻标题中数量模糊语的分类研究

为了研究数量模糊语在网络新闻标题中的应用,在对新闻标题中的数量模糊限制语进行分类的基础上,对汉英两种网络新闻标题中的数量模糊限制语进行研究发现：由于网络新闻均具有时效性强、真实性、简明扼要等特点,汉英两种网络新闻标题在语义上具有可对译性及语用功能上具有相似之处;汉英新闻标题中的数量模糊语在结构、词序、使用词汇的丰富程度及频率上均有所不同。     

转换性使用与版权侵权边界研究——基于市场主义与功能主义分析视角

转换性使用理论在美国司法实践中的扩大适用模糊了版权这一专有权利的边界。从版权法功能主义与市场主义视角对“转换性使用理论”进行法律分析,可以刺破这一概念的朦胧面纱,更为清晰和客观地划定转换性使用行为与版权的边界。即在不存在市场失灵的情况下,由版权人与使用人进行私人缔约可以较好地解决知识产品的供给与需求问题。在存在市场失灵的情形下,有必要对其从市场（使用是竞争性抑或补充性的）与功能（使用是创造性抑或复制性的）两个视角考量,并以此探讨我国借鉴“转换性使用理论”的体系效应与制度收益。     

分贷统还合同的法律性质与违约风险化解

分贷统还合同为政府通过合约统一贴息实现了扶贫资金的公司化运作,有效地发挥财政扶贫资金的整体效益,但也产生了合同法律性质认定争议大、合同履行易受政策变化影响;户贷企用导致贷款用途和资金安全存在风险,公司分红还款系统性违约等弊端,如公司经营不善,贷款亏空,一旦出现系统性违约,不仅影响农村社会稳定和政府公信力,司法机关亦将面临纠纷批量涌入的现实问题。为趋利避害,分贷统还合同有必要在综合衡量扶贫目的、公司盈利及扶贫责任和银行资金安全的基础上,调整户贷企用政策,甄别债权类型,考虑违约的具体情势,从实操层面化解分贷统还合同违约风险。     

Methods for spatial and temporal land use and land cover assessment for urban ecosystems and application in the greater Baltimore-Chesapeake region

Understanding contemporary urban landscapes requires multiple sets of spatially and temporally compatible data that can integrate historical land use patterns and disturbances to land cover. This paper presents three principal methods: (1) core analysis; (2) historic mapping; and (3) gradient analysis, to link spatial and temporal data for urban ecosystems and applies their use in the Baltimore-Chesapeake region. Paleoecological evidence derived from the geochronology of sediment cores provides data on long-term as well as recent changes in vegetative land cover. This information, combined with contemporary vegetation maps, provides a baseline for conducting trend analyses to evaluate urbanization of the landscape. A 200-year historical land use database created from historical maps, census data, and remotely sensed data provides a spatial framework for investigating human impacts on the region. A geographic information system (GIS) integrates core analyses with historic data on land use change to yield a comprehensive land use and land cover framework and rates of change. These data resources establish the regional foundation for investigating the ecological components of an urban ecosystem. Urban-rural gradient analyses and patch analyses are proposed as the most appropriate methods for studying the urban ecosystem as they link ecological and social patterns and processes for varying degrees of urbanization.     

Tweeting about emergency: A semantic network analysis of government organizations’ social media messaging during Hurricane Harvey

While social media like Twitter have been increasingly adopted by public-sector organizations, it remains less explored as to how government and emergency management (EM) organizations use these platforms to communicate with the public in response to emerging natural disasters. Extending the Situational Crisis Communication Theory (SCCT) to the realm of social media, this study examines the emerging semantic networks from 67 government and EM organizations’ official tweets during Hurricane Harvey over a three-week period. It identifies how multiple crisis response strategies—including instructing information, adjusting information, and bolstering—are constituted of different issues, actions, and organizational actors before, during, and immediately after the disaster event. Results suggest that government agencies use the strategy of instructing information predominantly before and during the disaster, whereas adjusting information and bolstering strategies are utilized more during post-disaster recovery. The study offers theoretical and practical implications of using a semantic network approach to studying organizational crisis responses.     

Evaluating the effect of a campus-wide social norms marketing intervention on alcohol-use perceptions,consumption, and blackouts

Objective: To evaluate the effect of a campus-wide social norms marketing intervention on alcohol-use perceptions, consumption, and blackouts at a large, urban, public university. Participants: 4,172 college students (1,208 freshmen, 1,159 sophomores, 953 juniors, and 852 seniors) who completed surveys in Spring 2015 for the Spit for Science Study, a longitudinal study of students' substance use and emotional health. Methods: Participants were e-mailed an online survey that queried campaign readership, perception of peer alcohol use, alcohol consumption, frequency of consumption, and frequency of blackouts. Associations between variables were evaluated using path analysis. Results: We found that campaign readership was associated with more accurate perceptions of peer alcohol use, which, in turn, was associated with self-reported lower number of drinks per sitting and experiencing fewer blackouts. Conclusions: This evaluation supports the use of social norms marketing as a population-level intervention to correct alcohol-use misperceptions and reduce blackouts.     

中国大学生词汇学习中的词典使用情况调查及启示

以自行设计的词典使用过程模型为基础对北京一所高校的大学一年级学生在英语词汇学习中的词典使用情况进行了一次调查研究,并对部分受试者进行了跟踪访谈。研究表明,受试者在英语词典使用的三个阶段上有待改进,词典使用的指导训练应及早展开。根据调查中反映的问题,对大学英语教学中的词典使用指导与训练提出了建议。     

单用、叠用、连用——代词“如何”的语法、语义分析

“如何”在现代汉语中的使用率稍低一些。不过,它功能较多,能构成各种不同结构的句式。如“如何＋VP/AP”、“NP＋如何”、“无论/不管＋如何”、“V得＋如何”、“如何如何＋AP/VP”、“NP＋如何如何”、“VP＋如何如何”、“如何如何＋NP”等。论文从单用、叠用、连用角度归纳了“如何”的主要用法,并具体解释了它在不同语境下的具体意义。
