Taxonomy of quantities

The adjectives “generic”, “subgeneric”, “specific”, and “individual” are proposed to be added to the term “quantity”, depending on the case, in order to diminish the ambiguity of this term and to classify the different types of quantities.

Applying user analytics to uses and effects of social media in China

ABSTRACT

We introduce what user analytics can do in the first half of the paper and then illustrate how to do user analytics in the second half. In the current context, user analytics refers to a set of diverse communication research methods on uses and effects of social media. User analytics has evolved from TV ratings research to online user research. The history illustrates what data sources, measures, and analyses can be used for what types of research questions under user analytics. We discuss the similarities of and differences between user analytics and other methods of computational communication research (e.g. content mining and online experiments), and compare the strengths and weaknesses of user analytics with traditional quantitative methods (e.g. survey). Finally, we present an application study of Chinese bloggers to demonstrate how to employ user analytics methods to study the production, consumption, and effects of user-generated content.

The influence of childhood polyvictimization on disordered eating symptoms in emerging adulthood

Children who endure multiple victimization experiences, or “polyvictims," are vulnerable to maladaptive outcomes. Yet, little research exists evaluating the relationship between childhood polyvictimization and disordered eating symptoms (DES) in emerging adulthood. The current study examines the relationship between childhood polyvictimization and DES in emerging adults. Data were collected from 288 participants across two universities using online self-report measures. Hierarchical regression analyses revealed a significant positive relationship between number of childhood victimization experiences and DES in young adulthood (ß = 0.14; p = 0.016). Female participants were more likely to demonstrate DES (ß = 0.14; p = 0.008). Further, high levels of emotion dysregulation during young adulthood were associated with more DES (ß = 0.33; p < 0.001). Findings suggest that exposure to victimization experiences in childhood increases individuals’ risk for exhibiting DES in young adulthood. Results also highlight the strong relationship between individuals’ emotion regulation abilities and the presence of DES. Findings align with the theory that children who have endured high levels of victimization often feel overwhelmed by their emotions and circumstances, demonstrate emotion regulation difficulties, and may rely on maladaptive coping strategies, including disordered eating, to manage adversities. Study results emphasize the importance of considering victimization history when working with emerging adults displaying disordered eating symptomatology.

古汉语数量词用法考察

现代汉语中,数词无论是在表示物量还是表示动量时一般都需与量词连用。从汉语史的角度考察,古汉语中数量词用法比较复杂,在表数量上有一个由数词单用到数词、量词连用的过程;而且数(量)词的句法分布比较多样与现代汉语多有不同。本文主要考察古汉语中数量词的使用情况和在不同时期的用法现象,从而描绘出数量词的使用发展的演化脉络。     

论英语弱势语的语义语势缺省与话语交际媒介作用

与强势语相反,英语弱势语常常削弱语势,使意思含蓄,不明了,有意回避不愉快或换用柔宛的间接表达方式来达到发话人传达"弦外之音"的一种手段,英国民族文化造就的这种弱势语,虽然有些违背"话语合作原则"中"量的准则",但在话语交际中人们通过反面强调、委婉地拒绝或请求、制造幽默、传达柔美的意境等方式使用英语弱势语,极大地增进了彼此间的交往.     

关于非完整力学系统存在守恒量的数目

对非完整力学系统存在守恒量的数目进行了研究，研究表明，若力系统具有ｎ个广义坐标且受有ｇ个非完整约束，则此系统存在（２ｎ－ｇ）个函数独立的守恒量。文未讨论了Ａｐｐｅｌｌ０Ｈａｍｅｌ模型，并给出了它的一个新的守恒量。     

酶活力的量和单位的用法探讨
