RESEARCH NOTE: Language with attitude: American slang and Chinese lǐyǔ1

The Mandarin registers known as lǐyǔ (俚语) have commonly been translated as ‘slang,’ though traditionally lǐyǔ has differed from slang in English by virtue of its strong link to regionalism. A newly emergent version of lǐyǔ that is prominent among young Chinese is marked not by regionalism but by its Internet‐enabled global purview. This youth‐culture lǐyǔ, like the student slang described by Eble (1996) , functions as a device to promote group solidarity while also serving as an identity marker for China's millennial generation. Lǐyǔ, like the numerous versions of slang described in English, Portuguese and other languages, is marked by ebullient or non‐deferential affect, an attribute that helps explains the close association between slang and swearwords. Slang and lǐyǔ lexemes, in light of the affect they entail, are the pragmatic opposites of honorifics – terms which index deference within formal, hierarchical structures.
     

油砂开发的环境风险

油砂是由砂、水和重而粘稠的碳氢化合物(常称之为沥青)等组成的一种混合物,可用于提炼石油.在过去的几年里由于传统石油供应量的减少以及油价暴涨使得石油公司开始关注油砂的开发利用.     

是垃圾还是财富?——让燃煤废弃物变废为宝

煤炭是否应该继续成为美国电力供应的主要来源,在这一问题上人们仍争论不休。美国能源信息管理局在《国际能源展望2009》一文中预测到,2006～2030年间,美国以及中国和印度的煤炭消耗量预计将净增加88%。与此同时,单就美国来看,燃煤废弃物——煤炭燃烧后的不可燃残渣——仍然以每年约1.31亿吨的速度在继续堆积,电力公司正在寻找回收这种残渣的方法。     

On the Contributions of Cognitive Sociology to the Sociological Study of Race

In this article, we argue for cognitive sociology as a framework for studying the sociology of race. Cognitive sociology concerns itself with classification, identity construction, meaning and collective memory and is thus centrally concerned with generic issues that apply well to racial category construction and maintenance. We, first, outline the cognitive sociology framework. We then elaborate on traditions in the sociology of race and racism that have implicit affinities to cognitive sociology. We argue that cognitive sociology provides a useful generic framework with which to look at specific issues in racial classification, the social construction of race, and to racist cognitions, while critical race theory and other sociology of race frameworks can compliment cognitive sociology by addressing issues of power and domination in cognitive frameworks.     

Why a Bayesian approach to safety analysis in pharmacovigilance is important

Large databases of routinely collected data are a valuable source of information for detecting potential associations between drugs and adverse events (AE). A pharmacovigilance system starts with a scan of these databases for potential signals of drug-AE associations that will subsequently be examined by experts to aid in regulatory decision-making. The signal generation process faces some key challenges: (1) an enormous volume of drug-AE combinations need to be tested (i.e. the problem of multiple testing); (2) the results are not in a format that allows the incorporation of accumulated experience and knowledge for future signal generation; and (3) the signal generation process ignores information captured from other processes in the pharmacovigilance system and does not allow feedback. Bayesian methods have been developed for signal generation in pharmacovigilance, although the full potential of these methods has not been realised. For instance, Bayesian hierarchical models will allow the incorporation of established medical and epidemiological knowledge into the priors for each drug-AE combination. Moreover, the outputs from this analysis can be incorporated into decision-making tools to help in signal validation and posterior actions to be taken by the regulators and companies. We discuss in this paper the apparent advantage of the Bayesian methods used in safety signal generation and the similarities and differences between the two widely used Bayesian methods. We will also propose the use of Bayesian hierarchical models to address the three key challenges and discuss the reasons why Bayesian methodology still have not been fully utilised in pharmacovigilance activities.     

Correction Constants for Present Values of Seasonal Cash Flows

In a recent Decision Sciences article, McMath (1990) developed the correction constants approach for eliminating the end-of-year bias in the present value of streams with subannual cash flows. A limitation of this approach is that it assumes subannual cash flows are level. In many types of businesses, subannual cash flows follow a predictable seasonal pattern and, consequently, a present value estimate based upon a level correction constant is biased. This article derives a general formula for determining correction constants for seasonal cash flow patterns, examines the direction and magnitude of the seasonal bias, and applies seasonal correction constants to a capital budgeting problem.     

The impact of ‘being assessed’ by a disabled children's team: a personal reflective account

The body of ‘service user’ literature confirms the value of parental perceptions of child and family social work and the insight parents and others can offer. This paper lends my voice to the literature regarding parental perceptions, inspired by the work of Pamela Davies, who provided a personal account of the impact of a child protection investigation. This paper draws upon my experiences of being a father of two ‘disabled children’ and undergoing an assessment of need. This paper seeks to draw attention to issues of choice, power imbalances and the role of expertise. My personal experience of undergoing an assessment was that it was an emotionally fraught process, for the duration of the assessment, our family stress increased and we had a sense of having to ‘battle’ for the support we needed. As such, my personal experience fits well with the wider body of literature, which highlights the increased stress of caring for children with additional needs, the challenges of ‘fitting’ disabled children into the frameworks used to assess all children and the difficulty for parents and professionals in distinguishing between ‘normal’ parenting responsibilities and the additional responsibilities of caring for a disabled child.     

Addressing common forms of child maltreatment: evidence‐informed interventions and gaps in current knowledge

This paper reviews interventions for preventing the occurrence and recurrence of major types of child maltreatment. We begin with an overview of the challenges of establishing evidence‐based interventions to prevent child abuse and neglect in many countries, and underscore the importance of this need with child maltreatment incidence rates in the USA, and how much each type and subtype contribute to child out‐of‐home placement. Next, we identify the well‐supported, supported and promising interventions for each child maltreatment type and subtype, according to their level of research evidence using an evidence‐based clearing house. The paper closes with a discussion of the implications for practice, evaluation, policy and agency management, including intervention knowledge gaps that showcase areas that need additional practice research.
