Threshold decisions: how social workers prioritize referrals of child concern

This paper examines local authority social workers' decision‐making when considering referrals of children, where the concerns are on the margin of child protection procedures. In doing so, it describes the findings of a qualitative research study undertaken in the policy context of attempts to ‘refocus’ social work practice in the late 1990s and early twenty‐first century. Data collection involved interviews with social workers and parents in 23 cases. Conclusions are that referrals were evaluated on the basis of five key factors, specificity, severity, risk, parental accountability and corroboration, the use of which determined whether an initial assessment or an investigation of alleged abuse took place. The analysis builds on previous work in the child protection field, but demonstrates how the application of these factors differs between cases of child concern and cases of child protection. Policy implications concern the complexity of decision‐making in the uncertain context of limited referral information and it is proposed that the simplistic notion of a continuum of abuse is now outdated.

Physiologically Based Liver Modeling and Risk Assessment

Because of the inherent complexity of biological systems, there is often a choice between a number of apparently equally applicable physiologically based models to describe uptake and metabolism processes in toxicology or risk assessment. These models may fit the particular data sets of interest equally well, but may give quite different parameter estimates or predictions under different (extrapolated) conditions. Such competing models can be discriminated by a number of methods, including potential refutation by means of strategic experiments, and their ability to suitably incorporate all relevant physiological processes. For illustration, three currently used models for steady-state hepatic elimination--the venous equilibration model, the parallel tube model, and the distributed sinusoidal perfusion model--are reviewed and compared with particular reference to their application in the area of risk assessment. The ability of each of the models to describe and incorporate such physiological processes as protein binding, precursor-metabolite relations and hepatic zones of elimination, capillary recruitment, capillary heterogeneity, and intrahepatic shunting is discussed. Differences between the models in hepatic parameter estimation, extrapolation to different conditions, and interspecies scaling are discussed, and criteria for choosing one model over the others are presented. In this case, the distributed model provides the most general framework for describing physiological processes taking place in the liver, and has so far not been experimentally refuted, as have the other two models. These simpler models may, however, provide useful bounds on parameter estimates and on extrapolations and risk assessments.

Ranking Nuclear and Radiological Terrorism Scenarios: The Italian Case

A quantitative criterion for ranking the different scenarios of nuclear and radiological terrorism has been developed. The aim of the model is not to predict terroristic events but only to indicate which scenario has the higher utility from the point of view of a terroristic organization in terms of balance between factors favoring and discouraging the attack, respectively. All these factors were quantified according to a scoring system that takes into account the logarithmic relationship between perceptions and stimuli. The criterion was applied to several scenarios, each of which was modeled in a simple but not trivial way in order to estimate the expected damage in terms of probable life losses from both radiative and nonradiative effects. The outcome from the ranking method indicates that the attractive scenario appears to be the detonation of a low yield improvised nuclear device in the metropolitan area of a major city.     

对外文化教学中的主体意识略论

在一般的人类实践活动中,主体与客体的关系往往是主动与被动、决定与被决定的关系。但在对外文化教学实践活动中,由于教者与学者都是主体,原来的主体与客体之间的主动与被动、决定与被决定关系变成了第一主体与第二主体之间的平行互动、共生互决关系。在目前第二主体及其意识还未被关注的状况下,我们尤其要提倡以第二主体为中心的人本主义教育思想与教学方法,充分考虑和尊重作为第二主体即外籍学生的学习动机、感情倾向和价值观。

PSC朗读评分中的语音缺陷问题

在2002年12月《普通话水平测试大纲》修订工作征求意见稿中,我们发现它增加了对短文朗读中语音缺陷扣分的规定。短文朗读中的"语音缺陷"在《普通话水平测试大纲》现行评分标准中一直处于被忽视的地位。笔者同意征求意见稿的观点,对短文朗读中存在的"语音缺陷"应该扣分。短文朗读中存在的"语音缺陷"不能归入语音错误,也不能把它们划入"方言语调"的范围,应该把它们并入"方言色彩"的测试中。为此,笔者提出了短文朗读里语音缺陷的评分办法。
