癌症要告知实情吗？

面对癌症病人,应该不应该告知实情?这是临床医务人员常常面临的问题,目前尚无统一的标准。新的医疗事故处理条例规定、病人得知癌病的途径、临床治疗现状等方面分别论述告知癌症病人实情的理由。探讨了癌症告知策略:面对家属直言相告、面对病人通过交谈了解病人的性格特点、文化层次和情感类型,列举了不同类型的病人告知的方法。论述其告知病情后如何让病人走出误区,消除恐惧,把生存的压力转变成求生的动力,从而达到配合治疗,使病人敢于正视疾病,面对明天可能发生的任何事情。

多层螺旋CT在不同肝硬化分级评估中的应用

利用多层螺旋CT对不同肝功能分级的52例乙型肝炎后肝硬化患者、50例酒精性肝硬化患者及25例正常对照组受试者进行肝脏体积在体测量,并进行kappa检验和方差分析,结果显示多层螺旋CT在体肝脏体积测量具有很好的一致性及可重复性（P〈0．01）;乙型肝炎后肝硬化与酒精性肝硬化患者肝脏体积的总体变化趋势相同,都随着病情的进展逐渐缩小,Child-Pugh分级B级之间的乙肝后肝硬化与酒精性肝硬化组患者的肝脏体积差异达到统计学上显著性水平。

Data-driven Q-matrix validation using a residual-based statistic in cognitive diagnostic assessment

In a cognitive diagnostic assessment (CDA), attributes refer to fine-grained knowledge points or skills. The Q -matrix is a central component of CDA, which specifies the relationship between items and attributes. Oftentimes, attributes and Q -matrix are defined by subject-matter experts, and assumed to be appropriate without any misspecifications. However, this assumption does not always hold in real applications. To address this concern, this paper proposes a residual-based statistic for validating the Q -matrix. Its performance is evaluated in a simulation study and compared against that of an existing method proposed in Liu, Xu and Ying (2012, Applied Psychological Measurement, 36, 548). Simulation results indicate that the proposed method leads to a higher recovery rate of the Q -matrix and is computationally more efficient. The advantage in computational efficiency is particularly pronounced when the number of attributes measured by the test reaches five or more. Results also suggest that the two methods have different tendencies in estimating the attribute vector for each item. In cases where the methods fail to recover the correct Q -matrix, the method in Liu et al. (2012, Applied Psychological Measurement, 36, 548) tends to overestimate the number of attributes measured by the items, whereas our method does not show that bias.     

A psychologically based taxonomy of Magicians’ forcing Techniques: How magicians influence our choices,and how to use this to study psychological mechanisms

Magicians have developed a wide range of techniques to influence and control spectators’ choices of such things as card, word, or number. These techniques are what is called forcing. The present paper develops a psychologically-based taxonomy of forcing techniques with two goals in mind. Firstly, it should help uncover the different psychological mechanisms that underlie forcing techniques. Secondly, it should facilitate knowledge transfer between magicians and psychologists. The main division present two basic categories that can be used as a way of focussing separately on (1) decision-making processes and external influences on choices, and (2) links between sense of agency over action and outcome as well as the illusion of control over this outcome. This taxonomy allows us to clearly differentiate between forces in which there is or is not a free choice, and whether this choice has an impact on the following events.¹     

Financial and symbolic incentives promote ‘green’ charging choices

Electromobility can contribute to a reduction in greenhouse gas emissions if usage behavior is aligned with the increasing availability of renewable energy. To achieve this, smart navigation systems can be used to inform drivers of optimal charging times and locations. Yet, required flexibility may impart time penalties. We investigate the impact of financial and symbolic incentive schemes to counteract these additional costs. In a laboratory experiment with real-life time costs, we find that monetary and symbolic incentives are both effective in changing behavior towards ‘greener’ charging choices, while we find no significant statistical difference between them.     

Gender-Typed Behavioral Examples of Histrionic Personality Disorder

Findings that clinicians diagnose Histrionic Personality Disorder more frequently in women may be due to the feminine gender weighting of the criteria or because the diagnostic label elicits a feminine stereotype. Using a method derived from the act-frequency approach, undergraduates generated behavioral examples of the DSM-IIIR and DSM-IV Histrionic criteria without regard to sex or according to sex role instructions that elicited masculine or feminine sex roles. A national sample of psychologists and psychiatrists rated the representativeness of the symptoms for the Histrionic criteria or for Histrionic Personality Disorder. Feminine behaviors were rated more representative of Histrionic Personality Disorder and somewhat more representative of the Histrionic criteria than masculine behaviors suggesting that the feminine sex role is more strongly associated with the label than the criteria. Masculine behaviors were also rated less representative than sex-unspecified examples. Results provide a possible explanation for the higher rates of diagnosis of Histrionic Personality Disorder in women.
