Consciousness: a neurological perspective

Consciousness is a state so essentially entwined with human experience, yet so difficult to conceptually define and measure. In this article, we explore how a bidimensional model of consciousness involving both level of arousal and subjective awareness of the contents of consciousness can be used to differentiate a range of healthy and altered conscious states. These include the different sleep stages of healthy individuals and the altered states of consciousness associated with neurological conditions such as epilepsy, vegetative state and coma. In particular, we discuss how arousal and awareness are positively correlated in normal physiological states with the exception of REM sleep, while a disturbance in this relationship is characteristic of vegetative state, minimally conscious state, complex partial seizures and sleepwalking.     

Why do employees engage in counterproductive work behaviours? Cultural values and white-collar employees in China

This study examines the role of cultural values in influencing counterproductive work behaviours (CWBs). In particular, it focuses on the cultural values of power distance, long-term orientation and collectivism (both horizontal and vertical collectivism) as well as the Confucian values of guanxi and harmony. In line with recent approaches in moral psychology and sociology, we consider how Confucian values become moral triggers or inhibitors for employees to engage in CWB. In addition, we consider the moderating effects of guanxi and harmony on the relationships between the cultural values of power distance, long-term orientation, collectivism and CWB. The results from a survey of 489 white-collar employees in China confirmed the importance of cultural values in influencing CWB. Specifically, our findings indicate that guanxi moderates the relationship between cultural values and CWB and acts as a moral trigger for an employee to engage in CWB. With the exception of horizontal collectivism, we also found that harmony moderates the relationship between cultural values and CWB. Specifically, harmony acts as a moral inhibitor for an employee to engage in CWB. Lastly, we discuss the implications of the findings for theory and practice in the context of managing an increasingly global workplace and business environment.

     

Unpredictability and complexity of print-to-speech correspondences increase reliance on lexical processes: more evidence for the orthographic depth hypothesis

The Orthographic Depth Hypothesis [Katz, L., & Frost, R. (1992). The reading process is different for different orthographies: The orthographic depth hypothesis. In R. Frost & L. Katz (Eds.), Orthography, phonology, morphology, and meaning (pp. 67–84). Amsterdam: Elsevier Science] proposes cross-linguistic differences in the involvement of lexical processing during reading. In orthographies with complex, inconsistent, and/or incomplete sublexical correspondences, decoding is more difficult and therefore slower. This gives more time to the lexical route to retrieve information, and leads to a greater ratio of lexical processing. We test whether this mechanism applies both for words with inconsistent (in English) and for words with complex (in French) correspondences. As complex correspondences are sufficient to derive a correct pronunciation, an increase in lexical processing may not occur. In a reading-aloud task, we used the frequency effect to measure lexical processing. The data showed stronger involvement of lexical processing for inconsistent compared to consistent words, and for complex compared to simple words. The results confirm that Katz and Frost’s proposed mechanism applies to different sources of orthographic depth.     

Connections and Themes of Spirituality in Family Therapy

In this article, we provide an overview of current considerations of spirituality in family therapy literature and practice. We suggest that whatever practice of therapy is undertaken, implicity or explicitly it will reflect views on the connection between spirituality and family therapy--connections involving clients' and therapists' beliefs. A thematic framework based on dimensions of the instrumental and metaphysical is outlined. Clinical approaches and practices within these connections are discussed.     

Surreal decisions

Although expected utility theory has proven a fruitful and elegant theory in the finite realm, attempts to generalize it to infinite values have resulted in many paradoxes. In this paper, we argue that the use of John Conway's surreal numbers shall provide a firm mathematical foundation for transfinite decision theory. To that end, we prove a surreal representation theorem and show that our surreal decision theory respects dominance reasoning even in the case of infinite values. We then bring our theory to bear on one of the more venerable decision problems in the literature: Pascal's Wager. Analyzing the wager showcases our theory's virtues and advantages. To that end, we analyze two objections against the wager: Mixed Strategies and Many Gods. After formulating the two objections in the framework of surreal utilities and probabilities, our theory correctly predicts that (1) the pure Pascalian strategy beats all mixed strategies, and (2) what one should do in a Pascalian decision problem depends on what one's credence function is like. Our analysis therefore suggests that although Pascal's Wager is mathematically coherent, it does not deliver what it purports to, a rationally compelling argument that people should lead a religious life regardless of how confident they are in theism and its alternatives.     

Is Incompatibilism Intuitive?

Incompatibilists believe free will is impossible if determinism is true, and they often claim that this view is supported by ordinary intuitions. We challenge the claim that incompatibilism is intuitive to most laypersons and discuss the significance of this challenge to the free will debate. After explaining why incompatibilists should want their view to accord with pretheoretical intuitions, we suggest that determining whether incompatibilism is in fact intuitive calls for empirical testing. We then present the results of our studies, which put significant pressure on the claim that incompatibilism is intuitive. Finally, we consider and respond to several potential objections to our approach.     

制定诊疗规范--标准、指南和选择

制定一个诊疗规范,与对一个病人作出具体诊疗方案有相似性.在此两种情况中,人们必须鉴别可用的选择、评价不同选择的结果、确定这些结果是否合乎病人的意愿.诊疗规范可认定为一般的决定--是供给一组病人诊疗而不是一个病人诊疗的建议.
