Supervisors as SMEs: The Relationship Between Supervisor Job Experience and Ratings of Subordinate Skill Importance

This study investigated the relationship between supervisor job experience and ratings of the importance of eight skill components for performing subordinates' jobs. When examining these correlations, statistical control was utilized to ensure that supervisor and subordinate characteristics confounded with supervisor job experience were not affecting hypothesized relationships. As predicted, there were statistically significant positive correlations between supervisor job experience and ratings on 6 of the 8 components. Also as predicted, controlling for the characteristics confounded with supervisor job experience made a substantial difference in results; 13 of the 16 correlations using statistical control significantly differed from correlations that did not. This illustrates that future research on SME characteristics should consider controlling variables confounded with the focal characteristic(s) under study in order to more thoroughly understand characteristic–rating relationships. Implications of these findings for research and practice are discussed and suggestions for future research are offered.     

Subsumption and Relative Identity

This paper is a modification of Nicola Guarino and Christopher Welty's conception of the subsumption relation. Guarino and Welty require that that whether one property may subsume the other should depend on the modal metaproperties of those properties. I argue that the part of their account that concerns the metaproperty carrying a criterion of identity is essentially flawed. Subsequently, I propose to constrain the subsumption relation not, as Guarino and Welty require, by means of incompatible criteria of absolute identity but by means of incompatible criteria of relative identity. After discussing the benefits of applying relative identity in ontological investigations I provide a formal framework in which to prove a counterpart of the identity criteria constraint.This revised version was published online in October 2005 with corrections to the Cover Date.     

G.A.T.S. and universities: Implications for research

The likely impact of applying the General Agreement on Trade in Services (GATS) to higher education are examined. GATS aims to “open up” services to competition: no preference can be shown to national or government providers. The consequences for teaching are likely to be that private companies, with degree-awarding powers, would be eligible for the same subsidies as public providers. Appealing to the inadequate recently introduced “benchmark” statements as proof of quality, they would provide a “bare bones” service at lower cost. Public subsidies would go: education being reduced to that minimum which could be packaged in terms of verifiable “learning outcomes”. The loss of “higher” aspirations, such education of critically-minded citizens of a democratic and civilised society would impoverish the university’s research culture which demands honesty and openness to public scrutiny. Most university research is substantially supported by public subsidy. Under GATS discipline, commercial providers of research services could be entitled to similar public subsidies. Publicly funded fundamental research would fade, leaving university research totally dependent for funds upon the good will of industry and commerce. Present problems, such as the suppression of unwelcome results and the use of questionable results to manipulate public opinion, would considerably increase. The public would lose a prime source of trustworthy knowledge, needed in political discourse, legal disputation, consumer protection and in many other contexts.     

On relative universality and Q-universality

Adams and Dziobiak proved that any finite-to-finite universal quasivariety must be Q-universal, and then asked whether a somewhat weaker hypothesis could lead to the same conclusion. We show that their original hypothesis cannot be weakened to its naturally extreme form.To Professor Ale Pultr on his 65th birthdayThe authors gratefully acknowledge the support of the NSERC of Canada, of the project LN00A056 of the Czech Ministry of Education, and also of the Grant Agency of Czech Republic under the grant 201/02/0148.Special issue of Studia Logica: Algebraic Theory of Quasivarieties Presented by M.

个体相对剥夺感问卷在大学生群体的信效度检验

翻译与修订个体相对剥夺感问卷(Personal Relative Deprivation Scale,PRDS),并在大学生群体中进行了信效度检验。探索性因子分析结果显示,原问卷中两个反向计分的项目在主因子载荷很低,删除这两个项目后的PRDS-3各项目鉴别力良好; 探索性因子分析和验证性因子分析均显示PRDS-3符合单维度结构; PRDS-3重测信度为0.89,在不同样本间的内部一致性系数为0.77-0.81; PRDS-3得分与相对剥夺感、经济相对剥夺感、焦虑、压力、抑郁、攻击性等效标具有中高程度的相关关系(r>0.4,p<0.01)。PRDS-3得分与社会比较倾向的能力维度显著相关(r=0.46,p<0.01),且能部分地中介能力社会比较倾向对物质主义和生活满意度的影响。综上,可以认为,中文版PRDS-3信效度指标良好,符合测量学要求,可作为相对剥夺感的评估工具。     

操作表征在被试操作效应中的调节作用：ERPs研究

本研究考察操作表征(operational representation)在被试操作效应中的调节作用。选取结构性/功能性操作表征短语各160个,分析再认判断中的脑电差异。结果表明,动作编码比语词编码诱发更显著的P1、N2pb和N400;在500~700ms时间窗,相比于语词编码,对结构性和功能性操作表征短语进行动作编码均可显著诱发了中央区更负的平均波幅;在700~900ms时间窗,仅对于结构性操作表征短语,动作编码比语词编码诱发了前额叶更正的平均波幅。研究为动作编码的语义反馈加工机制提供了数据支撑,也为动作信息再激活与动作表征观点的整合提供解释方向。     

Do we need visual subjects?

It is widely accepted within contemporary philosophy of perception that the content of visual states cannot be characterized simply as a list of represented features. This is because such characterization leads to the so-called ‘Many Properties’ problem, that is, it does not allow us to explain how the visual system is able to distinguish between scenes containing different arrangements of the same features. The usual solution to the Many Properties problem is to characterize some basic elements of content as subjects, to which features are attributed by a predication-like relation. In this paper, I reconsider this solution and claim that the Many Properties problem can be solved without postulating such subjects. What is more, I argue that an alternative approach has stronger justification given the empirical data concerning human vision.     

Enactivism and predictive processing: a non-representational view

This paper starts by considering an argument for thinking that predictive processing (PP) is representational. This argument suggests that the Kullback–Leibler (KL)-divergence provides an accessible measure of misrepresentation, and therefore, a measure of representational content in hierarchical Bayesian inference. The paper then argues that while the KL-divergence is a measure of information, it does not establish a sufficient measure of representational content. We argue that this follows from the fact that the KL-divergence is a measure of relative entropy, which can be shown to be the same as covariance (through a set of additional steps). It is well known that facts about covariance do not entail facts about representational content. So there is no reason to think that the KL-divergence is a measure of (mis-)representational content. This paper thus provides an enactive, non-representational account of Bayesian belief optimisation in hierarchical PP.     

The relative value of two options for pigeons depends on their context

It is well known that when humans are given a choice between two options, their preference is affected by the presence of a third. Generally, there is an increase in preference for the option closer to the third. We show that a shift in preference in the direction away from the third option can occur in animals. We gave pigeons a choice between A, reinforcement following 10 pecks and a 0.5‐s delay, and B, reinforcement following 5 pecks and a 1.5‐s delay. Once stable preferences were established, we introduced a third stimulus, less preferred than the other two: C, reinforcement following 20 pecks and a 0.5‐s delay or D, reinforcement following 5 pecks and a 4.5‐s delay. We found that pigeons presented with C showed an increased preference for B, whereas pigeons presented with D showed an increased preference for A. Our results were consistent with the similarity or attentional hypothesis, which suggests that the third option should interfere with the option more similar to it or would draw attention to the less preferred component of the third option and generalize to the option more similar to it. Possible accounts for the differences in outcomes are suggested.     

Is Philosophy All About the Meaning of Life?

This article defends a conception of philosophy popular outside the discipline but unpopular within it: that philosophy is unified by a concern with the meaning of life. First, it argues against exceptionalist theses according to which philosophy is unique among academic disciplines in not being united by a distinctive subject matter. It then presents a positive account, showing that the issue of the meaning of life is uniquely able to reveal unity between the practical and theoretical concerns of philosophy, while meeting a range of desiderata for a typical specification of subject matter. After showing how recent analytic work on “the meaning of life” has conflated the traditional question with issues of social meaningfulness, it offers an explanation of why the traditional question has become marginalised in philosophy. The reasons are not good, however, so it concludes that philosophy should embrace its popular image.
