College Freshman Performance: Summer Entrants vs. Fall Entrants

Entering college students and their advisors—high school and college personnel—frequently assert that the student will do better academically by entering college during the summer term rather than during the fall term with its many extracurricular activities. Comparing the academic performances over the first two quarters of 320 summer quarter entrants with 320 fall quarter entrants at the University of Tennessee yielded no significant differences for season entered. The ACT composite score for each student was held constant by using analysis of covariance. Significant differences for year entered—1962 or 1963—were apparently a function of the lack of reliability in grading practices. The academic performance of entering students did not benefit from summer quarter entrance.     

Aiming at Truth: Doxastic vs. Epistemic Goals

Belief is generally thought to be the primary cognitive state representing the world as being a certain way, regulating our behavior and guiding us around the world. It is thus regarded as being constitutively linked with the truth of its content. This feature of belief has been famously captured in the thesis that believing is a purposive state aiming at truth. It has however proved to be notoriously difficult to explain what the thesis really involves. In this paper, I begin by critically examining a number of recent attempts to unpack the metaphor. I shall then proceed to highlight an error that seems to cripple most of these attempts. This involves the confusion between, what I call, doxastic and epistemic goals. Finally, having offered my own positive account of the aim-of-belief thesis, I shall underline its deflationary nature by distinguishing between aiming at truth and hitting that target (truth). I end by comparing the account with certain prominent inflationary theories of the nature of belief. I am grateful to Muhammed Legenhausen, David Velleman and an anonymous referee of this journal for helpful comments on earlier drafts of this paper.     

Safety Climate Measurement: an Empirical Test of Context-Specific vs. General Assessments

Purpose

Safety climate researchers develop and use both general and industry-specific safety climate measures. Theories about language comprehension suggest that context facilitates meaning; however, the relative value of context-specific safety climate measures in the prediction of safety outcomes is an empirical question that has not been rigorously tested. The purpose of the present study was to provide a rigorous comparison of context-specific vs. general safety climate measures.

Design/Methodology/Approach

Seven hundred forty-six university laboratory personnel from five different kinds of research labs (i.e., animal biological, biological, chemical, human subjects/computer, or mechanical/electrical) completed contextualized safety climate measures, a general safety climate measure, and measures of other safety-related constructs.

Findings

Measurement equivalence analyses indicated that the general safety climate measure was not equivalent across the five lab types. Hypothesis testing revealed that contextualized information was most helpful when included in safety climate measures for less, rather than more, safety-salient contexts, but overall, there was relatively little difference in the validities for general and context-specific measures.

Implications

Results suggest that context has a small influence on how individuals respond to safety climate measures and provide guidance for researchers/practitioners when deciding between using industry-specific or general safety climate measures. It appears most beneficial to use industry-specific measures when examining safety climate in a less-safety-salient context.

Originality/Value

This study offers one of the first empirical tests of a contextualized safety climate measure involving a rigorous, unconfounded comparison of five context-specific safety climate measures with a general measure.

     

The MOS Short-Form General Health Survey: single item vs multiple measures of health-related quality of life: some nuances.

Researchers concluded that Item 2 of the Short-form General Health Survey of the Medical Outcomes Study can be used as a single-item measure of health-related quality of life. This conclusion is tested again on a random sample of elderly people in the Netherlands. Although it can be concluded that the psychometric properties of the short form are satisfactory, the use of the single item as a measure of health-related quality of life is discussed.     

Staff programmer vs. system: The issues

Hiring a staff programmer who programs specific experiments makes the least demands on the user, but the laboratory throughput is limited. Developing a high-level user-programmed system permits high throughput, but entails considerable effort and certain risks. Details and examples illustrate the issues.     

Technology vs. science: The cognitive fallacy

There are fundamental differences between the explanation of scientific change and the explanation of technological change. The differences arise from fundamental differences between scientific and technological knowledge and basic disanalogies between technological advance and scientific progress. Given the influence of economic markets and industrial and institutional structures on the development of technology, it is more plausible to regard technological change as a continuous and incremental process, rather than as a process of Kuhnian crises and revolutions.     

Lay Understanding of Macroeconomic Causation: The Good-Begets-Good Heuristic

The functioning of the economic system is complex and technical. For its part, the public is constantly presented with information on economic causality. It is important for its members to assimilate this information, whether to further their personal goals or to engage advisedly in the democratic process. We presented economically untrained and trained participants with questions of the form: “If variable A increases, how will this affect variable B?” for all the combinations of 19 key economic indicators. Economically untrained participants were willing to commit themselves on most questions, despite their medium to low self‐report of understanding the concepts involved. Analysis of the pattern of responses reveals the use of a simple shortcut, the good‐begets‐good heuristic, which yields a sense of competence in the absence of understanding of the causal mechanism involved. Le fonctionnement du système économique est complexe et technique, et le public est constamment confrontéà des informations se référant à une causalitééconomique. Il est important que le public les assimile, que ce soit pout poursuivre ses buts personnels ou pour participer en connaissance de cause au processus démocratique. Nous avons présentéà des sujets, ayant bénéficié ou non d'une formation en économie, des questions sous la forme: “Si la variable A augmente, comment cela affectera‐t‐il la variable B?” pour toutes les combinaisons possibles de 19 indicateurs économiques clés. Les sujets sans formation économique sont disposés à prendre position sur la plupart des questions, malgré une auto‐évaluation assez basse quant à leur compréhension des concepts impliqués. L'analyse de la structure des réponses révèle l'utilisation d'un simple raccourci, l'heuristique “le bien engendre le bien”, ce qui leur donne un sentiment de compétence alors qu'ils ne comprennent pas le mécanisme causal en jeu.     

Activities and Causation: The Metaphysics and Epistemology of Mechanisms

This article deals with mechanisms conceived as composed of entities and activities. In response to many perplexities about the nature of activities, a number of arguments are developed concerning their epistemic and ontological status. Some questions concerning the relations between cause and causal explanation and mechanisms are also addressed.     

The Expansion of Epistemology: The Metaphysical vs. the Practical Approach

From the perspective of world philosophy, one phenomenon of the 20th century is quite intriguing. Certain philosophers in China as well as in the West, finding the traditional conception of epistemology too narrow-minded, argued that its scope should be expanded. The Chinese way of expanding epistemology might be called the metaphysical approach, and the Western way the practical approach. In this article, I will first give an outline of both approaches and then try to demonstrate that a substantial dialogue can be created between them. By focusing on the problem of the articulation of what we know, I will make the metaphysical approach and the practical approach engage each other and thus prove to be mutually complementary.     

Embarrassment: Actual vs. typical cases,classical vs. prototypical representations

Abstract

Theories of embarrassment were investigated by having subjects either recall an occasion when they were embarrassed or describe their idea of a typical instance of embarrassment. Subjects then rated their account on a questionnaire designed to measure five theoretical approaches to embarrassment: dramaturgic theory, social anxiety theory, and three decreased self-esteem theories. Patterns of means and of covariation for actual embarrassment best supported the dramaturgic theory. In contrast, subjects' accounts of typical embarrassment contained elements of all five theories. The written accounts were analysed to produce a prototype of embarrassment, which consisted mostly of elements of the dramaturgic and social anxiety theories. We propose that the concept of embarrassment is necessarily linked to dramaturgic difficulties, whereas it is contingently linked to social anxiety and decreased self-esteem.     

The Concurrentism of Thomas Aquinas: Divine Causation and Human Freedom

The paper deals with the problem of divine causation in relation to created agents in general and human rational agents in particular. Beyond creation and conservation, Aquinas specifies divine contribution to created agents’ operation as application in the role of the first cause and the operation of the principal cause employing an instrumental cause. It is especially the latter which is open to varying interpretation and which might be potentially threatening to human freedom. There are different readings of what it is for the secondary agent to “act through the power of the principal cause”. Either the divine cause causes only the existence of the effect of the secondary cause, or it also causes the cause to operate in the sense that it determines its outcome. The latter seems to contradict human freedom. Both readings of Aquinas were developed in the latter half of the sixteenth century within scholastic philosophy and theology.
