Interpretation And Understanding

To understand a term or other symbol, I argue that it is generally neither necessary nor sufficient to assign it a unique determinate reference. Independent of and prior to investigation, it is frequently indeterminate not only whether a sentence is true, but also what its truth conditions are. Nelson Goodman's discussions of likeness of meaning are deployed to explain how this can be so.     

Investigating Some Neglected Criteria: The Influence of Organizational Level and Perceived System Knowledge on Appraisal Reactions

Researchers have suggested that examining the factors which influence appraisal reactions is important because these reactions are critical criteria of appraisal effectiveness. The current field study investigates how organizational level and knowledge of the performance appraisal system may be related to employees' reactions toward the performance appraisal system. Inferences from past research suggest that supervisory employees' unique perspective on the appraisal system may lead to more positive evaluations. The present study attempts to better explain this relationship by investigating the effect of Perceived System Knowledge (PSK) as a mediator of this relationship. Results revealed that PSK completely mediated the relationship between organizational level and appraisal reactions.     

Revisiting Sartre on the question of religion

Jean-Paul Sartre's position on religion has traditionally been reduced to variations of his well-known atheism. This is a result of collapsing the distinction between religion and theism, as both critics and supporters of Sartre have commonly done. Consequently, attention to Sartre's persistent and pervasive concern with religious ideas, symbols, and experiences has been neglected. While the religious implications of Sartre's thought have mostly been considered in relation to Christian theology, other newer areas of religious studies suggest additional avenues for considering Sartre. Sartre's possible connections to four such areas are discussed: 1) Eastern religions; 2) Jewish studies; 3) feminist theology, and 4) the psychoanalysis of religion.     

Aspects of Young Children's Perceptions of Gender-Typed Occupations

Perceived competencies of men and women in gender-typed occupations, perceptions about how much money men and women earn in gender-typed occupations, and affective reactions regarding growing up to have gender-typed occupations were examined in 55 primarily White middle-class preschoolers and primary school children. Children (particularly boys) viewed men as more competent than women in masculine occupations, and rated women as more competent than men in feminine occupations. Children believed men earned more than women across occupations, but that men earned more money than women in masculine occupations, and women earned more money than men in feminine occupations. Children's affective reactions to growing up to have gender-role-consistent occupations were more positive than their reactions to having gender-role-inconsistent occupations. Results suggest children perceive differential competencies of men and women regarding gender-typed occupations, and differences in pay for men and women within gender-typed occupations, at ages younger than previously determined.     

Enrichment versus exercise effects on motor impairments following cortical removals in rats

Groups of rats were exposed to an enriched environment, given access to an activity wheel, or individually housed in wire mesh cages, impoverished. Rats were exposed in groups of four to the enriched environment or placed individually in the activity wheel for 2 h per day for 25 days preoperatively. Within each exposure group, rats sustained bilateral removals of sensorimotor cortex, or were sham-operated controls. Animals were trained preoperatively to locomote across a narrow elevated runway. Postoperatively, locomotor testing was initiated 17 days after surgery throughout which time all animals were maintained under impoverished conditions. Locomotor deficits following cortical damage were a function of preoperative exposure: enriched rats were least impaired; impoverished rats were most impaired. Rats allowed running wheel activity initially showed the same marked deficits as impoverished animals but recovered more rapidly. The opportunity for physical exercise afforded wheel animals preoperatively may have enhanced motor capabilities that aided recovery. However, physical activity alone did not yield the same protective effects from initial impairment as enrichment. Greater elaboration of neural structures associated with perceptual-motor enrichment probably accounted for the initial sparing of the enriched group.     

The Solution to the Surprise Exam Paradox

The Surprise Exam Paradox continues to perplex and torment despite the many solutions that have been offered. This paper proposes to end the intrigue once and for all by refuting one of the central pillars of the Surprise Exam Paradox, the “No Friday Argument,” which concludes that an exam given on the last day of the testing period cannot be a surprise. This refutation consists of three arguments, all of which are borrowed from the literature: the “Unprojectible Announcement Argument,” the “Wright & Sudbury Argument,” and the “Epistemic Blindspot Argument.” The reason that the Surprise Exam Paradox has persisted this long is not because any of these arguments is problematic. On the contrary, each of them is correct. The reason that it has persisted so long is because each argument is only part of the solution. The correct solution requires all three of them to be combined together. Once they are, we may see exactly why the No Friday Argument fails and therefore why we have a solution to the Surprise Exam Paradox that should stick.
