Simplified semantics for relevant logics (and some of their rivals)

This paper continues the work of Priest and Sylvan inSimplified Semantics for Basic Relevant Logics, a paper on the simplified semantics of relevant logics, such asB ⁺ andB. We show that the simplified semantics can also be used for a large number of extensions of the positive base logicB ⁺, and then add the dualising^* operator to model negation. This semantics is then used to give conservative extension results for Boolean negation.     

Genetic and Environmental Effects on Openness to Experience, Agreeableness, and Conscientiousness: An Adoption/Twin Study

ABSTRACT Previous research has indicated that extraversion and neuroticism are substantially affected both by genotype and environment. This study assesses genetic and environmental influences on the other three components of the five-factor model of personality: Openness to Experience, Agreeableness, and Conscientiousness. An abbreviated version of the NEO Personality Inventory (NEO-PI) was administered to 82 pairs of identical twins and 171 pairs of fraternal twins reared apart and 132 pairs of identical twins and 167 pairs of fraternal twins reared together. Estimates of genetic and environmental effects for Openness and Conscientiousness were similar to those found in other studies of personality: Genetic influence was substantial and there was little evidence of shared rearing environment. Results for Agreeableness were different: Genetic influence accounted for only 12% of the variance and shared rearing environment accounted for 21% of the variance. Few significant gender or age differences for genetic and environmental parameters were found in model-fitting analyses.     

New Careers Model Revisited: The Importance of Mentoring

The authors report a study that suggests the career paths of workers on short-term federal projects may be enhanced as a result of developing a relationship with a mentor through such projects.     

Morale and Job Satisfaction Among Nurses: What Can Hospitals Do?

In an attempt to account for morale and job satisfaction among 314 nurses, this study investigated the influence of work-related and interpersonal variables. Morale on the unit was directly related to supervisor support, co-worker relationships, and work recognition. Personal morale was accounted for by recognition, physical environment, the job itself, and pay. Job satisfaction was predicted by personal morale, work commitment, job clarity, work pressure, and innovation. Suggestions for improving nurse morale and job satisfaction are made.     

Small Wins: Perceptual Focus,Efficacy, and Cooperation in a Stage-Conjunctive Social Dilemma1

A multi-stage social dilemma was used to explore the notion that focusing on part rather than all of a complex problem would affect self-efficacy and action. In two experiments subjects considered a multi-stage game asking them to invest an initial sum of money in hopes of earning a larger bonus to be paid if provision points were met at all stages (a “stage-conjunctive” task). Results indicated that under most conditions considered, presentation of the whole problem encouraged cooperation. The opposite pattern occurred when group members were asked to complete very demanding stages first. We suggest that these results depend strongly on the stage-conjunctive nature of our task.     

Deviant logic and the paradoxes of self reference

The paradoxes of self reference have to be dealt with by anyone seeking to give a satisfactory account of the logic of truth, of properties, and even of sets of numbers. Unfortunately, there is no widespread agreement as to how to deal with these paradoxes. Some approaches block the paradoxical inferences by rejecting as invalid a move that classical logic counts as valid. In the recent literature, this deviant logic analysis of the paradoxes has been called into question.This disagreement motivates a re-examination of the philosophy of formal logic and the status of logical truths and rules. In this paper I do some of this work, and I show that this gives us the means to defend the deviant approaches against such criticisms. As a result I hope to show that these analyses of the paradoxes are worthy of more serious consideration than they have so far received.Letting a hundred flowers blossom and a hundred schools of thought contend is the policy for promoting the progress of the arts and the sciences.— Mao Tse-TungDedicated to Bob Meyer on the occasion of his 60th BirthdayThis paper was presented to the Department of Philosophy of the University of Queensland, and the 1992 Australasian Association of Philosophy Conference. I'm grateful for comments and criticism from those present; especially Graham Priest, Gary Malinas, Ian Hinckfuss, Mark Lance and Lloyd Reinhardt. The paper has a second half Comparing Deviant Logics that was read at the 1992 Australasian Association for Logic Conference, held in honour of Bob Meyer. Both are dedicated to him with appreciation for his work which, as many can see, provides inspiration for this conception of logic.     

SELF-REPORTED ASSERTIVE JOB-SEEKING BEHAVIORS OF MINIMALLY EDUCATED JOB HUNTERS

Little research attention has focused on the job-search behavior of minimally educated workers. The primary objective of the studies reported was to examine the relationship of self-reported assertive job-hunting behavior to acquisition of employment among minimally educated workers. The results of three studies provide: (a) construct validity evidence for the Assertive Job-Hunting Survey (AJHS; Becker, 1980), (b) evidence for construct similarity across minimally educated job seeker and college student populations, (c) evidence of a significant relationship between the AJHS and both subjective and objective job acquisition criteria in postdictive and predictive research designs, and (d) evidence that the AJHS, a measure of a non-cognitive variable, can make a unique contribution to the prediction of job acquisition beyond cognitive ability measures.
