The Property Theory of Musical Works

The property theory of musical works says that each musical work is a property that is instantiated by its occurrences, that is, the work's performances and playings. The property theory provides ontological explanations very similar to those given by its popular cousin, the type/token theory of musical works, but it is both simpler and stronger. However, type/token theorists often dismiss the property theory. In this essay, I formulate a version of the property theory that identifies each type (thus, each musical work) with a unique property. I then scrutinize the arguments offered for thinking that types, including musical works, are distinct from properties. I respond that no such argument is forceful and conclude that the property theory of musical works is superior to the type/token theory.     

The dilution effect: judgmental bias,conversational convention,or a bit of both?

This study explored competing normative interpretations of the dilution effect: the tendency for people to underutilize diagnostic evidence in prediction tasks when that evidence is accompanied by irrelevant information. From the normative vantage point of the intuitive statistician, the dilution effect is a judgmental bias that arises from the representativeness heuristic (similarity-matching of causes and effects). From the normative prospective of the intuitive politician, however, the dilution effect is a rational response to evidence presented in a setting in which Gricean norms of conversation are assumed to hold. The current experiment factorially manipulated conversational norms, the degree to which diagnostic evidence was diluted by irrelevant evidence, and the accountability of subjects for their judgments. Accountable subjects demonstrated a robust dilution effect when conversational norms were explicitly primed as well as in the no-priming control condition, but no dilution when conversational norms were explicitly deactivated. Non-accountable subjects demonstrated the dilution effect across norm activation conditions, with the strongest effect under the activation of conversational norms. Although the results generally support the conversational-norm interpretation of dilution, the significant dilution effect among non-accountable subjects in the norm-deactivated condition is more consistent with the judgmental-bias interpretation.     

THE EVALUATION OF AN INTEGRATED APPROACH TO MEASURING ORGANIZATIONAL PRODUCTIVITY

This research describes a new approach to the measurement and enhancement of organizational productivity entitled the Productivity Measurement and Enhancement System (ProMES). Various conceptual issues regarding productivity are briefly reviewed and the system is described. Research is reported in which productivity measures using this approach were developed and evaluated in five organizational units. The measures from the system were then used to give group-level feedback, followed by group goal setting and group incentives. Results indicated that unit personnel were cooperative in developing and using the system and that the system had good psychometric characteristics. Feedback increased productivity 50%, and feedback with the addition of goal setting and incentives increased productivity 75% and 76%, respectively. The approach to measuring productivity has several unique features. For example, it combines all the functions of a unit into a single index of productivity that reflects     

Solutions to Infertility: Even the Simplest Medical Answer Raises Troubling Ethical Questions for Catholics

The purpose of this article is to consider the ethical issues surrounding the “simplest” case of in vitro fertilization from the author's interpretation of a Catholic perspective. (Editor's Note. Any references to Catholicism or Catholic perspective refer to the author's interpretation.)     

INTERACTIVE VIDEO ASSESSMENT OF CONFLICT RESOLUTION SKILLS

In this research we developed and validated an interactive video assessment of conflict resolution skills. A model of conflict management was used to develop the conflict scenarios and part of the scoring key. Computer assessments of conflict resolution skills and two cognitive abilities were administered to 347 supervisors and job performance ratings were collected from their managers. The conflict skills assessment was found to be significantly related to supervisory ratings of on-the-job performance in managing conflict but to be unrelated to the measures of cognitive ability. In addition, the conflict skills assessment had no adverse impact for women. The implications of these results and directions for future research are discussed.     

EMPLOYING CONJOINT ANALYSIS IN MAKING COMPENSATION DECISIONS

A method employing conjoint analysis that generates utility/cost ratios for various elements of the compensation package is described. Its superiority to simple preference surveys is examined relative to optimizing the level of employee satisfaction at any given expenditure level. Results of a study of the use of this method in fringe benefit planning in a large financial institution are reported.     

An Empirical Typology of Dyadic Formation

The background of and justification for empirical typologies are outlined. Various family typologies are discussed. Data from a random sample of 291 couples are subjected to a cluster analysis on the dyadic interaction, dyadic preference, dyadic stability, and identification as a pair by others of the couple. Seven types of dyadic formation were found: Uncommitted; Structurally Isolated, Wife-Supported; Self-Selected Committed; Structurally Committed; Vital; Unformed; and Wife-Removed. The types are shown to differ on value consensus and couple happiness, as well as on some background factors. The contribution of the work to theories of dyadic formation and family typologies is discussed.     

On the Explanatory Role of Correspondence Truth

An intuitive argument for scientific realism suggests that our successes in predicting and intervening would be inexplicable if the theories that generate them were not approximately true. This argument faces many objections, some of which are briefly addressed in this paper, and one of which is treated in more detail. The focal criticism alleges that appeals to success cannot deliver conclusions that parts of science are true in the sense of truth-as-correspondence that realists prefer. The paper responds to that criticism, in versions proposed by Michael Williams, Michael Levin, and, especially, Paul Horwich, by arguing that critics typically stop at a shallow level of psychological explanation. If we probe more deeply we discover a genuine explanatory role for correspondence truth.
