An extension of Holland's theory to its unnatural conclusion

Herein are recorded the events that led to the complete destruction of the United States in the late 1990's, beginning innocently enough in the 1960's with John Holland's Theory of Vocational Choice.     

An extension of assimilation theory to illusions of size,area, and direction

Two postulates, one concerning assimilation and the other concerning attentive fields, are employed to explain the Ponzo, Poggendorff, Wundt, and Hering illusions. Several new configurations are predicted from the theory. In addition, changes in the magnitude or direction of illusion which result from alterations of the basic illusion are explained.

Wives' work and psychological well-being: An extension of gove's social role theory of depression

The effectiveness of social role theory in explaining the relationship between wives' work (inside and outside the home) and psychological well-being is examined in reference to existing empirical patterns and alternative explanations. The theory is extended by the reorientation of its assumptions around central concepts and premises of the rational choice and social exchange framework: rewards, costs, cost reduction, alternative sources of gratification, and subjective evaluation of behavioral outcomes. Several mediating factors are integrated into the revised theory: help with housework and child care, work satisfaction, and participation in voluntary associations and social networks. The explanatory utility of the additional causal links proposed in the expanded theory is explored in a comparison of 50 employed wives and 50 housewives, all of whom have at least one preschool child living at home. The validity of the revised propositions is supported by the findings, which reveal no significant difference between the employed wives and the housewives in depression, health anxiety, or life satisfaction.     

A linear conservative extension of Zermelo-Fraenkel set theory

In this paper, we develop the system LZF of set theory with the unrestricted comprehension in full linear logic and show that LZF is a conservative extension of ZF^– i.e., the Zermelo-Fraenkel set theory without the axiom of regularity. We formulate LZF as a sequent calculus with abstraction terms and prove the partial cut-elimination theorem for it. The cut-elimination result ensures the subterm property for those formulas which contain only terms corresponding to sets in ZF^–. This implies that LZF is a conservative extension of ZF^– and therefore the former is consistent relative to the latter. Hiroakira Ono     

An extension of Wollenberg's redundancy analysis

An extension of Wollenberg's redundancy analysis is proposed to deriveY-variates corresponding to the optimalX-variates. These variates are maximally correlated with the givenX-variates, and depending upon the standardization chosen they also have certain properties of orthogonality.The author wants to acknowledge the benefit of several discussions on the topic of this article with Rick Bagozzi, as well as the constructive comments made by several anonymous reviewers. For assistance with the computer analysis, thanks are due to Bill Burrows and John Thorson.     

An extension of Anderson's solution for the latent structure equations

Anderson's solution for the latent structure equations is summarized and then extended in two ways so as to involve all items simultaneously.This article was written while the author was employed at The University of North Carolina.     

Anterior cingulate cortex and conflict detection: An update of theory and data

The dorsal anterior cingulate cortex (ACC) and associated regions of the medial frontal wall have often been hypothesized to play an important role in cognitive control. We have proposed that the ACC's specific role in cognitive control is to detect conflict between simultaneously active, competing representations and to engage the dorsolateral prefrontal cortex (DLPFC) to resolve such conflict. Here we review some of the evidence supporting this theory, from event-related potential (ERP) and fMRI studies. We focus on data obtained from interference tasks, such as the Stroop task, and review the evidence that trial-to-trial changes in control engagement can be understood as driven by conflict detection; the data suggest that levels of activation of the ACC and the DLPFC in such tasks do indeed reflect conflict and control, respectively. We also discuss some discrepant results in the literature that highlight the need for future research.     

A balance theory explanation of challenges confronting cross-sex friendships

This study was part of an ongoing investigation into four of the potential challenges confronting women and men in cross-sex fiendships (O’Meara, 1989). Unlike previous research, which explored the perspective of only one member of each cross-sex fnendship, this study examined the perspectives of both individuals in cross-sex fienhhips. The levels of actual and perceived agreement and understanding were investigated through utilization of a variation of Heiderian Balance Theory and Laing’s Interpersonal Perception Method. Seventy three pairs of cross-sex fiends completed a survey examining direct perspectives, metaperspectives, and meta-metaperspectives, on the four challenges. Over 92% of the participants were heterosexual, 68% were Caucasian, 10% were Afican American, 10% were Hispanic, 3% were Asian, 4% were Native American, and 5% indicated “other.” Results indicate that cross-sex fiends generally agree that O’Meara’s four challenges present only minimal problems in their individual relationships, and that balance theory provides a viable explanation of how perceived agreement and understanding concerning challenges are arrived at within cross-sex fnendships. Additionally, results illustrating disagreements and misunderstandings within cross-sex friendships highlight the importance of looking at the perspectives of both individuals within a dyad.     

An extension of construct validity for personality scales using twin-based criteria

A twin-based analysis of personality inventory scales yields information relevant to construct validity. If scales validly measure dimensions influenced developmentally either by environmental factors common to cotwins or by genetic similarities, these influences should be apparent in patterns of intraclass correlations and within-pair variance ratios for monozygotic and dizygotic pairs. Criteria for construct validity derived from adolescent twin statistics are illustrated with Wiggins' MMPI Content Scales. A type of discriminant validity indicates that some scales are not distinct in terms of the influences of familial similarity. Sex differences are examined.
