Fractal Images of Formal Systems

Formal systems are standardly envisaged in terms of a grammar specifying well-formed formulae together with a set of axioms and rules. Derivations are ordered lists of formulae each of which is either an axiom or is generated from earlier items on the list by means of the rules of the system; the theorems of a formal system are simply those formulae for which there are derivations. Here we outline a set of alternative and explicitly visual ways of envisaging and analyzing at least simple formal systems using fractal patterns of infinite depth. Progressively deeper dimensions of such a fractal can be used to map increasingly complex wffs or increasingly complex value spaces, with tautologies, contradictions, and various forms of contingency coded in terms of color. This and related approaches, it turns out, offer not only visually immediate and geometrically intriguing representations of formal systems as a whole but also promising formal links (1) between standard systems and classical patterns in fractal geometry, (2) between quite different kinds of value spaces in classical and infinite-valued logics, and (3) between cellular automata and logic. It is hoped that pattern analysis of this kind may open possibilities for a geometrical approach to further questions within logic and metalogic.\looseness=-1     

Perfectionism and Suicide Ideation in Adolescent Psychiatric Patients

This study was conducted to examine the relations between dimensions of perfectionism and suicide ideation in an adolescent psychiatric sample. A sample of 66 adolescents from an inpatient psychiatric facility completed the Child and Adolescent Perfectionism Scale, the Child's Hopelessness Scale, and the Suicide Ideation Questionnaire. Overall, the results indicated that socially prescribed perfectionism was associated with greater suicide ideation and that it, along with hopelessness, accounted for unique variance in suicide ideation scores. The findings are discussed in terms of their practical and theoretical significance as well as their consistency with similar research with adults.     

The Patient Self-Determination Act and Advance Directives: Snapshots of Activities in a Tertiary Health Care Center

This study describes the results of a retrospective review of patients' charts who had an advanced directive (AD) and who were hospitalized in a tertiary, acute care teaching hospital. The purpose of the review was to understand from clinical, sociological, ethical and legal perspectives the nature and utility of ADs. Findings and implications of the review are discussed in terms of: patient demographics; diagnoses; quality of ADs; influence of ADs on clinical decisions; and legal aspects of ADs.     

Using a Person-Centered Approach in Community-Based Instruction for Adults with Developmental Disabilities

Instruction is a variable that has enhanced community access for adults with developmental disabilities. Community-based instruction emerged as an especially useful format to teach individuals daily living and work skills in the settings where skills would be used. As advocacy and self-advocacy for individuals with developmental disabilities increased, professionals recognized the importance of empowerment and self-determination in gaining community access. Adult education that incorporates the values of person-centered planning will evolve beyond what has traditionally been viewed as community-based instruction. This article describes the characteristics of community-based instruction designed to enhance not only community access, but also the participant's overall quality of life.     

Adaptiveness: A moderator of the adverse impact of hassles?

Adaptiveness constitutes coping consistently with Stressors so to reduce distress or, at worst, not aggravate it. Accordingly, it should moderate the adverse impact of hassles. Undergraduate volunteers (N = 200) responded to measures of hassles, adaptiveness, and the criteria of subjective distress, psychiatric symptomatology and minor physical ailments. In all three regression analyses, hassles made a substantial positive contribution and adaptiveness a small negative contribution to adverse outcome. The interaction between hassles and adaptiveness was non-significant in all three cases. Alternative interpretations were identified to guide further research.     

WHO CONSIDERS THEMSELVES VICTIMS OF DISCRIMINATION?

We focus on the general issue of how and why individuals might decide if they have been victims of gender discrimination and how social status differences between women and men may change the significance of experiencing gender discrimination. Because both self-protective and situational factors have been found to influence interpretation of prejudicial events, in the present study we explore several individual-difference factors that might differentially predict perceived gender discrimination in women and men. We found that, for men, low self-esteem and high personal assertiveness were related to higher ratings of personal discrimination. Low self-esteem was also related to men's perceptions of discrimination against men as a group. For women, high need for approval was negatively related to perceptions of personal discrimination whereas depression was positively related. Depression was also related to higher ratings of discrimination against women, as was feminism. We argue that perceptions of discrimination serve different purposes for structurally privileged and disadvantaged groups.     

The Balance of Power in Romantic Heterosexual Couples Over Time from “His” and “Her” Perspectives

In this investigation, the balance of power between men and women in romantic relationships was examined with a sample of 101 heterosexual couples, some of whom were surveyed up to jive times over a four-year period. A majority of the participants (who were primarily Caucasian and middle class) reported some imbalance in power in their relationship (53% of the men and 52% of the women on a global measure of power; 67% of the men and 65% of the women on a measure of decision making). The longitudinal data indicated that perceptions of power were quite stable over time. When power imbalances in relationships occurred, the male partner was more likely than the female to be seen as the power holder, although these differences were statistically significant only for men (full sample). In support of W. Waller's principle of least interest [(1937) The Family: A Dynamic Interpretation, New York: Gordon], being the less emotionally involved partner in the relationship was associated with greater power. We further found that men were more likely than women to perceive themselves as the less emotionally invested partner. Perceptions of power balance were generally unrelated to either relationship satisfaction or to the likelihood that the couple broke up over time. In one exception, men who perceived their relationship to be equal in power (but not decision making) reported the highest level of satisfaction. We conclude that the balance of power still often favors men in these romantic couples (especially in decision making), although couples do not always agree on their perceptions, with male partners tending to see more male dominance than females.     

Do college studentsstill prefer companies without employment drug testing?

Two experiments examined the effects of drug testing policies on undergraduates' behavioral intentions and attitudes toward the company. Study 1 (n=267) manipulated type of drug testing and consequences of detected use. Study 2 (n=267) manipulated the presence of applicant and employee drug testing. Subjects in both studies showed stronger intentions to apply to a company with random employee testing than one with no employee testing. Study 2 also found that an interaction between company policy and subjects' attitudes toward drug testing affected attitudes toward the company. Both studies suggest that employee drug testing may now foster recruitment.Study 1 was conducted while the author was at Ohio University and was presented in an earlier version at the Eastern Psychological Association's 64th Annual Meeting, Arlington, VA, April 16–April 18, 1993.I thank Candie Burbick and Jamie Winters for their work as student assistants.
