FINITE MODELS CONSTRUCTED FROM CANONICAL FORMULAS

This paper obtains the weak completeness and decidability results for standard systems of modal logic using models built from formulas themselves. This line of work began with Fine (Notre Dame J. Form. Log. 16:229–237, 1975). There are two ways in which our work advances on that paper: First, the definition of our models is mainly based on the relation Kozen and Parikh used in their proof of the completeness of PDL, see (Theor. Comp. Sci. 113–118, 1981). The point is to develop a general model-construction method based on this definition. We do this and thereby obtain the completeness of most of the standard modal systems, and in addition apply the method to some other systems of interest. None of the results use filtration, but in our final section we explore the connection.     

The suppression model remains unsound: A reply to Deutsch

In the present issue, we critically review the influentialsuppression model of the octave illusion (Chambers, Mattingley, & Moss, 2004). In a rejoinder to our article, Deutsch (2004b) defends the utility of the suppression model. Here, we respond to Deutsch’s arguments, many of which are based on criticisms of our recent experimental report (Chambers, Mattingley, & Moss, 2002). We argue that Deutsch’s criticisms of this previous investigation are unfounded and that her defense of the suppression model fails to account for the most important weaknesses of this theory. We conclude that the suppression model remains inadequate as an explanation of the octave illusion.     

Different paths to justice: the ADA, employment, and administrative enforcement by the EEOC and FEPAs

Under Title I of the ADA, individuals who believe they have been subjected to disability-based employment discrimination may file an administrative charge. This article looks at who files charges; over what issues, and with what outcomes in both Equal Employment Opportunity Commission (EEOC) field offices, and state and local fair employment practice agencies (FEPAs). The data for the article are computerized records of all ADA charges filed through March 31, 1998. The data indicate that individuals who rely on a FEPA to investigate their charge have a greater likelihood of obtaining a beneficial outcome than individuals who rely on the EEOC, but proportionately more individuals receiving a beneficial outcome are likely to receive monetary benefits from the EEOC than from a FEPA. Further, those who receive beneficial outcomes will probably receive greater monetary benefits from charges investigated by the EEOC than from those investigated by a FEPA.     

The Question of Questions: What is a Gene? Comments on Rolston and Griffths & Stotz

If the question “What is a gene?” proves to be worth asking it must be able to elicit an answer which both recognizes and address the reasons why the concept of the gene ever seemed to be something worth getting excited about in the first place as well analyzing and evaluating the latest develops in the molecular biology of DNA. Each of the preceding papers fails to do one of these and sufferrs the consequences. Where Rolston responds to the apparent failure of molecular biology to make good on the desideratum of the classical gene by veering off into fanciful talk about “cybernetic genes,” Griffiths and Stotz lose themselves in the molecular fine print and forget to ask themselves why “genes” should be of any special interst anyway.     

Attachment at early school age and developmental risk: examining family contexts and behavior problems of controlling-caregiving, controlling-punitive, and behaviorally disorganized children

Preschool to school-age trajectories of 242 children, including 37 with insecure-disorganized and 66 with insecure-organized attachment patterns, were examined. Child attachment and stressful life events (the latter retrospectively) were measured at ages 5-7, and mother-child interactive quality, parenting stress, marital satisfaction, and teacher-reported behavior problems were evaluated concurrently and 2 years earlier. Results indicated that all three disorganized subgroups had poorer mother-child interactive patterns and more difficult family climates than secure or insecure-organized children. The controlling-punitive group showed significant increases in maternal reports of child-related stress between preschool and school age. The controlling-caregiving group showed greater likelihood of loss of a close family member, and mothers of the insecure-other group reported lower marital satisfaction and greater likelihood of their own or a spouse's hospitalization. Controlling-punitive children had higher externalizing scores, and controlling-caregiving children higher internalizing scores, than secure children.     

Life Stages, Paradigms, and Patterns in the Twentieth Century

In response to John Wortley's article, Four-Stage Systems of Human Development, that appears in this issue, Stephanie Moss provides an overview of the theories that inform postmodern paradigms of aging. She demonstrates how in contrast to the rigidity of the ancient systems of aging that Wortley discusses, twentieth-century ideas provide flexible models that may be used to discuss the phenomenon of aging without imposing deterministic strictures. Through the yoking of feminist, Marxist, and psychoanalytical theories, Moss delivers a conceptualization of aging that begins to dissolve the binary oppositions that have permeated Western thought through the greater part of the twentieth century.     

Oral behavioral patterns in facial pain, headache and non-headache populations

Patterns of oral behavior have been suggested as factors leading to head and facial pain. The present study evaluated the frequency with which certain oral habits were self-reported by five groups of Ss: Facial Pain. Tension Headache, Migraine Headache, Combined Migraine and Tension Headache and No Pain. Four oral behavior patterns were found to be significantly different among groups. These were diurnal bruxism. thrusting the jaw forward, cupping the chin in the hand and resting the hand on the side of the face. When Ss were reclassified into those reporting no facial pain, temporomandibular joint (TMJ) pain, or a combination of TMJ and jaw muscle pain, the variables of diurnal bruxism and resting the hand on the side of the face were found to predict significantly both pain groups. However, the resting the hand factor was negatively weighted for the TMJ Pain group only. One other factor, nocturnal bruxism. was found to be self-reported at a significantly higher frequency in the Combined Facial Pain group compared to the No Facial Pain and TMJ Pain groups. Discussion focuses on the implications of the present findings on research in the facial pain and headache areas.     

Mapping racism

The author uses the metaphor of mapping to illuminate a structural feature of racist thought, locating the degraded object along vertical and horizontal axes. These axes establish coordinates of hierarchy and of distance. With the coordinates in place, racist thought begins to seem grounded in natural processes. The other's identity becomes consolidated, and parochialism results. The use of this kind of mapping is illustrated via two patient vignettes. The author presents Freud's (1905, 1927) views in relation to such a "mapping" process, as well as Adorno's (1951) and Baldwin's (1965). Finally, the author conceptualizes the crucial status of primitivity in the workings of racist thought.     

Power and Psychological Well-Being in Late Adolescent Romantic Relationships

Using Olsen and Cromwell's (1975) three facetsof interpersonal power (power in resources, process, andoutcomes), we examined the balance of power in lateadolescent romantic relationships and the associations between interpersonal power, adolescents'self-esteem, and depression. Participants were 61adolescent couples who were primarily European-American(90% of girls and 93% of boys), with the remainder being comprised of approximately 2-3% each of NativeAmerican, Asian, African American, and Hispanicindividuals. We assessed power in terms of access toemotional resources, control during video-tapedinteraction, and control over decision-making. Overall,couples were more likely to be described by themselvesand by independent observers as egalitarian, with themajority of couples equally contributing emotional resources, sharing power in interaction, andsharing decision-making responsibility. However,romantic relationships characterized by inequality inthe contribution of emotional resources and indecisionmaking were associated with greater psychologicalsymptomatology, especially for females.
