Structural Universals And Formal Relations

I will consider Armstrong's problems in trying to account for structural universals,i.e., a kind of complex universal whose instantiation by particulars involves differentparts of those particulars instantiating several basic properties and relations, such asthe property of being a molecule of methane. I present and criticise Armstrong's mostrecent attempt to explain structural properties by means of the identification of universals with types of states of affairs and I state my own solution to the problem by appealing to formal relations holding between particulars.     

Subjective Situations and Logical Omniscience

The beliefs of the agents in a multi-agent system have been formally modelled in the last decades using doxastic logics. The possible worlds model and its associated Kripke semantics provide an intuitive semantics for these logics, but they commit us to model agents that are logically omniscient. We propose a way of avoiding this problem, using a new kind of entities called subjective situations. We define a new doxastic logic based on these entities and we show how the belief operators have some desirable properties, while avoiding logical omniscience. A comparison with two well-known proposals (Levesque's logic of explicit and implicit beliefs and Thijsse's hybrid sieve systems) is also provided.     

A Comparison of Fathers' and Mothers' Involvement in Childcare and Stimulation Behaviors During Free-Play with Their Infants at 9 and 15 Months

Fathers and mothers of 87 firstborn infants completed a parental responsibility questionnaire; recorded accessibility and direct interaction time in caregiving, play, and outings; and were videotaped in a free-play session with their infants at 9 and 15 months of age. Analyses compared fathers' and mothers' involvement and interactive behaviors, and examined age-of-infant and gender-of-infant effects. At both times, fathers reported being less accessible to their infants and spending less time in direct interaction with them than did mothers. During times when both parents were available to the infant, fathers were less likely to provide basic care, but spent an equivalent amount of time in play and outings. Fathers in dual-earner families spent less time in accessibility, caregiving, and outings, but they engaged in as much play as mothers. Responsibility for disciplining the infant was rated as being equally shared amongst parents. During play, parents did not differ in the amount of physical contact, conventional play, nonconventional play, and attempts to direct the infant's attention. However, fathers vocalized less and made fewer requests than mothers. Differences between paternal and maternal involvement in childcare and stimulation behaviors are discussed with respect to infant age and infant gender.     

Neuropsychological findings in two children diagnosed with hamartoses: evidence of a NLD phenotypic profile.

Hamartoses (HM) are defined as disorders involving nonneoplastic tissue overgrowth. Studies have examined the neuropsychological profiles of children with common HM, such as neurofibromatosis type 1. Limited information is known regarding neuropsychological profiles of rare HM such as Osteochondromatosis Syndrome (OS) and Klippel-Trenaunay Syndrome (KTS). The current investigation is, to our knowledge, the first attempt to define the cognitive phenotypes in two boys with OS and KTS. Results revealed significantly greater impairments involving sensorimotor and visuospatial skills, while verbal memory and language skills appeared relatively preserved. Significant neurobehavioral problems and marked social difficulties were evident. These findings suggest that these syndromes are on a Nonverbal Learning Disorder (NLD) continuum, with varying degrees of severity.     

Messages about sex in the workplace: A content analysis of primetime television

Because television has the potential to shape cultural beliefs about both sexual norms and appropriate workplace behavior, it seems important to examine TV’s portrayal of “sexual etiquette” in the workplace. In a content analysis of two episodes of every primetime comedy aired on all broadcast and cable networks during fall 2000, we coded every sexual remark and behavior made in a workplace scene. Across all networks, 85 percent of programs and one in four workplace interactions contained some type of sexual content. Overall, a viewer is likely to hear eleven sexual remarks and see two to three sexual behaviors in a workplace setting per hour; this jumps to twenty-three remarks and nine behaviors on cable networks. Sexual remarks were mostly explicit, made in an office setting, by White men, and were rarely (1.4%) about sexual harassment or discrimination. Although sexual content in the workplace was generally less common on broadcast than cable networks, a broadcast network (Fox) actually had the highest overall rate, with sexual content in 38 percent of workplace scenes. Given that research suggests that TV teaches youth about sexuality and cultivates sexual attitudes and beliefs consistent with televised portrayals, it is alarming that youth may learn from television that sex in the workplace is not only commonplace, but also to be tolerated and enjoyed.     

The Catholic Diocese: A Transversalized Institution

The Catholic Church is built, on the one hand, upon a hierarchical structure and vertical relationships, with stratified duties, centered around an organizational culture which is based on strict obedience to institutional directives and which has a monopoly on the administration of the goods and resources concerning salvation. On the other hand, since the Second Vatican Council, the Church has proposed to incorporate lay people into God's Kingdom, a development which represents an opening to the active participation of diverse groups and a redistribution of access to the goods of salvation. Analysts may take a position one way or the other regarding their definition of the Church, and some even state the existence of a dominant church and a people's church. In contrast to both these perspectives, this paper looks at a methodological and theoretical model for studying diversity within Catholic unity. The model is based on the concept of the 'transversalized institution' as it is applied to the way in which Guadalajara's diocese functions.     

Sample size, confidence, and contingency judgement.

According to statistical models, the acquisition function of contingency judgement is due to confidence increasing with sample size. According to associative models, the function reflects the accumulation of associative strength on which the judgement is based. Which view is right? Thirty university students assessed the relation between a fictitious medication and a symptom of skin discoloration in conditions that varied sample size (4, 6, 8 or 40 trials) and contingency (delta P = .20, .40, .60 or .80). Confidence was also collected. Contingency judgement was lower for smaller samples, while confidence level correlated inversely with sample size. This dissociation between contingency judgement and confidence contradicts the statistical perspective.     

Psychometric Properties and Norms of the Family Needs Scale

We studied 205 low-income families, using the Family Needs Scale (FNS). Factor analysis of the FNS data resulted on a 7-factor solution with high internal consistency within the various subscales. We provide normative scores based on the factor structure of the FNS. A total of 53 parents completed the FNS on two occasions with an average of four weeks between these two ratings. In general, the test-retest reliabilities were low to moderate. A total of 61 pairs of parents independently rated their families with the FNS. Again, agreement between raters was low to moderate. Several factors that may have detracted from better test-retest and interrater reliability were identified. Our data point to the need for more psychometric studies with the FNS.
