Number of Extensions of Non-Fregean Logics

We show that there are continuum many different extensions of SCI (the basic theory of non-Fregean propositional logic) that lie below WF (the Fregean extension) and are closed under substitution. Moreover, continuum many of them are independent from WB (the Boolean extension), continuum many lie above WB and are independent from WH (the Boolean extension with only two values for the equality relation), and only countably many lie between WH and WF.     

Reference-frame misalignment and cardinal direction judgments: group differences and strategies

In 3 experiments, the authors examined how misalignment of egocentric and exocentric reference frames affects cardinal direction judgments. Experiments 1 and 2 demonstrated large differences in the accuracy and speed with which 104 less experienced and 7 experienced navigators made cardinal direction judgments. Reference-frame misalignment was associated with large performance decrements. The extent of these decrements diminished as ability and experience increased: however, even experienced navigators showed decrements when reference frames were misaligned. In Experiment 3, the authors used 55 college students to examine the individual subtasks of a common strategy for cardinal direction judgments and to isolate the effects of reference-frame misalignment to a particular subtask of this strategy. The tasks and strategies studied in this article can be applied in the development of navigational training and interfaces.     

Relation of Age of Onset to the Type and Severity of Child and Adolescent Conduct Problems

In a cross-sectional household sample of 9-through 17-year-old youths from 4 U.S. communities, youths with earlier ages of onset of conduct problems engaged in more conduct problems than youths with later ages of onset when current age and gender were controlled. Specifically, youths with earlier ages of onset were more likely to engage in several types of physical aggression, frequent lying, theft, and vandalism and were less likely to engage in only truancy. There also was an inverse relation between age of onset and level of functional impairment, mental health service use, and meeting diagnostic criteria for conduct disorder, attention-deficit hyperactivity disorder, and oppositional defiant disorder. Within the limits of cross-sectional data, these results support the hypothesis that key aspects of the heterogeneity of conduct problems among youths are related to the age of onset of conduct problems.     

“Nothing About Me, Without Me”: Participatory Action Research with Self-Help/Mutual Aid Organizations for Psychiatric Consumer/Survivors

Participatory action research with self-help/mutual aid organizations for psychiatric consumer/survivors is reviewed. We begin by tracing the origins of and defining both participatory action research and self-help/mutual aid. In so doing, the degree of correspondence between the assumptions/values of participatory action research and those of self-help/mutual aid for psychiatric consumer/survivors is examined. We argue that participatory action research and self-help/mutual aid share four values in common: (a) empowerment, (b) supportive relationships, (c) social change, and (d) learning as an ongoing process. Next, selected examples of participatory action research with psychiatric consumer/survivor-controlled self-help/mutual aid organizations which illustrate these shared values are provided. We conclude with recommendations of how the key values can be promoted in both the methodological and substantive aspects of future participatory action research with self-help/mutual aid organizations for psychiatric consumer/survivors.     

Child abuse and neglect reporting laws: Understanding interests,understanding policy

This article focuses on the interests of the persons involved in the child abuse and neglect reporting process—(1) the child, the accused, and the family members of the child and of the accused; (2) physicians, psychologists, therapists, private agency and hospital social workers, educators, and other professionals; (3) law enforcement officers, state social service workers, lawyers, and judges; and (4) legislators. With this focus, the article illuminates the rationales and explicit and implicit policy choices reflected in the legislation's reporting requirements and processes. Such insight is necessary to a critical review of existing legislation and future improvements in the practical operation of reporting law legislation. This article demonstrates that the interaction of these interests is complex and often creates competing concerns and goals. This article concludes that efforts should be made to better harmonize these interests in future legislation.     

Longitudinal changes in term and preterm infant night wakings: The role of caregiver anxious-depression

Changes in infant night waking during the first year of life are associated with individual (e.g., prematurity) and family (e.g., caregiver psychopathology) factors. This study examined the association between infant night waking and caregiver anxious-depressive symptoms during the first year of life in preterm and term infants. We considered between-person differences and within-person changes in caregiver anxious-depressive symptoms in relation to changes in infant night waking from 2- to 9-months. Racially (30.0% Black, 60.4% White, 9.5% multiracial/other) and socioeconomically (40.0% below median household income) diverse caregivers (N = 445) of full term (n = 258) and preterm (n = 187) infants were recruited from hospitals and clinics in two midwestern states. Caregivers completed measures of anxious-depression and their infant's night waking at four sampling periods (2-, 4-, 6-, and 9-months). Infant night wakings declined from 2- to 9-months. Between-person differences were observed, such that caregivers with higher average anxious-depressive symptoms or infants born full term reported more night wakings. Within-person effects of caregiver anxious-depressive symptoms were not significant. Caregiver anxious-depression is closely associated with infant night wakings. By considering a caregiver's average severity of anxious-depression, healthcare providers can more effectively plan infant sleep interventions. If caregiver anxious-depressive symptoms are ameliorated, night wakings may also decrease.     

The definition of sociology and the sociology of definition: Durkheim's Rules of Sociological Method and high school philosophy in France

Despite his attempts to break with philosophy and found a science of society, Émile Durkheim (1858–1917) was involved with philosophy throughout his career. Academic philosophy in France was a highly centralized institution that produced professors capable of teaching a standard curriculum. These professors made up a significant portion of the audience whose support Durkheim hoped to win for his sociological project. The concepts of Pierre Bourdieu and the literature on the rhetoric of the human sciences can help reconstruct the field of academic philosophy, Durkheim's relationship with it, and the ways in which he drew upon it to formulate his method and to persuade his philosophical colleagues. Durkheim's definition of the social fact in The Rules of Sociological Method can only be understood in the context of French academic philosophy. © 1996 John Wiley & Sons, Inc.     

Shortage of highly skilled workers in Hong Kong and policy responses

As Hong Kong develops into a knowledge-based economy, there is a strong increase in demand for highly educated and highly skilled workers. At the same time, many other countries are also experiencing shortages of highly-skilled workers as the development of hi-tech and information technology sectors have become an international trend. In this article, we study the changes in demand and supply of highly-skilled workers in Hong Kong and analyse the role that natural population growth, immigration, emigration, and return migration play in relation to the supply of highly-skilled workers. We also give an account of the policy responses of the government of the Hong Kong Special Administrative Region in its attempt to attract highly-skilled professionals as well as the challenges facing Hong Kong in the light of keen international competition.     

Defensive aggression in terns: Discrimination and response to individual researchers

The defensive responses of roseate terns (Sterna dougallii) were studied during the middle of the breeding season when all reproductive stages (incubation, chick-hatching, chick-rearing) were represented, to determine the factors affecting levels of nest defense and whether terns responded differently towards a familiar versus an unfamiliar researcher. Defensive aggression generally varied as a function of researcher identity, time of day, section or location in the colony and nest density. These variables explained from 60 to 66% of the variation in defensive aggression. More terns mobbed one researcher with more dive attacks than the other researcher. Terns were more aggressive in areas where the chicks had just hatched and were most vulnerable. © 1993 Wiley-Liss, Inc.
