On the effects of signaling reinforcer probability and magnitude in delayed matching to sample

Two experiments examined whether postsample signals of reinforcer probability or magnitude affected the accuracy of delayed matching to sample in pigeons. On each trial, red or green choice responses that matched red or green stimuli seen shortly before a variable retention interval were reinforced with wheat access. In Experiment 1, the reinforcer probability was either 0.2 or 1.0 for both red and green responses. Reinforcer probability was signaled by line or cross symbols that appeared after the sample had been presented. In Experiment 2, all correct responses were reinforced, and the signaled reinforcer durations were 1.0 s and 4.5 s. Matching was more accurate when larger or more probable reinforcers were signaled, independently of retention interval duration. Because signals were presented postsample, the effects were not the result of differential attention to the sample.     

The Structure of the Ordinals and the Interpretation of ZF in Double Extension Set Theory

Andrzej Kisielewicz has proposed three systems of double extension set theory of which we have shown two to be inconsistent in an earlier paper. Kisielewicz presented an argument that the remaining system interprets ZF, which is defective: it actually shows that the surviving possibly consistent system of double extension set theory interprets ZF with Separation and Comprehension restricted to ₀ formulas. We show that this system does interpret ZF, using an analysis of the structure of the ordinals.     

Adolescent Psychopathy and Personality Theory—the Interpersonal Circumplex: Expanding Evidence of a Nomological Net

The construct validity of psychopathy was examined in a sample of 114 male and female young offenders (M_age = 15.16) at a southeastern detention center. The interpersonal circumplex served as a framework of general personality from which to examine the construct of adolescent psychopathy. A supplementary analysis of the psychopathy measures and the Big 5 factors of personality was also conducted using a matrix approach. Measures included: (a) Antisocial Process Screening Device (P. J. Frick & R. D. Hare, 2001); (b) Child Psychopathy Scale (D. R. Lynam, 1996); (c) Psychopathy Checklist—Youth Version (A. E. Forth, D. S. Kosson, & R. D. Hare, 2003); and (d) Interpersonal Adjective Scales Revised—Big 5 Version (P. Trapnell & J. S. Wiggins, 1991; J. S. Wiggins, 1995). Results showed substantial convergence among the three psychopathy measures. In addition, meaningful associations between psychopathy and constructs within the interpersonal circumplex and broader domains of the Big 5 were obtained. Two psychopathy scales correlated to a higher degree than expected with neuroticism. These findings provide evidence linking personality theory to the concept of child and adolescent psychopathy, thereby adding to its construct validity. However, they do so with the caveat that youth may also be displaying some characteristics of neuroticism, suggesting that worry and anxiety may accompany psychopathic features in earlier developmental stages. The implications of the current study are discussed.     

Communication flow and change theory within a family therapy supervision model

This article portrays a model of family therapy clinical supervision using change theory that is most appropriate for use with the videotape, audiotape, case presentation and debriefing from the live session. The most powerful tool during this process is that of communication and assessment of change theorys tools of confidence and conviction. The concepts presented are meant to add an additional dimension to family therapy supervision in cooperation of other theories, not as an end in themselves.Special thanks to Ms. Geri Koncilja of the Informational Technology Center at Colorado State University, Pueblo for illustration and graphic assistance.     

传统儒家、道家哲学生态观比较

儒家、道家哲学生态观既有共同点,又存在差异。在生态存在论上,两者都是一种生成论世界观,强调人与自然万物的内在联系。不过,道家注重自然运化过程的自然性、一体性,儒家则强调自然运化的生命特征,肯定人与万物的差别;在生态价值论上,道家偏重“自然”的价值．强调自然运化的自然目的性和价值性,肯定人和万物的自然本性的价值。儒家则偏重“人文”价值。它强调人与社会的生存价值．肯定主体德性的价值;在生态实践观上,道家强调“自然无为”的实践原则,“自然无为”体现了对自然自组织、自协调智慧的信任。道家实践观体现在个人生活方式上具有消减性特征,强调慈爱利物、俭啬有度、知和不争。儒家强调发挥人的主体能动性,肯定主体对人与社会、人与自然关系的协调作用。在对农业生产实践的治理上。儒家强调顺应天时、因地制宜和“谨其时禁”。     

Liberalism and the Privatised Family: The Legacy of Rousseau

This article argues that the intellectual legacy of Rousseau is at the root of the failure of 20th century egalitarian theorists such as Rawls and Dworkin to engage intellectually with feminist theorists working within the liberal tradition. Through an extended critique of Rousseau’s delineation of the relationship between liberal citizenship and the private family, it argues that the failure of such liberal theorists to take gender hierarchy seriously is a consequence of their attempt to place the private family outside the sphere not only of politics, but also of justice.     

“Hands up Who Wants to Die?”: Primoratz on Responsibility and Civilian Immunity in Wartime

The question of the morality of war is something of an embarrassment to liberal political thinkers. A philosophical tradition which aspires to found its preferred institutions in respect for individual autonomy, contract, and voluntary association, is naturally confronted by a phenomenon that is almost exclusively explained and justified in the language of States, force and territory. But the apparent difficulties involved in providing a convincing account of nature and ethics of war in terms of relations between individuals has not prevented liberal theorists from attempting this task. This paper examines a recent attempt by Igor Primoratz to sketch out the implications of a consistent liberalism for just war doctrine and, in particular, as regards the question of who may be a legitimate target of attack in wartime. Primoratz’s paper itself is a critique of Michael Waltzer’s authoritative exposition of just war theory for failing to be sufficiently and consistently liberal. The debate between these two authors is a productive site for investigating the potential and limitations of liberal theories of just war.     

Swimming against the mainstream: the early years from chilly tributary to transformative mainstream

This article traces the transformative paradigm shift in the theory and practice of personal change. Within a decade, new conceptual models, analytic methodologies and modes of treatment were created. Treatments were altered in the content, locus, and agents of change. This enterprising period also witnessed a sweeping shift in the public acceptance of behaviorally oriented treatments. The present article also analyzes the evolving theorizing and applications of social cognitive theory rooted in modeling, self-regulatory, and self-efficacy mechanisms of psychosocial change. This model of change is implemented from an agentic perspective to promote personal, institutional, and society-wide changes that address some of the most urgent global problems.     

Praxis and Agency in Foucault’s Historiography

This paper examines the consequences for agency that Foucaults historiographical approach constructs. The analysis begins by explaining the difference between legislative history and exemplary history, drawing parallels to similar theoretical distinctions offered in the works of Max Weber, J.L. Austin, and Zygmunt Bauman. The analysis continues by reading Habermass critique of Foucault through the tropological lenses suggested by White [Metahistory. Baltimore, MD: Johns Hopkins University Press, 1973]; it argues that Habermass critique misrecognizes the tropes of Foucaultian genealogy. The paper draws implications for education by articulating possibilities for praxis and agency in terms of pedagogy specifically related to the distinction between didactics and modeling. The paper concludes by suggesting that genealogy does not play by Hegels rules, but rather exemplifies agency in ways that are not recognizable from a modernist perspective.
