It is argued that “human-centredness” will be an important characteristic of systems that learn tasks from human users, as the difficulties in inductive inference rule out learning without human assistance. The aim of “programming by example” is to create systems that learn how to perform tasks from their human users by being shown examples of what is to be done. Just as the user creates a learning environment for the system, so the system provides a teaching opportunity for the user, (...) and emphasis is placed as much on facilitating successful teaching as on incorporating techniques of machine learning. If systems can “learn” repetitive tasks, their users will have the power to decide for themselves which parts of their jobs should be automated, and teach the system how to do them — reducing their dependence on intermediaries such as system designers and programmers.This paper presents principles for programming by example derived from experience in creating four prototype learners: for technical drawing, text editing, office tasks, and robot assembly. A teaching metaphor (a) enables the user to demonstrate a task by performing it manually, (b) helps to explain the learner's limited capabilities in terms of a persona, and (c) allows users to attribute intentionality. Tasks are represented procedurally, and augmented with constraints. Suitable mechanisms for attention focusing are necessary in order to control inductive search. Hidden features of a task should be made explicit so that the learner need not embark on the huge search entailed by hypothesizing missing steps. (shrink)

Traditional forms of farming, herding, and fishing are remarkably adapted to African conditions but these traditional approaches are being overtaken by modern pressures, particularly population growth. According to a report published by the Office of Technology Assessment (OTA), a nonpartisan analytical support agency of the U. S. Congress, one promising way to help African farmers and herders would be for development assistance organizations to focus more attention on the various forms of low-resource agriculture that predominate in Africa.In keeping with OTA's (...) mission and primary audience, “Enhancing Agriculture in Africa: A Role for U. S. Development Assistance” (1988) is a policy-oriented synthesis of available technical information. The report provides Congress with a range of options that, if pursued, could help Africans enhance agriculture, increase their food security, and improve their lives.This paper is drawn from the larger OTA report, and it focuses on the role technology might play in enhancing low-resource agriculture. Readers should see the full assessment (OTA, 1988) for more information on policy considerations; the specific technologies mentioned; or a complete list of advisory panel members, workshops and participants, and commissioned papers.OTA's report comes at a critical time: for a variety of reasons—ranging from changing values to increased budget constraints—U. S. foreign assistance policy is undergoing a fundamental reevaluation. This review of the potential of low-resource agriculture, and options the United States might pursue to enhance this approach, was intended to aid in this reevaluation. (shrink)

I hope to persuade Charles Fried to think again about his developing views on distributive justice. Since I live at a certain remove from Cambridge, the best I can offer is a hypothetical dialogue with an imaginary person whose views seem, to me at least, of a Friedian inspiration. My central question deals with the way Fried establishes his rights to things he candidly concedes he does not deserve. To present my problems, I shall begin with a simpler case than (...) those – involving kidneys and talents – that Fried makes central to his discussion. Rather than starting with these rather special goods, I find it clarifying to focus first on more garden variety commodities – which, to emphasize their character, I shall call apples. (shrink)

The question whether the study of education and teacher education belong at a liberal arts college deserves careful consideration. In this essay Bruce Kimball analyzes and finds unpersuasive the three principled rationales that are most often advanced on behalf of excluding educational studies, teacher education, or both from a liberal arts college. Specifically, Kimball argues that no principled definition of the conventional liberal arts disciplines excludes the study of education without barring other fields now regarded as legitimate, and consistency (...) demands that all such fields be excluded if any are. In addition, teacher education, even if considered as merely “craft know-how” or as professional training, cannot be excluded from liberal arts colleges without arbitrarily classifying it as suspect and subjecting it to strict scrutiny. But the question of whether educational studies or teacher education fit any asserted definition of liberal education does not finally resolve the question of whether they belong in a liberal arts college. Kimball concludes by suggesting that there are moral and prudential reasons for liberal arts colleges to offer teacher education and, concomitantly, the study of education, even apart from the unpersuasive objections that they do not fit a definition of liberal education.

As the applied field of social work attempts to become more of a sciencebased profession, it is relying more on the findings from empirical research studies. Withinsocial work there is little discussion of the philosophy of science underlying conventional research inquiry. This paper introduces some major philosophical principles that undergird scientific investigations of the causes of societal and psychosocial problems and of the effectiveness of structured programs, policies and practices to ameliorate social ills. Among the principles introduced are the philosophical (...) concepts of determinism, empiricism, realism, operationalism, scientific materialism, parsimony, logic, and positivism. Together these philosophical assumptions provide a pragmatic framework to design and conduct scientific research of value to the social work profession and other fields. (shrink)

Word in noise identification is facilitated by acoustic differences between target and competing sounds and temporal separation between the onset of the masker and that of the target. Younger and older adults are able to take advantage of onset delay when the masker is dissimilar to the target word, but only younger adults are able to do so when the masker is similar. We examined the neural underpinning of this age difference using cortical evoked responses to words masked by either (...) Babble or Noise when the masker preceded the target word by 100 or 600 ms in younger and older adults, after adjusting the signal-to-noise ratios to equate behavioural performance across age groups and conditions. For the 100 ms onset delay, the word in noise elicited an acoustic change complex response that was comparable in younger and older adults. For the 600 ms onset delay, the ACC was modulated by both masker type and age. In older adults, the ACC to a word in babble was not affected by the increase in onset delay whereas younger adults showed a benefit from longer delays. Hence, the age difference in sensitivity to temporal delay is indexed by early activity in the auditory cortex. These results are consistent with the hypothesis that an increase in onset delay improves stream segregation in younger adults in both noise and babble, but only in noise for older adults and that this change in stream segregation is evident in early cortical processes.

In three parts, this volume in the AP-LS series explores the phenomena of captivity and risk management, guided and informed by the theory, method, and policy of psychological jurisprudence. The authors present a controversial thesis that demonstrates how the forces of captivity and risk management are sustained by several interdependent "conditions of control." These conditions impose barriers to justice and set limits on citizenship for one and all. Situated at the nexus of political/social theory, mental health law and jurisprudential ethics, (...) the book examines and critiques constructs such as offenders and victims; self and society; therapeutic and restorative; health; harm; and community. So, too, are three "total confinement" case law data sets on which this analysis is based. The volume stands alone in its efforts to systematically "diagnose" the moral reasoning lodged within prevailing judicial opinions that sustain captivity and risk management practices impacting: (1) the rights of juveniles found competent to stand criminal trial, the mentally ill placed in long-term disciplinary isolation, and sex offenders subjected to civil detention and community re-entry monitoring; (2) the often unmet needs of victims; and (3) the demands of an ordered society. Carefully balancing sophisticated insights with concrete and cutting-edge applications, the book concludes with a series of provocative, yet practical, recommendations for future research and meaningful reform within institutional practice, programming, and policy.

Purely parallel neural networks can model object recognition in brief displays – the same conditions under which illusory conjunctions have been demonstrated empirically. Correcting errors of illusory conjunction is the “tag-assignment” problem for a purely parallel processor: the problem of assigning a spatial tag to nonspatial features, feature combinations, and objects. This problem must be solved to model human object recognition over a longer time scale. Our model simulates both the parallel processes that may underlie illusory conjunctions and the serial (...) processes that may solve the tag-assignment problem in normal perception. One component of the model extracts pooled features and another provides attentional tags that correct illusory conjunctions. Our approach addresses two questions: How can objects be identified from simultaneously attended features in a parallel, distributed representation? How can the spatial selectional requirements of such an attentional process be met by a separation of pathways for spatial and nonspatial processing? Our analysis of these questions yields a neurally plausible simulation of tag assignment based on synchronizing feature processing activity in a spatial focus of attention. (shrink)

Mimetic theory draws support from diverse disciplines in the humanities and social sciences. But arguably Girard would have even more influence if his theory had stronger life data, and one field well positioned to provide such input is psychology. Girard distinguished his thinking from Freud, while critiquing the psychoanalytic tradition more generally, in Book III of Things Hidden since the Foundation of the World1—a work taking the form of an extended dialogue with two psychiatrists. One of these, Jean-Michel Oughourlian, has (...) begun to develop the Girard-inspired practice of "interdividual psychology."2 In Girard's own hands, albeit to a limited degree, mimetic theory has been applied to mental health issues.3...

US courts regulate civil advocates in two ways. First, state judiciaries adopt rules of professional conduct that include provisions governing lawyers' work in civil litigation. Additionally, in the course of ruling on sanctions motions in civil lawsuits, courts develop and enforce standards of conduct on an ad hoc basis in common law fashion. Sometimes rules of conduct incorporate the case law and sometimes the case law builds on professional conduct rules, but other times the rules and case law diverge. This (...) article discusses the role of rules and case law in regulating US civil advocates, the relationship between rules and case law, and the comparative advantages of each. (shrink)

In this narrative, we explore the story of Ananias and Sapphira from the book of Acts in the Christian scriptures. We examine the story in the light of a recent book by Dominic Johnson, God Is Watching You, and other related research. The idea of a punitive God and/or the belief in a punitive God may have significant effects on group functioning. The troubling story of Ananias and Sapphira may be seen as a central cog in the cooperative coming together (...) of what became the Christian Church. In our modern world, a punitive God is an idea we seek to avoid but it may be the one that is essential for a peaceful cooperative world. (shrink)

In lieu of an abstract, here is a brief excerpt of the content:Book Reviews St. Auc~stine and Being: A Me$aphyM,cal Essay. By James F. Anderson. (The Hague: Martinus Nijhoff, 1965.Pp. viii [i] + 76. Guilders 9.90.) Contemporary students of medieval philosophy, especially those influenced by the writings of Gilson, usually view Augustine as primarily an essentialist in metaphysics, while Aquinas is viewed as some sort of existentialist. This is taken to mean that, whereas Augustine seems to identify being with essence (...) or wha~ a thing is, Aquinas distinguishes between what a thing is and its act of existence. The major contribution of Aquinas to later philosophy is often depicted as this distinction between essence and existence. Perhaps the major interest and value of Professor Anderson's essay is that it contests this currently predominant opinion of the essentialist character of Augustinian metaphysics and calls for a re-evaluation of the supposedly revohi~ionary character of the Thomistic concentration upon the act of existence. It is quite evident that Augustine broke with Plotinus when he asserted that the first principle of all things was God, being itself (ipsum esse), rather than the One, which transcends being. The controversy arises over Augustine's view of the nature of being (esse). For Gilson the notion of being remained for Augustine Neoplatonic, while for Anderson Augustine introduced an existential aspect to the notion of being lacking in Neoplatonic thought. Citing the same texts for support Gilson maintains that Augustine interprets the name of God given in Exodus as "I am he who never changes," while Anderson maintains that Augustine interprets Exodus as asserting that God is being, in the sense of existence, itself. The major point of disagreement between Gilson and Anderson is not whether Augustine regarded being as pre~ dominant, but how Augustine interpreted the notion of being. In some texts Augustine maintsSns that being and immutability mean the same thing, in others he argues that a thing truly is 'because it is immutable, and in yet others he argues that a thing is immutable because it truly is. The first opinion seems to be the one frequently favored as an interpretation of Augustine by Gilson. The second is usually regarded as Neoplatonic. The third is the opinion which Professor Anderson argues was most accurately Augustine's. According to Professor Anderson the first two opinions reflect for Augustine a merely factual connection between being and immutability, whereas the third reflects a metaphysical entailment. I should like to mention three points in Professor Anderson's discussion which seem to me weak. Firstly, as Augustine remarks that being is the name for unchangeableness we cannot take this as asserting a merely factual relationship. Secondly, to say that 'being' and 'immutability ~mean the same thing to Augustine or that being and immutability are identical to him does not necessitate, as Professor Andersen claims, denying the primacy of being. If 'being' and 'immutability' mean the same thing, then it is very peculiar to ask which is primary. If it is remarked that 'triangleI means the same thing as 'three sided figure', what sense does it make to ask which notion is primary? I suspect that Professor Anderson's contention makes sense only if one believes that there is a difference in the meanings of 'being' and 'immutability ', but whether or not there was such a difference for Augustine is precisely the point at issue. Professor Anderson asserts that it would be a "metaphysical inconsistency" to claim that God is both being and immutability, but it is not clear why such a claim would be inconsistent if the two terms in fact mean the same thing (p. 30). Thirdly, if, as is in fact the case, Augustine's remarks on the relationship between immutability and being are inconsistent perhaps we should accept the possibility that Augustine himself never came to a clear view on this matter rather than attempt to surmise what Augustine "must have meant." Of course, such inconsistency in Augustine's writings would tend to support the thesis of Gilson that Augustine has difficulties reconciling his theology and metaphysics. Moreover, the analogy Professor Anderson suggests between the Augustinian mutability-immutability contrast and the Thomistic potency-act contrast could only be a very rough one... (shrink)

Chow's defense of NHSTP is masterful. His dismissal of including effect sizes (ES) is misplaced, and his failure to discuss the additional practice of reporting proportions of variance explained (PVE) is an important omission. Reporting the results of inferential statistics will be greatly enhanced by including ES and PVE when results are first determined to be statistically significant.

This article further elaborates on the “pre-crime society” thesis as developed and examined by Arrigo and Sellers. Specifically, the article focuses on the ultramodern era of digital inter-connectivity and argues that productive psychic desire is held clinically captive. Ultra-modernity is populated by cyber-forms of human relating and of economic exchange that nurture hyper-securitization. We discuss how the maintenance of hyper-securitization supports a pre-crime society, and how hyper-securitization’s object of desire consists of sign-optics. We argue that the co-constitutive forces of this (...) desire represent the sign-exchange values of post-criminology. Post-criminology’s signifiers include, among others, “predictive policing”, “crime mapping”, and “actuarial penology.” Post-criminology’s signifieds produce captivity-generating bio-digital “laws” of human relatedness. Among others, these laws sanction the neurosis of de-vitalization and certify the psychosis of finalization. We explain how the unchecked excess neutralizations of de-vitalization and finalization cultivate clinical captivity. Clinical captivity is a social anxiety in which reciprocal consciousness, inter-subjectivity, and mutual power are limited in existence or are denied an existence. (shrink)

The Philosophical Legacy of Behaviorism is the first book to describe the unique contributions of a behavioral perspective to the major issues of philosophy. Leading behavioral philosophers and psychologists have contributed chapters on: the origins of behaviorism as a philosophy of science; the basic principles of behaviorism; ontology; epistemology; values and ethics; free will, determinism and self-control; and language and verbal behavior. A concluding chapter provides an overview of some scholarly criticisms of behavioral philosophy. Far from espousing a `black box' (...) perspective on human cognition and philosophical reasoning, behaviorism (as derived from the works of B. F. Skinner) represents a contemporary and viable approach to conceptualizing important philosophical and psychological issues. Audience: This work will make an excellent text for upper-level undergraduates and graduate students in the fields of philosophy and psychology, as well as being of interest to established scholars in those disciplines.

The problem for the CNS in any particular movement task is to coordinate the various frames of reference appropriate to the task. Control variables are determined by this coordination. The coordination problem varies greatly from task to task, and so no single set of control variables is likely to account for a broad range of movement tasks.

A key issue of contention between political philosophers has been the quest to resolve the tension between self-determination and the recognition of the intersubjective nature of self-development. This paper will argue that although the early work of Jean-Paul Sartre was characterised by the attempt to avoid defining self-determination as un-situated, in trying to situate self-determination Sartre paradoxically endorsed a radical notion of separation. This paradox manifested itself most clearly in his profoundly problematic account of intersubjectivity. Rather than denying the importance (...) of intersubjectivity as is often supposed, Sartre in fact showed a deep awareness of its centrality even though his account of intersubjectivity was premised upon the inevitability of eternal antagonism. The paper will conclude by arguing that the problems in Sartre's arguments may lead to a more secure definition of autonomy and thereby, point toward more hopeful attempts to resolve the tension between autonomy and intersubjectivity.
