This volume provides the first complete edition of the third and final surviving draft of John Locke's Essay Concerning Human Understanding, dating from 1685, four years before the publication of the Essay itself (December 1689). There is a General Introduction that gives a detailed account of the content and circumstances of composition of this draft, and a Textual Introduction that provides a full description of the manuscript and its0history.

Most empirical work in human categorization has studied learning in either fully supervised or fully unsupervised scenarios. Most real-world learning scenarios, however, are semi-supervised: Learners receive a great deal of unlabeled information from the world, coupled with occasional experiences in which items are directly labeled by a knowledgeable source. A large body of work in machine learning has investigated how learning can exploit both labeled and unlabeled data provided to a learner. Using equivalences between models found in human categorization and (...) machine learning research, we explain how these semi-supervised techniques can be applied to human learning. A series of experiments are described which show that semi-supervised learning models prove useful for explaining human behavior when exposed to both labeled and unlabeled data. We then discuss some machine learning models that do not have familiar human categorization counterparts. Finally, we discuss some challenges yet to be addressed in the use of semi-supervised models for modeling human categorization. (shrink)

On Becoming an Effective Teacher presents the final unpublished writings of Rogers and as such has a unique historical value. It also documents the research results of four highly relevant, related but independent studies which comprise the biggest collection of data ever accumulated to test a person-centred theory in the field of education. This body of comprehensive research on effective teaching was accomplished over a twenty-year period in 42 States in the U.S. and in six other countries including the (...) UK, Germany, Brazil, Canada, Israel, and Mexico, and is highly relevant to the concerns of teachers, psychologists, students, and parents. The principal findings of the research in this book show that teachers and schools can significantly improve their effectiveness through programs focusing on facilitative interpersonal relationships. Teachers who either naturally have, or are trained to have empathy, genuineness (congruence), and who prize their students (positive regard) create an important level of trust in the classroom and exert significant positive effects on student outcomes including achievement scores, interpersonal functioning, self-concept, and attendance. The dialogues between Rogers and Lyon offer a unique and timeless perspective on teaching, counselling and learning. The work of Reinhard Tausch on person-centered teaching to counselors, parents, athletics, and even textbook materials, as well as research on the interactions of teachers and students, is among the most thorough and rigorous research ever accomplished on the significance and potential of a person-centered approach to teaching and learning.

"Biodiversity prospecting" has been touted as a mechanism for both discovering new pharmaceutical products and saving endangered ecosystems. It is unclear what values may arise from such activities, however. Evidence from transactions is incomplete and existing theoretical models are flawed. We calculate an upper bound on the value of the "marginal species." Even under favorable assumptions this bound is modest. Slightly modified assumptions lead to drastically lower estimates. We extend our findings to the value of the marginal hectare of habitat (...) and find that the incentives for habitat conservation generated by private pharmaceutical research are also, at best, very modest.

More than 200 million children under the age of 5 years are affected by malnutrition worldwide according to the World Health Organization. The Barbados Nutrition Study (BNS) is a 55-year longitudinal study on a Barbadian cohort with histories of moderate to severe protein-energy malnutrition (PEM) limited to the first year of life and a healthy comparison group. Using quantitative electroencephalography (EEG), differences in brain function duringchildhood(lower alpha1 activity and higher theta, alpha2 and beta activity) have previously been highlighted between participants (...) who suffered from early PEM and controls. In order to determine whether similar differences persisted intoadulthood, our current study used recordings obtained during a Go-No-Go task in a subsample of the original BNS cohort [population size (N) = 53] at ages 45–51 years. We found that previously malnourished adults [sample size (n) = 24] had a higher rate of omission errors on the task relative to controls (n= 29). Evoked-Related Potentials (ERP) were significantly different in participants with histories of early PEM, who presented with lower N2 amplitudes. These findings are typically associated with impaired conflict monitoring and/or attention deficits and may therefore be linked to the attentional and executive function deficits that have been previously reported in this cohort in childhood and again in middle adulthood.

In two studies, we explored the frequency and phenomenology of musical imagery. Study 1 used retrospective reports of musical imagery to assess the contribution of individual differences to imagery characteristics. Study 2 used an experience sampling design to assess the phenomenology of musical imagery over the course of one week in a sample of musicians and non-musicians. Both studies found episodes of musical imagery to be common and positive: people rarely wanted such experiences to end and often heard music that (...) was personally meaningful. Several variables predicted musical imagery, including personality, musical preferences, and positive mood. Musicians tended to hear musical imagery more often, but they reported less frequent episodes of deliberately-generated imagery. Taken together, the present research provides new insights into individual differences in musical imagery, and it supports the emerging view that such experiences are common, positive, and more voluntary than previously recognized.

This article describes the development of a computerized version of a measure of ethical sensitivity to racial and gender intolerance, the Racial Ethical Sensitivity Test. The REST was based on James Rest's 4-component model of moral development and the professional codes of ethics from school-based professions. The new version, Racial and Ethical Sensitivity Test-Compact Disk, consists of 5 videotaped scenarios followed by an interactive "interview" presented on compact discs. Data from a study with 58 students provides initial validation of the (...) REST-CD. Ethical sensitivity to racial and gender intolerance in schools, as measured by the REST-CD, was moderately related to attitudes toward racial and gender equity issues in society as measured by the Quick Discrimination Index. The results provide evidence for both interrater and internal reliability of the REST-CD scores. This study also tests the hypothesized relationship between REST-CD scores and previous multicultural and ethics course work. Students with multicultural and ethics course experience have scored significantly higher on the REST-CD than students without course work. The paper-and-pencil tests are not significantly related to previous ethics/multicultural course work. In this article, we discuss the implications of the results and directions for future research.

The format of this book is unusual, especially for a book about linguistics. The book is meant primarily as a research monograph aimed at linguists who have some background in formal semantics, e. g. Montague Grammar. However, I have two other audiences in mind. Linguists who have little or no experience of formal semantics, but who have worked through a basic mathematics for linguists course (e. g. using Wall, 1972, or Partee, 1978), should, perhaps with the help of a sympathetic (...) Montague gramma rian, be able to discover enough of how I have adapted some of the basic ideas in formal semantics to make the developments that I undertake in the rest of the book accessible. Logicians and computer scientists who know about model theoretic semantics and formal systems should be able to glean enough from Chapters I and II about linguistic concerns and techniques to be able to read the remainder of the book, again possibly with the help of a sympathetic Montague grammarian. However, readers should beware. Chapter II is not meant as a general introduction either to formal semantics or to linguistics and while much of the presentation there is going over ground that is already well covered in the literature, the particular formulation and the emphases are very much oriented to the developments to be undertaken later in the book.

The development of ethical and practice guidelines related to mental health service on the Internet has lagged behind the movement of practitioners into this area. Even for clinicians who are not offering services on the Web, the Internet has led to confusion and concern about proper roles and responsibilities. This article discusses an actual experience we had with a self-described rationally suicidal man with multiple sclerosis. After presenting some background on MS, we report initial interactions with the man verbatim and (...) summarize subsequent correspondence in an analysis of the man's claim that his decision to die was well reasoned and that he should be allowed a physician's assistance.

This collection of essays on themes in the work of John Locke , George Berkeley , and David Hume , provides a deepened understanding of major issues raised in the Empiricist tradition. In exploring their shared belief in the experiential nature of mental constructs, The Empiricists illuminates the different methodologies of these great Enlightenment philosophers and introduces students to important metaphysical and epistemological issues including the theory of ideas, personal identity, and skepticism. It will be especially useful in courses devoted (...) to the history of modern philosophy. (shrink)

Studies of the conceptual abilities of nonhuman primates demonstrate the substantial range of these abilities as well as their limitations. Such abilities range from categorization on the basis of shared physical attributes, associative relations and functions to abstract concepts as reflected in analogical reasoning about relations between relations. The pattern of results from these studies point to a fundamental distinction between monkeys and apes in both their implicit and explicit conceptual capacities. Monkeys, but not apes, might be best regarded as (...) “paleo‐logicans” in the sense that they form common class concepts of identity on the basis of identical predicates (i.e., shared features). The discrimination of presumably more abstract relations commonly involves relatively simple procedural strategies mediated by associative processes likely shared by all mammals. There is no evidence that monkeys can perceive, let alone judge, relations‐between‐relations. This analogical conceptual capacity is found only in chimpanzees and humans. Interestingly, the “analogical ape,” like the child, can make its analogical knowledge explicit only if it is first provided with a symbol system by which propositional representations can be encoded and manipulated.

Grush and Churchland (1995) attempt to address aspects of the proposal that we have been making concerning a possible physical mechanism underlying the phenomenon of consciousness. Unfortunately, they employ arguments that are highly misleading and, in some important respects, factually incorrect. Their article ‘Gaps in Penrose’s Toilings’ is addressed specifically at the writings of one of us (Penrose), but since the particular model they attack is one put forward by both of us (Hameroff and Penrose, 1995; 1996), it is appropriate (...) that we both reply; but since our individual remarks refer to different aspects of their criticism we are commenting on their article separately. The logical arguments discussed by Grush and Churchland, and the related physics are answered in Part l by Penrose, largely by pointing out precisely where these arguments have already been treated in detail in Shadows of the Mind (Penrose, 1994). In Part 2, Hameroff replies to various points on the biological side, showing for example how they have seriously misunderstood what they refer to as ‘physiological evidence’ regarding to effects of the drug colchicine. The reply serves also to discuss aspects of our model ‘orchestrated objective reduction in brain microtubules – Orch OR’ which attempts to deal with the serious problems of consciousness more directly and completely than any previous theory.

In searching for an appropriate utility function in the expected utility framework, we formulate four properties that we want the utility function to satisfy. We conduct a search for such a function, and we identify Pareto utility as a function satisfying all four desired properties. Pareto utility is a flexible yet simple and parsimonious two-parameter family. It exhibits decreasing absolute risk aversion and increasing but bounded relative risk aversion. It is applicable irrespective of the probability distribution relevant to the prospect (...) to be evaluated. Pareto utility is therefore particularly suited for catastrophic risk analysis. A new and related class of generalized exponential (gexpo) utility functions is also studied. This class is particularly relevant in situations where absolute risk tolerance is thought to be concave rather than linear. (shrink)

This book presents the theory of capital utilization, a discussion of the econometrics of capital utilization, and econometric tests of the theory using international data. Capital utilization, defined as the proportion of time that capital is working productively, is mainly affected by shift-working. Capital utilization is an important economic variable that has received serious attention from economists only since the mid-1960s In the first part, the authors provide a synthesis of current knowledge, combining a consistent statement of existing theory with (...) some major extensions. In the second part, they turn to the econometrics, first discussing the appropriate methodology and then testing the theory on data from several countries. This empirical work is considerably more sophisticated than previous studies on this topic. Having established the theory and tested it, they move on to consider policy, the relationship between capital utilization and economic growth, and the place of shift-work in the dual economy.

Evidence from optic ataxic patients with bilateral lesions to the superior parietal lobes does not support the view that there are separate planning and control mechanisms located in the IPL and SPL respectively. The aberrant reaches of patients with bilateral SPL damage towards extrafoveal targets seem to suggest a deficit in the selection of appropriate motor programmes rather than a deficit restricted to on-line control.

H. L. A. Hart’s The Concept of Law (Hart 1994) contains many passages that have become iconic for legal theory. This essay focuses on Chapter 7, sections 1 and 2, and Hart’s comments about judicial discretion in the context of Ronald Dworkin’s well-known attack on the idea of judicial discretion in his essay “The Model of Rules”. Specifically, the paper undertakes three projects. The first project is to defend the importance of the fundamental picture that Hart presents in Concept, Chapter (...) 7 of Common-Law judicial rule-making. Hart represents such rule-making as a balance of certainty and flexibility, and he is correct to do that. The second project is to argue that Dworkin’s attack on the positivist model of common-law judicial rule-making as an exercise of “strong discretion” fails. The idea, central to the meaning of “strong discretion” that courts are not “not bound by standards set by the authority in question” cannot be established. The third is to argue that Hart is his own worst enemy. The language, metaphors and images he uses to present his account of common-law judicial rule-making open the way to Dworkin’s critique. They also reveal Hart, if the language, metaphors and images are taken seriously, to be precisely the kind of formalist or deductivist about adjudication that he is ostensibly in Concept Chapter 7 criticising.Resumen:El concepto de derecho (1994) de H. L. A. Hart, contiene muchos pasajes que se han convertido en íconos de la teoría jurídica. Este artículo se concentra en el capítulo 7, sección 1 y 2, y en los comentarios que realizara Hart sobre la discreción judicial en el contexto de la bien conocida crítica de Dworkin a esta misma idea en su ensayo “El modelo de las normas”. Específicamente, el artículo emprende tres proyectos. El primero de ellos consiste en defender la importancia del esquema fundamental que ofrece Hart en el capítulo 7 de su obra, esto es, la creación judicial de normas en el Common Law. Hart representa tal creación de normas como un balance de certeza y flexibilidad; y él está en lo correcto al presentarlo de tal modo. El segundo proyecto consiste en argumentar que la crítica de Dworkin al modelo positivista de la creación judicial de normas en el Common Law, como un ejercicio de “discreción fuerte”, no está sustentada. La idea —central para el significado de “discreción fuerte”— de que los tribunales no están “sujetos a criterios establecidos por la autoridad en cuestión” no puede ser establecida. El tercer proyecto consiste en argumentar que Hart es su peor enemigo. El lenguaje, las metáforas e imágenes que emplea para exponer su teoría de la creación judicial de normas en el Common Law abre la puerta a la crítica dworkiniana. Si tomamos en serio el lenguaje, las metáforas y las imágenes, encontraremos a un Hart del tipo formalista o deductivista sobre la adjudicación, justo como el que él mismo está abiertamente cuestionando en el capítulo 7 de El concepto.
