This article examines the development of Russell's treatment of propositions, in relation to the topic of psychologism. In the first section, we outline the concept of psychologism, and show how it can arise in relation to theories of the nature of propositions. Following this, we note the anti-psychologistic elements of Russell's thought dating back to his idealist roots. From there, we sketch the development of Russell's theory of the proposition through a number of its key transitions. We show that Russell, (...) in responding to a variety of different problems relating to the proposition, chose to resolve these problems in ways that continually made concessions to psychologism.

Theories of language production have long been expressed as connectionist models. We outline the issues and challenges that must be addressed by connectionist models of lexical access and grammatical encoding, and review three recent models. The models illustrate the value of an interactive activation approach to lexical access in production, the need for sequential output in both phonological and grammatical encoding, and the potential for accounting for structural effects on errors and structural priming from learning.

There is already a copious literature comparing Claudius' oration on the admission of the primores Galliae into the Roman Senate with Tacitus’ account of the speech and of the opposition's case in Annals 11. 23–4. Yet the Emperor's own purpose in speaking as he did still needs some illumination. Scholarly concentration on technical points about the citizenship, on Claudius’ antiquarianism and on his debt to Livy has been fruitful, but it has often distracted attention from Claudius’ immediate aim. Meanwhile, Tacitus’ (...) interpretation has been insidious in colouring our view of what course of action the imperial orator was trying to defend before the Senate. (shrink)

This study investigated grammatical gender processing in school-age Spanish-English bilingual children using a visual world paradigm with a 4-picture display where the target noun was heard with a gendered article that was either in a context where all distractor images were the same gender as the target noun or in a context where all distractor images were the opposite gender than the target noun. We investigated 32 bilingual children who were exposed to Spanish since infancy and began learning English by (...) school entry. Along with the eye-tracking experiment, all children participated in a standardized language assessment and told narratives in English and Spanish, and parents reported on their child's current Spanish language use. The differential proportion fixations to target were analyzed in two time regions with linear mixed-effects models. Results show that prior to the target word being spoken, these bilingual children did not use the gendered articles to actively anticipate upcoming nouns. In the subsequent time region, it was shown that there are differences in the way they use feminine and masculine articles, with a lack of use of the masculine article and a potential facilitatory use of the feminine article for children who currently use more Spanish than English. This asymmetry in the use of gendered articles in processing is modulated by current Spanish language use and trends with results found for bilingual and second-language learning adults. (shrink)

The first section takes up some main details of American constitutional history. At the end of that section and in section two, we concentrate on one constitutional doctrine in particular, judicial review. We argue that this doctrine rests, traditionally, on the foundational idea of a permanent tension between democratic institutions and basic rights. In section three, we deal with the problem just raised, by suggesting an alternative view of the relationship that exists between these fundamental constitutional elements. Here we attempt (...) to show that there is an essential principled harmony between basic constitutional rights and democratic majority rule. And we try to locate judicial review within this alternative conception. Then in section four and in the conclusion we discuss the institutional arrangements for the practice of judicial review in the light of this alternative conception. (shrink)

Sustained attention, a key cognitive skill that improves during childhood and adolescence, tends to be worse in some emotional and behavioural disorders. Sustained attention is typically studied in non-affective task contexts; here, we used a novel task to index performance in affective versus neutral contexts across adolescence (N = 465; ages 11–18). We asked whether: (i) performance would be worse in negative versus neutral task contexts; (ii) performance would improve with age; (iii) affective interference would be greater in younger adolescents; (...) (iv) adolescents at risk for depression and higher in anxiety would show overall worse performance; and (v) would show differential performance in negative contexts. Results indicated that participants performed more poorly in negative contexts and showed age-related performance improvements. Those at risk of depression performed more poorly than those at lower risk. However, there was no difference between groups as a result of affective context. For anxiety there was no difference in performance as a function of severity. However, those with higher anxiety showed less variance in their reaction times to negative stimuli than those with lower anxiety. One interpretation is that moderate levels of emotional arousal associated with anxiety make individuals less susceptible to the distracting effects of negative stimuli. (shrink)

Professional identity and competent ethical behaviors of nursing students are commonly developed through curricular inclusion of professional nursing values education. Despite the enactment of this approach, nursing students continue to express difficulty in managing ethical conflicts encountered in their practice. This descriptive correlational study explores the relationships between professional nursing values, self-esteem, and ethical decision making among senior baccalaureate nursing students. A convenience sample of 47 senior nursing students from the United States were surveyed for their level of internalized professional (...) nursing values (Revised Professional Nursing Values Scale), level of self-esteem (Rosenberg’s Self-Esteem Scale), and perceived level of confidence in ethical decision making. A significant positive relationship (p < 0.05) was found between nursing students’ professional nursing values and levels of self-esteem. The results of this study can be useful to nursing educators whose efforts are focused on promoting professional identity development and competent ethical behaviors of future nurses. (shrink)

Working at The Hastings Center has been a tremendous professional stepping stone for me. I have long wanted to work in publishing, and I'm leaving the Center to work for America's oldest publisher, John Wiley and Sons. But I feel that my time here has been more than that‐that it has truly continued my education in ways I could not have anticipated. Thank you for letting me be part of your intellectual lives.

In this article, the author defends his claim that a subtle form of metaphysical dualism can be found in Alfred North Whitehead's central notion of the "actual occasion." Rosen contends that phenomenological philosophers such as Martin Heidegger go further than Whitehead in challenging traditional dualism.

Dennett, a philosopher, and Griffin, an ethologist, have recently presented influential arguments promoting the extended use of intentional language by students of animal behavior. This essay seeks to elucidate and to contrast the claims made by each of these authors, and to evaluate their proposals primarily from the perspective of a practicing comparative psychologist or ethologist. While Griffin regards intentional terms as explanatory, Dennett assigns them a descriptive function; the issue of animal consciousness is central to Griffin's (...) program and only tangentially related to Dennett's. The philosopher's arguments are founded upon a more coherent metaphysics, but Dennett neglects to substantiate his claim that animal competences can be most readily modelled by artificial intelligence specialists when they are described in intentional terms. Both authors assume that some examples of animal behavior should not be given an intentional characterization, but neither provides adequate guidelines for the identification of cases belonging to this negative set.

The paper describes the evolution of russell's theory of judgment between 1910 and 1913, With especial reference to his recently published "theory of knowledge" (1913). Russell abandoned the book and with it the theory of judgment as a result of wittgenstein's criticisms. These criticisms are examined in detail and found to constitute a refutation of russell's theory. Underlying differences between wittgenstein's and russell's views on logic are broached more sketchily.

This book discusses how rational choice theory grew out of RAND's work for the US Air Force. It concentrates on the work of William J. Riker, Kenneth J. Arrow, James M. Buchanan, Russel Hardin, and John Rawls. It argues that within the context of the US Cold War with its intensive anti-communist and anti-collectivist sentiment, the foundations of capitalist democracy were grounded in the hyper individualist theory of non-cooperative games.

The considerable attention to financial interests in clinical research has focused mostly on academic medical centers, even though the majority of clinical research is conducted in community practice settings. To fill this gap, this article maps the practices and policies in 73 community hospitals and several hundred specialized facilities around the country for reviewing clinical investigators’ financial relationships with research sponsors. Community hospitals face a substantially different mix of issues than academic medical centers do because their physician researchers are usually (...) not employees, and more of their studies are later-phase, multicenter trials. Accordingly, community physicians stand to benefit personally from per capita payments, but they tend to have less direct influence over research findings when compared with their academic peers. These and other contrasts require separate guidance for community-based organizations that takes into account their particular needs, circumstances, and institutional capacities. (shrink)

This (...) study describes the perceptions of individually interviewed spiritual leaders of the disease control measures used during the recent SARS outbreak in Toronto. Four central themes were identified: the relationship between religious obligation and civic responsibilities; the role of faith-based organizations in supporting public health restrictive measures; the reciprocal obligations of public health and religious communities during restrictions; and justifiable limits to duties to care. We conclude that, within certain constraints, spiritual leaders find restrictive measures ethically reasonable and that spiritual leaders can play an important role during pandemic and epidemic control planning. Public health officials should therefore include them in the early and ongoing deliberations of the criteria and logistics for implementation during public health emergencies.

What can the actions of stockbreeders, as they select the best individuals for breeding, teach us about how new species of wild animals and plants come into being? Charles Darwin raised this question in his famous, even notorious, Origin of Species (1859). Darwin's answer - his argument by analogy from artificial to natural selection - is the subject of our book. We aim to clarify what kind of argument it is, how it works, and why Darwin gave it such prominence. (...) As we explain more fully in our Introduction, we believe that the argument becomes much more intelligible when set, contextually, in a story stretching from classical Greek mathematics to modern evolutionary genetics: a long story, and a broad one too, encompassing everything from Darwin's earliest notebook theorising on the births and deaths of species, to agrarian capitalism as a distinctive form of economic life, to shifting Western reflections on art-nature relations.

Robots are now associated with various aspects of our lives. These sophisticated machines have been increasingly used in different manufacturing industries and services sectors for decades. During this time, they have been a factor in causing significant harm to humans, prompting questions of liability. Industrial robots are presently regarded as products for liability purposes. In contrast, some commentators have proposed that robots be granted legal personality, with an overarching aim of exonerating the respective creators and users of these artefacts from (...) liability. This article is concerned mainly with industrial robots that exercise some degree of self-control as programmed, though the creation of fully autonomous robots is still a long way off. The proponents of the robot’s personality compare these machines generally with corporations, and sporadically with, inter alia, animals, and idols, in substantiating their arguments. This article discusses the attributes of legal personhood and the justifications for the separate personality of corporations and idols. It then demonstrates the reasons for refusal of an animal’s personality. It concludes that robots are ineligible to be persons, based on the requirements of personhood. (shrink)

One method for investigating the neurobiology of consciousness is to experimentally manipulate consciousness as a variable and then visualize the resultant functional brain changes with advanced imaging techniques. To begin investigation into this area, healthy volunteers underwent positron emission tomography scanning while listening to randomized word lists in both conscious and unconscious conditions. Following anaesthesia, subjects had no explicit memories. Nonetheless, subjects demonstrated implicit memory on a forced-choice test . These subsequent memory scores were correlated with regional brain metabolism measured (...) during encoding. Conscious recall and unconscious recognition memory demonstrated considerable anatomic overlap in correlating significantly with relative glucose metabolism in auditory verbal memory areas. However, only conscious recall correlated with mediodorsal thalamic nucleus activity; unconscious recognition memory did not. These findings suggest that conscious versus unconscious memory distinctions may depend on the presence or absence of correlated thalamic activity, and directly implicate the thalamus in the neurobiology of consciousness.

William Burnside was one of the three most important algebraists who were involved in the transformation of group theory from its nineteenth-century origins to a deeper twentieth-century subject. Building on work of earlier mathematicians, they were able to develop sophisticated tools for solving difficult problems. His works are of enormous historical importance; they remain also a source of inspiration and information. The works of his contemporaries, such as Klein, Frobenius, Schur, have been published as also have the works of his (...) immediate successors such as Phillip Hall. All of Burnside's papers are reproduced here, organized chronologically and with a detailed bibliography. Walter Feit has contributed a foreword, and a collection of introductory essays are included to provide a commentary on Burnside's work and set it in perspective along with a modern biography that draws on archive material. This is the first reference volume of Burnside's collected papers, enhanced by a series of critical essays on his work, and is important for group theorists and historians and philosophers of mathematics and fills the gap in this area of literature.

The quantum probability flux of a particle integrated over time and a distant surface gives the probability for the particle crossing that surface at some time. We prove the free fluxacross-surfaces theorem, which was conjectured by Combes, Newton and Shtokhamer [1], and which relates the integrated quantum flux to the usual quantum mechanical formula for the cross section. The integrated quantum flux is equal to the probability of outward crossings of surfaces by Bohmian trajectories in the scattering regime.
