Wilfrid Sellars has been widely—though, I argue, largely mistakenly—criticized for his doctrine of picturing. I claim that a more thorough and accurate exposition of this doctrine shows that it does not suffer from alleged mistakes and, in addition, benefits Sellars’s general position by being the source for an “external” criterion of success for basic empirical truths, by providing a way to incorporate into his position the “mapping” processes of “animal representational systems,” and, finally, by being the philosophical piece in his (...) “functional” account of meaning that allows it to deal with “names.”.

Early sections of the paper develop a view of the natural numbers and a view of counting which are suggested by the remarks of several modern philosophers. Further investigation of these views leads to one of the main theses of the paper: a special kind of quantifier, the "numerical quantifier" is essential to counting. The remainder of the paper suggests the rudiments of a new view of the natural numbers, a view which maintains that numerical quantifiers are one kind of (...) natural number. (shrink)

Against the backdrop of Walter Benjamin's famous essay, “Unpacking My Library”, this article, by the Librarian of the Warburg Institute, tells the story of the many times that the Warburg Library has been packed and unpacked. First it was the private collection of Aby Warburg, later a public institution, originally in Hamburg and then in London from 1933 to the present. This essay also explores the various ways in which books have been — and continue to be — acquired by (...) the Warburg Library, including publication, donation, recommendation, and purchase. Each of these methods is not only discussed but also examined in light of Benjamin's account of the acquisition of his own library. Moreover, Benjamin's view that collections lose their meaning when they cease to be personal is challenged by the example of the Warburg Library, which has been transformed from a private collection containing around 15,000 books in 1911 to a public institution today housing over 350,000 volumes, while still maintaining its unique character.

The stresses of the twenty-first century have exposed the fault lines in Higher Education, both as an instructional space that facilitates student growth and as a social space that shapes our economic, political, and religious institutions. This book uses Paul Ricoeur’s rigorous writings to envision a Just University necessary for the years ahead.

Deep neural networks (DNNs) have had extraordinary successes in classifying photographic images of objects and are often described as the best models of biological vision. This conclusion is largely based on three sets of findings: (1) DNNs are more accurate than any other model in classifying images taken from various datasets, (2) DNNs do the best job in predicting the pattern of human errors in classifying objects taken from various behavioral datasets, and (3) DNNs do the best job in predicting (...) brain signals in response to images taken from various brain datasets (e.g., single cell responses or fMRI data). However, these behavioral and brain datasets do not test hypotheses regarding what features are contributing to good predictions and we show that the predictions may be mediated by DNNs that share little overlap with biological vision. More problematically, we show that DNNs account for almost no results from psychological research. This contradicts the common claim that DNNs are good, let alone the best, models of human object recognition. We argue that theorists interested in developing biologically plausible models of human vision need to direct their attention to explaining psychological findings. More generally, theorists need to build models that explain the results of experiments that manipulate independent variables designed to test hypotheses rather than compete on making the best predictions. We conclude by briefly summarizing various promising modeling approaches that focus on psychological data. (shrink)

Two experiments investigated the role that mental set plays in reading aloud using the task choice procedure developed by Besner and Care [Besner, D., & Care, S. . A paradigm for exploring what the mind does while deciding what it should do. Canadian Journal of Experimental Psychology, 57, 311–320]. Subjects were presented with a word, and asked to either read it aloud or decide whether it appeared in upper/lower case. Task information, in the form of a brief auditory cue, appeared (...) 750 ms before the word, or at the same time as the word. Experiment 1 yielded evidence consistent with the claim that at least some pre-lexical processing can be carried out in parallel with decoding the task cue . Experiment 2 provided evidence that such processing is restricted to pre-lexical levels . These data suggest that a task set is a necessary preliminary to lexical processing when reading aloud.

Public health ethics, like the field of public health it addresses, traditionally has focused more on practice and particular cases than on theory, with the result that some concepts, methods, and boundaries remain largely undefined. This paper attempts to provide a rough conceptual map of the terrain of public health ethics. We begin by briefly defining public health and identifying general features of the field that are particularly relevant for a discussion of public health ethics.Public health is primarily concerned with (...) the health of the entire population, rather than the health of individuals. Its features include an emphasis on the promotion of health and the prevention of disease and disability; the collection and use of epidemiological data, population surveillance, and other forms of empirical quantitative assessment; a recognition of the multidimensional nature of the determinants of health; and a focus on the complex interactions of many factors—biological, behavioral, social, and environmental—in developing effective interventions.

The cerebellum has been hypothesized to play a role in a variety of movement timing tasks that involve the processing of temporal information on a variety of timescales. Braitenberg, Heck & Sultan propose a new theory of cerebellar function that is able to account for movement timing on the order of a couple of hundred milliseconds. However, this theory does not account for the rôle the cerebellum plays in the acquisition and retention of adaptively timed discrete movements that are on (...) the order of 200 to 1000 milliseconds, and therefore does not account for the entire temporal range of cerebellar dependent processing.

On several key issues we agree with the commentators. Perhaps most importantly, everyone seems to agree that psychology has an important role to play in building better models of human vision, and (most) everyone agrees (including us) that deep neural networks (DNNs) will play an important role in modelling human vision going forward. But there are also disagreements about what models are for, how DNN–human correspondences should be evaluated, the value of alternative modelling approaches, and impact of marketing hype in (...) the literature. In our view, these latter issues are contributing to many unjustified claims regarding DNN–human correspondences in vision and other domains of cognition. We explore all these issues in this response. (shrink)

Although there is a long-standing international debate concerning the privatization and corporatization of health services, there has been relatively little systematic analysis of the ways these types of reform manifest. We examine the impact of privatization and corporatization on public hospitals, and in particular on hospitals’ autonomy and accountability, with two aims: to uncover the key themes in the literature, and to consider implementation issues. The review of 2,319 articles was conducted using content analysis and a discussion of selected key (...) issues. Several major themes appear in the privatization and corporatization literature, including their use as tools in health systems reform, and the role of governments in sponsoring the processes. We show that much of the underlying argument is ideological rather than evidence based. Those who promote versions of privatization or corporatization claim that decreased government involvement in the management of hospitals leads inter alia to benefits such as greater efficiency, better quality services, and increased choice for patients. Those who argue against say that increased privatization leads to deleterious outcomes such as decreased equity, compromised efficiency and poorer quality of care. The evidence is often weak and at times conflicting. Privatization and corporatization are difficult to implement, and at best produce mixed results, and their impact seems to depend more on the motivation of the evaluator than the standard of the results. These debates are of a type that is to a large extent only resolvable ideologically. (shrink)

Much progress has been made in recent years regarding the mechanisms of targeting of secretory proteins to, and across, the endoplasmic reticulum (ER) membrane. Many of the cellular components involved in mediating translocation across this bilayer have been identified and characterized. Polypeptide domains of secretory proteins, termed signal peptides, have been shown to be necessary, and in most cases sufficient, for entry of preproteins into the lumen of the ER. These NH2‐ terminal segments appear to serve multiple roles in targeting (...) and translocation. The structural features which mediate their multiple functions are currently the subject of intense study. (shrink)

The ability to extrapolate essential gist through the analysis and synthesis of information, prediction of potential outcomes, abstraction of ideas, and integration of relationships with world knowledge is critical for higher-order learning. The present study investigated the efficacy of cognitive training to elicit improvements in gist-reasoning and fact recall ability in 556 public middle-school students (grades seven and eight), versus a sample of 357 middle school students who served as a comparison group, to determine if changes in gist-reasoning and fact (...) recall were demonstrated without cognitive training. The results showed that, in general, cognitive training increased gist-reasoning and fact recall abilities in students from families in poverty as well as students from families living above poverty. However, the magnitude of gains in gist-reasoning varied as a function of gender and grade-level. Our primary findings were that seventh and eighth grade girls and eighth grade boys showed significant increases in gist-reasoning after training regardless of socioeconomic status. There were no significant increases in gist-reasoning or fact recall ability for the 357 middle school students who served in the comparison group. We postulate that cognitive training in middle school is efficacious for improving gist-reasoning ability and fact recall in students from all socioeconomic levels. (shrink)
