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)

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)

This intervention queries whether subjecting feminist jurisprudence to a methodological transfiguration toward pragrammatology (Derrida, in Smith and Kerrigan 1984) holds liberating potential for f (be it ‘woman’, ‘female’ or ‘feminine’) as both a signifier and a subject to be read with lucidity and nuance in feminist justice claims. I examine feminist jurisprudence’s methodological challenges in the settler colonial context of Alaska with respect to the murders of Della Brown (in 2000) and Mindy Schloss (in 2007). I advance my case for (...) pragrammatology as a critical methodology for feminist jurisprudence by subjecting the case(s) of Brown and Schloss to a more lucid (re)reading in two related and intersecting moves. First, I trace and deconstruct the citations of Brown and Schloss’ legal narratives to expose violence in the systemisation of f as a power and legal relation (Ahmed in Soc Legal Stud 4:55–73, 1995). I then examine the paradoxical nature of f justice claims which necessitate a pragrammatological approach. I conclude by advancing counsel on how we might move within paradox. (shrink)

Afferent feedback can appreciably alter the pharyngeal phase of swallow. In order to measure the stability of the swallow motor pattern during several types of alterations in afferent feedback, we assessed swallow during a conventional water challenge in four anesthetized cats, and compared that to swallows induced by fixed (20 Hz) and stochastic (1-20Hz) electrical stimulation applied to the superior laryngeal nerve. The swallow motor patterns were evaluated by electromyographic activity (EMG) of eight muscles, based on their functional significance: laryngeal (...) elevators (mylohyoid, geniohyoid, and thyrohyoid); laryngeal adductor (thyroarytenoid); inferior pharyngeal constrictor (thyropharyngeus); upper esophageal sphincter (cricopharyngeus); and inspiratory activity (parasternal and costal diaphragm). Both the fixed and stochastic electrical stimulation paradigms increased activity of the laryngeal elevators, produced short-term facilitation evidenced by increasing swallow durations over the stimulus period, and conversely inhibited swallow-related diaphragm activity. Both the fixed and stochastic stimulus conditions also increased specific EMG amplitudes, which never occurred with the water challenges. Stochastic stimulation increased swallow excitability, as measured by an increase in the number of swallows produced. Consistent with our previous results, changes in the swallow motor pattern for pairs of muscles were only sometimes correlated with each other. We conclude that alterations in afferent feedback produced particular variations of the swallow motor pattern. We hypothesize that specific SLN feedback might modulate the swallow central pattern generator during aberrant feeding conditions (food/liquid entering the airway), which may protect the airway and serve as potentially important clinical diagnostic indicators.

Let ΩΩ be the semigroup of all mappings of a countably infinite set Ω. If U and V are subsemigroups of ΩΩ, then we write U≈V if there exists a finite subset F of ΩΩ such that the subsemigroup generated by U and F equals that generated by V and F. The relative rank of U in ΩΩ is the least cardinality of a subset A of ΩΩ such that the union of U and A generates ΩΩ. In this paper (...) we study the notions of relative rank and the equivalence ≈ for semigroups of endomorphisms of binary relations on Ω.The semigroups of endomorphisms of preorders, bipartite graphs, and tolerances on Ω are shown to lie in two equivalence classes under ≈. Moreover such semigroups have relative rank 0, 1, 2, or in ΩΩ where is the minimum cardinality of a dominating family for . We give examples of preorders, bipartite graphs, and tolerances on Ω where the relative ranks of their endomorphism semigroups in ΩΩ are 0, 1, 2, and .We show that the endomorphism semigroups of graphs, in general, fall into at least four classes under ≈ and that there exist graphs where the relative rank of the endomorphism semigroup is 20.

This anthology contains ten selections on the philosophy of religion, all of which were written by English-speaking analytic philosophers. The opening selection contains the contributions of Antony Flew, R. M. Hare, and Basil Mitchell to the University discussion on theology and falsification. This first selection, written in 1951, establishes the basic problematic for the book, as indeed it has for much of the discussion of religion among analytic philosophers during the last twenty years. The next three chapters in the (...) book contain articles by I. M. Crombie, John Hick, and R. B. Braithwaite which further develop the question of the falsifiability of religious statements. These are followed by articles by J. L. Mackie and Alvin Plantinga which give contrary interpretations regarding the impact of the existence of evil upon the credibility of religious assertions. The remaining chapters contain discussions of religious belief by D. Z. Phillips and H. H. Price, and of the possibility of deciding the question of the existence of God by R. W. Hepburn and Terence Penelhum. The editor provides a helpful introduction which shows the relationships between the various articles and underscores the main contributions of each. The editor also provides a useful and ample bibliography of English-language books and articles on the philosophy of religion, most of them by analytic philosophers. The bibliography is arranged according to the subject-matter covered in the text. This is a representative and useful anthology of the analytic philosophy of religion. It makes clear what are the major questions which interest analytic philosophers of religion, what procedures these thinkers use to try to answer these questions, and what some of their answers are. The editor suggests that if there is a single lesson to be learned from his anthology, it is that the philosophy of religion demands both philosophical competence and a sympathetic understanding of the religious subject-matter. Another lesson one could easily draw from this collection is that the strength of analytic philosophy of religion lies in its logical exactitude and clarity of expression, while a major weakness is its neglect of the wealth of data regarding religion provided by phenomenology, the history of religions, and the social sciences.--H.

The Covid-19 pandemic has led to severe shortages of many essential goods and services, from hand sanitizers and N-95 masks to ICU beds and ventilators. Although rationing is not unprecedented, never before has the American public been faced with the prospect of having to ration medical goods and services on this scale.

Background: Decisions of patients, families, and health care providers about medical care at the end of life depend on many factors, including the societal culture. A pan-European study was conducted to determine the frequency and types of end of life practices in European intensive care units , including those in Israel. Several results of the Israeli subsample were different to those of the overall sample.Objective: The objective of this article was to explore these differences and provide a possible explanation based (...) on the impact of culture on end of life decision making.Method: All adult patients admitted consecutively to three Israeli ICUs who died or underwent any limitation of life saving interventions between 1 January 1999 and 30 June 2000 were studied prospectively . These patients were compared with a similar sample taken from the larger study carried out in 37 European ICUs. Patients were followed until discharge, death, or 2 months from the decision to limit therapy. End of life decisions were prospectively organised into one of five mutually exclusive categories: cardiopulmonary resuscitation , brain death, withholding treatment, withdrawing treatment, and active shortening of the dying process . The data also included patient characteristics , specific therapies limited, and the method of SDP.Results: The majority of patients had treatment withheld, none underwent SDP, 62 received CPR , 31 had brain death , and 18 underwent withdrawal of treatment . The primary reason given for limiting treatment was that the patient was unresponsive to therapy . End of life discussions were held with 132 families , the vast majority of which revolved around withholding treatment and the remainder concerned withdrawing treatment .There was a statistically significant association between the type of end of life decision and region—that is, the northern region of Europe, the central region, the southern region, and Israel.Conclusions: Regional culture plays an important part in end of life decision making. Differences relating to end of life decision making exist between regions and these differences can often be attributed to cultural factors. Such cultures not only affect patients and their families but also the health care workers who make and carry out such decisions. (shrink)

The idea of agent causation—that a system such as a living organism can be a cause of things in the world—is often seen as mysterious and deemed to be at odds with the physicalist thesis that is now commonly embraced in science and philosophy. Instead, the causal power of organisms is attributed to mechanistic components within the system or derived from the causal activity at the lowest level of physical description. In either case, the ‘agent’ itself (i.e., the system as (...) a whole) is left out of the picture entirely, and agent causation is explained away. We argue that this is not the right way to think about causation in biology or in systems more generally. We present a framework of eight criteria that we argue, collectively, describe a system that overcomes the challenges concerning agent causality in an entirely naturalistic and non-mysterious way. They are: (1) thermodynamic autonomy, (2) persistence, (3) endogenous activity, (4) holistic integration, (5) low-level indeterminacy, (6) multiple realisability, (7) historicity, (8) agent-level normativity. Each criterion is taken to be dimensional rather than categorical, and thus we conclude with a short discussion on how researchers working on quantifying agency may use this multidimensional framework to situate and guide their research.

Wernham's critical edition includes the complete text of the Tractatus Politicus and all the portions of the Tractatus Theologico-Politicus having to do with politics and ethics, with Latin and English texts conveniently printed face-à-face. The introduction and notes are balanced and substantial; they conclude from a detailed comparison of Spinoza's political thought with Hobbes' that Spinoza, while less "modern" in outlook than his English contemporary, may nevertheless possess greater relevance for current political philosophy.--J.

An analytical investigation into compressible gas flow with slight rarefactions through the insect trachea and tracheoles during the closed spiracle phase is undertaken, and a complete set of asymptotic analytical solutions is presented. We first obtain estimates of the Reynolds and Mach numbers at the channel terminal ends where the tracheoles directly deliver respiratory gases to the cells, by comparing the magnitude of the different forces in the compressible gas flow. The 2D Navier–Stokes equations with a slip boundary condition are (...) used to investigate compressibility and rarefied effects in the trachea and tracheoles. Expressions for the velocity components, pressure gradients and net flow inside the trachea are then presented. Numerical simulations of the tracheal compressible flow are performed to validate the analytical results from this study. This work extends previous work of Arkilic et al. :167–178, 1997) on compressible flows through a microchannel. Novel devices for microfluidic compressible flow transport may be invented from results obtained in this study. (shrink)

As the gap between the need for and supply of human organs continues to widen, the aim of securing additional sources of these “gifts of the body” has become a seemingly overriding moral imperative, one that could—and some argue, should—override the widespread ban on organ markets. As a medical practice, organ transplantation entails the inherent risk that one human being, a donor, will become little more than a means to the end of healing for another human being and that he (...) or she will come to have a purely instrumental value. With the establishment of organ markets, not only will the harms of instrumentalization be a reality—the ends of medicine will be further compromised and confused. (shrink)
