Canadian and American population-based research concerning sexual and/or gender minority populations provides evidence of persistent breast and gynecologic cancer-related health disparities and knowledge divides. The Cancer's Margins research investigates the complex intersections of sexual and/or gender marginality and incommensurabilities and improvisation in engagements with biographical and biomedical cancer knowledge. The study examines how sexuality and gender are intersectionally constitutive of complex biopolitical mappings of cancer health knowledge that shape knowledge access and its mobilization in health and treatment decision-making. Interviews were (...) conducted with a diverse group of sexual and/or gender minority breast or gynecologic cancer patients. The LGBQ//T2 cancer patient narratives we have analyzed document in fine grain detail how it is that sexual and/or gender minority cancer patients punctuate the otherwise lockstep assemblage of their cancer treatment decision-making with a persistent engagement in creative attempts to resist, thwart and otherwise manage the possibility of discrimination and likewise, the probability of institutional erasure in care settings. Our findings illustrate the demands that cancer places on LGBQ//T2 patients to choreograph access to, and mobilization of knowledge and care, across significantly distinct and sometimes incommensurable systems of knowledge.

Exceptionally preserved fossils are the product of complex interplays of biological and geological processes including burial, autolysis and microbial decay, authigenic mineralization, diagenesis, metamorphism, and finally weathering and exhumation. Determining which tissues are preserved and how biases affect their preservation pathways is important for interpreting fossils in phylogenetic, ecological, and evolutionary frameworks. Although laboratory decay experiments reveal important aspects of fossilization, applying the results directly to the interpretation of exceptionally preserved fossils may overlook the impact of other key processes that (...) remove or preserve morphological information. Investigations of fossils preserving non-biomineralized tissues suggest that certain structures that are decay resistant are rarely preserved, and decay-prone structures can fossilize, albeit rarely. As we review here, decay resistance is an imperfect indicator of fossilization potential, and a suite of biological and geological processes account for the features preserved in exceptional fossils. Organisms decayed experimentally in seawater have been used as direct analogs for soft-bodied fossil taxa, with fossils representing a snapshot of a particular stage of decay. We argue that numerous geological and biological processes account for fossilization and that all of these should be considered when reconstructing extinct organisms. (shrink)

Recent advances in wireless data transmission technology have the potential to revolutionize clinical neuroscience. Today sensing-capable electrical stimulators, known as “bidirectional devices”, are used to acquire chronic brain activity from humans in natural environments. However, with wireless transmission come potential failures in data transmission, and not all available devices correctly account for missing data or provide precise timing for when data losses occur. Our inability to precisely reconstruct time-domain neural signals makes it difficult to apply subsequent neural signal processing techniques (...) and analyses. Here, our goal was to accurately reconstruct time-domain neural signals impacted by data loss during wireless transmission. Towards this end, we developed a method termed Periodic Estimation of Lost Packets. PELP leverages the highly periodic nature of stimulation artifacts to precisely determine when data losses occur. Using simulated stimulation waveforms added to human EEG data, we show that PELP is robust to a range of stimulation waveforms and noise characteristics. Then, we applied PELP to local field potential recordings collected using an implantable, bidirectional DBS platform operating at various telemetry bandwidths. By effectively accounting for the timing of missing data, PELP enables the analysis of neural time series data collected via wireless transmission—a prerequisite for better understanding the brain-behavior relationships underlying neurological and psychiatric disorders.

Using covariant derivatives and the operator definitions of quantum mechanics, gauge invariant Proca and Lehnert equations are derived and the Lorenz condition is eliminated in U(1) invariant electrodynamics. It is shown that the structure of the gauge invariant Lehnert equation is the same in an O(3) invariant theory of electrodynamics.

ObjectiveTo further delineate risk and resilience factors contributing to trajectories of mental health symptoms experienced by college students through the pandemic.Participantsn = 183 college students.MethodsLinear mixed models examined time effects on depression and anxiety. Propensity-matched subgroups exhibiting “increased” versus “low and stable” depression symptoms from before to after the pandemic-onset were compared on pre-pandemic demographic and psychological factors and COVID-related experiences and coping strategies.ResultsStudents experienced worsening of mental health symptoms throughout the pandemic, particularly during Fall 2020 compared with Fall 2019. (...) The propensity-matched subgroup exhibiting relative resilience reported less alcohol use prior to the pandemic, greater use of active coping strategies, and less of an impact on their college progress.ConclusionsResults point to several potential targets of screening and intervention to decrease residual impacts of the pandemic.

Drawing on a landscape analysis of existing data-sharing initiatives, in-depth interviews with expert stakeholders, and public deliberations with community advisory panels across the U.S., we describe features of the evolving medical information commons. We identify participant-centricity and trustworthiness as the most important features of an MIC and discuss the implications for those seeking to create a sustainable, useful, and widely available collection of linked resources for research and other purposes.

M. Oaksford and N. Chater presented a Bayesian analysis of the Wason selection task in which they proposed that people choose cards in order to maximize expected information gain as measured by reduction in uncertainty in the Shannon-Weaver information theory sense. It is argued that the EIG measure is both psychologically implausible and normatively inadequate as a measure of epistemic utility. The article is also concerned with the descriptive account of findings in the selection task literature offered by Oaksford and (...) Chater. First, it is shown that their analysis data reported in the recent article of K. N. Kirby is unsound; second, an EIG analysis is presented of the experiments of P. Pollard and J. St. B. T. Evans that provides a strong empirical disconfirmation of the theory. (shrink)

This volume is a state-of-the-art survey of the psychology of reasoning, based around, and in tribute to, one of the field "s most eminent figures: Jonathan St B.T. Evans.

This collection by a distinguished group of philosophers, psychologists, and physiologists reflects an interdisciplinary approach to the central question of cognitive science: how do we model the mind? Among the topics explored are the relationships (theoretical, reductive, and explanatory) between philosophy, psychology, computer science, and physiology; what should be asked of models in science generally, and in cognitive science in particular; whether theoretical models must make essential reference to objects in the environment; whether there are human competences that are resistant, (...) in principle, to modelling; whether simulated thinking and intentionality are really thinking and intentionality; how semantics can be generated from syntactics; the meaning of the terms "representations" and "modelling;" whether the nature of the "hardware" matters; and whether computer models of humans are "dehumanizing." Contributors include Donald Davidson, Daniel C. Dennett, Margaret A. Boden, Adam Morton, Dennis Noble, T. Poggio, Colin Blakemore, K.V. Wilkes, P.N. Johnson-Laird, and Jonathan St. B.T. Evans.

[About the book]: This volume is a state-of-the-art survey of the psychology of reasoning, based around, and in tribute to, one of the field's most eminent figures: Jonathan St B.T. Evans.In this collection of cutting edge research, Evans' collaborators and colleagues review a wide range of important and developing areas of inquiry. These include biases in thinking, probabilistic and causal reasoning, people's use of 'if' sentences in arguments, the dual-process theory of thought, and the nature of human rationality. (...) These foundational issues are examined from various angles and finally integrated in a concluding panoramic chapter written by Evans himself.The eighteen chapters, all written by leading international researchers, combine state-of the-art research with investigation into the most fundamental questions surrounding human mental life, such as:What is the architecture of the human mind?Are humans rational, and what is the nature of this rationality?How do we think hypothetically? The Science of Reason offer s a unique combination of breadth, depth and integrative vision, making it an indispensable resource for researchers and students of human reason. (shrink)

A study is reported which focused on the problem-solving strategies employed by expert electronics engineers pursuing a real-world task: integrated-circuit design. Verbal protocol data were analysed so as to reveal aspects of the organisation and sequencing of ongoing design activity. These analyses indicated that the designers were implementing a highly systematic solution-development strategy which deviated only a small degree from a normatively optimal top-down and breadth-first method. Although some of the observed deviation could be described as opportunistic in nature, much (...) of it reflected the rapid depth-first exploration of tentative solution ideas. We argue that switches from a predominantly breadth-first mode of problem solving to depth-first or opportunistic modes may be an important aspect of the expert's strategic knowledge about how to conduct the design process effectively when faced with difficulties, uncertainties, and design impasses.

This monograph attempts to clarify one significant but much neglected aspect of Peirce's contribution to the philosophy of science. It was written in 1963 as my M. A. thesis at the Uni versity of Illinois. Since the topic is still neglected it is hoped that its pUblication will be of use to Peirce scholars. I should like to acknowledge my indebtedness to Dr. Max Fisch who broached this topic to me and who advised me con tinuously through its development, assisting (...) generously with his own insights and unpublished Peirce manuscripts.

This book explores the idea that we have two minds - automatic, unconscious, and fast, the other controlled, conscious, and slow. In recent years there has been great interest in so-called dual-process theories of reasoning and rationality. According to such theories, there are two distinct systems underlying human reasoning - an evolutionarily old system that is associative, automatic, unconscious, parallel, and fast, and a more recent, distinctively human system that is rule-based, controlled, conscious, serial, and slow. Within the former, processes (...) the former, processes are held to be innate and to use heuristics that evolved to solve specific adaptive problems. In the latter, processes are taken to be learned, flexible, and responsive to rational norms. -/- Despite the attention these theories are attracting, there is still poor communication between dual-process theorists themselves, and the substantial bodies of work on dual processes in cognitive psychology and social psychology remain isolated from each other. This book brings together leading researchers on dual processes to summarize the state-of-the-art, highlight key issues, present different perspectives, explore implications, and provide a stimulus to further work. It includes new ideas about the human mind both by contemporary philosophers interested in broad theoretical questions about mental architecture and by psychologists specialising in traditionally distinct and isolated fields. For all those in the cognitive sciences, this is a book that will advance dual-process theorizing, promote interdisciplinary communication, and encourage further applications of dual-process approaches.

Habermas's paradigm of communicative action is usually taken to be pretty much dominated by consensus, "Yes-saying." What if this were a radically one-sided perception? We take up this unorthodox position by arguing that "no-saying" in this paradigm is typically overlooked and underemphasized. To demonstrate this, we consider how negativity is figured at the most basic onto-ethical level in communicative action, as well as expressed in civil disobedience, a phenomenon to which Habermas assigns the remarkable role of "touchstone" (Prufstein) of constitutional (...) democracy. Once the importance of no-saying is drawn out, the paradigm looks distinctly less hostile to dissensus and agonism in democratic life. (shrink)

J. L. Austin (1911-1960) exercised in Post-war Oxford an intellectual authority similar to that of Wittgenstein in Cambridge. Although he completed no books of his own and published only seven papers, Austin became through lectures and talks one of the acknowledged leaders in what is called ‘Oxford philosophy’ or ‘ordinary language philosophy’. Few would dispute that among analytic philosophers Austin stands out as a great and original philosophical genius. Three volumes of his writing, published after his death, have become classics (...) in analytical philosophy: Philosophical Papers ; Sense and Sensibilia ; and How to Do Things with Words . First published in 1969, this book is a collection of critical essays on Austin’s philosophy written by well-known philosophers, many of whom knew Austin personally. A number of essays included were especially written for this volume, but the majority have appeared previously in various journals or books, not all easy to obtain. (shrink)

Causal and predictive learning research often employs intuitive and familiar hypothetical scenarios to facilitate learning novel relationships. The allergist task, in which participants are asked to diagnose the allergies of a fictitious patient, is one example of this. In such studies, it is common practice to ask participants to ignore their existing knowledge of the scenario and make judgments based only on the relationships presented within the experiment. Causal judgments appear to be sensitive to instructions that modify assumptions about the (...) scenario. However, the extent to which prior knowledge continues to affect competition for associative learning, even after participants are instructed to disregard it, is unknown. To answer this, we created a cue competition design that capitalized on prevailing beliefs about the allergenic properties of various foods. High and low allergenic foods were paired with foods moderately associated with allergy to create two compounds; high + moderate and low + moderate. We expected high allergenic foods to produce greater competition for associative memory than low allergenic foods. High allergenic foods may affect learning either because they generate a strong memory of allergy or because they are more salient in the context of the task. We therefore also manipulated the consistency of the high allergenic cue-outcome relationship with prior beliefs about the nature of the allergies. A high allergenic food that is paired with an inconsistent allergenic outcome should generate more prediction error and thus more competition for learning, than one that is consistent with prior beliefs. Participants were instructed to either use or ignore their knowledge of food allergies to complete the task. We found that while participants were able to set aside their prior knowledge when making causal judgments about the foods in question, associative memory was weaker for the cues paired with highly allergenic foods than cues paired with low allergenic foods regardless of instructions. The consistency manipulation had little effect on this result, suggesting that the effects in associative memory are most likely driven by selective attention to highly allergenic cues. This has implications for theories of causal learning as well as the way causal learning tasks are designed. (shrink)
