This investigation examined age-related differences in auditory-visual integration as reflected on perceptual judgments of temporally misaligned AV English sentences spoken by native English and native Spanish talkers. In the detection task, it was expected that slowed auditory temporal processing of older participants, relative to younger participants, would be manifest as a shift in the range over which participants would judge asynchronous stimuli as synchronous. The older participants were also expected to exhibit greater declines in speech recognition for asynchronous AV stimuli (...) than younger participants. Talker accent was hypothesized to influence listener performance, with older listeners exhibiting a greater narrowing of the AV simultaneity window and much poorer recognition of asynchronous AV foreign-accented speech compared to younger listeners. Participant groups included younger and older participants with normal hearing and older participants with hearing loss. Stimuli were video recordings of sentences produced by native English and native Spanish talkers. The video recordings were altered in 50 ms steps by delaying either the audio or video onset. Participants performed a detection task in which they judged whether the sentences were synchronous or asynchronous, and performed a recognition task for multiple synchronous and asynchronous conditions. Both the detection and recognition tasks were conducted at the individualized signal-to-noise ratio corresponding to approximately 70% correct speech recognition performance for synchronous AV sentences. Older listeners with and without hearing loss generally showed wider AV simultaneity windows than younger listeners, possibly reflecting slowed auditory temporal processing in auditory lead conditions and reduced sensitivity to asynchrony in auditory lag conditions. However, older and younger listeners were affected similarly by misalignment of auditory and visual signal onsets on the speech recognition task. This suggests that older listeners are negatively impacted by temporal misalignments for speech recognition, even when they do not notice that the stimuli are asynchronous. Overall, the findings show that when listener performance is equated for simultaneous AV speech signals, age effects are apparent in detection judgments but not in recognition of asynchronous speech.

The United States’ ambitious Precision Medicine Initiative proposes to accelerate exponentially the adoption of precision medicine, an approach to health care that tailors disease diagnosis, treatment, and prevention to individual variability in genes, environment, and lifestyle. It aims to achieve this by creating a cohort of volunteers for precision medicine research, accelerating biomedical research innovation, and adopting policies geared toward patients’ empowerment. As strategies to implement the PMI are formulated, critical consideration of the initiative's ethical and sociopolitical dimensions is needed. (...) Drawing on scholarship of nationalism and democracy, we discuss the PMI's construction of what we term “genomic citizenship”; the possible normative obligations arising therefrom; and the ethical, legal, and social challenges that will ensue. Although the PMI is a work in progress, discussion of the existing and emerging issues can facilitate the development of policies, structures, and procedures that can maximize the initiative's ability to produce equitable and socially sensitive outcomes. Our analysis can also be applied to other population-based, precision medicine research programs. (shrink)

Whole genome and exome sequencing techniques raise hope for a new scale of diagnosis, prevention, and prediction of genetic conditions, and improved care for children. For these hopes to materialize, extensive genomic research with children will be needed. However, the use of WGS/WES in pediatric research settings raises considerable challenges for families, researchers, and policy development. In particular, the possibility that these techniques will generate genetic findings unrelated to the primary goal of sequencing has stirred intense debate about whether, which, (...) how, and when these secondary or incidental findings should be returned to parents and minors. The debate is even more pronounced when the subjects are adolescents, for whom decisions about return of SFs may have particular implications. In this paper, we consider the rise of “genomic citizenship” and the main challenges that arise for these stakeholders: adolescents' involvement in decisions relating to return of genomic SFs, the types of SFs that should be offered, privacy protections, and communication between researchers and adolescents about SFs. We argue that adolescents' involvement in genomic SF-related decisions acknowledges their status as valuable stakeholders without detracting from broader familial interests, and promotes more informed genomic citizens.

Query processing in ground definite deductive is known to correspond precisely to a linear programming problem. However, the “groundedness” requirement is a huge drawback to using linear programming techniques for logic program computations because the ground version of a logic program can be very large when compared to the original program. Furthermore, when we move from propositional logic programs to first-order logic programs, this effectively means that functions symbols may not occur in clauses. In this paper, we develop a theory (...) of “instantiate- by-need” that performs instantiations only when needed. We prove that this method is sound and complete when computing answer substitutions for non-ground logic programs including those containing function symbols. More importantly, when taken in conjunction with Colmerauer's result that unification can be viewed as linear programming, this means that resolution with unification can be completely replaced by linear programming as an operational paradigm. Additionally, our tree construction method is not rigidly tied to the linear programming paradigm-we will show that given any method M that can compute the set of atomic logical consequences of a propositional logic program, our method can use M to compute , the set of all atoms that are consequences of a first-order logic program.

The study of paraconsistent logic as a branch of mathematics and logic has been pioneered by Newton da Costa. With the growing advent of distributed and often inconsistent databases over the last ten years, there has been growing interest in paraconsistency amongst researchers in databases and knowledge bases. In this paper, we provide a brief survey of work in paraconsistent databases and knowledge bases affected by Newton da Costa's important and lasting contributions to the field.

Although well established in developed countries, Ethics review boards in the academia, and specifically for social and behavioral sciences (SBS) research, is a relatively new, and still a controversy inducing endeavor. This study explores the establishment and functioning of ERBs in Israeli academia, serving as a case study for the challenges and progress made in ensuring ethical research practices in non-medical related spheres. A purposeful sample of 46 participants was selected, comprising ERB current or past members and SBS researchers, who (...) each interacted extensively with ERB’s evaluation processes. The participants came from all eight research universities of Israel, as well as seven large public and private academic colleges. Open, semi structured In-depth interviews were conducted in order to facilitate a critical reflective stance among the various participants, exploring their experiences, behaviors and the meanings they assign to ERB processes. Our research revealed two major themes. The first is the developmental trajectories in the construction processes of ERBs in Israel, comprised of the following stages: Initiation, expansion, opposition, and acceptance and assimilation. The second was a typology of participation throughout the ERBs’ construction process. Inspired by Merton’s strain theory, this typology includes conformists, ritualists, ideologists, control-freaks, and insurgents. The findings expose a unique perspective into the initiation, establishment, and development of ERBs, which can shed light on the role of ERBs in general, as well as point out how resistance to ERBs, as well as the different reasons for championing them, affected not only ERBs form and their legitimacy, but also their interaction with researchers.

This paper offers a theoretical discussion on why the nursing profession has had a delayed response to the issue of climate change. We suggest this delay may have been influenced by the early days of nursing's professionalization. Specifically, we examine nursing's professional mandate, the generally accepted metaparadigm, and the grand theorists’ conceptualizations of both the environment and the nurse–environment relationship. We conclude that these works may have encouraged nurses to conceptualize the environment, as well as their relationship with it, mainly (...) in terms of the individual patient, and as such, nurses have not been encouraged to understand these concepts from a broader perspective. By not having the philosophical and theoretical foundations to understand the environment in relation to society, it is not surprising that nurses have had a delayed response to climate change and may not have viewed it as a professional concern. A planetary health perspective is suggested as a theoretical basis for nursing education, research and practice. Taking on a planetary health perspective could help nurses progress the profession and move healthcare systems towards supporting a climate‐resilient future. (shrink)

This article considers the issue of racial difference in the Goddess movement, using the mythological figure of Arachne, a skilful weaver whom the goddess Athena transformed into a spider, to explore the unequal relational dynamics between white Goddess feminists and women of colour.

Ultimately, I argue that feminist spirituality must recognize and address structural inequality between white women and women of colour, or in other words, listen to Arachne’s voice. (shrink)

In recent years, Cesar Chavez’s life and legacy have been subjected to increased scrutiny. The ensuing reevaluations of Chavez, wittingly or not, are matters of ethical, as well as historical and biographical, concern. This article has two aims. First, it reconstructs Chavez’s account of exemplarity and uses it to assess his legacy. Second, it provides an account of exemplarity situated within social practices. As I argue, exemplarity operates through social practices, rather than mystically as posited by a contagion model. The (...) end result is an ethically nuanced reassessment of Chavez and an account of exemplarity that includes its social dimension. (shrink)

In this article I argue that the Critical Kant endorses the claim that God creates the best possible world, and that this claim is best understood as committing him to the view that God creates an infinitely valuable world. Kant’s understudied Critical theory of the best possible world differs significantly from his better-known quasi-Leibnizian pre-Critical account insofar as it uses an axiological rather than ontological metric for the goodness of worlds. The axiological metric introduces unique challenges for a Kantian account (...) of the best possible world. These challenges are in turn resolved via an infinite value interpretation. (shrink)

With twentieth- and twenty-first-century philosophy of science’s unfolding acceptance of the nature of scientific inquiry being value-laden, the persistent worry has been that there are no means for legitimate negotiation of the social or non-epistemic values that enter into science. The rejection of the value-free ideal in science has thereby been coupled with the spectres of indiscriminate relativism and bias in scientific inquiry. I challenge this view in the context of recently expressed concerns regarding Canada's death of evidence controversy. The (...) worry, raised by Stathis Psillos, is that as constructivist accounts of science demoted the previously secure status of evidence for drawing justified conclusions in science, we were left with no rational delineation between the right and wrong values for science. The implication for the death of evidence controversy is that we may have no rational grounds for claiming that the Canadian Government is wrong to interfere with scientific enterprise. But he does offer another avenue for reaching the conclusion that the wrong social values are directing the current stifling of some sectors of Canadian science. Psillos draws from standpoint epistemologies to devise a salient defence of ‘valuing evidence’ as a universalizable social value. That is, government bodies ought to enable scientific research via adequate funding as well as political non-interference. In this paper, I counter that non-epistemic values can be rationally evaluated and that standpoint epistemology’s universalizable standpoint provides an inadequate framework for negotiating social values in science. Regarding, I draw from the evidence-based medicine debate in philosophy of medicine and from feminist empiricist investigations into the science–values relationship in order to make the argument for empirically driven value arbitration. If social values can be rationally chosen in the context of justification, then we can have grounds for charging the Canadian leadership with being ‘at war with science’. I further argue that my recommended empiricist methodology is preferable to Psillos’s search for universalizable perspectives for negotiating social values in science because the latter method permits little more than the trivial conclusion that evidence is valuable to science.

In recent years, new forms of high-tech controlled environment agriculture (CEA) have received increased attention and investment. These systems integrate a suite of technologies – including automation, LED lighting, vertical plant stacking, and hydroponic fertilization – to allow for greater control of temperature, humidity, carbon dioxide, oxygen, and light in an enclosed growing environment. Proponents insist that CEA can produce sustainable, nutritious, and tasty local food, particularly for the cities of the future. At the same time, a variety of critics (...) raise concerns about its environmental impacts and energy use, high startup costs, and consumer accessibility challenges, among other issues. At this stage, however, relatively little research has explored actual consumer knowledge and attitudes related to CEA processes and products. Guided by theories of sense-making, this article draws from structured interviews with local food consumers in New York City to examine what people know and think about high-tech CEA. From there, it explores the extent to which CEA fits into consumer conceptualizations of what makes for “good food.” Key findings emphasize that significant gaps in public understanding of CEA remain, that CEA products’ success will depend on the ability of the industry to deliver on its environmental promises, and that concerns about “unnatural” aspects of CEA will need to be allayed. Given the price premium at which high-tech CEA products are currently sold, the industry’s expansion will depend in large part on its ability to convince value-oriented food consumers that the products meet the triple-bottom-line of economic, social, and environmental sustainability goals.

Because “evidence” is at issue in evidence-based medicine (EBM), the critical responses to the movement have taken up themes from post-positivist philosophy of science to demonstrate the untenability of the objectivist account of evidence. While these post-positivist critiques seem largely correct, I propose that when they focus their analyses on what counts as evidence, the critics miss important and desirable pragmatic features of the evidence-based approach. This article redirects critical attention toward EBM’s rigid hierarchy of evidence as the culprit of (...) its objectionable epistemic practices. It reframes the EBM discourse in light of a distinction between objectivist and pragmatic epistemology, which allows for a more nuanced analysis of EBM than previously offered: one that is not either/or in its evaluation of the decision-making technology as either iconoclastic or creedal. -/- .

This paper examines the conclusions that one must draw from the finding that there are values in science. The value-ladenness of scientific claims puts the nature and role of empirical evidence into question, as seen in recent discussions in the philosophy of medicine regarding evidence-based medicine and feminist science studies, which maintains the normativity of its feminist claims. Within the critical literature and debates surrounding evidence-based medicine (EBM), one finds a championing of the lessons learned from post-positivist science studies: the (...) evidence-based effort to ground medical decision-making in the most rigorous sources of scientific evidence obscures the social values that necessarily enter into all decision-making contexts, the complex social context of clinical practice being no exception. The critics of EBM claim that to try to derive a formal methodology governed by pre-established rules, guidelines, and hierarchies of information misplaces the contextual and social features of biomedical knowledge and practice, thereby obscuring the power interests that so problematically dictate large factions of biomedical research and practice. Yet possible relativist implications follow from this finding, and we find that the EBM critics amply criticize EBM’s tacit theory of evidence, but then fail to formulate a constructive alternative theory of evidence within this fact-value interplay. After overviewing some such criticisms of evidence-based medicine, I turn to contemporary critical science studies, especially the feminist empiricism of Lynn Hankinson Nelson and Helen Longino, for workable alternative theories of evidence within a framework of normative scientific claims. I will suggest these theories fail to guide medical decision-making because of some undesirable consequences of Quinean fact-value holism: the denial that our values have logical content and are therefore not empirically examinable relativises even these nuanced conceptions of evidence. A naturalized look at how facts and values actually interact in medical decision-making suggests that this fact/value holism is not realistic. I provide an illustrative example of a physician devising a treatment recommendation for a patient to demonstrate that in practice, facts and values intermingle in the decision-making process without indeterminacy and subsequent appeals to moral and political frameworks, as feminist empiricism suggests. In the end, value-laden evidence can retain its adjudicative force and normativity. (shrink)

We live in an era characterized by technology as an integral part of the overall experiences. Non-hierarchic access to communication and virtual contacts in the metaverse, experienced as no less real than those in the brick-and-mortar world.

The social distancing (...) regulations imposed worldwide provided educators with an opportunity to try out a variety of technological tools that enable surprising collaborations and access to information that encourages cognitive flexibility and a reexamination of our assumptions on knowledge, learning, teaching, human interaction, and space-time’s limitations.

Abstract:This article recovers a submerged philosophical debate between Bertrand Russell's theory of descriptions and T. S. Eliot's "Love Song of J. Alfred Prufrock." Russell's concern with immediate experience ("acquaintance") underscores a dilemma troubling literary modernism generally and modernist abstraction in particular. In "Prufrock," acquaintance with reality marks an epistemic failure whose social form is the "etherization" gripping the city and everything in it. The conversation between Russell's philosophy and Eliot's poetry is grounded in but exceeds the men's real-life acquaintance. Rather (...) than influence, at stake is a circulation of ideas between philosophy and modernist poetry and the questions of knowledge raised by both. (shrink)

Resemblances obtain not only between objects but between properties. Resemblances of the latter sort - in particular resemblances between quantitative properties - prove to be the downfall of a well-known theory of universals, namely the one presented by David Armstrong. This paper examines Armstrong's efforts to account for such resemblances within the framework of his theory and also explores several extensions of that theory. All of them fail.

Since the inception of large‐scale human genome research, there has been much caution about the risks of exacerbating a number of socially dangerous attitudes linked to human genetics. These attitudes are usually labeled with one of a family of genetic or genomic “isms” or “ations” such as “genetic essentialism,” “genetic determinism,” “genetic reductionism,” “geneticization,” “genetic stigmatization,” and “genetic discrimination.” The psychosocial processes these terms refer to are taken to exacerbate several ills that are similarly labeled, from medical racism and psychological (...) fatalism to economic exploitation and social exclusion. But as genomic information becomes more familiar in clinical and research settings as well as other life activities, do we need to continue to worry so much about this family of attitudes and their impact on existing problems?In genomics, the underlying anxiety has been that disclosure of genomic information will trigger a series of (seemingly unavoidable) negative responses that will affect individuals, their families, and their communities at large. The fundamental social challenges that hyperbolic genomic messaging, low genomic literacy, and “folk biology” help sustain remain to be addressed. If we hope to break the cycle of genomic isms and ations, we will have to get better at resisting overinterpretations of the relevance that genomics has for people’s future potentials, ancestral vulnerabilities, community memberships, and ethnic affiliations.

The bioethics literature has paid little attention to matters of informed reproductive decision-making among women of childbearing age who have chronic kidney disease (CKD), including women who are on dialysis or women who have had a kidney transplant. Women with CKD receive inconsistent and, sometimes, inadequate reproductive counseling, particularly with respect to information about pursuing pregnancy. We identify four factors that might contribute to inadequate and inconsistent reproductive counseling. We argue that women with CKD should receive comprehensive reproductive counseling, including (...) information about the possibility of pursuing pregnancy, and that more rigorous research on pregnancy in women with CKD, including women on dialysis or who have received a kidney transplant, is warranted to improve informed reproductive decision making in this population.

While most of healthcare research and practice fully endorses evidence-based healthcare, a minority view borrows popular themes from philosophy of science like underdetermination and value-ladenness to question the legitimacy of the evidence-based movement’s philosophical underpinnings. While the feminist origins go unacknowledged, those critics adopt a feminist reading of the “gap argument” to challenge the perceived objectivism of evidence-based practice. From there, the critics seem to despair over the “subjective elements” that values introduce to clinical reasoning, demonstrating that they do not (...) subscribe to feminist science studies’ normative program——where contextual values can enable good science and justified decisions. In this paper, I investigate why it is that the critics of evidence-based medicine adopt feminist science’s characterization of the problem but resist the productive solutions offered by those same theorists. I suggest that the common feminist empiricist appeal to idealized epistemic communities is impractical for those working within the current biomedical context and instead offer an alternate stream of feminist research into the empirical content of values (found in the work of Elizabeth Anderson and Sharyn Clough) as a more helpful recourse for facilitating the important task of legitimate and justified clinical decision-making. I use a case study on clinical decision-making to illustrate the fruitfulness of the latter feminist empiricist framework. -/- See response by Sharyn Clough: http://wp.me/p1Bfg0-1aN See reply by Maya Goldenberg: http://wp.me/p1Bfg0-1oY.

Intelligible speakers achieve specific vocal tract constrictions in rapid sequence. These constrictions are associated in theory with speech motor goals. Adult-focused models of speech production assume that discrete phonological representations, sequenced into word-length plans for output, define these goals. This assumption introduces a serial order problem for speech. It is also at odds with children's speech. In particular, child phonology and timing control suggest holistic speech plans, and so the hypothesis of whole word production. This hypothesis solves the serial order (...) problem by avoiding it. When the same solution is applied to adult speech the problem becomes how to explain the development of highly intelligible speech. This is the problem addressed here. A modeling approach is used to demonstrate how perceptual-motor units of production emerge over developmental time with the perceptual-motor integration of holistic speech plans that are also phonological representations; the specific argument is that perceptual-motor units are a product of trajectories (nearly) crossing in motor space. The model, which focuses on the integration process, defines the perceptual-motor map as a set of linked pairs of experienced perceptual and motor trajectories. The trajectories are time-based excursions through speaker-defined perceptual and motor spaces. By hypothesis, junctures appear where motor trajectories near or overlap one another in motor space when the shared (or extremely similar) articulatory configurations in these regions are exploited to combine perceptually-linked motor paths along different trajectories. Junctures form in clusters in motor space. These clusters, along with their corresponding (linked) perceptual points, represent perceptual-motor units of production, albeit at the level of speech motor control only. The units serve as pivots in motor space during speaking; they are points of transition from one motor trajectory to another along perceptually-linked paths that are selected to produce best approximations of whole word targets.
