Despite the lack of invariance problem (the many‐to‐many mapping between acoustics and percepts), human listeners experience phonetic constancy and typically perceive what a speaker intends. Most models of human speech recognition (HSR) have side‐stepped this problem, working with abstract, idealized inputs and deferring the challenge of working with real speech. In contrast, carefully engineered deep learning networks allow robust, real‐world automatic speech recognition (ASR). However, the complexities of deep learning architectures and training regimens make it difficult to use them to (...) provide direct insights into mechanisms that may support HSR. In this brief article, we report preliminary results from a two‐layer network that borrows one element from ASR, long short‐term memory nodes, which provide dynamic memory for a range of temporal spans. This allows the model to learn to map real speech from multiple talkers to semantic targets with high accuracy, with human‐like timecourse of lexical access and phonological competition. Internal representations emerge that resemble phonetically organized responses in human superior temporal gyrus, suggesting that the model develops a distributed phonological code despite no explicit training on phonetic or phonemic targets. The ability to work with real speech is a major advance for cognitive models of HSR. (shrink)

This thought-provoking book examines the science behind human attractiveness—the ratios, proportions, and other factors that to a large extent dictate what we find "beautiful." It's said that "beauty is in the eye of the beholder," but recent scientific research suggests that human attractiveness is much more objective than we once thought, deeply rooted in our biology and evolutionary history. For instance, facial symmetry is considered extremely attractive because it indicates good health and nutrition during the formative developmental years. This book (...) explores these insights. Part I of The Biology of Beauty: The Science behind Human Attractiveness takes a closer look at what traits we find the most alluring and why. It discusses why attractiveness is important from an evolutionary standpoint and the advantages (and disadvantages) of being attractive. In addition to exploring these beauty "universals," it examines how beauty ideals can be shaped by factors such as culture, religion, and the media. Part II provides an in-depth analysis of individual features that contribute to attractiveness, offering scientific explanations for our preferences. The book also includes a collection of insightful sidebars that highlight beauty ideals in different parts of the world and at other times in history. (shrink)

This study examines the public's and physicians' willingness to support deception of insurance companies in order to obtain necessary healthcare services and how this support varies based on perceptions of physicians' time pressures. Based on surveys of 700 prospective jurors and 1617 physicians, the public was more than twice as likely as physicians to sanction deception (26% versus 11%) and half as likely to believe that physicians have adequate time to appeal coverage decisions (22% versus 59%). The odds of public (...) support for deception compared to that of physicians rose from 2.48 to 4.64 after controlling for differences in time perception. These findings highlight the ethical challenge facing physicians and patients in balancing patient advocacy with honesty in the setting of limited societal resources. (shrink)

A first-person account of some victims of the virus, the author puts faces and circumstances to the tragedy of the Covid-19 pandemic. Told from a chaplain’s point of view, these narratives will take the reader beyond the numbers and ask questions like: What is the cost of keeping families separated at the end of life, and, if patient/family centered care is so central to healthcare these days, why was it immediately discarded? Is potentially saving human lives worth the risk of (...) damaging them beyond repair? (shrink)

_Discourse, Dialogue and Technology Enhanced Learning_ is invaluable to all those wanting to explore how dialogic processes work and how we facilitate them. Dialogue is an important learning tool and it is by understanding how language affects us and how we use language to encourage, empathise, inquire, argue and persuade that we come closer to understanding processes of change in ourselves and our society. Most researchers in Education will find themselves interpreting some form of data in the form of words; (...) whether these words be explanations, conversations, narrations, reflections, debates or interviews and whether they are conducted through digital media or face-to-face. Discourse, textual or spoken, is therefore central to researching education. Each chapter focuses on the ways in which alternative levels of discourse analysis provide tools for the researcher, enabling insights into the way language works in learning, teaching practice and wider society. Drawing on the author’s own ‘DISCOUNT’ discourse analysis coding scheme and including a wide range of dialogue examples, this book covers: Why Dialogue? The Role of Dialogue in Education. Debate: Learning to Argue and Arguing to Learn Towards Meaning-Making: Inquiry, Narrative and Experience The Role of the Significant Other: Facilitation, Scaffolding and Mediation Inclusion, Collaboration and Community Media, Mode and Digital Literacy Researching Voices and Texts Discourse, Dialogue and Technology Enhanced Learning will be an essential resource for all students, educators and educational researchers who have an interest in the role of discourse in educational contexts.

The idea of a profound urban–rural divide has shaped analysis of the 2016 U.S. presidential election results. Here, through examples from agri-food systems, we consider the limitations of the urban–rural divide framework in light of the assumptions and intentions that underpin it. We explore the ideas and imaginaries that shape urban and rural categories, consider how material realities are and are not translated into U.S. rural development, farm, and nutrition policies, and examine the blending of rural and urban identities through (...) processes of rural deagrarianization and urban reagrarianization. We do not argue that an urban–rural divide does not exist, as studies and public opinion polls illustrate both measured and perceived differences in many aspects of the lived experiences that shape our individual and collective actions. Ultimately, we suggest that the urban–rural divide concept obscures the diversity and dynamism of experiences each category encompasses. Additionally, it ignores the connections and commonalities that demand integrative solutions to challenges in agri-food systems, and draw attention to the power relations that shape resource access and use within and across urban and rural spaces.

Perceived control in contingency learning is linked to psychological wellbeing with low levels of perceived control thought to be a cause or consequence of depression and high levels of control considered to be the hallmark of mental healthiness. However, it is not clear whether this is a universal phenomenon or whether the value that people ascribe to control influences these relationships. Here we hypothesize that values affect learning about control contingencies and influence the relationship between perceived control and symptoms of (...) mood disorders. We tested these hypotheses with European university samples who were categorized as endorsing (or not) values relevant to control - individualist and collectivist values. Three online experimental contingency learning studies (N1 = 127, N2 = 324, N3 = 272) were carried out. Evidence suggested that individualist values influenced basic learning processes via an effect on learning about the context in which events took place. Participants who endorsed individualist values made control judgments that were more in line with an elemental associative learning model, whilst those who were ambivalent about individualist values made judgments that were more consistent with a configural process. High levels of perceived control and individualist values were directly associated with increased euphoric symptoms of bipolar disorder, and such values completely mediated the relation between perceived control and symptoms. The effect of low perceived control on depression was moderated by collectivist values. Anxiety created by dissonance between values and task may be a catalyst for developing mood symptoms. Conclusions are that values play a significant intermediary role in the relation between perceived control and symptoms of mood disturbance. (shrink)

CRISPR, a recently developed gene-editing tool, has become synonymous with rapid biological advancement. While gene editing had been performed in life sciences research for decades, genetic engineering with CRISPR is much more straightforward, faster, and less expensive—and thus, the technology has been rapidly democratized. CRISPR was built on a natural mechanism, the method by which bacteria resist infections from viruses called bacteriophage. Once infected, bacteria may recognize specific genetic sequences of the invading bacteriophage virus and chop its genetic material into (...) pieces. This bacterial immune response, discovered through basic research, has been exploited by scientists to develop a gene-editing tool... (shrink)

While a number of valid molecular targets have been discovered for tumours over the past decade, finding an effective way of delivering therapeutic genes specifically to tumours has proved more problematic. A variety of viral and non‐viral delivery vehicles have been developed and applied in anti‐cancer gene therapies. However, these suffer from either inefficient and/or short‐lived gene transfer to target cells, instability in the bloodstream and inadequate tumour targeting. Recently, various types of non‐pathogenic obligate anaerobic and facultative anaerobic bacteria have (...) been shown to infiltrate and selectively replicate within solid tumours when delivered systemically. This has prompted the development of cancer gene therapy protocols that use such bacteria as gene delivery vehicles. Here, we review the evidence for the success of these in pre‐clinical models and clinical trials, as single modality treatments and in combination with conventional cancer therapies.

Liberalism, in any of its forms, places a strong emphasis on the individual---it prioritizes equal rights and liberties, and measures are taken to assure for all citizens the opportunity to make full use of their freedoms and entitlements. Many conceptions of human rights are objected to on the grounds that they are based on liberal premises, and insufficiently sensitive to the fact of reasonable cultural pluralism. ;Using as a foil recent work in this area by John Rawls, I argue in (...) chapter one for a justificatory basis of human rights that advances values---in particular values of minimal democracy including the right to political participation---that may have emerged historically alongside liberalism but that we ought not consider specifically liberal. My account diverges form Rawls' at this point: he does not believe that such values can be defended from premises that are not specifically liberal. ;Since a group is, after all, merely a collection of individuals, liberalism appears to be committed, unsatisfactorily, to a permissive right to secede in the sense that, other things being equal, groups always ought to be permitted to secede voluntarily. I show in my second chapter that liberalism is not committed to this permissive view. Though liberalism implies that no one has a duty to refrain from secession, it does not support the stronger thesis that states must permit groups to secede if they wish. My treatment of secession argues for a more general framework in which those liberties whose protection is of basic importance to liberalism are distinguished from those whose protection is not so guaranteed. ;Derek Parfit has put forth a general difficulty regarding our obligations to future generations to which I respond in chapter three. Parfit claims, plausibly, that we may suppose a major public policy decision to have sufficiently broad ramifications that in about two hundred years there would be nobody alive who would have been alive had some different policy been selected. But then the choice of such a policy would not make those people worse off, since they would not otherwise have been born. This would remain so even in the case of policies that cause the lives of future generations to be of a very low quality. Parfit's "Non-Identity Problem" challenges us to provide plausible moral reasons against such public policies. ;I argue that the only adequate response to this problem comes from a liberal focus on the rights of future generations, and the moral status that this confers on them. Taking such seriously, many public polices can be shown to be objectionable despite the fact that such policies may not harm the interests of those affected by them. (shrink)

Expectations of receiving personal health information as a fringe benefit of biospecimen donation—termed diagnostic misconception—are increasingly documented. We developed an instrument measuring conflation of observational biospecimen-based research and clinical care for use with Latino communities, who may be particularly affected by diagnostic misconception due to limited health care access.

Many publicly-funded health systems apply cost-benefit frameworks in response to the moral dilemma of how best to allocate scarce healthcare resources. However, implementation of recommendations based on costs and benefit calculations and subsequent challenges have led to ‘special cases’ with certain types of health benefits considered more valuable than others. Recent debate and research has focused on the relative value of life extensions for people with terminal illnesses. This research investigates societal perspectives in relation to this issue, in the UK.

Defense of reproductive choice is an important motivation in women's self-protection psychology for which the “staying alive theory” cannot fully account. Evidence indicates that some elements of women's self-protection psychology function to protect reproductive choice rather than survival, or may be equally well explained by either motivation. Integrating perspectives will result in greater explanatory breadth and precision in theory testing.

Professional workplaces that embody an “ideal worker” image that is implicitly white and male set-up persistent biases against the competence and suitability for authority of those who are not white men, forcing them to work harder to prove their competence and fit in. The added labor of coping with these burdens is largely invisible to dominant actors in the workplace who do not experience them. To facilitate change by making such burdens visible for all, we present data from a survey (...) of 1,349 architects, including white, Asian, Black, Latinx, and mixed race/other underrepresented men and women, about their specific behavioral experiences of prove-it-again bias, tightrope bias, problems of fit, exclusion, emotion work, and interruptions. Across all measures, white men architects report significantly lower levels of these burdens than do women of any race and almost all non-white men. Consistent with status expectations and stereotype prototypicality theories, we find intersectional patterns in the relative burdens experienced by women and men of different racial groups. Gender differences in bias experiences are greatest among white, less among Asian, and least among Black architects. Women of color report the highest levels of bias overall. (shrink)

What accounts for the prestige of quantitative methods? The usual answer is that quantification is desirable in social investigation as a result of its successes in science. Trust in Numbers questions whether such success in the study of stars, molecules, or cells should be an attractive model for research on human societies, and examines why the natural sciences are highly quantitative in the first place. Theodore Porter argues that a better understanding of the attractions of quantification in business, government, (...) and social research brings a fresh perspective to its role in psychology, physics, and medicine. Quantitative rigor is not inherent in science but arises from political and social pressures, and objectivity derives its impetus from cultural contexts. In a new preface, the author sheds light on the current infatuation with quantitative methods, particularly at the intersection of science and bureaucracy. (shrink)

Ideas for integrating AI into politics are now emerging and advancing at accelerating pace. This chapter highlights a few different varieties and show how they reflect different assumptions about the value of democracy. We cannot make informed decisions about which, if any, proposals to pursue without further reflection on what makes democracy valuable and how current conditions fail to fully realize it. Recent advances in political philosophy provide some guidance but leave important questions open. If AI advances to a state (...) where it can secure superior political outcomes, leading perspectives in political philosophy suggest that democracy may become obsolete. If we find this suggestion troubling, we need to put the case for democracy on stronger foundations. (shrink)

Not until the twentieth century did science come to be regarded as fundamentally technical in nature. A technical field, after all, meant not just a difficult one, but one relying on concepts and vocabulary that matter only to specialists. The alternative, to identify science with an ideal of public reason, attained its peak of influence in the late nineteenth century. While the scale and applicability of science advanced enormously after 1900, scientists have more and more preferred the detached objectivity of (...) service to bureaucratic experts over the cultivation of an engaged public. This reshaping of science, which has been both celebrated and condemned, provided a stimulus to the incipient field of history of science, and it remains a key historical problem. (shrink)

Optimal foraging theory has been criticized for underestimating patch exploitation time. However, proper modeling of costs not only answers these criticisms, but it also explains apparently irrational behaviors like the sunk-cost effect. When a forager is sure to experience high initial costs repeatedly, the forager should devote more time to exploitation than searching in order to minimize the accumulation of said costs. Thus, increased recognition or reconnaissance costs lead to increased exploitation times in order to reduce the frequency of future (...) costs, and this result can be used to explain paradoxical human preference for higher costs. In fact, this result also provides an explanation for how continuing a very costly task indefinitely provides the optimal long-term rate of gain; the entry cost of each new task is so great that the forager avoids ever returning to search. In general, apparently irrational decisions may be optimal when considering the lifetime of a forager within a larger system. (shrink)

In this study, we examine investor and firm response to the California Transparency in Supply Chains Act of 2010. The CTSCA requires large retail and manufacturing firms to disclose efforts to eradicate slavery and human trafficking from their supply chains and is a rare example of mandated corporate social responsibility disclosure. Based on a sample of 105 retail companies subject to the CTSCA, we find a significant negative market reaction to the passing of the CTSCA. Furthermore, we find that the (...) reaction is significantly more negative for larger firms and companies facing greater supply chain risks, suggesting that investors place a negative value on exposure to legitimacy threats in the social domain. With respect to company disclosure response, we document relatively high compliance with the legislation, although we also find that the disclosure response appeared to be more symbolic than substantive in nature. Finally, our analysis indicates that both disclosure choice and disclosure extensiveness were significantly higher for the high-supply chain risk companies, suggesting that the response was influenced by concerns with strategic legitimation. Overall, the limited quality of disclosure suggests that, without additional rules and guidance, mandates alone may not lead to meaningful social disclosure. (shrink)
