In the vertebrate spinal cord, motoneurons are clustered into longitudinal columns in agreement with the targets they innervate. Motoneurons within each column acquire properties early in development that ensure their axons navigate to appropriate targets, but how this target identity is specified is unknown. Recently, Tsuchida et al.(1) described the expression of putative regulatory genes within motor columns in the chicken spinal cord. Combinations of LIM‐family homeobox genes differentially mark columns that project to distinct target groups. Expression precedes column formation (...) and axon outgrowth, making these genes candidates for specifying the target identity of motoneuron groups. (shrink)

Post-Traumatic Stress Disorder is a major public health concern in both civilian and military populations, across race, age, gender, and socio-economic status. While PTSD has been around for centuries by some name or another, its definition and description also continue to evolve. Within the last few years, the American Psychological Association has published the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders, which includes some major changes in the diagnostic criteria for PTSD. Recent data on epidemiology, etiological (...) theories, and empirically supported methods of treatment, as well as implications for legal processes and criminal justice system personnel, are discussed.

New coverage of the recent wars in Afghanistan and Iraq, and the ensuing public education campaigns by the Department of Veterans Affairs and private veterans advocacy groups combine to call the public's attention to the many potential mental health problems associated with traumatic event exposure. Indeed, since 2001, Operation Iraqi Freedom and Operation Enduring Freedom combat and peacekeeping missions have been characterized by high levels of exposure to acts of extreme violence, with often gruesome effects. Less publically discussed is the (...) fact that a surprisingly large number of United States civilians also report exposure to traumatic events, such as severe interpersonal violence, natural disasters, and serious automobile accidents. In fact, approximately 70% of randomly sampled respondents indicated that they have experienced an incident characterized by significant perceived life threat at some point during their lives.

One important problem in cognitive science is to understand the development of cognitive processes in children and to devise computer models to explore the mechanisms that underlie these changes. Our research addresses these general goals. In particular, we are concerned with developmental changes in cognitive strategies in typical children and in children with mild mental retardation.

We report on the deliberations of an interdisciplinary group of experts in science, law, and philosophy who convened to discuss novel ethical and policy challenges in stem cell research. In this report we discuss the ethical and policy implications of safety concerns in the transition from basic laboratory research to clinical applications of cell-based therapies derived from stem cells. Although many features of this transition from lab to clinic are common to other therapies, three aspects of stem cell biology pose (...) unique challenges. First, tension regarding the use of human embryos may complicate the scientific development of safe and effective cell lines. Second, because human stem cells were not developed in the laboratory until 1998, few safety questions relating to human applications have been addressed in animal research. Third, preclinical and clinical testing of biologic agents, particularly those as inherently complex as mammalian cells, present formidable challenges, such as the need to develop suitable standardized assays and the difficulty of selecting appropriate patient populations for early phase trials. We recommend that scientists, policy makers, and the public discuss these issues responsibly, and further, that a national advisory committee to oversee human trials of cell therapies be established. **NB we did not reccommend a NAC, we think it might be appropriate**.

Preparing the Next Generation of Oral Historians is an invaluable resource to educators seeking to bring history alive for students at all levels. Filled with insightful reflections on teaching oral history, it offers practical suggestions for educators seeking to create curricula, engage students, gather community support, and meet educational standards. By the close of the book, readers will be able to successfully incorporate oral history projects in their own classrooms.

If stem cell-based therapies are developed, we will likely confront a difficult problem of justice: for biological reasons alone, the new therapies might benefit only a limited range of patients. In fact, they might benefit primarily white Americans, thereby exacerbating long-standing differences in health and health care.

The Monographs produced by the International Agency for Research on Cancer (IARC) apply rigorous procedures for the scientific review and evaluation of carcinogenic hazards by independent experts. The Preamble to the IARC Monographs, which outlines these procedures, was updated in 2019, following recommendations of a 2018 expert Advisory Group. This article presents the key features of the updated Preamble, a major milestone that will enable IARC to take advantage of recent scientific and procedural advances made during the 12 years since (...) the last Preamble amendments. The updated Preamble formalizes important developments already being pioneered in the Monographs Programme. These developments were taken forward in a clarified and strengthened process for identifying, reviewing, evaluating and integrating evidence to identify causes of human cancer. The advancements adopted include strengthening of systematic review methodologies; greater emphasis on mechanistic evidence, based on key characteristics of carcinogens; greater consideration of quality and informativeness in the critical evaluation of epidemiological studies, including their exposure assessment methods; improved harmonization of evaluation criteria for the different evidence streams; and a single-step process of integrating evidence on cancer in humans, cancer in experimental animals and mechanisms for reaching overall evaluations. In all, the updated Preamble underpins a stronger and more transparent method for the identification of carcinogenic hazards, the essential first step in cancer prevention. (shrink)

This paper explores how the "environmental turn" for the last 25 years has been shaping remembrance of the destruction of Europe's Jewish populations. I argue that climate change is not just one more catastrophe to pass into the broad analogical field of the Holocaust. In fact, international Holocaust consciousness and understandings of what we now call the Anthropocene have long been intertwined and mutually constitutive. The paper starts in the 1990s with acclaimed writers Anne Michaels and W.G. Sebald, who sought (...) to recast the Holocaust's significance to modernity against a long backdrop of geologic time. Their memorial fiction, which grounds the history of the Holocaust in the eroding landscapes of Europe, reflects a growing and urgent global concern for the vulnerability of the environment and a sense of man's responsibility for preserving human and biological life. The paper then moves through more contemporary examples of the sublimation of Holocaust memory in discourse about global warming—evident in terms like "climate change denial" and calls to "bear witness" to mass extinction events. For better or worse, journalists and scholars who write about environmental activism frequently call on memory of World War II and genocide in order to redefine what constitutes "grievable life." Example authors include historian Timothy Snyder, who has predicted that climate change may lead to new genocidal wars over Lebensraum ; scientist James Lovelock, who has urged nation states to consider how to limit the coming influx of climate refugees; theorist Bruno Latour, who has argued, via Nazi philosopher Carl Schmitt, that we must "name our enemies" in the new climate wars; and essayist Ari Brostoff who has attempted to think climate catastrophe through Walter Benjamin's meditations on the angel of history. The implicit question in all of their work is this: What histories and philosophical traditions can help us redefine humanity's entangled relationship to nature in order to take political responsibility for saving life on Earth? In other words, the Anthropocene requires "a usable past"—but what will that usable past be? (shrink)

In this chapter I problematize Beauvoir's analogical analyses in The Second Sex, arguing that her utilization of the race/gender analogy omits the experiences and oppressions of Black women. Furthermore, taking into account select secondary literature that emphasizes these issues, I argue that several of Beauvoir's white feminist defenders and critics share in common their non‐engagement with Black feminist literature on Beauvoir. Put another way, Black feminists who explicitly take up Beauvoir in their writings have remained largely unacknowledged in the secondary (...) literature on Beauvoir by white feminists. As a corrective to this erasure, I highlight the scholarly contributions of Black feminists including Loraine Hansberry, Chikwenye Ogunyemi, Deborah King, Oyeronke Oyewumi, and bell hooks. (shrink)

Background: Freezing of gait is a common symptom in Parkinson’s disease and can be difficult to treat with dopaminergic medications or with deep brain stimulation. Novel stimulation paradigms have been proposed to address suboptimal responses to conventional DBS programming methods. Burst-cycling deep brain stimulation delivers current in various frequencies of bursts, while maintaining an intra-burst frequency identical to conventional DBS.Objective: To evaluate the safety and tolerability of BCDBS in PD patients with FOG.Methods: Ten PD subjects with STN or GPi DBS (...) and complaints of FOG were recruited for this single center, single blinded within-subject crossover study. For each subject, we compared 4, 10, and 15 Hz BCDBS to conventional DBS during the PD medication-OFF state.Results: There were no serious adverse events with BCDBS. It was feasible and straightforward to program BCDBS in the clinic setting. The benefit was comparable to conventional DBS in measures of FOG, functional mobility and in PD motor symptoms. BCDBS had lower battery consumption when compared to conventional DBS.Conclusions: BCDBS was feasible, safe and well tolerated and it has potential to be a viable future DBS programming strategy.

In this article the author responds to the mini-symposium on his work provided by Kathryn Gines and Shannon Sullivan, both of whom focus on the issue of intersectionality. Gines's article looks at the treatment of race and gender in one of the chapters in Mills's book with Carole Pateman, Contract and Domination. Her major criticism centers on what she sees as Mills's failure to recognize nonwhite men's patriarchal domination of nonwhite women. However, the present article claims that this criticism (...) is simply a misreading of what Mills says in the chapter. Sullivan's article reviews the various stages in Mills's career path, with special attention to race and class. Her major criticism is that while nominally conceding intersectionality, Mills still holds on to the assumption that different variables can be discretely singled out. In reply, this article argues that a recognition of intersectionality need not commit one to rejecting claims about the possible differential causal and explanatory significance of the intersecting variables.

Reform of the federal income tax system has become a perennial item on the domestic policy agenda of the United States, although there is considerable uncertainty over specifics. Indeed the recent report of the President's Advisory Panel on Federal Tax Reform recommended not one but two divergent policy directions. In Fundamental Tax Reform, top experts in tax policy discuss a wide range of issues raised by the prospect of significant tax reform, identifying the most critical questions and considering whether the (...) answers are known, unknown--or unknowable. The debates over tax reform usually concern the advantages and disadvantages of income-based taxation as opposed to any of the several alternative forms of consumption-based taxation. The book opens with chapters that discuss the strengths, weaknesses, and political feasibility of these options. Other chapters consider the effect of tax reform on businesses, especially their investment behavior, and include a discussion of possible problems in any transition to a consumption-based tax; international taxation issues arising in an era of globalization; and individual behavioral response to tax reform, including a view of the topic from the perspective of the relatively new field of behavioral economics.

How Doctors Think defines the nature and importance of clinical judgment. Although physicians make use of science, this book argues that medicine is not itself a science but rather an interpretive practice that relies on clinical reasoning. A physician looks at the patient's history along with the presenting physical signs and symptoms and juxtaposes these with clinical experience and empirical studies to construct a tentative account of the illness. How Doctors Think is divided into four parts. Part one introduces the (...) concept of medicine as a practice rather than a science; part two discusses the idea of causation; part three delves into the process of forming clinical judgment; and part four considers clinical judgment within the uncertain nature of medicine itself. In How Doctors Think, Montgomery contends that assuming medicine is strictly a science can have adverse side effects, and suggests reducing these by recognizing the vital role of clinical judgment.

The Catholic Tradition requires the faithful to form and follow their conscience. This is the case even with the recognition that consciences can be malformed and one can make errors in practical judgments. Water Shaping Stone examines various aspects of this tradition regarding conscience by using, among other sources, twentieth-century magisterial documents, theologians' works, and Scripture. Kathryn Lilla Cox argues that while the Magisterium retains teaching authority, and a responsibility to help form consciences through its teaching, focusing only on (...) the Magisterium leads to incomplete formation. A more holistic vision of conscience formation means considering the formation of the moral agent to be a multifaceted process that draws on, for example, teaching, prayer, rituals, Scripture, practices, and virtues, along with relationships with the Triune God and communities of accountability. This vision of conscience formation retains the magisterial teaching authority while acknowledging discipleship as the theological basis for making and assessing practical judgments of conscience.

In Moral Passages, Kathryn Pyne Addelson presents an original moral theory suited for contemporary life and its moral problems. Her basic principle is that knowledge and morality are generated in collective action, and she develops it through a critical examination of theories in philosophy, sociology and women's studies, most of which hide the collective nature and as a result hide the lives and knowledge of many people. At issue are the questions of what morality is, and how moral theories (...) (whether traditional or feminist) are implemented. Addelson takes up a large number of historical cases and contemporary social problems, including teen pregnancy, contraception and abortion, and gay rights. These cases allow her to see how the knowledge and lives of some people are declared deviant or immoral, while those of others appear to show the public consensus. One case she uses throughout the book is Margaret Sanger's early work on birth control with the anarcho-syndicalist movement--a revisionist history that reveals rather than hides the collective nature of morality and knowledge. Addelson shows how the usual individualist philosophies promote theories which hide the authority of the professionals who make them. A collectivist approach, she argues, must show the part professionals play in collective action. Her aim is to allow professional knowledge makers to be morally and intellectually responsible. Based on Addelson's twenty years of work in feminist philosophy and interactionist sociology as well as her long-standing involvement in women's community organization, Moral Passages investigates how morality and knowledge are collectively enacted in today's world.

I am persuaded both by the theory of evil advanced by Claudia Card in The Atrocity Paradigm and by the idea that there are evils done to the environment; however, I argue that the theory of evil she describes has difficulty living up to her claim that it "can make sense of ecological evils the victims of which include trees and even ecosystems" (2002, 16). In this paper, I argue that Card's account of evil does not accommodate the kinds of (...) harms inflicted on ecosystems and such nonhuman individuals as trees. I consider the possibility that Card intends a much broader version of evils than the language of the atrocity paradigm lets on, with its attention to sentience and dignity. I'm so persuaded by the atrocity paradigm, however, that I retain the centrality of suffering and introduce the idea that atrocities are intuitively massive, that is, done to groups or generations and not an individual person, animal or tree, so that the paradigm encourages us to think of evil as it relates to far more holistic entities which include the sentient. Evil may require the sort of suffering that only sentience can give rise to, which is not to say we let out trees but says rather that it is impossible to identify wrongs to ecosystems and groups that are not also intertwined with the fates of their sentient dependents. I conclude that Card is right to emphasize victims' suffering as a chief component of evil, and that the ontology of what constitutes a victim must be interpreted broadly, not the notion of suffering.

Our experiences with many sorts of evils yield debates about the role of forgiveness as a possible moral response. These debates include (1) the preliminary question whether evils are, by definition, unforgivable, (2) the contention that evils may be forgivable but that forgiveness cannot entail reconciliation with one’s evildoer, (3) the concern that only direct victims of evils are in a position to decide if forgiveness is appropriate, (4) the conceptual worry that forgiveness of evil may not be genuine or (...) complete if hard feelings recur, (5) the interest of many in holding that forgiveness is never required, and (6) the concern that analyses of evil ought to prioritize the suffering, and credit the perspectives, of victims of evils, in tension with the possibility that forgiveness concerns the well-being of offenders. In this paper, I critically evaluate these concerns from the perspective of nonideal theory. I conclude that crediting victims’ perspectives is importantly basic to empirically informed moral theory, and that objections to forgiveness including (1) evil’s unforgivability ignore victims’ differing accounts. When we take actualities and experiences to be informative and central, some of the usual debates become less pressing, perhaps even moot. (shrink)

Pretty much everyone knows that our genes have at least something to do with how able or how high achieving we are. Some believe that we should not speak of this common knowledge, nor inquire into how genetic influence works or what it might mean. If we do not keep an open mind to the fact of genetic influence on academic achievement, however, then we cannot explore its possible implications. And if we do not consider the implications, then we cannot, (...) as a society, harness any potential benefits or avoid possible pitfalls. So that's what this essay is about—exploring what behavioral genetics research might be able to offer to educational theory, policy, and practice.We cannot yet use biological information to make accurate predictions for all children. We do know, however, that academic achievement is heritable, which is to say that differences between individuals are influenced by differences in their DNA. If genes are part of the problem for some pupils (to take the negative spin on this), then it seems likely that studying them could be part of a solution. And that's what behavioral geneticists are trying to do—to chart and understand pathways from DNA to behavior and to identify interventions that can maximize outcomes for all. The fact is, though, that we have an awfully long way to go. (shrink)

The author develops her account of Claudia Card's ethical work as nonideal ethical theory (NET). She clarifies Card's role in ethical theorizing of the recent past, partly in order to brief the unfamiliar reader on Card's ethics and nonideal theory, and partly to enter Card's contributions into the story of nonideal theory's emergence in philosophy. She then recommends, to other NET philosophers, the prioritization of (i) Card's rejection of the "administrative point of view", and (ii) Card's focus on "intolerable harms" (...) as critical to excellent ethical theorizing. She ends with the observation that NET may helpfully point toward reasons to take a pessimistic stance toward moral progress as elaborated in some classic texts in political philosophy; her appreciation of Card's insights yields a variety of pessimism that Card herself did not share.

Artificial intelligence (AI) has attracted an increasing amount of attention, both positive and negative. Its potential applications in healthcare are indeed manifold and revolutionary, and within the realm of medical imaging and radiology (which will be the focus of this paper), significant increases in accuracy and speed, as well as significant savings in cost, stand to be gained through the adoption of this technology. Because of its novelty, a norm of keeping humans “in the loop” wherever AI mechanisms are deployed (...) has become synonymous with good ethical practice in some circles. It has been argued that keeping humans “in the loop” is important for reasons of safety, accountability, and the maintenance of institutional trust. However, as the application of machine learning for the detection of lumbar spinal stenosis (LSS) in this paper’s case study reveals, there are some scenarios where an insistence on keeping humans in the loop (or in other words, the resistance to automation) seems unwarranted and could possibly lead us to miss out on very real and important opportunities in healthcare—particularly in low-resource settings. It is important to acknowledge these opportunity costs of resisting automation in such contexts, where better options may be unavailable. Using an AI model based on convolutional neural networks developed by a team of researchers at NUH/NUS medical school in Singapore for automated detection and classification of the lumbar spinal canal, lateral recess, and neural foraminal narrowing in an MRI scan of the spine to diagnose LSS, we will aim to demonstrate that where certain criteria hold (e.g., the AI is as accurate or better than human experts, risks are low in the event of an error, the gain in wellbeing is significant, and the task being automated is not essentially or importantly human), it is both morally permissible and even desirable to kick the humans out of the loop.

Sometimes form-meaning mappings in language are not arbitrary, but iconic: they depict what they represent. Incorporating iconic elements of language into a compositional semantics faces a number of challenges in formal frameworks as evidenced by the lengthy literature in linguistics and philosophy on quotation/direct speech, which iconically portrays the words of another in the form that they were used. This paper compares the well-studied type of iconicity found with verbs of quotation with another form of iconicity common in sign languages: (...) classifier predicates. I argue that these two types of verbal iconicity can, and should, incorporate their iconic elements in the same way using event modification via the notion of a context dependent demonstration. This unified formal account of quotation and classifier predicates predicts that a language might use the same strategy for conveying both, and I argue that this is the case with role shift in American Sign Language. Role shift is used to report others’ language and thoughts as well as their actions, and recently has been argued to provide evidence in favor of Kaplanian “monstrous” indexical expressions. By reimagining role shift as involving either quotation for language demonstrations or “body classifier” predicates for action demonstrations, the proposed account eliminates one major argument for these monsters coming from sign languages. Throughout this paper, sign languages provide a fruitful perspective for studying quotation and other forms of iconicity in natural language due to their lack of a commonly used writing system which is otherwise often mistaken as primary data instead of speech, the rich existing literature on iconicity within sign language linguistics, and the ability of role shift to overtly mark the scope of a language report. In this view, written language is merely a special case of a more general phenomenon of sign and speech demonstration, which accounts more accurately for natural language data by permitting more strict or loose verbatim interpretations of demonstrations through the context dependent pragmatics.

The authors examine the nature of the relationship between social science and philosophy and address the sort of work social science should do, and the role and sorts of claims that an accompanying philosophy should engage in. In particular, the authors reintroduce the question of ontology, an area long overlooked by philosophers of social science, and present a cricital engagement with the work of Roy Bhaskar. The book argues against the excesses of philosophising and commits itself to a philosophical approach (...) more deeply grounded in the social sciences. (shrink)

"Change is not merely necessary to life--it is life." That's Alvin Toffler, characteristically stating the profound in a profoundly direct way. And yes, even when we see change coming--as we're about to graduate from school, take a new job, get married--it's still not so easy to accept. And when we don't see it coming--oof, we have an even harder time. Here to help us embrace change and defuse its unsettling power is Change Happens, a full-color illustrated gift book to consult, (...) to share, to give, and to keep on a night table. Curated by Kathryn and Ross Petras, the ultimate connoisseurs of quotes whose books and calendars have over 4.5 million copies in print, these words of wisdom inspire us to be open to change and remind us that nothing positive in life ever happens without it. Arranged alphabetically by subject--including Adapting, Curveballs, Faith, Letting Go, Regrets, Second Chances, Vulnerability--it's a book to turn to in moments of need, when offering advice to a friend or loved one, when urging a child to find the courage to take a step, when marking an important occasion.
