Word in noise identification is facilitated by acoustic differences between target and competing sounds and temporal separation between the onset of the masker and that of the target. Younger and older adults are able to take advantage of onset delay when the masker is dissimilar to the target word, but only younger adults are able to do so when the masker is similar. We examined the neural underpinning of this age difference using cortical evoked responses to words masked by either (...) Babble or Noise when the masker preceded the target word by 100 or 600 ms in younger and older adults, after adjusting the signal-to-noise ratios to equate behavioural performance across age groups and conditions. For the 100 ms onset delay, the word in noise elicited an acoustic change complex response that was comparable in younger and older adults. For the 600 ms onset delay, the ACC was modulated by both masker type and age. In older adults, the ACC to a word in babble was not affected by the increase in onset delay whereas younger adults showed a benefit from longer delays. Hence, the age difference in sensitivity to temporal delay is indexed by early activity in the auditory cortex. These results are consistent with the hypothesis that an increase in onset delay improves stream segregation in younger adults in both noise and babble, but only in noise for older adults and that this change in stream segregation is evident in early cortical processes.

ABSTRACT:After a transgression has occurred within an organization, a primary concern is the reintegration of the affected parties back into the organizational community. However, beyond offenders and victims, reintegration depends on the views of organizational peers and their desire to interact with these parties. In two studies, we demonstrated that offender amends and victim forgiveness interact to predict peer reintegrative outcomes. We found evidence of backlash against unforgiving victims: Peers wanted to work the least with victims who rejected appropriate amends, (...) thus penalizing them for their failure to contribute to the restoration process. This backlash effect was due to decreased liking of the victim and the perceived failure to repair the offender-victim relationship. These findings demonstrate that peers expect both offenders and victims to do their part to achieve reconciliation following transgression, and both may suffer the consequences of failing to meet peer expectations. Implications for reintegration within organizations are discussed. (shrink)

Who is this young woman that seems to have chosen to die by default? She is in effect parentless at a labile and vulnerable age. An attempt at a different social environment has failed. She is depressed. Unknowns are her issues, feelings, and concerns and whether antidepressants have been tried, and if so, what their effect has been. Additional data not given is whether dialysis has been tried, and if not, why not? The known track record of adolescents doing poorly (...) on dialysis would be a concern, but then so is the loss of a scarce resource. (shrink)

Incivility in online commenting sections can create a hostile environment and result in the silencing of vulnerable voices. Accordingly, content websites and social media platforms have an ethical responsibility—one that aligns with their strategic interests—to minimize users' exposure to uncivil content. To this end, platforms invest great effort and budget in automatic and manual filtering mechanisms. Yet, these efforts create a competing ethical quandary, as they often come at the expense of free expression, particularly in cases where comments do not (...) explicitly infringe on stated guidelines but might nevertheless be interpreted as offensive. In this paper, we examine an alternative moderation approach, based on comment reordering as opposed to deletion of uncivil comments. Specifically, we show that exposure to uncivil (vs. civil) comments located in the head or at the bottom of a list of comments increases subsequent commenters' likelihood of posting uncivil comments themselves. Exposure to uncivil comments in the middle of a list, however, does not significantly enhance commenters' likelihood of commenting uncivilly. These results offer new theoretical insight into how incivility is transferred between users in online environments. Our results also suggest a straightforward technological solution for mitigating online incivility, which is more ethical and practical than current industry standards. This involves placing civil comments at the beginning and end of the comment thread, with uncivil comments located in the middle. (shrink)

Responsible conduct of research courses are widely taught, but little is known about the purposes or effectiveness of such courses. As one way to assess the purposes of these courses, students were surveyed about their perspectives after recent completion of one of eleven different research ethics courses at ten different institutions. Participants enrolled in RCR courses in spring and fall of 2003 received a voluntary, anonymous survey from their instructors at the completion of the course. Responses were received from 268 (...) participants. Seventy-seven percent of open-ended responses listed specific kinds of information learned; only a few respondents talked about changes in skills or attitudes. The perception that courses did more to provide information than to foster skills or attitudes was verified in quantitative responses. Over 75% of the respondents specifically noted that courses were useful in preparing them to recognize, avoid, and respond to research misconduct. The two principal findings of this multi-institutional study are that respondents reported: a wide variety of positive outcomes for research ethics courses, but that the impact on knowledge was greater than that for changes in skills or attitudes.

Nelson Goodman’s disparate writings are often discussed and written about only within their own particular discipline, such that the epistemology is discussed in contrast to others’ epistemology, the aesthetics is contrasted with more traditional aesthetics, and the ontology and logic is viewed in opposition to both other contemporary philosophers and to his historical predecessors. This book argues that that is not an adequate way to view Goodman. The book is divided into three sections: The Metaphysics, The Epistemology, The Aesthetics. I (...) demonstrate, firstly, the dependency of his epistemology and aesthetics on his early metaphysical and ontological writings, and secondly, that it is the very application of those metaphysical and ontological positions to the rest of his philosophical writings that is the source of much of which fails to be completely satisfactory in his aesthetics. They are sequential sections within each providing the ground rules for the next section and, furthermore, providing the reasons for limitations on the terms available to the subsequent section(s). Thus the Metaphysics is an explication of Gooodman’s basic nominalist ontology and logic, and it is upon those principles that he builds his epistemology. It is the sum of both the metaphysics and the epistemology, with the nominalist principle as the guiding force, which constructs the aesthetics. At the end of each section, the consequent limitations imposed on his terms and concepts available to him are explicated, such that, by the end of the book, I am able to delineate the constraints imposed upon the aesthetics by both the metaphysics and the epistemology.

Despite more than 25 years of a requirement for training in the responsible conduct of research, there is still little consensus about what such training should include, how it should be delivered, nor what constitutes “effectiveness” of such training. This lack of consensus on content, approaches and outcomes is evident in recent data showing high variability in the development and implementation of RCR instruction across universities and programs. If we accept that one of the primary aims of instruction in RCR/research (...) ethics is “to foster a community of social responsibility”, then it makes sense to consider the research environment itself—where learning one’s science happens where one also engages in social interaction around that science. In order to take the best advantage of that already existing/naturally occurring research environment, the authors, through a deliberative, collaborative, and integrative process, crafted a workshop curriculum meant to arm research faculty with concrete and specific tools to effectively introduce research ethics in the context of the research environment.

Willingness to collaborate across disciplinary boundaries is necessary but not sufficient for project success. This is a case study of a transdisciplinary project whose success was constrained by contextual factors that ultimately favoured technical and scientific forms of knowledge over the cultural intelligence that might ensure technical solutions were socially feasible. In response to Alaskan Water and Sewer Challenge, an international team with expertise in engineering, consultative design and public health formed in 2013 to collaborate on a two-year project to (...) design remote area water and sanitation systems in consultation with two native Alaskan communities. Team members were later interviewed about their experiences. Project processes are discussed using a ‘Knowledge Ecology’ framework, which applies principles of ecosystems analysis to knowledge ecologies, identifying the knowledge equivalents of ‘biotic’ and ‘abiotic’ factors and looking at their various interactions. In a positivist ‘knowledge integration’ perspective, different knowledges are like Lego blocks that combine with other ‘data sets’ to create a unified structure. The knowledge ecology framework highlights how interactions between different knowledges and knowledge practitioners are shaped by contextual factors: the conditions of knowledge production, the research policy and funding climate, the distribution of research resources, and differential access to enabling infrastructures. This case study highlights the importance of efforts to negotiate between different knowledge frameworks, including by strategic use of language and precepts that help translate social research into technical design outcomes that are grounded in social reality.

Although deeply committed to the model of nondirective counseling, most genetic counselors enter the profession with certain assumptions about health and disability—for example, that it is preferable to be a hearing person than a deaf person. Thus, most genetic counselors are deeply troubled when parents with certain disabilities ask for assistance in having a child who shares their disability. This ethical challenge benefits little from viewing it as a conflict between beneficence and autonomy. The challenge is better recast as a (...) conflict between parental autonomy and the child's future autonomy. (shrink)

Henry Molaison, aged eighty-two, died at the end of 2008, and just after noon on exactly the first anniversary of his death, December 2, 2009, scientists began slicing his brain into 2,500 tissue samples. Known primarily in his lifetime as only H.M., he left his brain to science so that it could be dissected and digitally mapped – a gift much beloved by many scientists. An amnesiac in life, H.M. first rose to prominence in 1962 when Dr. Brenda Milner, a (...) pioneer in the field of neuropsychology, demonstrated that though H.M. was severely amnesic and could not remember past activities, he could nevertheless learn certain habits. The experiment involved the now famous mirror drawing. This article, written by a philosopher/artist and a neuroscientist/neuroaesthetician, argues that artists are unable to verbally articulate thoughts about their own art practice for reasons similar to why H.M. could not. All memories are not stored in the same part of the brain. Different categories of memories i.e., semantic memory or procedural memory, are stored in different parts of the brain. We argue that the procedural memory is not readily accessible to semantic memory. (shrink)

What makes an artwork bring on the demands of censorship? Is it when it offends a majority of people, a significant minority, or just a few? And is it censorship when the work is denied all venues of exhibition or is it also censorship when it is denied public grants and/or exhibitions dependent on public funds i.e. in museums, but granted the right of private exhibition i.e. in commercial galleries?The article "Censorship, 'Decency' and Dollars" by Dena Shottenkirk deals with (...) the thorny and difficult issues surrounding art censorship, and the political and aesthetic consequences of them. J.S. Mill's harm/offense distinction is sometimes used in such discussions regarding paternalism, but, even setting aside Mill's back-pedaling on public decency concerns, the harm/offense distinction is not the clear-cut one we'd often want in dealing with contemporary culture. How much of modernism's avant-garde would exist without tweaking the boundaries of harm and offense, and how dependent are our free speech rights on such cultural expressions? While hoping to defend the rights of perverse expression and - at the same time-democracy everywhere, the line drawn on what-gets-shown and who-gets-to-decide are tempestuous issues indeed. (shrink)

There is a flood of papers being published on new ways to diagnose Alzheimer disease before it is symptomatic, involving a combination of invasive tests , and pen and paper tests. This changes the landscape with respect to genetic tests for risk of AD, making rational suicide a much more feasible option. Before the availability of these presymptomatic tests, even someone with a high risk of developing AD could not know if and when the disease was approaching. One could lose (...) years of good life by committing suicide too soon, or risk waiting until it was too late and dementia had already sapped one of the ability to form and carry out a plan. One can now put together what one knows about one's risk, with continuing surveillance via these clinical tests, and have a good strategy for planning one's suicide before one becomes demented. This has implications for how these genetic and clinical tests are marketed and deployed, and the language one uses to speak about them. The phrase ‘there is nothing one can do’ is insulting and disrespectful of the planned suicide option, as is the language of the Risk Evaluation and Education for Alzheimer's Disease studies and others that conclude that it is ‘safe’ to tell subjects their risk status for AD. Further, the argument put forward by some researchers that presymptomatic testing should remain within research protocols, and the results not shared with subjects until such time as treatments become available, disrespects the autonomy of people at high risk who consider suicide an option.

There is strong sentiment for a policy which would exclude foreigners from access to organs from American cadaver donors. One common argument is that foreigners are free riders; since they are not members of the community whichgives organs, it would be unfair to allow them toreceive such a scarce resource.This essay examines the philosophical basis for the free rider argument, and compares that with the empirical data about organ donation in the U.S. The free rider argument ought not to be (...) used to exclude foreign nationals because it is based on fallacious assumptions about group membership, and how the giving community is defined. Polls show that even among the seventy-five per cent of Americans who support organ donation, only seventeen per cent had taken the small step of filling out donor cards. Therefore, it goes against logic to define the giving community as coextensive with American residency, while excluding foreigners who might well have become donors had they lived in countries which provided that option.

The question regarding how to characterize aesthetics has been revived with the publication of Bence Nanay’s _Aesthetics as Philosophy of Perception_. This paper takes seriously Dustin Stokes’ criticisms of Nanay’s book regarding Nanay’s inability to distinguish between ordinary expert visual tasks (e.g., sorting for sock color or ornithology) and aesthetic experience. Using empirical research on gist perception and its reliance on low-level features in visual experience, I develop a theory that distinguishes expert visual tasks and aesthetic experiences by differentiating two (...) different kinds of distributed attention over properties. I argue that expert visual tasks are instances of property attribution in a mode of conscious attention, while aesthetics is a kind of distributed attention that significantly relies on the reiteration of gist-like lowlevel features. Gist, often referred to in visual science as “preattentive” mode, gives us a model to understand the perceptual processes that are specific to aesthetics. This comports with our common-sense definition of aesthetics as both distinguishable from ordinary expert visual tasks and an experience that makes prominent sensory aspects of visual experience.

This is a book about the culture wars, particularly those in the U.S. To gain a more complete view of what they are and what is at stake, I examine the relationships between funding, censorship, and democracy by looking closely at particular examples where the government at least wanted to refuse funding (it sometimes in fact succeeded) and to then look at the issues that arise. The main examples I have chosen is Andres Serrano, whose Piss Christ helped many people’s (...) blood pressure rise, and who, along with Robert Mapplethorpe, caused the late 1980s and early 1990s outcry over the National Endowment for the Arts. These are the instances that started the so-called culture wars more than two decades ago and it is in this form that they still exist today. This book is an attempt to rationally and completely examine the issues at hand and to finally set to rest the contentions that underlie the debates, not just in their current specific form in the United States, but in general. These are the philosophical issues, which include not only the obvious political concerns around demands for liberty, free speech, and the compromises inherent in social organizations, but the epistemological issues at the heart of art. What is it that we learn from art and why is the presence of culture so often beloved and a deprivation of it bereaved? (shrink)

This volume addresses key questions related to how content in thought is derived from perceptual experience. It includes chapters that focus on single issues on perception and cognition, as well as others that relate these issues to an important social construct that involves both perceptual experience and cognitive activities: aesthetics. While the volume includes many diverse views, several prominent themes unite the individual essays: a challenge to the notion of the discreet, and non-temporal, unit of perception, a challenge to the (...) traditional divide between perception and cognition, and a challenge to the traditional divide between unconscious and conscious intentionality. Additionally, the chapters discuss the content of perceptual experience, the value of traditional notions of content, disjunctivism, adverbialism, and phenomenal experience. The final section of essays dealing with perception and cognition in aesthetics features work in experimental aesthetics and unique perspectives from artists and gallerists working outside of philosophy. Perception, Cognition and Aesthetics is a timely volume that offers a range of unique perspectives on debates in philosophy of mind surrounding perception and cognition. It will also appeal to scholars working in aesthetics and art theory who are interested in the ways these debates influence our understanding of art. ists and gallerists working outside of philosophy.

While it may be useful to consider the development of new topics in teaching the responsible conduct of research (RCR), it is perhaps equally important to reconsider the traditionally taught core topic areas in both more nuanced and broader ways. This paper takes the topic of authorship as an example. Through the description of two specific cases from sociocultural anthropology, ideas about credit and responsibility are examined. It is suggested that placing more focus on the array of meanings found in (...) the act of authoring might help students see themselves as part of a wider community both of scientists and beyond science.

This study integrates institutional theory and social cognitive theory to describe how peripheral organizations can accidentally bring about radical change even in highly institutionalized and change-resistant fields. The empirical context is the field of banking in Ireland (1995–2001), where a peripheral bank triggered a shift away from traditionally conservative and risk-averse banking values toward aggressive values of entrepreneurial risk taking. The introduction of a new approach to banking was attributed to three factors: (1) a benevolent environment, which made this innovation (...) feasible and timely, (2) the state of the field, which had gaps that could be addressed through specialization, and (3) prior successes, which created hubris in the senior managers, thereby increasing the pace and scope of adoption of this approach. Eventually, what started as a specialized and entrepreneurial approach led to the spread of a risky approach to banking across the entire field. The study highlights the risks of hubris, in that media praise and early successes can increase the pace of adoption of innovations which offer short-term gains but are detrimental in the long term.

Scientific developments take place in a socio-political context but scientists often ignore the ways their innovations will be both interpreted by the media and used by policy makers. In the rush to neuroscientific discovery important questions are overlooked, such as the ways: (1) the brain, environment and behavior are related; (2) biological changes are mediated by social organization; (3) institutional bias in the application of technical procedures ignores race, class and gender dimensions of society; (4) knowledge is used to the (...) advantage of the powerful; and (5) its applications may reinforce existing structures of power that pose ethical questions about distributive justice. The case of crime, deception and functional Magnetic Resonance Imaging (fMRI) shows the complexity, and the political and ethical challenges that confront those who seek to use neuroscience to explain the etiology of crime, and who base policy on its findings. An ethically grounded neuroscience needs to take account of existing structures of power and difference, and to develop a public neuropolitical consciousness that ensures that those subject to risk by the application of science and technology are participants in the decision-making processes involving the implementation of policies that affect them.

This analysis provides a fact-based examination of the doctrine of nationalism and its idol, the national interest, couched within the context of twentieth century wartime presidential speeches and writings. What is significant about this rhetoric is that it provides a clear delineation of the growth of nationalism as America’s underlying political ideology and has fueled reliance on the concept of the national interest in guiding foreign affairs. By building public policies around their own perceptions of what is in the public (...) good—perceptions at times motivated by genuine patriotism, but all too often motivated by private interests—America’s political leaders have routinely resorted to lies and subterfuge as the means to their nationalist ends. Presidents and their advisers have learned that by exerting their power over the people, by controlling the content and context of political discourse, they can manipulate public opinion, winning support for policies and actions that appear to serve public interests, but in actuality are opposed to what people want or need.
