A new set of models has resurrected a role for chromosomal inversions in the formation of new species.1-3 Traditional models, which are generally considered to be unlikely in most cases, had imagined that inversions might aid speciation by directly causing low hybrid fitness. In contrast, the newer models focus on the effect that inversions have on local recombination rates. A test of these models found a strikingly high rate of amino-acid substitution within regions where humans and chimpanzees differ by inversions, (...) suggesting perhaps that our ancestral species underwent a divergence process in which gene flow and inversions played a key role.4 However, it remains uncertain whether this interesting finding is actually consistent with the proposed model.

Base of the pyramid ventures seek to create “mutual value” for themselves and poor communities, but often use business models unadapted for the BoP context, and have been less successful than hoped. Sustainable business models’ multi-stakeholder lens offers a promising alternative path to mutual value, but BoP-based SBM studies are scarce. This single case study explores whether and how SBM characteristics manifest in the business model and value outcomes of Habi, a Manila footwear company successfully creating mutual value with BoP (...) suppliers. We find SBM characteristics underpin Habi’s dual-structure business model and success in four ways: viewing profits as a tool for community development resulted in designing both product and business model around community strengths; understanding communities as systems helped Habi address the complexities of poverty; balancing short-term business needs with a long-term, slow-growth approach led to their choice of investors; and implementing community value capture mechanisms ensured enduring community benefit.

Ludwig Wittgenstein's work has been widely interpreted and appropriated by subsequent philosophers, as well as by scholars from areas as diverse as anthropology, cultural studies, literary theory, sociology, law, and medicine. The Grammar of Politics demonstrates the variety of ways political philosophers understand Wittgenstein's importance to their discipline and apply Wittgensteinian methods to their own projects. In her introduction, Cressida J. Heyes notes that Wittgenstein himself was skeptical of political theory, and that his philosophy does not lead naturally or inexorably (...) toward any particular political position. Instead, she says, his ideas motivate certain attitudes toward the "game of politics" that the essays in this volume share: some contributors argue that political theory should use Wittgensteinian methods, others apply Wittgenstein's philosophy of language to figures and debates in areas of political theory (such as post-Kantian genealogy or Habermas's foundationalism), and still others reveal the ways Wittgenstein's concepts inform political foci as diverse as anthropomorphism, defining social group membership, and the nature of liberty.

Third wave anti-essentialist critique has too often been used to dismiss second wave feminist projects. I examine claims that Carol Gilligan's work is "essentialist," and argue that her recent research requires this criticism be rethought. Anti-essentialist feminist method should consist in attention to the relations of power that construct accounts of gendered identity in the course of different forms of empirical enquiry, not in rejecting any general claim about women or girls.

Background Retraction is a mechanism for alerting readers to unreliable material and other problems in the published scientific and scholarly record. Retracted publications generally remain visible and searchable, but the intention of retraction is to mark them as “removed” from the citable record of scholarship. However, in practice, some retracted articles continue to be treated by researchers and the public as valid content as they are often unaware of the retraction. Research over the past decade has identified a number of (...) factors contributing to the unintentional spread of retracted research. The goal of the Reducing the Inadvertent Spread of Retracted Science: Shaping a Research and Implementation Agenda (RISRS) project was to develop an actionable agenda for reducing the inadvertent spread of retracted science. This included identifying how retraction status could be more thoroughly disseminated, and determining what actions are feasible and relevant for particular stakeholders who play a role in the distribution of knowledge. -/- Methods These recommendations were developed as part of a year-long process that included a scoping review of empirical literature and successive rounds of stakeholder consultation, culminating in a three-part online workshop that brought together a diverse body of 65 stakeholders in October–November 2020 to engage in collaborative problem solving and dialogue. Stakeholders held roles such as publishers, editors, researchers, librarians, standards developers, funding program officers, and technologists and worked for institutions such as universities, governmental agencies, funding organizations, publishing houses, libraries, standards organizations, and technology providers. Workshop discussions were seeded by materials derived from stakeholder interviews (N = 47) and short original discussion pieces contributed by stakeholders. The online workshop resulted in a set of recommendations to address the complexities of retracted research throughout the scholarly communications ecosystem. -/- Results The RISRS recommendations are: (1) Develop a systematic cross-industry approach to ensure the public availability of consistent, standardized, interoperable, and timely information about retractions; (2) Recommend a taxonomy of retraction categories/classifications and corresponding retraction metadata that can be adopted by all stakeholders; (3) Develop best practices for coordinating the retraction process to enable timely, fair, unbiased outcomes; and (4) Educate stakeholders about pre- and post-publication stewardship, including retraction and correction of the scholarly record. -/- Conclusions Our stakeholder engagement study led to 4 recommendations to address inadvertent citation of retracted research, and formation of a working group to develop the Communication of Retractions, Removals, and Expressions of Concern (CORREC) Recommended Practice. Further work will be needed to determine how well retractions are currently documented, how retraction of code and datasets impacts related publications, and to identify if retraction metadata (fails to) propagate. Outcomes of all this work should lead to ensuring retracted papers are never cited without awareness of the retraction, and that, in public fora outside of science, retracted papers are not treated as valid scientific outputs.

If we must take mathematical statements to be true, must we also believe in the existence of abstract eternal invisible mathematical objects accessible only by the power of pure thought? Jody Azzouni says no, and he claims that the way to escape such commitments is to accept true statements which are about objects that don't exist in any sense at all. Azzouni illustrates what the metaphysical landscape looks like once we avoid a militant Realism which forces our commitment to (...) anything that our theories quantify. Escaping metaphysical straitjackets, while retaining the insight that some truths are about objects that do exist, Azzouni says that we can sort scientifically-given objects into two categories: ones which exist, and to which we forge instrumental access in order to learn their properties, and ones which do not, that is, which are made up in exactly the same sense that fictional objects are. He offers as a case study a small portion of Newtonian physics, and one result of his classification of its ontological commitments, is that it does not commit us to absolute space and time.

Firms are spending billions annually in the name of corporate social responsibility (CSR). Whilst markets are increasingly willing to reward good and responsible firms, they lack the instruments to measure corporate social performance (CSP). To convince investors and other stakeholders, firms invest heavily in building a reputation for good corporate behaviour. This article argues that reputations for CSP are often unrepresentative of true CSP and investigates how differences in 'perceived' and 'actual' – as measured by the Fortune and KLD databases, (...) respectively – can partly be explained by firm characteristics. Amongst other things, it finds that overrated firms are more likely to be relatively big, profitable, operating in non-polluting but competitive industries and with no history of wrong doings to their primary stakeholders. They will also typically spend a lot of effort satisfying the claims of their secondary stakeholders. Above all, the results emphasise the need for researchers to recognise that the databases measure different phenomenon and are not interchangeable. (shrink)

What makes fast, cumulative cultural evolution work? Where did it come from? Why is it the sole preserve of humans? We set out a self-assembly hypothesis: cultural evolution evolved culturally. We present an evolutionary account that shows this hypothesis to be coherent, plausible, and worthy of further investigation. It has the following steps: (0) in common with other animals, early hominins had significant capacity for social learning; (1) knowledge and skills learned by offspring from their parents began to spread because (...) bearers had more offspring, a process we call CS1 (or Cultural Selection 1); (2) CS1 shaped attentional learning biases; (3) these attentional biases were augmented by explicit learning biases (judgements about what should be copied from whom). Explicit learning biases enabled (4) the high-fidelity, exclusive copying required for fast cultural accumulation of knowledge and skills by a process we call CS2 (or Cultural Selection 2), and (5) the emergence of cognitive processes such as imitation, mindreading and metacognition – ‘cognitive gadgets’ specialised for cultural learning. This self-assembly hypothesis is consistent with archaeological evidence that the stone tools used by early hominins were not dependent on fast, cumulative cultural evolution, and suggests new priorities for research on ‘animal culture’.

This book offers an in-depth analysis of the cognitive and ethical role of emotion, particularly empathy, in medical practice. The author explains how doctors can use empathy in diagnosing and treating patients without jeopardizing their objectivity or projecting their own values on to patients.

What in our theoretical pronouncements commits us to objects? The Quinean standard for ontological commitment involves (nearly enough) commitments when we utter “there is” or “there are” statements without hope of eliminating these by paraphrase. Coupled with the indispensability of the truth of applied mathematical doctrine, the result is that the ontologically hard-nosed scientist is a Platonist—haplessly commited to abstracta. In this book Azzouni offers a way around the Quinean straitjacket: ontological commitment turns on how theories are (nearly enough) nailed (...) to the world. The specifics of how theories are applied indicates which among the posits of a theory are mere mathematical garb and which are genuine connections to items out there. In the first part of the book Azzouni undercuts the arguments, both actual and possible, in support of Quine’s criterion. An alternative criterion for what exists—ontological independence—is offered, one in sturdy accord with ordinary folk views on the matter. In the second part of the book, a beginning is made of bringing this alternative to bear upon scientific theories with a rich mathematical component. Along the way, old philosophical issues about absolute space and time versus relative space and time, the status of mathematical posits, such as spatial and temporal points, and so on, are illuminated.

Instead of stressing a partic- l uar regimented (...) notion of proof, the answer the mathematician will give ilikl.. (shrink)

Ordinary language and scientific language enable us to speak about, in a singular way, what we recognize not to exist: fictions, the contents of our hallucinations, abstract objects, and various idealized but nonexistent objects that our scientific theories are often couched in terms of. Indeed, references to such nonexistent items-especially in the case of the application of mathematics to the sciences-are indispensable. We cannot avoid talking about such things. Scientific and ordinary languages thus enable us to say things about Pegasus (...) or about hallucinated objects that are true, such as "Pegasus was believed by the ancient Greeks to be a flying horse," or "That elf I'm now hallucinating over there is wearing blue shoes." Standard contemporary metaphysical views and semantic analyses of singular idioms on offer in contemporary philosophy of language have not successfully accommodated these routine practices of saying true and false things about the nonexistent while simultaneously honoring the insight that such things do not exist in any way at all. That is, philosophers often feel driven to claim that such objects do exist, or they claim that all our talk isn't genuine truth-apt talk, but only pretence. This book reconfigures metaphysics in radical ways that allow the accommodation of our ordinary ways of speaking of what does not exist while retaining the absolutely crucial presupposition that such objects exist in no way at all, have no properties, and so are not the truth-makers for the truths and falsities that are about them.

Our experience of objects is very rich. We perceive objects as possessing individuation conditions. This, however, is a projection of our senses and thinking. Azzouni shows the resulting austere metaphysics tames many ancient philosophical problems about constitution, as well as contemporary puzzles about reductionism.

Most philosophers of mathematics try to show either that the sort of knowledge mathematicians have is similar to the sort of knowledge specialists in the empirical sciences have or that the kind of knowledge mathematicians have, although apparently about objects such as numbers, sets, and so on, isn't really about those sorts of things as well. Jody Azzouni argues that mathematical knowledge really is a special kind of knowledge with its own special means of gathering evidence. He analyses the (...) linguistic pitfalls and misperceptions philosophers in this field are often prone to, and explores the misapplications of epistemic principles from the empirical sciences to the exact sciences. What emerges is a picture of mathematics both sensitive to mathematical practice, and to the ontological and epistemological issues that concern philosophers. (shrink)

Gregory Bateson said that we are “governed by epistemologies that we know to be wrong” back in 1972. In the same book Bateson wrote: “the organism that destroys its environment destroys itself.” Almost forty years later, global ecological systems are in steep decline and converging crises make a deep evaluation of the underlying premises of our philosophical traditions an urgent imperative. This paper will suggest that the roots of the economic crisis are epistemological and that, to correct this error, whole (...) systems thinking and ecological literacy will become increasingly important in business management as well as in other disciplines. It will also suggest that the economic crisis opened new political space and has provided an opportunity for intervention. If we are brave enough to examine the roots of our problems there is possibility for renewal. (shrink)

When ordinary people - mathematicians among them - take something to follow from something else, they are exposing the backbone of our self-ascribed ability to reason. Jody Azzouni investigates the connection between that ordinary notion of consequence and the formal analogues invented by logicians. One claim of the book is that, despite our apparent intuitive grasp of consequence, we do not introspect rules by which we reason, nor do we grasp the scope and range of the domain, as it (...) were, of our reasoning. This point is illustrated with a close analysis of a paradigmatic case of ordinary reasoning: mathematical proof. (shrink)

Proactive policing strategies produce a range of harms to African Americans in poor urban communities. We know little, however, about how aggressive policing is experienced across gender by adolescents in these neighborhoods. The authors argue that important insights can be gained by examining the perspectives of African American youths and draw from in-depth interviews with youths in St. Louis, Missouri, to investigate how gender shapes interactions with the police. The comparative analysis reveals important gendered facets of African American adolescents' experiences (...) with and expectations of law enforcement. Young men described being treated routinely as suspects regardless of their involvement in delinquency and also reported police violence. Young women typically described being stopped for curfew violations but also expressed concerns about police sexual misconduct. This study highlights the differential harms of urban policing for African American young women and men and highlights the need for systematic attention to the intersections of race and gender in research on criminal justice practices.

This article examines the potential of Action Research informed by Dewey’s pragmatism as a research methodology in the social sciences. Not only a philosophical orientation, pragmatism is also a powerful mode of inquiry. When combined with the democratic research approach of Action Research, Deweyan pragmatism has great potential to shed light on educational and other social science questions, forward social change, and enact Dewey’s vision of radical social democracy. Although Dewey’s philosophy, one could argue, has never been mainstream in education (...) and in research, the combination of Deweyan philosophy and Action Research has the potential to revive interest in Dewey’s work and serve as an example of Deweyan ..

We have conducted a home-based study of children′s dream reports in which parents used open-ended interviewing styles to collect 88 dream reports from their 4- to 10-year-old children in the comfortable and supportive environment of their own homes. Particular attention was paid to formal properties including characters , settings, self-representation, and bizarreness. In contrast to previous studies, our data indicate that young children are able to give long, detailed reports of their dreams that share many formal characteristics with adult dream (...) reports. Because this wide range of dream mentation is only revealed to trusted confidants in a familiar and comfortable environment, an important implication is that the sleep laboratory may not be the best source of naturalistic dream data.

The present research isolates the fairness assessment of the process used by the retailer to set a price, as well as the distributive fairness of the price compared to the price that others are offered, and examines the combined effect of procedural fairness and distributive fairness on overall price fairness. Two experimental studies examine procedural and distributive fairness effects on overall price fairness. In study 1, procedural fairness and distributive fairness are manipulated and found to interact to bring about overall (...) price fairness. In study 2, suspicion toward the seller is found to mediate the relationship between procedural fairness and overall price fairness when the price is disadvantageous. (shrink)

Through a discussion of three pedagogical instances--based on classroom discourse, student writing, and program development--the authors examine education as an academic field, arguing that its disciplinary practices and perspectives invite interdisciplinarity and extra-disciplinarity to bridge from the academy to issues, problems, and strengths beyond it. Interdisciplinarity--understood as temporary “groundlessness”--emerges as a means to apprehend and respond to problems that in the context of past frustrations and failures may seem insurmountable; the willingness to not-know inspires new paradigms, experiences, and relationships. Extra-disciplinarity (...) highlights the many chords running between academe and the rest of the world. Using this framework, we discuss the featured pedagogical instances as small-scale models for changing the power structures that have historically silenced some perspectives and knowledges, thus opening these structures to new inputs and connections. We conclude that while this work has no guarantees and is never complete, we must keep trying to connect beyond our academic disciplines and ourselves, both to learn and to more effectively impact the world.

What do we mean when we say time passes? How do contingency and anachronism and other philosophical concepts bearing on time affect the more concrete realities of our political and cultural lives? In ways small and great, personal and cultural, we all experience the mutability of time. We feel it expand and contract, speed up and slow down, as it bends to the imperatives of memory, money, and the media. In our own time we have witnessed a disengagement with the (...) past even as technological advances have allowed us to capture and reproduce past time as never before. How are we to make sense of this paradox? In this wide-ranging meditation on the meaning of time, Sylvaine Agacinski weaves together discussions of Aristotle, Kant, Hegel, Freud, Heidegger, Baudelaire, Barthes, and especially Walter Benjamin -- her model for the modern "passer of time" -- as she traces a time line of the philosophy of time. After examining how shifting attitudes toward the passage of time have affected everything from art criticism to the development of photography to the rise of modernism itself, Agacinski concludes by proposing a rethinking of democracy that emphasizes patience in the face of our current temporal frenzy.

In lieu of an abstract, here is a brief excerpt of the content:On Sharing BreathJody Sperling (bio)My work as choreographer dwells on the inseparability between breath and atmosphere. There are no firm boundaries between the air we breathe in, the air surrounding us, and the air enveloping the planet. This is as true for air as it is for water—there is only one global ocean, although by convention we divide the seas into named regions. When you move through the ocean (...) of air enveloping you, you displace it and create dynamic unseen wakes in your midst.Beginning with my dance, "Turbulence" (2011),1 I sought to visualize such patterns of air disturbance into kinetic sculptural forms. To do so, the six dancers deployed Loie Fuller-style costumes, disquieting the air and materializing its gyrations. An early innovator of performance technology, Fuller danced in robes fashioned from hundreds of yards of silk with embedded wands that extended her body's motion into space. Serendipitously introduced to Fuller's work in 1997, I became seduced by the genre for the way it imbues the doer with an expanded sense of self. Whirling in the Fuller-style garments, I felt, and still feel, integrated into the atmosphere as an eddy or gust.With "Wind Rose" (2019),2 a collaboration with composer Matthew Burtner, I focused on making the connections between breath and wind palpable. Wind is said to be the breath of the planet, a driver of earthly life. A windrose is a meteorological tool that graphically represents wind speed, direction and variability at a particular time and place. I thought, what if I designed choreography with the intention not to create human motion, but in order to create a windrose—an atmospheric snapshot—in the performing space? At the start of "Wind Rose," the five dancers stand shoulder to shoulder and circle the stage so as to forge a human turbine. As the dancers accelerate their cyclonic motion, they push a swelling air wave towards the audience.For another section, I choreographed eight motions, each of which was connected with a sound. The sounds were made either by the dancers whipping their Fuller-style costumes through the air or by the dancers' breathy vocalizations. Matthew took my eight sound-breath-moves and composed a fugue. The dancers perform this music-motion score so that [End Page 155] they stir up a breeze pattern—a fugue that can be felt, as well as seen and heard.Wind has been changing along with climate. Locally, winds are becoming more chaotic. Globally, the high winds are slowing down and the polar jet stream is becoming wonky. But we are not in the habit of listening to the changing winds. One of the root causes of climate inaction has been a deep disconnect between people and their atmosphere. Many among the privileged live out their lives in climate-controlled habitats. Recently, though, even wealthy nations and the elite are starting to feel the heat. These days, no matter how deeply you bury your head in the sand, your butt will still get scorched.As a way of grappling with life in the Anthropocene, I have been formulating an open inquiry called ecokinetics. I conceived ecokinetics as a choreographic corollary to ecoacoustics, an environmental mode of music composition pioneered by Matthew Burtner, my long-time musical collaborator. According to Matthew, "ecoacoustics embeds environmental systems into musical and performance structures using new technologies" (Burtner). Ecokinetics asks, how can we relate human movement to environmental systems? How can choreography (aesthetically patterned human motion) illuminate, echo, expand upon the movement vectors present at a site and help us better understand local ecologies? How can dance entwine with media technologies to embody the processes of natural systems? Ecokinetics is part personal movement practice, part pedagogical tool, and part performance methodology.In its essence, ecokinetics repudiates the separation of humans from nature, a pervasive Colonialist mindset that needs constant undoing. In order to make progress on climate change, we must feel—truly and deeply—that we are part of the planet and not apart from it. This is the opposite of what the billionaires' space club aims to accomplish. Bezos, Branson, and Musk, et al. view distance from Earth as a... (shrink)

Jody Azzouni argues that we involuntarily experience certain physical items, certain products of human actions, and certain human actions themselves as having meaning-properties. We understand these items as possessing meaning or as having truth values. For example, a sign on a door reading "Drinks Inside" strikes native English speakers as referring to liquids in the room behind the door. The sign has a truth value--if no drinks are found in the room, the sign is misleading. Someone pointing in a (...) direction has the same effect: we experience her gesture as significant. Azzouni does not suggest that we don't recognize the expectations or intentions of speakers ; we do recognize that the person pointing in a certain direction intends for us to understand her gesture's significance. Nevertheless, Azzouni asserts that we experience that gesture as having significance independent of her intentions. The gesture is meaningful on its own. The same is true of language, both spoken and written. We experience the meanings of language artifacts as independent of their makers' intentions in the same way that we experience an object's shape as a property independent of the object's color. There is a distinctive phenomenology to the experience of understanding language, and Semantic Perception shows how this phenomenology can be brought to bear as evidence for and against competing theories of language.

In recent years, autopoietic enactivism has been used to address persistent conceptual problems in psychiatry, such as the problem of demarcating disorder, that other models thus far have failed to overcome. There appear to be three main enactive accounts of psychopathology with subtle, although not incompatible, differences: Maiesecharacterizes disorder as distinct disruptions in autonomy and agency; Nielsen characterizes disorder as behaviors that relevantly conflict with the functional norms of an individual; De Haan emphasizes patterns of disordered sense-making, that are transformed (...) through the existential dimension. Given that these accounts are intended to provide not only an ontologically richer account of psychopathology but also reduce the stigma experienced by individuals with mental disorders by accounting for lived experience, a critical analysis of these approaches is needed. I will provide a problematization of enactive accounts of mental disorder, showing that this particular framework does not, as it stands, necessarily reduce the harm and suffering experienced by individuals with mental disorder because of its ontological openness; enactivism leaves much to be interpreted and applied by the clinician (or patient) such that practical and ethical problems in its use arise.

Times of crisis bring about increased demands on businesses as shortages, or unexpected but significant, business costs are encountered. Passing on such costs to consumers is a challenge. When faced with a retail price increase, consumers may rely on cues as to the motive behind the increase. Such cues can raise suspicion of alternative motive (e. g., taking advantage of the consumer) affecting consumers' judgments of price fairness. This research investigates two triggers of suspicion: salience of alternative motives, and behavior (...) judged to be out-of-character for the business. Results of the two studies within crisis contexts indicate that suspicion is created when alternative motives are salient and when a retailer acts out-of-character. Multiple group analyses revealed that suspicion induced negative affect and subsequent perceptions of price fairness. When suspicion was present, more negative feelings toward the retailer and judgments of price unfairness resulted. (shrink)

Mistaken reasons for thinking diagrammatic proofs aren't rigorous are explored.

An additional (and independent) factor is treating the impossibility of naturally generalizing a diagrammatic proof procedure as an indication of (...) lack of rigor. (shrink)

A background assumption of this paper is that the repertoire of inference schemes available to humanity is not fixed, but subject to change as new schemes are invented or refined and as old ones are obsolesced or abandoned. This is particularly visible in areas like health and environmental sciences, where enormous societal investment has been made in finding ways to reach more dependable conclusions. Computational modeling of argumentation, at least for the discourse in expert fields, will require the possibility of (...) modeling change in a stock of schemes that may be applied to generate conclusions from data. We examine Randomized Clinical Trial, an inference scheme established within medical science in the mid-20th Century, and show that its successful defense by means of practical reasoning allowed for its black-boxing as an inference scheme that generates (and warrants belief in) conclusions about the effects of medical treatments. Modeling the use of a scheme is well-understood; here we focus on modeling how the scheme comes to be established so that it is available for use. (shrink)
