Human development takes place in a social context. Two pervasive sources of social information are faces and hands. Here, we provide the first report of the visual frequency of faces and hands in the everyday scenes available to infants. These scenes were collected by having infants wear head cameras during unconstrained everyday activities. Our corpus of 143 hours of infant-perspective scenes, collected from 34 infants aged 1 month to 2 years, was sampled for analysis at 1/5 Hz. The major finding (...) from this corpus is that the faces and hands of social partners are not equally available throughout the first two years of life. Instead, there is an earlier period of dense face input and a later period of dense hand input. At all ages, hands in these scenes were primarily in contact with objects and the spatio-temporal co-occurrence of hands and faces was greater than expected by chance. The orderliness of the shift from faces to hands suggests a principled transition in the contents of visual experiences and is discussed in terms of the role of developmental gates on the timing and statistics of visual experiences.

Philosophers of science are well aware that theories are underdetermined by data. But what about the data? Scientific data are selected and processed representations or pieces of nature. What is useless context and what is valuable specimen, as well as how specimens are processed for study, are not obvious or predetermined givens. Instead, they are decisions made by scientists and other research workers, such as technicians, that produce different outcomes for the data. Vertebrate fossils provide a revealing case of this (...) data-processing, because they are embedded in rock that often matches the fossils’ color and texture, requiring an expert eye to judge where the fossil/context interface is. Fossil preparators then permanently define this interface by chiseling away the material they identify as rock. As a result, fossil specimens can emerge in multiple possible forms depending on the preparator’s judgment, skill, and chosen tools. A prepared fossil then is not yet data but potential data, following Leonelli’s relational framework in which data are defined as evidence that scientists have used to support a proposed theory. This paper draws on ethnographic evidence to assess how scientists overcome this underdetermination of specimens, as potential data, in addition to the underdetermination of theories and of data, to successfully construct specimen-based knowledge. Among other strategies, paleontology maintains a division of labor between data-makers and theory-makers. This distinction serves to justify the omission of preparators’ nonstandard, individualized techniques from scientific publications. This separation has benefits for both scientists and technicians; however, it restricts knowledge production by preventing scientists from understanding how the pieces of nature they study were processed into researchable specimens.

Despite being neighbouring countries, Bolivia and Argentina appear to be a world apart in terms of economics, international relations, and women’s rights. Historically, women’s rights have been fairly similar in both countries, but while one country seemingly made “progress,” the other country appeared to be stagnating. By exploring violence against women, and the current state of contraception and abortion laws it becomes apparent that “progress” does not necessarily bring about social change.

PurposeThe ability to hear ourselves speak has been shown to play an important role in the development and maintenance of fluent and coherent speech. Despite this, little is known about the developing speech motor control system throughout childhood, in particular if and how vocal and articulatory control may differ throughout development. A scoping review was undertaken to identify and describe the full range of studies investigating responses to frequency altered auditory feedback in pediatric populations and their contributions to our understanding (...) of the development of auditory feedback control and sensorimotor learning in childhood and adolescence.MethodRelevant studies were identified through a comprehensive search strategy of six academic databases for studies that included real-time perturbation of frequency in auditory input, an analysis of immediate effects on speech, and participants aged 18 years or younger.ResultsTwenty-three articles met inclusion criteria. Across studies, there was a wide variety of designs, outcomes and measures used. Manipulations included fundamental frequency, formant frequency, frequency centroid of fricatives, and both fundamental and formant frequencies. Study designs included contrasts across childhood, between children and adults, and between typical, pediatric clinical and adult populations. Measures primarily explored acoustic properties of speech responses. Some studies additionally examined the association of these acoustic responses with clinical measures, and neural measures using electrophysiology and magnetic resonance imaging.ConclusionFindings indicated that children above 4 years generally compensated in the opposite direction of the manipulation, however, in several cases not as effectively as adults. Overall, results varied greatly due to the broad range of manipulations and designs used, making generalization challenging. Differences found between age groups in the features of the compensatory vocal responses, latency of responses, vocal variability and perceptual abilities, suggest that maturational changes may be occurring in the speech motor control system, affecting the extent to which auditory feedback is used to modify internal sensorimotor representations. Varied findings suggest vocal control develops prior to articulatory control. Future studies with multiple outcome measures, manipulations, and more expansive age ranges are needed to elucidate findings. (shrink)

Over the past decade, Canadian media coverage of street sex work has steadily increased. The majority of this interest pertains to graphic violence against street sex workers, most notably from Vancouver, British Columbia. In this article, the authors analyze newspaper coverage that appeared in western Canadian publications between 2006 and 2009. In theorizing the violence both depicted and perpetrated by newspapers, the authors propose an analytic framework capable of attending to the process of othering in all of its complexity. To (...) this end, the authors supplement a Foucauldian analysis of abjection by considering the work of Judith Butler along with Julia Kristeva's conceptualization of abjection. Using excerpts from western Canadian newspapers, the authors illustrate how the media's discursive practices function as triggers for the process of cultural abjection by inscribing street sex workers with images of defilement. The authors argue that newspaper coverage of street sex workers reinforces the inviolability of normalized life by constantly reiterating the horror reserved for abjected bodies. (shrink)

This multidisciplinary book brings together a series of critical engagements regarding the notion of ethical practice. As a whole, the book explores the question of how the current neo-liberal socio-political moment, and its relationship to the historical legacies of colonialism, white settlement, and racism, informs and shapes our practices, pedagogies, and understanding of encounters in diverse settings. Drawing largely on the work of Sara Ahmed’s Strange Encounters: Embodied Others in Post-Coloniality, each chapter in this book takes up a particular encounter (...) and unravels the elements that created these meetings in specific times and spaces. Sites of encounters included in this volume range from the classroom to social work practice and from literary to media interactions, and take place both within Canada and internationally. Paramount to the discussions is a consideration of how relations of power and legacies of oppression shape self and others, and draw boundaries between bodies within an encounter. From a social justice perspective, Unravelling Encounters exposes the political conditions that configure our meetings with one another, and inquires into what it means to care, to respond, and to imagine oneself as an ethical subject.

Globally, one in eight people lacks access to potable water; more people die from unsafe drinking water than from all forms of violence, including war. A substantial body of research documents that the privatization of water – led by global financial institutions working in collusion with governments and corporations – does not lead to more people gaining access to safe water. In fact, the opposite is true: privatization leads to both higher cost and lower quality water. For the past century, (...) the dominant focus of transnational organizing has been “from the West to the rest,” and the frequent attention to movements in the global North has led to the neglect of transnational linkages between movements. Drawing on fieldwork conducted on three right to water movements that span three continents, this paper examines effortsto reclaim the water commons,and how struggles have been driven by grassroots movements demanding that democracy, transparency, and the human right to water are prioritized over corporate profit. As feminist scholars have pointed out, the “standpoint” offered by marginalized actors offers important insights into the operation of systems of power and the strategies of survival and resistance that less powerful actors adopt in order to survive and thrive. This paper explores how transnational movements around water and other basic rights engage with and learn from each other. (shrink)

The amygdala is a key brain area regulating responses to stress and emotional stimuli, so improving our understanding of how it is regulated could offer novel strategies for treating disturbances in emotion regulation. As we review here, a growing body of evidence indicates that the gut microbiota may contribute to a range of amygdala-dependent brain functions from pain sensitivity to social behavior, emotion regulation, and therefore, psychiatric health. In addition, it appears that the microbiota is necessary for normal development of (...) the amygdala at both the structural and functional levels. While further investigations are needed to elucidate the exact mechanisms of microbiota-to-amygdala communication, ultimately, this work raises the intriguing possibility that the gut microbiota may become a viable treatment target in disorders associated with amygdala dysregulation, including visceral pain, post-traumatic stress disorder, and beyond. Also see the video abstract here: https://youtu.be/O5gvxVJjX18 The amygdala plays a central role in regulating many aspects of behavior in rodents and humans, from pain responding to social interaction and psychiatric function. Accumulating evidence suggests microbiota-to-amygdala communication along the gut-brain axis is a key modulator of these amygdala-dependent behaviors, with critical implications for health and disease.

The purpose of this paper is to examine the linkages and relationships between the officially prescribed school ethos and that which emerges from social interaction. Qualitative data drawn from one Grant-Maintained-Integrated and one Catholic primary school in Northern Ireland show how school ethos, defined as the observed practices and interactions of school members, often departs considerably from school ethos defined as those values and beliefs which the school officially supports. On the basis of the data it is argued that much (...) of what we understand of school ethos is superficial and contradictory. With this in mind the paper concludes by presenting a new angle on ethos which, when taken in conjunction with the other perspectives, further enhances our understanding of how schools work.

A major challenge in neuroscience is to understand what happens to a brain as it ages. Such insights could make it possible to distinguish between individuals who will undergo typical aging and those at risk for neurodegenerative disease. Over the last quarter century, thousands of human brain imaging studies have probed the neural basis of age-related cognitive decline. “Aging” studies generally enroll adults over the age of 65, a historical precedent rooted in the average retirement age of U.S. wage-earners. A (...) consequence of this research tradition is that it overlooks one of the most significant neuroendocrine changes in a woman’s life: the transition to menopause. The menopausal transition is marked by an overall decline in ovarian sex steroid production – up to 90% in the case of estradiol – a dramatic endocrine change that impacts multiple biological systems, including the brain. Despite sex differences in the risk for dementia, the influence that biological sex and sex hormones have on the aging brain is historically understudied, leaving a critical gap in our understanding of the aging process. In this Perspective, we highlight the influence that endocrine factors have on the aging brain. We devote particular attention to the neural and cognitive changes that unfold in the middle decade of life, as a function of reproductive aging. Next, we consider emerging evidence from animal and human studies that other endocrine factors occurring earlier in life (e.g. pregnancy, hormonal birth control use) also shape the aging process.

In this paper, Caitlin Murphy Brust and Hannah Widmaier begin with the assumption that highly selective institutions of higher education in the United States have a duty to promote civic equality. They employ Wendy Salkin's theory of informal political representation to examine how highly selective institutions should go about promoting civic equality. According to Salkin's theory, someone serves as an informal political representative (IPR) when they speak or act on behalf of others, without having been selected to do so (...) via a systematized selection procedure. Brust and Widmaier argue that as part of their civic educational missions, highly selective institutions should educate their students for informal political representation, and this includes equipping students to (1) serve as effective IPRs, (2) be responsible audience members to others' informal political representation, and (3) deliberate carefully and with open-mindedness about when they should or should not take on the role of IPR. Brust and Widmaier examine two types of injustice that students from marginalized communities face at highly selective institutions, and they explore how education for informal political representation might ameliorate those injustices. The authors conclude by offering some practical suggestions to institutional policymakers and educators. (shrink)

Occupy Wall Street, Indignés, Nuit Debout - plus que jamais la question est posée de définir la vie que nous souhaitons choisir et vivre. Une vie vécue est inséparable de ses formes, de ses modalités, de ses régimes, de ses gestes, de ses façons, de ses allures... qui sont déjà des idées. Le monde, tel que nous le partageons et lui donnons sens, ne se découpe pas seulement en individus, en classes ou en groupes, mais aussi en "styles", qui sont (...) autant de phrasés du vivre, animé de formes attirantes ou repoussantes, habitables ou inhabitables, c'est-à-dire de formes qualifiées : des formes qui comptent, investies de valeurs et de raisons d'y tenir, de s'y tenir, et aussi bien de les combattre. C'est sur ce plan des formes de la vie que se formulent aujourd'hui beaucoup de nos attentes, de nos revendications, et surtout de nos jugements. C'est toujours d'elles que l'on débat, et avec elles ce sont des idées complètes du vivre que l'on défend ou que l'on accuse. Une forme de vie ne s'éprouve que sous l'espèce de l'engagement, là où toute existence, personnelle ou collective, risque son idée. Vouloir défendre sa forme de vie, sans tapage, en la vivant, mais aussi savoir en douter et en exiger de tout autres, voilà à quoi l'histoire la plus contemporaine redonne de la gravité. Bien au-delà du champ de l'art, Marielle Macé propose la construction critique d'une véritable stylistique de l'existence. Cela suppose de s'intéresser sans préjugé à tout ce qu'engagent les variations formelles de la vie sur elle-même - styles, manières, façons - et de ne pas traiter forcément de vies éclatantes, triomphantes, d'apparences prisées ou de corps élégants. Ce n'est pas seulement la littérature mais bien toutes les sciences humaines qui, pour comprendre le monde immédiat, sous nos yeux, doivent s'y rendre vraiment attentives. (shrink)

The disciplines of ethics, science, and the law often conflict when it comes to determining the limits and boundaries of embryo research. Under current Australian law and regulations, and in various other jurisdictions, research conducted on the embryo in vitro is permitted up until day fourteen, after which, the embryo must be destroyed. Reproductive technology and associated research is rapidly advancing at a rate that contests current societal and ethical limits surrounding the treatment of the embryo. This has brought about (...) the question of the adequacy of the fourteen-day rule and whether it is necessary for it be reconsidered and reformed. This paper will highlight some of the tensions that exist in ethics, science, and the law in relation to the extension of the rule. It will be concluded that any move to extend the rule must be accompanied by close consultation with the public as the ultimate stakeholders in how the future of reproductive technology is created, constructed, and contested.

In mining, manufacturing and industrial process industries, maintenance procedures are used as an aid to guide technicians through complex manual tasks. These procedures are not machine-readable, and cannot support reasoning in digitally integrated manufacturing systems. Procedure documents contain unstructured text and are stored in a variety of formats. The aim of this work is to query information held in real industrial maintenance procedures. To achieve this, we develop an ontology for maintenance procedures using the OWL 2 description language. We leverage (...) classes and object properties from the ISO 15926 Part 14 Upper Ontology and create a domain ontology. The key contribution of this paper is a demonstration of trade-offs required when modelling an existing engineering artifact, where an abstraction of its contents is given a-priori. We provide an ontologically rigorous abstraction of notions captured in procedure documentation to a set of classes, relations and axioms that allow reasoning over the contents. Validation of the ontology is performed via a series of competency questions based on queries relevant to technicians, engineers and schedulers in industry. The ontology is applied to real world maintenance procedures from two industrial organisations. (shrink)

The Ainu are still in existence, but their reduced numbers, now around 20,000, indicate how marginal their presence is even in Hokkaido, their ancestral territory. Moreover, they have undergone much metissage, in both ethnic and cultural terms.

In 1994, for the first time in history, an (...) Ainu, Kay ano Shigeru, was elected to the senate. The legislation concerning the Ainu lands, dating from 1899, has finally been revised.

BackgroundUniversal standards for bioethics, including the tenet of informed consent, should be upheld in the setting of humanitarian medical missions. The obstacles to obtaining informed consent in the global health setting have been thoroughly discussed in the literature, but no studies have investigated these issues from the patient’s perspective.

There is a longstanding belief that research should be a calling more than a job. How does this expectation shape the selection of future researchers? Specifically, undergraduate research experience is credited with increasing students’ success in science and engineering majors and their likelihood to choose careers in science and engineering; thus, how researchers select student laboratory workers has implications for the future population of researchers. After all, because research communities construct knowledge collectively, researchers’ identities and experiences crucially shape knowledge. This (...) paper analyzes qualitative interviews with engineering professors and students about what they believe are the characteristics of a good researcher. Both groups describe the importance of a researcher feeling interested in and enthusiastic about research to be able to do good work. They also imply that good researchers must be assertive, such as by requesting jobs in laboratories. I suggest that these... (shrink)

Doubt is a much-maligned state. We are racked by doubts, tormented by doubts, plagued by them, paralysed. Doubts can be troubling, consuming, agonising. But however ill-regarded is doubt, anxiety is more so. We recognise the significance of doubting in certain contexts, and allow ourselves to be guided by our doubts. For example, the criminal standard of proof operative in the U.K., U.S., as well as in most other anglophone countries, Germany, Italy, Sweden and Israel, requires for conviction to be permissible (...) that the defendant’s guilt is proved beyond reasonable doubt; to feel a doubt about a defendant’s guilt, so long as it is reasonable, is reason to refrain from convicting. But our folk understanding of anxiety ascribes no value to that state. Anxiety is inherently unpleasant and irrational; it prevents us from being able to perform well when it is most important to us that we do; it is an emotion that, if we could, we’d eliminate from our emotional toolbox. Yet in this thesis, I offer a vindication of doubt – a defence of doubt in terms of what it does for us – on which it ultimately turns out to be a kind of anxiety. The basic idea is that the concept of doubt serves a function for us that we couldn’t do without: it signals when we should begin inquiry. I will argue that the concept doubt is able to serve this function because the state it picks out, the state of doubt, is a kind of anxiety: epistemic anxiety. I develop a picture of epistemic anxiety as an emotional response to epistemic risk: potential disvalue in the epistemic realm. Because doubt is a kind of anxiety, it has the right kind of representational and motivational profile to track epistemic risk in our environments, and motivate us to reduce or avoid that risk. This makes it hugely valuable for us, as knowledge-seeking creatures, given the incompatibility of knowledge with high levels of epistemic risk. (shrink)

The authors of the articles in this issue of The Journal of Medicine and Philosophy address a wide variety of topics, from definitions of disease to bioenhancement. Each author, however, draws out the importance of careful use of language.

Among a great deal of disagreement on these topics, one thing emerges distinctly: that clarity and careful attention to language is paramount in medicine. The articles in this issue contribute to that conversation, presenting complex arguments and illustrative examples of why it is so important to use clear and well-defined terms in medicine, and of the reality-altering power that our language carries.

A research community must share assumptions, such as about accepted knowledge, appropriate research practices, and good evidence. However, community members also hold some divergent assumptions, which they—and we, as analysts of science—tend to overlook. Communities with different assumed values, knowledge, and goals must negotiate to achieve compromises that make their conflicting goals complementary. This negotiation guards against the extremes of each group’s desired outcomes, which, if achieved, would make other groups’ goals impossible. I argue that this diversity, as a form (...) of value pluralism, regularly influences scientific practice and can make scientific evidence and knowledge more useful and more reliable. As an example, I examine vertebrate paleontology laboratories, which house a variety of workers with different training and priorities, particularly about the meaning of time. Specifically, scientists want to study fully prepared fossils immediately, conservators want to preserve fossils for future use, and preparators mediate between the other groups’ conflicting goals. After all, one cannot study a fossil encased in rock, and one cannot remove that rock without removing information from that specimen. In response, these coworkers articulate their assumptions in everyday deliberations about how scientific evidence should be made and used. I argue that this exchange of assumptions is crucial for a research community to achieve mutually beneficial compromises that benefit current and future knowledge construction. (shrink)

Background Nigeria is an emerging hub of biomedical research, requiring additional trained bioethicists for ethical oversight of research studies. There are currently two graduate-level health research ethics programs in Nigeria. However, both are in the southern part of the country and no such training programs exist in the north. Strengthening the health research ethics skills and knowledge of Nigerian researchers across the country is necessary given the growing genetics research infrastructure. Methods To inform the creation of a Master of Science (...) in Health Research Ethics program in northern Nigeria, we conducted a needs assessment comprised of semi-structured interviews with nine Nigerian bioethics experts. We used the Interpretative Phenomenological Analysis (IPA) method to analyze interview transcriptions. Two authors independently read and coded each respondent’s transcript to identify emergent themes that represented each respondent’s answers. Within these overarching themes, the data points were grouped into subthemes. Results Four primary themes emerged with ten subthemes. Respondents believed that the program can fill a gap and strengthen capacity in health research ethics. They emphasized that the curriculum should be developed with an interdisciplinary lens and locally contextualized, and that students should be taught how to think critically through ethical scenarios. Respondents stressed that program leaders should recruit faculty and students locally who have the bandwidth to participate in the program. Finally, respondents noted the program should have university support to be sustainable. Conclusion Our findings will guide the creation of a master’s degree program that aims to build capacity in health research ethics in northern Nigeria and enhance the country’s growing prominence in global biomedical research. Through our needs assessment, we identified structural and content factors that can guide us in leveraging the strengths of the local institution and leaders in health research ethics while mitigating challenges in establishing this program.

BackgroundReturning neuroimaging incidental findings may create a challenge to research participants’ health literacy skills as they must interpret and make appropriate healthcare decisions based on complex radiology jargon. Disclosing IF can therefore present difficulties for participants, research institutions and the healthcare system. The purpose of this study was to identify the extent of the health literacy challenges encountered when returning neuroimaging IF. We report on findings from a retrospective survey and focus group sessions with major stakeholders involved in disclosing IF.MethodsWe (...) surveyed participants who had received a radiology report from a research study and conducted focus groups with participants, parents of child participants, Institutional Review Board members, investigators and physicians. Qualitative thematic analyses were conducted using standard group-coding procedures and descriptive summaries of health literacy scores and radiology report outcomes are examined.ResultsAlthough participants reported high health literacy skills, 67 % did not seek medical care when recommended to do so; and many participants in the focus groups disclosed they could not understand the findings described in their report. Despite their lack of understanding, participants desire to have information about their radiology results, and the investigators feel ethically inclined to return findings.ConclusionsThe language in clinically useful radiology reports can create a challenge for participants’ health literacy skills and has the potential to negatively impact the healthcare system and investigators conducting imaging research. Radiology reports need accompanying resources that explain findings in lay language, which can help reduce the challenge caused by the need to communicate incidental findings. (shrink)

New technologies can upset scientific workplaces’ established practices and social order. Scientists may therefore prefer preserving skilled manual work and the social status quo to revolutionary technological change. For example, digital imaging of rock-encased fossils is a valuable way for scientists to “see” a specimen without traditional rock removal. However, interviews in vertebrate paleontology laboratories reveal workers’ skepticism toward computed tomography imaging. Scientists criticize replacing physical fossils with digital images because, they say, images are more subjective than the “real thing.” (...) I argue that these scientists are also implicitly supporting rock-removal technicians, who are skilled and trusted experts whose work would be made obsolete by widespread implementation of CT scanning. Scientists’ view of CT as a sometimes useful tool rather than a universal new approach to accessing fossils preserves the laboratory community’s social structure. Specifically, by privileging “real” specimens and trusted specimen-processing technicians over images and imaging experts, scientists preserve the lab community’s division of labor and skill, hierarchy between scientists and technicians, and these groups’ identity and mutual trust.

How do children acquire beliefs from testimony? In this chapter, we discuss children's trust in testimony, their sensitivity to and use of defeaters, and their appeals to positive reasons for trusting what other people tell them. Empirical evidence shows that, from an early age, children have a tendency to trust testimony. However, this tendency to trust is accompanied by sensitivity to cues that suggest unreliability, including inaccuracy of the message and characteristics of the speaker. Not only are children sensitive to (...) evidence of unreliability, but they are also sensitive to the positive reasons a speaker may have for the reliability of their testimony. This evidence is discussed in relation to reductivist and non-reductivist viewpoints. (shrink)
