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.

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.

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.

Background Over the last decade, the return of results (ROR) in precision medicine research (PMR) has become increasingly routine. Calls for individual rights to research results have extended the “duty to report” from clinically useful genetic information to traits and ancestry results. ROR has thus been reframed as inherently beneficial to research participants, without a needed focus on who benefits and how. This paper addresses this gap, particularly in the context of PMR aimed at increasing participant diversity, by providing investigator (...) and researcher perspectives on and questions about the assumed value of ROR in PMR.Methods Semi-structured interviews with a purposive sample of investigators and researchers across federally funded PMR studies in three national consortia, as well as observations of study activities, focused on how PM researchers conceptualize diversity and implement inclusive practices across research stages, including navigating ROR.Results Interviewees (1) validated the value of ROR as a benefit of PMR, while others (2) questioned the benefit of clinically actionable results to individuals in the absence of sufficient resources for translating findings into health care for diverse and disadvantaged populations; (3) expressed uncertainties in applying the presumed value of ROR as a benefit for non-clinical results; and (4) and debated when the promise of the value of ROR may undermine trust in PMR, and divert efforts to return value beyond ROR.Conclusions Conceptualizations of diversity and inclusion among PM researchers and investigators raise unique ethical questions where unexamined assumptions of the value of ROR inform study recruitment efforts to enroll minoritized and under-represented populations. A lack of consideration for resources and infrastructure necessary to translate ROR into actionable information may hinder trustworthy community-research relationships. Thus, we argue for a more intentional interrogation of ROR practices as an offer of benefit and for whom. (shrink)

In this paper, Caitlin Murphy Brust and Rebecca Taylor examine the responsibilities of college educators to resist conditions of epistemic injustice within their institutions. Pedagogy alone cannot bring about epistemic justice in higher education, for no individual epistemic agent can single-handedly transform their epistemic environment. The roots of such injustices are structural and thus require structural interventions. However, college educators do retain some agency to engage in epistemic resistance. Brust and Taylor argue that they can and should take steps (...) to foster just relations within the epistemic communities of their classrooms — calling for pedagogy that both recognizes the unjust features of the broader epistemic environment and responds to the unique forms of epistemic injustice that manifest in the classroom, with particular attention to seminar-style courses.

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)

The articles in this issue of the Journal of Medicine and Philosophy explore emerging technologies, medical innovations, and shifting moral norms, expanding present discussions around topics in bioethics both old and new. Some question whether novel definitions of death and harm change the moral permissibility of killing, particularly at the hands of a physician. Others question how increased or decreased abilities affect responsibility and achievement. Another illustrates how rhetorical appeals to character have been used to justify otherwise morally illicit actions (...) within the clinic. Together, these articles shed new light on topics in the field of bioethics. (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)

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.

Detailed and in-depth investigation of the important but often unappreciated work done by science technicians, in this case in the context of paleontology.

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.

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. Over the years, philosophers of medicine and bioethicists have debated questions such as what qualifies something as a disease, whether disease language is evaluative, whether the term “person” encompasses more than just human beings, and what language ought to be used to (...) best convey complex information to patients. 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.

Reading is one of the most common everyday activities, yet research elucidating how affective influence reading processes and outcomes is sparse with inconsistent results. To investigate this question, we randomly assigned participants (N = 136) to happiness (positive affect), sadness (negative affect), and neutral video-induction conditions prior to engaging in self-paced reading of a long, complex science text. Participants completed assessments targeting multiple levels of comprehension (e.g. recognising factual information, integrating different textual components, and open-ended responses of concepts from memory) (...) after reading and after a week-long delay. Results indicated that the Sadness (vs. Happiness) condition had higher comprehension scores, with the largest effects emerging for assessments targeting deeper levels comprehension immediately after reading. Eye-tracking analyses revealed that such benefits may be partly driven by sustained attentional focus over the 20-minute reading session. We discuss results with respect to theories on affect, cognition, and text comprehension. (shrink)

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)

This paper defines and analyzes the processes of “othering” as they manifest in the practice and praxis of nursing education. Othering is bound up in the establishment and reinforcement of norms, and shores up power inequities that negatively impact faculty, students, and patients. While previous analyses have addressed othering in nursing more broadly, this paper adds a consideration of the multiple processes of othering that operate within the context of nursing education spaces. Cases from recent nursing education literature are interpreted (...) through the frameworks of exclusionary, inclusionary, and structural othering, and provide specific illustrations of the concepts described. The paper concludes by arguing for an application of norm‐critical pedagogical practice to counteract, disrupt and dismantle othering processes within nursing education. (shrink)

Across the globe, our work and social lives are increasingly integrated with Information and Communication Technologies, yet massive disparities in the values, uses and benefits of ICT exist. New methods are needed to shed light on unique and integrative concepts of ICT across cultures. This paper explores the use of visual methods to facilitate critical engagement with ICT—defined as situational awareness, reflexive ICT practice and power and control over ICT. This definition of critical ICT engagement is informed by a cultural (...) identity lens, and intends to improve participatory methods in ICT for Development and community technology design and application. Our notion of critical ICT engagement is developed through an analysis of three case studies, each employing visual methods to shed light on concepts and practices of ICT cross-culturally. This paper makes three contributions to the ICT4D literature. First, it establishes a cultural identity lens to chart out cultural differences between researchers and participants, and to develop situational awareness of ICT in context. Second, it defines the conceptual domain of reflexive ICT practice and establishes the key role of researchers in facilitating it. Third, it argues for the need to support participants to develop capacity to engage critically with ICT as a means to influence social and organizational structures. This paper offers a way for researchers and practitioners to engage with cultural issues in community-based research and design using visual methodologies. (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.

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)

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)

Museum displays tend to black-box science, by displaying scientific facts without explanations of how those facts were made. A recent trend in exhibit design upends this omission by putting scientists, technicians, and volunteers to work in glass-walled laboratories, just a window away from visitors. How is science conceived, portrayed, and performed in glass-walled laboratories? Interviews and participant observation in several “fishbowl” paleontology laboratories reveal that glass walls alter lab workers’ typical tasks and behavior. However, despite glass-walled labs’ incomplete and edited (...) enactment of scientific work, displaying an active workplace valuably challenges visitors’ assumptions that science is passive and that museums are home only to facts and dead things. Thus, glass-walled labs do not destroy the black box that obscures scientific practice for nonscientists. Instead, they exemplify a glass box, a kind of black box that contains a performance of scientific work. Glass-boxing describes a common way in which museums present scientific practice—that is, by making it observable but incompletely so—by inviting the public to construct a rich understanding of science as human work.

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.

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.

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.
