Pathogenesis in tauopathies involves the accumulation of tau in the brain and progressive synapse loss accompanied by cognitive decline. Pathological tau is found at synapses, and it promotes synaptic dysfunction and memory deficits. The specific role of toxic tau in disrupting the molecular networks that regulate synaptic strength has been elusive. A novel mechanistic link between tau toxicity and synaptic plasticity involves the acetylation of two lysines on tau, K274, and K281, which are associated with dementia in Alzheimer's disease (AD). (...) We propose that an increase in tau acetylated on these lysines blocks the expression of long‐term potentiation at hippocampal synapses leading to impaired memory in AD. Acetylated tau could inhibit the activity‐dependent recruitment of postsynaptic AMPA‐type glutamate receptors required for plasticity by interfering with the postsynaptic localization of KIBRA, a memory‐associated protein. Strategies that reduce the acetylation of tau may lead to effective treatments for cognitive decline in AD. (shrink)

ABSTRACT This essay considers the implications of a shift in focus from ideas to practices in the history of alchemy. On the one hand, it is argued, this new attention to practice highlights the diversity of ways that early modern Europeans engaged alchemy, ranging from the literary to the entrepreneurial and artisanal, as well as the broad range of social and cultural spaces that alchemists inhabited. At the same time, however, recent work has demonstrated what most alchemists shared—namely, a penchant (...) for reading, writing, making, and doing, all at the same time. Any history of early modern alchemy, therefore, must attend to all of these practices, as well as the interplay among them. In this sense, alchemy offers a model for thinking and writing about early modern science more generally, particularly in light of recent work that has explored the intersection of scholarly, artisanal, and entrepreneurial forms of knowledge in the early modern period.

Respecting patient autonomy through the process of soliciting informed consent is a cornerstone of clinical ethics. In pediatrics, until a child becomes an adult or legally emancipated, that ethical tenet takes the form of respect for parental decision-making authority. In instances of respecting religious beliefs, doing so is not always apparent and sometimes the challenge lies not only in the healthcare provider’s familiarity of religious restrictions but also their knowledge of medical interventions themselves which might conflict with those restrictions. We (...) examine a case of a newborn receiving animal-derived surfactant, a common scenario in neonatology, and present considerations for providers to weigh when confronting when such an intervention might conflict with parent’s religious beliefs. We end with strategizing ways to address this issue as a medical community. (shrink)

Four studies explore the role of perceptual fluency in attenuating bullshit receptivity, or the tendency for individuals to rate otherwise meaningless statements as “profound”. Across four studies, we presented participants with a sample of pseudoprofound bullshit statements in either a fluent or disfluent font and found that overall, disfluency attenuated bullshit receptivity while also finding little evidence that this effect was moderated by cognitive thinking style. In all studies, we measured participants’ cognitive reflection, need for cognition, faith in intuition, and (...) superstitious beliefs. Superstition strongly predicted bullshit receptivity regardless of fluency. Inconclusive results were found for the remaining scales. Potential links for the role of perceptual disfluency in promoting analytic thinking are discussed. (shrink)

This essay considers how scholarly approaches to the development of molecular biology have too often narrowed the historical aperture to genes, overlooking the ways in which other objects and processes contributed to the molecularization of life. From structural and dynamic studies of biomolecules to cellular membranes and organelles to metabolism and nutrition, new work by historians, philosophers, and STS scholars of the life sciences has revitalized older issues, such as the relationship of life to matter, or of physicochemical inquiries to (...) biology. This scholarship points to a novel molecular vista that opens up a pluralist view of molecularizations in the twentieth century and considers their relevance to current science. (shrink)

Many people appear to attach great value to sad music. But why? One way to gain insight into this question is to turn away from music and look instead at why people value sad conversations. In the case of conversations, the answer seems to be that expressing sadness creates a sense of genuine connection. We propose that sad music can also have this type of value. Listening to a sad song can give one a sense of genuine connection. We then (...) explore the nature of this value in two experimental studies. The results suggest a striking relationship between music and conversation. People see something distinctively musical in works that express precisely those emotions that they think most create connection within conversation. (shrink)

Health equity is a global concern. Although health equity extends far beyond the equitable distribution of healthcare, equitable access to healthcare is essential to the achievement of health equity. In Canada, Indigenous Peoples experience inequities in health and healthcare access. Cultural safety and trauma‐ and violence‐informed care have been proposed as models of care to improve healthcare access, yet practitioners lack guidance on how to implement these models. In this paper, we build upon an existing framework of equity‐oriented care for (...) primary healthcare settings by proposing strategies to guide nurses in operationalizing cultural safety and trauma‐ and violence‐informed care into nursing practice at the individual level. This component is one strategy to redress inequitable access to care among Indigenous Peoples in Canada. We conceptualize barriers to accessing healthcare as intrapersonal, interpersonal, and structural. We then define three domains for nursing action: practicing reflexivity, prioritizing relationships, and considering the context. We have applied this expanded framework within the context of Indigenous Peoples in Canada as a way of illustrating specific concepts and focusing our argument; however, this framework is relevant to other groups experiencing marginalizing conditions and inequitable access to healthcare, and thus is applicable to many areas of nursing practice.

Inequities in access to oncology care among Indigenous peoples in Canada are well documented. Access to oncology care is mediated by a range of factors; however, emerging evidence suggests that healthcare providers, including nurses, play a significant role in shaping healthcare access. The purpose of this study was to critically examine access to oncology care among Indigenous peoples in Canada from the perspective of oncology nurses. Guided by postcolonial theoretical perspectives, interpretive descriptive and critical discourse analysis methodologies informed study design (...) and data analysis. Oncology nurses were recruited from across Canada to complete an online survey (n = 78). Nurses identified a range of barriers experienced by Indigenous peoples when accessing oncology care, yet located these barriers primarily at the individual and systems levels. Nurses perceived themselves as mediators of access to oncology care; however, their efforts to facilitate access to care were constrained by the dominance of biomedicine within healthcare. Nurses' constructions of access to oncology care highlight the embedded narrative of individualism within nursing practice and the relative invisibility of racism as a determinant of equitable access to care among Indigenous peoples. This suggests a need for oncology nurses to better understand and incorporate structural determinants of health perspectives. (shrink)

As nursing professionals, we believe access to healthcare is fundamental to health and that it is a determinant of health. Therefore, evidence suggesting access to healthcare is problematic for many Indigenous peoples is concerning. While biomedical perspectives underlie our current understanding of access, considering alternate perspectives could expand our awareness of and ability to address this issue. In this paper, we critique how access to healthcare is understood through a biomedical lens, how a postcolonial theoretical lens can extend that understanding, (...) and the subsequent implications this alternative view raises for the nursing profession. Drawing on peer‐reviewed published and gray literature concerning healthcare access and Indigenous peoples to inform this critique, we focus on the underlying theoretical lens shaping our current understanding of access. A postcolonial analysis provides a way of understanding healthcare as a social space and social relationship, presenting a unique perspective on access to healthcare. The novelty of this finding is of particular importance for the profession of nursing, as we are well situated to influence these social aspects, improving access to healthcare services broadly, and among Indigenous peoples specifically.

Coral bleaching has impacted reefs worldwide and the predictions of near‐annual bleaching from over two decades ago have now been realized. While technology currently provides the means to predict large‐scale bleaching, predicting reef‐scale and within‐reef patterns in real‐time for all reef users is limited. In 2020, heat stress across the Great Barrier Reef underpinned the region's third bleaching event in 5 years. Here we review the heterogeneous emergence of bleaching across Heron Island reef habitats and discuss the oceanographic drivers that (...) underpinned variable bleaching emergence. We do so as a case study to highlight how reef end‐user groups who engage with coral reefs in different ways require targeted guidance for how, and when, to alter their use of coral reefs in response to bleaching events. Our case study of coral bleaching emergence demonstrates how within‐reef scale nowcasting of coral bleaching could aid the development of accessible and equitable bleaching response strategies on coral reefs.

The aim of this study was to understand how incivility is viewed across multiple academic programs and respondent subgroups where different institutional and cultural power dynamics may influence the way students and faculty perceive uncivil behaviors. This study used the Conceptual Model for Fostering Civility in Nursing Education as its guiding framework. The Incivility in Higher Education Revised (IHE-R) Survey and a detailed demographic questionnaire were used to gather self-assessment and personal perspective data regarding incivility in the higher education setting. (...) This approach aspired to collect a comprehensive perspective of incivility in higher education. With data from 400 students and 69 faculty, there was limited agreement between faculty and student participants about perceptions and experiences with incivility. Faculty and students did agree that the solution to incivility may be found with the creation of a code of conduct that defines acceptable and unacceptable behavior, role-modeling professionalism and civility, and taking personal responsibility and standing accountable for actions. Despite significant differences in participants’ perceptions of incivility, they shared common solutions. With a shared goal, faculty and students can work toward cultivating civility in higher education. (shrink)

Recognizing gaps in our present understanding of leader apologies, this investigation examines how followers appraise leader apologies and how these perceptions impact work-related outcomes. Results indicate that followers who viewed their leader as trustworthy or caring before a leader wrongdoing were more likely to perceive their leader’s apology to be sincere, as compared to followers who previously doubted their leader’s trustworthiness and caring. Attributions of apology sincerity affected follower reactions, with followers perceiving sincere apologies reporting greater trust in leadership, satisfaction (...) with supervision, leader–member exchange quality, affective organizational commitment, and forgiveness than those reporting insincere or no apologies. A mediation model was supported, showing that attributions of apology sincerity fostered perceptions of humility, which enhanced perceptions of transformational leadership, and consequently garnered more positive follower reactions.

Visual representation of instruments and musical practice has long been integral to the study of the iconology and archaeology of early music. Critical to any assessment of such evidence is an understanding of the authority of the artist, and his/her knowledge and degree of participation in musical culture. Contemporary sources reveal that music played a variety of roles in the lives and public perception of the Renaissance artists. Its most tangible manifestation was that of the artist-musician, of whom Leonardo da (...) Vinci is one of the best-known examples. An association with courtliness was one of several markers of status conferred by musical practice. This chapter investigates the domestic setting of the artist, whether in a courtly environment or in a republic, to develop themes of the social elevation of the artist, entertainment and performance, as well as creativity.

Responding to mounting public concern about the shift to managed care, legislation to grant patient protections has dominated the health policy agenda over the past two years. Although some policies, such as laws on maternity length of stay, can be easily dismissed as “body part by body part” micromanagement of medical practice, other initiatives offer substantive, new rights to patients across the spectrum of care. At both the state and the federal levels, the right of enrollees to appeal a denial (...) of treatment or to file grievances about other plan decisions has emerged as a centerpiece of patient protection legislation. Grievance and appeal rights have been embraced as a way to empower patients, to enhance access to treatment, and to improve the quality of care by providing an external mechanism to review treatment denials.

Plant-based milk alternatives–or mylks–have surged in popularity over the past ten years. We consider the politics and consumer subjectivities fostered by mylks as part of the broader trend towards ‘plant-based’ food. We demonstrate how mylk companies inherit and strategically deploy positive framings of milk as wholesome and convenient, as well as negative framings of dairy as environmentally damaging and cruel, to position plant-based as the ‘better’ alternative. By navigating this affective landscape, brands attempt to make mylk as simultaneously palatable and (...) disruptive to the status quo. We examine the politics of mylks through the concept of palatable disruption, where people are encouraged to care about the environment, health, and animal welfare enough to adopt mylks but to ultimately remain consumers of a commodity food. By encouraging consumers to reach for “plant-based” as a way to cope with environmental catastrophe and a life out of balance, mylks promote a neoliberal ethic: they individualize systemic problems and further entrench market mechanisms as solutions, thereby reinforcing the political economy of industrial agriculture. In conclusion, we reflect on the limits of the current plant-based trend for transitioning to more just and sustainable food production and consumption. (shrink)

This study aims to better understand the perceptions and experiences related to incivility by students and faculty across multiple academic programs and respondent subgroups at a regional university in the southern United States. The study used a thematic analysis to examine student and faculty responses to three qualitative questions that focused on their perceptions of recent experiences and primary causes of incivility in higher education. Clark’s ( 2007, revised 2020) Conceptual Model for Fostering Civility in Nursing Education and Daniel Goleman’s (...) ( 1995 ) Emotional Intelligence domains were used to give meaning and context to the study findings. For this group of respondents, the study found that incivility in higher education between faculty, students, and faculty and student relationships remain pervasive. Despite the global pandemic and social unrest occurring during the study period, these behaviors did not coalesce around a specific subgroup. Both faculty and students agreed that relationship management with a keen focus on communication could mitigate academic incivility. These findings can inform educators, students, and future researchers in planning meaningful interventions that address incivility in higher education. A relational approach centered on communication skill-building is needed to combat the persistent issue of incivility in higher education. (shrink)

The study of ethical leadership has emerged as an important topic for understanding the effects of leadership in organizations. In a study with 845 working adults across multiple organizations, the relationships between ethical leadership with positive employee outcomes were examined. Results suggest that ethical leadership is related to both psychological well-being and job satisfaction in employees, but the processes are different. Employee voice mediated the relationship between ethical leadership and psychological well-being. Feelings of psychological ownership mediated the relationship between ethical (...) leadership and job satisfaction. A discussion of theoretical and practical implications concludes the article.

If we are to ensure the persistence of species in an increasingly warm world, of interest is the identification of drivers that affect the ability of an organism to resist thermal stress. Underpinning any organism's capacity for resistance is a complex interplay between biological and physical factors occurring over multiple scales. Tropical coral reefs are a unique system, in that their function is dependent upon the maintenance of a coral–algal symbiosis that is directly disrupted by increases in water temperature. A (...) number of physical factors have been identified as affecting the biological responses of the coral organism under broadscale thermal anomalies. One such factor is water flow, which is capable of modulating both organismal metabolic functioning and thermal environments. Understanding the physiological and hydrodynamic drivers of organism response to thermal stress improves predictive capabilities and informs targeted management responses, thereby increasing the resilience of reefs into the future.

BackgroundAs a number of commentators have noted, SARS exposed the vulnerabilities of our health care systems and governance structures. Health care professionals (HCPs) and hospital systems that bore the brunt of the SARS outbreak continue to struggle with the aftermath of the crisis. Indeed, HCPs – both in clinical care and in public health – were severely tested by SARS. Unprecedented demands were placed on their skills and expertise, and their personal commitment to their profession was severely tried. Many were (...) exposed to serious risk of morbidity and mortality, as evidenced by the World Health Organization figures showing that approximately 30% of reported cases were among HCPs, some of whom died from the infection. Despite this challenge, professional codes of ethics are silent on the issue of duty to care during communicable disease outbreaks, thus providing no guidance on what is expected of HCPs or how they ought to approach their duty to care in the face of risk.DiscussionIn the aftermath of SARS and with the spectre of a pandemic avian influenza, it is imperative that we (re)consider the obligations of HCPs for patients with severe infectious diseases, particularly diseases that pose risks to those providing care. It is of pressing importance that organizations representing HCPs give clear indication of what standard of care is expected of their members in the event of a pandemic. In this paper, we address the issue of special obligations of HCPs during an infectious disease outbreak. We argue that there is a pressing need to clarify the rights and responsibilities of HCPs in the current context of pandemic flu preparedness, and that these rights and responsibilities ought to be codified in professional codes of ethics. Finally, we present a brief historical accounting of the treatment of the duty to care in professional health care codes of ethics.SummaryAn honest and critical examination of the role of HCPs during communicable disease outbreaks is needed in order to provide guidelines regarding professional rights and responsibilities, as well as ethical duties and obligations. With this paper, we hope to open the social dialogue and advance the public debate on this increasingly urgent issue. (shrink)

The Mathematical Intelligencer recently published a note by Y. Sergeyev that challenges both mathematics and intelligence. We examine Sergeyev’s claims concerning his purported Infinity computer. We compare his grossone system with the classical Levi-Civita fields and with the hyperreal framework of A.

We show that Sergeyev’s grossone system is unnecessary and vague, and that whatever consistent subsystem could be salvaged is subsumed entirely within a stronger and (...) clearer system. Lou Kauffman, who published an article on a grossone, places it squarely outside the historical panorama of ideas dealing with infinity and infinitesimals. (shrink)

The study used a thematic analysis to examine student and faculty responses to two qualitative questions focused on their perceptions of the consequence of incivility and solutions that would embed civility expectations as a key element to professional role socialization in higher education. Participants included students and faculty across multiple academic programs and respondent subgroups at a regional university in the southern United States. A new adapted conceptual model using Clark’s in _Nursing Education Perspectives_, _28_(2), 93–97 ( 2007, revised 2020) (...) Conceptual Model for Fostering Civility in Nursing Education and Daniel Goleman’s in _Emotional intelligence: Why it can matter more than IQ_. Bantam Books ( 1995 ) Emotional Intelligence domains was used as the framework for this study to give meaning and context to its findings.

Leadership in higher education will strengthen their institutions by using a relational approach centered on communication skill-building to ensure that faculty have been socialized to the importance of civil professional behavior and that stakeholders collectively explore and agree on the meaning and organizational integration of civility.

ABSTRACT:Clinical ethics consultants bear witness to the direct harms of intersecting axes of oppression—such as racism and classism—as they impinge on elucidating and resolving ethical dilemmas in health care. Health Care Ethics Consultation (HCEC) professional guidance supports recognizing and analyzing power dynamics and social-structural obstacles to good care. However, the most relied upon bioethical principles in clinical ethics have been criticized for insufficiency in this regard. While individual ethics consultants have found ways to expand their approaches, they do so in (...) an ad hoc way without frameworks to guide consistency. Motivated by the practical expertise of clinical ethicists, this essay offers a new framework to support openness to analyzing power imbalances and respecting marginalized voices and values. This framework is grounded in transformative justice, where the aim is to take responsibility for oppression by centering and responding to moral perspectives and value systems that are all too often silenced.

From computerized medical records to databases of pharmacological interactions and automated provisional EKG readings, the emergence of information technology has significantly altered the practice of medicine. Information technology has been widely used to enhance diagnosis and treatment and to improve communication between providers. The advent of the Internet also brings far-reaching implications for patient–physician communication, challenging physicians, patients, and policymakers to consider its impact on the delivery of medical care and the therapeutic relationship. A new set of practices by patients (...) and physicians is unfolding in cyberspace, ranging from the use of e-mail to communicate between physicians and patients in an existing relationship to one-to-one consultations with an anonymous physician and ongoing online treatment, such as psychotherapy. These practices are emerging in both the for-profit and not-for-profit spheres. (shrink)

In this case report, we describe a woman with advancing dementia who still retained decisional capacity and was able to clearly articulate her request for deactivation of her implanted cardiac pacemaker—a scenario that would result in her death. In this case, the patient had the autonomy to make her decision, but clinicians at an outside hospital refused to deactivate her pacemaker even though they were in unanimous agreement that the patient had capacity to make this decision, citing personal discomfort and (...) a belief that her decision seemed out of proportion to her suffering. We evaluated her at our hospital, found her to have decision-making capacity, and deactivated her pacer resulting in her death about 9 days later. While some clinicians may be comfortable discussing patient preferences for device deactivation in patients who are imminently dying, we can find no reports in the literature of requests for device deactivation from patients with terminal diagnoses who are not imminently dying.

Despite the frequency of stillbirths, the subsequent implications are overlooked and underappreciated. We present findings from comprehensive, systematic literature reviews, and new analyses of published and unpublished data, to establish the effect of stillbirth on parents, families, health-care providers, and societies worldwide. Data for direct costs of this event are sparse but suggest that a stillbirth needs more resources than a livebirth, both in the perinatal period and in additional surveillance during subsequent pregnancies. Indirect and intangible costs of stillbirth are (...) extensive and are usually met by families alone. This issue is particularly onerous for those with few resources. Negative effects, particularly on parental mental health, might be moderated by empathic attitudes of care providers and tailored interventions. The value of the baby, as well as the associated costs for parents, families, care providers, communities, and society, should be considered to prevent stillbirths and reduce associated morbidity.

We advance a model of human probability judgment and apply it to the design of an extrapolation algorithm. Such an algorithm examines a person's judgment about the likelihood of various statements and is then able to predict the same person's judgments about new statements. The algorithm is tested against judgments produced by thirty undergraduates asked to assign probabilities to statements about mammals.

On November 8, 1994, Oregon became the first state in the nation to legalize assisted suicide. Passage of Proposition 16 was a milestone in the campaign to make assisted suicide a legal option. The culmination of years of effort, the Oregon vote followed on the heels of failed referenda in California and Washington, and other unsuccessful attempts to enact state laws guaranteeing the right to suicide assistance. Indeed, in 1993, four states passed laws strengthening or clarifying their ban against assisted (...) suicide. No doubt, Proposition 16 is likely to renew the effort to legalize assisted suicide at the state level.The battle over assisted suicide is also unfolding in the courts. Litigation challenging Proposition 16 on the grounds that it violates the equal protection clause is ongoing in Oregon. More significantly, three cases, two in federal courts and one in Michigan state court, have been brought to establish assisted suicide as a constitutionally protected right. (shrink)
