Histories of artists' personal possessions shed new light
on the lives of their owners. Artists are makers of
things. Yet it is a measure of the disembodied manner in which we
generally think about ...artists that we rarely consider the everyday
items they own. This innovative book looks at objects that once
belonged to artists, revealing not only the fabric of the
eighteenth-century art world in France but also unfamiliar-and
sometimes unexpected-insights into the individuals who populated
it, including Jean-Antoine Watteau, François Boucher, Jean-Baptiste
Greuze, and Elisabeth Vigée-LeBrun. From the curious to the
mundane, from the useful to the symbolic, these items have one
thing in common: they have all been eclipsed from historical view.
Some of the objects still exist, like Jean-Honoré Fragonard's color
box and Jacques-Louis David's table. Others survive only in
paintings, such as Jean-Siméon Chardin's cistern in his Copper
Drinking Fountain , or in documents, like François Lemoyne's
sword, the instrument of his suicide. Several were literally lost,
including pastelist Jean-Baptiste Perronneau's pencil case. In this
fascinating book, the authors engage with fundamental historical
debates about production, consumption, and sociability through the
lens of material goods owned by artists. The free online edition of
this open-access publication is at
www.getty.edu/publications/artists-things/ and includes zoomable
illustrations. Free PDF and EPUB downloads of the book are also
available.
Despite the interest in MXenes in the past decade, MXenes are often highly disordered, which can complicate their study and use. For example, nearly all MXenes have a random mixture of surface ...terminations (−O, −OH, −F). In addition, restacked 3D films have turbostratic disorder and often contain ions, solvent, and other species in between their layers. Here, we report Y2CF2, a layered crystal with a unit cell isostructural to a MXene, in which layers are capped only by fluoride anions. We directly synthesize the 3D crystal through a high-temperature solid-state reaction, which affords the 3D crystal in high yield and purity and ensures that only fluoride ions terminate the layers. We characterize the crystal structure and electronic properties using a combination of experimental and computational techniques. We find that relatively strong electrostatic interactions bind the layers together into a 3D crystal and further find that the lack of orbital overlap between layers gives rise to a description of Y2CF2 as slabs of MXene-like sheets electrically insulated from one another. Therefore, we consider Y2CF2 as a pure 3D crystalline stack of MXene-like sheets. In addition, Y2CF2 is the first transition metal carbide fluoride experimentally synthesized. We hope this work inspires further exploration of transition metal carbide fluorides, which are potentially a large and useful class of compositions.
In mammals, hair cells and spiral ganglion neurons (SGNs) in the cochlea together are sophisticated “sensorineural” structures that transduce auditory information from the outside world into the ...brain. Hair cells and SGNs are joined by glutamatergic ribbon‐type synapses composed of a molecular machinery rivaling in complexity the mechanoelectric transduction components found at the apical side of the hair cell. The cochlear hair cell ribbon synapse has received much attention lately because of recent and important findings related to its damage (sometimes termed “synaptopathy”) as a result of noise overexposure. During development, ribbon synapses between type I SGNs and inner hair cells form in the time window between birth and hearing onset and is a process coordinated with type I SGN myelination, spontaneous activity, synaptic pruning, and innervation by efferents. In this review, we highlight new findings regarding the diversity of type I SGNs and inner hair cell synapses, and the molecular mechanisms of selective hair cell targeting. Also discussed are cell adhesion molecules and protein constituents of the ribbon synapse, and how these factors participate in ribbon synapse formation. We also note interesting new insights into the morphological development of type II SGNs, and the potential for cochlear macrophages as important players in protecting SGNs. We also address recent studies demonstrating that the structural and physiological profiles of the type I SGNs do not reach full maturity until weeks after hearing onset, suggesting a protracted development that is likely modulated by activity.
Ribbon synapses between inner hair cells and type I spiral ganglion neurons (SGNs) represent the first synaptic junction in the auditory pathway. We report here on recent insights into the cellular and molecular mechanisms controlling selective hair cell targeting, adhesion between SGNs and hair cells, and SGN differentiation.
A direct intermolecular decarboxylative Giese amidation reaction from bench stable, non-toxic and environmentally benign oxamic acids has been developed, which allows for easy access to ...1,4-difunctionalised compounds which are not otherwise readily accessible. Crucially, a more general acceptor substrate scope is now possible, which renders the Giese amidation applicable to more complex substrates such as natural products and chiral building blocks. Two different photocatalytic methods (one
via
oxidative and the other
via
reductive quenching cycles) and one metal- and light-free method were developed and the flexibility provided by different conditions proved to be crucial for enabling a more general substrate scope.
This essay draws upon Donovan's conceptualization of "communication as work" to explicate types of communicative work undertaken by the authors - two patients with vulvodynia, a poorly understood ...chronic genital pain condition - during patient-provider interactions prior to diagnosis. Uniquely positioned as patients-turned-scholars, we extend the rich construct of "communication work" by narrating the types of communicative work undertaken ourselves as patients communicating within a stigmatized health context for which a clear diagnosis is often ambiguous or unable to be reached. Donovan notes that conditions with a high degree of uncertainty and ambiguity have the capacity to shift the nature of talk. This brief essay illustrates the ways in which the nature of patient-provider communication work is shifted by the ambiguity of this health context. Theoretical and practical implications are briefly offered.
Chronic pelvic and genital pain conditions (CPGPCs) often go undiagnosed and untreated in women for years after symptom onset. This is due, in part, to communication challenges experienced by ...patients such as difficulties describing pain and the stigmatized nature of CPGPCs. However, studies have yet to explore how early messages about menstruation, a context similar in its stigmatized and painful nature, may contribute to undertreatment and diagnostic delays for adult women experiencing CPGPCs by normalizing pelvic and genital pain when they are young girls. Guided by critical feminist theorizing (CFT) and sensitized by an existing typology of negative messages communicated by mothers to daughters about menstruation, this study analyzes interviews with 17 women with CPGPCs to explore how features of negative messages about menstruation (i.e., information restriction and omission) appear and recur in women's descriptions of their later CPGP experiences. Findings suggest that early life talk about menstruation forms a communicative precedent for young girls which later constrains how they talk about CPGP in adulthood. Findings also problematize early-life communication about menstruation, which normalizes women's pain, and suggest connections to outcomes (e.g., diagnostic delays) for women with CPGPCs. Theoretical and practical implications are offered. Limitations and future directions are described.
In Lilian Cibils dissertation-turned-book, Immigration, Motherhood and Parental Involvement: Narratives of Communal Agency in the Face of Power Asymmetry (2017), the stories of seven Mexican ...immigrant mothers provide insight into what motherhood looks like outside the mainstream ideology of parental involvement. Using a critical feminist lens, Cibils employs the concept of motherwork as an alternative to a cultural deficit approach for understanding Mexican immigrant motherhood.
Abstract
Introduction
The Covid-19 pandemic, which affected medical students globally, could be viewed as a disorientating dilemma with the potential to offer opportunities for transformative ...learning. In 2021 the Medical Education Innovation and Research Centre at Imperial College London launched a Global Creative Competition as a platform for medical students to reflect on their experiences during the pandemic.
Methods
Six hundred forty-eight creative pieces with written reflections were submitted by medical students from 52 countries. 155 students from 28 countries consented for their entries to be included in this study. The reflections were analysed thematically and independently by three reviewers to explore how the pandemic impacted students’ professional identity formation (PIF).
Results
The pandemic increased students’ awareness of the social and global role of doctors in addressing health inequities. Students felt part of a wider healthcare community and showed greater appreciation towards person-centred care. Students also became more aware of their personal needs, priorities, and the importance of self-care.
Discussion
In agreement with Mezirow’s theory of transformative learning (2003), the pandemic led students to re-examine pre-existing epistemic and sociocultural assumptions concerning the role of doctors and explore new perspectives of what it means to be a doctor. In accordance with Cheng’s theory of coping flexibility (2021), students developed both emotion-focused coping strategies (e.g., arts engagement) and problem-solving strategies (e.g., volunteering), suggesting they were able to adjust psychologically and develop agency. However, students experienced tension between their sense of duty and sense of wellbeing, highlighting the need for medical educators to design into programmes formal support systems where medical students have the space and time they need to reflect on their emergent identities as a doctor.
Conclusion
Medical educators should encourage students to reflect on their identity formation while encountering disorientating dilemmas. The inclusion of arts and humanities within the medical curriculum is strongly recommended to provide an avenue for students to access and express complex emotions and experiences.
Sport-related concussions (SRCs) affect millions of adolescents and young adults annually in the USA; however, current SRC consensus statements provide limited guidance on academic support for ...students within higher education.
To generate consensus on appropriate academic recommendations for clinicians, students, and academic stakeholders to support university students during their recovery.
Panelists participated in three stages of a modified Delphi procedure: the first stage included a series of open-ended questions after reviewing a literature review on post-SRC return-to-learn (RTL) in higher education; the second stage asked panelists to anonymously rate the recommendations developed through the first Delphi stage using a 9-point scale; and the final stage offered panelists the opportunity to change their responses and/or provide feedback based on the group's overall ratings.
Twenty-two panelists including clinicians, concussion researchers, and academic stakeholders (54.5% female) from 15 institutions and/or healthcare systems participated in a modified Delphi procedure. A total of 42 statements were developed after round one. Following the next two rounds, 27 statements achieved consensus amongst the panel resulting in the four-stage Post-Concussion Collegiate RTL Protocol.
There are several unique challenges when assisting university students back to the classroom after SRC. Explicit guidelines on when to seek additional medical care (e.g., if they are experiencing worsening or persistent symptoms) and how to approach their instructor(s) regarding academic support may help the student self-advocate. Findings from the present study address barriers and provide a framework for universities to facilitate a multidisciplinary approach amongst medical and academic stakeholders.
A growing number of endurance athletes have considered switching from a traditional high-carbohydrate/low-fat (HCLF) to a low-carbohydrate/high-fat (LCHF) eating pattern for health and performance ...reasons. However, few studies have examined how LCHF diets affect blood lipid profiles in highly-trained runners. In a randomized and counterbalanced, cross-over design, athletes (n = 7 men; VO2max: 61.9 ± 6.1 mL/kg/min) completed six weeks of two, ad libitum, LCHF (6/69/25% en carbohydrate/fat/protein) and HCLF (57/28/15% en carbohydrate/fat/protein) diets, separated by a two-week washout. Plasma was collected on days 4, 14, 28, and 42 during each condition and analyzed for: triglycerides (TG), LDL-C, HDL-C, total cholesterol (TC), VLDL, fasting glucose, and glycated hemoglobin (HbA1c). Capillary blood beta-hydroxybutyrate (BHB) was monitored during LCHF as a measure of ketosis. LCHF lowered plasma TG, VLDL, and TG/HDL-C (all p < 0.01). LCHF increased plasma TC, LDL-C, HDL-C, and TC/HDL-C (all p < 0.05). Plasma glucose and HbA1c were unaffected. Capillary BHB was modestly elevated throughout the LCHF condition (0.5 ± 0.05 mmol/L). Healthy, well-trained, normocholesterolemic runners consuming a LCHF diet demonstrated elevated circulating LDL-C and HDL-C concentrations, while concomitantly decreasing TG, VLDL, and TG/HDL-C ratio. The underlying mechanisms and implications of these adaptive responses in cholesterol should be explored.
