The establishment of language as a focus of study took place over many centuries, and reflection on its nature emerged in relation to very different social and cultural practices. Written by a team of leading scholars, this volume provides an authoritative, chronological account of the history of the study of language from ancient times to the end of the 20th century (i.e., 'recent history', when modern linguistics greatly expanded). Comprised of 29 chapters, it is split into 3 parts, each with an introduction covering the larger context of interest in language, especially the different philosophical, religious, and/or political concerns and socio-cultural practices of the times. At the end of the volume, there is a combined list of all references cited and a comprehensive index of topics, languages, major figures, etc. Comprehensive in its scope, it is an essential reference for researchers, teachers and students alike in linguistics and related disciplines.
Burnout is a major psychological and physical health-related problem for workers in all fields, but especially for those in the fast-paced and rapidly changing world of healthcare. Burnout has severe consequences for patients, including medical error, and is a leading contributing cause of depression and suicide among healthcare workers. Organizational science is just beginning to be applied in earnest to physician burnout and patient safety, and holds several potential keys to addressing these concerns. The Burned Out Physician is for two groups: healthcare workers (especially physicians) and patients. Physicians will use this book to get an accurate picture of what they are experiencing and how to change it, and patients will use this book to see what their healthcare providers are experiencing and learn how to help and/or protect themselves. The volume includes a checklist of burnout symptoms, and crucially a list of solutions as part of an active effort to solve the burnout crisis.
Trichotillomania (TTM) and skin picking disorder (SPD) are common and often debilitating mental health conditions, grouped under the umbrella term of body-focused repetitive behaviors (BFRBs). Recent clinical subtyping found that there were three distinct subtypes of TTM and two of SPD. Whether these clinical subtypes map on to any unique neurobiological underpinnings, however, remains unknown.
Methods
Two hundred and fifty one adults [193 with a BFRB (85.5% [n = 165] female) and 58 healthy controls (77.6% [n = 45] female)] were recruited from the community for a multicenter between-group comparison using structural neuroimaging. Differences in whole brain structure were compared across the subtypes of BFRBs, controlling for age, sex, scanning site, and intracranial volume.
Results
When the subtypes of TTM were compared, low awareness hair pullers demonstrated increased cortical volume in the lateral occipital lobe relative to controls and sensory sensitive pullers. In addition, impulsive/perfectionist hair pullers showed relative decreased volume near the lingual gyrus of the inferior occipital–parietal lobe compared with controls.
Conclusions
These data indicate that the anatomical substrates of particular forms of BFRBs are dissociable, which may have implications for understanding clinical presentations and treatment response.
In the context of English and Spanish in contact, issues of identity arise at various levels, including: how people’s national and ethnic identities are bound up with their language choices; how the national and ethnic identities were formed historically, and are continually re-formed, in conjunction with languages; how languages themselves are defined – how the English and Spanish (or Castilian) languages came to be recognised as such, and likewise for Scots or Galician or Catalan as languages apart, where many other varieties are regarded as dialects; how contact between English and Spanish, which principally means their knowledge and use by bilinguals, affects these conceptions of languages and national and ethnic identities. This chapter examines these issues in terms not just of Spanish and English, but of Spanishes and Englishes in their global diversity, together with the other languages with which they share multilingual spaces. A wide range of recent studies on bilingual identities are taken into consideration, as is current work on the effects of globalisation, superdiversity and translanguaging.
Quasi-periodic plasmoid formation at the tip of magnetic streamer structures is observed to occur in experiments on the Big Red Ball as well as in simulations of these experiments performed with the extended magnetohydrodynamics code, NIMROD. This plasmoid formation is found to occur on a characteristic time scale dependent on pressure gradients and magnetic curvature in both experiment and simulation. Single mode, or laminar, plasmoids exist when the pressure gradient is modest, but give way to turbulent plasmoid ejection when the system drive is higher, which produces plasmoids of many sizes. However, a critical pressure gradient is also observed, below which plasmoids are never formed. A simple heuristic model of this plasmoid formation process is presented and suggested to be a consequence of a dynamic loss of equilibrium in the high-$\beta$ region of the helmet streamer. This model is capable of explaining the periodicity of plasmoids observed in the experiment and simulations, and produces plasmoid periods of 90 minutes when applied to two-dimensional models of solar streamers with a height of $3R_\odot$. This is consistent with the location and frequency at which periodic plasma blobs have been observed to form by Large Angle and Spectrometric Coronograph and Sun Earth Connection Coronal and Heliospheric Investigation instruments.
Magnetic reconnection is explored on the Terrestrial Reconnection Experiment (TREX) for asymmetric inflow conditions and in a configuration where the absolute rate of reconnection is set by an external drive. Magnetic pileup enhances the upstream magnetic field of the high-density inflow, leading to an increased upstream Alfvén speed and helping to lower the normalized reconnection rate to values expected from theoretical consideration. In addition, a shock interface between the far upstream supersonic plasma inflow and the region of magnetic flux pileup is observed, important to the overall force balance of the system, thereby demonstrating the role of shock formation for configurations including a supersonically driven inflow. Despite the specialized geometry where a strong reconnection drive is applied from only one side of the reconnection layer, previous numerical and theoretical results remain robust and are shown to accurately predict the normalized rate of reconnection for the range of system sizes considered. This experimental rate of reconnection is dependent on system size, reaching values as high as 0.8 at the smallest normalized system size applied.
Implementation of clinically useful research discoveries in the academic environment is challenged by limited funding for early phase proof-of-concept studies and inadequate expertise in product development and commercialization. To address these limitations, the National Institutes of Health (NIH) established the National Centers for Accelerated Innovations (NCAI) program in 2013. Three centers competed successfully for awards through this mechanism. Here, we present the experience of one such center, the Boston Biomedical Innovation Center (B-BIC), and demonstrate its remarkable success at the translation of innovations to clinical application and commercialization, as well as skills development and education.
Previous genetic association studies have failed to identify loci robustly associated with sepsis, and there have been no published genetic association studies or polygenic risk score analyses of patients with septic shock, despite evidence suggesting genetic factors may be involved. We systematically collected genotype and clinical outcome data in the context of a randomized controlled trial from patients with septic shock to enrich the presence of disease-associated genetic variants. We performed genomewide association studies of susceptibility and mortality in septic shock using 493 patients with septic shock and 2442 population controls, and polygenic risk score analysis to assess genetic overlap between septic shock risk/mortality with clinically relevant traits. One variant, rs9489328, located in AL589740.1 noncoding RNA, was significantly associated with septic shock (p = 1.05 × 10–10); however, it is likely a false-positive. We were unable to replicate variants previously reported to be associated (p < 1.00 × 10–6 in previous scans) with susceptibility to and mortality from sepsis. Polygenic risk scores for hematocrit and granulocyte count were negatively associated with 28-day mortality (p = 3.04 × 10–3; p = 2.29 × 10–3), and scores for C-reactive protein levels were positively associated with susceptibility to septic shock (p = 1.44 × 10–3). Results suggest that common variants of large effect do not influence septic shock susceptibility, mortality and resolution; however, genetic predispositions to clinically relevant traits are significantly associated with increased susceptibility and mortality in septic individuals.
