Patients completed two social needs screening tools and responded to additional questions on housing. Housing status was determined using validated questions about housing stability.\nResults: Of the 1,263 eligible patients, 758 (60.0%) completed the survey. Among respondents, 40% identified as Latinx, 39% Black, 15% White, 5% Asian, and 8% other race/ethnicities. The median age was 42 years (interquartile range [IQR]: 29-57). and 54% were male. Of the 758 patients who completed the survey, 281 (37.1%) were housed, 213 (28.1%) were unstably housed, and 264 (34.8%) were homeless. A disproportionate number of patients experiencing homelessness were male (63.3%) and Black (54.2%), P <0.001, and a disproportionate number of unstably housed patients were Latinx (56.8%) or were primarily Spanish speaking (49.3%), P <0.001. Social needs increased across the spectrum of housing from housed to unstably housed and homeless, even when controlling for demographic characteristics.\nConclusion: Over one in three ED patients experience homelessness, and nearly one in three are unstably housed. Notable disparities exist by housing status, and there is a clear increase of social needs across the housing spectrum. Emergency departments should consider integrating social screening tools for patients with unstable housing.", "language": "en", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

The patient was hemodynamically unstable and in respiratory distress. Computed tomography revealed a massive hemothorax on the left side and compression of the descending thoracic aorta. He underwent emergency surgical exploration after decompression by chest tube insertion. The hemothorax was caused by tears in the pleural adhesions due to asbestosis and induced by coughing.\nDiscussion:\n Spontaneous hemothorax is a rare subtype of hemothorax. There have been only a few case reports of spontaneous tension hemothorax. In addition to its typical findings, compression of the thoracic descending aorta was observed in our patient.

A radiograph of the right knee revealed a tibial spine fracture.\nDiscussion: \nTibial spine fractures are avulsion fractures of the spine of the tibia at the insertion site of the anterior cruciate ligament. The incidence of avulsion fractures is higher in adolescents because the region of the apophyseal growth plate between the soft-tissue attachment site and the body of the bone is weaker in that age group. Tibial spine avulsion fractures are relatively uncommon and occur annually in approximately three per 100,000 children.", "language": "en", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

As a human-medical borderline experience, it was a scientific driving force, a political destabilizing factor, and a challenge to poetics. At the interface of literary studies and medical history and by using nineteenth-century literary texts from North American, British, and German authors as examples, this transnational study shows for the first time comprehensively, that despite a supposed “impossibility of narration”, the traumatic pandemic experience of cholera found its way into contemporary literature, particularly in the model of the specter. Through culturally and historically framed textual analyses of literary texts by Edgar Allan Poe, Mark Twain, George Eliot, H.G. Wells, Heinrich Heine, Ricarda Huch, and others as well as a variety of contemporary life writing documents, the study explores the multifarious intersections of lifeworld and literature. Within the methodological and theoretical framework of the Medical Humanities and Gothic Studies, it thus reveals genuine strategies for making the unspeakable speakable. By the use of epi- and pandemic experience as an example of a state of emergency, the study shows how closely scientific, political, social, and cultural discourses are interwoven, how they influence each other, and what role art and literature play in these processes of exchange. \n The Spectre of the Pandemic\n thus raises awareness of the interdependence of most diverse knowledge formations and is a plea for inter- and transdisciplinary thinking and research, especially in times of crisis.

In Experiment 2, on possessor pronouns, we found that this preference was much weaker. We conclude that when a morphological distinction between reflexive anaphors and pronominals is absent, comprehenders do prefer to assign reflexive interpretations.

a prominent component of multimodal pain management in emergency medicine (EM), and its use has increased rapidly in recent decades. Nevertheless, there is a paucity of data on how RA practice has evolved in the specialty. In this study we sought to investigate how RA has been implemented in EM by analyzing trends of published articles and to describe the characteristics of the published research.\n \nMethods:\n We retrieved RA-related publications from the SciVerse Scopus database from inception to January 13, 2022, focusing on studies associated with the use of RA in EM. The primary outcome was an analysis of trend based on the number of annual publications. Other outcomes included reports of technique diversity by year, trends in the use of individual techniques, and characteristics of published articles. We used linear regression analysis to analyze trends.\n \nResults:\n In total, 133 eligible publications were included. We found that overall 23 techniques have been described and results published in the EM literature. Articles related to RA increased from one article in 1982 to 18 in 2021, and the rate of publication has increased more rapidly since 2016. Reports of lower extremity blocks (60.90%) were published most frequently in ranked-first aggregated citations. The use of thoracic nerve blocks, such as the erector spinae plane block, has increased exponentially in the past three years. The United States (41.35%) has published the most RA-related articles. Regional anesthesia administered by emergency physicians (52.63%) comprised the leading field in published articles related to RA. Most publications discussed single-shot (88.72%) and ultrasound-guided methods (55.64%).\n \nConclusion: \nThis study highlights that the number of published articles related to regional anesthesia in EM has increased. Although RA research has primarily focused on lower extremity blocks, clinical researchers continue to broaden the field of study to encompass a wide spectrum of techniques and indications.", "language": "en", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

A Review of the Clinical Value of Oblique Knee Radiographs in the Acute Setting", "subtitle": null, "abstract": "Introduction:\n The purpose of this study was to assess the added clinical value of oblique knee radiographs four-view (4V) compared to orthogonal anteroposterior (AP) and lateral radiographs in a two-view (2V) series.\nMethods: \nWe obtained 200 adult, 4V knee radiographs in 200 patients in the ED and randomly divided them into two groups with 100 series in each group. Ten reviewers — three musculoskeletal radiologists and seven orthopedic surgeons — performed radiograph analyses. These reviewers were randomly divided evenly into group one and group two. Reviewers were blinded to patient data and first reviewed 2V radiographs (AP/lateral) only, and then reviewed 4V radiographs, including AP/lateral, and two additional oblique views for the same patients at least four weeks later. Acute pathology identification and the need for further imaging was assessed for all reviewers, and clinical decision-making (operative vs nonoperative treatment, need for admission, need for additional imaging) was assessed only by the seven orthopaedic surgeon reviewers. \nResults:\n Mean sensitivity for pathology identification was 79% with 2V and 81% with 4V (P =0.25). Intra-observer kappa value was 0.81 (range 0.54-1.00). Additional oblique radiographs led orthopaedic reviewers to change their treatment recommendations in 62/329 patients (18.84%) (P <0.001). Eight of 329 radiographic series were identified as “critical misses.” (2.43%) (P =0.004), when pathology was reported as normal or reviewers recommended nonoperative treatment on 2V radiographs but changed their recommendation to operative management after the addition of oblique radiographs. The number needed to treat (NNT) for any treatment change and for “critical misses” was 83 and 643, respectively. \nConclusion:\n Although the addition of oblique radiographs may improve a clinician’s ability to identify subtle pathologic findings not identified on 2V, it rarely leads to significant changes in treatment recommendations. Given the high NNT, limiting the usage of these oblique radiographs in the general patient population may reduce costs without significantly affecting patient care.", "language": "en", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

In this study we evaluated the association between patients’ self-identified race/ethnicity and the administration of opioid analgesia among ED patients with abdominal pain, the most common chief complaint for ED presentations in the United States.\n \nMethods: \nThis was a retrospective cohort study of adult (age ≥18 years) patients who presented to the ED of a single center with abdominal pain from January 1, 2019–December 31, 2020. We collected demographic and clinical information, including patients’ race and ethnicity, from the electronic health record. The primary outcome was the ED administration of any opioid analgesic (binary). Secondary outcomes included the administration of non-opioid analgesia (binary) and administration of any analgesia (binary). We used logistic regression models to estimate odds ratios (OR) of the association between a patient’s race/ethnicity and analgesia administration. Covariates included age, sex, initial pain score, Emergency Severity Index, and ED visits in the prior 30 days. Subgroup analyses were performed in non-pregnant patients, those who underwent any imaging study, were admitted to the hospital, and who underwent surgery within 24 hours of ED arrival.\nResults:\n We studied 7,367 patients: 45% (3,314) were non-Hispanic (NH) White; 28% (2,092) were Hispanic/Latinx; 19% (1,384) were NH Black, and 8% (577) were Asian. Overall, 44% (3,207) of patients received opioid analgesia. In multivariable regression models, non-White patients were less likely to receive opioid analgesia compared with White patients (OR 0.73, 95% CI 0.65-0.83 for Hispanic/Latinx patients; OR 0.62, 95% CI 0.54-0.72 for Black patients; and OR 0.64, 95% CI 0.52-0.78 for Asian patients). Black patients were also less likely to receive non-opioid analgesia, and Black and Hispanic/Latinx patients were less likely than White patients to receive any analgesia. The associations were similar across subgroups; however, the association was attenuated among patients who underwent surgery within 24 hours of ED arrival. \nConclusion:\n Hispanic/Latinx, Black, and Asian patients were significantly less likely to receive opioid analgesia than White patients when presenting to the ED with abdominal pain.

Ultrasound is the imaging tool of choice, but its use is complicated due to anatomical changes during pregnancy and depends on the clinician’s expertise. In this study, our aim was to investigate the diagnostic accuracy of point-of-care ultrasound (POCUS) in suspected appendicitis in pregnant women.\nMethods: \nWe conducted a retrospective analysis of all pregnant women undergoing POCUS for suspected appendicitis between June 2010–June 2020 in a tertiary emergency department. The primary outcome was to establish sensitivity, specificity, and likelihood ratios of POCUS in diagnosing acute appendicitis, overall and for each trimester. We used histology of the appendix as the reference standard in case of surgery. If appendectomy was not performed, the clinical course until childbirth was used to rule out appendicitis. If the patients underwent magnetic resonance imaging (MRI), we compared readings to POCUS.\nResults:\n A total of 61 women were included in the study, of whom 34 (55.7%) underwent appendectomy and in 30 (49.2%) an acute appendicitis was histopathologically confirmed. Sensitivity of POCUS was 66.7% (confidence interval [CI] 95% 47.1-82.7), specificity 96.8% (CI 95% 83.3-99.9), and positive likelihood ratio 20.7. Performance of POCUS was comparable in all trimesters, with highest sensitivity in the first trimester (72.7%). The MRI reading showed a sensitivity of 84.6% and a specificity of 100%. In the four negative appendectomies a MRI was not performed.\nConclusion:\n Point-of-care ultrasound showed a high specificity and positive likelihood ratio in diagnosing acute appendicitis in pregnant women in all trimesters with suspected appendicitis.

The purpose of this study was to evaluate the potential role of FMA in the acute care of patients with frostbite, specifically its role as a tool to identify perfusion deficit following severe frostbite injury, and to explore its role in time to tissue plasminogen activator (tPA).\nMethods:\n This retrospective analysis included all patients from December 2020–March 2021 who received FMA in a single ED as part of their initial frostbite evaluation. In total, 42 patients presented to the ED with concern for frostbite and were evaluated using FMA.\nResults:\n Mean time from arrival in the ED to FMA was 46.3 minutes. Of the 42 patients, 14 had clinically significant perfusion deficits noted on FMA and received tPA. Mean time to tPA (measured from ED arrival to administration of tPA) for these patients was 117.4 minutes. This is significantly faster than average historical times at our institution of 240-300 minutes.\nConclusion:\n Bedside FMA provides objective information regarding perfusion deficits and allows for faster decision-making and improved times to tPA. Fluorescence microangiography shows promise for quick and efficient evaluation of perfusion deficits in frostbite-injured patients. This could lead to faster tPA administration and potentially greater rates of tissue salvage after severe frostbite injury.", "language": "en", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

Complication rates depend on the procedure type, gestational age, patient comorbidities, clinician experience, and most importantly, whether the abortion is safe or unsafe. Safe abortions have significantly lower complication rates compared to unsafe abortions. Complications include bleeding, retained products of conception, retained cervical dilator, uterine perforation, amniotic fluid embolism, misoprostol toxicity, and endometritis.

This has inspired research within the SFE at the southern edge of their distribution. However, populations also exist in other estuaries along the coast, which are far less described despite their potential importance in a metapopulation. We surveyed Longfin Smelt populations along the northern California coast for larval recruitment. We conducted surveys in 2019 and 2020 to (1) identify estuaries north of SFE where spawning occurs, and (2) evaluate how habitat features (e.g., salinity, temperature, dissolved oxygen, turbidity) influenced Longfin Smelt larvae abundance. We detected larvae in four of 16 estuaries we surveyed, and all were large estuaries north of Cape Mendocino. No larvae were detected in eight coastal estuaries in closer proximity to the SFE. Larvae catch probability increased with turbidity and decreased with salinity with no significant influence of temperature and dissolved oxygen. In the wet winter of 2019, we observed lower densities of larvae in Humboldt Bay and the Eel River and detected no Longfin Smelt in the Klamath and Mad Rivers, while in the dry winter of 2020, we detected larvae in two additional estuaries. Elevated freshwater outflow in 2019 possibly increased transport rates to sea, resulting in observed low larval recruitment. Our results sugget that, although populations of Longfin Smelt exist in large estuaries north of Cape Mendocino, coastal estuaries in proximity to the SFE were either under sampled or are not permanently inhabited by Longfin Smelt. Longfin Smelt in the SFE may therefore lack resilience normally afforded by metapopulations. Increased monitoring over their coastal range under varying hydrologic conditions is needed to assess gene flow between populations.", "language": "en", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

I designed an approach to evaluate how reduced sampling would alter our ability to describe the status and trends of key species. This approach can evaluate the sensitivity of the estuary monitoring program to disruptions in sampling and whether sampling effort could be reduced without compromising the information provided by these surveys. I simulated reduced sampling on top of the historical data record (1985 – 2018) by selectively removing data and evaluating the impact on model inference. The same model structure is fit to the full dataset and several reduced datasets representing simulations of reduced sampling effort. Model predictions from reduced models are then compared to those from the full model to evaluate how reduced sampling may have affected our ability to detect key patterns in the data. In a case study, I applied this approach to Sacramento Splittail abundance trends from the Bay Study and the Suisun Marsh Fish Study otter trawls. Sampling reductions of 10 and 20% had fairly low impacts on the overlap of reduced model predictions with those from the full model. These results demonstrate the utility of my approach, but they are not generalizable beyond our ability to detect trends in Splittail abundance from Bay Study and Suisun Marsh Fish Study otter trawl data. A thorough analysis should run these simulations on multiple species and multiple parameters (e.g., abundance, distribution, length). By simulating sampling reductions on top of historical conditions, this approach could evaluate differential impacts in varying environmental or historical conditions (e.g., droughts, species declines, invasions).

Loss of natural habitat and restoration actions reversing habitat loss can modify relationships between non-native predators and prey. Predicting how these relationships will change is often difficult because insufficient information exists on the habitat-specific feeding ecology of non-native predators. To address this information gap, we examined diets of non-native Striped Bass (\nMorone saxatilis\n; 63 to 671 mm standard length; estimated age 1-5 yrs) in the San Francisco Estuary during spring and summer in three habitat types – marsh, shoal, and channel – with the marsh habitat type serving as a model for ongoing and future restoration. Based on a prey-specific index of relative importance, Striped Bass diets were dominated by macroinvertebrates in spring and summer (amphipods in spring, decapods and isopods in summer). In spring, diets were relatively consistent across habitats. In summer, marsh diets were dominated by sphaeromatid isopods and shoal/channel diets by idoteid amphipods and decapods. Striped Bass consumed a variety of native and non-native fishes, primarily Prickly Sculpin (\nCottus asper\n) and Gobiidae. The highest importance of fish prey was in the marsh in spring (~40% prey weight), and fish prey comprised less than 25% prey weight in all other season/habitat combinations. Linear discriminant analyses suggested that marsh foraging was prevalent in Striped Bass collected in other habitats, mostly due to the predominance of marsh-associated invertebrates found in the stomachs of individual Striped Bass collected outside of the marsh. Striped Bass diets differ across habitats, with marsh foraging important to Striped Bass regardless of collection location.

To characterize the benefits of restoration sites, it is critical to quantify the abundance and composition of fish food resources in and near the wetlands. Characterization of zooplankton communities is considered particularly important, but accurate analysis of zooplankton samples is time-consuming and expensive. The recently established Fish Restoration Program (FRP) Monitoring Team assessed whether data from existing long-term monitoring surveys could be used to characterize shallow-water zooplankton communities prior to restoration. During the springs of 2017-2019, FRP collected zooplankton samples near the mouth of tidal wetland sites, or immediately outside future restoration sites, and compared them to concurrent samples collected in deep water by existing long-term monitoring surveys. We found very few differences in community composition between shallow and deep samples, though a few taxa were more abundant in shallow water. Seasonal and inter-annual differences in composition and abundance showed that restoration sites provide varying food resources over time. There was significantly higher total abundance of zooplankton in deep versus shallow water, which may be due to differences in zooplankton production, migration, or fish predation. There may also be inconsistencies in towing speed and gear type driving this result, rather than true habitat differences.

Wakasagi (Hypomesus nipponensis, referred to as Japanese Pond Smelt) are native to Japan and were once separated from their non-native congener the endangered Delta Smelt (Hypomesus transpacificus) of the San Francisco Estuary (hereon ‘estuary’) of California (CA). Wakasagi were introduced into CA reservoirs in the 20th century as forage fish. Wakasagi have since expanded their distribution downstream to the estuary, but less is known about Wakasagi’s current distribution status and biology in the estuary, and negative influences on Delta Smelt. In this study, we took a comparative approach by synthesizing long-term field monitoring surveys, modeling environmental associations, and quantifying phenology, growth, and diets of Wakasagi and Delta Smelt to describe abundance and range, trends of co-occurrence, and shared ecological roles between smelt species. We found Wakasagi in greatest abundance in the upper watershed below source reservoirs and in the northern regions of the estuary with the most co-occurrence with Delta Smelt; however, their range extends to western regions of the estuary, and we found evidence of an established population that annually spawns and rears in the estuary. We found these smelt species have similar ecological roles demonstrated by overlaps in habitat use (e.g., an association with higher turbidities and higher outflow), phenology, growth, and diets. Despite similarities, earlier hatching and rearing of Wakasagi during cooler months and reduced growth during warmer drought years suggest this species is unlike typical non-natives (e.g., Centrarchids), and they exhibit a similar sensitivity to environmental variability as Delta Smelt. This sensitivity may be why Wakasagi abundance remains relatively low in the estuary.", "language": "en", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

Patients who are discharged home must be both medically stable and able to safely isolate to prevent disease spread. Socioeconomically disadvantaged patient populations in particular may lack resources to safely quarantine and are at high risk for COVID-19 morbidity.\nMethods\nWe developed a telehealth follow-up program for emergency department (ED) patients who received testing for COVID-19 from April 24 to June 29, 2020 and were discharged home. Patients who were discharged with a pending COVID-19 test received follow up calls on Days 1, 4 and 8. The objective of our program was to screen and provide referrals for health-related social needs (HRSNs); conduct clinical screening for worsening symptoms; and deliver risk-reduction strategies for vulnerable individuals. Retrospective chart review was conducted on all patients in this cohort to collect demographic information, testing results, and outcomes of clinical symptom and HRSN screening. Our primary outcome measurement was the need for clinical reassessment and referral for an unmet HRSN.\nResults\nFrom April 24th to June 29th, 2020, we made calls to 1,468 patients tested for COVID-19 and discharged home. On Day 4, we reached 67.0% of the 1,468 patients called. Of these, 15.9% were referred to a PA out of concern for clinical worsening and 12.4% were referred to an ED Patient Navigator for HRSNs.

This multi-faceted syndrome has wide-ranging impacts which, if left untreated, can lead to adverse mental health conditions including depression, anxiety, and substance use disorders. However, the majority of studies examining CF look solely at clinicians; as a result, there is no information on the impact of CF across other roles that are involved in supporting patient care. We conducted this study to establish the prevalence of CF across both clinical and non-clinical roles in the adult ED setting.\n \nMethods: \nFor this single institution cross-sectional study, all full- and part-time ED staff members who worked at least 50% of their shifts in the ED or within the adult trauma service line were eligible to participate. Using the Professional Quality of Life (ProQOL-5) scale, which measures CF via compassion satisfaction (CS), burnout (BO), and secondary traumatic stress (STS), we assessed for group differences between roles using non-parametric one-way ANOVA.\n \nResults: \nA total of 152 participants (response rate = 38.0%) completed the survey. This included attending physicians (n = 15, 9.7%), resident/fellow physicians (n = 23, 15.1%), staff nurses (n = 54, 35.5%), emergency technicians (n = 21, 13.8%), supportive clinical staff (n = 28, 18.4%), and supportive ancillary staff (n = 11, 7.2%). Across all roles, the majority of respondents had average levels of BO (median = 25.0, IQR 20.0 – 29.0) and STS (median = 23.0, IQR 18.0 – 27.0) coupled with high levels of CS (median = 38.0, IQR 33.0 – 43.0). There was a difference in CS by role (p = .01), with nurses reporting lower CS than attending physicians. STS also differed by role (p = .01), with attending physicians reporting lower STS than both emergency technicians and nurses. Group differences were not seen in BO. \n \nConclusions:\n \nRates of CF subcomponents were similar across all ED team members, including non-clinical staff.

The survey was sent via 3 national pediatric emergency medicine distribution lists, with several follow-up reminders.\nResults\nThere were 46 questionnaires included, completed by PED directors from 25 states. Forty-two sites provided PED volume and admission data for early pandemic (March-July 2020), and a pre-pandemic comparison period (March-July 2019). Mean PED volume decreased > 32% for each studied month, with a maximum mean reduction of 63.6% (April 2020). Mean percentage of pediatric admissions over baseline also peaked in April 2020 at 38.5% and remained 16.4% above baseline by July 2020.\nDuring the study period, 33 (71.1%) sites had decreased provider staffing at some point. Only 3 sites (6.7%) reported decreased faculty protected time. All PEDs reported staffing changes, including decreased mid-level use, increased on-call staff, movement of staff between PED and other units, and added tele-visit shifts. Twenty-six sites (56.5%) raised their patient age cutoff; median was 25 years (IQR 25-28).\nOf 44 sites hosting medical trainees, 37 (84,1%) reported a decrease in trainee number or elimination altogether. Thirty (68.2%) sites had restrictions on patient care provision by trainees: 28 (63.6%) affected medical students, 12 (27.3%) affected residents and 2 (4.5%) impacted fellows. Fifteen sites (34.1 %) had restrictions on procedures performed by medical students (29.5%), residents (20.5%), or fellows (4.5%).\nConclusion\nThis study highlights the marked impact of the COVID-19 pandemic on US PEDs, noting decreased patient volumes, increased admission rates, and alterations in staffing models. During the early pandemic, educational restrictions for trainees in the PED setting disproportionately affected medical students over residents, with fellow experience largely preserved.

This study aimed to describe the incidence and trend of high-risk ED revisits in United States EDs and to investigate factors associated with these revisits.\n \nMethods\n: Data were obtained from the National Hospital Ambulatory Medical Care Survey (NHAMCS), 2010\n–\n2018. Adult ED revisits within 72 hours of a previous discharge were identified using a mark on the Patient Record Form. High-risk revisits were defined as revisits with serious adverse outcomes, including intensive care unit admissions, emergency surgery, cardiac catheterization, or cardiopulmonary resuscitation (CPR) during the return visit. Analyses used descriptive statistics and multivariable logistic regression accounting for NHAMCS's complex survey design.\n \nResults\n: Over the 9-year study period, there were an estimated 37,700,000 revisits, and the proportion of revisits in the entire ED population decreased slightly from 5.1% in 2010 to 4.5% in 2018 (P for trend = 0.02). By contrast, there were an estimated 827,000 high-risk ED revisits, and the proportion of high-risk revisits in the entire ED population remained stable at approximately 0.1%. The mean age of these high-risk revisit patients was 57 years, and 43% were men. Approximately 6% of the patients were intubated, and 13% received CPR. Most of them were hospitalized, and 2% died in the ED. Multivariable analysis showed older age (65+ years), Hispanic ethnicity, daytime visits, and arrival by ambulance during the revisit were independent predictors of high-risk revisits.\n \nConclusions\n: High-risk revisits accounted for a relatively small fraction (0.1%) of the ED visits. Over the time period of NHAMCS survey between 2010-2018, this fraction remained stable. We identified factors during the return visit that could be used to label high-risk revisits for timely intervention.", "language": "en", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

Ehrhart theory then gives us a formula for the biEulerian polynomial, which we use to show that this polynomial is real-rooted and that the \\(h\\)-vector of the bipermutahedral fan is log-concave and unimodal. We describe all the deformations of the bipermutahedron; that is, the ample cone of the bipermutahedral toric variety. We prove that among all polytopes in this family, the bipermutahedron has the largest possible symmetry group. Finally, we show that the Minkowski quotient of the bipermutahedron and the harmonic polytope equals 2.\n \nMathematics Subject Classifications: 52B20, 52B05, 05A15\n \nKeywords: Polytope, bipermutahedron, bipermutations, descents, \\(f\\)-vector, \\(h\\)-vector, unimodular triangulation, Ehrhart polynomial, real-rooted polynomial, deformation cone", "language": "en", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

However, legal challenges to the practice have been largely unsuccessful due to immigration law’s “exceptionality.” Placing recent litigation carried out against immigration detention during the COVID-19 pandemic within the context of the judiciary’s approach to immigration, this Article argues that litigation is an extremely limited strategic avenue to curtail the use of immigration detention. I then argue that anti-immigration detention advocates should attempt to incorporate their agenda into criminal legal reform and decarceration efforts. This is important for both movements. Normatively, immigration detention raises comparable issues: Namely, that jailing people is, on the one hand, an extreme and cost-ineffective form of social control, and on the other, a tool to marginalize or “otherize” entire communities. Furthermore, there is evidence that ongoing efforts to decarcerate states and localities may be foiled by immigration detention. To the extent, therefore, that decarceration reforms are based on commitments to freedom or condemnation of the extensive use of carceral institutions, they are incomplete and even dangerous without including measures to address immigration detention. Immigration advocates, on the other hand, are more likely to succeed by placing the anti-immigration detention agenda within the scope of larger criminal legal reform than by pursuing immigration detention reform or through litigation.</em></p>", "language": null, "license": { "name": "All rights reserved", "short_name": "Copyright", "text": "© the author(s).

It is a strange combination: Generally speaking the companies do the bad things on behalf of shareholders—to make more money for them—but then the securities regulators come in and fine them for defrauding shareholders.” </em></p>\n<p><em>-Matt Levine</em></p>\n<p><em>Securities litigation is a virtually inevitable fact of life for any public company. Often, investors sue because the firm’s managers engaged in fraud that directly harmed the shareholders—say, by doctoring the firm’s financials, or lying about known business prospects. However, shareholders also sue their companies when those companies engage in conduct that primarily harms a different set of constituents. When a drug on the market proves to have dangerous side effects, a faulty car battery bursts into flames, or an oil rig explodes, it’s difficult to say that the most direct victims are the companies’ shareholders. Yet shareholders commonly sue under the federal securities laws based on precisely this kind of conduct, on the basis that the managers should have better disclosed the underlying facts, and investors were harmed by the resulting drop in stock price because they did not. In recent years, these cases, dubbed “event-driven securities litigation,” have become more common and have drawn increasing criticism on the grounds that they are opportunistic and generally lack merit. However, there has so far been no comprehensive examination of these lawsuits.</em></p>\n<p><em>This paper seeks to fill the gap by investigating the prevalence and attributes of these lawsuits. In a sample from 2010 to 2015, I find that roughly 16.5% of securities class actions arise from conduct where the most direct victims are not shareholders. However, I find that these cases have roughly a 20% lower likelihood of being dismissed and settle for significantly higher amounts. These lawsuits are also more likely to be brought against large defendant firms, more likely to involve an institutional investor as a lead plaintiff, and much more likely to involve a non-SEC investigation or inquiry than cases where the primary victims are shareholders. Many of these attributes are used in the literature as proxies for merit. However, I argue that the merit of these cases is not clear-cut. Further, from a policy perspective, while these cases may have deterrence value, they may not be an optimal means to monitor corporate misconduct that harms outsiders.</em></p>", "language": null, "license": { "name": "All rights reserved", "short_name": "Copyright", "text": "© the author(s).

From COVID-19 to Trump’s first impeachment trial, whistleblowers have played a vital role in bringing to light information otherwise impossible to obtain. While the value that whistleblowers bring to government, organizations, and society has always been immeasurable, it is still the case that whistleblowers ultimately suffer a disastrous fate. They have made the decision to speak out against wrongdoing, often risking their jobs, livelihoods, and ability to thrive in their respective industry due to harassment, demotion, exclusion, or termination. As a result, the emotional harm that they naturally suffer is significant. In some cases, it even leads to depression, suicide, and other devastating consequences. Yet one of the most prominent federal whistleblower programs today—the Securities and Exchange Commission’s (SEC) whistleblower provisions under the Dodd-Frank Act—is an anomaly in numerous respects. It is one of the only federal whistleblower programs that fails to offer non-economic, emotional damages as a remedial provision. After examining personal accounts of whistleblower experiences, this Article will conduct a comparative analysis of the damages available under the SEC’s whistleblower program of the Dodd-Frank Act as compared to several other notable whistleblowing statutes, some of which are also within the domain of the investment markets. This Article will then propose a theoretical basis in support of emotional damages for whistleblowers by both incorporating deterrence theory under economic principles in tort law and undergoing a “rights vs. remedies” analysis that considers the substantive and procedural considerations of ensuring that whistleblowers, in their pursuit of justice against their retaliators, are truly made whole.</em></p>", "language": null, "license": { "name": "All rights reserved", "short_name": "Copyright", "text": "© the author(s).

The conventional wisdom is that Lear gave away his kingdom too soon and left himself vulnerable to predatory heirs. This has been referred to as the “King Lear Problem.” </em></p>\n<p><em>The conventional wisdom is wrong. Lear’s succession plan failed because he waited too long. Like Lear, those who control family businesses are often reluctant to step aside. For example, until he was well into his nineties, Sumner Redstone declared that his succession plan was to never die. The predictable consequence was litigation that engulfed the companies he controlled, including CBS and Viacom. Yet, despite its importance, the question of family-business succession has been neglected by legal scholars. Using King Lear as a framing device, this Article identifies obstacles to succession and shows how legislative initiatives, judicial intervention, and private ordering can facilitate the timely transfer of ownership and control across generations.</em></p>", "language": null, "license": { "name": "All rights reserved", "short_name": "Copyright", "text": "© the author(s).

use of the emerging form. To this end, we conducted a narrative-elicitation task with 5-year-old children and adults across four typologically-distinct languages with different new/given markers: English, Hindi, Mandinka and Spanish. Our starting assumption was that the Hindi numeral ‘ek’ (one) is developing into an indefinite article, which should delay children’s acquisition because of its optional use to introduce discourse referents. Supporting the Optionality Hypothesis, Experiment 1 revealed that obligatory markers are acquired earlier than optional markers. Experiment 2 focused on Hindi and showed that 10-year-old children’s use of ‘ek’ to introduce discourse characters was higher than 5-year-olds’ and comparable to adults’, replicating this pattern of results in two different cities in Northern India. Lastly, a follow-up study showed that Mandinka-speaking children and adults made use of all available discourse markers when tested on a familiar story, rather than with pictorial prompts, highlighting the importance of using culturally-appropriate methods of narrative elicitation in cross-linguistic research. We conclude by discussing the implications of article grammaticalization for common ground management in a speech community.<o:p></o:p></p>", "language": "eng", "license": { "name": "Creative Commons Attribution 4.0", "short_name": "CC BY 4.0", "text": "Attribution — You must give appropriate credit, provide a link to the license, and indicate if changes were made.

In 2013, center-left President Michelle Bachelet proposed tuition-free higher education for Chile’s bottom 70%, fueling controversy due to the uncertainty and unexpected medium and long-term consequences. This study analyzes how the free-tuition policy was developed, the actors involved, the political discourse deployed during its implementation, and the strategy used to make this policy a reality. Using semi-structured interviews with key actors, such as policymakers and scholars, and a review of newspaper columns, we wanted to explore how politicians and bureaucrats \ntranslated \nthe students’ demands into the free-tuition policy. Our findings suggest that the policy translation process involved former student leaders, free-tuition policy prioritization, and a quick, straightforward implementation process that enabled the government to fulfill its promise.", "language": "en", "license": null, "keywords": [ { "word": "Free-tuition" }, { "word": "Higher Education" }, { "word": "Policy" }, { "word": "Chile" } ], "section": "Articles", "is_remote": true, "remote_url": "https://escholarship.org/uc/item/5jc6q534", "frozenauthors": [ { "first_name": "Daniela", "middle_name": "", "last_name": "Veliz", "name_suffix": "", "institution": "Pontificia Universidad Católica de Chile", "department": "" }, { "first_name": "Astrid", "middle_name": "", "last_name": "Pickenpack", "name_suffix": "", "institution": "University of Pennsylvania", "department": "" }, { "first_name": "Cristóbal", "middle_name": "", "last_name": "Villalobos", "name_suffix": "", "institution": "Pontificia Universidad Católica de Chile", "department": "" } ], "date_submitted": "2021-08-26T14:18:29Z", "date_accepted": "2021-08-26T14:18:29Z", "date_published": "2022-09-28T17:57:38Z", "render_galley": null, "galleys": [ { "label": "", "type": "pdf", "path": "https://journalpub.escholarship.org/bre/article/63470/galley/48877/download/" } ] }, { "pk": 54221, "title": "Codetermination and Power in the Workplace", "subtitle": null, "abstract": "How does codetermination—entitling workers to participate in firm governance, either through membership on company boards or the formation of works councils—affect worker welfare and corporate decision-making?

Pervasive Monopsony Power and Freedom in the Labor Market", "subtitle": null, "abstract": "Abstract: One common metric of monopsony power is the quit elasticity, measuring how much more likely a worker is to quit a job in response to a wage change. Experimental and quasi-experimental variation in wages across workers within a given job results in quit elasticities in the 2-3 range, implying that a 10% reduction in wages increases the probability of quitting by 20-30%. In a model with monopsonistic employers, a quit elasticity of 2-3 also implies that workers are paid about 80-85% of the value they produce. These results indicate that employer power is pervasive. We present observational evidence that historically disadvantaged groups have systematically lower quit elasticities, indicating they face even greater employer power. Because monopsony power comes from an inability of workers to voluntarily switch jobs, the quit rate and especially the quit elasticity can be a useful metric for judging the health of the labor market. Pervasive employer power alters the analysis of labor market policy in a number of important ways.", "language": "en", "license": null, "keywords": [ { "word": "Monopsony power, quit elasticity, wages, job ladder, domination, historically disadvantaged groups, labor market indicators" } ], "section": "B.\tAssessing economic claims in philosophy and employment law", "is_remote": true, "remote_url": "https://escholarship.org/uc/item/3t61g53n", "frozenauthors": [ { "first_name": "Suresh", "middle_name": "", "last_name": "Naidu", "name_suffix": "", "institution": "", "department": "" }, { "first_name": "Michael", "middle_name": "", "last_name": "Carr", "name_suffix": "", "institution": "", "department": "" } ], "date_submitted": "2022-09-28T17:16:09Z", "date_accepted": "2022-09-28T17:16:09Z", "date_published": "2022-09-28T07:00:00Z", "render_galley": null, "galleys": [ { "label": "", "type": "pdf", "path": "https://journalpub.escholarship.org/lawandpoliticaleconomy/article/54218/galley/40979/download/" } ] }, { "pk": 54212, "title": "Preface to Special Issue: Not So Free to Contract: How Unequal Workplace Power Undercuts the “Freedom of Contract” Framework", "subtitle": null, "abstract": "", "language": "en", "license": null, "keywords": [], "section": "Front Matter", "is_remote": true, "remote_url": "https://escholarship.org/uc/item/8z09s50f", "frozenauthors": [ { "first_name": "Elizabeth", "middle_name": "", "last_name": "Anderson", "name_suffix": "", "institution": "", "department": "" } ], "date_submitted": "2022-09-28T16:58:16Z", "date_accepted": "2022-09-28T16:58:16Z", "date_published": "2022-09-28T07:00:00Z", "render_galley": null, "galleys": [ { "label": "", "type": "pdf", "path": "https://journalpub.escholarship.org/lawandpoliticaleconomy/article/54212/galley/40973/download/" } ] }, { "pk": 54214, "title": "Talking About Private Government: A Review of the Economic Claims Made to Rebut Anderson’s Analysis", "subtitle": null, "abstract": "In \nPrivate Government: How Employers Rule Our Lives (and Why We Don’t Talk About It), \nElizabeth Anderson argues that most people in the United States and other liberal societies spend their working lives under the kind of autocratic rule we would normally associate with communist dictatorships.
