So You Think You Can Dance? Lessons from the US Private Equity Bubble

This article develops a sociologically informed approach to market bubbles by integrating insights from financial-economic theory with the concepts of voice and dissimulation from other cases of distorted valuation studied by sociologists (e.g., witch hunts, unpopular norms, and support for authoritarian regimes). It draws on unique data—longitudinal interviews with private equity market participants during and after that market’s mid-2000s bubble—to test key implications of two existing theories of bubbles and to move beyond both. In doing so, the article suggests a crucial revision to the behavioral finance agenda, wherein bubbles may pertain less to the cognitive errors individuals make when estimating asset values and more to the sociological and institutionally driven challenge of how to interpret complex social and competitive environments

TLR2 signaling in skin non-hematopoietic cells induces early neutrophil recruitment in response to Leishmania major infection

Neutrophils are rapidly recruited to the mammalian skin in response to infection with the cutaneous Leishmania pathogen. The parasites use neutrophils to establish the disease, however, the signals driving early neutrophil recruitment are poorly known. Here, we identified the functional importance of TLR2 signaling in this process. Using bone-marrow chimeras and immunohistology we identified the TLR2-expressing cells involved in this early neutrophil recruitment to be of non-hematopoietic origin. Keratinocytes are damaged and briefly in contact with the parasites during infection. We show that TLR2 triggering by L. major is required for their secretion of neutrophil-attracting chemokines. Furthermore, TLR2 triggering by L. major phosphoglycans is critical for neutrophil recruitment impacting negatively on disease development, as shown by better control of lesion size and parasite load in Tlr2-/- compared to wild type infected mice. Conversely, restoring early neutrophil presence in Tlr2-/- mice through injection of wild type neutrophils or CXCL1 at the onset of infection resulted in delayed disease resolution comparable to that observed in wild type mice. Taken together, our data demonstrate a new role for TLR2-expressing non-hematopoietic skin cells in the recruitment of the first wave of neutrophils following L. major infection, a process delaying disease control

El abordaje temprano y tratamiento mixto en el manejo de la esquizofrenia

Introduction: Schizophrenia is a psychotic disorder characterized by substantive alteration of mental functioning and effects on the social functionality of affected individuals. Objective: Provide recommendations based on the best available evidence for early approach, pharmacological and psychosocial treatment. Methods: An Evidence-based Clinical Practice Guide (GPC-BE) was developed, adapted through a systematic, rigorous, transparent process, by a working group composed of methodologists and psychiatrists who are experts in the management of schizophrenia. The guide includes four clinical questions and recommendations, we searched for guides that respond to the prioritized topic, guides were pre-selected and evaluated using the “Appraisal of Guidelines for Research and Evaluation II” (AGREE-II) instrument, the one with the best methodological quality was chosen for adaptation. The systematic search for evidence for each clinical question was performed in multiple databases: MEDLINE / Ovid, EMBASE / Ovid, EMB reviews / Ovid. The selection and analysis of evidence was carried out using clinical pairs and methodologists, the recommendations were prepared using the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology. Results: With the participation of the panel of clinical experts from institutes and hospitals in Peru in the management of schizophrenia, four recommendations were established for the early intervention, pharmacological and mixed treatment of adult patients with schizophrenia. Conclusions: The early approach of the first psychotic episode through community mental health centers (CSMC) and specialized hospitals and pharmacological treatment together with standardized psychosocial therapy is recommended. This article summarizes the evidence-based clinical practice guideline developed by a Peruvian public hospital specializing in mental health disorders.Introducción: La esquizofrenia es un trastorno psicótico caracterizado por alteración sustantiva del funcionamiento mental y efectos sobre la funcionalidad social de la persona afectada.

Mortality and pulmonary complications in patients undergoing surgery with perioperative SARS-CoV-2 infection: an international cohort study

Background: The impact of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) on postoperative recovery needs to be understood to inform clinical decision making during and after the COVID-19 pandemic. This study reports 30-day mortality and pulmonary complication rates in patients with perioperative SARS-CoV-2 infection. Methods: This international, multicentre, cohort study at 235 hospitals in 24 countries included all patients undergoing surgery who had SARS-CoV-2 infection confirmed within 7 days before or 30 days after surgery. The primary outcome measure was 30-day postoperative mortality and was assessed in all enrolled patients. The main secondary outcome measure was pulmonary complications, defined as pneumonia, acute respiratory distress syndrome, or unexpected postoperative ventilation. Findings: This analysis includes 1128 patients who had surgery between Jan 1 and March 31, 2020, of whom 835 (74·0%) had emergency surgery and 280 (24·8%) had elective surgery. SARS-CoV-2 infection was confirmed preoperatively in 294 (26·1%) patients. 30-day mortality was 23·8% (268 of 1128). Pulmonary complications occurred in 577 (51·2%) of 1128 patients; 30-day mortality in these patients was 38·0% (219 of 577), accounting for 81·7% (219 of 268) of all deaths. In adjusted analyses, 30-day mortality was associated with male sex (odds ratio 1·75 [95% CI 1·28–2·40], p\textless0·0001), age 70 years or older versus younger than 70 years (2·30 [1·65–3·22], p\textless0·0001), American Society of Anesthesiologists grades 3–5 versus grades 1–2 (2·35 [1·57–3·53], p\textless0·0001), malignant versus benign or obstetric diagnosis (1·55 [1·01–2·39], p=0·046), emergency versus elective surgery (1·67 [1·06–2·63], p=0·026), and major versus minor surgery (1·52 [1·01–2·31], p=0·047). Interpretation: Postoperative pulmonary complications occur in half of patients with perioperative SARS-CoV-2 infection and are associated with high mortality. Thresholds for surgery during the COVID-19 pandemic should be higher than during normal practice, particularly in men aged 70 years and older. Consideration should be given for postponing non-urgent procedures and promoting non-operative treatment to delay or avoid the need for surgery.

Difficult Decoupling: Employee Resistance to the Commercialization of Personal Settings

The market’s tendency to organize personal spheres of life is not always unfettered, and while past studies have identified public discomfort as a bar to market expansion, this study considers a commercialization project that gained public acceptance yet nevertheless failed. The study’s key theoretical insight is that the organizational decoupling required for successful commercialization may complicate companies’ ability to gain employee acceptance. Rich ethnographic data from Motherhood, Inc., an organization offering support and services for new mothers, is leveraged to identify two conditions under which employee resistance may arise and undermine successful commercialization. This article contributes to sociological understandings by theorizing the important role of employees in commercialization and to organizational theory more generally by specifying conditions under which decoupling may be difficult to achieve

Verstehen for Sociology: Comment on Watts

Duncan Watts, in “Common Sense and Sociological Explanations” (AJS 120 [2014]: 313–51) has done our field a great service by raising a question at the heart of the sociological enterprise: What makes for valuable sociology, and when does it improve upon commonsense explanations? Watts makes three key observations that we believe are quite productive to contemplate. First, one may distinguish between two distinct modes of sociological inquiry: a verstehen (Weber 1968; Watts, p. 318) mode that resembles commonsense explanations in that it aims to establish an empathetic link between the readers or users of such accounts and the actors who populate them; and a “causal” mode, which seeks to identify “generalizable causal mechanisms” (Watts, p. 327; cf. Hedström 2005) that can, in principle, generate testable predictions and, thus, be vetted for their causal validity. Second, sociological theories must have greater causal validity than commonsense explanations if sociology is to make good on its promise of being more valuable than mere common sense. Third, in conducting their research, sociologists often focus on the verstehen mode without engaging in the causal mode
