What are the benefits of hosting a major league sports franchise?
Over the last few decades the number of U.S. metropolitan areas large enough to host a franchise from one of the four major professional sports leagues has soared. Even as major league baseball, football, basketball and hockey have expanded to include more franchises, demand by metro areas continues to exceed supply. Metro areas have thus been forced to compete with each other to retain and attract franchises. ; The resulting large public spending on new sports facilities has been quite controversial. Usually these costly projects are justified by claims that hosting a sports franchise spurs local economic development by creating numerous new jobs and boosting local tax revenue. Independent economic studies suggest, however, that such benefits are much smaller than the outlay of public funds. ; Does this mean that public funding of sports franchises is not justified? Perhaps not. Rappaport and Wilkerson review the current rush by metro areas to build sports facilities. They lay out the arguments both in favor of and against using public funds to do so. They show why the job creation and tax revenue benefits from hosting a major league franchise fall far short of typical public outlays on constructing a new sports facility. Finally, they argue that the large quality-of-life benefits associated with hosting a major league team may justify the public outlays.Professional sports
March Madness in the Collegiate Sport Workplace: Cultural Implications for Sport Employees
Drawing upon Schein and Schein’s three-level conceptual framework of organizational culture, the purpose of this study was to examine how organizational culture and a sense of community manifest within intercollegiate athletics departments during March Madness. Considering the popularity of intercollegiate sport and March Madness, it is important for scholars to understand how organizational culture may influence the attitudes and behaviors of collegiate sport employees in the workplace. Thus, semi-structured interviews and observations were conducted to better understand how culture, community, and the phenomenon of March Madness traverse. Analysis of the data revealed a unique organizational culture within intercollegiate athletics departments, distinguishing them from other nonsport organizations. It was also discovered that socialization processes occur during March Madness, which can foster a sense of community. Implications for these findings are discussed and practical recommendations for collegiate athletics departments are provided
The “New” Student-Athlete: An Exploratory Examination of Scholarship eSports Players
The growth and popularity of eSports cannot be understated. The domain has become so mainstream that colleges and universities are rapidly beginning to launch eSports programs within their athletics departments. In this study, the authors interviewed 33 student-athletes receiving scholarships for participating in eSports at one institution. In all, the identity and social capital of athletes in this “new” athletic arena were explored and compared with previous studies examining “traditional” athletes. The implications of the similarities and differences are discussed and ideas for future research into this emerging field are presented
The Majorana Neutrinoless Double-Beta Decay Experiment
The proposed Majorana double-beta decay experiment is based on an array of
segmented intrinsic Ge detectors with a total mass of 500 kg of Ge isotopically
enriched to 86% in 76Ge. A discussion is given of background reduction by:
material selection, detector segmentation, pulse shape analysis, and
electro-formation of copper parts and granularity. Predictions of the
experimental sensitivity are given. For an experimental running time of 10
years over the construction and operation of Majorana, a half-life sensitivity
of ~4x10^27 y (neutrinoless) is predicted. This corresponds to an effective
Majorana mass of the electron neutrino of ~0.03-0.04 eV, according to recent
QRPA and RQRPA matrix element calculations.Comment: 10 pages, 7 figure
Integrated genomic analyses of ovarian carcinoma
A catalogue of molecular aberrations that cause ovarian cancer is critical for developing and deploying therapies that will improve patients’ lives. The Cancer Genome Atlas project has analysed messenger RNA expression, microRNA expression, promoter methylation and DNA copy number in 489 high-grade serous ovarian adenocarcinomas and the DNA sequences of exons from coding genes in 316 of these tumours. Here we report that high-grade serous ovarian cancer is characterized by TP53 mutations in almost all tumours (96%); low prevalence but statistically recurrent somatic mutations in nine further genes including NF1, BRCA1, BRCA2, RB1 and CDK12; 113 significant focal DNA copy number aberrations; and promoter methylation events involving 168 genes. Analyses delineated four ovarian cancer transcriptional subtypes, three microRNA subtypes, four promoter methylation subtypes and a transcriptional signature associated with survival duration, and shed new light on the impact that tumours with BRCA1/2 (BRCA1 or BRCA2) and CCNE1 aberrations have on survival. Pathway analyses suggested that homologous recombination is defective in about half of the tumours analysed, and that NOTCH and FOXM1 signalling are involved in serous ovarian cancer pathophysiology.National Institutes of Health (U.S.) (Grant U54HG003067)National Institutes of Health (U.S.) (Grant U54HG003273)National Institutes of Health (U.S.) (Grant U54HG003079)National Institutes of Health (U.S.) (Grant U24CA126543)National Institutes of Health (U.S.) (Grant U24CA126544)National Institutes of Health (U.S.) (Grant U24CA126546)National Institutes of Health (U.S.) (Grant U24CA126551)National Institutes of Health (U.S.) (Grant U24CA126554)National Institutes of Health (U.S.) (Grant U24CA126561)National Institutes of Health (U.S.) (Grant U24CA126563)National Institutes of Health (U.S.) (Grant U24CA143882)National Institutes of Health (U.S.) (Grant U24CA143731)National Institutes of Health (U.S.) (Grant U24CA143835)National Institutes of Health (U.S.) (Grant U24CA143845)National Institutes of Health (U.S.) (Grant U24CA143858)National Institutes of Health (U.S.) (Grant U24CA144025)National Institutes of Health (U.S.) (Grant U24CA143866)National Institutes of Health (U.S.) (Grant U24CA143867)National Institutes of Health (U.S.) (Grant U24CA143848)National Institutes of Health (U.S.) (Grant U24CA143843)National Institutes of Health (U.S.) (Grant R21CA135877
Global overview of the management of acute cholecystitis during the COVID-19 pandemic (CHOLECOVID study)
Background: This study provides a global overview of the management of patients with acute cholecystitis during the initial phase of the COVID-19 pandemic. Methods: CHOLECOVID is an international, multicentre, observational comparative study of patients admitted to hospital with acute cholecystitis during the COVID-19 pandemic. Data on management were collected for a 2-month study interval coincident with the WHO declaration of the SARS-CoV-2 pandemic and compared with an equivalent pre-pandemic time interval. Mediation analysis examined the influence of SARS-COV-2 infection on 30-day mortality. Results: This study collected data on 9783 patients with acute cholecystitis admitted to 247 hospitals across the world. The pandemic was associated with reduced availability of surgical workforce and operating facilities globally, a significant shift to worse severity of disease, and increased use of conservative management. There was a reduction (both absolute and proportionate) in the number of patients undergoing cholecystectomy from 3095 patients (56.2 per cent) pre-pandemic to 1998 patients (46.2 per cent) during the pandemic but there was no difference in 30-day all-cause mortality after cholecystectomy comparing the pre-pandemic interval with the pandemic (13 patients (0.4 per cent) pre-pandemic to 13 patients (0.6 per cent) pandemic; P = 0.355). In mediation analysis, an admission with acute cholecystitis during the pandemic was associated with a non-significant increased risk of death (OR 1.29, 95 per cent c.i. 0.93 to 1.79, P = 0.121). Conclusion: CHOLECOVID provides a unique overview of the treatment of patients with cholecystitis across the globe during the first months of the SARS-CoV-2 pandemic. The study highlights the need for system resilience in retention of elective surgical activity. Cholecystectomy was associated with a low risk of mortality and deferral of treatment results in an increase in avoidable morbidity that represents the non-COVID cost of this pandemic
Survey of Western U.S. Electric Utility Resource Plans
We review long-term electric utility plans representing ~;;90percent of generation within the Western United States and Canadian provinces. We address: what utility planners assume about future growth of electricity demand and supply; what types of risk they consider in their long-term resource planning; and the consistency in which they report resource planning-related data. The region is anticipated to grow by 2percent annually through 2020?before Demand Side Management. About two-thirds of the utilities that provided an annual energy forecast also reported energy efficiency savings projections; in aggregate, they anticipate an average 6.4percent reduction in energy and 8.6percent reduction in peak demand by 2020. New natural gas-fired and renewable generation will replace retiring coal plants. Although some utilities anticipate new coal-fired plants, most are planning for steady growth in renewable generation over the next two decades. Most planned solar capacity will come online before 2020, with most wind expansion after 2020. Fuel mix is expected to remain ~;;55percent of total generation. Planners consider a wide range of risks but focus on future demand, fuel prices, and the possibility of GHG regulations. Data collection and reporting inconsistencies within and across electric utility resource plans lead to recommendations on policies to address this issue
