This paper documents a new and important cross-sectional determinant of hedge fund returns, their exposures to sentiment risk, measured as beta of fund returns to fluctuations in sentiment proxies. For a large sample of equity-oriented hedge funds, those whose sentiment beta ranks in the top decile subsequently outperform the bottom decile by 0.67% per month, after controlling for fund’s exposu...

BACKGROUND With a greater emphasis on cost containment in many health care systems, it has become common to evaluate each physician's relative resource use. This study explored the major factors that influence the economic performance rankings of medical clinics in the Korea National Health Insurance (NHI) program by assessing the consistency between cost-efficiency indices constructed using di...

consecutive droughts in sistan and baloochestan province cause water resources restriction and this isa very significant problem for this region. in this study, in order to forecast the drought cycle in 9climatological stations in the province, we used artificial neural networks. the input data wereaverage of annual rainfall data in all stations and also deciles precipitation index, which the f...

This paper revisits Saccone’s (2020) analysis of the impact economic freedom on decile income shares for a panel developed and developing nations during 1980-2014. Saccone found that higher levels corresponded with lower bottom 8 deciles only top 2 deciles. Instead shares, this focuses levels. We find per capita all 10 increases as increases.

OBJECTIVE To study the relationship between low birth weight and the presence of gestational diabetes mellitus (GDM) or peripheral insulin resistance during pregnancy. RESEARCH DESIGN AND METHODS We studied the relationship between peripheral insulin sensitivity (calculated by Matsuda and DeFronzo's oral glucose tolerance test (OGTT)-derived insulin sensitivity index [ISI(OGTT)]) or GDM preva...

OBJECTIVES The mortality outcome of mechanical ventilation, a key intervention in the critically ill, has been variously reported to be determined by intensive care patient volume. We determined the volume-(mortality)-outcome relationship of mechanically ventilated patients whose records were contributed to the Australian and New Zealand Intensive Care Society Adult Patient Database. DESIGN, ...

BACKGROUND Higher-protein diets are associated with decreased adiposity and greater HDL cholesterol than lower protein diets. Whether these benefits can be attributed to a specific protein source (i.e., nondairy animal, dairy, or plant) is unknown, and concerns remain regarding the impact of higher-protein diets on kidney function. OBJECTIVE The objective of this study was to evaluate trends ...

BACKGROUND Under bundled payment initiatives, providers will be held financially responsible for patients' acute and post-acute care costs. Certain patients, termed high utilizers, use disproportionate shares of resources during 1 year. The aim of this study was to identify high utilizers, describe their costs, and determine whether preoperative characteristics predict high utilizer status. S...

This paper investigates the significance of dynamic conditional beta in predicting the cross-sectional variation in expected stock returns. The results indicate that the time-varying conditional beta is alive and well in the cross-section of daily stock returns. Portfolio-level analyses and firm-level cross-sectional regressions indicate a positive and significant relation between dynamic condi...

How do human beings decide when to be selfish or selfless? In this study, we gave testosterone to 25 men to establish its impact on prosocial behaviors in a double-blind within-subjects design. We also confirmed participants' testosterone levels before and after treatment through blood draws. Using the Ultimatum Game from behavioral economics, we find that men with artificially raised T, compar...
