We hypothesize that short selling has a disciplining role vis-à-vis firm managers forces them to reduce earnings management. Using firm-level short-selling data for thirty-three countries collected over sample period from 2002 2009, we document significantly negative relationship between the threat of and Tests based on instrumental variable exogenous regulatory experiments offer evidence causal link Our findings suggest functions as an external governance mechanism discipline managers.

This paper proposes a simple back testing procedure that is shown to dramatically improve panel data model's ability produce out of sample forecasts. Here the used forecast mutual fund alphas. Using monthly with an OLS model it has been difficult consistently predict which portfolio managers will above market returns for their investors. provides empirical evidence sorting on estimated alphas populates top and bottom deciles not best worst funds, but those having greatest estimation error....
Avermectin (AVM) is a low-toxic and high-active biopesticide, but it can be easily degraded by UV light. In this paper, biodegradable castor oil-based polyurethanes (CO-PU) are synthesized used as carriers to fabricate new kind of AVM/CO-PU nanoemulsion through an emulsion solvent evaporation method, the chemical structure, colloidal property, AVM loading capacity, controlled-release behavior, foliar adhesion, photostability drug delivery systems investigated. Results show that physically...
ABSTRACT Corporate social responsibility (CSR) disclosure is becoming increasingly important for modern corporations. Focusing on voluntary CSR and drawing upper echelons theory, we propose that the manifestation of managerial preferences (e.g., managers’ professional ethical values standards).

These lead them act self-restraint perceive as opportunity rather a...
Ferroptosis is an iron-dependent regulated form of cell death implicated in various diseases, including cancers, with its progression influenced by peroxidation phospholipids and dysregulation the redox system. Whereas extracellular matrix tumors provides mechanical cues influencing tumor initiation progression, impact on ferroptosis mechanisms remains largely unexplored. In this study, we reveal that heightened tension sensitizes cells to ferroptosis, whereas decreased mechanics confers...

Abstract Fine particulate matter is a well‐known air pollutant threatening public health. Studies have confirmed long‐term exposure to the particles could decrease pulmonary function, induce asthma exacerbation, and chronic obstructive disease, as well increase incidence mortality of lung cancer. A clinical study has explored that prevalence risks vitamin D (VD) deficiency in various disease toxins induced tissue damage. Our current aimed explore mechanism further therapeutic potential VD...
We hypothesize that poor country-level governance, which makes public information less reliable, induces fund managers to increase their use of semipublic information. Utilizing data from international mutual funds and stocks over the 2000–2009 period, we find information-related stock rebalancing can be five times higher in countries with worst quality governance than best. The increases price informativeness but also asymmetry reduces liquidity. It intensified impact liquidity crunch...
