"Why does rain fall?": children prefer to learn from an informant who uses noncircular explanations.
These two studies explored 3- and 5-year-olds' evaluation of noncircular and circular explanations, and their use of such explanations to determine informant credibility. Although 5-year-olds demonstrated a selective preference for noncircular over circular explanations (Experiment 1: Long Explanations; Experiment 2: Short Explanations), 3-year-olds only demonstrated a preference for the noncir...
In this study, the effect of management entrenchments on the speed of cash holding adjustment in Iran has been investigated. After designing the management entrenchment evaluation indicators, the transaction information was collected from the Stock Exchange in the five-year period of 2011-2015. The statistical sample consists of 155 companies selected by systematic deletion method. In this rese...
In this study, the pure manganese ferrite nanoparticles and those dispersed in silica were prepared by the sol-gel method. The average size of particles, which is estimated from Scherrer formula, is about 6 nm for pure sample and 5 nm for silica dispersed sample. The particles size values are in agreement with the TEM results. Results of magnetization measurements showed that these samples hav...
Necroptosis, as a novel concept, has been recently introduced in scientific literature. Much of our knowledge about necroptosis comes from ligation of tumor necrosis factor-α to its receptor, TNF receptor 1. Receptor-interacting protein kinase 1, receptor-interacting protein kinase 3 and its substrate, the pseudokinase mixed lineage kinase domain-like protein, have been comprehensively st...
In this paper, the electronic eigenstates and energy spectra of single and two-interacting electrons confined in a concentric double quantum rings with a perpendicular magnetic field in the presence of on-center donor and acceptor impurities are calculated using the exact diagonalization method. For a single electron case, the binding energy of on-center donor and acceptor impurities ar...
background: previous studies indicate a high incidence of digestive cancers along southern parts of caspian sea including mazandaran province. the present study was conducted to further investigate time to occurrence, age distribution and possible risks associated with the incidence time of digestive cancers in the above regions. methods: for this purpose the data of digestive cancer incidenc...
Background: Today, the drilling industry is one of the world's most dangerous occupations because of the many accidents it is facing. Therefore, the study and evaluation of the risks of activities and operations in the drilling industry can be helpful in reducing the accident in this industry. Methods: In this research, the safety and health risk assessment of drilling operations was carried ou...

Influenza and air pollution each pose significant public health risks with large global economic consequences. The common pathways through which harms presents an interesting case of compounding risk via interacting externalities. Using instrumental variables based on changing wind directions, we show increased levels contemporaneous significantly increase influenza hospitalizations. We exploit...
