We provide evidence that both firm and establishment entry rates in the US have been increasing over past decade, seemingly ending decline observed previous decades. However, neither job creation destruction nor reallocation show signs of recovery. These conflicting features are reconciled after we control for changes size business units. As a result, conclude dynamism flattened at historically...
abstract lexical knowledge of complex english words is an important part of language skills and crucial for fluent language use (nation, 2001). the present study, thus, was an attempt to assess the role of morphological decomposition awareness as a vocabulary learning strategy on learners’ productive and receptive recall and recognition of complex english words. so 90 sophomores (female and ma...
with the development of internet of things (iot) technologies in recent years, the development of knowledge management systems based on them, as well as the role of these systems in different organizational areas such as staff performance management should be considered. the objective of this study is to design an application based on the iot, and analysis of its role in staff performance impro...
introduction acetic acid bacteria are large group of obligate aerobic gram negative bacteria with the ability to oxidize ethanol to acetic acid (1). they are widely distributed in natural habitats and classified in family acetobacteraceae. members of this family are useful in industrial production of vinegar(2). acetic acid bacteria (aab) can use substrates as glucose, ethanol, lactate or glyc...
The purpose of the present study was to investigate the effect of cognitive rehabilitation on the improvement of attention deficit disorder in patients with hyperactivity disorder, based on quasi-experimental and pretest-posttest design with control group. The statistical population consisted of all patients with a diagnosis of attention deficit hyperactivity disorder (ADHD) in Roozbeh Psychiat...
Today, the multi purpose use of the potential of water resources is considered with the construction of Rainbow trout farms upstream of permanent rivers in order to make optimal use of these resources and increase employment. The direct entry of the effeluent of theses pools into the water of these rivers can affect their water quality. The aim of this study was to determine the effect of rainb...
The paper investigates dynamic linkages between entry and exit rates in Brazilian manufacturing in the context of 231 (four-digit) industries during the 1996– 2005 period. The empirical analysis focuses on the estimation of a dynamic panel data model for entry and exit rates, and controls for the business cycle and structural characteristics, such as industrial concentration and suboptimal scal...
In slope engineering, soils are commonly at unsaturated state. The question of how to apply unsaturated soil mechanics theory to the slope stability analysis has become a hot spot in today’s geotechnical engineering research. Based on the experimental research of how shear strength of residual soil varies with water content, reasonable computation modules can be created. By using limit equilibr...
The cells of perfused rabbit collecting tubules swell and the intercellular spaces widen during osmotic flow of water from lumen to bath induced by antidiuretic hormone (ADH). Ouabain had no influence on these changes. In the absence of net water flow intercellular width was unaffected when tubules were swollen in hypotonic external media. Therefore, during ADH-induced flow widening of intercel...
