important factor in the prevention of industrial accidents involve of the ability of employees to maintain awareness of the work situation, understand the information it holds, and predict how situations will develop. in this study, we examined the role of fatigue and work overload in predicting work situation awareness among workers. the current study was a cross-sectional study. the sample co...
With the proposal of goal “carbon peak, carbon neutrality”, concept environmental protection has become increasingly popular. To explore characteristics and influencing factors consumers’ green consumption behavior against a dual-carbon background, this study proposed research variables hypotheses about factors. purpose, variables, hypotheses, questionnaire was designed. Consumers in Anhui Prov...
Factor and principal component analyses are widely used in different sciences especially in agricultural science. To determine the factors that create variation between potato cultivars, in normal (non-stress) and water deficit (stress) conditions, two experiments were conducted in the form of randomized complete block design with three replications in summer 2002. Stepwise regression analysis ...
We consider the problem of selecting grouped variables (factors) for accurate prediction in regression. Such a problem arises naturally in many practical situations with the multi-factor ANOVA problem as the most important and well known example. Instead of selecting factors by stepwise backward elimination, we focus on estimation accuracy and consider extensions of the LASSO, the LARS, and the...
This research was conducted at Research Farm of Isfahan University of Technology to examine the relations among phonologic, morphologic and physiologic traits and their effects on grain yield of 20 oat (Avena sativa L.) genotypes. A randomized complete block design with three replications was used in each irrigation treatment (i.e. irrigation after 70±3, and 130±3 mm evaporation from class A pa...
Force generated by the perioral musculature is known to be a potent factor that can affect tooth position and malocclusion. To evaluate the influence of the force of the orbicularis oris muscle on incisor position, we determined the maximum and average strengths of the upper lip of male Class I malocclusion patients with a Y-meter, which was devised to measure the vertical closing force of the ...
to study the phenotypic and genotypic diversity of some important agronomic traits associated with yield in white beans, 30 genotypes of white bean were evaluated using a randomized complete block design with four replications in two environments under water stress and non stress conditions. analysis of variance for most of the traits showed significant differences among genotypes, indicating t...
This project sought to determine the utility in using either, or both, of two instruments to diagnose autism, the CARS (Childhood Autism Rating Scale) and the ADOS (Autism Diagnostic Observation Schedule), Modules 1 or 2. Children (n=320) who were seen in the autism diagnostic clinics at the Developmental Disabilities Center of the Kansas University Medical Center, who were under the age of 72 ...
A principal aim of many sciences is to model causal systems well enough to provide insight into their structures and mechanisms and to provide reliable predictions about the effects of policy interventions. To succeed in either of these aims, in general, one must specify a model at least approximately correctly. In the social and behavioral sciences, causal models are often described within any...
