Background: The high workload of nurses in hospitals has been identified as a patient safety and worker stress problem. Psychological empowerment is a motivational concept demonstrated in four dimensions: meaning, competence, self-determination, and impact. Objective: This study investigated the relationship between nurses’ workloads and psychological emp...
ôbjective: m any theorists have attempted to illustrate family functions. the aim of this study was to examine the relationship between self-differentiation, mental well-being and welfare and the quality of an individual’s married life, specifically in the framework of bowen's theory. methods: the sample size for this descriptive research project consisted of 560 participants who were chos...
abstract nowadaysphotovoltaic solar cells (pvs) areacknowledged the fastest growing energy technology in the word, however, they only account for only fraction of current global renewable energy capacity. it isrecognized that this incomplete market penetration has been largely a result of the technology’sexcessive cost. so researchers are trying to find innovative, economic way with theaim of ...
We derive a closed form expression for the asymptotic distribution of the LIML estimator for the coefficients of both endogenous and exogenous variables in a partially identified linear structural equation. We extend previous results of Phillips (1989) and Choi and Phillips (1992) where the focus was on IV estimators. We show that partial failure of identification affects the LIML in that its m...
This study aims to design the management model and planning of career promotion path in the employees of Tehran Bank Mellat Branches. The research method is descriptive and survey that was conducted by correlational and structural equations modeling. The statistical population (n=200) of the study included all employees of twenty branches in Tehran's Bank Mellat who were selected as the sample ...
a semi-empirical mathematical model for predicting physical part of ignition delay period in the combustion of direct - injection diesel engines with swirl is developed . this model based on a single droplet evaporation model . the governing equations , namely , equations of droplet motion , heat and mass transfer were solved simultaneously using a rung-kutta step by step unmerical method . the...
results the results show that the individual and demographic factor (idf), organizational factor (of), h & s training factor (tf), workplace-human factor (whf), factor related to type of accident occurrence (taf), h & s risk management system factor (rmsf), and accident time factor (atf) were considered to be effective and significant independent latent factors in occupational injuries. conclus...
in this thesis we will present three topics. we define approximate fixed points in fuzzy normed spaces. also we obtain some necessary and sufficient conditions on the existence of? -fixed points for ? > 0. at the continue some results about approximate fixed points for a class of non-expansive maps on g-metric spaces are obtained and we define approximate fixed points in partial metric spa...
abstract. the purpose of the present article is to determine the effect of knowledge management on organizational agility through the use of structural equations modeling in auto-parts manufacturing companies. for this purpose, along with the review of concepts such as organizational agility and knowledge management, the dimensions and capabilities of knowledge management and organizational agi...
introduction: ethical climate is a part of organizational culture. organizational values deal with ethical issues and determine what is considered ethically correct. the ethical climate of an organization can predict unethical and ethical behaviors. this study aimed to investigate and model the structural equations between the intention to quit and ethical climate, job satisfaction, and organiz...
