INTRODUCTION Time management skills are essential for nursing students' success, and development of clinical competence. The purpose of this study was to determine the relationship between time management skills and anxiety and academic motivation of nursing students in Tehran medical sciences universities in 2015. METHODS This cross-sectional study was carried out on 441 nursing students in ...

INTRODUCTION The study of the distribution of any variable in marine environment generally begins by a sampling experiment. Usually, the collection of samples follows a procedure, often fixed in advance, that takes into account the general distribution of the water masses for a given region. However, much attention may be devoted to the actual structure of the water column present below the shi...

Stratified random sampling (SRS) is a fundamental sampling technique that provides accurate estimates for aggregate queries using a small size sample, and has been used widely for approximate query processing. A key question in SRS is how to partition a target sample size among different strata. While Neyman allocation provides a solution that minimizes the variance of an estimate using this sa...

entrepreneurship is considered as an appropriate approach to accelerate economic development and provide employment opportunities. with this regard, entrepreneurial intention is the main determinant factor in deciding to be an entrepreneur. in order to obtain sufficient knowledge about entrepreneurship and its determinants, entrepreneurial intention of payame noor university students was studie...

The research policy community has produced a significant body of empirical research on benefits of cooperative research between industry and university. However, in spite of a lively policy debate on the subject, it has all but ignored empirical Ž . study on the ‘‘costs’’ or unintended consequences of these activities e.g., erosion of academic freedom . In fact, only four empirical articles ass...

The experiments were conducted for monitoring crop area by spatial sampling methods in a winter wheat main production region with a size of 42Km×42Km in Hengshui City, Hebei Province in China to optimize designs of the frameworks and elements (sample size, sample-square dimension), based on Remote Sensing (RS) and Geographical Information System (GIS) techniques. 5 sample-square dimension level...

Sensitivity analysis is a key part of a comprehensive energy simulation study. Monte-Carlo techniques have been successfully applied to many simulation tools. Several sampling techniques have been proposed in the literature; however to date there has been no comparison of their performance for typical building simulation applications. This paper examines the performance of simple random, strati...

The paper presents a model that extends the stochastic finite element method to the modelling of transitional energetic–statistical size effect in unnotched quasibrittle structures of positive geometry (i.e. failing at the start of macro-crack growth), and to the low probability tail of structural strength distribution, important for safe design. For small structures, the model captures the ene...
