The systematic errors that are induced by a combination of human memory limitations and common survey design and implementation have long been studied in the context of egocentric networks. Despite this, little if any work exists in the area of random error analysis on these same networks; this paper offers a perspective on the effects of random errors on egonet analysis, as well as the effects...

Burnout has been a major concern in the educational settings and it is worth exploring it among English as a Foreign Language (EFL) students and finding its relationship with other factors, such as emotional intelligence (EI), which may help reduce burnout sources. In this light, this study was designed to a) explore Iranian EFL students’ burnout and EI profiles; b) investigate the relationship...

BACKGROUND All quantifications of mortality, morbidity, and other health measures involve numerous sources of error. The routine quantification of random sampling error makes it easy to forget that other sources of error can and should be quantified. When a quantification does not involve sampling, error is almost never quantified and results are often reported in ways that dramatically oversta...

background achievement in university education may be related to one’s emotional intelligent (ei) as well as his/her social skills and emotional control. therefore, it is also probable that the ei be associated with academic and occupational achievement in medical students. objectives the aim of this study was evaluation of the relation between ei and academic achievement of students working in...

In this paper, the effects of random errors on the oscillating behaviors have been studied theoretically and numerically in a prototypical coupled nonlinear oscillator. Two kinds of noises have been employed respectively to represent the measurement errors accompanied with the parameter specifying the distance from a Hopf bifurcation in the Stuart-Landau model. It has been demonstrated that whe...

This research investigated effects of narcissism and emotional intelligence (EI) on popularity in social networks. In a longitudinal field study, we examined the dynamics of popularity in 15 peer groups in two waves (N = 273). We measured narcissism, ability EI, and explicit and implicit self-esteem. In addition, we measured popularity at zero acquaintance and 3 months later. We analyzed the da...

Given sets Φ1 = {φ11, . . . , φ1u(1)}, . . . ,Φz = {φz1, . . . , φzu(z)} of boolean formulas, a formula ω follows from the conjunction ∧ Φi = ∧ φij iff ¬ω ∧ ∧z i=1 Φi is unsatisfiable. Now assume that, given integers 0 ≤ ei < u(i), we must check if ¬ω ∧ ∧z i=1 Φ ′ i remains unsatisfiable, where Φ ′ i ⊆ Φi is obtained by deleting ei arbitrarily chosen formulas of Φi, for each i = 1, . . . , z. I...

purpose : to determine the prevalence of refractive condition and its risk factors among students in mashhad . methods : a total of 2510 students representing a cross-sectional of the population of mashhad were sampled using random cluster sampling strategy. primary and middle school students underwent cycloplegic refraction. the refractive errors of high school students were measured using non...

objective: the morphology of anterior cerebral artery (aca) in patients with hydrocephalus was analyzed (hcp), and its importance was discussed in maintaining cerebral perfusion. materials & methods: two groups were created for the study. group 1; patients with hydrocephalus and group 2; as control group without hcp. in both groups, the length of the a2 segment of aca was measured from its orig...
