An ergodic wideband MIMO channel simulator based on the geometrical T-junction scattering model for vehicle-to-vehicle communications
2010
In this paper, a wideband multiple-input multiple-output (MIMO) simulation model for vehicle-to-vehicle (V2V) channels in T-junction propagation environments is proposed. This simulation model takes the exact relationship between the angle-of-arrival (AOA) and the angle-of-departure (AOD) into account. In order to determine the parameters of the simulation model, the Riemann sum method (RSM) is applied. Furthermore, the statistical and ergodic properties of the simulation model are studied. Closed-form solutions are derived for the space-time-frequency cross-correlation function (STF-CCF), the two-dimensional (2D) spatial cross-correlation function (CCF), the temporal autocorrelation functi…
The child with overgrowth between clinical variability and genetic heterogeneity
2020
Either in the newborn or in the child overgrowth can be generalized or localized if it is limited to one or more body regions. When overgrowth depends on a metabolic imbalance, or it is constitutional, the excessive growth can be the only clinical sign. In most cases genomic or epigenetic alterations, which affect factors involved in cell proliferation and/or regulation of gene expression (observed also in tumours), are related to overgrowth syndromes, in which excess growth may be associated with dysmorphic features, neuromotor/intellectual disabilities and behavioural disorders. These rare conditions are characterized by clinical and molecular overlap. The paper describes the cases of thr…
Self-construals, conflict styles, and religious identification in India
2013
Purpose – This paper aims to explore the relationships between self-construals, religious identification, and conflict styles in India. Design/methodology/approach – Data were gathered in India (n=1,108) among Hindus (n=744) and Muslims (n=364) in various organizations throughout India. Conflict styles were measured using Oetzel's conflict style measure. Self-construal was measured using Singelis' self-construal measure. Pearson correlations and multiple regressions were conducted. Findings – Correlation analysis showed significant negative correlation between the independent and interdependent self-construal. Multiple hierarchical regression modeling demonstrated significant interactions …
Attachment anxiety and implicit self-concept of neuroticism: Associations in women but not men
2015
Abstract Previous research has shown that adult attachment-related anxiety is associated with the explicit self-concept of neuroticism. It remains to be clarified whether attachment anxiety is related to the implicit self-concept of neuroticism. There is evidence that gender can moderate the strength of correlation between implicit and explicit measures. The Experiences in Close Relationships scale and the NEO Five-Factor Inventory (NEO-FFI) were administered to 106 healthy adults along with an Implicit Association Test assessing neuroticism. Attachment anxiety correlated with NEO-FFI neuroticism, regardless of gender. Attachment anxiety was correlated with neuroticism as measured by the IA…
Does Self-efficacy Matter? On the Correlation of Self-efficacy and Creativity in IT Education
2019
Self-efficacy belief affects humans in life, action and work. Higher self-efficacy enables stronger contribution in fulfilling tasks, helping others in a team, and survive when facing obstacles and failures. Also creativity correlates to higher self-efficacy. At the same time, design is a powerful skill in note-making, improving the student’s understanding of the undergoing topic in a class. Note-making, when consisting of recorded writings, self-drawn images and other supportive subjects like structural analyses, charts, ad-hoc notes, detailed features and verbal links to related themes, forms a fundamental skill and ability in learning and applying new motifs and patterns. We executed dur…
A Comparative Assessment of Listening Span and Self-Efficacy in Simultaneous Interpreting Training
2021
This study compares the results obtained from a group of interpreting trainees in an adapted listening span test (cognitive dimension), with those obtained from this same group in two self-efficacy tests (personality dimension). The objective is to assess the predictive value of these tests with respect to the scores obtained by the subjects in a simultaneous interpreting test. The analysis of data leads us to the conclusion that, at least in an initial training phase in simultaneous interpreting, only the cognitive factors (measured here in terms of listening span) show a significant and positive predictive capacity of the quality in simultaneous interpreting. In this regard, personality f…
THE IMPACT OF FAMILY AND INDIVIDUAL FACTORS ON 4TH GRADE STUDENTS’ SELF-CONFIDENCE IN READING LITERACY: RESULTS FROM PIRLS 2016
2021
The self-confidence of a child and an adult is associated with performance and achievement results. It is well-studied, and the correlation has been proved that higher self-efficacy leads to higher achievements and performance, including better performance in reading literacy. It is also known that both a family and a home environment have a tremendous impact on the child’s development and academic performance. This article focuses on the 4 th graders and their family factor impact on the development of a child’s self-confidence and concepts related to self-confidence. The purpose of this article is to define concepts that are closely related to self-confidence and to identify family factor…
Meta-analysis of the relationship between teachers’ self-efficacy and attitudes toward inclusive education
2022
Abstract This meta-study aims to examine the size of the relationship between teachers' self-efficacy and attitudes toward inclusive education of K-12 students with special educational needs and to identify potential moderators (publication, sample, and research procedure characteristics). We synthesized the research conducted from 1994 to 2018, and 41 studies were included. Bare-bones meta-analysis with random effect model revealed a sample size weighted correlation coefficient between teachers’ self-efficacy and attitudes as r ¯ = 0.35 (CI = 0.31-0.39). The between-study variations were not associated with hypothesized publication and sample characteristics. However, the self-efficacy me…
RELATIONSHIPS AND DIFFERENCES IN IMPLICITE INTELLIGENCE, PERCEIVED SOCIAL SUPPORT, AND PERCEIVED ACADEMIC SELF-EFFICACY AMONG COMPREHENSIVE SCHOOL ST…
2020
The purpose of this study was to explore relationships of implicit intelligence, perceived social support and perceived academic self-efficacy and to identify how these factors influence academic achievements amongst youth, as well as implement adaption of the revised implicit theories of intelligence (self-theory) scale (De Castell & Byrne, 2015) in Latvia. The research was based on implicit intelligence, perceived social support and academical self-efficacy theories. Nowadays, a growing amount of attention is focused on the reasons driving the academic achievements, self-belief and cumulates conversations about the importance of a social support. According to other scientists’ notes, …
Determination of the chiral couplingsL10andC87from semileptonicτdecays
2008
Using recent precise hadronic {tau}-decay data on the V-A spectral function, and general properties of QCD such as analyticity, the operator product expansion, and chiral perturbation theory, we get accurate values for the QCD chiral order parameters L{sub 10}{sup r}(M{sub {rho}}) and C{sub 87}{sup r}(M{sub {rho}}). These two low-energy constants appear at order p{sup 4} and p{sup 6}, respectively, in the chiral perturbation theory expansion of the V-A correlator. At order p{sup 4} we obtain L{sub 10}{sup r}(M{sub {rho}})=-(5.22{+-}0.06)x10{sup -3}. Including in the analysis the two-loop (order p{sup 6}) contributions, we get L{sub 10}{sup r}(M{sub {rho}})=-(4.06{+-}0.39)x10{sup -3} and C{s…
