Aggression is part of South African society and has implications for the mental health of persons living in South Africa. If parents are aggressive adolescents are also likely to be aggressive and that will impact negatively on their mental health. In this article the nature and extent of adolescents’ experiences of aggression and aggressive behaviour in the family are investigated. A deductive...

Methods dealing with only one variable are called univariate methods. Methods dealing with more than one variable at once are called multivariate methods. Using univariate methods natural systems cannot be described satisfactorily. Nature is multivariate. That means that any particular phenomenon studied in detail usually depends on several factors. For example, the weather depends on the varia...

background: obesity may lead to various morbidity including liver diseases. the present study was done to determine which obesity indices, including body mass index (bmi), waist circumference (wc), waist to hip ratio (whr), and waist to height ratio (whtr) have the stronger association with rising levels of alanine aminotransferase (alt). material and methods: of 6143 subjects aged ≥ 10 years o...

In prior research we have shown how linear structural equation models and computer programs (e.g., LISREL) may be simply and directly used to provide alternatives for the traditional biometric twin design. We use structural equations and path models to define biometric group differences, we write traditional common-factor models in the same way, and then we take a detailed look at some alternat...

Simple quantitative evaluations of isolate behavioral elements (i.e. frequencies, durations, per cent distributions) are not representative of the whole behavioral structure [1]. As suggested in a landmark paper from Spruijt and Gispen [2], it is only through the evaluation of the inter-relations among behavioral elements that it is possible to explore behavior from very different points of vie...

As part of fMRI data analysis, the pyhrf package provides a set of tools for addressing the two main issues involved in intra-subject fMRI data analysis: (1) the localization of cerebral regions that elicit evoked activity and (2) the estimation of activation dynamics also known as Hemodynamic Response Function (HRF) recovery. To tackle these two problems, pyhrf implements the Joint Detection-E...

9 Multivariate analyses of carcass traits for Angus cattle, consisting of 6 traits recorded 10 on the carcass and 8 auxiliary traits measured by ultra-sound scanning of live animals, 11 are reported. Analyses were carried out by restricted maximum likelihood, fitting a 12 number of reduced rank and factor-analytic models for the genetic covariance matrix. 13 Estimates of eigen-values and -vecto...

in this study the data of 2332 lambs from 815 dams and 61 sires, collected during 1993-2004 in kermani sheep breeding station were used to estimate phenotypic, genetic and environmental trends for birth weight (bw), weaning weight (ww), 6 months weight (6mw), 9 months weight (9mw) and yearling weight (yw). heritability estimates were determined for each trait using derivative free reml procedur...
