Abstract:
The purpose of this quantitative study was to investigate which bullying rating scale, between the Likert Scale (LS) and the Visual Analogue Scale (VAS), is more appropriate for Grade 4 learners. Although literature verifies the reliability of these two rating scales used to measure bullying in young children, the validity and the suitability of these instruments for young learners has not been extensively explored in the South African context. The concern with bullying in this study has to do with the need for the accurate assessment/measurement of bullying, since a proper understanding of bu

Abstract:
Course evaluation is one of the primary ways of collecting feedback from students at NDSU. Since almost every student in every course submits one at the end of the semester, it generates a lot of data. The data is summarized into text based reports with emphasis on average rating of each question. At one page per course, analyzing these reports can be overwhelming. Furthermore, it is very difficult to identify patterns in the text reports. We combine heat maps and small multiples to introduce a visualization of the data that allows for easier comparison between courses, departments, etc. We de

Abstract:
Researchers interested in measuring people's underlying attitudes towards an object (e.g., abortion) often collect Likert data by administering a survey. Likert data consist of surveyees' responses to statements about the object, where responses fall into ordered categories running from `Strongly agree' to `Strongly disagree' or into a `Don't Know / Can't Choose' category. Two examples of Likert data are used for illustrative purposes. The first dataset was collected by the author from American and British graduate students at Oxford University and contains items measuring underlying abortion

Thesis advisor: Michael Russell<br>For more than a half century surveys and questionnaires with Likert-scaled items have been used extensively by researchers in schools to draw inferences about students; however, to date there has not been a single study that has examined whether alternative item response types on a survey might lead to different results than those obtained with Likert scales in a K-12 setting.

Abstract:
Many psychological scales written in the Likert format include reverse worded (RW) items in order to control acquiescence bias. However, studies have shown that RW items often contaminate the factor structure of the scale by creating one or more method factors. The present study examines an alternative scale format, called the Expanded format, which replaces each response option in the Likert scale with a full sentence. We hypothesized that this format would result in a cleaner factor structure as compared to the Likert format. We tested this hypothesis on three popular psychological scales: t

Abstract:
This paper provides an alternative methodology for the analysis of a set of Likert responses measured on a common attitudinal scale when the primary focus of interest is on the relative importance of items in the set. The method makes fewer assumptions about the distribution of the responses than the more usual approaches such as comparisons of means, MANOVA or ordinal data methods. The approach transforms the Likert responses into paired comparison responses between the items. The complete multivariate pattern of responses thus produced can be analysed by an appropriately reformulated paired

Abstract:
Dans cette thèse, l’objectif est d’améliorer les capacités prédictives des méthodes hybrides RANS/LES par le développement d’un modèle à l’échelle de sous-filtre qui prend en compte une relation algébrique explicite pour les stresses turbulents de sous-filtre non-isotropes et les flux scalaires turbulents. Tout d'abord, un modèle explicite algébrique (EARSM) est développé et calibré avec le modèle BSL de Menter pour les écoulements incompressibles dans un contexte RANS. Deuxièmement, le modèle EARSM est étendu dans le cadre hybrides RANS/LES. Méthodes hybrides RANS/LES spécifiquement dans le c

Abstract:
Simulations have shown to be one of the best tools to study properties of galactic large scale structures and their effects on to the local kinematics of stars. The aims of this thesis are: i) To obtain realistic N-body models that allow us to analyse kinematics, dynamics and internal structure of non-axisymmetric components in galaxies, ii) to learn how to control numerical effects and also how to distinguish them from the proper physical ones, iii) to find observable parameters from stellar kinematics that can give us information about formation, evolution and nature of the large scale struc

Abstract:
Recent observations have shown that coronal shocks driven by coronal mass ejections can develop and accelerate particles within several solar radii in large solar energetic particle (SEP) events. Motivated by this, we present an SEP acceleration study that including the process in which a fast shock propagates through a streamer-like magnetic field with both closed and open field lines in the low corona region. The acceleration of protons is modeled by numerically solving the Parker transport equation with spatial diffusion both along and across the magnetic field. We show that particles can b

Abstract:
Vision narratives provide important evidence for the social and religious concerns of the society which records them, and are important sources for the mentalité of the period in which they are produced. This thesis provides an historical study of dream and vision narratives from the fourth to eighth centuries, with the hagiographic literature of Gaul and Merovingian Francia as its primary focus. During the period under review, there were important changes in the church's attitude towards the visionary experience. Whereas the fear of heterodoxy led early church Fathers to limit the spiritual

Thesis (PhD)--Stellenbosch University, 2015<br>ENGLISH ABSTRACT : In 2010, young people aged 15–24 years accounted for 42% of new HIV infections globally. In 2009, about five million (10%) of the total South African population was estimated to be aged 15–19 years. Current South African national sero-prevalence data estimate the prevalence of HIV to be 5.6% and 0.7% among adolescent girls and boys aged 15–19 years, respectively. HIV infections are mainly transmitted via sexual transmission. Adolescent sexuality is multi-faceted and influenced at multiple levels. In preparing to enroll adol

Abstract:
Dans le cadre de la simulation à grandes échelles (LES), la thèse aborde la simulation des sprays dans les conditions d’un moteur à injection directe. La vitesse de l’injection des sprays dans ces conditions est très élevée. En conséquence, des structures énergétiques intermittentes aux petites échelles turbulentes peuvent se manifester dans l’écoulement produit. C’est pourquoi l’accent est mis sur la simulation stochastique des effets turbulents aux échelles non-résolues par LES dans les conditions d’un moteur à injection directe.

Cette thèse est une contribution au calcul des variations et à la théorie du contrôle optimal dans les cadres discret, plus généralement time scale, et fractionnaire. Ces deux domaines ont récemment connu un développement considérable dû pour l’un à son application en informatique et pour l’autre à son essor dans des problèmes physiques de diffusion anormale. Que ce soit dans le cadre time scale ou dans le cadre fractionnaire, nos objectifs sont de : a) développer un calcul des variations et étendre quelques résultats classiques (voir plus bas); b) établir un principe du maximum de Pontryagin

Highly evolved, efficient and sophisticated biological systems can be used as models for scientific innovations. This research explored specific surface structures on plant leaves with respect to their hydrophobicity in the context of the often arid Australian climate. The relationships between leaf surface structures and their hydrophobicity could inform the making of artificial surfaces with specially designed hydrophobicity. Moderate hydrophobicity and strong surface adhesion were discovered on many study plant leaves. Scanning Electron Microscopy (SEM) revealed that their surface morpholog

Chez les mammifères, l'ADN des cellules interphasiques s'organise en une fibre chromatinienne confinée à l'intérieur de « territoires chromosomiques ». Ce confinement autorise l'établissement d'interactions à longue distance permettant une régulation fine des fonctions génomiques. Toutefois, l'organisation et la dynamique de la chromatine à l'échelle dite supranucléosomale (10 à 500 kb) reste méconnue. Afin d'étudier la chromatine à cette échelle, nous avons utilisé la méthode dite de 3C-qPCR qui permet de mesurer les fréquences d'interactions entre deux portions génomiques. Dans un premier te
