An investigation into the quality of interaction in early childhood education in Ghana : a constructivist perspectiveOppong Frimpong, Samuel January 2017 (has links)
This mixed methods research is an investigation into the quality of interaction in the provision of Early Childhood Education (ECE) in Ghana. Literature suggests that a reasonable number of ECE teachers from developing countries, including Ghana, lack training and content knowledge in ECE. In addition, there is a general lack of Teaching and Learning Materials (TLMs), play equipment and ECE facilities. Constructivism, a theoretical position which postulates that children create knowledge through their interaction with the environment in which they find themselves, was adopted as the theoretical framework for this study. Data in the form of interviews, observation and questionnaires were collected from 131 participants. These comprised 104 teachers and 23 headteachers, selected from 24 schools in the Greater Accra region of Ghana. Also, four ECE coordinators were interviewed as part of the data collection. The findings from this study suggest that a large proportion of teachers in the study were not appropriately trained. There was a variation with teachers in the remote areas most underequipped. The pedagogical strategies the sampled teachers adopted were found to be what could be described as teacher-dominated which potentially hindered the quality of the interaction with their learners and in their lesson delivery. Based on these findings, it is suggested that teachers endeavour to train in ECE methodologies and also re-orient their pedagogical practices to align with child-centred approaches. This may enable them to interact appropriately and involve their learners in their lesson delivery. Additionally, given the circumstances (e.g. limited TLMs and play items) some of the teachers find themselves in their schools, it is recommended that teachers should encourage their learners to effectively use what the natural environment would afford them.

High accuracy numerical model of the SALT mirror support trussDe Lange, Billy 12 1900 (has links)
Thesis (MScEng)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: Although a numerical model of the mirror support truss of the Southern
African Large Telescope (SALT) has already been developed during the design
thereof, this thesis focuses on the development of the methods and techniques
that would result in a more accurate numerical model of the actual structure
that could be used as a basis for a numerical control system. This control
system will compensate for de ections in the structure by adjusting the positioning
of the individual mirror segments of the primary mirror.
The two main components from which the support truss is constructed
are the steel nodes, and the struts that connect to them. For this project a
smaller, simpler laboratory model was designed and built to have geometrical
properties similar to that of the support truss. The methods and techniques
that were investigated were carried out on this model.
By using numerical design optimisation techniques, improved numerical
models of the different strut types were obtained. This was done by performing
tests on the struts so that the actual responses of the struts could be
obtained. Numerical models of the struts were then created and set up so that
they could be optimised using structural optimisation software. Once accurate
strut models had been obtained, these strut models were used to construct a
numerical model of the assembled structure. No additional optimisation was
performed on the assembled structure and tests were done on the physical
structure to obtain its responses. These served as validation criteria for the
numerical models of the struts.
Because of unforeseen deformations of the structure, not all of the measured
structural responses could be used. The remaining results showed, however, that the predictive accuracy of the top node displacement of the assembled
structure improved to below 1.5%, from over 60%. From these results it was
concluded that the accuracy of the entire structure's numerical model could
be signi ficantly improved by optimising the individual strut types. / AFRIKAANSE OPSOMMING: Alhoewel daar reeds 'n numeriese model van die spieëlondersteuningsraamwerk
van SALT ontwikkel is gedurende die ontwerp daarvan, fokus hierdie tesis
op die ontwikkeling van metodes en tegnieke om 'n numeriese model van steeds
hoër gehalte van hierdie spesi eke struktuur te verkry wat kan gebruik word as
'n basis vir 'n numeriese beheerstelsel. Hierdie beheerstelsel sal kan kompenseer
vir die ondersteuningsraamwerk se vervormings deur om die individuele
spieëlsegmente van die primêre spieël se posisionering te verstel.
Hierdie stuktuur bestaan uit hoofsaaklik twee komponente, naamlik staalnodusse
en die stutte wat aan hulle koppel. Vir hierdie projek is 'n kleiner,
eenvoudiger laboratorium-model ontwerp en gebou om geometriese eienskappe
soortgelyk aan die van die ondersteuningstruktuur te hê. Die metodes en tegnieke
wat ondersoek is, is op hierdie model uitgevoer.
Verbeterde numeriese modelle van die verskillende stut-tipes is ontwikkel
deur middel van numerieseoptimeringstegnieke. Dit is gedoen deur toetse op
die stutte uit te voer sodat hul werklike gedrag bepaal kon word. Numeriese
modelle van die stutte is toe geskep en opgestel sodat hulle geoptimeer kon
word om dieselfde gedrag as wat gemeet is, te toon. Hierdie geoptimeerde
modelle is toe gebruik om numeriese modelle van die toets-struktuur te skep.
Geen verdere optimering is op die numeriese model uitgevoer nie en toetse is
op die struktuur gedoen om sy werklike gedrag te meet. Data wat deur die
toetse verkry is het as validasie kriteria gedien om die akkuraatheid van die
numeriese modelle van die stut-tipes te bepaal. Weens die struktuur se onvoorsiene vervorming kon alle gemete struktuurdata
nie gebruik word nie. Die oorblywende data het egter getoon dat die
akkuraatheid van die finale numeriese modelle van die struktuur verbeter het
en dat dit die translasie van die top-node met 'n speling van 1.5% akkuraatheid
kon voorspel, teenoor die oorsponlike speling van meer as 60%. Daar is bevind
dat die akkuraatheid van die numeriese model van die hele struktuur noemenswaardig
verbeter kan word deur die numeriese modelle van die stut-tipes te
optimeer.

The construal of romantic relationships in transgendered people : a personal construct approachZarroug, Amani January 2012 (has links)
National Health Service (NHS) statistics show that 4000 people in the United Kingdom are receiving help for gender concerns (DH, 2008). Research has highlighted the importance of romantic relationships during early adulthood and an association with mental health (Fincham and Cui, 2011). The experience of romantic relationships among transgender people in ‘emerging adulthood’ (Arnett, 2000, 2006) is an under-researched area. The decision making process concerning, and construal of, romantic relationships among this group have yet to be investigated using Personal Construct Theory (PCT). This study uses qualitative and quantitative methods of inquiry from PCT to investigate the experiences of transgender people encountering romantic relationships. Overarching themes emerging from the participants in this study were of identity validation through romantic relationships, having a bi-gendered lens of the world, facilitating greater understanding in society, and learning from past relationships. Participants’ experiences are analysed individually, as well as as a group. Clinical significance of this, limitations and future research are also discussed.

Influence of ground motion scaling methods on the computed seismically-induced sliding displacements of slopesWang, Yubing 14 February 2011 (has links)
Evaluation of the seismic stability of slopes often involves an estimate of the expected sliding displacements. This evaluation requires a suite of acceleration-time histories as input motions. The methods of selecting and scaling these motions can affect the computed sliding displacements. Linear scaling of recorded ground motions and modification of recorded motions by spectral matching are common approaches used for ground motion selection and these approaches were used in this study to select motions for use in sliding displacement analyses. Rigid sliding block analyses and decoupled flexible sliding block analyses were performed using a suite of linearly scaled motions and a suite of spectrally matched motions. . Generally, the spectrally matched motions predict 10 to 30%, on average, smaller displacements and significantly less variability than the linearly scaled motions, when both suites of input motions were developed to match the same acceleration response spectrum. When both suites of input motions were developed to match the same peak ground velocity and acceleration response spectrum, the spectrally matched motions generally predict 5 to 15%, on average, larger displacements than the linearly scaled motions. Because ground motion parameters beyond acceleration response spectrum affect the computed sliding displacement, parameters such as peak ground acceleration (PGA), peak ground velocity (PGV) and mean period (T[subscript m]) should be considered in selecting and scaling motions for use in sliding displacement analyses. / text

Habitat linkages and highway mitigation using spatially-explicit GIS-based modelsJones, Andrew Charles 13 December 2012 (has links)
I identified suitable locations for highway wildlife crossing mitigations across the TransCanada Highway (TCH) in the area of Mount Revelstoke and Glacier National Park (MRGNP), British Columbia. Highways fragment natural landscapes leading to habitat loss, reduced ecosystem connectivity and direct wildlife mortality though motor vehicle collisions. Grizzly bears (Ursus arctos) are vulnerable to the effects of habitat and population fragmentation. Highway wildlife crossing mitigations improve ecosystem connectivity by increasing the permeability of transportation corridors to wildlife. I identified high-quality habitat patches using a resource selection function (RSF) based on 1,703 radio telemetry locations from 59 grizzly bears. Least-cost path analysis (LCP) among habitat patches identified 6 linkage zones across the TCH. Electric circuit theory was used to generate current maps that classify linkage zones as high-volume crossing areas or tenuous linkages. Linkage zones occurred where high-quality habitat aligned with physical features conducive to cross-valley wildlife dispersal.

Clustering algorithms and their effect on edge preservation in image compressionNdebele, Nothando Elizabeth January 2009 (has links)
Image compression aims to reduce the amount of data that is stored or transmitted for images. One technique that may be used to this end is vector quantization. Vectors may be used to represent images. Vector quantization reduces the number of vectors required for an image by representing a cluster of similar vectors by one typical vector that is part of a set of vectors referred to as the code book. For compression, for each image vector, only the closest codebook vector is stored or transmitted. For reconstruction, the image vectors are again replaced by the the closest codebook vectors. Hence vector quantization is a lossy compression technique and the quality of the reconstructed image depends strongly on the quality of the codebook. The design of the codebook is therefore an important part of the process. In this thesis we examine three clustering algorithms which can be used for codebook design in image compression: c-means (CM), fuzzy c-means (FCM) and learning vector quantization (LVQ). We give a description of these algorithms and their application to codebook design. Edges are an important part of the visual information contained in an image. It is essential therefore to use codebooks which allow an accurate representation of the edges. One of the shortcomings of using vector quantization is poor edge representation. We therefore carry out experiments using these algorithms to compare their edge preserving qualities. We also investigate the combination of these algorithms with classified vector quantization (CVQ) and the replication method (RM). Both these methods have been suggested as methods for improving edge representation. We use a cross validation approach to estimate the mean squared error to measure the performance of each of the algorithms and the edge preserving methods. The results reflect that the edges are less accurately represented than the non - edge areas when using CM, FCM and LVQ. The advantage of using CVQ is that the time taken for code book design is reduced particularly for CM and FCM. RM is found to be effective where the codebook is trained using a set that has larger proportions of edges than the test set.
