Examining the equivalence of the PIRLS 2016 released texts in South Africa across three languagesRoux, Karen January 2020 (has links)
The Progress in International Reading Literacy Study (PIRLS) is a large-scale reading comprehension assessment, which assesses Grade 4 learners’ reading literacy achievement. The findings from the last cycle of PIRLS 2016 indicated that South African Grade 4 and 5 learners performed poorly in reading comprehension. This finding confirms the previous cycles’ results where South African learners achieved the lowest results across the participating countries. Approximately eight out of ten Grade 4 learners cannot read for meaning in any of the tested languages. Due to the poor results in PIRLS, the President of South Africa stated that every ten-year old child should be able to read for meaning, thus cementing reading literacy as a national aim. The aim of this mixed methods research was to determine whether the PIRLS Literacy 2016 and PIRLS 2016 limited release texts are equivalent across languages, specifically English, Afrikaans and isiZulu.
Four research sub-questions were explored to assist in addressing the main research question posed by this study: To what extent are the PIRLS 2016 released texts in English, Afrikaans and isiZulu, in Grade 4 and Grade 5 equivalent? As this study took the form of a sequential explanatory mixed methods approach, the first phase investigated the South African Grade 4 and 5 results by firstly looking at descriptive statistics, such as percentages and means. After the initial exploration of the data, I conducted Rasch analyses to determine whether the items from the limited release texts showed measurement invariance – in other words, whether the items behaved differently for different groups of learners. As part of the Rasch analyses, individual item-fit statistics and differential item functioning (DIF) were conducted using RUMM2030. In phase two, the limited release texts were analysed by experts who attended workshops and completed open-ended questionnaires regarding the equivalence of the identified texts. The qualitative phase was conducted in order to complement and extend on the quantitative findings of phase one.
The findings revealed that the limited release texts, with their accompanying items, were not equivalent across the different languages. However, by looking at the items that displayed DIF, there is not a clear pattern as the items did not universally favour one language nor did the texts discriminate universally against a particular language. An in-depth look at the texts and items themselves revealed that the Flowers on the Roof text is considered the poorest translation into Afrikaans and isiZulu. Overall, all the texts were considered to be appropriate for South African learners as the texts made use of rich vocabulary and introduced the learners to new ideas and concepts. Thus, this study offers new insights into the equivalence of the PIRLS assessments as well as possible reasons for the non-equivalence for each of the limited release texts. Based on the findings of this study, recommendations and further research are provided. / Thesis (PhD)--University of Pretoria, 2020. / Science, Mathematics and Technology Education / PhD / Unrestricted

Bezekvivalentní terminologie v právních textech a strategie překladu / Legal Terminology with Null Equivalence: Translation StrategiesŠTĚPÁNKOVÁ, Kristýna January 2018 (has links)
This Master's thesis is focused on zero equivalence in legal texts. The theoretical part deals with technical text and legal language in general. Legal Spanish is characterized and compared to the legal Czech. Translation of the legal language is described along with some obstacles that may be associated with it. At the end of the theoretical part, there are several findings summarized, and the methodology for the practical part is delineated. In the practical part the reader is acquainted with the concept of equivalence and functional equivalence. Equivalence is divided into absolute, partial, and zero equivalence. The following chapters are concerned with the translation of the terminology with zero equivalence, specifically translation methods, strategies and stages. Furthermore, several legal terms are selected and evaluated on the basis of their equivalence. The terms are searched in order to discover their occurrences and counterparts in dictionaries, legal text databases and parallel corpus. Moreover, their possible translation is proposed and applied translation strategies named. The aim of the thesis is to define legal terminology with zero equivalence and provide the classification of the translational strategies that are frequently applied in translation of this kind of lexicon.

Translation of Bird Literature: A Translation Study Focusing on the Translation of Attributive Adjectives and Bird TerminologyRydström, Johannes January 2010 (has links)
<p>This study investigates how best to solve difficulties that may arise when translating bird literature from English into Swedish. The focus of the study lies on the translation of attributive adjectives and bird terminology. The text chosen for the translation, which serves as the basis for the analysis, is the section on general habits of the <em>Turdidae-family </em>in the comprehensive work <em>Handbook of the Birds of the World. </em>Translation theory that proved helpful in the translation process and in the subsequent analysis was primarily that of Vinay and Darbelnet (1995, 2004), Nida (1964a) and Newmark (1981). In most cases a literal translation could be perfonned, both in regard to attributive adjectives and bird tenninology, however, in some cases other translation procedures, such as transposition and equivalence, proved useful. Attributive adjectives that could not be translated literally, or that were preferred not to be translated literally, were translated through the use of transposition, into for instance: compound nouns, prepositional phrases, relative clauses and <em>that-clauses. </em>Bird terminology for which no suitable corresponding terminology could be found in the target language, was translated non-literally through the use of equivalence, into structures maintaining the equivalent semantic meaning in a natural way.</p>

A psychometric evaluation of the Job Demands-Resources Scale in South Africa / Madelyn StrydomStrydom, Madelyn January 2005 (has links)
Although different occupations/organisations have unique work characteristics, it seems
possible to divide them into two categories, namely job demands and job resources. A valid,
equivalent and reliable instrument is needed to measure job demands and resources and to
compare them among different occupations/organisations. The aim of this study was to
investigate the construct equivalence, validity and reliability of a measuring instrument of job
demands and resources and to assess the differences between the job demands and job
resources in various occupations/organisations in South Africa.
A cross-sectional survey design was used. A stratified random sample (N = 2717) was taken
from a population consisting of employees in various occupations and organisations. The
occupations/organisations included academics (higher education institutions), staff at a
university of technology, correctional officers. insurance staff and engineers. The Job
Demands-Resources Scale (JDRS) was used to assess job demands and job resources in the
different occupations/organisations. Descriptive statistics, exploratory factor analysis,
reliability analysis and multivariate analysis of variance were used to analyse the data.
Five reliable factors were extracted using principal component analysis, namely: overload,
growth opportunities, organisational support, advancement and job insecurity. The results
showed that the structure of job demands and job resources in the different
occupations/organisations were equivalent. with the exception of one factor, namely
organisational support.
Engineers showed higher scores on overload and growth opportunities than
Occupations/organisations. Academics in higher education institutions also experienced more
growth opportunities than other groups. Engineers, academics in higher education institutions
and employees in the insurance industry reported higher levels of organisational support than
correctional officers and employees at a university of technology. Engineers obtained the
highest score on advancement, while academics in higher education institutions obtained the
lowest scores. Job insecurity was the highest for correctional officers and employees of a
university of technology, and the lowest for engineers.
Recommendations for future research were made. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2006.

The psychometric properties of the COPE in selected occupations in South Africa / J.H.C. BezuidenhoutBezuidenhout, Johannes Hendrik Coenraad January 2006 (has links)
Coping strategies represent the efforts, both behavioural and cognitive, that people invest in
order to deal with stressful encounters. Coping is a basic component for developing
adaptation and plays a major role in the relationship between the individual and the
environment, especially as a moderating element between stress and sickness. Against this
backdrop of the impact that the well-being of employees has on organisations, it is of the
essence that organisations need to understand how their members cope with the demands
which the organisation places on them. This understanding can assist organisations to
evaluate the resources they make available to help employees to cope more positively with
the demands placed upon them.
The general objective of this study was to investigate the psychometric properties of the
Coping Orientations to the Problems Experienced Questionnaire (COPE) within different
occupational groups in South Africa, to examine the construct equivalence and to assess
reliability. A swey design was used. Random samples (N = 3178) were taken from
electricity supply personnel, nurses and police officials, and the COPE was administered.
Descriptive statistics, exploratory factor analysis and multivariate analysis of variance
(MANOVA) were used to analyse the data.
Exploratory factor analysis, using principal axis factoring with varimax rotation, was
conducted on 53 items of the COPE and revealed four interpretable factors (Factor 1 =
Approach Coping; Factor 2 = Avoidance; Factor 3 = Seeking Support; and Factor 4 = Turn to
Religion). Highly acceptable Tucker's phi coefficients were found for all the comparisons,
and therefore, sufficient evidence for the construct equivalence of the COPE was
demonstrated. Alpha coefficients, ranging from 0,85 to 0,92, were obtained. Statistically
significant differences were found between the coping strategies employed within the
different organisational, gender and language groups.
Recommendations for future research were made. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2007.

Fate of nitrogen/trace metals species during combustion and gasification of biomassPetrolati, Andrea January 2010 (has links)
This thesis focused on the fate of nitrogen and trace metals species from combustion and gasification of biomass. The effect of process parameters on the release of these species during pilot-scale combustion and gasification of biomass was investigated and the information used to identify methods for the reduction of these species. The investigation focused on Miscanthus and Dried distillers’ grains with solubles (DDGS). The pilot-scale test rigs used were a fluidised-bed combustor and a fixed-bed downdraft gasifier. The two fuels were analysed by means of proximate, ultimate and ash analysis. The process parameters monitored were temperatures, gas flow, gas composition and ash composition and the process parameters studied are bed temperature and equivalence ratio. The different nitrogen content of the two fuels plays an important role in the emission. Both bed temperature and air to fuel ratio have demonstrated to have an important influence in the release of nitrogen oxides in combustion and ammonia in gasification, therefore they can be used to mitigate the emission of these species in the flue gas. Both processes are affected by the high alkali metals content of the fuels for the tendency to form low melting composites. Differences have been highlighted in the metal distribution between combustion and gasification. The different nitrogen and ash content of the two fuels make the results of the present thesis applicable to predict the behaviour of other biomass fuels according to the fuel characteristics. The scale of the tests performed allowed highlighting which methods can be used to control the emission of nitrogen and trace metal species. Moreover, the investigation highlighted major drawbacks in the use of biomass fuels in both fluidised bed and fixed bed technology due to ash properties.

A generalisation of pre-logical predicates and its applicationsKatsumata, Shin-ya January 2005 (has links)
This thesis proposes a generalisation of pre-logical predicates to simply typed formal systems and their categorical models. We analyse the three elements involved in pre-logical predicates -- syntax, semantics and predicates -- within a categorical framework for typed binding syntax and semantics. We then formulate generalised pre-logical predicates and show two distinguishing properties: a) equivalence with the basic lemma and b) closure of binary pre-logical relations under relational composition. To test the adequacy of this generalisation, we derive pre-logical predicates for various calculi and their categorical models including variations of lambda calculi and non-lambda calculi such as many-sorted algebras as well as first-order logic. We then apply generalised pre-logical predicates to characterising behavioural equivalence. Examples of constructive data refinement of typed formal systems are shown, where behavioural equivalence plays a crucial role in achieving data abstraction.

The Study of Translation Equivalence on Integer LatticesBoykin, Charles Martin 08 1900 (has links)
This paper is a contribution to the study of countable Borel equivalence relations on standard Borel spaces. We concentrate here on the study of the nature of translation equivalence. We study these known hyperfinite spaces in order to gain insight into the approach necessary to classify certain variables as either being hyperfinite or not. In Chapter 1, we will give the basic definitions and examples of spaces used in this work. The general construction of marker sets is developed in this work. These marker sets are used to develop several invariant tilings of the equivalence classes of specific variables . Some properties that are equivalent to hyperfiniteness in the certain space are also developed. Lastly, we will give the new result that there is a continuous injective embedding from certain defined variables.

Visual acuity of driversKatsou, Maria Foteini January 2014 (has links)
Purpose: In May 2012 UK visual standards for driving changed, in order to comply with European laws. Drivers need to have both a visual acuity of 6/12 AND be able to read a number plate at 20 metres. Previously the number plate test was the only visual acuity test. Methods: Four different distance visual acuity charts were used (Snellen, logMAR letter-similar to ETDRS, logMAR Landolt ring, distance reading acuity- similar to MNRead chart) and were presented at 6m. 120 drivers were tested binocularly without refractive correction. Participants were taken outside to perform the number plate test at 20m. A second study was conducted, with 38 participants whose vision was impaired to approximately 6/12 using simulation spectacles. Results: Differences between the visual acuities as measured by the charts were statistically but not clinically significant. For all charts there is an overlap zone within which participants may pass only one of the two tests, outside this range, participants pass or fail both tests. The 6/12 cut-off provides reasonable sensitivity and specificity for Snellen and logMAR letter charts. A poorer acuity cut-off was needed with the Landolt chart to maximize the relationship with the number plate test. Conclusions: The 6/12 visual cut-off and the number plate test will not always pass or fail the same drivers. Snellen and logMAR letter charts are recommended to be used to measure the visual acuity of drivers, but not Landolt rings. Fifteen percent of the sample could read a number plate at 20m, but was not able to achieve either 6/12 or +0.30 logMAR. The overlap zone is a helpful tool to identify those people who need advice from Eye Care Practitioners.
