Die versoenbaarheid van katoen/nylon- en katoen/poliester- skeringgebreide terriestofhanddoeke met industriele versorgingsproseduresDe Bruin, Riette 10 1900 (has links)
Thesis (MVerbruikerswet)--University of Stellenbosch, 2005. / ENGLISH ABSTRACT: The aim of the study was to investigate the compatibility of cotton/nylon and cotton/polyester warpknit
terry towelling fabrics with industrial laundering procedures. The literature review focused, on
the one hand, on the manufacture, finishing and structure of warp-knit terry towelling fabrics as well
as on the physical structure, chemical nature and characteristics of the textile fibres used in the
manufacturing of the towelling. On the other hand, a full exposition of the industrial laundering
processes is provided, with specific reference to aspects that can have an effect on the towelling
fabrics during the wash and tumble-drying cycles.
Chapters Three and Four are reports on two research projects that can each be read
independently. The aim of the first project was to determine the effect of industrial laundering
procedures on the durability of cotton warp-knit terry towelling fabrics with a synthetic base
structure. The tensile strength of cotton warp-knit terry towelling samples with a synthetic base
structure was determined in the warp and weft directions and after 10, 20, 30, 40, and 50 wash
cycles as well as wash and tumble-drying cycles. The tensile strengths in the warp direction of the
washed terry towelling samples decreased significantly (p < 0.001) after 50 wash cycles. In
contrast to this, the tensile strength in the weft direction increased, although not significantly
(p > 0.05). As far as the comparison of the effect of industrial wash and wash and tumble-drying
cycles is concerned, the tensile strengths in the warp direction of the towelling samples that were
washed and washed/tumble-dried, were significantly lower (p < 0.001) after 20 and after 50
laundering cycles. As far as the tensile strengths in the weft direction were concerned, a similar
pattern as with the wash and wash/tumble-drying processes, occurred. The tensile strengths
initially increased and then gradually decreased. Furthermore, the tumble-drying process had
greater damaging effects after 40 laundering cycles (p = 0.043) and especially after 50 laundering
cycles (p < 0.0001).
The aim of the second research project was to compare the durability of cotton warp-knit terry
towelling fabrics with a nylon base structure with cotton warp-knit terry towelling fabrics with a
polyester base structure after they had been subjected to industrial laundering processes. It was
first established whether cotton/nylon and cotton/polyester warp-knit terry towelling fabrics are
comparable. Secondly, the durability of cotton/nylon and cotton/polyester terry towelling fabrics
was compared by determining the tensile strengths of the samples in the warp direction after they
have been subjected to 50 industrial wash as well as wash and tumble-drying cycles. The two
groups of untreated samples were regarded as similar on the basis of the percentage of fibre
composition, knit fabric structure, knit density, mass and tensile strength. After 50 industrial wash
cycles the tensile strengths of the cotton/nylon and cotton/polyester warp-knit terry towelling
samples decreased significantly (p < 0.05). But there was no significant difference (p > 0.05) between the tensile strengths of the cotton/nylon and the cotton/polyester terry towelling samples
after 50 washing cycles. There was a highly significant difference (p < 0.001) between the tensile
strengths of the cotton/nylon and the cotton/polyester terry towelling samples after 50 wash and
tumble-drying cycles. The tensile strength of the cotton/polyester terry towelling samples remained
practically unchanged after the 50 wash/tumble-drying cycles, with the tensile strength of the
cotton/nylon terry towelling samples decreased significantly (p < 0.001). / AFRIKAANSE OPSOMMING: Die doel van die studie was om ondersoek in te stel na die versoenbaarheid van katoen/nylon- en
katoen/poliëster- skeringgebreide terriestofhanddoeke met industriële versorgingsprosedures. In
die literatuuroorsig is daar enersyds gefokus op die vervaardiging, afwerking en struktuur van
skeringgebreide terriehanddoekstowwe asook op die fisiese struktuur, chemiese aard en
eienskappe van die tekstielvesels waarvan die handdoeke vervaardig is. Andersyds is ’n volledige
uiteensetting van industriële versorgingsprosedures gegee, met spesifieke verwysing na aspekte
wat tydens die was- en tuimeldrogingsiklusse ’n uitwerking op die handdoekstowwe kan hê.
Hoofstukke drie en vier is opgeskryf as twee navorsingsprojekte wat elk ‘n geheel vorm. Die doel
van die eerste projek was om die effek van industriële versorgingsprosedures op die
duursaamheid van katoen skeringgebreide terriestofhanddoeke met ‘n sintetiese basisstruktuur te
bepaal. Die breeksterkte van katoen skeringgebreide terriestofmonsters met ’n sintetiese
basisstruktuur is in die skering- en inslagrigtings tydens en na afloop van 10, 20, 30, 40, en 50
was- asook was- en tuimeldrogingsiklusse bepaal. Die breeksterktes in die skeringrigting van die
gewaste terriestofmonsters het betekenisvol afgeneem (p < 0.001) na 50 wassiklusse. In
teenstelling hiermee het die breeksterktes in die inslagrigting toegeneem, hoewel nie betekenisvol
nie (p > 0.05). Wat die vergelyking van die effek van industriële was- en was en
tuimeldrogingsiklusse betref, is die breeksterktes in die skeringrigting van die handdoekmonsters
wat gewas en gewas/getuimeldroog is, beduidend laer (p < 0.001) na 20 en na 50
versorgingsiklusse. Wat die breeksterktes in die inslagrigting betref het ‘n soortgelyke patroon by
die was- en was/tuimeldrogingprosesse voorgekom. Die breeksterktes neem aanvanklik toe en
daarna geleidelik af. Verder het die tuimeldrogingsproses na 40 versorgingsiklusse (p = 0.043) en
veral na 50 versorgingsiklusse (p < 0.0001) ’n groter skadelike effek getoon.
Die doel van die tweede navorsingsprojek was om die duursaamheid van katoen skeringgebreide
terriestowwe met ’n nylon basisstruktuur te vergelyk met katoen skeringgebreide terriestowwe met
’n poliëster basisstruktuur nadat dit aan industriële versorgingsprosedures blootgestel is. Daar is
eerstens vasgestel of katoen/nylon en katoen/poliëster terriehanddoekstowwe vergelykbaar is.
Tweedens is die duursaamheid van katoen/nylon en katoen/poliëster terriestowwe vergelyk deur
die breeksterktes van die monsters in die skeringrigting te bepaal nadat dit aan 50 industriële wasasook
was- en tuimeldrogingsiklusse blootgestel is. Die twee groepe onbehandelde monsters is
as soortgelyk beskou op grond van die persentasie veselsamestelling, breistofstruktuur,
breidigtheid, massa en breeksterkte. Na 50 industriële wassiklusse het die breeksterktes van die
katoen/nylon en katoen/poliëster skeringgebreide terriestofmonsters betekenisvol (p < 0.05)
afgeneem. Daar was egter nie ’n betekenisvolle verskil (p > 0.05) tussen die breeksterktes van die katoen/nylon en katoen/poliëster terriestofmonsters na 50 wassiklusse nie. Daar was ’n hoogs
betekenisvolle verskil (p < 0.001) tussen die breeksterktes van die katoen/nylon en
katoen/poliëster terriestofmonsters na die 50 was/tuimeldrogingsiklusse. Die breeksterkte van die
katoen/poliëster terriestofmonsters het na die 50 was/tuimeldrogingsiklusse feitlik onveranderd
gebly terwyl die breeksterkte van die katoen/nylon terriestofmonsters hoogs betekenisvol
(p < 0.001) afgeneem het.

The development and evaluation of measurements on spaghetti with diverse quality characteristicsMacGregor, Elizabeth 04 1900 (has links)
Thesis (MSc)--University of Stellenbosch, 2005. / ENGLISH ABSTRACT: Pasta manufacturing is a process whereby wheat flour is converted into a shelf-stable food that is
more desirable than native wheat flour. It can be fortified and may serve as a valuable source of
nutrition in developing countries. Quality measures are of importance in the production process to
ensure a consistent and acceptable finished product.
Literature provides information on many aspects of wheat types, milling techniques and processing
of pasta. Protein content and quality of cultivated wheat varieties is of major importance to
produce quality pasta products. Wheat types of lower protein content are more readily available
than traditionally used durum wheat. As in all food products, the cost of final products is of major
importance. Bread wheat is generally less expensive than durum wheat. However, product quality
(and thus acceptability) may be lower. Direct measurements of product quality are currently limited
to protein content, moisture content, colour analyses and certain other characteristics measurable
in a laboratory, for example mechanical strength and firmness. Direct measurements of defects
that may affect final product quality, such as cracks and fissures on the strands of spaghetti,
different types of spots and lines on the strands, broken units, units sticking together and odd
shapes are not well documented.
During the first part of this study, spaghetti quality evaluation techniques were reviewed, improved
or developed and thereafter standardised. This developmental research was conducted to
establish valid and reliable measures (with a high degree of repeatability) for the evaluation of dry
and cooked pasta quality characteristics. A wide variety of available products on the South African
market were evaluated for different quality characteristics. From this evaluation standards were
drawn up, tested for validity and reliability by means of repeatability. Minimum sample sizes for the
evaluation of different quality characteristics were calculated and presented in the study, together
with reference photographs that can be used to evaluate spaghetti. This study found that colour evaluation by means of commercially available apparatus needs
revision. This study suggests the use of multiple layers when evaluating translucent food products
for colour. The occurrence of fissures and flour spots are of importance for the quality of the final
product. This study provides a set of valid and reliable measurements for measuring the quality of
dry and cooked spaghetti. Simple techniques can therefore be used to detect the presence or
absence of these defects.
Thereafter an empirical study was conducted to describe the differences between spaghetti
prepared from durum and non-durum wheat, dried at different temperatures and at different relative
humidity. Spaghetti samples of diverse perceived quality, from different manufacturers, were
purchased and evaluated. Standard methods and the newly developed testing methods were used
to test whether these methods effectively distinguish between spaghetti of diverse quality,
reflecting on the validity of the methods. Correlations were calculated between dependent and
independent variables in an attempt to find possible explanations for certain defects or quality
differences, and to test certain theories in the literature.
Certain relationships between quality characteristics were found, while others were questioned.
The most important proven relationships were between protein content and its effects on reducing
quality defects such as fissures, breakages and cooking losses. The relationship between ash
content and spaghetti colour could not be confirmed in this study. This study confirmed that
protein remains one of the most important variables to ensure consistent quality spaghetti. / AFRIKAANSE OPSOMMING: Pastavervaardiging is ‘n proses waartydens koring meel omskep word in a produk met ‘n stabiele
en lang rakleeftyd wat meer gewens is as die oorspronklike koring meel. Pasta kan gefortifiseer
word and kan dien as a waardevolle voedingsbron in ontwikkelende lande. Om ‘n konstante en
aanvaarbaare finale produk te verseker is kwaliteitmetings gedurende die produksie proses
belangrik.
Die literatuur voorsien heelwat inligting rakende aspekte van belang vir pastakwaliteit, byvoorbeeld
koringtipes, maaltegnieke en die vervaardigingsproses. Proteïninhoud en die kwaliteit daarvan is
van groot belang tydens die produksie van hoë kwaliteit pasta. Koringtipes met ‘n laer
proteïninhoud is meer geredelik beskikbaar as tradisionele durumkoring. Soos met alle
voedselprodukte, is die koste van die finale produk van groot belang. Oor die algemeen verhandel
broodkoring teen laer pryse as durumkoring. Die produkkwaliteit en aanvaarbaarheid van pasta
vervaardig van broodkoring kan egter laer wees as dié van durumkoring. Direkte metings van
produkkwalitiet is tans beperk tot proteïninhoud, voginhoud, kleuranalise en sekere eienskappe
meetbaar in ‘n laboratorium, byvoorbeeld meganiese sterkte en fermheid. Die direkte meting van
defekte wat finale produkkwaliteit kan beïnvloed, byvoorbeeld barste, krake, meel kolletjies, strepe
op spaghetti-eenhede, gebreekte eenhede, eenhede wat aan mekaar kleef en ongewone vorms, is
nie goed gedokumenteer nie.
Gedurende die eerste gedeelte van hierdie studie, is ‘n oorsig van spaghetti evaluasie tegnieke
beskikbaar in die literatuur gdoen, waarna sekeres verbeter is, ander ontwikkel is en finaal
gestandariseer is. Hierdie navorsing is uitgevoer om geldige en betroubare metings (met ‘n hoë
graad van herhaalbaarheid) vir die evaluasie van droë- en gaar pastakwalitietseienskappe vas te
stel. ‘n Wye verskeidenheid van produkte beskikbaar op die Suid-Afrikaanse mark is ge-evalueer
ten opsigte van verskillende kwaliteitseienskappe. Vanuit hierdie evaluasies is standaarde
saamgestel en getoets vir geldigheid en betroubaarheid deur middel van herhaalbaarheid. ‘n
Minimum steekproefgrootte per kwaliteitseienskap is bereken en word vermeld in hierdie studie.
Daarmeesaam word verwysingsfoto’s aangebied wat gebruik kan word tydens die evaluasie van spaghetti. Hierdie studie bied a stel geldige en betroubare meting vir die kwaliteit van droe en
gaan spaghetti. Eenvoudige tegnieke kan dus gebruik word om die voorkoms van hierdie defekte
te meet.
Met afloop van die verkennende studie, is ‘n empiriese studie gedoen om die verskille te beskryf
tussen pasta vervaardig van durum en brood koring, gedroog teen verskillende temperature en
relatiewe humiditeit. Spaghettimonsters met oënskynlike diverse kwaliteit, vervaardig deur
verskillende maatskappye, is aangekoop en ge-evalueer. Standaardmetings en nuutontwerpte
metings is gebruik om te bevestig of die metings kan onderskei tussen spaghetti met
uiteenlopende kwaliteit, wat reflekteer op die geldigheid van die metingsmetodes. Korrelasies is
bereken tussen afhanklike en onafhanklike veranderlikes in ‘n poging om moontlike verklarings vir
sekere defekte of kwaliteitsverskille te vind, en ook om sekere teoriëe in die literatuur te toets.
Die verband tussen sekere kwaliteitseienskappe is bevestig en bewys, terwyl ander bevraagteken
was. Die mees belangrike verband was proteïninhoud en die effek daarvan om die voorkoms van
defekte, soos barste, gebreekte eenhede en kookverliese te verlaag. Die verband tussen
asinhoud en spaghettikleur kon nie in hierdie studie bevestig word nie.
Hierdie studie het bevestig dat proteïn die mees belangrike veranderlike is wat oorweeg moet word
wanneer ‘n konstante hoë kwaliteit spaghettiproduk vervaardig word. Kleurevaluasie met behulp
van kommersieel-beskikbare apparaat vereis hersiening. Hierdie studie stel voor dat tydens kleur
evaluasie van voedsel wat lig deurlaatbaar is, dit in veelvoudige lae evalueer moet word. Die
voorkoms van defekte soos barste, krake of meel kolletjies is van belang ten opsigte van finale
produkkwaliteit. Hierdie studie bied riglyne vir die evaluasie van die genoemde defekte. Die
voorkoms van hierdie defekte is van groter belang as die graad waarteen die defek voorkom.
Eenvoudige tegnieke kan vervolgens gebruik word om die teenwoordigheid of afwesigheid van
hierdie defekte te bepaal.

Meat quality of raw and processed guinea fowl (Numeda meleagris)Tlhong, Tumelo Maud 12 1900 (has links)
Thesis (MSc (Consumer Science)--Stellenbosch University, 2008. / The purpose of this study was to investigate the chemical composition mineral and cholesterol
content of the different cuts (breast, drumstick and thigh) of raw guinea fowl meat. The study
also aimed at establishing the effect of cooking method on guinea fowl quality attributes by
investigating the effect of different cooking methods on the chemical composition and sensory
attributes of the different cuts. The effect of injecting a brine solution on the chemical
composition and sensory attributes were also investigated.
There were no differences in terms of moisture content of the various cuts raw guinea fowl meat
The breast had significantly higher protein content when compared to drumstick and thigh
(P<0.05). The fat content was similar for all the cuts (P>0.05). Whilst the drumstick had
significantly the lowest value for ash content when compared to the thigh. Saturated fatty acids
(SFAs) and total unsaturated fatty acids (TUFAs) were not different (P>0.05) in all the cuts.
Drumstick had significantly higher monounsaturated fatty acids compared to other cuts (P<0.05),
and it had the highest polyunsaturated fatty acids (P<0.05). The breast had the lowest (P<0.05)
n-6 fatty acid value (44.25) and had relatively the lowest Polyunsaturated:Saturated (P:S) fatty
acid ratio of 1.74 when compared to the other cuts. High n-6:n-3 ratios, ranging from 7.05 to
16.58, were also found in all the cuts. Cholesterol was lowest (P<0.05) in the breast. Seventeen
amino acids were found, including the eight of the nine essential amino acids. Significant
differences were found in amino acid values for the different cuts. Values of iron were
significantly higher in the drumstick and thigh cuts (P<0.05), whilst drumstick had the highest
zinc content of all the cuts (P<0.05).
On investigating the effect of three cooking methods (baking-bag, foil-wrap, open-roasting at
140ºC for 65 minutes) on the chemical composition, the open-roasting method produced higher
moisture content (P<0.05) consistently for all cuts, with the breast having the highest and the
drumstick the lowest (P<0.05). The moisture content of the baking-bag method on the other
hand was consistently the lowest (P>0.05). This effect was significant for the breast, which had
lost the most moisture (P<0.05). The baking-bag method consistently resulted in a higher protein
content, which is attributed to the higher moisture loss (P<0.05) in comparison with the other
methods, resulting in a more concentrated product. With regard to the fat content no effect
resulting from the cooking methods could be observed (P>0.05), but the cuts’ natural fat content
was reflected especially in the open–roasting method (P<0.05) giving further support to the understanding that the open-roasting method indeed made the least inroads on the chemical
composition of guinea fowl meat under these restraints: controlled for cooking time and
temperature, internal temperature not controlled.
All the cuts cooked according to all the methods, had the favourable >0.4
Polyunsaturated:Saturated fatty acids (P:S) ratio, ranging from 0.91 to 1.42 between cuts and
treatments. The n-6:n-3 ratio was below the recommended beneficial value, namely <4:1, in all
the cuts irrespective of all the cooking methods, ranging from 2.47 to 3.08.
The study of the effect of the three cooking methods (baking-bag, foil-wrap and open-roast) on
the sensory attributes of the breast meat revealed that aroma-intensity of the three cooking
treatments did not differ significantly (P>0.05). Foil-wrap produced a more tender and juicier
product (P<0.05), while, when using the baking-bag method, values for flavour decreased
(P<0.05). It is proposed that a higher internal temperature (which was not controlled) was
attained when using the baking-bag method (temperature and time controlled) resulting in loss
of volatile flavour components.
The effect of the three cooking methods (baking-bag, foil-wrap and open-roast) on the proximate
composition (moisture, protein, fat and ash) of raw and cooked breast meat was investigated. As
anticipated raw breast meat had higher moisture content (74.55%, P<0.05) than the cooked
cuts, with open-roasting showing the highest (68.55%) value and foil-wrap close second
(68.12%). These values differed significantly from the baking-bag method (66.06%, P<0.05).
An investigation on the effect of brine infusion on the sensory attributes and chemical
composition (proximate and fatty acid composition, and mineral content) of breast meat, baked
in foil-wrap, was carried out using descriptive sensory analysis with the injected breast and the
control as variable. There were no significant differences (P>0.05) between the injected and the
control samples for any of the sensory attributes of aroma, tenderness, initial juiciness,
sustained juiciness and flavour. Judge:treatment variations were observed for all the attributes,
and samples differed for all attributes except for aroma. It is proposed that the use of the hand
injector could not effectively distribute the brine solution, hence the recommendation to repeat
the experiment using an electronic multineedle-injector. No effect was observed for the
proximate composition (P>0.05). Further research pertaining to cooking methods of meat of
free-range guinea fowl is recommended to address certain issues that have been highlighted.

Professional socialisation of family ecology and consumer science students at South African UniversitiesCornelissen, Judith Jean 03 1900 (has links)
Thesis(PhD)--University of Stellenbosch, 2006. / Professional socialisation can be described as a subconscious process whereby persons
internalise behavioural norms and standards and form a sense of identity and commitment
to a professional field. The primary goal of professional socialisation is considered to be
internalisation of the professional culture and the development of a professional identity. It
is learned through interaction with professionals and educators during a student’s
education. It is a continuous, life-long process of learning formal knowledge, skills and
rules, as well as informal and tacit knowledge, norms, values and loyalties within the
profession. An understanding of the professional socialisation process is vital to all persons
involved in postsecondary education, for it is the professional socialisation process that
allows education to achieve its goals.
This dissertation determined whether students of Family Ecology and Consumer Sciences
in South Africa are professionally socialised into developing a professional identity within
the Family Ecology and Consumer Sciences profession. The objectives of the research
included; to examine through a literature review the development of the profession and to
propose a new position for the profession in South Africa; to identify the factors that
influenced South African students when they decided on Family Ecology and Consumer
Science as a field of study and the factors that influenced them while they were obtaining
their degree at a South African university; to determine whether Family Ecology and
Consumer Science students evidence the developmental stages of the Cohen model of the
professional socialisation process; to determine Family Ecology and Consumer Science
professionals’ perceptions of their professional preparation environments; and to analyse
and compare Family Ecology and Consumer Science programmes at South African
universities.
A quantitative research methodology in the form of an analytical survey was undertaken
with the participation of students and staff at South African universities where Family
Ecology and Consumer Science programmes are offered by means of postal questionnaires. Three questionnaires were used in the research, namely; the Professional Socialisation
Influences (PSI) questionnaire; the Professional Socialisation Staging Scale (PS3)
questionnaire; and the Emphases, Process and Influences on the Professional Preparation
Programmes questionnaire. A conceptual framework was used to compare the Family
Ecology and Consumer Science professional preparation programmes presented at South
African universities..
Descriptive statistics and the factor analysis method were used to examine the objectives to
determine which factors influenced students to select Family Ecology and Consumer
Sciences and the factors that influenced them while they were studying for a degree at a
South African university. Descriptive statistics, ANOVA and Bonferroni Post-Hoc tests
were used to examine whether Family Ecology and Consumer Science students evidenced
the developmental stages of the Cohen model of the professional socialisation process.
Descriptive statistics were used to examine Family Ecology and Consumer Science
professionals’ perceptions of their professional preparation environments.
The main findings drawn from the study indicated that Family Ecology and Consumer
Sciences students, when selecting Family Ecology and Consumer Science as a profession,
were influenced by the ‘Service Ideal’ and ‘Entrepreneurial’ factors. Aspects that elicited
the highest percentage of positive responses from the respondents were; ‘desire to help
others’; ‘a desire to improve the quality of family living’; ‘a desire to help people learn to
do things’; and ‘entrepreneurial possibilities of the course’.
While studying for a degree in Family Ecology and Consumer Science, they were
influenced by the factors ‘Student Interaction’ and ‘Departmental Influences’. Aspects such
as; ‘career opportunities available’; ‘application of what I learned to my personal life’; and
‘employment opportunities available’; were those that had the biggest influence.

Development of standardized sizing systems for the South African children’s wear marketVan Huyssteen, S. 04 1900 (has links)
Thesis (DSc (Consumer Science)--University of Stellenbosch, 2006. / 326 leaves on CD format, preliminary i-xix pages and numbered pages 1-210. Includes bibliography, list of tables, figures and appendixes. / ENGLISH ABSTRACT: This research focused on the need of the children’s wear industry in South Africa for sizing systems based on accurate and current body measurement tables developed from the actual measurements of children. The broad objective of this study was to develop standardised measuring methodologies and techniques which would be relevant to the subsequent development of reliable, accurate and comprehensive body measurement tables. These tables could then be implemented as a basis for the development of new sizing systems, as well as new, improved and authentic fit dummy ranges. The literature study served as a point of departure for the planning and execution of the empirical study, focusing on sizing and size designation systems. The study population comprised children representative of three categories, namely age (2 to 14 years), gender (boys and girls) and sector (Black and Non-Black) categories. A convenience sample was selected, representing children from two geographical areas (Western Cape and Gauteng). The empirical study has a three phase structure. The first pilot study aimed at developing standardised measuring equipment, as well as the methodologies and properly recorded guidelines for their implementation. The specific standards according to which subjects were measured and the strict quality control measures implemented to ensure the validity, reliability and accuracy of recorded data, were confirmed during the second pilot study. Based on this, the final study was executed following the guidelines as recorded in the Field Worker Manual. The statistical analysis was done after data capturing during which the data sets were first cleaned up. Secondly, the key measurements for use as a basis for the development of the sizing systems were identified. Based on these, body measurement tables were compiled and age of gender split and growth patterns were analysed for fit dummy prototype development. The new size designation system developed for children’s clothing was successfully implemented as a multi-indicator system, linking height ranges with both age ranges and numerical size indicators. The development of the subsequent new and improved fit dummy prototypes was based on measurements within minimum and maximum values of the body measurements, in order to facilitate the construction of these three-dimensional bodies. It was also possible to develop complete body measurement tables with accurate, and notably irregular, increments between sizes as well as to determine specific growth patterns and separate growth spurts for both boys and girls. This study made new and original as well as more detailed and correct information available concerning the size and shape of the typical South African children’s wear consumer. Using the information contained in the new height based sizing system, retailers have been able to develop a proper set of grade rules for application in product development. The identification and demarcation of important body landmarks facilitated pattern drafting, garment development and fit assessments, resulting in an improved product offering for the typical South African children’s wear consumer. Recommendations regarding further research were formulated, such as comparing the study population categories, namely gender, age and sector. Implications for retailers, inter alia that each retail company could choose how to implement the new height based sizing system and the specific size designation system most suitably for their own consumers and internal systems. The standards set and methodologies implemented in this survey were an improvement on the sizing and fit of children’s wear in the context of South African manufacturers, retailers and consumers. / AFRIKAANSE OPSOMMING: Hierdie navorsing fokus op die behoefte van die Suid-Afrikaanse kinderklerekleinhandelbedryf aan ‘n sisteem van kleregroottes, gebaseer op akkurate en huidige liggaamsmate-tabelle wat ontwikkel is van die werklike mates van kinders. Die oorkoepelende doelstelling van hierdie studie was om gestandaardiseerde meetmetodologieë en -tegnieke te ontwikkel wat relevant is vir die daarstelling van betroubare, akkurate en omvattende liggaamsmate-tabelle, wat dan gebruik kan word as basis vir die nuwe kleregroottesisteem, sowel as om nuwe, verbeterde en oorspronklike figuurmodelreekse te ontwikkel. Die literatuurstudie het gedien as vertrekpunt vir die beplanning en uitvoering van die empiriese studie met die fokus op kleregroottesisteme en kleregrootteaanwysingsisteme. Die kinders in die studiepopulasie het drie kategorieë verteenwoordig: ouderdom (2 tot 14 jaar), geslag (seuns en meisies) en sektor (Swart en Nie-Swart). ‘n Gerieflikheidsteekproef is uit twee geografiese areas (Wes-Kaap en Gauteng) gekies. Die empiriese studie het ‘n drie-fase-struktuur. Die eerste loodsstudie het ten doel gehad om gestandaardiseerde meettoerusting, meetmetodologieë en behoorlik aangetekende implementeringsriglyne daar te stel. Die spesifieke standaarde waarvolgens die proefpersone gemeet is en die implementering van streng kwaliteitbeheermaatreëls wat geldige, betroubare en akkuraat vasgelegde data verseker, is tydens die tweede loodsstudie bevestig. Die finale studie is gebaseer op en uitgevoer volgens die riglyne soos uiteengesit in die Field Worker Manual. Die statistiese analise is gedoen nadat die data vasgelê en skoongemaak is. Vervolgens is sleutelmates geïdentifiseer wat as basis vir die ontwikkeling van kleregroottesisteme kan dien. Volledige liggaamsmate-tabelle is daarna ontwikkel. Die identifisering van die geslagverdelingsouderdom, sowel as die analisering van groeipatrone vir die ontwikkeling van figuurmodelle, is hierop gebaseer. Die nuwe klere-aanwysingsisteme wat ontwikkel is vir kinderklere is suksesvol geïmplementeer as ‘n veelvoudige aanwysingsisteem wat liggaamslengtereekse met ouderdomsreekse en numeriese grootte-aanwysers koppel. Die nuwe en verbeterde figuurmodel-prototipes wat vervolgens ontwikkel is, is gebaseer op minimum en maksimum waardes van die liggaamsmates ten einde die konstruksie van die driedimensionele figure te vergemaklik. Daarbenewens was dit moontlik om volledige liggaamsmate-tabelle met akkurate en opmerklik ongelyke inkremente tussen groottes daar te stel, sowel as om die spesifieke groeipatrone en afsonderlike groeitoenames vir beide seuns en meises te bepaal. Die studie het nuwe en oorspronklike, sowel as meer gedetailleerde en korrekte inligting ten opsigte van die grootte en vorm van die tipiese Suid-Afrikaanse kinderklereverbruiker beskikbaar gestel. Met hierdie nuwe kennis van die liggaamslengte-gebaseerde kleregroottesisteem, is dit nou vir kleinhandelaars moontlik om ‘n volledige stel graderingsreëls daar te stel en in produkontwikkeling toe te pas. Die identifikasie en afbakening van belangrike liggaamsbakens vergemaklik patroon- en klereontwikkeling sowel as die evaluering van die mate waarin dit pas; dit waarborg ‘n verbeterde produk vir die tipiese Suid-Afrikaanse kinderklereverbruiker. Aanbevelings vir verdere navorsing is gemaak, soos ‘n vergelyking van die studiepopulasiekategorieë, naamlik geslag, ouderdom en sektor. Die implikasies vir kleinhandelaars is onder meer dat elke kleinhandelaar kan kies hoe om hierdie nuwe liggaamslengte-gebaseerde kleregroottesisteem te implementer en watter die mees geskikte kleregrootte-aanwysingsisteem vir hul verbruikers en interne sisteme sal wees. Die standaarde wat vir hierdie studie gestel is, sowel as die metodologieë wat geïmplementeer is, is ‘n aansienlike verbetering op die groottes en pas van kinderklere binne die konteks van die Suid-Afrikaanse vervaardigers, kleinhandelaars en verbruikers.

A participatory action research approach to programme evaluation in a rural societyBester, Alte 03 1900 (has links)
Thesis (MA)--University of Stellenbosch, 2002. / ENGLISH ABSTRACT: Recently, Participatory action research (PAR) has become a common approach to
social programmes in South Africa. This tendency has created a need to evaluate
this kind of programmes to determine if it really achieves what it sets out to do. The
purpose of this study was to evaluate an entrepreneurial skills training programme in
a rural community where a participatory action research approach was followed.
A literature review was undertaken to present an in-depth look into the body of
literature that surrounds the study. Programme evaluation was discussed as a
research design, including types and stages of evaluation. The concept of
empowerment was investigated. The review also included a study of literature on
PAR, especially the definitions, context and process of PAR. The role of
entrepreneurship in rural development was also investigated as well as the
evaluation of entrepreneurial skills training programmes.
An entrepreneurial skills training programme was implemented in the rural town of
Darling on the West Coast of South Africa. The PAR approach was followed in the
implementation of the study that was conducted over a period of 15 months.
Participants joined the programme that included different projects, voluntarily. The
participants were divided into three groups according to their period of participation in
the programme. The researcher facilitated actions as well as reflection meetings with
the group of participants before and after the entrepreneurial skills training course.
The researcher made field notes during the implementation of the programme. The
participants' empowerment status was measured with a standardized questionnaire
using a pre-test-post-test design. The participants' application of the entrepreneurial
skills that were taught in the course was measured during semi-structured interviews
at the end of the research perico. four case studies document the extremes of the
respective outcomes of the programme, namely empowerment and entrepreneurship.
Statistical analysis showed statistically significant improvements in the micro, macro
and total empowerment scores of the total group. Looking at the three groups
separately, group one showed statistically significant improvements on the micro and interface levels and group two on the micro level. Even though group three showed
small improvements on all three levels, none of them were statistically significant.
Data from the field notes wer:e analyzed according to the PAR concepts of
participation, action and reflection. Participation mostly had a collaborative nature;
action was aimed at economical change and reflection aimed at practical problem
solving. The interviews revealed that 20 of the 24 participants had micro baking
businesses at the end of the research period and they succeeded in the short-term
goal of applying the skills that were taught in the course. The case studies showed no
correlation between the participants' application of entrepreneurial skills and the
changes in their empowerment status.
The findings of the study suggest that the longer participants participate in a PAR
programme, the bigger the improvement in their empowerment status will be.
Monitoring of the implementation revealed that the study fell short of the "ideal type"
of PAR, since participation was not yet collegiate. Actions were only effective in
economic change and not in social transformation. Reflection resulted in limited
critical self-awareness among the participants. The PAR approach has proven to be
successful in the attainment of the short-term goals of an entrepreneurial skills
training programme. The long-term sustainability of the entrepreneurs' businesses
will have to be followed-up by further research. / AFRIKAANSE OPSOMMING: Die afgelope tyd is deelnemende aksie navorsing (DAN)'n algemene benadering tot
sosiale intervensie programme in Suid-Afrika. Hierdie tendens het 'n behoefte laat
ontstaan om hierdie tipe programme te evalueer om te bepaal of dit werklik die
program doelwitte bereik. Die doel van hierdie studie was om 'n
entrepreneursvaardighede opleidingsprogram in 'n landelike gemeenskap waar die
DAN-benadering gevolg is, te evalueer.
'n Literatuuroorsig is onderneem om die konseptueie raamwerk wat vir die studie
saamgestel is, te kan beredeneer. Programevaluering, insluitende tipes and stadia
van evaluering, is bespreek as 'n navorsingsontwerp. Die konsep van bemagtiging is
ook bestudeer. Die oorsig het 'n ook studie van literatuur oor DAN ingesluit, veral
definisies, die konteks en die proses van DAN. Die rol van entrepreneurskap in
landelike ontwikkeling is 00~ ondersoek sowel as die evaluering van
opleidingsprogramme gemik op die ontwikkeling van entrepreneursvaardighede.
'n Entrepreneursvaardighede opleidingsprogram is in 'n landelike dorpie, Darling, aan
die Weskus van Suid-Afrika geïmplementeer. Oor 'n periode van 15 maande is die
DAN-benadering in die implementering van die program gevolg. Deelnemers het
vrywillig by die program wat uit verskillende projekte bestaan het, aangesluit. Die
deelnemers is na aanleiding van hul tydperk van deelname in die program in drie
groepe verdeel. Die navorser het aksies sowel as refleksie byeenkomste met die
groep deelnemers voor en na die entrepreneursvaardighede opleidingskursus
gefasiliteer. Die navorser het veldnotas tydens die implementering van die program
gemaak. Die deelnemers se bemagtigingstatus is gemeet met 'n gestandaardiseerde
vraelys terwyl 'n voor-en-na-toets ontwerp gevolg is. Die deelnemers se toepassing
van die entrepreneursvaardighede wat in die kursus geleer is, is tydens semigestruktureerde
onderhoude aan die einde van die navorsingsperiode gemeet. Vier
gevallestudies dokumenteer die uiterstes van die onderskeidelike uitkomste van die
program, naamlik bemagtiging en entrepreneurskap. Statistiese analise het statisties betekenisvolle verbeteringe in die mikro, makro en
totale bemagtigingsvlakke van die totale groep getoon. Afsonderlik gesien, het groep
een statisties betekenisvolle verbeteringe op die mikro en tussenvlak getoon en
groep twee net op die mikrovlak. Alhoewel groep drie klein verbeteringe op al drie
vlakke getoon het, was geen van die verbeteringe statisties betekenisvol nie. Data
van die veldnotas is volgens DAN konsepte, naamlik deelname, aksie en refleksie
geanaliseer. Die deelnemers en die fasiliteerder se deelname het meestal In
samewerkende aard gehad, aksie was gemik op ekonomiese verandering en
refleksie was gemik op praktiese probleemoplossinq. Die onderhoude het aangetoon
dat 20 van die 24 deelnemers aan die einde van die navorsingsperiode In mikro
bakbesigheid gehad het en dat hulle daarin geslaag het om die korttermyn doelwit,
naamlik die toepassing van die vaardighede wat in die kursus geleer is, te bereik. Die
gevallestudies het geen korrelasie getoon tussen die deelnemers se toepassing van
entrepreneursvaardighede en die veranderinge in hulle bemagtigingstatus nie.
Die studie se bevindinge dui daarop dat hoe langer deelnemers aan In DAN-program
deelneem, hoe groter sal die verbetering in hulle bemagtigingstatus wees. Die
monitering van die implementering van die program het laat biyk dat die studie tekort
skiet in vergelyking met die "ideaaltipe" van DAN, want die deelname was nog nie
korporatief nie. Aksies was net suksesvol in ekonomiese verandering en nie in
sosiale transformasie nie. Refleksie het tot beperkte kritiese "selfbewustheid" by die
deelnemers gelei. Dit blyk dat die DAN-benadering suksesvol was om die korttermyn
doelwitte van In entrepreneursvaardighede opleidingsprogram te bereik. Die
langtermyn volhoubaarheid van die entrepreneurs se bakbesighede sal met verdere
navorsing opgevolg moet word.

The development of a scale for the measurement of the perceived importance of the dimensions of apparel store imageJanse van Noordwyk, H. S. 03 1900 (has links)
Thesis (PhD (Consumer Science. Clothing and Textiles))--University of Stellenbosch, 2008. / The current apparel retail environment is marked by intense competitive activity. The key to
survival is the implementation of effective differentiation strategies. Corporate and retail
branding provides retailers with a powerful tool to differentiate themselves in the marketplace
and store image is a vital component of this branding strategy. This exploratory study set out
to investigate the underlying theoretical structure of store image. A store image scale was
developed for the measurement of the perceived importance of store image.
The study adopted a five phase methodology, namely (1) construct definition and domain
specification, (2) generation and judging of measurement items, (3) purification of the store
image scale, (4) assessing the reliability and validity of the store image scale, and (5)
assessing the perceived importance of the dimensions of store image in selected discount
and specialty stores through practical implementation of the store image scale. The first two
phases of the study resulted in a Model of Store Image delineating the underlying structure of
store image which formed the basis for a store image definition, as well as a 232-item store
image scale with established content and face validity. Phase 3 comprised two pilot studies
that served to purify the store image scale. The first pilot study concluded in a 214-item scale
that was deemed too lengthy for practical implementation in the apparel retail environment.
The second pilot study resulted in a 55-item store image scale that was deemed acceptable
for practical implementation. Correlation analysis provided support for the shortened version
of the store image scale. The scale was not representative of all the sub dimensions
associated with store image. This was reflected in the Revised Model of Store Image.
Phase 4 employed a mall-intercept research method. The sample population (n=534)
consisted of apparel consumers, both male and female, between the ages of 20 and 60.
They belonged to the black, coloured or white population groups who patronised specific
apparel retail outlets. Trained fieldworkers gathered the data at selected discount and
specialty apparel stores.
Confirmatory factor analysis was performed on the data and results provided support for the
reliability of the store image scale. The Atmosphere, Convenience, Institutional, and
Promotion dimensions exhibited good model fit. The Facilities and Sales personnel
dimensions, as well as the Revised Model of Store Image showed evidence of acceptable
model fit. The Merchandise and Service dimensions demonstrated poor fit. Only the Sales
personnel dimension showed convergent validity. Support was found for marginal convergent
validity of the Atmosphere, Convenience, Facilities, Promotion, and Service dimensions, as
well as the Revised Model of Store Image. The Institutional and Merchandise dimensions did
not exhibit convergent validity. Apart from the Convenience and Service dimensions, discriminant validity for all dimensions was established. Item analysis identified seven scale
items for deletion which could potentially result in better model fit of the individual dimensions
as well as the Revised Model of Store Image. The deletion of these items could contribute to
increased convergent and discriminant validity.
For purposes of Phase 5 the data gathered during Phase 4 was submitted to statistical
analysis. Results indicated that discount and specialty apparel store consumers ranked the
Atmosphere, Promotion, Merchandise, Institutional, and Sales personnel dimensions similarly
in perceived importance. Discount apparel store consumers ranked the Facilities and
Convenience dimensions higher, whilst specialty consumers ranked the Service dimension
higher. However, the differences in ranking for all dimensions remained relatively small for
both store types. Statistical differences in the perceived importance of only two dimensions,
namely the Institutional and Service dimensions were found.
The study culminated in revised 48-item store image scale. A Final Model of Store Image and
definition of store image were proposed as point of departure for future research.. The main
implications for retailers were formulated as:
The Final Model of Store Image identified the dimensions and sub dimensions of store
image. Retailers should manipulate the tangible and intangible store attributes
associated with these dimensions and sub dimensions to build a favourable store image.
Due to the gestalt nature of store image it is imperative that all store image dimensions
are presented in a cohesive and consistent manner.
The store image scale will enable retailers to ascertain which dimensions are salient to
their target consumers. These dimensions should be incorporated in the retail strategy.

'n Intervensieprogram vir bevordering van inkomstegenerering in 'n landelike gemeenskapsentrumLangenhoven, Magdalena C. (Magdalena Cornelia) 12 1900 (has links)
Thesis (MVerbruikerswet)--University of Stellenbosch, 2004. / ENGLISH ABSTRACT: Rural areas in South Africa experience extreme levels of unemployment, and
therefore are in dire need for skills training. In some rural areas this training takes
place in community centres. Participants are empowered to generate an income.
The activities mostly take place in a group context. In such a community centre a
lack of the presentation of structured skills training programmes was identified. The
aim of the study is to develop a skills training programme to help rural people in
starting an income-generating project in a group context by means of intervention.
In the literature study the concept of community centres was discussed. The basic
human needs and the needs for training were related to the concept of group work.
Programme development for adult education, income-generation and interventions
were described in detail. The development of creativity, empowerment, capacity
building and sustainable development were briefly discussed as potential outcomes
of skills training programmes for the generation of income.
For the purpose of this study a case study was undertaken of existing needlework
groups in the Darling Focus Community Centre. A study group of 15 members was
identified. The duration of the study group's involvement in needlework training was
determined. The need for skills training workshops and the study group's interest in
group work were established.
Although the activities of the study group take place in group context, very little
evidence exist of co-operation towards the objective of income generation. A major
shortcoming is the failure to pinpoint objectives in the group. Darling is a rural tourist
attraction with a target market for the sale of handcrafted products. For this purpose
the crafted products need to adhere to certain criteria. Despite the opportunity to
market products to tourists, only the local market is being targeted. The
requirements of these clients are not considered a priority in the manufacturing of
products. Therefore the study group was considered a suitable case study in this
research. An intervention programme was compiled and implemented in group
context for the training of skills in the manufacturing, marketing and selling of
products.
Surveys were done by self-administered questionnaires and unstructured interviews
were conducted with important role players. Workshops were presented where skills application was monitored through control lists. The application of business skills
was established through a semi-structured interview. Throughout the process the
researcher made observations and documented information.
Surveys indicated that the duration of the group members' involvement with
needlework activities were between three and eleven years. A clear need for skills
training as well as interest in group work was established and addressed. Self
diagnoses of needs for skills training was done during visits to trade areas. A
brainstorming session was conducted to generate ideas for the manufacturing of
products to be sold. The skills in making these products were demonstrated during
the workshops and practised during follow-up work sessions. A basic business skill
workshop was conducted. After implementation of the intervention the results of the
group work were evaluated at the hand of success criteria identified from literature.
This list of criteria provides a guideline for similar training programmes. / AFRIKAANSE OPSOMMING: Landelike gebiede in Suid-Afrika gaan gebuk onder werkloosheid wat
vaardigheidsopleiding noodsaak. Sommige plattelandse dorpe het gemeenskapsentrums
wat onder meer vaardigheidsopleiding bied. Deelnemers aan die opleiding
word bemagtig om 'n inkomste te kan genereer. Die aktiwiteite vind meestal in
groepverband plaas. 'n Leemte, geïdentifiseer in so 'n gemeenskapsentrum, is die
aanbieding van gestruktureerde vaardigheidsopleidingsprogramme in groepverband
wat mense in staat stel om 'n volhoubare inkomste te genereer. Die studie het ten
doel om deur intervensie 'n vaardigheidsopleidings-program te ontwikkel wat
landelike mense help om 'n inkomstegenereringsprojek in groepverband te vestig.
In die literatuuroorsig is die konsep van gemeenskapsentrums bespreek. Die
basiese menslike behoeftes en behoeftes aan opleiding is in verband gebring met die
konsep van groepwerk. Programontwikkeling vir volwassene-onderwys is uiteengesit
en inkomstegenerering en –intervensies is volledig bespreek. Die ontwikkeling van
kreatiwiteit, bemagtiging, kapasiteitsbou en volhoubare ontwikkeling is kortliks
aangeraak as moontlike uitkomste van vaardigheidsopleidingsprogramme vir die
generering van inkomste.
Vir die doel van hierdie studie is 'n gevallestudie gedoen van bestaande
naaldwerkgroepe gesetel in die Darling Fokus Gemeenskapsentrum. ‘n Studiegroep
van 15 lede is geïdentifiseer. Die tydperk wat die studiegroep by naaldwerkopleiding
betrokke is, is bepaal asook die behoefte aan vaardigheidsopleidingswerkswinkels.
Verder is die studiegroep se belangstelling in groepwerk bepaal.
Hoewel die aktiwiteite van die studiegroep in groepverband plaasvind, is daar min
bewyse van samewerking ten einde die doel van inkomstegenerering te bereik. 'n
Groot leemte is dat doelstellings nooit deur die groep gestel was nie. Darling is 'n
landelike toeriste-aantreklikheid met 'n teikenmark vir die verkoop van
handwerkprodukte. Hiervoor moet produkte aan sekere vereistes voldoen. Ondanks
hierdie geleentheid om produkte onder toeriste te bemark, word daar slegs op die
plaaslike mark gemik. Die vereistes van hierdie kliënte is nie 'n prioriteit in die
vervaardiging van produkte nie. Die studiegroep is daarom as 'n geskikte geval
beskou vir hierdie studie. 'n Intervensieprogram is in groepverband vir die opleiding
van vaardighede in die vervaardiging, bemarking en verkope van produkte
saamgestel en geïmplementeer. Opnames is gedoen deur selfgeadministreerde vraelyste en ongestruktureerde
onderhoude is met belangrike rolspelers gevoer. Werkswinkels is aangebied
waartydens vaardigheidstoepassing deur middel van kontrolelyste gemoniteer is.
Die toepassing van besigheidsvaardighede is deur 'n semi-gestruktureerde
onderhoud bepaal. Die navorser het deurentyd die waarneming gedoen en inligting
gedokumenteer.
Opnames het aangedui dat die groeplede tussen drie en elf jaar by die
naaldwerkaktiwiteite betrokke is. 'n Duidelike behoefte aan vaardigheidsopleiding
asook belangstelling in groepwerk is gevind en aangespreek. Selfdiagnose van
behoeftes aan vaardigheidsopleiding is tydens besoeke aan afsetgebiede gedoen. 'n
Dinkskrum is gehou om idees te genereer vir die maak van produkte om te verkoop.
Die vaardighede vir die maak van hierdie produkte is deur middel van werkswinkels
gedemonstreer en in opvolgende werksessies deur die studiegroep ingeoefen. 'n
Besigheidsvaardigheidswerkswinkel waar basiese beginsels behandel is, is
aangebied. Die resultate van groepwerk na die implementering van die intervensie is
aan die hand van sukseskriteria wat uit literatuur geïdentifiseer is, geëvalueer.
Hierdie stel kriteria bied 'n riglyn vir soortgelyke opleidingsprogramme.

Post-occupancy evaluation of state-subsidised housing units in Kayamandi, StellenboschDarkwa, Irene 03 1900 (has links)
Thesis (MSc (Consumer Science)--University of Stellenbosch, 2006. / The South African government drafted a national housing policy in 1994. This policy is being implemented in terms of seven strategies. One of the housing strategies is to provide subsidy assistance to low-income groups to enable them to become home owners and improve their quality of life. The delivery of state-subsidised housing will help to reduce the housing backlog and to reach the goal of eradicating informal settlements by 2014. The purpose of this study was to determine the levels of housing satisfaction of residents in state-subsidised housing units.
