Full textENGLISH ABSTRACT: Qualitative and quantitative research implies different meta-theoretical approaches to knowledge production. The former maintains a constructivist and interpretative perspective, as opposed to the latter, which exists within a realist and even positivist paradigm. Within the field of research methodology, the dominant conceptualisation of validity is based on a positivist discourse, which suggests that (social) scientific research should strive to attain an ultimate truth. This understanding of validity is difficult to achieve within a research paradigm that values the idiosyncratic world views of the participants under investigation. The introduction of CAQDAS (Computer Assisted Qualitative Data Analysis Software), however, brought with it the hope that its application would confer upon qualitative research the rigour associated with validity in a mainly positivist interpretation of the research process. The ultimate goal of this thesis is to determine whether CAQDAS can make a significant contribution to efforts aimed at validating qualitative research. The research design employed in the present study is that of a descriptive content analysis, focussing on scientific articles that not only report qualitative studies, but also make explicit reference to the use of CAQDAS, and describe validation techniques applied during the research process. Purposive sampling was applied to select 108 articles, published from 1996 to 2009, that meet the sampling criteria and that were identified through online searches of various bibliographic databases and search engines. The study investigates three predominant research questions concerned with the following: (1) the most commonly used software programmes; (2) trends in CAQDAS use over time; as well as (3) the validation techniques reported in examined scientific articles, distinguishing between techniques that are performed with and without the use of CAQDAS. With regard to the first two research questions, it was found that the three most commonly used software programmes are QSR N programmes (including NUD.IST, NVivo, N4, N5 and N6), followed by Atlas.ti and MAXqda (including the earlier version winMAX), and that there has been a general increase over iv the past 13 years (1996-2009) in the number of qualitative research articles reporting CAQDAS use. The exploration of validation techniques utilised in qualitative research, as reported in the examined scientific articles, demonstrated that the techniques are in most cases performed manually. Although CAQDAS offers many benefits, the predominant validation techniques reported can be, and still are, performed without CAQDAS. Techniques that would have been impossible without CAQDAS are based on the data display features of CAQDAS, as well as on the accuracy and consistency offered by CAQDAS in the execution of certain actions. The findings generated by this study seem to support the hypothesis that CAQDAS per se does not enhance validity, since it is predominantly utilised as merely a research tool.
AFRIKAANSE OPSOMMING: Kwalitatiewe en kwantitatiewe navorsing is gegrond op verskillende meta-teoretiese benaderings tot die lewering van inligting. Eersgenoemde handhaaf ‘n konstruktivistiese en interpretatiewe perspektief, teenoor laasgenoemde, wat binne ‘n paradigma bestaan wat gegrond is op realisme en positivisme. Binne die veld van navorsingsmetodologie, is die oorwegende konseptualisering van geldigheid, gebaseer op ‘n positivistiese diskoers, wat voorstel dat (sosiale) wetenskaplike navorsing daarna moet streef om ‘n absolute waarheid te bereik. Hierdie begrip van geldigheid word moeilik verwesenlik binne ‘n navorsingsparadigma wat waarde heg aan die ideosinkratiese wêreldbeskouinge van die navorsingsdeelnemers. CAQDAS (Computer Assisted Qualitative Data Analysis Software), is bekend gestel met die hoop dat die gebruik daarvan kwalitatiewe navorsing sal verleen met stiptheid wat met geldigheid geassosieer word, oorwegend binne ‘n positivistiese interpretasie van die navorsingsproses. Die oorkoepelende doelwit van hierdie tesis is om vas te stel of CAQDAS enige betekenisvolle bydrae kan maak tot pogings om die geldigheid van kwalitatiewe navorsing te verbeter. Die navorsingsontwerp van die huidige studie is die van ‘n beskrywende inhoudsanalise, wat fokus op wetenskaplike artikels wat nie net berig oor kwalitatiwe studies nie, maar ook verwys na die gebruik van CAQDAS, en die geldigheidstegnieke wat tydens die navorsingsproses toegepas is, bespreek. Doelgerigte steekproeftrekking is toegepas en 108 artikels, wat gepubliseer is vanaf 1996-2009, was geselekteer op grond van die feit dat hulle aan die seleksie kriteria voldoen. Die artikels was geïdentifiseer deur aanlyn soektogte van verskeie bibliografiese databasisse en soekenjins. Die studie ondersoek drie oorwegende navorsingsvrae met betrekking tot die volgende: (1) die sagteware programme wat die meeste gebruik word; (2) neigings in die gebruik van CAQDAS oor verloop van ‘n tydperk; sowel as (3) die geldigheidstegnieke wat in die ondersoekte wetenskaplike artikels vi gerapporteer word, deur onderskeid te tref tussen tegnieke wat met of sonder die gebruik van CAQDAS uitgevoer word. Met verwysing na die eerste twee navorsingsvrae, was dit gevind dat die drie algemeenste sagteware programme wat gebruik is, QSR N programme (insluitend NUD.IST, NVivo, N4, N5 en N6), gevolg deur Atlas.ti en MAXqda (insluitend die vroëere weergawe winMAX) is, en dat daar oor die algemeen ‘n toename is in die getal kwalitatiewe navorsingsartikels oor die afgelope 13 jaar (1996-2009), wat die gebruik van CAQDAS rapporteer. Die ondersoek na geldigheidstegnieke wat in kwalitatiewe navorsing gebruik word, soos berig in die ondersoekte wetenskaplike artikels, het getoon dat die tegnieke in die meeste gevalle sonder die gebruik van CAQDAS uitgevoer is. Ten spyte van die feit dat die gebruik van CAQDAS voordele inhou, word die meerderheid geldigheidstegnieke wat gerapporteeer word, steeds sonder die gebruik van CAQDAS uitgevoer. Tegnieke wat nie sonder die hulp van CAQDAS uitegevoer kon word nie, is gebaseer op die data vertoningsvermoë van CAQDAS, sowel as op die akkuraatheid en konsekwentheid waarmee CAQDAS sekere opdragte uitvoer. Die bevindinge wat gegenereer is deur hierdie studie blyk asof dit die hipotese ondersteun dat CAQDAS nie opsig self die geldigheid versterk nie, aangesien dit oorwegend bloot as ‘n navorsingsinstrument gebruik word.

Full textThe object-oriented community is paying increasing attention to techniques for object instance encapsulation and alias protection. Formal techniques for modular verification of programs at the level of objects are being developed hand in hand with type systems and static analysis techniques for restricting the structure of runtime object graphs. Ownership type systems have provided a sound basis for such structural restrictions by being able to statically represent an extensible object ownership hierarchy. However, such structural restrictions may potentially have limitations on cases when more flexible reference structures are desired. In this thesis, we present a different encapsulation technique, called Effect Encapsulation, which confines side effects rather than object references. With relaxed restriction on reference structure, it is able to express certain common object-oriented patterns which cannot be expressed in Ownership Types. From this basis, we also describe a model of Object Validity --- a framework for reasoning about object invariants. Such a framework can track the effect and dependency of method calls on object invariants within an ownership-based type system, even in the presence of re-entrant calls. Moreover, we present an access control technique for protecting object instances. Combined with context variance, the resulting type system allows for a more flexible and useful access control policy, hence is capable of expressing more object-oriented patterns.

Full textThe purpose of the present study was to gather further external validity evidence towards the validity argument for an instrument designed to measure individual and contextual factors associated with adolescent substance use in low socio-economic status communities in the Western Cape, South Africa. The South African Substance Use Contextual Risk Instrument (SASUCRI) measures adolescents' subjective experiences of their own psycho-social and their communities' functioning. The present study uses secondary data analysis in order to further evaluate its external validity. Both content and structural evidence for the instrument has been gathered in the larger study in which the present study is located. Validity theory was used as the theoretical framework for the gathering of the different types of evidence in support of the validity argument for this instrument. The study employed non-probability purposive sampling to select schools from three education districts from which twenty-six schools were selected where the sample total was N=1959. English and Afrikaans versions of the instrument were administered to English- and Afrikaans home language, school-going adolescents, aged 12 to 21 years. All ethical standards were maintained throughout the research process. External evidence procedures were conducted using Discriminant Function Analysis (DFA) to evaluate the extent to which the instrument could discriminate between substance using and non-using adolescents. The DFA revealed that nine SASUCRI sub-scales totals can act as significant predictors to substance use among adolescents based on the predictive validity of sub-scales.

Prognostic scores, and more specifically comorbidity scores, are important and widely used measures in the health care field and in health services research. A comorbidity is an existing disease an individual has in addition to a primary condition of interest, such as cancer. A comorbidity score is a summary score that can be created from these individual comorbidities for prognostic purposes, as well as for confounding adjustment. Despite their widespread use, the properties of and conditions under which comorbidity scores are valid dimension reduction tools in statistical models is largely unknown. This dissertation explores the use of summary comorbidity measures in statistical models. Three particular aspects are examined. First, it is shown that, under standard conditions, the predictive ability of these summary comorbidity measures remains as accurate as the individual comorbidities in regression models, which can include factors such as treatment variables and additional covariates. However, these results are only true when no interaction exists between the individual comorbidities and any additional covariate. The use of summary comorbidity measures in the presence of such interactions leads to biased results. Second, it is shown that these measures are also valid in the causal inference framework through confounding adjustment in estimating treatment effects. Lastly, we introduce a time dependent extension of summary comorbidity scores. This time dependent score can account for changes in patients' health over time and is shown to be a more accurate predictor of patient outcomes. A data example using breast cancer data from the SEER Medicare Database is used throughout this dissertation to illustrate the application of these results to the health care field.

Full textThe probabilistic approach to reasoning hypothesizes that most reasoning, both in everyday life and in science, takes place in contexts of uncertainty. The central deductive concepts of classical logic, consistency and validity, can be generalised to cover uncertain degrees of belief. Binary consistency can be generalised to coherence, where the probability judgments for two statements are coherent if and only if they respect the axioms of probability theory. Binary validity can be generalised to probabilistic validity (p-validity), where an inference is p-valid if and only if the uncertainty of its conclusion cannot be coherently greater than the sum of the uncertainties of its premises. But the fact that this generalisation is possible in formal logic does not imply that people will use deduction in a probabilistic way. The role of deduction in reasoning from uncertain premises was investigated across ten experiments and 23 inferences of differing complexity. The results provide evidence that coherence and p-validity are not just abstract formalisms, but that people follow the normative constraints set by them in their reasoning. It made no qualitative difference whether the premises were certain or uncertain, but certainty could be interpreted as the endpoint of a common scale for degrees of belief. The findings are evidence for the descriptive adequacy of coherence and p-validity as computational level principles for reasoning. They have implications for the interpretation of past findings on the roles of deduction and degrees of belief. And they offer a perspective for generating new research hypotheses in the interface between deductive and inductive reasoning

Full textAffinity 2.5 is a computer-based instrument designed to assess sexual interest using viewing-time measures. Viewing-time measures of sexual interest have been developed to identify individuals with deviant sexual interest. The purpose of this study is to examine the validity of Affinity 2.5 in screening and diagnosing individuals with sexually deviant interests. This study used viewing time profiles of known sexual offenders compared to norm-referenced profiles of an exclusively heterosexual, non-pedophilic college population. Participants were 155 males and 3 females who had sexually offended against children and 63 male and 84 female non-offender college students. Results show that 43.7% of offenders were correctly identified as having significantly deviant sexual interest, compared to the reference group. Further 12.0% of offenders showed statistical significant interest in at least one category of individuals from a protected population and offended against that same category. The results of this study do not provide support for the utility of the Affinity 2.5 as a screening or diagnostic tool.
