This thesis is comprised of four studies and concerns haemodialysis patients’ confidence in being able to manage fluid intake between treatment sessions, and whether the fluid intake is influenced by certain modifiable characteristics of the persons in question. The overall aim was to study aspects of excessive fluid overload and haemodialysis patients’ self-regulation of fluid allotment from a bio-psychosocial and behavioural medicine perspective. The extent of non-adherence to fluid allotment was described in Study I. National registry data were used. Three out of ten Swedish haemodialysis patients had excessive fluid overload and one out of five was at risk for treatment related complications due to too rapid ultrafiltration rate. The objective in Study II was to develop and psychometrically evaluate a self-administered scale to measure situation-specific self-efficacy to low fluid intake. The measure (the Fluid Intake Appraisal Inventory) was found to be reliable and valid in haemodialysis settings. Subgroups based on individual profiles of self-efficacy, attentional style and depressive symptoms were explored in Study III using a cluster analytic approach. Three distinct subgroups were found and the subgroup structure was validated for clinical relevance. The individuals’ profile concerning self-efficacy, attentional style and depressive symptoms has to be taken into account in nursing interventions designed to reduce haemodialysis patients’ fluid intake. In Study IV, an intervention designed to reduce haemodialysis patients’ fluid intake was introduced and its acceptability, feasibility and efficacy were evaluated and discussed. Acceptability of such an intervention was confirmed. Addressing beliefs, behaviours, emotions and physical feelings is clinically feasible and may reduce haemodialysis patient’s excessive fluid overload. This thesis indicates that there is a potential for improvement in the fluid management care of haemodialysis patients. Behavioural nursing strategies that aim to assist patients to achieve fluid control should be applied more extensively. Cognitive profiles of the patients should be taken into account when targeted nursing intervention aiming to encourage and maintain the patient’s fluid control is introduced.

I examined the effectiveness of child-centered play therapy (CCPT) and person-centered teacher consultation (PCTC) for elementary school children identified with clinical or borderline levels of ADHD behaviors on the Teacher Report Form and the Conners' Teacher Rating Scale Revised - Short Form. Additionally, I examined the impact of CCPT and PCTC on the levels of parenting and teaching stress. Due to the current trend to determine interventions that are evidence-based through between-group or single case designs, for this study, I utilized a single case design experiment for which the behaviors of five children were examined. Trained observers utilized the Direct Observation Form in observations of all five students three times per week. Additionally, parents and teachers completed behavioral rating scales and stress inventories at pre-, mid-, and post-intervention. To prevent biased observational ratings, observers were blind to the assignment of the five children. Three students participated in 24 sessions of twice-weekly 30-minute sessions of CCPT, and these students' teachers participated in six sessions of once-weekly 10-minute PCTC. Two students participated in twice-weekly 30-minute sessions of reading mentoring, after which they participated in 14 sessions of CCPT. Visual analysis of the data indicated mixed results. Three students demonstrated substantial improvement in the observed ADHD behaviors within the classroom. Results of the parent and teacher assessment data were inconsistent, but did indicate behavior change for some children and a reduction in teaching stress for one teacher. Parenting stress appeared unaffected. Implications for future research regarding the use of single case design, the measurement of student behavior change, and issues of comorbidity are indicated.

Abstract in English, Zulu and Afrikaans / The primary intent of this study was to develop a competitive intelligence (CI) programme implementation strategy framework for the effective use of CI in strategic decision-making (SDM) in a conglomerate, using embedded multiple units and a single-case exploratory study that is qualitative dominant. The study therefore explored the strategic value of CI for SDM in a company that has a conglomerate structure and whose subsidiaries are vertically integrated. Despite the perceived usefulness of CI for distinctive SDM, the case conglomerate and its subsidiaries had collected and employed the available CI products to support their strategic, tactical and other business decisions. Overall results indicated differences between the subsidiaries and the headquarter; and among the subsidiaries on CI practice (CI collection, CI coordination, CI sharing and CI effort) and CI usage for SDM and other decisions. Although a similar strategy development process (guided by the grand corporate strategy), management structure, decision-making process and orientation in the subsidiaries existed, these uniformities did not significantly result in a uniform level of application and usage of CI for SDM across the conglomerate. The conclusion is that CI application is very subjective and contextual even in a vertically integrated conglomerate. Through theory, literature review and empirical findings, synthesis and iteration, a middle-range theory that integrates the CI and SDM disciplines in terms of the contextual issues both share is also constructed. The study also developed a novel way of crafting CI for SDM, which may fit into the existing structure and realities of the conglomerate so as to formalise CI. The CI programme implementation strategy framework was developed considering the proof of tested theories, best practices, existing context, strategy, decision-making process, structure, enabling factors and capabilities of the conglomerate. The CI programme implementation strategy framework, accompanied by a proposed CI structure, has immediate pragmatic utility. It could enable the conglomerate to initiate a formal CI programme without delay and to develop it following an organisational maturation cycle. The study makes an original contribution by conceptualising a CI programme implementation strategy for a unique case and theorising the case within a novel extension within middle-range theory (“SDM and CI application can be viewed in the contextual domains both share”). The exploratory study itself, which led to merging theory and best practices with empirical results and fitting the theories and best practices into case conglomerate’s realities, also makes the study unique in terms of its approach and outputs. / Inhloso enkulu yalolu cwaningo kwakungukusungula uhlaka lokuqala ukusebenzisa uhlelo lwamasu obuhlakani bokuqhathanisa izinkampani ezincintisanayo, obaziwa ngokuthi yiCompetitive Intelligence (iCI) ngesiNgisi ukuze isebenze kahle ekuthathweni kwezinqumo ezihambisana namasu okwaziwa ngestrategic decision-making (iSDM) ngesiNgisi kwinhlanganyela yezinkampani, kusetshenziswa uhlobo locwaningo olungamayunithi amaningi afakwe ndawonye, oluhlola udaba olulodwa nolugxile kakhulu ekuqoqweni kwemininingwane. Ngakhoke, lolu cwaningo luhlole umthelela omuhle wamasu eCI ngokuthatha izinqumo ezihambisana namasu (iSDM) enkampanini enomumo wenhlanganyela yezinkampani enezinkampani ezingena ngaphansi kwayo ezenza imisebenzi eyahlukahlukene. Phezu kokumsebenzi obonakalayo weCI ngokuhlukile kwiSDM, inhlangayela yezinkampani okuyiyo ebhekiwe kanye nezinkampani ezingaphansi kwayo yaqoqa yase isebenzisa imikhiqizo yeCI etholakalayo ukusingatha ukuthatha kwayo izinqumo ezihambisana namasu, namaqhinga kanye nezinye izinqumo zebhizinisi. Imiphumela ephelele yabonisa ukuthi kukhona ukungafani phakathi kwezinkampani ezingena ngaphansi kwayo kanye nekomkhulu; kanti futhi phakathi wezinkampani ezingena ngaphansi kwayo kokuphathelene neCI (Ukuqoqwa kwemininingwane yeCI, ukuhlanganiswa kwemininingwane yeCI, ukusabalalisa imininingwane yeCI nokusebenza kweCI) nokusetshenziswa kweSDM nezinye izinqumo. Nakuba kwakukhona inqubo yokuthuthukisa isu elifanayo (elandela imigomo yesu elihle lenkampani), ukwakheka kohlaka lwabaphethe, inqubo yokuthatha izinqumo kanye nokuqondiswa kwezinkampani ezingaphansi kwenye, lokhu kwefaniswa akuzange kube ngokufanayo endleleni yokwenza nokusebenziswa kweCI kwiSDM kwinhlangayela yezinkampani. Isiphetho ukuthi uhlelo lokusebenza lweCI luncike kakhulu ohlangothini nasengqikithini eyodwa kwinhlanganyela yezinkampani ezenza izinto ezahlukahlukene. Ngokulandela ukuhlaziywa kwemibhalo yemibono yezinzululwazi, kanye nokutholakele uma kwenziwa ucwaningo olubheka izinto ngenkathi zenzeka, ukuhlanganiswa kwemininingwane kanye nokuphindaphindwa kokuhlolwa, kuphinde kwakhiwe imibono yezinzululwazi emibili ehlanganisa imikhakha yeCI neSDM maqondana nezingqikithi ezifanayo kuyona. Ekugcineni, ucwaningo luphinde lwasungula indlela engakaze ibe khona yokwakha iCI iyakhela iSDM engangena ithi khaxa ekwakhekeni nasesimweni esikhona senhlanganyela yezinkampani ukuze iCI ihleleke ngokusemthethweni. Uhlaka lwesu lokuqaliswa kokusebenza kohlelo lweCI lwenziwa ngoba kucatshangwa ngobufakazi obutholakala kwimibono yezinzululwazi ehloliwe, okusebenze ngempumelelo, indikimba ekhona njengamanje, isu, inqubo yokuthatha izinqumo, ukwakheka, yilokho okwenza izinto zenzeke futhi kusebenzeke kwinhlanganyela yezinkampani. Uhlaka lwesu lokuqaliswa kokusebenza kohlelo lweCI, oluphelezelwa ukwakheka okuhlongoziwe kweCI kukwazi ukuhlolisisa kahle umqondo wokukwazi ukubona ubungako bolwazi nesidingo solunye ucwaningo. Kungasiza inhlanganyela yezinkampani, cishe, ukuba ikwazi ukuqala uhlelo olusha lweCI nokulithuthukisa kulandela uchungechunge lwendlela yokukhula yenhlangano. Ucwaningo lufaka ulwazi olusha esivivaneni ngokuqhamuka nomqondo omusha wesu lokuqala ukusebenzisa uhlelo lweCI odabeni olungajwayelekile, bese lubeka imibono ngodaba olubhekwayo ngendlela engakaze yenzeke nehlanganisa imibono yezinzululwazi kanye nocwaningo olubheka izinto ngenkathi zenzeka (“Ukusetshenziswa kweSDM neCI kungabhekwa ezizindeni zengqikithi ezifanayo kukona”). Ucwaningo oluhlolayo, lona uqobo, oluholela ekuhlanganisweni kwemibono yezinzululwazi nokubhekwa kwalokho okucwaningwayo ukuthi kusebenza kahle kuphi kanye nemiphumela yocwaningo olubheka izinto ngenkathi zenzeka, nokuhlanganisa lokho nokwenzeka ngempela enhlanganyeleni yezinkampani, nakho kwenza lolu cwaningo lube ngolwehlukile maqondana nendlela oluyilandelayo kanye nemiphumela evelayo. / Die primêre doel van hierdie studie was om 'n strategieraamwerk vir programimplementering van mededingingsintelligensie (MI) te ontwikkel vir die doeltreffende gebruik van MI in strategiese besluitneming in 'n konglomeraat, deur 'n vasgelegde veelvoudige eenhede, enkelgeval-verkenningstudie, wat ook kwalitatief dominant is, te gebruik. Die studie het dus die strategiese waarde van MI vir strategiese besluitneming verken in 'n maatskappy wat 'n konglomeraatstruktuur het en wie se filiale vertikaal geïntegreer is. Ondanks die waargenome nuttigheid van MI vir spesifiek strategiese besluitneming, het die gevallestudiekonglomeraat en sy filiale die beskikbare MI-produkte versamel en aangewend om hul strategiese, taktiese en ander sakebesluite te ondersteun. Algehele resultate het die bestaan van verskille tussen die filiale en die hoofkantoor aangedui; en tussen die filiale oor MI-praktyke (MI-versameling, MI-koördinering; MI-deling en MI-pogings) en MI-gebruik vir strategiese en ander besluite. Alhoewel daar soortgelyke strategiese ontwikkelingsprosesse bestaan (gelei deur die groot korporatiewe strategie), het hierdie eenvormigheid in bestuurstrukture, besluitnemingprosesse en oriëntering in die filiale nie 'n beduidende eenvormige vlak van toepassing en gebruik van MI vir strategiese besluitneming regdeur die konglomeraat tot gevolg gehad nie. Gevolglik is MI-toepassing baie subjektief en kontekstueel, selfs in 'n konglomeraat wat vertikaal geïntegreer is. Deur teoretiese, literatuuroorsig- en empiriese bevindinge is sintese en iterasie, twee middelvlakteorieë, ook saamgestel wat velde van MI en strategiese besluitneming met betrekking tot die kontekstuele kwessies wat albei deel, geïntegreer het. Op die ou end het die studie ook 'n nuwe manier ontwikkel om MI vir strategiese besluitneming te bewerk wat by die bestaande struktuur en realiteite van die konglomeraat kan inpas om MI te formaliseer. Die strategieraamwerk vir programimplementering van MI is ontwikkel met die bewys van getoetste teorieë, beste praktyke, bestaande konteks, strategie, besluitnemingsproses, faktore wat strukture moontlik maak en vermoë van die konglomeraat, in gedagte. Die strategieraamwerk vir programimplementering van MI, saam met die voorgestelde MI-strukture, het onmiddellike pragmatiese nut. Dit kan die konglomeraat onmiddellik in staat te stel om 'n formele MI-program te inisieer en dit te ontwikkel deur 'n organisatoriese verouderingsiklus te volg. Die studie maak 'n oorspronklike bydra deur 'n strategie vir programimplementering van MI te konseptualiseer vir 'n unieke geval, die teoretisering van die geval binne 'n nuwe uitbreiding in 'n middelvlakteorie ("Toepassing van strategiese besluitneming en MI kan in die kontekstuele domeine beskou word wat beide deel"). Die verkenningstudie self, wat tot die samesmelting van teorie en beste praktyke met die empiriese resultate gelei het en die passing van die teorieë en beste praktyke in die gevallestudiekonglomeraat se realiteite, maak die studie ook uniek met betrekking tot sy benadering en opbrengs. / Graduate School for Business Leadership / D.B.L.
