This thesis examines the media strategies employed by leading figures and organizations in the Russian political opposition landscape, namely Alexei Navalny's Anti-Corruption Foundation (ACF), Dmitry Gudkov's Secretariat of European Russians, Mikhail Khodorkovsky's Russian Action Committee, Feminist Anti-War Resistance, and Ilya Ponomarev. Using critical discourse analysis as its core methodology, the study aims to unravel the complex dynamics between stated values and media strategies. The strategies analyzed include 'Investigative Outreach,' 'Diaspora Engagement,' 'Media Magnate Mobilisation,' 'Grassroots Guerrilla Artivism,' and 'Dual Role Diplomacy.' The study is framed within the theoretical constructs of social constructivism and media frame theory. These frameworks allow for a critical examination of how the media strategies of these entities are socially constructed and framed, thereby shaping public perception and narrative. Key findings reveal that although these strategies amplify political reach and influence, they also pose challenges such as dilution of core messages and ethical quandaries.

Donor-acceptor systems exhibit distinctive attributes rendering them highly promising for the emulation of natural photosynthesis and the efficient capture of solar energy. This dissertation is primarily devoted to the investigation of these unique features within diverse donor-acceptor system typologies, encompassing categories such as closely covalently linked, push-pull, supramolecular, and multi-modular donor- acceptor conjugates. The research encompasses an examination of photosynthetic analogs involving compounds such as chelated azadipyromethene (AzaBODIPY), N,N-dimethylaminophenyl (NND), phenothiazine (PTZ), triphenylamine (TPA), phenothiazine sulfone (PTZSO2), tetracyanobutadiene (TCBD), and expanded tetracyanobutadiene (exTCBD). The strategic configuration of the donor (D), acceptor (A), and spacer elements within these constructs serves to promote intramolecular charge transfer (ICT), which are crucial for efficient charge and electron transfer. The employment of cutting-edge analytical techniques, such as ultrafast transient absorption spectroscopy, is integral to the study. Furthermore, a comprehensive suite of analytical methodologies including steady-state UV-visible absorption spectroscopy, fluorescence and phosphorescence spectroscopies, electrochemical techniques (including cyclic voltammetry and differential pulse voltammetry), spectroelectrochemistry, and density functional theory calculation (DFT), collectively contribute to the comprehensive characterization of push-pull donor-acceptor systems, with a particular emphasis on their potential as highly effective solar energy harvesting application.

Every citizen has the right to be equipped with scientific literacy to understand and make informed decisions within the discipline of science. Educators can utilize core science teaching practices (CSTPs) to develop scientific literacy. In response, this study identified the CSTPs utilized by preservice elementary teachers (PSETs) to develop scientific literacy during their spring 2022 student teaching semester. Furthermore, this study identified contextual constructs that led to the utilization of the CSTPs to develop scientific literacy. The study used a qualitative exploratory case study using semi-structured interviews as the primary data. Surveys and artifacts were used as supporting secondary data. The identification of CSTPs and their contextual constructs were conducted using inductive content analysis. Afterward, the identified CSTPs and their contextual constructs were deconstructed, interpreted, and synthesized through the critical theoretical framework of disciplinary literacy. Relationships, time, school structure, and community were contextual constructs that enabled and disabled PSETs' utilization of CSTPs to develop scientific literacy. The contextual constructs are represented using the Framework to Develop Scientific Literacy (FDSL). The FDSL contain contextual constructs that enabled PSETs to utilize CSTPs through the sharing of power between the PSET and their cooperating teacher, school district, community, or teacher education programs. In contrast, contextual constructs that disabled PSETs include denying of power that negatively impacted the utilization of CSTPs to develop scientific literacy. The findings of the study call for teacher education programs to include contextual constructs as elements that impact PSETs' student teaching experiences to navigate power dynamics in authentic school settings. By identifying and using constructs as represented in the FDSL, teacher education programs can support PSETs' utilization of CSTPs to develop scientific literacy. In addition, this study calls for a reframing of power relationships between teacher education programs and their partnering school districts. By revealing the complex contextual nature of the PSETs' student teaching experiences, this study seeks to initiate discussion on how teacher education programs can support the practice of PSETs as they educate the next generation of scientifically literate citizens.

This study investigates transformational leadership at a higher education institution. The systems paradigm serves as the point of departure, while the construct `leadership', which forms the driving force of change in the organisation, and the concept `transformational leadership', are integrated to yield a mechanism for the optimal positioning of the organisation in the ambit of transformation. The results indicate that the leadership style at the higher institution in question is transformational in nature. From the literature review it became evident that although it is possible for transformational leaders to fail in the transformational strategy, the transformational leader may exhibit the most `ideal' leadership style for the higher education institution engaged in a turnaround strategy. Based on the results of the study, additional proposals are made regarding further study in the area of transformational leadership as well as possible decisions regarding human resource management for the higher education institution in question. / Industrial and Organisational Psychology / M.A. (Industrial and Organisational Psychology)

Leadership is a problematic topic at universities and it is therefore difficult to isolate a leadership theory that is applicable to Heads of Department (HODs). The manner in which HODs construe their leadership roles is the focus of this research project and the study is conducted from a constructivist perspective The university context in which HODs lead is explored in the literature overview. Definitions of leadership, general leadership theories and leadership issues in academe are investigated. The research findings are integrated into a leadership model for HODs, consisting of constructs (leadership behaviours, actions and values) and elements (leadership situations). The following contributions are made by the study: * The variety roles an HOD has to fulfil is confirmed by the study. However, this study indicates that leadership is interwoven with everything an HOD undertakes. * HODs construct their roles uniquely, but in general terms most HODs consider academic and scholarly work (own and that of the department) as part of the leadership role they fulfil. Leadership at HOD level at university incorporates both managerial and leadership ideas. * HODs consider their leadership environment to have qualities of the following known university environments: collegial, enterprise, bureaucratic and corporate. * This study identifies eight leadership themes with reference to the leadership role of an HOD at university; providing academic guidance, being a figurehead, determining the strategy and positioning the department, liaising with internal and external stakeholders, being a change agent, being a general manager, and being involved in student and staff relations. The following leadership themes can be added to the current body of literature: being a figurehead, own scholarly profile, as well as being involved in staff and student relations. Leadership at academic departments is at the heart of everything in which an HOD is involved. Leadership is thus becoming indispensable at academic departments at university. / Industrial & Organisational Psychology) / D. Com. (Consulting Psychology)

The Living Standards Measure (LSM), a South African marketing segmentation method, is a wealth measure based on standard of living. This research study investigates whether a rationale can be found for the inclusion of value-related variables in this type of multivariate segmentation approach. Schwartz’s (1992; 2006) values model was used to operationalise personal values and individual-level culture – focusing on two of its dimensions, ideocentrism and allocentrism. The current positive psychology research trend manifests in the inclusion of subjective wellbeing (SWB), as measured by satisfaction with life (SWL). The primary objective of this research was to investigate at individual (and not group or societal) level whether values and SWL can be used to discriminate among multivariate consumer segments. Data were collected by means of a survey from a nationally representative sample (n = 2566) of purchase decision-makers (PDMs). The measurement instruments used were the Portrait Values Questionnaire (PVQ) and the Satisfaction with Life Scale (SWLS). A multi-group confirmatory factor analysis (MGCFA) was used to assess the psychometric properties and test the equivalence of the scales across cultural groups. MGCFA was also used to test for differences across LSM groups on the PVQ and SWLS. Centred value scores were used to test for differences between LSM groups in terms of their values and SWL, using MANOVA. The findings supported Schwartz’s theory of basic human values, and small differences were found in the PVQ values between LSM groups using the MGCFA approach. MANOVA analyses showed stronger differences across LSM groups. PDMs in the higher LSM segments were more satisfied with their lives. No significant relationships between values and SWL were found, and the effect of individual-level culture, as a higher-order dimension of four values, showed a small but significant effect on SWL. / Psychology / D.

This study focused on multilingualism as the primary linguistic cognitive objective of investigation. An integrative approach focused on second language linguistics in order to acquire a background in the cognitive foundations of language and research methodology and theoretical models for the study of phenomena, such as language planning in multicultural societies and language and ethnic diversity. To design cognitive reading methods, a literature survey was conducted regarding the latest developments in the theories pertaining to cognitive formulas of the second language learner. A quantitative experimental study was conducted, data gathered was scrutinised and a cognitive reading programme was experimentally administered to twenty primary school learners. The responses were coded, the data captured and statistically computed. Conclusions indicated that cognitive reading materials were practical, valid and reliable. Cognitive formulas hold the potential of contributing to the understanding of cognitive reading development in second language proficiency in the Foundation Phase of schooling. / Teacher Education / M.

Text in Afrikaans / Die studie fokus op die effek van krisiswerk op die helper in terme van stres, die uitbrandingsindroom en posttraumatiese stresversteuring (PTSV). Salutogeniese konstrukte as moderatorveranderlikes in die stres-siekte-verhouding word ook ondersoek. 'n Beskikbaarheidsteekproef van 52 ambulansmanne en 52 kontrolegroepwerkers is verkry. Biografiese, koherensie-, uitbrandings-, PTSV- en stresvraelyste is ingevul en statisties verwerk. Resultate dui daarop dat ambulansmanne hul werk as buitengewoon stresvol beleef en dat meer ambulansmanne diagnoseerbare PTSV vertoon. Daar blyk geen verskil tussen die twee groepe te wees nie met betrekking tot die voorkoms van uitbranding en streservaring. 'n Negatiewe verband tussen koherensiebelewing en die voorkoms van stressimptome en uitbranding is verkry. Ambulansmanne het 'n buitengewoon stresvolle werk en vertoon meer simptome van stresversteurings as mense in ander beroepe. Aanbevelings word gedoen oor hoe om die negatiewe konsekwensies van stres te verminder. / The study focuses on the effect of crisis work on the assistant in terms of stress, the burnout syndrome and post-traumatic stress disorder (PTSD). Salutogenic constructs as moderator variables in the stress-illness relationship are also investigated. An availability sample of 52 ambulancemen and 52 control group workers was obtained. Biographic, coherence, burnout, PTSD and stress questionnaires were completed and statistically processed. Results indicate that ambulancemen experience their work as exceptionally stressful and that more Ambulancemen display diagnosable PTSD. There appears to be no difference between the two groups in respect of the incidence of burnout and experience of stress. A negative connection between the experience of coherence and the incidence of stress symptoms and burnout was obtained. Ambulancemen have an exceptionally stressful job and display more symptoms of stress disorders. Recommendations are made on how to reduce the negative consequences of stress. / Industrial and Organisational Psychology / M. Com. (Bedryfsielkunde)

Die studie foku.s op die verwantskap tussen sin vir koherensie as 'n intrinsieke hanteringsbron aan die een kant, en elk van streshantering, algemene gesondheid en sielkundige uitbranding aan die antler kant. Vraelyste wat hierdie veranderlikes meet is aan 200 bestuurders gegee om te voltooi. Die bevindinge van hierdie studie toon aan dat bestuurders met 'n hoi! sin vir koherensie goeie algemene gesondheid geniet. Die bestuurder met 'n hoi! sin vir koherensie behoon dus meer e.ffektief te junksioneer in die werksiruasie as die bestuurder met 'n lae sin vir koherensie. Voons is ook bevind dar 'n hoi! sin vir koherensie nie noodwendig aanleiding gee tot lae vlakke van stres of van sielkundige uitbranding nie. Aanbevelings word gedoen oor hoe om die negatiewe gevolge van stres en sielkundige uitbranding te venninder en algemene gesondheid te bevorder, ten einde die bestuurder se potensiaal optimaal benut. / This study focuses on the relationship between sense of coherence as an intrinsic coping mechanism. and work stress, general health and psychological burnout. To measure these variables, questionnaires were completed by 200 managers. The findings of this study indicate that managers with a high sense of coherence experience good general health. The manager with a high sense of coherence should therefore junction more efficiently in a work situation·than the manager with a low sense of coherence. It was also found that a high sense of coherence does not necessarily lead to low levels of stress nor of psychological burnout. Recommentfations are made on how to reduce the negative effects of stress and psychological burnout and how to improve general health in order to make optimal use of the manager's potential. / Industrial and Organisational Psychology / MCom (Bedryfsielkunde)

Articular cartilage has a low propensity for self-repair, due to which 27 million people are affected by osteoarthritis every year in North America. The current repair techniques used for cartilage defects possess flaws that reduce long-term clinical success. Tissue engineering carries with it the promise of engineering hyaline-like cartilage with physical and biochemical properties, similar to that of native cartilage. This being said, the primary objective of my project was to engineer clinically relevant sized articular cartilage constructs. To achieve my objective, first, I investigated the effect of continuous culture on cartilaginous tissue growth. Constructs grown under continuous media flow significantly accumulated more collagen and glycosaminoglycan, and displayed a stratified morphology, similar to that found in native cartilage. The second goal was to further increase chondrocyte proliferation, and extracellular matrix (ECM) accumulation. To achieve this, constructs were grown in a bioreactor with media supplemented with 14 mM sodium bicarbonate (NaHCO3). Constructs cultivated in the bioreactor with NaHCO3 supplementation exhibited a significant (p<0.05) increase in ECM accumulation (a 98-fold increase in glycosaminoglycans and a 25-fold increase in collagen content), cell proliferation (a 13-fold increase), and thickness (a 28-fold increase) compared to all other conditions (static and reactor without NaHCO3 supplementation). The third goal was to engineer cartilage constructs with as little cells as possible, reducing donor site morbidity. From the results obtained, it was evident that the monolayer constructs outperformed all the other constructs (pellet, biopsy, and minced). The final goal was to understand the underlying reason for the increased proliferation. First, I investigated if there were any differences present in intracellular pH (pHi) and intracellular buffering capacity. Second, I determined the role of extracellular pH (pHe) on cell proliferation. In an effort to accurately achieve this, I, for the first time, have reported on measuring pHi of chondrocytes while still in culture (2D and 3D cultures) using a confocal microscope. This study demonstrated the importance of extracellular environments, such as pHe, extracellular buffering capacity, and the presence of carbon dioxide and bicarbonate ions for chondrocyte proliferation. / Thesis (Ph.D, Chemical Engineering) -- Queen's University, 2012-10-30 19:19:32.026
