Vor dem Hintergrund aktueller bildungswissenschaftlicher Diskussionen zur digitalen Transformation setzt sich der Beitrag mit der Rolle von Smart Learning Environments (SLEs) in der betrieblichen Weiterbildung und der Notwendigkeit deren interdisziplinärer Gestaltung auseinander. Für eine taugliche, auf den Nutzer fokussierte Gestaltung von SLEs müssen neuartige Konzepte und Modelle entwickelt werden, die den komplexen Anforderungen des 21. Jahrhunderts entsprechen. Der Beitrag beschreibt einen interdisziplinären Forschungszugang zur Gestaltung von SLEs und diskutiert aufbauend ein ganzheitliches, sozio-technisches Framework, das interdisziplinäre Kriterien für eine pädagogisch fundierte Entwicklung von SLEs bündelt. Die Darstellung des Themas erfolgt anhand von aktuellen Befunden aus einer quantitativen Teilstudie eines Forschungsvorhabens der TU Dresden am Fachbereich Bildungstechnologie. Der Beitrag gibt Einblick in den aktuellen Arbeitsstand, wobei die Auswertung der Gesamtstudie umfassendere Befunde erzielen wird.

The main aim of this study was to investigate the role of school management in promoting healthy school environments for Grade R learners in the Sedibeng West District. A literature review revealed that there are two types of health programmes: those that support the curriculum and those that are part of the curriculum. School managers have to focus on both in their efforts to promote health in schools. South African schools adapted a Whole School Approach in creating and sustaining healthy environments. Whole School Approach includes the development of health policies, health education, community, learner, teacher involvement, nutrition and prevention of communicable diseases. A qualitative research approach was used and data was generated by means of interviews, documents, photographs and narratives. Four research sites were purposefully selected and four principals, three Heads of Departments for Foundation Phase, four health coordinators and four Grade R practitioners participated in this research. Only one of the research sites had a School Based Health Centre. The study revealed that curriculum-based health programmes including physical education, physical activities and health education were effectively implemented although they were not effectively monitored and evaluated. Health programmes supporting the curriculum include nutrition, first aid and health services. Both health services and nutrition were effectively implemented and monitored whilst there were serious problems with first aid. Practitioners were not trained for first aid, in the three schools where first aid kits were available were not checked therefore not replenished. In one school there was no first aid kit, thus, there was not much focus on precautionary measures in the participating school. There was therefore, no strategies in place for the management of health programmes that support the curriculum. / MEd (Education Management), North-West University, Vaal Triangle Campus, 2014

Two broad communities can be distinguished in marine systems, those attached to amorphous aggregate material dispersed throughout the water column and those that are freely suspended in the water column (planktonic). It has been suggested that two distinct microbial populations are associated with each habitat due to phenotypic adaptation to the different conditions in aggregates and the surrounding water. The aim of this study was to investigate the diversity of aggregate-associated and planktonic marine ammonia oxidisers (AOBs - the organisms responsible for the rate limiting step in nitrification) in both natural environments and laboratory-reared systems and to determine whether aggregate material selected for particular groups of AOBs. Detection of AOBs relied heavily on the use of molecular analysis of extracted DNA. Thus, a preliminary study was performed to assess whether preferential lysis occurred when representatives of both genera within the B-subgroup AOBs {Nitrosospira multiformis and Nitrosomonas europaea) were exposed to lysis procedures commonly applied to marine samples. Minimal bias existed, with Nitrosomonas europaea proving to be less susceptible to lysis only when the lytic agents (sodium dodecyl sulphate and lysozyme) were absent or at concentrations 100-fold less than those applied in routine environmental extraction. Environmental populations of aggregate-associated and planktonic AOBs in the NW Mediterranean Sea were assessed in summer and winter at stations both within and beyond regions of fresh water inflow (the plume). Molecular analysis involved amplification, by the polymerase chain reaction, of 16S rRNA genes from extracted DNA using AOB-specific primers. Analysis of 16S rDNA sequences coupled with DGGE and specific probing revealed temporal and spatial effects in community structure of AOBs. In the summer, genus level selection of AOBs was observed with Nitrosospira dominating in the aggregate population and Nitrosomonas dominating in the planktonic phase. This was found in the surface waters of geographically distant sites within and outside the plume. Between-site differences were evident in the deeper waters with Nitrosospira-like sequences more abundant in plume diluted waters and Nitrosomonas like sequences more abundant outside this zone, while genus level selection between aggregate-associated and planktonic communities was not detected. In winter, a uniform pattern of AOB distribution emerged with an even distribution of two Nitrosospira sequences at each site on all aggregate and planktonic samples. The AOB community structure of sediment samples was not wholly resolved by application of direct molecular techniques and the culturable diversity was later examined by an enrichment-based approach. A laboratory-reared aggregate system was developed to assess the distribution and selection of inoculated pure and enrichment cultures of AOBs and to assess the effect of sampling technique on the observed community structure. Enclosed vessels containing North Sea water were rotated until aggregation of autochthonous particulate material formed discrete aggregates. No genus level selection of AOBs was observed in aggregate-associated and planktonic communities in North Sea water yet differences in the distribution of closely related sequences within cluster 1 Nitrosospira were observed between the two communities. Observed aggregate and planktonic community structure was affected by the method used to separate the two fractions. Active bacterial production was not necessary for aggregate formation if a pooled suspension of aggregates was sterilised and added to a medium of cell-free filtered sea water. Thus, the successful inoculation and retrieval of an N. multiformis culture within the cell free system suggested that it was appropriate for investigation of the colonisation dynamics of inoculated AOBs.

This thesis is concerned with the development and implications of a critical mode of inquiry into the architectural environment as it is articulated in the photographic projects of German artists Eric Mendelsohn (1887-1953) and Wolfgang Tillmans (b. 1968). These projects are understood as being in opposition to a conventional subordination of photography to architecture. The architectural photograph has consistently been reduced to the role of a tool in the proliferation of structures of global capitalism, facilitating the rise of homogeneous and disconnected built environments. Through an examination and comparison of Mendelsohn’s 1926 book Amerika: Bilderbuch eines Architekten with Tillmans' 2014 video installation Book for Architects, this thesis argues that the visual strategies employed in these works reflect similar concerns regarding the state of architectural practice, providing alternative avenues of inquiry for architects, and highlighting the necessity for deeper engagement with the phenomenological qualities of the architectural environment.

The problem of this investigation was to compare the perceptions of college environments held by college-bound high school seniors, their teachers, and their parents, from a specified geographical area with the perceptions of students actually experiencing the environments represented by these campuses.

Environmental issues from oil production have left inestimable environmental degradation and impacts to the lives of people in the Nigerian oil-producing region (NOPR). Research to date has suggested the importance of stakeholders’ collaboration in managing environmental issues. However, little research has been conducted to understand roles of stakeholders in developing a framework for stakeholders’ collaboration in the NOPR. This research produces a framework for stakeholders’ collaboration to expand knowledge in the development of a collaborative environmental management in the NOPR. The research aim was achieved based on four objectives; 1) identified recommended practices for stakeholders’ collaboration in managing environmental issues and established how they could be applied in the NOPR; 2) investigated stakeholders’ perception of collaborative roles in managing environmental issues in the NOPR; 3) designed a framework for stakeholders’ collaboration for managing environmental issues in the NOPR through the synthesis of outcomes of 1) and 2); and 4) validated the designed framework by identifying the critical success factors for its application. In achieving these objectives, interpretive research was applied, and it was underpinned by stakeholder analysis methodology to provide a coherent research design. Furthermore, the Ostrom’s institutional analysis and development (IAD) framework and the theory of common pool resource were extended to inform the interpretation of collaborative roles of stakeholders in managing environmental issues in the NOPR. Adhering to the theoretical suggestions of stakeholder analysis / IAD framework and to allow a robust investigation of stakeholders’ collaboration, this research focused on the qualitative investigation of roles of the key stakeholders–i.e., Nigerian government agencies, multinational oil companies and host communities. While analysis of selected documents of the key stakeholders was conducted to explore the roles of stakeholders, semi-structured interviews were conducted with a select heads of departments and managers to examine their perception regarding their collaborative roles and critical success factor for stakeholders’ collaboration. While selective manual coding was used for the document analysis, narrative analysis assisted with NVivo 11 was used for the semi-structured interview analysis. The findings from both the document analysis and the review of recommended environmental management practices were synthesized to develop the framework for stakeholders’ collaboration. Policy review and development; strategic environmental management, systematic implementation of environmental management strategies and periodic review of management practices and policies were identified as key components of the framework for stakeholders’ collaboration. Findings from the framework validation derived from the semi-structured interviews show that critical success factors of stakeholders’ collaboration in managing environmental issues in the NOPR are primarily driven by socio-economic interests and political will as well as compliance to environmental management policies. Furthermore, it was found that ignorance and lack of commitment, among other barriers, can hinder stakeholders’ collaboration in managing environmental issues in the NOPR. This research suggests that due to the diversity of stakeholders’ roles regarding their institutional interests and complexity of environmental issues in the NOPR, successful stakeholders’ collaboration would depend on the concerted commitment and genuine collaboration across stakeholders.
