Mit dem Aufkommen von Head-Mounted Displays (HMDs) der aktuellen Generation erlangt Virtual Reality (VR) wieder großes Interesse im Feld von medizinischer Bildgebung und Diagnose. Exploration von CT oder MRT Daten in raumfüllender Virtual Reality stellt eine intuitive Anwendung dar. Allerdings gilt in Virtual Reality, dass das Aufrechterhalten einer hohen Bildwiederholungsrate noch wichtiger ist als bei konventioneller Benutzerinteraktion, die sitzend vor einem Bildschirm erfolgt. Es existieren starke wissenschaftliche Hinweise, die nahelegen, dass geringe Bildwiederholungsraten und hohe Latenzzeit einen starken Einfluss auf das Auftreten von Cybersickness besitzen. Diese Abschlussarbeit untersucht zwei praktische Ansätze, um den hohen Rechenaufwand von Volumenrendering zu überkommen. Einer liegt in der Ausnutzung von Kohärenzeigenschaften des besonders aufwändigen stereoskopischen Rendering Set-ups. Der Hauptbeitrag ist die Entwicklung und Auswertung einer neuartigen Beschleunigungstechnik für stereoskopisches GPU Raycasting. Zudem wird ein asynchroner Renderingansatz verfolgt, um das Ausmaß von Latenz im System zu minimieren. Eine Auswahl von Image-Warping Techniken wurden implementiert und systematisch evaluiert, um die Tauglichkeit für VR Volumenrendering zu bewerten.
Koordinations- und Bewusstseinsmechanismen sind in Computer-Supported Cooperative Work (CSCW) und bei traditioneller Groupware von Wichtigkeit. Die Wissenschaft ist bestrebt, deren Bedeutung bei der Nutzung von Groupware und die damit verknüpfte Zusammenarbeit von Menschen tiefgründig zu untersuchen, um ihre Anwendung und Effizienz zu beschreiben. Dabei wurde bisher noch keine Klassifizierung der Mechanismen vorgenommen, um deren Gemeinsamkeiten und Unterschiede sowie ihre Anwendung herauszuarbeiten und ihrer Bedeutung im kollaborativem Umfeld nachzugehen. Zudem fehlt die Betrachtung der Mechanismen in neuen Formen von Groupware. In der Wissenschaft als auch in der Praxis haben Enterprise Collaboration Systems (ECS), die Social Software Funktionalität beinhalten, wachsende Bedeutung. Basierend auf der Kombination von traditioneller Groupware und Social Software Komponenten beinhalten diese auch Mechanismen, die die Kollaboration vereinfachen sollen, jedoch bisher noch nicht hinreichend untersucht wurde.
Das Ziel dieser wissenschaftlichen Arbeit ist es daher, Beispiele für Koordinierungs- und Bewusstseinsmechanismen in der akademischen Literatur zu identifizieren um einen ersten Überblick über diese zu verschaffen. Aufbauend darauf ist es zudem Ziel, die Beispielmechanismen zu klassifizieren. Basierend auf einer Literaturanalyse werden Konzepte aus der Literatur übernommen und auf die ausgewählten Mechanismen angewendet um diese zu analysieren und zu klassifizieren. Dabei werden die Gemeinsamkeiten und Unterschiede der Mechanismen herauszuarbeiten und beschrieben. Um ein Verständnis für die Anwendung von Koordinations- und Bewusstseinsmechanismen zu verdeutlichen, werden einige Mechanismen exemplarisch visualisiert. Die Beispiele beziehen sich auf die verschiedenen Klassifizierungsgruppen. Die Auswahl der Mechanismen für die Visualisierung basiert auf deren signifikanten Unterschiede in ihrer Funktionalität. Anschließend werden die ausgewählten Mechanismen, die in der Literatur traditioneller Groupware identifiziert wurden, in kleinen Ausmaß in sozial integrierter ECS kon-trollier. Dabei gilt es herauszufinden, ob die Beispielmechanismen vorzufinden sind und ob neue Mechanismen identifiziert werden können. Als Praxisbeispiel von ECS mit Sozialer Software dient die kollaborative Plattform von IBM Connections. IBM Connections wird an der Universität Koblenz eingesetzt, um die Plattform „UniConnect“ zu betreiben. Anhand einer ersten Toolanalyse wird herausgearbeitet, welche von den identifizierten Beispielen an Mechanismen in IBM Connections angewendet werden. Diese Arbeit stellt erste Schritte in der Untersuchung von Koordinierungs- und Bewusstseinsmechanismen in ECS mit Social Software dar. Darüber hinaus sollen Beispiele für neue, bisher unbekannte Mechanismen herausgearbeitet werden, die im Zuge des sozialen Faktors zu kollaborativen Arbeit eingesetzt werden.
Der Beitrag soll dazu dienen, Beispiele von Koordinierungs- und Bewusstseinsmechanismen in der Literatur zu identifizieren, zu analysieren und diese zusammenbringen um einen ersten Überblick zu erhalten. Desweiten wird eine erste Klassifizierung anhand der Unterschiedlichkeiten der Mechanismen vorgenommen. Nebenbei soll der Betrag einen Anreiz für weitere Untersuchungen schaffen, Koordinierungs- und Bewusstseinsmechanismen in sozial integrierter ECS tiefer zu untersuchen.
The European weatherfish (Misgurnus fossilis) is a benthic freshwater fish species belonging to the family Cobitidae, that is subjected to a considerable decline in many regions across its original distribution range. Due to its cryptic behavior and low economic value, the causes of threat to weatherfish remained partly unknown and the species is rarely at the center of conservation efforts. In order to address these concerns, the overall aim of the present thesis was to provide a comprehensive approach for weatherfish conservation, including the development of stocking measures, investigations on the species autecology and the evaluation of potential threats. The first objective was to devise and implement a regional reintroduction and stock enhancement program with hatchery-reared weatherfish in Germany. Within this program (2014-2016), a total number of 168,500 juvenile weatherfish were stocked to seven water systems. Recaptures of 45 individuals at two reintroduction sites supported the conclusion that the developed stocking strategy was appropriate. In order to broaden the knowledge about weatherfish autecology and thereby refining the rearing conditions and the selection of appropriate stocking waters, the second objective was to investigate the thermal requirements of weatherfish larvae. Here, the obtained results revealed that temperatures higher than previously suggested were tolerated by larvae, whereas low temperatures within the range of likely habitat conditions increased mortality rates. As weatherfish can be frequently found in agriculturally impacted waters (e.g. ditch systems), they are assumed to have an increased probability to be exposed to chemical stress. Since the resulting risk has not yet been investigated with a focus on weatherfish, the third objective was to provide a methodical foundation for toxicity testing that additionally complies with the requirements of alternative test methods. For this purpose, the acute fish embryo toxicity test was successfully transferred to weatherfish and first results exhibited that sensitivity of weatherfish towards a tested reference substance (3,4-dichloroaniline) was highest compared to other species. On the basis of these findings, the fourth objective was to apply weatherfish embryos for multiple sediment bioassays in order to investigate teratogenic effects derived from sediment-associated contaminants. In this context, weatherfish revealed particular sensitivity to water extractable substances, indicating that sediment contamination might pose a considerable risk. Moreover, as an endangered benthic fish species with high ecological relevance for European waters that are specifically exposed to hazardous contaminants, the weatherfish might be a prospective species for an ecological risk assessment of sediment toxicity. Overall, the present thesis contributed to the conservation of weatherfish by considering a variety of aspects that interact and reinforce one another in order to achieve improvements for the species situation.
Das Internet der Dinge (IoT) ist ein Netzwerk bestehend aus adressierbaren, physikalischen Objekten, die Sensor-, Kommunikations- und Aktuator-Technologien bereitstellen und mit ihrer Umwelt interagieren (Geschickter 2015). Wie jedes neue Konzept, hat auch IoT Interesse über jeden Anwendungsbereich hinweg, sowohl in Theorie als auch Praxis, geweckt und die verfügbaren Technologien an ihre Grenzen gebracht. Diese Grenzen machen sich insbesondere dann bemerkbar, wenn die Anzahl von Dingen (Things), die über verschiedenste Anwendungsbereiche hinweg verwaltet werden müssen, steigt. Um die neuartigen Anforderungen zu erfüllen, wurde eine Fülle von verschiedenen Systemen entwickelt, die alle ihre eigenen Interpretationen einer IoT Architektur und ihrer jeweiligen Komponenten anwenden. Dies hat dazu geführt, dass IoT aktuell eher ein Intranet der Dinge als ein Internet der Dinge ist (Zorzi et al. 2010). Daher ist es Ziel dieser Arbeit, ein einheitliches Verständnis der Komponenten, die eine IoT Architektur bilden, zu erlangen und generische Spezifikationen in Form eines Ganzheitlichen IoT Architektur Frameworks zur Verfügung zu stellen.
Diese Arbeit verwendet Design Science Research (DSR), um die genannte Architektur auf Basis der einschlägigen Literatur zu entwickeln. Die Entwicklung des Ganzheitlichen IoT Architektur Frameworks umfasst die Nutzung zwei neuer Perspektiven auf IoT Architekturen (IoT Architecture Perspectives), die während der Analyse von IoT Architekturen in der Literatur identifiziert wurden. Die Anwendung dieser neuen Perspektiven führte zur Erkenntnis, dass eine weitere, ebenfalls neuartige, Komponente in der Literatur implizit erwähnt wird. Die Beschreibungen der Komponenten von verschiedenen IoT Architekturen wurden vereinheitlicht und mit der neuen Komponente, dem Thing Management System, in Beziehung gesetzt, um das Ganzheitliche IoT Architektur Framework zu entwickeln. Weiterhin wurde gezeigt, dass die Spezifikationen der Architektur als Vorlage für die Implementation eines Prototypen geeignet ist.
Der Hauptbeitrag dieser Arbeit ist ein vereinheitlichtes Verständnis der einzelnen Komponenten sowie deren Interaktionen einer IoT Architektur.
World’s ecosystems are under great pressure satisfying anthropogenic demands, with freshwaters being of central importance. The Millennium Ecosystem Assessment has identified anthropogenic land use and associated stressors as main drivers in jeopardizing stream ecosystem functions and the
biodiversity supported by freshwaters. Adverse effects on the biodiversity of freshwater organisms, such as macroinvertebrates, may propagate to fundamental ecosystem functions, such as organic matter breakdown (OMB) with potentially severe consequences for ecosystem services. In order to adequately protect and preserve freshwater ecosystems, investigations regarding potential and observed as well as direct and indirect effects of anthropogenic land use and associated stressors (e.g. nutrients, pesticides or heavy metals) on ecosystem functioning and stream biodiversity are needed. While greater species diversity most likely benefits ecosystem functions, the direction and magnitude of changes in ecosystem functioning depends primarily on species functional traits. In this context, the functional diversity of stream organisms has been suggested to be a more suitable predictor of changes in ecosystem functions than taxonomic diversity.
The thesis aims at investigating effects of anthropogenic land use on (i) three ecosystem functions by anthropogenic toxicants to identify effect thresholds (chapter 2), (ii) the organic matter breakdown by three land use categories to identify effects on the functional level (chapter 3) and (iii)on the stream community along an established land-use gradient to identify effects on the community level.
In chapter 2, I reviewed the literature regarding pesticide and heavy metal effects on OMB, primary production and community respiration. From each reviewed study that met inclusion criteria, the toxicant concentration resulting in a reduction of at least 20% in an ecosystem function was standardized based on laboratory toxicity data. Effect thresholds were based on the relationship between ecosystem functions and standardized concentration-effect relationships. The analysis revealed that more than one third of pesticide observations indicated reductions in ecosystem functions at concentrations that are assumed being protective in regulation. However, high variation within and between studies hampered the derivation of a concentration-effect relationship and thus effect thresholds.
In chapter 3, I conducted a field study to determine the microbial and invertebrate-mediated OMB by deploying fine and coarse mesh leaf bags in streams with forested, agricultural, vinicultural
and urban riparian land use. Additionally, physicochemical, geographical and habitat parameters were monitored to explain potential differences in OMB among land use types and sites. Regarding results, only microbial OMB differed between land use types. The microbial OMB showed a negative relationship with pH while the invertebrate-mediated OMB was positively related to tree cover. OMB responded to stressor gradients rather than directly to land use.
In chapter 4, macroinvertebrates were sampled in concert with leaf bag deployment and after species identification (i) the taxonomic diversity in terms of Simpson diversity and total taxonomic
richness (TTR) and (ii) the functional diversity in terms of bio-ecological traits and Rao’s quadratic entropy was determined for each community. Additionally, a land-use gradient was established and the response of the taxonomic and functional diversity of invertebrate communities along this gradient was investigated to examine whether these two metrics of biodiversity are predictive for the rate of OMB. Neither bio-ecological traits nor the functional diversity showed a significant relationship with
OMB. Although, TTR decreased with increasing anthropogenic stress and also the community structure and 26 % of bio-ecological traits were significantly related to the stress gradient, any of these shifts propagated to OMB.
Our results show that the complexity of real-world situations in freshwater ecosystems impedes the effect assessment of chemicals and land use for functional endpoints, and consequently our potential to predict changes. We conclude that current safety factors used in chemical risk assessment may not be sufficient for pesticides to protect functional endpoints. Furthermore, simplifying real-world stressor gradients into few land use categories was unsuitable to predict and quantify losses in OMB. Thus, the monitoring of specific stressors may be more relevant than crude land use categories to detect effects on ecosystem functions. This may, however, limit the large scale assessment of the status of OMB. Finally, despite several functional changes in the communities the functional diversity over several trait modalities remained similar. Neither taxonomic nor functional diversity were suitable predictors of OMB. Thus, when understanding anthropogenic impacts on the linkage between biodiversity and ecosystem functioning is of main interest, focusing on diversity metrics that are clearly linked to the stressor in question (Jackson et al. 2016) or integrating taxonomic and functional metrics (Mondy et al., 2012) might enhance our predictive capacity.
Agricultural land-use may lead to brief pulse exposures of pesticides in edge-of-field streams, potentially resulting in adverse effects on aquatic macrophytes, invertebrates and ecosystem functions. The higher tier risk assessment is mainly based on pond mesocosms which are not designed to mimic stream-typical conditions. Relatively little is known on exposure and effect assessment using stream mesocosms.
Thus the present thesis evaluates the appliacability of the stream mesocosms to mimic stream-typical pulse exposures, to assess resulting effects on flora and fauna and to evaluate aquatic-terrestrial food web coupling. The first objective was to mimic stream-typical pulse exposure scenarios with different durations (≤ 1 to ≥ 24 hours). These exposure scenarios established using a fluorescence tracer were the methodological basis for the effect assessment of an herbicide and an insecticide. In order to evaluate the applicability of stream mesocosms for regulatory purposes, the second objective was to assess effects on two aquatic macrophytes following a 24-h pulse exposure with the herbicide iofensulfuron-sodium (1, 3, 10 and 30 µg/L; n = 3). Growth inhibition of up to 66 and 45% was observed for the total shoot length of Myriophyllum spicatum and Elodea canadensis, respectively. Recovery of this endpoint could be demonstrated within 42 days for both macrophytes. The third objective was to assess effects on structural and functional endpoints following a 6-h pulse exposure of the pyrethroid ether etofenprox (0.05, 0.5 and 5 µg/L; n = 4). The most sensitive structural (abundance of Cloeon simile) and functional (feeding rates of Asellus aquaticus) endpoint revealed significant effects at 0.05 µg/L etofenprox. This concentration was below field-measured etofenprox concentrations and thus suggests that pulse exposures adversely affect invertebrate populations and ecosystem functions in streams. Such pollutions of streams may also result in decreased emergence of aquatic insects and potentially lead to an insect-mediated transfer of pollutants to adjacent food webs. Test systems capable to assess aquatic-terrestrial effects are not yet integrated in mesocosm approaches but might be of interest for substances with bioaccumulation potential. Here, the fourth part provides an aquatic-terrestrial model ecosystem capable to assess cross-ecosystem effects. Information on the riparian food web such as the contribution of aquatic (up to 71%) and terrestrial (up to 29%) insect prey to the diet of the riparian spider Tetragnatha extensa was assessed via stable isotope ratios (δ13C and δ15N). Thus, the present thesis provides the methodological basis to assess aquatic-terrestrial pollutant transfer and effects on the riparian food web.
Overall the results of this thesis indicate, that stream mesocosms can be used to mimic stream-typical pulse exposures of pesticides, to assess resulting effects on macrophytes and invertebrates within prospective environmental risk assessment (ERA) and to evaluate changes in riparian food webs.
For a comprehensive understanding of evolutionary processes and for providing reliable prognoses about the future consequences of environmental change, it is essential to reveal the genetic basis underlying adaptive responses. The importance of this goal increases in light of ongoing climate change, which confronts organisms worldwide with new selection pressures and requires rapid evolutionary change to avoid local extinction. Thereby, freshwater ectotherms like daphnids are particularly threatened. Unraveling the genetic basis of local adaptation is complicated by the interplay of forces affecting patterns of genetic divergence among populations. Due to their key position in freshwater communities, cyclic parthenogenetic mode of reproduction and resting propagules (which form biological archives), daphnids are particularly suited for this purpose.
The aim of this thesis was to assess the impact of local thermal selection on the Daphnia longispina complex and to reveal the underlying genetic loci. Therefore, I compared genetic differentiation among populations containing Daphnia galeata, Daphnia longispina and their interspecific hybrids across time, space, and species boundaries. I revealed strongly contrasting patterns of genetic differentiation between selectively neutral and functional candidate gene markers, between the two species, and among samples from different lakes, suggesting (together with a correlation with habitat temperatures) local thermal selection acting on candidate gene TRY5F and indicating adaptive introgression. To reveal the candidate genes’ impact on fitness, I performed association analyses among data on genotypes and phenotypic traits of D. galeata clones from seven populations. The tests revealed a general temperature effect as well as inter-population differences in phenotypic traits and imply a possible contribution of the candidate genes to life-history traits. Finally, utilizing a combined population transcriptomic and reverse ecology approach, I introduced a methodology with a wide range of applications in evolutionary biology and revealed that local thermal selection was probably a minor force in shaping sequence and gene expression divergence among four D. galeata populations, but contributed to sequence divergence among two populations. I identified many transcripts possibly under selection or contributing strongly to population divergence, a large amount thereof putatively under local thermal selection, and showed that genetic and gene expression variation is not depleted specifically in temperature-related candidate genes.
In conclusion, I detected signs of local adaptation in the D. longispina complex across space, time, and species barriers. Populations and species remained genetically divergent, although increased gene flow possibly contributed, together with genotypes recruited from the resting egg bank, to the maintenance of standing genetic variation. Further work is required to accurately determine the influence of introgression and the effects of candidate genes on individual fitness. While I found no evidence suggesting a response to intense local thermal selection, the high resilience and adaptive potential regarding environmental change I observed suggest positive future prospects for the populations of the D. longispina complex. However, overall, due to the continuing environmental degradation, daphnids and other aquatic invertebrates remain vulnerable and threatened.
The output of eye tracking Web usability studies can be visualized to the analysts as screenshots of the Web pages with their gaze data. However, the screenshot visualizations are found to be corrupted whenever there are recorded fixations on fixed Web page elements on different scroll positions. The gaze data are not gathered on their fixated fixed elements; rather they are scattered on their recorded scroll positions. This problem has raised our attention to find an approach to link gaze data to their intended fixed elements and gather them in one position on the screenshot. The approach builds upon the concept of creating the screenshot during the recording session, where images of the viewport are captured on visited scroll positions and lastly stitched into one Web page screenshot. Additionally, the fixed elements in the Web page are identified and linked to their fixations. For the evaluation, we compared the interpretation of our enhanced screenshot against the video visualization, which overcomes the problem. The results revealed that both visualizations equally deliver accurate interpretations. However, interpreting the visualizations of eye tracking Web usability studies using the enhanced screenshots outperforms the video visualizations in terms of speed and it requires less temporal demands from the interpreters.
Das Internet der Dinge – Internet of Things (IoT) – ist kürzlich der entfernten Vision des Ubiquitous Computing entwachsen und findet nunmehr konkret Eingang in Politik und Wirtschaft, welches sich in aufwendigen Förderprogrammen äußert. Unternehmen sehen sich mit dem von Experten vorhergesagten, gravierenden Wandel von Geschäftsmodellen konfrontiert und müssen darauf reagieren, um im Wettbewerb bestehen zu können. Obgleich daher ein Bedarf zur Strategieentwicklung bezüglich der kommenden Veränderungen in Unternehmen besteht, ist das Thema des organisationsbezogenen Wandels in Hinblick auf die neue Technologie in der akademischen Diskussion derzeit noch wenig präsent. Die vorliegende Arbeit erforscht IoT-verknüpften Wandel in Unternehmen, indem sie un- terschiedliche Arten des Wandels identifiziert und klassifiziert. Sie kombiniert zu diesem Zweck den methodischen Ansatz der gegenstandsbezogenen Theoriebildung (Grounded Theory) mit einer Diskussion und Klassifikation von identifizierten Veränderungen vor dem Hintergrund eines strukturierten Literaturüberblicks im Bereich des Wandels in Organisationen. Diesbezüglich erfolgt eine Meta-Analyse von Fallstudien mittels einer qualitativ-explorativen Kodierungs-Methode zur Identifizierung von Kategorien des organisationsbezogenen Wandels, welcher mit der Einführung von IoT in Verbindung steht. Darüber hinaus wird eine Gegenüberstellung der identifizierten Kategorien mit vorherigem technologie-verknüpftem Wandel am Beispiel von Electronic Business (e-business), Enterprise Resource Planning (ERP)-Systemen und Customer Relationship Management (CRM)-Systemen durchgeführt. Den Hauptbeitrag dieser Arbeit stellt die Entwicklung eines umfassenden Modells von organisationsbezogenem Wandel bezüglich IoT dar. Das Modell präsentiert zwei Hauptthemen des Wandels, welche nahe legen, dass persönliche, intelligente Objekte Unternehmen dadurch verändern werden, dass vermehrt personen-gebundene, mobile Geräte zum Einsatz kommen. Objekte schlagen ihren Nutzern Tätigkeiten oder den gesamten Arbeitsablauf vor und versuchen gefährliche Situationen zu vermeiden. Gleichzeitig wird die Verfügbarkeit von Informationen im Unternehmen bis zur ubiquitären Präsenz steigen. Dies wird es letztlich ermöglichen, Informationen bezüglich Objekten und Personen jederzeit und an jedem Ort zu nutzen. Als Nebenergebnis gibt die vorliegende Arbeit einen Überblick über Konzepte der wissenschaftlichen Literatur im Bereich technologie-verknüpften Wandels in Organisationen.
The extensive literature in the data visualization field indicates that the process of creating efficient data visualizations requires the data designer to have a large set of skills from different fields (such as computer science, user experience, and business expertise). However, there is a lack of guidance about the visualization process itself. This thesis aims to investigate the different processes for creating data visualizations and develop an integrated framework to guide the process of creating data visualizations that enable the user to create more useful and usable data visualizations. Firstly, existing frameworks in the literature will be identified, analyzed and compared. During this analysis, eight views of the visualization process are developed. These views represent the set of activities which should be done in the visualization process. Then, a preliminary integrated framework is developed based on an analysis of these findings. This new integrated framework is tested in the field of Social Collaboration Analytics on an example from the UniConnect platform. Lastly, the integrated framework is refined and improved based on the results of testing with the help of diagrams, visualizations and textual description. The results show that the visualization process is not a waterfall type. It is the iterative methodology with the certain phases of work, demonstrating how to address the eight views with different levels of stakeholder involvement. The findings are the basis for a visualization process which can be used in future work to develop the fully functional methodology.
