Surface ozone (O3) is one of the most toxic and abundant air pollutants. It has deleterious effects on human and animal respiration processes, and adversely affects plants. Four sites were selected for monitoring ambient O3 in the Durban metropolitan area: Botanic Gardens, University of Natal (UND), top of Kloof Gorge, and Mooi River. At each site tobacco Bel-W3 bioindicators, and NO2 and O3 passive diffusion tubes were placed. An O3 analyser (Dasibi 1108) was situated at the UND site. Monitoring was carried out for four weeks during summer, autumn and winter at each site, and during spring at the UND site. Two weeks of data from the diffusion tubes were collected during spring, from the Nelspruit area, Mpumalanga. Ozone concentrations measured with the Dasibi at the UND site were low in comparison to other urban-industrial areas in the world, with hourly values falling between 5ppb and 10 ppb. The highest hourly mean maximum recorded was 40ppb. A general spring/winter maximum and summer minimum was observed. This is typical of subtropical locations, where subsidence in prevailing anticyclonic circulation occurs. Diurnal characteristics included early morning minima and maxima at 12h00 in spring and summer, and maxima approximately two hours later in autumn and winter. This pattern was typical of that found in polluted environments, the magnitude, however, being lower. An unusual secondary nocturnal peak occurred during autumn, winter and spring. This could have been due to the long-range transport of relatively O3-rich air from a non-urban, high altitude inland area. Ozone concentrations were not strongly influenced by meteorological variables. Diffusion tube data indicated low O3, however, the coefficients of variation were high, implying a lack of precision in this technique. This technique would have to be improved before data obtained could be regarded as valid. Nitrogen dioxide, NO2, one of the precursors to O3, was monitored using diffusion tubes at the same sites. Concentrations were highest closer to the city centre, the highest concentration being 31ppb in autumn. In the Mpumalanga study, NO2 concentrations were higher in the city of Nelspruit than the surrounding areas. No significant differences were found in the O3 concentrations between the Mpumalanga sites. The tobacco plants showed the highest visible leaf injury in winter, corresponding with the higher Dasibi values, but there were no significant differences between the sites, and no significant differences in chlorophyll contents between the sites. In this study, O3-induced injury occurred below the previously established threshold of 40ppb. / Thesis (M.Sc.)-University of Natal, Durban, 1998.

During monitoring of rear-mounted equipment, frequent rearward turning of tractor drivers in awkward postures can cause musculoskeletal disorders related to the back, neck, and shoulders. A camera-based monitoring system, consisting of one or more cameras placed on the implement and a monitor placed inside the tractor cab, has potential ergonomic benefits compared with traditional implement monitoring strategies by reducing the rearward turning and twisting movements of tractor drivers. A camera-based monitoring system was compared with two traditional monitoring strategies (direct looking and using rear-view mirrors) in a lab environment using a Tractor Air-Seeder Driving Simulator. The operator’s reaction time and response errors, head/neck movement (acceleration), and neck muscle temperature were compared for the three monitoring strategies. The camera-based monitoring system yielded significantly (α=0.05) better outcomes in terms of acceleration and muscle temperature values. No significant difference was observed for response errors.

Unscheduled aircraft maintenance causes a lot problems and costs for aircraft operators. This is due to the fact that aircraft cause significant costs if flights have to be delayed or canceled and because spares are not always available at any place and sometimes have to be shipped across the world. Reducing the number of unscheduled maintenance is thus a great costs factor for aircraft operators. This thesis describes three methods for aircraft health monitoring and prediction; one method for system monitoring, one method for forecasting of time series and one method that combines the two other methods for one complete monitoring and prediction process. Together the three methods allow the forecasting of possible failures. The two base methods use decision trees for decision making in the processes and genetic optimization to improve the performance of the decision trees and to reduce the need for human interaction. Decision trees have the advantage that the generated code can be fast and easily processed, they can be altered by human experts without much work and they are readable by humans. The human readability and modification of the results is especially important to include special knowledge and to remove errors, which the automated code generation produced.

Applikationsövervakning är en term för att i realtid övervaka applikationer och kunna upptäcka fel innan slutanvändaren märker av ett problem. Med övervakning av applikationer menas inte bara den enskilda programvaran utan allt som rör applikationen i fråga. Trafikverkets önskemål är att leverera en hög kvalité i sina applikationer. I nuläget har utvecklare ingen eller dålig insyn i hur en applikation levererar i en skarp miljö efter att de lämnat över ansvaret till drift. För att kunna hålla en bra kvalité i sina applikationer så vill de undersöka hur applikationsövervakning kan hjälpa till att se behov av ändringar i applikationer innan större problem uppstår. I en fallstudie bestående av intervjuer och dokumentstudier kommer genom användning av situationsbaserad FA/SIMM nuvarande arbetssätt fångas. Samt fånga mål och problem som uttrycks i verksamheten kring utveckling & förvaltning och drift av applikationer. Dessa kommer sedan analyseras för att undersöka på vilket sätt applikationsövervakning skulle hjälpa utvecklare & förvaltare, men även driftspersonal i deras arbete. Resultatet av detta visar att de problem och mål som tas upp dels är organisatoriska i sin natur och arbetssättet DevOps framhålls som en möjlig lösning. Även att applikationsövervakning de facto skulle kunna bidra till en ökad kvalité i applikationerna genom att tillföra en möjlighet att arbeta mer proaktivt. / Application monitoring is a term for real-time monitoring of applications to be able to discover faults before they reach the end-user. Application monitoring does not only mean the individual software but also everything surrounding it, which can have an impact on the application. Trafikverket wishes to deliver high quality in their applications. At present the developers have no or little insight in how an application delivers in a live environment after they handed over the responsibility to the operations. In order to maintain a good quality of their applications they want to explore how application monitoring may help to see changes in the needs of applications before major problems occur. In a case study consisting of interviews and document studies and through situation based FA/SIMM present ways of working will be produced. It will also identify wishes/concerns expressed by the developers and operations departments in the managing of existent applications. These will then be analyzed to examine in which way application monitoring would help developers, but also operations, in their work. The result shows that the problems which are brought forward are in a sense organizational of nature and that DevOps is a possible way for solution. But also that application monitoring could contribute to the delivery of high quality in applications in a proactive manor.

The main objective of this master thesis is a comparative effectiveness analysis of selected social media monitoring tools. The theoretical part of the thesis first familiarizes the reader with the core terms, which will be used throughout the thesis. The next chapter focuses on the detailed specification of classic online marketing. It describes the growing trend of social media marketing and charts out its current status on the Czech online market. In addition, the vital SEO and SEM techniques are also described. The subsequent chapter is devoted to social network marketing, where the increasing power of "word of mouth" in purchase behavior, is explained. Last but not least, illustrative examples of the most successful social media marketing campaigns are listed. The next part deals with the issues of monitoring social media. The reasons for monitoring social media, its principles and features are stated in this chapter. The practical part of this thesis has a described methodology for testing selected tools, acceptance criteria and metrics of measurement. The selected tools are compared in terms of qualitative properties and the relevance of results, both from a global perspective with English phrases, as well as from the perspective of local phrases suitable for the Czech environment. In the second test a set of free monitoring tools is determined and compared with the tools from the first test. In the conclusion is the last measurement, which is proposes the most appropriate monitoring tool for small sized Czech company.

Self-monitoring involves teaching students to be aware of their own behavior, and be able to record whether the behavior happened or not. The present study uses meta-analysis of single case design (SCD) studies to evaluate the effectiveness of self-monitoring interventions that use electronic devices during implementation for individuals with autism spectrum disorder (ASD). Eligible studies were accessed to determine design quality, and examine the use of self-monitoring for individuals diagnosed with ASD. Studies were evaluated against inclusion-exclusion criteria. The studies that met inclusion criteria (n = 15) were assessed with the What Works Clearinghouse (WWC) standards for methodological rigor. The WWC standards were applied to baseline and intervention phases. There were a total of 12 studies with 32 students diagnosed with ASD that met SCD standards without, and with reservations. The 12 studies were evaluated using the Tau-U effect size metric to quantify the percentage of change that was attributed to the self-monitoring intervention. Overall, omnibus Tau-U was 0.96 (95% confidence interval [CI] = [0.89, 1.0]). Limitations and directions for future research are discussed.

Diese Dissertation umfasst drei Aufsätze über die Rolle von Informationsintermediären und Intermediäre mit Aufsichtsfunktionen in Kapitalmärkten. Der erste Aufsatz untersucht, ob sich verschiedene Leerverkäufer bei ihrer Auswahl von Zielunternehmen anhand von sichtbaren Merkmalen unterscheiden. Die Ergebnisse zeigen, dass Hedgefonds und Investmentmanager im Durchschnitt größere und jüngere Unternehmen bevorzugen, während sich Banken auf Unternehmen mit weniger Restatements der Finanzdaten und einem höheren Verschuldungsgrad konzentrieren. Der zweite Aufsatz beschreibt, wie Unternehmen auf aktivistische Leerverkäuferberichte reagieren. Es wird festgestellt, dass die Antwortrate erheblich steigt, wenn der Bericht von deutlich negativen abnormalen Renditen begleitet wird und wenn die Leerverkäufer neue Beweise vorlegen. Dies stimmt mit der Vorstellung überein, dass Leerverkäufer als Informationsintermediäre fungieren können. Eine Nichtbeantwortung ist außerdem ist mit einer weniger negativen Aktienkursreaktion bei Veröffentlichung und mit weniger nachteiligen Ergebnissen verbunden. Die dritte Aufsatz fokusiert sich auf so-genannte Monitoring Trustees. Sie sind bei der Überwachung von Banken behilflich, die in der Europäischen Union während der letzten Finanzkrise staatliche Beihilfen erhalten haben. In einer von Hand gesammelten Stichprobe werden die Merkmale und Aufgaben dieser neu implementierten Aufseher und ihre Rolle im Zusammenhang mit dem Berichtsverhalten der Banken untersucht. Die Ergebnisse deuten darauf hin, dass diese zusätzlichen Aufseher die Transparenz und das Berichtsverhalten der Banken bei der Finanzberichterstattung beeinflussen können, insbesondere wenn die Berichterstattung über Kreditverluste und Anpassungen der Geschäftsberichte berücksichtigt werden. Der zweite Aufsatz wurde im Journal of Accounting Research (https://doi.org/10.1111/1475-679X.12356) publiziert. / This dissertation comprises three essays on the role of information and monitoring intermediaries in capital markets. The first essay investigates whether different short sellers vary in their selection of target firms using observable firm characteristics. Results show that hedge funds and investment managers on average prefer larger and younger firms, whereas banks focus on firms with fewer restatements and a higher leverage. The second essay provides descriptive evidence on how firms respond to activist short seller reports and how these responses are associated with outcomes for the targeted firms. It finds that the response rate increases substantially when the report is accompanied by significantly negative abnormal returns and when the short sellers provide new evidence which is consistent with the idea of short sellers acting as information intermediaries. Not responding is associated with a less negative stock price response when the report is released and fewer adverse outcomes. The third essay shifts the attention to Monitoring Trustees who assist in the supervision of banks that have received state aid in the European Union during the last financial crisis. It explores in a hand-collected sample the characteristics and duties of these newly implemented monitors and it studies the role of these supranational monitors and the banks’ reporting behavior. Results suggest that these additional supervisors can influence the banks financial reporting transparency and reporting behavior when mainly loan loss reporting and restatements are accounted for. The second essay has been published in the Journal of Accounting Research (https://doi.org/10.1111/1475-679X.12356).
