In order to maximise the benefits and minimise the risks associated with this practise, and ensure compliance with the laws, the clear identification and sound knowledge of existing or developing limit values of water quality is of crucial importance, when planning and creating water reuse schemes. In this study, the water quality requirements in terms of limit values of treated waste water for agricultural irrigation set in the legislation of different countries and regions (i.e. European Union, Germany, North Rhine-Westphalia, Italy and Spain) were investigated. In the eventuality of a regulatory gap, the requirements set in other pieces of legislation regulating the quality of water for agricultural irrigation or other uses were provided. The purpose of this work is to support the decision making of a subject planning to reuse water for agricultural irrigation, but is not aware of the legal framework regulating this activity.}, language = {en} } @masterthesis{Haehn, type = {Bachelor Thesis}, author = {H{\"a}hn, Fabian}, title = {The Disclosure of Alternative Performance Measures at the German Capital Market}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-2114}, school = {Hochschule Rhein-Waal}, pages = {93}, abstract = {While the regulation of non-standardized, voluntarily disclosed earnings figures - so- called Alternative Performance Measures (APMs) - has been part of the standard setting for over a decade now in the USA, the first extensive legally binding regulations for the EU and Germany have been coming into action in 2016 with the ESMA Guidelines on Alternative Performance Measures. In order to evaluate the impact of the guidelines on the APM reporting behavior of German large stock-listed companies, the annual reports of an adjusted sample of DAX30 and MDAX corporations are examined for the financial years 2014, 2015, and 2016. The empirical results show a slight decrease in the dissemination of APMs when comparing the results for 2015 and 2016. Moreover, the portion of companies reconciling the adjustments made in the calculation of APMs has increased significantly in the post-ESMA Guidelines period while the number of annual reports without any reconciliation has declined simultaneously. Furthermore, the results indicate a significant decrease in the amount of adjustments between normal and modified earnings figures that are published by the same company when comparing the periods prior and subsequent to the issuance of the ESMA Guidelines. A comparison to the developments in the USA following Regulation G shows a much smaller impact of the ESMA Guidelines on the countries' companies. Nonetheless, this may be due to the differences in structure and competencies between the securities authorities in the US and the EU. However, it can be concluded that by reversing the trend of an increasing use of APMs, the ESMA has achieved some of its goals.}, language = {en} } @masterthesis{Nolte, type = {Bachelor Thesis}, author = {Nolte, Johannes}, title = {Untersuchung der Vorgehensweise ausgew{\"a}hlter Internetplattformen gegen gef{\"a}lschte Online-Bewertungen}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-2126}, school = {Hochschule Rhein-Waal}, pages = {52}, abstract = {Diese Arbeit dokumentiert ein Experiment zur Untersuchung des Umgangs von Facebook, Google Maps, Google Play Store und Zalando mit gef{\"a}lschten Bewertungen („Opinion Spam").

The question is how to manage the employees in this global context. This study looks at the use of international assignments as a solution of transferring employees internationally. Especially, this paper focuses on the reintegration of internally assigned employees. Corresponding to the literature, the reintegration proves to be the most difficult stage in an international assignment, as most companies still underestimate the impact and do not invest sufficient in this phase. Therefore, the thesis aims to identify how the reintegration is handled in organizations and which aspects can be considered as critical in this process. Consequently, on the basis of analysis, the author comes up with improvement options. In order, to receive detailed insights in the experiences and opinions of dispatched employees and human resource managers of multinational companies, the author used a qualitative research method (expert interviews). Results show that there is not a great need for cultural reintegration measures, as expatriates assume coming home to be easy and human resource managers do not see the willingness and demand for such arrangements. Anyhow, interviewees described problems in the new work environment and mentioned the request for some enhancements. Therefore, this thesis discusses improvement options for the re-entry, including a reintegration plan set in agreement with the employee and the company before the assignment.}, language = {en} } @masterthesis{Dogotari, type = {Bachelor Thesis}, author = {Dogotari, Marcel}, title = {Hardware Design and RF Performance Evaluation of a Long Range 2.4 GHz Radio Module}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-2158}, school = {Hochschule Rhein-Waal}, pages = {90}, abstract = {Low-power, long-range wireless solutions are needed for transmission of environmental and industrial monitoring data from remote, battery-driven sensors.

The module's power consumption is satisfactory, but its range has to be improved. The accuracy of time-of-flight (ToF) distance estimation, an extra feature of the module, has not been evaluated.

The project objectives are to determine the radar signal distortion caused by vibrations theoretically, conduct simulations to evaluate the effects of vibrations on the human tracking process, and develop a basic model to compensate the disturbing vibrations. The single radar pulse simulations conclude that when the radar is vibrating at a low frequency, the signal would not be distorted if the change of phase of the intermediate frequency is less than half a resolution cell. While the results from the multiple radar pulses simulations reveal that factors like the SNR value, vibrating amplitude and the target's velocity would influence the human tracking process. The higher the SNR value, vibrating amplitude and target's velocity, the more the detected ghost targets when there is only one target presence. A signal demodulation method is then proposed which indicate the possibility in reducing the disturbance caused by the vibrations.}, language = {en} } @masterthesis{Brennhaeusser, type = {Bachelor Thesis}, author = {Brennh{\"a}ußer, Kristin}, title = {Wege zur Optimierung des Fehlermanagements im Krankenhaus durch die Ber{\"u}cksichtigung des Safety-2-Prinzips}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-2182}, school = {Hochschule Rhein-Waal}, pages = {50}, abstract = {Die vorliegende Arbeit hat zum Ziel, Schw{\"a}chen aktueller Praktiken des Fehlermanagements in Krankenh{\"a}usern aufzudecken und herauszustellen, dass die Einf{\"u}hrung einer neuen Herangehensweise notwendig ist.

However, with a large number of overseas Chinese students returning to work in recent years, some disadvantages of returnees gradually appear that the experiences of studying abroad have been unable to satisfy domestic employers' needs. In this bachelor's thesis, the questions on "whether overseas studies still maintain the large benefits on employability for the majority of returned Chinese overseas students, and if not, what are the reasons?" were answered to explore the employability between Chinese returnees and the local graduates. In order to get better analysis, appropriate methods (secondary analysis, literature review, questionnaire, and so forth) were implemented during the study, which questionnaire was considered as the main research measure to update the current condition. The results were somewhat different from the previous studies which indicated a more positive attitude towards the returnees' employability. Overseas qualifications were not considered as a decisive factor for employment in the Chinese market that more comprehensive experiences were required. Overall, the thesis is possible to provide people with a clearer understanding in the current employability of Chinese students under different study background.}, language = {en} } @misc{Shaji, type = {Master Thesis}, author = {Shaji, Anith}, title = {The Implementation and Enhancement of Timesheet Management Process Based on Stored Procedure via .NET}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-3411}, school = {Hochschule Rhein-Waal}, pages = {81}, abstract = {Stored Procedures perform a significant role in the implementation of complex business logic in the database management system.

More often than not, some of these benefits are either mutually exclusive or come with negative impacts on the society or the environment. Hence, estimating the monetary value of these benefits is essential in decision making and policies on scarce natural resources. This thesis aims at estimating the monetary value of about 200 ha of the remaining Hambach forest which was once about 8,500 ha. In recent years, this forest has been the focus of numerous protests from environmentalists who believe that the German energy company RWE should not continue cutting down forest trees in order to extract its rich lignite reserves for electricity production. The environmentalists cite the loss of biodiversity and climate change as the base of their argument but fail to support this statement with an actual valuation study of the existing forest. On the contrary, RWE values the Hambach mine at €4 to €5 billion. In this light, this thesis makes a generous attempt at placing a monetary value on the 200 ha of Hambach forest using benefit transfer and meta-analysis as the main valuation techniques. Moreover, other techniques for a possible primary valuation project are elucidated. Besides, the social and environmental impacts of lignite mining are examined. Eventually, the obtained results are analyzed and discussed along with a concluding chapter on possible solutions and subsequent developments.}, language = {en} }
