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.

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.

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.

Adapting means changing and as the culture of an organization is the fundamental base it has to change, too. Deduced from that development in science this paper investigates methods to change organizational culture and evaluates which of these methods are sensible to do so. The interventions Laboratory Training, Survey Feedback and Process Consultation are compared by assessing studies that tested the effect of those methods. The results of that comparison show that all three intervention types are useful to change organizational culture but for different cultural aspects and in different stages of the change process. Laboratory Training should be applied at the beginning of the change process in order to change attitude and strengthen the commitment to change. Survey Feedback should be used whilst developing the new culture to obtain feedback from employees and increase their involvement in the change process. Finally Process Consultation can support the implementation of the new culture in specific departments.

Fast pyrolysis has received considerable attention in the conversion of biomass into bio-oils which can be used for transportation fuel production. However, bio-oil produced from conventional fast pyrolysis has poor quality mainly due to its high amount of oxygenated compounds and requires upgrading before it can be used as transportation fuel. Catalytic upgrading is a prospective process in which oxygen can be removed from the bio-oil using a catalyst, which was studied in this paper. The main objective of this paper is to investigate the catalytic effects of six applied catalysts on the quality of the bio-oil derived from wheat/barley straw biomass. Fast pyrolysis of the biomass feedstock was performed in an ablative reactor at 550 ℃, and the pyrolysis vapors were led through a catalytic layer (at 400 ℃) in a second reactor for upgrading. Different properties were analyzed for evaluating the quality of the upgraded bio-oils, including water content (for calculating organic content), total acid number (TAN), higher heating value (HHV), elemental composition, and chemical composition. It was found that all catalysts, especially activated carbons (SC40 and SC44), reduced the tarry phase yield with increasing aqueous yield, resulting in the upgraded bio-oils with lower carbon and higher oxygen contents due to their catalytic activities. Moreover, the use of catalysts significantly reduced the sulfur content,making the final bio-oils more attractive due to the environmental concerns. SC40 was the best catalyst in increasing phenols yield and decreasing acids and ketones yields. The zeolite catalysts showed good selectivity to phenols production; the increasing load of nickel ions (Ni) on HZSM-5 slightly enhanced the formation of phenols and eliminated the formation of acids and ketones compared to unmodified HZSM-5. The upgraded bio-oil is still not qualified to be used as transportation fuels.

Today, companies need to be capable to develop software with good usability to stay competitive. This can be achieved by practicing human-centred design (HCD) during the development process. However, especially small and medium-sized software enterprises (SMEs) still practice HCD on a low level, if at all. This thesis explores whether and how the approach of process capability assessment can support SMEs with a systematic improvement of HCD. It is shown that a process capability assessment for usability at SMEs can only be successful, when the first steps of initiating HCD are al-ready done. Then, a process assessment approach seems to be useful to systematically improve the usability capability at SMEs. Based on this theoretical background, a usability capability self-assessment tool tailored for SMEs is developed. It has a simplified assessment procedure and uses the DIN EN ISO 9241-220 as reference model. The self-assessment tool was applied at two German software SMEs to test whether the approach is useful for SMEs and whether the reference model is suitable. The results indicate that the usability self-assessment tool is a promising approach for future SMEs as several interesting applications were identified. The chosen reference model seems to be an appropriate choice for a self-assessment; only the complex language used in the standard impedes the assessment.

For instance; category "Automotive" is assigned to car manufacturer BMW AG. The classification allows the company to evaluate its revenue and profits on different customer segments which, in turn, has an impact on Schenker's strategic planning. Until now the assignment is carried out manually which means that someone from sales department should perform some research on a customer's public profile whenever a new customer is registered in the database. With the rapid growth of global trade in recent years and Schenker's expansion to the Asian market with thousands of new customers the manual approach is no longer sustainable in a global market. This thesis provides an alternative solution based on scraping customer data available in the web and classification of the extracted content. We deal with three significant difficulties: find web data related to a given customer name (we do have a company name but no homepage URL in Schenker database), extract a predictive portion of the data without introducing too much noise and, finally, set up a classification algorithm. Most importantly, the whole process needs to be implemented automatically. For the classification task, we have identified two tree-based classification algorithms random forest and extreme gradient boosting (xgboost). Random forest performs better by using package ranger with an overall 52\% accuracy and 87.8\% multiclass area under the curve.

Des Weiteren sollten Besch{\"a}ftigte ausreichend weitergebildet werden, um den neuen Anforderungen der Industrie 4.0 gewachsen zu sein. Diese Faktoren spielen eine große Rolle in der Pr{\"a}vention von Arbeitsplatzunsicherheit. Aus den Ergebnissen der vorliegenden Arbeit lassen sich wichtige Anregungen f{\"u}r die organisationale Praxis ableiten. Um die Gesundheit ihrer Mitarbeitenden zu sch{\"u}tzen und die Effektivit{\"a}t des Unternehmens besonders in Zeiten der Industrie 4.0 aufrecht zu erhalten, sollten Unternehmen somit besonderen Fokus auf die Vorbeugung von Arbeitsplatzunsicherheit legen.}, language = {de} } @techreport{Walter, type = {Working Paper}, author = {Walter, Phil}, title = {Handeln der Verwaltung}, url = {http://nbn-resolving.de/urn:nbn:de:hbz:1383-opus4-3780}, pages = {7}, abstract = {Es geht um verschiedene Handlungsformen der Verwaltung.

This is due to demographic changes, which bring about an imbalance between eligible donors and possible future recipients. Hence, these changes pose a great challenge in meeting the demand for plasma and plasma-derived products in the future. As plasma cannot be synthesized, recipients depend on voluntary plasma donors. In order to ensure a sufficient supply of plasma considering the ongoing process of aging population, it is crucial to understand why people engage in donation behavior and which factors influence their decision to maintain the donor career. The current study investigates the determinants of plasma donation intention using an extended version of the theory of planned behavior. As the study is conducted in cooperation with Octapharma Plasma GmbH, a subsidiary of one of the largest worldwide operating providers for plasma preparations, the analysis is based on the company's donors only. By using an online questionnaire, data of N = 1153 plasma donors is surveyed in order to examine the hypotheses. Multiple hierarchical regressions reveal significant predictors for plasma donation intention for all donors combined and also for both first-time and repeat plasma donors. Across all donor stages, self-efficacy turns out to be the predominant predictor for future donation intention. Moreover, the satisfaction with the last donation influences all groups of plasma donors in their decision of career maintenance. Therefore, organizations should pay attention to these components, developing strategies to enhance both donors' self-efficacy and donation satisfaction.}, language = {en} } @misc{Roechert, type = {Master Thesis}, author = {R{\"o}chert, Daniel}, title = {Workload Prediction using Apache Spark and R in a Mainframe Operating System}, school = {Hochschule Rhein-Waal}, abstract = {This master thesis presents a machine learning approach using the distributed data- processing framework Apache Spark and the programming language R.

System Management Facility (SMF) data are binary log files that are used to collect system performance data and information about system behaviour. The SMFs show how Apache Spark can be used for the pre-processing. This includes data collection, data extraction, and data selection. The machine learning algorithms are implemented in R. The input SMF datasets will be split into training and test data, and thereby applied to different machine learning and deep learning models such as random forest regression, recurrent neural network, and k-nearest neighbor regression to predict the ApplPerc. The validation of the prediction models will be proved by using cross-validation techniques to evaluate the best applied parameters for each model and therefore to locate the model with the best performance.

The present paper aims to explore the impact of influencer marketing on consumer behaviour in order to offer novel insights to the literature on influencer marketing and to provide the practitioners with meaningful knowledge in the domain. Specifically, the research investigates in-depth how this marketing strategy influences the consumer behaviour during the consumer decision making process and how factors of different nature such as influencers' trustworthiness, consumers' self-esteem and wishful identification as well as sales promotions affect their behaviour. This study applied an inductive, qualitative approach because of the exploratory nature of the research purpose. The empirical study was conducted by means of semi-structured interviews with ten young female adults from the Republic of Moldova. The interviews concentrated on respondents' personal experiences and attitudes regarding influencer marketing and it researched particularly the beauty and fashion industries on Instagram. The findings of this study uncovered and explained the buying behaviour patterns of female consumers that appear as a result of influencer marketing influence throughout the consumer decision making process. Beyond this, the findings illustrate how different influencing factors shape the resultant consumer behaviour.

Lockdown has been implemented in many countries to prevent the virus from spreading. Lockdown has prohibited people to go outside of their houses, closed industries and factories, and restricted air transportation and the free movement of vehicles, except emergency vehicles and flights. On the optimistic side, improvements in ambient air quality due to the lockdown have been reported across the world. This study evaluated ambient air quality by analyzing the PM2.5 concentrations monitored in 7 major cities of Nepal during March, April, and May of the years 2019 and 2020. Furthermore, meteorological data were also evaluated to investigate how meteorological conditions have affected Nepal's ambient air quality during the investigation period. The monthly mean PM2.5 concentrations during March, April, and May 2020 were found to be lower in nearly all of the 7 cities of Nepal as compared to March, April, and May 2019. To some extent, a slightly higher amount of precipitation in March-May 2020 than during March-May 2019 supressed the ambient PM2.5 concentrations in 2020. But, since the highest decrease in PM2.5 concentration was found in Nepalgunj (72.78\%) followed by Kathmandu (46.2\%) during May 2020 as compared to May 2019 and thus, the highest differences between 2019 and 2020 were found for the cities with the highest contribution of transport emissions to PM2.5 in ambient air, the COVID-19 lockdown might have contributed to the lower PM2.5 concentrations in 2020. On the other hand, it can be assumed that one of the major primary sources of PM2.5, biomass burning (both the residential use and natural forest fires), was not affected by the lockdown, but biomass burning might be the reason for the increment of PM2.5 concentrations found at some sites, in particular in the Kathmandu Valley, and for the only subtle decrease at other sites during the lockdown. In essense, though it is an unfortunate situation, the lockdown provided a glimpse of the situation how effective improvements in the environmental conditions could be if we were to introduce large scale mitigation measures swiftly.
