Comparative analysis of self-administrative energy audit tools for hotels

Supervisor: Prof. Dr. Claudia Simons-Kaufmann, Philipp Sloan (M.A.), Willy Legrand (M.Sc.)

The following thesis discusses the topics of sustainability, environmental management, energy management, environmental, energy and self auditing, software quality and functionality. From the literature the author derives functionality criteria for free of charge online selfadministrative energy audit (FOSEA) tools. The author furthermore introduces currently available tools and compares the functionality of those tools by performing a value benefit
analysis (VBA). In order to scientifically support the VBA the author uses structures from the analytical hierarchy process (AHP) to weigh the importance of the different functionality criteria. The VBA and the AHP were performed by representatives of the Hyatt Regency Cologne (HRC) and the President Hotel Bonn (PHB). The results from the AHP indicate that differences exist in the weighting of the functionality criteria, between representatives from chain and independent hotels. The results of the VBA points out that the FOSEA tool from the Energie-Sparprogramm developed by the DEHOGA fulfills the functionality criteria the most out of the seven assessed tools. However, the analysis also showed that no tool fulfills every criteria of functionality. Additionally, it was pointed out that the weightings derived from the AHP influence the results of the VBA to a great extent. The author came to the final conclusion that this thesis gave valuable insights into the functionality of FOSEA tool and provided recommendations for the developers of such tools, however further research has to be conducted supporting these findings.

The Potential of Continuous Descent Approaches at the Example of Night Flights at Cologne Bonn Airport

Supervisor: Prof. Dr. Hansjochen Ehmer, Prof. Dr. Christoph Brützel

This thesis contains an outline about the potential of Continuous Descent Approaches (CDA) illustrated at the example of night flights at the airport Cologne Bonn. First of all, aviations dependence on night flights and the consequences of nighttime aircraft noise are analyzed. In the following, the benefits and problems of CDAs are discussed in general before the Approach is evaluated for Cologne Bonn in specific. The example of Cologne Bonn emphasizes the high potential of CDAs in particular for specialized airports with high numbers of night movements. By means of a radar track analysis the effect of CDAs on over flight altitude above populated areas around the airport Cologne Bonn is determined. The investigation further concludes which areas benefit most in terms of noise. Moreover, the CDA's effects on fuel consumption, gas emissions and the monetary savings of airlines in Cologne Bonn are figured out. Apart from the advantages, also the disadvantages and problems of the CDA from the Air Traffic Control's and pilot's point of view are discussed.

Work Engagement & Burnout Prevention

Supervisor: Prof. Dr. Ralf Lanwehr, Prof. Dr. Daniel Assmus

The aim of this study was to extend the job demands-resources (JD-R) model by ultiple job demands, job resources, and personal resources, to compare it with the effort-reward imbalance (ERI) model and validate the reliability of both constructs among clinical burnout inpatients. Moreover, we wanted to further validate the Oldenburg Burnout Inventory (OLBI) and to contribute to the creation of a Job Demands-Resources- Personal Resources Scale (JD-R-PR-S).
The study is based on data from 30 clinical burnout inpatients. Regression analysis revealed work-home conflict, workload, and role conflict as key burnout antecedents with positive effect on exhaustion and depersonalization. Mental load can also be considered a burnout antecedent with a positive effect on exhaustion. Job resources (supervisor support, participation in decision making, interactional justice, and learning opportunities) and personal resources (self-efficacy, optimism, internal work locus of control, and organizational-based self-esteem) can be seen as engagement antecedents, as they buffer depersonalization. Furthermore, distributive justice, optimism, and internal work locus of control have a negative impact on the second core burnout component: exhaustion. We found many similarities between the ERI- and JD-R model and could identify overcommitment as the unique component of the ERI model, having a significant relationship with both core burnout dimensions.

Theme of the thesis:
Price Competition in Duopolies - A Game-Theoretic Analysis on the Example of the Domestic Air Transport Market from Berlin to Cologne

Supervisor: Prof. Dr. Karsten Leibold

The main objective of this bachelor thesis is to evaluate the correlation between air fares set by individual airline companies and the profitability of their flight operations. Additionally, a validation of traditional competition models is performed, in order to assess their applicability to duopolistic airline markets. The primary research necessary for the achievement of these objectives is based on data provided by Deutsche Lufthansa AG reflecting the market environment of the route from Berlin to Cologne, which is defined as the object of this causal study. Prior to analysing the market data the hitherto existing literature is perused. The major findings from this review are twofold. Whereas on the one hand, in 1883 Joseph Bertrand published his work constituting the impossibility to run profitable business operations in duopolistic markets, on the other hand modern game theory contradicts this hypothesis. With their conceptionalisation of the idea of coopetition in 1996, Adam Brandenburger and Barry Nalebuff most importantly contribute to this topic. They propose to perceive the other players in a market not only as rivals, but also as partner, in order to create win-win situations in otherwise devastatingly competitive environments. The subsequent concrete data evaluation substantiates the conclusions drawn from the literature review. Furthermore, it reveals the independency of the price setting strategy applied by Lufthansa from the mechanisms used by Air Berlin and vice versa. As price campaigns do not directly impact on the fares charged by the competition, the model of trigger strategies is unsuitable for managerial decision making. Therefore, this thesis concludes with the recommendation of co-opetitive behaviour for airlines serving duopolistic domestic markets, because it proves to be the most adequate and effective tool to understand and predict the dynamics of price competition. Due to its comparably small sample size and limited scope, the author intents this work to be rather thought-provoking than universally valid. Thus, further ideas for future research are incorporated into this bachelor thesis.

Regulation in Case of the Disturbance of the European Airspace - the European Ash Cloud of April 2010

Supervisor: Prof. Dr. Hansjochen Ehmer

Date of submission: 25. August 2010

This thesis contains an examination of the costs of governmental regulations in the European member states in the wake of the eruption of the Icelandic volcano Eyjafjallajökull in April 2010. The costs of the regulations, which resulted in a one-week Europe-wide airspace closure, are analyzed by the application of Williamson's transaction cost approach. By means of a modification of Williamson's attempt to determine the most efficient asset supply of a firm, the inefficiencies of the current air transport policy in the EU are pointed out. The examination reveals that under the principle of subsidiarity, which is relevant to the relation of the EU to its member states, an integration of air transport policy to the European regulation level is overdue. To tackle the congestion of the European airspace and to develop preventive measures against potential future volcanic eruptions, the implementation of a single European sky is the only sustainable solution.

Gender Differences in Perception of Business Ethics - A Case Study of Students at the International University of Bad Honnef · Bonn

Supervisor: Prof. Dr. Stefan Zagelmeyer

Date of submission: 14. September 2009

The purpose of this thesis is to find out whether there is a difference between female and male student's perception in ethical decision-making and attitudes. Special focus was given to the International University of Bad Honnef - Bonn, Germany. Secondary research revealed that there is no clear verification of gender related differences towards ethical decision-making. Numerous tools and measures have been developed in order to find significant differences, however not offering significant findings. Primary research revealed some significant differences between male and female students, nevertheless not resulting in any clear results. Female students show slightly more ethical concern in the vignette situations (MEV), rating the ethical dilemma situations after a more deontological approach (rules and law-abiding) towards ethical judgment. Individual trait rating and the comparison between male and female students revealed the importance of traits such as honesty and trustworthiness. The most important recommendation that can be given to students is to begin with ethical education during the study program in order to prevent stressful ethical dilemma situations. Not only will individuals benefit from this on a personal level but also companies as this may prevent wrong economical situations in aspect to business ethics.

A Factor-Cluster Analysis of Heritage Tourists' Travel - Motivations to Visit a Cultural Heritage Site in Germany

Supervisor: Prof. Dr. Claudia Möller

Date of submission: 26. June 2009

The cultural and heritage tourism market has become an increasingly important area of interest due to its share of approximately 40 % of the worldwide tourism market. Many previous studies analyzed cultural heritage tourists, but no study has focused solely on the German market. Therefore, the purpose of this study is to investigate the travel motivations of German tourists to visit a cultural heritage attraction by adopting the theory of push and pull motivators as the theoretical framework. First, theories with respect to heritage tourism, market segmentation, and travel motivations are described. On the basis of these theories, a questionnaire was developed to gather primary data at the World Heritage Site Sanssouci. Afterwards, factor and cluster analyses were employed to segment the German heritage tourism market. The results of factor analysis revealed three push and three pull factor dimensions. Among them, ‘rest and relaxation' and ‘heritage attractiveness' were viewed as the most important push and pull factors, respectively. Based on cluster analysis, the author identified three distinct segments within the German heritage tourism market. These segments were compared based on demographic and behavioral characteristics. The results of this thesis provide implications for managers of heritage attractions to develop effective marketing strategies for each segment.

Linking employee satisfaction to casino restaurant performance: A pooled cross-sectional correlation and regression analysis

Supervisor: Prof. Dr. Daniel Assmus

Date of submission: 27. Februar 2009

This study uses pooled correlation and regression analysis to analyze the relationship between employee satisfaction and customer satisfaction in gaming centric casino restaurants over a period of 3 consecutive years for three different regions and three different restaurant types (buffet restaurant, coffee shop, and steakhouse). The nature and the strength of the relationship vary depending on front and back-of-the-house employee satisfaction, on different restaurant types, and on different regions and years. The results of this study show that there is a positive correlation between employee satisfaction and customer satisfaction in gaming centric casino restaurants. Furthermore, the findings indicate that back-of-the-house employee satisfaction has a positive correlation to overall customer satisfaction. This relation is even stronger for back-of-the-house employees in the steakhouse and customer satisfaction in the steakhouse showing a medium correlation accounting for 75% of variance in customer satisfaction. These numbers emphasize the importance of satisfied kitchen staff in restaurant concepts with a high level of service. Further research should also differentiate between front-of-the-house and back-of-the house employee satisfaction and different restaurant types. Management implications are provided in the last chapter of this study.

Impacts of Personal Relationships on Brand Loyalty in B2B Markets (at the Example of the Catering Industry)

Supervisor: Prof. Dr. Ralf Lanwehr

Date of submission: 29. September 2008

In today's challenging economy, establishing and maintaining customer relationships as well as a successful branding strategy are major components in order to profitably run an organization. A lot of academic research thus is focusing on the development of customer's long-term orientation. Nevertheless, the impacts of emotional bonding and personal relationships between seller and buyer on this process are not well researched yet. Based on literature review on current academic research, a theoretical framework is developed. Using primary data gathered from customers of a leading German event catering company, this framework is tested. Applying structural equation modeling and multiple regression analysis, underlying structures towards building long-term relationships are investigated. It was found that the tested model shows no statistical significance for the chosen market segment. However, the analyses revealed some indicators that emotions and personal relations should not be underestimated by managers. Even though many limitations occurred for this study and not all results are favorable, managerial implications are named and suggestions for further researcher on this topic are offered.
