Dieser Text soll das Verfassen von Bachelorarbeiten erleichtern. Schrittweise wird dargestellt, wie man recherchiert, wie man eine Bachelorarbeit strukturiert, wie man argumentiert, wie man Ergebnisse darstellt und wie man eine zielführende Diskussion führt. Zwei Meilensteine für eine gute Bachelorarbeit sind das eigenständige Strukturieren von Informationen sowie das Entwickeln einer Argumentationslinie. Informationen sollen nicht unverbunden nebeneinander stehen, sondern argumentativ verknüpft werden. Es werden abschließend Grundregeln des Darstellens und Zitierens erläutert.
Sustainable tourism is a niche market that has been growing in recent years. At the same time, companies in the mass tourism market have increasingly marketed themselves with a “green” image, although this market is not sustainable. In order to successfully market sustainability, targeted marketing tactics are needed.
The aim of this research is to establish appropriate marketing tactics for sustainable tourism in the niche market and in the mass market. The purpose is to uncover current marketing tactics for both the mass tourism market and the sustainable tourism niche market. It also intends to explore how consumers who are more interested in sustainability differ from consumers with less interest in sustainability in terms of their perception of sustainability in tourism. Furthermore, this research paper will assess the trustworthiness of sustainable travel offers and the trustworthiness of quality seals in sustainable tourism. For this purpose, an online survey was conducted, which was addressed at German-speaking consumers. The survey showed, that consumers with more general interest in sustainability also consider sustainability to be more relevant in tourism. Offers for sustainable travel and quality seals were perceived as not very trustworthy. Moreover, no link could be found between the interest in sustainability and the perception of trustworthiness.
On the basis of the above, it is advisable to directly advertise sustainability in the niche market and to mention sustainability in the mass market only as an accompaniment or not at all. Further research could be undertaken to identify which factors influence the trustworthiness of offers, and trustworthiness of quality seals in sustainable tourism.
Mit der Hannoverschen Korruptionsskala Österreich-Version (kurz: HKS 38 Ö) kann die Einstellung zu Korruption gemessen werden. Die HKS 38 Ö ist eine Adaption der Hannoverschen Korruptionsskala (kurz: HKS 38) für den österreichischen Sprachraum. Die testtheoretische Überprüfung der HKS 38 Ö wird unter anderem in diesem Manual beschrieben. Die HKS 38 Ö umfasst 38 Items, die den Einstellungskomponenten kognitiv, affektiv und konativ zugeordnet werden können. Innerhalb dieses Manuals werden drei Datenerhebungen geschildert. In der ersten Datenerhebung (n = 1.617) wurde geprüft, ob die HKS 38 grundsätzlich für eine Anwendung in Österreich geeignet ist und ähnlich zuverlässige Messungen wie in Deutschland ermöglicht. Die Erfahrungen aus der ersten Datenerhebung – insbesondere die Hinweise von Testpersonen zur sprachlichen Verständlichkeit – führten zur Erstellung der HKS 38 Ö. Die HKS 38 Ö wurde im Rahmen einer zweiten Datenerhebung entsprechend der klassischen Testtheorie überprüft und auf Basis einer bevölkerungsrepräsentativen Telefonbefragung in Österreich (n ≈ 867) normiert. Neu im Vergleich zur ersten Auflage des Manuals ist die dritte Datenerhebung, in der die HKS 38 Ö für eine Befragung von Polizeischülern (n = 1.455) verwendet wurde. Auch die Daten der dritten Erhebung wurden testtheoretisch überprüft. Die HKS 38 Ö eignet sich zur Befragung von Testpersonen ab einem Alter von 18 Jahren.
Die Dunkle Triade besteht aus den Konstrukten Machiavellismus, Narzissmus sowie Psychopathie. Nachfolgend wird eine Untersuchung des Zusammenhangs zwischen den Konstrukten der Dunklen Triade und Studienerfolg berichtet. Studienerfolg wurde mittels Durchschnittsnote, Studiendauer, Kompetenzerwerb sowie Studienzufriedenheit operationalisiert und jeweils separat überprüft. Insgesamt wurden 98 Studierende der Hochschule Hannover befragt. Es konnten keine statistisch signifikanten Zusammenhänge zwischen den drei Konstrukten der Dunklen Triade und Durchschnittsnote sowie Studiendauer festgestellt werden. Ebenfalls konnten keine statistisch signifikanten Zusammenhänge zwischen Machiavellismus und Kompetenzerwerb sowie Studienzufriedenheit festgestellt werden. Auch für Narzissmus konnten keine statistisch signifikanten Zusammenhänge mit Kompetenzerwerb sowie Studienzufriedenheit festgestellt werden. Die Effekte dieser statistisch insignifikanten Ergebnisse sind in ihrer Höhe gering (r < 0,10). Als statistisch signifikant erwiesen sich die Zusammenhänge zwischen Psychopathie und Kompetenzerwerb (p = 0,01, r = -0,23) sowie zwischen Psychopathie und Studienzufriedenheit (p = 0,03, r = -0,20).
Radioisotope-guided sentinel lymph node dissection (sLND) has shown high diagnostic reliability in prostate (PCa) and other cancers. To overcome the limitations of the radioactive tracers, magnetometer-guided sLND using superparamagnetic iron oxide nanoparticles (SPIONs) has been successfully used in PCa. This prospective study (SentiMag Pro II, DRKS00007671) determined the diagnostic accuracy of magnetometer-guided sLND in intermediate- and high-risk PCa. Fifty intermediate- or high-risk PCa patients (prostate-specific antigen (PSA) >= 10 ng/mL and/or Gleason score >= 7; median PSA 10.8 ng/mL, IQR 7.4–19.2 ng/mL) were enrolled. After the intraprostatic SPIONs injection a day earlier, patients underwent magnetometer-guided sLND and extended lymph node dissection (eLND, followed by radical prostatectomy. SLNs were detected in in vivo and in ex vivo samples. Diagnostic accuracy of sLND was assessed using eLND as the reference. SLNs were detected in all patients (detection rate 100%), with 447 sentinel lymph nodes SLNs (median 9, IQR 6–12) being identified and 966 LNs (median 18, IQR 15–23) being removed. Thirty-six percent (18/50) of patients had LN metastases (median 2, IQR 1–3). Magnetometer-guided sLND had 100% sensitivity, 97.0% specificity, 94.4% positive predictive value, 100% negative predictive value, 0.0% false negative rate, and 3.0% additional diagnostic value (LN metastases only in SLNs outside the eLND template). In vivo, one positive SLN/LN-positive patient was missed, resulting in a sensitivity of 94.4%. In conclusion, this new magnetic sentinel procedure has high accuracy for nodal staging in intermediate- and high-risk PCa. The reliability of intraoperative SLN detection using this magnetometer system requires verification in further multicentric studies.
Systematizing IT Risks
(2019)
IT risks — risks associated with the operation or use of information technology — have taken on great importance in business, and IT risk management is accordingly important in the science and practice of information management. Therefore, it is necessary to systematize IT risks in order to plan, manage and control for different risk-specific measures. In order to choose and implement suitable measures for managing IT risks, effect-based and causebased procedures are necessary. These procedures are explained in detail for IT security risks because of their special importance.
Hadoop is a Java-based open source programming framework, which supports the processing and storage of large volumes of data sets in a distributed computing environment. On the other hand, an overwhelming majority of organizations are moving their big data processing and storing to the cloud to take advantage of cost reduction – the cloud eliminates the need for investing heavily in infrastructures, which may or may not be used by organizations. This paper shows how organizations can alleviate some of the obstacles faced when trying to make Hadoop run in the cloud.
Nowadays, REST is the most dominant architectural style of choice at least for newly created web services. So called RESTfulness is thus really a catchword for web application, which aim to expose parts of their functionality as RESTful web services. But are those web services RESTful indeed? This paper examines the RESTfulness of ten popular RESTful APIs (including Twitter and PayPal). For this examination, the paper defines REST, its characteristics as well as its pros and cons. Furthermore, Richardson's Maturity Model is shown and utilized to analyse those selected APIs regarding their RESTfulness. As an example, a simple, RESTful web service is provided as well.
Our work is motivated primarily by the lack of standardization in the area of Event Processing Network (EPN) models. We identify general requirements for such models. These requirements encompass the possibility to describe events in the real world, to establish temporal and causal relationships among the events, to aggregate the events, to organize the events into a hierarchy, to categorize the events into simple or complex, to create an EPN model in an easy and simple way and to use that model ad hoc. As the major contribution, this paper applies the identified requirements to the RuleCore model.
Aim/Purpose: We explore impressions and experiences of Information Systems graduates during their first years of employment in the IT field. The results help to understand work satisfaction, career ambition, and motivation of junior employees. This way, the attractiveness of working in the field of IS can be increased and the shortage of junior employees reduced.
Background: Currently IT professions are characterized by terms such as “shortage of professionals” and “shortage of junior employees”. To attract more people to work in IT detailed knowledge about experiences of junior employees is necessary.
Methodology: Data from a large survey of 193 graduates of the degree program “Information Systems” at University of Applied Sciences and Arts Hannover (Germany) show characteristics of their professional life like work satisfaction, motivation, career ambition, satisfaction with opportunities, development and career advancement, satisfaction with work-life balance. It is also asked whether men and women gain the same experiences when entering the job market and have the same perceptions.
Findings: The participants were highly satisfied with their work, but limitations or restrictions due to gender are noteworthy.
Recommendations for Practitioners: The results provide information on how human resource policies can make IT professions more attractive and thus convince graduates to seek jobs in the field. For instance, improving the balance between work and various areas of private life seems promising. Also, restrictions with respect to the work climate and improving communication along several dimensions need to be considered.
Future Research: More detailed research on ambition and achievement is necessary to understand gender differences.
