Due to the present developments of the Internet and its technical components, the skills of the web experts have to be more and more complex and specific. The Internet experts in the creative field are located distributedly around the whole world. As a result, many companies have problems to find the needed experts on site and are dependent on creative cooperations and virtual teams with the help of technical tools. The virtual working place is an important issue, particularly in modern times and the market offers more and more cooperation systems for exactly this purpose: Creative cooperation in distributed working situations. This thesis examines the approaches of creative cooperation and cooperation technologies with an analysis about existing cooperation systems with a creative context. It spans a wide range of tools. On the one hand, there are approaches which offer only straightforward solutions for single design tasks. On the other hand, there are providers which recognised the great need of creative cooperation systems and working at full speed to extend their systems. The examined areas of this work lead to a design process oriented approach with flexible frames and enough space for the creative development of every single user. The cooperation in a creative context stays in the foreground and is the base for future approaches for the web design sector.
Since the development of eGovernment systems is gaining worldwide momentum, the European Union is constantly increasing its efforts to induce the development of eGovernment systems in its member states. The currently running strategy is the ’eGovernment Action Plan 2016-2020’, which understands itself as a catalyst for developments in the member states.
Despite these ongoing efforts by the European Union regarding eGovernment, stud- ies are repeatedly revealing that the quality and acceptance by the citizens of dig- ital public services are varying heavily within the EU. Being based on the same political guidelines provided by the EU, the national strategies implemented the core principles to different degrees. These different implementation rates, analyzed for Germany, the United Kingdom and Estonia, supplement the holistic analysis of the eGovernment policies, applications and usage in each member state. This gets proven by the connection of this indicator with related studies in the field of eGov- ernment applications and usage within the European Union.
The aim of this thesis is, on the one hand, to quantify differences in the implementa- tion of the ’eGovernment Action Plan 2016-2020’ into national policies in Germany, the UK and Estonia and, on the other hand, establish this indicator as a valuable asset for evaluating and monitoring the eGovernment efforts by the EU member states.
This paper is grounded in the emerging field of web science and shall contribute to its further classification and demarcation by illustrating the current state of »web-native research methods«. It builds upon an initial arraying work of Richard Rogers, who coined the term »Digital Methods« for research with methods that were »born« in the web, and illustrated and organized them in his eponymous book in 2013. This paper attempts to develop a more appropriate illustration of the Digital Methods by following the web’s very own, hypertextual, network-like nature, in particular by construing an ontological representation on the base of the Web Ontology Language (OWL). By virtue of decomposing the book into granular information units and their subsequent reassembly into OWL entities, immediate access to the entire knowledge domain can be provided, and coherencies, interrelations and distinctions between concepts become apparent. The ontology’s structure was induced narrowly along the provided examples of research projects and subsequently clustered in topic groups, of which the three most important ones were (a) the Digital Methods as an arraying space of web-native methodology, (b) a collection of concrete applications of these Digital Methods in research projects, and (c) a hierarchical scheme of traditional sciences with a distinct interest in answering research questions with help of Digital Methods. Subsequently, the ontology was evaluated in three general dimensions: Deriving user stories and scenarios provided means to validate the utilization quality; the accuracy and reliability of the resulting structure was validated with help of a control group of web-native research projects; and process control instruments served as a validator for the ontology’s correctness. Despite the ontology itself, this paper also resulted in a first interpretation of the produced information: Statements about research practise in social science, politics and philosophy were as possible as findings about commonly applied varieties of methods. Concluding, the present paper proposes a process of ontology engineering, an evaluation of the ontology’s value, and an interpretation of the ontology’s content.
This thesis proposes four different Augmented Reality (AR) display techniques that can overcome the problem of uncertain tracking errors. Where most other papers focus on limiting the amount of error that a user tracking system generates, this paper pro-poses visualizations that limit their impact instead. For this, four different display techniques have been developed and evaluated using criteria found in related literate. Two of the four proposed solutions consistently ranked better within these criteria. The first, Bending Words, uses a mix between spatially registered information and turn instructions to achieve that result. The second, WIM, mostly relies on context infor-mation of the building instead.
Usage of smart home solutions implies generation, processing, and storage of machine and personal data. Recently made public cases of data breaches and misuse increased peoples’ concerns of data security and decreased the trust in secure data handling and smart home technologies. Hence potential benefits are not exploited. It is therefore necessary to analyse how manufacturers can increase their online trust perception.
Requirements of (potential) customers of web based services for HVAC systems are identified using thematic analysis for 23 conducted interviews using online trust perception literature as basis. Manufacturer independent websites are derived as the most important online touch point for customers with manufacturers and products. Determined content and structure measures for online touch points managed by manufacturers derived to positively influence the manufacturer and manufacturer independent touch points regarding perception of trust. The derived trust concept must be evaluated in the following using the defined evaluation plan.
This bachelor thesis deals with framework-agnostic design systems in the environment of micro frontends. The properties of micro frontends and design systems are developed individually, to finally get combined. Important disciplines of this research are in particular cybernetics and system thinking, whereby further properties in the relationships between the stakeholders and the design system are highlighted and defined. In addition, based on the highlighted properties, a practically oriented evaluation is prepared, which demonstratively verifies how framework-agnostic design systems can be realized using Svelte and Tailwind CSS. The insights gained from this work can be used for further considerations in other works within the domain, or similar domains. In particular the cybernetic view of systematic design offers potential for further investigations.
Speedrunning in general means to go fast in a video game. This simple concept has an immense impact on the ways players engage with games. The inherent aspect of optimization within this esports niche makes it a good application field of optimization methods. This work gives an overview of speedrunning as an esports discipline. Prior works on this subject are discussed and assessed and relevant nomenclature is introduced. Using this information, routing --- the procedure of planning a speedrun --- is picked up as a graph optimization problem.
Nintendo's iconic game The Legend of Zelda: Ocarina of Time from 1998 is used as a working example to assess previous works and to explore more of this mainly uncharted field of research.To do so, the process of speedrun modeling is conducted as exhaustive as possible within the limits of a work like this. All relevant steps to obtain a faithful model are lined out. This procedure yields a partial game graph with 6764 nodes and approx. 321,022 edges --- some uncertainty included. Current pathfinding techniques are discussed and assessed regarding their applicability to the presented speedrun routing problem. The resulting graph model and algorithmic approaches present a good reference to identify the most promising points of improvement. Challenges, flaws and possible solutions to still standing problems are discussed and assumptions from prior works are assessed. Finally, further tracks of scholarly and community work in this area are suggested and possible extensions to the approach are lined out.
It is shown that speedrun routing is not a trivial shortest path problem that can be solved with conventional methods. Furthermore, it is made clear that different games can have vastly differing routing circumstances. Assumptions of other works have been assessed using a working example and many interesting challenges and fields of further study and research in the field of speedrunning have been identified. Some probabilistic pathfinding methods and current works on AI agents for games pose interesting approaches which can be extended on by utilizing the findings of the presented work. Specialized modeling and optimization techniques have to be employed in order to have a positive effect on the speedrunning community.
Digital competences are describing a set of skills, which are necessary to use digital devices and tools with an adequate degree of self-determination. With the ubiquitous digitization of our lives and our society it is important for every citizen to have digital competences. Therefor, it is necessary to educate those competences in schools. As one cannot assume teachers to have enough digital competences to well educate the children of todays classes, this master thesis tries to find out: How to shape the process of teaching digital competences to adolescents in German schools, focusing on including multiple parties from diverse backgrounds into the process? At first, the current situation of teaching digital competences in German schools is analyzed by means of a literature review. After the identification of the challenges within the German system, international best practices are examined. Therefor, four countries, which have reached high scores in the International Computer and Information Literacy Study are selected. Australia, the Czech Republic, Denmark and the Republic of Korea are compared and possible chances for Germany identified. As the next step, expert interviews with divers parties, which have direct or indirect relation to the German education system, are held. The goal of the interviews is to generate ideas on how to support the education system by external help. At the end of the thesis the recommended approach of Motivating External People is presented. Several measures, such as teaching or mentoring students in a guest lecturer model; providing IT support for the hard- and software of the schools or creating Open Educational Resources as education material for the teachers are presented and possible third parties are named. As it is not possible to support the education system from the outside without education system internal persons, it is presented, what needs to change within the system to get the approach working. Therefor, not a complex and system changing approach is presented, but a combined top-down and bottom-up process to motivate external people to support.
There is a dramatic shift in credit card fraud from the offline to the online world. Large online retailers have tried to establish countermeasures and transaction data analysis technologies to lower the rate of fraudulent transactions to a manageable amount. But as retailers will always have to make a trade-off between the performance of the transaction processing, the usability of the web shop, and the overall security of it, one can assume that e-commerce fraud will still happen in the future. Thus, retailers have to collaborate with relevant business partners on the incident to find a common ground and take coordinated (legal) actions against it.
Trying to combine the information from different stakeholders will face issues due to different wordings and data formats, competing incentives of the stakeholders to participate on information sharing, as well as possible sharing restrictions that prevent them from making the information available to a larger audience. Moreover, as some of the information might be confidential or business-critical to at least one of the parties involved, a centralized system (e.g. a service in the public cloud) can not be used.
This Master Thesis is therefore analysing how far a computer supported collaborative work system based on peer-to-peer communication and Semantic Web technologies can improve the efficiency and effectivity of e-commerce fraud investigations within an inter-institutional team.
Blogging has established itself as an important and influential part of the
modern online media. At the dawn of the blogosphere people were publishing
their diaries and life journals. Nowadays, some bloggers operate blogs that are
hardly any different from online newspapers and magazines. On the one hand
professional blogging is broadly accepted in the society, but on the other hand
it is poorly understood. The purpose of this explorative study is to broaden
the understanding of blogging as a professional activity. In particular, this
study explores the aspects of professional blogging and the interplay between
credibility, authenticity and monetisation in blogs.
To understand blogging as a professional activity an extensive literature
research is conducted. First, main concepts of blogging as a social activity
are discussed. Then, the changes that come together with the transformation
of a social activity into a professional activity of blogging are discussed. To
look at the activity of blogging from an unusual perspective, a comprehensive
qualitative survey is conducted with blog readers. The survey examines
not only readers’ perception of blogging as a professional activity, but also
motivations for reading blogs and attitude to monetising practices and labelling
of monetised content in blogs. Information received from the survey is used to
draw some conclusions about the state of the art of blogging as a professional
activity, and challenges and opportunities blogging industry faces nowadays.
