The master thesis introduces a new conceptual model for the design of web technology based on the concepts of worth and values. Using the holistic perspective of Web Science, the model not only takes users’ needs into account but also the demands of their social and cultural environment in order to facilitate the creation of better, more successful, as well as more responsible systems.
Since web technologies change and shape the world profoundly, it is important to take the positive and negative consequences into account that new systems might have for the environments in which they are embedded. The work investigates on a conceptual level how a relevant design approach that builds on the idea of making worth and values a main concern for the development of computer technology can be put into practice.
Worth, value, and values
First, the abstract concepts of worth, value and values are illuminated. Although these terms are frequently used in literature they are hardly defined and not used in a consistent way. Therefore, definitions are given followed by a conceptualization. Further, it is shown in which dimensions values generally can reside in order to provide guidance for their identification. On a high level there are economic, social, cultural, political, ecological as well as moral and ethical value dimensions that may all be potentially relevant in a design case. This diversity illustrates that an interdisciplinary approach is needed when values are concerned in design. The first part of the thesis ends with a demonstration on how values come to life in computer technology. By means of examples it is illustrated that values reside on every technical level in ICT and it is argued that technology is always value-laden no matter whether values have been an explicit concern in the development process or not.
Values- or worth-oriented design methodologies
The second part of the thesis presents the results of a literature research about existing values- or worth-oriented design methodologies.Â Here, a couple of approaches were found, which differ in their perspectives and main priorities and which have different theoretical and practical substance. Overall, Value Sensitive Design (VSD) , Designing Worth (DW) [1,2] and Participatory Design (PD)  were identified as sophisticated methodologies that offer enough substance to be put into practice and to which many other approaches can be referred to. Each approach has a specific emphasis and it was found that none of them covers all aspects relevant to put a holistic worth- or values-oriented design of web technology into practice.
Comparing key principles
In the third chapter, a comparison of the approachesâ key principles is made, which illustrates relationships, overlaps, and differences of the approaches in a systematic way. Finally, a new conceptual design model is introduced, based on the idea to combine the elements from PD, DW and VSD into a new approach that can fill the gaps and shortcomings of the individual methodologies and thus brings designing for worth and values one step further.
Conceptual Approach with a Focus on Worth and Values
The proposed design model builds on the Worth Development Framework from Cockton  but is enhanced by a further process and refined by the inclusion of resources like Worth Maps and Value Stories.
Thereafter, the design work is divided into five processes: Understanding for the pre-determination of human values, Opportunity Identification for the identification of stakeholders and values elicitation, Design and Evaluation that are closely intertwined and performed concurrently and, finally, Iteration that investigates design defects by causal analysis and determines targets for iteration. The practical design work is dominated by methods, tools and techniques from PD, which are well suited to elicit abstract and subjective values and worth and therefore represent the heart of the approach. VSD contributes with a focus on human values with ethical support and the stakeholder concept.
How far the proposed approach will work in practice has still to be proven. Nevertheless, it is a proposal which is theoretically founded on contemporary research and therefore it seems to be feasible and promising. At least, it contributes to the ongoing discourse and further advancement in the development of such web technologies that are not limited to the fulfilment of narrow and short-sighted interests but instead facilitates to create smarter, more successful and sustainable as well as responsible systems and thus helps to create a Web we want.

Research methods: There is so much to love about them, for example that they can guide you in a systematic way to find an answer to your research question. As a master student, it can however be pretty frustrating. For example,Â when your lecturer asks you to come up with a research design for a problem you just started to think about, including the selection of appropriate methods, which you maybe just have learned about the other week in a lecture.
Research approaches and methods are often presented in a quite abstract or brief way, especially when you read articles published in conference proceedings, as the authors have to adhere to the page limitations. There are many excellent books on research methods, but maybe an even more fun way to learn about research studies, their design, the used methods and the findings is to listen to the researchers talking about it in podcasts.
One of my favorite Podcasts is You Are Not So Smart by David McRaney. In his blog and podcast, he explores “self delusion” and the central theme of his podcast is “that you are unaware of how unaware you are”. In the very first episode, he talks about “attention” and interviews Daniel Simons, one of the researchers behind the Monkey Business Illusion, which you might have seen before. For me, it is super interesting to listen to the researchers explaining what happened behind the scenes, in other words how they set up their experiments or studies, their rationales behind it, and what they found. At the end of each podcast âthere will be cookiesâ and an read-out abstract from a related study.
The podcast is really great and I personally learned a lot about many phenomena. Take for example the backfire effect (episode 93-95), which is highly relevant also in relation to “fake news” and other issues we face today. I listened to all episodes by now and highly recommend to start with the first episode. By listening to them, not only will you learn specific aspects about certain phenomena, but also increase your general knowledge about research, research methods, the language researchers use to explain what they do (i.e., the specific terms used), how a research design might be set up, things to consider and so on.
I recently came across the 6029521708 which is described as “A podcast by scientists, for scientists. Methodology, scientific life, and bad language. Co-hosted by Dr. Dan Quintana and Dr. James Heathers”. I listened to episode 46, because here they interview Andy Field. Andy is the author of the (912) 228-3713 and – no kidding – a science fiction novel on statistics. The latter is on my pile of books that are yet to read for far too long:

As Andy Field says in the podcast, everyone has to find the resources that speaks to them. So his books may not be for you; I personally like his writing style and used his books when preparing my lecture on research methods. So whatever you choose, as soon as you start reading research papers, books on research methods, or listening to podcasts talking about research, you might realize that there is a lot to think about before carrying out a study.Â InÂ line with David McRaney’s theme: You don’t know, what you don’t know. So why not give it a try and start making use of those podcasts?
The conceptual model was tested using two qualitative research methods namely: Observation and Interviews to carry out the study. The Observation phase was carried out over a period of five (5) days at a canteen in Munich, whereby the mode of payments of an average of one hundred and twenty (120) people were observed daily. Afterwhich, interviews were conducted to enable the researcher ascertain the factors that influence the intention to use and adopt mobile payments.
During the study, it was revealed that Data Privacy and Security were the core factors that would influence the intension to use mobile payments. Interestingly cost was an additional factor that also impacted the user’s perception on usefulnesses which was derived by comparing the value added offerings and associated cost to existing alternatives.
Due to the sample size, there were some limitations based on the location and the fact that most participants interviewed were male, thereby social factors such as the influence of gender could not be explored. However, two core external factors beyond the control of the end user were identified as the major challenges facing the adoption of mobile payments in Germany. (1) The inexistent support and specification standards for mobile payments by the domestic network known as girocard and (2) the poor acceptance by merchants. A strategic collaboration among stakeholders of the payment industry will be required if mobile payments is to be successful in Germany. The average end user must be confident enough to visit any merchant without the fear of limited acceptance for contactless payments
Web Science Graduate Cagdas Cumhur ÃnlÃ¼er received the first price of the Opitz Innovation Award for his Master Thesis “Characteristics for intelligent food packages and Internet of Things solutions based on conditions for food waste in Germany”. In his Thesis Cagdas Cumhur ÃnlÃ¼er designed an IoT approach for a reduction of food waste. The general idea of deploying intelligent food packages is founded on quantity structures and well defined technical and economical concepts.

Did you ever think about getting back to University to earnÂ your Master of Science? Lifelong learning is essential, especially in a world that is constantly changing. Then some questions might come up: But what about my job? Where would I live and how would I be able to pay for this? Okay, there may be some online programmes, but a) how credible are these and b) would I really be motivated to learn all this on my own as self-study?
We designed our Master programme in Web Science so that you would neither have to quit your job nor have to move. It is designed for students, who work full-time and want to pursue their Master of Science degree in part-time.
To make this feasible, the programme is mainly held online, but we start and end each semester with an on-site weekend. During the first weekend, lectures are held and project teams are formed. And as we heard, the students meet in the evenings and exchange experiences and get to know each other. This is also very important as during the semester most of the students will mainly meet online whenÂ working together in their projects.
During the semester, every Tuesday and Thursday online sessions for the courses are held in the evenings (19.00 – 22.00 o’clock). Often the students have to prepare some small exercises in advance, read specific literature, or watch online lectures. In that way, the online sessions can be highly interactive, where students e.g. work together in smaller groups on a given task, which is then discussed in class together with the lecturer. This makes it possible for students to apply directly what they learned, engage in discussions (which also supports deeper understanding), and get immediate feedback. In modules which include a project these online sessions are also used to discuss the progress, challenges and opportunities of the project. Individual feedback is very important, so that the students can improve their project constantly throughout the semester. Interactive sessions, working together in groups, engaging in discussions and receiving individual feedback is something that differentiates the Web Science Programme from others online programmes in which students mainly have to study on their own. Self-study may not be that motivating and when there is increased stress at work, it may be very tempting to postpone it. Like the membership in the gym, where you for sure start practicing again next week ð .Â We can see that the students in our programme are highly motivated, work really well together, and help each other.
During the last weekend in each semester, the second on-site meeting is held. Here, the students will have their exams, which can be a written exam or a project presentation. It is always exciting; not only due to the exams, but also to see the final results of the often very interesting projects.
So what about the “But, …” questions mentioned at the beginning? I think we addressed these in our programme:
You can keep your job and thus won’t loose your income. You wouldn’t have to move, because we only have two on-site weekends per semester, so for most students it is feasible to travel for those weekends to Cologne.
Our programme has be examined by the independent and professional agency (859) 312-6641. The accreditation of our Web Science Master programme has been successfully renewed until 2023.
Although you may have to work on some exercises or read literature on your own, you mostly have meetings together with peers or work in teams, which makes it easier to focus and to stay motivated.
So, what are you waiting for? 972-296-6028
The Masters programme âWeb Scienceâ at the Cologne University of Applied Sciences (TH KÃ¶ln) covers in this year’sÂ Advanced Seminar (/webscience.th-koeln.de/smwiki/index.php?title=Advanced_Seminar) a broad and challenging spectrum of topics: Social Media are kind of an umbrella for more detailed coverage of aspects like user behaviour, governance, security, and privacy. Great research contributions could be discovered at conferences like the acm Web Science Conference (/www.websci16.org) or the World Wide Web Conference (/www.www2017.com.au).
The Advanced Seminar is part of the module âWeb Project Developmentâ in the online extraoccupational Masters programme ((505) 276-4546). The seminar is held with frequent discussions and cooperations online in the evenings during the semester, and a poster session on a Saturday in July in Cologne (SÃ¼dstadt) ending the semester work.
