No full textFrom Core Business to By-product : Why German Media Companies Still Invest in Journalism
Get PDFThe emergence of digital technologies over the past two decades has brought about changes that threaten the very existence of german media companies. The journalistic business model is losing sales, and the decline in print circulations is making it successively difficult to earn money with journalistic products. Therefore, german media companies have been investing in business models that have no relation to journalism to generate growth for years – with success. Considering this development, it is astonishing from a purely economic perspective that media groups, which are increasingly developing into technology companies, are still clinging to the ailing journalistic business model at all. To examine their motives to do so, this study poses the following research question: "Why do media companies still invest in journalistic products today?" To answer it, the researcher conducted interviews with highlevel employees from media companies as part of a qualitative study. Analysis of the data revealed that media companies continue to invest in journalism mainly because they benefit economically from the brands their journalistic products represent. Other reasons like serving as a pillar of the democratic constitution or to help shape public discourse seem to be less important

No full textEffect of Electrolyte pH in Additive-Free NiFe Catalyst Electrodeposition for Electro-Catalytic OER Applications
No full textThis study presents the correlation between electrolyte pH, surface morphology, chemical speciation and electro-catalytic oxygen evolution activity of additive-free electrodeposited NiFe catalysts for application in anion exchange membrane water electrolysis. Spherical morphologies were identified at pH 0, shifting towards honey-combed structures at pH 4 with increasing surface area, especially at pH 3. Further, the electrolyte pH was found to influence the NiFe composition and electro-catalytic activity. Enhanced OER activity was noted at pH 2 with overpotentials of 214 mV at 10 mA cm−2 and 267 mV at 100 mA cm−2. The results reveal that the electrolyte pH is a parameter not only influencing the morphology but also tailoring the surface area, Fe oxide and Fe hydroxide composition and consequently the catalytic activity. Further, the outcomes highlight the electrolyte pH as a key process parameter that should be adjusted according to the application, and may substitute the addition of electrolyte-additives, proposing a simpler method for improving catalyst electrodeposition
Impact of hBN Content on the Tribological Behavior and Thermal Diffusivity of HVOF-Sprayed Cr3C2-NiCr Coatings
No full textConsidering the significant health risks posed by hard chrome plating during its application, thermally sprayed Cr3C2-NiCr cermet coatings represent a suitable alternative. Incorporating hexagonal boron nitride (hBN) as a dry lubricant into the feedstock powder can further enhance wear resistance and thermal conductivity, crucial for preventing premature failure caused by inadequate lubrication. In this study, the mass fraction of hBN was varied between 0 and 15 wt.% to assess its influence on the tribological performance of the coatings using pin-on-disk tests. The coating’s hardness was measured via the Vickers method, and its cracking tendency at the coating/substrate interface was evaluated. Scanning electron microscopy (SEM) and X-ray diffraction (XRD) were employed to analyze the microstructure and phase composition, while thermal diffusivity was determined using the laser flash method. The findings revealed that the inclusion of hBN, at concentrations of up to 10 wt.%, leads to an improvement in thermal diffusivity and a reduction in the coefficient of friction. However, exceeding this threshold leads to a decrease in hardness and increased crack formation tendency, highlighting the trade-off between frictional and mechanical properties
Toolbox. Werkzeuge zur Sichtbarmachung von Innovatorinnen in regionalen Innovationskontexten
No full textMit der hier vorliegenden Toolbox stellen wir die Ergebnisse des dreijährigen, durch das Bundesministerium für Bildung und Forschung geförderten, Forschungsprojektes „Westfälische Erfinderinnen“ vor. Das Hauptziel des Projektes umfasste dabei, in den Regionen Ruhrgebiet und Münsterland Innovatorinnen zu identifizieren und die regionalen Mechanismen der (Un-)Sichtbarkeit von Innovatorinnen zu untersuchen und zu verstehen. Aufbauend auf den gewonnenen Erkenntnissen wurden ausgewählte Innovatorinnen zielgerichtet mit unterschiedlichen Kommunikationswerkzeugen ins Licht der regionalen Öffentlichkeit gerückt, um so das gesellschaftliche Bewusstsein für die Vielfalt von Innovationsprozessen und die Rolle von Innovatorinnen zu stärken. Die hier vorliegende Toolbox soll Hochschulen und andere zentrale Akteur:innen in weiteren Regionen ermutigen und anleiten, ihre Innovatorinnen zu finden, zu unterstützen und weithin
sichtbar zu machen
The Effects of Formal and Informal Institutions on Women’s Entrepreneurship in Georgia
No full textThe aim of this chapter is to address the impact of formal and informal institutions on women’s entrepreneurship and to extend our understanding of issues influencing women-owned businesses and women’s entrepreneurship in the context of a transition economy, such as Georgia. Our work specifically addresses formal institutions, such as governmental initiatives, financial institutions, and business-relevant education. It also addresses informal institutions, such as women’s role in society, the use of informal networks of connections and acquaintances, and gift-giving practices. Drawing on results from an online focus group discussion with women entrepreneurs in Georgia, we provide initial insights into the critical constraints and supporting factors that local women entrepreneurs experience. Based on the interrelation of institutions and women’s entrepreneurship, we conclude that changes in formal institutions do not lead directly to changing informal institutions. Due to the lack of trust in formal institutions, women entrepreneurs are more likely to look for business development solutions outside the official frames, including illegal or unethical means of survival. Nevertheless, increased opportunities – induced by specific entrepreneurship policies and programs – encourage women to enter entrepreneurship. In addition to this, entrepreneurship enables women in Georgia to overcome gender discrimination issues, which is more prevalent in employment relationships in the local labor market than in entrepreneurial activities
Interaction of Robot Speed and Distance in Human-Robot Collaboration: Impact on Human Trust, Safety, and Comfort
No full textAbstract
Robots are gradually being freed from their safety fences due to the advances in safety features integrated with most new robots. These robots enable a new form of human-robot interaction in which contact is possible. There are two robot-related factors that play a decisive role in the interaction dynamics and human perception in such a case - the motion speed and distance the robot keeps away from the human. Literature indicates that these factors influence whether humans perceive trust, safety, and comfort, which are essential components in the acceptance of robots by their end users. However, although speed and distance were intensively investigated in isolation, little is known about their combined effect. To this end, we conducted an experiment investigating the impact of the industrial robot arm’s approaching speed and stopping distance on the users’ trust, safety, and comfort while they were performing a collaborative task. Our results provide interesting insights into the implications of speed and trust. While we were able to replicate former studies in terms of implications of speed and distance, our data does not show any interaction effect between the two variables. However, our participants’ observations indicated that distance impacts the dependent variables more severely than speed
Towards Privacy-friendly Telepresence Robots for Schoolchildren with Long-term Illnesses – User Needs of Relevant User Groups
No full textAbstract
Remote participation in school is possible today with the help of telepresence robots. Such technologies can offer great opportunities for children with long-term illnesses to continue attending school. Consequently, telepresence robots are already used in some schools when children are absent for long periods. However, despite their positive impact, such robots also create challenges for the privacy of people involved in such a setting. Therefore, in this paper, we discuss the user needs of such robots in this specific and privacy-sensitive application field. We held three workshops with different user groups with and without experience with the robots. Among them were formerly and currently ill children, parents, teachers, head teachers, media educators, and supporting personnel. We discussed their experiences (if any), ideas, expectations, and concerns with a focus on privacy aspects to find out about the user needs of different user groups. Our results reveal various interrelationships and conflicts between the individual actors. They serve as a basis to discuss the implications for the design of future telepresence robots for schoolchildren
