Abstract
Communication with remote persons over a video link is common today, e.g. to connect with family members abroad, particularly during the COVID-19 pandemic. However, social activities such as board games are rarely shared in this way, as common video chat software does not support this scenario well. However, interactive tabletops provide inherent support for natural tangible interaction with items on the tabletop surface.We present the Tabletop Teleporter, a setup designed to merge two remote locations into a single shared interaction space. We evaluate the system using a board game, focusing on the perceived immersion and connectedness of participants. Our evaluation shows that most measures for the social quality of a remotely shared game are not significantly different from one played with co-located participants, and that players prefer our setup over a pure videochat scenario.

Abstract
Within the past ten to fifteen years the concept of Employer Branding (EB) has established itself as a widely known and highly regarded concept especially among Human Resource Management practitioners. In many organizations the development, implementation and communication of a distinctive and unique employer brand is meanwhile considered an important building block for gaining a competitive advantage in the so called “war for talent”. The paper at hand aims at critically exploring the conceptual foundations of employer branding by reviewing an extensive body of EB-literature consisting of standard references, scientific journal articles, textbooks as well as practitioner-oriented literature. This review reveals several general weaknesses, discrepancies and “blind spots” which cannot simply be attributed to some few single publications but rather call for a skeptical look upon the whole concept of employer branding itself. In conclusion the authors assert that the employer branding concept widely lacks innovative novelty as well as content-related persuasiveness. It should therefore be regarded as neither more nor less than a contemporary remake of what is and has for quite some time been well known as “Internal Marketing” or “HR Marketing”.

Abstract
Within assembly network supply chains, supply disruptions can occur on every supplier-buyer link. Managing this network unreliability can help to reduce schedule instability and increases the overall efficiency of the supply chain accordingly. In this line, a stylised assembly network supply chain model is proposed with two suppliers and a single buyer using the joint economic lot sizing approach. This supply network can be disrupted by a shortage occurring at one of the two suppliers due to random machine breakdowns, which consequently creates dependent requirements variations affecting both the buyer and the entire network. First, the basic joint economic lot sizing model is extended by the said schedule instability. Second, a solution approach is presented concerning the determination of optimal lot sizes, the investment into the reliability of the supply network as well as the determination of safety stocks. Furthermore, the sensitivity of relevant model parameters is investigated by means of a numerical example. Managerial implications are accordingly derived focusing on the reliability of the supply network members and internal incentive structures.

Abstract
Recent studies have shown a number of procedural similarities between solving problems in mental and in physical rotation. Such similarities open up the interesting option to study mental rotation indirectly through physical rotation, with the advantage that physical rotation processes can be much more easily observed than mental ones. To better assess where solution processes in mental and physical rotation differ, though, it is important to know what influence any specific interaction method in physical rotation will have. We present results from a comparison of two such interaction methods: a one-handed, touch-based and a two-handed, ball-based method. Our analysis focuses on fixation durations and saccade amplitudes as proxies for mental load. Results show, importantly, that the choice of interaction method seems to matter but little. We therefore suggest that the existing findings of past studies that have compared mental to physical rotation are likely highly comparable, despite the fact that different interaction techniques were used.
