• Much Ado About Little: A Critical Review of the Employer Branding Concept

  Behrends, T. ., Baur, M. ., & Zierke, L. . (2020). Much Ado About Little: A Critical Review of the Employer Branding Concept. In (S. 1–30). Baden-Baden: Nomos Verlagsgesellschaft mbH & Co. KG. http://doi.org/10.5771/0935-9915-2020-1-1

  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”.

• Managing unreliability in automotive supply networks – an extension of the joint economic lot size model

  Gruchmann, T. ., & Brandenburg, M. . (2020). Managing unreliability in automotive supply networks – an extension of the joint economic lot size model. International Journal of Operational Research, 39(1). http://doi.org/10.1504/IJOR.2020.108838

  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.

• Comparing Eye Movements Between Physical Rotation Interaction Techniques

  Bertel, S. ., & Wetzel, S. . (2020). Comparing Eye Movements Between Physical Rotation Interaction Techniques. In ACM Symposium on Eye Tracking Research and Applications. New York, NY, USA: Association for Computing Machinery. http://doi.org/10.1145/3379156.3391355

  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.

• Untersuchung von opensource Datenbanksystemen auf Härtungsmaßnahmen unter Betrachtung des BSI IT-Grundschutz-Kompendium

  Die Relevanz von Opensource Software (OSS) steigt immer weiter an. Laut einer Studie der Bitkom setzen heutzutage 69% aller Unternehmen, bewusst OSS ein und bis zu 75% der Unternehmen planen OSS einzusetzen [1]. Gleichzeitig steigt die Gefahr von Angriffen auf moderne Technologien [2]. Datenbanksysteme (DBS) stehen heute schon auf Platz 4 der am häufigsten angegriffenen IT-Systeme [3]. Die Wichtigkeit von Daten im heutigen Zeitalter steigt noch immer weiter man, somit ist eine noch höhere Angriffswahrscheinlichkeit auf DBS wahrscheinlich. In dieser Arbeit wurde die Umsetzbarkeit des Bausteins „APP.4.3 – Relationale Datenbanken“ des IT-Grundschutzkompendium der Bundesagentur für Sicherheit in der Informationstechnik (BSI) in den Opensource DBS Oracle MySQL, PostgreSQL und MongoDB untersucht. Die drei gewählten Systeme sind die derzeit am meist verbreiteten Opensource Datenbanksysteme und bedürfen daher erhöhte Aufmerksamkeit [4] [5]. Organisatorische Maßnahmen wurden anhand von Empfehlungen, Vorgaben und Beispielen erarbeitet. Technische Maßnahmen wurden nach Möglichkeit direkt in den DBS umgesetzt. Sofern keine interne Umsetzung notwendig war, wurden Opensource Erweiterungen von Drittanbietern gesucht und getestet. Anhand der vom BSI bereitgestellten Auditorencheckliste wurden die Maßnahmen bewertet. Organisatorische Maßnahmen wurden aus der Wertung herausgenommen. Es wurden die Punktekategorien 0 für gar nicht umsetzbar, 1 für teilweise umsetzbar und 2 für komplett umsetzbar vergeben. MySQL erreichte 73% der möglichen Punkte, PostgreSQL 67% und MongoDB 47%. Ein Großteil der notwendigen Funktionen wird vom Originalhersteller zwar bereitgestellt aber ist nur in der kommerziell verfügbaren Variante der Systeme aktivierbar. Abstract: The relevance of Open Source Software (OSS) is constantly increasing. According to a study by Bitkom, 69% of all companies today use OSS consciously and up to 75% of companies plan to use OSS [1]. At the same time the danger of attacks on modern technologies is increasing [2]. Database systems (DBS) are already in 4th place among the most frequently attacked IT systems [3]. The importance of data in today s age is still increasing, so an even higher probability of attack on DBS is likely. In this thesis the feasibility of the module ‚APP.4.3 - Relational Databases‘ of the IT basic protection compendium of the German Federal Agency for Information Security (BSI) was examined in the open source DBS Oracle MySQL, PostgreSQL and MongoDB. The three chosen systems are currently the most widespread open source database systems and therefore require special attention [4] [5]. Organisational requirements were developed on the basis of recommendations, specifications and examples. Where possible, technical requirements were implemented directly in the DBS. As far as no internal implementation was possible, open source extensions of third-party providers were searched and tested. The requirements were evaluated using the auditor checklist provided by the BSI. Organizational requirements were removed from the evaluation. The point categories 0 for not realizable at all, 1 for partially realizable and 2 for completely realizable were assigned. MySQL achieved 73% of the possible points, PostgreSQL 67% and MongoDB 47%. Most of the required functions are provided by the original manufacturer but can only be activated in the commercially available version of the systems.
