Stress beeinflusst verschiedene Kognitionen, wie zum Bespiel Lernen und Gedächtnisbildung/-abruf. Der Einfluss von Stress auf exekutive Funktionen ist erst in den letzten Jahren vermehrt untersucht worden. Diese Studien zeigen, dass akuter Stress das Arbeitsgedächtnis, kognitive Flexibilität und kognitive Inhibition negative beeinflusst, während Verhaltensinhibition durch Stress verbessert zu werden scheint. Bislang ist wenig über den Einfluss von Stress auf die zugrundelie- genden kognitiven Prozesse der Verhaltensinhibition bekannt. Um dies zu untersuchen wurden 55 gesunde junge Männer und Frauen zunächst dem sozialevaluativen Kaltwasserstresstest bzw. einer Kontrollbedingung mit warmen Wasser unterzogen und bearbeitet danach eine Go-Nogo-Aufgabe, während EEG und EKG aufgezeichnet wurden. Im Verlauf des Experiments wurden fünf Speichelproben abgegeben. Erste Analysen zeigen, dass akuter Stress die Verhaltensinhibition in Abhängigkeit der Stress-induzierten Cortisol-Konzentration beein- flusst. Versuchspersonen mit einem deutlichen Cortisolanstieg (> 2 nmol/l, Cortisol-high-responder) zeigten eine verbesserte Verhaltens- inhibition, während gestresste Versuchspersonen ohne nennenswer- ten Cortisolanstieg (Cortisol-low-responder) die schlechteste Leistung zeigten. Die Ergebnisse der EKPs bestätigen diesen Eindruck. Wäh- rend die Nogo N2 nur durch den akuten Stress moduliert wurde, zeigte die Nogo P3 Änderungen in Abhängigkeit der Stress- induzierten Cortisol-Konzentration. Diese Ergebnisse bestätigen bisherige Befunde zur verbesserten Verhaltensinhibition durch akuten Stress. Gleichzeitig deuten sie darauf hin, dass die zugrundeliegenden kognitiven Prozesse unter- schiedlich beeinflusst werden und dass Cortisol bei der Umverteilung kognitiver Ressourcen durch Stress entscheidend ist.

Innovative entrepreneurship is considered an important pillar for economic development and has sparked a lively discussion in academia and practice alike. Oftentimes, however, the debate is not sufficiently grounded on solid empirical evidence. The academic literature is growing but very scattered and is separated into several disciplines. We provide a summary that takes stock of the academic knowledge about innovative entrepreneurship and summarizes the evidence from 102 empirical studies published in the primary economics and management journals on the antecedents, behavior, and consequences of innovative entrepreneurship. Based on this state-of-the-art literature review, directions for future research are discussed. [less ▲]

Research indicates that individuals’ digital footprints, for example in Twitter and Facebook, can reveal remarkably valid information about their personality characteristics. In this study, we use digital footprints to gain insights into the personality of superstar entrepreneurs and managers, a largely understudied population in entrepreneurship research. Specifically, we compare the personality characteristics of 106 of the most influential business leaders employing a computerized text analysis tool based on the individuals’ Twitter messages (Receptiviti). Our findings are surprising and indicate that superstar managers are more entrepreneurial in many personality characteristics than superstar entrepreneurs. However, we also found some indications that superstar entrepreneurs seem to show features of a classic “Schumpeterian” entrepreneurial personality with respect to being creative, independent rule-breakers.

China has been experiencing a substantial growth in patent applications. But is this increase accompanied by a similar increase in patent value? To assess this question, we examine the citation lag of Chinese patents as a proxy of patent value in comparison with patents from the US, Europe, Japan, and Korea. Our empirical analysis comprises a unique data set of 60,000 patents with priority years between 2000 and 2010. Utilizing Cox regressions, our results show that Chinese patents suffer from a large citation lag in comparison to international patents, indicating a lower value. This is especially true for patents filed domestically. However, we find empirical support for an increasing patent value in more recent patents. China shows a strong dynamic in the field of patenting and our results suggest that the gap between Chinese patents and international patents might narrow down in the near future. [less ▲]

We analyse the initial IP applications of 4,703 start-ups in the U.S., distinguishing between trademark and patent applications. Our empirical results show that start-ups are more likely to file for trademarks instead of patents when entering markets with a higher market concentration. Furthermore, we find that start-ups that are primarily active in business-to-consumer markets instead of business-to-business markets are more likely to file trademarks. Finally, the involvement of a venture capitalist (VC) affects the initial IP application. VC-backed start-ups are more likely than other startups to file initial IP in the form of trademarks rather than patents. This paper contributes to research on the use of IP rights in start-ups and to the literature on new venture strategy. [less ▲]

Depuis une trentaine d’années, les signatures d'artistes du Moyen Âge font l'objet de recherches qui ont permis de mieux cerner la condition sociale de l'artiste à cette époque. Au sein de cette production scientifique, un aspect reste pourtant encore largement à explorer: celui de la connaissance et de la pratique de l'écrit de la part des producteurs d’images. En envisageant les signatures en tant que produits écrits, l’article insiste sur l’apport de cette documentation pour étudier le niveau de compétence graphique, voire de la connaissance du latin, des artistes au Moyen Âge central. Dans un premier temps, le postulat de l’analphabétisme intégral des artisans-scripteurs est discuté à la lumière des sources textuelles et des traces matérielles encore visibles sur les inscriptions conservées. Sont ensuite envisagées différentes situations de maîtrise graphique et linguistique permettant d’éclairer autant de degrés d’alphabétisation des artisans, qui invitent à nuancer l’opposition traditionnelle analphabète/lettré. Enfin, sont explorées les pistes de recherche possibles pour comprendre par quels biais la connaissance de l’écrit et du latin pouvait être acquise par les artistes à l’époque romane. [less ▲]

After decades of large-scale digitization, many historical newspaper collections are just one click away via online portals developed and supported by various public or private stakeholders. Initially offering access to full text search and facsimiles visualization only, historic newspaper user interfaces are increasingly integrating advanced exploration features based on the application of text mining tools to digitized sources. As gateways to enriched material, such interfaces are however not neutral and play a fundamental role in how users perceive historical sources, understand potential biases of upstream processes and benefit from the opportunities of datafication. What features can be found in current interfaces, and to what degree do interfaces adopt novel technologies? This paper presents a survey of interfaces for digitized historical newspapers with the aim of mapping the current state of the art and identifying recent trends with regard to content presentation, enrichment and user interaction. We devised 6 interface assessment criteria and reviewed twenty-four interfaces based on ca. 140 predefined features. [less ▲]
