TY - JOUR A1 - Höhne, Stefan A1 - Tiberius, Victor T1 - Powered by blockchain BT - forecasting blockchain use in the electricity market JF - International journal of energy sector management N2 - Purpose: The purpose of this study is to formulate the most probable future scenario for the use of blockchain technology within the next 5–10 years in the electricity sector based on today’s experts’ views. Design/methodology/approach: An international, two-stage Delphi study with 20 projections is used. Findings: According to the experts, blockchain applications will be primarily based on permissioned or consortium blockchains. Blockchain-based applications will integrate Internet of Things devices in the power grid, manage the e-mobility infrastructure, automate billing and direct payment and issue certificates regarding the origin of electricity. Blockchain solutions are expected to play an important big role in fostering peer-to-peer trading in microgrids, further democratizing and decentralizing the energy sector. New regulatory frameworks become necessary. Research limitations/implications: The Delphi study’s scope is rather broad than narrow and detailed. Further studies should focus on partial scenarios. Practical implications: Electricity market participants should build blockchain-based competences and collaborate in current pilot projects. Social implications: Blockchain technology will further decentralize the energy sector and probably reduce transaction costs. Originality/value: Despite the assumed importance of blockchain technology, no coherent foresight study on its use and implications exists yet. This study closes this research gap.

However, although 3D printing technologies seem to be promising, their implementation in practice is complicated. To identify and rank the greatest implementation challenges of 3D printing in dental practices, the present study surveys dentists, dental technicians, and 3D printing companies using a ranking-type Delphi study. Our findings imply that a lack of knowledge is the most crucial obstacle to the implementation of 3D printing technologies. The high training effort of staff and the favoring of conventional methods, such as milling, are ranked as the second and third most relevant factors. Investment costs ranked in seventh place, whereas the lack of manufacturing facilities and the obstacle of print duration ranked below average. An inclusive implementation of additive manufacturing could be achieved primarily through the education of dentists and other staff in dental practices. In this manner, production may be managed internally, and the implementation speed may be increased.

In particular, insured individuals with a healthy lifestyle can receive a reduction of their contributions to be paid. However, this potential is hardly used in practice. Objective This study aims to identify which barrier factors impede the usage of wearables for assessing individual risk scores for health insurances, despite its technological feasibility, and to rank these barriers according to their relevance. Methods To reach these goals, we conduct a ranking-type Delphi study with the following three stages. First, we collected possible barrier factors from a panel of 16 experts and consolidated them to a list of 11 barrier categories. Second, the panel was asked to rank them regarding their relevance. Third, to enhance the panel consensus, the ranking was revealed to the experts, who were then asked to re-rank the barriers. Results The results suggest that regulation is the most important barrier. Other relevant barriers are false or inaccurate measurements and application errors caused by the users. Additionally, insurers could lack the required technological competence to use the wearable data appropriately. Conclusion A wider use of wearables and health apps could be achieved through regulatory modifications, especially regarding privacy issues. Even after assuring stricter regulations, users’ privacy concerns could partly remain, if the data exchange between wearables manufacturers, health app providers, and health insurers does not become more transparent.

T1 - Performance analysis and science mapping of institutional entrepreneurship research T2 - Postprints der Universität Potsdam : Wirtschafts- und Sozialwissenschaftliche Reihe N2 - Institutional entrepreneurship comprises the activities of agents who disrupt existing social institutions or create new ones, often to enable diffusion, especially of radical innovations, in a market. The increased interest in institutional entrepreneurship has produced a large number of scholarly publications, especially in the last five years.

We aim to compile a quantitative overview of the field within business and management research by conducting bibliometric performance analyses and science mappings. We identified the most productive and influential journals, authors, and articles with the highest impact. We found that institutional entrepreneurship has stronger ties to organization studies than to entrepreneurship research. Additionally, a large body of literature at the intersection of institutions and entrepreneurship does not refer to institutional entrepreneurship theory. The science mappings revealed a distinction between theoretical and conceptual research on one hand and applied and empirical research on the other hand. Research clusters reflect the structure–agency problem by focusing on the change agent’s goals and interests, strategies, and specific implementation mechanisms, as well as the relevance of public agents for existing institutions, and a more abstract process rather than agency view.

But when an exogenous shock alters and permanently alters the known normal, entrepreneurs can do no more than cope with the immediate impact. Covid-19 changed the normal for every-one, and the current study aims to analyse how the pandemic changed the context and entrepreneurial perspective of business owners geographically located in different cultural environments. Various experiences impacted them as they tried to navigate and mitigate the effects of the crisis on the wider economy and their business. We seek to identify the probable relevant entrepreneurial configurations in which one or more combinations of antecedent conditions are needed to cause entrepreneurs to adapt their behavior in order to increase their coopetitive interactions further, to mitigate the effects of the crisis.Originality: To the best of our knowledge, this is the first empirical study to address an entrepreneurial phenomenon using an integrative approach using PLS-SEM and fsQCA as separate prediction-oriented methods in order to validate the proposed conceptual model and to create a preliminary scaffolding for building the Theory of Unplanned Behavior in a crisis context.

Objective: We will provide an overview of the annual publication numbers in this field and the most productive and influential countries, journals, and authors, as well as the most used, most co-occurring, and most recent keywords. Methods: Based on a data set of 356 publications and 20,363 citations derived from Web of Science, we conducted a bibliometric analysis using BibExcel, HistCite, and VOSviewer. Results: The strongest growth in publications occurred in 2020, accounting for 29.49% of all publications so far. The most productive countries are the United States, the United Kingdom, and Spain; the most influential countries are the United States, Canada, and the United Kingdom. The most productive journals are the Journal of Medical Internet Research (JMIR), JMIR Serious Games, and the Games for Health Journal; the most influential journals are Patient Education and Counselling, Medical Education, and Quality of Life Research. The most productive authors are Riva, del Piccolo, and Schwebel; the most influential authors are Finset, del Piccolo, and Eide. The most frequently occurring keywords other than “virtual” and “reality” are “training,” “trial,” and “patients.” The most relevant research themes are communication, education, and novel treatments; the most recent research trends are fitness and exergames. Conclusions: The analysis shows that the field has left its infant state and its specialization is advancing, with a clear focus on patient usability.

In KMU und Startups wird die Notwendigkeit von Leitbildern infrage gestellt, da entsprechende Inhalte in der persönlichen Führung vermittelt werden. Doch gerade die gemeinsame Erstellung eines Leitbilds kann dessen Akzeptanz sowie die Mitarbeitermotivation erhöhen. Entsprechend verfolgen wir einen explorativen Aktionsforschungsansatz und entwickelten in einem Workshop mit Mitarbeitern eines in Berlin ansässigen E-Commerce-Startups ein Leitbild. Eine Woche vor und nach dem Workshop wurde die Motivation der Mitarbeiter quantitativ mit Hinblick auf Engagement, Mitarbeiterzufriedenheit, Commitment und Kündigungsabsicht gemessen. Unsere Ergebnisse legen nahe, dass die gemeinsame Formulierung eines Leitbilds einen signifikanten positiven Effekt auf die Mitarbeitermotivation hat, insbesondere für Mitarbeiter mit einem niedrigen initialen Motivationsniveau. N2 - Mission statements have become a popular strategic tool, which increases employee motivation. In SMEs and start-ups, the necessity of mission statements is being questioned as their content can also be communicated by personal leadership. However, especially the participatory development of a mission statement can increase its acceptance and work motivation. Therefore, we pursue an explorative action research approach and developed a mission statement in a workshop with employees of a Berlin-based e-commerce startup. One week before and after the workshop, the employees’ motivation was assessed concerning engagement, satisfaction, commitment and intention to quit. Our results suggest that the participatory development of a mission statement leads to a signifi­cant positive effect on work motivation, especially for employees with a low level of motivation.

Initial theoretical and practical observations in the hospitality industry indicate that business model innovation (BMI) might be a solution to recover from and successfully cope with the COVID-19 crisis. Interestingly, some firms in the hospitality industry already started to successfully adapt their business models. This study explores the why and how of these successful recovery attempts through BMI by conducting a multiple case study of six hospitality firms in Austria. We rely on interview data from managers together with one of their main stammgasts for each case, which we triangulate with secondary data for the analysis. Findings show that BMI is applied during and after the crisis to create new revenue streams and secure a higher level of liquidity, with an important role of stammgasts.
