Building onFuest et al.(2024), this study examines the financial performance of publicly listed high-and mid-techcompanies from a shareholder'sperspective. Using data from theEU Industrial R\&D Investment Scoreboard and LSEGWorkspace for 2,349 listed companies, market-capitalization-weighted portfolios were constructed and benchmarked against global and local market indices. Performance was evaluated using theSharpe ratio and multi-factor asset pricing models (Carhart four-factor and Fama-French five-factor), distinguishing between crisis and non-crisis periods, as well as regional and sectoral variations. Results showthat, at the aggregate level,high-tech portfolios consistentlyand significantly outperform mid-tech and "other" categories on absolute and risk-adjusted bases. Mid-tech indus-tries exhibitresilience during crisis but lower alphasthan high-techindustries,and sectoral heterogeneity high-lightsdiversification benefits. Furthermore, theanalysis reveals investment opportunities in R\&D-intensive sec-tors, emphasizing crisis resilience and regional competitiveness.}, language = {en} } @article{DienerRoessle2025, author = {Diener, Michael and R{\"o}ßle, Felix}, title = {Cloud certification to foster digital transformation management in public administrations}, series = {Current Issues of Business and Law}, volume = {2025}, journal = {Current Issues of Business and Law}, number = {1(8)}, pages = {30 -- 47}, year = {2025}, abstract = {Public administrations are struggling with the adoption of cloud computing and face more severe challenges in the management than corporations due to special requirements regarding data protection and security. Certification of cloud services is the most promising method in overcoming the current issues. However, this paper examines that existing certificates for cloud service providers don't match the requirements of public administrations. The analyzed cloud certificates focus strongly on the information security management. But they only have a general look on data protection management. The missing focus on the special requirements of public administrations with regards to geo location of servers, the US cloud act, and especially prevention of foreign state access of PII data (personally identifiable information) is most critical for the use in public administrations. This article shows that a FedRAMP equivalent certification process combined with a European cloud certificate especially designed for the public administration could be the trigger to a successful and faster cloud implementation in the public administration sector in Europe that is currently underdeveloped. Furthermore, the large market with millions of buying public administrations in 27 European Union countries would create attractive business opportunities for private cloud providers, foster the development of new applications and serve the strategic goal of data sovereignty.}, language = {en} } @article{RoessleLesser2023, author = {R{\"o}ßle, Felix and Lesser, Kathrin}, title = {Die ESG-Performance des DAX-Index}, series = {Corporate Finance}, volume = {2023}, journal = {Corporate Finance}, number = {01-02}, pages = {23 -- 27}, year = {2023}, abstract = {Dieser Beitrag untersucht anhand des DAX im Zeitraum Januar 2010 bis Juli 2022, ob Unternehmen mit hohen bzw. niedrigen ESG-Scores einen Performanceunterschied aufweisen.

The findings reveal how innovative use of a variety of collaboration and communication technologies helped students and their professors in building emotional connection and compassion to support each other in the midst of the crisis, and to accomplish the project despite connectivity disruptions. The results suggest that the role of an instructor changed to a coach and mentor, and technology was used to create a greater sense of inclusion and co-presence in student-faculty interactions.
