The studies researched the learning effects of these games on German university students. Aim: The studies we present investigated if the simulation game-based educational entrepreneurship programs in Germany reached their goals. These goals included the fostering of participants' entrepreneurial competencies and desire to create a startup. Method: We show traditional summative output-oriented results and more profound results based on our theory-based evaluation approach. A so-called logic model provides a framework for the interpretation of what takes place during the entrepreneurship business simulations. Currently, we have conducted research on more than 50 regular university courses with more than 1000 students. Another part of our studies is the evaluation of entrepreneurship education in the German national business game-based competition, EXIST priME Cup (further called EPC). More than 12,000 students attended more than 500 of these cup seminars. We also show new results from an online survey that was carried out to measure the long-term effects of the startup simulation-based seminars. Results: The results of five studies are summarized, and show an overall increase in the participants' knowledge of business administration and business plan preparation skills (required in start-up context). Apart from other results, significant gender-based differences are identified. The differences relate to entrepreneurial attitudes and motivation. Some test scenarios with cup seminars for women only with extended debriefing seem to reduce this decrease in the motivation of women; further research with larger samples is necessary. A new study on the long-term effects shows a very high acceptance rate and demonstrates the satisfaction of former students. The simulation game-based program resulted in participants starting startups at a rate that is approximately twice as high (around 16\%) as the normal rate in Germany.}, language = {en} } @article{deCamposSilvaBaimaRibeirodeBarrosetal., author = {de Campos Silva, Elen Farinelli and Baima, Julio Pinheiro and Ribeiro de Barros, Jaqueline and Tanni, Suzana and Schreck, Thomas and Saad-Hossne, Rogerio and Sassaki, Ligia Yukie}, title = {Risk factors for ulcerative colitis-associated colorectal cancer A retrospective cohort study}, series = {Medicine}, volume = {99}, journal = {Medicine}, number = {32}, publisher = {Lippincott}, doi = {10.1097/MD.0000000000021686}, pages = {1 -- 6}, abstract = {Inflammatory bowel disease is associated with an increased risk of colorectal cancer.

Graves. The purpose of the instrument is to help people identify their personal hierarchies of value systems and thus become more aware of what motivates and demotivates them in work-related contexts. The MVSQ is a forced-choice (FC) measure, making it quicker to complete and more difficult to intentionally distort, but also more difficult to assess its psychometric properties due to ipsativity of FC data compared to rating scales. To overcome limitations of ipsative data, a Thurstonian IRT (TIRT) model was fitted to the questionnaire data, based on a broad sample of N = 1,217 professionals and students. Comparison of normative (IRT) scale scores and ipsative scores suggested that MVSQ IRT scores are largely freed from restrictions due to ipsativity and thus allow interindividual comparison of scale scores. Empirical reliability was estimated using a sample-based simulation approach which showed acceptable and good estimates and, on average, slightly higher test-retest reliabilities. Further, validation studies provided evidence on both construct validity and criterion-related validity. Scale score correlations and associations of scores with both age and gender were largely in line with theoretically - and empirically-based expectations, and results of a multitrait-multimethod analysis supports convergent and discriminant construct validity. Criterion validity was assessed by examining the relation of value system preferences to departmental affiliation which revealed significant relations in line with prior hypothesizing.

Relevant publications and studies contain a large number of proposals for key figures and indicators. These are intended to provide as comprehensive a picture of the transfer process as possible. The point of view of the transfer provider, i.e. the university, is often in the foreground. Until the present moment, transfer recipients such as economy and society have received less attention.

Starting with conceptual remarks on the importance of money for the economy in general, special attention is paid to the unique characteristics of cash. As these become apparent especially during crisis periods, a comparison of the Great Depression (1929 - 1933) and the Great Recession 2008/09 shows the devastating effects of a severe monetary contraction and how a fully elastic provision of cash can help to avoid such a situation. We find interesting similarities to both crises in two separate case studies, one on the demonetization in India 2016 and the other on cash supply during various crises in Greece since 2008. The paper concludes that supply-driven cash withdrawals from circulation (either by demonetization or by capital controls) destabilize the economy if electronic payment substitutes are not instantly available. However, as there is no perfect substitute for cash due to its unique properties, from the viewpoint of the society as a whole an efficient payment mix necessarily includes cash: It helps to stabilize the economy not only in times of crises in general, no matter which government is in place.

The nature of the crisis does, however, determine whether small or large banknote denominations are affected more. This study finds that times of payment uncertainties are associated with increased demand for small denominations, probably reflecting an elevated demand for transaction balances. By contrast, in times of financial crisis or general economic uncertainty, the increased demand for cash is largely the result of consumers taking precautionary actions and building up non-transaction balances; for this reason, there is greater demand for large banknote denominations.

During the COVID-19 pandemic, pediatricians faced a variety of challenges regarding information uptake and transfer to patients, practice organization and consultations for families. This qualitative study aimed at shedding light on German pediatricians' experiences of providing outpatient care during the first year of the pandemic. Methods: We conducted 19 semi-structured, in-depth interviews with pediatricians in Germany from July 2020 to February 2021. All interviews were audio recorded, transcribed, pseudonymized, coded, and subjected to content analysis. Results: Pediatricians felt able to keep up to date regarding COVID-19 regulations. However, staying informed was time consuming and onerous. Informing the patients was perceived as strenuous, especially when political decisions had not been officially communicated to pediatricians or if the recommendations were not supported by the professional judgment of the interviewees. Some felt that they were not taken seriously or adequately involved in political decisions. Parents were reported to consider pediatric practices as sources of information also for non-medical inquiries. Answering these questions was time consuming for the practice personnel and involved non-billable hours. Practices had to adapt their set-up and organization immediately to the new circumstances of the pandemic, which proved costly and laborious as well. Some changes in the organization of routine care, such as the separation of appointments for patients with acute infection from preventive appointments, were perceived as positive and effective by some study participants. Telephone and online consultations were established at the beginning of the pandemic and considered helpful for some situations, whereas for others these methods were deemed insufficient (e.g. for examinations of sick children). All pediatricians reported reduced utilization mainly due to a decline in acute infections. However, preventive medical check-ups and immunization appointments were reported to be mostly attended. Conclusion: Positive experiences of reorganizing pediatric practice should be disseminated as "best practices" in order to improve future pediatric health services. Further research could show how some of these positive experiences in reorganizing care during the pandemic are to be maintained by pediatricians in the future.}, language = {en} } @incollection{SuezeroğluMelchiorsBader, author = {S{\"u}zeroğlu-Melchiors, Sevim and Bader, Martin A.}, title = {How to Increase the Success of Innovative Start-Ups with Intellectual Property: An Introductory Overview}, series = {Intellectual Property Management for Start-ups}, booktitle = {Intellectual Property Management for Start-ups}, publisher = {Springer}, doi = {10.1007/978-3-031-16993-9_1}, pages = {1 -- 25}, abstract = {This introductory chapter builds on the topic of intellectual property management and its relevance to the success of innovative start-ups.

However, we show that there are also indications that consumers were somewhat pushed into cashless payments by government regulations and supply-side restrictions by commercial banks. Nonetheless, overall demand for euro cash remained strong and even increased relative to GDP since the financial crisis in 2008.

This chapter discusses many methodological challenges that have plagued the measurement of the link between age and productivity. It reviews micro- and macroeconomic studies and juxtaposes them with the literature on the relationship between population ageing and aggregate productivity. The methodologically most convincing studies on individual productivity in standard jobs find an initial increase in productivity, probably a learning effect, but then productivity remains flat until retirement. These micro-level studies measure productivity in a given technological environment and therefore ignore the contribution to productivity from improving this environment. This is where macro studies come into play, which suggest a negative influence of population ageing on total factor productivity. While the microeconomic and the macroeconomic evidence appear to contradict each other, they do not because they measure different relationships that are not linked through simple aggregation.

The purpose of this paper is to advance this area of research by examining how the use of external patent attorneys influences the patent filing strategies of firms and what impact firms? level of experience with the exclusive use of in-house resources has on filing strategies. This study, thus, provides insights into the strategic dimension behind patent filing, a process which is affected by patent attorneys? work and decision-making processes.Design/methodology/approachThe econometric analysis is based on a patent database of 922,553 patents which is combined with an EPO patent database covering applications from 1990 to 2010. The authors test the hypotheses for this study using patent indicators addressing the impact of in-house firm experience vs the use of external patent attorneys on firm?s filing strategy.FindingsThis research finds empirical evidence that external patent attorneys? work has an effect on patent scope, international scope, and patenting speed. Moreover, it can be shown that external patent attorneys have a positive impact on most filing dimensions, such as patent scope, international scope and the Patent Cooperation Treaty option, whereas the level of in-house firm experience has a negative impact on most filing dimensions. This implies that external patent attorneys seem to pursue a ?maximization approach? while experienced firms seem to pursue a more differentiated approach to filing patents, for instance, drafting narrower and more focused patents.Practical implicationsThe study suggests that effective filing strategies require an integrated approach between diverse IP stakeholders. More particularly, filing strategies should be communicated and aligned between all actors, including external patent attorneys in order to achieve the targeted patenting output.Originality/valueThe current study develops a patent filing typology, which accounts for patent attorneys? decision options.
