The implications of entrepreneurs’ previous experiences on using a scientific approach to decision making: evidence from a randomized control trial
Full text linkThis study aims to investigate if previous managerial or entrepreneurial experiences of entrepreneurs could moderate the use of a scientific approach to decision-making. To test this, we embedded a field experiment involving 132 real start-ups from Italy. We collected data on performances using phone calls for 64 weeks. Using econometrics analysis, we find that previous managerial or entrepreneurial experiences moderate the effect of this entrepreneurial decision-making approach on start-up performances, such as whether they decided to terminate their entrepreneurial idea, the number of pivots and the amount of revenue gained. The moderating effects differ according to the experiences possessed by entrepreneurs
DOES ENTREPRENEURSHIP EDUCATION AFFECT PHD’S ACADEMIC AND BUSINESS PERFORMANCE?
No full textThis study aims to investigate the impact entrepreneurial education programs can have on academic and business performance of researchers. We analysed the academic and business results of 73 PhDs who attended an entrepreneurial education program codesign by universities and an international research centre in the last five years compared to 73 PhDs who did not. We based our analysis on a mix of quantitative and qualitative data regarding scientific and entrepreneurial achievements and interviews with former participants to the entrepreneurial education program. Evidence from our analysis shows a positive effect of the entrepreneurial education program on academic and business results
Assessing the importance of managerial and entrepreneurial experience in entrepreneurial training programs
No full textDo entrepreneurs’ managerial and entrepreneurial experiences influence the effectiveness of the entrepreneurial training (ET) programs they receive? We address this question through a field experiment conducted within a pre-incubation program that involves 132 early-stage start-ups in Italy. Half of the participants received ET based on the scientific approach to decision-making, and the remaining received heuristic training. We exploit exogenous variation from the experiment to show that only entrepreneurs without any managerial or entrepreneurial experience see the effects of ET in terms of the termination of nonpromising projects and pivot decisions. Conversely, only entrepreneurs with previous managerial or entrepreneurial experience see the effects of ET in terms of superior early revenue generated. These findings highlight the importance of designing tailored ET programs according to the prior experience of entrepreneurs
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
A learning-by-doing approach to entrepreneurship education: evidence from a short intensive online international program
Full text linkEntrepreneurship is considered a key driver for economic growth. Therefore, more and more studies are investigating the role and effectiveness of entrepreneurship education. In this context, the present study is aimed at investigating the effectiveness of entrepreneurship programs, with a learning-by-doing approach, on the entrepreneurial intention, entrepreneurial characteristics (entrepreneurial attitude, entrepreneurial self-efficacy, entrepreneurial mindset, core self-evaluation) and entrepreneurial skills (creativity, financial literacy, marshaling of resources, planning, teamwork). The study has analyzed a short intensive online entrepreneurship program, which adopts a learningby-doing approach and targets students from different European technical universities, with different levels of education and different entrepreneurial backgrounds, giving them the opportunity to work on different types of projects. Pre-and post-course surveys were conducted in order to perform qualitative analyses on the effectiveness of the program. The results show that the entrepreneurial intention and perception of the entrepreneurial characteristics and skills of the students increased after participation in the program. In addition, our findings reveal that the program appears to be more effective for MSc students than for PhD ones and for students who had never attended any entrepreneurship program before, while there is no difference in the effectiveness of the program in terms of gender
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
