How much is too much? The effects of information quantity on crowdfunding performance
No full textWe explore the effects of the quantity of information on the tendency to contribute to crowd-funding campaigns. Using the crowdfunding platform Kickstarter, we analyze the campaign descriptions and the performance of over 70,000 projects. We look empirically at the effect of information quantity (word count) on funding success (as measure by amount raised and number of backers). Within this empirical approach, we test whether an excessive amount of information will affect funding success. To do so, we test for the non-linearity (quadratic) effect of our independent variable (word count) using regression analysis. Consistent with the hypothesis that excess information will negatively affect funds raised and number of contributors, we observe a consistent U-shaped relationship between campaign text length and overall success which suggest that an optimal number of words exists within crowdfunding texts and that going over this point will reduce a project's chance of fundraising success
The effects of money saliency and sustainability orientation on reward based crowdfunding success
No full textCommunication is a key determining factor of success in crowdfunding environments. In this paper, we examine the link between language used by founders and the contribution behavior of funders. Particularly, we investigate how verbal cues – money saliency and sustainability intention – in the communication text can affect the size of the contributing crowd and amount raised in the context of Kickstarter. Given the nature of crowdfunding environments (intrinsically motivated stakeholders) and Kickstarter's rewards-based structure, we hypothesize that there is a potential crowding-out effect in which an increased level of money saliency leads to decreased funding contributions and engagement. However, this effect should be weaker among projects that have non-selfish aims or intentions. Our analysis on close to 80,000 Kickstarter campaigns confirms that there is indeed a price to pay for using monetary-related terms in project descriptions but not among projects identified as sustainability oriented

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
Personality and individual characteristics as indicators of lifetime climbing success among Everest mountaineers
No full textTo measure the importance of personality and individual characteristics in such extreme environments as high-altitude mountaineering, this study investigated how physical, physiological, and/or hormonal markers provide insights into individual predilections for competitive and risk-taking behaviours. Because climbing outcomes depend on the ability to overcome adverse environmental conditions, avoid unnecessary risks, and exert sufficient self-regulation to handle extreme physiological and psychological stressors, it focused particularly on the relation between the successful scaling among Mount Everest climbers and risk attitudes, personality factors (from the Big Five Inventory) or traits associated with prenatal androgen exposure (2D:4D ratio). The results indicate not only that the 2D:4D ratio positively predicts lifetime mountaineering success but that the more risk averse open-minded and emotionally stable the climbers, the more active and successful compared to their peers. These findings, in addition to suggesting that human biological and psychological traits substantially influence success and long-term performance in extreme situations, offer valuable insights into how humans with different tendencies are likely to behave under such stressful conditions
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
