Out with jobs and in with skills : measuring current circular jobs and analyzing future necessary skills
No full textAbstract: This dissertation explores the labor market transition in Belgium and Flanders from a linear economic model to a circular economy, focusing on sustainable materials management and its contribution to broader sustainable development goals. It explores new ways to monitor circular jobs and skills, the effects of circular economy strategies on skills, and an impact assessment of the COVID-19 crisis on the circular companies and their employees. Using Natural Language Processing, a General Equilibrium model and a Skills Extension Tool, an attempt is made to quantify circular activities and jobs in Belgium and analyze the impact of circular economy policy measures on jobs and skills. Regression analyses investigate the relationship between circular strategies and skills requirements among startups in Flanders, focusing on transport and logistics, research and development, IT, and technical skills. Lastly, the regression analyses also examine the resilience of companies in Flanders during the COVID-19 crisis in relation to their circularity level. The dissertation underscores the importance of proactive policy measures to support companies in building resilience, and to support employees and educational institutions to acquire the necessary skills, especially during times of crisis

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
Work integration ambitions of startups in the circular economy
No full textAbstract: An increasing number of studies illustrate and estimate the potential of the circular economy to create new jobs, most particularly for vulnerable groups at the labor market. This creates collaborating opportunities for Work Integration Social Enterprises (WISEs) and circular economy ventures. Since a shift to a circular economy requires new visions and strategies, startups are considered as powerful engines for the innovation processes needed to support a circular transition. Nevertheless, academic literature at the crossroads of the circular economy, work integration of target groups, and startups remains quasi non-existent. In this paper we present results from survey-data of startups with varying implementation levels of circular strategies, and assess their willingness to cooperate with WISEs, or to engage in other forms of target group employment. We find a strong positive relationship between the implementation of circular strategies and work integration ambitions among startups. Circular startups who need skills on production, transportation, and logistics seek collaboration with WISEs for both inner (repair and redesign) and outer circle (recycling) strategies. Our findings suggest that the circular social economy faces specific barriers that need tailor-made enabling policies. We recommend WISEs to explicitly assess reskilling and upskilling opportunities while embracing the circular economy as a future-proof economic activity
Startups and circular economy strategies : profile differences, barriers and enablers
No full textAbstract: Circular economy practices contribute to achieving sustainability and alleviating the consequences of value chain disruptions and surging prices of energy and raw materials. While startups are increasingly recognized as a powerful engine for innovation processes needed to support this transition, empirical studies on the selection and implementation of circular strategies among startups remains scarce. In this paper, we report findings from the first academic survey on circular startups (N = 165) that allows for multivariate statistical analyses, considering both personal and company characteristics, and perspectives of the entrepreneurs involved. This survey includes startups with varying degrees of implementation levels of a set of 10 circular strategies at different startup lifecycle stages. Our results suggest that younger startup entrepreneurs tend to focus on inner circle strategies, while older startup entrepreneurs rather engage in outer circle strategies or no circular strategies at all. Female startup entrepreneurs are found to be less inclined to combine multiple circular strategies, and business-to-business and business-to-government market segments tend to be frontrunners for circular business models. Circular startups mostly acknowledge sustainability and circularity as a comparative advantage, and startup entrepreneurs with a migrant background seem to be more optimistic to start a profitable circular business. Our results suggest that there is no such thing as \u2018the\u2019 circular economy startup, so we recommend policy makers to develop tailor-made solutions to support startups implementing different circular strategies
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
