Driving Toward Circular Business Models: Conditions and Strategies in the Built Environment
No full textThe world is increasingly facing crises and shocks, with the climate crisis being the defining crisis of our time, affecting all facets of life on our planet: from coral reefs and species dying, weather extremes, food and water insecurity, economic disorder, international conflicts, and terrorism (United Nations, 2023b). The immeasurable costs of climate change are reaching irreparable highs. The United Nations (UN) (2023a) testify that progress toward sustainable development is underway, for instance through green energy advances and more secure food supplies. However, although progress has started, there is still a pressing need for major transformations across all aspects of society.To assist in steering the transition, the circular economy—and particularly circular business models (CBMs) and circular business model innovation (CBMI)—has been proposed as a promising avenue to reach sustainable development through a change to business operations that profit from a circular (reduce, reuse, recycle) model instead of the outmoded linear (take, make, waste) model.The built environment is a principal contributor to climate change, and with a rapidly growing global population, the need for housing continues to soar, catapulting the environmental, social, and economic impacts of the built environment to its peak (World Green Building Council, 2023). Considering its significant impact, it is essential that the built environment delivers transformational change to ensure sustainable built environments for the future, as it poses a crucial facet to fighting climate change, and driving economic security whilst also creating resilient societies (World Green Building Council, 2023). Resilience in the built environment has been studied at firm, industry, and society level, but the literature has not sufficiently examined resilience in the built environment across the different levels to investigate how resilience at one level can impact resilience at other levels (Kennedy & Linnenluecke, 2022), Aiming to respond to the needs of today, this thesis seeks to answer the following research questions:RQ 1: What conditions and strategies lead to CBM adoption and CBMI?RQ 2: What are the resulting effects of CBMs on resilience across levels in the built environment?This thesis comprises three core articles. Article A presents a systematic literature review and identifies 54 different determinants that drive or hinder CBM adoption, classifying them into eight macro categories: culture, regulation, market, strategy, business case, collaboration, operations, and knowledge. Article B employs a three-round Delphi method with 25 experts to categorize the drivers and barriers to CBMI in the built environment, and develops 34 strategies for practitioners in the built environment to capitalize on the drivers and overcome the barriers. These strategies are classified into four proposed categories regarding how they can assist in changing resource loops: ‘Understanding the loop,’ ‘Facilitating the loop,’ ‘Promoting the loop,’ and ‘Regulating the loop’. Article C then cross-compares four circular and four linear startups from one entrepreneurial ecosystem, and presents how the circular startups’ innate nurturing of their ecosystem has trickle-up effects to multiple levels’ resilience in response to crises, using the material crisis as its crisis context.Woven together, this thesis contributes to the literature on circular business model innovation and adoption, the built environment, and resilience. This thesis contributes to the literature by developing an in-depth review of the current literature on driving and hindering conditions to CBM adoption and CBMI, the strategies that can be used to tackle these conditions for CBMI in the built environment, and the impact of CBMs on resilience across levels

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
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
Determinants of circular business model adoption—A systematic literature review
No full textAlthough the circular economy is considered an avenue to sustainable development, the transition toward circularity is moving slowly. Academic literature has examined how various factors can affect the adoption of circular business models in specific industries and organizational types. However, no research has systematically reviewed the determinants of circular business model adoption. Through a systematic literature review, this study provides a holistic overview of the determining drivers of and barriers to the adoption of circular business models. Building on a sample of 67 journal articles, this study identifies 54 different determinants and classifies them into eight macro categories: culture, regulation, market, strategy, business case, collaboration, operations, and knowledge. The findings can guide policy-makers, researchers, and decision makers across industries in understanding what obstacles to avoid and drivers to employ when they wish to increase circular business model adoption.</p
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
