From Startup Support to System Transformation: Intermediaries in Circular Entrepreneurial Ecosystems
No full textDiese Dissertation untersucht, wie Intermediäre zirkuläre Startups innerhalb von Entrepreneurial Ecosystems (EEs) unterstützen und wie ihre Aktivitäten zur Transformation hin zu einer Circular Economy (CE) auf Ökosystem- und institutioneller Ebene beitragen. Obwohl das Interesse an zirkulärem Unternehmertum und EEs wächst, fehlt bislang ein integriertes Verständnis darüber, wie Intermediäre die Struktur von Ökosystemen, deren relationale Dynamiken sowie institutionelle Logiken prägen und dadurch die Entwicklung zirkulärer Startups beeinflussen.
Zur Schließung dieser Forschungslücke verfolgt die Arbeit ein multimethodisches Forschungsdesign. Eine systematische Literaturrecherche (SLR) konzeptualisiert Circular Entrepreneurial Ecosystems (CEEs), indem sie aufzeigt, wie etablierte Ökosystemelemente qualitativ neu ausgerichtet werden müssen, um den Bedürfnissen zirkulärer Startups gerecht zu werden. Empirische Analysen auf der Grundlage von einer Sozialen Netzwerkanalyse und Experteninterviews erweitern diese Konzeptualisierung, indem sie die strukturelle Entstehung von CEEs untersuchen und intermediärzentrierte, wenig verdich-tete und vertrauensbasierte Subökosysteme identifizieren. Da beide Studien die zentrale Bedeutung von Intermediären für die Gestaltung von CEEs hervorheben, untersucht die dritte Studie ihre Funktionen systematisch. Eine zweite SLR entwickelt hierfür ein Mehrebenenframework intermediärer Einflussmechanismen, das Konfigurationen, Wirkungsmechanismen und Ergebnisse auf der Mikro-, Meso- und Makroebene abbildet. Die vierte Studie analysiert, wie sich diese Funktionen in institutionellen Logiken manifestieren. Die Studie zeigt, dass Intermediäre die Community und Entrepreneurial-Market Logik weitergeben und eine bisher nicht erkannte transversale zirkuläre Logik kultivieren. Diese Logik fungiert als zusätzliche Ebene und definiert unternehmerische Zielsetzung, Legitimität und Wertschöpfung neu. Da die vorangegangenen Studien belegen, dass Intermediäre das strukturelle und institutionelle Rückgrat von CEEs bilden, muss zur Stärkung der Kreislaufwirtschaft auf diesen bestehenden Mechanismen aufgebaut werden. Vor diesem Hintergrund entwickelt und validiert ein Design-Science-Research-Ansatz ein Circular Support Aligment Artefakt, das Intermediären ermöglicht CE in ihre Unterstützungsstrukturen zu integrieren und die systemische Ausrichtung innerhalb von CEEs zu verbessern.
Diese Dissertation leistet mehrere Beiträge. Konzeptionell führt sie CEEs als analytisches Rahmenwerk zur Untersuchung zirkulären Unternehmertums ein. Theoretisch identifiziert sie Zirkularität als transversale institutionelle Logik und positioniert Intermediäre als institutionelle Unternehmer, die zu einer Transformation hin zu einer CE beitragen. Empirisch liefert sie Evidenz für die Herausbildung von CEEs sowie für intermediärgetriebene relationale Dynamiken. Methodisch und praktisch stellt sie validiertes Designwissen bereit, das Intermediäre dabei unterstützt, ihre Aktivitäten an Zirkularität auszurichten und ihre systemische Rolle innerhalb von CEEs zu stärken
Systems and Ecosystems in the Circular Economy: What’s the Difference?
No full text‘Systems’ and ‘ecosystems’ are buzz concepts in the circular economy literature. However, the differences between these concepts remain ambiguous. Systems and ecosystems are often used interchangeably and at times confusingly. While conceptual ambiguity offers possibilities for broad interpretations and engagement, it can undermine the relevance of these concepts as analytical lenses to disrupt the linear economy. In this perspective article, I examine whether systems and ecosystems are distinct concepts and how they complement each other. To do so, I analysed these concepts and applied them to a case of biomethane for transportation using scientific literature. Systems and ecosystems are not mutually exclusive; rather, they offer nuanced perspectives to describe, analyse, and facilitate complex interactions among entities and their external environment. They signify the complexity, interdependency, and co-evolutionary nature of the circular economy. Ecosystems are a subcategory of systems. Differences between the concepts of systems and ecosystems partially arise from their origins, evolution, and the research communities using them. The article shows how systems and ecosystems perspectives can enrich each other and calls for better integration between the two concepts in the circular economy discourse.
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Stimulating the diffusion of environmental technologies through export
No full textContemporary environmental problems represent complex societal challenges, and as these problems become increasingly global, the international diffusion of environmental technologies is essential. One way to diffuse technologies internationally is through export. Despite the potential benefits from the adoption of environmental technologies, their export is stifled by externalities and free-rider problems. From this background, the aim of this thesis is to analyse how to stimulate the diffusion of environmental technologies through export. This aim is operationalised using four research questions, which focus on governmental initiatives to promote environmental technology export and their perceived effectiveness among targeted firms, obstacles to and drivers for export among municipally owned companies, the use of international city networks to facilitate environmental technology export and components of business concepts for environmental technology export. These questions are explored in the Swedish context using document analyses, interviews and internet surveys in a compilation thesis which consists of a cover essay and an appendix of five scientifically peer-reviewed and published journal articles. The conclusions are that governmental export promotion initiatives are often generic for all kinds of exporters, including environmental technologies, and comprise financial support, information provision, education and training, and trade and mobility-related programs, often with little incorporation of the specific characteristics of environmental technologies which many exporters perceive as ineffective. Municipally owned companies experience different barriers to and drivers for engaging in international activities compared to privately owned companies, and are often involved in international projects which are not always commercial export. International city networks serve as important arenas for bi-directional information sharing and learning regarding market characteristics, environmental challenges and potential solutions, building legitimacy for technologies and their suppliers. Regarding components of business concepts for the export of environmental technologies, regulation, legitimacy and private-public partnership are identified as particularly important based on the complexity and systemic nature of environmental technologies. Altogether, this thesis makes a contribution by conceptualising the export of environmental technologies with emphasis on technology characteristics, the technology supplier including their business concepts, obstacles to and drivers for export, technology adopters and their characterisation, communication channels and the diffusion context. For policy makers, a dynamic approach to environmental technology export promotion, in which specific attributes of environmental technologies and their suppliers are considered along their international business development, is suggested as a complement to existing generic initiatives. The possibility to provide such support should be reconciled with resource effectiveness, heterogeneity among companies and the complementary role of governmental interventions to market initiatives. Finally, partnerships between publicly and privately owned companies are suggested as particularly relevant since they build on the long-term experience, functioning proof-of-concept and legitimacy of publicly owned companies together with the competitiveness and flexibility of privately owned companies. These attributes could help overcome the liabilities of foreignness and newness, as well as resource constraints which challenge environmental technology export.De stora miljöproblemen innebär komplexa samhällsutmaningar och allt eftersom miljöproblemglobaliseras ökar behovet av en internationell spridning av miljöteknik. Export är ett sätt attsprida teknologier internationellt, men trots de potentiella fördelarna med miljöteknikexportstöter det ofta på hinder. Exempel på sådana hinder är externa effekter som att miljönytta intetillfaller det exporterande företaget, och att konkurrenter åker snålskjuts på de företag som tar deinitiala stegen. Utifrån denna bakgrund syftar den här avhandlingen till att analysera hur miljöteknikexport kanstimuleras ytterligare. För att besvara syftet har fyra frågeställningar utformats som fokuserar påstatliga initiativ för att främja export av miljöteknik och hur deras effekter uppfattas bland företagi målgruppen; hinder och drivkrafter för export hos kommunala bolag; internationella nätverkmellan storstäder som arenor för att underlätta export av miljöteknik; samt affärsmodeller för attexportera miljöteknik. Frågeställningarna utforskas i ett svenskt sammanhang genomdokumentanalys, intervjuer och enkäter. Avhandling bestående av en sammanfattande ”kappa”och fem publicerade vetenskapliga artiklar. Resultaten från avhandlingen visar att statliga initiativ för att främja export oftast är generiska förolika typer av exportörer inklusive miljöteknikföretag. Initiativen inkluderar vanligtvis finansielltstöd, information, utbildning samt stöd för marknadsbesök och mobilitet. Dock tas ingen störrehänsyn till de särskilda egenskaperna hos miljöteknik vid utformandet av stödet. Stödet uppfattasdessutom av många miljöteknikexportörer som ineffektivt. Kommunala bolag har andra hinderoch drivkrafter än privata företag för att engagera sig internationellt och är oftast involverade iprojekt som inte är direkta exportaktiviteter. Internationella nätverk mellan städer kan fungerasom arenor för informationsutbyte och lärande mellan olika aktörers marknadsegenskaper,miljöproblem och potentiella lösningar samt bidra till legitimitet för tekniken och dessleverantörer. När det gäller utveckling av affärsmodeller för att exportera miljöteknik framstårlagstiftning, legitimitet, och samarbete mellan privata och offentliga aktörer som särskilt viktigt attbeakta på grund av miljöteknikens komplexitet och systemiska natur. Sammanfattningsvis bidrar avhandlingen till en konceptualisering av miljöteknikexport genom attfokusera på teknikens egenskaper, dess leverantörers affärsmodeller, hinder och drivkrafter förexport, de som köper tekniken och deras egenskaper, kommunikationskanaler samt sammanhangdär spridningen sker. En rekommendation är att politiska beslutsfattare borde stödja export avmiljöteknik på ett dynamiskt sätt där specifika egenskaper hos miljöteknik och dess leverantörerbeaktas i takt med deras internationella affärsutveckling. En dynamisk ansats kan vara ett brakomplement till många befintliga generiska statliga initiativ för att främja export av miljöteknik.En sådan ansats bör ta hänsyn till resurseffektivitet, olikheter mellan företag, samt varakomplementär till de icke-statliga initiativ som redan finns på marknaden. Slutligen föreslåssamarbeten mellan offentliga och privatägda företag, vilket anses högst relevant eftersomoffentliga företag kan bidra till att kombinera den mångåriga erfarenheten av miljötekniskalösningar samt den legitimitet som sådana företag kan ha med privata företags styrkor så somkonkurrenskraft och flexibilitet. Dessa förslag kan bidra till att minska de exporthinder som haratt göra med att miljöteknik ofta är ny och främmande, samt miljöteknikföretagens oftabegränsade resurser
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
