    Urban supply networks are facing increasing demands and challenges and thus constitute a relevant field for research and practical development. Supply chain management holds enormous potential and relevance for society and everyday life as the flow of goods and information are important economic functions. Being a heterogeneous field, the literature base of supply chain management research is difficult to manage and navigate. Disruptive digital technologies and the implementation of cross-network information analysis and sharing drive the need for new organisational and technological approaches. Practical issues are manifold and include mega trends such as digital transformation, urbanisation, and environmental awareness. A promising approach to solving these problems is the realisation of smart and collaborative supply networks. The growth of artificial intelligence applications in recent years has led to a wide range of applications in a variety of domains. However, the potential of artificial intelligence utilisation in supply chain management has not yet been fully exploited. Similarly, value creation increasingly takes place in networked value creation cycles that have become continuously more collaborative, complex, and dynamic as interactions in business processes involving information technologies have become more intense. Following a design science research approach this cumulative thesis comprises the development and discussion of four artefacts for the analysis and advancement of smart and collaborative urban supply networks. This thesis aims to highlight the potential of artificial intelligence-based supply networks, to advance data-driven inter-organisational collaboration, and to improve last mile supply network sustainability. Based on thorough machine learning and systematic literature reviews, reference and system dynamics modelling, simulation, and qualitative empirical research, the artefacts provide a valuable contribution to research and practice

    Das vorliegende kumulative Dissertationsprojekt besteht aus fünf Fachbeiträgen und befasst sich mit pferdegestützten Interventionen aus der Perspektive von Kindern. Zunächst wird eine kritische Auseinandersetzung mit dem Forschungsfeld tiergestützter Interventionen vorgenommen, da hier häufig Erklärungsansätze herangezogen werden, die wissenschaftlich nicht abgesichert sind. Diese Ansätze sollen in der eigenen Arbeit nicht reproduziert werden. Für die Erhebung des Forschungsstandes werden Studien herangezogen, welche sich mit der psychischen, sozialen und emotionalen Wirkung pferdegestützter Interventionen bei Kindern befassen. Das bearbeitete Forschungsdesiderat ergab sich aus der Betrachtung bestehender Studien, da die Kinderperspektive in diesem Zusammenhang bisher kaum wissenschaftlich betrachtet wurde. Um zu verstehen, was für Kinder an pferdegestützten Interventionen relevant ist, wird ein Forschungsdesign verwendet, welches die Kinder in den Forschungsprozess einbezieht, sodass sie ihre eigenen Relevanzen explizieren können. Somit wird eine neue Perspektive auf bestehende Forschungsergebnisse eröffnet, welche ein tieferes Verständnis für die Wirkweisen pferdegestützter Interventionen bietet und die Möglichkeit zur Evaluation der praktischen Durchführung beinhaltet. Die Ergebnisse beruhen auf der Befragung von 23 Kindern die wöchentlich an einer pferdegestützten Intervention teilnahmen. Die meisten der Kinder lebten zum Zeitpunkt des Interviews in Einrichtungen der Kinder- und Jugendhilfe und nicht bei ihren Familien und standen somit unter erhöhter psychosozialer Belastung. Wie Kinder pferdegestützte Förderung wahrnehmen, wird mit Hilfe von offenen Leitfadeninterviews und der Grounded Theory herausgearbeitet. Als zusätzliche Ausdrucksmöglichkeit der Kinder wurden Bilder, die sie vom pferdegestützten Setting malten, als ergänzendes Material genutzt und mittels Segmentanalyse ausgewertet. Am Ende der Arbeit ist festzuhalten, dass in pferdegestützten Interventionen, mit dem Ziel der Förderung von mentaler Gesundheit, reitpädagogische Fachkräfte Situationen mit Pferden konstruieren, die das interpersonale Vertrauen und das Selbstvertrauen von Kindern stärken, indem gezielt die Bewältigung von Herausforderungen mit dem Pferd unterstützend angeleitet wird. Insbesondere die zentrale Rolle der reitpädagogischen Fachkraft sowie relevante Wirkfaktoren werden vertieft betrachtet

    Klarnetin staccato tekniğini güçlendirme aşamaları eser çalışmalarıyla uygulanmıştır. Staccato geçişlerini hızlandıracak ritim ve nüans çalışmalarına yer verilmiştir. Çalışmanın en önemli amacı sadece staccato çalışması değil parmak-dilin eş zamanlı uyumunun hassasiyeti üzerinde de durulmasıdır. Staccato çalışmalarını daha verimli hale getirmek için eser çalışmasının içinde etüt çalışmasına da yer verilmiştir. Çalışmaların üzerinde titizlikle durulması staccato çalışmasının ilham verici etkisi ile müzikal kimliğe yeni bir boyut kazandırmıştır. Sekiz özgün eser çalışmasının her aşaması anlatılmıştır. Her aşamanın bir sonraki performans ve tekniği güçlendirmesi esas alınmıştır. Bu çalışmada staccato tekniğinin hangi alanlarda kullanıldığı, nasıl sonuçlar elde edildiği bilgisine yer verilmiştir. Notaların parmak ve dil uyumu ile nasıl şekilleneceği ve nasıl bir çalışma disiplini içinde gerçekleşeceği planlanmıştır. Kamış-nota-diyafram-parmak-dil-nüans ve disiplin kavramlarının staccato tekniğinde ayrılmaz bir bütün olduğu saptanmıştır. Araştırmada literatür taraması yapılarak staccato ile ilgili çalışmalar taranmıştır. Tarama sonucunda klarnet tekniğin de kullanılan staccato eser çalışmasının az olduğu tespit edilmiştir. Metot taramasında da etüt çalışmasının daha çok olduğu saptanmıştır. Böylelikle klarnetin staccato tekniğini hızlandırma ve güçlendirme çalışmaları sunulmuştur. Staccato etüt çalışmaları yapılırken, araya eser çalışmasının girmesi beyni rahatlattığı ve istekliliği daha arttırdığı gözlemlenmiştir. Staccato çalışmasını yaparken doğru bir kamış seçimi üzerinde de durulmuştur. Staccato tekniğini doğru çalışmak için doğru bir kamışın dil hızını arttırdığı saptanmıştır. Doğru bir kamış seçimi kamıştan rahat ses çıkmasına bağlıdır. Kamış, dil atma gücünü vermiyorsa daha doğru bir kamış seçiminin yapılması gerekliliği vurgulanmıştır. Staccato çalışmalarında baştan sona bir eseri yorumlamak zor olabilir. Bu açıdan çalışma, verilen müzikal nüanslara uymanın, dil atış performansını rahatlattığını ortaya koymuştur. Gelecek nesillere edinilen bilgi ve birikimlerin aktarılması ve geliştirici olması teşvik edilmiştir. Çıkacak eserlerin nasıl çözüleceği, staccato tekniğinin nasıl üstesinden gelinebileceği anlatılmıştır. Staccato tekniğinin daha kısa sürede çözüme kavuşturulması amaç edinilmiştir. Parmakların yerlerini öğrettiğimiz kadar belleğimize de çalışmaların kaydedilmesi önemlidir. Gösterilen azmin ve sabrın sonucu olarak ortaya çıkan yapıt başarıyı daha da yukarı seviyelere çıkaracaktır

    Setting contextual conditions to resolve grand challenges through responsible innovation:A comparative patent analysis in the circular economy

    Get PDF
    Copyright © 2023 The Authors. This article draws on responsible innovation (RI) undertaken by hybrid organizations, institutional rigidity, and national innovation systems (NISs) to assess and contextualize the innovation performance of for-profit firms seeking to resolve grand challenges (GCs). The extant research on RI lacks the theoretical underpinnings to profile the unique characteristics of RI firms and the contextual conditions behind the resolution of GCs through RI. This study aims to fill this important gap by focusing on a specific type of RI firm—a firm seeking to reduce climate change through implementation of a circular economy model. By studying a multi-country sample of 1153 manufacturing firms, we implemented propensity score matching (PSM) and the Heckman selection model to compare the patent productivity of RI and non-RI firms. Our evidence demonstrates that RI firms display lower likelihood of patenting and lower patent productivity than non-RI firms when they do engage in patenting. Furthermore, we found that a stronger national R&D environment can be conducive to aligning public interests and private incentives by enabling RI firms to enhance their patent productivity. Additionally, RI firms in industries with lower levels of technological complexity capture more value from improvements in R&D environments than RI firms in industries with higher levels of technological complexity. Our argument as a whole contributes to the GC and RI literature streams by considering both the innovation barriers faced by RI-oriented firms and the macro/industry boundary conditions that enable such organizations to overcome them.Governments of Spain and Andalusia (Research Project A-SEJ-196-UGR20); Schoeller Foundation; Taishan Scholar Program of Shandong Province

    Imagination as Thought in Aristotle\u27s De Anima

    Get PDF
    Aristotle appears to indicate in various passages in the De Anima that imagination is a kind of thought, and my thesis attempts to make some sense out of this claim. I examine three possible interpretations of the claim that imagination is a kind of thought and eliminate two of them. The first states that Aristotle only calls imagination a kind of thought in a superficial “in name only” sense. The second, more radical interpretation, identifies images as the most basic kind of thoughts. My final chapter defends a more moderate position—inspired by Avempace and the early Averroes—which steers between the superficial and radical interpretations, by construing the formal content of images as a sort of quasi-corporeal substrate for the generation of learned thoughts

    Towards a sociology of conspiracy theories: An investigation into conspiratorial thinking on Dönmes

    Get PDF
    This thesis investigates the social and political significance of conspiracy theories, which has been an academically neglected topic despite its historical relevance. The academic literature focuses on the methodology, social significance and political impacts of these theories in a secluded manner and lacks empirical analyses. In response, this research provides a comprehensive theoretical framework for conspiracy theories by considering their methodology, political impacts and social significance in the light of empirical data. Theoretically, the thesis uses Adorno's semi-erudition theory along with Girardian approach. It proposes that conspiracy theories are methodologically semi-erudite narratives, i.e. they are biased in favour of a belief and use reason only to prove it. It suggests that conspiracy theories appear in times of power vacuum and provide semi-erudite cognitive maps that relieve alienation and ontological insecurities of people and groups. In so doing, they enforce social control over their audience due to their essentialist, closed-to-interpretation narratives. In order to verify the theory, the study analyses empirically the social and political significance of conspiracy theories about the Dönme community in Turkey. The analysis comprises interviews with conspiracy theorists, conspiracy theory readers and political parties, alongside a frame analysis of the popular conspiracy theory books on Dönmes. These confirm the theoretical framework by showing that the conspiracy theories are fed by the ontological insecurities of Turkish society. Hence, conspiracy theorists, most readers and some political parties respond to their own ontological insecurities and political frustrations through scapegoating Dönmes. Consequently, this work shows that conspiracy theories are important symptoms of society, which, while relieving ontological insecurities, do not provide politically prolific narratives

    Devido à intensificação da cooperação entre a China e os países lusófonos, a aprendizagem de Português torna-se cada vez mais fundamental na China hoje em dia. Sendo uma língua radicalmente diferente da sua primeira língua, os aprendentes chineses normalmente manifestam um conjunto de dificuldades em certos aspetos, enquanto a diferença cultural e oportunidades limitadas de treinar a língua-alvo fora da sala de aula também dificultam a sua aquisição de Português. Se bem que alguns autores tenham evidenciado a existência de problemas na aprendizagem dos aprendentes chineses, não esclareceram as soluções praticáveis. Em conformidade com as caraterísticas dos estudantes nos dias de hoje, os quais dedicam bastante tempo às redes sociais na sua vida quotidiana, consideramos que a introdução das ferramentas sociais pode ser potencialmente uma abordagem razoável para promover a aprendizagem de Português, o que nos levou a focalizar-nos em estudar o impacte do uso do Weibo, uma plataforma de microblogue de origem chinesa, relativamente às capacidades escritas dos aprendentes chineses. Optámos por aplicar uma triangulação de metodologias para analisar a participação, motivação, publicações, resultados dos dois testes realizados antes e depois das atividades e das entrevistas com os participantes, a fim de obter um entendimento o mais completo possível das potencialidades do Weibo. Três intervenções foram conduzidas com os objetivos, respetivamente, de verificar a possibilidade da criação de uma comunidade de aprendizagem colaborativa mediante a ferramenta selecionada, e identificar a influência da interação entre os aprendentes chineses e portugueses e entre os chineses e a docente nativa em relação às capacidades escritas em Português. De acordo com os resultados atingidos, além de revelarem uma motivação e satisfação relativamente positivas, os aprendentes participantes geralmente demonstram um melhor comportamento a respeito da concordância verbal e da morfologia das palavras, e alguns deles também manifestam um progresso evidente nos aspetos do uso dos tempos e modos verbais e da concordância nominal de número. Já os participantes da última intervenção obtêm uma pontuação mais elevada na compreensão escrita do que os não participantes de modo geral, revelando as potencialidades e eficiência da aplicação do Weibo na aprendizagem de Português por falantes chineses. Consideramos que a introdução desta rede social com estratégia de aprendizagem pode proporcionar influências positivas, conduzindo à proposta de realização de estudos mais aprofundados e de uma aplicação mais aturada na prática didática do Português Língua nãoMaterna numa futura etapa de investigação.Due to the intensification of cooperation between China and the Lusophone nations, nowadays learning Portuguese is becoming increasingly fundamental in China. As a language which is radically different from their first language, Chinese learners usually manifest a number of difficulties in certain aspects while the cultural difference and limited opportunities to practice the target language outside the classroom also complicate their acquisition of Portuguese. Although some authors have evidenced the existence of problems in Chinese learners’ learning, they have not clarified practical solutions. In accordance with the characteristics of today’s students, who spend a lot of time on social media in their daily lives, we believe that the introduction of social tools can potentially be a reasonable approach to promote the learning of Portuguese. We focus on investigating the impact of using Weibo, a Chinese microblogging platform, on the writing skills of Chinese learners. We chose to apply a triangulation of methodologies to analyze the participation, motivation, posts, results of the two tests carried out before and after the activities and interviews with participants in order to obtain a comprehensive understanding of the potential of Weibo. Three interventions were conducted with the objectives of verifying the possibility of creating a collaborative learning community by using the selected tool and identifying the influence of the interaction between Chinese and Portuguese learners and between Chinese learners and a native teacher in relation to Portuguese writing skills. According to the results achieved, besides revealing a relatively positive motivation and satisfaction, participants generally demonstrate better behavior regarding verbal agreement and spelling and some of them also manifest an evident progress in using verb tenses and modes and nominal number agreement, while the participants of the last intervention score generally higher on reading comprehension than non-participants. These results highlight the possibility and efficiency of applying Weibo with Chinese speakers who are learning Portuguese. We believe that the introduction of a social network with an appropriate strategy can bring positive influences and it is worthy of further research and structured application in teaching practice as a future step.Programa Doutoral em Multimédia em Educaçã

    Trust Me, I’m an Influencer! - A Comparison of Perceived Trust in Human and Virtual Influencers

    Get PDF
    Influencers in social media are often perceived as a trusted source for many people which is why companies increasingly promote their products through them. However, influencers can also cause reputational damage for a brand. Virtual (computer-generated) influencers can be used to minimize these risks and to better tailor content to a target group of a company. As trust is one success factor of online marketing, we examine differences in the perception of trust in human and virtual influencers. In a first online survey study, we presented N = 112 participants the content of human and virtual influencers, published on Instagram. Preliminary findings reveal that although participants were often unsure whether the presented influencer was human or computer-generated, perceived trust, social presence, and humanness was consistently rated higher for human influencers. To gain deeper insights into potential, unconscious decision conflicts which can determine trust evaluations, a follow-up neuroimaging study is discussed
