One of the most remarkable phenomena in nature is mimicry,in which one species (the mimic) evolves to imitate the phenotype ofanother species (the model). Several reasons for the origin of mimicryhave been proposed, but no definitive conclusion has been found yet. Inthis paper, we test several of these hypotheses through an agent based coevolutionarymodel. In particular, we consider two possible alternatives:(1) Deception, in which mimics evolve to imitate the phenotype of modelsthat predators avoid to eat, and (2) Coincidence, in which models evolvea warning color to avoid predation, which coincidentally benefits themimics. Our agent-based simulation shows that both these hypothesesare plausible origins for mimicry, but also that once a mimicry situationhas been established through coincidence, mimics will take advantage ofthe possibility for deception as well.

In de afgelopen jaren hebben technologische ontwikkelingen de aard van dienstverlening ingrijpend veranderd (Huang & Rust, 2018). Technologie wordt steeds vaker ingezet om menselijke servicemedewerkers te vervangen of te ondersteunen (Larivière et al., 2017; Wirtz et al., 2018). Dit stelt dienstverleners in staat om meer klanten te bedienen met minder werknemers, waardoor de operationele efficiëntie toeneemt (Beatson et al., 2007). Deze operationele efficiëntie leidt weer tot lagere kosten en een groter concurrentievermogen. Ook voor klanten kan de inzet van technologie voordelen hebben, zoals betere toegankelijkheid en consistentie, tijd- en kostenbesparing en (de perceptie van) meer controle over het serviceproces (Curran & Meuter, 2005). Mede vanwege deze beoogde voordelen is de inzet van technologie in service-interacties de afgelopen twee decennia exponentieel gegroeid. De inzet van zogenaamde conversational agents is een van de belangrijkste manieren waarop dienstverleners technologie kunnen inzetten om menselijke servicemedewerkers te ondersteunen of vervangen (Gartner, 2021). Conversational agents zijn geautomatiseerde gesprekspartners die menselijk communicatief gedrag nabootsen (Laranjo et al., 2018; Schuetzler et al., 2018). Er bestaan grofweg drie soorten conversational agents: chatbots, avatars, en robots. Chatbots zijn applicaties die geen virtuele of fysieke belichaming hebben en voornamelijk communiceren via gesproken of geschreven verbale communicatie (Araujo, 2018;Dale, 2016). Avatars hebben een virtuele belichaming, waardoor ze ook non-verbale signalen kunnen gebruiken om te communiceren, zoals glimlachen en knikken (Cassell, 2000). Robots, ten slotte, hebben een fysieke belichaming, waardoor ze ook fysiek contact kunnen hebben met gebruikers (Fink, 2012). Conversational agents onderscheiden zich door hun vermogen om menselijk gedrag te vertonen in service-interacties, maar op de vraag ‘hoe menselijk is wenselijk?’ bestaat nog geen eenduidig antwoord. Conversational agents als sociale actoren Om succesvol te zijn als dienstverlener, is kwalitatief hoogwaardige interactie tussen servicemedewerkers en klanten van cruciaal belang (Palmatier et al., 2006). Dit komt omdat klanten hun percepties van een servicemedewerker (bijv. vriendelijkheid, bekwaamheid) ontlenen aan diens uiterlijk en verbale en non verbale gedrag (Nickson et al., 2005; Specht et al., 2007; Sundaram & Webster, 2000). Deze klantpercepties beïnvloeden belangrijke aspecten van de relatie tussen klanten en dienstverleners, zoals vertrouwen en betrokkenheid, die op hun beurt intentie tot gebruik, mond-tot-mondreclame, loyaliteit en samenwerking beïnvloeden (Hennig-Thurau, 2004; Palmatier et al., 2006).Er is groeiend bewijs dat de uiterlijke kenmerken en communicatieve gedragingen (hierna: menselijke communicatieve gedragingen) die percepties van klanten positief beïnvloeden, ook effectief zijn wanneer ze worden toegepast door conversational agents (B.R. Duffy, 2003; Holtgraves et al., 2007). Het zogenaamde ‘Computers Als Sociale Actoren’ (CASA paradigma vertrekt vanuit de aanname dat mensen de neiging hebben om onbewust sociale regels en gedragingen toe te passen in interacties met computers, ondanks het feit dat ze weten dat deze computers levenloos zijn (Nass et al., 1994). Dit kan verder worden verklaard door het fenomeen antropomorfisme (Epley et al., 2007; Novak & Hoffman, 2019). Antropomorfisme houdt in dat de aanwezigheid van mensachtige kenmerken of gedragingen in niet-menselijke agenten, onbewust cognitieve schema's voor menselijke interactie activeert (Aggarwal & McGill, 2007; M.K. Lee et al., 2010). Door computers te antropomorfiseren komen mensen tegemoet aan hun eigen behoefte aan sociale verbinding en begrip van de sociale omgeving (Epley et al., 2007; Waytz et al., 2010). Dit heeft echter ook tot gevolg dat mensen cognitieve schema’s voor sociale perceptie toepassen op conversational agents.

From the publisher: "Background: The introduction of whole new foods in a population may lead to sensitization and food allergy. This constitutes a potential public health problem and a challenge to risk assessors and managers as the existing understanding of the pathophysiological processes and the currently available biological tools for prediction of the risk for food allergy development and the severity of the reaction are not sufficient. There is a substantial body of in vivo and in vitro data describing molecular and cellular events potentially involved in food sensitization. However, these events have not been organized in a sequence of related events that is plausible to result in sensitization, and useful to challenge current hypotheses. The aim of this manuscript was to collect and structure the current mechanistic understanding of sensitization induction to food proteins by applying the concept of adverse outcome pathway (AOP). Main body: The proposed AOP for food sensitization is based on information on molecular and cellular mechanisms and pathways evidenced to be involved in sensitization by food and food proteins and uses the AOPs for chemical skin sensitization and respiratory sensitization induction as templates. Available mechanistic data on protein respiratory sensitization were included to fill out gaps in the understanding of how proteins may affect cells, cell-cell interactions and tissue homeostasis. Analysis revealed several key events (KE) and biomarkers that may have potential use in testing and assessment of proteins for their sensitizing potential. Conclusion: The application of the AOP concept to structure mechanistic in vivo and in vitro knowledge has made it possible to identify a number of methods, each addressing a specific KE, that provide information about the food allergenic potential of new proteins. When applied in the context of an integrated strategy these methods may reduce, if not replace, current animal testing approaches. The proposed AOP will be shared at the www.aopwiki.org platform to expand the mechanistic data, improve the confidence in each of the proposed KE and key event relations (KERs), and allow for the identification of new, or refinement of established KE and KERs."

Emotions are a key component of tourism experiences, as emotions make experiences more valued and more memorable. Peak-and-end-theory states that overall experience evaluations are best predicted by the emotions at the most intense and final moments of an experience. Peak-and-end-theory has mostly been studied for relatively simple experiences. Recent insights suggest that peak-and-end-theory does not necessarily hold for tourism experiences, which tend to be more heterogeneous and multi-episodic in nature. Through the novel approach of using electrophysiological measures in combination with experience reconstruction, the applicability of the peak-and-end-theory to the field of tourism is addressed by studying a musical theatre show in a theme park resort. Findings indicate that for a multi-episodic tourism experience, hypotheses from the peak-and-end-theory are rejected for the experience as a whole, but supported for individual episodes within the experience. Furthermore, it is shown that electrophysiology sheds a new light on the temporal dynamics of experience

Biomimicry education is grounded in a set of natural design principles common to every known lifeform on Earth. These Life’s Principles (LPs) (cc Biomimicry 3.8), provide guidelines for emulating sustainable strategies that are field-tested over nearly four billion years of evolution. This study evaluates an exercise for teaching LPs to interdisciplinary students at three universities, Arizona State University (ASU) in Phoenix, Arizona (USA), College of Charleston (CofC) in Charleston, South Carolina (USA) and The Hague University of Applied Sciences (THUAS) in The Hague (The Netherlands) during the spring 2021 semester. Students researched examples of both biological organisms and human designs exhibiting the LPs. We gauged the effectiveness of the exercise through a common rubric and a survey to discover ways to improve instruction and student understanding. Increased student success was found to be directly linked to introducing the LPs with illustrative examples, assigning an active search for examples as part of the exercise, and utilizing direct assessment feedback loops. Requiring students to highlight the specific terms of the LP sub-principles in each example is a suggested improvement to the instructions and rubric. An iterative, face-to-face, discussion-based teaching and learning approach helps overcome minor misunderstandings. Reiterating the LPs throughout the semester with opportunities for application will highlight the potential for incorporating LPs into students’ future sustainable design process.

Our planet’s ecology and society are on a collision course, which manifests due to a contradiction in the assumptions of unlimited material growth fueling the linear economic paradigm. Our closed planetary ecosystem imposes confined amounts of space and a finite extent of resources upon its inhabitants. However, practically all the economic perspectives have been defiantly neglecting these realities, as resources are extracted, used and disposed of reluctantly (Ellen MacArthur Foundation 2015). The circular economy attempts to reconcile the extraction, production and usage of goods and resources with the limited availability of those resources and nature’s regenerative capabilities This perspective entails a shift throughout the supply chain, from material science (e g non-toxic, regenerative biomaterials) to novel logistical systems (e g low-carbon reverse logistics). Because of this, the circular economy is often celebrated for its potential environmental benefits and its usefulness as a blueprint for sustainable development (Ellen MacArthur Foundation 2017). Unfortunately, the promise of the circular economy aiming at enhanced sustainability through restorative intent and design (McDonough & Braungart 2010), is often inhibited by institutional barriers posed by the current linear economy of take, make, use and waste (Ghisellini et al. 2016). Underlying those barriers our cultural paradigm celebrates consumerism, exponential growth and financial benefit instead of human values such as diversity, care and trust. Based on a mapping exercise of the circular economy discourse in the Netherlands and an overview of international (academic) literature (Van den Berg 2020) supplemented with collaborative co-creation sessions, visiting events, conferences, giving talks and classes, we have defined a gap leading to the focus of the Professorship. First, we highlight the importance of a process approach in studying the transition from a linear to a circular economy, which is why we use the verb ‘entrepreneuring’ as it indicates the movement we collectively need to make. The majority of work in the field is based on start-ups and only captures snapshots while longitudinal and transition perspectives - especially of larger companies - are missing (Merli et al. 2019; Geissdoerfer et al. 2018; Bocken et al. 2014). We specifically adopt an entrepreneurship-as-practice lens (Thompson, Verduijn & Gartner 2020), which allows us to trace the doings – as opposed to only the sayings - of organizations involved in circular innovation. Such an approach also enables us to study cross-sector and interfirm collaboration, which is crucial to achieve ecosystem circularity (Raworth 2019). As materials flow between actors in a system, traditional views of ‘a value chain’ slowly make way for an ecosystem or value web perspective on ‘organizing business’. We summarize this first theme as ‘entrepreneurship as social change’ broadening dominant views of what economic activity is and who the main actors are supposed to be (Barinaga 2013; Calás, Smircich & Bourne 2009; Steyaert & Hjorth 2008; Nicholls 2008). Second, within the Circular Business Professorship value is a big word in two ways. First of all, we believe that a transition to a circular economy is not just a transition of materials, nor technologies - it is most of all a transition of values We are interested in how people can explore their own agency in transitioning to a circular economy thereby aligning their personal values with the values of the organization and the larger system they are a part of Second, while circularity is a broad concept that can be approached through different lenses, the way in which things are valued and how value is created and extracted lies at the heart of the transition (Mazzucato 2018). If we don’t understand value as collectively crafted it will be very hard to change things, which is why we specifically focus on multiplicity and co-creation in the process of reclaiming value, originating from an ethics of care Third, sustainability efforts are often concerned with optimization of the current – linear – system by means of ecoefficient practices that are a bit ‘less bad’; using ’less resources’, causing ‘less pollution’ and ‘having less negative impact’. In contrast, eco-effective practices are inherently good, departing from the notion of abundance: circular thinking celebrates the abundance of nature’s regenerative capacities as well as the abundance of our imagination to envision new realities (Ellen MacArthur Foundation 2015). Instead of exploiting natural resources, we should look closely in order to learn how we can build resilient self-sustaining ecosystems like the ones we find in nature. We are in need of rediscovering our profound connection with and appreciation of nature, which requires us to move beyond the cognitive and employ an aesthetic perspective of sustainability This perspective informs our approach to innovating education: aesthetics can support deep sustainability learning (Ivanaj, Poldner & Shrivastava 2014) and contribute to facilitating the circular change makers of the future. The current linear economy has driven our planet’s ecology and society towards a collision course and it is really now or never: if we don’t alter the course towards a circular economy today, then when? When will it become urgent enough for us to take action? Which disaster is needed for us to wake up? We desperately need substitutes for the current neo-liberal paradigm, which underlies our linear society and prevents us from becoming an economy of well-being In Entrepreneuring a regenerative society I propose three research themes – ‘entrepreneurship as social change’, ‘reclaiming value’ and ‘the aesthetics of sustainability’ – as alternative ways of embracing, studying and co-creating such a novel reality.

The methodology of biomimicry design thinking is based on and builds upon the overarching patterns that all life abides by. “Cultivating cooperative relationships” within an ecosystem is one such pattern we as humans can learn from to nurture our own mutualistic and symbiotic relationships. While form and process translations from biology to design have proven accessible by students learning biomimicry, the realm of translating biological functions in a systematic approach has proven to be more difficult. This study examines how higher education students can approach the gap that many companies in transition are struggling with today; that of thinking within the closed loops of their own ecosystem, to do good without damaging the system itself. Design students should be able to assess and advise on product design choices within such systems after graduation. We know when tackling a design challenge, teams have difficulties sifting through the mass of information they encounter, and many obstacles are encountered by students and their professional clients when trying to implement systems thinking into their design process. While biomimicry offers guidelines and methodology, there is insufficient research on complex, systems-level problem solving that systems thinking biomimicry requires. This study looks at factors found in course exercises, through student surveys and interviews that helped (novice) professionals initiate systems thinking methods as part of their strategy. The steps found in this research show characteristics from student responses and matching educational steps which enabled them to develop their own approach to challenges in a systems thinking manner. Experiences from the 2022 cohort of the semester “Design with Nature” within the Industrial Design Engineering program at The Hague University of Applied Sciences in the Netherlands have shown that the mixing and matching of connected biological design strategies to understand integrating functions and relationships within a human system is a promising first step.

This article explores how concern about animal welfare and animal rights relates to ecological citizenship by discussing student assignments written about the Dutch Party for Animals or PvdD. ‘Animal welfare’, ‘animal rights’, and ‘ecological citizenship’ perspectives offer insights into strategic choices of eco-representatives and animal rights/welfare advocates as well as educators. The assignments balance animal issues with socio-economic ones, explore the relationship between sustainability and ethics, and attribute responsibility for unsustainable or unethical practices. Analysis of student assignments reveals nuanced positions on the anthropocentrism-ecocentrism continuum, showing students’ ability to critically rethink their place within larger environmental systems. Some students demonstrated compassion for nonhumans, indicating that biophilia is evenly distributed among different groups of students. This article finds that fostering pro-environmentalism and animal welfare or rights requires the deepening of the debate contesting but also connecting key issues in sustainability and ethics. This analysis can be valuable for political parties representing nonhumans, or for education practitioners in getting students to think about the challenges in human-environment relationships and for advancing support for ecodemocracy. https://ro.uow.edu.au/asj/vol8/iss1/10/ LinkedIn: https://www.linkedin.com/in/helenkopnina/
