Résumé :
Purpose The purpose of the paper is to examine the role of trust and distrust in social networks within the entrepreneurial ecosystem and to develop a conceptual scheme of the impact of trust and distrust on productive and unproductive entrepreneurship. Design/methodology/approach This study develops a conceptual scheme, founded on the social capital and resource-based view of a firm, by exploring the impact of trust and distrust on entrepreneurial behavior in a social network. Findings As the paper indicates, trust within an entrepreneurial ecosystem has a positive impact on productive entrepreneurship, while distrust within the ecosystem is expected to be unproductive and destructive (or potentially illegal) to an economy. Research limitations/implications The research implication of this paper is that it connects levels of trust and distrust within the ecosystem to the type of the behavior exhibited by entrepreneurs leading either to productive or unproductive entrepreneurial endeavors. As this study is based on the theoretical review resulting in a conceptual scheme, it requires further investigation of proposed interactions. Practical implications This paper offers strategic alternatives for entrepreneurs seeking to enhance future endeavors by strengthening trust within social networks for the mutual benefits of the ecosystem and businesses within it. Social implications This study highlights the importance of two social constructs of trust and distrust in maintaining existing and developing future ecosystems. It also reviews potential outcomes of entrepreneurial behavior and their impact on economies. Originality/value This research examines both trust and distrust (two separate social constructs) as significant predictors of future outcomes in the entrepreneurial ecosystem that go beyond productive entrepreneurship.

Résumé :
Within the innovation ecosystem literature, scholars have considered governance mechanisms as an important instrument for focal entities to mitigate the risks of opportunistic behaviour. Scholars have not focused yet on how these mechanisms work. In the alliance literature, governance mechanisms have been extensively researched and described. As innovation ecosystems are a subset of alliances, constructs from the alliance literature are used to understand how governance mechanisms are employed by the focal entity within innovation ecosystems. Scholars have also considered the importance of partner alignment for successful innovations. To mitigate the risks of opportunistic behaviour and to align partners, this research has focused on understanding how the focal entity uses governance mechanisms to influence partner alignment. Based on an exploratory multiple case study research, this research has found a list of partner stimulators, like for example leadership and expectation management, that influence the effectiveness of governance mechanisms used by focal entities in aligning partners. When partner alignment stimulators are present, the effectiveness of governance mechanisms is enhanced and partners feel more aligned. We have also developed a model that explains the relation between partner alignment stimulators, governance mechanisms, and partner alignment. In addition, we have found that constructs from the alliance literature can be applied to an innovation ecosystem setting when partner alignment stimulators are considered in addition to governance mechanisms. We contribute to the innovation ecosystem literature by explicitly considering partner alignment stimulators that influence the relation between governance mechanisms and partner alignment. Future research could focus on using quantitative methods to strengthen the findings of this research.

Résumé :
The use of eHealth and healthcare services are becoming increasingly common across networks and ecosystems. Identifying the quality and health impact of these services is a big problem that in many cases it is difficult determine. Health ecosystems are seldom designed with privacy and trust in mind, and the service user has almost no way of knowing how much trust to place in the service provider and other stakeholders using his or her personal health information (PHI). In addition, the service user cannot rely on privacy laws, and the ecosystem is not a trustworthy system. This demonstrates that, in real life, the user does not have significant privacy. Therefore, before starting to use eHealth services and subsequently disclosing personal health information (PHI), the user would benefit from tools to measure the level of privacy and trust the ecosystem can offer. For this purpose, the authors developed a solution that enables the service user to calculate a Merit of Service (Fuzzy attractiveness rating (FAR)) for the service provider and for the network where PHI is processed. A conceptual model for an eHealth ecosystem was developed. With the help of heuristic methods and system and literature analysis, a novel proposal to identify trust and privacy attributes focused on eHealth was developed. The FAR value is a combination of the service network’s privacy and trust features, and the expected health impact of the service. The computational Fuzzy linguistic method was used to calculate the FAR. For user friendliness, the Fuzzy value of Merit was transformed into a linguistic Fuzzy label. Finally, an illustrative example of FAR calculation is presented.

Résumé :
Based on a bibliographic study, this contribution explores the conditions of birth of innovation Ecosystems (IEs). The main purpose is to give an overview of the current thinking on the theme. The conceptual models drawn from the literature including the factors of birth of an ecosystem constitute the result of this paper work. The main ambition is the study of the possibility of setting up an IE with analysis of the existing situation. Thanks to an exploratory study, we were able to proof that an ecosystem community come into existence through both emergent and deliberate strategies. Three major phases characterize ecosystems arrival: knowledge ecosystem (KE), IE and business ecosystem (BE). During the birth phase, many factors are likely to enhance its advent, in particular: the diversity of ecosystem’s actors, the sharing of knowledge between members, the training for collaborative and inter-organizational skills and the establishment of a climate of trust within the community.

Résumé :
Purpose: Organizations evolve from using and governing data internally towards the exchange of data in multi-organizational data ecosystems. The purpose of this research is to determine a business model framework for actors operating in and/or entering a data ecosystem. Methodology: To determine a business model framework in data ecosystems. an analysis was made based on how the research fields of “business models”, “data governance”, “data ecosystems”, “data sharing”, “business ecosystem” complement each other. A business model framework was created, which was applied to three use case studies in the field of Smart Cities and Urban Digital Twins: The Helsinki Digital Twin, the Rotterdam Digital Twin, and the Smart Retail Dashboard in Flanders. Findings: The business model of actors in a data ecosystem is determined by value and control factors. Value is determined by the capability to create value through the exchange of data in the ecosystem, and to capture value through revenue (sharing) models and cost (sharing) models. Control is determined by ecosystem control. Governance models on the ecosystem level are required to enable the collaboration and to ensure trust to allow for the willingness to share data. Additionally, data governance on an ecosystem level is required, enabling the data exchange between the actors. Research Limitations: The model was applied to three use cases in Smart Cities and Urban Digital Twins. Consequently, the data ecosystems concern a high presence of public actors, yet also includes private companies. The applicability needs to be identified in other sectors in further research. Additionally, as the scope of the study was on business models, data governance, data-sharing and data ecosystems, abstraction was made of fields of study beyond these topics. Value and practical implications: The Data Ecosystem Business Model framework can serve as a guideline for organizations entering a data ecosystem, as well as for actors aiming to establish novel data ecosystems. Additionally, the framework can serve as a high-level overview for further research into the field of business models in data ecosystems.

Résumé :
Despite considerable research highlighting the significance of relational governance in inter-organizational relationships, few have involved the connections between relational governance and innovation ecosystems. This study explores this issue to discover the influential mechanisms of relational governance in innovation ecosystem co-evolution. Building an evolutionary game model, we embody trust and reciprocity (two dominance of relational governance) into co-evolutionary relationships of an innovation ecosystem composed of focal firms, research institutes, customers, and governments, and discuss how relational governance affects innovation strategies of actors. Moreover, the impacts of benefit distribution are also examined. We reveal that (1) focal firms and governments prefer cooperative strategies; (2) reciprocity and trust foster cooperation; increasing benefit distribution drives all actors to collaborate except research institutes; (3) governments finitely encourage cooperation through regulation; and (4) the power of relational governance is restricted due to the below-the-average strategies of customers and research institutes and the neutralizing effects of benefits. Our findings offer a complementary and novel framework for relational governance and extend a deeper understanding of innovation ecosystem studies.

Résumé :
The Internet of Things is enriching our life with an ecosystem of interconnected devices. Object cooperation allows us to develop complex applications in which each node contributes one or more services. Therefore, the information moves from a provider to a requester node in a peer-to-peer network. In that scenario, trust management systems (TMSs) have been developed to prevent the manipulation of data by unauthorized entities and guarantee the detection of malicious behaviour. The community concentrates effort on designing complex trust techniques to increase their effectiveness; however, two strong assumptions have been overlooked. First, nodes could provide the wrong services due to malicious behaviours or malfunctions and insufficient accuracy. Second, the requester nodes usually cannot evaluate the received service perfectly. For this reason, a trust system should distinguish attackers from objects with poor performance and consider service evaluation errors. Simulation results prove that advanced trust algorithms are unnecessary for such scenarios with these deficiencies.

Résumé :
The development of blockchain technology promotes the evolution of the industrial ecosystem, and the value co-creation in the ecosystem has become an important factor for the sustainable and coordinated development of the blockchain industry ecosystem. By answering the question of how governance mechanisms affect the value co-creation of the blockchain industry ecosystem, this paper aims to clarify the realization mechanism of value co-creation of the blockchain industry ecosystem. Based on the transaction cost theory and social exchange theory, the governance mechanisms of the blockchain industry ecosystem are divided into contract governance and trust governance. The system dynamics method is used to analyze the causality of the effect of governance mechanisms on value co-creation of the blockchain industry ecosystem, the model of system flow chart is established, and Vensim PLE software is used to perform simulation and sensitivity analyses of the model. The results show that: both contract governance and trust governance can positively affect the value co-creation of the blockchain industry ecosystem; due to the existence of bounded rationality, compared with contract governance, trust governance has a more significant impact on system resource innovation and value co-creation; there is a co-existence effect among contract governance and trust governance, and compared with the single effect, the co-existence effect of two can promote the value co-creation process of the blockchain industry ecosystem more actively. The research results reveal the internal laws of the value co-creation and provide valuable insights into the exploitation of governance mechanisms to facilitate effectively the value creation of the blockchain industry ecosystem.

Résumé :
2014 - 2015
The Internet is an extraordinary communications medium but it is not free from problems that are limiting its potential further development. In this dissertation we analyze and address some of the issues that make it an unsafe and unreliable place and we exhibit the most difficult issues that, as soon as possible, would deserve to be resolved such as: the uncertainty of the identities; the almost complete lack of privacy and of guarantees on the reliability of the counterparts (i.e., the lack of trust among people); the lack of control and ownership of the information regarding a person or a company; the lack of specific information about service providers; the exploitation of anonymity to perform malicious actions. These issues mainly arise from the very nature of the Internet which is a deregulated place where users have the possibility to act and communicate in total freedom while keeping the anonymity. However, these aspects should, in our opinion, be balanced with the protection of the fundamental users’ rights. The main goal of our research is to combine the positive aspects and the strengths of the Internet with the need to introduce environments or areas where users can enjoy greater mutual trust. To this aim, we proposed a solution to augment the Internet to make it a safer and more reliable place. Our proposal allows users to interact with higher security than at present and to have better guarantees on the respect for their rights and their needs. In other words, based on the above reasons, in this work our objective is the design of a comprehensive framework aimed at providing a trust area in the Internet that combines the online and offline world smoothly and seamlessly, including the best solutions in a single model. Our integrated and modular model is called Trust Ecosystem (TEco) where “ecosystem” means an environment where the entities (e.g., users and online services) preserve the system and comply with fixed rules, are proactive and responsive as each of them, using a reward-punishment mechanism (feedback), contribute to the success of the system and, consequently, to their own benefit. The TEco was built by integrating different innovative systems. It is a Internetbased area in which users: own a Trusted Digital Identity to authenticate keeping anonymity; establish Inter Pares Interactions based on contracted agreements and knowing each other’s reputation; can be the owners of the information they produce and protect their privacy. The coexistence of these features makes the TEco a trust area. In fact, users can mutually trust, as they are all identifiable, their reputation is known and while interacting, they can bargain conditions with law effectiveness. Furthermore, depending on their needs and the demands of others, users can decide which information to disseminate, protecting their privacy or maintaining complete anonymity. The TEco has been conceived without “upheavals” of the current Internet and for this reason the TEco can develop in parallel with it and, in any case, they can coexist. In fact, the users will not be forced to drastically change the way in which they normally use both Internet services and Web browsing. In our view, to obtain a Trust Area there is the need of effective Trust and Reputation systems. Although new Trust, Reputation and Recommendation (TRR) models are continuously proposed in literature, they lack shared bases and goals. For this reason, in this work we pay special attention to the problems related to Trust and Reputation management that are among the most controversial issues of the Internet. So, we address trust and reputation in all their aspects and we define an innovative meta model to facilitate the definition and standardization of a generic TRR model. Following the meta model, researchers in the field will be able to define standard models, compare them with other models and reuse parts of them. A standardization is also needed to determine which properties should be present in a TRR model. In accordance with the objectives we were seeking, following our meta model we have: defined a pre-standardized TRR model for e-commerce; identified the fundamental concepts and the main features that contribute to form trust and reputation in that domain; respected the dependence on the context/role of trust and reputation; aggregated only homogeneous trust information; listed and shown how to defend from the main malicious attacks. Lastly, in this work, we also discuss the feasibility of the Trust Ecosystem, the compatibility with the current Internet and the things to do for putting it into practice. For this purpose, we show some scenarios that also highlight and make advantages and potentiality of the TEco fully understandable. In the future, the TEco may also act as a “field of comparison” and facilitate scientific communication in the sector and, like a digital ecosystem, can play the role of a unification “umbrella” over significant, challenging and visionary computing approaches that emerge in parallel.

Internet é uno straordinario strumento di comunicazione ma non é immune da criticitá che ne stanno limitando l’ulteriore potenziale sviluppo. In questa dissertazione analizziamo e affrontiamo alcune delle problematiche che lo rendono un luogo poco sicuro e inaffidabile ed esponiamo le questioni piú spinose che meriterebbero al piú presto di essere risolte come: l’incertezza dell’identitá, la quasi totale mancanza di privacy e di garanzie sull’affidabilitá delle controparti (cioé la mancanza di fiducia tra le persone), la mancanza di controllo e proprietá delle informazioni riguardo ad una persona o ad una compagnia, la mancanza di specifiche informazioni riguardo i service provider, lo sfruttamento dell’anonimato per eseguire azioni dolose. Tali problematiche scaturiscono principalmente dalla natura stessa dell’attuale Internet che é un luogo deregolamentato in cui gli utenti hanno la possibilitá di agire e comunicare in totale libertá mantenendo l’anonimato. Tuttavia, tali aspetti andrebbero, a nostro avviso, bilanciati con la salvaguardia dei diritti fondamentali degli utenti. L’obiettivo principale della nostra ricerca é stato quello di coniugare gli aspetti positivi e i punti di forza dell’attuale Internet con la necessitá di introdurre ambienti o zone in cui gli utenti possano godere di una maggiore fiducia reciproca. A tal proposito abbiamo proposto una soluzione per aumentare l’Internet e per renderlo un posto piú sicuro e affidabile. La nostra proposta fa si che gli utenti possano interagire con maggiore sicurezza rispetto a quanto avviene attualmente ed avere maggiori garanzie sul rispetto dei propri diritti e delle proprie esigenze. In altre parole, per quanto detto finora, l’obiettivo di questo lavoro é la progettazione di un framework globale volto a fornire una trust area in Internet che unisca il mondo online e offline in modo fluido e senza soluzione di continuitá, includendo le migliori soluzioni in un unico modello. Il nostro modello integrato e modulare viene chiamato Trust Ecosystem (TEco) dove per “ecosystem” si intende un ambiente in cui le entitá (per esempio gli utenti e i servizi online) preservano il sistema e rispettano regole prefissate, sono proattive e reattive poiché ognuna di esse, utilizzando un meccanismo di premio-punizione (feedback), contribuisce al successo del sistema e, conseguentemente, al proprio beneficio. Il TEco é stato costruito integrando differenti ed innovativi sistemi. Esso é una Internet-based area in cui gli utenti: possiedono una Trusted Digital Identity per autenticarsi mantenendo l’anonimato, stabiliscono Inter Pares Interactions basate su un contratto concordato e conoscendo la reputazione di tutti gli altri, sono proprietari delle informazioni che producono e proteggono la loro privacy. La coesistenza di queste caratteristiche rende il TEco una trust area. Infatti gli utenti possono fidarsi reciprocamente poiché sono tutti identificabili, la loro reputazione é nota e mentre interagiscono, possono contrattare condizioni aventi forza di legge. Inoltre, in base alle loro necessitá e alle richieste degli altri, gli utenti possono decidere quali informazioni divulgare, proteggere la loro privacy o mantenere il completo anonimato. Il TEco é stato concepito senza richiedere sconvolgimenti dell’attuale Internet e per questa ragione puó svilupparsi in parallelo con esso e, in ogni caso, essi possono coesistere. Infatti, gli utenti non saranno obbligati a cambiare drasticamente il modo in cui essi normalmente usano i servizi Internet e il Web. A nostro avviso, per ottenere una Trust Area c’é bisogno di sistemi di Trust and Reputation systems efficaci. Sebbene nuovi Trust, Reputation and Recommendation (TRR) models vengano continuamente proposti in letteratura, essi mancano di basi e obiettivi condivisi. Per questa ragione, in questo lavoro abbiamo posto speciale attenzione ai problemi relativi alla Trust and Reputation management che sono tra le problematiche piú controverse di Internet. Per questo, abbiamo affrontato la trust e la reputation in tutti i loro aspetti e definito un innovativo meta model per facilitare la definizione e standardizzazione di un generico TRR model. Seguendo il nostro meta model, i ricercatori del settore potranno definire modelli standard, compararli con gli altri modelli e riusare parti di essi. Una standardizzazione é necessaria anche per determinare quali proprietá dovrebbero essere presenti in un TRR model. Conformemente agli obiettivi che ci eravamo proposti, seguendo il nostro meta model abbiamo: definito un TRR model per l’e-commerce pre-standardizzato, identificato i concetti fondamentali e le principali caratteristiche che contribuiscono a formare la trust e la reputation in quel dominio, rispettato la dipendenza della trust e della reputazione dal contesto/ruolo, aggregato solo trust information omogenee, elencato e mostrato come difendersi dai principali malicious attacks. Infine, in questo lavoro, discutiamo anche della fattibilitá del Trust Ecosystem, della compatibilitá con l’attuale Internet e le cose da fare per poterlo mettere in pratica. Per questo motivo, mostriamo anche alcuni scenari che evidenziano e rendono pienamente comprensibili i vantaggi e le potenzialitá del TEco. In futuro, il TEco potrebbe anche agire come un terreno di confronto e facilitare la comunicazione scientifica nel settore e, come un ecosistema digitale, puó giocare il ruolo di un "ombrello" unificante sugli approcci significativi, stimolanti e visionari che emergeranno in parallelo.

All were asked to reflect on their experience in managing change. They werethen encouraged to propose actions in face of the challenges of sustainability and the sustainable city,and react on a vision of the Sustainable City for Paris and its larger region. They expressed barriers tochallenges and to the vision proposed. And they also proposed ideas, expressed desires, opportunitiesand overall bridges for sustainability to be practically implemented. The findings presented theenterprises‟ interpretation of the concepts of trust and innovation. Reflecting on how the results couldcontribute to a transformation into a Sustainable City resulted in a practical list of actions. This pilotstudy showed a potential for sustainable development to emerge throughout the City through its mostimpactful yet promising actors, the small businesses.In order to contribute in building bridges between City and Nature, the exploration is inspired bysocial ecological research, looking for ways to harmonize the various elements and actors to transformcities into sustainable ones. The framework is mostly based on a business-inspired research design anda construct from the European Union Sustainable City challenges, resilience theory approaches and theFrench national strategy for sustainable development.

Résumé :
abstract: The increasing popularity of Twitter renders improved trustworthiness and relevance assessment of tweets much more important for search. However, given the limitations on the size of tweets, it is hard to extract measures for ranking from the tweet's content alone. I propose a method of ranking tweets by generating a reputation score for each tweet that is based not just on content, but also additional information from the Twitter ecosystem that consists of users, tweets, and the web pages that tweets link to. This information is obtained by modeling the Twitter ecosystem as a three-layer graph. The reputation score is used to power two novel methods of ranking tweets by propagating the reputation over an agreement graph based on tweets' content similarity. Additionally, I show how the agreement graph helps counter tweet spam. An evaluation of my method on 16~million tweets from the TREC 2011 Microblog Dataset shows that it doubles the precision over baseline Twitter Search and achieves higher precision than current state of the art method. I present a detailed internal empirical evaluation of RAProp in comparison to several alternative approaches proposed by me, as well as external evaluation in comparison to the current state of the art method.

Résumé :
Intact sagebrush communities in the Great Basin are rapidly disappearing due to invasion of non-native plants, large wildfires, and encroachment of pinyon pine and juniper woodlands. Land management options include the use of prescribed fire, grazing, herbicides and mechanical treatments to reduce the potential for wildfire and restore plant communities. Land managers in the region face a complex and interrelated set of ecological, economic, and social challenges to the implementation of these management practices. Effective restoration strategies require consideration of citizens in the region and their acceptance of management practices, as well as their trust in the agencies that implement them. This longitudinal panel study (2006-2010) examines the social acceptability of management options for rangeland restoration and public trust in agencies to carry out these options in three urban and three rural regions of the Great Basin. Most similar studies in this region have been largely place-based and cross-sectional, focusing on communities at one point in time. Results from this study can be used to evaluate the success of management programs, predict support for different treatments, determine the impact of agency outreach efforts, and identify important factors for building trust between communities and agencies across the region. The study uses data from a mail-back questionnaire sent to residents in 2006 and again in 2010. Overall, 698 respondents comprise the panel of interest. Results suggest landscape scale events such as wildfire, as well as agency management and outreach programs, had little influence on respondents' perceptions of agencies or management options over the study period. Several key findings have persisted throughout the study: (1) acceptance is high for the use of prescribed fire, grazing, felling, and mowing, but low for chaining and herbicide use, though there are (2) low levels of public trust and confidence in agencies to implement these management options, and (3) there are salient differences between the region's rural and urban residents with important implications for agency communication strategies. Most changes in response over the study period were subtle, though the direction and strength of these changes highlight noteworthy trends: (1) Great Basin residents are becoming more aware of key threats facing rangelands, (2) they seem more interested in having a role in making management decisions, and (3) they are slightly more positive about their interactions with agency personnel. Finally, findings suggest many residents have had little experience with agency outreach programs. Trust and confidence in management agencies are key factors in garnering support for restoration activities. While knowledge of management activities and confidence in managers' ability to competently implement them certainly play a role, findings strongly suggest sincerity factors (e.g., good communication or the perception that agencies share citizens' goals, thoughts, or values) have the greatest influence on acceptance of management practices in the Great Basin. Results suggest it would be beneficial for agencies to take a more active role in building trust with residents across the region. Differing levels of knowledge and interest, as well as different concerns, found among rural and urban residents highlight the need to tailor outreach strategies for use in specific communities.

Résumé :
Zahlungen für Ökosystemdienstleistungen (Payments for Ecosystem Services – PES) und auktionsbasierte Vergabeverfahren sind ein wichtiges und innovatives Instrument im Kampf gegen den fortwährenden Verlust von biologischer Vielfalt. Basierend auf einem Vertrag zwischen einem Leistungserbringer und einem öffentlichen oder privaten Leistungsempfänger, der die Naturschutzleistung entlohnt, können bestimmte Vorgaben der Landschaftspflege oder der agrarwirtschaftlichen Bearbeitung verbindlich festgelegt werden. Die Vorteile von PES liegen in dem direkten monetären Anreiz zur Bereitstellung von Naturschutzleistungen und zudem in der Möglichkeit, ein Niveau an Umweltschutz und –qualität jenseits des von der Umweltgesetzgebung sichergestellten Mindestniveaus zu implementieren. Der Nachteil liegt in der hohen Informationsasymmetrie in der Vertragsbeziehung, welche einerseits dem Umweltgut als Vertragsgegenstand und andererseits der Natur ökonomischen Handelns geschuldet ist. Thema dieser Dissertation ist die Analyse der interdependenten Beziehung von Kompetitivität und Vertragserfüllung und das Aufzeigen der Relevanz von Vertrauen und Reziprozität in Verträgen über Umweltgüter. Auf diese Weise leistet sie einen Beitrag zu der umfangreichen und multidisziplinären Literatur über Zahlungen für Ökosystemdienstleistungen und Naturschutzauktionen. Während der vergangenen 25 Jahre habe Praktiker und Wissenschaftler unser Verständnis der Funktionsweise von Ausschreibungen zur Allokation von Zahlungen für Ökosystemdienstleistungen konstant verbessert und erweitert. Ein Großteil der Forschungsaktivität war jedoch auf die Auktionsmetrik und das Bieterverhalten gerichtet, wohingegen die resultierende Vertragsbeziehung zwischen Programmverwaltern (den Käufern) und Landbesitzern (den Ausführenden) weitgehend unbeachtet blieb. Wie in dieser Dissertation bewiesen wird, ist jedoch genau diese Beziehung der Schlüssel für ein erfolgreiches marktbasiertes Naturschutzprogramm. In der vorliegenden Arbeit wird in drei Artikeln argumentiert, dass Vertrauen und Reziprozität für die Überwindung von asymmetrischer Information in kompetitiv alloziierten PES-Verträgen von herausragender Bedeutung sind. Anhand eines für diese Arbeit entwickelten, zweistufigen experimentellen Testszenarios wird der Entscheidungsprozess in der inversen Auktion und in der anschließenden Vertragserfüllung in der kontrollierten Laborumgebung simuliert. In einem ersten Experiment kann auf Basis dieses Untersuchungsdesigns gezeigt werden, dass die Informations- und Anreizkonstellation in Naturschutzauktionen ein erhöhtes Risiko für vorvertragliche adverse Selektion, opportunistisches Verhalten bei Vertragserfüllung und somit suboptimale Ergebnisse birgt. Das Marktversagen kann jedoch durch eine vertrauensstiftende Institution, wie zum Beispiel Kommunikation zwischen Käufern und Verkäufern, verhindert werden. Persönliche Interaktion veranlasst Marktteilnehmer ihr individuell-rationales Verhalten zugunsten einer sozial-verträglicheren Verhaltensweise zu ändern. Dabei entsteht ein erhebliches Potential für die Bilateralisierung der Vertragsbeziehungen. Ein zweites Experiment verdeutlicht jedoch, wie wichtig vertrauensbasierte Vertragsbeziehungen insbesondere in Bereitstellungsumgebungen sind, die stark von externen, stochastischen Einflüssen verzerrt werden können. Ohne das nötige Vertrauen bricht die Kooperation in einem derartigen Szenario fast vollständig zusammen. Schließlich lässt der systematische Vergleich der Ergebnisse aus beiden Experimenten in einem dritten Aufsatz keinen Zweifel daran, dass stabile Langzeitvertragsbeziehungen in auktionsbasierten Vertragsnaturschutzprogrammen gefördert und nicht verhindert werden sollten. Langzeitverträge sind randomisierten Kurzzeitverträgen aus der Perspektive des Naturschutzes aber auch hinsichtlich der Kosteneffektivität überlegen. Daher liegt eine wesentliche Herausforderung für Programmentwickler darin, einerseits die Bildung von ausreichend Sozialkapital zu ermöglichen und andererseits faire Markt- und Vergabestrukturen zu erhalten.

Résumé :
M.Sc. (Information Technology)
In Africa, the economy is largely dominated by SMMEs that represent 90% of private businesses and contribute to more than 50% of employment and GDP. However, these SMMEs struggle to sustain their businesses in the current economic climate. To address this, advancements in mobile and cloud technology introduce new possibilities such as digital business ecosystems to support environment where small, micro, and medium enterprises can interoperate. The fundamental challenge for SMMEs in a digital business ecosystem is the selection of transaction partners. SMMEs are interested to transact with other SMMEs that will benefit their business through successful transactions. This leads to the sustainability and growth of SMMEs and consequently the economy. However, not all SMMEs behave as predicted and therefore, being able to trust another SMME in the digital business ecosystem is important. Trust is an essential part of business and personal life. The social nature of trust makes trust very personalised and for each individual, trust is interpreted, understood and perceived according to past experience and social behaviour. These factors are largely influenced by cultural norms and behaviours that individuals conform to. In African and some other regions, collectivist cultural norms and behaviours are common whereas in Westernised regions, individualist cultures are common. Therefore, it is not enough to just consider trust from a technical perspective but also from a cultural perspective. For small businesses in Africa and other regions in the world, this is especially true. Compared to larger companies in developed economies, SMMEs in Africa are more informal and operate in a more personal manner. This implies that trust decisions are largely influence an owner or employee’s cultural norms and behaviour. The research conducted in this dissertation proposes a trust model, known as Trustcv that supports the cultural norms and behaviours of collectivist cultures for trust in a digital business ecosystem. Digital business ecosystems, trust, culture and social network analysis provide the literature foundation for Trustcv. The effectiveness of Trustcv is measured through simulations of a digital business ecosystem in Africa, which provides interesting results compared to an existing trust model. The results indicate that Trustcv could be used to support trust in collectivist digital business ecosystems used by collectivist cultural SMMEs.

Résumé :

Sustainably managing marine ecosystems has proved extremely difficult, with few success stories. Traditional approaches to managing ocean-borne activities, including the structure of the governance systems themselves, have had difficulty keeping pace with the dynamics of coupled human, ecological, and oceanographic systems. In essence, our governance systems for ocean resources and environments have had difficulty keeping pace with advances in ocean use and exploitation technologies.

In the United States today there are over twenty federal agencies and thirty-five coastal states and territories operating under hundreds of statutory authorities shaping coastal and ocean policy. For years, among marine ecologists and policy experts there has been consensus that a major overhaul in U.S. ocean governance is necessary. This dissertation broadly suggests the public trust doctrine--an ancient legal concept that is already incorporated in U.S. state coastal laws--could uniquely provide a critical legal foundation for a new era in U.S. federal ocean governance.

Though the public trust concept can be located in the legal systems of many countries, it robustly manifests in the United States, where it has historically protected the public's rights to fishing, navigation, and commerce in and over navigable waterways and tidal waters. In its most basic form, the doctrine obliges governments to manage common natural resources, the body of the trust, in the best interest of their citizens, the beneficiaries of the trust. Today the public trust doctrine is integral to the protection of coastal ecosystems and beach access in many states and has even made its way into state constitutions. It would be simple, and seemingly logical, to assume that the same fiduciary responsibility of states to protect public trust uses of their waters extends to all marine resources within the United States' 200-mile Exclusive Economic Zone (EEZ). However an artificial line has been drawn around state waters, and the legal authority and responsibility of the U.S. government to protect public trust resources in the vast space of its EEZ (the largest of any country on earth) have never been fully and expressly established. The second chapter in this dissertation outlines the development of states' public trust doctrines; discusses the expansion of U.S. sovereignty over its neighboring ocean waters during the twentieth century; analyzes possible avenues for expanding the doctrine to federal waters; and considers how a federal public trust doctrine could clarify some specific issues in U.S. oceans management. At the heart of this chapter's analysis lie three questions: (1) does a federal public trust doctrine exist; (2) if so, can it be rightfully extended to include the entirety of the U.S. ocean waters; and (3) could the doctrine provide the missing catalyst for federal agencies to manage the use of U.S. ocean resources in a coordinated, sustainable fashion?

The third chapter asks how the public trust doctrine could inform marine spatial planning in US waters. It argues that in the absence of a statutory mandate for agencies to collaborate in their management of ocean-borne activities, the public trust doctrine could provide a framework for restructuring the way the US federal government regulates ocean uses. The forth chapter examines the blowout of the Deepwater Horizon oil rig on April 20, 2010, and surmises that regulatory capture of the Minerals Management Service aided by a balkanized ocean governance regime in the pre-Deepwater Horizon era provided a potent source of systemic risk in the U.S. offshore oil and gas industry. It discusses the factors contributing to MMS' susceptibility to capture in the pre-Deepwater Horizon era, as well as examples of decisions it made that suggest dynamics of regulatory capture were at play. The chapter then explores the reform of offshore oil and gas regulation under BOERME and the National Ocean Council to understand the how these new governmental structures might be less susceptible to capture. Lastly, the chapter considers the added value of extending two alternative versions of a clear federal public trust mandate - a foundational US natural resources doctrine - to offshore oil and gas regulation and, more generally, to coastal and marine spatial planning under the National Ocean Council.

The final substantive chapter of this dissertation concerns the US Interagency Ocean Policy Task Force and reports the results of a case study analysis that I conducted to explore how and why the Task Force designed the National Ocean Policy and interagency governance structure, the National Ocean Council, like it did. I found that the recommendations of the Task Force drew heavily from previous studies of US federal ocean policy and the Committee on Ocean Policy, which lasted from 2004-2009. Additionally I sought to understand the Task Force within the context of other US interagency collaborative efforts and theories concerning collaborative governance. I found that the Task Force process was characterized by several characteristics that policy scholars have previously identified as important to promoting collaboration among agencies. I also found support for the theoretical proposition that often external and political factors have major impacts on the level of success attained by interagency efforts. Lastly, via interviews with Task Force staffers and content analysis of public comments submitted to the Task Force, I determined that - though not included in the National Ocean Policy - there remains interest in the principles of the public trust doctrine as underpinning for the policy, which seeks "[t]o achieve an America whose stewardship ensures that the ocean, our coasts, and the Great Lakes are healthy and resilient, safe and productive, and understood and treasured so as to promote the well-being, prosperity, and security of present and future generations."

Résumé :
University of Technology, Sydney. Faculty of Information Technology.
As e-Business has moved from a niche market to a decisive contributor for the success of most companies, some issues need to be solved in order to assist the continued success of e-Business. The challenge, to deploy fully autonomous business service agents which undertake transactions on behalf of their owners, often fails due to lack of trust in the agent and its decisions. Four aspects can overcome this challenge. Firstly, intelligent agents need to be equipped with self-adjusting reputation, trustworthiness and credibility evaluation mechanisms to assess the trustworthiness of potential counterparts prior to a business transaction. Secondly, such evaluation mechanisms must be transparent and easy to comprehend so agent owners develop trust in their agents’ decisions. Thirdly, the calculations of an agent must be highly customisable so that the agent owner can apply his personal experiences and security requirements to govern the decision making process of the intelligent agent. And finally, agents must communicate via standardised and open protocols in order to facilitate interaction between services deployed across different architectures and technologies. This thesis proposes the DEco Arch framework which integrates behavioural trust element relationships into various decision making processes found in e-Business ecosystems. We apply fuzzy-logic based soft computing techniques to increase user confidence and therefore enhance the adoption of the proposed assessment and review methodologies. A proof-of-concept implementation of the DEco Arch framework has been developed to showcase the proposed concepts in a case study and to conduct empirical experiments to evaluate the robustness and practicability of the proposed methodologies.

Résumé :
AbstractThe role data plays in enterprises is changing as the digital transformation in many sectors gains speed. New business opportunities through data-driven innovation emerge from data sharing in ecosystems. In ecosystems, the interest of the individual must be brought into alignment with the interest of the ecosystem. Trust between participants, data interoperability, and data sovereignty are key requirements which can be met by data spaces. Data spaces are a distributed data integration concept which is taken up by consortia aiming at supporting ecosystem. GAIA-X and IDS specify reference architectures for distributed data infrastructures and data spaces, respectively. While the benefits of data spaces for a fair data economy are recognized by business and policy makers, a deeper understanding is required about the design and evolution of data spaces. This chapter introduces fundamental concepts, identifies design tasks and options, and, thus, provides guidance for the establishment of data spaces.

Résumé :
AbstractPrivate and public organizations hoard troves of data yet remain unable to unlock its full business potential. Data exchange platforms powered by adapted technology and driven by data exchange strategies act as catalysts to develop data ecosystems and data spaces, accelerate data circulation, and liberate its value.Data spaces are powerful business, innovation, and societal enablers, whose growth and success rely on their ability to foster and develop trust.Data exchange platforms contribute a lot to building trust as they provide the required tools and automation to data acquirers, data providers, and data exchange services providers to operate at scale within secure and compliant environments.New and upcoming European regulatory frameworks also contribute to raising trust as they foster a harmonized data ecosystem across member states and define the rules of engagement between businesses, governments, and individuals engaged in data sharing and exchange.Additionally, data exchange environments must provide traceability at all levels of the data transactions, which is particularly needed in increasingly complex data ecosystems.Finally, in order to provide the flexibility required to answer the needs of complex, distributed, and heterogeneous environments, different models of data exchange governance are necessary.

Résumé :
Digitisation of governmental services has become a common approach to make governing more effective and efficient. The eGovernment services can be built on top of a variety of information systems and supplied to and between individuals and organisations on both national and international levels. This results in a complex organisational and sociotechnical ecosystem containing a vast amount of variables affecting the privacy and safety of citizens. Thus, achieving these better societies relies strongly on common trust between the citizens and governments. This calls for ‘governance of governance’, which can prove to be difficult to manage. Even in this challenging environment, it is crucial that ethical principles are applied to the highest possible degree. Yet, in current research, the citizens are often neglected. In order to develop a better society for all, we should objectively consider the ends and means of eGovernment. In this paper, we study the relation of the citizens and eGovernment systems from an ethical perspective in order to represent which ethical considerations should be made if one wishes to truly aim for a better society.

Résumé :
The Food Standards Agency (FSA) is responsible for public health in relation to food in England, Wales and Northern Ireland. It makes sure that people can trust that the food they buy and eat is safe and is what it says it is. As part of this responsibility, the FSA works to understand the continuing evolution of the food landscape to identify opportunities to improve standards of food safety and/or authenticity. As well as any new or magnified risks from which consumers should be protected. One area that has evolved rapidly is that of digital platforms in the food and drink industry. Consumers are increasingly purchasing food via third party intermediaries, known as ‘aggregators’, from a range of vendors. Digital platforms remain a relatively new concept, with many launching in the past decade. As such, there has been a knowledge gap in government about how these platforms work and how they impact the landscape in which they operate.

U.S. research security requires trust and collaboration between those conducting R&D and the federal government. Most R&D takes place in the private sector, outside of government authority and control, and researchers are wary of federal government or law enforcement involvement in their work. Despite these challenges, as adversaries work to extract science, technology, data and know-how from the United States, the U.S. government is pursuing an ambitious research security initiative. In order to secure the 78 percent of U.S. R&D funded outside the government, authors Melissa Flagg and Zachary Arnold propose a new, public-private research security clearinghouse, with leadership from academia, business, philanthropy, and government and a presence in the most active R&D hubs across the United States.

As sustainable community-driven scholarly infrastructure providers ORCID, Crossref and Datacite, guarantee data provenance and machine-readability. Persistent identifiers combined with open, standardized, and machine-readable metadata enable reliable and robust connections to be made between research outputs, organizations, individuals, and much more, as well as being beneficial to others who build services and tools on top of the open infrastructure we provide making content more discoverable. In this webinar we discuss: - Who we are - What we mean by Open Scholarly Infrastructure - How our organizations work together for the benefit of the scholarly community - How the Principles of Open Scholarly Infrastructure (POSI) help to build trust and accountability as well as ensure we are around for the long term. This is the first of the joint webinar series co-organized by Crossref, DataCite, and ORCID for the Open Science community in the APAC region. The webinar is presented in English and lasts 90 minutes including time for Q&A. This webinar took place on 27 June 2022 at 7am UTC/ 9am CEST / 5pm AEST.

Résumé :
This report maps the African landscape of Open Science – with a focus on Open Data as a sub-set of Open Science. Data to inform the landscape study were collected through a variety of methods, including surveys, desk research, engagement with a community of practice, networking with stakeholders, participation in conferences, case study presentations, and workshops hosted. Although the majority of African countries (35 of 54) demonstrates commitment to science through its investment in research and development (R&D), academies of science, ministries of science and technology, policies, recognition of research, and participation in the Science Granting Councils Initiative (SGCI), the following countries demonstrate the highest commitment and political willingness to invest in science: Botswana, Ethiopia, Kenya, Senegal, South Africa, Tanzania, and Uganda. In addition to existing policies in Science, Technology and Innovation (STI), the following countries have made progress towards Open Data policies: Botswana, Kenya, Madagascar, Mauritius, South Africa and Uganda. Only two African countries (Kenya and South Africa) at this stage contribute 0.8% of its GDP (Gross Domestic Product) to R&D (Research and Development), which is the closest to the AU’s (African Union’s) suggested 1%. Countries such as Lesotho and Madagascar ranked as 0%, while the R&D expenditure for 24 African countries is unknown. In addition to this, science globally has become fully dependent on stable ICT (Information and Communication Technologies) infrastructure, which includes connectivity/bandwidth, high performance computing facilities and data services. This is especially applicable since countries globally are finding themselves in the midst of the 4th Industrial Revolution (4IR), which is not only “about” data, but which “is” data. According to an article1 by Alan Marcus (2015) (Senior Director, Head of Information Technology and Telecommunications Industries, World Economic Forum), “At its core, data represents a post-industrial opportunity. Its uses have unprecedented complexity, velocity and global reach. As digital communications become ubiquitous, data will rule in a world where nearly everyone and everything is connected in real time. That will require a highly reliable, secure and available infrastructure at its core, and innovation at the edge.” Every industry is affected as part of this revolution – also science. An important component of the digital transformation is “trust” – people must be able to trust that governments and all other industries (including the science sector), adequately handle and protect their data. This requires accountability on a global level, and digital industries must embrace the change and go for a higher standard of protection. “This will reassure consumers and citizens, benefitting the whole digital economy”, says Marcus. A stable and secure information and communication technologies (ICT) infrastructure – currently provided by the National Research and Education Networks (NRENs) – is key to advance collaboration in science. The AfricaConnect2 project (AfricaConnect (2012–2014) and AfricaConnect2 (2016–2018)) through establishing connectivity between National Research and Education Networks (NRENs), is planning to roll out AfricaConnect3 by the end of 2019. The concern however is that selected African governments (with the exception of a few countries such as South Africa, Mozambique, Ethiopia and others) have low awareness of the impact the Internet has today on all societal levels, how much ICT (and the 4th Industrial Revolution) have affected research, and the added value an NREN can bring to higher education and research in addressing the respective needs, which is far more complex than simply providing connectivity. Apart from more commitment and investment in R&D, African governments – to become and remain part of the 4th Industrial Revolution – have no option other than to acknowledge and commit to the role NRENs play in advancing science towards addressing the SDG (Sustainable Development Goals). For successful collaboration and direction, it is fundamental that policies within one country are aligned with one another. Alignment on continental level is crucial for the future Pan-African African Open Science Platform to be successful. Both the HIPSSA ((Harmonization of ICT Policies in Sub-Saharan Africa)3 project and WATRA (the West Africa Telecommunications Regulators Assembly)4, have made progress towards the regulation of the telecom sector, and in particular of bottlenecks which curb the development of competition among ISPs. A study under HIPSSA identified potential bottlenecks in access at an affordable price to the international capacity of submarine cables and suggested means and tools used by regulators to remedy them. Work on the recommended measures and making them operational continues in collaboration with WATRA. In addition to sufficient bandwidth and connectivity, high-performance computing facilities and services in support of data sharing are also required. The South African National Integrated Cyberinfrastructure System5 (NICIS) has made great progress in planning and setting up a cyberinfrastructure ecosystem in support of collaborative science and data sharing. The regional Southern African Development Community6 (SADC) Cyber-infrastructure Framework provides a valuable roadmap towards high-speed Internet, developing human capacity and skills in ICT technologies, high- performance computing and more. The following countries have been identified as having high-performance computing facilities, some as a result of the Square Kilometre Array7 (SKA) partnership: Botswana, Ghana, Kenya, Madagascar, Mozambique, Mauritius, Namibia, South Africa, Tunisia, and Zambia. More and more NRENs – especially the Level 6 NRENs 8 (Algeria, Egypt, Kenya, South Africa, and recently Zambia) – are exploring offering additional services; also in support of data sharing and transfer. The following NRENs already allow for running data-intensive applications and sharing of high-end computing assets, bio-modelling and computation on high-performance/ supercomputers: KENET (Kenya), TENET (South Africa), RENU (Uganda), ZAMREN (Zambia), EUN (Egypt) and ARN (Algeria). Fifteen higher education training institutions from eight African countries (Botswana, Benin, Kenya, Nigeria, Rwanda, South Africa, Sudan, and Tanzania) have been identified as offering formal courses on data science. In addition to formal degrees, a number of international short courses have been developed and free international online courses are also available as an option to build capacity and integrate as part of curricula. The small number of higher education or research intensive institutions offering data science is however insufficient, and there is a desperate need for more training in data science. The CODATA-RDA Schools of Research Data Science aim at addressing the continental need for foundational data skills across all disciplines, along with training conducted by The Carpentries 9 programme (specifically Data Carpentry 10 ). Thus far, CODATA-RDA schools in collaboration with AOSP, integrating content from Data Carpentry, were presented in Rwanda (in 2018), and during17-29 June 2019, in Ethiopia. Awareness regarding Open Science (including Open Data) is evident through the 12 Open Science-related Open Access/Open Data/Open Science declarations and agreements endorsed or signed by African governments; 200 Open Access journals from Africa registered on the Directory of Open Access Journals (DOAJ); 174 Open Access institutional research repositories registered on openDOAR (Directory of Open Access Repositories); 33 Open Access/Open Science policies registered on ROARMAP (Registry of Open Access Repository Mandates and Policies); 24 data repositories registered with the Registry of Data Repositories (re3data.org) (although the pilot project identified 66 research data repositories); and one data repository assigned the CoreTrustSeal. Although this is a start, far more needs to be done to align African data curation and research practices with global standards. Funding to conduct research remains a challenge. African researchers mostly fund their own research, and there are little incentives for them to make their research and accompanying data sets openly accessible. Funding and peer recognition, along with an enabling research environment conducive for research, are regarded as major incentives. The landscape report concludes with a number of concerns towards sharing research data openly, as well as challenges in terms of Open Data policy, ICT infrastructure supportive of data sharing, capacity building, lack of skills, and the need for incentives. Although great progress has been made in terms of Open Science and Open Data practices, more awareness needs to be created and further advocacy efforts are required for buy-in from African governments. A federated African Open Science Platform (AOSP) will not only encourage more collaboration among researchers in addressing the SDGs, but it will also benefit the many stakeholders identified as part of the pilot phase. The time is now, for governments in Africa, to acknowledge the important role of science in general, but specifically Open Science and Open Data, through developing and aligning the relevant policies, investing in an ICT infrastructure conducive for data sharing through committing funding to making NRENs financially sustainable, incentivising open research practices by scientists, and creating opportunities for more scientists and stakeholders across all disciplines to be trained in data management.
