Testo completoAbstract (sommario):
It is an emerging phenomenon that the leading multinational companies are studying how to use the engagement experiences of customers and communities as the foundation of value co-creation. To achieve this, the business leaders have increasingly adopted an ecological organizational form, namely business ecosystem. Google, Amazon and Microsoft are the real world examples and pioneers in this field. However, in the academic research, it is addressed by a number of researchers that there is significant lack of empirical studies that examines the emergence and formation of business ecosystem, especially in ICT industry. In essence, this study takes Cloud as the context to develop concepts on the emergence of business ecosystem and examine the manifestation of such evolution in the emerging business field.
Through extensive literature reviews and empirical interviews, the current study developed answers to the research question, “How do new business ecosystems emerge, in the context of Cloud computing?” at qualitative level. In general, it is considered in the study that business ecosystem is a type of more advanced business form emerged recently. It has the characteristics as follow: provision of value, integration with external partners, requiring multiple participants, shifting from individual to collaborative thinking, interdependence of the participants, value co-creation, co-petition, open innovation and shared fate of success or failure.
From a macro level viewpoint, the emergence of business ecosystem is the result of the continuous evolution of business forms, from linear type towards a more complex networked type. At a micro level, for an ecosystem to emerge in a given industry, it involves strategic design and appropriate execution. Furthermore, a set of critical elements need to be in the right place for a business ecosystem to emerge, which including: prerequisite conditions for ecosystem to emerge, external environmental and resource, shared vision, leadership of the ecosystem, common platform, mechanisms of the ecosystem, ecosystem healthiness, and IT infrastructure.
The study further suggests that the emergence of business ecosystem as a new business form is not out of luck or probability. It is a natural path that under governance of the evolution forces existing in the social-economic contexts, just as the evolution of all the living creatures in the natural environment. For this broader perspective, the emergence of ecosystem is inevitable due to the social-economic and technological driving forces.

Testo completoAbstract (sommario):
Ecosystem-based management (EBM) is increasingly seen as the new paradigm for managing the use of marine resources and ecosystems. Although EBM has been defined in theory, its implementation has faced challenges worldwide. This research aims to examine two approaches to contribute to the operationzalization of EBM by incorporating stakeholder values in the decision-making process, and by better representing ecosystem dynamics in ecosystem models. First, I illustrate a decision-making framework for EBM rooted in structured decision-making (SDM), a well-known systematic approach for planning and stakeholder-consultation processes. SDM helps to identify the values of the constituents and define objectives and indicators that are consistent with those values. I demonstrate how SDM can enable managers to evaluate the performance of management alternatives using indicators specifically chosen to reflect values. This can help managers make more systematic, transparent and informed decisions with respect to the use of marine resources. As a case study, I apply SDM to the marine planning process on the west coast of Vancouver Island (WCVI). Second, as ecosystem models play an important role in EBM, I strive to improve the representation of marine ecosystems using ecosystem models in Ecopath with Ecosim (EwE). I focus on incorporating mediating effects and species reintroductions, both common situations that can strongly influence ecosystem dynamics. These considerations are essential when applying holistic approaches to management but they are not generally included in EwE. I use EwE to model the reintroduction of sea otters (Enhydra lutris) and the mediating effects provided by kelp forests in nearshore ecosystems of the WCVI. Because EwE does not have the functionality to represent reintroductions, I created two scenarios to work around the assumptions of Ecospace on the initial state of the ecosystem. In addition, I demonstrate how mediating effects can be represented using the ‘mediation’ function in Ecosim. These methods and results can contribute to advance EBM on the WCVI and offer insights to other marine planning processes. Both strengths and limitations of this work are presented and analyzed.

Testo completoAbstract (sommario):
Purpose - The purpose of this thesis is to advance the understanding of risk exposure and management for different roles in business ecosystems. The following research questions have been derived to fulfill this purpose: RQ1: Which risks are different business ecosystem roles exposed to, and in what way? RQ2: How can business ecosystem actors mitigate risks? Method – A single case study has been conducted on a business ecosystem surrounding the development of autonomous cars in the EU. An abductive and qualitative approach has been applied, which allowed the combination of existing literature and new empirical findings as to the foundation for building new theory. Data was collected through 21 semi-structured interviews and analyzed through comparison between codes on risks, roles, and risk mitigation strategies. Findings – The already existing literature on business ecosystem risks was confirmed and nuanced. On top of this, two new risks were found, disintermediation risk (the risk of being fully or partially excluded from the ecosystem) and accountability risk (the risk of being responsible for other business ecosystem actors output to a third party). The findings also declare that risks vary between actors, but also due to other factors such as investment in the ecosystem and an actor's relative size to other actors. Finally, suggested risk response strategies for each risk were derived. Theoretical implications - We have contributed to the literature on risks within business ecosystems by adding two new risks: disintermediation risk and accountability risk. We have also contributed to the overall literature on business ecosystems by combining the two sub-streams risks in business ecosystems and roles in business ecosystems. In addition to the theoretical implications for the business ecosystem literature, we have contributed to the risk management literature by applying it in the new context of business ecosystemsto extend the applicability of the risk management literature. Practical implications - Our findings shed light on how risks are distributed between different roles and can therefore provide guidance in this issue. The current study also contributes to the understanding of how risks vary with respect to other factors than roles, which could be valuable knowledge for managers. Finally, practical guidance on how risks can be mitigated is presented which is valuable for any actor in a Business ecosystem.

Testo completoAbstract (sommario):
This thesis assessed the current prospect for implementing an ecosystem-based management for fisheries (EBFM) in the Bay of Bengal Large Marine Ecosystem from national and regional level perspectives. A central result of the study is that the governance concept had been defined and used imprecisely in the literature. The way the different elements constitute EBFM revealed that both Bay of Bengal LME countries and existing regional fisheries organisations are unlikely to satisfy all the elements on the EBM checklist. The study also observes that the Bay of Bengal countries do not share a common understanding of EBFM.

Testo completoAbstract (sommario):
Human wellbeing in cities, often associated to availability of engineered structures, is increasingly linked to the conservation of ecosystems. This is the case of the urban water sector where the focus is shifting from adequate infrastructural arrangements to the key role of ecosystem services, thus offering a unique opportunity to achieve sustainability transitions. The urban water sector entails significant complexities and uncertainties, which no longer can be addressed effectively with traditional approaches. A new paradigm of “adaptation and integration”, emerging as a collective effort of stakeholders that engage themselves in a process of social learning, is needed. However, real-life implementation is arduous: it requires linking diverse stakeholders and knowledge systems, across management levels and institutional boundaries. Three innovative concepts can help face this challenge, namely, ecosystem services, boundary work and learning organizations. Ecosystem services provide a holistic approach for framing socio-ecological issues and for integrating different biophysical and socio-economic data. Boundary work, i.e. the effort put in place to facilitate transfer of knowledge into action, informs active management of the tension at the interface between stakeholders that have differing views on what constitutes relevant knowledge. A learning organization is one that is skilled at creating and acquiring knowledge and modifying its behavior to reflect new insights. In this study, these three concepts are jointly explored to build operative approaches to support the implementation of adaptive management. To this end, the work is driven by four specific objectives presented hereafter. The first objective is to frame the urban water sector from an ecosystem services perspective, synthesizing the most relevant aspects related to the exchange of water between watershed and city, and within the city. The proposed framework highlights the role of the urban water sector in (i) linking ecosystem service production and benefit areas, (ii) bridging spatial scales ranging from the watershed to the household level and (iii) adopting ecosystem service-based responses to drivers of water vulnerability. The second objective is to explore practices of boundary work in adaptive watershed management. Thus, an empirical investigation of how boundary work can facilitate knowledge co-generation and cooperative application in a case study of adaptive management in the Fuhrberg watershed (Germany) is conducted. The results suggest that scientific insights have been crucial for "enlightenment", "decision-support", and in "negotiations" between a water utility and stakeholders in Fuhrberg watershed management. The successful implementation of adaptive watershed management is attributed to boundary work deployed by the water utility and ultimately to its high institutional capacity. This study, which is one of the first empirical assessments of boundary work in practice, presents many promising approaches for initiating boundary work in the case of water utilities. Yet, more comparative research is required to understand the influence of contextual differences on appropriate methods and potential outcomes of boundary work. The third objective is to build and test an approach for designing and assessing impact of watershed investments, aiming to implement adaptive management. The proposed approach is structured to facilitate negotiations among stakeholders. Its strategic component includes setting the agenda, defining investment scenarios, and assessing the performance of watershed investments. Its technical component consists of tailoring spatially explicit ecosystem service models, generating future land use scenarios, and modeling impacts on ecosystem services. The approach is applied to a case study in a data-scarce context: Toker Watershed (Eritrea), considering soil erosion -related challenges. It produced spatially explicit data, which has been aggregated to assess quantitatively the performance of watershed investments, in terms of changes in selected ecosystem services, thus answering key management and planning questions. By addressing stakeholders’ concerns of credibility, saliency, and legitimacy, the approach is expected to facilitate the negotiation of objectives, definition of scenarios, and assessment of watershed investments. The fourth objective is to explore water utilities as learning organization implementing adaptive watershed management. A conceptual framework for evaluating the institutional capacity of water utilities is used to characterize the water utilities in Hanover and Asmara. In particular, the institutional capacity of the “Hannover Water Utility” and “Asmara Water Supply Department” is investigated based on the available information from documents, literature and the previous results, and an interview with a key informant. The results show that the institutional capacity of Hanover Water Utility can be classified as Level 5 – “Progressive water utility” and Asmara Water Supply Department can be classified as Level 2 – “Basic water utility”. An empirical pathway to test the results, by involving senior managers and informed scientists from both case studies, is proposed. In any case, the preliminary results highlight the attributes that determine the capacity of water utilities to become a central actor in the in the implementation of an adaptive watershed management. This research, by jointly exploring the innovative concepts of ecosystem services, boundary work and learning organizations, builds operative approaches that can support the implementation of adaptive watershed management. Further work is needed to address some of the complexities and uncertainties underlying the proposed approaches, including data resolution, model calibration, and above all participation of real-life stakeholders

Digital payment has proven to be an effective tool to narrow the gaps in financial inclusion. In this area, China has outperformed most developed countries, with Alipay taking the leading role. After achieving critical mass in the domestic market through building a comprehensive ecosystem, Alipay, like many other Chinese tech giants, is also considering expanding its reach into the global market. Among emerging countries, Brazil stands out as being an ideal target for many reasons. Currently, large portions of Brazilian population and a significant number of small businesses are underserved by a concentrated and highly profitable banking system. Additionally, the domestic Brazilian FinTech market is still nascent and fragmented. By building up an Alipay-like payment ecosystem in Brazil, Alipay could create synergy with the local financial system and enable players and users to capture more value from it. This study analyzes the dynamics and structure of Alipay's ecosystem, decodes the key drivers of its success in China and reviews some of its first experiments in the global market. This study also assesses the FinTech market in Brazil by evaluating opportunities Alipay could capture, and risks and challenges it has to take into consideration. This study also includes an analysis of Alipay's Artificial Intelligence development domestically and internationally. Finally, this study develops strategic suggestions for Alipay to enter the Brazilian market.

This study examines opportunities for coordinated road
management for purposes of ecosystem management. The
coordination efforts in Greater Yellowstone provide a case
study illustrating these opportunities.
The study first reviews current literature about ecosystems, ecosystem management goals, benefits and the application of the concept to Greater Yellowstone. Issues of forest road management are also examined.
The study then turns to a critique of current road
management efforts in six National Forests of northwest
Wyoming, southwest Montana and eastern Idaho; which are
considered part of the Greater Yellowstone Ecosystem.
Comparisons of road management planning and policy will be
made primarily through examination of forest plans and
engineering policies, and through personal communication
with forest highway engineers and transportation planners.
Recommendations for improving coordination of forest road
management follow the critique.

Testo completoAbstract (sommario):
A principal purpose of this thesis is to present an economic evaluation of ecosystems. The concept of ecosystem health is adopted to ascertain the status of ecosystems. Ecosystem health is considered in part an economic concept and defined as a function of utility through the ecosystem services that satisfy various needs, subject to preserving the integrity of the adaptive cycle. In order to quantify the utility supplied by ecosystem services the novel utility index Ecosystem Outcome Protection Year (ECOPY) is developed. By forming this index, an evaluation can be performed using cost utility analysis, which avoids monetizing these benefits. An attempt is made to ascertain an appropriate approach for ecosystem management. It is reasoned that expert intuition can determine some kind of macro-regularities in ecosystems despite their complex dynamics. Hence, these inferences could be used for ecosystem management. Adaptive co-management is introduced as a means to bring about the collaboration of experts as resource co-managers. The concept of informed intuition is developed to bring about a systematic approach to learning and evaluation where the mental models of experts are transcribed using fuzzy cognitive mapping. However, it is argued that ecosystems as complex adaptive systems are non-ergodic and full of surprises. Accordingly, abduction, the logic of creative conjecture is systematically developed, for the purposes of maintaining mental model flexibility. This systematic application of abduction with an informed intuition forms the proposed abductive process of research, which is grounded in Shacklean potential surprise, a non-probabilistic function. To demonstrate this novel research process, a post-classical economic evaluation of Te Waihora lake ecosystem is undertaken, which employs the ECOPY index and potential surprise method. This empirical case study reveals various cost-effective management actions for improving lake health, which went beyond the intuitions of resource co-managers. This indicated the potential of the approach, which is considered a significant contribution for the methodological development of ecosystem management.

Fire has been an important influence on the structure and health of the North American grasslands for hundreds of years. In Jersey County Illinois, two natural loess hill prairies were studied to compare the effectiveness of varying management regimes. The purpose was to determine how a burn vs. a nonburn management regime enhances or hinders the establishment of the prairie grasses and forbs in a tallgrass hill prairie ecosystem. The variables studied included: the vegetational abundance, the frequency, and the biomass of the species that were present. In addition the soil's organic matter content and pH were measured. Overall, the Fire Road Prairie, or the unburned prairie, proved to be the community that was deteriorating and becoming unproductive. Whereas, the Osage Prairie contained a balance of grasses and forbs that were representative of a healthy and thriving community. The data supported the existing theory that a burn management plan does help the overall stability and productivity of a tallgrass ecosystem.Department of Natural Resources and Environmental Management

Following the Arab Spring and the Tunisian uprising, many saw Tunisia as a country leading change. A strong willingness to act came along with this shift. Mostly, all the stakeholders in the Tunisian society worked towards tackling the deeply rooted matters from which the Tunisian revolution stems, including the issue of the regional economic disparity. In this context, numerous people perceived entrepreneurship as a substantial solution for the latter matter, leading to a great vibrancy in the Tunisian entrepreneurial scene. It is therefore paramount to reassess, as a first step, the actual entrepreneurial ecosystem within the Tunisian context and apprehend how its key elements were shaped in order to optimize later on its economic impact. In our study, we will begin by highlighting the relationship between entrepreneurship and economic development, especially on the regional level. This understanding stands as the rationale behind the goal of this paper. Then, we will provide a state-of-the-art analysis of the Tunisian entrepreneurial ecosystem through a framework that envisions taking into account all the stakeholders and the influencers of the Tunisian environment. We will finally, put forward the current shortcomings to be dealt with, in order to ultimately offer options we can apply to enhance and develop the Tunisian entrepreneurial scene.

Testo completoAbstract (sommario):
The thesis tried to understand how renowned open data initiatives work, and give an attempt to investigate the relations between actors in an open data ecosystem. This was with ambitions to understand managerial approaches open data initiatives have adopted, to develop an understanding of actions and relations; where, how and whom initiatives support and facilitate. This is understandably of concern as not all open data initiatives reach a point where they have managed to bring about valuable impacts. The underlying assumption here is that it is difficult to visualise where and how open data can be beneficial, as such governmental open data initiatives remain stagnant with a limited understanding of strategies to adopt. The method of approach has been semi-structured interviews with international governmental open data officials. The findings suggest that open data management remarkably consist of approaches that are user-orientated and aim for governmental data management capacities. These two measures combined can instigate greater interaction between data users and publishers, which subsequently uncovers degrees of uncertainty and aids in building an open and digital system. Furthermore, the initiatives focus heavily on building awareness and consequently demonstrating value. It is crucial for open data initiatives to build momentum in activities through informing, teaching and engaging data users and publishers. Their end target is to demonstrate value for both sharing and using data. Certain risk is still inherent in opening up data, with that it is recommended to start small and safe - to build on small projects, observe outcomes, and then take directions.open data initiative; ecosystem; complex; uncertainty; stagnant; change management; simple order-generating rule

Environmental degradation is accelerating worldwide, yet environmental conservation remains limited by funding. Tackling this limitation requires not only absolute increases in funding, but improved prioritisation of actions. On a global scale island ecosystems are of high priority, with invasive species one of their most significant threats. In this thesis I investigate prioritisation of invasive grazing species control, incorporating ecological, economic, and social concerns, on the island of Bonaire, Caribbean Netherlands. To enable the trade-off of potential grazer control options for their ecological impacts I modelled the relationship between of grazer density and vegetation, and watershed vegetation and the coral reef. I found negative relationships for goat and pig grazing with grass presence, and for donkey grazing with ground cover. Coral cover below 10m showed a positive relationship to ground cover, and, surprisingly, a negative relationship to tree biomass. Because conservation action is most likely to be sustainable when connected to funding, I conducted choice experiments with SCUBA divers, which estimated a positive willingness to pay for reef health improvements achieved using terrestrial grazer control. Through communication with local policy makers and practitioners I identified three options for grazer control, eradication, population reduction, or fencing, and estimated costs and social acceptability for each option. Though the ecological models predicted eradication to have the highest impacts on the terrestrial and marine ecosystem, lower costs and higher social acceptability identified fencing as the most suitable option for grazer control on Bonaire in the short term, with the potential to be funded through a fee on SCUBA divers. Through linking ecological, economic, and social considerations within a real world conservation context I illustrate the importance of looking beyond only ecological improvements when prioritising conservation action. This research is directly applicable to policy and practise on Bonaire.

Testo completoAbstract (sommario):
Urban green spaces are put under high pressure due to increasing population density in cities. This problem will potentially accelerate where the densification in the cities continues. Consequently, this sets high requirements on the management, if the green spaces are to generate the benefits and values that are associated with greens spaces as urban parks. One way to increase these benefits and values could be to incorporate ecosystem services and indicators for ecosystem services in a multi-stakeholder management system. Is it possible that ecosystem service indicators could facilitate collaboration between stakeholders and thus improve the value of urban green space? This master thesis aimed to identify ecosystem service indicators for a green space and incorporate them in a multi-stakeholder management system. The study was made to clarify if indicators can facilitate collaboration between stakeholders and thus improve the management of an urban green space. In order to achieve that, the first step was to let the stakeholders express what they desired the green space to generate in terms of benefits and values. These expressed benefits and values were formulated into target variables which were linked with the ecosystem services that the green space was assessed to generate if the target variables are achieved. A literature study was conducted to identify applicable indicators for the chosen ecosystem services. These indicators were quantified and incorporated into an already existing management system. This management system performed as a framework and a fundament which was further developed to incorporate more functions as indicators and ecosystem services. The thesis resulted in two identified indicators for ten ecosystem services and the development of a multi-stakeholder management system. Identified indicators were birds and compliant seating. Birds were identified as an indicator because they indicated many of the same ecosystem services as the ones that are generated in the green space. These ecosystem services are linked with the benefits and values that are associated with the target variables. In addition, the birds were chosen because they were possible to quantify. Compliant seating was the second indicator, and it has the potential to function as a control indicator as it can be seen as a manifestation of the cultural ecosystem services generated at the green space. A multi-stakeholder management system was developed with the incorporation of indicators for ecosystem services. The developed management system aimed to facilitate the collaboration between stakeholders with the use of ecosystem service indicators. Taken together, the findings suggest a role for ecosystem service indicators in multi-stakeholder management plans to improve the value of green spaces.Grönytor i städer är satt under hög press på grund av ökande befolkningstäthet vilket leder till att fler människor behöver dela på samma mängd urban grönyta. Detta fenomen ökar kraven på förvaltningen av grönytor då de behöver generera fler nyttigheter och mera värde. Ett sätt att öka dessa värden skulle kunna vara att använda sig av indikatorer för ekosystemtjänster inom ett förvaltningssystem där flera förvaltare verkar. Är det möjligt att indikatorer för ekosystemtjänster kan underlätta samarbetet mellan olika förvaltare och därigenom öka värdet av en grönyta? Den här masteruppsatsen hade målet att identifiera indikatorer för ekosystemtjänster genererade av en grönyta och sedan inkorporera dem i en förvaltningsmetod som ökar samverkan mellan förvaltare. Studien syftade till att tydliggöra om användandet av ekosystemtjänstindikatorer kan underlätta samarbetet av mellan olika förvaltare för att förbättra förvaltningen av en grönyta. Det första steget för att åstadkomma detta var att låta förvaltarna uttrycka vilka värden och nyttigheter de vill att grönytan skulle skapa. Dessa värden och nyttigheter formulerades som målvariabler vilka länkades till de ekosystemtjänster som grönytan bedömdes generera. Genom en litteraturstudie identifierades indikatorer som kunde indikera de ekosystemtjänster som genererades vid grönytan. Indikatorerna kvantifierades och inkorporerades in i ett redan existerande förvaltningssystem. Studien resulterade i två identifierade indikatorer och i utvecklandet av ett förvaltningssystem som underlättar samverkan genom användandet av indikatorer. Fåglar identifierade som en indikator på grund av att fåglar indikerade samma ekosystemtjänster som genereras på grönytan. Fåglar valdes också för att det var möjligt att kvantifiera fåglarna vid grönytan. Villkorlig sittplats var den andra indikatorn och den har möjligheten att fungera som en kontrollindikator eftersom den kan beskrivas som en manifestation av de ekosystemtjänster som genereras på grönytan. Sedan så utvecklas även ett förvaltningssystem där indikatorerna inkorporerades. Förvaltningssystemet hade målet att underlätta samverkan mellan de olika förvaltarna med hjälp av indikatorerna. Sammanfattningsvis så bedöms det att indikatorer för ekosystemtjänster har potentialen att användas i ett förvaltningssystem och därigenom kunna bidra till att öka värdet av grönytan.

Testo completoAbstract (sommario):
Coastal ecosystems are crucial to sustain productive and functioning seascapes because they provide numerous ecosystem services. However, they are under threat and overburdened by multiple anthropogenic land-based and marine-based threats. Managing these threats is challenging because governance of the activities from which threats derive is often segregated and atomistic. Therefore, it is important to assess how management performs across the seascape to ensure adequate protection for coastal ecosystems from multiple threats. Assessing management performance, defined as the ability to meet management objectives, can help managers identify under-performing sites that may need extra management attention (e.g., enforcement, capacity building, or monitoring). Further, it can infer the recovery potential of targeted species or habitats to inform on biologically realistic performance targets. We use the systematic conservation planning framework to explore targeted questions about conservation planning, to identify management gaps and inform on global and regional management decisions.This work begins by asking a series of questions about why management is failing to protect one of the most neglected coastal ecosystems, seagrass. The underlying reason is that seagrass ecosystems are not recognised in legislation or policy and therefore their status and trends are not evaluated against any performance targets. This work has formed part of a global movement to improve the management of seagrass ecosystems, together with authorities charged with global governance of the environment. I then consider how performance targets take into account the social and environmental drivers of fish biomass and assess how this shapes fish recovery. I use this information to inform on management decisions in two case-studies: the northern region of New South Wales, Australia, and in two regional Marine Protected Areas (MPAs) in southern Raja Ampat, Indonesia. In the NSW case study, I identify coastal areas that are at greatest risk to cumulative threats and suggest how management performance could be improved to protect temperate reef fish. In the Indonesian case-study, I suggest that to effectively evaluate MPA performance, it is critical to link historical threats and environmental conditions with coral reef fish outcomes. I then return to seagrass ecosystems as a case study to refine performance targets for monitoring to enable better detection of ecosystem trends. This work, carried out in southern Moreton Bay, Queensland, indicated that metabolomics could allow ecosystem trends to be identified more consistently and with greater accuracy than current methods. In my final chapter, I discuss the implications of these findings and make recommendations for key areas of further research. Each chapter of this thesis, although broad in design, has the same application to inform managers to make better decisions to protect coastal ecosystems. All chapters have an applied outcome and have utilised collaborators to make the information accessible to conservation managers.Thesis (PhD Doctorate)

Includes bibliographical references.
This thesis is concerned with the commercial applications of MEMS (Micro-Electro-Mechanical Systems) manufacturing processes to advanced energy technologies. This field of engineering has come to be known as Power MEMS. Four such technologies are singled-out for detailed consideration, based on the efforts that have gone into demonstrating the benefits which MEMS has to offer them. The first are micro engines or turbines which generate of order 10-100 Watts of power by driving an electric generator, as exemplified by the famous MIT microturbine. The second are micro fuel cells, electrochemical devices which air oxidize chemical fuels, particularly the direct methanol fuel cell which operates at modest temperatures and hence is suitable for use in portable electronics. The third are solid-state devices which convert heat into electricity via either the Seeback (thermocouple) or photovoltaic effects, or else via thermionic emission. Finally, we consider devices which scavenge vibrational or electromagnetic energy from their environment, and are an attractive means of powering remote autonomous sensors or medical implants such as pacemakers.
(cont.) Following a survey of recent commercial activity in these technologies, we consider the markets they may serve, the economics of their MEMS-based production, and possible business models for their commercialization. Detailed case studies are presented of two recent startups, one of which is developing a heat-to-electricity conversion system based on the photovoltaic effect, and the other of which is studying a novel MEMS device which would use springs made out of carbon nanotubes to store energy. The conclusion is that the time is ripe for a power MEMS technology roadmap which can inspire energy technology companies to work together towards an industrial ecosystem like that now seen in the semiconductor industry. Specifically, we propose that by using MEMS as a unifying technology, it will become possible to easily buy, sell and trade knowledge, personnel, components and foundry services, facilitating experimentation with new products and business models and greatly accelerating the development of power MEMS itself. This may in turn lead to solutions to some of the pressing energy and environmental problems which society now faces.

Testo completoAbstract (sommario):
The growing costs of the healthcare sector are a severe problem that needs to be resolved in order to provide a good quality care for the ones needing it. New and innovative solutions can, for example, help to lower the costs without endangering the patient safety and provide new operation models which enable the development of beneficial cooperation between healthcare actors. Innovations can also enable the care of patients that could not be treated with existing solutions. Living labs are innovation platforms that aim to create innovative and user-centred solutions by supporting development work and enabling real-environment testing and cooperative processes. Living labs can also help to increase the amount of innovations. This thesis examines the living lab methodology and its value creation for the ecosystem using a living lab acting on a health and wellbeing field, the OuluHealth Labs, as a case example. The thesis is made as a part of the Business Ecosystems and Platforms project at the Industrial Engineering and Management research group in the University of Oulu. The aim is to find internal factors that affect the viability of the living lab and identify how the living lab creates value to the ecosystem actors. Study is done as a qualitative case study using the triangulation approach for the empirical data collection and analysis. Living labs are complex unities that have several influential factors. In case of the OuluHealth Labs, several factors affect its viability, namely, the bureaucracy, planned lifetime, the formation of communication barriers, scale, management, technical infrastructure, information control, ecosystem strategy, effective cooperation, the involvement of the public sector, trust creation, ownership, responding to the market needs, and the relation to the real environment. The living lab also needs to create value to the ecosystem around it. The OuluHealth Labs aims to create value via collaborative processes, offered spaces, expert services, and promotion of networking. The collaborative processes and the expert services can, for example, ease the bureaucratic processes linked to the health and wellbeing field solutions by offering standardised processes for the application and license processes. The received results can provide guidelines for a healthcare related the living lab in the design phase. However, the relation of the case example to the public sector and the special characteristics of the healthcare sector should be taken into consideration when assessing the suitability of the results in general useTerveydenhuoltosektorin kasvavat kustannukset ovat ongelma, joka tulee ratkaista jotta laadukasta hoitoa kyetään jatkossakin tarjoamaan sitä tarvitseville. Uudenlaisten innovatiivisten ratkaisujen avulla on mahdollista saada kustannukset laskuun potilasturvallisuutta vaarantamatta ja kehittää uudenlaisia toimintamalleja jotka mahdollistavat hyödyllisen ja tehostavan yhteistyötoiminnan terveydenhuollon toimijoiden välillä. Innovaatioiden avulla voidaan myös löytää hoitomenetelmiä joiden avulla voidaan hoitaa potilaita, joille aiemmin ei ollut hoitoa tarjolla. Living labit ovat innovaatioalustoja, jotka pyrkivät luomaan innovatiivisia ja käyttäjäkeskeisiä ratkaisuja tukemalla kehitystyötä ja yhteistyöprosesseja sekä mahdollistamalla testauksen oikeassa käyttöympäristössä. Living lab menetelmällä voidaan myös lisätä syntyneiden innovaatioiden määrää. Tässä työssä tarkastellaan living lab menetelmää ja sen arvonluontia ekosysteemille käyttäen esimerkkinä terveyden- ja hyvinvointialaan liittyvää OuluHealth Labsia. Työ on tehty osana Business Ecosystems and Platforms for Innovations projektia Oulun yliopiston tuotantotalouden tutkimusryhmässä. Työn tavoitteena on tunnistaa sisäiset tekijät, jotka vaikuttavat living labin elinkelpoisuuteen ja löytää mekanismit, joilla OuluHealth Labs luo arvoa ympärillään olevalle ekosysteemille. Työ on tehty kvalitatiivisena tapaustutkimuksena käyttäen menetelmä- ja teoriatriangulaatiota. Living labit ovat monimutkaisia kokonaisuuksia joissa on useita vaikuttavia tekijöitä mukana. OuluHealth Labsin tapauksessa elinkelpoisuuteen vaikuttaviksi tekijöiksi tunnistettiin byrokratia, suunniteltu elinikä, kommunikaatio esteiden muodostuminen, laajuus, johtaminen, tekninen infrastruktuuri, informaatiovirtojen kontrolli, ekosysteemin strategia, tehokas yhteistyö, julkisen sektorin osallistuminen, luottamuksen muodostaminen, omistus, markkinoiden kysyntään vastaaminen ja yhteys todelliseen ympäristöön. Kyetäkseen toimimaan living labin tulee luoda arvoa ympärillään olevalle ekosysteemille. OuluHealth Labs luo arvoa yhteistyöprosessien, tilapalveluiden, asiantuntijapalveluiden ja verkostoitumisen edistämisen kautta. Yhteistyöprosessit ja asiantuntijapalvelut luovat arvoa esimerkiksi pyrkimällä vähentämään aikaa, joka asiakasyrityksillä kuluu terveydenhuoltoalalle ominaiseen byrokratiaan. Tämä voi tapahtua muun muassa kehittämällä valmiita prosesseja lupa- ja hakemusmenettelyjen tueksi. Suunnitteluvaiheessa olevat terveydenhoito- ja hyvinvointialaan liittyvät living labit voivat hyödyntää tämän tutkimuksen tuloksia. OuluHealth Labsin suhde julkiseen sektoriin ja terveysalaan liittyvät erikoispiirteet, kuten lait ja säännökset tulee ottaa huomioon arvioitaessa tulosten sopivuutta yleiseen käyttöön

Testo completoAbstract (sommario):
Coastal wetlands are among the most significant, rich, productive, and sensitive ecosystems on Earth. However trends have shown an alarming deterioration during the last decades, as environmental development pressures are aggressively increasing in these areas. This has led to incremental international co~cern and the leads of this international movement, including RAMSAR convention on wetlands, the Convention on Bio-Diversity, and the Millennium Ecosystem Assessment are strongly recommending the Ecosystem Approach (EA) for planning and management to achieve sustainable development in these areas. However the EA is still in its evolutionary stage. Its basic principles and guidelines have been developed but the need for an integrated framework which translates these into a clear process of planning and management has been called for. In parallel: the Ecosystem Services Assessment (ESA) is increasingly recommended as an essential technique supporting the EA but this too is at early stage of development. From here, the aim of this research has been formed 'to develop the Ecosystem Approach and the Ecosystem Service Assessment for planning and management of coastal wetlands'. The research has integrated different research methods and data collection techniques in a series of research steps taken to reach this aim. They can be distinguished into three main stages, as follows: a) Constructing the EA Framework: This stage starts by discussing the special features and characteristics of coastal wetland ecosystems and the main development issues and global challenges they are facing; in order to extract the required characteristics of the proposed framework. Then, the Ecosystem Approach is critically discussed to highlight areas of strengths and weakness compared to the other environmental planning approaches. Several more developed features of the other approaches which address areas of weaknesses are identified then integrated in the suggested EA framework. Also, here the potential role of GIS and RS as powerful tools for environmental planning and management supporting the proposed framework are discussed; and more guidelines and lessons learned from international experiences related to applications of the EA in coastal wetlands are extracted. Finally, the results of all these elements are integrated into a suggested EA framework for planning and management of coastal wetlands. b) Designing an integrated Ecosystem Service Assessment (ESA) technique: This stage focuses on developing the recommended ESA as technique supporting the suggested framework. Two research steps are taken to reach this; developing a suitable procedure for the ESA technique, and designing suitable indicators for evaluation, and refining these through an online international expert survey to establish the final set of ESA indicators. c) Testing the applicability of the main outcomes of the research: The Egyptian context was selected as a rich representative case study for this stage. Several analyses of empirical data including interviews, focus groups, and archival data have been accomplished in order to get a reliable image of applicability of both the suggested EA framework and its integrated ESA technique. Promising results have been obtained not only regarding the applicability of these outcomes, but also for wider application; moreover the nomination for the RAMSAR scientific research Prize 2012.

Testo completoAbstract (sommario):
Internationally there is an increasing focus on involving local communities in natural resource management and monitoring. Monitoring methods which are professionally driven appear to be inadequate to deal with the monitoring of natural resource use and biodiversity conservation, globally. This is especially evident in areas such as South African rural communal land. Two community based natural resource management (CBNRM) programmes in areas which are communally governed in the Eastern Cape, South Africa, namely Nqabara and Machubeni, were used as part of this research study. This thesis identified and tested potentially simple and cost effective monitoring methods related to the utilization of the local rangelands and indigenous forests. The criteria that were tested include 1) appropriateness and effectiveness in measuring change, and 2) contribution to building adaptive capacity among local land managers through learning. The criteria were assessed using a scoring system for each monitoring method in order to evaluate their strengths and weaknesses . This was done by using both quantitative and qualitative data. Contribution to building adaptive capacity was assessed by evaluating technical capacity gained, local ecological knowledge contributed and learning by participants. This was done using qualitative data. The results show that the monitoring methods had different strengths and weaknesses in relation to the criteria, making them more appropriate for different priorities such as effectively measuring change or building adaptive capacity. It is argued that an adaptive approach is a useful component in the participatory monitoring process. An adaptive framework was developed from lessons learnt in this study for collaborative monitoring. Challenges such as low literacy levels and adequate training still need to be addressed to strengthen efforts towards participatory monitoring. Factors such as incentives, conflict and local values may negatively affect the legitimacy and sustainability of participatory monitoring and therefore also need to be addressed.

Testo completoAbstract (sommario):
It is widely known that the world is losing biodiversity and primarily it is thought to be caused by anthropogenic activities. Many of these activities have been identified. However, we still lack a clear understanding of the causal relationships between human activities and the pressures they place on the environment and biodiversity. We need to know how ecosystems and individual species respond to changes in human activities and therefore how best to moderate our actions and reduce the rate of loss of biodiversity. One of the ways to detect these changes is to use indicators of ecosystem conditions. Indicators are statistics following changes in a particular factor usually over time. These indicators are used to summarise a complex set of data, and are seen as being representative of the wider situation in that field. So it can be assumed that if that particular factor is declining or improving, then the situation in general is also declining or improving. They are used to check the status and trends of biodiversity by both the public and policy makers. Indicators are also used to assess national performance and can be used to identify the actions required at the policy level. In this manner, they provide an important link between policy-makers and scientists collecting the data. The current thesis investigates the possibility of using bird species as indicators of biodiversity for better management of natural terrestrial ecosystems, by identifying their habitats according to various environmental factors. The study is established by drawing upon three main scientific areas: ecology, geographical information system (GIS), and statistical modelling. The Mornington Peninsula and Western Port Biosphere Reserve (MPWPBR) (Victoria, Australia) was chosen for the study area because of the combination of suburban and natural environments that made it optimum for this type of study. Once the study area was defined, the necessary data for the research were obtained from various sources. Birds Australia provided data on recorded observation of 271 bird species within the study area. Based on the nature of this study, seven species were selected for the study. The criteria for this selection are discussed in Chapter 3. Most literature state that the primary determinant for bird abundance is vegetation and land cover. Because of this, Ecological Vegetation Class (EVC) layer was used to determine which type(s) of vegetation have the greatest impact on habitat selection. Each species showed a relationship to a number of v vegetation types. These EVCs were combined to produce vegetation patches, and were considered as potentially suitable habitats of corresponding bird species. For each of the species, these habitat patches were analysed for the different aspects of patch characteristics (such as the level of patchiness, connectivity, size, shape, weighted distance between patches, etc.) by using the Landscape Context Tool (a GIS add-on). This process assisted the understanding of the importance of patch quality in habitat selection among different bird species by analysing the location of bird observation sites relative to habitat patches. In this way, the association between bird presence and the conditions of a habitat patch was identified by performing a discriminant function analysis. To investigate the probability of a species presence according to different environmental factors, a model of species distribution was created. Binary logistic regression was used to indicate the level of effect of each variable. The model was then successfully validated in the field. To define the indicators of environmental factors, it was essential to separate bird species based on their dependency on one or more of the studied variables. For this purpose, One-Way ANOVA was used. This analysis showed that some bird species can be considered as indicators of urban areas, while others could be good indicators of wellpreserved large forests. Finally, it must be mentioned that the type and quality of the datasets are crucial to this type of study, because some species have a higher degree of sensitivity to certain types of vegetation or land cover. Therefore, the vegetation data must be produced as detailed as possible. At the same time, the species data needs to be collected based on the presence and absence (versus presence-only) of the birds.

Testo completoAbstract (sommario):
This dissertation follows the trajectory of fisheries management in British Columbia from a period prior to European contact when Aboriginal people encountered limits, learned to live within them and indeed enhance productivity of lands and waters. The diversity of ecological contexts and human experience created a rich diversity of eco-social-spiritual communities, sustained by the interweaving of scientific, economic, social, spiritual and aesthetic values. Since then, fisheries managed primarily for commodity value have depleted marine life, while the growth of other economic sectors has transformed ‘fisheries’ from a mainstay of culture and existence to a tiny fraction of BC’s economy as measured by GDP.
Globally, depletion and chronic undervaluing have prompted leading marine scientists, conservationists and others to call for a sea or ocean ethic. A literature review reveals a strong public demand for inclusion of immeasurable values between the lines of the ecological economics literature and in declarations from leading scientists and world religions, but there is no coherent way to implement it. A research project using Q methodology indicates that the public demand for inclusion of a spiritual dimension holds for a wide cross-section of people engaged in the governance, management and use of BC’s marine environment. The dissertation outlines a concept of the secular sacred based on a spirituality of dedicated attention to relationships. Dedicated attention confers the knowledge to enhance relationships that contribute to flourishing and unravel those that are destructive.
The secular sacred can draw on the moral authority of science to report objectively on large-scale relationships, the moral authority of Aboriginal and local people at local scale, the moral authority of ordinary people committed to flourishing of people, species and places, the moral authority of religion in terms of gratitude, generosity, compassion, love and justice and the moral authority of artists who can represent complexity and tension and point ways to sustainability which words cannot. Drawing on multiple sources of knowledge and authority without belonging to any of them, the secular sacred opens the door to transformative change in and beyond British Columbia.

As urban populations continue to grow around the world, cities and their residents become increasingly vulnerable to climate change risks. Detrimental impacts on natural ecosystems have been observed in the built environment, as well as poorer quality of life. As urban areas are characterised by complex adaptive systems, the concept of ecosystem services represents an important tool for the management of urban socio-environmental quality and can be applied to climate change adaptation and mitigation strategies. This thesis investigates London’s potential resilience to climate changes through ecosystem services management. In particular, the socioecological capacity of the All London Green Grid for contributing to climate change resilience via patterns of green spaces, and carbon storage and sequestration through urban street trees, will be the central focus in the research. This capacity was assessed firstly by conducting an evaluation of the landscape metrics of Greater London’s green spaces to determine the extent and quality of green infrastructure, and how this varies according to relevant socioeconomic variables. This was achieved using GIS and the spatial analysis programme FRAGSTATS. This broad-scale evaluation was then supported by greater in-depth field measurements, focusing specifically on street trees, within selected eleven Business Improvement Districts (BIDs), which are an important vehicle for the local management of the ALGG and thereby climate resilience. This local-scale assessment also incorporated greater evaluation of ecosystem service provision by vegetation, and in particular street trees and their capacity for carbon storage and sequestration. Finally, governance of green spaces within BIDs and broader understanding of resilience and climate change was assessed with qualitative research methods, including semi-structured interviews of different agents and agencies involved in the ALGG network. This included investigation of decision-makers’ perspectives on vulnerabilities and the prospects for further developing London green spaces, to determine the feasibility of different management options.

Testo completoAbstract (sommario):
Understanding how to balance human well-being and ecological integrity is one of the fundamental challenges in conservation and natural resource management. As our human-footprint on ecosystems expands and deepens, we are increasingly realizing that human well-being is crucial to understanding social-ecological systems and managing them sustainably.
In my first chapter I add to this literature by extending a theoretical model to examine the effects of two biophysical stressors on a marine species. While this model was developed to understand how harvest and climate change may interact to affect species viability, the model instead emphasized the sensitivity of the results to assumptions about human behavior. This result adds to a small, but growing, body of literature that demonstrates the importance of considering resource-users’ dynamics when attempting to predict outcomes for biophysical systems.
Despite conceptual advances in linking human-wellbeing to biophysical dynamics, a major challenge exists in operationalizing these conceptual framings. In my second chapter I use the US West Coast commercial fisheries system as a case study and developed a novel network approach of linking the social system (i.e. fishing communities) to the ecological system (the fish). This approach made use of data collected by management, making it immediately operational for all managed fisheries in the US. Such a conceptual framework represents a major step forward for mapping and quantifying these linkages between social and natural systems. I add to this work by analyzing these resultant networks to show that the topological structure and modularity varied non-randomly, providing additional features that may be useful for mangers seeking to balance human well-being with sustainable populations of fish.
In my third chapter I analyzed patterns of participation across the US West Coast commercial fisheries before and after a major management change in a single fishery. Using individual- and fishing community-level analyses, using the framework described above, I show that the policy affected how fishermen shift their effort across fisheries at the individual level, but community level attributes remain unchanged. This work demonstrates how such social-ecological system level policy analysis may be conducted.
Overall this dissertation helps move us towards a set of tools managers can use to evaluate policy efficacy in commercial fisheries in the face of rapid environmental change while balancing ecological integrity and human well-being.

Testo completoAbstract (sommario):
Issues connected with value of ecosystems got wide discussions during
recent years in context of its goods and services providing, but also
improving social and economic welfare. From an economic point of view,
ecosystems provide economic agents with significant advantages, or socalled
"ecosystem services". For example, forests provide raw materials for
wood processing industry, genetic resources give materials for breeding
and genetic engineering, rivers provide freshwater for household needs, and
wetlands reduce the impact of flooding and enable the development of
commercial fisheries. Therefore, the degradation of ecosystems entails not
only a number of risks for business activities, but will also jeopardize the
position of economic agents in the market.

Crandall, Lucas Earle. "Ecosystem-Based Management in the Morro Bay Watershed and Estuary". DigitalCommons@CalPoly, 2017. https://digitalcommons.calpoly.edu/theses/1723.
Testo completoAbstract (sommario):
The following thesis discusses the implementation of ecosystem-based management, an emerging concept in the field of environmental planning and management, in the Morro Bay watershed and estuary. Ecosystem-based management offers solutions to problems associated with human interaction within the natural environment; former President Barack Obama advised by the National Ocean Council, Pew Oceans Commission Report and the US Commission on Ocean Policy, has mandated implementation of this concept in coastal and marine systems (National Ocean Council, 2016). The theory behind ecosystem-based management challenges many tenets of existing natural resource management. This thesis finds the concept of ecosystem-based management as favorable despite tradeoffs and impacts of changing status quo. The preliminary research question asked if key criteria of ecosystem-based management were integrated into existing management plans of institutions such as the Coastal San Luis Resource Conservation District, Morro Bay National Estuary Program, and the San Luis Obispo Science and Ecosystem Alliance. The study answers this question through a document analysis of three local management plans. Survey and interviews were used to assess inconsistencies between management plan goals and on-the-ground implementation in the Morro Bay ecosystem. The results were used to incorporate tenets of ecosystem-based management into the Coastal San Luis Resource Conservation District’s five-year and annual strategic plan update.
