A service perspective to digital innovation: exploring the emergence of autonomous shipping

Current research describes digital innovation largely similar to product innovation. Digital innovation is seen as an object of coherent activities, however in reality digital innovation results from convergence of variant technologies and those related actors with versatile business goals. To account for the dynamic nature of digital innovation, this study applies a service perspective to digital innovation. The purpose of the study is to understand how digital innovation emerges within a service ecosystem for autonomous shipping. The sub-objectives of this study are to 1) identify what factors motivate and demotivate actors to integrate resources for autonomous shipping, 2) explore the key technology areas to be integrated to realise the autonomous shipping concept, and 3) suggest how the technology areas are combined for mutual value creation within a service eco-system for autonomous shipping. Insights from autonomous driving were also included. This study draws on literatures on service innovation and service-dominant logic. The research was conducted as a qualitative exploratory case study. The data comprise interviews of 18 marine and automotive industry experts, 4 workshops, 4 seminars, and observations as well as various secondary data sources. The findings revealed that the key actors have versatile motivations regarding autonomous shipping. These varied from opportunities for single applications to occupying a central role in an autonomous technology platform. Thus, autonomous shipping can be seen as an umbrella concept comprising multiple levels. In technical terms, the development of the concept of autonomous shipping is largely based on combining existing technology solutions, which are gradually integrated towards more systemic entities comprising areas of the autonomous shipping concept. This study argues that a service perspective embraces the inherently complex and dynamic nature of digital innovation. This is captured in the developed research framework that describes digital innovation emerging on different levels of interaction: 1. strategic relationships for new solutions, 2. new local networks for technology platforms, and 3. global networks for new markets. The framework shows how the business models and motivations of digital innovation actors feed the emergence of digital innovation in overlapping service ecosystems that together comprise an innovation ecosystem for autonomous technologies. Digital innovation managers will benefit from seeing their businesses as part of a larger ecosystem of value co-creating actors. In orchestrating digital innovation within a service ecosystem, it is suggested that managers consider the resources, roles and institutions within the ecosystem. Finally, as autonomous shipping is at its infancy, the topic provides a number of interesting avenues for future research.

Diel patterns and tissue-specificity of environmental responses in fish

Humans are profoundly changing aquatic environments through climate change and the release of nutrients and chemicals. To understand the effects of these changes on natural populations, knowledge on individuals’ environmental responses is needed. At the molecular level, the environmental responses are partly mediated by chances in messenger RNA and protein levels. In this thesis I study messenger RNA and protein responses to an assortment of environmental stressors in fish. As daily (diel) rhythms are known to be ubiquitous in different tissues, I particularly focus on diel patterns in the responses. The studied species are the three-spined stickleback (Gasterosteus aculeatus L.) and the Arctic char (Salvelinus alpinus L.), both of which have circumpolar distribution in the Northern hemisphere. In the first two studies, three-spined sticklebacks were exposed to both the non-steroidal anti-inflammatory drug diclofenac and low-oxygen conditions (hypoxia), and their responses measured at separate time points in the liver and gills. The results show how the seemingly unrelated environmental stressors, hypoxia and anti-inflammatory drugs, can have harmful combined effects that differ from the effects of each stressor alone. Moreover, both stressors disturbed natural diel patterns in gene expression. In the third study, I studied the responses of three-spined sticklebacks to two test chemicals: one used in hormonal medicine (17α-ethinyl-oestradiol) and one used as a plasticizer and solvent chemical (di-n-butyl phthalate). The results suggest that the phthalate can affect genes related to spermatogenesis in fish testes, while estrogen-mimicking compounds can lead to numerous disturbances in the endocrine system. In the final study, the temperature-dependence of diel rhythms in messenger RNA levels were evaluated in the liver tissue of the Arctic char, a cold-adapted salmonid. The results show that cold acclimation repressed diel rhythms in gene expression compared to warm-acclimated fish, in which the expression of hundreds of genes was rhythmic, suggesting the circadian clock of the Arctic fish species can be sensitive to temperature. Overall, the results of the thesis indicate that fishes’ responses to abiotic factors interact with their diel rhythms, and more studies on the consequences of these interactions are needed to comprehensively understand human impacts on ecosystems.

Critical elements underpinning the emergence of the medical game ecosystem:gamifying traumatic brain injury rehabilitation in Finland

The healthcare sector is currently in the verge of a reform and thus, the medical game research provide an interesting area of research. The aim of this study is to explore the critical elements underpinning the emergence of the medical game ecosystem with three sub-objectives: (1) to seek who are the key actors involved in the medical game ecosystem and identify their needs, (2) to scrutinise what types of resources are required in medical game development and what types of relationships are needed to secure those resources, and (3) to identify the existing institutions (‘the rules of the game’) affecting the emergence of the medical game ecosystem. The theoretical background consists of service ecosystems literature. The empirical study conducted is based on the semi-structured theme interviews of 25 experts in three relevant fields: games and technology, health and funding. The data was analysed through a theoretical framework that was designed based upon service ecosystems literature. The study proposes that the key actors are divided into five groups: medical game companies, customers, funders, regulatory parties and complementors. Their needs are linked to improving patient motivation and enhancing the healthcare processes resulting in lower costs. Several types of resources, especially skills and knowledge, are required to create a medical game. To gain access to those resources, medical game companies need to build complex networks of relationships. Proficiency in managing those value networks is crucial. In addition, the company should take into account the underlying institutions in the healthcare sector affecting the medical game ecosystem. Three crucial institutions were identified: validation, lack of innovation supporting structures in healthcare and the rising consumerisation. Based on the findings, medical games cannot be made in isolation. A developmental trajectory model of the emerging medical game ecosystem was created based on the empirical data. The relevancy of relationships and resources is dependent on the trajectory that the medical game company at that time resides. Furthermore, creating an official and documented database for clinically validated medical games was proposed to establish the medical game market and ensure an adequate status for the effective medical games. Finally, ecosystems approach provides interesting future opportunities for research on medical game ecosystems

Evaluation of the main energy scenarios for the global energy transition

Energy scenarios are used as a tool to examine credible future states and pathways. The one who constructs a scenario defines the framework in which the possible outcomes exist. The credibility of a scenario depends on its compatibility with real world experiences, and on how well the general information of the study, methodology, and originality and processing of data are disclosed. In the thesis, selected global energy scenarios’ transparency and desirability from the society’s point of view were evaluated based on literature derived criteria. The global energy transition consists of changes to social conventions and economic development in addition to technological development. Energy solutions are economic and ethical choices due to far-reaching impacts of energy decision-making. Currently the global energy system is mostly based on fossil fuels, which is unsustainable over the long-term due to various reasons: negative climate change impacts, negative health impacts, depletion of fossil fuel reserves, resource-use conflicts with water management and food supply, loss of biodiversity, challenge to preserve ecosystems and resources for future generations, and inability of fossil fuels to provide universal access to modern energy services. Nuclear power and carbon capture and storage cannot be regarded as sustainable energy solutions due to their inherent risks and required long-term storage. The energy transition is driven by a growing energy demand, decreasing costs of renewables, modularity and scalability of renewable technologies, macroeconomic benefits of using renewables, investors’ risk awareness, renewable energy related attractive business opportunities, almost even distribution of solar and wind resources on the planet, growing awareness of the planet’s environmental status, environmental movements and tougher environmental legislation. Many of the investigated scenarios identified solar and wind power as a backbone for future energy systems. The scenarios, in which the solar and wind potentials were deployed in largest scale, met best the set out sustainability criteria. In future research, energy scenarios’ transparency can be improved by better disclosure on who has ordered the study, clarifying the funding, clearly referencing to used sources and indicating processed data, and by exploring how variations in cost assumptions and deployment of technologies influence on the outcomes of the study.

Environmental assessment of Lake Gibson sediments, water quality, and soils of the Niagara Region

In light of the fact that literature on toxicity of heavy metals in non-acidified freshwater systems is sparse, this project was initiated to conduct an environmental assessment of Lake Gibson. Chemistry of soils from adjacent areas and vineyards in the region provide a comparative background database. Water quality determinations were used to identify and highlight areas of environmental concern within the Lake Gibson watershed. A Shelby Corer was used to obtain 66 sediment cores from Lake Gibson. These were sectioned according to lithology and color to yield 298 samples. A suite of 122 soil samples was collected in the region and vicinity of Lake Gibson. All were tested for metals and some for Total Petroleum Hydrocarbons (TPH). Evaluation of the results leads to the following conclusions: 1. Metal concentrations ofAI, Cd, Cu, Cr, Pb, Ni, Fe and Zn in soils from the Niagara Region are well below background limits set by the Ministry of the Environment and Energy (MOEE) for provincial soils. 2. There is a spatial and depth difference for some of the metals within the various soils. The Cr, Ni and Pb contents of soils vary throughout the region (pecosystems. 4. All other metal contents exceed the LEL, and in some instances they also exceed the SEL (Severe Effect Level) guideline. In this instance acute toxicity testing of 11 the sediments is required to assess impact on the aquatic biota. 5. Specifically, effluents and discharges from outfalls, roadways, railways and industrial activities are all degrading the local ecosystem. 6. Mineral oil and greases are a major environmental concern in the sediments of Lake Gibson. Ofthe 240 samples tested for TPH, 200 samples exceed the MOEE Open Water Disposal Guideline of 1,500 mg/kg. 7. Four areas within Lake Gibson are especially degraded with respect to TPH. One area is just downstream from the Old WeIland Canal divergence point and waterfall. Other areas of concern are located just south of Beaverdams Road and just west ofthe Ontario Hydro control pipes; south ofthe Village ofBeaverdams. The fourth area of environmental concern and TPH impact is located between Highway 406 and Merrittville Highway.

Investigating the potential of thecamoebians (testate amoebae) as bio-indicators of impact of oil sands mining operations on freshwater environments in Northeastern Alberta, Canada

Thecamoebian (testate amoeba) species diversity and assemblages in reclamation wetlands and lakes in northeastern Alberta respond to chemical and physical parameters associated with oil sands extraction. Ecosystems more impacted by OSPM (oil sands process-affected material) contain sparse, low-diversity populations dominated by centropyxid taxa and Arcella vulgaris. More abundant and diverse thecamoebian populations rich in difflugiid species characterize environments with lower OSPM concentrations. These shelled protists respond quickly to environmental change, allowing year-to-year variations in OSPM impact to be recorded. Their fossil record thus provides corporations with interests in the Athabasca Oil Sands with a potential means of measuring the progression of highlyimpacted aquatic environments to more natural wetlands. Development of this metric required investigation of controls on their fossil assemblage (e.g. seasonal variability, fossilization potential) and their biogeographic distribution, not only in the constructed lakes and wetlands on the oil sands leases, but also in natural environments across Alberta.

Buried Treasure: The Economics of Leak Detection and Water Loss Prevention in Ontario

On average approximately 13% of the water that is withdrawn by Canadian municipal water suppliers is lost before it reaches final users. This is an important topic for several reasons: water losses cost money, losses force water agencies to draw more water from lakes and streams thereby putting more stress on aquatic ecosystems, leaks reduce system reliability, leaks may contribute to future pipe failures, and leaks may allow contaminants to enter water systems thereby reducing water quality and threatening the health of water users. Some benefits of leak detection fall outside water agencies’ accounting purview (e.g. reduced health risks to households connected to public water supply systems) and, as a result, may not be considered adequately in water agency decision-making. Because of the regulatory environment in which Canadian water agencies operate, some of these benefits-especially those external to the agency or those that may accrue to the agency in future time periods- may not be fully counted when agencies decide on leak detection efforts. Our analysis suggests potential reforms to promote increased efforts for leak detection: adoption of a Canada-wide goal of universal water metering; development of full-cost accounting and, pricing for water supplies; and co-operation amongst the provinces to promulgate standards for leak detection efforts and provide incentives to promote improved efficiency and rational investment decision-making.

Niagara River (Ontario) Remedial Action Plan fonds, 1984-1997, n.d.

The Niagara River Remedial Action Plan was part of an initiative to restore the integrity of the Great Lakes Basin ecosystem. In 1972, the Great Lakes Water Quality Agreement was signed by both Canada and the United States to demonstrate their commitment to protecting this valuable resource. An amendment in 1987 stipulated that Remedial Action Plans (RAPs) be implemented in 43 ecologically compromised areas known as Areas of Concern. The Niagara River was designated as one of these areas by federal and provincial governments and the International Joint Commission, an independent and binational organization that deals with issues concerning the use and quality of boundary waters between Canada and the United States. Although the affected area included parts of both the Canadian and American side of the river, Remedial Action Plans were developed separately in both Canada and the United States. The Niagara River (Ontario) RAP is a three-stage process requiring collaboration between numerous government agencies and the public. Environment Canada, the Ontario Ministry of the Environment, and the Niagara Peninsula Conservation Authority are the agencies guiding the development and implementation of the Niagara River (Ontario) RAP. The first stage is to determine the severity and causes of the environmental degradation that resulted in the location being designated an Area of Concern; the second stage is to identify and implement actions that will restore and protect the health of the ecosystem; and the third stage is to monitor the area to ensure that the ecosystem’s health has been restored. Stage one of the RAP commenced in January 1989 when a Public Advisory Committee (PAC) was established. This committee was comprised of concerned citizens and representatives from various community groups, associations, industries and municipalities. After several years of consultation, the Niagara River (Ontario) Remedial Action Plan Stage 2 Report was released in 1995. It contained 16 goals and 37 recommendations. Among them was the need for Canadians and Americans to work more collaboratively in order to successfully restore the water quality in the Niagara River. Stage three of the Niagara River (Ontario) RAP is currently ongoing, but it is estimated that it will be completed by 2015. At that point, the Niagara River Area of Concern will be delisted, although monitoring of the area will continue to ensure it remains healthy.

L’intégration du milieu naturel dans l’aménagement de quartiers de banlieue : le cas du Faubourg de la Pointe-aux-Prairies, Montréal

Les nombreux exemples réussis où l’aménagement du territoire intègre des milieux naturels nous ont amenée à nous questionner sur les techniques d’intégration des milieux naturels et les outils de planification disponibles au Québec. La présente recherche porte sur le volet environnemental du projet résidentiel le Faubourg de la Pointe-aux-Prairies à Montréal (FPP) situé dans l’Arrondissement Pointe-aux-Trembles/Rivière-des-Prairies/Montréal est. Un premier objectif relié aux résultats nous a permis d’analyser le taux de succès du quartier FPP à intégrer efficacement des préoccupations environnementales concernant la mise en valeur des milieux naturels. En nous basant sur le taux de conservation, l’intégrité écologique et les témoignages des intervenants de la Ville de Montréal, nous avons déterminé que le plan d’aménagement du projet présente un bilan environnemental mitigé. Un second objectif relié aux processus nous a permis de déterminer si les outils sollicités pendant la conception et la mise en œuvre du projet ont facilité l’intégration des milieux naturels. En nous basant sur les outils d’encadrement et proactifs utilisés tout au long de la mise en oeuvre, nous avons déterminé que ceux-ci sont inadaptés à certaines situations. La non intégration des milieux protégés dans les outils de planification, la destruction des milieux aquatiques avec l’accord du Ministère de l’environnement (MDDEP), le manque de vérification des ententes lors de l’attribution des certificats d’autorisation, l'absence de protection des milieux naturels terrestres et la difficulté d’évaluer les bénéfices économiques de l’intégration de la nature ont été les défis majeurs observés.

Évaluation des écosystèmes en début de millénaire: conclusions et retombées

L'évaluation des écosystèmes est l'un des pivots essentiels pour l'élaboration de moyens adaptés permettant de lutter contre la diminution massive de la biodiversité. Pour la première fois, elle a fait l'objet d'une analyse à l'échelle mondiale dans le cadre de l'Evaluation des écosystèmes en début de millénaire (EM). Le rassemblement de plus d’un millier de chercheurs et de plusieurs organismes internationaux durant quatre années ont permis de dessiner la carte nécessaire à toute action efficace. L'article expose les éléments principaux de l'EM : l'évaluation des écosystèmes en tant que tels, mais surtout des services écosystémiques, dans toutes leurs dimensions, en ce que leur évolution affecte le bien-être humain. Il analyse ensuite les quatre points principaux de l'apport de l'EM, des avantages de l'utilisation croissante des services écologiques à sa non viabilité. Des scénarios, modèles et outils sont proposés pour inverser la courbe négative d'appauvrissement de la biodiversité et des services écosystémiques dans un premier bilan des retombées de l'EM.

Impact des polluants agricoles sur la génétique des populations d’une espèce sentinelle : le ouaouaron (Rana catesbeiana)

L’expansion agricole ne cesse d’agir sur la perte d’habitats essentiels et nécessaires au développement des espèces. Bien que plusieurs espèces réussissent à survivre dans ces habitats peu adéquats, la persistance et la santé de plusieurs populations semblent compromises par l’utilisation souvent intensive de polluants chimiques agricoles et de fertilisants. Cette étude a pour but de déterminer l’impact des contaminants et de l’écologie du paysage sur la diversité génétique des populations de ouaouarons retrouvées en milieu agricole. Notre hypothèse de départ stipule qu’une exposition chronique aux polluants agricoles induira des différences génétiques au niveau des populations exposées. Le bassin versant de la rivière Yamaska a été désigné comme site d’étude puisqu’il fait partie de la région agricole la plus importante du Québec et parce qu’on y retrouve un gradient d’utilisation des terres pour l’agriculture (faible, moyen, élevé). Le ouaouaron a été choisi à titre de modèle biologique puisque ses caractéristiques physiologiques et écologiques en font une espèce sentinelle capable de rendre compte de l’état de santé global des écosystèmes. La caractérisation génétique des populations a été effectuée à partir de marqueurs d’AFLP (Amplified Fragment Length Polymorphism). Les résultats montrent que la diversité génétique est liée à la colonisation à partir de l’embouchure de la rivière Yamaska et que quelques populations sont génétiquement différenciées. De plus, nous avons démontré une relation positive entre le nombre de locus polymorphes et l’atrazine, l’indice de contamination et le métolachlore et la concentration en azote ainsi qu’entre l’hétérozygotie attendue et la concentration en phosphate.

Dynamique de la biodiversité dans la Serra do Itajaí, Brésil : une approche bioacoustique de la conservation

Le suivi des populations animales et végétales nous a amené à constater une perte importante de la diversité biologique. Les objectifs de la Convention sur la diversité biologique à atteindre pour 2010 sous-tendent la poursuite détaillée de ce suivi à l’échelle mondiale (CBD 2000). Cependant, il est difficile d’avoir une perception d’ensemble de la biodiversité d’un territoire, car les écosystèmes sont des entités dynamiques et évolutives, dans l’espace et dans le temps. Le choix d’un indicateur relevant de l’ensemble des ces caractéristiques devient donc primordial, bien qu’il s’agisse d’une tâche laborieuse. Ce projet propose d’utiliser la bioacoustique comme indicateur environnemental pour faire le suivi des espèces animales en milieu tropical. Afin de faire un suivi à une échelle régionale de la biodiversité, et ce, dans l’un des biomes les plus menacés de la planète, soit celui de la Mata Atlântica brésilienne, ce projet de recherche a comme objectif général de démontrer qu’il est possible d’associer la biophonie (événements sonores), à des événements biologiques (la richesse spécifique animale) en quantifiant des événements sonores (à l’aide des chants produits par les oiseaux, les insectes chanteurs de même que par les anoures) et en tentant de les associer aux fluctuations de la biodiversité. En plus de répondre à cet objectif général, trois objectifs spécifiques ont été définis : 1) comparer la biophonie et l’anthropophonie de milieux soumis à différents niveaux d’anthropisation ou de conservation afin d’évaluer l’impact anthropique sur le milieu, 2) évaluer la variabilité spatiale de la biodiversité, de même que 3) sa variabilité temporelle. Les résultats ont démontré que la biophonie est représentative de la biodiversité d’un milieu, et ce, même dans des conditions de biodiversité maximale puisqu’il existe une très forte relation entre les deux variables. De plus, les résultats révèlent une différence significative dans le ratio anthropophonie/biophonie de milieux soumis à différents niveaux de protection du territoire. La différenciation d’indices de puissance relative (dB/kHz) nous indique également l’importance de la variabilité spatiale et temporelle de la biodiversité, et par conséquent, l’importance de faire le suivi des espèces dans divers milieux et à diverses périodes afin d’obtenir une vision adéquate de la biodiversité régionale.

Entre conservation et développement local : étude des projets écotouristiques dans deux groupes quechua au Pérou

Depuis les années 1980, les projets intégrés de conservation et de développement (PICD) sont des modèles fonctionnels de développement durable. L’écotourisme est une de ces stratégies, combinant les objectifs sociaux et économiques de développement pour les populations locales dans un contexte de conservation des ressources naturelles. Cette maîtrise étudie un projet écotouristique réalisé dans la zone de transition du parc national Huascarán (Pérou) dans deux communautés quechuaphones, Vicos et Humachucco. Un PICD « réussi » combine la participation et la satisfaction des besoins de la population tout en contribuant à la conservation des écosystèmes. Cette étude a donc deux objectifs principaux : 1) une analyse de la participation pour mieux comprendre si et comment ce projet a su impliquer les populations et pour connaitre les facteurs favorisant un partenariat entre différents acteurs du projet; 2) une analyse des impacts environnementaux, économiques et socioculturels de l’écotourisme pour déterminer si les besoins des populations et les objectifs du projet ont été atteints, apportant ainsi une nouvelle dynamique à la communauté. La méthodologie combine les approches de l’écologie culturelle, de l’approche exploratoire et de l’étude de cas. Les données sont issues du terrain de recherche, soit des données écrites, de l’observation participante et des entretiens semi-dirigés. Elles ont été traitées en utilisant différentes grilles d’analyse. Les résultats démontrent que, malgré un manque de clarté et de transparence, de nombreux efforts ont permis de favoriser la participation et d’impliquer la population locale, créant des impacts économiques favorables.
