Gomes, Rafael, und Sema Seyfi Osman. „Managing Organizational Adoption of IoT : Revisiting Rogers' Diffusion of Innovation Theory“. Thesis, Uppsala universitet, Industriell teknik, 2019. http://urn.kb.se/resolve?urn=urn:nbn:se:uu:diva-398123.

As a disruptive innovation, IoT has been creating a high impact over organizations’ current strategies and business models. This continuous process of change will have an increasing influence on how organizations and industries as a whole conduct their businesses, and is set to have an active role towards the development of entirely new business models and markets. With the development of IoT technologies, and its predicted exponential spread across all sectors of society, one can conclude that the future holds many opportunities for organizations looking to explore new ways of capturing and creating value, but at the same time there are also plenty of challenges to be addressed. While the diffusion and adoption process of IoT has been an ongoing phenomenon over the past decade, there is still not much certitude as to how organizations ought to adjust in order to successfully integrate IoT technologies in their structure and operations. In parallel fashion, there have also been many difficulties in ensuring that different smart, connected devices and ecosystems are able to effectively communicate between each other, as achieving interoperability has become one of the major concerns associated with IoT. The main focus of this study is to analyze the process of how organizations are currently integrating IoT within their businesses, while also investigating causes that hinder interoperability, and evaluating the future potential deployment of the Open IoT ecosystems in companies. For our research we have followed a case-study approach where we conducted semi-structured interviews with managers and project leaders from two organizations conducting pilot studies on Green IoT and Open IoT, and where one has been adopting IoT technologies in its business. Theoretically, we draw on a framework by combining Rogers’ Diffusion of Innovations theory and Christensen’s theory of Disruptive Innovations in order to analyze the integration of IoT into businesses’ core structure. The research goes through a functional framework that outlines the process of IoT adoption while also presenting the present challenges that are faced by the actors in the industry and the key enablers for successful IoT integration.

In this study, two implementable leadership products were analogous to innovations, when framed in the context of Rogers’ diffusion-of-innovation theory. Thus, the products’ respective dissemination patterns were compared and contrasted-- quantitatively through purchase numbers, and qualitatively through opinions and events recollected by early users. The case-study approach was central to the investigation, and the results supported the Rogers model with regard to most constructs. The results pertaining to the S-shaped (sigmoidal) prototypical distribution curve, however, were enigmatic. The inverse conformity of sales figures with the S-shaped distribution curve implied that the dissemination process began during the field-testing stage rather than the purchasing stage. The organizational structure of the user institutions (targeted social system construct) conformed to Rogers’ theory that autonomy and teamwork characterized management climates where innovation tended to flourish. Field-testers and other early users were opinion leaders as construed by Rogers. The fact that twice as many field tests were conducted for the Case Studies as for the Simulation was likely a factor in the disparate 6:1 ratio of units of Cases sold to units of the Simulation sold for three consecutive years.
Other factors possibly accounting for the disparate sales came from the attributes-of-innovation template which framed five generic attributes--compatibility, relative advantage, complexity, trialability, and observability. Both products conformed to the attributes as conceptualized by Rogers. The main difference that influenced the disparate sales was the greater complexity of the Simulation than of the Cases, although cost may have been a compatibility/relative advantage contributory factor. Finally, the study’s results indicated that dissemination parameters may have been narrowed by (a) the absence of mass media communication channels as part of the dissemination strategy at the awareness stage, and (b) lack of market research to focus the naming and packaging of the products for optimum compatibility and relative advantage. Researchers and change agencies can use these findings to improve future dissemination strategies and product designs.Ph. D.

Blended/hybrid learning, a combination of face to face and online learning to deliver instruction, is growing in popularity at institutions of higher education, and may lead to many benefits for students, faculty, and administrators. However, the implementation of blended learning (BL) is a complex process. Although the move towards BL adoption is generally accepted by faculty, questions still remain when it comes to adopting and implementing standards across institutions. Given this problem, this integrative literature review was conducted to identify possible factors that impact the process of implementing BL smoothly and successfully at higher education institutions. The purpose of this study was to identify related institutional factors from empirical studies published from 2000 to 2020. Findings from this study may offer institutions a guide to effectively create, execute, and assess BL programs and courses. The study provides recommendations that may be impactful for decision-makers at Saudi higher education institutions.Doctor of Philosophy
Blended/hybrid learning, a combination of face to face and online learning to deliver instruction, has become popular at universities because it provides advantages for students, faculty members, and the university itself. However, the implementation of blended learning (BL) is a challenging process, and in many instances there is not enough guidance available to assist universities through the process. For this reason, this study has been conducted with the goal of identifying possible factors relating to implementing BL smoothly and successfully at universities. Findings from this study may offer institutions a guide to effectively create, execute, and assess BL programs and courses. The study provides recommendations that may be impactful for decision-makers at Saudi universities

The inefficient use and knowledge of direct, on-demand air taxi/air charter flights in the United States was the topic of this dissertation. The general problem studied was the inefficient use of air transportation options by business travelers in the United States. The specific problem was how business travelers in the United States learn of and thereby elect to embrace a newer air travel option. Using Rogers's diffusion of innovations theory as the framework, the dissemination of air travel choices made by business travelers using ImagineAir air taxi service in the United States was explored via a qualitative case study research design methodology. Thirty-five semistructured interviews and matching customer database information provided data for the study, Data were later analyzed for emergent themes and codes using MAXQDA software. Key research questions included communication of the innovation, business travelers' perceptions of the innovation, timeframe of innovation adoption, business environment enabling the innovation adoption, and the Rogers self-described adopter type. The results showed that compatibility, relative advantage, risk, and complexity influence the perception of business travelers about air taxi services. Based on the research, the course of action suggests that business travelers will most rapidly embrace air taxi service via internet dissemination of this new option. With continued success in dissemination, positive social change will come in the form of efficiencies as business travelers use more than 5,000 virtually idle airports and over 7,000 on-demand air taxi aircraft as highlighted by U.S. government studies further bolstered by this research.

When compared to other industries, the construction industry has been slow to adopt digital technologies. BIM stands for Building Information Modeling (hereon referred to as BIM) and it represents a turning point when it comes to digitalization in the AEC sector. Despite BIM’s proven potential to reduce costs and improve the efficiency of construction projects, widescale adoption, and implementation of construction projects using BIM hasn’t happened yet. This research aims to conduct an innovation analysis of adoption of BIM in Europe using innovation theories such as Rogers’s diffusion theory and Crossing the Chasm by Moore. We hope the reader will have an understanding of the various adoption barriers for BIM in Europe after reading this research paper.Jämfört med andra branscher har byggbranschen varit långsam med att använda digital teknik.

Trots BIM: s beprövade potential att minska kostnaderna och förbättra effektiviteten i byggprojekt, har vidsträckt antagande och genomförande av byggprojekt med BIM ännu inte hänt. Denna forskning syftar till att göra en innovationsanalys av antagandet av BIM i Europa med hjälp av innovationsteorier som Rogers diffusionsteori och Crossing the Chasm av Moore.

The adoption and integration of technology is limited in K-12 contexts worldwide, including in the Middle East. Based on the work of Everett Rogers (1995) and his disciplines, studies in the United States indicate that teachers' perceptions towards the attributes of technology (relative advantage, compatibility, complexity, trialability and observability) reflect the extent by which technology is used. Furthermore, teachers' characteristics and the support environment provided can potentially encourage or inhibit the adoption of technologies. This multiple case study was designed to show the applicability of Rogers' diffusion of innovation theory in Kuwait public school systems. The study was conducted with eight female Kuwaiti teachers in two primary public schools. A qualitative methodology was employed using interviews, participant observations, and physical artifacts for collecting data.
The study reveals that Rogers' three attributes relative advantage, compatibility and observability (result demonstrability) contributed to use, while complexity and observability (visibility) limited use. Prior experience and practice, motivational support provided by the school administration and department head, and teachers' voluntary decisions on the type of technologies to use encouraged use. Anxiety from lack of functionality of devices and extra time and effort in preparing materials, centralized decision-making on technology purchases, budget constraint, and limited access to technology and classrooms in which devices are located were factors that limited teachers' use. The study showed that Kuwaiti teachers' acceptance of technology varied along the continuum, where some teachers were early adopters and some were laggards. Support initiatives are needed from the Ministry of Education and school administration, in order to facilitate technology adoption and use in Kuwaiti schools.Ph. D.

Autonomous, otherwise known as self-driving, vehicles represent the future of transportation. Vehicles that drive themselves offer far reaching benefits from increased leisure and productivity for individuals to significant improvements in congestion and infrastructure for governments. The autonomous car will radically change the way we look at transportation, and they are right around the corner. However, the question remains: are we ready? Are we, as a society, ready to hand over the steering the wheel and trust autonomous vehicles with our safety? This paper predicts how the autonomous car will spread through society by analyzing and applying the product qualities and consumer types described in Everett Rogers’ Diffusion of Innovations Theory. Corporations, specifically Uber and Amazon, as opposed to individual consumers, will be the first to adapt, purchase and implement autonomous vehicles. Contrary to popular belief, these vehicles will not be successfully introduced as privately owned vehicles, and therefore, must be marketed towards corporations and organizations.

In light of the growing e-commerce and rising population in cities, along with the ongoing climate crisis, the efforts to improve transportation options are intensifying. Thus, the field of last-mile delivery, i.e., the last stretch of transportation to an end customer, is becoming an increasingly researched topic. Innovative delivery solutions, leveraging novel technology or business concepts, are quickly becoming a necessity to retain customer satisfaction while performing sustainable and cost-efficient deliveries. Facing the challenges associated with the last mile is especially arduous in the context of large goods, i.e., packages which are significantly larger than parcels that would fit in a regular mail or post box, and may include furniture, home appliances and other bulky tools. Despite that large goods delivery comprises a large market, there is limited research on how novel last-mile delivery innovations, mainly discussed for application on parcels, can be deployed for larger items. This thesis is an explorative and qualitative study which starts in a background of important trends in transportation, and moves on to provide an analysis of three cities (Barcelona, San Francisco and Seoul), as well as a fourth city (Stockholm) that is both analyzed and considered for implementation. This is done in the form of a case study where data is collected from a literature review as well as interviews with representatives from the company IKEA. Various last-mile delivery concepts are explained and analyzed with Rogers’ diffusion of innovation framework. The research generated insights on how a mixture of different solutions have emerged on the studied markets, mainly based on social, technological and regulatory factors. Although most of them would be theoretically usable for medium to large goods in the future, there are different obstacles to a commercial-scale adoption today, with technological and regulatory maturity being main hurdles. Parcel deliveries play a part in driving customer expectations forward, forcing large goods retailers to evolve their deliveries in order to not lose business. Ecosystems of delivery solutions are likely to emerge in the future, catering to customers’ flexibility demands. In terms of concrete solutions, e-cargo bikes, pick-up points and neighbourhood deliveries are identified as appropriate for the current market state of Stockholm and related third party agreements, physical properties and platforms are discussed in the context of implementation. Additionally, suggestions for future research is to consider further models for generalizing implementation requirements, along with deepening the analysis of last-mile delivery ecosystems by looking into actors for the suggested solutions.I och med ökande e-handel och stigande befolkning i städer, i kombination med en pågående klimatkris, intensifieras ansträngningar för att förbättra existerande transportalternativ. Därmed ökar mängden av forskning som fokuserar på last-mile delivery (ungefär sista milen-leverans), med andra ord den sista biten av en transportsträcka innan en vara når slutkunden. Innovativa leveranslösningar, som drar nytta av ny teknik eller nya affärsmodeller, håller snabbt på att bli en nödvändighet för att upprätthålla kundnöjdhet, samtidigt som leveransers kostnadseffektivitet och hållbarhet måste säkerställas. Utmaningarna som är associerade med sista milen är särskilt svårlösta när det kommer till stort gods, vilket är kollin som är signifikant större än vanliga paket som skulle få plats i en brevlåda eller postbox, och inkluderar bland annat möbler, vitvaror och andra skrymmande varor. Trots att leverans av stort gods utgör en omfattande marknad så är den befintliga forskningen begränsad vad gäller hur nya last-mile-innovationer kan användas för stort gods; detta diskuteras framförallt i samband med vanliga paket. Denna uppsats är en explorativ och kvalitativ studie som tar avstamp i en bakgrund som beskriver viktiga transporttrender och vidare analyserar tre städer (Barcelona, San Francisco och Seoul), samt en fjärde stad (Stockholm) som både analyseras och diskuteras för potentiell implementation. Detta utförs i form av en fallstudie där datan inkluderar en litteraturstudie samt intervjuer med representanter från företaget IKEA. Flertalet last-mile-leveranskoncept förklaras och analyseras med Rogers’ teori för innovationers spridning. Studien gav insikter om hur en blandning av olika lösningar har uppkommit på de undersökta marknaderna, i huvudsak beroende av sociala, tekniska och legala faktorer. Fastän de flesta i teorin skulle kunna appliceras på medelstort till stort gods i framtiden så finns det idag olika svårigheter som bromsar införandet av dessa på en kommersiell skala; teknisk och legal mognad verkar vara de huvudsakliga hindren. Paketleveranser spelar en viktig roll i att driva på kundernas förväntningar, vilket tvingar försäljare av stora varor att utveckla sina leveranser för att inte tappa sin omsättning. Ekosystem av leveranslösningar kommer troligen att utvecklas i framtiden för att möta kundernas krav på flexibilitet. Vad gäller konkreta lösningar identifieras elektriska lastcyklar, upphämtningsställen och grannskapsleveranser som passande för dagens Stockholm, och följande tredjepartsavtal, fysiska egenskaper och plattformar diskuteras i implementationssammanhang. Fortsatt föreslås framtida studier att överväga ytterligare modeller för att vidareutveckla och generalisera implementationskrav, samt att fördjupa analysen av ekosystem relaterade till last-mile-leveranser genom att undersöka involverade aktörer för de föreslagna lösningarna.

In the first essay, I examine value created through external acquisition of nascent technology innovation. External acquisition of new technology is a growing trend in the innovation process, particularly in high technology industries, as firms complement internal efforts with aggressive acquisition programs. Yet, despite its importance, there is little empirical research on the timing of acquisition decisions in high technology environments. I examine the impact of target age on value created for the buyer. Applying an event study methodology to technology acquisitions in the telecommunications industry from 1995 to 2001, empirical evidence supports acquiring early in the face of uncertainty. The equity markets reward the acquisition of younger companies.
In sharp contrast to the first essay, the second essay examines the diffusion of negative innovations. While destruction can be creative, certainly not all destruction is creative. Some is just destruction. I examine two fundamentally different paths to information security compromise an opportunistic path and a deliberate path. Through a grounded approach using interviews, observations, and secondary data, I advance a model of the information security compromise process. Using one year of alert data from intrusion detection devices, empirical analysis provides evidence that these paths follow two distinct, but interrelated diffusion patterns. Although distinct, I find empirical evidence that these paths both converge and escalate. Beyond the specific findings in the Internet security context, the study leads to a richer understanding of the diffusion of negative technological innovation.
In the third essay, I build on the second essay by examining the effectiveness of reward-based mechanisms in restricting the diffusion of negative innovations. Concerns have been raised that reward-based private infomediaries introduce information leakage which decreases social welfare. Using two years of alert data, I find evidence of their effectiveness despite any leakage which may be occurring. While reward-based disclosures are just as likely to be exploited as non-reward-baed disclosures, exploits from reward-based disclosures are less likely to occur in the first week after disclosure. Further the overall volume of alerts is reduced. This research helps determine the effectiveness of reward mechanisms and provides guidance for security policy makers.

In this paper we consider the spread of modern technological innovations. We contrast social learning and threshold heterogeneity models of innovation diffusion, and show how the typical temporal evolution of the distribution of adopters may be consistent with either explanation. Noting the likelihood that each model contains some useful independent explanatory power, we introduce a combined model. We also consider a spatially-structured population in which the spread of an innovation by social influence is modelled as a reaction-diffusion system, and show that the typical spatiotemporal evolution of the distribution is also consistent with a heterogeneity explanation. Additional contextual information is required to estimate the relative importance of social learning and of economic inequalities in observed adoption lags.

In the existing literature, studies of innovativeness usually focus on individual characteristics with little concern for aggregated behaviour; the central role of innovativeness, opinion leadership, and geographic location have not been fully reflected in diffusion models; most diffusion models either make simplified as-sumptions to model aggregated trends or concern individual behaviours exces-sively as being ‘toy models’; understandings of the diffusion forces bifurcate into explanations on social contagion effect and self-conformity effect and few diffu-sion models have tried to combine these two streams of thinking. In order to contribute knowledge to these fields, this study seeks to model the diffusion process from an agent-based perspective, with a specific focus on the effects of organisational innovativeness, opinion leadership, and geographic location. The proposed model is a focusing tool that helps interpret and organise the empirical observation. In turn, the model’s results could raise further questions for empiri-cal exploration. The result from the model simulation echoes a number of existing works on in-novation strategies with further quantitative implications for both industry policy makers and managers in organisations. It is found that the statistical distributions of organisational innovativeness and opinion leadership are both important fac-tors in diffusion; the level of information flow between organisations with differ-ent innovativeness levels influences the diffusion process significantly; to cluster organisations in one area changes the interactions between them and increases the diffusion rate, even when the average interaction level of the system is con-trolled. The model also indicates that organisations’ self-effort is the only way for being innovators; that factors that are related to interactions with others are more important for laying in the majority category; and that laggards normally adopt innovations by ‘luck’.

Global sustainable energy and environmental policies have increased the need to understand how new energy innovations diffuse into the market. The transport sector is currently a major source of unsustainable energy use contributing ~20-25% global CO2 emissions. Although the potential benefits of alternative fuel vehicle (AFV) technologies to reduce CO2 emissions and fossil fuel dependency have been demonstrated, many uncertainties exist in their market diffusion. It is also not well understood how policy can influence rapid diffusion of AFVs. To transition to a more sustainable energy-transport system, we need to understand the market conditions and factors necessary for triggering widespread adoption of new energy innovations such as AFVs. Modelling the diffusion of innovations is one way to explain why some ideas and technologies spread through society successfully, while others do not. These diffusion processes are characterized by non-linear interactions between heterogeneous agents in complex networked systems. Diffusion theory has typically been applied to consumer durable goods but has found less application to new energy and environmental innovations. There is much scope for advanced diffusion methods to inform energy policy. This depends upon understanding how consumer behaviour and technologies interact and can influence each other over time. There is also need to understand the underlying mechanisms that influence adoption behaviour among heterogeneous agents. This thesis tackles the above issues using a combination of empirical data analysis, scenarios, and simulation modelling as follows: 1) We first develop the empirical basis for assessing innovation diffusion from a technology-behavioural perspective, where we explicitly account for interactions between consumer preferences and technological performance across different spatial and temporal scales; 2) Scenarios are then used to disaggregate consumer markets and analyze the technological and behavioural factors that might trigger large-scale adoption of AFVs; 3) We then case-analyze the UK transport sector and develop a model of the dynamics between how vehicle technologies and consumer preferences can change and influence the diffusion process; 4) Finally, we develop exploratory simulations to assess how social network effects can influence individual adoption behaviour; 5) We close with policy implications of our findings, contributions and limitations of the thesis, and possible avenues for taking the research forward.

Many innovations fail on the market. Non-adoption and slow diffusion represent a high risk for companies in technology-intensive industries when looking to innovate, develop, market and launch a new technology. Its diffusion in the market is a major challenge for marketing. The consequence of a failed market introduction can be financial and reputational loss. Diffusion of innovation research shows a short-coming of researching barriers and challenges which prevent new technologies from being successful. This research sheds some light in the diversity, importance and existence of barriers for the diffusion of innovation. The originality of this investigation is a mixed-methods approach to explore barriers and challenges for the diffusion of innovation. An exploratory qualitative research is performed on the unique case of digital radio diffusion in Germany. Barriers evolve by this method in addition to barriers, which so far are described in a theoretical framework. These barriers are researched empirically via an international survey with close to one thousand participants representing experienced practitioners in marketing and sales positions from different industries. Various research findings are presented. The evolving barriers are researched and show circumstances of today, such as the dominance of internet, environmental awareness or the importance of inter-industrial collaboration. Additionally, diffusion barriers from a theoretical framework are tested with empirical data. Findings are presented as evidence for diffusion barriers and their importance for the specific example of digital radio is explained. Furthermore, barriers are also generalized for different technology-intensive industries. The existence of barriers is confirmed by empirical data and patterns of variations are outlined. Validity is achieved via triangulation of methodologies and supporting literature. The findings are presented to extend the theoretical framework and to close a gap in diffusion of innovation theory. The research contributes in very different ways to existing knowledge. Apart from the theoretical contributions, methodological and practical contributions are also made. With quantitative research, the sampling strategy for an online questionnaire considers the benefits of professional social networks on a global level to contribute empirical data to a theoretical framework. The practical contribution is directed to industry stakeholders and practitioners such as in marketing. The research findings result in a framework of barriers and supporting illustrations for technology-intensive industries. Practitioners can benefit from the illustrations for strategic decision-making in business development, product and general management, marketing and sales.

Cette thèse étudie l’effet des Droits de Propriété Intellectuelle (DPI) sur l’économie. Elle se sert d’un cadre commun (i.e. un modèle de croissance endogène avec différentiation horizontale) pour modéliser les DPI, identifier les coûts et bienfaits associés à leur mise en œuvre, suggérer un niveau de protection optimal en tenant compte des différences dans la composition des dotations de travail et, finalement, se concentrer sur les implications internationales des politiques tendant à l’unification des systèmes de DPI dans le monde.Le premier chapitre considère une économie fermée. Nous montrons qu’il n’est pas nécessaire que le degré de DPI qui maximise l’utilité pour les travailleurs qualifiés coïncide avec celui des non qualifiés. L’équilibre dans cette économie dépend de sa taille et de la composition du facteur travail. Lorsque le nombre de travailleurs qualifiés est faible par rapport au nombre des travailleurs non qualifiés, une protection totale des DPI bénéficie au travail qualifié en nuisant au travail non qualifié. Ce dernier aurait une utilité supérieure en présence d’une protection plus faible des DPI. Lorsque la taille des deux groupes est similaire, il n’y a plus de conflit d’intérêts : Les deux types de travailleurs préfèrent un régime de DPI qui augmente avec la taille de la population totale.Le deuxième chapitre étend le contenu du premier en incorporant une deuxième économie qui est à la fois plus peuplée et technologiquement supérieure. Le secteur de Recherche et Développement (R&D) domestique bénéficie des connaissances en provenance de l’étranger. Le modèle prédit la convergence du taux de croissance domestique vers le taux de croissance du leader technologique. L’effet positif des DPI est donné par la détermination de « l’écart technologique » entre les deux régions. La protection totale des DPI maximise l’utilité du travail qualifié et, sous certaines configuration des paramètres, du travail non qualifié.Le troisième chapitre introduit le commerce international. Nous considérons deux économies où les travailleurs qualifiés sont hétérogènes en termes de productivité individuelle dans le secteur R&D. Le commerce international requiert le paiement d’un coût fixe pour chaque variété de bien intermédiaire. Il y a deux régions dans le monde : le « Nord » avec une protection totale des DPI, et le « Sud » avec une protection faible. Tout travailleur qualifié dans le secteur R&D fait le choix entre devenir innovateur ou imitateur. Cette modélisation est capable de recréer la domination du Nord dans l’activité d’innovation mondiale, et du Sud dans l’imitation. Un renforcement des DPI dans le Sud se traduit par une redistribution de travailleurs qualifiés hors de l’activité imitative et vers l’innovation. Un nombre plus faible d’imitateurs augmente l’intérêt d’exporter vers le Sud pour les firmes du Nord, ce qui favorise le commerce internationalThis thesis studies the effects of Intellectual Property Rights (IPRs) on the economy. It makes use of a common framework (i.e. an endogenous growth model with horizontal differentiation) to model IPRs, identify the benefits and the costs associated with their implementation, suggest welfare maximizing levels of IPRs in economies with different compositions of the labor force and, finally, focus on the trade aspects of international policies tending to unify IPRs systems in the world.The first chapter considers a closed economy. We find that the utility maximizing degree of IPRs may or not be the same for skilled and unskilled workers. The equilibrium of the economy depends on its size and composition of the labor force. When skilled workers are scarce relative to unskilled workers, complete enforcement of IPRs benefits skilled workers and harm unskilled workers, which prefer a weaker regime. If the two labor endowments are close enough there is no longer a conflict of interests between the two groups. Both prefer a regime of IPRs that increases with the population size.The second chapter extends the first one to incorporate an additional economy which is larger and technologically more advanced. The R&D sector of the small economy benefits from the knowledge developed abroad. The model predicts convergence in the rate of growth to the one of the technological leader. The positive effect of IPRs comes from the determination of the "technological gap" between the two regions. Complete enforcement of IPRs maximizes utility for skilled labor and, under some parameter configurations, also for unskilled labor.The third chapter allows for international trade. We consider two economies where skilled labor is heterogeneous in productivity within the R&D sector. Trade requires the payment of a fixed cost per variety. There are two regions in the world: the South has weaker IPRs and a less skilled labor than the North. Skilled workers in the R&D sector choose between becoming innovators or imitators. This setup recreates the observable patterns of dominance of the North in innovation, and the South in imitation. Stronger IPRs in the South translate into a reallocation of skilled labor out of imitation and into innovation. Less imitators increase the value of exporting to that region for foreign exporters leading to an increase in world trade

In this thesis a model to describe the diffusion of a cluster of inter-related innovations is put forward. Unlike conventional diffusion approaches, which deal with each innovation independently, this model is based on a system of "aggregated measures of diffusion" (AMDs). Such AMDs assume a common technological base and a learning sequence in adoption, and they are derived from a system of double weighting, with scores attached for a) the complexity of each innovation and b) the time-span since adoption. In addition to diffusion measurement, AMDs can be used to assess technological capability of individual firms, industries, regions or countries. In this role they can replace conventional technology measures, particularly when the object of analysis are "traditional industries" or "catching up regions". In the present application, the diffusion of nine innovations available for use in the clothing industry was tracked. Alternative weighting schemes generated different AMDs, successively taken as the dependent variable in a multiple regression exercise. The variables entered into the model matched broadly the conceptual framework, with proxies of technological competence ("qualified technicians" or "intangible investment") and firm size ("sales" or "employment") displaying greater association with the AMDs. Interestingly, the dummy "country" was not selected as significant. This is in line with previous findings in the thesis, which showed an average initial lag between Portuguese and Italian firms of 4 years, narrowing to 2.5 years as diffusion proceeds. These results suggest that the productivity gap (2.6: I) derives mostly from factors other than differences in the adoption of recent hardware. Future policies to narrow this gap could better consider how to improve the handling of existing hardware (training, skills) and other intangible factors (design, quality, marketing and distribution), than concentrating exclusively on fixed capital formation. If these intangible factors are addressed by public policy, it is possible to believe that the Portuguese clothing industry will have an opportunity to survive and prosper. With regard to Italy, there are signs that some of the traditional factors of competitiveness have suffered recently a process of erosion. With the expected phasing out of the MultiFibre Arrangement, Italian tirms must concentrate further in up-market niches and relocate part of their assembling operations to lower cost regions abroad. The possibility of radical technological change reversing dramatically this industry'S pattern of comparative advantage is not a realistic prospect in the short/medium-term. However. the likelihood of full automation in a longer-term remains, and it is possible to expect that those firms which have gone further in adopting certain LT.-related innovations will have a decisive advantage early next century.

Limited transaction and unit attribute information curtail the diffusion potential of green homes and create significant valuation and underwriting problems for the housing debt capital markets, more specifically mortgage originators (lenders) and appraisers. Put into the context of the technology adoption life cycle this missing information prevents green homes from crossing the chasm into the mainstream market. As lenders and appraisers are the gatekeepers of the mainstream mortgage markets, they will be key stakeholders in any strategy for green homes to cross this chasm. The missing transaction and attribute data creates two opportunities for scholarship. The first opportunity is to create and provide preliminary evidence of the chasm in the green housing market place. The second opportunity is to analyze, in the context of this chasm, what information and tools appraisers are using, at present, to estimate the value of high performance homes.Ph. D.

This study aims to explore the position of diffusion oriented support mechanisms in European Community (EC) innovation policy. With the shift from the traditional linear model towards an integrative approach to innovation, the role of diffusion of technologies and knowledge, achieved greater weight. This shift in both the thinking of academic experts, and of national policy makers, induced EC policy makers to appeal for similar changes in Community innovation policy. From the mid-1980s, the Commission of the European Communities, the key actor in EC policy making, thought to move its innovation policy away from the traditional science push approach. This study shows that in the implementation of programmes for research, technology and innovation, the traditional linear model is still dominant. The core research and technological development programmes still operate from a science push concept of innovation, mainly due to their pre-competitive nature. The case of SPRINT illustrates that policy programmes with an integrated innovation perspective can be successful at Community level. However the programme operates in a relatively isolated position from overall research and technological development policy. The case of BRITE-EURAM illustrates the difficulties of collaborative research programmes, the bulk of EC support mechanisms, to move away from the traditional model. The study shows how conflicting policy objectives arising from the different policy networks that shape EC policy making, in combination with a lack of co-ordination in those policy domains, hinder the emergence of the integrated approach. Consequently EC diffusion policy, implemented from the perspective of the linear model, will have a sub-optimal impact on the competitiveness of European industries.

Intensive care delirium prevention is currently a practice improvement goal of the Society of Critical Care Medicine. Delirium increases morbidity, mortality, time mechanically ventilated, length of stay, and health care spending. The Clinical Practice Guidelines for the Management of Pain, Agitation, and Delirium in Adult Patients in the Intensive Care Unit (PAD guidelines) were revised and published in 2013. The ICU Delirium and Cognitive Impairment Study Group at Vanderbilt University have developed the ABCDEF Bundle protocol as a way of operationalizing the 2013 PAD guidelines. Implementation of the ABCDEF Bundle protocol has been shown to decrease occurrence and duration of delirium while improving morbidity and mortality therefore decreasing length of stay. The purpose of this project is to develop an implementation and evaluation plan of the ABCDEF Bundle for a community hospital's TSICU in Arizona. The Squire guidelines for quality improvement reporting are followed for this project. Implementation and evaluation of the ABCDEF bundle are explained in detail.

This study investigates the indicators of the number of ATMs (automated teller machines) in the provinces of Turkey by examining two banks: T.C. Ziraat Bankasi and T. iS Bankasi. The study depends on annual panel data from 1990 to 2004 for seventy-three provinces of Turkey. The information about the number of ATMs of the two banks is gathered after a study in the archives of the banks. In this study it is concluded that the number of ATMs of T. iS Bankasi and T. C. Ziraat Bankasi in the previous year and the total number of branches of the banks in Turkey are the indicators of ATM adoption for both of the banks concerned. However, population has a negative sign for T. C. Ziraat Bankasi which is a state bank whereas it has a positive sign for T. iS Bankasi which is a quasi-private bank. The findings also indicate that the ATM number of T. iS Bankasi is more sensitive to the number of total bank branches.

The goal of this thesis was to study the impact of national culture on the diffusion process of innovation. The study was conducted on consumers in two countries of Sweden and Iran who have significant cultural differences based on Hofstede’s five cultural dimensions model. A questionnaire designed to evaluate the tendency to adopt new products and to imitate was completed by 200 people in each of two respective countries. These participants were well distributed across different genders and age groups. The responses obtained were analyzed to evaluate the impact of culture on adoption of innovation as well as on imitation. In addition, the role of gender on the adoption of new product as well as on imitation was investigated.
The analysis of the data obtained in this study clearly indicates that national culture plays a significant role on the diffusion process of innovation. These results show that the tendency to adopt new products in the Swedish culture is higher than that in the Iranian culture. In other words one can conclude that the tendency to adopt new products in countries with low power distance, low uncertainty avoidance, individualistic, and short term orientation culture is higher than in countries with high power distance, high uncertainty avoidance, collective, and long term orientation culture.
The results of this research also demonstrate that gender also plays an important role in the adoption of new products. These results indicate that the tendency to adopt new product by males in both Sweden and Iran is higher than the tendency to adopt new products by their female counter parts. In other words in both feminine and masculine cultures males have more tendencies to adopt new products than females.

The health industry has acquired a reputation as lagging in the use of information technology (IT). Therefore, this study has been undertaken to assess state health's use of IT and then to assess the causal factors of the differing usage rate, if any. The state health industry was compared to the banking industry as a benchmark, on the basis that the banking industry is widely perceived as a leading IT user. A literature review summarised and critiqued current literature and informed the subsequent research. The research comprised two related studies. The first study was a qualitative study of the beliefs of senior state health executives. The second study was based upon a survey of state health and banking managers. The research confirmed that in these two 'knowledge' industries, state health is slower to adopt IT with an apparent lower maturity level. This finding was observed across a range of best-practice management, procedural and cultural topics as well as the level of resources applied to IT. Innovation-diffusion-theory helped understand why IT implementation has progressed at a slower rate in state health than other industry sectors. The complexity of state health organisations and their fragmented internal structure constrain their ability to adopt traditional, hierarchical, organisation-wide IT. This is further impacted upon by the relative immaturity of clinical health IT, which is complicated, incomplete and unable to show quantifiable benefits. In addition, elements of the findings suggest that health IT departments are poorly aligned to the needs of clinicians and managers. Both organisational and technological factors lead to the slow adoption of health IT, although measures suggest that the key factors relate to the unique organisational nature of state health. The recommendations for health and IT policy arising from this research are: * The effectiveness of state health IT departments needs comparing to those in other sectors and improvement interventions implemented; * The strongest way for state health IT to proceed is to focus on management and social issues in preference to the ever-seductive technology. Research and development funds should be allocated, as a priority, to benefits-analysis methods, improved understanding of the true nature of health organisations (formal and informal) and a rich understanding of clinical behaviours and work. Deeper knowledge in all of these areas will permit the development of more relevant IT leading to greater value, more focussed implementation and new areas for business development in the IT industry.

This thesis takes an interdisciplinary look at wind energy innovation and diffusion through a historical case study and system dynamic quantitative model. The former uses a framework known as actor-network- theory (that allows technical as well social forces to shape historical outcomes) and applies it to an in-depth case study of the history of the technology throughout several époques. Rather than simplifying the story of the technology into a case of winners and losers, as past studies have done, this work demonstrates the complexity of the history of wind technology where many individuals in different countries, companies and national governments, all play a key role in both direct and indirect development of the technology. Without the confluence of activity from these different groups across time and space, the story of wind energy would be very different. In particular, the history shows how the technology develops and diffuses in different regions at different times in different eras, but that traces of each époque survive into the next so that the overall history of wind energy technology has some continuous threads and an accumulation of global learning. This perspective serves as a basis for the development of a system dynamics model of wind energy development and deployment. The model examines the interplay of technology innovation and diffusion dynamics where markets for the technology are local but innovation and learning is global. Wind energy for electricity generation has overcome significant volatility in local markets over the last several decades thanks to the global aggregation of demand from different countries at different times. At the same time, the persistent presence of a market somewhere in the world at any given time has allowed continuous innovation and technology learning to take place. Looking forward, these local and global feedbacks for innovation and diffusion have important implications for the further development of technology and its ability to become a prominent global source of electricity generation.

The Bass model has been used extensively and globally to forecast the first purchases of new products. It has been named by INFORMS as one of the top 10 most influential papers published in the 50-year history of Management Science. Most models for the diffusion of innovation are deeply rooted in the work of Bass (1969). His work provides a framework to model the underlying process of innovation adaption among first-time customers.
Potential customers may be connected to one another in some sort of network. Prior research has shown that the structure of a network affects adoption patterns (Dover et al. 2012; Hill et al. 2006; Katona and Sarvary 2008; Katona et al. 2011; Newman et al. 2006; Shaikh et al. 2010; Van den Bulte and Joshi 2007). One approach to addressing this issue is to incorporate network information into the original Bass model. The focus of this study is to explore how to incorporate network information and other micro-level data into the Bass model.
First, I prove that the Bass Model assumes all potential customers are linked to all other customers. Through simulations of individual adoptions and connections among individuals using a Random Network , I show that the estimate of q in the Bass Model is biased downward in the original Bass model. I find that biases in the Bass Model depend on the structure of the network. I relax the assumption of the fully connected network by proposing a Network-Based Bass model (NBB), which incorporates the network structure into the traditional Bass model. Using the proposed model (NBB), I am able to recover the true parameters.
To test the generalizability and to enhance the applicability of my NBB model, I tested my NBB model on the various network types with sampled data from the population network. I showed that my NBB model is robust across different types of networks, and it is efficient in terms of sample size. With a small fraction of data from the population, it accurately recovered the true parameters. Therefore, the NBB model can be used when we do not have complete network information.
The last essay is the first attempt to incorporate heterogeneous peer influence into the NBB model, based on individuals' preference structures. Besides the significant extension of the NBB (Bass) Model, incorporating high-quality data on individual behavior into the model leads to new findings on individuals' adoption behaviors, and thus expands our knowledge of the diffusion process.

Based on Rogers’diffusion of innovation model, this study examined the effect of innovation attributes and adopters’ characteristics on the adoption of IP-VPN by Taiwan’s small-and-medium-size enterprises. A mail survey with the random sampling method was adopted for data collection and 135 valid questionnaires were obtained. The data analysis shows that innovation attributes were the most powerful variable, according for almost 43% of the variance, and adopters’ characteristics explains less than 1% of the variance. Of the 11 variables, four variables--complexity、compatibility、observability、organization income─were significant predictors. More detailed findings were discussed in the paper.

The diffusion of the Internet is the interest of many firms or individuals who see the Internet as an opportunity, a threat, or both. Huge amount of intellectual and real capital are invested on Internet. The more people understand the dynamics of Internet diffusion, the better they will manage the efforts put on it. The purpose of this study is to explore the extent to which the diffusion of the Internet-related innovation could be adequately described by the diffusion models and the effect of internal influence versus external influence described in the models. Two hypotheses of the Internet innovation diffusion are proposed. First, the number of potential adopters of the Internet innovation diffusion is dynamic, not constant. Second, in contrast to the traditional innovations, the diffusion of Internet innovation has stronger interpersonal communication influence than the promotional activity effect. Twelve Internet innovations are estimated in both the Bass model and the Dynamic model. The first hypothesis is fully supported, and the second hypothesis is partially supported. Based on the evidence, Internet innovations can be categorized into web-based versus non-web. The non-web Internet innovation of connection and communication like Internet, ADSL, and Skype has no significant difference of the ratio of the internal influence and the external influence effects to the traditional innovations. The segment-focused niche website, such as Amazon, eBay, and PayPal, has the strong internal influence effect. Understanding the various effects of Internet innovation diffusion can provide advantages in terms of enhancing functions and planning marketing strategies and tactics.
