Information and communication technologies hope to revolutionize the healthcare industry with innovative and affordable solutions with a focus on pervasive care. Wearable sensors products can provide monitoring in a natural environment with a constant stream of information, enriching healthcare practices and enabling better pervasive care. Wearable sensor technologies could monitor patients' mobility, gait, tremor, daily activity and other health indicators in real time that could allow for simple, non-invasive, tracking of spine care that may lead to increased patient engagement, integration, feedback, post-surgery analysis, monitoring of patient's condition, patient's data extraction and analysis and possibly aiding in better diagnosis, intervention, adherence to treatment for the betterment of quality of care. This research focuses on the assessment of technology adoption potential of medical devices particular to tracking the mobility of patients of neurosurgery and orthopedics. Wearable medical devices that track the mobility of patients after spinal procedures could help surgeons in providing post-operative care, analysis of treatment outcomes and patient mobility. The assessment of those devices by physicians is a complex process associated with various perspectives and criteria. Therefore, the objective of this research is to assess the potential for technology adoption of those wearable medical devices through development of a hierarchical decision-making model (HDM) that incorporates the relevant perspectives and criteria encompassing the needs of hospital neurological surgery and orthopedics departments. The proposed research builds on an existing body of knowledge researched through literature review and background of the field and expands the health technology assessment field by implementation of a holistic, comprehensive and multi-perspective approach to technology assessment in wearable sensor products adoption for pervasive care in neurosurgery and orthopedics. The Hierarchical Decision Model (HDM) approach is used to break the problem down into hierarchical levels and then calculate the alternatives using pairwise comparison scales and a judgment quantification technique. Inconsistencies, disagreement, sensitivity and scenario analysis are performed as well. HDM research software is created with Ruby and R to facilitate the computation of some of these important model parameters to higher precision than is available in current statistical analysis software packages or extensions targeted for decision making. Patient perspective dominates as the main perspective for the technology adoption potential of wearable devices for pervasive care in neurosurgery and orthopedics, followed by technical and financial perspectives. Valedo, a wearable device aimed to relieve back pain through exercises, motivation and mobility tracking, received the highest ranking for adoption potential, while other devices also received high relative scores. The framework could serve as a supplementary technology assessment tool and could be tested in other settings: private, small clinic etc. with the experts and special needs of physicians in particular healthcare departments.

As people age there is an overwhelming desire to remain in the familiar surroundings of the family home, what is called Aging in Place. But inevitable changes that occur in their lives force the aging adults and their families to consider a move to some form of institutional living. Living at a distance from one another, the adult child attempts to maintain peace of mind concerning the well-being of their aging parents but finds it to be a difficult task. I propose to address this problem by first proposing that technology can help minimize the anxieties experienced by the adult child concerning their aging parents well being by appropriately presenting information on the aging parents daily life. This technological design concept does not require that the aging parent input, or for that matter, do anything other than live their lives as they normally live them. Further, this technology provides this information in a manner that is continuously available to the adult child for either opportunistic or planned perusal. As a single instance of the technological design concept proposed above, the Digital Family Portrait embeds well-being related information into an item commonly found in homes, the picture in a picture frame. The Digital Family Portrait was first tested in a wizard-of-oz field trial, then redesigned based on the outcome of this initial field trial coupled with the results of two lab-based studies and a further informal evaluation. The redesigned Digital Family Portrait was built and installed in the home of an adult child while the sensors to drive it were installed in an aging parents home. A field trial of this installation lasting for one year was conducted. The result of this field trial was to find that the Digital Family Portrait was an acceptable means of resolving certain peace of mind issues for the adult child while not raising privacy. It was found to be used in a socially acceptable manner by the adult child while the aging parent to reported feeling less lonely.

In the light of increasing promotion of new information and communications technologies (ICTs) as a tool for economic development, this thesis examines the relationship between ICTs, rural businesses and rural development among rural engineering and manufacturing firms in South Warwickshire and the Cotswolds. Despite high levels of general interest in this subject area, previous research has tended to concentrate on the technical (supply-side) issues of these new technologies; the human (demand-side) aspect has, so far, been largely overlooked. The devised theoretical framework distinguishes between influential factors internal and external to the firm. Empirical research draws upon humanistic behavioural concepts to investigate ICT adoption decision-making processes at the micro-level of individual sectors, enterprises and entrepreneurs in rural areas, and to evaluate the role of external agencies. Firms in the study area are diverse in terms of their ICT adoption and use, and entrepreneurial characteristic and linkages with other businesses and organizations are found to be major determinants of technology requirements and uptake. Two types of firms are identified: inwardly-oriented firms, with local buyer and supplier contacts, which make little use of technology; and outwardly-oriented firms, which use ICTs more intensively and have geographically dispersed networks of customers and suppliers. While notable levels of general awareness of ICTs exist among rural businesses, the initial financial outlay involved, coupled with a lack of knowledge of existing technological solutions and support, and a need for skills training, remain significant disincentives to ICT uptake among smaller firms. Agencies currently lag behind local businesses in terms of their ICT awareness and use, and understanding of the potential development implications of technology. In many cases there is a mis-match between agencies' perceptions of ICT use in rural firms and their response to this area of business support. Although there is a recognition amongst agencies that their client firms are applying new technologies in their business processes, ICTs are seen by the majority of agencies as a future component of business strategy. Thus, appropriate support for firms implementing ICTs is not yet widely accessible. Findings suggest that ICT implementation is not appropriate in all firms; requirements and applications vary widely and there is a need for a tailored approach by agencies and policy makers which takes account of the uniqueness of entrepreneur and firm characteristics.

O tema inovação vem sendo cada vez mais difundido e disseminado globalmente, o que por um lado é benéfico quanto à sua popularização e desmistificação, por outro lado corre o risco de se tornar uma referência retórica e superficial. Diante desse cenário, várias definições surgem e o conceito de inovação ultrapassa a barreira puramente tecnológica de produtos e processos para agregar questões de marketing e organizacionais. Contudo, os órgãos de fomento à inovação ainda sentem dificuldade na identificação do que é ou não inovação. Isso se dá pela falta de processos estruturados de análise que possibilitem maior segurança na avaliação de projetos ou propostas que envolvam oportunidades de inovação. Nesse contexto, o presente trabalho tem como principal objetivo propor um processo de análise para apoiar à caracterização de uma potencial inovação, identificando se ela é uma oportunidade de inovação e de que tipo.Trata-se de uma pesquisa aplicada de caráter exploratório. Como método foi utilizado a pesquisa bibliográfica e de campo, como técnica a testagem com 15 especialistas no tema, com abordagem prioritariamente qualitativa.

On this given scenario, several definitions arise and the innovation concept goes beyond the purely technological barrier products and processes to aggregate marketing and some others organizational aspects. However, innovation promotion agencies still have issues on identify what is or is not innovation. That can be explained due to the lack of structured processes of analysis that enable safer proposals or projects evaluation involving innovation opportunities. On that context, the present work has as main objective to propose an analysis process to give support to a potential innovation characterization, identifying whether it is an innovation opportunity and at which typology it mainly fits. This is an applied and exploratory research. The used method was literature research and field testing as a technique with 15 experts on the subject, with primarily qualitative approach. Among the main results can be cited the analysis proposal process to sustain the innovation characterization and distinction of its typology, comprising three analysis blocks; and the contribution to define the innovation type in frontier areas. However, there was still identified a convergence difficulties, even among experts, for some cases evaluated, which opens an opportunity for further research on the topic. These cases are also described on this present work.

Thesis (MBA)--Stellenbosch University, 2014. / ENGLISH ABSTRACT: The telecommunications industry generates vast amounts of data on a daily basis. The exponential growth in this industry has, therefore, increased the amounts of nodes that generates data on a near real-time basis, and the required processing power to process all this information has increased as well. Organisations in different industries have experienced the same growth in information processing, and, in recent years, professionals in the Information Systems (IS) industry have started referring to these challenges as the concept of Big Data (BD). This theoretical research investigated the definition of big data as defined by several leading players in the industry. The theoretical research further focussed on several key areas relating to the big data era: i) Common attributes of big data. ii) How do organisations respond to big data? iii) What are the opportunities that big data provide to organisations? A selecting of case studies are presented to determine what other players in the IS industry does to exploit big data opportunities. The study signified that the concept of big data has emerged due to IT infrastructure struggling to cope with the increased volumes, variety and velocity of data being generated and that organisations are finding it difficult to incorporate the results from new and advanced mining and analytical techniques into their operations in order to extract the maximum value from their data. The study further found that big data impacts each component of the modern day computer based information system and the exploration of several practical cases further highlighted how different organisations have addressed this big data phenomenon in their IS environment. Using all this information, the study investigated the 4C Group business model and identified some key opportunities for this IT vendor in the big data era. As the 4C Group has positioned themselves across the ICT value chain, big data presents several good opportunities to explore in all components of the IS. While training and consulting can establish the 4C Group as a big data knowledgeable vendor, some enhancements to their application software functionalities can provide additional big data opportunities. And as true big data value only originates from the utilization of the data in the daily decision making processes, by offering IaaS the 4C Group can enable their clients to achieve the illusive goal of becoming a data driven organisation.

This study employs duality theory to model the dairy industry. Supply and demands for milk, cull cows, feed, labor and veterinary services were simultaneously estimated using Weighted Least Squares. Elasticities and partial adjustments were obtained for the Nation and the following regions, Appalachia, Cornbelt, Northeast, Pacific, Southern Plains and Upper-Midwest. Predictions for the change in quantity of goods demanded and supplied were made assuming a parallel shift in the supply of milk and demand for feed. In conclusion, predictions on the impact of bovine Somatotropin are made assuming all results are correct.

With the unprecedented growth of the communication industry that the world is experiencing, the demand from rural inhabitants for high quality communications at an economically affordable cost is growing. However, rural areas are rather restricted from deploying communication services due to the rough natural environment, and the shortage of rudimentary communication facilities and technical personnel. Appropriate models for building rural wireless networks and a concomitant simulation environment are, therefore, expected to enable the construction of technologically-optimal and economically-efficient networks in specified rural areas.<br /> <br /> The research has set up two independent models, one for the economic need and the other for the technical need of building networks in rural areas. One model was the Impact of Telecommunications Model, which disclosed the importance of building a wireless network in specified rural areas by choosing an economic parameter to forecast the profitability of the network. The other was the Service Model, which collected primitive data from given rural areas and abstracted these data by flowing them through four technical layers to form the predicted technical wireless network. Both of the models had been applied to real-world cases to demonstrate how to use them.<br /> <br /> A simulation environment was finally designed and implemented to realize the above two models for the sake of instantiation. This environment could simulate the specified rural network by constructing a wireless network on the invented areas and evaluating its quality and economic efficiency. It was written in Scilab simulation language, which was an open source.

The Machinery Question during the early Nineteenth Century was the question of the impact of technical progress on the total economy and society. The question was central to everyday relations between, master and workman, but it was also of major theoretical and ideological interest. The very technology at the basis of economy and society was a fundamental platform of challenge and struggle. In the early Nineteenth Century, it was political economy, the 'natural science' of economy and society which took up the theoretical debate on the introduction, diffusion, and social impact of the radically new techniques of production associated with the era. The machine question also came to infuse not only the theoretical realm of political economy, but also the wider culture and consciousness of the bourgeoisie and the working classes. The machine question reflected the close connections of the relations of production to the concerns and conflicts pervading theory, culture and politics. This thesis has analyzed only one part of this many sided issue. It has focused on the attempt of the middle classes to use the new science of political economy to depict technical progress as a natural and evolutionary phenomenon. However, the thesis also shows that the great variety of theoretical traditions in political economy, combined with significant theoretical and working class dissent with the so called doctrine of political economy prevented the unqualified success of this attempt. The depth of the controversy evoked over the machinery issue indicated the still marked uncertainty of the experience of industrialization. By the 1820's and 1830's the factory, urban agglomerations and the coal heaps of mining counties had transformed some parts of the industrial landscape. But the permanence of this change still seemed questionable. Such change was still confined to a very small number of regions, affected small sections of the population, and contributed minimally to national income. The experience of technical change was of great novelty and excitement for those who contemplated the prospects of wealth and power it might bring. On the other hand, for the first generation of factory labour and cast off artisans and domestic workers, it still seemed possible to stop the 'unnatural' progress of technology. Working men and women felt keenly the unprecedented demands for mobility, both geographical and occupational. For them the machine meant, or at least threatened, unemployment, an unemployment which at best was transitional between and within sectors of the economy, and at worst affected the economy as a whole at times of scarce capital. For them the machine was accompanied by a change in the pattern of skills, and involved all too often the introduction of cheap and unskilled labour. In the period before the 1840's, when labour's great onslaught was against the machine itself, the machine question also featured in middle class doctrine. The times were still uncertain enough to demand that the 'cult of improvement' take on the shape of a cultural offensive rather than mere complacency. Thus the 'cult of improvement' during this era sought its -reatest scientific context in political economy. Most of the secondary literature on this period depicts the views of the middle classes and especially of political economy as ones of great pessimism. This thesis shows, to the contrary, that optimism and great faith in the new industrial technology was fundamental to the vision of political economy and to that of its middle class adherents. Ricardo's work was an intellectual and doctrinal tour de force which gripped the whole period, but which, in addition, just as significantly generated a great array of criticism. Curiously, the great historical problem of Ricardo's work was the lack of understanding it met, and the serious distortion it suffered at the hands of his popularizers. The great range of Ricardo criticism in the decades after his death was based often on misconceptions of his work. His own Principles which exuded so much interest in and hope for technical progress generated a wealth of dissident literature which also focused on improvement, skill and technical change. Though the political economy of these years was very diverse, and policy debates were hotly conducted, there is no doubt that the self-defined profession of political economy accepted certain assumptions and outlooks. There were several themes and conceptions which shaped the overall nature of this critique of Ricardo. These themes allow for the demarcation of two epochs of political economy between the 1820's and the 1830's. Political economists of the 1820's placed great emphasis on labour productivity and the skills of the artisan in their attempt to contradict the so called Ricardic predictions of overpopulation and the stationary state. By the 1830's economists still found in 'improvement,' technical change, and increasing returns, the great empirical and theoretical rebuttal to the 'Ricardian' predictions. However, 'improvement' was now discussed as the evolution of capital, and even more crucial to this change was the tendency to see capital as a material embodiment, as fixed capital and machinery. This shift of concepts was accompanied by a new methodological thrust. The political economy of the 1830's reflected a polemically inductivist mood. Unprecedented energy was devoted to debates over abstraction and induction. The political economy which resulted was more empirical, comparative and historical. New interest was given over to visiting factory districts, drawing on government reports, and in using and participating in social surveys. Political economists devoted more time to comparing the course of economic development in Britain to that of other Western economies, that of primitive societies, and that of previous historical epochs. The conceptual shift in political economy over these years seems to parallel certain tendencies and changes in the economy itself. The political economy of the 1820's appears to reflect the concerns underlying the economic-phase defined by Marx as the phase of 'manufactures'. The shift that takes place in theory in the 1830's approximates to the shift in the economy to the phase of 'modern industry.' But the conceptual changes in political economy over the period are also very closely connected to class struggle. This shows in the very seriousness attached by political economists to the 1826 anti-machinery riots in Lancashire and to the 1830 agricultural riots. Discussion of these two disturbances infused the very heights of economic theory. The establishment of political economy reflected the alarm of the middle classes and provided the 'scientific' answers to the working man's critique of machinery. Moreover, in debate with their critics, they helped to generate a new theory of technical change based on the machine and on the evolution and security of capital and the capitalist. The overall effect of these riotc on the middle clashes was a celebration of the cult of technical improvement. The force of this 'scientific' optimism in political economy was given a deep cultural basis in middle class improvement societiesandmdash;the Mechanics Institute Movement of the 1820's and the scientific and statistical societies of the 1830's. These movements were attempts to involve both the working classes and the middle classes in a concerted energetic programme to promote technical advance. They also acted to forge new cultural connections between the provinces and the metropolis. A scientific movement which, in its rhetoric at least, focused on the practical, economic and technological connections of science, created a new nexus simultaneously economic and cultural between province and metropolis. This scientific culture was material and empirical.
