Technological progress and technology acquisition : models with and without rivalryRahman, Atiqur. January 1999 (has links)
In a technology driven world, technology acquisition decisions as to when and which new technologies to acquire are becoming increasingly critical for firms to survive and grow. The issue of technology acquisition is addressed with three different focuses in the current dissertation. / In the first essay, we extend the results of some existing literature. Existing literature suggests that, in an oligopoly, identical firms acquire the same technology at two different dates under Nash or pre-commitment equilibrium, which assumes infinite information lag between two firms. The set of equilibrium dates turn out to be different under subgame perfect or pre-emption equilibrium that assumes zero information lag. We show that allowance for asymmetry between firms leads to the same equilibrium dates under Nash and subgame perfect equilibrium. / In the second essay, a two-period technology game is considered to study the effect of expectations regarding technological progress on a firm's technology adoption decision in a duopoly. It is shown that expectations of better future technology retard adoption of the currently available technology. Uncertain future progress is shown to have either no effect or negative effect on the adoption of the currently available technology when a Nash or open-loop equilibrium holds. However, under subgame perfection, uncertainty may actually encourage adoption of the current technology, contrary to what literature suggests. / In the third essay, a stochastic mathematical programming framework is used to build a decision model to solve for technology decisions facing rapid and uncertain technological progress. In our scenario-based approach, we allow uncertainties in both technological developments as well as in output product market demands. Furthermore, the acquisition costs of the technologies are assumed to be concave to reflect economies of scale in acquisition. An efficient procedure to solve the problem is proposed and implemented. Our numerical results show that the expectation of future technologies impacts the acquisition of the current technology in a negative way, and highlights the importance of incorporating expectations in a technology acquisition model.

Integrating Internet-facilitated international academic partnerships into local university environments : faculty perspectivesPalvetzian, Talene E. January 2005 (has links)
This study explores how to integrate faculty-initiated Internet-facilitated international academic partnerships into their local university environments. Recently some faculty have begun initiating international partnership activities which carryout their university's research, teaching, and service missions. These partnerships (including courses, projects, or entire programs) are considered by their initiators to benefit both faculty and student development. Faculty see the Internet as enabling them to construct interactive and collaborative virtual forums where disperse student and faculty bodies can co-engage in exciting international research, teaching, and learning opportunities. This study aims to encourage the development of Internet-facilitated international academic partnerships so that more faculty in all disciplines are supported by their local institutions to better integrate their partnerships. Presently, partnerships are not well integrated. Impart this is because the Internet as a communication tool is relatively new phenomenon. However, it is also due to the tendency for faculty level partnerships to be overlooked by higher levels of university administration. As a result, the value of Internet partnerships has not yet been explored in relation to their local institutional missions. This study therefore consults faculty with experience partnering online in order to garner faculty insights pertaining to partnership integration. The results help to determine (1) core characteristics of these faculty-level partnerships (2) faculty motivations for initiating them (3) university environments implicated by integration and (4) identify faculty support and development opportunities appropriate to support integration.

A critical reflection on teaching and learning music in the context of technological change /Lukianenko, Sofia. January 1998 (has links)
This essay explores the benefits and limits of teaching and learning music in a changing technological environment, where both students and instructors are faced with the perpetual problem of keeping up with new methods of practicing music for the purpose of maintaining competence. The essay critically reflects on the argument that present societies overvalue technical instruments, at times giving consumers a false hope of achieving quick results in a brief period of time, and with the unintended consequence that playing techniques can be compromised. The idealizing of mechanical devices has become strongly associated today with sophisticated taste and class. Following Mumford and Postman, the essay argues that these technological tools should be seen as posing a challenge to instructional values and to human agency. This essay concludes that while we cannot help the fact that tradition is constantly being renewed, in part through technological change, the role of teaching that learning music needs to be focused on are historic values which incorporate experience and reciprocity.

Influence of copyright on the emergence of new technologies : a North American perspectiveDeschamps-Marquis, Marie Hélène. January 1999 (has links)
This thesis studies the impact of North American copyright on technological development. The first section proposes a broad vision of copyright including both Canadian and American legal concepts. It analyses different modern definitions of copyright, the origin of the concept and its underlying justifications. The second section presents the historical relations between copyright and technologies. It studies the history of the printing press, the photography, the player-piano, the motion picture, the radio, the cable TV, the photocopier, the videotape, the Digital Audio Tape and the MP3, and the legal challenge they represented. Those elements give us the opportunity to evaluate the influence of copyright on technological development.

Elderly adults' perceptions of home lifestyle monitoring technologyBooker, Cortlan G. 06 August 2011 (has links)
The following is a qualitative study designed to collect and study elderly (>65) perceptions of in home lifestyle monitoring technology. Data were collected through three focus groups, organized and analyzed for results. The focus groups were run in a semi-structured manner with the co-moderators presenting questions from an original valid instrument. The study suggests that nearly all of the participants are comfortable with current technologies and around 50% of the sample group would be interested in using the new proposed technologies. The study also suggests that the participants have a high level of current wellness and are generally comfortable in their current residence. / Fisher Institute for Wellness and Gerontology

Communication aided architects : the information age and the architectural professionGilles, Werner January 1999 (has links)
The fundamental question in design communication is how closely the architect's intention matches what the viewer perceives in the proposed design representation. The goal of this thesis is to find more efficient means to facilitate understanding of design ideas, especially between the architect and the client or other lay-people.In the following sections this will be accomplished by investigating the history of various communication modes and evaluating their significance. The development of communication technology throughout recent centuries has contributed to changes in the architectural process. After assessing the current situation of applying communication technology in the architectural process, the thesis concludes with a scenario. The scenario will describe a futuristic architectural process, which eliminates misunderstanding in design presentations by using the next level of communication technology - immersive computer generated spaces. / Department of Architecture

Microeconomic foundations of knowledge-driven growth : modelling the dynamic allocation of R&D resourcesGoddard, John Gabriel January 2004 (has links)
This D.Phil, thesis undertakes a theoretical analysis of the microeconomic incentives for scientific and technical knowledge-creating activities at the firm-level, the channels by which these activities impinge on industrial change and economic growth, and the effectiveness of governmental policies formulated to influence these systemic linkages. The motivation for this work is explained in Chapter 2, which reviews the state of the art in new growth theory and puts forward a typology of privately sponsored RandD activities and knowledge resources defining the premises on which the thesis rests. Chapters 3 and 4 investigate the RandD allocation and output decisions of a profitmaximising monopolist investing in exploratory- and applications-oriented research, dealing separately with product and process innovations. The characteristic properties of the optimal time paths are ascertained by means of formal and numerical optimal control methods, including comparative dynamics. The complementarity between the two modes of research is shown to generate increasing returns, but these turn out to be short-lived. The model is extended in Chapter 5 to study the development of multiple product lines. Knowledge spillovers and demand-side externalities across successive product lines can provide the basis for continued spending on RandD, allowing sustained output growth and profitability. Chapters 6 to 8 turn to the challenges of modelling the irreducible elements of uncertainty in the innovation process and their bearing upon the dynamics of market competition and industry structure. In the sequential game theoretic model introduced, firms can invest in fundamentally uncertain "innovative-RandD," or wait until the uncertainty surrounding original innovation is dispelled and invest in certain but costly "imitative-RandD." These decisions are taken in a vertically and horizontally differentiated market where noninnovating firms can compete with a "traditional" product. The industry-wide scale of RandD investments and the related evolution in market structure are determined endogenously. To do so, a symmetric equilibrium concept is defined and its uniqueness established. The model can support Schumpeterian industry evolutions, in which surges of innovative entry are followed by waves of imitation, and ensuing "creative destruction" in which traditional producers are driven out of the industry and innovators' rents are eventually eroded. Numerical simulations are employed in Chapter 7 to provide further insights into the evolution of product development, market structure, pricing, firm growth, profitability, and consumer welfare. The final chapter considers the implications of this game theoretic approach for competition and innovation policies.

Technological change and growth dynamics : an analysis of UK industriesMeacci, Mara January 2003 (has links)
In this work we investigate the sources and growth effects of technological innovation in UK industries over the years 1966-1993. Our main finding is that technological activities are always beneficial to labour productivity growth and normally also beneficial to employment growth. Moreover, it is possible to aggregate industries into fairly stable technological clusters, and the main sources of innovation change broadly in accordance with the technological characterisation of the industry. We also analyse the effect of inter-industry demand transmissions on employment share dynamics, and find that these effects are generally important. However, demand expansions in customer industries do not always imply expanding employment shares in supplying industries, and we did not find any evident linkage between the sign of the demand effect and the technological characterisation of industries. Testing the models developed to fit observed changes in labour productivity and employment shares over the periods 1974-79 and 1979-91, we find that growth dynamics over the period 1974-79 have been more related to technological change than over the period 1979-91. In particular, pure capital deepening has been one of the main engines of growth over the period 1979-91.

The technological economics of glass recyclingMatthews, Rolf Benjamin January 1986 (has links)
This thesis examines the technological economics of glass recycling in Britain. Attention was focused on recovery schemes operated within Scotland, comparisons being made with schemes in the rest of Britain and in Europe. An examination was made of general recycling problems and of glass recycling problems in particular. The various systems for glass recycling were reviewed and were put in the context of the waste management system as a whole. A survey was undertaken of Local Authorities operating glass recycling schemes. The aim was to provide a comprehensive data set to enable a consistent assessment of glass recovery schemes to be taken. This emphasised the importance of taking a standard approach to assessing the viability of recovery schemes. This needs to be done in terms of both private and social costs and benefits to provide a full economic assessment of the system. A general computer model has been developed to allow local authorities to check the viability of their on-going operations. As they operate under different conditions this model was split into separate assessment of a Bottle Bank scheme and a trade collection scheme. In addition, an investment appraisal model was developed to cover both situations. These allow managers to assess the viability of their schemes and can be used to highlight key costs. An International review was undertaken to see what lessons may be learned and what actions may be taken by the local authorities, industry, the general public, and by central government.
