Esta tese trata do impacto nas Comunicações Internas das Organizações em relação à virtualidade e teve como objetivo descrever e analisar as mudanças ocorridas na comunicação interna das organizações privadas com o advento das tecnologias. Para atingir nosso objetivo fizemos uso da pesquisa bibliográfica, partindo do exame das teorias comunicacionais disponíveis e dos recursos técnicos inerentes à comunicação e às tecnologias da informação aplicadas à organização. Estabelecemos a convergência em relação às tendências e efeitos que poderão ser observados, por meio de um diálogo com especialistas da área Comunicacional através de um estudo qualitativo, onde fizemos uso da metodologia do Painel Delphi com o intuito de descrevermos e analisarmos as mudanças ocorridas nos meios, analisarmos seus impactos e traçarmos um cenário futuro em relação à utilização das tecnologias da informação e comunicação no ambiente organizacional interno. Os resultados de nossa pesquisa demonstraram que a comunicação interna organizacional deverá ser intensamente mediada por computador, mas não se limitará a ele, justamente pela realidade e condição cultural de cada organização, um mix comunicacional (com veículos tradicionais e virtuais) deverá ser a condição mais lógica para uma comunicação eficiente, uma vez que abrange todo o tipo de público e formato de mensagens.(AU)

The thesis presents a two-dimensional Risk Assessment Method (RAM) where the assessment of risk to the groundwater resources incorporates both the quantification of the probability of the occurrence of contaminant source terms, as well as the assessment of the resultant impacts. The approach emphasizes the need for a greater dependency on the potential pollution sources, rather than the traditional approach where assessment is based mainly on the intrinsic geo-hydrologic parameters. The risk is calculated using Monte Carlo simulation methods whereby random pollution events were generated to the same distribution as historically occurring events or a priori potential probability distribution. Integrated mathematical models then simulate contaminant concentrations at the predefined monitoring points within the aquifer. The spatial and temporal distributions of the concentrations were calculated from repeated realisations, and the number of times when a user defined concentration magnitude was exceeded is quantified as a risk. The method was setup by integrating MODFLOW-2000, MT3DMS and a FORTRAN coded risk model, and automated, using a DOS batch processing file. GIS software was employed in producing the input files and for the presentation of the results. The functionalities of the method, as well as its sensitivities to the model grid sizes, contaminant loading rates, length of stress periods, and the historical frequencies of occurrence of pollution events were evaluated using hypothetical scenarios and a case study. Chloride-related pollution sources were compiled and used as indicative potential contaminant sources for the case study. At any active model cell, if a random generated number is less than the probability of pollution occurrence, then the risk model will generate synthetic contaminant source term as an input into the transport model. The results of the applications of the method are presented in the form of tables, graphs and spatial maps. Varying the model grid sizes indicates no significant effects on the simulated groundwater head. The simulated frequency of daily occurrence of pollution incidents is also independent of the model dimensions. However, the simulated total contaminant mass generated within the aquifer, and the associated volumetric numerical error appear to increase with the increasing grid sizes. Also, the migration of contaminant plume advances faster with the coarse grid sizes as compared to the finer grid sizes. The number of daily contaminant source terms generated and consequently the total mass of contaminant within the aquifer increases in a non linear proportion to the increasing frequency of occurrence of pollution events. The risk of pollution from a number of sources all occurring by chance together was evaluated, and quantitatively presented as risk maps. This capability to combine the risk to a groundwater feature from numerous potential sources of pollution proved to be a great asset to the method, and a large benefit over the contemporary risk and vulnerability methods.

The importance of technology to developing countries is widely recognised as they compete internationally and develop internally. Firms acquire technology by different means and from diverse sources, and they possess varying levels of competence. Since countries are at various stages of economic and technological development, prescriptive approaches to technology and operations integration are not appropriate. The paper discusses factors in the literature that affect the integration of technology and operations in developing countries. Country similarities and differences also play a role, so the study examines three developing countries: Brazil, India and South Africa. These countries are emerging from periods of regulation and have developed certain sectors of their economies. Empirical evidence is provided from a study of managers in South Africa who were asked to assess the important factors in technology integration, and to score the extent to which they can control these. Results from the study concur with the literature regarding the importance of a country’s political stability and its policies towards new investment and infrastructure. Knowledge and understanding of technology are essential for successful integration in countries with insufficient skilled personnel, and where education levels are low.

Self-service technology is affecting the service encounter. The potential reduction in personal contact through self-service technology may affect assessments of consumer satisfaction and commitment, making it necessary to investigate self-service technology usage, particularly the long-term impact on consumers' relationships with service organisations. Thus, this paper presents a framework for investigating the impact of self-service technology on consumer satisfaction and on a multi-dimensional measure of consumer commitment. Illustrative quotes from exploratory in-depth interviews support the framework and lead to a set of propositions. Future research directions for testing the framework are also discussed, and potential implications of this research are outlined.

Purpose – The purpose of the paper is to use a case study setting involving the implementation of an enterprise resource planning (ERP) system to expose and analyze the conflicts in the characterizations of the post bureaucratic organisation (PBO) in the literature. ERP implementations are often accompanied by increasing levels of stress in organizations that place pressures on organizational relationships and structures. Additionally, ERPs are regarded as introducing their own techno-logic of centralization, standardization and formalization that provides an apparent contrast to the exhortations about employee empowerment. Design/methodology/approach – A case study of ERP implementation in a medium-sized entity is presented. The paper explores aspects of ERP and PBO from the context of postmodern organization theory. Findings – Some concerns about PBO identified in the literature are reflected in the case situation. For example, there is a commitment to give up private time and work flexibly by some employees. The paper also provides evidence of the way the management team substitute their reliance on a key individual knowledge worker for that of an ERP system and external vendor support. Paradoxically, trust in that same knowledge worker and between core users of the system is essential to enable the implementation of the system. Originality/value – This paper adds empirical insight to a predominantly theoretical literature. The case evidence indicates some conflicting implications in the concurrent adoption of PBO and ERP.

This paper expands research into self-service technology in the service encounter. Self-service technology is where customers deliver service themselves using some form of a technological interface. There is still a great deal unknown about self-service technology, in particular its impact on consumer satisfaction and consumer commitment. With that in mind, this empirical study explores the relative impact of self-service technology on consumer satisfaction and on a multidimensional measure of consumer commitment containing affective commitment, temporal commitment and instrumental commitment. The results reveal that in a hotel context personal service still remains very important for assessments of satisfaction, and affective and temporal commitment. What is particularly interesting is that self-service technology, while impacting these constructs, also impacts instrumental commitment. This suggests that positive evaluations of self-service technology may tie consumers into relationships with hotels. A discussion and implications for managers are provided on these and other results, and the paper is concluded with further potential research.

This paper complements earlier work by the author that shows that the pattern of information arrivals into the UK stock market may explain the behaviour of returns. It is argued that delays or other systematic behaviour in the processing of this information could compound the impact of information arrival patterns. It is found, however, that this does not happen, and so it is the arrival and not the processing of news that is most important. © 2004 Taylor & Francis Ltd.
A note on information seasonality and the disappearance of the weekend effect in the UK stock market
Resumo:
The weekend effect in UK stock prices has disappeared in the 1990s. Beneath the surface however there remain systematic day-of-the-week effects only visible when returns are partitioned by the direction of the market. A systematic pattern of market-wide news arrivals into the UK stock market is discovered and found to provide an explanation for these day-of-the-week effects.

Theory suggests that firms that adopt innovation share some common characteristics, just as those who do not adopt innovation and firms adopt a particular technology because the functions provided by the chosen technology fulfils their needs. Building on these arguments, this research project investigates the antecedents and consequences of e-business adoption among manufacturing firms in Malaysia. This thesis develops from the existing literature of organisational innovation adoption, information technology and strategic marketing/management. It further adds to the existing literature by using cultural-based predictors representing organisational characteristics consisting of market orientation, innovativeness and organisational learning. The study also formalises the theoretical framework of organisational-environment-technology. This study develops a new construct called technology motivation in addition to the introduction of several e-business technology scales. The results substantiate the significance of firm technology motivation in determining firm adoption of the various e-business initiatives. In addition, business environment and market orientation are found to influence firm choice of technology motivation. Meanwhile, innovativeness and organisational learning are shown to influence the magnitude of a firm’s e-business adoption. Finally, the results show that firm adoption of e-business technology does not influence organisational performance. This investigation clarifies the rationale and importance of firm technology motivation in adopting the various e-business initiatives. It also highlights the importance of having the appropriate organisational culture in ensuring a successful technology adoption.

Concern has been expressed in the professional literature - borne out by professional experience and observation - that the supply and demand relationship existing between the 13 English and Welsh Library and Information Studies (LIS) Schools (as providers of `First Professional' staff) and the Higher Education Library and Information Services (HE LIS) sector of England and Wales (as one group of employers of such staff) is unsatisfactory and needs attention. An appropriate methodology to investigate this problem was devised. A basic content analysis of Schools' curricular and recruitment material intended for public consumption was undertaken to establish an overview of the LIS initial professional education system in England and Wales, and to identify and analyse any covert messages imparted to readers. This was followed by a mix of Main Questionnaires and Semi-Structured Interviews with appropriate populations. The investigation revealed some serious areas of dissatisfaction by the HE LIS Chiefs with the role and function of the Schools. Considerable divergence of views emerged on the state of the working relationships between the two sectors and on the Schools' successes in meeting the needs of the HE LIS sector and on CPD provision. There were, however, areas of substantial and consistent agreement between the two sectors. The main implications of the findings were that those areas encompassing divergence of views were worrying and needed addressing by both sides. Possible ways forward included recommendations on improving the image of the profession purveyed by the Schools; the forming of closer and more effective inter-sectoral relationships; recognising fully the importance of `practicum' and increasing and sustaining the network of `practicum' providers.
