Inserida de maneira central na atualidade está a questão da difusão da tecnologia de informação (TI) em todos os níveis da sociedade. Governos em todo o mundo têm se preocupado com a inclusão de seus países na ?economia digital? e investido na construção de infra-estruturas tecnológicas que permitam conectar suas instituições, cidadãos e empresas entre si e com o mercado global. Isso se reflete em um intenso processo de informatização da sociedade, e, especialmente no caso das empresas, se faz necessário para que possam participar deste mercado. Apesar disso, muitos estudos apontam dois aspectos que destoam desse quadro: em primeiro lugar, não se comprovou relação direta entre investimentos realizados em TI e a obtenção de resultados como o aumento da lucratividade ou produtividade empresariais; e, em segundo lugar, muitas empresas, especialmente de micro, pequeno e médio porte encontram-se em posição relativamente atrasada nesse processo. Quanto ao primeiro aspecto, o que tem despontado como principal conclusão dos estudos é o fato de que não importa o quanto se investe em tecnologia, mas sim o como essa tecnologia é utilizada para o efetivo apoio aos processos empresariais. Em relação ao segundo aspecto...

A presente pesquisa analisa as percepções de diretores de escola sobre o processo de incorporação das Tecnologias da Informação e Comunicação (TIC) em seu trabalho. Focamos o diretor de escola como o organizador do trabalho da escola. Desta forma, as TICs devem estar inseridas na gestão da escola, para que haja unicidade de objetivos educativos com as TICs e não somente um trabalho de práticas isoladas de professores. O levantamento bibliográfico realizado abrange as áreas da Administração Escolar e da Tecnologia Educacional. A partir da síntese de assuntos correlatos das duas áreas de estudo foi possível elaborar um instrumento de coleta de dados: uma escala Likert. Esta escala, construída à partir das dimensões de trabalho do diretor de escola ?pedagógico, administrativo e político, objetiva analisar os fatores significativos do trabalho do diretor de escola usando as TICs. A escala foi aplicada nos alunos, diretores de escola da rede estadual paulista de ensino, do curso de Especialização em Gestão Educacional (CEGE) entre os meses de janeiro a março de 2007. Os dados obtidos foram analisados de forma quantitativa, segundo a Análise Fatorial Exploratória. Identificou-se 13 fatores que são significativos para o uso das TICs na escola e no trabalho do diretor...

Information technology governance is a process by which organizations align their information technology operations and services with their performance goals and strategic objectives and assess the results. The financial sector has benefited greatly from the development of information technology, primarily in bank automation. There are few research works aimed at describing information technology governance, and there are even fewer in the financial sector. This paper is aimed at measuring information technology governance in financial institutions using the methodology proposed by Weill and Ross (2004). The sample consisted of sixty professionals from financial institutions operating in Brazil. The average performance score was approximately 79.6, showing that the organizations studied have not achieved maximum performance (100), although many are very close to it. This paper describes an original empirical study of Brazilian financial institutions concerning information technology management performance. The survey investigates not only the context of performance, but also the importance that the organization places on each item related to information technology governance aligned with business needs and goals.

The growing availability of continuous data from medical devices in diabetes management makes it crucial to define novel information technology architectures for efficient data storage, data transmission, and data visualization. The new paradigm of care demands the sharing of information in interoperable systems as the only way to support patient care in a continuum of care scenario. The technological platforms should support all the services required by the actors involved in the care process, located in different scenarios and managing diverse information for different purposes. This article presents basic criteria for defining flexible and adaptive architectures that are capable of interoperating with external systems, and integrating medical devices and decision support tools to extract all the relevant knowledge to support diabetes care.

We would like to propose two critical dimensions for strategy: "Industry Scope Shift" and "Reverse Strategy Trace." Recent changes in the progress of information technology and economic globalization raised the importance of these dimensions. Rapid progress in information technology requires firms to respond to the changes of scope including market and product. The execution speed is increasingly becoming critical to keep uniqueness of product and service offerings. Industry Scope Shift helps the capturing of these changes into strategy. Economic globalization demands the organizational challenge to manage conflicts between local market responsiveness and global operation efficiency. Reverse Strategy Trace gives a clear perspective to analyze emergent strategy to accumulate organizational learning from business operations. We will examine the importance of these two dimensions and provides answers when and why these are critical in the strategy planning process.; by Yasuhiko Kiuchi.; Thesis (S.M.M.O.T.)--Massachusetts Institute of Technology, Sloan School of Management, Management of Technology Program, 2004.; Includes bibliographical references (leaves 80-83).

Databases and analysis tools currently being used to study carbon dioxide capture and storage (CCS) options are managed by diverse organizations and are heterogeneous in format. Tools to study the various components of a CCS system have been developed in several fields including chemistry, geology, and economics. Data being used to run analyses are being obtained from an equally diverse set of organizations, from data collected for environmental assessments to data on oil and gas exploration. These variations in tools and data cause complications in systems-level analyses, resulting in additional effort expended in data collection and opportunities for human error. A geographic information system has been implemented to automate and support robust studies of both component and system options. Context management and information integration techniques have been designed into the system. The system improves the availability and quality of information by automatically managing the distributed and heterogeneous data sources. The resulting information is being used to advance research and development of CCS systems through efforts such as the NETL sponsored Regional Carbon Sequestration Partnerships. This paper will present an overview of the system and initial results of its application to CCS-related data.; by David Su-Kai Cheng.; Thesis (S.M.)--Massachusetts Institute of Technology...

Drivers using information from an Advanced Traveler Information System (ATIS) could potentially make better travel decisions to reduce travel time and increase trip reliability, thereby benefiting both guided drivers as well as those without such access. However, market penetration of ATIS can have dramatic effects on the performance of the transportation system in terms of overall benefits conferred as well as the distributional effects between guided and unguided drivers. Because market penetration will be determined both by private market structure and public policies, the effective deployment of ATIS depends critically on the private and public organizations that will provide these services. An understanding of the relationship between transportation system performance and ATIS market penetration provides important insights into a sustaining market structure for the ATIS industry. This thesis provides an empirical study of the impact of ATIS on transportation network quality of service using an application of DynaMIT (Dynamic network assignment for the Management of Information to Travelers). An analysis of the simulation results serves to inform the public and private stakeholder positions in the creation of a better market for ATIS. The main results are that the provision of dynamic route guidance can simultaneously benefit the individual performance of drivers...

This thesis explores one tool of government action - information - and its influence on local policy and planning. This thesis is not a comprehensive account of information-based strategies, which would require far-reaching analysis. Instead, this thesis explores designation as one example of an information-based strategy that is used in planning and development. Specifically, this thesis explores how the act of designating an area as a national historic site ("designation") can, if at all, influence local policy and planning and, subsequently, shapes our built environment. Using the Blackstone River Valley National Heritage Corridor as a case study, I demonstrate that information strategies such as designation can provide a vital and dynamic planning tool for government. Designation presents a new approach to preservation and development by encouraging dynamic, cross-boundary partnerships that are simultaneously committed to common goals and dynamic enough to respond to the complexities of place. Designation allows local communities to maintain a place-specific approach to planning, while operating within a larger regional network. In the case of the Blackstone River Valley National Heritage Corridor, designation united twenty-four communities across a bi-state region between Massachusetts and Rhode Island. Designation in this region cultivated a coherent and dynamic vision that...

There are various kinds of clinical documents used in a hospital or clinic setting. With the emergence of Electronic Medical Records, efforts are being made to computerize these documents in a structured fashion in order to enable decision support. With structured data entry, because each fact about the patient is stored discretely and can be retrieved separately, information can be organized and presented in different ways, depending on the needs of the user. A typical structured clinical document contains a range of findings recorded by a physician, nurse or other care. These findings can be thought of as discrete pieces of information, called observations. These observations can be grouped together to form observation sets that can be placed under relevant headers within the document. When building information systems that support structured clinical documentation, these observations and sets are created and stored in catalogs. My thesis addresses the issue of building an ontology model for clinical documentation that supports the creation and management of an observations catalog, observation sets catalog and a clinical document catalog. The ontology can be used as an organizational tool for efficient maintenance of these catalogs. By tagging observations and observation sets with relevant attributes...

The amount of electronically accessible information has been growing exponentially. How to effectively use this information has become a significant challenge. A post 9/11 study indicated that the deficiency of semantic interoperability technology hindered the ability to integrate information from disparate sources in a meaningful and timely fashion to allow for preventive precautions. Meanwhile, organizations that provided useful services by combining and reusing information from publicly accessible sources have been legally challenged. The Database Directive has been introduced in the European Union and six legislative proposals have been made in the U.S. to provide legal protection for non-copyrightable database contents, but the Directive and the proposals have differing and sometimes conflicting scope and strength, which creates legal uncertainty for valued-added data reuse practices. The need for clearer data reuse policy will become more acute as information integration technology improves to make integration much easier. This Thesis takes an interdisciplinary approach to addressing both the technology and the policy challenges, identified above, in the effective use and reuse of information from disparate sources.; (cont.) The technology component builds upon the existing Context Interchange (COIN) framework for large-scale semantic interoperability. We focus on the problem of temporal semantic heterogeneity where data sources and receivers make time-varying assumptions about data semantics. A collection of time-varying assumptions are called a temporal context. We extend the existing COIN representation formalism to explicitly represent temporal contexts...

Sales of services are becoming a major source of revenues across industries. The shift towards services has been exacerbated as human capital has gained in importance in the "knowledge economy." And yet, products businesses have historically attracted, and are still attracting, most of the attention of managers and scholars. Centering on the information technology services industry, this thesis analyzes the strategy, structure, and performance of services firms. We analyze the information technology services industry and propose a framework to determine the drivers of performance of information technology services firms. The framework is applied to a database of 831 information technology services firms from 1990 to 2004. Chapter II provides an insight into the dynamics of the information technology industry. Chapter III then focuses on the specificities, characteristics and structure of the information technology services firms. In Chapter IV, the business model of services firms is contrasted with that of products firms. Inter-relations between the two business models are proposed. Chapter V introduces a strategic management framework and applies it to the definition of drivers of performance of IT services firms, which are analyzed in Chapter VI...

The healthcare industry is expanding swiftly and total healthcare expenditures are expected to reach 18% of GDP by 2008. However there exist steep variances in quality of care and high incidences of medical error. This has given impetus to efforts at progressively evolving the healthcare delivery system. The role of information technology (IT) is seen as being central to cost reduction and quality improvement of healthcare delivery. Furthermore, efficiency gains will realize approximately 20% in cost reductions. However, there are significant challenges associated with widespread adoption of IT by healthcare providers. Despite the existence of vendor and technology maturity, implementation rates for clinical patient record systems were only 35% in 2006. This study addresses the problem of low IT adoption in hospitals through a three pronged analysis methodology. A Clockspeed analysis has revealed a dichotomy between the maturity levels of technology and vendors on the one hand and delivery processes on the other. This has resulted in lower business value being realized from IT investments by healthcare providers.; (cont.) To address the concern of low business value realization from IT investments, a workflow and Social Networking Analysis was conducted on the surgery patient flow process of a prominent Boston area hospital. It was demonstrated that productivity gains could be achieved through redesign of social networks at the workplace and by inculcating an enterprise-wide process orientation. This would generate greater business value from existing IT investments and thereby impact the rate of IT adoption. Furthermore...

Improvement in efficiency of healthcare in the United States is an urgent issue. Information technology is seen as one of key solutions to improve efficiency. As such, hospitals in the United States are rapidly adopting information technology. However, past studies on information technology development projects in other industries have documented a very high rate of failure, typically attributable to the lack of treatment of organizational and behavioral factors. These studies placed their focus on the development phase of information technology projects but very few studied the performance of installed information systems and factors affecting their performance. In our study, we developed an analytical framework to measure the performance of an existing information system and to identify determinants of its performance based on the Performance of Routine Information System Management Framework by MEASURE Evaluation Project, United States Agency for International Development. Performance is defined as the quality of data and the use of information an information system generates. Technical, behavioral, and organizational factors are considered as determinants of Performance.; (cont.) We evaluated the performance of an information system which records operating room delays and their causes at a large teaching hospital in Boston...

Since the introduction of computers and the Internet, information processing has evolved to be a major part of many businesses, but factors that contribute to the productivity of information workers are still understudied. Some social network studies claim that diverse information that passes through workers in the positions with diverse sources of information drives performance. However, such claims are rarely verified by empirical data. This study develops a measurement methodology for the diversity of the email content processed by information workers. The diversity values will be used for future productivity studies along with the results from social network analysis.

Although most people agree that the use of information technology increases workplace productivity, the exact relationship between productivity and different characteristics of information employees send and receive, such as entropy, information rate and mutual information is not very well studied. By using empirical data, this study develops methodologies to measure the entropy, information rate and mutual information of the email content exchanged between information workers. Furthermore, the validity of these methodologies is evaluated using comparable, publicly available datasets. The evaluation shows that important informational characteristics of email messages, namely the entropy values, are preserved even when messages undergo transformations that preserve privacy and anonymity.; by Meshkat Farrokhzadi.; Thesis (M.

High-throughput molecular data are revolutionizing biology by providing massive amounts of information about gene expression and regulation. Such information is applicable both to furthering our understanding of fundamental biology and to developing new diagnostic and treatment approaches for diseases. However, novel mathematical methods are needed for extracting biological knowledge from high-dimensional, complex and noisy data sources. In this thesis, I develop and apply three novel computational approaches for this task. The common theme of these approaches is that they seek to discover meaningful groups of genes, which confer robustness to noise and compress complex information into interpretable models. I first present the GRAM algorithm, which fuses information from genome-wide expression and in vivo transcription factor-DNA binding data to discover regulatory networks of gene modules. I use the GRAM algorithm to discover regulatory networks in Saccharomyces cerevisiae, including rich media, rapamycin, and cell-cycle module networks. I use functional annotation databases, independent biological experiments and DNA-motif information to validate the discovered networks, and to show that they yield new biological insights. Second...

This thesis identifies the specific characteristics of information aggregators, and proposes nine business models appropriate for information aggregators. These nine models are: advertising, brokerage, subscription, licensing, infomediary (information intermediaries), referral/click-through, customized/personalized service, professional service/consulting, and application service provider. The thesis then looks into various companies who base their businesses on information aggregation and analyzes the development of their business models in the context of competition. The financial and social performances of these companies are studied and reasons are explored. In the end, the thesis summarizes findings from case studies, lists the widely used business models and the rarely used ones, and explores reasons for this phenomenon. The conclusion of this research is that information aggregation is a start point for a company to develop differentiated product or services. Companies can develop into an independent information aggregators; they can use information aggregation as a platform; they can partner with aggregatees or customers to provide customized information. Eventually, many will be integrated into end-to-end solutions, or penetrate into traditional businesses by leveraging information aggregation. The research can be used by companies who develop information aggregation products or services. It can also be used to evaluate the viability of information aggregation initiatives.; by Jiangxia Hu.; Thesis (S.M.)--Massachusetts Institute of Technology...

This dissertation recounts the development of graphic models of human bodies and virtual reality simulators for teaching anatomy and surgery to medical students, residents, and physicians. It considers how researchers from disciplinary cultures in medicine, engineering, and computer programming come together to build these technologies, bringing with them values and assumptions about bodies from each of their disciplines, values and assumptions that must be negotiated and that often are made material and embedded in these new technologies. It discusses how the technological objects being created privilege the body as a dynamic and interactive system, in contrast to the description and taxonomic body of traditional anatomy and medicine. It describes the ways that these technologies create new sensory means of knowing bodies. And it discusses the larger cultural values that these technologies reify or challenge. The methodology of this dissertation is ethnography. I consider in-depth one laboratory at a major medical school, as well as other laboratories and researchers in the field of virtual medicine. I study actors in the emerging field of virtual medicine as they work in laboratories, at conferences, and in collaborations with one another. I consider the social formations that are developing with this new discipline. Methods include participant observation of laboratory activities...
