Information Systems Security is a relevant factor for present organizations. Among the security measures, policies assume a central role in literature. However, there is a reduced number of empirical studies about the adoption of information systems security policies. This paper contributes to mitigate this flaw by presenting the results of a survey in the adoption of Information System Security Policies in Local Public Administration in Portugal. The results are discussed in light of literature and future works are identified with the aim of enabling the adoption of security policies in Public Administration.

This chapter focuses on design methodologies for pervasive information systems (PIS). It aims to contribute to the efficiency and effectiveness of software development of ubiquitous services/applications supported on pervasive information systems. Pervasive information systems are comprised of conveniently orchestrated embedded or mobile computing devices that offer innovative ways to support existing and new business models. Those systems are characterized as having a potentially large number of interactive heterogeneous embedded/mobile computing devices that collect, process, and communicate information. Also, they are the target of technological innovations. Therefore, changes in requirements or in technology require frequent modifications of software at device and system levels. Software design and evolution for those require suitable approaches that consider such demands and characteristics of pervasive information systems. Model-driven development approaches (which essentially centre the focus of development on models, and involve concepts such as Platform-Independent Models, Platform-Specific Models, model transformations, and use of established standards) currently in research at academic and industrial arenas in the design of large systems...

O objetivo deste estudo é examinar como os Modelos Mentais Compartilhados entre o principal executivo de informática e os demais executivos da alta direção influenciam o alinhamento estratégico de sistemas de informação nas organizações, bem como examinar os fatores que contribuem para a formação de um Modelo Mental Compartilhado. Alinhamento estratégico de sistemas de informação é definido como a congruência entre as estratégias do negócio e de sistemas de informação na organização. Modelo Mental Compartilhado é visto como um constructo multidimensional, composto de uma linguagem comum entre o executivo de informática e os demais executivos da organização e de um entendimento comum sobre o papel de sistemas de informação na organização. A coleta de dados foi feita por meio de uma pesquisa de campo aplicada em organizações atuantes no Brasil. A análise dos dados mostrou que o entendimento compartilhado entre o executivo de informativa e os demais executivos da alta direção sobre o papel de sistemas de informação pode influenciar positivamente o alinhamento estratégico de sistemas de informação nas organizações. Também foi mostrado que a existência de uma linguagem compartilhada entre o executivo de informática e os demais executivos...

The World Bank, together with other donors, has launched a program for promoting information systems in Sub-Saharan Africa. Because of the importance of geo-referenced information systems in resource decision-making, a systematic review of the Bank portfolio in Sub-Saharan Africa has been carried out from Fiscal Year (FY) 1988 to FY 1993. This review assesses if the Bank commitment to developing geo-referenced information systems has been translated into its operation; draws and disseminates lessons; and formulates recommendations. The main findings are as follows: 1) the World Bank commitment to developing geo-referenced information systems is not yet reflected in its operations. 2) Investment in geo-referenced information systems has been concentrated in only a few countries and projects. 3) There are no clear trends in investment over time; but differences appear among Country Departments, some of them focusing more on the development of geo-referenced information systems than others. 4) Land titling...

Automation of government financial management (GFM) systems is one of the core elements of the reform program since ready availability of timely and accurate information is critical to the management of government finances and public funds; and it may simply not be possible to obtain the information required for economic management in a timely manner without some degree of automation, in view of the large transaction volumes involved and their dispersal across multiple sites around the country. These systems are also referred to as integrated financial management information systems (IFMIS). As described in this handbook, IFMIS consists of a number of modules which support the different functional processes associated with GFM. These include modules for macroeconomic forecasting, budget preparation, budget execution (including cash management, accounting, and fiscal reporting), managing the size of the civil service establishment and its payroll and pensions, debt management, tax administration, and auditing. This handbook tries to fulfill the need and to provide information related to the entire systems life cycle...

Downsizing information systems from large and centralized mainframe computing architectures to smaller and distributed desktop systems is one of the most difficult and critical strategic decisions facing both corporate and government organizations. Vendor advertisements and media hype often boast of huge cost savings and greater flexibility while retaining mainframe-strength performance. Cryptic terminology, biased vendor assistance, and rapidly changing technology complicate already difficult decisions. This thesis provides an executive summary for middle and top managers requiring a survey of the major downsizing issues. It provides an overview of architectural trends that are helping to fuel the downsizing process to include an emphasis on the client/ server paradigm, the evolving roles of the mainframe and desktop computers, and innovative architectural software tools. An analysis of management and technical risks according to organizational, performance, and cost factors also focuses on such critical considerations as business process reengineering, open systems, flexibility, throughput, security, conversion costs, and life-cycle costs of downsized systems. Finally, this thesis 'frames' the issues for the Office of Naval Intelligence and DoD by highlighting and outlining some general guidelines that may be used to intelligently plan strategy and make key organizational decisions; http://archive.org/details/downsizinginform00huts; NA; NA; U.S. Navy (U.S.N.) author.

Approved for public release, distribution unlimited; The necessity for well-defined, integrated information systems (IS), driven by today's dwindling human, financial, and management resources, makes it essential to plan effectively. This can only be achieved by linking IS planning to the overall strategic plan of the organization. Department of the Navy (DON) IS planning has historically missed the mark in this report. Information Engineering, automated through Computer Aided Software Engineering (CASE) technology, offers significant benefits for improving DON IS planning. Two CASE workbenches, Information Engineering Systems Corporation's USER: Expert Systems and Texas Instruments' Information Engineering Facility, have proven highly effective in automating IE in DON applications.; Lieutenant, United States Navy Reserve

In recent years, the topics of budget transparency and open data have been increasingly discussed. Most discussants agree that for true transparency, it is important not only that governments publish budget data on websites, but that the data they disclose are meaningful and provide a full picture of their financial activities to the public. Most governments have made substantial investments in capacity building and technology for the development of Financial Management Information Systems (FMIS). This study is the first attempt to explore the effects of FMIS on publishing open budget data, identify potential improvements in budget transparency, and provide some guidance on the effective use of FMIS platforms to publish open budget data. Overall, there are only 48 countries (24 percent) where civil society and citizens have the opportunity to benefit from Public Finance (PF) information published on the web to monitor the budget and hold their governments accountable. In many countries, external audit organizations do not appear to be using the FMIS platforms effectively for monitoring the government's financial activities or auditing the budget results. Governments in high-and middle-income economies publish budget data dynamically in various formats...

Sistemas de Informação de Escritórios são tipos particulares de sistemas de informação. São sistemas sócio-técnicos, muito complexos, com grande influência humana. O tempo tem grande importância no tratamento das informações, tanto na representação de informações temporais explícitas como em restrições de ordem temporal e em características que são alteradas com a evolução da aplicação. Neste trabalho é apresentado um modelo de dados para ser utilizado como método de especificação de requisitos de sistemas de informação de escritórios. 0 desenvolvimento de especificações é uma tarefa bastante complexa, devendo possibilitar a representação de todas as características da aplicação, tanto as estáticas como as comportamentais. A especificação de uma aplicação geralmente é muito extensa, sendo dispendido um tempo considerável em sua elaboração. Um aspecto importante no desenvolvimento de especificações é a verificação da corretude destas, devido a complexidade que apresentam. Uma maneira de gerar especificações mais corretas e em menor espaço de tempo é através da reutilização de especificações anteriormente construídas e já validadas através de implementações. Neste trabalho optou-se por utilizar um modelo de dados orientado a objetos para especificar os sistemas de informação de escritórios. A utilização do paradigma de orientação a objetos na modelagem permite a definição de uma biblioteca de classes de objetos...

Completed research paper; There is a perception that information systems security outsourcing, in spite entailing a relationship between a client and one or more providers, tends to be studied and analysed from the perspective of the client. A gap is then believed to exist in the study of the information systems security outsourcing relationship from the point of view of the service provider. This research aims to identify the key issues of such a relationship from the perspective of the service provider and rank them according to their importance. The Delphi method was used to support the communication with the group of experts contributing to this research as well as to boost consensus within the group. Final interviews with participants were also conducted with the aim of reaching deeper into their opinions and to shed a brighter light over the results of the Delphi. A ranked list of the 13 most important key issues found is presented and discussed and propositions for further work are put forward in the wake of the study.; Fundação para a Ciência e a Tecnologia (FCT)

As the cause of environmental conservation emerges as a global priority, the need for a practical information systems strategy shared among conservation organizations becomes imperative. Historically, researchers and practitioners in conservation have met their own information management and analysis needs with inevitable variation in methodology, semantics, data formats and quality. Consequently, conservation organizations have been unable to systematically assess conditions and set informed priorities at various scales, measure performance of their projects and improve practices through adaptive management. Moreover, the demands on conservation are changing such that the bottom-up approach to information systems will become an increasing constraint to effective environmental problem solving. Where we have historically focused on the protection of “important” places and species and more recently “biodiversity,” conservation is moving to a systems view, specifically ecosystem-based management, where relationships and process are as important as the individual elements. In parallel, awareness of the human dependency on functioning natural systems is on the rise and with it the need to explicitly value ecosystem services and inform tradeoffs. Climate change requires conservation to develop dynamic adaptation scenarios at multiple spatial and temporal scales. Finally...

A função do gestor público municipal passa por uma fase crítica de responsabilidades e cobranças por parte da sociedade. Neste sentido, cabe ao gestor definir metodologias e ferramentas de apoio a decisão, tais como indicadores contábeis, softwares de gestão integrada (ERP) e Sistemas de Informações Gerenciais ou Apoio a Decisão (SIG e SAD), buscando informações gerenciais de maior qualidade e abrangência para que haja um melhor planejamento e uma maior compreensão das atitudes gerenciais e políticas. Este estudo possui como objetivo principal verificar o grau de satisfação do usuário final dos Sistemas de Informação das secretarias de finanças de três grandes municípios do Rio Grande do Sul. A pesquisa demonstrou que, apesar de ser já uma prática constante, não é o simples uso de um sistema de informação que possibilita o funcionamento satisfatório de uma secretaria municipal de finanças. A informatização deve ser seguida de um bom treinamento dos usuários, independente do nível hierárquico, bem como de um eficiente suporte técnico que abasteça e sustente todo processo. Quanto mais ultrapassada a tecnologia utilizada, piores são os índices de satisfação entre os usuários. Os sistemas não-integrados possuem desvantagens consideráveis...

The ability to generate, process and transmit information is the first step of a production process that finishes by its application in the process of value aggregation to products and services. However, in order to provide access to the necessary information for organizations investments in technology are not enough: they must invest in the information infrastructure. In this context, the Information Systems planning should ensure that investments in Information Systems are aligned with the organizational strategy. This article presents the results of the application of the Business System Planning methodology to the Information System planning of the administrative and financial area of the Transit Department of the Alagoas State. The choice of the BSP methodology was motivated by its emphasis on business processes and it provided the identification of the strategic vision of the organization, the business processes of the administrative and financial area and the groups of information necessary to procedures. Additionally, through the use of a prioritization software it was possible to establish groups of information services modules to be developed in a first horizon.; The ability to generate, process and transmit information is the first step of a production process that finishes by its application in the process of value aggregation to products and services. However...

This paper describes (i) how a national health information System was designed, tested and implemented in Papua New Guinea, (ii) how the system was integrated with other management information systems, and (iii) how information has been used to support decision-making. It concludes that central coordination of systems design is essential to make sure that information systems are aligned with government priorities and can deliver the information required by managers. While there is often scope for improving the performance of existing information systems, too much emphasis can be placed on revising data collection procedures and creating the perfect information system. Data analysis, even from imperfect systems, can stimulate greater interest in information, which can improve the quality and completeness of reporting and encourage a more methodical approach to planning and monitoring services. Our experience suggests that senior decision-makers and political leaders can play an important role in creating a culture of information use. By demanding health information, using it to formulate policy, and disseminating it through the channels open to them, they can exert greater influence in negotiations with donors and other government departments...

Efforts to strengthen health information systems in low- and middle-income countries should include forging links with systems in other social and economic sectors. Governments are seeking comprehensive socioeconomic data on the basis of which to implement strategies for poverty reduction and to monitor achievement of the Millennium Development Goals. The health sector is looking to take action on the social factors that determine health outcomes. But there are duplications and inconsistencies between sectors in the collection, reporting, storage and analysis of socioeconomic data. National offices of statistics give higher priority to collection and analysis of economic than to social statistics. The Report of the Commission for Africa has estimated that an additional US$ 60 million a year is needed to improve systems to collect and analyse statistics in Africa. Some donors recognize that such systems have been weakened by numerous international demands for indicators, and have pledged support for national initiatives to strengthen statistical systems, as well as sectoral information systems such as those in health and education. Many governments are working to coordinate information systems to monitor and evaluate poverty reduction strategies. There is therefore an opportunity for the health sector to collaborate with other sectors to lever international resources to rationalize definition and measurement of indicators common to several sectors; streamline the content...
