    Get PDF
    Business process re-engineering (BPR) has come to recognize a need for the adoption of socio-technical methodologies and capabilities for knowledge representation of qualitative concerns. Security planning and decision-making has a similar need, and furthermore socio-technical methods common to BPR can be usefully applied in this capacity. The introduction of security models like Defense-in- Depth and similar efforts to recognize the organizational impact of security planning in operational security management serve as an initial step in educating security personnel and provide a more comprehensive view, but unfortunately, security decision-making has traditionally relied almost solely upon quantitative risk assessment, cost/benefit mechanisms, and related, functionalistic methodologies. This greatly limits the representational capacity of the decision process, and with it the possible dimensions of analysis in which to consider security issues. Within this paper, we briefly examine security planning and the relevant techniques of BPR and Socio-technical design, and present a framework for their integration within the context of information security. It is our contention that such methodologies can be utilized in the security decision process to facilitate representation of subjective concerns and broadly-defined issues germane to security policy, within an organizational context

    This report is part of the Fire Island Prison Feasibility Study, a project conducted jointly by the School of Justice and School of Engineering at University of Alaska, Anchorage under contract to the Alaska Department of Corrections. The project undertook to assess the feasibility of locating a correctional facility on a 4,240 acre tract of land on Fire Island, which lies in Upper Cook Inlet about three miles off Point Campbell within the Municipality of Anchorage. The project was divided into three major phases: (1) an assessment of future bed space needs of the Alaska Department of Corrections; (2) an evaluation of the physical site and cost estimates for prison construction and operation; and (3) a public opinion survey and open discussion.The growth of the Alaska prison inmate population over the past fifteen years has been substantial. According to available statistics there were 482 institutionalized adult prisoners under control of the Alaska Division of Corrections in January 1971; by January 1980 this population had increased to 770 inmates; and between 1980 and 1985, the number of Alaska inmates almost tripled, rising from 770 to 2,073. Accurate forecasts of the future size and makeup of the prison population are needed as a basis for long-range programs and capital planning. This report presents long and short-term forecasts of the Alaska incarcerated prisoner population and bedspace needs of the Alaska Department of Corrections through the year 2000. The forecasts were developed by taking into consideration historical facts and status quo assumptions. Attention is also given to the impact of the 1980 Alaska criminal code revision on unsentenced and sentenced populations. The forecast derived from this study provides evidence of the need for additional institutional capacity in Southcentral Alaska by 1990. Planning should proceed for a capacity of 1,000 beds to be available for use by 1990.Alaska Department of CorrectionsAcknowledgments / Summary of Study / I. Introduction / II.

    Power System Operation Planning Considering Dynamic Line Rating Uncertainty

    The restructuring of power systems and wider introduction of renewable energy sources in the recent years is placing a greater stress on the transmission system. Yet, transmission system is paramount for the reliable, secure and economic operation of power systems. However, modern transmission systems often have insufficient capacity, leading to bottlenecks, congestions and spillage of renewable energy, while their expansion is generally expensive, complicated and time consuming. As an alternative to the transmission expansion, dynamic line rating technologies allows to utilize latent capacity of transmission lines through the use of measurements or forecasts of weather parameters. However, as the forecasts of the weather parameters are inherently uncertain, the estimates of transmission capacity also become uncertain, and must be addressed accordingly. This thesis investigates the impacts of dynamic line rating forecast uncertainty in power system operational planning problems. Thus, the thesis aims at developing mathematical models for the management of such uncertainty to ensure secure and effective operation of power systems. In order to achieve the above objective, firstly, stochastic models for the dynamic line rating are developed that allow to consider thermal dynamics of the conductor in the presence of uncertain weather forecasts. The models are entirely data-based and provide a risk-averse method of controlling conductor temperature in operational planning problems. Furthermore, the models allow to control both the probability of occurrence and the magnitude of the thermal overloading. Secondly, an analysis of uncertain factors and their interactions in power system operational planning is performed using the coherent risk measure framework. Additionally, a novel modelling approach for the uncertain renewable energy sources in operational planning problems is proposed. Then, coherent reformulations of uncertain constraints are developed and integrated into day-ahead unit commitment problem. Finally, the benefits of managing risk in operational planning problems using coherent risk measures are demonstrated in comprehensive case studies

    Strengthening Integrated Primary Health Care in Sofala, Mozambique

    Background: Large increases in health sector investment and policies favoring upgrading and expanding the public sector health network have prioritized maternal and child health in Mozambique and, over the past decade, Mozambique has achieved substantial improvements in maternal and child health indicators. Over this same period, the government of Mozambique has continued to decentralize the management of public sector resources to the district level, including in the health sector, with the aim of bringing decision-making and resources closer to service beneficiaries. Weak district level management capacity has hindered the decentralization process, and building this capacity is an important link to ensure that resources translate to improved service delivery and further improvements in population health. A consortium of the Ministry of Health, Health Alliance International, Eduardo Mondlane University, and the University of Washington are implementing a health systems strengthening model in Sofala Province, central Mozambique.Description of implementation: The Mozambique Population Health Implementation and Training (PHIT) Partnership focuses on improving the quality of routine data and its use through appropriate tools to facilitate decision making by health system managers; strengthening management and planning capacity and funding district health plans; and building capacity for operations research to guide system-strengthening efforts. This seven-year effort covers all 13 districts and 146 health facilities in Sofala Province.Evaluation design: A quasi-experimental controlled time-series design will be used to assess the overall impact of the partnership strategy on under-5 mortality by examining changes in mortality pre- and post-implementation in Sofala Province compared with neighboring Manica Province. The evaluation will compare a broad range of input, process, output, and outcome variables to strengthen the plausibility that the partnership strategy led to healthsystem improvements and subsequent population health impact.Discussion: The Mozambique PHIT Partnership expects to provide evidence on the effect of efforts to improvedata quality coupled with the introduction of tools, training, and supervision to improve evidence-based decision making. This contribution to the knowledge base on what works to enhance health systems is highly replicable for rapid scale-up to other provinces in Mozambique, as well as other sub-Saharan African countries with limitedresources and a commitment to comprehensive primary health care

    Network Modeling of Hurricane Evacuation Using Data-Driven Demand and Incident-Induced Capacity Loss Models

    The development of a hurricane evacuation simulation model is a crucial task in emergency management and planning. Two major issues affect the reliability of an evacuation model: one is estimations of evacuation traffic based on socioeconomic characteristics, and the other is capacity change and its influence on evacuation outcome due to traffic incidents in the context of hurricanes. Both issues can impact the effectiveness of emergency planning in terms of evacuation order issuance, and evacuation route planning. The proposed research aims to investigate the demand and supply modeling in the context of hurricane evacuations. This methodology created three scenarios for the New York City (NYC) metropolitan area, including one base and two evacuation scenarios with different levels of traffic demand and capacity uncertainty. Observed volume data prior to Hurricane Sandy is collected to model the response curve of the model, and the empirical incident data under actual evacuation conditions are analyzed and modeled. Then, the modeled incidents are incorporated into the planning model modified for evacuation. Simulation results are sampled and compared with observed sensor-based travel times as well as O-D-based trip times of NYC taxi data. The results show that the introduction of incident frequency and duration models can significantly improve the performance of the evacuation model. The results of this approach imply the importance of traffic incident consideration for hurricane evacuation simulation

    The introduction of Concurrent Engineering highlights the need for a link between the early stages of product design and assembly planning. This thesis presents aggregate assembly process planning as a novel methodology to provide this link. The theory behind the research is to bring all aspects of product development together to consider assembly planning at the conceptual stage of design. Decisions taken during the early design stage not only have the greatest influence on production times and costs, but also should ensure that a design is easy to manufacture and assemble. An automated computer-based system has been developed to implement the methodology. The system generates aggregate assembly process plans which give details of feasible sequences, assembly process times and costs, resource requirements, and factory loadings. The Aggregate Assembly Modelling and Planning (AAMP) system employs object-oriented modelling techniques to represent designs, process planning knowledge, and assembly resources. The minimum information requirements have been identified, and a product model encompassing this data has been developed. An innovative factor of this thesis is to employ Assembly Feature Connections (AFCs) within the product model to represent assembly connectivity. Detailed generic assembly process models, functioning with limited design data, are used to calculate assembly criteria. The introduction of a detailed resource model to represent assembly facilities enables the system to calculate accurate assembly times, dependent on which resources are used within a factory, or even which factory is employed. A new algorithm uses the structure of the product model, process constraints and assembly rules to efficiently generate accurate assembly sequences. Another new algorithm loads the assembly operations onto workstations, ensuring that the capability and capacity are available. The aggregate assembly process planning functionality has been tested using products from industry, and has yielded accurate results that prove to be both technically feasible and realistic. Industrial response has been extremely favourable. Specific comments on the usefulness and simplicity of such a comprehensive system gives encouragement to the concept that aggregate assembly process planning provides the required link between the early stages of product design and assembly planning

    Building capacity to develop an African teaching platform on health workforce development: a collaborative initiative of universities from four sub Saharan countries

    Get PDF
    INTRODUCTION: Health systems in many low-income countries remain fragile, and the record of human resource planning and management in Ministries of Health very uneven. Public health training institutions face the dual challenge of building human resources capacity in ministries and health services while alleviating and improving their own capacity constraints. This paper reports on an initiative aimed at addressing this dual challenge through the development and implementation of a joint Masters in Public Health (MPH) programme with a focus on health workforce development by four academic institutions from East and Southern Africa and the building of a joint teaching platform. METHODS: Data were obtained through interviews and group discussions with stakeholders, direct and participant observations, and reviews of publications and project documents. Data were analysed using thematic analysis. CASE DESCRIPTION: The institutions developed and collaboratively implemented a ‘Masters Degree programme with a focus on health workforce development’. It was geared towards strengthening the leadership capacity of Health ministries to develop expertise in health human resources (HRH) planning and management, and simultaneously build capacity of faculty in curriculum development and innovative educational practices to teach health workforce development. The initiative was configured to facilitate sharing of experience and resources. DISCUSSION: The implementation of this initiative has been complex, straddling multiple and changing contexts, actors and agendas. Some of these are common to postgraduate programmes with working learners, while others are unique to this particular partnership, such as weak institutional capacity to champion and embed new programmes and approaches to teaching. CONCLUSIONS: The partnership, despite significant inherent challenges, has potential for providing real opportunities for building the field and community of practice, and strengthening the staff and organizational capacity of participant institutions. Key learning points of the paper are: *the need for long-term strategies and engagement; *the need for more investment and attention to developing the capacity of academic institutions; *the need to invest specifically in educational/teaching expertise for innovative approaches to teaching and capacity development more broadly; and *the importance of increasing access and support for students who are working adults in public health institutions throughout Africa.Web of Scienc

    Focus of this paper are success factors for the implementation of an E-Government strategy. Whileconcepts for a sophisticated strategy process in Public Sector are delivered on a regular basis, the gapbetween ambitious planning and its implementation seems to get wider. Authors seek to define whatmakes a “good strategy” in order to enhance management capacity. Meanwhile some scholars fromPolitical Science see limitation of Governments on announcements which are not followed up bysufficient action rather as systematic problems, challenging concept and rules of liberal westerndemocracy, or owed to growing complexity of Governance under the conditions of globalization. Incontext of the introduction of New Public Management and its perception of citizens as customers andon the basis of new available technical options in Information Society, a key Governance reform projectin European and other Countries over the last fifteen years has been the introduction of E-Government.European market leader in this field is Austria. The author reviews concept and implementationexperiences of the Austrian E-Government strategy, analyzes key success factors and opens adiscussion, under which conditions a successful implementation of E-Government can take place inIndonesia
