    The main goal of the chapter is the presentation of the application project portfolio management approach to support development of e-Municipality and public administration information systems. The models of how people publish and utilize information on the web have been transformed continually. Instead of simply viewing on static web pages, users publish their own content through blogs and photo- and video-sharing slides. Analysed in this chapter, ICT (Information Communication Technology) projects for municipalities cover the mixture of the static web pages, e-Government information systems, and Wikis. So, for the management of the ICT projects' mixtures the portfolio project management approach is proposed.

    Full Text Available One of the primary assumptions in many project portfolio selection is the availability of all parameters. However, in real-world cases, many parameters are under uncertainty and the exact values are unknown in advance. This paper presents a scenario based mathematical model for project portfolio selection when parameters are under uncertainty. The problem considers two objective functions where the first one maximizes the net present value while the second objective function is the minimization of the positive deviations from the allocation of resources. The second objective function is looking for project resource leveling. The resulted model is formulated as mixed integer programming and the problem is analyzed under different conditions.

    Pedro Bruno de Souza

    2015-01-01

    Full Text Available Although much has been written about how to manage individual projects, there is still little guidance on how to evaluate the “quality” of project portfolio management itself, that is, the degree of “accomplishment” of the process by which the project portfolio is formed and run. This study addresses this gap by employing a q ualitative approach to uncover managerial perceptions about what is encompassed by project portfolio management and how the this construct should be evaluated. By building from a review of the scant literature on project portfolio management , conversations with expert scholars on project management, interpretations provided by managers, and theoretical reflection by the authors of this study, it was possible to identify main aspects that seem to tap how the degree of “accomplishment” of project portfolio ma nagement can be conceptually defined and operationally measured.

  3. Successful healthcare programs and projects: organization portfolio management essentials.

    Science.gov (United States)

    Pickens, Scott; Solak, Jamie

    2005-01-01

    Many healthcare organization projects take more time and resources than planned and fail to deliver desired business outcomes. Healthcare IT is a major component of many projects and often undeservedly receives the blame for failure. Poor results are often not a result of faulty healthcare IT or poor project management or poor project execution alone. Many projects fail because of poor portfolio management--poor planning and management of the portfolio of initiatives designed to meet an organization's strategic goals. Because resources are limited, portfolio management enables organizations to more strategically allocate and manage their resources so care delivery, service delivery, and initiatives that advance organizations toward their strategic goals, including healthcare IT initiatives, can be accomplished at the levels of quality and service desired by an organization. Proper portfolio management is the essential foundation for program and project success and supports overall organization success. Without portfolio management, even programs and projects that execute flawlessly may not meet desired objectives. This article discusses the essential requirements for porfolio management. These include opportunity identification, return on investment (ROI) forecast, project prioritization, capacity planning (inclusive of human, financial, capital, and facilities resources), work scheduling, program and project management and execution, and project performance and value assessment. Portfolio management is essential to successful healthcare project execution. Theories are drawn from the Organizational Project Management Maturity Model (OPM3) work of the Project Management Institute and other leading strategy, planning, and organization change management research institutes.

    ENGLISH ABSTRACT: In many organisations, a chasm exists between the development of strategy and its successful implementation. Failure to cross this chasm may ultimately result in strategy failure and the loss of competitive advantage, profits, and employment. Project Portfolio Management (PPM is theorised as a management methodology that links a portfolio of projects to the business strategy. However, current literature lacks empirical evidence of the levels of employment, functionality, and success of the Project Portfolio Management approach in South Africa. A survey of respondents in 32 technology organisations was used to analyze the reasons for the following: strategy implementation and project delivery failure in South African technology organisations; the South African situation regarding the chasm that exists in many organisations between strategy development and successful strategy implementation; and the extent to which – and with what success – Project Portfolio Management is employed in South African technology organisations.

    AFRIKAANSE OPSOMMING: In baie organisasies bestaan daar ’n gaping tussen strategie-ontwikkeling en suksesvolle strategie-implementering. Die onvermoë om die gaping te oorbrug sal uiteindelik lei tot strategiefaling en die verlies van mededingende voordeel, winste, en werksgeleenthede. Projekportefeuljebestuur (PPB word voorgehou as ’n bestuursmetodologie wat ’n portefeulje van projekte koppel aan die besigheidstrategie.

    2017-01-01

    Full Text Available The Russian business community has realized the need for project/targeted programme management procedures; therefore, the demand for customized project-oriented management methods goes up. In the meantime, this demand is not supplied in full, and the supply is far from being efficient. Project management methodologies need further improvement, including development of portfolio management processes applicable to investment projects developed and implemented in the construction industry. The article considers General approaches to the formalization of the management of portfolios of investment–construction projects. For the main groups of processes portfolio management (“Formation and alignment”, “Monitoring and control” and “Support and development” deals with their constituent sub-processes. The proposed decomposition can be used for both portfolio construction and investment projects and also has an invariant character, which allows extending the proposed approaches to other system target–oriented and project–oriented management.

  6. A portfolio evaluation framework for air transportation improvement projects

    Science.gov (United States)

    Baik, Hyeoncheol

    This thesis explores the application of portfolio theory to the Air Transportation System (ATS) improvement. The ATS relies on complexly related resources and different stakeholder groups. Moreover, demand for air travel is significantly increasing relative to capacity of air transportation. In this environment, improving the ATS is challenging. Many projects, which are defined as technologies or initiatives, for improvement have been proposed and some have been demonstrated in practice. However, there is no clear understanding of how well these projects work in different conditions nor of how they interact with each other or with existing systems. These limitations make it difficult to develop good project combinations, or portfolios that maximize improvement. To help address this gap, a framework for identifying good portfolios is proposed. The framework can be applied to individual projects or portfolios of projects. Projects or portfolios are evaluated using four different groups of factors (effectiveness, time-to-implement, scope of applicability, and stakeholder impacts). Portfolios are also evaluated in terms of interaction-determining factors (prerequisites, co-requisites, limiting factors, and amplifying factors) because, while a given project might work well in isolation, interdependencies between projects or with existing systems could result in lower overall performance in combination. Ways to communicate a portfolio to decision makers are also introduced. The framework is unique because (1) it allows using a variety of available data, and (2) it covers diverse benefit metrics. For demonstrating the framework, an application to ground delay management projects serves as a case study. The portfolio evaluation approach introduced in this thesis can aid decision makers and researchers at universities and aviation agencies such as Federal Aviation Administration (FAA), National Aeronautics and Space Administration (NASA), and Department of Defense (DoD), in

  10. A Metaheuristic Approach for IT Projects Portfolio Optimization

    CERN Document Server

    Pushkar, Shashank; Mishra, Akhileshwar

    2010-01-01

    Optimal selection of interdependent IT Projects for implementation in multi periods has been challenging in the framework of real option valuation. This paper presents a mathematical optimization model for multi-stage portfolio of IT projects. The model optimizes the value of the portfolio within a given budgetary and sequencing constraints for each period. These sequencing constraints are due to time wise interdependencies among projects. A Metaheuristic approach is well suited for solving this kind of a problem definition and in this paper a genetic algorithm model has been proposed for the solution. This optimization model and solution approach can help IT managers taking optimal funding decision for projects prioritization in multiple sequential periods. The model also gives flexibility to the managers to generate alternative portfolio by changing the maximum and minimum number of projects to be implemented in each sequential period.

    Full Text Available The aim of this article was to assess the use of a group-based project for an empirical finance type of course. It examines the outline of the project, the methodology the students are encouraged to follow and how the course is assessed. This approach enables the students to apply many of the techniques learnt on this course and other courses such as econometrics, to determine an optimal portfolio of assets given their view on the risks in the economy. The emphasis is on risk management through portfolio diversification and the use of a simple hedge strategy. The overall aim was to introduce the students to the basics of portfolio management, as many work in this industry for their industrial placements and when they graduate. The main contribution to the literature is through the analysis of an empirically based portfolio management project. The feedback from the students suggests they felt that they had learnt useful concepts and information, in an enjoyable exercise.

    Full Text Available Adequately managing project interdependencies among diverse and simultaneous projects is deemed critical for successful implementation of project portfolios. The challenge is significant because it may entail managing a complex network of project interdependencies that keeps changing over time. The present study investigates the managerial challenges that may undermine effective management of project interdependencies in IT/IS project portfolios. The investigation is based on evidence from reviewing relevant literature and documented studies associated with managing project interdependencies. The main contribution of this study is to discuss three managerial challenges of project interdependencies in project portfolios. We discuss the challenges from three perspectives: types of interdependencies; patterns of interaction in interdependencies; and cost/benefit impact of project interdependencies.

  14. A Multiagent Evolutionary Algorithm for the Resource-Constrained Project Portfolio Selection and Scheduling Problem

    Directory of Open Access Journals (Sweden)

    Yongyi Shou

    2014-01-01

    Full Text Available A multiagent evolutionary algorithm is proposed to solve the resource-constrained project portfolio selection and scheduling problem. The proposed algorithm has a dual level structure. In the upper level a set of agents make decisions to select appropriate project portfolios. Each agent selects its project portfolio independently. The neighborhood competition operator and self-learning operator are designed to improve the agent’s energy, that is, the portfolio profit. In the lower level the selected projects are scheduled simultaneously and completion times are computed to estimate the expected portfolio profit. A priority rule-based heuristic is used by each agent to solve the multiproject scheduling problem. A set of instances were generated systematically from the widely used Patterson set. Computational experiments confirmed that the proposed evolutionary algorithm is effective for the resource-constrained project portfolio selection and scheduling problem.

  17. Developing a took for project contingency estimation in a large portfolio of construction projects

    Directory of Open Access Journals (Sweden)

    Van Niekerk, Mariette

    2014-11-01

    Full Text Available To enable the management of project-related risk on a portfolio level in an owner organisation, project contingency estimation should be performed consistently and objectively. This article discusses the development of a contingency estimation tool for a large portfolio that contains similar construction projects. The purpose of developing this tool is to decrease the influence of subjectivity on contingency estimation methods throughout the project life cycle, thereby enabling consistent reflection on project risk at the portfolio level. Our research contribution is the delivery of a hybrid tool that incorporates both neural network modelling of systemic risks and expected value analysis of project-specific risks. The neural network is trained using historical project data, supported by data obtained from interviews with project managers. Expected value analysis is achieved in a risk register format employing a binomial distribution to estimate the number of risks expected. By following this approach, the contingency estimation tool can be used without expert knowledge of project risk management. In addition, this approach can provide contingency cost and duration output on a project level, and it contains both systemic and project-specific risks in a single tool.

  1. A Hybrid Grey Based KOHONEN Model and Biogeography-Based Optimization for Project Portfolio Selection

    Directory of Open Access Journals (Sweden)

    Farshad Faezy Razi

    2014-01-01

    Full Text Available The problem of selection and the best option are the main subject of operation research science in decision-making theory. Selection is a process that scrutinizes and investigates several quantitative and qualitative, and most often incompatible, factors. One of the most fundamental management issues in multicriteria selection literature is the multicriteria adoption of the projects portfolio. In such decision-making condition, manager is seeking for the best combination to build up a portfolio among the existing projects. In the present paper, KOHONEN algorithm was first employed to build up a portfolio of the projects. Next, each portfolio was evaluated using grey relational analysis (GRA and then scheduled risk of the project was predicted using Mamdani fuzzy inference method. Finally, the multiobjective biogeography-based optimization algorithm was utilized for drawing risk and rank Pareto analysis. A case study is used concurrently to show the efficiency of the proposed model.

  2. Application and project portfolio valuation using enterprise architecture and business requirements modelling

    Science.gov (United States)

    Quartel, Dick; Steen, Maarten W. A.; Lankhorst, Marc M.

    2012-05-01

    This article describes an architecture-based approach to IT valuation. This approach offers organisations an instrument to valuate their application and project portfolios and to make well-balanced decisions about IT investments. The value of a software application is assessed in terms of its contribution to a selection of business goals. Based on such assessments, the value of different applications can be compared, and requirements for innovation, development, maintenance and phasing out can be identified. IT projects are proposed to realise the requirements. The value of each project is assessed in terms of the value it adds to one or more applications. This value can be obtained by relating the 'as-is' application portfolio to the 'to-be' portfolio that is being proposed by the project portfolio. In this way, projects can be ranked according to their added value, given a certain selection of business goals. The approach uses ArchiMate to model the relationship between software applications, business processes, services and products. In addition, two language extensions are used to model the relationship of these elements to business goals and requirements and to projects and project portfolios. The approach is illustrated using the portfolio method of Bedell and has been implemented in BiZZdesign Architect.

  7. Learning through a portfolio of carbon capture and storage demonstration projects

    Reiner, David M.

    2016-01-01

    Carbon dioxide capture and storage (CCS) technology is considered by many to be an essential route to meet climate mitigation targets in the power and industrial sectors. Deploying CCS technologies globally will first require a portfolio of large-scale demonstration projects. These first projects should assist learning by diversity, learning by replication, de-risking the technologies and developing viable business models. From 2005 to 2009, optimism about the pace of CCS rollout led to mutually independent efforts in the European Union, North America and Australia to assemble portfolios of projects. Since 2009, only a few of these many project proposals remain viable, but the initial rationales for demonstration have not been revisited in the face of changing circumstances. Here I argue that learning is now both more difficult and more important given the slow pace of deployment. Developing a more coordinated global portfolio will facilitate learning across projects and may determine whether CCS ever emerges from the demonstration phase.

  8. New Method of Selecting Efficient Project Portfolios in the Presence of Hybrid Uncertainty

    Directory of Open Access Journals (Sweden)

    Bogdan Rębiasz

    2016-01-01

    Full Text Available A new methods of selecting efficient project portfolios in the presence of hybrid uncertainty has been presented. Pareto optimal solutions have been defined by an algorithm for generating project portfolios. The method presented allows us to select efficient project portfolios taking into account statistical and economic dependencies between projects when some of the parameters used in the calculation of effectiveness can be expressed in the form of an interactive possibility distribution and some in the form of a probability distribution. The procedure for processing such hybrid data combines stochastic simulation with nonlinear programming. The interaction between data are modeled by correlation matrices and the interval regression. Economic dependences are taken into account by the equations balancing the production capacity of the company. The practical example presented indicates that an interaction between projects has a significant impact on the results of calculations. (original abstract

  9. A Hybrid Grey Relational Analysis and Nondominated Sorting Genetic Algorithm-II for Project Portfolio Selection

    Directory of Open Access Journals (Sweden)

    Farshad Faezy Razi

    2014-01-01

    Full Text Available Project selection and formation of an optimal portfolio of selected projects are among the main challenges of project management. For this purpose, several factors and indicators are simultaneously examined considering the terms and conditions of the decision problem. Obviously, both qualitative and quantitative factors may influence the formation of a portfolio of projects. In this study, the projects were first ranked using grey relational analysis to form an optimal portfolio of projects and to create an expert system for the final project selection. Because of the fuzzy nature of the environmental risk of each project, the environmental risk was predicted and analyzed using the fuzzy inference system and failure mode and effect analysis based on fuzzy rules. Then, the rank and risk of each project were optimized using a two-objective zero-one mathematical programming model considering the practical constraints of the decision problem through the nondominated sorting genetic algorithm-II (NSGA-II. A case study was used to discuss the practical methodology for selecting a portfolio of projects.

    2014-03-01

    Full Text Available Purpose. To identify the ways of perspective development for railway transport one should solve the problem of forming the investment project portfolio. Thus, it is necessary to deal with uncertainty in the input data (prices of services, materials, energy products. To take into account this uncertainty it is proposed to use the developed model of stochastic programming. Methodology. For accounting of uncertain data the probabilistic limits on the quantities of resources, which are used in the project portfolio are imposed. As the objective function it is proposed to maximize the threshold, which with a given probability may exceed the planning interval of the net income. Findings. Stochastic programming model with line-by-line probabilistic constraints was obtained. Coefficients of this model are normally distributed random variables. Ratios, which allow calculating mathematical expectations and covariance matrices of these coefficients, were concluded. Originality. Known methods of forming the optimal project portfolio are based on the fact that all inputs are known exactly. On the basis of this consideration, the authors of works on the creating an optimal project portfolio have come to a scheme of deterministic mathematical programming. In this article we propose to take into account the uncertainty in the input data, which will increase the reliability of the portfolio effectiveness estimation through the use of stochastic mathematical programming scheme. Practical value. The developed model can be used in order to solve the planning problems of railway transport development.

The initial adaptation of strategic portfolio management of genetically modified (GM Agro by-products (Ab-Ps is a huge challenge in terms of processing the agro food product supply-chain practices in an environmentally nonthreatening way. As a solution to the challenges, the socio-economic characteristics for SPPS of GM food purchasing scenarios are studied. Evaluation and selection of the GM agro portfolio management are the dynamic issues due to physical and immaterial criteria involving a hybrid multiple criteria decision making (MCDM approach, combining modified grey Decision-Making Trial and Evaluation Laboratory (DEMATEL, Multi-Attributive Border Approximation area Comparison (MABAC and sensitivity analysis. Evaluation criteria are grouped into social, differential and beneficial clusters, and the modified DEMATEL procedure is used to derive the criteria weights. The MABAC method is applied to rank the strategic project portfolios according to the aggregated preferences of decision makers (DMs. The usefulness of the proposed research framework is validated with a case study. The GM by-products are found to be the best portfolio. Moreover, this framework can unify the policies of agro technological improvement, corporate social responsibility (CSR and agro export promotion.

    Reinig, Stephen

    2013-01-01

    Background/Aims Group Health Research Institute (GHRI) utilizes Lean tools and techniques to enhance customer service, monitor compliance, and enhance project team interactions and communications. GHRI’s Grants and Contracts Administration (GCA) recently used Lean tools to design and implement a grant “portfolio management” system and process to support Principal Investigators (PIs). The system tracks six key indicators of funded grants: award status, budgetary spend rate, effort reporting, subaward execution, subawardee invoicing, and progress reporting. The process allows issues to be identified, tracked, and resolved early on with the project team before any serious problems arise. Methods GCA conducted a series of stakeholder interviews to determine the viability of quarterly portfolio review meetings. Project teams liked the idea of discussing the PI’s portfolio, but were leery about quarterly meetings. Therefore, we constructed a process that maximized technology and built in flexibility regarding quarter meetings. The six key indicators were selected, defined, and placed on a dashboard in SharePoint. Each PI has a customized SharePoint page with a calendar showing all major grant deadlines and deliverables; a folder of documents related to the rankings and discussion during each quarterly meeting; and an issue tracker to follow-up on team-identified issues and problems requiring attention. Customer satisfaction data was also collected after each initial quarterly meeting. Results As of October 2012, approximately 25 face-to-face meetings and 5 virtual meetings (i.e., materials and links emailed to the project team) have been completed (210 projects and 85 subawards will have been reviewed by the end of 2012). Satisfaction survey data indicates over 75% of team members (22 of 30 individuals) like the face-to-face meetings and hope to continue the quarterly review process. Conclusions The new portfolio management process has been received favorably by

    As the main body of power grid operation, county-level power supply enterprises undertake an important emission to guarantee the security of power grid operation and safeguard social power using order. The optimization of grid construction projects has been a key issue of power supply capacity and service level of grid enterprises. According to the actual situation of power grid construction project optimization of county-level power enterprises, on the basis of qualitative analysis of the projects, this paper builds a Bi-level programming model based on quantitative analysis. The upper layer of the model is the target restriction of the optimal portfolio; the lower layer of the model is enterprises’ financial restrictions on the size of the enterprise project portfolio. Finally, using a real example to illustrate operation proceeding and the optimization result of the model. Through qualitative analysis and quantitative analysis, the bi-level programming model improves the accuracy and normative standardization of power grid enterprises projects.

    2014-01-01

    Due to the growing importance of IT-based innovations, contemporary firms face an excessive number of proposals for IT projects. As typically only a fraction of these projects can be implemented with the given capacity, IT project portfolio management as a relatively new discipline has received growing attention in research and practice in recent years.?Thorsten Frey demonstrates how companies are struggling to find the right balance between local autonomy and central overview about all projects in the organization. In this context, impacts of different contextual factors on the design of governance arrangements for IT project portfolio management are demonstrated. Moreover, consequences of the use of different organizational designs are analyzed. The author presents insights from a qualitative empirical study as well as a simulative approach.

    Full Text Available In most non-profit organisations (NPOs, there are multiple programs, projects or initiatives running simultaneously. The management of multiple projects in organisations can be coined as project portfolio management (PPM (Archer & Ghasemzadeh 1999; Pennypacker & Dye 2002.  In any project-based organisation, it is critical that selected projects align with and deliver the organisation’s strategy or mission. Decisions about project funding are strategic decisions, particularly when there are resource limitations. In PPM decision making, the allocation of resources to projects requires a clear judgement of value across multiple perspectives. Value has often been expressed in financial terms, however increasingly research indicates that non-financial considerations are equally important in evaluating value. A key task in project portfolio management is to maximise value across the portfolio.  However, value can be a subjective notion, as each person may have different expectations of what is valuable. The involvement of diverse stakeholder interests could create complexities in decision making in non-profit organisations due to value being interpreted in different ways by the stakeholders. Furthermore in order to achieve its purpose, non-profits depend heavily on donors, patrons and sponsors - stakeholders who contribute to the portfolio but are often not the direct recipients of the services provided by the non-profit organisation (Kaplan 2012. Non-profit portfolios often compete with other initiatives for resources and attention from the same donors and sponsors, and may need to constantly justify the value they provide to these stakeholders. Most research about value in PPM has been conducted in the ‘for-profit’ sector. Recent value-based studies in the project portfolio field stress the importance of considering both commercial and non-commercial value in portfolio decision making (Killen, du Plessis & Young 2012; Kopman 2013; Martinsuo

  6. Sustainability-Oriented Financial Resource Allocation in a Project Portfolio through Multi-Criteria Decision-Making

    Full Text Available Modern portfolio theory attempts to maximize the expected return of a portfolio for a given level of portfolio risk, or equivalently minimize risk for a given level of expected return. The reality, however, shows that, when selecting projects to a portfolio and allocating resources in the portfolio, an increasing number of organizations take into account other aspects as well. As a result of the sole purpose (risk-return, it offers only a partial solution for a sustainable organization. Existing project portfolio selection and resource allocation methods and models do not consider sustainability. Therefore, the aim of this article is to develop a sustainability-oriented model of financial resource allocation in a project portfolio by integrating a composite sustainability index of a project into Markowitz’s classical risk-return scheme (mean-variance model. The model was developed by applying multi-criteria decision-making methods. The practicability of the model was tested by an empirical study in a selected construction company. The proposed sustainability-oriented financial resource allocation model could be used in allocating financial resources in any type of business. The use of the model would not only help organisations to manage risk and achieve higher return but would also allow carrying out sustainable projects, thereby promoting greater environmental responsibility and giving more consideration to the wellbeing of future generations. Moreover, the model allows quantifying the impact of the integration of sustainability into financial resource allocation on the return of a portfolio.

    Full Text Available Recent researches have shown that companies face considerable difficulties in assessing the strategy value contribution of Information Technology (IT investments. One of the major obstacles to achieving strategy alignment is that organizations find extremely difficult to link and quantify the IT investments benefits with strategic goals. The aim of this paper is to define an approach to assess portfolio-strategy alignment. To this end a formal specification of Kaplan and Norton Strategy Map is developed utilizing Unified Modeling Language (UML. The approach uses the Strategy Map as a framework for defining the portfolio value contribution and Data Envelopment Analysis (DEA is used as the methodology for measuring efficiency of project portfolios.DOI:10.5585/gep.v3i2.66

    Formal quality-improvement (QI) projects require that participants are educated in QI methods to provide them with the capability to carry out successful, meaningful work. However, orchestrating a portfolio of projects that addresses the strategic mission of the institution requires an extension of basic QI training to provide the division or business unit with the capacity to successfully develop and manage the portfolio. Advanced Improvement Leadership Systems is a program to help units create a meaningful portfolio. This program, used by the Division of Pediatric General and Thoracic Surgery at Cincinnati Children's Hospital Medical Center, helped establish a portfolio of targeted QI projects designed to achieve outstanding outcomes at competitive costs in multiple clinical areas aligned with the institution's strategic goals (improve disease-based outcomes, patient safety, flow, and patient and family experience). These objectives are addressed in an institutional strategic plan built around 5 core areas: Safety, Productivity, Care Coordination and Outcomes, Patient and Family Experience, and Value. By combining the portfolio of QI projects with improvements in the divisional infrastructure, effective improvement efforts were realized throughout the division. In the 9 months following the program, divisional capability resulted in a 16.5% increase (5.7% to 22.2%) of formally trained staff working on 10 QI teams. Concurrently, a leadership team, designed to coordinate projects, remove barriers, and provide technical support, provided the capacity to pursue this ongoing effort. The Advanced Improvement Leadership Systems program increased the Division's efficiency and effectiveness in pursing the QI mission that is integral at our hospital.

    We present a framework for evaluating the risks of investments in climate change mitigation projects to generate emission credits. Risk factors that influence the quantity of emission credits are identified for six project types. Since not all project types are affected by the same factors, diversification is a viable risk reduction strategy. We propose a methodology for quantifying risk and return of such investments, discuss data requirements, and illustrate it using a sample of voluntary projects. In our sample, the returns of an optimally diversified low-risk portfolio are up to 10 times higher than those of single projects, holding risk exposure constant. (author)

    ENGLISH ABSTRACT:The objective of management accounting is to provide management with the financial information that will enable them to make decisions that will result in increased profitability of their organisation. The management accounting of projects in a portfolio as proposed in the literature often presents major problems that prevent the achievement of this objective. These problems include how to estimate value in financial terms during the pre-project phase of the project life cycle as well as the difficulties with financial control of the portfolio of projects as they are conducted. A few case studies are presented highlighting, current practice and the negative effects being experienced. A simple throughput accounting model for the financial management of a portfolio of projects, that could lead to better management decisions and increased profitability of organisations, is proposed.

As criterion of informatization projects' economic efficiency, the total profit maximization due to investments is used. In preliminary calculations, the opportunity of considering continuous dependences of profit on the volume of investments by domain activities is grounded. Eleven classes of such dependences are investigated and analytical solutions and algorithms for solving formulated problems are described.

    Project selection and portfolio management are particularly challenging in the pharmaceutical industry due to the high risk - high stake nature of the drug development process. In the recent years, scholars and industry experts have agreed that traditional Net-Present-Value evaluation of the projects fails to capture the value of managerial flexibility, and encouraged adopting a real options approach to recover the missed value. In this paper, we take a closer look at the drug development process and at the indices currently used to rank projects. We discuss the economic value of information and of real options arising in drug development and present decision analysis as an ideal framework for the implementation of real options valuation.

Survival in a dynamic competitive environment often requires consistent produce of successful new product and services; therefore, implementing an effective Project Portfolio Management (PPM in the organization can improve innovation decisions and outcomes of new products, thereby lead to higher competitive advantage. This Paper aims at discovering the causal relationship of Innovation Project Portfolio Management (IPPM performance. The results of the analysis. Qualitative research design was chosen for this study and through using semi-structured and in-depth interviews with 24 experts in five Iranian organizations producing equipment of the power industry, we use a grounded theory approach to develop a general model of what drives IPPM in detail and how these causes are related to effects on both project performance and business performance. According to the findings from these qualitative data, effective IPPM is the result of three areas of capabilities: IPPM Process, IPPM structure, IPPM people. These causal relationships are moderated by project context. Also the findings show that performance of IPPM consist of an integrated elements of Strategic alignment, portfolio balance, resource fit and value maximization. In the other hand, IPPM performance has influences on project performance and business performance. Finally, a set of propositions regarding the key performance drivers of IPPM were developed. Conclusions and directions of further researches. In conclusion, this study contributes new insights to the emerging research on IPPM. While most IPPM literature is still a theoretical, this paper develops IPPM in the context of the Iran's power industry. The qualitative research design used in this paper was appropriate for gaining an in-depth understanding how the IPPM capabilities and project context, and certain performance constructs are linked to each other.

    There has been a growing interest in the use of portfolios to assess nursing student progress in areas such as critical thinking, problem solving, and communication. The data obtained from student portfolios can be used to improve undergraduate nursing curricula; however in order for change to occur, closing the assessment feedback loop is essential. The portfolio program of one Midwestern school of nursing has successfully used portfolio evidence to effect undergraduate curricular change. This portfolio program, under the direction of the school's Portfolio Subcommittee, involves active participation by students, faculty and administration. Examples of curricular improvements based on portfolio findings included increasing rigor in course assignments, improving student self reflection, promoting students' ability to write in the discipline, and maintaining writing assignments in larger classes.

    Ann Martin, Lin Chambers, Margaret Pippin, & Kate Spruill, NASA The NASA Innovations in Climate Education (NICE) project at Langley Research Center in Hampton, VA, has funded 71 climate education initiatives since 2008. An evaluator was added to the team in mid-2011 to undertake an evaluation of the portfolio. The funded initiatives span across the nation and contribute to the development of a climate-literate public and the preparation of a climate-related STEM workforce through research experiences, professional development opportunities, development of data access and modeling tools, and educational opportunities in both K-12 and higher education. The portfolio of projects also represents a wide range of evaluation questions, approaches, and methodologies. The evaluation of the NICE portfolio has encountered context-specific challenges, including the breadth of the portfolio, the need to build up capacity for electronic project monitoring, and government-wide initiatives to align evaluations across Federal agencies. Additionally, we have contended with the difficulties of maintaining compliance with the Paperwork Reduction Act (PRA), which constrains the ability of NICE to gather data and approach interesting evaluative questions. We will discuss these challenges and our approaches to overcoming them. First, we have committed to fostering communication and partnerships among our awardees and evaluators, facilitating the sharing of expertise, resources, lessons learned and practices across the individual project evaluations. Additionally, NICE has worked in collaboration with NOAA's Environmental Literacy Grants (ELG) and NSF's Climate Change Education Partnerships (CCEP) programs to foster synergy, leverage resources, and facilitate communication. NICE projects, and their evaluators, have had the opportunity to work with and benefit from colleagues on projects funded by other agencies, and to orient their work within the context of the broader tri-agency goals

    Full Text Available Offshore wind farm (WF projects have been promoted by support schemes as part of the expansion of renewable energy resources in Korea. This paper examines in detail how the Renewable Portfolio Standard (RPS, which was adopted post the Feed-in-Tariff scheme in 2012, has had a profound impact on the economic benefits of offshore WFs in Korea. A framework for analyzing the economic viability of RPS is presented and applied to the sixth basic plan for long-term electricity supply and demand in Korea. The electricity market price is forecast using a reformulated probabilistic production cost (PPC model, and the renewable energy certificate (REC price is calculated using its determination rule. The results show that the existing RPS will be ineffective in increasing the penetration of offshore WFs in Korea; however, they also indicate that the economic viability of offshore WFs could be improved by adjusting the existing RPS.

Usually,selecting efficient portfolios from a large number of candidate projects is very complicated,especially when it comes to interdependencies between multiple projects. Previous studies to the problem have some drawbacks when they take into interdependencies among three or more projects into account. Therefore,we propose an improved project portfolio selection model which considers complex interdependencies between three or more projects,and we use NSGA-II to solve the model. The analysis of the numerical example illustrates the effectiveness of the model and the algorithm.

    The CanMEDS framework is ubiquitous in Canadian postgraduate medical education; however, training programs do not have a universal method of assessing competence. We set out to develop a novel portfolio that allowed trainees to generate a longitudinal record of their training and development within the framework. The portfolio provided an objective means for the residency program director to document and evaluate resident progress within the CanMEDS roles.

    2009-01-01

    Mission architectures for human exploration of the lunar surface continue to advance as well as the definitions of capability needs, best practices and engineering design to mitigate the impact of lunar dust on exposed systems. The NASA DMP has been established as the agency focal point for dust characterization, technology, and simulant development. As described in this paper, the DMP has defined a process for selecting and justifying its R&T portfolio. The technology prioritization process, which is based on a ranking system according to weighted criteria, has been successfully applied to the current DMP dust mitigation technology portfolio. Several key findings emerged from this assessment. Within the dust removal and cleaning technologies group, there are critical technical challenges that must be overcome for these technologies to be implemented for lunar applications. For example, an in-situ source of CO2 on the moon is essential to the CO2 shower technology. Also, significant development effort is required to achieve technology readiness level TRL 6 for the electrostatic cleaning system for removal of particles smaller than 50 pm. The baseline materials related technologies require considerable development just to achieve TRL 6. It is also a nontrivial effort to integrate the materials in hardware for lunar application. At present, there are no terrestrial applications that are readily adaptable to lunar surface applications nor are there any obvious leading candidates. The unique requirements of dust sealing systems for lunar applications suggest an extensive development effort will be necessary to mature dust sealing systems to TRL 6 and beyond. As discussed here, several alternate materials and technologies have achieved high levels of maturity for terrestrial applications and warrant due diligence in ongoing assessment of the technology portfolio. The present assessment is the initial step in an ongoing effort to continually evaluate the DMP technology

    2016-04-01

    Scientific Projects today have increased in complexity, requiring multidisciplinarity, and requiring a mix of diverse individuals from different countries who must be integrated into an effective project. Effective team building is one of the prime responsibilities of the project manager. When the project is supported by a funding, the integration and the implication of the different partners are quite easy. Particularly when partners are developing high-performing teams. However, management of research project requires further skills when the budget is not very high and/or when partners are from non-European countries and are not using the same vocabulary. The various cultures, values, beliefs and social usages, particularly with Mediterranean countries cause a special style of communication for an individual or group of individuals. This communication style participates in the success of the project and encompasses a lot of diplomatic skills which will be highlighted.

    In this paper a new approach to prioritize project portfolio in an efficient and reliable way is presented. It is based on strategic objectives of the company and multicriteria decision methods. The paper introduces a rigorous method with acceptable complexity which seeks to assist managers of a big Electrical Company of Venezuela to distribute the annual budget among the possible improvement actions to be conducted on the electrical network of Caracas. A total of 15 network improvement actions grouped into three clusters according to the strategic objectives of the company have been analyzed using the Project Strategic Index (PSI) proposed. The approach combines the use of the Analytic Network Process (ANP) method with the information obtained from the experts during the decision-making process. The ANP method allows the aggregation of the experts' judgments on each of the indicators used into one Project Strategic Index. In addition, ANP is based on utility ratio functions which are the most appropriate for the analysis of uncertain data, like experts' estimations. Finally, unlike the other multicriteria techniques, ANP allows the decision problem to be modelled using the relationships among dependent criteria. The participating experts coincided in the appreciation that the method proposed in this paper is useful and an improvement from traditional budget distribution techniques. They find the results obtained coherent, the process seems sufficiently rigorous and precise, and the use of resources is significantly less than in other methods. (author)

  15. Project Organizations and Their Present and Preferred Culture

    2015-12-01

    Full Text Available Although several research has investigated organizational culture (Schein, 2010; Alvesson, 2013, less research has been conducted on the comparison of present and preferred cultures in project context. This paper aims to fill this gap by focusing on project managers and on the investigation of the present and the preferred culture profile of their project organizations. Based on Cameron and Quinn's (2011 Competing Values Framework using the Organizational Culture Assessment Instrument a quantitative survey was conducted. The questionnaire used gathered data from project managers working in various industries and organizations. The sample consisted of 695 respondents. The empirical study by focusing on project organizations hypothesizes that four project organization groups can be revealed based on their dominant cultural orientation. To test this hypothesis cluster analysis was used. The study also hypothesizes that the present and preferred culture profiles of project organizations do not show significant difference. To prove this statement paired samples t-test was chosen. The results showed that instead of four groups of project organizations with one dominant culture type, there are only three project organizations with the domination of one culture type. Continuing the investigation with these three project organizations, the present and preferred project culture profiles were compared. The results showed that in all three project organizations there are differences between the present and preferred project culture profiles. These differences are manifested mainly by the change of the dominant culture type but the remaining culture types determining the culture profile of the project organizations also show differences.

  16. Weighing the Costs and Benefits of Renewables Portfolio Standards:A Comparative Analysis of State-Level Policy Impact Projections

    Energy Technology Data Exchange (ETDEWEB)

    Chen, Cliff; Wiser, Ryan; Bolinger, Mark

    2007-01-16

    State renewables portfolio standards (RPS) have emerged as one of the most important policy drivers of renewable energy capacity expansion in the U.S. Collectively, these policies now apply to roughly 40% of U.S. electricity load, and may have substantial impacts on electricity markets, ratepayers, and local economies. As RPS policies have been proposed or adopted in an increasing number of states, a growing number of studies have attempted to quantify the potential impacts of these policies, focusing primarily on projecting cost impacts, but sometimes also estimating macroeconomic and environmental effects. This report synthesizes and analyzes the results and methodologies of 28 distinct state or utility-level RPS cost impact analyses completed since 1998. Together, these studies model proposed or adopted RPS policies in 18 different states. We highlight the key findings of these studies on the costs and benefits of RPS policies, examine the sensitivity of projected costs to model assumptions, assess the attributes of different modeling approaches, and suggest possible areas of improvement for future RPS analysis.

    Over the past ten years, AREVA has performed D and D operations on a wide range of nuclear sites, such as Marcoule and La Hague recycling plants, to Cadarache MOX fuel fabrication plant or Veurey and Annecy metallic Uranium machining plants. Each site is different from the other but some lessons can be shared through this D and D portfolio. In that respect, knowledge management is one of AREVA D and D Technical Department main missions. Four illustrations demonstrate the interest of knowledge share. Waste management is one of the key activities in D and D; It requires a specific characterization methodology, adapted logistics, and optimized waste channels, all of which have been developed over the years by AREVA teams on the site of Marcoule while they are rather new to La Hague, whose main activity remains fuel reprocessing despite the launch of UP2 400 D and D program. The transfer of know how has thus been organized over the past two years. Plasma cutting has been used extensively in Marcoule for years, while prohibited on the site of La Hague following questions raised about the risks associated wit Ruthenium sublimation. La Hague Technical Department has thus developed an experimental protocol to quantify and contain the Ruthenium risk, the result of which will then be applied to Marcoule where the Ruthenium issue has appeared in recent operations. Commissioning and operating fission products evaporators is a rather standard activity on UP2 800 and UP3, while the associated experience has been decreasing in Marcoule following final shutdown in 1998. When the French atomic Energy commission decided to build and operate a new evaporator to concentrate rinsing effluents prior to vitrification in 2009, AREVA La Hague operators were mobilized to test and commission the new equipment, and train local operators. Concrete scabbling is the final stage prior to the free release of a nuclear facility. In the context of Veurey and Annecy final cleanup and declassification

    A constant rebalanced portfolio is an asset allocation algorithm which keeps the same distribution of wealth among a set of assets along a period of time. Recently, there has been work on on-line portfolio selection algorithms which are competitive with the best constant rebalanced portfolio determined in hindsight (Cover, 1991; Helmbold et al., 1996; Cover and Ordentlich, 1996). By their nature, these algorithms employ the assumption that high returns can be achieved using a fixed asset allocation strategy. However, stock markets are far from being stationary and in many cases the wealth achieved by a constant rebalanced portfolio is much smaller than the wealth achieved by an ad hoc investment strategy that adapts to changes in the market. In this paper we present an efficient portfolio selection algorithm that is able to track a changing market. We also describe a simple extension of the algorithm for the case of a general transaction cost, including the transactions cost models recently investigated in (Blum and Kalai, 1997). We provide a simple analysis of the competitiveness of the algorithm and check its performance on real stock data from the New York Stock Exchange accumulated during a 22-year period. On this data, our algorithm outperforms all the algorithms referenced above, with and without transaction costs.

    2001-02-01

    Eager to capitalize on the Internet's potential, many companies have allowed scores of on-line projects to bubble up throughout their organizations. The result? More harm than good, as companies find themselves confusing customers, aggravating employees, and wasting bushels of money. In this article, consultant Anthony Tjan explains how companies can do better. By adapting classical portfolio strategy to the digital age, executives can coordinate their Internet initiatives to avoid the needless headaches and spending, he says. Much of the market and industry data that underpin traditional portfolio analysis is unavailable for the Internet space, so Tjan replaces the two criteria used in traditional portfolio analysis--market position and industry attractiveness--with business viability and business fit. Viability captures the available quantitative data about an investment's likely payoff. Fit is qualitative; it measures the degree to which an investment dovetails with a company's existing processes, capabilities, and culture. Using viability and fit to assess their online initiatives, companies can then plot these efforts onto a simple matrix, called an Internet portfolio map. Their location on the matrix will suggest whether each initiative should be invested in, redesigned, sold or spun out, or killed. As Tjan notes, the process of organizing and evaluating new investment options against coherent, meaningful criteria isn't new. In the digital era, what is new are the tools you use. Internet portfolio planning is one such tool.

    Alarcón, Renato D

    2009-10-01

    This paper aims to provide conceptual justifications for the inclusion of culture and cultural factors in psychiatric diagnosis, and logistic suggestions as to the content and use of this approach. A discussion of the scope and limitations of current diagnostic practice, criticisms from different quarters, and the role and relevance of culture in the diagnostic encounter, precede the examination of advantages and disadvantages of the approach. The cultural content of psychiatric diagnosis should include the main, well-recognized cultural variables, adequate family data, explanatory models, and strengths and weaknesses of every individual patient. The practical aspects include the acceptance of "cultural discordances" as a component of an updated definition of mental disorder, and the use of a refurbished cultural formulation. Clinical "telescoping" strategies to obtain relevant cultural data during the diagnostic interview, and areas of future research (including field trials on the cultural formulation and on "culture bound syndromes"), are outlined.

    An excellent demonstration of how meaningful and valuable conferences devoted to the topic of project and portfolio management in the pharmaceutical industry can be, was given at an event organized in Barcelona, September 2008. Thus, over this 2-day meeting the delegates were updated on the state of the art in this wide-reaching area from speakers representing an array of companies; from small, relatively new players, via mid-sized, to established large and big pharmas. One common theme that emerged was the importance of assessing the value of drug projects as correctly as possible, especially under the current financial climate and the many challenges facing the industry. Furthermore, experiences from constructing portfolios with the aim to minimize risk and maximize return on investment were shared alongside mathematical approaches to obtain the data required for this purpose and accounts of the pleasures and hardships working in a global context and in partnership constellations.

  2. Portfolio generation goes beyond project selection: interdependencies must drive new alternatives creation A geração de carteiras ultrapassa a seleção de projetos: deve ser guiada pelas interdependências entre os projetos

    2013-03-01

    Full Text Available The portfolio management literature mainstream, the Project Selection Paradigm, regards projects as closed packages ready for choice. However, to generate a portfolio, such packages must be opened to reveal the inside sources of interdependencies among them. Then, the project elements so found may be recombined into new alternatives that better capture the synergies among projects and avoid negative interactions. Thus project selection can be superseded by a Project Portfolio Generation based on a projects' and portfolios' reformulation process.Centrada na Seleção de Projetos, a literatura de gestão de carteiras trata os projetos como pacotes fechados prontos para escolha. Contudo, para gerar uma carteira, tais pacotes precisam ser abertos para revelar as fontes interiores das interdependências entre eles. Na sequência, os elementos dos projetos encontrados nessa análise podem ser recombinados em novas alternativas que melhor expressem as sinergias entre os projetos e evitem suas interações negativas. Assim, a mera Seleção de Projetos pode ser superada por um processo de Geração da Carteira de Projetos que se apoia num processo de reformulação de projetos e carteiras.

    Full Text Available In recent years culture has become one of the most studied topicsin project management research. Some studies have investigatedthe infl uence of culture at different levels – such as nationalculture, industry culture, organisational culture and professionalculture. As a project-based industry, the construction industryneeds to have more insight concerning cultural issues at theproject level and their infl uence on the performance of constructionprojects. Few studies, however, have focused on culture at theproject level. This paper uses a questionnaire survey to determinethe perceptions of Chinese contractors about the impact of projectculture on the performance of local construction projects. This isaugmented by a series of in-depth interviews with senior executivemanagers in the industry. The fi ndings indicate that specifi c projectculture does contribute signifi cantly towards project outcomes.In particular, goal orientation and fl exibility, as two dimensionsof project culture, have a negative statistical correlation withperceived satisfaction of the process, commercial success, futurebusiness opportunities, lessons learnt from the project, satisfactionwith the relationships, and overall performance. This paper alsoindicates that the affordability of developing an appropriate projectculture is a major concern for industry practitioners.

    2008-01-07

    State renewables portfolio standards (RPS) have emerged as one of the most important policy drivers of renewable energy capacity expansion in the U.S. As RPS policies have been proposed or adopted in an increasing number of states, a growing number of studies have attempted to quantify the potential impacts of these policies, focusing primarily on cost impacts, but sometimes also estimating macroeconomic, risk reduction, and environmental effects. This article synthesizes and analyzes the results and methodologies of 31 distinct state or utility-level RPS cost-impact analyses completed since 1998. Together, these studies model proposed or adopted RPS policies in 20 different states. We highlight the key findings of these studies on the projected costs of state RPS policies, examine the sensitivity of projected costs to model assumptions, evaluate the reasonableness of key input assumptions, and suggest possible areas of improvement for future RPS analyses. We conclude that while there is considerable uncertainty in the study results, the majority of the studies project modest cost impacts. Seventy percent of the state RPS cost studies project retail electricity rate increases of no greater than one percent. Nonetheless, there is considerable room for improving the analytic methods, and therefore accuracy, of these estimates.

    Science.gov (United States)

    O'Sullivan, Patricia; Greene, Constance

    2002-11-01

    Portfolios are an innovative approach to evaluate the competency of emergency medicine residents. Three key characteristics add to their attractiveness. First, portfolios draw from the resident's actual work. Second, they require self-reflection on the part of the resident. Third, they are inherently practice-based learning since residents must review and consider their practice in order to begin the portfolio. This paper illustrates five different applications of portfolios. First, portfolios are applied to evaluating specific competencies as part of the training of emergency physicians. While evaluating specific competencies, the portfolio captures aspects of the general competencies. Second, the article illustrates using portfolios as a way to address a specific residency review committee (RRC) requirement such as follow-ups. Third is a description of how portfolios can be used to evaluate resident conferences capturing the competency of practice-based learning and possibly other competencies such as medical knowledge and patient care. Fourth, the authors of the article designed a portfolio as a way to demonstrate clinical competence. Fifth, they elaborate as to how a continuous quality improvement project could be cast within the portfolio framework. They provide some guidance concerning issues to address when designing the portfolios. Portfolios are carefully structured and not haphazard collections of materials. Following criteria is important in maintaining the validity of the portfolio as well as contributing to reliability. The portfolios can enhance the relationship between faculty and residents since faculty will suggest cases, discuss anomalies, and interact with the residents around the portfolio. The authors believe that in general portfolios can cover many of the general competencies specified by the ACGME while still focusing on issues important to emergency medicine. The authors believe that portfolios provide an approach to evaluation commensurate

    A geometric analysis of return time series, performed in the past, implied that most of the systematic information in the market is contained in a space of small dimension. Here we have explored subspaces of this space to find out the relative performance of portfolios formed from companies that have the largest projections in each one of the subspaces. As expected, it was found that the best performance portfolios are associated with some of the small eigenvalue subspaces and not to the dominant dimensions. This is found to occur in a systematic fashion over an extended period (1990-2008).

    A culture of quality improvement (QI) values collaboration, transparency, and staff empowerment. Organizations exhibiting a culture of QI are more likely to engage in QI. We examined whether local health departments' (LHDs') participation in a longitudinal, experiential QI training program changes QI culture. Prior to and following participation in a QI training program, all employees of participating LHDs were asked to complete an 8-item survey assessing components of QI culture on a 5-point scale. From 2010 to 2015, multidisciplinary teams from North Carolina LHDs participated in sequential cohorts of a 6-month QI training program, during which the teams completed a QI project. We dichotomized culture survey responses, with 4 or 5 being "Supportive." We compared adjusted proportions, using linear regression, clustering at LHD, and controlling for cohort. Data from 42 LHDs were included. At baseline, 7.8% responded that their LHD had a supportive culture for all 8 components, compared with 12% at follow-up (P cultures increased for all components of culture including communication by 4.1% (95% CI: 2.0%-6.2%), problem solving by 2.9% (95% CI: 1.6%-5.5%), team work by 5.2% (95% CI: 2.5%-7.8%), vision by 4.3% (95% CI: 1.1%-7.5%), performance measures by 5.6% (95% CI: 1.6%-9.6%), recognition by 4.7% (95% CI: 1.4%-8.0%), for conflict by 5.5% (95% CI: 1.7%-9.4%), and alignment by 5.8% (95% CI: 2.3%-9.2%). Engagement with structured QI training programs-and perhaps simply completing QI projects-can cause small, but important changes in organizations' cultures, thus increasing engagement in future QI and improving overall care and services. The article demonstrates that when LHDs participate in a longitudinal, experiential QI training program, their cultures of QI improve. Local health departments participating in similar training programs might experience similar improvements in culture, increasing subsequent participation in QI projects and improving related health

Due to resource scarcity, decision makers have to be faced with the R&D project portfolio selection problems. In this paper, a conception of dependence assignment matrix is formulated to quantify the interaction in a portfolio based on multi-interdependences among projects in the process of complex product development. An improved non-linear planning model for R&D project portfolio selection is developed in consideration of combined benefit, resource and technology interaction. A solving method to find a satisfying portfolio is designed and implemented based on simulated annealing algorithm. Finally, the proposed method is applied to R&D project portfolio management practice in a domestic auto company. Experimental results show that the method is reasonable and effective.

    In order to obtain more economic benefits, most water conservancy enterprises now adopt portfolio management ori-ented towards a number of related projects under the guidance of their overall strategic targets rather than managing a single pro-ject individually. According to the relevance of different projects, a mathematical model is established for water conservancy en-terprises to select projects in the process of portfolio management based on integer programming, which aims at the optimal combi-nation of projects and the maximum benefits of the enterprise. With a water conservancy enterprise as an example, portfolio man-agement is applied to the engineering projects awarded to the enterprise, and the combination of projects which may bring about the maximum benefits is selected. Through the example, the applicability and scientific values of project portfolio management for water conservancy enterprise are proved.%目前,多数水利企业为了获得更高的经济效益已不再仅仅对单个水利项目进行单独管理,而是在企业总体战略目标的指导下对多个相关项目进行组合管理。根据项目之间的相关性,利用整数规划算法构建了水利企业在采用项目组合管理时进行项目选择的数学模型,从而筛选出最优的项目组合,实现企业效益最大化的目标。以某水利企业为例,对其中标的若干个工程项目进行组合管理,选择使其获得最大利润的项目组合。由此阐明在水利企业中应用项目组合管理的适用性和科学性。

  7. Assessing local resources and culture before instituting quality improvement projects.

    Science.gov (United States)

    Hawkins, C Matthew

    2014-12-01

    The planning phases of quality improvement projects are commonly overlooked. Disorganized planning and implementation can escalate chaos, intensify resistance to change, and increase the likelihood of failure. Two important steps in the planning phase are (1) assessing local resources available to aid in the quality improvement project and (2) evaluating the culture in which the desired change is to be implemented. Assessing local resources includes identifying and engaging key stakeholders and evaluating if appropriate expertise is available for the scope of the project. This process also involves engaging informaticists and gathering available IT tools to plan and automate (to the extent possible) the data-gathering, analysis, and feedback steps. Culture in a department is influenced by the ability and willingness to manage resistance to change, build consensus, span boundaries between stakeholders, and become a learning organization. Allotting appropriate time to perform these preparatory steps will increase the odds of successfully performing a quality improvement project and implementing change.

    This report documents a study with the objective of enhancing safety culture in the Swedish nuclear power industry. A primary objective of this study was to ensure that the latest thinking on human factors principles was being recognised and applied by nuclear power operators as a means of ensuring optimal safety performance. The initial phase of the project was conducted as a pilot study, involving the senior management group at one Swedish nuclear power-producing site. The pilot study enabled the project methodology to be validated after which it was repeated at other Swedish nuclear power industry sites, providing a broad-ranging analysis of opportunities across the industry to enhance safety culture. The introduction to this report contains an overview of safety culture, explains the background to the project and sets out the project rationale and objectives. The methodology used for understanding and analysing the important safety culture issues at each nuclear power site is then described. This section begins with a summary of the processes used in the information gathering and data analysis stage. The six components of the Management Workshops conducted at each site are then described. These workshops used a series of presentations, interactive events and group exercises to: (a) provide feedback to site managers on the safety culture and safety leadership issues identified at their site, and (b) stimulate further safety thinking and provide 'take-away' information and leadership strategies that could be applied to promote safety culture improvements. Section 3, project Findings, contains the main observations and output from the project. These include: - a brief overview of aspects of the local industry operating context that impinge on safety culture; - a summary of strengths or positive attributes observed within the safety culture of the Swedish nuclear industry; - a set of identified opportunities for further improvement; - the aggregated

  12. Constant Proportion Portfolio Insurance

    DEFF Research Database (Denmark)

    Jessen, Cathrine

    2014-01-01

    Portfolio insurance, as practiced in 1987, consisted of trading between an underlying stock portfolio and cash, using option theory to place a floor on the value of the position, as if it included a protective put. Constant Proportion Portfolio Insurance (CPPI) is an option-free variation...... on the theme, originally proposed by Fischer Black. In CPPI, a financial institution guarantees a floor value for the “insured” portfolio and adjusts the stock/bond mix to produce a leveraged exposure to the risky assets, which depends on how far the portfolio value is above the floor. Plain-vanilla portfolio...... insurance largely died with the crash of 1987, but CPPI is still going strong. In the frictionless markets of finance theory, the issuer’s strategy to hedge its liability under the contract is clear, but in the real world with transactions costs and stochastic jump risk, the optimal strategy is less obvious...

  13. Risk modelling in portfolio optimization

    Lam, W. H.; Jaaman, Saiful Hafizah Hj.; Isa, Zaidi

    2013-09-01

    Risk management is very important in portfolio optimization. The mean-variance model has been used in portfolio optimization to minimize the investment risk. The objective of the mean-variance model is to minimize the portfolio risk and achieve the target rate of return. Variance is used as risk measure in the mean-variance model. The purpose of this study is to compare the portfolio composition as well as performance between the optimal portfolio of mean-variance model and equally weighted portfolio. Equally weighted portfolio means the proportions that are invested in each asset are equal. The results show that the portfolio composition of the mean-variance optimal portfolio and equally weighted portfolio are different. Besides that, the mean-variance optimal portfolio gives better performance because it gives higher performance ratio than the equally weighted portfolio.

A catalogue of studies has been performed in a set of cultures such as the Megalithic Phenomenon, ancient Egypt, Middle East Bronze and Iron Age civilizations and the Roman World, among many others. In this essay a general scope of the project and a series of most interesting outcomes will be presented. The evolutionary ties of the megalithic monuments of the Iberian Peninsula and elsewhere, the pattern of orientation of Egyptian temples and skyscaping practices within the Hittite, Commagenian or Nabataean cultures, among others, will be shown; finishing in a comprehensive, statistical and comparative study of the orientation patterns of thousands of ancient monuments of the Mediterranean region. Finally, a sketch of our most recent, still ongoing, research on the astronomical and non-astronomical practices used in the planning of cities in the Roman World will be a compelling and promising closing remark of our analysis.

  10. A conceptual approach to studying the organisational culture of construction projects

    Directory of Open Access Journals (Sweden)

    Thayaparan Gajendran

    2012-05-01

    Full Text Available Studying the culture of project organisations requires a robust theoretical framework, which provides a platform for generating understanding. It is argued that cultural analysis frameworks are most effectively conceptualised from multiple philosophical and multi-methodological positions. To this end this paper presents a cultural analysis framework for studying construction project organisations, based on a synthesis of the culture literature. Four key aspects underpinning organisational cultural framework are explored: the paradigms used to conceptualise organisational culture, the methods by which individuals represent and assess cultural dimensions, the cultural perspectives assumed by the observer when defining and describing culture, and the managers’ orientation to culture in their organisations. The proposed framework comprises three synthesised cultural philosophical positions: integration-technical, differentiation-practical and fragmentation-emancipation. These philosophical positions span the polar extremes defining the cultural paradigm continuum, which together provide researchers and organisational managers with a sound foundation from which to study the culture of project organisations.

    Managements in the organizations deal daily with decision making, today the market competitiveness requires rationality and efficiency. In the project portfolio management a lot of questions emerge to the management, such as: The projects chosen are really the best projects? They are suitable for the reality of the company? The evaluation criteria are appropriate? The methodology employed is adequate? The application of resources is optimized? There is a real commitment from all levels of the organizational structure? In this context, the objective of this work is to describe a model that try to be more applied to the reality, taking into consideration conceptual and motivational aspects related to the implementation of project management involving high investment with restrictions on resources, and still provide a tool to support decision .

  13. Enhancing reliability in portfolio assessment: 'shaping' the portfolio.

    Science.gov (United States)

    Pitts, John; Coles, Colin; Thomas, Peter

    2001-07-01

    This paper reports a follow-on project that assessed a series of portfolios assembled by a cohort of participants attending a course for prospective general practice trainers. In an attempt to enhance reliability, a framework for defining and addressing problems using a reflective practice model was offered to participants. The reliability of the judgements made by a panel of assessors about individual 'components', together with an overall global judgement about performance were studied. The reliability of individual assessors' judgements (i.e. their consistency) was moderate, but inter-rater reliability did not reach a level that could support making a safe summative judgement. Despite offering a possible structure for demonstrating reflective processes, the levels of reliability reached were similar to the earlier work and other subjective assessments generally, and perhaps reflected individuality of personal agendas of both the assessed and the assessors, and variations in portfolio structure and content; even agreement among the assessors about evidence of the framework being used was poor. Suggestions for approaches in the future are made. The conclusion remains that while portfolios might be valuable as resources for learning, as assessment tools they should be treated as problematic.

    Lowe, Andrew; Hayward, Brent (Dedale Asia Pacific, Albert Park VIC 3206 (Australia))

    2006-08-15

    This report documents a study with the objective of enhancing safety culture in the Swedish nuclear power industry. A primary objective of this study was to ensure that the latest thinking on human factors principles was being recognised and applied by nuclear power operators as a means of ensuring optimal safety performance. The initial phase of the project was conducted as a pilot study, involving the senior management group at one Swedish nuclear power-producing site. The pilot study enabled the project methodology to be validated after which it was repeated at other Swedish nuclear power industry sites, providing a broad-ranging analysis of opportunities across the industry to enhance safety culture. The introduction to this report contains an overview of safety culture, explains the background to the project and sets out the project rationale and objectives. The methodology used for understanding and analysing the important safety culture issues at each nuclear power site is then described. This section begins with a summary of the processes used in the information gathering and data analysis stage. The six components of the Management Workshops conducted at each site are then described. These workshops used a series of presentations, interactive events and group exercises to: (a) provide feedback to site managers on the safety culture and safety leadership issues identified at their site, and (b) stimulate further safety thinking and provide 'take-away' information and leadership strategies that could be applied to promote safety culture improvements. Section 3, project Findings, contains the main observations and output from the project. These include: - a brief overview of aspects of the local industry operating context that impinge on safety culture; - a summary of strengths or positive attributes observed within the safety culture of the Swedish nuclear industry; - a set of identified opportunities for further improvement; - the aggregated

    Full Text Available O artigo traz um levantamento dos principais modelos de gerenciamento do portfólio de projetos (PPM e uma análise crítica para a construção do quadro teórico. Neste estudo, foram realizados quatro estudos de caso em diferentes setores, com o objetivo de identificar as principais práticas de PPM adotadas, o estágio de implementação e a relação entre as práticas e os resultados obtidos. Os principais resultados indicam que o PPM ainda é pouco presente nas organizações, e que a falta dele é um dos fatores que dificultam a implementação adequada das ações estratégicas definidas pelos executivos. O desdobramento das ações estratégicas em projetos e a delegação da responsabilidade pela execução dos projetos aos níveis inferiores, de forma desestruturada, promovem conflitos desnecessários, com perda de energia da organização.This article consists of a review of the literature on the main PPM models, in addition to a critical analysis to build a theoretical framework. Four case studies are presented of companies from different sectors, which aim to identify the main PPM practices adopted, their implementation stage and the relations between those practices and the benefits obtained. The main research results show that PPM is still rarely present in organizations. The lack of PPM may be one of the factors hampering the correct implementation of strategic actions defined by the executive team. The deployment of strategic actions in projects and the structureless delegation of responsibility for implementation to mid- level managers creates unnecessary conflicts, with a consequential loss of an organization’s energy.

    Teaching portfolios are stimulating much discussion as more comprehensive approaches to evaluating teaching are sought. Portfolios can be used effectively for both formative and summative evaluative purposes. The content of a portfolio may vary greatly, but commonly includes material that reflects student learning, evaluative materials, and a personal statement on the faculty's philosophy of education. Professional growth often accompanies developing a personal teaching portfolio.

Betaville is a massively participatory online environment for distributed 3D design and development of proposals for changes to the built environment– an experimental integration of art, design, and software development for the public realm. Through a detailed account of Betaville from a Big Crazy Idea to a working "deep social medium", the author examines the current conditions of performance and accessibility of hardware, software, networks, and skills that can be brought together into a new form of open public design and deliberation space, for and spanning and integrating the disparate spheres of art, architecture, social media, and engineering. Betaville is an ambitious enterprise, of building compelling and constructive working relationships in situations where roles and disciplinary boundaries must be as agile as the development process of the soft...

  15. A Bicriteria Approach Identifying Nondominated Portfolios

    Directory of Open Access Journals (Sweden)

    Javier Pereira

    2014-01-01

    Full Text Available We explore a portfolio constructive model, formulated in terms of satisfaction of a given set of technical requirements, with the minimum number of projects and minimum redundancy. An algorithm issued from robust portfolio modeling is adapted to a vector model, modifying the dominance condition as convenient, in order to find the set of nondominated portfolios, as solutions of a bicriteria integer linear programming problem. In order to improve the former algorithm, a process finding an optimal solution of a monocriteria version of this problem is proposed, which is further used as a first feasible solution aiding to find nondominated solutions more rapidly. Next, a sorting process is applied on the input data or information matrix, which is intended to prune nonfeasible solutions early in the constructive algorithm. Numerical examples show that the optimization and sorting processes both improve computational efficiency of the original algorithm. Their limits are also shown on certain complex instances.

A pesquisa realizada tem caráter qualitativo, sendo a abordagem adotada o estudo de caso longitudinal. A pesquisa foi desenvolvida em uma empresa do setor químico brasileiro. As evidências, de várias fontes, foram coletadas através de entrevistas, documentos e dados dos sistemas corporativos. Para a compreensão do portfólio de projetos da empresa foram coletados e analisados dados de mil projetos realizados entre 2001 e 2005. Os resultados indicam que maior atenção é dada à etapa de seleção, negligenciando a etapa de ajuste. A adoção de ferramentas de balanceamento permitiu evidenciar lacunas e fontes de desbalanceamento no portfólio de projetos, promovendo o debate entre os tomadores de decisão no que concerne ao viés introduzido pelos critérios adotados na etapa de seleção e levantando a necessidade de introdução de uma sistemática de ajuste e balanceamento. Observou-se que sem uma adequada categorização dos projetos da empresa seria difícil promover a análise de balanceamento.This article aims to understand the adjustment stage of project portfolio management, highlighting its relationship with the processes of categorization and balancing.

    Project Portfolio Selection is known as the essential element of strategic project management and deci⁃sion. There are also some disadvantages in model and methods which are based on the project portfolio selection considering interdependencies and preference incorporation of decision maker. The paper proposes an novel outran⁃king model to classify the preference relationship between different projects, and it also bring the synergies and in⁃terdependencies into consideration which makes the model more complete. Moreover, it proposes the improved par⁃ticle swarm optimization algorithm based on the model which speeds up convergence an expand the diversity of non⁃dominant solutions simultaneously. In the restrained condition of preferences incorporation and interdependencies, the paper comes up with the experiments to verify the model and method respectively. The results indicate that the non⁃dominant solutions achieved by the outranking model are likely to the optimum of project portfolio selection, and the improved particle swarm optimization search the results faster.%项目组合选择是战略项目管理决策的重要环节,目前基于决策者偏好的交互项目组合选择的研究仍然在模型和算法上存在不足。首先提出级别优先模型细致划分了项目间的偏好关系,并引入了项目间的协同交互,使模型更加完备。进而结合该模型改进了多目标粒子群算法,加快其收敛速度,并拓展其非劣解的多样性。在考虑决策者偏好和项目间交互约束的条件下,分别对偏好模型和模型求解算法进行了仿真验证。仿真结果表明,采用级别优先模型所得的非劣解更加接近项目组合选择的最优解,改进粒子群算法的搜索速度更快。

    Full Text Available Abstract Due to globalization and dynamic business environment, teams in companies are multicultural; as a result, culture may become an important aspect to be considered. The majority of articles regarding projects include factors of success and failure, but only a few embrace cultural perspectives. To provide more insight into the effects of cultural perspectives, this paper presents findings from an exploratory study that investigated how Brazilian information technology companies perceive project success and failure, and then makes inferences regarding the cultural factors. Interviews and questionnaires were applied, and the results provide insights for understanding how cultural factors may influence the project success perceptions. As the primary results, contributions regarding cultural perceptions are offered and related to different dimensions with a view to exploring the cultural aspects as determinant factors of success in a project management environment.

  9. An Investigation into Cultural Dimensions of Construction Professionals Working for International Projects in Oman

    Directory of Open Access Journals (Sweden)

    2016-04-01

    Full Text Available International construction projects involve multinational participants with different nationalities and cultural backgrounds. To execute international projects, construction companies easily face significant risks which hinder the capability to create profits and degrade company credibility. One of the major risk factors affecting project performance and success is cultural characteristics of project participants, especially expatriates, working in international construction projects. This research investigates the cultural dimensions of Indian, Sri Lankan and British construction professionals working for international projects in Oman. Cultural dimensions have been surveyed by a quantitative approach. The outcomes indicate that even though these professionals are working in the same construction industry and currently in similar working environments, their cultural dimensions are mainly influenced by national culture. Further Asian participants of the survey showed lower Power Distance Index (PDI and Uncertainty Avoidance Index (UAI than their national cultural dimensions. This is a reflection of westernization of their companies in the international construction markets. Also lower Long Term Orientation (LTO indicates the temporary tendency of employment in international construction projects. Further research will need to focus on the relationship between corporate culture and national culture to complete the entire picture of culture in construction.

  15. Improving intercultural competency in global IT projects through recognition of culture-based behaviors

    Directory of Open Access Journals (Sweden)

    Richard Amster

    2016-01-01

    Full Text Available The success of global IT projects is highly influenced by culture-based behaviors. Issues between individuals arise when behaviors are (mis-perceived, (mis-interpreted, and (mis-judged by using the perceiver’s expectations, beliefs, and values. Misperception results when the behavior is not anticipated because it would not occur in ones own culture. As a result, behavior should be the starting point for cross-cultural research. But, studies have primarily focused on belief and value systems which are more abstract and less specific than behaviors. This paper presents a study that analyzed cultural behavioral differences between Indian project managers and their counterparts in other countries. The conducted qualitative, semi-structured interviews revealed insights into cross-cultural challenges and shed light on the complex ways that culture-based behaviors impact IT projects. The study identified 127 behaviors that significantly affected project success and cross-cultural cooperation between Indian managers and managers from all over the world. These behaviors were grouped into 19 behavior clusters. Understanding these behavior clusters, and correlating these behaviors to values and beliefs, will improve project collaboration, and inform cross-cultural training strategies. In addition, existing cultural dimensions were reduced in scope, additional dimensions were defined for clarity, and new business-related dimensions were identified. Finally, based on the study’s results, the paper suggests four important components that should be added to cross-cultural training programs for international project managers.

  1. Decentralized Portfolio Management

    Benjamin Miranda Tabak

    2003-12-01

    Full Text Available We use a mean-variance model to analyze the problem of decentralized portfolio management. We find the solution for the optimal portfolio allocation for a head trader operating in n different markets, which is called the optimal centralized portfolio. However, as there are many traders specialized in different markets, the solution to the problem of optimal decentralized allocation should be different from the centralized case. In this paper we derive conditions for the solutions to be equivalent. We use multivariate normal returns and a negative exponential function to solve the problem analytically. We generate the equivalence of solutions by assuming that different traders face different interest rates for borrowing and lending. This interest rate is dependent on the ratio of the degrees of risk aversion of the trader and the head trader, on the excess return, and on the correlation between asset returns.

    selection process involves interests and risks, an effective project portfolio management can provide effective support. This paper aims to provide an overview of academic literature on project portfolio management describing trends and the key topics. The methodological approach chosen was a literature review, adopting bibliometric techniques and content analysis. The search was conducted in the ISI Web of Knlowledge and Scielo databases. The initial sample for analysis consisted of 85 articles published between 1994 and 2009 and included the cited references. The sample was analyzed according to the evolution of publications and citations and identification of key journals, authors, studies, and topics. The results indicate a significant increase in the volume of published papers and citations over the period of time studied. The portfolio management models identified in the literature converge on the following key processes: project proposals, strategic drivers, identification, evaluation, selection, prioritization, resource allocation, and monitoring & control. The most cited tools in the studies in the sample were classified into three groups: financial methods, mathematical programming, and statistical models. Finally, the portfolio selection criteria that stood out were market potential, economic and financial feasibility, and risks and uncertainties.

    2017-04-01

    Full Text Available In this study we are trying with the help of portfolio in teacher training and the diagnosis of the learning group concerning their skills in translation from German to Turkish, to show the documentation of the learning process. The portfolio provides a good overview about the performance of the students and it also prepares a basis for assessment. A growing self-awareness of students can be achieved through implementing the portfolio-method. The students should collect and reflect the most important materials and practices leading to key terms of the seminar. It is more than an assessment method it is a surrounding of learning. The work with portfolio has an influence on teaching, learning and assessing. As in detail, this is dependent on the aims and other characteristics of the models which take the portfolio work as a basis. The portfolio provides us a big advantage for the support of the cultural reflection. We can observe the process of the growth of knowledge step by step, because the measurement of the development in a determined period allows us either a written work or a Multiple Choice Test. In this sense we can look at the portfolio as an assessment instrument of a process.

    Brodie, Joshua; Daubechies, Ingrid; De Mol, Christine; Giannone, Domenico; Loris, Ignace

    2009-07-28

    We consider the problem of portfolio selection within the classical Markowitz mean-variance framework, reformulated as a constrained least-squares regression problem. We propose to add to the objective function a penalty proportional to the sum of the absolute values of the portfolio weights. This penalty regularizes (stabilizes) the optimization problem, encourages sparse portfolios (i.e., portfolios with only few active positions), and allows accounting for transaction costs. Our approach recovers as special cases the no-short-positions portfolios, but does allow for short positions in limited number. We implement this methodology on two benchmark data sets constructed by Fama and French. Using only a modest amount of training data, we construct portfolios whose out-of-sample performance, as measured by Sharpe ratio, is consistently and significantly better than that of the naïve evenly weighted portfolio.

    It is traditionally assumed that licensure of healthcare professionals means that they are minimally competent. Many nursing specialty organizations offer examinations and other processes for certification, suggesting that certification is associated with continued competency. Can standardized examination for certification and continuing education for recertification ensure continued competency? Continuing education and testing provide a limited picture of an individual's knowledge and/or skill acquisition in a limited area at one point in time. However, portfolios promote critical thinking, self-assessment, and individual accountability. A portfolio is a portable mechanism for evaluating competencies that may otherwise be difficult to assess. This article summarizes some of the literature addressing portfolios, including aspects of portfolio development process, the value of portfolios versus continuing education for competency assessment, evidence associated with portfolio usage, and suggestions for organizing nursing portfolios.

    Full Text Available Long-short strategies are one of the most successful tools, applied by hedge funds manager. One under-evaluated stock is bought (long position and an over-evaluated stock is sold (short position at the same time. After a short term, when the values of the stocks are as expected, profit can be realized by a closing transaction. The possibility to find first obvious over- and under-evaluated stocks depends on the number of participants in this markets. While the hedge funds strategies become more popular, the chance to achieve profit by this strategies is shrinking.Therefore two models to generate long-short portfolios are proposed. By this approaches a portfolio A for the long- and a portfolio B for the short position were computed. The difference of the values of A and B is designed to oscillate from negative to positive and reverse. This behavior of oscillating or mean reverting stock prices was stated by e.g. E. Fama and K. R. French (1988. Mean reversion of portfolios can offer the possibility of statistical arbitrage. The proposed linear models were tested by stocks of the Tokyo stock exchange. The results seem to be applicable and show an additional advantage of low systematic risk.

    Full Text Available The article notes that the task of the investor's risk management is to, on the one hand, as much as possible to strive to achieve the criterion of risk level, and on the other hand, in any case not exceed it. Since the domestic theory of risk management is under development, the problem of the optimal ratio of "risk-income" becomes now of particular relevance. This article discusses the different distribution areas of the private investor in order to obtain the maximum profit. The analysis showed us the overall economic and political system of the country, as well as the legislative provision of guarantees to the investor. To obtain sufficient income and reduce losses it is important to maintain the optimum value found between the amount of the investor's risk and capital transactions. Model of optimal placement of funds led to the conclusion about inexpediency strong increase in the diversification of the investment portfolio (more than 10 different types of assets in the portfolio, since it increases the complexity of its practical form, while the portfolio characteristics are improved significantly. It is concluded that it is impossible to increase revenue without increasing the risk or reduce risk without reducing income. The analysis shows that there is no single best asset portfolio. It is impossible to increase revenue without increasing the risk or reduce risk without reducing income. Possible combination of the "riskincome" will depend on the objective function. Most diversified and bringing the best return per unit of risk, is a portfolio that contains the most risky assets.

    Full Text Available Previous research has shown that links between organizational culture and innovativeness/performance may act as a “social glue” that helps a company develop organizational culture as a competitive advantage. In this study of three case companies, the organizational culture change due business model development projects is studied using the Competing Values Framework (CVF tool and interviews with respondents about discovered changes. To reveal intervention and implied effects between business model development project and organizational culture changes, we used CIMO logic (context, intervention, mechanism, and outcome to bridge practice and theory by explanatory, backward-looking research. Our case studies of companies in relatively short-duration business model development projects indicate that organizational culture may have some dynamic characteristics, for example, an increase of the adhocracy organizational type in all case companies or an increase in the hierarchical leadership type in one case company. Thus, the development of an organizational culture type can be partly controlled. Our results also indicated business model development projects do have a minor effect on organizational culture, even when development activities have not been put fully into practice. However, the more comprehensively business model development project activities have been put into practice, the larger the effect on organizational culture.

    The interest of these six years spent to build the management through the Risks and the Opportunities (R and O) approach on the project Megajoule Laser as well did not hold with the practical application of a method as to the installation of a formal culture and to its evolution in time. This culture, it had to be progressively founded within a mainly technical project team. More qualitative with most quantitative aspects, the putting into practice of the R and O approach on project LMJ knew all the degrees of evolution and precision. The starting of the project saw being born the first analysis of its 'Project Risk' with a series of interviews, carried out by the Quality Manager at the time. This analysis took the shape of a technical item lists, which are identified in an empirical way. Then, some brainstorming meeting were led under the responsibility of the Technical Coordinator (which is the Project Manager assistant) in order to identify and to evaluate the 'Project Risk' on a qualitative way, but always keeping a strong technical connotation. The methodological reference of the 'Project Risk' was outlined taking into account the DGA AQ 923 without directly interaction with the other project processes (for example, the cost, the deadlines and the performance management). Initially, the project developed an Access database, which allows the storing of the risk files. Unfortunately, this database is isolated from the other project management data processing tools. In the second time, the project decided to obtain a dedicated organisation, hierarchically independent from the technical managers but however integrated into the project and attached to the assistant of the Control Project Manager. This organisation being called 'Risks and Opportunities Team', when the management of the opportunities supplemented the R and O approach. This team combines today the individual interviews and the Working Groups in order to identify

    Domestic violence affects women across all racial, national, social, and economic groups. In particular, immigrant and refugee families are at risk for domestic violence because of their migration history and differences in cultural values and norms. The Ahimsa for Safe Families Project is an innovative collaborative project that addresses domestic violence in immigrant and refugee communities in San Diego. The project is designed to increase awareness of domestic violence among Latino, Somali, and Vietnamese communities and to develop and implement culturally specific programs aimed at each community. Here the authors describe the Project's needs assessment and community dialogues that guided the development of specific interventions; present the lessons learned; and describe replicable, culturally specific prevention strategies utilized by the Project.

    Takada, Hellinton H.; Stern, Julio M.

    2017-06-01

    The first portfolio risk diversification strategy was put into practice by the All Weather fund in 1996. The idea of risk diversification is related to the risk contribution of each available asset class or investment factor to the total portfolio risk. The maximum diversification or the risk parity allocation is achieved when the set of risk contributions is given by a uniform distribution. Meucci (2009) introduced the maximization of the Rényi entropy as part of a leverage constrained optimization problem to achieve such diversified risk contributions when dealing with uncorrelated investment factors. A generalization of the risk parity is the risk budgeting when there is a prior for the distribution of the risk contributions. Our contribution is the generalization of the existent optimization frameworks to be able to solve the risk budgeting problem. In addition, our framework does not possess any leverage constraint.

    The Critical Infrastructure Protection Decision Support System--Portfolio Support Tool (CIPDSS-PST) provides a versatile and powerful tool for selecting, optimizing, and analyzing portfolios. The software introduces a compact interface that facilitates problem definition, constraint specification, and portfolio analysis. The tool also provides a simple screen design for comparing user-preferred choices with optimized selections. CIPDSS-PST uses a portable, efficient, mixed-integer optimization engine (lp{_}solve) to derive the optimal mix of projects that satisfies the constraints and maximizes the total portfolio utility. The CIPDSS-PST software can be readily applied to other nonportfolio, resource-constrained optimization problems.

    This article discusses an interdisciplinary research project in which faculty from nursing and english collaborated in the assessment of students' critical thinking skills as reflected in writing portfolios. Faculty reviewed students' writing portfolios and then corresponded on email from two different universities about evidence of critical thinking in the portfolios. Findings suggest that writing portfolios can provide important evidence of critical thinking outcomes. To do this, however, faculty need to design writing assignments to foster critical thinking skills, helping students to think not only about learning to write, but also about using writing to learn.

  3. Approach to assessing local socio-cultural impacts using projections of population growth and composition

    Energy Technology Data Exchange (ETDEWEB)

    Baldwin, T. E.; Poetsch, R.

    1977-08-01

    All assessment of future domestic development projects assumes that the problems to be examined have been properly identified and defined before the application of a projection technique. An attempt is made to codify socio-cultural problems mentioned in literature and clarify how existing demographic projection techniques can be applied to assessing the problems. The relationship between changes in local population size and composition induced by in-migration and the potential for socio-cultural incompatibilities is described heuristically. For simplification, the problems expected to emerge from differences in demographic composition are classified into three categories: (1) service needs, such as those for housing, recreation, and education; (2) types of social organizations related to capacities for, or constraints on, reaping the benefits of rapid economic development and social changes (e.g., employment and income); and (3) attitudes, values, and cultural perspectives. These areas of concern are very broad, and quantitative projections of population size and composition are more easily related to the first than to the third. Although demographic projection provides a valuable tool for estimating future social change, the knowledge about cause and effect is not sufficient to support the quantification of socio-cultural impact. Therefore, the projections are used only as relative indicators and the assessments of socio-cultural impact based on them are qualitative only. Therefore, identification and assessment of socio-cultural impacts are a means of developing plans to overcome the expected problems.

The researchers developed the International Collaborative Project on Cultural Competence (ICPCC to help students understand the impact of cultural context on client care. Entry-level MOT students from a university in the US (N = 18 collaborated with BOT students (N = 4 and advanced MOT students (N = 9 from two universities in India using an online course management system WebCT. The study explored the impact of the ICPCC on OT students’ cultural competence and discusses students’ perceptions of culture on the OT process. The Inventory for Assessing the Process of Cultural Competence Among Health Care Professionals Revised© measured students’ cultural competence at baseline and immediately after participation in the ICPCC. Qualitative data was collected using a Self-Reflection Form. There was an increase in the cultural competence scores among all three groups of students after participating in the ICPCC at p value < .05. Three themes emerged from the qualitative data analysis: meaning of the term culture, impact of cultural on client- centered practice, and impact of cultural on OT outcomes. OT students recognized the role that cultural differences play in OT evaluation and intervention.

    Basidiomycota fungi have received little attention for applications in biocatalysis and biotechnology and remain greatly understudied despite their importance for carbon recycling, ecosystem functioning and medicinal properties. The steady influx of genome data has facilitated detailed studies aimed at understanding the evolution and function of fungal lignocellulose degradation. These studies and recent explorations into the secondary metabolomes have uncovered large portfolios of enzymes useful for biocatalysis and biosynthesis. This review will provide an overview of the biocatalytic repertoires of Basidiomycota characterized to date with the hope of motivation more research into the chemical toolkits of this diverse group of fungi.

    The ever-widening scope and range of global change and interconnected systemic risks arising from people-environment relationships (social-ecological risks) appears to be increasing concern among, and involvement of, citizens in an increasingly diversified number of citizen science projects responding to these risks. We examined the relationship between epistemic cultures in citizen science projects and learning potential related to matters of concern. We then developed a typology of purposes and a citizen science epistemic-cultures heuristic and mapped 56 projects in southern Africa using this framework. The purpose typology represents the range of knowledge-production purposes, ranging from laboratory science to social learning, whereas the epistemic-cultures typology is a relational representation of scientist and citizen participation and their approach to knowledge production. Results showed an iterative relationship between matters of fact and matters of concern across the projects; the nexus of citizens' engagement in knowledge-production activities varied. The knowledge-production purposes informed and shaped the epistemic cultures of all the sampled citizen science projects, which in turn influenced the potential for learning within each project. Through a historical review of 3 phases in a long-term river health-monitoring project, we found that it is possible to evolve the learning curve of citizen science projects. This evolution involved the development of scientific water monitoring tools, the parallel development of pedagogic practices supporting monitoring activities, and situated engagement around matters of concern within social activism leading to learning-led change. We conclude that such evolutionary processes serve to increase potential for learning and are necessary if citizen science is to contribute to wider restructuring of the epistemic culture of science under conditions of expanding social-ecological risk.

    Time Warner Cable (TWC), now Charter Communications (CC), partnered with the National Renewable Energy Laboratory (NREL) to assess the technical and economic potential for solar photovoltaic (PV), wind, and ground-source heat-pump systems at 696 TWC facilities. NREL identified 306 sites where adding a renewable energy system would provide cost savings over the project life-cycle. In general, the top sites have some combination of high electricity rates ($0.16-$0.29/kWh), significant state incentives, and favorable net-metering policies. If all projects were implemented via third-party power purchase agreements, TWC/CC would save $37 million over 25 years and meet 10.5% of their energy consumption with renewable energy. This paper describes the portfolio screening methodology used to identify and prioritize renewable energy opportunities across the TWC sites, as well as a summary of the potential cost savings that may be realized by implementing these projects. This may provide a template for other companies interested in identifying and prioritizing renewable energy opportunities across a large number of geographically dispersed sites. Following this initial portfolio analysis, NREL will be conducting in-depth analysis of project development opportunities at ten sites and evaluating off-grid solutions that may enable carbon emission reduction and grid independence at select facilities.

    The purpose of this article is to describe the process used to create and pilot-test a customized reflective electronic portfolio (e-portfolio) that integrates learning across three distinct components of an entry-level 6.5 year Doctor of Physical Therapy (DPT) program. During the 2004-2005 academic year, a pilot test was conducted with 10 students, representative of all 6.5 years in the DPT program. Development of our reflective e-portfolio model consisted of four stages: design a paper-based portfolio model to organize and create linkages among the liberal studies, professional, and experiential components of a DPT program; transform the model into an electronic format; create a demonstration e-portfolio tutorial; and evaluate the e-portfolio model via pilot testing. An interdepartmental team of faculty from physical therapy (PT), cooperative education, educational technology, and two PT students developed the e-portfolio model to map, visualize, and create linkages for student learning. Input to assist with the model design process was gathered from PT faculty and students through three focus groups. Data were collected on student experiences with the e-portfolio through written surveys at three points during the project and through face-to-face discussion. Written reflection, integral to the model, required students to reflect on artifacts selected from existing academic and experiential materials. Our project resulted in the generation of a reflective e-portfolio and tutorial customized for DPT students. Evaluation by users indicated that the reflective e-portfolio helped them organize and integrate academic and experiential learning and illuminate developmental transitions. Further research with a larger sample is indicated to examine the impact of e-portfolios on student learning and professional development.

  8. Regularizing portfolio optimization

    Still, Susanne; Kondor, Imre

    2010-07-01

    The optimization of large portfolios displays an inherent instability due to estimation error. This poses a fundamental problem, because solutions that are not stable under sample fluctuations may look optimal for a given sample, but are, in effect, very far from optimal with respect to the average risk. In this paper, we approach the problem from the point of view of statistical learning theory. The occurrence of the instability is intimately related to over-fitting, which can be avoided using known regularization methods. We show how regularized portfolio optimization with the expected shortfall as a risk measure is related to support vector regression. The budget constraint dictates a modification. We present the resulting optimization problem and discuss the solution. The L2 norm of the weight vector is used as a regularizer, which corresponds to a diversification 'pressure'. This means that diversification, besides counteracting downward fluctuations in some assets by upward fluctuations in others, is also crucial because it improves the stability of the solution. The approach we provide here allows for the simultaneous treatment of optimization and diversification in one framework that enables the investor to trade off between the two, depending on the size of the available dataset.

  9. The Maslowian Portfolio Theory Versus the Pyramid Portfolio

    Full Text Available This article refers to De Brouwer’s modification of portfolio selection from 2009. He modified the existing portfolio’s theories so that they could take into account the Maslov’s hierarchy of needs. This proposal could be also an alternative concept to the behavioural portfolio theory. Another theoretical concept which includes not only the hierarchy of needs but the pyramid portfolio is presented in this paper as well. The base point in this case is Markowitz’s model and the safety-first criterion by Roy. Such a construction should be a starting point for building an application in this field.

Trata-se de uma atividade que vincula as práticas estratégicas da empresa com a rotina da condução de projetos. Este trabalho tem como objetivo identificar as principais disfunções na implementação da gestão de portfólio nas empresas brasileiras. Essa relação foi estabelecida de forma quantitativa por meio de dados de uma pesquisa do tipo Survey com 45 empresas, pela qual se concluiu que boa parte das organizações utiliza os conceitos de gestão de portfólio, mas com lacunas nos principais processos. Ainda há, portanto, desafios e oportunidades quanto à alocação de recursos para os projetos, à seleção de projetos baseada em poder e quanto à qualidade das informações utilizadas. Esses desafios estão relacionados ao tratamento de projetos por categorias na seleção, às ferramentas utilizadas para priorização, à retroalimentação do resultado dos projetos no planejamento estratégico e à participação da liderança no processo.Project Portfolio Management (PPM is an issue that evolves over time. This activity links strategic activities with the project development routine. The goal of this work is to identify the current state of PPM in Brazilian companies and the relationship between this state and the issues and challenges found. This relationship was established by using the quantitative data of a survey applied to 45 companies, where we could find that most companies are actually using PPM tools. However, there is still some improvement to be made concerning resources allocation, power based project selection, and quality of information used. These challenges are statistically related to the categorization of projects and the selection tools used, to feedback from current projects for strategic planning and senior management participation in the process.

    Ciliberti, S.; Mã©Zard, M.

    2007-05-01

    We use a replica approach to deal with portfolio optimization problems. A given risk measure is minimized using empirical estimates of asset values correlations. We study the phase transition which happens when the time series is too short with respect to the size of the portfolio. We also study the noise sensitivity of portfolio allocation when this transition is approached. We consider explicitely the cases where the absolute deviation and the conditional value-at-risk are chosen as a risk measure. We show how the replica method can study a wide range of risk measures, and deal with various types of time series correlations, including realistic ones with volatility clustering.

    Full Text Available In this paper we exploit the parametric portfolio optimization in the Brazilian market. Our data consists of monthly returns of 306 Brazilian stocks in the period between 2001 and 2013. We tested the model both in and out of sample and compared the results with the value and equal weighted portfolios and with a Markowitz based portfolio. We performed statistical inference in the parametric optimization using bootstrap techniques in order to build the parameters empirical distributions. Our results showed that the parametric optimization is a very efficient technique out of sample. It consistently showed superior results when compared with the VW, EW and Markowitz portfolios even when transaction costs were included. Finally, we consider the parametric approach to be very flexible to the inclusion of constraints in weights, transaction costs and listing and delisting of stocks.

    The goal of this project was to improve unit-based safety culture through implementation of a multidisciplinary (pharmacy, nursing, medicine) teamwork and communication intervention. The Agency for Healthcare Research and Quality Hospital Survey on Patient Safety Culture was used to determine the impact of the training with a before-after design. Surveys were returned from 454 healthcare staff before the training and 368 staff 1 year later. Five of eleven safety culture subscales showed significant improvement. Nurses perceived a stronger safety culture than physicians or pharmacists. While it is difficult to isolate the effects of the team training intervention from other events occurring during the year between training and postevaluation, overall the intervention seems to have improved the safety culture on these medical units.

    Full Text Available Lessons should provide opportunities to use language in relevant ways. Cultural awareness is essential, as studying a language implies learning its cultural values. ACTFL advocates that cultural understanding is vital to prepare students for the demands of today’s globalized world. The U.S. Dept. of Education National Education Technology Plan (2010 claims that learning by technology “prepares them [students] to be more productive members of a globally competitive workforce”(p. xi. In order to promote a communicative experience with a cultural focus, the concepts of collaboration and autonomy were applied in a project where students used a Brazilian website and learned about the importance of a community tradition called Amigo Secreto. Students write personal descriptions and interact online. On the last day of class, students describe their secret friends and the class must guess who they are. The objectives are for students to work collaboratively, use authentic language and improve cultural knowledge.

  14. Time consistent portfolio management

    Ekeland, Ivar; Pirvu, Traian A

    2010-01-01

    This paper considers the portfolio management problem of optimal investment, consumption and life insurance. We are concerned with time inconsistency of optimal strategies. Natural assumptions, like different discount rates for consumption and life insurance, or a time varying aggregation rate lead to time inconsistency. As a consequence, the optimal strategies are not implementable. We focus on hyperbolic discounting, which has received much attention lately, especially in the area of behavioural finance. Following [10], we consider the resulting problem as a leader-follower game between successive selves, each of whom can commit for an infinitesimally small amount of time. We then define policies as subgame perfect equilibrium strategies. Policies are characterized by an integral equation which is shown to have a solution. Although we work on CRRA preference paradigm, our results can be extended for more general preferences as long as the equations admit solutions. Numerical simulations reveal that for the ...

  20. Simple Algorithm Portfolio for SAT

    CERN Document Server

    Nikolic, Mladen; Janicic, Predrag

    2011-01-01

    The importance of algorithm portfolio techniques for SAT has long been noted, and a number of very successful systems have been devised, including the most successful one --- SATzilla. However, all these systems are quite complex (to understand, reimplement, or modify). In this paper we propose a new algorithm portfolio for SAT that is extremely simple, but in the same time so efficient that it outperforms SATzilla. For a new SAT instance to be solved, our portfolio finds its k-nearest neighbors from the training set and invokes a solver that performs the best at those instances. The main distinguishing feature of our algorithm portfolio is the locality of the selection procedure --- the selection of a SAT solver is based only on few instances similar to the input one.

    Toma, Aida; Leoni-Aubin, Samuela

    2015-01-01

    The presence of outliers in financial asset returns is a frequently occurring phenomenon which may lead to unreliable mean-variance optimized portfolios. This fact is due to the unbounded influence that outliers can have on the mean returns and covariance estimators that are inputs in the optimization procedure. In this paper we present robust estimators of mean and covariance matrix obtained by minimizing an empirical version of a pseudodistance between the assumed model and the true model underlying the data. We prove and discuss theoretical properties of these estimators, such as affine equivariance, B-robustness, asymptotic normality and asymptotic relative efficiency. These estimators can be easily used in place of the classical estimators, thereby providing robust optimized portfolios. A Monte Carlo simulation study and applications to real data show the advantages of the proposed approach. We study both in-sample and out-of-sample performance of the proposed robust portfolios comparing them with some other portfolios known in literature.

    电网建设项目组合的投资决策属于多属性决策问题。现有投资决策方法一般将评价指标体系的属性用确定值描述,并对单个项目进行评估得到待选项目集。事实上,有些属性并不适合用确定值来描述;另一方面,有些项目之间存在相关性,这样按单个项目来确定待选项目集就未必合适。在此背景下,首先发展了针对确定型、区间型、概率型和模糊型4种数据类型指标的收益/损失及其概率的计算方法。为计及决策过程中决策者的心理因素和风险倾向的影响,将前景理论引入电网建设项目组合的投资决策之中。然后,基于差异化思想选择指标权重,并利用 VIKOR 这种多准则决策分析方法确定最优项目组合,避免了传统线性加权法用优质指标补偿劣质指标,从而可能导致所得到的最优项目组合中包含劣质指标的情况。最后,以某省级电力公司的电网建设项目组合的投资决策问题为例,说明了所述方法的可行性和有效性。%Determining the most desirable portfolio of construction projects in a power system is a multiple‐attribute decision‐making problem . In traditional portfolio decision‐making methods , the attribute values of indices are described as deterministic ones , and the optimal portfolio is selected from single projects ranked with the attribute values of the indices . However , it is not appropriate to represent some indices as deterministic quantities , and the optimal portfolio should not be selected based on the evaluations of single projects because of the possibility of having correlations among some single projects . Given this background , a method for computing the gains/losses and their probabilities of the indices with deterministic , interval , probabilistic , fuzzy types of data is first developed for the portfolio of construction projects .

    2012-05-01

    Use of electronic portfolios (e-portfolios) has been advocated to demonstrate nursing student accomplishments as well as to document program and course outcomes. This use of e-portfolios incorporates information technology, thus aligning the educational process in professional degree programs to 21st-century teaching and learning scholarship. Here we describe a project to explore the feasibility of transitioning from documenting student competencies in hard-copy binders to e-portfolios. To make this transition in an efficient manner in our graduate nursing program, we used the Plan, Do, Study, Act quality-improvement model. An interdisciplinary team of nursing faculty and educational computing consultants developed a professional e-portfolio template and implemented a pilot program for 10 students enrolled in our nurse educator specialty. This program was executed by assessing university resources, evaluating the technological competence of both students and faculty, and through the interdisciplinary team members' commitment to provide ongoing support for the program.

A etapa de mensuração do risco do investimento abrange diferentes tipos de métricas com impactos diferenciados na escolha do portfólio. Esse trabalho apresenta a metodologia para a seleção de portfólios considerando o semidesvio-padrão como medida de risco. A metodologia é aplicada para um conjunto de seis projetos de produção de petróleo localizados na bacia de Campos, onde é feita a minimização do risco sujeito a um determinado retorno. Como ferramenta de otimização é utilizada a técnica de algoritmos genéticos. A seleção de portfólios foi feita pela maximização do equivalente-certo, para diferentes valores de coeficientes de aversão ao risco. Os resultados mostram que o semidesvio-padrão, apresenta maior sensibilidade na seleção de portfólios com projetos que apresentam grandes magnitudes de risco e retorno.The portfolio selection process for projects involving the exploration and production of oil is a complex task, passing through different steps until and optimum solution is achieved, revealing the best portfolio. This paper presents a methodology for portfolio selection considering semi-standard deviation as a measure of risk. The methodology is applied to a set of six oil production projects located in the Campos Basin, where the risk minimization is subject to a certain return. Genetic algorithms are used as the optimization tool.. The portfolio selection was performed by maximization of the certainty equivalent, for different values of risk aversion coefficients. The results show that the semi-standard deviation presents better sensitivity in portfolio selection with projects that have a large magnitude of risk and return.

    The primary objective of this project is to answer the question: "Can existing, linked infrastructures be used to predict the onset of drought months in advance?" Based on our work, the answer to this question is "yes" with the qualifiers that skill depends on both lead-time and location, and especially with the associated teleconnections (e.g., ENSO, Indian Ocean Dipole) active in a given region season. As part of this work, we successfully developed a prototype drought early warning system based on existing/mature NASA Earth science components including the Goddard Earth Observing System Data Assimilation System Version 5 (GEOS-5) forecasting model, the Land Information System (LIS) land data assimilation software framework, the Catchment Land Surface Model (CLSM), remotely sensed terrestrial water storage from the Gravity Recovery and Climate Experiment (GRACE) and remotely sensed soil moisture products from the Aqua/Advanced Microwave Scanning Radiometer - EOS (AMSR-E). We focused on a single drought year - 2011 - during which major agricultural droughts occurred with devastating impacts in the Texas-Mexico region of North America (TEXMEX) and the Horn of Africa (HOA). Our results demonstrate that GEOS-5 precipitation forecasts show skill globally at 1-month lead, and can show up to 3 months skill regionally in the TEXMEX and HOA areas. Our results also demonstrate that the CLSM soil moisture percentiles are a goof indicator of drought, as compared to the North American Drought Monitor of TEXMEX and a combination of Famine Early Warning Systems Network (FEWS NET) data and Moderate Resolution Imaging Spectrometer (MODIS)'s Normalizing Difference Vegetation Index (NDVI) anomalies over HOA. The data assimilation experiments produced mixed results. GRACE terrestrial water storage (TWS) assimilation was found to significantly improve soil moisture and evapotransportation, as well as drought monitoring via soil moisture percentiles, while AMSR-E soil moisture

    2014-06-01

    Full Text Available The paper proposes the fundamental portfolio of securities. This portfolio is an alternative for the classic Markowitz model, which combines fundamental analysis with portfolio analysis. The method’s main idea is based on the use of the TMAI1 synthetic measure and, in limiting conditions, the use of risk and the portfolio’s rate of return in the objective function. Different variants of fundamental portfolio have been considered under an empirical study. The effectiveness of the proposed solutions has been related to the classic portfolio constructed with the help of the Markowitz model and the WIG20 market index’s rate of return. All portfolios were constructed with data on rates of return for 2005. Their effectiveness in 2006- 2013 was then evaluated. The studied period comprises the end of the bull market, the 2007-2009 crisis, the 2010 bull market and the 2011 crisis. This allows for the evaluation of the solutions’ flexibility in various extreme situations. For the construction of the fundamental portfolio’s objective function and the TMAI, the study made use of financial and economic data on selected indicators retrieved from Notoria Serwis for 2005.

In an effort to introduce BSW students to the socio-political issues facing the local Latino immigrant community, a service-learning project was developed in collaboration with the Spanish Language Department and a local middle school. An analysis of outcomes from social work student evaluations showed that students engaged with the community and issues in new and unexpected ways. Through their engagement in a cross-cultural group project, students developed greater cultural competency, honed their group practice skills in an unfamiliar context, provided a needed service to the community, and raised their awareness about the working conditions of new immigrants as part of a developing framework for social action. Details and implications of the project as a means to build student competencies are described.

    2016-09-01

    Full Text Available While digitalization opens up new possibilities for cultural heritage and tourism it also brings new challenges. Initiatives such as “Europeana”, an internet portal for cultural heritage within the European Union, support institutions with the display of their collections. National initiatives complement these efforts. This report describes initiatives and projects for generating and sustaining digital cultural heritage resources in the German state of Brandenburg. With the cultural heritage distributed throughout the state and managed by hundreds of institutions, the task of digitalization is a common challenge for all of these institutions. Digitalization and digital sustainability is limited by shortcomings in areas of human resources, knowledge and IT infrastructure. In light of these limitations, the cultural heritage community addresses challenges with an interdisciplinary approach. It is based on a collaborative model with four levels: (1 a statewide strategy of an interdisciplinary task force; (2 cooperative projects; (3 cooperative IT infrastructure; and (4 an overall coordination. The priorities are: (1 creating and displaying digital content; (2 establishing best practices and workflows; (3 developing cooperative infrastructures for sustainment. Since 2012, several projects have been implemented based on that collaborative model. More than 50 participating institutions benefited from cooperative planning, managing, digitizing and digital presentation. With regard to the third priority, the task force’s next step is finding solutions for digital preservation. Considering the lack of funding and resources in the cultural heritage sector, options for creating and sustaining digital resources are limited. Digital cultural heritage requires interdisciplinary thinking, cooperative initiatives, reliable IT infrastructures and additional funding.

    The Bregman divergence of two probability vectors is a stronger form of the f-divergence introduced by Csiszar. Two versions of the Bregman universal portfolio are presented by exploiting the mean-value theorem. The explicit form of the Bregman universal portfolio generated by a function of a convex polynomial is derived and studied empirically. This portfolio can be regarded as another generalized of the well-known Helmbold portfolio. By running the portfolios on selected stock-price data sets from the local stock exchange, it is shown that it is possible to increase the wealth of the investor by using the portfolios in investment.

  3. State Clean Energy Practices: Renewable Portfolio Standards

    Energy Technology Data Exchange (ETDEWEB)

    Hurlbut, D.

    2008-07-01

    The State Clean Energy Policies Analysis (SCEPA) project is supported by the Weatherization and Intergovernmental Program within the Department of Energy's Office of Energy Efficiency and Renewable Energy. This project seeks to quantify the impacts of existing state policies, and to identify crucial policy attributes and their potential applicability to other states. The goal is to assist states in determining which clean energy policies or policy portfolios will best accomplish their environmental, economic, and security goals. For example, a renewable portfolio standard (RPS) mandates an increase in the use of wind, solar, biomass, and other alternatives to fossil and nuclear electric generation. This paper provides a summary of the policy objectives that commonly drive the establishment of an RPS, the key issues that states have encountered in implementing an RPS, and the strategies that some of the leading states have followed to address implementation challenges. The factors that help an RPS function best generally have been explored in other analyses. This study complements others by comparing empirical outcomes, and identifying the policies that appear to have the greatest impact on results.

  4. Mitigate cross-cultural pragmatic failure in interpretation with project-based learning

    2012-01-01

    Mistakes in interpretation are concerned with not merely poor language competence but also incapability of smooth crosscultural communication, which indicates that interpreters should be more competent in pragmatics consistent to the cultural models of relevance. The analysis demonstrates the importance of understanding cross-cultural pragmatics and some implications for teaching, particularly in the EIaL environment. Project-based learning, conforming to the requirements of personnel training against the background of globalization, can well serve the goal of developing students' overall cross-cultural communication competence in interpretation courses, when culture and its impacts on pragmatic competence of interpretation are not left out in both the in-class and after-class activities, but are dealt with in a sensitive and open-minded way.

    Full Text Available [english] The use of portfolio offers the possibility to get an overall picture of the learning process and the learning progress. Here, the possibility to learn from experience by self-reflection is in the centre of attention. Depending on the strictness of the given format the rather moderate reliability can be improved significantly. Content validity understood as face validity is guaranteed, while otherwise data on the validity of portfolios are insufficient at the moment. Thus portfolio is a tool, which particularly fits to a formative use (feedback to the students and only with restrictions to the summative assessment of the students' work. It always has to be discussed considering the "teach and learn philosophy" the framing curriculum is based on. Portfolio assessment as such has to be understood (for the moment not as a substitute for traditional assessment formats but as a useful complement in the learning process (of which examinations are an indispensable part.

    Full Text Available The chosen aspects and assumptions of the author’s proposal of the optimization model of the non-profit projects’ portfolio are presented. The functional model of the non-profit sector (third sector, which is the base for the further analyses, is also characterized. The article also contains the quantification of fundamental conditions of portfolio optimization. There is developed the utility model for the management system in the non-profit portfolio, in the framework of which there are specified the scope of the model and relationships between four categories of the non-profit portfolio’s participants/stakeholders: non-profit organizations, donors, co-participants and customers (recipients of the basic benefits/values associated with the realization of the non-profit projects. The main optimality conditions and optimization algorithm of the non-profit portfolio are also given. The paper is concluded with exemplary analytical matrixes used for optimization of the non-profit portfolios and based on the evaluation of both the optimization utility conditions and added parameters. Only basic and chosen aspects of the optimization of the non-profit projects’ portfolio have been described here.

  9. Risks of Large Portfolios.

    Fan, Jianqing; Liao, Yuan; Shi, Xiaofeng

    2015-06-01

    The risk of a large portfolio is often estimated by substituting a good estimator of the volatility matrix. However, the accuracy of such a risk estimator is largely unknown. We study factor-based risk estimators under a large amount of assets, and introduce a high-confidence level upper bound (H-CLUB) to assess the estimation. The H-CLUB is constructed using the confidence interval of risk estimators with either known or unknown factors. We derive the limiting distribution of the estimated risks in high dimensionality. We find that when the dimension is large, the factor-based risk estimators have the same asymptotic variance no matter whether the factors are known or not, which is slightly smaller than that of the sample covariance-based estimator. Numerically, H-CLUB outperforms the traditional crude bounds, and provides an insightful risk assessment. In addition, our simulated results quantify the relative error in the risk estimation, which is usually negligible using 3-month daily data.

    2016-06-01

    Investors wish to achieve the target rate of return at the minimum level of risk in their investment. Portfolio optimization is an investment strategy that can be used to minimize the portfolio risk and can achieve the target rate of return. The mean-variance model has been proposed in portfolio optimization. The mean-variance model is an optimization model that aims to minimize the portfolio risk which is the portfolio variance. The objective of this study is to construct the optimal portfolio using the mean-variance model. The data of this study consists of weekly returns of 20 component stocks of FTSE Bursa Malaysia Kuala Lumpur Composite Index (FBMKLCI). The results of this study show that the portfolio composition of the stocks is different. Moreover, investors can get the return at minimum level of risk with the constructed optimal mean-variance portfolio.

    Full Text Available The purpose of the following study is to evaluate the degree of satisfaction with the online portfolio as a resource for assessing the initial teaching performance of students preparing at the Catholic University of Temuco, Chile, to become primary school teachers. Two groups were used in this research: an experimental one that worked with the online portfolio, and a control group that worked with the physical file. The sample consisted of 30 students randomly selected from the fourth year of the program. The level of satisfaction expressed by users of the portfolio was evaluated at the end of the practice-teaching experience. In order to take this measurement, an instrument called a semantic differential was especially designed for the purpose. The experimental group showed a difference significantly greater than that of the control group in the variable degree of satisfaction with the portfolio tool. Also, a positive and significant correlation was observed between the degree of satisfaction expressed by the students, and the score obtained by them in the initial-teaching-performance portfolio.

    The problem of portfolio optimization is one of the most important issues in asset management. We here propose a new dynamic portfolio strategy based on the time-varying structures of MST networks in Chinese stock markets, where the market condition is further considered when using the optimal portfolios for investment. A portfolio strategy comprises two stages: First, select the portfolios by choosing central and peripheral stocks in the selection horizon using five topological parameters, namely degree, betweenness centrality, distance on degree criterion, distance on correlation criterion and distance on distance criterion. Second, use the portfolios for investment in the investment horizon. The optimal portfolio is chosen by comparing central and peripheral portfolios under different combinations of market conditions in the selection and investment horizons. Market conditions in our paper are identified by the ratios of the number of trading days with rising index to the total number of trading days, or the sum of the amplitudes of the trading days with rising index to the sum of the amplitudes of the total trading days. We find that central portfolios outperform peripheral portfolios when the market is under a drawup condition, or when the market is stable or drawup in the selection horizon and is under a stable condition in the investment horizon. We also find that peripheral portfolios gain more than central portfolios when the market is stable in the selection horizon and is drawdown in the investment horizon. Empirical tests are carried out based on the optimal portfolio strategy. Among all possible optimal portfolio strategies based on different parameters to select portfolios and different criteria to identify market conditions, 65% of our optimal portfolio strategies outperform the random strategy for the Shanghai A-Share market while the proportion is 70% for the Shenzhen A-Share market.

    Tangible cultural heritage includes various categories of monuments and sites, from cultural landscapes and sacred sites to archaeological complexes, individual architectural or artistic monuments and historic urban centers. Such places are continuously impacted and weathered by several internal and external factors, both natural and human-induced, with rapid and/or slow onset, including natural hazards, such as earthquakes or extreme meteorological events, cumulative processes as well as the effects of humans, especially in conflict situations. A clear picture of endangered sites is not available. In particular, the list of List of World Heritage in danger mainly focuses on sites threaten by armed conflicts. New space technology based on radar interferometry (InSAR) is now capable to monitor, since 1992 and with mm precision, surface deformation for reflective targets named persistent scatterers, which consistently return stable signals to the radar satellites. Led by the Italian Institute for Environmental Protection and Research, and in collaboration with NERC British Geological Survey, Geological and Mining Institute of Spain, University of Milano-Bicocca and Cyprus University of Technology, the project PROTHEGO, co-funded in the framework of JPI on Cultural Heritage EU programme (2015-2018), will make an innovative contribution towards the analysis of geo-hazards in areas of cultural heritage in Europe. The project will apply novel InSAR techniques to monitor monuments and sites that are potentially unstable due to landslides, sinkholes, settlement, subsidence, active tectonics as well as structural deformation, all of which could be effected of climate change and human interaction. To magnify the impact of the project, the approach will be implemented in more than 400 sites on the UNESCO World Heritage List in geographical Europe.

    The acquisition and divestiture of organizational business units demonstrate management's strategy in response to an evolving marketplace. From a strategic perspective, the most significant danger to a corporation is not having the "right" portfolio of businesses or products to respond to the marketplace. This article describes a conceptual model that a multihospital system executive might use to determine the growth and diversification of the organization's portfolio of businesses. The model involves the application of market, financial, and microeconomic theories in a logical sequence to assist management in making business acquisition and divestiture decisions.

    Mentoring in rural and remote nursing receives little attention in the literature, even though it is emerging in Australia as a popular strategy to improve the retention of staff. The Association for Australian Rural Nurses established a 2-year Mentor Development and Support Project in 2003 with the aim of promoting mentoring among rural and remote nurses. During the life of the project, 101 such nurses attended Mentor Development Workshops. This project demonstrated that training is an important prerequisite for rural and remote nurses who are planning to enter a mentoring relationship. Participant evaluation showed an increase in mentoring knowledge and skills and a subsequent rise in confidence about undertaking the role. Participants also believed that their increased capacity to mentor was reflected in their workplaces, contributing to a positive culture of learning.

  10. The modern portfolio theory applied to wind farm financing

    Energy Technology Data Exchange (ETDEWEB)

    Chaves-Schwinteck, P. [DEWI GmbH, Oldenburg (Germany)

    2011-02-15

    An alternative to the application of the principles of the Modern Portfolio Theory as a strategy to the reduction of the risks around the energy production of wind farms was presented in the last sections. The potential of geographical diversification to reduce the risks related to the availability of wind as a primary resource was demonstrated by the results of the first case study. Furthermore, the results of the second case study have shown that, once a sufficient history of technical performance data is available, a reduction of the risks linked to the technical performance of the wind turbines can be achieved in a similar way. Nevertheless, the existence of 'non-diversifiable' risks still presents a challenge for the financing of wind farms. In this sense, it is important to point out that the financing performance of a portfolio of wind farms is extremely dependent on the individual performance of the single projects. In other words, a portfolio analysis is not a miracle. A 'bad' project remains a 'bad' project even when this project is bundled with a 'good' one. For this reason, other risk management strategies, as for example, a well performed technical due diligence should be always taken into consideration. (orig.)

  11. Entropy-based portfolio models: Practical issues

    Entropy is a nonparametric alternative of variance and has been used as a measure of risk in portfolio analysis. In this paper, the computation of entropy risk for a given set of data is discussed with illustration. A comparison between entropy-based portfolio models is made. We propose a natural extension of the mean entropy portfolio to make it more general and diversified. In terms of performance, this new model is similar to the mean-entropy portfolio when applied to real and simulated data, and offers higher return if no constraint is set for the desired return; also it is found to be the most diversified portfolio model.

    The universal portfolio is an important investment strategy in a stock market where no stochastic model is assumed for the stock prices. The zero-gradient set of the objective function estimating the next-day portfolio which contains the reverse Kullback-Leibler order-alpha divergence is considered. From the zero-gradient set, the explicit, reverse Helmbold universal portfolio is obtained. The performance of the explicit, reverse Helmbold universal portfolio is studied by running them on some stock-price data sets from the local stock exchange. It is possible to increase the wealth of the investor by using these portfolios in investment.

    Full Text Available This study focuses on the assessment of speaking skills with reference to young learners. This is achieved by using an alternative method of assessment, namely portfolios. The general aim is to introduce learners’ to portfolio assessment of their speaking skills and to promote further learning and autonomy making, thus, learning and assessment coexist in a non-threatening mode. Three methodological tools are used for this research; a needs analysis questionnaire addressing the pupils��� needs of the fifth grade of a Greek primary school, the European Portfolio of Languages (ELP - used in tandem with the oral portfolio Dossier - and a final evaluation questionnaire given to the pupils after the completion of the oral portfolio project. Based on the statistical analysis of pupils’ evaluation results and the teacher’s observation throughout the school year, it is evident that the oral portfolio denotes a time-consuming and laborious assessment process. Nevertheless, the pupils see it as an interesting experience and are willing to use it again in the future. In conclusion, students’ portfolios are an innovative method of assessment that can actually promote the development of speaking skills and young learners’ metacognitive strategies in the EFL classroom, and raise their interest in learning.

    Full Text Available This study examines the effect of Islamic screening criteria on Shari’ah-compliant portfolio selection and performance compared to Socially Responsible Investment (SRI portfolio. Each portfolio constructed from 15 stocks based on FTSE 100 using data from year 1997. Mean-variance portfolio optimization is employed with some financial ratios added as constraints for the Shari’ah portfolio. Annual expected return of each portfolio from 2008 to 2013 is used to calculate Sharpe’s ratio, Treynor ratio and Jensen’s alpha as the performance measurement tools. Macroeconomic variables are assessed using ordinary least square to examine whether they influence the portfolios’ expected returns or not. The result finds that Shari’ah portfolio has a better performance than SRI from year 2008 to 2010 shown by higher value of the measurement tools. However, from 2011 to 2013, SRI portfolio has better performance than Shari’ah portfolio

    Full Text Available Every year an increasing number of employers get interested in the university graduates, most suitable for the requirements the companies set. However, the standard CVs often do not reveal the potential and peculiarities of formation of graduate competences. The authors suggest using portfolio instead of a CV. The authors analyzed 1797 portfolios of TPU students and offered optimal structure and criteria of portfolio. In addition, the authors provide an example of how the achievements reflected in portfolio can be considered. The conclusion is made about the necessity of the portfolio. The authors determined employer’s role in the formation and evaluation of the portfolio. Moreover, the value of tracking the dynamics of growth of portfolio components is denoted as a new performance evaluation system in higher education.

  5. Robust Portfolio Optimization Using Pseudodistances

    Science.gov (United States)

    2015-01-01

    The presence of outliers in financial asset returns is a frequently occurring phenomenon which may lead to unreliable mean-variance optimized portfolios. This fact is due to the unbounded influence that outliers can have on the mean returns and covariance estimators that are inputs in the optimization procedure. In this paper we present robust estimators of mean and covariance matrix obtained by minimizing an empirical version of a pseudodistance between the assumed model and the true model underlying the data. We prove and discuss theoretical properties of these estimators, such as affine equivariance, B-robustness, asymptotic normality and asymptotic relative efficiency. These estimators can be easily used in place of the classical estimators, thereby providing robust optimized portfolios. A Monte Carlo simulation study and applications to real data show the advantages of the proposed approach. We study both in-sample and out-of-sample performance of the proposed robust portfolios comparing them with some other portfolios known in literature. PMID:26468948

    2004-10-01

    In 1997 the Royal College of Paediatrics and Child Health introduced portfolios to guide and monitor the learning of specialist registrars. We studied their value for assessment. Using Bigg's SOLO criteria we devised a marking scheme based on 6 domains of competence: clinical, communication, teaching and learning, ethics and attitudes, management and evaluation, and creation of evidence. We rated portfolios according to quality of evidence presented and expectations by year of training. We similarly assessed trainee performance in the annual record of in-training assessment (RITA) interview. Specific advice based on the results of the first portfolio assessments was circulated to all trainees, instructing them to increase the structure and decrease the bulk of portfolios. A second sample of portfolios was reviewed a year later, using similar evaluations, to determine the effects. A total of 76 portfolios were assessed in year 1 by a single rater; 30 portfolios were assessed in year 2 by 2 independent raters. The quality of documentation improved from year 1 to year 2 but there was no significant increase in portfolio scores. The inter-rater correlation coefficient of the portfolio assessment method was 0.52 (Cohen's kappa 0.35). The inter-rater correlation coefficient of the RITA interview was 0.71 (Cohen's kappa 0.38). There was moderate inter-assessment correlation between portfolios and RITA interviews (kappa 0.26 in year 1 and 0.29 in year 2). Generalisability analysis suggested that 5 successive ratings by a single observer or independent ratings by 4 observers on the same occasion would be needed to yield a generalisability coefficient > 0.8 for overall portfolio rating. This method of portfolio assessment is insufficiently reliable as a sole method for high stakes, single-instance assessment, but has a place as part of a triangulation process. Repeated portfolio assessment by paired observers would increase reliability. Longer term studies are required to

  13. Domesticating Hybridity: Straits Chinese Cultural Heritage Projects in Malaysia and Singapore

    2015-12-01

    Full Text Available This article examines the literal and figurative domestication of Straits Chinese, or Peranakan, history in selected heritage projects in late twentieth-century Malaysia and Singapore. These projects simultaneously foreground Straits Chinese history as a symbol of interracial harmony and marginalize it as a cultural artifact. Over the late nineteenth and twentieth centuries, the ethnoculturally hybrid Straits Chinese positioned themselves as “the King’s Chinese,” champions of a Confucian-values renaissance, and citizens of independent Malaysia and Singapore. Their adaptability helped them survive the upheaval of imperialism, decolonization, and nation building, but it was also controversial for its suggestion of political flexibility. Today, Southeast Asian governments and the Peranakan themselves depict the community as a uniquely local model of ethnic integration. Museums and historic homes emphasize portrayals and consumption of supposedly feminine aspects of Peranakan culture (e.g., fashion and cuisine, while downplaying purportedly masculine elements (e.g., the possession of multiple nationalities. By conflating femininity, tradition, and racial hybridity, this approach reifies stereotypes about gender and cultural identity, and replaces transgressive potential with politically anodyne nostalgia and commercialization. As anxieties about race, national history, and belonging continue to undergird the modern polity, transnationalism and transculturalism are acceptable as long as they are confined to the past.

    Full Text Available The practice of digitizing cultural heritage sites is gaining ground among conservation scientists and scholars in architecture, art history, computer science, and related fields. Recently, the location of such sites in areas of intense conflict has highlighted the urgent need for documenting cultural heritage for the purposes of preservation and posterity. The complex histories of such sites requires more than just their digitization, and should also include the meaningful interpretation of buildings and their surroundings with respect to context and intangible values. Project Anqa is an interdisciplinary and multi-partner effort that goes beyond simple digitization to record at-risk heritage sites throughout the Middle East and Saharan Africa, most notably in Syria and Iraq, before they are altered or destroyed. Through a collaborative process, Anqa assembles documentation, historically contextualizes it, and makes data accessible and useful for scholars, peers, and the wider public through state-of-the-art tools.

    In recent years, some workshops and research cases have arisen in China to seek for suitable ways for heritage conservation and development of historic villages. However, the issue of multi-cooperation has not been much mentioned in research works. The case of Cangdong Project in Guangdong Province is a social enterprise. It is a center focusing on heritage education. It organizes tailor-made workshops for interested people from all over China and Hong Kong, Macao and overseas, including university courses for credits, summer/winter camps for primary and middle school students, as well as common people who are interested in heritage conservation. The purpose of the education center is to enhance heritage/cultural interest of the younger generations and common people, and try to work with local villagers to build a wealthy community. Nowadays, more and more villagers moved out for work and the countryside population in China is decreasing, this project also aims to create work opportunities for villagers through heritage conservation projects, so that the villagers can be willing to stay. The project focuses more in a sustainable way for community development. It has been five years since the project was set up in Cangdong Village. The project team worked with villagers, city people, students, scholars, different levels of local governments, investors, Medias, charitable organizations, as well as the market of tourism. As such, a platform of multi-cooperation for the above parties has formed during the past five years. This paper takes the Project experience from 2010-2015 as the case to study multi-cooperation in the field of heritage conservation in China, as well as to discuss how to co-operate the subjective initiatives of different stokeholds.

Most of the existing web-based platforms are using WebGL technology to disseminate 3D content through Web navigators, despite they are normally generic, with a low level of viewers ‘customization. Alternatively, users can make use of several libraries, most of them open source, which allow a complete adaptation to the specific project features, even though enough level of programming skills are necessary to use them. In the present paper we will describe the minimum requirements that any cultural heritage dissemination project should contain and its implementation using Three-js, one of the most versatile open source libraries for 3D visualization. In addition, we will show several examples of Three-js integration with other libraries that take advantage from HTML5 (HyperText Markup Language, version 5 to enhance the user's experience on a Web platform.

    The purpose of this literature review is to explore the value of portfolio building and the registered nurse under the following themes: assessment of competence; work-based reflection; lifelong learning; creating career pathways and the contribution a portfolio makes to the professional development of the nurse. This review concludes that for portfolios to work effectively, nurses and their employers require a working partnership to see the value and the opportunities that exist through the development of a personal portfolio. The need exists for an organisational culture of learning that encourages a facilitative environment combined with nurses who support their colleagues and explore their skills through experiential learning. This work was submitted in part fulfilment for the Degree of Master of Science in Nursing at Queen's University of Belfast, School of Nursing and Midwifery in 2007 and was supported by ERFF.

  19. Applying Portfolio Theory to EU Electricity Planning and Policy-Making

    Awerbuch, Shimon; Berger, Martin

    2003-02-01

    This study introduces mean-variance portfolio theory and evaluates its potential application to the development of efficient (optimal) European Union (EU-15) generating portfolios that enhance energy security and diversification objectives. The analysis extends to European countries the previous work done by Awerbuch in the US, and applies a significantly more detailed portfolio model that reflects the risk of the relevant generating cost streams: fuel, operation and maintenance and construction period costs. It illustrates the portfolio effects of different generating mixes. The study offers preliminary findings on the effects of including more renewable energy sources in the typical EU portfolio mix and suggests interesting directions for further study. The study arises from the perception that these standard, finance-oriented analyses may offer valuable enhancements to energy planning, and concepts of energy security and diversity. Clearly the combination of better portfolio construction and more accurate pricing should lead to more optimal decisions in the round. This study, therefore, represents an effort to complement traditional approaches and point researchers and planners into new territory. The results generally indicate that the existing and projected EU generating mixes are sub optimal - though slightly - from a risk-return perspective, which implies that feasible portfolios with lower cost and risk exist. These can be developed by adjusting the conventional mix and by including larger shares of wind or similar renewable technologies. The results of the portfolio analysis suggest that fixed cost technologies such as renewables must be a part of any efficient generating portfolio. Our assessment of all technologies is limited to risk and cost measures, although other benefits, including low externality costs and sustainability, are often cited for renewables.
