  2. Intangible Benefits Quantified: Insights from Micro-level Return on Investment Case Studies

    NASA Astrophysics Data System (ADS)

    Stewart, M. A.

    2013-12-01

    This presentation addresses the question: must socio-economic benefits of geospatial projects be considered intangible and thus unquantifiable? The question will be answered from the perspective of an engineer and geospatial practitioner, with examples provided from case studies using micro level financial analysis. Topics will include: 1. Quantification as a tool for setting and achieving goals, illustrated with individual and societal uses of measurement. 2. Geospatial data as a driver for economic and social development. 3. Building use cases from documented work processes, demographic information and external research results. 4. Moving beyond GDP to quantify the well being of individuals and society. 5. Extrapolation of case study results to quantify a technology's current and potential return on investment to society. 6. Is it realistic for society to work toward commonly held measurements of well being? Or should individual cases maintain uniquely developed measurements to more accurately characterize their results?

  3. Social return of R&D investments in manufacturing sector: Some insights from an exploratory case study

    2012-04-01

    This paper aims at contributing to the literature on how to measure the social impact of Research and Development (R&D) investment projects. For that purpose, an exploratory case study was undertaken to assess the importance that companies give to the social return of R&D investments and to identify the criteria and indicators more relevant for this evaluation process. The research undertaken is based on interviews conducted as part of a case study methodology involving a maritime-sector private company and the Technological Center of the Sea in Vigo. The results indicate that the criteria chosen as being the most important for the evaluation of social return of R&D were the number of jobs created at the company, the environmental impact and the working conditions. Also, in the case of Support Programs for R&D applications funding the research results indicate that the evaluation process presently followed does not properly address the socio-economic factors.

    There are insufficient resources available to manage the world's existing protected area portfolio effectively, so the most important sites should be prioritised in investment decision-making. Sophisticated conservation planning and assessment tools developed to identify locations for new protected areas can provide an evidence base for such prioritisations, yet decision-makers in many countries lack the institutional support and necessary capacity to use the associated software. As such, simple heuristic approaches such as species richness or number of threatened species are generally adopted to inform prioritisation decisions. However, their performance has never been tested. Using the reptile fauna of Madagascar's dry forests as a case study, we evaluate the performance of four site prioritisation protocols used to rank the conservation value of 22 established and candidate protected areas. We compare the results to a benchmark produced by the widely-used systematic conservation planning software Zonation. The four indices scored sites on the basis of: i) species richness; ii) an index based on species' Red List status; iii) irreplaceability (a key metric in systematic conservation planning); and, iv) a novel Conservation Value Index (CVI), which incorporates species-level information on endemism, representation in the protected area system, tolerance of habitat degradation and hunting/collection pressure. Rankings produced by the four protocols were positively correlated to the results of Zonation, particularly amongst high-scoring sites, but CVI and Irreplaceability performed better than Species Richness and the Red List Index. Given the technological capacity constraints experienced by decision-makers in the developing world, our findings suggest that heuristic metrics can represent a useful alternative to more sophisticated analyses, especially when they integrate species-specific information related to extinction risk. However, this can require access to

    Coordinated and organized by a disabilities librarian, the University of Michigan's Council for Disability Concerns provides annual outreach programs with biomedical themes through a series of educational events known as Investing in Ability. Every effort is made to reach the campus and the surrounding community to promote the council's goals of increased accessibility for all individuals with physical or developmental challenges, to de-stigmatize such conditions, and to educate the audience about disability-related topics. In 2014, Investing in Ability focused on the pressing and pervasive topic of addiction. Because audience attendance and interest were the highest that they have ever been for previous Investing in Ability events, the project will serve as a model in the future, possibly as one for other committees to emulate.

    The World Resources Institute (WRI), in cooperation with multi- and bi-lateral organizations, has launched a major initiative to conserve forests in the humid and semiarid/arid areas of developing countries. The 3-part WRI report is a call to political action on this subject. Part 1 describes the high costs exacted by deforestation, but asserts that the process can be arrested and reversed by a partnership of governments, local participants, and development-assistance agencies. Proposals are presented for a 5-year action plan in farm, community, and arid-zone forestry. Parts 2 and 3 include case studies of the successful projects listed in Part 1 and 5-year investment profiles of 56 developing countries affected by deforestation.

    Over the last several years, many U.S. states have established clean energy funds to help support the growth of renewable energy markets. Most often funded by system-benefits charges (SBC), the 15 states that have established such funds are slated to collect nearly $3.5 billion from 1998 to 2012 for renewable energy investments. These clean energy funds are expected to have a sizable impact on the energy future of the states in which the funds are being collected and used. For many of the organizations tapped to administer these funds, however, this is a relatively new role that presents the challenge of using public funds in the most effective and innovative fashion possible. Fortunately, each state is not alone in its efforts; many other U.S. states and a number of countries are undertaking similar efforts. Early lessons are beginning to be learned by clean energy funds about how to effectively target public funds towards creating and building renewable energy markets. A number of innovative programs have already been developed that show significant leadership by U.S. states in supporting renewable energy. It is important that clean energy fund administrators learn from this emerging experience.

    2013-12-01

    Federally funded scientific research is one of the building blocks of technological advancement and economic growth. This research can also lead to transformational ideas and discoveries. In our current fiscal environment, strategies to rein in federal spending have become a priority, although they have proven to be complex. The possible deals and negotiations to reduce federal spending may hinder the work of the scientific community to serve society. Since 2005 federal investment in research and development has slowed. The average annual growth in federal funding for scientific research from 2004 - 2009 was 0.9% as compared to 3.3% over the previous 20 years. What does the current budget situation mean for science? It means reductions in basic and applied research, interruptions in long-term monitoring and data collection, an inability to repair or build infrastructure, and less federal grant support for current and future scientists. I will first provide an update on the current federal budget situation and examples of how current policies are impacting the scientific community. Second, I will present a case study of the effect of reduced federal investment in science. Specifically, I will discuss how investments in research and development have far-reaching impacts on society and examine how reduced funding impairs valuable research efforts.

    We review strategic approaches taken over an eight-year period at BMS to implement new high-throughput approaches to lead discovery. Investments in compound management infrastructure and chemistry library production capability allowed significant growth in the size, diversity and quality of the BMS compound collection. Screening platforms were upgraded with robust automated technology to support miniaturized assay formats, while workflows and information handling technologies were streamlined for improved performance. These technology changes drove the need for a supporting organization in which critical engineering, informatics and scientific skills were more strongly represented. Taken together, these investments led to significant improvements in speed and productivity as well a greater impact of screening campaigns on the initiation of new drug discovery programs.

  2. Foreign direct investment strategies: Least-developed countries and foreign firms. A case study of Sudan and Chevron Oil

    The least-developed countries (LDCS) are politically underdeveloped. They often have autocratic authoritarian regimes that give less than appropriate attention to their societies' development. Being vulnerable and fairly unstable, such regimes are more occupied with their own survival than with developing pragmatic plans that cater to supplying their nations with missing economic resources needed through Foreign Direct Investment (FDI). Internal and external pressures on LDCS with such primitive political structures have greatly confused their leaderships and have resulted in the lack of institutionalization in these countries. Foreign firms normally choose to serve world markets through direct operations rather than exporting or licensing because the former maximize their gains more than the two other alternatives. This is why benefits to host countries may not match a host country's expectations when it allows FDI penetration. It is the contention of this research that Sudan failed to formulate a right policy towards FDI, and came short of maximizing its scarce resource returns. On the other hand, Chevron Oil, with a global overall profit-maximization strategy, succeeded in running its subsidiary in Sudan in accordance with its global outlook.

A methodological challenge of eradication investment cases is how to account for the ethical importance of the benefits, burdens, and distributions thereof that are salient in people's experiences of the diseases and related interventions but are not assessed in traditional approaches to health and economic evaluation. We have offered a method of ethical analysis grounded in theories of social justice. We have described the method and its philosophical rationale and illustrated its use in application to eradication investment cases for lymphatic filariasis and onchocerciasis, 2 neglected tropical diseases that are candidates for eradication.

    1991-01-01

    Spiraling costs of medical care services and limited federal and state resources necessitate discriminating and cost-effective strategies for financing health care to indigent populations. Thus, while the selection among intervention strategies is aided by information on both the cost and benefits of program alternatives, data on the latter aspect is more difficult to obtain. Human capital research provides a mechanism for assessing one of the multifarious aspects of the benefits of medical services. Research suggests that labor market earnings opportunities are affected by health status. The present study explores this relationship for migrant farmworkers in a vegetable production county (Orange County) in upstate New York. Multivariate analysis indicated that mental well-being was an important predictor of earnings for migrant farmworkers. Directions for public health policy intervention strategies are also discussed.

    2015-08-15

    There is a growing call for ecosystem services models that are both simple and scientifically credible, in order to serve public and private sector decision-making processes. Sediment retention receives particular interest given the impact of this service on water quality. We developed a new version of the sediment retention model for the InVEST (Integrated Valuation of Environmental Services and Tradeoffs) tool to address previous limitations and facilitate model uncertainty assessment. We tested the model in the Cape Fear basin, North Carolina (NC), performing sensitivity analyses and assessing its ability to detect the spatial variability in sediment retention service for eight subcatchments. The main advantages of the revised model include the use of spatially-explicit, globally available input data, and the explicit consideration of hydrological connectivity in the landscape. The sensitivity analyses in the study catchment identified the erosivity and erodibility factors, together with the cover factor for agricultural land as the most influential parameter for sediment export. Relative predictions, representing the spatial variability in sediment exports, were correctly represented by the model. Absolute sediment exports were also highly correlated with observations, although their interpretation for socio-economic assessments is more uncertain without local knowledge of the dominant erosion processes. This work confirms that the sediment connectivity approach used in the revised InVEST model has great potential to quantify the sediment retention service. Although resources to conduct model calibration and testing are typically scarce, these practices should be encouraged to improve model interpretation and for confident application in different decision-making contexts. Without calibration, the InVEST sediment model still provides relevant information for ecosystem services assessments, especially in decision contexts that involve ranking of sediment export

    with respect to land rents, and the elasticity of substitution between land and non-land inputs. For assessing the mitigation costs, the elasticity of productivity with respect to investments in research and development is also very important. Overall, this study finds that broad-based efforts to adapt agriculture to climate change have mitigation co-benefits that, even when forced to shoulder the entire expense of adaptation, are inexpensive relative to many activities whose main purpose is mitigation. These results therefore challenge the current approach of most climate financing portfolios, which support adaptation from funds completely separate from—and often much smaller than—mitigation ones.

    In 1999, the Blue Cross and Blue Shield Federal Employee Program (FEP) implemented a pilot disease management program to manage congestive heart failure (CHF) among members. The purpose of this project was to estimate the financial return on investment in the pilot CHF program, prior to a full program rollout. A cohort of 457 participants from the state of Maryland was matched to a cohort of 803 nonparticipants from a neighboring state where the CHF program was not offered. Each cohort was followed for 12 months before the program began and 12 months afterward. The outcome measures of primary interest were the differences over time in medical care expenditures paid by FEP and by all payers. Independent variables included indicators of program participation, type of heart disease, comorbidity measures, and demographics. From the perspective of the funding organization (FEP), the estimated return on investment for the pilot CHF disease management program was a savings of $1.08 in medical expenditure for every dollar spent on the program. Adding savings to other payers as well, the return on investment was a savings of $1.15 in medical expenditures per dollar spent on the program. The amount of savings depended upon CHF risk levels. The value of a pilot initiative and evaluation is that lessons for larger-scale efforts can be learned prior to full-scale rollout.

    2011-01-01

    Least terns (Sternula antillarum) are threatened by rapid human development on the northern coast of Sonora, Mexico. Terns are bellwethers for changes along the world's coastlines, as their coastal breeding habitat is vulnerable to flooding and development. We conducted targeted ground and aerial surveys for least tern colonies along 160 kilometers of coast, and document our findings on colony sizes at nine sites over 3 years in the first portion of this report. Like many taxa, terns lay larger clutches at higher latitudes. In the second portion of this report, we evaluate least tern breeding lifespan, food availability, and nest predation as potential ecological reasons behind this differing clutch-size pattern. After correcting for phylogenetic relationships, we found that food availability, not breeding lifespan or nest predation rate, was related to reproductive investment across 46 species and populations of terns. We conclude that coastal development may have a greater impact on nesting terns in tropical regions as compared to temperate breeding locations, because global oceanic patterns of decreased food availability reduce reproductive investment in the tropics.

    Stage financing is the basic operation of venture capital investment. In investment, usually venture capitalists use different strategies to obtain the maximum returns. Due to its advantages to reduce the information asymmetry and agency cost, stage financing is widely used by venture capitalists. Although considerable attentions are devoted to stage financing, very little is known about the risk aversion strategies of IT projects. This paper mainly addresses the problem of risk aversion of venture capital investment in IT projects. Based on the analysis of characteristics of venture capital investment of IT projects, this paper introduces a real option pricing model to measure the value brought by the stage financing strategy and design a risk aversion model for IT projects. Because real option pricing method regards investment activity as contingent decision, it helps to make judgment on the management flexibility of IT projects and then make a more reasonable evaluation about the IT programs. Lastly by being applied to a real case, it further illustrates the effectiveness and feasibility of the model.

    Stage financing is the basic operation of venture capital investment. In investment, usually venture capitalists use different strategies to obtain the maximum returns. Due to its advantages to reduce the information asymmetry and agency cost, stage financing is widely used by venture capitalists. Although considerable attentions are devoted to stage financing, very little is known about the risk aversion strategies of IT projects. This paper mainly addresses the problem of risk aversion of venture capital investment in IT projects. Based on the analysis of characteristics of venture capital investment of IT projects, this paper introduces a real option pricing model to measure the value brought by the stage financing strategy and design a risk aversion model for IT projects. Because real option pricing method regards investment activity as contingent decision, it helps to make judgment on the management flexibility of IT projects and then make a more reasonable evaluation about the IT programs.

    Marson, G K

    2001-12-01

    This paper introduces the problems facing occupational health departments in the current environment created by new legislation and changes in social attitudes. The problems of establishing the true costs and benefits of service provision are discussed. The paper also explains the employment of the 'value principle' in organizations and postulates its use in order to establish the appropriate position of occupational health in corporate thinking. A practical system is suggested, based on a four-step process of strategic planning, issues development, option establishment and plan implementation, which can be used to evaluate and justify investment in services. The problems of future risk are addressed. The paper concludes with the priority of establishing the strategic importance of occupational health services alongside other personnel issues and expresses the possibility of using the same principles outside the business world.

    Globally, tobacco kills more people than HIV-related conditions or AIDS, tuberculosis and malaria combined. In 1991, The World Bank, the world's largest lender, pledged that it would no longer support tobacco-related projects. It was expected that other financial investors would follow, but most did not respond to this call. As a result, several financial institutions continue to invest in tobacco and fuel an epidemic to an unprecedented scale. Using tobacco as a case in point, this review highlights the continuing investments among financial institutions which do not conform to 'socially responsible investments' and calls for monitoring and reporting such unethical practices. The paper also underscores the need to harmonise the numerous criteria, principles and voluntary codes that govern socially responsible investing and ensure that financial institutions comply with them.

    Objectives To compare the prevalence of periodontal disease between two randomly selected population-based studies (the Oral Infections and Vascular Disease Epidemiology Study (INVEST) and the Study of Health in Pomerania (SHIP)) and address relevant methodological issues. Methods Comparison was restricted to 55–81-years-olds. Attachment loss (AL), probing depth (PD), and tooth count were assessed in INVEST (full-mouth, six sites) and SHIP (half-mouth, four sites). Subjects were classified according to the CDC/AAP case definition. Recording protocols were standardized. Mixed linear or logistic models were used to compare INVEST with SHIP. Results Mean half-mouth AL was lower in INVEST vs. SHIP (INVEST: 2.9mm versus SHIP: 4.0mm, p<0.05). Findings were similar across multiple periodontal disease definitions. After equalisation of recording protocols and adjustment for periodontal risk factors, mean AL and PD were 1.2mm and 0.3mm lower in INVEST vs. SHIP (p<0.001). The odds for severe periodontitis (CDC/AAP) was 0.2-fold in INVEST vs. SHIP (p<0.001). Confounding effects of age, gender, race/ethnicity, education, and use of interdental care devices were highest as indicated by change-in-estimate for study. Conclusion Implementation of the proposed method for comparison of epidemiological studies revealed that periodontitis was less prevalent in INVEST compared to SHIP, even after extensive risk-factor adjustment.

    In an effort to increase the livability of its cities, public agencies in Australia are investing in green infrastructure to improve public health, reduce heat island effects and transition toward water sensitive urban design. In this paper, we present a simple and replicable approach to building a business case for green infrastructure. This approach requires much less time and resources compared to other methods for estimating the social and economic returns to society from such investments. It is a pragmatic, reasonably comprehensive approach that includes socio-demographic profile of potential users and catchment analysis to assess the economic value of community benefits of the investment. The approach has been applied to a case study area in the City of Brimbank, a western suburb of Greater Melbourne. We find that subject to a set of assumptions, a reasonable business case can be made. We estimate potential public benefits of avoided health costs of about AU$75,049 per annum and potential private benefits of AU$3.9 million. The project area is one of the most poorly serviced areas in the municipality in terms of quality open spaces and the potential beneficiaries are from relatively low income households with less than average health status and education levels. The values of cultural (recreational benefits, avoided health costs, and increased property values) and regulating (reduction in heat island effect and carbon sequestration) ecosystem services were quantified that can potentially offset annual maintenance costs.

  7. What can we learn from the existing evidence of the business case for investments in nursing care: importance of content, context, and policy environment.

    Yakusheva, Olga; Wholey, Douglas; Frick, Kevin D

    2013-04-01

    Decisions of health care institutions to invest in nursing care are often guided by mixed and conflicting evidence of effects of the investments on organizational function and sustainability. This paper uses new evidence generated through Interdisciplinary Nursing Quality Research Initiative (INQRI)-funded research and published in peer-reviewed journals, to illustrate where the business case for nursing investments stands and to discuss factors that may limit the existing evidence and its transferability into clinical practice. We conclude that there are 3 limiting factors: (1) the existing business case for nursing investments is likely understated due to the inability of most studies to capture spillover and long-run dynamic effects, thus causing organizations to forfeit potentially viable nursing investments that may improve long-term financial stability; (2) studies rarely devote sufficient attention to describing the content and the organization-specific contextual factors, thus limiting generalizability; and (3) fragmentation of the current health care delivery and payment systems often leads to the financial benefits of investments in nursing care accruing outside of the organization incurring the costs, thus making potentially quality-improving and cost-saving interventions financially unattractive from the organization's perspective. The payment reform, with its emphasis on high-quality affordable patient-centered care, is likely to strengthen the business case for investments in nursing care. Methodologically rigorous approaches that focus on broader societal implications of investments in nursing care, combined with a thorough understanding of potential barriers and facilitators of nursing change, should be an integral part of future research and policy efforts.

    Transmission infrastructure is an integral component of safeguarding the stability of electricity delivery. However, existing studies of transmission infrastructure mostly rely on a simple review of the network, while the analysis of investments remains rudimentary. This study conducted the first regionally focused analysis of investments in transmission infrastructure in China to help optimize its structure and reduce investment costs. Using State Grid data, the investment costs, under various voltages, for transmission lines and transformer substations are calculated. By analyzing the regional profile of cumulative investment in transmission infrastructure, we assess correlations between investment, population, and economic development across the regions. The recent development of ultra-high-voltage transmission networks will provide policy-makers new options for policy development.

Part of that preparation will entail knowing, with greater precision, what the scale and scope of our specific global health challenges are and what resources are needed to address them. However, how can we know the magnitude of the challenge, and what resources are needed without knowing the current status of the world through accurate primary data? Once we know the current status, how can we decide on an intervention today with a predicted impact decades out if we cannot project into that future? Making a case for more investments will require not just better data generation and sharing but a whole new level of sophistication in our analytical capability--a fundamental shift in our thinking to set expectations to match the reality. In this current status of a distributed world, being transparent with our assumptions and specific with the case for investing in global health is a powerful approach to finding solutions to the problems that have plagued us for centuries.

  14. Do Resit Exams Promote Lower Investments of Study Time? Theory and Data from a Laboratory Study

    2016-01-01

    Although many educational institutions allow students to resit exams, a recently proposed mathematical model suggests that this could lead to a dramatic reduction in study-time investment, especially in rational students. In the current study, we present a modification of this model in which we included some well-justified assumptions about learning and performance on multiple-choice tests, and we tested its predictions in two experiments in which participants were asked to invest fictional study time for a fictional exam. Consistent with our model, the prospect of a resit exam was found to promote lower investments of study time for a first exam and this effect was stronger for participants scoring higher on the cognitive reflection test. We also found that the negative effect of resit exams on study-time investment was attenuated when access to the resit was made uncertain by making it probabilistic or dependent on obtaining a minimal, non-passing grade for the first attempt. Taken together, these results suggest that offering students resit exams may compromise the achievement of learning goals, and they raise the more general implication that second chances promote risky behavior.

  15. The case for investing in secondary education in sub-Saharan Africa (SSA): challenges and opportunities

    Fredriksen, Birger; Fossberg, Camilla Helgø

    2014-04-01

    Over the next two decades, sub-Saharan Africa will face substantial pressure to expand its secondary education system. This is driven by the current low development of secondary education compared to other world regions, continued rapid population growth, the increase in the enrolment and completion rates at the primary education level, and the upsurge in the demand for skills. This paper suggests that in order to help countries respond to these pressures, external partners should now increase their support for secondary education, in terms of academic as well as technical and vocational skills training. Given the attributes of the African economies and the continuing need for foundation skills, this paper argues that in the current situation, particularly the lower secondary level will have to be strengthened, in many cases through a longer basic education cycle for all. The necessary rapid expansion of secondary education will require substantial investments, and this paper discusses how aid allocation can be made more evidence-based and used in a more strategic way to make these investments more effective and sustainable. While aid will continue to have a role to play over the next decade especially in fragile states, in the long run it is African countries' capacity to achieve sustained economic growth which will be the single most important factor determining their ability to meet the financing needs.

    Amortization time and rationality has been discussed a lot in real estate investment research. As the price of real estate is driven by Geometric Brown Motion (GBM), whether the mortgagors should amortize in advance has become a key issue in amortization time research. This paper presents a new method to solve the problem by using the optimal stopping time theory and option pricing theory models. We discuss the option value in amortizing decision based on this model. A simulation method is used to test this method.

    2002-01-01

    Student, Master of Space Studies. International Space University. Strasbourg Central The objective of this paper is to analyze the possible commercial benefits that the global manufacturing space industry could obtain by investing in Latin-American countries. Spacecraft manufacturers have recently been complaining about small margins. They claim that customers demand technological advancement at the same time as they push for quick delivery and competitive prices. They also argue that operators (their main customers) do have great profits. Thus, manufacturers would like to raise the prices of their spacecraft (SpaceNews. January 7, 2002. P.17). This may sound logical, but it would be interesting to analyze if the industry could find alternative ways of saving money while remaining competitive. Mexico is a good example of a Latin-American country that has received foreign investment for establishing manufacturing and assembly plants for different industries. This has been mainly due to two special characteristics of the Mexican manufacturing workforce: low labor costs and qualified, reliable human resources. As a result, Mexican manufacturing industry has acquired a solid reputation worldwide. A similar story can be told about other industries such as electronics, computer assembly, clothes, etc. It is probably worth to make an analogy with a labor-demanding industry that already has experience in the Mexican market: the car industry has found a formula to keep manufacturing costs low while maintaining production and quality levels. Mexico currently manufactures and assembles cars for European, Japanese and American companies for the international market. If the same success story could be repeated for the spacecraft manufacturing industry, the benefits would be enormous. Manufacturers could consider relocating their plants to Mexico to manufacture and test parts or entire spacecraft. This would help reduce the cost of human labor, especially because of the long

    The case study approach allows in-depth, multi-faceted explorations of complex issues in their real-life settings. The value of the case study approach is well recognised in the fields of business, law and policy, but somewhat less so in health services research. Based on our experiences of conducting several health-related case studies, we reflect on the different types of case study design, the specific research questions this approach can help answer, the data sources that tend to be used, and the particular advantages and disadvantages of employing this methodological approach. The paper concludes with key pointers to aid those designing and appraising proposals for conducting case study research, and a checklist to help readers assess the quality of case study reports.

    Scope and method of study. The purpose of this study was to develop a comprehensive and interdisciplinary framework for determining the economic viability of investment in agricultural processing. The potential of the gasification-bioconversion process as a method for producing ethanol from lignocellulosic biomass was examined, using Oklahoma as a case study. To simultaneously account for the time value of investment funds and the discrete nature of the plant location and plant size decisions, a mixed integer mathematical programming formulation was augmented with an investment decision rule. Specifically, the model determined combinations of plant locations, plant sizes, feedstock combinations, biomass production options (fertility levels, etc), biomass harvest and transportation options (vertically integrated or atomistic), and biomass storage options that maximize industry net present worth. Incorporated also is the tradeoff among harvesting over extended periods, storing harvested biomass in the field and/or storing biomass at the plant. Findings and conclusions. If the price of ethanol is 1.25 per gallon and the other base assumptions hold, three 100 million gallon per year plants would be located in Oklahoma, with a net present worth of US 553,614,554. These earnings would drop by about 11 percent if the price of fossil fuel increases enough to render ethanol competitive without subsidies. In general, given the assumptions of the base model, an ethanol industry would be justified if the unsubsidized market price of ethanol is at least $0.78. The results also indicate that introduction of switchgrass as a potential feedstock would double the number of plants and more than double the profitability of the industry. Further research needs to focus on determining reliable estimates of the ethanol yield rate. Although the gasification-bioconversion process can theoretically produce in excess of 100 gallons of ethanol per ton of biomass, such yields are yet to be

    This white paper makes a case for Sandia National Laboratories investments in complex adaptive systems science and technology (S&T) -- investments that could enable higher-value-added and more-robustly-engineered solutions to challenges of importance to Sandia's national security mission and to the nation. Complex adaptive systems are ubiquitous in Sandia's national security mission areas. We often ignore the adaptive complexity of these systems by narrowing our 'aperture of concern' to systems or subsystems with a limited range of function exposed to a limited range of environments over limited periods of time. But by widening our aperture of concern we could increase our impact considerably. To do so, the science and technology of complex adaptive systems must mature considerably. Despite an explosion of interest outside of Sandia, however, that science and technology is still in its youth. What has been missing is contact with real (rather than model) systems and real domain-area detail. With its center-of-gravity as an engineering laboratory, Sandia's has made considerable progress applying existing science and technology to real complex adaptive systems. It has focused much less, however, on advancing the science and technology itself. But its close contact with real systems and real domain-area detail represents a powerful strength with which to help complex adaptive systems science and technology mature. Sandia is thus both a prime beneficiary of, as well as potentially a prime contributor to, complex adaptive systems science and technology. Building a productive program in complex adaptive systems science and technology at Sandia will not be trivial, but a credible path can be envisioned: in the short run, continue to apply existing science and technology to real domain-area complex adaptive systems; in the medium run, jump-start the creation of new science and technology capability through Sandia's Laboratory Directed Research and Development program; and

    Case studies and case reports form an important and ever growing part of scientific and scholarly literature. The paper deals with the share and citation rate of these publication types on different fields of research. In general, evidence seems to support the opinion that an excessive number of such publications may negatively influence the impact factor of the journal. In the literature of scientometrics, case studies (at least the presence of the term "case study" in the titles of the papers) have a moderate share, but their citation rate is practically equal to that of other publication types.

    Background Amid local government budget cuts, there is concern that the ring-fenced public health grant is being appropriated, and Directors of Public Health (DsPH) find it difficult to make the case for investment in public health activity. This paper describes what DsPH are making the case for, the components of their case and how they present the case for public health. Methods Thirteen semi-structured telephone interviews and a group discussion were carried out with DsPH (November 2013 to May 2014) in the Southern region of England. Results DsPH make the case for control of the public health grant and investing in action on wider determinants of health. The cases they present incorporate arguments about need, solutions and their effectiveness, health outcomes, cost and economic impact but also normative, political arguments. Many types of evidence were used to substantiate the cases; evidence was carefully framed to be accessible and persuasive. Conclusions DsPH are responding to a new environment; economic arguments and evidence of impact are key components of the case for public health, although multiple factors influence local government (LG) decisions around health improvement. Further evidence of economic impact would be helpful in making the case for public health in LG. PMID:25775932

  10. Debt, investment and endowment accumulation: the case of not-for-profit hospitals.

    2002-09-01

    Not-for-profit hospitals benefit from special tax rules that allow state authorities to issue tax-exempt bonds on their behalf, which may affect their investment and financing choices. Hospitals may respond by increasing their investment in physical assets; however, they may also engage in tax arbitrage by using the tax-exempt debt while maintaining endowment assets. The paper combines data from tax (information) returns and the annual survey of hospitals by the American Hospital Association for 1993-1996. Overall, the results are consistent with substantial tax planning by not-for-profit hospitals. Of the US$ 55.9 billion in tax-exempt liabilities of hospitals in 1996, as much as US$ 32.6 billion could have been eliminated if hospitals spent their endowments instead of borrowing. Furthermore, controlling for hospital size (in terms of revenues and operating assets), endowment assets are associated with a higher ratio of tax-exempt (or total) debt to operating assets. In contrast, endowment assets are not related to taxable debt suggesting that the effects of the endowment on borrowing are motivated by tax incentives. Investment and endowment accumulation regressions suggest that increases in debt increase both physical investment and endowment accumulation but these effects are concentrated among cash-rich hospitals for which the effects on endowment accumulation effects are larger than the effects on physical investment.

    Prospective cohorts have played a major role in understanding the contribution of diet, physical activity, medical conditions, and genes to the development of many diseases, but have not been widely used for occupational exposures. Studies in agriculture are an exception. We draw upon our experience using this design to study agricultural workers to identify conditions that might foster use of prospective cohorts to study other occupational settings. Prospective cohort studies are perceived by many as the strongest epidemiologic design. It allows updating of information on exposure and other factors, collection of biologic samples before disease diagnosis for biomarker studies, assessment of effect modification by genes, lifestyle, and other occupational exposures, and evaluation of a wide range of health outcomes. Increased use of prospective cohorts would be beneficial in identifying hazardous exposures in the workplace. Occupational epidemiologists should seek opportunities to initiate prospective cohorts to investigate high priority, occupational exposures. PMID:25603935

    This series of three case studies illustrates the validity and usefulness of MIDAS, a microcomputer-based tool for integrated resource planning under uncertainty. The first, at Union Electric, serves to test and validate the model and to illustrate its use for demand/supply option evaluation. Focusing on nuclear plant life extension, the Virginia Power case demonstrates the model's extensive detail, particularly in the production cost and financial areas, as well as its flexibility in addressing approximately 70 uncertainty scenarios. Puget Sound Power Light, the third case, used MIDAS for the preparation of its integrated resource plan. A 108-endpoint decision tree illustrates the full power of the decision analysis capability.

  3. Long-term effects of health investments and parental favoritism: the case of breastfeeding.

    PubMed

    Fletcher, Jason M

    2011-11-01

    This paper re-examines the effects of breastfeeding on long-term educational outcomes using longitudinal data on siblings. While family-fixed effects allow controls for all shared family factors, these estimators are sensitive to compensating or reinforcing behaviors by parents. These biases may be particularly important for estimating the effects of parental investment such as breast feeding, where sibling discordance may be difficult to treat as a random outcome and may result in persistence in differential investments between siblings. This paper uses a unique question asked to adolescent siblings about parental favoritism to adjust for potential reinforcing behavior by parents. Standard fixed effects estimates suggest important long-term educational effects of breastfeeding; however, these effects are uniformly eliminated after focusing on families who treat siblings equally. These findings shed light on the mechanisms linking associations between breastfeeding and longer term outcomes. PMID:20960419

  9. Valuation of clean energy investments: The case of the Zero Emission Coal (ZEC) technology

    NASA Astrophysics Data System (ADS)

    Yeboah, Frank Ernest

    Today, coal-fired power plants produce about 55% of the electrical energy output in the U.S. Demand for electricity is expected to grow in future. Coal can and will continue to play a substantial role in the future global energy supply, despite its high emission of greenhouse gases (e.g. CO2 etc.) and low thermal energy conversion efficiency of about 37%. This is due to the fact that, it is inexpensive and global reserves are abundant. Furthermore, cost competitive and environmentally acceptable energy alternatives are lacking. New technologies could also make coal-fired plants more efficient and environmentally benign. One such technology is the Zero Emission Carbon (ZEC) power plant, which is currently being proposed by the ZECA Corporation. How much will such a technology cost? How competitive will it be in the electric energy market when used as a technology for mitigating CO2 emission? If there were regulatory mechanisms, such as carbon tax to regulate CO2 emission, what would be the minimum carbon tax that should be imposed? How will changes in energy policy affect the implementation of the ZEC technology? How will the cost of the ZEC technology be affected, if a switch from coal (high emission-intensive fuel) to natural gas (low emission-intensive fuel) were to be made? This work introduces a model that can be used to analyze and assess the economic value of a ZEC investment using valuation techniques employed in the electric energy industry such as revenue requirement (e.g. cost-of-service). The study concludes that the cost of service for ZEC technology will be about 95/MWh at the current baseline scenario of using fuel cell as the power generation system and coal as the primary fuel, and hence will not be competitive in the energy markets. For the technology to be competitive, fuel cell capital cost should be as low as 500/kW with a lifetime of 20 years or more, the cost of capital should be around 10%, and a carbon tax of 30/t of CO2 should be in place

  11. Climate change, water security and the need for integrated policy development: the case of on-farm infrastructure investment in the Australian irrigation sector

    2012-09-01

    The Australian Government is currently addressing the challenge of increasing water scarcity through significant on-farm infrastructure investment to facilitate the adoption of new water-efficient pressurized irrigation systems. However, it is highly likely that conversion to these systems will increase on-farm energy consumption and greenhouse gas (GHG) emissions, suggesting potential conflicts in terms of mitigation and adaptation policies. This study explored the trade-offs associated with the adoption of more water efficient but energy-intensive irrigation technologies by developing an integrated assessment framework. Integrated analysis of five case studies revealed trade-offs between water security and environmental security when conversion to pressurized irrigation systems was evaluated in terms of fuel and energy-related emissions, except in cases where older hand-shift sprinkler irrigation systems were replaced. These results suggest that priority should be given, in implementing on-farm infrastructure investment policy, to replacing inefficient and energy-intensive sprinkler irrigation systems such as hand-shift and roll-line. The results indicated that associated changes in the use of agricultural machinery and agrochemicals may also be important. The findings of this study support the use of an integrated approach to avoid possible conflicts in designing national climate change mitigation and adaptation policies, both of which are being developed in Australia.

  12. The economics of comparative effectiveness studies: societal and private perspectives and their implications for prioritizing public investments in comparative effectiveness research.

    2010-01-01

    Comparative effectiveness research (CER) can provide valuable information for patients, providers and payers. These stakeholders differ in their incentives to invest in CER. To maximize benefits from public investments in CER, it is important to understand the value of CER from the perspectives of these stakeholders and how that affects their incentives to invest in CER. This article provides a conceptual framework for valuing CER, and illustrates the potential benefits of such studies from a number of perspectives using several case studies. We examine cases in which CER provides value by identifying when one treatment is consistently better than others, when different treatments are preferred for different subgroups, and when differences are small enough that decisions can be made based on price. We illustrate these findings using value-of-information techniques to assess the value of research, and by examining changes in pharmaceutical prices following publication of a comparative effectiveness study. Our results suggest that CER may have high societal value but limited private return to providers or payers. This suggests the importance of public efforts to promote the production of CER. We also conclude that value-of-information tools may help inform policy decisions about how much public funds to invest in CER and how to prioritize the use of available public funds for CER, in particular targeting public CER spending to areas where private incentives are low relative to social benefits.

  13. Geography and the costs of urban energy infrastructure: The case of electricity and natural gas capital investments

    NASA Astrophysics Data System (ADS)

    Senyel, Muzeyyen Anil

    Investments in the urban energy infrastructure for distributing electricity and natural gas are analyzed using (1) property data measuring distribution plant value at the local/tax district level, and (2) system outputs such as sectoral numbers of customers and energy sales, input prices, company-specific characteristics such as average wages and load factor. Socio-economic and site-specific urban and geographic variables, however, often been neglected in past studies. The purpose of this research is to incorporate these site-specific characteristics of electricity and natural gas distribution into investment cost model estimations. These local characteristics include (1) socio-economic variables, such as income and wealth; (2) urban-related variables, such as density, land-use, street pattern, housing pattern; (3) geographic and environmental variables, such as soil, topography, and weather, and (4) company-specific characteristics such as average wages, and load factor. The classical output variables include residential and commercial-industrial customers and sales. In contrast to most previous research, only capital investments at the local level are considered. In addition to aggregate cost modeling, the analysis focuses on the investment costs for the system components: overhead conductors, underground conductors, conduits, poles, transformers, services, street lighting, and station equipment for electricity distribution; and mains, services, regular and industrial measurement and regulation stations for natural gas distribution. The Box-Cox, log-log and additive models are compared to determine the best fitting cost functions. The Box-Cox form turns out to be superior to the other forms at the aggregate level and for network components. However, a linear additive form provides a better fit for end-user related components. The results show that, in addition to output variables and company-specific variables, various site-specific variables are statistically

  14. The increasing burden of injuries in Eastern Europe and Eurasia: making the case for safety investments.

    PubMed

    Hyder, Adnan A; Aggarwal, Anju

    2009-01-01

    Injuries are one of the leading causes of death and disability in Europe. Within Europe, death rates due to injuries are 60% higher in Eastern compared to Western Europe. This is especially due to unintentional injuries such as road traffic injuries, which is the 2nd leading cause of death in those 5-29 years. The cost of injuries is estimated at 1-2% of GNP. Compared to the burden, the number and types of programs are limited in the Eastern European region. However, the literature reveals the existence of cost-effective interventions for regional and national policy consideration. This is a need to appreciate this problem and promote investments to prevent the high economic and societal costs due to injuries. Results from selected injury prevention programs have shown considerable success and these, if effectively adopted in this region, will make a significant difference in reducing the heavy toll of injuries on lives of people. This paper calls on aid donor agencies and governments to plan and implement injury prevention programs as part of their portfolio of investments, in the Eastern European region.

  15. Are Investments in Disease Prevention Complements? The Case of Statins and Health Behaviors

    PubMed Central

    Kaestner, Robert; Darden, Michael; Lakdawalla, Darius

    2014-01-01

    We obtain estimates of associations between statin use and health behaviors. Statin use is associated with a small increase in BMI and moderate (20% to 33%) increases in the probability of being obese. Statin use was also associated with a significant (e.g., 15% of mean) increase in moderate alcohol use among men. There was no consistent evidence of a decrease in smoking associated with statin use, and exercise worsened somewhat for females. Statin use was associated with increased physical activity among males. Finally, there was evidence that statin use increased the use of blood pressure medication and aspirin for both males and females, although estimates varied considerably in magnitude. These results are consistent with the hypothesis that healthy diet is a strong substitute for statins, but there is only uneven evidence for the hypothesis that investments in disease prevention are complementary.

  16. The case for renewed investment in the district nursing specialist practitioner qualification.

    PubMed

    Longstaff, Fiona

    2013-09-01

    District nursing as a profession has been under significant threat over the last few years due to a lack of foresight and funding, resulting in an undervalued and underinvested workforce. The once-heralded specialist practitioner programme was slowly decommissioned in all but a handful of universities, leaving no alternative but for community trusts to employ staff nurses in team leader roles without the development the added qualification gave them. In light of the renewed focus on the fundamental advancement of district nurses and recent Government publications clearly reinforcing the district nurse's role, this article argues for the need for educational commissioners and workforce planners to commit to continued investment in this vital profession.

    Within the Veterans Health Administration (VHA), the largest integrated health care system in the US, approximately 8.5 million Veteran patients receive informal care. Despite a need for training, half of VHA caregivers report that they have not received training that they deemed necessary. Rigorous study is needed to identify effective ways of providing caregivers with the skills they need. This paper describes the Helping Invested Families Improve Veterans' Experience Study (HI-FIVES), an ongoing randomized controlled trial that is evaluating a skills training program designed to support caregivers of cognitively and/or functionally impaired, community-dwelling Veterans who have been referred to receive additional formal home care services. This two-arm randomized controlled trial will enroll a total of 240 caregiver-patient dyads. For caregivers in the HI-FIVES group, weekly individual phone training occurs for 3 weeks, followed by 4 weekly group training sessions, and two additional individual phone training calls. Caregivers in usual care receive information about the VA Caregiver Support Services Program services, including a hotline number. The primary outcome is the number of days a Veteran patient spends at home in the 12 months following randomization (e.g. not in the emergency department, inpatient or nursing home setting). Secondary outcomes include patient VHA health care costs, patient and caregiver satisfaction with VHA health care, and caregiver depressive symptoms. Outcomes from HI-FIVES have the potential to improve our knowledge of how to maximize the ability to maintain patients safely at home for caregivers while preventing poor mental health outcomes among caregivers.

    In this article I posit and examine certain criteria and qualities for ending an analysis. The case study describes the end phase of a four-year psychoanalysis in which the patient's decision to move to another area forced the end of his analysis. We continued to explore and work through his core neurotic conflicts that included issues of competitive rivalry, dominance and submission, control, and anxiety about birth and death. A shift in the transference from me as a negative father to me as a supportive but competitive older brother was also examined in the context of ending treatment as well as other aspects of the transference. In addition, we analyzed the meaning of his ending treatment based on an extra-analytic circumstance. In discussing this phase of treatment, the definition and history of the term "termination" and its connotations are reviewed. Various criteria for completing an analysis are examined, and technical observations about this phase of treatment are investigated. It was found that while a significant shift in the transference occurred in this phase of the patient's analysis, conflicts related to the transference were not "resolved" in the classical sense. Terminating treatment was considered as a practical matter in which the patient's autonomy and sense of choice were respected and analyzed. PMID:26583444

    Investors are a heterogeneous group, they may be large or small, rich or poor, expert or lay man and not all investors need equal degree of protection (Mayya, 1996). An investor has three objectives while investing his money, namely safety of invested money, liquidity position of invested money and return on investment. The return on investment may further be divided into capital gain and the rate of return on investment as interest or dividend. Among all investment options available, securities are considered the most challenging as well as rewarding. Securities include shares, debentures, derivatives, units of mutual funds, Government securities etc. An investor may be an individual or corporate legal entity investing funds with a view to derive maximum economic advantage from investment such as rate of return, capital appreciation, marketability, tax advantage and convenience of investment.The Capital market facilitates mobilization of savings of individuals and pools them into reservoir of capital which can be used for the economic development of a country. An efficient capital market is essential for raising capital by the corporate sector of the economy and for the protection of the interest of investors in corporate securities. There arises a need to strike a balance between raising of capital for economic development on one side and protection of investors on the other. Unless the interests of investors are protected, raising of capital, by corporates is not possible. Like, the primary objective of a senior citizenís asset allocation is the generation of regular income.

  11. Ecosystem services in urban water investment.

    Kandulu, John M; Connor, Jeffery D; MacDonald, Darla Hatton

    2014-12-01

    Increasingly, water agencies and utilities have an obligation to consider the broad environmental impacts associated with investments. To aid in understanding water cycle interdependencies when making urban water supply investment decisions, an ecosystem services typology was augmented with the concept of integrated water resources management. This framework is applied to stormwater harvesting in a case study catchment in Adelaide, South Australia. Results show that this methodological framework can effectively facilitate systematic consideration and quantitative assessment of broad environmental impacts of water supply investments. Five ecosystem service impacts were quantified including provision of 1) urban recreational amenity, 2) regulation of coastal water quality, 3) salinity, 4) greenhouse gas emissions, and 5) support of estuarine habitats. This study shows that ignoring broad environmental impacts can underestimate ecosystem service benefits of water supply investments by a value of up to A$1.36/kL, or three times the cost of operating and maintenance of stormwater harvesting. Rigorous assessment of the public welfare impacts of water infrastructure investments is required to guide long-term optimal water supply investment decisions. Numerous challenges remain in the quantification of broad environmental impacts of a water supply investment including a lack of peer-reviewed studies of environmental impacts, aggregation of incommensurable impacts, potential for double-counting errors, uncertainties in available impact estimates, and how to determine the most suitable quantification technique.

  15. Investment Evaluation of RFID TechnologyApplications: An Evolution Perspective

    NASA Astrophysics Data System (ADS)

    Dimakopoulou, Andriana; Pramatari, Katerina; Karagiannaki, Angeliki; Papadopoulos, George; Paraskevopoulos, Antonis

    Prior empirical research on the evaluation of RFID technologytreats and assesses individual RFID applications independently and in isolation from each other. However, literature on investment evaluation of information technologies has recognised and utilised the significance of evaluating "interdependent" information systems (IS) projects with synergies. Moreover, previous studies when appraising the business value of an RFID investment ignore its opportunity to offer and evolve into additional follow-on investments in the future. Nevertheless, the importance of this notion has been acknowledged by the pertinent literature for the evaluation of other information technologies. This chapter proposes an approach for the investment evaluation of RFID applications considering them rather as a bundle of interdependent and sequential investments than as stand-alone ones. The results from a case study demonstrate how the proposed approach can be employed for the evaluation of RFID projects and offering an additional insight into evaluating investments in RFID applications.

    Everyone in science should have ethics education training. I have seen graduate students taken advantage of by their mentors. Many of us have seen misconduct...but what should we do about it? Young scientists are often unaware of the rules in science and make mistakes because of their ignorance of the rules in that particular field of study. Then there are an increasing number of cases in the news of overt cases of misrepresentation in science. All are welcome to attend this discussion of case studies. A case study on topics such as: how to treat data properly, how our values in science affect our work, who gets authorship on scientific papers, who is first author on a paper, what you should do if you uncover misconduct or plagiarism in your university, and we will discuss the scientist's role in society. This will be a painless, non-confrontational small group, then large group discussion of each case

    Breaking the students into small, collaborative learning groups to solve a meaningful task together is one of the most successful and fully evaluated teaching techniques implemented over the last century. Although there are many ways to accomplish small group learning, a long-standing and consistently successful collaborative class activity is to use the case study teaching strategy. The use of case studies is common in medical schools and law schools, but not so common in the teaching of astronomy. Case studies create meaningful conversations among students and with the professor by focusing on life-like dilemmas to be solved. Case study tasks ask audience members to synthesize several ideas or evaluate scenarios that have not been explicitly presented to them in the lecture or in available readings.

  5. The Association of Investment Model Variables and Dyadic Patterns of Physical Partner Violence: A Study of College Women.

    Dixon, Kristiana J; Edwards, Katie M; Gidycz, Christine A

    2016-10-01

    Previous research has examined the association between intimate partner violence (IPV) victimization experiences and investment model variables, particularly with relation to leaving intentions. However, research only has begun to explore the impact that various dyadic patterns of IPV (i.e., unidirectional victimization, unidirectional perpetration, bidirectional violence, and non-violence) have on investment model variables. Grounded in behavioral principles, the current study used a sample of college women to assess the impact that perpetration and victimization have on investment model variables. Results indicated that 69.2% of the sample was in a relationship with no IPV. Among those who reported IPV in their relationships, 11.9% reported unidirectional perpetration, 10.6% bidirectional violence, and 7.4% unidirectional victimization. Overall, the findings suggest that women's victimization (i.e., victim only and bidirectional IPV) is associated with lower levels of satisfaction and commitment, and that women's perpetration (i.e., perpetration only and bidirectional IPV) is associated with higher levels of investment. Women in bidirectionally violent relationships reported higher quality alternatives than women in non-violent relationships. The current study emphasizes the importance of considering both IPV perpetration and IPV victimization experiences when exploring women's decisions to remain in relationships.

    As with any technological innovation, time refines the technology, improving upon the original version of the innovative product. The initial GM crops had single traits for either herbicide tolerance or insect resistance. Current varieties have both of these traits stacked together and in many cases other abiotic and biotic traits have also been stacked. This innovation requires investment. While this is relatively straight forward, certain conditions need to exist such that investments can be facilitated. The principle requirement for investment is that regulatory frameworks render consistent and timely decisions. If the certainty of regulatory outcomes weakens, the potential for changes in investment patterns increases.   This article provides a summary background to the leading plant breeding technologies that are either currently being used to develop new crop varieties or are in the pipeline to be applied to plant breeding within the next few years. Challenges for existing regulatory systems are highlighted. Utilizing an option value approach from investment literature, an assessment of uncertainty regarding the regulatory approval for these varying techniques is undertaken. This research highlights which technology development options have the greatest degree of uncertainty and hence, which ones might be expected to see an investment decline. PMID:24499745

    2013-04-18

    Leishmaniasis in many ways offers a unique vaccine case study. Two reasons for this are that leishmaniasis is a disease complex caused by several different species of parasite that are highly related, thus raising the possibility of developing a single vaccine to protect against multiple diseases. Another reason is the demonstration that a leishmaniasis vaccine may be used therapeutically as well as prophylactically. Although there is no registered human leishmaniasis vaccine today, immunization approaches using live or killed organisms, as well as defined vaccine candidates, have demonstrated at least some degree of efficacy in humans to prevent and to treat some forms of leishmaniasis, and there is a vigorous pipeline of candidates in development. Current approaches include using individual or combined antigens of the parasite or of salivary gland extract of the parasites' insect vector, administered with or without formulation in adjuvant. Animal data obtained with several vaccine candidates are promising and some have been or will be entered into clinical testing in the near future. There is sufficient scientific and epidemiological justification to continue to invest in the development of vaccines against leishmaniasis.

    The ability to design gating systems that reliably feed and support investment castings is often the result of cut-and-try'' methodology. Factors such as hot tearing, porosity, cold shuts, misruns, and shrink are defects often corrected by several empirical gating design iterations. Sandia National Laboratories is developing rules that aid in removing the uncertainty involved in the design of gating systems for investment castings. In this work, gating geometries used for filling of thin walled investment cast 17-4PH stainless steel flat plates were investigated. A full factorial experiment evaluating the influence of metal pour temperature, mold preheat temperature, and mold channel thickness were conducted for orientations that filled a horizontal flat plate from the edge. A single wedge gate geometry was used for the edge-gated configuration. Thermocouples placed along the top of the mold recorded metal front temperatures, and a real-time x-ray imaging system tracked the fluid flow behavior during filling of the casting. Data from these experiments were used to determine the terminal fill volumes and terminal fill times for each gate design.

  5. Quantification of the effects of quality investment on the Cost of Poor Quality: A quasi-experimental study

    NASA Astrophysics Data System (ADS)

    Tamimi, Abdallah Ibrahim

    Quality management is a fundamental challenge facing businesses. This research attempted to quantify the effect of quality investment on the Cost of Poor Quality (COPQ) in an aerospace company utilizing 3 years of quality data at United Launch Alliance, a Boeing -- Lockheed Martin Joint Venture Company. Statistical analysis tools, like multiple regressions, were used to quantify the relationship between quality investments and COPQ. Strong correlations were evident by the high correlation coefficient R2 and very small p-values in multiple regression analysis. The models in the study helped produce an Excel macro that based on preset constraints, optimized the level of quality spending to minimize COPQ. The study confirmed that as quality investments were increased, the COPQ decreased steadily until a point of diminishing return was reached. The findings may be used to develop an approach to reduce the COPQ and enhance product performance. Achieving superior quality in rocket launching enhances the accuracy, reliability, and mission success of delivering satellites to their precise orbits in pursuit of knowledge, peace, and freedom while assuring safety for the end user.

    Population investment is a major topic in the studies of population and economic relations. In this particular area, numerous theoretical and practical problems are still in need of solution. Concerning the problem of population concept, there are three different approaches: (1) to determine the definition of population investment from the relationship between the population growth and the capital from national income used for investment, including investment in the newly increased population and investment in the entire population; (2) to explain population investment from the economic viewpoint that people are producers; and (3) to explain population investment from the expense needed to change a simple labor force to a skillful labor force. The expenses include educational costs, maintanance spending, wages needed to compensate workers in labor, costs for workers to master and learn modern scientific techniques to be used for production, and the costs of keeping a young labor force in the next generation.

    Identification of confounding factors, evaluation of their influence on cause-effect associations, and the introduction of appropriate ways to account for these factors are important considerations in designing case-control studies. This paper presents designs useful for these purposes, after first providing a statistical definition of a confounding factor. Differences in the ability to identify and evaluate confounding factors and estimate disease risk between designs employing stratification (matching) and designs randomly sampling cases and controls are noted. Linear logistic models for the analysis of data from such designs are described and are shown to liberalize design requirements and to increase relative risk estimation efficiency. The methods are applied to data from a multiple factor investigation of lung cancer patients and controls. PMID:540588

    This paper deals with the creation of appropriate conditions aimed at developing social services for reuse and recycling of waste electrical and electronic equipment (WEEE), by the inclusion of handicapped and Roma people in the workforce. Application areas for the project are the Hellenic (Greek) regions of Thessaly and North Aegean, where these groups suffer from professional and social exclusion. The efforts to reduce unemployment in the two aforementioned groups, together with the efforts to implement related Greek and European legislation for sustainable WEEE management, are examined here. Furthermore, networking and cooperation at local, regional and central levels between small enterprises, entrepreneurships and local authorities are examined, so that these social enterprises and their corresponding investments may support the development of the Greek alternative WEEE recycling system.

    This paper deals with the creation of appropriate conditions aimed at developing social services for reuse and recycling of waste electrical and electronic equipment (WEEE), by the inclusion of handicapped and Roma people in the workforce. Application areas for the project are the Hellenic (Greek) regions of Thessaly and North Aegean, where these groups suffer from professional and social exclusion. The efforts to reduce unemployment in the two aforementioned groups, together with the efforts to implement related Greek and European legislation for sustainable WEEE management, are examined here.

    The number of dementia patients is growing, and they require a variety of services, making integrated care essential for the ability to continue living in the community. Many healthcare systems in developed countries are exploring new approaches for delivering health and social care. The purpose of this study was to describe and analyse a new approach in extensive case management programmes concerned with long-term dementia care in The Netherlands. The focus is on the characteristics, and success and failure factors of these programmes.A multiple case study was conducted in eight regional dementia care provider networks in The Netherlands. Based on a literature study, a questionnaire was developed for the responsible managers and case managers of the eight case management programmes. During 16 semistructured face-to-face interviews with both respondent groups, a deeper insight into the dementia care programmes was provided. Project documentation for all the cases was studied. The eight programmes were developed independently to improve the quality and continuity of long-term dementia care. The programmes show overlap in terms of their vision, tasks of case managers, case management process and the participating partners in the local dementia care networks. Differences concern the targeted dementia patient groups as well as the background of the case managers and their position in the local dementia care provider network. Factors for success concern the expert knowledge of case managers, investment in a strong provider network and coherent conditions for effective inter-organizational cooperation to deliver integrated care. When explored, caregiver and patient satisfaction was high. Further research into the effects on client outcomes, service use and costs is recommended in order to further analyse the impact of this approach in long-term care. To facilitate implementation, with a focus on joint responsibilities of the involved care providers, policy

    Acute limb ischemia is a complication of severe peripheral arterial disease that can be a threatening limb as well as life. Multiple procedures exist today to help revascularize extremities; however, even with the latest technologies, surgical amputation of the limb may still be necessary. Cryoamputation, or physiologic amputation, is a method used to treat patients who are hemodynamically unstable for the operating room and who are in need of urgent amputation owing to arterial ischemia. This procedure is used in the rare instance where not only a persons' limb is threatened, but also their life. This is a case study regarding one patient who presented to the hospital with limb-threatening ischemia who became hemodynamically unstable owing to the rhabdomyolysis associated with the ischemia of his lower extremity. Cryoamputation was used to stabilize the patient and prevent further deterioration, so that he could safely undergo surgical amputation of the limb without an increase in mortality risk. Cryoamputation must be followed by formal surgical amputation when the patient is hemodynamically stabilized. It is not a limb salvaging, procedure but it is a life-saving procedure. This case study demonstrates the usefulness of the procedure and discusses the technique used for cryoamputation.

  19. A real options approach to biotechnology investment policy-the case of developing a Campylobacter vaccine to poultry.

    PubMed

    Lund, Mogens; Jensen, Jørgen Dejgård

    2016-06-01

    The aim of the article is to identify and analyse public-private incentives for the development and marketing of new animal vaccines within a real options methodological framework, and to investigate how real options methodology can be utilized to support economic incentives for vaccine development in a cost-effective way. The development of a vaccine against Campylobacter jejuni in poultry is applied as a case study. Employing the real options methodology, the net present value of the vaccine R&D project becomes larger than a purely probabilistic expected present value throughout the different stages of the project - and the net present value becomes larger, when more types of real options are taken into consideration. The insight from the real options analysis reveals opportunities for new policies to promote the development of animal vaccines. One such approach might be to develop schemes combining stage-by-stage optimized subsidies in the individual development stages, with proper account taken of investors'/developers' economic incentives to proceed, sell or cancel the project in the respective stages. Another way of using the real options approach to support the development of desirable animal vaccines could be to issue put options for the vaccine candidate, enabling vaccine developers to hedge against the economic risk from market volatility.

  1. The Economics of an Investment in Kaizen

    NASA Astrophysics Data System (ADS)

    Visuwan, Danupun

    2010-10-01

    Kaizen has been widely accepted as a continuous process improvement with the gradualist approach. This paper presents the research carried out to explore the pattern of an investment in Kaizen to enhance overall profit. System dynamics-based simulation has been employed with an optimization technique, a Steepest Ascent approach, to improve experimental variables e.g. the amount of spending on prevention and appraisal activities, the time and the amount to reduce the investment which results in maximum Net Present Value (NPV) of profit. The simulation model in this study is based on a Thai automobile manufacturer as a case study company. The result suggests that the investment in Kaizen should spend on activities to eliminate and detect all defects in the early phase and then reduce economically when the process is under controlled. It can be named as the `Hybrid quality improvement', which was proved in this study that it provides greater overall profit than the Stepwise Kaizen and the constant spending. This study also presents the behavior of quality costs and profit against time scale along the different patterns of the investment in Kaizen.

  3. Relations between people, relations about things: gendered investment and the case of the Lake Victoria fishery, Tanzania.

    PubMed

    Medard, Modesta

    2012-01-01

    Using the example of one of the African fisheries that has been most significantly transformed from family based to commercialized—that on Lake Victoria in Tanzania—this article considers the social nexus of decision making and focuses on analyzing women’s place. It is true that women have never been more than a minority in fisheries due to traditional inheritance patterns and new market structures, both of which bypass women in questions of ownership and decision making. We look in vain for fishwives, if this means female fish producers acting with a highly visible degree of economic and social autonomy. There is no vernacular term to identify women who work with fish or those rare women who own fishing vessels. And yet the absence of derogatory representation suggests that there have been few attempts to detract from women who are active in the fishery. Should we thus be aiming at more subtlety in our analytical approaches to fishing relations on Lake Victoria? The article unveils the ways in which women’s relations with fishermen are negotiated and how agreements are reached on behalf of their families. It explores for women’s empowerment via the customary social relations and management arrangements that exist in these riparian communities. The lake fishery has a basis for development, but its potential for the kind of growth that will have returns for future generations rests on an appreciation of how fisher-wives conceive of, and respond to, the opportunities, constraints and risks of investing in this fishery.

    We report the case of patient MN, diagnosed with frontotemporal dementia, who exhibited a severe impairment in writing letters and words in upper-case print in the face of accurate production of the same stimuli in lower-case cursive. In contrast to her written production difficulties, MN was unimpaired in recognizing visually presented letters and words in upper-case print. We find a modest benefit of visual form cueing in the written production of upper-case letters, despite an inability to describe or report visual features of letters in any case or font. This case increases our understanding of the allographic level of letter-shape representation in written language production. It provides strong support for previous reports indicating the neural independence of different types of case and font-specific letter-shape information; it provides evidence that letter-shape production does not require explicit access to information about the visual attributes of letter shapes and, finally, it reveals the possibility of interaction between processes involved in letter-shape production and perception.

    Concentrated Photovoltaics (CPV), once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed. As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

    These case studies provide small, selected samples of the results of assessments of articulation skills and their phonologic applications and give some information related to velopharyngeal function during speech. These illustrations were based chiefly on perceptual assessment of speech because this type of assessment is used routinely by SLPs, and does not require instrumentation. Indicators for referral and communication to a cleft palate team were derived from the perceptual evaluation. Other articles in this issue discuss procedures for evaluation in considerable detail. Early identification of possible velopharyngeal problems and early referral to a cleft palate team can help to resolve speech, language, and hearing disorders related to cleft palate and velopharyngeal dysfunction. People who comprise cleft palate and craniofacial teams are most likely to have the experience, and the special instrumentation necessary, to make a definitive diagnosis. The team's comprehensive multidisciplinary evaluation should lead to thorough consideration of the many factors that are important for treatment planning. The information and services provided by the team will assist the audiologist and SLP in the conduct of their services for these clients. In this way, the communication disorders specialist becomes an affiliate of the team. The affiliate not only acts as a referent, but also may provide the necessary longitudinal services. The best interests of the client are promoted by ongoing communication between the team and the affiliates of the team.

  12. Some problems about population investment.

    PubMed

    Liu, Z

    1983-01-01

    In this article, the concept--population investment--relates to population and economy for investment expenditures and economic gains. 3 economic approaches express this concept. 1) Population investment, which maintains the standard of living, may be considered separate from economic investment, which raises the per capita income. The original population and the increased population comprise total population. Increased population, composed of newborns, is nonproductive, lowering per capita output. Rapid population growth increases population investment and decreases economic investment so that the national economy does not improve. 2) Population investment regards people as producers in a narrow as well as broad sense. Each potential worker incurs labor reproduction expenses since he must be reared and educated before he becomes a producing laborer. Family and society labor reproduction expenditures depend upon costs for 1) prenatal care and delivery, 2) living expenses, 3) medical fees, 4) educational fees, and 5) related state expenditures, such as maternity wages and infant mortality costs. A 1979 study, using 191 cities, estimated costs of 6907 yuan in cities, 4830 yuan in towns, and 1630 yuan in rural areas to raise a child from conception through age 16. Researchers conclude that 1) raising the new labor force is more expensive in towns and cities than in rural areas, 2) families supply over 70% and the state less than 30%, of costs, and 3) living expenses make up over 60% of costs, with education taking 11.3% (rural) to 26.8% (urban). 3) Education fees (intelligence investment) form the third population investment function. Changes in labor quality as they effect national income illustrate the effects of intelligence investment. The authors theorize that intelligence investment is a fourth factor, with 1) increased work force size, 2) increased gross output, and 3) reduced material consumption in increasing the national income.

  15. Marginal accuracy of nickel chromium copings fabricated by conventional and accelerated casting procedures, produced with ringless and metal ring investment procedures: A comparative in vitro study

    PubMed Central

    Alex, Deepa; Shetty, Y. Bharath; Miranda, Glynis Anita; Prabhu, M. Bharath; Karkera, Reshma

    2015-01-01

    Background: Conventional investing and casting techniques are time-consuming and usually requires 2–4 h for completion. Accelerated nonstandard, casting techniques have been reported to achieve similar quality results in significantly less time, namely, in 30–40 min. During casting, it is essential to achieve compensation for the shrinkage of solidifying alloy by investment expansion. The metal casting ring restricts the thermal expansion of investment because the thermal expansion of the ring is lesser than that of the investment. The use of casting ring was challenged with the introduction of the ringless technique. Materials and Methods: A total of 40 test samples of nickel chromium (Ni-Cr) cast copings were obtained from the patterns fabricated using inlay casting wax. The 20 wax patterns were invested using metal ring and 20 wax patterns were invested using the ringless investment system. Of both the groups, 10 samples underwent conventional casting, and the other 10 underwent accelerated casting. The patterns were casted using the induction casting technique. All the test samples of cast copings were evaluated for vertical marginal gaps at four points on the die employing a stereo optical microscope. Results: The vertical marginal discrepancy data obtained were tabulated. Mean and standard deviations were obtained. Vertical discrepancies were analyzed using analysis of variance and Tukey honestly significantly different. The data obtained were found to be very highly significant (P < 0.001). Mean vertical gap was the maximum for Group II (53.64 μm) followed by Group IV (47.62 μm), Group I (44.83 μm) and Group III (35.35 μm). Conclusion: The Ni-Cr cast copings fabricated with the conventional casting using ringless investment system showed significantly better marginal fit than that of cast copings fabricated from conventional and accelerated casting with metal ring investment and accelerated casting using ringless investment since those copings had

    1996-03-01

    Congress has given NASA and the science community a reality check. The tight and ever shrinking budgets are trimming the fat from many space science programs. No longer can a Principal Investigator (PI) afford to waste development dollars on re-inventing spacecraft controllers, experiment/payload controllers, ground control systems, or test sets. Inheritance of the Ground Support Equipment (GSE) from one program to another is not a significant re-use of technology to develop a science mission in these times. Reduction of operational staff and highly autonomous experiments are needed to reduce the sustaining cost of a mission. The re-use of an infrastructure from one program to another is needed to truly attain the cost and time savings required. Interface and Control Systems, Inc. (ICS) has a long history of re-usable software. Navy, Air Force, and NASA programs have benefited from the re-use of a common control system from program to program. Several standardization efforts in the AIAA have adopted the Spacecraft Command Language (SCL) architecture as a point solution to satisfy requirements for re-use and autonomy. The Environmental Research Institute of Michigan (ERIM) has been a long-standing customer of ICS and are working on their 4th generation system using SCL. Much of the hardware and software infrastructure has been re-used from mission to mission with little cost for re-hosting a new experiment. The same software infrastructure has successfully been used on Clementine, and an end-to-end system is being deployed for the Far Ultraviolet Spectroscopic Explorer (FUSE) for Johns Hopkins University. A case study of the ERIM programs, Clementine and FUSE will be detailed in this paper.

    There is new interest in subjective experiences of schizophrenia. This kind of analysis emphasizes the subjective stories of patients, and the methods do not pretend to have the objectivity of science. However, the plausibility and the empathetic resonance of the single case may bring subjective confirmation to the validity of an insight and indicate new directions of research. Following this line, the authors present a study of 3 single cases of 'reflexive' residual type of schizophrenia. The methods for selecting the cases and the philosophical groundings of the concept of 'reflexive schizophrenia' are explained. The analysis of the single cases revealed that (1) schizophrenic persons' cognitive deficit is related to the constitution of common sense; (2) some schizophrenics cope with the cognitive deficit by creating a theoretical corpus of axioms stemming from common sense, namely the 'axioms of everyday life'; (3) this mechanism of coping is described as an inflexible attachment to 'axioms of everydayness', and (4) this attachment to common sense releases the patient from all personal investment of self in the process of anchoring in the living world and, on this basis, allows a relatively solid, although distant, attachment to reality. The nature of deficit in schizophrenia is also discussed by confronting the phenomenological point of view and the neuropsychological, that is the so-called 'theory of mind'.

    2015-01-01

    Aim To determine the cost effectiveness of increasing nurse staffing or changing the nursing skill mix in adult medical and/or surgical patients? Background Research has demonstrated that nurse staffing levels and skill mix are associated with patient outcomes in acute care settings. If increased nurse staffing levels or richer skill mix can be shown to be cost-effective hospitals may be more likely to consider these aspects when making staffing decisions. Design A systematic review of the literature on economic evaluations of nurse staffing and patient outcomes was conducted to see whether there is consensus that increasing nursing hours/skill mix is a cost-effective way of improving patient outcomes. We used the Cochrane Collaboration systematic review method incorporating economic evidence. Data sources The MEDLINE, CINAHL, SPORTDiscus and PsychINFO databases were searched in 2013 for published and unpublished studies in English with no date limits. Review methods The review focused on full economic evaluations where costs of increasing nursing hours or changing the skill mix were included and where consequences included nursing sensitive outcomes. Results Four-cost benefit and five-cost effectiveness analyses were identified. There were no cost-minimization or cost-utility studies identified in the review. A variety of methods to conceptualize and measure costs and consequences were used across the studies making it difficult to compare results. Conclusion This review was unable to determine conclusively whether or not changes in nurse staffing levels and/or skill mix is a cost-effective intervention for improving patient outcomes due to the small number of studies, the mixed results and the inability to compare results across studies.

  20. Ethical issues in case study publication: "making our case(s)" ethically.

    PubMed

    McCurdy, David B; Fitchett, George

    2011-01-01

    As chaplains develop richly detailed case studies for publication, ethical questions about case study construction and publication are emerging. Concerns about seeking patients' permission to publish material about them suggest additional questions and raise broad confidentiality and privacy issues. Confidentiality-related practices in health care and psychotherapy provide the most extensive guidance for chaplains, but healthcare chaplaincy has roots in religious and professional traditions with distinct notions of confidentiality that deserve consideration. Single case studies do not appear to be "research" requiring informed consent, yet their publication exposes patients to some risk of harm. Obtaining the patient's/"case study subject's" permission to publish, disguising non-essential information, and allowing the patient to review the case study can mitigate the risks. Striking a balance between protecting patients and providing sufficient detail to make case studies useful is a central ethical challenge of case study publication.

  1. Giant adrenal cyst: case study

    Carsote, M; Chirita, P; Terzea, D; Paun, S; Beuran, M

    2010-01-01

    One of the rarest situations regarding an adrenal incidentaloma is an adrenal cyst. We present the case of a 61Z–year old male patient diagnosed with peritonitis. During surgery, a right adrenal tumor of 2 cm is discovered. The patient was referred to endocrinology. 6 months later the diameter of the tumor is 7 times bigger than the initial stage. It has no secretory phenotype, except for the small increase of serum aldosterone and the 24–h 17–ketosteroids. Open right adrenalectomy is performed and a cyst of 15 cm is removed. The evolution after surgery is good. The pathological exam reveals an adrenal cyst with calcifications and osteoid metaplasia. The immunohistochemistry showed a positive reaction for CD34 and ACT in the vessels and VIM in the stroma. The adrenal cysts are not frequent and represent a challenge regarding the preoperative diagnostic and surgical procedure of resection. The pathological exam highlights the major aspects.

    The research presented in this dissertation covers three separate topics of conservation as defined by the National Science Foundation: 1) Materials Stabilization, Strengthening, Monitoring, and Repair; 2. Understanding Material Degradation and Aging; and 3) Materials and Structural Characterization of Cultural Heritage Objects (the 'technical study'). The first topic is addressed through a study to assess the consolidant tetraethoxysilane for the stabilization of alum treated wood. Falling under materials degradation studies is a study published in American Museum Novitates to understand how environmental conditions affect the aging of fossil resins from five different deposits. Two separate studies are included in technical study of cultural heritage objects which comprises the third research area of materials characterization. The first is a survey of red dyes used in Chinese paintings from the Ming Dynasty to the Early Republic (1364-1911). The second is a study of the pigments, dyes and binders used in Hawaiian barkcloth (kapa) from the 19th century.

    Background Studies consistently find that supportive neighbourhood built environments increase physical activity by encouraging walking and cycling. However, evidence on the cost-effectiveness of investing in built environment interventions as a means of promoting physical activity is lacking. In this study, we assess the cost-effectiveness of increasing sidewalk availability as one means of encouraging walking. Methods Using data from the RESIDE study in Perth, Australia, we modelled the cost impact and change in health-adjusted life years (HALYs) of installing additional sidewalks in established neighbourhoods. Estimates of the relationship between sidewalk availability and walking were taken from a previous study. Multistate life table models were used to estimate HALYs associated with changes in walking frequency and duration. Sensitivity analyses were used to explore the impact of variations in population density, discount rates, sidewalk costs and the inclusion of unrelated healthcare costs in added life years. Results Installing and maintaining an additional 10 km of sidewalk in an average neighbourhood with 19 000 adult residents was estimated to cost A$4.2 million over 30 years and gain 24 HALYs over the lifetime of an average neighbourhood adult resident population. The incremental cost-effectiveness ratio was A$176 000/HALY. However, sensitivity results indicated that increasing population densities improves cost-effectiveness. Conclusions In low-density cities such as in Australia, installing sidewalks in established neighbourhoods as a single intervention is unlikely to cost-effectively improve health. Sidewalks must be considered alongside other complementary elements of walkability, such as density, land use mix and street connectivity. Population density is particularly important because at higher densities, more residents are exposed and this improves the cost-effectiveness. Health gain is one of many benefits of enhancing neighbourhood

    The multifamily case studies that are the subject of this report were conducted to provide a better understanding of the approach taken by program operators in weatherizing large buildings. Because of significant variations in building construction and energy systems across the country, five states were selected based on their high level of multifamily weatherization. This report summarizes findings from case studies conducted by multifamily weatherization operations in five cities. The case studies were conducted between January and November 1994. Each of the case studies involved extensive interviews with the staff of weatherization subgrantees conducting multifamily weatherization, the inspection of 4 to 12 buildings weatherized between 1991 and 1993, and the analysis of savings and costs. The case studies focused on innovative techniques which appear to work well.

  18. Regional case studies--Africa.

    PubMed

    Prentice, Andrew M

    2009-01-01

    Africa is the final continent to be affected by the nutrition transition and, as elsewhere, is characterized by the paradoxical coexistence of malnutrition and obesity. Several features of the obesity epidemic in Africa mirror those in other emerging nations: it penetrates the richer nations and urban areas first with a strong urban- rural gradient; initially it affects the wealthy, but later there is a demographic switch as obesity becomes a condition more associated with poverty, and it shares many of the same drivers related to the increasing affordability of highly refined oils and carbohydrates, and a move away from subsistence farm work and towards sedentary lifestyles. Africa also has some characteristics of the obesity epidemic that stand out from other regions such as: (1) excepting some areas of the Pacific, Africa is probably the only region in which obesity (especially among women) is viewed culturally as a positive and desirable trait, leading to major gender differences in obesity rates in many countries; (2) most of Africa has very low rates of obesity in children, and to date African obesity is mostly an adult syndrome; (3) Africans seem genetically prone to higher rates of diabetes and hypertension in association with obesity than Caucasians, but seem to be relatively protected from dislipidemias; (4) the case-specific deaths and disabilities from diabetes and hypertension in Africa are very high due to the paucity of health services and the strain that the 'double burden' of disease places on health systems.

    2015-01-01

    The aim of this study is to provide an overview of the scientific activity of different psychoanalytic schools of thought in terms of the content and production of case studies published on ISI Web of Knowledge. Between March 2013 and November 2013, we contacted all case study authors included in the online archive of psychoanalytic and psychodynamic case studies (www.singlecasearchive.com) to inquire about their psychoanalytic orientation during their work with the patient. The response rate for this study was 45%. It appears that the two oldest psychoanalytic schools, Object-relations psychoanalysis and Ego psychology or “Classical psychoanalysis” dominate the literature of published case studies. However, most authors stated that they feel attached to two or more psychoanalytic schools of thought. This confirms that the theoretical pluralism in psychoanalysis stretches to the field of single case studies. The single case studies of each psychoanalytic school are described separately in terms of methodology, patient, therapist, or treatment features. We conclude that published case studies features are fairly similar across different psychoanalytic schools. The results of this study are not representative of all psychoanalytic schools, as some do not publish their work in ISI ranked journals. PMID:26483725

  20. Parental investment in child health in sub-Saharan Africa: a cross-national study of health-seeking behaviour

    PubMed Central

    2016-01-01

    Parents face trade-offs between investing in child health and other fitness enhancing activities. In humans, parental investment theory has mostly been examined through the analysis of differential child outcomes, with less emphasis on the actions parents take to further a particular offspring’s condition. Here, we make use of household data on health-seeking for children in a high mortality context where such behaviours are crucial for offspring survival. Using Demographic and Health Survey (DHS) data from 17 sub-Saharan African countries, we examine whether maternal factors (age, health, marital status) and child factors (birth order, health, sex, age) independently influence parental investment in health-seeking behaviours: two preventative behaviours (malaria net use and immunization) and two curative ones (treating fever and diarrhoea). Results indicate that children with lower birth order, older mothers and mothers with better health status have higher odds of investment. The effects of a child’s sex and health status and whether the mother is polygynously married vary depending on the type of health-seeking behaviour (preventative versus curative). We discuss how these results square with predictions from parental investment theory pertaining to the state of mothers and children, and reflect on some potential mechanisms and directions for future research.

    Using a resource dependency framework and financial theory, this study assessed the market, mission, operational, and financial factors associated with the level of cash and security investments in hospitals. We ranked hospitals in the study sample based on their cash and security investments as a percentage of total assets: hospitals in the high cash/security investment category were in the top 25th percentile of all hospitals; those in the low cash/security investment group were in the bottom 25th percentile. Findings indicate that high cash/security investment hospitals are under either public or private nonprofit ownership and have greater market share. They also serve more complex cases, offer more technology services, generate greater profits, incur a more stable patient revenue base, and maintain less debt. PMID:11252449

    Granuloma annulare (GA) is classified as localized, generalized/disseminated, subcutaneous, and perforating types. The studies show connection with diabetes mellitus, lipidic metabolic disorders, malignant diseases, thyroid disorders, infections (HBV, HCV, HIV). We performed a retrospective study between 2010-2011, regarding disseminated GA (GAD), and the relationship between GAD and other comorbidities. We clinically and histologically diagnosed eight cases of GAD. The patients were also investigated for the diagnosis of associated diseases. The treatment included topical corticosteroids, antihistamines, Calcipotriol/Betamethasone, Tacrolimus 0.03%, Pentoxifylline, Hydroxychloroquine. Therapeutic response was assessed one month and three months after hospitalization. Our patients were five women and three men, aged 46-68 years, mean age 57.25 years, with a disease history of one year and a half (between three months and four years). The lesions occurred in the upper extremities (eight cases), distal extremities (three cases), cervical area (two cases), and trunk (five cases). In seven cases, we found annular appearance and one patient had disseminated small papules eruption. Associated pathology was diabetes mellitus type II (five cases), overweight and obesity (five cases), dyslipidemia (three cases), hypothyroidism (one case), rheumatoid arthritis (one case), external ear canal basal carcinoma (one case). Although there is controversy regarding the relationship between GAD and associated diseases, it is accepted that it is significantly associated with diabetes mellitus, also found in our study in five out of eight cases. We noticed obvious improvements after local and general treatment. It is confirmed that GAD is prevalent in women, over 40-year-old. GAD is often associated with diabetes and dyslipidemia, therefore it is necessary to investigate patients in this direction. The histopathological exam is essential for an accurate confirmation of GA. PMID

    Motavasseli, M.

    1982-01-01

    This study provides historical background on, and explores the philosophy, motivation and nature of, capital movement in general and the role of multinational oil companies in European countries in particular. Also, theoretical and statistical models are developed to determine the major factors affecting the flow of foreign direct investment and to analyze the economic impact of this flow. The study concludes that there are many quantitative as well as non-quantitative factors of various socio-economic and political natures that determine the flows of direct investment abroad. The empirical results, based on yearly data for the period of 1950 to 1979, indicate that, among many variables tested in the model, seven are statistically significant in determining the amount of US direct investment abroad. These variables are: the level of output produced by the affiliates of the US companies in host countries, the US interest rate, retained earnings by the affiliates of the US companies, size of the host market, tariff discrimination, wage differentials and growth of the host market. On the question of the welfare effect of foreign direct investment, it is concluded that developed host nations tend to gain more from foreign direct investment than do other less-developed host countries.

  15. Case study in psychobiographical ethics.

    PubMed

    Ponterotto, Joseph G

    2013-10-01

    This article addresses ethical issues relative to the conduct and reporting of psychobiographical research. The author's recent psychobiographical study of World Chess Champion Bobby Fischer (1943-2008) is used to illustrate particular ethical challenges and responses in six areas: (1) institutional review board (IRB) evaluation and informed consent; (2) balancing objective research with respect for psychobiographical subject; (3) inviting subject or next-of-kin to read and comment on working drafts of psychobiography; (4) reporting never-before-revealed sensitive information on a subject; (5) role of interdisciplinary consultation in conducting psychobiography; and (6) the value and cautions of including psychological diagnoses as part of the psychological profile. A "bill of rights and responsibilities" for the psychobiographer is introduced as a stimulus for ongoing discussion and empirical research on ethical practice in psychobiography. PMID:24169418

    PubMed Central

    Alemayehu, Biruk; Kozusko, Steven D.; Borao, Frank; Vates III, Thomas S.

    2016-01-01

    Background. Polyorchidism, alternatively supernumerary testes (SNT), is a condition where an individual is born with more than two testicles. This congenital anomaly is quite rare and the literature has described various presentations. Questions/Purposes. To our knowledge, this presentation of polyorchidism has yet to be described in the literature. The goal of this case study is to add to the pediatric, general, and urologic surgery's body of knowledge of the subject matter. Case Study. A nine-month-old boy was admitted for an impalpable right testis and phimosis. At the time of surgical exploration, there appeared to be polyorchid testis on the right-hand side, with three masses that potentially appeared to be undescended testes. Discussion. Proponents of a conservative approach argue that infertility is common in patients with polyorchidism and, by preserving a potentially functional SNT, there may be improved spermatogenesis. When performing definitive surgical treatment, meticulous intra-abdominal and intrainguinal exploration must be undertaken. Orchiopexy should be performed to reduce the chances of torsion, malignancy, and infertility. Conclusion. Our case is important to the literature as it is the first known case of polyorchidism with 3 SNT on the right side, located intra-abdominally, and in a patient less than 1 year of age.

  20. Estimating the economic impacts of ecosystem restoration—Methods and case studies

    USGS Publications Warehouse

    Cullinane Thomas, Catherine; Huber, Christopher; Skrabis, Kristin; Sidon, Joshua

    2016-04-05

    This analysis estimates the economic impacts of a wide variety of ecosystem restoration projects associated with U.S. Department of the Interior (DOI) lands and programs. Specifically, the report provides estimated economic impacts for 21 DOI restoration projects associated with Natural Resource Damage Assessment and Restoration cases and Bureau of Land Management lands. The study indicates that ecosystem restoration projects provide meaningful economic contributions to local economies and to broader regional and national economies, and, based on the case studies, we estimate that between 13 and 32 job-years4 and between $2.2 and $3.4 million in total economic output5 are contributed to the U.S. economy for every $1 million invested in ecosystem restoration. These results highlight the magnitude and variability in the economic impacts associated with ecosystem restoration projects and demonstrate how investments in ecosystem restoration support jobs and livelihoods, small businesses, and rural economies. In addition to providing improved information on the economic impacts of restoration, the case studies included with this report highlight DOI restoration efforts and tell personalized stories about each project and the communities that are positively affected by restoration activities. Individual case studies are provided in appendix 1 of this report and are available from an online database at https://www.fort.usgs.gov/economic-impacts-restoration.

  4. Inconsistent Investment and Consumption Problems

    SciTech Connect

    Kronborg, Morten Tolver; Steffensen, Mogens

    2015-06-15

    In a traditional Black–Scholes market we develop a verification theorem for a general class of investment and consumption problems where the standard dynamic programming principle does not hold. The theorem is an extension of the standard Hamilton–Jacobi–Bellman equation in the form of a system of non-linear differential equations. We derive the optimal investment and consumption strategy for a mean-variance investor without pre-commitment endowed with labor income. In the case of constant risk aversion it turns out that the optimal amount of money to invest in stocks is independent of wealth. The optimal consumption strategy is given as a deterministic bang-bang strategy. In order to have a more realistic model we allow the risk aversion to be time and state dependent. Of special interest is the case were the risk aversion is inversely proportional to present wealth plus the financial value of future labor income net of consumption. Using the verification theorem we give a detailed analysis of this problem. It turns out that the optimal amount of money to invest in stocks is given by a linear function of wealth plus the financial value of future labor income net of consumption. The optimal consumption strategy is again given as a deterministic bang-bang strategy. We also calculate, for a general time and state dependent risk aversion function, the optimal investment and consumption strategy for a mean-standard deviation investor without pre-commitment. In that case, it turns out that it is optimal to take no risk at all.

    Steve Wiese, Terry Allison

    2000-09-01

    OAK-B135 The NWCC Transmission Case Studies Conclusions Summary In the spring of 1999, the Utility Wind Interest Group (UWIG), with the cooperation of the National Wind Coordinating Committee (NWCC), conducted a forum on transmission issues associated with the production of energy from wind. As a result of this forum, a number of issues were identified which, if successfully resolved, could help reduce barriers to the future expansion of wind power. The NWCC, being a multi-stakeholder group, was in an ideal position to conduct follow-up activities among a cross-section of the interested parties. The follow-up activities took the form of three case studies in the areas of interest identified by forum participants: (1) Transmission policy and pricing; (2) ''Virtual wheeling'' arrangements; and, (3) Transmission system improvements. The case studies provide an interesting snapshot in time dealing with a range of issues associated with scheduled or planned regulatory and restructuring proceedings related to energy transmission. The NWCC Transmission Subcommittee and the UWIG reviewed early drafts of the case studies in November 1999. The case studies were conducted through a questionnaire and interview process with interested parties. In writing each case study, NWCC staff attempted to identify all stakeholder groups with an interest in each topic and solicit their input. While all parties do not agree on every issue presented, a serious effort has been made to present all views in an unbiased fashion. At the end of each case study, relevant conclusions are drawn and recommendations for next steps are provided where appropriate.

    2012-01-01

    Background Radiotherapy is among the most efficient treatment methods of cancer. However, a radiotherapy base needs a substantial financial investment, especially before the beginning of its operation, and in some cases, in developing countries such a huge investment may cause some financial disturbances for a hospital concerned. Aim To assess the influence of investments modernizing the radiotherapy base in the period between 2000 and 2007 on the financial condition of the oncology hospital in the region with population of about 3 million. Material and methods Financial reports and medical statistics for the period between 2000 and 2007 from the studied oncology hospital and a recognized staffing model, as well as data on epidemiological situation of the region have been used to calculate the economic effects of financial investment in the radiotherapy base. Results The growth of RT therapeutic potential has been driven by two cost-effective investment programmes. The total amount invested in both programmes was PLN 127,191,000. The number of radiotherapy patients treated in the hospital increased from 2301 in 2000 to 4799 in 2007 with a the same number of five therapeutic machines, although all five of them were replaced over that period. Investments modernizing the radiotherapy base lead to a significant increase in depreciation and operating costs, which adversely affects financial results of the hospital. Conclusion Long term trends showed that investments had positive influence on hospital performance shown both in increased income and larger number of patients treated. PMID:24377017

  9. Concession length and investment timing flexibility

    NASA Astrophysics Data System (ADS)

    D'Alpaos, Chiara; Dosi, Cesare; Moretto, Michele

    2006-02-01

    When assigning a concession contract, the regulator faces the issue of setting the concession length. Another key issue is whether or not the concessionaire should be allowed to set the timing of new investments. In this paper we investigate the impact of concession length and investment timing flexibility on the "concession value." It is generally argued that long-term contracts are privately valuable as they enable a concessionaire to increase its overall discounted returns. Moreover, the real option theory suggests that investment flexibility has an intrinsic value, as it allows concessionaires to avoid costly errors. By combining these two conventional wisdoms one may argue that long-term contracts, which allow for investment timing flexibility, should always result in higher concession values. Our result suggests that this is not always the case; that is, investment flexibility and long-term contracts do not necessarily increase the concession value.

    2015-01-01

    Background: Increased workload, case complexity, financial constraints, and staffing shortages justify wider implementations of digital pathology. One of its main advantages is distance reporting. Aim: A feasibility study was conducted at our institution in order to achieve comprehensive pathology services available by distance. Methods: One senior pathologist reported 950 cases (3,650 slides) by distance during 19 weeks. Slides were scanned by ScanScope AT Turbo (Aperio) and digital images accessed through SymPathy (Tieto) on a 14” laptop. Mobile phone, mobile broadband, broadband over Wi-Fi and broadband were used for internet connections along with a virtual private network technology (VPN). Lync (Microsoft) was tested for one case consultation and resident's teaching session. Larger displays were accessed when available. Effects of ergonomics and working flexibility on the user experience were observed. Details on network speed, frequency of technical issues, data usage, scanning, and turnaround, were collected and evaluated. Turnaround was compared to in-office microscopic reporting, measured from the registration to sign off. Results: Network speeds varied 1–80 Mbps (median download speed 8–65 Mbps). 20 Mbps were satisfactory for the instant upload of digital images. VPN, image viewer, and laptop failed on two occasions each. An estimated data usage per digital image was 10 MB (1–50 MB). Two cases (15 slides) were deferred to microscopic slides (0.21/0.41%) due to scanty material and suboptimal slide quality. Additional nine cases (15 slides) needed to be rescanned for various reasons (0.95/0.41%). Average turnaround was shorter, and the percentage of cases reported up to 3 days higher (3.13 days/72.25%) comparing with in-office microscopic reporting (3.90 days/40.56%). Larger displays improved the most user experience at magnifications over ×20. Conclusions: Existing IT solutions at our institution allow efficient and reliable distance reporting for

    1990-10-01

    The following case studies demonstrate the application of self-assessment techniques. The selection of procedures reported here is not meant to imply necessarily that these procedures are more or less effective or more widely used than other available self-assessment tests, but rather to illustrate the various purposes for which self-assessment tools may be employed. Case 1 illustrates the contribution of data obtained from the Hearing Performance Inventory (Giolas, Owens, Lamb, & Shubert, 1979) in the management and counseling of a severely hearing impaired adult. Case 2 involves the use of the Hearing Problem Inventory developed by Hutton in Atlanta (HPI-A, Hutton, 1987). Application of the Self-Assessment of Communication (SAC) and Significant Other Assessment of Communication (SOAC) (Schow and Nerbonne, 1982) is shown in Case 3, whereas Case 4 demonstrates the usefulness of the Hearing Handicap Inventory for the Elderly (HHIE, Ventry and Weinstein, 1982). Both the SAC/SOAC and HHIE batteries involve problem cases associated with hearing aid fitting and assessment of benefit. The final illustration (Case 5) is a report on the Children's Auditory Processing Performance Scale (CHAPPS), a new questionnaire developed by Smoski, Brunt, and Tannahill/ISHA (1987) for assessing parent's judgment of children's listening abilities (Appendix). The versatility of self-assessment applications across a broad assortment of impairment levels, age groups, and clinical settings is demonstrated in these cases. Hopefully the reader will see more clearly the application and value of these and other non-audiometric techniques and will be motivated to increase the use of self-assessment tools in the individual work setting.

    O'Brien, Blake Hugh; McClymont, Kelly; Brown, Ian

    2011-08-01

    Collagenous ileitis (CI), characterized by subepithelial collagen deposition in the terminal ileum, is an uncommon condition. The few cases reported to date have been associated with collagenous colitis (CC) or lymphocytic colitis. Thirteen cases of CI retrieved over a 9-year period were retrospectively studied. There were 7 female and 6 male patients, with an age range of 39 to 72 years (mean, 64 y). Two groups were identified: (1) CI associated with collagenous or lymphocytic disease elsewhere in the gastrointestinal tract and (2) CI as an isolated process. Diarrhea was the presenting symptom in 11 cases. Most patients had no regular medication use. Subepithelial collagen thickness ranged from 15 to 100 μm (mean, 32 μm) and involved 5% to 80% of the subepithelial region of the submitted biopsies. Six cases had >25 intraepithelial lymphocytes (IELs)/100 epithelial cells, and villous blunting was observed in 11 cases. Chronic inflammation of the lamina propria was present in 9 cases, and focal neutrophil infiltration was identified in 3 cases. In biopsies taken from other sites, 7 of 13 colonic biopsies showed CC, 4 of 9 gastric biopsies showed collagenous gastritis, and 2 of 10 duodenal biopsies were abnormal with collagenous sprue (n=1) and partial villous atrophy and increased IELs (n=1) (both celiac disease related). Resolution of the subepithelial collagen deposition was found in the 1 case in which follow-up of terminal ileal biopsies were taken. There was partial or complete resolution of symptoms in 6 of 9 patients for whom follow-up information was available. PMID:21716082

    Meningitis and/or encephalitis can pose a serious public health problem especially during outbreaks. A rapid and accurate diagnosis is important for effective earlier treatment. This study aimed to identify the possible microbial causes of meningitis and/or encephalitis cases. CSF and serum samples were collected from 322 patients who had signs and symptoms suggestive of meningitis and/or encephalitis. Out of 250 cases with confirmed clinical diagnosis, 83 (33.2%) were definitely diagnosed as bacterial meningitis and/or encephalitis cases (by using CSF culture, biochemical tests, latex agglutination test, and CSF stain), 17 (6.8%) were definitely diagnosed as having viral causes ( by viral isolation on tissue culture, PCR and ELISA), and one (0.4%) was diagnosed as fungal meningitis case (by India ink stain, culture, and biochemical tests). Also, there was one encephalitis case with positive serum ELISA IgM antibodies against Sandfly scilian virus. N. meningitidis, S. pneumonia and M. tuberculosis were the most frequently detected bacterial agents, while Enteroviruses, herpes simplex viruses and varicella zoster viruses were the most common viral agents encountered. Further studies are needed to assess the role of different microbial agents in CNS infections and their effective methods of diagnosis.

  15. Investment in Green Technologies

    NASA Astrophysics Data System (ADS)

    Das Gupta, Supratim

    aggregate use of the natural resource is seen to not affect the behavior of an individual firm whereas it significantly affects that of the social planner. For relatively low pollution cost values, the socially optimal solution involves less investment in the backstop and conserving the natural resource for a longer period compared to the case without pollution. For higher values of the pollution cost, the social planner invests more in the backstop each period and switches sooner to the backstop compared to the case without pollution. In some situations, this may involve leaving behind some stock of the natural resource in the ground. The third chapter introduces pollution (a stock variable) through a deterioration of environmental quality. The structure of the second chapter is maintained here. Comparing the true pollution cost of the resource (in terms of a poor environmental quality) and the cost of the backstop technology, it is possible for the natural resource to be relatively more expensive. This arises in a situation of a very dirty environmental quality where the additional benefit from a slightly better environment exceeds the cost of the alternative cleaner technology. In this case, the optimal solution involves using the backstop at first for a few periods before making a discrete jump to a constant mix of using both the resource and the backstop technology. Here the economy settles at a steady state of environmental quality. It similarly follows that when the quality of the environment is relatively clean to begin with, the optimal solution involves starting with the cheaper but polluting natural resource before switching to a constant mix of using both the energy sources.

  18. Acoustical case studies of three green buildings

    NASA Astrophysics Data System (ADS)

    Siebein, Gary; Lilkendey, Robert; Skorski, Stephen

    2005-04-01

    Case studies of 3 green buildings with LEED certifications that required extensive acoustical retrofit work to become satisfactory work environments for their intended user groups will be used to define areas where green building design concepts and acoustical design concepts require reconciliation. Case study 1 is an office and conference center for a city environmental education agency. Large open spaces intended to collect daylight through clerestory windows provided large, reverberant volumes with few acoustic finishes that rendered them unsuitable as open office space and a conference room/auditorium. Case Study 2 describes one of the first gold LEED buildings in the southeast whose primary design concepts were so narrowly focused on thermal and lighting issues that they often worked directly against basic acoustical requirements resulting in sound levels of NC 50-55 in classrooms and faculty offices, crosstalk between classrooms and poor room acoustics. Case study 3 is an environmental education and conference center with open public areas, very high ceilings, and all reflective surfaces made from wood and other environmentally friendly materials that result in excessive loudness when the building is used by the numbers of people which it was intended to serve.

  10. Recurrent perinatal loss: a case study.

    PubMed

    Kavanaugh, K; Robertson, P A

    1999-01-01

    To date, investigators have not demonstrated a clear relationship between a parent's history of prior perinatal losses and intensity of grief response following a subsequent perinatal loss. Examining this relationship for low-income, African-American parents is important because they are a vulnerable population due to the high incidence of perinatal mortality in Blacks and their other life stressors that can impact on grief response and caring needs. The purpose of this case study was to examine the impact of recurrent perinatal loss on a low-income African-American parent. The research design for this study was case report, using interview data collected from a mother who had recently experienced her fourth perinatal loss, which occurred at twenty-five weeks of gestation. Transcripts from two open-ended interviews were analyzed. The theoretical framework used to guide analysis of this case study was Lazarus and Folkman's stress and coping theory. Results demonstrated that the prior perinatal losses did not appear as critical components of the way the mother responded to her most recent loss. Instead, perception of the care she received from healthcare providers and how that care related to her experiences with her one living child who was born at the same gestational age was an important determinant in how she responded to her loss. The results of this case study demonstrate the importance assessing a person's perception of their experience and those factors which contribute to the way they respond.

    Multiple observational studies have demonstrated associations of psoriasis with metabolic syndrome including obesity, diabetes, hypertension, dyslipidemia, and osteoporosis. However there is paucity of Indian studies on dyslipidemia in psoriasis. The aim of this study was to assess the serum lipids in psoriasis and to investigate the association of lipids with disease severity and its duration. 100 cases of psoriasis (75/M, 25/F), between 15 and 72 years, were recruited with age and sex matched 73 controls. Using Psoriasis Area Severity Index (PASI) cases were graded into mild, moderate, and severe psoriasis. Serum total cholesterol and triglycerides were analyzed using enzymatic method. Using independent t-test, significant elevation of serum cholesterol, triglycerides, high density lipoprotein (HDL) and very low density lipoprotein was observed (P < 0.05) when compared to controls. The levels of low density lipoproteins were comparable in cases and controls. Lipid aberrations in hypertensive patients were significant. There was a decrease in HDL levels with increase in disease severity. A fall in the levels of HDL was seen in cases with long term psoriasis. There is a strong association of dyslipidemia with psoriasis. There exist racial and ethnic variation in the prevalence of psoriasis; however, dyslipidemia is consistently seen in diverse population. Whether genetic factors are implicated in lipid derangements in psoriasis needs further research. PMID:27433517

  10. Seismic damage to pipeline; Case study

    A case study of damage to a welded steel pipeline in Mexico City, caused by the 1985 Michoacan earthquake, is presented. Seismic damage to pipelines in past earthquakes is briefly reviewed. The damage has typically been due to seismic wave propagation or permanent ground deformations, such as faulting, landslides, or lateral spreads. Physical characteristics of the case study pipeline, pertinent soil conditions, recorded ground motion, and observed seismic damage in Mexico City are then presented. The recorded ground motion in the lake zone of Mexico City suggests a significant contribution from Rayleigh waves. A previously developed analysis procedure is used to estimate stress induced by seismic wave propagation in the case study pipeline. The pipeline stress is a function of the amplitude and wavelength of the ground strain, maximum friction forces at the soil-pipe interface, and the stress-strain characteristics of the pipeline material. It is shown that the estimated stress is only slightly less than the local compressional buckling stress for the case history pipeline.

    Case studies of 11 leading integrated delivery systems (IDSs) found all of these organizations are committed to investing in the development of sophisticated IT systems. The case-study IDSs' primary concerns regarding IT investments were related to achieving adequate financial and patient care returns, accessing capital, finding qualified IT staff, finding reliable IT vendors, achieving physician acceptance, and sharing software and IT solutions with other IDSs. Among the competitive advantages these IDSs have gained from advanced IT capabilities are improved patient satisfaction due to superior service outcomes and the IDS's ability to access clinical information from any point within its delivery system, reduced prescription errors and adverse drug reactions, enhanced quality-improvement efforts, reduced costs associated with telephone calls and paper processing, and enhanced ability to recruit clinical personnel.

    Large, multinational resource development projects can affect many aspects, including social, economic and ecological realities, in the regions where they operate. Social and environmental issues that are usually ignored in such projects are increasingly affecting the financial future of multinational corporations in negative ways. In this article, we advance the argument that corporations can successfully manage these issues and that if they choose to view these management efforts as an investment rather than an expense, they may well acquire a competitive advantage over companies that do not. We describe as a case study the Camisea natural gas and condensates development project in Peru, operated by Shell Prospecting and Development Peru (SPDP). Camisea is one of the first projects anywhere in the world to conduct a detailed analysis of key industry-related social issues and the processes, required investment and financial impact of managing them. The Camisea example supports the argument that addressing social and environmental concerns makes financial sense. In present value terms, the benefit of managing these concerns was expected to surpass the cost investment by approximately US$50 million. PMID:12125747

    Pilomatricoma is a common and benign skin tumor of childhood arising from the hair follicle matrix. It is an often misunderstood adnexal tumor, confused with other skin lesions. The most common sites of pilomatricome are the head and the neck. The aim of this study was to report a series of 22 cases with unusual forms collected in the dermatology department from January 2006 to May 2015. The study included 16 women and 6 men. The average age was 23.3 years (4- 80 years). Cervicofacial location was observed in 12 cases, 2 patients had multiple locations, a 4 year-old boy had frontotemporal location, a 14 year-old girl had face and forearm location and a 48 year-old patient had subungual location. Clinical features were typical in all cases, with subcutaneous nodules with a stony-hard consistency. All patients underwent excision of nodules under local anesthesia. Histological study supported a completely excised Malherbe's mummified tumor without malignancy. No patients relapsed. The originality of our study lies in the presence of exceptional locations in laterovertebral region, on limbs and in the subungual region and of unusual age of onset (80 year-old) as well as the presence of multiple tumor locations reported in 2 children.

    In Portugal, there is an increase of costs in the healthcare sector due to several factors such as the aging of the population, the increased demand for health care services and the increasing investment in new technologies. Thus, there is a need to reduce costs, by presenting the effective and efficient management of logistics supply systems with enormous potential to achieve savings in health care organizations without compromising the quality of the provided service, which is a critical factor, in this type of sector. In this research project the implementation of Advanced Warehouses has been studied, in the Hospital de Braga patient care units, based in a mix of replenishment systems approaches: the par level system, the two bin system and the consignment model. The logistics supply process is supported by information technology (IT), allowing a proactive replacement of products, based on the hospital services consumption records. The case study was developed in two patient care units, in order to study the impact of the operation of the three replenishment systems. Results showed that an important inventory holding costs reduction can be achieved in the patient care unit warehouses while increasing the service level and increasing control of incoming and stored materials with less human resources. The main conclusion of this work illustrates the possibility of operating multiple replenishment models, according to the types of materials that healthcare organizations deal with, so that they are able to provide quality health care services at a reduced cost and economically sustainable. The adoption of adequate IT has been shown critical for the success of the project.

    Supercentenarians (aged 110 years old or more) are extremely rare in the world population (the number of living supercentenarians is estimated as 47 in the world), and details about their neuropathological information are limited. Based on previous studies, centenarians (aged 100-109 years old) exhibit several types of neuropathological changes, such as Alzheimer's disease and Lewy body disease pathology, primary age-related tauopathy, TDP-43 pathology, and hippocampal sclerosis. In the present study, we provide results from neuropathological analyses of four supercentenarian autopsy cases using conventional and immunohistochemical analysis for neurodegenerative disorders. In particular, we focused on the pathology of Alzheimer's disease and Lewy body disease, as well as the status of hippocampal sclerosis, TDP-43 pathology, aging-related tau astrogliopathy, and cerebrovascular diseases. Three cases were characterized as an "intermediate" level of Alzheimer's disease changes (NIA-AA guideline) and one was characterized as primary age-related tauopathy. TDP-43 deposits were present in the hippocampus in two cases. Neither Lewy body pathology nor hippocampal sclerosis was observed. Aging-related tau astrogliopathy was consistently observed, particularly in the basal forebrain. Small vessel diseases were also present, but they were relatively mild for cerebral amyloid-beta angiopathy and arteriolosclerosis. Although our study involved a small number of cases, the results provide a better understanding about human longevity. Neuropathological alterations associated with aging were mild to moderate in the supercentenarian brain, suggesting that these individuals might have some neuroprotective factors against aging. Future prospective studies and extensive molecular analyses are needed to determine the mechanisms of human longevity. PMID:27590044

    A case-study collection was developed for NASA's Space Shuttle Program. Using lessons learned and documented by NASA KSC engineers, analysts, and contractors, decades of information related to processing and launching the Space Shuttle was gathered into a single database. The goal was to provide educators with an alternative means to teach real-world engineering processes and to enhance critical thinking, decision making, and problem solving skills. Suggested formats were created to assist both external educators and internal NASA employees to develop and contribute their own case-study reports to share with other educators and students. Via group project, class discussion, or open-ended research format, students will be introduced to the unique decision making process related to Shuttle missions and development. Teaching notes, images, and related documents will be made accessible to the public for presentation of Space Shuttle reports. Lessons investigated included the engine cutoff (ECO) sensor anomaly which occurred during mission STS-114. Students will be presented with general mission infom1ation as well as an explanation of ECO sensors. The project will conclude with the design of a website that allows for distribution of information to the public as well as case-study report submissions from other educators online.

    OBJECTIVE. This study explores the relationship between quality of care and investment in property, plant, and equipment (PPE) in hospitals. DATA SOURCES. Hospitals' investment in PPE was derived from audited financial statements for the fiscal years 1984-1989. Peer Review Organization (PRO) Generic Quality Screen (GQS) reviews and confirmed failures between April 1989 and September 1990 were obtained from the Massachusetts PRO. STUDY DESIGN. Weighted least squares regression models used PRO GQS confirmed failure rates as the dependent variable, and investment in PPE as the key explanatory variable. DATA EXTRACTION. Investment in PPE was standardized, summed by the hospital over the six years, and divided by the hospital's average number of beds in that period. The number of PRO reviewed cases with one or more GQS confirmed failures was divided by the total number of cases reviewed to create confirmed failure rates. PRINCIPAL FINDINGS. Investment in PPE in Massachusetts hospitals is correlated with GQS confirmed failure rates. CONCLUSIONS. A financial variable, investment in PPE, predicts certain dimensions of quality of care in hospitals. PMID:8113054

    The Global Hydrology and Climate Center and NASA's Marshall Space Flight Center conducted a fact-finding case study for the Data Management Working Group (DMWG), now referred to as the Data and Information Working Group (DIWG), of the U.S. Global Change Research Program (USGCRP) to determine the feasibility of an interagency National Environmental Change Information System (NECIS). In order to better understand the data and information needs of policy and decision makers at the national, state, and local level, the DIWG asked the case study team to choose a regional water resources issue in the southeastern United States that had an impact on a diverse group of stakeholders. The southeastern United States was also of interest because the region experiences interannual climatic variations and impacts due to El Nino and La Nina. Jointly, with input from the DIWG, a focus on future water resources planning in the Apalachicola-Chattahoochee-Flint (ACF) River basins of Alabama, Georgia, and Florida was selected. A tristate compact and water allocation formula is currently being negotiated between the states and U.S. Army Corps of Engineers (COE) that will affect the availability of water among competing uses within the ACF River basin. All major reservoirs on the ACF are federally owned and operated by the U.S. Army COE. A similar two-state negotiation is ongoing that addresses the water allocations in the adjacent Alabama-Coosa-Tallapoosa (ACT) River basin, which extends from northwest Georgia to Mobile Bay. The ACF and ACT basins are the subject of a comprehensive river basin study involving many stakeholders. The key objectives of this case study were to identify specific data and information needs of key stakeholders in the ACF region, determine what capabilities are needed to provide the most practical response to these user requests, and to identify any limitations in the use of federal data and information. The NECIS case study followed the terms of reference

    Isosurface extraction is an important and useful visualization method. Over the past ten years, the field has seen numerous isosurface techniques published leaving the user in a quandary about which one should be used. Some papers have published complexity analysis of the techniques yet empirical evidence comparing different methods is lacking. This case study presents a comparative study of several representative isosurface extraction algorithms. It reports and analyzes empirical measurements of execution times and memory behavior for each algorithm. The results show that asymptotically optimal techniques may not be the best choice when implemented on modern computer architectures.

It also improves oral and written communication, analytical skills and synthesis and also the ability to think critically. Biomaterials have their origin in biominerals. These are solid inorganic compounds of defined structure, consisting of molecular control mechanisms that operate in biological systems. Its main functions are: structural support, a reservoir of essential elements, sensors, mechanical protection and storage of toxic elements. Following the demand of materials compatible with certain functional systems of our body, developed biomaterials. Always meet the condition of biocompatibility. Should be tolerated by the body and do not provoke rejection. This involves a comprehensive study of physiological conditions and the anatomy of the body where a biomaterial has to be implemented. The possibility of generating new materials from biominerals has a major impact in medicine and other fields could reach as geology, construction, crystallography, etc. While the study of these issues is in its infancy today, can be viewed as an impact on the art and future technology. Planning case study that students would prepare its report for discussion in subgroups. Occurs then the pooling of individual analysis, joint case discussion and adoption by the subgroup of a consensual solution to the problem. The teacher as facilitator and coordinator of the final case analysis, sharing leads to group-wide class and said the unanimous decision reached by the students and gives his opinion on the resolution of the case.

    Terahertz (THz) spectroscopy and imaging is a non-destructive, non-contact, non-invasive technology emerging as a tool for the analysis of cultural heritage. THz Time Domain Spectroscopy (TDS) techniques have the ability to retrieve information from different layers within a stratified sample, that enable the identification of hidden sub-layers in the case of paints and mural paintings. In this paper, we present the THz TDS2 system developed in the European Commission's 7th Framework Program project CHARISMA [grant agreement no. 228330]. Bespoke single processing algorithms; including a deconvolution algorithm can be deployed to increase the resolution and the global performance of the system. The potential and impact of this work is demonstrated through two case studies of mural paintings, where the capability to reveal the stratigraphy of the artworks is demonstrated.

  17. Socially responsible investing. Is it successful?

    PubMed

    Camey, B F

    1994-11-01

    Socially responsible investing (SRI) has been defined as "the integration of social or ethical criteria into the investment decision-making process." Based on the values they hold, investors distinguish socially responsible investments from those which are not by implementing social screens: nonfinancial criteria applied in the decision-making process. Socially responsible investors typically follow one of three approaches to ethical investing: avoidance of businesses whose activities they do not support, a positive approach where they seek investments that will enhance the quality of life, and an activist approach where they attempt to influence the company's activities. In addition to individuals, many institutional investors are heavily involved with SRI. Activist investors can judge their investments' performance by the success of their shareholder activities. Investors might also look at the societal effects of their investments. If investors are seeking to change the corporation or society, SRI has proven to be successful. Empirical studies have shown mixed results with respect to the financial performance of SRI, but the findings tend to show that SRI has minimal impact, either positively or negatively, on investment returns. Nevertheless, many factors indicate that SRI may be here to stay. PMID:10137947

  19. Farmers' use of nutrient management: lessons from watershed case studies.

    Nutrient enrichment of water resources has degraded coastal waters throughout the world, including in the United States (e.g., Chesapeake Bay, Gulf of Mexico, and Neuse Estuary). Agricultural nonpoint sources have significant impacts on water resources. As a result, nutrient management planning is the primary tool recommended to reduce nutrient losses from agricultural fields. Its effectiveness requires nutrient management plans be used by farmers. There is little literature describing nutrient management decision-making. Here, two case studies are described that address this gap: (i) a synthesis of the National Institute of Food and Agriculture, the Conservation Effects Assessment Project, and (ii) field surveys from three nutrient-impaired river basins/watersheds in North Carolina (Neuse, Tar-Pamlico, and Jordan Lake drainage areas). Results indicate farmers generally did not fully apply nutrient management plans or follow basic soil test recommendations even when they had them. Farmers were found to be hesitant to apply N at university-recommended rates because they did not trust the recommendations, viewed abundant N as insurance, or used recommendations made by fertilizer dealers. Exceptions were noted when watershed education, technical support, and funding resources focused on nutrient management that included easing management demands, actively and consistently working directly with a small group of farmers, and providing significant resource allocations to fund agency personnel and cost-share funds to farmers. Without better dialogue with farmers and meaningful investment in strategies that reward farmers for taking what they perceive as risks relative to nutrient reduction, little progress in true adoption of nutrient management will be made.

    Reinforcement Learning algorithms offer interesting features for the control of autonomous systems, such as the ability to learn from direct interaction with the environment, and the use of a simple reward signalas opposed to the input-outputs pairsused in classic supervised learning. The reward signal indicates the success of failure of the actions executed by the agent in the environment. In this work, are described RL algorithmsapplied to two case studies: the Crawler robot and the widely known inverted pendulum. We explore RL capabilities to autonomously learn a basic locomotion pattern in the Crawler, andapproach the balancing problem of biped locomotion using the inverted pendulum.

    Wildfire can result in significant losses to people and property. Management agencies undertake a range of actions in the landscape and at the interface to reduce this risk. Data relating to the success of individual treatments varies, with some approaches well understood and others less so. Research has rarely attempted to consider the interactive effects of treatments in order to determine optimal management strategies that reduce the risk of loss. Bayesian Networks provide a statistical framework for undertaking such an analysis. Here we apply Bayesian Networks to examine the trade-offs in investment in preventative actions (e.g., fuel treatment, community education, development controls) and suppressive actions (e.g., initial attack, landscape suppression, property protection) in two fire prone regions -Sydney, Australia and California, USA. Investment in management actions at the interface resulted in the greatest reduction in the risk of house loss for both of the study regions. Landscape treatments had a limited ability to change the risk of house loss.

  6. The case for investing in family planning in the Pacific: costs and benefits of reducing unmet need for contraception in Vanuatu and the Solomon Islands

    2013-01-01

    Background Unmet need for family planning in the Pacific is among the highest in the world. Better understanding of required investments and associated benefits of increased access to family planning in the Pacific may assist prioritisation and funding. Methods We modelled the costs and associated health, demographic and economic impacts of reducing unmet need for family planning between 2010–2025 in Vanuatu and the Solomon Islands. Baseline data were obtained from census reports, Demographic and Health Surveys, and UN agency reports. Using a demographic modelling program we compared a scenario of “no change in unmet need” with two distinct scenarios: 1) all family planning needs met by 2020; and, 2) all needs met by 2050. Results Meeting family planning needs by 2020 would increase prevalence of modern contraception in 2025 from 36.8 to 65.5% in Vanuatu and 28.5 to 37.6% in the Solomon Islands. Between 2010–2025 the average annual number of unintended pregnancies would decline by 68% in Vanuatu and 50% in the Solomon Islands, and high-risk births would fall by more than 20%, averting 2,573 maternal and infant deaths. Total fertility rates would fall from 4.1 to 2.2 in Vanuatu and 3.5 in the Solomon Islands, contributing to slowed population growth and lower dependency ratios. The direct cost of reducing unmet need by 2020 was estimated to be $5.19 million for Vanuatu and $3.36 million for the Solomon Islands between 2010–2025. Preventing unintended pregnancies would save $112 million in health and education expenditure. Conclusions In small island developing states such as Vanuatu and the Solomon Islands, increasing investment in family planning would contribute to improved maternal and infant outcomes and substantial public sector savings.

    Rivers provide society with numerous returns. These relate to both the passive and extractive uses of the resources embodied in river environments. Some returns are manifest in the form of financial gains whilst others are non-monetary. For instance, rivers are a source of monetary income for those who harvest their fish. The water flowing in rivers is extracted for drinking and to water crops and livestock that in turn yield monetary profits. However, rivers are also the source of non-monetary values arising from biological diversity. People who use them for recreation (picnicking, swimming, boating) also receive non-monetary returns. The use of rivers to yield these returns has had negative consequences. With extraction for financial return has come diminished water quantity and quality. The result has been a diminished capacity of rivers to yield (non-extractive) environmental returns and to continue to provide extractive values. A river is like any other asset. With use, the value of an asset depreciates because its productivity declines. In order to maintain the productive capacity of their assets, managers put aside from their profits depreciation reserves that can be invested in the repair or replacement of those assets. Society now faces a situation in which its river assets have depreciated in terms of their capacity to provide monetary and non-monetary returns. An investment in river "repair" is required. But, investment means that society gives up something now in order to achieve some benefit in the future. Society thus has to grapple wih the choice between investing in river health and other investments--such as in hospitals, schools, defence etc. - as well as between investing in river health and current consumption--such as on clothes, food, cars etc. A commonly used aid for investment decision making in the public sector is benefit cost analysis.

    Abstract Within any professional practice, knowledge developments to support service delivery and to understand roles inherent within that practice context are critical. The purpose of this article is to present findings from case study research that used the AUSPRAC Research Toolkit Interview Schedule and to propose an additional theme to the Interview Schedule. Case Study method was used to explore the role of a nurse practitioner (NP) within a specific context of practice in an Australian Healthcare institution. Three semi-structured interviews with a NP using the AUSPRAC Research Toolkit Interview Schedule and one additional interview were employed. Data was analysed where initial free coding, then theme generation contributed to knowledge development. The AUSPRAC Research Toolkit Interview Schedule generated knowledge about the NP role. Themes identified for interviews in the Schedule were: the organisation of care, team functioning and patient service. Analysis of data from these themes identified that information related to ongoing development of professional practice was not forthcoming from the participant. The authors recommend adding a fourth theme to the Interview Schedule to enable exploration of the professional elements of the NP role.

    We conducted a one-year prospective study involving a prehospital Emergency Medical Service in the Netherlands to investigate the incidence of failed or difficult prehospital endotracheal intubation. During the study period the paramedics were asked to fill in a registration questionnaire after every endotracheal intubation. Of the 26,271 patient contacts, 256 endotracheal intubations were performed by paramedics in one year. Endotracheal intubation failed in 12 patients (4.8%). In 12.0% of 249 patients, a Cormack and Lehane grade III laryngoscopy was reported and a grade IV laryngoscopy was reported in 10.4%. The average number of endotracheal intubations per paramedic in one year was 4.2 and varied from zero to a maximum of 12. The median time between arrival on the scene and a positive capnograph was 7 min.38 s in the case of a Cormack and Lehane grade I laryngoscopy and 14 min.58 s in the case of a Cormack and Lehane grade 4 laryngoscopy. The incidence of endotracheal intubations performed by Dutch paramedics in one year was low, but endotracheal intubation was successful in 95.2%, which is comparable with findings in international literature. Early capnography should be used consistently in prehospital airway management. PMID:21612142

    California is the largest cement producing state in theU.S., accounting for between 10 percent and 15 percent of U.S. cementproduction and cement industry employment. The cement industry inCalifornia consists of 31 sites that consume large amounts of energy,annually: 1,600 GWh of electricity, 22 million therms of natural gas, 2.3million tons of coal, 0.25 tons of coke, and smaller amounts of wastematerials, including tires. The case study summarized in this paperfocused on providing background information, an assessment ofenergy-efficiency opportunities and barriers, and program recommendationsthat can be used by program planners to better target products to thecement industry. The primary approach to this case study involvedwalk-through surveys of customer facilities and in depth interviews withcustomer decision makers and subsequent analysis of collected data. Inaddition, a basic review of the cement production process was developed,and summary cement industry energy and economic data were collected, andanalyzed. The analysis of secondary data provides background informationon the cement industry and identification of potential energy-efficiencyopportunities. The interviews provide some understanding of the customerperspective about implementation of energy-efficiencyprojects.

    RTCA DO-333, Formal Methods Supplement to DO-178C and DO-278A provides guidance for software developers wishing to use formal methods in the certification of airborne systems and air traffic management systems. The supplement identifies the modifications and additions to DO-178C and DO-278A objectives, activities, and software life cycle data that should be addressed when formal methods are used as part of the software development process. This report presents three case studies describing the use of different classes of formal methods to satisfy certification objectives for a common avionics example - a dual-channel Flight Guidance System. The three case studies illustrate the use of theorem proving, model checking, and abstract interpretation. The material presented is not intended to represent a complete certification effort. Rather, the purpose is to illustrate how formal methods can be used in a realistic avionics software development project, with a focus on the evidence produced that could be used to satisfy the verification objectives found in Section 6 of DO-178C.

    1998-01-01

    There have been numerous reports in the literature on the descriptive similarities between a severe nightmare and an acute psychotic episode. Nightmares may be a prelude to psychotic decompensation, and it has been suggested that frequent lifelong nightmares may even be diagnostic of an underlying vulnerability to psychosis. In this report, we present a case study of a 40-year old female experiencing chronic paranoid schizophrenia, whose two witnessed psychotic relapses in the hospital were immediately preceded by intense and vivid nightmare attacks. Significantly, the content of these nocturnal dreams was thematically consistent with her waking hallucinations, suggesting a direct continuity between these experiences. We propose that further systematic study of the dreams and nightmares of individuals diagnosed with schizophrenia may be particularly useful in understanding their phenomenological experience.

    The scheduling in job shop is important for efficient utilization of machines in the manufacturing industry. There are number of algorithms available for scheduling of jobs which depend on machines tools, indirect consumables and jobs which are to be processed. In this paper a case study is presented for scheduling of jobs when parts are treated on available machines. Through time and motion study setup time and operation time are measured as total processing time for variety of products having different manufacturing processes. Based on due dates different level of priority are assigned to the jobs and the jobs are scheduled on the basis of priority. In view of the measured processing time, the times for processing of some new jobs are estimated and for efficient utilization of the machines available an algorithm is proposed and validated.

    Motivation: As the number of clinical reports in the peer-reviewed medical literature keeps growing, there is an increasing need for online search tools to find and analyze publications on patients with similar clinical characteristics. This problem is especially critical and challenging for rare diseases, where publications of large series are scarce. Through an applied example, we illustrate how to automatically identify new relevant cases and semantically annotate the relevant literature about patient case reports to capture the phenotype of a rare disease named cerebrotendinous xanthomatosis. Results: Our results confirm that it is possible to automatically identify new relevant case reports with a high precision and to annotate them with a satisfactory quality (74% F-measure). Automated annotation with an emphasis to entirely describe all phenotypic abnormalities found in a disease may facilitate curation efforts by supplying phenotype retrieval and assessment of their frequency.

    The research was conducted to two parts. Part one consisted of a study of the feasibility of running the Space Transportation Model simulation on an office IBM-AT. The second part was to design simulation runs so as to study the effects of certain performance factors on the execution of the simulation model. The results of this research are given in the two reports which follow: Microcomputer vs. Mainframe Simulation: A Case Study and Fractional Factorial Designs of Simulation Runs for the Space Transportation System Operations Model. In the first part, a DOS batch job was written in order to simplify the execution of the simulation model on an office microcomputer. A comparison study was then performed of running the model on NASA-Langley's mainframe computer vs. running on the IBM-AT microcomputer. This was done in order to find the advantages and disadvantages of running the model on each machine with the objective of determining if running of the office PC was practical. The study concluded that it was. The large number of performance parameters in the Space Transportation model precluded running a full factorial design needed to determine the most significant design factors. The second report gives several suggested fractional factorial designs which require far fewer simulation runs in order to determine which factors have significant influence on results.

    Measures aimed at conservation or restoration of ecosystems are often seen as net-cost projects by governments and businesses because they are based on incomplete and often faulty cost-benefit analyses. After screening over 200 studies, we examined the costs (94 studies) and benefits (225 studies) of ecosystem restoration projects that had sufficient reliable data in 9 different biomes ranging from coral reefs to tropical forests. Costs included capital investment and maintenance of the restoration project, and benefits were based on the monetary value of the total bundle of ecosystem services provided by the restored ecosystem. Assuming restoration is always imperfect and benefits attain only 75% of the maximum value of the reference systems over 20 years, we calculated the net present value at the social discount rates of 2% and 8%. We also conducted 2 threshold cum sensitivity analyses. Benefit-cost ratios ranged from about 0.05:1 (coral reefs and coastal systems, worst-case scenario) to as much as 35:1 (grasslands, best-case scenario). Our results provide only partial estimates of benefits at one point in time and reflect the lower limit of the welfare benefits of ecosystem restoration because both scarcity of and demand for ecosystem services is increasing and new benefits of natural ecosystems and biological diversity are being discovered. Nonetheless, when accounting for even the incomplete range of known benefits through the use of static estimates that fail to capture rising values, the majority of the restoration projects we analyzed provided net benefits and should be considered not only as profitable but also as high-yielding investments.

    Measured energy performance data are essential to national efforts to improve building efficiency, as evidenced in recent benchmarking mandates, and in a growing body of work that indicates the value of permanent monitoring and energy information feedback. This paper presents case studies of energy information systems (EIS) at four enterprises and university campuses, focusing on the attained energy savings, and successes and challenges in technology use and integration. EIS are broadly defined as performance monitoring software, data acquisition hardware, and communication systems to store, analyze and display building energy information. Case investigations showed that the most common energy savings and instances of waste concerned scheduling errors, measurement and verification, and inefficient operations. Data quality is critical to effective EIS use, and is most challenging at the subsystem or component level, and with non-electric energy sources. Sophisticated prediction algorithms may not be well understood but can be applied quite effectively, and sites with custom benchmark models or metrics are more likely to perform analyses external to the EIS. Finally, resources and staffing were identified as a universal challenge, indicating a need to identify additional models of EIS use that extend beyond exclusive in-house use, to analysis services.

    Many acceleration-sensitive, microgravity science experiments will require active vibration isolation from manned orbiters on which they will be mounted. The isolation problem, especially in the case of a tethered payload, is a complex three-dimensional one that is best suited to modern-control design methods. In this paper, extended H(sub 2) synthesis is used to design an active isolator (i.e., controller) for a realistic single-input-multiple-output (SIMO) microgravity vibration isolation problem. Complex mu-analysis methods are used to analyze the isolation system with respect to sensor, actuator, and umbilical uncertainties. The paper fully discusses the design process employed and the insights gained. This design case study provides a practical approach for isolation problems of greater complexity. Issues addressed include a physically intuitive state-space description of the system, disturbance and noise filters, filters for frequency weighting, and uncertainty models. The controlled system satisfies all the performance specifications and is robust with respect to model uncertainties.

    This project made a significant contribution to the understanding of the investment casting shell cracking problem. The effects of wax properties on the occurrence of shell cracking were demonstrated and can be measured. The properties measured include coefficient of thermal expansion, heating rate and crystallinity of the structure. The important features of production molds and materials properties have been indicated by case study analysis and fractography of low strength test bars. It was found that stress risers in shell cavity design were important and that typical critical flaws were either oversize particles or large pores just behind the prime coat. It was also found that the true effect of fugitive polymer fibers was not permeability increase, but rather a toughening mechanism due to crack deflection.

    Stephens, Shelly J

    2009-11-01

    In 1991, Amway formed an industrial hazardous materials (hazmat) team in order to respond quickly and efficiently to potential chemical spills. The company's goals were, and still are today, to protect employees, the environment and the local community, and to reduce the amount of resulting downtime. In 1991, the hazmat team was very well funded, enabling it to become a discrete department with its own management staff and nearly 100 hazmat volunteers. Due to changes in the business climate, Amway reorganised in 2000/01, and the hazmat team became part of a company that incorporated contract work into its scope. When this reorganisation occurred, the hazmat team was thoroughly re-evaluated. Its response function was maintained, but was systematically reinvented in the most lean way practicable while still meeting corporate goals. This case study represents Amway's hazmat team's journey through the evaluation process and subsequent reorganisation.

    Rates of survival after cardiac arrest are low and correlate with the quality of cardiopulmonary resuscitation (CPR). Devices that deliver automated CPR (A-CPR) can provide sustained and effective chest compressions, which are especially useful during patient transfer and while simultaneous invasive procedures are being performed. The use of such devices can also release members of resuscitation teams for other work. This article presents a case study involving a man with acute myocardial infarction complicated by cardiogenic shock and pulmonary oedema. It describes how ED nursing and medical teams worked together to deliver A-CPR, discusses the use of A-CPR devices in a tertiary cardiac centre, and highlights the advantages of using such devices.

    This paper focuses on three seemingly unrelated error patterns in the sound system of a child with a phonological delay, Child 218 (male, age 4 years 6 months) and ascribes those error patterns to a larger conspiracy to eliminate fricatives from the phonetic inventory. Employing Optimality Theory for its advantages in characterizing conspiracies, our analysis offers a unified account of the observed repairs. The contextual restrictions on those repairs are, moreover, attributed to early developmental prominence effects, which are independently manifested in another error pattern involving rhotic consonants. Comparisons are made with a published case study involving a different implementation of the same conspiracy, the intent being to disambiguate the force behind certain error patterns. The clinical implications of the account are also considered. PMID:25000372

    The LM2500+ industrial aeroderivative gas turbine, a 25% enhanced power derivative of the LM2500 gas turbine, recently completed its development test program during the period 5/96 - 10/96. Early in the engine program a Quality Function Deployment (QFD) process was used to determine customer needs for this project.The feedback obtained from the QFD process showed without doubt that gas turbine customers now emphasize product reliability and availability at the top of their needs. One area of development on the LM2500+ was to investigate the use of a brush seal as a means to reduce undesirable turbine cooling leakages within the turbine mid frame in order to enhance part life. This presentation presents a case study on the factors that went into evaluating a brush seal during engine test, test results, and the ultimate decision not to implement the brush seal for cost and other reasons.

    Outcome-based education is one of the most significant global developments in medical education in recent years. This paper presents four case studies of outcome-based education from medical schools in different parts of the world; Scotland; USA; Pakistan; and Singapore. The outcome-based curricula have either been in place for some time, are evolving or are at the planning proposal stage. The outcomes, change process and implementation of the outcome-based approach are described. Variation in the extent to which each medical school has implemented outcome-based education is discussed and key points for successful implementation are highlighted. This paper is based on the pre-conference symposium "outcome-based curricula: global perspectives" presented by the authors at the 4th Asia Pacific Medical Education Conference (APMEC) in Singapore, 8-11 February, 2007.

    The current study investigated original case descriptions of psychopathy (Cleckley, 1941) in relation to current conceptualizations and general personality traits. Attorneys, forensic psychologists and clinical faculty members completed ratings of psychopathy and personality after reading vignettes based on Cleckley's descriptions of a psychopath. The results suggest that professionals' ratings are consistent with current conceptualizations of psychopathy. Furthermore, the five-factor model (FFM) personality traits of the vignettes aligned with the current literature on the FFM and psychopathy (i.e. low neuroticism, conscientiousness and agreeableness). The results further supported that a general trait model, like the FFM, may be well suited to describe the underlying personality traits of psychopathy. Gender differences were also examined.

    2014-01-01

    A closed-ended intensive pediatric swallowing telepractice program was developed and piloted in one pediatric patient with Opitz BBB/G and Asperger’s Syndromes, oropharyngeal dysphagia and aerophagia. The present study is a case report. Outcome variables included behavioral, swallowing and quality of life variables, and were assessed at baseline and at the end of the four-week program. Selective variables were also assessed at a follow-up family interview four weeks post program completion. Over the four-week intervention period, the patient demonstrated substantial improvements in: oral acceptance of eating-related objects and a variety of foods (behavioral variable), timing of voluntary saliva swallows and aerophagia levels (swallowing variables) and quality of life. Follow-up interview analysis showed that most skills were retained or improved one-month post intervention. This intensive telepractice program proved to be feasible and effective for this pediatric patient with dysphagia. PMID:25945217

  14. Case study on industrial hazmat response teams.

    Stephens, Shelly J

    2009-11-01

    In 1991, Amway formed an industrial hazardous materials (hazmat) team in order to respond quickly and efficiently to potential chemical spills. The company's goals were, and still are today, to protect employees, the environment and the local community, and to reduce the amount of resulting downtime. In 1991, the hazmat team was very well funded, enabling it to become a discrete department with its own management staff and nearly 100 hazmat volunteers. Due to changes in the business climate, Amway reorganised in 2000/01, and the hazmat team became part of a company that incorporated contract work into its scope. When this reorganisation occurred, the hazmat team was thoroughly re-evaluated. Its response function was maintained, but was systematically reinvented in the most lean way practicable while still meeting corporate goals. This case study represents Amway's hazmat team's journey through the evaluation process and subsequent reorganisation. PMID:20378491

    The purpose of this case study was to find out how easy it was to access information on the hygiene standards of eating places open to the public. Using the Freedom of Information (FOI) Act 2000, four adjacent local authorities in South Wales were asked to provide the last food hygiene report of an eating place in their area. The disclosed reports were assessed to determine how useful they would be to an individual seeking more information on a food premise. It was relatively easy to obtain information from two authorities and difficult if not impossible with the others. One local authority refused to release information despite the intervention of the FOI Commissioner. The quality of the information released was variable. This ranged from a completed comprehensive inspection protocol to a hand-written, illegible, incomplete report that failed to adequately differentiate between requirements and recommendations. Without some training in food law and food hygiene it would be difficult to interpret the reports. There was no evidence from the information provided of inspection scoring. The case study raises concerns about the effectiveness of the Act for consumers who wish to obtain information about the hygiene standards of food premises. While the specialist information provided by hygiene inspection reports may be useful to businesses it is not helpful for the lay public. Consumers must be prepared to exercise patience and tenacity if they want this information. Concerns must be raised about the consistency of the inspection process and about the willingness of some local authorities to be transparent about the inspection and enforcement process.

  16. Optimal investment in social signals.

    PubMed

    Dessalles, Jean-Louis

    2014-06-01

    This study is an attempt to determine how much individuals should invest in social communication, depending on the type of relationships they may form. Two simple models of social relationships are considered. In both models, individuals emit costly signals to advertise their "quality" as potential friends. Relationships are asymmetrical or symmetrical. In the asymmetrical condition (first model), we observe that low-quality individuals are discouraged from signaling. In the symmetrical condition (second model), all individuals invest in communication. In both models, high-quality individuals (elite) do not compete and signal uniformly. The level of this uniform signal and the size of the "elite" turn out to be controlled by the accuracy of signals. The two models may be relevant to several aspects of animal and human social communication. PMID:24495174

    2012-01-01

    We study an investment model in which agents have the wrong beliefs about the dynamic properties of fundamentals. Specifically, we assume that agents underestimate the rate of mean reversion. The model exhibits the following six properties: (i) Beliefs are excessively optimistic in good times and excessively pessimistic in bad times. (ii) Asset prices are too volatile. (iii) Excess returns are negatively autocorrelated. (iv) High levels of corporate profits predict negative future excess returns. (v) Real economic activity is excessively volatile; the economy experiences amplified investment cycles. (vi) Corporate profits are positively autocorrelated in the short run and negatively autocorrelated in the medium run. The paper provides an illustrative model of animal spirits, amplified business cycles, and excess volatility. PMID:23243469

    The family is an integral part of one's life. It is very essential that every individual employed or unemployed invests time therein. The family is a source of support and growth for an individual, and the lack of family support or loneliness may be a causative factor in the genesis of psychiatric disorders, especially depression. In India, family plays a paramount role when it comes to mental health of the individual. Tips on how one should invest time in one's family along with the role of a family in one's personal and social structure are discussed. PMID:25838732

  20. Landslide Economics: Concepts and Case Studies

    NASA Astrophysics Data System (ADS)

    Klose, Martin; Damm, Bodo

    2015-04-01

    Landslide economics is vital for fundamental understanding of landslide risk as dealing with two important topics: (i) impact assessment, either as damage statistics or cost modeling, and (ii) vulnerability assessment, i.e., the study of exposure, sensitivity, and resilience to landslide damage, ideally from both sociotechnical and financial perspective (e.g., Crovelli and Coe, 2009; Wills et al., 2014). Many aspects addressed in landslide economics have direct influence on landslide risk, including: (i) human activity is often a major causative factor of landslides, not only by predisposing or triggering them, but also as a result of inadequate (low-cost) landslide mitigation; (ii) the level of tolerable or acceptable risk, a measure driving a large part of landslide costs in industrialized countries, is highly variable, differing between individuals, public or private organizations, and societies, with its nature being to change over time; and (iii) decision makers are faced with finding the right balance in landslide mitigation, thus need to weight diverse geological and socioeconomic factors that control its effectiveness in both technical and financial terms (e.g., Klose et al., 2014a). A large part of the complexity in assessing landslide risk as measured by economic costs is due to unique problems in understanding of (i) what types of landslide damage affect human activity and infrastructure in which way, (ii) how society contributes and responds to various kinds of damage, and (iii) how landslide damage is valued in monetary terms. Landslide economics shows the potential to take account of these sociocultural factors to the benefit of risk analysis (e.g., Klose et al., 2014b). The present contribution introduces local and regional case studies in which different economic issues of landslide risk are highlighted using the example of public infrastructures in NW Germany. A special focus is on the following topics: (i) risk culture and created risk, (ii

    2001-01-01

    Most hemangiopericytomas (HPCs) are located in the musculoskeletal system and the skin, while the intracranial location is rare. They represent 2 to 4% in large series of meningeal tumours, thus accounting for less than 1% of all intracranial tumours. Many authors have argued about the true origin of this tumour. The current World Health Organization classification of Central Nervous System tumours distinguishes HPC as an entity of its own, and classified it into the group of "mesenchymal, non-meningothelial tumours". Radical surgery is the treatment of choice, but must be completed with postoperative radiotherapy, which has proved to be the therapy most strongly related to the final prognosis. HPCs have a relentless tendency for local recurrence and metastases outside the central nervous system which can appear even many years after diagnosis and adequate treatment of the primary tumour. Twelve patients with intracranial HPC were treated at our Unit between 1978 and 1999. There were 10 women and 2 men. Ten tumours were supratentorial and most located at frontoparietal parasagittal level. The most common manner of presentation was a focal motor deficit. All tumours were hyperdense in the basal Computed Tomography scans and most enhanced homogeneously following intravenous contrast injection. In 50% of cases, tumour margins were irregular or lobulated. Seven tumours were studied with Magnetic Resonance Imaging, being six of them iso-intense with the cortical gray matter on T1-weighted and T2-weighted images. Twenty operations were performed in the 12 patients. In 10 cases radical excision could be achieved with no operative mortality. Total recurrence rate was 33.3%. Eight patients were treated with external radiotherapy at some time through the course of their disease. Eight out of the 12 patients in this series are disease-free (Glasgow Outcome Scale categories 1 and 2) after a mean follow up of 52 months. PMID:11534674

  6. Education Fever and the East Asian Fertility Puzzle: A case study of low fertility in South Korea

    PubMed Central

    Anderson, Thomas; Kohler, Hans-Peter

    2014-01-01

    Fertility throughout East Asia has fallen rapidly over the last five decades and is now below the replacement rate of 2.1 in every country in the region. Using South Korea as a case study, we argue that East Asia's ultra-low fertility rates can be partially explained by the steadfast parental drive to have competitive and successful children. Parents throughout the region invest large amounts of time and money to ensure that their children are able to enter prestigious universities and obtain top jobs. Accordingly, childrearing has become so expensive that the average couple cannot afford to have more than just one or two children. The trend of high parental investment in child education, also known as ‘education fever’, exemplifies the notion of ‘quality over quantity’ and is an important contributing factor to understanding low-fertility in East Asia.

    Utz, D.; Jurčák, J.; Bellot-Rubio, L.; del Toro Iniesta, J. C.; Thonhofer, S.; Hanslmeier, A.; Veronig, A.; Muller, R.; Lemmerer, B.

    Due to its magnetic fields our host star - the Sun - becomes the interesting object for research as we know it. The magnetic fields themselves cover different spatial, lifetime and strength scales and reach down from enormous flux concentrations like active sunspot groups to single isolated magnetic flux tubes and even weaker, predominantly inclined intranetwork structures. Flux tubes can be seen in filtergram observations as magnetic bright points (MBPs). They are of interest for research not only due to their sheer existence but due to their important role in atmospheric heating (wave heating as well as reconnection processes), to their role in the understanding of creation and annihilation of magnetic fields as well as to their influence on the total solar irradiance variation. In this study we present a close look onto an evolutionary track of an MBP from its formation to its disintegration. Physical quantities of MBPs like their magnetic field strength and inclination, their line-of-sight velocity, and their temperature at different heights are inferred from the inversion of spectropolarimetric data. Original data are taken from the Sunrise/IMaX instrument and constitute a time series of some 60 min. The presented case resembles the convective collapse model and is in agreement with previous studies.

    1980-01-01

    The authors studied eight sets of healthy twins, ranging in physical maturity from prepubertal to late pubertal, and their parents, to assess psychological changes in early adolescence. A phase-specific psychosocial regression correlates with the biological onset of puberty. We present preliminary findings related to twinship, parental reactions, and longitudinal development, based on detailed case studies. Parents experienced increased conflict, detachment, and pride in response to their twins' psychosocial development at puberty. The more advanced child in a pair tended to lead in all spheres of adjustment-school success, heterosexual interest, peer friendships, and independent behavior. Although the more advanced child began to break away from his twin, in general the twin relationships remained close. Differences in personality traits and rate of psychosocial development within a twinship tended to remain consistent or to become accentuated. They were occasionally narrowed but rarely reversed from early childhood through early adolescence. Some of the differences were fostered by dissimilar patterns of identifying with the parents.

    We present a prospective study of 88 patients with thyroid nodules seen in our institution in 1985-86 and the results of a 5 year follow up. The algorithm for resolution among different therapeutic options was established in regard to the clinical characteristics, imaging and particularly the histopathologic studies. Their age ranged from 18 to 79 years; 94% of the patients were females. Most of the nodules were solid (69%) and measured 1-4 cm in diameter. The image of 62% of the thyroid scans was of a non-functioning nodule and 13% were hyperfunctioning. In 80% the ultrasonographic pattern was solid or mixed. Surgery was undertaken in 19 patients (21%). In 58%, a diagnosis of malignancy was established. The biopsy (aspiration and tru-cut) suggested the presence of the malignant tumors when taken together in 90% of the cases. Hormonal treatment was given to 62 patients; in 40-45% of them there was a significant reduction in the size of the nodule. Aspiration and sclerosis of cystic nodules were performed in 19 patients with significant shrinkage in 82%. Radioactive iodine was used in 11 patients. Our algorithm reduces costs and precludes unnecessary morbidity in patients with thyroid nodules.

    Although astronomy plays an important role in the most various outreach initiatives, as well as school science curricula, due to its strong visual component in knowledge acquisition, astronomy subjects are not entirely well addressed and accessed by visually impaired students and/or general public. This stresses the need of more tactile material production, still very scarce in an educational context whether formal or informal. This is a case study activity developed based on different schematic tactile images of several objects present in our solar system. These images in relief, highlight, through touch, several relevant features present in the different astronomical objects studied. The scientific knowledge is apprehended through the use of a tactile key, complemented with additional information. Through proper hands-on activities implementation and careful analysis of the outcome, the adapted images associated with an explanatory key prove to be a valuable resource in tactile astronomy domain. Here we describe the process of implementing such initiative near visually impaired students. The struggles and challenges perceived by all involved and the enrichment experience of engaging astronomy with visually impaired audiences, broadening horizons in an overall experience accessible to all.

    I will tell you how we transferred a technology from the US Department of Energy`s Pacific Northwest Laboratory to the private sector. I`ll begin by telling about the technology and what it does. Then I`ll tell you how we found a commercial partner to market the technology. And I`ll end by telling you some of the lessons we learned and what our customer thinks about the partnership. This is a success for two reasons. First, the people who developed the technology had faith in its potential. And second, they took an active part in the transfer; they didn`t sit back and wait for someone else to do it. That reminds me of Joe. Night after night, Joe prayed for help in winning the lottery, but his prayers went unanswered. Finally he cried out in desperation: ``Lord, give me a break! Please let me win the lottery!`` Suddenly, lightning flashed across the sky and thunder crashed around him. Then, he heard a voice from above: ``Joe! You give ME a break! BUY A TICKET!`` To succeed in tech transfer, you`ve got to have more than faith. You`ve got to buy a ticket. You`ve got to invest time, energy, imagination, and effort. And that`s just what the developers of the waste acid detoxification and reclamation process did.

  9. Keeping Things Interesting: A Reuse Case Study

    2006-12-01

    Software reuse has several obvious advantages. By taking advantage of the experience and skill of colleagues one not only saves time, money and resources, but can also jump start a project that might otherwise have floundered from the start, or not even have been possible. One of the least talked about advantages of software reuse is it helps keep the work interesting for the developers. Reuse prevents developers from spending time and energy writing software solutions to problems that have already been solved, and frees them to concentrate on solving new problems, developing new components, and doing things that have never been done before. At the National Snow and Ice Data Center we are fortunate our user community has some unique needs that aren't met by mainstream solutions. Consequently we look for reuse opportunities wherever possible so we can focus on the tasks that add value for our user community. This poster offers a case study of one thread through a decade of reuse at NSIDC that has involved eight different development efforts to date.

  10. High Penetration Photovoltaic Case Study Report

    SciTech Connect

    Bank, J.; Mather, B.; Keller, J.; Coddington, M.

    2013-01-01

    Technical concerns with integrating higher penetrations of photovoltaic (PV) systems include grid stability, voltage regulation, power quality (voltage rise, sags, flicker, and frequency fluctuations), and protection and coordination. The current utility grid was designed to accommodate power flows from the central generation source to the transmission system and eventually to the distribution feeders. At the distribution level, the system was designed to carry power from the substation toward the load. Renewable distributed generation, particularly solar PV, provides power at the distribution level challenging this classical paradigm. As these resources become more commonplace the nature of the distribution network and its operation is changing to handle power flow in both directions. This report is focused on large PV installations in which penetration is significantly greater than 15% of maximum daytime feeder load. These case studies are intended to demonstrate success stories with integration of large PV plants at the distribution level as well as some of the solutions used by the utility to ensure safe, reliable operation of both the PV system and the distribution network.

    Ozana, Stepan; Pies, Martin; Docekal, Tomas

    2016-06-01

    Dynamic programming is typically applied to optimization problems. As the analytical solutions are generally very difficult, chosen software tools are used widely. These software packages are often third-party products bound for standard simulation software tools on the market. As typical examples of such tools, TOMLAB and DYNOPT could be effectively applied for solution of problems of dynamic programming. DYNOPT will be presented in this paper due to its licensing policy (free product under GPL) and simplicity of use. DYNOPT is a set of MATLAB functions for determination of optimal control trajectory by given description of the process, the cost to be minimized, subject to equality and inequality constraints, using orthogonal collocation on finite elements method. The actual optimal control problem is solved by complete parameterization both the control and the state profile vector. It is assumed, that the optimized dynamic model may be described by a set of ordinary differential equations (ODEs) or differential-algebraic equations (DAEs). This collection of functions extends the capability of the MATLAB Optimization Tool-box. The paper will introduce use of DYNOPT in the field of dynamic optimization problems by means of case studies regarding chosen laboratory physical educational models.

    To what extent and in what arenas do collaborating musicians need to understand what they are doing in the same way? Two experienced jazz musicians who had never previously played together played three improvisations on a jazz standard ("It Could Happen to You") on either side of a visual barrier. They were then immediately interviewed separately about the performances, their musical intentions, and their judgments of their partner's musical intentions, both from memory and prompted with the audiorecordings of the performances. Statements from both (audiorecorded) interviews as well as statements from an expert listener were extracted and anonymized. Two months later, the performers listened to the recordings and rated the extent to which they endorsed each statement. Performers endorsed statements they themselves had generated more often than statements by their performing partner and the expert listener; their overall level of agreement with each other was greater than chance but moderate to low, with disagreements about the quality of one of the performances and about who was responsible for it. The quality of the performances combined with the disparities in agreement suggest that, at least in this case study, fully shared understanding of what happened is not essential for successful improvisation. The fact that the performers endorsed an expert listener's statements more than their partner's argues against a simple notion that performers' interpretations are always privileged relative to an outsider's.

  13. Environmental injustice: case studies from the South

    NASA Astrophysics Data System (ADS)

    Cifuentes, Enrique; Frumkin, Howard

    2007-10-01

    We selected three case studies to illustrate environmental injustice issues in the South. These examples relate to migrant agricultural workers, the maquiladora industry and artisanal mining, while reviewing some of the major mechanisms involved, e.g. multinational corporations, the development of free trade zones, multilateral free trade agreements and the export of hazards. A series of strategies are discussed in order to address environmental injustice and health disparities that exist on a global scale. Some of the recommendations involve policy initiatives; others, such as research and mentorship, fall within the traditional domain of public health practice. In this paper, special attention is given to concerned environmental and occupational health professionals using evidence-based data for advocacy. For lasting changes to be made, however, stronger institutions and legislation are required. Those who have the 'right to know' about environmental injustice issues include communities of concern, workers' representatives and lawyers. Government officials and company officials may eventually work on the basis of conflict resolution, compensation and remediation, to quote some examples. Systematic approaches to protect both the environment and public health must be updated.

  14. Making Energy-Efficiency and Productivity Investments in Commercial Buildings: Choice of Investment Models

    SciTech Connect

    Jones, D.W.

    2002-05-16

    This study examines the decision to invest in buildings and the types of investment decision rules that may be employed to inform the ''go--no go'' decision. There is a range of decision making tools available to help in investment choices, which range from simple rules of thumb such as payback periods, to life-cycle analysis, to decision theoretic approaches. Payback period analysis tends to point toward lower first costs, whereas life-cycle analysis tends to minimize uncertainties over future events that can affect profitability. We conclude that investment models that integrate uncertainty offer better explanations for the behavior that is observed, i.e., people tend to delay investments in technologies that life-cycle analysis finds cost-effective, and these models also lead to an alternative set of policies targeted at reducing of managing uncertainty.

    1988-01-01

    A case study of the impact of Ada on a Command and Control project completed at the Jet Propulsion Laboratory (JPL) is given. The data for this study was collected as part of a general survey of software costs and productivity at JPL and other NASA sites. The task analyzed is a successful example of the use of rapid prototyping as applied to command and control for the U.S. Air Force and provides the U.S. Air Force Military Airlift Command with the ability to track aircraft, air crews and payloads worldwide. The task consists of a replicated database at several globally distributed sites. The local databases at each site can be updated within seconds after changes are entered at any one site. The system must be able to handle up to 400,000 activities per day. There are currently seven sites, each with a local area network of computers and a variety of user displays; the local area networks are tied together into a single wide area network. Using data obtained for eight modules, totaling approximately 500,000 source lines of code, researchers analyze the differences in productivities between subtasks. Factors considered are percentage of Ada used in coding, years of programmer experience, and the use of Ada tools and modern programming practices. The principle findings are the following. Productivity is very sensitive to programmer experience. The use of Ada software tools and the use of modern programming practices are important; without such use Ada is just a large complex language which can cause productivity to decrease. The impact of Ada on development effort phases is consistent with earlier reports at the project level but not at the module level.

    Pattison, S; Dickenson, D; Parker, M; Heller, T

    1999-01-01

    This paper attempts a partial, critical look at the construction and use of case studies in ethics education. It argues that the authors and users of case studies are often insufficiently aware of the literary nature of these artefacts: this may lead to some confusion between fiction and reality. Issues of the nature of the genre, the fictional, story-constructing aspect of case studies, the nature of authorship, and the purposes and uses of case studies as "texts" are outlined and discussed. The paper concludes with some critical questions that can be applied to the construction and use of case studies in the light of the foregoing analysis. PMID:10070638

    Information and communication systems can improve the timeliness and quality of decisions. These benefits are strategically important to the utility industry in an era of increasing competition. Because these systems often do not reduce labor cost, however, they can be difficult to evaluate. This report presents a new process for reaching consensus of the value of capital investment in information and communication systems. The results of this project is A Strategic Advocacy Process (ASAP), a methodology that can be used to evaluate investments in information technology. ASAP uses belief graphs to produce a living business case showing facts, assumptions, goals, and metrics for measuring progress toward those goals; shows how to use option pricing theory to quantify the value of managerial flexibility; ASAP uses an organizational impact assessment tool to identify the potential impact of new information systems and how to realize the benefits of managerial flexibility. The ASAP methodology addresses the critical problem of correctly valuing information and communication systems. The methodology offers a way to account for the intangible'' value of these systems by recognizing the managerial flexibility these systems can provide in addressing risks and uncovering new business opportunities. Metrics for measuring progress toward new goals can be defined, and plans for achieving the goals can be made. As a result, agreement can be reached on the uses, value, and priority of projects based on a metric other than on labor replacement savings.

    Genome-wide association studies (GWAS) explore the relationship between genome variability and disease susceptibility with either population- or family-based data. Here, we have evaluated the utility of combining population- and family-based statistical association tests and have proposed a method for reducing the burden of multiple testing. Unrelated singleton and parent-offspring trio cases and controls from the Genetics of Kidneys in Diabetes (GoKinD) study were analyzed for genetic association with diabetic nephropathy (DN) in type 1 diabetics (T1D). The Cochran-Armitage test for trend and the family-based association test were employed using either unrelated cases and controls or trios, respectively. In addition to combining single nucleotide polymorphism (SNP) p-values across these tests via Fisher's method, we employed a novel screening approach to rank SNPs based on conditional power for more efficient testing. Using either the population-based or family-based subset alone predictably limited resolution to detect DN SNPs. For 384,197 SNPs passing quality control (QC), none achieved strict genome-wide significance (1.4 × 10(-7)) using 1171 singletons (577/594 cases/controls) or 1738 pooled singletons and offspring probands (841/897). Similarly, none of the 352,004 SNPs passing QC in 567 family trios (264/303 case/control proband trios) reached genome-wide significance. Testing the top 10 SNPs ranked using aggregated conditional power resulted in two SNPs reaching genome-wide significance, rs11645147 on chromosome 16 (p = 1.74 × 10(-4) < 0.05/10 = 0.005) and rs7866522 on chromosome 9 (p = 0.0033). Efficient usage of mixed designs incorporating both unrelated and family-based data may help to uncover associations otherwise difficult to detect in the presence of massive multiple testing corrections. Capitalizing on the strengths of both types while using screening approaches may be useful especially in light of large-scale, next-generation sequencing and rare

  8. Building capacity for evidence informed decision making in public health: a case study of organizational change

    PubMed Central

    2012-01-01

    Background Core competencies for public health in Canada require proficiency in evidence informed decision making (EIDM). However, decision makers often lack access to information, many workers lack knowledge and skills to conduct systematic literature reviews, and public health settings typically lack infrastructure to support EIDM activities. This research was conducted to explore and describe critical factors and dynamics in the early implementation of one public health unit's strategic initiative to develop capacity to make EIDM standard practice. Methods This qualitative case study was conducted in one public health unit in Ontario, Canada between 2008 and 2010. In-depth information was gathered from two sets of semi-structured interviews and focus groups (n = 27) with 70 members of the health unit, and through a review of 137 documents. Thematic analysis was used to code the key informant and document data. Results The critical factors and dynamics for building EIDM capacity at an organizational level included: clear vision and strong leadership, workforce and skills development, ability to access research (library services), fiscal investments, acquisition and development of technological resources, a knowledge management strategy, effective communication, a receptive organizational culture, and a focus on change management. Conclusion With leadership, planning, commitment and substantial investments, a public health department has made significant progress, within the first two years of a 10-year initiative, towards achieving its goal of becoming an evidence informed decision making organization.

    Healthcare organizations have various asset pool funds that can be invested to increase nonoperating revenues. In order to maximize the long-term success of investment efforts, healthcare organizations need to develop comprehensive investment management programs. Such programs identify the assets that can be invested, establish the level of risk each asset type can be exposed to, and match long-term and short-term investment opportunities to the appropriate asset pool. Programs can be managed internally or outsourced to investment management firms with objectives and procedures that are compatible with those of the healthcare organizations' investment policies and guidelines. These policies and guidelines must address asset allocation. Oversight committees must be established to monitor investment performance and reallocate assets, as needed, to take advantage of market movements.

    Investment in women's education possibly has a greater return than investing in areas such as power generation. Education is an economic issue. When the self-fulfilling prophecy of girls' lack of education yielding lower economic worth is compared with the self-fulfilling prophecy of educated women having healthy children and greater earning ability, there is no doubt which scenario is more beneficial to the individual and society. Wages of educated female workers rise by 20%, and personal hygiene and public health improvements contribute to lower fertility and infant mortality. In Pakistan, educating an additional 1000 girls/year would cost $40,000 in 1990 prices. Each year of schooling would reduce the under-5 year child mortality rate by 10%. 1000 women with an extra year of schooling would prevent 60 infant deaths, which if prevented through health care interventions would cost an estimated $48,000. Female fertility would be reduced by about 10% for an extra year of schooling, and thus would avert 660 births or a saving $43,000. Social improvement alone is worth the extra cost. Investing in female education means establishing scholarship funds, providing more free books and other supplies, adapting curricula to cultural and practical concerns, and hiring female teachers. Increasing female primary school enrollment to equal boys enrollment in low income countries would mean educating an extra 25 million girls every/year at a total cost of about $938 million. Equalizing secondary school enrollment would entail educating an extra 21 million girls at a cost of $1.4 billion. The total cost of $2.4 billion constitutes less than .25% of the gross domestic product of low income countries, less than 1% of investment in new capital goods, and less than 10% of defense spending. Investment statistics on power plants in a sample of 57 developing countries showed a return on physical plant assets of less than 4% over the past 3 years and less than 6% over the past 10 years

    2009-01-01

    This case study has used the results of a review of literature to understand the persistence of poor maternal health in Rajasthan, a large state of north India, and to make some conclusions on reasons for the same. The rate of reduction in Rajasthan's maternal mortality ratio (MMR) has been slow, and it has remained at 445 per 1000 livebirths in 2003. The government system provides the bulk of maternal health services. Although the service infrastructure has improved in stages, the availability of maternal health services in rural areas remains poor because of low availability of human resources, especially midwives and clinical specialists, and their non-residence in rural areas. Various national programmes, such as the Family Planning, Child Survival and Safe Motherhood and Reproductive and Child Health (phase 1 and 2), have attempted to improve maternal health; however, they have not made the desired impact either because of an earlier emphasis on ineffective strategies, slow implementation as reflected in the poor use of available resources, or lack of effective ground-level governance, as exemplified by the widespread practice of informally charging users for free services. Thirty-two percent of women delivered in institutions in 2005-2006. A 2006 government scheme to give financial incentives for delivering in government institutions has led to substantial increase in the proportion of institutional deliveries. The availability of safe abortion services is limited, resulting in a large number of informal abortion service providers and unsafe abortions, especially in rural areas. The recent scheme of Janani Suraksha Yojana provides an opportunity to improve maternal and neonatal health, provided the quality issues can be adequately addressed. PMID:19489421

    Background Erythroderma is a rare skin disorder that may be caused by a variety of underlying dermatoses, infections, systemic diseases and drugs. Methods We reviewed the clinical, laboratory and biopsy material of 97 patients diagnosed with erythroderma who were treated in our department over a 6-year period (1996 through 2002). Results The male-female ratio was 1.85:1. The mean age at diagnosis was 46.2 years. The most common causative factors were dermatoses (59.7%), followed by drug reactions (21.6%), malignancies (11.3%) and idiopathic causes (7.2%). Carbamazepine was the most common drug (57.1%). The best clinicopathologic correlation was found in cutaneous T-cell lymphoma and pityriasis rubra pilaris related erythroderma. Apart from scaling and erythema that were present in all patients, pruritus was the most common finding (97.5%), followed by fever (33.6%), lymphadenopathy (21.3%), edema (14.4%) and hyperkeratosis (7.2%). Conclusion This study outlines that underlying etiologic factors of erythroderma may show geographic variations. Our series had a high percentage of erythroderma secondary to preexisting dermatoses and a low percentage of idiopathic cases. There was no HIV-infected patient among our series based on multiple serum antibody tests. The clinical features of erythroderma were identical, irrespective of the etiology. The onset of the disease was usually insidious except in drug-induced erythroderma, where it was acute. The group associated with the best prognosis was that related to drugs. PMID:15882451

  15. Biostratigraphic case studies of six major extinctions

    Sloan, R. E.

    1988-01-01

    Biostratigraphic case studies of six major extinctions show all are gradual save one, which is a catastrophic extinction of terrestrial origin. These extinctions show a continuum of environmental insults from major to minor. The major causes of these extinctions are positive and negative eustatic sea level changes, temperature, or ecological competition. Extraterrestrial causes should not be posited without positive association with a stratigraphically sharp extinction. The Cretaceous-Tertiary terrestrial extinction is considerably smaller in percentage of extinction than the marine extinction and is spread over 10 my of the Cretaceous and 1 my of the Tertiary. Sixty percent of the 30 dinosaurs in the northern Great Plains of the U.S. and Canada had become extinct in the 9 my before the late Maastrichtian sea level drop. The best data on the Permo-Triassic terrestrial extinction are from the Karoo basin of South Africa. This is a series of 6 extinctions in some 8 my, recorded in some 2800 meters of sediment. Precision of dating is enhanced by the high rate of accumulation of these sediments. Few data are readily available on the timing of the marine Permo-Triassic extinction, due to the very restricted number of sequences of Tatarian marine rocks. The terminal Ordovician extinction at 438 my is relatively rapid, taking place over about 0.5 my. The most significant aspect of this extinction is a eustatic sea level lowering associated with a major episode of glaciation. New data on this extinction is the reduction from 61 genera of trilobites in North America to 14, for a 77 percent extinction. Another Ordovician extinction present over 10 percent of the North American craton occurs at 454 my in the form of a catastrophic extinction due to a volcanic eruption which blanketed the U.S. east of the Transcontinental Arch. This is the only other sizeable extinction in the Ordovician.

    Introduction: Mutiple mieloma (MM) cells are rarely found in extramedullary sites. The sites of extramedullary dissemination reported in the literature are spleen, liver, lymph nodes, kidneys, thyroid gland, adrenal gland, ovary, tests, lung, pleura, pericardium, intestinal tract and skin. We report a case in which the myeloma was diagnosed after we discovered the presence of monoclonal plasma cells in the bronchoalveolar lavage fluid (BAL). Matherial and method: a case in which diagnosis was established from bronchoalveolar lavage (BAL) fluid demonstrating the presence of monoclonal plasma cells in Craiova Pneumology Departament. Results: Analysis of BAL fluid for the presence of plasma cells and for cytoplasmic immunoglobulin DNA provides a noninvasive means of establishing the diagnosis. Conclusions: Pulmonary parenchyma is an uncommon site of extramedullary involvement in multiple myeloma. Interstitial lung disease as pulmonary manifestation of multiple myeloma is even rarer; only isolated cases with histological proofs have been reported in the literature. PMID:26788357

    This case study of the Argentina Road Safety Project demonstrates how the application of World Bank road safety project guidelines focused on institution building can accelerate knowledge transfer, scale up investment and improve the focus on results. The case study highlights road safety as a development priority and outlines World Bank initiatives addressing the implementation of the World Report on Road Traffic Injury's recommendations and the subsequent launch of the Decade of Action for Road Safety, from 2011-2020. The case study emphasizes the vital role played by the lead agency in ensuring sustainable road safety improvements and promoting the shift to a 'Safe System' approach, which necessitated the strengthening of all elements of the road safety management system. It summarizes road safety performance and institutional initiatives in Argentina leading up to the preparation and implementation of the project. We describe the project's development objectives, financing arrangements, specific components and investment staging. Finally, we discuss its innovative features and lessons learned, and present a set of supplementary guidelines, both to assist multilateral development banks and their clients with future road safety initiatives, and to encourage better linkages between the health and transportation sectors supporting them.

    This case study of the Argentina Road Safety Project demonstrates how the application of World Bank road safety project guidelines focused on institution building can accelerate knowledge transfer, scale up investment and improve the focus on results. The case study highlights road safety as a development priority and outlines World Bank initiatives addressing the implementation of the World Report on Road Traffic Injury's recommendations and the subsequent launch of the Decade of Action for Road Safety, from 2011-2020. The case study emphasizes the vital role played by the lead agency in ensuring sustainable road safety improvements and promoting the shift to a 'Safe System' approach, which necessitated the strengthening of all elements of the road safety management system. It summarizes road safety performance and institutional initiatives in Argentina leading up to the preparation and implementation of the project. We describe the project's development objectives, financing arrangements, specific components and investment staging. Finally, we discuss its innovative features and lessons learned, and present a set of supplementary guidelines, both to assist multilateral development banks and their clients with future road safety initiatives, and to encourage better linkages between the health and transportation sectors supporting them.

  5. Architecture and power: a family planning clinic as a case study.

    Gillespie, Rosemary

    2002-09-01

    This paper considers the interface between architecture and sociology. In particular, the paper assesses the ways architecture, as a means of ordering space, can have significant implications for cultural practices associated with health and health care. First, the wider context of power relations invested in the built form are considered in a health context, and their impact on social relations explored. Second, the paper draws on a Family Planning Clinic (FPC) as a case study for the exploration of unequal power relations embedded in the materiality and structures of the architectural space in which the service is contained. The paper concludes that rather than a neutral backdrop to social relations, architecture, materiality and space can uphold dominant cultural discourses, social divisions and inequalities.

  6. The Use of Case Studies in Teaching Undergraduate Neuroscience

    Case studies have been the cornerstone of many discoveries in neurology and continue to be an indispensable source of knowledge. Attaching a name, face, and story to the study of neurological disorders makes them more “real” and memorable. This article describes the value of the case study methodology and its advantages as a pedagogical approach. It also illustrates how the seminal case of H.M. can be used to highlight the advantages and disadvantages of the case study methodology. Three exercises are described for incorporating case studies into neuroscience courses. The first exercise requires students to conduct a literature review regarding their assigned case and then design an experiment to address a lingering question regarding that neurological disorder. Survey results of 90 students provide quantitative and qualitative support for this approach. The vast majority of students indicated this exercise was a valuable learning experience; sparked interest in the topic and in biopsychology; increased their knowledge and stimulated critical thinking. The second exercise discusses how students might conduct their own case studies. The third exercise emphasizes the use of case studies as a platform to examine competing hypotheses regarding neurological conditions and their treatment. A table listing case studies appropriate for undergraduate neuroscience courses is included. Cases are categorized by the type of neurological disorder and notes regarding the nature of and content of each case are provided. PMID:23493154

  7. Case studies: Soil mapping using multiple methods

    Soil is a non-renewable resource with fundamental functions like filtering (e.g. water), storing (e.g. carbon), transforming (e.g. nutrients) and buffering (e.g. contamination). Degradation of soils is meanwhile not only to scientists a well known fact, also decision makers in politics have accepted this as a serious problem for several environmental aspects. National and international authorities have already worked out preservation and restoration strategies for soil degradation, though it is still work of active research how to put these strategies into real practice. But common to all strategies the description of soil state and dynamics is required as a base step. This includes collecting information from soils with methods ranging from direct soil sampling to remote applications. In an intermediate scale mobile geophysical methods are applied with the advantage of fast working progress but disadvantage of site specific calibration and interpretation issues. In the framework of the iSOIL project we present here some case studies for soil mapping performed using multiple geophysical methods. We will present examples of combined field measurements with EMI-, GPR-, magnetic and gammaspectrometric techniques carried out with the mobile multi-sensor-system of Kiel University (GER). Depending on soil type and actual environmental conditions, different methods show a different quality of information. With application of diverse methods we want to figure out, which methods or combination of methods will give the most reliable information concerning soil state and properties. To investigate the influence of varying material we performed mapping campaigns on field sites with sandy, loamy and loessy soils. Classification of measured or derived attributes show not only the lateral variability but also gives hints to a variation in the vertical distribution of soil material. For all soils of course soil water content can be a critical factor concerning a succesful

    2010-09-01

    On 31st March 2003 Advanced Tissue Sciences (ATS) was liquidated, with the effect that in excess of US$300 million of stakeholder financing was destroyed. Although successful in the development of breakthrough technologies in the regenerative medicine arena and the building of a substantial portfolio of patents, the company never made a profit. In this case study, ATS’ business strategy, market and competitive environment will be discussed in the context of the company’s historical development. A number of important lessons from this case are discussed. From a management perspective the most critical lesson is the importance of effective financial planning and management of costs, and in particular R&D costs, including the significant costs associated with clinical trials. In addition, a clear strategic focus is extremely important due to the significant resources required in the development of a new therapy. From an investor’s perspective the lessons to be gathered from the ATS case are related to the risk involved in investing in the field of regenerative medicine. This case indicates that both professional and private investors did not fully question the validity of ATS’ business strategy and financial forecasts. A clear and focused strategy based on long-term investor commitment is essential for the successful commercialization of regenerative medicine.

  9. The Cost-Effectiveness of Investments to Meet the Guiding Principles for High-Performance Sustainable Buildings on the PNNL Campus

    2014-08-29

    As part its campus sustainability efforts, Pacific Northwest National Laboratory (PNNL) has invested in eight new and existing buildings to ensure they meet the U.S. Department of Energy’s requirements for high performance sustainable buildings (HPSB) at DOE sites. These investments are expected to benefit PNNL by reducing the total life-cycle cost of facilities, improving energy efficiency and water conservation, and making buildings safer and healthier for the occupants. This study examines the cost-effectiveness of the implementing measures that meet the criteria for HPSBs in 3 different types of buildings on the PNNL campus: offices, scientific laboratories, and data centers. In each of the three case studies examined the investments made to achieve HPSB status demonstrated a high return on the HPSB investments that have taken place in these varied environments. Simple paybacks for total investments in the three case study buildings ranged from just 2 to 5 years; savings-to-investment ratios all exceeded the desirable threshold of 1; and the net present values associated with these investments were all positive.

  15. A case study of preferential bestiality.

    Earls, Christopher M; Lalumière, Martin L

    2009-08-01

    In a previous article, we presented phallometric data to illustrate a case of preferential bestiality or zoophilia (Earls & Lalumière, Sex Abuse: J Res Treat, 14:83-88, 2002). Based on the available literature, we argued that a marked preference for having sex with animals over sex with humans is extremely rare. In the present article, we describe a second case of zoophilia that challenges the widely held assumptions that men who have sex with animals are generally of below average intelligence and come from rural areas. In addition, we provide a brief review of a burgeoning quantitative literature using large groups of zoophiles recruited from internet sources. Although estimates of the prevalence of zoophilia are not possible at this time, it appears that zoophilia is not as rare as once thought and shares many features with other atypical sexual interests.

    2002-09-01

    Seventeen cases of collodion baby are reported. Clinical aspects, complications, treatment, final outcome and family history were studied. We did not observe any clinical features in the collodion baby that could serve as a clue in predicting the final diagnosis. Infections were observed in nine, hypothermia in five and hypernatraemic dehydration in four cases. Skin infection mainly occurred in babies treated with emollients (petrolatum, lanolin and cetomacrogolis cream were used). We therefore recommend treating the collodion baby in a humidified incubator, if necessary with intravenous rehydration, but not to use emollients. The final outcome of these study patients was erythrodermic autosomal recessive lamellar ichthyosis in seven cases (41%), non-erythrodermic autosomal recessive lamellar ichthyosis in three cases (18%), Sjögren-Larsson in one case (6%), epidermolytic hyperkeratosis in one case (6%), acute neonatal variant of Gaucher disease in one case (6%) and normal skin in four cases (24%).

  3. Case studies of thermal energy storage (TES) systems: Evaluation and verification of system performance

    1992-01-01

    We have developed two case studies to review and analyze energy performance of thermal energy storage CMS systems in commercial buildings. Our case studies considered two partial ice storage systems in Northern California. For each case, we compiled historical data on TES design, installation, and operation. This information was further enhanced by data obtained through interviews with the building owners and operators. The performance and historical data of the TES systems and their components were grouped into issues related to design, installation, operation, and maintenance of the systems. Our analysis indicated that (1) almost all problems related to the operation of TES and non-TES systems could be traced back to the design of the system, and (2) the identified problems were not unique to the TES systems. There were as many original problems with conventional'' HVAC systems and components as with TES systems. Judging from the problems related to non-TES components identified in these two case studies, it is reasonable to conclude that conventional systems have as many problems as TES systems, but a failure, in a TES system may have a more dramatic impact on thermal comfort and electricity charges. The objective of the designers of the TES systems in the case-study buildings was to design just-the-right-size systems so that both the initial investment and operating costs would be minimized. Given such criteria, a system is typically designed only for normal and steady-state operating conditions-which often precludes due consideration to factors such as maintenance, growth in the needed capacity, ease of the operation, and modularity of the systems. Therefore, it is not surprising to find that these systems, at least initially, did not perform to the design intent and expectation and that they had to go through extended periods of trouble-shooting.

    Reverse case study is a collaborative, innovative, active learning strategy that nurse educators can use in the classroom. Groups of students develop a case study and a care plan from a list of medications and a short two- to three-sentence scenario. The students apply the nursing process to thoroughly develop a complete case study written as a concept map. The strategy builds on previous learned information and applies the information to new content, thus promoting critical thinking and problem solving. Reverse case study has been used in both associate and baccalaureate nursing degree theory courses to generate discussion and assist students in thinking like a nurse.

    Anejaculation is an uncommon clinical entity that may result from a variety of causes, both organic and psychological. Psychogenic anejaculation is influenced by relationship, behavioral, and psychological factors. We present a clinical case of situational anejaculation, which was managed with a combination of techniques that addressed these factors including changes in masturbatory technique, improved marital communication and quality, and reduction of anxiety using cognitive behavioral techniques. It is suggested that the standard techniques of sex therapy be modified and tailored to manage the specific problems of the individual patient. PMID:25035564

Its pathogenesis remains uncertain. We aim to analyze the epidemiological and clinical profiles of patients with pityriasis amiantacea to better understand treatment responses. We identified seven cases of pityriasis amiantacea and a female predominance in a sample of 63 pediatric patients with seborrheic dermatitis followed for an average of 20.4 months. We reported a mean age of 5.9 years. Five patients were female, with a mean age of 9 years. All patients were successfully treated with topic ketoconazole.

    Humans show a wide array of sexual preferences and behaviors. Although most humans prefer and have sex with consenting adults of the opposite sex, some individuals have unconventional preferences with regard to the sex or age of sexual partners, or with regard to the nature of sexual activities. In this paper, we describe a rare case of preferential bestiality, or zoophilia. The client meets the most stringent criteria for the diagnosis of zoophilia. In particular, his phallometrically measured arousal pattern shows a sexual preference for horses over other species, including humans.

    The painful os trigonum syndrome is one cause of posterolateral ankle pain. This syndrome is most prevalent in athletes who perform frequent and/or forceful plantar flexion. The painful os trigonum may be misdiagnosed as Achilles and/or peroneal tendinitis. In this case, the patient was misdiagnosed for 15 months and treated for tendinitis. The appropriate clinical tests to evaluate the os trigonum as a source of posterolateral ankle pain are outlined. The surgical and postoperative management for the patient are discussed. Clinicians should be aware of the painful os trigonum syndrome as a possible source of posterolateral ankle pain.

    Drawing on the evolutionary terminal investment hypothesis and Trivers' (1974) parent-offspring conflict theory, we advance and evaluate a mediational model specifying why and how maternal age, via mating effort and parental investment, affects mother-child conflict. Data from a longitudinal study of 757 families indicate that (a) older maternal age predicts lower mating effort during the child's first 5 years of life, and (b) thereby, higher maternal investment in middle childhood when the child is around 10 years old. (c) Higher maternal investment, in turn, forecasts less child-perceived mother-child conflict in adolescence (age 15). These results proved robust against theoretically relevant covariates (family resources, parity, maternal education, and maternal personality characteristics) and in the context of an autoregressive model. Study limitations are noted and results are discussed in terms of the unique contributions of an evolutionary perspective to the determinants-of-parenting literature.

    Case-Control study design is a type of observational study. In this design, participants are selected for the study based on their outcome status. Thus, some participants have the outcome of interest (referred to as cases), whereas others do not have the outcome of interest (referred to as controls). The investigator then assesses the exposure in both these groups. The investigator should define the cases as specifically as possible. Sometimes, definition of a disease may be based on multiple criteria; thus, all these points should be explicitly stated in case definition. An important aspect of selecting a control is that they should be from the same ‘study base’ as that of the cases. We can select controls from a variety of groups. Some of them are: General population; relatives or friends; and hospital patients. Matching is often used in case-control control studies to ensure that the cases and controls are similar in certain characteristics, and it is a useful technique to increase the efficiency of the study. Case-Control studies can usually be conducted relatively faster and are inexpensive – particularly when compared with cohort studies (prospective). It is useful to study rare outcomes and outcomes with long latent periods. This design is not very useful to study rare exposures. Furthermore, they may also be prone to certain biases – selection bias and recall bias. PMID:27057012

  19. Applying Real Options for Evaluating Investments in ERP Systems

    NASA Astrophysics Data System (ADS)

    Nakagane, Jun; Sekozawa, Teruji

    This paper intends to verify effectiveness of real options approach for evaluating investments in Enterprise Resource Planning systems (ERP) and proves how important it is to disclose shadow options potentially embedded in ERP investment. The net present value (NPV) method is principally adopted to evaluate the value of ERP. However, the NPV method assumes no uncertainties exist in the object. It doesn't satisfy the current business circumstances which are filled with dynamic issues. Since the 1990s the effectiveness of option pricing models for Information System (IS) investment to solve issues in the NPV method has been discussed in the IS literature. This paper presents 3 business cases to review the practical advantages of such techniques for IS investments, especially ERP investments. The first case is EDI development. We evaluate the project by a new approach with lighting one of shadow options, EDI implementation. In the second case we reveal an ERP investment has an “expanding option” in a case of eliminating redundancy. The third case describes an option to contract which is deliberately slotted in ERP development to prepare transferring a manufacturing facility.

    2013-01-01

    Summary Background Significant controversy exists in the literature regarding the role of pregnancy in the prognosis of breast cancer. We designed a matched case-case study, matching pregnancy-associated breast cancer (PABC) cases with breast cancer cases for stage, age, and year of diagnosis. Patients and Methods 39 consecutive cases of PABC were matched with 39 premenopausal cases of breast cancer. Univariate and multivariate survival analyses followed by adjustment for stage, grade, estrogen receptor status, and age at diagnosis, were performed. Results Regarding overall survival (OS), univariate analysis pointed to longer OS in non-PABC cases vs. PABC cases. Accordingly, a more advanced stage predicted shorter survival. In the multivariate analysis, the independent aggravating effect mediated by pregnancy persisted. Interestingly, a post hoc nested analysis within PABC cases indicated that the 3rd trimester pointed to shorter OS. The aforementioned results on OS were also replicated during the examination of relapse-free survival. Conclusion Implementing a matched case-case design, the present study points to pregnancy as a poor prognostic factor for breast cancer. PMID:24415971
