  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?

    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

    Curtin, Kathleen; Beckman, Howard; Pankow, George; Milillo, Yuliya; Green, Robert A

    2006-01-01

    With purchasers' increasing frustration with healthcare costs, more innovative approaches to performance-based reimbursement are in demand. Establishing pay-for-performance programs has become a popular strategy for reorienting payments from rewarding volume to rewarding adherence to performance measures. However, while performance on quality measures has improved, no reports exist about the return on investment (ROI) of pay-for-performance programs. This article compares the overall costs of implementing and maintaining a pay-for-performance program with the resulting cost trend savings for diabetes care for a health maintenance organization's (HMO's) population. The program was a five-year partnership (2000-2004) between a health plan and an independent practice association (IPA) for the HMO product. It reported performance scores on quality, patient satisfaction, and practitioner efficiency at the individual physician level. Physician performance reporting began in 1999, and payment for that performance began in 2002. The cost of the program was 1,150,000 dollars yearly. Savings for diabetes alone in 2003, the first post-intervention year, were 1,894,471dollars. Second-year (2004) savings against the two-year rolling trend were 2,923,761 dollars. For 2003, the resulting ROI was 1.6:1, and for 2004, it was 2.5:1. To our knowledge, this article is the first report of a positive ROI for an HMO-based pay-for-performance program, and it begins to answer the question of whether the investment in such programs is worth the effort.

    2002-09-01

    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.

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

    SciTech Connect

    Tom, B.M.

    1988-01-01

    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.

    It has been suggested that initiatives to eradicate specific communicable diseases need to be informed by eradication investment cases to assess the feasibility, costs, and consequences of eradication compared with elimination or control. 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.

    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.

  6. Biological dimensions of tern management-a case study of the least tern in Sonora, Mexico, and a comparative analysis of reproductive investment in terns

    USGS Publications Warehouse

    Rosemartin, Alyssa; van Riper, Charles, III

    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.

    2014-01-01

    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. PMID:25147845

  13. Multilateral development banks and socially responsible investments--the case of tobacco.

    PubMed

    Lal, Pranay

    2012-12-01

    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 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.

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

    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.

    In the aftermath of the Ebola crisis, the global health community has a unique opportunity to reflect on the lessons learned and apply them to prepare the world for the next crisis. 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.

    Global prevention and control of infectious diseases requires significant investment of financial and human resources and well-functioning leadership and management structures. The reality of competing demands for limited resources leads to trade-offs and questions about the relative value of specific investments. Developing investment cases can help to provide stakeholders with information about the benefits, costs, and risks associated with available options, including examination of social, political, governance, and ethical issues. We describe the process of developing investment cases for globally coordinated management of action plans for measles and rubella as tools for enabling the implementation of the Global Vaccine Action Plan (GVAP). We focus on considerations related to the timing of efforts to achieve measles and rubella goals independently and within the context of ongoing polio eradication efforts, other immunization priorities, and other efforts to control communicable diseases or child survival initiatives. Our analysis suggests that the interactions between the availability and sustainability of financial support, sufficient supplies of vaccines, capacity of vaccine delivery systems, and commitments at all levels will impact the feasibility and timing of achieving national, regional, and global goals. The timing of investments and achievements will determine the net financial and health benefits obtained. The methodology, framing, and assumptions used to characterize net benefits and uncertainties in the investment cases will impact estimates and perceptions about the value of prevention achieved overall by the GVAP. We suggest that appropriately valuing the benefits of investments of measles and rubella prevention will require the use of integrated dynamic disease, economic, risk, and decision analytic models in combination with consideration of qualitative factors, and that synthesizing information in the form of investment cases may help

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

    NASA Astrophysics Data System (ADS)

    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.

    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.

  15. Potential Opportunities for Investment in Space Technologies in Latin-America: a Case for Mexico

    NASA Astrophysics Data System (ADS)

    Sanchez, G.

    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

    PubMed Central

    2013-01-01

    Background Without addressing the constraints specific to disadvantaged populations, national health policies such as universal health coverage risk increasing equity gaps. Health system constraints often have the greatest impact on disadvantaged populations, resulting in poor access to quality health services among vulnerable groups. Methods The Investment Cases in Indonesia, Nepal, Philippines, and the state of Orissa in India were implemented to support evidence-based sub-national planning and budgeting for equitable scale-up of quality MNCH services. The Investment Case framework combines the basic setup of strategic problem solving with a decision-support model. The analysis and identification of strategies to scale-up priority MNCH interventions is conducted by in-country planners and policymakers with facilitation from local and international research partners. Results Significant variation in scaling-up constraints, strategies, and associated costs were identified between countries and across urban and rural typologies. Community-based strategies have been considered for rural populations served predominantly by public providers, but this analysis suggests that the scaling-up of maternal, newborn, and child health services requires health system interventions focused on 'getting the basics right'. These include upgrading or building facilities, training and redistribution of staff, better supervision, and strengthening the procurement of essential commodities. Some of these strategies involve substantial early capital expenditure in remote and sparsely populated districts. These supply-side strategies are not only the 'best buys', but also the 'required buys' to ensure the quality of health services as coverage increases. By contrast, such public supply strategies may not be the 'best buys' in densely populated urbanised settings, served by a mix of public and private providers. Instead, robust regulatory and supervisory mechanisms are required to improve

    To understand the involvement of the State of Indiana with the Center for Applied Optics at Rose-Hulman Institute of Technology, it is best to start with an explanation of the Indiana Corporation for Science and Technology (CST), its basic charter and its programs. Established in 1982 as a private not-for-profit corporation, CST was formed to promote economic development within the State of Indiana. Two programs that were initially a part of CST's charter and supported with state dollars were a seed capital investment program, aimed at developing new products and processes, and the establishment of university centers of technology development. The former was conceived to create jobs and new, technologically advanced industries in Indiana. The latter was an attempt to encourage technology transfer from the research laboratories of the state universities to the production lines of Indiana industry. Recently, CST has undergone a name change to the Indiana Business Modernization and Technology Corporation (BMT) and adopted an added responsibility of proactive assistance to small- and medium-sized businesses in order to enhance the state's industrial competitiveness.

    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

  3. Study of resin-bonded calcia investment: Part 1. Setting time and compressive strength.

    Nakai, A

    2000-09-01

    This study was carried out to develop a new titanium casting investment consisting of calcia as the refractory material and a cold-curing resin system as the binder. The setting time of the investment was investigated under different N,N-dimethyl-p-toluidine (DMPT) contents in methyl methacrylate monomer (MMA) and benzoyl peroxide (BPO) contents in calcia without any sintering agent. The effects of the sintering agents, which were calcium fluoride (CaF2) and calcium chloride (CaCl2), on the compressive strength of the investments were investigated at room temperature before and after heating to two different temperatures. The shortest setting time (68 minutes) of the investment was obtained at 0.37 DMPT/BPO (1.5 vol% /1.0 mass%) ratio by mass. The highest strength (16.5 MPa) was obtained from the investment which contained 2 mass% CaF2 and was heated to 1,100 degrees C. It was found that the developed calcia investment containing 2 mass% CaF2 has a possibility for use in titanium castings. PMID:11218848

    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

    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

    This study extensively investigated the outflow of FDI from the Middle East (ME), its reasons, its characteristics, its form of ownership, and how it relates and compares with other MNCs in general and TWCs in particular. The comparison primarily focused on: (1) motives for investing abroad, and (2) the criteria used for selecting host countries. The research revealed that ME MNCs, generally, shared many views regarding their motivations and criteria. However, some differences were found to exist between Egyptian firms, on one hand, and Kuwaiti and Saudi firms, on the other hand. These differences were primarily attributed to the differences in the nature of the ownership advantages possessed by each group. The primary advantage of the Kuwaiti and Saudi firms was their capital-surplus positions. The primary advantage of the Egyptian firms was their managerial and marketing skills. ME MNCs were also found to have some similarities, regarding their FDI motivations and criteria, with other TW MNCs. Yet, there were some sharp differences. Again, the nature of the ownership advantages, and the business types, were found to explain these differences.

    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

    Objective To investigate the effect of targeted marginal annual investments by local healthcare commissioners on the outcomes they expected to achieve with these investments. Design Controlled before and after study. Setting: 152 commissioning organisations (primary care trusts) in England. Methods National surveys of commissioning managers in 2009 and 2010 to identify: the largest marginal investments made in four key conditions/services (diabetes, coronary heart disease, chronic pulmonary airways disease and emergency and urgent care) in 2008/2009 and 2009/2010; the outcomes commissioners expected to achieve with these investments; and the processes commissioners used to develop these investments. Collation of routinely available data on outcomes commissioners expected from these investments over the period 2007/2008 to 2010/2011. Results 51% (77/152) of commissioners agreed to participate in the survey in 2009 and 60% (91/152) in 2010. Around half reported targeted marginal investments in each condition/service each year. Routine data on many of the outcomes they expected to achieve through these investments were not available. Also, commissioners expected some outcomes to be achieved beyond the time scale of our study. Therefore, only a limited number of outcomes of investments were tested. Outcomes included directly standardised emergency admission rates for the four conditions/services, and the percentage of patients with diabetes with glycated haemoglobin <7. There was no evidence that targeted marginal investments reduced emergency admission rates. There was evidence of an improvement in blood glucose management for diabetes for commissioners investing to improve diabetes care but this was compromised by a change in how the outcome was measured in different years. This investment was unlikely to be cost-effective. Conclusions Commissioners made marginal investments in specific health conditions and services with the aim of improving a wide range of outcomes

    This study estimates that Medicare extra payments under the hospital prospective payment system (PPS) range from about $700 per case of decubitus ulcer to $9,000 per case of postoperative sepsis in the five types of adverse events identifiable in Medicare claims. Medicare extra payment for the five types of events totals more than $300 million per year, accounting for 0.27 percent of annual Medicare hospital spending. But these extra payments cover less than a third of the extra costs incurred by hospitals in treating these adverse events. We conclude that both Medicare and hospitals gain financially by improving patient safety. PMID:16966737

  8. 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

  10. 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

  11. Vertebral Angiosarcoma. Case Study.

    2015-01-01

    Bone angiosarcomas, especially vertebral angiosarcomas, are very rare. There are no studies based on large clinical samples in the literature, and only a few single case reports can be found. The symptoms of the disease are not specific. It is usually detected incidentally or at a late stage when pathological vertebral fractures or neurological complications occur. Diagnostic imaging and history help to recognize the tumour behind the symptoms, but do not allow accurate clinical diagnosis. The basis for a diagnosis is the histopathological examination supported by immunohistochemistry (IHC) assays. The case of a 26-year-old woman with an angiosarcoma involving the eighth thoracic vertebra we report reflects diagnostic problems adversely affecting the efficacy and accuracy of treatment offered to patients. The patient underwent three surgeries of the spine, including two biopsies. A needle biopsy did not provide sufficient information for the diagnosis. An open excisional biopsy, which at the same time temporarily reduced neurological deficits in the patient, was the only chance to obtain an accurate diagnosis. The third surgery was posterior decompression of the spinal cord due to the rapidly escalating paraparesis. It was not until 8 weeks later that the final diagnosis was established. At that time, the patient could not be qualified for any supplementary treatment. The patient died in hospital 6 months after the onset of disease. PMID:26468177

    Delphi Automotive Systems and the Los Alamos National Laboratory worked together to develop PREDICT, a new methodology to characterize the reliability of a new product during its development program. Rather than conducting testing after hardware has been built, and developing statistical confidence bands around the results, this updating approach starts with an early reliability estimate characterized by large uncertainty, and then proceeds to reduce the uncertainty by folding in fresh information in a Bayesian framework. A considerable amount of knowledge is available at the beginning of a program in the form of expert judgment which helps to provide the initial estimate. This estimate is then continually updated as substantial and varied information becomes available during the course of the development program. This paper presents a case study of the application of PREDICT, with the objective of further describing the methodology. PREDICT has been honored with an R&D 100 Award presented by R&D Magazine.

  13. 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.

    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

    Caring for J.D. was a stressful experience. The extent of her wounds, pain, and limited options for treatment was very frustrating for the nursing staff. Although she did not survive, patient outcomes were met to some degree. Her pain was controlled to a greater extent, and there was less infection present in her wounds. The nurses worked with J.D. closely to improve her pain control and facilitate less painful dressing changes. They were vigilant in assessing the progress of her wound healing and communicating any increased signs of infections from her wounds. They sang with her to help distract her from the pain she was experiencing and to help her cope with her lengthy 8-month hospitalization. Providing care for J.D. was also a very important learning experience for nurses in terms of appropriate pain management for patients with CUA, wound care, and the need to sustain adequate nutrition to promote wound healing. CUA is a rare but potentially fatal disease that occurs in patients with end stage renal disease (ESRD). Early diagnosis and treatment are essential to prevent the devastating effects of this disease. Nephrology nurses need to reinforce the importance of keeping calcium, phosphorous, and parathyroid levels within normal ranges for their patients on dialysis. They also need to be vigilant in monitoring for potential CUA skin lesions to prevent and treat it early. To date, treatment options are mostly based on findings from case reports. Treatment requires a multidisciplinary approach with input from nephrologists, nurses, pain specialists, infectious disease specialists, and surgeons. The major goals of treatment are controlling risk factors, controlling pain, and preventing wound infection and possible sepsis. More studies need to be conducted to test interventions that may help treat CUA. PMID:23094342

    Syncope, or the sudden loss of consciousness, is a common presenting symptom for evaluation by neurologists. It is not a unique diagnosis but rather a common manifestation of disorders with diverse mechanisms. Loss of consciousness is typically preceded by a prodrome of symptoms and sometimes there is a clear trigger. This article discusses several cases that illustrate the various causes of syncope. Reflex syncope is the most common type and includes neurally mediated, vasovagal, situational, carotid sinus hypersensitivity, and atypical forms. Acute and chronic autonomic neuropathies and neurodegenerative disorders can also present with syncope. PMID:27445240

    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.

    Studies were performed on a number of operating cogeneration systems to determine application, economics, and attitudes of industrial and utility executives toward cogeneration. A literature survey was conducted and an identification of candidate cogeneration sites was carried out. This was followed by a screening of these sites down to 20 to 30 candidate sites. The screening was carried out on the basis of cogeneration capacity, geographical diversity, generation type, and industrial diversity. The remaining sites were contacted as to their willingness to work with EPRI, and an industrial questionnaire was developed on technical, economic, and institutional cogeneration issues. Each of the seventeen sites was visited during this task. A utility questionnaire was developed and utilities with cogeneration systems studied in this survey were contacted as to their attitudes toward cogeneration. In addition, a compilation of a list of operating cogeneration systems was performed.

    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.

    Insight is provided toward the development of an optimal program for investment analysis of project proposals offering commercial potential and its components. This involves a critique of economic investment criteria viewed in relation to requirements of engineering economy analysis. An outline for a systems approach to project analysis is given Application of the Leontief input-output methodology to analysis of projects involving multiple processes and products is investigated. Effective application of elements of neoclassical economic theory to investment analysis of project components is demonstrated. Patterns of both static and dynamic activity levels are incorporated.

  15. Investment Evaluation of RFID TechnologyApplications: An Evolution Perspective

    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.

    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.

    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. PMID:25869304

    Objectives To test the hypothesis that certain individual, environmental and lifestyle factors are positively associated with beneficial health investment behaviours and oral/periodontal health among adolescents. Methods Five hundred and six randomly selected 19-year old subjects living in two different areas (Fyrbodal and Skaraborg) in the county council of Västra Götaland, Sweden participated in a clinical examination and answered questionnaires covering psycho-social and health behavioural issues. Two oral-health models were estimated with gingivitis score as an objective and self-perceived oral health as a subjective indicator. Three health- investment behaviour models were designed with indicators directly related to oral health and two with indicators related to general health as well. The explanatory variables included gender, upper secondary education programme, native country, living area, general self-efficacy and parents' education level. Results In the objective oral-health model, theoretical studies and living in the Skaraborg area were both positively associated with a lower gingivitis score. For the subjective oral-health indicator, none of the explanatory variables showed statistical significance. In the investment-behaviour model with 'tooth-brushing ≥ 2 times daily' as a health indicator, female gender and theoretical studies showed statistically significant associations. With the indicators 'no/few missed dental appointments', 'no tobacco use' and 'weekly exercise', theoretical studies were statistically significant and positively associated. In the investment model with 'perceived oral health care attention' as an indicator, a high score of general self-efficacy was significantly associated with the feeling of taking good care of the teeth. Conclusions Individual, environmental and lifestyle factors are associated with young individuals' oral health investment behaviours and gingival health conditions. PMID:26599291

    A nationwide micro-econometric model was established to estimate changes in the national gross product based on road-related investment amounts. And by considering the supply-demand balance during inflationary and deflationary times and the price adjustment mechanism, this model was then used to examine issues with the current micro-econometric model in light of the present economic circumstances. The results showed that during deflationary times issuing government bonds is less likely to have a crowding-out effect and public investments tend to be more effective than during inflationary times.

    Individuals of different quality may have different investment strategies, shaping responses to experimental manipulations, thereby rendering the detection of such patterns difficult. However, previous clutch-size manipulation studies have infrequently incorporated individual differences in quality. To examine costs of incubation and reproductive investment in relation to changes in clutch size, we enlarged and reduced natural clutch sizes of four and five eggs by one egg early in the incubation period in female common eiders (Somateria mollissima), a sea duck with an anorectic incubation period. Females that had produced four eggs (lower quality) responded to clutch reductions by deserting the nest more frequently but did not increase incubation effort in response to clutch enlargement, at the cost of reduced hatch success of eggs. Among birds with an original clutch size of five (higher quality), reducing and enlarging clutch size reduced and increased relative body mass loss respectively without affecting hatch success. In common eiders many females abandon their own ducklings to the care of other females. Enlarging five-egg clutches led to increased brood care rate despite the higher effort spent incubating these clutches, indicating that the higher fitness value of a large brood is increasing adult brood investment. This study shows that the ability to respond to clutch-size manipulations depends on original clutch size, reflecting differences in female quality. Females of low quality were reluctant to increase investment at the cost of lower hatch success, whereas females of higher quality apparently have a larger capacity both to increase incubation effort and brood care investment.

    Objective Periodontal infections have been linked to cardiovascular disease, including atherosclerosis, and systemic inflammation has been proposed as a possible mediator. Secretory phospholipase A2 (s-PLA2) and Lipoprotein-associated PLA2 (Lp-PLA2) are inflammatory enzymes associated with athero-sclerosis. No data are available on the association between oral microbiota and PLA2s. We studied whether a relationship exists between periodontal microbiota and the activities of these enzymes. Methods The Oral Infection and Vascular Disease Epidemiology Study (INVEST) collected subgingival biofilms and serum samples from 593 dentate men and women (age 68.7 ± 8.6 years). 4561 biofilm samples were collected in the two most posterior teeth of each quadrant (average 7/participant) for quantitative assessment of 11 bacterial species using DNA–DNA checkerboard hybridization. Mean concentration of s-PLA2 and activities of s-PLA2 and Lp-PLA2 were regressed on tertiles of etiologic dominance (ED). ED is defined as the level of presumed periodontopathic species/combined level of all eleven species measured, and represents the relative abundance of periodontopathic organisms. Analyses were adjusted for age, sex, race/ethnicity, education, smoking, BMI, diabetes, LDL cholesterol and HDL cholesterol, and systolic blood pressure. Results Higher levels of s-PLA2 activity were observed across increasing tertiles of etiologic dominance (0.66 ± 0.04 nmol ml−1 min−1, 0.73 ± 0.04 nmol ml−1 min−1, 0.89 ± 0.04 nmol ml−1 min−1; p < 0.001), with also a trend of association between Lp-PLA2 activity and ED (p = 0.07), while s-PLA2 concentration was unrelated to ED. Conclusion Increasingly greater s-PLA2 activity at higher tertiles of etiologic dominance may provide a mechanistic explanatory link of the relationship between periodontal microbiota and vascular diseases. Additional studies investigating the role of s-PLA2 are needed. PMID:26282947

  8. 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.

    1979-01-01

    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

  10. A case for case studies: exploring the use of case study design in community nursing research.

    PubMed

    Bergen, A; While, A

    2000-04-01

    The case study has become an accepted vehicle for conducting research in a variety of disciplines. However, the meaning behind the term is not always made explicit by researchers and this has given rise to a number of assumptions which are open to challenge, and to questions about the robustness of the method. This paper explores some of the issues arising from one particular definition of case study research, used in a study by Yin which examined the practice of case management in community nursing. Four main areas are discussed. First, defining 'case' is seen to pose questions about the relationship of the phenomenon to its context, the degree of researcher control over case definition, the limits to what may constitute a 'case' and what is meant by the term 'unit of analysis'. Second, the relevance of external validity to case study research is supported through the use of a number of tactics, in particular Yin's concept of replication logic, which involves generalizing to theory, rather than to empirical data. Third, the use of method triangulation (multiple methods of data collection) is advanced as a means of enhancing construct validity in research where data converge around a particular theory. Finally, the relationship of the case study to theory construction, through the prior development of 'propositions' is discussed. Each of these issues is applied to the design and conduct of a research study based closely on Yin's multiple case study framework. Thirteen 'cases' were selected of case management practice and data were collected through interviews and examination of literature and documentation, to explore the suitability of community nurses for the role. It is concluded that, given the appropriate subject matter, context and research aims, the case study method may be seen as a credible option in nursing research. PMID:10759989

  11. Dynamic flood risk: case studies

    Di Baldassarre, Giuliano

    2013-04-01

    While many progresses have been made in the static assessment of (current) flood risk, additional transdisciplinary research is required for the development of new methods for the dynamic assessment of (future) flood risk, which is very much needed in a rapidly changing environment. To this end, it is essential to understand why flood risk has changed in the past. This presentation shows the scientific outcomes of diverse case studies (the Po river in Italy and a number of African rivers), whereby data and models are utilized to analyse and interpret the dynamics of flood risk. In particular, a number of hypotheses were tested by considering different agents of change, such as climate and/or land-use, flood prevention measures, human population dynamics. These case studies show that one of the main challenges in assessing (dynamic) flood risk is the deep interconnection not only between the different agents of change, but also between the components of risk (i.e. hazard, exposure, vulnerability or resilience). For instance, changes in flood hazard often trigger changes in exposure and vulnerability to flooding, and vice versa. These complex interactions seem to make predictions of future flood risk over long time scales rather difficult, if not impossible.

    Analysts need to keep track of their analytic findings, observations, ideas, and hypotheses throughout the analysis process. While some visual analytics tools support such note-taking needs, these notes are often represented as objects separate from the data and in a workspace separate from the data visualizations. Representing notes the same way as the data and integrating them with data visualizations can enable analysts to build a more cohesive picture of the analytical process. We created a note-taking functionality called CZNotes within the visual analytics tool CZSaw for analyzing unstructured text documents. CZNotes are designed to use the same model as the data and can thus be visualized in CZSaw's existing data views. We conducted a preliminary case study to observe the use of CZNotes and observed that CZNotes has the potential to support progressive analysis, to act as a shortcut to the data, and supports creation of new data relationships.

    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.

    Many microparasites infect new hosts with specialized life stages, requiring a subset of the parasite population to forgo proliferation and develop into transmission forms. Transmission stage production influences infectivity, host exploitation, and the impact of medical interventions like drug treatment. Predicting how parasites will respond to public health efforts on both epidemiological and evolutionary timescales requires understanding transmission strategies. These strategies can rarely be observed directly and must typically be inferred from infection dynamics. Using malaria as a case study, we test previously described methods for inferring transmission stage investment against simulated data generated with a model of within-host infection dynamics, where the true transmission investment is known. We show that existing methods are inadequate and potentially very misleading. The key difficulty lies in separating transmission stages produced by different generations of parasites. We develop a new approach that performs much better on simulated data. Applying this approach to real data from mice infected with a single Plasmodium chabaudi strain, we estimate that transmission investment varies from zero to 20%, with evidence for variable investment over time in some hosts, but not others. These patterns suggest that, even in experimental infections where host genetics and other environmental factors are controlled, parasites may exhibit remarkably different patterns of transmission investment.

  20. Allographic agraphia: A case study

    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.

  5. 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.

    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.

  8. 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.

  11. The Economics of an Investment in Kaizen

    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.

  18. 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

  2. A case study of embarrassment.

    PubMed

    Dann, O T

    1977-01-01

    The psychoanalytic references to embarrassment are reviewed. Embarrassment, in the literature, is seen largely as an affect involving exhibitionistic and scopophilic conflicts and defenses against these. A case in which embarrassment was prominent is discussed. Embarrassment in the patient was an ego response which implied an external object for its manifestation. It involved exhibitionistic and scopophilic conflicts and projective defenses, but also operated in ego-gratifying and adaptive ways. Her embarrassment was understood through the analysis of an initial embarrassing dream of nakedness and other dreams and associated material as the defensive out-grouth of repeated exposures to the primal scene. Embarrassment was a resistance to remembering in the analysis, and the primal-scene experiences were partially reconstructed. The analytic situation was, in many ways, a symbolic re-creation of the primal scene, including the patient's response of embarrassment. The development of embarrassment in the patient's childhood was furthered and confirmed by its being an identification with the attitudes of both parents. Finally, some reflections on embarrassment and shame in its various forms are set forth. PMID:560404

  3. Modern midwifery: two case studies.

    PubMed

    Anderson, S

    1985-01-01

    To gain more understanding of the practices of modern midwives, 2 births occurring in a Botswanan District Hospital Maternity Ward were observed by a research assistant. Naturalistic observation was considered more reliable than interviews with either patients or modern midwives to assess the biosocial aspects of birth in the modern sector. At admission to the labor room, these 2 midwives checked the patient's blood pressure, performed a vaginal examination, checked the fetal heart, palpated the uterus, shaved the public hair, and administered an enema. Both midwives did not communicate with their patients during these procedures or offer information on the results. The patients were told not to push; 1 midwife commented, "In the hospital, nobody delivers by herself." Rather, patients were instructed to do their "breathing exercises," a term with which they were not familiar and was not explained. In the 1st case, an episiotomy was performed. Both births were uneventful in terms of complications, but marked by a lack of attention to the psychological needs of the patient or sufficient explanations as to the progress of the delivery. Overall, all communications between the modern midwives observed and their patients were impersonal, with an emphasis on technical procedures. PMID:12282440

    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.

    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

    Rajadhyaksha, Viraj

    2010-07-01

    Conducting clinical trial feasibility is one of the first steps in clinical trial conduct. This process includes assessing internal and environmental capacity, alignment of the clinical trial in terms of study design, dose of investigational product, comparator, patient type, with the local environment and assessing potential of conducting clinical trial in a specific country. A robust feasibility also ensures a realistic assessment and capability to conduct the clinical trial. For local affiliates of pharmaceutical organizations, and contract research organizations, this is a precursor to study placement and influences the decision of study placement. This article provides details on different types of feasibilities, information which is to be included and relevance of each. The article also aims to provide practical hands-on suggestions to make feasibilities more realistic and informative. PMID:21814631

    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.

    2012-09-01

    Labyrinthine sequestrum, a rare form of labyrinthitis, is highly distinct from the more commonly encountered labyrinthitis ossificans based on its unique clinical, radiologic, and histologic characteristics. The study included 4 such patients who had undergone clinical and laboratory investigations, computed tomography (CT), and magnetic resonance imaging (MRI) assessments followed by surgical procedures and pathological evaluation. Their major symptoms were otorrhea, otalgia, tinnitus, and profound hearing loss. Imaging studies showed an osteolytic soft mass with calcified debris in the inner ear, and the bony labyrinth was eroded partly or completely by granulation mass, with loss of bony morphology. Further pathological examination was coincident with inflammatory granulation tissue with some calcification or osseous tissue. The disease process is attributed to chronic osteomyelitis due to the presence of osteonecrosis. Prompt CT and MRI examinations and optimal therapeutic management facilitate definitive diagnosis and protect against fatal complications. PMID:22467283

    A small change in brick dimensions resulted in an increase in the perceived work-load of men loading and unloading pallets of bricks by hand. A laboratory study indicated that the change in brick dimensions required changes in grip pattern in order to unload bricks at the same rate, moving the same number at a time. These changed grip patterns resulted in increased upper body movement, increased chest-muscle activity and higher heart rates. These differences were reflected in higher subjective ratings of fatigue. PMID:15676442

    PubMed

    Uggla, Caroline; Mace, Ruth

    2016-02-01

    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.

    McCue, M J; Thompson, J M; Dodd-McCue, D

    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

    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.

    2012-01-01

    The two-staged WWTP 'Gut Grosslappen' has a capacity of 2 mio. PE. It comprises a pre-denitrification in the first stage using recirculation from the nitrifying second stage. A residual post-denitrification in a downstream sand filter is required in order to achieve the effluent standards. Presently the process water from sludge digestion is treated separately by nitrification/denitrification. Due to necessary reconstruction of the biological stages, the process water treatment was included in the future overall process concept of the WWTP. A case study was conducted comparing the processes nitritation/denitrititation and deammonification with nitrification/denitrification including their effect on the operational costs of the planned main flow treatment. Besides the different operating costs the investment costs required for the process water treatment played a significant role. Six cases for the process water treatment were compared. As a result, in Munich deammonification can only be recommended for long-term future developments, due to the high investment costs, compared with the nitritation/denitritation alternative realizable in existing tanks. The savings concerning aeration, sludge disposal and chemicals were not sufficient to compensate for the additional investment costs. Due to the specific circumstances in Munich, for the time being the use of existing tanks for nitritation/denitritation proved to be most economical. PMID:22546808

    I teach an upper-level writing course, Genes, Race, Gender, and Society, designed for Life Science majors, in which I utilize a case study to expose students to ethical ways of thinking. Students first work through the topical case study and then are challenged to rethink their responses through the lenses of ethics, taking into account different ethical frameworks. Students then develop their own case study, integrating ethical components. I want to expose my students to this way of thinking because I see technology being driven by the Jurassic Park phenomenon, "Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should," and want future physicians grounded in a sense of how their actions relate to the greater good.

The goal is to provide additional engineering materials that enhance critical thinking, decision making, and problem solving skills. During this second phase of the project, the Shuttle Case Study Collection website was developed. Extensive HTML coding to link downloadable documents, videos, and images was required, as was training to learn NASA's Content Management System (CMS) for website design. As the final stage of the collection development, the website is designed to allow for distribution of information to the public as well as for case study report submissions from other educators online.

    A familial study of four cases with hypobetalipoproteinemia is reported. Three members are heterozygous and one is homozygous. This congenital fat malabsorption in homozygous state is commonly associated with an absence of serum apoprotein B and LDL. Neuromuscular and ophthalmological signs are absent in this case. The major role of upper digestive endoscopy in the diagnostic procedure is emphasized. Histochemical and immunoenzymatic stains of enterocytes and intestinal organ culture show defective synthesis apo B in the homozygous patient. Studies of DNA polymorphism in the homozygous patient have shown that the apo B gene doesn't certain major insertions or deletions. These results are discussed. PMID:2096430

  11. Distance reporting in digital pathology: A study on 950 cases

    PubMed Central

    Vodovnik, Aleksandar

    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

  12. 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.

  13. Case studies in organic contaminant hydrogeology

    NASA Astrophysics Data System (ADS)

    Baker, John A.

    1989-07-01

    The effective management of domestic solid waste and hazardous, toxic, and radioactive waste is a major problem in the area of environmental geology and water sciences over the world. This series of case studies of organic contaminants from both solid and hazardous waste disposal facilities provides examples of these problems. The facilities were investigated to determine risks and liabilities before acquisition, to determine the site hydrogeologic conditions for design of appropriate groundwater monitoring plans, and/or to determine the potential for groundwater contamination. The results of these studies and investigations by Waste Management Inc. (WMI) and its consultants have shown certain relationships in the distribution of organic pollutants to the different geologic and hydrogeologic charac teristics of each facility. In each of the case studies, all 129 priority pollutants were analyzed in private wells and/or monitoring wells at the request of regulatory agencies. The 31 volatile organic compounds (VOCs) of the priority pollutant list were the majority of the organic compounds detected and these data are evaluated in each case study. The case studies are on disposal facilities located in glacial tills, carbonaceous weathered clay soils, weathered shale, limestone bedrock, dolomite bedrock, and alluvial and sedimentary deposits. A brief discussion of groundwater quality impacts and remedial measures also is included.

  14. Case study examples using self-assessment.

    PubMed

    Garstecki, D; Hutton, C L; Nerbonne, M A; Newman, C W; Smoski, W J

    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.

  15. Governance and management of a deepwater port: a case study

    SciTech Connect

    Olcott, E.S.

    1985-10-01

    A deepwater port is many things to many people. Clearly, the Port of Rotterdam, the largest port in the world, is a deepwater port with its 75 feet of water, more than $1.5 billion invested in facilities and its annual volume of more than 280 million metric tons of cargo in a broad commodity mix. Bantry Bay in Ireland, a major import petroleum and trans-shipment facility for Britain and the European continent, is a deepwater port. So also is the Louisiana Offshore Oil Port (LOOP), comprised of a single-point mooring buoy and sophisticated petroleum distribution system, located in deep water off the Gulf coast of the US. And so is the Port of Seattle a deepwater port, located in the natural deep water of Puget Sound. Deep drafts ports abound in Japan where as many as nine ports have been developed with water depths in excess of 55 feet. The multi-purpose port and industrial island located in Delaware Bay, the case study being scrutinized in this article would also be a deepwater port. The author takes no position in this article on the feasibility of the enterprise. A number of models or options are reviewed on how this project might be organized, managed, and governed if a decision were made to move forward with such an undertaking. 15 references, 2 figures.

    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.

    1990-03-01

    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.

    Mullen, P D

    1985-01-01

    An inductive research method known as grounded theory is described as a means of building conceptual bridges between real-life situations and formal theory. The procedures are detailed and illustrated via two case studies. The first is a study of the social-psychological problem of cutting losses among heart patients through three stages of recovery. The process of extending the theory generated with the heart patients to other invisible physical impairments and across both visible and invisible chronic conditions is outlined. The second case study offers an example of a structurally-oriented theory, developed from participant observations of the processes of managing patients, staff, and neighbors for an "antipsychiatric" treatment facility for juvenile schizophrenics.

    Background Publicly funded clinical trials require a substantial commitment of time and money. To ensure that sufficient numbers of patients are recruited it is essential that they address important questions in a rigorous manner and are managed well, adopting effective marketing strategies. Methods Using methods of analysis drawn from management studies, this paper presents a structured assessment framework or reference model, derived from a case analysis of the MRC's CRASH trial, of 12 factors that may affect the success of the marketing and sales activities associated with clinical trials. Results The case study demonstrates that trials need various categories of people to buy in – hence, to be successful, trialists must embrace marketing strategies to some extent. Conclusion The performance of future clinical trials could be enhanced if trialists routinely considered these factors. PMID:18028537

    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

    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.

    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.

    2001-01-01

    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

  20. 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.

    1999-12-14

    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.

    The teaching of biomaterials as case study by on-line platform , susceptible to develop both individually and in groups, got different objectives proposed by the European Higher Education System, among which include: participate actively in the teaching-learning process by students, interpreting situations, adapt processes and solutions. 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.

    PubMed

    Dolinska, Barbara

    2013-01-01

    According to evolutionary explanations men hardly ever are absolutely certain about their biological fatherhood therefore they must seek various sources of information to subjectively establish whether they are the genetic fathers of the children they raise. Apicella and Marlowe (2004) showed that fathers who perceived greater similarity between their children and themselves were willing to invest more resources (e.g., time, money, care) in their offspring presumably because the perceived resemblance indicated to the fathers their genetic relatedness with their children. The present study extended the design of Apicella and Marlowe's original study and included both fathers and mothers as participants. Parents were recruited by a female confederate at the airport and at the railway station in Wroclaw (Poland). Multiple regression analyses showed that perceived resemblance predicted parental investment in the child for both men and women. The fact that mothers' declarations of investment in their children also depended on the perceived resemblance factor is not consistent with evolutionary formulations delineated by Apicella and Marlowe (2004; 2007). Future studies must resolve the issue of whether the resemblance-investment relation in fathers results from men relaying on child's resemblance to themselves as an indicator of their own biological paternity, or whether it results from the more parsimonious phenomenon that people in general are attracted more to other people who are similar to them.

    Twelve cases of chronic urticaria with histopathologic features of lecocitoclastic allergic angitis are studied. The type of cutaneous lesion, personal and familiar atopic history and the presence of autoimmune disease are described. Light microscopy, direct immunofluorescence, anti DNA, antinuclear, antithyroid, Ro, La, Rnp and Sm antibodies, total complement levels, C3 and C4, rheumatoid factor, latex, ASTO, cryoglobulines and complete workup were investigated, taking into account natural progression and response to therapy. Two different groups are defined: 1) normocomplementemic (5 patients) and 2) hypocomplementemic (7 patients). They were all women except one. The cutaneous lesions were indistinguishable in the two groups. Only in the second group there was an associated disease (systemic lupus erythematosus, Sjogren syndrome disease, lupus-Sjogren overlap, autoimmune thyroid disease). Urticaria had been present from the onset of the disease in 4 patients, and occurred later during its course in 8 others. Five patients had thyroid disease (Hashimoto thyroiditis or Graves disease), two of them being mother and daughter. Another patient had a family history of Grave's disease and urticaria. Anti DNA antibodies were found in 7 cases, and anti Ro + La + in 3 cases. Response to treatment was variable with spontaneous cycles of worsening and remissions. One of the patients found a relationship with certain foods. Histopathologic results are related in both clinical normocomplementemic and hypocomplementemic groups. No significant differences were found between the two groups, but Ro+ and La+ patients exhibit more intense cariorexis and neutrophilic infiltrates. PMID:2263094

    Over the last few decades much research has been done into the raised level of psychiatric comorbidity in epilepsy. On the basis of a case study of a patient suffering from post-ictal psychoses we explain the psychiatric differential diagnosis within the framework of epilepsy and we investigate the frequent psychiatric side-effects of anticonvulsants. It is concluded that the links between epilepsy and psychiatric symptoms are complex and that the neuropsychiatry of epilepsy is concerned with syndromes that are unique and do notfit into modern psychiatric classification systems.

    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.

Despite the harsh weather on the island, after the first 6 months of operation, laboratory analyses of soil samples indicated a significant (80%) reduction in diesel concentrations.

    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.

    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.

    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.

    In order to “restore the high priority that science and technology had previously been afforded in the federal budget,” and “to invest in the future of the United States,” Senator Phil Gramm (R-Texas) recently proposed that the U.S. government double its investment in “basic” science and biomedical research. On January 21, Gramm introduced the National Research Investment Act of 1997 (S. 124), a bill to increase funding for nondefense research from $32.5 billion in 1997 to $65 billion by 2007.

    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.

  9. Socially responsible investing. Is it successful?

    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

    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.

    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.

    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

    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 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.

    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

    We show, through several selected case studies, the potential benefits that can be obtained by controlling the polarization states of the exciting and scattered radiations in a Raman scattering experiment. When coupled with polarization control, Raman spectroscopy is thus capable of providing extra information on the structural properties of the materials under investigation. The experimental examples presented in this work are taken from the area of both conventional, i.e., far-field, as well as from near-field Raman spectroscopy. They cover topics such as the stress tensor measurement in strained semiconductor structures, the vibration mode assignment in pentacene thin films and the Raman scattering tensor determination from near-field measurements on azobenzene monolayers. The basic theory necessary for modelling the far- and near-field polarized Raman responses is also given and the model efficiency is illustrated on the experimental data.

    This descriptive case study illustrates the experiences of a 55-year-old male with a chronic disability resulting from a stroke, living in the community and a clinician's trial using occupation-based interventions predominately in a rehabilitation setting. The participant engaged in occupation-based interventions three times a week for 5 weeks guided by the Canadian Occupational Performance Measure (COPM). Data were collected through semi-structured interviews during the intervention sessions and journal entries made by the therapist. Results suggested occupation-based interventions facilitated a transformation for both the client and the therapist by enhancing the participant's occupational performance and the ability to resume previous roles. The therapist's belief in the power and value of occupation-based practice was reinforced and validated, particularly in the rehabilitation of an individual with chronic stroke. PMID:24867352

    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.

    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.

    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

    PubMed Central

    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.

    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

    This paper is a case study of the Union of Raba River Communities in Poland. The City of Cracow receives 60% of its water from the Dobczyce Reservoir, which is located in the Raba River Watershed. The water quality in this reservoir is threatened by pollution from non-point sources and untreated sewage. Because the reservoir and watershed are located outside of Cracow, protecting the water quality falls to communities that do not use the Reservoir. To meet this responsibility, communities in the watershed formed the Union of Raba River Communities (the Union). The Union hired a Cracow consulting firm to conduct a study of watershed management options, which was completed in January 1996. The Union is now evaluating the plan and looking for funding for implementation. The Union is also addressing specific problems in the watershed, including the siting of a much needed but unpopular landfill. There are numerous sources of pollution in the watershed including: sewage; runoff from urban areas, roads, agriculture, logged areas, landfills and dumps, fertilizer and pesticide storage areas, and petrol stations; and air pollution.

    Flooding is a consequence of the prevailing meteorological situation, the intensity and duration of precipitation, geomorphology, human activities over a geographical region and other factors. Floods result in damage and destruction of infrastructure and private property and, in some cases, in fatalities. Flash floods are sudden and quite localized in extend, characterized by excessive amounts of rainfall within a short period of time and are distinguished from other floods by their degree of severity. The broader knowledge concerning flash floods is useful for the better understanding of the underlying thermodynamic and dynamic mechanisms, as well as the associated physical processes. The wider understanding of flashfloods can form part of an integrated system for short and very short forecasting of these events. In the present study, the synoptic, dynamic and thermodynamic conditions during the development of a baroclinic depression which affected the area of Cyprus on 6 November 2005 are studied. The depression was associated with extreme weather phenomena, such as thunderstorms, a water spout and high precipitation accumulations. The results indicate the importance of the dynamic parameters in the system's development and the thermodynamic analysis has shown the convective potential of the atmosphere.

    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.

    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.

    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.

    Wetlands are reputed to reduce peak flows and improve water quality by trapping sediment and phosphorus. However, there are relatively few studies that quantify these wetland functions. This paper reports on a study of a 45-hectare wetland in southern Wisconsin. The wetland is traversed by a stream channel that drains a predominantly agricultural 17.4 km2 watershed. During the spring and summer of 2006, we collected stage data and water samples at stations upstream and downstream of the wetland, with the former accounting for 82% of the contributing area. Continuous measurements of water stage at these stations were used to construct a streamflow record. During storm events water samples were taken automatically at 2-hour intervals for the first 12 samples and 8-hour intervals for the next 12 samples. Samples were analyzed for total suspended solids, total phosphorus, and dissolved reactive phosphorus. Ten events were observed during the observation period; the two largest events were 1 to 2-year storms. One-dimensional unsteady flow routing was used to estimate the maximum extent of wetland inundation for each event. When normalized for flow volume, all peak flows were attenuated by the wetland, with the maximum attenuation corresponding to the intermediate events. The reduced attenuation of the larger events appears to be due to filling of storage, either due to antecedent conditions or the event itself. In the case of sediment, the amount leaving the wetland in the two largest storms, which accounted for 96% of the exported sediment during the period of observation, was twice the amount entering the wetland. The failure of the wetland to trap sediment is apparently due to the role of drainage ditches, which trap sediment during the wetland-filling phase and release it during drainage. The export of sediment during the largest events appears to result from remobilization of sediment deposited in the low-gradient stream channel during smaller events. This

    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.

    2003-12-01

    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.

    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.

    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.

    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.

    2007-01-01

    A case study of a rare form of synesthesia is presented, where specific words act as the inducer, and gustatory sensations function as the concurrent. The female participant (TD) was twice presented with a list of 806 English words and 222 grammatically correct non-words (with 3 months between presentations). For each presentation, TD was asked to provide: a subjective description of the gustatory experience (if any) associated with each stimulus; a rating (from 0 to 10) of the intensity of the gustatory experience; and an indication (yes/no) if the experience was aversive. TD's responses across the two presentations were quantified, and comparisons are provided. In addition, TD's ability to create and recall novel word-taste associations was compared to that demonstrated by a sample of ten age-matched non-synesthete females. TD's synesthetic experiences were found to be highly consistent, more common in English words than non-words, and rarely aversive. Although TD was superior to control participants in remembering novel word-taste associations, her reported experiences cannot be wholly explained by either an exceptional non-synesthetic learning of taste-word associations over time, or a clear response to phonemes, rather than whole words. These conclusions are compared to the five other published reports of word-gustatory synesthesia, and directions for future research are discussed. PMID:17564196

    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.

  5. Water market transfers in South Africa: Two case studies

    Nieuwoudt, W. L.; Armitage, R. M.

    2004-09-01

    Statistical analyses (discriminant, logit, and principal components) of water transfers in the Lower Orange River showed that water rights were transferred to farmers with the highest return per unit of water applied, those producing table grapes, and with high-potential arable "outer land" without water rights. Only unused water (sleeper right) was transferred, while water saved (through adoption of conservation practices) was retained possibly for security purposes. A second study in the Nkwaleni Valley in northern KwaZulu-Natal found that no water market had emerged despite the scarcity of water in the area. No willing sellers of water rights existed. Demand for institutional change to establish tradable water rights may take more time in the second area since crop profitability in this area is similar for potential buyers and nonbuyers. Transaction costs appear larger than benefits from market transactions. Farmers generally use all their water rights in the second area and retain surplus water rights as security against drought because of unreliable river flow. This study indicates that these irrigation farmers are highly risk averse (downside risk). Government policies that increase the level of risk and reduce security of licenses are estimated to have a significant effect on future investment in irrigation. In an investment model the following variables explain future investment: expected profits, liquidity, risk aversion (Arrow-Pratt), and security of water use rights. The study is seen in the light of the New South African Water Act of 1998. According to this act, the ownership of water in South Africa has changed from private to public. This reform may not impede the development of water markets in South Africa since in the well-developed water markets of the United States, western states claim ownership of water within their boundaries. All states in the western United States allow private rights in the use of water to be established and sold.

  6. Ada software productivity prototypes: A case study

    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.

    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

    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

  15. Combining genetic association study designs: a GWAS case study.

    Estus, Janice L; Fardo, David W

    2013-01-01

    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

  16. Biostratigraphic case studies of six major extinctions

    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.

    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

    2007-01-01

    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

    2010-05-01

    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

  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.

    PubMed

    Poustie, Michael S; Deletic, Ana

    2014-12-01

    Developing countries struggle to provide adequate urban water services, failing to match infrastructure with urban expansion. Despite requiring an improved understanding of alternative infrastructure performance when considering future investments, integrated modeling of urban water systems is infrequent in developing contexts. This paper presents an integrated modeling methodology that can assist strategic planning processes, using Port Vila, Vanuatu, as a case study. 49 future model scenarios designed for the year 2050, developed through extensive stakeholder participation, were modeled with UVQ (Urban Volume and Quality). The results were contrasted with a 2015 model based on current infrastructure, climate, and water demand patterns. Analysis demonstrated that alternative water servicing approaches can reduce Port Vila's water demand by 35 %, stormwater generation by 38 %, and nutrient release by 80 % in comparison to providing no infrastructural development. This paper demonstrates that traditional centralized infrastructure will not solve the wastewater and stormwater challenges facing rapidly growing urban cities in developing countries. PMID:24973053

    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.

    PubMed

    Harvey, Gill; Marshall, Rhianon J; Jordan, Zoe; Kitson, Alison L

    2015-11-01

    Debates about knowledge translation (KT) typically focus on the research-practice gap, which appears to be premised on the assumption that academics are a homogeneous collective, sharing a common view. We argue that a number of hidden barriers need to be addressed related to the understanding, interpretation, ability, and commitment to translate knowledge within academic communities. We explore this by presenting a qualitative case study in a health sciences faculty. Applying organizational and management theory, we discuss different types of boundaries and the resultant barriers generated, ranging from diversity in understanding and perceptions of KT to varying motivations and incentives to engage in translational activity. We illustrate how we are using the empirical findings to inform the development of a KT strategy that targets the identified barriers. Investing in this internal KT-focused activity is an important step to maximize the potential of future collaborations between producers and users of research in health care. PMID:25847856

    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.

    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. PMID:20868336

    NASA Astrophysics Data System (ADS)

    2005-12-01

    Scientist-teacher partnerships provide opportunities for scientists to become better educators and teachers to increase their science content knowledge, but few accounts exist about how partnerships evolve and why some succeed and others fail. We investigated these questions in the context of an NSF GK-12 program that pairs graduate and undergraduate science and math students (fellows) with K-12 teachers. Using a variety of data sources, we found several patterns that were influential across the majority of partnerships. Aligned, partnership-centered goals and expectations were most conducive to productive relationships. A desire and commitment to collaborate and a willingness to communicate openly were also essential. Differences in the rigidity and intensity of the K-12 and university schedules and working with multiple teachers made collaboration difficult due to lack of planning time. Mutual investment manifested itself in several ways among partnerships including collaboration on teaching, planning, and other classroom activities, exchange of resources, and exchange of constructive feedback. Fellows and teachers were most likely to invest themselves when they perceived that their contributions were invited and appreciated in and out of the classroom. In all cases, role ambiguity was a major barrier to partnership formation. Fellows employed numerous strategies to define their roles, but working collaboratively was possible only when roles were discussed and allowed to evolve. Fellows and teachers found it difficult to communicate directly about dissatisfaction. While each partnership was unique, these major patterns influencing the success of a partnership occur in many situations and thus appear transferable. Regardless of outcome, partners felt as though they benefited significantly from this experience. Our results may be applied to similar partnership programs to improve project design and enhance the sustainability of relationships between scientists and

  6. A case study of preferential bestiality.

    PubMed

    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.

    Karpinski, J P

    1997-02-01

    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. PMID:10164878

  16. The most influential investment.

    PubMed

    Summers, L

    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

  17. 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.

    We report the case of a 14-year-old boy with bilateral congenital perisylvian syndrome as evidenced by polymicrogyria in the left and right frontotemporal regions, pseudobulbar paresis, seizures, and spastic diplegia. This is the first description of comprehensive neuropsychological assessment in a child with this syndrome. The results reflect significant impairments in auditory processing and independent learning and retention, but relatively preserved cognitive performance on interactive tasks involving frequent feedback and redirection. The findings are interpreted in the context of the neuropathology of this syndrome, with an emphasis on pragmatic implications for rehabilitation. PMID:18618376

    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. PMID:11803597

    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

    An ectopic kidney is a rare congenital anomaly that occurs when the kidney fails to ascend to its normal position. Often an ectopic kidney is asymptomatic and the kidney is an unexpected finding during organ recovery. The kidney described in this case report had normal function and could have been used for transplantation, if it had been recovered without 2 renal arteries being damaged because of anatomic variation. The renal vasculature in this type of abnormality usually ascends from the iliac vessels, and this variation in anatomy should be taken into consideration by the recovering surgeon during arterial cannulation for organ flushing.

    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.

    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

    The port of Rotterdam, The Netherlands, is the world's largest container port. In 2006, one of these containers caused a chemical incident. Methylbromide is used in some countries as a pesticide for the fumigation of maritime containers. Because of an insufficiently performed detoxification, this insecticide intoxicated several employees and some of the ambulance crew and Mobile Medical Team (MMT). The victims displayed symptoms of sore throat, irritated eyes, and hypersalivation. One of the victims suffered from multiple epileptic seizures. Two victims were admitted to the intensive care unit for respiratory support. Three other employees showed milder symptoms and received supportive care but were not admitted to the hospital. This complicated case shows that the safety of the ambulance crew and MMT must be guaranteed. It also demonstrates that healthcare providers cannot always oversee the accident scene and that there are some pitfalls that are almost impossible to prevent. PMID:20118865

    2009-02-01

    Cornelia de Lange syndrome (CDLS) is a relatively common multiple congenital anomaly/mental retardation disorder with an unknown genetic and molecular pathogenesis. The essential features of this developmental malformation syndrome are retardation in growth, developmental delay, various structural limb abnormalities, and distinctive facial features. Most cases are sporadic and are thought to result from a new dominant mutation. Consequently, hypotheses regarding the pathogenetic mechanisms underlying the two distinct phenotypes, classic and mild, are purely speculative. The recent discovery of molecular techniques and identification of the NIPBL gene has allowed etiologic diagnosis of this disorder. In this article, we describe a patient with CDLS in whom conventional cytogenetics, fluorescence in situ hybridization, and NIPBL gene mutation analysis determined an etiologic diagnosis, providing precise genetic counseling and facilitated the family to make an evidence-based decision for conception and also alleviated the extreme degree of anxiety associated with the thought of having a second child in this set of circumstances.

    This paper gives details of a recent court case conducted in Australia concerning a compensation claim made by a radar technician for subcapsular posterior cataracts allegedly caused by exposure to microwave radiation. A discussion of some relevant material, including the likely invalidation of certain in vivo ocular exposures due to the use of a metallic cannula and the relevance of in vitro exposures of rat lenses, are presented. The key findings of the court are also summarized. The ruling of the court was that it was probable that the level of microwave exposure did not cause, or accelerate the development of, the cataracts or contribute to doing so. Consequently, the claim was dismissed. PMID:2529231

    2006-01-01

    Statistical process control (SPC) charts can be applied to a wide number of health care applications, yet widespread use has not occurred. The greatest obstacle preventing wider use is the lack of quality management training that health care workers receive. The technical nature of the SPC guarantees that without explicit instruction this technique will not come into widespread use. Reviews of health care quality management texts inform the reader that SPC charts should be used to improve delivery processes and outcomes often without discussing how they are created. Conversely, medical research frequently reports the improved outcomes achieved after analyzing SPC charts. This article is targeted between these 2 positions: it reviews the SPC technique and presents a tool and data so readers can construct SPC charts. After tackling the case, it is hoped that the readers will collect their own data and apply the same technique to improve processes in their own organization. PMID:17047496

    Here we describe the first documented case of congenital amusia in childhood. AS is a 10-year-old girl who was referred to us by her choir director for persisting difficulties in singing. We tested her with the child version of the Montreal Battery for the Evaluation of Amusia (MBEA) which confirmed AS's severe problems with melodic and rhythmic discrimination and memory for melodies. The disorder appears to be limited to music since her audiometry as well as her intellectual and language skills are normal. Furthermore, the musical disorder is associated to a severe deficit in detecting small pitch changes. The electrical brain responses point to an anomaly in the early stages of auditory processing, such as reflected by an abnormal mismatch negativity (MMN) response to small pitch changes. In singing, AS makes more pitch than time errors. Thus, despite frequent and regular musical practice, AS's profile is similar to the adult form of congenital amusia. PMID:21453912

  19. Evaluating clinical periodontal measures as surrogates for bacterial exposure: The Oral Infections and Vascular Disease Epidemiology Study (INVEST)

    PubMed Central

    2010-01-01

    Background Epidemiologic studies of periodontal infection as a risk factor for cardiovascular disease often use clinical periodontal measures as a surrogate for the underlying bacterial exposure of interest. There are currently no methodological studies evaluating which clinical periodontal measures best reflect the levels of subgingival bacterial colonization in population-based settings. We investigated the characteristics of clinical periodontal definitions that were most representative of exposure to bacterial species that are believed to be either markers, or themselves etiologic, of periodontal disease. Methods 706 men and women aged ≥ 55 years, residing in northern Manhattan were enrolled. Using DNA-DNA checkerboard hybridization in subgingival biofilms, standardized values for Aggregatibacter actinomycetemcomitans, Porphyromonas gingivalis, Treponema denticola and Tannerella forsythia were averaged within mouth and summed to define "bacterial burden". Correlations of bacterial burden with clinical periodontal constructs defined by the severity and extent of attachment loss (AL), pocket depth (PD) and bleeding on probing (BOP) were assessed. Results Clinical periodontal constructs demonstrating the highest correlations with bacterial burden were: i) percent of sites with BOP (r = 0.62); ii) percent of sites with PD ≥ 3 mm (r = 0.61); and iii) number of sites with BOP (r = 0.59). Increasing PD or AL severity thresholds consistently attenuated correlations, i.e., the correlation of bacterial burden with the percent of sites with PD ≥ 8 mm was only r = 0.16. Conclusions Clinical exposure definitions of periodontal disease should incorporate relatively shallow pockets to best reflect whole mouth exposure to bacterial burden. PMID:20056008

    Sukuk Musyarakah is one of several instruments of Islamic bond investment in Malaysia, where the form of this sukuk is actually based on restructuring the conventional bond to become a Syariah compliant bond. The Syariah compliant is based on prohibition of any influence of usury, benefit or fixed return. Despite of prohibition, daily returns of sukuk are non-fixed return and in statistic, the data of sukuk returns are said to be a time series data which is dependent and autocorrelation distributed. This kind of data is a crucial problem whether in statistical and financing field. Returns of sukuk can be statistically viewed by its volatility, whether it has high volatility that describing the dramatically change of price and categorized it as risky bond or else. However, this crucial problem doesn't get serious attention among researcher compared to conventional bond. In this study, MCEWMA chart in Statistical Process Control (SPC) is mainly used to monitor autocorrelated data and its application on daily returns of securities investment data has gained widespread attention among statistician. However, this chart has always been influence by inaccurate estimation, whether on base model or its limit, due to produce large error and high of probability of signalling out-of-control process for false alarm study. To overcome this problem, a bootstrap approach used in this study, by hybridise it on MCEWMA base model to construct a new chart, i.e. Bootstrap MCEWMA (BMCEWMA) chart. The hybrid model, BMCEWMA, will be applied to daily returns of sukuk Musyarakah for Rantau Abang Capital Bhd. The performance of BMCEWMA base model showed that its more effective compare to real model, MCEWMA based on smaller error estimation, shorter the confidence interval and smaller false alarm. In other word, hybrid chart reduce the variability which shown by smaller error and false alarm. It concludes that the application of BMCEWMA is better than MCEWMA.

  17. Knowledge Co-production at the Research-Practice Interface: Embedded Case Studies from Urban Forestry

    Cities are increasingly engaging in sustainability efforts and investment in green infrastructure, including large-scale urban tree planting campaigns. In this context, researchers and practitioners are working jointly to develop applicable knowledge for planning and managing the urban forest. This paper presents three case studies of knowledge co-production in the field of urban forestry in the United States. These cases were selected to span a range of geographic scales and topical scopes; all three are examples of urban researcher-practitioner networks in which the authors are situated to comment on reflexively. The three cases resemble institutional structures described in the knowledge co-production literature, including participatory research, a hybrid organization of scientists and managers, and a community of practice. We find that trust, embeddedness, new approaches by both practitioners and researchers, and blending of roles all serve to recognize multiple forms of capability, expertise, and ways of knowing. We discuss the impacts of knowledge co-production and the ways in which hybrid institutional forms can enable its occurrence.

  19. Probabilistic modeling of solidification grain structure in investment castings

    A probabilistic approach for modeling the evolution of grain structure in investment castings has been developed. The approach differs from the classical Monte Carlo simulations of microstructural evolution in that it uses the results from a heat transfer simulation of the investment casting process for determining the probabilities of nucleation and growth. The model was used to predict the solidification grain structure in castings. The model is quasi-3D, since it uses the information from a 3D simulation of heat transfer to predict the grain structure developed in any 2D-section of the casting. Structural transitions such as columnar/equiaxed transition can also be predicted, using suitable transition criteria. Results from the model have been validated by comparison with actual micrographs from experimental investment castings. In the first case, simulations were performed for a simple plate shaped casting of superalloy Rene 77. The effects of mold insulation as well as metal pour and mold preheat temperatures on the grain size of the casting were studied. In the second example, the casting of a complex-shaped jet engine component made of superalloy IN718 was simulated. Simulation results were seen to match very well with experiments.
