The Lunar Soil Particle Separator (LSPS) beneficiates soil prior to in situ resource utilization (ISRU). It can improve ISRU oxygen yield by boosting the concentration of ilmenite, or other iron-oxide-bearing materials found in lunar soils, which can substantially reduce hydrogen reduction reactor size, as well as drastically decreasing the power input required for soil heating

Traumatic brain injury rehabilitation: case management and insurance-related issues.

PubMed

Pressman, Helaine Tobey

2007-02-01

Traumatic brain injury (TBI) cases are medically complex, involving the physical, cognitive, behavioral, social, and emotional aspects of the survivor. Often catastrophic, these cases require substantial financial resources not only for the patient's survival but to achieve the optimal outcome of a functional life with return to family and work responsibilities for the long term. TBI cases involve the injured person, the family, medical professionals such as treating physicians, therapists, attorneys, the employer, community resources, and the funding source, usually an insurance company. Case management is required to facilitate achievement of an optimal result by collaborating with all parties involved, assessing priorities and options, coordinating services, and educating and communicating with all concerned.

The Joint Military Medical Executive Skills initiative: an impressive response to changing human resource management rules of engagement.

PubMed

Kerr, Bernard J

2007-01-01

Confronted with a sudden and substantial change in the rules regarding who could command a military medical treatment facility (MTF), the Military Health System (MHS) responded to the challenge with an impressive human resource management solution-the Joint Medical Executive Skills Program. The history, emergence, and continuing role of this initiative exemplifies the MHS's capacity to fulfill the spirit and intent of an arduous Congressional mandate while enhancing professional development and sustaining the career opportunities of medical officers. The MHS response to the Congressional requirement that candidates for MTF command demonstrate professional administrative skills was decisive, creative, and consistent with the basic principles of human resource management. The Joint Medical Executive Skills Program is a management success story that demonstrates how strategic planning, well-defined skills requirements, and structured training can assure a ready supply of qualified commanders for the military's MTFs.

The last two decades have seen substantially increased potential for quantitative social science research. This has been made possible by the significant expansion of publicly available social science datasets, the development of new analytical methodologies, such as microsimulation, and increases in computing power. These rich resources do, however, bring with them substantial challenges associated with organizing and using data. These processes are often referred to as 'data management'. The Data Management through e-Social Science (DAMES) project is working to support activities of data management for social science research. This paper describes the DAMES infrastructure, focusing on the data-fusion process that is central to the project approach. It covers: the background and requirements for provision of resources by DAMES; the use of grid technologies to provide easy-to-use tools and user front-ends for several common social science data-management tasks such as data fusion; the approach taken to solve problems related to data resources and metadata relevant to social science applications; and the implementation of the architecture that has been designed to achieve this infrastructure.

Estimating the Cost of Providing Foundational Public Health Services.

2017-12-28

To estimate the cost of resources required to implement a set of Foundational Public Health Services (FPHS) as recommended by the Institute of Medicine. A stochastic simulation model was used to generate probability distributions of input and output costs across 11 FPHS domains. We used an implementation attainment scale to estimate costs of fully implementing FPHS. We use data collected from a diverse cohort of 19 public health agencies located in three states that implemented the FPHS cost estimation methodology in their agencies during 2014-2015. The average agency incurred costs of $48 per capita implementing FPHS at their current attainment levels with a coefficient of variation (CV) of 16 percent. Achieving full FPHS implementation would require $82 per capita (CV=19 percent), indicating an estimated resource gap of $34 per capita. Substantial variation in costs exists across communities in resources currently devoted to implementing FPHS, with even larger variation in resources needed for full attainment. Reducing geographic inequities in FPHS may require novel financing mechanisms and delivery models that allow health agencies to have robust roles within the health system and realize a minimum package of public health services for the nation. © Health Research and Educational Trust.

RAINBOW LAKE WILDERNESS AND FLYNN LAKE WILDERNESS STUDY AREA, WISCONSIN.

The Rainbow Lake Wilderness and Flynn Lake Wilderness study area in Wisconsin are contiguous and were studied as a unit. The rainbow Lake Wilderness contains a demonstrated resource of about 210,000 tons of commercial-quality peat in an area of substantiated peat resource potential. The Flynn Lake Wilderness study area contains a demonstrated resource of about 300,000 tons of commercial-quality peat in an area of substantiated peat resource potential. These deposits, however, are of limited importance because larger deposits of similar material are abundant outside the areas, closer to present markets. Rocks in the subsurface contain a low-grade copper resource identified by mining company exploration drilling. Although this is an area of substantiated copper resource potential, it is a low-grade resource, thin and generally at great depth.

2012-01-01

Building cognitive abilities often requires sustained engagement with effortful tasks. We demonstrate that beliefs about willpower-whether willpower is viewed as a limited or non-limited resource-impact sustained learning on a strenuous mental task. As predicted, beliefs about willpower did not affect accuracy or improvement during the initial phases of learning; however, participants who were led to view willpower as non-limited showed greater sustained learning over the full duration of the task. These findings highlight the interactive nature of motivational and cognitive processes: motivational factors can substantially affect people's ability to recruit their cognitive resources to sustain learning over time.

Optimising the performance of an outpatient setting.

Sendi, Pedram; Al, Maiwenn J; Battegay, Manuel; Al Maiwenn, J

2004-01-24

An outpatient setting typically includes experienced and novice resident physicians who are supervised by senior staff physicians. The performance of this kind of outpatient setting, for a given mix of experienced and novice resident physicians, is determined by the number of senior staff physicians available for supervision. The optimum mix of human resources may be determined using discrete-event simulation. An outpatient setting represents a system where concurrency and resource sharing are important. These concepts can be modelled by means of timed Coloured Petri Nets (CPN), which is a discrete-event simulation formalism. We determined the optimum mix of resources (i.e. the number of senior staff physicians needed for a given number of experienced and novice resident physicians) to guarantee efficient overall system performance. In an outpatient setting with 10 resident physicians, two staff physicians are required to guarantee a minimum level of system performance (42-52 patients are seen per 5-hour period). However, with 3 senior staff physicians system performance can be improved substantially (49-56 patients per 5-hour period). An additional fourth staff physician does not substantially enhance system performance (50-57 patients per 5-hour period). Coloured Petri Nets provide a flexible environment in which to simulate an outpatient setting and assess the impact of any staffing changes on overall system performance, to promote informed resource allocation decisions.

Integral Images: Efficient Algorithms for Their Computation and Storage in Resource-Constrained Embedded Vision Systems

The integral image, an intermediate image representation, has found extensive use in multi-scale local feature detection algorithms, such as Speeded-Up Robust Features (SURF), allowing fast computation of rectangular features at constant speed, independent of filter size. For resource-constrained real-time embedded vision systems, computation and storage of integral image presents several design challenges due to strict timing and hardware limitations. Although calculation of the integral image only consists of simple addition operations, the total number of operations is large owing to the generally large size of image data. Recursive equations allow substantial decrease in the number of operations but require calculation in a serial fashion. This paper presents two new hardware algorithms that are based on the decomposition of these recursive equations, allowing calculation of up to four integral image values in a row-parallel way without significantly increasing the number of operations. An efficient design strategy is also proposed for a parallel integral image computation unit to reduce the size of the required internal memory (nearly 35% for common HD video). Addressing the storage problem of integral image in embedded vision systems, the paper presents two algorithms which allow substantial decrease (at least 44.44%) in the memory requirements. Finally, the paper provides a case study that highlights the utility of the proposed architectures in embedded vision systems. PMID:26184211

To develop projections of the resources required (person-years of drug supply and healthcare worker time) for universal access to antiretroviral treatment (ART) in Zimbabwe. A stochastic mathematical model of disease progression, diagnosis, clinical monitoring and survival in HIV infected individuals. The number of patients receiving ART is determined by many factors, including the strategy of the ART programme (method of initiation, frequency of patient monitoring, ability to include patients diagnosed before ART became available), other healthcare services (referral rates from antenatal clinics, uptake of HIV testing), demographic and epidemiological conditions (past and future trends in incidence rates and population growth) as well as the medical impact of ART (average survival and the relationship with CD4 count when initiated). The variations in these factors lead to substantial differences in long-term projections; with universal access by 2010 and no further prevention interventions, between 370 000 and almost 2 million patients could be receiving treatment in 2030-a fivefold difference. Under universal access, by 2010 each doctor will initiate ART for up to two patients every day and the case-load for nurses will at least triple as more patients enter care and start treatment. The resources required by ART programmes are great and depend on the healthcare systems and the demographic/epidemiological context. This leads to considerable uncertainty in long-term projections and large variation in the resources required in different countries and over time. Understanding how current practices relate to future resource requirements can help optimise ART programmes and inform long-term public health planning.

The Arab perspective of the current energy situation is discussed, during which Mr. Ghobash points out that a truly interdependent relationship exists between the U.S. and the Arab world and that all countries need to learn to exchange their resources cooperatively. The Arab world has 60 percent of the world's current oil exports, but it needs Western manpower and technical assistance for economic development. The United Arab Emirates needs to transform its economy and raise its standard of living, each of which requires exporting a substantial amount of its depletable oil resources. The lifespan of these resources is estimated atmore » 30 to 50 years. But the country is investing income from these oil resources to diversify its narrowly based economic structures so that future generations will have a higher standard of living. (MCW)« less

To determine costs for adverse event (AE) procedures for a large HIV perinatal trial by analyzing actual resource consumption using activity-based costing (ABC) in an international research setting. The AE system for an ongoing clinical trial in Uganda was evaluated using ABC techniques to determine costs from the perspective of the study. Resources were organized into cost categories (eg, personnel, patient care expenses, laboratory testing, equipment). Cost drivers were quantified, and unit cost per AE was calculated. A subset of time and motion studies was performed prospectively to observe clinic personnel time required for AE identification. In 18 months, there were 9028 AEs, with 970 (11%) reported as serious adverse events. Unit cost per AE was $101.97. Overall, AE-related costs represented 32% ($920,581 of $2,834,692) of all study expenses. Personnel ($79.30) and patient care ($11.96) contributed the greatest proportion of component costs. Reported AEs were predominantly nonserious (mild or moderate severity) and unrelated to study drug(s) delivery. Intensive identification and management of AEs to conduct clinical trials ethically and protect human subjects require expenditure of substantial human and financial resources. Better understanding of these resource requirements should improve planning and funding of international HIV-related clinical trials.

Optimization of cDNA-AFLP experiments using genomic sequence data.

cDNA amplified fragment length polymorphism (cDNA-AFLP) is one of the few genome-wide level expression profiling methods capable of finding genes that have not yet been cloned or even predicted from sequence but have interesting expression patterns under the studied conditions. In cDNA-AFLP, a complex cDNA mixture is divided into small subsets using restriction enzymes and selective PCR. A large cDNA-AFLP experiment can require a substantial amount of resources, such as hundreds of PCR amplifications and gel electrophoresis runs, followed by manual cutting of a large number of bands from the gels. Our aim was to test whether this workload can be reduced by rational design of the experiment. We used the available genomic sequence information to optimize cDNA-AFLP experiments beforehand so that as many transcripts as possible could be profiled with a given amount of resources. Optimization of the selection of both restriction enzymes and selective primers for cDNA-AFLP experiments has not been performed previously. The in silico tests performed suggest that substantial amounts of resources can be saved by the optimization of cDNA-AFLP experiments.

Requirements Development Issues for Advanced Life Support Systems: Solid Waste Management

Levri, Julie A.; Fisher, John W.; Alazraki, Michael P.; Hogan, John A.

2002-01-01

Long duration missions pose substantial new challenges for solid waste management in Advanced Life Support (ALS) systems. These possibly include storing large volumes of waste material in a safe manner, rendering wastes stable or sterilized for extended periods of time, and/or processing wastes for recovery of vital resources. This is further complicated because future missions remain ill-defined with respect to waste stream quantity, composition and generation schedule. Without definitive knowledge of this information, development of requirements is hampered. Additionally, even if waste streams were well characterized, other operational and processing needs require clarification (e.g. resource recovery requirements, planetary protection constraints). Therefore, the development of solid waste management (SWM) subsystem requirements for long duration space missions is an inherently uncertain, complex and iterative process. The intent of this paper is to address some of the difficulties in writing requirements for missions that are not completely defined. This paper discusses an approach and motivation for ALS SWM requirements development, the characteristics of effective requirements, and the presence of those characteristics in requirements that are developed for uncertain missions. Associated drivers for life support system technological capability are also presented. A general means of requirements forecasting is discussed, including successive modification of requirements and the need to consider requirements integration among subsystems.

The FBS Program indicated that applications of advanced technology can result in an improved FBS that will satisfy the requirements defined by municipal fire departments. To accomplish this technology transfer, a substantial commitment of resources over an extended period of time has been required. This program has indicated that the ability of NASA in terms of program management such as requirement definition, system analysis, and industry coordination may play as important a role as specific sources of hardware technology. As a result of the FBS program, a sequence of milestones was passed that may have applications as generalized milestones and objectives for any technical application program.

Assessment of the regional economic impacts of catastrophic events: CGE analysis of resource loss and behavioral effects of an RDD attack scenario.

2012-04-01

We investigate the regional economic consequences of a hypothetical catastrophic event-attack via radiological dispersal device (RDD)-centered on the downtown Los Angeles area. We distinguish two routes via which such an event might affect regional economic activity: (i) reduction in effective resource supply (the resource loss effect) and (ii) shifts in the perceptions of economic agents (the behavioral effect). The resource loss effect relates to the physical destructiveness of the event, while the behavioral effect relates to changes in fear and risk perception. Both affect the size of the regional economy. RDD detonation causes little capital damage and few casualties, but generates substantial short-run resource loss via business interruption. Changes in fear and risk perception increase the supply cost of resources to the affected region, while simultaneously reducing demand for goods produced in the region. We use results from a nationwide survey, tailored to our RDD scenario, to inform our model values for behavioral effects. Survey results, supplemented by findings from previous research on stigmatized asset values, suggest that in the region affected by the RDD, households may require higher wages, investors may require higher returns, and customers may require price discounts. We show that because behavioral effects may have lingering long-term deleterious impacts on both the supply-cost of resources to a region and willingness to pay for regional output, they can generate changes in regional gross domestic product (GDP) much greater than those generated by resource loss effects. Implications for policies that have the potential to mitigate these effects are discussed. © 2011 Society for Risk Analysis.

Leveraging finances for public health system improvement: results from the Turning Point initiative.

Reforming the public health infrastructure requires substantial system changes at the state level; state health agencies, however, often lack the resources and support for strategic planning and systemwide improvement. The Turning Point Initiative provided support for states to focus on large-scale system changes that resulted in increased funding for public health capacity and infrastructure development. Turning Point provides a test case for obtaining financial and institutional resources focused on systems change and infrastructure development-areas for which it has been historically difficult to obtain long-term support. The purpose of this exploratory, descriptive survey research was to enumerate the actual resources leveraged toward public health system improvement through the partnerships, planning, and implementation activities funded by the Robert Wood Johnson Foundation as a part of the Turning Point Initiative.

E-learning: controlling costs and increasing value.

Walsh, Kieran

2015-04-01

E-learning now accounts for a substantial proportion of medical education provision. This progress has required significant investment and this investment has in turn come under increasing scrutiny so that the costs of e-learning may be controlled and its returns maximised. There are multiple methods by which the costs of e-learning can be controlled and its returns maximised. This short paper reviews some of those methods that are likely to be most effective and that are likely to save costs without compromising quality. Methods might include accessing free or low-cost resources from elsewhere; create short learning resources that will work on multiple devices; using open source platforms to host content; using in-house faculty to create content; sharing resources between institutions; and promoting resources to ensure high usage. Whatever methods are used to control costs or increase value, it is most important to evaluate the impact of these methods.

Cognitive stimulation therapy is a non-pharmacological intervention for people with dementia. Its use has been associated with substantial improvements in cognition and quality of life in studies from high-income countries, equivalent to those achieved by pharmacological treatments. Cognitive stimulation therapy may be particularly suited to low resource settings, such as sub-Saharan Africa, because it requires little specialist equipment and can be delivered by non-specialist health workers. The aim of this study was to adapt cognitive stimulation therapy for use in sub-Saharan Africa taking into account socio-cultural differences and resource implications. Cognitive stimulation therapy is a structured programme, originally developed in the United Kingdom. Substantial adaptations were required for use in sub-Saharan Africa. The formative method for adapting psychotherapy was used as a framework for the adaption process. The feasibility of using the adapted cognitive stimulation therapy programme to manage dementia was assessed in Tanzania and Nigeria in November 2013. Further adaptations were made following critical appraisal of feasibility. The adapted cognitive stimulation therapy intervention appeared feasible and acceptable to participants and carers. Key adaptations included identification of suitable treatment settings, task adaptation to accommodate illiteracy and uncorrected sensory impairment, awareness of cultural differences and usage of locally available materials and equipment to ensure sustainability. Cognitive stimulation therapy was successfully adapted for use in sub-Saharan Africa. Future work will focus on a trial of cognitive stimulation therapy in each setting. © The Author(s) 2016.

Advanced access: reducing waiting and delays in primary care.

PubMed

Murray, Mark; Berwick, Donald M

2003-02-26

Delay of care is a persistent and undesirable feature of current health care systems. Although delay seems to be inevitable and linked to resource limitations, it often is neither. Rather, it is usually the result of unplanned, irrational scheduling and resource allocation. Application of queuing theory and principles of industrial engineering, adapted appropriately to clinical settings, can reduce delay substantially, even in small practices, without requiring additional resources. One model, sometimes referred to as advanced access, has increasingly been shown to reduce waiting times in primary care. The core principle of advanced access is that patients calling to schedule a physician visit are offered an appointment the same day. Advanced access is not sustainable if patient demand for appointments is permanently greater than physician capacity to offer appointments. Six elements of advanced access are important in its application balancing supply and demand, reducing backlog, reducing the variety of appointment types, developing contingency plans for unusual circumstances, working to adjust demand profiles, and increasing the availability of bottleneck resources. Although these principles are powerful, they are counter to deeply held beliefs and established practices in health care organizations. Adopting these principles requires strong leadership investment and support.

Emergency nurses have a key role in managing the large numbers of patients that attend Australian emergency departments (EDs) annually, and require adequate educational preparation to deliver safe and quality patient care. This paper provides a detailed profile of nursing resources in Australian EDs, including ED locations, annual patient attendances, nurse staffing including level of education, and educational resources. Data were collected via online surveys of emergency Nurse Unit Managers and Nurse Educators and the MyHospitals website. Data were analysed by hospital peer group and state or territory. Comparisons were made using the Kruskal-Wallis Test and Spearman Rank Order Correlation. In 2011-2012, there were a median of 36,274 patient attendances to each of the 118 EDs sampled (IQR 28,279-46,288). Most of the nurses working in EDs were Registered Nurses (95.2%). Organisations provided educational resources including Clinical Nurse Educators (80.6%), learning packages (86%) and facilitation of postgraduate study (98%), but resources, both human and educational varied substantially between states and territories. One-third of emergency nurses held a relevant postgraduate qualification (30%). There are important variations in the emergency nursing resources available between Australian states and territories. The high percentage of RNs in Australian EDs is a positive finding, however strategies to increase the percentage of nurses with relevant postgraduate qualifications are required.

Freeman, Val L.; Weisner, Robert C.

1984-01-01

The Maroon Bells-Snowmass Wilderness and Additions, located in western Colorado, was examined for mineral potential. Evidence of mineralization is widespread and numerous areas have either probable or substantiated mineral-resource potential for one or more of the following metals: gold, silver, lead, zinc, copper, and molybdenum. In addition, part of the wilderness has substantiated coal resource potential. There is little promise for the occurrence of oil and gas or geothermal resources.

Issues and options in addressing the environmental consequences of livestock sector's growth.

Gerber, P J; Vellinga, T V; Steinfeld, H

2010-02-01

The growth of the livestock sector is being achieved at substantial environmental costs. Today, livestock are a major stressor of the global environmental, occupying a quarter of emerged land (including a third of arable land), contributing close to a fifth of the anthropogenic greenhouse gas emissions, using eight percent of all water resources and threatening a wide range of endangered species. At the same time, livestock are also a crucial engine of rural growth and a tool for improving food security. Policies are required to guide the sector in achieving sometimes conflicting development objectives. Potential pathways include encouraging resource use efficiency, correcting for environmental externalities and accelerating technological change.

Financing prevention: opportunities for economic analysis across the translational research cycle.

PubMed

Crowley, D Max; Jones, Damon

2016-03-01

Prevention advocates often make the case that preventive intervention not only improves public health and welfare but also can save public resources. Increasingly, evidence-based policy efforts considering prevention are focusing on how programs can save taxpayer resources from reduced burden on health, criminal justice, and social service systems. Evidence of prevention's return has begun to draw substantial investments from the public and private sector. Yet, translating prevention effectiveness into economic impact requires specific economic analyses to be employed across the stages of translational research. This work discusses the role of economic analysis in prevention science and presents key translational research opportunities to meet growing demand for estimates of prevention's economic and fiscal impact.

Mineral-resource studies of the Selway-Bitterroot Wilderness in Idaho County, Idaho, and Missoula and Ravalli Counties, Montana, were carried out. Four areas with probable and one small area of substantiated mineral-resource potential were recognized. The areas of the Running Creek, Painted Rocks, and Whistling Pig plutons of Tertiary age have probable resource potential for molybdenum, although detailed geochemical sampling and surface investigations failed to recognize mineralized systems at the surface. Randomly distributed breccia zones along a fault in the vicinity of the Cliff mine have a substantiated potential for small silver-copper-lead resources.

1984-01-01

A mineral-resource survey of the Boulder-Pioneer Wilderness study area in the Pioneer and Boulder Mountains of south-central Idaho, was made. The area has demonstrated resources of about 1. 7 million tons of lead-zinc-silver ore, mostly in the Phi Kappa mine, and an additional 2. 5 million tons of demonstrated resources in areas of substantiated potential for these metals and for tungsten, molybdenum, and fluorite. The survey indicates substantiated resource potential in eight areas and probable mineral-resource potential in seven. Mineral commodities of greatest intertest include tungsten, copper, lead, zinc, silver, gold, molybdenum, vanadium, and barite. There is little likelihood for the occurrence of oil, gas, coal, or geothermal resources.

To examine nursing time spent on administration of medications in a residential aged care (RAC) home, and to determine factors that influence the time to medicate a resident. Information on nursing time spent on medication administration is useful for planning and implementation of nursing resources. Nurses were observed over 12 morning medication rounds using a time-motion observational method and field notes, at two high-care units in an Australian RAC home. Nurses spent between 2.5 and 4.5 hours in a medication round. Administration of medication averaged 200 seconds per resident. Four factors had significant impact on medication time: number of types of medication, number of tablets taken by a resident, methods used by a nurse to prepare tablets and methods to provide tablets. Administration of medication consumed a substantial, though variable amount of time in the RAC home. Nursing managers need to consider the factors that influenced the nursing time required for the administration of medication in their estimation of nursing workload and required resources. To ensure safe medication administration for older people, managers should regularly assess the changes in the factors influencing nursing time on the administration of medication when estimating nursing workload and required resources. © 2015 John Wiley & Sons Ltd.

Parallel Processing of Images in Mobile Devices using BOINC

NASA Astrophysics Data System (ADS)

Curiel, Mariela; Calle, David F.; Santamaría, Alfredo S.; Suarez, David F.; Flórez, Leonardo

2018-04-01

Medical image processing helps health professionals make decisions for the diagnosis and treatment of patients. Since some algorithms for processing images require substantial amounts of resources, one could take advantage of distributed or parallel computing. A mobile grid can be an adequate computing infrastructure for this problem. A mobile grid is a grid that includes mobile devices as resource providers. In a previous step of this research, we selected BOINC as the infrastructure to build our mobile grid. However, parallel processing of images in mobile devices poses at least two important challenges: the execution of standard libraries for processing images and obtaining adequate performance when compared to desktop computers grids. By the time we started our research, the use of BOINC in mobile devices also involved two issues: a) the execution of programs in mobile devices required to modify the code to insert calls to the BOINC API, and b) the division of the image among the mobile devices as well as its merging required additional code in some BOINC components. This article presents answers to these four challenges.

Data sets for author name disambiguation: an empirical analysis and a new resource.

PubMed

Müller, Mark-Christoph; Reitz, Florian; Roy, Nicolas

2017-01-01

Data sets of publication meta data with manually disambiguated author names play an important role in current author name disambiguation (AND) research. We review the most important data sets used so far, and compare their respective advantages and shortcomings. From the results of this review, we derive a set of general requirements to future AND data sets. These include both trivial requirements, like absence of errors and preservation of author order, and more substantial ones, like full disambiguation and adequate representation of publications with a small number of authors and highly variable author names. On the basis of these requirements, we create and make publicly available a new AND data set, SCAD-zbMATH. Both the quantitative analysis of this data set and the results of our initial AND experiments with a naive baseline algorithm show the SCAD-zbMATH data set to be considerably different from existing ones. We consider it a useful new resource that will challenge the state of the art in AND and benefit the AND research community.

Knowledge base development requires a substantial investment in time, money, and resources in order to capture the knowledge and information necessary for anything other than trivial applications. This paper addresses a means to integrate the design and knowledge base development process through automated knowledge base development from CAD/CAE databases and files. Benefits of this approach include the development of a more efficient means of knowledge engineering, resulting in the timely creation of large knowledge based systems that are inherently free of error.

2016-01-01

Purpose Implementation of pharmacogenetics into clinical practice has been relatively slow despite substantial scientific progress over the last decade. One barrier that inhibits uptake of pharmacogenetics into routine clinical practice is the lack of knowledge of how to translate a genetic test into a clinical action based on current evidence. The purpose of this paper is to describe the current state of pharmacogenetic evidence and evidence-based resources that facilitate the uptake of pharmacogenetics into clinical practice. Summary Controversy exists over the required evidence threshold needed for routine clinical implementation of pharmacogenetics. Large randomized controlled trials are not clinically feasible or necessary for many pharmacogenetic applications. Online resources exist like the Clinical Pharmacogenetics Implementation Consortium (CPIC) and the Pharmacogenomics Knowledgebase (PharmGKB) that provide freely available, evidence-based resources that facilitate the translation of genetic laboratory test results into actionable prescribing recommendations for specific drugs. Conclusion Resources provided by organizations such as CPIC and PharmGKB that use standardized approaches to evaluate the literature and provide clinical guidance are essential for the implementation of pharmacogenetics into routine clinical practice.

Strategies for Energy Efficient Resource Management of Hybrid Programming Models

Li, Dong; Supinski, Bronis de; Schulz, Martin

2013-01-01

Many scientific applications are programmed using hybrid programming models that use both message-passing and shared-memory, due to the increasing prevalence of large-scale systems with multicore, multisocket nodes. Previous work has shown that energy efficiency can be improved using software-controlled execution schemes that consider both the programming model and the power-aware execution capabilities of the system. However, such approaches have focused on identifying optimal resource utilization for one programming model, either shared-memory or message-passing, in isolation. The potential solution space, thus the challenge, increases substantially when optimizing hybrid models since the possible resource configurations increase exponentially. Nonetheless, with the accelerating adoptionmore » of hybrid programming models, we increasingly need improved energy efficiency in hybrid parallel applications on large-scale systems. In this work, we present new software-controlled execution schemes that consider the effects of dynamic concurrency throttling (DCT) and dynamic voltage and frequency scaling (DVFS) in the context of hybrid programming models. Specifically, we present predictive models and novel algorithms based on statistical analysis that anticipate application power and time requirements under different concurrency and frequency configurations. We apply our models and methods to the NPB MZ benchmarks and selected applications from the ASC Sequoia codes. Overall, we achieve substantial energy savings (8.74% on average and up to 13.8%) with some performance gain (up to 7.5%) or negligible performance loss.« less

Effect of video server topology on contingency capacity requirements

NASA Astrophysics Data System (ADS)

Kienzle, Martin G.; Dan, Asit; Sitaram, Dinkar; Tetzlaff, William H.

1996-03-01

Video servers need to assign a fixed set of resources to each video stream in order to guarantee on-time delivery of the video data. If a server has insufficient resources to guarantee the delivery, it must reject the stream request rather than slowing down all existing streams. Large scale video servers are being built as clusters of smaller components, so as to be economical, scalable, and highly available. This paper uses a blocking model developed for telephone systems to evaluate video server cluster topologies. The goal is to achieve high utilization of the components and low per-stream cost combined with low blocking probability and high user satisfaction. The analysis shows substantial economies of scale achieved by larger server images. Simple distributed server architectures can result in partitioning of resources with low achievable resource utilization. By comparing achievable resource utilization of partitioned and monolithic servers, we quantify the cost of partitioning. Next, we present an architecture for a distributed server system that avoids resource partitioning and results in highly efficient server clusters. Finally, we show how, in these server clusters, further optimizations can be achieved through caching and batching of video streams.

Background The key aims of this study were to identify sources of support for cancer registry activities, to quantify resource use and estimate costs to operate registries in low- and middle-income countries (LMIC) at different stages of development across three continents. Methods Using the Centers for Disease Control and Prevention’s (CDC’s) International Registry Costing Tool (IntRegCosting Tool), cost and resource use data were collected from eight population-based cancer registries, including one in a low-income country (Uganda [Kampala)]), two in lower to middle-income countries (Kenya [Nairobi] and India [Mumbai]), and five in an upper to middle-income country (Colombia [Pasto, Barranquilla, Bucaramanga, Manizales and Cali cancer registries]). Results Host institution contributions accounted for 30%–70% of total investment in cancer registry activities. Cancer registration involves substantial fixed cost and labor. Labor accounts for more than 50% of all expenditures across all registries. The cost per cancer case registered in low-income and lower-middle-income countries ranged from US $3.77 to US $15.62 (United States dollars). In Colombia, an upper to middle-income country, the cost per case registered ranged from US $41.28 to US $113.39. Registries serving large populations (over 15 million inhabitants) had a lower cost per inhabitant (less than US $0.01 in Mumbai, India) than registries serving small populations (under 500,000 inhabitants) [US $0.22] in Pasto, Colombia. Conclusion This study estimates the total cost and resources used for cancer registration across several countries in the limited-resource setting, and provides cancer registration stakeholders and registries-with opportunities to identify cost savings and efficiency improvements. Our results suggest that cancer registration involve substantial fixed costs and labor, and that partnership with other institutions is critical for the operation and sustainability of cancer registries in limited resource settings. Although we included registries from a variety of limited-resource areas, information from eight registries in four countries may not be large enough to capture all the potential differences among the registries in limited-resource settings.

China is facing the challenge of feeding a growing population with the declining cropland and increasing shortage of water resources under the changing climate. This study identified that the opportunistic profit-driven shifts of planting areas and crop species composition have strongly reduced the food production capacity of China. First, the regional cultivation patterns of major crops in China have substantially shifted during the past five decades. Southeast and South China, the regions with abundant water resources and fewer natural disasters, have lost large planting areas of cropland in order to pursue industry and commerce. Meanwhile, Northeast and Northwest China, the regions with low water resources and frequent natural disasters, have witnessed increases in planting areas. These macroshifts have reduced the national food production by 1.02% per year. The lost grain production would have been enough to feed 13 million people. Second, the spatial shifts have been accompanied by major changes in crop species composition, with substantial increases in planting area and production of maize, due to its low water consumption and high economic returns. Consequently, the stockpile of maize in China has accounted for more than half of global stockpile, and the stock to use ratio of maize in China has exceeded the reliable level. Market-driven regional shifts of cropping practices have resulted in larger irrigation requirements and aggravated environmental stresses. Our results highlighted the need for Chinese food policies to consider the spatial shifts in cultivation, and the planting crop compositions limited by regional water resources and climate change.

Patients with multiple myeloma (MM) often experience debilitating skeletal-related events (SREs: pathologic fracture, radiation to bone [RB], surgery to bone [SB] or spinal cord compression [SCC]). This is the first comprehensive, prospective, observational analysis of healthcare resource utilisation (HRU), independently attributed to SREs by investigators, in patients with MM. Eligible patients had lytic bone lesions, life expectancy ≥6 months, Eastern Cooperative Oncology Group performance status ≤2 and ≥1 SRE in the 97 days before enrolment. Data were collected retrospectively for 97 days before enrolment and prospectively for 18-21 months. Altogether, 153 patients were enrolled from Germany, Italy, Spain and the United Kingdom. Of the 281 observed SREs, 36.7% required inpatient stays (mean duration: 20.6 days per SRE [standard deviation (SD): 22.9]). SB and SCC were the SREs most likely to require stays (72.3% and 50.0% of SREs, respectively); SCC required the longest mean (SD) stay per event (40.5 [40.8] days). Overall, 179 SREs required outpatient visits; this was most likely for RB (74.8%) and least likely for non-vertebral fracture (50.0%). All SREs were associated with substantial HRU; therefore, preventing SREs in MM will reduce the economic and resource burden on healthcare systems. © 2018 The Authors.

Reexamining Sample Size Requirements for Multivariate, Abundance-Based Community Research: When Resources are Limited, the Research Does Not Have to Be.

2015-01-01

Community ecologists commonly perform multivariate techniques (e.g., ordination, cluster analysis) to assess patterns and gradients of taxonomic variation. A critical requirement for a meaningful statistical analysis is accurate information on the taxa found within an ecological sample. However, oversampling (too many individuals counted per sample) also comes at a cost, particularly for ecological systems in which identification and quantification is substantially more resource consuming than the field expedition itself. In such systems, an increasingly larger sample size will eventually result in diminishing returns in improving any pattern or gradient revealed by the data, but will also lead to continually increasing costs. Here, we examine 396 datasets: 44 previously published and 352 created datasets. Using meta-analytic and simulation-based approaches, the research within the present paper seeks (1) to determine minimal sample sizes required to produce robust multivariate statistical results when conducting abundance-based, community ecology research. Furthermore, we seek (2) to determine the dataset parameters (i.e., evenness, number of taxa, number of samples) that require larger sample sizes, regardless of resource availability. We found that in the 44 previously published and the 220 created datasets with randomly chosen abundances, a conservative estimate of a sample size of 58 produced the same multivariate results as all larger sample sizes. However, this minimal number varies as a function of evenness, where increased evenness resulted in increased minimal sample sizes. Sample sizes as small as 58 individuals are sufficient for a broad range of multivariate abundance-based research. In cases when resource availability is the limiting factor for conducting a project (e.g., small university, time to conduct the research project), statistically viable results can still be obtained with less of an investment.

Prefrontal Cortical Inactivations Decrease Willingness to Expend Cognitive Effort on a Rodent Cost/Benefit Decision-Making Task.

PubMed

Hosking, Jay G; Cocker, Paul J; Winstanley, Catharine A

2016-04-01

Personal success often necessitates expending greater effort for greater reward but, equally important, also requires judicious use of our limited cognitive resources (e.g., attention). Previous animal models have shown that the prelimbic (PL) and infralimbic (IL) regions of the prefrontal cortex (PFC) are not involved in (physical) effort-based choice, whereas human studies have demonstrated PFC contributions to (mental) effort. Here, we utilize the rat Cognitive Effort Task (rCET) to probe PFC's role in effort-based decision making. In the rCET, animals can choose either an easy trial, where the attentional demand is low but the reward (sugar) is small or a difficult trial on which both the attentional demand and reward are greater. Temporary inactivation of PL and IL decreased all animals' willingness to expend mental effort and increased animals' distractibility; PL inactivations more substantially affected performance (i.e., attention), whereas IL inactivations increased motor impulsivity. These data imply that the PFC contributes to attentional resources, and when these resources are diminished, animals shift their choice (via other brain regions) accordingly. Thus, one novel therapeutic approach to deficits in effort expenditure may be to focus on the resources that such decision making requires, rather than the decision-making process per se. © The Author 2015.

1980-01-01

Construction and operation of a 60-unit (300 GW) domestic SPS over the period 2000 to 2030 would stress many segments of U.S. society. A significant commitment of resources (land, energy, materials) would be required, and a substantial proportion of them would have to be committed prior to the production of any SPS electricity. Forty-four concerns about the SPS were identified via a public outreach experiment involving 9000 individuals from three special interest organizations. The concerns focused on environmental impacts (particularly the effects of microwave radiation) and the centralizing tendency of the SPS on society.

Graveling, Alex J; Frier, Brian M

2009-08-01

Hypoglycaemia is a frequent side-effect of treatment with insulin and sulfonylureas for people with diabetes, threatening potentially serious morbidity and preventing optimal glycaemic control. Fear of hypoglycaemia and development of syndromes such as impaired awareness and counterregulatory deficiency provide additional hazards for intensification of treatment. Rapid lowering of HbA1c may be potentially dangerous in type 2 diabetes because of the adverse cardiovascular effects induced by hypoglycaemia. Hypoglycaemia can disrupt many everyday activities such as driving, work performance and recreational pursuits. Measures to reduce the risk of hypoglycaemia are labour-intensive and require substantial resources.

The results of a mineral-resource appraisal of the Birdseye, Nephi, And Santaquin Roadless Areas in Utah indicate several areas with probable or substantiated mineral-resource potential. The Eva mine in the Santaquin Roadless Area contains small, demonstrated resources of lead-zinc-silver ore. A probable resource potential for lead, zinc, and silver deposits exists in the area around the Eva mine, and elsewhere in the Birdseye, Nephi, and Santaquin Roadless Areas where Mississipian and Cambrian carbonate rocks occur. A substantiated potential for gypsum is recognized in the southwest corner of the Nephi Roadless Area and a probable resource potential in adjacent areas underlain by the Jurassic Arapien Shale. There are limestone resources for use in cement and smelter flux in the Nephi and Santaquin Roadless Areas, but similar limestone occurs abundantly outside the area. The potential for oil and gas resources cannot be assessed from available data. There are no indications of coal or geothermal resources in the roadless areas.

The purpose of this article is to set the context for this special issue of Disaster Medicine and Public Health Preparedness on the allocation of scarce resources in an improvised nuclear device incident. A nuclear detonation occurs when a sufficient amount of fissile material is brought suddenly together to reach critical mass and cause an explosion. Although the chance of a nuclear detonation is thought to be small, the consequences are potentially catastrophic, so planning for an effective medical response is necessary, albeit complex. A substantial nuclear detonation will result in physical effects and a great number of casualties that will require an organized medical response to save lives. With this type of incident, the demand for resources to treat casualties will far exceed what is available. To meet the goal of providing medical care (including symptomatic/palliative care) with fairness as the underlying ethical principle, planning for allocation of scarce resources among all involved sectors needs to be integrated and practiced. With thoughtful and realistic planning, the medical response in the chaotic environment may be made more effective and efficient for both victims and medical responders.

Requirements for Planetary Outpost Life-Support Systems and the Possible Use of In Situ Resources

If humans are ever to live and work on the Moon or Mars for extended periods of time, the operation of regenerative life-support systems at the planetary outposts will be a critical requirement. The substantial amount of materials consumed by humans and the inevitable waste products make open-loop life-support systems and resupply missions (as used in Space Shuttle and Mir operations) impractical and expensive. Natural resources found on the Moon and Mars could be used in conjunction with regenerative life support systems to further reduce the amount of material that would need to be delivered from Earth. There have been numerous studies and experiments conducted on the production of O from regolith materials on the Moon and from the atmosphere of Mars. One or several of these processes could undoubtedly be used to produce the O required by the crews at planetary outposts. Water is required in the greatest quantities, primarily for tasks such as personal hygiene and clothes washing, and it will be the most precious consumable. Again, several process have been described to produce water on the Moon using solar-wind implanted H and O, and if water ice can be found and mined at the lunar poles, another source of water may be available.

Best Practices Handbook for the Collection and Use of Solar Resource Data for Solar Energy Applications: Second Edition

As the world looks for low-carbon sources of energy, solar power stands out as the single most abundant energy resource on Earth. Harnessing this energy is the challenge for this century. Photovoltaics, solar heating and cooling, and concentrating solar power (CSP) are primary forms of energy applications using sunlight. These solar energy systems use different technologies, collect different fractions of the solar resource, and have different siting requirements and production capabilities. Reliable information about the solar resource is required for every solar energy application. This holds true for small installations on a rooftop as well as for large solar powermore » plants; however, solar resource information is of particular interest for large installations, because they require substantial investment, sometimes exceeding 1 billion dollars in construction costs. Before such a project is undertaken, the best possible information about the quality and reliability of the fuel source must be made available. That is, project developers need reliable data about the solar resource available at specific locations, including historic trends with seasonal, daily, hourly, and (preferably) subhourly variability to predict the daily and annual performance of a proposed power plant. Without this data, an accurate financial analysis is not possible. Additionally, with the deployment of large amounts of distributed photovoltaics, there is an urgent need to integrate this source of generation to ensure the reliability and stability of the grid. Forecasting generation from the various sources will allow for larger penetrations of these generation sources because utilities and system operators can then ensure stable grid operations. Developed by the foremost experts in the field who have come together under the umbrella of the International Energy Agency's Solar Heating and Cooling Task 46, this handbook summarizes state-of-the-art information about all the above topics.« less

Accelerated climate change and associated forest disturbances in the southwestern USA are anticipated to have substantial impacts on regional water resources. Few studies have quantified the impact of both climate change and land cover disturbances on water balances on the basin scale, and none on the regional scale. In this work, we evaluate the impacts of forest disturbances and climate change on a headwater basin to the Colorado River, the San Juan River watershed, using a robustly calibrated (Nash-Sutcliffe efficiency 0.76) hydrologic model run with updated formulations that improve estimates of evapotranspiration for semi-arid regions. Our results show that future disturbances will have a substantial impact on streamflow with implications for water resource management. Our findings are in contradiction with conventional thinking that forest disturbances reduce evapotranspiration and increase streamflow. In this study, annual average regional streamflow under the coupled climate-disturbance scenarios is at least 6-11 % lower than those scenarios accounting for climate change alone; for forested zones of the San Juan River basin, streamflow is 15-21 % lower. The monthly signals of altered streamflow point to an emergent streamflow pattern related to changes in forests of the disturbed systems. Exacerbated reductions of mean and low flows under disturbance scenarios indicate a high risk of low water availability for forested headwater systems of the Colorado River basin. These findings also indicate that explicit representation of land cover disturbances is required in modeling efforts that consider the impact of climate change on water resources.

The land value impacts of wetland restoration.

U.S. regulations require offsets for aquatic ecosystems damaged during land development, often through restoration of alternative resources. What effect does large-scale wetland and stream restoration have on surrounding land values? Restoration effects on real estate values have substantial implications for protecting resources, increasing tax base, and improving environmental policies. Our analysis focuses on the three-county Raleigh-Durham-Chapel Hill, North Carolina region, which has experienced rapid development and extensive aquatic ecological restoration (through the state's Ecosystem Enhancement Program [EEP]). Since restoration sites are not randomly distributed across space, we used a genetic algorithm to match parcels near restoration sites with comparable control parcels. Similar to propensity score analysis, this technique facilitates statistical comparison and isolates the effects of restoration sites on surrounding real estate values. Compared to parcels not proximate to any aquatic resources, we find that, 1) natural aquatic systems steadily and significantly increase parcel values up to 0.75 mi away, and 2) parcels <0.5 mi from EEP restoration sites have significantly lower sale prices, while 3) parcels >0.5 mi from EEP sites gain substantial amenity value. When we control for intervening water bodies (e.g. un-restored streams and wetlands), we find a similar inflection point whereby parcels <0.5 mi from EEP sites exhibit lower values, and sites 0.5-0.75 mi away exhibit increased values. Our work points to the need for higher public visibility of aquatic ecosystem restoration programs and increased public information about their value. Copyright © 2013 Elsevier Ltd.

The ecology of population dispersal: Modeling alternative basin-plateau foraging strategies to explain the Numic expansion.

The expansion of Numic speaking populations into the Great Basin required individuals to adapt to a relatively unproductive landscape. Researchers have proposed numerous social and subsistence strategies to explain how and why these settlers were able to replace any established populations, including private property and intensive plant processing. Here we evaluate these hypotheses and propose a new strategy involving the use of landscape fire to increase resource encounter rates. Implementing a novel, spatially explicit, multi-scalar prey choice model, we examine how individual decisions approximating each alternative strategy (private property, anthropogenic fire, and intensive plant processing) would aggregate at the patch and band level to confer an overall benefit to this colonizing population. Analysis relies on experimental data reporting resource profitability and abundance, ecological data on the historic distribution of vegetation patches, and ethnohistoric data on the distribution of Numic bands. Model results show that while resource privatization and landscape fires produce a substantial advantage, intensified plant processing garners the greatest benefit. The relative benefits of alternative strategies vary significantly across ecological patches resulting in variation across ethnographic band ranges. Combined, a Numic strategy including all three alternatives would substantially increase subsistence yields. The application of a strategy set that includes landscape fire, privatization and intensified processing of seeds and nuts, explains why the Numa were able to outcompete local populations. This approach provides a framework to help explain how individual decisions can result in such population replacement events throughout human history. © 2017 Wiley Periodicals, Inc.

Academic program models for undergraduate biomedical engineering.

Krishnan, Shankar M

2014-01-01

There is a proliferation of medical devices across the globe for the diagnosis and therapy of diseases. Biomedical engineering (BME) plays a significant role in healthcare and advancing medical technologies thus creating a substantial demand for biomedical engineers at undergraduate and graduate levels. There has been a surge in undergraduate programs due to increasing demands from the biomedical industries to cover many of their segments from bench to bedside. With the requirement of multidisciplinary training within allottable duration, it is indeed a challenge to design a comprehensive standardized undergraduate BME program to suit the needs of educators across the globe. This paper's objective is to describe three major models of undergraduate BME programs and their curricular requirements, with relevant recommendations to be applicable in institutions of higher education located in varied resource settings. Model 1 is based on programs to be offered in large research-intensive universities with multiple focus areas. The focus areas depend on the institution's research expertise and training mission. Model 2 has basic segments similar to those of Model 1, but the focus areas are limited due to resource constraints. In this model, co-op/internship in hospitals or medical companies is included which prepares the graduates for the work place. In Model 3, students are trained to earn an Associate Degree in the initial two years and they are trained for two more years to be BME's or BME Technologists. This model is well suited for the resource-poor countries. All three models must be designed to meet applicable accreditation requirements. The challenges in designing undergraduate BME programs include manpower, facility and funding resource requirements and time constraints. Each academic institution has to carefully analyze its short term and long term requirements. In conclusion, three models for BME programs are described based on large universities, colleges, and community colleges. Model 1 is suitable for research-intensive universities. Models 2 and 3 can be successfully implemented in higher education institutions with low and limited resources with appropriate guidance and support from international organizations. The models will continually evolve mainly to meet the industry needs.

A model to forecast data centre infrastructure costs.

Vernet, R.

2015-12-01

The computing needs in the HEP community are increasing steadily, but the current funding situation in many countries is tight. As a consequence experiments, data centres, and funding agencies have to rationalize resource usage and expenditures. CC-IN2P3 (Lyon, France) provides computing resources to many experiments including LHC, and is a major partner for astroparticle projects like LSST, CTA or Euclid. The financial cost to accommodate all these experiments is substantial and has to be planned well in advance for funding and strategic reasons. In that perspective, leveraging infrastructure expenses, electric power cost and hardware performance observed in our site over the last years, we have built a model that integrates these data and provides estimates of the investments that would be required to cater to the experiments for the mid-term future. We present how our model is built and the expenditure forecast it produces, taking into account the experiment roadmaps. We also examine the resource growth predicted by our model over the next years assuming a flat-budget scenario.

Mobilization strategy to overcome global crisis of water consumption

Suzdaleva, Antonina; Goryunova, Svetlana; Marchuk, Aleksey; Borovkov, Valery

2017-10-01

Today, the global water consumption crisis is one of the main threats that can disrupt socio-economic and environmental conditions of life of the majority of the world’s population. The water consumption mobilization strategy is based on the idea of increasing the available water resources. The main direction for the implementation of this strategy is the construction of anti-rivers - the systems for inter-basin (interregional) water resources redistribution. Antirivers are intended for controlled redistribution of water resources from regions with their catastrophic excess to regions with their critical shortage. The creation of anti-rivers, taking into account the requirements of environmental safety, will form large-scale managed natural- engineering systems and implement the principle of sustainable development adopted by the United Nations. The aim of the article is to substantiate a new methodological approach to address the problem, where the implementation of this approach can prevent large-scale humanitarian and environmental disasters expected in the coming years.

Today there are significant challenges to public health, and effective responses to them will require complex approaches and strategies implemented by a qualified workforce. An adequately prepared workforce requires long-term development; however, local health departments have limited financial and staff resources. Schools and programs accredited by the Council for Education on Public Health (CEPH) are required to provide continuing education but are constrained by the lack of resources, limited time, and geography. To meet these challenges, a statewide university/community collaborative model for delivering continuing education programs was developed. A needs assessment of California's public health workforce was conducted to identify areas of interest, and two continuing education trainings were developed and implemented using innovative distance education technology. Thirty-six percent of the participants completed electronic evaluations of learning outcomes and use of the digital technology platform. Participants indicated a significant increase in knowledge, reported that the trainings were cost effective and convenient, and said that they would participate in future online trainings. Collaborative partners found that this model provides a cost-effective, environmentally sound, and institutionally sustainable method for providing continuing education to public health professionals. Offering continuing education via distance technology requires substantial institutional infrastructure and resources that are often beyond what many public institutions can provide alone. This project provides a model for collaborating with community partners to provide trainings, using a digital technology platform that requires minimal training and allows presenters and participants to log on from anywhere there is Internet access.

Brown, Richard B.; Smoot, James C.; Underwood, Lauren; Armstrong, C. Duane

2012-01-01

Geospatial resource assessments frequently require timely geospatial data processing that involves large multivariate remote sensing data sets. In particular, for disasters, response requires rapid access to large data volumes, substantial storage space and high performance processing capability. The processing and distribution of this data into usable information products requires a processing pipeline that can efficiently manage the required storage, computing utilities, and data handling requirements. In recent years, with the availability of cloud computing technology, cloud processing platforms have made available a powerful new computing infrastructure resource that can meet this need. To assess the utility of this resource, this project investigates cloud computing platforms for bulk, automated geoprocessing capabilities with respect to data handling and application development requirements. This presentation is of work being conducted by Applied Sciences Program Office at NASA-Stennis Space Center. A prototypical set of image manipulation and transformation processes that incorporate sample Unmanned Airborne System data were developed to create value-added products and tested for implementation on the "cloud". This project outlines the steps involved in creating and testing of open source software developed process code on a local prototype platform, and then transitioning this code with associated environment requirements into an analogous, but memory and processor enhanced cloud platform. A data processing cloud was used to store both standard digital camera panchromatic and multi-band image data, which were subsequently subjected to standard image processing functions such as NDVI (Normalized Difference Vegetation Index), NDMI (Normalized Difference Moisture Index), band stacking, reprojection, and other similar type data processes. Cloud infrastructure service providers were evaluated by taking these locally tested processing functions, and then applying them to a given cloud-enabled infrastructure to assesses and compare environment setup options and enabled technologies. This project reviews findings that were observed when cloud platforms were evaluated for bulk geoprocessing capabilities based on data handling and application development requirements.

The Beartooth area comprises about 600 sq mi in the central part of the Beartooth Mountains in South-central Montana and northwestern Wyoming just northeast of Yellowstone National Park. A mineral-resource survey concluded that one area of probable and one of substantiated mineral-resource potential are present in the Beartooth area. Three small mining districts (Red Lodge, Stillwater, and Independence) and one possibly major district (Cooke City) adjoin the Beartooth area but lie almost entirely outside it; the northern part of the Cooke City mining district, around Goose Lake, is within the area. This area has substantiated resource potential for copper, silver, gold, and platinum-group elements. The Red Lodge mining district extends into the eastern part of the area and has a probable chrome resource potential. There is little promise for the discovery of energy resources in the area.

Mineral surveys of the Granite Fiords Wilderness study area revealed areas with probable and substantiated mineral-resource potential. In the northeastern sector, areas of probable and substantiated resource potential for gold, sivler, and base metals in small, locally high grade vein and disseminated deposits occur in recrystallized Mesozoic volcanic, sedimentary, and intrusive rocks. In the central part, areas of probable resource potential for gold, silver, copper, and zinc in disseminated and locally massive sulfide deposits occur in undated pelitic paragneiss roof pendants. A molybdenite-bearing quartz vein has been prospected in western Granite Fiords, and molybdenum also occurs along with other metals in veins in the northeastern sector and in geochemical samples collected from areas where there is probable resource potential for low-grade porphyry molybdenum deposits in several Cenozoic plutons. No energy resource potential was identified in the course of this study.

Feeding nine billion people sustainably: conserving land and water through shifting diets and changes in technologies.

PubMed

Springer, Nathaniel P; Duchin, Faye

2014-04-15

In the early 21st century the extensive clearing of forestland, fresh water scarcity, and sharp rises in the price of food have become causes for concern. These concerns may be substantially exacerbated over the next few decades by the need to provide improved diets for a growing global population. This study applies an inter-regional input-output model of the world economy, the World Trade Model, for analysis of alternative scenarios about satisfying future food requirements by midcentury. The scenario analysis indicates that relying only on more extensive use of arable land and fresh water would require clearing forests and exacerbating regional water scarcities. However, a combination of less resource-intensive diets and improved agricultural productivity, the latter especially in Africa, could make it possible to use these resources sustainably while also constraining increases in food prices. Unlike the scenario outcomes from other kinds of economic models, our framework reveals the potential for a decisive shift of production and export of agricultural products away from developed countries toward Africa and Latin America. Although the assumed changes in diets and technologies may not be realizable without incentives, our results suggest that these regions exhibit comparative advantages in agricultural production due to their large remaining resource endowments and their potential for higher yields.

Distribution Management System (DMS) applications require a substantial commitment of technical and financial resources. In order to proceed beyond limited-scale demonstration projects, utilities must have a clear understanding of the business case for committing these resources that recognizes the total cost of ownership. Many of the benefits provided by investments in DMSs do not translate easily into monetary terms, making cost-benefit calculations difficult. For example, Fault Location Isolation and Service Restoration (FLISR) can significantly reduce customer outage duration and improve reliability. However, there is no well-established and universally-accepted procedure for converting these benefits into monetary terms that can be comparedmore » directly to investment costs. This report presents a methodology to analyze the benefits and costs of DMS applications as fundamental to the business case.« less

The HIV care continuum: no partial credit given.

2012-09-10

Despite significant scale-up of HIV care and treatment across the world, overall effectiveness of HIV programs is severely undermined by attrition of patients across the HIV care continuum, both in resource-rich and resource-limited settings. The care continuum has four essential steps: linkage from testing to enrollment in care, determination of antiretroviral therapy (ART) eligibility, ART initiation, and adherence to medications to achieve viral suppression. In order to substantially improve health outcomes for the individual and potentially for prevention of transmission to others, each of the steps of the entire care continuum must be achieved. This will require the adoption of interventions that address the multiplicity of barriers and social contexts faced by individuals and populations across each step, a reconceptualization of services to maximize engagement in care, and ambitious evaluation of program performance using all-or-none measurement.

Defining lactation acuity to improve patient safety and outcomes.

PubMed

Mannel, Rebecca

2011-05-01

While substantial evidence exists identifying risks factors associated with premature weaning from breastfeeding, there are no previously published definitions of patient acuity in the lactation field. This article defines evidence-based levels of lactation acuity based on maternal and infant characteristics. Patient acuity, matching severity of illness to intensity of care required, is an important determinant of patient safety and outcomes. It is often used as part of a patient classification system to determine staffing needs and acceptable workloads in health care settings. As acuity increases, more resources, including more skilled clinicians, are needed to provide optimal care. Developing an evidence-based definition of lactation acuity can help to standardize terminology, more effectively distribute health care staff resources, encourage research to verify the validity and reliability of lactation acuity, and potentially improve breastfeeding initiation and duration rates.

With rapid recent advances in quantum technology, we are close to the threshold of quantum devices whose computational powers can exceed those of classical supercomputers. Here, we show that a quantum computer can be used to elucidate reaction mechanisms in complex chemical systems, using the open problem of biological nitrogen fixation in nitrogenase as an example. We discuss how quantum computers can augment classical computer simulations used to probe these reaction mechanisms, to significantly increase their accuracy and enable hitherto intractable simulations. Our resource estimates show that, even when taking into account the substantial overhead of quantum error correction, and the need to compile into discrete gate sets, the necessary computations can be performed in reasonable time on small quantum computers. Our results demonstrate that quantum computers will be able to tackle important problems in chemistry without requiring exorbitant resources.

Intervention complexity--a conceptual framework to inform priority-setting in health.

2005-01-01

Health interventions vary substantially in the degree of effort required to implement them. To some extent this is apparent in their financial cost, but the nature and availability of non-financial resources is often of similar importance. In particular, human resource requirements are frequently a major constraint. We propose a conceptual framework for the analysis of interventions according to their degree of technical complexity; this complements the notion of institutional capacity in considering the feasibility of implementing an intervention. Interventions are categorized into four dimensions: characteristics of the basic intervention; characteristics of delivery; requirements on government capacity; and usage characteristics. The analysis of intervention complexity should lead to a better understanding of supply- and demand-side constraints to scaling up, indicate priorities for further research and development, and can point to potential areas for improvement of specific aspects of each intervention to close the gap between the complexity of an intervention and the capacity to implement it. The framework is illustrated using the examples of scaling up condom social marketing programmes, and the DOTS strategy for tuberculosis control in highly resource-constrained countries. The framework could be used as a tool for policy-makers, planners and programme managers when considering the expansion of existing projects or the introduction of new interventions. Intervention complexity thus complements the considerations of burden of disease, cost-effectiveness, affordability and political feasibility in health policy decision-making. Reducing the technical complexity of interventions will be crucial to meeting the health-related Millennium Development Goals. PMID:15868020

For pipeline companies, mapping, facilities inventory, pipe inspections, environmental reporting, etc. is a monumental task. An Automated Mapping/Facilities Management/Geographic Information Systems (AM/FM/GIS) is the solution. However, this is costly and time consuming. James W. Sewall Company, an AM/FM/GIS consulting firm proposed an EOCAP project to Stennis Space Center (SSC) to develop a computerized system for storage and retrieval of digital aerial photography. This would provide its customer, Algonquin Gas Transmission Company, with an accurate inventory of rights-of-way locations and pipeline surroundings. The project took four years to complete and an important byproduct was SSC's Digital Aerial Rights-of-Way Monitoring System (DARMS). DARMS saves substantial time and money. EOCAP enabled Sewall to develop new products and expand its customer base. Algonquin now manages regulatory requirements more efficiently and accurately. EOCAP provides government co-funding to encourage private investment in and broader use of NASA remote sensing technology. Because changes on Earth's surface are accelerating, planners and resource managers must assess the consequences of change as quickly and accurately as possible. Pacific Meridian Resources and NASA's Stennis Space Center (SSC) developed a system for monitoring changes in land cover and use, which incorporated the latest change detection technologies. The goal of this EOCAP project was to tailor existing technologies to a system that could be commercialized. Landsat imagery enabled Pacific Meridian to identify areas that had sustained substantial vegetation loss. The project was successful and Pacific Meridian's annual revenues have substantially increased. EOCAP provides government co-funding to encourage private investment in and broader use of NASA remote sensing technology.

The ‘visibility’ of unpaid care in England

King, Derek; Knapp, Martin

2015-01-01

Summary Social work practice is increasingly concerned with support not just for service users but also for unpaid carers. A key aspect of practice is the assessment of carers’ needs. The Government has recently passed legislation that will widen eligibility for carers’ assessments and remove the requirement that carers must be providing a substantial amount of care on a regular basis. This article examines which carers are currently ‘visible’ or known to councils and which are not, and uses the results to examine the likely effects of the new legislation. In order to identify the characteristics of carers known to councils, the article uses large-scale surveys, comparing the 2009/10 Personal Social Services Survey of Adult Carers in England and the 2009/10 Survey of Carers in Households in England. Findings Carers who are known to councils provide extremely long hours of care. Among carers providing substantial care who are known to councils, the majority care for 100 or more hours a week. The focus of councils on carers providing long hours of care is associated with a number of other carer characteristics, such as poor health. Applications Councils' emphasis on the most intense carers is unlikely to be attributable solely to the current legislation. Therefore, dropping the substantial and regular clauses alone will not necessarily broaden access to carers' assessments and, in order to achieve this, considerable new resources may be needed. How far these resources are available will determine the extent to which practitioners can broaden access to carers' assessments. PMID:27182201

The rise of human populations and the growth of cities contribute to the depletion of natural resources, increase their cost, and create potential climatic changes. To overcome difficulties in supplying populations and reducing the resource cost, a search for alternative pharmaceutical, nanotechnology, and energy sources has begun. Among the alternative sources, microalgae are the most promising because they use carbon dioxide (CO2) to produce biomass and/or valuable compounds. Once produced, the biomass is ordinarily harvested and processed (downstream program). Drying, grinding, and extraction steps are destructive to the microalgal biomass that then needs to be renewed. The extraction and purification processes generate organic wastes and require substantial energy inputs. Altogether, it is urgent to develop alternative downstream processes. Among the possibilities, milking invokes the concept that the extraction should not kill the algal cells. Therefore, it does not require growing the algae anew. In this review, we discuss research on milking of diatoms. The main themes are (a) development of alternative methods to extract and harvest high added value compounds; (b) design of photobioreactors; (c) biodiversity and (d) stress physiology, illustrated with original results dealing with oleaginous diatoms.

The Karkheh River Basin (KRB) in southwest Iran is a key region for agriculture and energy production. KRB has high human-induced water demand and suffers from low water productivity. The future of the KRB and its growth clearly relies on sustainable water resources and hence, requires a holistic, basin-wide management and monitoring of natural resources (water, soil, vegetation, livestock, etc.). The KRB has dry regions in which water scarcity is a major challenge. In this study, we investigate changes in the hydrology of the basin during the past three decades including human-induced alterations of the system. We evaluate climatic variability, agricultural water use, land cover change and agriculture production. In this reaserch, we have developed a simple indicator for quantifying human influence on the hydrologic cycle. The results show that KRB's hydrology is significantly dominated by human activities. The anthropogenic water demand has increased substantially caused by growth in agriculture industry. In fact, the main reason for water scarcity in the region appears to be due to the increased anthropogenic water demand resulting from substantial socio-economic growth in the past three decades. Our results show that continued growth in the region is not sustainable without considering major changes in water use efficiency, land cover management and water productivity.

Purpose of review Human brucellosis is a neglected, underrecognized infection of widespread geographic distribution. It causes acute febrile illness and a potentially debilitating chronic infection in humans, and livestock infection has substantial socioeconomic impact. This review describes new information regarding the epidemiology of brucellosis in the developing world and advances in diagnosis and treatment. Recent findings The highest recorded incidence of human brucellosis occurs in the Middle East and Central Asia. Fever etiology studies demonstrate brucellosis as a cause of undifferentiated febrile illness in the developing world. Brucellosis is a rare cause of fever among returning travelers, but is more common among travelers returning from the Middle East and North Africa. Sensitive and specific rapid diagnostic tests appropriate for resource-limited settings have been validated. Randomized controlled trials demonstrate that optimal treatment for human brucellosis consists of doxycycline and an aminoglycoside. Decreasing the burden of human brucellosis requires control of animal brucellosis, but evidence to inform the design of control programs in the developing world is needed. Summary Brucellosis causes substantial morbidity in human and animal populations. While improvements in diagnostic options for resource-limited settings and stronger evidence for optimal therapy should enhance identification and treatment of human brucellosis, prevention of human disease through control in animals remains paramount.

2014-12-01

Cloud-based applications or apps are a promising medium through which water resources models and data can be conveyed in a user-friendly environment—making them more accessible to decision-makers and stakeholders. In the context of this work, a water resources web app is a web application that exposes limited modeling functionality for a scenario exploration activity in a structured workflow (e.g.: land use change runoff analysis, snowmelt runoff prediction, and flood potential analysis). The technical expertise required to develop water resources web apps can be a barrier to many potential developers of water resources apps. One challenge that developers face is in providing spatial storage, analysis, and visualization for the spatial data that is inherent to water resources models. The software projects that provide this functionality are non-standard to web development and there are a large number of free and open source software (FOSS) projects to choose from. In addition, it is often required to synthesize several software projects to provide all of the needed functionality. Another challenge for the developer will be orchestrating the use of several software components. Consequently, the initial software development investment required to deploy an effective water resources cloud-based application can be substantial. The Tethys Platform has been developed to lower the technical barrier and minimize the initial development investment that prohibits many scientists and engineers from making use of the web app medium. Tethys synthesizes several software projects including PostGIS for spatial storage, 52°North WPS for spatial analysis, GeoServer for spatial publishing, Google Earth™, Google Maps™ and OpenLayers for spatial visualization, and Highcharts for plotting tabular data. The software selection came after a literature review of software projects being used to create existing earth sciences web apps. All of the software is linked via a Python-powered software development kit (SDK). Tethys developers use the SDK to build their apps and incorporate the needed functionality from the software suite. The presentation will include several apps that have been developed using Tethys to demonstrate its capabilities.

Mineral surveys conducted in the Idaho Wilderness identified 28 areas with probable or substantiated mineral-resource potential, and 5 mines with demonstrated or inferred resources. Metals including gold, silver, copper, lead, zinc, and tungsten, have been extracted from deposits inside the wilderness. Current studies indicate additional areas of probable mineral-resource potential for gold, tungsten, mercury, rare-earth elements, and base metals related to intrusive rocks that follow structures formed by cauldron subsidence. These on-going studies also indicate that there is probable and substantiated resource potential for cobalt with copper, silver, and gold in the Precambrian rocks in the northeastern part of the wilderness in a geologic environment similar to that of the Blackbird mine that lies outside the area. The nature of the geologic terrane precludes the potential for organic fuels.

Principles of biorefineries.

Kamm, B; Kamm, M

2004-04-01

Sustainable economic growth requires safe, sustainable resources for industrial production. For the future re-arrangement of a substantial economy to biological raw materials, completely new approaches in research and development, production and economy are necessary. Biorefineries combine the necessary technologies between biological raw materials and industrial intermediates and final products. The principal goal in the development of biorefineries is defined by the following: (biomass) feedstock-mix + process-mix --> product-mix. Here, particularly the combination between biotechnological and chemical conversion of substances will play an important role. Currently the "whole-crop biorefinery", "green biorefinery" and "lignocellulose-feedstock biorefinery" systems are favored in research and development.

Transferring technology to the public sector.

Alper, M. E.

1972-01-01

Approximately four years ago the Jet Propulsion Laboratory, under NASA sponsorship, began to devote some of its resources to examining ways to transfer space technology to the civil sector. As experience accumulated under this program, certain principles basic to success in technology transfer became apparent. An adequate definition of each problem must be developed before any substantial effort is expended on a solution. In most instances, a source of funds other than the potential user is required to support the problem definition phase of the work. Sensitivity to the user's concerns and effective interpersonal communications between the user and technical personnel are essential to success.

Theories of Willpower Affect Sustained Learning

2012-01-01

Building cognitive abilities often requires sustained engagement with effortful tasks. We demonstrate that beliefs about willpower–whether willpower is viewed as a limited or non-limited resource–impact sustained learning on a strenuous mental task. As predicted, beliefs about willpower did not affect accuracy or improvement during the initial phases of learning; however, participants who were led to view willpower as non-limited showed greater sustained learning over the full duration of the task. These findings highlight the interactive nature of motivational and cognitive processes: motivational factors can substantially affect people’s ability to recruit their cognitive resources to sustain learning over time.

Childhood acute myeloid leukaemia (AML) requires intensive therapy and is associated with survival rates that are substantially inferior to many other childhood malignancies. We undertook a retrospective analysis of Australian Paediatric Cancer Registry data from 1997 to 2008 together with a single-centre audit during the same period assessing burden on service delivery at a tertiary children's hospital (Royal Children's Hospital, Brisbane). Although survival improved from 54.3% (1997-2002) to 69.2% (2003-2008), childhood AML caused a disproportionate number of childhood cancer deaths, accounting for 5.5% of all childhood cancer diagnoses yet 7.9% of all childhood cancer mortality. Furthermore, treatment was associated with significant toxicity requiring intensive use of local health resources. Novel therapeutic strategies aimed at improving survival and reducing toxicity are urgently required. © 2015 Wiley Periodicals, Inc.

Experimentally modeling stochastic processes with less memory by the use of a quantum processor

Palsson, Matthew S.; Gu, Mile; Ho, Joseph; Wiseman, Howard M.; Pryde, Geoff J.

2017-01-01

Computer simulation of observable phenomena is an indispensable tool for engineering new technology, understanding the natural world, and studying human society. However, the most interesting systems are often so complex that simulating their future behavior demands storing immense amounts of information regarding how they have behaved in the past. For increasingly complex systems, simulation becomes increasingly difficult and is ultimately constrained by resources such as computer memory. Recent theoretical work shows that quantum theory can reduce this memory requirement beyond ultimate classical limits, as measured by a process’ statistical complexity, C. We experimentally demonstrate this quantum advantage in simulating stochastic processes. Our quantum implementation observes a memory requirement of Cq = 0.05 ± 0.01, far below the ultimate classical limit of C = 1. Scaling up this technique would substantially reduce the memory required in simulations of more complex systems. PMID:28168218

Could the extensive use of rare elements in renewable energy technologies become a cause for concern?

2015-08-01

The energy transformation process beginning to take place in many countries as a response to climate change will reduce substantially the consumption of fossil fuels, but at the same time cause a large increase in the demand for other raw materials. Whereas it is difficult to estimate the quantities of, for example, iron, copper and aluminium required, the situation is somewhat simpler for the rare elements that might be needed in a sustainable energy economy based largely on photovoltaic sources, wind and possibly nuclear fusion. We consider briefly each of these technologies and discuss the supply risks associated with the rare elements required, if they were to be used in the quantities that might be required for a global energy transformation process. In passing, we point out the need in resource studies to define the terms "rare", "scarce" and "critical" and to use them in a consistent way.

2014-01-01

Background India has announced a goal of universal access to quality tuberculosis (TB) diagnosis and treatment. A number of novel diagnostics could help meet this important goal. The rollout of one such diagnostic, Xpert MTB/RIF (Xpert) is being considered, but if Xpert is used mainly for people with HIV or high risk of multidrug-resistant TB (MDR-TB) in the public sector, population-level impact may be limited. Methods and Findings We developed a model of TB transmission, care-seeking behavior, and diagnostic/treatment practices in India and explored the impact of six different rollout strategies. Providing Xpert to 40% of public-sector patients with HIV or prior TB treatment (similar to current national strategy) reduced TB incidence by 0.2% (95% uncertainty range [UR]: −1.4%, 1.7%) and MDR-TB incidence by 2.4% (95% UR: −5.2%, 9.1%) relative to existing practice but required 2,500 additional MDR-TB treatments and 60 four-module GeneXpert systems at maximum capacity. Further including 20% of unselected symptomatic individuals in the public sector required 700 systems and reduced incidence by 2.1% (95% UR: 0.5%, 3.9%); a similar approach involving qualified private providers (providers who have received at least some training in allopathic or non-allopathic medicine) reduced incidence by 6.0% (95% UR: 3.9%, 7.9%) with similar resource outlay, but only if high treatment success was assured. Engaging 20% of all private-sector providers (qualified and informal [providers with no formal medical training]) had the greatest impact (14.1% reduction, 95% UR: 10.6%, 16.9%), but required >2,200 systems and reliable treatment referral. Improving referrals from informal providers for smear-based diagnosis in the public sector (without Xpert rollout) had substantially greater impact (6.3% reduction) than Xpert scale-up within the public sector. These findings are subject to substantial uncertainty regarding private-sector treatment patterns, patient care-seeking behavior, symptoms, and infectiousness over time; these uncertainties should be addressed by future research. Conclusions The impact of new diagnostics for TB control in India depends on implementation within the complex, fragmented health-care system. Transformative strategies will require private/informal-sector engagement, adequate referral systems, improved treatment quality, and substantial resources.

Theoretical Calculations on the Feasibility of Microalgal Biofuels: Utilization of Marine Resources Could Help Realizing the Potential of Microalgae

2016-01-01

Abstract Microalgae have long been considered as one of most promising feedstocks with better characteristics for biofuels production over conventional energy crops. There have been a wide range of estimations on the feasibility of microalgal biofuels based on various productivity assumptions and data from different scales. The theoretical maximum algal biofuel productivity, however, can be calculated by the amount of solar irradiance and photosynthetic efficiency (PE), assuming other conditions are within the optimal range. Using the actual surface solar irradiance data around the world and PE of algal culture systems, maximum algal biomass and biofuel productivities were calculated, and feasibility of algal biofuel were assessed with the estimation. The results revealed that biofuel production would not easily meet the economic break‐even point and may not be sustainable at a large‐scale with the current algal biotechnology. Substantial reductions in the production cost, improvements in lipid productivity, recycling of resources, and utilization of non‐conventional resources will be necessary for feasible mass production of algal biofuel. Among the emerging technologies, cultivation of microalgae in the ocean shows great potentials to meet the resource requirements and economic feasibility in algal biofuel production by utilizing various marine resources.

Anthropogenic effects including river regulation, watershed development, contamination, and fish introductions have substantially affected the majority of freshwater habitats in Europe and North America. This pattern of resource development and degradation is widespread in the tropics, and often little is known about the resources before they are lost. This article describes the freshwater resources of Puerto Rico and identifies factors that threaten conservation of native fishes. The fishes found in freshwater habitats of Puerto Rico represent a moderately diverse assemblage composed of 14 orders, 29 families, and 82 species. There are fewer than 10 species of native peripherally-freshwater fish that require a link to marine systems. Introductions of nonindigenous species have greatly expanded fish diversity in freshwater systems, and native estuarine and marine species (18 families) also commonly enter lowland rivers and brackish lagoons. Environmental alterations, including land use and development, stream channelization, pollution, and the impoundment of rivers, combined with nonnative species introductions threaten the health and sustainability of aquatic resources in Puerto Rico. Six principal areas for attention that are important influences on the current and future status of the freshwater fish resources of Puerto Rico are identified and discussed.

Accelerated climate change and associated forest disturbances in the southwestern USA are anticipated to have substantial impacts on regional water resources. Few studies have quantified the impact of both climate change and land cover disturbances on water balances on the basin scale, and none on the regional scale. In this work, we evaluate the impacts of forest disturbances and climate change on a headwater basin to the Colorado River, the San Juan River watershed, using a robustly calibrated (Nash–Sutcliffe efficiency 0.76) hydrologic model run with updated formulations that improve estimates of evapotranspiration for semi-arid regions. Our results show that futuremore » disturbances will have a substantial impact on streamflow with implications for water resource management. Our findings are in contradiction with conventional thinking that forest disturbances reduce evapotranspiration and increase streamflow. In this study, annual average regional streamflow under the coupled climate–disturbance scenarios is at least 6–11 % lower than those scenarios accounting for climate change alone; for forested zones of the San Juan River basin, streamflow is 15–21 % lower. The monthly signals of altered streamflow point to an emergent streamflow pattern related to changes in forests of the disturbed systems. Exacerbated reductions of mean and low flows under disturbance scenarios indicate a high risk of low water availability for forested headwater systems of the Colorado River basin. Furthermore, these findings also indicate that explicit representation of land cover disturbances is required in modeling efforts that consider the impact of climate change on water resources.« less

Incorporation of Fixed Installation Costs into Optimization of Groundwater Remediation with a New Efficient Surrogate Nonlinear Mixed Integer Optimization Algorithm

NASA Astrophysics Data System (ADS)

Shoemaker, Christine; Wan, Ying

2016-04-01

Optimization of nonlinear water resources management issues which have a mixture of fixed (e.g. construction cost for a well) and variable (e.g. cost per gallon of water pumped) costs has been not well addressed because prior algorithms for the resulting nonlinear mixed integer problems have required many groundwater simulations (with different configurations of decision variable), especially when the solution space is multimodal. In particular heuristic methods like genetic algorithms have often been used in the water resources area, but they require so many groundwater simulations that only small systems have been solved. Hence there is a need to have a method that reduces the number of expensive groundwater simulations. A recently published algorithm for nonlinear mixed integer programming using surrogates was shown in this study to greatly reduce the computational effort for obtaining accurate answers to problems involving fixed costs for well construction as well as variable costs for pumping because of a substantial reduction in the number of groundwater simulations required to obtain an accurate answer. Results are presented for a US EPA hazardous waste site. The nonlinear mixed integer surrogate algorithm is general and can be used on other problems arising in hydrology with open source codes in Matlab and python ("pySOT" in Bitbucket).

Establishing Minimum Flow Requirements Based on Benthic Vegetation: What are Some Issues Related to Identifying Quantity of Inflow and Tools Used to Quantify Ecosystem Response?

NASA Astrophysics Data System (ADS)

Hunt, M. J.; Nuttle, W. K.; Cosby, B. J.; Marshall, F. E.

2005-05-01

Establishing minimum flow requirements in aquatic ecosystems is one way to stipulate controls on water withdrawals in a watershed. The basis of the determination is to identify the amount of flow needed to sustain a threshold ecological function. To develop minimum flow criteria an understanding of ecological response in relation to flow is essential. Several steps are needed including: (1) identification of important resources and ecological functions, (2) compilation of available information, (3) determination of historical conditions, (4) establishment of technical relationships between inflow and resources, and (5) identification of numeric criteria that reflect the threshold at which resources are harmed. The process is interdisciplinary requiring the integration of hydrologic and ecologic principles with quantitative assessments. The tools used quantify the ecological response and key questions related to how the quantity of flow influences the ecosystem are examined by comparing minimum flow determination in two different aquatic systems in South Florida. Each system is characterized by substantial hydrologic alteration. The first, the Caloosahatchee River is a riverine system, located on the southwest coast of Florida. The second, the Everglades- Florida Bay ecotone, is a wetland mangrove ecosystem, located on the southern tip of the Florida peninsula. In both cases freshwater submerged aquatic vegetation (Vallisneria americana or Ruppia maritima), located in areas of the saltwater- freshwater interface has been identified as a basis for minimum flow criteria. The integration of field studies, laboratory studies, and literature review was required. From this information we developed ecological modeling tools to quantify and predict plant growth in response to varying environmental variables. Coupled with hydrologic modeling tools questions relating to the quantity and timing of flow and ecological consequences in relation to normal variability are addressed.

Information needs of health technology assessment units and agencies in Spain.

2010-10-01

The aim of this study was to analyze the information needs of Spanish health technology assessment (HTA) agencies and units to facilitate access to the resources they require to substantiate their reports. A questionnaire was designed and distributed among HTA bodies to ascertain the actual situation of subscriptions to information resources and what information specialists from these bodies considered would be the ideal subscription situation. Their information needs were then studied, and the resources that best met these needs were put forward. Following this definition, a subscriptions policy was adopted with suppliers and publishers. The survey showed that HTA bodies share a minimum of core subscriptions that includes open sources (MEDLINE, DARE) and sources that the government subscribes to for the health community (ISI Web of Science, Cochrane Library Plus). There was no common approach to determining which databases to subscribe to (UpToDate, EMBASE, Ovid EBMR, CINAHL, or ECRI). After identifying the information needs, a list of resources was proposed that would best cover these needs and, of these, subscription to the following was proposed: Scopus, Ovid EBMR, Clinical Evidence, DynaMed, ECRI, and Hayes. There are differences in the way that HTA agencies and units access the different resources of biomedical information. Combined subscription to several resources for documentation services was suggested as a way of resolving these differences.

Money is arguably the most important resource derived from work and the most important source of stress for contemporary employees. A substantial body of research supports the relationship between access to financial resources and health and well-being, both at individual and aggregated (e.g. national) levels of analysis. Yet, surprisingly little occupational health psychology research has paid attention to financial issues experienced specifically by those in the labour force. With these issues in mind, the overarching goal of the present paper was to address conceptual and measurement issues in the study of objective and subjective aspects of financial stress and review several assessment options available to occupational health psychology researchers for both aspects of financial stress. Where appropriate, we offer guidance to researchers about choices among various financial stress measures and identify issues that require further research attention.

Opportunities and Challenges of Linking Scientific Core Samples to the Geoscience Data Ecosystem

NASA Astrophysics Data System (ADS)

Noren, A. J.

2016-12-01

Core samples generated in scientific drilling and coring are critical for the advancement of the Earth Sciences. The scientific themes enabled by analysis of these samples are diverse, and include plate tectonics, ocean circulation, Earth-life system interactions (paleoclimate, paleobiology, paleoanthropology), Critical Zone processes, geothermal systems, deep biosphere, and many others, and substantial resources are invested in their collection and analysis. Linking core samples to researchers, datasets, publications, and funding agencies through registration of globally unique identifiers such as International Geo Sample Numbers (IGSNs) offers great potential for advancing several frontiers. These include maximizing sample discoverability, access, reuse, and return on investment; a means for credit to researchers; and documentation of project outputs to funding agencies. Thousands of kilometers of core samples and billions of derivative subsamples have been generated through thousands of investigators' projects, yet the vast majority of these samples are curated at only a small number of facilities. These numbers, combined with the substantial similarity in sample types, make core samples a compelling target for IGSN implementation. However, differences between core sample communities and other geoscience disciplines continue to create barriers to implementation. Core samples involve parent-child relationships spanning 8 or more generations, an exponential increase in sample numbers between levels in the hierarchy, concepts related to depth/position in the sample, requirements for associating data derived from core scanning and lithologic description with data derived from subsample analysis, and publications based on tens of thousands of co-registered scan data points and thousands of analyses of subsamples. These characteristics require specialized resources for accurate and consistent assignment of IGSNs, and a community of practice to establish norms, workflows, and infrastructure to support implementation.

The video-based test of communication skills: description, development, and preliminary findings.

Mazor, Kathleen M; Haley, Heather-Lyn; Sullivan, Kate; Quirk, Mark E

2007-01-01

The importance of assessing physician-patient communication skills is widely recognized, but assessment methods are limited. Objective structured clinical examinations are time-consuming and resource intensive. For practicing physicians, patient surveys may be useful, but these also require substantial resources. Clearly, it would be advantageous to develop alternative or supplemental methods for assessing communication skills of medical students, residents, and physicians. The Video-based Test of Communication Skills (VTCS) is an innovative, computer-administered test, consisting of 20 very short video vignettes. In each vignette, a patient makes a statement or asks a question. The examinee responds verbally, as if it was a real encounter and he or she were the physician. Responses are recorded for later scoring. Test administration takes approximately 1 h. Generalizability studies were conducted, and scores for two groups of physicians predicted to differ in their communication skills were compared. Preliminary results are encouraging; the estimated g coefficient for the communication score for 20-vignette test (scored by five raters) is 0.79; g for the personal/affective score under the same conditions is 0.62. Differences between physicians were in the predicted direction, with physicians considered "at risk" for communication difficulties scoring lower than those not so identified. The VTCS is a short, portable test of communication skills. Results reported here suggest that scores reflect differences in skill levels and are generalizable. However, these findings are based on very small sample sizes and must be considered preliminary. Additional work is required before it will be possible to argue confidently that this test in particular, and this approach to testing communication skills in general, is valuable and likely to make a substantial contribution to assessment in medical education.

Evolution provides the unifying framework with which to understand biology. The coherent investigation of genic and genomic data often requires comparative genomics analyses based on whole-genome alignments, sets of homologous genes and other relevant datasets in order to evaluate and answer evolutionary-related questions.

SIERRA ANCHA WILDERNESS, ARIZONA.

USGS Publications Warehouse

Wrucke, Chester T.; Light, Thomas D.

1984-01-01

Mineral surveys show that the Sierra Ancha Wilderness in Arizona has demonstrated resources of uranium, asbestos, and iron; probable and substantiated resource potential for uranium, asbestos, and iron; and a probable resource potential for fluorspar. Uranium resources occur in vein and strata-bound deposits in siltstone that underlies much of the wilderness. Deposits of long-staple chrysotile asbestos are likely in parts of the wilderness adjacent to known areas of asbestos production. Magnetite deposits in the wilderness form a small iron resource. No fossil fuel resources were identified in this study.

Identifying improvement potentials in cement production with life cycle assessment.

PubMed

Boesch, Michael Elias; Hellweg, Stefanie

2010-12-01

Cement production is an environmentally relevant process responsible for 5% of total anthropogenic carbon dioxide emissions and 7% of industrial fuel use. In this study, life cycle assessment is used to evaluate improvement potentials in the cement production process in Europe and the USA. With a current fuel substitution rate of 18% in Europe and 11% in the USA, both regions have a substantial potential to reduce greenhouse gas emissions and save virgin resources by further increasing the coprocessing of waste fuels. Upgrading production technology would be particularly effective in the USA where many kiln systems with very low energy efficiency are still in operation. Using best available technology and a thermal substitution rate of 50% for fuels, greenhouse gas emissions could be reduced by 9% for Europe and 18% for the USA per tonne of cement. Since clinker production is the dominant pollution producing step in cement production, the substitution of clinker with mineral components such as ground granulated blast furnace slag or fly ash is an efficient measure to reduce the environmental impact. Blended cements exhibit substantially lower environmental footprints than Portland cement, even if the substitutes feature lower grindability and require additional drying and large transport distances. The highest savings in CO(2) emissions and resource consumption are achieved with a combination of measures in clinker production and cement blending.

Long-term costs often represent a large proportion of the total costs induced by stroke, but data on long-term poststroke resource use are sparse, especially regarding the trajectory of costs by severity. We used a multinational longitudinal survey to estimate patterns of poststroke resource use by degree of functional disability and to compare resource use between regions. The Survey of Health, Ageing and Retirement in Europe (SHARE) is a multinational database of adults 50 years and older, which includes demographic information about respondents, age when stroke first occurred, current activity of daily living (ADL) limitations, and health care resource use in the year before interview. We modeled resource use with a 2-part regression for number of hospital days, home nursing hours, and paid and unpaid home caregiving hours. After accounting for time since stroke, number of strokes and comorbidities, age, gender, and European regions, we found that poststroke resource use was strongly associated with ADL limitations. The duration since the stroke event was significantly associated only with inpatient care, and informal help showed significant regional heterogeneity across all ADL limitation levels. Poststroke physical deficits appear to be a strong driver of long-term resource utilization; treatments that decrease such deficits offer substantial potential for downline cost savings. Analyzing internationally comparable panel data, such as SHARE, provide valuable insight into long-term cost of stroke. More comprehensive international comparisons will require registries with follow-up, particularly for informal and formal home-based care. Copyright © 2015 National Stroke Association.

Adaptive subdomain modeling: A multi-analysis technique for ocean circulation models

NASA Astrophysics Data System (ADS)

Altuntas, Alper; Baugh, John

2017-07-01

Many coastal and ocean processes of interest operate over large temporal and geographical scales and require a substantial amount of computational resources, particularly when engineering design and failure scenarios are also considered. This study presents an adaptive multi-analysis technique that improves the efficiency of these computations when multiple alternatives are being simulated. The technique, called adaptive subdomain modeling, concurrently analyzes any number of child domains, with each instance corresponding to a unique design or failure scenario, in addition to a full-scale parent domain providing the boundary conditions for its children. To contain the altered hydrodynamics originating from the modifications, the spatial extent of each child domain is adaptively adjusted during runtime depending on the response of the model. The technique is incorporated in ADCIRC++, a re-implementation of the popular ADCIRC ocean circulation model with an updated software architecture designed to facilitate this adaptive behavior and to utilize concurrent executions of multiple domains. The results of our case studies confirm that the method substantially reduces computational effort while maintaining accuracy.

Changes in issues and advances in methodology have contributed to substantial progress in tree physiology research during the last several decades. Current research focuses on process interactions in complex systems and the integration of processes across multiple spatial and temporal scales. An increasingly important challenge for future research is assuring sustainability of production systems and forested ecosystems in the face of increased demands for natural resources and human disturbance of forests. Meeting this challenge requires significant shifts in research approach, including the study of limitations of productivity that may accompany achievement of system sustainability, and a focus on the biological capabilities of complex land bases altered by human activity.

Stream-based Hebbian eigenfilter for real-time neuronal spike discrimination

PubMed Central

2012-01-01

Background Principal component analysis (PCA) has been widely employed for automatic neuronal spike sorting. Calculating principal components (PCs) is computationally expensive, and requires complex numerical operations and large memory resources. Substantial hardware resources are therefore needed for hardware implementations of PCA. General Hebbian algorithm (GHA) has been proposed for calculating PCs of neuronal spikes in our previous work, which eliminates the needs of computationally expensive covariance analysis and eigenvalue decomposition in conventional PCA algorithms. However, large memory resources are still inherently required for storing a large volume of aligned spikes for training PCs. The large size memory will consume large hardware resources and contribute significant power dissipation, which make GHA difficult to be implemented in portable or implantable multi-channel recording micro-systems. Method In this paper, we present a new algorithm for PCA-based spike sorting based on GHA, namely stream-based Hebbian eigenfilter, which eliminates the inherent memory requirements of GHA while keeping the accuracy of spike sorting by utilizing the pseudo-stationarity of neuronal spikes. Because of the reduction of large hardware storage requirements, the proposed algorithm can lead to ultra-low hardware resources and power consumption of hardware implementations, which is critical for the future multi-channel micro-systems. Both clinical and synthetic neural recording data sets were employed for evaluating the accuracy of the stream-based Hebbian eigenfilter. The performance of spike sorting using stream-based eigenfilter and the computational complexity of the eigenfilter were rigorously evaluated and compared with conventional PCA algorithms. Field programmable logic arrays (FPGAs) were employed to implement the proposed algorithm, evaluate the hardware implementations and demonstrate the reduction in both power consumption and hardware memories achieved by the streaming computing Results and discussion Results demonstrate that the stream-based eigenfilter can achieve the same accuracy and is 10 times more computationally efficient when compared with conventional PCA algorithms. Hardware evaluations show that 90.3% logic resources, 95.1% power consumption and 86.8% computing latency can be reduced by the stream-based eigenfilter when compared with PCA hardware. By utilizing the streaming method, 92% memory resources and 67% power consumption can be saved when compared with the direct implementation of GHA. Conclusion Stream-based Hebbian eigenfilter presents a novel approach to enable real-time spike sorting with reduced computational complexity and hardware costs. This new design can be further utilized for multi-channel neuro-physiological experiments or chronic implants. PMID:22490725

Universal Blind Quantum Computation

NASA Astrophysics Data System (ADS)

Fitzsimons, Joseph; Kashefi, Elham

2012-02-01

Blind Quantum Computing (BQC) allows a client to have a server carry out a quantum computation for them such that the client's inputs, outputs and computation remain private. Recently we proposed a universal unconditionally secure BQC scheme, based on the conceptual framework of the measurement-based quantum computing model, where the client only needs to be able to prepare single qubits in separable states randomly chosen from a finite set and send them to the server, who has the balance of the required quantum computational resources. Here we present a refinement of the scheme which vastly expands the class of quantum circuits which can be directly implemented as a blind computation, by introducing a new class of resource states which we term dotted-complete graph states and expanding the set of single qubit states the client is required to prepare. These two modifications significantly simplify the overall protocol and remove the previously present restriction that only nearest-neighbor circuits could be implemented as blind computations directly. As an added benefit, the refined protocol admits a substantially more intuitive and simplified verification mechanism, allowing the correctness of a blind computation to be verified with arbitrarily small probability of error.

Aging and Attentional Control

2013-01-01

The research examines the structural bottleneck account and the resource account of the substantial dual-task deficits among older adults. Procedures from two common dual-task methodologies--the psychological refractory period and the relative-priority manipulation--were used to encourage maximization of the joint performance. Performance and time-sharing strategies from subjects between the ages of 20 and 70 were examined. Age-related declines in time-sharing efficiency and in the precision of the executive control process were observed. The age-related effect was larger when two manual responses were required than when one manual and one vocal response were required but no evidence for obligatory sequential processing was found. Except for the most demanding conditions, comparable practice effects were observed between the younger and older subjects, suggesting considerable cognitive plasticity in the older subjects. Implications for the two attentional accounts were discussed. PMID:23281799

Shared vision and autonomous motivation vs. financial incentives driving success in corporate acquisitions

PubMed Central

Clayton, Byron C.

2015-01-01

Successful corporate acquisitions require its managers to achieve substantial performance improvements in order to sufficiently cover acquisition premiums, the expected return of debt and equity investors, and the additional resources needed to capture synergies and accelerate growth. Acquirers understand that achieving the performance improvements necessary to cover these costs and create value for investors will most likely require a significant effort from mergers and acquisitions (M&A) management teams. This understanding drives the common and longstanding practice of offering hefty performance incentive packages to key managers, assuming that financial incentives will induce in-role and extra-role behaviors that drive organizational change and growth. The present study debunks the assumptions of this common M&A practice, providing quantitative evidence that shared vision and autonomous motivation are far more effective drivers of managerial performance than financial incentives.

Implementation uncertainty when using recreational hunting to manage carnivores

1. Wildlife managers often rely on resource users, such as recreational or commercial hunters, to achieve management goals. The use of hunters to control wildlife populations is especially common for predators and ungulates, but managers cannot assume that hunters will always fill annual quotas set by the authorities. It has been advocated that resource management models should account for uncertainty in how harvest rules are realized, requiring that this implementation uncertainty be estimated. 2. We used a survival analysis framework and long-term harvest data from large carnivore management systems in three countries (Estonia, Latvia and Norway) involving four species (brown bear, grey wolf, Eurasian lynx and wolverine) to estimate the performance of hunters with respect to harvest goals set by managers. 3. Variation in hunter quota-filling performance was substantial, ranging from 40% for wolverine in Norway to nearly 100% for lynx in Latvia. Seasonal and regional variation was also high within country–species pairs. We detected a positive relationship between the instantaneous potential to fill a quota slot and the relative availability of the target species for both wolverine and lynx in Norway. 4. Survivor curves and hazards – with survival time measured as the time from the start of a season until a quota slot is filled – can indicate the extent to which managers can influence harvest through adjustments of season duration and quota limits. 5. Synthesis and applications. We investigated seven systems where authorities use recreational hunting to manage large carnivore populations. The variation and magnitude of deviation from harvest goals was substantial, underlining the need to incorporate implementation uncertainty into resource management models and decisions-making. We illustrate how survival analysis can be used by managers to estimate the performance of resource users with respect to achieving harvest goals set by managers. The findings in this study come at an opportune time given the growing popularity of management strategy evaluation (MSE) models in fisheries and a push towards incorporating MSE into terrestrial harvest management.

Background Each year approximately 10 million babies do not breathe immediately at birth, of which about 6 million require basic neonatal resuscitation. The major burden is in low-income settings, where health system capacity to provide neonatal resuscitation is inadequate. Objective To systematically review the evidence for neonatal resuscitation content, training and competency, equipment and supplies, cost, and key program considerations, specifically for resource-constrained settings. Results Evidence from several observational studies shows that facility-based basic neonatal resuscitation may avert 30% of intrapartum-related neonatal deaths. Very few babies require advanced resuscitation (endotracheal intubation and drugs) and these newborns may not survive without ongoing ventilation; hence, advanced neonatal resuscitation is not a priority in settings without neonatal intensive care. Of the 60 million nonfacility births, most do not have access to resuscitation. Several trials have shown that a range of community health workers can perform neonatal resuscitation with an estimated effect of a 20% reduction in intrapartum-related neonatal deaths, based on expert opinion. Case studies illustrate key considerations for scale up. Conclusion Basic resuscitation would substantially reduce intrapartum-related neonatal deaths. Where births occur in facilities, it is a priority to ensure that all birth attendants are competent in resuscitation. Strategies to address the gap for home births are urgently required. More data are required to determine the impact of neonatal resuscitation, particularly on long-term outcomes in low-income settings. PMID:19815203

Detecting declines in the abundance of a bull trout (Salvelinus confluentus) population: Understanding the accuracy, precision, and costs of our efforts

Al-Chokhachy, R.; Budy, P.; Conner, M.

2009-01-01

Using empirical field data for bull trout (Salvelinus confluentus), we evaluated the trade-off between power and sampling effort-cost using Monte Carlo simulations of commonly collected mark-recapture-resight and count data, and we estimated the power to detect changes in abundance across different time intervals. We also evaluated the effects of monitoring different components of a population and stratification methods on the precision of each method. Our results illustrate substantial variability in the relative precision, cost, and information gained from each approach. While grouping estimates by age or stage class substantially increased the precision of estimates, spatial stratification of sampling units resulted in limited increases in precision. Although mark-resight methods allowed for estimates of abundance versus indices of abundance, our results suggest snorkel surveys may be a more affordable monitoring approach across large spatial scales. Detecting a 25% decline in abundance after 5 years was not possible, regardless of technique (power = 0.80), without high sampling effort (48% of study site). Detecting a 25% decline was possible after 15 years, but still required high sampling efforts. Our results suggest detecting moderate changes in abundance of freshwater salmonids requires considerable resource and temporal commitments and highlight the difficulties of using abundance measures for monitoring bull trout populations.

The role of nutrient reserves in mallard reproduction

USGS Publications Warehouse

Krapu, Gary L.

1981-01-01

Mallard (Anas platyrhynchos) populations breeding in temperate North America obtain a significant part of the energy and lipid requirements of reproduction at sites occupied prior to arrival on the breeding grounds. Protein for egg formation, however, is obtained principally from the diet during the nesting period. Both sexes arrive heavy and fat in North Dakota but experience substantial weight loss and lipid depletion during the nesting cycle. Weight loss is most pronounced among females and averages 25% from prelaying to late incubation. Body weights of both sexes are positively correlated with carcass lipid content. The paired male draws upon lipids early in the nesting season when an activity center is being established and defended and when females are preparing to nest. The female's lipid reserves are utilized primarily during laying and early incubation. The significance of lipid reserves diminishes as the nesting season progresses, and females do not acquire substantial lipid stores prior to renesting when the initial clutch is destroyed. The magnitude of lipid reserves carried in female carcasses is positively correlated with clutch size from mid-April to early June. Protein transfer for egg formation from flight and leg muscle and body organs can account for only a small part of the protein requirement for the clutch. By utilizing lipid reserves to meet energy requirements, the female can acquire sufficient protein from the diet to produce a large initial clutch even when foods are relatively scarce, whereas the renesting female must rely entirely upon food resources available at the breeding site for its nutrient and energy requirements.

Policy for material efficiency--sustainable taxation as a departure from the throwaway society.

PubMed

Stahel, Walter R

2013-03-13

The present economy is not sustainable with regard to its per capita material consumption. A dematerialization of the economy of industrialized countries can be achieved by a change in course, from an industrial economy built on throughput to a circular economy built on stock optimization, decoupling wealth and welfare from resource consumption while creating more work. The business models of a circular economy have been known since the mid-1970s and are now applied in a number of industrial sectors. This paper argues that a simple and convincing lever could accelerate the shift to a circular economy, and that this lever is the shift to a tax system based on the principles of sustainability: not taxing renewable resources including human labour--work--but taxing non-renewable resources instead is a powerful lever. Taxing materials and energies will promote low-carbon and low-resource solutions and a move towards a 'circular' regional economy as opposed to the 'linear' global economy requiring fuel-based transport for goods throughput. In addition to substantial improvements in material and energy efficiency, regional job creation and national greenhouse gas emission reductions, such a change will foster all activities based on 'caring', such as maintaining cultural heritage and natural wealth, health services, knowledge and know-how.

To describe perceived barriers and facilitators to implementing and sustaining Centering Pregnancy Plus (CP+) group prenatal care, 24 in-depth interviews were conducted with 22 clinicians, staff, administrators, and study personnel in six of the 14 sites of a randomized trial of the model. All sites served low-income, minority women. Sites for the present evaluation were selected for variation in location, study arm, and initial implementation response. Implementing CP+ was challenging in all sites, requiring substantial adaptations of clinical systems. All sites had barriers to meeting the model’s demands, but how sites responded to these barriers affected whether implementation thrived or struggled. Thriving sites had organizational cultures that supported innovation, champions who advocated for CP+, and staff who viewed logistical demands as manageable hurdles. Struggling sites had bureaucratic organizational structures and lacked buy-in and financial resources, and staff were overwhelmed by the model’s challenges. Findings suggested that implementing and sustaining health care innovation requires new practices and different ways of thinking, and health systems may not fully recognize the magnitude of change required. Consequently, evidence-based practices are modified or discontinued, and outcomes may differ from those in the original controlled studies. Before implementing new models of care, clinical settings should anticipate model demands and assess capacity for adapting to the disruptions of innovation. PMID:26340483

This study focuses on Active Flow Control methods used in conjunction with airplane high-lift systems. The project is motivated by the simplified high-lift system, which offers enhanced airplane performance compared to conventional high-lift systems. Computational simulations are used to guide the implementation of preferred flow control methods, which require a fluidic supply. It is first demonstrated that flow control applied to a high-lift configuration that consists of simple hinge flaps is capable of attaining the performance of the conventional high-lift counterpart. A set of flow control techniques has been subsequently considered to identify promising candidates, where the central requirement is that the mass flow for actuation has to be within available resources onboard. The flow control methods are based on constant blowing, fluidic oscillators, and traverse actuation. The simulations indicate that the traverse actuation offers a substantial reduction in required mass flow, and it is especially effective when the frequency of actuation is consistent with the characteristic time scale of the flow.

Getting Out of Orbit: Water Recycling Requirements and Technology Needs for Long Duration Missions Away from Earth

NASA Technical Reports Server (NTRS)

Barta, Daniel J.

2017-01-01

Deep-space crewed missions will not have regular access to the Earth's resources or the ability to rapidly return to Earth if a system fails. As crewed missions extend farther from Earth for longer periods, habitation systems must become more self-sufficient and reliable for safe, healthy, and sustainable human exploration. For human missions to Mars, Environmental Control and Life Support Systems (ECLSS) must be able operate for up to 1,100 days with minimal spares and consumables. These missions will require capabilities to more fully recycle atmospheric gases and wastewater to substantially reduce mission costs. Even with relatively austere requirements for use, water represents one of the largest consumables by mass. Systems must be available to extract and recycle water from all sources of waste. And given that there will be no opportunity to send samples back to Earth for analysis, analytical measurements will be limited to monitoring hardware brought on board the spacecraft. The Earth Reliant phase of NASA's exploration strategy includes leveraging the International Space Station (ISS) to demonstrate advanced capabilities for a robust and reliable ECLSS. The ISS Water Recovery System (WRS) includes a Urine Processor Assembly (UPA) for distillation and recovery of water from urine and a Water Processor Assembly (WPA) to process humidity condensate and urine distillate into potable water. Possible enhancements to more fully "close the water loop" include recovery of water from waste brines and solid wastes. A possible game changer is the recovery of water from local planetary resources through use of In Situ Resource Utilization (ISRU) technologies. As part of the development and demonstration sequence, NASA intends to utilize cis-Lunar space as a Proving Ground to verify systems for deep space habitation by conducting extended duration missions to validate our readiness for Mars.

Powering the planet: Chemical challenges in solar energy utilization

2006-01-01

Global energy consumption is projected to increase, even in the face of substantial declines in energy intensity, at least 2-fold by midcentury relative to the present because of population and economic growth. This demand could be met, in principle, from fossil energy resources, particularly coal. However, the cumulative nature of CO2 emissions in the atmosphere demands that holding atmospheric CO2 levels to even twice their preanthropogenic values by midcentury will require invention, development, and deployment of schemes for carbon-neutral energy production on a scale commensurate with, or larger than, the entire present-day energy supply from all sources combined. Among renewable energy resources, solar energy is by far the largest exploitable resource, providing more energy in 1 hour to the earth than all of the energy consumed by humans in an entire year. In view of the intermittency of insolation, if solar energy is to be a major primary energy source, it must be stored and dispatched on demand to the end user. An especially attractive approach is to store solar-converted energy in the form of chemical bonds, i.e., in a photosynthetic process at a year-round average efficiency significantly higher than current plants or algae, to reduce land-area requirements. Scientific challenges involved with this process include schemes to capture and convert solar energy and then store the energy in the form of chemical bonds, producing oxygen from water and a reduced fuel such as hydrogen, methane, methanol, or other hydrocarbon species.

A bottom-up approach to identifying the maximum operational adaptive capacity of water resource systems to a changing climate

Culley, S.; Noble, S.; Yates, A.; Timbs, M.; Westra, S.; Maier, H. R.; Giuliani, M.; Castelletti, A.

Many water resource systems have been designed assuming that the statistical characteristics of future inflows are similar to those of the historical record. This assumption is no longer valid due to large-scale changes in the global climate, potentially causing declines in water resource system performance, or even complete system failure. Upgrading system infrastructure to cope with climate change can require substantial financial outlay, so it might be preferable to optimize existing system performance when possible. This paper builds on decision scaling theory by proposing a bottom-up approach to designing optimal feedback control policies for a water system exposed to a changing climate. This approach not only describes optimal operational policies for a range of potential climatic changes but also enables an assessment of a system's upper limit of its operational adaptive capacity, beyond which upgrades to infrastructure become unavoidable. The approach is illustrated using the Lake Como system in Northern Italy—a regulated system with a complex relationship between climate and system performance. By optimizing system operation under different hydrometeorological states, it is shown that the system can continue to meet its minimum performance requirements for more than three times as many states as it can under current operations. Importantly, a single management policy, no matter how robust, cannot fully utilize existing infrastructure as effectively as an ensemble of flexible management policies that are updated as the climate changes.

Simulated patients (SPs) are often used in dietetics for the teaching and assessment of communication skills. The present study aimed to determine the impact of a SP encounter on communication skills in undergraduate preclinical dietetic students in the context of the resources required for delivering this educational strategy. This observational study collected assessment data from four cohorts of third-year dietetic students to examine the effect of participation in SP-embedded Objective Structured Clinical Exams. Students completed two SP interviews, 2 weeks apart, and communication skills were measured on both occasions. A subgroup of students received a video of their SP encounter. Differences between the two SP interview scores were compared to assess the impact of the SP encounter on communication skills. The required staff and resources were described. Data were collected involving 215 students. Out of 30 marks, there was a modest mean (SD) improvement in communication skills from the first to the second SP interview of 2.5 (4.2) (P < 0.01). There was an association between student ability and improvement in communication skills, with failing students demonstrating the greatest improvement between SP encounters. There were no observed benefits for the subset of students who received videos. Providing repeat SP interview opportunities results in only modest improvement in communication skills for most students. The use of SPs needs to be considered in context of the substantial costs and resources involved and tailored to student ability. © 2015 The British Dietetic Association Ltd.

To date, a substantial portion of multiple casualty incident literature has focused exclusively on prehospital and emergency department resources needed for optimal disaster response. Thus, inpatient resources required to care for individuals injured in multiple casualty events are not well described. To highlight the resources beyond initial emergency department triage needed for multiple casualty events, using one of the largest commercial aviation disasters in modern US history as a case study. Prospective case series of injured individuals treated at an urban level I trauma center following the crash of Asiana Airlines flight 214 on July 6, 2013. This analysis was conducted between June 1, 2014, and December 1, 2015. Commercial jetliner crash. Medical records, imaging data, nursing overtime, blood bank records, and trauma registry data were analyzed. Disaster logs, patient injuries, and blood product data were prospectively collected during the incident. Among 307 people aboard the flight, 192 were injured; 63 of the injured patients were initially evaluated at San Francisco General Hospital and Trauma Center (the highest number at any of the receiving medical facilities; age range, 4-74 years [23 were aged <17 years and 3 were aged >60 years]; median injury severity score of 19 admitted patients, 9 [range, 9-45]), including the highest number of critically injured patients (10 of 12). Despite the high impact of the crash, only 3 persons (<1%) died, including 1 in-hospital death. Among the 63 patients, 32 (50.8%) underwent a computed tomographic imaging study, with imaging of the abdomen and pelvis being the most common. Sixteen of the 32 patients undergoing computed tomography (50.0%) had a positive finding on at least 1 scan. Nineteen patients had major injuries and required admission, with 5 taken directly from the emergency department to the operating room. The most frequent injury was spinal fracture (13 patients). In the first 48 hours, 15 operations were performed and 117 total units of blood products were transfused. A total of 370 nursing overtime hours were required to treat the injured patients on the day of the event. Proper disaster preparedness requires attention to hospital-level needs beyond initial emergency department triage. The Asiana Airlines flight 214 crash highlights the need to plan for high use of advanced imaging, blood products, operating room availability, nursing resources, and management of inpatient hospital beds.

Assessment of differences in psychosocial resources and state of health of rural and urban residents--based on studies carried out on students during examination stress.

Civilization changes of the environment shaping the psychosocial resources from rural to urban influence human health. The study aimed to identify the differences due to the place of residence (rural, urban) as far as health resources are concerned (social support, sense of coherence, dehydroepiandrosterone sulfate concentration in plasma) and health in examination stress situations. The study also determined the concentration of dehydroepiandrosterone sulfate (health resource) and cortisol (stress indicator). The psychosocial variables were assessed using the scales: ISEL-48v. Coll., SOC-29, SF-36v.2™ o and analogue scale (perception of examination stress). The study included, based on a stratified sampling (year of study) and purposive sampling (written examination, major), 731 students representing the six universities in Lublin, south-east Poland. Among the respondents, 130 students were rural residents. Health resources of students living in rural and urban areas generally differ statistically significantly in social support and the subscales of availability of tangible support, availability of appreciative support, the availability of cognitive-evaluative support and a sense of resourcefulness. The study recorded a sstatistically significantly larger network of family ties among students living in rural areas. The demonstrated diversity of resources did not substantially affect the perceived health, with the exception of pain sensation. Examination stress assessed by subjective opinion of the respondents and plasma cortisol levels vary relative to the place of residence. Students residing in rural areas showed significantly lower cortisol levels values, but subjectively perceived the situation of examation as more stressful. Differences in health resources and their mechanism of impact on health, to a limited extent, were conditioned by the place of residence, but they are so important in the light of human choices that they require further analysis.

Challenges for Social Control in Wireless Mobile Grids

NASA Astrophysics Data System (ADS)

Balke, Tina; Eymann, Torsten

The evolution of mobile phones has lead to new wireless mobile grids that lack a central controlling instance and require the cooperation of autonomous entities that can voluntarily commit resources, forming a common pool which can be used in order to achieve common and/or individual goals. The social dilemma in such systems is that it is advantageous for rational users to access the common pool resources without any own commitment, since every commitment has its price (see ? for example). However, if a substantial number of users would follow this selfish strategy, the network itself would be at stake. Thus, the question arises on how cooperation can be fostered in wireless mobile grids. Whereas many papers have dealt with this question from a technical point of view, instead this paper will concentrate on a concept that has lately been discussed a lot with this regard: social control. Thereby social control concepts will be contrasted to technical approaches and resulting challenges (as well as possible solutions to these challenges) for social concepts will be discussed.

Visitor evaluations of management actions at a highly impacted Appalachian Trail camping area.

Protected area management involves balancing environmental and social objectives. This is particularly difficult at high-use/high-impact recreation sites, because resource protection objectives may require substantial site management or visitor regulation. This study examined visitors' reactions to both of these types of actions at Annapolis Rocks, Maryland, a popular Appalachian Trail camping area. We surveyed visitors before and after implementation of camping policies that included shifting camping to designated newly constructed campsites and prohibiting campfires. Survey results reveal that visitors were more satisfied with all social and environmental indicators after the changes were enacted. An Importance-Performance analysis also determined that management actions improved conditions for factors of greatest concern to campers prior to the changes. Posttreatment visitors were least satisfied with factors related to reduced freedom and to some characteristics of the constructed campsites. Although there was evidence of visitor displacement, the camping changes met management goals by protecting the camping area's natural resources and improving social conditions.

Turley, Matt; Bilotta, Gary; Brazier, Richard; Extence, Chris

2014-05-01

Sediment is an essential component of freshwater ecosystems; however anthropogenic activities can lead to elevated sediment delivery which can impact on the physical, chemical and biological characteristics of these ecosystems. Ultimately, this can result in a loss of ecosystem services worth more than 1.7 trillion per annum. As such it is important that sediment, which is one of the most commonly attributed causes of water quality impairment globally, is managed in order to minimise these impacts. The current EU environmental quality standard for sediment (monitored in the form of suspended solids) is 25 mg L-1 for all environments. It is widely recognised that this standard is unsuitable and not ecologically relevant. Furthermore, it requires a substantial resource investment to monitor sediment in this form as part of national and international water resource legislation. In recognition of this the development of sediment-specific biomonitoring tools is receiving increasing attention. The Proportion of Sediment-Sensitive Invertebrates (PSI) index is one such tool that is designed to indicate levels of fine sediment (

Objective The authors examined the feasibility of conducting serologic testing for the herpes simplex virus 2 (HSV-2) among university students and assessed the psychosocial impact of an HSV-2 diagnosis. Methods The authors recruited a convenience sample of 100 students (aged 18–39 years) without a history of genital herpes from 1 university between September 2004 and March 2006. Participants received HSV-2 antibody testing by Focus ELISA and Western Blot assays and completed a questionnaire that addressed psychological functioning. Twenty-eight participants completed the questionnaire again at a 3-month follow-up visit. Results The study revealed (1) low test-reliability in the student population, (2) that positive test results may cause a decline in psychological well-being, and (3) that substantial resources are required to support students with positive HSV-2 results. Conclusions Test performance, psychological impact, and availability of resources for counseling students with positive diagnoses should be considered before implementing HSV testing programs.

The Metamorphosis of Amphibian Toxicogenomics

PubMed Central

Helbing, Caren C.

2012-01-01

Amphibians are important vertebrates in toxicology often representing both aquatic and terrestrial forms within the life history of the same species. Of the thousands of species, only two have substantial genomics resources: the recently published genome of the Pipid, Xenopus (Silurana) tropicalis, and transcript information (and ongoing genome sequencing project) of Xenopus laevis. However, many more species representative of regional ecological niches and life strategies are used in toxicology worldwide. Since Xenopus species diverged from the most populous frog family, the Ranidae, ~200 million years ago, there are notable differences between them and the even more distant Caudates (salamanders) and Caecilians. These differences include genome size, gene composition, and extent of polyploidization. Application of toxicogenomics to amphibians requires the mobilization of resources and expertise to develop de novo sequence assemblies and analysis strategies for a broader range of amphibian species. The present mini-review will present the advances in toxicogenomics as pertains to amphibians with particular emphasis upon the development and use of genomic techniques (inclusive of transcriptomics, proteomics, and metabolomics) and the challenges inherent therein.

Ignaz Semmelweis redux?

PubMed

Raemer, Daniel B

2014-06-01

The story of Ignaz Semmelweis suggests a lesson to beware of unintended consequences, especially with in situ simulation. In situ simulation offers many important advantages over center-based simulation such as learning about the real setting, putting participants at ease, saving travel time, minimizing space requirements, involving patients and families. Some substantial disadvantages include frequent distractions, lack of privacy, logistics of setup, availability of technology, and supply costs. Importantly, in situ simulation amplifies some of the safety hazards of simulation itself including maintaining control of simulated medications and equipment, limiting the use of valuable hospital resources, preventing incorrect learning from simulation shortcuts, and profoundly upsetting patients and their families. Mitigating these hazards by labeling effectively, publishing policies and procedures, securing simulation supplies and equipment, educating simulation staff, and informing participants of the risks are all methods that may lessen the potential for an accident. Each requires a serious effort of analysis, design, and implementation.

Clinical decision support can improve the quality of care, but requires substantial knowledge management activities. At NewYork-Presbyterian Hospital in New York City, we have implemented a formal alert management process whereby only hospital committees and departments can request alerts. An explicit requestor, who will help resolve the details of the alert logic and the alert message must be identified. Alerts must be requested in writing using a structured alert request form. Alert requests are reviewed by the Alert Committee and then forwarded to the Information Systems department for a software development estimate. The model required that clinical committees and departments become more actively involved in the development of alerts than had previously been necessary. In the 12 months following implementation, 10 alert requests were received. The model has been well received. A lot of the knowledge engineering work has been distributed and burden has been removed from scarce medical informatics resources. PMID:16779073

A comparison of campfire impacts and policies in seven protected areas

Reid, S.E.; Marion, J.L.

2005-01-01

Using resource-monitoring data from seven protected areas, the effectiveness of three campfire policies-campfire ban, designated campfires, and unregulated campfires-were assessed based on the number of fire sites and the amount of tree damage. Results indicate that unregulated campfire policies permitted substantial numbers of fire sites and tree damage in campsites, although fire bans did not eliminate or even substantially decrease these problems. A designated campfire policy was effective in decreasing number of fire sites, but little difference was found among policies regarding tree damage. Given the importance of campfires to visitor experiences, campfire prohibitions could be viewed as unnecessarily restrictive based on their limited success in preventing resource damage. Conclusions encourage protected-area managers to consider designated campfire policies and prohibitions on axes, hatchets, and saws to better meet resource protection and visitor experience mandates.

Cells respond to their structural surrounding and within nanostructures exhibit unique proliferative and differentiation properties. The application of nanotechnologies to the field of regenerative medicine offers the potential to direct cell fate, target the delivery of cells and reduce immune rejection (via encapsulation), thereby supporting the development of regenerative medicines. The overall objective of any therapy is the delivery of the product not just into the clinic but also to patients on a routine basis. Such a goal typically requires a commercial vehicle and substantial levels of investment in scientific, clinical, regulatory and business expertise, resources, time and funding. Therefore, this paper focuses on some of the challenges facing this emerging industry, including investment by the venture capital community. PMID:20826478

2008-05-01

To date, no study has evaluated the potential impact of supplemental restraint use on resource use at a Level I trauma center. We hypothesized that airbag use would be related to decreased injury severity of motor vehicle collision survivors admitted to a Level I trauma center, leading to a decrease in infectious morbidity and hospital resource use. Using the trauma registry, motor vehicle collision victims admitted during an 11-year period were identified. Restraint groups were defined as unrestrained (reference group), seatbelt only, airbag only, or airbag and seatbelt. Multivariable logistic regression was used to determine the relationship between restraint type and injury patterns. Other outcomes measured included prevalence of ventilator-associated pneumonia and bacteremia, hospital length of stay, days in the ICU, and hospital mortality. A total of 14,390 patients (unrestrained, n = 7,881; airbag only, n = 692; seatbelt only, n = 4,909; airbag and seatbelt, n = 908) had restraint data available. Both airbag and seatbelt use were associated with a substantial reduction in injury to the brain, face, cervical spine, thorax, and abdomen. The largest reduction occurred when these restraints were used in combination. The only injury associated with airbag deployment was extremity fractures. Compared with unrestrained persons, any restraint use was associated with substantially reduced injury severity, significant infectious morbidity, and resource use. Airbags are associated with reduced in-hospital mortality. Airbags are also associated with decreased injury severity, substantial infectious morbidity, and resource use. Cost savings from reduced resource use associated with supplemental restraints could be tremendous.

Stakeholder Alignment for Requirements in GEOValue

Observation systems that collect information on environmental parameters relevant to biological and physical earth resources provide value. This has been demonstrated so many times in so many ways that it is not worth deliberating. Earlier projects for research (whether it is possible to do this or that), or for "dual use," typically involving defense, have been successful. Wealthy parties have built their own systems. Less wealthy parties seek to sustain the systems they have built. The history of systems suggests that "requirements" will be the next step. The objective is to maximize the "return" on the substantial investment required for construction, deployment, maintenance and renewal of observation systems. Stakeholders and their interests are assessed to construct the requirements from which specifications are built. Specifications drive procurement, and procurement produces built systems. Complicated (e.g. space-based) systems have long times between requirements analysis and deployment. It all depends on getting the requirements right, which depends on understanding stakeholders and requirements. And this is where things get complicated. Stakeholders and interests change, sometimes rapidly, as what is possible is altered. It becomes increasingly difficult to achieve stakeholder alignment required for effective management of constituent politics at the heart of any expensive endeavor. This paper presents results from a major study of stakeholder alignment in the Earth Sciences, focused especially on EarthCube.

Like other transformative healthcare initiatives, patient-centered medical home (PCMH) implementation requires substantial investments of time and resources. Even though PCMH and PCMH-like models are being implemented by multiple provider practices and health systems, little is known about what facilitates their implementation. The purpose of this study was to assess which PCMH-implementation resources are most widely used, by whom, and which resources primary care personnel find most helpful. This study is an analysis of data from a cross-sectional survey of primary care personnel in the Veterans Health Administration in 2012, in which respondents were asked to rate whether they were aware of and accessed PCMH-implementation resources, and to rate their helpfulness. Logistic regression was used to produce odds ratios for the outcomes (1) resource use and (2) resource helpfulness. Respondents were nested within clinics, nested, in turn, within 135 parent hospitals. Teamlet huddles were the most widely accessed (80.4% accessed) and most helpful (90.4% rated helpful) resource; quality-improvement methods to conduct small tests of change were the least frequently accessed (42.4% accessed) resource though two-thirds (66.7%) of users reported as helpful. Supervisors were significantly more likely (ORs, 1.46 to 1.86) to use resources than non-supervisors but were less likely to rate the majority (8 out of 10) of resources as "somewhat/very helpful" than non-supervisors (ORs, 0.72 to 0.84). Longer-tenured employees tended to rate resources as more helpful. These findings are the first in the PCMH literature that we are aware of that systematically assesses primary care staff's access to and the helpfulness of PCMH implementation resources. Supervisors generally reported greater access to resources, relative to non-supervisors, but rated resources as less helpful, suggesting that information about them may not have been optimally disseminated. Knowing what resources primary care staff use and find helpful can inform administrators' and policymakers' investments in PCMH-implementation resources. The implications of our model extend beyond just PCMH implementation but also to considerations when providing implementation resources for other complex quality-improvement initiatives.

SALMON RIVER BREAKS PRIMITIVE AREA AND VICINITY, IDAHO.

A mineral survey of the Salmon River Breaks Primitive Area and vicinity in Idaho confirmed a substantiated gold resource potential in placer deposits along the Salmon River but determined that large-scale mining of the deposits probably would not be feasible. Except for demonstrated fluorspar resources at the Big Squaw Creek deposit, no other mineral resources were found in the area. The geologic environment, geochemical findings, and geophysical data all suggest little likelihood for the occurrence of additional mineral resources in the area. No energy resources were identified in this study.

A task shifting approach to primary mental health care for adults in South Africa: human resource requirements and costs for rural settings.

Petersen, Inge; Lund, Crick; Bhana, Arvin; Flisher, Alan J

BACKGROUND A recent situational analysis suggests that post-apartheid South Africa has made some gains with respect to the decentralization and integration of mental health into primary health care. However, service gaps within and between provinces remain, with rural areas particularly underserved. Aim This study aims to calculate and cost a hypothetical human resource mix required to populate a framework for district adult mental health services. This framework embraces the concept of task shifting, where dedicated low cost mental health workers at the community and clinic levels supplement integrated care. METHOD The expected number and cost of human resources was based on: (a) assumptions of service provision derived from existing services in a sub-district demonstration site and a literature review of evidence-based packages of care in low- and middle-income countries; and (b) assumptions of service needs derived from other studies. RESULTS For a nominal population of 100 000, minimal service coverage estimates of 50% for schizophrenia, bipolar affective disorder, major depressive disorder and 30% for post-traumatic stress disorder and maternal depression would require that the primary health care staffing package include one post for a mental health counsellor or equivalent and 7.2 community mental health worker posts. The cost of these personnel amounts to £28 457 per 100 000 population. This cost can be offset by a reduction in the number of other specialist and non-specialist health personnel required to close service gaps at primary care level. CONCLUSION The adoption of the concept of task shifting can substantially reduce the expected number of health care providers otherwise needed to close mental health service gaps at primary health care level in South Africa at minimal cost and may serve as a model for other middle-income countries.

Community characteristics associated with child abuse in Iowa.

Weissman, Alicia M; Jogerst, Gerald J; Dawson, Jeffrey D

2003-10-01

Various demographic and community characteristics are associated with child abuse rates in national and urban samples, but similar analyses have not been done within rural areas. This study analyzes the relationships between reported and substantiated rates of child abuse and county demographic, health care resource and social services factors in a predominantly rural state in the US. County-level data from Iowa between 1984-1993 were analyzed for associations between county characteristics and rates of child abuse using univariate correlations and multivariate stagewise regression analysis. Population-adjusted rates of reported and substantiated child abuse were correlated with rates of children in poverty, single-parent families, marriage and divorce, unemployment, high-school dropouts, median family income, elder abuse, birth and death rates, numbers of physicians and other healthcare providers, hospital, social workers, and number of caseworkers in the Department of Human Services. Rates of single-parent families, divorce and elder abuse were significantly associated with reported and substantiated child abuse in multivariate analysis, while economic and most health care factors were not. Reporting and substantiation rates differed across districts after adjustment for multiple factors including caseworker workload. In this rural state, family structure is more significantly associated with child abuse report and substantiation rates than are socioeconomic factors. The level of health care resources in a county does not appear to affect these rates.

Constraint based scheduling for the Goddard Space Flight Center distributed Active Archive Center's data archive and distribution system

The Goddard Space Flight Center (GSFC) Distributed Active Archive Center (DAAC) has been operational since October 1, 1993. Its mission is to support the Earth Observing System (EOS) by providing rapid access to EOS data and analysis products, and to test Earth Observing System Data and Information System (EOSDIS) design concepts. One of the challenges is to ensure quick and easy retrieval of any data archived within the DAAC's Data Archive and Distributed System (DADS). Over the 15-year life of EOS project, an estimated several Petabytes (10(exp 15)) of data will be permanently stored. Accessing that amount of information is a formidable task that will require innovative approaches. As a precursor of the full EOS system, the GSFC DAAC with a few Terabits of storage, has implemented a prototype of a constraint-based task and resource scheduler to improve the performance of the DADS. This Honeywell Task and Resource Scheduler (HTRS), developed by Honeywell Technology Center in cooperation the Information Science and Technology Branch/935, the Code X Operations Technology Program, and the GSFC DAAC, makes better use of limited resources, prevents backlog of data, provides information about resources bottlenecks and performance characteristics. The prototype which is developed concurrently with the GSFC Version 0 (V0) DADS, models DADS activities such as ingestion and distribution with priority, precedence, resource requirements (disk and network bandwidth) and temporal constraints. HTRS supports schedule updates, insertions, and retrieval of task information via an Application Program Interface (API). The prototype has demonstrated with a few examples, the substantial advantages of using HTRS over scheduling algorithms such as a First In First Out (FIFO) queue. The kernel scheduling engine for HTRS, called Kronos, has been successfully applied to several other domains such as space shuttle mission scheduling, demand flow manufacturing, and avionics communications scheduling.

Fri, R.W.

Now that analysts have had seven months to ponder the achievements of the Earth Summit, it is time to consider the next step in attaining sustainable development. As the summit revealed, the big issues are formidable - among them, overconsumption in the North, overpopulation in the South, insufficient resource transfers from North to South, and limited resources to devote to global environmental problems. Each of these issues requires a trade-off between long-term global concerns and immediate national interests. Since technological solutions to the dilemma of furthering economic development are neither quick nor cheap, this political reality suggests that progress maymore » hinge on attention to some modest goals. Helping developing countries to define and balance their own economic and environmental priorities, and using these priorities to guide the planning of both public and private sector investments, would be welcome signs of progress. Such feasible and inexpensive assistance would exert useful leverage over the substantial transfers of financial and technological resources that are already taking place, especially in the private sector. Equally encouraging would be growing investments in the development of technology to use natural and environmental resources more efficiently and in creating the market and other institutional mechanisms needed to assure use of these technologies. Efficient resource use may not prove to be a complete answer to the big questions of environment and development, much less one with no regrets. However, it will at least reduce the cost of dealing with the hard issues, and so make them more tractable.« less

Economic and financial evaluation of neglected tropical diseases.

Lee, Bruce Y; Bartsch, Sarah M; Gorham, Katrin M

2015-03-01

Economic and financing studies are particularly important for decision-making when resources are scarce or considerably limited. This is the case for neglected tropical diseases (NTDs). In fact, the definition of NTDs is an economic one. The shortage of resources for NTD control may be due in large part to the fact that the burden of NTDs and economic value of control measures have not been fully characterized. A number of economic study methodologies are available: cost of illness can quantify the extent, magnitude, and change of a problem; cost of intervention studies can outline the feasibility and guide the design of a policy or intervention; and cost-benefit, cost-effectiveness, and return-on-investment studies can determine the potential value of different interventions and policies. NTDs have unique characteristics that require special consideration in such analyses. Hence, approaches used for other diseases may need modifications to capture the full impact of NTDs. While the existing literature has made important findings, there is a need for substantially more work, as many NTDs and their associated interventions and policies require more evaluation. With increasing work in this area, NTDs may not be as 'neglected' in the future as they are now. Copyright © 2015 Elsevier Ltd. All rights reserved.

Sepsis is a major reason for intensive care unit (ICU) admission, also in resource-poor settings. ICUs in low- and middle-income countries (LMICs) face many challenges that could affect patient outcome. To describe differences between resource-poor and resource-rich settings regarding the epidemiology, pathophysiology, economics and research aspects of sepsis. We restricted this manuscript to the ICU setting even knowing that many sepsis patients in LMICs are treated outside an ICU. Although many bacterial pathogens causing sepsis in LMICs are similar to those in high-income countries, resistance patterns to antimicrobial drugs can be very different; in addition, causes of sepsis in LMICs often include tropical diseases in which direct damaging effects of pathogens and their products can sometimes be more important than the response of the host. There are substantial and persisting differences in ICU capacities around the world; not surprisingly the lowest capacities are found in LMICs, but with important heterogeneity within individual LMICs. Although many aspects of sepsis management developed in rich countries are applicable in LMICs, implementation requires strong consideration of cost implications and the important differences in resources. Addressing both disease-specific and setting-specific factors is important to improve performance of ICUs in LMICs. Although critical care for severe sepsis is likely cost-effective in LMIC setting, more detailed evaluation at both at a macro- and micro-economy level is necessary. Sepsis management in resource-limited settings is a largely unexplored frontier with important opportunities for research, training, and other initiatives for improvement.

Characterizing new compositions of [001]C relaxor ferroelectric single crystals using a work-energy model

NASA Astrophysics Data System (ADS)

Gallagher, John A.

2016-04-01

The desired operating range of ferroelectric materials with compositions near the morphotropic phase boundary is limited by field induced phase transformations. In [001]C cut and poled relaxor ferroelectric single crystals the mechanically driven ferroelectric rhombohedral to ferroelectric orthorhombic phase transformation is hindered by antagonistic electrical loading. Instability around the phase transformation makes the current experimental technique for characterization of the large field behavior very time consuming. Characterization requires specialized equipment and involves an extensive set of measurements under combined electrical, mechanical, and thermal loads. In this work a mechanism-based model is combined with a more limited set of experiments to obtain the same results. The model utilizes a work-energy criterion that calculates the mechanical work required to induce the transformation and the required electrical work that is removed to reverse the transformation. This is done by defining energy barriers to the transformation. The results of the combined experiment and modeling approach are compared to the fully experimental approach and error is discussed. The model shows excellent predictive capability and is used to substantially reduce the total number of experiments required for characterization. This decreases the time and resources required for characterization of new compositions.

2018-02-20

While the demand for health services keep escalating at the grass roots or rural areas of China, a substantial portion of healthcare resources remain stagnant in the more developed cities and this has entrenched health inequity in many parts of China. At its conception, China's Deepen Medical Reform started in 2012 was intended to flush out possible disparities and promote a more equitable and efficient distribution of healthcare resources. Nearly half a decade of this reform, there are uncertainties as to whether the attainment of the objectives of the reform is in sight. Using a hybrid of panel data analysis and an augmented data envelopment analysis (DEA), we model human resources, material, finance to determine their technical and scale efficiency to comprehensively evaluate the transverse and longitudinal allocation efficiency of community health resources in Jiangsu Province. We observed that the Deepen Medical Reform in China has led to an increase concern to ensure efficient allocation of community health resources by health policy makers in the province. This has led to greater efficiency in health resource allocation in Jiangsu in general but serious regional or municipal disparities still exist. Using the DEA model, we note that the output from the Community Health Centers does not commensurate with the substantial resources (human resources, materials, and financial) invested in them. We further observe that the case is worst in less-developed Northern parts of Jiangsu Province. The government of Jiangsu Province could improve the efficiency of health resource allocation by improving the community health service system, rationalizing the allocation of health personnel, optimizing the allocation of material resources, and enhancing the level of health of financial resource allocation.

Successive quit smoking contests undertaken as part of the Minnesota Heart Health Program had generated diminishing impact. The 1988 contest attempted to rejuvenate community interest and participation through a substantially extended enrollment period. Smokers were eligible for monthly prize drawings and a grand prize drawing by entering the contest at any point between June 1988 and January 1989 and remaining abstinent for at least one month. The contest was promoted through newspaper advertisements, contest flyers, schools, and a community-wide direct mail campaign. A total of 1,328 smokers returned initial interest cards and 918 (69.1%) of these smokers returned quit pledges. Self-reported abstinence for pledgers and nonpledgers was 16.7% and 9.2%, respectively. Survival analysis indicated significantly longer periods of abstinence for pledgers (p = .0001). The extended contest was successful in recruiting smokers (almost 7% of the entire Bloomington smoking population vs. 1% for a previous one-month contest), especially those with less than a high school education. The current contest required substantial expenditures. However, these costs could be dramatically reduced through innovative use of donated resources.

From Ships in the Night to Exchanges in the Piazza: Renegotiating the Researcher-Stakeholder Nexus in Climate Adaptation

A substantial divide remains between the communities of research, embedded largely in universities and science agencies, and the communities of practice, comprising the natural-resource managers and other decision-makers in diverse federal, state, local, and tribal agencies and in private-sector enterprises and organizations. In spite of clear needs and best intentions, engagement among the respective communities is imperfect; researchers and stakeholders are often like ships passing in the night, exchanging brief, cryptic signals. A variety of boundary organizations have been developed to facilitate the communications, and a number of successful models for researcher-stakeholder exchange and engagement have been applied. At least two substantial challenges remain. First, how can the successes be scaled up and proliferated to meet the vast demands posed by climate adaptation? Second, how can the various boundary organizations most effectively foster this expansion, individually and collectively? Meeting these challenges will require coordination among the respective organizations, changes in the cultures of research and management, and careful assessment of process and outcomes.

AN ANALYSIS OF THE INEQUALITIES BETWEEN THE PUBLIC AND PRIVATE SECTOR IN SOUTH AFRICA.

2017-06-01

The full extent of the global burden of surgical disease is largely unknown; however, the scope of the problem is thought to be large. Despite the substantial burden of surgical disease, surgical services are inaccessible to many of those who need them most. There are disparities between public and private sectors in South Africa, which compounds inequitable access to surgical care. This study involved a descriptive analysis of surgical resources and included the total number of hospitals, hospital beds, surgical beds, general surgeons (specialist and nonspecialist), and the number of functional operating theatres in South Africa. A comparison was performed between the public sector resources per uninsured population and private sector resources per insured population. Hospitals were contacted during the period 01 October 2014 to 31 December 2014. Surgical resources were concentrated in metropolitan areas of urban provinces. There were striking differences between sectors when a comparison was made between patients with and without health insurance. Private resources were comparable to those available in high income countries (HICs) and were accessible to only 16% of South Africans. Improving access to surgical services in lower middle income countries (LMICs) requires addressing gaps between the public and private sector regarding infrastructure, personnel, as well as equipment. South Africa is unique in that although it is classified as an upper middle income country (UMIC), it comprises of two sectors; a public sector which has resources similar to other LMICs, and a private sector which has resources similar to HICs. These data identified disparities between geographic regions which may be contributing to ongoing inequity in South Africa, and by doing so allows for evidence-based planning towards improving surgical infrastructure and workforce.

Human trafficking is an increasingly well-recognized human rights violation that is estimated to involve more than 2 million victims worldwide each year. The health consequences of this issue bring victims into contact with health systems and healthcare providers, thus providing the potential for identification and intervention. A robust healthcare response, however, requires a healthcare workforce that is aware of the health impact of this issue; educated about how to identify and treat affected individuals in a compassionate, culturally aware, and trauma-informed manner; and trained about how to collaborate efficiently with law enforcement, case management, and advocacy partners. This article describes existing educational offerings about human trafficking designed for a healthcare audience and makes recommendations for further curriculum development. A keyword search and structured analysis of peer-reviewed and gray literature, conducted in 2011 and 2012, yielded 27 items that provide basic guidance to health professionals on human trafficking. The 27 resources differed substantially in format, length, scope, and intended audience. Topic areas covered by these resources included trafficking definitions and scope, health consequences, victim identification, appropriate treatment, referral to services, legal issues, and security. None of the educational resources has been rigorously evaluated. There is a clear need to develop, implement, and evaluate high-quality education and training programs that focus on human trafficking for healthcare providers.

Commercial possibilities for stranded conventional gas from Alaska's North Slope

Attanasi, E.D.; Freeman, P.A.

2014-01-01

Stranded gas resources are defined for this study as gas resources in discrete accumulations that are not currently commercially producible, or producible at full potential, for either physical or economic reasons. Approximately 35 trillion cubic feet (TCF) of stranded gas was identified on Alaska’s North Slope. The commercialization of this resource requires facilities to transport gas to markets where sales revenue will be sufficient to offset the cost of constructing and operating a gas delivery system. With the advent of the shale gas revolution, plans for a gas pipeline to the conterminous US have been shelved (at least temporarily) and the State and resource owners are considering a liquefied natural gas (LNG) export project that targets Asian markets. This paper focuses on competitive conditions for Asian gas import markets by estimating delivered costs of competing supplies from central Asia, Russia, Indonesia, Malaysia, and Australia in the context of a range of import gas demand projections for the period from 2020 to 2040. These suppliers’ costs are based on the cost of developing, producing, and delivering to markets tranches of the nearly 600 TCF of recoverable gas from their own conventional stranded gas fields. The results of these analyses imply that Alaska’s gas exports to Asia will likely encounter substantial competitive challenges. The sustainability of Asia’s oil-indexed LNG pricing is also discussed in light of a potentially intense level of competition.

Application of microarray analysis on computer cluster and cloud platforms.

Analysis of recent high-dimensional biological data tends to be computationally intensive as many common approaches such as resampling or permutation tests require the basic statistical analysis to be repeated many times. A crucial advantage of these methods is that they can be easily parallelized due to the computational independence of the resampling or permutation iterations, which has induced many statistics departments to establish their own computer clusters. An alternative is to rent computing resources in the cloud, e.g. at Amazon Web Services. In this article we analyze whether a selection of statistical projects, recently implemented at our department, can be efficiently realized on these cloud resources. Moreover, we illustrate an opportunity to combine computer cluster and cloud resources. In order to compare the efficiency of computer cluster and cloud implementations and their respective parallelizations we use microarray analysis procedures and compare their runtimes on the different platforms. Amazon Web Services provide various instance types which meet the particular needs of the different statistical projects we analyzed in this paper. Moreover, the network capacity is sufficient and the parallelization is comparable in efficiency to standard computer cluster implementations. Our results suggest that many statistical projects can be efficiently realized on cloud resources. It is important to mention, however, that workflows can change substantially as a result of a shift from computer cluster to cloud computing.

Some Strategic Considerations Related to the Potential Use of Water Resource Deposits on Mars by Future Human Explorers

A long-term base on Mars, at the center of an "Exploration Zone", would require substantial quantities of in-situ resources. Although water is not the only resource on Mars of potential interest, it stands out as the one that most dominates long-lead strategic planning. It is needed for multiple purposes for various human activities (including our own survival!), and in significant quantities. The absence of viable deposits could make a surface "field station" logistically unsustainable. Therefore, identification of deposits, and development of the technology needed to make use of these deposits, are an important priority in the period leading up to a human mission to Mars. Given our present understanding of Mars, ice and hydrated minerals appear to be the best potential sources for the quantity of water expected to be needed. The methods for their extraction would be different for these two classes of deposits, and at the present time it is unknown which would ultimately be an optimal solution. The deposits themselves would also ultimately have to be judged by certain economics that take into account information about geologic and engineering attributes and the "cost" of obtaining this information. Ultimately much of this information would need to come from precursor missions, which would be essential if utilization of martian is situ water resources is to become a part of human exploration of Mars.

Telescience Support Center Data System Software

2010-01-01

The Telescience Support Center (TSC) team has developed a databasedriven, increment-specific Data Require - ment Document (DRD) generation tool that automates much of the work required for generating and formatting the DRD. It creates a database to load the required changes to configure the TSC data system, thus eliminating a substantial amount of labor in database entry and formatting. The TSC database contains the TSC systems configuration, along with the experimental data, in which human physiological data must be de-commutated in real time. The data for each experiment also must be cataloged and archived for future retrieval. TSC software provides tools and resources for ground operation and data distribution to remote users consisting of PIs (principal investigators), bio-medical engineers, scientists, engineers, payload specialists, and computer scientists. Operations support is provided for computer systems access, detailed networking, and mathematical and computational problems of the International Space Station telemetry data. User training is provided for on-site staff and biomedical researchers and other remote personnel in the usage of the space-bound services via the Internet, which enables significant resource savings for the physical facility along with the time savings versus traveling to NASA sites. The software used in support of the TSC could easily be adapted to other Control Center applications. This would include not only other NASA payload monitoring facilities, but also other types of control activities, such as monitoring and control of the electric grid, chemical, or nuclear plant processes, air traffic control, and the like.

Health care priority setting: principles, practice and challenges

PubMed Central

Mitton, Craig; Donaldson, Cam

2004-01-01

Background Health organizations the world over are required to set priorities and allocate resources within the constraint of limited funding. However, decision makers may not be well equipped to make explicit rationing decisions and as such often rely on historical or political resource allocation processes. One economic approach to priority setting which has gained momentum in practice over the last three decades is program budgeting and marginal analysis (PBMA). Methods This paper presents a detailed step by step guide for carrying out a priority setting process based on the PBMA framework. This guide is based on the authors' experience in using this approach primarily in the UK and Canada, but as well draws on a growing literature of PBMA studies in various countries. Results At the core of the PBMA approach is an advisory panel charged with making recommendations for resource re-allocation. The process can be supported by a range of 'hard' and 'soft' evidence, and requires that decision making criteria are defined and weighted in an explicit manner. Evaluating the process of PBMA using an ethical framework, and noting important challenges to such activity including that of organizational behavior, are shown to be important aspects of developing a comprehensive approach to priority setting in health care. Conclusion Although not without challenges, international experience with PBMA over the last three decades would indicate that this approach has the potential to make substantial improvement on commonly relied upon historical and political decision making processes. In setting out a step by step guide for PBMA, as is done in this paper, implementation by decision makers should be facilitated. PMID:15104792

Throughout the western United States, increased demand for energy is driving the rapid development of oil, gas (including shale gas and coal-bed methane), and uranium, as well as renewable energy resources such as geothermal, solar, and wind. Much of the development in the West is occurring on public lands, including those under Federal and State jurisdictions. In Colorado and New Mexico, these public lands make up about 40 percent of the land area. Both states benefit from the revenue generated by energy production, but resource managers and other decisionmakers must balance the benefits of energy development with the potential consequences for ecosystems, recreation, and other resources. Although a substantial amount of geospatial data on existing energy development and energy potential is available, much of this information is not readily accessible to natural resource decisionmakers, policymakers, or the public. Furthermore, the data often exist in varied formats, requiring considerable processing before these datasets can be used to evaluate tradeoffs among resources, compare development alternatives, or quantify cumulative impacts. To allow for a comprehensive evaluation among different energy types, an interdisciplinary team of U.S. Geological Survey (USGS) scientists has developed an online Interactive Energy Atlas for Colorado and New Mexico. The Energy and Environment in the Rocky Mountain Area (EERMA) interdisciplinary team includes investigators from several USGS science centers1. The purpose of the EERMA Interactive Energy Atlas is to facilitate access to geospatial data related to energy resources, energy infrastructure, and natural resources that may be affected by energy development. The Atlas is designed to meet the needs of various users, including GIS analysts, resource managers, policymakers, and the public, who seek information about energy in the western United States. Currently, the Atlas has two primary capabilities, a GIS data viewer and an interactive map gallery.

The role of law enforcement in schools: the Virginia experience--a practitioner report.

Clark, Steven

2011-01-01

Although there has been little academic research on the impact of placing police officers in schools, this practice has grown substantially in response to school shootings and other violent crimes in schools. With a standardized training program since 1999, the state of Virginia has law enforcement officers working in approximately 88 percent of Virginia's 631 secondary schools. Based on this experience, the state training coordinator describes how police officers should be selected and prepared to work as school resource officers. The success of school-based law enforcement requires careful selection and specialized training of officers who can adapt to the school culture and work collaboratively with school authorities.

Preuße, Marie; Bokarev, Sergey I; Aziz, Saadullah G; Kühn, Oliver

2016-11-01

The Frenkel exciton model was adapted to describe X-ray absorption and resonant inelastic scattering spectra of polynuclear transition metal complexes by means of the restricted active space self-consistent field method. The proposed approach allows to substantially decrease the requirements on computational resources if compared to a full supermolecular quantum chemical treatment. This holds true, in particular, in cases where the dipole approximation to the electronic transition charge density can be applied. The computational protocol was applied to the calculation of X-ray spectra of the hemin complex, which forms dimers in aqueous solution. The aggregation effects were found to be comparable to the spectral alterations due to the replacement of the axial ligand by solvent molecules.

CSI Feedback Reduction for MIMO Interference Alignment

NASA Astrophysics Data System (ADS)

Rao, Xiongbin; Ruan, Liangzhong; Lau, Vincent K. N.

2013-09-01

Interference alignment (IA) is a linear precoding strategy that can achieve optimal capacity scaling at high SNR in interference networks. Most of the existing IA designs require full channel state information (CSI) at the transmitters, which induces a huge CSI signaling cost. Hence it is desirable to improve the feedback efficiency for IA and in this paper, we propose a novel IA scheme with a significantly reduced CSI feedback. To quantify the CSI feedback cost, we introduce a novel metric, namely the feedback dimension. This metric serves as a first-order measurement of CSI feedback overhead. Due to the partial CSI feedback constraint, conventional IA schemes can not be applied and hence, we develop a novel IA precoder / decorrelator design and establish new IA feasibility conditions. Via dynamic feedback profile design, the proposed IA scheme can also achieve a flexible tradeoff between the degree of freedom (DoF) requirements for data streams, the antenna resources and the CSI feedback cost. We show by analysis and simulations that the proposed scheme achieves substantial reductions of CSI feedback overhead under the same DoF requirement in MIMO interference networks.

Risk of post-fire metal mobilization into surface water resources: A review.

PubMed

Abraham, Joji; Dowling, Kim; Florentine, Singarayer

2017-12-01

One of the significant economic benefits to communities around the world of having pristine forest catchments is the supply of substantial quantities of high quality potable water. This supports a saving of around US$ 4.1 trillion per year globally by limiting the cost of expensive drinking water treatments and provision of unnecessary infrastructure. Even low levels of contaminants specifically organics and metals in catchments when in a mobile state can reduce these economic benefits by seriously affecting the water quality. Contamination and contaminant mobility can occur through natural and anthropogenic activities including forest fires. Moderate to high intensity forest fires are able to alter soil properties and release sequestered metals from sediments, soil organic matter and fragments of vegetation. In addition, the increase in post-fire erosion rate by rainfall runoff and strong winds facilitates the rapid transport of these metals downslope and downstream. The subsequent metal deposition in distal soil and water bodies can influence surface water quality with potential impacts to the larger ecosystems inclusive of negative effects on humans. This is of substantial concern as 4 billion hectares of forest catchments provide high quality water to global communities. Redressing this problem requires quantification of the potential effects on water resources and instituting rigorous fire and environmental management plans to mitigate deleterious effects on catchment areas. This paper is a review of the current state of the art literature dealing with the risk of post-fire mobilization of the metals into surface water resources. It is intended to inform discussion on the preparation of suitable management plans and policies during and after fire events in order to maintain potable water quality in a cost-effective manner. In these times of climate fluctuation and increased incidence of fires, the need for development of new policies and management frameworks are of heighted significance. Copyright © 2017 Elsevier B.V.

Gambling in Finland: problem gambling in the context of a national monopoly in the European Union.

Tammi, Tuukka; Castrén, Sari; Lintonen, Tomi

2015-05-01

To describe and analyse the Finnish gambling market, regulatory system and the state of gambling research as well as the treatment system in operation for problem gamblers. A review of the literature and official documents relating to gambling in Finland, focusing primarily on the 1990s and 2000s. Only in recent years have gambling problems become a major issue for public debate in Finland. One reason for the increase in activity to address gambling problems is that, after Finland became a member of the European Union in 1995, the Finnish state gambling monopoly and its compatibility with European Union (EU) regulations have been questioned repeatedly. Since 2000, the Finnish government has put significant new resources into the research as well as the prevention and treatment of gambling problems. The resources grew from almost nothing to several million Euros in less than 10 years. This could be seen as an attempt to protect the national gambling monopoly system by showing that the Finnish monopoly system meets EU requirements. Since joining the European Union in 1995, the Finnish government has been able to maintain its gambling monopoly by providing substantial resources to signal a commitment to minimizing problem gambling. © 2015 Society for the Study of Addiction.

Stingless bees (Melipona subnitida) adjust brood production rather than foraging activity in response to changes in pollen stores.

PubMed

Maia-Silva, Camila; Hrncir, Michael; Imperatriz-Fonseca, Vera Lucia; Schorkopf, Dirk Louis P

2016-10-01

Highly eusocial bees (honey bees and stingless bees) sustain their colonies through periods of resource scarcity by food stored within the nest. The protein supply necessary for successful brood production is ensured through adjustments of the colonies' pollen foraging according to the availability of this resource in the environment. In honey bees Apis mellifera, in addition, pollen foraging is regulated through the broods' demand for this resource. Here, we investigated the influence of the colony's pollen store level on pollen foraging and brood production in stingless bees (Melipona subnitida). When pollen was added to the nests, colonies increased their brood production and reduced their pollen foraging within 24 h. On the other hand, when pollen reserves were removed, colonies significantly reduced their brood production. In strong contrast to A. mellifera; however, M. subnitida did not significantly increase its pollen foraging activity under poor pollen store conditions. This difference concerning the regulation of pollen foraging may be due to differences regarding the mechanism of brood provisioning. Honey bees progressively feed young larvae and, consequently, require a constant pollen supply. Stingless bees, by contrast, mass-provision their brood cells and temporary absence of pollen storage will not immediately result in substantial brood loss.

Sustainable and tenable renal health model: a Latin American proposal of classification, programming, and evaluation.

PubMed

Calderón, Rafael Burgos; Depine, Santos

2005-08-01

End-stage renal disease (ESRD) presents a major problem to public health, with complex implications for social and economic structures in every nation of the world. Clearly, Latin American and Caribbean countries are not able to meet the needs of every patient requiring dialysis treatment at ESRD. Consequently, a considerable number of patients die every year as a result of lack of resources. Aware of this serious social, ethical, and economic problem, the Latin American Society of Nephrology and Hypertension proposed a new renal health concept in the region. In December 2002, at the workshop in Valdivia, Chile, a modification to the National Kidney Foundation Classification of Chronic Kidney Disease was approved. According to modifications to the concept of chronic kidney disease approved in the Declaration of Valdivia, a new Renal Health Model was proposed. It consists of including orderly follow-up in patients' charts, starting from the earliest stage, and a model establishing a guideline for the reallocation of financial resources to guarantee continuity of treatment to patients with ESRD. The implementation of the Renal Health Program in health ministries of Latin American and Caribbean countries would allow for a substantial improvement in renal health prevention and management, as a result of better distribution of financial and human resources.

Measuring efficiency of cotton cultivation in Pakistan: a restricted production frontier study.

PubMed

Watto, Muhammad Arif; Mugera, Amin

2014-11-01

Massive groundwater pumping for irrigation has started lowering water tables rapidly in different regions of Pakistan. Declining water tables have thus prompted research efforts to improve agricultural productivity and efficiency to make efficient use of scarce water resources. This study employs a restricted stochastic production frontier to estimate the level of, and factors affecting, technical efficiency of groundwater-irrigated cotton farms in the Punjab province of Pakistan. The mean technical efficiency estimates indicate substantial technical inefficiencies among cotton growers. On average, tube-well owners and water buyers can potentially increase cotton production by 19% and 28%, respectively, without increasing the existing input level. The most influential factors affecting technical efficiency positively are the use of improved quality seed, consultation with extension field staff and farmers' perceptions concerning the availability of groundwater resources for irrigation in the future. This study proposes that adopting improved seed for new cotton varieties and providing better extension services regarding cotton production technology would help to achieve higher efficiency in cotton farming. Within the context of falling water tables, educating farmers about the actual crop water requirements and guiding them about groundwater resource availability may also help to achieve higher efficiencies. © 2014 Society of Chemical Industry. © 2014 Society of Chemical Industry.

Does Wyoming's Core Area Policy Protect Winter Habitats for Greater Sage-Grouse?

PubMed

Smith, Kurt T; Beck, Jeffrey L; Pratt, Aaron C

2016-10-01

Conservation reserves established to protect important habitat for wildlife species are used world-wide as a wildlife conservation measure. Effective reserves must adequately protect year-round habitats to maintain wildlife populations. Wyoming's Sage-Grouse Core Area policy was established to protect breeding habitats for greater sage-grouse (Centrocercus urophasianus). Protecting only one important seasonal habitat could result in loss or degradation of other important habitats and potential declines in local populations. The purpose of our study was to identify the timing of winter habitat use, the extent which individuals breeding in Core Areas used winter habitats, and develop resource selection functions to assess effectiveness of Core Areas in conserving sage-grouse winter habitats in portions of 5 Core Areas in central and north-central Wyoming during winters 2011-2015. We found that use of winter habitats occured over a longer period than current Core Area winter timing stipulations and a substantial amount of winter habitat outside of Core Areas was used by individuals that bred in Core Areas, particularly in smaller Core Areas. Resource selection functions for each study area indicated that sage-grouse were selecting habitats in response to landscapes dominated by big sagebrush and flatter topography similar to other research on sage-grouse winter habitat selection. The substantial portion of sage-grouse locations and predicted probability of selection during winter outside small Core Areas illustrate that winter requirements for sage-grouse are not adequately met by existing Core Areas. Consequently, further considerations for identifying and managing important winter sage-grouse habitats under Wyoming's Core Area Policy are warranted.

The Economics of Transcatheter Valve Interventions.

A subset of patients who require correction of a stenotic or incompetent valve are deemed to be at excessive surgical risk, which precludes surgical repair or replacement. Transcatheter valve interventions are viable alternatives in these patients. However, these technologies are costly, and in the setting of a constrained Canadian health care budget, economic value is an important consideration to allow for fair allocation of scarce resources. Accordingly, we review the economic literature on transcatheter valve interventions, targeting a general audience. Our specific goals are highlighting how best to interpret these studies and discuss the implications of these technologies on the Canadian health care system. Transcatheter aortic valve replacement (TAVR) is a cost-effective alternative for inoperable patients who otherwise would receive medical therapy. When compared with surgical aortic valve replacement (SAVR), TAVR is associated with significant reductions in postprocedure hospital resource use, which offsets the substantially higher cost of the TAVR valve system relative to SAVR valves. Although cost-effectiveness estimates for TAVR in high-risk operable candidates vary widely across studies, based on contemporary data from the perspective of the Canadian health care system, TAVR is likely to provide economic value. Recent studies suggest that when compared with medical therapy for severe degenerative mitral regurgitation, the MitraClip (Abbott, Abbott Park, IL) may offer economic value in high-risk patients; however, in the absence of randomized controlled trials, this is speculative. Nonetheless, these transcatheter technologies represent a paradigm shift in the management of valvular disease; their dissemination will have substantial impact in cardiovascular care delivery.

A mineral survey of the Charles Sheldon Antelope Range and Sheldon National Antelope Refuge, in Humboldt and Washoe Counties, Nevada, and Lake and Harney Counties, Oregon, was conducted. The investigation identified areas of mineral-resource potential within the range and refuge. The range and refuge have areas of substantiated resource potential for precious opal and uranium, a demonstrated resource of decorative building stone, and areas with probable resource potential for mercury and for base- and precious-metal sulfide deposits. Reservoir temperatures, estimated from the analysis of thermal springs, indicate that a probable potential for geothermal resources exists in two areas in the range. No other energy resources were identitied in the area.

Recreation impacts to cliff resources in the Potomac Gorge: Final report, June 2011

2011-01-01

Managers of the National Park Service (NPS) are directed by law to accommodate appropriate types and amounts of visitation while ensuring that: any adverse impacts are the minimum necessary, unavoidable, cannot be further mitigated, and do not constitute impairment or derogation of park resources and values. (NPS 2006). The increasing popularity of the national park system presents substantial management challenges. High visitatation may cause unacceptable impacts to fragile natural and cultural resources, and may also cause crowding and other social impacts, which can also degrade the quality of visitor experiences. Responding to these concerns, NPS managers at Chesapeake & Ohio Canal National Historical Park (CHOH) and George Washington Memorial Parkway (GWMP) sponsored this research within the upper Potomac Gorge portions of these parks to investigate visitation-related impacts to the park?s cliff resources. The cliffs and rocky areas within the Great Falls and Mather Gorge areas provide important habitats for numerous sensitive rare plants and plant communities. A recent General Management Planning process for Great Falls Park (GFP), a portion of GWMP, highlighted the potential impacts of cliff-associated recreational activities, including hiking, climbing, and fishing, on sensitive cliff resources. The planning process identified the need for development of a Climbing Management Plan and a Trail Plan to more specifically address site and visitor management actions needed to protect rare and sensitive natural and cultural resources. Good science to assess cliff-associated rare plants and communities and to determine the existing and potential effects of cliff-related recreational activities is required for these new planning efforts. This research is designed to specifically address these informational needs and to assist park managers on both sides of the river with current and future cliff and recreation management decisions.

Exploiting Untapped Information Resources in Earth Science

Ramachandran, R.; Fox, P. A.; Kempler, S.; Maskey, M.

2015-12-01

One of the continuing challenges in any Earth science investigation is the amount of time and effort required for data preparation before analysis can begin. Current Earth science data and information systems have their own shortcomings. For example, the current data search systems are designed with the assumption that researchers find data primarily by metadata searches on instrument or geophysical keywords, assuming that users have sufficient knowledge of the domain vocabulary to be able to effectively utilize the search catalogs. These systems lack support for new or interdisciplinary researchers who may be unfamiliar with the domain vocabulary or the breadth of relevant data available. There is clearly a need to innovate and evolve current data and information systems in order to improve data discovery and exploration capabilities to substantially reduce the data preparation time and effort. We assert that Earth science metadata assets are dark resources, information resources that organizations collect, process, and store for regular business or operational activities but fail to utilize for other purposes. The challenge for any organization is to recognize, identify and effectively utilize the dark data stores in their institutional repositories to better serve their stakeholders. NASA Earth science metadata catalogs contain dark resources consisting of structured information, free form descriptions of data and pre-generated images. With the addition of emerging semantic technologies, such catalogs can be fully utilized beyond their original design intent of supporting current search functionality. In this presentation, we will describe our approach of exploiting these information resources to provide novel data discovery and exploration pathways to science and education communities

Natural resource manager perceptions of agency performance on climate change.

PubMed

Lemieux, Christopher J; Thompson, Jessica L; Dawson, Jackie; Schuster, Rudy M

2013-01-15

An important precursor to the adoption of climate change adaptation strategies is to understand the perceived capacity to implement and operationalize such strategies. Utilizing an importance-performance analysis (IPA) evaluation framework, this article presents a comparative case study of federal and state land and natural resource manager perceptions of agency performance on factors influencing adaptive capacity in two U.S. regions (northern Colorado and southwestern South Dakota). Results revealed several important findings with substantial management implications. First, none of the managers ranked the adaptive capacity factors as a low priority. Second, managers held the perception that their agencies were performing either neutrally or poorly on most factors influencing adaptive capacity. Third, gap analysis revealed that significant improvements are required to facilitate optimal agency functioning when dealing with climate change-related management issues. Overall, results suggest that a host of institutional and policy-oriented (e.g., lack of clear mandate to adapt to climate change), financial and human resource (e.g., inadequate staff and financial resources), informational (e.g., inadequate research and monitoring programs) and contextual barriers (e.g., sufficient regional networks to mitigate potential transboundary impacts) currently challenge the efficient and effective integration of climate change into decision-making and management within agencies working in these regions. The IPA framework proved to be an effective tool to help managers identify and understand agency strengths, areas of concern, redundancies, and areas that warrant the use of limited funds and/or resource re-allocation in order to enhance adaptive capacity and maximize management effectiveness with respect to climate change.

McKee, Edwin H.; Schmauch, Steven W.

1984-01-01

On the basis of a mineral survey, local areas near and within the Andrews Mountain, Mazourka, and Paiute Roadless Areas, California have probable and substantiated mineral-resource potential. The principal metallic mineral resources in these roadless areas are gold, copper, and silver with lead, zinc, and tungsten, as lesser resources. A zone of probable resource potential for talc, graphite, and marble is identified in the Mazourka Roadless Area. Metallic mineralization occurs mostly in vein deposits in silicic and carbonate metasedimentary rocks peripheral to Mesozoic plutons and locally in granitic rocks as well. There is little promise for the occurrence of fossil fuel resources in the roadless areas.

Looking Down Under for a Circular Economy of Indium.

PubMed

Werner, Tim T; Ciacci, Luca; Mudd, Gavin Mark; Reck, Barbara K; Northey, Stephen Alan

2018-02-20

Indium is a specialty metal crucial for modern technology, yet it is potentially critical due to its byproduct status in mining. Measures to reduce its criticality typically focus on improving its recycling efficiency at end-of-life. This study quantifies primary and secondary indium resources ("stocks") for Australia through a dynamic material-flow analysis. It is based on detailed assessments of indium mineral resources hosted in lead-zinc and copper deposits, respective mining activities from 1844 to 2013, and the trade of indium-containing products from 1988 to 2015. The results show that Australia's indium stocks are substantial, estimated at 46.2 kt in mineral resources and an additional 14.7 kt in mine wastes. Australian mineral resources alone could meet global demand (∼0.8 kt/year) for more than five decades. Discarded material from post-consumer products, instead, is negligible (43 t). This suggests that the resilience of Australia's indium supply can best be increased through efficiency gains in mining (such as introducing domestic indium refining capacity) rather than at the end of the product life. These findings likely also apply to other specialty metals, such as gallium or germanium, and other resource-dominated countries. Finally, the results illustrate that national circular economy strategies can differ substantially.

Royle, Jane; Oliver, Sandy

2004-01-01

This study aims to describe a cycle of development leading to sustainable methods for involving consumers in the management of a program commissioning health technology assessment. Staff time was dedicated to developing procedures for recruiting and briefing consumers to participate in prioritizing, commissioning, and reporting research. Resources and support were developed in light of early feedback from consumers and those working with them. These were piloted and amended before being used routinely. Over 4 years, procedures and resources have been developed to support six consumers attending seven to eight prioritization meetings a year; thirty to forty-five consumers each year commenting on research need for particular topics; thirty consumers a year commenting on research proposals, and twenty a year commenting on research reports. The procedures include clear job descriptions, induction and development days, clear briefing materials, payment for substantial tasks, and regularly seeking feedback to improve procedures. Explicit, inclusive, and reproducible methods for supporting consumer involvement that satisfy National Health Service policy recommendations for involving consumers in research require dedicated staff time to support a cycle of organizational development.

"Talkin' about a revolution": How electronic health records can facilitate the scale-up of HIV care and treatment and catalyze primary care in resource-constrained settings.

2009-11-01

Health care for patients with HIV infection in developing countries has increased substantially in response to major international funding. Scaling up treatment programs requires timely data on the type, quantity, and quality of care being provided. Increasingly, such programs are turning to electronic health records (EHRs) to provide these data. We describe how a medical school in the United States and another in Kenya collaborated to develop and implement an EHR in a large HIV/AIDS care program in western Kenya. These data were used to manage patients, providers, and the program itself as it grew to encompass 18 sites serving more than 90,000 patients. Lessons learned have been applicable beyond HIV/AIDS to include primary care, chronic disease management, and community-based health screening and disease prevention programs. EHRs will be key to providing the highest possible quality of care for the funds developing countries can commit to health care. Public, private, and academic partnerships can facilitate the development and implementation of EHRs in resource-constrained settings.

Linking Environmental Research and Practice: Lessons From The Integration of Climate Science and Water Management in the Western United States

2015-12-01

Efforts to better connect scientific research with people and organizations involved in environmental decision making are receiving increased interest and attention. Some of the challenges we currently face, however—including complex questions associated with climate change—present unique challenges because of their scale and scope. Focused research on the intersections between environment and society has provided substantial insight into dynamics of large-scale environmental change and the related impacts on people, natural resources, and ecosystems, yet our ability to connect this research to real-world decision making remains limited. Addressing these complex environmental problems requires broad cooperation between scientists and those who may apply research results in decision making, but there are few templates for guiding the growing number of scientists and practitioners now engaging in this kind of cooperative work. This presentation will offer a set of heuristics for carrying out collaborative work between scientists and practitioners. These heuristics were derived from research that examined the direct experiences of water resources professionals and climate researchers who have been working to integrate science and practice.

Characterization of wind power resource and its intermittency

NASA Astrophysics Data System (ADS)

Gunturu, U. B.; Schlosser, C. A.

2011-12-01

Wind resource in the continental and offshore United States has been calculated and characterized using metrics that describe - apart from abundance - its availability, persistence and intermittency. The Modern Era Retrospective-Analysis for Research and Applications (MERRA) boundary layer flux data has been used to construct wind power density profiles at 50, 80, 100 and 120 m turbine hub heights. The wind power density estimates at 50 m are qualitatively similar to those in the US wind atlas developed by the National Renewable Energy Laboratory (NREL), but quantitatively a class less in some regions, but are within the limits of uncertainty. We also show that for long tailed distributions like those of the wind power density, the mean is an overestimation and median is a more robust metric for summary representation of wind power resource.Generally speaking, the largest and most available wind power density resources are found in off-shore regions of the Atlantic and Pacific coastline, and the largest on-shore resource potential lies in the central United States. However, the intermittency and widespread synchronicity of on-shore wind power density are substantial, and highlights areas where considerable back-up generation technologies will be required. Generation-duration curves are also presented for the independent systems operator (ISO) zones of the U.S. to highlight the regions with the largest capacity factor (MISO, ERCOT, and SWPP) as well as the periods and extent to which all ISOs contain no wind power and the potential benefits of aggregation on wind power intermittency in each region. The impact of raising the wind turbine hub height on metrics of abundance, persistence, variability and intermittency is analyzed. There is a general increase in availability and abundance of wind resource but there is also an increase in intermittency with respect to a 'usable wind power' crossing level in low resource regions. A similar perspective of wind resource for other regions of the world such as, Europe, India and China is also summarized and notable features highlighted.

Multimorbidity in chronic disease: impact on health care resources and costs

PubMed Central

McPhail, Steven M

2016-01-01

Effective and resource-efficient long-term management of multimorbidity is one of the greatest health-related challenges facing patients, health professionals, and society more broadly. The purpose of this review was to provide a synthesis of literature examining multimorbidity and resource utilization, including implications for cost-effectiveness estimates and resource allocation decision making. In summary, previous literature has reported substantially greater, near exponential, increases in health care costs and resource utilization when additional chronic comorbid conditions are present. Increased health care costs have been linked to elevated rates of primary care and specialist physician occasions of service, medication use, emergency department presentations, and hospital admissions (both frequency of admissions and bed days occupied). There is currently a paucity of cost-effectiveness information for chronic disease interventions originating from patient samples with multimorbidity. The scarcity of robust economic evaluations in the field represents a considerable challenge for resource allocation decision making intended to reduce the burden of multimorbidity in resource-constrained health care systems. Nonetheless, the few cost-effectiveness studies that are available provide valuable insight into the potential positive and cost-effective impact that interventions may have among patients with multiple comorbidities. These studies also highlight some of the pragmatic and methodological challenges underlying the conduct of economic evaluations among people who may have advanced age, frailty, and disadvantageous socioeconomic circumstances, and where long-term follow-up may be required to directly observe sustained and measurable health and quality of life benefits. Research in the field has indicated that the impact of multimorbidity on health care costs and resources will likely differ across health systems, regions, disease combinations, and person-specific factors (including social disadvantage and age), which represent important considerations for health service planning. Important priorities for research include economic evaluations of interventions, services, or health system approaches that can remediate the burden of multimorbidity in safe and cost-effective ways.

Technical support for Life Sciences communities on a production grid infrastructure.

2012-01-01

Production operation of large distributed computing infrastructures (DCI) still requires a lot of human intervention to reach acceptable quality of service. This may be achievable for scientific communities with solid IT support, but it remains a show-stopper for others. Some application execution environments are used to hide runtime technical issues from end users. But they mostly aim at fault-tolerance rather than incident resolution, and their operation still requires substantial manpower. A longer-term support activity is thus needed to ensure sustained quality of service for Virtual Organisations (VO). This paper describes how the biomed VO has addressed this challenge by setting up a technical support team. Its organisation, tooling, daily tasks, and procedures are described. Results are shown in terms of resource usage by end users, amount of reported incidents, and developed software tools. Based on our experience, we suggest ways to measure the impact of the technical support, perspectives to decrease its human cost and make it more community-specific.

Natural thorium resources and recovery: Options and impacts

Ault, Timothy; Van Gosen, Bradley S.; Krahn, Steven; Croff, Allen

2016-01-01

This paper reviews the front end of the thorium fuel cycle, including the extent and variety of thorium deposits, the potential sources of thorium production, and the physical and chemical technologies required to isolate and purify thorium. Thorium is frequently found within rare earth element–bearing minerals that exist in diverse types of mineral deposits, often in conjunction with other minerals mined for their commercial value. It may be possible to recover substantial quantities of thorium as a by-product from active titanium, uranium, tin, iron, and rare earth mines. Incremental physical and chemical processing is required to obtain a purified thorium product from thorium minerals, but documented experience with these processes is extensive, and incorporating thorium recovery should not be overly challenging. The anticipated environmental impacts of by-product thorium recovery are small relative to those of uranium recovery since existing mining infrastructure utilization avoids the opening and operation of new mines and thorium recovery removes radionuclides from the mining tailings.

Optimizing Resources for Trustworthiness and Scientific Impact of Domain Repositories

NASA Astrophysics Data System (ADS)

Lehnert, K.

2017-12-01

Domain repositories, i.e. data archives tied to specific scientific communities, are widely recognized and trusted by their user communities for ensuring a high level of data quality, enhancing data value, access, and reuse through a unique combination of disciplinary and digital curation expertise. Their data services are guided by the practices and values of the specific community they serve and designed to support the advancement of their science. Domain repositories need to meet user expectations for scientific utility in order to be successful, but they also need to fulfill the requirements for trustworthy repository services to be acknowledged by scientists, funders, and publishers as a reliable facility that curates and preserves data following international standards. Domain repositories therefore need to carefully plan and balance investments to optimize the scientific impact of their data services and user satisfaction on the one hand, while maintaining a reliable and robust operation of the repository infrastructure on the other hand. Staying abreast of evolving repository standards to certify as a trustworthy repository and conducting a regular self-assessment and certification alone requires resources that compete with the demands for improving data holdings or usability of systems. The Interdisciplinary Earth Data Alliance (IEDA), a data facility funded by the US National Science Foundation, operates repositories for geochemical, marine Geoscience, and Antarctic research data, while also maintaining data products (global syntheses) and data visualization and analysis tools that are of high value for the science community and have demonstrated considerable scientific impact. Balancing the investments in the growth and utility of the syntheses with resources required for certifcation of IEDA's repository services has been challenging, and a major self-assessment effort has been difficult to accommodate. IEDA is exploring a partnership model to share generic repository functions (e.g. metadata registration, long-term archiving) with other repositories. This could substantially reduce the effort of certification and allow effort to focus on the domain-specific data curation and value-added services.

Adaptation to ecologically complex environments can provide insights into the evolutionary dynamics and functional constraints encountered by organisms during natural selection. Unlike adaptation to a single limiting resource, adaptation to a new environment with abundant and varied resources can be difficult to achieve by small incremental changes since many mutations are required to achieve even modest gains in fitness. Since changing complex environments are quite common in nature, we investigated how such an epistatic bottleneck can be avoided to allow rapid adaptation. We show that adaptive mutations arise repeatedly in independently evolved populations in the context of greatly increased geneticmore » and phenotypic diversity. We go on to show that weak selection requiring substantial metabolic reprogramming can be readily achieved by mutations in the global response regulator arcA and the stress response regulator rpoS. We identified 46 unique single-nucleotide variants of arcA and 18 mutations in rpoS, nine of which resulted in stop codons or large deletions, suggesting that a subtle modulation of ArcA function and knockouts of rpoS are largely responsible for the metabolic shifts leading to adaptation. These mutations allow a higher order “metabolic selection” that eliminates epistatic bottlenecks, which could occur when many changes would be required. Proteomic and carbohydrate analysis of adapting E. coli populations revealed an up-regulation of enzymes associated with the TCA cycle and amino acid metabolism and an increase in the secretion of putrescine. The overall effect of adaptation across populations is to redirect and efficiently utilize uptake and catabolism of abundant amino acids. Concomitantly, there is a pronounced spread of more ecologically limited strains that results from specialization through metabolic erosion. Remarkably, the global regulators arcA and rpoS can provide a “one-step” mechanism of adaptation to a novel environment, which highlights the importance of global resource management as a powerful strategy to adaptation.« less

To update evidence-based guidelines for the treatment of proximal femoral fractures published in the Journal in 1999. Systematic literature search of MEDLINE, CINAHL and EMBASE from January 1996 to September 2001 and the Cochrane Database of Systematic Reviews (most recent issue searched - Issue 2, 2002). Randomised controlled trials and meta-analyses of all aspects of acute-care hospital treatment and rehabilitation of proximal femoral fractures among subjects aged 50 years and over with proximal femoral fractures not associated with metastatic disease or multiple trauma. All studies were read independently by two reviewers. Reviewers recorded individual study results, and an assessment of study quality and treatment conclusions according to Cochrane Collaboration protocols. If necessary, a third review was performed to reach consensus. 93 new studies were identified and 82 met our inclusion criteria. Recommendations for thromboprophylaxis, anaesthesia, surgical fixation of fractures and nutritional status have been altered to incorporate new evidence. Recommendations have been added regarding postoperative blood transfusion, the management of subtrochanteric fractures, and the type of surgical swabs which should be used. Although there have been few significant changes to the previous recommendations, updating the guidelines has required substantial effort. The common clinical problem of hip fracture should be treated according to the most up-to-date evidence to achieve the best possible outcomes and optimal utilisation of limited resources. Guideline updates also require resourcing.

The recovery of resource value from this stream presents critical challenges in areas of materials identification and recycling process design that demand new green engineering technologies applied together with life cycle assessment and ecological supply chain analysis to create viable plastics-to-plastics supply cycles. The sustainable recovery of potentially high-value engineering plastics streams requires that recyclers either avoid mixing plastic parts or purify later by separating smaller plastic pieces created in volume reduction (shredding) steps. Identification and separation constitute significant barriers in the plastics-to-plastics recycling value proposition. In the present work, we develop a model that accepts randomly arriving electronic products to study scenarios by which a recycler might identify and separate high-value engineering plastics as well as metals. Using discrete eventsimulation,we compare current mixed plastics recovery with spectrochemical plastic resin identification and subsequent sorting. Our results show that limited disassembly with whole-part identification can produce substantial yields in separated streams of recovered engineering thermoplastics. We find that disassembly with identification does not constitute a bottleneck, but rather, with relatively few workers, can be configured to pull the process and thus decrease maximum staging space requirements.

Managing CO{sub 2} emissions in Nigeria

DOE Office of Scientific and Technical Information (OSTI.GOV)

Obioh, I.B.; Oluwole, A.F.; Akeredolu, F.A.

The energy resources in Nigeria are nearly equally divided between fossil fuels and biofuels. The increasing pressure on them, following expected increased population growth, may lead to substantial emissions of carbon into the atmosphere. Additionally agricultural and forestry management practices in vogue are those related to savannah burning and rotational bush fallow systems, which have been clearly implicated as important sources of CO{sub 2} and trace gases. An integrated model for the prediction of future CO{sub 2} emissions based on fossil fuels and biomass fuels requirements, rates of deforestation and other land-use indices is presented. This is further based onmore » trends in population and economic growth up to the year 2025, with a base year in 1988. A coupled carbon cycle-climate model based on the contribution of CO{sub 2} and other trace gases is established from the proportions of integrated global warming effects for a 20-year averaging time using the product of global warming potential (GWP) and total emissions. An energy-technology inventory approach to optimal resources management is used as a tool for establishing the future scope of reducing the CO{sub 2} emissions through improved fossil fuel energy efficiencies. Scenarios for reduction based on gradual to swift shifts from biomass to fossil and renewable fuels are presented together with expected policy options required to effect them.« less

Elliott, J.E.; Stotelmeyer, R.B.

1984-01-01

A mineral survey of the North Absaroka study area in Montana was conducted. The results of this survey indicate that parts of the area are extensively mineralized and that the area has potential for resources of gold, silver, copper, molybdenum, nickel, lead, zinc, platinum-group metals, uranium, iron, manganese, chromium, tungsten, and arsenic. Six areas of probable and substantiated mineral-resource potential were identified. The nature of the geologic terrain indicates that there is little likelihood for occurrence of oil, gas, coal, or geothermal resources.

To assess the effectiveness of crew resource management training and interventions on the quality and quantity of communication during cesarean births in a tertiary academic hospital's labor and birthing services. A prospective pre-post crew resource management training intervention. Tertiary academic hospital in the Western United States. All members of obstetric and neonatal teams that participated in cesarean births. Over a 5-month time period, all obstetric and neonatal staff were required to participate in team training in crew resource management critical language, communication, and team structure. Trained observers collected baseline data (n = 52) for 3 months on the quantity and quality of communications that occurred during cesarean births. Postintervention data (n = 50) were gathered for 3 months after team training. Analysis approach included use of Fisher's exact test, independent-samples t test, and multilevel generalized linear regression models with Poisson distribution. There was a statistically significant increase in quantity and quality of communication from pre- to postintervention assessment for obstetric and neonatal staff. Although the increase in quality was similarly great between both types of teams, increase in quantity was more substantial in obstetric staff. Principles of team communication training shown to be effective in increasing communication among team members in a variety of clinical areas were also effective in improving communication in the labor and birth setting during cesarean births.

A CAM- and starch-deficient mutant of the facultative CAM species Mesembryanthemum crystallinum reconciles sink demands by repartitioning carbon during acclimation to salinity

PubMed Central

Haider, Muhammad Sajjad; Barnes, Jeremy D.; Cushman, John C.; Borland, Anne M.

2012-01-01

In the halophytic species Mesembryanthemum crystallinum, the induction of crassulacean acid metabolism (CAM) by salinity requires a substantial investment of resources in storage carbohydrates to provide substrate for nocturnal CO2 uptake. Acclimation to salinity also requires the synthesis and accumulation of cyclitols as compatible solutes, maintenance of root respiration, and nitrate assimilation. This study assessed the hierarchy and coordination of sinks for carbohydrate in leaves and roots during acclimation to salinity in M. crystallinum. By comparing wild type and a CAM-/starch-deficient mutant of this species, it was sought to determine if other metabolic sinks could compensate for a curtailment in CAM and enable acclimation to salinity. Under salinity, CAM deficiency reduced 24 h photosynthetic carbon gain by >50%. Cyclitols were accumulated to comparable levels in leaves and roots of both the wild type and mutant, but represented only 5% of 24 h carbon balance. Dark respiration of leaves and roots was a stronger sink for carbohydrate in the mutant compared with the wild type and implied higher maintenance costs for the metabolic processes underpinning acclimation to salinity when CAM was curtailed. CAM required the nocturnal mobilization of >70% of primary carbohydrate in the wild type and >85% of carbohydrate in the mutant. The substantial allocation of carbohydrate to CAM limited the export of sugars to roots, and the root:shoot ratio declined under salinity. The data suggest a key role for the vacuole in regulating the supply and demand for carbohydrate over the day/night cycle in the starch-/CAM-deficient mutant. PMID:22219316

Networking Cyberinfrastructure Resources to Support Global, Cross-disciplinary Science

NASA Astrophysics Data System (ADS)

Lehnert, K.; Ramamurthy, M. K.

2016-12-01

Geosciences are globally connected by nature and the grand challenge problems like climate change, ocean circulations, seasonal predictions, impact of volcanic eruptions, etc. all transcend both disciplinary and geographic boundaries, requiring cross-disciplinary and international partnerships. Cross-disciplinary and international collaborations are also needed to unleash the power of cyber- (or e-) infrastructure (CI) by networking globally distributed, multi-disciplinary data, software, and computing resources to accelerate new scientific insights and discoveries. While the promises of a global and cross-disciplinary CI are exhilarating and real, a range of technical, organizational, and social challenges needs to be overcome in order to achieve alignment and linking of operational data systems, software tools, and computing facilities. New modes of collaboration require agreement on and governance of technical standards and best practices, and funding for necessary modifications. This presentation will contribute the perspective of domain-specific data facilities to the discussion of cross-disciplinary and international collaboration in CI development and deployment, in particular those of IEDA (Interdisciplinary Earth Data Alliance) serving the solid Earth sciences and Unidata serving atmospheric sciences. Both facilities are closely involved with the US NSF EarthCube program that aims to network and augment existing Geoscience CI capabilities "to make disciplinary boundaries permeable, nurture and facilitate knowledge sharing, …, and enhance collaborative pursuit of cross-disciplinary research" (EarthCube Strategic Vision), while also collaborating internationally to network domain-specific and cross-disciplinary CI resources. These collaborations are driven by the substantial benefits to the science community, but create challenges, when operational and funding constraints need to be balanced with adjustments to new joint data curation practices and interoperability standards.

Seasonal energy storage system based on hydrogen for self sufficient living

NASA Astrophysics Data System (ADS)

Bielmann, M.; Vogt, U. F.; Zimmermann, M.; Züttel, A.

SELF is a resource independent living and working environment. By on-board renewable electricity generation and storage, it accounts for all aspects of living, such as space heating and cooking as well as providing a purified rainwater supply and wastewater treatment, excluding food supply. Uninterrupted, on-demand energy and water supply are the key challenges. Off-grid renewable power supply fluctuations on daily and seasonal time scales impose production gaps that have to be served by local storage, a function normally fulfilled by the grid. While daily variations only obligate a small storage capacity, requirements for seasonal storage are substantial. The energy supply for SELF is reviewed based on real meteorological data and demand patterns for Zurich, Switzerland. A battery system with propane for cooking serves as a reference for battery-only and hybrid battery/hydrogen systems. In the latter, hydrogen is used for cooking and electricity generation. The analysis shows that hydrogen is ideal for long term bulk energy storage on a seasonal timescale, while batteries are best suited for short term energy storage. Although the efficiency penalty from hydrogen generation is substantial, in off-grid systems, this parameter is tolerable since the harvesting ratio of photovoltaic energy is limited by storage capacity.

Pediatric palliative care and pediatric medical ethics: opportunities and challenges.

PubMed

Feudtner, Chris; Nathanson, Pamela G

2014-02-01

The fields of pediatric palliative care (PPC) and pediatric medical ethics (PME) overlap substantially, owing to a variety of historical, cultural, and social factors. This entwined relationship provides opportunities for leveraging the strong communication skills of both sets of providers, as well as the potential for resource sharing and research collaboration. At the same time, the personal and professional relationships between PPC and PME present challenges, including potential conflict with colleagues, perceived or actual bias toward a palliative care perspective in resolving ethical problems, potential delay or underuse of PME services, and a potential undervaluing of the medical expertise required for PPC consultation. We recommend that these challenges be managed by: (1) clearly defining and communicating clinical roles of PPC and PME staff, (2) developing questions that may prompt PPC and PME teams to request consultation from the other service, (3) developing explicit recusal criteria for PPC providers who also provide PME consultation, (4) ensuring that PPC and PME services remain organizationally distinct, and (5) developing well-defined and broad scopes of practice. Overall, the rich relationship between PPC and PME offers substantial opportunities to better serve patients and families facing difficult decisions.

Alcohol use patterns, problems and policies in Malaysia.

PubMed

Jernigan, D H; Indran, S K

1997-12-01

The roots of Malaysia's drinking patterns lie in the introduction of most forms of alcohol by Europeans. Although Malaysia today has relatively low per capita alcohol consumption, available studies and interviews with alcohol industry officials point to a small segment of the population that drinks heavily and causes and experiences substantial alcohol related-problems. Indians are over-represented in this sub-population, but studies also reveal substantial drinking problems among Chinese and Malays. Government officials categorize alcohol as an Indian problem. The government devotes little resources to monitoring drinking patterns, use or problems; or to preventing, treating or educating the public about alcohol-related problems. Alcohol-producing transnational corporations own shares of all of Malaysia's major alcohol producers. In the face of high alcohol taxes and a ban on broadcast advertising of alcoholic beverages, these companies market alcohol aggressively, making health claims, targeting heavy drinkers and encouraging heavy drinking, employing indirect advertising, and using women in seductive poses and occupations to attract the mostly male drinking population. Monitoring of the country's alcohol problems is greatly needed in order to establish alcohol consumption more clearly as a national health and safety issue, while stronger controls and greater corporate responsibility are required to control alcohol marketing.

New and future heat pump technologies

NASA Astrophysics Data System (ADS)

Creswick, F. A.

It is not possible to say for sure what future heat pumps will look like, but there are some interesting possibilities. In the next five years, we are likely to see US heat pumps with two kinds of innovations: capacity modulation and charge control. Capacity modulation will be accomplished by variable-speed compressor motors. The objective of charge control is to keep the refrigerant charge in the system where it belongs for best performance; there are probably many ways to accomplish this. Charge control will improve efficiency and durability; capacity modulation will further improve efficiency and comfort. The Stirling cycle heat pump has several interesting advantages, but it is farther out in time. At present, we don't know how to make it as efficient as the conventional vapor-compression heat pump. Electric utility people should be aware that major advances are being made in gas-fired heat pumps which could provide strong competition in the future. However, even a gas-fired heat pump has a substantial auxiliary electric power requirement. The resources needed to develop advanced heat pumps are substantial and foreign competition will be intense. It will be important for utilities, manufacturers, and the federal government to work in close cooperation.

Some mechanistic requirements for major transitions

PubMed Central

2016-01-01

Major transitions in nature and human society are accompanied by a substantial change towards higher complexity in the core of the evolving system. New features are established, novel hierarchies emerge, new regulatory mechanisms are required and so on. An obvious way to achieve higher complexity is integration of autonomous elements into new organized systems whereby the previously independent units give up their autonomy at least in part. In this contribution, we reconsider the more than 40 years old hypercycle model and analyse it by the tools of stochastic chemical kinetics. An open system is implemented in the form of a flow reactor. The formation of new dynamically organized units through integration of competitors is identified with transcritical bifurcations. In the stochastic model, the fully organized state is quasi-stationary whereas the unorganized state corresponds to a population with natural selection. The stability of the organized state depends strongly on the number of individual subspecies, n, that have to be integrated: two and three classes of individuals, and , readily form quasi-stationary states. The four-membered deterministic dynamical system, , is stable but in the stochastic approach self-enhancing fluctuations drive it into extinction. In systems with five and more classes of individuals, , the state of cooperation is unstable and the solutions of the deterministic ODEs exhibit large amplitude oscillations. In the stochastic system self-enhancing fluctuations lead to extinction as observed with . Interestingly, cooperative systems in nature are commonly two-membered as shown by numerous examples of binary symbiosis. A few cases of symbiosis of three partners, called three-way symbiosis, have been found and were analysed within the past decade. Four-way symbiosis is rather rare but was reported to occur in fungus-growing ants. The model reported here can be used to illustrate the interplay between competition and cooperation whereby we obtain a hint on the role that resources play in major transitions. Abundance of resources seems to be an indispensable prerequisite of radical innovation that apparently needs substantial investments. Economists often claim that scarcity is driving innovation. Our model sheds some light on this apparent contradiction. In a nutshell, the answer is: scarcity drives optimization and increase in efficiency but abundance is required for radical novelty and the development of new features. This article is part of the themed issue ‘The major synthetic evolutionary transitions’. PMID:27431517

Moving image analysis to the cloud: A case study with a genome-scale tomographic study

NASA Astrophysics Data System (ADS)

Mader, Kevin; Stampanoni, Marco

2016-01-01

Over the last decade, the time required to measure a terabyte of microscopic imaging data has gone from years to minutes. This shift has moved many of the challenges away from experimental design and measurement to scalable storage, organization, and analysis. As many scientists and scientific institutions lack training and competencies in these areas, major bottlenecks have arisen and led to substantial delays and gaps between measurement, understanding, and dissemination. We present in this paper a framework for analyzing large 3D datasets using cloud-based computational and storage resources. We demonstrate its applicability by showing the setup and costs associated with the analysis of a genome-scale study of bone microstructure. We then evaluate the relative advantages and disadvantages associated with local versus cloud infrastructures.

What are providers' reporting requirements for children who witness domestic violence?

PubMed

Zink, Therese; Kamine, Darlene; Musk, Lauren; Sill, Morgan; Field, Valerie; Putnam, Frank

2004-06-01

Each year, 3.3 to 10 million children are exposed to domestic violence/abuse (DV). Providers' reporting obligations for these children are unclear. The child maltreatment statutes available on state's web sites (through August 2003) were reviewed. Only Alaska defines DV in the presence of a child as child abuse within its juvenile code. Within their child abuse definition and reporting statutes, many states include language such as "substantial risk" or "imminent danger" of "physical harm" or "mental injury." Although knowledge of the state law is an important first step, abiding by it may be challenging because most statutes are open to wide interpretation. As a result, providers are encouraged to seek advice from local child maltreatment specialists who understand the local legal interpretations and resources.

Predictive Rate-Distortion for Infinite-Order Markov Processes

NASA Astrophysics Data System (ADS)

Marzen, Sarah E.; Crutchfield, James P.

2016-06-01

Predictive rate-distortion analysis suffers from the curse of dimensionality: clustering arbitrarily long pasts to retain information about arbitrarily long futures requires resources that typically grow exponentially with length. The challenge is compounded for infinite-order Markov processes, since conditioning on finite sequences cannot capture all of their past dependencies. Spectral arguments confirm a popular intuition: algorithms that cluster finite-length sequences fail dramatically when the underlying process has long-range temporal correlations and can fail even for processes generated by finite-memory hidden Markov models. We circumvent the curse of dimensionality in rate-distortion analysis of finite- and infinite-order processes by casting predictive rate-distortion objective functions in terms of the forward- and reverse-time causal states of computational mechanics. Examples demonstrate that the resulting algorithms yield substantial improvements.

The balanced scorecard: an integrative approach to performance evaluation.

PubMed

Oliveira, J

2001-05-01

In addition to strict financial outcomes, healthcare financial managers should assess intangible assets that affect the organization's bottom line, such as clinical processes, staff skills, and patient satisfaction and loyalty. The balanced scorecard, coupled with data-warehousing capabilities, offers a way to measure an organization's performance against its strategic objectives while focusing on building capabilities to achieve these objectives. The balanced scorecard examines performance related to finance, human resources, internal processes, and customers. Because the balanced scorecard requires substantial amounts of data, it is a necessity to establish an organizational data warehouse of clinical, operational, and financial data that can be used in decision support. Because it presents indicators that managers and staff can influence directly by their actions, the balanced-scorecard approach to performance measurement encourages behavioral changes aimed at achieving corporate strategies.

Corporate integrity agreements: making the best of a tough situation.

PubMed

Ramsey, Robert B

2002-03-01

Healthcare providers increasingly are entering into corporate integrity agreements as part of settlements with the Federal government in fraud-and-abuse cases. Providers pursue these settlements to avoid the costs of defending themselves against fraud charges. However, the costs relating to the long-term compliance activity mandated in the settlement's corporate integrity agreement also can be substantial. These costs include significant staff resources that must be devoted to compliance efforts demanded by the agreement and the required engagement of consultants to monitor the organization's compliance. Healthcare financial managers should be familiar with the elements of a typical corporate integrity agreement and understand strategies for negotiating such an agreement. Effective negotiations can help minimize the organization's costs of compliance with the agreement and facilitate its ongoing implementation of the agreement.

The Influence of Boundary Layer Parameters on Interior Noise

NASA Technical Reports Server (NTRS)

Palumbo, Daniel L.; Rocha, Joana

2012-01-01

Predictions of the wall pressure in the turbulent boundary of an aerospace vehicle can differ substantially from measurement due to phenomena that are not well understood. Characterizing the phenomena will require additional testing at considerable cost. Before expending scarce resources, it is desired to quantify the effect of the uncertainty in wall pressure predictions and measurements on structural response and acoustic radiation. A sensitivity analysis is performed on four parameters of the Corcos cross spectrum model: power spectrum, streamwise and cross stream coherence lengths and Mach number. It is found that at lower frequencies where high power levels and long coherence lengths exist, the radiated sound power prediction has up to 7 dB of uncertainty in power spectrum levels with streamwise and cross stream coherence lengths contributing equally to the total.

Physician-workforce and educational planning in Canada: has the pendulum swung too far?

PubMed Central

Ryten, E

1995-01-01

Since the early '80s, and especially since the publication in 1991 of Toward Integrated Medical Resource Policies for Canada (the Barer-Stoddart Report), received wisdom has been that there is an oversupply of physicians in Canada and that medical school enrollment should be cut. In a CMAJ article published July 1, 1994, that described a computer program to forecast the supply and demand of health care resources, Denton, Gafni and Spencer projected a substantial physician surplus in Ontario in the years 2000 and 2010, despite substantial cuts in Ontario medical school enrollment. The author questions the data used in the forecasts and reaches different conclusions. She advances an alternative hypothesis that current medical school admission levels are, in fact, too low.

Astronomy: On the Bleeding Edge of Scholarly Infrastructure

Borgman, Christine; Sands, A.; Wynholds, L. A.

2013-01-01

The infrastructure for scholarship has moved online, making data, articles, papers, journals, catalogs, and other scholarly resources nodes in a deeply interconnected network. Astronomy has led the way on several fronts, developing tools such as ADS to provide unified access to astronomical publications and reaching agreement on a common data file formats such as FITS. Astronomy also was among the first fields to establish open access to substantial amounts of observational data. We report on the first three years of a long-term research project to study knowledge infrastructures in astronomy, funded by the NSF and the Alfred P. Sloan Foundation. Early findings indicate that the availability and use of networked technologies for integrating scholarly resources varies widely within astronomy. Substantial differences arise in the management of data between ground-based and space-based missions and between subfields of astronomy, for example. While large databases such as SDSS and MAST are essential resources for many researchers, much pointed, ground-based observational data exist only on local servers, with minimal curation. Some astronomy data are easily discoverable and usable, but many are not. International coordination activities such as IVOA and distributed access to high-level data products servers such as SIMBAD and NED are enabling further integration of published data. Astronomers are tackling yet more challenges in new forms of publishing data, algorithms, visualizations, and in assuring interoperability with parallel infrastructure efforts in related fields. New issues include data citation, attribution, and provenance. Substantial concerns remain for the long term discoverability, accessibility, usability, and curation of astronomy data and other scholarly resources. The presentation will outline these challenges, how they are being addressed by astronomy and related fields, and identify concerns and accomplishments expressed by the astronomers we have interviewed and observed.

Computational issues in complex water-energy optimization problems: Time scales, parameterizations, objectives and algorithms

Modelling of large-scale hybrid renewable energy systems (HRES) is a challenging task, for which several open computational issues exist. HRES comprise typical components of hydrosystems (reservoirs, boreholes, conveyance networks, hydropower stations, pumps, water demand nodes, etc.), which are dynamically linked with renewables (e.g., wind turbines, solar parks) and energy demand nodes. In such systems, apart from the well-known shortcomings of water resources modelling (nonlinear dynamics, unknown future inflows, large number of variables and constraints, conflicting criteria, etc.), additional complexities and uncertainties arise due to the introduction of energy components and associated fluxes. A major difficulty is the need for coupling two different temporal scales, given that in hydrosystem modeling, monthly simulation steps are typically adopted, yet for a faithful representation of the energy balance (i.e. energy production vs. demand) a much finer resolution (e.g. hourly) is required. Another drawback is the increase of control variables, constraints and objectives, due to the simultaneous modelling of the two parallel fluxes (i.e. water and energy) and their interactions. Finally, since the driving hydrometeorological processes of the integrated system are inherently uncertain, it is often essential to use synthetically generated input time series of large length, in order to assess the system performance in terms of reliability and risk, with satisfactory accuracy. To address these issues, we propose an effective and efficient modeling framework, key objectives of which are: (a) the substantial reduction of control variables, through parsimonious yet consistent parameterizations; (b) the substantial decrease of computational burden of simulation, by linearizing the combined water and energy allocation problem of each individual time step, and solve each local sub-problem through very fast linear network programming algorithms, and (c) the substantial decrease of the required number of function evaluations for detecting the optimal management policy, using an innovative, surrogate-assisted global optimization approach.

Illegal, Unreported and Unregulated (IUU) fishing is a problem for marine resource managers, leading to depletion of fish stocks and negative impacts on marine ecosystems. These problems are particularly evident in regions with weak governance. Countries responsible for sustainable natural resource management in the Southern Ocean have actively worked to reduce IUU fishing in the region over a period of 15 years, leading to a sequence of three distinct peaks of IUU fishing. We reviewed existing public records relating to IUU fishing in the Southern Ocean between 1995-2009 and related this information to the governance capacity of flag states responsible for IUU vessels. IUU operators used a number of methods to adapt to enforcement actions, resulting in reduced risks of detection, apprehension and sanctioning. They changed fishing locations, vessel names and flag states, and ports for offloading IUU catches. There was a significant decrease in the proportion of IUU vessels flagged to CCAMLR countries, and a significant decrease in the average governance index of flag states. Despite a decreasing trend of IUU fishing, further actions are hampered by the regional scope of CCAMLR and the governance capacity of responsible states. This is the first study of long-term change in the modus operandi of IUU fishing operators, illustrating that IUU operators can adapt to enforcement actions and that such dynamics may lead to new problems elsewhere, where countries have a limited capacity. This outsourcing of problems may have similarities to natural resource extraction in other sectors and in other regions. IUU fishing is the result of a number of factors, and effectively addressing this major challenge to sustainable marine resource extraction will likely require a stronger focus on governance. Highly mobile resource extractors with substantial funds are able to adapt to changing regulations by exploiting countries and regions with limited capacity.

AN ANALYSIS OF THE INEQUALITIES BETWEEN THE PUBLIC AND PRIVATE SECTOR IN SOUTH AFRICA.

The full extent of the global burden of surgical disease is largely unknown, however, the scope of the problem is thought to be large. Despite the substantial burden of surgical disease, surgical services are inaccessible to many of those who need them most. There are disparities between public and private sectors in South Africa, which compounds inequitable access to surgical care. This study involved a descriptive analysis of surgical resources and included the total number of hospitals, of hospital beds, the number of surgical beds, the number of general surgeons (specialist and non-specialist), and the number of functional operating theatres in South Africa. A comparison was performed between the public and private sectors. Hospitals were contacted during the period from the 1st October 2014 until the 31st of December 2014. Surgical resources were concentrated in metropolitan areas of urban provinces. There were striking differences between the public and private sectors, where private resources were comparable to those available in high income countries (HICs). Improving access to surgical services in lower middle income countries (LMICs) requires addressing gaps between the public and private sector regarding infrastructure, personnel, as well as equipment. South Africa is unique in that although it is classified as an upper middle income country (UMIC), is comprises of two sectors; a public sector which has resources similar to other LMICs, and a private sector which has resources similar to HICs. These data identified disparities between geographic regions which may be contributing to ongoing inequity in South Africa, and by doing so allows for evidence-based planning towards improving surgical infrastructure and workforce.

In January 2006 the Smith River Rancheria (SRR), located in Smith River, California, contracted with the team of Strategic Energy Solutions (SES) and Evergreen NRG to conduct a study for the community. The objective of the study was to identify renewable generation opportunities that would facilitate Rancheria energy independence through SRR owned and operated power projects. These generation facilities were to be located either on or near the reservation. Specifically, the Rancheria was interested in the viability of generating electric power using biomass and wind fuel resources. Initial research identified that a very small portion of the community's energy couldmore » be offset by renewable energy generation due to the low solar resource in this area, and the lack of significant wind or biomass resources on or near reservation land. Some larger projects were identified which offered little or no benefit to the Rancheria. As a result, the scope of this study was changed in October 2006 to focus on energy efficiency opportunities for key reservation facilities, with a continued analysis of smaller renewable energy opportunities within reservation boundaries. The consulting team initially performed a resource analysis for biomass and solar generation opportunities in the region of the Rancheria. It was quickly concluded that none of these options would yield renewable power for the Rancheria at costs competitive with current utility sources, and that any larger installations would require substantial funding that may not be available. Having made these conclusions early on, the study effort was redirected and the team investigated each of the major Rancheria buildings to look for solar, wind and conservation opportunities. The buildings were audited for energy use and the roof areas were examined for exposure of solar radiation. Wind resources were also investigated to determine if smaller wind turbines would offer power generation at a reasonable cost.« less

A systematic review and overview of health economic evaluations of emergency laparotomy.

PubMed

Bampoe, Sohail; Odor, Peter M; Ramani Moonesinghe, S; Dickinson, Matthew

2017-01-01

Little is known about the economic impact of emergency laparotomy (EL) surgery in healthcare systems around the world. The aim of this systematic review is to describe the primary resource utilisation, healthcare economic and societal costs of EL in adults in different countries. MEDLINE, EMBASE, ISI Web of Knowledge, Cochrane Central Register Controlled Trials, Cochrane Database of Systematic Reviews and CINAHL were searched for full and partial economic analyses of EL published between 1 January 1991 and 31 December 2015. Quality of studies was assessed using the Consensus on Health Economic Criteria (CHEC) checklist. Sixteen studies were included from a range of countries. One study was a full economic analysis. Fifteen studies were partial economic evaluations. These studies revealed that emergency abdominal surgery is expensive compared to similar elective surgery when comparing primary resource utilisation costs, with an important societal impact. Most contemporaneous studies indicate that in-hospital costs for EL are in excess of US$10,000 per patient episode, rising substantially when societal costs are considered. EL is a high-risk and costly procedure with a disproportionate financial burden for healthcare providers, relative to national funding provisions and wider societal cost impact. There is substantial heterogeneity in the methodologies and quality of published economic evaluations of EL; therefore, the true economic costs of EL are yet to be fully defined. Future research should focus on developing strategies to embed health economic evaluations within national programmes aiming to improve EL care, including developing the required measures and infrastructure. Emergency laparotomy is expensive, with a significant cost burden to healthcare and systems and society worldwide. Novel strategies for reducing this econmic burden should urgently be explored if greater access to this type of surgery is to be pursued as a global health target.

Over 72% of Americans use online health information to assist in health care decision-making. Previous studies of lymphedema literature have focused only on reading level of patient-oriented materials online. Findings indicate they are too advanced for most patients to comprehend. This, more comprehensive study, expands the previous analysis to include critical elements of health materials beyond readability using assessment tools to report on the complexity and density of data as well as text design, vocabulary, and organization. The top 10 highest ranked websites on lymphedema were identified using the most popular search engine (Google). Website content was analyzed for readability, complexity, and suitability using Simple Measure of Gobbledygook, PMOSE/iKIRSCH, and Suitability Assessment of Materials (SAM), respectively. PMOSE/iKIRSCH and SAM were performed by two independent raters. Fleiss' kappa score was calculated to ensure inter-rater reliability. Online lymphedema literature had a reading grade level of 14.0 (SMOG). Overall complexity score was 6.7 (PMOSE/iKIRSCH) corresponding to "low" complexity and requiring a 8th-12th grade education. Fleiss' kappa score was 80% (P = 0.04, "substantial" agreement). Overall suitability score was 45% (SAM) correlating to the lowest level of "adequate" suitability. Fleiss' kappa score was 76% (P = 0.06, "substantial" agreement). Online resources for lymphedema are above the recommended levels for readability and complexity. The suitability level is barely adequate for the intended audience. Overall, these materials are too sophisticated for the average American adult, whose literacy skills are well documented. Further efforts to revise these materials are needed to improve patient comprehension and understanding. Copyright © 2017 Elsevier Inc. All rights reserved.

Direct collapse to supermassive black hole seeds: comparing the AMR and SPH approaches.

PubMed

Luo, Yang; Nagamine, Kentaro; Shlosman, Isaac

2016-07-01

We provide detailed comparison between the adaptive mesh refinement (AMR) code enzo-2.4 and the smoothed particle hydrodynamics (SPH)/ N -body code gadget-3 in the context of isolated or cosmological direct baryonic collapse within dark matter (DM) haloes to form supermassive black holes. Gas flow is examined by following evolution of basic parameters of accretion flows. Both codes show an overall agreement in the general features of the collapse; however, many subtle differences exist. For isolated models, the codes increase their spatial and mass resolutions at different pace, which leads to substantially earlier collapse in SPH than in AMR cases due to higher gravitational resolution in gadget-3. In cosmological runs, the AMR develops a slightly higher baryonic resolution than SPH during halo growth via cold accretion permeated by mergers. Still, both codes agree in the build-up of DM and baryonic structures. However, with the onset of collapse, this difference in mass and spatial resolution is amplified, so evolution of SPH models begins to lag behind. Such a delay can have effect on formation/destruction rate of H 2 due to UV background, and on basic properties of host haloes. Finally, isolated non-cosmological models in spinning haloes, with spin parameter λ ∼ 0.01-0.07, show delayed collapse for greater λ, but pace of this increase is faster for AMR. Within our simulation set-up, gadget-3 requires significantly larger computational resources than enzo-2.4 during collapse, and needs similar resources, during the pre-collapse, cosmological structure formation phase. Yet it benefits from substantially higher gravitational force and hydrodynamic resolutions, except at the end of collapse.

Diggles, Michael F.; Rains, Richard L.

1984-01-01

The mineral survey of the Blanco Mountain and Black Canyon Roadless Areas, California indicated that areas of probable and substantiated mineral-resource potential exist only in the Black Canyon Roadless Area. Gold with moderate amounts of lead, silver, zinc, and tungsten, occurs in vein deposits and in tactite. The nature of the geological terrain indicates little likelihood for the occurrence of energy resources in the roadless areas. Detailed geologic mapping might better define the extent of gold mineralization. Detailed stream-sediment sampling and analysis of heavy-mineral concentrations could better define tungsten resource potential.

The Yampa River basin, Colorado and Wyoming : a preview to expanded coal-resource development and its impacts on regional water resources

1979-01-01

Expanded coal production and conversion in the Yampa River basin , Colorado and Wyoming, may have substantial impacts on water resources, environmental amenities, and socioeconomic conditions. Preliminary results of a 3-year basin assessment by the U.S. Geological Survey are given for evaluation of surface- and ground-water resources using available data, modeling analysis of waste-load capacity of a Yampa River reach affected by municipal wastewater-treatment plant effluents, and semiquantitative descriptions of ambient air- and water-quality conditions. Aspects discussed are possible constraints on proposed development due to basin compacts and laws regulating water resources, possible changes in environmental-control regulations, and policies on energy-resource leasing and land use that will influence regional economic development.

Financial development and oil resource abundance-growth relations: evidence from panel data.

PubMed

Law, Siong Hook; Moradbeigi, Maryam

2017-10-01

This study investigates whether financial development dampens the negative impact of oil resource abundance on economic growth. Because of substantial cross-sectional dependence in our data, which contain a core sample of 63 oil-producing countries from 1980 through 2010, we use the common correlated effect mean group (CCEMG) estimator to account for the high degree of heterogeneity and drop the outlier countries. The empirical results reveal that oil resource abundance affects the growth rate in output contingent on the degree of development in financial markets. More developed financial markets can channel the revenues from oil into more productive activities and thus offset the negative effects of oil resource abundance on economic growth. Thus, better financial development can reverse resource curse or enhance resource blessing in oil-rich economies.

Intelligent infrastructure for sustainable potable water: a roundtable for emerging transnational research and technology development needs.

2003-12-01

Recent commercial and residential development have substantially impacted the fluxes and quality of water that recharge the aquifers and discharges to streams, lakes and wetlands and, ultimately, is recycled for potable use. Whereas the contaminant sources may be varied in scope and composition, these issues of urban water sustainability are of public health concern at all levels of economic development worldwide, and require cheap and innovative environmental sensing capabilities and interactive monitoring networks, as well as tailored distributed water treatment technologies. To address this need, a roundtable was organized to explore the potential role of advances in biotechnology and bioengineering to aid in developing causative relationships between spatial and temporal changes in urbanization patterns and groundwater and surface water quality parameters, and to address aspects of socioeconomic constraints in implementing sustainable exploitation of water resources. An interactive framework for quantitative analysis of the coupling between human and natural systems requires integrating information derived from online and offline point measurements with Geographic Information Systems (GIS)-based remote sensing imagery analysis, groundwater-surface water hydrologic fluxes and water quality data to assess the vulnerability of potable water supplies. Spatially referenced data to inform uncertainty-based dynamic models can be used to rank watershed-specific stressors and receptors to guide researchers and policymakers in the development of targeted sensing and monitoring technologies, as well as tailored control measures for risk mitigation of potable water from microbial and chemical environmental contamination. The enabling technologies encompass: (i) distributed sensing approaches for microbial and chemical contamination (e.g. pathogens, endocrine disruptors); (ii) distributed application-specific, and infrastructure-adaptive water treatment systems; (iii) geostatistical integration of monitoring data and GIS layers; and (iv) systems analysis of microbial and chemical proliferation in distribution systems. This operational framework is aimed at technology implementation while maximizing economic and public health benefits. The outcomes of the roundtable will further research agendas in information technology-based monitoring infrastructure development, integration of processes and spatial analysis, as well as in new educational and training platforms for students, practitioners and regulators. The potential for technology diffusion to emerging economies with limited financial resources is substantial.

Review of Statistical Methods for Analysing Healthcare Resources and Costs

Mihaylova, Borislava; Briggs, Andrew; O'Hagan, Anthony; Thompson, Simon G

2011-01-01

We review statistical methods for analysing healthcare resource use and costs, their ability to address skewness, excess zeros, multimodality and heavy right tails, and their ease for general use. We aim to provide guidance on analysing resource use and costs focusing on randomised trials, although methods often have wider applicability. Twelve broad categories of methods were identified: (I) methods based on the normal distribution, (II) methods following transformation of data, (III) single-distribution generalized linear models (GLMs), (IV) parametric models based on skewed distributions outside the GLM family, (V) models based on mixtures of parametric distributions, (VI) two (or multi)-part and Tobit models, (VII) survival methods, (VIII) non-parametric methods, (IX) methods based on truncation or trimming of data, (X) data components models, (XI) methods based on averaging across models, and (XII) Markov chain methods. Based on this review, our recommendations are that, first, simple methods are preferred in large samples where the near-normality of sample means is assured. Second, in somewhat smaller samples, relatively simple methods, able to deal with one or two of above data characteristics, may be preferable but checking sensitivity to assumptions is necessary. Finally, some more complex methods hold promise, but are relatively untried; their implementation requires substantial expertise and they are not currently recommended for wider applied work.

Geothermal resources of California sedimentary basins

Williams, C.F.; Grubb, F.V.; Galanis, S.P.

2004-01-01

The 2004 Department of Energy (DOE) Strategic Plan for geothermal energy calls for expanding the geothermal resource base of the United States to 40,000 MW of electric power generating potential. This will require advances in technologies for exploiting unconventional geothermal resources, including Enhanced Geothermal Systems (EGS) and geopressured geothermal. An investigation of thermal conditions in California sedimentary basins through new temperature and heat flow measurements reveals significant geothermal potential in some areas. In many of the basins, the combined cooling effects of recent tectonic and sedimentary processes result in relatively low (<60 mW/m2) heat flow and geothermal gradients. For example, temperatures in the upper 3 km of San Joaquin, Sacramento and Ventura basins are typically less than 125??C and do not reach 200??c by 5 km. By contrast, in the Cuyama, Santa Maria and western Los Angeles basins, heat flow exceeds 80 mW/m2 and temperatures near or above 200??C occur at 4 to 5 km depth, which represents thermal conditions equivalent to or hotter than those encountered at the Soultz EGS geothermal site in Europe. Although the extractable geothermal energy contained in these basins is not large relative to the major California producing geothermal fields at The Geysers or Salton Sea, the collocation in the Los Angeles basin of a substantial petroleum extraction infrastructure and a major metropolitan area may make it attractive for eventual geothermal development as EGS technology matures.

Data identification for improving gene network inference using computational algebra.

PubMed

Dimitrova, Elena; Stigler, Brandilyn

2014-11-01

Identification of models of gene regulatory networks is sensitive to the amount of data used as input. Considering the substantial costs in conducting experiments, it is of value to have an estimate of the amount of data required to infer the network structure. To minimize wasted resources, it is also beneficial to know which data are necessary to identify the network. Knowledge of the data and knowledge of the terms in polynomial models are often required a priori in model identification. In applications, it is unlikely that the structure of a polynomial model will be known, which may force data sets to be unnecessarily large in order to identify a model. Furthermore, none of the known results provides any strategy for constructing data sets to uniquely identify a model. We provide a specialization of an existing criterion for deciding when a set of data points identifies a minimal polynomial model when its monomial terms have been specified. Then, we relax the requirement of the knowledge of the monomials and present results for model identification given only the data. Finally, we present a method for constructing data sets that identify minimal polynomial models.

A mineral-resource survey determined that coal is the most important mineral resource in the Cheat Mountain Roadless Area, West Virginia. It is tentatively ranked as high-volatile A to medium-volatile bituminous similar to coal in nearby mining areas, and is primarily of coking quality. Demonstrated coal resources are estimated to total about 11. 6 million short tons in beds more than 28 in. thick in areas of substantiated resource potential and an additional 32. 7 million short tons in beds between 14 and 28 in. thick have been identified. Limestone, shale, clay, and sandstone occur in the area but these commodities are readily available outside the roadless area. Available information suggests little promise for the occurrence of metallic mineral or other energy resources in the area.

Historical nectar assessment reveals the fall and rise of floral resources in Britain.

2016-02-04

There is considerable concern over declines in insect pollinator communities and potential impacts on the pollination of crops and wildflowers. Among the multiple pressures facing pollinators, decreasing floral resources due to habitat loss and degradation has been suggested as a key contributing factor. However, a lack of quantitative data has hampered testing for historical changes in floral resources. Here we show that overall floral rewards can be estimated at a national scale by combining vegetation surveys and direct nectar measurements. We find evidence for substantial losses in nectar resources in England and Wales between the 1930s and 1970s; however, total nectar provision in Great Britain as a whole had stabilized by 1978, and increased from 1998 to 2007. These findings concur with trends in pollinator diversity, which declined in the mid-twentieth century but stabilized more recently. The diversity of nectar sources declined from 1978 to 1990 and thereafter in some habitats, with four plant species accounting for over 50% of national nectar provision in 2007. Calcareous grassland, broadleaved woodland and neutral grassland are the habitats that produce the greatest amount of nectar per unit area from the most diverse sources, whereas arable land is the poorest with respect to amount of nectar per unit area and diversity of nectar sources. Although agri-environment schemes add resources to arable landscapes, their national contribution is low. Owing to their large area, improved grasslands could add substantially to national nectar provision if they were managed to increase floral resource provision. This national-scale assessment of floral resource provision affords new insights into the links between plant and pollinator declines, and offers considerable opportunities for conservation.

Participatory Water Resources Modeling in a Water-Scarce Basin (Rio Sonora, Mexico) Reveals Uncertainty in Decision-Making

NASA Astrophysics Data System (ADS)

Mayer, A. S.; Vivoni, E. R.; Halvorsen, K. E.; Kossak, D.

2014-12-01

The Rio Sonora Basin (RSB) in northwest Mexico has a semi-arid and highly variable climate along with urban and agricultural pressures on water resources. Three participatory modeling workshops were held in the RSB in spring 2013. A model of the water resources system, consisting of a watershed hydrology model, a model of the water infrastructure, and groundwater models, was developed deliberatively in the workshops, along with scenarios of future climate and development. Participants were asked to design water resources management strategies by choosing from a range of supply augmentation and demand reduction measures associated with water conservation. Participants assessed water supply reliability, measured as the average daily supply divided by daily demand for historical and future periods, by probing with the climate and development scenarios. Pre- and post-workshop-surveys were developed and administered, based on conceptual models of workshop participants' beliefs regarding modeling and local water resources. The survey results indicate that participants believed their modeling abilities increased and beliefs in the utility of models increased as a result of the workshops. The selected water resources strategies varied widely among participants. Wastewater reuse for industry and aquifer recharge were popular options, but significant numbers of participants thought that inter-basin transfers and desalination were viable. The majority of participants indicated that substantial increases in agricultural water efficiency could be achieved. On average, participants chose strategies that produce reliabilities over the historical and future periods of 95%, but more than 20% of participants were apparently satisfied with reliabilities lower than 80%. The wide range of strategies chosen and associated reliabilities indicate that there is a substantial degree of uncertainty in how future water resources decisions could be made in the region.

Much of the roadless area has probable and substantiated potential for resources of gold, silver, molybdenum, and tungsten. The nature of the geologic terrain indicates that there is little promise for the occurrence of coal, oil, gas, or geothermal resources. Detailed geologic and geochemical studies are suggested to delineate exploration targets that could be tested by drilling.

2015-12-01

Energy, water and food are critical resources for sustaining social development and human lives; human beings cannot survive without any one of them. Energy crises, water shortages and food security are crucial worldwide problems. The nexus of energy, water and food has received more and more attention in the past decade. Energy, water and food are closely interrelated; water is required in energy development such as electricity generation; energy is indispensable for collecting, treating, and transporting water; both energy and water are crucial inputs for food production. Changes of either of them can lead to substantial impacts on other two resources, and vice versa. Effective decisions should be based on thorough research efforts for better understanding of their complex nexus. Rapid increase of population has significantly intensified the pressures on energy, water and food. Addressing and quantifying their interactive relationships are important for making robust and cost-effective strategies for managing the three resources simultaneously. In addition, greenhouse gases (GHGs) are emitted in energy, water, food production, consequently making contributions to growing climate change. Reflecting environmental impacts of GHGs is also desired (especially, on the quality and quantity of fresh water resources). Thus, a socio-economic model is developed in this study to quantitatively address the complex connections among energy, water and food production. A synthetic problem is proposed to demonstrate the model's applicability and feasibility. Preliminary results related to integrated decisions on energy supply management, water use planning, electricity generation planning, energy facility capacity expansion, food production, and associated GHG emission control are generated for providing cost-effective supports for decision makers.

Contaminated sites in the United States undergo remediation and restoration through regulatory programs that lead the 2 processes through independent but often parallel pathways with different objectives. The objective of remediation is to reduce risk to human health and the environment, whereas that of restoration is to restore injured resources and compensate the public for lost use of the services that natural resources provide. More complex sites, such as those associated with large river systems and urban waterways, have resulted in increasingly larger-scale ecological risk assessments (ERAs) and natural resource damage assessments (NRDAs) that take many years and involve diverse practitioners including scientists, economists, and engineers. Substantial levels of effort are now frequently required, creating a need for more efficient and cost-effective approaches to data collection, analyses, and assessments. Because there are commonalities in the data needs between ERAs and NRDAs, coordination of the design and implementation of site-specific studies that meet the needs of both programs could result in increased efficiency and lower costs. The Association for Environmental Health and Sciences Foundation convened a panel of environmental practitioners from industry, consulting, and regulatory bodies to examine the benefits and challenges associated with coordinating ERA and NRDA activities in the context of a broad range of regulatory programs. This brief communication presents the opinions and conclusions of the panelists on these issues and reports 2 case studies for which coordinated ERA and NRDA activities produced a positive outcome.

1. Declining abundances of forage fish and the introduction and establishment of non-indigenous species have the potential to substantially alter resource and habitat exploitation by top predators in large lakes. 2. We measured stable isotopes of carbon (δ13C) and nitrogen (δ15N) in field-collected and archived samples of Lake Ontario lake trout (Salvelinus namaycush) and five species of prey fish and compared current trophic relationships of this top predator with historical samples. 3. Relationships between δ15N and lake trout age were temporally consistent throughout Lake Ontario and confirmed the role of lake trout as a top predator in this food web. However, δ13C values for age classes of lake trout collected in 2008 ranged from 1.0 to 3.9‰ higher than those reported for the population sampled in 1992. 4. Isotope mixing models predicted that these changes in resource assimilation were owing to the replacement of rainbow smelt (Osmerus mordax) by round goby (Neogobius melanostomus) in lake trout diet and increased reliance on carbon resources derived from nearshore production. This contrasts with the historical situation in Lake Ontario where δ13C values of the lake trout population were dominated by a reliance on offshore carbon production. 5. These results indicate a reduced capacity of the Lake Ontario offshore food web to support the energetic requirements of lake trout and that this top predator has become increasingly reliant on prey resources that are derived from nearshore carbon pathways.

The Sarcoma Policy Checklist was created by a multidisciplinary expert group to provide policymakers with priority areas to improve care for sarcoma patients. This paper draws on this research, by looking more closely at how France, Germany, Italy, Spain, Sweden and the United Kingdom are addressing each of these priority areas. It aims to highlight key gaps in research, policy and practice, as well as ongoing initiatives that may impact the future care of sarcoma patients in different European countries. A pragmatic review of the published and web-based literature was undertaken. Telephone interviews were conducted in each country with clinical and patient experts to substantiate findings. Research findings were discussed within the expert group and developed into five core policy recommendations. The five identified priority areas were: the development of designated and accredited centres of reference; more professional training; multidisciplinary care; greater incentives for research and innovation; and more rapid access to effective treatments. Most of the countries studied have ongoing initiatives addressing many of these priorities; however, many are in early stages of development, or require additional funding and resources. Gaps in access to quality care are particularly concerning in many of Europe's lower-resourced countries. Equitable access to information, clinical trials, innovative treatments and quality specialist care should be available to all sarcoma patients. Achieving this across Europe will require close collaboration between all stakeholders at both the national and European level.

Estimating Monthly Water Withdrawals, Return Flow, and Consumptive Use in the Great Lakes Basin

Water-resource managers and planners require water-withdrawal, return-flow, and consumptive-use data to understand how anthropogenic (human) water use affects the hydrologic system. Water models like MODFLOW and GSFLOW use calculations and input values (including water-withdrawal and return flow data) to simulate and predict the effects of water use on aquifer and stream conditions. Accurate assessments of consumptive use, interbasin transfer, and areas that are on public supply or sewer are essential in estimating the withdrawal and return-flow data needed for the models. As the applicability of a model to real situations depends on accurate input data, limited or poor water-use data hampers the ability of modelers to simulate and predict hydrologic conditions. Substantial differences exist among the many agencies nationwide that are responsible for compiling water-use data including what data are collected, how the data are organized, how often the data are collected, quality assurance, required level of accuracy, and when data are released to the public. This poster presents water-use information and estimation methods summarized from recent U.S. Geological Survey (USGS) reports with the intent to assist water-resource managers and planners who need estimates of monthly water withdrawals, return flows, and consumptive use. This poster lists references used in Shaffer (2009) for water withdrawals, consumptive use, and return flows. Monthly percent of annual withdrawals and monthly consumptive-use coefficients are used to compute monthly water withdrawals, consumptive use, and return flow for the Great Lakes Basin.

The Family Wellbeing (FWB) program applies culturally appropriate community led empowerment training to enhance the personal development of Aboriginal and Torres Strait Islander people in life skills. This study sought to estimate the economic cost required to deliver the FWB program to a child safety workforce in remote Australian communities. This study was designed as a retrospective cost description taken from the perspective of a non-government child safety agency. The target population were child protection residential care workers aged 24 or older, who worked in safe houses in five remote Indigenous communities and a regional office during the study year (2013). Resource utilization included direct costs (personnel and administrative) and indirect or opportunity costs of participants, regarded as absence from work. The total cost of delivering the FWB program for 66 participants was $182,588 ($2766 per participant), with 45% ($82,995) of costs classified as indirect (i.e., opportunity cost of participants time). Training cost could be further mitigated (∼30%) if offered on-site, in the community. The costs for offering the FWB program to a remotely located workforce were high, but not substantial when compared to the recruitment cost required to substitute a worker in remote settings. An investment of $2766 per participant created an opportunity to improve social and emotional wellbeing of remotely located workforce. This cost study provided policy relevant information by identifying the resources required to transfer the FWB program to other remote locations. It also can be used to support future comparative cost and outcome analyses and add to the evidence base around the cost-effectiveness of empowerment programs. Copyright © 2017 Elsevier Ltd.

The increasing prevalence of end-stage renal disease (ESRD) is an important public health issue due to the high costs of kidney replacement therapies. We examined the impact of ethnicity and other factors in ESRD management and hospitalisation in a multiracial Asian population in the fi rst year after diagnosis. We analysed a prospectively collected database of 168 new ESRD patients from the National University Hospital, Singapore (NUH) in 2005. Univariate and multivariate analyses were performed to assess factors for mortality and hospitalisation. Sixteen patients eventually chose conservative treatment, 102 haemodialysis, 41 peritoneal dialysis and 9 patients underwent kidney transplantation for their long-term treatment. Although more Chinese patients had dialysis plans (56.7% vs 36.8%, P = 0.022), many still required urgent dialysis initiation via catheters (61.3%). These dialysed patients who required urgent treatment had more admissions (3.6 vs 2.6, P = 0.023) and longer length of stay (9.3 days, P = 0.014). Approximately 40 (7.4%) admissions were related to vascular access complications (thromboses, dislodgements and infections), and 15 (2.8%) were for new tunnelled catheter insertions. Deaths were 23.8% in the fi rst year after diagnosis and median survival was 125 days. Age, fi nal treatment modality, type of therapy centre, history of coronary artery disease, left ventricular ejection fraction (LVEF) <50%, and having no plans for dialysis were associated with mortality. The care of ESRD patients requires substantial commitment of healthcare resources particularly in the fi rst year after diagnosis. Steps to reduce urgent initiation of dialysis will help reduce resource utilisation and improve patient outcomes.

Whole-genome and exome sequencing have already proven to be essential and powerful methods to identify genes responsible for simple Mendelian inherited disorders. These methods can be applied to complex disorders as well, and have been adopted as one of the current mainstream approaches in population genetics. These achievements have been made possible by next generation sequencing (NGS) technologies, which require substantial bioinformatics resources to analyze the dense and complex sequence data. The huge analytical burden of data from genome sequencing might be seen as a bottleneck slowing the publication of NGS papers at this time, especially in psychiatric genetics. We review the existing methods for processing NGS data, to place into context the rationale for the design of a computational resource. We describe our method, the Graphical Pipeline for Computational Genomics (GPCG), to perform the computational steps required to analyze NGS data. The GPCG implements flexible workflows for basic sequence alignment, sequence data quality control, single nucleotide polymorphism analysis, copy number variant identification, annotation, and visualization of results. These workflows cover all the analytical steps required for NGS data, from processing the raw reads to variant calling and annotation. The current version of the pipeline is freely available at http://pipeline.loni.ucla.edu. These applications of NGS analysis may gain clinical utility in the near future (e.g., identifying miRNA signatures in diseases) when the bioinformatics approach is made feasible. Taken together, the annotation tools and strategies that have been developed to retrieve information and test hypotheses about the functional role of variants present in the human genome will help to pinpoint the genetic risk factors for psychiatric disorders.

Guideline adaptation and implementation planning: a prospective observational study

PubMed Central

2013-01-01

Background Adaptation of high-quality practice guidelines for local use has been advanced as an efficient means to improve acceptability and applicability of evidence-informed care. In a pan-Canadian study, we examined how cancer care groups adapted pre-existing guidelines to their unique context and began implementation planning. Methods Using a mixed-methods, case-study design, five cases were purposefully sampled from self-identified groups and followed as they used a structured method and resources for guideline adaptation. Cases received the ADAPTE Collaboration toolkit, facilitation, methodological and logistical support, resources and assistance as required. Documentary and primary data collection methods captured individual case experience, including monthly summaries of meeting and field notes, email/telephone correspondence, and project records. Site visits, process audits, interviews, and a final evaluation forum with all cases contributed to a comprehensive account of participant experience. Results Study cases took 12 to >24 months to complete guideline adaptation. Although participants appreciated the structure, most found the ADAPTE method complex and lacking practical aspects. They needed assistance establishing individual guideline mandate and infrastructure, articulating health questions, executing search strategies, appraising evidence, and achieving consensus. Facilitation was described as a multi-faceted process, a team effort, and an essential ingredient for guideline adaptation. While front-line care providers implicitly identified implementation issues during adaptation, they identified a need to add an explicit implementation planning component. Conclusions Guideline adaptation is a positive initial step toward evidence-informed care, but adaptation (vs. ‘de novo’ development) did not meet expectations for reducing time or resource commitments. Undertaking adaptation is as much about the process (engagement and capacity building) as it is about the product (adapted guideline). To adequately address local concerns, cases found it necessary to also search and appraise primary studies, resulting in hybrid (adaptation plus de novo) guideline development strategies that required advanced methodological skills. Adaptation was found to be an action element in the knowledge translation continuum that required integration of an implementation perspective. Accordingly, the adaptation methodology and resources were reformulated and substantially augmented to provide practical assistance to groups not supported by a dedicated guideline panel and to provide more implementation planning support. The resulting framework is called CAN-IMPLEMENT. PMID:23656884

Coal, the principal mineral resource of the Dolly Sods Wilderness, West Virginia is in at least seven beds of low- to medium-volatile bituminous rank. Of these beds, four are of sufficient thickness, quality, and extent to contain demonstrated coal resources which are estimated to total about 15. 5 million short tons in areas of substantiated coal resource potential. A Small-scale development of the coal resources of the Dolly Sods Wilderness has been by several shallow adits which provided fuel for locomotives during early logging operations and by a one truck mine. All mine entries are now abandoned. Peat, shale, clay, and sandstone, occur in the area but because of remoteness of markets and inaccessability they are not classified as resources in this report. Natural gas may occur in rocks underlying the area, but because of a lack of subsurface information an estimate of resource potential has not been made. No evidence of metallic-mineral resources was found during this investigation.

The past decade has brought substantial transition to South Africa. The introduction of democracy in 1994 has yielded important political and socioeconomic transformations affecting millions of people. Here, we explore the impact of institutional and structural changes on the availability and management of fuelwood, a key natural resource in rural South Africa. As in other developing regions, many households depend on natural resources for both sustenance and energy needs. Drawing on qualitative data from 32 interviews, our objective is to describe, from the perspective of the respondents, (1) resource scarcity, (2) the underlying causes of resource scarcity, (3) the role of traditional authority in managing resources, and (4) strategies used by community members in the face of resource scarcity. The results have important implications for the well-being of both social and natural systems in many transitional, rural developing societies. PMID:21909188

2015-01-01

A method for acquiring albumin-corrected fructosamine values from whole blood using a microfluidic paper-based analytical system that offers substantial improvement over previous methods is proposed. The time required to quantify both serum albumin and fructosamine is shortened to 10 min with detection limits of 0.50 g dl(-1) and 0.58 mM, respectively (S/N = 3). The proposed system also exhibited good within-run and run-to-run reproducibility. The results of the interference study revealed that the acceptable recoveries ranged from 95.1 to 106.2%. The system was compared with currently used large-scale methods (n = 15), and the results demonstrated good agreement among the techniques. The microfluidic paper-based system has the potential to continuously monitor glycemic levels in low resource settings.

2018-03-01

The necessity for considering both strength criteria and postbuckling effects in calculating the load-carrying capacity in compression of thin-wall composite structures with impact damage is substantiated. An original applied method ensuring solution of these problems with an accuracy sufficient for practical design tasks is developed. The main advantage of the method is its applicability in terms of computing resources and the set of initial data required. The results of application of the method to solution of the problem of compression of fragments of thin-wall honeycomb panel damaged by impacts of various energies are presented. After a comparison of calculation results with experimental data, a working algorithm for calculating the reduction in the load-carrying capacity of a composite object with impact damage is adopted.

Computational aerodynamics and artificial intelligence

The general principles of artificial intelligence are reviewed and speculations are made concerning how knowledge based systems can accelerate the process of acquiring new knowledge in aerodynamics, how computational fluid dynamics may use expert systems, and how expert systems may speed the design and development process. In addition, the anatomy of an idealized expert system called AERODYNAMICIST is discussed. Resource requirements for using artificial intelligence in computational fluid dynamics and aerodynamics are examined. Three main conclusions are presented. First, there are two related aspects of computational aerodynamics: reasoning and calculating. Second, a substantial portion of reasoning can be achieved with artificial intelligence. It offers the opportunity of using computers as reasoning machines to set the stage for efficient calculating. Third, expert systems are likely to be new assets of institutions involved in aeronautics for various tasks of computational aerodynamics.

Psychiatric disorders in military members require substantial medical, administrative, and financial resources, and are among the leading causes of hospitalization and early discharge. We reviewed available data to better understand the incidence of bipolar I disorder among military personnel. Defense Medical Epidemiology Database inpatient data were used. Descriptive and comparative statistics were performed. From 1997-2006 there were 3,317 first hospitalizations for bipolar I disorder with a mean of 1.2 hospitalizations per case. The rate of first occurrence among this adult population was 0.24 per 1,000 person-years. The incidence increased over time for depressed and mixed episode types among both genders. High risk groups include women, younger individuals, and whites. This population provides insight into adult onset bipolar I disorder incidence and demographic patterns not available elsewhere and offers potential opportunities to improve its understanding.

The energy crisis, which becomes more evident in Russia, stems in many respects from unjustified high consumption of energy resources. Development and exploitation of principal oil and gas deposits located in remote areas with severe climatic conditions require considerable investments increasing essentially the cost of power generation. Account should be taken also of the fact that oil and gas resources are nonrenewable. An alternative fuel for heat and power generation is coal, the reserves of which in Russia are quite substantial. For this reason the coal extraction by 2020 will amount to 450-550 million tons. The use of coal, as a solid fuel for heat power plants and heating plants, is complicated by its transportation from extraction to processing and consumption sites. Remoteness of the principal coal mining areas (Kuzbass, Kansk-Achinsk field, Vorkuta) from the main centers of its consumption in the European part of the country, Siberia and Far East makes the problem of coal transportation urgent. Of all possible transportation methods (railway, conveyor, pipeline), the most efficient is hydrotransport which provides continuous transportation at comparatively low capital and working costs, as confirmed by construction and operation of extended coal pipelines in many countries.

Challenges of Developing Design Discharge Estimates with Uncertain Data and Information

NASA Astrophysics Data System (ADS)

Senarath, S. U. S.

2016-12-01

This study focuses on design discharge estimates obtained for gauged basins through flood flow frequency analysis. Bulletin 17B (B17B) guidelines are widely used in the USA for developing these design estimates, which are required for many water resources engineering design applications. A set of outlier and historical data, and distribution parameter selection options is included in these guidelines. These options are provided in the guidelines as a means of accounting for uncertain data and information, primarily in the flow record. The individual as well as the cumulative effects of each of these preferences on design discharge estimates are evaluated in this study by using data from several gauges that are part of the United States Geological Survey's Hydro-Climatic Data Network. The results of this study show that despite the availability of rigorous and detailed guidelines for flood frequency analysis, the design discharge estimates can still vary substantially, from user to user, based on data and model parameter selection options chosen by each user. Thus, the findings of this study have strong implications for water resources engineers and other professionals who use B17B-based design discharge estimates in their work.

Effective utilisation of collaborative non-governmental organisation (NGO)-public health system linkages in pluralistic health systems of developing countries can substantially improve equity and quality of services. This study explores level and types of linkages between public health sector and NGOs in Uttar Pradesh (UP), an underprivileged state of India, using a social science model for the first time. It also identifies gaps and challenges for effective linkage. Two NGOs were selected as case studies. Data collection included semi-structured in-depth interviews with senior staff and review of records and reporting formats. Formal linkages of NGOs with the public health system related to registration, participation in district level meetings, workforce linkages and sharing information on government-supported programmes. Challenges included limited data sharing, participation in planning and limited monitoring of regulatory compliances. Linkage between public health system and NGOs in UP was moderate, marked by frequent interaction and some reciprocity in information and resource flows, but weak participation in policy and planning. The type of linkage could be described as 'complementarity', entailing information and resource sharing but not joint action. Stronger linkage is required for sustained and systematic collaboration, with joint planning, implementation and evaluation.

Intergenerational aspects of government policy under changing demographic and economic conditions.

PubMed

Boskin, M J

1987-07-01

Changing demographic and economic conditions in the US require that attention be given to some of the intergenerational equity features of government policy. In particular, social insurance programs and public debt leave public liabilities to future generations. Taken in the aggregate, the effects of rapidly rising public debt and especially social insurance programs are transferring substantial amounts of resources from younger working generations to the expanding generation of retirees. The most crucial element in evaluating the desirability of intergenerational wealth distribution in the long run is the rate of economic growth. A society's monetary, fiscal, tax, and regulatory policies can be more or less conducive to the generation of capital formation, technical change, and economic growth. Policies that influence growth and interest rates will combine with the national deficit to determine how rapidly the debt grows or shrinks. Present accounting procedures are insufficient to provide quantitative answers to the question of what is the impact of a given program on the age-specific distributions of resources. It is important to reconsider the desirability and efficiency of intergenerational redistributions of wealth in the US. It is likely that current policies are not in line with the principles of efficiency, equity, target effectiveness, and cost effectiveness.

1982-09-01

A public consensus has developed on the need for national energy policies and better planning in the utilization of energy resources in Nigeria. A look at Nigeria's energy future is timely as a period of rapid technological growth and industrial development begins. At the present time, Nigeria exports a relatively high percentage (92%) of the petroleum produced annually. In addition, about 95% of all produced natural gas is flared. Only a relatively minor fraction of the coal produced is used and the rest exported to West African countries. Water power in Nigeria is not yet fully developed. Although the depositsmore » of uranium and oil sand may be substantial, the reserves are not currently known. The proportions in which mineral fuels are used are not related to their relative abundance. Based on present production rates, domestic reserves of petroleum will last 20 years, those of natural gas 63 years, and those of coal 1503 years. Nigeria is not currently and is not likely to become self-sufficient in terms of energy requirements. During the past decade, Nigeria's population has increased by 28.4%. Of vital concern for the immediate future in Nigeria are the demands on energy consumption and mineral resources resulting from increasing population pressure.« less

Debt relief and public health spending in heavily indebted poor countries.

Gupta, Sanjeev; Clements, Benedict; Guin-Siu, Maria Teresa; Leruth, Luc

2002-01-01

The Heavily Indebted Poor Countries (HIPC) Initiative, which was launched in 1996, is the first comprehensive effort by the international community to reduce the external debt of the world's poorest countries. The Initiative will generate substantial savings relative to current and past public spending on health and education in these countries. Although there is ample scope for raising public health spending in heavily indebted poor countries, it may not be advisable to spend all the savings resulting from HIPC resources for this purpose. Any comprehensive strategy for tackling poverty should also focus on improving the efficiency of public health outlays and on reallocating funds to programmes that are most beneficial to the poor. In order to ensure that debt relief increases poverty-reducing spending and benefits the poor, all such spending, not just that financed by HIPC resources, should be tracked. This requires that countries improve all aspects of their public expenditure management. In the short run, heavily indebted poor countries can take some pragmatic tracking measures based on existing public expenditure management systems, but in the longer run they should adopt a more comprehensive approach so as to strengthen their budget formulation, execution, and reporting systems.

In response to the growing epidemic of antibiotic-resistant bacterial infections, antimicrobial stewardship programs (ASP) have been rapidly implemented in the United States (US). This study examines the prevalence of the Centers for Disease Control and Prevention’s (CDC) seven core elements of a successful ASP within a large subset of US Children’s Hospitals. In 2016, a survey was conducted of 52 pediatric hospitals assessing the presence of the seven core elements: leadership commitment, accountability, drug expertise, action, tracking, reporting, and education. Forty-nine hospitals (94%) had established ASPs and 41 hospitals (79%) included all seven core elements. Physician accountability (87%) and a dedicated ASP pharmacist or drug expert (88%) were present in the vast majority of hospitals. However, substantial variability existed in the financial support allotted to these positions. This variability did not predict program actions, tracking, reporting, and education. When compared with previous surveys, these results document a dramatic increase in the prevalence and resources of pediatric stewardship programs, although continued expansion is warranted. Further research is required to understand the feasibility of various core stewardship activities and the impact on patient outcomes in the setting of finite resources. PMID:29370071

The Miranda Pine, Horseshoe Springs, Tepusquet Peak, La Brea, Spoor Canyon, Fox Mountain and Little Pine Roadless Areas together occupy about 246 sq mi in the Los Padres National Forest, California. Mineral-resource surveys indicate demonstrated resources of barite, copper, and zinc at two localities in the La Brea Roadless Area and demonstrated resources of phosphate at a mine in the Fox Mountain Roadless Area. A building stone quarry is present on the southern border of the Horseshoe Spring Roadless Area and an area of substantiated resource potential extends into the area. The Miranda Pine, Tepusquet Peak, Spoor Canyon, and Little Pine Roadless Areas have little promise for the occurrence of mineral resources and there is little promise for the occurrence of energy resources in any of the roadless areas.

Web-based health resources at US colleges: early patterns and missed opportunities in preventive health.

Jue, J Jane S; Metlay, Joshua P

2011-11-01

Web-based health resources on college websites have the potential to reach a substantial number of college students. The objective of this study was to characterize how colleges use their websites to educate about and promote health. This study was a cross-sectional analysis of websites from a nationally representative sample of 426 US colleges. Reviewers abstracted information about Web-based health resources from college websites, namely health information, Web links to outside health resources, and interactive Web-based health programs. Nearly 60% of US colleges provided health resources on their websites, 49% provided health information, 48% provided links to outside resources, and 28% provided interactive Web-based health programs. The most common topics of Web-based health resources were mental health and general health. We found widespread presence of Web-based health resources available from various delivery modes and covering a range of health topics. Although further research in this new modality is warranted, Web-based health resources hold promise for reaching more US college students.

Simons, Frank S.; Lambeth, Robert H.

1984-01-01

A mineral-resource survey of the Madison Roadless Area in the Madison Range of southwestern Montana was made. The Madison Roadless Area has demonstrated resources of about 93,000 tons of sillimanite rock at the Placer Creek deposit and of about 83,000 tons of asbestos rock at the Karst deposit. The roadless area also has areas of substantiated phosphate resource potential; much of the phosphate is in thin deeply buried beds. An area near the south edge of the roadless area has a probable resource potential for copper and silver. The concentration of uranium-rich stream-sediment samples in the southwest part of the roadless area suggests that a further attempt to identify the source rocks might be justified.

Geothermal energy: clean power from the Earth's heat

USGS Publications Warehouse

Duffield, Wendell A.; Sass, John H.

2003-01-01

Societies in the 21st century require enormous amounts of energy to drive the machines of commerce and to sustain the lifestyles that many people have come to expect. Today, most of this energy is derived from oil, natural gas, and coal, supplemented by nuclear power. Local exceptions exist, but oil is by far the most common source of energy worldwide. Oil resources, however, are nonrenewable and concentrated in only a few places around the globe, creating uncertainty in long-term supply for many nations. At the time of the Middle East oil embargo of the 1970s, about a third of the United States oil supply was imported, mostly from that region. An interruption in the flow of this import disrupted nearly every citizen’s daily life, as well as the Nation’s economy. In response, the Federal Government launched substantial programs to accelerate development of means to increasingly harness “alternative energies”—primarily biomass, geothermal, solar, and wind. The new emphasis on simultaneously pursuing development of several sources of energy recognized the timeless wisdom found in the proverb of “not putting all eggs in one basket.” This book helps explain the role that geothermal resources can play in helping promote such diversity and in satisfying our Nation’s vast energy needs as we enter a new millennium. For centuries, people have enjoyed the benefits of geothermal energy available at hot springs, but it is only through technological advances made during the 20th century that we can tap this energy source in the subsurface and use it in a variety of ways, including the generation of electricity. Geothermal resources are simply exploitable concentrations of the Earth’s natural heat (thermal energy). The Earth is a bountiful source of thermal energy, continuously producing heat at depth, primarily by the decay of naturally occurring radioactive isotopes—principally of uranium, thorium, and potassium—that occur in small amounts in all rocks. This heat then rises to and through the Earth’s surface, where it escapes into the atmosphere. The amount of heat that flows annually from the Earth into the atmosphere is enormous—equivalent to ten times the annual energy consumption of the United States and more than that needed to power all nations of the world, if it could be fully harnessed. Even if only 1 percent of the thermal energy contained within the uppermost 10 kilometers of our planet could be tapped, this amount would be 500 times that contained in all oil and gas resources of the world. How might we benefit from this vast amount of thermal energy beneath our feet? Where, by what means, and how much of the Earth’s natural heat can be usefully harnessed? These are especially important questions to contemplate, because global population is expected to soon exceed seven billion and many scientists believe that the world’s fossilfuel resources may be substantially depleted within this century. Faced with such prospects, both the public and private sectors are working toward more fully utilizing the Earth’s abundant thermal energy and other alternative energy resources. A skeptic might question the wisdom of devoting much national effort to geothermal energy development, especially because many experts think that geothermal heat can contribute at most about 10 percent to the Nation’s energy supply using current technologies. However, ongoing advances in exploration and heat-extraction technologies are improving our ability to use the resource and may substantially increase the geothermal contribution to the Nation’s energy supply. In an attempt to help national planners and average citizens alike understand the nature and energy potential of geothermal resources, this book (1) describes the distribution and nature of geothermal energy, (2) reviews the common types of geothermal systems that provide useful energy with current technology, (3) considers potential geothermal resources that might someday be tapped with developing technologies, and (4) summarizes the role of earth-science information in assessing and harnessing geothermal resources wherever they occur worldwide. The predecessor to this book (Tapping the Earth’s Natural Heat, U.S. Geological Survey Circular 1125, published in 1994) summarized the situation in the early 1990s. In an effort to support national energy planners, this new circular incorporates more recent advances in geothermal science and technology.

Genome Resource Banking of Biomedically Important Laboratory Animals

PubMed Central

Agca, Yuksel

2014-01-01

Genome resource banking (GRB) is the systematic collection, storage, and re-distribution of biomaterials in an organized, logistical, and secure manner. Genome cyrobanks usually contain biomaterials and associated genomic information essential for progression of biomedicine, human health, and research. In that regard, appropriate genome cryobanks could provide essential biomaterials for both current and future research projects in the form of various cell types and tissues, including sperm, oocytes, embryos, embryonic or adult stem cells, induced pluripotent stem cells, and gonadal tissues. In addition to cryobanked germplasm, cryobanking of DNA, serum, blood products, and tissues from scientifically, economically and ecologically important species has become a common practice. For revitalization of the whole organism, cryopreserved germplasm in conjunction with assisted reproductive technologies (ART), offer a powerful approach for research model management, as well as assisting in animal production for agriculture, conservation, and human reproductive medicine. Recently, many developed and developing countries have allocated substantial resources to establish genome resources banks which are responsible for safeguarding scientifically, economically and ecologically important wild type, mutant and transgenic plants, fish, and local livestock breeds, as well as wildlife species. This review is dedicated to the memory of Dr. John K. Critser, who had made profound contributions to the science of cryobiology and establishment of genome research and resources centers for mice, rats and swine. Emphasis will be given to application of GRBs to species with substantial contributions to the advancement of biomedicine and human health. PMID:22981880

An overview of the Office of Aeronautics, Exploration, and Technology (OAET) Space Station Freedom Technology Payload Development Program is provided, and the OAET Station resource requirements are reviewed. The requirements are contrasted with current proposed resource allocations. A discussion of the issues and conclusions are provided. It is concluded that an overall 20 percent resource allocation is appropriate to support OAET's technology development program, that some resources are inadequate even at the 20 percent level, and that bartering resources among U.S. users and international partners and increasing the level of automation may be viable solutions to the resource constraint problem.

Role of Concentrating Solar Power in Integrating Solar and Wind Energy: Preprint

DOE Office of Scientific and Technical Information (OSTI.GOV)

Denholm, P.; Mehos, M.

2015-06-03

As wind and solar photovoltaics (PV) increase in penetration it is increasingly important to examine enabling technologies that can help integrate these resources at large scale. Concentrating solar power (CSP) when deployed with thermal energy storage (TES) can provide multiple services that can help integrate variable generation (VG) resources such as wind and PV. CSP with TES can provide firm, highly flexible capacity, reducing minimum generation constraints which limit penetration and results in curtailment. By acting as an enabling technology, CSP can complement PV and wind, substantially increasing their penetration in locations with adequate solar resource.

A distributed geo-routing algorithm for wireless sensor networks.

PubMed

Joshi, Gyanendra Prasad; Kim, Sung Won

2009-01-01

Geographic wireless sensor networks use position information for greedy routing. Greedy routing works well in dense networks, whereas in sparse networks it may fail and require a recovery algorithm. Recovery algorithms help the packet to get out of the communication void. However, these algorithms are generally costly for resource constrained position-based wireless sensor networks (WSNs). In this paper, we propose a void avoidance algorithm (VAA), a novel idea based on upgrading virtual distance. VAA allows wireless sensor nodes to remove all stuck nodes by transforming the routing graph and forwarding packets using only greedy routing. In VAA, the stuck node upgrades distance unless it finds a next hop node that is closer to the destination than it is. VAA guarantees packet delivery if there is a topologically valid path. Further, it is completely distributed, immediately responds to node failure or topology changes and does not require planarization of the network. NS-2 is used to evaluate the performance and correctness of VAA and we compare its performance to other protocols. Simulations show our proposed algorithm consumes less energy, has an efficient path and substantially less control overheads.

NASA Information Technology Implementation Plan

2000-01-01

NASA's Information Technology (IT) resources and IT support continue to be a growing and integral part of all NASA missions. Furthermore, the growing IT support requirements are becoming more complex and diverse. The following are a few examples of the growing complexity and diversity of NASA's IT environment. NASA is conducting basic IT research in the Intelligent Synthesis Environment (ISE) and Intelligent Systems (IS) Initiatives. IT security, infrastructure protection, and privacy of data are requiring more and more management attention and an increasing share of the NASA IT budget. Outsourcing of IT support is becoming a key element of NASA's IT strategy as exemplified by Outsourcing Desktop Initiative for NASA (ODIN) and the outsourcing of NASA Integrated Services Network (NISN) support. Finally, technology refresh is helping to provide improved support at lower cost. Recently the NASA Automated Data Processing (ADP) Consolidation Center (NACC) upgraded its bipolar technology computer systems with Complementary Metal Oxide Semiconductor (CMOS) technology systems. This NACC upgrade substantially reduced the hardware maintenance and software licensing costs, significantly increased system speed and capacity, and reduced customer processing costs by 11 percent.

Objectives The aim of this study was to estimate the initial development costs for an innovative talk show format tailored intervention delivered via the interactive web, for increasing cancer screening in women 50 to 75 who were non-adherent to screening guidelines for colorectal cancer and/or breast cancer. Methods The cost of the intervention development was estimated from a societal perspective. Micro costing methods plus vendor contract costs were used to estimate cost. Staff logs were used to track personnel time. Non-personnel costs include all additional resources used to produce the intervention. Results Development cost of the interactive web based intervention was $.39 million, of which 77% was direct cost. About 98% of the cost was incurred in personnel time cost, contract cost and overhead cost. Conclusions The new web-based disease prevention medium required substantial investment in health promotion and media specialist time. The development cost was primarily driven by the high level of human capital required. The cost of intervention development is important information for assessing and planning future public and private investments in web-based health promotion interventions. PMID:25749548

Long-term adequacy of metal resources

USGS Publications Warehouse

Singer, D.A.

1977-01-01

Although the earth's crust contains vast quantities of metals, extraction technologies and associated costs are inextricably bound to three fundamental geological factors - the amount of metal available in the earth's crust in each range of grades, the mineralogical form and chemical state of the metal, and the spatial distribution of the metal. The energy required to recover a given amount of metal increases substantially as grade declines. Most metal is produced from sulphide or oxide minerals, whereas most metal in the crust may be locked in the structures of the more refractory silicates. Recovery from silicate minerals could require orders of magnitude more energy than that used at present as also could exploitation of small, widely scattered or thin, deeply buried deposits. Although specific information on the fundamental factors is not available, each factor must in turn tend to further restrict exploitation. Independence of average grade and tonnage for many deposit types further reduces the availability of rock as a source of metal. In the long term, effects of these factors will be large increases in price for many metals. ?? 1977.

Understanding and predicting ecological dynamics: Are major surprises inevitable

Ecological surprises, substantial and unanticipated changes in the abundance of one or more species that result from previously unsuspected processes, are a common outcome of both experiments and observations in community and population ecology. Here, we give examples of such surprises along with the results of a survey of well-established field ecologists, most of whom have encountered one or more surprises over the course of their careers. Truly surprising results are common enough to require their consideration in any reasonable effort to characterize nature and manage natural resources. We classify surprises as dynamic-, pattern-, or intervention-based, and we speculate on the common processes that cause ecological systems to so often surprise us. A long-standing and still growing concern in the ecological literature is how best to make predictions of future population and community dynamics. Although most work on this subject involves statistical aspects of data analysis and modeling, the frequency and nature of ecological surprises imply that uncertainty cannot be easily tamed through improved analytical procedures, and that prudent management of both exploited and conserved communities will require precautionary and adaptive management approaches.

Going glass to digital: virtual microscopy as a simulation-based revolution in pathology and laboratory science.

2012-10-01

The recent technological advance of digital high resolution imaging has allowed the field of pathology and medical laboratory science to undergo a dramatic transformation with the incorporation of virtual microscopy as a simulation-based educational and diagnostic tool. This transformation has correlated with an overall increase in the use of simulation in medicine in an effort to address dwindling clinical resource availability and patient safety issues currently facing the modern healthcare system. Virtual microscopy represents one such simulation-based technology that has the potential to enhance student learning and readiness to practice while revolutionising the ability to clinically diagnose pathology collaboratively across the world. While understanding that a substantial amount of literature already exists on virtual microscopy, much more research is still required to elucidate the full capabilities of this technology. This review explores the use of virtual microscopy in medical education and disease diagnosis with a unique focus on key requirements needed to take this technology to the next level in its use in medical education and clinical practice.

Public health research requires sound design and thoughtful consideration of potential biases that may influence the validity of results. It also requires careful implementation of protocols and procedures that are likely to translate from the research environment to actual clinical practice. This article is the product of a breakout session from the 2009 Academic Emergency Medicine consensus conference entitled “Public Health in the ED: Screening, Surveillance, and Intervention” and serves to describe in detail aspects of performing emergency department (ED)-based public health research, while serving as a resource for current and future researchers. In doing so, the authors describe methodologic features of study design, participant selection and retention, and measurements and analyses pertinent to public health research. In addition, a number of recommendations related to research methods and future investigations related to public health work in the ED are provided. Public health investigators are poised to make substantial contributions to this important area of research, but this will only be accomplished by employing sound research methodology in the context of rigorous program evaluation.

[The demographic development in Germany : challenge and chances for urology].

PubMed

Schneider, A W; Fichtner, J

2014-08-01

Urology is affected by the demographic development in Germany more than any other medical discipline. Despite a relatively stable total population, by the year 2040 there will be an absolute and relevant increase in urological diseases caused only by the demographic development in the population. This is particularly true for the increase in oncological treatment just in the field of the discipline of urology. Even now the current numbers for tumor development in Germany (RKI 2014) in the urological oncology segment of all tumor diseases show an increasing trend with more than 23 %. This significant increase in performance is in contrast to the age development of the specialists in this discipline. In total but especially due to the significantly over-aged specialist medical profession in urology, this leads to a substantial bottleneck of specialists in the discipline of urology. This deficiency of personnel resources in urology is aggravated by the requirements of Generation Y for a well-adjusted work-life balance and the associated feminization of the medical profession. This requires intelligent strategies for.

Phase-Reference-Free Experiment of Measurement-Device-Independent Quantum Key Distribution

Measurement-device-independent quantum key distribution (MDI QKD) is a substantial step toward practical information-theoretic security for key sharing between remote legitimate users (Alice and Bob). As with other standard device-dependent quantum key distribution protocols, such as BB84, MDI QKD assumes that the reference frames have been shared between Alice and Bob. In practice, a nontrivial alignment procedure is often necessary, which requires system resources and may significantly reduce the secure key generation rate. Here, we propose a phase-coding reference-frame-independent MDI QKD scheme that requires no phase alignment between the interferometers of two distant legitimate parties. As a demonstration, a proof-of-principle experiment using Faraday-Michelson interferometers is presented. The experimental system worked at 1 MHz, and an average secure key rate of 8.309 bps was obtained at a fiber length of 20 km between Alice and Bob. The system can maintain a positive key generation rate without phase compensation under normal conditions. The results exhibit the feasibility of our system for use in mature MDI QKD devices and its value for network scenarios.

Geographic information system development in the CARETS project

USGS Publications Warehouse

Mitchell, William B.; Fegeas, Robin G.; Fitzpatrick, Katherine A.; Hallam, Cheryl A.

1977-01-01

Experience in the development of a geographic information system to support the CARETS project has confirmed the considerable advantages that may accrue by paralleling the system development with a rational and balanced system production effort which permits the integration of the education and training of users with interim deliverable products to them. Those advantages include support for a long-term staff plan that recognizes substantial staff changes through system development and implementation, a fiscal plan that provides continuity in resources necessary for total system development, and a feedback system which allows the user to communicate his experiences in using the system. Thus far balance between system development and system production has not been achieved because of continuing large-scale spatial data processing requirements coupled with strong and insistent demands from users for immediately deliverable products from the system. That imbalance has refocussed staffing and fiscal plans from long-term system development to short- and near-term production requirements, continuously extends total system development time, and increases the possibility that later system development may reduce the usefulness of current interim products.

Simulating compressible-incompressible two-phase flows

NASA Astrophysics Data System (ADS)

Denner, Fabian; van Wachem, Berend

2017-11-01

Simulating compressible gas-liquid flows, e.g. air-water flows, presents considerable numerical issues and requires substantial computational resources, particularly because of the stiff equation of state for the liquid and the different Mach number regimes. Treating the liquid phase (low Mach number) as incompressible, yet concurrently considering the gas phase (high Mach number) as compressible, can improve the computational performance of such simulations significantly without sacrificing important physical mechanisms. A pressure-based algorithm for the simulation of two-phase flows is presented, in which a compressible and an incompressible fluid are separated by a sharp interface. The algorithm is based on a coupled finite-volume framework, discretised in conservative form, with a compressive VOF method to represent the interface. The bulk phases are coupled via a novel acoustically-conservative interface discretisation method that retains the acoustic properties of the compressible phase and does not require a Riemann solver. Representative test cases are presented to scrutinize the proposed algorithm, including the reflection of acoustic waves at the compressible-incompressible interface, shock-drop interaction and gas-liquid flows with surface tension.

The capability to locate, mine, and process the natural resources of the Moon will be an essential requirement for lunar base development and operation. The list of materials that will be necessary is extensive and ranges from oxygen and hydrogen for fuel and life support to process tailings for emplacement over habitats. Despite the resources need, little is known about methodologies that might be suitable for utilizing lunar resources. This paper examines some of the requirements and constraints for resource recovery and identifies key areas of research needed to locate, mine, and process extraterrestrial natural resources.

Mobile phone imaging and cloud-based analysis for standardized malaria detection and reporting.

Scherr, Thomas F; Gupta, Sparsh; Wright, David W; Haselton, Frederick R

2016-06-27

Rapid diagnostic tests (RDTs) have been widely deployed in low-resource settings. These tests are typically read by visual inspection, and accurate record keeping and data aggregation remains a substantial challenge. A successful malaria elimination campaign will require new strategies that maximize the sensitivity of RDTs, reduce user error, and integrate results reporting tools. In this report, an unmodified mobile phone was used to photograph RDTs, which were subsequently uploaded into a globally accessible database, REDCap, and then analyzed three ways: with an automated image processing program, visual inspection, and a commercial lateral flow reader. The mobile phone image processing detected 20.6 malaria parasites/microliter of blood, compared to the commercial lateral flow reader which detected 64.4 parasites/microliter. Experienced observers visually identified positive malaria cases at 12.5 parasites/microliter, but encountered reporting errors and false negatives. Visual interpretation by inexperienced users resulted in only an 80.2% true negative rate, with substantial disagreement in the lower parasitemia range. We have demonstrated that combining a globally accessible database, such as REDCap, with mobile phone based imaging of RDTs provides objective, secure, automated, data collection and result reporting. This simple combination of existing technologies would appear to be an attractive tool for malaria elimination campaigns.

Cage culture plays an important role in achieving higher output and generating more export earnings in Malaysia. However, the cost of fingerlings, feed and labour have increased substantially for cage culture in the coastal areas in Peninsular Malaysia. This paper uses farm level data gathered from Manjung, Perak and Kota Tinggi, Johor to investigate the technical efficiency of brackish water fish cage culture using the stochastic frontier approach. The technical efficiency was estimated and specifically the factors affecting technical inefficiencies of fish cage culture system in Malaysia was investigated. On average, 37 percent of the sampled fish cage farms are technically efficient. The results suggest very high degrees of technical inefficiency exist among the cage culturists. This implies that great potential exists to increase fish production through improved efficiency in cage culture management in Peninsular Malaysia. The results indicate that farmers obtained grouper fingerlings from other neighboring countries due to scarcity of fingerlings from wild sources. The cost of feeding for grouper (Epinephelus fuscoguttatus) requires relatively higher costs compared to seabass (Lates calcarifer) production in cage farms in the study areas. Initiatives to undertake extension programmes at the farm level are needed to help cage culturists in utilizing their resources more efficiently in order to substantially enhance their fish production.

A comparison between the dynamics of horizontal and vertical axis offshore floating wind turbines.

PubMed

Borg, M; Collu, M

2015-02-28

The need to further exploit offshore wind resources in deeper waters has led to a re-emerging interest in vertical axis wind turbines (VAWTs) for floating foundation applications. However, there has been little effort to systematically compare VAWTs to the more conventional horizontal axis wind turbine (HAWT). This article initiates this comparison based on prime principles, focusing on the turbine aerodynamic forces and their impact on the floating wind turbine static and dynamic responses. VAWTs generate substantially different aerodynamic forces on the support structure, in particular, a potentially lower inclining moment and a substantially higher torque than HAWTs. Considering the static stability requirements, the advantages of a lower inclining moment, a lower wind turbine mass and a lower centre of gravity are illustrated, all of which are exploitable to have a less costly support structure. Floating VAWTs experience increased motion in the frequency range surrounding the turbine [number of blades]×[rotational speed] frequency. For very large VAWTs with slower rotational speeds, this frequency range may significantly overlap with the range of wave excitation forces. Quantitative considerations are undertaken comparing the reference NREL 5 MW HAWT with the NOVA 5 MW VAWT. © 2015 The Author(s) Published by the Royal Society. All rights reserved.

Rapid diagnostic tests (RDTs) have been widely deployed in low-resource settings. These tests are typically read by visual inspection, and accurate record keeping and data aggregation remains a substantial challenge. A successful malaria elimination campaign will require new strategies that maximize the sensitivity of RDTs, reduce user error, and integrate results reporting tools. In this report, an unmodified mobile phone was used to photograph RDTs, which were subsequently uploaded into a globally accessible database, REDCap, and then analyzed three ways: with an automated image processing program, visual inspection, and a commercial lateral flow reader. The mobile phone image processing detected 20.6 malaria parasites/microliter of blood, compared to the commercial lateral flow reader which detected 64.4 parasites/microliter. Experienced observers visually identified positive malaria cases at 12.5 parasites/microliter, but encountered reporting errors and false negatives.

Evaluation and removal of home hazards is an invaluable method for preventing in-home falls and preserving independent living. Current processes for conducting home hazard assessments are impractical from a whole population standpoint given the substantial resources required for implementation. Digital photography offers an opportunity to remotely evaluate an environment for falling hazards. However, reliability of this method has only been tested under the direction of skilled therapists. Ten community dwelling adults over the age of 65 were recruited from local primary care practices between July, 2009 and February, 2010. In-home (IH) assessments were completed immediately after a photographer, blinded to the assessment form, took digital photographs (DP) of the participant home. A different non-therapist assessor then reviewed the photographs and completed a second assessment of the home. Kappa statistic was used to analyze the reliability between the two independent assessments. Home assessments completed by a non-therapist using digital photographs had a substantial agreement (Kappa = 0.61, p < 0.001) with in-home assessments completed by another non-therapist. Additionally, the DP assessments agreed with the IH assessments on the presence or absence of items 96.8% of the time. This study showed that non-therapists can reliably conduct home hazard evaluations using digital photographs.

A budget impact analysis of parenteral iron treatments for iron deficiency anemia in the UK: reduced resource utilization with iron isomaltoside 1000.

PubMed

Pollock, Richard F; Muduma, Gorden

2017-01-01

The reported prevalence of iron deficiency anemia (IDA) varies widely but estimates suggest that 3% of men and 8% of women have IDA in the UK. Parenteral iron is indicated for patients intolerant or unresponsive to oral iron or requiring rapid iron replenishment. This study evaluated differences in the cost of treating these patients with iron isomaltoside (Monofer ® , IIM) relative to other intravenous iron formulations. A budget impact model was developed to evaluate the cost of using IIM relative to ferric carboxymaltose (Ferinject ® , FCM), low molecular weight iron dextran (Cosmofer ® , LMWID), and iron sucrose (Venofer ® , IS) in patients with IDA. To establish iron need, iron deficits were modeled using a simplified dosing table. The base case analysis was conducted over 1 year in patients with IDA with mean bodyweight of 82.4 kg (SD 22.5 kg) and hemoglobin levels of 9.99 g/dL (SD 1.03 g/dL) based on an analysis of patient characteristics in IDA trials. Costs were modeled using UK health care resource groups. Using IIM required 1.3 infusions to correct the mean iron deficit, compared with 1.3, 1.8, and 7.7 with LMWID, FCM, and IS, respectively. Patients using IIM required multiple infusions in 35% of cases, compared with 35%, 77%, and 100% of patients with LMWID, FCM, and IS, respectively. Total costs were estimated to be GBP 451 per patient with IIM or LMWID, relative to GBP 594 with FCM (a GBP 143 or 24% saving with IIM) or GBP 2,600 with IS (a GBP 2,149 or 83% saving with IIM). Using IIM or LMWID in place of FCM or IS resulted in a marked reduction in the number of infusions required to correct iron deficits in patients with IDA. The reduction in infusions was accompanied by substantial reductions in cost relative to FCM and IS over 1 year.

Hydrologic Investigations Concerning Lead Mining Issues in Southeastern Missouri

USGS Publications Warehouse

Kleeschulte, Michael J.

2008-01-01

Good stewardship of our Nation's natural resources demands that the extraction of exploitable, minable ore deposits be conducted in harmony with the protection of the environment, a dilemma faced by many land and water management agencies in the Nation's mining areas. As ore is mined, milled, and sent to the smelter, it leaves footprints where it has been in the form of residual trace metals. Often these footprints become remnants that can be detrimental to other natural resources. This emphasizes the importance of understanding the earth's complex physical and biological processes and their interactions at increasingly smaller scales because subtle changes in one component can substantially affect others. Understanding these changes and resulting effects requires an integrated, multidisciplinary scientific approach. As ore reserves are depleted in one area, additional exploitable deposits are required to replace them, and at times these new deposits are discovered in previously unmined areas. Informed decisions concerning resource management in these new, proposed mining areas require an understanding of the potential consequences of the planned mining actions. This understanding is usually based on knowledge that has been accumulated from studying previously mined areas with similar geohydrologic and biologic conditions. If the two areas experience similar mining practices, the information should be transferable. Lead and zinc mining along the Viburnum Trend Subdistrict of southeastern Missouri has occurred for more than 40 years. Additional potentially exploitable deposits have been discovered 30 miles to the south, within the Mark Twain National Forest. It is anticipated that the observation of current (2008) geohydrologic conditions in the Viburnum Trend can provide insight to land managers that will help reasonably anticipate the potential mining effects should additional mining occur in the exploration area. The purpose of this report is to present a compilation of previously unpublished information that was collected as part of a larger multidisciplinary study of lead mining issues in southeastern Missouri. The report resulted from the application of a multidisciplinary approach to investigate current hydrologic and biologic conditions in streams of the Viburnum Trend and the exploration area in the Mark Twain National Forest.

Rural rehabilitation practice: perspectives of occupational therapists and physical therapists in British Columbia, Canada.

2014-01-01

Providing rehabilitation services to address the health needs of rural residents requires overcoming the challenges of geography, limited referral options and a shortage of occupational therapists (OTs) and physical therapists (PTs). However, little is known about how rehabilitation professionals in rural areas enact their practice to meet and overcome these challenges. To address this gap and contribute to enhancing health for rural residents, this study was designed to explore rural rehabilitation practice from the perspectives of OTs and PTs in rural British Columbia (BC). A purposive sample of OTs and PTs in rural communities (population <15 000) in northern BC was recruited for this qualitative study. Potential participants received an invitation mailed to workplaces and were selected to ensure a variety of work experiences, roles and practice settings. In semi-structured interviews, participants were asked to describe the skills and knowledge they perceived as unique to rural practice and strategies they used to overcome challenges. Guided by interpretive description, transcripts were analysed inductively using broad-level coding, and findings were collapsed into interpretive categories. Interpretations and implications for education, practice and policy were reviewed with participants to ensure relevance to rural practice. From interviews with 6 OTs and 13 PTs, serving a total of 15 rural communities, rehabilitation practice and participants' definition of health were understood to be substantially shaped by rurality or the contextual features of geography, determinants of health and access to services. Participants considered general practice 'a specialty' requiring advanced skills in assessment. They described 'stretching their role' and 'participating in, and partnerships with, community' as ways to overcome resource shortages. Reflective practice, networking and collaboration were deemed essential to maintaining competence. Rural clinical placements, mentoring and improving access to continuing professional development were regarded as central to the recruitment and retention required to sustain optimal levels of service to residents. The research findings illustrate the unique influence that the rural context has on the practice of OTs and PTs in BC. They underscore the importance of facilitating learning about rural health within professional training programs and of providing accessible professional development resources to address health human resource shortages and meet the rehabilitation needs of rural residents.

Between a rock and a hard place: Learning to teach science-for-all in an urban district

NASA Astrophysics Data System (ADS)

Galosy, Jodie A.

2005-07-01

Science-for-all, a contemporary science education reform initiative, envisions science classrooms where all students have opportunities to deepen their understanding of scientific concepts and practices. However, national science achievement tests indicate the reality of science-for-all is still very much a work-in-progress. Science-for-all demands much of teachers, especially those working with student populations typically underserved by science education---students of color, students with limited English proficiency, and those from families with limited economic means. A large proportion of those students attend urban districts where they are likely to encounter novice science teachers. This qualitative study investigated learning to teach science-for-all in an urban school district. Seven early career middle and high school science teachers participated in the study. Data collection took place over a period of fourteen months, through interviews and observations with teacher participants, their schools, and in their professional development activities (including new teacher support induction programs). The study examines how new teachers' use of their personal, social, and conventional resources influenced their beliefs and practices relative to science-for-all. Three reform ideals serve as the study's focal points: content goals that emphasize understanding scientific concepts and practices, hands-on activities that support students' intellectual engagement, and literacy strategies that provide access for all students to scientific content. Few novices developed beliefs and practices that supported science-for-all. Those who did brought several key personal resources to their teaching. While these personal resources were important for teacher development, they were not sufficient; novices needed additional resources. Some teachers had access to reform-based conventional resources others did not have. However, personal and social resources shaped how novices used those resources and, in turn, their beliefs about students and teaching practices. Context-specific assistance was a particularly important social resource that was in short supply for most novices. The study provides evidence that progress towards science-for-all will require substantial attention to, and investment in, teacher learning across all dimensions of the professional continuum---pre-service, induction, and in-service. The study also provides insights in two critical areas: strengthening the resources available to early career urban science teachers and shaping resource use towards the goals envisioned in science-for all.

This study examined knowledge, access, utilization, and barriers to use of resources among Black women exposed to multiple types of intimate partner violence in Baltimore, Maryland and the U.S. Virgin Islands (USVI). We analyzed quantitative survey data collected by 163 women recruited from primary care, prenatal or family planning clinics in Baltimore and the USVI. In addition we analyzed qualitative data from in-depth interviews with 11 women. Quantitative data were analyzed using descriptive statistics and qualitative data were analyzed using thematic analysis. A substantial proportion of Black women with multiple types of violence experiences lacked knowledge of, did not have access to, and did not use resources. Barriers to resource use were identified at the individual, relationship, and community levels. There is need for programs to develop awareness, promote access and utilization of resources, and eliminate barriers to resource use among abused Black women.

Summary There is considerable concern over declines in insect pollinator communities and potential impacts on the pollination of crops and wildflowers1–4. Among the multiple pressures facing pollinators2–4, decreasing floral resources due to habitat loss and degradation has been suggested as a key contributing factor2–8. However, a lack of quantitative data has hampered testing for historical changes in floral resources. Here we show that overall floral rewards can be estimated at a national scale by combining vegetation surveys and direct nectar measurements. We find evidence for substantial losses in nectar resources in England and Wales between the 1930s and 1970s; however, total nectar provision in Great Britain as a whole had stabilised by 1978, and increased from 1998 to 2007. These findings concur with trends in pollinator diversity, which declined in the mid-20th century9 but stabilised more recently10. The diversity of nectar sources declined from 1978 to 1990 but stabilised thereafter at low levels, with four plant species accounting for over 50% of national nectar provision in 2007. Calcareous grassland, broadleaved woodland and neutral grassland are the habitats that produce the greatest amount of nectar per unit area from the most diverse sources, whereas arable land is the poorest in both respects. While agri-environment schemes add resources to arable landscapes, their national contribution is low. Due to their large area, improved grasslands could add substantially to national nectar provision if they were managed to increase floral resource provision. This national-scale assessment of floral resource provision brings new insights into the links between plant and pollinator declines, and offers considerable opportunities for conservation.

Fostering development of nursing practices to support integrated care when implementing integrated care pathways: what levers to use?

PubMed

Longpré, Caroline; Dubois, Carl-Ardy

2017-11-29

Care integration has been the focus of recent health system reforms. Given their functions at all levels of the care continuum, nurses have a substantial and primordial role to play in such integration processes. The aim of this study was to identify levers and strategies that organizations can use to support the development of a nursing practice aligned with the requirements of care integration in a health and social services centre (HSSC) in Quebec. The research design was a cross-sectional descriptive qualitative study based on a single case study with nested levels of analysis. The case was a public, multi-disciplinary HSSC in a semi-urban region of Quebec. Semi-structured interviews with 37 persons (nurses, professionals, managers, administrators) allowed for data saturation and ensured theoretical representation by covering four care pathways constituting different care integration contexts. Analysis involved four steps: preparing a predetermined list of codes based on the reference framework developed by Minkman (2011); coding transcript content; developing general and summary matrices to group observations for each care pathway; and creating a general model showing the overall results for the four pathways. The organization's capacity for response with regard to developing an integrated system of services resulted in two types of complementary interventions. The first involved investing in key resources and renewing organizational structures; the second involved deploying a series of organizational and clinical-administrative processes. In resource terms, integration efforts resulted in setting up new strategic services, re-arranging physical infrastructures, and deploying new technological resources. Organizational and clinical-administrative processes to promote integration involved renewing governance, improving the flow of care pathways, fostering continuous quality improvement, developing new roles, promoting clinician collaboration, and strengthening care providers' capacities. However, progress in these areas was offset by persistent constraints. The results highlight key levers organizations can use to foster the implementation and institutionalization of integrative nursing practices. They show that progress in this area requires a combination of strategies using multiple complementary levers. They also suggest that such progress calls for rethinking not only the deployment of certain organizational resources and structures, but also a series of organizational and clinical processes.

Plant resources and colony growth in an invasive ant: the importance of honeydew-producing Hemiptera in carbohydrate transfer across trophic levels.

PubMed

Helms, Ken R; Vinson, S Bradleigh

2008-04-01

Studies have suggested that plant-based nutritional resources are important in promoting high densities of omnivorous and invasive ants, but there have been no direct tests of the effects of these resources on colony productivity. We conducted an experiment designed to determine the relative importance of plants and honeydew-producing insects feeding on plants to the growth of colonies of the invasive ant Solenopsis invicta (Buren). We found that colonies of S. invicta grew substantially when they only had access to unlimited insect prey; however, colonies that also had access to plants colonized by honeydew-producing Hemiptera grew significantly and substantially ( approximately 50%) larger. Our experiment also showed that S. invicta was unable to acquire significant nutritional resources directly from the Hemiptera host plant but acquired them indirectly from honeydew. Honeydew alone is unlikely to be sufficient for colony growth, however, and both carbohydrates abundant in plants and proteins abundant in animals are likely to be necessary for optimal growth. Our experiment provides important insight into the effects of a common tritrophic interaction among an invasive mealybug, Antonina graminis (Maskell), an invasive host grass, Cynodon dactylon L. Pers., and S. invicta in the southeastern United States, suggesting that interactions among these species can be important in promoting extremely high population densities of S. invicta.

Some mechanistic requirements for major transitions.

PubMed

Schuster, Peter

2016-08-19

Major transitions in nature and human society are accompanied by a substantial change towards higher complexity in the core of the evolving system. New features are established, novel hierarchies emerge, new regulatory mechanisms are required and so on. An obvious way to achieve higher complexity is integration of autonomous elements into new organized systems whereby the previously independent units give up their autonomy at least in part. In this contribution, we reconsider the more than 40 years old hypercycle model and analyse it by the tools of stochastic chemical kinetics. An open system is implemented in the form of a flow reactor. The formation of new dynamically organized units through integration of competitors is identified with transcritical bifurcations. In the stochastic model, the fully organized state is quasi-stationary whereas the unorganized state corresponds to a population with natural selection. The stability of the organized state depends strongly on the number of individual subspecies, n, that have to be integrated: two and three classes of individuals, [Formula: see text] and [Formula: see text], readily form quasi-stationary states. The four-membered deterministic dynamical system, [Formula: see text], is stable but in the stochastic approach self-enhancing fluctuations drive it into extinction. In systems with five and more classes of individuals, [Formula: see text], the state of cooperation is unstable and the solutions of the deterministic ODEs exhibit large amplitude oscillations. In the stochastic system self-enhancing fluctuations lead to extinction as observed with [Formula: see text] Interestingly, cooperative systems in nature are commonly two-membered as shown by numerous examples of binary symbiosis. A few cases of symbiosis of three partners, called three-way symbiosis, have been found and were analysed within the past decade. Four-way symbiosis is rather rare but was reported to occur in fungus-growing ants. The model reported here can be used to illustrate the interplay between competition and cooperation whereby we obtain a hint on the role that resources play in major transitions. Abundance of resources seems to be an indispensable prerequisite of radical innovation that apparently needs substantial investments. Economists often claim that scarcity is driving innovation. Our model sheds some light on this apparent contradiction. In a nutshell, the answer is: scarcity drives optimization and increase in efficiency but abundance is required for radical novelty and the development of new features.This article is part of the themed issue 'The major synthetic evolutionary transitions'. © 2016 The Author(s).

Education and Professional Outreach as an Integrated Component of Science and Graduate Education

NASA Astrophysics Data System (ADS)

Staudigel, H.; Koppers, A. A.

2007-12-01

Education and Professional Outreach (EPO) is increasingly becoming a substantive and much needed activity for scientists. Significant efforts are expended to satisfy funding agency requirements, but such requirements may also develop into a mutually beneficial collaboration between scientists and K-16 educators with a minimal impact on science productivity. We focus here on two particularly high impact EPO opportunities, hosting of high school interns and the inclusion of an educational component to a graduate student's&pthesis work. We emphasize the importance of hands-on collaboration with teachers and teacher-educators, and the substantive benefits of highly leveraged customized internet-distribution. We will present two examples for how we integrated this K-12 EPO into our university-based science and education efforts, what types of products emerged from these activities, and how such products may be widely produced by any scientist and disseminated to the educational community. High school seniors offer a unique resource to university EPO because some of them can substantively contribute to the science, and they can be very effective peer-mentors for high and middle schools. Extended internships may be built easily into the schedule of many senior high school student programs, and we were able to involve such interns into a three-week seagoing expedition. The seniors were responsible for our EPO by maintaining a cruise website and video conferencing with their high school. They added substantially to the science outcome, through programming and participating in a range of shipboard science chores. Graduate theses may be augmented with an educational component that places the main theme of the thesis into an educational setting. We designed and supervised such a Master's graduate thesis with an educational component on the geochronology of hot spot volcanoes, including a high school lesson plan, enactment in the classroom and preparation of a wide range of web resources for K-12 education. While we feel that the process of EPO itself has been rewarding, it is particularly important enhance its impact by focusing on the production of high quality educational resources (illustrations, data or text) that can be (re-) used in other of educational applications. The Enduring Resources for Earth Science Education (ERESE) initiative offers such a method of archival in a digital library (NSDL) and dissemination of these materials through the use of resource matrices and rich metadata that allows discovery through web browsers.

The Ha Noi Expert Statement: recognition of maternal mental health in resource-constrained settings is essential for achieving the Millennium Development Goals.

2011-01-07

Mental health problems in women during pregnancy and after childbirth and their adverse consequences for child health and development have received sustained detailed attention in high-income countries. In contrast, evidence has only been generated more recently in resource-constrained settings.In June 2007 the United Nations Population Fund, the World Health Organization, the Key Centre for Women's Health in Society, a WHO Collaborating Centre for Women's Health and the Research and Training Centre for Community Development in Vietnam convened the first international expert meeting on maternal mental health and child health and development in resource-constrained settings. It aimed to appraise the evidence about the nature, prevalence and risks for common perinatal mental disorders in women; the consequences of these for child health and development and ameliorative strategies in these contexts.The substantial disparity in rates of perinatal mental disorders between women living in high- and low-income settings, suggests social rather than biological determinants. Risks in resource-constrained contexts include: poverty; crowded living situations; limited reproductive autonomy; unintended pregnancy; lack of empathy from the intimate partner; rigid gender stereotypes about responsibility for household work and infant care; family violence; poor physical health and discrimination. Development is adversely affected if infants lack day-to-day interactions with a caregiver who can interpret their cues, and respond effectively. Women with compromised mental health are less able to provide sensitive, responsive infant care. In resource-constrained settings infants whose mothers are depressed are less likely to thrive and to receive optimal care than those whose mothers are well.The meeting outcome is the Hanoi Expert Statement (Additional file 1). It argues that the Millennium Development Goals to improve maternal health, reduce child mortality, promote gender equality and empower women, achieve universal primary education and eradicate extreme poverty and hunger cannot be attained without a specific focus on women's mental health. It was co-signed by the international expert group; relevant WHO and UNFPA departmental representatives and international authorities. They concur that social rather than medical responses are required. Improvements in maternal mental health require a cross-sectoral response addressing poverty reduction, women's rights, social protection, violence prevention, education and gender in addition to health.

Measuring environmental efficiency of agricultural water use: a Luenberger environmental indicator.

Azad, Md A S; Ancev, Tihomir

Irrigated agriculture creates substantial environmental pressures by withdrawing large quantities of water, leaving rivers and wetlands empty and unable to support the valuable ecosystems that depend on the water resource. The key challenge facing society is that of balancing water extractions for agricultural production and other uses with provision of appropriate environmental flow to maintain healthy rivers and wetlands. Measuring tradeoffs between economic gain of water use in agriculture and its environmental pressures can contribute to constructing policy instruments for improved water resource management. The aim of this paper is to develop a modelling framework to measure these tradeoffs. Using a new approach - Luenberger environmental indicator - the study derives environmental efficiency scores for various types of irrigation enterprises across seventeen natural resource management regions within the Murray-Darling Basin, Australia. Findings show that there is a substantial variation in environmental performance of irrigation enterprises across the regions. Some enterprises were found to be relatively environmentally efficient in some regions, but they were not efficient in others. The environmental efficiency scores could be used as a guideline for formulating regional policy and strategy to achieve sustainable water use in the agricultural sector.

Human navigation is a very complex ability that encompasses all four stages of human information processing (sensory input, perception/cognition, selection, and execution of an action), involving both cognitive and physical requirements. During flight, the pilot uses all of these stages and one of the most critical aspect is interference. In fact, spatial tasks competing for the same cognitive resource cause greater distraction from a concurrent task than another task that uses different resource modalities. Here we compared and contrasted the performance of pilots and nonpilots of both genders performing increasingly complex navigational memory tasks while exposed to various forms of interference. We investigated the effects of four different sources of interference: motor, spatial motor, verbal, and spatial environment, focusing on gender differences. We found that flight experts perform better than controls (Pilots: 6.50 ± 1.29; Nonpilots: 5.45 ± 1.41). Furthermore, in the general population, navigational working memory is compromised only by spatial environmental interference (Nonpilots: 4.52 ± 1.50); female nonpilots were less able than male nonpilots. Also, the flight expert group showed the same interference, even if reduced (Pilots: 5.24 ± 0.92); moreover, we highlighted a complete absence of gender-related effects. Spatial environmental interference is the only interference producing a decrease in performance. Nevertheless, pilots are less affected than the general population. This is probably a consequence of the need to commit substantial cognitive resources to process spatial information during flight.

Water resources management: Hydrologic characterization through hydrograph simulation may bias streamflow statistics

NASA Astrophysics Data System (ADS)

Farmer, W. H.; Kiang, J. E.

2017-12-01

The development, deployment and maintenance of water resources management infrastructure and practices rely on hydrologic characterization, which requires an understanding of local hydrology. With regards to streamflow, this understanding is typically quantified with statistics derived from long-term streamgage records. However, a fundamental problem is how to characterize local hydrology without the luxury of streamgage records, a problem that complicates water resources management at ungaged locations and for long-term future projections. This problem has typically been addressed through the development of point estimators, such as regression equations, to estimate particular statistics. Physically-based precipitation-runoff models, which are capable of producing simulated hydrographs, offer an alternative to point estimators. The advantage of simulated hydrographs is that they can be used to compute any number of streamflow statistics from a single source (the simulated hydrograph) rather than relying on a diverse set of point estimators. However, the use of simulated hydrographs introduces a degree of model uncertainty that is propagated through to estimated streamflow statistics and may have drastic effects on management decisions. We compare the accuracy and precision of streamflow statistics (e.g. the mean annual streamflow, the annual maximum streamflow exceeded in 10% of years, and the minimum seven-day average streamflow exceeded in 90% of years, among others) derived from point estimators (e.g. regressions, kriging, machine learning) to that of statistics derived from simulated hydrographs across the continental United States. Initial results suggest that the error introduced through hydrograph simulation may substantially bias the resulting hydrologic characterization.

While questionnaires have been developed to capture patient-reported outcomes (PROs) in rheumatology practice, these instruments are not widely used. We developed a touchscreen interface designed to provide reliable and efficient data collection. Using the touchscreen to obtain PROs, we compared 2 different workflow models implemented separately in 2 rheumatology clinics. The Plan-Do-Study-Act methodology was used in 2 cycles of workflow redesign. Cycle 1 relied on off-the-shelf questionnaire builder software, and cycle 2 relied on a custom programmed software solution. During cycle 1, clinic 1 (private practice model, resource replete, simple flow) demonstrated a high completion rate at the start, averaging between 74% and 92% for the first 12 weeks. Clinic 2 (academic model, resource deficient, complex flow) did not achieve a consistent completion rate above 60%. The revised cycle 2 implementation protocol incorporated a 15-minute "nurse visit," an instant messaging system, and a streamlined authentication process, all of which contributed to substantial improvement in touchscreen questionnaire completion rates of ∼80% that were sustained without the need for any additional clinic staff support. Process redesign techniques and touchscreen technology were used to develop a highly successful, efficient, and effective process for the routine collection of PROs in a busy, complex, and resource-depleted academic practice and in typical private practice. The successful implementation required both a touchscreen questionnaire, human behavioral redesign, and other technical solutions. Copyright © 2012 by the American College of Rheumatology.

Assessing the Health and Performance Risks of Reduced Carbon Dioxide Exposures and Resource Utilization

NASA Technical Reports Server (NTRS)

James, John T.

2012-01-01

There have been a cluster of anecdotal reports that ISS crews are experiencing adverse health effects from on orbit exposure to CO2 levels well below the current Spacecraft Maximum Allowable Concentration (SMAC), which is 5.3 mmHg for 180 days of exposure. Developing evidence that this standard should be reduced to protect crew health is not a simple process. Dr. John James' team looked at the reports of headaches by the crew during private medical conferences and matched these with CO2 levels around the time of these reports. They then compared these to CO2 levels when there were no reports of headache. Using benchmark dose modeling, they found that the risk of headache could be predicted in concentration ranges from 2 to 5 mmHg. However, the data are incomplete because there were insufficient data when crews were exposed to concentrations below 2 mmHg. James' team also asked whether neuro-cognitive effects could be identified with CO2 exposure levels and found that these could not be associated with CO2 levels. Finally, they addressed the question of resource use to meet various levels of CO2 control if the SMACs were lowered. They estimated that CO2 restrictions approaching 2 mmHg would require substantial increases in power use and up-mass resources. They are refining their data on CO2 and headaches, and are looking at potential interactions of intracranial pressure and CO2 levels in eliciting ocular effects.

Lunar base siting

Staehle, Robert L.; Dowling, Richard

1991-01-01

As with any planetary body, the lunar surface is quite heterogeneous. There are widely dispersed sites of particular interest for known and potential resource availability, selenology, and lunar observatories. Discriminating characteristics include solar illumination, view of earth, local topography, engineering properties of the regolith and certain geological features, and local mineralogy and petrology. Space vehicle arrival and departure trajectories constitute a minor consideration. Over time, a variety of base sites will be developed serving different purposes. Resource-driven sites may see the fastest growth during the first decades of lunar development, but selection of the most favorable sites is likely to be driven by suitability for a combination of activities. As on earth, later development may be driven by geographical advantages of surface transportation routes. With the availability of near-constant sunlight for power generation, as well as permanently shadowed areas at cryogenic temperatures, polar sites are attractive because they require substantially less earth-launched mass and lower equipment complexity for an initial permanent base. Discovery of accessible volatiles reservoirs, either in the form of polar permafrost or gas reservoirs at other locations, would dramatically increase the attractiveness of any site from a logistical support and selenological point of view. Amid such speculation, no reliable evidence of such volatiles exist. More reliable evidence exists for areas of certain mineral concentrations, such as ilmenite, which could form a feedstock for some proposed resource extraction schemes. While tentative selections of advantageous base sites are made, new data from lunar polar orbiters and the Galileo polar flybys would be very helpful.

Assessment of impacts of proposed coal-resource and related economic development on water resources, Yampa River basin, Colorado and Wyoming; a summary

USGS Publications Warehouse

Steele, Timothy Doak; Hillier, Donald E.

1981-01-01

Expanded mining and use of coal resources in the Rocky Mountain region of the western United States will have substantial impacts on water resources, environmental amenities, and social and economic conditions. The U.S. Geological Survey has completed a 3-year assessment of the Yampa River basin, Colorado and Wyoming, where increased coal-resource development has begun to affect the environment and quality of life. Economic projections of the overall effects of coal-resource development were used to estimate water use and the types and amounts of waste residuals that need to be assimilated into the environment. Based in part upon these projections, several physical-based models and other semiquantitative assessment methods were used to determine possible effects upon the basin's water resources. Depending on the magnitude of mining and use of coal resources in the basin, an estimated 0.7 to 2.7 million tons (0.6 to 2.4 million metric tons) of waste residuals may be discharged annually into the environment by coal-resource development and associated economic activities. If the assumed development of coal resources in the basin occurs, annual consumptive use of water, which was approximately 142,000 acre-feet (175 million cubic meters) during 1975, may almost double by 1990. In a related analysis of alternative cooling systems for coal-conversion facilities, four to five times as much water may be used consumptively in a wet-tower, cooling-pond recycling system as in once-through cooling. An equivalent amount of coal transported by slurry pipeline would require about one-third the water used consumptively by once-through cooling for in-basin conversion. Current conditions and a variety of possible changes in the water resources of the basin resulting from coal-resource development were assessed. Basin population may increase by as much as threefold between 1975 and 1990. Volumes of wastes requiring treatment will increase accordingly. Potential problems associated with ammonia-nitrogen concentrations in the Yampa River downstream from Steamboat Springs were evaluated using a waste-load assimilative-capacity model. Changes in sediment loads carried by streams due to increased coal mining and construction of roads and buildings may be apparent only locally; projected increases in sediment loads relative to historic loads from the basin are estimated to be 2 to 7 percent. Solid-waste residuals generated by coal-conversion processes and disposed of into old mine pits may cause widely dispersed ground-water contamination, based on simulation-modeling results. Projected increases in year-round water use will probably result in the construction of several proposed reservoirs. Current seasonal patterns of streamflow and of dissolvedsolids concentrations in streamflow will be altered appreciably by these reservoirs. Decreases in time-weighted mean-annual dissolved-solids concentrations of as much as 34 percent are anticipated, based upon model simulations of several configurations of proposed reservoirs. Detailed statistical analyses of water-quality conditions in the Yampa River basin were made. Regionalized maximum waterquality concentrations were estimated for possible comparison with future conditions. Using Landsat imagery and aerial photographs, potential remote-sensing applications were evaluated to monitor land-use changes and to assess both snow cover and turbidity levels in streams. The technical information provided by the several studies of the Yampa River basin assessment should be useful to regional planners and resource managers in evaluating the possible impacts of development on the basin's water resources.

Low Temperature Geothermal Resource Assessment for Membrane Distillation Desalination in the United States

DOE Office of Scientific and Technical Information (OSTI.GOV)

Akar, Sertac; Turchi, Craig

Substantial drought and declines in potable groundwater in the United States over the last decade has increased the demand for fresh water. Desalination of saline water such as brackish surface or groundwater, seawater, brines co-produced from oil and gas operations, industrial wastewater, blow-down water from power plant cooling towers, and agriculture drainage water can reduce the volume of water that requires disposal while providing a source of high-quality fresh water for industrial or commercial use. Membrane distillation (MD) is a developing technology that uses low-temperature thermal energy for desalination. Geothermal heat can be an ideal thermal-energy source for MD desalinationmore » technology, with a target range of $1/m3 to $2/m3 for desalinated water depending on the cost of heat. Three different cases were analyzed to estimate levelized cost of heat (LCOH) for integration of MD desalination technology with low-grade geothermal heat: (1) residual heat from injection brine at a geothermal power plant, (2) heat from existing underutilized low-temperature wells, and (3) drilling new wells for low-temperature resources. The Central and Western United States have important low-temperature (<90 degrees C) geothermal resource potential with wide geographic distribution, but these resources are highly underutilized because they are inefficient for power production. According to the USGS, there are 1,075 identified low temperature hydrothermal systems, 55 low temperature sedimentary systems and 248 identified medium to high temperature geothermal systems in the United States. The estimated total beneficial heat potential from identified low temperature hydrothermal geothermal systems and residual beneficial heat from medium to high temperature systems is estimated as 36,300 MWth, which could theoretically produce 1.4 to 7 million m3/day of potable water, depending on desalination efficiency.« less

Agriculture and natural resources in a changing world - the role of irrigation

NASA Astrophysics Data System (ADS)

Sauer, T.; Havlík, P.; Schneider, U. A.; Kindermann, G.; Obersteiner, M.

2009-04-01

Fertile land and fresh water constitute two of the most fundamental resources for food production. These resources are affected by environmental, political, economic, and technical developments. Regional impacts may transmit to the world through increased trade. With a global forest and agricultural sector model, we quantify the impacts of increased demand for food due to population growth and economic development on potential land and water use. In particular, we investigate producer adaptation regarding crop and irrigation choice, agricultural market adjustments, and changes in the values of land and water. Against the background of resource sustainability and food security topics, this study integrates the spatial and operational heterogeneity of irrigation management into a global land use model. It represents a first large scale assessment of agricultural water use under explicit consideration of alternative irrigation options in their particular biophysical, economic, and technical context, accounting for international trade, motivation-based farming, and quantified aggregated impacts on land scarcity, water scarcity, and food supply. The inclusion of technical and economic aspects of irrigation choice into an integrated land use modeling framework provides new insights into the interdisciplinary trade-offs between determinants of global land use change. Agricultural responses to population and economic growth include considerable increases in irrigated area and agricultural water use, but reductions in the average water intensity. Different irrigation systems are preferred under different exogenous biophysical and socioeconomic conditions. Negligence of these adaptations would bias the burden of development on land and water scarcity. Without technical progress in agriculture, predicted population and income levels for 2030 would require substantial price adjustments for land, water, and food to equilibrate supply and demand.

Location Is Everything: Evaluating the Effects of Terrestrial and Marine Resource Subsidies on an Estuarine Bivalve

PubMed Central

Harding, Joel M. S.; Segal, Michelle R.; Reynolds, John D.

2015-01-01

Estuaries are amongst the world’s most productive ecosystems, lying at the intersection between terrestrial and marine environments. They receive substantial inputs from adjacent landscapes but the importance of resource subsidies is not well understood. Here, we test hypotheses for the effects of both terrestrial- and salmon-derived resource subsidies on the diet (inferred from stable isotopes of muscle tissue), size and percent nitrogen of the soft-shell clam (Mya arenaria), a sedentary estuarine consumer. We examine how these relationships shift across natural gradients among 14 estuaries that vary in upstream watershed size and salmon density on the central coast of British Columbia, Canada. We also test how assimilation and response to subsidies vary at smaller spatial scales within estuaries. The depletion and enrichment of stable isotope ratios in soft-shell clam muscle tissue correlated with increasing upstream watershed size and salmon density, respectively. The effects of terrestrial- and salmon-derived subsidies were also strongest at locations near stream outlets. When we controlled for age of individual clams, there were larger individuals with higher percent nitrogen content in estuaries below larger watersheds, though this effect was limited to the depositional zones below river mouths. Pink salmon exhibited a stronger effect on isotope ratios of clams than chum salmon, which could reflect increased habitat overlap as spawning pink salmon concentrate in lower stream reaches, closer to intertidal clam beds. However, there were smaller clams in estuaries that had higher upstream pink salmon densities, possibly due to differences in habitat requirements. Our study highlights the importance of upstream resource subsidies to this bivalve species, but that individual responses to subsidies can vary at smaller scales within estuaries. PMID:25993002

Despite a substantial increase in hospital resources, increased hospital admissions and out-patient visits, long waiting lists have been a significant problem in Norwegian health care. A detailed analysis of the development in resource allocation and productivity at St. Olavs University Hospital in central Norway was therefore undertaken. Resource allocation and patient volume was analysed during the period 1995 to 2001. Data were analysed both for emergency and elective admissions as well as outpatient visits specified into new referrals and follow-up consultations. Full time employee equivalents for doctors and nurses increased by 36.6% and 25.9%, respectively, and all employees by 28.1%. However, admitted patients, outpatient consultations and surgical procedures only increased by 10%, 15% and 8.3%, respectively. Thus, the productivity for each hospital employee, defined as operations pr. surgeon, outpatient consultations pr. doctor etc. was significantly reduced. A striking finding was that although the number of outpatient consultations increased, the number of new referrals actually went down and the whole increase in activity at the outpatient clinics could be explained by a substantial increase in follow-up consultations. This trend was more evident in the surgical departments, where some departments actually showed a reduction in total outpatient consultations. In view of the slow increase in hospital activity in spite of a significant increase in resources, it can be speculated that patient volume might be a limiting factor for hospital activity. The health market (patient population) might not be big enough in relation to the investments in increased production capacity (equipment and manpower).

Benefits of Greenhouse Gas Mitigation on the Supply, Management, and Use of Water Resources in the United States

Climate change impacts on water resources in the U.S. are likely to be far-reaching and substantial, because the water sector spans many parts of the economy, from supply and demand for agriculture, industry, energy production, transportation and municipal use to damages from natural hazards. This paper provides impact and damage estimates from five water resource-related models in the CIRA frame work, addressing drought risk, flooding damages, water supply and demand, and global water scarcity. The four models differ in the water system assessed, their spatial scale, and the units of assessment, but together they provide a quantitative and descriptive richnessmore » in characterizing water resource sector effects of climate change that no single model can capture. The results also address the sensitivity of these estimates to greenhouse gas emission scenarios, climate sensitivity alternatives, and global climate model selection. While calculating the net impact of climate change on the water sector as a whole may be impractical, because each of the models applied here uses a consistent set of climate scenarios, broad conclusions can be drawn regarding the patterns of change and the benefits of GHG mitigation policies for the water sector. Two key findings emerge: 1) climate mitigation policy substantially reduces the impact of climate change on the water sector across multiple dimensions; and 2) the more managed the water resources system, the more tempered the climate change impacts and the resulting reduction of impacts from climate mitigation policies.« less

DNA metabarcoding of nestling feces reveals provisioning of aquatic prey and resource partitioning among Neotropical migratory songbirds in a riparian habitat.

Riparian habitats are characterized by substantial flows of emergent aquatic insects that cross the stream-forest interface and provide an important source of prey for insectivorous birds. The increased availability of prey arising from aquatic subsidies attracts high densities of Neotropical migratory songbirds that are thought to exploit emergent aquatic insects as a nestling food resource; however, the prey preferences and diets of birds in these communities are only broadly understood. In this study, we utilized DNA metabarcoding to investigate the extent to which three syntopic species of migratory songbirds-Acadian Flycatcher, Louisiana Waterthrush, and Wood Thrush-breeding in Appalachian riparian habitats (Pennsylvania, USA) exploit and partition aquatic prey subsidies as a nestling food resource. Despite substantial differences in adult foraging strategies, nearly every nestling in this study consumed aquatic taxa, suggesting that aquatic subsidies are an important prey resource for Neotropical migrants nesting in riparian habitats. While our results revealed significant interspecific dietary niche divergence, the diets of Acadian Flycatcher and Wood Thrush nestlings were strikingly similar and exhibited significantly more overlap than expected. These results suggest that the dietary niches of Neotropical migrants with divergent foraging strategies may converge due to the opportunistic provisioning of non-limiting prey resources in riparian habitats. In addition to providing the first application of DNA metabarcoding to investigate diet in a community of Neotropical migrants, this study emphasizes the importance of aquatic subsidies in supporting breeding songbirds and improves our understanding of how anthropogenic disturbances to riparian habitats may negatively impact long-term avian conservation.

Intensified Local Resource Mobilization for the Polio Eradication Initiative: The Experience of World Health Organization in Nigeria During 2008–2015

PubMed Central

Yehualashet, Yared G.; Horton, Janet; Mkanda, Pascal; Vaz, Rui G.; Afolabi, Oluwole; Gashu, Sisay G.; Banda, Richard; O'Malley, Helena; Nsubuga, Peter

Background. Since the World Health Assembly (WHA) resolved in 1988 to eradicate poliovirus, several rounds of immunization campaigns have been conducted by member states. By 2000, with the support of the Global Polio Eradication Initiative (GPEI) partners, the number of polio cases decreased by 99%. Eradicating the remaining 1% proved to be more challenging. Although the GPEI, being the largest public health project, required >$9 billion between 1988 and 2012, economic analysis showed the estimated incremental net benefits of $40 billion–$50 billion between 1988 and 2035. In 2012, the WHA declared that the completion of poliovirus eradication is a programmatic emergency for global public health. Nigeria, as one of 3 remaining polio-endemic countries, developed an emergency plan to interrupt the transmission of poliovirus. The plan included the introduction or scale-up of various new innovations and strategies, which had substantial financial implication. Methods. This is a retrospective study to document the intensified resource mobilization efforts made by the World Health Organization (WHO) in Nigeria to meet the increased financial requirements and bridge the remaining gap in funding. In addition to the established coordination platforms, the WHO Nigeria Country Office team directly engaged with national authorities, donors, and partners throughout the process of resource requirement analysis, project appraisals, proposal development, and implementation of activities, joint monitoring, and evaluation exercises. The office strengthened its capacity for direct funds disbursement and systematic implementation of a rigorous accountability framework. Results. Between 2008 and May 2015, $538 million was mobilized locally, of which 82% was mobilized since 2012. The percentage of the total funding requirements that were locally mobilized averaged 31% between 2008 and 2011 and increased to 70% between 2012 and May 2015. During the same period, the WHO Nigeria Country Office team produced and submitted 102 grant reports and facilitated >20 joint project assessment exercises. Discussion. The polio program in Nigeria has achieved unprecedented gains, despite prevailing security and operational challenges, with no case of wild poliovirus infection since July 2014. Through rigorous, transparent, and accountable funds management practice, the WHO country office in Nigeria gained donors' confidence. The locally mobilized funds have made a remarkable contribution to the successful implementation of the strategies set out in the polio emergency plan. We face the challenges of a narrow donor-base, donor fatigue, and competition among other emerging agencies joining the polio eradication initiative efforts over the last few years. We actively engage the national authorities and partners for effective coordination of the polio eradication initiative program and harmonization of resources, using the existing platforms at national, state, and local levels. We recommend strengthening the local resource mobilization machinery and broadening the donor base, to support the polio endgame strategy. Such efforts should also be adopted to support routine immunization, introduction of new vaccines, and strengthening of health systems in the country as part of polio legacy planning. PMID:26912380
