    In October 2015, the third international Pharmaceutical Pricing and Reimbursement Information (PPRI) Conference was held in Vienna to foster discussion on challenges in pricing and reimbursement policies for medicines. The research presented highlighted that commonly used pharmaceutical pricing and reimbursement policies are not sufficiently effective to address current challenges. Conference participants called for fundamental reforms to ensure access to medicines, particularly to new and potentially more effective and/or safe medicines, while safeguarding the financial sustainability of health systems and working towards universal health coverage.

    Bird, L.; Milligan, M.; Lew, D.

    2013-09-01

    In the U.S., a number of utilities are adopting higher penetrations of renewables, driven in part by state policies. While power systems have been designed to handle the variable nature of loads, the additional supply-side variability and uncertainty can pose new challenges for utilities and system operators. However, a variety of operational and technical solutions exist to help integrate higher penetrations of wind and solar generation. This paper explores renewable energy integration challenges and mitigation strategies that have been implemented in the U.S. and internationally, including forecasting, demand response, flexible generation, larger balancing areas or balancing area cooperation, and operational practices such as fast scheduling and dispatch.

    The threat of nuclear terrorism is real and poses a significant challenge to both U.S. and global security. For terrorists, the challenge is not so much the actual design of an improvised nuclear device (IND) but more the acquisition of the special nuclear material (SNM), either highly enriched uranium (HEU) or plutonium, to make the fission weapon. This paper provides two examples of technical solutions that were developed in support of the nonproliferation objective of reducing the opportunity for acquisition of HEU. The first example reviews technologies used to monitor centrifuge enrichment plants to determine if there is any diversion of uranium materials or misuse of facilities to produce undeclared product. The discussion begins with a brief overview of the basics of uranium processing and enrichment. The role of the International Atomic Energy Agency (IAEA), its safeguard objectives and how the technology evolved to meet those objectives will be described. The second example focuses on technologies developed and deployed to monitor the blend down of 500 metric tons of HEU from Russia's dismantled nuclear weapons to reactor fuel or low enriched uranium (LEU) under the U.S.-Russia HEU Purchase Agreement. This reactor fuel was then purchased by U.S. fuel fabricators and provided about half the fuel for the domestic power reactors. The Department of Energy established the HEU Transparency Program to provide confidence that weapons usable HEU was being blended down and thus removed from any potential theft scenario. Two measurement technologies, an enrichment meter and a flow monitor, were combined into an automated blend down monitoring system (BDMS) and were deployed to four sites in Russia to provide 24/7 monitoring of the blend down. Data was downloaded and analyzed periodically by inspectors to provide the assurances required.

    Introduction Nutrition transition is occurring rapidly in the world, especially in developing countries. The nutrition transition occurred in Iran very fast due to urbanization and changes in the lifestyle of people, leading to overweight and obesity. However, nutritional deficiencies are still detected due to economic factors and low nutritional knowledge. Nutrition policies do not adequately respond to the nutrition challenges in Iran. This study was conducted to evaluate and analyze the nutrition policy process challenges in Iran. Methods A qualitative study using semi-structured interviews was conducted with 59 policy makers and nutrition experts of medical universities across Iran. Interviews were continued until data saturation was achieved. Data were supplemented with surveys and documentary analysis. Thematic analysis was guided by the propositions of the stages heuristic framework. Results The results were categorized into four main themes and eight sub-themes. The main themes were 1) nutrition problem definition, 2) policy formulation, 3) implementation of the policies, and 4) evaluation of the policies. However, the multi-faceted nature of the nutritional problem makes it difficult to deal with, so a multi-sectoral approach is needed. Conclusion Nutrition policies have been implemented in Iran with varying degrees of success and with different levels of cross-sectoral collaboration. The nutrition policies sometimes have not been able to respond to the nutritional problems. One of the important reasons is that nutrition is not a priority for policy makers. Many policies suffer from a lack of adequate and appropriate resource allocation. Cooperation mechanisms to resolve nutritional problems are sometimes ineffective and inefficient. PMID:27053992

    Although heparin is an important and widely prescribed pharmaceutical anticoagulant, its high degree of sequence microheterogeneity and size polydispersity make molecular-level characterization challenging. Unlike nucleic acids and proteins that are biosynthesized through template-driven assembly processes, heparin and the related glycosaminoglycan heparan sulfate are actively remodeled during biosynthesis through a series of enzymatic reactions that lead to variable levels of O- and N-sulfonation and uronic acid epimers. As summarized in this review, heparin sequence information is determined through a bottom-up approach that relies on depolymerization reactions, size- and charge-based separations, and sensitive mass spectrometric and nuclear magnetic resonance experiments to determine the structural identity of component oligosaccharides. The structure-elucidation process, along with its challenges and opportunities for future analytical improvements, is reviewed and illustrated for a heparin-derived hexasaccharide.

    2015-01-01

    Pyoderma gangrenosum (PG) is a rare disease, but commonly related to important morbidity. PG was first assumed to be infectious, but is now considered an inflammatory neutrophilic disease, often associated with autoimmunity, and with chronic inflammatory and neoplastic diseases. Currently, many aspects of the underlying pathophysiology are not well understood, and etiology still remains unknown. PG presents as painful, single or multiple lesions, with several clinical variants, in different locations, with a non specific histology, which makes the diagnosis challenging and often delayed. In the classic ulcerative variant, characterized by ulcers with inflammatory undermined borders, a broad differential diagnosis of malignancy, infection, and vasculitis needs to be considered, making PG a diagnosis of exclusion. Moreover, there are no definitively accepted diagnostic criteria. Treatment is also challenging since, due to its rarity, clinical trials are difficult to perform, and consequently, there is no “gold standard” therapy. Patients frequently require aggressive immunosuppression, often in multidrug regimens that are not standardized. We reviewed the clinical challenges of PG in order to find helpful clues to improve diagnostic accuracy and the treatment options, namely topical care, systemic drugs, and the new emerging therapies that may reduce morbidity.

    Taenia solium neurocysticercosis (NCC) is a major cause of neurological morbidity in the world. Variability in the neuropathology and clinical presentation of NCC often make it difficult to diagnose and manage. Diagnosis of NCC can be challenging especially in endemic and resource-limited countries where laboratory and imaging techniques are often lacking. NCC management can also be challenging as current treatment options are limited and involve symptomatic agents, antiparasitic agents, or surgery. Although antiparasitic treatment probably reduces the number of active lesions and long-term seizure frequency, its efficacy is limited and strategies to improve treatment regimens are warranted. Treatment decisions should be individualized in relation to the type of NCC. Initial measures should focus on symptomatic management, with antiparasitic therapy only to be considered later on, when appropriate. Symptomatic treatment remains the cornerstone in NCC management which should not only focuses on epilepsy, but also on other manifestations that cause considerable burden (recurrent headaches, cognitive decline). Accurate patients’ categorization, better antiparasitic regimens, and definition of new clinical outcomes for trials on NCC could improve management quality and prognosis of NCC. Prevention strategies targeting tapeworm carriers and infected pigs are yielding good results in local models. If local elimination of transmission is confirmed and replicated, this will open the door to cysticercosis eradication efforts worldwide. PMID:26527895

    The present position paper addresses contemporary waste management options, weaknesses and opportunities faced by Hellenic local authorities. It focuses on state-of-the-art, tested as well as innovative, environmental management tools on a municipal scale and identifies a range of different collaboration schemes between local authorities and related service providers. Currently, a policy implementation gap is still experienced among Hellenic local authorities; it appears that administration at the local level is inadequate to manage and implement many of the general policies proposed; identify, collect, monitor and assess relevant data; and safeguard efficient and effective implementation of MSWM practices in the framework of integrated environmental management as well. This shortfall is partly due to the decentralisation of waste management issues to local authorities without a parallel substantial budgetary and capacity support, thus resulting in local activity remaining often disoriented and isolated from national strategies, therefore yielding significant planning and implementation problems and delays against pressing issues at hand as well as loss or poor use of available funds. This paper develops a systemic approach for MSWM at both the household and the non-household level, summarizes state-of-the-art available tools and compiles a set of guidelines for developing waste management master plans at the municipal level. It aims to provide a framework in the MSWM field for municipalities in Greece as well as other countries facing similar problems under often comparable socioeconomic settings.

    Finland is a country of high indoor radon concentrations. Since 1980 the authority regulations, guidance, radon mapping and research work supporting decision making have been developed continuously. Clear regulations directed to citizens and authorities form the basis for radon policy. Active mapping work and measurement ordered by private home owners has resulted in 100.000 houses measured. National indoor radon data base forms a good basis for decision making, communication and research. The number of new houses provided with radon preventive constructions has increased remarkably. New radon campaigns has increased measurement and mitigation activity. Furher increasing of public awareness is the key challenge.

    The Hidden Cost of Nuclear Weapons The Cold War arms race drove an intense plutonium production program in the U.S. This campaign produced approximately 100 tons of plutonium over 40 years. The epicenter of plutonium production in the United States was the Hanford site, a 586 square mile reservation owned by the Department of Energy and located on the Colombia River in Southeastern Washington. Plutonium synthesis relied on nuclear reactors to convert uranium to plutonium within the reactor fuel rods. After a sufficient amount of conversion occurred, the rods were removed from the reactor and allowed to cool. They were then dissolved in an acid bath and chemically processed to separate and purify plutonium from the rest of the constituents in the used reactor fuel. The acidic waste was then neutralized using sodium hydroxide and the resulting mixture of liquids and precipitates (small insoluble particles) was stored in huge underground waste tanks. The byproducts of the U.S. plutonium production campaign include over 53 million gallons of high-level radioactive waste stored in 177 large underground tanks at Hanford and another 34 million gallons stored at the Savannah River Site in South Carolina. This legacy nuclear waste represents one of the largest environmental clean-up challenges facing the world today. The nuclear waste in the Hanford tanks is a mixture of liquids and precipitates that have settled into sludge. Some of these tanks are now over 60 years old and a small number of them are leaking radioactive waste into the ground and contaminating the environment. The solution to this nuclear waste challenge is to convert the mixture of solids and liquids into a durable material that won't disperse into the environment and create hazards to the biosphere. What makes this difficult is the fact that the radioactive half-lives of some of the radionuclides in the waste are thousands to millions of years long. (The half-life of a radioactive substance is the amount

    2015-01-01

    Hair loss is a common problem affecting both men and women. The most frequent etiology is androgenetic alopecia, but other causes of hair loss such as trauma, various dermatologic diseases, and systemic diseases can cause alopecia. The loss of hair can have profound effects on one's self esteem and emotional well-being, as one's appearance plays a role in the work place and interpersonal relationships. It is therefore not surprising that means to remedy hair loss are widely sought. Hair transplant surgery has become increasingly popular, and the results that we are able to create today are quite remarkable, providing a natural appearance when the procedure is performed well. In spite of this, hair transplant surgery is not perfect. It is not perfect because the hair transplant surgeon is still faced with challenges that prevent the achievement of optimal results. Some of these challenges include a limit to donor hair availability, hair survival, and ways to conceal any evidence of a surgical procedure having taken place. This article examines some of the most important challenges facing hair restoration surgery today and possible solutions to these challenges. PMID:26203266

    Solving the global climate crisis is a multidisciplinary challenge. The world is seeking solutions to climate change. The climate research and education community must move beyond the realm of debating the science - we MUST provide the solutions. The research community understands the science and many of the solutions very well. This project will address the specifics of solutions involving social, political and science disciplines. The content is targeted to multidisciplinary education at the senior undergraduate and graduate levels in universities and colleges. Humanity has already changed the climate and current greenhouse gas emission (GHG) projections indicate our world will warm 2-6° C within a young person's lifetime. We must coordinate societal mitigation and adaptation policies, programs and technology transformations. There is now a dramatic need for many, many highly trained multidisciplinary climate change solutions professionals that understand the complexities of the challenges and can work through the social, political and science tribulations needed to sustain communities around the world. This proposed education project: Provides an introduction to the social, political, technical, health and well-being challenges of climate change; Defines and describes the unprecedented changes to personal and community lifestyle, and consumption of energy and other resources; Examines ways and means for rapid transition of energy systems from fossil fuels to clean renewable technologies. Evaluates redevelopment of our infrastructure to withstand increasing weather extremes; Inventories possible abandonment and/or protection of infrastructure that cannot be redeveloped or reworked, particularly with respect to coastal zones where substantial populations currently live. We propose an online living textbook project. Chapter contributions will be invited from outstanding solutions research professionals from around the world. The online presence is the best means

    With steep, fast-responding river catchments, exposed coastal reaches with large tidal ranges and large population densities in some of the most at-risk areas; flood forecasting in Wales presents many varied challenges. Utilising advances in computing power and learning from best practice within the United Kingdom and abroad have seen significant improvements in recent years - however, many challenges still remain. Developments in computing and increased processing power comes with a significant price tag; greater numbers of data sources and ensemble feeds brings a better understanding of uncertainty but the wealth of data needs careful management to ensure a clear message of risk is disseminated; new modelling techniques utilise better and faster computation, but lack the history of record and experience gained from the continued use of more established forecasting models. As a flood forecasting team we work to develop coastal and fluvial forecasting models, set them up for operational use and manage the duty role that runs the models in real time. An overview of our current operational flood forecasting system will be presented, along with a discussion on some of the solutions we have in place to address the challenges we face. These include: • real-time updating of fluvial models • rainfall forecasting verification • ensemble forecast data • longer range forecast data • contingency models • offshore to nearshore wave transformation • calculation of wave overtopping

    Demodex mites are the largest and most complex organisms of the skin microflora. How they interact with the innate and adaptive immune systems is unknown. Their potential to have a pathogenic role in the causation of human skin disorders causes continued speculation. With growing interest in the microflora of human skin and its relevance to cutaneous health, the role of Demodex mites needs to be better understood. The main challenges facing scientists investigating the role of these organisms and possible solutions are reviewed under the following headings: (1) Determining the mite population in skin, (2) Transporting, extracting and imaging live mites, (3) Maintaining mites viable ex vivo and (4) Establishing methods to determine the immune response to Demodex mites and their internal contents.

  11. Rational Solutions for Challenges of the New Mellennium

    1998-08-01

    We have reviewed ten major public problems challenging our Nation as it enters the new millennium. These are defense, healthcare costs, education, aging population, energy and environment, crime, low productivity growth services, income distribution, regulations, and infrastructure. These problems share several features. First, each is so large, if it were soIved; it would have major impact on the U.S. economy. Second, each is resident in a socioeconomic system containing non-linear feedback loops and an adaptive human element. Third, each can only be solved by our political system, yet these problems are not responsive to piecemeal problem solving, the approach traditionally used by policy makers. However, unless each problem is addressed in the context of the system in which it resides, the solution maybe worse than the problem. Our political system is immersed in reams of disconnected, unintelligible information skewed by various special interests to suggest policies favoring their particular needs. Help is needed, if rational solutions that serve public interests are to be forged for these ten probIems, The simulation and modeIing tools of physical scientists, engineers, economists, social scientists, public policy experts, and others, bolstered by the recent explosive growth in massively parallel computing power, must be blended together to synthesize models of the complex systems in which these problems are resident. These models must simulate the seemingly chaotic human element inherent in these systems and support policymakers in making informed decKlons about the future. We propose altering the policy development process by incorporating more modeling, simulation and analysis to bring about a revolution in policy making that takes advantage of the revolution in engineering emerging from simulation and modeling. While we recommend major research efforts to address each of these problems, we also observe these to be very complex, highly interdependent, multi

  13. PET/MRI: challenges, solutions and perspectives.

    Herzog, Hans

    2012-12-01

    Already from the start of PET/CT integrating positron emission tomography (PET) and computed tomography (CT) in one instrument, there have been considerations how to combine PET and magnetic resonance imaging (MRI) so that their complementary abilities can be utilized in a single investigation. Since classical PET electronics fail in an even weak magnetic field and PET signal processing might disturb high-frequency signals of MRI, it soon became clear that new solutions had to be found to avoid mutual interferences. During the last fifteen years a number of different approaches towards PET/MRI for small animal imaging have been developed by research groups which together with their specific features are summarized in this review. Recently, PET/MRI for human imaging became available as well - this time by industrial initiatives. First some prototypes of BrainPET/MRI were developed followed by commercial products for simultaneous and non-simultaneous whole-body PET/MRI. Although only PET/MRI integrated in one scanner offers the full diversity of complementary multiparametric imaging, there are also promising applications of non-simultaneous sequential PET/MRI. While describing the present instrumentation for human PET/MRI, this review discusses the challenges and promises related to this new imaging technology. PMID:22925652

    2014-01-01

    Background The objective of this study was to investigate the application of the university research findings or commercialization of the biopharmaceutical knowledge in Iran and determine the challenges and propose some solutions. Results A qualitative study including 19 in-depth interviews with experts was performed in 2011 and early 2012. National Innovation System (NIS) model was employed as the study design. Thematic method was applied for the analysis. The results demonstrate that policy making, regulations and management development are considered as fundamental reasons for current commercialization practice pattern. It is suggested to establish foundation for higher level documents that would involve relating bodies and provide them operational guidelines for the implementation of commercialization incentives. Conclusions Policy, regulations and management as the most influential issue should be considered for successful commercialization. The present study, for the first time, attempts to disclose the importance of evidence input for measures in order to facilitate the commercialization process by the authorities in Iran. Overall, the NIS model should be considered and utilized as one of the effective solutions for commercialization. PMID:24568555

    Global food security will remain a worldwide concern for the next 50 years and beyond. Recently, crop yield has fallen in many areas because of declining investments in research and infrastructure, as well as increasing water scarcity. Climate change and HIV/AIDS are also crucial factors affecting food security in many regions. Although agroecological approaches offer some promise for improving yields, food security in developing countries could be substantially improved by increased investment and policy reforms.

    2014-01-01

    It is timely to consider the ethical and social questions raised by progress in pharmacogenomics, based on the current importance of pharmacogenomics for avoidance of predictable side effects of drugs, and for correct choice of medications in certain cancers. It has been proposed that the entire population be genotyped for drug-metabolizing enzyme polymorphisms, as a measure that would prevent many untoward and dangerous drug reactions. Pharmacologic treatment targeting based on genomics of disease can be expected to increase greatly in the coming years. Policy and ethical issues exist on consent for large-scale genomic pharmacogenomic data collection, public vs corporate ownership of genomic research results, testing efficacy and safety of drugs used for rare genomic indications, and accessibility of treatments based on costly research that is applicable to relatively few patients. In major psychiatric disorders and intellectual deficiency, rare and de novo deletion or duplication of chromosomal segments (copy number variation), in the aggregate, are common causes of increased risk. This implies that the policy problems of pharmacogenomics will be particularly important for the psychiatric disorders. PMID:25733960

    Industry roadmaps indicate that the introduction of Extreme Ultraviolet Lithography (EUVL) is on track for high volume manufacturing. Although, there has been significant progress in each of the individual subsets of the EUVL infrastructure, the absolute management of the process outside of the scanner and up to the point-of-exposure has been highlighted as critical requirement for the adoption of EUVL. Significant changes in the EUV system environment and mask architecture are driving a zero process tolerance level. Any unforeseen contamination introduced to the scanner environment from the EUV mask could cause considerable downtime and yield loss. Absolute mask integrity at the point-of-exposure must be guaranteed. EUV mask cleaning processes-of-record have been developed and introduced to the industry [1]. The issue is not longer "how to clean the mask" but, "how to keep it clean". With the introduction of EUVL, mask cleanliness extends out beyond the traditional mask cleaning tool. Complete control of contamination and/or particles during transportation, handling and storage will require a holistic approach to mask management. A new environment specifically for EUV mask integrity must be developed and fully tested for the sub 16nm half-pitch node introduction. The SUSS MaskTrack Pro (MTP) InSync was introduced as the solution for EUV mask integrity. SUSS demonstrated the fully automated handling of EUV masks into and out of a Dual Pod System [2]. Intrinsic cleanliness of each individual handling and storage step of the inner pod (EIP) and EUV mask inside the MTP InSync Tool was investigated and reported. A target specification of a PRP <= 0.08 as criterion for the cross contamination between EIP and the EUV reticle during handling within MTP InSync has been achieved and therefore proofing the applicability for the Dual Pod automation. Moreover an appropriate automated handling, other aspects like backside particle contamination and EIP cleanliness plays a

  20. Health Inequalities Policy in Korea: Current Status and Future Challenges

    PubMed Central

    Lee, Sang-il

    2012-01-01

    In recent years, health inequalities have become an important public health concern and the subject of both research and policy attention in Korea. Government reports, as well as many epidemiological studies, have provided evidence that a wide range of health outcomes and health-related behaviors are socioeconomically patterned, and that the magnitude of health inequalities is even increasing. However, except for the revised Health Plan 2010 targets for health equity, few government policies have explicitly addressed health inequalities. Although a number of economic and social policies may have had an impact on health inequalities, such impact has scarcely been evaluated. In this review, we describe the current status of research and policy on health inequalities in Korea. We also suggest future challenges of approaches and policies to reduce health inequalities and highlight the active and intensive engagement of many policy sectors and good evidence for interventions that will make meaningful reduction of health inequalities possible.

  1. International challenges and public policy issues.

    PubMed

    Morris, N

    1999-01-01

    The paper presents an overview of current public policy issues relating to biological standardisation and control, drawing on the extensive background material assembled for two recent international reviews, and previously published work. It identifies a number of factors which are destabilising the current system and promoting a climate for change. These include the squeeze on public sector resources, the growth in volume and complexity of biologicals, developing world needs, concerns about harmonisation and new social and ethical issues. It is argued that this situation presents important opportunities for reviewing the existing boundaries between regulatory scientists, industry, and the public, for international agreement on priorities and for harmonisation and mutual recognition. While considerable progress has already been made on these issues at national, regional and global level, there is a need for fuller international participation and the additional impetus that would come from a higher-profile commitment by governments. Such commitment will also be important for the vital questions of sustaining the scientific base and securing the resource for an effective, truly worldwide programme of standardisation and control. An international approach will also be essential in steering biologicals control through the difficult social and ethical questions of the future. WHO, in collaboration with national authorities, has a key role to play in these developments. PMID:10616188

  2. Challenges : adopting GIS for diplomacy and foreign policy

    NASA Astrophysics Data System (ADS)

    Christian, Carol

    Foreign policy and diplomacy are, by definition, location specific. GIS-related tools can be useful to decision makers and problem solvers to merge diverse data that impinges on policy issues. While to a degree, such technologies have been adopted for natural disaster response, security, and environmental studies, widespread adoption of GIS into policy tasks has been slow. Decision makers and nonexperts are reluctant to assimilate new tools into old cultures because of a number of hurdles. Yet clearly, information sharing would be advantageous and allow visualization of information and situations in a more productive environment. This presentation will touch upon some of the challenges and stimulate discussion.

    Treatment options for urological malignancies continue to increase and include endoscopic, laparoscopic, robotic, and image-guided percutaneous techniques. This ever expanding array of technically demanding management options coupled with a static training paradigm introduces challenges to training the urological oncologist of the future. Minimally invasive learning opportunities continue to evolve, and include an intensive experience during residency, postgraduate short courses or mini-apprenticeships, and full time fellowship programs. Incorporation of large animal surgery and surgical simulators may help shorten the necessary learning curve. Ultimately, programs must provide an intense hands-on experience to trainees in all minimally invasive surgical aspects for optimal training. PMID:19285236

    Bruxism is a parafunctional activity related to clenching or grinding the teeth and tooth wear can be a consequence of sleep bruxism (SB). Management of severe tooth wear due to SB is a challenging situation because of the common reduced amount of remaining dental structure and loss of vertical dimension of occlusion. Rationale for the planning of oral rehabilitation of patients with SB presenting severe tooth wear should rely on evidence-based approaches; however, few studies have discussed properties of dental materials for SB rehabilitation and how to cosmetically manage severe tooth wear. This review aimed to provide an overview into bruxism cosmetic rehabilitation and how this can be implemented with good outcomes for the patient. PMID:27217798

    Many specialists encounter and treat orbital fractures. The management of these fractures is often challenging due to the impact that they can have on vision. Acute treatment involves a thorough clinical examination and management of concomitant ocular injuries. The clinical and radiographic findings for each individual patient must then be analyzed for the need for surgical intervention. Deformity and vision impairment can occur from these injuries, and while surgery is intended to prevent these problems, it can also create them. Therefore, surgical approach and implant selection should be carefully considered. Accurate anatomic reconstruction requires complete assessment of fracture margins and proper implant contouring and positioning. The implementation of new technologies for implant shaping and intraoperative assessment of reconstruction will hopefully lead to improved patient outcomes. PMID:26604678

    Type II endoleaks are the most common endovascular complications of endovascular abdominal aortic aneurysm repair (EVAR); however, there has been a divided opinion regarding their significance in EVAR. Some advocate a conservative approach unless there is clear evidence of sac expansion, while others maintain early intervention is best to prevent adverse late outcomes such as rupture. There is a lack of level-one evidence in this challenging group of patients, and due to a low event rate of complications, large numbers of patients would be required in well-designed trials to fully understand the natural history of type II endoleak. This review will discuss the imaging, management, and outcome of patients with isolated type II endoleaks following infra-renal EVAR. PMID:27042087

    2016-01-01

    The obesity epidemic in the adult and pediatric populations affects all aspects of health care, including diagnostic imaging. With the increasing prevalence of obese and morbidly obese patients, bariatric computed tomographic (CT) imaging is becoming common in day-to-day radiology practice, and a basic understanding of the unique problems that bariatric patients pose to the imaging community is crucial in any setting. Because larger patients may not fit into conventional scanners, having a CT scanner with an adequate table load limit, a large gantry aperture, a large scan field of view, and a high-power generator is a prerequisite for bariatric imaging. Iterative reconstruction methods, high tube current, and high tube voltage can reduce the image noise that is frequently seen in bariatric CT images. Truncation artifacts, cropping artifacts, and ring artifacts frequently complicate the interpretation of CT images of larger patients. If recognized, these artifacts can be easily reduced by using the proper CT equipment, scan acquisition parameters, and postprocessing options. Lastly, because of complex contrast material dynamics, contrast material-enhanced studies of bariatric patients require special attention. Understanding how the rate of injection, the scan timing, and the total mass of iodine affect vascular and parenchymal enhancement will help to optimize contrast-enhanced studies in the bariatric population. This article familiarizes the reader with the challenges that are frequently encountered at CT imaging of bariatric patients, beginning with equipment selection and ending with a review of the most commonly encountered obesity-related artifacts and the technical considerations in the acquisition of contrast-enhanced images.

  15. Data sharing policy design for consortia: challenges for sustainability

    PubMed Central

    2014-01-01

    The field of human genomics has led advances in the sharing of data with a view to facilitating translation of research into innovations for human health. This change in scientific practice has been implemented through new policy developed by many principal investigators, project managers and funders, which has ultimately led to new forms of practice and innovative governance models for data sharing. Here, we examine the development of the governance of data sharing in genomics, and explore some of the key challenges associated with the design and implementation of these policies. We examine how the incremental nature of policy design, the perennial problem of consent, the gridlock caused by multiple and overlapping access systems, the administrative burden and the problems with incentives and acknowledgment all have an impact on the potential for data sharing to be maximized. We conclude by proposing ways in which the scientific community can address these problems, to improve the sustainability of data sharing into the future. PMID:24475754

    2014-12-01

    Sever air pollution in China has in recent years caused intensive public, media and governmental attention. Many questions need to be answered about the air pollution in China, such as how harmful is the air pollution, especially PM2.5? Why suddenly so many reports about sever air pollution, is the air in China getting more polluted? How to design a policy that can control the air pollution most efficiently? After updated the national Ambient Air Quality Standards in 2012 and included PM2.5 as one of the critical air pollutants, in 2013, Chinese central government released for the first time the "Air Pollution Prevention and Control Action Plan". The plan has set goals to reduce annual mean concentration of PM2.5 up to 25% in 2017 in different regions in China. If the ambitious goals were achieved, this could be the most significant air pollution reduction in such a short time that affects so many people in human history. To achieve these goals, however, there are enormous scientific and public policy challenges to deal with. For example: Identify the key components, size fraction of PM that have the largest health effects; and identify the sources of PM that has the most harmful effects on human health and ecosystem. Reduce the uncertainty in health risk assessment. Understand complicate chemical transformation processes in air pollution formation with intensive emissions from industry, power plant, vehicles, agriculture. Interactions between air pollution, PBL, and atmospheric circulation at different scales. The accountability, feasibility, effectiveness, and efficiency of air pollution control policies. Integrate multi-pollutant control and achieve co-benefit with climate and energy policy. Regional coordinated air pollution control. The largest challenge in China for air pollution control remains how to strength the link between science and policy.

    2014-01-01

    The article analyzes Federal funding of health policy in Brazil in the 2000s, focusing on the Ministry of Health's budget implementation. Federal spending on health was less unstable between 2000 and 2002 and has expanded since 2006. However, it fluctuated as a share of both the Gross Domestic Product and Gross National Revenue. Federal intergovernmental transfers increased, exceeding 70% in 2007. Meanwhile, the proportion of Federal investments remained low, varying from 3.4% to 6.3%. The highest absolute amount of spending was on specialized outpatient and hospital care. The decade showed a proportionally greater increase in spending on pharmaceutical care. The growing allocation of Federal funds to States in the North and Northeast, especially for primary care and epidemiological surveillance, failed to offset the sharp regional inequalities in per capita Federal spending. The main characteristics of health funding limit Federal health policy governance and pose several challenges for the Brazilian Unified National Health System. PMID:24627025

    2016-04-01

    The characterization of near-Earth-objects (NEOs) in regard to physical attributes and potential risk and impact factors presents a complex and complicates scientific and engineering challenge. The societal and policy risks and impacts are no less complex, yet are rarely considered in the same context as material properties or related factors. Further, NEO impacts are typically considered as discrete events, not as initial events in a dynamic cascading system. The objective of this contribution is to position the characterization of NEOs within the public policy process domain as a means to reflect on the science-policy nexus in regard to risks and multi-hazard impacts associated with these hazards. This will be accomplished through, first, a brief overview of the science-policy nexus, followed by a discussion of policy process frameworks, such as agenda setting and the multiple streams model, focusing events, and punctuated equilibrium, and their application and appropriateness to the problem of NEOs. How, too, for example, does NEO hazard and risk compare with other low probability, high risk, hazards in regard to public policy? Finally, we will reflect on the implications of alternative NEO "solutions" and the characterization of the NEO "problem," and the political and public acceptance of policy alternatives as a way to link NEO science and policy in the context of the overall NH9.12 panel.

    Frail older adults are at risk for negative outcomes and are the most significant consumers of health resources across both acute and community settings. Both formal systems and families are involved in this care of frail elders. This article reviews health care issues for frail older adults and addresses the impact of frailty on the future health care system. It also presents challenges for future care, creative solutions that are currently being tested and explored, and suggestions for future nursing priorities. Challenges in the care of frail elders include: the organization and sustainability of the continuum of services, resource allocation, and cultural competence in service delivery. Creative solutions include intensive case management programs, targeting at risk older adults, partnerships with families, enhanced use of telemedicine and assistive technology, and promoting healthy aging. Nurses have the potential to improve elder health across settings through clinical practice, education, leadership, and research. PMID:12795634

    The increased incidence of obesity in the paediatric population poses significant challenges to renal transplantation. Whilst the body mass index appears to be widely used as a measure of obesity in adults, there are no standardised definitions in the paediatric population, making comparative analyses difficult. In the paediatric transplant population, obesity is associated with an increased incidence of surgical complications, diabetes, hyperlipidaemia and cardiovascular morbidity, leading to diminished graft function and impacting patient and graft survival. Management of obesity in renal transplantation requires multiple interventions starting with life-style and behavioural modification combined with medical and possibly surgical therapies, representing a unique challenge in the childhood setting. In this review we discuss the current challenges of obesity and potential solutions in the setting of paediatric transplantation. PMID:26018121

    From 2004 to 2011, the Canada-Pakistan HIV/AIDS Surveillance Project (HASP) worked with government and non-government partners in Pakistan to design and implement an HIV second generation surveillance (SGS) system. Insights into the development of scalable cost effective surveillance methodologies, implementation, use of data for HIV prevention and human rights were gained over the course of HASP. An ideal SGS system would be affordable, able to be implemented independently by local partners and produce data that could be readily applied in policy and programmes. Flexibility in design and implementation is important to ensure that any SGS system is responsive to information needs, political changes and changes in key population dynamics and HIV epidemics. HASP's mapping methodology is innovative and widely accepted as best practice, but sustainability of the SGS system it developed is a challenge. PMID:23220785

  10. Six challenges in modelling for public health policy.

    2015-03-01

    The World Health Organisation's definition of public health refers to all organized measures to prevent disease, promote health, and prolong life among the population as a whole (World Health Organization, 2014). Mathematical modelling plays an increasingly important role in helping to guide the most high impact and cost-effective means of achieving these goals. Public health programmes are usually implemented over a long period of time with broad benefits to many in the community. Clinical trials are seldom large enough to capture these effects. Observational data may be used to evaluate a programme after it is underway, but have limited value in helping to predict the future impact of a proposed policy. Furthermore, public health practitioners are often required to respond to new threats, for which there is little or no previous data on which to assess the threat. Computational and mathematical models can help to assess potential threats and impacts early in the process, and later aid in interpreting data from complex and multifactorial systems. As such, these models can be critical tools in guiding public health action. However, there are a number of challenges in achieving a successful interface between modelling and public health. Here, we discuss some of these challenges. PMID:25843392

    Physical activity (PA) parenting research has proliferated over the past decade, with findings verifying the influential role that parents play in children's emerging PA behaviors. This knowledge, however, has not translated into effective family-based PA interventions. During a preconference workshop to the 2012 International Society for Behavioral Nutrition and Physical Activity annual meeting, a PA parenting workgroup met to: (1) Discuss challenges in PA parenting research that may limit its translation, (2) identify explanations or reasons for such challenges, and (3) recommend strategies for future research. Challenges discussed by the workgroup included a proliferation of disconnected and inconsistently measured constructs, a limited understanding of the dimensions of PA parenting, and a narrow conceptualization of hypothesized moderators of the relationship between PA parenting and child PA. Potential reasons for such challenges emphasized by the group included a disinclination to employ theory when developing measures and examining predictors and outcomes of PA parenting as well as a lack of agreed-upon measurement standards. Suggested solutions focused on the need to link PA parenting research with general parenting research, define and adopt rigorous standards of measurement, and identify new methods to assess PA parenting. As an initial step toward implementing these recommendations, the workgroup developed a conceptual model that: (1) Integrates parenting dimensions from the general parenting literature into the conceptualization of PA parenting, (2) draws on behavioral and developmental theory, and (3) emphasizes areas which have been neglected to date including precursors to PA parenting and effect modifiers.

    2014-01-01

    The hazards of space radiation and their effective mitigation strategies continue to pose special science and technology challenges to NASA. It is widely accepted now that shielding space vehicles and structures will have to rely on new and innovative materials since aluminum, like all high Z materials, are poor shields against the particulate and highly ionizing nature of space radiation. Shielding solutions, motivated and constrained by power and mass limitations, couple this realization with "multifunctionality," both in design concept as well as in material function and composition. Materials endowed with effective shielding properties as well as with some degree of multi-functionality may be the kernel of the so-called "radiation-smart" structures and designs. This talk will present some of the challenges and potential mitigation ideas towards the realization of such structures and designs.

    Helicobacter pylori (H. pylori) is an important cause for gastric cancer in high risk individuals. H. pylori colonizes more than 50% of the world's population and associated peptic ulcer disease and gastric malignancy have important public health implications. It has been classified as a class I carcinogen in 1994 by the World Health Organization. Clinicians are often prompted to eliminate the infection the moment it is detected. This also, unfortunately, led to reckless use of antibiotics and reports of increasing resistance are now worldwide. Each year, many of people die from gastric cancer; thus application of effective vaccine can reduce this relatively high mortality worldwide. H. pylori can be eliminated by antibiotics but efficacy is sharply decreasing. Moreover, current therapy is also expensive and with side effects. Vaccine may be the best solution to the above problem but there are many challenges in producing such an effective therapeutic vaccine. Recently, the Chinese group published in Lancet, a single-center, randomized, phase III study of an oral recombinant vaccine (Urease B subunit fused with heat-labile enterotoxin B derived from Escherichia coli) prescribed in the Chinese children (6-15 years) without a history of H. pylori infection. This review provides an insight into this new solution for an old challenge. PMID:27602242

  15. Recession, debt and mental health: challenges and solutions

    PubMed Central

    2009-01-01

    Background During the economic downturn, the link between recession and health has featured in many countries' media, political, and medical debate. This paper focuses on the previously neglected relationship between personal debt and mental health. Aims Using the UK as a case study, this paper considers the public health challenges presented by debt to mental health. We then propose solutions identified in workshops held during the UK Government's Foresight Review of Mental Capital and Wellbeing. Results Within their respective sectors, health professionals should receive basic ‘debt first aid’ training, whilst all UK financial sector codes of practice should – as a minimum – recognise the existence of customers with mental health problems. Further longitudinal research is also needed to ‘unpack’ the relationship between debt and mental health. Across sectors, a lack of co-ordinated activity across health, money advice, and creditor organisations remains a weakness. A renewed emphasis on co-ordinated ‘debt care pathways’ and better communication between local health and advice services is needed. Discussion The relationship between debt and mental health presents a contemporary public health challenge. Solutions exist, but will require action and investment at a time of competition for funds.

    The top priorities for urban water sustainability include the provision of safe drinking water, wastewater handling for public health, and protection against flooding. However, rapidly aging infrastructure, population growth, and increasing urbanization call into question current urban water management strategies, especially in the fast-growing urban areas in Asia and Africa. We review innovative approaches in urban water management with the potential to provide locally adapted, resource-efficient alternative solutions. Promising examples include new concepts for stormwater drainage, increased water productivity, distributed or on-site treatment of wastewater, source separation of human waste, and institutional and organizational reforms. We conclude that there is an urgent need for major transdisciplinary efforts in research, policy, and practice to develop alternatives with implications for cities and aquatic ecosystems alike.

    With physical limitations imposing increasingly significant performance limitations on future generations of computing hardware, computer architects are turning to increased parallelism and specialized hardware to accelerate key applications and workloads. As a result, emerging high-performance computing (HPC) systems are much more heterogeneous than their predecessors, leading to both operational challenges and application challenges that must be overcome to effectively utilize the associated architectures. With support from the National Science Foundation, the Application Acceleration Center of Excellence (AACE) at the University of Tennessee is currently exploring the impact of the Intel® Xeon Phi™ coprocessor on computational science and engineering through the Beacon Project, an ongoing research project that encompasses the deployment and operation of an energy-efficient supercomputer and the coordination of an associated research program allowing project teams across the country to explore the applicability of the associated architecture to a variety of scientific codes and libraries. This talk presents an overview of encountered challenges along with associated solutions, highlights some of the current results of the application project teams, and summarizes many of the lessons learned through the Beacon Project to date. This material is based upon work supported by the National Science Foundation under Grant Number 1137097 and by the University of Tennessee through the Beacon Project.

    2008-05-01

    the United States are in areas where NOA is known to exist and therefore this issue takes on national significance. This ongoing national dilemma has raised public and business concerns. There has been continuing political and scientific debate and widespread miscommunication over perceived versus actual health risks, the validity of various analytical sampling and testing methods, the questionable necessity and escalating costs of remediation procedures, and the combined negative impact on numerous commercial and public interests. Thus, conflicting research and regulatory positions on the distinctions between and hazards of true asbestos and ordinary rock fragments is all that is presently available to the public until the differing scientific communities and government agencies arrive at a consensus on these issues. The risk assessment methodology and the analytical technology needed to support inferences drawn from existing research are available, but have not been organized and implemented in the manner needed to resolve the NOA controversy. There should exist nationally adopted and peer-reviewed NOA standards (developed jointly by the scientific community, health risk professionals, and government regulators) that establish: (1) a scientific basis for risk evaluation and assessment of NOA and rock fragments; (2) accepted analytical protocols for determining if NOA actually exists in a given area and for separating NOA from related non-asbestos rock fragments and single crystal minerals; and (3) effective public policies for managing NOA, minimizing potential hazards, and protecting public health. This article will review some of the key issues involved with the current NOA debate, propose improved analytical methodologies, describe potential solutions for dealing with NOA, and outline the benefits to be gained by creating a practical national NOA public policy.

    The health system in Nepal is characterized by a wide network of health facilities and community workers and volunteers. Nepal's Interim Constitution of 2007 addresses health as a fundamental right, stating that every citizen has the right to basic health services free of cost. But the reality is a far cry. Only 61.8% of the Nepalese households have access to health facilities within 30 min, with significant urban (85.9%) and rural (59%) discrepancy. Addressing barriers to health services needs urgent interventions at the population level. Recently (February 2015), the Government of Nepal formed a Social Health Security Development Committee as a legal framework to start implementing a social health security scheme (SHS) after the National Health Insurance Policy came out in 2013. The program has aimed to increase the access of health services to the poor and the marginalized, and people in hard to reach areas of the country, though challenges remain with financing. Several aspects should be considered in design, learning from earlier community-based health insurance schemes that suffered from low enrollment and retention of members as well as from a pro-rich bias. Mechanisms should be built for monitoring unfair pricing and unaffordable copayments, and an overall benefit package be crafted to include coverage of major health services including non-communicable diseases. Regulations should include such issues as accreditation mechanisms for private providers. Health system strengthening should move along with the roll-out of SHS. Improving the efficiency of hospital, motivating the health workers, and using appropriate technology can improve the quality of health services. Also, as currently a constitution drafting is being finalized, careful planning and deliberation is necessary about what insurance structure may suit the proposed future federal structure in Nepal.

    Nurses of the 21st century are unprepared to care for the increasing older adult population's mental health care needs. Nursing schools across the country struggle to identify and infuse geropsychiatric nursing content into curricula. In 2008, the John A. Hartford Foundation partnered with the American Academy of Nursing to fund a 4-year project, the Geropsychiatric Nursing Collaborative (GPNC). In 2011, four schools of nursing were selected to participate in the GPNC consultation project. This article describes two major challenges that schools currently face as they work to infuse geropsychiatric nursing content into nursing curricula and the solutions offered. Core geropsychiatric nursing competencies and content were identified to assist curriculum mapping, and examples of faculty resources for teaching about depression, dementia, and delirium were outlined. Incorporation of geropsychiatric nursing content is critical for preparing our future workforce to meet the increasing mental health care needs of older adults. PMID:24983239

    Point-of-care ultrasound (US) has become a cornerstone in the diagnosis and treatment of patients in the emergency department (ED). Despite the beneficial impact on patient care, concern exists over repeat use of probes and the role as a vector for pathogen transmission. US probes are used for various applications, with the level of infection risk, based on the Spaulding Classification, ranging from noncritical with common practice to semicritical with endocavitary probes. To date, the most closely studied organisms are Staphylococcus aureus and human papilloma virus. Current evidence does confirm probe colonization but has not established a causative role in human infection. Based on current literature, US use during invasive procedures remains an infection control concern, but routine use on intact skin does not appear to cause significant risk to patients. Various barrier methods are available, each with indications based on extent of procedure and likelihood of contact with mucosal surfaces. Additionally, chemical cleansing methods have been shown to be effective in limiting probe contamination after use. New technologies utilizing ultraviolet light are available and effective but not widely used in the ED setting. As our understanding of the critical factors in US probe cleaning and disinfection improves, it is important to assess the challenges found in our current practice and to identify potential solutions to improve practices and procedures in infection control across the spectrum of US probe use in various applications in the ED. This article serves as a summary of the current literature available on infection control topics with the utilization of point-of-care US, and discusses challenges and potential solutions to improve the current practice of probe-related infection control.

  6. Reference metrology for nanotechnology: significance, challenges and solutions

    Ukraintsev, Vladimir; Banke, Bill

    2010-08-01

    Metrology and control of critical dimensions (CD) are the keys to the nanotechnology success. Modern nanotechnology and nanometrology are largely based on knowledge earned during the last 10-20 years of semiconductor technology development. Semiconductor CD metrology entered the nanotechnology age in the late 1990's. Work on 130 nm and 90 nm node technologies led to the conclusion that precision is an insufficient metric for metrology quality assessment. Other components of measurement uncertainty (MU) must be considered: (i) sample-to-sample measurement bias variation, (ii) sampling uncertainty and (iii) sample variation induced by probe-sample interaction. The first one (sample dependent systematic error) is common for "indirect" and model-based CD metrologies such as top-down and cross-sectional scanning electron microscopy (SEM) and optical scatterometry (OCD). Unless special measures are taken, bias variation of CDSEM and OCD could exceed several nanometers. Variation of bias and, therefore, MU can be assessed only if reference metrology (RM) is employed. The choice of RM tools is very limited. The CD atomic force microscope (AFM) is one of a few available RM tools. The CDAFM provides sub-nanometer MU for a number of nanometrology applications. Significant challenges of CDAFM remain: (a) probe finite dimensions are limiting characterization of narrow high-aspect spaces; (b) probe flexibility complicates positioning control; (c) probe apex sharpness limits 3D AFM resolution; (d) lifetime of atomically sharp probes is too short; (e) adsorbates change properties and dimensions of nanometer-sized objects considerably, etc. We believe that solutions for the problems exist. In this paper we discuss role of RM in nanometrology, current RM choices, challenges of CDAFM, and potential solutions.

  7. Health in All (Foreign) Policy: challenges in achieving coherence.

    PubMed

    Labonté, Ronald

    2014-06-01

    Health in All Policies (HiAP) approach is generally perceived as an intersectoral approach to national or sub-national public policy development, such that health outcomes are given full consideration by non-health sectors. Globalization, however, has created numerous 'inherently global health issues' with cross-border causes and consequences, requiring new forms of global governance for health. Although such governance often includes both state and non-state (private, civil society) actors in agenda setting and influence, different actors have differing degrees of power and authority and, ultimately, it is states that ratify intergovernmental covenants or normative declarations that directly or indirectly affect health. This requires public health and health promotion practitioners working within countries to give increased attention to the foreign policies of their national governments. These foreign policies include those governing national security, foreign aid, trade and investment as well as the traditional forms of diplomacy. A new term has been coined to describe how health is coming to be positioned in governments' foreign policies: global health diplomacy. To become adept at this nuanced diplomatic practice requires familiarity with the different policy frames by which health might be inserted into the foreign policy deliberations, and thence intergovernmental/global governance negotiations. This article discusses six such frames (security, trade, development, global public goods, human rights, ethical/moral reasoning) that have been analytically useful in assessing the potential for greater and more health-promoting foreign policy coherence: a 'Health in All (Foreign) Policies' approach.

    2008-12-01

    Between them, the world's research programs, national institutions and corporations, especially oil and gas companies, have acquired substantial volumes of seismic reflection data. Although the vast majority are proprietary and confidential, significant data are released and available for research, including those in public data libraries. The challenge now is to maximise use of these data, by providing routes to seismic not simply on the basis of acquisition or processing attributes but via the geology they image. The Virtual Seismic Atlas (VSA: www.seismicatlas.org) meets this challenge by providing an independent, free-to-use community based internet resource that captures and shares the geological interpretation of seismic data globally. Images and associated documents are explicitly indexed by extensive metadata trees, using not only existing survey and geographical data but also the geology they portray. The solution uses a Documentum database interrogated through Endeca Guided Navigation, to search, discover and retrieve images. The VSA allows users to compare contrasting interpretations of clean data thereby exploring the ranges of uncertainty in the geometric interpretation of subsurface structure. The metadata structures can be used to link reports and published research together with other data types such as wells. And the VSA can link to existing data libraries. Searches can take different paths, revealing arrays of geological analogues, new datasets while providing entirely novel insights and genuine surprises. This can then drive new creative opportunities for research and training, and expose the contents of seismic data libraries to the world.

    The merger of the GIESim JTIDS simulation with JSAF added tactical communications modeling to JSAF, and posed several challenges that are overviewed along with solutions and lessons learned. Tactical communications play an increasingly critical role in military operations. JSAF is a large multi-forces simulation that is often employed for war-gaming, however JSAF currently does not model tactical communications. Also the merger of the JTIDS/Link-16 capabilities from GIESim with JSAF is a first step toward applying the GIESim rapid communications modeling approach to a large simulation environment. This paper addresses the physical and logical simulation architectures, modifications of HLA interfaces and internal logic, determination of mission goals and scenario development, associated network design, and component integration associated with the GIESim-JSAF merger. Both JSAF and the GIESim JTIDS simulation were modified to allow JSAF to pass a message through the JTIDS simulation. Substantial work was required to make this happen. Perhaps the greatest challenge was that JSAF did not have logic to handle tactical communications at all. Furthermore, JSAF needed to drive platform position updates into the JTIDS simulation so that accurate radio propagation calculations and correct network transmissions would occur. M&S interoperability between JSAF and the JTIDS simulation needed to be demonstrated in a way that tested interoperation and that had a quick impact on an observer. Therefore, an operationally relevant scenario was developed to demonstrate the value of adding communications modeling to JSAF. Current success and future possibilities will be presented.

    We present a two-steps synthesis route that yields nanometer size crystalline germanium in the form of a black powder. It relies on high temperature decomposition of tetraethylgermane (TEG) in organic solvents. The presence of pure germanium with diamond structure is unambiguously attested by powder XRD measurements. Low resolution TEM indicates that the particles are between {approx}5 to 30 nm in size depending on the synthesis conditions. The as-synthesized Ge powders can be stored in air for months and no oxidation occurs. The Ge powders are sparingly soluble in conventional solvents because Ge nanocrystals are likely embedded in a matrix, composed mainly of C=C, C-C, and C-H bonds. The presence of residual organic by-products impedes probing of the optical properties of the dots. Also, we discuss drawbacks and open challenges in high temperature solution synthesis of Ge nanocrystals that could also be faced in the synthesis of Si nanocrystals. Overall, our results call for a cautious interpretation of reported optical properties of Ge and Si nanocrystals obtained by high temperature solution methods.

  15. Increasing Diversity in the Sciences: a Partial Solution to the Challenge and the Benefits it Produces

    NASA Astrophysics Data System (ADS)

    Givan, A. V.

    2009-12-01

    Science is supposed to be about talent devoid of the bias’ and judgments generated by background, gender, ethnicity or any culturally determined discriminators. The scientific, academic, corporate and government communities have a vested interest in developing models, practices and policies that significantly increase the number of U.S. graduates in scientific disciplines. Additionally, it is crucial that these graduates possess the essential competencies and creative problem solving skills to compete in the current global economy. The stakeholders (corporations, researchers, educational practitioners, policymakers and funders) who have the common goal of producing highly qualified scientists must commit to collaborate in developing innovative strategies and solutions to this complex challenge. Volumes of research data from a variety of sources such the social and cognitive sciences, educational psychology, National Science Foundation and non-profit groups have been and are available for use enabling us to rise to the challenge we have been charged with, and are responsible for the outcome. A proposed solution to part of the challenge and discussion of the impacts of increasing diversity in science will be discussed in this paper. The paper will address one element of the issue - strategies for the recruitment and retention of under-represented groups in science focusing on the historical and current culture, climate and barriers encountered by minorities as they progress through the educational system and career pathways. The paper will examine the benefits of diversity to the individual and society as a whole.

    Epilepsy is one of the most common neurologic illnesses. This condition afflicts 2.9 million adults and children in the US, leading to an economic impact amounting to $15.5 billion. Despite the significant burden epilepsy places on the population, it is not very well understood. As this understanding continues to evolve, it is important for clinicians to stay up to date with the latest advances to provide the best care for patients. In the last 20 years, the US Food and Drug Administration has approved 15 new antiepileptic drugs (AEDs), with many more currently in development. Other advances have been achieved in terms of diagnostic modalities like electroencephalography technology, treatment devices like vagal nerve and deep-brain stimulators, novel alternate routes of drug administration, and improvement in surgical techniques. Specific patient populations, such as the pregnant, elderly, those with HIV/AIDS, and those with psychiatric illness, present their own unique challenges, with AED side effects, drug interactions, and medical–psychiatric comorbidities adding to the conundrum. The purpose of this article is to review the latest literature guiding the management of acute epileptic seizures, focusing on the current challenges across different practice settings, and it discusses studies in various patient populations, including the pregnant, geriatric, those with HIV/AIDS, comatose, psychiatric, and “pseudoseizure” patients, and offers possible evidence-based solutions or the expert opinion of the authors.

    Epilepsy is one of the most common neurologic illnesses. This condition afflicts 2.9 million adults and children in the US, leading to an economic impact amounting to $15.5 billion.

    India has compelling need and keen aspirations for indigenous clinical research. Notwithstanding this need and previously reported growth the expected expansion of Indian clinical research has not materialized. We reviewed the scientific literature, lay press reports, and ClinicalTrials.gov data for information and commentary on projections, progress, and impediments associated with clinical trials in India. We also propose targeted solutions to identified challenges. The Indian clinical trial sector grew by (+) 20.3% CAGR (compound annual growth rate) between 2005 and 2010 and contracted by (-) 14.6% CAGR between 2010 and 2013. Phase-1 trials grew by (+) 43.5% CAGR from 2005–2013, phase-2 trials grew by (+) 19.8% CAGR from 2005–2009 and contracted by (-) 12.6% CAGR from 2009–2013, and phase-3 trials grew by (+) 13.0% CAGR from 2005–2010 and contracted by (-) 28.8% CAGR from 2010–2013. This was associated with a slowing of the regulatory approval process, increased media coverage and activist engagement, and accelerated development of regulatory guidelines and recuperative initiatives. We propose the following as potential targets for restorative interventions: Regulatory overhaul (leadership and enforcement of regulations, resolution of ambiguity in regulations, staffing, training, guidelines, and ethical principles [e.g., compensation]).Education and training of research professionals, clinicians, and regulators.Public awareness and empowerment. After a peak in 2009-2010, the clinical research sector in India appears to be experiencing a contraction. There are indications of challenges in regulatory enforcement of guidelines; training of clinical research professionals; and awareness, participation, partnership, and the general image amongst the non-professional media and public. Preventative and corrective principles and interventions are outlined with the goal of realizing the clinical research potential in India. PMID:25590017

    2015-01-01

    Objective: The quality medical laboratory services play a vital role in healthcare systems. Iran has set national standards based on the international standard ISO15189. These standards came into force in September 2007. Given the important role of both laboratories professional and assessors in the standardization, this study aims to compare and analyze medical laboratory directors’ and assessors’ opinions about this process, its challenges and relevant solutions. Methods: This qualitative study was conducted on two populations in 2013. The first survey population consisted of 150 assessors. The second group consisted of directors working in medical laboratory settings. From all universities of medical sciences, 258 medical laboratories were randomly selected. Data were gathered using two open-ended questionnaires and analyzed using the thematic analysis. Results: Challenges and relevant solutions regarding the standardization and standards, the assessment process and assessor, laboratories, external entities and contextual factors across laboratories directors and assessors were derived and compared. Both groups had a positive attitude towards the standardization process. However, they expressed some concerns regarding the process and accordingly proposed solutions to overcome the challenges. Conclusion: This study provides insights into the challenges and solutions of the standardization from two professional groups’ viewpoint. These two factors are closely related and should be considered when implementing standards since a positive perception of them increases the likelihood of successful standardization. Similarities and divergences regarding challenges and solutions of the standardization, in turn, can provide insights into how this process can be improved and deserve policy makers’ attention to continue the progress.

    Brown, M.A.

    1996-12-31

    This paper describes results of evaluation of the Energy-Related Inventions Program (ERIP), focusing on the methodological challenges faced by the evaluators and solutions implemented. Operated jointly by US DOE and NIST, ERIP is one of the longest running commercialization assistance programs in US. The evaluation suggest that ERIP is a cost-effective federal investment. By the end of 1994, 24% of ERIP technologies had entered the market, producing total cumulative sales of $961 million (1994 dollars). With $124 million in program appropriations 1975-94, ERIP has an 8:1 return. At least 757 job-years were directly supported by ERIP technologies in 1994, and 6, 646 job-years of employment have been created over the past decade. The sales and employment supported by ERIP technologies are associated with $4.4 million in 1994 federal tax returns. Many issues must be addressed to fairly appraise public investments in technology commercialization programs, such as the need to track the program participants for extended periods, complexities in accounting for spinoff technologies, determining the validity of program evaluations, and dealing with performance data that are dominated by a small number of highly successful technologies.

    Under the new REACH system, companies importing, producing and marketing chemical substances will be obliged to register the single substances and to carry out a safety assessment for all identified uses during the life cycle of the substance. This duty will apply to about 10,000 existing substances in the EU market exceeding an annual production or import volume of 10 t per company. If the substance is already known to be dangerous or turns out to be dangerous(1) during the hazard assessment, the registrant is obliged to carry out an exposure assessment and a risk characterisation for all identified uses. The goal of the safety assessment is to define the conditions of use that allow for adequate control of risk with regard to health and safety at the work place, consumer safety and protection of the environment. Once the registrant has established and documented these conditions in the Chemicals Safety Report (CSR), that information is to be communicated down the supply chain by means of the Extended Safety Data Sheet (eSDS). The ultimate aim of the new legislation is to establish duties and mechanisms that systematically prevent or limit exposure to dangerous industrial chemicals. The current paper explains this concept with regard to environmental exposure and highlights the challenges and possible solutions. PMID:18000528

    Extended communication and advanced cooperation in a permanently growing healthcare and welfare domain require a well-defined set of security services provided by an interoperable security infrastructure based on international and European standards. Any communication and collaboration procedure requires a purpose. But such legal purpose-binding is definitely not the only aspect to carefully be observed and investigated. More and more, aspects of security, safety, privacy, ethics, and quality reach importance while discussing about future-proof health information systems and health networks - regardless whether local, regional or even pan-European networks. During the course of the current paradigm change from an organization-centered to a process-related and to a person-centered health system, different new technologies including mobile solutions need to be applied in order to meet challenges arising from both legal and technical circumstances. Beside the typical Information and Communication Technology systems and applications, the extended use of modern technologies includes large medical devices like, e.g., MRI and CT but also small devices like sensors worn by a person or included in clothing. Security and safety are on top of the priority list. The paper addresses the identification of some specific aspects like mobile technology and safety when moving both IT and people towards mobile health aiming at increasing citizens and patients awareness, confidence, and acceptance in future mobile care - a world often still beyond the horizon.

    I worked for physicist and Congressman Bill Foster (D-IL) as the Mather Public Policy Intern through the American Institute of Physics and the Society of Physics Students during the summer of 2014. This internship is meant to connect undergraduate physics students with the policy process in Washington DC. As a Mather Public Policy Intern, I worked for Congressman Foster researching policy initiatives such as science funding, STEM education, and environmental regulations. This talk will discuss my experience and many of the things that I learned as an undergraduate physicist working on Capitol Hill. For example, through my experience with the internship, I attended lectures and hearings that illuminated for me how members of Congress conceive of scientific research. I also met with many physicists on Capitol Hill working to improve government interest in physics research -- AAAS Fellows, Members of Congress, and Government Relations Specialists -- and I will talk about how I saw physicists impacting governmental policies relating to scientific research and development. This internship is part of the Society of Physics Students internship program and was funded by the John and Jane Mather Foundation for Science and the Arts.

    Electronic health data sets, including electronic health records (EHR) and other administrative databases, are rich data sources that have the potential to help answer important questions about the effects of clinical interventions as well as policy changes. However, analyses using such data are almost always non-experimental, leading to concerns that those who receive a particular intervention are likely different from those who do not, in ways that may confound the effects of interest. This paper outlines the challenges in estimating causal effects using electronic health data, and offers some solutions, with particular attention paid to propensity score methods that help ensure comparisons between similar groups. The methods are illustrated with a case study describing the design of a study using Medicare and Medicaid administrative data to estimate the effect of the Medicare Part D prescription drug program among individuals with serious mental illness.

    Research has delivered remarkable benefits for cancer patients and their families since James Watson and Francis Crick wrote the now immortal line, ‘We wish to propose a structure for the salt of deoxyribonucleic acid’ thus setting the molecular foundations for the modern era of cancer control. The pace of technological innovation from fundamental scientific discoveries to the policy impact of huge population studies has been breathtaking. One has only to contrast a paper on the treatment of solid epithelial cancers written by Henri Tagnon and colleagues in 1966 (Eur J Cancer 2 51–7) with the myriad of chemotherapeutic approaches at the oncologists disposal today. Inevitably, as the tide of research has risen so it has bought the flotsam and jetsam of regulations and policies. Some have been helpful, many pointless and too many actually harmful. Naturally, some of these regulatory and general policies (by this I mean those concerned with funding, structure and organization) have been specifically targeted at cancer research, e.g. US National Cancer Act 1971, whilst others have been a product of the general regulatory environment with indirect consequences for cancer research, e.g. EU Data Protection Directive 1995. Policy issues thus cover a vast terrain criss-crossed by complex interdependencies between scientific areas, countries S&T policies and socio-political constructs. Unfortunately, there has been little attention paid to the consequences of these policy issues from which the research community has, by and large, been passenger rather than driver. Global investment in cancer research is now at unprecedented levels. The recently published report by the European Cancer Research Managers Forum has found some 14 billion euros being annually spent worldwide on cancer research (this figure includes industry but overall probably underestimates spend by at least one billion [2]). With the ageing demographics of developed countries and the catch-up effect in

  20. Methodological challenges and solutions in auditory functional magnetic resonance imaging.

    PubMed

    Peelle, Jonathan E

    2014-01-01

    Functional magnetic resonance imaging (fMRI) studies involve substantial acoustic noise. This review covers the difficulties posed by such noise for auditory neuroscience, as well as a number of possible solutions that have emerged. Acoustic noise can affect the processing of auditory stimuli by making them inaudible or unintelligible, and can result in reduced sensitivity to auditory activation in auditory cortex. Equally importantly, acoustic noise may also lead to increased listening effort, meaning that even when auditory stimuli are perceived, neural processing may differ from when the same stimuli are presented in quiet. These and other challenges have motivated a number of approaches for collecting auditory fMRI data. Although using a continuous echoplanar imaging (EPI) sequence provides high quality imaging data, these data may also be contaminated by background acoustic noise. Traditional sparse imaging has the advantage of avoiding acoustic noise during stimulus presentation, but at a cost of reduced temporal resolution. Recently, three classes of techniques have been developed to circumvent these limitations. The first is Interleaved Silent Steady State (ISSS) imaging, a variation of sparse imaging that involves collecting multiple volumes following a silent period while maintaining steady-state longitudinal magnetization. The second involves active noise control to limit the impact of acoustic scanner noise. Finally, novel MRI sequences that reduce the amount of acoustic noise produced during fMRI make the use of continuous scanning a more practical option. Together these advances provide unprecedented opportunities for researchers to collect high-quality data of hemodynamic responses to auditory stimuli using fMRI. PMID:25191218

    Summary Background The volume of data, the velocity with which they are generated, and their variety and lack of structure hinder their use. This creates the need to change the way information is captured, stored, processed, and analyzed, leading to the paradigm shift called Big Data. Objectives To describe the challenges and possible solutions for developing countries when implementing Big Data projects in the health sector. Methods A non-systematic review of the literature was performed in PubMed and Google Scholar. The following keywords were used: “big data”, “developing countries”, “data mining”, “health information systems”, and “computing methodologies”. A thematic review of selected articles was performed. Results There are challenges when implementing any Big Data program including exponential growth of data, special infrastructure needs, need for a trained workforce, need to agree on interoperability standards, privacy and security issues, and the need to include people, processes, and policies to ensure their adoption. Developing countries have particular characteristics that hinder further development of these projects. Conclusions The advent of Big Data promises great opportunities for the healthcare field. In this article, we attempt to describe the challenges developing countries would face and enumerate the options to be used to achieve successful implementations of Big Data programs. PMID:25123719

    The case for undertaking policy analysis has been made by a number of scholars and practitioners. However, there has been much less attention given to how to do policy analysis, what research designs, theories or methods best inform policy analysis. This paper begins by looking at the health policy environment, and some of the challenges to researching this highly complex phenomenon. It focuses on research in middle and low income countries, drawing on some of the frameworks and theories, methodologies and designs that can be used in health policy analysis, giving examples from recent studies. The implications of case studies and of temporality in research design are explored. Attention is drawn to the roles of the policy researcher and the importance of reflexivity and researcher positionality in the research process. The final section explores ways of advancing the field of health policy analysis with recommendations on theory, methodology and researcher reflexivity. PMID:18701552

    1997-02-01

    ACORD, a consortium of 11 nongovernmental organizations from Europe, Asia, and North America devoted to poverty alleviation in Africa, formally adopted a gender policy in 1990 aimed at reducing gender-based inequities in communities where ACORD works. A 1994-96 survey of field programs indicated that the greatest gains for women had been recorded in the areas of welfare, access to resources, conscientization (awareness of and will to alter gender inequalities), and, to a lesser extent, participation; minimal progress was noted in shifting the prevailing gender-based imbalance of power and control in public or private spheres. The research identified several programming and organizational strategies that have promoted positive outcomes for women: gender-awareness training for staff and community members, working with mixed groups, working with women-only groups, promotion of female leadership, gender-aware participatory planning and evaluation, spreading responsibility throughout the organization for implementing the gender policy, recruitment and promotion of women staff, networks for women staff, and direct field involvement in research. Also identified were internal and external factors that weakened policy implementation: a lack of clarity as to its aims, culture-based resistance, confusion regarding responsibilities and procedures, weak accountability mechanisms, lack of gender impact indicators, training inadequacies, underrepresentation of women staff, and inadequate resources. As a result of the review process, ACORD has given gender issues centrality in its current 5-year strategic plan. PMID:12320739

    The methodologies, creativity and intellectual capacity of today's physicists are becoming more and more relevant in the world of policy and politics. Some issues such as climate change, alternative energy and avian influenza clearly reveal the relevance of scientific knowledge and research in policy. However, the connection between science and issues such as electronic voting, government earmarks and international cooperation are not as obvious, but the role of scientists in these topics and their effects on science itself are critical. As the world becomes increasingly technological and global, the need for the involvement of scientists in the political process grows. The traditional scientific training of physicists emphasizes intense scrutiny of specific physical phenomena in the natural world but often misses the opportunity to utilize trained scientific minds on some of society's greatest problems. I will discuss the many ways in which scientists can contribute to society far beyond the academic community and the unique opportunities science policy work offers to the socially conscious scientist or even those just looking to get more grant money.

    Development of an earthquake early warning capability and pilot project were objectives of TriNet, a 5-year (1997-2001) FEMA-funded project to develop a state-of-the-art digital seismic network in southern California. In parallel with research to assemble a protocol for rapid analysis of earthquake data and transmission of a signal by TriNet scientists and engineers, the public policy, communication and educational issues inherent in implementation of an earthquake early warning system were addressed by TriNet's outreach component. These studies included: 1) a survey that identified potential users of an earthquake early warning system and how an earthquake early warning might be used in responding to an event, 2) a review of warning systems and communication issues associated with other natural hazards and how lessons learned might be applied to an alerting system for earthquakes, 3) an analysis of organization, management and public policy issues that must be addressed if a broad-based warning system is to be developed and 4) a plan to provide earthquake early warnings to a small number of organizations in southern California as an experimental prototype. These studies provided needed insights into the social and cultural environment in which this new technology will be introduced, an environment with opportunities to enhance our response capabilities but also an environment with significant barriers to overcome to achieve a system that can be sustained and supported. In this presentation we will address the main public policy issues that were subjects of analysis in these studies. They include a discussion of the possible division of functions among organizations likely to be the principle partners in the management of an earthquake early warning system. Drawing on lessons learned from warning systems for other hazards, we will review the potential impacts of false alarms and missed events on warning system credibility, the acceptability of fully automated

    This paper discusses how and why privatization can improve policy, not only in terms of managing production, but also in terms of regulation. Three major aspects of privatization are discussed. The importance for the environment of economic efficiency and prosperity is examined. The role of private law and a rights-based policy for controlling pollution is considered. Finally the claim that privatization would replace farsighted government decisions with shortsighted decisions by owners is examined. 83 refs., 2 figs.

    . However, services are unequally distributed across the regions of the country, and the growth of the elderly population, combined with an existing treatment gap is increasing the burden on mental health care. This gap may get even wider if funding does not increase and mental health services are not expanded in the country. There is not yet a good degree of integration between primary care and the mental health teams working at CAPS level, and it is necessary to train professionals to act as mental health planners and as managers. Research on service organization, policy and mental health systems evaluation are strongly recommended in the country. There are no firm data to show the impact of such policies in terms of community service cost-effectiveness and no tangible indicators to assess the results of these policies. PMID:18775070

    Mercury is a global pollutant and presents policy challenges at local, regional, and global scales. Mercury poses risks to the health of people, fish, and wildlife exposed to elevated levels of mercury, most commonly from the consumption of methylmercury in marine and estuarine fish. The patchwork of current mercury abatement efforts limits the effectiveness of national and multi-national policies. This paper provides an overview of the major policy challenges and opportunities related to mercury in coastal and marine environments, and highlights science and policy linkages of the past several decades. The U.S. policy examples explored here point to the need for a full life cycle approach to mercury policy with a focus on source reduction and increased attention to: (1) the transboundary movement of mercury in air, water, and biota; (2) the coordination of policy efforts across multiple environmental media; (3) the cross-cutting issues related to pollutant interactions, mitigation of legacy sources, and adaptation to elevated mercury via improved communication efforts; and (4) the integration of recent research on human and ecological health effects into benefits analyses for regulatory purposes. Stronger science and policy integration will benefit national and international efforts to prevent, control, and minimize exposure to methylmercury. PMID:22901766

    Along with rapid advances in human genomics, policies governing genomic data and clinical technologies have proliferated. Stakeholder engagement is widely lauded as an important methodology for improving clinical, scientific, and public health policy decision making. The purpose of this paper is to examine how stakeholder engagement is used to develop policies in genomics research and public health areas, as well as to identify future priorities for conducting evidence-based stakeholder engagements. We focus on exemplars in biobanking and newborn screening to illustrate a variety of current stakeholder engagement in policy-making efforts. Each setting provides an important context for examining the methods of obtaining and integrating informed stakeholder voices into the policy-making process. While many organizations have an interest in engaging stakeholders with regard to genomic policy issues, there is broad divergence with respect to the stakeholders involved, the purpose of engagements, when stakeholders are engaged during policy development, methods of engagement, and the outcomes reported. Stakeholder engagement in genomics policy development is still at a nascent stage. Several challenges of using stakeholder engagement as a tool for genomics policy development remain, and little evidence regarding how to best incorporate stakeholder feedback into policy-making processes is currently available.

    Many biobanks were established as biorepositories for biomedical research, and a number of biobanks were founded in the 1990s. The main aim of the biobank is to store and to maintain biomaterials for studying chronic disease, identifying risk factors of specific diseases, and applying personalized drug therapies. This report provides a review of biobanks, including Korean biobanks and an analysis of sample volumes, regulations, policies, and ethical issues of the biobank. Until now, the top 6 countries according to the number of large-scale biobanks are the United Kingdom, United States, Sweden, France, the Netherlands, and Italy, and there is one major National Biobank of Korea (NBK) and 17 regional biobanks in Korea. Many countries have regulations and guidelines for the biobanks, and the importance of good management of biobanks is increasing. Meanwhile, according to a first survey of 456 biobank managers in the United States, biobankers are concerned with the underuse of the samples in their repositories, which need to be advertised for researchers. Korea Biobank Network (KBN) project phase II (2013-2015) was also planned for the promotion to use biospecimens in the KBN. The KBN is continuously introducing for researchers to use biospecimens in the biobank. An accreditation process can also be introduced for biobanks to harmonize collections and encourage use of biospecimens in the biobanks. KBN is preparing an on-line application system for the distribution of biospecimens and a biobank accreditation program and is trying to harmonize the biobanks. PMID:24465232

  4. Policy challenges for the pediatric rheumatology workforce: Part I. Education and economics

    PubMed Central

    2011-01-01

    For children with rheumatic conditions, the available pediatric rheumatology workforce mitigates their access to care. While the subspecialty experiences steady growth, a critical workforce shortage constrains access. This three-part review proposes both national and international interim policy solutions for the multiple causes of the existing unacceptable shortfall. Part I explores the impact of current educational deficits and economic obstacles which constrain appropriate access to care. Proposed policy solutions follow each identified barrier. Challenges consequent to obsolete, limited or unavailable exposure to pediatric rheumatology include: absent or inadequate recognition or awareness of rheumatic disease; referral patterns that commonly foster delays in timely diagnosis; and primary care providers' inappropriate or outdated perception of outcomes. Varying models of pediatric rheumatology care delivery consequent to market competition, inadequate reimbursement and uneven institutional support serve as additional barriers to care. A large proportion of pediatrics residency programs offer pediatric rheumatology rotations. However, a minority of pediatrics residents participate. The current generalist pediatrician workforce has relatively poor musculoskeletal physical examination skills, lacking basic competency in musculoskeletal medicine. To compensate, many primary care providers rely on blood tests, generating referrals that divert scarce resources away from patients who merit accelerated access to care for rheumatic disease. Pediatric rheumatology exposure could be enhanced during residency by providing a mandatory musculoskeletal medicine rotation that includes related musculoskeletal subspecialties. An important step is the progressive improvement of many providers' fixed referral and laboratory testing patterns in lieu of sound physical examination skills. Changing demographics and persistent reimbursement disparities will require workplace innovation

    Agriculture faces many challenges to maximize yields while it is required to operate in an environmentally sustainable manner. In the present study, we analyze the major agricultural challenges identified by European farmers (primarily related to biotic stresses) in 13 countries, namely Belgium, Bulgaria, the Czech Republic, France, Germany, Hungary, Italy, Portugal, Romania, Spain, Sweden, UK and Turkey, for nine major crops (barley, beet, grapevine, maize, oilseed rape, olive, potato, sunflower and wheat). Most biotic stresses (BSs) are related to fungi or insects, but viral diseases, bacterial diseases and even parasitic plants have an important impact on yield and harvest quality. We examine how these challenges have been addressed by public and private research sectors, using either conventional breeding, marker-assisted selection, transgenesis, cisgenesis, RNAi technology or mutagenesis. Both national surveys and scientific literature analysis followed by text mining were employed to evaluate genetic engineering (GE) and non-GE approaches. This is the first report of text mining of the scientific literature on plant breeding and agricultural biotechnology research. For the nine major crops in Europe, 128 BS challenges were identified with 40% of these addressed neither in the scientific literature nor in recent European public research programs. We found evidence that the private sector was addressing only a few of these "neglected" challenges. Consequently, there are considerable gaps between farmer's needs and current breeding and biotechnology research. We also provide evidence that the current political situation in certain European countries is an impediment to GE research in order to address these agricultural challenges in the future. This study should also contribute to the decision-making process on future pertinent international consortia to fill the identified research gaps. PMID:26133365

    Malawi is a Sub-Saharan African country experiencing the epidemiological transition from predominantly infectious to noncommunicable diseases (NCDs) with dramatically increasing prevalence of lifestyle-related diseases such as obesity, hypertension, and diabetes. Malawi's 2011-2016 Health Sector Strategic Plan included NCDs, and an NCD Control Program was established with subsequent development of a National Action Plan for prevention and management of NCDs launched in 2013. The current study was designed to identify gaps in implementation of NCD control program policies and action plan strategies by describing current efforts toward prevention and management of NCDs in Malawi with emphasis on challenges and opportunities. Semistructured questionnaires were used to collect quantitative and qualitative data from Malawi Ministry of Health personnel (senior officers, service providers, health education officers, and nutritionists) in 10 health districts and 3 central hospitals. Frequencies were generated for quantitative data. Qualitative data were used to generate themes and most common responses. Results showed that current services focus on facility-based NCD screening and clinical services rather than active screening, prevention, and community awareness and outreach, although respondents emphasized the importance of prevention, lifestyle education, and community outreach. Respondents indicated inadequate resources for NCD services including financial capital, human resources, equipment and supplies, and transportation. While Malawi has begun to address NCDs, policy and practice implications include (a) better integration of services within the existing infrastructure with emphasis on capacity building; (b) greater implementation of planned NCD activities; (c) a stronger, more comprehensive data management system; and (d) innovative funding solutions.

    Approximately 120 new chemicals are created each year due to ever-improving industry and technology markets. Releases of new contaminants into the environment can occur during production, use and disposal of these chemicals thereby leading to potential contamination of water supply sources. Very few emerging contaminants are regulated. In addition, knowledge gaps regarding emerging contaminants include lack health effects, occurrence (either because these compounds are not measured or because concentrations are below detection limits of readily available analytical techniques) and fate and transport in the environment especially with regards to mobility and persistence. The sources of these compounds are numerous. One source is treated wastewater, which is re-injected into groundwater aquifers for indirect potable reuse purposes. Emerging compounds of concern can be classified in various classes. This presentation will focus on contaminants, which have emerged in the last 10 years including pharmaceuticals (antibiotics/drugs), personal care products (polycyclic musks), pesticides/herbicides, industrial solvents (1,4-dioxane), gasoline additives (MTBE), disinfection byproducts such as NDMA (N-nitrosodimethylamine), and inorganic compounds such as perchlorate and arsenic. This presentation will present technical, legal and legislative challenges posed by the presence of these contaminants in water. Background information including chemical's history of use, sources in the environments, nationwide occurrence, physical and chemical properties, behavior in the environment and technologies for removal from soil and water will be presented. In addition, case studies on MTBE, pharmaceuticals and personal care products, 1,4-dioxane, arsenic and NDMA will be discussed.

    Sixteen years ago, the 105th Congress, responding to the needs of 10 million children in the United States who lacked health insurance, created the State Children's Health Insurance Program (SCHIP) as part of the Balanced Budget Act of 1997. Enacted as Title XXI of the Social Security Act, the Children's Health Insurance Program (CHIP; or SCHIP as it has been known at some points) provided states with federal assistance to create programs specifically designed for children from families with incomes that exceeded Medicaid thresholds but that were insufficient to enable them to afford private health insurance. Congress provided $40 billion in block grants over 10 years for states to expand their existing Medicaid programs to cover the intended populations, to erect new stand-alone SCHIP programs for these children, or to effect some combination of both options. Congress reauthorized CHIP once in 2009 under the Children's Health Insurance Program Reauthorization Act and extended its life further within provisions of the Patient Protection and Affordable Care Act of 2010. The purpose of this statement is to review the features of CHIP as it has evolved over the 16 years of its existence; to summarize what is known about the effects that the program has had on coverage, access, health status, and disparities among participants; to identify challenges that remain with respect to insuring this group of vulnerable children, including the impact that provisions of the new Affordable Care Act will have on the issue of health insurance coverage for near-poor children after 2015; and to offer recommendations on how to expand and strengthen the national commitment to provide health insurance to all children regardless of means.

    Inappropriate corporate influence in science-based policy has been a persistent problem in the United States across multiple issue areas and through many administrations. Interference in climate change policy has been especially pervasive in recent years, with tremendous levels of corporate resources being utilized to spread misinformation on climate science and reduce and postpone regulatory action. Much of the influence exerted by these forces is concealed from public view. Better corporate disclosure laws would reveal who is influencing climate policy to policy makers, investors, and the public. Greater transparency in the political activity of corporate actors is needed to shed light on who is responsible for the misinformation campaigns clouding the discussion around climate change in the United States. Such transparency will empower diverse stakeholders to hold corporations accountable. Specific federal policy reforms can be made in order to guide the nation down a path of greater corporate accountability in climate change policy efforts.

    Diagnosis and management of myeloma in the very elderly patient is challenging. Treatment options have vastly improved for elderly myeloma patients but still require the clinician to personalize therapy. In this paper, we offer evidence-based, pragmatic advice on how to overcome six of the main challenges likely to arise: 1) diagnosis of myeloma in this age group, 2) assessment of the need for treatment, and the fitness for combination chemotherapy, 3) provision of the best quality of supportive care, 4) choice of combination chemotherapy in those fit enough for it, 5) treatment of relapsed myeloma, and 6) provision of end of life care. With an increased burden of comorbidities and a reduced resilience to treatment and its associated toxicities, the management of myeloma in this age group requires a different approach to that in younger patients to maximize both quality and length of life.

    Breast cancer in young women is relatively rare compared to breast cancer occurring in older women. Younger women diagnosed with breast cancer also tend to have a more aggressive biology and consequently a poorer prognosis than older women. In addition, they face unique challenges such as diminished fertility from premature ovarian failure, extended survivorship periods and its attendant problems, and the psychosocial impact of diagnosis, while still raising families. It is therefore imperative to recognize the unique issues that younger women face, and plan management in a multidisciplinary fashion to optimize clinical outcomes. This paper discusses the challenges of breast cancer management for young women, as well as specific issues to consider in diagnosis, treatment, and follow-up of such patients. PMID:26730210

    Ethics enforcement in psychiatry occurs at the district branch and American Psychiatric Association (APA) levels under the guidance of American Medical Association (AMA) and APA ethics documents. Subspecialty ethics consequently have no formal role in the enforcement process. This reality challenges practitioners to work according to guidelines that may not be sufficiently relevant and challenges ethics reviewers to apply frameworks not intended for the subspecialties. This article offers the theoretical and practical support to amend APA Procedures to permit formal consideration of subspecialty ethics during ethics complaints and to include forensic practitioners on panels reviewing them. This is the first step toward an integration of two conflicting models of ethics enforcement, regulatory and aspirational, that bring together specialty and subspecialty ethics. PMID:25187285

    Given the complex neuropathology Alzheimer's disease (AD), combination therapy may be necessary for effective treatment. However, scientific, pragmatic, regulatory, and business challenges need to be addressed before combination therapy for AD can become a reality. Leaders from academia and industry, along with a former member of the Food and Drug Administration and the Alzheimer's Association, have explored these challenges and here propose a strategy to facilitate proof-of-concept combination therapy trials in the near future. First, a more integrated understanding of the complex pathophysiology and progression of AD is needed to identify the appropriate pathways and the disease stage to target. Once drug candidates are identified, novel clinical trial designs and selection of appropriate outcome assessments will be needed to enable definition and evaluation of the appropriate dose and dosing regimen and determination of efficacy. Success in addressing this urgent problem will only be achieved through collaboration among multiple stakeholders. PMID:27017906

Nevertheless, policy and public decision making are the least frequently cited Broader Impacts in proposals and funded projects within NSF's Geosciences Directorate. Academic institutions can play a lead role by introducing this societal dimension of our profession to beginning students, and by enabling interdisciplinary research and promoting communication pathways for experienced career geoscientists. Within the academic environment, the public interface of the geosciences can be presented through curriculum content and creative programs. These include undergraduate minors in economics or public policy designed for scientists and engineers, and internships with policy makers. Federal research institutions and other organizations provide valuable policy-relevant experiences for students. Academic institutions have the key freedom of mission to tackle interdisciplinary research challenges at the interface of geoscience and policy. They develop long-standing relationships with research partners, including national laboratories and state geological surveys, whose work may support policy development and analysis at local, state, regional, and national levels. CSM's Payne Institute for Earth Resources awards mini-grants for teams of researchers to develop collaborative research efforts between engineering/science and policy researchers. Current work in the areas of nuclear generation and the costs of climate policy and on policy alternatives for capturing fugitive methane emissions are examples of work at the interface between the geosciences and public policy. With academic engagement, geoscientists can steward their intellectual output when non-scientists translate geoscience information and concepts into action through public policies.

    Government policies are needed when people's behaviors fail to deliver the public good. Those policies will be most effective if they can stimulate long-term changes in beliefs and norms, creating and reinforcing the behaviors needed to solidify and extend the public good.It is often the short-term acceptability of potential policies, rather than their longer-term efficacy, that determines their scope and deployment. The policy process should consider both time scales. The academy, however, has provided insufficient insight on the coevolution of social norms and different policy instruments, thus compromising the capacity of decision makers to craft effective solutions to the society's most intractable environmental problems. Life scientists could make fundamental contributions to this agenda through targeted research on the emergence of social norms. PMID:25143635

    2012-01-01

    Background Non-adherence to prescribed medication is a pervasive problem that can incur serious effects on patients’ health outcomes and well-being, and the availability of resources in healthcare systems. This study aimed to develop practical consensus-based policy solutions to address medicines non-adherence for Europe. Methods A four-round Delphi study was conducted. The Delphi Expert Panel comprised 50 participants from 14 countries and was representative of: patient/carers organisations; healthcare providers and professionals; commissioners and policy makers; academics; and industry representatives. Participants engaged in the study remotely, anonymously and electronically. Participants were invited to respond to open questions about the causes, consequences and solutions to medicines non-adherence. Subsequent rounds refined responses, and sought ratings of the relative importance, and operational and political feasibility of each potential solution to medicines non-adherence. Feedback of individual and group responses was provided to participants after each round. Members of the Delphi Expert Panel and members of the research group participated in a consensus meeting upon completion of the Delphi study to discuss and further refine the proposed policy solutions. Results 43 separate policy solutions to medication non-adherence were agreed by the Panel. 25 policy solutions were prioritised based on composite scores for importance, and operational and political feasibility. Prioritised policy solutions focused on interventions for patients, training for healthcare professionals, and actions to support partnership between patients and healthcare professionals. Few solutions concerned actions by governments, healthcare commissioners, or interventions at the system level. Conclusions Consensus about practical actions necessary to address non-adherence to medicines has been developed for Europe. These actions are also applicable to other regions. Prioritised

    Vaccines aim to improve the well-being of everyone and are seen as a public health success story in the prevention and control of communicable infections. However, decisions to use vaccinations are not without controversy, and the introduction of vaccines targeting sexually transmitted infections (STIs) is particularly contentious. In this paper we investigate the underlying policy challenges and opportunities for rolling out STI vaccines. Looking in detail at the experience of delivering HPV vaccine, we explore the lessons that can be learnt, including policy and human rights dimensions, for future STI vaccine introduction and scale up. Policies arise from the interaction of ideas, interests and institutions. In the case of HPV vaccine, ideas have been particularly contested, although interests and institutions have impacted on policy too. A review of human rights in relation to STI vaccine policies highlights the specific needs and rights of adolescents, and the paper details concepts of consent and evolving capacity which can be used to ensure that adolescents have full access to health interventions. Policy options for vaccines include mandatory approaches - and these have been utilized in some settings for HPV vaccines. The paper argues, and outlines the rationale, against adopting mandatory STI vaccine policy approaches. The paper concludes by identifying policy opportunities for introducing new vaccines targeting STIs. PMID:24606638

    2010-03-01

    In the field of genetically modified organism (GMO) diagnostics, real-time PCR has been the method of choice for target detection and quantification in most laboratories. Despite its numerous advantages, however, the lack of a true multiplexing option may render real-time PCR less practical in the face of future GMO detection challenges such as the multiplicity and increasing complexity of new transgenic events, as well as the repeated occurrence of unauthorized GMOs on the market. In this context, we recently reported the development of a novel multiplex quantitative DNA-based target amplification method, named NASBA implemented microarray analysis (NAIMA), which is suitable for sensitive, specific and quantitative detection of GMOs on a microarray. In this article, the performance of NAIMA is compared with that of real-time PCR, the focus being their performances in view of the upcoming challenge to detect/quantify an increasing number of possible GMOs at a sustainable cost and affordable staff effort. Finally, we present our conclusions concerning the applicability of NAIMA for future use in GMO diagnostics. PMID:19821160

  7. An Elegant Biosensor Molecular Beacon Probe: Challenges and Recent Solutions

    2012-01-01

    Molecular beacon (MB) probes are fluorophore- and quencher-labeled short synthetic DNAs folded in a stem-loop shape. Since the first report by Tyagi and Kramer, it has become a widely accepted tool for nucleic acid analysis and triggered a cascade of related developments in the field of molecular sensing. The unprecedented success of MB probes stems from their ability to detect specific DNA or RNA sequences immediately after hybridization with no need to wash out the unbound probe (instantaneous format). Importantly, the hairpin structure of the probe is responsible for both the low fluorescent background and improved selectivity. Furthermore, the signal is generated in a reversible manner; thus, if the analyte is removed, the signal is reduced to the background. This paper highlights the advantages of MB probes and discusses the approaches that address the challenges in MB probe design. Variations of MB-based assays tackle the problem of stem invasion, improve SNP genotyping and signal-to-noise ratio, as well as address the challenges of detecting folded RNA and DNA. PMID:24278758

    Information theoretic approaches and model averaging are increasing in popularity, but this approach can be difficult to apply to the realistic, complex models that typify many ecological and evolutionary analyses. This is especially true for those researchers without a formal background in information theory. Here, we highlight a number of practical obstacles to model averaging complex models. Although not meant to be an exhaustive review, we identify several important issues with tentative solutions where they exist (e.g. dealing with collinearity amongst predictors; how to compute model-averaged parameters) and highlight areas for future research where solutions are not clear (e.g. when to use random intercepts or slopes; which information criteria to use when random factors are involved). We also provide a worked example of a mixed model analysis of inbreeding depression in a wild population. By providing an overview of these issues, we hope that this approach will become more accessible to those investigating any process where multiple variables impact an evolutionary or ecological response.

    GaSb thermophotovoltaic cells fabricated using Molecular Beam Epitaxy (MBE) and ion implantation techniques are studied. Challenges including different defect formation mechanisms using MBE and ion-induced defects using ion implantation were investigated by cross-sectional Transmission Electron Microscopy (XTEM), X-Ray Diffraction spectroscopy (XRD) and Scanning Electron Microscopy (SEM). For MBE grown TPVs, several approaches were used to suppress defects, including substrate preparation and using different MBE reactors. For ion-implanted TPVs, different implant doses and energies were tested to minimize the crystal damage and various Rapid Thermal Anneal (RTA) process recipes were studied to maximize the crystal recovery. Large area TPV cells with 1 × 1 cm dimensions were fabricated using these techniques, then electrically and optically characterized. Ideality factors and dark saturation currents were measured and compared for various TPVs.

    The Los Alamos High-Performance Data System (HPDS) has been developed to meet data storage and data access requirements of Grand Challenge and National Security problems running in a high-performance computing environment. HPDS is a fourth-generation data storage system in which storage devices are directly connected to a network, data is transferred directly between client machines and storage devices, and software distributed on workstations provides system management and control capabilities. Essential to the success of HPDS is the ability to effectively use HIPPI networks and HIPPI-attached storage devices for high-speed data transfer. This paper focuses on the performance of the HPDS storage systems in a Cray Supercomputer environment.

    Internationally, the importance of a coordinated effort to protect both biodiversity and public health is more and more recognized. These issues are often concentrated or particularly challenging in urban areas, and therefore on-going urbanization worldwide raises particular issues both for the conservation of living natural resources and for population health strategies. These challenges include significant difficulties associated with sustainable management of urban ecosystems, urban development planning, social cohesion and public health. An important element of the challenge is the need to interface between different forms of knowledge and different actors from science and policy. We illustrate this with examples from Belgium, showcasing concrete cases of human-nature interaction. To better tackle these challenges, since 2011, actors in science, policy and the broader Belgian society have launched a number of initiatives to deal in a more integrated manner with combined biodiversity and public health challenges in the face of ongoing urbanization. This emerging community of practice in Belgium exemplifies the importance of interfacing at different levels. (1) Bridges must be built between science and the complex biodiversity/ecosystem-human/public health-urbanization phenomena. (2) Bridges between different professional communities and disciplines are urgently needed. (3) Closer collaboration between science and policy, and between science and societal practice is needed. Moreover, within each of these communities closer collaboration between specialized sections is needed.

    Bioethics in America positions itself as a totalizing discipline, capable of providing guidance to any individual within the boundaries of a health or medical setting. Yet the religiously observant or those driven by spiritual values have not universally accepted decisions made by "secular" bioethics, and as a result, religious bioethical thinkers and adherents have developed frameworks and rich counter-narratives used to fend off encroachment by policies perceived as threatening. This article uses brain death in Jewish law, the case of Jahi McMath, and vaccination refusal to observe how the religious system of ethics is presently excluded from bioethics and its implications.

    The American Geophysical Union's Focus Group (formerly Committee) on Global Environmental Change seeks to foster the interdisciplinary interactions needed for scientific study and public understanding of global environmental change. The Focus Group is exploring ways to improve communication of scientific information to policy makers, and ways to better inform the research community about relevant public policy activities. Scientific information is increasingly influential in shaping public opinion about global environmental change. Likewise, societal concerns are increasingly prominent in the development of plans for scientific study of climate change and other global environmental issues. These developments emphasize the importance of conveying scientific information without political advocacy, and of formulating public policies that include broad advancement of scientific knowledge. This presentation will discuss these challenges and opportunities using examples from recent and pending legislation relevant to climate and carbon-cycle research. Suggestions will be made for ongoing efforts to enhance communications between the research community and policy makers.

    Volatile organic compounds (VOCs) emitted to the environment highly probably result in ecological and health risks. Many biotechnologies for waste gases containing hydrophobic VOCs have been developed in recent years. However, these biological processes usually exhibit poor removal performances for hydrophobic VOCs due to the low bioavailability. This review presents an overview of enhanced removal of hydrophobic VOCs in biofilters. Mechanisms and problems relevant to the biological removal of hydrophobic VOCs are reviewed, and then solutions including the addition of surfactants, application of fungal biocatalysts, biofiltration with pretreatment, innovative bioreactors and utilization of hydrophilic compounds are discussed in detail. Future research needs are also proposed. This review provides new insights into hydrophobic VOC removal by biofiltration. PMID:27374790

    2015-01-01

    Human immunodeficiency virus (HIV) is a chronic disease associated with dyslipidemia and insulin resistance. In addition, the administration of combination antiretroviral therapy is associated with an increase in the incidence of metabolic risk factors (insulin resistance, lipoatrophy, dyslipidemia, and abnormalities of fat distribution in HIV patients). HIV dyslipidemia is a common problem, and associated with an increase in incidence of cardiovascular disease. Further challenges in the management of HIV dyslipidemia are the presence of diabetes and metabolic syndrome, nonalcoholic fatty liver disease, hypothyroidism, chronic kidney disease, the risk of diabetes associated with statin administration, age and ethnicity, and early menopause in females. Dyslipidemia in patients with HIV is different from the normal population, due to the fact that HIV increases insulin resistance and HIV treatment not only may induce dyslipidemia but also may interact with lipid-lowering medication. The use of all statins (apart from simvastatin and lovastatin) is safe and effective in HIV dyslipidemia, and the addition of ezetimibe, fenofibrate, fish oil, and niacin can be used in statin-unresponsive HIV dyslipidemia. The management of dyslipidemia and cardiovascular disease risks associated with HIV is complex, and a certain number of patients may require management in specialist clinics run by specialist physicians in lipid disorders. Future research is needed to address best strategies in the management of hyperlipidemia with HIV infection. PMID:25565897

    Insuring solar photovoltaic (PV) systems poses certain challenges. Insurance premiums, which can represent a significant part of overall costs for PV developers, can affect market competition. The market for certain types of insurance products is limited. Historical loss data is lacking, and test data for the long-term viability of PV products under real-life conditions is limited. Insurers' knowledge about PV systems and the PV industry is uneven even as the industry introduces innovative contractual structures and business models. Interviews conducted for this report with PV project developers, insurance brokers, and underwriters suggest government actions aimed at better testing, data collection, and communication could facilitate the development of a market for PV insurance products. This report identifies actions by governments, national laboratories, and other stakeholders that could accelerate the development of insurance products in support PV systems. Such actions include: increasing understanding of the solar PV industry among insurance professionals; expanding the availability of PV historical loss data; evaluating the expansion of renewable energy business classification; developing module and component testing capabilities and services offered by federal labs; and, advancing industry standards for PV system installers.

    2015-01-01

    Night Eating Syndrome (NES) is a unique disorder characterized by a delayed pattern of food intake in which recurrent episodes of nocturnal eating and/or excessive food consumption occur after the evening meal. NES is a clinically important disorder due to its relationship to obesity, its association with other psychiatric disorders, and problems concerning sleep. However, NES often goes unrecognized by both health professionals and patients. The lack of knowledge regarding NES in clinical settings may lead to inadequate diagnoses and inappropriate treatment approaches. Therefore, the proper diagnosis of NES is the most important issue when identifying NES and providing treatment for this disorder. Clinical assessment tools such as the Night Eating Questionnaire may help health professionals working with populations vulnerable to NES. Although NES treatment studies are still in their infancy, antidepressant treatments and psychological therapies can be used for optimal management of patients with NES. Other treatment options such as melatonergic medications, light therapy, and the anticonvulsant topiramate also hold promise as future treatment options. The purpose of this review is to provide a summary of NES, including its diagnosis, comorbidities, and treatment approaches. Possible challenges addressing patients with NES and management options are also discussed. PMID:25834450

    In many countries, genetically modified organisms (GMO) legislations have been established in order to guarantee the traceability of food/feed products on the market and to protect the consumer freedom of choice. Therefore, several GMO detection strategies, mainly based on DNA, have been developed to implement these legislations. Due to its numerous advantages, the quantitative PCR (qPCR) is the method of choice for the enforcement laboratories in GMO routine analysis. However, given the increasing number and diversity of GMO developed and put on the market around the world, some technical hurdles could be encountered with the qPCR technology, mainly owing to its inherent properties. To address these challenges, alternative GMO detection methods have been developed, allowing faster detections of single GM target (e.g., loop-mediated isothermal amplification), simultaneous detections of multiple GM targets (e.g., PCR capillary gel electrophoresis, microarray, and Luminex), more accurate quantification of GM targets (e.g., digital PCR), or characterization of partially known (e.g., DNA walking and Next Generation Sequencing (NGS)) or unknown (e.g., NGS) GMO.

    One of the most exciting utilizations of nuclear data is to help unlock the mysteries of the Cosmos -- the creation of the chemical elements, the evolution and explosion of stars, and the origin and fate of the Universe. There are now many nuclear data sets, tools, and other resources online to help address these important questions. However, numerous serious challenges make it important to develop strategies now to ensure a sustainable future for this work. A number of strategies are advocated, including: enlisting additional manpower to evaluate the newest data; devising ways to streamline evaluation activities; and improving communication and coordination between existing efforts. Software projects are central to some of these strategies. Examples include: creating a virtual ''pipeline'' leading from the nuclear laboratory to astrophysics simulations; improving data visualization and management to get the most science out of the existing datasets; and creating a nuclear astrophysics data virtual (online) community. Recent examples will be detailed, including the development of two first-generation software pipelines, the Computational Infrastructure for Nuclear Astrophysics for stellar astrophysics and the bigbangonline suite of codes for cosmology, and the coupling of nuclear data to sensitivity studies with astrophysical simulation codes to guide future research.

    2015-01-01

    Elderly patients frequently present with surgical emergencies to health care providers, and outcomes in this group of patients remain poor. Contributing factors include frailty, preexisting comorbidity, polypharmacy, delayed diagnosis, and lack of timely and consultant-led treatment. In this review, we address common emergency surgical presentations in the elderly and highlight the specific challenges in caring for these patients. We summarize 20 years of reports by various medical bodies that have aimed to improve the care of these patients. To improve morbidity and mortality, several aspects of care need to be addressed. These include accurate and timely preoperative assessment to identify treatable pathology and, where possible, to consider and correct age-specific disease processes. Identification of patients in whom treatment would be futile or associated with high risk is needed to avoid unnecessary interventions and to give patients and carers realistic expectations. The use of multidisciplinary teams to identify common postoperative complications and age-specific syndromes is paramount. Prevention of complications is preferable to rescue treatment due to the high proportion of patients who fail to recover from adverse events. Even with successful surgical treatment, long-term functional decline and increased dependency are common. More research into emergency surgery in the elderly is needed to improve care for this growing group of vulnerable patients. PMID:27147891

    In the consolidation of the Southern Cone Common Market (MERCOSUR), social policies are still in the embryonic stage. However, since the latter half of the 1990s there has been a speedup in the creation of institutions dedicated to such policies with the Common Market's framework. This article focuses on health policy and the broader social policy system in order to identify the reasons for the imbalance, through three movements: reconstitution of the history of the institutional construction of social policies in MERCOSUR; identification and comparison of the successive strategies for the formulation and implementation of the social integration agenda; and reflection on the current dilemmas and challenges faced by the process. According to the study, MERCOSUR operates with strategies that are difficult to mutually reconcile. On the institutional level, it follows a minimalist strategy, while on the conceptual/ discursive level it adopts a maximalist strategy for supranational unification of social policies. The fact is that it operates a minimalist social policy strategy, since it fails to bring to the field of social integration the debate and proposals on economic and social development models that could sustain the effective construction of regional social citizenship.

    Osteoporosis (OP) is a pathological condition that manifests clinically as pain, fractures, and physical disability, resulting in the loss of independence and the need for long-term care. Chronic pain is a multidimensional experience with sensory, affective, and cognitive aspects. Age can affect each of these dimensions and the pain that is experienced. In OP, chronic pain appears to have sensory characteristics and properties of nociceptive and neuropathic pain. Its evaluation and treatment thus require a holistic approach that focuses on the specific characteristics of this population. Pain management must therefore include pharmacological approaches, physiotherapy interventions, educational measures, and, in rare cases, surgical treatment. Most rehabilitative treatments in the management of patients with OP do not evaluate pain or physical function, and there is no consensus on the effects of rehabilitation therapy on back pain or quality of life in women with OP. Pharmacological treatment of pain in patients with OP is usually insufficient. The management of chronic pain in patients with OP is complicated with regard to its diagnosis, the search for reversible secondary causes, the efficacy and duration of oral bisphosphonates, and the function of calcium and vitamin D. The aim of this review is to discuss the most appropriate solutions in the management of chronic pain in OP. PMID:27099529

    Carbon storage projects are often located in close proximity to anthropogenic sources of CO2. This means that the storage site location may be near industrial power plants, mining activity, or urban centers. Proximity to these environments can present unique challenges for the seismic survey design, acquisition, and processing teams in terms of acquiring surface seismic data that meets the site characterization objectives for a CO2 storage site. Seismic surveys in urban and industrial environments may have acquisition footprints that are severely constrained by surrounding infrastructure. The acquisition crew and survey design team must work closely together in real-time to add in-fill source and receiver locations to surveys in order to ensure that high fold coverage is maintained over the survey. High levels of seismic noise may be generated by the industrial plants themselves. Local and industrial traffic, as well as electrical noise may also be a cause for concern. Near surface conditions, such as water saturated soils, unconsolidated mine tailings, and mining cavities, may accelerate attenuation of the seismic signal and become sources of noise in the survey and further impact data quality. When dealing with such conditions, the acquisition and survey design teams must stay in constant communication to optimize survey parameters to account for noise issues. In some cases, the raw data can be so contaminated with noise that no coherent signal can be seen in the data. However, the use of high density-single sensors is one of the most effective options to deal with noisy acquisition environments as this method allows the recorded noise to be sampled without aliasing so that that it can be removed from the data without impacting the seismic signal. Removing noise and optimizing the final images obtained from the data is the job of the survey design and data processing teams. A final consideration when acquiring seismic surveys in urban areas is the visibility of

    Decision models are essential tools for coastal groundwater management (CGM). A combined simulation-optimization framework is employed to develop these models. One of the main barriers in the widespread application of these models for real-world cases is their large computational burden. Recent advances in efficient computational approaches and robust optimization methods can crack this barrier. This study surveys the scientific basis of CGM to provide an overview on this subject and reviews the-state-of-the-art to clarify recent developments and to outline ideas for improving the computational performance. Key details are presented on the performance and choice of possible robust tools such as efficient evolutionary algorithms (EAs), surrogate models, and parallel processing techniques. Then, the potential challenges remaining in this context are scrutinized, demonstrating open fields for further research, which include issues related to advances in simulating and optimizing phases such as introducing new robust algorithms and considering multi-objective purposes, implementing novel and high-performance tools, considering global concerns (e.g. climate change impacts), enhancing the existing models to fit the real world, and taking into account the complexities of real-world applications (e.g. uncertainties in the modeling parameters, and data acquisition). Finally, the outcomes of the systematic review are applied to solve a real-world CGM problem in Iran, to quantitatively examine the performance of combined implementation of some of the suggested tools. It is revealed that the required computational time is considerably reduced by as much as three orders of magnitude when correct combinations of robust EAs, surrogate model, and parallelization technique are utilized.

    2015-12-01

    Three major global problems of our times are global warming, air pollution mortality and morbidity, and energy insecurity. Whereas, policy makers with the support of the public must implement solutions to these problems, it is scientists and engineers who are best equipped to evaluate technically sound, optimal, and efficient solutions. Yet, a disconnect exists between information provided by scientists and engineers and policies implemented. Part of the reason is that scientific information provided to policy makers and the public is swamped out by information provided by lobbyists and another part is the difficulty in providing information to the hundreds of millions of people who need it rather than to just a few thousand. What other ways are available, aside from issuing press releases on scientific papers, for scientists to disseminate information? Three growing methods are through social media, creative media, and storytelling. The Solutions Project is a non-profit non-governmental organization whose goal is to bring forth scientific information about 100% clean, renewable energy plans to the public, businesses, and policy makers using these and related tools. Through the use of social media, the development of engaging internet and video content, and storytelling, the group hopes to increase the dissemination of information for social good. This talk discusses the history and impacts to date of this group and its methods. Please see www.thesolutionsproject.org and 100.org for more information.

    The launch of the National Green Technology Policy (NGTP) in 2009 is a manifesto of the government's seriousness in implementing "green" initiatives for the country. Specifically for buildings, the government promotes the application of renewable energy (RE) and energy efficiency (EE) and the application of green building index. With the introduction of Low Carbon Cities Framework, Green Pass, Green Neighbourhood, Green Building Index by various agencies and organisations in Malaysia, it is time to look back and see how all these tools could come together. This paper attempts to identify the challenges in harmonising the green initiatives for policy makers toward greener environment for sustainability.

    2010-12-01

    The objective of SESPAS Report 2010 is to enhance the incorporation of the principle of Health in all Policies in public health in Spain. The fundamental principle behind this slogan is very simple: Health is strongly influenced by the environment, how we live, work, eat, walk or enjoy our leisure time. Moreover, these living conditions depend not only on individual decisions but are determined by social, cultural, economic or environmental factor. Consequently, policy decisions that influence the health of people not just those related to services or health policy, but primarily those taken in other public, private, political and civic contexts. SESPAS Report 2010 has four parts. It begins with and introductory chapter on the challenges of incorporating the principle of Health in all Policies in public health. The second part consists of several articles of reflection on the relationship between the health care system and public health. The third part focuses on cross-sectoral public health policies. The report ends with several articles on cross-cutting issues such as public health education, information, research, evaluation and ethics in public health policies. PMID:21075491

  19. Management challenges at the intersection of public policy environments and strategic decision making in public hospitals.

    Hospitals in the United States are heavily impacted by public policies that affect them. For example, Medicare and Medicaid programs account for more than half the revenue in most of the nation's almost 5,000 community hospitals, including the almost 1,100 public hospitals controlled by state and local governments (American Hospital Association, 2012). The public hospitals are especially closely aligned with and controlled by governmental entities compared with hospitals with other kinds of sponsorship. This article addresses the management challenges at the intersection of the strategic management of public hospitals and their public policy environments. Public hospitals are complicated entities designed not only to provide health services but also in many cases to play key roles in health-related research and education and to play important general economic development roles in their communities. The multi-faceted strategic decision making in these organizations is as heavily affected by their public policy environments as by their business, demographic, technological or other external environments. Effectively managing the intersection of their public policy environments and their strategic management is indeed vital for contemporary public hospitals. This article is intended to clarify certain aspects of this intersection through a description and model of the strategic activity in public hospitals and the connection between this activity and their external environments. Specific attention is focused on the concept of public policy environments and their features. Attention is also given to how managers can assess public policy environments and incorporate the results into strategic activities. PMID:23113418

    Community participation in local health has assumed a central role in the reforms of public healthcare, being increasingly associated with the issue of decentralization of the health system. The aim of this paper is to raise questions regarding the structural approaches to multicultural social policy in Chile and to analyze the results of its implementation. The article analyzes the case study of Makewe Hospital, one of the pioneering experiences of intercultural health initiative in Chile. The Makewe Hospital, which involves the indigenous community of the Mapuche, provides interesting insights to understand the dynamics of multicultural social policy and presents an example of a successful initiative that has succeeded in involving local communities in multicultural health policy. This case study discusses the effectiveness of grassroots participation in multicultural healthcare provision and presents the main strengths and challenges for the replicability of this experience in other settings.

    Improved data sharing is needed for hydrological modeling and water management that require better integration of data, information and models. Technological advances in Earth observation and Web technologies have allowed the development of Spatial Data Infrastructures (SDIs) for improved data sharing at various scales. International initiatives catalyze data sharing by promoting interoperability standards to maximize the use of data and by supporting easy access to and utilization of geospatial data. A series of recent European projects are contributing to the promotion of innovative Earth observation solutions and the uptake of scientific outcomes in policy. Several success stories involving different hydrologists' communities can be reported around the World. Gaps still exist in hydrological, agricultural, meteorological and climatological data access because of various issues. While many sources of data exists at all scales it remains difficult and time-consuming to assemble hydrological information for most projects. Furthermore, data and sharing formats remain very heterogeneous. Improvements require implementing/endorsing some commonly agreed standards and documenting data with adequate metadata. The brokering approach allows binding heterogeneous resources published by different data providers and adapting them to tools and interfaces commonly used by consumers of these resources. The challenge is to provide decision-makers with reliable information, based on integrated data and tools derived from both Earth observations and scientific models. Successful SDIs rely therefore on various aspects: a shared vision between all participants, necessity to solve a common problem, adequate data policies, incentives, and sufficient resources. New data streams from remote sensing or crowd sourcing are also producing valuable information to improve our understanding of the water cycle, while field sensors are developing rapidly and becoming less costly.

  5. Five Policy Levers To Meet The Value Challenge In Cancer Care.

    PubMed

    Callahan, Ryan; Darzi, Ara

    2015-09-01

    The burden of cancer on public finances is a serious concern for policy makers. More people are developing cancer, and as standards of care have risen, more are surviving and requiring longer-term care. Precision medicine promises better outcomes but demands commensurately higher payments for care. As both incidence and per case costs rise, we suggest that the task of expanding access to high-quality cancer care poses a "value challenge" that policies in many countries are inadequate to meet. Policy makers should respond with a new approach. We explore questions that policy makers will need to consider regarding objectives, barriers, and levers for policy development. We use transparency and accountability as cornerstones of a new approach to promote value-based decision making. Although barriers to advancing this agenda are formidable, we recommend that governments define common standards for value-based accounting; serve as information brokers for evidence development; pioneer value-based procurement of goods and services; engage in deliberative democracy in cancer care; and educate communities to facilitate knowledge sharing between communities of patients, their caretakers, and researchers.

    Very old adults are one of the fastest-growing age groups worldwide. Yet they rarely constitute a targeted group for public policies. Drawing on the results of the centenarian studies presented in this special issue, we highlight major challenges that arise from the increase of this population. We outline several promising approaches for policy makers and professionals to develop evidence-based policies and programs that are tailored to the needs of very old adults and their families. We focus our discussion on three key topics essential to life care: the importance of integrated care to meet the complex care needs of the very old; the balance between formal and informal care; and the development of suitable places for living. Besides more specific measures, we propose that policies promoting the social integration of very old adults in their communities would be particularly helpful, as these may benefit not only the very old and their families but also individuals of all ages. We conclude that the development of suitable policies addressing the needs of the very old will benefit from future investigation of cross-cultural similarities and differences in centenarians' characteristics, available services, as well as life conditions they encounter in communities and institutional contexts.

    Purpose - The purpose of this paper is to reflect on the findings of this special issue and discusses the future challenges for policy, research and society. The findings suggest that challenges emerge as a result of legitimacy deficits of both consensus and contestatory modes of public involvement in health priority setting. Design/methodology/approach - The paper draws on the discussions and findings presented in this special issue. It seeks to bring the country experiences and case studies together to draw conclusions for policy, research and society. Findings - At least two recurring themes emerge. An underlying theme is the importance, but also the challenge, of establishing legitimacy in health priority setting. The country experiences suggest that we understand very little about the conditions under which representative, or authentic, participation generates legitimacy and under which it will be regarded as insufficient. A second observation is that public participation takes a variety of forms that depend on the opportunity structures in a given national context. Given this variety the conceptualization of public participation needs to be expanded to account for the many forms of public participation. Originality/value - The paper concludes that the challenges of public involvement are closely linked to the question of how legitimate processes and decisions can be generated in priority setting. This suggests that future research must focus more narrowly on conditions under which legitimacy are generated in order to expand the understanding of public involvement in health prioritization.

  9. Challenges to the Development and Implementation of Public Policies to Achieve Animal Welfare Outcomes

    2011-01-01

    Simple Summary Many countries have enacted legislation to protect animals. In the 1800's the primary concern was to protect animals from cruelty but more recent legislative changes also seek to ensure that human beings uphold a duty of care towards those animals for which they are responsible. Today animal welfare concerns all aspects of our interaction with other animals. Although, the diversity of views in society can present challenges, the whole community needs to be engaged in the development and implementation of policies and initiatives so as to achieve sustainable improvements in animal welfare. Abstract Although there is a long-established tradition of concern for the welfare of animals, it was not until the mid 1800's that governments sought to enact legislation to protect animals from cruelty. In the 1950's, questions concerning animal welfare re-emerged and in the ensuing years have been an on-going focus of government activities. These developments occurred against a backdrop of significant social change but there are important differences in what now underpins and informs these considerations. In the formulation and implementation of public policies, governments look for a course of action that represents and protects the interests of the community; the process may be challenging with competing interests but the final determination seeks a middle ground that best meets the needs and interests of the community as a whole. When policy development concerns our relationship with other animals, the complexity of this relationship presents particular challenges not only to the formulation of policies but also to the evaluation of outcomes. Notably, the depth of feelings and diversity of views in our community reflect the complex social, cultural and personal dimensions of this relationship. The use of animals for scientific purposes remains one of the most contentious animal welfare issues primarily because when animals are used for these purposes, accepted

    Objective Latin American-trained IMGs in psychiatry face multiple challenges that go beyond their medical training. These challenges call for innovative problem-solving. Although the professional development of IMGs has been discussed in the professional literature, little is written about their experiences. In this case study report, a group of IMGs reflect on their experiences and describe how they solved challenges. Method Using cogenerative ethnography, four IMGs trained in Colombia, Dominican Republic and Mexico provided insights on their challenges and solutions while adapting to psychiatric residency training. Individual interviews, focused discussion, focus groups, and written reports were analyzed using data reduction, data display, and conclusion drawing techniques. Results We illustrate the challenges of IMG training in psychiatry using their reflections and stories. We categorized these challenges into three domains: immigration and acculturation; social adjustment; and medical training. Quotes were selected to illustrate IMGs’ challenges and coping strategies. Conclusion Some of the combined cultural, social and academic challenges of Latin American-trained IMGs in psychiatry are described. Recognizing and planning for the personal challenges of IMGs in psychiatry can enhance the transition into psychiatric training. Ultimately, improvements in IMG training converts into improved healthcare for all patients. PMID:25673899

  11. Re-thinking hate crime: fresh challenges for policy and practice.

    Chakraborti, Neil

    2015-06-01

    Hate crime has become an increasingly familiar term in recent times as the harms associated with acts of bigotry and prejudice continue to pose complex challenges for societies across the world. However, despite the greater recognition now afforded to hate crimes by scholars, policy makers and law enforcers, uncertainty continues to cloud the scope and legitimacy of existing policy frameworks. This article draws from an emerging body of inter-disciplinary scholarship and empirical research to highlight a series of important realities about hate crime victimization and perpetration that tend to remain peripheral to the process of policy formation. It suggests that the focus on particular strands of victims and particular sets of motivations has overshadowed a range of significant issues, including the experiences of "marginal" groups of victims, and the way in which identity characteristics intersect with one another--and with other situational factors and context--to leave some targets of hate crime especially vulnerable. The article calls for a more fluid and multi-layered approach to policy formation, which engages with these realities, and which maximizes the real-life value of hate crime discourse. PMID:25192703

    We formulated policies and procedures for allied health professionals (AHPs) who provide services using telehealth in Nunavut, Canada's newest Arctic territory. These are a supplement to the clinical policies and procedures already established for Nunavut physicians and nurses. The services were in the areas of audiology, dietetics/nutrition, midwifery, occupational therapy, ophthalmic services, pharmacy, physiotherapy, psychology, respiratory therapy, social work and speech therapy. Documents specific to each of the services were developed, drawing on information from Government of Nunavut data, Nunavut healthcare providers and links made through the Internet. Topics included the scope and limitations of telehealth services, staff responsibilities, training and reporting, professional standards and cultural considerations. We also considered generic policies covering common issues such as jurisdiction, licensing and liability. The policies and procedures for AHPs will enhance and expand the successes already achieved with telehealth in Nunavut. The challenges are to balance the preferred approaches to service provision with the realities of health care and communications in an Arctic setting. PMID:16375792

    2015-12-01

    Migration of human population possesses a great threat to human development and nation building. A significant cause for migration is due to change in climatic conditions and vulnerabilities associated with it. Our case study focuses on the consequent reason and impact of such migration in the coastal areas of West Bengal, India. The changes in rainfall pattern and the variation of temperature have been considered as parameters which have resulted in migration. It is worthy to note that the agricultural pattern has subsequently changed over the last two decades due to change in rainfall and temperature. India being an agriculture oriented economy, the changes in the meteorological variables have not only altered the rate of agricultural pattern but also the rate of migration. A proposed framework depicting relationship between changes in meteorological variables and the migration pattern, and an estimate of how the migration pattern is expected to change over the next century by utilizing the downscaled values of future rainfall and temperature has been analyzed. Moreover, various public policy frameworks has also been proposed through the study for addressing the challenges of migration related to climate change. The proposed public policy framework has been streamlined along the lines of various international treaties and conventions in order to integrate the policy initiatives through universalization of law and policy research.

    The air transport policies of small states are currently at a crossroad. Policy makers in these countries are facing a difficult dilemma: either follow the general trend of liberalization and pay the high cost of the resulting restructuring or maintain the existing regulatory and ownership structures at the risk of isolation thus undermining the viability and sustainability of their air transport sector and their economies in general. This paper proposes to explore the broad issues raised by this difficult dilemma, to outline its special significance in the context of small states and to delineate the options opened to the economic policymakers; in these states. After a brief note on the method of research, we sketch the main elements of the international air transport industry in which the airlines of small states are called upon to act. We then propose to review the main features of the analytical framework of this debate as it pertains to the special circumstances of these states. Then we focus on the challenges facing the airlines of Small States, while the next section proposes a number of the alternative policy options open to the policy makers in these states. The main conclusions are drawn in the final section.

    Asia and the Pacific are undergoing a remarkable economic transformation which is occurring at an exceptional pace. There is clear evidence of an equally rapid epidemiological transition in the region. This paper sets out the policy challenges of building healthy societies in the context of rapid economic change. The region’s location at the crossroads of contemporary globalization, resulting in intensified population mobility, large-scale trade and investment, and pressures to take collective action on shared problems, adds to the complexity of this task. The paper argues that health is integral to building stable and sustainable societies, and that there are opportunities to develop more holistic approaches that bring together hitherto separate policy spheres.

    There are close to 15 million Asian Americans living in the United States, and they represent the fastest growing populations in the country. By the year 2050, there will be an estimated 33.4 million Asian Americans living in the country. However, their health needs remain poorly understood and there is a critical lack of data disaggregated by Asian American ethnic subgroups, primary language, and geography. This paper examines methodological issues, challenges, and potential solutions to addressing the collection, analysis, and reporting of disaggregated (or, granular) data on Asian Americans. The article explores emerging efforts to increase granular data through the use of innovative study design and analysis techniques. Concerted efforts to implement these techniques will be critical to the future development of sound research, health programs, and policy efforts targeting this and other minority populations.

    Genetic algorithms (GAs) have been used to find efficient solutions to numerous fundamental and applied problems. While GAs are a robust and flexible approach to solve complex problems, there are some situations under which they perform poorly. Here, we introduce a genetic algorithm approach that is able to solve complex tasks plagued by so-called ''golf-course''-like fitness landscapes. Our approach, which we denote variable environment genetic algorithms (VEGAs), is able to find highly efficient solutions by inducing environmental changes that require more complex solutions and thus creating an evolutionary drive. Using the density classification task, a paradigmatic computer science problem, as a case study, we show that more complex rules that preserve information about the solution to simpler tasks can adapt to more challenging environments. Interestingly, we find that conservative strategies, which have a bias toward the current state, evolve naturally as a highly efficient solution to the density classification task under noisy conditions.

Using the density classification task, a paradigmatic computer science problem, as a case study, we show that more complex rules that preserve information about the solution to simpler tasks can adapt to more challenging environments. Interestingly, we find that conservative strategies, which have a bias toward the current state, evolve naturally as a highly efficient solution to the density classification task under noisy conditions.

    This paper reexamines policies and outcomes concerning the NY Bight Restoration Plan, and the NY-NJ Harbor Estuary Program (NYNJHEP) precipitated by washups of marine debris and medical wastes in the New York Bight some 25-years ago. Findings indicate progress has been made but further work is necessary. Extensive beach closures have not occurred since 1987-88, although localized closings occur annually from pathogens. Objectives of "0" beach closures may not be feasible for some beaches, not to exceed 5% closures may be more achievable. Pathogen and DO data show further reductions of the last 10-20% will be more challenging and costly, suggesting "hot spots" be a focus for further remediation. Marine debris show increasing trends on beaches; presence of balloons, plastic bags, syringes and personal hygiene items found annually is another concern. Future challenges are on two fronts, upstream (harbor estuary based)-toxics, nutrient/organic loads, and atmospheric (bight based)-toxics, metals. PMID:25500197

    Where do poor people in the United States (US) go when they get sick? Often, they go to Federally Qualified Health Centers (FQHCs) and hospital emergency departments. Even after the implementation of the Patient Protection and Affordable Care Act (ACA), these safety-net health care organizations will continue to play a crucial role in the US health care system. FQHCs have long grappled with some of the biggest questions facing the US health care system and their leaders and clinicians face ethical challenges in everyday practice. Ethical and policy challenges in the US health care safety-net are not usually 'tragic choices' involving the allocation of transplantable organs, or ventilators during a pandemic. They are everyday choices with a tragic dimension because, even with the adoption of the ACA, the US has not yet decided whether poor people deserve a 'home' or a 'net' when they are sick, and whether even a net should be in good repair.

    2013-01-01

    Congenital heart disease (CHD) affects 1% of infants worldwide, and approximately 90% of children with serious CHD who have access to surgery survive to adulthood. Particularly as this population ages, there are unique ethical and policy challenges pertaining to this diverse population of children and adults, which also serve as a paradigm for other chronic diseases. A unique forum to discuss these issues occurred at the University of Pennsylvania in Philadelphia on March 16 to 17, 2012, and was entitled "Ethics of the Heart: Ethical and Policy Challenges in Adult and Pediatric Congenital Heart Disease." The conference convened a multidisciplinary panel of nationally known experts in the fields of Pediatric Congenital Heart Disease, Adult Congenital Heart Disease, and Bioethics to identify and discuss the most important ethical issues in CHD through talks, panel discussions, and one-on-one interviews in six topic areas: genetic testing, transitions of care from pediatric to adult CHD, transplantation and mechanical circulatory support, research and development in CHD, the social and personal costs of success in treating CHD, and end-of-life considerations. This article is an introduction to the topics discussed. PMID:23799747

    Our current information society, populated by increasingly well-informed and critical stakeholders, presents a challenge to both the policy and science arenas. The introduction of the UN Sustainable Development Goals (SDGs) offers a unique and welcome opportunity to direct joint activities towards these goals. Soil science, even though it is not mentioned as such, plays an important role in realizing a number of SDGs focusing on food, water, climate, health, biodiversity, and sustainable land use. A plea is made for a systems approach to land use studies, to be initiated by soil scientists, in which these land-related SDGs are considered in an integrated manner. To connect with policy makers and stakeholders, two approaches are functional. The first of these is the policy cycle when planning and executing research, which includes signaling, design, decision making, implementation, and evaluation. Many current research projects spend little time on signaling, which may lead to disengagement of stakeholders. Also, implementation is often seen as the responsibility of others, while it is crucial to demonstrate - if successful - the relevance of soil science. The second approach is the DPSIR approach when following the policy cycle in land-related research, distinguishing external drivers, pressures, impact, and responses to land use change that affect the state of the land in the past, present, and future. Soil science cannot by itself realize SDGs, and interdisciplinary studies on ecosystem services (ESs) provide an appropriate channel to define contributions of soil science in terms of the seven soil functions. ESs, in turn, can contribute to addressing the six SDGs (2, 3, 6, 12, 13, and 15) with an environmental, land-related character. SDGs have a societal focus and future soil science research can only be successful if stakeholders are part of the research effort in transdisciplinary projects, based on the principle of time-consuming "joint learning".

    Arid areas call for imaginative water management solutions to avoid the dangers of water shortages. Growing demands of water for domestic and industrial uses decrease the availability of water for agriculture. It therefore becomes necessary to set up a policy for the use of domestic effluents. For the province of Mendoza, Argentina, with 1,500,000 inhabitants, a master plan was designed as of 1991 for the treatment of domestic effluents and subsequent disposal for irrigation. The guidelines set up by WHO for the use of wastewater in agricultural applications were taken into consideration. At present, the Province of Mendoza has available projects which are either complete, in execution or in the bidding process, entailing secondary treatment capacity with reuse of 320,000 cubic metres/day and an estimated possible irrigation area of 10,000 hectares. With this infrastructure, some strategic lines of action are recommended to establish a policy for the agricultural use of wastewater: (a) to program the use of treated wastewater to avoid discharges to irrigation flows; (b) to develop an institutional scheme for the efficient and safe use of these waters; and (c) develop scientific and technologic know-how to accompany the updated policies.

    The "Grand Challenges" to address Global Change identified by the International Council for Science (ICSU) and its partners through the Earth System Sustainability Initiative-improving forecasting, enhancing and integrating observation systems, confining and minimizing global environmental change, responding effectively to change, as well as innovating and evaluating these efforts-require an integrative approach that engages and inspires society in general and young people in particular. What are some of the effective strategies-and stumbling blocks-in being able to make Earth System science and related sustainability efforts relevant and practical to non-technical audiences? Recent climate education projects have pioneered new strategies toward linking and infusing research with education, science with solutions. For example, the Climate Literacy and Energy Awareness Network (CLEAN), a National Science Digital Library Pathway funded by NSF, has approached this integral approach by "closing the loop" between climate and energy topics, identifying and annotating high quality online resources relating to the carbon cycle and related topics. The Inspiring Climate Education Excellence (ICEE) project, funded by NASA, offers professional development for teachers that infuses climate science with solutions as an emerging "best practice" while being sensitive to the emotional, psychological and political aspects of avoiding "gloom and doom" on one hand or advocating for particular policy solutions on another. Other examples includes NASA's climate website (http://climate.nasa.gov ), which serves as a robust, engaging portal for climate research and data, especially for educators. The recent PBS series Earth: The Operators' Manual and related book and website are other recent example of how climate science research, education and solutions can be incorporated in a way that is appealing and informative.

    This paper investigates the F-policy queue using fuzzy parameters, in which the arrival rate, service rate, and start-up rate are all fuzzy numbers. The F-policy deals with the control of arrivals in a queueing system, in which the server requires a start-up time before allowing customers to enter. A crisp F-policy queueing system generalised to a fuzzy environment would be widely applicable; therefore, we apply the α-cuts approach and Zadeh's extension principle to transform fuzzy F-policy queues into a family of crisp F-policy queues. This study presents a mathematical programming approach applicable to the construction of membership functions for the expected number of customers in the system. Furthermore, we propose an efficient solution procedure to compute the membership function of the expected number of customers in the system under different levels of α. Finally, we give an example of the proposed system as applied to a case in the automotive industry to demonstrate its practicality.

    Preoperative psychosocial assessment is the standard of care for patients seeking weight-loss surgery (WLS). However, the assessment procedure varies widely by surgery site. Comprehensive assessments can provide a wealth of information that assists both the patient and the treatment team, anticipate and prepare for challenges associated with extensive behavioral and lifestyle changes that are required postsurgery. In this review, we provide an overview of the purpose of the preoperative psychosocial assessment and domains to be included. Challenges commonly identified in the assessment are discussed, including maladaptive eating behaviors, psychiatric comorbidities, and alcohol use. Potential solutions and approaches to these challenges are provided. Additionally, patient populations requiring special consideration are presented to include adolescents, those with cognitive vulnerabilities, and aging adults. PMID:26604844

    Northern California's Mendocino County is joining the national movement to upgrade the quantity and quality of local data available for assessing and improving local health. A broad-based coalition in the county has successfully engaged 20 community partners in funding a web-based tool for this purpose. HealthyMendocino.org, launched in January 2013, is designed to support setting local priorities, planning and evaluating the program, and building community by giving easy access to timely data on 90 indicators of local health and its determinants compiled from a range of state and federal sources. This article, written before the site's launch by the Chair of the Healthy Mendocino Steering Committee, describes the community of solution that came together to envision, publicize, raise support for, and bring to fruition this new resource. Mendocino is a rural county with limited financial capacity but rich social assets, including a strong collaborative tradition and an infrastructure of dynamic coalitions. This article outlines the anticipated benefits, early lessons, and challenges of the initiative and explains how the organizers leveraged connections with other communities of solution that already are working to improve the quality of life in the area. The article also notes ways in which this local initiative illustrates and aligns with several of the grand challenges outlined in the modern Folsom Report-specifically, challenges 7, 8, 11, 12, and above all 13, which concerns the use of health information technology to enable the flow of knowledge to the community of solution.

    Background Following the adoption of the Millennium Development Goal 4 (MDG 4) in Ghana to reduce under-five mortality by two-thirds between 1990 and 2015, efforts were made towards its attainment. However, impacts and challenges of implemented intervention programs have not been examined to inform implementation of Sustainable Development Goal 3.2 (SDG 3.2) that seeks to end preventable deaths of newborns and children aged under-five. Thus, this study aimed to compare trends in neonatal, infant, and under-five mortality over two decades and to highlight the impacts and challenges of health policies and intervention programs implemented. Design Ghana Demographic and Health Survey data (1988–2008) were analyzed using trend analysis. Poisson regression analysis was applied to quantify the incidence rate ratio of the trends. Implemented health policies and intervention programs to reduce childhood mortality in Ghana were reviewed to identify their impact and challenges. Results Since 1988, the annual average rate of decline in neonatal, infant, and under-five mortality in Ghana was 0.6, 1.0, and 1.2%, respectively. From 1988 to 1989, neonatal, infant, and under-five mortality declined from 48 to 33 per 1,000, 72 to 58 per 1,000, and 108 to 83 per 1,000, respectively, whereas from 1989 to 2008, neonatal mortality increased by 2 per 1,000 while infant and under-five mortality further declined by 6 per 1,000 and 17 per 1,000, respectively. However, the observed declines were not statistically significant except for under-five mortality; thus, the proportion of infant and under-five mortality attributed to neonatal death has increased. Most intervention programs implemented to address childhood mortality seem not to have been implemented comprehensively. Conclusion Progress towards attaining MDG 4 in Ghana was below the targeted rate, particularly for neonatal mortality as most health policies and programs targeted infant and under-five mortality.

    2014-01-01

    Background and Objectives: After the widespread application of minimally invasive surgery for benign diseases and given its proven safety and efficacy, minimally invasive surgery for gastrointestinal cancer has gained substantial attention in the past several years. Despite the large number of publications on the topic and level I evidence to support its use in colon cancer, minimally invasive surgery for most gastrointestinal malignancies is still underused. Methods: We explore some of the challenges that face the fusion of minimally invasive surgery technology in the management of gastrointestinal malignancies and propose solutions that may help increase the utilization in the future. These solutions are based on extensive literature review, observation of current trends and practices in this field, and discussion made with experts in the field. Results: We propose 4 different solutions to increase the use of minimally invasive surgery in the treatment of gastrointestinal malignancies: collaboration between surgical oncologists/hepatopancreatobiliary surgeons and minimally invasive surgeons at the same institution; a single surgeon performing 2 fellowships in surgical oncology/hepatopancreatobiliary surgery and minimally invasive surgery; establishing centers of excellence in minimally invasive gastrointestinal cancer management; and finally, using robotic technology to help with complex laparoscopic skills. Conclusions: Multiple studies have confirmed the utility of minimally invasive surgery techniques in dealing with patients with gastrointestinal malignancies. However, training continues to be the most important challenge that faces the use of minimally invasive surgery in the management of gastrointestinal malignancy; implementation of our proposed solutions may help increase the rate of adoption in the future.

    China is confronted with the dual task of developing its national economy and protecting its ecological environment. Since the 1980s, China's policies on environmental protection and sustainable development have experienced five changes: (1) progression from the adoption of environmental protection as a basic state policy to the adoption of sustainable development strategy; (2) changing focus from pollution control to ecological conservation equally; (3) shifting from end-of-pipe treatment to source control; (4) moving from point source treatment to regional environmental governance; and (5) a turn away from administrative management-based approaches and towards a legal means and economic instruments-based approach. Since 1992, China has set down sustainable development as a basic national strategy. However, environmental pollution and ecological degradation in China have continued to be serious problems and have inflicted great damage on the economy and quality of life. The beginning of the 21st century is a critical juncture for China's efforts towards sustaining rapid economic development, intensifying environmental protection efforts, and curbing ecological degradation. As the largest developing country, China's policies on environmental protection and sustainable development will be of primary importance not only for China, but also the world. Realizing a completely well-off society by the year 2020 is seen as a crucial task by the Chinese government and an important goal for China's economic development in the new century, however, attaining it would require a four-fold increase over China's year 2000 GDP. Therefore, speeding up economic development is a major mission during the next two decades and doing so will bring great challenges in controlling depletion of natural resources and environmental pollution. By taking a critical look at the development of Chinese environmental policy, we try to determine how best to coordinate the relationship between the

    Reproductive tourism, or "cross-border reproductive care", is the phenomenon of people crossing international borders to access reproductive technologies. One of the fastest-growing categories of cross-border reproductive care is international surrogacy, the act of infertile clients traveling internationally to engage the paid services of foreign surrogates to carry their babies to term. It is a multibillion-dollar global industry presenting unique legal, ethical, and risk-management challenges. Clients tend to be price-sensitive, middle-income individuals seeking services from surrogates who in the global market are thought to be of quite low socioeconomic status. Risks are experienced by all parties involved in the transaction, including the client's countries of origin and destination. The risks to the surrogate evolve from the potential to exploit her economic vulnerability in order to encourage both consent and unfair pricing. Opportunities for policy development are explored.

    Professionals should reexamine negative assumptions about the quality of life with prenatally detectable impairments and should reform clinical practice and public policy to improve informed decision making and genuine reproductive choice. Current data on children and families affected by disabilities indicate that disability does not preclude a satisfying life. Many problems attributed to the existence of a disability actually stem from inadequate social arrangements that public health professionals should work to change. This article assumes a pro-choice perspective but suggests that unreflective uses of prenatal testing could diminish, rather than expand, women's choices. This critique challenges the view of disability that lies behind the social endorsement of such testing and the conviction that women will or should end their pregnancies if they discover that the fetus has a disabling trait.

    Issues relating to confidentiality and consent for physical and mental health treatment with minor clients can pose challenges health care providers. Decisions need to be made regarding these issues despite the absence of clear, direct, or comprehensive policies and legislation. In order to fully understand the scope of this topic, a systemic review of several pieces of legislation and guidelines related to this topic are examined. These include the: Canadian Human Rights Act, Children's Rights: International and National Laws and Practices, Health Information Act, Gillick Competence and Medical Emancipation, Freedom of Information and Protection of Privacy Act, Child, Youth and Family Enhancement Act, Common Law Mature Minor Doctrine, and Alberta Health Services Consent to Treatment/Practice(s) Minor/Mature Minor.

  18. Challenges and Solutions in Implementing Hydrological Models within Scientific Workflow Software

    NASA Astrophysics Data System (ADS)

    Perraud, J.; Fitch, P. G.; Bai, Q.

    2010-12-01

    The use of scientific workflow software in the hydrology domain appears to have gained traction in the past few years, to better handle data streams, pipelines of processing steps, QA/QC, metadata and provenance. The Hydrologists’ Workbench (HWB) is a software toolset building on the Trident scientific workflow software (http://tridentworkflow.codeplex.com/), adding data handling and processing activities that are primarily aimed at the hydrology domain. One important source of processing activities is found in several existing environmental modelling software systems. Making these components available through HWB brings several challenges. While many environmental modelling systems have conceptually similar characteristics at a high level, their implementation will naturally vary in many respects, bringing to HWB the traditional challenge of model and data interoperability between heterogeneous systems. The challenges fall arguably into two broad categories: data interoperability and model of execution. The former stems from wanting to seamlessly pass data between processing activities that may have very different back-end implementations. The latter arises with the possible incompatibilities, conceptual or technical, between the workflow execution engine and the way a model or modelling component needs to be executed. We illustrate these challenges and propose some solutions by reporting the findings of a case study incorporating a spatial-temporal surface runoff modelling toolset in HWB. We find notably two salient challenges, the definition of an appropriate granularity for the workflow activities wrapping the existing modelling components, and the need for a common, implementation-neutral scientific data model.

    2016-05-28

    Since 1945, the provision of health care in France has been grounded in a social conception promoting universalism and equality. The French health-care system is based on compulsory social insurance funded by social contributions, co-administered by workers' and employers' organisations under State control and driven by highly redistributive financial transfers. This system is described frequently as the French model. In this paper, the first in The Lancet's Series on France, we challenge conventional wisdom about health care in France. First, we focus on policy and institutional transformations that have affected deeply the governance of health care over past decades. We argue that the health system rests on a diversity of institutions, policy mechanisms, and health actors, while its governance has been marked by the reinforcement of national regulation under the aegis of the State. Second, we suggest the redistributive mechanisms of the health insurance system are impeded by social inequalities in health, which remain major hindrances to achieving objectives of justice and solidarity associated with the conception of health care in France.

    It is estimated that in 2000 almost 175 million people, or 2.9% of the world's population, were living outside their country of birth, compared to 100 million, or 1.8% of the total population, in 1995. As the global labour market strengthens, it is increasingly highly skilled professionals who are migrating. Medical practitioners and nurses represent a small proportion of highly skilled workers who migrate, but the loss of health human resources for developing countries can mean that the capacity of the health system to deliver health care equitably is compromised. However, data to support claims on both the extent and the impact of migration in developing countries is patchy and often anecdotal, based on limited databases with highly inconsistent categories of education and skills.The aim of this paper is to examine some key issues related to the international migration of health workers in order to better understand its impact and to find entry points to developing policy options with which migration can be managed.The paper is divided into six sections. In the first, the different types of migration are reviewed. Some global trends are depicted in the second section. Scarcity of data on health worker migration is one major challenge and this is addressed in section three, which reviews and discusses different data sources.

  3. Considering the cumulative risk of mixtures of chemicals – A challenge for policy makers

    PubMed Central

    2012-01-01

    Background The current paradigm for the assessment of the health risk of chemical substances focuses primarily on the effects of individual substances for determining the doses of toxicological concern in order to inform appropriately the regulatory process. These policy instruments place varying requirements on health and safety data of chemicals in the environment. REACH focuses on safety of individual substances; yet all the other facets of public health policy that relate to chemical stressors put emphasis on the effects of combined exposure to mixtures of chemical and physical agents. This emphasis brings about methodological problems linked to the complexity of the respective exposure pathways; the effect (more complex than simple additivity) of mixtures (the so-called 'cocktail effect'); dose extrapolation, i.e. the extrapolation of the validity of dose-response data to dose ranges that extend beyond the levels used for the derivation of the original dose-response relationship; the integrated use of toxicity data across species (including human clinical, epidemiological and biomonitoring data); and variation in inter-individual susceptibility associated with both genetic and environmental factors. Methods In this paper we give an overview of the main methodologies available today to estimate the human health risk of environmental chemical mixtures, ranging from dose addition to independent action, and from ignoring interactions among the mixture constituents to modelling their biological fate taking into account the biochemical interactions affecting both internal exposure and the toxic potency of the mixture. Results We discuss their applicability, possible options available to policy makers and the difficulties and potential pitfalls in implementing these methodologies in the frame of the currently existing policy framework in the European Union. Finally, we suggest a pragmatic solution for policy/regulatory action that would facilitate the evaluation of

    The ongoing Ebola epidemic in West Africa has drawn attention to global health inequalities, in particular the inadequacies of health care systems in sub-Saharan African countries for appropriately managing and containing infectious diseases. The purpose of this article is to examine the sociopolitical and economic conditions that created the environment for the Ebola epidemic to occur, identify challenges to and opportunities for the prevention and control of Ebola and future outbreaks, and discuss policy recommendations and priority areas for addressing the Ebola epidemic and future outbreaks in West Africa. Articles in peer-reviewed journals on health system reforms in developing countries and periodicals of international organizations were used to gather the overview reported in this article. We identify individual, structural, and community challenges that must be addressed in an effort to reduce the spread of Ebola in West Africa. The Ebola epidemic in West Africa underscores the need for the overhaul and transformation of African health care systems to build the capacity in these countries to address infectious diseases. Public-private partnerships for investment in developing countries' health care systems that involve the international community are critical in addressing the current Ebola epidemic and future outbreaks.

    In Thailand, the prevalence of smoking has steadily declined over the past 20 years, suggesting an effective tobacco control policy. However, the prevalence has recently stabilised and youth smoking now appears to be on the rise. Tobacco use is the third highest risk factor contributing to the burden of disease in the country. This is an issue of concern and led to the present review of tobacco control measures in Thailand. The present evidence-based review shows that Thailand's tobacco control measures are relatively strong and comply well with the WHO Framework Convention on Tobacco Control in terms of taxation, advertisement through popular media, and warning labels on cigarettes and other tobacco product packages. However, challenges remain in dealing with highly prevalent roll-your-own cigarettes, strict prohibition of tobacco sale to underage youths, household smoking, illicit trade of tobacco products, viable tobacco crop diversification for domestic tobacco growers and liability. If these challenges are met, the prevalence of tobacco consumption could possibly be further reduced. PMID:21791510

    It is a challenge to researchers to present their results in a way that serves the needs of health policy makers. Small area maps of life expectancy provide an insightful presentation. In this study, we pursued small area comparisons on a scale that is smaller than is currently available on a province-wide basis. We visualized Nova Scotia's provincial variation in health and identified the Cape Breton Regional Municipality and Halifax's disadvantaged "North End" neighbourhood as areas with major health concerns. The observed health differences are only partially explained by socioeconomic factors such as income and unemployment. The study also demonstrated the feasibility of small area comparisons at the level of census consolidated subdivisions and neighbourhoods. There are various methodological challenges for researchers, however: allocation procedures such as the postal code-conversion-file may introduce substantial error; the application of appropriate spatial smoothing procedures is crucial to the interpretation of regional variation in health; and the migration of frail individuals to nursing homes affects the geographic variation in health.

    The original focus on energy and protein needs for combating malnutrition gave way to UNICEF promoted concerns for maternal care and complementary feeding in association with longer-term breast feeding. Nevertheless the World Food Summit's drive to halve malnutrition rates by 2015 was not accelerating the fall in malnutrition prevalences. The UN's Standing Committee on Nutrition's commission highlighted the crucial role of maternal nutrition and low birthweights, the need for a life cycle approach to prevention and the current global effects of maternal/fetal and childhood malnutrition in amplifying the impact of the new epidemic of obesity and chronic diseases. The emphasis on poverty reduction and free market solutions is too crude and national interventions geared to protecting the vulnerable, promoting equity with major community involvement in integrated multifaceted programmes are needed. The same principles apply to overnutrition and specifically to the avoidance of the current pandemic of the metabolic syndrome. An intergenerational amplification of diabesity is now emerging as overweight but poorly fed micronutrient deficient girls enter pregnancy and produce ever more susceptible children. So new strategies are now needed as recognized by economists but not by doctors and nutritionists! Economy, agriculture, food processing and marketing policy changes are crucial in determining patterns of food consumption because the costs of foods and their availability, rather than policies centred on individual responsibility for consumer choice, are the keys to making coherent public health advances.

    Water-related risks threaten society at the local, national and global scales in our inter-connected and rapidly changing world. Most of the world's poor are deeply water insecure and face intolerable water-related risks associated with complex hydrology. Most of the world's wealthy face lower water-related risks and less complex hydrology. This inverse relationship between hydrological complexity and wealth contributes to a divided world. This must be addressed if global water security is to be achieved. Using a risk-based framework provides the potential to link the current policy-oriented discourse on water security to a new and rigorous science-based approach to the description, measurement, analysis and management of water security. To provide the basis for this science-based approach, we propose an encompassing definition rooted in risk science: water security is a tolerable level of water-related risk to society. Water security policy questions need to be framed so that science can marshal interdisciplinary data and evidence to identify solutions. We join a growing group of scientists in asserting a bold vision for science leadership, calling for a new and comprehensive understanding of the planet's water system and society's water needs.

    Background: around the world health systems constantly face increasing pressures which arise from many factors, such as an ageing population, patients and providers demands for equipment’s and services. In order to respond these challenges and reduction of health system’s transactional costs, referral solutions are considered as a key factor. This study was carried out to identify referral solutions that have had successes. Methods: relevant studies identified using keywords of referrals, consultation, referral system, referral model, referral project, electronic referral, electronic booking, health system, healthcare, health service and medical care. These searches were conducted using PubMed, ProQuest, Google Scholar, Scopus, Emerald, Web of Knowledge, Springer, Science direct, Mosby’s index, SID, Medlib and Iran Doc data bases. 4306 initial articles were obtained and refined step by step. Finally, 27 articles met the inclusion criteria. Results: we identified seventeen e-referral systems developed in UK, Norway, Finland, Netherlands, Denmark, Scotland, New Zealand, Canada, Australia, and U.S. Implemented solutions had variant degrees of successes such as improved access to specialist care, reduced wait times, timeliness and quality of referral communication, accurate health information transfer and integration of health centers and services. Conclusion: each one of referral solutions has both positive and changeable aspects that should be addressed according to sociotechnical conditions. These solutions are mainly formed in a small and localized manner. PMID:26236167

    2011-01-01

    Introduction Achieving health equity is a pertinent need of the developing health systems. Though policy process is crucial for planning and attaining health equity, the existing evidences on policy processes are scanty in this regard. This article explores the magnitude, determinants, challenges and prospects of 'health equity approach' in various health policy processes in the Indian State of Orissa - a setting comparable with many other developing health systems. Methods A case-study involving 'Walt-Gilson Policy Triangle' employed key-informant interviews and documentary reviews. Key informants (n = 34) were selected from the departments of Health and Family Welfare, Rural Development, and Women and Child Welfare, and civil societies. The documentary reviews involved various published and unpublished reports, policy pronouncements and articles on health equity in Orissa and similar settings. Results The 'health policy agenda' of Orissa was centered on 'health equity' envisaging affordable and equitable healthcare to all, integrated with public health interventions. However, the subsequent stages of policy process such as 'development, implementation and evaluation' experienced leakage in the equity approach. The impediment for a comprehensive approach towards health equity was the nexus among the national and state health priorities; role, agenda and capacity of actors involved; and existing constraints of the healthcare delivery system. Conclusion The health equity approach of policy processes was incomprehensive, often inadequately coordinated, and largely ignored the right blend of socio-medical determinants. A multi-sectoral, unified and integrated approach is required with technical, financial and managerial resources from different actors for a comprehensive 'health equity approach'. If carefully geared, the ongoing health sector reforms centered on sector-wide approaches, decentralization, communitization and involvement of non-state actors can

    The urgent need in Africa for research capacity building has been recognized by African leaders and governments for many years. However, lack of large research funding opportunities has been seen as a major obstacle to improving research capacity in precisely those countries that need it the most. Microfinance has shown that a small infusion of capital can "prime the pump" to creative local economic productivity. In a similar way, MicroResearch has proven effective in promoting a similar bottom-up strategy to find sustainable solutions to local health challenges through local community focused research. Specifically, MicroResearch through hands-on didactic courses, mentoring and small-scale research funding promotes small research projects that improve research skills across the entire health-care provider spectrum to unleash a culture of inquiry. This in turn stimulates health care providers to identify the locally most relevant obstacles that need to be overcome and implement locally feasible and sustainable solutions. MicroResearch is a bottom-up strategy proven effective at finding sustainable solutions to local health challenges. PMID:25934328

  13. The European Water Framework Directive: Challenges For A New Type of Social and Policy Analysis

    NASA Astrophysics Data System (ADS)

    Pahl-Wostl, C.

    Water resources managment is facing increasing uncertainties in all areas. Socio- economic boundary conditions change quickly and require more flexible management strategies. Climate change, for example results in an increase in uncertainties, in par- ticular extreme events. Given the fact that current management practices deal with extreme events by designing the technical systems to manage the most extreme of all cases (e.g. higher dams for the protection against extreme floods, larger water reser- voirs for droughts and to meet daily peak demand) a serious problem is posed for long-term planning and risk management. Engineering planning has perceived the hu- man dimension as exogenous boundary conditions. Legislation focused largely on the environmental and technological dimensions that set limits and prescribe new tech- nologies without taking the importance of institutional change into account. However, technology is only the "hardware" and it is becoming increasingly obvious that the "software", the social dimension, has to become part of planning and management processes. Hence, the inclusion of the human dimension into integrated models and processes will be valuable in supporting the introduction of new elements into plan- ning processes in water resources management. With the European Water Framework Directive environmental policy enters a new era. The traditional approach to solving isolated environmental problems with technological fixes and end-of-pipe solutions has started to shift towards a more thoughtful attitude which involves the development of integrated approaches to problem solving. The WFD introduces the river basin as the management unit, thus following the experience of some European countries (e.g. France) and the example of the management of some international rivers (e.g. the Rhine). Overall the WFD represents a general shift towards a polycentric understand- ing of policy making that requires the involvement of stakeholders as active

The increasing use of this term is closely related to the astonishing advancement in DNA sequencing technologies and other high-throughput biotechnologies. A large amount of personal genomic data can be generated by these technologies in a short time. Consequently, the needs for managing, analyzing, and interpreting these personal genomic data to facilitate personalized care are escalated. In this article, we discuss the challenges for implementing genomics-based personalized medicine in healthcare, current solutions to these challenges, and the roles of health information management (HIM) professionals in genomics-based personalized medicine.

    Radar is becoming an important tool used to gather data on bird and bat activity at proposed and existing land-based wind energy sites. Radar will likely play an even more important role at the increasing development of wind energy offshore, given both the lack of knowledge about bird and bat activity offshore and the increased difficulty in obtaining offshore information. Most radar studies to date have used off-the-shelf or modified marine radars. However, there are several issues that continue to hinder the potential usefulness of radar at wind energy sites, with offshore sites providing a particular suite of challenges. We identify these challenges along with current or developing solutions. PMID:19828157

    The European Spallation Source (ESS), Lund, Sweden will be a 5MW long-pulse neutron spallation research facility and will enable new opportunities for researchers in the fields of life sciences, energy, environmental technology, cultural heritage and fundamental physics. Neutrons are produced by accelerating a high-energy proton beam into a rotating helium-cooled tungsten target. These neutrons pass through moderators to reduce their energy to an appropriate range (< 5 meV for cold neutrons); two of which will use liquid hydrogen at 17 K as the moderating and cooling medium. There are several technical challenges to overcome in the design of a robust system that will operate under such conditions, not least the 20 kW of deposited heat. These challenges and the associated design solutions will be detailed in this paper.

    We face the challenge of providing adequate medical attention to a growing and aging population. Even societies with the best healthcare standards are not prepared to provide adequate medical attention to a growing population. Globally, these problems are magnified as medical care is a mélange ranging from obsolete techniques to state-of-the-art care. A solution to providing proper healthcare in every society, and closing the gap between developed and underserved communities, is the implementation of wireless based preventive medicine. The key components to universalize wireless health care are device miniaturization, increased shelf-life of bio-reagents, and low production cost of medical devices.

    Osmotically driven membrane processes (ODMP) have gained renewed interest in recent years and they might become a potential solution for the world's most challenging problems of water and energy scarcity. Though the concept of utilizing osmotic pressure difference between high and low salinity streams across semipermeable membranes has been explored for several decades, lack of optimal membranes and draw solutions hindered competition between forward osmosis (FO) and pressure retarded osmosis (PRO) with existing water purification and power generation technologies, respectively. Driven by growing global water scarcity and by energy cost and negative environmental impacts, novel membranes and draw solutions are being developed for ODMPs, mass and heat transfer in osmotic process are becoming better understood, and new applications of ODMPs are emerging. Therefore, OMDPs might become promising green technologies to provide clean water and clean energy from abundantly available renewable resources. This review focuses primarily on new insights into osmotic membrane transport mechanisms and on novel membranes and draw solutions that are currently being developed. Furthermore, the effects of operating conditions on the overall performance of osmotic membranes will be highlighted and future perspectives will be presented. PMID:23778699

    2014-06-01

    Purpose: Develop solutions to critical medical physics challenges in Tanzania. Methods: In September of 2013 we began working with Jumaa Bin Dachi, a Therapy Physicist at the Ocean Road Cancer Institute in Dar es Salaam, Tanzania. We developed a bi-lateral learning partnership over the course of eight qualitative Skype meetings with Jumaa. From these meetings we have ascertained that there is a gap between the installation of new equipment and treating patients. This gap has often been overlooked by international partners attempting to improve radiation therapy access. Relationships with academic institutions abroad can fill these gaps, and lead to sustained care of patients needing radiation. Results: Our efforts are best given in a supporting role to help develop solutions and new technology that can reduce the burden on the Medical Physicist. Solutions may include: training material, support for radiation therapy classes, development of appropriate local protocols, and peer-review on documents being produced. New technology needs to focus around simple and easy field shaping, improved patient imaging systems, and systems for patient set-up. We believe our work can help alleviate some of the burdens faced by this institute. Conclusion: While we are just in the beginning stage of this partnership, we believe there is great potential for success between both parties. We hope that the Ocean Road Cancer Institute will benefit from potential funding and resources by partnering with a High Income Country to develop affordable solutions to clinical problems in Tanzania.

    With more than 60% of the land farmed, with vulnerable freshwater and marine environments, and with one of the most intensive, export-oriented livestock sectors in the world, the nitrogen (N) pollution pressure from Danish agriculture is severe. Consequently, a series of policy action plans have been implemented since the mid 1980s with significant effects on the surplus, efficiency and environmental loadings of N. This paper reviews the policies and actions taken and their ability to mitigate effects of reactive N (Nr) while maintaining agricultural production. In summary, the average N-surplus has been reduced from approximately 170 kg N ha-1 yr-1 to below 100 kg N ha-1 yr-1 during the past 30 yrs, while the overall N-efficiency for the agricultural sector (crop + livestock farming) has increased from around 20-30% to 40-45%, the N-leaching from the field root zone has been halved, and N losses to the aquatic and atmospheric environment have been significantly reduced. This has been achieved through a combination of approaches and measures (ranging from command and control legislation, over market-based regulation and governmental expenditure to information and voluntary action), with specific measures addressing the whole N cascade, in order to improve the quality of ground- and surface waters, and to reduce the deposition to terrestrial natural ecosystems. However, there is still a major challenge in complying with the EU Water Framework and Habitats Directives, calling for new approaches, measures and technologies to mitigate agricultural N losses and control N flows.

    SummaryWe consider the implementation of Australian water reform over the last two decades and into the future. Reform was to provide security for consumptive users and adequate rights for the environment. Overallocation, a key threat to both these aims, continues to challenge planners particularly in the Murray-Darling Basin and cannot be addressed without community support. We draw from four major studies to provide insights on how implementation needs to be underpinned by theory. From the perspective of institutional design for collaborative and sustainable water planning, seven major improvements are required: (1) Provision of detailed policy guidelines to support general legal requirements, particularly practical advice for interpreting and applying the precautionary principle. (2) Tools to identify and engage unorganised or neglected community sectors, for example Indigenous peoples and youth. (3) Procedural fairness and transparent decision making, to build confidence in reform; use of independent experts and visual tools to improve the quality of discussion and increase the acceptability of trade-offs. (4) Clearer documentation and language in planning, as more litigation is likely. (5) In accord with international literature, the development of comprehensive policy and legislative framework allowing a systems approach to consensus building, especially when the science is contested. (6) Information on exactly how much water is required and where, by capturing societal choices on environmental assets. (7) Planning for sustainable contraction where cutbacks to water use is required, as an additional strategy to the current emphasis on buying water or building infrastructure. In summary we advocate collaborative water planning processes to engender community confidence in planning.

    Migration is an increasingly significant driver of transformations in family configurations and caregiving practices as well as living arrangements. The sustainability of geographically-split family formations is dependent on several factors, including the presence and strength of care support networks among migrants and their left-behind families, access to communication infrastructure and the stability of the families’ financial resources. Drawing on both a selective review of relevant academic literature as well as key findings from the CHAMPSEA Project, the article first examines the effects of these three factors on the well-being of migrants’ left-behind family members, especially children. The article also considers major implications of the project’s findings, as well as possible challenges for migration and development policies. One area of concern for migration and development policy arising from our research findings is the need to provide better support for left-behind caregivers or carers who are substituting for the absent migrant in childcare and domestic work but who may also need care and support themselves. Another area relates to the need to improve communication infrastructure to help migrants and their families maintain their relationships across transnational spaces; while a third lies with the importance of minimizing migrant families’ economic stress stemming from the cycle of debts resulting from exorbitant broker fees and the mismanagement of remittances. By acknowledging both the social and economic costs of international labor migration on families, governments of labor-sending countries can create a more effective legal and institutional framework as well as design suitable supporting mechanisms for left-behind families. There is then a stronger possibility that migration can become a sustainable development strategy for transnational families in South-East Asia. PMID:24954965

    2009-04-01

    The pattern of chronic disease varies hugely internationally, and this is now reflected in Europe's multi-ethnic populations. This is creating challenges for epidemiology, public health and clinical care. Human rights legislation and health policies are mandating equity of service i.e. equal needs being met equally well. Indicators of race and ethnicity demonstrate important variations in health and health care, but the data are sparse, especially in Southern and Eastern Europe, and for some ethnic groups across the continent. Ethnic coding of routine health databases is required. The task will best succeed as a national one, with European level coordination and guidance on concepts. Pending this achievement, data linkage techniques can help fill the information gap. One of many ongoing debates that need resolution across Europe is on the preferred indicator of ethnicity, related terminology and mode of measurement. Original research also needs expansion, especially in relation to cohort studies and trials and boosted samples of ethnic minority groups in large scale European health surveys. Such work may require European legislation of the kind that has been effective in the United States (NIH Revitalisation Act 1993). A dialogue between policy makers, funders, researchers and practitioners is needed urgently as a precursor to engaging the public. PMID:19307249

  6. Policy challenges for the pediatric rheumatology workforce: Part II. Health care system delivery and workforce supply

    PubMed Central

    2011-01-01

    The United States pediatric population with chronic health conditions is expanding. Currently, this demographic comprises 12-18% of the American child and youth population. Affected children often receive fragmented, uncoordinated care. Overall, the American health care delivery system produces modest outcomes for this population. Poor, uninsured and minority children may be at increased risk for inferior coordination of services. Further, the United States health care delivery system is primarily organized for the diagnosis and treatment of acute conditions. For pediatric patients with chronic health conditions, the typical acute problem-oriented visit actually serves as a barrier to care. The biomedical model of patient education prevails, characterized by unilateral transfer of medical information. However, the evidence basis for improvement in disease outcomes supports the use of the chronic care model, initially proposed by Dr. Edward Wagner. Six inter-related elements distinguish the success of the chronic care model, which include self-management support and care coordination by a prepared, proactive team. United States health care lacks a coherent policy direction for the management of high cost chronic conditions, including rheumatic diseases. A fundamental restructure of United States health care delivery must urgently occur which places the patient at the center of care. For the pediatric rheumatology workforce, reimbursement policies and the actions of health plans and insurers are consistent barriers to chronic disease improvement. United States reimbursement policy and overall fragmentation of health care services pose specific challenges for widespread implementation of the chronic care model. Team-based multidisciplinary care, care coordination and self-management are integral to improve outcomes. Pediatric rheumatology demand in the United States far exceeds available workforce supply.

    Psychiatric nurses play an important role in the process of caring for mentally ill patients and are continually faced with the numerous challenges and complex issues related to this field. This study aimed to understand the perspectives of psychiatric nurses regarding the issues they face while providing care and examine the possible solutions for improvement of inpatient care in clinical settings. The study adopted a qualitative approach that utilized a content analysis of audio taped, semi-structured interviews that had been conducted with 24 nurses. Two main themes emerged from the data. The first, Challenges in Providing Care within Psychiatric Wards, had the following subthemes: Politics and Rules of Organization, Safety and Security Issues, Uncertainty about the Role, Lack of Trained Staff, and Sociocultural Issues. The second theme, Solutions for Improving Psychiatric Care, had the subthemes of Empowerment across four domains: Psychiatric Nurses, Mentally Ill Patients and their Families, The Psychiatric Mental Health System, and the Cultural Context. The results indicated that if nurses are expected to provide optimal nursing care within a psychiatric ward, then there is a need for a stable and responsible organizational structure, skilled psychiatric nurses, and community-based care along with an anti-stigma program.

    Context: Pragmatic trials lack the relatively tight quality control of traditional efficacy studies and hence may pose added analytic challenges owing to the practical realities faced in carrying them out. Case Description: STOP CRC is a cluster randomized trial testing the effectiveness of automated, electronic medical record (EMR)-driven strategies to raise colorectal cancer (CRC) screening rates in safety net clinics. Screen-eligible participants were accrued during year 1 and followed for 12 months (measurement window) to assess completion of a fecal screening test. Control clinics implemented the intervention in year 2. Implementation Challenges/Analytic Issues: Due to limitations on how we could build the intervention tools, the overlap of the year 1 measurement windows with year 2 intervention rollout posed a potential for contamination of the primary outcome for control participants. In addition, a variety of factors led to a lack of synchronization of the measurement windows with actual intervention delivery. In both cases, the net impact of these factors would be to diminish the estimated impact of the intervention. Proposed Solutions: We dealt with the overlap issue by delaying the start of intervention rollout to control clinics in year 2 by 6 months and by truncating the measurement windows for intervention and control participants at this point. In addition we formulated three sensitivity analyses to help address the issue of asynchronization. Conclusion: This case study might help other investigators facing similar challenges think about such issues and the pros and cons of various strategies for dealing with them. PMID:26793738

    Falling particle receivers (FPR) utilize small particles as a heat collecting medium within a cavity receiver structure. Previous analysis for FPR systems include computational fluid dynamics (CFD), analytical evaluations, and experiments to determine the feasibility and achievability of this CSP technology. Sandia National Laboratories has fabricated and tested a 1 MWth FPR that consists of a cavity receiver, top hopper, bottom hopper, support structure, particle elevator, flux target, and instrumentation. Design requirements and inherent challenges were addressed to enable continuous operation of flowing particles under high-flux conditions and particle temperatures over 700 °C. Challenges include being able to withstand extremely high temperatures (up to 1200°C on the walls of the cavity), maintaining particle flow and conveyance, measuring temperatures and mass flow rates, filtering out debris, protecting components from direct flux spillage, and measuring irradiance in the cavity. Each of the major components of the system is separated into design requirements, associated challenges and corresponding solutions. The intent is to provide industry and researchers with lessons learned to avoid pitfalls and technical problems encountered during the development of Sandia's prototype particle receiver system at the National Solar Thermal Test Facility (NSTTF).

    One of the first government-sponsored demands for integrated assessment to support decision making in the United States is embodied in the National Environmental Policy Act of 1969 (NEPA). Over the past 25 years, Oak Ridge National Laboratory (ORNL) has supported federal agencies` in evaluating health and environmental impacts as required by NEPA. Many of ORNL`s efforts have focused on complex, programmatic assessments that break new ground and require and integrate expertise from a wide range of technical disciplines. Examples of ORNL projects that illustrate the use of integrated assessment approaches include environmental documentation for: (1) the Department of the Army`s Chemical Stockpile Disposal Program, (2) the Federal Energy Regulatory Commission`s licensing activities related to the Owens River Basin in eastern California and along a 500-mile reach of the upper Ohio River, and (3) the Nuclear Regulatory Commission`s decision regarding restart of the undamaged reactor (Unit 1) at Three Mile Island. Our discussion of these examples illustrates successful integrated assessment approaches and identifies new challenges facing integrated assessment activities.

    2012-11-01

    The principles and guidelines of the Brazilian Unified Health System (SUS) impose a healthcare service structure based on public policy networks which, combined with the financing model adopted, leads to market failings. This imposes barriers to the management of the public health system and the enactment of SUS objectives. The institutional characteristics and the heterogeneity of players, allied to the existence of different healthcare approaches, generate analytical complexity in the study of the global dynamics of the SUS network. There are limitations in the use of quantitative methods based on static analysis of retrospective SUS data. Thus, an approach taking SUS as a complex system using innovative quantitative methodology based on computational simulation is proposed. This paper sought to analyze challenges and possibilities of the combined application of cellular automata modeling and agent-based modeling for simulation of the evolution of the SUS healthcare service network. This approach should permit better understanding of the organization, heterogeneity and structural dynamics of the SUS service network and a minimization of the effects of market failings on the Brazilian health system.

    This paper presents a state-of-the-art survey of smartphone (SP)-based solutions for fall detection and prevention. Falls are considered as major health hazards for both the elderly and people with neurodegenerative diseases. To mitigate the adverse consequences of falling, a great deal of research has been conducted, mainly focused on two different approaches, namely, fall detection and fall prevention. Required hardware for both fall detection and prevention are also available in SPs. Consequently, researchers' interest in finding SP-based solutions has increased dramatically over recent years. To the best of our knowledge, there has been no published review on SP-based fall detection and prevention. Thus in this paper, we present the taxonomy for SP-based fall detection and prevention solutions and systematic comparisons of existing studies. We have also identified three challenges and three open issues for future research, after reviewing the existing articles. Our time series analysis demonstrates a trend towards the integration of external sensing units with SPs for improvement in usability of the systems. PMID:24759116

    As more and more individuals express themselves with tattoos and body piercings and push the envelope on what is deemed appropriate in the workplace, employers have an increased need for creation and enforcement of reasonable dress codes and appearance policies. As with any employment policy or practice, an appearance policy must be implemented and enforced without regard to an individual's race, color, gender, national origin, religion, disability, age, or other protected status. A policy governing dress and appearance based on the business needs of an employer that is applied fairly and consistently and does not have a disproportionate effect on any protected class will generally be upheld if challenged in court. By examining some of the more common legal challenges to dress codes and how courts have resolved the disputes, health care managers can avoid many potential problems. This article, the second part of a 3-part examination of dress codes and appearance policies, focuses on the issue of gender under the Civil Rights Act of 1964. Pertinent court cases that provide guidance for employers are addressed. PMID:24463587

    Research on health policies is considered essential to ensure the effectiveness and efficiency of public policies. Analyses of public health policies have various objectives, including helping to solve the problems for which the policy was originated. That objective faces two large obstacles: (1) the ambiguity and heterogeneity of the models applied for the analysis of public policies, conditions that hinder the selection of analytical methods and the assessment of the scope of the objective; and (2) the traditional methodological approaches that limit the capacity of analyses to help solve the problems detected. This paper reviews the epistemology of the predominant models of public health policy analysis in order to assess their scope and limitations. It concludes that the development of new conceptual approaches could improve the quality of research on public policies and their ability to favorably impact decisions. PMID:22910729

    Cognitive radio is widely expected to be the next Big Bang in wireless communications. Spectrum sensing, that is, detecting the presence of the primary users in a licensed spectrum, is a fundamental problem for cognitive radio. As a result, spectrum sensing has reborn as a very active research area in recent years despite its long history. In this paper, spectrum sensing techniques from the optimal likelihood ratio test to energy detection, matched filtering detection, cyclostationary detection, eigenvalue-based sensing, joint space-time sensing, and robust sensing methods are reviewed. Cooperative spectrum sensing with multiple receivers is also discussed. Special attention is paid to sensing methods that need little prior information on the source signal and the propagation channel. Practical challenges such as noise power uncertainty are discussed and possible solutions are provided. Theoretical analysis on the test statistic distribution and threshold setting is also investigated.

    Growing up in an era of video games and Web-based applications has primed current medical students to expect rapid, interactive feedback. To address this need, the A.T. Still University-School of Osteopathic Medicine in Arizona (Mesa) has developed and integrated a variety of approaches using technology-enhanced active learning for medical education (TEAL-MEd) into its curriculum. Over the course of 3 years (2010-2013), the authors facilitated more than 80 implementations of games and virtual patient simulations into the education of 550 osteopathic medical students. The authors report on 4 key aspects of the TEAL-MEd initiative, including purpose, portfolio of tools, progress to date regarding challenges and solutions, and future directions. Lessons learned may be of benefit to medical educators at academic and clinical training sites who wish to implement TEAL-MEd activities. PMID:25830576

    2016-01-01

    Background The notion of a patient-centered medical home features prominently in policy reform initiatives across the country, with both state and federal legislation focusing on this new model. We sought to understand the views of key stakeholders and to examine the challenging landscape facing policymakers and practitioners as they attempt to translate the medical home concept into widespread practice change. Methods We reviewed legislative documents from state legislative sessions in the year 2007 to identify pieces of legislation that included the medical home concept. Concurrently we conducted an in-depth qualitative analysis of de-identified field notes from a purposeful sample of semistructured interviews conducted with key stakeholders in Oregon after the passage of health reform legislation in 2007. Results Legislation that further defined and expounded on the medical home concept was introduced in states across the country in 2007, and some federal and state demonstration projects were already underway. However, we identified a number of barriers to widespread implementation of the medical home, most notably lack of a clear operational definition. Key stakeholders had widely disparate views about elements central to the success of medical home demonstrations, including delivery system reform, payment reform, and performance incentives for providers. Conclusions Since 2007 the concept of the medical home has gained increasing attention in health care reform debates. Our findings suggest that translating this concept into successful, widespread reform will require that policymakers build further consensus among key stakeholders and require them to address critical barriers to avoid repeating pitfalls of past reform efforts.

    Objective To report an in-depth analysis of policy change for integrated community case management of childhood illness (iCCM) in six sub-Saharan African countries. We analysed how iCCM policies developed and the barriers and facilitators to policy change. Methods Qualitative retrospective case studies drawing from document reviews, semi-structured interviews and in-country validation workshops were conducted in Burkina Faso, Kenya, Malawi, Mali, Mozambique and Niger. These countries were selected to maximise variation in iCCM policy status, community health worker (CHW) models and different African regions. Results Country iCCM policies evolved in an ad hoc fashion, but were substantially influenced by the history of primary health care and the nature of CHW programmes. Technical officers within Ministries of Health led iCCM policy change with support from international donors, but neither communities nor political leadership was mobilised. Concerns about achieving the Millennium Development Goals, together with recognition of the shortcomings of existing child health programmes, led to the adoption of iCCM policies. Availability of external financing played a critical role in facilitating policy change. Conclusions iCCM policy change has been promoted by international agencies, but national governments have struggled to align iCCM with country health systems. Greater investment is needed in tailoring global policy initiatives to match country needs. High-level, political ownership of iCCM policies could facilitate policy change, as could clearer strategies for ensuring the long-term sustainability of such policies. PMID:24750516

    The delivery of adequate health care to "all of the people" has become an increasing challenge in the United States. The problem of timely access to affordable health care is even more serious in Oklahoma. The University of Oklahoma-Tulsa Health Science Center, the OU College of Medicine-Tulsa, and Community HealthNET, Inc. have taken leadership roles in convening two Oklahoma Health Care Challenge summit meetings this past year. Tulsa community leaders are now addressing the seriousness of the local problem and, more importantly, are coming up with ways to alleviate it. The focus of the summits has centered on providing indigent care, which will provide relief to the Tulsa hospitals and physicians from the growing burden of charity care costs. The most beneficial results of these meetings have been a clearer definition of the problem specific to Tulsa, the recognition that the solution will require coalitions of multidisciplinary groups, and the realization that cooperation, as well as collaboration, is the key to success.

    Cardiac arrhythmias are a major contributor to population morbidity and mortality. Enormous advances in arrhythmia management have occurred over the 60 years since the founding of the Montreal Heart Institute, but important challenges remain. The purpose of this article is to identify the areas of cardiac arrhythmia therapy that need improvement and to discuss the evolving approaches that promise solutions. Challenges in diagnosis, detection, and risk-stratification include difficulties in separating benign from high-risk syncope and pinpointing the underlying causes, the detection of silent atrial fibrillation in patients at risk of stroke, and inadequate identification of sudden-death risk. Implantable devices are limited by the need for battery and device replacements, device complications like infection and dysfunction, and lead complications like fracture, infection, or displacement. Antiarrhythmic drug therapy, although widely used, is plagued by a very limited range of available agents, supply issues, insufficient efficacy, and significant adverse effect risk. Health economic concerns include the high cost of new technologies, challenges in establishing cost effectiveness, and restrictive practices of government or third-party payers. Major improvements in arrhythmia management can be expected from new discoveries and technological developments in genetics, innovative diagnostic tools for arrhythmia monitoring, imaging and analysis, new approaches to antiarrhythmic drug development, biological therapies, and continuing improvement in implantable device technology like further miniaturization, leadless technology, and use of novel energy sources. As exciting as the developments in arrhythmia management have been in the past, we can look forward to exponential improvement in our ability to manage arrhythmia patients in the near future.

    Ensuring interoperability between WebGIS applications is essential for maximizing access to data, data sharing, and data manipulation. Interoperability is maximized through the adoption of best practices, use of open standards, and utilization of spatial data infrastructure (SDI). While many of the interoperability challenges like infrastructure, data exchange, and file formats are common between applications, some regions like the Arctic present specific challenges including the need for presenting data in one or more polar projections. This paper describes the Arctic Research Mapping Application (ARMAP) suite of online interactive maps, web services, and virtual globes (the ARMAP suite; http://armap.org/) and several of the interoperability challenges and solutions encountered in development to date. ARMAP is a unique science and logistic tool supporting United States and international Arctic science by providing users with the ability to access, query, and browse information and data. Access to data services include a text-based search utility, an Internet Map Server client (ArcIMS), a lightweight Flex client, ArcGIS Explorer and Google Earth virtual globes, and Open Geospatial Consortium ( OGC) compliant web services, such as Web Map Service (WMS) and Web Feature Service (WFS). Through the ARMAP suite, users can view a variety of Arctic map layers and explore pertinent information about United States Arctic research efforts. The Arctic Research Logistics Support Service (ARLSS) database is the informational underpinning of ARMAP. Avoiding duplication of effort has been a key priority in the development of the ARMAP applications. The ARMAP suite incorporates best practices that facilitate interoperability such as Federal Geographic Data Committee (FGDC) metadata standards, web services for embedding external data and serving framework layers, and open standards such as Open Geospatial Consortium ( OGC) compliant web services.

    Water resource scientists face complex tasks in evaluating aspects of water projects, but relatively few assessment procedures have been applied and accepted as standard applications. Decision-makers often rely on environmental assessments to evaluate the value and operation of projects. There is often confusion about scientists' role in policy decisions. The scientist can affect policy-making as an expert withess, an advocate or a surrogate. By understanding the policy process, scientists can make their work more “policy relevant.” Using the Terror Lake hydro project in Alaska as a guide, three lessons are discussed: (1) not all problems are able to be solved with technology; (2) policy-relevant technology is rarely imposed on a problem; and (3) the scientist need not just react to the policy process, but can have an impact on how that process unfolds.

    Nurses and midwives play a key role in providing universal maternal, child and family health services in Australia. However, the Australian federation of states and territories has resulted in policy frameworks that differ across jurisdictions and services that are fragmented across disciplines and sectors. This paper reports the findings of a study that reviewed and synthesised current Australian service policy or frameworks for maternity and child health services in order to identify the degree of commonality across jurisdictions and the compatibility with international research on child development. Key maternity and child health service policy documents in each jurisdiction were sourced. The findings indicate that current policies were in line with international research and policy directions, emphasising prevention and early intervention, continuity of care, collaboration and integrated services. The congruence of policies suggests the time is right to consider the introduction of a national approach to universal maternal, child health services. PMID:22545909

    Background Patients requiring daily intravenous (IV) home parenteral nutrition (HPN) would benefit from in-home professional observation to improve self-care, to assess, detect and prevent serious complications. Aims The study aims are to assess the viability and utility of conducting mobile healthcare (mHealth) videoconference assessments with patients managing lifelong daily 12-hour IV nutrition infusions in their homes. The challenges and solutions to implementing mobile personal computer (PC) tablet based clinic appointments are described. Methods A wireless Apple iPad Mini™ mobile touch-screen tablet computer with 5 mega-pixel camera was loaned to patients. Each tablet had Polycom RealPresence software and a fourth generation (4G) mobile telecommunications data plan. These supported audio-visual mobile videoconferencing encrypted connections between health professionals in their offices and HPN patients and their family members in their homes. Patients’ and professionals’ evaluations of their mHealth clinic experiences are collected. Results Patients (mean age = 41.9, SD = 2.8 years) had been prescribed 12-hour home parenteral nutrition (HPN) infusions daily due short bowel disorders. Patients had been on HPN from 1 to 10 years (M=4, SD=3.6). Evaluation of clinic appointments revealed that 100% of the patients (n=45) and the professionals (n=6) indicated that they can clearly hear and easily see one another. The mHealth audio-visual interactions were highly rated by patients and family members. Professionals highly rated their ability to obtain a medical history and visual inspection of patients. Several challenges were identified and recommendations for resolutions are described. Discussion All patients and professionals highly rated the iPad mHealth clinic appointments for convenience and ease of communicating between homes and offices. An important challenge for all mHealth visits is the clinical professional’s ability to make clinically accurate

    The energy challenge is central to the most important strategic problems facing the United States and the world. It is increasingly clear that even large-scale deployments of the best technologies available today cannot meet the rising energy demands of a growing world population. Achieving a secure and sustainable energy future will require full utilization of, and substantial improvements in, a comprehensive portfolio of energy systems and technologies. This goal is complicated by several factors. First, energy strategies are inextricably linked to national security and health issues. Second, in developing and deploying energy technologies, it is vital to consider not only environmental issues, such as global climate change, but also economic considerations, which strongly influence both public and political views on energy policy. Third, a significant and sustained effort in basic and applied research and development (R&D) will be required to deliver the innovations needed to ensure a desirable energy future. Innovations in materials science and engineering are especially needed to overcome the limits of essentially all energy technologies. A wealth of historical evidence demonstrates that such innovations are also the key to economic prosperity. From the development of the earliest cities around flint-trading centers, to the Industrial Revolution, to today’s silicon-based global economy, the advantage goes to those who lead in exploiting materials. I view our challenge by considering the rate of innovation and the transition of discovery to the marketplace as the relationship among R&D investment, a skilled and talented workforce, business innovations, and the activities of competitors. Most disturbing in analyzing this relationship is the need for trained workers in science, technology, engineering, and mathematics (STEM). To develop the STEM workforce needed for innovation, we need sustainable, positive change in STEM education at all levels from preschool

From the development of the earliest cities around flint-trading centers, to the Industrial Revolution, to today’s silicon-based global economy, the advantage goes to those who lead in exploiting materials. I view our challenge by considering the rate of innovation and the transition of discovery to the marketplace as the relationship among R&D investment, a skilled and talented workforce, business innovations, and the activities of competitors. Most disturbing in analyzing this relationship is the need for trained workers in science, technology, engineering, and mathematics (STEM). To develop the STEM workforce needed for innovation, we need sustainable, positive change in STEM education at all levels from preschool

    As more and more individuals choose to express themselves and their religious beliefs with headwear, jewelry, dress, tattoos, and body piercings and push the envelope on what is deemed appropriate in the workplace, employers have an increased need for creation and enforcement of reasonable dress codes and appearance policies. As with any employment policy or practice, an appearance policy must be implemented and enforced without regard to an individual's race, color, sex, national origin, religion, disability, age, or any other protected status. A policy governing dress and appearance based on the business needs of an employer that is applied fairly and consistently and does not have a disproportionate effect on any protected class will generally be upheld if challenged in court. By examining some of the more common legal challenges to dress codes and how courts have resolved the disputes, health care managers can avoid many potential problems. This article addresses the issue of religious discrimination focusing on dress and appearance and some of the court cases that provide guidance for employers. PMID:24168864

  14. Big Data challenges and solutions in building the Global Earth Observation System of Systems (GEOSS)

    2014-05-01

    . The current implementation of GEOSS already addresses several big data challenges. In particular, the brokered architecture adopted in the GEOSS Common Infrastructure with the deployment of the GEO DAB (Discovery and Access Broker) allows to connect more than 20 big EO infrastructures while keeping them autonomous as required by their own mandate and governance. They make more than 60 million of unique resources discoverable and accessible through the GEO Portal. Through the GEO DAB, users are able to seamlessly discover resources provided by different infrastructures, and access them in a harmonized way, collecting datasets from different sources on a Common Environment (same coordinate reference system, spatial subset, format, etc.). Through the GEONETCast system, GEOSS is also providing a solution related to the Velocity challenge, for delivering EO resources to developing countries with low bandwidth connections. Several researches addressing other Big data Vs challenges in GEOSS are on-going, including quality representation for Veracity (as in the FP7 GeoViQua project), brokering big data analytics platforms for Velocity, and support of other EO resources for Variety (such as modelling resources in the Model Web).

  15. Novel developments in benthic modelling to address scientific and policy challenges

    2016-04-01

    Understanding the role of benthic systems in supporting, regulating and providing marine ecosystem services requires better understanding of their functioning and their response and resilience to stressors. Novel observational methods for the investigation of dynamics of benthic-pelagic coupling in shelf seas are being developed and new data is being collected. Therefore there is an increasing demand for robust representation of benthic processes in marine biogeochemical and ecosystem models, which would improve our understanding of whole systems and benthic-pelagic coupling, rather than act as mere closure terms for pelagic models. However, for several decades development of benthic models has lagged behind their pelagic counterparts. To address contemporary scientific, policy and societal challenges, the biogeochemical and ecological model ERSEM (European Regional Seas Ecosystem Model), including its benthic sub-model, was recently recoded in a scalable and modular format adopting the approach of FABM (Framework for Aquatic Biogeochemical Models). Within the Shelf Sea Biogeochemistry research programme, a series of additional processes have been included, such as a sedimentary carbonate system, a resuspendable fluff layer, and the simulation of advective sediments. It was shown that the inclusion of these processes changes the dynamics of benthic-pelagic fluxes as well as modifying the benthic food web. Comparison of model results with in-situ data demonstrated a general improvement of model performance and highlighted the importance of the benthic system in overall ecosystem dynamics. As an example, our simulations have shown that inclusion of a resuspendable fluff layer facilitates regeneration of inorganic nutrients in the water column due to degradation of resuspended organic material by pelagic bacteria. Moreover, the composition of fluff was found to be important for trophic interactions, and therefore indirectly affects benthic community composition. Where

  16. A mixed-methods study of the implementation of medication adherence policy solutions: how do European countries compare?

    Clyne, Wendy; McLachlan, Sarah

    2015-01-01

    Objectives We describe a key informant study that invited national medicines policy leads for the European Union member states to self-assess the level of implementation of medicines adherence initiatives in their country and the adequacy of that implementation. Interviews with medicines policy leads enabled in-depth understanding of the variation in adherence support across nations and the ways in which different nations prioritize, plan, and implement medicines adherence systems and services. Methods Ten national policy leads (Bulgaria, Denmark, Estonia, Finland, Germany, Ireland, Latvia, Lithuania, Malta, and the Netherlands) completed a self-assessment survey, and seven (Estonia, Finland, Germany, Ireland, Lithuania, Malta, and the Netherlands) engaged in a follow-up interview. Key findings Policy leads varied in the level of implementation of medication adherence solutions that they reported in their nations; most initiatives were aimed directly at patients with few initiatives at government or health care commissioner levels of action. Policy leads reported insufficient implementation of medication adherence initiatives across all potential domains. Barriers to implementation included lack of resources, strategic planning, evidence to support action, the “hidden” nature of medication adherence within policy work, and dispersed responsibility for medication adherence as a policy and practice theme. Conclusion This study has international significance and summarizes the emergent characteristics of nations with and without coordinated medication adherence activity. We highlight the importance of sharing good practice in policy formulation and implementation for medication adherence. PMID:26604703

  17. Is it possible to give scientific solutions to Grand Challenges? On the idea of grand challenges for life science research.

    PubMed

    Efstathiou, Sophia

    2016-04-01

    This paper argues that challenges that are grand in scope such as "lifelong health and wellbeing", "climate action", or "food security" cannot be addressed through scientific research only. Indeed scientific research could inhibit addressing such challenges if scientific analysis constrains the multiple possible understandings of these challenges into already available scientific categories and concepts without translating between these and everyday concerns. This argument builds on work in philosophy of science and race to postulate a process through which non-scientific notions become part of science. My aim is to make this process available to scrutiny: what I call founding everyday ideas in science is both culturally and epistemologically conditioned. Founding transforms a common idea into one or more scientifically relevant ones, which can be articulated into descriptively thicker and evaluatively deflated terms and enable operationalisation and measurement. The risk of founding however is that it can invisibilise or exclude from realms of scientific scrutiny interpretations that are deemed irrelevant, uninteresting or nonsensical in the domain in question-but which may remain salient for addressing grand-in-scope challenges. The paper considers concepts of "wellbeing" in development economics versus in gerontology to illustrate this process. PMID:26698954

    Jacobs, David E.; Kelly, Tom; Sobolewski, John

    2007-01-01

    We describe the successes and challenges faced by federal and local government agencies in the United States as they have attempted in recent years to connect public and environmental health, housing, community development, and building design with environmental, housing, and building laws, codes, and policies. These policies can either contribute to or adversely affect human physical and mental health, with important implications for economic viability, research, policy development, and overall social stability and progress. Policy impediments include tension between housing affordability and health investment that causes inefficient cost-shifting, privacy issues, unclear statutory authority, and resulting gaps in responsibility for housing, indoor air, and the built environment. We contrast this with other environmental frameworks such as ambient air and water quality statutes where the concept of “shared commons” and the “polluter pays” is more robust. The U.S. experiences in childhood lead poisoning prevention, indoor air, and mold provide useful policy insights. Local programs can effectively build healthy homes capacity through local laws and housing codes. The experience of coordinating remediation for mold, asthma triggers, weatherization, and other healthy housing improvements in Cuyahoga County, Ohio, is highlighted. The U.S. experience shows that policymakers should adopt a prevention-oriented, comprehensive multi-disciplinary approach at all levels of government to prevent unhealthy buildings, houses, and communities.

  20. Climate Change Adaptation Among Tibetan Pastoralists: Challenges in Enhancing Local Adaptation Through Policy Support

    NASA Astrophysics Data System (ADS)

    Fu, Yao; Grumbine, R. Edward; Wilkes, Andreas; Wang, Yun; Xu, Jian-Chu; Yang, Yong-Ping

    2012-10-01

    While researchers are aware that a mix of Local Ecological Knowledge (LEK), community-based resource management institutions, and higher-level institutions and policies can facilitate pastoralists' adaptation to climate change, policy makers have been slow to understand these linkages. Two critical issues are to what extent these factors play a role, and how to enhance local adaptation through government support. We investigated these issues through a case study of two pastoral communities on the Tibetan Plateau in China employing an analytical framework to understand local climate adaptation processes. We concluded that LEK and community-based institutions improve adaptation outcomes for Tibetan pastoralists through shaping and mobilizing resource availability to reduce risks. Higher-level institutions and policies contribute by providing resources from outside communities. There are dynamic interrelationships among these factors that can lead to support, conflict, and fragmentation. Government policy could enhance local adaptation through improvement of supportive relationships among these factors. While central government policies allow only limited room for overt integration of local knowledge/institutions, local governments often have some flexibility to buffer conflicts. In addition, government policies to support market-based economic development have greatly benefited adaptation outcomes for pastoralists. Overall, in China, there are still questions over how to create innovative institutions that blend LEK and community-based institutions with government policy making.

  2. Rationality versus reality: the challenges of evidence-based decision making for health policy makers

    PubMed Central

    2010-01-01

    Background Current healthcare systems have extended the evidence-based medicine (EBM) approach to health policy and delivery decisions, such as access-to-care, healthcare funding and health program continuance, through attempts to integrate valid and reliable evidence into the decision making process. These policy decisions have major impacts on society and have high personal and financial costs associated with those decisions. Decision models such as these function under a shared assumption of rational choice and utility maximization in the decision-making process. Discussion We contend that health policy decision makers are generally unable to attain the basic goals of evidence-based decision making (EBDM) and evidence-based policy making (EBPM) because humans make decisions with their naturally limited, faulty, and biased decision-making processes. A cognitive information processing framework is presented to support this argument, and subtle cognitive processing mechanisms are introduced to support the focal thesis: health policy makers' decisions are influenced by the subjective manner in which they individually process decision-relevant information rather than on the objective merits of the evidence alone. As such, subsequent health policy decisions do not necessarily achieve the goals of evidence-based policy making, such as maximizing health outcomes for society based on valid and reliable research evidence. Summary In this era of increasing adoption of evidence-based healthcare models, the rational choice, utility maximizing assumptions in EBDM and EBPM, must be critically evaluated to ensure effective and high-quality health policy decisions. The cognitive information processing framework presented here will aid health policy decision makers by identifying how their decisions might be subtly influenced by non-rational factors. In this paper, we identify some of the biases and potential intervention points and provide some initial suggestions about how the

    Even though each of us shares more than 99% of the DNA sequences in our genome, there are millions of sequence codes or structure in small regions that differ between individuals, giving us different characteristics of appearance or responsiveness to medical treatments. Currently, genetic variants in diseased tissues, such as tumors, are uncovered by exploring the differences between the reference genome and the sequences detected in the diseased tissue. However, the public reference genome was derived with the DNA from multiple individuals. As a result of this, the reference genome is incomplete and may misrepresent the sequence variants of the general population. The more reliable solution is to compare sequences of diseased tissue with its own genome sequence derived from tissue in a normal state. As the price to sequence the human genome has dropped dramatically to around $1000, it shows a promising future of documenting the personal genome for every individual. However, de novo assembly of individual genomes at an affordable cost is still challenging. Thus, till now, only a few human genomes have been fully assembled. In this review, we introduce the history of human genome sequencing and the evolution of sequencing platforms, from Sanger sequencing to emerging “third generation sequencing” technologies. We present the currently available de novo assembly and post-assembly software packages for human genome assembly and their requirements for computational infrastructures. We recommend that a combined hybrid assembly with long and short reads would be a promising way to generate good quality human genome assemblies and specify parameters for the quality assessment of assembly outcomes. We provide a perspective view of the benefit of using personal genomes as references and suggestions for obtaining a quality personal genome.

    2016-04-01

    The economic upturn of the past 200 years would not have been conceivable without fossil resources such as coal and oil. However, the fossil-based economy increasingly reaches its limits and displays contradictions. Bioeconomy, strategically combining economy and ecology willing to make biobased and sustainable growth possible, is promising to make a significant contribution towards solving these issues. In this context, microbial bioconversions are promising to support partially the increasing need for materials and fuels starting from fresh, preferably waste, biomass. Butanol is a very attractive molecule finding applications both as a chemical platform and as a fuel. Today it principally derives from petroleum, but it also represents the final product of microbial catabolic pathways. Because of the need to maximize yield, titer and productivity to make the production competitive and viable, the challenge is to transform a robustly regulated metabolic network into the principal cellular activity. However, this goal can only be accomplished by a profound understanding of the cellular physiology, survival strategy and sensing/signalling cascades. Here, we shortly review on the natural cellular pathways and circumstances that lead to n-butanol accumulation, its physiological consequences that might not match industrial needs and on possible solutions for circumventing these natural constraints.

    2015-12-01

    CERN's accelerator complex generates a very large amount of data. A large volumen of heterogeneous data is constantly generated from control equipment and monitoring agents. These data must be stored and analysed. Over the decades, CERN's researching and engineering teams have applied different approaches, techniques and technologies for this purpose. This situation has minimised the necessary collaboration and, more relevantly, the cross data analytics over different domains. These two factors are essential to unlock hidden insights and correlations between the underlying processes, which enable better and more efficient daily-based accelerator operations and more informed decisions. The proposed Big Data Analytics as a Service Infrastructure aims to: (1) integrate the existing developments; (2) centralise and standardise the complex data analytics needs for CERN's research and engineering community; (3) deliver real-time, batch data analytics and information discovery capabilities; and (4) provide transparent access and Extract, Transform and Load (ETL), mechanisms to the various and mission-critical existing data repositories. This paper presents the desired objectives and properties resulting from the analysis of CERN's data analytics requirements; the main challenges: technological, collaborative and educational and; potential solutions.

    Clinical nurse leaders such as clinical nurse consultants are required to conduct research and incorporate outcomes of this research into their every day practice. However, undertaking research presents issues for cardiac rehabilitation clinical nurse consultants because they may have competing demands, difficulty with finding replacements and may be relatively isolated from other researchers. The solution to this situation is the formation of a collaborative research team with other cardiac rehabilitation clinical nurse consultants, with the inclusion of an experienced university academic as a mentor for the cardiac rehabilitation clinical nurse consultants working in an Area Health Service encompassing both rural and metropolitan hospitals in New South Wales, Australia. The related research project aimed to evaluate and improve the clients' knowledge and practices related to the use of sublingual glyceryl trinitrate. The team's experiences and suggestions for clinical nurse Leaders are presented in this paper. Essential team characteristics include having shared motivation, good communication practices, flexibility and tolerance, an effective team size, achieving success, willingness to accept challenges and an experienced mentor. The benefits of developing a collaborative team for research led by clinical nurse consultants in cardiac rehabilitation by far outweigh the time and effort involved in the process. PMID:24596995

    The particular challenge of the analysis of optical absorption and Raman spectroscopic data measured from protein crystals and how the SLS-APE software toolbox supports scientists in dealing with such data is described. Combining macromolecular crystallography with in crystallo micro-spectrophotometry yields valuable complementary information on the sample, including the redox states of metal cofactors, the identification of bound ligands and the onset and strength of undesired photochemistry, also known as radiation damage. However, the analysis and processing of the resulting data differs significantly from the approaches used for solution spectrophotometric data. The varying size and shape of the sample, together with the suboptimal sample environment, the lack of proper reference signals and the general influence of the X-ray beam on the sample have to be considered and carefully corrected for. In the present article, how to characterize and treat these sample-dependent artefacts in a reproducible manner is discussed and the SLS-APEin situ, in crystallo optical spectroscopy data-analysis toolbox is demonstrated.

    Besides the special primary lightning protection of extremely high towers, huge office and governmental buildings, large industrial plants and resident parks most of the challenges were connected to the secondary lightning protection of sensitive devices in Information and Communication Technology. The 70 year history of Budapest School of Lightning Protection plays an important role in the research and education of lightning and development of lightning protection. Among results and solutions the Rolling Sphere designing method (RS) and the Probability Modulated Attraction Space (PMAS) theory are detailed. As a new field Preventive Lightning Protection (PLP) has been introduced. The PLP method means the use of special preventive actions only for the duration of the thunderstorm. Recently several non-conventional lightning protection techniques have appeared as competitors of the air termination systems formed of conventional Franklin rods. The questionable steps, non-conventional lightning protection systems reported in the literature are the radioactive lightning rods, Early Streamer Emission (ESE) rods and Dissipation Arrays (sometimes called Charge Transfer Systems).

    The trend for dense deployment in future 5G mobile communication networks makes current wired backhaul infeasible owing to the high cost. Millimetre-wave (mm-wave) communication, a promising technique with the capability of providing a multi-gigabit transmission rate, offers a flexible and cost-effective candidate for 5G backhauling. By exploiting highly directional antennas, it becomes practical to cope with explosive traffic demands and to deal with interference problems. Several advancements in physical layer technology, such as hybrid beamforming and full duplexing, bring new challenges and opportunities for mm-wave backhaul. This article introduces a design framework for 5G mm-wave backhaul, including routing, spatial reuse scheduling and physical layer techniques. The associated optimization model, open problems and potential solutions are discussed to fully exploit the throughput gain of the backhaul network. Extensive simulations are conducted to verify the potential benefits of the proposed method for the 5G mm-wave backhaul design. PMID:27322265

    In the nineties, x-ray computed tomography, commonly referred to as CT, seemed to be on the track to become old technology, bound to be replaced by more sophisticated techniques such as magnetic resonance imaging, due in particular to the harmful effects of x-ray radiation exposure. Yet, the new century brought with it new technology that allowed a complete change in trends and re-affirmed CT as an essential tool in radiology. For instance, the popularity of CT in 2007 was such that approximately 68.7 million CT examinations were performed in the United States, which was nearly 2.5 times the number of magnetic resonance (MRI) examinations. More than that, CT has expanded beyond its conventional diagnostic role; CT is now used routinely in interventional radiology and also in radiation therapy treatment. The technology advances that allowed the revival of CT are those that made fast, accurate cone-beam data acquisition possible. Nowadays, cone-beam data acquisition allows scanning large volumes with isotropic sub-millimeter spatial resolution in a very fast time, which can be as short as 500ms for cardiac imaging. The principles of cone-beam imaging will be first reviewed. Then a discussion of its applications will be given. Old and new challenges will be presented along the way with current solutions.

    Many drivers of mangrove forest loss operate over large scales and are most effectively addressed by policy interventions. However, conflicting or unclear policy objectives exist at multiple tiers of government, resulting in contradictory management decisions. To address this, we considered four approaches that are being used increasingly or could be deployed in Southeast Asia to ensure sustainable livelihoods and biodiversity conservation. First, a stronger incorporation of mangroves into marine protected areas (that currently focus largely on reefs and fisheries) could resolve some policy conflicts and ensure that mangroves do not fall through a policy gap. Second, examples of community and government comanagement exist, but achieving comanagement at scale will be important in reconciling stakeholders and addressing conflicting policy objectives. Third, private-sector initiatives could protect mangroves through existing and novel mechanisms in degraded areas and areas under future threat. Finally, payments for ecosystem services (PES) hold great promise for mangrove conservation, with carbon PES schemes (known as blue carbon) attracting attention. Although barriers remain to the implementation of PES, the potential to implement them at multiple scales exists. Closing the gap between mangrove conservation policies and action is crucial to the improved protection and management of this imperiled coastal ecosystem and to the livelihoods that depend on them.

    2008-01-01

    Despite the fact that diabetes and other non-communicable diseases represent a significant proportion of the global burden of disease, proportionate global action has not occurred. A 2003 article reported on global constraints to the implementation of effective policies to curb non-communicable disease epidemics. These constraints include a lack of global advocacy, insufficient attention from funding agencies and governments, partnerships and interactions, capacity and resources, and global norms and standards, as well as orientation of health services to acute care. Building on these ideas, this paper will review the progress that has been made with regards to each constraint, focusing on the International Diabetes Federation's Unite for Diabetes campaign and United Nations resolution on diabetes to show how this event – driven by globalization – has helped remove some of these barriers. Additional progress in diabetes and NCD prevention and control is also highlighted. The paper concludes by outlining what still needs to happen for globalization to be an effective solution for diabetes and non-communicable disease prevention and control. PMID:18284685

    The objectives of this article are to describe the evidence base for alcohol policy in the Americas, to evaluate the extent to which national policies are likely to have an impact on public health, and to identify areas where alcohol policies could be improved. The paper begins with a brief review of epidemiological surveys of the prevalence of alcohol problems in the Americas. This is followed by an analysis of 32 prevention strategies and interventions in terms of the evidence for their effectiveness, amount of research support, cost to implement, and other feasibility issues. Overall, the strategies and interventions with the greatest amount of empirical support are low blood alcohol concentration levels for driving while intoxicated, controls on alcohol availability, age limits on alcohol purchases, and relatively high alcohol prices. The implications of the evidence are next discussed in relation to alcohol policy initiatives in the Americas, based on an analysis of the extent to which strategies and interventions currently used in 25 countries of the Americas are likely to have a public health impact on alcohol-related problems. The countries that have adopted the policies with the highest expected impact overall are Colombia, Costa Rica, Venezuela, and El Salvador. Nevertheless, the analysis indicates that almost all the countries of the Americas could improve the likelihood of preventing alcohol-related problems. Policy efforts in the developing countries of Latin America should focus on improving countermeasures against driving while intoxicated, measures that alter the drinking context, and limits on physical availability. For the developed, high-income countries of North America the goal should be to prevent deterioration of current drinking patterns and to reduce the overall volume of drinking. Given the low to moderate cost of many of the policies reviewed in this article, it now seems possible for communities and nations to substantially reduce the

  17. Incorporating indigenous rights and environmental justice into fishery management: comparing policy challenges and potentials from Alaska and Hawai'i.

    PubMed

    Richmond, Laurie

    2013-11-01

    Colonial processes including the dispossession of indigenous lands and resources and the development of Western management institutions to govern the use of culturally important fish resources have served in many ways to marginalize indigenous interests within the United States fisheries. In recent years, several US fishery institutions have begun to develop policies that can confront this colonial legacy by better accommodating indigenous perspectives and rights in fishery management practices. This paper analyzes two such policies: the 2005 community quota entity program in Alaska which permits rural communities (predominantly Alaska Native villages) to purchase and lease commercial halibut fishing privileges and the 1994 State of Hawai'i community-based subsistence fishing area (CBSFA) legislation through which Native Hawaiian communities can designate marine space near their community as CBSFAs and collaborate with the state of Hawai'i to manage those areas according to traditional Hawaiian practices. The analysis reveals a striking similarity between the trajectories of these two policies. While they both offered significant potential for incorporating indigenous rights and environmental justice into state or federal fishery management, they have so far largely failed to do so. Environmental managers can gain insights from the challenges and potentials of these two policies. In order to introduce meaningful change, environmental policies that incorporate indigenous rights and environmental justice require a commitment of financial and institutional support from natural resource agencies, a commitment from indigenous groups and communities to organize and develop capacity, and careful consideration of contextual and cultural factors in the design of the policy framework.

    This paper analyzes Colombia's space policy: its successes, its failures and what it still needs to achieve. The paper examines the interaction among the different players, and how this policy contributes to economic and social development of the country. And postulates that, unless a real national plan of action, with specific milestones and budget as well as a managing agency are developed, this policy may be in danger of disappearing. The Colombian Space Commission (Comisión Colombiana del Espacio, or CCE) was created by Presidential Decree 2442 in 2006. It is a multi-sectorial entity, in charge of coordinating, planning, and leading in the implementation of national policies for the development and application of space technologies. The CCE was also charged with the drafting of plans and programs in this field. The CCE began with only a few members (15) and today is comprised of 47 members: 13 ministries, 4 administrative departments, another 21 governmental entities and 9 universities, the latter acting as consultants. The Vice-President of the Republic is the President of the CCE. These different actors gave great importance to the development of Colombia's space sector, and 6 years later, they are continuing support and development the country's space policy. This analysis takes into account three aspects: first, achieving the objectives of the CCE: the creation and development of a national space policy for Colombia; secondly, focussing on “target groups” and “end users”; and thirdly, the “outcomes” or achievements to date. Some conclusions are worth highlighting: first, the warm reception and support of the CCE by both the public and private sectors on high levels, but the poor knowledge of the national space policy by the Colombian people and the small and medium companies. Secondly, in the context of public policy [9], the strategic plan called “National Policy in regard to Space Activities”, is caught between two phases: the formulation

    Re-democratization has transformed the social agenda and the role of the state in Latin America with a growing commitment to health equity and social justice, yet these aspirations are strained by the region´s profound socioeconomic inequalities. Efforts to provide universal coverage to the right to health have led to the development of a variety of public policies, whose scope depends on how the concepts of health and equity are understood. In general, policy action has centered on health system reforms and only recently on integrated intersectorial action to address wider social determinants of health, particularly structural determinants. Furthermore, if the goal is health equity the predominant minimum standards approach cannot be the final answer, but only a step on the road to equality. Finally, realizing universal coverage of the right to health through public policy requires the strengthening of governmental institutional capacities with an intersectorial and participatory lens.

    In this article, we review recent research on mental health in the Caribbean. Three major themes emerge: (a) the effects of colonialism on the Caribbean psyche; (b) decolonization of psychiatric public policy, including innovative treatment approaches, deinstitutionalization, and community and policy responses to mental health issues; and (c) the nature and epidemiology of psychiatric pathology among contemporary Caribbean people, with particular focus on migration, genetic versus social causation of psychosis and personality disorders, and mechanisms of resilience and social capital. Caribbean transcultural psychiatry illustrates the principles of equipoise unique to developing countries that protect the wellness and continued survival of postcolonial Caribbean people.

    Backgound Sulphadoxine/sulphalene-pyrimethamine (SP) was adopted in Kenya as first line therapeutic for uncomplicated malaria in 1998. By the second half of 2003, there was convincing evidence that SP was failing and had to be replaced. Despite several descriptive investigations of policy change and implementation when countries moved from chloroquine to SP, the different constraints of moving to artemisinin-based combination therapy (ACT) in Africa are less well documented. Methods A narrative description of the process of anti-malarial drug policy change, financing and implementation in Kenya is assembled from discussions with stakeholders, reports, newspaper articles, minutes of meetings and email correspondence between actors in the policy change process. The narrative has been structured to capture the timing of events, the difficulties and hurdles faced and the resolutions reached to the final implementation of a new treatment policy. Results Following a recognition that SP was failing there was a rapid technical appraisal of available data and replacement options resulting in a decision to adopt artemether-lumefantrine (AL) as the recommended first-line therapy in Kenya, announced in April 2004. Funding requirements were approved by the Global Fund to Fight AIDS, Tuberculosis and Malaria (GFATM) and over 60 million US$ were agreed in principle in July 2004 to procure AL and implement the policy change. AL arrived in Kenya in May 2006, distribution to health facilities began in July 2006 coincidental with cascade in-service training in the revised national guidelines. Both training and drug distribution were almost complete by the end of 2006. The article examines why it took over 32 months from announcing a drug policy change to completing early implementation. Reasons included: lack of clarity on sustainable financing of an expensive therapeutic for a common disease, a delay in release of funding, a lack of comparative efficacy data between AL and

    PubMed Central

    2010-01-01

    Background A traditional pathway for developing new health products begins with public research institutes generating new knowledge, and ends with the private sector translating this knowledge into new ventures. But while public research institutes are key drivers of basic research in sub-Saharan Africa, the private sector is inadequately prepared to commercialize ideas that emerge from these institutes, resulting in these institutes taking on the role of product development themselves to alleviate the local disease burden. In this article, the case study method is used to analyze the experience of one such public research institute: the Kenya Medical Research Institute (KEMRI). Discussion Our analysis indicates that KEMRI’s product development efforts began modestly, and a manufacturing facility was constructed with a strategy for the facility’s product output which was not very successful. The intended products, HIV and Hepatitis B diagnostic kits, had a short product life cycle, and an abrupt change in regulatory requirements left KEMRI with an inactive facility. These problems were the result of poor innovation management capacity, variability in domestic markets, lack of capital to scale up technologies, and an institutional culture that lacked innovation as a priority. However, KEMRI appears to have adapted by diversifying its product line to mitigate risk and ensure continued use of its manufacturing facility. It adopted an open innovation business model which linked it with investors, research partnerships, licensing opportunities, and revenue from contract manufacturing. Other activities that KEMRI has put in place over several years to enhance product development include the establishment of a marketing division, development of an institutional IP policy, and training of its scientists on innovation management. Summary KEMRI faced many challenges in its attempt at health product development, including shifting markets, lack of infrastructure

    Recent advances in high-throughput technologies enable quantitative monitoring of the abundance of various biological molecules and allow determination of their variation between biological states on a genomic scale. Two popular platforms areDNA microarrays to measure messenger RNA transcript levels, and gel-free proteomic analyses to determine protein abundance. Obviously, no single approach can fully unravel the complexities of fundamental biology and it is equally clear that integrative analysis of multiple levels of gene expression would be valuable in this endeavor. However, most integrative transcriptomic and proteomic studies have thus far either failed to find a correlation or have only observed a weak correlation. It is evident that this failure is not biologically based, but rather is related the inadequacy of available statistical tools to compensate for biases in the data collection methodologies. To address this issue, attempts have recently been made to systematically investigate the correlation patterns between transcriptomic and proteomic datasets, and to develop more sophisticated statistical tools to improve the chances of capturing a relationship. The goal of these investigations is to enhance our understanding of the relationship between transcriptome and proteome data so that integrative analyses may be utilized to reveal new biological insights that are not accessible through one dimensional datasets. In this review, we outline some of the challenges associated with integrative analyses and present some preliminary solutions based on progress being made in recent years. In addition, some new applications of integrated transcriptomic and proteomic analysis to the investigation of post-transcriptional regulation will also be discussed.

    The analysis of microbial assemblages in industrial, marine, and medical systems can inform decisions regarding quality control or mitigation. Modern molecular approaches to detect, characterize, and quantify microorganisms provide rapid and thorough measures unbiased by the need for cultivation. The requirement of timely extraction of high quality nucleic acids for molecular analysis is faced with specific challenges when used to study the influence of microorganisms on oil production. Production facilities are often ill equipped for nucleic acid extraction techniques, making the preservation and transportation of samples off-site a priority. As a potential solution, the possibility of extracting nucleic acids on-site using automated platforms was tested. The performance of two such platforms, the Fujifilm QuickGene-Mini80™ and Promega Maxwell®16 was compared to a widely used manual extraction kit, MOBIO PowerBiofilm™ DNA Isolation Kit, in terms of ease of operation, DNA quality, and microbial community composition. Three pipeline biofilm samples were chosen for these comparisons; two contained crude oil and corrosion products and the third transported seawater. Overall, the two more automated extraction platforms produced higher DNA yields than the manual approach. DNA quality was evaluated for amplification by quantitative PCR (qPCR) and end-point PCR to generate 454 pyrosequencing libraries for 16S rRNA microbial community analysis. Microbial community structure, as assessed by DGGE analysis and pyrosequencing, was comparable among the three extraction methods. Therefore, the use of automated extraction platforms should enhance the feasibility of rapidly evaluating microbial biofouling at remote locations or those with limited resources. PMID:23168231

    While policy changes toward early extubation in the operating room (OR) have been commonly seen in palliative surgeries in single ventricle anatomy, no systematic assessment of their impact on patient outcome has been reported. All patients aged 0-17 years admitted to a PICU in a quaternary children's hospital for post-operative management following a primary Fontan procedure between 2005 and 2011 were included. Patients for revision of Fontan or patients admitted to adult Cardiovascular Intensive Care Unit were excluded. Practice policy was changed from routine extubation in the PICU to early extubation in OR in January 2008. Data were compared between the pre-policy-change era (2005-2007) and the post-policy-change era (2008-2011) to assess the impact of the change on patient outcomes. Generalized linear regression (GLM) and interrupted time series (ITS) analysis were used to access the effect of policy change on PICU length of stay and post-operative fluid balance, adjusting for potential confounders using propensity scores. Root cause analysis (RCA) was conducted to describe causes of failed extubation and challenges of this policy change. One hundred twenty-seven children met inclusion criteria. Average body weight was 14.7 kg [standard deviation (SD) 3.9], and age was 3.5 years (SD 1.9). A clear change in extubation practice occurred between the pre- versus post-policy-change eras: 97.5 % were extubated in the PICU in the pre-policy-change era, as compared to 15.0 % in the post-policy-change era. The average PICU length of stay was shortened by 4.1 days from the pre-policy-change era to the post-policy-change era [95 % CI -1.2 to -6.9, p < 0.01] in the GLM, whereas the ITS analysis did not show a statistically significant difference [95 % CI 1.8 to -2.5] (p = 0.23). No statistically significant difference was observed in the fluid balance in the 24 h post-operation in both analyses. Sixteen patients (16/127, 12.6 %) were reintubated mainly for

    Numerous health problems Prison population demographics have dramatically increased during the last thirty years and there is no element that foresees a forthcoming inflection of this tendency. Many studies carried out both in France and elsewhere have assessed the extent of the health problems both on admission to prison and during detention. Difficulties in reducing the risks While available data fully justify the need of a true risk reduction policy, there is an obvious lack of pragmatism and courage in many of the field workers and professionals. Confusion between global prevention, general measures of hygiene and education, and true risk reduction programmes makes the risk reduction policy unclear. The strategy to be adopted All efforts should be dedicated today to make the measures of risk reduction widely available, in particular drug maintenance treatments and condoms, to train prison staff, and to evaluate on a regular basis the clinical practices and their effects. Only a voluntarist and clear health and drug policy, together with a motivated prison staff, including health professional and administration staff, are the keys to success for an efficient risk reduction strategy. It is crucial to implement and to test innovative programs, and to regularly assess all the facets of the risk reduction policy in prisons. PMID:14663377

    Tobacco use is the most important preventable risk factor for premature death. The World Health Organization (WHO) Framework Convention on Tobacco Control (FCTC), the first international public health treaty, came into force in 2005. This paper reviews the present status of tobacco control policies in Korea according to the WHO FCTC recommendations. In Korea, cigarette use is high among adult males (48.2% in 2010), and cigarette prices are the lowest among the Organization for Economic Cooperation and Development countries with no tax increases since 2004. Smoke-free policies have shown incremental progress since 1995, but smoking is still permitted in many indoor public places. More than 30% of non-smoking adults and adolescents are exposed to second-hand smoke. Public education on the harmful effects of tobacco is currently insufficient and the current policies have not been adequately evaluated. There is no comprehensive ban on tobacco advertising, promotion, or sponsorship in Korea. Cigarette packages have text health warnings on only 30% of the main packaging area, and misleading terms such as "mild" and "light" are permitted. There are nationwide smoking cessation clinics and a Quitline service, but cessation services are not covered by public insurance schemes and there are no national treatment guidelines. The sale of tobacco to minors is prohibited by law, but is poorly enforced. The socioeconomic inequality of smoking prevalence has widened, although the government considers inequality reduction to be a national goal. The tobacco control policies in Korea have faltered recently and priority should be given to the development of comprehensive tobacco control policies. PMID:24921015

  19. The National Science Foundation CAREER Award: A Unique Solution to the Challenges of the Tenure Process

    NASA Astrophysics Data System (ADS)

    Fouch, M. J.

    2011-12-01

    There is a dichotomy inherent in the tenure process at most research-strong universities. Most institutions require strong performance in research production and grant acquisition, while at the same time very good to excellent teaching performance. However, in the first several years of the tenure process, many new faculty spend most of their time preparing lectures for new classes and writing grant proposals, leaving little time to forge new directions and define their individual paths in their research, which, somewhat ironically, is the primary factor by which tenure is either granted or denied. The CAREER grant is a unique solution to this problem, as it enables beginning faculty members to directly thread their research into their teaching, and vice versa. My CAREER award, the first granted by the (at the time) fledgling EarthScope Science program at NSF, enabled me to bring EarthScope data and science directly into the classroom. One cadre of efforts was a focus on software development, which is a critical roadblock in geophysics for students who do not have extensive experience with Unix-based coding. For example, Kevin Eagar developed the MATLAB-based FuncLab software system that enables one to quickly and efficiently analyze receiver functions, allowing one to image layers within Earth's interior, such as the crust-mantle boundary. This system is now publically available at http://geophysics.asu.edu/funclab. At Arizona State University, 5 undergraduate students and 2 graduate students have already used this software package to produce publishable scientific results over the past 2 years, enabling them to experience research firsthand and learn a range of key research skills for their future endeavors. The CAREER award also provided ample opportunities for my research group and me to forge into new research directions given the broad scope of the proposed work. Ultimately, this freedom has led to a number of new and exciting results regarding the nature of

    Brazil is the only country in the world to propose a universal health care system with the aim of guaranteeing delivery of all levels of health care, free of charge, to a population of over 200 million inhabitants by means of a unified health system ("Sistema Único de Saúde" [SUS]). The national policy of oral health, also known as Smiling Brazil ("Brasil Sorridente"), was implemented in 2004. Oral health was designated as 1 of the 4 priority areas of the SUS, transforming oral health care in Brazil, with the objective that the SUS achieve the integrality of care envisaged at its creation. The aim of this article is to share part of this experience in order to prompt reflection about the inclusion of oral health care in other health care systems around the world. The most significant results of Smiling Brazil can be seen in 3 areas: (1) oral health epidemiological indicators, (2) financial investment and professional development, and (3) the building of an oral health care network throughout the 10 y of the policy. The "Discovery!" article presented here portrays 10 y of evolution; however, it is important to point out that this is a process undergoing construction and that the oral health care network needs to be further expanded, refined, and solidified so that over time and through changes in the political parties in power, Smiling Brazil prevails as a perennial policy and not merely an action by a single government.

    2010-02-01

    In Germany, smoking rates among women have been slightly declining since 2003. However, smoking rates among young women and girls are high and are reaching the smoking rates of their male counterparts. Only about half of pregnant smokers below the age of 25 stop smoking. Women and girls with low education and low level jobs, those who are unemployed, as well as single parents have the highest smoking rates. The tobacco industry promotes smoking behavior of women and girls through marketing campaigns, thus, systematically counteracting smoking prevention activities. Within the framework of the annual conference 2008 of the Federal Drug Commissioner on the theme of "Women and Smoking", recommendations for a gender-specific tobacco control policy in Germany were developed. The main demands relate to the necessity of a targeted policy approach which takes into account the needs and life circumstances of women and girls, the development of integrated prevention programs for pregnant women, improved medical and preventive care, the involvement of women from the media and culture, from health professions and politics to promote a smoke-free culture, gender-specific research, and the improvement of tobacco control legislation. FACT (Frauen aktiv contra Tabak e.V.) actively supports the implementation of these policy recommendations. PMID:20069267

    2015-01-01

    Infectious diseases have historically resulted in suspended or cancelled military operations. Vaccination for disease prevention is a critical component of the military's force readiness doctrine. Until recently, Korea had not recognized the importance of vaccinating military personnel. However, a 2011 meningococcal disease outbreak at an army recruit training center led to dramatic changes in the paradigm of traditional medical practice in the Korean armed forces. A new vaccination policy was formed by a 2012 Military Healthcare Service Act. Since then, Neisseria meningitidis, hepatitis A, and measles-mumps-rubella vaccines have been routinely administered to all new recruits early in basic training to ensure protection against these diseases. All active-duty soldiers also receive seasonal influenza vaccination annually. Despite quantitative improvements in vaccination policies, several instances of major infectious diseases and adverse vaccine reactions have threatened soldier health. In the future, vaccination policies in the Korean armed forces should be based on epidemiologic data and military medical research for vaccine use and safety management. PMID:25829800

  3. Trade policy and obesity prevention: challenges and innovation in the Pacific Islands.

    PubMed

    Snowdon, W; Thow, A M

    2013-11-01

    The Pacific Island countries experience some of the highest rates of obesity in the world in part due to substantial dietary changes that mirror changes in the food supply in the region. Economic and political ties, donor aid, and trade links are key drivers of the changing availability and accessibility of processed and imported foods. Pacific Island countries have been innovative in developing trade-related policy approaches to create a less obesogenic food environment. Taxation-based approaches that affect pricing in the region include increased import and excise tariffs on sugared beverages and other high-sugar products, monosodium glutamate, and palm oil and lowered tariffs on fruits and vegetables. Other approaches highlight some higher-fat products through labeling and controlling the supply of high-fat meats. The bans on high-fat turkey tails and mutton flaps highlight the politics, trade agreements and donor influences that can be significant barriers to the pursuit of policy options. Countries that are not signatories to trade agreements may have more policy space for innovative action. However, potential effectiveness and practicality require consideration. The health sector's active engagement in the negotiation of trade agreements is a key way to support healthier trade in the region. PMID:24102909

  4. Exposing Coverage Data to the Semantic Web within the MELODIES project: Challenges and Solutions

    Coverage data, typically big in data volume, assigns values to a given set of spatiotemporal positions, together with metadata on how to interpret those values. Existing storage formats like netCDF, HDF and GeoTIFF all have various restrictions that prevent them from being preferred formats for use over the web, especially the semantic web. Factors that are relevant here are the processing complexity, the semantic richness of the metadata, and the ability to request partial information, such as a subset or just the appropriate metadata. Making coverage data available within web browsers opens the door to new ways for working with such data, including new types of visualization and on-the-fly processing. As part of the European project MELODIES (http://melodiesproject.eu) we look into the challenges of exposing such coverage data in an interoperable and web-friendly way, and propose solutions using a host of emerging technologies like JSON-LD, the DCAT and GeoDCAT-AP ontologies, the CoverageJSON format, and new approaches to REST APIs for coverage data. We developed the CoverageJSON format within the MELODIES project as an additional way to expose coverage data to the web, next to having simple rendered images available using standards like OGC's WMS. CoverageJSON partially incorporates JSON-LD but does not encode individual data values as semantic resources, making use of the technology in a practical manner. The development also focused on it being a potential output format for OGC WCS. We will demonstrate how existing netCDF data can be exposed as CoverageJSON resources on the web together with a REST API that allows users to explore the data and run operations such as spatiotemporal subsetting. We will show various use cases from the MELODIES project, including reclassification of a Land Cover dataset client-side within the browser with the ability for the user to influence the reclassification result by making use of the above technologies.

    2015-01-01

    The main challenge of ability tests relates to the difficulty of items, whereas speed tests demand that test takers complete very easy items quickly. This article proposes a conceptual framework to represent how performance depends on both between-person differences in speed and ability and the speed-ability compromise within persons. Related measurement challenges and psychometric models that have been proposed to deal with the challenges are discussed. It is argued that addressing individual differences in the speed-ability trade-off requires the control of item response times. In this way, response behavior can be captured exclusively with the response variable remedying problems in traditional measurement approaches. PMID:26807063

    Introduction The Targeted Subsidies Law (TSL) was implemented in 2010 with a platform of improving equity in the Iran’s society. One of the objectives of the TSL was improving equity in Healthcare Financing (HCF), but a significant change has not occurred since then. The aim of this study was to analyze the challenges of the TSL to equity in the HCF in Iran. Methods In this interpretive qualitative study, 31 policy makers and health system experts were interviewed face to face from September 2014 to June 2015. A purposeful and snowball sampling method was used to select participants. Also, a document analysis was conducted on upstream documents. Assisted by MAXQDA 10, recorded interviews were transcribed verbatim and analyzed based on Framework Approach. Results Content analysis identified two themes and five sub-themes. Lack of justice in the healthcare system and lack of equity in the total socioeconomic structure of Iran were sub-themes identified as barriers to equity in HCF. Shortcomings in the formulation, implementation, and evaluation of the TSL were sub-themes identified as barriers in the policy process. The TSL did not achieve its intended objectives in the health sector because of the above-mentioned barriers, Conclusion The TSL, according to established goals, had no effect on the equity in HCF in Iran because of problems in the structure of the health system, socioeconomic status, and the policy process. To reach a more equitable HCF, it is advised that, when defining the related policies, various barriers be considered, such as those identified in our research. PMID:27053996

  17. Polio immunization policy in the United States: a new challenge for a new generation.

    PubMed Central

    Salk, D

    1988-01-01

    The primary reason that live poliovirus vaccine is recommended in the United States today is because it may immunize contacts who have not otherwise chosen to be vaccinated. This policy places contacts at risk of paralysis from an untested, unlicensed "spread virus" vaccine and places infants at risk for an unproven, theoretical benefit to others, not themselves. The licensed killed poliovirus vaccine provides equivalent protection to those vaccinated, with no risk to recipients or contacts. The preceding analysis by Hinman, et al, is an interesting exercise in modeling, but many of their assumptions are open to question. Their sweeping conclusions are not justified by the type of analysis performed, which should yield an overall assessment of a decision environment not a single optimal choice. No measure of perceived social consequence or patient attitude is included, although this is of central importance today. Their report lends an aura of credibility to one conclusion, but this credibility is illusory at best. The major social issue today is not which vaccine to use, but how should polio immunization policy be evaluated. PMID:3277453

  19. NOA at the Calaveras Dam Replacement Project (CDRP) - Challenges and Solutions

    NASA Astrophysics Data System (ADS)

    Erskine, B.

    2012-12-01

    The San Francisco Public Utilities Commission is one year into construction of the Calaveras Dam Replacement Project (CDRP), a new earthen dam east of Sunol designed to withstand an M 7.1 earthquake on the nearby active Calaveras fault. The zoned earthen dam will be constructed primarily of on-site materials, many of which contain NOA. The upstream shell will be composed of Franciscan complex blueschist which contains crocidolite. This material will be blasted and processed at an on-site quarry. The impermeable core of the dam will be constructed of clay-rich alluvium that contains asbestos derived from Franciscan rocks. This material will be excavated from the south end of the reservoir and transported several miles to the dam. Currently, approximately 3 million yards of Franciscan complex material is being excavated and disposed of within permitted on-site engineered landfills. NOA-bearing rocks that include serpentinite, greenschist, blueschist, and eclogite contain variable amounts and assemblages of chrysotile, actinolite, crocidolite, tremolite, and winchite-class amphiboles. All of these are detected in air samples collected within a sophisticated air monitoring array and analyzed by TEM. The CDRP represents the largest construction project involving NOA in the country. As such, applying regulations that were designed for building materials and routine construction sites, and controlling airborne emissions on such a massive scale, is a major challenge requiring innovative solutions. Because construction occurs simultaneously at distinct and distant parts of the site, and the rugged topography of the site induces complex meteorological conditions, it is sometimes difficult to ascertain the driving activity and location of a source that caused a trigger level exceedance at a perimeter monitoring station. One helpful tool is forensic correlation of source material and air test data using speciation of amphiboles. At the CDRP, we are developing the ability to

    Transcranial direct current stimulation (tDCS), a simple means of brain stimulation, possesses a trifecta of appealing features: it is relatively safe, relatively inexpensive and relatively effective. It is also relatively easy to obtain a device and the do-it-yourself (DIY) community has become galvanised by reports that tDCS can be used as an all-purpose cognitive enhancer. We provide practical recommendations designed to guide balanced discourse, propagate norms of safe use and stimulate dialogue between the DIY community and regulatory authorities. We call on all stakeholders-regulators, scientists and the DIY community-to share in crafting policy proposals that ensure public safety while supporting DIY innovation. PMID:23733050

    2014-01-01

    Public health is increasingly emphasizing policy, systems, and environmental (PSE) change as a key strategy for population-level health promotion and disease prevention. When applied to childhood obesity, this strategy typically involves school systems, since children spend large portions of their days in school and are heavily influenced by this environment. While most school systems have implemented nutrition education and physical activity programs for some time, their understanding and use of PSE approaches to obesity prevention is accelerating based on several large federally funded initiatives. As part of one initiative's evaluation, key informant interviews reveal the specific obesity prevention PSE strategies schools are attempting and the corresponding barriers and facilitators to their implementation. These evaluation findings raise several fundamental issues regarding school-based obesity prevention, including the potential role of school personnel, the influence of grant funding on school health initiatives, and the fit between public health and educational priorities.

    2013-12-01

    The phenomenon of private human access to space has introduced a new set of problems in the insurance sector. Orbital and suborbital space transportation will surely be unique commercial services for this new market. Discussions are under way regarding space insurance, in order to establish whether this new market ought to be regulated by aviation or space law. Alongside new definitions, infrastructures, legal frameworks and liability insurances, the insurance sector has also been introducing a new approach. In this paper, I aim to analyse some of the possibilities of new premiums, capacities, and policies (under aviation or space insurance rules), as well as the new insurance products related to vehicles, passengers and third party liability. This paper claims that a change toward new insurance regimes is crucial, due to the current stage in development of space tourism and the urgency to adapt insurance rules to support future development in this area.

  3. Gun violence and media effects: challenges for science and public policy.

    Elson, Malte; Ferguson, Christopher J

    2013-11-01

    In response to the Sandy Hook shooting in December 2012, the White House published an action plan to reduce gun violence that, among other things, calls for research into the relationship with violence in digital games or other media images. We acknowledge the administration's efforts to reduce violent crime in society and their obligation to dedicate resources to matters of public interest, such as media effects. However, research projects launched in the midst of a moral panic bear the risk of introducing bias and distracting from more important issues. Ideological rigidity has repeatedly shaped past research on media violence. Current initiatives could be an opportunity to restore credibility to the field and to engage in a responsible dialogue on media effects. In order to inform public policy, we need to close gaps, both in empirical research and the academic debate, while being alert for potential political and social influences. PMID:24187065

    Childhood obesity and nutrition are high on the UK policy agenda because of their association with chronic illnesses and related costs. In 2007, to improve children's nutrition, the Government introduced new standards for all school food sources, including products sold from vending machines. Our research explores the factors influencing schools' decisions and children's food choices in relation to vending machines. We conducted in-depth interviews with staff and pupils in one English Local Education Authority. We found that pupils made food decisions based on cost considerations, and convenience, and they strongly valued individual choice. Schools' decisions to provide vending were influenced predominantly by fiscal and structural constraints. Although unhappy with the current quality of school food, staff and pupils criticised initiatives to restrict unhealthy foods. It appears that achieving a healthier school environment is a long-term project involving multiple strategies of education and incentives, as well as regulation. These must involve parents as well as pupils and schools. PMID:20535103

  5. Diabetes in Mexico: cost and management of diabetes and its complications and challenges for health policy

    PubMed Central

    2013-01-01

    Background Mexico has been experiencing some of the most rapid shifts ever recorded in dietary and physical activity patterns leading to obesity. Diabetes mellitus has played a crucial role causing nearly 14% of all deaths. We wanted to make a comprehensive study of the role of diabetes in terms of burden of disease, prevalence, cost of diabetes, cost of complications and health policy. Method We review the quantitative data that provides evidence of the extent to which the Mexican health economy is affected by the disease and its complications. We then discuss the current situation of diabetes in Mexico with experts in the field. Results There was a significant increase in the prevalence of diabetes from 1994 to 2006 with rising direct costs (2006: outpatient USD$ 717,764,787, inpatient USD$ 223,581,099) and indirect costs (2005: USD$ 177,220,390), and rising costs of complications (2010: Retinopathy USD$ 10,323,421; Cardiovascular disease USD$ 12,843,134; Nephropathy USD$ 81,814,501; Neuropathy USD$ 2,760,271; Peripheral vascular disease USD$ 2,042,601). The health policy focused on screening and the creation of self-support groups across the country. Conclusions The increasing diabetes mortality and lack of control among diagnosed patients make quality of treatment a major concern in Mexico. The growing prevalence of childhood and adult obesity and the metabolic syndrome suggest that the situation could be even worse in the coming years. The government has reacted strongly with national actions to address the growing burden posed by diabetes. However our research suggests that the prevalence and mortality of diabetes will continue to rise in the future. PMID:23374611

  6. Deep Vadose Zone Remediation: Technical and Policy Challenges, Opportunities, and Progress in Achieving Cleanup Endpoints

    SciTech Connect

    Wellman, Dawn M.; Freshley, Mark D.; Truex, Michael J.; Lee, Michelle H.

    2013-02-24

    Current requirements for site remediation and closure are standards-based and are often overly conservative, costly, and in some cases, technically impractical. Use of risk-informed alternate endpoints provides a means to achieve remediation goals that are permitted by regulations and are protective of human health and the environment. Alternate endpoints enable the establishment of a path for cleanup that may include intermediate remedial milestones and transition points and/or regulatory alternatives to standards-based remediation. A framework is presented that is centered around developing and refining conceptual models in conjunction with assessing risks and potential endpoints as part of a system-based assessment that integrates site data with scientific understanding of processes that control the distribution and transport of contaminants in the subsurface and pathways to receptors. This system-based assessment and subsequent implementation of the remediation strategy with appropriate monitoring are targeted at providing a holistic approach to addressing risks to human health and the environment. This holistic approach also enables effective predictive analysis of contaminant behavior to provide defensible criteria and data for making long-term decisions. Developing and implementing an alternate endpoint-based approach for remediation and waste site closure presents a number of challenges and opportunities. Categories of these challenges include scientific and technical, regulatory, institutional, and budget and resource allocation issues. Opportunities exist for developing and implementing systems-based approaches with respect to supportive characterization, monitoring, predictive modeling, and remediation approaches.

    SOLUTIONS (2013 to 2018) is a European Union Seventh Framework Programme Project (EU-FP7). The project aims to deliver a conceptual framework to support the evidence-based development of environmental policies with regard to water quality. SOLUTIONS will develop the tools for the identification, prioritisation and assessment of those water contaminants that may pose a risk to ecosystems and human health. To this end, a new generation of chemical and effect-based monitoring tools is developed and integrated with a full set of exposure, effect and risk assessment models. SOLUTIONS attempts to address legacy, present and future contamination by integrating monitoring and modelling based approaches with scenarios on future developments in society, economy and technology and thus in contamination. The project follows a solutions-oriented approach by addressing major problems of water and chemicals management and by assessing abatement options. SOLUTIONS takes advantage of the access to the infrastructure necessary to investigate the large basins of the Danube and Rhine as well as relevant Mediterranean basins as case studies, and puts major efforts on stakeholder dialogue and support. Particularly, the EU Water Framework Directive (WFD) Common Implementation Strategy (CIS) working groups, International River Commissions, and water works associations are directly supported with consistent guidance for the early detection, identification, prioritisation, and abatement of chemicals in the water cycle. SOLUTIONS will give a specific emphasis on concepts and tools for the impact and risk assessment of complex mixtures of emerging pollutants, their metabolites and transformation products. Analytical and effect-based screening tools will be applied together with ecological assessment tools for the identification of toxicants and their impacts. The SOLUTIONS approach is expected to provide transparent and evidence-based candidates or River Basin Specific Pollutants in the case

    In Vietnam, the WHO Framework Convention on Tobacco Control (WHO FCTC) took effect in March 2005 while MPOWER has been implemented since 2008. This paper describes the progress and challenges of implementation of the MPOWER package in Vietnam. We can report that, in term of monitoring, Vietnam is very active in the Global Tobacco Surveillance System, completing two rounds of the Global Adult Tobacco Survey (GATS) and three rounds of the Global Youth Tobacco Survey (GYTS). To protect people from tobacco smoke, Vietnam has issued and enforced a law requiring comprehensive smoking bans at workplaces and public places since 2013. Tobacco advertising and promotion are also prohibited with the exception of points of sale displays of tobacco products. Violations come in the form of promotion girls, corporate social responsibility activities from tobacco manufacturers and packages displayed by retail vendors. Vietnam is one of the 77 countries that require pictorial health warnings to be printed on cigarette packages to warn about the danger of tobacco and the warnings have been implemented effectively. Cigarette tax is 70% of factory price which is equal to less than 45% of retail price and much lower than the recommendation of WHO. However, Vietnam is one of the very few countries that require manufacturers and importers to make "compulsory contributions" at 1-2% of the factory price of cigarettes sold in Vietnam for the establishment of a Tobacco Control Fund (TCF). The TCF is being operated well. In 2015, 67 units of 63 provinces/cities, 22 ministries and political-social organizations and 6 hospitals received funding from TCF to implement a wide range of tobacco control activities. Cessation services have been starting with a a toll-free quit-line but need to be further strengthened. In conclusion, Vietnam has constantly put efforts into the tobacco control field with high commitment from the government, scientists and activists. Though several remarkable achievements

  10. Diabetes in Argentina: cost and management of diabetes and its complications and challenges for health policy

    PubMed Central

    2013-01-01

    Background Diabetes is an expensive disease in Argentina as well as worldwide, and its prevalence is continuously rising affecting the quality of life of people with the disease and their life expectancy. It also imposes a heavy burden to the national health care budget and on the economy in the form of productivity losses. Aims To review and discuss a) the reported evidence on diabetes prevalence, the degree of control, the cost of care and outcomes, b) available strategies to decrease the health and economic disease burden, and c) how the disease fits in the Argentinian health care system and policy. Finally, to propose evidence-based policy options to reduce the burden of diabetes, both from an epidemiological as well as an economic perspective, on the Argentinian society. The evidence presented is expected to help the local authorities to develop and implement effective diabetes care programmes. Methodology A comprehensive literature review was performed using databases such as MEDLINE, EMBASE and LILACS (Latin American and Caribbean Health Sciences). Literature published from 1980 to 2011 was included. This information was complemented with grey literature, including data from national and provincial official sources, personal communications and contacts with health authorities and diabetes experts in Argentina. Results Overall diabetes prevalence increased from 8.4% in 2005 to 9.6% 2009 at national level. In 2009, diabetes was the seventh leading cause of death with a mortality rate of 19.2 per 100,000 inhabitants, and it accounted for 1,328,802 DALYs lost in the adult population, mainly affecting women aged over fifty. The per capita hospitalisation cost for people with diabetes was significantly higher than for people without the disease, US$ 1,628 vs. US$ 833 in 2004. Evidence shows that implementation of combined educative interventions improved quality of care and outcomes, decreased treatment costs and optimised the use of economic resources

    Access to the right to the highest attainable level of health is a constitutional right that obliges governments and other players to take step to increase all individuals' chances of obtaining good health. At the least, health and education are two crucial requirements for this as well. Iran's vision 2025 is going to lead the country to a developed state with the highest rank of economic, scientific and technological status in the region. Enjoying health, welfare, food security, social security, equal opportunities, etc, are also considered as part of characteristics of Iranian society in 2025. Although health system of Iran has many achievements in providing health services specially for the poor following the Islamic Revolution of 1979, but the evidences gathered to develop the 5(th) 5-years economical, social and cultural plan (5(th)5YDP:2011-2015), listed a variety of main challenges in stewardship, financing, resources generation and service provision functions of the existing health system. Thus, to overcome the main challenges, about 11% of general policies of 5(th)5YDP are directly address health related issues with emphasizing on healthy human and comprehensive health approach with considering: Integration of policy making, planning, evaluation, supervision and public financing; Developing both quantity and quality of health insurance system and reducing out-of-pocket expenditures for health services to 30% by the end of the 5th plan. The strategies of 5(th)5YDP adopted by the parliament as an Act will change the health system fundamentally through tuning the main drivers; so, its implementation needs brave leaders, capable managers, motivated technical staff and social mobilization.

    The need for health services research is likely to rise rapidly as the population ages, health care costs soar, and therapeutic and diagnostic choices proliferate. Building an effective and efficient health care delivery system is a national priority. Yet the national health care quality report concludes that we lack the ability to monitor progress toward even basic quality and patient safety goals effectively. The gap between the need to improve and our ability to do so exists in part because we fail to view the delivery of health care as science, we lack national improvement priorities, and we lack a national infrastructure to achieve our stated goals. We discuss key challenges implicit in correcting these failures and recommend actions to expedite progress. PMID:21054369

    1992-01-01

    As political pressure for affordable universal coverage intensifies, various proposals have been crafted to improve the system without sacrificing the role of the private sector. Some analysts view the preservation of a mixed public-private system as an exercise in incrementalism, avoiding disquieting departures from familiar arrangements. A review of the political and administrative challenges of several main options--market innovation, tax credits, play or pay, and Medicaid expansion--suggests that the path to true reform is a slippery slope. Over time, changes in particular sectors, such as insurance, employers, government, and providers, will very likely implicate the others too. Although redefining the public-private mix may be more incremental than (say) adoption of a Canadian model, it will also entail considerable "creative destruction" of existing patterns and cannot fail to disturb the institutional status quo substantially.

    Deep vadose zone contamination is a significant issue facing the U.S. Department of Energy’s (DOE) Office of Environmental Management (EM). Contamination in the deep vadose zone is isolated from exposure such that direct contact is not a factor in risk to human health and the environment; rather, movement of contamination from the deep vadose zone to the groundwater creates the potential for exposure and risk to receptors. Transport of deep vadose zone contamination and discharge to the groundwater creates the potential for exposure and risk to receptors, so limiting flux to groundwater is key for protection of groundwater resources. Remediation approaches for the deep vadose zone need to be considered within the regulatory context, targeted at mitigating the source of contamination and reduce contaminant flux to groundwater. This paper reviews the processes for deep vadose zone metal and radionuclide remediation as well as challenges and opportunities for implementation.

  15. Enhancing the role of geodiversity and geoheritage in environmental management and policy in a changing world: challenges for geoscience research

    2013-04-01

    Geodiversity delivers or underpins many key ecosystem processes and services that deliver valuable benefits for society. With a growing recognition of the wider economic, social and environmental relevance of geodiversity, it is timely to consider the research requirements and priorities that are necessary to underpin a broader interdisciplinary approach to geodiversity that incorporates the links between natural and human systems in a changing world. A key challenge is to develop the scientific framework of geodiversity and at the same time to enhance the protection of geoheritage. Research that helps to support environmental policy and meet the wider needs of society for sustainable development and improved human wellbeing is fundamental both to improve the recognition of geodiversity and to demonstrate the wider relevance and value of geoheritage and geoconservation. Within this wider context, priorities for research include: 1) assessment of geoheritage and best-practice management of geosites for multiple uses including science, education and tourism; 2) evaluation of geodiversity and the ecosystem services it provides, both in economic and non-economic terms, to help build policy support and public awareness; 3) understanding the functional links between geodiversity and biodiversity across a range of spatial and temporal scales to help assess ecosystem sensitivity and inform management adaptations to climate change, particularly in dynamic environments such as the coast, river catchments and mountain areas; 4) providing a longer time perspective on ecosystem trends and services from palaeoenvironmental records; 5) applications of geodiversity in terrestrial and marine spatial planning.

    The need for parenting and relationship strengthening programs is important among low-income minority parents where the burden of relational and parental stressors contributes to relationship dissolution. We examine these stressors among young parents. Data were collected from four focus groups (N = 35) with young parents. Data were audio-recorded and transcribed. Inductive coding was used to generate themes and codes, and analysis was completed using NVivo. Relationship and parenting challenges, values, and areas of need were the three major themes that emerged. Women's relationship challenges were family interference and unbalanced parenting, and men reported feeling disrespected and having limited finances. Common relationship challenges for women and men were family interference and unbalanced parenting. Both genders valued trust, communication, and honesty in relationships. Areas of need for women and men included: improving communication and understanding the impact of negative relationships on current relationships. Parenting challenges for women were unbalanced parenting, child safety, and feeling unprepared to parent; men reported limited finances. Both genders valued quality time with child to instill family morals. Areas of need for women and men included learning child discipline techniques and increasing knowledge about child development. Finally, women and men have relationship and parenting similarities and differences. Young parents are interested in learning how to improve relationships and co-parent to reduce relationship distress, which could reduce risk behaviors and improve child outcomes. PMID:24980026

    1982-11-01

    Data reported by skilled nursing facilities (SNFs) in an eight-county area in Northern California for 1977-78 indicate that the typical SNF resident was a impoverished female who was at least 75 years old. Her SNF stay was subsidized by MediCal, California's Medicaid program. She was in an urban, for-profit SNF for at least one year, during which time approximately one quarter of her co-residents died. She received about 2 hours of daily side-orderly-attendant care and almost 45 minutes of licensed nurse care. Although her most frequent contact was with aides-orderlies-attendants, a sustained relationship with the staff was not likely because of high employee turnover rate in the facility. This resident had a one-in-three chance of being in a SNF that had been cited (though the citation had not necessarily been upheld) for poor to life-threatening care. This information underscores the urgency of reorienting public policies so that they are based on the needs of the chronically ill elderly. Such a reorientation would I) ensure that people receive professional and paraprofessional services in the least restrictive environment; 2) preclude criticism of nursing homes for "warehousing" the elderly when there is actually little choice in the matter; and 3) enable the nation's elderly to live out their lives with sense of self-worth and dignity, and with the knowledge that they are valued members of society.

    2015-04-01

    Providing energy for the contemporary world has resulted in a multi-variable problem in which a confluence of historical anomalies and economic, psychological, political, and demographic factors thwart efforts to prevent significant harm from increasing atmospheric CO2. This unlikely combination has created the perfect storm in which the warnings by scientists are ineffective. Global warming is occurring simultaneously with increased population, some dysfunctional political institutions, ascendency of oversimplified economic theory, campaigns to discredit scientists, misinterpretation of the meaning of noise in the Milankovitch climate cycles, and substantially improved hydrocarbon extraction methods. These factors are compounded by traits of human nature, such as greed and resistance to changing the familiar and discontinuing profitable endeavors. The idea that future people are equal with us may not be widely supported, yet this value is the foundation of climate change action. History shows that most people and nations will not take appropriate measures until forced, yet the cost increases as action is delayed. This makes appropriate policies even more extreme and difficult to accomplish as more wealth is consumed in treating global warming symptoms.

    Four formal rounds of Trans-Pacific Partnership Agreement (TPPA) negotiations took place in 2010. They involved over 200 officials from Australia, the United States, New Zealand, Chile, Singapore, Brunei, Peru, Vietnam and Malaysia. Future negotiations officially are set to include three issues with public health and medicines policy implications for Australia and our region: ways to approach regulatory coherence and transparency; how to benefit multinational and small-medium enterprises; and multilateral investor-state dispute settlement. US-based multinational pharmaceutical companies are lobbying for TPPA provisions like those in the Australia-US Free Trade Agreement, which reduce government cost-effectiveness regulatory control of pharmaceuticals, threatening equitable access to medicines. They also advocate increased TPPA intellectual monopoly privilege protection, which will further limit the development of Australian generic medicine enterprises and restrict patient access to cheap, bioequivalent prescription drugs. Of particular concern is that proposed TPPA multilateral investor-state dispute settlement procedures would allow US corporations (as well as those of other TPPA nations) to obtain damages against Australian governments through international arbitral proceedings if their investments are impeded by Australian public health and environment protection legislation.

    The Caribbean region presents the highest prevalence of HIV/AIDS worldwide after sub-Saharan Africa; leading to serious social, economic and health consequences at the local scale but also at the regional and global levels. In Colombia, a national plan to tackle the epidemic was formulated with little evidence that its implementation in the local context is effective. This study focused on Cartagena - one of Colombia's largest cities and an international touristic hub - that presents one of the highest HIV prevalences in the country, to investigate whether the national plan accounts for local specificities and what are the barriers to local implementation. Based on the Contextual Interaction Theory (CIT), this qualitative research relied upon 27 interviews and 13 life stories of local inhabitants and stakeholders, collected in a first fieldwork in 2006-2007. A follow-up data collection took place in 2013 with 10 participants: key policymakers and implementers, NGO representatives and local inhabitants. Barriers identified by the participants included: local population's understandings and beliefs on condom use; stigma and discrimination; lack of collaboration from the Church, the education sector and local politicians; corruption; high staff turnover; frequent changes in leadership; lack of economic and human resources; and barriers to health care access. The findings suggest that global influences also have an impact on the CIT framework (e.g. international organisations as a major financier in HIV prevention). The participants put forward several feasible solutions to implementation barriers. We discuss how several of the proposed solutions have been applied in other Latin American and Caribbean countries and yielded positive results. However, further research is needed to find possible ways of overcoming certain barriers identified by this study such as corruption, the lack of collaboration of the Church and barriers to health care access.

    Antarctica is a unique and geographically remote environment. Traditional field campaigns investigating geology and vegetation in the region encounter numerous challenges including the harsh polar climate, the invasive nature of the work, steep topography and high infrastructure costs. Additionally, such field campaigns are often limited in terms of spatial and temporal resolution, and particularly, the topographical challenges presented in the Antarctic mean that many areas remain inaccessible. Remote Sensing, particularly hyperspectral imaging, may provide a solution to overcome the difficulties associated with field based mapping in the Antarctic. Planned satellite launches, such as EnMAP and HyspIRI, if successful, will yield large-scale, repeated hyperspectral imagery of Antarctica. Hyperspectral imagery has proven mapping capabilities and can yield greater information than can be attained using multispectral data. As a precursor to future satellite imagery, we utilise hyperspectral imagery from the first known airborne hyperspectral survey carried out in the Antarctic by the British Antarctic Survey and partners in 2011. Multiple imaging spectrometers were simultaneously deployed covering the visible, shortwave and thermal infrared regions of the electromagnetic spectrum. Additional data was generated during a field campaign deploying multiple ground spectrometers covering the same wavelengths as the airborne imagers. We utilise this imagery to assess the current challenges and propose some new solutions for mapping vegetation and geology, which may be directly applicable to future satellite hyperspectral imagery in the Antarctic.

    Family interventions for schizophrenia have been amply demonstrated to be effective and are recommended by most of the international clinical guidelines. However, their implementation in the clinical setting as well as in treatment protocols of patients with psychosis has not been fully achieved yet. With the increasing deinstitutionalization of patients, family has begun to assume the role of care performed by psychiatric hospitals, with a high emotional cost for caregivers as well as the recognition of burden experiences. Families have been the substitute in the face of the scarcity of therapeutic, occupational, and residential resources. For this reason, the viability of patients’ care by their families has become a challenge. This article aims to discuss the most important aspects of family interventions, their impact on families, and the most important challenges that need to be overcome in order to achieve well-being and recovery in both patients and caregivers.

    2014-12-01

    We discuss a range of Bayesian modelling approaches for spatial data and investigate some of the associated computational challenges. This paper commences with a brief review of Bayesian mixture models and Markov random fields, with enabling computational algorithms including Markov chain Monte Carlo (MCMC) and integrated nested Laplace approximation (INLA). Following this, we focus on the Potts model as a canonical approach, and discuss the challenge of estimating the inverse temperature parameter that controls the degree of spatial smoothing. We compare three approaches to addressing the doubly intractable nature of the likelihood, namely pseudo-likelihood, path sampling and the exchange algorithm. These techniques are applied to satellite data used to analyse water quality in the Great Barrier Reef.

    Protein-protein interaction is of primary importance to understand protein functions. In recent years, the high-throughput AP-MS experiments have generated a large amount of bait-prey data, posing great challenges on the computational analysis of such data for inferring true interactions and protein complexes. To date, many research efforts have been devoted to developing novel computational methods to analyze these AP-MS data sets. In this article, we review and classify the key computational methods developed for the inference of protein-protein interactions and the detection of protein complexes from the AP-MS experiments. We hope that our review as well as the challenges highlighted in the article will provide valuable insights into driving future research for further advancing the state-of-the-art technologies in computational prediction, characterization and analysis of protein-protein interactions and protein complexes from the AP-MS data.

    Fatigue crack growth analysis software has been available to damage tolerance analysts for many years in either commercial products or via proprietary in-house codes. The NASGRO software has been publicly available since the mid-80s (known as NASA/FLAGRO up to 1999) and since 2000 has been sustained and further developed by a collaborative effort between Southwest Research Institute® (SwRI®), the NASA Johnson Space Center (JSC), and the members of the NASGRO Industrial Consortium. Since the stress intensity factor (K) is the foundation of fracture mechanics and damage tolerance analysis of aircraft structures, a significant focus of development efforts in the past fifteen years has been geared towards enhancing legacy K solutions and developing new and efficient numerical K solutions that can handle the complicated stress gradients computed by today’s analysts using detailed finite element models of fatigue critical locations. This paper provides an overview of K solutions that have been recently implemented or improved for the analysis of geometries such as two unequal through cracks at a hole and two unequal corner cracks at a hole, as well as state-of-the-art weight function models capable of computing K in the presence of univariant and/or bivariant stress gradients and complicated residual stress distributions. Some historical background is provided to review how common K solutions have evolved over the years, including selective examples from the literature and from new research. Challenges and progress in rectifying discrepancies between older legacy solutions and newer models are reviewed as well as approaches and challenges for verification and validation of K solutions. Finally, a summary of current challenges and future research and development needs is presented. A key theme throughout the presentation of this paper will be how members of the aerospace industry have collaborated with software developers to develop a practical analysis tool that is

    Complex regional pain syndrome has long been recognized as a severe and high impact chronic pain disorder. However, the condition has historically been difficult to define and classify and little attention has been given to where complex regional pain syndrome sits within other apparently similar chronic pain disorders, such as fibromyalgia and regional pain syndrome. In this review challenges in regard to nomenclature, definitions, and classification of complex regional pain syndrome are reviewed and suggestions are provided about future directions.

    2015-12-01

    The main objective of this study was to explore the perception and understanding of economic, legal, and social barriers that may restrain generic uptake among recognized international experts in health care, and to identify and verify recommendations on how to streamline generic substitution (GS) at no expense of therapeutic safety. A questionnaire survey was devised, and experts with world-renowned expertise in the field of generic medicinal products were selected. Almost 3/4 of respondents claimed that all drugs that satisfy bioequivalence criteria represent similar efficacy and adverse effects, and 1/4 of respondents believed that some differences could be reported. The majority of experts supported (i) the right of patients to refuse GS, (ii) the right of physicians to veto GS, and (iii) the introduction of a statutory obligation to provide patients with access to the cheapest generics available on the market. The main obstacles to more general uptake of generics were as follows: (i) perception of generics as lower quality products, (ii) absence of a transparent policy governing GS, and (iii) disincentives to pharmacists and physicians. Among the most popular recommendations were as follows: (i) introduction of various measures to aid physicians in generic prescribing, (ii) setting clear guidelines specifying when GS is not advisable, (iii) supporting competition on the generic market. The views of experts and the resulting recommendations were strongly affected by their opinion on the bioequivalence of generics. From this analysis, we have selected several principal recommendations which could help shape successful healthcare policies regarding GS. PMID:26214281

    Circulating tumor cells (CTCs) are very attractive surrogate markers for systemic cancer. Currently, major efforts are being made to use these rare cells in the sense of a liquid biopsy to gain molecular information for rational therapeutic decision-making. The advancements in molecular analyses of CTCs down to the single-cell level have been significant in recent years and some applications are ready to be used in clinical studies. As discussed in this review, a major challenge for translating such molecular CTC-based assays into the clinic is the extremely low frequency of CTCs and the associated problems of their reliable detection and isolation. A potential solution to overcome the low CTC frequency is the recently introduced diagnostic leukapheresis that permits screening of liters of blood. Discussed here are the challenges as well as the current efforts implementing this method into clinical workflows to realize more reliable liquid biopsies. PMID:26587751

    2009-01-01

    Marine biofouling is of major economic concern to all marine industries. The shipping trade is particularly alert to the development of new antifouling (AF) strategies, especially green AF paint as international regulations regarding the environmental impact of the compounds actually incorporated into the formulations are becoming more and more strict. It is also recognised that vessels play an extensive role in invasive species propagation as ballast waters transport potentially threatening larvae. It is then crucial to develop new AF solutions combining advances in marine chemistry and topography, in addition to a knowledge of marine biofoulers, with respect to the marine environment. This review presents the recent research progress made in the field of new non-toxic AF solutions (new microtexturing of surfaces, foul-release coatings, and with a special emphasis on marine natural antifoulants) as well as the perspectives for future research directions.

    The failure of the standard Growth Approach to economic development to solve the problems of underdevelopment in LDCs has caused an alternative approach, Basic Needs Approach (BNA), to attain prominence in development thought. BNA emphasizes poverty-minimizing growth. Its strategy of direct attack on poverty has better potential for LDCs' development and fulfillment of their populations' basic needs than the trickle-down mechanism of the Growth Approach. BNA requires, among other things, (a) suitable rural financial markets (RFMs) as parts of the overall financial system, and (b) indigenous technological capabilities. The financial system, if it functions as a central element in an institutionalized technology policy, can link technology-related institutions that generate, evaluate, and promote appropriate technologies (ATs) with RFMs that can support adoption and diffusion of ATs in the agro-rural sector. The above argument uses Bangladesh as a case for illustration. In the light of an institutional framework presented, examined, and extended in this dissertation, it is found that Bangladesh currently does not have an institutionalized technology policy. The current organizational framework and policies related to technological development are not conducive to BNA.

    The World Health Organization estimates that, in 2012, there were 1,589,925 deaths from lung cancer worldwide. Screening for lung cancer with low-dose computed tomography (LDCT) has the potential to significantly alter this statistic, by identifying lung cancers in earlier stages, enabling curative treatment. Challenges remain, however, in replicating the 20% mortality benefit demonstrated by the National Lung Screening Trial (NLST), in populations outside the confines of a research trial, not only in the US but around the world. We review the history of lung cancer screening, the current evidence for LDCT screening, and the key elements needed for a successful screening program. PMID:26380176

  7. Recruitment using mobile telephones in an Irish general population sexual health survey: challenges and practical solutions

    PubMed Central

    2012-01-01

    Background Non-coverage of households without a landline telephone is a major concern of telephone survey researchers. Sampling mobile telephone users in national surveys is vital in order to gain access to the growing proportion of households that use mobile telephones extensively or exclusively. The complex logistics of conducting surveys with mobile telephones have been discussed in the literature. This paper outlines the actual challenges encountered during a recent national sexual health survey in Ireland, which utilized a mobile telephone sampling frame to recruit approximately half of the sample. Method The 2010 Irish Contraception and Crisis Pregnancy Survey (ICCP-2010) is a nationally representative sample of adults aged 18-45 years living in Ireland (n = 3002; 1416 recruited by landline telephone and 1586 recruited by mobile telephone). The overall response rate for the survey was 69% (79% for the landline telephone strand; 61% for the mobile telephone strand). All interviews were conducted using computer-assisting telephone interviewing. Results During the 18-week fieldwork period, five main challenges relating to the use of mobile telephones were encountered: (1) explaining to respondents how random digit dialling works in relation to mobile telephones; (2) establishing the respondent's eligibility; (3) calling the respondent with the Caller ID blocked or withheld; (4) calling the respondent when they are in any number of locations or situations; and (5) explaining to respondents the importance of refusal conversion calls for the response rate calculation. Details of how the survey protocols and procedures were monitored and adapted throughout the study to ensure a high response rate are outlined. Conclusion It is undeniably more challenging to recruit respondents using mobile telephones as opposed to landline telephones. Respondents are generally not familiar with being contacted on their personal mobile telephone for the purposes of being recruited

    2015-10-01

    Accurate quantification of the chemical composition of eudialyte group minerals (EGM) with the electron probe microanalyzer is complicated by both mineralogical and X-ray-specific challenges. These include structural and chemical variability, mutual interferences of X-ray lines, in particular of the rare earth elements, diffusive volatility of light anions and cations, and instability of EGM under the electron beam. A novel analytical approach has been developed to overcome these analytical challenges. The effect of diffusive volatility and beam damage is shown to be minimal when a square of 20×20 µm is scanned with a beam diameter of 6 µm at the fastest possible speed, while measuring elements critical to electron beam exposure early in the measurement sequence. Appropriate reference materials are selected for calibration considering their volatile content and composition, and supplementary offline overlap correction is performed using individual calibration factors. Preliminary results indicate good agreement with data from laser ablation inductively coupled plasma mass spectrometry demonstrating that a quantitative mineral chemical analysis of EGM by electron probe microanalysis is possible once all the parameters mentioned above are accounted for.

    The ALMA radio-telescope, currently under construction in northern Chile, is a very advanced instrument that presents numerous challenges. From a software perspective, one critical issue is the design of graphical user interfaces for operations monitoring and control that scale to the complexity of the system and to the massive amounts of data users are faced with. Early experience operating the telescope with only a few antennas has shown that conventional user interface technologies are not adequate in this context. They consume too much screen real-estate, require many unnecessary interactions to access relevant information, and fail to provide operators and astronomers with a clear mental map of the instrument. They increase extraneous cognitive load, impeding tasks that call for quick diagnosis and action. To address this challenge, the ALMA software division adopted a user-centered design approach. For the last two years, astronomers, operators, software engineers and human-computer interaction researchers have been involved in participatory design workshops, with the aim of designing better user interfaces based on state-of-the-art visualization techniques. This paper describes the process that led to the development of those interface components and to a proposal for the science and operations console setup: brainstorming sessions, rapid prototyping, joint implementation work involving software engineers and human-computer interaction researchers, feedback collection from a broader range of users, further iterations and testing.

    2015-12-01

    Academic medical centers (AMCs) and universities are experiencing increasing pressure to enhance the value they offer at the same time that they are facing challenges related to outcomes, controlling costs, new competition, and government mandates. Yet, rarely do the leaders of these academic neighbors work cooperatively to enhance value. In this Perspective the author, a former university regional campus president with duties in an AMC as an academic physician, shares his insights into the shared challenges these academic neighbors face in improving the value of their services in complex environments. He describes the successes some AMCs have had in generating revenues from new clinical programs that reduce the overall cost of care for larger populations. He also describes how several universities have taken a comprehensive approach to reduce overhead and administrative costs. The author identifies six themes related to successful value improvement efforts and provides examples of successful strategies used by AMCs and their university neighbors to improve the overall value of their programs. He concludes by encouraging leaders of AMCs and universities to share information about their successes in value improvements with each other, to seek additional joint value enhancement efforts, and to market their value improvements to the public.

    The Northern Territory of Australia is a vast area serviced by two major tertiary hospitals. It has both a unique demography and geography, which pose challenges for delivering optimal heart failure services. The prevalence of congestive heart failure continues to increase, imposing a significant burden on health infrastructure and health care costs. Specific patient groups suffer disproportionately from increased disease severity or service related issues often represented as a "health care gap". The syndrome itself is characterised by ongoing symptoms interspersed with acute decompensation requiring lifelong therapy and is rarely reversible. For the individual client the overwhelming attention to heart failure care and the impact of health care gaps can be devastating. This gap may also contribute to widening socio-economic differentials for families and communities as they seek to take on some of the care responsibilities. This review explores the challenges of heart failure best practice in the Northern Territory and the opportunities to improve on service delivery. The discussions highlighted could have implications for health service delivery throughout regional centres in Australia and health systems in other countries. PMID:24548637

    Purpose of review In contrast to many other human diseases, the use of genome-wide association studies (GWAS) to identify genes for heart failure (HF) has had limited success. We will discuss the underlying challenges as well as potential new approaches to understanding the genetics of common forms of HF. Recent findings Recent research using intermediate phenotypes, more detailed and quantitative stratification of HF symptoms, founder populations and novel animal models has begun to allow researchers to make headway toward explaining the genetics underlying HF using GWAS techniques. Summary By expanding analyses of HF to improved clinical traits, additional HF classifications and innovative model systems, the intractability of human HF GWAS should be ameliorated significantly.

    Purpose A number of key issues related to employment of persons with disabilities demand ongoing and effective lines of inquiry. There is evidence, however, that work researchers struggle with recruitment of participants, and that this may limit the types and appropriateness of methods selected. This two phase study sought to identify the nature of recruitment challenges in workplace-based disability research, and to identify strategies for addressing identified barriers. Methods The first phase of this study was a scoping review of the literature to identify the study designs and approaches frequently used in this field of inquiry, and the success of the various recruitment methods in use. In the second phase, we used qualitative methods to explore with employers and other stakeholders in the field their perceived challenges related to participating in disability-related research, and approaches that might address these. Results The most frequently used recruitment methods identified in the literature were non-probability approaches for qualitative studies, and sampling from existing worker databases for survey research. Struggles in participant recruitment were evidenced by the use of multiple recruitment strategies, and heavy reliance on convenience sampling. Employers cited a number of barriers to participation, including time pressures, fear of legal reprisal, and perceived lack of relevance to the organization. Conclusions Participant recruitment in disability-related research is a concern, particularly in studies that require collection of new data from organizations and individuals, and where large probability samples and/or stratified or purposeful samples are desirable. A number of strategies may contribute to improved success, including development of participatory research models that will enhance benefits and perceived benefits of workplace involvement.

    2013-12-01

    PolarTREC (Teachers and Researchers Exploring and Collaborating) is a program in which K-12 teachers spend 2-6 weeks participating in hands-on field research experiences in the polar regions. The goal of PolarTREC is to invigorate polar science education and understanding by bringing K-12 educators and polar researchers together. Program data has illuminated a crucial dynamic that increases the potential for a successful climate change science campaign. We contend that the inclusion of a teacher into the field research campaign can tackle challenges such as reframing climate change science to better address the need for a particular campaign, as well as garnering the science project the necessary support through effective, authentic, and tangible communication efforts to policymakers, funders, students, and the public. The program evaluation queried researchers on a.) the teachers' primary roles in the field b.) the impact teachers on the team's field research, and c.) the teachers' role conducting outreach. Additionally, researchers identified the importance of the facilitator, the Arctic Research Consortium of the United States (ARCUS), as an integral component to the challenge of providing a meaningful broader impact statement to the science proposal. Researchers reported the value of explaining their science, in-situ, allowed them to reframe and rework the objectives of the science project to attain meaningful outcomes. More than half of the researchers specifically noted that one of the strengths of the PolarTREC project is its benefit to the scientific process. The researchers also viewed PolarTREC as an essential outreach activity for their research project. Other researchers said that the outreach provided by their teacher also improved the research project's public image and articulated complex ideas to the public at large. This presentation will speak to the practices within the PolarTREC program and how researchers can meet outreach expectations, impact

    PARTICLE_RISK was one of the first multidisciplinary projects funded by the European Commission's Framework Programme that was responsible for evaluating the implications of nanomaterial (NM) exposure on human health. This project was the basis for this review which identifies the challenges that exist within the assessment of NM risk. We have retrospectively reflected on the findings of completed nanotoxicology studies to consider what progress and advances have been made within the risk assessment of NMs, as well as discussing the direction that nanotoxicology research is taking and identifying the limitations and failings of existing research. We have reflected on what commonly encountered challenges exist and explored how these issues may be resolved. In particular, the following is discussed (i) NM selection (ii) NM physico-chemical characterisation; (iii) NM dispersion; (iv) selection of relevant doses and concentrations; (v) identification of relevant models, target sites and endpoints; (vi) development of alternatives to animal testing; and (vii) NM risk assessment. These knowledge gaps are relatively well recognised by the scientific community and recommendations as to how they may be overcome in the future are provided. It is hoped that this will help develop better defined hypothesis driven research in the future that will enable comprehensive risk assessments to be conducted for NMs. Importantly, the nanotoxicology community has responded and adapted to advances in knowledge over recent years to improve the approaches used to assess NM hazard, exposure and risk. It is vital to learn from existing information provided by ongoing or completed studies to avoid unnecessary duplication of effort, and to offer guidance on aspects of the experimental design that should be carefully considered prior to the start of a new study.

  3. Ethnic-Racial Stigma and Health Disparities: From Psychological Theory and Evidence to Public Policy Solutions

    2014-01-01

    The presence of diverse ethnic-racial groups in the United States today is a source of national pride. However, this cultural sentiment is overshadowed by the reality that those ethnic-racial groups that are stigmatized carry a disproportionate burden of negative physical health outcomes. These systematic differences are referred to as health disparities. Although this phenomenon is fairly well documented, relatively little is understood about the social contexts and the psychological processes they activate that contribute to poor health. More importantly, to demonstrate the processes underlying health disparities does not single-handedly address the issue of social injustice in the health of disadvantaged people. Scientists must assume the burden of facilitating the translation of their laboratory and community-based research to public policy recommendations. This volume of the Journal of Social Issues brings together social, developmental, cognitive, and clinical psychological research on the physical health of ethnic-racial stigmatized individuals in the United States. Each contribution explicitly discusses the implications of research for public health policy. PMID:25530632

    In the area of energy efficiency, advanced technologies combined with best practices appear to afford not only large, but also cost-effective options to conserve energy and reduce greenhouse gas emissions (McKinsey & Company, 2007). In practice, however, the realization of this potential has often proven difficult. Progress appears to require large numbers of individuals to act knowledgeably, and each individual must often act with enabling assistance from others. Even when consumer education is effective and social norms are supportive, the actions of individuals and businesses can be impeded by a broad range of barriers, many of which are non-technical in nature. Title XVI of the Energy Policy Act of 2005 included a mandate to examine barriers to progress and make recommendations in this regard. A detailed report on barriers as well as the National strategy for overcoming barriers met this requirement (Brown et al, 2008; CCCSTI, 2009). Following up on this mandate, the U.S. Climate Change Technology Program (CCTP) chose to focus next on the development of policy options to improve energy efficiency in residential buildings, with supporting analysis of pros and cons, informed in part by behavioral research. While this work is sponsored by CCTP, it has been undertaken in coordination with DOE's Building Technologies Program and Office of Electricity Delivery and Energy Reliability.

    Combining macromolecular crystallography with in crystallo micro-spectrophotometry yields valuable complementary information on the sample, including the redox states of metal cofactors, the identification of bound ligands and the onset and strength of undesired photochemistry, also known as radiation damage. However, the analysis and processing of the resulting data differs significantly from the approaches used for solution spectrophotometric data. The varying size and shape of the sample, together with the suboptimal sample environment, the lack of proper reference signals and the general influence of the X-ray beam on the sample have to be considered and carefully corrected for. In the present article, how to characterize and treat these sample-dependent artefacts in a reproducible manner is discussed and the SLS-APE in situ, in crystallo optical spectroscopy data-analysis toolbox is demonstrated.

    Reliable food composition data are required for virtually all nutrition-related programs and policies. In many food composition tables, fish are included to a limited extent. Therefore, FAO/INFOODS decided to compile and publish a user databases for fish and shellfish (uFiSh), considering the following main objectives: to develop a global database for fish, crustaceans and molluscs with raw, cooked and processed foods; to base the database preferable on analytical data; to include major as well as minor species consumed; and to capture intra-species variation due to habitat, edible part, season or region. The development of the uFiSh is based on FAO/INFOODS international standards and guidelines. The paper describes challenges and possible solution of data compilation specific to fish and shellfish, as well as the uFiSh in terms of its structure, including coverage of nutrients, documentation and format of publication. The first edition is intended to be published in 2015. PMID:26433296

    RNA interference (RNAi) is an evolutionary conserved highly specific gene-silencing mechanism initiated by small interfering RNA (siRNA) molecules. Fast-paced preclinical and clinical studies helped the siRNA technology become an efficient tool for undruggable targets in different diseases including genetic diseases, viral diseases and cancer. Despite great feature of siRNAs that can down-regulate any protein in the cells, the full potential and the success of the preclinical studies could not be translated into largely successful clinical outcomes. It has become clear that the possibility of overcoming the pitfalls for in vivo siRNA therapy fully depends on delivery systems. In this review, we start with the challenges and barriers for in vivo siRNA delivery. Then we briefly discuss the recent developments in siRNA modification technology. We specifically focused on siRNA lipidation and delivery approaches with special emphasis on the lipid based hybrid systems. Here we summarize the journey of lipid-based micelle-like nanoparticle systems that combine longevity in blood, effective cellular uptake and endosomal escape for successful siRNA delivery and discuss the multifunctional stimuli-sensitive systems based on lipids as the next generation smart systems.

    2016-01-01

    There are numerous reviews and meta-analyses that confirm that psychological therapy is efficacious for patients with rheumatoid arthritis (RA) in terms of managing pain. Therefore, the literature has moved on to answer additional questions: 1) What types of interventions are most strongly supported by the current evidence? 2) Do different patients benefit from different approaches? 3) When is it best to intervene? 4) What modalities are best for administering the intervention? 5) What model of care should we be proposing that will result in widespread implementation and will ensure access for patients with RA? This review concludes that cognitive behavioral therapy (CBT) is the most efficacious treatment for pain management in RA; however, there are indications that mindfulness may have particular benefits for patients with a history of depression. CBT is most effective when administered early in the course of the disease. However, there is at present little evidence to confirm whether or not psychosocial interventions are effective for patients with comorbid psychological disorders. One of the major challenges is ensuring access to effective interventions for patients, particularly early on in the course of the disease, with a view to preventing physical and psychological morbidity. A stepped-care model is proposed; however, we urgently need more, better-quality trials of minimal interventions, particularly in Internet-delivered CBT, which appears promising and may form the cornerstone of future stepped-care models for providing psychosocial care to patients with RA.

    Nowadays, smart composite materials embed miniaturized sensors for structural health monitoring (SHM) in order to mitigate the risk of failure due to an overload or to unwanted inhomogeneity resulting from the fabrication process. Optical fiber sensors, and more particularly fiber Bragg grating (FBG) sensors, outperform traditional sensor technologies, as they are lightweight, small in size and offer convenient multiplexing capabilities with remote operation. They have thus been extensively associated to composite materials to study their behavior for further SHM purposes. This paper reviews the main challenges arising from the use of FBGs in composite materials. The focus will be made on issues related to temperature-strain discrimination, demodulation of the amplitude spectrum during and after the curing process as well as connection between the embedded optical fibers and the surroundings. The main strategies developed in each of these three topics will be summarized and compared, demonstrating the large progress that has been made in this field in the past few years. PMID:24763215

    The Nile-Delta is subjected to continuous changes; including shoreline changes either erosion or accretion, subsidence of the delta, as well as sea level rise due to climate change. The impacts of climate change on the Nile Delta have been addressed on local and international level as the Nile Delta coastal zones are vulnerable to sea level rise. The poster presents recent research activities and findings from the CLIMB project in the Nile Delta and costal zones of Egypt. Lots of field data have been collected such as aquifer geometry data, soil properties data, well data and contamination sources. All of these data support a coupled modeling approach of the land surface hydrological model WASIM-ETH and the hydrological model MOD-Flow to simulate and project the future impact translation of climate projections into hydrological impacts. Results confirm intensified threads to water security. Increasing potential evaporation (in response to increasing temperature) in combination with decreasing water levels in the Nile river, reduced precipitation and groundwater recharge and deteriorating groundwater quality, imposes great challenges to ensure the supply of drinking water and irrigation. Current irrigation strategies are highly inefficient and must be replaced by new and adapted systems. Based on the results of the coupled modeling approach, various scenarios can be evaluated. The vision is to develop a road map for climate change and green economy that maximizes wellbeing of the Egyptian citizens, operates with environmental limits, and is capable of adapting to global environmental change.

  12. Neuroontology, neurobiological naturalism, and consciousness: A challenge to scientific reduction and a solution

    2012-03-01

    One of the great challenges to a science of consciousness is the inability to reduce critical features of consciousness to neural processes. In this paper I identify four neuroontologically irreducible features (NOIF) - referral of neural states, mental unity, qualia, and mental causation - defined as aspects of consciousness in which subjective experience is not wholly reducible to objectively observed or objectively understood neurons (ontological subjectivity). I next analyze the emergent and unique system properties of the neural hierarchy and argue that while the NOIF are indeed ontologically subjective, each of the NOIF individually can be explained by the unique architecture and functional properties of the neural hierarchy that lead to both emergent properties and their irreducibility in a manner that does not violate any known physical laws nor require any new physics or the application of physics to emergence or reduction beyond that normally applied to biology in general. I conclude that consciousness is a neurobiologically unique and local phenomenon that is specific to particular neural systems, a view that is consistent with both ontological subjectivity and biological naturalism. I call this position weakly emergent nonreductive physicalism or neurobiological naturalism.

    Improved access to anti-retroviral therapy increases the need for affordable monitoring using assays such as CD4 and/or viral load in resource-limited settings. Barriers to accessing treatment, high rates of loss to initiation and poor retention in care are prompting the need to find alternatives to conventional centralized laboratory testing in certain countries. Strong advocacy has led to a rapidly expanding repertoire of point-of-care tests for HIV. point-of-care testing is not without its challenges: poor regulatory control, lack of guidelines, absence of quality monitoring and lack of industry standards for connectivity, to name a few. The management of HIV increasingly requires a multidisciplinary testing approach involving hematology, chemistry, and tests associated with the management of non-communicable diseases, thus added expertise is needed. This is further complicated by additional human resource requirements and the need for continuous training, a sustainable supply chain, and reimbursement strategies. It is clear that to ensure appropriate national implementation either in a tiered laboratory model or a total decentralized model, clear country-specific assessments need to be conducted.

    Modern biotechnology, in combination with chemistry and process technology, is crucial for the development of new clean and cost effective manufacturing concepts for fine-chemical, food specialty and pharmaceutical products. The impact of biocatalysis on the fine-chemicals industry is presented, where reduction of process development time, the number of reaction steps and the amount of waste generated per kg of end product are the main targets. Integration of biosynthesis and organic chemistry is seen as a key development. The advances in bioseparation technology need to keep pace with the rate of development of novel bio- or chemocatalytic process routes with revised demands on process technology. The need for novel integrated reactors is also presented. The necessary acceleration of process development and reduction of the time-to-market seem well possible, particularly by integrating high-speed experimental techniques and predictive modelling tools. This is crucial for the development of a more sustainable fine-chemicals industry. The evolution of novel 'green' production routes for semi-synthetic antibiotics (SSAs) that are replacing existing chemical processes serves as a recent and relevant case study of this ongoing integration of disciplines. We will also show some challenges in this specific field. PMID:12747542

    The Tissue Engineering & Regenerative Medicine International Society-Europe (TERMIS-EU) Industry Committee as well as its TERMIS-Americas (AM) counterpart intend to address the specific challenges and needs facing the industry in translating academic research into commercial products. Over the last 3 years, the TERMIS-EU Industry Committee has worked with commercial bodies to deliver programs that encourage academics to liaise with industry in proactive collaborations. The TERMIS-EU 2013 Industry Symposium aimed to build on this commercial agenda by focusing on two topics: Operations Management (How to move a process into the good manufacturing practice [GMP] environment) and Clinical Translation (Moving a GMP process into robust trials). These topics were introduced by providing the synergistic business perspective of partnering between the multiple regenerative medicine stakeholders, throughout the life cycle of product development. Seven industry leaders were invited to share their experience, expertise, and strategies. Due to the complex nature of regenerative medicine products, partnering for their successful commercial development seems inevitable to overcome all obstacles by sharing experiences and expertise of all stakeholders. When ideally implemented, the "innovation quotient" of a virtual team resulting from the combination of internal and external project teams can be maximized through maximizing the three main dimensions: core competences, technology portfolio, and alliance management.

    A full-scale membrane bioreactor (1,600 m(3) d(-1)) was monitored for modelling purposes during the summer of 2006. A complete calibration of the ASM1 model is presented, in which the key points were the wastewater characterisation, the oxygen transfer and the biomass kinetics. Total BOD tests were not able to correctly estimate the biodegradable fraction of the wastewater. Therefore the wastewater fractionation was identified by adjusting the simulated sludge production rate to the measured value. MLVSS and MLSS were accurately predicted during both calibration and validation periods (20 and 30 days). Because the membranes were immerged in the aeration tank, the coarse bubble and fine bubble diffusion systems coexisted in the same tank. This allowed five different aeration combinations, depending whether the 2 systems were operating separately or simultaneously, and at low speed or high speed. The aeration control maintained low DO concentrations, allowing simultaneous nitrification and denitrification. This made it difficult to calibrate the oxygen transfer. The nitrogen removal kinetics were determined using maximum nitrification rate tests and an 8-hour intensive sampling campaign. Despite the challenges encountered, a calibrated set of parameters was identified for ASM1 that gave very satisfactory results for the calibration period. Matching simulated and measured data became more difficult during the validation period, mainly because the dominant aeration configuration had changed. However, the merit of this study is to be the first effort to simulate a full-scale MBR plant. PMID:21076205

    Infections in critically ill patients are associated with persistently poor clinical outcomes. These patients have severely altered and variable antibiotic pharmacokinetics and are infected by less susceptible pathogens. Antibiotic dosing that does not account for these features is likely to result in suboptimum outcomes. In this Review, we explore the challenges related to patients and pathogens that contribute to inadequate antibiotic dosing and discuss how to implement a process for individualised antibiotic therapy that increases the accuracy of dosing and optimises care for critically ill patients. To improve antibiotic dosing, any physiological changes in patients that could alter antibiotic concentrations should first be established; such changes include altered fluid status, changes in serum albumin concentrations and renal and hepatic function, and microvascular failure. Second, antibiotic susceptibility of pathogens should be confirmed with microbiological techniques. Data for bacterial susceptibility could then be combined with measured data for antibiotic concentrations (when available) in clinical dosing software, which uses pharmacokinetic/pharmacodynamic derived models from critically ill patients to predict accurately the dosing needs for individual patients. Individualisation of dosing could optimise antibiotic exposure and maximise effectiveness. PMID:24768475

    Hyperphosphataemia is a clinical consequence of the advanced stages of chronic kidney disease (CKD). Considerable evidence points to a role of hyperphosphataemia in the pathogenesis of CKD-associated cardiovascular (CV) complications, including vascular calcification, and with increased all-cause and CV mortality. These observations place management of hyperphosphataemia at the centre of CKD treatment. Although our increased understanding of the physiological role of FGF-23 may provide a long-term alternative biomarker of phosphate load and underlying disease progression, regular determination of serum phosphate is currently the most frequently used parameter to evaluate phosphate load in clinical practice. This review considers the challenges physicians and patients face in trying to control hyperphosphataemia. Amongst these are the limitations of dietary phosphate restriction, giving rise to the need for phosphate binder therapy to maintain serum phosphate control. Once the decision to use phosphate binders has been made, considerations include the relative efficacy, different potential side effects and pill burden associated with various phosphate binders. Although a number of phosphate binders are available, adherence poses a major obstacle to effective treatment. This emphasizes that further improvements to phosphate binder therapy can be made. Evaluation of novel agents and their potential role in the clinic should continue. PMID:26019840

    Many workers have questions about occupational safety and health (OSH). Answers to these questions empower them to further improve their knowledge about OSH, make good decisions about OSH matters and improve OSH practice when necessary. Nevertheless, many workers fail to find the answers to their questions. This paper explores the challenges workers may face when seeking answers to their OSH questions. Findings suggest that many workers may lack the skills, experience or motivation to formulate an answerable question, seek and find information, appraise information, compose correct answers and apply information in OSH practice. Simultaneously, OSH knowledge infrastructures often insufficiently support workers in answering their OSH questions. This paper discusses several potentially attractive strategies for developing and improving OSH knowledge infrastructures: 1) providing courses that teach workers to ask answerable questions and to train them to find, appraise and apply information, 2) developing information and communication technology tools or facilities that support workers as they complete one or more stages in the process from question to answer and 3) tailoring information and implementation strategies to the workers' needs and context to ensure that the information can be applied to OSH practice more easily.

    Both China and UNEP recommend replacing raw coal chunks with coal briquettes in household sector as clean coal technology (CCT), which has been confirmed by the decreased emissions of particulate matter and black carbon. However, the clean effect has never been systematically checked by other pollutants like polycyclic aromatic hydrocarbons (PAHs). In this study, 5 coals with different geological maturities were processed as both chunks and briquettes and burned in 3 typical coal stoves for the measurement of emission factors (EFs) of particle-bound PAHs. It was found that the EFs of 16 parent PAHs, 26 nitrated PAHs, 6 oxygenated PAHs, and 8 alkylated PAHs for coal briquettes were 6.90 ± 7.89, 0.04 ± 0.03, 0.65 ± 0.40, and 72.78 ± 18.23 mg/kg, respectively, which were approximately 3.1, 3.7, 1.9, and 171 times those for coal chunks, respectively. Such significant increases in PAH emissions increased human health risk and challenged the policy of CCT. PMID:25912887

    There is a high prevalence of drug trafficking and misuse in Asia. Drugs grown in Afghanistan are trafficked through Iran and Pakistan to the rest of the world. This has led to an increase in the prevalence of drug use disorders in these regions, especially heroin. This has in turn led to an increase in the use of syringes and syringe sharing which has resulted in the exponential spread of blood borne diseases such as HIV/AIDS. A lack of awareness of the detrimental use of heroin, syringe sharing and the concept of HIV has been revealed. The literature reviewed provides evidence for a change in policy with an increase in epidemiological and clinical research in these regions as well as an increase in public awareness. PMID:25440559

    This article analyzes tobacco control policies in hospitals based on the experience of the Catalan Network of Smoke-Free Hospitals, Spain. The objective is to understand through this case study how tobacco policies are designed and implemented in health care organizations. Because tobacco control is a public health issue, governmental, institutional, and professional involvement is necessary. This article identifies and examines the structure and relationships among the different actors involved in the tobacco control policies in health care organizations using Ostrom's Institutional Analysis and Development framework.This theory helps one understand the policy failures and rethink the future challenges. Critical issues should be reviewed to enhance implementation of smoke-free hospitals-such as assuring the compliance of nonsmoking areas and introducing compulsory tobacco cessation activities that are promoted and monitored by the public administration. The author suggests that relying primarily on an organization's interpretation of rules leads to irregular implementation. PMID:19900946

    There is tremendous unmet and sometimes unrealized need for Earth and space science (ESS) expertise as part of civic decisions and local planning for climate change, natural hazards and natural resources. The Thriving Earth Exchange (TEX) helps AGU contribute that expertise to humanity in respectful, integrated ways. TEX brings ESS scientists together with local communities tackling issues of climate change, natural hazards and natural resources to co-design solutions that equitably integrate both scientific and community knowledge. To achieve this ambitious goal, TEX is partnering with organizations that are respected by and knowledgeable about communities both in the United States and internationally. Such partnerships include Rockefeller's 100 Resilient Cities Initiative, ICLEI USA, MIT's Climate Colab, among others. TEX works with these partners to approach communities who are ready to or already addressing ESS related issues. With partners, we help the communities define their goals, develop specific projects, and connect with relevant and helpful ESS scientists. We will also show how we help scientists and community leaders work productively together, and the tools we bring to support their innovation. It will highlight international examples, such as in the Pamir Mountains of Afghanistan-Tajikistan, Sri Lanka, and Ethiopia, and provide concrete examples of how these initiatives are helping TEX further expand the frontiers of collaborative research.

    The transboundary basins of Colorado (Baja California) and Rio Bravo (Grande) have low water availability figures and water will be appreciated as a highly valued good. In the Rio Grande basin, the strategies and actions have been developed with the River Basin Council: a new surface water management, new water allocation rules for different rainfall and runoff scenarios (climate change included), new sources of water and establishment of water reserves for human consumption and for environmental purposes. In the Colorado River, with an integrated watershed management vision, Mexican and US federal, state and non-governmental organizations representatives signed Minute 319 for 5 years without changing the 1944 Water Treaty. Concepts and rules for surplus, shortage, Intentionally Created Mexican Water (ICMA), salinity, water for the environment and international projects were included and are been implemented. Parallel drinking water and sanitation services in both sides of the border through the Joint Investment Program, EPA-CONAGUA invested 979.2 million dollars from grants to improve the quality of the environment and the inhabitants. Accomplishments are high and the reduction in river health is a good indicator. The implementation of this binational cooperation actions under the framework of the 1944 Water Treaty are considered global solutions in the field of integrated water management in transboundary basins and for creating water security in highly pressured basins.

    ESA’s Solar Orbiter mission is conceived to perform a close-up study of the Sun and the inner heliosphere. With a perihelion close at 0.29 AU and a maximum aphelion at about 0.85 AU, Solar Orbiter ventures closer to the Sun than any spacecraft before. Furthermore, about 3 years after launch, the spacecraft will begin an out-of-ecliptic phase, with inclinations gradually increasing up to 30 degrees. Solar Orbiter will be launched in 2017 and its nominal mission will last until 2024 (with the possibility of an extended mission until 2026). It will provide unique data and imagery of the Sun. The Extreme Ultraviolet Imager (EUI) suite onboard Solar Orbiter is composed of two High Resolution Imagers (HRI, one at Lyman-alpha and one at 174 Angstrom), and one dual band Full-Sun imager (FSI) working alternatively at the 174 and 304 Angstrom EUV passbands. The EUI Data Center (EDC), under PI supervision and located at the Royal Observatory of Belgium (Brussels), will be the single point of contact for instrument planning activities and for data deliveries to the Solar Orbiter archive at ESAC (Madrid), and is currently in its design phase. The EUI Data Center will be responsible for delivery to ESAC and the maintenance of the pipeline software that will process EUI data from telemetry packets to higher level data products. It will also ensure the delivery of these data products to the Solar Orbiter Data Archive, and maintain the instrument user manual that documents the processing of EUI non-science TM packets at ESOC (Darmstadt). The EDC will monitor any anomaly affecting the EUI instrument and produce on a regular basis the Instrument Operations Reports including an instrument health and science performance review. Here, we present an overview of the EDC and how it envisages to tackle some specific challenges. Since EUI will only observe during three “science windows” of 10 days each per orbit of about 165 days and in view of a severely limited telemetry, it is

    A number of simulation platforms have been developed to study the spatiotemporal variability of hydrologic responses to global change. Sophisticated terrestrial models demand large data sets and considerable computing resources as they attempt to include detailed physics for all relevant processes involving the feedbacks between subsurface, land surface and atmospheric processes. Access to required data scarcity, error and uncertainty; allocation of computing resources; and post processing/analysis are some of the well-known challenges. And have been discussed in previous studies dealing with catchments ranging from plot scale research (102m2), to small experimental catchments (0.1-10km2), and occasionally medium-sized catchments (102-103km2). However, there is still a lack of knowledge about large-scale simulations of the coupled terrestrial mass and energy balance over long time scales (years to decades). In this study, the interaction between subsurface, land surface, and the atmosphere are simulated in two large scale (>104km2) river catchments that are the Luanhe catchment in the North Plain, China and the Rur catchment, Germany. As a simulation platform, a fully coupled model (ParFlow.CLM) that links a three-dimensional variably-saturated groundwater flow model (ParFlow) with a land surface model (CLM) is used. The Luanhe and the Rur catchments have areas of 54,000 and 28,224km2 respectively and are being simulated using spatial resolutions on the order of 102 to 103m in the horizontal and 10-2 to 10-1m in the vertical direction. ParFlow.CLM was configured over computational domains well beyond the actual watershed boundaries to account for cross-watershed flow. The resulting catchment models consist of up to 108 cells which were implemented over more than 1000 processors each with 512MB memory on JUGENE hosted by the Juelich Supercomputing Centre, Germany. Consequently, large numbers of input and output files were produced for each parameter such as; soil

    Many patients with Alzheimer’s disease will develop agitation at later stages of the disease, which constitutes one of the most challenging and distressing aspects of dementia. Recently, nonpharmacological therapies have become increasingly popular and have been proven to be effective in managing the behavioral symptoms (including agitation) that are common in the middle or later stages of dementia. These therapies seem to be a good alternative to pharmacological treatment to avoid unpleasant side effects. We present a systematic review of randomized controlled trials (RCTs) focused on the nonpharmacological management of agitation in Alzheimer’s disease (AD) patients aged 65 years and above. Of the 754 studies found, eight met the inclusion criteria. This review suggests that music therapy is optimal for the management of agitation in institutionalized patients with moderately severe and severe AD, particularly when the intervention includes individualized and interactive music. Bright light therapy has little and possibly no clinically significant effects with respect to observational ratings of agitation but decreases caregiver ratings of physical and verbal agitation. Therapeutic touch is effective for reducing physical nonaggressive behaviors but is not superior to simulated therapeutic touch or usual care for reducing physically aggressive and verbally agitated behaviors. Melissa oil aromatherapy and behavioral management techniques are not superior to placebo or pharmacological therapies for managing agitation in AD. Further research in clinical trials is required to confirm the effectiveness and long-term effects of nonpharmacological interventions for managing agitation in AD. These types of studies may lead to the development of future intervention protocols to improve the well-being and daily functioning of these patients, thereby avoiding residential care placement.

  13. Growth hormone therapy for Prader–willi syndrome: challenges and solutions

    Prader–Willi syndrome (PWS) is characterized by a dysregulation of growth hormone (GH)/insulin-like growth factor I axis, as the consequence of a complex hypothalamic involvement. PWS’ clinical picture seems to resemble the classic non-PWS GH deficiency (GHD), including short stature, excessive body fat, decreased muscle mass, and impaired quality of life. GH therapy is able to ameliorate the phenotypic appearance of the syndrome, as well as to improve body composition, physical strength, and cognitive level. In this regard, however, some pathophysiologic and clinical questions still remain, representing a challenge to give the most appropriate care to PWS patients. Data about the prevalence of GHD in PWS children are not unequivocal, ranging from 40% to 100%. In this context, to establish whether the presence (or not) of GHD may have a different effect on clinical course during GH therapy may be helpful. In addition, the comparison of GH effects in PWS children diagnosed as small for gestational age with those obtained in subjects born appropriate for gestational age is of potential interest for future trials. Emerging information seems to demonstrate the maintenance of beneficial effects of GH therapy in PWS subjects after adolescent years. Thus, GH retesting after achievement of final height should be taken into consideration for all PWS patients. However, it is noteworthy that GH administration exerts positive effects both in PWS adults with and without GHD. Another critical issue is to clarify whether the genotype–phenotype correlations may be relevant to specific outcome measures related to GH therapy. Moreover, progress of our understanding of the role of GH replacement and concomitant therapies on bone characteristics of PWS is required. Finally, a long-term surveillance of benefits and risks of GH therapy is strongly recommended for PWS population, since most of the current studies are uncontrolled and of short duration.

  15. Responding to Public Health Emergencies on Tribal Lands: Jurisdictional Challenges and Practical Solutions.

    Barnard, Justin B

    2015-01-01

    Response to public health emergencies on tribal lands poses a unique challenge for state and tribal public health officials. The complexity and intensely situation-specific nature of federal Indian jurisprudence leaves considerable question as to which government entity, state or tribal, has jurisdiction on tribal lands to undertake basic emergency measures such as closure of public spaces, quarantine, compulsory medical examination, and investigation. That jurisdictional uncertainty, coupled with cultural differences and an often troubled history of tribal-state relations, threatens to significantly impede response to infectious disease outbreaks or other public health emergencies on tribal lands. Given that tribal communities may be disproportionately impacted by public health emergencies, it is critical that tribal, state, and local governments engage with each other in coordinated planning for public health threats. This Article is offered as a catalyst for such planning efforts. The Article identifies some of the most pressing jurisdictional issues that may confront governments responding to a public health emergency on tribal lands, with the aim of highlighting the nature of the problem and the need for action. The Article goes on to examine the most promising means of addressing jurisdictional uncertainty: intergovernmental agreements. Already utilized in many areas of shared interest between tribe and state, intergovernmental agreements offer neighboring state, local, and tribal governments a vehicle for delineating roles and authorities in an emergency, and may lay the groundwork for sharing resources. The Article surveys various representative tribal public health intergovernmental agreements, and concludes with suggestions for tribes and state or local governments looking to craft their own agreements.

  16. Can biofuels be a solution to climate change? The implications of land use change-related emissions for policy

    Biofuels have gained increasing attention as an alternative to fossil fuels for several reasons, one of which is their potential to reduce the greenhouse gas (GHG) emissions from the transportation sector. Recent studies have questioned the validity of claims about the potential of biofuels to reduce GHG emissions relative to the liquid fossil fuels they are replacing when emissions owing to direct (DLUC) and indirect land use changes (ILUC) that accompany biofuels are included in the life cycle GHG intensity of biofuels. Studies estimate that the GHG emissions released from ILUC could more than offset the direct GHG savings by producing biofuels and replacing liquid fossil fuels and create a ‘carbon debt’ with a long payback period. The estimates of this payback period, however, vary widely across biofuels from different feedstocks and even for a single biofuel across different modelling assumptions. In the case of corn ethanol, this payback period is found to range from 15 to 200 years. We discuss the challenges in estimating the ILUC effect of a biofuel and differences across biofuels, and its sensitivity to the assumptions and policy scenarios considered by different economic models. We also discuss the implications of ILUC for designing policies that promote biofuels and seek to reduce GHG emissions. In a first-best setting, a global carbon tax is needed to set both DLUC and ILUC emissions to their optimal levels. However, it is unclear whether unilateral GHG mitigation policies, even if they penalize the ILUC-related emissions, would increase social welfare and lead to optimal emission levels. In the absence of a global carbon tax, incentivizing sustainable land use practices through certification standards, government regulations and market-based pressures may be a viable option for reducing ILUC.

    The deployment of regional and national Electronic Health Record solutions has been a focus of many countries throughout the past decade. A major challenge for these deployments has been support for ubiquitous image viewing. More specifically, these deployments require an imaging solution that can work over the Internet, leverage any point of service device: desktop, tablet, phone; and access imaging data from any source seamlessly. Whereas standards exist to enable ubiquitous image viewing, few if any solutions exist that leverage these standards and meet the challenge. Rather, most of the currently available web based DI viewing solutions are either proprietary solutions or require special plugins. We developed a true zero foot print browser based DI viewing solution based on the Web Access DICOM Objects (WADO) and Cross-enterprise Document Sharing for Imaging (XDS-I.b) standards to a) demonstrate that a truly ubiquitous image viewer can be deployed; b) identify the gaps in the current standards and the design challenges for developing such a solution. The objective was to develop a viewer, which works on all modern browsers on both desktop and mobile devices. The implementation allows basic viewing functionalities of scroll, zoom, pan and window leveling (limited). The major gaps identified in the current DICOM WADO standards are a lack of ability to allow any kind of 3D reconstruction or MPR views. Other design challenges explored include considerations related to optimization of the solution for response time and low memory foot print.

  19. High precision and high aspect ratio laser drilling: challenges and solutions

    Uchtmann, Hermann; He, Chao; Gillner, Arnold

    2016-03-01

    Laser drilling is a very versatile tool to produce high accuracy bores in small and large geometries using different technologies. In large and deep hole drilling laser drilling can be found in drilling cooling holes into turbomachinery components such as turbine blades. In micro drilling, the technology is used for the generation of nozzles and filters. However, especially in macro drilling, the process often causes microstructure changes and induces defects such as recast layers and cracks. The defects are caused by the melt dominated drilling process by using pulse durations in the range of some 100 μm up to a few ms. A solution of this problem is the use of ultrashort pulsed laser radiation with pulse durations in the range of some 100 fs up to a few ps, however with the disadvantage of long drilling times. Thus, the aim of this work is to combine the productive process by using ms pulsed fiber laser radiation with subsequent ablation of existing recast layers at the hole wall by using ultrashort pulsed laser radiation. By using fast scanning techniques the recast layer can be avoided almost completely. With a similar technology also very small hole can be produced. Using a rotating dove prism a circular oscillation of the laser spots is performed and holes are drilled at intervals in 1 mm thick stainless steel (1.4301) by ultra-short laser pulses of 7 ps at 515 nm. The formation of hole and the behavior of energy deposition differ from other drilling strategies due to the helical revolution. The temporal evolution of the hole shape is analyzed by means of SEM techniques from which three drilling phases can be distinguished.

    as two-way coded data. Good research governance is proposed as the way forward in the longer run. Good research governance is about a fair balance between the interests of all stakeholders. It should make the basic principles transparent on which observational research projects are based in line with European solidarity-based healthcare systems. It should encompass principles on how the general results of research will be disseminated, 'conflict of interests' policies, how the issues of intellectual property rights are dealt with, how the confidentiality of personal data of donors is maintained, etc. This should not become an extra bureaucratic layer. A good research governance framework should not establish rules but principles which provide enough flexibility for the specifics of a project, according to the 'comply or explain' principle. Such research governance should be developed bottom-up, by researchers together with the most interested stakeholders, patient organisations. Patients as 'biosocial citizens' are the natural allies of researchers against the 'paternalistic attitudes' of some ethicists and regulators. PMID:18440221
