    Full Text Available Abstract Despite the combination of favourable climate for parasites and vectors, and large populations of stray dogs, information concerning the epidemiology, diagnosis and management of canine vector-borne diseases in India is limited. However, with the country's expanding economy and adaptation to western culture, higher expectations and demands are being placed on veterinary surgeons for improved knowledge of diseases and control. This review aims to provide an overview of the current state of knowledge of these diseases in India and identify existing knowledge gaps in the literature which need to be addressed. The available literature on this subject, although limited, suggests that a number of canine vector-borne diseases such as filariasis, babesiosis and ehrlichiosis are endemic throughout India, as diagnosed mostly by morphological methods. Detailed investigations of the epidemiology and zoonotic potential of these pathogens has been neglected. Further study is essential to develop a better understanding of the diversity of canine vector-borne diseases in India, and their significance for veterinary and public health.

    Evidence of effectiveness does not equal successful implementation. To progress the field, practical tools are needed to bridge the gap between research and practice and to truly unite effectiveness and implementation evidence. This paper describes the Knowledge Transfer Scheme integrating existing implementation research frameworks into a tool which has been developed specifically to bridge the gap between knowledge derived from research on the one side and evidence-based usable information and tools for practice on the other.

    On 28th May 2016, mycetoma was recognized as a neglected tropical disease by the World Health Organization. This was the result of a 4-year journey starting in February 2013 with a meeting of global mycetoma experts. Knowledge gaps were identified and included the incidence, prevalence, and mapping of mycetoma; the mode of transmission; the development of methods for early diagnosis; and better treatment. In this review, we review the road to recognition, the ISHAM working group meeting in Argentina, and we address the progress made in closing the knowledge gaps since 2013. Progress included adding another 9000 patients to the literature, which allowed us to update the prevalence map on mycetoma. Furthermore, based on molecular phylogeny, species names were corrected and four novel mycetoma causative agents were identified. By mapping mycetoma causative agents an association with Acacia trees was found. For early diagnosis, three different isothermal amplification techniques were developed, and novel antigens were discovered. To develop better treatment strategies for mycetoma patients, in vitro susceptibility tests for the coelomycete agents of black grain mycetoma were developed, and the first randomized clinical trial for eumycetoma started early 2017.

    Eating disorders are unique in that they inherently have much medical comorbidity both as a part of restricting-type eating disorders and those characterized by purging behaviors. Over the last three decades, remarkable progress has been made in the understanding and treatment of the medical complications of eating disorders. Yet, unfortunately, there is much research that is sorely needed to bridge the gap between current medical knowledge and more effective and evidence-based medical treatment knowledge. These gaps exist in many different clinical areas including cardiology, electrolytes, gastrointestinal and bone disease. In this paper, we discuss some of the knowledge gap areas, which if bridged would help develop more effective medical intervention for this population of patients.

    Tapir and Krill are declarative languages for specifying actions and agents, respectively, that can be executed in simulation. As such, they bridge the gap between strictly declarative knowledge bases and strictly executable code. Tapir and Krill components can be combined to produce models of activity which can answer questions about mechanisms and processes using conventional inference methods and simulation. Tapir was used in DARPA's Rapid Knowledge Formation (RKF) project to construct models of military tactics from the Army Field Manual FM3-90. These were then used to build Courses of Actions (COAs) which could be critiqued by declarative reasoning or via Monte Carlo simulation. Tapir and Krill can be read and written by non-knowledge engineers making it an excellent vehicle for Subject Matter Experts to build and critique knowledge bases.

    Hindman, Douglas Blanks; Yan, Changmin

    2015-08-01

    The knowledge gap hypothesis predicts widening disparities in knowledge of heavily publicized public affairs issues among socioeconomic status groups. The belief gap hypothesis extends the knowledge gap hypothesis to account for knowledge and beliefs about politically contested issues based on empirically verifiable information. This analysis of 3 national surveys shows belief gaps developed between liberals and conservatives regarding abstinence-only sex education; socioeconomic status-based knowledge gaps did not widen. The findings partially support both belief gap and knowledge gap hypotheses. In addition, the unique contributions of exposure to Fox News, CNN, and MSNBC in this process were investigated. Only exposure to Fox News was linked to beliefs about abstinence-only sex education directly and indirectly through the cultivation of conservative ideology.

  15. The Existence Of Revenue Gap In South Africa

    Directory of Open Access Journals (Sweden)

    Thamae Retselisitsoe

    2015-08-01

    Full Text Available The paper provides an empirical analysis of the macroeconomic factors that enhance revenue gap in South Africa using the multivariate cointegration techniques for the period 1965 to 2012. The results from the cointegration analysis indicate that the revenue gap in South Africa is negatively associated with the level of imports while positively related to external debt and underground economy. The former finding is consistent with the notion that imports are subjected to more taxation than domestic activities because of certain features of international trade that tend to make tax evasion difficult. On the other hand, the positive relationship between external debt and tax gap shows that the South African government relies upon external debt to finance its budget deficit resulting from missing revenues. Furthermore, the observed negative effect of the post-apartheid dummy confirms that the tax policy reforms that South Africa introduced following the liberation in 1994 have led to a reduction in missing revenues. The results from the Granger causality test also show that there is a unidirectional causality running from imports and underground economy to revenue gap, while revenue gap on the other hand is found to Granger-cause national income and external debt in South Africa.

    To better understand the level of concussion knowledge of youth female hockey coaches and to identify preferred methods of knowledge translation for this population. Cross-sectional survey. Participants independently completed written surveys before in-person concussion information sessions or online surveys through link provided in emails. Convenience sampling yielded 130 coaches of youth female hockey from Canada. Knowledge level on concussion, resources from which coaches obtained information on concussion, opinions on the current level of concussion knowledge, and knowledge translation. Coaches demonstrated adequate knowledge on concussion, achieving 84% correct on true-false questions and 92% correct on symptom identification accuracy. However, coaches showed limited awareness of concussion specific to mechanisms for injury (identification) and postconcussion symptoms. Internet resources were rated as the most used resources for concussion yet were not rated very helpful. Nonetheless, coaches indicated online courses and web sites as the most preferred method for concussion knowledge translation. Youth female hockey coaches have overall adequate knowledge of concussion; however, gaps in knowledge do exist. Future efforts to raise the concussion knowledge among coaches of female youth hockey should include information specific to the mechanism of injury, along with sign and symptom identification, with particular attention paid to emotional symptoms. Given the reported preferences and the widespread availability of the Internet, further exploration and research validation of online courses and web sites tailored to the youth female hockey community is encouraged.

    Resistance to antiretroviral therapy (ART) threatens the efficacy of human immunodeficiency virus type 1 (HIV-1) treatment. We present a review of knowledge gaps in the science and technologies of acquired HIV-1 drug resistance (HIVDR) in an effort to facilitate research, scientific exchange, and progress in clinical management. The expert authorship of this review convened to identify data gaps that exist in the field of HIVDR and discuss their clinical implications. A subsequent literature review of trials and current practices was carried out to provide supporting evidence. Several gaps were identified across HIVDR science and technology. A summary of the major gaps is presented, with an expert discussion of their implications within the context of the wider field. Crucial to optimizing the use of ART will be improved understanding of protease inhibitors and, in particular, integrase strand transfer inhibitors (INSTI) in the context of HIVDR. Limited experience with INSTI represents an important knowledge gap in HIV resistance science. Utilizing such knowledge in a clinical setting relies on accurate testing and analysis of resistance-associated mutations. As next-generation sequencing becomes more widely available, a gap in the interpretation of data is the lack of a defined, clinically relevant threshold of minority variants. Further research will provide evidence on where such thresholds lie and how they can be most effectively applied. Expert discussion identified a series of gaps in our knowledge of HIVDR. Addressing prefsuch gaps through further research and characterization will facilitate the optimal use of ART therapies and technologies.

    Cselkó, Zsuzsa; Pénzes, Melinda

    2016-06-19

    The decreasing proportion of smokers due to smoking restrictions have led producers to invent and disseminate electronic cigarettes (e-cigarettes) worldwide as a new form of nicotine enjoyment. This review summarizes the existing knowledge about e-cigarettes based on publications of PubMed, and on reviews and research data published by national and international scientific institutions. Present knowledge about the composition of e-cigarettes confirms that they are harmful products since their vapor is equally detrimental to the health of users and bystanders. Their benefits in smoking cessation still have not been justified by adequate scientific evidence, however, it has been proven that e-cigarettes uphold nicotine addiction and may increase the risk of starting conventional cigarette use by youth. In order to ensure the results of tobacco control policy and to assist smoking cessation, the same regulations are to be applied to e-cigarettes as to conventional tobacco products.

    2016-01-01

    Safety-net patients' socioeconomic barriers interact with limited digital and health literacies to produce a "knowledge gap" that impacts the delivery of healthcare via telehealth technologies. Six focus groups (2 African- American and 4 Latino) were conducted with patients who received teleretinal screening in a U.S. urban safety-net setting. Focus groups were analyzed using a modified grounded theory methodology. Findings indicate that patients' knowledge gap is primarily produced at three points during the delivery of care: (1) exacerbation of patients' pre-existing personal barriers in the clinical setting; (2) encounters with technology during screening; and (3) lack of follow up after the visit. This knowledge gap produces confusion, potentially limiting patients' perceptions of care and their ability to manage their own care. It may be ameliorated through delivery of patient education focused on both disease pathology and specific role of telehealth technologies in disease management.

  10. Media use and HIV/AIDS knowledge: a knowledge gap perspective.

    2014-12-01

    Despite the widespread utilization of the mass media in HIV/AIDS prevention, little is known about the knowledge gap that results from disparities in mass media use. This study examined the relationship between HIV/AIDS-related mass media use and HIV/AIDS-related knowledge among urban and rural residents of northwestern Ethiopia. A hierarchical regression analysis indicated that HIV/AIDS-related mass media use has both sequestering and mainstreaming effects in certain segments of the study population, although it was not a significant predictor of HIV/AIDS-related knowledge in the total population. The knowledge gaps between individuals with high and low education and between individuals who experience high and low levels of interpersonal communication about HIV/AIDS narrowed as HIV/AIDS-related media use increased, but the gap between urban and rural residents widened. The widening gap could be explained by differences in perceptions of information salience and several theoretical assumptions. Current mass media information campaigns, which are often prepared and broadcast from urban centers, may not only fail to improve the HIV/AIDS knowledge of the rural populace but also put rural populations at a disadvantage relative to their urban counterparts. Communication interventions informed by socioecological models might be helpful to redress and/or narrow the widening knowledge gap between urban and rural residents. © The Author (2013).

  11. Internet Use and the Political Knowledge Gap in Spain

    Directory of Open Access Journals (Sweden)

    2012-04-01

    Full Text Available Media availability and fragmentation and the resulting possibilities of content selection have risen dramatically with the expansion of new digital media. Previous research has found that this may increase knowledge gaps among citizens with different resources and motivations. This article analyses how Internet use affects political knowledge gaps due to education and to political interest in Spain. As expected, frequent Internet users are more knowledgeable about politics than non-users. Furthermore, Internet use increases knowledge more for the highly educated than for citizens with lower levels of education. Thus, the political knowledge gap related to education seems to be growing with the introduction of new media. However, the knowledge gap between citizens with high and low levels of political interest is smaller for frequent Internet users than for non-users. These findings provide a complex picture and partially contradict the pessimistic theory about the impact of increasing media choice on political knowledge.

    La disponibilidad y fragmentación de medios de comunicación y las posibilidades de elegir contenidos han aumentado en gran medida a raíz de la expansión de los medios digitales. Éstos pueden, según investigaciones anteriores, incrementar las diferencias en los niveles de conocimiento entre ciudadanos con distintas características. En este artículo se analiza cómo el uso de Internet afecta a las diferencias en el conocimiento político según el nivel educativo y el interés por la política en España. Los usuarios frecuentes de Internet saben más sobre política que los no usuarios, como era de esperar. Además, el uso de Internet incrementa el conocimiento político de manera más intensa para los usuarios con niveles educativos más elevados. Por tanto, parece que las diferencias en los niveles de conocimiento pueden estar creciendo con la expansión de los medios digitales. Sin embargo, las diferencias

    Since the discovery of mimivirus, its unusual structural and genomic features have raised great interest in the study of its biology; however, many aspects concerning its replication cycle remain uncertain. In this study, extensive analyses of electron microscope images, as well as biological assay results, shed light on unclear points concerning the mimivirus replication cycle. We found that treatment with cytochalasin, a phagocytosis inhibitor, negatively impacted the incorporation of mimivirus particles by Acanthamoeba castellanii , causing a negative effect on viral growth in amoeba monolayers. Treatment of amoebas with bafilomicin significantly impacted mimivirus uncoating and replication. In conjunction with microscopic analyses, these data suggest that mimiviruses indeed depend on phagocytosis for entry into amoebas, and particle uncoating (and stargate opening) appears to be dependent on phagosome acidification. In-depth analyses of particle morphogenesis suggest that the mimivirus capsids are assembled from growing lamellar structures. Despite proposals from previous studies that genome acquisition occurs before the acquisition of fibrils, our results clearly demonstrate that the genome and fibrils can be acquired simultaneously. Our data suggest the existence of a specific area surrounding the core of the viral factory where particles acquire the surface fibrils. Furthermore, we reinforce the concept that defective particles can be formed even in the absence of virophages. Our work provides new information about unexplored steps in the life cycle of mimivirus. IMPORTANCE Investigating the viral life cycle is essential to a better understanding of virus biology. The combination of biological assays and microscopic images allows a clear view of the biological features of viruses. Since the discovery of mimivirus, many studies have been conducted to characterize its replication cycle, but many knowledge gaps remain to be filled. In this study, we conducted a

    To understand individuals' financial behaviors, it is important to understand the financial knowledge gap - the distance between one's objective and subjective financial knowledge. Overestimating one's financial knowledge can lead to risky financial behaviors. To date, limited empirical work has examined how financial knowledge gap varies across age groups. We analyze the size and nature of the financial knowledge gap and its variation across age groups. Using nationally representative data, we find robust evidence that older adults overestimate their financial knowledge. Social workers can assess the financial knowledge gap and educate their clients to protect from financial fraud, exploitation, and abuse.

    Aziato, Lydia; Adejumo, Oluyinka

    2014-03-01

    There are concerns about adequacy of nurses' knowledge and skill in effective pain management since effective pain management promotes early recovery after surgery. This study explores factors that accounted for Ghanaian nurses' inadequate knowledge of postoperative pain management using a focused ethnographic design for data collection at a tertiary teaching hospital in Ghana. Fourteen nurses designated as key informants with different backgrounds as nurse educators and leaders were purposively sampled to participate. Data were collected through in-depth individual interviews; all interviews were conducted in English, audio-taped and transcribed verbatim. The study revealed that nurses' inadequate pain management knowledge might have resulted from curriculum gaps during training; inadequate clinical supervision, study days, and workshops for practising nurses; lack of funding for organising regular workshops; and, negative attitudes of nurses whereby new information learned at workshops was not readily applied in clinical practice. It was concluded that nursing curricula at all levels of training in Ghana should incorporate credit-bearing courses on pain management, and appropriate pain management education programmes should be instituted for practising nurses. Regular monitoring and evaluation of the impact of such education programs is required. Copyright © 2013 Elsevier Ltd. All rights reserved.

    The Lunar Exploration Analysis Group (LEAG) was tasked by the Human Exploration Operations Mission Directorate (HEOMD) to establish a Specific Action Team (SAT) to review lunar Strategic Knowledge Gaps (SKGs) within the context of new lunar data and some specific human mission scenarios. Within this review, the SAT was to identify the SKGs that have been fully or partially retired, identify new SKGs resulting from new data and observations, and review quantitative descriptions of measurements that are required to fill knowledge gaps, the fidelity of the measurements needed, and if relevant, provide examples of existing instruments or potential missions capable of filling the SKGs.

    Fragment based screening (FBS) has emerged as a mainstream lead discovery strategy in academia, biotechnology start-ups, and large pharma. As a prerequisite of FBS, a structurally diverse library of fragments is desirable in order to identify chemical matter that will interact with the range of diverse target classes that are prosecuted in contemporary screening campaigns. In addition, it is also desirable to offer synthetically amenable starting points to increase the probability of a successful fragment evolution through medicinal chemistry. Herein we describe a method to identify biologically relevant chemical substructures that are missing from an existing fragment library (chemical gaps), and organize these chemical gaps hierarchically so that medicinal chemists can efficiently navigate the prioritized chemical space and subsequently select purchasable fragments for inclusion in an enhanced fragment library.

    Canadian nuclear power plants were constructed in the 1960's through the 1980's. Fire safety considerations were largely based on guidance from general building and fire codes in effect at the time. Since then, nuclear specific fire safety standards have been developed and adopted by the Regulator, increasing the expected level of fire safety in the process. Application of the standards to existing plants was largely limited to operational requirements viewed as retroactive. However, as existing facilities undergo modifications or refurbishment for the purpose of life extension, the expectation is that the design requirements of these fire safety standards also be satisfied. This creates considerable challenges for existing nuclear power plants as fire safety requirements such as those intended to assure means for safe egress, prevention of fire spread and protection of redundancy rely upon fire protection features that are inherent in the physical infrastructural design. This paper focuses on the methodology for conducting fire safety gap analyses on existing plants, and the integral role that engineering judgement plays in the development of viable and cost effective solutions to achieve the objectives of the current fire safety standards.

    2010-12-01

    Full Text Available This article addresses the management of agricultural indigenous knowledge (IK in developing countries, with a specific focus on Tanzania. It provides background details on IK and its importance for agricultural development. It introduces various knowledge management (KM concepts and discusses their application in managing IK in the developing world by placing Nonaka’s knowledge creation theory (Nonaka 1991; Nonaka & Takeuchi 1995; Nonaka, Toyama & Konno 2000 in the context of the local communities. Data from focus groups were used to triangulate with data from interviews in order to validate, confirm and corroborate quantitative results with qualitative findings. The study findings showed that knowledge creation theory can be used to manage IK in the local communities, however, adequate and appropriate resources need to be allocated for capturing and preserving IK before it disappears altogether. For sustainable agricultural development, the communities have to be placed within a knowledge-creating setting that continuously creates, distributes and shares knowledge within and beyond the communities’ boundaries and integrates it with new agricultural technologies, innovations and knowledge.

    1982-08-01

    Purpose of this report is to examine the function of several existing institutions and to show how they could be effectively used to transmit information about waste repositories for long times into the future. Scope of this report is limited to a discussion of four institutional approaches to the dissemination and retention of information: Widely distributed maps, the marker system of the National Geodetic Survey, the archiving of documents, and one-call systems designed to protect underground utility installations from inadvertent damage by the public. Each of these approaches is discussed in an independent section that describes the background of the institutional approach, discusses methods for applying it to waste repositories, and assesses its potential value. The sole intent of this report is to present supporting data for future decisions about the kinds of communication measures that should be implemented to advise future generations about the locations and hazards of waste repositories

    2013-06-01

    Sleep has been linked to a host of physical, behavioral, and emotional outcomes, and research has documented that youth across the globe are experiencing inadequate sleep. Despite this knowledge, however, very little research has been conducted on school-age children; much of the extant research has focused on infants, toddlers, preschoolers, adolescents, and adults. School-age children exhibit increasing independence around health-related behaviors, which provide health professionals the opportunity to educate and promote healthy sleep behaviors. This commentary extends previous research reviews by identifying the current gaps in sleep research, highlighting future directions needed in sleep research, and explaining why school nurses are best suited to address this growing public health issue.

    Petrol has been extracted from Achuar territory in the Northern Peruvian Amazon since the 1970s. In spite of early identification of negative impacts on the environment and repeated attempts by the Achuar to improve conditions, very little research has been done on specific environmental and health impacts. Some recent governmental studies have shown extremely high blood lead and cadmium levels in Achuar communities. In this paper we apply an environmental justice framework to review the evidence of pollution and health status available in existing studies, as well as government and operating company actions over the last 30 years. We identify gaps in our knowledge which hamper efforts to respond to the environmental and health situation, as well as negligent actions on the part of the State and petrol companies.

    2014-01-01

    The development of next generation nuclear systems is predicated on improvement in sustainability, safety, proliferation resistance and economics. The economic assessment of the reactor concept is required as early as in the concept development stage. The Generation IV International Forum (GIF) has developed a methodology for economic assessment of the Generation IV (GEN-IV) nuclear energy systems. The GIF economics methodology was used for the assessment of one of the reactor concepts for the Super-Critical Water-cooled Reactors (SCWR), namely the European pressure-vessel type concept referred to as the High Performance Light Water Reactor (HPLWR). The economic analysis involved studying the sensitivity of two main economic indicators, namely, the Levelized Unit Electricity Cost (LUEC) and the Total Capital Investment Cost (TCIC). The knowledge gaps in estimating the capital costs and fuel costs, as well as the uncertainties in other cost parameters affecting the economic assessment of the nuclear energy system in the concept development stage are presented.

    2013-11-01

    Full Text Available β-carotene is the most abundant provitamin A carotenoid in human diet and tissues. It exerts a number of beneficial functions in mammals, including humans, owing to its ability to generate vitamin A as well as to emerging crucial signaling functions of its metabolites. Even though β-carotene is generally considered a safer form of vitamin A due to its highly regulated intestinal absorption, detrimental effects have also been ascribed to its intake, at least under specific circumstances. A better understanding of the metabolism of β-carotene is still needed to unequivocally discriminate the conditions under which it may exert beneficial or detrimental effects on human health and thus to enable the formulation of dietary recommendations adequate for different groups of individuals and populations worldwide. Here we provide a general overview of the metabolism of this vitamin A precursor in mammals with the aim of identifying the gaps in knowledge that call for immediate attention. We highlight the main questions that remain to be answered in regards to the cleavage, uptake, extracellular and intracellular transport of β-carotene as well as the interactions between the metabolism of β-carotene and that of other macronutrients such as lipids.

    Conservation agriculture (CA) practices of reduced soil tillage, permanent organic soil coverage and intercropping/crop rotation, are being advocated globally, based on perceived benefits for crop yields, soil carbon storage, weed suppression, reduced soil erosion and improved soil water retention. However, some have questioned their efficacy due to uncertainty around the performance and trade-offs associated with CA practices, and their compatibility with the diverse livelihood strategies and varied agro-ecological conditions across African smallholder systems. This paper assesses the role of key institutions in Malawi in shaping pathways towards more sustainable land management based on CA by outlining their impact on national policy-making and the design and implementation of agricultural development projects. It draws on interviews at national, district and project levels and a multi-stakeholder workshop that mapped the institutional landscape of decision-making for agricultural land management practices. Findings identify knowledge gaps and institutional barriers that influence land management decision-making and constrain CA uptake. We use our findings to set out an integrated roadmap of research needs and policy options aimed at supporting CA as a route to enhanced sustainable land management in Malawi. Findings offer lessons that can inform design, planning and implementation of CA projects, and identify the multi-level institutional support structures required for mainstreaming sustainable land management in sub-Saharan Africa.

  13. Bridging the PSI Knowledge Gap: A Multi-Scale Approach

    Energy Technology Data Exchange (ETDEWEB)

    Wirth, Brian D. [Univ. of Tennessee, Knoxville, TN (United States)

    2015-01-08

    Plasma-surface interactions (PSI) pose an immense scientific hurdle in magnetic confinement fusion and our present understanding of PSI in confinement environments is highly inadequate; indeed, a recent Fusion Energy Sciences Advisory Committee report found that 4 out of the 5 top five fusion knowledge gaps were related to PSI. The time is appropriate to develop a concentrated and synergistic science effort that would expand, exploit and integrate the wealth of laboratory ion-beam and plasma research, as well as exciting new computational tools, towards the goal of bridging the PSI knowledge gap. This effort would broadly advance plasma and material sciences, while providing critical knowledge towards progress in fusion PSI. This project involves the development of a Science Center focused on a new approach to PSI science; an approach that both exploits access to state-of-the-art PSI experiments and modeling, as well as confinement devices. The organizing principle is to develop synergistic experimental and modeling tools that treat the truly coupled multi-scale aspect of the PSI issues in confinement devices. This is motivated by the simple observation that while typical lab experiments and models allow independent manipulation of controlling variables, the confinement PSI environment is essentially self-determined with few outside controls. This means that processes that may be treated independently in laboratory experiments, because they involve vastly different physical and time scales, will now affect one another in the confinement environment. Also, lab experiments cannot simultaneously match all exposure conditions found in confinement devices typically forcing a linear extrapolation of lab results. At the same time programmatic limitations prevent confinement experiments alone from answering many key PSI questions. The resolution to this problem is to usefully exploit access to PSI science in lab devices, while retooling our thinking from a linear and de

    This PhD dissertation focuses on energy efficiency policies in housing. It aims at evaluating the effectiveness of public incentives designed to increase household's investment in energy efficiency of their dwelling. To reach this objective this research combines the two key dimensions of ex-post evaluation, i.e. summary and formative dimensions. The first one aims at knowing the effectiveness of public policies whereas the other one targets to understand what the public policies' consequences are and to identify ways for improvement. To reach this purpose, the research follows four steps. Firstly, it requires a detailed analysis to understand the origins of the energy efficiency gap. This gap can be explained by markets failures, consequences of bounded rationality and coordination problem between stakeholders, especially in multi-family dwellings. Secondly, the argument progresses by drawing a parallel between results from normative analysis and from observations of actual level of investments in thermal retrofit actions. It aims at identifying investment households' criteria and then at understanding how barriers to energy efficiency raise. Thirdly, thanks to the inventory of these various energy efficiency barriers it becomes possible to examine if the incentives currently implemented in France can remove them all. It appears that the national policy does not significantly reduce the energy efficiency gap. On the one hand, some barriers remain because no tool has been proposed to overcome them. On the other hand, some barriers are only partially eliminated because the practical use of tools differs from their theoretical design. Finally, using the analysis of retrofitting programs implemented on the Grenoble area this research assesses the effectiveness of additional incentives. The objective is to know to what extent these 'reinforced' policies remove barriers still existing after national tools implementation. From these four

    One of the cornerstones of the sustainable biochar concept is to improve, or at least to not deteriorate, soil quality and functioning. The idea of global sustainable biochar systems, with biochar applied to global cropland and grassland soils, has highlighted limitations in: i) current scientific understanding of biochar interactions with soil components, ii) the capacity to assess ecosystem services provided by soils, and iii) the uncertainty in spatio-temporal representation of both (i) and (ii). Pyrolysis conditions and feedstock characteristics largely control the physico-chemical properties of the resulting biochar, which in turn determine the suitability for a given application. Soils are highly heterogeneous systems at a range of scales. Combinations of land use, soil management and changing climatic conditions further enhance this heterogeneity. While this leads to difficulties in identifying the underlying mechanisms behind reported effects in the scientific literature, it also provides an opportunity for 'critical matching' of biochar properties that are best suited to a particular site (depending on soil type, hydrology, climate, land use, soil contaminants, etc.). Biochar's relatively long mean residence times in soils (100s of years) make it a potential instrument for sequestering carbon (if done sustainably). However, that same long mean residence time sets biochar apart from conventional soil amendments (such as manures and other organic fertilizers) that are considered as transient in the soil (1-10s of years). The functional life time of biochar in soils essentially moves biochar from a soil management tool to a geo-engineering technique. One of the consequences is that desired ecosystem services that are provided by soils, have to be projected for the same time period. This presentation aims to discuss critical knowledge gaps in biochar-soil-ecosystem interactions against a background of ecosystem services.

    As greater numbers of photovoltaic (PV) systems are being installed, operations & maintenance (O&M) activities will need to be performed to ensure the PV system is operating as designed over its useful lifetime. To mitigate risks to PV system availability and performance, standardized procedures for O&M activities are needed to ensure high reliability and long-term system bankability. Efforts are just getting underway to address the need for standard O&M procedures as PV gains a larger share of U.S. generation capacity. Due to the existing landscape of how and where PV is installed, including distributed generation from small and medium PV systems, as well as large, centralized utility-scale PV, O&M activities will require different levels of expertise and reporting, making standards even more important. This report summarizes recent efforts made by solar industry stakeholders to identify the existing standards and best practices applied to solar PV O&M activities, and determine the gaps that have yet to be, or are currently being addressed by industry.

  19. Arizona Registered Dietitians Show Gaps in Knowledge of Bean Health Benefits

    2018-01-01

    Registered Dietitians (RDs) promote nutrition practices and policies and can influence food consumption patterns to include nutrient dense foods such as beans. Although many evidence-based health benefits of bean consumption (e.g., cholesterol reduction, glycemic control) have been demonstrated, there is limited research on the knowledge, attitudes, and perceptions of RDs regarding the inclusion of beans in a healthy diet. To fill this existing research gap, this cross-sectional survey explored the perceptions, knowledge, and attitudes of 296 RDs in Arizona, USA, toward beans. The RDs largely held positive attitudes toward the healthfulness of beans and were aware of many health benefits. Some gaps in awareness were evident, including effect on cancer risk, intestinal health benefits, folate content, and application with celiac disease patients. RDs with greater personal bean consumption had significantly higher bean health benefit knowledge. Twenty-nine percent of the RDs did not know the meaning of ‘legume’, and over two-thirds could not define the term ‘pulse’. It is essential that RDs have up-to-date, evidence-based information regarding bean benefits to provide appropriate education to patients, clients, and the public. PMID:29316699

    2014-11-01

    Despite rapid growth in the rate of adoption of health information technology (HIT), and in the volume of evaluation studies, the existing knowledge base for the value of HIT is not advancing at a similar rate. Most evaluation articles are limited in that they use incomplete measures of value and fail to report the important contextual and implementation characteristics that would allow for an adequate understanding of how the study results were achieved. To address these deficiencies, we present a conceptual framework for measuring HIT value and we propose a checklist of characteristics that should be considered in HIT evaluation studies. The framework consists of 3 key principles: 1) value includes both costs and benefits; 2) value accrues over time; and 3) value depends on which stakeholder's perspective is used. Through examples, we show how these principles can be used to guide and improve HIT evaluation studies. The checklist includes a list of contextual and implementation characteristics that are important for interpretation of results. These improvements will make future studies more useful for policy makers and more relevant to the current needs of the healthcare system.

    Using data from a national survey of South Koreans, this study explores the role of science communication in enhancing three different forms of scientific knowledge ( factual, procedural, and subjective). We first assess learning effects, looking at the extent to which citizens learn science from different channels of communication (interpersonal discussions, traditional newspapers, television, online newspapers, and social media). We then look into the knowledge gap hypothesis, investigating how different communication channels can either widen or narrow the gap in knowledge between social classes. Television was found to function as a "knowledge leveler," narrowing the gap between highly and less educated South Koreans. The role of online newspapers in science learning is pronounced in our research. Reading newspapers online indicated a positive relationship to all three measures of knowledge. Contrary to the knowledge-leveling effect of television viewing, reading online newspapers was found to increase, rather than decrease, the gap in knowledge. Implications of our findings are discussed in detail.

    Most weather data is produced, disseminated and consumed by expert users in large national operational centers or laboratories. Data 'ages' off their systems in days or weeks. While archives exist, would-be users often lack the credentials necessary to obtain an account to access or search its contents. Moreover, operational centers and many national archives lack the mandate and the resources to serve non-expert users. The National Center for Atmospheric Research (NCAR) Research Data Archive (RDA), rda.ucar.edu, was created over 40 years ago to collect data for NCAR's internal Big Science projects such as the NCEP/NCAR Reanalysis Project. Over time, the data holdings have grown to 1.8+ Petabytes spanning 600+ datasets. The user base has also grown; in 2014, we served 1.1 Petabytes of data to over 11,000 unique users. The RDA works with national centers, such as NCEP, ECMWF and JMA to make their data available to worldwide audiences and mutually support data access at the production source. We have become not just an open-access data center, but also a data education center. Each dataset archived at the RDA is assigned to a data specialist (DS) who curates the data. If a user has a question not answered in the dataset information web pages prepared by the DS, they can call or email a skilled DS for further clarification. The RDA's diverse staff—with academic training in meteorology, oceanography, engineering (electrical, civil, ocean and database), mathematics, physics, chemistry and information science—means we likely have someone who "speaks your language." Erroneous data assumptions are the Achilles heel of Big Data. It doesn't matter how much data you crunch if the data is not what you think it is. Data discovery is another difficult Big Data problem; one can only solve problems with data if one can find the right data. Metadata, both machine and human-generated, underpin the RDA data search tools. The RDA has stepped in to fill the gap between data

  4. Identifying knowledge gaps for gene drive research to control invasive animal species: The next CRISPR step

    Full Text Available Invasive animals have been linked to the extinctions of native wildlife, and to significant agricultural financial losses or impacts. Current approaches to control invasive species require ongoing resources and management over large geographic scales, and often result in the short-term suppression of populations. New and innovative approaches are warranted. Recently, the RNA guided gene drive system based on CRISPR/Cas9 is being proposed as a potential gene editing tool that could be used by wildlife managers as a non-lethal addition or alternative to help reduce pest animal populations. While regulatory control and social acceptance are crucial issues that must be addressed, there is an opportunity now to identify the knowledge and research gaps that exist for some important invasive species. Here we systematically determine the knowledge gaps for pest species for which gene drives could potentially be applied. We apply a conceptual ecological risk framework within the gene drive context within an Australian environment to identify key requirements for undertaking work on seven exemplar invasive species in Australia. This framework allows an evaluation of the potential research on an invasive species of interest and within a gene drive and risk context. We consider the currently available biological, genetic and ecological information for the house mouse, European red fox, feral cat, European rabbit, cane toad, black rat and European starling to evaluate knowledge gaps and identify candidate species for future research. We discuss these findings in the context of future thematic areas of research worth pursuing in preparation for a more formal assessment of the use of gene drives as a novel strategy for the control of these and other invasive species.

    The GAP between the knowledge of contraception and its actual practice is well recognized in the literature of family welfare studies. The present study assessed the relation between the level of knowledge and practice of contraception among the women and sought to explore the reasons behind the Knowledge, Attitude, and Practice - GAP (KAP GAP) regarding contraceptive users in six cities of Uttar Pradesh. Present analysis based on 17,643 currently married women aged 15 to 49. A Bivariate analysis ( χ 2 test) and a multivariable logistic regression were performed for the study. The highest percentages of respondents (women) were in the age group 35-49 (40-45 %) in all the districts considered. Knowledge of contraceptives was almost universal; tubal ligation and pill were the commonly known methods. Information about the contraceptive methods was mostly obtained through the husband. In the present study, there was a highly significant association ( p  GAP for all six cities. Health concern issues in all the districts were the most prominent reason for not using contraception. There differences in the socioeconomic and demographic factors exist, which lead to KAP GAP in the family planning (FP) usages. Therefore, in designing effective family planning programme, there is a need to understand the various factors which influence the practice of contraception.

    Web security became an alert in internet computing. To cope with ever-rising security complexity, semantic analysis is proposed to fill-in the gap that the current approaches fail to commit. Conventional methods limit their focus to the physical source codes instead of the abstraction of semantics. It bypasses new types of vulnerability and causes tremendous business loss.

  7. Two approaches to bridging the knowledge-practice gap in oncology nursing.

    The field of oncology nursing is continually changing. New drugs to aid in the fight against cancer are being developed, complementary therapies to ease symptoms are gaining prominence, and survivorship care is becoming a welcome yet challenging area of subspecialty. For oncology nurses to provide quality care and to develop improved care delivery systems, they must not only have access to the most current knowledge in the field, but also be equipped with the skills necessary to integrate that knowledge into practice for the benefit of patients and families (LoBiondo-Wood et al., 2014). The importance of nursing research and its relationship to the practice of oncology nursing cannot be minimized (Moore & Badger, 2014). Oncology nurse researchers advance knowledge and, consequently, improve the quality of care for patients with cancer and their families. For example, the Oncology Nursing Society (ONS) regularly surveys its membership to identify key areas of research focus that then guide the work of nurse investigators (LoBiondo-Wood et al., 2014; ONS Research Agenda Team, 2009). Unfortunately, the shortage of nurse scientists, particularly in oncology nursing, continues to increase as senior doctoral faculty reach retirement age and doctoral education program development remains stagnant (Glasgow & Dreher, 2010; LoBiondo-Wood et al., 2014). This shortage has and will continue to lead to gaps in the generation and implementation of new knowledge, negatively affecting the quality of patient care. As a result, an urgent need exists for innovative and quality doctoral educational programs to develop nurse scientists (Moore & Badger, 2014).

  8. Teachers' instructional goals for science practice: Identifying knowledge gaps using cultural-historical activity theory (CHAT)

    Science.gov (United States)

    Farrar, Cynthia Hamen

    In AP Biology, the course goal, with respect to scientific acts and reasoning, has recently shifted toward a reform goal of science practice, where the goal is for students to have a scientific perspective that views science as a practice of a community rather than a body of knowledge. Given this recent shift, this study is interested in the gaps that may exist between an individual teacher's instructional goal and the goals of the AP Biology course. A Cultural-Historical Activity Theory (CHAT) methodology and perspective is used to analyze four teachers' knowledge, practice, and learning. Teachers have content knowledge for teaching, a form of knowledge that is unique for teaching called specialized content knowledge. This specialized content knowledge (SCK) defines their instructional goals, the student outcomes they ultimately aim to achieve with their students. The study employs a cultural-historical continuum of scientific acts and reasoning, which represents the development of the AP Biology goal over time, to study gaps in their instructional goal. The study also analyzes the contradictions within their teaching practice and how teachers address those contradictions to shift their instructional practice and learn. The findings suggest that teachers have different interpretations of the AP Biology goals of science practice, placing their instructional goal at different points along the continuum. Based on the location of their instructional goal, different micro-communities of teachers exist along the continuum, comprised of teachers with a shared goal, language, and culture of their AP Biology teaching. The in-depth study of one teacher's AP Biology teaching, using a CHAT perspective, provides a means for studying the mechanisms that connect SCK to classroom actions and ultimately to instructional practice. CHAT also reveals the nature and importance of contradictions or cognitive dissonance in teacher learning and the types of support teachers need to

    In August 2015, the Corona outbreak caused by Middle East respiratory syndrome coronavirus (MERS-CoV) was the 9th episode since June 2012 in Saudi Arabia. Little is known about the public awareness toward the nature or prevention of the disease. The aim of this work was to assess the knowledge of the adult population in Riyadh toward the MERS-CoV. In this cross-sectional survey, a self-administrated questionnaire was distributed to randomly selected participants visiting malls in Riyadh. The questionnaire contained measurable epidemiological and clinical MERS-CoV knowledge level variables and relevant source of information. The study included 676 participants. Mean age was 32.5 (±SD 8.6) years and 353 (47.8%) were males. Almost all participants heard about the corona disease and causative agent. The study showed a fair overall knowledge (66.0%), less knowledge on epidemiological features of the disease (58.3%), and good knowledge (90.7%) on the clinical manifestation of the MERS-CoV. Internet was the major (89.0%) source of disease information, and other sources including health care providers, SMS, television, magazines and books were low rated (all knowledge. This study concludes that there was inadequate epidemiological knowledge received by the public and the reliance mostly on the clinical manifestations to recognizing the MERS-CoV disease. Comprehensive public health education programs is important to increase awareness of simple epidemiological determinants of the disease is warranted. Copyright © 2017. Published by Elsevier Ltd.

    The practice of neurosurgery requires fundamental knowledge base. Residency training programs and continuing medical education courses are designed to teach relevant neurosurgical principles. Nevertheless, knowledge gaps exist for neurosurgeons and may be different between cohorts of neurosurgeons. The Self-Assessment in Neurological Surgery (SANS) General Examination and Spine Examination are online educational tools for lifelong learning and maintenance of certification. This study examines the gaps in knowledge of spinal neurosurgeons and general neurosurgeons taking SANS. From 2008 to 2010, a total of 165 spinal neurosurgeons completed the 243 available questions of the SANS Spine Examination. Over that same time frame, 993 general neurosurgeons completed the SANS General Spine Examination. Mean scores were calculated and assessed according to 18 major neurosurgical knowledge disciplines. Statistical analysis was carried out to evaluate for significant knowledge gaps among all users and significant differences in performance between spinal neurosurgeons and their general neurosurgeon counterparts. The mean overall examination score was 87.4% ± 7.5% for spinal neurosurgeons and 71.5% ± 8.9% for general neurosurgeons (P neurosurgeons (n = 165) answered questions incorrectly 15% or greater of the time in five of the categories. The categories of lower performance for spinal neurosurgeons were cerebrovascular, anesthesia and critical care, general clinical, tumor, and trauma. For general neurosurgeons (n = 993), the five knowledge categories with lowest performance were cerebrovascular, epilepsy, peripheral nerve, trauma, and radiosurgery. Although spinal neurosurgeons and general neurosurgeons shared some areas of decreased performance including trauma and cerebrovascular, spine neurosurgeons relatively underperformed in general clinical, anesthesia and critical care, and tumor. The SANS Spine Examination demonstrated knowledge gaps in specific categories for

    Full Text Available Nowadays, great amount of data is being created by several sources from academic, scientific, business and industrial activities. Such data intrinsically contains meaningful information allowing for developing techniques, and have scientific validity to explore the information thereof. In this connection, the aim of artificial intelligence (AI is getting new knowledge to make decisions properly. AI has taken an important place in scientific and technology development communities, and recently develops computer-based processing devices for modern machines. Under the premise, the premise that the feedback provided by human reasoning -which is holistic, flexible and parallel- may enhance the data analysis, the need for the integration of natural and artificial intelligence has emerged. Such an integration makes the process of knowledge discovery more effective, providing the ability to easily find hidden trends and patterns belonging to the database predictive model. As well, allowing for new observations and considerations from beforehand known data by using both data analysis methods and knowledge and skills from human reasoning. In this work, we review main basics and recent works on artificial and natural intelligence integration in order to introduce users and researchers on this emergent field. As well, key aspects to conceptually compare them are provided.

  18. Human strongyloidiasis: identifying knowledge gaps, with emphasis on environmental control

    Full Text Available Michael J Taylor, Tara A Garrard, Francis J O'Donahoo, Kirstin E Ross Health and Environment, School of the Environment, Flinders University, Adelaide, SA, Australia Abstract: Strongyloides is a human parasitic nematode that is poorly understood outside a clinical context. This article identifies gaps within the literature, with particular emphasis on gaps that are hindering environmental control of Strongyloides. The prevalence and distribution of Strongyloides is unclear. An estimate of 100–370 million people infected worldwide has been proposed; however, inaccuracy of diagnosis, unreliability of prevalence mapping, and the fact that strongyloidiasis remains a neglected disease suggest that the higher figure of more than 300 million cases is likely to be a more accurate estimate. The complexity of Strongyloides life cycle means that laboratory cultures cannot be maintained outside of a host. This currently limits the range of laboratory-based research, which is vital to controlling Strongyloides through environmental alteration or treatment. Successful clinical treatment with antihelminthic drugs has meant that controlling Strongyloides through environmental control, rather than clinical intervention, has been largely overlooked. These control measures may encompass alteration of the soil environment through physical means, such as desiccation or removal of nutrients, or through chemical or biological agents. Repeated antihelminthic treatment of individuals with recurrent strongyloidiasis has not been observed to result in the selection of resistant strains; however, this has not been explicitly demonstrated, and relying on such assumptions in the long-term may prove to be shortsighted. It is ultimately naive to assume that continued administration of antihelminthics will be without any negative long-term effects. In Australia, strongyloidiasis primarily affects Indigenous communities, including communities from arid central Australia. This

    Full Text Available Biological invasions are a major cause of global species change. Nevertheless, knowledge about the distribution and ecology of introduced species is regionally biased, and many gaps in knowledge exist for most developing countries.To study the zoobenthos on the hard substratum of the Ilha Grande Bay, a survey was conducted on both natural and artificial substrata at three depths and seven sites. The species recorded were classified as native, cryptogenic or introduced. Multivariate analyses were conducted to assess the prevalence of introduced species in these communities and to compare the distribution of species on natural and artificial substrata of this bay to identify possible discrepancies in habitat use. Of the 61 species, 25 were cryptogenic, 10 were introduced and 26 were native. Similar numbers of introduced species were found on both natural and artificial substrata, though the community composition was significantly different between them. We also compared the species composition of the Ilha Grande Bay survey to other inventories taken around the world. The highest similarities were found between the Ilha Grande Bay inventory and the Atlantic coastal region (Tampa Bay, USA and the Gulf of Mexico, American Samoa and Pearl Harbor (USA inventories.This study presents the first published comprehensive list of hard substratum sessile marine invertebrate species in a Brazilian bay. The high percentage of cryptogenic species reveals gaps in both zoological records and information on introduced species for the Brazilian coast. The introduced species successfully colonized different sites in the Ilha Grande Bay, including both natural and artificial substrata. In addition, we find that artificial structures may not be good surrogates for natural rocky shores and may represent an ecological threat. Comparisons with other inventories suggest a history of broad-scale invasion, though more evidence is needed to support this conclusion.

    Personalized medicine encompasses a broad and evolving field informed by a patient distinctive information and biomarker profile. Although terminology is evolving and some semantic interpretations exist (e.g., personalized, individualized, precision), in a broad sense personalized medicine can be coined as: "To practice medicine as it once used to be in the past using the current biotechnological tools." A humanized approach to personalized medicine would offer the possibility of exploiting systems biology and its concept of P5 medicine, where predictive factors for developing a disease should be examined within populations in order to establish preventive measures on at-risk individuals, for whom healthcare should be personalized and participatory. Herein, the process of personalized medicine is presented together with the options that can be offered in health care systems with limited resources for diseases like rheumatoid arthritis and type 1 diabetes.

    Gwairgi, Marina A; Ghildyal, Reena

    2018-03-22

    Entamoeba histolytica is the protozoan parasite that causes human amoebiasis. It is one of the leading parasitic disease burdens in tropical regions and developing countries, with spread to developed countries through migrants from and travellers to endemic regions. Understanding E. histolytica's invasion mechanisms requires an understanding of how it interacts with external cell components and how it engulfs and kills cells (phagocytosis). Recent research suggests that optimal phagocytosis requires signalling events from the cell surface to the nucleus via the cytoplasm, and the induction of several factors that are transported to the plasma membrane. Current research in other protozoans suggests the presence of proteins with nuclear localization signals, nuclear export signals and Ran proteins; however, there is limited literature on their functionality and their functional similarity to higher eukaryotes. Based on learnings from the development of antivirals, nuclear transport elements in E. histolytica may present viable, specific, therapeutic targets. In this review, we aim to summarize our limited knowledge of the eukaryotic nuclear transport mechanisms that are conserved and may function in E. histolytica.

    2011-03-01

    Seagrasses are habitats with significant ecological and economic functions but we have limited knowledge of seagrasses in Southeast Asia, the hypothesized centre-of-origin for tropical seagrasses. There have been only 62 ISI-cited publications on the seagrasses of Southeast Asia in the last three decades and most work has been in few sites such as Northwest Luzon in the Philippines and South Sulawesi in Indonesia. Our understanding of the processes driving spatial and temporal distributions of seagrass species here has focussed primarily on backreef and estuarine seagrass meadows, with little work on forereef systems. We used Pulau Tinggi, an island off the southeast coast of Peninsular Malaysia, as an example of a subtidal forereef system. It is characterized by a community of small and fast growing species such as Halophila ovalis (mean shoot density 1454.6 ± 145.1 m -2) and Halodule uninervis (mean shoot density 861.7 ± 372.0 m -2) growing in relatively low light conditions (mean PAR 162.1 ± 35.0 μmol m -2 s -1 at 10 m depth to 405.8 ± 99.0 μmol m -2 s -1 at 3 m water depth) on sediment with low carbonate (mean 9.24 ± 1.74 percentage dry weight), organic matter (mean 2.56 ± 0.35 percentage dry weight) and silt-clay content (mean 2.28 ± 2.43 percentage dry weight). The literature reveals that there is a range of drivers operating in Southeast Asian seagrass systems and we suggest that this is because there are various types of seagrass habitats in this region, i.e. backreef, forereef and estuary, each of which has site characteristics and ecological drivers unique to it. Based on our case study of Pulau Tinggi, we suggest that seagrasses in forereef systems are more widespread in Southeast Asia than is reflected in the literature and that they are likely to be driven by recurring disturbance events such as monsoons, sediment burial and herbivory.

    Risk perception is a key determinant of preventive health behaviour, but when asked, some individuals indicate they do not know their health risk. Low education is associated with both lack of knowledge about health risk and with the persistence and exacerbation of gaps in knowledge about health issues. This study uses the context of an emerging infectious disease threat to explore the hypothesis that the education-don't know risk relation results from differences in knowledge about the health issue of interest. Specifically, we examine whether patterns of change over time follow theoretical predictions that disparities in risk knowledge would increase over time in less educated sectors of the population (knowledge gap hypothesis). Secondary analysis of population-representative behavioural surveillance survey. We analysed data from the 1993 to 2000 Behavior Risk Factor Surveillance System surveys, which measured education and perceived HIV/AIDS risk in a population sample collected separately in each survey year; don't know responses were coded. In each year, individuals with higher education were less likely to respond don't know. The absolute prevalence of don't know responding dropped over time; nonetheless, there was an increase over time in the magnitude of the pattern of lower education being associated with greater don't know responding. We found support for the knowledge gap hypothesis. Over time, populations with greater education gained more knowledge about their HIV risk than populations with lower education. Results highlight the need to carefully consider health communication strategies to reach and address those individuals with low education and health knowledge. Statement of contribution What is already known on this subject? A meaningful potion of the population answers 'don't know' when asked to report their risk for health problems, indicating a lack of risk perception in the domain. Previous studies have shown that level of education is

  10. Life cycle assessment of engineered nanomaterials: state of the art and strategies to overcome existing gaps.

    Science.gov (United States)

    Hischier, Roland; Walser, Tobias

    2012-05-15

    The use of engineered nanomaterials offers advantages as well as disadvantages from a sustainability perspective. It is important to identify such points as early as possible in order to be able to build on existing strengths, while counteracting disadvantages. Life Cycle Assessment (LCA) is a suitable method to assess the environmental performance of a product or process. But so far studies applying LCA to the area of nanotechnology have been scarce. One reason might be that the LCA framework has a whole list of issues that need further precision in order to be applicable to nanotechnologies: system boundaries and a functional unit have to be chosen in a way that allows one to do a comparison of equal functionalities; adequate and comprehensive life cycle inventory data for engineered nanomaterials are the key on the level of inventory analysis; and the impact assessment step requires a clear definition of the degree of detail on the level of nanoparticle emissions. The LCA studies existing thus far in the area of nanotechnology have barely begun to cover all these aspects. Thus, in order to improve the current situation, the authors propose to go ahead in each of the LCA stages as far as scientific advances allow. For the inventory modelling this means e.g. that comprehensive, transparently documented and quality ensured data of the most important engineered nanomaterials should be collected and made available in a widely-accepted format. Concerning nanoparticle emissions, as many parameters as possible have to be collected pertaining to the production, use, and the disposal phase of these engineered nanomaterials. Furthermore, on the level of impact assessment, relevant physical characteristics have to be identified for a toxicity assessment of nanoparticles and a consensus has to be found for a limited but sufficient number of independent parameters influencing toxicity to be collected.

    Caste- and ethnicity-based inequalities are major obstacles to achieving health equity. The authors investigated whether there is any association between caste- and ethnicity-based inequalities and HIV-related knowledge within caste and ethnic populations. They used the 2011 Nepal Demographic and Health Survey, a nationally represented cross-sectional study data set. The study sample consisted of 11,273 women between 15 and 49 years of age. Univariate and logistic regression models were used to examine the relationship between caste- and ethnicity-based inequalities and HIV-related knowledge. The study sample was divided into high Hindu caste (47.9 percent), "untouchable" caste (18.4 percent), and indigenous populations (33.7 percent). Within the study sample, the high-caste population was found to have the greatest knowledge of the means by which HIV is prevented and transmitted. After controlling for socioeconomic and demographic characteristics, untouchables were the least knowledgeable. The odds ratio for incomplete knowledge about transmission among indigenous populations was 1.27 times higher than that for high Hindu castes, but there was no significant difference in knowledge of preventive measures. The findings suggest the existence of a prevailing HIV knowledge gap. This in turn suggests that appropriate steps need to be implemented to convey complete knowledge to underprivileged populations.

    The paper is aimed at bridging the gap between knowledge and practice and evaluating the impact of this activity on reduction of patient dose. While enormous data on radiation doses in diagnostic radiology exists, there is absolute lack of information at user's level. For example, the implications on patient dose from 1cm error in x-ray field size or error of 5 kVp or 5mAs is invariably not known. We estimated that 1 cm increase in field size results in irradiation of 600-900cc of extra volume of patient which may contain sensitive tissue, 5 kVp increase results in exposure of 35-65 mR, with more effect in case of lumbar spine and abdomen x-ray and lesser for chest and D-spine, 5 mAs error results in 4-25 mR. The impact of information supply to users was evaluated and it was found that information based approach results in dose reduction to patient and improved image quality.

  13. Giving what one should: explanations for the knowledge-behavior gap for altruistic giving.

    Blake, Peter R

    2018-04-01

    Several studies have shown that children struggle to give what they believe that they should: the so-called knowledge-behavior gap. Over a dozen recent Dictator Game studies find that, although young children believe that they should give half of a set of resources to a peer, they typically give less and often keep all of the resources for themselves. This article reviews recent evidence for five potential explanations for the gap and how children close it with age: self-regulation, social distance, theory of mind, moral knowledge and social learning. I conclude that self-regulation, social distance, and social learning show the most promising evidence for understanding the mechanisms that can close the gap. Copyright © 2017 Elsevier Ltd.

    Full Text Available Higher education institutions are investing increasing resources in order to achieve favourable perceptions among their stakeholders. However, image and reputation management is a complex issue and how stakeholders perceive universities does not always coincide with the image the latter wish to project. For this reason, in this article we address a review of the literature on higher education image and reputation to identify the main knowledge gaps and establish the research lines that merit deeper examination in the future. The gaps identified highlight the need to improve knowledge about the way perceptions (image and reputation of university institutions are shaped, pinpointing the dimensions or essential aspects that influence their formation and determining whether their degree of influence differs when considering the perspectives of different stakeholders or individuals from different geographical areas. Theoretical propositions related to the identified gaps have been set out.

    In pest risk assessment it is frequently necessary to make management decisions regarding emerging threats under severe uncertainty. Although risk maps provide useful decision support for invasive alien species, they rarely address knowledge gaps associated with the underlying risk model or how they may change the risk estimates. Failure to recognize uncertainty leads...

    Rogers, Donald W; Zavitsas, Andreas A

    2017-01-06

    Despite their abundance in nature and their importance in biology, medicine, nutrition, and in industry, gas phase enthalpies of formation of many long chain saturated and unsaturated fatty acids and of dicarboxylic acids are either unavailable or have been estimated with large uncertainties. Available experimental values for stearic acid show a spread of 68 kJ mol -1 . This work fills the knowledge gap by obtaining reliable values by quantum theoretical calculations using G4 model chemistry. Compounds with up to 20 carbon atoms are treated. The theoretical results are in excellent agreement with well established experimental values when such values exist, and they provide a large number of previously unavailable values.

    Given the high numbers of deaths and the debilitating nature of diseases caused by the use of unclean water it is imperative that we have an understanding of the factors that control the dispersion of water borne pathogens and their respective indicators. This is all the more important in developing countries where significant proportions of the population often have little or no access to clean drinking water supplies. Moreover, and notwithstanding the importance of these bacteria in terms of public health, at present little work exists on the persistence, transfer and proliferation of these pathogens and their respective indicator organisms, e.g., fecal indicator bacteria (FIB) such as Escherichia coli and fecal coliforms in humid tropical systems, such as are found in South East Asia or in the tropical regions of Africa. Both FIB and the waterborne pathogens they are supposed to indicate are particularly susceptible to shifts in water flow and quality and the predicted increases in rainfall and floods due to climate change will only exacerbate the problems of contamination. This will be furthermore compounded by the increasing urbanization and agricultural intensification that developing regions are experiencing. Therefore, recognizing and understanding the link between human activities, natural process and microbial functioning and their ultimate impacts on human health are prerequisites for reducing the risks to the exposed populations. Most of the existing work in tropical systems has been based on the application of temperate indicator organisms, models and mechanisms regardless of their applicability or appropriateness for tropical environments. Here, we present a short review on the factors that control FIB dynamics in temperate systems and discuss their applicability to tropical environments. We then highlight some of the knowledge gaps in order to stimulate future research in this field in the tropics.

    Malaria is one of the most important tropical diseases that has caused devastation throughout the history of mankind. Malaria eradication programmes in the past have had many positive effects but failed to wipe out malaria from most tropical countries, including Sri Lanka. Encouraged by the impressive levels of reduction in malaria case numbers during the past decade, Sri Lanka has launched a programme to eliminate malaria by year 2014. This article reviews the historical milestones associated with the malaria eradication programme that failed subsequently and the events that led to the launch of the ongoing malaria elimination plans at national-level and its strategies that are operational across the entire country. The existing gaps in knowledge are also discussed together with the priority areas for research to fill in these gaps that are posing as challenges to the envisaged goal of wiping out malaria from this island nation.

    Objective To explore the impact of the organisational quality systems on quality of care in Victorian health services. Methods During 2015 a total of 55 focus groups were conducted with more than 350 managers, clinical staff and board members in eight Victorian health services to explore the effectiveness of health service quality systems. A review of the quality and safety goals and strategies outlined in the strategic and operating plans of the participating health services was also undertaken. Results This paper focuses on the data related to the leadership role of health service boards in ensuring safe, high-quality care. The findings suggest that health service boards are not fully meeting their governance accountability to ensure consistently high-quality care. The data uncovered major clinical governance gaps between stated board and executive aspirations for quality and safety and the implementation of these expectations at point of care. These gaps were further compounded by quality system confusion, over-reliance on compliance, and inadequate staff engagement. Conclusion Based on the existing evidence we propose five specific actions boards can take to close the gaps, thereby supporting improved care for all consumers. What is known about this topic? Effective governance is essential for high-quality healthcare delivery. Boards are required to play an active role in their organisation's pursuit of high quality care. What does this paper add? Recent government reports suggest that Australian health service boards are not fully meeting their governance requirements for high quality, safe care delivery, and our research pinpoints key governance gaps. What are the implications for practitioners? Based on our research findings we outline five evidence-based actions for boards to improve their governance of quality care delivery. These actions focus on an organisational strategy for high-quality care, with the chief executive officer held accountable for

  8. Bridging the gap between knowledge and health: the epidemiologist as Accountable Health Advocate ("AHA!").

    Dowdy, David W; Pai, Madhukar

    2012-11-01

    Epidemiology occupies a unique role as a knowledge-generating scientific discipline with roots in the knowledge translation of public health practice. As our fund of incompletely-translated knowledge expands and as budgets for health research contract, epidemiology must rediscover and adapt its historical skill set in knowledge translation. The existing incentive structures of academic epidemiology - designed largely for knowledge generation - are ill-equipped to train and develop epidemiologists as knowledge translators. A useful heuristic is the epidemiologist as Accountable Health Advocate (AHA) who enables society to judge the value of research, develops new methods to translate existing knowledge into improved health, and actively engages with policymakers and society. Changes to incentive structures could include novel funding streams (and review), alternative publication practices, and parallel frameworks for professional advancement and promotion.

  10. Major Care Gaps in Asthma, Sleep and Chronic Obstructive Pulmonary Disease: A Road Map for Knowledge Translation

    Directory of Open Access Journals (Sweden)

    Louis-Philippe Boulet

    2013-01-01

    Full Text Available Large gaps between best evidence-based care and actual clinical practice exist in respiratory medicine, and carry a significant health burden. The authors reviewed two key care gaps in each of asthma, chronic obstructive pulmonary disease and obstructive sleep apnea. Using the ‘Knowledge-to-Action Framework’, the nature of each gap, its magnitude, the barriers that cause and perpetuate it, and past and future strategies that might address the problem were considered. In asthma: disease control is ascertained inadequately, leading to a prevalence of poor asthma control of approximately 50%; and asthma action plans, a key component of asthma management, are provided by only 22% of physicians. In obstructive sleep apnea: disease is under-recognized, with sleep histories ascertained in only 10% of patients; and Canadian polysomnography wait times remain longer than recommended, leading to unnecessary morbidity and societal cost. In chronic obstructive pulmonary disease: a large proportion of patients seen in primary care remain undiagnosed, mainly due to underuse of spirometry; and <10% of patients are referred for pulmonary rehabilitation, despite strong evidence demonstrating its cost effectiveness. Given the prevalence of these chronic conditions and the size and nature of these gaps, the latter exact an important toll on patients, the health care system and society. In turn, complex barriers at the patient, provider and health care system levels contribute to each gap. There have been few previous attempts to bridge these gaps. Innovative and multifaceted implementation approaches are needed and have the potential to make a large impact on Canadian respiratory health.

    In spite of much literature written about the theory-practice gap in the international nursing journals, there is evidence that indicates this subject has not been probed comprehensively since nursing education was transferred to universities in Iran. In the recent years, the public and the government have criticized Iranian nurses because of poor quality of patient care. Although this subject has been lamented by some researchers, there is no comprehensive work on how this gap resulted. In the process of a larger study on "nursing knowledge translation to practice", of one PhD thesis, this process was explored. Using grounded theory analysis, indepth interviews were undertaken with a purposive sample of 29 nurses, with different levels of experience, from the school of nursing in Tehran University of Medical Sciences in 2006 from January to August. Data were analyzed using the constant comparative method. Three main themes emerging from this study included clinical behavior structure, paradoxical knowledge and practice, and divergent nursing organization. It seems that nursing education with some praxis and paradoxes in the realm of nursing knowledge and practice, along with divergent organizational structure have decreased nurses' ability in applying their professional knowledge and skills in order to bridge the gap between theory and practice. Moreover, in spite of increased academic input into nursing education, clinical behaviors of both education and practice settings was perceived as "traditional routine-based".

    The goal of this study was to identify knowledge gaps in clinicians who evaluate and treat performing artists for illnesses and injuries that affect vocal function in college health settings. This pilot study utilized a web-based cross-sectional survey design incorporating common clinical scenarios to test knowledge of evaluation and management strategies in the vocal performing artist. A web-based survey was administered to a purposive sample of 28 clinicians to identify the approach utilized to evaluate and treat vocal performing artists in college health settings, and factors that might affect knowledge gaps and influence referral patterns to voice specialists. Twenty-eight clinicians were surveyed, with 36% of respondents incorrectly identifying appropriate vocal hygiene measures, 56% of respondents failing to identify symptoms of vocal fold hemorrhage, 84% failing to identify other indications for referral to a voice specialist, 96% of respondents acknowledging unfamiliarity with the Voice Handicap Index and the Singers Voice Handicap Index, and 68% acknowledging unfamiliarity with the Reflux Symptom Index. The data elucidated specific knowledge gaps in college health providers who are responsible for evaluating and treating common illnesses that affect vocal function, and triaging and referring students experiencing symptoms of potential vocal emergencies. Future work is needed to improve the standard of care for this population. Copyright © 2018 The Voice Foundation. Published by Elsevier Inc. All rights reserved.

    Many studies have explored the risk perception of frequent business travelers (FBT) toward malaria. However, less is known about their knowledge of other infectious diseases. This study aimed to identify knowledge gaps by determining the risk perception of FBT toward 11 infectious diseases. Our retrospective web-based survey assessed the accuracy of risk perception among a defined cohort of FBT for 11 infectious diseases. We used logistic regression and the chi-square test to determine the association of risk perception with source of travel advice, demographic variables, and features of trip preparation. Surveys were returned by 63% of the 608 self-registered FBT in Rijswijk, and only the 328 completed questionnaires that adhered to our inclusion criteria were used for analysis. The majority (71%) sought pre-travel health advice and used a company health source (83%). Participants seeking company travel health advice instead of external had significantly more accurate risk knowledge (p = 0.03), but more frequently overestimated typhoid risk (odds ratio = 2.03; 95% confidence interval = 1.23-3.34). While underestimation of disease risk was on average 23% more common than overestimation, HIV risk was overestimated by 75% of FBT. More accurate knowledge among FBT seeking company health advice demonstrates that access to in-company travel clinics can improve risk perception. However, there is an obvious need for risk knowledge improvement, given the overall underestimation of risk. The substantial overestimation of HIV risk is probably due to both public and in-company awareness efforts. Conversely, typhoid risk overestimation was statistically associated with seeking company health advice, and therefore specifically reflects the high focus on typhoid fever within Shell's travel clinic. This study serves as a reminder that a knowledge gap toward infectious diseases besides malaria still exists. Our article will explore the future requirements for more

    The problems facing administrative courts in determining 'existing knowledge in science and technology' (No. 3 of paragraph 2 of sect. 7 of the Atomic Energy Law) cannot be solved by limiting the judicial establishment of facts. According to established law, in procedural or substantive law there is no foundation for doing so. Limits to this establishment of facts do result from the nature of the scientific process of understanding, which very often allows but the establishment of 'margins' pertaining to scientific opinions.

  16. Pharmacogenomic knowledge gaps and educational resource needs among physicians in selected specialties

    2014-07-01

    Full Text Available Katherine A Johansen Taber, Barry D Dickinson Department of Science and Biotechnology, American Medical Association, Chicago, IL, USA Background: The use of pharmacogenomic testing in the clinical setting has the potential to improve the safety and effectiveness of drug therapy, yet studies have revealed that physicians lack knowledge about the topic of pharmacogenomics, and are not prepared to implement it in the clinical setting. This study further explores the pharmacogenomic knowledge deficit and educational resource needs among physicians. Materials and methods: Surveys of primary care physicians, cardiologists, and psychiatrists were conducted. Results: Few physicians reported familiarity with the topic of pharmacogenomics, but more reported confidence in their knowledge about the influence of genetics on drug therapy. Only a small minority had undergone formal training in pharmacogenomics, and a majority reported being unsure what type of pharmacogenomic tests were appropriate to order for the clinical situation. Respondents indicated that an ideal pharmacogenomic educational resource should be electronic and include such components as how to interpret pharmacogenomic test results, recommendations for prescribing, population subgroups most likely to be affected, and contact information for laboratories offering pharmacogenomic testing. Conclusion: Physicians continue to demonstrate pharmacogenomic knowledge gaps, and are unsure about how to use pharmacogenomic testing in clinical practice. Educational resources that are clinically oriented and easily accessible are preferred by physicians, and may best support appropriate clinical implementation of pharmacogenomics. Keywords: pharmacogenomics, knowledge gap, drug response, educational resource

    Timely access and ongoing delivery of care and therapeutic interventions is needed to maximize recovery and function after traumatic spinal cord injury (tSCI). To ensure these decisions are evidence-based, access to consistent, reliable, and valid sources of clinical data is required. The Access to Care and Timing Model used data from the Rick Hansen SCI Registry (RHSCIR) to generate a simulation of healthcare delivery for persons after tSCI and to test scenarios aimed at improving outcomes and reducing the economic burden of SCI. Through model development, we identified knowledge gaps and challenges in the literature and current health outcomes data collection throughout the continuum of SCI care. The objectives of this article were to describe these gaps and to provide recommendations for bridging them. Accurate information on injury severity after tSCI was hindered by difficulties in conducting neurological assessments and classifications of SCI (e.g., timing), variations in reporting, and the lack of a validated SCI-specific measure of associated injuries. There was also limited availability of reliable data on patient factors such as multi-morbidity and patient-reported measures. Knowledge gaps related to structures (e.g., protocols) and processes (e.g., costs) at each phase of care have prevented comprehensive evaluation of system performance. Addressing these knowledge gaps will enhance comparative and cost-effectiveness evaluations to inform decision-making and standards of care. Recommendations to do so were: standardize data element collection and facilitate database linkages, validate and adopt more outcome measures for SCI, and increase opportunities for collaborations with stakeholders from diverse backgrounds.

    The importance of consistent, accurate and unambiguous messages are well documented in oral health promotion literature. Whether the reality of delivering messages in the field fulfils these principle is questionable. This paper explores the perceptions of dental professionals, healthcare professionals and lay community members with regard to key oral health messages in order to highlight any inconsistencies and knowledge gaps between and within groups for disease risk factors. A questionnaire was administered to individuals who belonged to three groups: dental professionals, healthcare professionals and lay community members. The questionnaire established knowledge regarding risk factors for caries, periodontal disease and erosion. Thirty-five (57.4%) of the dental group answered the whole questionnaire correctly, with 22 (27.8%) and 9 (5.1%) of the healthcare and lay community group answering the whole questionnaire correctly, respectively. The question of fluoride levels in children's toothpaste was the main reason for incorrect answers in the dental group. The results of this survey demonstrate a knowledge gradient from dental professionals through to healthcare professionals and then to lay members of the community. The knowledge base observed in the dental group is reflected in the other two groups as would be expected albeit with a significant gap between each group. As expected the dental professionals are generally well informed, but not as well informed as could be expected.

    Urquhart, R; Grunfeld, E; Jackson, L; Sargeant, J; Porter, G A

    2013-12-01

    Health services researchers have consistently identified a gap between what is identified as "best practice" and what actually happens in clinical care. Despite nearly two decades of a growing evidence-based practice movement, narrowing the knowledge-practice gap continues to be a slow, complex, and poorly understood process. Here, we contend that cross-disciplinary research is increasingly relevant and important to reducing that gap, particularly research that encompasses the notion of transdisciplinarity, wherein multiple academic disciplines and non-academic individuals and groups are integrated into the research process. The assimilation of diverse perspectives, research approaches, and types of knowledge is potentially effective in helping research teams tackle real-world patient care issues, create more practice-based evidence, and translate the results to clinical and community care settings. The goals of this paper are to present and discuss cross-disciplinary approaches to health research and to provide two examples of how engaging in such research may optimize the use of research in cancer care.

    2017-01-01

    Responsiveness is a key objective of national health systems. Responsive health systems anticipate and adapt to existing and future health needs, thus contributing to better health outcomes. Of all the health systems objectives, responsiveness is the least studied, which perhaps reflects lack of comprehensive frameworks that go beyond the normative characteristics of responsive services. This paper contributes to a growing, yet limited, knowledge on this topic. Herewith, we review the current frameworks for understanding health systems responsiveness and drawing on these, as well as key frameworks from the wider public services literature, propose a comprehensive conceptual framework for health systems responsiveness. This paper should be of interest to different stakeholders who are engaged in analysing and improving health systems responsiveness. Our review shows that existing knowledge on health systems responsiveness can be extended along the three areas. First, responsiveness entails an actual experience of people’s interaction with their health system, which confirms or disconfirms their initial expectations of the system. Second, the experience of interaction is shaped by both the people and the health systems sides of this interaction. Third, different influences shape people’s interaction with their health system, ultimately affecting their resultant experiences. Therefore, recognition of both people and health systems sides of interaction and their key determinants would enhance the conceptualisations of responsiveness. Our proposed framework builds on, and advances, the core frameworks in the health systems literature. It positions the experience of interaction between people and health system as the centrepiece and recognises the determinants of responsiveness experience both from the health systems (eg, actors, processes) and the people (eg, initial expectations) sides. While we hope to trigger further thinking on the conceptualisation of health

    Family caregivers are an integral and increasingly overburdened part of the health care system. There is a gap between what research evidence shows is beneficial to caregivers and what is actually provided. Using an integrated knowledge translation approach, a stakeholder meeting was held among researchers, family caregivers, caregiver associations, clinicians, health care administrators, and policy makers. The objectives of the meeting were to review current research evidence and conduct multi-stakeholder dialogue on the potential gaps, facilitators, and barriers to the provision of caregiver supports. A two-day meeting was attended by 123 individuals. Three target populations of family caregivers were identified for discussion: caregivers of seniors with dementia, caregivers in end-of-life care, and caregivers of frail seniors with complex health needs. The results of this meeting can and are being used to inform the development of implementation research endeavours and policies targeted at providing evidence-informed caregiver supports.

    The Human Research Program (HRP) is formulated around the program architecture of Evidence-Risk-Gap-Task-Deliverable. Review of accumulated evidence forms the basis for identification of high priority risks to human health and performance in space exploration. Gaps in knowledge or disposition are identified for each risk, and a portfolio of research tasks is developed to fill them. Deliverables from the tasks inform the evidence base with the ultimate goal of defining the level of risk and reducing it to an acceptable level. A comprehensive framework for gap identification, focus, and metrics has been developed based on principles of continuous risk management and clinical care. Research towards knowledge gaps improves understanding of the likelihood, consequence or timeframe of the risk. Disposition gaps include development of standards or requirements for risk acceptance, development of countermeasures or technology to mitigate the risk, and yearly technology assessment related to watching developments related to the risk. Standard concepts from clinical care: prevention, diagnosis, treatment, monitoring, rehabilitation, and surveillance, can be used to focus gaps dealing with risk mitigation. The research plan for the new HRP Risk of Decompression Sickness (DCS) used the framework to identify one disposition gap related to establishment of a DCS standard for acceptable risk, two knowledge gaps related to DCS phenomenon and mission attributes, and three mitigation gaps focused on prediction, prevention, and new technology watch. These gaps were organized in this manner primarily based on target for closure and ease of organizing interim metrics so that gap status could be quantified. Additional considerations for the knowledge gaps were that one was highly design reference mission specific and the other gap was focused on DCS phenomenon.

    Effective and efficient reduction of natural hazard risks requires a thorough understanding of the costs of natural hazards in order to develop sustainable risk management strategies. The current methods that assess the costs of different natural hazards employ a diversity of terminologies and approaches for different hazards and impacted sectors. This makes it difficult to arrive at robust, comprehensive and comparable cost figures. The CONHAZ (Costs of Natural Hazards) project aimed to compile and synthesise current knowledge on cost assessment methods in order to strengthen the role of cost assessments in the development of integrated natural hazard management and adaptation planning. In order to achieve this, CONHAZ has adopted a comprehensive approach, considering natural hazards ranging from droughts, floods and coastal hazards to Alpine hazards, as well as different impacted sectors and cost types. Its specific objectives have been 1) to compile the state-of-the-art methods for cost assessment; 2) to analyse and assess these methods in terms of technical aspects, as well as terminology, data quality and availability, and research gaps; and 3) to synthesise resulting knowledge into recommendations and to identify further research needs. This presentation summarises the main results of CONHAZ. CONHAZ differentiates between direct tangible damages, losses due to business interruption, indirect damages, intangible effects, and costs of risk mitigation. It is shown that the main focus of cost assessment methods and their application in practice is on direct costs, while existing methods for assessing intangible and indirect effects are rather rarely applied and methods for assessing indirect effects often cannot be used on the scale of interest (e.g. the regional scale). Furthermore, methods often focus on single sectors and/or hazards, and only very few are able to reflect several sectors or multiple hazards. Process understanding and its use in cost assessment

    To summarize global research trends and activities on multimorbidity; then to assess the knowledge gaps and to identify implications for knowledge exchange between high income countries (HICs) and low- and middle- income countries (LMICs). A comprehensive search was conducted to identify research publications on multimorbidity in the Web of Science TM , as well as diabetes, depression, hypertension, and Chronic Obstructive Pulmonary Disease (COPD). The time frame for the search was from 1900 to June, 2016. Information (such as publication date, subject category, author, country of origin, title, abstract, and keywords) were extracted and the full texts were obtained for the co-citation analysis. Data were linked with the life expectancy at birth (years) and Gross National Income (GNI). Co-citation and hierarchal clustering analysis was used to map the trends and research networks with CiteSpace II (JAVA freeware, copyright Chaomei Chen, http://cluster.cis.drexel.edu/~cchen/citespace/). We identified 2864 relevant publications as at June 2016, with the first paper on this topic indexed in 1974 from Germany, but 80% were published after 2010. Further analysis yielded two knowledge gaps: (1) compared with single conditions (diabetes, hypertension, depression, and COPD), there is a mismatch between the high prevalence of multimorbidity and its research outputs (ratio of articles on multimorbidity vs other four single conditions is 1:13-150); (2) although a total of 76 countries have contributed to this research area, only 5% of research originated from LMICs where 73% of non-communicable disease (NCD) related deaths had occurred. Additional analysis showed the median year of first publication occurred 15 years later in the LMICs compared with HICs (2010 vs 1995); and longer life expectancy was associated with exponentially higher publication outputs (Pearson correlation coefficient r  = 0.95) at the global level. The life expectancy at the median year (1994) of

  7. Factors responsible for the stability and the existence of a clean energy gap of a silicon nanocluster

    We present a critical theoretical study of electronic properties of silicon nanoclusters, in particular the roles played by symmetry, relaxation, and hydrogen passivation on the stability, the gap states and the energy gap of the system using the order N [O(N)] nonorthogonal tight-binding molecular dynamics and the local analysis of electronic structure. We find that for an unrelaxed cluster with its atoms occupying the regular tetrahedral network, the presence of undistorted local bonding configuration is sufficient for the appearance of a small clean energy gap. However, the energy gap of the unrelaxed cluster does not start at the highest occupied molecular orbital (HOMO). In fact, between the HOMO and the lower edge of the energy gap, localized dangling bond states are found. With hydrogen passivation, the localized dangling bond states are eliminated, resulting in a wider and clean energy gap. Relaxation of these hydrogen passivated clusters does not alter either the structure or the energy gap appreciably. However, if the silicon clusters are allowed to relax first, the majority of the dangling bonds are eliminated but additional defect states due to bond distortion appear, making the energy gap dirty. Hydrogen passivation of these relaxed clusters will further eliminate most of the remnant dangling bonds but no appreciable effect on the defect states associated with bond distortions will take place, thus still resulting in a dirty gap. For the hydrogen-passivated Si N nanoclusters with no bond distortion and no overall symmetry, we have studied the variation of the energy gap as a function of size of the cluster for N in the range of 80< N<6000. The dependence of the energy gap on the size shows similar behavior to that for silicon nanoclusters with no bond distortion but possessing overall symmetry

  8. Knowledge diffusion in social work: a new approach to bridging the gap.

    The continuing gap between research and practice has long been a problem in social work. A great deal of the empirical practice literature has emphasized practice evaluation (usually in the form of single-case methodologies) at the expense of research dissemination and utilization. An alternative focus for social work researchers can be found in the extensive theoretical and research literature on knowledge diffusion, technology transfer, and social marketing. Knowledge diffusion and social marketing theory is explored in terms of its relevance to social work education and practice, including a consideration of issues of culture and power. The authors present an integrated dissemination model for social work and use a case example to illustrate the practical application of the model. The OPTIONS (OutPatient Treatment In ONtario Services) project is an example of the effective dissemination of two research-based addiction treatment modalities to nearly 1,000 direct practice clinicians in Ontario, Canada.

  9. Closing the gap between knowledge and clinical application: challenges for genomic translation.

    2015-01-01

    Despite early predictions and rapid progress in research, the introduction of personal genomics into clinical practice has been slow. Several factors contribute to this translational gap between knowledge and clinical application. The evidence available to support genetic test use is often limited, and implementation of new testing programs can be challenging. In addition, the heterogeneity of genomic risk information points to the need for strategies to select and deliver the information most appropriate for particular clinical needs. Accomplishing these tasks also requires recognition that some expectations for personal genomics are unrealistic, notably expectations concerning the clinical utility of genomic risk assessment for common complex diseases. Efforts are needed to improve the body of evidence addressing clinical outcomes for genomics, apply implementation science to personal genomics, and develop realistic goals for genomic risk assessment. In addition, translational research should emphasize the broader benefits of genomic knowledge, including applications of genomic research that provide clinical benefit outside the context of personal genomic risk.

    2010-02-26

    Expert opinion was canvassed to identify crucial knowledge gaps in current understanding of climate change impacts on coral reef fishes. Scientists that had published three or more papers on the effects of climate and environmental factors on reef fishes were invited to submit five questions that, if addressed, would improve our understanding of climate change effects on coral reef fishes. Thirty-three scientists provided 155 questions, and 32 scientists scored these questions in terms of: (i) identifying a knowledge gap, (ii) achievability, (iii) applicability to a broad spectrum of species and reef habitats, and (iv) priority. Forty-two per cent of the questions related to habitat associations and community dynamics of fish, reflecting the established effects and immediate concern relating to climate-induced coral loss and habitat degradation. However, there were also questions on fish demographics, physiology, behaviour and management, all of which could be potentially affected by climate change. Irrespective of their individual expertise and background, scientists scored questions from different topics similarly, suggesting limited bias and recognition of a need for greater interdisciplinary and collaborative research. Presented here are the 53 highest-scoring unique questions. These questions should act as a guide for future research, providing a basis for better assessment and management of climate change impacts on coral reefs and associated fish communities.

    The aim of this article is to present an overview of salient issues of exposure, characterisation and hazard assessment of nanomaterials as they emerged from the consensus-building of experts undertaken within the four year European Commission coordination project NanoImpactNet. The approach adopted is to consolidate and condense the findings and problem-identification in such a way as to identify knowledge-gaps and generate a set of interim recommendations of use to industry, regulators, research bodies and funders. The categories of recommendation arising from the consensual view address: significant gaps in vital factual knowledge of exposure, characterisation and hazards; the development, dissemination and standardisation of appropriate laboratory protocols; address a wide range of technical issues in establishing an adequate risk assessment platform; the more efficient and coordinated gathering of basic data; greater inter-organisational cooperation; regulatory harmonization; the wider use of the life-cycle approaches; and the wider involvement of all stakeholders in the discussion and solution-finding efforts for nanosafety.

    Full Text Available Modified vaccinia virus Ankara (MVA is the vector of choice for human and veterinary applications due to its strong safety profile and immunogenicity in vivo. The use of MVA and MVA-vectored vaccines against human and animal diseases must comply with regulatory requirements as they pertain to environmental risk assessment, particularly the characterization of potential adverse effects to humans, animals and the environment. MVA and recombinant MVA are widely believed to pose low or negligible risk to ecosystem health. However, key aspects of MVA biology require further research in order to provide data needed to evaluate the potential risks that may occur due to the use of MVA and MVA-vectored vaccines. The purpose of this paper is to identify knowledge gaps in the biology of MVA and recombinant MVA that are of relevance to its hazard characterization and discuss ongoing and future experiments aimed at providing data necessary to fill in the knowledge gaps. In addition, we presented arguments for the inclusion of uncertainty analysis and experimental investigation of verifiable worst-case scenarios in the environmental risk assessment of MVA and recombinant MVA. These will contribute to improved risk assessment of MVA and recombinant MVA vaccines.

    There is general agreement among scientists that global temperatures are rising and will continue to increase in the future. It is also agreed that human activities are the most important causes of these climatic variations, and that water resources are already suffering and will continue to be greatly impaired as a consequence of these changes. In particular, it is probable that areas with limited water resources will expand and that an increase of global water demand will occur, estimated to be around 35-60% by 2025 as a consequence of population growth and the competing needs of water uses. This will cause a growing imbalance between water demand (including the needs of nature) and supply. This urgency demands that climate change impacts on water be evaluated in different sectors using a cross-cutting approach (Contestabile in Nat Clim Chang 3:11-12, 2013). These issues were examined by the EU FP7-funded Co-ordination and support action "ClimateWater" (bridging the gap between adaptation strategies of climate change impacts and European water policies). The project studied adaptation strategies to minimize the water-related consequences of climate change and assessed how these strategies should be taken into consideration by European policies. This article emphasizes that knowledge gaps still exist about the direct effects of climate change on water bodies and their indirect impacts on production areas that employ large amounts of water (e.g., agriculture). Some sectors, such as ecohydrology and alternative sewage treatment technologies, could represent a powerful tool to mitigate climate change impacts. Research needs in these still novel fields are summarized.

    The data overload has created a new set of challenges in finding meaningful and relevant information with minimal cognitive effort. However designing robust and scalable knowledge discovery systems remains a challenge. Recent innovations in the (biological) literature mining tools have opened new avenues to understand the confluence of various diseases, genes, risk factors as well as biological processes in bridging the gaps between the massive amounts of scientific data and harvesting useful knowledge. In this paper, we highlight some of the findings using a text analytics tool, called ARIANA--Adaptive Robust and Integrative Analysis for finding Novel Associations. Empirical study using ARIANA reveals knowledge discovery instances that illustrate the efficacy of such tool. For example, ARIANA can capture the connection between the drug hexamethonium and pulmonary inflammation and fibrosis that caused the tragic death of a healthy volunteer in a 2001 John Hopkins asthma study, even though the abstract of the study was not part of the semantic model. An integrated system, such as ARIANA, could assist the human expert in exploratory literature search by bringing forward hidden associations, promoting data reuse and knowledge discovery as well as stimulating interdisciplinary projects by connecting information across the disciplines.

    1993-06-01

    This study, carried out during August-October, 1991, involved 236 respondents to a questionnaire designed to determine awareness and attitudes to AIDS and the consequent effect of such awareness on their sexual behaviour. Almost all the medical students were aware of the existence of the disease, while a few (3.8 per cent) of the non-medicos believed that it had not yet reached Nigeria. Most students i.e. 98 per cent and 97 per cent of these respective groups were aware of carrier state of the disease. Only a small percentage of students, mostly medics knew about the exact signs and symptoms of clinical AIDS. The level of knowledge about the modes of transmission of AIDS was found to be adequate. With regard to the effect of this awareness on their behaviour, it was known that a good number of medics (30.37) per cent and non-medics (28.88) per cent had started using condoms. About 40 per cent medicos, and 45 per cent non-medicos revealed an aversion to sit near a person with AIDS thus emphasizing the stigma associated with the disease. Regarding control of AIDS, many felt there should be strict isolation of HIV positive individuals along with a ban on prostitution and homosexuality.

  18. Gaps in knowledge: tracking and explaining gender differences in health information seeking.

    2015-03-01

    Self-directed health information seeking has become increasingly common in recent years, yet there is a substantial body of evidence suggesting that females are more likely to engage in information seeking than males. Previous research has largely ignored the significance of this difference as both an empirical and a theoretical finding. The current study has two goals, seeking to track this sex gap over time and to test explanations for its existence. The three explanations tested are based in past findings of gendered division of childcare labor, gendered reactivity to illness, and gendered perceived risk of illness. These were tested using multiple dependent variables from both repeated cross sectional data and 2012 data from the Health Information Trends Survey (HINTS). Results show that females are significantly more likely to look for cancer information, information in general, and information over the Internet over time than males, though the gap may be closing in the case of cancer information. The three explanations also received little clear support though perceived risk of getting cancer acted as a mediator through which men may be less likely to look for cancer information. Based on this analysis it is clear that a sex gap in information seeking is present and theories of masculinity and health may hold promise in some contexts but additional explanations are needed.

    Full Text Available Researchers studying processes of global environmental change are increasingly interested in their work having impacts that go beyond academia to influence policy and management. Recent scholarship in the conservation sciences has pointed to the existence of a research-action gap and has proposed various solutions for overcoming it. However, most of these studies have been limited to the spaces of dissemination, where the science has already been done and is then to be passed over to users of the information. Much less attention has been paid to encounters that occur between scientists and nonscientists during the practice of doing scientific research, especially in situations that include everyday roles of labor and styles of communication (i.e., fieldwork. This paper builds on theories of contact that have examined encounters and relations between different groups and cultures in diverse settings. I use quantitative and qualitative evidence from Madidi National Park, Bolivia, including an analysis of past research in the protected area, as well as interviews (N = 137 and workshops and focus groups (N = 12 with local inhabitants, scientists, and park guards. The study demonstrates the significance of currently unacknowledged or undervalued components of the research-action gap, such as power, respect, and recognition, to develop a relational and reciprocal notion of impact. I explain why, within such spaces of encounter or misencounter between scientists and local people, knowledge can be exchanged or hidden away, worldviews can be expanded or further entrenched, and scientific research can be welcomed or rejected.

    A survey was conducted among freshly passed undergraduate doctors of a medical college in Eastern India with the aim to investigate their exposure to oncology patients, their knowledge about various aspects of oncology patient management and their confidence in managing patients with cancer. One hundred and twelve newly passed interns of a Government Medical College in Kolkata were interviewed using semi-structured partly open ended and partly closed end questionnaire. The questionnaire dealt with the qualitative and quantitative aspects of knowledge and perception of the interns about the problem of cancer and its management. A total of 82 interns responded to the questionnaire, with a response rate of 73.2%. About 53% of the respondents have seen less than five patients during their undergraduate ward/clinical postings. Among the respondents, 71% felt they were confident in diagnosing cancer, and about 56% were confident in counseling of patient and their relatives about cancer. About 63% were aware about the role of surgery; however, only 32% and 37.5% were aware about the role of radiotherapy and chemotherapy, respectively. A dismal 12.5% were confident of care of terminal and late stage patients. Preparedness was correlated with exposure to patients with cancer (P = 0.03). Majority (87%) felt the need for incorporating oncology training at the undergraduate level and the most frequent method (67%) suggested for doing so was having separate posting in radiotherapy department/oncology wards. There is glaring knowledge gap among newly passed doctors and integrated oncology postings during undergraduate training and during internship may help seal this gap.

  2. Crowdsourcing awareness: exploration of the ovarian cancer knowledge gap through Amazon Mechanical Turk.

    Directory of Open Access Journals (Sweden)

    Rebecca R Carter

    Full Text Available BACKGROUND: Ovarian cancer is the most lethal gynecologic disease in the United States, with more women dying from this cancer than all gynecological cancers combined. Ovarian cancer has been termed the "silent killer" because some patients do not show clear symptoms at an early stage. Currently, there is a lack of approved and effective early diagnostic tools for ovarian cancer. There is also an apparent severe knowledge gap of ovarian cancer in general and of its indicative symptoms among both public and many health professionals. These factors have significantly contributed to the late stage diagnosis of most ovarian cancer patients (63% are diagnosed at Stage III or above, where the 5-year survival rate is less than 30%. The paucity of knowledge concerning ovarian cancer in the United States is unknown. METHODS: The present investigation examined current public awareness and knowledge about ovarian cancer. The study implemented design strategies to develop an unbiased survey with quality control measures, including the modern application of multiple statistical analyses. The survey assessed a reasonable proxy of the US population by crowdsourcing participants through the online task marketplace Amazon Mechanical Turk, at a highly condensed rate of cost and time compared to traditional recruitment methods. CONCLUSION: Knowledge of ovarian cancer was compared to that of breast cancer using repeated measures, bias control and other quality control measures in the survey design. Analyses included multinomial logistic regression and categorical data analysis procedures such as correspondence analysis, among other statistics. We confirmed the relatively poor public knowledge of ovarian cancer among the US population. The simple, yet novel design should set an example for designing surveys to obtain quality data via Amazon Mechanical Turk with the associated analyses.

    The aim of this review was to consolidate and synthesize existing evidence regarding current knowledge and awareness of the Canadian Physical Activity (PA) and Sedentary Behaviour (SB) Guidelines. MEDLINE, Embase, and PsycINFO were searched for peer-reviewed publications pertaining to the guidelines. Content experts, key organizations (i.e., ParticipACTION and the Canadian Fitness and Lifestyle Research Institute), journal Web sites, and service organizations (i.e., the Canadian Society for Exercise Physiology (CSEP) and the Public Health Agency of Canada) were consulted for additional evidence. Scientific publications (n = 6) and research from ParticipACTION and the Canadian Fitness and Lifestyle Research Institute reported that awareness of the guidelines is low, especially with respect to the SB guidelines. Less than 10% of survey respondents from the Canadian population were aware of the PA guidelines, and less than 5% were aware of the SB guidelines. Information on the guidelines was available on 51% of public health unit and CSEP partner Web sites. Online metrics (e.g., downloads, site accessions) from CSEP, the Public Health Agency of Canada, and journal Web sites showed that online accession of the guidelines was high (e.g., all "highly accessed" on journal Web sites). This review showed that awareness of the Canadian PA and SB Guidelines is low among the general population but higher among the scientific and stakeholder communities. Governmental, nongovernmental, and stakeholder organizations should collaborate in creating sustained, long-term, and well-resourced communication plans to reach the Canadian population to raise awareness of PA and SB guidelines and should implement programs to facilitate their uptake.

    2017-10-01

    Exposure to soil or water contaminated with the urine of Leptospira -infected animals is the most common way in which humans contract leptospirosis. Entire populations can be at high risk of leptospirosis while working in inundated fields, when engaging in aquatic sports, or after periods of heavy rainfall. The risk of infection after contact with these environmental sources depends on the ability of Leptospira bacteria to survive, persist, and infect new hosts. Multiple variables such as soil and water pH, temperature, and even environmental microbial communities are likely to shape the environmental conditions needed by the pathogen to persist.

    Schmalbach, Cecelia E

    2016-07-01

    Current otolaryngology literature and future scientific direction rely heavily on a rigorous peer review process. Just as manuscripts warrant thoughtful review with constructive feedback to the authors, the same can be said for critiques written by novice peer reviewers. Formal scientific peer review training programs are lacking. Recognizing this knowledge gap, Otolaryngology-Head and Neck Surgery is excited to offer its new Resident Reviewer Development Program. All otolaryngology residents who are postgraduate year 2 and above and in excellent academic standing are eligible to participate in this mentored program, during which they will conduct 6 manuscript reviews under the direction of a seasoned reviewer in his or her subspecialty area of interest. By completing reviews alongside a mentor, participants gain the required skills to master the peer review process-a first step that often leads to journal editorial board and associate editor invitations. © American Academy of Otolaryngology—Head and Neck Surgery Foundation 2016.

    The Mars Program Planning Group (MPPG) was an agency wide effort, chartered in March 2012 by the NASA Associate Administrator for Science, in collaboration with NASA's Associate Administrator for Human Exploration and Operations, the Chief Scientist, and the Chief Technologist. NASA tasked the MPPG to develop foundations for a program-level architecture for robotic exploration of Mars that is consistent with the President's challenge of sending humans to the Mars system in the decade of the 2030s and responsive to the primary scientific goals of the 2011 NRC Decadal Survey for Planetary Science. The Mars Exploration Program Analysis Group (MEPAG) also sponsored a Precursor measurement Strategy Analysis Group (P-SAG) to revisit prior assessments of required precursor measurements for the human exploration of Mars. This paper will discuss the key results of the MPPG and P-SAG efforts to update and refine our understanding of the Strategic Knowledge Gaps (SKGs) required to successfully conduct human Mars missions.

    Despite media interest in alleged sexual violence and harassment in the UK military, there remains a paucity of UK-based peer-reviewed research in this area. Ministry of Defence and service-specific reports support the suggestion that UK service personnel may be at risk of experiencing sexual harassment. These reports however highlight a reluctance by service personnel to report sexual harassment through official channels. In this article, we discuss the paucity of UK-based research pertaining to the prevalence and impact of sexual harassment in the military, explore potential reasons for this gap in knowledge and outline future directions and priorities for academic research. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    To prevent onset of age-related diseases and physical and cognitive decline, interventions to slow human aging and extend health span must eventually be applied to people while they are still young and healthy. Yet most human aging research examines older adults, many with chronic disease, and little is known about aging in healthy young humans. This article explains how this knowledge gap is a barrier to extending health span and puts forward the case that geroscience should invest in researching the pace of aging in young adults. As one illustrative example, we describe an initial effort to study the pace of aging in a young-adult birth cohort by using repeated waves of biomarkers collected across the third and fourth decades to quantify the pace of coordinated physiological deterioration across multiple organ systems (eg, pulmonary, periodontal, cardiovascular, renal, hepatic, metabolic, and immune function). Findings provided proof of principle that it is possible to quantify individual variation in the pace of aging in young adults still free of age-related diseases. This article articulates research needs to improve longitudinal measurement of the pace of aging in young people, to pinpoint factors that slow or speed the pace of aging, to compare pace of aging against genomic clocks, to explain slow-aging young adults, and to apply pace of aging in preventive clinical trials of antiaging therapies. This article puts forward a research agenda to fill the knowledge gap concerning lifelong causes of aging. © The Author 2016.

    Although South Asians are at higher risk for coronary heart disease (CHD) than most other U.S. racial/ethnic groups, very little research has addressed this disparity. As a first step in developing culturally targeted CHD prevention messages for this rapidly growing community, this study examined South Asians' knowledge and beliefs about CHD. Analyses, conducted in 2009, were based on data collected from January to July 2008 in a cross-sectional study population of 270 South Asian adults in Illinois. Interviews were conducted in English, Hindi, or Urdu using a standardized questionnaire. Multivariate regression models were used to examine the associations between sociodemographics and CHD knowledge and attitudes about preventability. Eighty-one percent of respondents had one or more CHD risk factors. Most participants (89%) said they knew little or nothing about CHD. Stress was the most frequently mentioned risk factor (44%). Few mentioned controlling blood pressure (11%); cholesterol (10%); and diabetes (5%) for prevention. Fifty-three percent said that heart attacks are not preventable. Low education level, being interviewed in Urdu or Hindi, and low level of acculturation were associated with less knowledge and believing that CHD is not preventable. A majority of South Asians in this study believed that CHD is not preventable and had low awareness of modifiable risk factors. As a first step, CHD education should target the knowledge gaps that may affect risk factor control and behavior change. Educational messages may need to be somewhat different for subgroups (e.g., by education and language) to be maximally effective. 2010 American Journal of Preventive Medicine.

    The scarcity of familial hypercholesterolemia (FH) cases reported in Saudi Arabia might be indicative of a lack of awareness of this common genetic disease among physicians. To assess physicians' awareness, practice, and knowledge of FH in Saudi Arabia. This is a cross-sectional study conducted among physicians at four tertiary hospitals in Riyadh, Saudi Arabia between March 2016 and May 2016 using a self-administered questionnaire. A total of 294 physicians completed the survey (response rate 90.1%). Overall, 92.9% of the participants have poor knowledge of FH while only 7.1% have acceptable knowledge. The majority (68.7%) of physicians rated their familiarity with FH as average or above average, and these had higher mean knowledge scores than participants with self-reported below average familiarity (mean 3.4 versus 2.6) (P knowledge scores compared to those without FH patients in their care (3.5 versus 2.9) (P = 0.006). In addition, there were statistically significant differences between physicians' mean knowledge scores and their ages, levels of training, and years in practice. Moreover, a substantial deficit was identified in the awareness of various clinical algorithms to diagnose patients with FH, cascade screening, specialist lipid services, and the existence of statin alternatives, such as proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors. A substantial deficit was found in the awareness, knowledge, practice, and detection of FH among physicians in Saudi Arabia. Extensive educational programs are required to raise physician awareness and implement best practices; only then can the impact of these interventions on FH management and patient outcome be assessed.

    The unprecedented threats to the health and sustainability of wildlife populations are inspiring conversations on the need to change the way knowledge is generated, valued, and used to promote action to protect wildlife health. Wildlife Health 2.0 symbolizes the need to investigate how to improve connections between research expertise and policy or practices to protect wildlife health. Two imperatives drive this evolution: 1) growing frustrations that research is inadequately being used to inform management decisions and 2) the realization that scientific certainty is context specific for complex socioecologic issues, such as wildlife health. Failure to appreciate the unpredictability of complex systems or to incorporate ethical and cultural dimensions of decisions has limited the contribution of research to decision making. Wildlife health can draw from scholarship in other fields, such as public health and conservation, to bridge the knowledge-to-action gap. Efforts to integrate science into decisions are more likely to be effective when they enhance relevance, credibility, and legitimacy of information for people who will make or be affected by management decisions. A Wildlife Health 2.0 agenda is not a rejection of the current research paradigm but rather a call to expand our areas of inquiry to ensure that the additional contextual understanding is generated to help decision makers make good choices.

    Recently, graphene family materials (GFMs) have been introduced among all fields of science and still get numerous attention. Also, the applicability of these materials in many areas makes them very attractive. GFMs have attracted both academic and industrial interest as they can produce a dramatic improvement in materials properties at very low filler content. The aim of this review is to identify, summarize, and present the first available information on the influence of GFMs on soil and water environment as well as identify the knowledge gaps and indicate the directions for the next generation of the original scientific investigations. The paper also presents our first preliminary impact assessment and potential pathways of GFMs distribution in the environment. We used as an example the reduced graphene oxide/Al 2 O 3 nanocomposite (RGO/Al 2 O 3 ) that has been previously designed and synthesized by us. Authors believe that further work should focus on improvement of characterization methodology applicable for ecotoxicity analyses and possible interactions between GFMs and different living ecosystems. Consequently, the potential impact of graphene and its derivatives on environmental health is a matter of academic interest. However, potential hazards sufficient for risk assessment and concerned with GFMs usage in consumer products first need to be investigated and identified. Further research should focus on gathering knowledge on GFMs properties for life cycle analyses, which still poses a great challenge for scientists

    Despite opportunities for didactic education on obesity management, we still observe low rates of weight management visits in our primary care setting. This paper describes the co-creation by front-line interdisciplinary health care providers and researchers of the 5As Team intervention to improve obesity prevention and management in primary care. We describe the theoretical foundations, design, and core elements of the 5AsT intervention, and the process of eliciting practitioners' self-identified knowledge gaps to inform the curricula for the 5AsT intervention. Themes and topics were identified through facilitated group discussion and a curriculum relevant to this group of practitioners was developed and delivered in a series of 12 workshops. The research question and approach were co-created with the clinical leadership of the PCN; the PCN committed internal resources and a practice facilitator to the effort. Practice facilitation and learning collaboratives were used in the intervention For the content, front-line providers identified 43 topics, related to 13 themes around obesity assessment and management for which they felt the need for further education and training. These needs included: cultural identity and body image, emotional and mental health, motivation, setting goals, managing expectations, weight-bias, caregiver fatigue, clinic dynamics and team-based care, greater understanding of physiology and the use of a systematic framework for obesity assessment (the "4Ms" of obesity). The content of the 12 intervention sessions were designed based on these themes. There was a strong innovation values fit with the 5AsT intervention, and providers were more comfortable with obesity management following the intervention. The 5AsT intervention, including videos, resources and tools, has been compiled for use by clinical teams and is available online at http://www.obesitynetwork.ca/5As_Team .

    2002-01-01

    The Northern Climate ExChange (NCE) Gap Analysis Project was launched in 1999 with an objective to assess the state of knowledge on climate change in northern Canada. Resulting products of the project have included the Infosource Database, an on-line database of published climate change research related to the Canadian North, the Directory of Contacts, another on-line database of interested parties to climate change issues, and a set of tables that rate the level of available information on climate change as it relates to natural, economic and community systems. Other products include a report of a workshop on climate change research, 2 reports assessing the level of traditional northern knowledge about climate change, 2 reports assessing the completeness and value of the Infosource Database, a web site for NCE, and this report. All products are available to the public on the Internet or on a CD-ROM. The NCE Gap Analysis Project has shown there are inequalities in the amount of information across different systems, and that there is more knowledge on predicted temperature changes than for other climate components. The study notes that there are strong regional trends for compiled knowledge, with some regions having been better studied than others. The project revealed that traditional knowledge of climate change has not been well documented, and that more information exists about climate change impacts on biological systems with an economic component than those without economic significance. refs., tabs., figs

  20. Existence of a miscibility gap in the U-Nd-O ternary system and its relationship with the HBS of irradiated nuclear fuel

    International Nuclear Information System (INIS)

    Dottavio, Giannina

    2014-01-01

    Today, the most used nuclear fuel in pressurized water reactors operating in French power plants is uranium dioxide UO 2 . Under irradiation, this ceramic undergoes many modifications, a very interesting one is the incorporation of fission products (Nd,Ce,Eu..) in the crystallographic structure of the fuel. In this thesis, we focused on the modifications of the crystallographic structures of the fuel caused by fission product incorporation. In order to achieve this objective, we conceived a plan formed by steps of increasing complexity and involving two types of materials: non irradiated nuclear fuel (U 1-y Nd y )O 2 (neodymium is the most abundant cationic fission product), and highly irradiated UO 2 fuels. Firstly, we have studied the evolution of crystallographic structure of a sample (U 1-y Nd y )O 2 during an annealing treatment. The results allowed us to confirm a previous hypothesis formulated in the group suggesting that Nd is not totally soluble in UO 2 , as traditionally considered. Instead of that, there is a miscibility gap in the ternary system U-Nd-O. Afterwards, we have characterized this miscibility gap, determining its tie-lines by means of two approaches: a) experimentally, by means of XRD measurements, to estimate the chemical composition of both phases in the biphasic samples, b) theoretically, by means of the thermodynamic assessment of the phase diagram U-Nd-O by the CALPHAD method, including for the assessment the tie-lines previously calculated for our samples, in order to determine the tie-lines for all composition and temperatures of this miscibility gap. We have also distinguished many others systems (U,L)O 2 (U,L,L')O 2 , in which 'L' means lanthanides or actinides existing in the irradiated fuel, that exhibit a miscibility gap. As a consequence, we formulated the hypothesis that a miscibility gap could also exist in the irradiated fuel, which could be, consequently, considered as a pseudo phase diagram U-PF-O (PF

    Mycoplasma hyopneumoniae (M. hyopneumoniae) is the primary pathogen of enzootic pneumonia, a chronic respiratory disease in pigs. Infections occur worldwide and cause major economic losses to the pig industry. The present paper reviews the current knowledge on M. hyopneumoniae infections, with emphasis on identification and analysis of knowledge gaps for optimizing control of the disease. Close contact between infected and susceptible pigs is the main route of M. hyopneumoniae transmission. Management and housing conditions predisposing for infection or disease are known, but further research is needed to better understand M. hyopneumoniae transmission patterns in modern pig production systems, and to assess the importance of the breeding population for downstream disease control. The organism is primarily found on the mucosal surface of the trachea, bronchi and bronchioles. Different adhesins and lipoproteins are involved in the adherence process. However, a clear picture of the virulence and pathogenicity of M. hyopneumoniae is still missing. The role of glycerol metabolism, myoinositol metabolism and the Mycoplasma Ig binding protein-Mycoplasma Ig protease system should be further investigated for their contribution to virulence. The destruction of the mucociliary apparatus, together with modulating the immune response, enhances the susceptibility of infected pigs to secondary pathogens. Clinical signs and severity of lesions depend on different factors, such as management, environmental conditions and likely also M. hyopneumoniae strain. The potential impact of strain variability on disease severity is not well defined. Diagnostics could be improved by developing tests that may detect virulent strains, by improving sampling in live animals and by designing ELISAs allowing discrimination between infected and vaccinated pigs. The currently available vaccines are often cost-efficient, but the ongoing research on developing new vaccines that confer protective

    In 2007, the State of Hawaii, Healthy Hawaii Initiative conducted a statewide social-marketing campaign promoting increased physical activity and nutrition. The campaign included substantial formative research to develop messages tailored for Hawaii's multiethnic Asian and Pacific Islander populations. The authors conducted a statewide random digital dialing telephone survey to assess the campaign's comparative reach among individuals with different ethnicities and different levels of education and income. This analysis suggests that the intervention was successful in reaching its target ethnic audiences. However, a knowledge gap related to the campaign appeared among individuals with incomes less than 130% of the poverty level and those with less than a high school education. These results varied significantly by message and the communication channel used. Recall of supermarket-based messages was significantly higher among individuals below 130% of the poverty level and those between 18 and 35 years of age, 2 groups that showed consistently lower recall of messages in other channels. Results suggest that cultural tailoring for ethnic audiences, although important, is insufficient for reaching low-income populations, and that broad-based social marketing campaigns should consider addressing socioeconomic status-related channel preferences in formative research and campaign design.

    Full Text Available The effectiveness of marine protected areas (MPAs and the conservation of marine environments must be based on reliable information on the quality of the marine environment that can be obtained in a reasonable timeframe. We reviewed studies that evaluated all aspects related to the effectiveness of MPAs in order to describe how the studies were conducted and to detect fields in which research is lacking. Existing parameters used to evaluate the effectiveness of MPAs are summarised. Two-hundred and twenty-two publications were reviewed. We identified the most commonly used study subjects and methodological approaches. Most of the studies concentrated on biological parameters. Peer reviewed studies were based on control vs. impact design. BACI and mBACI designs were used in very few studies. Through this review, we have identified gaps in the objectives assigned to MPAs and the way in which they have been evaluated. We suggest some guidelines aimedat improving the assessment of the effects of protection in MPAs.

  5. Melanoma reporting to central cancer registries by US dermatologists: an analysis of the persistent knowledge and practice gap.

    2011-11-01

    Every state requires diagnosing physicians to report new cases of melanoma to its central cancer registry. Previous regional studies and anecdotal experience suggest that few dermatologists are cognizant of this obligation. This oversight could result in a large number of unreported melanomas annually and, in turn, US melanoma statistics that markedly underestimate the true incidence of the disease. We sought to quantify the percentage of dermatologists who are unaware of melanoma reporting requirements (the knowledge gap) and who are not reporting melanoma diagnoses (the practice gap). We also sought to delineate factors predictive of reporting knowledge and behavior. A survey was administered to attendees of the Cutaneous Oncology Symposium at the 2010 American Academy of Dermatology annual meeting. In all, 104 of 419 eligible attendees completed surveys (response rate 26%). Fifty percent of respondents do not believe they are required to report melanomas and 56% do not actively report their diagnoses to a registry. Practice duration of less than 10 years was significantly associated with both a knowledge gap (P = .047) and practice gap (P = .056). Similarly, dermatologists who diagnosed fewer than 10 melanomas per year were more likely to possess a knowledge gap (P = .096) and a practice gap (P = .087) than those who diagnosed more than 10. Limitations include small sample size and low response rate. A majority of dermatologists are not reporting melanomas they diagnose to a cancer registry, and half of those surveyed were not aware that diagnosing physicians are required to report melanoma.

    To date, greenhouse gas (GHG) emissions, mitigation strategies and the accompanying health co-benefits in different economic sectors have not been fully investigated. The purpose of this paper is to review comprehensively the evidence on GHG mitigation measures and the related health co-benefits, identify knowledge gaps, and provide recommendations to promote further development and implementation of climate change response policies. Evidence on GHG emissions, abatement measures and related health co-benefits has been observed at regional, national and global levels, involving both low- and high-income societies. GHG mitigation actions have mainly been taken in five sectors: energy generation, transport, food and agriculture, household and industry, consistent with the main sources of GHG emissions. GHGs and air pollutants to a large extent stem from the same sources and are inseparable in terms of their atmospheric evolution and effects on ecosystem; thus, GHG reductions are usually, although not always, estimated to have cost effective co-benefits for public health. Some integrated mitigation strategies involving multiple sectors, which tend to create greater health benefits. The pros and cons of different mitigation measures, issues with existing knowledge, priorities for research, and potential policy implications were also discussed. Findings from this study can play a role not only in motivating large GHG emitters to make decisive changes in GHG emissions, but also in facilitating cooperation at international, national and regional levels, to promote GHG mitigation policies that protect public health from climate change and air pollution simultaneously.

    2010-01-01

    Full Text Available Abstract Bracing is the main non-surgical intervention in the treatment of idiopathic scoliosis during growth, in hyperkyphosis (and Scheuermann disease and occasionally for spondylolisthesis; it can be used in adult scoliosis, in the elderly when pathological curves lead to a forward leaning posture or in adults after traumatic injuries. Bracing can be defined as the application of external corrective forces to the trunk; rigid supports or elastic bands can be used and braces can be custom-made or prefabricated. The state of research in the field of conservative treatment is insufficient and while it can be stated that there is some evidence to support bracing, we must also acknowledge that today we do not have a common and generally accepted knowledge base, and that instead, individual expertise still prevails, giving rise to different schools of thought on brace construction and principles of correction. The only way to improve the knowledge and understanding of brace type and brace function is to establish a single and comprehensive source of information about bracing. This is what the Scoliosis Journal is going to do through the "Brace Technology" Thematic Series, where technical papers coming from the different schools will be published.

    Pediatric hospitalists are increasingly involved in the clinical management of children with medical complexity (CMC), specifically those with neurologic impairment and technology dependence. Clinical care guidelines and educational resources on management of the diseases and devices prevalent in CMC are scarce. The objective of this study was to develop and evaluate a web-based curriculum on care of CMC for hospitalists at our institution using a novel approach to validate educational content. Junior faculty collaborated with senior hospitalist peer mentors to create multimedia learning modules on highly-desired topics as determined by needs assessment. Module authors were encouraged to work with subspecialty experts from within the institution and to submit their modules for external peer review. Pilot study participants were asked to complete all modules, associated knowledge tests, and evaluations over a 4-month period. Sixteen of 33 eligible hospitalists completed the curriculum and associated assessments. High scores with respect to satisfaction were seen across all modules. There was a significant increase in posttest knowledge scores (P < 0.001) with sustained retention at 6 months posttest (P < 0.013). Participants were most likely to make changes to their teaching and clinical practice based on participation in this curriculum. We used a novel approach for content development in this curriculum that incorporated consultation with experts and external peer review, resulting in improved knowledge, high satisfaction, and behavior change. Our approach may be a useful method to improve content validity for educational resources on topics that do not have established clinical care guidelines.

  9. Radioecological consequences of potential accident in Norwegian coastal waters. Uncertainties and knowledges gaps in methodology

    Complete text of publication follows. A potential accident involving the transport of spent nuclear fuel along the Norwegian coastline has been choosen for evaluation of a dose assessment methodology. The accident scenario assumes that the release the radioactivity takes place under water and that there is free exchange of water between the spent fuel and the sea. The inventory has been calculated using the ORIGEN programme. Radioecological consequences are provided by the NRPA compartment model which includes the processes of advection of radioactivity between compartments and water-sediment interactions. The contamination of biota is further calculated from the radionuclide concentrations in filtered seawater in the different water regions. Doses to man are calculated on the basis of radionuclide concentrations in marine organisms, water and sediment and dose conversion factors. Collective dose-rates to man, doses to the critical groups, concentration of radionuclides in biota/sea-foods and doses to marine organisms were calculated through the evaluation of radioecological consequences after accidents. Results of calculations indicate that concentrations of radionuclides for some marine organisms can exceed guideline levels. At the same time collective dose rates to man as well as doses to a critical group are not higher than guideline levels. Comparison of results from calculations with provisional benchmark values suggests that doses to biota are in most cases unlikely to be of concern. However, to some marine organisms can be much higher than the screening dose of 10 μGyh over long periods. It is apparent that water-sediment distribution coefficients and concentration factors constitute the main sources of uncertainties in the present case. It is important to note that knowledge gaps concerning the influence of relatively low dose to populations of marine organisms over long time periods (many generations) substantially constrain the accessor's ability to

    Full Text Available Background. The increasing prevalence of HIV in Uganda during the last decade (7.5% in 2004-05 to 8.3% in 2011 among women and 5.0% in 2004-05 to 6.1% among men in 2011 of 15 to 49 years clearly shows that women are disproportionately affected by HIV epidemic. Hence, we assessed the prevalence of HIV and focused on differences in risky sexual behaviour and knowledge of HIV among Ugandan youth. Design and Methods. Uganda AIDS Indicator Survey 2011 data was used. The total samples of men and women (15 to 24 years, interviewed and tested for HIV, were 3450 and 4504 respectively. The analysis of risky sexual behaviour was based on 1941 men and 3127 women who had ever had sex and were tested for HIV. Pearson’s Chi-square test and multivariate logistic regression analysis were used. Results. Findings showed that young women were almost two times more vulnerable than young men in acquiring HIV (OR=1.762, P<0.001. Women who had first sex under age 15 (7.3%, had more than 2 sexual partners (9.2% and did not use condom during last sex (6.4% were more HIV-positive. Higher risk was found among women (6.3% than men (2.2%. Significantly (P<0.01 less percentage (81.3% of women as compared to men (83.8% perceived that the probability of HIV transmission may be reduced by correct and consistent use of the condom during sex. Conclusions. Hence, there is an urgent need for effective strategies and programmes to raise awareness on sexual health and risky behaviour, particularly targeting the youth, which will reduce the gender gap in risky sexual behaviour and new transmission of HIV in Uganda.

    Radio transmitters and associated devices may induce negative effects that can bias the results of ongoing research. The main documented effects of radio transmitters on animals include reduced survival, decreased productivity, changes in behaviour and movement patterns and a biased sex ratio. The only factors that have claimed responsibility for these possible damages are the weight of the radio transmitter and associated devices, and the attachment type. The electromagnetic radiation produced by radio transmitters has not been considered so far in research. There have been no studies evaluating the effects of non-ionising electromagnetic radiation (radiofrequency signals) necessary for tracking, although the problems found were significantly associated with the length of time that animals had been carrying their radio transmitters. Similar problems as those in radiotracked animals have been found in numerous studies with animals exposed to radiofrequency radiation for a sufficient amount of time. Laboratory scientists investigating the orientation of animals know they have to shield the place where experiments are performed to prevent interference from man-made radiation, as anthropogenic signals may distort the results. It is paradoxical that, at the same time, field scientists investigating the movements and other aspects of animal biology are providing animals with radio transmitters that emit the same type of radiation, since this may affect the results concerning their orientation and movement. This paper identifies gaps in the knowledge that should be investigated in-depth. The possibility that the radiofrequency radiation from radiotracking devices is responsible for the findings should be considered. Considering this factor may allow researchers to best understand the long-term effects found. - Highlights: • Radiotracking may induce negative effects that can bias the results. • Effects have been documented on survival, reproduction and behaviour.

  13. Impacts of elevated atmospheric CO2 on forest trees and forest ecosystems: knowledge gaps

    2003-06-01

    Atmospheric CO 2 is rising rapidly, and options for slowing the CO 2 rise are politically charged as they largely require reductions in industrial CO 2 emissions for most developed countries. As forests cover some 43% of the Earth's surface, account for some 70% of terrestrial net primary production (NPP), and are being bartered for carbon mitigation, it is critically important that we continue to reduce the uncertainties about the impacts of elevated atmospheric CO 2 on forest tree growth, productivity, and forest ecosystem function. In this paper, 1 review knowledge gaps and research needs on the effects of elevated atmospheric CO 2 on forest above- and below-ground growth and productivity, carbon sequestration, nutrient cycling, water relations, wood quality, phonology, community dynamics and biodiversity, antioxidants and stress tolerance, interactions with air pollutants, heterotrophic interactions, and ecosystem functioning. Finally, 1 discuss research needs regarding modelling of the impacts of elevated atmospheric CO 2 on forests. Even though there has been a tremendous amount of research done with elevated CO 2 and forest trees, it remains difficult to predict future forest growth and productivity under elevated atmospheric CO 2 . Likewise, it is not easy to predict how forest ecosystem processes will respond to enriched CO 2 . The more we study the impacts of increasing CO 2 , the more we realize that tree and forest responses are yet largely uncertain due to differences in responsiveness by species, genotype, and functional group, and the complex interactions of elevated atmospheric CO 2 with soil fertility, drought, pests, and co-occurring atmospheric pollutants such as nitrogen deposition and O 3 . Furthermore, it is impossible to predict ecosystem-level responses based on short-term studies of young trees grown without interacting stresses and in small spaces without the element of competition.

    Full Text Available The psychological contract has received substantial theoretical attention over the past two decades as a popular framework within which to examine contemporary employment relationships. Previous research mostly examines breach and violation of the psychological contract and its impact on employee organization outcomes. Few studies have employed longitudinal, prospective research designs to investigate the psychological contract and as a result, psychological contract content and formation are incompletely understood. It is argued that employment relationships may be better proactively managed with greater understanding of formation and changes in the psychological contract. We examine existing psychological contract literature to identify five key factors proposed to contribute to the formation of psychological contracts. We extend the current research by integrating these factors for the first time into a temporal model of psychological contract development.

    The report summarizes the state of knowledge for various renovation measures of apartment buildings built between 1941-1980. The renovation potential is estimated to give half the energy use for heating and hot water. This efficiency improvement is considered possible, but not likely. There are many case studies of individual projects with theoretical calculations of renovation potential for different measures. There are relatively many general studies of the housing stock in general where the potential for various measures have been calculated for the whole of Sweden, but few studies of actual projects completed. Binding minimum requirements related to the Energy Performance of Buildings Directive (EPBD) for buildings for renovation has been introduced in several other countries in the EU which is also found to contribute to more energy-efficient measures introduced in major renovation projects. The key measures that we have found is the introduction of FTX system, renovation of the building envelope as well as individual metering and billing of heating and hot water.

    Dry eye, a common yet underrecognized and evolving field, has few recommended treatment algorithms, mostly based on expert consensus rather than robust research evidence. There are high costs associated with managing dry eye and conducting research to identify effective and safe long-term treatments. To support evidence-based management of dry eye, our purpose was to identify and prioritize important clinical research questions for future clinical research. We translated recommendations from the American Academy of Ophthalmology's 2013 Preferred Practice Patterns for dry eye into answerable clinical research questions about treatment effectiveness. Clinicians around the world who manage patients with dry eye rated each question's importance from 0 (not important) to 10 (very important) using a 2-round online Delphi survey. We considered questions as "important" if ≥75% of respondents assigned a rating of 6 or more in round 2. We mapped the identified important clinical research questions to reliable systematic reviews published up to March 2016. Seventy-five clinicians from at least 21 countries completed both Delphi rounds. Among the 58 questions, 24 met our definition of "important": 9/24 and 7/24 addressed topical and systemic treatments, respectively. All 4 questions with the highest 25th percentiles addressed topical treatments. Although 6/24 "important" questions were associated with 4 existing reliable systematic reviews, none of these reviews came to a definitive conclusion about treatment effectiveness. We identified gaps pertaining to treatment options for dry eye. Future clinical research on the management of dry eye should strongly consider these prioritized questions.

    A review on concentration factors (CF) for the marine environment was conducted in order to consider the relevance of existing data from the perspective of environmental protection and to identify areas of data paucity. Data have been organised in a format compatible with a reference organism approach, for selected radionuclides, and efforts have been taken to identify the factors that may be of importance in the context of dosimetric and dose-effects analyses. These reference organism categories had been previously selected by identifying organism groups that were likely to experience the highest levels of radiation exposure, owing to high uptake levels or residence in a particular habitat, for defined scenarios. Significant data gaps in the CF database have been identified, notably for marine mammals and birds. Most empirical information pertains to a limit suite of radionuclides, particularly 137 Cs, 210 Po and 99 Tc. A methodology has been developed to help bridge this information deficit. This has been based on simple dynamic, biokinetic models that mainly use parameters derived from laboratory-based study and field observation. In some cases, allometric relationships have been employed to allow further model parameterization. Initial testing of the model by comparing model output with empirical data sets suggest that the models provide sensible equilibrium CFs. Furthermore, analyses of modelling results suggest that for some radionuclides, in particularly those with long effective half-lives, the time to equilibrium can be far greater than the life-time of an organism. This clearly emphasises the limitations of applying a universal equilibrium approach. The methodology, therefore, has an added advantage that non-equilibrium scenarios can be considered in a more rigorous manner. Further refinements to the modelling approach might be attained by exploring the importance of various model parameters, through sensitivity analyses, and by identifying those

    An emerging dimension of 21(st) century integrative biology is knowledge translation in global health. The maternal mortality rate in Somalia is amongst the highest in the world. We set out to study the "know-do" gap in family planning measures in Somalia, with a view to inform future interventions for knowledge integration between theory and practice. We interviewed 360 Somali females of reproductive age and compared university-educated females to women with less or no education, using structured interviews, with a validated questionnaire. The mean age of marriage was 18 years, with 4.5 pregnancies per marriage. The mean for the desired family size was 9.3 and 10.5 children for the university-educated group and the less-educated group, respectively. Importantly, nearly 90% of the university-educated group knew about family planning, compared to 45.6% of the less-educated group. All of the less-educated group indicated that they would never use contraceptives, as compared to 43.5% of the university-educated group. Prevalence of contraceptive use among ever-married women was 4.3%. In the less-educated group, 80.6% indicated that they would not recommend contraceptives to other women as compared to 66.0% of the university-educated group. There is a huge gap between knowledge and practice regarding family planning in Somalia. The attendant reasons for this gap, such as level of education, expressed personal religious beliefs and others, are examined here. For primary health care to gain traction in Africa, we need to address the existing "know-do" gaps that are endemic and adversely impacting on global health. This is the first independent research study examining the knowledge gaps for family planning in Somalia in the last 20 years, with a view to understanding knowledge integration in a global world. The results shall guide policy makers, donors, and implementers to develop a sound family planning policy and program to improve maternal and child health in 21(st

    The objective of this study was to explore public health informatics (PHI) training programs that currently exist to meet the growing demand for a trained global workforce. We used several search engines, scientific databases, and the websites of informatics organizations; sources included PubMed, Google, the American Medical Informatics Organization, and the International Medical Informatics Organization. The search was conducted from May to July 2011 and from January to February 2012 using key words such as informatics, public health informatics, or biomedical informatics along with academic programs, training, certificate, graduate programs, or postgraduate programs. Course titles and catalog descriptions were gathered from the program or institution websites. Variables included PHI program categories, location and mode of delivery, program credits, and costs. Each course was then categorized based on its title and description as available on the Internet. Finally, we matched course titles and descriptions with the competencies for PHIs determined by Centers for Disease Control and Prevention (CDC). Descriptive analysis was performed to report means and frequency distributions for continuous and categorical variables. Stratified analysis was performed to explore average credits and cost per credit among both the public and private institutions. Fifteen PHI programs were identified across 13 different institutions, the majority of which were US-based. The average number of credits and the associated costs required to obtain PHI training were much higher in private as compared to public institutions. The study results suggest that a need for online contextual and cost-effective PHI training programs exists to address the growing needs of professionals worldwide who are using technology to improve public health in their respective countries.

    It is estimated that about 30 % of the world's undiscovered gas and 13 % of undiscovered oil resources are located in the Arctic. Sea ice loss with climate change is progressing rapidly and by 2050 the Arctic could be nearly sea ice free in summer. This will allow for Arctic industrialization, commercial shipping, fishing and tourism to increase. Given that the world population is projected to grow beyond 9 billion by mid-century needing more resources, partly to be found in the Arctic, it can be expected that the current urbanization trend in the region will accelerate in the future. Against this background, it is likely that new local emission sources emerge which may lead to increased burdens of air pollutants such as particulate matter (PM), reactive nitrogen, and ozone. Typical Arctic emission sources include road transport, domestic fuel burning, diesel emissions, as well as industrial sources such as oil and gas extraction, metallurgical smelting, power generation as well as shipping in coastal areas. These emissions and their impacts remain poorly quantified in the Arctic. Boreal wildfires can already affect summertime air quality and may increase in frequency and size in a warmer climate. Locally produced air pollution, in combination with cold, stagnant weather conditions and inversion layers in winter, can also lead to significant localized pollutant concentrations, often in exceedance of air quality standards. Despite these concerns, very few process studies on local air pollution in or near inhabited areas in the Arctic have been conducted, which significantly limits our understanding of atmospheric chemical reactions involving air pollutants under Arctic conditions (e.g., extremely cold and dry air with little solar radiation in winter) and their impacts on human health and ecosystems. We will provide an overview of our current understanding of local air pollution and its impacts in Arctic urban environments and highlight key gaps. We will discuss a

    Full Text Available We propose a Conceptual Model-based Systems Biology framework for qualitative modeling, executing, and eliciting knowledge gaps in molecular biology systems. The framework is an adaptation of Object-Process Methodology (OPM, a graphical and textual executable modeling language. OPM enables concurrent representation of the system's structure-the objects that comprise the system, and behavior-how processes transform objects over time. Applying a top-down approach of recursively zooming into processes, we model a case in point-the mRNA transcription cycle. Starting with this high level cell function, we model increasingly detailed processes along with participating objects. Our modeling approach is capable of modeling molecular processes such as complex formation, localization and trafficking, molecular binding, enzymatic stimulation, and environmental intervention. At the lowest level, similar to the Gene Ontology, all biological processes boil down to three basic molecular functions: catalysis, binding/dissociation, and transporting. During modeling and execution of the mRNA transcription model, we discovered knowledge gaps, which we present and classify into various types. We also show how model execution enhances a coherent model construction. Identification and pinpointing knowledge gaps is an important feature of the framework, as it suggests where research should focus and whether conjectures about uncertain mechanisms fit into the already verified model.

    The potential for academic research institutions to facilitate knowledge exchange and influence evidence-informed decision-making has been gaining ground. Schools of public health (SPHs) may play a key knowledge brokering role-serving as agencies of and for development. Understanding academic-policymaker networks can facilitate the enhancement of links between policymakers and academic faculty at SPHs, as well as assist in identifying academic knowledge brokers (KBs). Using a census approach, we administered a sociometric survey to academic faculty across six SPHs in Kenya to construct academic-policymaker networks. We identified academic KBs using social network analysis (SNA) in a two-step approach: First, we ranked individuals based on (1) number of policymakers in their network; (2) number of academic peers who report seeking them out for advice on knowledge translation and (3) their network position as 'inter-group connectors'. Second, we triangulated the three scores and re-ranked individuals. Academic faculty scoring within the top decile across all three measures were classified as KBs. Results indicate that each SPH commands a variety of unique as well as overlapping relationships with national ministries in Kenya. Of 124 full-time faculty, we identified 7 KBs in 4 of the 6 SPHs. Those scoring high on the first measure were not necessarily the same individuals scoring high on the second. KBs were also situated in a wide range along the 'connector/betweenness' measure. We propose that a composite score rather than traditional 'betweenness centrality', provides an alternative means of identifying KBs within these networks. In conclusion, SNA is a valuable tool for identifying academic-policymaker networks in Kenya. More efforts to conduct similar network studies would permit SPH leadership to identify existing linkages between faculty and policymakers, shared linkages with other SPHs and gaps so as to contribute to evidence-informed health policies. © The

  5. Expanding the use of empiricism in nursing: can we bridge the gap between knowledge and clinical practice?

    Giuliano, Karen K

    2003-04-01

    The philosophy of Aristotle and its impact on the process of empirical scientific inquiry has been substantial. The influence of the clarity and orderliness of his thinking, when applied to the acquisition of knowledge in nursing, can not be overstated. Traditional empirical approaches have and will continue to have an important influence on the development of nursing knowledge through nursing research. However, as nursing is primarily a practice discipline, the transition from empirical and syllogistic reasoning is problematic. Other types of inquiry are essential in the application of nursing knowledge obtained by empirical scientific approaches and to understand how that knowledge can best be used in the care of patients. This paper reviews the strengths and limitations of syllogistic reasoning by applying it to a recently published study on temperature measurement in nursing. It then discusses possible ways that the empirical knowledge gained from that study and confirmed in its reasoning by logical analysis could be used in the daily care of critically ill patients. It concludes by highlighting the utility of broader approaches to knowledge development, including interpretative approaches and contemporary empiricism, as a way to bridge the gap between factual empirical knowledge and the practical application of that knowledge in everyday clinical nursing practice.

    This paper is a report of a correlational study of the relations of nursing students' acquired reflective skills, practical skills and theoretical knowledge on their perception of coherence between theory and practice. Reflection is considered a key factor in bridging the gap between theory and practice. However, it is not evident whether reflective skills are primarily generic in nature or whether they develop from a theoretical knowledge base or the acquisition of practical skills. This study is a secondary analysis of existing data. The data are part of a student survey that was conducted among third-year nursing students in Norway during the spring of 2007. A total of 446 nursing students participated in this study and the response rate was 71%. Structural equation modelling analyses were performed. The results indicate that students' perception of coherence between theory and practice during initial nursing education is directly influenced by reflective skills and theoretical knowledge. The results also reveal that reflective skills have mediating effects and that practical skills have a fully mediated and theoretical knowledge a partially mediated influence on students' perception of coherence. The findings imply that helping students perceive coherence between theory and practice in nursing education, developing students' reflective skills and strengthening the theoretical components of the initial nursing education programme might be beneficial. The results suggest that reflective thinking is not merely a generic skill but rather a skill that depends on the acquisition of relevant professional knowledge and experience. © 2011 Blackwell Publishing Ltd.

    This work presents a critical assessment of the state and quality of knowledge around the aquatic photochemistry of human- and veterinary-use pharmaceuticals from laboratory experiments and field observations. A standardized scoring rubric was used to assess relevant studies within four categories: experimental design, laboratory-based direct and indirect photolysis, and field/solar photolysis. Specific metrics for each category are defined to evaluate various aspects of experimental design (e.g., higher scores are given for more appropriate characterization of light source wavelength distribution). This weight of evidence-style approach allowed for identification of knowledge strengths and gaps covering three areas: first, the general extent of photochemical data for specific pharmaceuticals and classes; second, the overall quality of existing data (i.e., strong versus weak); and finally, trends in the photochemistry research around these specific compounds, e.g. the observation of specific and consistent oversights in experimental design. In general, those drugs that were most studied also had relatively good quality data. The four pharmaceuticals studied experimentally at least ten times in the literature had average total scores (lab and field combined) of ≥29, considered decent quality; carbamazepine (13 studies; average score of 31), diclofenac (12 studies; average score of 31), sulfamethoxazole (11 studies; average score of 34), and propranolol (11 studies; average score of 29). Major oversights and errors in data reporting and/or experimental design included: lack of measurement and reporting of incident light source intensity, lack of appropriate controls, use of organic co-solvents in irradiation solutions, and failure to consider solution pH. Consequently, a number of these experimental parameters were likely a cause of inconsistent measurements of direct photolysis rate constants and quantum yields, two photochemical properties that were highly

    The cosmetic industry is among the first adaptors of nanotechnology through the use of engineered nanoparticles (ENPs) to enhance the performance of their products and meet the customers' needs. Recently, there have been increasing concerns from different societal stakeholders (e.g., governments, environmental activist pressure groups, scientists, general public, etc.) concerning the safety and environmental impact of ENPs used in cosmetics. This review paper seeks to address the twin concerns of the safety of cosmetics and the potential environmental impacts due to the constituent chemicals-the ENPs. The safety aspect is addressed by examining recently published scientific data on the possibility of ENPs penetrating human skin. Data indicates that although particular types of ENPs can penetrate into the skin, until now no penetration has been detected beyond the stratum corneum of the ENPs used in cosmetics. Yet, important lessons can be learned from the more recent studies that identify the characteristics of ENPs penetrating into and permeating through human skin. On the part of the environmental impact, the scientific literature has very limited or none existent specific articles addressing the environmental impacts of ENPs owing to the cosmetic products. Therefore, general ecotoxicological data on risk assessment of ENPs has been applied to ascertain if there are potential environmental impacts from cosmetics. Results include some of the first studies on the qualitative and quantitative risk assessment of ENPs from cosmetics and suggest that further research is required as the knowledge is incomplete to make definitive conclusions as is the case with skin penetration. The authors conclude that the cosmetic industry should be more transparent in its use of nanotechnology in cosmetic products to facilitate realistic risk assessments as well as scientists and pressure groups being accurate in their conclusions on the general applicability of their findings

    The importance of consistent, accurate and unambiguous messages are well documented in oral health promotion literature. Whether the reality of delivering messages in the field fulfils these principle is questionable. This paper explores the perceptions of dental professionals, healthcare professionals and lay community members with regard to key oral health messages in order to highlight any inconsistencies and knowledge gaps between and within groups for disease risk factors. A questionnaire was administered to individuals who belonged to three groups: dental professionals, healthcare professionals and lay community members. The questionnaire established knowledge regarding risk factors for caries, periodontal disease and erosion. Thirty-five (57.4%) of the dental group answered the whole questionnaire correctly, with 22 (27.8%) and 9 (5.1%) of the healthcare and lay community group answering the whole questionnaire correctly, respectively. The question of fluoride levels in children's toothpaste was the main reason for incorrect answers in the dental group. The results of this survey demonstrate a knowledge gradient from dental professionals through to healthcare professionals and then to lay members of the community. The knowledge base observed in the dental group is reflected in the other two groups as would be expected albeit with a significant gap between each group. As expected the dental professionals are generally well informed, but not as well informed as could be expected.

    Psoriasis is a chronic inflammatory disease that affects around 100 million people worldwide. The burden of disease is high, but more recent therapies show promising results. Clinicians need, however, more training in the use of such therapies. Project ECHO ® (Extension for Community Healthcare Outcomes) is structured around the promise of delivering medical education at a distance, empowering clinicians who operate in remote areas. The use of instant messaging services, such as WhatsApp ® Messenger, has the potential to improve on the existing framework and bridge the existing gap of knowledge. This article reports on a study concerning the implementation of a WhatsApp discussion group in Project ECHO Psoriasis in Argentina. One hundred thirty-two dermatologists in Argentina were invited to participate in the WhatsApp discussion group. After 1 year of participation, a follow-up questionnaire was used to assess the effectiveness of the project. Eighty dermatologists participated. All questions placed in the discussion were answered by a psoriasis specialist, 79% of which were answered within the first 5 min. Clinicians report significant improvement in diagnosis, comorbidities, and treatment with both conventional and biological therapies. Preliminary results are promising. This new cost-effective solution builds on the existing Project ECHO Psoriasis in Argentina and shows potential in bridging the gap of knowledge, promoting better clinical decisions through empowerment of medical doctors operating in remote locations. Further research is needed to increase generalization of the results. Moreover, it would be interesting to match the data from the discussion group with follow-up questionnaires.

    The armored scale Aulacaspis yasumatsui invaded the northern range of the cycad Cycas micronesica in 2003, and epidemic tree mortality ensued due to a lack of natural enemies of the insect. We quantified cycad demographic responses to the invasion, but the ecological responses to the selective removal of this foundation species have not been addressed. We use this case to highlight information gaps in our understanding of how alien invasive phytophagous insects force cascading adverse ecosystem changes. The mechanistic role of unique canopy gaps, oceanic island examples and threatened foundation species with distinctive traits are three issues that deserve research efforts in a quest to understand this facet of ecosystem change occurring across multiple settings globally.

  14. Bridging the Nagoya Compliance Gap: The Fundamental Role of Customary Law in Protection of Indigenous Peoples’ Resource and Knowledge Rights

    Full Text Available The Nagoya Protocol requires states to ensure that access to and use of genetic resources and traditional knowledge of Indigenous peoples and local communities is subject to their prior informed consent (PIC. It also requires states to take into consideration their customary laws. However, it lacks effective compliance mechanisms, a gap exposed in draft European legislation that sidesteps the Nagoya Protocol’s obligations regarding PIC and customary law, leaving traditional knowledge largely unprotected. This article examines the status of customary law under international, regional and national law, and the challenges and opportunities for securing recognition of its role in the protection of traditional knowledge. The article contends that all commercial and development activities with the potential to impact on Nagoya Protocol rights will in the future need to ensure compliance with relevant customary law. It finds state reluctance to adopt measures to ensure consideration of customary law shortsighted and likely to lead to increased litigation. It concludes that customary law has a key role to play in closing the Nagoya compliance gap but to do so it will need to be supported by enforcement mechanisms such as disclosure of origin regimes in intellectual property law.

  15. Towards prevention of vitamin D deficiency and beyond: knowledge gaps and research needs in vitamin D nutrition and public health.

    The North American Institute of Medicine (IOM) recently published their report on dietary reference intakes (DRI) for Ca and vitamin D. The DRI committee's deliberations underpinning this most comprehensive report on vitamin D nutrition to date benefited hugely from a much expanded knowledge base in vitamin D over the last decade or more. However, since their release, the vitamin D DRI have been the subject of intense controversy, which is largely due to the persistence of fundamental knowledge gaps in vitamin D. These can be identified at the levels of exposure, metabolism, storage, status, dose-response, function and beneficial or adverse health effects, as well as safe and effective application of intake recommendations at the population level through sustainable food-based approaches. The present review provides a brief overview of the approach used by the IOM committee to revise the DRI for vitamin D and to collate from a number of authoritative sources key knowledge gaps in vitamin D nutrition from the public health perspective. A number of research topics are outlined and data requirements within these are identified and mapped to the risk assessment framework used by the DRI committee. While not intended as an exhaustive list, it provides a basis for organising and prioritising research efforts in the area of vitamin D, which may offer a perspective on the major areas in need of attention. It is intended to be of use to researchers, national policy makers, the public health community, industry groups and other relevant stakeholders including funding institutions.

    The prevalence of atrial fibrillation (AF) is substantial and increasing. Stroke is common in AF and can have devastating consequences. Oral anticoagulants are effective in reducing stroke risk, but are underutilized. We sought to characterize the impact of stroke on AF patients and their caregivers, gaps in knowledge and perspective between physicians and patients, and barriers to effective communication and optimal anticoagulation use. A survey was administered to AF patients with and without history of stroke, caregivers of stroke survivors, and physicians across the range of specialties caring for AF and stroke patients. While AF patients (n = 499) had limited knowledge about stroke, they expressed great desire to learn more and take action to reduce their risk. They were often dissatisfied with the education they had received and desired high-quality written materials. Stroke survivors (n = 251) had poor functional outcomes and often underestimated the burden of caring for them. Caregivers (n = 203) also wished they had received more information about reducing stroke risk before their survivor's event. They commonly felt overwhelmed and socially isolated. Physicians (n = 504) did not prescribe anticoagulants as frequently as recommended by guidelines. Concerns about monitoring anticoagulation and patient compliance were commonly reported barriers. Physicians may underestimate patient willingness to take anticoagulants. We identified significant knowledge gaps among patients, caregivers, and physicians in relation to AF and stroke. Furthermore, gaps in perspective often lead to suboptimal communication and decision making. Increased education and better communication between all stakeholders are needed to reduce the impact of stroke in AF. Copyright © 2015 Heart Rhythm Society and National Stroke Association.

  18. Phenomena identification ranking table and knowledge base gaps and needs for the modular high-temperature gas-cooled reactor

    International Nuclear Information System (INIS)

    Tokuhiro, Akira; Potirniche, Gabriel; Rink, Karl

    2009-01-01

    The U.S. is developing a modular high-temperature gas-cooled reactor (MHTGR) under the Next Generation Nuclear Plant (NGNP); also known as the Very High Temperature Reactor (VHTR). The generic MHTGR is a graphite-moderated, gas-cooled reactor (GCR) of either a prismatic modular (block-type, PMR) or pebble-bed (PBR) core configuration. The pebble-bed design requires new attention with respect to neutronics, materials, thermal hydraulic, safety and licensing relative to the set of phenomena and engineering analyses associated with the current fleet of legacy LWRs. In fact, the relative knowledge and experiential base on gas reactors is small in comparison to the LWR. There is a dated body of knowledge from some 25+ years ago on GCRs; recently there is a renewed interest. Thus in the present design and development phase of the NGNP/VHTR, there are relevant thermohydraulic safety issues surrounding the MHTGR with issues impacting foremost the design review process. A common phenomena with respect to PMR and PBR core design, is that concerning 'graphite dust' and its interaction and transport with potential fission products (FP) that may be present within the graphite and subsequently in the primary system. The nature of the graphite and FPs, when circulated or transported in the primary, and possibly beyond, is of concern as potentially an relevant 'source term' (radionuclide inventory) of the MHTGR. Based on NUREG/CR-6944, Volumes 1-5, the author briefly describes the state-of-the art knowledge base on graphite dust and FP transport with respect to the anticipated design of the MHTGR. In addition, from the Phenomena Identification and Ranking Tables (PIRTs) developed in these reports we concurrently identify and describe 'gaps and needs' of the knowledge base. That is, we also present the knowledge base gaps and needs with respect to the following: 1) R and D needs relative to PIRTs, 2) (experimental) database needs relative to PIRTs, and 3) simulation and modeling

    The focus of this chapter was to summarize the advances made over last 40+ years, as reported in various chapters of this book, in understanding, modeling, and mapping terrestrial vegetation using hyperspectral remote sensing (or imaging spectroscopy) using sensors that are ground-based, truck-mounted, airborne, and spaceborne. As we have seen in various chapters of this book and synthesized in this chapter, the advances made include: (a) significantly improved characterization and modeling of a wide array of biophysical and biochemical properties of vegetation, (b) ability to discriminate plant species and vegetation types with high degree of accuracies (c) reducing uncertainties in determining net primary productivity or carbon assessments from terrestrial vegetation, (d) improved crop productivity and water productivity models, (b), (e) ability to access stress resulting from causes such as management practices, pests and disease, water deficit or excess; , and (f) establishing more sensitive wavebands and indices to detect plant water\\moisture content. The advent of spaceborne hyperspectral sensors (e.g., NASA’s Hyperion, ESA’s PROBA, and upcoming NASA’s HyspIRI) and numerous methods and techniques espoused in this book to overcome Hughes phenomenon or data redundancy when handling large volumes of hyperspectral data have generated tremendous interest in advancing our hyperspectral applications knowledge base over larger spatial extent such as region, nation, continent, and globe.

    Computer assistance is increasingly common in surgery. However, the amount of information is bound to overload processing abilities of surgeons. We propose methods to recognize the current phase of a surgery for context-aware information filtering. The purpose is to select the most suitable subset of information for surgical situations which require special assistance. We combine formal knowledge, represented by an ontology, and experience-based knowledge, represented by training samples, to recognize phases. For this purpose, we have developed two different methods. Firstly, we use formal knowledge about possible phase transitions to create a composition of random forests. Secondly, we propose a method based on cultural optimization to infer formal rules from experience to recognize phases. The proposed methods are compared with a purely formal knowledge-based approach using rules and a purely experience-based one using regular random forests. The comparative evaluation on laparoscopic pancreas resections and adrenalectomies employs a consistent set of quality criteria on clean and noisy input. The rule-based approaches proved best with noisefree data. The random forest-based ones were more robust in the presence of noise. Formal and experience-based knowledge can be successfully combined for robust phase recognition.

    The quality of dementia care in hospitals is typically substandard. Staff members are underprepared for providing care to older people with dementia. The objective of the present study was to examine dementia care knowledge, attitude and behavior regarding self-education about dementia care among nurses working in different wards. This was a descriptive cross-sectional study. The present study was carried out from July 2013 to December 2013. In total, 387 nurses working in different wards were recruited from two hospitals in Taiwan by using convenience sampling. The nurses completed a self-report questionnaire on demographic data, experience and learning behavior, and attitude towards dementia care, and a 16-item questionnaire on dementia care knowledge. Descriptive and inferential statistics were used to analyze the status and differences in dementia care knowledge among nurse in different wards. The average dementia care knowledge score was 10.46 (SD 2.13), with a 66.5% mean accuracy among all nurses. Dementia care knowledge was significantly associated with age, nursing experience, possession of a registered nurse license, holding a bachelor's degree, work unit, training courses and learning behavior towards dementia care. The dementia care knowledge of the emergency room nurses was significantly lower than that of the psychiatric and neurology ward nurses. A significantly lower percentage of emergency room nurses underwent dementia care training and actively searched for information on dementia care, compared with the psychiatric and neurology ward nurses. Hospital nurses show a knowledge gap regarding dementia care, especially emergency room nurses. Providing dementia care training to hospital nurses, particularly emergency room nurses, is crucial for improving the quality of care for patients with dementia.

    Chapman, Kathy; Kelly, Bridget; King, Lesley

    2009-06-01

    Research in the field of food marketing to children requires a better understanding of the research gaps in order to inform policy development. The purpose of this paper was to propose a framework for classifying food marketing research, using Australian research on food marketing to children to demonstrate how this framework can be used to determine knowledge gaps. A literature review of research databases and 'grey' material was conducted to identify research from the previous 10 years. Studies were classified according to their research focus, and media type, as either: exposure, including content analyses; effects of exposure, including opinions, attitudes and actions resulting from food marketing exposure; regulations, including the type and level of regulation that applies to food marketing; or breaches of regulations, including instances where marketing regulations have been violated. The majority of Australian research on food marketing to children has focused on television advertising and exposure research. Research has consistently shown that the content of food marketing directed at children is predominately for unhealthy foods. There is a lack of research on the effects of food marketing, which would be valuable to inform policy. The development of a logical framework for food marketing research allows for the identification of research gaps and enables research priorities to be identified.

    Hand washing is considered as one of the most effective hygiene promotion activities for public health in developing countries. This study compared hand washing knowledge and practices in BRAC's water; sanitation and hygiene (WASH) programme areas over time. This study is a cross-sectional comparative study between baseline (2006), midline (2009) and end-line (2011) surveys in 50 sub-districts from the first phase of the programme. Thirty thousand households from 50 sub-districts were selected in two steps: i) 30 villages were selected from each sub-district by cluster sampling, and ii) 20 households were chosen systematically from each village. The matched households were considered (26,404 in each survey) for analysis. Data were collected from households through face-to-face interview using a pre-tested questionnaire. Respondents were the adult female members of the same households, who had knowledge of day-to-day household activities related to water, sanitation and hygiene. A gap between perception and practice of proper hand washing practices with soap was identified in the study areas. Hand washing practice with soap before eating was much lower than after defecation. In baseline data, 8% reported to wash their hands with soap which significantly increased to 22% in end line. Hand washing knowledge and practices before cooking food, before serving food and while handling babies is considerably limited than other critical times. A multivariate analysis shows that socio-economic factors including education of household head and respondent, water availability and access to media have strong positive association with hand washing with soap. Gap between knowledge and practice still persists in hand washing practices. Long term and extensive initiatives can aware people about the effectiveness of hand washing.

    The energy levels created in supersaturated n-type silicon substrates with titanium implantation in the attempt to create an intermediate band in their band-gap are studied in detail. Two titanium ion implantation doses (10{sup 13 }cm{sup -2} and 10{sup 14 }cm{sup -2}) are studied in this work by conductance transient technique and admittance spectroscopy. Conductance transients have been measured at temperatures of around 100 K. The particular shape of these transients is due to the formation of energy barriers in the conduction band, as a consequence of the band-gap narrowing induced by the high titanium concentration. Moreover, stationary admittance spectroscopy results suggest the existence of different energy level configuration, depending on the local titanium concentration. A continuum energy level band is formed when titanium concentration is over the Mott limit. On the other hand, when titanium concentration is lower than the Mott limit, but much higher than the donor impurity density, a quasi-continuum energy level distribution appears. Finally, a single deep center appears for low titanium concentration. At the n-type substrate, the experimental results obtained by means of thermal admittance spectroscopy at high reverse bias reveal the presence of single levels located at around E{sub c}-425 and E{sub c}-275 meV for implantation doses of 10{sup 13 }cm{sup −2} and 10{sup 14 }cm{sup −2}, respectively. At low reverse bias voltage, quasi-continuously distributed energy levels between the minimum of the conduction bands, E{sub c} and E{sub c}-450 meV, are obtained for both doses. Conductance transients detected at low temperatures reveal that the high impurity concentration induces a band gap narrowing which leads to the formation of a barrier in the conduction band. Besides, the relationship between the activation energy and the capture cross section values of all the energy levels fits very well to the Meyer-Neldel rule. As it is known

    Full Text Available ABSTRACT Objectives: assess mothers’ parenting knowledge and skills associated with the parental competence health promotion and monitoring for newborns and infants aged up to six months and determine the key characteristics of mothers who are better prepared for parenting. Method: cross-sectional study conducted in three health centers belonging to a Local Health Unit in the Northern Region of Portugal. Data was collected using clinical interviews conducted with pregnant women or mothers with a child aged up to six months. The tool used contained 21 child health promotion and monitoring indicators associated with different assessment moments: pregnancy, 1st/2nd week, 1st/2nd month, 3rd/4th month, and 5th/6th month. Results: we assessed the knowledge and skills of 629 women. Learning needs were identified for each of the indicators. The mothers who were better prepared for parenting tended to have a higher level of schooling, resided with the child’s father, had other children, had planned pregnancy, and intended to breastfeed. Conclusions: the results showed that knowledge and skills were lacking for each of the periods assessed by this study. First-time single mothers whose pregnancy was unplanned and who did not prepare themselves for parenthood may be considered a vulnerable group.

    We describe our stakeholder engagement process for grant application development that occurred as part of our integrated knowledge translation plan and make recommendations for researchers. In phase 1, a stakeholder consultation group was developed. In phase 2, surveys regarding knowledge gathering, research agenda, and research collaboration preferences were sent to 333 cross-sectoral youth-serving organizations in Ontario, including family and consumer organizations. In phase 1, 28 stakeholders from six sectors participated in the consultation group and provided input on multiple aspects of the proposal. Through this process, 19 stakeholders adopted formal roles within the project. In phase 2, 206 surveys were received (response rate = 62%). Survey responses supported the grant focus (concurrent youth mental health and substance use problems). Respondents also prioritized project goals and provided specific feedback on research and knowledge translation. Finally, although some stakeholders chose greater involvement, most survey respondents indicated a preference for a moderate level of participation in research rather than full team membership. Despite short timelines and feasibility challenges, stakeholders can be meaningfully engaged in and contribute to the grant proposal development process. Consideration is needed for the practical challenges that stakeholder organizations face in supporting and participating in research.

    2015-06-01

    This paper addresses the movements 'evidence-based' (EBM) and 'personalized' (PM) medicine. The former is being criticized for failing to do justice to clinical complexity and human individuality. The latter aims at tailoring medical knowledge for every patient in a personalized fashion. Instrumental to this effort is the technological development engendering unlimited amounts of data about bodily fragments. The aim of this article is to stimulate a debate about the notion of the body and knowledge in medicine. An authentic sickness history is used as a vantage point for a more comprehensive account of biomedicine. The analysis of the sickness history demonstrates how biomedical logic guided all approaches in the care for this particular patient. Each problem was identified and treated separately, whereby neglecting the interaction between body parts and systems, and between the woman's bodily condition and her experiences. The specialists involved seemed to look for phenomena that fit categories of disorders 'belonging' to their field. These approaches engendered unintended effects: chronification, poly-pharmacy and multi-morbidity, leading to an unsustainable increase in medical costs. The article elucidates how the status that professionals ascribe to the body has vital implications for what they regard as relevant and how they interpret the information they have collected. On this ground, we challenge both the prevailing and tacitly accepted separation between the physical body and human experience and the view of knowledge underpinning EBM and PM. The growing molecularization of the body veils decisive sources of human illness. © 2014 John Wiley & Sons, Ltd.

    The time span between knowledge becoming available and its integration into daily clinical routine is lengthy. This phenomenon is explored in this study. We used the outcomes of our activities for investigating and strengthening the research-based activities to improve physical health in the routines of clinical psychiatric wards as examples for our analyses. The time span between new knowledge becoming available and its implementation into general clinical treatment is very long. However, a shortening of this time span is seen through active leadership backup and clinical research experience among psychiatrists and staff in the wards. In particular, the involvement of medical students interested in clinical research activities seems to have a positive impact. Academia needs to be re-implemented into clinical psychiatry. Staff with research experience is needed in all professions to increase evidence-based practice. Leaders must take responsibility for implementing new knowledge into the routines of the department and must support staff in these activities on a daily basis. © 2015 John Wiley & Sons A/S.

    2015-04-01

    Full Text Available Menstrual hygiene is an issue that is insufficiently acknowledged. Menstruation and menstrual practices are still clouded by taboos and socio - cultural restrictions resulting in adolescent girls lacking knowledge and remaining ignorant of the scientific facts and hygienic health practices, which sometimes res ult into adverse health outcomes. Menstrual hygiene, a very important risk factor for reproductive tract infections (RTI, is a vital aspect of health education. Menarche is a significant milestone in the transitory developmental journey of an adolescent. Poor personal hygiene and defective menstrual management practices give rise to repeated reproductive tract infections (RTIs, which are otherwise preventable. Menstruation is generally considered as unclean in the Indian society. Isolation of the menstrua ting girls and restrictions being imposed on them in the family, have reinforced a negative attitude towards this phenomenon. There is a substantial lacuna in the knowledge about menstruation among adolescent. This study was conducted to assess the knowled ge, attitudes and practices of adolescent school girls of a secondary school in an urban setting. It was found that there was lack of knowledge in specific areas. This study throws light on lack of basic amenities in school for girls which in turn leads to unhygienic practices during menstruation. These reinforce the fact that health education has to be more effective and also that the need of the hour is basic amenities in schools.

    Southern Africa produces almost a third of the Earth's biomass burning (BB) aerosol particles. Particles lofted into the mid-troposphere are transported westward over the South-East (SE) Atlantic, home to one of the three permanent subtropical stratocumulus (Sc) cloud decks in the world. The SE Atlantic stratocumulus deck interacts with the dense layers of BB aerosols that initially overlay the cloud deck, but later subside and may mix into the clouds. These interactions include adjustments to aerosol-induced solar heating and microphysical effects, and their global representation in climate models remains one of the largest uncertainties in estimates of future climate. Hence, new observations over the SE Atlantic have significant implications for global climate change scenarios. Our understanding of aerosol-cloud interactions in the SE Atlantic is hindered both by the lack of knowledge on aerosol and cloud properties, as well as the lack of knowledge about detailed physical processes involved. Most notably, we are missing knowledge on the absorptive and cloud nucleating properties of aerosols, including their vertical distribution relative to clouds, on the locations and degree of aerosol mixing into clouds, on the processes that govern cloud property adjustments, and on the importance of aerosol effects on clouds relative to co-varying synoptic scale meteorology. We discuss the current knowledge of aerosol and cloud property distributions based on satellite observations and sparse suborbital sampling. Recent efforts to make full use of A-Train aerosol sensor synergies will be highlighted. We describe planned field campaigns in the region to address the existing knowledge gaps. Specifically, we describe the scientific objectives and implementation of the five synergistic, international research activities aimed at providing some of the key aerosol and cloud properties and a process-level understanding of aerosol-cloud interactions over the SE Atlantic: NASA

  15. Extensive gaps and biases in our knowledge of a well-known fauna: Implications for integrating biological traits into macroecology

    KAUST Repository

    2011-12-09

    Aim Ecologists seeking to describe patterns at ever larger scales require compilations of data on the global abundance and distribution of species. Comparable compilations of biological data are needed to elucidate the mechanisms behind these patterns, but have received far less attention. We assess the availability of biological data across an entire assemblage: the well-documented demersal marine fauna of the United Kingdom. We also test whether data availability for a species depends on its taxonomic group, maximum body size, the number of times it has been recorded in a global biogeographic database, or its commercial and conservation importance. Location Seas of the United Kingdom. Methods We defined a demersal marine fauna of 973 species from 15 phyla and 40 classes using five extensive surveys around the British Isles. We then quantified the availability of data on eight key biological traits (termed biological knowledge) for each species from online databases. Relationships between biological knowledge and our predictors were tested with generalized linear models. Results Full data on eight fundamental biological traits exist for only 9% (n= 88) of the UK demersal marine fauna, and 20% of species completely lack data. Clear trends in our knowledge exist: fish (median biological knowledge score = six traits) are much better known than invertebrates (one trait). Biological knowledge increases with biogeographic knowledge and (to a lesser extent) with body size, and is greater in species that are commercially exploited or of conservation concern. Main conclusions Our analysis reveals deep ignorance of the basic biology of a well-studied fauna, highlighting the need for far greater efforts to compile biological trait data. Clear biases in our knowledge, relating to how well sampled or \\'important\\' species are suggests that caution is required in extrapolating small subsets of biologically well-known species to ecosystem-level studies. © 2011 Blackwell

    2012-07-01

    There is growing optimism in the global health community that the HIV epidemic can be halted. After decades of relying primarily on behavior change to prevent HIV transmission, a second generation of prevention efforts based on medical or biological interventions such as male circumcision and preexposure prophylaxis--the use of antiretroviral drugs to protect uninfected, at-risk individuals--has shown promising results. This article calls for a third generation of HIV prevention efforts that would integrate behavioral, biological, and structural interventions focused on the social, political, and environmental underpinnings of the epidemic, making use of local epidemiological evidence to target affected populations. In this third wave, global programs should deliver HIV prevention services together with cost-effective interventions for reproductive health and for tuberculosis, malaria, and other diseases. Additionally, new efforts are needed to address gaps in HIV prevention research, evaluation, and implementation. Increased and sustained funding, along with evidence-based allocation of funds, will be necessary to accelerate the decline in new HIV infections.

    2007-01-01

    The American Heart Association, along with the International Liaison Committee on Resuscitation, recently made changes to the paediatric resuscitation guidelines. Knowledge translation (KT) is imperative, but there is a lack of sufficient evidence for appropriate methodologies for implementation of these guidelines. Paediatric resuscitation presents many challenges; cases happen infrequently, affording few opportunities for implementation of the new guidelines, and are highly stressful and filled with uncertainty. Some KT strategies have shown some success in causing a notable degree of change in behaviour, but none have shown a striking difference when used alone. Previous efforts to disseminate current guidelines centred on development of courses for health care providers and preparing paediatric residents and paediatricians for circumstances they could encounter with paediatric acute illness. None of the studies assessing these techniques measured direct patient outcomes, and only a few demonstrated some long-term knowledge acquisition among trainees. The purpose of the present review was to illuminate the challenges, offer future directions for KT and outline potentially more effective methodologies and strategies to overcome current barriers.

    NASA's Indigenous Capacity Building Initiative is aimed to provide remote sensing training, mentoring, and research opportunities to the indigenous community. A key programmatic goal is the co-production of place-based trainings where participants have the opportunity to address specific natural resource research and management issues facing their tribal lands. Three primary strategies have been adopted to engage with our tribal partners, these include: (1) the use of existing tribal networks and conferences such as the National Tribal GIS Conference, (2) coordination with other federal agencies such as the Bureau of Indian Affairs (BIA) and tribal liaisons at regional Climate Science Centers, and (3) connecting with tribes directly. Regional partner visits with tribes, such as meetings with the Samish Indian Nation, are integral to cultivate trusting, collaborative, and sustained partnerships and an understanding of how Earth Observations can be applied to the unique set of challenges and goals each tribe faces. As the program continues to grow, we aim to increase our incorporation of Traditional Ecological Knowledge (TEK) into technical methods and to develop trainings tailored to thematic areas of interest to specific tribes. Engagement and feedback are encouraged to refine our approaches to increase capacity within the indigenous community to utilize NASA Earth Observations.

  2. Deconstructing brain-derived neurotrophic factor actions in adult brain circuits to bridge an existing informational gap in neuro-cell biology

    2016-01-01

    Full Text Available Brain-derived neurotrophic factor (BDNF plays an important role in neurodevelopment, synaptic plasticity, learning and memory, and in preventing neurodegeneration. Despite decades of investigations into downstream signaling cascades and changes in cellular processes, the mechanisms of how BDNF reshapes circuits in vivo remain unclear. This informational gap partly arises from the fact that the bulk of studies into the molecular actions of BDNF have been performed in dissociated neuronal cultures, while the majority of studies on synaptic plasticity, learning and memory were performed in acute brain slices or in vivo. A recent study by Bowling-Bhattacharya et al., measured the proteomic changes in acute adult hippocampal slices following treatment and reported changes in proteins of neuronal and non-neuronal origin that may in concert modulate synaptic release and secretion in the slice. In this paper, we place these findings into the context of existing literature and discuss how they impact our understanding of how BDNF can reshape the brain.

    To evaluate the neonatal resuscitation competence of obstetrical trainees to assess the gap in knowledge and to determine training needs. The cross-sectional study was conducted at the Department of Gynaecology and Obstetrics, Civil Hospital, Karachi, from January to March 2013 and comprised House Officers and Postgraduate trainees. A questionnaire was used to test the evaluation skills of different conditions and choice of appropriate action required during neonatal resuscitation. Data was collected and analysed through SPSS 17.0. Of the 102 obstetrical trainees, 44 (43.1%) were House Officers and 58 (56.9%) were Postgraduate trainees with an overall mean age 25.69 +/- 2.3 years. Only 19 (18.6%) subjects cleared the test; 8 (42.1%) of them were House Officers and 11 (57.9%) were Postgraduate trainees. The result did not show any significant difference between those who had previous training or those who had performed neonatal resuscitation and those who had no such exposure. Majority, 92 (90.2%) considered their knowledge inadequate and 99 (97%) favoured that updated neonatal resuscitation programmes should be periodically arranged. The study showed inadequate level of knowledge on neonatal resuscitation amongst obstetrical trainees. There is urgent need of formal training programmes which can make doctors skilful enough to face any adverse neonatal outcome professionally.

    The marine areas of South America (SA) include almost 30,000 km of coastline and encompass three different oceanic domains--the Caribbean, the Pacific, and the Atlantic--ranging in latitude from 12∘N to 55∘S. The 10 countries that border these coasts have different research capabilities and taxonomic traditions that affect taxonomic knowledge. This paper analyzes the status of knowledge of marine biodiversity in five subregions along the Atlantic and Pacific coasts of South America (SA): the Tropical East Pacific, the Humboldt Current,the Patagonian Shelf, the Brazilian Shelves, and the Tropical West Atlantic, and it provides a review of ecosystem threats and regional marine conservation strategies. South American marine biodiversity is least well known in the tropical subregions (with the exception of Costa Rica and Panama). Differences in total biodiversity were observed between the Atlantic and Pacific oceans at the same latitude. In the north of the continent, the Tropical East Pacific is richer in species than the Tropical West Atlantic, however, when standardized by coastal length, there is very little difference among them. In the south, the Humboldt Current system is much richer than the Patagonian Shelf. An analysis of endemism shows that 75% of the species are reported within only one of the SA regions, while about 22% of the species of SA are not reported elsewhere in the world. National and regional initiatives focusing on new exploration, especially to unknown areas and ecosystems, as well as collaboration among countries are fundamental to achieving the goal of completing inventories of species diversity and distribution.These inventories will allow accurate interpretation of the biogeography of its two oceanic coasts and latitudinal trends,and will also provide relevant information for science based policies.

  5. Knowledge and Behavioural Factors Associated with Gender Gap in Acquiring HIV Among Youth in Uganda.

    The increasing prevalence of HIV in Uganda during the last decade (7.5% in 2004-05 to 8.3% in 2011 among women and 5.0% in 2004-05 to 6.1% among men in 2011 of 15 to 49 years) clearly shows that women are disproportionately affected by HIV epidemic. Hence, we assessed the prevalence of HIV and focused on differences in risky sexual behaviour and knowledge of HIV among Ugandan youth. Uganda AIDS Indicator Survey 2011 data was used. The total samples of men and women (15 to 24 years), interviewed and tested for HIV, were 3450 and 4504 respectively. The analysis of risky sexual behaviour was based on 1941 men and 3127 women who had ever had sex and were tested for HIV. Pearson's Chi-square test and multivariate logistic regression analysis were used. Findings showed that young women were almost two times more vulnerable than young men in acquiring HIV (OR=1.762, Pgap in risky sexual behaviour and new transmission of HIV in Uganda. Significance for public healthThe present study represents the evidence of a recent increase in HIV infection in Uganda from the latest round of AIDs indicator survey. This manuscript describes how young women (15-24 years-old) are disproportionately HIV-infected compared to young men in Uganda. They are more vulnerable to HIV than young men. Moreover, it is also observed that young women are at greater risk of acquiring HIV because of their risky sexual behaviour and inappropriate knowledge of HIV transmission. Some educational programmes, growing gender equity in HIV/AIDS activities and services, dropping violence and coercion, addressing male norms and behaviours, improving women's legal protection, and rising women's access to income and productive resources can be very effective in minimising the vulnerability of young women to HIV/AIDS.

    Knowledge of the extent and intensity of fishing activities is critical to inform management in relation to fishing impacts on marine conservation features. Such information can also provide insight into the potential socio-economic impacts of closures (or other restrictions) of fishing grounds that could occur through the future designation of Marine Conservation Zones (MCZs). We assessed the accuracy and validity of fishing effort data (spatial extent and relative effort) obtained from Fishers' Local Knowledge (LK) data compared to that derived from Vessel Monitoring System (VMS) data for a high-value shellfish fishery, the king scallop (Pecten maximus L.) dredge fishery in the English Channel. The spatial distribution of fishing effort from LK significantly correlated with VMS data and the correlation increased with increasing grid cell resolution. Using a larger grid cell size for data aggregation increases the estimation of the total area of seabed impacted by the fishery. In the absence of historical VMS data for vessels ≤15 m LOA (Length Overall), LK data for the inshore fleet provided important insights into the relative effort of the inshore (<6 NM from land) king scallop fishing fleet in the English Channel. The LK data provided a good representation of the spatial extent of inshore fishing activity, whereas representation of the offshore fishery was more precautionary in terms of defining total impact. Significantly, the data highlighted frequently fished areas of particular importance to the inshore fleet. In the absence of independent sources of geospatial information, the use of LK can inform the development of marine planning in relation to both sustainable fishing and conservation objectives, and has application in both developed and developing countries where VMS technology is not utilised in fisheries management.

    Part I of this contribution on innovative nuclear fuels gives a summary of current developments and problems of today's fuels, i.e. enriched UO 2 and UO 2 with a few % of PUO 2 (MOX fuel) or Gd 2 O 3 (as burnable neutron poison). The problems and property changes caused by high burnups (e.g. degradation of the thermal conductivity, polygonization or formation of the rim-structure) are discussed. Subsequently, the concepts for new fuels to burn excess Pu and to achieve an effective transmutation of the minor actinides Np, Am and Cm are treated. The criteria for the choice of suitable fuels and different fuel types (high Pu-content fuels, nitrides, U-free fuels, inert matrix supported fuels, cercers, cermets, etc.) are discussed. Part II of this contribution on innovative nuclear fuels deals with the properties of relevance of the different materials suggested to be used in innovative fuels which range from pure actinide fuel such as PuN and AmO 2 to spinel MgAl 2 O 4 and zircon ZrSiO 4 for inert matrix-based fuels, etc. The available knowledge on materials research aspects is summarized with emphasis on the physics of radiation damage. It is shown that significant gaps in the present knowledge exist, e.g. for the minor actinide compounds, and suggestions are made to fill these gaps in order to achieve a sufficient data base to design and operate suitable innovative fuels in a near future.

    The purpose of this review is to summarize the available evidence-based HIV prevention interventions tailored for transgender people. A limited number of evidence-based HIV prevention interventions have been tested with transgender populations. Most existing interventions target behavior change among transgender women, with only one HIV prevention program evaluated for transgender men. Studies addressing biomedical interventions for transgender women are ongoing. Few interventions address social and structural barriers to HIV prevention, such as stigma, discrimination, and poverty. Evidence-based multi-level interventions that address the structural, biomedical, and behavioral risks for HIV among transgender populations, including transgender men, are needed to address disparities in HIV prevalence. Future research should address not only pre-exposure prophylaxis uptake and condom use but also structural barriers that limit access to these prevention strategies.

    Full Text Available The aim of this pilot study was to evaluate if the residents of psychiatry and clinical psychology from the city of Buenos Aires knew any of the existing mental health Clinical Practice and Treatment Guidelines (CPTGs. We asked residents their opinion about CPTGs and, also, if they followed their recommendations in clinical practice. We asked 59 mental health residents (28 physicians and 29 psychologists with different years of clinical training to fill a questionnaire to know their opinion about CPTGs and also if they follow the CPTG recommendations in their clinical practice. We found that 79.31% of residents did not know any CPTG. Eighty percent of the residents who did know any CPTG have a positive opinion about CPTGs. Finally, the American Psychiatric Association Guidelines were the most known CPTGs. The authors emphasize the need for a clinical guidelines diffusion policy in Buenos Aires city and particularly as a clinical and training resource for mental health residents.

    Physical inactivity is a common risk factor for several non-communicable diseases (NCDs). Increasing physical activity could reduce the burden of disease due to major NCDs and increase life expectancy. Undergraduate physiotherapy students represent a group of young-adults expected to have a good knowledge of physical activity. We evaluated physical activity levels of undergraduate physiotherapy students of University of Colombo, Sri Lanka and determined their motives and barriers for participation in physical activity. All physiotherapy undergraduates studying at the University of Colombo, Sri Lanka in 2013 were invited for the study. Phase one was a quantitative study to evaluate the physical activity levels and phase two was a qualitative study to identify motives and barriers for physical activity and sports in the same cohort. Physical activity levels (phase 1) were assessed using the interviewer administered International Physical Activity Questionnaire (long-version). The qualitative study (phase 2) was conducted in the same population using Focus Group Discussions ( n  = 3) and individual In-depth Interviews ( n  = 5). Sample size in phase 1 and phase 2 were 113 (response rate = 98%; [N-115]) and 87 (response rat = 97%; [N-90]) respectively. Mean age (±SD) of participants was 23.4 ± 1 years. The mean weekly total MET minutes (±SD) of the study population was 1791.25 ± 3097. According to the IPAQ categorical score a higher percentage of participants were 'inactive' (48.7%), while only 15.9% were in the 'Highly active' group. Lack of support and encouragement received during childhood to engage in sports activity seem to have played an important role in continuing their exercise behavior through to the adult life. Academic activities were given priority by both parents and teachers. The environment and support from teachers, family and friends were important to initiate and adhere to sports and physical activity. A higher

    In-hospital mortality of acute myocardial infarction with ST segment elevation remains high and is influenced by many factors, some of which are modifiable such as time to treatment initiation and modality of treatment. It is well established that reperfusion therapy is the gold-standard in the management of ST-elevation acute myocardial infarction. Despite recent developments and clear, comprehensible guidelines recommendations, it remains difficult to disseminate this knowledge to medical practitioners. The German Chest Pain Unit shows that the best door-to-balloon time is reached when patients contact the Emergency Medical Systems (EMS) directly, rather than when referred by the general practitioner (GP), or are transferred from another hospital, or present as a self-referral. In order to improve mortality in ST-elevation acute myocardial infarction, patients must be able to recognize symptoms and call the EMS as soon as possible, in addition to having an ECG within ten minutes and direct access to reperfusion therapy (PPCI preferred). The German Registry has highlighted the importance of training both patients and doctors. Copyright © 2017 Elsevier B.V. All rights reserved.

    The U.S. Environmental Protection Agency (EPA) has committed to issuing in 2012 new or revised criteria designed to protect the health of those who use surface waters for recreation. For this purpose, the U.S. EPA has been conducting epidemiologic studies to establish relationships between microbial measures of water quality and adverse health outcomes among swimmers. New methods for testing water quality that would provide same-day results will likely be elements of the new criteria. Although the epidemiologic studies upon which the criteria will be based were conducted at Great Lakes and marine beaches, the new water quality criteria may be extended to inland waters (IWs). Similarities and important differences between coastal waters (CWs) and IWs that should be considered when developing criteria for IWs were the focus of an expert workshop. Here, we summarize the state of knowledge and research needed to base IWs microbial criteria on sound science. Two key differences between CWs and IWs are the sources of indicator bacteria, which may modify the relationship between indicator microbes and health risk, and the relationship between indicators and pathogens, which also may vary within IWs. Monitoring using rapid molecular methods will require the standardization and simplification of analytical methods, as well as greater clarity about their interpretation. Research needs for the short term and longer term are described.

    The black guillemot Cepphus grylle has been identified as a species likely to interact with marine renewable energy devices, specifically tidal turbines, with the potential to experience negative impacts. This likelihood is primarily based on the species being a diving seabird, and an inshore, benthic forager often associating with tidal streams. These behavioural properties may bring them into contact with turbine blades, or make them susceptible to alterations to tidal current speed, and/or changes in benthic habitat structure. We examine the knowledge currently available to assess the potential impacts of tidal stream turbines on black guillemot ecology, highlight knowledge gaps and make recommendations for future research. The key ecological aspects investigated include: foraging movements, diving behaviour, seasonal distribution, other sources of disturbance and colony recovery. Relating to foraging behaviour, between studies there is heterogeneity in black guillemot habitat use in relation to season, tide, diurnal cycles, and bathymetry. Currently, there is also little knowledge regarding the benthic habitats associated with foraging. With respect to diving behaviour, there is currently no available research regarding how black guillemots orientate and manoeuvre within the water column. Black guillemots are considered to be a non-migratory species, however little is known about their winter foraging range and habitat. The effect of human disturbance on breeding habitat and the metapopulation responses to potential mortalities are unknown. It is clear further understanding of black guillemot foraging habitat and behaviour is needed to provide renewable energy developers with the knowledge to sustainably locate tidal turbines and mitigate their impacts.

    2013-01-01

    Differential access to everyday technology and healthcare amongst safety net patients is associated with low technological and health literacies, respectively. These low rates of literacy produce a complex patient "knowledge gap" that influences the effectiveness of telehealth technologies. To understand this "knowledge gap", six focus groups (2 African-American and 4 Latino) were conducted with patients who received teleretinal screenings in U.S. urban safety-net settings. Findings indicate that patients' "knowledge gap" is primarily produced at three points: (1) when patients' preexisting personal barriers to care became exacerbated in the clinical setting; (2) through encounters with technology during screening; and (3) in doctor-patient follow-up. This "knowledge gap" can produce confusion and fear, potentially affecting patients' confidence in quality of care and limiting their disease management ability. In rethinking the digital divide to include the consequences of this knowledge gap faced by patients in the clinical setting, we suggest that patient education focus on both their disease and specific telehealth technologies deployed in care delivery.

    Patient-centered outcomes research (PCOR) aims to give patients a better understanding of the treatment options to enable optimal decision-making. As nonoperative alternatives are now being evaluated in children for acute appendicitis, we surveyed patients and their families regarding their knowledge of appendicitis and evaluated whether providing basic medical information would affect their perception of the disease and allow them to more rationally consider the treatment alternatives. Families of children aged 5-18 presenting to the Emergency Department with suspected appendicitis were recruited for a tablet-based interactive educational survey. One hundred subjects (caregivers and patients ≥ 15 years) were questioned before and after an education session about their understanding of appendicitis, including questions on three hypothetical treatment options: urgent appendectomy, antibiotics alone, or initial antibiotics followed by elective appendectomy. Subjects were clearly informed that urgent appendectomy is currently the standard of care. Only 14% of respondents correctly identified the mortality rate of appendicitis (17 deaths/year according to the 2010 US census) when compared with other extremely rare causes of death. Fifty-four and 31% thought it was more common than death from lightning (40/year) and hunting-associated deaths (44/year), respectively. Eighty-two percent of respondents believed it "likely" or "very likely" that the appendix would rupture if operation was at all delayed, and 81% believed that rupture of the appendix would rapidly lead to severe complications and death. In univariate analysis, this perception was significantly more prevalent for mothers (odds ratio, (OR) 5.19, confidence interval (CI) 1.33-21.15), and subjects who knew at least one friend or relative who had a negative experience with appendicitis (OR 5.53, CI 1.40-25.47). Following education, these perceptions changed significantly (53% still believed that immediate

    Background. Health care providers play a crucial role for realization of joint zoonotic diseases surveillance by human and animal health sectors, yet there is limited evidence. Hence, this study aimed to determine knowledge and practice gap of health care providers towards the approach for Rabies and Anthrax in Southwest Ethiopia. Methods. A cross-sectional survey was conducted from December 16, 2014, to January 14, 2015. Eligible health care providers were considered for the study. Data were entered in to Epi-data version 3.1 and analyzed using SPSS version 20. Results. A total of 323 (92.02%) health care providers participated in the study. Three hundred sixteen (97.8%) of participants reported that both human and animal health sectors can work together for zoonotic diseases while 96.9% of them replied that both sectors can jointly conduct surveillance. One hundred seventeen (36.2%) of them reported that their respective sectors had conducted joint surveillance for zoonotic diseases. Their involvement was, however, limited to joint outbreak response. Conclusion. There is good opportunity in health care providers' knowledge even though the practice was unacceptably low and did not address all surveillance components. Therefore, formal joint surveillance structure should be in place for optimal implementation of surveillance.

  1. EcAMSat and BioSentinel: Autonomous Bio Nanosatellites Addressing Strategic Knowledge Gaps for Manned Spaceflight Beyond LEO

    Padgen, Mike

    2017-01-01

    Manned missions beyond low Earth orbit (LEO) require that several strategic knowledge gaps about the effects of space travel on the human body be addressed. NASA Ames Research Center has been the leader in developing autonomous bio nanosatellites, including past successful missions for GeneSat, PharmaSat, and OOREOS, that tackled some of these issues. These nanosatellites provide in situ measurements, which deliver insight into the dynamic changes in cell behavior in microgravity. In this talk, two upcoming bio nanosatellites developed at Ames, the E. coli Antimicrobial Satellite (EcAMSat) and BioSentinel, will be discussed. Both satellites contain microfluidic systems that precisely deliver nutrients to the microorganisms stored within wells of fluidic cards. Each well, in turn, has its own 3-color LED and detector system which is used to monitor changes in metabolic activity with alamarBlue, a redox indicator, and the optical density of the cells. EcAMSat investigates the effects of microgravity on bacterial resistance to antimicrobial drugs, vital knowledge for understanding how to maintain the health of astronauts in long-term and beyond LEO spaceflight. The behavior of wild type and mutant uropathic E. coli will be compared in microgravity and with ground data to help understand the molecular mechanisms behind antibiotic resistance and how these phenotypes might change in space. BioSentinel seeks to directly measure the effects of space radiation on budding yeast S. cerevisiae, particularly double strand breaks (DSB). While hitching a ride on the SLS EM-1 mission (Orions first unmanned mission to the moon) in 2018, BioSentinel will be kicked off and enter into a heliocentric orbit, becoming the first study of the effects of radiation on living organisms outside LEO since the Apollo program. The yeast are stored in eighteen independent 16-well microfluidic cards, which will be individually activated over the 12 month mission duration. In addition to the wild

    Despite considerable attention currently being given to facilitating the use of research results in public health practice, several concerns remain, resulting in the so-called know-do gap. This article aims to identify the key tensions causing the know-do gap from a broad perspective by using a systemic approach and considering the public health sector as an innovation system. An exploratory qualitative design including in-depth semi-structured interviews was used, with 33 interviewees from different actor categories in the Dutch public health innovation system. The analyses employed an innovation system matrix to highlight the principal tensions causing the know-do gap. Seven key tensions were identified, including: research priorities determined by powerful players; no consensus about criteria for knowledge quality; different perceptions about the knowledge broker role; competition engendering fragmentation; thematic funding engendering fragmentation; predominance of passive knowledge sharing; and lack of capacity among users to use and influence research. The identified tensions indicate that bridging the know-do gap requires much more than linking research to practice or translating knowledge. An innovation system perspective is crucial in providing information on the total picture of knowledge exchange within the Dutch public health sector. Such a system includes broader stakeholder involvement as well as the creation of social, economic, and contextual conditions (achieving shared visions, building networks, institutional change, removing financial and infrastructural barriers), as these create conducive factors at several system levels and induce knowledge co-creation and innovation.

    Despite recent advances spearheaded by molecular approaches and novel technologies, species description and DNA sequence information are significantly lagging for fungi compared to many other groups of organisms. Large scale sequencing of vouchered herbarium material can aid in closing this gap. Here, we describe an effort to obtain broad ITS sequence coverage of the approximately 6000 macrofungal-species-rich herbarium of the Museum of Natural History in Venice, Italy. Our goals were to investigate issues related to large sequencing projects, develop heuristic methods for assessing the overall performance of such a project, and evaluate the prospects of such efforts to reduce the current gap in fungal biodiversity knowledge. The effort generated 1107 sequences submitted to GenBank, including 416 previously unrepresented taxa and 398 sequences exhibiting a best BLAST match to an unidentified environmental sequence. Specimen age and taxon affected sequencing success, and subsequent work on failed specimens showed that an ITS1 mini-barcode greatly increased sequencing success without greatly reducing the discriminating power of the barcode. Similarity comparisons and nonmetric multidimensional scaling ordinations based on pairwise distance matrices proved to be useful heuristic tools for validating the overall accuracy of specimen identifications, flagging potential misidentifications, and identifying taxa in need of additional species-level revision. Comparison of within- and among-species nucleotide variation showed a strong increase in species discriminating power at 1-2% dissimilarity, and identified potential barcoding issues (same sequence for different species and vice-versa). All sequences are linked to a vouchered specimen, and results from this study have already prompted revisions of species-sequence assignments in several taxa.

    Sexual and gender minorities (SGM) include individuals with a wide range of sexual orientations, physical characteristics, and gender identities and expressions. Data suggest that people in this group face a significant and poorly understood set of additional health risks and bear a higher burden of some diseases compared to the general population. A large amount of data is available on HIV/AIDS, but far less on other health problems. In this review we aimed to synthesize the knowledge on the burden of communicable and non-communicable diseases, mental health conditions and violence experienced by SGM, based on available systematic reviews. We conducted a global review of systematic reviews, including searching the Cochrane and the Campbell Collaboration libraries, as well as PubMed, using a range of search terms describing the populations of interest, without time or language restrictions. Google Scholar was also scanned for unpublished literature, and references of all selected reviews were checked to identify further relevant articles. We found 30 systematic reviews, all originally written in English. Nine reviews provided data on HIV, 12 on other sexually transmitted infections (STIs), 4 on cancer, 4 on violence and 3 on mental health and substance use. A quantitative meta-analysis was not possible. The findings are presented in a narrative format. Our review primarily showed that there is a high burden of disease for certain subpopulations of SGM in HIV, STIs, STI-related cancers and mental health conditions, and that they also face high rates of violence. Secondly, our review revealed many knowledge gaps. Those gaps partly stem from a lack of original research, but there is an equally urgent need to conduct systematic and literature reviews to assess what we already know on the disease burden in SGM. Additional reviews are needed on the non-biological factors that could contribute to the higher disease burden. In addition, to provide universal access to

    Full Text Available Background & Objectives: The use of dental implants in partially or completely edentulous patients has proved effective and an accepted treatment modality with predictable long-term success. Dental implants are becoming a popular choice for replacing the missing teeth because of increased awareness about implants both in dentists and patients. The objective of the study was to assess the basic knowledge and education about dental implants among general dental practitioners (GDPs of Nepal.Materials & Methods:  A cross sectional questionnaire was carried out among 110 GDPs which consist of twenty questions that were divided into three categories; first with some basic knowledge in implant dentistry, second with clinical knowledge of dental implants and third with dental implant education and training.Results: Out of 110 GDPs, 72.7% had basic knowledge about implant dentistry and 65.5% were not aware about advance surgical procedures like sinus lift and guided bone regeneration. All the GDPs were positive regarding more training and education in dental implants and 95.5% of them would like to incorporate dental implant treatment in their practice in future. Conclusion: GDPs should have adequate knowledge and training of dental implants which can be incorporated at undergraduate or post doctoral level so that they are skilled to provide quality dental implant therapy to their patients confidently.

    To investigate whether training in writing for scholarly publication, journal editing, or manuscript peer review effectively improves educational outcomes related to the quality of health research reporting. We searched MEDLINE, Embase, ERIC, PsycINFO, and the Cochrane Library for comparative studies of formalized, a priori-developed training programs in writing for scholarly publication, journal editing, or manuscript peer review. Comparators included the following: (1) before and after administration of a training program, (2) between two or more training programs, or (3) between a training program and any other (or no) intervention(s). Outcomes included any measure of effectiveness of training. Eighteen reports of 17 studies were included. Twelve studies focused on writing for publication, five on peer review, and none fit our criteria for journal editing. Included studies were generally small and inconclusive regarding the effects of training of authors, peer reviewers, and editors on educational outcomes related to improving the quality of health research. Studies were also of questionable validity and susceptible to misinterpretation because of their risk of bias. This review highlights the gaps in our knowledge of how to enhance and ensure the scientific quality of research output for authors, peer reviewers, and journal editors. Copyright © 2015 The Authors.

    The vast majority of infants are born in poor countries, but most of our knowledge about infants and children has emerged from high-income countries. In 2003, M. Tomlinson and L. Swartz conducted a survey of articles on infancy between 1996 and 2001 from major international journals, reporting that a meager 5% of articles emanated from parts of the world other than North America, Europe, or Australasia. In this article, we conducted a similar review of articles on infancy published between 2002 and 2012 to assess whether the status of cross-national research has changed in the subsequent decade. Results indicate that despite slight improvements in research output from the rest of world, only 2.3% of articles published in 11 years included data from low- and middle-income countries--where 90% of the world's infants live. These discrepancies are indicative of the progress still needed to bridge the so-called 10/90 gap (S. Saxena, G. Paraje, P. Sharan, G. Karam, & R. Sadana,) in infant mental health research. Cross-national collaboration is urgently required to ensure expansion of research production in low-resource settings. © 2014 Michigan Association for Infant Mental Health.

  10. Addressing the Knowledge Gaps in Agroecology and Identifying Guiding Principles for Transforming Conventional Agri-Food Systems

    2017-02-01

    Full Text Available Today’s society faces many challenges when it comes to food production: producing food sustainably, producing enough of it, distributing food, consuming enough calories, consuming too many calories, consuming culturally-appropriate foods, and reducing the amount of food wasted. The distribution of power within the current mainstream agri-food system is dominated by multinational agri-businesses that control the flow of goods and wealth through the system. This hegemony has implemented a regime whose structures reinforce its control. A growing response to the current agri-food regime is the rise of agroecology, in both developed and developing country contexts. This is not a new phenomenon, but it has evolved over time from its Latin American origins. However, agroecology is not a monolithic block and represents many different perceptions of what it means to advance agroecology and ways in which it can help today’s society tackle the crisis of the agri-food system. This paper addresses these sometimes discordant view points, as well as the gaps in our knowledge regarding agroecology in an effort to lay out some guiding principles for how we can move forward in transforming the current agri-food system to achieve sustainability and a more equitable distribution of power and resources.

    The Trauma Hemostasis and Oxygenation Research Network held its third annual Remote Damage Control Resuscitation Symposium in June 2013 in Bergen, Norway. The Trauma Hemostasis and Oxygenation Research Network is a multidisciplinary group of investigators with a common interest in improving outcomes and safety in patients with severe traumatic injury. The network's mission is to reduce the risk of morbidity and mortality from traumatic hemorrhagic shock, in the prehospital phase of resuscitation through research, education, and training. The concept of remote damage control resuscitation is in its infancy, and there is a significant amount of work that needs to be done to improve outcomes for patients with life-threatening bleeding secondary to injury. The prehospital phase of resuscitation is critical in these patients. If shock and coagulopathy can be rapidly identified and minimized before hospital admission, this will very likely reduce morbidity and mortality. This position statement begins to standardize the terms used, provides an acceptable range of therapeutic options, and identifies the major knowledge gaps in the field.

    Sims, Leslie D

    2013-09-01

    A range of measures has been recommended and used for the control and prevention of avian influenza. These measures are based on the assessment of local epidemiological situations, field observations and other scientific information. Other non-technical factors are (or in some cases should be) taken into account when developing and recommending control measures. The precise effects under field conditions of most individual interventions applied to control and prevent avian influenza have not been established or subjected to critical review, often because a number of measures are applied simultaneously without controls. In most cases, the combination of measures used results in control or elimination of the virus although there are some countries where this has not been the case. In others, especially those with low poultry density, it is not clear whether the link between the adoption of a set of measures and the subsequent control of the disease is causative. This article discusses the various measures recommended, with particular emphasis on stamping out and vaccination, examines how these measures assist in preventing zoonotic infections with avian influenza viruses and explores gaps in knowledge regarding their effectiveness. © 2013 Blackwell Publishing Ltd.

    Full text: Options for effective management of MAM have improved in the past decade as new products have been rolled out and coverage has increased through community-based treatment. As a result, the Lancet series on nutrition of 2013 included attention to the management of MAM, whereas it had not in 2008. The Lancet authors concluded that MAM interventions should be included in modelling exercises aimed at estimating the potential impact of packages of interventions to prevent child mortality. However, they also noted that while some evidence of effectiveness exists, sound empirical data on outcomes achieved in emergency and non-emergency settings alike need to be much better documented and appropriately costed. Since the Lancet series of 2013 was published, at least three separate reviews of the evidence have emerged, involving slightly differing approaches (systematic review, meta-analysis and/or Delphic assessment). This paper for IAEA CN-217 offers an overview of the findings of the Lancet 2013 paper and the content of the three subsequent evidence reviews. It presents a critique of differences in their approaches and findings, and highlights areas where significant gaps in knowledge remain. Lessons for future systematic reviews will be underlined, and priority areas for new research that has operational relevance will be specified. (author)

    Full Text Available Namibia has a rich history in veterinary health but little is known about the vector-borne diseases that affect companion dogs and cats. The aim of this review is to summarise the existing published and available unpublished literature, put it into a wider geographical context, and explore some significant knowledge gaps. To date, only two filarial pathogens (Dirofilaria repens and Acanthocheilonema dracunculoides and three tick-borne pathogens (Babesia canis vogeli, Hepatozoon canis and Ehrlichia canis have been reported. Most studies have focused solely on dogs and cats in the urban Windhoek and surrounding areas, with almost nothing reported in rural farming areas, in either the populous northern regions or the low-income urban areas where animal owners have limited access to veterinary services. With the development of several biomedical training programmes in the country, there is now an excellent opportunity to address zoonotic vector-borne diseases through a One Health approach so as to assess the risks to small companion animals as well as diseases of public health importance.

    The Murray-Darling Basin incorporates Australia's three longest rivers and is important for an agricultural industry worth more than $9 billion per annum, a rich biodiversity of habitat and species, and the very life of its traditional owners. The complex and sometimes enigmatic relationships between modes of variability and Australian regional rainfall distribution means that reliable projections of future water availability remain highly uncertain. Persistent drought, with associated heat stress and high fire danger, and episodic flooding rains present further challenges. Indeed, recent extremes likely herald a tipping point for the communities and ecosystems that rely on the river system. The Barmah-Millewa region in the Murray-Darling Basin is the heart of Yorta Yorta Traditional Tribal Lands. The Yorta Yorta continue to assert their inherent rights to country and have shown through oral, documentary and material evidence, that their social, spiritual, economic and cultural links with country have never been broken. Current water policy and practice, highly contested community consultation processes, cross-border governance issues and a changing social landscape create in this region a microcosm for understanding the complex demands of economic, environmental and cultural security along the Murray-Darling Basin as the climate changes. New approaches to bridging the gap between scientific and Indigenous epistemologies have emerged in recent years, including for example ecosystem-based adaptation (Vignola et al. 2009) and the analysis of cultural water flows (Weir 2010). The potential for innovation using these approaches has informed a study that investigates how the deep knowledge of country of the Yorta Yorta people can be combined with state of the art climate science to develop a better understanding of the competing demands on water resources in the Barmah-Millewa region now and in the future. An important dimension of this collaborative work with the Yorta

    Strategic priority setting and implementation of strategies to reduce maternal mortality are key to the post Millennium Development Goal (MDG) 2015 agenda. This article highlights the feasibility and the advantages of using a systematized tacit knowledge approach, using data from maternal health program personnel, to identify local challenges to implementing policies and programs to inform the post MDG era. Communities of practice, conceived as groups of people sharing professional interests, experiences and knowledge, were formed with diverse health personnel implementing maternal health programs in Mexico and Nicaragua. Participants attended several workshops and developed different online activities aiming to strengthen their capacities to acquire, analyze, adapt and apply research results and to systematize their experience and knowledge of the actual implementation of these programs. Concept mapping, a general method designed to organize and depict the ideas of a group on a particular topic, was used to manage, discuss and systematize their tacit knowledge about implementation problems of the programs they work in. Using a special online concept mapping platform, participants prioritized implementation problems by sorting them in conceptual clusters and rating their importance and feasibility of solution. Two hundred and thirty-one participants from three communities of practice in each country registered on the online concept mapping platform and 200 people satisfactorily completed the sorting and rating activities. Participants further discussed these results to prioritize the implementation problems of maternal health programs. Our main finding was a great similarity between the Mexican and the Nicaraguan general results highlighting the importance and the feasibility of solution of implementation problems related to the quality of healthcare. The use of rigorously organized tacit knowledge of health personnel proved to be a feasible and useful tool for

    We conducted a mixed-methods knowledge synthesis to assess the effectiveness of interventions to improve caregivers' involvement in decision making with seniors, and to describe caregivers' experiences of decision making in the absence of interventions. We analyzed forty-nine qualitative, fourteen quantitative, and three mixed-methods studies. The qualitative studies indicated that caregivers had unmet needs for information, discussions of values and needs, and decision support, which led to negative sentiments after decision making. Our results indicate that there have been insufficient quantitative evaluations of interventions to involve caregivers in decision making with seniors and that the evaluations that do exist found few clinically significant effects. Elements of usual care that received positive evaluations were the availability of a decision coach and a supportive decision-making environment. Additional rigorously evaluated interventions are needed to help caregivers be more involved in decision making with seniors. Project HOPE—The People-to-People Health Foundation, Inc.

    Full Text Available Nature-based solutions promoting green and blue urban areas have significant potential to decrease the vulnerability and enhance the resilience of cities in light of climatic change. They can thereby help to mitigate climate change-induced impacts and serve as proactive adaptation options for municipalities. We explore the various contexts in which nature-based solutions are relevant for climate mitigation and adaptation in urban areas, identify indicators for assessing the effectiveness of nature-based solutions and related knowledge gaps. In addition, we explore existing barriers and potential opportunities for increasing the scale and effectiveness of nature-based solution implementation. The results were derived from an inter- and transdisciplinary workshop with experts from research, municipalities, policy, and society. As an outcome of the workshop discussions and building on existing evidence, we highlight three main needs for future science and policy agendas when dealing with nature-based solutions: (i produce stronger evidence on nature-based solutions for climate change adaptation and mitigation and raise awareness by increasing implementation; (ii adapt for governance challenges in implementing nature-based solutions by using reflexive approaches, which implies bringing together new networks of society, nature-based solution ambassadors, and practitioners; (iii consider socio-environmental justice and social cohesion when implementing nature-based solutions by using integrated governance approaches that take into account an integrative and transdisciplinary participation of diverse actors. Taking these needs into account, nature-based solutions can serve as climate mitigation and adaptation tools that produce additional cobenefits for societal well-being, thereby serving as strong investment options for sustainable urban planning.

    Local and regional scientific journals are important factors in bridging gaps in health knowledge translation in low-and middle-income countries. We assessed indexing, citations and publishing standards of journals from the Eastern Mediterranean region. For journals from 22 countries in the collection of the Index Medicus for the Eastern Mediterranean Region (IMEMR), we analyzed indexing in bibliographical databases and citations during 2006-2009 to published items in 2006 in Web of Science (WoS) and SCOPUS. Adherence to editorial and publishing standards was assessed using a special checklist. Out of 419 journals in IMEMR, 19 were indexed in MEDLINE, 23 in WoS and 46 in SCOPUS. Their impact factors ranged from 0.016 to 1.417. For a subset of 175 journals with available tables of contents from 2006, articles published in 2006 from 93 journals received 2068 citations in SCOPUS (23.5% self-citations) and articles in 86 journals received 1579 citations in WoS (24.3% self-citations) during 2006-2009. Citations to articles came mostly from outside of the Eastern Mediterranean region (76.8% in WoS and 75.4% in SCOPUS). Articles receiving highest number of citations presented topics specific for the region. Many journals did not follow editorial and publishing standards, such addressing requirements about the patient's privacy rights (68.0% out of 244 analyzed), policy on managing conflicts of interest (66.4%), and ethical conduct in clinical and animal research (66.4%). Journals from the Eastern Mediterranean are visible in and have impact on global scientific community. Coordinated effort of all stakeholders in journal publishing, including researchers, journal editors and owners, policy makers and citation databases, is needed to further promote local journals as windows to the research in the developing world and the doors for valuable regional research to the global scientific community.

    Full Text Available It has been suggested that the widespread use of neonicotinoid insecticides threatens bees, but research on this topic has been surrounded by controversy. In order to synthesize which research approaches have been used to examine the effect of neonicotinoids on bees and to identify knowledge gaps, we systematically reviewed research on this subject that was available on the Web of Science and PubMed in June 2015. Most of the 216 primary research studies were conducted in Europe or North America (82%, involved the neonicotinoid imidacloprid (78%, and concerned the western honey bee Apis mellifera (75%. Thus, little seems to be known about neonicotinoids and bees in areas outside Europe and North America. Furthermore, because there is considerable variation in ecological traits among bee taxa, studies on honey bees are not likely to fully predict impacts of neonicotinoids on other species. Studies on crops were dominated by seed-treated maize, oilseed rape (canola and sunflower, whereas less is known about potential side effects on bees from the use of other application methods on insect pollinated fruit and vegetable crops, or on lawns and ornamental plants. Laboratory approaches were most common, and we suggest that their capability to infer real-world consequences are improved when combined with information from field studies about realistic exposures to neonicotinoids. Studies using field approaches often examined only bee exposure to neonicotinoids and more field studies are needed that measure impacts of exposure. Most studies measured effects on individual bees. We suggest that effects on the individual bee should be linked to both mechanisms at the sub-individual level and also to the consequences for the colony and wider bee populations. As bees are increasingly facing multiple interacting pressures future research needs to clarify the role of neonicotinoids in relative to other drivers of bee declines.

    2016-02-01

    As an emerging industry, Marine Renewable Energy (MRE) is expected to play a major contributory role if the UK is to successfully reach it's desired target of renewable energy production by 2020. However, due to the competing objectives and priorities of MRE and other industries, for example fisheries, and in the delivering of conservation measures, the demand for space within our marine landscape is increasing, and interactions are inevitable. A semi structured interview was conducted with forty fishers across the UK to elicit further information on the challenges, barriers to progress and priority issues these fishers face in relation to MRE development. The questionnaire also included a fisher assessment of the mitigation agenda developed by de Groot et al. (2014) under the Natural Environment Research Council Marine Renewable Energy Knowledge Exchange Programme ( NERC MREKEP). Qualitative data were extracted and analysed using the text analysis software NVivo8. Fishers identified barriers to progress, and in order of the most important themes included; policy, consultation, trust, lack of knowledge, true representation of all fishers, science vs. fisher observation mismatch and timescales. Priority issues identified in order of importance were; displacement or loss of access, cable disturbance, timings of installation/repairs, effects on the seabed and specifically offshore windfarm (OWF) sitting. The consultation process caused discontent among all fishers interviewed. In relation to working towards a collaborative mitigation agenda, fishers highlighted issues of trust in relation to; trans-boundary management, data management and the consultation process. At all stages of the research, the response rate of the importance of gathering fishers' knowledge (FK) was high. Fishers underlined the importance of this data source in assessing the impacts of MRE on the sectors of the UK fleet. Thus, although at an early stage of development, an initial framework for the

    The Osage Nation of northeastern Oklahoma, conterminous with Osage County, is characterized by gently rolling uplands and incised stream valleys that have downcut into underlying sedimentary rock units of Pennsylvanian through Permian age. Cattle ranching and petroleum and natural-gas extraction are the principal land uses in this rural area. Freshwater resources in the Osage Nation include water flowing in the Arkansas River and several smaller streams, water stored in several lakes, and groundwater contained in unconsolidated alluvial aquifers and bedrock aquifers. The Vamoosa-Ada aquifer is the primary source of fresh groundwater in this area. Fresh groundwater is underlain by saline groundwater in aquifers underlying the Osage Nation. Because of the potential for future population increases, demands for water from neighboring areas such as the Tulsa metropolitan area, and expansion of petroleum and natural-gas extraction on water resources of this area, the U.S. Geological Survey, in cooperation with the Osage Nation, summarized existing hydrologic data and identified data gaps to provide information for planning of future development of water resources in the Osage Nation. Streamflows in the Osage Nation are substantially affected by precipitation. During the relatively wet periods from the 1970s to 2000, the annual streamflows in the Osage Nation increased by as much as a factor of 2 relative to preceding decades, with subsequent decreases in streamflow of as much as 50 percent being recorded during intermittent drier years of the early 2000s. This report summarizes hydrologic data from 3 surface-water sites and 91 wells distributed across the Osage Nation. Data collected at those sites indicate that surface water in the Osage Nation generally has sufficient dissolved oxygen for survival of both coldwater and warmwater aquatic biota. Total dissolved solids concentration exceeded the secondary drinking-water standard of 500 milligrams per liter (mg/L) in up to

    Plastic contamination is an increasing environmental problem in marine systems where it has spread globally to even the most remote habitats. Plastic pieces in smaller size scales, microplastics (particles microplastic presence and interactions are equally as far reaching as are being observed in marine systems. Microplastics are being detected in freshwaters of Europe, North America, and Asia, and the first organismal studies are finding that freshwater fauna across a range of feeding guilds ingest microplastics. Drawing from the marine literature and these initial freshwater studies, we review the issue of microplastics in freshwater systems to summarise current understanding, identify knowledge gaps and suggest future research priorities. Evidence suggests that freshwater systems may share similarities to marine systems in the types of forces that transport microplastics (e.g. surface currents); the prevalence of microplastics (e.g. numerically abundant and ubiquitous); the approaches used for detection, identification and quantification (e.g. density separation, filtration, sieving and infrared spectroscopy); and the potential impacts (e.g. physical damage to organisms that ingest them, chemical transfer of toxicants). Differences between freshwater and marine systems include the closer proximity to point sources in freshwaters, the typically smaller sizes of freshwater systems, and spatial and temporal differences in the mixing/transport of particles by physical forces. These differences between marine and freshwater systems may lead to differences in the type of microplastics present. For example, rivers may show a predictable pattern in microplastic characteristics (size, shape, relative abundance) based on waste sources (e.g. household vs. industrial) adjacent to the river, and distance downstream from a point source. Given that the study of microplastics in freshwaters has only arisen in the last few years, we are still limited in our understanding of 1

    The importance of promoting gender equality and human rights in sexual and reproductive health (SRH) programmes and policies has been affirmed in numerous international and regional agreements, most recently the 2030 Agenda for Sustainable Development. Given the critical role of research to determine what works, we aimed to identify research gaps as part of a broader priority setting exercise on integrating gender equality and human rights approaches in SRH programmes and policies. A systematic literature review of reviews was conducted to examine the question: what do we know about how research in the context of SRH programmes and policies has addressed gender equality and human rights and what are the current gaps in research. We searched three databases for reviews that addressed the research question, were published between 1994–2014, and met methodological standards for systematic reviews, qualitative meta-syntheses and other reviews of relevance to the research question. Additional grey literature was identified based on expert input. Articles were appraised by the primary author and examined by an expert panel. An abstraction and thematic analysis process was used to synthesize findings. Of the 3,073 abstracts identified, 56 articles were reviewed in full and 23 were included along with 10 from the grey literature. The majority focused on interventions addressing gender inequalities; very few reviews explicitly included human rights based interventions. Across both topics, weak study designs and use of intermediate outcome measures limited evidence quality. Further, there was limited evidence on interventions that addressed marginalized groups. Better quality studies, longer-term indicators, and measurement of unintended consequences are needed to better understand the impact of these types of interventions on SRH outcomes. Further efforts are needed to cover research on gender equality and human rights issues as they pertain to a broader set of SRH topics

    Approximately 50 % of HIV-1 seropositive individuals develop HIV-1 associated neurocognitive disorders (HAND), which commonly include alterations in executive functions, such as inhibition, set shifting, and complex problem solving. Executive function deficits in HIV-1 are fairly well characterized, however, relatively few studies have explored the elemental dimensions of neurocognitive impairment in HIV-1. Deficits in temporal processing, caused by HIV-1, may underlie the symptoms of impairment in higher level cognitive processes. Translational measures of temporal processing, including cross-modal prepulse inhibition (PPI), gap-prepulse inhibition (gap-PPI), and gap threshold detection, were studied in mature (ovariectomized) female HIV-1 transgenic (Tg) rats, which express 7 of the 9 HIV-1 genes constitutively throughout development. Cross-modal PPI revealed a relative insensitivity to the manipulation of interstimulus interval (ISI) in HIV-1 Tg animals in comparison to control animals, extending previously reported temporal processing deficits in HIV-1 Tg rats to a more advanced age, suggesting the permanence of temporal processing deficits. In gap-PPI, HIV-1 Tg animals exhibited a relative insensitivity to the manipulation of ISI in comparison to control animals. In gap-threshold detection, HIV-1 Tg animals displayed a profound differential sensitivity to the manipulation of gap duration. Presence of the HIV-1 transgene was diagnosed with 91.1 % accuracy using gap threshold detection measures. Understanding the generality and permanence of temporal processing deficits in the HIV-1 Tg rat is vital to modeling neurocognitive deficits observed in HAND and provides a key target for the development of a diagnostic screening tool.

    Gap junctions are essential to the function of multicellular animals, which require a high degree of coordination between cells. In vertebrates, gap junctions comprise connexins and currently 21 connexins are known in humans. The functions of gap junctions are highly diverse and include exchange of metabolites and electrical signals between cells, as well as functions, which are apparently unrelated to intercellular communication. Given the diversity of gap junction physiology, regulation of gap junction activity is complex. The structure of the various connexins is known to some extent; and structural rearrangements and intramolecular interactions are important for regulation of channel function. Intercellular coupling is further regulated by the number and activity of channels present in gap junctional plaques. The number of connexins in cell-cell channels is regulated by controlling transcription, translation, trafficking, and degradation; and all of these processes are under strict control. Once in the membrane, channel activity is determined by the conductive properties of the connexin involved, which can be regulated by voltage and chemical gating, as well as a large number of posttranslational modifications. The aim of the present article is to review our current knowledge on the structure, regulation, function, and pharmacology of gap junctions. This will be supported by examples of how different connexins and their regulation act in concert to achieve appropriate physiological control, and how disturbances of connexin function can lead to disease. © 2012 American Physiological Society.

    2017-01-01

    The global prevalence and impact of diabetes has increased dramatically, particularly in sub-Saharan Africa. This region faces unique challenges in combating the disease including lack of funding for noncommunicable diseases, lack of availability of studies and guidelines specific to the population, lack of availability of medications, differences in urban and rural patients, and inequity between public and private sector health care. Because of these challenges, diabetes has a greater impact on morbidity and mortality related to the disease in sub-Saharan Africa than any other region in the world. In order to address these unacceptably poor trends, contextualized strategies for the prevention, identification, management, and financing of diabetes care within this population must be developed. This narrative review provides insights into the policy landscape, epidemiology, pathophysiology, care protocols, medication availability, and health care systems to give readers a comprehensive summary of many factors in these domains as they pertain to diabetes in sub-Saharan Africa. In addition to providing a review of the current evidence available in these domains, potential solutions to address the major gaps in care will be proposed to reverse the negative trends seen with diabetes in sub-Saharan Africa.

    In accordance with the WHO definition of health, this article examines the alarming discord between the epidemiology of hypertension, type 2 diabetes mellitus (T2DM), and obesity and the low profile of noninvasive (nondrug) compared with invasive (drug) interventions with respect to their prevention, reversal and management. Herein lies the ultimate knowledge translation gap and challenge in 21st century health care. Although lifestyle modification has long appeared in guidelines for medically managing these conditions, this evidence-based strategy is seldom implemented as rigorously as drug prescription. Biomedicine focuses largely on reducing signs and symptoms; the effects of the problem rather than the problem. This article highlights the evidence-based rationale supporting prioritizing the underlying causes and contributing factors for hypertension and T2DM, and, in turn, obesity. We argue that a primary focus on maximizing health could eliminate all three conditions, at best, or, at worst, minimize their severity, complications, and medication needs. To enable such knowledge translation and maximizing health outcome, the health care community needs to practice as an integrated team, and address barriers to effecting maximal health in all patients. Addressing the ultimate knowledge translation gap, by aligning the health care paradigm to 21st century needs, would constitute a major advance.

    The U.S. Department of Veterans Affairs (VA) Veteran Health Information Exchange (VHIE, formerly Virtual Lifetime Electronic Record, or VLER) had been deployed at all VA sites and used to exchange clinical information with private sector healthcare partners nationally. This paper examined VHIE's effect on allergy documentation. Review of all inbound VHIE transactions in FY14 showed that VHIE use was associated with a nearly eight-fold increase in allergy documentation rate. Preliminary manual document review further showed that VA and partners had shared knowledge of only 38% ofpatient allergies, while VA had exclusive knowledge of another 58% ofpatient allergies, and partners had exclusive knowledge of the last 5% of patient allergies. To our knowledge, this is the first study that examined the effect of HIE on allergy documentation.

    Full Text Available Abstract Background Identification of transcription factors (TFs involved in a biological process is the first step towards a better understanding of the underlying regulatory mechanisms. However, due to the involvement of a large number of genes and complicated interactions in a gene regulatory network (GRN, identification of the TFs involved in a biology process remains to be very challenging. In reality, the recognition of TFs for a given a biological process can be further complicated by the fact that most eukaryotic genomes encode thousands of TFs, which are organized in gene families of various sizes and in many cases with poor sequence conservation except for small conserved domains. This poses a significant challenge for identification of the exact TFs involved or ranking the importance of a set of TFs to a process of interest. Therefore, new methods for recognizing novel TFs are desperately needed. Although a plethora of methods have been developed to infer regulatory genes using microarray data, it is still rare to find the methods that use existing knowledge base in particular the validated genes known to be involved in a process to bait/guide discovery of novel TFs. Such methods can replace the sometimes-arbitrary process of selection of candidate genes for experimental validation and significantly advance our knowledge and understanding of the regulation of a process. Results We developed an automated software package called TF-finder for recognizing TFs involved in a biological process using microarray data and existing knowledge base. TF-finder contains two components, adaptive sparse canonical correlation analysis (ASCCA and enrichment test, for TF recognition. ASCCA uses positive target genes to bait TFS from gene expression data while enrichment test examines the presence of positive TFs in the outcomes from ASCCA. Using microarray data from salt and water stress experiments, we showed TF-finder is very efficient in recognizing

    Guideline-adherent treatment is associated with improved prognosis in atrial fibrillation (AF) patients but is insufficiently implemented in clinical practice. The European Society of Cardiology (ESC) performed a multinational educational needs assessment study among cardiologists, general practitioners/family physicians (GPs/FPs), and neurologists in order to evaluate knowledge and skills of physicians and system factors related to AF care delivery. A total of 561 physicians (294 cardiologists, 131 neurologists, and 136 GPs/FPs) from six European countries participated. This mixed-methods study included exploratory semi-structured qualitative interviews (n = 30) and a quantitative survey that included two clinical cases (n = 531). We identified eight key knowledge gaps and system barriers across all domains of AF care. A majority across all specialties reported skills needing improvement to classify AF pathophysiologically, rather than based on duration of episodes, and reported lack of availability of long-term electrocardiogram recording. Skills interpreting the CHA2DS2-VASc and the HAS-BLED scores were reported as needing improvement by the majority of neurologists (52% and 60%, respectively) and GPs/FPs (65% and 74%). Cardiologists calculated the CHA2DS2-VASc and HAS-BLED scores in 94%/70% in a presented case patient, but only 60%/49% of neurologists and 58%/42% of GPs/FPs did. There was much uncertainty on how to deal with anticoagulant therapy in complex patients. There was also a high disparity in using rate or rhythm control strategies, and indications for ablation. Information delivery to patients and communication between different specialties was often considered suboptimal, while national regulations and restrictions often hamper international guideline implementation. We identified major gaps in physicians' knowledge and skills across all domains of AF care, as well as system factors hampering guideline-compliant care implementation and

    Sales of energy drinks in the United States reached $12.5 billion in 2012. Emergency department visits related to consumption of these products have increased sharply, and while these numbers remain small relative to product sales, they raise important questions regarding biological and behavioral effects. Although some common ingredients of energy drinks have been extensively studied (e.g., caffeine, B vitamins, sugars, inositol), data on other ingredients (e.g., taurine) are limited. Summarized here are data presented elsewhere in this issue on the prevalence and patterns of caffeine-containing energy drink use, the effects of these products on alertness, fatigue, cognitive functions, sleep, mood, homeostasis, as well as on exercise physiology and metabolism, and the biological mechanisms mediating the observed effects. There are substantial data on the effects of some energy drink ingredients, such as caffeine and sugars, on many of these outcomes; however, even for these ingredients many controversies and gaps remain, and data on other ingredients in caffeine-containing energy drinks, and on ingredient interactions, are sparse. This summary concludes with a discussion of critical gaps in the data and potential next steps. Published 2014. This article is a U.S. Government work and is in the public domain in the USA.

    We investigated the current level of knowledge of Chinese heart failure (HF) guidelines among physicians, as a reference for the promotion and transformation of HF knowledge. Physicians from 88 hospitals in 27 provinces of China completed our survey between July and December 2014. The questions covered the main points included in the Chinese HF diagnosis and treatment guidelines (2014). A total of 2146 physicians, aged 20 to 62 years (35.6 ± 7.6 years), completed the survey. The correctness rate of their answers to the 15 multiple-choice questions in the HF questionnaire was generally low (mean 32.6%). The mean correctness rate for 10 blank-filling questions about the target doses of angiotensin-converting enzyme inhibitors, angiotensin II receptor antagonists, and β-blockers was 42.5%. On the basis of their responses, physicians whose knowledge of the guidelines was "excellent," "good," "medium," and "bad" accounted for 1.1%, 11.4%, 14.2%, and 73.4%, respectively. Physicians who possessed a higher level of qualifications had significantly greater awareness of HF guidelines than those with relatively low qualifications (P knowledge about HF. There is a need to improve physicians' education about HF in China.

    To describe the methodology used by the Reassessment Campaign on Veterinary Resuscitation (RECOVER) to evaluate the scientific evidence relevant to small animal CPR and to compose consensus-based clinical CPR guidelines for dogs and cats. This report is part of a series of 7 articles on the RECOVER evidence and knowledge gap analysis and consensus-based small animal CPR guidelines. It describes the organizational structure of RECOVER, the evaluation process employed, consisting of standardized literature searches, the analysis of relevant articles according to study design, species and predefined quality markers, and the drafting of clinical CPR guidelines based on these data. Therefore, this article serves as the methodology section for the subsequent 6 RECOVER articles. Academia, referral practice. RECOVER is a collaborative initiative that systematically evaluated the evidence on 74 topics relevant to small animal CPR and generated 101 clinical CPR guidelines from this analysis. All primary contributors were veterinary specialists, approximately evenly split between academic institutions and private referral practices. The evidence evaluation and guideline drafting processes were conducted according to a predefined sequence of steps designed to reduce bias and increase the repeatability of the findings, including multiple levels of review, culminating in a consensus process. Many knowledge gaps were identified that will allow prioritization of research efforts in veterinary CPR. Collaborative systematic evidence review is organizationally challenging but feasible and effective in veterinary medicine. More experience is needed to refine the process. © Veterinary Emergency and Critical Care Society 2012.

    Although the majority of travel-associated communicable diseases can be prevented, the public health burden of these diseases remains significant. Relatively little is known about how travelers know and perceive the health risks associated with travel and how they utilize preventive measures before and while traveling abroad. This study was conducted to determine the level of the knowledge, attitudes, and practices (KAP) of Muscat International Airport travelers about travel health in order to assess the knowledge gap and the need for travel health services in Oman. A cross-sectional study was conducted over a period of 1week using a self-administered questionnaire. The overall level of knowledge about vaccine-preventable diseases, food safety, and preventive measures against insect bites of the participants was inadequate. The practice concerning preventive travel health measures, such as the use of specific immunizations and antimalarial prophylaxis, was very limited, and influenced by some personal and travel-related factors. The inadequate level of travelers' knowledge and poor utilization of travel medicine services highlights the need for the provisions of specialized travel medicine services at the national level and to develop educational materials promoting the importance of pre-travel health advice.

    2014-02-01

    This article constructs a map on the translation of knowledge concerning cervical cancer, based on citation networks analysis and the use of Gene Ontology terms and Medical Subject Headings. We identified two areas of research that are poorly interconnected and differ in structure, content, and evolution. One focuses on causes of cancer and the other on patient care. The first research area showed a knowledge translation process where basic research and clinical research are communicated through a set of articles that consolidate human papillomavirus infection as the necessary cause of cervical cancer. The first area aims to prevent HPV infection and the development of cervical cancer, while the second aims to stage and treat the disease.

    Full Text Available Abstract Background ParticipACTION was a pervasive communication campaign that promoted physical activity in the Canadian population for three decades. According to McGuire's hierarchy-of-effects model (HOEM, this campaign should influence physical activity through intermediate mediators such as beliefs and intention. Also, when such media campaigns occur, knowledge gaps often develop within the population about the messages being conveyed. The purposes of this study were to (a determine the current awareness of ParticipACTION campaigns among Canadians; (b confirm if awareness of the ParticipACTION initiative varied as a function of levels of education and household income; and, (c to examine whether awareness of ParticipACTION was associated with physical activity related beliefs, intentions, and leisure-time physical activity (LTPA as suggested by the HOEM. Specifically, we tested a model including awareness of ParticipACTION (unprompted, prompted, outcome expectations, self-efficacy, intention, and physical activity status. Methods A population-based survey was conducted on 4,650 Canadians over a period of 6 months from August, 2007 to February, 2008 (response rate = 49%.

    Although the gender gap in math course-taking and performance has narrowed in recent decades, females continue to be underrepresented in math-intensive fields of Science, Technology, Engineering, and Mathematics (STEM). Career pathways encompass the ability to pursue a career as well as the motivation to employ that ability. Individual differences in cognitive capacity and motivation are also influenced by broader sociocultural factors. After reviewing research from the fields of psychology, sociology, economics, and education over the past 30 years, we summarize six explanations for US women's underrepresentation in math-intensive STEM fields: (a) cognitive ability, (b) relative cognitive strengths, (c) occupational interests or preferences, (d) lifestyle values or work-family balance preferences, (e) field-specific ability beliefs, and (f) gender-related stereotypes and biases. We then describe the potential biological and sociocultural explanations for observed gender differences on cognitive and motivational factors and demonstrate the developmental period(s) during which each factor becomes most relevant. We then propose evidence-based recommendations for policy and practice to improve STEM diversity and recommendations for future research directions.

    Mounting evidence supports health and well-being benefits associated with nature experiences, while also highlighting race- and class-based inequalities in access and exposure. We synthesized the literature on nature contact by Latinos in the United States to assess the state of knowledge and strategically identify research needs to improve outcomes and reduce health disparities for this rapidly growing ethnic group. Our systematic review revealed 108 articles with a notable increase in number of papers over the past 3 decades. We noted that the body of research is focused on certain demographic targets (adults in urban areas) with a relative dearth of knowledge for others (children, seniors, and rural areas). Our analysis also revealed strong compartmentalizing of studies into research “clusters” based on nonoverlapping topics and types of outcomes that are measured. Although one-third of studies explored health outcomes, these studies rarely examined other outcomes or research topics. Moreover, less than 7% of studies reported on interventions. Given the potential for nature contact to enhance health and well-being, there is substantial need for multidisciplinary research that explores interactions between social, cultural, and economic factors, and how those ultimately relate to nature contact and outcomes for Latinos in the United States.

    To identify the knowledge and skill needs of oncology nurse practitioners (ONPs) as they enter cancer care practice, and to identify necessary educational resources. Cross-sectional, descriptive. A national e-mail survey. 610 self-described ONPs from the Oncology Nursing Society's database. The project team developed a 28-item electronic survey. The survey was randomly distributed via e-mail. ONPs' feelings of preparedness in the first year of ONP practice. In the first year of practice, 90% of ONPs rated themselves as prepared or very prepared in obtaining patient history, performing physical examination, and documenting findings. ONPs rated themselves as not at all or somewhat prepared in clinical issues of chemotherapy/biotherapy competency (n = 81, 78%), recognizing and managing oncologic emergencies, (n = 77, 70%), and recognizing and managing drug toxicities (n = 63, 61%). The primary source of oncology education for ONPs new to practice was almost exclusively the collaborating or supervising physician (n = 84, 81%). Specific knowledge and skills, such as information about chemotherapy, oncologic emergencies, and side effects of therapy, are needed before an ONP enters a cancer care practice. Cancer-specific education should be made available to new ONPs as they begin independent practice.

    Maternal safety through pertussis vaccination and subsequent maternal–fetal-antibody transfer are well documented, but information on infant protection from pertussis by such antibodies and by subsequent vaccinations is scarce. Since mice are used extensively for maternal-vaccination studies, we adopted that model to narrow those gaps in our understanding of maternal pertussis immunization. Accordingly, we vaccinated female mice with commercial acellular pertussis (aP) vaccine and measured offspring protection against Bordetella pertussis challenge and specific-antibody levels with or without revaccination. Maternal immunization protected the offspring against pertussis, with that immune protection transferred to the offspring lasting for several weeks, as evidenced by a reduction (4–5 logs, p protection to offspring up to the fourth pregnancy. Under the conditions of our experimental protocol, protection to offspring from the aP-induced immunity is transferred both transplacentally and through breastfeeding. Adoptive-transfer experiments demonstrated that transferred antibodies were more responsible for the protection detected in offspring than transferred whole spleen cells. In contrast to reported findings, the protection transferred was not lost after the vaccination of infant mice with the same or other vaccine preparations, and conversely, the immunity transferred from mothers did not interfere with the protection conferred by infant vaccination with the same or different vaccines. These results indicated that aP-vaccine immunization of pregnant female mice conferred protective immunity that is transferred both transplacentally and via offspring breastfeeding without compromising the protection boostered by subsequent infant vaccination. These results—though admittedly not necessarily immediately extrapolatable to humans—nevertheless enabled us to test hypotheses under controlled conditions through detailed sampling and data collection.

    The purpose of this article is to publicize an important new Web-based educational program. Recognizing the growing gap in psychiatric-mental health knowledge and the need to better prepare new graduates and nurses transitioning from other service lines into psychiatric inpatient nursing settings, the American Psychiatric Nurses Association developed a 15-hour, modularized curriculum to provide foundational psychiatric-mental health knowledge. This modularized curriculum, called American Psychiatric Nurses Association Transitions in Practice (ATP) focuses on the knowledge and skills to insure the success of nurses new to psychiatric-mental health nursing settings and to improve the overall care for persons with mental health and substance use disorders. The ATP program is also proving to be useful content for nurses in emergency departments, hospitals, and other health settings to improve their care of patients with psychiatric and mental health needs. A summary of the program modules and a toolkit with suggested measures for nurses, patients, and agency outcomes is described. Feedback from participants completing the ATP program within the first 6 months is overwhelmingly positive and holds promise for widespread application across a variety of health care settings.

    In the field of stem cell biology and diabetes, we and others seek to derive mature and functional human pancreatic β cells for disease modeling and cell replacement therapy. Traditionally, knowledge gathered from rodents is extended to human pancreas developmental biology research involving human pluripotent stem cells (hPSCs). While much has been learnt from rodent pancreas biology in the early steps toward Pdx1(+) pancreatic progenitors, much less is known about the transition toward Ngn3(+) pancreatic endocrine progenitors. Essentially, the later steps of pancreatic β cell development and maturation remain elusive to date. As a result, the most recent advances in the stem cell and diabetes field have relied upon combinatorial testing of numerous growth factors and chemical compounds in an arbitrary trial-and-error fashion to derive mature and functional human pancreatic β cells from hPSCs. Although this hit-or-miss approach appears to have made some headway in maturing human pancreatic β cells in vitro, its underlying biology is vaguely understood. Therefore, in this mini-review, we discuss some of these late-stage signaling pathways that are involved in human pancreatic β cell differentiation and highlight our current understanding of their relevance in rodent pancreas biology. Our efforts here unravel several novel signaling pathways that can be further studied to shed light on unexplored aspects of rodent pancreas biology. New investigations into these signaling pathways are expected to advance our knowledge in human pancreas developmental biology and to aid in the translation of stem cell biology in the context of diabetes treatments.

Chan School of Public Health, Boston, MA, USA Background: Although the patient-centered medical home (PCMH model is considered important for the future of primary care in the USA, it remains unclear how best to prepare trainees for PCMH practice and leadership. Following a baseline study, the authors added a new required PCMH block rotation and resident team to an existing longitudinal PCMH immersion and didactic curriculum within a Level 3-certified PCMH, aiming for “enhanced situated learning”. All 39 residents enrolled in a USA family medicine residency program during the first year of curricular implementation completed this new 4-week rotation. This study examines the effects of this rotation after 1 year. Methods: A total of 39 intervention and 13 comparison residents were eligible participants. This multimethod study included: 1 individual interviews of postgraduate year (PGY 3 intervention vs PGY3 comparison residents, assessing residents’ PCMH attitudes, knowledge, and clinical experience, and 2 routine rotation evaluations. Interviews were audiorecorded, transcribed, and analyzed using immersion/crystallization. Rotation evaluations were analyzed using descriptive statistics and qualitative analysis of free text responses. Results: Authors analyzed 23 interviews (88% and 26 rotation evaluations (67%. Intervention PGY3s’ interviews revealed more nuanced understanding of PCMH concepts and more experience with system-level PCMH

    Full Text Available PURPOSE: Identify epilepsy-associated factors and calculate measures of impact, stigma, quality of life (QOL, knowledge-attitude-practice (KAP and treatment gap in Prey Veng, Cambodia. METHODS: This first Cambodian population-based case-control study had 96 epileptologist-confirmed epilepsy cases and 192 randomly selected matched healthy controls. Standard questionnaires, which have been used in similar settings, were used for collecting data on various parameters. Univariate and multivariate regression was done to determine odds ratios. Jacoby stigma, 31-item QOL, KAP etc were determined and so were the factors associated with them using STATA software. Treatment gap was measured using direct method. KEY FINDINGS: Multivariate analyses yielded family history of epilepsy, difficult or long delivery, other problems beside seizures (mainly mental retardation, hyperthermia, and eventful pregnancy of the subject's mother as factors associated with epilepsy. There was high frequency of seizure precipitants esp. those related to sleep. Population attributable risk (% was: family history (15.0, eventful pregnancy of subject's mother (14.5, long/difficult birth (6.5, and other problem beside seizures (20.0. Mean stigma (1.9±1.1, on a scale of 3 was mainly related to treatment efficacy. Mean QOL (5.0±1.4 on a scale of 10 was mainly related to treatment regularity. Cause or risk factor could be determined in 56% of cases. Treatment gap was 65.8%. SIGNIFICANCE: Factors in pre- and perinatal period were found to be most crucial for epilepsy risk in Cambodia which inturn provides major prevention opportunities. A global action plan for treatment, stigma reduction and improvement of QOL should be set-up in this country.

We advocate for the development and validation of robust field and point of care diagnostic tools that are more sensitive, specific and cost effective for use in ZIKV epidemics and routine pathophysiology surveillance and monitoring systems as an imperative avenue in understanding Zika-related and other arbovirus trends and apply genomic and proteomic characterisation approaches in guiding annotation efforts in order to design and implement public health burden mitigation and adaptation strategies.

    On February 1, 2016, the World Health Organization declared that the cluster of microcephaly cases and other neurological disorders constitute public health emergency of international concern. Furthermore, few studies demonstrated that there was an increased evidence of causal relationship of Zika virus (ZIKAV) infection and micro-cephaly, birth abnormalities and neurological disorders such as Guillain–Barr ´e syndrome. ZIKAV transmission occurs mainly by the bite of infected mosquitos (Aedes species), but there are also reports that infections could occur via the placenta, breast milk, saliva, blood transfusion and sex. This article reviews the global efforts, progress in scientific research to understand the pathogenesis of ZIKAV infection & disease, clinical pre-sentations, congenital transmission and autoimmune neurological disorders. The paper further explores the knowledge gaps, future priority research agenda for strategic response including vector control and prevention. We conducted a systematic literature review to synthesise available evidence on ZIKAV infection and its vector and host interaction from electronic databases.

    We developed a communication instrument to be used in the Emergency Department (ED) and hypothesized that use of this guide would increase patient comprehension of and satisfaction with care. This multi-site trial enrolled 643 patients in treatment and control groups. Comprehension of care was assessed by chart review and satisfaction measured via validated survey. Use of the instrument was not associated with improvements in patient knowledge about their care, with a mean of 4.6 (95% CI: 4.8-5.8) comprehension defects in the control group and 4.4 (95% CI: 3.9-4.9) in the treatment group. There was no significant effect on patient satisfaction 76.4% versus 76.9%, p=0.34. Elderly patients in both groups were found to have 1.1 (ppatients. Patients frequently misunderstand medical care in the ED. Comprehension decreases with increasing age. An isolated communication instrument does not improve satisfaction with or understanding of the care received. Providing a structured place for providers and patients to record details of care does not seem to improve satisfaction with or comprehension of care. Interventions that focus on communication skills and face time with patients may prove more effective. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    Scientific knowledge in international relations has generally focused on an epistemological distinction between rationalism and reflectivism over the last 25 years. This chapter argues that this distinction has created a double distinction between theory/reality and theory/practice, which works...... and reflectivism. Bourdieu, on the contrary, lets the challenge to the theory/reality distinction spill over into a challenge to the theory/practice distinction by thrusting the scientist in the foreground as not just a factor (discourse/genre) but as an actor. In this way, studies of IR need to include a focus...... as a ghost distinction structuring IR research. While reflectivist studies have emphasised the impossibility of detached, objective knowledge production through a dissolution of the theory/reality distinction, the theory/practice distinction has been left largely untouched by both rationalism...

    The bushmeat industry has been a topic of increasing importance among public health officials for its influence on zoonotic diseases transmission, such as Ebola virus disease (EVD), a rare and severe infectious disease of humans and non-human primates. This survey assessed knowledge/awareness, risk perceptions and mitigation practices towards EVD among bushmeat handlers in north-central Nigeria. These characteristics are premise to level of preparedness against appropriate risk prevention and control. A questionnaire-based cross-sectional study was conducted between January and December 2015 on 395 bushmeat handlers. Descriptive and analytical statistical analyses were performed using Epi-Info 3.5.3 software, and p knowledge than the hunters. Handlers with tertiary education were more likely (OR 3.22; 95% CI: 1.56-6.67) to possess significant satisfactory knowledge/awareness about EVD. Also, vendors were more likely (OR 1.85; 95% CI: 1.01-3.42) to practice satisfactory mitigation measures than the hunters. Only handlers with tertiary education were more likely (OR 2.48; 95% CI: 1.26-4.89) to significantly practice satisfactory mitigation measures against EVD. Although most of the handlers possessed significant knowledge/awareness about EVD, few applied mitigation measures against its infection, which is the challenging gap. There is a need for collaborations between the public health, veterinary and wildlife authorities in the provision of health information to bushmeat handlers on better management of emerging and re-emerging zoonotic viral diseases of wildlife origin. © 2017 Blackwell Verlag GmbH.

    Curricula changes in physical therapist education programs in Canada emphasize evidence-based practice skills, including literature retrieval and evaluation. Do graduates use these skills in practice? The aim of this study was to evaluate the use of research information in the clinical decision making of therapists with different years of experience and evidence-based practice preparation. Perceptions about evidence-based practice were explored qualitatively. A cross-sectional study with 4 graduating cohorts was conducted. Eighty physical therapists representing 4 different graduating cohorts participated in interviews focused on 2 clinical scenarios. Participants had varying years of clinical experience (range=1-15 years) and academic knowledge of evidence-based practice skills. Therapists discussed the effectiveness of interventions related to the scenarios and identified the sources of information used to reach decisions. Participants also answered general questions related to evidence-based practice knowledge. Recent graduates demonstrated better knowledge of evidence-based practice skills compared with therapists with 6 to 15 years of clinical experience. However, all groups used clinical experience most frequently as their source of information for clinical decisions. Research evidence was infrequently included in decision making. This study used a convenience sample of therapists who agreed to volunteer for the study. The results suggest a knowledge-to-practice gap; graduates are not using the new skills to inform their practice. Tailoring academic evidence-based activities more to the time constraints of clinical practice may help students to be more successful in applying evidence in practice. Academic programs need to do more to create and nurture environments in both academic and clinical settings to ensure students practice using evidence-based practice skills across settings. © 2015 American Physical Therapy Association.

    Global environmental changes and other anthropogenic impacts are rapidly transforming the structure and functioning of ecosystems worldwide. These changes are leading to land degradation with an estimated 25 % of the global land surface being affected. Landscape-scale restoration of these degraded ecosystems has therefore been recognised globally as an international priority. In the resource-rich biodiverse semi-arid Pilbara region of north-west Western Australia hundreds of thousands of hectares are disturbed due to established and emerging iron-ore mine operations. At this scale, the need to develop cost-effective large-scale solutions to restore these landscapes becomes imperative to preserve biodiversity and achieve functionality and sustainability of these ecosystems. The Restoration Seedbank Initiative (RSB) (http://www.plants.uwa.edu.au/ research/restoration-seedbank-initiative) is a five-year multidisciplinary research project that aims to build knowledge and design strategies to restore mine-impacted landscapes in the Pilbara and other arid and semi-arid landscapes worldwide (Kildiseheva et al., 2016). The RSB comprises four research programs that focus on seedbank management and curation, seed storage, seed enhancement, and the use of alternative soil substrates (soil or growing medium program) respectively. These multi-disciplinary programs address the significant challenges of landscape scale restoration in arid systems. In the soil program we follow an integrated approach that includes the characterization of undisturbed ecosystems, assessment of restored soils with the use of soil quality indicators, and design of alternative soil substrates to support the establishment of native plant communities. A series of glasshouse studies and field trials have been conducted in the last three years to advance our knowledge on soil limitations and to provide solutions to effectively overcome these challenges in arid ecosystem restoration. These studies include

    When compared to systemic administration, if used correctly inhalers deliver a smaller enough percent of the drug right to the site of action in the lungs, with a faster onset of effect and with reduced systemic availability that minimizes adverse effects. However, the health professionals' and patients' use of metered dose inhaler is poor. This study was aimed to explore community pharmacy professionals' (pharmacists' and druggists') competency on metered dose inhaler (MDI) technique. A cross sectional study was employed on pharmacy professionals working in community drug retail outlets in Gondar town, northwest Ethiopia from March to May 2017. Evaluation tool was originally taken and adapted from the National Asthma Education and Prevention Programmes of America (NAEPP) step criteria for the demonstration of a metered dose inhaler to score the knowledge/proficiency of using the inhaler. Among 70 community pharmacy professionals approached, 62 (32 pharmacists and 30 druggists/Pharmacy technicians) completed the survey with a response rate of 85.6%. Only three (4.8%) respondents were competent by demonstrating the vital steps correctly. Overall, only 13 participants got score seven or above, but most of them had missed the essential steps which included steps 1, 2, 5, 6, 7 or 8. There was a significant difference (P = 0.015) in competency of demonstrating adequate inhalational technique among respondents who took training on basic inhalational techniques and who did not. This study shown that, community pharmacy professionals' competency of MDI technique was very poor. So as to better incorporate community pharmacies into future asthma illness management and optimize the contribution of pharmacists, interventions would emphasis to improve the total competence of community pharmacy professionals through establishing and providing regular educational programs.

    The interplay between genetic susceptibilities and environmental exposures in the pathogenesis of a variety of diseases is an area of increased scientific, epidemiologic, and social interest. Given the variation in methodologies used in the field, this review aims to create a framework to help understand occupational exposures as they currently exist and provide a foundation for future inquiries into the biological mechanisms of the gene-environment interactions. Understanding of this complex interplay will be important in the context of occupational health, given the public health concerns surrounding a variety of occupational exposures. Studies found evidence that suggest genetics influence the progression of disease postberyllium exposure through genetically encoded major histocompatibility complex, class II, DP alpha 2 (HLA-DP2)-peptide complexes as it relates to T-helper cells. This was characterized at the molecular level by the accumulation of Be-responsive CD4 T cells in the lung, which resulted in posttranslational change in the HLA-DPB1 complex. These studies provide important evidence of gene-environment association, and many provide insights into specific pathogenic mechanisms. The following includes a review of the literature regarding gene-environment associations with a focus on pulmonary diseases as they relate to the workplace.

    Despite the availability of numerous evidence-based smoking prevention and cessation programs, many countries are still not implementing these research-proven programs. The primary aim of this paper is to summarize the extent to which evidence-based smoking control programs have been implemented in Croatia over the last two decades. Data from the systematic reviews of the Cochrane Tobacco Addiction Group, which are readily available worldwide, were used as criteria to evaluate whether effective, evidence-based programs have been implemented in Croatia. According to our findings, the most effective behavioral and pharmacological smoking cessation interventions have thus far been underutilized in Croatia. In addition, some interventions that have been continuously implemented in Croatia--such as using self-help materials, school-based programs and the celebration of World No Tobacco Day--have only small, short-term beneficial effects according to the Cochrane reviews. However, Croatia is a party to the World health Organization Framework Convention on Tobacco Control and therefore has effective national legislation on tobacco control. Croatia should develop and implement programs that integrate the existing high-quality empirical evidence on the effectiveness of various behavioral, pharmacological, and social interventions for smoking prevention and cessation. This programming should become a part of a continuous national strategy, and should be implemented throughout all of Croatia.

  14. Tropical Land Use Conversion Effects on Soil Microbial Community Structure and Function: Emerging Patterns and Knowledge Gaps

    Modifications in vegetation due to land use conversions (LUC) between primary forests, pasture, cropping systems, tree plantations, and secondary forests drive shifts in soil microbial communities. These microbial community alterations affect carbon sequestration, nutrient cycling, aboveground biomass, and numerous other soil processes. Despite their importance, little is known about soil microbial organisms' response to LUC, especially in tropical regions where LUC rates are greatest. This project identifies current trends and uncertainties in tropical soil microbiology by comparing 56 published studies on LUC in tropical regions. This review indicates that microbial biomass and functional groups shifted in response to LUC, supporting demonstrated trends in changing soil carbon stocks due to LUC. Microbial biomass was greatest in primary forests when compared to secondary forests and in all forests when compared to both cropping systems and tree plantations. No trend existed when comparing pasture systems and forests, likely due to variations in pasture fertilizer use. Cropping system soils had greater gram positive and less gram negative bacteria than forest soils, potentially resulting in greater respiration of older carbon stocks in agricultural soils. Bacteria dominated primary forests while fungal populations were greatest in secondary forests. To characterize changes in microbial communities resulting from land use change, research must reflect the biophysical variation across the tropics. A chi-squared test revealed that the literature sites represented mean annual temperature variation across the tropics (p-value=0.66).

    Exclusive breastfeeding (EBF) is rarely practiced despite its significant child survival benefits. A key constraint to increasing EBF rates in Zimbabwe and most of the developing world is that key decision makers (fathers/partners and other family members) are often poorly informed about EBF and do not attend antenatal clinics where health information is routinely provided. Informed by formative research, a district-wide campaign was conducted in rural Zimbabwe to encourage EBF and expressing and heat treating (EHT) breast milk as a means to maintain EBF. The campaign combined traditional strategies of education, counselling and outreach through health service delivery with a novel road show 'edutainment' intervention to reach men and other community members. A post campaign evaluation measured the association of road show exposure with 20 knowledge items and summative scores of social norms, beliefs and attitudes obtained through exploratory factor analysis. In adjusted models, road show exposure was associated with correct EBF knowledge (β=1.0, 0.001), EHT knowledge (β=1.3, Pbenefits of condom use during pregnancy and breastfeeding (β=0.5, P<0.001), and more positive EBF social norms (β=0.6, P<0.001), EBF beliefs and attitudes (β=1.0, P<0.001) and attitudes towards condom use during breastfeeding (β=0.6, P<0.001). Road show exposure was more strongly associated with EBF knowledge among men (P-value for gender×exposure group interaction=0.03), suggesting that it also closed the knowledge gap between men and women. Longitudinal studies will determine whether road shows were associated with changes in EBF practices. © 2011 Blackwell Publishing Ltd.

    Full Text Available Salmonella and Shiga toxin-producing Escherichia coli are two of the main causes of foodborne disease globally, and while they have been implicated as possible causes of foodborne disease within the Caribbean region, the actual incidence is unknown. Trinidad and Tobago, one of the larger countries in the Caribbean, has an estimated annual foodborne disease burden of over 100,000 cases and, similar to other countries, the etiology of most of these cases is unknown. Both pathogens can reside as part of the normal gastrointestinal microflora of many wild and domestic animals, with animals acting as reservoirs, spillover hosts, or dead-end hosts. Carriage in animal species can be asymptomatic or, in the case of Salmonella in particular, there may be clinical manifestation in animals, which resemble the disease seen in humans. In this review, we will focus on the epidemiology of these two foodborne pathogens in Trinidad and Tobago and identify any knowledge gaps in the published literature. The filling of this critical knowledge void is essential for the development and implementation of appropriate mechanisms to reduce the dissemination and transmission of these pathogens, not only in Trinidad and Tobago, but also in the wider Caribbean.

    Full Text Available The diagnosis of the current European societies, which are made possible through the production of scientific knowledge and technical, is simple in its formulation. They are societies in constant knowledge creation.  Given socio-economic and working conditions, implemented from the neo-liberal model of society, the abstract knowledge, associated with the profit of a few over the many, is leading the cultural logic of knowledge societies, without any axiological hesitation, That is to say, without postulating and discerning common goals and values ​​that can motivate human beings to live for the human journey. Thus, the current European societies, but not only them, are knowledge societies, (because they live in the continuous creation of technical and scientific knowledge. At the same time, companies are axiologically dismantled. They are societies that do not have been axiologically oriented. If humanity does not recover and increase this constitutive dimension, may not be feasible in human form. Our reflection presents a proposal for an axiological epistemology (M.

    In Germany, educational deficits or potential benefits involved in global health education have not been analysed till now. We assess the importance medical students place on learning about social determinants of health (SDH) and assess their knowledge of global health topics in relation to (i) mobility patterns, their education in (ii) tropical medicine or (iii) global health. Cross-sectional study among medical students from all 36 medical schools in Germany using a web-based, semi-structured questionnaire. Participants were recruited via mailing-lists of students' unions, all medical students registered in 2007 were eligible to participate in the study. We captured international mobility patterns, exposure to global health learning opportunities and attitudes to learning about SDH. Both an objective and subjective knowledge assessment were performed. 1126 online-replies were received and analysed. International health electives in developing countries correlated significantly with a higher importance placed on all provided SDH (p ≤ 0.006). Participation in tropical medicine (p educational system' (p = 0.007) and the 'health system structure' (p = 0.007), while the item 'politics' was marginally significant (p = 0.053).In the knowledge assessment students achieved an average score of 3.6 (SD 1.5; Mdn 4.0), 75% achieved a score of 4.0 or less (Q25 = 3.0; Q75 = 4.0) from a maximum achievable score of 8.0. A better performance was associated with international health electives (p = 0.032), participation in tropical medicine (p = 0.038) and global health (p = 0.258) courses. The importance medical students in our sample placed on learning about SDH strongly interacts with students' mobility, and participation in tropical medicine and global health courses. The knowledge assessment revealed deficits and outlined needs to further analyse education gaps in global health.

    Artemisinin combination therapy (ACT) has been the first-line treatment for uncomplicated malaria in Cameroon since 2004 and Nigeria since 2005, though many febrile patients receive less effective antimalarials. Patients often rely on providers to select treatment, and interventions are needed to improve providers' practice and encourage them to adhere to clinical guidelines. Providers' adherence to malaria treatment guidelines was examined using data collected in Cameroon and Nigeria at public and mission facilities, pharmacies and drug stores. Providers' choice of antimalarial was investigated separately for each country. Multilevel logistic regression was used to determine whether providers were more likely to choose ACT if they knew it was the first-line antimalarial. Multiple imputation was used to impute missing data that arose when linking exit survey responses to details of the provider responsible for selecting treatment. There was a gap between providers' knowledge and their practice in both countries, as providers' decision to supply ACT was not significantly associated with knowledge of the first-line antimalarial. Providers were, however, more likely to supply ACT if it was the type of antimalarial they prefer. Other factors were country-specific, and indicated providers can be influenced by what they perceived their patients prefer or could afford, as well as information about their symptoms, previous treatment, the type of outlet and availability of ACT. Public health interventions to improve the treatment of uncomplicated malaria should strive to change what providers prefer, rather than focus on what they know. Interventions to improve adherence to malaria treatment guidelines should emphasize that ACT is the recommended antimalarial, and it should be used for all patients with uncomplicated malaria. Interventions should also be tailored to the local setting, as there were differences between the two countries in providers' choice of antimalarial

    Shipping industry and seaborne trade have rapidly increased over the last fifty years, mainly due to the continuous increasing demand for chemicals and fuels. Consequently, despite current regulations, the occurrence of accidental spills poses an important risk. Hazardous and noxious substances (HNSs) have been raising major concern among environmental managers and scientific community for their heterogeneity, hazardous potential towards aquatic organisms and associated social-economic impacts. A literature review on ecotoxicological hazards to aquatic organisms was conducted for seven HNSs: acrylonitrile, n-butyl acrylate, cyclohexylbenzene, hexane, isononanol, trichloroethylene and xylene. Information on the mechanisms of action of the selected HNS was also reviewed. The main purpose was to identify: i) knowledge gaps in need of being addressed in future research; and ii) a set of possible biomarkers suitable for ecotoxicological assessment and monitoring in both estuarine and marine systems. Main gaps found concern the scarcity of information available on ecotoxicological effects of HNS towards marine species and their poorly understood mode of action in wildlife. Differences were found between the sensitivity of freshwater and seawater organisms, so endpoints produced in the former may not be straightforwardly employed in evaluations for the marine environment. The relationship between sub-individual effects and higher level detrimental alterations (e.g. behavioural, morphological, reproductive effects and mortality) are not fully understood. In this context, a set of biomarkers associated to neurotoxicity, detoxification and anti-oxidant defences is suggested as potential indicators of toxic exposure/effects of HNS in marine organisms. Overall, to support the development of contingency plans and the establishment of environmental safety thresholds, it will be necessary to undertake targeted research on HNS ecotoxicity in the marine environment.

    The diagnosis and management of glucose-6-phosphate dehydrogenase (G6PD) deficiency is a crucial aspect in the current phases of malaria control and elimination, which will require the wider use of 8-aminoquinolines for both reducing Plasmodium falciparum transmission and achieving the radical cure of Plasmodium vivax. 8-aminoquinolines, such as primaquine, can induce severe haemolysis in G6PD-deficient individuals, potentially creating significant morbidity and undermining confidence in 8-aminoquinoline prescription. On the other hand, erring on the side of safety and excluding large numbers of people with unconfirmed G6PD deficiency from treatment with 8-aminoquinolines will diminish the impact of these drugs. Estimating the remaining G6PD enzyme activity is the most direct, accessible, and reliable assessment of the phenotype and remains the gold standard for the diagnosis of patients who could be harmed by the administration of primaquine. Genotyping seems an unambiguous technique, but its use is limited by cost and the large range of recognized G6PD genotypes. A number of enzyme activity assays diagnose G6PD deficiency, but they require a cold chain, specialized equipment, and laboratory skills. These assays are impractical for care delivery where most patients with malaria live. Improvements to the diagnosis of G6PD deficiency are required for the broader and safer use of 8-aminoquinolines to kill hypnozoites, while lower doses of primaquine may be safely used to kill gametocytes without testing. The discussions and conclusions of a workshop conducted in Incheon, Korea in May 2012 to review key knowledge gaps in G6PD deficiency are reported here.

    Pulmonary hypertension complicates the clinical course of extremely preterm infants and is associated with bronchopulmonary dysplasia (BPD). However, prevalence, risk factors, and outcome of pulmonary hypertension in these infants are insufficiently known. This systematic review and meta-analysis aims to provide an up-to-date overview of available data on prevalence, risk factors, and outcome of pulmonary hypertension and to identify current knowledge gaps. Medline, EMBASE, and the Cochrane Library databases were searched in July 2017. Two authors reviewed titles/abstracts and full-texts. Eligible studies reported prevalence, patient characteristics or mortality of infants with/without pulmonary hypertension. Studies were excluded if they did not include extremely preterm infants. Only similar study samples (selected infants with BPD or infants both with/without BPD) were compared in the meta-analyses. Of 1829 unique articles identified, 25 were eligible for inclusion. Pulmonary hypertension was observed in infants with BPD (20%, 95% confidence interval [CI] 14, 25), but also in those without BPD (2%, 95% CI 0, 8). Infants with severe BPD were most at risk of pulmonary hypertension (risk ratio [RR] 2.7, 95% CI 1.7, 4.2). Infants with pulmonary hypertension were more at risk of mortality (RR 4.7, 95% CI 2.7, 8.3). Pulmonary hypertension occurs in particularly in infants with severe BPD, and increases risk of mortality. Due to selected study populations, heterogeneous pulmonary hypertension-definitions and poorly reported timing of pulmonary hypertension assessments, however, data available in current reports are insufficient to allow accurate assessment of true prevalence, risk factors, and time-related outcome. Prospective studies, with standardised methodology and follow-up are needed to determine these factors. © 2018 John Wiley & Sons Ltd.

    Mainly, due to new scientific inquiries and technological advancements Knowledge becomes obsolete. So it creates a dilemma where the applicability of so called theories and models which we learnt in class can still be applied to solve problems? Thus, the scholars bring the notion of RESEARCH as a definite solution which enriches the existing understanding of a phenomenon. This can be either a theory testing or a theory extension (theory building) approach. In fact, gap identification and form...

    should form the subject of further investigation. Traditional treatment for evil eye was often administered through nostrils, raising questions about its effectiveness. The narration given by the pastoralists in associating tick infestation with udder health problems was compatible with existing scientific evidences. In this respect, such local knowledge can be better utilized for the educational messages targeting control and management of tick infestation in livestock. However, the misperception of causes for acute udder swelling as evil eye can be problematic as far as the application of appropriate treatment and management of the problem is concerned. The misperception can significantly impact the welfare of animals and highlights the need for capacity building of the pastoralists on the causes and treatment of udder health problems.

  14. "Prince Charming Syndrome?" Gender gap in preferences for defined contribution pensions in Japan.

    Science.gov (United States)

    Watanabe, Satoshi P

    2017-01-01

    Using survey data collected by the Japan Institute of Life Insurance in 2002, this study finds that a significant gender gap existed in defined contribution (DC) pension knowledge among workers employed at small- to medium-sized private firms in Japan. Even with similar DC knowledge, however, men and women reveal different preferences for DC pensions, indicating that their perceptional responses may widely differ from actual behaviors. Apart from the knowledge gap, the result shows evidence of the Prince Charming Syndrome among female employees as a significant source of the gender gap in DC participation rates. Among corporate pension-covered employees, the gender difference in the efficacy of DC portability is a more significant gap-generating factor. DC tax advantage is particularly favored by pension-covered female employees over male counterparts, reducing the DC preference gap. No similar evidence is found for employees with no corporate pension coverage.

    Gap Resolution is a software package that was developed to improve Newbler genome assemblies by automating the closure of sequence gaps caused by repetitive regions in the DNA. This is done by performing the follow steps:1) Identify and distribute the data for each gap in sub-projects. 2) Assemble the data associated with each sub-project using a secondary assembler, such as Newbler or PGA. 3) Determine if any gaps are closed after reassembly, and either design fakes (consensus of closed gap) for those that closed or lab experiments for those that require additional data. The software requires as input a genome assembly produce by the Newbler assembler provided by Roche and 454 data containing paired-end reads.

    2016-01-01

    Full Text Available Newly diagnosed type 2 diabetes (T2 DM patients who do not receive diabetes education (DE have average knowledge on DM, and their practices about diabetes need to be improved. This prompted us to evaluate what happens when old diagnosed patients receive DE. The study therefore assessed the association between knowledge and practices in terms of Hemoglobin A1c (HbA1c, body mass index (BMI, and waist circumference (WC among 500 diagnosed T2 DM using a cross-sectional design. An interviewer-administered questionnaire was used for assessing their knowledge. The mean knowledge score of the patients was 15.29 ± 3.6. A significant negative association was found between the knowledge score and the HbA1c level. Age was positively associated with HbA1c and WC. Duration of DM was positively and education was negatively associated with HbA1c. Gender was negatively associated with BMI while income was positively associated with BMI and WC. All the associations were significant. The diagnosed T2 DM patients are deficient of sufficient knowledge; the knowledge score and HbA1c have a significant negative relationship, not other actions. The risk factors for the patients’ outcome include old age, female gender, years of education, economic status, and duration of DM.

    Knowledge translation is an essential and emerging arena in healthcare research. It is the process of aiding the application of research knowledge into clinical practice or policymaking. Individuals at all levels of the health care system, including patients, healthcare professionals, and policymakers, are affected by the gaps that exist between research evidence and practice; the process of knowledge translation plays a role in bridging these gaps and incorporating high-quality clinical research into decision-making. Cardiovascular disease (CVD) management is a crucial area of healthcare where information gaps are known to exist. Although Japan has one of the lowest risks and mortality rates from CVDs, an increasing trend of cardiovascular incidence and changes in the risk factor conditions have been observed in recent years. This article provides an overview of knowledge translation and its importance in the cardiovascular health of the Japanese population, and describes the key steps of a typical knowledge translation strategy.

  1. Tire Crumb Research Study Literature Review / Gap ...

    Science.gov (United States)

    In order to more fully understand data gaps in human exposure and toxicity to tire crumb materials, ATSDR, CPSC and EPA undertook a collaborative effort in the form of a scientific literature review and subsequent gaps analysis. The first objective of the Literature Review and Gap Analysis (LRGA) collaboration was to identify the existing body of literature related specifically to human exposure to tire crumb materials through the use of synthetic turf athletic fields and playgrounds. The second objective was to characterize and summarize the relevant data from the scientific literature. The final objective was to review the summary information and identify data gaps to build on the current understanding of the state-of-the-science and inform the development of specific research efforts that would be most impactful in the near-term. Because of the need for additional information, the U.S. Environmental Protection Agency (EPA), the Centers for Disease Control and Prevention/Agency for Toxic Substances and Disease Registry (ATSDR), and the U.S. Consumer Product Safety Commission (CPSC) launched a multi-agency action plan to study key environmental human health questions. The Federal Research Action Plan includes numerous activities, including research studies (U.S. EPA, 2016). A key objective of the Action Plan is to identify key knowledge gaps.

    Full Text Available Different kinds of omissions sometimes occur, or are perceived to occur, in traditional narratives and in tradition-inspired literature. A familiar instance is when a narrator realizes that he or she does not fully remember the story that he or she has begun to tell, and so leaves out part of it, which for listeners may possibly result in an unintelligible narrative. But many instances of narrative gap are not so obvious. From straightforward, objective gaps one can distinguish less-obvious subjective gaps: in many cases narrators do not leave out anything crucial or truly relevant from their exposition, and yet readers perceive gaps and take steps to fill them. The present paper considers four examples of subjective gaps drawn from ancient Greek literature (the Pandora myth, ancient Roman literature (the Pygmalion legend, ancient Hebrew literature (the Joseph legend, and early Christian literature (the Jesus legend. I consider the quite varied ways in which interpreters expand the inherited texts of these stories, such as by devising names, manufacturing motives, creating backstories, and in general filling in biographical ellipses. Finally, I suggest an explanation for the phenomenon of subjective gaps, arguing that, despite their variety, they have a single cause.

    Rest-frame UV, uniquely sensitive to luminous, short-lived hot massive stars, trace and age-date star formation across galaxies, and is very sensitive to dust, whose properties and presence are closely connected to star formation.With wide f-o-v and deep sensitivity in two broad filters,FUV and NUV,GALEX delivered the first comprehensive UV view of large nearby galaxies, and of the universe to z~2 (e.g.,Bianchi 2014 ApSS 354,103), detected star formation at the lowest rates, in environments where it was not seen before and not expected (e.g. Bianchi 2011 ApSS 335,51; Thilker+2009 Nature 457,990;2007 ApJS 173,538), triggering a new era of investigations with HST and large ground-based telescopes. New instrument technology and modeling capabilities make it now possible and compelling to solve standing issues. The scant UV filters available (esp. FUV) and the wide gap in resolution and f-o-v between GALEX and HST leaves old and new questions open. A chief limitation is degeneracies between physical parameters of stellar populations (age/SFR) and hot stars, and dust (e.g. Bianchi+ 2014 JASR 53,928).We show sample model simulations for filter optimization to provide critical measurements for the science objectives. We also demonstrate how adequate FUV+NUV filters, and resolution, allow us to move from speculative interpretation of UV data to unbiased physical characterization of young stellar populations and dust, using new data from UVIT, which, though smaller than CETUS, has better resolution and filter coverage than GALEX.Also, our understanding of galaxy chemical enrichment is limited by critical gaps in stellar evolution; GALEX surveys enabled the first unbiased census of the Milky Way hot-WD population (Bianchi+2011 MNRAS, 411,2770), which we complement with SDSS, Pan-STARRS, and Gaia data to fill such gaps (Bianchi et al.2018, ApSS). Such objects in CETUS fields (deeper exposures, more filters, and the first UV MOS) will be much better characterized, enabling

    Diabetes mellitus is becoming a serious public health problem in Sri Lanka and many other developing countries in the region. It is well known that effective management of diabetes reduces the incidence and progression of many diabetes related complications, thus it is important that General Practitioners (GPs) have sound knowledge and positive attitudes towards all aspects of its management. This study aims to assess knowledge, awareness and practices relating to management of Diabetes Mellitus among Sri Lankan GPs. A cross-sectional study was conducted among all 246 GPs registered with the Ceylon College of General Practitioners using a pre-validated self-administered questionnaire. 205 responded to the questionnaire(response rate 83.3%). Their mean duration of practice was 28.7 ± 11.2 years. On average, each GP had 27 ± 25 diabetic-patient consultations per-week. 96% managed diabetic patients and 24% invariably sought specialist opinion. 99.2% used blood glucose to diagnose diabetes but correct diagnostic cut-off values were known by only 48.8%. Appropriate use of HbA1c and urine microalbumin was known by 15.2% and 39.2% respectively. 84% used HbA1c to monitor glyceamic control, while 90.4% relied on fasting blood glucose to monitor glyceamic control. Knowledge on target control levels was poor.Nearly 90% correctly selected the oral hypoglyceamic treatment for obese as well as thin type 2 diabetic patients. Knowledge on the management of diabetes in pregnancy was poor. Only 23.2% knew the correct threshold for starting lipid-lowering therapy. The concept of strict glycaemic control in preference to symptom control was appreciated only by 68%. The skills for comprehensive care in subjects with multiple risk factors were unsatisfactory. The study was done among experienced members of the only professional college dedicated to the specialty. However, we found that there is room for improvement in their knowledge and practices related to diabetes. We recommend

    International activities with regards the development of methods for assessing impacts on the environment from ionising radiation have been substantial in recent years. In developing these methods, there are requirements (i) to determine the transfer of radionuclides within ecosystems and (ii) to determine background dose-rates arising from the presence of naturally occurring radionuclides, in a satisfactory manner. It has quickly become evident that fulfilling these 2 requirements is not entirely straightforward reflecting a lack of data in many cases. This report specifies exactly where these data-gaps lie through analyses of data generated from the most recent studies conducted internationally on this topic. It is evident that information is limited for numerous radionuclides from U-238 and Th-232 decay series and notably, in view of its importance as a contributor to dose-rates in plants and animals, Po-210. The simple way to rectify these data deficiencies is to organise target field campaigns focusing on particular species and radionuclides where information is lacking. To this end, field sampling has been conducted in a semi-natural mountain ecosystem in Norway and freshwater aquatic systems in Finland. It is envisaged that the data derived from the studies briefly described in this report will provide fundamental information for our understanding of the behaviour and fate of natural decay series radionuclides in terrestrial and aquatic systems and provide the basis for more robust way.

The co-production process engages regional/national stakeholders who form a Stakeholder Competency Group (from policy and practice), and, a Business Research Partnership Group comprising local business participants. The two groups have opportunities to liaise and network in discussing the prototype for the learning tool. Whatmore et al (2008) and McEwen et al (2014) show that stakeholder views, experience and expertise can strengthen research outputs. The approach reflects current ethics and practices of stakeholder participation in that alongside an academic approach to the research, other equally valid forms of knowledge are recognised: 'a lot can be learned from exploring parallels, controversies and frictions between different forms of competency and knowledge (McEwen et al, 2014), for example, scientific, local, tacit and embedded. This paper presents concerns identified by businesses and wider stakeholders in relation to how the tool is framed and its key design premises. The tool is planned as a living resource that can support a community of learning practice among SMEs to increase flood resilience in the face of increased risk.

  14. Overcoming the knowledge-behavior gap: The effect of evidence-based HPV vaccination leaflets on understanding, intention, and actual vaccination decision.

    2014-03-10

    Informed decision making requires transparent and evidence-based (=balanced) information on the potential benefit and harms of medical preventions. An analysis of German HPV vaccination leaflets revealed, however, that none met the standards of balanced risk communication. We surveyed a sample of 225 girl-parent pairs in a before-after design on the effects of balanced and unbalanced risk communication on participants' knowledge about cervical cancer and the HPV vaccination, their perceived risk, their intention to have the vaccine, and their actual vaccination decision. The balanced leaflet increased the number of participants who were correctly informed about cervical cancer and the HPV vaccine by 33 to 66 absolute percentage points. In contrast, the unbalanced leaflet decreased the number of participants who were correctly informed about these facts by 0 to 18 absolute percentage points. Whereas the actual uptake of the HPV vaccination 14 months after the initial study did not differ between the two groups (22% balanced leaflet vs. 23% unbalanced leaflet; p=.93, r=.01), the originally stated intention to have the vaccine reliably predicted the actual vaccination decision for the balanced leaflet group only (concordance between intention and actual uptake: 97% in the balanced leaflet group, rs=.92, p=.00; 60% in the unbalanced leaflet group, rs=.37, p=.08). In contrast to a unbalanced leaflet, a balanced leaflet increased people's knowledge of the HPV vaccination, improved perceived risk judgments, and led to an actual vaccination uptake, which first was robustly predicted by people's intention and second did not differ from the uptake in the unbalanced leaflet group. These findings suggest that balanced reporting about HPV vaccination increases informed decisions about whether to be vaccinated and does not undermine actual uptake. Copyright © 2014 The Authors.

    2005-01-01

    ELETRONUCLEAR, a state-owned company responsible for design, construction, ownership and operation of nuclear power plants in Brazil, is applying systematic measures to preserve its essential technological know-how. A special project called 'Determination of Technological Know-How of ELETRONUCLEAR' was established in January 2001 for this purpose. The extent and location of the existing know-how was identified and the gaps in the essential know-how were evaluated. A multidisciplinary team was established to implement the project. The team interacted with experts both in Brazil and abroad to achieve a sound technical basis as far as knowledge identification and preservation techniques are concerned. The results of this know-how survey were stored in an electronic data bank, which facilitated the creation of several types of reports, according to various criteria. An in-depth analysis of the survey pointed to the gaps in essential know-how. Proposals for solutions to fill in the know-how gaps were set up, comprising both short-term, as well as long-term, solutions. This project was the first work by ELETRONUCLEAR in the field of Knowledge Management. An indirect consequence was the creation of a nucleus of personnel competent in this new discipline, which had a multiplying effect throughout ELETRONUCLEAR, allowing the execution of other new projects in KM.

    The purpose of this document is to review the existing SRTC design against the ''Nuclear Safety Design Bases for License Application'' (NSDB) [Ref. 10] requirements and to identify codes and standards and supplemental requirements to meet these requirements. If these codes and standards and supplemental requirements can not fully meet these safety requirements then a ''gap'' is identified. These gaps will be identified here and addressed using the ''Site Rail Transfer Cart (SRTC) Design Development Plan'' [Ref. 14]. The codes and standards, supplemental requirements, and design development requirements are provided in the SRTC and associated rails gap analysis table in Appendix A. Because SRTCs are credited with performing functions important to safety (ITS) in the NSDB [Ref. 10], design basis requirements are applicable to ensure equipment is available and performs required safety functions when needed. The gap analysis table is used to identify design objectives and provide a means to satisfy safety requirements. To ensure that the SRTC and rail design perform required safety Functions and meet performance criteria, this portion of the gap analysis table supplies codes and standards sections and the supplemental requirements and identifies design development requirements, if needed

    A large gap exists between the completion of clinical research demonstrating the benefit of new treatment interventions and improved patient outcomes resulting from implementation of these interventions as part of routine clinical practice. This gap clearly affects patient safety and quality of care. Knowledge translation is important for addressing this gap, but evaluation of the most appropriate and effective knowledge translation methods is still ongoing. Through describing one model for knowledge translation and an example of its implementation, insights can be gained into systematic methods for advancing the implementation of evidence-based interventions to improve safety, quality, and patient outcomes.

  1. Filling the Knowledge Gap: Measuring HIV Prevalence and Risk Factors among Men Who Have Sex with Men and Female Sex Workers in Tripoli, Libya

    Background Publications on Libya’s HIV epidemic mostly examined the victims of the tragic nosocomial HIV outbreak in the 1990s and the related dispute about the detention of foreign medical workers. The dispute resolution in 2003 included an agreement with the European Union on humanitarian cooperation and the development of Libya’s first National HIV Strategy. As part of this we conducted Libya’s first bio-behavioural survey among men having sex with men (MSM) and female sex workers (FSW). Methods Using respondent-driven sampling, we conducted a cross-sectional study to estimate the prevalence of HIV, hepatitis B virus (HBV), hepatitis C virus (HCV), and related risk factors among 227 MSM and 69 FSW in Tripoli (FSW recruitment ended prematurely due to the political events in 2011). Results For MSM we estimated an HIV prevalence of 3.1%, HBV prevalence of 2.9%, and HCV prevalence of 7.3%, and for FSW an HIV prevalence of 15.7%, HBV prevalence of 0%, and HCV prevalence of 5.2%. We detected high levels of risk behaviours, poor HIV-related knowledge, high stigma and lack of prevention programmes. These results must be interpreted in the context of the political situation which prohibited reaching an ideal sample size for FSW. Conclusion There is urgent need to implement an effective National HIV Strategy informed by the results of this research. The risk of transmission within different risk groups and to the general population may be high given the recent military events that led to increased violence, migration, and the disruption of essential HIV-related services.

    There are few data describing patient-identified precipitants of heart failure (HF) hospitalization. We hypothesized a patient's perception of reason for or preventability of an admission may be related to 30-day readmission rates. Ninety-four patients admitted with decompensated HF from July 2014 to March 2015 completed a brief questionnaire regarding circumstances leading to admission. Thirty-day outcomes were assessed via telephone call and chart review. Mean age was 58 ± 14 years, with 60% blacks (n = 56) and 41% females (n = 39). Median left ventricular ejection fraction was 30%; 27 had preserved ejection fraction. Seventy-two patients identified their hospitalization to be due to HF (± another condition). Most common patient-identified precipitants of admission were worsening HF (n = 37) and dietary nonadherence (n = 11). Readmitted patients tended to have longer time until first follow-up appointment (21 vs 8 days). Seven of the 42 patients who identified their hospitalization as preventable were readmitted compared with 21/49 who believed their hospitalization was unpreventable (P = .012). On multivariate regression analysis, patients who thought their hospitalization was preventable were less likely to be readmitted (odds ratio 0.31; 95% confidence interval 0.10-0.91; P = .04). Almost 50% of patients believe their HF hospitalization is preventable, and these patients appear to be less likely to be readmitted within 30 days. Notably, patients cite nonadherence and lack of knowledge as reasons hospitalizations are preventable. These results lend insight into possible interventions to reduce HF readmissions.

    Treating patients requires the inclusion of existing evidence in any health care decision, to be able to choose the best diagnosis or treatment measure or to make valid prognosis statements for a particular patient in consideration of the physician's own expertise.The basis are clinical trials, the results of which are ideally gathered in systematic reviews, rated, summarized and published. In addition to the GCP (Good Clinical Practice)-compliant planning, conducting and analysis of clinical studies it is essential, that all study results are made publicly available, in order to avoid publication bias. This includes the public registration of planned and discontinued trials. In the last 25 years, the evidence-based medicine (EbM) has increasingly found its way into clinical practice and research. Here EbM is closely associated with the names Archibald Cochrane and David Sackett. In Germany, both the German Cochrane Centre (DCZ) and the network of evidence-based medicine (DNEbM) were established approximately 15 years ago. In the international Cochrane Collaboration clinicians and other scientists like statisticians interdisciplinary work side by side to develop the methods of evidence-based medicine and to address the topics of evidence generation and processing as well as the transfer of knowledge. Challenge: Existing evidence primarily serves doctors to support their decision-making, but is also the basis for providing scientific proof for a health care intervention's benefit to patients and ultimately payers/health insurances. The closure of existing evidence gaps requires substantial human and financial resources, a complex organizational structure and can only succeed with the involvement of clinical and methodological expertise and specific knowledge in the field of clinical research. In addition, the knowledge must be transferred into practice, using journals, guidelines, conferences, databases, information portals with processed evidence and not least the

  4. Aerosol-Cloud Interactions in the South-East Atlantic: Knowledge Gaps, Planned Observations to Address Them, and Implications for Global Climate Change Modeling

    Southern Africa produces almost a third of the Earth's biomass burning (BB) aerosol particles, yet the fate of these particles and their influence on regional and global climate is poorly understood. Particles lofted into the mid-troposphere are transported westward over the South-East (SE) Atlantic, home to one of the three permanent subtropical Stratocumulus (Sc) cloud decks in the world. The stratocumulus "climate radiators" are critical to the regional and global climate system. They interact with dense layers of BB aerosols that initially overlay the cloud deck, but later subside and are mixed into the clouds. These interactions include adjustments to aerosol-induced solar heating and microphysical effects. As emphasized in the latest IPCC report, the global representation of these aerosol-cloud interaction processes in climate models is one of the largest uncertainty in estimates of future climate. Hence, new observations over the SE Atlantic have significant implications for global climate change scenarios. We discuss the current knowledge of aerosol and cloud property distributions based on satellite observations and sparse suborbital sampling, and describe planned field campaigns in the region. Specifically, we describe the scientific objectives and implementation of the following four synergistic, international research activities aimed at providing a process-level understanding of aerosol-cloud interactions over the SE Atlantic: 1) ORACLES (Observations of Aerosols above Clouds and their interactions), a five-year investigation between 2015 and 2019 with three Intensive Observation Periods (IOP), recently funded by the NASA Earth-Venture Suborbital Program, 2) CLARIFY-2016 (Cloud-Aerosol-Radiation Interactions and Forcing: Year 2016), a comprehensive observational and modeling programme funded by the UK's Natural Environment Research Council (NERC), and supported by the UK Met Office. 3) LASIC (Layered Atlantic Smoke Interactions with Clouds), a funded

    The impetus for evidence-based practice (EBP) has grown out of widespread concern with the quality, effectiveness (including cost-effectiveness), and efficiency of medical care received by the public. Although initially focused on medicine, EBP principles have been adopted by many of the health care professions and are often represented in practice through the development and use of clinical practice guidelines (CPGs). Audiology has been working on incorporating EBP principles into its mandate for professional practice since the mid-1990s. Despite widespread efforts to implement EBP and guidelines into audiology practice, gaps still exist between the best evidence based on research and what is being done in clinical practice. A collaborative dynamic and iterative integrated knowledge translation (KT) framework rather than a researcher-driven hierarchical approach to EBP and the development of CPGs has been shown to reduce the knowledge-to-clinical action gaps. This article provides a brief overview of EBP and CPGs, including a discussion of the barriers to implementing CPGs into clinical practice. It then offers a discussion of how an integrated KT process combined with a community of practice (CoP) might facilitate the development and dissemination of evidence for clinical audiology practice. Finally, a project that uses the knowledge-to-action (KTA) framework for the development of outcome measures in pediatric audiology is introduced. PMID:22194314

    Full Text Available Theme – It is know that the large public and auditors hold different beliefs about the auditors’ duties and responsibilities. In this conditions audit expectation gap represents that level of expectation that remains uncovered. In this study paper, audit expectation gap represents the difference between the achievements of public auditors and the expectations that general public (students have beyond those responsibility. Purpose – The evolution of audit expectation gap has been examined in various countries, but the extent of the concept has not been investigated so much in public area. This study attempts to assess the perceptions of possible future auditors, students, regarding the existence of expectation gap in public area. Literature review – A review of the literature identifies many researches who define the concept since was given the first definition of audit expectation gap as the difference between the levels of expected performance and the results that auditors give, but just a few analysis the public area using students’ knowledge to understand the perception of future users of accounting information or potential bidders of accounting information. Methodology – This paper represents the beginning of a broader study that will be part of the doctoral thesis entitled “Organization and exercise of public audit in Romania”, started in 2009 at University Babes Bolyai from Cluj Napoca, coordinated by PhD Professor Matis Dumitru. The aim of this paper is to explore the findings of an empirical study, made on 352 students, were the primary data used were obtained through a questionnaire technique regarding the audit expectation gap in the public sector in Romania, looking into future to obtain responses using a larger respondent group. Findings – A reasonableness gap was uncovered, there is a gap between the expectation of students regarding the public auditors' profession and their results and there are differences

    The use of array comparative genomic hybridization (aCGH) has been increasingly widespread. The challenge of integration of this technology into prenatal diagnosis was the interpretation of results and communicating findings of unclear clinical significance. This study assesses the knowledge and acceptance of prenatal aCGH in Hong Kong obstetricians and pregnant women. The aim is to identify the needs and gaps before implementing the replacement of karyotyping with aCGH. Questionnaires with aCGH information in the form of pamphlets were sent by post to obstetrics and gynecology doctors. For the pregnant women group, a video presentation, pamphlets on aCGH and a self-administered questionnaire were provided at the antenatal clinic. The perception of aCGH between doctors and pregnant women was similar. Doctors not choosing aCGH were more concerned about the difficulty in counseling of variants of unknown significance and adult-onset disease in pregnant women, whereas pregnant women not choosing aCGH were more concerned about the increased waiting time leading to increased anxiety. Prenatal aCGH is perceived as a better test by both doctors and patients. Counseling support, training, and better understanding and communication of findings of unclear clinical significance are necessary to improve doctor-patient experience.

    Previous research [S. J. Pollock , Phys. Rev. ST Phys. Educ. Res. 3, 1 (2007)] showed that despite the use of interactive engagement techniques, the gap in performance between males and females on a conceptual learning survey persisted from pretest to post-test at the University of Colorado at Boulder. Such findings were counter to previously published work [M. Lorenzo , Am. J. Phys. 74, 118 (2006)]. This study begins by identifying a variety of other gender differences. There is a small but significant difference in the course grades of males and females. Males and females have significantly different prior understandings of physics and mathematics. Females are less likely to take high school physics than males, although they are equally likely to take high school calculus. Males and females also differ in their incoming attitudes and beliefs about physics. This collection of background factors is analyzed to determine the extent to which each factor correlates with performance on a conceptual post-test and with gender. Binned by quintiles, we observe that males and females with similar pretest scores do not have significantly different post-test scores (p>0.2) . The post-test data are then modeled using two regression models (multiple regression and logistic regression) to estimate the gender gap in post-test scores after controlling for these important prior factors. These prior factors account for about 70% of the observed gender gap. The results indicate that the gender gap exists in interactive physics classes at our institution but is largely associated with differences in previous physics and math knowledge and incoming attitudes and beliefs.

    Science.gov (United States)

    Dreier, Gabriele; Löhler, Jan

    2016-01-01

    Background: Medical treatment requires the implementation of existing evidence in the decision making process in order to be able to find the best possible diagnostic, therapeutic or prognostic measure for the individual patient based on the physician's own expertise. Clinical trials form the evidence base and ideally, their results are assembled, analyzed, summarized, and made available in systematic review articles. Beside planning, conducting, and evaluating clinical trials in conformity with GCP (good clinical practice), it is essential that all results of conducted studies are publicly available in order to avoid publication bias. This includes also the public registration of planned and cancelled trials. History: During the last 25 years, evidence-based medicine became increasingly important in medical care and research. It is closely associated with the names of Archibald Cochrane and David Sackett. About 15 years ago, the Deutsche Cochrane Zentrum (Cochrane Germany) and the Deutsche Netzwerk Evidenzbasierte Medizin e.V. (German Network for Evidence-based Medicine, DNEbM) were founded in Germany. In the International Cochrane Collaboration, clinicians and methodologists come together on an interdisciplinary level to further develop methods of evidence-based medicine and to discuss the topics of evidence generation and processing as well as knowledge transfer. Problem: Evidence is particularly important for physicians in the process of decision making, however, at the same time it is the base of a scientific proof of benefit for the patient and finally for the payers in health care. The closure of evidence gaps requires enormously high staff and financial resources, significant organizational efforts, and it is only successful when clinical and methodical expertise as well as specific knowledge in the field of clinical research are included. On the other hand, the knowledge has to be transferred into practice. For this purpose, practice guidelines, meetings

  20. Does Glocal Political Power Already Exist?

    Directory of Open Access Journals (Sweden)

    Lorenzo Ornaghi

    2017-05-01

    Full Text Available Large periods of history are usually characterized by equally important moments of change in scientific knowledge and, in particular, in the understanding of political power. We still need to study in depth whether the former provokes (almost of out necessity the latter, or whether they are “great” because they are favored by the innovation of the paradigms of knowledge. The passage from medieval universalism to the particularism of the modern age represents an extremely interesting analogy when compared to the transformations that are now underway. The example of John of Salisbury’s Policratus, the starting point of this article, is illuminating in our comprehension of the relevance of the interweaving between the persistence of the ancient forms of recognition of power and the search for new forms. The existence of glocal realities is already a fact. Even if it is relatively easy to recognize these realities (a business, a university, a humanitarian association, not a few of the same “parts” which constitute the traditional organization of the State, it is more difficult to define the specific characteristics of the power at their disposal. Moving from the widening gap between “actual” power and “potential” power, the article examines the motives for which the classical definitions of power are always becoming more insufficient in understanding the role now emerging from glocal realities. And, in particular, by looking at how the “command-obedience” relationship is changing also as a consequence of communication networks and information technology, the article analyzes that specific “contamination” within global elements and local elements, which seems to be the main base of glocal political power.

    2018-06-01

    The current review attempts to demonstrate the value of several forms of carbon dioxide (CO2) gaps in resuscitation of the critically ill patient as monitor for the adequacy of the circulation, as target for fluid resuscitation and also as predictor for outcome. Fluid resuscitation is one of the key treatments in many intensive care patients. It remains a challenge in daily practice as both a shortage and an overload in intravascular volume are potentially harmful. Many different approaches have been developed for use as target of fluid resuscitation. CO2 gaps can be used as surrogate for the adequacy of cardiac output (CO) and as marker for tissue perfusion and are therefore a potential target for resuscitation. CO2 gaps are easily measured via point-of-care analysers. We shed light on its potential use as nowadays it is not widely used in clinical practice despite its potential. Many studies were conducted on partial CO2 pressure differences or CO2 content (cCO2) differences either alone, or in combination with other markers for outcome or resuscitation adequacy. Furthermore, some studies deal with CO2 gap to O2 gap ratios as target for goal-directed fluid therapy or as marker for outcome. CO2 gap is a sensitive marker of tissue hypoperfusion, with added value over traditional markers of tissue hypoxia in situations in which an oxygen diffusion barrier exists such as in tissue oedema and impaired microcirculation. Venous-to-arterial cCO2 or partial pressure gaps can be used to evaluate whether attempts to increase CO should be made. Considering the potential of the several forms of CO2 measurements and its ease of use via point-of-care analysers, it is recommendable to implement CO2 gaps in standard clinical practice.

    Nuclear knowledge is characterized by high-complexity and variety of the component topics and long duration required by the build-up of individual competence. At organizational level, these characteristics made the power of an organization or institution to be determined by the capital accumulated of existing knowledge. Furthermore, the capacity of an organization to re-generate and raise the knowledge capital according to the specific processes it is running according to the existing demand decides its position/ranking in the economy of nuclear field. Knowledge management emphasizes re-utilization of existing practice and experience, upgrade, enrich and re-value of accumulated knowledge. The present paper identifies and classifies the nuclear knowledge steps, namely: tacit knowledge, explicit knowledge, preserving, transfer, knowledge capture etc. On this basis there are identified the existing problems of nuclear knowledge management in Romania such as: difficulties to keep within the country the existing expertise, lack of interest in nuclear education, low level of organization of existing knowledge due to a small number of data bases, an insufficient integration of existing knowledge in IT systems, lack of ontology and taxonomy or an average structuralism. Nuclear knowledge in Romania is facing a major challenge which is generated by the future development of nuclear facilities. It is related to the rising demand of expertise and experts. This challenge is better solved by partnership between end users and institutions of Research and Development and university organization as well which could ensure the generation, transfer and preservation of nuclear knowledge.

    Full Text Available Abstract Background Levels of knowledge about diabetes mellitus (DM among newly diagnosed diabetics in Bangladesh are unknown. This study assessed the relationship between knowledge and practices among newly diagnosed type 2 DM patients. Methods Newly diagnosed adults with type 2 diabetes (N = 508 were selected from 19 healthcare centers. Patients’ knowledge and self-care practices were assessed via interviewer-administered questionnaires using a cross-sectional design. Knowledge questions were divided into basic and technical sections. Knowledge scores were categorized as poor (mean + 1 SD. Chi square testing and multivariate logistic regression were conducted to examine the relationship between diabetes-related knowledge and self-care practices. Results Approximately 16%, 66%, and 18% of respondents had good, average, and poor (GAP basic knowledge respectively and 10%, 78%, and 12% of respondents had GAP technical knowledge, about DM. About 90% of respondents from both basic and technical GAP did not test their blood glucose regularly; a significant relationship existed between basic knowledge and glucose monitoring. Technical knowledge and foot care were significantly related, though 81% with good technical knowledge and about 70% from average and poor groups did not take care of their feet. Approximately 85%, 71%, and 52% of the GAP technical knowledge groups, consumed betel nuts; a significant relationship existed between technical knowledge and consumption of betel nuts. Around 88%, 92%, and 98% of GAP technical knowledge groups failed to follow dietary advice from a diabetes educator. About 26%, 42%, and 51% of GAP basic and technical sometimes ate meals at a fixed time (p Conclusions Newly diagnosed type 2 diabetics had similar levels of basic and technical knowledge of DM. Health education and motivation should create positive changes in diabetes-control-related self-care practices.

  18. A resuscitation "dilemma" theory-practice-ethics. Is there a theory-practice-ethics gap?

    Science.gov (United States)

    Mortell, Manfred

    2009-07-01

    The theory-practice-ethics gap - a new paradigm to contemplate. Practices based on tradition, rituals and outdated information are placed into a nonscientific paradigm called the theory-practice gap. Within this paradigm there is often a gap between theoretical knowledge and its application in practice. This theory-practice gap has always existed [Allmark, P., 1995. A classical view of the theory-practice gap in nursing. J. Adv. Nurs. 22 (1), 18-23; Hewison, A. et al., 1996. The theory-practice gap in nursing: a new dimension. J. Adv. Nurs. 24 (4), 754-761]. Its creation is often sited as a culmination of theory being idealistic and impractical, even if practical and beneficial, are often ignored. Most of the evidence relating to the non integration of theory and practice makes the assumption that environmental factors are responsible and will affect learning and practice outcomes, hence the "gap". In fact, it is the author's belief, that to "bridge the gap" between theory and practice an additional component is required, called ethics. A moral duty and obligation ensuring theory and practice integrate. In order to effectively implement new practices, one must deem these practices are worthy and relevant to their role as healthcare providers. Otherwise, we fall victims to providing nothing more than a lip service. This introduces a new concept which the author refers to as the theory-practice-ethics gap. This theory-practice-ethics gap must be considered when reviewing some of the unacceptable outcomes in health care practice. The author believes that there is a crisis of ethics where theory and practice integrate, and as a consequence, malfeasance. We are failing to fulfill our duty as healthcare providers and as patient advocates. One practice of major concern, which the author will endeavor to unfold relates to adult and pediatric resuscitation.

    In 2006, the Argentine Nuclear Regulatory Authority has initiated a regulatory knowledge management process to face the loss of knowledge resulting from retiring experts, the generation gap, and the existing need to train new human resources. A number of projects have been started together with the technical assistance of the National Public Administration Institute to preserve knowledge and render it explicit for the coming generations. These projects include 'The History of the Expert's Learning Process' in which the majority of the most critical experts have been interviewed so far. The results of this project help envision a training structure and prospective projects. An Internet Site has also been created on the Intranet in order to render knowledge explicit and facilitate the tools for knowledge management initiatives. Furthermore, ARN's knowledge map project has also been started. (author) [es

  1. Business knowledge in surgeons.

    Satiani, Bhagwan

    2004-07-01

    Surgeons and residents in training receive little, if any, formal education in the economic side of clinical practice during medical school or residency. As medical professionals face shrinking reimbursement, loss of control over health care decisions, and limited resources, surgical specialties must reevaluate the need to teach their members business survival skills. Before designing business related-teaching modules, educators must know the exact gaps in knowledge that exist among surgeons. This article reports a survey of 133 surgeons in the Midwest who were asked to rate their knowledge base in 11 business topics relevant to the practice of medicine. The survey showed that the average surgeon perceives himself or herself to be poorly equipped to understand basic financial accounting principles, financial markets, economics of health care, tools for evaluating purchases, marketing, budgets, antitrust and fraud and abuse regulations, and risk and return on investments. Armed with this data, teaching faculty, health care systems, and medical specialty societies should design business education seminars to better position surgical specialists and trainees to communicate with insurers, hospital administrators, health care organizations, and their own personal financial advisors.

    Much of our current knowledge about the physiological and pathophysiological role of gap junctions is based on experiments where coupling has been reduced by either chemical agents or genetic modification. This has brought evidence that gap junctions are important in many physiological processes.......

    Echeburúa, Enrique

    2012-01-01

    Hypersexual Disorder has been proposed as a new psychiatric disorder for DSM-V, characterized by an increased frequency and intensity of sexually motivated fantasies, arousal, urges, and enacted behavior in association with an impulsivity component. Excessive appetitive and consummatory behaviors, including hypersexuality, can become a non-chemical addiction. Sexual addiction afflicts people having paraphilic or nonparaphilic behaviors associated with progressive risk-taking sexual behaviors, escalation or progression of sexual behaviors (tolerance), loss of control and significant adverse psychosocial consequences, such as unplanned pregnancy, pair-bond dysfunction, marital separation, financial problems and sexually transmitted diseases including HIV. The most common behaviors involved in sexual addiction are fantasy sex, compulsive masturbation, pornography, cybersex, voyeuristic sex, anonymous sex and multiple sexual partners. These behaviors are intended to reduce anxiety and other dysphoric affects (e.g., shame and depression). Axis I psychiatric diagnosis, especially mood disorders, psychoactive substance abuse disorders and attention deficit hyperactivity disorders, are common comorbid disorders with sexual addiction. There are significant gaps in the current scientific knowledge base regarding the clinical course, development risk factors and family history and data on women with sexual addiction are lacking.

    The researches of periodic structures have a long history with the main contents confined in the field of forward problem. In this paper, the inverse problem is considered and an overall frame is proposed which includes two main stages, i.e., the band gap criterion and its optimization. As a preliminary investigation, the inverse problem of the flexural vibrational band gap of a periodically supported beam is analyzed. According to existing knowledge of its forward problem, the band gap criterion is given in implicit form. Then, two cases with three independent parameters, namely the double supported case and the triple one, are studied in detail and the explicit expressions of the feasible domain are constructed by numerical fitting. Finally, the parameter optimization of the double supported case with three variables is conducted using genetic algorithm aiming for the best mean attenuation within specified frequency band.

  13. Why preeclampsia still exists?

    2013-08-01

    Preeclampsia (PE) is a deadly gestational disease affecting up to 10% of women and specific of the human species. Preeclampsia is clearly multifactorial, but the existence of a genetic basis for this disease is now clearly established by the existence of familial cases, epidemiological studies and known predisposing gene polymorphisms. PE is very common despite the fact that Darwinian pressure should have rapidly eliminated or strongly minimized the frequency of predisposing alleles. Consecutive pregnancies with the same partner decrease the risk and severity of PE. Here, we show that, due to this peculiar feature, preeclampsia predisposing-alleles can be differentially maintained according to the familial structure. Thus, we suggest that an optimal frequency of PE-predisposing alleles in human populations can be achieved as a result of a trade-off between benefits of exogamy, importance for maintaining genetic diversity and increase of the fitness owing to a stable paternal investment.

    For the production of biogas by co-fermentation, manure is mixed with organic waste products that can be fermented, such as harvesting residues and food remains. Since biogas possesses both flammable and toxic properties, large-scale production systems are always associated with potential safety risks. Biogas is a mixture of gases and has flammable properties due to the presence of methane (CH4). It is less well known that biogas also has toxic properties when it contains high levels of hydrogen sulfide (H2S). In a previous study, the RIVM recommended that standards pertaining to the minimum safety level be applied for the construction and operation of biogas production plants. A subsequent study by the RIVM concluded that the guideline 'Handreiking (co-)vergisting van mest' ('Manual co-fermentation of manure') provides a basic framework to achieve this recommended minimum safety level. The RIVM therefore recommends that this latter document be used and further supplemented with specific information for inspection and licensing authorities, the main users of this document. The composition of the biogas determines whether or not a specific installation falls within or outside the scope of certain (safety) legislation and, consequently, which specific safety regulations and safety inspections are mandatory. As a clear, consistent and predictable composition of biogas does not exist, stricter monitoring of biogas composition in the different compartments of the production plant is recommended. The current assessment of potential safety risks associated with the production of biogas is that these risks principally relate to those working at the biogas installation and are much less relevant to local residents. Further investigations are needed to determine if this is indeed the case [Dutch] Voor de productie van biogas door co-vergisting wordt mest vermengd met restanten van bijvoorbeeld oogsten of voedsel die kunnen vergisten.

    Bioethicists disagree over methods, theories, decision-making guides, case analyses and public policies. Thirty years ago, the thinking of many scholars coalesced around a principlist approach to bioethics. That mid-level mode of moral reasoning is now one of many approaches to moral deliberation. Significant variation in contemporary approaches to the study of ethical issues related to medicine, biotechnology and health care raises the question of whether bioethics exists as widely shared method, theory, normative framework or mode of moral reasoning.

    If a constructibly countable ordinal alpha is a gap ordinal, then the order type of the set of index ordinals smaller than alpha is exactly alpha. The gap ordinals are the only points of discontinuity of a certain ordinal-valued function. The notion of gap minimality for well ordered systems of notations is defined, and the existence of gap-minimal systems of notations of arbitrarily large constructibly countable length is established.

    Knowledge of the spectrum of energies for beta, gamma, and neutron radiation experienced in the field is crucial to the proper interpretation of personnel dose. Calibration sources and techniques are determined on the basis of their relationship to field exposure. Selected techniques were used to obtain neutron, photon, and beta energy spectra data at several Hanford locations. Four neutron energy spectra and dose measurement methods were used: (1) multisphere spectrometer system; (2) tissue equivalent proportional counter (TEPC); (3) RASCAL (9'' to 3'' sphere ratios); and (4) helium-3 neutron spectrometer. Gamma spectroscopy was done using standard techniques. A specially designed TLD dosimeter was used to obtain beta spectrum measurements. The design and use of each of these instruments is described in the body of this report. Data collected and analyzed for each of the Hanford locations are included

    Unbunched beam is a potentially serious issue in the LHC as it may quench the superconducting magnets during a beam abort. Unbunched particles, either not captured by the RF system at injection or leaking out of the RF bucket, will be removed by using the existing damper kickers to excite resonantly the particles in the abort gap. Following beam simulations, a strategy for cleaning the abort gap at different energies was proposed. The plans for the commissioning of the beam abort gap cleaning are described and first results from the beam commissioning are presented.

    2016-03-01

    In this paper, we outline the relationship between the need to put existing applied health research knowledge into practice (the 'know-do gap') and the need to improve the evidence base (the 'know gap') with respect to the healthcare process used for older people with frailty known as comprehensive geriatric assessment (CGA). We explore the reasons for the know-do gap and the principles of how these barriers to implementation might be overcome. We explore how these principles should affect the conduct of applied health research to close the know gap. We propose that impaired flow of knowledge is an important contributory factor in the failure to implement evidence-based practice in CGA; this could be addressed through specific knowledge mobilisation techniques. We describe that implementation failures are also produced by an inadequate evidence base that requires the co-production of research, addressing not only effectiveness but also the feasibility and acceptability of new services, the educational needs of practitioners, the organisational requirements of services, and the contribution made by policy. Only by tackling these issues in concert and appropriate proportion, will the know and know-do gaps for CGA be closed. © The Author 2016.

    Full Text Available It is well known that the notion of measure and integral were released early enough in close connection with practical problems of measuring of geometric figures. Notion of measure was outlined in the early 20th century through H. Lebesgue’s research, founder of the modern theory of measure and integral. It was developed concurrently a technique of integration of functions. Gradually it was formed a specific area todaycalled the measure and integral theory. Essential contributions to building this theory was made by a large number of mathematicians: C. Carathodory, J. Radon, O. Nikodym, S. Bochner, J. Pettis, P. Halmos and many others. In the following we present several abstract sets, classes of sets. There exists the sets which are not Lebesgue measurable and the sets which are Lebesgue measurable but are not Borel measurable. Hence B ⊂ L ⊂ P(X.

    2009-12-01

    Supergiant Fast X-ray Transients (SFXTs) are one of the most interesting (and unexpected) results of the INTEGRAL mission. They are a new class of HMXBs displaying short hard X-ray outbursts (duration less tha a day) characterized by fast flares (few hours timescale) and large dinamic range (10E3-10E4). The physical mechanism driving their peculiar behaviour is still unclear and highly debated: some models involve the structure of the supergiant companion donor wind (likely clumpy, in a spherical or non spherical geometry) and the orbital properties (wide separation with eccentric or circular orbit), while others involve the properties of the neutron star compact object and invoke very low magnetic field values (B 1E14 G, magnetars). The picture is still highly unclear from the observational point of view as well: no cyclotron lines have been detected in the spectra, thus the strength of the neutron star magnetic field is unknown. Orbital periods have been measured in only 4 systems, spanning from 3.3 days to 165 days. Even the duty cycle seems to be quite different from source to source. The Energetic X-ray Imaging Survey Telescope (EXIST), with its hard X-ray all-sky survey and large improved limiting sensitivity, will allow us to get a clearer picture of SFXTs. A complete census of their number is essential to enlarge the sample. A long term and continuous as possible X-ray monitoring is crucial to -(1) obtain the duty cycle, -(2 )investigate their unknown orbital properties (separation, orbital period, eccentricity),- (3) to completely cover the whole outburst activity, (4)-to search for cyclotron lines in the high energy spectra. EXIST observations will provide crucial informations to test the different models and shed light on the peculiar behaviour of SFXTs.

    2016-01-01

    Nutritional issues among older adults with cancer are an understudied area of research despite significant prognostic implications for treatment side effects, cancer-specific mortality, and overall survival. In May of 2015, the National Cancer Institute and the National Institute on Aging co-sponsored a conference focused on future directions in geriatric oncology research. Nutritional research among older adults with cancer was highlighted as a major area of concern as most nutritional cancer research has been conducted among younger adults, with limited evidence to guide the care of nutritional issues among older adults with cancer. Cancer diagnoses among older adults are increasing, and the care of the older adult with cancer is complicated due to multimorbidity, heterogeneous functional status, polypharmacy, deficits in cognitive and mental health, and several other non-cancer factors. Due to this complexity, nutritional needs are dynamic, multifaceted, and dependent on the clinical scenario. This manuscript outlines the proceedings of this conference including knowledge gaps and recommendations for future nutritional research among older adults with cancer. Three common clinical scenarios encountered by oncologists include (1) weight loss during anti-cancer therapy, (2) malnutrition during advanced disease, and (3) obesity during survivorship. In this manuscript, we provide a brief overview of relevant cancer literature within these three areas, knowledge gaps that exist, and recommendations for future research. PMID:27197919

    2010-07-01

    One manifestation of globalization is medical tourism. As its implications remain largely unknown, we reviewed claimed benefits and risks. Driven by high health-care costs, long waiting periods, or lack of access to new therapies in developed countries, most medical tourists (largely from the United States, Canada, and Western Europe) seek care in Asia and Latin America. Although individual patient risks may be offset by credentialing and sophistication in (some) destination country facilities, lack of benefits to poorer citizens in developing countries offering medical tourism remains a generic equity issue. Data collection, measures, and studies of medical tourism all need to be greatly improved if countries are to assess better both the magnitude and potential health implications of this trade.

    2017-02-01

    fluctuations in LW load over time intervals greater than a few years. Other knowledge gaps relate to physical and ecological effects of wood, including the magnitude of flow resistance caused by LW; patterns of wood-related sediment storage for diverse river sizes and channel geometry; quantification of channel-floodplain-LW interactions; and potential threshold effects of LW in relation to physical processes and biotic communities. Finally, knowledge gaps are related to management of large wood and river corridors, including understanding the consequences of enormous historical reductions in LW load in rivers through the forested portions of the temperate zone; and how to effectively reintroduce and manage existing LW in river corridors, which includes enhancing public understanding of the importance of LW. Addressing these knowledge gaps requires more case studies from diverse rivers, as well as more syntheses and metadata analyses.

  3. On the existence of hot positronium reactions

    International Nuclear Information System (INIS)

    Lazzarini, E.

    1984-01-01

    The existence of hot Ps reactions is nowadays questioned; the controversy arises from the two models (the Ore gap and the spur theories) advanced in order to explain the mechanism of the positronium formation and of its inhibition in liquids by dissolution of certain compounds. The hypothesis of the hot Ps reactions was initially advanced as an additional statement for explaining the inhibition phenomenon within the framework of the Ore gap theory, but it is not considered necessary for the spur theory. The present paper is chiefly intended as a presentation of this particular aspect of Ps chemistry to hot atom chemists unspecialized in the field. The reader is assumed to be familiar with the basic physics and experimental methods used in positronium chemistry. Contents: positrons and positronium formation; inhibition and enhancement of Ps formation in solutions; positronium reactions in gases. (Auth.)

    2006-01-01

    Chalcopyrites, in particular those with a wide band gap, are fascinating materials in terms of their technological potential in the next generation of thin-film solar cells and in terms of their basic material properties. They exhibit uniquely low defect formation energies, leading to unusual doping and phase behavior and to extremely benign grain boundaries. This book collects articles on a number of those basic material properties of wide-gap chalcopyrites, comparing them to their low-gap cousins. They explore the doping of the materials, the electronic structure and the transport through interfaces and grain boundaries, the formation of the electric field in a solar cell, the mechanisms and suppression of recombination, the role of inhomogeneities, and the technological role of wide-gap chalcopyrites.

  12. Sustainability Tools Inventory - Initial Gaps Analysis | Science ...

    Science.gov (United States)

    This report identifies a suite of tools that address a comprehensive set of community sustainability concerns. The objective is to discover whether "gaps" exist in the tool suite’s analytic capabilities. These tools address activities that significantly influence resource consumption, waste generation, and hazard generation including air pollution and greenhouse gases. In addition, the tools have been evaluated using four screening criteria: relevance to community decision making, tools in an appropriate developmental stage, tools that may be transferrable to situations useful for communities, and tools with requiring skill levels appropriate to communities. This document provides an initial gap analysis in the area of community sustainability decision support tools. It provides a reference to communities for existing decision support tools, and a set of gaps for those wishing to develop additional needed tools to help communities to achieve sustainability. It contributes to SHC 1.61.4

  14. Spatio-temporal gap analysis of OBIS-SEAMAP project data: assessment and way forward.

    Directory of Open Access Journals (Sweden)

    Connie Y Kot

    Full Text Available The OBIS-SEAMAP project has acquired and served high-quality marine mammal, seabird, and sea turtle data to the public since its inception in 2002. As data accumulated, spatial and temporal biases resulted and a comprehensive gap analysis was needed in order to assess coverage to direct data acquisition for the OBIS-SEAMAP project and for taxa researchers should true gaps in knowledge exist. All datasets published on OBIS-SEAMAP up to February 2009 were summarized spatially and temporally. Seabirds comprised the greatest number of records, compared to the other two taxa, and most records were from shipboard surveys, compared to the other three platforms. Many of the point observations and polyline tracklines were located in northern and central Atlantic and the northeastern and central-eastern Pacific. The Southern Hemisphere generally had the lowest representation of data, with the least number of records in the southern Atlantic and western Pacific regions. Temporally, records of observations for all taxa were the lowest in fall although the number of animals sighted was lowest in the winter. Oceanographic coverage of observations varied by platform for each taxa, which showed that using two or more platforms represented habitat ranges better than using only one alone. Accessible and published datasets not already incorporated do exist within spatial and temporal gaps identified. Other related open-source data portals also contain data that fill gaps, emphasizing the importance of dedicated data exchange. Temporal and spatial gaps were mostly a result of data acquisition effort, development of regional partnerships and collaborations, and ease of field data collection. Future directions should include fostering partnerships with researchers in the Southern Hemisphere while targeting datasets containing species with limited representation. These results can facilitate prioritizing datasets needed to be represented and for planning research for

  15. Hand hygiene compliance: is there a theory-practice-ethics gap?

    Science.gov (United States)

    Mortell, Manfred

    Practice is usually based on tradition, rituals and outdated information; there is often an additional gap between theoretical knowledge and its application in practice. This theory-practice gap has long existed (Allmark, 1995; Hewison et al, 1996). It often arises when theory is ignored because it is seen as idealistic and impractical, even if it is practical and beneficial. Most research relating to the lack of integration between theory and practice has concluded that environmental factors are responsible and will affect learning and practice outcomes. The author believes an additional dimension of ethics is required to bridge the gap between theory and practice. This would be a moral obligation to ensure theory and practice are integrated. To implement new practices effectively, healthcare practitioners must deem these practices worthwhile and relevant to their role. This introduces a new concept that the author calls the theory-practice-ethics gap. This theory-practice-ethics gap must be considered when examining some of the unacceptable outcomes in healthcare practice (Mortell, 2009). The literature suggests that there is a crisis of ethics where theory and practice integrate, and practitioners are failing to fulfil their duty as providers of healthcare and as patient advocates. This article examines the theory-practice-ethics gap when applied to hand hygiene. Non-compliance exists in hand hygiene among practitioners, which may increase patient mortality and morbidity rates, and raise healthcare costs. Infection prevention and control programmes to improve hand hygiene among staff include: ongoing education and training; easy access to facilities such as wash basins; antiseptic/alcohol handgels that are convenient, effective, and skin- and user-friendly; and organisational recognition and support for clinicians in hand washing and handgel practices. Yet these all appear to have failed to achieve the required and desired compliance in hand hygiene.

    In this paper, we introduce uncertainty of the labour productivity of women in a competitive model of wage determination. We demonstrate that more qualified women are then offered much lower wages than men at the equilibrium. This result is consistent with the glass ceiling hypothesis according to which there exist larger gender wage gaps at the upper tail of the wage distribution.

  20. Managing Uncertainty in Water Infrastructure Design Using Info-gap Robustness

    Science.gov (United States)

    Irias, X.; Cicala, D.

    2013-12-01

    Info-gap theory, a tool for managing deep uncertainty, can be of tremendous value for design of water systems in areas of high seismic risk. Maintaining reliable water service in those areas is subject to significant uncertainties including uncertainty of seismic loading, unknown seismic performance of infrastructure, uncertain costs of innovative seismic-resistant construction, unknown costs to repair seismic damage, unknown societal impacts from downtime, and more. Practically every major earthquake that strikes a population center reveals additional knowledge gaps. In situations of such deep uncertainty, info-gap can offer advantages over traditional approaches, whether deterministic approaches that use empirical safety factors to address the uncertainties involved, or probabilistic methods that attempt to characterize various stochastic properties and target a compromise between cost and reliability. The reason is that in situations of deep uncertainty, it may not be clear what safety factor would be reasonable, or even if any safety factor is sufficient to address the uncertainties, and we may lack data to characterize the situation probabilistically. Info-gap is a tool that recognizes up front that our best projection of the future may be wrong. Thus, rather than seeking a solution that is optimal for that projection, info-gap seeks a solution that works reasonably well for all plausible conditions. In other words, info-gap seeks solutions that are robust in the face of uncertainty. Info-gap has been used successfully across a wide range of disciplines including climate change science, project management, and structural design. EBMUD is currently using info-gap to help it gain insight into possible solutions for providing reliable water service to an island community within its service area. The island, containing about 75,000 customers, is particularly vulnerable to water supply disruption from earthquakes, since it has negligible water storage and is

    This paper examines the financing structure of small and medium-sized enterprises (SMEs) in Germany and questions whether an equity gap - or, more generally, a financing gap -exists. Reviewing the literature and available data sources, we find that financing constraints seem to affect, if at all, only a very small subgroup among highly growth-oriented firms. We do not detect any structural problems in average SME's capital structure. Rather, German Mittelstand firms appear to be non-growth or...

    2015-08-01

    Full Text Available Authentication factors refer to user login credentials that a user supplies to an authentication process for it to decide whether to grant or deny access. While two-factor and three-factor authentication generally provides better security than one-factor authentication the aim of this paper is to review security in individual authentication factor credentials that are in use nowadays. These credentials will be discussed in factor categories knowledge factor possession factor and inherence factor. The paper details current security gaps and some novel approaches to diminish the gaps in these authentication factors. We believe that our recommendations will inspire development of better authentication credentials and systems.

We propose that, like aging itself, the longevity gender gap is exceedingly complex and argue that it may arise from sex-related hormonal differences and from somatic cell selection that favors cells more...... resistant to the ravages of time. We discuss the interplay of these factors with telomere biology and oxidative stress and suggest that an explanation for the longevity gender gap may arise from a better understanding of the differences in telomere dynamics between men and women....

    2012-06-01

    Full Text Available In the review, peculiarities of spectra of one-dimensional photonic crystals made of anisotropic and/or magnetooptic materials are considered. The attention is focused on band gaps of a special type—the so called degenerate band gaps which are degenerate with respect to polarization. Mechanisms of formation and properties of these band gaps are analyzed. Peculiarities of spectra of photonic crystals that arise due to the linkage between band gaps are discussed. Particularly, it is shown that formation of a frozen mode is caused by linkage between Brillouin and degenerate band gaps. Also, existence of the optical Borrmann effect at the boundaries of degenerate band gaps and optical Tamm states at the frequencies of degenerate band gaps are analyzed.

  10. Uncertainty, probability and information-gaps

    International Nuclear Information System (INIS)

    Ben-Haim, Yakov

    2004-01-01

    This paper discusses two main ideas. First, we focus on info-gap uncertainty, as distinct from probability. Info-gap theory is especially suited for modelling and managing uncertainty in system models: we invest all our knowledge in formulating the best possible model; this leaves the modeller with very faulty and fragmentary information about the variation of reality around that optimal model. Second, we examine the interdependence between uncertainty modelling and decision-making. Good uncertainty modelling requires contact with the end-use, namely, with the decision-making application of the uncertainty model. The most important avenue of uncertainty-propagation is from initial data- and model-uncertainties into uncertainty in the decision-domain. Two questions arise. Is the decision robust to the initial uncertainties? Is the decision prone to opportune windfall success? We apply info-gap robustness and opportunity functions to the analysis of representation and propagation of uncertainty in several of the Sandia Challenge Problems

    1988-10-01

    By considering the electron interaction in polyacetylene, it is found that two gap states in charged solitons of trans-polyacetylene exist: one is deep level, another is shallow level. The deep one shifts 0.23 ev down (for positive soliton) or up (for negative soliton) from the center of the gap; while the shallow one is 0.06 ev under the bottom of conduction band (positive soliton) or above the top of valence band (negative soliton). These results agree with the absorption spectra of trans-polyacetylene. (author). 5 refs, 4 figs

    Knowledge management has become an important concept in the nuclear industry globally. This has been driven by the fact that new reactors are commissioned and some are decommissioned. Since most old experts are near retirement then there is a need to capture the nuclear knowledge and expertise and transfer it to the new generation. Knowledge transfer is one of the important building blocks of knowledge management. Processes and strategies need to be developed in order to transfer this knowledge. South African Young Nuclear Professionals Society (SAYNPS) has established a document to address strategies that can be used to close the knowledge gap between the young less experienced and experts in the field. This action will help the young generation to participate in knowledge management. The major challenges will be the willingness of the experts to share and making sure that all knowledge is captured, stored and kept up to date. The paper presents the SAYNPS point of view with regard to knowledge transfer. (authors)

    2013-10-15

    Narrow gap electronegative (EN) capacitive discharges are widely used in industry and have unique features not found in conventional discharges. In this paper, plasma parameters are determined over a range of decreasing gap length L from values for which an electropositive (EP) edge exists (2-region case) to smaller L-values for which the EN region connects directly to the sheath (1-region case). Parametric studies are performed at applied voltage V{sub rf}=500 V for pressures of 10, 25, 50, and 100 mTorr, and additionally at 50 mTorr for 1000 and 2000 V. Numerical results are given for a parallel plate oxygen discharge using a planar 1D3v (1 spatial dimension, 3 velocity components) particle-in-cell (PIC) code. New interesting phenomena are found for the case in which an EP edge does not exist. This 1-region case has not previously been investigated in detail, either numerically or analytically. In particular, attachment in the sheaths is important, and the central electron density n{sub e0} is depressed below the density n{sub esh} at the sheath edge. The sheath oscillations also extend into the EN core, creating an edge region lying within the sheath and not characterized by the standard diffusion in an EN plasma. An analytical model is developed using minimal inputs from the PIC results, and compared to the PIC results for a base case at V{sub rf}=500 V and 50 mTorr, showing good agreement. Selected comparisons are made at the other voltages and pressures. A self-consistent model is also developed and compared to the PIC results, giving reasonable agreement.

  1. Explaining the black-white gap in cognitive test scores: Toward a theory of adverse impact.

    Science.gov (United States)

    Cottrell, Jonathan M; Newman, Daniel A; Roisman, Glenn I

    2015-11-01

    In understanding the causes of adverse impact, a key parameter is the Black-White difference in cognitive test scores. To advance theory on why Black-White cognitive ability/knowledge test score gaps exist, and on how these gaps develop over time, the current article proposes an inductive explanatory model derived from past empirical findings. According to this theoretical model, Black-White group mean differences in cognitive test scores arise from the following racially disparate conditions: family income, maternal education, maternal verbal ability/knowledge, learning materials in the home, parenting factors (maternal sensitivity, maternal warmth and acceptance, and safe physical environment), child birth order, and child birth weight. Results from a 5-wave longitudinal growth model estimated on children in the NICHD Study of Early Child Care and Youth Development from ages 4 through 15 years show significant Black-White cognitive test score gaps throughout early development that did not grow significantly over time (i.e., significant intercept differences, but not slope differences). Importantly, the racially disparate conditions listed above can account for the relation between race and cognitive test scores. We propose a parsimonious 3-Step Model that explains how cognitive test score gaps arise, in which race relates to maternal disadvantage, which in turn relates to parenting factors, which in turn relate to cognitive test scores. This model and results offer to fill a need for theory on the etiology of the Black-White ethnic group gap in cognitive test scores, and attempt to address a missing link in the theory of adverse impact.

  2. Treefall Gap Mapping Using Sentinel-2 Images

    2017-11-01

    Full Text Available Proper knowledge about resources in forest management is fundamental. One of the most important parameters of forests is their size or spatial extension. By determining the area of treefall gaps inside the compartments, a more accurate yield can be calculated and the scheduling of forestry operations could be planned better. Several field- and remote sensing-based approaches are in use for mapping but they provide only static measurements at high cost. The Earth Observation satellite mission Sentinel-2 was put in orbit as part of the Copernicus programme. With the 10-m resolution bands, it is possible to observe small-scale forestry operations like treefall gaps. The spatial extension of these gaps is often less than 200 m2, thus their detection can only be done on sub-pixel level. Due to the higher temporal resolution of Sentinel-2, multiple observations are available in a year; therefore, a time series evaluation is possible. The modelling of illumination can increase the accuracy of classification in mountainous areas. The method was tested on three deciduous forest sites in the Börzsöny Mountains in Hungary. The area evaluation produced less than 10% overestimation with the best possible solutions on the sites. The presented work shows a low-cost method for mapping treefall gaps which delivers annual information about the gap area in a deciduous forest.

    Santero, Nicholas; Masanet, Eric; Horvath, Arpad

    2010-04-20

    This report provides a critical review of existing literature and modeling tools related to life-cycle assessment (LCA) applied to pavements. The review finds that pavement LCA is an expanding but still limited research topic in the literature, and that the existing body of work exhibits methodological deficiencies and incompatibilities that serve as barriers to the widespread utilization of LCA by pavement engineers and policy makers. This review identifies five key issues in the current body of work: inconsistent functional units, improper system boundaries, imbalanced data for asphalt and cement, use of limited inventory and impact assessment categories, and poor overall utility. This review also identifies common data and modeling gaps in pavement LCAs that should be addressed in future work. These gaps include: the use phase (rolling resistance, albedo, carbonation, lighting, leachate, and tire wear and emissions), asphalt fumes, feedstock energy of bitumen, traffic delay, the maintenance phase, and the end-of-life phase. This review concludes with a comprehensive list of recommendations for future research, which shed light on where improvements in knowledge can be made that will benefit the accuracy and comprehensiveness of pavement LCAs moving forward.

    Ketler, S K

    2000-06-01

    This article compares the social settings and teaching organization of two differently structured childbirth education courses in Cagliari, Italy, in order to understand how social processes and contexts work to negotiate authoritative knowledge. Although the explicit goal of both courses was to transmit biomedical knowledge, knowledge based in women's experience nonetheless dominated some course sessions. Thus, I examine the social processes and interactions that enabled women's experiential knowledge to dominate discussions and subsequently share in the authority of biomedical knowledge in some situations. Because few existing studies do so, this article also addresses a gap in our current understanding by exploring not only how experiential knowledge comes to share authority with biomedical knowledge, but also, why it is important that it does. Focusing on the efficacy of differently structured courses, this article informs the planning of future childbirth education courses in similar settings.

    The problem of fish going through turbines at hydroelectric power plants and the growing concern over the survival rate of salmon at the US Army Corps operated Bonneville lock and dam on the Columbia river in the Pacific Northwest is discussed. The protection of the fish, the assessment of the hazards facing fish passing through turbines, the development of a new turbine, and improved turbine efficiency that reduces cavitation, turbulence and shear flow are examined. The closing of the gap between the turbine blades, hub and discharge ring to increase efficiency and reduce the risk to fish, and the development of the minimum gap runner (MGR) are described, and the lower maximum permitted power output of MGR is noted.

    Conclusion: The nurses had adequate general knowledge about the principles of acute pain assessment in CIAP. However, some knowledge gaps exist about key concepts in pain assessment and these can curtail the efforts to ensure quality pain assessment and management in CIAP. The findings entrench the need for focused professional training and continuing professional education about best practices for pain assessment and management in CIAP.

    Summary Objective Decisions made during electronic health record (EHR) implementations profoundly affect usability and safety. This study aims to identify gaps between the current literature and key stakeholders’ perceptions of usability and safety practices and the challenges encountered during the implementation of EHRs. Materials and Methods Two approaches were used: a literature review and interviews with key stakeholders. We performed a systematic review of the literature to identify usability and safety challenges and best practices during implementation. A total of 55 articles were reviewed through searches of PubMed, Web of Science and Scopus. We used a qualitative approach to identify key stakeholders’ perceptions; semi-structured interviews were conducted with a diverse set of health IT stakeholders to understand their current practices and challenges related to usability during implementation. We used a grounded theory approach: data were coded, sorted, and emerging themes were identified. Conclusions from both sources of data were compared to identify areas of misalignment. Results We identified six emerging themes from the literature and stakeholder interviews: cost and resources, risk assessment, governance and consensus building, customization, clinical work-flow and usability testing, and training. Across these themes, there were misalignments between the literature and stakeholder perspectives, indicating major gaps. Discussion Major gaps identified from each of six emerging themes are discussed as critical areas for future research, opportunities for new stakeholder initiatives, and opportunities to better disseminate resources to improve the implementation of EHRs. Conclusion Our analysis identified practices and challenges across six different emerging themes, illustrated important gaps, and results suggest critical areas for future research and dissemination to improve EHR implementation.

    A megavolt gas-filled trigatron gap with a sectional gas-discharge chamber having a more than three-fold range of operating voltages is described. The discharge chamber consists of ten sections, each 70 mm thick, made of organic glass. The sections are separated one from another by aluminium gradient rings to which ohmic voltage divider is connected. Insulational sections and gradient rings are braced between themselves by means of metal flanges through gaskets made of oil-resistant rubber with the help of fiberglass-laminate pins. The gap has two electrodes 110 mm in diameter. The trigatron ignition assembly uses a dielectric bushing projecting over the main electrode plane. Use has been made of a gas mixture containing 10% of SF 6 and 90% of air making possible to ensure stable gap operation without readjusting in the voltage range from 0.4 to 1.35 MV. The operation time lag in this range is equal to 10 μs at a spread of [ru

  15. Advances, gaps, and future prospects in biological soil crust research

    Research progress has led to the understanding that biological soil crusts (biocrusts) are often complete miniature ecosystems comprising a variety of photosynthesizers (cyanobacteria, algae, lichens, bryophytes), decomposers like bacteria, fungi, and archaea, and heterotrophic organisms, like protozoa, nematodes, and microarthropods feeding on them. Biocrusts are one of the oldest terrestrial ecosystems, playing central roles in the structure and functioning of dryland ecosystems and presumably also influencing global biogeochemical cycles. On the other hand, biocrusts have been shown to be highly sensitive to global change, being easily destroyed by mechanical disturbance and severely threatened by minor changes in climate patterns. Despite the large increase in biocrust research, we still see major knowledge gaps which need to be tackled. Considering biodiversity studies, there are major regions of potential biocrust occurrence, where hardly any studies have been conducted. Molecular identification techniques are increasingly employed, but genetically characterized entities need to be linked with morphologically identified organisms to identify their ecological roles. Although there is a large body of research on the role of biocrusts in water and nutrient budgets, we are still far from closing the overall cycles. Results suggest that not all mechanisms have been identified, yet, leading to sometimes contradictory results between different studies. Knowledge on how to minimize impact to biocrusts during surface-disturbing activities has hardly been gained, and despite research efforts, instructions on effective biocrust restoration are still exemplary. In order to fill these research gaps, novel scientific approaches are needed. We expect that global research networks could be extremely helpful to answer scientific questions by tackling them within different regions, utilizing the same methodological techniques. Global networks could also be used for long

  16. The gap of views on radioactive waste issues

    Full text: There are few issues in our society causing more concern among the general public - for several reasons - than the radioactive waste. There are also few areas where the gap between the laymen views on risks differ more from the objective scientific views of the involved expertise. After many years of R and D there exist technologies to take care of today's waste products and also solid knowledge for the long term solutions; the big problem of today is therefore - will society make use of it? Can we bridge the gap in views between experts and the layman to facilitate necessary political support and decisions for the radioactive waste issues? The paper deals with the political, social and opinion-forming aspects of the decision process and its elements and relation to the scientific and technical issues. For the building of a deep repository it is not at all enough to satisfy scientific and technical requirements. Today it is in particular obvious that we need a drastically much better process to handle the political, social and opinion-forming aspects. Without this we will not get the necessary support to bring ongoing programmes for long term solutions forward. The communication process must be drastically more understandable and better address peoples concerns. Todays knowledge allow for simplifications and structuring of problems. Perspectives can and must be given not only on traditional factors as risks over time, the large safety margins, rather in what way waste can be a problem for an individual human and the importance of the circumstances. Most aspects are debated in connection with the siting of a repository. The on-going Swedish programme aiming to build a first phase of a deep repository illustrate several of siting aspects in a general way. The last five years experience from the Swedish programme and its interaction with many groups in the society like municipalities are discussed. (author)

    Purpose - The purpose of the paper is to amend shortcomings of existing theory concerning organizational learning and knowledge management. Design/methodology/approach – The paper reviews and refines existing theory. Findings - Findings from cognitive neuroscience suggest that technical knowledge...... domains essential for product development are largely nonlinguistic. Operations management/strategy tools enable the use of tacit knowledge in its tacit form and discourage premature standardization. Similarly, language use introduces standardization, which if introduced prematurely, causes incrementalism...... in line with findings from product development research. However, frameworks on organizational learning and knowledge management focus on language development and neglect use of tacit knowledge and the benefits involved with allowing elements of new product ideas to mature in a tacit form. Originality...

    The current study attempted to investigate the development of Arabic academic vocabulary knowledge among middle-school Arabic native speakers, taking into account the socioeconomic status of the Arab population in Israel. For this purpose, Arabic academic word list was developed, mapping the required academic words that are needed for adequate coping with informational texts as appearing in the different content areas text-books. Six-hundred Arabic speaking middle school pupils from the different areas in Israel, representing the different Arab subgroups: general Arab community, Druze and Bedouins, have participated in the current study. Two academic vocabulary tests, including receptive and productive academic vocabulary evaluation tests, were administrated to the students across the different age groups (7th, 8th and 9th). The results pointed to no significant difference between 7th and 9th grade in academic vocabulary knowledge. In contrast, significant difference was encountered between the different Arab sub-groups where the lowest scores were noted among the Bedouin sub-group, characterized by the lowest SES. When comparing receptive and productive academic vocabulary knowledge between 7th and 9th grade, the results pointed to improvement in receptive academic knowledge towards the end of middle school but not on the productive knowledge level. In addition, within participants' comparison indicated a gap between the pupils' receptive and productive vocabulary. The results are discussed in relation to the existing scientific literature and to its implication of both research and practice in the domain of Arabic literacy development.

    The purpose of this document is to review the existing the trunnion collar removal machine against the ''Nuclear Safety Design Bases for License Application'' (NSDB) [Ref. 10] requirements and to identify codes and standards and supplemental requirements to meet these requirements. If these codes and standards can not fully meet these requirements then a ''gap'' is identified. These gaps will be identified here and addressed using the ''Trunnion Collar Removal Machine Design Development Plan'' [Ref. 15]. The codes and standards, supplemental requirements, and design development requirements for the trunnion collar removal machine are provided in the gap analysis table (Appendix A, Table 1). Because the trunnion collar removal machine is credited with performing functions important to safety (ITS) in the NSDB [Ref. 10], design basis requirements are applicable to ensure equipment is available and performs required safety functions when needed. The gap analysis table is used to identify design objectives and provide a means to satisfy safety requirements. To ensure that the trunnion collar removal machine performs required safety functions and meets performance criteria, this portion of the gap analysis tables supplies codes and standards sections and the supplemental requirements and identifies design development requirements, if needed
