    Based on the ecological and economic problems in Good Agriculture Practice (GAP) of Chinese material medica, we introduced the origin, concept, features and operative technology of eco-agriculture worldwide, emphasizing its modes on different biological levels of landscape, ecosystem, community, population, individual and gene in China. And on this basis, we analyzed the background and current situation of eco-agriculture of Chinese materia medica, and proposed its development ideas and key tasks, including: (1) Analysis and planning of the production pattern of Chinese material medica national wide. (2) Typical features extraction of regional agriculture of Chinese materia medica. (3) Investigation of the interaction and its mechanism between typical Chinese materia medica in each region and the micro-ecology of rhizosphere soil. (4) Study on technology of eco-agriculture of Chinese materia medica. (5) Extraction and solidification of eco-agriculture modes of Chinese materia medica. (6) Study on the theory of eco-agriculture of Chinese materia medica. Also we pointed out that GAP and eco-agriculture of Chinese material medica are both different and relative, but they are not contradictory with their own features. It is an irresistible trend to promote eco-agriculture in the GAP of Chinese material medica and coordinate ecological and economic development.

    The implementation of good agricultural practices (GAP) from irrigation water to the tomato packaging process enhances the safety of fresh produce and its value throughout the food chain. The aim of the present study was to show that fresh produce farms that apply and enforce GAP could reduce the presence of Salmonella in finished produce. Samples were collected biweekly from six packing houses from the central region of Sinaloa, México, for the isolation of Salmonella spp by the ISO 6579:2002 method, and the isolated strains were serotyped and genotyped by the Kauffmman-White scheme and pulsed field gel electrophoresis (PFGE), respectively. Salmonella strains were detected in 13 (36.1 %) irrigation water samples, while only two tomato samples were positive (5.5 %). Eight different serotypes were identified in irrigation water, and Salmonella Oranienburg (34 %) was the most prevalent; however, only Salmonella Agona and Salmonella Weltevreden were present on tomatoes. Salmonella Oranienburg was the most widely dispersed and variable serotype, with 10 different PFGE profiles. Salmonella Weltevreden was isolated from both types of samples, albeit with distinct genetic profiles, implying that the sources of contamination differ. These results confirm the utility of implementing good agricultural practices to reduce Salmonella contamination in irrigation water and the packaging process.

  4. Japanese consumer preferences for milk certified with the good agricultural practice(GAP) label.

    2013-01-01

    This study examined Japanese consumers' valuation of a good agricultural practice (GAP) label on packaged milk and investigated the effect of detailed GAP information on valuation. A total of 624 Japanese consumers were asked to select their most preferred milk through an online survey. The milk was assumed to have three attributes: the GAP label, Hazard Analysis and Critical Control Points certification, and price. The results showed that consumers' valuation of GAP was significantly positive. Although providing additional GAP information to a respondent who was aware of GAP and what it means had a positive effect on the consumers' valuation of GAP, provision of this information had no effect if the respondent knew about GAP either moderately or slightly, and had a negative effect if the respondent did not know about GAP at all. To increase broad consumer awareness and valuation of GAP, it is important to provide GAP information according to the requirements of consumers.

    This paper aims to summarize the achievements during the implementation process of good agricultural practice (GAP) in Chinese Materia Medica (CMM), and on basis of analyzing the existing problems of GAP, to propose further implementation of GAP in TCM growing. Since the launch of GAP in CMM growing ten years ago, it has acquired great achievements, including: (1) The promulgation of a series of measures for the administration of the GAP approval in the CMM growing; (2) The expanded planting area of CMM; (3) The increased awareness of standardized CMM growing among farmers and enterprises; (4) The establishment of GAP implementation bases for CMM growing; (5) The improvement of theory and methodology for CMM growing; (6) The development of a large group of experts and scholars in GAP approval for CMM production. The problems existing in the production include: (1) A deep understanding of GAP and its certification is still needed; (2) The distribution of the certification base is not reasonable; (3) The geo-economics effect and the backward farming practices are thought to be the bottlenecks in the standardization of CMM growing and the scale production of CMM; (4) Low comparative effectiveness limits the development of the GAP; (5) The base of breeding improved variety is blank; (6) The immature of the cultivation technique lead to the risk of production process; (7) The degradation of soil microbial and the continuous cropping obstacle restrict the sustainable development of the GAP base. To further promote the health and orderly GAP in the CMM growing, the authors propose: (1) To change the mode of production; (2) To establish a sound standard system so as to ensure quality products for fair prices; (3) To fully consider the geo-economic culture and vigorously promote the definite cultivating of traditional Chinese medicinal materials; (4) To strengthen the transformation and generalization of basic researches and achievements, in order to provide technical

    Eutrophication of fresh, transitional and coastal waters by excessive nutrient inputs is one of the most widespread water quality problems in developed countries. Sources of nutrient nitrogen (N) and phosphorus (P) can come from a multiplicity of sources and be dependent on numerous hydrological controls from catchments with both urban and agricultural landuses. Aquatic impacts are widely reported as a result of excessive nutrient transfers from land to water and include changes in ecological integrity and loss of amenity. In the European Union, the Water Framework Directive (WFD) and associated Directives are the key structures with which member states must develop national and often trans-national polices to deal with issues of water resources management. The linked Nitrates Directive is particularly concerned with integrating sustainable agriculture and good water quality objectives and is written into national polices. In Ireland this policy is the Nitrates Directive National Action Programme (NAP), Statutory Instruction 378, Good Agricultural Practise regulation, and amongst other things, sets targets and limits on the use of organic and inorganic fertilisers, soil fertility and slurry/fertiliser spreading and cultivation times. To evaluate the effectiveness of this policy, Teagasc, the Irish Agriculture and Food Development Authority, is undertaking a catchment scale audit on sources, sinks, and changes in nutrient use and export over several years. The Agricultural Catchments Programme is based on a science-stakeholder-management partnership to generate knowledge and specifically to protect water quality from nitrogen and phosphorus transfers within the constraints of the requirements of modern Irish agricultural practises. Eight catchments of 5-12 km2 have been selected for the programme to represent a range of agricultural intensities and vulnerabilities to nitrogen and phosphorus loss including catchments that are situated on permeable and impermeable

    Good Clinical Practice (GCP) is an international standard for the design, conduct, performance, monitoring, auditing, recording, analyses, and reporting of clinical trials. The goal of GCP is to ensure the protection of the rights, integrity, and confidentiality of clinical trial participants and to ensure the credibility and accuracy of data and reported results. In the United States, trial sponsors generally require investigators to complete GCP training prior to participating in each clinical trial to foster GCP and as a method to meet regulatory expectations (ie, sponsor’s responsibility to select qualified investigators per 21 CFR 312.50 and 312.53(a) for drugs and biologics and 21 CFR 812.40 and 812.43(a) for medical devices). This training requirement is often extended to investigative site staff, as deemed relevant by the sponsor, institution, or investigator. Those who participate in multiple clinical trials are often required by sponsors to complete repeated GCP training, which is unnecessarily burdensome. The Clinical Trials Transformation Initiative convened a multidisciplinary project team involving partners from academia, industry, other researchers and research staff, and government to develop recommendations for streamlining current GCP training practices. Recommendations drafted by the project team, including the minimum key training elements, frequency, format, and evidence of training completion, were presented to a broad group of experts to foster discussion of the current issues and to seek consensus on proposed solutions.

  2. Good Practices in Free-energy Calculations

    Pohorille, Andrew; Jarzynski, Christopher; Chipot, Christopher

    2013-01-01

    As access to computational resources continues to increase, free-energy calculations have emerged as a powerful tool that can play a predictive role in drug design. Yet, in a number of instances, the reliability of these calculations can be improved significantly if a number of precepts, or good practices are followed. For the most part, the theory upon which these good practices rely has been known for many years, but often overlooked, or simply ignored. In other cases, the theoretical developments are too recent for their potential to be fully grasped and merged into popular platforms for the computation of free-energy differences. The current best practices for carrying out free-energy calculations will be reviewed demonstrating that, at little to no additional cost, free-energy estimates could be markedly improved and bounded by meaningful error estimates. In energy perturbation and nonequilibrium work methods, monitoring the probability distributions that underlie the transformation between the states of interest, performing the calculation bidirectionally, stratifying the reaction pathway and choosing the most appropriate paradigms and algorithms for transforming between states offer significant gains in both accuracy and precision. In thermodynamic integration and probability distribution (histogramming) methods, properly designed adaptive techniques yield nearly uniform sampling of the relevant degrees of freedom and, by doing so, could markedly improve efficiency and accuracy of free energy calculations without incurring any additional computational expense.

  3. Good practices for quantitative bias analysis.

    2014-12-01

    Quantitative bias analysis serves several objectives in epidemiological research. First, it provides a quantitative estimate of the direction, magnitude and uncertainty arising from systematic errors. Second, the acts of identifying sources of systematic error, writing down models to quantify them, assigning values to the bias parameters and interpreting the results combat the human tendency towards overconfidence in research results, syntheses and critiques and the inferences that rest upon them. Finally, by suggesting aspects that dominate uncertainty in a particular research result or topic area, bias analysis can guide efficient allocation of sparse research resources. The fundamental methods of bias analyses have been known for decades, and there have been calls for more widespread use for nearly as long. There was a time when some believed that bias analyses were rarely undertaken because the methods were not widely known and because automated computing tools were not readily available to implement the methods. These shortcomings have been largely resolved. We must, therefore, contemplate other barriers to implementation. One possibility is that practitioners avoid the analyses because they lack confidence in the practice of bias analysis. The purpose of this paper is therefore to describe what we view as good practices for applying quantitative bias analysis to epidemiological data, directed towards those familiar with the methods. We focus on answering questions often posed to those of us who advocate incorporation of bias analysis methods into teaching and research. These include the following. When is bias analysis practical and productive? How does one select the biases that ought to be addressed? How does one select a method to model biases? How does one assign values to the parameters of a bias model? How does one present and interpret a bias analysis?. We hope that our guide to good practices for conducting and presenting bias analyses will encourage

    This paper explains how the pipeline industry can avoid violating the Clean Water Act (PL 92-500, Federal Water Pollution Control Act), which states that pollution of US waters from any cause other than an act of God, war or Government negligence is the responsibility of the owner or operator of the facility. Reporting pollution to the National Response Center will limit the maximum penalty to $5,000 Rectifiers must be kept in top operating condition, and visual inspections of the right-of-way by aerial or ground patrols must detect construction of new pipelines or other facilities. Accidental damage by third parties is the major cause of failures in pipeline systems, which can be prevented by periodic contact with landowners. Conclusion is that if a pipeline operator follows good operating and maintenance practices, his exposure to effects of the Clean Water Act will be minimal.

    A set of Good Clinical Laboratory Practice (GCLP) standards that embraces both the research and clinical aspects of GLP were developed utilizing a variety of collected regulatory and guidance material. We describe eleven core elements that constitute the GCLP standards with the objective of filling a gap for laboratory guidance, based on IND sponsor requirements, for conducting laboratory testing using specimens from human clinical trials. These GCLP standards provide guidance on implementing GLP requirements that are critical for laboratory operations, such as performance of protocol-mandated safety assays, peripheral blood mononuclear cell processing and immunological or endpoint assays from biological interventions on IND-registered clinical trials. The expectation is that compliance with the GCLP standards, monitored annually by external audits, will allow research and development laboratories to maintain data integrity and to provide immunogenicity, safety, and product efficacy data that is repeatable, reliable, auditable and that can be easily reconstructed in a research setting.

  12. Defense programs beryllium good practice guide

    SciTech Connect

    Herr, M.

    1997-07-01

    Within the DOE, it has recently become apparent that some contractor employees who have worked (or are currently working) with and around beryllium have developed chronic beryllium disease (CBD), an occupational granulomatous lung disorder. Respiratory exposure to aerosolized beryllium, in susceptible individuals, causes an immunological reaction that can result in granulomatous scarring of the lung parenchyma, shortness of breath, cough, fatigue, weight loss, and, ultimately, respiratory failure. Beryllium disease was originally identified in the 1940s, largely in the fluorescent light industry. In 1950, the Atomic Energy Commission (AEC) introduced strict exposure standards that generally curtailed both the acute and chronic forms of the disease. Beginning in 1984, with the identification of a CBD case in a DOE contractor worker, there was increased scrutiny of both industrial hygiene practices and individuals in this workforce. To date, over 100 additional cases of beryllium-specific sensitization and/or CBD have been identified. Thus, a disease previously thought to be largely eliminated by the adoption of permissible exposure standards 45 years ago is still a health risk in certain workforces. This good practice guide forms the basis of an acceptable program for controlling workplace exposure to beryllium. It provides (1) Guidance for minimizing worker exposure to beryllium in Defense Programs facilities during all phases of beryllium-related work, including the decontamination and decommissioning (D&D) of facilities. (2) Recommended controls to be applied to the handling of metallic beryllium and beryllium alloys, beryllium oxide, and other beryllium compounds. (3) Recommendations for medical monitoring and surveillance of workers exposed (or potentially exposed) to beryllium, based on the best current understanding of beryllium disease and medical diagnostic tests available. (4) Site-specific safety procedures for all processes of beryllium that is likely to

  7. Good Manufacturing Practices (GMP) / Good Laboratory Practices (GLP) Review and Applicability for Chemical Security Enhancements

    SciTech Connect

    Iveson, Steven W.

    2014-11-01

    Global chemical security has been enhanced through the determined use and integration of both voluntary and legislated standards. Many popular standards contain components that specifically detail requirements for the security of materials, facilities and other vital assets. In this document we examine the roll of quality management standards and how they affect the security culture within the institutions that adopt these standards in order to conduct business within the international market place. Good manufacturing practices and good laboratory practices are two of a number of quality management systems that have been adopted as law in many nations. These standards are designed to protect the quality of drugs, medicines, foods and analytical test results in order to provide the world-wide consumer with safe and affective products for consumption. These standards provide no established security protocols and yet manage to increase the security of chemicals, materials, facilities and the supply chain via the effective and complete control over the manufacturing, the global supply chains and testing processes. We discuss the means through which these systems enhance security and how nations can further improve these systems with additional regulations that deal specifically with security in the realm of these management systems. We conclude with a discussion of new technologies that may cause disruption within the industries covered by these standards and how these issues might be addressed in order to maintain or increase the level of security within the industries and nations that have adopted these standards.

    PubMed

    Hatchett, Lena; Brown, Loretta; Hopkins, Joan; Larsen, Kelly; Fournier, Eliza

    2015-01-01

    Food security is a challenge facing many African-American low-income communities nationally. Community and university partners have established urban agriculture programs to improve access to high quality affordable fruits and vegetables by growing, distributing, and selling food in urban neighborhoods. While the challenge of food security is within communities of color, few studies have described these urban agriculture programs and documented their impact on the crew members who work in the programs and live in the low-income communities. More information is needed on the program impact for crew and community health promotion. Using a survey and focus group discussion from the crew and staff we describe the program and activities of four Chicago Urban Agriculture programs. We summarized the impact these programs have on crew members' perception of urban agriculture, health habits, community engagement, and community health promotion in low-income African-American neighborhoods.

  14. Measures of the Effects of Agricultural Practices on Ecosystem Services

    SciTech Connect

    Dale, Virginia H; Polasky, Stephen

    2007-01-01

    Agriculture produces more than just crops. Agricultural practices have environmental impacts that affect a wide range of ecosystem services, including water quality, pollination, nutrient cycling, soil retention, carbon sequestration, and biodiversity conservation. In turn, ecosystem services affect agricultural productivity. Understanding the contribution of various agricultural practices to the range of ecosystem services would help inform choices about the most beneficial agricultural practices. To accomplish this, however, we must overcome a big challenge in measuring the impact of alternative agricultural practices on ecosystem services and of ecosystem services on agricultural production.

  15. [Blood components and good practices in transfusion].

    PubMed

    Andreu, Georges

    2015-02-01

    Each year, more than three millions of blood components are transfused to more than five hundred thousand patients in France. The optimal use of blood components requires that physicians prescribing blood components master the clinical indications of red blood cells concentrates, platelet concentrates and fresh frozen plasma. In addition, physicians in charge of blood component prescription should provide adequate pre- and post-transfusion information to their patients. Compliance of blood components administration in patients with safety guidelines contributes as well to their optimal use. In addition, for each blood component transfused, a proper evaluation of its safety and its efficacy should be done. Finally, a regular evaluation of transfusion practice in hospital services were blood components are used, through audits made in cooperation with their blood component provider, either blood transfusion centre or the hospital blood bank, enables to appreciate the level of compliance with safety and clinical guidelines, and more globally how the transfusion process is mastered.

  16. [Good practice of image-guided radiotherapy].

    PubMed

    de Crevoisier, R; Créhange, G; Castelli, J; Lafond, C; Delpon, G

    2015-10-01

    Image-guided radiotherapy (IGRT) aims to take into account the anatomical variations occurring during the course of radiotherapy, by direct or indirect visualization of the target volume followed by a corrective action. The movements of the target, or at least the set-up errors are corrected by moving the treatment table, corresponding to the simplest and most validated IGRT modality in a standard practice. The deformations of the target volume and organs at risk are however much more common, and unfortunately much more complicated to consider, requiring multiple planning before or during the treatment, corresponding to the adaptive radiotherapy strategies. The planning target volume must be carefully chosen according to these anatomic variations. This article reviews the modalities of IGRT, standard or under evaluation, according to the different tumour sites.

  17. Biological nurse specialist: goodwill to good practice.

    PubMed

    Palmer, Deborah; El Miedany, Yasser

    The extensive use of biological agents in recent years for the treatment of rheumatological diseases has required a steep learning curve for the specialist nurses who manage and work in this specialty. Safe prescribing of biological therapies requires good infrastructure and specialist nursing personnel. With additional training, the specialist nurse may take responsibility for a number of tasks in the patient pathway including screening, treatment administration, patient education, prescription coordination for home drug delivery, patient support, monitoring and data collection. Biological treatment is becoming more widely used in several specialities, in particular gastroenterology, dermatology and ophthalmology. Since 2002, rheumatology specialist nurses have taken the lead in assessment and providing biologic therapy, not only for patients suffering from rheumatic diseases but also for those with immune-mediated inflammatory disorders. The unique nature and variable safety profiles of these agents led to the development of immune-mediated inflammatory disease infusion (IMID) centres and highlighted the importance of having biological specialist nurses. This article will discuss the evolution of the IMID/biologic specialist nurse role and how IMID services started with goodwill from the rheumatology nurse specialists to develop into a main component of the holistic approach to care.

  13. Practical application of remote sensing in agriculture

    NASA Technical Reports Server (NTRS)

    Phelps, R. A.

    1975-01-01

    Remote sensing program imagery from several types of platforms, from light aircraft to the LANDSAT (ERTS) satellites, have been utilized during the past few years, with preference for inexpensive imagery over expensive magnetic tapes. Emphasis has been on practical application of remote sensing data to increase crop yield by decreasing plant stress, disease, weeds and undesirable insects and by improving irrigation. Imagery obtained from low altitudes via aircraft provides the necessary resolution and complements but does not replace data from high altitude aircraft, Gemini and Apollo spacecraft, Skylab space station and LANDSAT satellites. Federal government centers are now able to supply imagery within about thirty days from data of order. Nevertheless, if the full potential of space imagery in practical agricultural operations is to be realized, the time span from date of imaging to user application needs to be shortened from the current several months to not more than two weeks.

  15. Is international agricultural research a global public good? The case of rice biofortification.

    PubMed

    Brooks, Sally

    2011-01-01

    The status of international agricultural research as a global public good (GPG) has been widely accepted since the Green Revolution of the 1960s and 1970s. While the term was not used at the time of its creation, the Consultative Group on International Agricultural Research (CGIAR) system that evolved at that time has been described as a 'prime example of the promise, performance and perils of an international approach to providing GPGs'. Contemporary literature on international agricultural research as a GPG tends to support this view and focuses on how to operationalize the concept. This paper adopts a different starting point and questions this conceptualization of the CGIAR and its outputs. It questions the appropriateness of such a 'neutral' concept to a system born of the imperatives of Cold War geopolitics, and shaped by a history of attempts to secure its relevance in a changing world. This paper draws on a multi-sited, ethnographic study of a research effort highlighted by the CGIAR as an exemplar of GPG-oriented research. Behind the ubiquitous language of GPGs, 'partnership' and 'consensus', however, new forms of exclusion and restriction are emerging within everyday practice, reproducing North-South inequalities and undermining the ability of these programmes to respond to the needs of projected beneficiaries.

Sustainability means that the software used today will be available - and continue to be improved and supported - in the future. We report here an initial set of metrics that measure good practices in software development. This initiative differs from previously developed efforts in being a community-driven grassroots approach where experts from different organisations propose good software practices that have reasonable potential to be adopted by the communities they represent. We not only focus our efforts on understanding and prioritising good practices, we assess their feasibility for implementation and publish them here. PMID:27635232

  13. Management Documentation: Indicators & Good Practice at Cultural Heritage Places

    NASA Astrophysics Data System (ADS)

    Eppich, R.; Garcia Grinda, J. L.

    2015-08-01

    Documentation for cultural heritage places usually refers to describing the physical attributes, surrounding context, condition or environment; most of the time with images, graphics, maps or digital 3D models in their various forms with supporting textural information. Just as important as this type of information is the documentation of managerial attributes. How do managers of cultural heritage places collect information related to financial or economic well-being? How are data collected over time measured, and what are significant indicators for improvement? What quality of indicator is good enough? Good management of cultural heritage places is essential for conservation longevity, preservation of values and enjoyment by the public. But how is management documented? The paper will describe the research methodology, selection and description of attributes or indicators related to good management practice. It will describe the criteria for indicator selection and why they are important, how and when they are collected, by whom, and the difficulties in obtaining this information. As importantly it will describe how this type of documentation directly contributes to improving conservation practice. Good practice summaries will be presented that highlight this type of documentation including Pamplona and Ávila, Spain and Valletta, Malta. Conclusions are drawn with preliminary recommendations for improvement of this important aspect of documentation. Documentation of this nature is not typical and presents a unique challenge to collect, measure and communicate easily. However, it is an essential category that is often ignored yet absolutely essential in order to conserve cultural heritage places.

  14. Health physics manual of good practices for accelerator facilities

    SciTech Connect

    Casey, W.R.; Miller, A.J.; McCaslin, J.B.; Coulson, L.V.

    1988-04-01

    It is hoped that this manual will serve both as a teaching aid as well as a useful adjunct for program development. In the context of application, this manual addresses good practices that should be observed by management, staff, and designers since the achievement of a good radiation program indeed involves a combined effort. Ultimately, radiation safety and good work practices become the personal responsibility of the individual. The practices presented in this manual are not to be construed as mandatory rather they are to be used as appropriate for the specific case in the interest of radiation safety. As experience is accrued and new data obtained in the application of this document, ONS will update the guidance to assure that at any given time the guidance reflects optimum performance consistent with current technology and practice.The intent of this guide therefore is to: define common health physics problems at accelerators; recommend suitable methods of identifying, evaluating, and managing accelerator health physics problems; set out the established safety practices at DOE accelerators that have been arrived at by consensus and, where consensus has not yet been reached, give examples of safe practices; introduce the technical literature in the accelerator health physics field; and supplement the regulatory documents listed in Appendix D. Many accelerator health physics problems are no different than those at other kinds of facilities, e.g., ALARA philosophy, instrument calibration, etc. These problems are touched on very lightly or not at all. Similarly, this document does not cover other hazards such as electrical shock, toxic materials, etc. This does not in any way imply that these problems are not serious. 160 refs.

  15. A model for reflection for good clinical practice.

    PubMed

    Balla, John I; Heneghan, Carl; Glasziou, Paul; Thompson, Matthew; Balla, Margaret E

    2009-12-01

    Rationale and aim The rapidly changing knowledge base of clinical practice highlights the need to keep abreast of knowledge changes that are most relevant for the practitioner. We aimed to develop a model for reflection on clinical practice that identified the key elements of medical knowledge needed for good medical practice. Method The dual theory of cognition, an integration of intuitive and analytic processes, provided the framework for the study. The design looked at the congruence between the clinical thinking process and the dual theory. A one-year study was conducted in general practice clinics in Oxfordshire, UK. Thirty-five general practitioners participated in 20-minute interviews to discuss how they worked through recently seen clinical cases. Over a one-year period 72 cases were recorded from 35 interviews. These were categorized according to emerging themes, which were manually coded and substantiated with verbatim quotations. Results There was a close fit between the dual theory and participants' clinical thinking processes. This included instant problem framing, consistent with automatic intuitive thinking, focusing on the risk and urgency of the case. Salient features accounting for these choices were recognizable. There was a second reflective phase, leading to the review of initial judgements. Conclusions The proposed model highlights the critical steps in decision making. This allows regular recalibration of knowledge that is most critical at each of these steps. In line with good practice, the model also links the crucial knowledge used in decision making, to value judgments made in relation to the patient.

    The purpose of the Department of Energy (DOE) Guide to Good Practices for On-the-Job Training (OJT) is to provide DOE contractor organizations with information that can be used to modify existing programs or to develop new programs. This guide replaces the Guide to Good Practices for On-the-Job Training that was distributed to DOE and DOE contractors in 1987. DOE contractors should not feel obligated to adopt all parts of this guide. Rather, they can use the information in this guide to develop programs that apply to their facility. This guide can be used as an aid in the design and development of a facility's OJT programs and to assist the instructors who conduct OJT and performance tests in the areas of facility operations, maintenance, and technical supports.

  17. Defending the four principles approach as a good basis for good medical practice and therefore for good medical ethics.

    PubMed

    Gillon, Raanan

    2015-01-01

    This paper argues that the four prima facie principles-beneficence, non-maleficence, respect for autonomy and justice-afford a good and widely acceptable basis for 'doing good medical ethics'. It confronts objections that the approach is simplistic, incompatible with a virtue-based approach to medicine, that it requires respect for autonomy always to have priority when the principles clash at the expense of clinical obligations to benefit patients and global justice. It agrees that the approach does not provide universalisable methods either for resolving such moral dilemmas arising from conflict between the principles or their derivatives, or universalisable methods for resolving disagreements about the scope of these principles-long acknowledged lacunae but arguably to be found, in practice, with all other approaches to medical ethics. The value of the approach, when properly understood, is to provide a universalisable though prima facie set of moral commitments which all doctors can accept, a basic moral language and a basic moral analytic framework. These can underpin an intercultural 'moral mission statement' for the goals and practice of medicine.

    2016-01-01

    Over the past 15 years, chromatographic techniques with mass spectrometric detection have been increasingly used to monitor the rapidly expanded list of regulated flavour and fragrance ingredients. This trend entails a need for good quantification practices suitable for complex media, especially for multi-analytes. In this article, we present experimental precautions needed to perform the analyses and ways to process the data according to the most recent approaches. This notably includes the identification of analytes during their quantification and method validation, when applied to real matrices, based on accuracy profiles. A brief survey of application studies based on such practices is given. This article is part of the themed issue ‘Quantitative mass spectrometry’. PMID:27644977

    A doubling in global food demand projected for the next 50 years poses huge challenges for the sustainability both of food production and of terrestrial and aquatic ecosystems and the services they provide to society. Agriculturalists are the principal managers of global usable lands and will shape, perhaps irreversibly, the surface of the Earth in the coming decades. New incentives and policies for ensuring the sustainability of agriculture and ecosystem services will be crucial if we are to meet the demands of improving yields without compromising environmental integrity or public health.

    The participation of minors in biobank research can offer great benefits for science and health care. However, as minors are a vulnerable population they are also in need of adequate protective measures when they are enrolled in research. Research using biobanked biological samples from children poses additional ethical issues to those raised by research using adult biobanks. For example, small children have only limited capacity, if any, to understand the meaning and implications of the research and to give a documented agreement to it. Older minors are gradually acquiring this capacity. We describe principles for good practice related to the inclusion of minors in biobank research, focusing on issues related to benefits and subsidiarity, consent, proportionality and return of results. Some of these issues are currently heavily debated, and we conclude by providing principles for good practice for policy makers of biobanks, researchers and anyone involved in dealing with stored tissue samples from children. Actual implementation of the principles will vary according to different jurisdictions. PMID:22713814

    In 2005, the Working Group for the Survey and Utilisation of Secondary Data (AGENS) of the German Society for Social Medicine and Prevention (DGSMP) and the German Society for Epidemiology (DGEpi) first published "Good Practice in Secondary Data Analysis (GPS)" formulating a standard for conducting secondary data analyses. GPS is intended as a guide for planning and conducting analyses and can provide a basis for contracts between data owners. The domain of these guidelines does not only include data routinely gathered by statutory health insurance funds and further statutory social insurance funds, but all forms of secondary data. The 11 guidelines range from ethical principles and study planning through quality assurance measures and data preparation to data privacy, contractual conditions and responsible communication of analytical results. They are complemented by explanations and practical assistance in the form of recommendations. GPS targets all persons directing their attention to secondary data, their analysis and interpretation from a scientific point of view and by employing scientific methods. This includes data owners. Furthermore, GPS is suitable to assess scientific publications regarding their quality by authors, referees and readers. In 2008, the first version of GPS was evaluated and revised by members of AGENS and the Epidemiological Methods Working Group of DGEpi, DGSMP and GMDS including other epidemiological experts and had then been accredited as implementation regulations of Good Epidemiological Practice (GEP). Since 2012, this third version of GPS is on hand and available for downloading from the DGEpi website at no charge. Especially linguistic specifications have been integrated into the current revision; its internal consistency was increased. With regards to contents, further recommendations concerning the guideline on data privacy have been added. On the basis of future developments in science and data privacy, further revisions will

    A review of the origin of GLP (Good Laboratory Practice) and ISO (International Standard Organisation) directives is followed by a number of definitions of concepts such as quality, guarantees of quality, quality systems, etc. by laboratories (NEN 2653). These requirements are discussed in the paper. Certification is one of the guarantees of quality assessment by laboratories. Certification of laboratories is carried out by STERLAB (Laboratory Accreditation Board of The Netherlands) or the CCKL (National Coordination Committee for Quality Assurance for Health Care Laboratories in The Netherlands). In addition to certification, laboratories in the Netherlands are extremely active as regards external quality control (QC). QC is carried out by the various occupational groups. The paper finally closes with a discussion of future developments regarding quality control and certification in medical and veterinary diagnostic laboratories.

In this review article, key aspects of GCP and the responsibilities of investigators, monitors and sponsors are described. In addition, a comprehensive overview of the historical background on the development of GCP from the US Pure Food and Drugs Act of 1906 over the Nuremberg Code, the Kefauver-Harris Amendments and the Declaration of Helsinki until now is given. Knowledge of the historical background may help understand the developments in GCP.

    Good practice in health, environment and safety management in enterprise (GP HESME) is a process that aims at continuous improvement in health, environment and safety performance, involving all stakeholders within and outside the enterprise. This WHO program is supported by other international organizations, and the declaration of Ministers of Health and Ministers of Environment adopted in 1999. The basic issues of the GP HESME concept are presented as well as its prerequisites, benefits and participants. The key partners in GP HESME are employers and their organizations, representatives of employees, governmental agencies, local authorities, financial and insurance institutions, occupational health services, environmental and social services, associations of professionals, research and training institutions. The HESME system is intended to function at different levels: international, national, local community, and enterprise settings. The lists of expected benefits for each group of stakeholders are discussed. Evaluation of GP HESME is based on the criteria and indicators, the most important of them are briefly presented.

  14. Good Practice Guide Waste Minimization/Pollution Prevention

    1999-10-14

    This Good Practice Guide provides tools, information, and examples for promoting the implementation of pollution prevention during the design phases of U.S. Department of Energy (DOE) projects. It is one of several Guides for implementing DOE Order 430.1, Life-cycle Asset Management. DOE Order 430.1 provides requirements for DOE, in partnership with its contractors, to plan, acquire, operate, maintain, and dispose of physical assets. The goals of designing for pollution prevention are to minimize raw material consumption, energy consumption, waste generation, health and safety impacts, and ecological degradation over the entire life of the facility (EPA 1993a). Users of this Guide will learn to translate national policy and regulatory requirements for pollution prevention into action at the project level. The Guide was written to be applicable to all DOE projects, regardless of project size or design phase. Users are expected to interpret the Guide for their individual project's circumstances, applying a graded approach so that the effort is consistent with the anticipated waste generation and resource consumption of the physical asset. This Guide employs a combination of pollution prevention opportunity assessment (PPOA) methods and design for environment (DfE) philosophies. The PPOA process was primarily developed for existing products, processes, and facilities. The PPOA process has been modified in this Guide to address the circumstances of the DOE design process as delineated in DOE Order 430.1 and its associated Good Practice Guides. This modified form of the PPOA is termed the Pollution Prevention Design Assessment (P2DA). Information on current nationwide methods and successes in designing for the environment also have been reviewed and are integrated into this guidance.

  15. Harmonization of good laboratory practice requirements and laboratory accreditation programs.

    1994-09-01

    Efforts to harmonize Good Laboratory Practice (GLP) requirements have been underway through the Organization for Economic Cooperation and Development (OECD) since 1981. In 1985, a GLP panel was established to facilitate the practical implementation of the OECD/GLP program. Through the OECD/GLP program, Memoranda of Understanding (MOU) agreements which foster requirements for reciprocal data and study acceptance and unified GLP standards have been developed among member countries. Three OECD Consensus Workshops and three inspectors training workshops have been held. In concert with these efforts, several OECD countries have developed GLP accreditation programs, managed by local health and environmental ministries. In addition, Canada and the United States are investigating Laboratory Accreditation programs for environmental monitoring assessment and GLP-regulated studies. In the European Community (EC), the need for quality standards specifying requirements for production and international trade has promoted International Standards Organization (ISO) certification for certain products. ISO-9000 standards identify requirements for certification of quality systems. These certification programs may affect the trade and market of laboratories conducting GLP studies. Two goals identified by these efforts are common to both programs: first, harmonization and recognition of requirements, and second, confidence in the rigor of program components used to assess the integrity of data produced and study activities. This confidence can be promoted, in part, through laboratory inspection and screening processes. However, the question remains, will data produced by sanctioned laboratories be mutually accepted on an international basis?(ABSTRACT TRUNCATED AT 250 WORDS)

    The booklet presents the results of a project conducted by EPA's Office of Ground-Water Protection to evaluate the potential impacts of various agronomic, irrigation, and pesticide application practices on ground water. The report provides State and local water quality and agricultural officials with technical information to help in the development of programs to protect ground water from pesticide contamination. The report explains the principles involved in reducing the risk of pesticide contamination and describes what is known about the impact of various agricultural practices on pesticide leaching. It is hoped that the information will be helpful to water-quality officials in developing and implementing ground-water protection programs.

    A Good Clinical Practices (GCPs) course, based on the combination of theoretical modules with a practical training in real-life conditions, was held in 2010 in Burkina Faso. It was attended by 15 trainees from nine African, Asian, and Latin American countries. There were some discrepancies between the average good results at the end of the theoretical phase and the GCP application during the first days of the practical phase, underlying the difficulties of translating theoretical knowledge into good practices. Most of the findings were not unexpected and reflected the challenges commonly faced by clinical investigators in resource-poor contexts (i.e., the high workload at peripheral health facilities, the need to conciliate routine clinical activities with clinical research, and the risk of creating a double standard among patients attending the same health facility [free care for recruited patients versus user fees for non-recruited patients with the same medical condition]). Even if limited in number and time, these observations suggest that a theoretical training alone may not be sufficient to prepare trainees for the challenges of medical research in real-life settings. Conversely, when a practical phase immediately follows a theoretical one, trainees can immediately experience what the research methodology implicates in terms of work organization and relationship with recruited and non-recruited patients. This initial experience shows the complexity of translating GCP into practice and suggests the need to rethink the current conception of GCP training.

    1997-01-01

    While the methodology used in developing test items can vary significantly, to ensure quality examinations, test items should be developed systematically. Test design and development is discussed in the DOE Guide to Good Practices for Design, Development, and Implementation of Examinations. This guide is intended to be a supplement by providing more detailed guidance on the development of specific test items. This guide addresses the development of written examination test items primarily. However, many of the concepts also apply to oral examinations, both in the classroom and on the job. This guide is intended to be used as guidance for the classroom and laboratory instructor or curriculum developer responsible for the construction of individual test items. This document focuses on written test items, but includes information relative to open-reference (open book) examination test items, as well. These test items have been categorized as short-answer, multiple-choice, or essay. Each test item format is described, examples are provided, and a procedure for development is included. The appendices provide examples for writing test items, a test item development form, and examples of various test item formats.

    Summary Application of cell therapies in burn care started in the early 80s in specialized hospital centers world-wide. Since 2007, cell therapies have been considered as “Advanced Therapy Medicinal Products” (ATMP), so classified by European Directives along with associated Regulations by the European Parliament. Consequently, regulatory changes have transformed the standard linear clinical care pathway into a more complex one. It is important to ensure the safety of cellular therapies used for burn patients and to standardize as much as possible the cell sources and products developed using cell culture procedures. However, we can definitely affirm that concentrating the bulk of energy and resources on the implementation of Good Manufacturing Practice (GMP) alone will have a major negative impact on the care of severely burned patients world-wide. Developing fully accredited infrastructures and training personnel (required by the new directives), along with obtaining approval for clinical trials to go ahead, can be a lengthy process.We discuss whether or not these patients could benefit from cell therapies provided by standard in-hospital laboratories, thus avoiding having to meet rigid regulations concerning the use of industrial pharmaceutical products. “Hospital Exemption” could be a preferred means to offer burn patients a customized and safe product, as many adaptations may be required throughout their treatment pathway. Patients who are in need of rapid treatment will be the ones to suffer the most from regulations intended to help them. PMID:28149232

    Due to the limitations of pre-authorization clinical trials, the safety information obtained from them is relatively limited. Therefore, it is very necessary to carry out pharmacovigilance activities on drugs post-marketing. In order to promote the specific implementation of the new pharmacovigilance regulations, the European medicines agency (EMA) developed the Guideline on Good Pharmacovigilance Practices (GVP), as the new criteria for pharmacovigilance in the European Union (EU). Compared with the previously published, Guidelines on Pharmacovigilance for Medicinal Products for Human Use (2007), the GVP proposed more comprehensive and systematic provisions of pharmacovigilance systems, quality control systems, judgements, pharmacovigilance inspections and audits. In addition, it set more specific and comprehensive requirements on risk management systems, the management and reporting of adverse reactions to medicinal products, periodic safety update reports, post-authorization safety studies, signal management, and so on. Interpreting the basic principles, working mechanisms, key technologies and methods of the GVP provides a useful reference for us to carry out pharmacovigilance (especially regarding safety monitoring of parenterally administered Chinese medicine).

    The Macedonian Academy of Sciences and Arts (MASA), held a scientific workshop for journal editors in biomedicine: "Publishing integrity and good practices in editing in biomedicine" on April 25, 2014 in MASA, Skopje. The meeting looked into old problems and new situations in editing and publishing, with emphasis on the situation in developing countries. This global knowledge-based society is founded on the results obtained from scientific research. The data from basic research in developed countries contribute in a quite substantial manner to the newly added economic value. One of the main reasons for underdevelopment in South Eastern Europe (SEE) is certainly a low or non-existent contribution of scientific research in the newly added economic value. This has largely to do with the perception of the political elites which simply lack the insight on the crucial importance of science in development. In the long term this leads to societies in which there are distortions in the understanding of the most basic values. Academic publishing has experienced tremendous growth: so far there are at least 50 million scientific articles. Interestingly, publishing in developing countries has experienced a rate of growth higher than in developed countries. However, this is not the case with the Balkan countries. The meeting looked at some old and some newly emerging problems in editing and publishing. First, the high cost for universities and researchers to purchase journals adversely affects both publishing and editing. In developing countries the high cost of purchasing scientific literature is an almost insurmountable problem in spite of the fact that some publishing companies offer discounted fees. Open access journals in South Eastern European (SEE) countries are hardly achievable as this also incurs costs that have to be covered in some way or other. The peer review process has the fundamental difficulty that reviewers are in the situation of a Procrustean bed, tending to

    Agricultural practices can result in differences in organic matter (OM) and agricultural chemical inputs in adjacent ditches, but its indirect effects on OM composition and its inherent consequences for ecosystem functioning remain uncertain. This study determined the effect of agricultural practices (dairy farm grasslands and hyacinth bulb fields) on OM degradation by microorganisms and invertebrates with a consumption and food preference experiment in the field and in the laboratory using natural OM collected from the field. Freshly cut grass and hyacinths were also offered to control for OM composition and large- and small mesh-sizes were used to distinguish microbial decomposition and invertebrate consumption. Results show that OM decomposition by microorganisms and consumption by invertebrates was similar throughout the study area, but that OM collected from ditches adjacent grasslands and freshly cut grass and hyacinths were preferred over OM collected from ditches adjacent to a hyacinth bulb field. In the case of OM collected from ditches adjacent hyacinth bulb fields, both microbial decomposition and invertebrate consumption were strongly retarded, likely resulting from sorption and accumulation of pesticides. This outcome illustrates that differences in agricultural practices can, in addition to direct detrimental effects on aquatic organisms, indirectly alter the functioning of adjacent aquatic ecosystems.

    In this paper, we examine the impact of implementing three systemic practices on the diversity and institutional culture in biomedical and public health PhD training at Brown University. We hypothesized that these practices, designed as part of the National Institutes of Health-funded Initiative to Maximize Student Development (IMSD) program in the Division of Biology and Medicine, would have a positive effect on underrepresented minority (URM) recruitment and retention and objective measures of student success. These practices include: 1) develop strategic partnerships with selected undergraduate institutions; 2) provide a personalized education program of student support and skill-based modules to supplement discipline-based course work; and 3) transform institutional culture by engaging faculty in supporting diversity-related goals and practices. Data comparing URM numbers and key academic milestones before and after implementation of IMSD practices support the initial hypothesis and effectiveness of these practices at Brown. Program components are broadly applicable as best practices for others seeking to improve URM recruitment and achievements of graduate students traditionally underrepresented in the sciences.

    The goal of this study is to clarify research needs and identify effective practices for enhancing soil health. This was done by a synopsis of soil literature that specifically tests practices designed to maintain or enhance elements of soil health. Using an expert panel of soil scientists and practitioners, we then assessed the evidence in the soil synopsis to highlight practices beneficial to soil health, practices considered detrimental, and practices that need further investigation. A partial Spearman's correlation was used to analyse the panel's responses. We found that increased certainty in scientific evidence led to practices being considered to be more effective due to them being empirically justified. This suggests that for practices to be considered effective and put into practice, a substantial body of research is needed to support the effectiveness of the practice. This is further supported by the high proportion of practices (33 %), such as changing the timing of ploughing or amending the soil with crops grown as green manures, that experts felt had unknown effectiveness, usually due to insufficiently robust evidence. Only 7 of the 27 reviewed practices were considered to be beneficial, or likely to be beneficial in enhancing soil health. These included the use of (1) integrated nutrient management (organic and inorganic amendments); (2) cover crops; (3) crop rotations; (4) intercropping between crop rows or underneath the main crop; (5) formulated chemical compounds (such as nitrification inhibitors); (6) control of traffic and traffic timing; and (7) reducing grazing intensity. Our assessment, which uses the Delphi technique, is increasingly used to improve decision-making in conservation and agricultural policy, identified practices that can be put into practice to benefit soil health. Moreover, it has enabled us to identify practices that need further research and a need for increased communication between researchers, policy-makers, and

    Abstract Objective: to identify the factors related to the quality of umbilical cord and placental blood specimens, and define best practices for their collection in a government bank of umbilical cord and placental blood. Method: this was a descriptive study, quantitative approach, performed at a government umbilical cord and placental blood bank, in two steps: 1) verification of the obstetric, neonatal and operational factors, using a specific tool for gathering data as non-participant observers; 2) definition of best practices by grouping non-conformities observed before, during and after blood collection. The data was analyzed using descriptive statistics and the following statistical software: Statistica(r) and R(r). Results: while there was a correlation with obstetrical and neonatal factors, there was a larger correlation with operational factors, resulting in the need to adjust the professional practices of the nursing staff and obstetrical team involved in collecting this type of blood. Based on these non-conformities we defined best practices for nurses before, during and after blood collection. Conclusion: the best practices defined in this study are an important management tool for the work of nurses in obtaining blood specimens of high cell quality. PMID:27556876

    2015-02-01

    A major share of the area of hypoxic growth in the Northern Gulf of Mexico has been attributed to nutrient run-off from agricultural fields, but no estimate is available for the cost of reducing Gulf hypoxic area using agricultural conservation practices. We apply the Soil and Water Assessment Tool using observed daily weather to simulate the reduction in nitrogen loading in the Upper Mississippi River Basin (UMRB) that would result from enrolling all row crop acreage in the Conservation Reserve Program (CRP). Nitrogen loadings at the outlet of the UMRB are used to predict Gulf hypoxic area, and net cash farm rent is used as the price for participation in the CRP. Over the course of the 42 year simulation, direct CRP costs total more than $388 billion, and the Inter-Governmental Task Force goal of hypoxic area less than 5000 square kilometers is met in only two years.

    Renfrew, R.B.; Ribic, C.A.

    2001-01-01

    Rotational grazing has been proposed as a Best Management Practice (BMP) for minimizing runoff in Wisconsin agricultural riparian areas. The influence of this land management practice on grassland birds has not been evaluated in relation to more traditional agricultural land management systems in Midwestern riparian areas. This study compared the grassland bird community in riparian areas in Wisconsin that were rotationally grazed to 2 common land use practices along streams in Wisconsin: continuously grazed pastures and rowcrop fields with 10-m-wide ungrazed buffer strips located along the stream. We calculated total number of birds, the Berger-Parker Index of Dominance, and number of birds ha-1 for each site. Vegetation variables used were height-density, litter depth, and percent bare ground. Bird species richness, species dominance, and density did not differ among land use types. In contrast, grassland bird species of management concern [Savannah Sparrow (Passerculus sandwichensis Gmelin), Eastern Meadowlark (Sturnella magna L.), and Bobolink (Dolichonyx oryzivorus L.)] were found on continuous and rotational pastures but very rarely or never occurred on buffer strips. Contrary to previous research, however, rotationally grazed pastures did not support more of these species than continuously grazed pastures. Bird density was related to vegetation structure, with higher densities found on sites with deeper litter. Within the pasture land use types, there were no consistent differences between species richness and density near the stream (10 m).

    The major decrease in grassland surfaces associated with changes in their management that has been observed in many regions of the earth during the last half century has major impacts on environmental and socio-economic systems. This study focuses on the identification of grassland management practices in an intensive agricultural watershed located in Brittany, France, by analyzing the intra-annual dynamics of the surface condition of vegetation using remotely sensed and field data. We studied the relationship between one vegetation index (NDVI) and two biophysical variables (LAI and fCOVER) derived from a series of three SPOT images on one hand and measurements collected during field campaigns achieved on 120 grasslands on the other. The results show that the LAI appears as the best predictor for monitoring grassland mowing and grazing. Indeed, because of its ability to characterize vegetation status, LAI estimated from remote sensing data is a relevant variable to identify these practices. LAI values derived from the SPOT images were then classified based on the K-Nearest Neighbor (KNN) supervised algorithm. The results points out that the distribution of grassland management practices such as grazing and mowing can be mapped very accurately (Kappa index = 0.82) at a field scale over large agricultural areas using a series of satellite images.

    It is incredibly easy to ignore the medical practice team that is doing a good job. However, when we allow good performers to continue as they are, they probably won't improve. Their performance may even worsen. This is unfortunate because with a little bit of effort and support, good performers can often learn to excel. This article offers 12 techniques medical practice managers can use to bring their team members from good performance to excellent. It describes how to use goal-setting, work assignments, modeling, confidence building, team retreats, rewards, incentives, and reinforcement to ratchet up a good medical practice team's performance. This article also identifies the signs of medical employee mediocrity. It describes why setting higher expectations of your medical practice employees will ultimately improve their performance. Finally, this article suggests 10 practical and affordable strategies that medical practice managers can use to reinforce excellent performance in their good employees.

    The most prevalent nutritional disorder in fruit tree crops growing in calcareous soils is Fe deficiency chlorosis. Iron-deficient, chlorotic tree orchards require Fe-fertilization, since chlorosis causes decreases in tree vegetative growth as well as fruit yield and quality losses. When assessing the effectiveness of Fe-fertilizers, it is necessary to use sound practices based in the state-of-the art knowledge on the physiology and biochemistry of Fe deficiency. This review provides an overview on how to carry out the assessment of the efficiency of Fe-fertilizers, discussing common errors found in the literature, outlining adequate procedures and giving real examples of practical studies carried out in our laboratory in the past decade. The review focuses on: i) the design of Fe-fertilization experiments, discussing several issues such as the convenience of using controlled conditions or field experiments, whether fertilizer assessment experiments should mimic usual fertilization practices, as well as aspects regarding product formulations, dosages, control references and number of replicates; ii) the assessment of chlorosis recovery upon Fe-fertilization by monitoring leaf chlorophyll, and iii) the analysis of the plant responses upon Fe-fertilization, discussing the phases of leaf chlorosis recovery and the control of other leaf nutritional parameters.

    2015-01-01

    An efficient classification framework for mapping agricultural tillage practice using hyperspectral remote sensing imagery is proposed, which has the potential to be implemented practically to provide rapid, accurate, and objective surveying data for precision agricultural management and appraisal from large-scale remote sensing images. It includes a local region filter [i.e., Gaussian low-pass filter (GLF)] to extract spatial-spectral features, a dimensionality reduction process [i.e., local fisher's discriminate analysis (LFDA)], and the traditional k-nearest neighbor (KNN) classifier, and is denoted as GLF-LFDA-KNN. Compared to our previously used local average filter and adaptive weighted filter, the GLF also considers spatial features in a small neighborhood, but it emphasizes the central pixel itself and is data-independent; therefore, it can achieve the balance between classification accuracy and computational complexity. The KNN classifier has a lower computational complexity compared to the traditional support vector machine (SVM). After classification separability is enhanced by the GLF and LFDA, the less powerful KNN can outperform SVM and the overall computational cost remains lower. The proposed framework can also outperform the SVM with composite kernel (SVM-CK) that uses spatial-spectral features.

    Magnetoencephalographic (MEG) recordings are a rich source of information about the neural dynamics underlying cognitive processes in the brain, with excellent temporal and good spatial resolution. In recent years there have been considerable advances in MEG hardware developments and methods. Sophisticated analysis techniques are now routinely applied and continuously improved, leading to fascinating insights into the intricate dynamics of neural processes. However, the rapidly increasing level of complexity of the different steps in a MEG study make it difficult for novices, and sometimes even for experts, to stay aware of possible limitations and caveats. Furthermore, the complexity of MEG data acquisition and data analysis requires special attention when describing MEG studies in publications, in order to facilitate interpretation and reproduction of the results. This manuscript aims at making recommendations for a number of important data acquisition and data analysis steps and suggests details that should be specified in manuscripts reporting MEG studies. These recommendations will hopefully serve as guidelines that help to strengthen the position of the MEG research community within the field of neuroscience, and may foster discussion in order to further enhance the quality and impact of MEG research.

  8. Enteral tube feeding: using good practice to prevent infection.

    PubMed

    Malhi, Hardip

    2017-01-12

    Enteral tube feeding is the delivery of nutritionally complete feed via a tube into the gut. It is used for patients who are unable to meet their nutritional needs orally. Enteral feeding can be given through a variety of different tubes that access the gastrointestinal tract either via the stomach or the small bowel. The contamination of enteral feed can often be overlooked as a source of bacterial infection. Enteral feeds can become contaminated in a variety of different ways. Most often infections result in extended lengths of stay in hospital and patients also need additional therapies and treatments in order to resolve these infections. Healthcare-associated infections not only affect the patients who acquire them but also have an impact on the staff involved in their care. Each acute trust will have its own local policies and guidelines regarding enteral feeding and infection control and prevention. These local documents will be based on national initiatives and guidelines. It is important for nurses to refer to their local policies and guidelines before they start a patient on enteral feeding to ensure that they are doing so in the safest manner possible. Nurses' practice is key to preventing bacterial contamination in such patients.

    Models--mathematical frameworks that facilitate estimation of the consequences of health care decisions--have become essential tools for health technology assessment. Evolution of the methods since the first ISPOR Modeling Task Force reported in 2003 has led to a new Task Force, jointly convened with the Society for Medical Decision Making, and this series of seven articles presents the updated recommendations for best practices in conceptualizing models; implementing state-transition approaches, discrete event simulations, or dynamic transmission models; and dealing with uncertainty and validating and reporting models transparently. This overview article introduces the work of the Task Force, provides all the recommendations, and discusses some quandaries that require further elucidation. The audience for these articles includes those who build models, stakeholders who utilize their results, and, indeed, anyone concerned with the use of models to support decision making.

    Good Distribution Practice is based on the Directive of the Board of the European Community 92/25/EEC regarding the wholesale distribution of drugs for human consumption. It is stated in the Directive that the whole drug distribution channel is to be controlled from the point of drug production or import down to the supplies to the end user. In order to reach the goal, the drug distribution company must create the quality assurance system and facilitate its correct functioning. This aim requires development of the rules of the Good Distribution Practice. Those rules set the general requirements of the Good Distribution Practice for distribution companies that they must conduct. The article explains main requirements postulated in the rules of the Good Distribution Practice and implementation of the Good Distribution Practice requirements in drug distribution companies.

    Agricultural practices pose threats to biotic diversity in freshwater systems with increasing use of glyphosate-based herbicides for weed control and animal waste for soil amendment becoming common in many regions. Over the past two decades, these particular agricultural trends have corresponded with marked declines in populations of fish and mussel species in the Upper Conasauga River watershed in Georgia/Tennessee, USA. To investigate the potential role of agriculture in the population declines, surface waters and sediments throughout the basin were tested for toxicity and analyzed for glyphosate, metals, nutrients, and steroid hormones. Assessments of chronic toxicity with Ceriodaphnia dubia and Hyalella azteca indicated that few water or sediment samples were harmful and metal concentrations were generally below impairment levels. Glyphosate was not observed in surface waters, although its primary degradation product, aminomethyl phosphonic acid (AMPA), was detected in 77% of the samples (mean = 509 μg/L, n = 99) and one or both compounds were measured in most sediment samples. Waterborne AMPA concentrations supported an inference that surfactants associated with glyphosate may be present at levels sufficient to affect early life stages of mussels. Nutrient enrichment of surface waters was widespread with nitrate (mean = 0.7 mg NO3-N/L, n = 179) and phosphorus (mean = 275 μg/L, n = 179) exceeding levels associated with eutrophication. Hormone concentrations in sediments were often above those shown to cause endocrine disruption in fish and appear to reflect the widespread application of poultry litter and manure. Observed species declines may be at least partially due to hormones, although excess nutrients and herbicide surfactants may also be implicated.

    Good Distribution Practice of medicinal products for human use is a quality warranty system, which includes requirements for purchase, receiving, storage and export of drugs, intended human consumption. A drug is a specific product and its mishandling is dangerous to human health and life. Therefore it is necessary to strictly control the movement of the drug from the producer to the consumer so that poor quality drugs do not have access to the market. Good Distribution Practice rules set the general requirements for good wholesale distribution practice of drugs, intended for human consumption. In order for company to meet the specified requirements, the drug distribution company must have all suitable and necessary premises, machinery, equipment, the required number of employees and specified documentation. The preparation of the Good Distribution Practice documentation is one of the most important and complex aspects when implementing the Good Distribution Practice in the companies. The article deals with the analysis of results obtained during the research of drug distribution companies in Lithuania. The research revealed that drug distribution companies put emphasis on the equipment of storage premises. Less attention is being paid to the preparation of the documents of Good Distribution Practice. The article thus presents the analysis of Good Distribution Practice documents prepared by the drug distribution companies.

    This impact of alternative management practices on agricultural soil C is estimated by a soil C mass balance modeling study that incorporates policy considerations in the analysis. A literature review of soil C modeling and impacts of management practices has been completed. The models selected for use and/or modification to meet the needs of representing soil C cycles in agroecosystems and impacts of management practices are CENTURY and DNDC. These models share a common ability to examine the impacts of alternative management practices on soil organic C, and are readily accessible. An important aspect of this effort is the development of the modeling framework and methodology that define the agricultural production systems and scenarios (i.e., crop-soil-climate combinations) to be assessed in terms of national policy, the integration of the model needs with available databases, and the operational mechanics of evaluating C sequestration potential with the integrated model/database system. We are working closely with EPA`s Office of Policy and Program Evaluation to define a reasonable set of policy alternatives for this assessment focusing on policy that might be affected through a revised Farm Bill, such as incentives to selectively promote conservation tillage, crop rotations, and/or good stewardship of the conservation reserve. Policy alternatives are translated into basic data for use in soil C models through economic models. These data, including such elements as agricultural practices, fertilization rates, and production levels are used in the soil C models to produce net carbon changes on a per unit area basis. The unit-area emissions are combined with areal-extent data in a GIS to produce an estimate of total carbon and nitrogen changes and thus estimate greenhouse benefits.

    In this report, the damage and countermeasures taken in relation to the Great Hanshin Earthquake are described. We report on the measures taken to counter damage in affected Good Laboratory Practice (GLP) studies by citing concrete examples. Case A: the testing facility was not affected, but a regulatory inspection had been scheduled for this day. Fortunately, official inspectors had reached the facility on schedule. Case B: The building for toxicology experiments was destroyed. Fortunately, most of the GLP-compliant experiments had been completed except one, the preparation of histological samples that was the last stage of the experiment. We asked the regulatory authority for appropriate countermeasures. The answer was that an inspection of the study could be conducted if an inspection is judged to be necessary. Case C: A necropsy was scheduled on this day. The study director decided that the necropsy should be postponed at least 1 week until he could secure the number of researchers needed to conduct the necropsy. Case D: The facility in Itami was destroyed. The facility was closed and the animals were moved to Kobe. The animal facility in Kobe was not affected, but because water supply stopped for 3 days, stocked water was used. Case E: Damage to computer systems in Kinki area was reported. Numerous computers fell from desks or were damaged from the impact shock. With the exception of a few, most of the damaged computers were repaired.

The review outcomes demonstrate that there is a lack of accurately defined methods to evaluate and measure excipients' safety. Furthermore good manufacturing practice requirements for excipients are not effectively globalized.

    Good practices in eGov are being increasingly used by Local Governments being that it is considered by them as an advantage. The main goal is providing to the town hall a differentiation point and approximate their services to the citizens. For this, it is necessary to define and apply innovative strategies in order to increase the use of services by the citizens. This paper is framed in a research work and it presents a first overview of the existing good practices in eGov, taking in consideration the Portuguese’s reality. The good practices identified were distinguished with many awards and with a positive response from the target audience. The use of digital marketing strategies aims to increase their membership and coming closer the municipalities of its citizens through the dissemination of the good practices. At this moment the data collected are almost exclusively of good practice in Portugal, however some international practices were also identified. As a result of this study the community has a list of good practices that can be applied in their municipalities.

  11. Promoting Sustainable Agricultural Practices Through Remote Sensing Education and Outreach

    NASA Astrophysics Data System (ADS)

    Driese, K. L.; Sivanpillai, R.

    2007-12-01

    Ever increasing demand for food and fiber calls for farm management strategies such as effective use of chemicals and efficient water use that will maximize productivity while reducing adverse impacts on the environment. Remotely sensed data collected by satellites are a valuable resource for farmers and ranchers for gaining insights about farm and ranch productivity. While researchers in universities and agencies have made tremendous advances, technology transfer to end-users has lagged, preventing the farmers from taking advantage of this valuable resource. To overcome this barrier, the Upper Midwest Aerospace Consortium (UMAC), a NASA funded program headed by the University of North Dakota, has been working with end-users to promote the use of remote sensing technology for sustainable agricultural practices. We will highlight the UMAC activities in Wyoming aimed at promoting this technology to sugar-beet farmers in the Big Horn Basin. To assist farmers who might not have a computer at home, we provide them to local county Cooperative Extension Offices pre-loaded with relevant imagery. Our targeted outreach activities have resulted in farmers requesting and using new and old Landsat images to identify growth anomalies and trends which have enabled them to develop management zones within their croplands.

  2. Bad ethics, good ethics and the genetic engineering of animals in agriculture.

    PubMed

    Rollin, B E

    1996-03-01

    Genetic engineers have been remiss in addressing ethical and social issues emerging from this powerful new technology, a technology whose, implications for agriculture are profound. As a consequence of this failure, society has been uneasy about genetic engineering of animals and has had difficulty distinguishing between genuine and spurious ethical issues the technology occasions. Many of the most prominent concerns do not require a serious response. On the other hand, concerns about a variety of possible risks arising from genetic engineering of animals require careful consideration and dialogue with the public. Such concerns are an admixture of ethics and prudence. A purely ethical challenge, however, hitherto not addressed, is represented by problems of animal welfare that arise out of genetically engineering agricultural animals. A principle of "conservation of welfare" is suggested as a plausible moral rule to guide such genetic engineering.

  7. Knowledge for the good of the individual and society: linking philosophy, disciplinary goals, theory, and practice.

    PubMed

    McCurry, Mary K; Revell, Susan M Hunter; Roy, Sr Callista

    2010-01-01

    Nursing as a profession has a social mandate to contribute to the good of society through knowledge-based practice. Knowledge is built upon theories, and theories, together with their philosophical bases and disciplinary goals, are the guiding frameworks for practice. This article explores a philosophical perspective of nursing's social mandate, the disciplinary goals for the good of the individual and society, and one approach for translating knowledge into practice through the use of a middle-range theory. It is anticipated that the integration of the philosophical perspective and model into nursing practice will strengthen the philosophy, disciplinary goal, theory, and practice links and expand knowledge within the discipline. With the focus on humanization, we propose that nursing knowledge for social good will embrace a synthesis of the individual and the common good. This approach converges vital and agency needs described by Hamilton and the primacy of maintaining the heritage of the good within the human species as outlined by Maritain. Further, by embedding knowledge development in a changing social and health care context, nursing focuses on the goals of clinical reasoning and action. McCubbin and Patterson's Double ABCX Model of Family Adaptation was used as an example of a theory that can guide practice at the community and global level. Using the theory-practice link as a foundation, the Double ABCX model provides practising nurses with one approach to meet the needs of individuals and society. The integration of theory into nursing practice provides a guide to achieve nursing's disciplinary goals of promoting health and preventing illness across the globe. When nursing goals are directed at the synthesis of the good of the individual and society, nursing's social and moral mandate may be achieved.

  8. Ammonia Emissions from the Agriculture Sector of Argentina in a Context of Changing Technologies and Practices

    NASA Astrophysics Data System (ADS)

    Dawidowski, L. E.

    2015-12-01

    Agriculture is a key sector of the Argentinean economy, accounting for 6 to 8 5% of the GDP in the last ten years. Argentina switched in the 90´s from an articulated co-evolution between extensive livestock and crop farming, with annual rotation of crops and livestock, to intensive decoupled practices. Under these new production schemes, ecosystems were supplied with more nutrients, generating increasing levels of wastes. Other changes have also occurred, associated with the shift of the agricultural frontier and the consequent reduction in the cattle stock. In addition, changes related to climate through the strong increase in rainfall in the 80s and 90s in the west Pampas, helped to boost agricultural development. The agriculture sector accounts for practically all NH3 emissions in Argentina, however no inventory has been thus far available. To bridge this gap and particularly to have accurate input information to run coupled atmospheric chemistry models for secondary inorganic aerosols, we estimated 2000-2012 NH3 emissions, both at national and spatially disaggregated levels. Of particular interest for us was also temporal disaggregation as crops growing and temperature exhibit strong seasonal variability. As no NH3 inventory was available we also estimated related N2O emissions to verify our estimates with those of national GHG emission inventory (NEI). National NH3 emissions in 2012 amounted to 309.9 Gg, use of fertilizers accounted for 43.6%, manure management 18,9%, manure in pasture 36,0% and agricultural waste burning 1.5%. Our N2O estimates are in good agreement with the GHG-NEI. NH3 estimates in the EDGAR database for 2008 are 84.0% higher than ours for this year, and exhibit more significant differences per category, namely 113,6% higher for use of fertilizers and about 500% higher for agricultural waste burning. Urea dominates national NH3 emissions, accounting for 32,8% of the total and its use for wheat and corn crops dominates the trend.

  10. Tools to share good chairside teaching practice: a clinical scenario and appreciative questionnaire.

    PubMed

    Sweet, J; Wilson, J; Pugsley, L; Schofield, M

    2008-12-13

    This article provides a scenario for analysis of good chairside teaching practice to serve as a starting point for continued discussion in this complex field. Documented issues of good chairside teaching practice are cross-referenced to a clinical scenario with explanations in the form of a commentary. This provided the context for generating a set of questions that are provided as tools to support good chairside practice. These tools are designed to be used with 'Appreciative Inquiry', which claims that there is much to be gained by discovering where excellence is possible and elaborating upon this. Although this process can be carried out in single units or departments, it is proposed that collaboration between institutions would allow sharing of valuable innovations and greater understanding of educational training, production of good practice guidance and professional development of staff. This article is the third in a series of three and provides a scaffold for a scenario and questions to encourage collaboration in evolving and sharing good chairside teaching practice. The first article investigated the perceptions of stakeholders in chairside teaching at a single dental school and the second evaluated chairside teaching on a UK wide scale. A further accompanying article reviews some of the educational methodology and innovations in teaching and learning that may be applied to dentistry.

  11. Deforestation, agriculture and farm jobs: a good recipe for Plasmodium vivax in French Guiana

    PubMed Central

    2013-01-01

    Background In a malaria-endemic area the distribution of patients is neither constant in time nor homogeneous in space. The WHO recommends the stratification of malaria risk on a fine geographical scale. In the village of Cacao in French Guiana, the study of the spatial and temporal distribution of malaria cases, during an epidemic, allowed a better understanding of the environmental factors promoting malaria transmission. Methods A dynamic cohort of 839 persons living in 176 households (only people residing permanently in the village) was constituted between January1st, 2002 and December 31st, 2007. The information about the number of inhabitants per household, the number of confirmed cases of Plasmodium vivax and house GPS coordinates were collected to search for spatial or temporal clustering using Kurlldorff’s statistical method. Results Of the 839 persons living permanently in the village of Cacao, 359 persons presented at least one vivax malaria episode between 2002 and 2007. Five temporal clusters and four spatial clusters were identified during the study period. In all temporal clusters, April was included. Two spatial clusters were localized at the north of the village near the Comté River and two others localized close to orchards. Conclusion The spatial heterogeneity of malaria in the village may have been influenced by environmental disturbances due to local agricultural policies: deforestation, cultures of fresh produce, or drainage of water for agriculture. This study allowed generating behavioural, entomological, or environmental hypotheses that could be useful to improve prevention campaigns. PMID:23497050

    2016-03-01

    Randomized, clinical trials are commonly regarded as the highest level of evidence to support clinical decisions. Good Clinical Practice guidelines have been constructed to provide an ethical and scientific quality standard for trials that involve human subjects in a manner aligned with the Declaration of Helsinki. Originally designed to provide a unified standard of trial data to support submission to regulatory authorities, the principles may also be applied to other studies of human subjects. Although the application of Good Clinical Practice principles generally led to improvements in the quality and consistency of trial operations, these principles have also contributed to increasing trial complexity and costs. Alternatively, the growing availability of electronic health record data has facilitated the possibility for streamlined pragmatic clinical trials. The central tenets of Good Clinical Practice and pragmatic clinical trials represent potential tensions in trial design (stringent quality and highly efficient operations). In the present article, we highlight potential areas of discordance between Good Clinical Practice guidelines and the principles of pragmatic clinical trials and suggest strategies to streamline study conduct in an ethical manner to optimally perform clinical trials in the electronic age.

  11. Guide of good practices for occupational radiological protection in plutonium facilities

    SciTech Connect

    1998-06-01

    This Technical Standard (TS) does not contain any new requirements. Its purpose is to provide guides to good practice, update existing reference material, and discuss practical lessons learned relevant to the safe handling of plutonium. the technical rationale is given to allow US Department of Energy (DOE) health physicists to adapt the recommendations to similar situations throughout the DOE complex. Generally, DOE contractor health physicists will be responsible to implement radiation protection activities at DOE facilities and DOE health physicists will be responsible for oversight of those activities.

    Sport plays an important role within society and sports stadia provide significant settings for public health strategies. In addition to being places of mass gathering, stadia are often located in less affluent areas and are traditionally attended by 'harder to reach' communities. Unfortunately sports stadia and the clubs they host are rarely perceived as places that promote healthy lifestyles. Fast food, alcohol and tobacco are commonly advertized, served and consumed during sports games giving the spectators and TV fans contradictory messages concerning healthy choices. As part of a wider programme of work part-funded by the European Union, a study was therefore designed to explore current 'good practice' relating to positive health interventions in sports stadia across a number of European countries. Using a specially designed questionnaire, information about health policies and good practices relating to food offerings in stadia, physical activity promotion among local communities, tobacco policy, positive mental health initiatives, environmental sustainability practices and social responsibility policies were collected in 10 European countries (England and Northern Ireland, Finland, Georgia, Greece, Ireland, Italy, Latvia, Poland, Spain and Sweden) involving 88 stadia. The audit results show that stadia health policies differ considerably between specific countries and sports. Based on the literature analysed, the examples of good practices collected through the study, and the subsequent instigation of a European Healthy Stadia Network, it shows that there is considerable potential for stadia to become health promoting settings.

    This updated Good Publication Practice (GPP) guideline, known as GPP3, builds on earlier versions and provides recommendations for individuals and organizations that contribute to the publication of research results sponsored or supported by pharmaceutical, medical device, diagnostics, and biotechnology companies. The recommendations are designed to help individuals and organizations maintain ethical and transparent publication practices and comply with legal and regulatory requirements. These recommendations cover publications in peer-reviewed journals and presentations (oral or poster) at scientific congresses. The International Society for Medical Publication Professionals invited more than 3000 professionals worldwide to apply for a position on the steering committee, or as a reviewer, for this guideline. The GPP2 authors reviewed all applications (n = 241) and assembled an 18-member steering committee that represented 7 countries and a diversity of publication professions and institutions. From the 174 selected reviewers, 94 sent comments on the second draft, which steering committee members incorporated after discussion and consensus. The resulting guideline includes new sections (Principles of Good Publication Practice for Company-Sponsored Medical Research, Data Sharing, Studies That Should Be Published, and Plagiarism), expands guidance on the International Committee of Medical Journal Editors' authorship criteria and common authorship issues, improves clarity on appropriate author payment and reimbursement, and expands information on the role of medical writers. By following good publication practices (including GPP3), individuals and organizations will show integrity; accountability; and responsibility for accurate, complete, and transparent reporting in their publications and presentations.

    Previous studies examining the associations between sleep hygiene practices and insomnia have produced inconsistent results. This study further investigates this issue by examining different domains of sleep hygiene separately. One hundred and six insomnia patients and 89 good sleepers participated in the study. Their sleep hygiene, sleep quality and insomnia severity were assessed with subjective rating scales. Among good sleepers, almost all domains of sleep hygiene correlated significantly with their sleep ratings. However, in insomnia patients, only the arousal-related behavior correlated with sleep ratings. The findings suggest that strategies in prevention and treatment of sleep disturbance may be different accordingly.

  1. Integrating seasonal climate prediction and agricultural models for insights into agricultural practice

    2005-01-01

    Interest in integrating crop simulation models with dynamic seasonal climate forecast models is expanding in response to a perceived opportunity to add value to seasonal climate forecasts for agriculture. Integrated modelling may help to address some obstacles to effective agricultural use of climate information. First, modelling can address the mismatch between farmers' needs and available operational forecasts. Probabilistic crop yield forecasts are directly relevant to farmers' livelihood decisions and, at a different scale, to early warning and market applications. Second, credible ex ante evidence of livelihood benefits, using integrated climate–crop–economic modelling in a value-of-information framework, may assist in the challenge of obtaining institutional, financial and political support; and inform targeting for greatest benefit. Third, integrated modelling can reduce the risk and learning time associated with adaptation and adoption, and related uncertainty on the part of advisors and advocates. It can provide insights to advisors, and enhance site-specific interpretation of recommendations when driven by spatial data. Model-based ‘discussion support systems’ contribute to learning and farmer–researcher dialogue. Integrated climate–crop modelling may play a genuine, but limited role in efforts to support climate risk management in agriculture, but only if they are used appropriately, with understanding of their capabilities and limitations, and with cautious evaluation of model predictions and of the insights that arises from model-based decision analysis.

    Background Good clinical practice (GCP) guidelines have been the source of improvement in the quality of clinical trials; however, there are limitations to the application of GCP in the conduct of health research beyond industry-sponsored clinical trials. The UNICEF/UNDP/World Bank/WHO Special Program for Research and Training in Tropical Disease is promoting good practice in all health research involving human through the Good Health Research Practice (GHRP) training program initiative. Objective To report the results of piloting the GHRP training program and formulate further steps to harness GHRP for promoting good practices in all health research involving human, particularly in low- and middle-income countries (LMICs). Design The objective of this training is to impart knowledge and skills for the application of ethical and quality principles to the design, conduct, recording, and reporting of health research involving human participants based on the level of risk, to ensure a fit-for-purpose quality system. This has been formulated into five sequential modules to be delivered in a 4-day course. Four courses have been organized in the pilot phase (2014-2015). The courses have been evaluated and assessed based on course feedback (quantitative and qualitative data) collected during course implementation and qualitative email-based pre- and post-course evaluation. Results Participants were highly satisfied with the course content and its organization. The relevance and applicability of the course content resulted in positive feedback and an articulated willingness to adapt and disseminate the course. Action points to strengthen the training program have been identified, and showed the imminent need to develop a consensus with a broader range of key stakeholders on the final set of GHRP standards and means for implementation.

    Carroll, Erica Eggers

    Good laboratory practice standards are US federal regulations enacted as part of the Federal Insecticide, Fungicide, and Rodenticide Act (40 CFR Part 160), the Toxic Substance Control Act (40 CFR Part 792), and the Good Laboratory Practice for Nonclinical Laboratory Studies (21 CFR Part 58) to support protection of public health in the areas of pesticides, chemicals, and drug investigations in response to allegations of inaccurate data acquisition. Essentially, good laboratory practices (GLPs) are a system of management controls for nonclinical research studies involving animals to ensure the uniformity, consistency, reliability, reproducibility, quality, and integrity of data collected as part of chemical (including pharmaceuticals) tests, from in vitro through acute to chronic toxicity tests. The GLPs were established in the United States in 1978 as a result of the Industrial Bio-Test Laboratory scandal which led to congressional hearings and actions to prevent fraudulent data reporting and collection. Although the establishment of infrastructure for GLPs compliance is labor-intensive and time-consuming, achievement and maintenance of GLP compliance ensures the accuracy of the data collected from each study, which is critical for defending results, advancing science, and protecting human and animal health. This article describes how and why those in the US Army Medical Department responsible for protecting the public health of US Army and other military personnel made the policy decision to have its toxicology laboratory achieve complete compliance with GLP standards, the first such among US Army laboratories. The challenges faced and how they were overcome are detailed.

    An experiment was carried out under plastic house conditions to compare the effect of four fermented organic matter sources (cattle, poultry and sheep manure in addition to 1:1:1 mixture of the three organic matter sources) in which 4 kg organic matter m(-2) were used, with that of the conventional agriculture (chemical fertilizers) treatments on Marvello red pepper fruit quality, by using a Randomized Complete Block Design (RCBD) with four replicates. Pepper fruits characteristics cultivated in soil supplemented with manure were generally better than those from plants grown in soil only. Addition of animal manure increased bell pepper fruit content of soluble solids, ascorbic acid, total phenols, crude fibre and intensity of red color as compare with conventional agriculture that produced fruits with higher titratable acidity, water content, lycopene and bigger fruit size. In most cases of animal manure treatments, best results were obtained by the sheep manure treatment that produced the highest TSS, while the worst results were obtained by the poultry manure treatment that produced the smallest fruit and lowest fruit lycopene content.

    The introduction of sustainable practices is considered a win-win strategy for low-income countries because of its potential to simultaneously improve food security and address environmental issues. Despite the numerous studies that focus on the adoption of technological innovations, little work has been done on the socio-psychological behaviour of farmers with regard to sustainable practices. This study investigates smallholder farmers' intentions towards two practices: minimum tillage and row planting. The decomposed theory of planned behaviour is used as a theoretical framework to analyse the intentions. The findings reveal that attitudes and normative issues positively explain farmers' intentions to adopt both practices. Perceived control also has a positive significant effect on the intention to apply minimum tillage. When the intention is formed, farmers are expected to carry out their intention when opportunities arise. Moreover, perceived usefulness, social capital, and perceived ease of operation are also significant predictors of farmers' attitudes. Furthermore, social capital and training are factors that positively affect the normative issue, which in turn also positively mediates the relationship between training, social capital and intention. Finally, it is shown that neither the perceived resources nor information from the media significantly affect farmers' intentions. This paper thus confirms that social capital, personal efficacy, training and perceived usefulness play significant roles in the decision to adopt sustainable practices. In addition, willingness to adopt seems to be limited by negative attitudes and by weak normative issues. Therefore, to improve adoption of sustainable practices by smallholder farmers, attention should be given to socio-psychological issues. This could lead to improvements in farm productivity and enhance the livelihoods of smallholders.

    This study aimed to explore the current practice of performing high ear-piercing regarding consent protocols, and methods of practice using questionnaire-based survey in Hertfordshire and North London. Recommendations for good clinical practice are also made. 100 establishments performing ear piercing were identified. A 16-item questionnaire on techniques used, methods of high-ear piercing, methods of sterilization, consent issues and aftercare was completed. Seventy-six establishments agreed to participate. All practitioners prepared the skin before piercing. 58 (76%) used a needle for piercing, 11 (15%) used a spring-loaded gun and seven (9%) used both. 97% of the practitioners obtained written consent before proceeding. 9 (12%) had a lower age limit of 16 years and three (4%) of 18 years. 27 piercers (36%) provided an aftercare leaflet, 41 (54%) warned the patients about risks of infection, 16 (21%) warned about cosmetic deformity and 1 (1%) specifically mentioned cauliflower ear. Results indicated that high ear piercing is an invasive procedure with a significant risk of complications leading to cosmetic deformity. Establishments should be required to counsel patients properly about the risks and potential complications of the procedure. A code of practice should be drawn up with a minimum age for piercing, requirement for proper consent, excellent hygiene and good information for postoperative care.

    Quantifying soil organic carbon (SOC) dynamics at a high spatial and temporal resolution in response to different agricultural management practices and environmental conditions can help identify practices that both sequester carbon in the soil and sustain agricultural productivity. Using an agricultural systems model (the Agricultural Production Systems sIMulator), we conducted a high spatial resolution and long-term (122 years) simulation study to identify the key management practices and environmental variables influencing SOC dynamics in a continuous wheat cropping system in Australia's 96 million ha cereal-growing regions. Agricultural practices included five nitrogen application rates (0-200 kg N ha(-1) in 50 kg N ha(-1) increments), five residue removal rates (0-100% in 25% increments), and five residue incorporation rates (0-100% in 25% increments). We found that the change in SOC during the 122-year simulation was influenced by the management practices of residue removal (linearly negative) and fertilization (nonlinearly positive) - and the environmental variables of initial SOC content (linearly negative) and temperature (nonlinearly negative). The effects of fertilization were strongest at rates up to 50 kg N ha(-1) , and the effects of temperature were strongest where mean annual temperatures exceeded 19 °C. Reducing residue removal and increasing fertilization increased SOC in most areas except Queensland where high rates of SOC decomposition caused by high temperature and soil moisture negated these benefits. Management practices were particularly effective in increasing SOC in south-west Western Australia - an area with low initial SOC. The results can help target agricultural management practices for increasing SOC in the context of local environmental conditions, enabling farmers to contribute to climate change mitigation and sustaining agricultural production.

    Agriculture is a dominant evolutionary force that drives the evolution of both domesticated and wild species. However, the various mechanisms of agriculture-induced evolution and their socio-ecological consequences are not often synthetically discussed. Here, we explore how agricultural practices and evolutionary changes in domesticated species cause evolution in wild species. We do so by examining three processes by which agriculture drives evolution. First, differences in the traits of domesticated species, compared with their wild ancestors, alter the selective environment and create opportunities for wild species to specialize. Second, selection caused by agricultural practices, including both those meant to maximize productivity and those meant to control pest species, can lead to pest adaptation. Third, agriculture can cause non-selective changes in patterns of gene flow in wild species. We review evidence for these processes and then discuss their ecological and sociological impacts. We finish by identifying important knowledge gaps and future directions related to the eco-evolutionary impacts of agriculture including their extent, how to prevent the detrimental evolution of wild species, and finally, how to use evolution to minimize the ecological impacts of agriculture.This article is part of the themed issue 'Human influences on evolution, and the ecological and societal consequences'.

    Because of the major international-level events that have recently been held in Brazil, concerns about the sensory and hygienic-sanitary conditions of food have increased. The objective of this study was to evaluate the implementation of good handling practices in food and beverage areas of hotels, with and without outsourced professional intervention. We evaluated 19 food and beverage areas in hotels in Porto Alegre, Rio do Sul, Brazil, using a checklist that was developed by a municipal surveillance team based on existing laws for good handling practices. The evaluation was done by a skilled professional in the food safety area on two occasions, at the beginning of the study (January to May 2013) and at the end (July to November 2014), and the establishments were classified as good, regular, or poor. After the baseline evaluation, an action plan listing the noncompliance found at each location was given to those responsible for the establishments, and a period of 1 year 6 months was stipulated for improvements to be made. In the repeat evaluation, those responsible for the establishments were asked whether they had hired an outsourced professional to assist them in the improvements. The hotels showed improvement during the repeat evaluation, but a significant increase in the percentage of overall adequacy was seen only in the food and beverages areas of the 12 hotels that used the intervention of an outsourced professional. The better percentage of adequacy in establishments with outsourced professional intervention underlines the importance of an external and impartial view of routine activities in the implementation of good handling practices.

    The technique of electroencephalographic neurofeedback (EEG NF) emerged in the 1970s and is a technique that measures a subject's EEG signal, processes it in real time, extracts a parameter of interest and presents this information in visual or auditory form. The goal is to effectuate a behavioural modification by modulating brain activity. The EEG NF opens new therapeutic possibilities in the fields of psychiatry and neurology. However, the development of EEG NF in clinical practice requires (i) a good level of evidence of therapeutic efficacy of this technique, (ii) a good practice guide for this technique. Firstly, this article investigates selected trials with the following criteria: study design with controlled, randomized, and open or blind protocol, primary endpoint related to the mental and brain disorders treated and assessed with standardized measurement tools, identifiable EEG neurophysiological targets, underpinned by pathophysiological relevance. Trials were found for: epilepsies, migraine, stroke, chronic insomnia, attentional-deficit/hyperactivity disorder (ADHD), autism spectrum disorder, major depressive disorder, anxiety disorders, addictive disorders, psychotic disorders. Secondly, this article investigates the principles of neurofeedback therapy in line with learning theory. Different underlying therapeutic models are presented didactically between two continua: a continuum between implicit and explicit learning and a continuum between the biomedical model (centred on "the disease") and integrative biopsychosocial model of health (centred on "the illness"). The main relevant learning model is to link neurofeedback therapy with the field of cognitive remediation techniques. The methodological specificity of neurofeedback is to be guided by biologically relevant neurophysiological parameters. Guidelines for good clinical practice of EEG NF concerning technical issues of electrophysiology and of learning are suggested. These require validation by

    This manual consists of six sections: Properties of Plutonium, Siting of Plutonium Facilities, Facility Design, Radiation Protection, Emergency Preparedness, and Decontamination and Decommissioning. While not the final authority, the manual is an assemblage of information, rules of thumb, regulations, and good practices to assist those who are intimately involved in plutonium operations. An in-depth understanding of the nuclear, physical, chemical, and biological properties of plutonium is important in establishing a viable radiation protection and control program at a plutonium facility. These properties of plutonium provide the basis and perspective necessary for appreciating the quality of control needed in handling and processing the material. Guidance in selecting the location of a new plutonium facility may not be directly useful to most readers. However, it provides a perspective for the development and implementation of the environmental surveillance program and the in-plant controls required to ensure that the facility is and remains a good neighbor. The criteria, guidance, and good practices for the design of a plutonium facility are also applicable to the operation and modification of existing facilities. The design activity provides many opportunities for implementation of features to promote more effective protection and control. The application of ''as low as reasonably achievable'' (ALARA) principles and optimization analyses are generally most cost-effective during the design phase. 335 refs., 8 figs., 20 tabs.

    Using peer learning strategies, seven experienced PBRNs working in collaborative teams articulated procedures for PBRN Research Good Practices (PRGPs). The PRGPs is a PBRN-specific resource to facilitate PBRN management and staff training, to promote adherence to study protocols, and to increase validity and generalizability of study findings. This paper describes the team science processes which culminated in the PRGPs. Skilled facilitators used team science strategies and methods from the Technology of Participation (ToP®), and the Consensus Workshop Method to support teams to codify diverse research expertise in practice-based research. The participatory nature of "sense-making" moved through identifiable stages. Lessons learned include (1) team input into the scope of the final outcome proved vital to project relevance; (2) PBRNs with diverse domains of research expertise contributed broad knowledge on each topic; and (3) ToP® structured facilitation techniques were critical for establishing trust and clarifying the "sense-making" process.

    For the safety of patient care, a team-based approach has been advocated as an effective measure. In clinical physiology examination, we have been making efforts to promote good practice for patient safety based on such an approach in Tokai University Hospital, as represented by quality practice in ultrasonographic examination. The entire process of ultrasonographic examination can be divided into three parts: pre-examination, examination, and post-examination processes. In each process of the examination, specific quality issues must be considered, eventually ensuring the quality and safety of patient care. A laboratory physician is responsible for not only quality assurance of examination, diagnosis, and reporting, but also patient safety. A laboratory physician can play a key role in all aspects of patient safety related to each process of the examination by taking a leadership role in the team-based approach.

    Landsat data contain features that can be interpreted to produce information about crops, in support of crop estimation procedures. This paper considers ways in which detailed knowledge of agricultural practices and events might increase and improve the utilization of Landsat data in both the predictive and observational or measurement components of such procedures. Landsat observables related to agricultural practices and events throughout the cropping season are listed. Agricultural fields are identified as the preferred observational units for incorporating refined agricultural understanding, such as crop rotation patterns, into machine procedures. Uses of Landsat data from both prior seasons and the current season are considered, as is use of predictive models of crop appearance. The investigation of knowledge engineering systems tailored to through-the-season estimation problems is recommended for long range development.

    2013-01-01

    This article explores whether the bioethical performance and trustworthiness of pharmaceutical companies can be improved by harnessing market forces through the use of accreditation, certification, or rating. Other industries have used such systems to define best practices, set standards, and assess and signal the quality of services, processes, and products. These systems have also informed decisions in other industries about where to invest, what to buy, where to work, and when to regulate. Similarly, accreditation, certification, and rating programs can help drug companies address stakeholder concerns in four areas: clinical trial design and management, dissemination of clinical trial results, marketing practices, and the accessibility of medicines. To illuminate processes - such as conflicts of interests and revolving-door policies - that can jeopardize the integrity of accreditation, certification, and ratings systems, the article concludes with a consideration of recent failures of credit-rating agencies and a review of the regulatory capture literature.

    This paper comprises a selection tool for water disinfection methods for fresh produce pre- and postharvest practices. A variety of water disinfection technologies is available on the market and no single technology is the best choice for all applications. It can be difficult for end users to choose the technology that is best fit for a specific application. Therefore, the different technologies were characterized in order to identify criteria that influence the suitability of a technology for pre- or postharvest applications. Introduced criteria were divided into three principal components: (i) criteria related to the technology and which relate to the disinfection efficiency, (ii) attention points for the management and proper operation, and (iii) necessities in order to sustain the operation with respect to the environment. The selection criteria may help the end user of the water disinfection technology to obtain a systematic insight into all relevant aspects to be considered for preliminary decision making on which technologies should be put to feasibility testing for water disinfection in pre- and postharvest practices of the fresh produce chain.

    Although the principles and the necessity for good laboratory practice (GLP) guidelines to confirm the credibility, integrity, and quality of non-clinical laboratory studies have been known for more than a decade, culture collection activities are not subject to them. Because of recent advances in biotechnology, culture collections face increased demands not only for quality cultures but also current information. When applied in culture collections, GLP guidelines prove to be an excellent management tool as well as a cost-effective system of providing authentic and reliable microbial and cell cultures and associated data.

  13. Ergonomic risks and musculoskeletal disorders in production agriculture: recommendations for effective research to practice.

    PubMed

    Kirkhorn, Steven R; Earle-Richardson, Giulia; Banks, R J

    2010-07-01

    Musculoskeletal disorders (MSDs) are increasingly recognized as a significant hazard of agricultural occupation. In agricultural jobs with significant physical labor, MSDs are typically the most frequently reported injury. Although not as lethal as tractor roll-overs, MSDs can result in disability, lost work time, and increased production costs. MSDs increase production costs as a result of worker absence, medical and insurance costs, decreased work capacity, and loss of employees to turnover and competition from other less physically demanding industries. This paper will provide an overview of what is currently known about MSDs in agriculture, including high-risk commodities, tasks and work practices, and the related regulatory factors and workers' compensation costs. As agricultural production practices evolve, the types of MSDs also change, as do ergonomic risk factors. One example is the previous higher rates of knee and hip arthritis identified in farmers in stanchion dairies evolving into upper extremity tendonitis, arthritis, and carpal tunnel syndrome now found in milking technicians in dairy milking parlors. This paper summarizes the presentation, "Musculoskeletal Disorders in Labor-Intensive Operations," at the Agricultural Safety and Health Council of America/National Institute for Occupational Safety and Health conference, "Be Safe, Be Profitable: Protecting Workers in Agriculture," January 27-28, 2010, Dallas/Fort Worth, Texas. The primary focus of the paper is to address current research on ergonomic solutions for MSDs in agriculture. These include improved tools, carts or equipment, as well as work practices. One of the key challenges in this area pertains to measurement, due to the fact that musculoskeletal strain is a chronic condition that can come and go, with self-reported pain as its only indicator. Alternative measurement methods will be discussed. Finally, the implementation of research into practice is reviewed, with an emphasis on best

    The first guidance on Good Cell Culture Practice (GCCP) dates back to 2005. This document expands this to include aspects of quality assurance for in vitro cell culture focusing on the increasingly diverse cell types and culture formats used in research, product development, testing and manufacture of biotechnology products and cell-based medicines. It provides a set of basic principles of best practice that can be used in training new personnel, reviewing and improving local procedures, and helping to assure standard practices and conditions for the comparison of data between laboratories and experimentation performed at different times. This includes recommendations for the documentation and reporting of culture conditions. It is intended as guidance to facilitate the generation of reliable data from cell culture systems, and is not intended to conflict with local or higher level legislation or regulatory requirements. It may not be possible to meet all recommendations in this guidance for practical, legal or other reasons. However, when it is necessary to divert from the principles of GCCP, the risk of decreasing the quality of work and the safety of laboratory staff should be addressed and any conclusions or alternative approaches justified. This workshop report is considered a first step toward a revised GCCP 2.0.

    The aim of this study was to gain insight into potential differences in risk factors for microbial contamination in greenhouse versus open field lettuce production. Information was collected on sources, testing, and monitoring and if applicable, treatment of irrigation and harvest rinsing water. These data were combined with results of analysis on the levels of Escherichia coli as a fecal indicator organism and the presence of enteric bacterial pathogens on both lettuce crops and environmental samples. Enterohemorragic Escherichia coli (EHEC) PCR signals (vt1 or vt2 positive and eae positive), Campylobacter spp., and Salmonella spp. isolates were more often obtained from irrigation water sampled from open field farms (21/45, 46.7%) versus from greenhouse production (9/75, 12.0%). The open field production was shown to be more prone to fecal contamination as the number of lettuce samples and irrigation water with elevated E. coli was significantly higher. Farmers comply with generic guidelines on good agricultural practices available at the national level, but monitoring of microbial quality, and if applicable appropriateness of water treatment, or water used for irrigation or at harvest is restricted. These results indicate the need for further elaboration of specific guidelines and control measures for leafy greens with regard to microbial hazards. PMID:25546272

  18. Practicing Conservation Agriculture to mitigate and adapt to Climate Change in Jordan.

    2016-04-01

    Climate change scenarios indicate that Jordan and the Middle East could suffer from reduced agricultural productivity and water availability among other negative impacts. Based on the projection models for the area, average temperature in Jordan is projected to increase between 1.2 and 1.6 °C by 2050. Projections for precipitation trends are projected to decrease by 16% by the year 2050. Evaporation is likely to increase due to higher temperatures. This is likely to increase the incidence of drought potential since precipitation is projected to decrease. The dominant form of agriculture system in Jordan is based on intensive tillage. This form of tillage has resulted in large losses of organic soil carbon, weaker soil structure, and cause compaction. It has negative effects on soil aeration, root development and water infiltration among other factors. There is a need to transform farming practices to conservation agriculture to sequester carbon so that climate change mitigation becomes an inherent property of future farming systems. Conservation Agriculture, a system avoiding or minimizing soil disturbance, combined with soil cover and crop diversification, is considered to be a sustainable production system that can also sequester carbon unlike tillage agriculture. Conservation agriculture promotes minimal disturbance of the soil by tillage (zero tillage), balanced application of chemical inputs and careful management of residues and wastes. This study was conducted to develop a clear understanding of the impacts and benefits of the two most common types of agriculture, traditional tillage agriculture and conservation agriculture with respect to their effects on land productivity and on soil carbon pools. The study results indicated that conservation agriculture contributed to the reduction of the farming systems' greenhouse gas emissions and enhance its role as carbon sinks. Also, it was found that by shifting to conservation agriculture labor cost needed for

    2006-01-01

    Recent advances in health risk reduction approaches are examined based on inter-country networking experiences. A noteworthy progress is the wider application of low-cost improvements to risk reduction particularly in small enterprises and agriculture in both industrially developing and developed countries. This is helped by the readiness of managers and workers to implement these improvements despite many constraints. Typical improvements include mobile racks, simple workstation changes, screening hazards, better welfare facilities and teamwork arrangements. In view of the complex circumstances of work-related health risks, it is important to know whether a low-cost strategy can advance risk reduction practices effectively and what support measures are necessary. It is confirmed that the strategy can overcome related constraints through its advantages. Main advantages lie in (a) the facilitation of improved practices in multiple technical areas, (b) the strengthening of realistic stepwise risk reduction, and (c) the enhanced multiplier effects through training of local trainers. Action-oriented risk assessment tools, such as action checklists and low-cost improvement guides, can encourage risk-reducing measures adjusted to each local situation. It is suggested to spread the low-cost risk reduction strategy for improving small workplaces in diversified settings with the support of these locally tailored tools.

  1. Environmental monitoring programs vs Good Laboratory Practice (GLP) programs: differences and similarities.

    PubMed

    Bentley, R E

    1995-12-01

    Environmental monitoring and Good Laboratory Practice programs are similar when looked at empirically. Both address quality issues, human or environmental safety, and have set procedures to assure the concomitant results. However, when compared at the operational level, they can be best described as very different. Good Laboratory Practice programs deal basically with two governmental agencies and their divisions- the Environmental Protection Agency and Food and Drug Administration. These are administered from the federal level involving no state resources. These programs are objective driven with the procedures being defined in study plans, protocols, and standard operating procedures. The environmental monitoring testing programs deal with a profusion of federal legislation including CERCLA (also known as CLP), RCRA, CWA, CAA, SDWA, NPDES and others. These acts require analysis by specific procedures mandated by the statutes. States operate many of these programs and have been given the authority by the federal government. Many of the states require separate certifications to conduct these analyses. Environmental monitoring testing laboratories often must acquire multiple state certifications to participate in multiple state programs. This is not cost effective and often leads to conflicting requirements. Much of the direction for having a national certification program comes from problems associated with these state-operated programs.

    The claim for cell culture to provide validable in vitro models for biomedical research postulates evasion of possible fatal record keeping errors. A prototype of a relational computer database for IBM-compatible personal computers using Microsoft(r) Windows 95/98/2000 and NT for administration of cell culture data has been developed using Microsoft(r) Access 98 (Microsoft Corporation, Redmond, USA), -Access Basic, -Visual Basic and Structured Query Language (SQL) (IBM Corporation, Armonk, USA), and was tested successfully. The modular software application manages the many aspects of cell culture laboratory record keeping like detailed information on tissue donor, primary cell isolation/cell line origin, immunohistochemical/molecular biological characterisation, cell countings at passaging/subcultivation/cell aliquotation and cryopreservation. One main feature is a collection of all methods performed at our cell culture laboratory, where linked tables and files store specific informations. Entries into the database are checked via validation rules for correctness to avoid mistakes. The developed prototype has been demonstrated to be an adaptable, reliable tool for improving quality of information storage according to Good Scientific Practice (GSP), Good Cell Culture Practice (GCCP) and general ISO certification trends.

  3. Good laboratory practices for biochemical genetic testing and newborn screening for inherited metabolic disorders.

    PubMed

    2012-04-06

    Biochemical genetic testing and newborn screening are essential laboratory services for the screening, detection, diagnosis, and monitoring of inborn errors of metabolism or inherited metabolic disorders. Under the Clinical Laboratory Improvement Amendments of 1988 (CLIA) regulations, laboratory testing is categorized on the basis of the level of testing complexity as either waived (i.e., from routine regulatory oversight) or nonwaived testing (which includes tests of moderate and high complexity). Laboratories that perform biochemical genetic testing are required by CLIA regulations to meet the general quality systems requirements for nonwaived testing and the personnel requirements for high-complexity testing. Laboratories that perform public health newborn screening are subject to the same CLIA regulations and applicable state requirements. As the number of inherited metabolic diseases that are included in state-based newborn screening programs continues to increase, ensuring the quality of performance and delivery of testing services remains a continuous challenge not only for public health laboratories and other newborn screening facilities but also for biochemical genetic testing laboratories. To help ensure the quality of laboratory testing, CDC collaborated with the Centers for Medicare & Medicaid Services, the Food and Drug Administration, the Health Resources and Services Administration, and the National Institutes of Health to develop guidelines for laboratories to meet CLIA requirements and apply additional quality assurance measures for these areas of genetic testing. This report provides recommendations for good laboratory practices that were developed based on recommendations from the Clinical Laboratory Improvement Advisory Committee, with additional input from the Secretary's Advisory Committee on Genetics, Health, and Society; the Secretary's Advisory Committee on Heritable Disorders in Newborns and Children; and representatives of newborn

    In order to support agribusiness and to attain food security for ever-increasing populations, most countries in the world have embraced modern agricultural technologies. Ecological consequences of the technocentric approaches, and their sustainability and impacts on human health have, however, not received adequate attention particularly in developing countries. India is one country that has undergone a rapid transformation in the field of agriculture by adopting strategies of the Green Revolution. This article provides a comparative analysis of the effects of older and newer paradigms of agricultural practices on ecosystem and human health within the larger context of sustainability. The study was conducted in three closely situated areas where different agricultural practices were followed: (a) the head-end of a modern canal-irrigated area, (b) an adjacent dryland, and (c) an area (the ancient area) that has been provided with irrigation for some 800 years. Data were collected by in-depth interviews of individual farmers, focus-group discussions, participatory observations, and from secondary sources. The dryland, receiving limited rainfall, continues to practice diverse cropping centered to a large extent on traditional coarse cereals and uses only small amounts of chemical inputs. On the other hand, modern agriculture in the head-end emphasizes continuous cropping of rice supported by extensive and indiscriminate use of agrochemicals. Market forces have, to a significant degree, influenced the ancient area to abandon much of its early practices of organic farming and to take up aspects of modern agricultural practice. Rice cultivation in the irrigated parts has changed the local landscape and vegetation and has augmented the mosquito population, which is a potential vector for malaria, Japanese encephalitis and other diseases. Nevertheless, despite these problems, perceptions of adverse environmental effects are lowest in the heavily irrigated area.

    2010-12-01

    The objective of this study is to investigate the effects of climate change and agricultural management practices on suspended sediment concentrations in the Potlach River basin in northwestern Idaho. Suspended sediment is a pollutant in many water systems and contributes to the impairment of streams. Conventional tillage practices and rain-on-snow events in the Palouse region of northern Idaho and eastern Washington can produce some of the highest sediment losses per acre in the United States. Climate change may lead to further problems as more frequent and intense winter storm events are predicted to occur. Many hydrological models have been developed which examine suspended sediment in river systems. The Potlatch River basin near Julietta, ID was examined using the Distributed Hydrology Soil Vegetation Model (DHSVM), which has a sediment module that includes surface erosion and channel sediment transport. DHSVM was calibrated and evaluated over the historical period of streamflow observations and was used to predict soil erosion rates and suspended sediment concentrations using a range of downscaled Global Climate Models (GCMs) emissions scenarios for the year 2045. Furthermore, the sensitivity of suspended sediment concentrations to conventional versus convservative tillage practices was explored. The results show that as the projected climate-driven intensity of storms increase, more sediment is predicted in the Potlatch River. Suspended sediment and streamflow are predicted to increase during the late fall through the early spring. This increase occurs during times of heightened runoff when suspended sediment concentration in the river is highest. Three tillage scenarios were incorporated into DHSVM for winter wheat: conventional till, reduced till, and no till. Erosion and suspended sediment were higher during storm events under conventional agricultural tillage scenarios. In the long-term, this research can lead to examination of the effects of climate

    The use of antibiotics in agriculture is considered a contributing factor to the problem of antibiotic resistance. A majority of antibiotics and related drugs produced in the United States are not used to treat the infirm, but rather are used as feed additives for agricultural animals to promote growth and compensate for stressful and crowded growing conditions. Significant efforts must be made to decrease inappropriate overuse in animals and agriculture. Several leading health and political organizations have begun to address the issue. The American Nurses Association has established policies that call on Congress, the U.S. Food and Drug Administration, and meat producers to promptly phase out the agricultural practices that promote antibiotic resistance.

    Practice guidelines, although important in promoting quality, can also be harmful if they do not advocate the best options for patients. The latter can occur because of uncertainties in scientific evidence, biases in guideline development, and patient heterogeneity. Guidelines must therefore accurately describe the quality of the evidence and the degree of uncertainty that underlie recommendations. Proper methods for developing practice guidelines are reviewed.

    Different agricultural practices may have substantial impacts on crop physiology and yield. However, it is still not entirely clear how multiple agricultural practices such as tillage, biochar and different nutrient applications could influence corn physiology and yield. We conducted a three-year field experiment to study the responses of corn physiology, yield, and soil respiration to six different agricultural practices. The six treatments included conventional tillage (CT) or no tillage (NT), in combination with nitrogen type (URAN or chicken litter) and application method, biochar, or denitrification inhibitor. A randomized complete block design was applied with six replications. Leaf photosynthetic rate, transpiration, plant height, leaf area index (LAI), biomass, and yield were measured. Results showed that different agricultural practices had significant effects on plant leaf photosynthesis, transpiration, soil respiration, height, and yield, but not on LAI and biomass. The average corn yield in the NT-URAN was 10.03 ton/ha, 28.9% more than in the CT-URAN. Compared to the NT-URAN, the NT-biochar had lower soil respiration and similar yield. All variables measured showed remarkable variations among the three years. Our results indicated that no tillage treatment substantially increased corn yield, probably due to the preservation of soil moisture during drought periods. PMID:27272142

    Different agricultural practices may have substantial impacts on crop physiology and yield. However, it is still not entirely clear how multiple agricultural practices such as tillage, biochar and different nutrient applications could influence corn physiology and yield. We conducted a three-year field experiment to study the responses of corn physiology, yield, and soil respiration to six different agricultural practices. The six treatments included conventional tillage (CT) or no tillage (NT), in combination with nitrogen type (URAN or chicken litter) and application method, biochar, or denitrification inhibitor.

    Practice-based research networks (PBRNs) can function as a platform for delivery of patient-centered care consistent with the Patient Protection and Affordable Care Act. Patient-centered (centric) clinical studies encourage the patient to be an integral part of study design and outcome. The patient's electronic health record contributes to the shared national health care data set. PBRNs integrate health care data in real time at the point of care and reflect the full context of the person's health. PBRNs designed under the principles of good clinical practice (GCP) validate studies related to comparative effectiveness research and drug development. PBRNs can generate large amounts of data from known patient histories so that side effects can be assessed in their totality. The larger and more diverse number of patients recruited suggests that point-of-care-data, where both provider and patient participate in the treatment, may be more robust in that side effects, drug-drug interactions and number of concomitant medications used may be identified earlier in the development process. The GCP PBRN concept affords continuous patient information for both care and research purposes. These all contribute to an ethical approach for the pharmaceutical industry to generate clinical research data for regulatory submission and to contribute to a HIPAA-compliant national database that could contribute to improved health care delivery and pharmacovigilance.

  15. Medical Gas Containers and Closures; Current Good Manufacturing Practice Requirements. Final rule.

    PubMed

    2016-11-18

    The Food and Drug Administration (FDA or the Agency) is amending its current good manufacturing practice (CGMP) and labeling regulations regarding medical gases. FDA is requiring that portable cryogenic medical gas containers not manufactured with permanent gas use outlet connections have gas-specific use outlet connections that cannot be readily removed or replaced except by the manufacturer. FDA is also requiring that portable cryogenic medical gas containers and high-pressure medical gas cylinders meet certain labeling, naming, and color requirements. These requirements are intended to increase the likelihood that the contents of medical gas containers are accurately identified and reduce the likelihood of the wrong gas being connected to a gas supply system or container. FDA is also revising an existing regulation that conditionally exempts certain medical gases from certain otherwise-applicable labeling requirements in order to add oxygen and nitrogen to the list of gases subject to the exemption, and to remove cyclopropane and ethylene from the list.

  16. The good, the bad and the ugly: the practical consequences of centrosome amplification.

    Centrosome amplification (the presence of more than two centrosomes at mitosis) is characteristic of many human cancers. Extra centrosomes can cause the assembly of multipolar spindles, which unequally distribute chromosomes to daughter cells; the resulting genetic imbalances may contribute to cellular transformation. However, this raises the question of how a population of cells with centrosome amplification can survive such chaotic mitoses without soon becoming non-viable as a result of chromosome loss. Recent observations indicate that a variety of mechanisms partially mute the practical consequences of centrosome amplification. Consequently, populations of cells propagate with good efficiency, despite centrosome amplification, yet have an elevated mitotic error rate that can fuel the evolution of the transformed state.

    Therapist adherence describes the quality of interventions according to the imperatives of a treatment model. We examined the relationship between therapist adherence and symptom change in the context of a short-term treatment with respect good psychiatric management (GPM) principles. Based on a parent trial, borderline personality disorder patients (N = 40) benefited from a 10-session intervention. Adherence to GPM was assessed using a GPM Adherence Scale (GPMAS). The psychometric properties of the GPMAS were excellent, and the adherence to GPM explained 16% of the general symptom improvement (t(1) = 2.38, β = 0.40, p = 0.02) and 23% of the borderline symptom improvement (t(1) = 2.46, β = 0.48, p = 0.02). Because GPM adherence predicts the outcome after only 10 sessions, GPMAS is a valuable measure early on in psychiatric practice as part of an initial step to longer-term treatment, to quickly detect problems and correct them.

    Computational fluid dynamics (CFD) modelling in the wastewater treatment (WWT) field is continuing to grow and be used to solve increasingly complex problems. However, the future of CFD models and their value to the wastewater field are a function of their proper application and knowledge of their limits. As has been established for other types of wastewater modelling (i.e. biokinetic models), it is timely to define a good modelling practice (GMP) for wastewater CFD applications. An International Water Association (IWA) working group has been formed to investigate a variety of issues and challenges related to CFD modelling in water and WWT. This paper summarizes the recommendations for GMP of the IWA working group on CFD. The paper provides an overview of GMP and, though it is written for the wastewater application, is based on general CFD procedures. A forthcoming companion paper to provide specific details on modelling of individual wastewater components forms the next step of the working group.

    Good Clinical Practice (GCP) is an international ethical and scientific quality standard for the design, conduct, performance, monitoring, auditing, recording, analyses and reporting of clinical trials. It also serves to protect the rights, integrity and confidentiality of trial subjects. It is very important to understand the background of the formation of the ICH-GCP guidelines as this, in itself, explains the reasons and the need for doing so. In this paper, we address the historical background and the events that led up to the formation of these guidelines. Today, the ICH-GCP guidelines are used in clinical trials throughout the globe with the main aim of protecting and preserving human rights. PMID:21614316

    Protein sequence comparison methods have grown increasingly sensitive during the last decade and can often identify distantly related proteins sharing a common ancestor some 3 billion years ago. Although cellular function is not conserved so long, molecular functions and structures of protein domains often are. In combination with a domain-centered approach to function and structure prediction, modern remote homology detection methods have a great and largely underexploited potential for elucidating protein functions and evolution. Advances during the last few years include nonlinear scoring functions combining various sequence features, the use of sequence context information, and powerful new software packages. Since progress depends on realistically assessing new and existing methods and published benchmarks are often hard to compare, we propose 10 rules of good-practice benchmarking.

The Handbook incorporates editorial changes to DOE-STD-1061-93, ``Guide to Good Practices for the Selection, Training, and Qualification of shift Supervisors,`` and supersedes DOE-STD-1061-93. Technical content of this Handbook has not changed from the original technical standard. Changes are primarily editorial improvements, redesignation of the standard to a Handbook, and format changes to conform with current Technical Standards Program procedures. This guide, used in conjunction with a facility-specific job analysis, provides a framework for the selection, training, qualification, and professional development of reactor facility and non-reactor nuclear facility shift supervisors. Training and qualification programs based on this guide should provide assurance that shift supervisors perform their jobs safely and competently.

    How can the Environmental Protection Agency's Good Laboratory Practice (GLP) regulations, originally written primarily for mammalian toxicology studies, be applied to regulatory studies conducted for genetically modified plants? Do they fit? Can they be applied and still make sense? How is a Quality Assurance Unit (QAU) to interpret the requirements in this new area of biotechnology? The answers to these questions are discussed in this brief presentation of how one team within the Monsanto QAU, along with the researchers, developed am effective and comprehensive compliance program by applying the "traditional approach" to the GLP regulations to a new and important scientific field in regulatory compliance. Topics discussed will address the differences in the approach between traditional toxicity testing and the newer technology and how the differences were resolved, new and innovative definitions of particular phases and other aspects of regulatory studies, and how the draft regulations for pesticidal plants will help this area of technology in the future.

As automated data collection systems have become more common in toxicology facilities, the U.S. Food and Drug Administration and the U.S. Environmental Protection Agency have begun to focus inspections in this area. This historical review documents the development of regulatory guidance on computer validation in toxicology over the past several decades. An overview of the components of a computer life cycle is presented, including the development of systems descriptions, validation plans, validation testing, system maintenance, SOPs, change control, security considerations, and system retirement. Examples are provided for implementation of computer validation principles on laboratory computer systems in a toxicology facility.

    The Italian inspecting system for compliance with the good laboratory practice (GLP) principles is fully operative since late 1996. Over these past years documents have been issued and specific guidelines have been worked out to properly perform the activities prescribed. This preparatory work has allowed the Italian system to harmonize with those of the other member states of the European Union. In the frame of other international activities, the Italian Inspectorate has participated in the mutual joint visits programme set up by OECD. Much effort has been invested to pinpoint differences in the approaches followed by the various Italian inspecting teams when inspecting test facilities. From this standpoint, the priority was the attainment of reliable information as well as of solutions that would allow the harmonization of the conduct of GLP inspections. It cannot be overlooked, in fact, that there are 24 inspectors, to whom a substantial number of experts has to be added.

    We have established a current good manufacturing practice (GMP) manufacturing process to produce a nanoparticle suspension of 1,1'-methylenebis-4-[(hydroxyimino)methyl]pyridinium dimethanesulfonate (MMB4 DMS) in cottonseed oil (CSO) as a nerve agent antidote for a Phase 1 clinical trial. Bis-pyridinium oximes such as MMB4 were previously developed for emergency treatment of organophosphate nerve agent intoxication. Many of these compounds offer efficacy superior to monopyridinium oximes, but they have poor thermal stability due to hydrolytic cleavage in aqueous solution. We previously developed a nonaqueous nanoparticle suspension to improve the hydrothermal stability, termed Enhanced Formulation (EF). An example of this formulation technology is a suspension of MMB4 DMS nanoparticles in CSO. Due to the profound effect of particle size distribution on product quality and performance, particle size must be controlled during the manufacturing process. Therefore, a particle size analysis method for MMB4 DMS in CSO was developed and validated to use in support of good laboratory practice/GMP development and production activities. Manufacturing of EF was accomplished by milling MMB4 DMS with CSO and zirconia beads in an agitator bead mill. The resulting bulk material was filled into 5-mL glass vials at a sterile fill facility and terminally sterilized by gamma irradiation. The clinical lot was tested and released, a Certificate of Analysis was issued, and a 3-year International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use (ICH) stability study started. The drug product was placed in storage for Phase 1 clinical trial distribution. A dose delivery uniformity study was undertaken to ensure that the correct doses were delivered to the patients in the clinic.

    Relations between riverine export (load) of total nitrogen (N) and total phosphorus (P) from 133 large agricultural watersheds in the United States and factors affecting nutrient transport were evaluated using empirical regression models. After controlling for anthropogenic inputs and other landscape factors affecting nutrient transport-such as runoff, precipitation, slope, number of reservoirs, irrigated area, and area with subsurface tile drains-the relations between export and the area in the Conservation Reserve Program (CRP) (N) and conservation tillage (P) were positive. Additional interaction terms indicated that the relations between export and the area in conservation tillage (N) and the CRP (P) progressed from being clearly positive when soil erodibility was low or moderate, to being close to zero when soil erodibility was higher, to possibly being slightly negative only at the 90th to 95th percentile of soil erodibility values. Possible explanations for the increase in nutrient export with increased area in management practices include greater transport of soluble nutrients from areas in conservation tillage; lagged response of stream quality to implementation of management practices because of nitrogen transport in groundwater, time for vegetative cover to mature, and/or prior accumulation of P in soils; or limitations in the management practice and stream monitoring data sets. If lags are occurring, current nutrient export from agricultural watersheds may still be reflecting the influence of agricultural land-use practices that were in place before the implementation of these management practices.

    Good Clinical Practice (GCP) is an international standard for the design, conduct, performance, monitoring, auditing, recording, analyses, and reporting of clinical trials. The goal of GCP is to ensure the protection of the rights, integrity, and confidentiality of clinical trial participants and to ensure the credibility and accuracy of data and reported results. In the United States, trial sponsors generally require investigators to complete GCP training prior to participating in each clinical trial to foster GCP and as a method to meet regulatory expectations (ie, sponsor's responsibility to select qualified investigators per 21 CFR 312.50 and 312.53(a) for drugs and biologics and 21 CFR 812.40 and 812.43(a) for medical devices). This training requirement is often extended to investigative site staff, as deemed relevant by the sponsor, institution, or investigator. Those who participate in multiple clinical trials are often required by sponsors to complete repeated GCP training, which is unnecessarily burdensome. The Clinical Trials Transformation Initiative convened a multidisciplinary project team involving partners from academia, industry, other researchers and research staff, and government to develop recommendations for streamlining current GCP training practices. Recommendations drafted by the project team, including the minimum key training elements, frequency, format, and evidence of training completion, were presented to a broad group of experts to foster discussion of the current issues and to seek consensus on proposed solutions.

    Decision-analytic models (DAMs) used to evaluate the cost effectiveness of interventions are pivotal sources of evidence used in economic evaluations. Parameter estimates used in the DAMs are often based on the results of a regression analysis, but there is little guidance relating to these. This study had two objectives. The first was to identify the frequency of use of regression models in economic evaluations, the parameters they inform, and the amount of information reported to describe and support the analyses. The second objective was to provide guidance to improve practice in this area, based on the review. The review concentrated on a random sample of economic evaluations submitted to the UK National Institute for Health and Clinical Excellence (NICE) as part of its technology appraisal process. Based on these findings, recommendations for good practice were drafted, together with a checklist for critiquing reporting standards in this area. Based on the results of this review, statistical regression models are in widespread use in DAMs used to support economic evaluations, yet reporting of basic information, such as the sample size used and measures of uncertainty, is limited. Recommendations were formed about how reporting standards could be improved to better meet the needs of decision makers. These recommendations are summarised in a checklist, which may be used by both those conducting regression analyses and those critiquing them, to identify what should be reported when using the results of a regression analysis within a DAM.

    Good cell culture practice and characterization of the cell lines used are of critical importance in in vitro genotoxicity testing. The objective of this initiative was to make continuously available stocks of the characterized isolates of the most frequently used mammalian cell lines in genotoxicity testing anywhere in the world ('IVGT' cell lines). This project was organized under the auspices of the International Life Sciences Institute (ILSI) Health and Environmental Sciences Institute (HESI) Project Committee on the Relevance and Follow-up of Positive Results in In Vitro Genetic Toxicity (IVGT) Testing. First, cell isolates were identified that are as close as possible to the isolate described in the initial publications reporting their use in genotoxicity testing. The depositors of these cell lines managed their characterization and their expansion for preparing continuously available stocks of these cells that are stored at the European Collection of Cell Cultures (ECACC, UK) and the Japanese Collection of Research Bioresources (JCRB, Japan). This publication describes how the four 'IVGT' cell lines, i.e. L5178Y TK(+/-) 3.7.2C, TK6, CHO-WBL and CHL/IU, were prepared for deposit at the ECACC and JCRB cell banks. Recommendations for handling these cell lines and monitoring their characteristics are also described. The growth characteristics of these cell lines (growth rates and cell cycles), their identity (karyotypes and genetic status) and ranges of background frequencies of select endpoints are also reported to help in the routine practice of genotoxicity testing using these cell lines.

    New economic, environmental and social challenges for the mining industry in the USA show the need to implement "responsible" mining practices that include improved community involvement. Conflicts which occur in the US territory and with US mining companies around the world are now common between the mining proponents, NGO's and communities. These conflicts can sometimes be alleviated by early development of modes of communication, and a formal discussion format that allows airing of concerns and potential resolution of problems. One of the methods that can formalize this process is to establish a Good Neighbor Agreement (GNA), which deals specifically with challenges in relationships between mining operations and the local communities. It is a new practice related to mining operations that are oriented toward social needs and concerns of local communities that arise during the normal life of a mine, which can achieve sustainable mining practices. The GNA project being currently developed at the University of Nevada, USA in cooperation with the Newmont Mining Corporation has a goal of creating an open company/community dialog that will help identify and address sociological and environmental concerns associated with mining. Discussion: The Good Neighbor Agreement currently evolving will address the following: 1. Identify spheres of possible cooperation between mining companies, government organizations, and NGO's. 2. Provide an economically viable mechanism for developing a partnership between mining operations and the local communities that will increase mining industry's accountability and provide higher levels of confidence for the community that a mine is operated in a safe and sustainable manner. Implementation of the GNA can help identify and evaluate conflict criteria in mining/community relationships; determine the status of concerns; determine the role and responsibilities of stakeholders; analyze problem resolution feasibility; maintain the community

    On April 27th 2011, the French Supreme Administrative Court (Conseil d'État) granted the Recommendations for Good Practice set out by the French National Authority for Health (Haute Autorité de santé--[HAS]) a legal status, considering that they "must be regarded as (…) decisions which may be subject to an action for annulment". The judge came to this conclusion through a quasi-syllogistic reasoning. Firstly, the French Code of Medical Ethics requires physicians to care for their patients in accordance with established scientific knowledge. Secondly, the HAS recommendations recall in particular this established scientific knowledge. Treating patients according to established scientific knowledge requires then that physicians follow the HAS recommendations. While the case at bar does not directly involve liability for medical malpractice-since the applicant only sought to have an HAS recommendation declared void-it is nonetheless necessary to examine the impact of this ruling for health professionals. Indeed, this decision raises a number of concerns for everyday medical practice. Guidelines concerning the endocrine treatment of hormonodependant breast cancers are plentiful. In January 2010, the HAS and the French National Institute for Cancer (Institut national du cancer) issued a "Guide for long-term illnesses-Breast cancer" (Guide ALD - Cancer du sein). In addition to these nation-wide guidelines, the Regional Networks for Cancer (réseaux régionaux de cancérologie) issued their own recommendations. Other guidelines are also set out in the framework of consensus conferences, such as the Nice Saint-Paul-de-Vence (France) and St. Gallen (Switzerland) conferences. In the United States, the National Comprehensive Cancer Network (NCCN) and the American Society of Clinical Oncology (ASCO), and in Europe, the European Society of Medical Oncology (ESMO) make recommendations as well. Therefore, the HAS recommendations are hardly the sole source of information for

    Agriculture is a backbone for many African economies, with an estimated 70% of Africans active in agricultural production. The sector often does not only directly contribute to, but sustains food security and poverty reduction efforts. Sustaining this productivity poses many challenges, particularly to small scale subsistence farmers (SSF) in dry land areas and semi-arid countries like Namibia. SSF in northern central Namibia mix crop and livestock production on degraded semi-arid lands and nutrient-poor sandy soils. They are fully dependent on agricultural production with limited alternative sources of income. Mostly, their agricultural harvests and outputs are low, not meeting their livelihood needs. At the same time, the land use is often not sustainable, leading to degradation. The Namibia case reveals that addressing underlying economic, social and environmental challenges requires a combination of farm level-soil management practices with a shift towards integrated landscape management. This forms the basis for SSF to adopt sustainable land management practices while building institutional foundations, like establishing SSF cooperatives. One way in which this has been tested is through the concept of incentive-based motivation, i.e. payment for ecosystem services (PES), in which some of the beneficiaries pay, for instance for farmers or land users, who provide the services. The farmers provide these services by substituting their unsustainable land and soil management and adopting new (climate smart agricultural) land use practices. Climate Smart Agricultural land use practices (CSA-LUP) are one way of providing ecosystem services, which could be fundamental to long-term sustainable soil and land management solutions in Africa. There are few PES cases which have been systematically studied from an institutional development structure perspective. This study presents lessons evolving from the notion that direct participation and involvement of local people

    Despite the large body of research in irrigated agriculture, it is still not clear which practices most effectively reduce nitrate leaching (NL) while maintaining crop yield. A meta-analysis (MA) of published experimental results from agricultural irrigated systems was conducted to identify those agricultural practices that have proven effective at reducing NL and to quantify the scale of reduction that can be achieved. Forty-four scientific articles were identified which investigated four main strategies (water and fertilizer management, use of cover crops and fertilizer technology) creating a database with 279 observations on NL and 166 on crop yield. Management practices that adjust water application to crop needs reduced NL by a mean of 80% without a reduction in crop yield. Improved fertilizer management reduced NL by 40%, and the best relationship between yield and NL was obtained when applying the recommended N fertilizer rate. Applications above the recommended rate increased leaching without enhancing yield. Replacing a fallow with a non-legume cover crop (CC) reduced NL by 50% while using a legume CC did not have any effect on NL. Legume CC increased yield and N use efficiency while yields following non-legume CC were not different from the fallow. Improved fertilizer technology also decreased NL but was the least effective of the selected strategies. The risk of nitrate leaching from irrigated systems is high, but optimum management practices may mitigate this risk and maintain crop yields while enhancing environmental sustainability.

    In order to enhance food production, India has adopted modern agriculture practices and achieved noteworthy success. This achievement was essentially the result of a paradigm shift in agriculture that included high inputs of agrochemicals, water, and widespread practice of monoculture, as well as bureaucratic changes that promoted these changes. There are very few comprehensive analyses of potential adverse health outcomes that may be related to these changes. The objective of this study is to identify health risks associated with modern agricultural practices in the southern Indian state of Karnataka. This study aims to compare high-input and low-input agricultural practices and the consequences for health of people in these communities. The fieldwork was conducted from May to August, 2009 and included a survey carried out in six villages. Data were collected by in-depth personal interviews among 240 households and key informants, field observations, laboratory analyses, and data from secondary sources. The study identified four major visible impacts: occupational hazards, vector borne diseases, changing nutritional status, and inequity in development. In the high-input area, mechanization has resulted in more occurrences of serious accidents and injuries. Ecological changes due to rice cultivation in this area have further augmented mosquito breeding, and there has been a surge in the incidence of Japanese encephalitis and malaria. The traditional coarse cereals (complex carbohydrates, high protein) have been replaced by mill-polished rice (simple carbohydrate, low protein). The prevalence of overweight (BMI>25) has emerged as a new public health challenge, and this is most evident in large-landholding households, especially in the high-input agriculture areas. In all agro-ecological areas, it was observed that women faced a greater risk of both extremes of under-nutrition and being overweight. Output-driven and market-oriented modern agricultural practices have

    Over the last decades rainfall has become more intense in Sicily, making large proportions of steeply sloping agricultural land more vulnerable to soil erosion, mainly orchards and vineyards (Diodato and Bellocchi 2010). The prevention of soil degradation is indirectly addressed in the European Union's Water Framework Directive (2000/60/EC) and Sustainable Use Directive (2009/128/EC). As a consequence, new EU compliance conditions for food producers requires them to have tools and solutions for on-farm implementation of sustainable practices (Singh et al. 2014). The Agricultural Runoff and Best Management Practice Tool has been developed by Syngenta to help farm advisers and managers diagnose the runoff potential from fields with visible signs of soil erosion. The tool consists of 4 steps including the assessment of three key landscape factors (slope, topsoil permeability and depth to restrictive horizon) and 9 mainly soil and crop management factors influencing the runoff potential. Based on the runoff potential score (ranging from 0 to 10), which is linked to a runoff potential class, the Runoff Tool uses in-field and edge-of-the-field Best Management Practices (BMPs) to mitigate runoff (aligned with advice from ECPA's TOPPS-prowadis project). The Runoff tool needs testing in different regions and crops to create a number of use scenarios with regional/crop specific advice on BMPs. For this purpose the Tool has been tested in vineyards of the Tasca d'Almerita and Planeta wineries, which are large family-owned estates with long-standing tradition in viticulture in Sicily. In addition to runoff potential scores, Visual Soil Assessment (VSA) scores have been calculated to allow for a comparison between different diagnostic tools. VSA allows for immediate diagnosis of soil quality (a higher score means a better soil quality) including many indicators of runoff (Shepherd 2008). Runoff potentials were moderate to high in all tested fields. Slopes were classified as

    Studies of human reverse cholesterol transport require intravenous infusion of cholesterol tracers. Because insoluble lipids may pose risk and because it is desirable to have consistent doses of defined composition available over many months, we investigated the manufacture of cholesterol tracer under current good manufacturing practice (CGMP) conditions appropriate for phase 1 investigation. Cholesterol tracer was prepared by sterile admixture of unlabeled cholesterol or cholesterol-d7 in ethanol with 20% Intralipid®. The resulting material was filtered through a 1.2 micron particulate filter, stored at 4°C, and tested at time 0, 1.5, 3, 6, and 9 months for sterility, pyrogenicity, autoxidation, and particle size and aggregation. The limiting factor for stability was a rise in thiobarbituric acid-reacting substances of 9.6-fold over 9 months (P < 0.01). The emulsion was stable with the Z-average intensity-weighted mean droplet diameter remaining at 60 nm over 23 months. The zeta potential (a measure of negative surface charge protecting from aggregation) was unchanged at −36.2. Rapid cholesterol pool size was 25.3 ± 1.3 g. Intravenous cholesterol tracer was stable at 4°C for 9 months postproduction. CGMP manufacturing methods can be achieved in the academic setting and need to be considered for critical components of future metabolic studies. PMID:26416797

    Prior to human clinical trials, nonclinical safety and toxicology studies are required to demonstrate that a new product appears safe for human testing; these nonclinical studies are governed by good laboratory practice (GLP) regulations. As academic health centers (AHCs) embrace the charge to increase the translation of basic science research into clinical discoveries, researchers at these institutions increasingly will be conducting GLP-regulated nonclinical studies. Because the consequences for noncompliance are severe and many AHC researchers are unfamiliar with Food and Drug Administration regulations, the authors describe the regulatory requirements for conducting GLP research, including the strict documentation requirements, the necessary personnel training, the importance of study monitoring, and the critical role that compliance oversight plays in the process. They then explain the process that AHCs interested in conducting GLP studies should take before the start of their research program, including conducting a needs assessment and a gap analysis and selecting a model for GLP compliance. Finally, the authors identify and analyze several critical barriers to developing and implementing a GLP-compliant infrastructure at an AHC. Despite these challenges, the capacity to perform such research will help AHCs to build and maintain competitive research programs and to facilitate the successful translation of faculty-initiated research from nonclinical studies to first-in-human clinical trials.

    ABSTRACT Objectives: To describe indicators and processes developed and implemented for pharmaceutical assistance at the Einstein Program at Paraisópolis Community pharmacy. Methods: This was a descriptive study of retrospective data from January 2012 to December 2015. Data were obtained from spreadsheets developed for monitoring the productivity and care quality provided at the pharmacy. The evaluated variables were pharmaceutical assistance to prescription, pharmaceutical intervention, orientation (standard and pharmaceutical) and pharmaceutical orientation rate. Results: The pharmacy assisted, on average, 2,308 prescriptions monthly, dispensing 4,871 items, including medications, materials and food supplements. Since March 2015, virtually, the pharmacist analyzed all prescriptions, prior to dispensing. In the analyzed period, there was an increase in monthly pharmaceutical interventions from 7 to 32 on average, and, although there was a decrease in the number of standard orientation, the pharmaceutical orientation had an increase, causing a rise of pharmaceutical orientation rate from 4 to 11%. Conclusion: The processes developed and implemented at the program pharmacy sought to follow the good pharmacy practice, and help patients to make the best use of their medications. PMID:27759833

  6. Making abortions safe: a matter of good public health policy and practice.

    2000-01-01

    Globally, abortion mortality accounts for at least 13% of all maternal mortality. Unsafe abortion procedures, untrained abortion providers, restrictive abortion laws and high mortality and morbidity from abortion tend to occur together. Preventing mortality and morbidity from abortion in countries where these remain high is a matter of good public health policy and medical practice, and constitutes an important part of safe motherhood initiatives. This article examines the changes in policy and health service provision required to make abortions safe. It is based on a wide-ranging review of published and unpublished sources. In order to be effective, public health measures must take into account the reasons why women have abortions, the kind of abortion services required and at what stages of pregnancy, the types of abortion service providers needed, and training, cost and counselling issues. The transition from unsafe to safe abortions demands the following: changes at national policy level; abortion training for service providers and the provision of services at the appropriate primary level health service delivery points; and ensuring that women access these services instead of those of untrained providers. Public awareness that abortion services are available is a crucial element of this transition, particularly among adolescent and single women, who tend to have less access to reproductive health services generally.

    Randomized clinical trials are commonly regarded as the highest level of evidence to support clinical decisions. Good Clinical Practice (GCP) guidelines have been constructed to provide an ethical and scientific quality standard for trials that involve human subjects in a manner aligned with the Declaration of Helsinki. Originally designed to provide a unified standard of trial data to support submission to regulatory authorities, the principles may also be applied to other studies of human subjects. While the application of GCP principles generally led to improvements in the quality and consistency of trial operations, these principles have also contributed to increasing trial complexity and costs. Alternatively, growing availability of electronic health record data has facilitated the possibility for streamlined pragmatic clinical trials (PCTs). The central tenets of GCP and PCTs represent potential tensions in trial design (stringent quality and highly efficient operations). In the present manuscript, we highlight potential areas of discordance between GCP guidelines and the principles of PCTs and suggest strategies to streamline study conduct in an ethical manner to optimally carry out clinical trials in the electronic age.

    The DOE Guide to Good Practices For The Selection, Training, and Qualification of Shift Technical Advisors can be used by any DOE nuclear facility that has implemented the shift technical advisor position. DOE Order 5480-20, ``Personnel Selection, Qualification, Training, and Staffing Requirements at DOE Reactor and Non-Reactor Nuclear Facilities,`` states that only Category A reactors must use shift technical advisor position. However, many DOE nuclear facilities have implemented the shift technical advisor position to provide independent on-shift technical advice and counsel to the shift operating personnel to help determine cause and mitigation of facility accidents. Those DOE nuclear facilities that have implemented or are going to implement the shift technical advisor position will find this guide useful. This guide addresses areas that may be covered by other training programs. In these cases, it is unnecessary (and undesirable) to duplicate these areas in the STA training program as long as the specific skills and knowledge essential for STAs are addressed. The guide is presented based on the premise that the trainee has not completed any facility-specific training other than general employee training.

    OECD has been involved in the harmonisation of policies and instruments for chemicals control since the late 1970's. The OECD principles of good laboratory practice (GLP) were developed and subsequently adopted by the Council in 1981. These principles have the primary objective of ensuring the generation of high quality test data. They set out managerial concepts covering the organisation of test laboratories as well as the conditions under which laboratory studies are planned, performed, monitored, recorded and reported. A system of compliance monitoring procedures has been established to ensure that laboratory studies are carried out in member countries according to the principles of GLP. The harmonization and mutual recognition of compliance monitoring methods among member countries have been a crucial step in ensuring the international acceptability of data. This undertaking involved the development of consistent criteria for determining whether a laboratory conducts studies in accordance with the principles of GLP. Training courses are held for GLP inspectors, an activity which lies at the basis of harmonising monitoring procedures. Consensus workshops result in consensus documents on the harmonised application and interpretation of the GLP principles in specific areas or on specific points. This system makes it possible for countries to speak the same language when exchanging information about specific laboratories, and to have confidence in the quality and rigour of safety tests undertaken in a laboratory.

    The Dietary Supplement Health and Education Act (DSHEA) was enacted in October 1994 to promote the health of Americans by ensuring easier access to safe dietary supplements. Many supplements such as vitamins, minerals, herbs and amino acids have been reported to be helpful in chronic conditions (i.e., heart disease, cancer and osteoporosis). Under DSHEA, dietary supplements can be marketed without prior FDA approval; the burden is on this agency to show that a marketed dietary supplement is unsafe. However, DSHEA retained the FDA's authority to issue regulations that require the manufacture of dietary supplements be in compliance with current good manufacturing practice (cGMP) standards, which are needed to ensure their quality. Several quality-related concerns of marketed dietary supplements that came to light since the passage of DSHEA prompted the FDA in 2003 to propose rules for cGMP for the manufacture, packaging and holding (storage) of dietary supplements. This review will present the highlights of these proposed rules, focusing on the legislative history of DSHEA, rationale for proposing cGMPs along with a general discussion of the specific requirements. Given the voluminous nature of the specific details, the reader is directed to the pertinent FDA publications for details. In this analysis, selected scientific and legal issues are also discussed to promote a better understanding and implications of these rules.

    Crop yields are sensitive to both agricultural practice and climate changes. Under different agricultural practice scenarios, crop yield may have different climate sensitivities. Since it is important to understand how future climate changes affect agriculture productivity and what the potential adaptation strategies would be to compensate for possible negative impacts on crop production, we performed experiments to study climate sensitivity under different agricultural practice scenarios for rice, maize and wheat in the top four production provinces in China using the Decision Support System for Agrotechnology Transfer (DSSAT) crop model. The agricultural practice scenarios include four categories: different amounts of nitrogen fertilizer or no nitrogen stress; irrigation turned on or off, or no water stress; all possible seeds in the DSSAT cultivar data base; and different planting dates. For the climate sensitivity test, the control climate is from 1998 to 2007, and we individually modify four climate variables: daily maximum and minimum temperature by +2 °C and -2 °C, daily precipitation by +20% and -20%, and daily solar radiation by + 20% and -20%. With more nitrogen fertilizer applied, crops are more sensitive to temperature changes as well as precipitation changes because of their release from nitrogen limitation. With irrigation turned on, crop yield sensitivity to temperature decreases in most of the regions depending on the amount of the local precipitation, since more water is available and soil temperature varies less with higher soil moisture. Those results indicate that there could be possible agriculture adaptation strategies under certain future climate scenarios. For example, increasing nitrogen fertilizer usage by a certain amount might compensate for the negative impact on crop yield from climate changes. However, since crops are more sensitive to climate changes when there is more nitrogen fertilizer applied, if the climate changes are

    The purpose of this study was to identify what motivates employers to promote good occupational health and safety practices in small-scale enterprises. Previous studies have shown that small-scale enterprises generally pay insufficient attention to issues of occupational health and safety. These findings were mainly derived from questionnaire based surveys. Nevertheless, some small-scale enterprises in which employers exercise good leadership do take a progressive approach to occupational health and safety. Although good practices can be identified in small-scale enterprises, it remains unclear what motivates employers in small-scale enterprises to actively implement occupational health and safety practices. We speculated that identifying employer motivations in promoting occupational health would help to spread good practices among small-scale enterprises. Using a qualitative approach based on the KJ methods, we interviewed ten employers who actively promote occupational health and safety in the workplace. The employers were asked to discuss their views of occupational health and safety in their own words. A semi-structured interview format was used, and transcripts were made of the interviews. Each transcript was independently coded by two or more researchers. These transcripts and codes were integrated and then the research group members discussed the heading titles and structural relationships between them according to the KJ method. Qualitative analysis revealed that all the employers expressed a strong interest in a "good company" and "good management". They emphasized four elements of "good management", namely "securing human resources", "trust of business partners", "social responsibility" and "employer's health condition itself", and considered that addressing occupational health and safety was essential to the achievement of these four elements. Consistent with previous findings, the results showed that implementation of occupational health and safety

    Over the last decades, an increasing number of studies have been conducted to assess the effect of soil management practices on soil organic carbon (SOC) stocks. At regional scales, biogeochemical models such as CENTURY or Roth-C have been commonly applied. These models simulate SOC dynamics at the profile level (point basis) over long temporal scales but do not consider the continuous lateral transfer of sediment that takes place along geomorphic toposequences. As a consequence, the impact of soil redistribution on carbon fluxes is very seldom taken into account when evaluating changes in SOC stocks due to agricultural management practices on the short and long-term. To address this gap, we assessed the role of soil erosion by water and tillage on SOC stocks under different agricultural management practices in the Walloon region of Belgium. The SPEROS-C model was run for a 100-year period combining three typical crop rotations (using winter wheat, winter barley, sugar beet and maize) with three tillage scenarios (conventional tillage, reduced tillage and reduced tillage in combination with additional crop residues). The results showed that including soil erosion by water in the simulations led to a general decrease in SOC stocks relative to a baseline scenario (where no erosion took place). The SOC lost from these arable soils was mainly exported to adjacent sites and to the river system by lateral fluxes, with magnitudes differing between crop rotations and in all cases lower under conservation tillage practices than under conventional tillage. Although tillage erosion plays an important role in carbon redistribution within fields, lateral fluxes induced by water erosion led to a higher spatial and in-depth heterogeneity of SOC stocks with potential effects on the soil water holding capacity and crop yields. This indicates that studies assessing the effect of agricultural management practices on SOC stocks and other soil properties over the landscape should

    Symbiotic associations between arbuscular mycorrhizal fungi (AMF) and plant roots are widespread in natural environments and provide a range of benefits to the host plant. These include improved nutrition, enhanced resistance to soil-borne pests, diseases, and drought, as well as tolerance to heavy metals. In addition, the presence of a well developed AMF hyphal network improve the soil structure. As obligate mutualistic symbionts these fungi colonize the roots of many agricultural crops and it is often claimed that agricultural practices (use of fertilizers and biocides, tillage, dominance of monocultures and the growing of non-mycorrhizal crops) are detrimental to AMF. As a result, agro ecosystems impoverished in AMF may not get the fully expected range of benefits from these fungi. Using molecular markers on DNA extracted directly from soil and roots we studied the effects of different management practices (tillage and nitrogen fertilization) on the AMF populations colonizing an experimental agro ecosystem in Central Italy. Fungi in roots and soil were identified by cloning and sequencing a region of ~550bp of the 18S rDNA and ~600bp of the 28S rDNA. In symbiosis with the maize roots we detected only members of Glomeraceae group A that showed decrement in number under nitrogen fertilization. Instead in soil were mainly present members of two AMF groups, respectively Gigasporaceae and Glomeraceae group A. In addition only the low input management practices preserve also members of Diversisporaceae and Glomeraceae group B. From our study we can conclude that agricultural practices can directly or indirectly influence AMF biodiversity. The result of this study highlight the importance and significant effects of the long term nitrogen fertilization and tillage practices on specific groups of fungi playing a key role in arable soils.

    Background While attention has been paid to physical risks in the work environment and the promotion of individual employee health, mental health protection and promotion have received much less focus. Psychosocial risk management has not yet been fully incorporated in such efforts. This paper presents good practices in promoting mental health in the workplace in line with World Health Organization (WHO) guidance by identifying barriers, opportunities, and the way forward in this area. Methods Semistructured interviews were conducted with 17 experts who were selected on the basis of their knowledge and expertise in relation to good practice identified tools. Interviewees were asked to evaluate the approaches on the basis of the WHO model for healthy workplaces. Results The examples of good practice for Workplace Mental Health Promotion (WMHP) are in line with the principles and the five keys of the WHO model. They support the third objective of the WHO comprehensive mental health action plan 2013–2020 for multisectoral implementation of WMHP strategies. Examples of good practice include the engagement of all stakeholders and representatives, science-driven practice, dissemination of good practice, continual improvement, and evaluation. Actions to inform policies/legislation, promote education on psychosocial risks, and provide better evidence were suggested for higher WMHP success. Conclusion The study identified commonalities in good practice approaches in different countries and stressed the importance of a strong policy and enforcement framework as well as organizational responsibility for WMHP. For progress to be achieved in this area, a holistic and multidisciplinary approach was unanimously suggested as a way to successful implementation. PMID:26929841

    Abstract Vesicular stomatitis virus (VSV) is an oncolytic virus currently being investigated as a promising tool to treat cancer because of its ability to selectively replicate in cancer cells. To enhance the oncolytic property of the nonpathologic laboratory strain of VSV, we generated a recombinant vector [rVSV(MΔ51)-M3] expressing murine gammaherpesvirus M3, a secreted viral chemokine-binding protein that binds to a broad range of mammalian chemokines with high affinity. As previously reported, when rVSV(MΔ51)-M3 was used in an orthotopic model of hepatocellular carcinoma (HCC) in rats, it suppressed inflammatory cell migration to the virus-infected tumor site, which allowed for enhanced intratumoral virus replication leading to increased tumor necrosis and substantially prolonged survival. These encouraging results led to the development of this vector for clinical translation in patients with HCC. However, a scalable current Good Manufacturing Practice (cGMP)-compliant manufacturing process has not been described for this vector. To produce the quantities of high-titer virus required for clinical trials, a process that is amenable to GMP manufacturing and scale-up was developed. We describe here a large-scale (50-liter) vector production process capable of achieving crude titers on the order of 109 plaque-forming units (PFU)/ml under cGMP. This process was used to generate a master virus seed stock and a clinical lot of the clinical trial agent under cGMP with an infectious viral titer of approximately 2 × 1010 PFU/ml (total yield, 1 × 1013 PFU). The lot has passed all U.S. Food and Drug Administration-mandated release testing and will be used in a phase 1 clinical translational trial in patients with advanced HCC. PMID:21083425

    Abstract Background  Advocacy has a critical role to play in addressing concerns about access to appropriate mental health care and treatment for African and Caribbean men. Aim  To investigate good practice principles and organizational models for mental health advocacy provision for African and Caribbean men. Study design  The study consisted of: (i) A systematic literature review. Bibliographic and internet searching was undertaken from 1994 to 2006. The inclusion criteria related to mental health, advocacy provision for African and Caribbean men. (ii) Four focus groups with African and Caribbean men to explore needs for and experiences of mental health advocacy. (iii) An investigation into current advocacy provision through a survey of advocacy provision in England, Wales and Northern Ireland. (iv) Twenty‐two qualitative stakeholder interviews to investigate the operation of mental health advocacy for this client group. The study was undertaken in partnership with two service user‐led organizations and an African Caribbean mental health service. Results  Primary research in this area is scant. Mainstream mental health advocacy services are often poor at providing appropriate services. Services developed by the Black Community and voluntary sector are grounded in different conceptualizations of advocacy and sharper understanding of the needs of African and Caribbean men. The lack of sustainable funding for these organizations is a major barrier to the development of high‐quality advocacy for this group, reflecting a lack of understanding about their distinctive role. Conclusions  The commissioning and provision of mental health advocacy needs to recognize the distinct experiences of African and Caribbean men and develop capacity in the range of organizations to ensure equitable access.

    Borgert, Christopher J.; Mihaich, Ellen M.

    2012-01-01

    Background: There is an ongoing discussion on the provenance of toxicity testing data regarding how best to ensure its validity and credibility. A central argument is whether journal peer-review procedures are superior to Good Laboratory Practice (GLP) standards employed for compliance with regulatory mandates. Objective: We sought to evaluate the rationale for regulatory decision making based on peer-review procedures versus GLP standards. Method: We examined pertinent published literature regarding how scientific data quality and validity are evaluated for peer review, GLP compliance, and development of regulations. Discussion: Some contend that peer review is a coherent, consistent evaluative procedure providing quality control for experimental data generation, analysis, and reporting sufficient to reliably establish relative merit, whereas GLP is seen as merely a tracking process designed to thwart investigator corruption. This view is not supported by published analyses pointing to subjectivity and variability in peer-review processes. Although GLP is not designed to establish relative merit, it is an internationally accepted quality assurance, quality control method for documenting experimental conduct and data. Conclusions: Neither process is completely sufficient for establishing relative scientific soundness. However, changes occurring both in peer-review processes and in regulatory guidance resulting in clearer, more transparent communication of scientific information point to an emerging convergence in ensuring information quality. The solution to determining relative merit lies in developing a well-documented, generally accepted weight-of-evidence scheme to evaluate both peer-reviewed and GLP information used in regulatory decision making where both merit and specific relevance inform the process.

As previously reported, when rVSV(MΔ51)-M3 was used in an orthotopic model of hepatocellular carcinoma (HCC) in rats, it suppressed inflammatory cell migration to the virus-infected tumor site, which allowed for enhanced intratumoral virus replication leading to increased tumor necrosis and substantially prolonged survival. These encouraging results led to the development of this vector for clinical translation in patients with HCC. However, a scalable current Good Manufacturing Practice (cGMP)-compliant manufacturing process has not been described for this vector. To produce the quantities of high-titer virus required for clinical trials, a process that is amenable to GMP manufacturing and scale-up was developed. We describe here a large-scale (50-liter) vector production process capable of achieving crude titers on the order of 10(9) plaque-forming units (PFU)/ml under cGMP. This process was used to generate a master virus seed stock and a clinical lot of the clinical trial agent under cGMP with an infectious viral titer of approximately 2 × 10(10) PFU/ml (total yield, 1 × 10(13) PFU). The lot has passed all U.S. Food and Drug Administration-mandated release testing and will be used in a phase 1 clinical translational trial in patients with advanced HCC.

  1. The adoption of good laboratory practice principles by Italian test facilities.

    The principles of good laboratory practice (GLP) can be considered as a code of general behaviour potentially applicable to all experimental studies, although they were first conceived for harmonizing the conduct and assessment of toxicological tests designed to evaluate the impact of chemical substances on human health and the environment. From a general standpoint, therefore, GLP criteria aim at generating credible, comparable and cost-effective experimental information that can in turn make the decision-making process easier and sounder. On the other hand, of equal importance at the global level is the availability of and access to the wealth of critically assessed, self-consistent chemical data thus produced. Under both respects a key role is played by the activities undertaken under the aegis of international bodies such as the Organisation for Economic Cooperation and Development (OECD), the Commission of the European Union (CEU) and the International Register of Potentially Toxic Chemicals of the United Nations Environment Programme (IRPTC-UNEP). This cultural and scientific humus has been incorporated into legal provisions by most industrial countries to regulate production and commercialization of chemical substances. As regards Italy, the act DLvo no. 120 of 27 January 1992 focuses on the adoption of GLP principles by national test facilities and covers all possible categories of chemicals, namely industrial substances, pharmaceuticals, cosmetics, pesticides, food additives and still others. Accordingly, the compliance status with GLP principles of a test facility is ascertained by inspections carried out by public officers following a detailed procedure which will eventually result in the above acknowledgement provided that no major deviations in the laboratory performance are detected.(ABSTRACT TRUNCATED AT 250 WORDS)

    The multi-stage cascade impactor (CI) is widely used to determine aerodynamic particle size distributions (APSDs) of orally inhaled products. Its size-fractionating capability depends primarily on the size of nozzles of each stage. Good Cascade Impactor Practice (GCIP) requires that these critical dimensions are linked to the accuracy of the APSD measurement based on the aerodynamic diameter size scale. Effective diameter (Deff) is the critical dimension describing any nozzle array, as it is directly related to stage cut-point size (d50). d50 can in turn be determined by calibration using particles of known aerodynamic diameter, providing traceability to the international length standard. Movements in Deff within manufacturer tolerances for compendial CIs result in the worst case in shifts in d50 of <±10%. Stage mensuration therefore provides satisfactory control of measurement accuracy. The accurate relationship of Deff to d50 requires the CI system to be leak-free, which can be checked by sealing the apparatus at the entry to the induction port and isolating it from the vacuum source and measuring the rate of pressure rise before each use. Mensuration takes place on an infrequent basis compared with the typical interval between individual APSD determinations. Measurement of stage flow resistance (pressure drop; ΔPstage) could enable the user to know that the CI stages are fit for use before every APSD measurement, by yielding an accurate measure of Deff. However, more data are needed to assess the effects of wear and blockage before this approach can be advocated as part of GCIP.

    Agricultural land management has great influences on soil properties, in particular on microbial communities, due to their sensitivity to the perturbations of the soils. This is even more relevant in Mediterranean agricultural areas under semi-arid conditions. The Mediterranean belt is suffering from an intense degradation of its soils due to the millennia of intense land use and due to unsustainable management practices. As a consequence this area is suffering from a depletion of N content. In this work we investigated the effect of several traditional agricultural management practices on specific functional groups related to the nitrogen cycle in the soil. A field experiment was performed with orchard orange trees (citrus sinesis) in Eastern Spain to assess the long-term effects of ploughing with inorganic fertilization (PI) and ecological practices (EP) (chipped pruned branches and weeds as well as manure from sheep and goats) on microbes that can undertake nitrogen fixation and denitrification. Nine samples of soil were taken from every treatment, near the drip irrigation point and in a zone without the influence of drip irrigation (between trees row), and total DNA extracted. DNA samples were stored at minus-20°C to be analysed by qPCR. Microbial populations involved in the N biochemical cycle were analysed by targeted amplification of key functional biomarker genes: the abundance of nifH (nitrogen fixation), nirS, nirK and nosZ (denitrification) detected by quantitative PCR (qPCR) has shown significant differences between treatments with higher abundance of all four genes in soils from ecological agricultural treatments. This may indicate that the ecological treatment created conditions that are more suitable for N cyclers in the soil and a better fertility and quality status of these soils.

    Sustainable agricultural production relies on soil communities as the main actors in key soil processes necessary to maintain sustainable soil functioning. Soil biodiversity influences soil physical and chemical characteristics and thus the sustainability of crop and agro-ecosystems functioning. Agricultural practices (e.g.: soil tillage, pesticides and fertilizer applications, irrigation) may affects negatively or positively soil biodiversity and abundances by modifying the relationships between organisms in the soil ecosystem. The present study aimed to study the influence of agricultural practices of three crops (potato, onion and maize) under Mediterranean climate conditions on soil macro- and mesofauna during their entire crop cycles. Effects on soil communities were assessed at a higher tier of environmental risk assessment comprising field testing of indigenous edaphic communities in a selected study-site located in a major agriculture region of Central Portugal, Ribatejo e Oeste, neighbouring protected wetlands. A reference site near the agricultural field site was selected as a Control site to compare the terrestrial communities' composition and variation along the crop cycle. The field soil and Control site soil are sandy loam soils. Crops irrigation was performed by center-pivot (automated sprinkler that rotates in a half a circle area) and by sprinklers. Soil macro- and mesofauna were collected at both sites (field and Control) using two methodologies through pitfall trapping and soil sampling. The community of soil macro- and mesofauna of the three crops field varied versus control site along the crops cycles. Main differences were due to arachnids, coleopterans, ants and adult Diptera presence and abundance. The feeding activity of soil fauna between control site and crop areas varied only for potato and onion crops vs. control site but not among crops. Concentration of pesticides residues in soil did not cause apparent negative effects on the soil

    The agriculture industry, including farmers who rely on advanced technologies, increasingly use light detection and ranging (lidar) data for crop management to enhance agricultural productivity. Annually, the combination of greater yields and reduced crop losses is estimated to increase revenue by \\$2 billion for America's farmers when terrain data derived from lidar are available for croplands. Additionally, the Natural Resources Conservation Service (NRCS) estimates that the value of improved services for farmers, through its farm assistance program, would be \\$79 million annually if lidar-derived digital elevation models (DEMs) are made available to the public.The 3D Elevation Program (3DEP) of the U.S. Geological Survey provides the programmatic infrastructure to generate and supply superior, lidar-derived terrain data to the agriculture industry, which would allow farms to refine agricultural practices and produce crops more efficiently. By providing data to users, 3DEP reduces users’ costs and risks, allowing them to concentrate on mission objectives. 3DEP includes (1) data acquisition partnerships that leverage funding, (2) contracts with experienced private mapping firms, (3) technical expertise, lidar data standards and specifications, and (4) most importantly, public access to high-quality 3D elevation data.

    Watershed-scale management efforts to reduce nutrient loads and improve the conservation of lakes in agricultural watersheds require effective integration of a variety of agricultural conservation best management practices (BMPs). This paper documents watershed-scale assessments of the influence of multiple integrated BMPs on oxbow lake nutrient concentrations in a 625-ha watershed of intensive row-crop agricultural activity during a 14-yr monitoring period (1996-2009). A suite of BMPs within fields and at field edges throughout the watershed and enrollment of 87 ha into the Conservation Reserve Program (CRP) were implemented from 1995 to 2006. Total phosphorus (TP), soluble reactive phosphorus (SRP), ammonium, and nitrate were measured approximately biweekly from 1996 to 2009, and total nitrogen (TN) was measured from 2001 to 2009. Decreases in several lake nutrient concentrations occurred after BMP implementation. Reductions in TP lake concentrations were associated with vegetative buffers and rainfall. No consistent patterns of changes in TN or SRP lake concentrations were observed. Reductions in ammonium lake concentrations were associated with conservation tillage and CRP. Reductions in nitrate lake concentrations were associated with vegetative buffers. Watershed simulations conducted with the AnnAGNPS (Annualized Agricultural Non-Point Source) model with and without BMPs also show a clear reduction in TN and TP loads to the lake after the implementation of BMPs. These results provide direct evidence of how watershed-wide BMPs assist in reducing nutrient loading in aquatic ecosystems and promote a more viable and sustainable lake ecosystem.

    Rice agricultural practices and hydroperiod dates must be determined to obtain information on water management practices and their environmental effects. Spectral indices derived from an 8-day MODIS composite allows to identify rice phenometrics at varying degrees of success. The aims of this study were (1) to assess the dynamics of the Normalized Difference Vegetation Index (NDVI), Normalized Difference Water Index (NDWI(1) and NDWI(2)) and Shortwave Angle Slope Index (SASI) in relation to rice agricultural practices and hydroperiod, and (2) to assess the capability for these indices to detect phenometrics in rice under different flooding regimes. Two rice farming areas in Spain that are governed under different water management practices, the Ebro Delta and Orellana, were studied over a 12-year period (2001-2012). The index time series autocorrelation function was calculated to determine index dynamics in both areas. Secondly, average indices were calculated to identify significant points close to key agricultural and flooding dates, and index behaviors and capacities to identify phenometrics were assessed on a pixel level. The index autocorrelation function produced a regular pattern in both zones, being remarkably homogeneous in the Ebro Delta. It was concluded that a combination of NDVI, NDWI(1), NDWI(2) and SASI may improve the results obtained through each index. NDVI was more effective at detecting the heading date and flooding trends in the Ebro Delta. NDWI(1), NDWI(2) and SASI identified the harvest and the end of environmental flooding in the Delta, and the flooding in Orellana, more effectively. These results may set strong foundations for the development of new strategies in rice monitoring systems, providing useful information to policy makers and environmental studies.

    Proper use of drugs can be defined as the use of the right product, in a correct dosage, during an adequate length of time, for a given patient and provided he has no serious side effects.It is virtually impossible, with such a number of drugs, such a number of clinical situations to prescribe adequately without using references or guidelines. References may lead to a unique choice, when the diagnosis is certain and the drug to be given is unique. With a good initial and continuous medical education, doctors can take easily this type of decision. The Summary of Products Characteristics (SPC) helps them; by sticking to this fundamental reference, prescription might be more precise and safe. In a lot of clinical situations the choice between a large numbers of therapeutic strategies necessitates use of a guideline based on scientific knowledge. Finally, a given therapeutic strategy can be as effective as and considerably less expensive than another. In such cases, payers can drive doctors to the prescription of the less expensive strategy.Some difficulties are common to all references and guidelines: 1. A lot of clinical situations are not covered by guidelines. 2. Guidelines should be updated each time there is a modification of knowledge: it is extremely difficult to do. 3. A great number of guidelines exist, issued by scientific community, health authorities or the payers. Sometime you can find a proposition in a guideline and the reverse in another guideline. It could be confusing. 4. Guidelines should be evaluated rigorously to know if they fulfil their goals. 5. Some of those guidelines simply cannot help doctors. They are too complex or do not take into account practical situations.We have made an inventory of those various guidelines and their weaknesses and we propose some solutions to increase their utility. We propose an analysis of the situation and some solutions to improve the quality and the relevance of the guidelines: to create groups of coordination

    Work practices can influence exposure, especially in small-scale operations conducted by mobile work crews. This study evaluated the use of information on good work practice in control guidance sheets adapted from UK Silica Essentials guidance sheets by trained workers and supervisors employed in small-scale concrete and masonry demolition operations. A one-page employee silica task-based control guidance sheet for each of four demolition tasks and multiple-page silica control guidance for supervisors were developed. Interactive, hands-on worker training on these task-based good work practice controls was developed. Training was presented to 26 participants from two demolition crews. Feedback on the training and task-based good work practice control guidance sheets was elicited. Observations of work practices were made before and after training. Participants indicated gains in knowledge and checklists were used to document skill attainment. The quality of the training and usefulness of the material/skills was rated high by trainees. Increased use of water to suppress dust and wet cleaning methods on the job were documented following the training. Additional follow-up after training is required to determine long-term impact on sustained changes in work practices, and to evaluate the need for refresher training.

    Soil erosion can lead to severe destruction of agricultural sustainability that affects not only productivity, but the entire ecosystem in the neighboring areas. Sediments transported together with the associated nutrients and chemicals can significantly impact downstream water bodies. Various conservation and management practices implemented individually or integrated together as a system can be used to reduce the negative impacts on agricultural watersheds from soil erosion. Hydrological models are useful tools for decision makers when selecting the most effective combination of management practices to reduce pollutant loads within a watershed system. The Annualized Agricultural Non-point Source (AnnAGNPS) pollutant loading management model can be used to analyze the effectiveness of diverse management and conservation practices that can control or reduce the impact of soil erosion processes and subsequent sediment loads in agricultural watersheds. A 506 km2 Mediterranean medium-size watershed (Carapelle) located in Apulia, Southern Italy was used as a case study to evaluate the model and best management practices (BMPs) for sediment load control. A monitoring station located at the Ordona bridge has been instrumented to continuously monitor stream flow and suspended sediment loads. The station has been equipped with an ultrasound stage meter and a stage recorder to monitor stream flow. An infrared optic probe was used to measure suspended sediment concentrations (Gentile et al., 2010 ). The model was calibrated and validated in the Carapelle watershed on an event basis (Bisantino et al., 2013), and the validated model was used to evaluate the effectiveness of BMPs on sediment reduction. Various management practices were investigated including evaluating the impact on sediment load of: (1) converting all cropland areas into forest and grass covered conditions; (2) converting the highest eroding cropland areas to forest or grass covered conditions; and (3

    The profile of glucosinolates in relation to the antioxidant capacity of five Brassica vegetables (Broccoli, Cauliflower, Kohlrabi, White and Red Cabbage) grown by organic and conventional agricultural practices in Transylvania region-Romania, were determined and compared. The qualitative and quantitative compositions of glucosinolates were determined by HPLC-PDA technique. The antioxidant capacity was comparatively determined by ABTS, DPPH, FRAP and Folin-Ciocalteu assays. The highest glucosinolates levels were found in the Broccoli samples grown under conventional practices (14.24 μmol/g dry weight), glucoraphanin, glucobrassicin and neo-glucobrassicin being the major components. The total glucosinolates content was similar in Kohlrabi and Cauliflower (4.89 and 4.84 μmol/g dry weight, respectively), the indolyl glucosinolates were predominant in Kohlrabi, while the aliphatic derivatives (sinigrin and glucoiberin) were major in Cauliflower. In Cabbage samples, the aliphatic glucosinolates were predominat against indolyl derivatives, glucoraphanin and glucoiberin being the main ones in Red Cabbage. The principal component analysis was applied to discriminate among conventional and organic samples and demonstrated non-overlaps between these two agricultural practices. Meanwhile it was shown that glucosinolates may represent appropriate molecular markers of Brassica vegetables, their antioxidant capacity being higher in organic crops, without significant differences among different Brassica varieties.

    This article presents the findings of an audit on venous leg ulceration prevalence in a community area as a framework for discussing the concept and importance of audit as a tool to inform practice and as a means to benchmark care against national or international standards. It is hoped that the discussed audit will practically demonstrate how such procedures can be implemented in practice for those who have not yet undertaken it, as well as highlighting the unexpected extra benefits of this type of qualitative data collection that can often unexpectedly inform practice and influence change. Audit can be used to measure, monitor and disseminate evidence-based practice across community localities, facilitating the identification of learning needs and the instigation of clinical change, thereby prioritising patient needs by ensuring safety through the benchmarking of clinical practice.

    Bioenergy is generating tremendous interest as an alternative energy source that is both environmentally friendly and economically competitive. The amount of land designated for agriculture is expected to expand, including changes in the current distribution of crops, as demand for biofuels increases as a carbon neutral alternative fuel source. However, the influence of agriculture on the carbon cycle is complex, and varies depending on land use change and management practices. The purpose of this research is to integrate agriculture in the carbon-nitrogen based Community Land Model (CLM) to evaluate the above and below ground carbon storage for corn, soybean, and wheat crop lands. The new model, CLM-Crop simulates carbon allocation during four growth stages, a soybean nitrogen fixation scheme, fertilizer, and harvest practices. We present results from this model simulation, which includes the impact of a new dynamic roots module to simulate the changing root structure and depth with growing season based on the availability of water and nitrogen in the root zone and a retranslocation scheme to simulate redistribution of nitrogen from leaves, roots, and stems to grain during organ development for crop yields, leaf area index (LAI), carbon allocation, and changes in soil carbon budgets under various practices such as fertilizer and residue management. Simulated crop yields for corn, soybean and wheat are in general agreement with measurements. Initial model results indicate a loss of soil organic carbon over cultivated lands after removal of natural vegetation which continues in the following years. Soil carbon in crop lands is a strong function of the residue management and has the potential to impact crop yields significantly.

    Traditional agriculture in rainfed uplands of India has been experiencing low agricultural productivity as the lands suffer from poor soil fertility, susceptibility to water erosion and other external pressures of development and climate change. A shift toward more sustainable cropping systems such as conservation agriculture production systems (CAPSs) may help in maintaining soil quality as well as improving crop production and farmer’s net economic benefit. This research assessed the effects over 3 years (2011–2014) of reduced tillage, intercropping, and cover cropping practices customized for maize-based production systems in upland areas of Odisha, India. The study focused on crop yield, system productivity and profitability through maize equivalent yield and dominance analysis. Results showed that maize grain yield did not differ significantly over time or among CAPS treatments while cowpea yield was considered as an additional yield in intercropping systems. Mustard and horsegram grown in plots after maize cowpea intercropping recorded higher grain yields of 25 and 37%, respectively, as compared to those without intercropping. Overall, the full CAPS implementation, i.e., minimum tillage, maize–cowpea intercropping and mustard residue retention had significantly higher system productivity and net benefits than traditional farmer practices, i.e., conventional tillage, sole maize cropping, and no mustard residue retention. The dominance analysis demonstrated increasing benefits of combining conservation practices that exceeded thresholds for farmer adoption. Given the use of familiar crops and technologies and the magnitude of yield and income improvements, these types of CAPS should be acceptable and attractive for smallholder farmers in the area. This in turn should support a move toward sustainable intensification of crop production to meet future household income and nutritional needs. PMID:27471508

    Increasing the world soils carbon stocks by a factor of 4 per mil annually would compensate the annual net increase of CO2 concentration in the atmosphere. This statement is the core of an initiative launched by the French government at the recent COP21, followed by many countries and international bodies, which attracts political attention to the storage potential of C in soils. Compared to forest and pasture soils, agricultural soils have a higher C storage potential, because they are often characterized by low C contents, and increasing their C content is associated with benefits in terms of soil properties and ecosystem services. Here we quantified, under temperate conditions, the additional C storage related to the implementation of two set of practices that are recognized to be in the framework of agroecology: conservation tillage on the one hand and agroforestry on the other hand. These studies were based on long-term experiments, a 16-years comparison on cropping systems on luvisols in the Paris area and a 18-year-old silvoarable agroforestry trial, on fluvisols in southern France, the main crops being cereals in both cases. C stocks were measured on an equivalent soil mass basis. Both systems allowed for a net storage of C in soils, which are, for the equivalent of the 0-30 cm tilled layer, of 0.55 ± 0.16 t ha- 1 yr- 1 for conservation agriculture (i.e. no tillage with permanent soil coverage with an associated plant, fescue or alfalfa) and of 0.25 ± 0.03 t ha-1 yr-1 for the agroforestry system. These results are in line with estimates proposed in a recent French national assessment concerning the potential of agricultural practices to reduce greenhouse gas emissions. Compared to recent literature, they further show that practices that increase C inputs to soil through additional biomass production would be more effective to store C in soil (tree rows, cover crops in conservation agriculture) than practices, such as no-tillage, that are assumed to reduce

    The disposal of municipal sewage sludge is an important environmental problem presently facing society. Because sludge is rich in plant nutrients such as nitrogen and phosphorous, land application as a fertilizer has been proposed as a cost-effective means of disposal. This method of disposal, however, is frequently the subject of public health concern since municipal sludge may contain heavy metals that potentially could be introduced into the human food chain. This study examined metal concentrations in two agricultural species at a study site where ecosystem restoration practices (liming and tilling) had been conducted for 5 years following 11 years of sludge enrichment. 11 refs., 2 tabs.

    Phosphorus (P) is an essential nutrient for plant growth. In intensively farmed areas, excessive applications of animal manure and mineral P fertilizers to soils have raised both economic and ecological concerns. P accumulation in agricultural soils leads to increased P losses to surface waterbodies contributing to eutrophication. Increasing soil P content over time in agricultural soils is often correlated with agricultural practices; in Brittany (NW France), an intensive livestock farming region, soil P content is well correlated with animal density (Lemercier et al.,2008). Thus, a better understanding of the factors controlling P distribution is required to enable environmental assessment of P risk. The aim of this study was to understand spatial distribution of extractable (Olsen method) and total P contents and its controlling factors at the catchment scale in order to predict P contents at regional scale (Brittany). Data on soil morphology, soil tests (including P status, particles size, organic carbon…) for 198 punctual positions, crops succession since 20 years, agricultural systems, field and animal manure management were obtained on a well-characterized catchment (ORE Agrhys, 10 km²). A multivariate analysis with mixed quantitative variables and factors and a digital soil mapping approach were performed to identify variables playing a significant role in soil total and extractable P contents and distribution. Spatial analysis was performed by means of the Cubist model, a decision tree-based algorithm. Different scenarios were assessed, considering various panels of predictive variables: soil data, terrain attributes derived from digital elevation model, gamma-ray spectrometry (from airborne geophysical survey) and agricultural practices information. In the research catchment, mean extractable and total P content were 140.0 ± 63.4 mg/kg and 2862.7 ± 773.0 mg/kg, respectively. Organic and mineral P inputs, P balance, soil pH, and Al contents were

    2011-01-01

    Background Health services across Europe provide health care for migrant patients every day. However, little systematic research has explored the views and experiences of health care professionals in different European countries. The aim of this study was to assess the difficulties professionals experience in their service when providing such care and what they consider constitutes good practice to overcome these problems or limit their negative impact on the quality of care. Methods Structured interviews with open questions and case vignettes were conducted with health care professionals working in areas with high proportion of migrant populations in 16 countries. In each country, professionals in nine primary care practices, three accident and emergency hospital departments, and three community mental health services (total sample = 240) were interviewed about their views and experiences in providing care for migrant patients, i.e. from first generation immigrant populations. Answers were analysed using thematic content analysis. Results Eight types of problems and seven components of good practice were identified representing all statements in the interviews. The eight problems were: language barriers, difficulties in arranging care for migrants without health care coverage, social deprivation and traumatic experiences, lack of familiarity with the health care system, cultural differences, different understandings of illness and treatment, negative attitudes among staff and patients, and lack of access to medical history. The components of good practice to overcome these problems or limit their impact were: organisational flexibility with sufficient time and resources, good interpreting services, working with families and social services, cultural awareness of staff, educational programmes and information material for migrants, positive and stable relationships with staff, and clear guidelines on the care entitlements of different migrant groups.

    About half of the terrestrial biosphere is under direct human influence through land management (i.e., agricultural areas and managed forests). Changing management practices is therefore a promising avenue for climate change mitigation. The mitigation potential arising from changes in land management practices has been mainly evaluated in terms of carbon storage and GHG emissions [2]. On the other hand, these practices can also influence climate by altering the physical properties of the land surface, but these effects have received less attention so far. Here we show that peak temperatures during heat heaves can be attenuated through cropland albedo management [2]. We first present observational evidence that a substantial summer albedo increase can be obtained by switching from conventional to no-till agriculture. Then, using a regional climate model, we investigate the biogeophysical effect of a full conversion to no-till management over Europe. The cooling effect owing to albedo increase under no-till farming appears to be strongly amplified during warm events. This is due to the low cloud cover during these events, thus leading to a more efficient radiative cooling from albedo change. This implies a strong potential of no-till farming to mitigate heat wave impacts. The reduced evaporation associated with the crop residue cover tends to counteract the albedo-induced cooling, but during hot days the albedo effect remains the dominating factor. For heatwave summer days the local cooling effect gained from no-till practice is of the order of 2 degrees. These findings strongly suggest that the biogeophysical effect of management practices should be considered in the design of climate mitigation policies involving land management.

    This guide is intended to assist facility maintenance organizations in the review of existing methods and in the development of new methods for establishing a maintenance Seasonal Facility Preservation program. It is expected that each DOE facility may use approaches or methods different from those defined in this guide. The specific guidelines that follow reflect generally accepted industry practices. Therefore, deviation from any particular guideline would not, in itself, indicate a problem. If substantive differences exist between the intent of this guideline and actual practice, management should evaluate current practice to determine the need to include/exclude proposed features. A change in maintenance practice would be appropriate if a performance weakness were determined to exist. The development, documentation, and implementation of other features that further enhance these guidelines for specific applications are encouraged.

  14. An investigation of the practice of scientific inquiry in secondary science and agriculture courses

    Grady, Julie R.

    The purpose of this exploratory qualitative study was to investigate the practice of scientific inquiry in two secondary biology classes and one agriculture class from different schools in different communities. The focus was on teachers' interests and intentions for the students' participation in inquiry, the voices contributing to the inquiry, and students' opportunities to confront their conceptions of the nature of science (NOS). The Partnership for Research and Education in Plants (PREP) served as the context by providing students with opportunities to design and conduct original experiments to help elucidate the function(s) of a disabled gene in Arabidopsis thaliana . Transcripts of teacher and student semi-structured interviews, field notes of classroom observations and classroom conversations, and documents (e.g., student work, teacher handouts, school websites, PREP materials) were analyzed for evidence of the practice of scientific inquiry. Teachers were interested in implementing inquiry because of potential student learning about scientific research and because PREP supports course content and is connected to a larger scientific project outside of the school. Teachers' intentions regarding the implementation of inquiry reflected the complexity of their courses and the students' previous experiences. All inquiries were student-directed. The biology students' participation more closely mirrored the practice of scientists, while the agriculture students were more involved with the procedural display of scientific inquiry. All experiences could have been enhanced from additional knowledge-centered activities regarding scientific reasoning. No activities brought explicit attention to NOS. Biology activities tended to implicitly support NOS while the agriculture class activities tended to implicitly contradict NOS. Scientists' interactions contributed to implied support of the NOS. There were missed opportunities for explicit attention to NOS in all classes

    Dissolved organic carbon (DOC) fluxes are recently increasing in surface waters of humid climate regions. Due to its substantial importance for leaching processes, aquatic foodwebs, and drinking water purification a better understanding of sources and pathways of DOC is needed. Therefore this study aims to analyse and simulate DOC fluxes in agricultural ecosystems with selected crop rotations. A data set of 24 lysimeters of the UFZ Lysimeter station at Falkenberg (Saxony-Anhalt) covering nine years of DOC investigation has been selected and examined. The data set covers a wide range of climatic conditions with deviating management practices for grasslands and agricultural crop rotations. The monthly DOC concentrations assessed in the leached water range from 2.4 to 34.1 mg /l. DOC concentrations depend on temperature, precipitation and discharge. The type of crop grown on the lysimeter is an important trigger for DOC leaching - especially lysimeters used as pasture, or planted with rape and carrots exhibit high DOC concentrations. Management practices and fertilizer application modify the leaching of DOC and offer potentials to reduce DOC losses. The results form the basis of further process simulation studies and upscaling of the results to the small catchment scale.

    The impact of agricultural practices/ activities on the environment has been falling in many areas of Europe due to the widespread exodus of inhabitants from rural areas. The associated abandonment of agricultural lands has enabled a wide range of wild animals to prosper in the countryside, including birds, ungulates and large carnivores. One consequence has been the increase in ticks and associated tick-borne diseases which now constitute a greater threat for public health than earlier. The aim of the present study was to compare tick densities in different habitats (pasture, meadow, fallow land, post-fire areas) to assess the impact of different agricultural practices on tick densities in vicinities close to human habitation. Between September 2011 and June 2014, 2985 Dermacentor reticulatus ticks were collected by conventional dragging, in the Mazowieckie (Mazovia) and Warmińsko-Mazurskie (Masuria) regions of Poland. In each region, 3 study sites were selected, each situated near surface water sources (i.e., ponds or canals). At each site, three neighboring habitats of surface area 150-600 m(2) were dragged: one on a cattle/horse pasture; the second on meadow; the third on fallow land (abandoned field or meadow), at least twice during each spring and autumn. Additionally, four post-fire areas (one in 2013 and three in 2014) were identified in the Mazowieckie region, and dragging was conducted there in spring and autumn, including in each case a 'control area' comprising intact unburned fallow land situated in close vicinity to the burned areas. Eight hundred D. reticulatus ticks were collected and the densities were compared by multifactorial ANOVA. The highest tick densities were recorded on the fallow lands, and the lowest - on the grazed pastures. Tick densities were up to 10 × times higher on the control sites compared to neighboring post-fire sites.

    2015-03-01

    The Sacramento-San Joaquin Delta's (Delta) beneficial uses for humans and wildlife are impaired by elevated methylmercury (MeHg) concentrations in fish. MeHg is a neurotoxin that bioaccumulates in aquatic food webs. The total maximum daily load (TMDL) implementation plan aimed at reducing MeHg in Delta fish obligates dischargers to conduct MeHg control studies. Over 150 stakeholders collaborated to identify 24 management practices (MPs) addressing MeHg nonpoint sources (NPS) in three categories: biogeochemistry (6), hydrology (14), and soil/vegetation (4). Land uses were divided into six categories: permanently and seasonally flooded wetlands, flooded and irrigated agricultural lands, floodplains, and brackish-fresh tidal marshes. Stakeholders scored MPs based on seven criteria: scientific certainty, costs, MeHg reduction potential, spatial applicability, technical capacity to implement, negative impacts to beneficial uses, and conflicting requirements. Semi-quantitative scoring for MPs applicable to each land use (totaling >400 individual scores) led to consensus-based prioritization. This process relied on practical experience from diverse and accomplished NPS stakeholders and synthesis of 17 previous studies. Results provide a comprehensive, stakeholder-driven prioritization of MPs for wetland and irrigated agricultural land managers. Final prioritization highlights the most promising MPs for practical application and control study, and a secondary set of MPs warranting further evaluation. MPs that address hydrology and soil/vegetation were prioritized because experiences were positive and implementation appeared more feasible. MeHg control studies will need to address the TMDL conundrum that MPs effective at reducing MeHg exports could both exacerbate MeHg exposure and contend with other management objectives on site.

    Sustainable water management typically emphasizes water resource quantity, with focus directed at availability and use practices. When attention is placed on sustainable water quality management, the holistic, cross-sector perspective inherent to sustainability is often lost. Proper water quality management is a critical component of sustainable development practices. However, sustainable development definitions and metrics related to water quality resilience and management are often not well defined; water quality is often buried in large indicator sets used for analysis, and the policy regulating management practices create sector specific burdens for ensuring adequate water quality. In this research, we investigated the methods by which water quality is evaluated through internationally applied indicators and incorporated into the larger idea of "sustainability." We also dissect policy's role in the distribution of responsibility with regard to water quality management in the United States through evaluation of three broad sectors: urban, agriculture, and environmental water quality. Our research concludes that despite a growing intention to use a single system approach for urban, agricultural, and environmental water quality management, one does not yet exist and is even hindered by our current policies and regulations. As policy continues to lead in determining water quality and defining contamination limits, new regulation must reconcile the disparity in requirements for the contaminators and those performing end-of-pipe treatment. Just as the sustainable development indicators we researched tried to integrate environmental, economic, and social aspects without skewing focus to one of these three categories, policy cannot continue to regulate a single sector of society without considering impacts to the entire watershed and/or region. Unequal distribution of the water pollution burden creates disjointed economic growth, infrastructure development, and policy

    Evaluating the effectiveness of agricultural land management practices in minimizing environmental impacts using models is challenged by the presence of inherent uncertainties during the model development stage. One issue faced during the model development stage is the uncertainty involved in model parameterization. Using a single optimized set of parameters (one snapshot) to represent baseline conditions of the system limits the applicability and robustness of the model to properly represent future or alternative scenarios. The objective of this study was to develop a framework that facilitates model parameter selection while evaluating uncertainty to assess the impacts of land management practices at the watershed scale. The model framework was applied to the Lake Creek watershed located in southwestern Oklahoma, USA. A two-step probabilistic approach was implemented to parameterize the Agricultural Policy/Environmental eXtender (APEX) model using global uncertainty and sensitivity analysis to estimate the full spectrum of total monthly water yield (WYLD) and total monthly Nitrogen loads (N) in the watershed under different land management practices. Twenty-seven models were found to represent the baseline scenario in which uncertainty of up to 29% and 400% in WYLD and N, respectively, is plausible. Changing the land cover to pasture manifested the highest decrease in N to up to 30% for a full pasture coverage while changing to full winter wheat cover can increase the N up to 11%. The methodology developed in this study was able to quantify the full spectrum of system responses, the uncertainty associated with them, and the most important parameters that drive their variability. Results from this study can be used to develop strategic decisions on the risks and tradeoffs associated with different management alternatives that aim to increase productivity while also minimizing their environmental impacts.

    Though large progress has been achieved in the last decades, net GHG emissions from the agricultural sector are still more poorly quantified than in other sectors. In this study, we examined i) technical mitigation options likely to store carbon in agricultural soils, ii) their potential of additional C storage per unit surface area and iii) applicable areas in mainland France. We considered only agricultural practices being technically feasible by farmers and involving no major change in either production systems or production levels. Moreover, only currently available techniques with validated efficiencies and presenting no major negative environmental impacts were taken into account. Four measures were expected to store additional C in agricultural soils: - Reducing tillage: either a switch to continuous direct seeding, direct seeding with occasional tillage once every five years, or continuous superficial (<15 cm) tillage. - Introducing cover crops in cropping systems: sown between two cash crops on arable farms, in orchards and vineyards (permanent or temporary cover cropping) . - Expanding agroforestry systems; planting of tree lines in cultivated fields and grasslands, and hedges around the field edges. - Increasing the life time of temporary sown grasslands: increase of life time to 5 years. The recent literature was reviewed in order to determine long term (>20yrs) C storage rates (MgC ha-1 y-1,) of cropping systems with and without the proposed practice. Then we analysed the conditions for potential application, in terms of feasibility, acceptance, limitation of yield losses and of other GHG emissions. According to the literature, additional C storage rates were 0.15 (0-0.3) MgC ha-1 y-1 for continuous direct seeding, 0.10 (0-0.2) MgC ha-1 y-1for occasional tillage one year in five, and 0.0 MgC ha-1 y-1 for superficial tillage. Cover crops were estimated to store 0.24 (0.13-0.37) MgC ha-1 y-1 between cash crops and 0.49 (0.23-0.72) MgC ha-1 y-1 when

    The extensive use of fertilizers has become one of the most challenging environmental issues in agricultural catchment areas. In order to reduce the negative impacts from agricultural activities and to accomplish the objectives of the European Water Framework Directive we must consider the implementation of sustainable agricultural practices. In this study, we assess sustainable agricultural practices based on reductions in N-fertilizer application rates (from 100% to 0%) and N-application methods (single, split and slow-release) across key agricultural land use classes in the Vouga catchment, Portugal. The SWAT model was used to relate sustainable agricultural practices, agricultural yields and N-NO3 water pollution deliveries. Results show that crop yields as well as N-NO3 exportation rates decrease with reductions in N-application rates and single N-application methods lead to lower crop yields and higher N-NO3 exportation rates as compared to split and slow-release N-application methods.

    Naturalistic methods of inquiry were used to investigate learning processes of above-average second, third, and fourth graders while practicing arithmetic with a computer. Because the software enabled the better students to accelerate through the practice material, they received practice in topics that had not yet been covered in class, and thus were attempting material which was new to them. It also happened that they encountered exercises that they had learned in class but had forgotten how to solve. This study reveals that when confronted by exercises they do not know how to solve, above average students use a variety of strategies that lead to their identification of solution algorithms, while not always understanding the underlying concepts. The article identifies the different problem solving strategies that students used, sorts them into categories, and illustrates them with examples from students' protocols. On the basis of the findings, suggestions are made for designing computer software for arithmetic practice that promotes student problem solving strategies along with mathematical understanding.

    We elaborated basic guiding principles that will be used to improve the content of the ENVRIPLUS e-Training Platform for multimedia education of Secondary School level teachers and students. The purpose is to favour teacher training and consequently students training on selected scientific themes faced within the ENVRIPLUS Research Infrastructures. "Best practices" could positively impacts on students by providing motivation on promoting scientific research and to increase the awareness of the Earth System complexity and Environmental challenges for its preservation and sustainability. Best practice teaching strategies represent an inherent part of a curriculum that exemplifies the connection and relevance identified in education research. The actions are designed to develop thinking and problem-solving skill through integration and active learning. Relationships are built though opportunities for communication and teamwork. Best practices motivate, engage and prompt student to learn and achieve. A starting list of principles is discussed in respect of the following main Best Practices pillars: • Identify the conceptual framework of the subject of the dissemination • Increase personal awareness of the individual potential • Easy personal elaboration and the connection of the subject with the school curriculum.

    Agricultural systems differ significantly throughout the world, making a 'one size fits all' approach to remote sensing and monitoring of agricultural landscapes problematic. The Joint Experiment for Crop Assessment and Monitoring (JECAM) was established in 2009 to bring together the global scientific community to work towards a set of best practices and recommendations for using earth observation data to map, monitor and report on agricultural productivity globally across an array of diverse agricultural systems. These methods form the research and development component of the Group on Earth Observation Global Agricultural Monitoring (GEOGLAM) initiative to harmonize global monitoring efforts and increase market transparency. The JECAM initiative brings together researchers from a large number of globally distributed, well monitored agricultural test sites that cover a range of crop types, cropping systems and climate regimes. Each test site works independently as well as together across multiple sites to test methods, sensors and field data collection techniques to derive key agricultural parameters, including crop type, crop condition, crop yield and soil moisture. The outcome of this project will be a set of best practices that cover the range of remote sensing monitoring and reporting needs, including satellite data acquisition, pre-processing techniques, information retrieval and ground data validation. These outcomes provide the research and development foundation for GEOGLAM and will help to inform the development of the GEOGLAM "system of systems" for global agricultural monitoring. The outcomes of the 2014 JECAM science meeting will be discussed as well as examples of methods being developed by JECAM scientists.

    In the past decade, stem cell therapy has been increasingly employed for the treatment of various diseases. Subsequently, there has been a great interest in the manufacture of stem cells under good manufacturing practice, which is required by law for their use in humans. The cells for sight Stem Cell Therapy Research Unit, based at UCL Institute of Ophthalmology, delivers somatic cell-based and tissue-engineered therapies to patients suffering from blinding eye diseases at Moorfields Eye Hospital (London, UK). The following article is based on our experience in the conception, design, construction, validation and manufacturing within a good manufacturing practice manufacturing facility based in the UK. As such the regulations can be extrapolated to the 28 members stated within the EU. However, the principles may have a broad relevance outside the EU.

    The U.S. Geological Survey (USGS) enhances and protects the quality of life in the United States by advancing scientific knowledge to facilitate effective management of hydrologic, biologic, and geologic resources. Results of selected USGS research and monitoring projects in agricultural landscapes are presented in this Fact Sheet. Significant environmental and social issues associated with agricultural production include changes in the hydrologic cycle; introduction of toxic chemicals, nutrients, and pathogens; reduction and alteration of wildlife habitats; and invasive species. Understanding environmental consequences of agricultural production is critical to minimize unintended environmental consequences. The preservation and enhancement of our natural resources can be achieved by measuring the success of improved management practices and by adjusting conservation policies as needed to ensure long-term protection.

    The aim of this study was to determine whether applying good practices of handling during the pre-weaning period have long-term effects on behavioral and physiological indicators, health status, and average daily gain (ADG) of crossbred Bos taurus × Bos indicus heifer calves. During the pre-weaning period, 98 crossbred of Holstein × Gir heifer calves were allotted into three treatments: (1) good practices of handling + brushing (GPB; n = 25), (2) good practices of handling (GP; n = 25), and (3) control (n = 48). Every 2 months, four evaluation periods (EV1 to EV4) were conducted to record data. Behavioral indicators comprised time to drive (TD), flight speed (FS), flight distance (FD), and composite reactivity score (CRS). Physiological indicators of acute stress during handling comprised respiratory and heart rates. Health status comprised data regarding occurrence of most common diseases (i.e., pneumonia and anaplasmosis). Collected data were analyzed by using a linear mixed model for repeated measures, Tukey's test, and chi-squared procedures. Treatment influenced (P < 0.05) TD, FS, and FD but not CRS (P = 0.78). From EV1 to EV3, the control calves had the lowest TD. The GPB group had lower FS than the control but did not differ from GP. The GPB group had lower FD means than the other two groups in EV2, EV3, and EV4. No differences (P > 0.05) due to treatment were observed on heart and respiratory rates, ADG, or occurrence of pneumonia and anaplasmosis. It was concluded that adoption of good practices of handling during pre-weaning period may lead to long-term positive effects.

  8. Agricultural management practices to sustain crop yields and improve soil and environmental qualities.

    PubMed

    Sainju, Upendra M; Whitehead, Wayne F; Singh, Bharat P

    2003-08-20

    In the past several decades, agricultural management practices consisting of intensive tillage and high rate of fertilization to improve crop yields have resulted in the degradation of soil and environmental qualities by increasing erosion and nutrient leaching in the groundwater and releasing greenhouses gases, such as carbon dioxide (CO2) and nitrous oxide (N2O), that cause global warming in the atmosphere by oxidation of soil organic matter. Consequently, management practices that sustain crop yields and improve soil and environmental qualities are needed. This paper reviews the findings of the effects of tillage practices, cover crops, and nitrogen (N) fertilization rates on crop yields, soil organic carbon (C) and N concentrations, and nitrate (NO3)-N leaching from the soil. Studies indicate that conservation tillage, such as no-till or reduced till, can increase soil organic C and N concentrations at 0- to 20-cm depth by as much as 7-17% in 8 years compared with conventional tillage without significantly altering crop yields. Similarly, cover cropping and 80-180 kg N ha(-1) year(-1) fertilization can increase soil organic C and N concentrations by as much as 4-12% compared with no cover cropping or N fertilization by increasing plant biomass and amount of C and N inputs to the soil. Reduced till, cover cropping, and decreased rate of N fertilization can reduce soil N leaching compared with conventional till, no cover cropping, and full rate of N fertilization. Management practices consisting of combinations of conservation tillage, mixture of legume and nonlegume cover crops, and reduced rate of N fertilization have the potentials for sustaining crop yields, increasing soil C and N storage, and reducing soil N leaching, thereby helping to improve soil and water qualities. Economical and social analyses of such practices are needed to find whether they are cost effective and acceptable to the farmers.

    This article presents a framework for the practical implementation of a 24-hour specialist palliative care advice line, illustrated by two case examples from the authors' experience. In the UK, National Institute for Health and Clinical Excellence guidance requires provision of 24-hour access to specialist palliative care advice for healthcare professionals and carers regardless of a patient's location. Effective implementation of a telephone advice line for specialist advice is one approach to addressing the current variability in palliative care service provision, both in the UK and elsewhere. The authors were unable to identify a model with documentation for ensuring adequate clinical governance of an advice line in the literature and so present their own. The accompanying case examples demonstrate the difference between 'evolution of services by demand' and taking a systemic approach to service design. Key recommendations for practice are outlined for an effective advice line service which incorporates training and education into the clinical governance structures of the host organization.

  10. A framework for good practice in interagency interventions with cases of self-neglect.

    2005-04-01

    Self-neglect is probably more common than has generally been thought and gives rise to a number of difficult conceptual, identification and intervention problems for health and social care workers. These patient management issues are compounded by the lack of any evidence-base for practice which nurses can draw on when faced with managing people who self-neglect. Nurses working with self-neglecters operate in an interdisciplinary context which includes professional groups, such as environmental health officers, who do not normally figure within health and social care teams. In the absence of such an evidence-base, a pragmatic solution in the form of a framework for interagency practice has been proposed. The background underpinning this framework, including a research study of housing in self-neglect and interagency responses, is briefly outlined in this paper.

    The importance of the role model function of the 'teacher' (m/f) was always realized to some extent in practical clinical teaching, but appears to be gaining renewed interest at present. There exists, however, a discrepancy between the importance attached by many experienced clinicians and their students to the role model on the one hand, and the amount of systematical study that has been dedicated to it on the other hand. The available date show an impressionistic image of the qualities these students and interns consider important in role models. However, the 'why' of the importance of role models is seldom considered. In an era in which it is considered important that 'learning targets', 'learning moments' and 'transfer mechanisms' are defined in detail, the function of role models in practical clinical teaching should also be given more attention. Insights from other fields of knowledge than the medical field might be of value in designing research leading to a clearer image of the function and the value of role models in practical clinical education.

  12. Effect of land tenure and stakeholders attitudes on optimization of conservation practices in agricultural watersheds

    Modeled watershed management plans have become valuable tools for evaluating the effectiveness and impacts of conservation practices on hydrologic processes in watersheds. In multi-objective optimization approaches, several studies have focused on maximizing physical, ecological, or economic benefits of practices in a specific location, without considering the relationship between social systems and social attitudes on the overall optimality of the practice at that location. For example, objectives that have been commonly used in spatial optimization of practices are economic costs, sediment loads, nutrient loads and pesticide loads. Though the benefits derived from these objectives are generally oriented towards community preferences, they do not represent attitudes of landowners who might operate their land differently than their neighbors (e.g. farm their own land or rent the land to someone else) and might have different social/personal drivers that motivate them to adopt the practices. In addition, a distribution of such landowners could exist in the watershed, leading to spatially varying preferences to practices. In this study we evaluated the effect of three different land tenure types on the spatial-optimization of conservation practices. To perform the optimization, we used a uniform distribution of land tenure type and a spatially varying distribution of land tenure type. Our results show that for a typical Midwestern agricultural watershed, the most optimal solutions (i.e. highest benefits for minimum economic costs) found were for a uniform distribution of landowners who operate their own land. When a different land-tenure was used for the watershed, the optimized alternatives did not change significantly for nitrates reduction benefits and sediment reduction benefits, but were attained at economic costs much higher than the costs of the landowner who farms her/his own land. For example, landowners who rent to cash-renters would have to spend ~120

    In recent years, the use of laboratory animals has decreased as a result of the adoption of alternative methods such as in vitro experiments and simulation studies. Nonetheless, animal models continue to be necessary in many fields of biomedical research, giving rise to ethical issues regarding the treatment of these animals. In the present work, a general overview of the rules of good practise in caring for laboratory animals is provided, focussing on housing conditions and the proper means of handling animals, including the importance of the relationship or "bond" between the researcher and the animal.

    Temporal variation may influence the ability of best management practices (BMPs) to mitigate the loss of agricultural pollutants to streams. Our goal was to assess variation in mitigation effects of BMPs by examining the associations between instream nutrient concentrations and the abundance and location of four structural BMPs over a hydrologic year. Water samples were collected monthly (Nov. 2013-Oct. 2014) in 15 headwater streams representing a gradient of BMP use in Southern Ontario, Canada. Partial least squares (PLS) regression models were used to associate two groups of collinear nutrient forms with the abundance and location of BMPs, antecedent precipitation and time of year. BMP metrics in PLS models were associated with instream concentrations of major phosphorus forms and ammonium throughout the year. In contrast, total nitrogen and nitrate-nitrite were only associated with BMPs during snowmelt. BMP metrics associated with reductions of phosphorus and ammonium included greater abundances of riparian buffers and manure storage structures, but not livestock restriction fences. Likewise, the abundance and location riparian vegetation in areas capturing more surface runoff were associated with decreased stream nitrogen concentrations during snowmelt. However, the amount of tile drainage was associated with increased nitrogen concentrations following snowmelt, as well as with greater phosphorus and ammonium concentrations throughout the year. Overall, our findings indicate that increasing the abundance of riparian buffers and manure storage structures may decrease instream nutrient concentrations in agricultural areas. Additionally, the implementation of these structural BMPs appear to be an effective year-round strategy to assist management objectives in reducing phosphorus concentrations in small agricultural streams and thus loadings to downstream tributaries. Further mitigation measures, such as managerial BMPs and controlled tile drainage, may be

    Laboratory capacity in the developing world frequently lacks quality management systems (QMS) such as good clinical laboratory practices, proper safety precautions, and adequate facilities; impacting the ability to conduct biomedical research where it is needed most. As the regulatory climate changes globally, higher quality laboratory support is needed to protect study volunteers and to accurately assess biological parameters. The University of Bamako and its partners have undertaken a comprehensive QMS plan to improve quality and productivity using the Clinical and Laboratory Standards Institute standards and guidelines. The clinical laboratory passed the College of American Pathologists inspection in April 2010, and received full accreditation in June 2010. Our efforts to implement high-quality standards have been valuable for evaluating safety and immunogenicity of malaria vaccine candidates in Mali. Other disease-specific research groups in resource-limited settings may benefit by incorporating similar training initiatives, QMS methods, and continual improvement practices to ensure best practices.

    In recent years studies not falling under the German Pharmaceutical Law ("non-drug trials") have also been increasingly expected to be conducted according to Good Clinical Practice (GCP) in order to ensure that uniform standards are maintained for data quality and patient safety. However, simple transfer of the GCP criteria is not always possible and often not useful. Given the fact that research questions regarding non-drug interventions are common in primary care (e.g., general practice), the "Network for Clinical Studies in General Practice" has developed a manual for planning and conducting non-drug trials. This manual is based on the GCP guideline, taking account of the conditions and circumstances in primary care settings. Both structure and relevant content of the manual are presented in the article.

    One of the aims of 'The Bologna Process' is to promote among the students the acquisition of practical, social and creative skills to face real-life situations and to solve the difficulties they might find during their professional life. It involves an important change in the educational system, from a traditional approach focused on teaching, towards a new one that encourages learning. Under this context, University teaching implies the design of activities addressed to the dissemination of "know-how" to solve different problems associated with two technical disciplines: Forest and Agricultural Engineering. This study presents a preliminary experience where a group of information and communication technologies (ICT) such as, audiovisual resources (videos, reports and photo gallery), virtual visits to blogs and interactive activities have been used to provide a comprehensive knowledge of the environmental and sociocultural components of the landscape in order to facilitate the decision-making process in the engineering project context . With these tools, the students must study and characterize all these aspects in order to justify the chosen solutions and the project design. This approach was followed in the analysis of the limiting factors of practical cases in projects about forestation, landscape restoration and hydrological planning. This communication shows how this methodology has been applied in Forest and Agricultural Engineering and the students' experience with these innovative tools. The use of ICTs involved a friendly framework that stimulated students' interest and made subjects more attractive, since it allowed to assess the complex relationships between landscape, history and economy. Furthermore, this type of activities promotes the interdisciplinary training and the acquisition of creative and autonomous skills which are not included in many cases into the main objectives of the subjects.

    The composition and structure of bacterial communities were examined in soil subjected to a range of diverse agricultural land management and crop production practices. Length heterogeneity polymerase chain reaction (LH-PCR) of bacterial DNA extracted from soil was used to generate amplicon profiles that were analyzed with univariate and multivariate statistical methods. Five land management programs were initiated in July 2000: conventional, organic, continuous removal of vegetation (disk fallow), undisturbed (weed fallow), and bahiagrass pasture (Paspalum notatum var Argentine). Similar levels in the diversity of bacterial 16S rDNA amplicons were detected in soil samples collected from organically and conventionally managed plots 3 and 4 years after initiation of land management programs, whereas significantly lower levels of diversity were observed in samples collected from bahiagrass pasture. Differences in diversity were attributed to effects on how the relative abundance of individual amplicons were distributed (evenness) and not on the total numbers of bacterial 16S rDNA amplicons detected (richness). Similar levels of diversity were detected among all land management programs in soil samples collected after successive years of tomato (Lycopersicon esculentum) cultivation. A different trend was observed after a multivariate examination of the similarities in genetic composition among soil bacterial communities. After 3 years of land management, similarities in genetic composition of soil bacterial communities were observed in plots where disturbance was minimized (bahiagrass and weed fallow). The genetic compositions in plots managed organically were similar to each other and distinct from bacterial communities in other land management programs. After successive years of tomato cultivation and damage from two major hurricanes, only the composition of soil bacterial communities within organically managed plots continued to maintain a high degree of similarity

    - The application of fallout radionuclides (FRNs) in soil erosion and redistribution studies has gained popularity since the late 1980s. In Zimbabwe, soil erosion research was mostly based on conventional methods which included the use of erosion plots for quantitative measurements and erosion models for predicting soil losses. Only limited investigation to explore the possibility of using Caesium-137 (Cs-137) has been reported in the early 1990s for undisturbed and cultivated lands in Zimbabwe. In this study, the Cs-137 technique was applied to assess the impact of soil conservation practices on soil losses and to develop strategies and support effective policies that help farmers in Zimbabwe for sustainable land management. The study was carried out at the Makoholi research station 30 km north of the Masvingo region which is located 260 km south of Harare. The area is semi-arid and the study site comprises coarse loamy sands, gleyic lixisols. The conservation agriculture (CA) practices used within the area since 1988 include (i) direct seeding (DS) with mulch, (ii) CA basins with mulch, and (iii) 18 years direct seeding, left fallow for seven years and turned into conventional tillage since 2012 (DS/F/C). The Cs-137 reference inventory was established at 214 ± 16 Bq/m2. The mean inventories for DS, CA basins and DS/F/C were 195, 190 and 214 Bq/m2 respectively. Using the conversion Mass Balance Model 2 on the Cs-137 data obtained along transects for each of the practices, gross erosion rates were found to be 7.5, 7.3 and 2.6 t/ha/yr for direct seeding, CA basins and the DS/F/C while the net erosion rates were found to be 3.8, 4.6 and 0 t/ha/yr respectively. Sediment delivery ratios were 50%, 63% and 2% in the respective order. These preliminary results showed the effectiveness of DS over CA basins in erosion control. The efficiency of fallowing in controlling excessive soil loss was significant in the plot that started as DS for 18 years but left fallow for 7

    A clinician-reported outcome (ClinRO) assessment is a type of clinical outcome assessment (COA). ClinRO assessments, like all COAs (patient-reported, observer-reported, or performance outcome assessments), are used to 1) measure patients’ health status and 2) define end points that can be interpreted as treatment benefits of medical interventions on how patients feel, function, or survive in clinical trials. Like other COAs, ClinRO assessments can be influenced by human choices, judgment, or motivation. A ClinRO assessment is conducted and reported by a trained health care professional and requires specialized professional training to evaluate the patient’s health status. This is the second of two reports by the ISPOR Clinical Outcomes Assessment—Emerging Good Practices for Outcomes Research Task Force. The first report provided an overview of COAs including definitions important for an understanding of COA measurement practices. This report focuses specifically on issues related to ClinRO assessments. In this report, we define three types of ClinRO assessments (readings, ratings, and clinician global assessments) and describe emerging good measurement practices in their development and evaluation. The good measurement practices include 1) defining the context of use; 2) identifying the concept of interest measured; 3) defining the intended treatment benefit on how patients feel, function, or survive reflected by the ClinRO assessment and evaluating the relationship between that intended treatment benefit and the concept of interest; 4) documenting content validity; 5) evaluating other measurement properties once content validity is established (including intra- and inter-rater reliability); 6) defining study objectives and end point(s) objectives, and defining study end points and placing study end points within the hierarchy of end points; 7) establishing interpretability in trial results; and 8) evaluating operational considerations for the implementation

    The study of agricultural chemicals is one of five national priority topics being addressed by the National Water-Quality Assessment (NAWQA) Program in its second decade of studies, which began in 2001. Seven watersheds across the Nation were selected for the NAWQA agricultural-chemical topical study. The watersheds selected represent a range of agricultural settings - with varying crop types and agricultural practices related to tillage, irrigation, artificial drainage, and chemical use - as well as a range of landscapes with different geology, soils, topography, climate, and hydrology (Capel and others, 2004). Chemicals selected for study include nutrients (nitrogen and phosphorus) and about 50 commonly used pesticides. This study design leads to an improved understanding of many factors that can affect the movement of water and chemicals in different agricultural settings. Information from these studies will help with decision making related to chemical use, conservation, and other farming practices that are used to reduce runoff of agricultural chemicals and sediment from fields (Capel and others, 2004). This Fact Sheet highlights the results of the NAWQA agricultural chemical study in the Leary Weber Ditch Watershed in Hancock County, Indiana. This watershed was selected to represent a tile-drained, corn and soybean, humid area typical in the Midwest.

    Owing to increasing anthropogenic impacts, lagoons and wetlands are being exposed to environmental degradation. Therefore, the sustainable management of these environmental resources is a fundamental issue to maintain either the ecosystems and the human activity. The Massaciuccoli Lake is a coastal lake of fresh to brackish water surrounded by a marsh, which drains a total catchment of about 114 km2. Large part of the basin has been reclaimed since 1930 by means of pumping stations forcing water from the drained areas into the lake. The system is characterized by: high complexity of the hydrological setting; subsidence of the peaty soils in the reclaimed area (2 to 3 m in 70 years), that left the lake perched; reclaimed land currently devoted mainly to conventional agriculture (e.g.: maize monoculture) along with some industrial sites, two sewage treatment plants and some relevant urban settlements; social conflicts among different land users because of the impact on water quality and quantity. The interaction between such a fragile natural system and human activities leads to an altered ecological status mainly due to eutrophication and water salinisation. Hence, the present work aims at identifying and assessing the sources of nutrients (phosphorous in particular) into the lake, and characterising land use and some socio-economic aspects focusing on agricultural systems, in order to set up suitable mitigation measures. Water quantity and quality in the most intensively cultivated sub-catchment, placed 0.5 to 3 m under m.s.l. were monitored in order to underlain the interaction between water and its nutrient load. Questionnaires and interviews to farmers were conducted to obtain information about agricultural practices, farm management, risks and constraints for farming activities. The available information about the natural system and land use were collected and organised in a GIS system: a conceptual model of surface water hydrodinamics was build up and 14

    Over the last 35 years, there has been dramatic progress in the technology and applicability of percutaneous techniques to treat obstructive coronary heart disease. Percutaneous coronary intervention (PCI) has a considerable evidence base and it is firmly established as the most common procedure used in the invasive treatment of patients with coronary heart disease in the UK. This set of guidelines aims to address specifically issues relating to PCI and not the growing subspecialty of structural heart disease intervention. It is not intended to provide a review of the entire evidence base for coronary intervention. The evidence base relating to PCI is extensively reviewed in international guidelines and the British Cardiovascular Intervention society endorses these guidelines and their updates. The guidelines presented here focus on issues pertinent to practice within the UK and set out a recommended template to ensure optimal delivery of patient care. PMID:26041756

    This paper presents work using case studies as a source of data to see if we could extrapolate from the specific to the general particularly with regard to understanding what constitutes effective practice in taking action on SDHI and as a way of enabling policy makers to make better use of knowledge within the case studies and as a way of better understanding what works, in what context and why. Case studies are important to evaluators in that they are relatively straightforward to undertake and because those involved in implementing an intervention are usually keen to profile the intervention. A checklist described in this paper will enable policy advisers and evaluators to quickly review a case study and right away see if it contains enough information to assist in the development of policy options for reducing socially determined health inequalities.

    Background Studies have sought to define information needs of health workers within very specific settings or projects. Lacking in the literature is how hospitals in low-income settings are able to meet the information needs of their staff and the use of information communication technologies (ICT) in day-to-day information searching. Objective The study aimed to explore where professionals in Kenyan hospitals turn to for work-related information in their day-to-day work. Additionally, it examined what existing solutions are provided by hospitals with regard to provision of best practice care. Lastly, the study explored the use of ICT in information searching. Design Data for this study were collected in July 2012. Self-administered questionnaires (SAQs) were distributed across 22 study hospitals with an aim to get a response from 34 health workers per hospital. Results SAQs were collected from 657 health workers. The most popular sources of information to guide work were fellow health workers and printed guidelines while the least popular were scientific journals. Of value to health workers were: national treatment policies, new research findings, regular reports from surveillance data, information on costs of services and information on their performance of routine clinical tasks; however, hospitals only partially met these needs. Barriers to accessing information sources included: ‘not available/difficult to get’ and ‘difficult to understand’. ICT use for information seeking was reported and with demographic specific differences noted from the multivariate logistic regression model; nurses compared to medical doctors and older workers were less likely to use ICT for health information searching. Barriers to accessing Internet were identified as: high costs and the lack of the service at home or at work. Conclusions Hospitals need to provide appropriate information by improving information dissemination efforts and providing an enabling environment that

    Proper use of drugs can be defined as the use of the right product, in a correct dosage, during an adequate length of time, for a given patient and provided he has no serious side effects. It is virtually impossible, with such a number of drugs, such a number of clinical situations to prescribe adequately without using references or guidelines. References may lead to a unique choice, when the diagnosis is certain and the drug to be given is unique. With a good initial and continuous medical education, doctors can take easily this type of decision. The Summary of Products Characteristics (SPC) helps them; by sticking to this fundamental reference, prescription might be more precise and safe. In a lot of clinical situations the choice between a large numbers of therapeutic strategies necessitates use of a guideline based on scientific knowledge. Finally, a given therapeutic strategy can be as effective as and considerably less expensive than another. In such cases, payers can drive doctors to the prescription of the less expensive strategy. Some difficulties are common to all references and guidelines.

    Our aim was to document current communication and information-sharing practices and to identify the barriers and enablers to good practices within the context of care planning for chronic condition management. Further aims were to make recommendations about how changes to policy and practice can improve communication and information sharing in primary health care. A mixed-method approach was applied to seek the perspectives of patients and primary health-care workers across Australia. Data was collected via interviews, focus groups, non-participant observations and a national survey. Data analysis was performed using a mix of thematic, discourse and statistical approaches. Central barriers to effective communication and information sharing included fragmented communication, uncertainty around client and interagency consent, and the unacknowledged existence of overlapping care plans. To be most effective, communication and information sharing should be open, two-way and inclusive of all members of health-care teams. It must also only be undertaken with the appropriate participant consent, otherwise this has the potential to cause patients harm. Improvements in care planning as a communication and information-sharing tool may be achieved through practice initiatives that reflect the rhetoric of collaborative person-centred care, which is already supported through existing policy in Australia. General practitioners and other primary care providers should operationalise care planning, and the expectation of collaborative and effective communication of care that underpins it, within their practice with patients and all members of the care team. To assist in meeting these aims, we make several recommendations.

The analysis of the literature and our own work indicates that it is difficult to account for all the possible variables where research is used to inform land management practices. Assisting farmers to conduct localised research in cooperative ventures is likely to bring about the best outcomes where site-specific research directly informs land management practices. 1.

    There is compelling evidence to support the rationale for managing children on intravenous antimicrobial therapy at home whenever possible, including parent and patient satisfaction, psychological well-being, return to school/employment, reductions in healthcare-associated infection and cost savings. As a joint collaboration between the BSAC and the British Paediatric Allergy, Immunity and Infection Group, we have developed good practice recommendations to highlight good clinical practice and governance within paediatric outpatient parenteral antibiotic therapy (p-OPAT) services across the UK. These guidelines provide a practical approach for safely delivering a p-OPAT service in both secondary care and tertiary care settings, in terms of the roles and responsibilities of members of the p-OPAT team, the structure required to deliver the service, identifying patients and pathologies that are suitable for p-OPAT, ensuring appropriate vascular access, antimicrobial choice and delivery and the clinical governance aspects of delivering a p-OPAT service. The process of writing a business case to support the introduction of a p-OPAT service is also addressed.

    Chlorophyll fluorescence is a non-invasive measurement of photosystem II (PSII) activity and is a commonly used technique in plant physiology. The sensitivity of PSII activity to abiotic and biotic factors has made this a key technique not only for understanding the photosynthetic mechanisms but also as a broader indicator of how plants respond to environmental change. This, along with low cost and ease of collecting data, has resulted in the appearance of a large array of instrument types for measurement and calculated parameters which can be bewildering for the new user. Moreover, its accessibility can lead to misuse and misinterpretation when the underlying photosynthetic processes are not fully appreciated. This review is timely because it sits at a point of renewed interest in chlorophyll fluorescence where fast measurements of photosynthetic performance are now required for crop improvement purposes. Here we help the researcher make choices in terms of protocols using the equipment and expertise available, especially for field measurements. We start with a basic overview of the principles of fluorescence analysis and provide advice on best practice for taking pulse amplitude-modulated measurements. We also discuss a number of emerging techniques for contemporary crop and ecology research, where we see continual development and application of analytical techniques to meet the new challenges that have arisen in recent years. We end the review by briefly discussing the emerging area of monitoring fluorescence, chlorophyll fluorescence imaging, field phenotyping, and remote sensing of crops for yield and biomass enhancement.

  13. The good, the bad and the 'not so bad': reflecting on moral appraisal in practice.

    PubMed

    Begley, Ann Marie

    2011-03-01

    The aim of this study is to facilitate reflection on the moral merit of practitioners in various contexts. Insight is gained from Aristotelian and Kantian accounts of moral character and an original framework for reflection is presented as an adjunct to ethical theory and principles considered when appraising others. In relation to states of character, there is an irreconcilable difference between Kantian (deontic) and Aristotelian (aretaic) conceptions of the nature of full virtue (excellence of character), but at the same time it can be argued that in relation to practice their approaches complement each other. It is also argued that in relation to caring for the vulnerable, Aristotle's conception of full virtue is more compelling than Kant's. On the other hand, Kant's notion of self-serving action is important in nursing and it therefore needs to be considered when reflecting on professional conduct. The conclusion reached is that Aristotelian and Kantian accounts of character appraisal should be used in a combined approach to moral appraisal. This approach draws on the accounts of both philosophers and offers valuable insight into moral character, professional conduct and, in a more formal setting, fitness to practise.

    Agricultural practices have proven to be unsuitable in many cases, causing considerable reductions in soil quality. Land management practices can provide solutions to this problem and contribute to get a sustainable agriculture model. The main objective of this work was to assess the effect of different agricultural management practices on soil microbial community structure (evaluated as abundance of phospholipid fatty acids, PLFA). Five different treatments were selected, based on the most common practices used by farmers in the study area (eastern Spain): residual herbicides, tillage, tillage with oats and oats straw mulching; these agricultural practices were evaluated against an abandoned land after farming and an adjacent long term wild forest coverage. The results showed a substantial level of differentiation in the microbial community structure, in terms of management practices, which was highly associated with soil organic matter content. Addition of oats straw led to a microbial community structure closer to wild forest coverage soil, associated with increases in organic carbon, microbial biomass and fungal abundances. The microbial community composition of the abandoned agricultural soil was characterised by increases in both fungal abundances and the metabolic quotient (soil respiration per unit of microbial biomass), suggesting an increase in the stability of organic carbon. The ratio of bacteria:fungi was higher in wild forest coverage and land abandoned systems, as well as in the soil treated with oat straw. The most intensively managed soils showed higher abundances of bacteria and actinobacteria. Thus, the application of organic matter, such as oats straw, appears to be a sustainable management practice that enhances organic carbon, microbial biomass and activity and fungal abundances, thereby changing the microbial community structure to one more similar to those observed in soils under wild forest coverage.

    A two - year plant - based soil clean - up was carried out at a crude oil spill agricultural site in a Niger Delta community in Nigeria to access further clean - up potentials of Cymbopogon citratus. Applied diagnostic ratios identified mixed petrogenic and pyrogenic sources as the main contributors of PAHs. Up to 90.8% sequestration was obtained for carcinogenic PAHs especially Benz (a) pyrene in a 2 - phase manner. A community level approach for assessing patterns of sole carbon source utilization by mixed microbial samples was employed to differentiate spatial and temporal changes in the soil microbial communities. In relation to pollution, soil conditioning notably decreased the lag times and showed mixed effects for colour development rates, maximum absorbance and the overall community pattern. For rate and utilization of different carbon substrates in BIOLOG wells, after day 3, in comparison to control soil communities, contamination with hydrocarbons and associated types increased amines and amides consumption. Consumption of carbohydrates in all polluted and unamended regimes decreased markedlyin comparison to those cultivated with C. citratus. We found a direct relationship between cellulose breakdown, measurable with B-glucosidase activity, organic matter content and CO2 realease within all soils in the present study. Organic amendment rendered most studied contaminants unavailable for uptake in preference to inorganic fertilizer in both study years. Generally, phytoremediation improved significantly the microbial community activity and thus would promote ecosystem restoration in relation to most patronised techniques. Supplementation with required nutrients, in a long - term design would present many ecological benefits. Keywords: Agricultural soils; Recovery; Hydrocarbon pollution; Ecology; Management practice.

    Preserving ecosystem functions of soil organic matter (SOM) in soils is a key challenge. The need for an efficient diagnosis of SOM state in agricultural soils is a priority in order to facilitate the detection of changes in soil quality as a result of changes in management practices. The nature of SOM is complex and cannot readily be monitored due to the heterogeneity of its components. Assessment of the SOM level dynamics, typically characterized as the bulk soil organic carbon (SOC), can be refined by taking into account carbon pools with different turnover rates and stability. Fractionating bulk SOC in meaningful soil organic fractions helps to better diagnose SOC status. By separating carbon associated with clay and fine silt particles (stable carbon with slow turnover rate) and carbon non-associated with this fraction (labile and intermediate carbon with higher turnover rates), effects of management can be detected more efficiently at different spatial and temporal scales. Until now, most work on SOC fractionation has focused on small spatial scales along management or time gradients. The present case study focuses on SOC fractionation applied in order to refine the interpretation of organic matter turnover and SOC sequestration for regional units in Wallonia with comparable climate, management and, to a certain extent, soil conditions. In each unit, random samples from specific land uses are analyzed in order to assess the Normal Operative Ranges (NOR) of SOC fraction contents for each unit and land use combination. Thus, SOC levels of the different fractions of a specific field in a given unit can be compared to its corresponding NOR. It will help to better diagnose agricultural soil quality in terms of organic carbon compared to a bulk SOC diagnosis.

    There is a significant and growing interest among both payers and producers of medical products for agreements that involve a "pay-for-performance" or "risk-sharing" element. These payment schemes-called "performance-based risk-sharing arrangements" (PBRSAs)-involve a plan by which the performance of the product is tracked in a defined patient population over a specified period of time and the amount or level of reimbursement is based on the health and cost outcomes achieved. There has always been considerable uncertainty at product launch about the ultimate real-world clinical and economic performance of new products, but this appears to have increased in recent years. PBRSAs represent one mechanism for reducing this uncertainty through greater investment in evidence collection while a technology is used within a health care system. The objective of this Task Force report was to set out the standards that should be applied to "good practices"-both research and operational-in the use of a PBRSA, encompassing questions around the desirability, design, implementation, and evaluation of such an arrangement. This report provides practical recommendations for the development and application of state-of-the-art methods to be used when considering, using, or reviewing PBRSAs. Key findings and recommendations include the following. Additional evidence collection is costly, and there are numerous barriers to establishing viable and cost-effective PBRSAs: negotiation, monitoring, and evaluation costs can be substantial. For good research practice in PBRSAs, it is critical to match the appropriate study and research design to the uncertainties being addressed. Good governance processes are also essential. The information generated as part of PBRSAs has public good aspects, bringing ethical and professional obligations, which need to be considered from a policy perspective. The societal desirability of a particular PBRSA is fundamentally an issue as to whether the cost of

    These good practice recommendations for outpatient parenteral antimicrobial therapy (OPAT) are an update to a previous consensus statement on OPAT in the UK published in 1998. They are based on previous national and international guidelines, but have been further developed through an extensive consultation process, and are underpinned by evidence from published literature on OPAT. They provide pragmatic guidance on the development and delivery of OPAT services, looking at all aspects of service design, care delivery, outcome monitoring and quality assurance, with the aim of ensuring that OPAT services provide high-quality, low-risk care, whatever the healthcare setting. They will provide a useful resource for teams developing new services, as well as a practical set of quality indicators for existing services.

    2006-08-01

    In recent years, improvements in point-source depuration technologies have highlighted the problems regarding agricultural nonpoint (diffuse) sources, and this issue has become highly relevant from the environmental point of view. The considerable extension of the areas responsible for this kind of pollution, together with the scarcity of funds available to local managers, make minimizing the impacts of nonpoint sources on a whole basin a virtually impossible task. This article presents the results of a study intended to pinpoint those agricultural areas, within a basin, that contribute most to water pollution, so that operations aimed at preventing and/or reducing this kind of pollution can be focused on them. With this aim, an innovative approach is presented that integrates a field-scale management model, a simple regression model, and a geographic information system (GIS). The Lake Vico basin, where recent studies highlighted a considerable increase in the trophic state, mainly caused by phosphorus (P) compounds deriving principally from the intensive cultivation of hazelnut trees in the lake basin, was chosen as the study site. Using the management model Groundwater Loading Effects of Agricultural Management Systems (GLEAMS), the consequences, in terms of sediment yield and phosphorus export, of hazelnut tree cultivation were estimated on different areas of the basin with and without the application of a best management practice (BMP) that consists of growing meadow under the trees. The GLEAMS results were successively extended to basin scale thanks to the application of a purposely designed regression model and of a GIS. The main conclusions can be summarized as follows: The effectiveness of the above-mentioned BMP is always greater for erosion reduction than for particulate P reduction, whatever the slope value considered; moreover, the effectiveness with reference to both particulate P and sediment yield production decreases as the slope increases.

Climate change has been recognized as the result of release of stored energy in fossil fuel into the atmosphere. Homogeneous crop varieties, machinery, pesticides and fertilizers are the foundation of uniform commodities in modern agriculture. Fossil fuels are used to manufacture fertilizers and pesticides as well as the energy source for agricultural machinery, thus characterizes modern agriculture. Bio-fuel production and the possibility of the agriculture system as a form of energy input are discussed.

    Empirical research shows that good waste management practice in South Africa is not always under the volitional control of those tasked with its implementation. While intention to act may exist, external factors, within the distal and proximal context, create barriers to waste behaviour. In addition, these barriers differ for respondents in municipalities, private industry and private waste companies. The main barriers to implementing good waste management practice experienced by respondents in municipalities included insufficient funding for waste management and resultant lack of resources; insufficient waste knowledge; political interference in decision-making; a slow decision-making process; lack of perceived authority to act by waste staff; and a low priority afforded to waste. Barriers experienced by respondents in private industry included insufficient funding for waste and the resultant lack of resources; insufficient waste knowledge; and government bureaucracy. Whereas, barriers experienced in private waste companies included increasing costs; government bureaucracy; global markets; and availability of waste for recycling. The results suggest that respondents in public and private waste organizations are subject to different structural forces that shape, enable and constrain waste behaviour.

  9. Utilization of the seven principles for good practice in undergraduate education in general chemistry by community college instructors

    In recent years, higher education has undergone many changes. The advent of assessment, accountability, and a newfound focus on teaching have required faculty to examine how they are teaching. Administrators and faculty are beginning to recognize that learning is not a "one size fits all" enterprise. To this end, Chickering and Gamson developed an inventory that examined faculty utilization of the Seven Principles of Good Practice in Undergraduate Education. The seven principles included by the authors included faculty-student interaction, cooperative learning, active learning, giving prompt feedback, emphasizing time on task, communicating high expectations, and respecting diverse talents and ways of learning. It was determined by Chickering and Gamson, as well as many other researchers, that these seven principles were hallmarks of successful undergraduate education. Community colleges are important institutions to study, as many students begin their higher education at two-year colleges. Most students are also required to take one or more science classes for their general education requirements; therefore, many students must take at least one general chemistry course. Both community colleges and chemistry are rarely studied in literature, which makes this study important. Community college general chemistry instructors were surveyed using an online version of Chickering and Gamson's Faculty Inventory for the Seven Principles of Good Practice in Undergraduate Education. Responses were analyzed, and it was discovered that not only did instructors utilize the principles to a different extent, but there were also differences between genders as well as between the specific actions related to each principle.

    The ever-increasing concern for the welfare of volunteers participating in clinical trials and for the integrity of the data derived from those trials has generated the concept of Good Clinical Practice (GCP). The Veterans Affairs Cooperative Studies Program, in anticipation of the need to comply with GCP guidelines, developed a Site Monitoring and Review Team (SMART), which consists of a Good Clinical Practice Monitoring Group and a Good Clinical Practice Review Group. The review group conducted 335 site reviews from fiscal years (FY) 1999 through 2001 to assess and encourage adherence to GCP. Data from reviews were compared for two time periods, a 2-year implementation period (FYs 1999/2000, n=204) and a continuing follow-up period (FY 2001, n=131). Overall, high GCP adherence was exhibited by 11.3% (n=23) of study sites in FY 1999/2000 versus 20.6% (n=27) in FY 2001, average to good adherence was exhibited by 84.3% (n=172) in FY 1999/2000 versus 77.0% (n=101) in FY 2001, and below average adherence was exhibited by 4.4% (n=9) versus 1.5% (n=3) in these two periods. These changes were statistically significant by chi square analysis (p=0.029). Moreover, GCP adherence was assessed within eight GCP focus areas: patient informed consent, protocol adherence, safety monitoring, institutional review board interactions, regulatory document management, patient records in investigator file, drug/device accountability, and general site operations. Median assessment scores for all 62 GCP review elements improved from 0.82 to 0.89 (p<0.001). Median assessment scores for the 14 selected critical GCP items improved from 0.78 to 0.89 (p<0.001). Median scores for five of the eight GCP focus areas improved significantly (p<0.001) between the two time periods. These data suggest that the site-oriented activities of SMART combined with centralized quality assurance activities of the coordinating centers represent an integrated, versatile program to promote and assure GCP adherence

    European rabbits (Oryctolagus cuniculus) pose a major threat to agricultural production and conservation values in several countries. In New Zealand, population control via poisoning is a frontline method for limiting rabbit damage, with large areas commonly treated using the metabolic toxin sodium fluoroacetate (‘1080’) delivered in bait via aerial dispersal. However, this method is expensive and the high application rates of the active ingredient cause public antipathy towards it. To guide reductions in cost and toxin usage, we evaluated the economics and efficacy of rabbit control using an experimental approach of sowing 1080-bait in strips instead of the commonly-used broadcast sowing method (i.e. complete coverage). Over a 4-year period we studied aerial delivery of 0.02% 1080 on diced carrot bait over ~3500 ha of rabbit-prone land in the North and South islands. In each case, experimental sowing via strip patterns using 10–15 kg of bait per hectare was compared with the current best practice of aerial broadcast sowing at 30–35 kg/ha. Operational kill rates exceeded 87% in all but one case and averaged 93–94% across a total of 19 treatment replicates under comparable conditions; there was no statistical difference in overall efficacy observed between the two sowing methods. We project that strip-sowing could reduce by two thirds the amount of active 1080 applied per hectare in aerial control operations against rabbits, both reducing the non-target poisoning risk and promoting cost savings to farming operations. These results indicate that, similarly to the recently-highlighted benefits of adopting strip-sowing for poison control of introduced brushtail possums (Trichosurus vulpecula) in New Zealand, aerial strip-sowing of toxic bait could also be considered a best practice method for rabbit control in pest control policy.

    To study the effects of agricultural practices on the groundwater quality of the Inner Bluegrass Region of Kentucky, a large representative row crop and livestock production operation was chosen. Located in southeastern Bourbon County, the study area encompasses a 1,400 acre watershed underlain by limestones and shales of the Ordovician age Lexington Limestone Formation. Sampling and testing of surface water, ephemeral, and perennial spring waters began in the area in October, 1989. At crop and pasture micro-sites within the study area, nests containing porous-cup lysimeters and monitoring wells were installed prior to the 1992 growing season. Samples from the nest locations were analyzed for Nitrate-N, triazines, metolochlor, carbofuran, alachlor, and 2,4-D. While only ten per cent of the total samples from the study area showed triazine or Nitrate-N concentrations in excess of EPA limits, greater than 80 per cent of the samples showed concentrations of triazines above detection limits, and greater than 70 per cent of the samples contained concentrations of Nitrate-N above detection limits. Occurrences of detectable concentrations of triazines and Nitrate-N were more frequent at crop-site nests, than at pasture-site nests. Nests at both the crop and pasture sites indicated dilution of Nitrate-N and triazine concentrations with depth.

    The purpose of this study was to describe current safety practices and risk awareness associated with confined spaces in agriculture among Utah farm owner/operators. There were 399 farm owner/operators in the sample. The final response rate was 82.2%. The typical farm owner/operator in this study was male, between the ages of 50 and 59, with some education beyond high school. Grain and dairy production comprised 48.7% of the operations responding to the survey. A majority (50.2%) of respondents reported having entered a confined space without an observer waiting from the outside. All but 9.5% of the respondents indicated that they had no written emergency response plan in the event of a confined space emergency involving an entrant. Only 49.1% of farm owner/operators perceived entering a grain bin while unloading as a high risk for fatal injury. More research is needed to determine the farmers' knowledge of the variety of hazards associated with confined space work. Few farm owner/operators reported using accessible safety equipment. A limited number of respondents indicated having access to gas monitors, lifeline and harness systems, or ventilation blowers with flexible ducting. This may be associated with the costs of the equipment, or lack of awareness of the need for specific safety equipment.

    Implementing the concept of sustainability through integrated approaches to natural resource management poses enormous challenges for both the rural communities and government agencies concerned. This paper reviews the underlying rhetoric of sustainable agricultural systems and the integrated resource management paradigm and identifies some of the challenges being experienced in translating this rhetoric into practice. A relatively recently implemented community-based integrated catchment management (ICM) process in a rural community in northeast Australia is examined in terms of some of the lessons learned that may be relevant to other similar integrated resource management (IRM) processes. It reveals a pragmatic, opportunistic, and evolving implementation process based on adaptive learning rather than a more traditional rational planning approach. Some essential characteristics of a community-based IRM process are identified, including fostering communication; providing a structure that fosters cooperation and facilities coordination among community, industry, and government agencies; the integration of IRM principles into local government planning schemes; and an emergent strategic approach to IRM program implementation. The authors conclude by identifying some essential characteristics of an IRM process that can assist a community to adapt to, and manage change for, sustainable resource use.

    Farming transformed societies globally. Yet, despite more than a century of research, there is little consensus on the speed or completeness of this fundamental change and, consequently, on its principal drivers. For Northern Europe, the debate has often centered on the rich archaeological record of the Western Baltic, but even here it is unclear how quickly or completely people abandoned wild terrestrial and marine resources after the introduction of domesticated plants and animals at ∼4000 calibrated years B.C. Ceramic containers are found ubiquitously on these sites and contain remarkably well-preserved lipids derived from the original use of the vessel. Reconstructing culinary practices from this ceramic record can contribute to longstanding debates concerning the origins of farming. Here we present data on the molecular and isotopic characteristics of lipids extracted from 133 ceramic vessels and 100 carbonized surface residues dating to immediately before and after the first evidence of domesticated animals and plants in the Western Baltic. The presence of specific lipid biomarkers, notably ω-(o-alkylphenyl)alkanoic acids, and the isotopic composition of individual n-alkanoic acids clearly show that a significant proportion (∼20%) of ceramic vessels with lipids preserved continued to be used for processing marine and freshwater resources across the transition to agriculture in this region. Although changes in pottery use are immediately evident, our data challenge the popular notions that economies were completely transformed with the arrival of farming and that Neolithic pottery was exclusively associated with produce from domesticated animals and plants.

    Crop yields are largely determined by climate variations and agricultural management practices, such as irrigation, fertilization and residue management. Understanding the role of these factors in regulating crop yield variations is not only important for improved crop yield production, but also equally valuable for future crop yield prediction and food security assessments. Recently, the Community Land Model (CLM) has been augmented and evaluated for simulating corn, soybean and cereals at coarse aerial resolutions of 2 degrees (2000x2000 km). To better understand the underlying mechanisms controlling yield variations, we implemented and validated the agricultural version of CLM (CLM-crop) at a 0.125 degree resolution over the Conterminous United States (CONUS). We conducted a suite of numerical experiments to untangle the relative influence of climatic variations (temperature, precipitation, and radiation) and agricultural management practices on yield variations for the past 30 years at the US county level. Preliminary results show that the model with default parameter settings captures well the temporal variations in crop yields, as compared with the actual yield reported by the US Department of Agriculture (USDA). However, the magnitude of simulated crop yields is substantially higher, especially in the Mid-western US. We find that improved characterization of fertilizers and irrigation practices is key to model performance. Retrospectively (1979-2012), crop yields are more sensitive to changes in climate factors (such as temperature) than to changes in crop management practices. The results of this study advances understanding of the dominant factors in regulating the crop yield variations at the county level, which is essential for credible prediction of crop yields in a changing climate, under different agricultural management practices.

    The arbuscular mycorrhizal fungi (AMF) are a key, integral component of the stability, sustainability and functioning of ecosystems. In this study a field experiment was performed at the El Teularet-Sierra de Enguera Experimental Station (eastern Spain) to assess the influence during a 6-yr period of different agricultural practices on the diversity of arbuscular mycorrhizal fungi (AMF). The management practices included residual herbicide use, ploughing, ploughing + oats, addition of oat straw mulch and a control (land abandonment). Adjacent soil under natural vegetation was used as a reference for local, high-quality soil and as a control for comparison with the agricultural soils under different management practices. The AM fungal small-subunit (SSU) rRNA genes were subjected to PCR, cloning, sequencing and phylogenetic analyses. Thirty-six different phylotypes were identified, which were grouped in four families: Glomeraceae, Paraglomeraceae, Ambisporaceae and Claroideoglomeraceae. The first results showed significant differences in the distribution of the AMF phylotypes as consequence of the difference between agricultural management practices. Thus, the lowest diversity was observed for the plot that was treated with herbicide. The management practices including ploughing and ploughing + oats had similar AMF diversity. Oat straw mulching yielded the highest number of different AMF sequence types and showed the highest diversity index. Thus, this treatment could be more suitable in sustainable soil use and therefore protection of biodiversity.

    2010-09-01

    In this qualitative study with three ethnocultural groups in two regions of Canada, we explore how official dietary guidelines provide particular standards concerning 'healthy eating' that marginalize other understandings of the relationship between food and health. In families where parents and youth held shared ways of understanding healthy eating, the role of 'good mother' was constructed so as to include healthy eating expertise. Mothers expressed a perceived need to be personally responsible for providing skills and knowledge about healthy eating as well as guarding children against negative nutritional influences. Governing of family eating practices to conform to official nutritional advice occurred through information provision, monitoring in shopping and meal preparation, restricting and guiding food purchases, and directly translating expert knowledges into family food practices. In families where parents and youth held differing understandings of healthy eating, primarily families from ethnocultural minority groups, mothers often did not employ the particular western-originating strategies of conveying healthy eating information, or mentoring healthy meal preparation, nor did they regulate or restrict children's food consumption. Western dietary guidelines entered into the family primarily through the youth, emphasizing the nutritional properties of food, often devaluing 'traditional' knowledge about healthy eating. These processes exemplify techniques of governmentality which simultaneously exercise control over people's behaviour through normalizing some family food practices and marginalizing others.

  1. Linking agricultural practices, mycorrhizal fungi, and traits mediating plant-insect interactions.

    Agricultural management has profound effects on soil communities. Activities such as fertilizer inputs can modify the composition of arbuscular mycorrhizal fungi (AMF) communities, which form important symbioses with the roots of most crop plants. Intensive conventional agricultural management may select for less mutualistic AMF with reduced benefits to host plants compared to organic management, but these differences are poorly understood. AMF are generally evaluated based on their direct growth effects on plants. However, mycorrhizal colonization also may alter plant traits such as tissue nutrients, defensive chemistry, or floral traits, which mediate important plant-insect interactions like herbivory and pollination. To determine the effect of AMF from different farming practices on plant performance and traits that putatively mediate species interactions, we performed a greenhouse study by inoculating Cucumis sativus (cucumber, Cucurbitaceae) with AMF from conventional farms, organic farms, and a commercial AMF inoculum. We measured growth and a suite of plant traits hypothesized to be important predictors of herbivore resistance and pollinator attraction. Several leaf and root traits and flower production were significantly affected by AMF inoculum. Both conventional and organic AMF reduced leaf P content but increased Na content compared to control and commercial AMF. Leaf defenses were unaffected by AMF treatments, but conventional AMF increased root cucurbitacin C, the primary defensive chemical of C. sativus, compared to organic AMF. These effects may have important consequences for herbivore preference and population dynamics. AMF from both organic and conventional farms decreased flower production relative to commercial and control treatments, which may reduce pollinator attraction and plant reproduction. AMF from both farm types also reduced seed germination, but effects on plant growth were limited. Our results suggest that studies only considering AMF

    Quality assurance is an indispensable element in a molecular diagnostic laboratory. The ultimate goal is to warrant patient safety. Several risks that can compromise high quality procedures are at stake, from sample collection to the test performed by the laboratory, the reporting of test results to clinicians, and the organization of effective external quality assessment schemes. Quality assurance should therefore be safeguarded at each level and should imply a holistic multidisciplinary approach. This review aims to provide an overview of good quality assurance practices and discusses certain risks and recommendations to promote and improve quality assurance for both diagnostic laboratories and for external quality assessment providers. The number of molecular targets is continuously rising, and new technologies are evolving. As this poses challenges for clinical implementation and increases the demand for external quality assessment, the formation of an international association for improving quality assurance in molecular pathology is called for.

    Faced with society's increasing expectations, the Common Agricultural Policy (CAP) review considers environmental management to be an ever more critical criterion in the allocation of farm subsidies. With the goal of evaluating the environmental friendliness of farm practices, France's agricultural research and extension services have built a range of agricultural/environmental diagnostic tools over recent years. The objective of the present paper is to compare the five tools most frequently used in France: IDEA, DIAGE, DIALECTE, DIALOGUE and INDIGO. All the tools have the same purpose: evaluation of the impact of farm practices on the environment via indicators and monitoring of farm management practices. When tested on a sample of large-scale farms in Picardie, the five tools sometimes produced completely different results: for a given farm, the most supposedly significant environmental impacts depend on the tool used. These results lead to differing environmental management plans and raise the question of the methods' pertinence. An analysis grid of diagnostic tools aimed at specifying their field of validity, limits and relevance was drawn up. The resulting comparative analysis enables to define each tool's domain of validity and allows to suggest lines of thought for developing more relevant tools for (i) evaluating a farm's environmental performance and (ii) helping farmers to develop a plan for improving practices within the framework of an environmental management system.

    Ecological changes associated with anthropogenic ecosystem disturbances can influence human risk of exposure to malaria and other vector-borne infectious diseases. This study in Mwea, Kenya, investigated the pattern of insecticide use in irrigated and nonirrigated agroecosystems and association with the density, survival, and blood-feeding behavior of the malaria vector Anopheles arabiensis. The parity rates of adult An. arabiensis from randomly selected houses were determined by examining their ovaries for tracheal distension, and polymerase chain reaction was used to identify the host blood meals. In addition, structured questionnaires were used to generate data on insecticide use. Anopheles arabiensis densities were highest in irrigated rice agroecosystems, intermediate in irrigated French beans agroecosystems, and lowest in the nonirrigated agroecosystem. Anopheles arabiensis adult survivorship was significantly lower in irrigated rice agroecosystems than in irrigated French beans agroecosystems. The human blood index (HBI) was significantly higher in the nonirrigated agroecosystem compared to irrigated agroecosystems. Moreover, there was marked variation in HBI among villages in irrigated agroecosystems with significantly lower HBI in Kangichiri and Mathangauta compared to Kiuria, Karima, and Kangai. The proportion of mosquitoes with mixed blood meals varied among villages ranging from 0.25 in Kangichiri to 0.83 in Kiuria. Sumithion, dimethoate, and alpha cypermethrin were the most commonly used insecticides. The 1st was used mostly in irrigated rice agroecosystems, and the last 2 were used mostly in irrigated French beans agroecosystems. These findings indicate that agricultural practices may influence the ecology and behavior of malaria vectors and ultimately the risk of malaria transmission.

    The Soil and Water Assessment Tool (SWAT) was used to assess the impact of agricultural best management practices (BMPs) on sediment runoff from almond orchards in the lower Colusa Basin Drain watershed in the Sacramento Valley, California. This study used modeling techniques that include varying hydrologic parameters for both upland areas and small channels to quantify the effects of BMPs water quality. The BMPs simulated in this study are commonly used in almond orchards and include strip cropping, cover cropping, vegetative filter strips, grassed waterways and channel stabilization. The effectiveness of each BMP was simulated for an above average, below average and average rainfall year. Comparison of annual total watershed sediment loads for each BMP simulation showed that overall, channel stabilization and grassed waterways, which target in stream sediment erosion and transport, are the most effective BMPs with an estimated respective reduction in sediment load of 18% and 35% for a below average precipitation year, 13% and 26% for an above average precipitation year, and 17% and 30% for an average precipitation year. Simulations of BMPs designed to reduce sediment transport in upland areas, which include strip cropping and vegetative filter strips, estimated a reduction in total annual sediment load of less than 1% at the watershed outlet. These results indicated that in-stream sediment transport is the dominant sediment transport process in this watershed. Implementation of channel stabilization measures or grassed waterways on almond orchards is estimated to result in an annual reduction of total sediment load of 41,874 kg or 72,753 kg of sediment per square kilometer of almond orchard for an above average precipitation year.

    Nebraska's Central Platte River Valley (CPRV) is a major spring-staging area for migratory birds. Over 6 million ducks, geese, and sandhill cranes (Grus canadensis) stage there en route to tundra, boreal forest, and prairie breeding habitats, storing nutrients for migration and reproduction by consuming primarily corn remaining in fields after harvest (hereafter residual corn). In springs 2005-2007, we measured residual corn density in randomly selected harvested cornfields during early (n=188) and late migration (n=143) periods. We estimated the mean density of residual corn for the CPRV and examined the influence of agricultural practices (post-harvest field management) and migration period on residual corn density. During the early migration period, residual corn density was greater in idle harvested fields than any other treatments of fields (42%, 48%, 53%, and 92% more than grazed, grazed and mulched, mulched, and tilled fields, respectively). Depletion of residual corn from early to late migration did not differ among post-harvest treatments but was greatest during the year when overall corn density was lowest (2006). Geometric mean early-migration residual corn density for the CPRV in 2005-2007 (42.4 kg/ha; 95% CI=35.2-51.5 kg/ha) was markedly lower than previously published estimates, indicating that there has been a decrease in abundance of residual corn available to waterfowl during spring staging. Increases in harvest efficiency have been implicated as a cause for decreasing corn densities since the 1970s. However, our data show that post-harvest management of cornfields also can substantially influence the density of residual corn remaining in fields during spring migration. Thus, managers may be able to influence abundance of high-energy foods for spring-staging migratory birds in the CPRV through programs that influence post-harvest management of cornfields. ?? 2011 The Wildlife Society.

    Conceptions of agricultural water security are conditioned by larger understandings of being and reality. It is still unclear what such understandings mean for perspectives on water security in general and on causes and solutions related to perceived water security risks and problems in agricultural sector in particular. Based on a systematic literature review, three conceptualizations of water security, related to different paradigms, are presented. Also the consequences of such conceptualizations for determining research objectives, research activities, and research outcomes on agricultural water security are discussed. The results showed that agricultural water security from a positivist paradigm referred to tangible and measurable water-related hazards and threats, such as floods and droughts, pollution, and so forth. A constructivist approach to agricultural water security, constituted by a process of interaction and negotiation, pointed at perceptions of water security of farmers and other stakeholders involved in agricultural sector. A critical approach to agricultural water security focused on the processes of securing vulnerable farmers and others from wider political, social, and natural impediments to sufficient water supplies. The conclusions of the study suggest that paradigms, underlying approaches should be expressed, clarified, and related to one another in order to find optimal and complementary ways to study water security issues in agricultural sector.

    In 2005, WHO Europe reconfirmed the objective of eradicating measles and fixed a strategy plan for the years 2005 up to 2010. While a downward trend of measles infections in Germany between 2001 and 2004 could be observed, as many as 780 cases of measles were reported in 2005 and in 2006 even 2.281 cases. These high figures in 2006 were almost exclusively caused by an outbreak in the German region of North Rhine-Westphalia. This case study describes how a reference framework for good health management of measles prevention was applied for this region. As a result, various recommendations for action could be given, among them the recommendation to implement individual vaccination reminder systems for parents and bonus systems for parents. Based on these results, a comprehensive policy concept has been drawn up and has become the subject of a political agreement process in this region. Thus this case study shows a paradigm how reference frameworks for good health management can be utilised in practice.

    Mercury (Hg) levels are alarmingly high in fish from lakes across Fennoscandia and northern North America. The few published studies on the ways in which silviculture practices influence this problem indicate that forest operations increase Hg in downstream aquatic ecosystems. From these studies, we estimate that between one-tenth and one-quarter of the Hg in the fish of high-latitude, managed forest landscapes can be attributed to harvesting. Forestry, however, did not create the elevated Hg levels in the soils, and waterborne Hg/MeHg concentrations downstream from harvested areas are similar to those from wetlands. Given the current understanding of the way in which silviculture impacts Hg cycling, most of the recommendations for good forest practice in Sweden appear to be appropriate for high-latitude regions, e.g., leaving riparian buffer zones, as well as reducing disturbance at stream crossings and in moist areas. The recommendation to restore wetlands and reduce drainage, however, will likely increase Hg/MeHg loadings to aquatic ecosystems.

    The EQAPOL contract was awarded to Duke University to develop and manage global proficiency testing programs for flow cytometry-, ELISpot-, and Luminex bead-based assays (cytokine analytes), as well as create a genetically diverse panel of HIV-1 viral cultures to be made available to National Institutes of Health (NIH) researchers. As a part of this contract, EQAPOL was required to operate under Good Clinical Laboratory Practices (GCLP) that are traditionally used for laboratories conducting endpoint assays for human clinical trials. EQAPOL adapted these guidelines to the management of proficiency testing programs while simultaneously incorporating aspects of ISO/IEC 17043 which are specifically designed for external proficiency management. Over the first two years of the contract, the EQAPOL Oversight Laboratories received training, developed standard operating procedures and quality management practices, implemented strict quality control procedures for equipment, reagents, and documentation, and received audits from the EQAPOL Central Quality Assurance Unit. GCLP programs, such as EQAPOL, strengthen a laboratory's ability to perform critical assays and provide quality assessments of future potential vaccines.

    Conservation tillage including zero and reduced tillage, crop rotation and upstream reservoirs are commonly implemented as beneficial management practices (BMPs) in the Canadian Prairies. However, their effects are strongly dependent on interactions with cold region hydrological processes, such as wind redistribution of snow, snowmelt, infiltration to frozen soils and evaporation, due to strong coupling between land surface characteristics and hydrology. These interactions are poorly understood and few studies have investigated them using a physically-based modeling framework. In this study, we deploy a physically-based, semi-distributed cold regions hydrological model (CRHM) to investigate the impacts of land management practices in the South Tobacco Creek Basin (STC) which forms part of the Red River Basin in southern Manitoba, Canada. The STC (~73 km2) is set in a gently rolling landscape of low relief (~200 m). Detailed field data such as crop type, tillage practices, crop residue and planting and harvesting dates are available from 1995 and are used to parameterize the model. While the majority of parameters are specified a priori, we have manually calibrated roughness and initial soil water storage parameters to compare the simulations with runoff observations at multiple scales (upstream catchment, mid-basin gauge and outlet gauge) and snow observations during 2000-2001 water year. The calibrated model based on the 2000-2001 period is further evaluated over the 2001-2011 period, which includes high inter-annual variability. The results suggest good agreement between observations and simulations and provide insight into hydrological controls. Snowmelt runoff is a major contributor to streamflow while the contribution of summer rainfall runoff is highly variable. The evaporative fraction is high during dry years (2002-2004) indicating a vertical flux controlled mass balance while the runoff fraction dominates during wet years (2005-2011), suggesting overland

    This study relates elemental content of a range of edible crops grown in soils severely polluted by metals and metalloids as affected by traditional smallholder management practices. Five agricultural plots close to a sulfidic waste dump were monitored. Soil analysis demonstrated elevated concentrations of As, Cu, Pb and Zn that were greatly in excess of maximum statutory limits for agricultural soils in the studied region. The main vegetables (lettuce, chard, onion, potatoes) and lemon, together with their associated soils, were measured for elemental content. Extractable soil element concentrations were very low. There were differences in elemental accumulation between crops, but none exceeded statutory concentrations in edible parts. Soil-plant transfer factors were uniformly low for all elements and crops. It is concluded that traditional soil management practices (annual liming and application of animal manures) have created conditions for sustainable long-term safety use, with potential for multiple end-use, of these highly polluted soils.

  20. Effect of Agricultural Practices on Hydrology and Water Chemistry in a Small Irrigated Catchment, Yakima River Basin, Washington

    The role of irrigation and artificial drainage in the hydrologic cycle and the transport of solutes in a small agricultural catchment in central Washington's Yakima Valley were explored using hydrologic, chemical, isotopic, age-dating, and mineralogical data from several environmental compartments, including stream water, ground water, overland flow, and streambed pore water. A conceptual understanding of catchment hydrology and solute transport was developed and an inverse end-member mixing analysis was used to further explore the effects of agriculture in this small catchment. The median concentrations of major solutes and nitrates were similar for the single field site and for the catchment outflow site, indicating that the net effects of transport processes for these constituents were similar at both scales. However, concentrations of nutrients were different at the two sites, suggesting that field-scale variations in agricultural practices as well as nearstream and instream biochemical processes are important components of agricultural chemical transformation and transport in this catchment. This work indicates that irrigation coupled with artificial drainage networks may exacerbate the ecological effects of agricultural runoff by increasing direct connectivity between fields and streams and minimizing potentially mitigating effects (denitrification and dilution, for example) of longer subsurface pathways.
