    2016-01-01

    Full Text Available Alongside other disciplines in social sciences, management researchers use mixed methods research more and more in conduct of their scientific investigations. Mixed methods approach can also be used in the field of production engineering. In comparison with traditional quantitative and qualitative research methods, reasons behind increasing popularity of mixed research method in management science can be traced in different factors. First of all, any particular discipline in management can be theoretically related to it. Second is that concurrent approach of mixed research method to inductive and deductive research logic provides researchers with opportunity to generate theory and test hypothesis in one study simultaneously. In addition, it provides a better justification for chosen method of investigation and higher validity for obtained answers to research questions. Despite increasing popularity of mixed research methods among management scholars, there is still need for a comprehensive approach to research design typology and process in mixed research method from the perspective of management science. The authors in this paper try to explain fundamental principles of mixed research method, its typology and different steps in its design process.

  7. Computational strategies to address chromatin structure problems

    2016-06-01

    While the genetic information is contained in double helical DNA, gene expression is a complex multilevel process that involves various functional units, from nucleosomes to fully formed chromatin fibers accompanied by a host of various chromatin binding enzymes. The chromatin fiber is a polymer composed of histone protein complexes upon which DNA wraps, like yarn upon many spools. The nature of chromatin structure has been an open question since the beginning of modern molecular biology. Many experiments have shown that the chromatin fiber is a highly dynamic entity with pronounced structural diversity that includes properties of idealized zig-zag and solenoid models, as well as other motifs. This diversity can produce a high packing ratio and thus inhibit access to a majority of the wound DNA. Despite much research, chromatin’s dynamic structure has not yet been fully described. Long stretches of chromatin fibers exhibit puzzling dynamic behavior that requires interpretation in the light of gene expression patterns in various tissue and organisms. The properties of chromatin fiber can be investigated with experimental techniques, like in vitro biochemistry, in vivo imagining, and high-throughput chromosome capture technology. Those techniques provide useful insights into the fiber’s structure and dynamics, but they are limited in resolution and scope, especially regarding compact fibers and chromosomes in the cellular milieu. Complementary but specialized modeling techniques are needed to handle large floppy polymers such as the chromatin fiber. In this review, we discuss current approaches in the chromatin structure field with an emphasis on modeling, such as molecular dynamics and coarse-grained computational approaches. Combinations of these computational techniques complement experiments and address many relevant biological problems, as we will illustrate with special focus on epigenetic modulation of chromatin structure.

    Full Text Available Computer conferencing is one of the more useful parts of computer-mediated communications (CMC, and is virtually ubiquitous in distance education. The temptation to analyze the resulting interaction has resulted in only partial success, however (Henri, 1992; Kanuka and Anderson, 1998; Rourke, Anderson, Garrison and Archer, 1999; Fahy, Crawford, Ally, Cookson, Keller and Prosser, 2000. Some suggest the problem is made more complex by failings of both technique and, more seriously, theory capable of guiding transcript analysis research (Gunawardena, Lowe and Anderson, 1997.We have previously described development and pilot-testing of an instrument and a process for transcript analysis, call the the TAT (Transcript Analysis Tool, based on a model originally developed by Zhu (1996. We found that the instrument and coding procedures used provided acceptable – sometimes excellent – levels of interrater reliability (varying from 70 percent to 94 percent in pilot applications, depending upon user training and practice with the instrument, and that results of pilots indicated the TAT discriminated well among the various types of statements found in online conferences (Fahy, et al., 2000.

    2015-01-01

    Given the lack of authentication mechanisms, the address resolution protocols ( ARPs) ( address resolution pro-tocol, neighbor discovery protocol, and so on) are vulnerable to attack, such as man in the middle and denial of service a-mong others. Therefore, the safety problem of the address resolution ( AR) has been significantly given focus, and, in this paper, two problems related to AR have been investigated. First, the indecisiveness of the AR is proven. Therefore, all de-cision methods adopted to ensure the AR are imperfect;second, the equivalence between the AR and the duplicate address detection ( DAD) process is proven. Thus, the AR and the DAD process can be replaced by each other, and can even be completed by the same process which will significantly simplify the design and implementation of the ARPs.%地址解析协议由于缺少认证机制而容易受到攻击,比如中间人攻击,DoS攻击等,因此其安全问题长久以来一直受到人们的关注。本文对地址解析有关的两个问题进行了研究。首先,证明了地址解析问题的不可判定性,这表明所有采用判定的方式来保障地址解析过程的方法都是不完美的;其次,证明了地址解析过程与重复地址检测过程的等价性。这个结论表明地址解析过程与重复地址检测过程可以互相替代,甚至由同一过程来完成,这将大大简化地址解析协议的设计与实现。

    Situated in the central region of South Africa, the Vaal Triangle is an area which plays a vital role in driving the economic dynamo of South Africa. Also, because of the concentration of heavy industry, it is an area which provides a challenge in effective air pollution control. The Vaal Triangle lies within the Vaal River Basin, at an altitude of 1 500 m above sea level. Meteorological conditions in the area are highly conducive to the formation of surface temperature inversions, resulting in a poor dispersion potential. Because of multiple sources of air pollution in the area, poor dispersion conditions increase the risk pollution build-up and subsequent adverse impacts. The situation is further exacerbated by the continued combustion of coal in households, even after the electrification of residences. This is particularly chronic in the developing communities and during winter. Vaal Triangle Air Pollution Health Study (VAPS) was initiated in 1990 by the Department of Health, the Medical Research Council and major industries in the area to determine effects of air pollution on the health of the community. The final results of that study summarised in this article, and options to ameliorate problems are addressed. (author)

  14. Improving ecosystem service frameworks to address wicked problems

    Directory of Open Access Journals (Sweden)

    Kathryn K. Davies

    2015-06-01

    Full Text Available Complex problems often result from the multiple interactions between human activities and ecosystems. The interconnected nature of ecological and social systems should be considered if these "wicked problems" are to be addressed. Ecosystem service approaches provide an opportunity to link ecosystem function with social values, but in practice the essential role that social dynamics play in the delivery of outcomes remains largely unexplored. Social factors such as management regimes, power relationships, skills, and values, can dramatically affect the definition and delivery of ecosystem services. Input from a diverse group of stakeholders improves the capacity of ecosystem service approaches to address wicked problems by acknowledging diverse sets of values and accounting for conflicting world views. Participatory modeling can incorporate both social and ecological dynamics into decision making that involves stakeholders, but is itself a complex social undertaking that may not yield precise or predictable outcomes. We explore the efficacy of different types of participatory modeling in relation to the integration of social values into ecosystem services frameworks and the generation of four important elements of social capital needed to address wicked problems: enhancing social learning and capacity building; increasing transparency; mediating power; and building trust. Our findings indicate that mediated modeling, group mapping, and mental/conceptual modeling are likely to generate elements of social capital that can improve ecosystem service frameworks. Participatory simulation, system dynamic modeling, and Bayesian belief networks, if utilized in isolation, were found to have a low likelihood of generating the social capital needed to improve ecosystem services frameworks. Scenario planning, companion modeling, group model building, and participatory mapping all generate a moderate to high level of social capital elements that improve the

    interface with the CNS. In 2013, two symposia were held independently to discuss this problem: one was held at the International Neuromodulation Society's 11th World Congress in Berlin and supported by the International Neuromodulation Society1 and the other at the 6th International Neural Engineering conference in San Diego2 and was supported by the NSF. Clearly, the neuromodulation and the neural engineering communities are keen to solve this problem. Experts from the field were assembled to discuss the problems and potential solutions. Although many important points were raised, few emerged as key issues. (1) The ability to access remotely and reliably internal neural signals . Although some of the technological problems have already been solved, this ability to access neural signals is still a significant problem since reliable and robust transcutaneous telemetry systems with large numbers of signals, each with wide bandwidth, are not readily available to researchers. (2) A translation strategy taking basic research to the clinic . The lack of understanding of the biological response to implanted constructs and the inability to monitor the sites and match the mechanical properties of the probe to the neural tissue properties continue to be an unsolved problem. In addition, the low levels of collaboration among neuroscientists, clinicians, patients and other stakeholders throughout different phases of research and development were considered to be significant impediments to progress. (3) Fundamental tools development procedures for neural interfacing . There are many laboratories testing various devices with different sets of criteria, but there is no consensus on the failure modes. The reliability, robustness of metrics and testing standards for such devices have not been established, either in academia or in industry. To start addressing this problem, the FDA has established a laboratory to test the reliability of some neural devices. Although the discussion was mostly

  16. Addressing the P2P Bootstrap Problem for Small Networks

    2010-01-01

    P2P overlays provide a framework for building distributed applications consisting of few to many resources with features including self-configuration, scalability, and resilience to node failures. Such systems have been successfully adopted in large-scale services for content delivery networks, file sharing, and data storage. In small-scale systems, they can be useful to address privacy concerns and for network applications that lack dedicated servers. The bootstrap problem, finding an existing peer in the overlay, remains a challenge to enabling these services for small-scale P2P systems. In large networks, the solution to the bootstrap problem has been the use of dedicated services, though creating and maintaining these systems requires expertise and resources, which constrain their usefulness and make them unappealing for small-scale systems. This paper surveys and summarizes requirements that allow peers potentially constrained by network connectivity to bootstrap small-scale overlays through the use of e...

    The key roles of academic research and teaching in addressing health in situations of conflict and instability are to better inform and better equip actors with the knowledge and skills to address health problems. The four key contributions of research are: quantifying the health problem, examining the contextual circumstances, investigating the epidemiology of health problems and evaluation of health care and humanitarian interventions. The role of teaching can complement research by distributing its' findings in addition to teaching skill sets to apply this knowledge and conduct further research. Academic research and teaching both play imperative roles in enabling more successful approaches in addressing health in situations of conflict and instability.

    2014-11-11

    The National Institute of Health invests US $30.9 billion annually in medical research. However, the subsequent impact of this research output on society and the economy is amplified dramatically as a result of the actual medical treatments, biomedical innovations, and various commercial enterprises that emanate from and depend on these findings. It is therefore a great concern to discover that much of published research is unreliable. We propose extending the open data concept to the culture of the scientific research community. By dialing down unproductive features of secrecy and competition, while ramping up cooperation and transparency, we make a case that what is published would then be less susceptible to the sometimes corrupting and confounding pressures to be first or journalistically attractive, which can compromise the more fundamental need to be robustly correct.

    This paper discussed the characteristics of addressing from the perspective of Internet address-ing mechanism. An Internet of things (IOT) resource ad-dressing iteration model was defined. In the model, a di-rect addressing mode for active nodes and an indirect addressing mode for passive codes were proposed, which meet the requirement for multiple encoding mode. A uni-fied IOT resource lightweight addressing scheme based on IPv6 has been proposed to implement the two addressing modes. The scheme utilized the virtual domain to solve the problem of the heterogeneous encoding. The paper imple-mented the addressing process from the Internet host to the sensor node based on IPv6 over low-power wireless personal area networks (6LoWPAN) protocol. The experi-ment results show that the scheme is performed to realize communication between wireless sensor networks and IPv6 networks.

    The strong CP problem is one of many puzzles in the theoretical description of elementary particles physics that still lacks an explanation. Solutions to that problem usually comprise new symmetries or fields or both. The main problem seems to be how to achieve small CP in the strong interactions despite large CP violation in weak interactions. Observation of CP violation is exclusively through the Higgs--Yukawa interactions. In this letter, we show that with minimal assumptions on the structure of mass (Yukawa) matrices the strong CP problem does not exist in the Standard Model and no extension to solve this is needed. However, to solve the flavor puzzle, models based on minimal SU(3) flavor groups leading to the proposed flavor matrices are favored.

    This work scales the present globalism of ecological and energetic problems. The ecological problem is connected with environment pollution by polymeric waste. The energetic problem - with traditional approaches of modern energetic, in particular, use of fossil fuel for energy production and concentration of capacities for ensuring overall performance of global power supply systems that doesn't guarantee a sustainable development of power for long prospect, doesn't provide power safety of the country. The second part of work is devoted to a choice of the most effective solutions of the present global problems. The authors have proposed the plasma-chemical method of the polymer waste processing and developed a schematic diagram of the reactor. The paper contains the results of the theoretical calculation of the polymer waste processing products. The reagents, allowing to obtain hydrogen and other liquid products from polymer waste are selected. It is proposed to use rare elements for increasing the efficiency of hydrogen production from polymer waste. The results of the calculation of the efficiency of hydrogen production from polymer waste using molybdenum are revealed in the paper.

    2017-03-08

    Problem complexity is often assumed to hamper effective environmental policy delivery. However, this claim is hardly substantiated, given the dominance of qualitative small-n designs in environmental governance research. We studied 37 types of contemporary problems defined by German water governance to assess the impact of problem complexity on policy delivery through public authorities. The analysis is based on a unique data set related to these problems, encompassing both in-depth interview-based data on complexities and independent official data on policy delivery. Our findings show that complexity in fact tends to delay implementation at the stage of planning. However, different dimensions of complexity (goals, variables, dynamics, interconnections, and uncertainty) impact on the different stages of policy delivery (goal formulation, stages and degrees of implementation) in various ways.

    Full Text Available The development of packed based multimedia networks reached a turning point when the ITU-T and the ETSIhave incorporated the IMS to the NGN. With the fast development of mobile communication more and more services andcontent are available. In contrast with fix network telephony both the services and the devices are personalized in the “mobileworld”. Services, known from the Internet - like e-mail, chat, browsing, presence, etc. – are already available via mobiledevices as well. The IMS originally wanted to exploit both the benefits of mobile networks and the fancy services of theInternet. But today it is already more than that. IMS is the core of the next generation telecommunication networks and abasis for fix-mobile convergent services. The fact however that IMS was originally a “mobile” standard, where IPv6 was notoddity generated some problems for the fix networks, where IPv4 is used. In this article I give an overview of these problemsand mention some solutions as well.

    The mission of the U.S. Nuclear Regulatory Commission (NRC) is to ensure the safe design, construction, and operation of commercial nuclear power plants and other facilities in the U.S.A. One of the main roles that the Office of Nuclear Regulatory Research (RES) plays in achieving the NRC mission is to plan, recommend, and implement research programs that address safety and technical issues deemed important by the NRC. The results of the research activities provide the bases for developing NRC positions or decisions on these issues. Also, RES performs confirmatory research for developing the basis to evaluate industry responses and positions on various regulatory requirements. This presentation summarizes some recent RES supported research activities that have addressed safety and technical issues related to valves and pumps. These activities include the efforts on determining valve and motor-operator responses under dynamic loads and pressure locking events, evaluation of monitoring equipment, and methods for detecting and trending aging of check valves and pumps. The role that RES is expected to play in future years to fulfill the NRC mission is also discussed.

    GRACEnet (Greenhouse gas Reduction through Agricultural Carbon Enhancement network) was conceived to build upon ongoing USDA Agricultural Research Service (ARS) research to improve soil productivity, while addressing the challenges and opportunities of interest in C sequestration from a climate change perspective. The vision for GRACEnet was and remains: Knowledge and information used to implement scientifically based agricultural management practices from the field to national policy scales on C sequestration, greenhouse gas (GHG) emissions, and environmental benefits. The national focus of GRACEnet uses a standardized approach by ARS laboratories and university and land manager (e.g. farmer and rancher) cooperators to assess C sequestration and GHG emission from different crop and grassland systems. Since 2002, GRACEnet has significantly expanded GHG mitigation science and delivered usable information to agricultural research and policy organizations. Recent developments suggest GRACEnet will have international impact by contributing leadership and technical guidance for the Global Research Alliance on Agricultural Greenhouse Gases.

    Our planet is dynamic; energy and matter constantly move between the hydrosphere, atmosphere and lithosphere on time scales from seconds to millenia. These tight interactions - including those between organisms and their physical environment - are what make Earth habitable. However, as Rachel Carson wrote, 'Only within the moment of time represented by the present century has one species - man - acquired significant power to alter the nature of this world'. Globalization and explosive population growth have generated far-reaching environmental problems on a scale that humanity has never faced before. Fortunately, our species has also developed an unprecedented ability to provide science-based solutions. Since processes impacting the environment involve complex biological, physical, chemical and geological interactions and feedbacks, they require the integration of expertise from all these scientific disciplines as well as input from policy makers, social scientists, and economists. This talk presents four examples of current interdisciplinary research projects conducted in my lab, each one related to a theme from one of Carson's books (Under the Sea-wind, The Sea Around Us, The Edge of the Sea, and Silent Spring). These projects, and others like them, provide hope that we can move toward a sustainable relationship with the natural world by encouraging the best scientists to conduct interdisciplinary research with direct applications for environmental management and stewardship.

    The NASA Capacity Building Program (Earth Science Division, Applied Sciences Program) works to enhance end-user capabilities to employ Earth observation and Earth science (EO/ES) data in decision-making. Open data access and user-tailored data delivery strategies are critical elements towards this end. User Experience (UX) and User Interface (UI) research methods can offer important contributions towards addressing data access challenges, particularly at the interface of science application/product development and product transition to end-users. This presentation focuses on developing nation contexts and describes methods, results, and lessons learned from two recent UX/UI efforts conducted in collaboration with NASA: the SERVIRglobal.net redesign project and the U.S. Water Partnership (USWP) Portal development effort. SERVIR, a collaborative venture among NASA, USAID, and global partners, seeks to improve environmental management and climate change response by helping governments and other stakeholders integrate EO and geospatial technologies into decision-making. The USWP, a collaboration among U.S. public and private sectors, harnesses U.S.-based resources and expertise to address water challenges in developing nations. SERVIR's study, conducted from 2010-2012, assessed and tested user needs, preferences, and online experiences to generate a more user-friendly online data portal at SERVIRglobal.net. The portal provides a central access interface to data and products from SERVIR's network of hubs in East Africa, the Hindu Kush Himalayas, and Mesoamerica. The second study, conducted by the USWP Secretariat and funded by the U.S. Department of State, seeks to match U.S.-based water information resources with developing nation stakeholder needs. The USWP study utilizes a multi-pronged approach to identify key design requirements and to understand the existing water data portal landscape. Adopting UX methods allows data distributors to design customized UIs that

    ASCO's Community Research Forum is a solution-oriented venue for community research sites to overcome barriers to conducting clinical trials. The key objectives of the Forum are to (1) convene community-based researchers to identify challenges to conducting research that ASCO can address, (2) develop solution-oriented projects to address these challenges to facilitate clinical trial participation in community research settings, and (3) shape ASCO programs and policies to support members engaged in community research. The Community Research Forum holds an annual in-person meeting that convenes physician investigators, research administrators, research nurses, and clinical research associates from community-based research programs and practices. To meet identified needs, the Community Research Forum has developed the ASCO Clinical Trial Workload Assessment Tool and the ASCO Research Program Quality Assessment Tool. Both of these tools will be available to the public in 2014. The Forum is currently exploring the concept and potential metrics of a research certification program to formally assess community-based research programs, and to identify gaps and areas to improve the program in order to meet quality standards. The Community Research Forum's website aims to serve as a go-to resource for community-based physician investigators and research staff. The Community Research Forum will continue to provide a forum for community-based researchers to network, share challenges, and develop initiatives that provide solutions and facilitate the conduct of clinical trials.

  20. Addressing the Cosmic Coincidence Problem in f(T) Gravity Models

    2014-01-01

    In this paper we address the well-known cosmic coincidence problem in the framework of the f(T) gravity. In order to achieve this, an interaction between dark energy and dark matter is considered. A constraint equation is obtained which generates the f(T) models that do not suffer from the coincidence problem. Due to the absence of a universally accepted interaction term introduced by a fundamental theory, the study is conducted over three different forms of chosen interaction terms. As an illustration two widely known models of f(T) gravity are taken into consideration and used in the setup designed to study the problem. The study reveals that there exists a perfect solution for the coincidence problem in the background of the second model while the first model remains utterly plagued by the phenomenon. This not only shows the cosmological viability but also the superiority of the second model over its counterpart.

    Full Text Available The standard of reading of learners in the intermediate phase is cause for considerable concern. In this article, the intermediate phase refers to grades 4, 5 and 6 (roughly ages 10 – 12. According to the 2008 Evaluation Assessment Tests for Reading, only 15% of learners in Grade 6 achieved the required literacy level. Clearly, reading achievement is a problem in South Africa. Although approximately 4% of any given population experience neurological reading problems, the focus of this article is on the significant number of learners in the intermediate phase who experience reading problems and the generic causes of reading problems for learners in general. The intent is to alert teachers and parents to the characteristics of a struggling reader so that the problem can be identified and addressed early. Firstly, ways in which learning problems are manifested are described. Secondly, a discussion of various types of reading problems, of which four, namely poor reading comprehension, inadequate reading fluency, a lack of vocabulary and a negative attitude towards reading, are discussed in depth. Strategies for struggling readers are presented and recommendations are made. The conclusion is that learners who experience reading problems can learn to read successfully when given the necessary support.

    Full Text Available The motivation to carry out this study stemmed from the generalized perception that nowadays youth lacks the skills for the 21st century. Especially the high-level competences like critical thinking, problem solving and autonomy. Several tools can help to improve these competences (e.g. the SCRATCH programming language, but, as researchers and educators, we are mostly concerned with the skill to recognize problems. What if we do not find problems to solve? What if we do not even feel the need to find or solve problems? The problem is to recognize the problem; the next step is to equate the problem; finally we have to feel the need to solve it. No need? No invention. Recognizing a problem is probably the biggest problem of everyday life, because we are permanently faced with problems (many ill-defined problems, which we need to identify, equate and solve.

    Understanding light scattering by nonspherical particles is crucial in modeling the transport of light in realistic structures such as biological tissues. We report the application of novel analytical approaches based on modified Wentzel-Kramers-Brillouin and equiphase-sphere methods that facilitate accurate characterization of light scattering by a wide range of irregularly shaped dielectric particles. We also demonstrate that these approaches have the potential to address the inverse-scattering problem by means of a spectral analysis of the total scattering cross section of arbitrarily shaped particles.

    Full Text Available ABSTRACT: It is clear that an urgent, major transformation needs to happen in the design of the built environment to respond to impending climate change and other environmental degradation. This paper will explain the potential role of architectural research centers in this transformation and provide examples from the Center for Sustainable Building Research (CSBR at the University of Minnesota. A research center can become a regional hub to coordinate and disseminate critical information. CSBR is leading the establishment of Architecture 2030 standards in Minnesota, assisting local governments in writing green building policy, providing design assistance to local government, developing tools to assist design decision making, providing technical assistance to the affordable housing community inMinnesota, and establishing a regional case study database that includes actual performance information. CSBR is creating a publicly accessible, credible knowledge base on new approaches, technologies and actual performance outcomes. Research centers such as CSBR can be a critical component of the necessary feedback loop often lacking in the building industry. A research center can also fill major gaps in providing in depth professional education as well as be a catalyst for demonstration projects and public education.

However, research use of Rorschach method besides of appropriate knowledge of assign procedures and interpretation rules, means a knowledge of specific methodological issues. The Rorschach indicators are nor independent, as they are a part of specific net, so in some research it is necessary to control basic variables not to get artifacts in our research. This is basically relied on researches where we compare groups, as well as in normative studies where through cross-cultural we compare Rorschach indicators. .

    2010-01-01

    During the past 3 decades numerous studies have documented the high prevalence of patient handling-related musculoskeletal injuries among healthcare workers and evaluated ergonomic interventions using mechanized equipment for lifting and moving patients. A great deal of research-based evidence now demonstrates the effectiveness of ergonomic interventions to reduce injury risk among healthcare workers who handle patients of average weights and sizes. In contrast, there is a lack of evidence-based research that evaluates ergonomic interventions for handling bariatric patients, whose extreme weights and sizes necessitate specialized handling equipment. The obesity epidemic, along with special medical and therapeutic concerns regarding bariatric patients, exacerbates healthcare workers' patient handling demands. The National Institute for Occupational Safety and Health is conducting a new study to evaluate bariatric patient handling hazards and interventions and identify evidence-based best practices for handling this population.

    President Barack Obama's State of the Union message, delivered on 24 January, touched on the need for basic research, energy production, support for clean energy, and environmental protection, but it included just one passing reference to climate change. In addition, the speech made no note of the Administration's recent denial of a controversial application for the Keystone XL pipeline to transport crude oil from Canada to the United States and made just an elliptical reference regarding the bankrupt Solyndra Corporation, which the administration had touted as a clean energy company. Innovation "demands basic research," Obama said, adding that Congress should not "gut these investments in our budget." Noting that one promise for innovation is American-made energy, Obama said he is directing the administration to "open more than 75% of our potential offshore oil and gas resources."

    Behavior problems among preschool children are common. They are important targets for intervention because early externalizing problems and self-regulation issues tend to persist without appropriate attention, and can affect later mental health and school achievement outcomes. However, few preschool curricula addressing social and emotional development exist, and evidence for effects are mixed. In this study, the Second Step Pre/Kindergarten Social and Emotional Learning curriculum was adapted and tested in a small cluster randomized pilot study of community preschool classrooms to determine if it could improve outcomes in: (1) individual children's teacher-rated behavior problems and prosocial skills; (2) classroom climate (classroom interactions and two measures of disruptive behavior); and (3) teacher interaction skills. Year 1 outcomes were modest and were accounted for by baseline differences. In Year 2, classroom climate, measured by independent observers, differed significantly in intervention classrooms, largely because of declines in control classrooms, and there was some evidence for better teacher interaction skills in intervention classrooms. The pattern of effects suggests important impacts on classroom quality worth investigating in a larger study. Both fidelity and implementation rates, as well as positive teacher responses to the curriculum, indicate potential for widespread adoption.

    When randomization is not possible, researchers must control for non-random assignment to experimental groups. One technique for statistical adjustment for non-random assignment is through the use of a two-stage analytical technique. The purpose of this study was to demonstrate the use of this technique to control for selection bias in examining the effects of the The Supplemental Program for Women, Infants, and Children's (WIC) on dental visits. From 5 data sources, an analysis file was constructed for 49,512 children ages 1-5 years. The two-stage technique was used to control for selection bias in WIC participation, the potentially endogenous variable. Specification tests showed that WIC participation was not random and that selection bias was present. The effects of the WIC on dental use differed by 36% after adjustment for selection bias by means of the two-stage technique. This technique can be used to control for potential selection bias in dental research when randomization is not possible.

Bangladesh is one of the most thickly populated and agriculture dependent developing countries of the world, and Bangladesh Agricultural University (BAU established in 1962 is only the premier seat of higher agricultural education and research in the country offering Masters and Doctoral degrees through the conventional face to face class room system. Since its establishment out of the total passed out bachelors (BSc Ag. so far till July 2007 only 31.29% Masters and 0.64% PhDs have been produced. Bangladesh has recently been connected to the information super-highway through submarine cables.

    Gilbert, David M

    2004-05-01

    Embryonic stem (ES) cells have almost unlimited regenerative capacity and can potentially generate any body tissue. Hence they hold great promise for the cure of degenerative human diseases. But their derivation and the potential for misuse have raised a number of ethical issues. These ethical issues threaten to paralyze pubic funding for ES cell research, leaving experimentation in the hands of the private sector and precluding the public's ability to monitor practices, research alternatives, and effectively address the very ethical issues that are cause for concern in the first place. With new technology being inevitable, and the potential for abuse high, government must stay involved if the public is to play a role in shaping the direction of research. In this essay, I will define levels of ethical conflict that can be delineated by the anticipated advances in technology. From the urgent need to derive new ES cell lines with existing technology, to the most far-reaching goal of deriving genetically identical tissues from an adult patients cells, technology-specific ethical dilemmas can be defined and addressed. This staged approach provides a solid ethical framework for moving forward with ES cell research. Moreover, by anticipating the moral conflicts to come, one can predict the types of scientific advances that could overcome these conflicts, and appropriately direct federal funding toward these goals to offset potentially less responsible research directives that will inevitably go forward via private or foreign funding.

    In traditional teaching, the fundamental concepts of electromagnetic induction are usually quickly analyzed, spending most of the time solving problems in a more or less rote manner. However, physics education research has shown that the fundamental concepts of the electromagnetic induction theory are barely understood by students. This article proposes an interactive teaching sequence introducing the topic of electromagnetic induction. The sequence has been designed based on contributions from physics education research. Particular attention is paid to the relationship between experimental findings (macroscopic level) and theoretical interpretation (microscopic level). An example of the activities that have been designed will also be presented, describing the implementation context and the corresponding findings. Since implementing the sequence, a considerable number of students have a more satisfactory grasp of the electromagnetic induction explicative model. However, difficulties are manifested in aspects that require a multilevel explanation, referring to deep structures where the system description is better defined.

One of the most valuable subjects in research methodology is to discuss about principles and skill of "Problem-oriented" researches that seems to be less known in literary studies.Propagation of problem-oriented researches in the field of Persian language and literature needs serious considerations to its principles and regulations, changing the viewpoint of literary researches, reconsideration in the curriculum of higher education centers, and finally revision in methods and procedure of doing a research plan in this field.Emphasing the necessity of the further consideration of problem-oriented in literary studies, in this article the characteristics and features of this type of research is discussed. Also the methods and skills of problem-finding in the field of literature are described and types of literary problem are introduced. Moreover the different steps that must be followed by a researcher in order to solve the literary problems are stated.

  2. Addressing complex healthcare problems in diverse settings: insights from activity theory.

    Science.gov (United States)

    Greig, Gail; Entwistle, Vikki A; Beech, Nic

    2012-02-01

    In the U.K., approaches to policy implementation, service improvement and quality assurance treat policy, management and clinical care as separate, hierarchical domains. They are often based on the central knowledge transfer (KT) theory idea that best practice solutions to complex problems can be identified and 'rolled out' across organisations. When the designated 'best practice' is not implemented, this is interpreted as local--particularly management--failure. Remedial actions include reiterating policy aims and tightening performance management of solution implementation, frequently to no avail. We propose activity theory (AT) as an alternative approach to identifying and understanding the challenges of addressing complex healthcare problems across diverse settings. AT challenges the KT conceptual separations between levels of policy, management and clinical care. It does not regard knowledge and practice as separable, and does not understand them in the commodified way that has typified some versions of KT theory. Instead, AT focuses on "objects of activity" which can be contested. It sees new practice as emerging from contradiction and understands knowledge and practice as fundamentally entwined, not separate. From an AT perspective, there can be no single best practice. The contributions of AT are that it enables us to understand the dynamics of knowledge-practice in activities rather than between levels. It shows how efforts to reduce variation from best practice may paradoxically remove a key source of practice improvement. After explaining the principles of AT we illustrate its explanatory potential through an ethnographic study of primary healthcare teams responding to a policy aim of reducing inappropriate hospital admissions of older people by the 'best practice' of rapid response teams.

    Full Text Available Abstract Background While the importance of promoting equity to achieve health is now recognised, the health gap continues to increase globally between and within countries. The description that follows looks at how the Cape Town Equity Gauge initiative, part of the Global Equity Gauge Alliance (GEGA is endeavouring to tackle this problem. We give an overview of the first phase of our research in which we did an initial assessment of health status and the socio-economic determinants of health across the subdistrict health structures of Cape Town. We then describe two projects from the second phase of our research in which we move from research to action. The first project, the Equity Tools for Managers Project, engages with health managers to develop two tools to address inequity: an Equity Measurement Tool which quantifies inequity in health service provision in financial terms, and a Equity Resource Allocation Tool which advocates for and guides action to rectify inequity in health service provision. The second project, the Water and Sanitation Project, engages with community structures and other sectors to address the problem of diarrhoea in one of the poorest areas in Cape Town through the establishment of a community forum and a pilot study into the acceptability of dry sanitation toilets. Methods A participatory approach was adopted. Both quantitative and qualitative methods were used. The first phase, the collection of measurements across the health subdistricts of Cape Town, used quantitative secondary data to demonstrate the inequities. In the Equity Tools for Managers Project further quantitative work was done, supplemented by qualitative policy analysis to study the constraints to implementing equity. The Water and Sanitation Project was primarily qualitative, using in-depth interviews and focus group discussions. These were used to gain an understanding of the impact of the inequities, in this instance, inadequate sanitation

    2010-01-01

    Forty years ago, when the National Institute on Alcohol Abuse and Alcoholism (NIAAA) was founded, alcoholism was considered an adult disease driven principally by physiological determinants. As NIAAA expanded its research portfolio, new data and insights were obtained that led to an increased focus on underage and young adult drinking. Fostered by interdisciplinary research, etiologic models were developed that recognized the multiplicity of relevant genetic and environmental influences. This shift in conceptualizing alcohol use disorders also was based on findings from large-scale, national studies indicating that late adolescence and early young adulthood were peak periods for the development of alcohol dependence and that early initiation of alcohol use (i.e., before age 15) was associated with a fourfold increase in the probability of subsequently developing alcohol dependence. In recent years, developmental studies and models of the initiation, escalation, and adverse consequences of underage and early young adult drinking have helped us to understand how alcohol use may influence, and be influenced by, developmental transitions or turning points. Major risk and protective factors are being identified and integrated into screening, prevention, and treatment programs to optimize interventions designed to reduce drinking problems among adolescents and young adults. In addition, regulatory policies, such as the minimum drinking age and zero-tolerance laws, are being implemented and evaluated for their impact on public health.

  8. A roadmap for climate change adaptation in Sweden's forests: addressing wicked problems using adaptive management

    Rist, L.; Felton, A.; Samuelsson, L.; Marald, E.; Karlsson, B.; Johansson, U.; Rosvall, O.

    2013-12-01

    Climate change is expected to have significant direct and indirect effects on forest ecosystems. Forests will have to adapt not only to changes in mean climate variables but also to increased climatic variability and altered disturbance regimes. Rates of change will likely exceed many forests capabilities to naturally adapt and many of today's trees will be exposed to the climates of 2090. In Sweden the effects are already being seen and more severe impacts are expected in the future. Exacerbating the challenge posed by climate change, a large proportion of Sweden's forests are, as a consequence of dominant production goals, greatly simplified and thus potentially more vulnerable to the uncertainties and risks associated with climate change. This simplification also confers reduced adaptive capacity to respond to potential impacts. Furthermore, many adaptation measures themselves carry uncertainties and risks. Future changes and effects are thus uncertain, yet forest managers, policymakers, scientists and other stakeholders must act. Strategies that build social and ecological resilience in the face of multiple interacting unknowns and surprises are needed. Adaptive management aims to collect and integrate knowledge about how a managed system is likely to respond to alternative management schemes and changing environmental conditions within a continuous decision process. There have been suggestions that adaptive management is not well suited to the large complex uncertainties associated with climate change and associated adaptation measures. However, more recently it has been suggested that adaptive management can handle such wicked problems, given adequate resources and a suitable breakdown of the targeted uncertainties. Here we test this hypothesis by evaluating how an adaptive management process could be used to manage the uncertainties and risks associated with securing resilient, biodiverse and productive forests in Sweden in the face of climate change.

    Each year, the developed world is flooded with complex new medical technologies, from robotic prosthetics to remote-controlled aspirin implants. Meanwhile, only about 10% of health research funds are spent addressing the pressing problems of developing nations, although these countries make up 93% of the worldwide burden of disease. In short, while a small fraction of the world pops brand-name pharmaceuticals, the majority suffers from poor sanitation, contaminated drinking water, preventable disease, and child mortality.

  15. DNA as patentable subject matter and a narrow framework for addressing the perceived problems caused by gene patents.

    Science.gov (United States)

    Schilling, Stephen H

    2011-12-01

    Concerns about the alleged harmful effects of gene patents--including hindered research and innovation and impeded patient access to high-quality genetic diagnostic tests--have resulted in overreactions from the public and throughout the legal profession. These overreactions are exemplified by Association for Molecular Pathology v. U.S. Patent and Trademark Office, a 2010 case in the Southern District of New York that held that isolated DNA is unpatentable subject matter under 35 U.S.C. § 101. The problem with these responses is that they fail to adequately consider the role that gene patents and patents on similar biomolecules play in facilitating investment in the costly and risky developmental processes required to transform the underlying inventions into marketable products. Accordingly, a more precisely refined solution is advisable. This Note proposes a narrowly tailored set of solutions to address the concerns about gene patents without destroying the incentives for companies to create and commercialize inventions derived from these and similar patents.

    2005-01-01

    This paper addresses the emergence of water security problems in North China with the aim of highlighting key water resources management and water security issues for the long-term development of North China. Three key problems related to water resources and security issues in North China in the 21st century are addressed, namely 1) the water cycle under environmental change, 2) agricultural water saving, and 3) water security. Development of international research related to these issues is also reviewed. The research plan developed recently by the Chinese Academy of Sciences (CAS) is discussed and suggestions on research and development of water resources science in North China are presented.Thanks to focus on experimental catchments and dedicated research stations, a detailed knowledge of the water cycle on North China farmland has been compiled. A range of techniques that include isotope tracers has been used to acquire hydrologic data. Much research has been devoted to developing distributed hydrological models at different scales. In the well irrigation district, five different water saving irrigation regimes have been investigated, and these regimes have had widespread application, and reduced water use 60-150 mm while they increased water use efficiency (WUE) by 20%-30%.Furthermore, preventing water pollution is the most essential step to ensure North China's water security.

    The field of nonlinear hyperbolic problems has been expanding very fast over the past few years, and has applications - actual and potential - in aerodynamics, multifluid flows, combustion, detonics amongst other. The difficulties that arise in application are of theoretical as well as numerical nature. In fact, the papers in this volume of proceedings deal to a greater extent with theoretical problems emerging in the resolution of nonlinear hyperbolic systems than with numerical methods. The volume provides an excellent up-to-date review of the current research trends in this area.

    2012-09-15

    Nanotechnology is widely associated with the promise of positively contributing to sustainability. However, this view often focuses on end-of-pipe applications, for instance, for water purification or energy efficiency, and relies on a narrow concept of sustainability. Approaching sustainability problems and solution options from a comprehensive and systemic perspective instead may yield quite different conclusions about the contribution of nanotechnology to sustainability. This study conceptualizes sustainability problems as complex constellations with several potential intervention points and amenable to different solution options. The study presents results from interdisciplinary workshops and literature reviews that appraise the contribution of the selected nanotechnologies to mitigate such problems. The study focuses exemplarily on the urban context to make the appraisals tangible and relevant. The solution potential of nanotechnology is explored not only for well-known urban sustainability problems such as water contamination and energy use but also for less obvious ones such as childhood obesity. Results indicate not only potentials but also limitations of nanotechnology's contribution to sustainability and can inform anticipatory governance of nanotechnology in general, and in the urban context in particular.

    The article presents a review of scientific problems and methods of ultraviolet astronomy, focusing on perspective scientific problems (directions) whose solution requires UV space observatories. These include reionization and the history of star formation in the Universe, searches for dark baryonic matter, physical and chemical processes in the interstellar medium and protoplanetary disks, the physics of accretion and outflows in astrophysical objects, from Active Galactic Nuclei to close binary stars, stellar activity (for both low-mass and high-mass stars), and processes occurring in the atmospheres of both planets in the solar system and exoplanets. Technological progress in UV astronomy achieved in recent years is also considered. The well advanced, international, Russian-led Spektr-UV (World Space Observatory—Ultraviolet) project is described in more detail. This project is directed at creating a major space observatory operational in the ultraviolet (115-310 nm). This observatory will provide an effective, and possibly the only, powerful means of observing in this spectral range over the next ten years, and will be an powerful tool for resolving many topical scientific problems.

    This project is aimed at bridging the three planes, from basic research, through enabling processes, toengineered systems. At the basic research plane, we have been working to improve our collective understanding aboutobstacles to implementing mitigation practices, owner decision processes (in connection with other MCEER projects), andpublic policy processes. At the level of enabling processes, we have been seeking to develop an understanding of howobstacles to greater mitigation can be overcome by improved policy design and processes. At the engineered systems plane,our work is intended to result in practical guidelines for devising policies and programs with appropriate motivation andincentives for implementing policies and programs once adopted. This phase of the research has been aimed, first, at athorough, multidisciplinary review of the literature concerning obstacles to implementation. Second, the research has focusedon advancing the state of the art by developing means for integrating the insights offered by diverse perspectives on theimplementation process from the several social, behavioral, and decision sciences. The research establishes a basis for testingour understanding of these processes in the case of hospital retrofit decisions.

    Farrington, D P

    1991-05-01

    The single-cohort, long-term longitudinal survey has many advantages in comparison with a cross-sectional survey in advancing knowledge about offending and other types of psychopathology, notably in providing information about onset and desistance, about continuity and prediction, and about within-individual change. However, the longitudinal survey also has significant problems, notably in confounding aging and period effects, delayed results, achieving continuity in funding and research direction, and cumulative attrition. This paper suggests the use of a multiple-cohort sequential strategy (the "accelerated longitudinal design") as a way of achieving the benefits of the longitudinal method while minimizing the problems in advancing knowledge about the natural history, causes, prevention, and treatment of psychopathological disorders.

  15. Rethinking gender-based violence during war: is violence against civilian men a problem worth addressing?

    Science.gov (United States)

    Linos, Natalia

    2009-04-01

    Gender-based violence during conflict and post-conflict situations has received increased attention in research and in the work of development agencies. Viewed primarily as a form of violence against women, this commentary questions whether male civilians have also been victims of gender-based violence during conflict, invisible due to stereotypes surrounding masculinity and a culturally permissive approach towards violence perpetrated against men, especially at times of war. The experience of civilian males of violence, including sexual violence, during the war in Bosnia and Herzegovina and other contemporary wars, suggests that the discourse on gender-based violence and public health research should begin exploring the specific needs of men. Drawing on Nancy Krieger's (Krieger, N. (2003). Genders, sexes, and health: what are the connections-and why does it matter? International Journal of Epidemiology, 32, 652-657) analysis on the differential role of 'sex' and 'gender' on a given exposure-outcome association, this commentary suggests that the impact of gender-based violence on health during conflict may be different for men and women and may require distinct therapeutic approaches. Given that perpetrators are often male, an extra level of stigma is added when heterosexual men are sexually violated, which may lead to underreporting and reduced health-service seeking behavior. Further public health research is needed to guide the work of humanitarian agencies working with survivors of gender-based violence in conflict and post-conflict settings to ensure equal access to appropriate health services for men and women.

    2016-01-01

    N-body dark matter simulations of structure formation in the $\\Lambda$CDM model predict a population of subhalos within Galactic halos that have higher central densities than inferred for satellites of the Milky Way, a tension known as the `too big to fail' problem. Proposed solutions include baryonic effects, a smaller mass for the Milky Way halo, and warm dark matter. We test these three possibilities using a semi-analytic model of galaxy formation to generate luminosity functions for Milky Way halo-analogue satellite populations, the results of which are then coupled to the Jiang & van den Bosch model of subhalo stripping to predict the subhalo $V_\\mathrm{max}$ functions for the 10 brightest satellites. We find that selecting the brightest satellites (as opposed to the most massive) and modelling the expulsion of gas by supernovae at early times increases the likelihood of generating the observed Milky Way satellite $V_\\mathrm{max}$ function. The preferred halo mass is $6\\times10^{11}M_{\\odot}$, which ...

  17. Activity theory as a tool to address the problem of chemistry's lack of relevance in secondary school chemical education

    Science.gov (United States)

    van Aalsvoort, Joke

    In a previous article, the problem of chemistry's lack of relevance in secondary chemical education was analysed using logical positivism as a tool. This article starts with the hypothesis that the problem can be addressed by means of activity theory, one of the important theories within the sociocultural school. The reason for this expectation is that, while logical positivism creates a divide between science and society, activity theory offers a model of society in which science and society are related. With the use of this model, a new course for grade nine has been constructed. This results in a confirmation of the hypothesis, at least at a theoretical level. A comparison with the Salters' approach is made in order to demonstrate the relative merits of a mediated way of dealing with the problem of the lack of relevance of chemistry in chemical education.

    Nimegeer, Amy; Farmer, Jane; West, Christina; Currie, Margaret

    2011-07-01

    Policy suggests that health service providers should plan services with communities. In remote and rural areas this is sometimes ineffective, resulting in resistance to change. An action research project investigated best practise in rural community engagement. As a result a planning 'game' was developed that uses a number of types and levels of cards and allows community members, as part of a process of engagement, to express their priorities and designs in a form that is directly usable by health service managers. The game is a unique community engagement resource in that it combines the priorities of the community (including their experiences of using services) with existing service data. It allows community members and service managers to apply their priorities for services to a healthcare budget to identify appropriate and affordable ways of providing safe local services.

  19. Lattice Boltzmann Methods to Address Fundamental Boiling and Two-Phase Problems

    Energy Technology Data Exchange (ETDEWEB)

    Uddin, Rizwan

    2012-01-01

    This report presents the progress made during the fourth (no cost extension) year of this three-year grant aimed at the development of a consistent Lattice Boltzmann formulation for boiling and two-phase flows. During the first year, a consistent LBM formulation for the simulation of a two-phase water-steam system was developed. Results of initial model validation in a range of thermo-dynamic conditions typical for Boiling Water Reactors (BWRs) were shown. Progress was made on several fronts during the second year. Most important of these included the simulation of the coalescence of two bubbles including the surface tension effects. Work during the third year focused on the development of a new lattice Boltzmann model, called the artificial interface lattice Boltzmann model (AILB model) for the 3 simulation of two-phase dynamics. The model is based on the principle of free energy minimization and invokes the Gibbs-Duhem equation in the formulation of non-ideal forcing function. This was reported in detail in the last progress report. Part of the efforts during the last (no-cost extension) year were focused on developing a parallel capability for the 2D as well as for the 3D codes developed in this project. This will be reported in the final report. Here we report the work carried out on testing the AILB model for conditions including the thermal effects. A simplified thermal LB model, based on the thermal energy distribution approach, was developed. The simplifications are made after neglecting the viscous heat dissipation and the work done by pressure in the original thermal energy distribution model. Details of the model are presented here, followed by a discussion of the boundary conditions, and then results for some two-phase thermal problems.

    Full Text Available This introspective essay was inspired by a desire to reflect on the use of qualitative research methods--where I am a Caucasian woman examining work experiences of women of color. I launched a journey backward to discover respondents' motivation for participating in my focus groups over the years, to closely examine their comfort level with a cross-ethnic dyad. The exercise enabled me to reflect on how I had negotiated power issues inherent in the research process. It contributes to the ongoing dialogue about autoethnography--where understanding of self in socio-cultural context is both the subject and object of the research enterprise. Overall, I interrogate epistemological and methodological practicalities of researching difference.

    Although community-based participatory research (CBPR) has been recognized as a useful approach for eliminating health disparities, less attention is given to how CBPR projects may address gender inequalities in health for immigrant older women. The goal of this article is to share culturally sensitive strategies and lessons learned from the PINE study-a population-based study of U.S. Chinese older adults that was strictly guided by the CBPR approach. Working with Chinese older women requires trust, respect, and understanding of their unique historical, social, and cultural positions. We also discuss implications for developing impact-driven research partnerships that meet the needs of this vulnerable population.

  2. Trends and problems in marital and family therapy research: Possible use of action research

    Directory of Open Access Journals (Sweden)

    Robert Cvetek

    2006-03-01

    Full Text Available Although research in marital and family therapy (MFT is becoming increasingly important, it continues to encounter several major problems. Studies have shown that research has very little influence on the practice of the majority of MFT practitioners. Practitioners see research as unrelated to their concerns. The practice of the majority of MFT practitioners is very individualized, as are the clinical problems and circumstances. Some have therefore started to emphasize the transferability of results instead of generalizability, and studying the practitioner's own practice instead of general concepts. Action research in the field of psychotherapy, as well as in the field of MFT, has been mainly overlooked as a potential method for solving these problems in MFT research. The paper addresses one of many possible ways to use the repeating cycles of the four basic steps in action research (observing and gathering information, reflecting, planning, and acting. The use of these four steps in action research enables therapists to study and improve their own practice in a more systematic, structured, and valid manner. This kind of research connects research and therapy. It is very individualized and oriented towards actions that create therapeutic changes.

  3. Beyond responsible conduct in research: new pedagogies to address macroethics of nanobiotechnologies.

    Science.gov (United States)

    Vallero, Daniel Alan

    2007-01-01

    A team of engineers, scientists, ethicists, and educational specialists are enhancing Duke University's Responsible Conduct of Research (RCR) program to ensure that graduate-level researchers in emerging fields are adequately prepared when confronted with macroethical issues associated with applications of new and emerging medical technologies. The focus is on nanoscale laboratory research conducted in the Center for Biologically Inspired Materials and Material Systems and the Center for Biological Tissue Engineering. Most present RCR programs address methodological ethics of the individual researcher or practitioner (i.e., microethical) issues, analogous to Kohlberg's theory of moral development. The resultant model from this project is the basis for departmental, center, and other more targeted ethical challenges stemming from research in emerging technologies, designed to provide comprehensive RCR training. The research successfully identified new ways of teaching students about macroethical issues (i.e., those that affect society). Three main dimensions of ethics in nanotechnology-related research are being stressed, namely, awareness, ethical decision making, and behavior. Workshops appear to enhance awareness of the ethical issues associated with emerging technologies. To date, attempts to affect decision making have been difficult, although in this study workshops were an effective means of identifying strategies to address ethical issues. A principal lesson learned has been the importance of providing a context for macroethical issues. For example, the workshop where an expert presented the technical aspects of environmental consequences of carbon nanotubes led to statistically significant differences between pre- and postworkshop understanding of societal risks. Conversely, in a workshop without the technical introduction, little difference was observed. This indicates that the stage of students' ethical understanding is an important determinant of

  4. Keynote address: Closing the research-to-practice gap in emergency medicine.

    Clancy, Carolyn M

    2007-11-01

    Emergency medicine in the United States is facing tremendous challenges due to recent public health emergencies, continuing threats of bioterrorism, and an increasing and unprecedented demand for emergency department services. These challenges include overcrowding; long waiting times; "boarding" of patients; ambulance diversion; a need for better, more reliable tools for triaging patients; and medical errors and other patient safety concerns. These challenges and concerns were brought to the forefront several years ago by the Institute of Medicine in several landmark reports that call for closing the research-to-practice gap in emergency medicine. The Agency for Healthcare Research and Quality is funding a number of projects that address many of the concerns raised in the reports, including the use of an advanced access appointment scheduling system to improve access to care; the use of an electronic medical record system to reduce waiting times and errors and improve patient and provider satisfaction; and the refinement of the Emergency Severity Index, a five-level triage scale to get patients to the right resources at the right time. The agency's Healthcare Cost and Utilization Project is gathering data that will allow researchers to examine a broad range of issues affecting the use, quality, and cost of emergency services. Although progress has been made over the past few years in closing the research-to-practice gap in emergency medicine, many challenges remain. The Agency for Healthcare Research and Quality has supported and will continue to support a broad portfolio of research to address the many challenges confronting emergency medicine, including ways to improve emergency care through the application of research findings.

    Full Text Available Based on Lakato’s notion of research programmes, the paper analyses the structure of the School Effectiveness Research (SER programme and reviews the main criticisms that have arisen, stressing those regarding its objectivity and theoretical limitations. Then, some proposals are made to address these criticisms, namely: to adopt a critical realist approach to the study of SE and an Abductive Theory of Scientific Method that lead to the development of sound theory in the field. Based on this analysis the paper concludes that, in terms of Lakatos, a movement towards a new research programme is needed in order to ensure that the main objectives originally set for SER can be eventually reached.

    Whole genome sequencing (WGS) can be a cost-effective and efficient means of diagnosis for some children, but it also raises a number of ethical concerns. One such concern is how researchers derive and communicate results from WGS, including future requests for further analysis of stored sequences. The purpose of this paper is to think about what is at stake, and for whom, in any solution that is developed to deal with such requests. To accomplish this task, this paper will utilize stakeholder theory, a common method used in business ethics. Several scenarios that connect stakeholder concerns and WGS will also posited and analyzed. This paper concludes by developing criteria composed of a series of questions that researchers can answer in order to more effectively address requests for further analysis of stored sequences.

    Data capture is an important process in the research lifecycle. Complete descriptive and representative information of the data or database is necessary during data collection whether in the field or in the research lab. The National Science Foundation's (NSF) Public Access Plan (2015) mandates the need for federally funded projects to make their research data more openly available. Developing, implementing, and integrating metadata workflows into to the research process of the data lifecycle facilitates improved data access while also addressing interoperability challenges for the geosciences such as data description and representation. Lack of metadata or data curation can contribute to (1) semantic, (2) ontology, and (3) data integration issues within and across disciplinary domains and projects. Some researchers of EarthCube funded projects have identified these issues as gaps. These gaps can contribute to interoperability data access, discovery, and integration issues between domain-specific and general data repositories. Academic Research Libraries have expertise in providing long-term discovery and access through the use of metadata standards and provision of access to research data, datasets, and publications via institutional repositories. Metadata crosswalks, open archival information systems (OAIS), trusted-repositories, data seal of approval, persistent URL, linking data, objects, resources, and publications in institutional repositories and digital content management systems are common components in the library discipline. These components contribute to a library perspective on data access and discovery that can benefit the geosciences. The USGS Community for Data Integration (CDI) has developed the Science Support Framework (SSF) for data management and integration within its community of practice for contribution to improved understanding of the Earth's physical and biological systems. The USGS CDI SSF can be used as a reference model to map to Earth

    The Space Weather Research Center (SWRC) has been providing space weather monitoring and forecasting services to NASA's robotic missions since its establishment in 2010. Embedded within the Community Coordinated Modeling Center (CCMC) (see Maddox et al. in Session IN026) and located at NASA Goddard Space Flight Center, SWRC has easy access to state-of-the-art modeling capabilities and proximity to space science and research expertise. By bridging space weather users and the research community, SWRC has been a catalyst for the efficient transition from research to operations and operations to research. In this presentation, we highlight a few unique aspects of SWRC's space weather services, such as addressing space weather throughout the solar system, pushing the frontier of space weather forecasting via the ensemble approach, providing direct personnel and tool support for spacecraft anomaly resolution, prompting development of multi-purpose tools and knowledge bases (see Wiegand et al. in the same session SM004), and educating and engaging the next generation of space weather scientists.

    Logistics constraints and operational challenges in the austere environs of the polar regions present unique technological and engineering problems. Working closely with universities, government agencies and industry, the U.S. Army Corps of Engineers Cold Regions Research and Engineering Lab (CRREL) routinely conducts scientific research and engineering in the Arctic, sub-Arctic and Antarctic covering a wide range of topics and applications. Current areas of focus include: improved mobility techniques for overland traverses; robotic vehicles for traversing, sampling and data collection; snow road and transportation characterization; integrated operational systems including airfield consolidation proof-of-concept studies; infrastructure technology such as firn air cooling, building design, snow foundations and sewage handling; remote/renewable autonomous power solutions for data collection; subsurface radar for crevasse detection and cryosphere characterization; ground-based lidar topographic scanning and near-real-time climate/environmental monitoring linked to AIS infrastructure. While these research and engineering efforts provide solutions and improved technology for specific problems, the impacts are many and wide-reaching and the results are often applicable to other challenging environments. Here, an overview of current research foci and projects is presented along with in-the-field applications, effects and future implications. The results and solutions of these efforts typically lead to technological improvements in operations and logistics which are cost-beneficial, thus freeing up funding dollars for fundamental scientific research. The links between basic research and applied solutions delivering far-reaching impacts (both large- and small-scale) on society, the environment, industry and scientific research are also demonstrated.

    In an increasingly fragmented gas market, the focus for national gas safety may not rest with one major utility or gas supplier but may be spread across many companies. There will also be many new organisations in a liberalized gas industry with varying views on the needs and benefits of safety related technology development but all agree there is a need to ensure that the good safety record of gas as a domestic fuel is maintained. The number of carbon monoxide (CO) incidents is not decreasing significantly despite an increased awareness of the problem. As a consequence, a two-year joint industry programme addressing issues related to carbon monoxide has been established, co-ordinated by BG Technology and supported by gas organisations, government agencies, manufacturers and suppliers across Europe and the World. The 2-year 2 pound million programme has been constructed as twelve separate projects addressing issues such as the reporting and analysis of domestic incidents, improved service or installation practice, CO alarm reliability and information dissemination. The paper gives results and achievements of the programme, through new techniques, standards, procedures or equipment and demonstrates how the gas industry can work together to meet common safety objectives.

    During the Anthropocene, mankind will face several global environmental challenges. One of the first and more successful responses provided by Science to these challenges is the collecting of long-term series of biophysical variables in order to improve our knowledge of natural systems. The huge amount of information gathered during the last decades by Research Infrastructures (RIs) has helped to understand the structure and functioning of natural systems at local and regional scales. But how can we address the global cross-scale and cross-disciplinary challenges posed by the global environment change? We believe that it will be necessary to observe, model better and understand the whole biosphere using long term data generated by international RIs. RIs play a key role on many of the last advances and discoveries in science, from the observation of the Higgs Boson at CERN to the exploration of the Universe by the telescopes of the European Southern Observatory in Chile. The scale of complexity, instrumentation, computing resources, technological advances, and also of the investments, and the size of research collaborations, do not have precedents in Science. RIs in environmental field are developing fast, but the corresponding communities need yet to further reflect the need for a wider global collaboration because the challenges to tackle are in essence of global nature. This contribution describes how COOP+ project (EU Horizon 2020 Coordination and Support Action) will promote the cooperation among RIs at a global scale to address global environmental challenges. Our project evolves from the experience of the sucessful FP7 COOPEUS project (see http://www.coopeus.eu), which explored the use and access to data from RIs in environmental research in Europe and USA. The general goal of COOP+ is to strengthen the links and coordination of the ESFRI RIs related to Marine Science (EMSO), Arctic and Atmospheric Research (EISCAT), Carbon Observation (ICOS) and Biodiversity

    Human activities are affecting the environment at continental and global scales. An example of this is the Mississippi basin where there has been a large scale loss of wetlands and water quality deterioration over the past century. Wetland and riparian ecosystems have been isolated from rivers and streams. Wetland loss is due both to drainage and reclamation, mainly for agriculture, and to isolation from the river by levees, as in the Mississippi delta. There has been a decline in water quality due to increasing use of fertilizers, enhanced drainage and the loss of wetlands for cleaning water. Water quality has deteriorated throughout the basin and high nitrogen in the Mississippi river is causing a large area of hypoxia in the Gulf of Mexico adjacent to the Mississippi delta. Since the causes of these problems are distributed over the basin, the solution also needs to be distributed over the basin. Ecotechnology and ecological engineering offer the only ecologically sound and cost-effective method of solving these problems. Wetlands to promote nitrogen removal, mainly through denitrification but also through burial and plant uptake, offer a sound ecotechnological solution. At the level of the Mississippi basin, changes in farming practices and use of wetlands for nitrogen assimilation can reduce nitrogen levels in the River. There are additional benefits of restoration of wetland and riverine ecosystems, flood control, reduction in public health threats, and enhanced wildlife and fisheries. At the local drainage basin level, the use of river diversions in the Mississippi delta can address both problems of coastal land loss and water quality deterioration. Nitrate levels in diverted river water are rapidly reduced as water flows through coastal watersheds. At the local level, wetlands are being used to treat municipal wastewater. This is a cost-effective method, which results in improved water quality, enhanced wetland productivity and increased accretion. The

    This study intend to understand how desertification research is organised in a south Mediterranean country, as is Spain. It is part of a larger work addressing soil and land research and its relationships with stakeholders. This wider work aims to explain the weakness of the United Nation Convention to Combat Desertification (UNCCD), which devoid of a scientific advisory panel. Within this framework, we assume that a fitting coordination between scientific knowledge and a better flow of information between researchers and policy makers is needed in order to slow down and reverse the impacts of land degradation on drylands. With this purpose we conducted an in-depth study at national level in Spain. The initial work focused on a small sample of published references in scientific journals indexed in the Web of Science. It allowed us to identify the most common thematic approaches and working issues, as well as the corresponding institutions and research teams and the relationships between them. The preliminary results of this study pointed out that two prevalent approaches at this national level could be identified. The first one is related to applied science being sensitive to socio-economic issues, and the second one is related to basic science studying the soil in depth, but it is often disconnected from socio-economic factors. We also noticed that the Spanish research teams acknowledge the other Spanish teams in this subject, as frequent co-citations are found in their papers, nevertheless, they do not collaborate. We also realised that the Web of Science database does not collect the wide spectrum of sociology, economics and the human implications of land degradation which use to be included in books or reports related to desertification. A new wider database was built compiling references of Web of Science related to "desertification", "land", "soil", "development" and "Spain" adding references from other socioeconomic databases. In a second stage we used

  14. What is the 'problem' that outreach work seeks to address and how might it be tackled? Seeking theory in a primary health prevention programme

    2011-12-01

    Full Text Available Abstract Background Preventive approaches to health are disproportionately accessed by the more affluent and recent health improvement policy advocates the use of targeted preventive primary care to reduce risk factors in poorer individuals and communities. Outreach has become part of the health service response. Outreach has a long history of engaging those who do not otherwise access services. It has, however, been described as eclectic in its purpose, clientele and mode of practice; its effectiveness is unproven. Using a primary prevention programme in the UK as a case, this paper addresses two research questions: what are the perceived problems of non-engagement that outreach aims to address; and, what specific mechanisms of outreach are hypothesised to tackle these. Methods Drawing on a wider programme evaluation, the study undertook qualitative interviews with strategically selected health-care professionals. The analysis was thematically guided by the concept of 'candidacy' which theorises the dynamic process through which services and individuals negotiate appropriate service use. Results The study identified seven types of engagement 'problem' and corresponding solutions. These 'problems' lie on a continuum of complexity in terms of the challenges they present to primary care. Reasons for non-engagement are congruent with the concept of 'candidacy' but point to ways in which it can be expanded. Conclusions The paper draws conclusions about the role of outreach in contributing to the implementation of inequalities focused primary prevention and identifies further research needed in the theoretical development of both outreach as an approach and candidacy as a conceptual framework.

    The Advanced Test Reactor National Scientific User Facility (ATR NSUF), based at the Idaho National Laboratory in the United States, is supporting Department of Energy and industry research efforts to ensure the properties of materials in light water reactors are well understood. The ATR NSUF is providing this support through three main efforts: establishing unique infrastructure necessary to conduct research on highly radioactive materials, conducting research in conjunction with industry partners on life extension relevant topics, and providing training courses to encourage more U.S. researchers to understand and address LWR materials issues. In 2010 and 2011, several advanced instruments with capability focused on resolving nuclear material performance issues through analysis on the micro (10-6 m) to atomic (10-10 m) scales were installed primarily at the Center for Advanced Energy Studies (CAES) in Idaho Falls, Idaho. These instruments included a local electrode atom probe (LEAP), a field-emission gun scanning transmission electron microscope (FEG-STEM), a focused ion beam (FIB) system, a Raman spectrometer, and an nanoindentor/atomic force microscope. Ongoing capability enhancements intended to support industry efforts include completion of two shielded, irradiation assisted stress corrosion cracking (IASCC) test loops, the first of which will come online in early calendar year 2013, a pressurized and controlled chemistry water loop for the ATR center flux trap, and a dedicated facility intended to house post irradiation examination equipment. In addition to capability enhancements at the main site in Idaho, the ATR NSUF also welcomed two new partner facilities in 2011 and two new partner facilities in 2012; the Oak Ridge National Laboratory, High Flux Isotope Reactor (HFIR) and associated hot cells and the University California Berkeley capabilities in irradiated materials analysis were added in 2011.

    Gow, Neil A. R.; Netea, Mihai G.

    2016-01-01

    Fungi cause more than a billion skin infections, more than 100 million mucosal infections, 10 million serious allergies and more than a million deaths each year. Global mortality owing to fungal infections is greater than for malaria and breast cancer and is equivalent to that owing to tuberculosis (TB) and HIV. These statistics evidence fungal infections as a major threat to human health and a major burden to healthcare budgets worldwide. Those patients who are at greatest risk of life-threatening fungal infections include those who have weakened immunity or have suffered trauma or other predisposing infections such as HIV. To address these global threats to human health, more research is urgently needed to understand the immunopathology of fungal disease and human disease susceptibility in order to augment the advances being made in fungal diagnostics and drug development. Here, we highlight some recent advances in basic research in medical mycology and fungal immunology that are beginning to inform clinical decisions and options for personalized medicine, vaccine development and adjunct immunotherapies. This article is part of the themed issue ‘Tackling emerging fungal threats to animal health, food security and ecosystem resilience’. PMID:28080988

  2. Addressing the antibiotic resistance problem with probiotics: Reducing the risk of its double-edged sword effect

    Directory of Open Access Journals (Sweden)

    Ivan Christian VJ Imperial

    2016-12-01

    Full Text Available Antibiotic resistance is a global public health problem that requires our attention. Indiscriminate antibiotic use is a major contributor in the introduction of selective pressures in our natural environments that have significantly contributed in the rapid emergence of antibiotic-resistant microbial strains. The use of probiotics in lieu of antibiotic therapy to address certain health conditions in both animals and humans may alleviate these antibiotic-mediated selective pressures. Probiotic use is defined as the actual application of live beneficial microbes to obtain a desired outcome by preventing diseased state or improving general health. Multiple studies have confirmed the beneficial effects of probiotic use in the health of both livestock and humans. As such, probiotics consumption is gaining popularity worldwide. However, concerns have been raised in the use of some probiotics strains that carry antibiotic resistance genes themselves, as they have the potential to pass the antibiotic resistance genes to pathogenic bacteria through horizontal gene transfer. Therefore, with the current public health concern on antibiotic resistance globally, in this review, we underscore the need to screen probiotic strains that are used in both livestock and human applications to assure their safety and mitigate their potential in significantly contributing to the spread of antibiotic resistance genes in our natural environments.

    Computational complexity is a particularly important objective. The idea of Landauer principle was extended through mapping three classic problems (sorting,ordered searching and max of N unordered numbers) into Maxwell demon thought experiment in this paper. The problems'complexity is defined on the entropy basis and the minimum energy required to solve them are rigorous deduced from the perspective of energy (entropy) and the second law of thermodynamics. Then the theoretical energy consumed by real program and basic operators of classical computer are both analyzed, the time complexity lower bounds of three problems'all possible algorithms are derived in this way. The lower bound is also deduced for the two n*n matrix multiplication problem. In the end, the reason why reversible computation is impossible and the possibility of super-linear energy consumption capacity which may be the power behind quantum computation are discussed, a conjecture is proposed which may prove NP!=P.

  6. Operational Research Techniques Used for Addressing Biodiversity Objectives into Forest Management: An Overview

    Directory of Open Access Journals (Sweden)

    Marta Ezquerro

    2016-10-01

    Full Text Available The integration of biodiversity into forest management has traditionally been a challenge for many researchers and practitioners. In this paper, we have provided a survey of forest management papers that use different Operations Research (OR methods in order to integrate biodiversity objectives into their planning models. One hundred and seventy-nine references appearing in the ISI Web of Science database in the last 30 years have been categorized and evaluated according to different attributes like model components, forest management elements, or biodiversity issues. The results show that many OR methods have been applied to deal with this challenging objective. Thus, up to 18 OR techniques, divided into four large groups, which have been employed in four or more articles, have been identified. However, it has been observed how the evolution of these papers in time apparently tended to increase only until 2008. Finally, two clear trends in this set of papers should be highlighted: the incorporation of spatial analysis tools into these operational research models and, second, the setting up of hybrid models, which combine different techniques to solve this type of problem.

    Kundrot, Craig E.; Edwards, J. Michelle

    2009-01-01

    The mission of NASA's Human Research Program (HRP) is to understand and reduce the risk to crew health and performance in exploration missions. The HRP addresses 27 specific risks by identifying and then filling gaps in understanding the risks and in the ability to disposition the risks. The primary bases for identifying gaps have been past experience and requirements definition. This approach has been very effective in identifying some important, relevant gaps, but may be inadequate for identifying gaps outside the past experience base. We are exploring the use of a gap taxonomy as a comprehensive, underlying conceptual framework that allows a more systematic identification of gaps. The taxonomy is based on these stages in medical care: prediction, prevention, detection/diagnosis, treatment, monitoring, rehabilitation, and lifetime surveillance. This gap taxonomy approach identifies new gaps in HRP health risks. Many of the new gaps suggest risk reduction approaches that are more cost effective than present approaches. A major benefit of the gap taxonomy approach is to identify new, economical approaches that reduce the likelihood and/or consequence of a risk.

  12. Addressing the challenges of cleft lip and palate research in India

    Directory of Open Access Journals (Sweden)

    Mossey Peter

    2009-10-01

    Full Text Available The Indian sub-continent remains one of the most populous areas of the world with an estimated population of 1.1 billion in India alone. This yields an estimated 24.5 million births per year and the birth prevalence of clefts is somewhere between 27,000 and 33,000 clefts per year. Inequalities exist, both in access to and quality of cleft care with distinct differences in urban versus rural access and over the years the accumulation of unrepaired clefts of the lip and palate make this a significant health care problem in India. In recent years the situation has been significantly improved through the intervention of Non Governmental Organisations such as SmileTrain and Transforming Faces Worldwide participating in primary surgical repair programmes. The cause of clefts is multi factorial with both genetic and environmental input and intensive research efforts have yielded significant advances in recent years facilitated by molecular technologies in the genetic field. India has tremendous potential to contribute by virtue of improving research expertise and a population that has genetic, cultural and socio-economic diversity. In 2008, the World Health Organisation (WHO has recognised that non-communicable diseases, including birth defects cause significant infant mortality and childhood morbidity and have included cleft lip and palate in their Global Burden of Disease (GBD initiative. This will fuel the interest of India in birth defects registration and international efforts aimed at improving quality of care and ultimately prevention of non-syndromic clefts of the lip and palate.

  13. Private property rights and selective private forest conservation: could a Nordic hybrid policy address a United States problem?

    Science.gov (United States)

    Mortimer, Michael J

    2008-05-01

    Political and legal conflicts between the need for targeted private forest conservation and the continued assurance of private property rights in the U.S. presents a seemingly intractable resource management problem. Scandinavian use of habitat protection areas on private forests offers an additional tool that may be suitable for solving the historical and on-going tension found within U.S. efforts to reconcile desires to maintain lands in a forested condition while also respecting private property rights. This article presents a comparative cross-sectional policy analysis of Sweden, Finland, and the U.S., supported with a supplemental case example from the Commonwealth of Virginia. Similarities in all three countries among forest ownership patterns, use of public subsidies, and changing attitudes towards conservation are generally encouraging. Additionally, Virginia's current consideration and development of state-wide forest policies focused on forestland and open space conservation suggests both a need and an opportunity to systematically assess the applicability of the Nordic forest reserve approach to local private forest conservation. Future research at a high-resolution, and specifically at the state level, should focus on the social and political factors that would ultimately determine the viability of a forest reserve program.

  14. Sexual problems in gay men: an overview of empirical research.

    Science.gov (United States)

    Sandfort, T G; de Keizer, M

    2001-01-01

    This article summarizes the findings and theoretical perspectives of 19 empirical studies of sexual problems in gay men. In order to understand these problems better, various differences between male homosexual and heterosexual functioning are discussed first. The studies included differ widely in terms of the issues explored, the populations studied, and the way data have been collected. In a few studies, researchers generally have looked at the prevalence and experience of sexual problems. In other studies, researchers have focused on the etiology and treatment of specific problems, such as sexual desire disorders, sexual aversion, excitement and arousal problems, orgasm disorders, sexual pain disorders and sexual compulsivity. Overall it is surprising how little is known about these problems in gay men. This is also true, however, for same-sex sexuality in general. Suggestions are made for studies that will enable us to obtain a better understanding of sexual problems in gay men.

  15. A Framework for Addressing Skeptics' Claims Using Evidence-Based Argumentation: Lessons Learned from Educational Research

    Lambert, J. L.; Bleicher, R. E.; Edwards, A.; Henderson, A.

    2012-12-01

    In science education, climate change is an issue that is especially useful for teaching concepts spanning several fields of science, as well the nature and practices of science. In response, we are developing a NASA-funded curriculum, titled Climate Science Investigations (CSI): South Florida, that teaches high school and first-year undergraduate level students how to analyze and use scientific data answer questions about climate change. To create an effective curriculum, we integrated lessons learned from our educational research conducted within our elementary science methods courses (Lambert, Lindgren, & Bleicher, 2012). For the past few years, we have been integrating climate science in our courses as a way to teach standards across several science disciplines and assessing our preservice teachers' gains in knowledge over the semesters. More recently, given the media attention and reports on the public's shift in opinion toward being more skeptical (Kellstedt, Zahran, & Vedlitz, 2008; Washington & Cook, 2011), we have assessed our students' perceptions about climate change and implemented strategies to help students use evidence-based scientific argumentation to address common claims of climate skeptics. In our elementary science methods courses, we framed climate change as a crosscutting theme, as well as a core idea, in the Next Generation Science Standards. We proposed that the issue and science of climate change would help preservice teachers not only become more interested in the topic, but also be more prepared to teach core science concepts spanning several disciplines (physical, life, and earth sciences). We also thought that highlighting the "practice of scientific inquiry" by teaching students to develop evidence-based arguments would help the preservice teachers become more analytical and able to differentiate scientific evidence from opinions, which could ultimately influence their perceptions on climate change. Lessons learned from our preservice

    2007-07-01

    Most health professionals today have heard of 'qualitative research' but many remain confused as to what it is and how to go about doing it. In this paper, two experienced qualitative researchers become engaged in conversation exploring the question 'what is qualitative research?' Lynne Giddings and Liz Smythe are Associate Professors in the Faculty of Health & Environmental Sciences at the Auckland University of Technology. They engage a reader in exploring issues such as: What might draw you to qualitative research? How does qualitative research make a difference to practice? How can reading a qualitative research article inform practice? From a qualitative perspective, what is 'truth'? How many participants? What happens to the data? What about the bias of the researcher? Can qualitative findings be trusted? Stories and exemplars are used to highlight the processes and issues involved in undertaking a qualitative research study.

    Iyer, Sharat P; Pancake, Laura S; Dandino, Elizabeth S; Wells, Kenneth B

    2015-12-01

    Barriers to sustainably implementing general medical interventions in community mental health (CMH) settings include role uncertainty, consumer engagement, workforce limitations, and sustainable reimbursement. To address these barriers, this project used a community-partnered participatory research framework to create a stakeholder-based general medical and wellness intervention in a large CMH organization, with consumers involved in all decision-making processes. Consumers faced practical barriers to participating in organizational decision making, but their narratives were critical in establishing priorities and ensuring sustainability. Addressing baseline knowledge and readiness of stakeholders and functional challenges to consumer involvement can aid stakeholder-based approaches to implementing general medical interventions in CMH settings.

  4. A proposed reductionist solution to address the methodological challenges of inconsistent reflexology maps and poor experimental controls in reflexology research: a discussion paper.

    Science.gov (United States)

    Jones, Jenny; Thomson, Patricia; Lauder, William; Leslie, Stephen J

    2013-03-01

    Reflexology is a complex massage intervention, based on the concept that specific areas of the feet (reflex points) correspond to individual internal organs within the body. Reflexologists trained in the popular Ingham reflexology method claim that massage to these points, using massage techniques unique to reflexology, stimulates an increase in blood supply to the corresponding organ. Reflexology researchers face two key methodological challenges that need to be addressed if a specific treatment-related hemodynamic effect is to be scientifically demonstrated. The first is the problem of inconsistent reflexology foot maps; the second is the issue of poor experimental controls. This article proposes a potential experimental solution that we believe can address both methodological challenges and in doing so, allow any specific hemodynamic treatment effect unique to reflexology to experimentally reveal itself.

  7. College Students' Views of Work-Life Balance in STEM Research Careers: Addressing Negative Preconceptions.

    Science.gov (United States)

    Tan-Wilson, Anna; Stamp, Nancy

    2015-01-01

    In career discussions, female undergraduates said that if they were to attend graduate school in science, technology, engineering, and mathematics (STEM) and were to follow a career based on their research training, they would have to give up having a family. A subsequent survey showed that many students, both men and women, thought work-life balance would be more difficult to achieve in a STEM research path than in other professions they were considering. Their views of STEM research being less family-friendly were more pronounced on issues of parental leaves and caring for children than finding a spouse/partner and landing two jobs in the same locality. To provide role models of work-life balance in STEM professions, we convened panels of dual-career couples who described how they worked together to raise their children while advancing their scientific careers. Our selection of panelists and topics of discussion were based on findings of social science research on work-life balance. On a survey with the same questions administered afterward, the changes in paired responses of male and female students with respect to all four issues showed a significant shift toward thinking that a research-based STEM career would be no more difficult than other careers they were considering.

    2014-03-01

    Emerging methodological research suggests that the World Wide Web ("Web") is an appropriate venue for survey data collection, and a promising area for delivering behavioral intervention. However, the use of the Web for research raises concerns regarding sample validity, particularly when the Web is used for recruitment and enrollment. The purpose of this paper is to describe the challenges experienced in two different Web-based studies in which participant misrepresentation threatened sample validity: a survey study and an online intervention study. The lessons learned from these experiences generated three types of strategies researchers can use to reduce the likelihood of participant misrepresentation for eligibility in Web-based research. Examples of procedural/design strategies, technical/software strategies and data analytic strategies are provided along with the methodological strengths and limitations of specific strategies. The discussion includes a series of considerations to guide researchers in the selection of strategies that may be most appropriate given the aims, resources and target population of their studies.

    2014-12-01

    The Midwest and Great Lakes region face a number of "Grand Challenges" associated with climate, land use, agriculture, and water resources infrastructure. These include sustainability of agricultural systems and related impacts to food security and the regional economy; sustainability of Great Lakes water levels; changing storm statistics and impacts to stormwater management and flooding; water quality in rivers and downstream receiving water bodies related to non-point source pollution on agricultural lands and combined sewer overflows in urban areas; urban impacts related to aging infrastructure and climate change, and ecosystem management and restoration. In the context of water management, groundwater resources are poorly understood in comparison with surface water resources, and regional-scale simulation models are needed to address questions of sustainability both in terms of supply and water quality. Interdisciplinary research at the University of Notre Dame is attempting to address these research challenges via 1) integrated macro-scale groundwater and surface water modeling to address issues related to sustainable water supply, ecosystem restoration, and agricultural impacts; 2) development of high-resolution regional climate models dynamically coupled to the Great Lakes to address urban impacts, changing storm statistics and to quantify precipitation and evaporation over the Great Lakes; 3) and integrated macro-scale hydrology and water quality modeling to assess the large-scale performance of innovative land management BMPs on agricultural land (such as the two-stage ditch, cover crops, and dynamic drainage control) intended to improve water quality.

    van der Veen, Wil E.; Belbruno, E. A.; Roelofsen Moody, T.

    2009-01-01

    One of the challenges in NASA ROSES E/PO is translating cutting edge research into products for which there is a demonstrated need. Rather than working from the premise that the "research is so cool’ that K-12 students or the public should learn about it, it is key to consult with the target audience to identify what their needs really are. The partnership between NJACE, Innovative Orbital Design, Inc., and Princeton offered a unique opportunity to translate intriguing but theoretical and mathematical research related to low energy orbits into a valuable education product. NJACE worked with educators to identify several needs with an intellectual link to this research: 1) Understanding of Gravity and Newton's Laws, 2) Understanding of Energy and Energy Transformations, 3) Integration of the sciences with math and technology, and 4) Knowledge of NASA's past accomplishments (such as the moon landings). Based on these identified needs, two science units were developed for students in grades 5-12 that integrate astronomy, physics, and the life sciences with math and technology. In addition an engaging public lecture was developed that tells a personal story of the quest for more economic space travel. In the past year, the workshops have been presented on three occasions, reaching over 75 teachers and demand exceeded available space with numerous teachers on waiting lists. The lecture has been presented numerous times at planetariums, museums, amateur astronomy and other clubs. We hope that our partnership will serve as a useful example of how to translate cutting edge research into valuable education products with an identified need. We will provide handouts with links to a website where the products and training can be downloaded in hope that others will help disseminate our product.

    Epidemiology, like all disciplines, exists within and is shaped by a culture that frames its ways of understanding. In the last 60 years epidemiology as a discipline and scientific approach has undergone major transition, but remains challenged by vestiges of the limiting frameworks of our origins which shape the way we approach questions, and even the questions we choose to investigate. A part of the current transformation is a reframing of our perspective and a broadening of our methods to encourage creativity and to encompass new types of evidence and new approaches to investigation and interpretation. Epidemiologists are developing innovative ways to approach increasingly complex problems and becoming more open to multi-disciplinary approaches to solving epidemiologic challenges.

    Full Text Available The resistance to antibiotics, appeared in the 50s, at the same time of the introduction of these drugs, has become today a public health emergency of international importance. This problem is extremely complex because it is based on many factors, including inappropriate use of antibiotics and their massive presence in the feed of farm animals. Today this problem has become a real public health priority not only for the clinical implications (increased morbidity, mortality and duration of disease, the possibility of developing complications and infections, but also for the economic impact of infections by bacteria resistant, due to the additional cost for more expensive drugs and procedures and for stretching the hospitalization. The European Centre for Disease Prevention and Control (ECDPC in Stockholm has recently estimated that the bacteria with multiple resistances are responsible for about half of thirty-seven thousand deaths per year in the twenty member countries of the European Union. The importance of this phenomenon has prompted several surveillance systems based on the collection of laboratory data to local or national level. To standardize and interpret the data collected and to facilitate comparison between different realities, in 1998 the EU has decided to finance a European surveillance network (EARSS: European Antimicrobial Resistance Surveillance System, which involves several national surveillance networks. Despite the increase of antimicrobial resistance in clinical isolates of both gram positive and gram negative, there are very few new antimicrobial agents in development. Only a multidisciplinary approach, combining various skills in medicine, can help us cope with this emergency and to use the resources available.

  20. Application of an engineering problem-solving methodology to address persistent problems in patient safety: a case study on retained surgical sponges after surgery.

    2013-09-01

    Despite innumerable attempts to eliminate the postoperative retention of surgical sponges, the medical error persists in operating rooms worldwide and places significant burden on patient safety, quality of care, financial resources, and hospital/physician reputation. The failure of countless solutions, from new sponge counting methods to radio labeled sponges, to truly eliminate the event in the operating room requires that the emerging field of health-care delivery science find innovative ways to approach the problem. Accordingly, the VA National Center for Patient Safety formed a unique collaboration with a team at the Thayer School of Engineering at Dartmouth College to evaluate the retention of surgical sponges after surgery and find a solution. The team used an engineering problem solving methodology to develop the best solution. To make the operating room a safe environment for patients, the team identified a need to make the sponge itself safe for use as opposed to resolving the relatively innocuous counting methods. In evaluation of this case study, the need for systematic engineering evaluation to resolve problems in health-care delivery becomes clear.

    Full Text Available Abstract Background To assist educators and researchers in improving the quality of medical research, we surveyed the editors and statistical reviewers of high-impact medical journals to ascertain the most frequent and critical statistical errors in submitted manuscripts. Findings The Editors-in-Chief and statistical reviewers of the 38 medical journals with the highest impact factor in the 2007 Science Journal Citation Report and the 2007 Social Science Journal Citation Report were invited to complete an online survey about the statistical and design problems they most frequently found in manuscripts. Content analysis of the responses identified major issues. Editors and statistical reviewers (n = 25 from 20 journals responded. Respondents described problems that we classified into two, broad themes: A. statistical and sampling issues and B. inadequate reporting clarity or completeness. Problems included in the first theme were (1 inappropriate or incomplete analysis, including violations of model assumptions and analysis errors, (2 uninformed use of propensity scores, (3 failing to account for clustering in data analysis, (4 improperly addressing missing data, and (5 power/sample size concerns. Issues subsumed under the second theme were (1 Inadequate description of the methods and analysis and (2 Misstatement of results, including undue emphasis on p-values and incorrect inferences and interpretations. Conclusions The scientific quality of submitted manuscripts would increase if researchers addressed these common design, analytical, and reporting issues. Improving the application and presentation of quantitative methods in scholarly manuscripts is essential to advancing medical research.

  2. Enabling Effective Problem-oriented Research for Sustainable Development

    Full Text Available Environmental problems caused by human activities are increasing; biodiversity is disappearing at an unprecedented rate, soils are being irreversibly damaged, freshwater is increasingly in short supply, and the climate is changing. To reverse or even to reduce these trends will require a radical transformation in the relationship between humans and the natural environment. Just how this can be achieved within, at most, a few decades is unknown, but it is clear that academia must play a crucial role. Many believe, however, that academic institutions need to become more effective in helping societies move toward sustainability. We first synthesize current thinking about this crisis of research effectiveness. We argue that those involved in producing knowledge to solve societal problems face three particular challenges: the complexity of real-world sustainability problems, maintaining impartiality when expert knowledge is used in decision making, and ensuring the salience of the scientific knowledge for decision makers. We discuss three strategies to meet these challenges: conducting research in interdisciplinary teams, forming research partnerships with actors and experts from outside academia, and framing research questions with the aim of solving specific problems (problem orientation. However, we argue that implementing these strategies within academia will require both cultural and institutional change. We then use concepts from transition management to suggest how academic institutions can make the necessary changes. At the level of system optimization, we call for: quality criteria, career incentives, and funding schemes that reward not only disciplinary excellence but also achievements in inter-/transdisciplinary work; professional services and training through specialized centers that facilitate problem-oriented research and reciprocal knowledge exchange with society; and the integration of sustainability and inter

    2011-08-01

    Full Text Available Abstract Background In order to improve the health of the most vulnerable groups in society, the WHO Commission on Social Determinants of Health (CSDH called for multi-sectoral action, which requires research and policy on the multiple and inter-linking factors shaping health outcomes. Most conceptual tools available to researchers tend to focus on singular and specific social determinants of health (SDH (e.g. social capital, empowerment, social inclusion. However, a new and innovative conceptual framework, known as social quality theory, facilitates a more complex and complete understanding of the SDH, with its focus on four domains: social cohesion, social inclusion, social empowerment and socioeconomic security, all within the same conceptual framework. This paper provides both an overview of social quality theory in addition to findings from a national survey of social quality in Australia, as a means of demonstrating the operationalisation of the theory. Methods Data were collected using a national random postal survey of 1044 respondents in September, 2009. Multivariate logistic regression analysis was conducted. Results Statistical analysis revealed that people on lower incomes (less than $45000 experience worse social quality across all of the four domains: lower socio-economic security, lower levels of membership of organisations (lower social cohesion, higher levels of discrimination and less political action (lower social inclusion and lower social empowerment. The findings were mixed in terms of age, with people over 65 years experiencing lower socio-economic security, but having higher levels of social cohesion, experiencing lower levels of discrimination (higher social inclusion and engaging in more political action (higher social empowerment. In terms of gender, women had higher social cohesion than men, although also experienced more discrimination (lower social inclusion. Conclusions Applying social quality theory allows

    Background: Government policy measures have a key role to play in the prevention and control of non-communicable diseases (NCDs). The Caribbean, a middle-income region, has the highest per capita burden of NCDs in the Americas. Our aim was to examine policy development and implementation between the years 2000 and 2013 on NCD prevention and control in Barbados, and to investigate factors promoting, and hindering, success. Methods: A qualitative case study design was used involving a structured policy document review and semi-structured interviews with key informants, identified through stakeholder analysis and ‘cascading.’ Documents were abstracted into a standard form. Interviews were recorded, transcribed verbatim and underwent framework analysis, guided by the multiple streams framework (MSF). There were 25 key informants, from the Ministry of Health (MoH), other government Ministries, civil society organisations, and the private sector. Results: A significant policy window opened between 2005 and 2007 in which new posts to address NCDs were created in the MoH, and a government supported multi-sectoral national NCD commission was established. Factors contributing to this government commitment and funding included a high level of awareness, throughout society, of the NCD burden, including media coverage of local research findings; the availability of policy recommendations by international bodies that could be adopted locally, notably the framework convention on tobacco control (FCTC); and the activities of local highly respected policy entrepreneurs with access to senior politicians, who were able to bring together political concern for the problem with potential policy solutions. However, factors were also identified that hindered multi-sectoral policy development in several areas, including around nutrition, physical activity, and alcohol. These included a lack of consensus (valence) on the nature of the problem, often framed as being predominantly one of

    2013-01-01

    We develop an Easy Java Simulation (EJS) model for students to visualize Newtons 1st and 3rd laws, using frictionless constant motion equation and a spring collision equation during impact. Using Physics by Inquiry instructional (PbI) strategy, the simulation and its problem based inquiry worksheet aim to enhance learning of these two Newtonian concepts. We report results from Experimental (N=62 students) and Control (N=67) Groups in 11 multiple choice questions pre and post tests, conducted by three teachers in the school. Results suggest, at 95 percent confidence level, significant improvement for concept of Newtons 1st Law while not so for Newtons 3rd Law. A Focus Group Discussion revealed students confirming the usefulness of the EJS model in visualizing the 1st Law while not so much for the 3rd Law. We speculate the design ideas for constant velocity motion in the computer model coupled with the PbI worksheet did allow for making sense and experiencing of the 1st Law, where traditional pen-paper represen...

    The wave of protests and populist uprisings in the Middle East has heightened the focus on a volatile region. But the emphasis on political issues has obscured underlying issues concerning education, infrastructure, research, innovation, entrepreneurship and sustainable environmental and social development. This volume, emerging in the aftermath of a conference and workshop on science and technology in the region, presents contributions from a range of experts from the Middle East, Europe, and the world to provide fresh new insights and perspectives on the challenges and prospects for regional development in the changing global context of our time. The authors explore such topics as: the role of information and communication technologies; mindset change in support of investment in intangible assets and risk-taking; how to approach cultural issues, institutions and governance; collaborations with other regions, and; benchmarking performance while drawing lessons of relevance for the special local context.

    2016-06-01

    Men, transgender people, and those working in off-street locales have historically been underrepresented in sex work health research. Failure to include all sections of sex worker populations precludes comprehensive understandings about a range of population health issues, including potential variations in the manifestation of such issues within and between population subgroups, which in turn can impede the development of effective services and interventions. In this article, we describe our attempts to define, determine, and recruit a purposeful sample for a qualitative study examining the interrelationships between sex workers' health and the working conditions in the Vancouver off-street sex industry. Detailed is our application of ethnographic mapping approaches to generate information about population diversity and work settings within distinct geographical boundaries. Bearing in mind the challenges and the overwhelming discrimination sex workers experience, we scope recommendations for safe and effective purposeful sampling inclusive of sex workers' heterogeneity.

  10. Spatial extent in demographic research - approach and problems

    Directory of Open Access Journals (Sweden)

    Knežević Aleksandar

    2015-01-01

    Full Text Available One of the starting methodological problems in demographic research is the definition of spatial extent, which mostly doesn’t correspond to spatial extent already defined by different levels of administrative-territorial unitsthat are used for distribution of usable statistical data. That’s why determining the spatial extent of a demographic research is closely tied with administrative-territorial division of the territory that is being researched, wherein the fact that differentiation of demographic phenomena and processes cannot be the only basis of setting the principles of regionalization must be strictly acknowledged. This problem is particularly common in historical demographic analyses of geographically determined wholes, which are in administratively-territorial sense represented by one or more smaller territorial units, with their borders changing through the history, which directly affects comparability of the statistical data, and makes it considerably more difficult to track demographic change through longer time intervals. The result of these efforts is usually a solution based on a compromise which enables us to examine the dynamics of population change with little deviation from already defined borders of regional geographic wholes. For that reason in this paper the problem of defining spatial extent in demographic research is examined trough several different approaches in case of Eastern Serbia, as a geographically determined region, a historic area, a spatially functioning whole and as a statistical unit for demographic research, with no judgment calls in regard to any of the regionalization principles.

    Approximately 200 years have passed since Malthus pointed out various population problems. Since then, many scholars have discussed and researched the population principles attributable to Malthus. Formal demography has developed recently. However, the conception of population problems has been discussed more on an a priori level rather than on a philosophical level. We cannot conceive of man himself without introspection about what is man. This problem has also been approached by other philosophers--Plato, Aristotle, Kant, Feuerbach, Marx, Neitzche, Scheler, Heidegger, Dilthey, Pascal, Northrop, Sartre, Buber, Landmann, and others. It is possible to classify views of the human being into about 20 patterns. Until now, there have been different ideas among population researchers and students in Japan. Some have thought of population as the abstract mass of man; others thought of it as a concrete mass of man. Further inquiry into this idea would allow the author to proceed to examine man himself, population, and population problems from a philosopher's point of view. A new theory of population problems could then be established by improving the population principles of Malthus. (author's modified)

  12. A problem with inclusion in learning disability research.

    McClimens, Alex; Allmark, Peter

    2011-09-01

    People with severe learning disability are particularly difficult to include in the research process. As a result, researchers may be tempted to focus on those with learning disability who can be included. The problem is exacerbated in this field as the political agenda of inclusion and involvement is driven by those people with learning disability who are the higher functioning. To overcome this we should first detach the notion of consent from ideas about autonomy and think instead of it as a way to avoid wronging others; this fits the original historical use of consent in research. This allows us to think in terms of including participants to the best of their abilities rather than in terms of a threshold of autonomy. Researchers could then use imaginative ways to include the least able and to ensure they are not wronged in research or by exclusion from it.

    The issues of industrial productivity and economic competitiveness are of major significance in the U.S. at present. By advancing the science of design, and by creating a broad computer-based methodology for automating the design of artifacts and of industrial processes, we can attain dramatic improvements in productivity. It is our thesis that developments in computer science, especially in Artificial Intelligence (AI) and in related areas of advanced computing, provide us with a unique opportunity to push beyond the present level of computer aided automation technology and to attain substantial advances in the understanding and mechanization of design processes. To attain these goals, we need to build on top of the present state of AI, and to accelerate research and development in areas that are especially relevant to design problems of realistic complexity. We propose an approach to the special challenges in this area, which combines 'core work' in AI with the development of systems for handling significant design tasks. We discuss the general nature of design problems, the scientific issues involved in studying them with the help of AI approaches, and the methodological/technical issues that one must face in developing AI systems for handling advanced design tasks. Looking at basic work in AI from the perspective of design automation, we identify a number of research problems that need special attention. These include finding solution methods for handling multiple interacting goals, formation problems, problem decompositions, and redesign problems; choosing representations for design problems with emphasis on the concept of a design record; and developing approaches for the acquisition and structuring of domain knowledge with emphasis on finding useful approximations to domain theories. Progress in handling these research problems will have major impact both on our understanding of design processes and their automation, and also on several fundamental questions

    Secretary of Energy Steven Chu gave the keynote address at the 2011 EFRC Summit and Forum. In his talk, Secretary Chu highlighted the need to "unleash America's science and research community" to achieve energy breakthroughs. The 2011 EFRC Summit and Forum brought together the EFRC community and science and policy leaders from universities, national laboratories, industry and government to discuss "Science for our Nation's Energy Future." In August 2009, the Office of Science established 46 Energy Frontier Research Centers. The EFRCs are collaborative research efforts intended to accelerate high-risk, high-reward fundamental research, the scientific basis for transformative energy technologies of the future. These Centers involve universities, national laboratories, nonprofit organizations, and for-profit firms, singly or in partnerships, selected by scientific peer review. They are funded at $2 to $5 million per year for a total planned DOE commitment of $777 million over the initial five-year award period, pending Congressional appropriations. These integrated, multi-investigator Centers are conducting fundamental research focusing on one or more of several “grand challenges” and use-inspired “basic research needs” recently identified in major strategic planning efforts by the scientific community. The purpose of the EFRCs is to integrate the talents and expertise of leading scientists in a setting designed to accelerate research that transforms the future of energy and the environment.

    Two instances of research facilities responding to public scrutiny will be discussed. The first concerns emissions from a "tritium labeling facility" operated at Lawrence Berkeley National Laboratory (LBNL); the second deals with releases of plutonium from Lawrence Livermore National Laboratory (LLNL). There are many parallels between these two cases, both of which are still ongoing. In both, the national laboratory is the acknowledged source of low-level (by regulatory standards) radioactive contamination in the community. A major purpose of both investigations is to determine the degree of the contamination and the threat it poses to public health and the environment. The examining panel or committee is similarly constituted in the two cases, including representatives from all four categories of stakeholders: decision makers; scientists and other professionals doing the analysis/assessment; environmental activist or public interest groups; and "ordinary" citizens (nearly everyone else not in one or more of the first three camps). Both involved community participation from the beginning. The levels of outrage over the events triggering the assessment are comparable; though "discovered" or "appreciated" only a few years ago, the release of radiation in both cases occurred or began occurring more than a decade ago. The meetings have been conducted in a similar manner, with comparable frequency, often utilizing the services of professional facilitators. In both cases, the sharply contrasting perceptions of risk commonly seen between scientists and activists were present from the beginning, though the contrast was sharper and more problematical in the Berkeley case. Yet, the Livermore case seems to be progressing towards a satisfactory resolution, while the Berkeley case remains mired in ill-will, with few tangible results after two years of effort. We perceive a wide gap in negotiation skills (at the very least), and a considerable difference in willingness to

    Full Text Available A recent and comprehensive review of the use of race and ethnicity in research that address health disparities in epidemiology and public health is provided. First it is described the theoretical basis upon which race and ethnicity differ drawing from previous work in anthropology, social science and public health. Second, it is presented a review of 280 articles published in high impacts factor journals in regards to public health and epidemiology from 2009-2011. An analytical grid enabled the examination of conceptual, theoretical and methodological questions related to the use of both concepts. The majority of articles reviewed were grounded in a theoretical framework and provided interpretations from various models. However, key problems identified include a a failure from researchers to differentiate between the concepts of race and ethnicity; b an inappropriate use of racial categories to ascribe ethnicity; c a lack of transparency in the methods used to assess both concepts; and d failure to address limits associated with the construction of racial or ethnic taxonomies and their use. In conclusion, future studies examining health disparities should clearly establish the distinction between race and ethnicity, develop theoretically driven research and address specific questions about the relationships between race, ethnicity and health. One argue that one way to think about ethnicity, race and health is to dichotomize research into two sets of questions about the relationship between human diversity and health.

    Appuhamilage Dilshani Eranga Sarathchandra, Walakada

    Scientific discoveries take place within scientific communities that are established in legitimating organizations such as universities and research institutes. Often times, scientists undergo tensions and paradoxes as they evaluate the risks they are willing to accept in their work. The types of risk/benefit decisions scientists make to determine which research projects to engage in and how they engage in them is more important than ever, due to current restrictions on funding for scientific research. The main objective of this dissertation is to analyze the ways in which university bioscientists define, evaluate, and manage risks in science, i.e. their risk epistemologies. In the process, I examine bioscientists' risk perceptions and demographic and contextual factors that influence those perceptions. Additionally, I investigate the associations between risk perceptions and research problem choices. This dissertation followed a mix-methods approach. The data collection included twenty semi-structured in-depth interviews and a large-scale online survey of university bioscientists. Based on three theoretically driven research questions that surfaced through examining current literature, I organized the dissertation into three different essays. The first essay explores risk epistemologies of university bioscientists as they determine the best trajectories for their scientific careers. This essay analyses data gathered by conducting in-depth interviews meant to elicit university bioscientists' different understandings of the notion of risk. The second essay quantifies bioscientists' risk perceptions using data gathered from the online survey. In this essay, I investigate the influence of life-course, gender, sources of funding, research orientation, network interactions, and perceived significance of research on risk perception. In the third essay I use data gathered from the online survey to investigate the associations between university bioscientists' risk

    Full Text Available Abstract. The authors continue to explore the issue of practical methodology of research studies (Education and Science No 8, 2014. The aim of the study is to reveal theoretical and practical issues of empirical-research activity at the stages of conceptual problem understanding of pedagogical research, ideas promotion, development of the conception of their practical implementation and formation of scientifically grounded constructive hypotheses. Methods. The applied methods include theoretical analysis, synthesis, abstraction, idealization, generalization, specification, comparison, classification, extrapolation, modelling and hermeneutic interpretation. Results. Scientifically grounded description of the process of creative research of educational problems is presented in the paper. The content of such notions as «concept», «creative core», «idea», «plot», and «research hypothesis» is revealed. The creative core of scientific research is considered in close relation to the key aspects of the scientific inquiry: problematics definition, research topic and subject selection, clarification of initial facts and theoretical statements, definition of the conceptual framework, determination of essential novelty. The authors explore the mechanisms of the scientific research through the analysis of the educational situation and initial facts to the formation of a conceptual framework of research and the further working out of its instrumental component. The creative core of research is characterised as its most difficult element including the inception of idea transformation, its realisation into some conception and expansion into productive hypothesis. The authors describe the types of hypotheses, such as working and scientific (ready, functional and explanatory. The logical and gnoseological structure of a scientific hypothesis is shown in the study. The methodological requirements to the formulation of the scientific hypotheses are

Introduction At the outset, I should like to acknowledge that part of the title above, which tries to capture the main flavour of this meeting, and has been borrowed from one of the plenary talks at the conference. When we set out to make the programme for the conference, we thought of beginning with observations on the Universe, but then we certainly wanted to go further and address deeper questions, which were at the very foundations of our inquiry, and understanding on the nature and structure of the Universe. I believe, we succeeded to a good extent, and it is all here for you in the form of these Conference Proceedings, which have been aptly titled as 'Vishwa Mimansa', which could be possibly translated as 'Analysis of the Universe'! It is my great pleasure and privilege to welcome you all to the ICGC-2011 meeting at Goa. The International Conference on Gravitation and Cosmology (ICGC) series of meetings are being organized by the Indian Association for General Relativity and Gravitation (IAGRG), and the first such meeting was planned and conducted in Goa in 1987, with subsequent meetings taking place at a duration of about four years at various locations in India. So, it was thought appropriate to return to Goa to celebrate the 25 years of the ICGC meetings. The recollections from that first meeting have been recorded elsewhere here in these Proceedings. The research and teaching on gravitation and cosmology was initiated quite early in India, by V V Narlikar at the Banares Hindu University, and by N R Sen in Kolkata in the 1930s. In course of time, this activity grew and gained momentum, and in early 1969, at the felicitation held for the 60 years of V V Narlikar at a conference in Ahmedabad, P C Vaidya proposed the formation of the IAGRG society, with V V Narlikar being the first President.

  2. Theory Building in Qualitative Research: Reconsidering the Problem of Induction

    Directory of Open Access Journals (Sweden)

    Pedro F. Bendassolli

    2013-01-01

    Full Text Available The problem of induction refers to the difficulties involved in the process of justifying experience-based scientific conclusions. More specifically, inductive reasoning assumes a leap from singular observational statements to general theoretical statements. It calls into question the role of empirical evidence in the theory-building process. In the philosophy of science, the validity of inductive reasoning has been severely questioned since at least the writings of David HUME. At the same time, induction has been lauded as one of the main pillars of qualitative research methods, and its identity as such has consolidated to the detriment of hypothetical-deductive methods. This article proposes reviving discussion on the problem of induction in qualitative research. It is argued that qualitative methods inherit many of the tensions intrinsic to inductive reasoning, such as those between the demands of empiricism and of formal scientific explanation, suggesting the need to reconsider the role of theory in qualitative research.

    Collaborative and participatory research approaches have received considerable attention as means to understanding and addressing disparities in health and health care. In this article, the authors describe the process of building a three-way partnership among two academic health centers-Duke University and the University of North Carolina-and members of the Latino community in North Carolina to develop and pilot test a lay health advisor program to improve Latina immigrants' mental health and coping skills. The authors applied the principles of participatory research to engage community and academic partners, to select the health topic and population, and to develop program goals and objectives. Key challenges were negotiating administrative structures and learning institutional cultures, as well as dealing with contextual issues such as mental health reform and antiimmigrant sentiment in the state.Some important lessons learned are to seek opportunities for taking advantage of existing relationships and expertise at each academic institution, to be respectful of the burden of research on vulnerable communities, and to involve community partners at all stages of the process.

    Full Text Available Language has different functions. One of them, the communication, is fundamental for the investigation, because the textualization of its process and results is the base of the diffusion of the advance and increase of the scientific knowledge. However, most students - and those who are not already so - present difficulties in using references, in breaks in cohesion, or in logical and argumentative coherence. Such difficulties limit the generation of texts, as they constitute an obstacle to translate written ideas into an argumentative discourse, typical of science and research. The latter requires the argued presentation of an idea, whose perception, description and obvious reasons make up the problem that is wanted to know, to explain, to verify, to understand or to interpret. Therefore, this short space / time has the purpose of reflecting on the discursive construction of the problem of an inquiry. Its importance lies precisely in the disadvantages of its configuration. In this sense, the reflection is developed from a vision of language and communication; The argumentative discourse and the types of reasoning involved in order to fulfill certain guidelines that underlie the construction of the problem of inquiry and its approach in terms of a positivist-quantitative and / or qualitative study.

    Osteoarthritis (OA) accounts for more disability among the elderly than any other disease and is associated with an increased mortality rate. The prevalence in Europe will rise in the future since this continent has a strongly ageing population and an obesity epidemic; obesity and age both being major risk factors for OA. No adequate therapeutic options, besides joint replacement, are available, although they are greatly needed and should be acquired by adequate research investments. However, the perspective on OA from a researcher's point of view is not always aligned with the perspective of a patient with OA. Researchers base their views on OA mainly on abnormalities in structure and function while patients consider OA as a collection of symptoms. In this viewpoint paper, we discuss the possibility of translating the most important clinical problems into pathophysiological research goals to facilitate the translation from bench to bedside and vice versa. This viewpoint is the outcome of a dialogue within the 'European League Against Rheumatism study group on OA' and People with Arthritis/Rheumatism across Europe (PARE) representatives.

    BACKGROUND: The paper addressed a unique challenge for public health and community research in rural China, i.e., the very large percentage of young adults that comprises a highly mobile working population that has been an essential component of the country's economic transformation. Fluid local demographic patterns potentially have a substantial impact on sample representativeness and data validity. METHODS: This report is based upon a cross sectional survey with face-to-face interviews of residents aged 16-34 years in rural communities of Mianyang, Sichuan Province, China. Two waves of fieldwork and other strategies were adopted in response to recruitment challenges. RESULTS: 1654 of 3008 potential participants took part in the study; this constituted 98% of those individuals approached and 55% of the persons enumerated in the local household registration system (hukou). Analyses revealed substantial differences among those who were interviewed during September and October 2005, versus those seen during the Chinese Lunar New Year of 2006 when many migrant workers and students returned to their homes. Both groups together differed from those who were unavailable during either recruiting episode. DISCUSSION AND CONCLUSIONS: We discuss potential responses to associated methodological challenges, including, (1) permanent hukou mismatches; (2) temporary hukou mismatches; (3) difficulties faced by potential participants to fully understand the purpose of research, the informed consent process, and specific research questions; and (4) appreciation of the importance of local social networks, as they pertain in particular to rural China. These findings underscore that there may be a need to make "on-the-ground" adjustments to varying local conditions to maximize sample representativeness and data validity.

    Changes in Arctic warming influence the various atmospheric and oceanic patterns that drive Caribbean and mid-latitude climate events, including extreme events like drought, tornadoes, and flooding in Kentucky and the surrounding region. Recently, the establishment of the North Atlantic Climate Change Collaboration (NAC3) project at Western Kentucky University (WKU) in partnership with the University of Akureyri (UNAK), Iceland Arctic Cooperation Network (IACN), and Caribbean Community Climate Change Centre (CCCCC) provides a foundation from which to engage students in applied research from the local to global levels and more clearly understand the many tenets of climate change impacts in the Arctic within both a global and local community context. The NAC3 project encompasses many facets, including joint international courses, student internships, economic development, service learning, and applied research. In its first phase, the project has generated myriad outcomes and opportunities for bridging STEM disciplines with other fields to holistically and collaboratively address specific human-environmental issues falling under the broad umbrella of climate change. WKU and UNAK students desire interaction and exposure to other cultures and regions that are threatened by climate change and Iceland presents a unique opportunity to study influences such as oceanic processes, island economies, sustainable harvest of fisheries, and Arctic influences on climate change. The project aims to develop a model to bring partners together to conduct applied research on the complex subject of global environmental change, particularly in the Arctic, while simultaneously focusing on changing how we learn, develop community, and engage internationally to understand the impacts and find solutions.

    The Ecosystem Dynamics Branch of the Fort Collins Science Center offers an interdisciplinary team of talented and creative scientists with expertise in biology, botany, ecology, geology, biogeochemistry, physical sciences, geographic information systems, and remote-sensing, for tackling complex questions about natural resources. As demand for natural resources increases, the issues facing natural resource managers, planners, policy makers, industry, and private landowners are increasing in spatial and temporal scope, often involving entire regions, multiple jurisdictions, and long timeframes. Needs for addressing these issues include (1) a better understanding of biotic and abiotic ecosystem components and their complex interactions; (2) the ability to easily monitor, assess, and visualize the spatially complex movements of animals, plants, water, and elements across highly variable landscapes; and (3) the techniques for accurately predicting both immediate and long-term responses of system components to natural and human-caused change. The overall objectives of our research are to provide the knowledge, tools, and techniques needed by the U.S. Department of the Interior, state agencies, and other stakeholders in their endeavors to meet the demand for natural resources while conserving biodiversity and ecosystem services. Ecosystem Dynamics scientists use field and laboratory research, data assimilation, and ecological modeling to understand ecosystem patterns, trends, and mechanistic processes. This information is used to predict the outcomes of changes imposed on species, habitats, landscapes, and climate across spatiotemporal scales. The products we develop include conceptual models to illustrate system structure and processes; regional baseline and integrated assessments; predictive spatial and mathematical models; literature syntheses; and frameworks or protocols for improved ecosystem monitoring, adaptive management, and program evaluation.

    The need for data curation is being recognized in numerous institutional settings as national research funding agencies extend data archiving mandates to cover more types of research grants. Data curation, however, is not only a practical challenge. It presents many conceptual and theoretical challenges that must be investigated to design appropriate technical systems, social practices and institutions, policies, and services. This presentation reports on outcomes from an investigation of research problems in data curation conducted as part of the Data Curation Education in Research Centers (DCERC) program. DCERC is developing a new model for educating data professionals to contribute to scientific research. The program is organized around foundational courses and field experiences in research and data centers for both master's and doctoral students. The initiative is led by the Graduate School of Library and Information Science at the University of Illinois at Urbana-Champaign, in collaboration with the School of Information Sciences at the University of Tennessee, and library and data professionals at the National Center for Atmospheric Research (NCAR). At the doctoral level DCERC is educating future faculty and researchers in data curation and establishing a research agenda to advance the field. The doctoral seminar, Research Problems in Data Curation, was developed and taught in 2012 by the DCERC principal investigator and two doctoral fellows at the University of Illinois. It was designed to define the problem space of data curation, examine relevant concepts and theories related to both technical and social perspectives, and articulate research questions that are either unexplored or under theorized in the current literature. There was a particular emphasis on the Earth and environmental sciences, with guest speakers brought in from NCAR, National Snow and Ice Data Center (NSIDC), and Rensselaer Polytechnic Institute.

  10. Applications of systems thinking and soft operations research in managing complexity from problem framing to problem solving

    CERN Document Server

    2016-01-01

    This book captures current trends and developments in the field of systems thinking and soft operations research which can be applied to solve today's problems of dynamic complexity and interdependency. Such ‘wicked problems’ and messes are seemingly intractable problems characterized as value-laden, ambiguous, and unstable, that resist being tamed by classical problem solving. Actions and interventions associated with this complex problem space can have highly unpredictable and unintended consequences. Examples of such complex problems include health care reform, global climate change, transnational serious and organized crime, terrorism, homeland security, human security, disaster management, and humanitarian aid. Moving towards the development of solutions to these complex problem spaces depends on the lens we use to examine them and how we frame the problem. It will be shown that systems thinking and soft operations research has had great success in contributing to the management of complexity. .

    A market driven economy has many effects on population growth. The laws of social production were explicated by Marx and Engels, and Comrade Deng Xiaoping presents his views on China's socialist market economy and population problems in this article. Modern market economies have changed greatly over time. Before the 1960s, the focus of the interaction between population and economic change was in macro control. Since the 1960s, the focus shifted to micro control. Theories on maximum growth and neomodern population theory provide only a few useful elements. Cost-benefit analysis of child production functions, despite limitations, has universal appeal. Western theories with sound scientific evidence and Marxist theories should be examined and integrated within the Chinese experience. Two areas of concern in China are the spatial imbalance between population and economic development and an appropriate time period for any research activity. Scientific research in China will be advanced by careful integration of theory and practice, careful study of the Chinese experience, in-depth analysis, and bold, practical approaches which incorporate existing research results from the West. There are three dominant views of economic reforms. 1) Economic development plans should include a market economy. 2) Chinese population control would depend upon administrative means rather than market forces. 3) There are indirect ways in which the market affects population production. The last position is favored. The conclusions are made that family planning has been and continues to be a driving force in declining birth rates and that a focus on government population control does not discount the importance of the influence of economic factors on changes in the birth rate. Market forces are beginning to show their impact on people's choice in reproduction, and the impact is increasing. Reforms must be made appropriate to both the position and the negative influence of the market economy on

    Full Text Available Abstract Purpose To identify the domains of quality of life important to people with mental health problems. Method A systematic review of qualitative research undertaken with people with mental health problems using a framework synthesis. Results We identified six domains: well-being and ill-being; control, autonomy and choice; self-perception; belonging; activity; and hope and hopelessness. Firstly, symptoms or ‘ill-being’ were an intrinsic aspect of quality of life for people with severe mental health problems. Additionally, a good quality of life was characterised by the feeling of being in control (particularly of distressing symptoms, autonomy and choice; a positive self-image; a sense of belonging; engagement in meaningful and enjoyable activities; and feelings of hope and optimism. Conversely, a poor quality life, often experienced by those with severe mental health difficulties, was characterized by feelings of distress; lack of control, choice and autonomy; low self-esteem and confidence; a sense of not being part of society; diminished activity; and a sense of hopelessness and demoralization. Conclusions Generic measures fail to address the complexity of quality of life measurement and the broad range of domains important to people with mental health problems.

    Urban living is the new reality for the majority of the world's population. Urban change is taking place in a context of other global challenges--economic globalization, climate change, financial crises, energy and food insecurity, old and emerging armed conflicts, as well as the changing patterns of communicable and noncommunicable diseases. These health and social problems, in countries with different levels of infrastructure and health system preparedness, pose significant development challenges in the 21st century. In all countries, rich and poor, the move to urban living has been both good and bad for population health, and has contributed to the unequal distribution of health both within countries (the urban-rural divide) and within cities (the rich-poor divide). In this series of papers, we demonstrate that urban planning and design and urban social conditions can be good or bad for human health and health equity depending on how they are set up. We argue that climate change mitigation and adaptation need to go hand-in-hand with efforts to achieve health equity through action in the social determinants. And we highlight how different forms of governance can shape agendas, policies, and programs in ways that are inclusive and health-promoting or perpetuate social exclusion, inequitable distribution of resources, and the inequities in health associated with that. While today we can describe many of the features of a healthy and sustainable city, and the governance and planning processes needed to achieve these ends, there is still much to learn, especially with respect to tailoring these concepts and applying them in the cities of lower- and middle-income countries. By outlining an integrated research agenda, we aim to assist researchers, policy makers, service providers, and funding bodies/donors to better support, coordinate, and undertake research that is organized around a conceptual framework that positions health, equity, and sustainability as central

    Full Text Available Abstract Background Most adolescents live in resource-constrained countries and their mental health has been less well recognised than other aspects of their health. The World Health Organization's 4-S Framework provides a structure for national initiatives to improve adolescent health through: gathering and using strategic information; developing evidence-informed policies; scaling up provision and use of health services; and strengthening linkages with other government sectors. The aim of this paper is to discuss how the findings of a recent systematic review of mental health problems in adolescents in resource-constrained settings might be applied using the 4-S Framework. Method Analysis of the implications of the findings of a systematic search of the English-language literature for national strategies, policies, services and cross-sectoral linkages to improve the mental health of adolescents in resource-constrained settings. Results Data are available for only 33/112 [29%] resource-constrained countries, but in all where data are available, non-psychotic mental health problems in adolescents are identifiable, prevalent and associated with reduced quality of life, impaired participation and compromised development. In the absence of evidence about effective interventions in these settings expert opinion is that a broad public policy response which addresses direct strategies for prevention, early intervention and treatment; health service and health workforce requirements; social inclusion of marginalised groups of adolescents; and specific education is required. Specific endorsed strategies include public education, parent education, training for teachers and primary healthcare workers, psycho-educational curricula, identification through periodic screening of the most vulnerable and referral for care, and the availability of counsellors or other identified trained staff members in schools from whom adolescents can seek assistance for

    Full Text Available In May 2016, two events epitomized the complexities of working for global transgender youth rights. First, United Nations Educational Scientific and Cultural Organisation (UNESCO hosted a ministerial event in which education ministers from around the world released a call to action for protection of students on the basis of their gender identity and expression in schools. Second, the United Nations (UN hosted an event celebrating the family, attended by conservative ministers and activists who mobilized family protectionist discourse against transgender students. This article contemplates, in light of transgender activist Raewyn Connell’s Southern Theory contributions, the complexity of global research and work for transgender youth. It considers key informant interviews with 50 stakeholders in the global push for transgender student rights in education, including members of government and non-government organisations, and academics from Northern and Southern countries. Problems in aiding transgender youth at the global level included safety concerns, the impacts of conservative advocates and media backlash (within family and national protectionist discourses, cultural complexities hampering engagement and translation, dissemination hindrances pertaining to established publishing biases, and financial and collaboration barriers. Solutions including virtual work; multi-level leadership; alliance-building; representation; visibility of transgender youth citizenship and family membership; and legal, financial and capacity-building aid are considered.

    The purpose of this research was to develop and pilot test an intervention to optimize functional recovery for breast cancer survivors. Over two studies, 31 women enrolled in a goal-setting program via telephone. All eligible women enrolled (37% of those screened) and 66% completed all study activities. Completers were highly satisfied with the intervention, using it to address, on average, four different challenging activities. The longitudinal analysis showed a main effect of time for overall quality of life (F(5, 43.1) = 5.1, p = 0.001) and improvements in active coping (F (3, 31.7) = 4.9, p = 0.007), planning (F (3, 36.0) = 4.1, p = 0.01), reframing (F (3, 29.3) = 8.5, p < 0.001), and decreases in self-blame (F (3,31.6) = 4.3, p = 0.01). The intervention is feasible and warrants further study to determine its efficacy in fostering recovery and maximizing activity engagement after cancer treatment.

    2017-01-01

    This paper discusses the importance of three features of psychometric tests for cognition research: construct definition, problem space, and knowledge domain. Definition of constructs, e.g., intelligence or creativity, forms the theoretical basis for test construction. Problem space, being well or ill-defined, is determined by the cognitive abilities considered to belong to the constructs, e.g., convergent thinking to intelligence, divergent thinking to creativity. Knowledge domain and the possibilities it offers cognition are reflected in test results. We argue that (a) comparing results of tests with different problem spaces is more informative when cognition operates in both tests on an identical knowledge domain, and (b) intertwining of abilities related to both constructs can only be expected in tests developed to instigate such a process. Test features should guarantee that abilities can contribute to self-generated and goal-directed processes bringing forth solutions that are both new and applicable. We propose and discuss a test example that was developed to address these issues.

    Full Text Available One year after the birth of the International Journal of MCH and AIDS (IJMA, we continue to share the passion to document, and shine the light on the myriads of global health issues that debilitate developing countries.Although the focus of IJMA is on the social determinants of health and disease as well as on the disparities in the burden of communicable and non-communicable diseases affecting infants, children, women, adults, and families in developing countries, we would like to encourage our fellow researchers and policy makers in both the developing and developed countries to consider submitting work that examines cross-national variations in heath and social inequalities.Such a global focus allows us to identify and understand social, structural, developmental, and health policy determinants underlying health inequalities between nations.Global assessment of health and socioeconomic patterns reaffirms the role of broader societal-level factors such as human development, gender inequality, gross national product, income inequality, and healthcare infrastructure as the fundamental determinants of health inequalities between nations.This is also confirmed by our analysis of the WHO data that shows a strong negative association between levels of human development and infant and maternal mortality rates.Focusing on socioeconomic, demographic, and geographical inequalities within a developing country, on the other hand, should give us a sense of how big the problem of health inequity is within its own borders.Such an assessment, then, could lead to development of policy solutions to tackle health inequalities that are unique to that country.

    We examined the uncertainty of the contextual influences on food access through an analytic framework of the uncertain geographic context problem (UGCoP). We first examined the compounding effects of two kinds of spatiotemporal uncertainties on people's everyday efforts to procure food and then outlined three key dimensions (food access in real time, temporality of the food environment, and perceived nutrition environment) in which research on food access must improve to better represent the contributing environmental influences that operate at the individual level. Guidelines to address the UGCoP in future food access research are provided to account for the multidimensional influences of the food environment on dietary behaviors.

    In order to study graduate teaching assistants (TAs) beliefs and values about the design of instructor problem solutions, twenty-four TAs were provided with different solutions and asked to discuss their preferences for prominent solution features. TAs preferences for solution features were examined in light of the modeling of expert-like problem solving process as recommended in the literature. Results suggest that while many of the features TAs valued align with expert-like problem solving approaches, they noticed primarily "surface features" of solutions. Moreover, self-reported preferences did not match well with the solutions TAs wrote on their own.

    The authors surveyed 21 editors and reviewers from major psychology journals to identify and describe the statistical and design errors they encounter most often and to get their advice regarding prevention of these problems. Content analysis of the text responses revealed themes in 3 major areas: (a) problems with research design and reporting (e.g., lack of an a priori power analysis, lack of congruence between research questions and study design/analysis, failure to adequately describe statistical procedures); (b) inappropriate data analysis (e.g., improper use of analysis of variance, too many statistical tests without adjustments, inadequate strategy for addressing missing data); and (c) misinterpretation of results. If researchers attended to these common methodological and analytic issues, the scientific quality of manuscripts submitted to high-impact psychology journals might be significantly improved.

    Full Text Available The global sociology currently faces one of its greatest challenges: to contribute to the debate about the most serious problem which all societies have faced in recent years. The rising inequality has led to many initiatives for reflection, discussion and evaluation of public policies in order to combat poverty. Particularly, the fact that the Millennium Goals are supposed to accomplish their significance by 2015 provides the International Sociological Association (ISA the unique opportunity to contribute to those goals through their own analyses and proposals. Over many years, the ISA has promoted the integrated debate of its members on issues related to inequalities: from different perspectives such as education, health, social movements, public policies, gender problems and violence, among others. The overlapping and accumulation of inequalities has been, so to speak, the natural environment from which the ISA can take part in this international debate. This article identifies the work lines approved in the Association Program Committee Meeting held in Mexico in 2011, in the process of theAssociation’s Congress in Yokohama in 2014.

    Bauer, Travis LaDell

    2009-12-01

    This paper has three goals. The first is to review Shannon's theory of information and the subsequent advances leading to today's statistics-based text analysis algorithms, showing that the semantics of the text is neglected. The second goal is to propose an extension of Shannon's original model that can take into account semantics, where the 'semantics' of a message is understood in terms of the intended or actual changes on the recipient of a message. The third goal is to propose several lines of research that naturally fall out of the proposed model. Each computational approach to solving some problem rests on an underlying model or set of models that describe how key phenomena in the real world are represented and how they are manipulated. These models are both liberating and constraining. They are liberating in that they suggest a path of development for new tools and algorithms. They are constraining in that they intentionally ignore other potential paths of development. Modern statistical-based text analysis algorithms have a specific intellectual history and set of underlying models rooted in Shannon's theory of communication. For Shannon, language is treated as a stochastic generator of symbol sequences. Shannon himself, subsequently Weaver, and at least one of his predecessors are all explicit in their decision to exclude semantics from their models. This rejection of semantics as 'irrelevant to the engineering problem' is elegant and combined with developments particularly by Salton and subsequently by Latent Semantic Analysis, has led to a whole collection of powerful algorithms and an industry for data mining technologies. However, the kinds of problems currently facing us go beyond what can be accounted for by this stochastic model. Today's problems increasingly focus on the semantics of specific pieces of information. And although progress is being made with the old models, it seems natural to develop or

    Comparison of modern submarine fans and ancient turbidite sequences is still in its infancy, mainly because of the incompatibility of study approaches. Research on modern fan systems mainly deals with morphologic aspects and surficial sediments, while observations on ancient turbidite formations are mostly directed to vertical sequences. The lack of a common data set also results from different scales of observation. To review the current status of modern and ancient turbidite research, an international group of specialists formed COMFAN (Committee on Fans) and met in September 1982 at the Gulf Research and Development Company research facilities in Pennsylvania. ?? 1984 Springer-Verlag New York Inc.

    Ladies and Gentlemen, It is an honor for me to present my welcome address in the 3rd International Workshop on "State of the Art in Nuclear Cluster Physics"(SOTANCP3), as the president of Kanto Gakuin University. Particularly to those from abroad more than 17 countries, I am very grateful for your participation after long long trips from your home to Yokohama. On the behalf of the Kanto Gakuin University, we certainly welcome your visit to our university and stay in Yokohama. First I would like to introduce Kanto Gakuin University briefly. Kanto Gakuin University, which is called KGU, traces its roots back to the Yokohama Baptist Seminary founded in 1884 in Yamate, Yokohama. The seminary's founder was Albert Arnold Bennett, alumnus of Brown University, who came to Japan from the United States to establish a theological seminary for cultivating and training Japanese missionaries. Now KGU is a major member of the Kanto Gakuin School Corporation, which is composed of two kindergartens, two primary schools, two junior high schools, two senior high schools as well as KGU. In this university, we have eight faculties with graduate school including Humanities, Economics, Law, Sciences and Engineering, Architecture and Environmental Design, Human and Environmental Studies, Nursing, and Law School. Over eleven thousands students are currently learning in our university. By the way, my major is the geotechnical engineering, and I belong to the faculty of Sciences and Engineering in my university. Prof. T. Yamada, here, is my colleague in the same faculty. I know that the nuclear physics is one of the most active academic fields in the world. In fact, about half of the participants, namely, more than 50 scientists, come from abroad in this conference. Moreover, I know that the nuclear physics is related to not only the other fundamental physics such as the elementary particle physics and astrophysics but also chemistry, medical sciences, medical cares, and radiation metrology

    @@In the combinatorial geometry of convex sets the question of how efficiently a family of convex sets can be pierced by points has led to various problems which may be regarded as extensions of the Helly-type problems. A family of sets is said to be n-pierceable (abbreviated as Пn) if there exists a set of n points such that each member of the family contains at least one of them. A family of sets is said to be Пnk if every subfamily of size k or less is Пn. The famous Helly theorem in combinatorial geometry asserts that for finite families of convex sets in the plane П13 implies П1. In a recent paper by M. Katchalski and D. Nashtir[a] the following conjecture of Griinbaum[2] was mentioned again:

This distinguished gathering of experts in the vast field of modern methods for archiving and managing almost infinite astronomical data files of everlasting value will doubtlessly make a considerable and important contribution to success in the present and future research in astronomy. All of us are witnesses of a great technological, even psychological upturn that occurs in the everyday astronomical practice. The small but the most powerful handy devices known as desktop, laptop, or even palm-top PCs, have rendered a tedious calculating work and stressing search in the card-file or book-form catalogs to a pure pleasure and raised an admiration for those brilliant minds that have invented such a kind of hard- and software. The networks of all kinds and sorts -- Internet, Bitnet, World Wide Web, etc. -- have realized ancient dreams of a Man to fly with thought all over the world communicating with other human beings. But ... don't forget that the most real and valuable communication is the live one, when one can see the face and the eyes of his (or her) partner, listen to his voice as large as life, and the only opportunity for this is to stay together. And this just occurs at the colloquium like ours! So, let me heartily welcome you to the Pulkovo Observatory.

    The greenhouse gas emissions of international aviation and maritime transport are projected to increase rapidly over the coming decades, despite significant improvements in the fuel efficiency of aircraft and ships. In order to address their growth, Market Based Measures (MBMs) have been proposed to complement technical and operational measures. These measures are being discussed in ICAO (the UN organization for civil aviation) and IMO (the UN organization for maritime transport). One of the main issues in the debate has been the impact of MBMs on developing countries and especially on remote economies. This report quantifies the economic impacts of MBMs on ten case study economies and globally. The case study economies have been selected in the expectation that they would be relatively highly impacted because of their remoteness and/or dependence on international aviation or maritime transport. This report shows that the decrease in GDP is less than 0.01% on average and significantly less than 0.1% for all but a few of the case study countries. Countries with a higher dependency on tourism and trade are likely to experience greater economic impacts as market-based measures raise the costs of aviation and maritime transport; they impact economies due to increased prices for passenger travel and exported and imported goods. Some of these countries are small island states that are also vulnerable to climate change impacts. Undesired economic impacts on developing countries can be addressed effectively by a combination of measures such as exemptions of certain routes, lump sum rebates, and investments in infrastructure efficiency and development of more efficient ships and aircraft.

    Ladies and Gentlemen To quote Mr Jean Terrien: "Physics must be one step ahead of metrology". A long-serving Director of the BIPM, he said these words when visiting the IMGC in 1970 as a member of the scientific board of our Institute. At that time it was still an open question whether the IMGC should start research work on the absolute measurement of silicon lattice spacing. Mr Terrien underlined the revolutionary character of x-ray interferometry and, eventually, he caused the balance needle to lean towards the ... right direction. Mr Terrien correctly foresaw that, like Michelson's interferometer of 1880, x-ray interferometry could have a prominent place in today's science and technology. And while, in the first case, after more than a century we can see instruments based on electromagnetic wave interaction within every one's reach in laboratories and, sometimes, in workshops, in the second case, twenty-five years since the first development of an x-ray interferometer we can witness its role in nanometrology. Today and tomorrow we meet to discuss how to go beyond the sixth decimal place in the value of the Avogadro constant. We are aware that the quest for this achievement requires the cooperation of scientists with complementary capabilities. I am sure that the present workshop is a very good opportunity to present and discuss results and to improve and extend existing cooperation. The new adjustment of fundamental constants envisaged by the CODATA Task Group is redoubling scientists' efforts to produce competitive values of NA. The results of the measurements of the silicon lattice spacing in terms of an optical wavelength, which were available for the 1986 adjustment, combined with the determination of silicon molar volume, demonstrate how such an NA determination produces a consistent set of other constants and opens the way to a possible redefinition of the kilogram. We shall see in these two days how far we have progressed along this road. For us at the

Because of this cognitive function we can analyze the development of processes and objects. It also determines the possibilities for the creative transformation of some content and for solving problems. The article presents a description and the results of experimental studies. This evidence proves that dialectical thinking is a specific line of cognitive development in children and adults. This line can degrade during school time if the educational program follows formal logical principles, or it can become significantly stronger if the pedagogy is based on dialectical methodology.

    In our current moment, there is considerable interest in networks, in how people and things are connected. This essay outlines one approach that brings together insights from actor-network theory, social network analysis, and digital history to interpret past scientific activity. Multispecies network analysis (MNA) is a means of understanding the historical interactions among scientists, institutions, and preferred experimental animals. A reexamination of studies of sexual behavior funded by the Committee for Research in Problems of Sex between the 1920s and the 1940s demonstrates the applicability of MNA to clarifying the relations that sustained this area of psychology. The measures of weighted degree and betweenness can highlight which nodes (whether organisms or institutions) were particularly "central" to this network. Rats featured as the animals most widely studied during this period, but the analysis also reveals distinct institutional and disciplinary cultures where different species were favored as either surrogates for humans or representatives of more general biological groups.

    Gauge mediated supersymmetry (SUSY)-breaking (GMSB) furnishes the best idea to overcome the flavor problem in SSMs, supersymmetric stand models (SM). However, implemented in the minimal SSM (MSSM), a very serious fine-tuning problem arises, owing to the absence of a large $A_t$ term in the stop sector to radiatively enhance the SM-like Higgs boson mass. In the extended GMSB coupling $H_u$ to messengers can alleviate this problem but encounters the $A_t/m_{H_u}^2$ problem, i.e., at the same time a large $m_{H_u}^2$ is generated, rendering radiative electroweak spontaneously breaking (EWSB) problematic. This issue shows similarity to another long-standing problem of GMSB, the $\\mu/{B_\\mu }$ problem, and, of great interest, we find that they may admit the same solution, nonradiative EWSB. Such a solution is naturally accommodated when both $H_u$ and $H_d$ couple to messengers. As a bonus of nonradiative EWSB, the sleptons tend to be very light due to the significant renormalization group equation effect and they...

    Sensing principles and main problems to be solved for optical voltage sensors are briefly reviewed. Optical effects used for voltage sensing usually include electro-optic Pockels and Kerr effects, electro-gyration effect, elasto-optical effect, and electroluminescent effects, etc. In principle, typical optical voltage sensor is based on electro-optic Pockels crystals and closed-loop signal detection scheme. Main problems to be solved for optical voltage sensors include: how to remove influence of unwanted multiple optical effects on voltage sensing performance; how to select or develop a proper voltage sensing material and element; how to keep optical phase bias to be stable under temperature fluctuation and vibration; how to achieve dc voltage sensing, etc. In order to suppress the influence of unwanted optical effects and light beam coupling-related loss on voltage sensing signals, we may pay more attention to all-fiber and waveguide voltage sensors. Voltage sensors based on electroluminescent effects are also promising in some application fields due to their compact configuration, low cost and potential long-term reliability.

    Kia-Keating, Maryam; Santacrose, Diana E; Liu, Sabrina R; Adams, Jessica

    High rates of exposure to violence and other adversities among Latino/a youth contribute to health disparities. The current article addresses the ways in which community-based participatory research (CBPR) and human-centered design (HCD) can help engage communities in dialogue and action. We present a project exemplifying how community forums, with researchers, practitioners, and key stakeholders, including youths and parents, integrated HCD strategies with a CBPR approach. Given the potential for power inequities among these groups, CBPR + HCD acted as a catalyst for reciprocal dialogue and generated potential opportunity areas for health promotion and change. Future directions are described.

    The increasing complexity of scientific research has been followed by increasing varieties of research misconduct. Dealing with misconduct involves the processes of detection, reporting, and investigation of misconduct. Each of these steps is associated with numerous problems which need to be addressed. Misconduct investigation should not stop with inquiries and disciplinary actions in specific episodes of misconduct. It is necessary to decrease the personal price paid by those who expose misconduct and to protect the personal and professional interests of honest researchers accused of misconduct unfairly or mistakenly. There is no dearth of suggestions to improve the objectivity and fairness of investigations. What is needed is the willingness to test the various options and implement the most suitable ones.

  8. Mixed Methods Research: The "Thing-ness" Problem.

    Science.gov (United States)

    Hesse-Biber, Sharlene

    2015-06-01

    Contemporary mixed methods research (MMR) veers away from a "loosely bounded" to a "bounded" concept that has important negative implications for how qualitatively driven mixed methods approaches are positioned in the field of mixed methods and overall innovation in the praxis of MMR. I deploy the concept of reification defined as taking an object/abstraction and treating it as if it were real such that it takes on the quality of "thing-ness," having a concrete independent existence. I argue that the contemporary reification of mixed methods as a "thing" is fueled by three interrelated factors: (a) the growing formalization of mixed methods as design, (b) the unexamined belief in the "synergy" of mixed methods and, (c) the deployment of a "practical pragmatism" as the "philosophical partner" for mixed methods inquiry.

  9. Mathematical models of physics problems (physics research and technology)

    CERN Document Server

    Anchordoqui, Luis Alfredo

    2013-01-01

    This textbook is intended to provide a foundation for a one-semester introductory course on the advanced mathematical methods that form the cornerstones of the hard sciences and engineering. The work is suitable for first year graduate or advanced undergraduate students in the fields of Physics, Astronomy and Engineering. This text therefore employs a condensed narrative sufficient to prepare graduate and advanced undergraduate students for the level of mathematics expected in more advanced graduate physics courses, without too much exposition on related but non-essential material. In contrast to the two semesters traditionally devoted to mathematical methods for physicists, the material in this book has been quite distilled, making it a suitable guide for a one-semester course. The assumption is that the student, once versed in the fundamentals, can master more esoteric aspects of these topics on his or her own if and when the need arises during the course of conducting research. The book focuses on two cor...

    2015-02-01

    This is the second of two closely related articles (Paper I and Paper II) that together illustrate how research in physics education has helped guide the design of instruction that has proved effective in improving student understanding of atomic spectroscopy. Most of the more than 1000 students who participated in this four-year investigation were science majors enrolled in the introductory calculus-based physics course at the University of Washington (UW) in Seattle, WA, USA. The others included graduate and undergraduate teaching assistants at UW and physics majors in introductory and advanced physics courses at the University of Zagreb, Zagreb, Croatia. About half of the latter group were preservice high school physics teachers. Paper I describes how several conceptual and reasoning difficulties were identified among university students as they tried to relate a discrete line spectrum to the energy levels of atoms in a light source. This second article (Paper II) illustrates how findings from this research informed the development of a tutorial that led to improvement in student understanding of atomic emission spectra.

    2016-11-19

    There is at present a huge disconnect between levels of funding for basic research on fundamental mechanisms of biological aging and, given demographic projections, the anticipated enormous social and economic impacts of a litany of chronic diseases for which aging is by far the major risk factor: One valuable approach, recently instigated by Felipe Sierra & colleagues at the US National Institute on Aging, is the development of a Geroscience Interest Group among virtually all of the NIH institutes. A complementary approach would be to seek major escalations of private funding. The American Federation for Aging Research, the Paul Glenn Foundation and the Ellison Medical Foundation pioneered efforts by the private sector to provide substantial supplements to public sources of funding. It is time for our community to organize efforts towards the enhancements of such crucial contributions, especially in support of the emerging generation of young investigators, many of whom are leaving our ranks to seek alternative employment. To do so, we must provide potential donors with strong economic, humanitarian and scientific rationales. An initial approach to such efforts is briefly outlined in this manuscript as a basis for wider discussions within our community.

    In this proceedings we will present a research project financed by Piedmont regional government (Italy; finalized to the realization and commercialization of functional devices for cellular bio-sensing based on diamond. Partners of the project are: Crisel Instruments, Torino University, Torino Polytechnic, INRIM, Politronica, Bionica Tech, Ulm University Here the main features of the final devices will be briefly summarized. We envisage an active diamond-based cellular substrate that can simultaneously stimulate and detect a variety of signals (chemical, optical, electrical) to and from neuroendocrine cells, in a fully biocompatible environment for the cellular system under test. Such a device can be realized by fully exploiting the peculiar properties of diamond: optical transparency, biocompatibility, chemical inertness, accessibility to a conductive graphite-like phase; properties that will be further explored and tested during the project.

  14. Lingua-Pedagogy as the Interdisciplinary Research Problem

    Directory of Open Access Journals (Sweden)

    2012-01-01

    Full Text Available  The paper is devoted to lingua-pedagogy – one of the modern branches of pedagogy dealing with personal socialization in the process of foreign language learning. This interdisciplinary field of knowledge is related to linguistics, pedagogic psychology, development psychology and acmeology. Lingua-pedagogy undergoes the formation process; therefore, there still are a number of open questions concerning its place among the other sciences, and the final definitions of the main concepts and terms. The author recommends the systematic approach to developing the theoretical foundation of lingua- pedagogy. The paper outlines the subject and aims of the lingua-pedagogic research, its content and affecting means. The system in question is poly- functional, its main functions being the integral pedagogic effect in foreign language teaching, stimulating self-dependent learning, and arranging the in- tercultural integration. The linguistic faculties at universities can be taken as the key elements of the lingua-pedagogic system – the development centers, nurturing the value-oriented respectful attitude to the native and foreign cul- ture, providing intercultural competence acquisition, and training pedagogic staff capable of fulfilling the poly-cultural development tasks. Identification of the conformities of intercultural socialization makes it possible to organize the system of pedagogic facilitation for students learning foreign languages; and develop the perspective methods and technologies of language competence acquisition and consolidation.

    2011-01-01

    This study explores how adult survivors of chronic abuse and neglect define pleasure, the disruption of pleasure, and the repair of the capacity for pleasure in the context of the therapeutic relationship. Using narrative methodology, I interviewed 15 clinical pairs of patients and their therapists separately. Thematic analysis revealed 8 findings. All patients reported the capacity to experience pleasure throughout life prior to therapy. Subjects defined pleasure as a variety of positive affects that fell into 2 categories: pleasure in activities and interests and pleasure in relationships. All patients reported a history of traumatic disruption of pleasure in childhood. Patients reported a history of internalizing and reenacting their own disruption of pleasure. Narratives of the patients were consistent with the narratives told by the therapists. In many clinical pairs, both parties spoke positively of an important therapeutic event when the therapist stepped out of his or her usual treatment frame. Safety, consistency, reliability, predictability, and compassionate caring were spoken of throughout the sample as elements that created a pleasurable and therapeutically reparative relationship. Patients spoke repeatedly of the importance of "finding a self" to the experience of pleasure. Pleasure enhanced the ability to find a self, and finding a self enhanced patients' capacity for pleasure. This study invites further research to investigate the function of pleasure in the process of therapeutic repair for chronically traumatized populations.

    The basic concepts and models of weapon-target assignment (WTA) are introduced and the mathematical nature of the WTA models is also analyzed. A systematic survey of research on WTA problem is provided. The present research on WTA is focused on models and algorithms. In the research on models of WTA, the static WTA models are mainly studied and the dynamic WTA models are not fully studied in deed. In the research on algorithms of WTA, the intelligent algorithms are often used to solve the WTA problem. The small scale of static WTA problems has been solved very well, however, the large scale of dynamic WTA problems has not been solved effectively so far. Finally, the characteristics of dynamic WTA are analyzed and directions for the future research on dynamic WTA are discussed.

    Full Text Available Abstract Background Policy makers, clinicians and researchers are demonstrating increasing interest in using data linked from multiple sources to support measurement of clinical performance and patient health outcomes. However, the utility of data linkage may be compromised by sub-optimal or incomplete linkage, leading to systematic bias. In this study, we synthesize the evidence identifying participant or population characteristics that can influence the validity and completeness of data linkage and may be associated with systematic bias in reported outcomes. Methods A narrative review, using structured search methods was undertaken. Key words "data linkage" and Mesh term "medical record linkage" were applied to Medline, EMBASE and CINAHL databases between 1991 and 2007. Abstract inclusion criteria were; the article attempted an empirical evaluation of methodological issues relating to data linkage and reported on patient characteristics, the study design included analysis of matched versus unmatched records, and the report was in English. Included articles were grouped thematically according to patient characteristics that were compared between matched and unmatched records. Results The search identified 1810 articles of which 33 (1.8% met inclusion criteria. There was marked heterogeneity in study methods and factors investigated. Characteristics that were unevenly distributed among matched and unmatched records were; age (72% of studies, sex (50% of studies, race (64% of studies, geographical/hospital site (93% of studies, socio-economic status (82% of studies and health status (72% of studies. Conclusion A number of relevant patient or population factors may be associated with incomplete data linkage resulting in systematic bias in reported clinical outcomes. Readers should consider these factors in interpreting the reported results of data linkage studies.

  3. Impact of problem finding on the quality of authentic open inquiry science research projects

    Science.gov (United States)

    Labanca, Frank

    2008-11-01

    Problem finding is a creative process whereby individuals develop original ideas for study. Secondary science students who successfully participate in authentic, novel, open inquiry studies must engage in problem finding to determine viable and suitable topics. This study examined problem finding strategies employed by students who successfully completed and presented the results of their open inquiry research at the 2007 Connecticut Science Fair and the 2007 International Science and Engineering Fair. A multicase qualitative study was framed through the lenses of creativity, inquiry strategies, and situated cognition learning theory. Data were triangulated by methods (interviews, document analysis, surveys) and sources (students, teachers, mentors, fair directors, documents). The data demonstrated that the quality of student projects was directly impacted by the quality of their problem finding. Effective problem finding was a result of students using resources from previous, specialized experiences. They had a positive self-concept and a temperament for both the creative and logical perspectives of science research. Successful problem finding was derived from an idiosyncratic, nonlinear, and flexible use and understanding of inquiry. Finally, problem finding was influenced and assisted by the community of practicing scientists, with whom the students had an exceptional ability to communicate effectively. As a result, there appears to be a juxtaposition of creative and logical/analytical thought for open inquiry that may not be present in other forms of inquiry. Instructional strategies are suggested for teachers of science research students to improve the quality of problem finding for their students and their subsequent research projects.

    Global climate change is a serious environmental concern, and the US has developed An Action Agenda'' to deal with it. At the heart of the US effort is the US Global Change Research Program (USGCRP), which has been developed by the Committee on Earth and Environmental Sciences (CEES) of the Federal Coordinating Council for Sciences, Engineering, and Technology (FCCSET). The USGCRP will provide the scientific basis for sound policy making on the climate-change issue. The DOE contribution to the USGCRP is the Carbon Dioxide Research Program, which now places particular emphasis on the rapid improvement of the capability to predict global and regional climate change. DOE's Carbon Dioxide Research Program has been addressing the carbon dioxide-climate change connection for more than twelve years and has provided a solid scientific foundation for the USGCRP. The expansion of the DOE effort reflects the increased attention that the Department has placed on the issue and is reflected in the National Energy Strategy (NES) that was released in 1991. This Program Summary describes projects funded by the Carbon Dioxide Research Program during FY 1991 and gives a brief overview of objectives, organization, and accomplishments. The Environmental Sciences Division of the Office of Health and Environmental Research, Office of Energy Research supports a Carbon Dioxide Research Program to determine the scientific linkage between the rise of greenhouse gases in the atmosphere, especially carbon dioxide, and climate and vegetation change. One facet is the Core CO{sub 2} Program, a pioneering program that DOE established more than 10 years ago to understand and predict the ways that fossil-fuel burning could affect atmospheric CO{sub 2} concentration, global climate, and the Earth's biosphere. Major research areas are: global carbon cycle; climate detection and models of climate change; vegetation research; resource analysis; and, information and integration.

    本文主要就向量地址平均长度问题进行建模与仿真。向量网很好地解决了IP网络地址枯竭的问题,但由于向量地址是不定长的,因此对向量地址平均长度的研究成为评价向量网效率的一个重要方面。本文利用BRITE网络拓扑生成器,分别利用Waxman随机图模型和BA无标度模型,针对不同节点和边数的网络拓扑进行仿真实验,并对不同实验结果进行对比与分析。实验结果表明,向量地址平均长度会随节点数增长而增长,但在较大规模网络拓扑中,向量地址平均长度远远小于IP地址长度。%This paper mainly describes modeling and simulation on average length of vector address. Vector network solves the problem of limited amount of address of IP network, but for the uncertainty of its length, research on average length of vector address becomes an important aspect to evaluate the efficiency of vector network. In this paper, we generate network topology with Waxman model and BA scale-free model with different amount of nodes and edges using BRITE. Then, we make comparison and analysis of the simulation. The result shows that average length of vector address increases with the amount of nodes, but its length is far shorter than the length of IP network.

    2014-02-01

    Nursing in France is undergoing a transition. In 2009, the preregistration nursing education program was reformed in line with the European Bologna Process, bringing nursing education to the universities. In 2010, the French Programme Hospitalier de Recherche Infirmière, the first national French nursing research funding program, was launched by the French Health Ministry. Of the 149 French research proposals submitted by registered nurses in 2010 and 2011, 13 were mixed-method proposals. The registered nurse principal investigator argued for a complementary use of qualitative and quantitative methods. These trends highlight major issues regarding mixed-method and nursing research. We can reasonably assume that mixed-method research has a broad appeal for nurse scholars, particularly for the exploration of complex phenomena related to nursing. Moreover, the recent movement in the domain of nursing education and research experienced in France highlights the need for dedicated research education in the development of nursing research capacity.

  13. Language and rigour in qualitative research: problems and principles in analyzing data collected in Mandarin.

    Science.gov (United States)

    Smith, Helen J; Chen, Jing; Liu, Xiaoyun

    2008-07-10

    In collaborative qualitative research in Asia, data are usually collected in the national language, and this poses challenges for analysis. Translation of transcripts to a language common to the whole research team is time consuming and expensive; meaning can easily be lost in translation; and validity of the data may be compromised in this process. We draw on several published examples from public health research conducted in mainland China, to highlight how language can influence rigour in the qualitative research process; for each problem we suggest potential solutions based on the methods used in one of our research projects in China. Problems we have encountered include obtaining sufficient depth and detail in qualitative data; deciding on language for data collection; managing data collected in Mandarin; and the influence of language on interpreting meaning. We have suggested methods for overcoming problems associated with collecting, analysing, and interpreting qualitative data in a local language, that we think help maintain analytical openness in collaborative qualitative research. We developed these methods specifically in research conducted in Mandarin in mainland China; but they need further testing in other countries with data collected in other languages. Examples from other researchers are needed.

  15. Analysis of current research addressing complementary use of life-cycle assessment and risk assessment for engineered nanomaterials: have lessons been learned from previous experience with chemicals?

[Technical University of Denmark, Department of Management Engineering (Denmark)

    2012-07-15

    While it is generally agreed that successful strategies to address the health and environmental impacts of engineered nanomaterials (NM) should consider the well-established frameworks for conducting life-cycle assessment (LCA) and risk assessment (RA), scientific research, and specific guidance on how to practically apply these methods are still very much under development. This paper evaluates how research efforts have applied LCA and RA together for NM, particularly reflecting on previous experiences with applying these methods to chemicals. Through a literature review and a separate analysis of research focused on applying LCA and RA together for NM, it appears that current research efforts have taken into account some key 'lessons learned' from previous experience with chemicals while many key challenges remain for practically applying these methods to NM. We identified two main approaches for using these methods together for NM: 'LC-based RA' (traditional RA applied in a life-cycle perspective) and 'RA-complemented LCA' (conventional LCA supplemented by RA in specific life-cycle steps). Hence, the latter is the only identified approach which genuinely combines LC- and RA-based methods for NM-risk research efforts to date as the former is rather a continuation of normal RA according to standard assessment procedures (e.g., REACH). Both these approaches along with recommendations for using LCA and RA together for NM are similar to those made previously for chemicals, and thus, there does not appear to be much progress made specific for NM. We have identified one issue in particular that may be specific for NM when applying LCA and RA at this time: the need to establish proper dose metrics within both methods.

  16. How can we improve problem-solving in undergraduate biology? Applying lessons from 30 years of physics education research

    CERN Document Server

    Hoskinson, Anne-Marie; Knight, Jennifer K

    2012-01-01

    Modern biological problems are complex. If students are to successfully grapple with such problems as scientists and citizens, they need to have practiced solving authentic, complex problems during their undergraduate years. Physics education researchers have investigated student problem-solving for the last three decades. Although the surface features and content of biology problems differ from physics problems, teachers of both sciences want students to learn to explain patterns and processes in the natural world and to make predictions about system behaviors. After surveying literature on problem-solving in physics and biology, we propose how biology education researchers could apply research-supported pedagogical techniques from physics to enhance biology students' problem-solving. First, we characterize the problems that biology students are typically asked to solve. We then describe the development of research-validated physics problem-solving curricula. Finally, we propose how biology scholars can appl...

    The number of gas-dynamic events per million tons of coal mined remains great though coal output from underground coal mines in Donetsk basin has dropped. This dictates enhanced research efforts to solve the following gas-dynamic problems: sudden coal, rock and gas outbursts, sudden coal, rock and gas outbursts, sudden squeezing, falls (coal spillage) sudden methane inrushes from the bottom, and bumps. New approaches to solve these problems have been based on modern concepts and ideas of natural mechanisms of the events. Current and future research needs are discussed. 7 refs., 3 figs., 2 tabs.

    1. Poultry disease research in the UK began recognisably in the 1920s, in consequence of the development of a national poultry industry of economic importance. 2. Increasing disease problems during the 1930s revealed the need for more research, resulting notably in the growth of the Poultry Department of the Central Veterinary Laboratory and the establishment of Houghton Poultry Research Station. 3. Continued growth of the egg industry and the introduction of the broiler industry in the 1950s stimulated increased disease research, much of it publicly funded, during the following two decades. 4. Changing government attitudes to agricultural research in the 1980s brought about far-reaching changes to the funding, organisation, nature and amount of disease research conducted. Arrangements for such research continue to evolve.

    Full Text Available The purpose of this study was to illustrate the application of A3 Problem Solving Reports of the Toyota Production System to our research vivarium through the methodology of Continuous Performance Improvement, a lean approach to healthcare management at Seattle Children's (Hospital, Research Institute, Foundation. The Report format is described within the perspective of a 10-step scientific method designed to realize measurable improvements of Issues identified by the Report's Author, Sponsor and Coach. The 10-step method (Issue, Background, Current Condition, Goal, Root Cause, Target Condition, Countermeasures, Implementation Plan, Test, and Follow-up was shown to align with Shewhart's Plan-Do-Check-Act process improvement cycle in a manner that allowed for quantitative analysis of the Countermeasure's outcomes and of Testing results. During fiscal year 2012, 9 A3 Problem Solving Reports were completed in the vivarium under the teaching and coaching system implemented by the Research Institute. Two of the 9 reports are described herein. Report #1 addressed the issue of the vivarium's veterinarian not being able to provide input into sick animal cases during the work day, while report #7 tackled the lack of a standard in keeping track of weekend/holiday animal health inspections. In each Report, a measurable Goal that established the basis for improvement recognition was present. A Five Whys analysis identified the Root Cause for Report #1 as historical work patterns that existed before the veterinarian was hired on and that modern electronic communication tools had not been implemented. The same analysis identified the Root Cause for Report #7 as the vivarium had never standardized the process for weekend/holiday checks. Successful outcomes for both Reports were obtained and validated by robust audit plans. The collective data indicate that vivarium staff acquired a disciplined way of reporting on, as well as solving, problems in a manner

    Transfer of knowledge across the science-society interface is essential for both, ethical and economic reasons, and inevitable for successful climate change adaptation and integrated management of sustainable, resilient landscapes. The transdisciplinary research of connectivity (which is the degree to which a system facilitates the movement of matter and energy through itself. It is an emergent property of the system state, Connecteur web resources,2015) has the potential to supply monitoring, modelling and management tools to land and water managers in order to reach these goals. The research of water and sediment connectivity has received significant and increasing scientific attention across the entire realm of the environmental disciplines, and the COST Action ES 1306 Connecteur facilitates the multi-sectorial collaboration in connectivity research at EU level. In order to appropriately address the transfer of the cutting edge research developments of the Connecteur network, the collaborative research project on stakeholders' perception of connectivity was conducted by the Working Group 5 "Transition of connectivity research towards sustainable land and water management". The questionnaire survey on stakeholder perception was conducted by volunteering scientist involved in the Connecteur network together from 19 European countries. Together 84 stakeholders from all mayor sectors in water and land management were asked about the main challenges of their work, their understanding of connectivity, the desired areas of cooperation with connectivity science, and the best tools for transferring knowledge. The results showed differences between different stakeholders groups in the way they percept and work with connectivity, as well as their requirement of knowledge transfers. While farmers, and (in lower extend) the agricultural administration officers articulated no, or little need for connectivity management, the majority of stakeholders involved in land and water

    Full Text Available This research focuses on the Hybrid Flow Shop production scheduling problem, which is one of the most difficult problems to solve. The literature points to several studies that focus the Hybrid Flow Shop scheduling problem with monocriteria functions. Despite of the fact that, many real world problems involve several objective functions, they can often compete and conflict, leading researchers to concentrate direct their efforts on the development of methods that take consider this variant into consideration. The goal of the study is to review and analyze the methods in order to solve the Hybrid Flow Shop production scheduling problem with multicriteria functions in the literature. The analyses were performed using several papers that have been published over the years, also the parallel machines types, the approach used to develop solution methods, the type of method develop, the objective function, the performance criterion adopted, and the additional constraints considered. The results of the reviewing and analysis of 46 papers showed opportunities for future research on this topic, including the following: (i use uniform and dedicated parallel machines, (ii use exact and metaheuristics approaches, (iv develop lower and uppers bounds, relations of dominance and different search strategies to improve the computational time of the exact methods,  (v develop  other types of metaheuristic, (vi work with anticipatory setups, and (vii add constraints faced by the production systems itself.

    Changing climate conditions may have beneficial or adverse effects on the social-ecological systems we are living in. In any case, the possible effects result from complex and interlinked physical and social processes embedded in these systems. Traditional research addresses these bio-physical and societal issues in a separate way. Therefore, in general, studies on risks related to climate change are still mono-disciplinary in nature with an increasing amount of work following a multi-disciplinary approach. The quality and usefulness of the results of such research for policy or decision making in practice may further be limited by study designs that do not acknowledge appropriately the significance of integrating or at least mixing qualitative and quantitative information and knowledge. Finally, the acceptance of study results - particularly when containing some kind of assessments - is often endangered by insufficient and / or late involvement of stakeholders and users. The above mentioned limitations have often been brought up in the recent past. However, despite that a certain consensus could be achieved in the last years recognising the need to tackle these issues, little progress has been made in terms of implementation within the context of (research) studies. This paper elaborates in detail on reasons that hamper the application of - interdisciplinary (i.e. natural and social science), - trans-disciplinary (i.e. co-production of knowledge) and - integrative (i.e. combining qualitative and quantitative approaches) work. It is based on the experience gained through a number of applied climate change vulnerability studies carried out within the context of various GIZ-financed development cooperation projects, a consultancy project for the German Environment Agency as well as the workshop series INQUIMUS, which tackles particularly the issues of mixing qualitative and quantitative research approaches.

    Translating policies about sustainable development as a social process and sustainability outcomes into the real world of social-ecological systems involves several challenges. Hence, research policies advocate improved innovative problem-solving capacity. One approach is transdisciplinary research that integrates research disciplines, as well as researchers and practitioners. Drawing upon 14 experiences of problem-solving, we used group modeling to map perceived barriers and bridges for researchers' and practitioners' joint knowledge production and learning towards transdisciplinary research. The analysis indicated that the transdisciplinary research process is influenced by (1) the amount of traditional disciplinary formal and informal control, (2) adaptation of project applications to fill the transdisciplinary research agenda, (3) stakeholder participation, and (4) functional team building/development based on self-reflection and experienced leadership. Focusing on implementation of green infrastructure policy as a common denominator for the delivery of ecosystem services and human well-being, we discuss how to diagnose social-ecological systems, and use knowledge production and collaborative learning as treatments.

    Chen Su-May Sheih

    2016-11-01

    Full Text Available Patrons of public libraries are more diverse and complex than those of other types of libraries, implying potentially more unexpected and difficult situations. Negative emotions such as frustration and anxiety are generated among librarians when they must handle problem patrons, an effort that may influence the work efficiency of librarians and their physical and mental health. This study conducted a semi-structured in-depth interview, using public service librarians in Taiwan as subjects, to explore the categories of problem patrons and their behavioral characteristics. According to the results, the behavioral characteristics of problem patrons can be divided into 6 categories: interfering with others, violating library regulations, influencing library works, improperly using resources and facilities, breaking laws, and exhibiting a psychological disorder as well as violating social norms. On the basis of the research results, this study offers suggestions for future reference when public libraries must handle problem patrons.

    2012-10-01

    Full Text Available This paper presents results from a three-part study on diagnosis of children with affective and behavior disorders. We examined the reliability, discriminant, and predictive validity of common diagnoses used in mental health services research using a research diagnostic interview. Results suggest four problems: a some diagnoses demonstrate internal consistency only slightly better than symptoms chosen at random; b diagnosis did not add appreciably to a brief global functioning screen in predicting service use; c low inter-rater reliability among informants and clinicians for six of the most common diagnoses; and d clinician diagnoses differed between sites in ways that reflect different reimbursement strategies. The study concludes that clinicians and researchers should not assume diagnosis is a useful measure of child and adolescent problems and outcomes until there is more evidence supporting the validity of diagnosis.

    The quest for an active and healthy ageing can be considered a "wicked problem." It is a social and cultural problem, which is difficult to solve because of incomplete, changing, and contradictory requirements. These problems are tough to manage because of their social complexity. They are a group of linked problems embedded in the structure of the communities in which they occur. First, they require the knowledge of the social and cultural context in which they occur. They can be solved only by understanding of what people do and why they do it. Second, they require a multidisciplinary approach. Wicked problems can have different solutions, so it is critical to capture the full range of possibilities and interpretations. Thus, we suggest that Università Cattolica del Sacro Cuore (UCSC) is well suited for accepting and managing this challenge because of its applied research orientation, multidisciplinary approach, and integrated vision. After presenting the research activity of UCSC, we describe a possible "systems thinking" strategy to consider the complexity and interdependence of active ageing and healthy living.

    Crigger, N J; Holcomb, L; Weiss, J

    2001-09-01

    A growing number of nurse researchers travel globally to conduct research in poor and underserved populations in developing nations. These researchers, while well versed in research ethics, often find it difficult to apply traditional ethical standards to populations in developing countries. The problem of applying ethical standards across cultures is explained by a long-standing debate about the nature of ethical principles. Fundamentalism is the philosophical stance that ethical principles are universal, while the anthropologically-based 'multicultural' model claims the philosophical position that principles are culturally bound. The authors explicate the two philosophical stances and advocate a morally sensitive but moderate position of 'ethical multiculturalism' rather than favouring either of the above philosophical positions. The final section suggests ways to promote ethical multiculturalism while planning and conducting nursing research.

    Energy Technology Data Exchange (ETDEWEB)

    1994-06-01

    Air pollution in Mexico City has increased along with the growth of the city, the movement of its population, and the growth of employment created by industry. The main cause of pollution in the city is energy consumption. Therefore, it is necessary to take into account the city`s economic development and its prospects when considering the technological relationships between well-being and energy consumption. Air pollution in the city from dust and other particles suspended in the air is an old problem. However, pollution as we know it today began about 50 years ago with the growth of industry, transportation, and population. The level of well-being attained in Mexico City implies a high energy use that necessarily affects the valley`s natural air quality. However, the pollution has grown so fast that the City must act urgently on three fronts: first, following a comprehensive strategy, transform the economic foundation of the city with nonpolluting activities to replace the old industries, second, halt pollution growth through the development of better technologies; and third, use better fuels, emission controls, and protection of wooded areas.

    2001-06-01

    Discusses the increased public attention on violence-related problems among youth and the concomitant increased diversity in research. Youth violence involvement is a complex construct that includes violence experienced in multiple settings (home, school, neighborhood) and in multiple forms (as victims, witnesses, perpetrators, and through family members, friends, and the media). Potential impacts of such violence involvement are considerable, including increased internalizing and externalizing behaviors among youth and future problems in school adjustment and life-course development. This introductory article reviews key dimensions of youth-related violence, describes an American Psychological Association Task Force (Division 12) developed to advance relevant research, and presents examples of national resources and efforts that attempt to address this critical public health issue.

    Chen, Hongwei

    2010-01-01

    Excursions in Classical Analysis introduces undergraduate students to advanced problem solving and undergraduate research in two ways. Firstly, it provides a colourful tour of classical analysis which places a wide variety of problems in their historical context. Secondly, it helps students gain an understanding of mathematical discovery and proof. In demonstrating a variety of possible solutions to the same sample exercise, the reader will come to see how the connections between apparently inapplicable areas of mathematics can be exploited in problem-solving. This book will serve as excellent preparation for participation in mathematics competitions, as a valuable resource for undergraduate mathematics reading courses and seminars and as a supplement text in a course on analysis. It can also be used in independent study, since the chapters are free-standing.

  6. Addressing Environmental Health Inequalities

    2016-01-01

    Environmental health inequalities refer to health hazards disproportionately or unfairly distributed among the most vulnerable social groups, which are generally the most discriminated, poor populations and minorities affected by environmental risks. Although it has been known for a long time that health and disease are socially determined, only recently has this idea been incorporated into the conceptual and practical framework for the formulation of policies and strategies regarding health. In this Special Issue of the International Journal of Environmental Research and Public Health (IJERPH), “Addressing Environmental Health Inequalities—Proceedings from the ISEE Conference 2015”, we incorporate nine papers that were presented at the 27th Conference of the International Society for Environmental Epidemiology (ISEE), held in Sao Paulo, Brazil, in 2015. This small collection of articles provides a brief overview of the different aspects of this topic. Addressing environmental health inequalities is important for the transformation of our reality and for changing the actual development model towards more just, democratic, and sustainable societies driven by another form of relationship between nature, economy, science, and politics.

  7. Problems with change in R2 as applied to theory of reasoned action research.

    Science.gov (United States)

    Trafimow, David

    2004-12-01

    The paradigm of choice for theory of reasoned action research seems to depend largely on the notion of change in variance accounted for (DeltaR2) as new independent variables are added to a multiple regression equation. If adding a particular independent variable of interest increases the variance in the dependent variable that can be accounted for by the list of independent variables, then the research is deemed to be 'successful', and the researcher is considered to have made a convincing argument about the importance of the new variable. In contrast to this trend, I present arguments that suggest serious problems with the paradigm, and conclude that studies on attitude-behaviour relations would advance the field of psychology to a far greater extent if researchers abandoned it.

  8. Interventions for comorbid problem gambling and psychiatric disorders: Advancing a developing field of research.

    2016-07-01

    Despite significant psychiatric comorbidity in problem gambling, there is little evidence on which to base treatment recommendations for subpopulations of problem gamblers with comorbid psychiatric disorders. This mini-review draws on two separate systematic searches to identify possible interventions for comorbid problem gambling and psychiatric disorders, highlight the gaps in the currently available evidence base, and stimulate further research in this area. In this mini-review, only 21 studies that have conducted post-hoc analyses to explore the influence of psychiatric disorders or problem gambling subtypes on gambling outcomes from different types of treatment were identified. The findings of these studies suggest that most gambling treatments are not contraindicated by psychiatric disorders. Moreover, only 6 randomized studies comparing the efficacy of interventions targeted towards specific comorbidity subgroups with a control/comparison group were identified. The results of these studies provide preliminary evidence for modified dialectical behavior therapy for comorbid substance use, the addition of naltrexone to cognitive-behavioral therapy (CBT) for comorbid alcohol use problems, and the addition of N-acetylcysteine to tobacco support programs and imaginal desensitisation/motivational interviewing for comorbid nicotine dependence. They also suggest that lithium for comorbid bipolar disorder, escitalopram for comorbid anxiety disorders, and the addition of CBT to standard drug treatment for comorbid schizophrenia may be effective. Future research evaluating interventions sequenced according to disorder severity or the functional relationship between the gambling behavior and comorbid symptomatology, identifying psychiatric disorders as moderators of the efficacy of problem gambling interventions, and evaluating interventions matched to client comorbidity could advance this immature field of study.

This paper aims to review recent research on adult gambling and problem gambling (since 2000) and then, in the context of a growing liberalization of the gambling market in the European Union, intends to provide a more detailed analysis of adult gambling behavior across European countries. Methods A systematic literature search was carried out using academic databases, Internet, and governmental websites. Results Following this search and utilizing exclusion criteria, 69 studies on adult gambling prevalence were identified. These studies demonstrated that there are wide variations in past-year problem gambling rates across different countries in the world (0.12-5.8%) and in Europe (0.12-3.4%). However, it is difficult to directly compare studies due to different methodological procedures, instruments, cut-offs, and time frames. Despite the variability among instruments, some consistent results with regard to demographics were found. Discussion and conclusion The findings highlight the need for continuous monitoring of problem gambling prevalence rates in order to examine the influence of cultural context on gambling patterns, assess the effectiveness of policies on gambling-related harms, and establish priorities for future research.

    Objective The aims of the present study were to explore the beliefs of Australian experts in tobacco control and change champions working in mental health and tobacco cessation, and to identify measures for addressing the problem of high smoking rates for people with mental illness. Methods Qualitative interviews were undertaken to explore participants' views, and the Delphi technique was used to achieve consensus on ways in which the problem would be best addressed. Results This consensus centred on the need for leadership within the mental health system. The problem was reconceptualised from being solely the responsibility of the mental health sector into an issue that requires the combined resources of a partnership and shared leadership between government and non-government services, public health leaders, policy makers and people with mental illness and their families. Conclusions Collaboration would raise the priority of the issue, reduce the debilitating effect of stigma and discrimination within the mental health sector and would place smoking reduction firmly on the political and public agenda. A recovery-orientated focus would increase the skill base and be inclusive of workers, families and carers of people with mental illness who face smoking issues on a daily basis. Reconceptualising this as an issue that would benefit from cooperation and partnerships would disrupt the notion that the problem is solely the responsibility of the mental health sector. What is known about the topic? Rates of smoking have remained high for people with mental illness despite population-wide public health strategies successfully reducing smoking rates in the general population. For people with mental illness, the benefits of quitting smoking for both their mental and physical health are overshadowed by concerns about the complexity of their needs. There is a lack of knowledge about how smoking cessation support can be improved to increase success rates in smokers with

    Full Text Available Abstract Background Musculoskeletal problems such as low back pain, neck, knee and shoulder pain are leading causes of disability and activity limitation in adults and are most frequently managed within primary care. There is a clear trend towards large, high quality trials testing the effectiveness of common non-pharmacological interventions for these conditions showing, at best, small to moderate benefits. This paper summarises the main lessons learnt from recent trials of the effectiveness of non-pharmacological therapies for common musculoskeletal conditions in primary care and provides agreed research priorities for future clinical trials. Methods Consensus development using nominal group techniques through national (UK and international workshops. During a national Clinical Trials Thinktank workshop in April 2007 in the UK, a group of 30 senior researchers experienced in clinical trials for musculoskeletal conditions and 2 patient representatives debated the possible explanations for the findings of recent high quality trials of non-pharmacological interventions. Using the qualitative method of nominal group technique, these experts developed and ranked a set of priorities for future research, guided by the evidence from recent trials of treatments for common musculoskeletal problems. The recommendations from the national workshop were presented and further ranked at an international symposium (hosted in Canada in June 2007. Results 22 recommended research priorities were developed, of which 12 reached consensus as priorities for future research from the UK workshop. The 12 recommendations were reduced to 7 agreed priorities at the international symposium. These were: to increase the focus on implementation (research into practice; to develop national musculoskeletal research networks in which large trials can be sited and smaller trials supported; to use more innovative trial designs such as those based on stepped care and subgrouping for

  12. Micro-Cognitive-Processes at the Interface Research-Education-Problem Solving

    2013-02-01

    Full Text Available A first part of this paper gives a rough picture of some difficulties encountered in research, in education, and in problem solving, for integrating them to one another. One can notice a much too global characterization of cognitive processes and a lack in the characterization of semiotic aspects. A second part analyses some theoretical limits to this integration. They are mainly due to the current conception of memories unable to take into consideration the micro-cognitive-processes at work under the reorganizations of knowledge when actualized within the situation. A third part presents a way toward the integration research-education-problem solving, relying on a cognitive approach of Culioli's enunciative theory of language, and presents some of the author's data. Micro-cognitive-processes are depicted in terms of the construction of aggregates (declarative versus procedural ones, standing at different levels of internalization and externalization, and of different processes of detachment from the situation. Then several kinds of interactions allow an on-line identification of the constraints of the task. The characterization of these constraints seems basic for each of the considered areas, research, education, and problem solving.

    Presents results of a systematic review of abstracts on studies related to violence and youth in an effort to identify areas that have received little attention in the psychological literature and to present recommendations for future research. A total of 1,168 empirical articles on violence-related problems in youth were identified by a PsycINFO (American Psychological Association, 1980-1999) search. These articles were then classified in a multidimensional grid, allowing for comparisons among different types of articles. A review of abstracts from these articles indicated that most of the research activity has been descriptive (e.g., reviewing correlates or predictors of violence involvement) or assessment related (e.g., evaluating specific measures). Fewer articles examined the treatment or prevention of violence-related problems among youth. Further, the majority of studies pertained to direct exposure to violence (as a victim or perpetrator), with very few studies looking at the effects of witnessing violence, knowing individuals exposed to violence, or being exposed to violence through the media. Comparing treatment and prevention articles, we found that the least empirical attention was paid to the prevention of violence-related problems in youth, and not a single study was identified through this search that sought to examine the prevention of youth witnessing violence. Implications for future research agendas are discussed.

    If students are to successfully grapple with authentic, complex biological problems as scientists and citizens, they need practice solving such problems during their undergraduate years. Physics education researchers have investigated student problem solving for the past three decades. Although physics and biology problems differ in structure and content, the instructional purposes align closely: explaining patterns and processes in the natural world and making predictions about physical and biological systems. In this paper, we discuss how research-supported approaches developed by physics education researchers can be adopted by biologists to enhance student problem-solving skills. First, we compare the problems that biology students are typically asked to solve with authentic, complex problems. We then describe the development of research-validated physics curricula emphasizing process skills in problem solving. We show that solving authentic, complex biology problems requires many of the same skills that practicing physicists and biologists use in representing problems, seeking relationships, making predictions, and verifying or checking solutions. We assert that acquiring these skills can help biology students become competent problem solvers. Finally, we propose how biology scholars can apply lessons from physics education in their classrooms and inspire new studies in biology education research.

    Space life science and life support engineering are prominent problems in manned deep space exploration mission. Some typical problems are discussed in this paper, including long-term life support problem, physiological effect and defense of varying extraterrestrial environment. The causes of these problems are developed for these problems. To solve these problems, research on space life science and space medical-engineering should be conducted. In the aspect of space life science, the study of space gravity biology should focus on character of physiological effect in long term zero gravity, co-regulation of physiological systems, impact on stem cells in space, etc. The study of space radiation biology should focus on target effect and non-target effect of radiation, carcinogenicity of radiation, spread of radiation damage in life system, etc. The study of basic biology of space life support system should focus on theoretical basis and simulating mode of constructing the life support system, filtration and combination of species, regulation and optimization method of life support system, etc. In the aspect of space medical-engineering, the study of bio-regenerative life support technology should focus on plants cultivation technology, animal-protein production technology, waste treatment technology, etc. The study of varying gravity defense technology should focus on biological and medical measures to defend varying gravity effect, generation and evaluation of artificial gravity, etc. The study of extraterrestrial environment defense technology should focus on risk evaluation of radiation, monitoring and defending of radiation, compound prevention and removal technology of dust, etc. At last, a case of manned lunar base is analyzed, in which the effective schemes of life support system, defense of varying gravity, defense of extraterrestrial environment are advanced respectively. The points in this paper can be used as references for intensive study on key

    Among the outstanding accomplishments of the last century is man's conquest of the air. That conquest began in 1903 when the Wright brothers made the first successful flight of an airplane at Kitty Hawk, N. C. Five years later the United States Government purchased its first airplane for the use of the Army, and began the training of officers for military flying. During the years immediately preceding the outbreak of the World War the Government and a meager aircraft industry had made important progress, but the Government, practically the only customer, had purchased less than 100 airplanes. In the meantime, leading European nations, sensing acutely the potentialities of aircraft in warfare, had made greater progress and had begun laying the foundations for the new science of aeronautics. The World War gave a remarkable impetus to the development of aeronautics and emphasized the need for organized research on the fundamental problems of flight. By act of Congress approved March 3, 1915, the National Advisory Committee for Aeronautics was created and charged with the duty of supervising, directing, and conducting fundamental scientific research and experiment in aeronautics. With the farsighted support of the Congress the Committee has led the world in the development of unique aeronautical research facilities in its laboratories at Langley Field, Va. The research programs include problems initiated by the Committee and its subcommittees and also investigations requested by the Army, the Navy, and the Civil Aeronautics Authority. The results of researches conducted under one control, serve without duplication of effort, the needs of all branches of aviation, civil and military, and exert a profound influence on the progress of aeronautics by improving the performance, efficiency, and safety of aircraft. A brief description of the results of some of the committee's researches and of the equipment employed will be found in the following pages.

  20. Development of Research Infrastructure in Nevada for the Exploitation of Hyperspectral Image Data to Address Proliferation and Detection of Chemical and Biological Materials.

    2007-12-31

    This research was to exploit hyperspectral reflectance imaging technology for the detection and mapping variability (clutter) of the natural background against which gases in the atmosphere are imaged. The natural background consists of landscape surface cover composed of consolidated rocks, unconsolidated rock weathering products, soils, coatings on rock materials, vegetation, water, materials constructed by humans, and mixtures of the above. Human made gases in the atmosphere may indicate industrial processes important to detecting non-nuclear chemical and biological proliferation. Our research was to exploit the Visible and Near-Infrared (NIR) and the Short-wave Infrared (SWIR) portions of the electromagnetic spectrum to determine the properties of solid materials on the earth’s surface that could influence the detection of gases in the Long-Wave Infrared (LWIR). We used some new experimental hyperspectral imaging technologies to collect data over the Non-Proliferation Test and Evaluation Center (NPTEC) located on the Nevada Test Site (NTS). The SpecTIR HyperSpecTIR (HST) and Specim Dual hyperspectral sensors were used to understand the variability in the imaged background (clutter), that detected, measured, identified and mapped with operational commercial hyperspectral techniques. The HST sensors were determined to be more experimental than operational because of problems with radiometric and atmospheric data correction. However the SpecTIR Dual system, developed by Specim in Finland, eventually was found to provide cost-effective hyperspectral image data collection and it was possible to correct the Dual system’s data for specific areas. Batch processing of long flightlines was still complex, and if comparison to laboratory spectra was desired, the Dual system data still had to be processed using the empirical line method. This research determined that 5-meter spatial resolution was adequate for mapping natural background variations. Furthermore, this

    Knowledge translation (KT) is a growing movement in clinical and health services research, aimed to help make research more relevant and to move research into practice and policy. This paper examines the conventional model of policy change presented in KT and assesses its applicability for increasing the impact of urban health research on urban health policy. In general, KT conceptualizes research utilization in terms of the technical implementation of scientific findings, on the part of individual decision-makers who can be "targeted" for a KT intervention, in a context that is absent of political interests. However, complex urban health problems and interventions infrequently resemble this single decision, single decision-maker model posited by KT. In order to clarify the conditions under which urban health research is more likely or not to have an influence on public policy development, we propose to supplement the conventional model with three concepts drawn from the social science: policy stages, policy networks, and a discourse analysis approach for theorizing power in policy-making.

    Full Text Available In a human-altered world where biodiversity is in decline and conservation problems abound, there is a dire need to ensure that the next generation of conservation scientists have the knowledge, skills, and training to address these problems. So called “early career researchers” (ECRs in conservation science have many challenges before them and it is clear that the status quo must change to bridge the knowledge–action divide. Here we identify thirteen practical strategies that ECRs can employ to become more relevant. In this context, “relevance” refers to the ability to contribute to solving conservation problems through engagement with practitioners, policy makers, and stakeholders. Conservation and career strategies outlined in this article include the following: thinking ‘big picture’ during conservation projects; embracing various forms of knowledge; maintaining positive relationships with locals familiar with the conservation issue; accepting failure as a viable (and potentially valuable outcome; daring to be creative; embracing citizen science; incorporating interdisciplinarity; promoting and practicing pro-environmental behaviours; understanding financial aspects of conservation; forming collaboration from the onset of a project; accepting the limits of technology; ongoing and effective networking; and finally, maintaining a positive outlook by focusing on and sharing conservation success stories. These strategies move beyond the generic and highlight the importance of continuing to have an open mind throughout the entire conservation process, from establishing one’s self as an asset to embracing collaboration and interdisciplinary work, and striving to push for professional and personal connections that strengthen personal career objectives.

  4. Addressing language barriers to healthcare in India.

    Narayan, Lalit

    2013-01-01

    In spite of a growing recognition of the importance of doctor-patient communication, the issue of language barriers to healthcare has received very little attention in India. The Indian population speaks over 22 major languages with English used as the lingua franca for biomedicine. Large-scale internal migration has meant that health workers are encountering increasing instances of language discordance within clinical settings. Research done predominantly in the West has shown language discordance to significantly affect access to care, cause problems of comprehension and adherence, and decrease the satisfaction and quality of care. Addressing language barriers to healthcare in India requires a stronger political commitment to providing non-discriminatory health services, especially to vulnerable groups such as illiterate migrant workers. Research will have to address three broad areas: the ways in which language barriers affect health and healthcare, the efficacy of interventions to overcome language barriers, and the costs of language barriers and efforts to overcome them. There is a need to address such barriers in health worker education and clinical practice. Proven strategies such as hiring multilingual healthcare workers, providing language training to health providers, employing in situ translators or using telephone interpretation services will have to be evaluated for their appropriateness to the Indian context. Internet-based initiatives, the proliferation of mobile phones and recent advances in machine translation promise to contribute to the solution.

    1998-01-01

    Based upon developmental models of disruptive behavior problems, this study examined the hypothesis that the nature of a child's externalizing problems at home may be important in predicting the probability of and nature of school adjustment problems at school entry. Parent ratings were collected for a sample of 631 behaviorally disruptive children using the Child Behavior Checklist. Confirmatory factor analyses revealed differentiated ratings of oppositional, aggressive, and hyperactive/inattentive behaviors at home. Teacher and peer nominations assessed school adjustment at the end of first grade. As expected from a developmental perspective, aggressive behaviors indicated more severe dysfunction and were more likely to generalize to the school setting than were oppositional behaviors. Hyperactive/inattentive behaviors at home led to more classroom disruption than did aggressive or oppositional behaviors. Co-occurring patterns of oppositional/aggressive and hyperactive/inattentive behaviors were more common than were single-problem patterns, and were associated with broad dysfunction in the social and classroom contexts. The results were interpreted within a developmental framework, in which oppositional, aggressive, and hyperactive/inattentive behaviors may reflect distinct (as well as shared) developmental processes that have implications for the home-to-school generalization of behavior problems and subsequent school adjustment.

    This is not the usual Editor-in-Chief letter, namely one that focuses on the accomplishments of the journal—and for ERL they have been numerous this year—but a recognition of the critical time that we are now in when it comes to addressing not only global climate change, but also the dialog between science and politics. In recognition of the many 'tipping points' that we now confront—ideally some of them positive social moments—as well as the clear scientific conclusion that environmental tipping points are points of long-lasting disruption, this paper takes a different form than I might have otherwise written. While the scientific body of knowledge around global environmental change mounts, so too, do the hopeful signs that change can happen. The election of Barack Obama is unquestionably one such sign, witnessed by the exceptional interest that his story has brought not only to US politics, but also to global views of the potential of the United States, as well as to the potential role of science and investigation in addressing pressing issues. In light of these inter-related issues, reproduced here—largely due to the efforts of Paul Baer to transcribe a remarkable conversation—is a dialog not only on the science of global warming and the potential set of means to address this issue, but also on the interaction between research, science and the political process. The dialog itself is sufficiently important that I will dispense with the usual discussion of the exciting recognition that ERL has received with an ISI rating (a factor rapidly increasing), the high levels of downloads of our papers (for some articles over 5000 and counting), and the many news and scientific publications picking up ERL articles (in recent days alone Science, Environmental Science and Technology, and The Economist).

    2011-01-01

    As the basic problems in seismology, fluid, heat and energy distribution near earthquake sources during earthquake generation have been the leading subjects of concern to seismologists. Currently, more and more research shows fluid around earthquake source areas, which plays an important role in the process of earthquake preparation and generation. However, there is considerable controversy over the source of fluid in the deep crust. As for the problem of heat around earthquake source areas, different models have been proposed to explain the stress heat flow paradox. Among them, the dynamic weakening model has been thought to be the key to solving the heat flow paradox issue. After large earthquakes, energy distribution is directly related to friction heat. It is of timely and important practical significance to immediately implement deep drilling in-site surveying to gain understanding of fluid, friction heat and energy distribution during earthquake generation. The latest international progress in fluid, heat and energy distribution research has been reviewed in this paper which will bring important inspiration for the understanding of earthquake preparation and occurrence.

On the basis of analysis of ideas about psychological safety in sports and their representation in printed or verbal form the necessity of overcoming the fragmentation and lack of system is substantiated. The authors state that one and the same sports situation can constructively or destructively affect the psychological safety of direct or indirect participants of sports events. In this context, it is important to create the psycholinguistic basis of experimental research of psychological safety in sports. Great attention is paid to systematization of the content of the concept “psychological safety in sports”. The created models of words and expressions that convey ideas about this phenomenon are of particular value. In the structure of the concept the dominant meanings, expressed in the nucleus, and additional meanings, related to the periphery of the concept are distinguished.Purpose: to explore the ideas of psychological safety in sports and their representation in printed or verbal form; to determine ways of overcoming the conceptual psycholinguistic problems in the process of experimental research of psychological safety in sports; to create the model of words and expressions which are used to verbalize the concept “psychological safety in sports”.Methodology: theoretical analysis of psychological and linguistic literature, creation of the psycholinguistic basis of experimental research, modeling of the conceptual ideas of psychological safety in sports.Results: psycholinguistic basis of experimental research of psychological safety in sports, the model of content and structure of the corresponding concept.Practical implications: Pedagogical Psychology, Sports Psychology, Philology, Psycholinguistics.DOI: http://dx.doi.org/10.12731/2218-7405-2013-8-11

    Full Text Available The purpose of the researcher's study was to examine the meaning that intimate partners of female rape victims attached to their lived experiences after the rape. The conduct of qualitative research concerning non-offending partners of female rape victims, however, often involves multifaceted ethical and practical challenges, which can be managed through the use of pilot studies. The pilot study described in this report had three objectives. The first was to pretest and refine the proposed method for locating, accessing, and recruiting intimate partners of female rape victims, within the first two weeks after the rape, for participation in a six-month longitudinal study. The second objective was to identify and prevent all possible risk factors in the proposed recruitment and data collection methods that could harm the participants' safety during the main study. The third objective was to determine the feasibility of the main study, in terms of the limited financial and human resources available. The pilot phase was valuable in identifying ethical and methodological problems during the recruitment of participants and collection of data. It allowed for methodological adjustments prior to the main study and confirmed the feasibility of the overall research design. A pilot, pretesting phase is therefore seen as an essential component of a qualitative study involving a vulnerable population.

  2. Bioethicists Can and Should Contribute to Addressing Racism.

    The problems of racism and racially motivated violence in predominantly African American communities in the United States are complex, multifactorial, and historically rooted. While these problems are also deeply morally troubling, bioethicists have not contributed substantially to addressing them. Concern for justice has been one of the core commitments of bioethics. For this and other reasons, bioethicists should contribute to addressing these problems. We consider how bioethicists can offer meaningful contributions to the public discourse, research, teaching, training, policy development, and academic scholarship in response to the alarming and persistent patterns of racism and implicit biases associated with it. To make any useful contribution, bioethicists will require preparation and should expect to play a significant role through collaborative action with others.

  5. HESS Opinions "Integration of groundwater and surface water research: an interdisciplinary problem?"

    Directory of Open Access Journals (Sweden)

    2014-02-01

    Full Text Available Today there is a great consensus that water resources research needs to become more holistic, integrating perspectives of a large variety of disciplines. Groundwater and surface water (hereafter: GW and SW are typically identified as different compartments of the hydrological cycle and were traditionally often studied and managed separately. However, despite this separation, these respective fields of study are usually not considered to be different disciplines. They are often seen as different specialisations of hydrology with different focus, yet similar theory, concepts, methodology. The present article discusses how this notion may form a substantial obstacle in the further integration of GW and SW research and management. The article focusses on the regional scale (areas of approx. 103 to 106 km2, which is identified as the scale where integration is most greatly needed, but ironically the least amount of fully integrated research seems to be undertaken. The state of research on integrating GW and SW research is briefly reviewed and the most essential differences between GW hydrology (or hydrogeology, geohydrology and SW hydrology are presented. Groundwater recharge and baseflow are used as examples to illustrate different perspectives on similar phenomena that can cause severe misunderstandings and errors in the conceptualisation of integration schemes. It is also discussed that integration of GW and SW research on the regional scale necessarily must move beyond the hydrological aspects, by collaborating with social sciences and increasing the interaction between science and the society in general. The typical elements of an ideal interdisciplinary workflow are presented and their relevance with respect to integration of GW and SW is discussed. The overall conclusions are that GW hydrology and SW hydrogeology study rather different objects of interest, using different types of observation, working on different problem settings. They have

    New studies have detected a rising number of reports of diseases in marine organisms such as corals, molluscs, turtles, mammals, and echinoderms over the past three decades. Despite the increasing disease load, microbiological, molecular, and theoretical tools for managing disease in the world's oceans are under-developed. Review of the new developments in the study of these diseases identifies five major unsolved problems and priorities for future research: (1) detecting origins and reservoirs for marine diseases and tracing the flow of some new pathogens from land to sea; (2) documenting the longevity and host range of infectious stages; (3) evaluating the effect of greater taxonomic diversity of marine relative to terrestrial hosts and pathogens; (4) pinpointing the facilitating role of anthropogenic agents as incubators and conveyors of marine pathogens; (5) adapting epidemiological models to analysis of marine disease.

  7. Assessing Risks to Wildlife Populations from Multiple Stressors: Overview of the Problem and Research Needs.

    Directory of Open Access Journals (Sweden)

    Wayne R. Munns, Jr.

    2006-06-01

    Full Text Available Wildlife populations are experiencing increasing pressure from human-induced changes in the landscape. Stressors including agricultural and urban land use, introduced invasive and exotic species, nutrient enrichment, direct human disturbance, and toxic chemicals directly or indirectly influence the quality and quantity of habitat used by terrestrial and aquatic wildlife. Governmental agencies such as the U.S. Environmental Protection Agency are required to assess risks to wildlife populations, in its broadest definition, that result from exposure to these stressors, yet considerable uncertainty exists with respect to how such assessments should be conducted. This uncertainty is compounded by questions concerning the interactive effects of co-occurring stressors, appropriate spatial scales of analysis, extrapolation of response data among species and from organisms to populations, and imperfect knowledge and use of limited data sets. Further, different risk problems require varying degrees of sophistication, methodological refinement, and data quality. These issues suggest a number of research needs to improve methods for wildlife risk assessments, including continued development of population dynamics models to evaluate the effects of multiple stressors at varying spatial scales, methods for extrapolating across endpoints and species with reasonable confidence, stressor-response relations and methods for combining them in predictive and diagnostic assessments, and accessible data sets describing the ecology of terrestrial and aquatic species. Case study application of models and methods for assessing wildlife risk will help to demonstrate their strengths and limitations for solving particular risk problems.

    2001-05-01

    Full Text Available This article presents a literature review on problem solving in Physics based on the scientific articles published in periodicals of the related field of study. The articles considered for this study were published in the period between the end of the 70`s until 1999. A categorization of the publications , according to the issue investigated, the theoretical background used, the research method adopted, the results and conclusions are considered as a starting point in order to present a research profile of the field of study. Next, this profile is discussed and analyzed , pointing out the convergent aspects that characterize the field. Taking this analysis into account, the following thesis (based on Fávero`s proposal, 2000 is defended: in order to generate tools for the teaching practice of Physics through the study of problem solving, a method that substitutes the idea of knowledge transmission in the communication processes that takes place in the classroom should be developed. This method should comprise the idea of interlocution (Vion, 2000 which focuses on social interaction as a means to reveal metacognitive regulations of the subjects, pariticipants in the process, and their development of awareness in relation to a conceptual field (Vergnaud, 1990 – Physics, in this case. The analysis of these processes considers the verbal exchanges among the subjects (Bromberg & Chabrol, 1999 developed in the situation of interaction. This thesis is supported by the articulation of concepts in Psychology, including its interface with linguistics, such as conceptual field, development of awareness and acts of speech, which are reconsidered in this study.

    Hsu, Pei-Ling

    2014-03-01

    Ashraf Shady's paper provides a first-hand reflection on how a foreign teacher used cogens as culturally adaptive pedagogy to address cultural misalignments with students. In this paper, Shady drew on several cogen sessions to showcase his journey of using different forms of cogens with his students. To improve the quality of cogens, one strategy he used was to adjust the number of participants in cogens. As a result, some cogens worked and others did not. During the course of reading his paper, I was impressed by his creative and flexible use of cogens and at the same time was intrigued by the question of why some cogens work and not others. In searching for an answer, I found that Mikhail Bakhtin's dialogism, especially the concept of addressivity, provides a comprehensive framework to address this question. In this commentary, I reanalyze the cogen episodes described in Shady's paper in the light of dialogism. My analysis suggests that addressivity plays an important role in mediating the success of cogens. Cogens with high addressivity function as internally persuasive discourse that allows diverse consciousnesses to coexist and so likely affords productive dialogues. The implications of addressivity in teaching and learning are further discussed.

    2012-01-01

    Understanding Research and Development (R&D) enterprise relationships and processes at a governance level is not a simple task, but valuable decision-making insight and evaluation capabilities can be gained from their exploration through computer simulations. This paper discusses current Modeling and Simulation (M&S) methods, addressing their applicability to R&D enterprise governance. Specifically, the authors analyze advantages and disadvantages of the four methodologies used most often by M&S practitioners: System Dynamics (SO), Discrete Event Simulation (DES), Agent Based Modeling (ABM), and formal Analytic Methods (AM) for modeling systems at the governance level. Moreover, the paper describes nesting models using a multi-method approach. Guidance is provided to those seeking to employ modeling techniques in an R&D enterprise for the purposes of understanding enterprise governance. Further, an example is modeled and explored for potential insight. The paper concludes with recommendations regarding opportunities for concentration of future work in modeling and simulating R&D governance relationships and processes.

    The CRONICAS Centre of Excellence in Chronic Diseases, based at Universidad Peruana Cayetano Heredia, was created in 2009 with support from the U.S. National Heart, Lung, and Blood Institute (NHLBI). The vision of CRONICAS is to build a globally recognized center of excellence conducting quality and innovative research and generating high-impact evidence for health. The center's identity is embedded in its core values: generosity, innovation, integrity, and quality. This review has been structured to describe the development of the CRONICAS Centre, with a focus on highlighting the ongoing translational research projects and capacity-building strategies. The CRONICAS Centre of Excellence is not a risk-averse organization: it benefits from past experiences, including past mistakes, and improves upon them and thus challenges traditional research approaches. This ethos and environment are key to fostering innovation in research.

    Students who are deaf with a disability or disabilities (DWD) constitute nearly half of the population of K-12 learners who are deaf or hard of hearing. However, there is a dearth of information on theory, research, and practice related to these learners. The authors present an overview of (a) how the field of education of students who are D/deaf and hard of hearing might refer to this unique population in a way that represents the learner, not the disability; (b) the demographic data that further define these learners; (c) a theoretical framework within which to guide research and practice; (d) prevalence and frequency of the existing research; and (e) the practices and resources available to guide practitioners and the parents of students who are DWD. Questions are posed to the field on how to continue to improve the theory, research, and pedagogy used with these students.

    Full Text Available Cynthia R Collins School of Nursing, College of Social Sciences, Loyola University, New Orleans, LA, USA Abstract: Communication and decision making in the health care workplace often involve finding solutions to ill-structured problems in uncertain, dynamic environments influenced by the competing interests of multiple stakeholders. In this environment, doctoral-prepared nurses who practice as administrators, policy makers, or advanced practice practitioners are often compelled to make important decisions based upon evaluating the merit of colleagues’ proposals against some desired organizational or population outcome. Of equal importance is the nurse leader’s own capacity to construct a compelling argument or proposal that will drive the organization forward to meet the evolving needs for quality health care. Where do we learn the skills necessary to foster this kind of critical thinking in our professional communications? The author suggests that one teaching–learning approach can be found through the thoughtful application of the work of British philosopher Steven Toulmin. Toulmin defined a model for both the analysis and derivation of logical arguments or proposals that can be readily learned and applied for use in health care systems. This model posits that a substantive argument or claim can be evaluated based on the assumptions it presumes (warrants and the strength of the evidence base (backing. Several of the social science professions have adapted Toulmin’s model to generate analysis and creative solutions to complex or emergent problems. The author proposes that an application of this model be included in the pedagogy of doctoral level Philosophy of Science or Nursing Theory courses. The Toulmin process often provides the doctoral student or novice researcher with their first real learning experience in defining the scope and inherent challenges of framing a clinical issue to be the focus of their scholarly translational

    chemical sensitivity versus bioaerosols (aerosolized microbes), or the contribution of the microorganisms to the chemical sensitivities, is not yet understood. If the inhabitants of a building exhibit similar symptoms of a clearly defined disease with a nature and time of onset that can be related to building occupancy, the disease is generally referred to as ''building-related illness.'' Once the SBS has been allowed to elevate to this level, buildings are typically evacuated and the costs associated with disruption of the building occupants, identification of the source of the problem, and eventual remediation can be significant. Understanding the primary causes of IAQ problems and how controllable factors--proper HVAC system design, allocation of adequate outdoor air, proper filtration, effective humidity control, and routine maintenance--can avert the problems may help all building owners, operators, and occupants to be more productive (Arens and Baughman 1996). This paper provides a comprehensive summary of IAQ research that has been conducted in various types of facilities. However, it focuses primarily on school facilities because, for numerous reasons that will become evident, they are far more susceptible to developing IAQ problems than most other types of facilities; and the occupants, children, are more significantly affected than adults (EPA 1998).

    Woody, G E; McLellan, A T; O'Brien, C P; Luborsky, L

    1991-01-01

    Research studies indicate that addressing psychiatric comorbidity can improve treatment for selected groups of substance-abusing patients. However, the chances for implementing the necessary techniques on a large scale are compromised by the absence of professional input and guidance within programs. This is especially true in public programs, which treat some of the most disadvantaged, disturbed, and socially destructive individuals in the entire mental health system. One starting point for upgrading the level of knowledge and training of staff members who work in this large treatment system could be to develop a better and more authoritative information dissemination network. Such a system exists in medicine; physicians are expected to read appropriate journals and to guide their treatment decisions using the data contained in the journals. Standards of practice and methods for modifying current practice are within the tradition of reading new facts, studying old ones, and comparing treatment outcome under different conditions with what is actually being done. No such general system of information-gathering or -sharing exists, particularly in public treatment programs. One of the most flagrant examples of this "educational shortfall" can be found among those methadone programs that adamantly insist on prescribing no more than 30 to 35 mg/day for all patients, in spite of the overwhelming evidence that these dose levels generally are inadequate. In some cases, program directors are unaware of studies that have shown the relationship between dose and outcome. In other cases, they are aware of the studies but do not modify their practices accordingly. This example of inadequate dosing is offered as an example of one situation that could be improved by adherence to a system of authoritative and systematic information dissemination. Many issues in substance abuse treatment do not lend themselves to information dissemination as readily as that of methadone dosing

  19. A research agenda for helminth diseases of humans: the problem of helminthiases.

    Directory of Open Access Journals (Sweden)

    Sara Lustigman

    Full Text Available A disproportionate burden of helminthiases in human populations occurs in marginalised, low-income, and resource-constrained regions of the world, with over 1 billion people in developing areas of sub-Saharan Africa, Asia, and the Americas infected with one or more helminth species. The morbidity caused by such infections imposes a substantial burden of disease, contributing to a vicious circle of infection, poverty, decreased productivity, and inadequate socioeconomic development. Furthermore, helminth infection accentuates the morbidity of malaria and HIV/AIDS, and impairs vaccine efficacy. Polyparasitism is the norm in these populations, and infections tend to be persistent. Hence, there is a great need to reduce morbidity caused by helminth infections. However, major deficiencies exist in diagnostics and interventions, including vector control, drugs, and vaccines. Overcoming these deficiencies is hampered by major gaps in knowledge of helminth biology and transmission dynamics, platforms from which to help develop such tools. The Disease Reference Group on Helminths Infections (DRG4, established in 2009 by the Special Programme for Research and Training in Tropical Diseases (TDR, was given the mandate to review helminthiases research and identify research priorities and gaps. In this review, we provide an overview of the forces driving the persistence of helminthiases as a public health problem despite the many control initiatives that have been put in place; identify the main obstacles that impede progress towards their control and elimination; and discuss recent advances, opportunities, and challenges for the understanding of the biology, epidemiology, and control of these infections. The helminth infections that will be discussed include: onchocerciasis, lymphatic filariasis, soil-transmitted helminthiases, schistosomiasis, food-borne trematodiases, and taeniasis/cysticercosis.

    The Department of Energy`s Environmental Management Science Program (EMSP) serves as a catalyst for the application of scientific discoveries to the development and deployment of technologies that will lead to reduction of the costs and risks associated with cleaning up the nation`s nuclear complex. Appendix B provides details about each of the 202 research awards funded by the EMSP. This information may prove useful to researchers who are attempting to address the Department`s environmental management challenges in their work, program managers who are planning, integrating, and prioritizing Environmental Management projects, and stakeholders and regulators who are interested in the Department`s environmental challenges. The research award information is organized by the state and institution in which the lead principal investigator is located. In many cases, the lead principal investigator is one of several investigators at a number of different institutions. In these cases, the lead investigator (major collaborator) at each of the additional institutions is listed. Each research award abstract is followed by a list of high cost projects that can potentially be impacted by the research results. High cost projects are Environmental Management projects that have total costs greater than $50 million from the year 2007 and beyond, based on the March 1998 Accelerating Cleanup: Paths to Closure Draft data, and have costs or quantities of material associated with an Environmental Management problem area. High cost projects which must remain active in the year 2007 and beyond to manage high risk are also identified. Descriptions of these potentially related high cost Environmental Management projects can be found in Appendix C. Additional projects in the same problem area as a research award can be located using the Index of High Cost Environmental Management Projects by Problem Area, at the end of Appendices B and C.

    Image coding is finding increased application in teleconferencing, archiving, and remote sensing. This thesis investigates the potential of Vector Quantization (VQ), a relatively new source coding technique, for compression of monochromatic and color images. Extensions of the Vector Quantization technique to the Address Vector Quantization method have been investigated. In Vector Quantization, the image data to be encoded are first processed to yield a set of vectors. A codeword from the codebook which best matches the input image vector is then selected. Compression is achieved by replacing the image vector with the index of the code-word which produced the best match, the index is sent to the channel. Reconstruction of the image is done by using a table lookup technique, where the label is simply used as an address for a table containing the representative vectors. A code-book of representative vectors (codewords) is generated using an iterative clustering algorithm such as K-means, or the generalized Lloyd algorithm. A review of different Vector Quantization techniques are given in chapter 1. Chapter 2 gives an overview of codebook design methods including the Kohonen neural network to design codebook. During the encoding process, the correlation of the address is considered and Address Vector Quantization is developed for color image and monochrome image coding. Address VQ which includes static and dynamic processes is introduced in chapter 3. In order to overcome the problems in Hierarchical VQ, Multi-layer Address Vector Quantization is proposed in chapter 4. This approach gives the same performance as that of the normal VQ scheme but the bit rate is about 1/2 to 1/3 as that of the normal VQ method. In chapter 5, a Dynamic Finite State VQ based on a probability transition matrix to select the best subcodebook to encode the image is developed. In chapter 6, a new adaptive vector quantization scheme, suitable for color video coding, called "A Self -Organizing

  8. Role of organic soils in the world carbon cycle: problem definition and research needs

    Armentano, T.V. (ed.)

    1979-01-01

    The following goals were addressed in the workshop: review and analysis of available data on carbon in organic soils from the past century to the present; assessment of the probable flux of carbon to and from organic soils in the near future; identification of major data inadequacies which preclude reliable analysis of the principal processes influencing carbon flux in organic soils; and proposal of research initiatives which could improve understanding of organic deposits in relation to the carbon cycle within a time frame of two to four years. The major finding of the workshop is that the organic soils are important in the overall carbon budget. Histosols and gleysols, the major organic soil deposits of the world, normally sequester organic carbon fixed by plants. They may now be releasing enough carbon to account for nearly 10% of the annual rise in atmospheric content of CO/sub 2/. Current annual release of carbon from organic soils is estimated to fall within the range of 0.03 to 0.37 x 10/sup 9/ t, a release equivalent to 1.3% to 16% of the annual increase of carbon in the atmosphere. Present annual releases of carbon from the Everglades Agricultural Area in Florida and the Sacramento-San Joaquin Valley in California are estimated at 0.017 x 10/sup 9/ tons. Annual sequestering of carbon by undrained organic soils has been estimated at about 0.045 x 10/sup 9/ tons. Several strategies for peatland management are available, including creation, preservation, functional designation, and use of wetlands for agriculture and energy supply.

    Full Text Available European project management is the main filed of the article. Assuming a connection between the degree of absorption of European funds and the degree of maturity of the Romanian society in terms of project management, the article seeks to identify the negative factors on accessing and carrying out European projects. The identified problem is a low degree of absorption of European funds in Romania, and the main objective of the research is to identify the problems faced by the public institutions in the Centre Region in accessing European funds and also the causes that led to the low absorption of European funds. This article’s research is based on a preliminary analysis performed by the authors on the rate of accessing of European funds published in the article called “The current state of European funds absorption through funding programmes – measure of the Romanian performances in the project management practice”. The conclusion of this article was a low rate of absorption of European funds in Romania, a fact that reveals a poor practice of the theory on project management. This article identifies part of the causes of this situation by identifying a part of the problems that stood in the way of beneficiaries of European funds The qualitative and quantitative research methods are used in combination in the research. The investigation has however a highly quantitative character, the purpose of the qualitative research being to provide the prerequisites for achieving the quantitative research. The interview-based qualitative research enabled the researcher to get acquainted with the subjects’ problems related to the theme of investigation, the causes that have generated these problems. This preliminary investigation to the questionnaire-based research aims to provide information that would help the researcher prepare the questionnaire, so that the questions allow getting the most comprehensive information to

    Full Text Available In traditional technologies of casting moulds and core production on the basis of high-silica sands with binding agent addition, the reclamation consists mainly of a sand recovery and very seldom of a sand and bentonite recovery.Analysis of data from several countries indicates that from 600 to 1200 kg of fresh sand is used for 1 tonne of ferrous casting alloys. In Poland it is 1000 kg of sand for 1 tonne of castings [1]. Out of this amount approximately 20% of fresh sand is used for core production and the remaining amount for rebounding moulding sands. Analysis of data from 20 largest Polish foundries, performed in 2004 [2] indicates that approximately 50% of waste foundry sands is reclaimed while the rest is directed to dumping grounds. Taking into account all remaining foundries it can be estimated that approximately 250-350 000 tonnes of waste foundry sands are sent to dumping grounds annually.Important issue are costs of storage, which depend on the kind of wastes and on the ownership form of dump-sites (municipal dumpinggrounds, plant’s or own [belonging to the foundry] as well as on their relation to the costs of purchasing fresh sands. Average charges for storage of moulding sands wastes on storage yards in Europe are within the range: 12.5 to 61 Eu, which means from 85% to above 400% of purchasing costs of 1 tonne of fresh high-silica sand. The contractual price accepted for such sand in the BREF UE document [3] is 14.56 Eu. Problems of scientific and development research concerning the reclamation of used foundry sands can be systematised according to the research fields and the actual state of knowledge - based on the analysis of scientific papers.

  11. Location-routing problems

    Energy Technology Data Exchange (ETDEWEB)

    Laporte, G.

    1987-01-01

    Location-routing problems involve simultaneously locating a number of facilities among candidate sites and establishing delivery routes to a set of users in such a way that the total system cost is minimized. This paper presents a survey of such problems. It includes some applications and examples of location-routing problems, a description of the main heuristics that have been developed for such problems, and reviews of various formulations and algorithms used in solving these problems. A more detailed review is given of exact algorithms for the vehicle routing problem, three-index vehicle flow formulations, and two-index vehicle flow formulations and algorithms for symmetrical and non-symmetrical problems. It is concluded that location-routing problem research is a fast-growing area, with most developments occurring over the past few years; however, research is relatively fragmented, often addresses problems which are too specific and contains several voids which have yet to be filled. A number of promising research areas are identified. 137 refs., 3 figs.

    The main problems about research and application of two-line hybrid rice were reviewed,including the confusing nomenclature and male sterile lines classification,the unclear characteristics of photoperiod and temperature responses and the unsuitable site selection for male sterile line and hybrid rice seed production.In order to efficiently and accurately use dual-purpose genic male sterile lines,four types,including PTGMS (photo-thermo-sensitive genic male sterile rice),TGMS (thermo-sensitive genic male sterile rice),reverse PTGMS and reverse TGMS,were proposed.A new idea for explaining the mechanism of sterility in dual-purpose hybrid rice was proposed.The transition from sterile to fertile was involved in the cooperative regulation of major-effect sterile genes and photoperiod and/or temperature sensitive ones.The minor-effect genes with accumulative effect on sterility were important factors that affected the critical temperature of sterility transfer.In order to make better use of dual-purpose lines,the charecterization of responses to photoperiod and temperature of PTGMS should be made and the identification method for the characterization of photoperiod and temperature responses of PTGMS should also be put forward.The optimal ecological site for seed production could be determined according to the historical climate data and the requirements for the meteorological conditions during the different periods of seed production.

    The purpose of the present study was to test the efficacy of a modified cognitive strategy instructional intervention originally developed to improve the mathematical problem solving of middle and high school students with learning disabilities (LD). Fifth and sixth grade general education mathematics teachers and their students of varying ability (i.e., average-achieving [AA] students, low-achieving [LA] students, and students with LD) participated in the research study. Several features of the intervention were modified, including (a) explicitness of instruction, (b) emphasis on meta-cognition, (c) focus on problem-solving prerequisites, (d) extended duration of initial intervention, and (e) addition of visual supports. General education math teachers taught all instructional sessions to their inclusive classrooms. Curriculum-based measures (CBMs) of math problem solving were administered five times over the course of the year. A multilevel model (repeated measures nested within students and students nested within schools) was used to analyze student progress on CBMs. Though CBM scores in the intervention group were initially lower than that of the comparison group, intervention students improved significantly more in the first phase, with no differences in the second phase. Implications for instruction are discussed as well as directions for future research.

    In response to the 2009-2010 influenza A(H1N1)pdm09 pandemic, a mass vaccination programme with the AS03-adjuvanted influenza A(H1N1) vaccine Pandemrix was initiated in Sweden. Unexpectedly, there were a number of narcolepsy cases amongst vaccinated children and adolescents reported. In this review, we summarize the results of a joint cross-disciplinary national research effort to investigate the adverse reaction signal from the spontaneous reporting system and to better understand possible causative mechanisms. A three- to fourfold increased risk of narcolepsy in vaccinated children and adolescents was verified by epidemiological studies. Of importance, no risk increase was observed for the other neurological and autoimmune diseases studied. Genetic studies confirmed the association with the allele HLA-DQB1*06:02, which is known to be related to sporadic narcolepsy. Furthermore, a number of studies using cellular and molecular experimental models investigated possible links between influenza vaccination and narcolepsy. Serum analysis, using a peptide microarray platform, showed that individuals who received Pandemrix exhibited a different epitope reactivity pattern to neuraminidase and haemagglutinin, as compared to individuals who were infected with H1N1. Patients with narcolepsy were also found to have increased levels of interferon-gamma production in response to streptococcus-associated antigens. The chain of patient-related events and the study results emerging over time were subjected to intense nationwide media attention. The importance of transparent communication and collaboration with patient representatives to maintain public trust in vaccination programmes is also discussed in the review. Organizational challenges due to this unexpected event delayed the initiation of some of the research projects, still the main objectives of this joint, cross-disciplinary research effort were reached, and important insights were acquired for future, similar

  16. Quantitative and qualitative approaches in educational researchproblems and examples of controlled understanding through interpretive methods

    Neumann, Karl

    1987-06-01

    In the methodological discussion of recent years it has become apparent that many research problems, including problems relating to the theory of educational science, cannot be solved by using quantitative methods. The multifaceted aspects of human behaviour and all its environment-bound subtle nuances, especially the process of education or the development of identity, cannot fully be taken into account within a rigid neopositivist approach. In employing the paradigm of symbolic interactionism as a suitable model for the analysis of processes of education and formation, the research has generally to start out from complex reciprocal social interactions instead of unambigious connections of causes. In analysing several particular methodological problems, the article demonstrates some weaknesses of quantitative approaches and then shows the advantages in and the necessity for using qualitative research tools.

    2011-05-01

    Full Text Available Abstract Background Standard mean imputation for missing values in the Western Ontario and Mc Master (WOMAC Osteoarthritis Index limits the use of collected data and may lead to bias. Probability model-based imputation methods overcome such limitations but were never before applied to the WOMAC. In this study, we compare imputation results for the Expectation Maximization method (EM and the mean imputation method for WOMAC in a cohort of total hip replacement patients. Methods WOMAC data on a consecutive cohort of 2062 patients scheduled for surgery were analyzed. Rates of missing values in each of the WOMAC items from this large cohort were used to create missing patterns in the subset of patients with complete data. EM and the WOMAC's method of imputation are then applied to fill the missing values. Summary score statistics for both methods are then described through box-plot and contrasted with the complete case (CC analysis and the true score (TS. This process is repeated using a smaller sample size of 200 randomly drawn patients with higher missing rate (5 times the rates of missing values observed in the 2062 patients capped at 45%. Results Rate of missing values per item ranged from 2.9% to 14.5% and 1339 patients had complete data. Probability model-based EM imputed a score for all subjects while WOMAC's imputation method did not. Mean subscale scores were very similar for both imputation methods and were similar to the true score; however, the EM method results were more consistent with the TS after simulation. This difference became more pronounced as the number of items in a subscale increased and the sample size decreased. Conclusions The EM method provides a better alternative to the WOMAC imputation method. The EM method is more accurate and imputes data to create a complete data set. These features are very valuable for patient-reported outcomes research in which resources are limited and the WOMAC score is used in a multivariate

  6. The importance of systems thinking to address obesity.

    Science.gov (United States)

    Finegood, Diane T

    2012-01-01

    Obesity is clearly a complex problem for both the individual and for society. Complex or 'wicked' problems have common characteristics such as heterogeneity, nonlinearity, interdependence, and self-organization. As such they require solutions appropriate for complex problems, rather than a reductionist search for the causes. 'Systems thinking' provides new ways to consider how to collectively address complex societal problems like obesity, where biology interacts with social, cultural and built environmental factors in infinite permutations and combinations. The systems that give rise to the obesity epidemic function at multiple levels, and there are important interactions between these levels. At any given level, individual actors and organizations matter and system function is optimized when individual and organizational capacity to respond is well matched to the complexity of individual tasks. Providing system supports to help networks of individuals become 'communities of practice' and 'systems of influence' may also help to accelerate the pace of effective action against obesity. Research efforts need to move away from the relentless search for the specific isolated causes of obesity and focus on solutions that have been shown to work in addressing other 'wicked' problems.

    of fears from two or more agoraphobia-related situations is now required, because this is a robust means for distinguishing agoraphobia from specific phobias. Also, the criteria for agoraphobia are now extended to be consistent with criteria sets for other anxiety disorders (e.g., a clinician's judgment of the fears as being out of proportion to the actual danger in the situation, with a typical duration of 6 months or more). From the above, these changes from DSM-IV-TR to DSM-5 in anxiety disorders make our judgments faster and more efficient in clinical practice, and DSM-5 is more useful to elucidate the pathology. In this manuscript, we discuss the application and problems based on clinical and research viewpoints regarding anxiety disorders in DSM-5.

    2006-01-01

    Full Text Available Introduction. This article results from a qualitative study of 1 information behavior in community problem-solving framed as a distributed information use environment and 2 approaches used by a best-practice library to anticipate information needs associated with community problem solving. Method. Several approaches to data collection were used - focus groups, interviews, observation of community and library meetings, and analysis of supporting documents. We focused first on the information behaviour of community groups. Finding that the library supported these activities we sought to understand its approach. Analysis. Data were coded thematically for both information behaviour concepts and themes germane to problem-solving activity. A grounded theory approach was taken to capture aspects of the library staff's practice. Themes evolved from the data; supporting documentation - reports, articles and library communication - was also coded. Results. The study showed 1 how information use environment components (people, setting, problems, problem resolutions combine in this distributed information use environment to determine specific information needs and uses; and 2 how the library contributed to the viability of this distributed information use environment. Conclusion. Community problem solving, here explicated as a distributed IUE, is likely to be seen in multiple communities. The library model presented demonstrates that by reshaping its information practice within the framework of an information use environment, a library can anticipate community information needs as they are generated and where they are most relevant.

    The 'Research Agenda for General Practice/Family Medicine and Primary Health Care in Europe' summarizes the evidence relating to the core competencies and characteristics of the Wonca Europe definition of GP/FM, and its implications for general practitioners/family doctors, researchers and policy makers. The European Journal of General Practice publishes a series of articles based on this document. The previous articles presented background, objectives, and methodology, as well results on 'primary care management' and 'community orientation' and the person-related core competencies of GP/FM. This article reflects on the general practitioner's 'specific problem solving skills'. These include decision making on diagnosis and therapy of specific diseases, accounting for the properties of primary care, but also research questions related to quality management and resource use, shared decision making, or professional education and development. Clinical research covers most specific diseases, but often lacks pragmatism and primary care relevance. Quality management is a stronghold of GP/FM research. Educational interventions can be effective when well designed for a specific setting and situation. However, their message that 'usual care' by general practitioners is insufficient may be problematic. GP and their patients need more research into diagnostic reasoning with a step-wise approach to increase predictive values in a setting characterized by uncertainty and low prevalence of specific diseases. Pragmatic comparative effectiveness studies of new and established drugs or non-pharmaceutical therapy are needed. Multi-morbidity and complexity should be addressed. Studies on therapy, communication strategies and educational interventions should consider impact on health and sustainability of effects.

    An action research inquiry into a health visitor parenting programme for parents of pre-school children with behaviour problems Parent education programmes have recently been given a high profile in this country, such provision deemed necessary because of the commonality of children's behaviour problems and because of their potentially far-reaching effects on the child, the family and society. This action research study, undertaken in Scotland, aims to explore a health visitor parenting programme for parents of pre-school children with behaviour problems. Within this study, children with behaviour problems were identified as those whose parents perceived them to have such problems, the children eliciting a wide range of behaviours and to varying degrees. Critical social science is the chosen methodology, since it allows exploration of how people comprehend their social reality. Group interactions were recorded on audio-tape and themes associated with the methodology of enlightenment, empowerment and emancipation were identified. The results of the study demonstrate how a liberating, collaborative approach to parental education can empower mothers, by increasing understanding and raising self-esteem.

    Full Text Available Abstract Background Improved quality of care is a policy objective of health care systems around the world. Implementation research is the scientific study of methods to promote the systematic uptake of clinical research findings into routine clinical practice, and hence to reduce inappropriate care. It includes the study of influences on healthcare professionals' behaviour and methods to enable them to use research findings more effectively. Cluster randomized trials represent the optimal design for evaluating the effectiveness of implementation strategies. Various codes of medical ethics, such as the Nuremberg Code and the Declaration of Helsinki inform medical research, but their relevance to cluster randomised trials in implementation research is unclear. This paper discusses the applicability of various ethical codes to obtaining consent in cluster trials in implementation research. Discussion The appropriate application of biomedical codes to implementation research is not obvious. Discussion of the nature and practice of informed consent in implementation research cluster trials must consider the levels at which consent can be sought, and for what purpose it can be sought. The level at which an intervention is delivered can render the idea of patient level consent meaningless. Careful consideration of the ownership of information, and rights of access to and exploitation of data is required. For health care professionals and organizations, there is a balance between clinical freedom and responsibility to participate in research. Summary While ethical justification for clinical trials relies heavily on individual consent, for implementation research aspects of distributive justice, economics, and political philosophy underlie the debate. Societies may need to trade off decisions on the choice between individualized consent and valid implementation research. We suggest that social sciences codes could usefully inform the consideration of

The data collection tools were the Problem Solving Inventory and Personal Information Form that were formed by Heppner & Peterson (1982 and adapted into Turkish by Şahin, Şahin & Heppner (1993. In the data analysis, descriptive statics, anova, t test and Tukey test have been utilized. In the line with the findings, it has been determined that the difference between the total mean values (85.55+20.45 that the orienteering athletes got from the problem solving inventory and their age, marital status, sports age, the years of practice in orienteering sports, and the status of being national player is significant (p<0.05. It has been found that male orienteering athletes perform higher evaluating approach compared to the female athletes, and that as the age levels increase, the problem solving skill is affected more positively. Furthermore, it has been determined that the perceptions of the participants that have more experience and sports age in orienteering sports and that do orienteering sports at a national level are more positive in the matter of problem solving skills.

    2015-07-01

    The varied, abrupt and amazing geography of the land of Peru is home of one of the major concentrations of indigenous peoples in the world. The asymmetry of power, however, in their relationship with the rest of society and the State is still very evident in their social exclusion, their gap in social and economic development, barriers in their access to health services as well as their marginalization and exploitation as subjects of health research. In this paper, we analyse two cases of research on indigenous populations in Peru, discuss them from the point of view of bioethics and reflect on important issues for researchers, research participants and the society, such as the need to respect different cultures, the need that the research being done is relevant to the needs of the population in which it is conducted and the necessity to empower indigenous communities in participatory research, to strengthen the institutions and to protect human rights, namely through ethics committees for research and the free, informed and meaningful informed consent. This approach should foster quality research, while at the same time fully respecting human rights and bioethics. We cannot forget that advancements in genetics, throughout the world, are very much in debt to indigenous populations.

    A series of seminal technological revolutions has led to a new generation of electronic devices miniaturized to such tiny scales where the strange laws of quantum physics come into play. There is no doubt that, unlike scientists and engineers of the past, technology leaders of the future will have to rely on quantum mechanics in their everyday work. This makes teaching and learning the subject of paramount importance for further progress. Mastering quantum physics is a very non-trivial task and its deep understanding can only be achieved through working out real-life problems and examples. It is notoriously difficult to come up with new quantum-mechanical problems that would be solvable with a pencil and paper, and within a finite amount of time. This book remarkably presents some 700+ original problems in quantum mechanics together with detailed solutions covering nearly 1000 pages on all aspects of quantum science. The material is largely new to the English-speaking audience. The problems have been collect...

    The radioactive management in radioactive installations must be planned and controlled. However, in the case of research laboratories, that management is compromised due to the common use of materials and installations, the lack of trained personnel and the nonexistence of clear and objective orientations by the regulator organism. Such failures cause an increasing of generated radioactive wastes and the imprecision or nonexistence of record of radioactive substances, occasioning a financial wastage, and the cancelling of licences for use of radioactive substances. This paper discusses and proposes solutions for the problems found at radioactive waste management in research laboratories

    2016-01-01

    Much effort (and money) has been invested in recent years to ensure that academic and research sites are well interconnected with high-capacity networks that, in most cases, span national and continental boundaries. However, these dedicated research and education networks, whether national (NRENs) or trans-continental (RENs), frequently have Acceptable Use Policies (AUPs) that restrict their use by commercial entities, notably Cloud Service Providers (CSPs). After a brief summary of the issues involved, we describe three approaches to removing the network connectivity barrier that threatens to limit the ability of academic and research institutions to profit effectively from services offered by CSPs.

  2. Research on cultural algorithm for solving routing problem of mobile agent

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    The key idea behind cultural algorithm is to explicitly acquire problem-solving knowledge from the evolving population and in return apply that knowledge to guide the search. In this article, cultural algorithm-simulated annealing is proposed to solve the routing problem of mobile agent. The optimal individual is accepted to improve the belief space's evolution of cultural algorithms by simulated annealing. The step size in search is used as situational knowledge to guide the search of optimal solution in the population space. Because of this feature, the search time is reduced. Experimental results show that the algorithm proposed in this article can ensure the quality of optimal solutions, and also has better convergence speed. The operation efficiency of the system is considerably improved.

    2008-01-01

    We usually describle a comparatively more complex control system, especially a multi-inputs and multioutputs system by time domation analytical procedure. While the system's controllability means whether the system is controllable according to certain requirements. It involves not only the system's outputs' controllability but also the controllability of the system's partial or total conditions. The movement is described by difference equation in the linear discrete-time system. Therefore, the problem of controllability of the linear discrete-time system has been converted into a problem of the controllability of discrete-time difference equation. The thesis makes out the determination method of the discrete-time system's controllability and puts forward the sufficient and necessary conditions to determine it's controllability by making a study on the controllability of the linear discrete-time equation.

    2015-04-01

    Full Text Available Since 2013, the authors’ Japanese team in the Department of Science Education at Shizuoka University has held trials of STEM Education in informal fields as participatory action research (e.g., Science museum in Shizuoka, Lifelong Learning Center in Fujieda City, and STEM Summer camp for the preparation for implementing STEM education in public schools and for proposing science education reform in a Japanese context. Problems in preparing STEM lessons include numerous new instructional materials and programs and emerging specialized schools. In addition, while most of these initiatives address one or more of the STEM subjects separately, there are increasing calls for emphasizing connections between and among the subjects (Honey, Pearson and Schweingruber, 2014. Unfamiliar problems for Japanese teachers are, What is Engineering? What is Design? and How can they be implemented in lessons? While gathering STEM learning materials to implement in their STEM Summer Camp, the authors noticed a pattern with which to develop a STEM lesson and developed a template “T-SM-E” in reference to prior STEM studies. After the STEM Summer Camp, the authors introduced the model in the pre-service teacher preparation program. As a result, the authors received suggestions about how teachers can develop integrated STEM lessons, how undergraduate (UG teachers can implement it in their lessons, and how teachers can assess student learning in their STEM lessons. From standard based student assessments and reflections written by the UG teachers, the authors found that it was difficult for the UG teachers to include technology in their lessons, and their assessment also indicated that the students did not show performance proficiency in technology. The authors discuss this existing problem in the Japanese education system.

This paper assesses some of the guides for constructing questionnaire as well as it uses and the extent to which it enhanced manager’s access to reliable data and information. Descriptive method is employed for the study. Findings revealed that poor or badly prepared questionnaire produce questionnaire that does not provide effective results. Managers and researchers that use such questionnaire hardly achieve their organisational and research objectives. The need for good, well prepared and adequate questionnaire is exemplified by its being the primary tool for analytical research. The study recommends that questionnaire be properly prepared for effective research outcome.

    The Flexible Image Transport System (FITS) standard has been a great boon to astronomy, allowing observatories, scientists and the public to exchange astronomical information easily. The FITS standard is, however, showing its age. Developed in the late 1970s the FITS authors made a number of implementation choices for the format that, while common at the time, are now seen to limit its utility with modern data. The authors of the FITS standard could not appreciate the challenges which we would be facing today in astronomical computing. Difficulties we now face include, but are not limited to, having to address the need to handle an expanded range of specialized data product types (data models), being more conducive to the networked exchange and storage of data, handling very large datasets and the need to capture significantly more complex metadata and data relationships. There are members of the community today who find some (or all) of these limitations unworkable, and have decided to move ahead with storin...

    2011-07-01

    Neurological disorders are becoming increasingly common in developed countries as a result of the aging population. In spite of medications, these disorders can result in progressive loss of function as well as chronic physical, cognitive, and emotional disability that ultimately places enormous emotional and economic on the patient, caretakers, and the society in general. Neuromodulation is emerging as a therapeutic option in these patients. Neuromodulation is a field, which involves implantable devices that allow for the reversible adjustable application of electrical, chemical, or biological agents to the central or peripheral nervous system with the objective of altering its functioning with the objective of achieving a therapeutic or clinically beneficial effect. It is a rapidly evolving field that brings together many different specialties in the fields of medicine, materials science, computer science and technology, biomedical, and neural engineering as well as the surgical or interventional specialties. It has multiple current and emerging indications, and an enormous potential for growth. The main challenges before it are in the need for effective collaboration between engineers, basic scientists, and clinicians to develop innovations that address specific problems resulting in new devices and clinical applications.

    2009-08-01

    Since the publication of Plant, Hammond, and Turner (2004), which highlighted a pressing need for researchers to pay more attention to sources of error in computer-based experiments, the landscape has undoubtedly changed, but not necessarily for the better. Readily available hardware has improved in terms of raw speed; multi core processors abound; graphics cards now have hundreds of megabytes of RAM; main memory is measured in gigabytes; drive space is measured in terabytes; ever larger thin film transistor displays capable of single-digit response times, together with newer Digital Light Processing multimedia projectors, enable much greater graphic complexity; and new 64-bit operating systems, such as Microsoft Vista, are now commonplace. However, have millisecond-accurate presentation and response timing improved, and will they ever be available in commodity computers and peripherals? In the present article, we used a Black Box ToolKit to measure the variability in timing characteristics of hardware used commonly in psychological research.

  15. The Theoretical Research for the Rotor/Fuselage Unsteady Aerodynamic Interaction Problem

    Directory of Open Access Journals (Sweden)

    Liu Dawei

    2016-07-01

    Full Text Available Based on coupled unsteady panel/free-wake method, a universal analysis model was established, which provides a good prediction for the rotor/fuselage unsteady aerodynamic interaction. Considering the deficiencies of the traditional time-marching rotor free-wake algorithms, notably on stability and efficiency, the CB3D algorithm with 3rd-order accuracy is proposed. For solving the problem that part of the wake vortices may penetrate the fuselage, a “material line” rectification method with 3rd-order accuracy is proposed. An analysis for the model accuracy was then conducted to validate the accuracy of the new model, and a comparison against the available experimental data is performed. The simulated results show a good agreement with these experimental data. With the new model, several simulations are conducted for the typical rotor/fuselage aerodynamic interaction, and the results are analyzed.

    Full Text Available Judith M Jarosinski,1 Jane A Fox21Nursing Department, Henson School of Science, Salisbury University, Salisbury, MD, 2School of Nursing, College of Health and Human Services, University of North Carolina Wilmington, Wilmington, NC, USAAbstract: In this article, the authors explore the risks pregnant women experience due to mental illness and intimate partner violence (IPV and discuss the nursing role involved in the management of their care. For many women, pregnancy is a time of hopeful anticipation, yet for others, pregnancy reflects a new or an ongoing struggle with mental illness. The sequelae of untreated mental illness can be as severe as infanticide, maternal suicide, lack of maternal attachment, and inability to parent. Newborns whose mothers misuse alcohol and drugs are at risk of fetal alcohol spectrum disorders and neonatal addiction syndrome. Women who live with IPV risk their physical and mental well-being as well as the safety of their newborn. Implications for practice include the use of assessment tools early and during the treatment trajectory; otherwise, mental illness and IPV in pregnancy would go undetected/untreated. Identifying postpartum depression early is key toward providing timely care for both the mother and infant; yet, few obstetric practices use a depression assessment tool such as the Edinburgh Postnatal Depression Scale. During the initial intake assessment, the Edinburgh Postnatal Depression Scale can provide the means of early treatment through targeted assessment. Further implications include specialized services for substance-misusing pregnant women whose issues are different and separate from those of men, integration of services to address their multifaceted needs, and educating nurses to the reality of comorbidity as the norm rather than the rare occurrence, with a truly holistic approach that diminishes stigma.

    Rubinstein, Francis; Pettler, Peter

    2001-08-27

    This report describes the work performed to develop and test a new switching system and communications network that is useful for economically switching lighting circuits in existing commercial buildings. The first section of the report provides the general background of the IBECS (Integrated Building Environmental Communications System) research and development work as well as the context for the development of the new switching system. The research and development effort that went into producing the first proof-of-concept (the IBECS Addressable Power Switch or APS) and the physical prototype of that concept is detailed in the second section. In the third section of the report, we detail the refined Powerline Carrier Based IBECS Title 24 Wall Switch system that evolved from the APS prototype. The refined system provided a path for installing IBECS switching technology in existing buildings that may not be already wired for light level switching control. The final section of the report describes the performance of the IBECS Title 24 Switch system as applied to a small demonstration in two offices at LBNL's Building 90. We learned that the new Powerline Carrier control systems (A-10 technology) that have evolved from the early X-10 systems have solved most of the noise problems that dogged the successful application of X-10 technologies in commercial buildings. We found that the new A-10 powerline carrier control technology can be reliable and effective for switching lighting circuits even in electrically noisy office environments like LBNL. Thus we successfully completed the task objectives by designing, building and demonstrating a new switching system that can provide multiple levels of light which can be triggered either from specially designed wall switches or from a digital communications network. By applying commercially available powerline carrier based technologies that communicate over the in-place lighting wiring system, this type of control can be

  19. Public health approach to address maternal mortality

    2012-01-01

    Full Text Available Reducing maternal mortality is one of the major challenges to health systems worldwide, more so in developing countries that account for nearly 99% of these maternal deaths. Lack of a standard method for reporting of maternal death poses a major hurdle in making global comparisons. Currently much of the focus is on documenting the "number" of maternal deaths and delineating the "medical causes" behind these deaths. There is a need to acknowledge the social correlates of maternal deaths as well. Investigating and in-depth understanding of each maternal death can provide indications on practical ways of addressing the problem. Death of a mother has serious implications for the child as well as other family members and to prevent the same, a comprehensive approach is required. This could include providing essential maternal care, early management of complications and good quality intrapartum care through the involvement of skilled birth attendants. Ensuring the availability, affordability, and accessibility of quality maternal health services, including emergency obstetric care (EmOC would prove pivotal in reducing the maternal deaths. To increase perceived seriousness of the community regarding maternal health, a well-structured awareness campaign is needed with importance be given to avoid adolescent pregnancy as well. Initiatives like Janani Surakhsha Yojna (JSY that have the potential to improve maternal health needs to be strengthened. Quality assessments should form an essential part of all services that are directed toward improving maternal health. Further, emphasis needs to be given on research by involving multiple allied partners, with the aim to develop a prioritized, coordinated, and innovative research agenda for women′s health.

    We discuss contemporary theories in mathematics education in order to do research on research. Our strategy consists of analysing discursively and ideologically recent key publications addressing the role of theory in mathematics education research. We examine how the field fabricates its object...... of research by deploying Foucault’s notion of bio-politics - mainly to address the object “learning” - and Žižek’s ideology critique - to address the object “mathematics”. These theories, which have already been used in the field to research teaching and learning, have a great potential to contribute...... to a reflexivity of research on its discourses and effects. Furthermore, they enable us to present a clear distinction between what has been called the sociopolitical turn in mathematics education research and what we call a positioning of mathematics education (research) practices in the Political....

    1986-01-01

    The idea for organl.zl.ng an Advanced Research Workshop entirely devoted to the Earth rotation was born in 1983 when Professor Raymond Hide suggested this topic to the special NATO panel of global transport mechanism in the Geosciences. Such a specialized meeting did not take place since the GEOP research conference on the rotation of the Earth and polar motion which was held at the Ohio State University (USA) in 1973. In the last ten years, highly precise measurements of the Earth's rotation parameters and new global geophysical data have become available allowing major advance to be made in the under­ standing of the various irregularities affecting the Earth's rotation. The aim of the workshop was to bring together scientists who have made important contributions in this field during the last decade both at the observational and geophysical interpretation levels. The confe­ rence was divided into four main topics. The first session was dedicated to the definition, implementation and maintenance of the te...

  5. Formal models in animal-metacognition research: the problem of interpreting animals' behavior.

    Science.gov (United States)

    Smith, J David; Zakrzewski, Alexandria C; Church, Barbara A

    2016-10-01

    Ongoing research explores whether animals have precursors to metacognition-that is, the capacity to monitor mental states or cognitive processes. Comparative psychologists have tested apes, monkeys, rats, pigeons, and a dolphin using perceptual, memory, foraging, and information-seeking paradigms. The consensus is that some species have a functional analog to human metacognition. Recently, though, associative modelers have used formal-mathematical models hoping to describe animals' "metacognitive" performances in associative-behaviorist ways. We evaluate these attempts to reify formal models as proof of particular explanations of animal cognition. These attempts misunderstand the content and proper application of models. They embody mistakes of scientific reasoning. They blur fundamental distinctions in understanding animal cognition. They impede theoretical development. In contrast, an energetic empirical enterprise is achieving strong success in describing the psychology underlying animals' metacognitive performances. We argue that this careful empirical work is the clear path to useful theoretical development. The issues raised here about formal modeling-in the domain of animal metacognition-potentially extend to biobehavioral research more broadly.

    Full Text Available Johann Jakob Wettstein (1683-1754 worked almost all his life toward the publication of his landmark 1751-52 edition of the Greek New Testament. In recent years, a large number of previously unknown sources on and by Wettstein has come to light, scattered over libraries in Europe, that provide new insights into his life and his New Testament project. This paper explores the diversity of these sources, their genres, their connections, their state of conservation and accessibility and the like. Starting from the idea that the collection offers an excellent opportunity for mapping a single scholar’s projects and international networks over time and space, it envisages a project that brings together this wealth of material. It asks what challenges and possibilities for international digital research the collection entails and formulates the desiderata concerning the necessary digital infrastructure and collaboration across traditional scholarly boundaries.

    In the period between 1797 and 1848, German medicine was considerably influenced by philosophy. It absorbed ideas deriving from neo-Platonism and vitalism, as well as the modern philosophy of nature (Naturphilosophie), especially the ideas of Schelling. The article presents the main tendencies in the German medicine of that period: the distinct character of German medical thought as compared to the rest of Europe, the deductive character of medical theories, the grounding of medical thought in non-materialist philosophy and its close ties with the Protestant religion. The author's aim is investigate how German medicine of the period evolved away from European standards set by the model of medicine as an empirical science, based on the inductive method of research. The article presents the state of German medicine of the first half of the nineteenth century against the background of socio-cultural factors and relates German medical theory of the period to the social awareness of that time.

    Full Text Available In this article authors have analysed the questions connected with globalization of economic space and the arising problems of migration of able-bodied citizens. The need to assess the conformity of the received skills and to recognise migrants’ skills in an expanding labor markets and reducing low-skilled personnel was revealed. Authors examined the professional standards’ merits in force in the territory of Russia, and revealed their shortcomings. They have defined that questions of verification of migrants qualification depend on national peculiarities of the host country and system of preparation of professional shots. It was found out that in Europe learning results obtained by different methods are recognized after the introduction of the system of education competence approach. They studied models of different systems of training and retraining of specialists, employed in different countries, based on their personal characteristics and validation of prior learning outcomes. Authors have come to the conclusion that, taking into account the specifics of Russian companies and the differences in the education system in Russia is inappropriate to apply the existing models developed by the international community. They justify the need for the creation of information and computer support for the evaluation process of competence formation. It was expressed the view that the definition of basic competences in the construction of learning paths is need. The synthesis of elements of competence “Know” was performed as example of a description of the individual graph construction. The view was expressed, that in the learning course formation its payback must be taken into account, in this connection, the authors proposed the integrated discipline assessment criterion in a hierarchical structure. The integrated criterion unites three groups of indicators of a course: consumer value, its requirement and resource intensity.

    The main objectives of Earth Science research are many folds: to understand how does this planet operates, can we model her operation and eventually develop the capability to predict such changes. However, the underlying goals of this work are to eventually serve the humanity in providing societal benefits. This requires continuous, and detailed observations from many sources in situ, airborne and space. By and large, the space observations are the way to comprehend the global phenomena across continental boundaries and provide credible boundary conditions for the mesoscale studies. This requires a multiple sensors, look angles and measurements over the same spot in accurately solving many problems that may be related to air quality, multi hazard disasters, public health, hydrology and more. Therefore, there are many ways to address these issues and develop joint implementation, data sharing and operating strategies for the benefit of the world community. This is because for large geographical areas or regions and a diverse population, some sound observations, scientific facts and analytical models must support the decision making. This is crucial for the sustainability of vital resources of the world and at the same time to protect the inhabitants, endangered species and the ecology. Needless to say, there is no single sensor, which can answer all such questions effectively. Due to multi sensor approach, it puts a tremendous burden on any single implementing entity in terms of information, knowledge, budget, technology readiness and computational power. And, more importantly, the health of planet Earth and its ability to sustain life is not governed by a single country, but in reality, is everyone's business on this planet. Therefore, with this notion, it is becoming an impractical problem by any single organization/country to bear this colossal responsibility. So far, each developed country within their means has proceeded along satisfactorily in implementing

    Address-resolution protocol (ARP) is an important protocol of data link layers that aims to obtain the corresponding relationship between Internet Protocol (IP) and Media Access Control (MAC) addresses. Traditional ARPs (address-resolution and neighbor-discovery protocols) do not consider the existence of malicious nodes, which reveals destination addresses in the resolution process. Thus, these traditional protocols allow malicious nodes to easily carry out attacks, such as man-in-the-middle attack and denial-of-service attack. To overcome these weaknesses, we propose an anonymous-address-resolution (AS-AR) protocol. AS-AR does not publicize the destination address in the address-resolution process and hides the IP and MAC addresses of the source node. The malicious node cannot obtain the addresses of the destination and the node which initiates the address resolution; thus, it cannot attack. Analyses and experiments show that AS-AR has a higher security level than existing security methods, such as secure-neighbor discovery.

    Validating experimental results in the field of computer systems is a challenging task, mainly due to the many changes in software and hardware that computational environments go through. Determining if an experiment is reproducible entails two separate tasks: re-executing the experiment and validating the results. Existing reproducibility efforts have focused on the former, envisioning techniques and infrastructures that make it easier to re-execute an experiment. In this work we focus on the latter by analyzing the validation workflow that an experiment re-executioner goes through. We notice that validating results is done on the basis of experiment design and high-level goals, rather than exact quantitative metrics. Based on this insight, we introduce a declarative format for specifying the high-level components of an experiment as well as describing generic, testable conditions that serve as the basis for validation. We present a use case in the area of storage systems to illustrate the usefulness of this approach. We also discuss limitations and potential benefits of using this approach in other areas of experimental systems research.

  18. Research and the problems of litter and medical wastes on the UK coastline.

    Recent research has shown that recreational water and bathing beach quality are associated with injury, infection and personal well-being. Continued surveillance is essential to audit the environmental and associated health trends. In the Coastwatch UK project and since 1989, annual surveys each autumn have been undertaken during a two-week study period, into the extent of littering of the UK coastline. The Public Health Laboratory Service also collects data on the use of hepatitis B immunoglobulin. In these studies it is now possible to examine time trends. The findings are not reassuring. They help to justify present concern about the health effects of discarded litter and medical waste and fears that environmental degradation could lead to loss of income from tourism. In response, some health and local authorities have started public education programmes, supplying litter bins on or near bathing beaches, emptying them regularly and undertaking beach cleansing during the summer months. The UK government is also introducing new legislation that will require 6 mm fine mesh wire screens on all shore-based sewage outlets around the UK coastline. Continued monitoring is needed to assess the effectiveness of these interventions. The need for greater personal responsibility is particularly identified.

    The present research strategies for ageing are focussed around three areas. The first area is the demographic study of the present-day populations and those in the future. The analysis of the evolution of the metropolitan French population from 1950 to 2050 indicates that the proportion of subjects aged greater than 60 years will pass from 16% to 35%. In addition, the level of dependence of these subjects will vary considerably from one to another. The second area is the integration of epidemiological data of the pathologies related to the aged subject. Numerous epidemiological studies of the aged show that the elderly population is in better health, better informed about the diseases that affect them and also financially more secure, which allows them to take better care of themselves. The epidemiological studies of certain dementias show, for example, that if we reduce the delay to when the disease appears by five years, then we reduce the prevalence by a factor of 2. The third area relates to the important new progress in the understanding of the biological mechanisms involved in cellular ageing. The recent progress in the area of cellular biology has started to decode the complex mechanisms underlying cellular ageing. The important understanding of the phenomena of apoptose with the development of relevant biological models of the natural ageing process have anticipated future treatments and, eventually, the prophylactic treatment of specific pathologies of the elderly patient.

    Approaches to the organization and conduct of cancer research changed dramatically throughout the 20th century. Despite marked differences between the epidemiological approaches of the first half of the century and molecular techniques that gained dominance in the 1980s, prominent 20th-century researchers investigating the link between sexual activity and anogenital cancers continuously invoked the same 1842 treatise by Italian surgeon Domenico Rigoni-Stern, who is said to originate the problem of establishing a causal link between sex and cancer. In this article, I investigate 20th-century references to Rigoni-Stern as a case of a broader phenomenon: scientists situating their work through narratives of venerated ancestors, or originators. By explaining shifting versions of originator narratives in light of their authors' cultural context and research practices, we can reimagine as meaningful cultural symbols the references that previous scholars have treated as specious rhetorical maneuvers. In this case, references to Rigoni-Stern provide an interpretive anchor for American scientists to construct continuity between their work and a diverse historical legacy of cancer research.
