  8. Biosphere reserves in action: Case studies of the American experience

    Energy Technology Data Exchange (ETDEWEB)



    For nearly 20 years, biosphere reserves have offered a unique framework for building the knowledge, skills, and attitudes required for conservation and sustainable use of ecosystems. The 12 case studies in this volume chronicle many of the cooperative efforts to implement the biosphere reserve concept in the United States. Considered together, these efforts involve more than 20 types of protected areas, and the participation of all levels of government, and many private organizations, academic institutions, citizens groups, and individuals. Biosphere reserves are multi-purpose areas that are nominated by the national committee of the Man and the Biosphere Program (MAB) and designated by the United Nations Educational, Scientific and Cultural Organization (UNESCO) to serve as demonstration areas for cooperation in building harmonious relationships between human activities and the conservation of ecosystems and biological diversity. Each biosphere reserve exemplifies the characteristic ecosystems of one of the worlds biogeographical regions. It is a land or coas%arine area involving human communities as integral components and including resources managed for objectives ranging from complete protection to intensive, yet sustainable development. A biosphere reserve is envisioned as a regional ''landscape for learning'' in which monitoring, research, education, and training are encouraged to support sustainable conservation of natural and managed ecosystems. It is a framework for regional cooperation involving government decisionmakers, scientists, resource managers, private organizations and local people (i.e., the biosphere reserve ''stakeholders''). Finally, each biosphere reserve is part of a global network for sharing information and experience to help address complex problems of conservation and development. The 12 case studies presented in this report represent only a few of the possible evolutions of a biosphere reserve in

  15. Transforming Language Ideologies through Action Research: A Case Study of Bilingual Science Learning (United States)

    Yang, Eunah

    This qualitative case study explored a third grade bilingual teacher's transformative language ideologies through participating in a collaborative action research project. By merging language ideologies theory, Cultural Historical Activity Theory (CHAT), and action research, I was able to identify the analytic focus of this study. I analyzed how one teacher and I, the researcher, collaboratively reflected on classroom language practices during the video analysis meetings and focus groups. Further, I analyzed twelve videos that we coded together to see the changes in the teacher's language practices over time. My unit of analysis was the discourse practice mediated by additive language ideologies. Throughout the collaborative action research process, we both critically reflected on the classroom language use. We also developed a critical consciousness about the participatory shifts and learning of focal English Learner (EL) students. Finally, the teacher made changes to her classroom language practices. The results of this study will contribute to the literacy education research field for theoretical, methodological, and practical insights. The integration of language ideologies, CHAT, and action research can help educational practitioners, researchers, and policy makers understand the importance of transforming teachers' language ideologies in designing additive learning contexts for ELs. From a methodological perspective, the transformative language ideologies through researcher and teacher collaborated video analysis process provide a unique contribution to the language ideologies in education literature, with analytic triangulation. As a practical implication, this study suggests action research can be one of the teacher education tools to help the teachers transform language ideologies for EL education.

    Full Text Available Given the easy availability of information due to social media, it is generally recognized that language teachers need to transform themselves from being mere disseminators of information to that of innovators. Literature suggests that to do so, language teachers should make action research an indispensable part of their language teaching armory. This paper aims to encourage language teachers to take charge of their own profession by conducting action research in their respective classrooms. The paper illustrates two case studies which stress on the process which can be duplicated by teachers as well as the outcome which can be used for improvement and for sharing with peers through publication. By engaging in action research, language teachers can move beyond their conventional teaching roles to become researchers cum practitioners who are able to rise to the occasion by overcoming current language issues first hand instead of taking advice from educational researchers.

  18. A management approach that drives actions strategically: balanced scorecard in a mental health trust case study. (United States)

    Schmidt, Stefan; Bateman, Ian; Breinlinger-O'Reilly, Jochen; Smith, Peter


    Achieving excellence is a current preoccupation in U.K. public health organisations. This article aims to use a case study to explain how a mental health trust delivers excellent performance using a balanced scorecard (BSC) management approach. Reports a project to implement a BSC approach in the South West Yorkshire Mental Health NHS Trust to achieve its "excellence" objectives. The authors were participants in the project. The design of the pilot project was informed theoretically by the work of Kaplan and Norton and practically by in-house discussions on a strategy to achieve excellence. Explains the process of building a BSC strategy step-by-step. Discusses how the vision and strategies of a mental health trust can be translated into tangible measures, which are the basis for actions that are driven strategically. There are many possibilities for a BSC management approach and this case study is specific to mental health trusts in the UK, although it is believed that the case has a universally applicable modus operandi. This article will help healthcare managers to evaluate the benefits of a BSC management approach. This article explains how actions can be structured in connection with a BSC management approach.

  1. Teacher and student actions to construct biology literacy at a community college: A bounded case study (United States)

    Griesel, Patricia


    Science content area literacy, particularly literacy development in college level biology, is the focus of this study. The study investigates the actions and activities of an instructor and six students over the course of 16 weeks. The study is in response to interest in the literate practices in science classes (NSES, 1996) and to the call for contextual studies that facilitate the learning of science (Borasi & Siegel, 1999; Moje, 1996; Nist & Holschuh, 1996; Prentiss, 1998). A collaborative study between the biology teacher and the researcher, this study investigates the practices believed to be effective for the development of biology literacy. Data sources, in the qualitative bounded case study (Bogdin & Biklin, 1982; Glaser & Strauss, 1967; Miles & Huberman, 1994), include: field notes of classroom observations, in-depth interviews (Seidman, 1992), class surveys, and literate artifacts. The data were coded and analyzed using a constant comparative method (Glaser & Strauss, 1967). The six students reveal similarities and differences regarding the actions, patterns, practices and use of materials and their beliefs about effective practice in the development of biology literacy. The results indicate that a variety of actions and activities are needed to facilitate the development of biology literacy. The common themes to develop from the students' data about effective teacher actions are the following: (a) involves and engages students in inquiry learning through group projects, hands-on, and group discussions; (b) relates examples, experiences, and stories; (c) exhibits expertise; (d) encourages a relaxed classroom atmosphere; (e) facilitates and coaches students; and (f) credits creativity. Further, students report their teacher to be an expert, in terms of science knowledge and literate practices, and that her expertise contributes to their understanding of biology literacy. The teachers' data reveals three themes embedded in her classroom actions: science as

  2. Documenting changes in a middle school science classroom: An action research case study (United States)

    Steffy, Herbert Lloyd

    This action research case study of an 8th grade science classroom describes the classroom changes that resulted from the teacher's growing understanding of science reform issues and the teacher's desire to incorporate computer technology directly into a core academic subject classroom. The curriculum that was developed for 8th grade science students at a central Florida middle school was named the Science and Technology Applied Realistically to Society (STARS) Project. This study describes the creation of the STARS project and then documents the collection and analysis of student responses to the project. The study concludes that changes in the classroom can happen; changes in the classroom can be informed by student perceptions to assist the reform process; changes in the classroom can effectively incorporate computer technology into a core academic subject classroom; changes in the classroom can make the learning process enjoyable for students. While the findings of this study cannot be generalized, numerous ideas are presented that have the potential for benefiting increasing numbers of science students as professional educators incorporate these ideas into their own local instructional settings.

  5. Leadership, entrepreneurship and collective action: A case study from the Colombian Pacific Region

    Directory of Open Access Journals (Sweden)

    Iván D. Lobo


    Full Text Available Building upon case-based evidence this paper explores the role of leaders in Ecomanglar, a community-based enterprise in the Black collective territory of La Plata-Bahía Málaga in the Colombian Pacific Basin, whose purpose is to provide eco and ethno-tourism services. This purpose is inextricably bound up with the region’s biophysical and institutional characteristics, both of which make management of common-pool resources a key strategic task for Ecomanglar. We propose an analytical framework to understand the role of these leaders based on the interaction of two dimensions: institutional transfer channels and operational capacity. We further analyse the role of leaders as essential ‘brokers’ to initialise and sustain collective action, a role that brings about entrepreneurial solutions for sustainable development but also creates, or exacerbates, conflicts within the community. Our findings challenge approaches which view collective action as an emergent decentralised group-oriented outcome. The paper contributes to the literature on leadership, entrepreneurship and collective action by identifying missing links and potential points of convergence. It also sheds light on some of the challenges in promoting entrepreneurship as a means to advance sustainable development in rural communities.

  6. A Case Study Examining Change in Teacher Beliefs Through Collaborative Action Research (United States)

    Vaino, Katrin; Holbrook, Jack; Rannikmäe, Miia


    The main goal of this study was to explore the role of collaborative action research in eliciting change in teacher beliefs. The beliefs were those of five chemistry teachers in implementing a new teaching approach, geared to enhancing students' scientific and technological literacy (STL). The teacher beliefs were analysed based on Ajzen's Theory of Planned Behaviour (2005) by looking at the teacher's (a) attitude towards implementing STL modules, (b) perceived subjective norms, and (c) behavioural control regarding the new teaching approach. After an introductory year, when teachers familiarised themselves with the new approach, a collaborative action research project was initiated in the second year of the study, helping teachers to minimise or overcome initially perceived constraints when implementing STL modules in their classroom. The processes of teacher change and the course of the project were investigated by teacher interviews, teacher informal commentaries, and meeting records. The formation of positive beliefs towards a STL approach increased continuously, although its extent and character varied depending on the teacher. The close cooperation, in the format of collaborative action research and especially through teacher group reflections and perceived collegial support, did support teacher professional development including change in their beliefs towards the new teaching approach. Additionally, positive feedback gained from other teachers through running a two-day in-service course in year three helped to strengthen all five teachers' existing beliefs towards the new approach. The current research demonstrated that perceived constraints, where identified, can be meaningfully addressed by teachers, through undertaking collaborative action research.

  7. An evaluation of the mode of action framework for mutagenic carcinogens case study: Cyclophosphamide. (United States)

    McCarroll, Nancy; Keshava, Nagalakshmi; Cimino, Michael; Chu, Margaret; Dearfield, Kerry; Keshava, Channa; Kligerman, Andrew; Owen, Russell; Protzel, Alberto; Putzrath, Resha; Schoeny, Rita


    In response to the 2005 revised US Environmental Protection Agency (EPA) Cancer Guidelines, a Risk Assessment Forum's Technical Panel has devised a strategy in which genetic toxicology data combined with other information are assessed to determine whether a carcinogen operates through a mutagenic mode of action (MOA). This information is necessary for EPA to decide whether age-dependent adjustment factors (ADAFs) should be applied to the cancer risk assessment. A decision tree has been developed as a part of this approach and outlines the critical steps for analyzing a compound for carcinogenicity through a mutagenic MOA (e.g., data analysis, determination of mutagenicity in animals and in humans). Agents, showing mutagenicity in animals and humans, proceed through the Agency's framework analysis for MOAs. Cyclophosphamide (CP), an antineoplastic agent, which is carcinogenic in animals and humans and mutagenic in vitro and in vivo, was selected as a case study to illustrate how the framework analysis would be applied to prove that a carcinogen operates through a mutagenic MOA. Consistent positive results have been seen for mutagenic activity in numerous in vitro assays, in animals (mice, rats, and hamsters) and in humans. Accordingly, CP was processed through the framework analysis and key steps leading to tumor formation were identified as follows: metabolism of the parent compound to alkylating metabolites, DNA damage followed by induction of multiple adverse genetic events, cell proliferation, and bladder tumors. Genetic changes in rats (sister chromatid exchanges at 0.62 mg/kg) can commence within 30 min and in cancer patients, chromosome aberrations at 35 mg/kg are seen by 1 hr, well within the timeframe and tumorigenic dose range for early events. Supporting evidence is also found for cell proliferation, indicating that mutagenicity, associated with cytotoxicity, leads to a proliferative response, which occurs early (48 hr) in the process of tumor induction

  16. Biological mode of action of a nitrophenolates-based biostimulant: case study. (United States)

    Przybysz, Arkadiusz; Gawrońska, Helena; Gajc-Wolska, Janina


    The challenges facing modern plant production involve (i) responding to the demand for food and resources of plant origin from the world's rapidly growing population, (ii) coping with the negative impact of stressful conditions mainly due to anthropopressure, and (iii) meeting consumers' new requirements and preferences for food that is high in nutritive value, natural, and free from harmful chemical additives. Despite employing the most modern plant cultivation technologies and the progress that has been made in breeding programs, the genetically-determined crop potential is still far from being fully exploited. Consequently yield and quality are often reduced, making production less, both profitable and attractive. There is an increasing desire to reduce the chemical input in agriculture and there has been a change toward integrated plant management and sustainable, environmentally-friendly systems. Biostimulants are a category of relatively new products of diverse formulations that positively affect a plant's vital processes and whose impact is usually more evident under stressful conditions. In this paper, information is provided on the mode of action of a nitrophenolates-based biostimulant, Atonik, in model species and economically important crops grown under both field and controlled conditions in a growth chamber. The effects of Atonik on plant morphology, physiology, biochemistry (crops and model plant) and yield and yield parameters (crops) is demonstrated. Effects of other biostimulants on studied in this work processes/parameters are also presented in discussion.

Autonoma de Madrid (Spain). Inst. de Fisica Teorica; Collaboration: European Twisted Mass Collaboration


    We discuss a Lattice QCD mixed action investigation employing Wilson maximally twisted mass sea and overlap valence fermions. Using four values of the lattice spacing, we demonstrate that the overlap Dirac operator assumes a point-like locality in the continuum limit. We also show that by adopting suitable matching conditions for the sea and valence theories a consistent continuum limit for the pion decay constant and light baryon masses can be obtained. Finally, we confront results for sea-valence mixed meson masses and the valence scalar correlator with corresponding expressions of chiral perturbation theory. This allows us to extract low energy constants of mixed action chiral perturbation which characterize the strength of unitarity violations in our mixed action setup.

  2. Should we embed randomized controlled trials within action research: arguing from a case study of telemonitoring

    Directory of Open Access Journals (Sweden)

    Karen Day


    Full Text Available Abstract Background Action research (AR and randomized controlled trials (RCTs are usually considered to be theoretically and practically incompatible. However, we argue that their respective strengths and weaknesses can be complementary. We illustrate our argument from a recent study assessing the effect of telemonitoring on health-related quality of life, self-care, hospital use, costs and the experiences of patients, informal carers and health care professionals in two urban hospital services and one remote rural primary care service in New Zealand. Methods Data came from authors’ observations and field notes of discussions with three groups: the healthcare providers and healthcare consumers who participated in the research, and a group of 17 researchers and collaborators. The consumers had heart failure (Site A, urban, airways disease (Site B, urban, and diabetes (Site C, rural. The research ran from 2008 (project inception until 2012 (project close-off. Researchers came from a wide range of disciplines. Both RCT and AR methods were recognised from early in the process but often worked in parallel rather than together. In retrospect, we have mapped our observed research processes to the AR cycle characteristics (creation of communicative space, democracy and participation, iterative learning and improvement, emergence, and accommodation of different ways of knowing. Results We describe the context, conduct and outcomes of the telemonitoring trial, framing the overall process in the language of AR. Although not fully articulated at the time, AR processes made the RCT sensitive to important context, e.g. clinical processes. They resulted in substantive changes to the design and conduct of the RCT, and to interpretation and uptake of findings, e.g. a simpler technology procurement process emerged. Creating a communicative space enabled co-design between the researcher group and collaborators from the provider participant group, and a stronger

  3. Using the Benner intuitive-humanistic decision-making model in action: a case study. (United States)

    Blum, Cynthia Ann


    Nurse educators make decisions that affect students in profound ways. This decision-making process may follow an intuitive-humanistic decision-making model. The author most connected with developing the intuitive model and the distinction between theoretical knowledge and experiential knowledge in the discipline of nursing is Patricia Benner (Thompson, 1999). Educators use intuition in forming judgments regarding educational planning. The educator may not be aware of subtleties that influence the decision but rely on a 'gut' instinct as they determine the appropriate action. Utilizing six key concepts identified by Dreyfus and Dreyfus (Benner and Tanner, 1987) this process utilizes what is known to the educator from previous situations to determine a course of action appropriate for the given situation. This paper describes a method one nursing educator used and identifies outcomes that could impact the career path for the student when determining if they were safe to continue in a practice based course.

  5. From intent to action: A case study for the expansion of tiger conservation from southern India

    Directory of Open Access Journals (Sweden)

    Sanjay Gubbi


    Full Text Available To conserve a large, wide-ranging carnivore like the tiger, it is critical not only to maintain populations at key habitat sites, but also to enable the persistence of the species across much larger landscapes. To do this, it is important to establish well-linked habitat networks where sites for survival and reproduction of tigers are complemented by opportunities for dispersal and colonization. On the ground, expanding protection to areas with a potential for tiger recovery still remains the means of operationalizing the landscape approach. Yet, while the gazetting of protected areas is necessary to enable this, it is not sufficient. It is essential to benchmark and monitor the process by which establishment of protected areas must necessarily be followed by management changes that enable a recovery of tigers, their prey and their habitats. In this paper, we report a case study from the Cauvery and Malai Mahadeshwara Hills Wildlife Sanctuaries of southern India, where we document the infrastructural and institutional changes that ensued after an unprecedented expansion of protected areas in this landscape. Further, we establish ecological benchmarks of the abundance and distribution of tigers, the relative abundance of their prey, and the status of their habitats, against which the recovery of tigers in this area of vast conservation potential may be assessed over time.

  6. Debt-for-Nature Swaps in Action: Two Case Studies in Peru

    Directory of Open Access Journals (Sweden)

    Catherine Kilbane. Gockel


    Full Text Available Debt-for-nature swaps are a major source of global funding for nature conservation and have been touted as a win-win solution to the problem of how to finance conservation. This paper examines how the United States' debt-for-nature-swap program, the Tropical Forest Conservation Act, works in the field. We provide an introduction to the technical aspects of the debt-for-nature swap mechanism, then describe how the program operates on the ground, using the United States-Peru swap as an example. We focus on two case studies that are largely representative of the Tropical Forest Conservation Act's work in Peru: 1 ProNaturaleza's project in the Pacaya Samiria National Reserve, and 2 five distinct projects centered around reducing illegal logging in and around Alto Purús National Park. We explore the range of programs financed through swaps, as well as whether debt-for-nature swap projects meet their goals of strengthening civil society and increasing local capacity. We also discuss the efficacy of debt-for-nature swap monitoring, which tends to privilege fiscal evaluations of area protected over direct conservation outcomes. Although Tropical Forest Conservation Act projects may well have conservation effects, the current methods of measuring success do not reflect the types of conservation impacts of Tropical Forest Conservation Act projects.

  7. Tactics and Strategy for the SEAP - Action Plan for Sustainable Energy. The city of Alessandria as a case study

    Directory of Open Access Journals (Sweden)

    Lorenzo Savio


    Full Text Available The European Union has included, since 2007, in its Plan for Energy Efficiency, a specific action addressed to the Cities: the Covenant of Mayors. The initiative involves directly the Mayors, who, signing a document of adhesion, will commit to go beyond the EU target of CO2 reduction, implementing a SEAP: Strategic Energy Action Plan. The SEAP is an innovative planning tool, which allows the city to build an overall scenario for reducing CO2 emissions, with actions belonging to different sectors. In all the steps following the signing of the Covenant (adoption, monitoring, updating the SEAP it is crucial, for the city, to adopt an effective coordination, able to put a system not only the social actors with key roles, but also all the past experiences, the best practices, demonstration projects and everything which, in the local context, can be con- sidered strategic for a sustainable urban regeneration. In Italy, the Covenant had a considerable success, with more than 1,800 cities, the 55% of the total in Europe. The city of Alessandria can be considered an interesting case study, because the SEAP development was integrated to the European Demonstrative Project Concerto AL Piano, aimed at the regeneration of a urban district, making it sustainable from the energy consumption point of view. The research group of Politecnico di Torino supported Alessandria in all the process.

  8. Applied Demography in Action: A Case Study of “Population Identification”

    Full Text Available EnglishThis case study deals with a problem quite different than the typical one facing most applied demographers. It involves the identification of a “population”using a set of criteria established by a regulatory agency. Specifically, criteria established by the US Nuclear Regulatory Commission for purposes of Site Characterization of the High Level Nuclear Waste Repository proposed for Yucca Mountain, Nevada. Consistent with other recent studies, this one suggests that a wide range of skills may be needed in dealing with problems posed to applied demographers by clients and users in the 21st century. As such,budding applied demographers, especially those nearing completion of their graduate studies, should consider adopting a set of skills beyond traditional demography.FrenchCette étude de cas se centre sur un problème très différent des problèmestypiques qui confrontent les démographes en démographie appliquée.

  9. Social Housing Policies and Best Practice Review for Retrofit Action - Case Studies from Parma (IT) (United States)

    Gherri, Barbara; Cavagliano, Chiara; Orsi, Samuele


    The paper aims at investigating the most suitable Energy Saving Measures –ESMs– for the retrofitting of Social Housing Stock –SHS– in Europe. A global awareness has been increasing, as well as education and training among architects and building sectors employees, in order to identify tailored financing schemes and advanced integrated retrofitting solutions. Several European financed programmes have been tested so far and the results are here summarized and deeply investigated in order to increase the energy performance of social housing buildings, to improve knowledge of problems associated with the retrofitting of these households, in order to provide the most appropriate solutions to be applied. Afterward, the best practices selected have been applied to some study cases in Italy, to demonstrate that the large variety of SH programmes in Europe can seriously be used, promoting the best practises’ application. A lot of theoretical and analytical work has been carried out by many European projects in the last decade, defining different approaches according to typologies of social housing buildings, focusing on national or regional regulation, on existing typologies and building techniques, on retrofitting solutions, on energy saving strategies and other managing approaches and energy saving devices. Due to the high participation of social housing organisations –SHO– and related European financed programmes, this academic research is focused on the most effective ESMs in order to encompass a large variety of needs and related solutions, even though some of them are still on course and other ones have already been completed. This research clearly demonstrates the valuable contribution these kinds of programme have in exchanging and sharing of knowledge and experience in the field of retrofit of Social Housing building across Europe, in order to primary improve the energy performance of the existing building stock and the quality of life of their

  11. Leveraging the Zachman framework implementation using action - research methodology - a case study: aligning the enterprise architecture and the business goals (United States)

    Nogueira, Juan Manuel; Romero, David; Espadas, Javier; Molina, Arturo


    With the emergence of new enterprise models, such as technology-based enterprises, and the large quantity of information generated through technological advances, the Zachman framework continues to represent a modelling tool of great utility and value to construct an enterprise architecture (EA) that can integrate and align the IT infrastructure and business goals. Nevertheless, implementing an EA requires an important effort within an enterprise. Small technology-based enterprises and start-ups can take advantage of EAs and frameworks but, because these enterprises have limited resources to allocate for this task, an enterprise framework implementation is not feasible in most cases. This article proposes a new methodology based on action-research for the implementation of the business, system and technology models of the Zachman framework to assist and facilitate its implementation. Following the explanation of cycles of the proposed methodology, a case study is presented to illustrate the results of implementing the Zachman framework in a technology-based enterprise: PyME CREATIVA, using action-research approach.

    Raffo, Veronica; Bliss, Tony; Shotten, Marc; Sleet, David; Blanchard, Claire


    This case study of the Argentina Road Safety Project demonstrates how the application of World Bank road safety project guidelines focused on institution building can accelerate knowledge transfer, scale up investment and improve the focus on results. The case study highlights road safety as a development priority and outlines World Bank initiatives addressing the implementation of the World Report on Road Traffic Injury's recommendations and the subsequent launch of the Decade of Action for Road Safety, from 2011-2020. The case study emphasizes the vital role played by the lead agency in ensuring sustainable road safety improvements and promoting the shift to a 'Safe System' approach, which necessitated the strengthening of all elements of the road safety management system. It summarizes road safety performance and institutional initiatives in Argentina leading up to the preparation and implementation of the project. We describe the project's development objectives, financing arrangements, specific components and investment staging. Finally, we discuss its innovative features and lessons learned, and present a set of supplementary guidelines, both to assist multilateral development banks and their clients with future road safety initiatives, and to encourage better linkages between the health and transportation sectors supporting them.

  14. Using Cloud collaboration for writing assignments by students with disabilities: a case study using action research

    Directory of Open Access Journals (Sweden)

    Kjrsten Keane


    Full Text Available Though separated by geographical distance, a student with disabilities, his advisor, and his writing coach consorted in the Cloud using Google applications to achieve a writing goal. Our scenario demonstrates how emerging technologies can bridge transactional distance and “virtually” supplant face-to-face conferencing around a college writing assignment. Individual levels of technical acumen with digital technology evolved to bridge the psychological and communication space between the student and his instructors. As a result, the telecollaborators developed an efficient coaching process adaptable for all students who need assistance in revising college writing assignments at a distance. Action research frames our discussion of the Cloud collaboration and provides a scaffold for student autonomy. The advantages as well and disadvantages of Cloud collaboration are outlined with reference to the National Institute of Standards of Technology definition of Cloud Computing and the Seven Principles of Universal Course Design.

  16. A case study of the development of environmental action projects from the framework of participatory action research within two middle school classrooms (United States)

    Charmatz, Kim

    The purpose of this study was to understand student and teacher empowerment through a socially critical environmental education perspective. The main research question guiding this study was: How do participants make sense of a learning experience in which students design and carry out an environmental action project in their community? This study used participatory action research and critical theory as practical and theoretical frameworks. These frameworks were relevant as this study sought to examine social change, power, and relationships through participants' experiences. The context of this study was within one seventh and one eighth grade classroom participating in environmental projects. The study was conducted in spring 2005 with an additional follow-up data collection period during spring 2006. The school was located in a densely populated metropolitan suburb. Fifty-three students, a teacher researcher, and three science teachers participated. Data sources were written surveys, scores on Middle School Environmental Literacy Survey Instrument (MSELI), observations, interviews, and student work. This study used a mixed methodological approach. Quantitative data analysis involved dependent samples t-test scores on the MSELI before and after the completion of the projects. Qualitative data were analyzed using an inductive analysis approach. This study has implications for educators interested in democratic education. Environmental action projects provide a context for students and teachers to learn interdisciplinary content knowledge, develop personal beliefs, and learn ways to take action in their communities. This pedagogy has the potential to increase cooperation, communication, and tensions within school communities. Students' participation in the development of environmental action projects may lead to feelings of empowerment or being able to make a difference in their community, as an individual or member of a group. Future research is needed to discern

  18. Practicum without borders: a case study of intercultural and pedagogical action and reflection

    Directory of Open Access Journals (Sweden)



    Full Text Available Teacher training schemes of the present 21st century ask for a new contextualization of good educational practice under frameworks of planetary scale which serve as tools aimed at interpreting culture-bound formation tracks designed for prospective teachers. The present case shows some of the opportunities and challenges of an International Practicum jointly organized by the University of Salamanca and several u.k. educational institutions. Besides their direct confrontation with culture as a living experience of diversity, the numerous agents involved in this programme were engaged in a dialogue between different pedagogical perspectives which cross-fertilized processes of teaching collaboration, mutual inquiry and a thorough rethink of areas of common linguistic, pedagogical and cultural interest. We hold that this fruitful conversation crosses borders while it offers, per se, an educational model of cohesiveness for it places the intercultural dimension at the heart of life-long education that can shape the profile of today’s European teachers.

  20. Facilitating progress in health behaviour theory development and modification: the reasoned action approach as a case study. (United States)

    Head, Katharine J; Noar, Seth M


    This paper explores the question: what are barriers to health behaviour theory development and modification, and what potential solutions can be proposed? Using the reasoned action approach (RAA) as a case study, four areas of theory development were examined: (1) the theoretical domain of a theory; (2) tension between generalisability and utility, (3) criteria for adding/removing variables in a theory, and (4) organisational tracking of theoretical developments and formal changes to theory. Based on a discussion of these four issues, recommendations for theory development are presented, including: (1) the theoretical domain for theories such as RAA should be clarified; (2) when there is tension between generalisability and utility, utility should be given preference given the applied nature of the health behaviour field; (3) variables should be formally removed/amended/added to a theory based on their performance across multiple studies and (4) organisations and researchers with a stake in particular health areas may be best suited for tracking the literature on behaviour-specific theories and making refinements to theory, based on a consensus approach. Overall, enhancing research in this area can provide important insights for more accurately understanding health behaviours and thus producing work that leads to more effective health behaviour change interventions.

  1. Machinery safety of lathe machine using SHARP-systemic human action reliability procedure: a pilot case study in academic laboratory (United States)

    Suryoputro, M. R.; Sari, A. D.; Sugarindra, M.; Arifin, R.


    This research aimed to understand the human reliability analysis, to find the SHARP method with its functionality on case study and also emphasize the practice in Lathe machine, continued with identifying improvement that could be made to the existing safety system. SHARP comprises of 7 stages including definition, screening, breakdown, representation, impact assessment, quantification and documentation. These steps were combined and analysed using HIRA, FTA and FMEA. HIRA analysed the lathe at academic laboratory showed the level of the highest risk with a score of 9 for the activities of power transmission parts and a score of 6 for activities which shall mean the moving parts required to take action to reduce the level of risk. Hence, the highest RPN values obtained in the power transmission activities with a value of 18 in the power transmission and then the activities of moving parts is 12 and the activities of the operating point of 8. Thus, this activity has the highest risk of workplace accidents in the operation. On the academic laboratory the improvement made on the engineering control initially with a machine guarding and completed with necessary administrative controls (SOP, work permit, training and routine cleaning) and dedicated PPEs.

  2. Problems, Prescriptions and Potential in Actionable Climate Change Science - A Case Study from California Coastal Marsh Research (United States)

    MacDonald, G. M.; Ambrose, R. F.; Thorne, K.; Takekawa, J.; Brown, L. N.; Fejtek, S.; Gold, M.; Rosencranz, J.


    Frustrations regarding the provision of actionable science extend to both producers and consumers. Scientists decry the lack of application of their research in shaping policy and practices while decision makers bemoan the lack of applicability of scientific research to the specific problems at hand or its narrow focus relative to the plethora of engineering, economic and social considerations that they must also consider. Incorporating climate change adds additional complexity due to uncertainties in estimating many facets of future climate, the inherent variability of climate and the decadal scales over which significant changes will develop. Recently a set of guidelines for successful science-policy interaction was derived from the analysis of transboundary water management. These are; 1 recognizing that science is a crucial but bounded input into the decision-making processes, 2 early establishment of conditions for collaboration and shared commitment among participants, 3 understanding that science-policy interactions are enhanced through greater collaboration and social or group-learning processes, 4 accepting that the collaborative production of knowledge is essential to build legitimate decision-making processes, and 5 engaging boundary organizations and informal networks as well as formal stakeholders. Here we present as a case study research on California coastal marshes, climate change and sea-level that is being conducted by university and USGS scientists under the auspices of the Southwest Climate Science Center. We also present research needs identified by a seperate analysis of best practices for coastal marsh restoration in the face of climate change that was conducted in extensive consultation with planners and managers. The initial communication, scientific research and outreach-dissemination of the marsh scientfic study are outlined and compared to best practices needs identified by planners and the science-policy guidelines outlined above

  5. Transforming Conflict into Effective Action: A Case Study on the Effects of Anthropogenic Sound on Marine Mammals (United States)

    Lewandowski, Jill K.

    Like many wicked environmental problems of our time, marine sound and its potential effects on marine mammals is characterized by high levels of scientific uncertainty, diversified values across many stakeholder groups, political and regulatory complexities, and a continually evolving ecological and social environment. Further, the history of conflict and the relationships between major actors has rooted the issue firmly in identity conflict where prejudices lead to avoidance of working together. What results is continuing controversy, failed management decisions, litigation and an increasing frustration by all parties on why a better solution cannot be found. Ultimately, the intractability of the issue is not about the science, nor will the science ever tame the issue on its own. Rather, the issue is intractable because of the conflict between people about the most appropriate path forward. It is then imperative to understand, address, and transform this conflict in order to move off the decision carousel toward improved conservation outcomes and sustainable decisions for all. This research used an explanatory case study approach to quantitatively and qualitatively investigate the context and reasoning underlying conflict on this issue. Three methods were used in order to triangulate the data, and thus add rigor, including: (1) a document review of 230 publications: (2) exploratory interviews with 10 collaborative action experts and semi-structured interviews with 58 marine mammals and sound stakeholders; and (3) participant review of selected analyses. Data elucidate how different stakeholder groups define the problem and potential solutions, how they see their role and view the role of other stakeholders, specific experiences that increased or decrease conflict, and design preferences for a collaborative effort. These data are combined with conflict transformation principles to provide recommendations for a collaborative, transformative framework designed to

  6. Stakeholder Analysis for Sharing Agro-environment Issues Towards Concerted Action: A Case Study on Diffuse Nitrate Pollution

    Directory of Open Access Journals (Sweden)

    Marco Toderi


    Full Text Available There is increasing need for participatory approaches to support the development of sustainable farming systems, based on the active involvement of stakeholders in the definition of research objectives and priorities. This paper reports the experience of a team of agronomy researchers involved in the SLIM project (, around a case study of nitrate pollution. The agro-ecosystem analysis included biophysical processes at microcatchment scale and the stakeholders’ perceptions, interests and practices related to the nitrate issue (stakeholders analysis. The conceptual SLIM framework model supported new interactions among stakeholders, that were facilitated by researchers, using dialogical tools to enable them to use scientific data and to integrate their own knowledge on the farming system. The agro-environment policies, based on compulsory prescriptions, revealed weak assumptions and insufficient integration of scientific knowledge. The stakeholder analysis contributed to the identification of priorities both for scientific research and agro-environment policies. Researchers provided the site-specific scientific knowledge, in a way that enabled stakeholders to identify the relationships between agricultural practices, landscape values and the nitrate pollution issue and to elaborate shared strategies to develop concerted actions. New spaces for interaction between researchers and stakeholders should be created to face complex agro-environment issues at catchment scale, such as the nitrate pollution of groundwater. The implication for agronomy research is that the experiments should be designed to produce suitable results to facilitate participatory sessions and that it is worthwhile to invest in specific skills of communication science and group dynamics management within the agronomy researchers’ community, in order to integrate agronomy knowledge into high quality participatory processes.

  8. Participatory evaluation of community actions as a learning methodology for personal and community empowerment: case studies and empowerment processes

    Directory of Open Access Journals (Sweden)

    Xavier Úcar Martínez


    Full Text Available Introduction: Participatory evaluation (PE is a hybrid methodology that can be used simultaneously to investigate and act in groups and communities. It can generate new knowledge about reality, but italso allows changes in the participants and their sociocultural context. This research project, developed over three years, aims to find out whether PE processes are useful and appropriate to evaluate community actionsand to generate learning that contribute to the empowerment of people who develop them.Method: The methodological structure of the research process design Participatory Evaluation processes that are applied in three selected communities-cases, over one year. The steering groups in each caseevaluated four dimensions of Community Development Plans: context, evolution, performance and results, using different techniques and group dynamics. Throughout this process, participants identify the acquiredknowledge and this is linked to indicators of empowerment, using questionnaires, content analysis and semi-structured interviews.Results: The development PE process in the three analyzed cases confirmed that PE is a useful strategy to assess participatory community actions of a territory; to report them to the people of the community; andto make shared decisions, about initiatives in order to improve community actions. The obtained results also verify that, throughout PE, there has been learning in the participants.Conclusions: The involvement of community members in the evaluation makes it more useful, fairer and more valid, but also a fourth positive consequence of PE is empowerment. From the process and the resultsof these cases of Participatory Evaluation, we consider that community EP is social transformation.

  9. Action of a 904-nm diode laser in orthopedics and traumatology: a clinical study on 447 cases (United States)

    Tam, Giuseppe


    Objective: The evidence in medical literature is that a beneficial analgesic effect can only be obtained by employing laser radiation of relatively low power density and wavelengths which are able to penetrate tissue. For this reason the semiconductor, or laser diode (GaAs, 904 nm), is the most appropriate choice in pain-reduction therapy. Summary Background Data: Low power laser (or LLL) acts on the Prostaglandins synthesis, increases the endorphins synthesis in the Rolando gelatinous substance and in the dorsal horn of the spinal cord. The L-Arginine, which is the classic substrate of nitric oxide, carries on vasodilatory and anti- inflammatory action. Methods: Treatment was carried out on 447 cases and 435 patients (250 women and 185 men) between 20th May 1987 and 31st December 1999. The patients, whose age ranged from 25 to 70, were suffering from rheumatic, degenerative and traumatic pathologies as well as cutaneous ulcers. The majority of patients had been seen by orthopaedists and rheumatologists and had undergone x-ray, ultrasound scan, etc. All patients had previously received drug-based treatment and/or physiotherapy, with poor results. Two thirds were experiencing acute symptomatic pain, while the others presented a chronic pathology with recurrent crises. We used a pulsed IR diode laser, GaAs emitting at 904 nm. Frequency of treatment: 1 application per day for 5 consecutive days, followed by a 2-day interval. The percentage reduction in symptoms or improvement in functional status were determined on the basis of objective analysis as it happens in the Legal and Insurance Medicine field. Results: Very good results were achieved especially with cases of symptomatic osteoarthritis of the cervical vertebrae, with sport-related injuries, epicondylitis, osteoarthritis of the knee, periarthritis and with cutaneous ulcers. The beneficial action of the LLLT in the latter pathology is linked to the increase in collagen and to fibroblast proliferation. The total

  10. An Ontology for Requesting Distant Robotic Action: A Case Study in Naming and Action Identification for Planning on the Mars Exploration Rover Mission (United States)

    Wales, Roxana C.; Shalin, Valerie L.; Bass, Deborah S.


    This paper focuses on the development and use of the abbreviated names as well as an emergent ontology associated with making requests for action of a distant robotic rover during the 2003-2004 NASA Mars Exploration Rover (MER) mission, run by the Jet Propulsion Laboratory. The infancy of the domain of Martian telerobotic science, in which specialists request work from a rover moving through the landscape, as well as the need to consider the interdisciplinary teams involved in the work required an empirical approach. The formulation of this ontology is grounded in human behavior and work practice. The purpose of this paper is to identify general issues for an ontology of action (specifically for requests for action), while maintaining sensitivity to the users, tools and the work system within a specific technical domain. We found that this ontology of action must take into account a dynamic environment, changing in response to the movement of the rover, changes on the rover itself, as well as be responsive to the purposeful intent of the science requestors. Analysis of MER mission events demonstrates that the work practice and even robotic tool usage changes over time. Therefore, an ontology must adapt and represent both incremental change and revolutionary change, and the ontology can never be more than a partial agreement on the conceptualizations involved. Although examined in a rather unique technical domain, the general issues pertain to the control of any complex, distributed work system as well as the archival record of its accomplishments.

  12. Differential scanning fluorometry signatures as indicators of enzyme inhibitor mode of action: case study of glutathione S-transferase.

    Directory of Open Access Journals (Sweden)

    Wendy A Lea

    Full Text Available Differential scanning fluorometry (DSF, also referred to as fluorescence thermal shift, is emerging as a convenient method to evaluate the stabilizing effect of small molecules on proteins of interest. However, its use in the mechanism of action studies has received far less attention. Herein, the ability of DSF to report on inhibitor mode of action was evaluated using glutathione S-transferase (GST as a model enzyme that utilizes two distinct substrates and is known to be subject to a range of inhibition modes. Detailed investigation of the propensity of small molecule inhibitors to protect GST from thermal denaturation revealed that compounds with different inhibition modes displayed distinct thermal shift signatures when tested in the presence or absence of the enzyme's native co-substrate glutathione (GSH. Glutathione-competitive inhibitors produced dose-dependent thermal shift trendlines that converged at high compound concentrations. Inhibitors acting via the formation of glutathione conjugates induced a very pronounced stabilizing effect toward the protein only when GSH was present. Lastly, compounds known to act as noncompetitive inhibitors exhibited parallel concentration-dependent trends. Similar effects were observed with human GST isozymes A1-1 and M1-1. The results illustrate the potential of DSF as a tool to differentiate diverse classes of inhibitors based on simple analysis of co-substrate dependency of protein stabilization.

  13. Comparison of in vivo genotoxic and carcinogenic potency to augment mode of action analysis: Case study with hexavalent chromium. (United States)

    Thompson, Chad M; Bichteler, Anne; Rager, Julia E; Suh, Mina; Proctor, Deborah M; Haws, Laurie C; Harris, Mark A


    Recent analyses-highlighted by the International Workshops on Genotoxicity Testing Working Group on Quantitative Approaches to Genetic Toxicology Risk Assessment-have identified a correlation between (log) estimates of a carcinogen's in vivo genotoxic potency and in vivo carcinogenic potency in typical laboratory animal models, even when the underlying data have not been matched for tissue, species, or strain. Such a correlation could have important implications for risk assessment, including informing the mode of action (MOA) of specific carcinogens. When in vivo genotoxic potency is weak relative to carcinogenic potency, MOAs other than genotoxicity (e.g., endocrine disruption or regenerative hyperplasia) may be operational. Herein, we review recent in vivo genotoxicity and carcinogenicity data for hexavalent chromium (Cr(VI)), following oral ingestion, in relevant tissues and species in the context of the aforementioned correlation. Potency estimates were generated using benchmark doses, or no-observable-adverse-effect-levels when data were not amenable to dose-response modeling. While the ratio between log values for carcinogenic and genotoxic potency was ≥1 for many compounds, the ratios for several Cr(VI) datasets (including in target tissue) were less than unity. In fact, the ratios for Cr(VI) clustered closely with ratios for chloroform and diethanolamine, two chemicals posited to have non-genotoxic MOAs. These findings suggest that genotoxicity may not play a major role in the cancers observed in rodents following exposure to high concentrations of Cr(VI) in drinking water-a finding consistent with recent MOA and adverse outcome pathway (AOP) analyses concerning Cr(VI). This semi-quantitative analysis, therefore, may be useful to augment traditional MOA and AOP analyses. More case examples will be needed to further explore the general applicability and validity of this approach for human health risk assessment. Copyright © 2016 The Authors. Published by

  14. Classifying chemical mode of action using gene networks and machine learning: a case study with the herbicide linuron. (United States)

    Ornostay, Anna; Cowie, Andrew M; Hindle, Matthew; Baker, Christopher J O; Martyniuk, Christopher J


    The herbicide linuron (LIN) is an endocrine disruptor with an anti-androgenic mode of action. The objectives of this study were to (1) improve knowledge of androgen and anti-androgen signaling in the teleostean ovary and to (2) assess the ability of gene networks and machine learning to classify LIN as an anti-androgen using transcriptomic data. Ovarian explants from vitellogenic fathead minnows (FHMs) were exposed to three concentrations of either 5α-dihydrotestosterone (DHT), flutamide (FLUT), or LIN for 12h. Ovaries exposed to DHT showed a significant increase in 17β-estradiol (E2) production while FLUT and LIN had no effect on E2. To improve understanding of androgen receptor signaling in the ovary, a reciprocal gene expression network was constructed for DHT and FLUT using pathway analysis and these data suggested that steroid metabolism, translation, and DNA replication are processes regulated through AR signaling in the ovary. Sub-network enrichment analysis revealed that FLUT and LIN shared more regulated gene networks in common compared to DHT. Using transcriptomic datasets from different fish species, machine learning algorithms classified LIN successfully with other anti-androgens. This study advances knowledge regarding molecular signaling cascades in the ovary that are responsive to androgens and anti-androgens and provides proof of concept that gene network analysis and machine learning can classify priority chemicals using experimental transcriptomic data collected from different fish species. © 2013.

  15. Regional health workforce planning through action research: lessons for commissioning health services from a case study in Far North Queensland. (United States)

    Panzera, Annette June; Murray, Richard; Stewart, Ruth; Mills, Jane; Beaton, Neil; Larkins, Sarah


    Creating a stable and sustainable health workforce in regional, rural and remote Australia has long been a challenge to health workforce planners, policy makers and researchers alike. Traditional health workforce planning is often reactive and assumes continuation of current patterns of healthcare utilisation. This demonstration project in Far North Queensland exemplifies how participatory regional health workforce planning processes can accurately model current and projected local workforce requirements. The recent establishment of Primary Health Networks (PHNs) with the intent to commission health services tailored to individual healthcare needs underlines the relevance of such an approach. This study used action research methodology informed by World Health Organization (WHO) systems thinking. Four cyclical stages of health workforce planning were followed: needs assessment; health service model redesign; skills-set assessment and workforce redesign; and development of a workforce and training plan. This study demonstrated that needs-based loco-regional health workforce planning can be achieved successfully through participatory processes with stakeholders. Stronger health systems and workforce training solutions were delivered by facilitating linkages and planning processes based on community need involving healthcare professionals across all disciplines and sectors. By focusing upon extending competencies and skills sets, local health professionals form a stable and sustainable local workforce. Concrete examples of initiatives generated from this process include developing a chronic disease inter-professional teaching clinic in a rural town and renal dialysis being delivered locally to an Aboriginal community. The growing trend of policy makers decentralising health funding, planning and accountability and rising health system costs increase the future utility of this approach. This type of planning can also assist the new PHNs to commission health services

  16. Optimization of active distribution networks: Design and analysis of significative case studies for enabling control actions of real infrastructure (United States)

    Moneta, Diana; Mora, Paolo; Viganò, Giacomo; Alimonti, Gianluca


    The diffusion of Distributed Generation (DG) based on Renewable Energy Sources (RES) requires new strategies to ensure reliable and economic operation of the distribution networks and to support the diffusion of DG itself. An advanced algorithm (DISCoVER - DIStribution Company VoltagE Regulator) is being developed to optimize the operation of active network by means of an advanced voltage control based on several regulations. Starting from forecasted load and generation, real on-field measurements, technical constraints and costs for each resource, the algorithm generates for each time period a set of commands for controllable resources that guarantees achievement of technical goals minimizing the overall cost. Before integrating the controller into the telecontrol system of the real networks, and in order to validate the proper behaviour of the algorithm and to identify possible critical conditions, a complete simulation phase has started. The first step is concerning the definition of a wide range of "case studies", that are the combination of network topology, technical constraints and targets, load and generation profiles and "costs" of resources that define a valid context to test the algorithm, with particular focus on battery and RES management. First results achieved from simulation activity on test networks (based on real MV grids) and actual battery characteristics are given, together with prospective performance on real case applications.

  18. A case study of participatory action research in a public new England middle school: empowerment, constraints and challenges. (United States)

    Phillips, Evelyn Newman; Berg, Marlene J; Rodriguez, Chiedza; Morgan, Damion


    PAR recognizes teachers and students as co-creators in a learning process that builds self-efficacy essential to long-term educational success. In enabling contexts, PAR projects also allow teachers to critically deconstruct societal power, examine how these dynamics are reproduced in the classroom, and work against the silencing of student voices. This case study describes the process of implementing an inquiry-based PAR model into a formal urban middle school program intended to reduce drop out rates. The anthropologist/researchers employed participant observation, interviews, and review of student work to explore the dynamics, challenges, and constraints confronted during the process. The intervention demonstrated the gap between practice and theory in a middle school environment marked by well-defined hierarchies and roles as well as high-stakes testing.

  19. Who demands collective action in an imperfect institutional environment? A case study of the profession of advocates in Russia

    Directory of Open Access Journals (Sweden)

    Anton Kazun


    Full Text Available We analyse the profession of criminal defence lawyers (“advocates” in Russia to understand their potential for collective action in an imperfect institutional environment. In 2013, we conducted a survey of 372 advocates in 9 regions of Russia. The following two main hypotheses are tested: (1 lawyers with strong ethical values have a higher demand for collective action; and (2 the negative experience of clients' rights violations by law enforcement officers can motivate advocates to support the foundation of a strong professional association. We suggest that an advocate's profession with bona fide members at the core could be an instrument to evaluate and to improve the quality of law enforcement in Russia.

  20. Neuroendocrine disruption without direct endocrine mode of action: Polychloro-biphenyls (PCBs) and bisphenol A (BPA) as case studies. (United States)

    Pinson, Anneline; Franssen, Delphine; Gérard, Arlette; Parent, Anne-Simone; Bourguignon, Jean-Pierre

    Endocrine disruption is commonly thought to be restricted to a direct endocrine mode of action i.e. the perturbation of the activation of a given type of hormonal receptor by its natural ligand. Consistent with the WHO definition of an endocrine disrupter, a key issue is the "altered function(s) of the endocrine system". Such altered functions can result from different chemical interactions, beyond agonistic or antagonistic effect at a given receptor. Based on neuroendocrine disruption by polychlorinated biphenyls and bisphenol A, this paper proposes different mechanistic paradigms that can result in adverse health effects. They are a consequence of altered endocrine function(s) secondary to chemical interaction with different steps in the physiological regulatory processes, thus accounting for a possibly indirect endocrine mode of action.

  1. Mathematical speech and practical action: a case study of the challenges of including mathematics in a school technology project (United States)

    Bungum, Berit; Manshadi, Saeed; Atle Lysne, Dag


    This paper presents a case study of how a teacher and nine-year-old students deal with mathematics in a practical technology project. By analysing videotaped dialogues between teacher and a pair of students working on constructing a house model, we identify challenges of meaningful inclusion of mathematics in the project. The dialogues are analysed in terms of an analytical framework where four categories of interaction patterns are combined with two main paradigms of mathematics teaching: the exercise paradigm and landscapes of interaction. The project in itself has a potential for facilitating landscapes of investigation in mathematics teaching. However, we find that the teacher as well as students adheres to the exercise paradigm when mathematics is involved in the activity. Two illustrating episodes from the project are examined and presented in detail in this paper. The findings illustrate that the conceptions teachers and students hold of what mathematics teaching means can act as an obstacle in attempts to realize mathematics teaching in creative and meaningful contexts for young students. We suggest that making the various purposes of a project more explicit may help overcome this obstacle, and that the mathematics involved might be taught in separate sessions in order to form a constructive part of a cross-curricular project.

  2. Geographical modelling based on spatial differentiation of fire brigade actions: A case study of Brno, Czech Republic

    Directory of Open Access Journals (Sweden)

    Popelínský Jan


    Full Text Available The paper analyzes crisis situations solved by The Fire Rescue Service of the South Moravian Region (FRS in the city of Brno during 24 weeks between 7th April 2013 and 20th September 2013. The article deals briefly with all FRS actions and then focuses on fires. The open-access database of FRS is used for analysis. It is accessed from a database of the innovative web application StreetAlert, which allows users to learn about current fire brigade actions in the specified distance from the mobile phone. The data are processed in PostgreSQL and then spatial analysis is performed using the most detailed administrative division of the city – basic settlement units. As this division of urban space is used also in the most recent Czech census (2011, it is possible to use sociodemographic statistical data for comparison. The article identifies spatial regularities in the distribution of fires, describes the structure of the fires in terms of the type of event (fires of waste, fires of grass and forest, fires of buildings, discovers their possible dependence on the specific characteristics of urban space, finds potentially dangerous places (kernel density analysis, draws valid conclusions applicable to similar settlements, and shows the possible use of the data for local government. The main benefit of the research lies in revealing the spatial distribution of the examined phenomena.

  3. The challenge of compiling data profiles to stimulate local preventive health action: a European case study from child safety. (United States)

    Alexander, Denise; Rigby, Michael; Gissler, Mika; Köhler, Lennart; MacKay, Morag


    Positive recent experience of presenting comparative child safety data at national level has instigated policy action in Europe. It was hoped a Child Safety Index could quantify how safe a community, region or locality is for its children in comparison with similar areas within Europe, as a focus for local targeted action. Validated indicators proposed by previous European projects identified from areas of child injury prevention, such as road safety, burns or poisoning, were selected to give a balanced profile, and populated from available published data. An index using a sub-score for each specific injury topic was proposed. The indicators' presentation, sensitivity and appropriateness were considered, as well as data availability. Satisfactory indicators were not identified for all areas and very few local area data were available. This forced the researchers to conclude that at present, constructing a reliable Child Safety Index for use at the local level is not feasible. There is a worrying lack of data available at the sub-national level to support injury prevention, evaluate interventions, and enable informed local decision making.

  4. The application of identified instructional strategies to science teaching in order to enhance appropriate student behavior: A collaborative action research case study (United States)

    Lamartina, Mary Fay

    For the past 2 school years, Charm City Elementary School has implemented Success For All (SFA), a whole school reform effort as a part of the literacy block. SFA follows a highly structured format for students' skill development. Over those 2 years, school administrators and teachers have noticed a tremendous reduction in the reported incidences of off task and disruptive behavior during the reading block. These observations were supported by a review of office data. During the same period, disruptive and off-task behaviors were reported with great frequency schoolwide after the literacy block. Teachers wondered why this was so. A group of grade teachers decided to investigate factors that may possibly be contributing to this obvious reduction in student misbehaviors for the purpose of reducing afternoon off task and disruptive behavior through a transfer of certain positive factors. Possible causal factors identified included the nature of the highly structured reading block, the time of day, or the materials or instructional techniques being used during SFA instruction. This was an action research case study whose purpose was to investigate and determine factors which teachers schoolwide say cause the reduction of incidents of reported misbehavior during the reading block, and to replicate the use of these positive factors during the science instructional period in order to reduce off-task actions which may lead to disruptive behavior. The findings of this study show that teachers can identify factors, which they say relate to a reduction in off task and disruptive behavior. They can identify factors which they say promote on-task and positive behaviors. Teachers can then redesign and implement these identified instructional strategies into a science curriculum that will reduce off-task and disruptive behavior. The findings discussed in this study document the value of action research in improving teacher practice. A review of the literature supports the

    Elize S. van Eeden


    Full Text Available For at least the past 180 years the Merafong Municipal region in the Gauteng Province of South Africa, (of which the Wonderfontein Catchment forms a part has strongly relied on the primary sector for its economic existence and development. In the process some human actions, also related to serious water contamination/pollution, have resulted in phases of constructions1 as well as economic and health destructions. Differences over whose environment and whose nature it is spontaneously developed, with sometimes less friendly outcomes. The ‘end result’ up to 2006 is a complicated scenario experience, similar to that of many other regions or local areas, but also very unique and somewhat frightening. The long term focus of this article is to exchange knowledge2 on the region with the objective to contribute towards creating a sustainable nvironment by ensuring closer co-operation between the various economic active cultures operating or functioning in the Merafong municipal region. In this article four aspects are covered.

  7. Insights and participatory actions driven by a socio-hydrogeological approach for groundwater management: the Grombalia Basin case study (Tunisia) (United States)

    Tringali, C.; Re, V.; Siciliano, G.; Chkir, N.; Tuci, C.; Zouari, K.


    Sustainable groundwater management strategies in water-scarce countries need to guide future decision-making processes pragmatically, by simultaneously considering local needs, environmental problems and economic development. The socio-hydrogeological approach named `Bir Al-Nas' has been tested in the Grombalia region (Cap Bon Peninsula, Tunisia), to evaluate the effectiveness of complementing hydrogeochemical and hydrogeological investigations with the social dimension of the issue at stake (which, in this case, is the identification of groundwater pollution sources). Within this approach, the social appraisal, performed through social network analysis and public engagement of water end-users, allowed hydrogeologists to get acquainted with the institutional dimension of local groundwater management, identifying issues, potential gaps (such as weak knowledge transfer among concerned stakeholders), and the key actors likely to support the implementation of the new science-based management practices resulting from the ongoing hydrogeological investigation. Results, hence, go beyond the specific relevance for the Grombaila basin, showing the effectiveness of the proposed approach and the importance of including social assessment in any given hydrogeological research aimed at supporting local development through groundwater protection measures.

    Full Text Available Severely eroded lands of southern Guam are referred to as BadLands. These are actively eroding areas of very deep, well–drained saprolite derived from tuff and tuff breccia. These badlands are exposed to overland flow, wind and rain causing sever erosion as the result of rapid runoff from the pitted, sloping sites void of vegetation. Through soil removal or sediment transport, erosion also alters the inherent physical and chemical properties of these soils. This alteration resulted in degradation, in turn affecting the environment as well as water quality in the down stream. The on-site damage from erosion is indeed a problem to environmental ecosystem of the island. Sediment lost due to erosion clogs rivers, lakes, and waterways. It reduces the water storage capacity of reservoirs and canals and increases flooding.The challenge facing soil and environmental scientists is to develop conservation and restoration strategies at the farm as well as at the watershed level that address crop production and natural resources protection needs, within a framework of increasing environmental and financial constraints. In our soil conservation program at the College of Natural and Applied Sciences of the University of Guam we have adopted integrated approaches to evaluate a variety of strategies, including the effect of conservation tillage and residue management, crop rotation with leguminous plants (sunnhemp as green manure as well as the use of composted organic wastes as soil amendment for organic matter build up, all for soil rehabilitation and restoration of the badlands in southern Guam. In a companion study we are evaluating the effectiveness of Vetiver technology as a sediment trap to mitigate sediment transport in a typical watershed basin in southern Guam. This paper discusses the methodology as well as up to date data that shows the effect of Vetiver technology on sediment trapping at the watershed level.

  12. How does community context influence coalitions in the formation stage? A multiple case study based on the Community Coalition Action Theory. (United States)

    Kegler, Michelle C; Rigler, Jessica; Honeycutt, Sally


    Community coalitions are rooted in complex and dynamic community systems. Despite recognition that environmental factors affect coalition behavior, few studies have examined how community context impacts coalition formation. Using the Community Coalition Action theory as an organizing framework, the current study employs multiple case study methodology to examine how five domains of community context affect coalitions in the formation stage of coalition development. Domains are history of collaboration, geography, community demographics and economic conditions, community politics and history, and community norms and values. Data were from 8 sites that participated in an evaluation of a healthy cities and communities initiative in California. Twenty-three focus groups were conducted with coalition members, and 76 semi-structured interviews were conducted with local coordinators and coalition leaders. Cross-site analyses were conducted to identify the ways contextual domains influenced selection of the lead agency, coalition membership, staffing and leadership, and coalition processes and structures. History of collaboration influenced all four coalition factors examined, from lead agency selection to coalition structure. Geography influenced coalition formation largely through membership and staffing, whereas the demographic and economic makeup of the community had an impact on coalition membership, staffing, and infrastructure for coalition processes. The influence of community politics, history, norms and values was most noticeable on coalition membership. Findings contribute to an ecologic and theory-based understanding of the range of ways community context influences coalitions in their formative stage.

  14. Combined clinical and home rehabilitation: case report of an integrated knowledge-to-action study in a Dutch rehabilitation stroke unit. (United States)

    Nanninga, Christa S; Postema, Klaas; Schönherr, Marleen C; van Twillert, Sacha; Lettinga, Ant T


    There is growing awareness that the poor uptake of evidence in health care is not a knowledge-transfer problem but rather one of knowledge production. This issue calls for re-examination of the evidence produced and assumptions that underpin existing knowledge-to-action (KTA) activities. Accordingly, it has been advocated that KTA studies should treat research knowledge and local practical knowledge with analytical impartiality. The purpose of this case report is to illustrate the complexities in an evidence-informed improvement process of organized stroke care in a local rehabilitation setting. A participatory action approach was used to co-create knowledge and engage local therapists in a 2-way knowledge translation and multidirectional learning process. Evidence regarding rehabilitation stroke units was applied in a straightforward manner, as the setting met the criteria articulated in stroke unit reviews. Evidence on early supported discharge (ESD) could not be directly applied because of differences in target group and implementation environment between the local and reviewed settings. Early supported discharge was tailored to the needs of patients severely affected by stroke admitted to the local rehabilitation stroke unit by combining clinical and home rehabilitation (CCHR). Local therapists welcomed CCHR because it helped them make their task-specific training truly context specific. Key barriers to implementation were travel time, logistical problems, partitioning walls between financing streams, and legislative procedures. Improving local settings with available evidence is not a straightforward application process but rather a matter of searching, logical reasoning, and creatively working with heterogeneous knowledge sources in partnership with different stakeholders. Multiple organizational levels need to be addressed rather than focusing on therapists as sole site of change. © 2015 American Physical Therapy Association.

  16. A role for INDEPTH Asian sites in translating research to action for non-communicable disease prevention and control: a case study from Ballabgarh, India (United States)

    Krishnan, Anand; Nongkynrih, Baridalyne; Kapoor, Suresh Kumar; Pandav, Chandrakant


    Background The International Network of field sites with continuous Demographic Evaluation of Populations and Their Health (INDEPTH) has 34 Health and Demographic Surveillance System (HDSS) in 17 different low and middle-income countries. Of these, 23 sites are in Africa, 10 sites are in Asia, and one in Oceania. The INDEPTH HDSS sites in Asia identified chronic non-communicable diseases (NCDs) as a neglected area of attention. As a first step, they conducted NCD risk factor surveys within nine sites in five countries. These sites are now looking to broaden the agenda of research on NCDs using the baseline data to inform policy and practice. Methods A conceptual framework for translating research into action for NCDs at INDEPTH sites was developed. This had five steps – assess the problem, understand the nature of the problem, evaluate different interventions in research mode, implement evidence-based interventions in programme mode, and finally, share knowledge and provide leadership to communities and countries. Ballabgarh HDSS site in India has successfully adopted these steps and is used as a case study to demonstrate how this progress was achieved and what factors were responsible for a successful outcome. Results Most of the HDSS sites are in the second step of the process of translating research to action (understand the problem). The conduct of NCD risk factor surveys has enabled an assessment of the burden of NCD risk together with determinants in order to understand the burden at the population level. The experience from Ballabgarh HDSS exemplifies that the following steps – pilot testing the interventions, implementing activities in programme mode, and finally, share knowledge and provide leadership – are also possible in rural settings in low-income countries. The critical success factors identified were involvement of a premier medical institution, pre-existing links to policy makers and programme managers, strong commitment of the HDSS team and

    An unorthodox method of casing drilling used by Tesco Corporation at a gas well in Wyoming to drill deeper using casings as drillpipe is discussed. The process involves either rotating the casing as drill string or using a downhole mud motor to rotate the bit. In this instance, the surface hole and the production hole were casing-drilled to a record 8,312 feet by rotating the casing. The 8 1/2-inch surface hole was drilled with 7-inch casing to 1,200 feet using a Tesco underreamer and a polycrystalline pilot bit; drilling and cementing was completed in 12 1/2 hours. The 6 1/4-inch production hole was drilled with 4 1/2-inch casing and the bottomhole assembly was retrieved after 191 hours rotating. This case was the first in which the entire well was casing-drilled from surface to TD. Penetration rate compared favorably with conventional methods: 12 1/2 hours for casing-drilling to 18.9 hours for conventional drilling, despite the fact that the casing-drilling technology is still in its infancy. It is suggested that casing-drilling has the potential to eliminate the need for the drillpipe entirely. If these expectations were to be realised, casing-drilling could be one of the most radical drilling changes in the history of the oil and gas industry. 1 photo.

  19. Smart Buildings: Business Case and Action Plan

    Energy Technology Data Exchange (ETDEWEB)

    Ehrlich, Paul; Diamond, Rick


    General Services Administration (GSA) has been a pioneer in using Smart Building technologies but it has yet to achieve the full benefits of an integrated, enterprise-wide Smart Building strategy. In July 2008, GSA developed an initial briefing memorandum that identified five actions for a Smart Buildings feasibility study: (1) Identify and cluster the major building systems under consideration for a Smart Buildings initiative; (2) Identify GSA priorities for these clusters; (3) Plan for future adoption of Smart Building strategies by identifying compatible hardware; (4) Develop a framework for implementing and testing Smart Building strategies and converged networks; and (5) Document relevant GSA and industry initiatives in this arena. Based on this briefing memorandum, PBS and FAS retained consultants from Lawrence Berkeley National Laboratory, Noblis, and the Building Intelligence Group to evaluate the potential for Smart Buildings within GSA, and to develop this report. The project has included extensive interviews with GSA staff (See Appendix A), a review of existing GSA standards and documents, and an examination of relevant GSA and industry initiatives. Based on interviews with GSA staff and a review of GSA standards and documents, the project team focused on four goals for evaluating how Smart Building technology can benefit GSA: (1) Achieve Energy Efficiency Mandates--Use Smart Building technology as a tool to meet EISA 2007 and EO 13423 goals for energy efficiency. (2) Enhance Property Management--Deploy enterprise tools for improved Operations and Maintenance (O&M) performance and verification. (3) Implement Network as the Fourth Utility--Utilize a converged broadband network to support Smart Building systems and provide GSA clients with connectivity for voice, data and video. (4) Enhance Safety and Security--Harmonize Physical Access Control Systems (PACS) with Smart Building Systems.

  2. A pharmacy leadership action study. (United States)

    Louie, Clifton; Mertz, Elizabeth; Penfil, Brett; O'Neil, Edward


    To report on the creation of a leadership development program targeted exclusively at pharmacists working in management in the professional community. Large staff-model health maintenance organization (HMO) in California between 2004 and 2008. The Pharmacy Leadership Institute (PLI; a joint effort of the School of Pharmacy and the Center for the Health Professions at the University of California, San Francisco) tested a program in a large staff-model HMO with hundreds of pharmacists in leadership roles. This program included learning seminars, psychometric assessments, leadership goals, intersession activities, coaching/mentoring, and leadership projects. Not applicable. PLI collected survey data in order to evaluate the effectiveness of the institute's leadership development program. In addition, an external evaluator was hired to conduct interviews with the pharmacy directors of the organization which chose to pilot the program. The evaluations from the participants indicate that the leadership development program met many but not all of its initial objectives. Consistent with action research methodology, the faculty of the institute met to redesign some sections of the program in order to meet the established goals. Adjustments were made to different components of the program over the next 4 years. Evaluation data show that these revisions were successful. In addition, follow-up evaluations with participants showed a lasting impact of the program on both individual leadership skills and organizational outcomes. Given the positive outcomes indicated by the evaluation data used in this study, the work of PLI indicates that broader leadership skills can be identified and enhanced within a group of pharmacy managers.

  3. Mode of action of human pharmaceuticals in fish: the effects of the 5-alpha-reductase inhibitor, dutasteride, on reproduction as a case study. (United States)

    Margiotta-Casaluci, Luigi; Hannah, Robert E; Sumpter, John P


    In recent years, a growing number of human pharmaceuticals have been detected in the aquatic environment, generally at low concentrations (sub-ng/L-low μg/L). In most cases, these compounds are characterised by highly specific modes of action, and the evolutionary conservation of drug targets in wildlife species suggests the possibility that pharmaceuticals present in the environment may cause toxicological effects by acting through the same targets as they do in humans. Our research addressed the question of whether or not dutasteride, a pharmaceutical used to treat benign prostatic hyperplasia, may cause adverse effects in a teleost fish, the fathead minnow (Pimephales promelas), by inhibiting the activity of both isoforms of 5α-reductase (5αR), the enzyme that converts testosterone into dihydrotestosterone (DHT). Mammalian pharmacological and toxicological information were used to guide the experimental design and the selection of relevant endpoints, according to the so-called "read-across approach", suggesting that dutasteride may affect male fertility and steroid hormone dynamics. Therefore, a 21-day reproduction study was conducted to determine the effects of dutasteride (10, 32 and 100 μg/L) on fish reproduction. Exposure to dutasteride significantly reduced fecundity of fish and affected several aspects of reproductive endocrine functions in both males and females. However, none of the observed adverse effects occurred at concentrations of exposure lower than 32 μg/L; this, together with the low volume of drug prescribed every year (10.34 kg in the UK in 2011), and the extremely low predicted environmental concentration (0.03 ng/L), suggest that, at present, the potential presence of dutasteride in the environment does not represent a threat to wild fish populations.

  9. To research (or not) that is the question: ethical issues in research when medical care is disrupted by political action: a case study from Eldoret, Kenya. (United States)

    House, Darlene R; Marete, Irene; Meslin, Eric M


    While considerable attention has been focused on understanding the myriad of ethical analysis in international research in low and middle income countries, new issues always arise that have not been anticipated in guidelines or studied extensively. The disruption of medical care arising as a direct result of political actions, including strikes, postelection violence and related activities, is one such issue that leaves physician-researchers struggling to manage often conflicting professional responsibilities. This paper discusses the ethical conflicts that arise for physician-researchers, particularly when disruption threatens the completion of a study or completion is possible but at the expense of not addressing unmet medical needs of patients. We review three pragmatic strategies and the ethical issues arising from each: not starting research, stopping research that has already started, and continuing research already initiated. We argue that during episodes of medical care disruption, research that has been started can be continued only if the ethical standards imposed at the beginning of the study can continue to be met; however, studies that have been approved but not yet started should not begin until the disruption has ended and ethical standards can again be assured.

  10. Effectiveness of assertive case management on repeat self-harm in patients admitted for suicide attempt: Findings from ACTION-J study. (United States)

    Furuno, Taku; Nakagawa, Makiko; Hino, Kosuke; Yamada, Tomoki; Kawashima, Yoshitaka; Matsuoka, Yutaka; Shirakawa, Osamu; Ishizuka, Naoki; Yonemoto, Naohiro; Kawanishi, Chiaki; Hirayasu, Yoshio


    Self-harm is an important risk factor for subsequent suicide and repetition of self-harm, and a common cause of emergency department presentations. However, there still remains limited evidence on intervention in emergency department settings for individuals who self-harm. This multicentre, randomised controlled trial was conducted at 17 general hospitals in Japan. In total, 914 adult patients admitted to emergency departments for a suicide attempt and had a DSM-IV-TR axis I disorder were randomly assigned to two groups, to receive either assertive case management (intervention) or enhanced usual care (control). Assertive case management was introduced by the case manager during emergency department admissions for suicide attempts, and continued after discharge. Interventions were provided until the end of the study period (for at least 18 months and up to 5 years). The number of overall self-harm episodes per person-year was significantly lower in the intervention group (adjusted incidence risk ratio (IRR) 0.88, 95%CI 0.80-0.96, p=0.0031). Subgroup analysis showed a greater reduction of overall self-harm episodes among patients with no previous suicide attempt at baseline (adjusted IRR 0.73, 95% CI 0.53-0.98, p=0.037). Patients younger than 20 years and patients who self-harmed but were not admitted to an emergency department were excluded. The present study showed that assertive case management following emergency admission for a suicide attempt reduced the incident rate of repeat overall self-harm. Copyright © 2017 Elsevier B.V.

  11. Decision Support System integrated with Geographic Information System to target restoration actions in watersheds of arid environment: A case study of Hathmati watershed, Sabarkantha district, Gujarat (United States)

    Patel, Dhruvesh P.; Srivastava, Prashant K.; Gupta, Manika; Nandhakumar, Naresh


    Watershed morphometric analysis is important for controlling floods and planning restoration actions. The present study is focused on the identification of suitable sites for locating water harvesting structures using morphometric analysis and multi-criteria based decision support system. The Hathmati watershed of river Hathmati at Idar taluka, Sabarkantha district, Gujarat is experiencing excessive runoff and soil erosion due to high intensity rainfall. Earth observation dataset such as Digital Elevation Model and Geographic Information System are used in this study to determine the quantitative description of the basin geometry. Several morphometric parameters such as stream length, elongation ratio, bifurcation ratio, drainage density, stream frequency, texture ratio, form factor, circularity ratio, and compactness coefficient are taken into account for prioritization of Hathmati watershed. The overall analysis reveals that Hathmati comprises of 13 mini-watersheds out of which, the watershed number 2 is of utmost priority because it has the highest degradation possibilities. The final results are used to locate the sites suitable for water harvesting structures using geo-visualization technique. After all the analyses, the best possibilities of check dams in the mini-watersheds that can be used for soil and water conservation in the watershed are presented.

  12. Application of the U.S. EPA Mode of Action Framework for Purposes of Guiding Future Research: A Case Study Involving the Oral Carcinogenicity of Hexavalent Chromium (United States)

    Thompson, Chad M.; Haws, Laurie C.; Harris, Mark A.; Gatto, Nicole M.; Proctor, Deborah M.


    Mode of action (MOA) analysis provides a systematic description of key events leading to adverse health effects in animal bioassays for the purpose of informing human health risk assessment. Uncertainties and data gaps identified in the MOA analysis may also be used to guide future research to improve understanding of the MOAs underlying a specific toxic response and foster development of toxicokinetic and toxicodynamic models. An MOA analysis, consistent with approaches outlined in the MOA Framework as described in the Guidelines for Carcinogen Risk Assessment, was conducted to evaluate small intestinal tumors observed in mice chronically exposed to relatively high concentrations of hexavalent chromium (Cr(VI)) in drinking water. Based on review of the literature, key events in the MOA are hypothesized to include saturation of the reductive capacity of the upper gastrointestinal tract, absorption of Cr(VI) into the intestinal epithelium, oxidative stress and inflammation, cell proliferation, direct and/or indirect DNA modification, and mutagenesis. Although available data generally support the plausibility of these key events, several unresolved questions and data gaps were identified, highlighting the need for obtaining critical toxicokinetic and toxicodynamic data in the target tissue and in the low-dose range. Experimental assays that can address these data gaps are discussed along with strategies for comparisons between responsive and nonresponsive tissues and species. This analysis provides a practical application of MOA Framework guidance and is instructive for the design of studies to improve upon the information available for quantitative risk assessment.

  13. The value of the participatory network mapping tool to facilitate and evaluate coordinated action in health promotion networks: two Dutch case studies. (United States)

    Wijenberg, Evianne; Wagemakers, Annemarie; Herens, Marion; Hartog, Franciska den; Koelen, Maria


    Facilitating processes for coordinated action in the field of health promotion is a challenge. Poorthuis and Bijl's (2006) Participatory Network Mapping Tool (PNMT) uses visualization and discussion to map the positions and roles of network actors, stimulate learning processes, and elicit actionable knowledge. This article describes the results from the application of the PNMT in networks of two Dutch health promotion programmes (Health Race and BeweegKuur) with the aim of determining the value of the PNMT to partners in health promotions networks. A qualitative secondary analysis (QSA) was conducted to clarify positions and roles, learning processes, and actionable knowledge of network actors in existing data sets including five group interviews of the Health Race programme and 16 individual interviews and 15 group interviews of the BeweegKuur programme. The PNMT maps both positions and roles of (missing) actors and makes successes (e.g. knowing each other) and challenges (e.g. implementing new activities) visible. Thus, the PNMT provides a starting point for discussion and reflection and eliciting actionable knowledge such as involving new actors and target populations in the programme. The PNMT contributes to the facilitation of coordinated action in health promotion networks by making positions and roles of network partners visible. In combination with dialogue and reflection the PNMT helps to elucidate factors influencing coordinated action and outcomes. The PNMT is valuable in grasping intangible aspects between actors by stimulating collective learning. These insights can be used by researchers and network actors to achieve more successful coordinated action for health promotion.

  14. Action and familiarity effects on self and other expert musicians’ Laban effort-shape analyses of expressive bodily behaviors in instrumental music performance: A case study approach

    Directory of Open Access Journals (Sweden)

    Mary C Broughton


    Full Text Available Self-reflective performance review and expert evaluation are features of Western music performance practice. While music is usually the focus, visual information provided by performing musicians’ expressive bodily behaviors communicates expressiveness to musically trained and untrained observers. Yet, within a seemingly homogenous group such as one of musically trained individuals, diversity of experience exists. Individual differences potentially affect perception of the subtleties of expressive performance, and performers’ effective communication of their expressive intentions. This study aimed to compare self- and other expert musicians’ perception of expressive bodily behaviors observed in marimba performance. We hypothesised that analyses of expressive expressive bodily behaviors differ between expert musicians according to their specialist motor expertise and familiarity with the music. Two professional percussionists and experienced marimba players, and one professional classical singer took part in the study. Participants independently conducted Laban effort-shape analysis – proposing that intentions manifest in bodily activity are understood through shared embodied processes – of a marimbists’ expressive bodily behaviors in an audio-visual performance recording. For one percussionist, this was a self-reflective analysis. The work was unfamiliar to the other percussionist and singer. Perception of the performer’s expressive bodily behaviors differed according to participants’ individual instrumental or vocal motor expertise, and familiarity with the music. Furthermore, individual type of motor experience appeared to direct participants’ attention in approaching the analyses. Findings support forward and inverse perception-action models, and embodied cognitive theory. Implications offer scientific rigour and artistic interest for how performance practitioners can reflectively analyze performance to improve expressive

  3. Youth action research in the marine environment: A case study analysis of selected education projects in Hawai'i, United States of America (United States)

    Zicus, Sandra A.

    The marine environment has always been extremely important to the human inhabitants of the Hawaiian Islands. Today, the ocean environment around Hawai'i is no less important, but it is far more threatened. Coastal and urban development, overfishing, introduction of alien species, and other commercial and recreational uses pose serious risks to coastal and marine ecosystems. There is a recognized need for greater public awareness and understanding of the importance of marine and coastal ecosystems. Involving children actively in the care and management of community resources is an essential factor for long-term societal change in environmental attitudes and behavior. Agencies and organizations in Hawai'i offer a wide range of marine education programs and materials aimed at children. However, there has been little assessment of their overall effectiveness, or analysis of factors that encourage or impede their success. The goal of this research was to begin to address this gap. The first stage of the research examined the perceptions and attitudes of Hawai'i resource managers and educators toward youth involvement in coastal and marine protection, and to answer the question "What is currently being done and by whom?" The second stage examined in detail three different programs that represent a range of approaches and age levels, and include two public charter schools (one elementary and one high school) and a nonprofit after-school program that drew youth from four area high schools. The case study research was conducted over the course of the 2001--2002 school year by means of observations, participant-observations, interviews, focus groups, and reviews of written and electronic media. The case studies were exploratory in nature and differed in their settings, age groups, administration, size, and focus. However, an analysis using the assessment rubric revealed broad patterns common to all three projects. This allowed the development of analytical generalizations

  5. An Interdisciplinary and Intersectoral Action-research Method: Case-Study of Climate Change Adaptation by Cities Using Participatory Web 2.0 Urban Design

    Directory of Open Access Journals (Sweden)

    Geneviève VACHON


    Full Text Available This paper discusses the last segment of a three-year interdisciplinary and intersectoral action research on climate change and urban transformation. The project had, as one of its core missions, the role of imagining urban and architectural adaptations for urban neighbourhoods that would contribute to minimizing the negative impacts of climate change on people’s comfort, health and safety. The first part of the paper describes the collaborative design and augmented participation method used in the context of Québec City, Canada. These include the design process conducted to imagine adaptation scenarios, the visual strategies undertaken to make these understandable for the population, and the Web 2.0 crowdsourcing approach forwarded to measure feasibility and social acceptability of the design and visualization strategies. The second part discusses three positive outcomes of the process. First, collaborative design conducted with intersectoral groups of experts constitutes a promising avenue to identify adaptations and evaluate their relevance. Second, crowdsourcing is a powerful tool to inform the general public about climate change including both negative and potential aspects. As well, the crowdsource model allows access to particular knowledge which empowered users to make changes around their homes and neighbourhoods or advocating action from their local government. Crowdsourcing is also an efficient tool to help understand what people know about the potential impact of climate change and how it bears on their comfort, health and safety. Third and finally, the design proposals and the evaluation comments generated by working closely with various stakeholders, along with the public on-line consultation, allow for the induction of pragmatic recommendations that can be used as decision aids by elected officials and civil servants to better prepare their municipalities for climate change. 

  6. Determining the effects of a professional development program on teachers' inquiry knowledge and classroom action: A case study of a professional development strategy (United States)

    Bell, Cheryl A.

    Science teaching and learning has been the focus of reform efforts for many years. The most recent efforts call for change in the way science is taught and the way students learn science in our nation's classrooms, with an effort to move toward an inquiry-based approach. These efforts present challenges for today's teachers. Many teachers want to do an effective job of teaching science, yet are not sure of what inquiry teaching should look like in the classroom or what they need to change to move toward inquiry-based instruction. The problem posed for the educational community is to identify means to provide teachers with the experiences they need to develop the knowledge and techniques necessary to teach using an inquiry approach in their classrooms. This research addressed this problem by developing a case study of a professional development program designed to enhance the inquiry knowledge and inquiry-based teaching of middle level teachers through the development of leadership teams and peer training. Teachers participated at one of two levels: Level I received intense training at a major university; and Level II received their training from their Level I teammates. Two teams of teachers participated in this research, involving five teachers. The program's effectiveness varied in the changes evident in the teachers' knowledge and use of inquiry in their classrooms. The Level I teachers' knowledge and use of inquiry was influenced by their interpretations of their experiences and how these related to what occurred in their classrooms prior to the institute. Similarly, their interpretation influenced the emphasis placed on including information about inquiry and involving their Level II teammates in inquiry-based instructional experiences during the peer-training sessions. The peer-training session for Team 1 provided a stimulus for the Level II teacher to reflect on her teaching and her students' questions and, consequently, change the level of inquiry in her

    Taylor, Ruth; Thomas-Gregory, Annette


    This article describes case study research for nursing and healthcare practice. Case study research offers the researcher an approach by which a phenomenon can be investigated from multiple perspectives within a bounded context, allowing the researcher to provide a 'thick' description of the phenomenon. Although case study research is a flexible approach for the investigation of complex nursing and healthcare issues, it has methodological challenges, often associated with the multiple methods used in individual studies. These are explored through examples of case study research carried out in practice and education settings. An overview of what constitutes 'good' case study research is proposed.

  9. Understanding communicative actions: a repetitive TMS study. (United States)

    Stolk, Arjen; Noordzij, Matthijs L; Volman, Inge; Verhagen, Lennart; Overeem, Sebastiaan; van Elswijk, Gijs; Bloem, Bas; Hagoort, Peter; Toni, Ivan


    Despite the ambiguity inherent in human communication, people are remarkably efficient in establishing mutual understanding. Studying how people communicate in novel settings provides a window into the mechanisms supporting the human competence to rapidly generate and understand novel shared symbols, a fundamental property of human communication. Previous work indicates that the right posterior superior temporal sulcus (pSTS) is involved when people understand the intended meaning of novel communicative actions. Here, we set out to test whether normal functioning of this cerebral structure is required for understanding novel communicative actions using inhibitory low-frequency repetitive transcranial magnetic stimulation (rTMS). A factorial experimental design contrasted two tightly matched stimulation sites (right pSTS vs left MT+, i.e., a contiguous homotopic task-relevant region) and tasks (a communicative task vs a visual tracking task that used the same sequences of stimuli). Overall task performance was not affected by rTMS, whereas changes in task performance over time were disrupted according to TMS site and task combinations. Namely, rTMS over pSTS led to a diminished ability to improve action understanding on the basis of recent communicative history, while rTMS over MT+ perturbed improvement in visual tracking over trials. These findings qualify the contributions of the right pSTS to human communicative abilities, showing that this region might be necessary for incorporating previous knowledge, accumulated during interactions with a communicative partner, to constrain the inferential process that leads to action understanding.

  12. The case study approach (United States)


    The case study approach allows in-depth, multi-faceted explorations of complex issues in their real-life settings. The value of the case study approach is well recognised in the fields of business, law and policy, but somewhat less so in health services research. Based on our experiences of conducting several health-related case studies, we reflect on the different types of case study design, the specific research questions this approach can help answer, the data sources that tend to be used, and the particular advantages and disadvantages of employing this methodological approach. The paper concludes with key pointers to aid those designing and appraising proposals for conducting case study research, and a checklist to help readers assess the quality of case study reports.

    Diedrich, Juliane; Heymann, William; Leweke, Samuel; Hunt, Stephen; Todd, Robert; Kunert, Christian; Johnson, Will; von Lieres, Eric


    Tentacle resins for IEX are increasingly applied in preparative chromatography for their higher selectivity and higher capacities in comparison to IEX resins without tentacles. However, tentacle resins are often observed to cause unusual elution behavior of monoclonal antibodies under high loading conditions. Understanding this elution behavior is important for a quality by design approach, as it is now mandated by regulatory agencies. A model-based analysis of load, wash and gradient elution is performed for a monoclonal antibody (mAb) on Fractogel SO 3 - . Four experiments with increasing loaded mass show complex peak shapes and formation of a shoulder under overloaded conditions. We hypothesize that the observed peak shapes are caused by mAbs binding in multiple states on the tentacle ion-exchange resin. A new multi-state SMA binding model is used for testing this hypothesis. A two-state binding model is found to quantitatively reproduce all four experiments. An in-depth analysis reveals that the shoulder formation under overloaded conditions can be explained by multi-state binding that particularly manifests in rapid but weak re-adsorption of eluting molecules near the column end. The introduced multi-state SMA model combines features of the so-called spreading model (multiple bound states) and of the standard SMA model (salt dependency). It is by no means limited to ion-exchange chromatography on tentacle resins, but the same concept can be applied for studying systems that are based on other physical mechanisms. The new model can potentially improve mechanistic understanding and facilitate quantitative simulation of various phenomena, such as caused by reorientation, reconformation or unfolding of bound species. Similar concepts can be applied for studying surface-induced aggregation and denaturation. Copyright © 2017 Elsevier B.V. All rights reserved.

  18. A Case of Action-Induced Clonus that Mimicked Action Tremors and was Associated with Cervical Schwannoma

    Directory of Open Access Journals (Sweden)

    Young-Hee Sung


    Full Text Available Clonus is the rhythmic muscle contraction which usually occurs in patients with lesions involving descending motor pathways. Sometimes, rhythmic oscillation of action induced clonus could be confused to action tremor. We report a case of action induced clonus associated with cervical schwannoma which was misdiagnosed as essential tremor. The patient had spasticity in all limbs with exaggerated tendon reflexes, and passive stretch-induced clonus. Imaging and histological examinations revealed a schwannoma extending from C2 to C7. The lesion was partially removed by surgery. Even though essential tremor is a common disease, clinician have to do sufficient neurologic examination considering differential diagnosis.

  19. A study of actions in operative notes. (United States)

    Wang, Yan; Pakhomov, Serguei; Burkart, Nora E; Ryan, James O; Melton, Genevieve B


    Operative notes contain rich information about techniques, instruments, and materials used in procedures. To assist development of effective information extraction (IE) techniques for operative notes, we investigated the sublanguage used to describe actions within the operative report 'procedure description' section. Deep parsing results of 362,310 operative notes with an expanded Stanford parser using the SPECIALIST Lexicon resulted in 200 verbs (92% coverage) including 147 action verbs. Nominal action predicates for each action verb were gathered from WordNet, SPECIALIST Lexicon, New Oxford American Dictionary and Stedman's Medical Dictionary. Coverage gaps were seen in existing lexical, domain, and semantic resources (Unified Medical Language System (UMLS) Metathesaurus, SPECIALIST Lexicon, WordNet and FrameNet). Our findings demonstrate the need to construct surgical domain-specific semantic resources for IE from operative notes.

    Directory of Open Access Journals (Sweden)

    Özgür Kıvılcım Kılınç


    Full Text Available The symptoms which were directly bound to the biochemical mode of action of an herbicide, other symptoms result from an indirect consequence of this action. The symptoms of herbicidal action deeply differed and that the climatic factors during the two first weeks after treatment could change definitely the result of the selective herbicide action. The repetitive observation of symptoms allows to inform the farmer about the tolerance or resistance of certain plant species, including the culture, for instance through the appearance of symptoms on the first leaves of the seedlings and their absence in the following leaves. As a whole, the accurate observation of herbicidal symptoms on plants is the essential, rapid and non-expensive analysis of treatment effectiveness at the field scale. The purpose of the current report is to describe the symptoms of a very complex herbicidal action, that of aclonifen involving two modes of action for the same molecule, approximately at the same concentration, and to compare these symptoms under field conditions and under controlled conditions, for a better understanding.

  5. Studies on promoting action in skin carcinogenesis

    Energy Technology Data Exchange (ETDEWEB)

    Saffiotti, U.; Shubik, P.


    A number of substances were tested for carcinogenic promoting activity in Swiss mice by applying them twice weekly to the clipped dorsal skin, beginning 1 wk after a single application of 9,10-dimethyl-1, 2-benzanthracene (DMBA; 1 to 1.5% in mineral oil). Tests with silver nitrate (10% aqueous), iodoacetic acid (0.9% in acetone, fumaric acid (1% in acetone), ethylphenylpropiolate (5% in acetone), trihydroxymethylanthraquinone. (Emodin; 0.5% in acetone), oleic alcohol, monostearin (5% in acetone) and sorbitan monolaurate were essentially negative; when a single application of croton oil (5% in mineral oil) was interspersed between the carcinogen and silver nitrate, 6/20 mice developed 14 benign tumors and 1 carcinoma. N-Dodecane showed moderate promoting activity (26 tumors, with 2 carcinomas, in 12/30 mice). Tests of several petroleum fractions showed high initial promoting activity (404 tumors, with 31 carcinomas, in 36/50 mice), but the activity disappeared on storage; while there was no carcinogenic activity in mice, in New Zealand albino rabbits the petroleum fractions alone produced considerable numbers of tumors. One application of DMBA, however, did increase tumor incidence and shorten the latent period. The hexane-eluted fraction of a methanolic extract of croton seeds (which had little vesicant activity), had all the promoting activity of the original croton oil; this could be demonstrated with uethan (20 mg/day ip for 5 days) as the initiator as well as with DMBA. In conclusion, the authors distinguish sharply between the promoting activity of compounds such as croton oil, which lead mostly to benign tumors (many of which regress spontaneously), and the additive effects of carcinogenic substances which may have a stimulatory effect on the second stage of carcinogenesis; for this additive carcinogenic effect, they suggest the term developing action. Other studies on croton oil are also reviewed.

    In order to comprehend the impact of music therapy or music therapy processes, a researcher might look for an approach where the topic under investigation can be understood within a broader context. This calls for a rich inclusion of data and consequently a limited number of participants and may...... be achieved through the use of objectivist case study research. The strength of the case study design is that it allows for uncovering or suggesting causal relationships in real-life settings through an intensive and rich collection of data. According to Hilliard (1993), the opposite applies for extensive...... designs, in which a small amount of data is gathered on a large number of subjects. With the richness of data, the intensive design is ―the primary pragmatic reason for engaging in single-case or small N research‖ (p. 374) and for working from an idiographic rather than a nomothetic perspective....

  9. Effectiveness and impact of the cross-border healthcare model as implemented by non-governmental organizations: case study of the malaria control programs by health poverty action on the China-Myanmar border. (United States)

    Zhang, Jun; Dong, Jia-Qiang; Li, Jia-Ying; Zhang, Yue; Tian, Yang-Hui; Sun, Xiao-Ying; Zhang, Guang-Yun; Li, Qing-Pu; Xu, Xiao-Yu; Cai, Tao


    In the Yunnan province of China, 18 counties in six prefectures border Myanmar. Due to its particular combination of geographic features, climate conditions, and cultural landscape, the area provides a suitable environment for the spread of insect-borne diseases such as malaria. In five identified Myanmar Special Regions along the China-Myanmar border, economic development is lagging, people live in extreme poverty, and the healthcare system is fragile. Coupled with political and other reasons, this precludes malaria control work to be effectively carried out in Myanmar, resulting in a heavy burden of the disease. Frequent population movements and favorable conditions for malaria transmission on the border fuel difficulties in controlling and eliminating the spread of the disease in the area. To reduce the prevalence of malaria in the China-Myanmar border area and improve healthcare services for local residents in this particular environment, Health Poverty Action (HPA) has provided malaria aid in the area since the beginning of 2006, as a sub-recipient of the China Global Fund Malaria Programs. In this case study, we examined HPA's activities as part of its malaria control programs in the area, analyzed and summarized the effectiveness and impact of the cross-border healthcare model as implemented by non-governmental organizations, and put forward suggestions for cross-border health aid models and for the prevention of malaria transmission in the Greater Mekong Subregion. HPA had carried out a great quantity of successful malaria control activities in border areas between China and Myanmar, strengthened the partnership and established the collaboration, coordination and cooperation channels among stakeholders. HPA has laid good groundwork and developed its valuable model that could be highlighted and referenced.

  15. Financial and economic determinants of collective action: The case of wastewater management

    Energy Technology Data Exchange (ETDEWEB)

    Brunner, Norbert, E-mail: [Center for Environmental Management and Decision Support, Gregor Mendel Str. 33, A-1180 Vienna (Austria); Starkl, Markus, E-mail: [Competence Centre for Decision-Aid in Environmental Management, University of Natural Resources and Life Sciences/DIB, Gregor Mendel Strasse 33, 1180 Wien (Austria)


    Where public environmental funds support development of wastewater infrastructure, funding institutions ensure the economic use of funds, while the beneficiaries minimize their own costs. In rural areas, there is often a choice between decentralized or centralized (multi-village) systems: if the centralized system is most economic, then only this system is eligible for public funding. However, its implementation requires a voluntary cooperation of the concerned communities, who need to organize themselves to develop and run the infrastructure. The paper analyzes the social determinants of collaboration in a generic case study, using the following variables: method of (economic) assessment, modeled by the social discount rate, funding policy, modeled by the funding rate, and users' self-organization, modeled by cost sharing. In a borderline situation, where the centralized system turns out to be most economic, but this assessment is contingent on the assessment method, collective action may fail: the advantages of collective action from funding are too small to outweigh organizational deficiencies. Considering in this situation sanitation as a human right, authors recommend using innovative forms of organization and, if these fail, reassessing either the amount of funding or the eligibility for funding of more acceptable alternatives. - Highlights: Black-Right-Pointing-Pointer A generic case study models collective action and funding in wastewater management.

Black-Right-Pointing-Pointer Success indicators: conflict rate, funds needed to make cost shares fair. Black-Right-Pointing-Pointer Method for analyzing centralized vs. decentralized disputes.

    Full Text Available This case study was developed from an actual scenario by Dr. Steve Leybourne of Boston University.  The case documents the historical evolution of an organization, and has been used successfully in courses dealing with organizational and cultural change, and the utilization of ‘soft skills’ in project-based management. This is a short case, ideal for classroom use and discussion.  The issues are easily accessible to students, and there is a single wide ranging question that allows for the inclusion of many issues surrounding strategic decision-making, and behavioural and cultural change. Alpha was one of the earlier companies in the USA to invest in large, edge-of-town superstores, with plentiful free vehicle parking, selling food and related household products. Alpha was created in the 1950s as a subsidiary of a major publicly quoted retail group.  It started business by opening a string of very large discount stores in converted industrial and warehouse premises in the south of the United States. In the early days shoppers were offered a limited range of very competitively priced products. When Alpha went public in 1981 it was the fourth largest food retailer in the US, selling an ever-widening range of food and non-food products.  Its success continued to be based on high volume, low margins and good value for money, under the slogan of ‘Alpha Price.’

  3. Leadership development through action learning sets: an evaluation study. (United States)

    Walia, Surinder; Marks-Maran, Di


    This article examines the use of action learning sets in a leadership module delivered by a university in south east England. An evaluation research study was undertaking using survey method to evaluate student engagement with action learning sets, and their value, impact and sustainability. Data were collected through a questionnaire with a mix of Likert-style and open-ended questions and qualitative and quantitative data analysis was undertaken. Findings show that engagement in the action learning sets was very high. Action learning sets also had a positive impact on the development of leadership knowledge and skills and are highly valued by participants. It is likely that they would be sustainable as the majority would recommend action learning to colleagues and would consider taking another module that used action learning sets. When compared to existing literature on action learning, this study offers new insights as there is little empirical literature on student engagement with action learning sets and even less on value and sustainability.

  12. Termination: A Case Study. (United States)

    Friedberg, Ahron L


    In this article I posit and examine certain criteria and qualities for ending an analysis. The case study describes the end phase of a four-year psychoanalysis in which the patient's decision to move to another area forced the end of his analysis. We continued to explore and work through his core neurotic conflicts that included issues of competitive rivalry, dominance and submission, control, and anxiety about birth and death. A shift in the transference from me as a negative father to me as a supportive but competitive older brother was also examined in the context of ending treatment as well as other aspects of the transference. In addition, we analyzed the meaning of his ending treatment based on an extra-analytic circumstance. In discussing this phase of treatment, the definition and history of the term "termination" and its connotations are reviewed. Various criteria for completing an analysis are examined, and technical observations about this phase of treatment are investigated. It was found that while a significant shift in the transference occurred in this phase of the patient's analysis, conflicts related to the transference were not "resolved" in the classical sense. Terminating treatment was considered as a practical matter in which the patient's autonomy and sense of choice were respected and analyzed.

The LSCAPI evaluation proved superiority over LSPI in time, policy learning ability, and effectiveness.

  20. Local Community Studies In Social Studies Course: An Action Research

    Directory of Open Access Journals (Sweden)

    Tuğba Selanik Ay


    Full Text Available Social Studies can be defined as “bonding process based on verification with social reality and dynamic information obtained as a result of this process”. In this context, it is essential to unify the Social Studies course with the real life and to benefit from the society in teaching-learning process in order to enable the learned information to be applied in the real life. In the Social Studies course, students should encounter with the real life itself. Thus, students can produce multidimensional alternative solutions for the cases they encounter and they can explain the best solution with justifications. Considering these arguments, it can be claimed that involving the subjects and studies related to the society and near environment in the Social Studies courses increases the effectiveness of Social Studies teaching. Local community studies, which are associated with the Social Studies program by means of a detailed and good plan, can draw students’ attention and thus permanent learning can occur. In this sense, teachers should benefit from the local community studies in the Social Studies course which reflects the real life.The aim of this study is to determine how local community studies will be applied in Social Studies course in the primary education schools. In line with this aim, the following research questions were addressed:1. How can the activities ofa. benefitting from institutions and organizations in local communitiesb. benefitting from people in local communitiesc. using Internet and library sourcesd. benefitting from special days and current eventswhich are carried out in the Social Studies course taught with local community studies, be arranged?2. Do the local community studies help the students determine the problems in their environments and find out the solutions for these problems?3. What are the students’ opinions about the Social Studies course taught with local community studies ?4. Does the Social Studies

  2. Integrating ethics into case study assignments. (United States)

    Marshall, Pamela A


    I teach an upper-level writing course, Genes, Race, Gender, and Society, designed for Life Science majors, in which I utilize a case study to expose students to ethical ways of thinking. Students first work through the topical case study and then are challenged to rethink their responses through the lenses of ethics, taking into account different ethical frameworks. Students then develop their own case study, integrating ethical components. I want to expose my students to this way of thinking because I see technology being driven by the Jurassic Park phenomenon, "Your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should," and want future physicians grounded in a sense of how their actions relate to the greater good.

    CERN Document Server

    Czelakowski, Janusz


    Action theory is the object of growing attention in a variety of scientific disciplines, and this is the first volume to offer a synthetic view of the range of approaches possible in the topic. The volume focuses on the nexus of formal action theory with a startlingly diverse set of subjects, which range from logic, linguistics, artificial intelligence, and automata theory to jurisprudence, deontology, and economics. It covers semantic, mathematical and logical aspects of action, showing how the problem of action breaks the boundaries of traditional branches of logic located in syntactics and semantics and now lies on lies on the borderline between logical pragmatics and praxeology.   The chapters here focus on specialized tasks in formal action theory, beginning with a thorough description and formalization of the language of action, and moving through material on the differing models of action theory to focus on probabilistic models, the relations of formal action theory to deontic logic, and its key appl...

  14. Nested case-control studies. (United States)

    Ernster, V L


    The nested case-control study design (or the case-control in a cohort study) is described here and compared with other designs, including the classic case-control and cohort studies and the case-cohort study. In the nested case-control study, cases of a disease that occur in a defined cohort are identified and, for each, a specified number of matched controls is selected from among those in the cohort who have not developed the disease by the time of disease occurrence in the case. For many research questions, the nested case-control design potentially offers impressive reductions in costs and efforts of data collection and analysis compared with the full cohort approach, with relatively minor loss in statistical efficiency. The nested case-control design is particularly advantageous for studies of biologic precursors of disease. To advance its prevention research agenda, NIH might be encouraged to maintain a registry of new and existing cohorts, with an inventory of data collected for each; to foster the development of specimen banks; and to serve as a clearinghouse for information about optimal storage conditions for various types of specimens.

  1. Action and Object Word Writing in a Case of Bilingual Aphasia

    Directory of Open Access Journals (Sweden)

    Maria Kambanaros


    Full Text Available We report the spoken and written naming of a bilingual speaker with aphasia in two languages that differ in morphological complexity, orthographic transparency and script Greek and English. AA presented with difficulties in spoken picture naming together with preserved written picture naming for action words in Greek. In English, AA showed similar performance across both tasks for action and object words, i.e. difficulties retrieving action and object names for both spoken and written naming. Our findings support the hypothesis that cognitive processes used for spoken and written naming are independent components of the language system and can be selectively impaired after brain injury. In the case of bilingual speakers, such processes impact on both languages. We conclude grammatical category is an organizing principle in bilingual dysgraphia.

  2. Creating communicative spaces in an action research study. (United States)

    Bevan, Ann L


    To argue that creating communicative spaces in an action research study gave voice to young mothers who may otherwise have remained voiceless. Underpinning the concept of the communicative space in action research is the critical social theory of Jürgen Habermas, in particular, his theory of communicative action and the ideal speech situation. The author argues that in collaborative research, the successful creation of a communicative space is vital in enabling equitable and discursive speech to take place. This is a methodological paper. This approach provided a discursive space to participants who ordinarily may not have interacted, and led to the sharing of different perceptions and understandings that may not otherwise have been possible. This research pointed to the possibility of the ideal speech situation, and the value of opening up a communicative space for researchers and participants. Action research for professionals is a sometimes messy and time-consuming process. However, it is a rewarding approach that uncovers layers of interpretations and understanding that have meaning for the participants involved. The creation of communicative spaces has the potential to enrich nursing research because of its participatory nature, making it more likely that solutions reached will have meaning to people.

  4. Actions Objected at Employees in CSR - Report from the Study

    Directory of Open Access Journals (Sweden)

    Szelągowska-Rudzka Katarzyna


    Full Text Available The study analyzed the essence of the social responsibility of organizations and indicated the areas of actions to which this concept applies in the organizations. Particular attention has been paid to CSR practices objected at employees as key stakeholders of the organization. The purpose of the study was achieved in the form of analysis of CSR practices addressed to employees of the selected organizations in the Pomeranian Voivodeship. It has been confirmed that the study subjects undertake socially responsible actions addressed to their employees. These actions are compliant with the guidelines of ISO 26000 standard in the area of practice in workplace. However, it has been shown that socially responsible objectives are not commonly present in the strategies of these organizations. Personal strategies and the knowledge of the concept of CSR among employees also occur not frequently enough. The presented study is a pilot study. The reached conclusions apply only to the participating organizations. However, it should be noted that the concept of CSR is not yet widely and successfully implemented in organizations within the Pomeranian Voivodeship. It requires further popularizing and intensifying. Also, the practices of CSR addressed to employees should be further improved.

  8. Developing critical thinking through Socratic Questioning: An Action Research Study

    Directory of Open Access Journals (Sweden)

    Husniah Sahamid


    Full Text Available An action research study was conducted among 24 Form 4 level Malaysian students, aged 16. The duration of the study was five months and constituted 16 one-hour literature lessons (short stories from the secondary level Malaysian English Language Upper Secondary Level school syllabus. This paper describes my experience as a teacher-as-researcher to assist students to respond to teacher questions through Paul’s (1993 model of Socratic Questioning which claims to develop students’ critical thinking. Data was collected through researcher’s field notes, students’ writing tasks and student interviews which were analysed after each cycle of the action research study. Changes and adaptations were consequently made based on the data collected and upon teacher reflection to improve practice. The results of this study indicate that repeated practice of Socratic Questioning had a positive effect on student responses and writing tasks. Some of the factors affecting students’ performance included students’ language proficiency, weak reading ability and students’ anxiety towards the questioning method. These issues had to be addressed and dealt with, before Socratic Questioning could be properly implemented in the classroom.

  11. Issues concerning a diagnostic study of an action plan for the San Juan river basin (United States)

    Yamaguchi, Hiromi; Futamura, Hisanori; Nakayama, Mikiyasu


    An action plan is being formulated for the San Juan River basin, shared by Costa Rica and Nicaragua in Central America. The action plan is assumed to be a planning tool designed to ensure the availability of the goods and services that water resources provide for the conservation of ecosystems and for social and economic development. Development of the action plan comprises two phases, namely elaboration of the diagnostic study and drafting of the action plan. The diagnostic study was published in 1997. After examining previous cases in international water systems, for which the diagnostic study was developed as the precursor of an action plan, the author felt that the existing diagnostic study for the San Juan River basin still had room for improvements, in particular in the following aspects: (a) inventory of past, ongoing and future projects; (b) impacts of reserved areas on the basin as a whole; (c) instruments to promote public participation; (d) support by central decision makers; (e) mechanisms for information transparency. These aspects, which need enhancements, seem to suggest that more emphasis should be put on the soft aspects of the sciences. While the diagnostic study addresses issues of natural environment in detail, both data and analysis of human environments are in low profile. The lesson gained from the Zambezi River basin project is that lack of a proper strategy and political commitments by the central decision makers (of the riparian states) will lead to an impasse in implementation of the project, due mainly to paucity of support within basin countries. Lack of support by the general public may also lead to a failure in the implementation phase. These aspects should have been sufficiently addressed in the diagnostic study, so that appropriate actions (to be listed in the action plan) should be elaborated for implementation.

  12. Case Studies in Science Ethics (United States)

    Williams, Karen


    Everyone in science should have ethics education training. I have seen graduate students taken advantage of by their mentors. Many of us have seen misconduct...but what should we do about it? Young scientists are often unaware of the rules in science and make mistakes because of their ignorance of the rules in that particular field of study. Then there are an increasing number of cases in the news of overt cases of misrepresentation in science. All are welcome to attend this discussion of case studies. A case study on topics such as: how to treat data properly, how our values in science affect our work, who gets authorship on scientific papers, who is first author on a paper, what you should do if you uncover misconduct or plagiarism in your university, and we will discuss the scientist's role in society. This will be a painless, non-confrontational small group, then large group discussion of each case

  14. Biological Actions of Artemisinin: Insights from Medicinal Chemistry Studies

    Directory of Open Access Journals (Sweden)

    Jian Li


    Full Text Available Artemisinins have become essential antimalarial drugs for increasingly widespread drug-resistant malaria strains. Although tremendous efforts have been devoted to decipher how this class of molecules works, their exact antimalarial mechanism is still an enigma. Several hypotheses have been proposed to explain their actions, including alkylation of heme by carbon-centered free radicals, interference with proteins such as the sarcoplasmic/endoplasmic calcium ATPase (SERCA, as well as damaging of normal mitochondrial functions. Besides artemisinins, other endoperoxides with various backbones have also been synthesized, some of which showed comparable or even higher antimalarial effects. It is noteworthy that among these artemisinin derivatives, some enantiomers displayed similar in vitro malaria killing efficacy. In this article, the proposed mechanisms of action of artemisinins are reviewed in light of medicinal chemistry findings characterized by efficacy-structure studies, with the hope of gaining more insight into how these potent drugs work.

  15. A study of nootropic drugs for anti-anxiety action. (United States)

    Petkov, V D; Getova, D; Mosharrof, A H


    The effects of adafenoxate (100 mg/kg), aniracetam (50 mg/kg), meclofenoxate (100 mg/kg), piracetam (250 mg/kg), and standardized ginseng extract-G115 (100 mg/kg) applied for five days were studied with Vogel's conflict procedure in which thirsty naive rats were periodically administered shocks for licking water. The results showed a significant anti-anxiety effect (increases in licking) with adafenoxate and meclofenoxate. Piracetam significantly suppressed licking behaviour and this effect was evaluated as anxiogenic (resulting from the non-specific stimulant action of the drug). Adafenoxate was found to increase also the number of entries into and escapes from the dark compartment without punishment responding. This effect of adafenoxate was considered to be an expression of facilitated conditioned-reflex activity. A beneficial role for the observed anti-anxiety effects of adafenoxate and meclofenoxate in the nootropic action of these drugs is suggested.

  16. Transformational leadership and shared governance: an action study. (United States)

    Bamford-Wade, Anita; Moss, Cheryle


    The present study demonstrates the practical relevance of the concepts of transformational leadership as a Director of Nursing working with structure (shared governance) and active processes, informed by action research, to achieve the incremental breakthroughs associated with culture change in nursing. Responding to the context of a decade of health reforms in a New Zealand tertiary hospital, the leadership challenge, as a Director of Nursing, was to find ways of transforming the nursing workforce. How could nursing evolve from a relatively disempowered position within the organization (impact of the reforms) and reshape to achieve effectiveness within the new organizational culture? Interwoven with transformational leadership are action processes progressively moving forward through cycles of reconnaissance, planning, implementation and evaluation. The principles of shared governance 'partnership', 'equity', 'accountability' and 'ownership' underpin and work synchronically with the active processes in advancing the effectiveness of nursing. It is leadership for and in action. This study is descriptive and exploratory overall, and more specifically it uses reflective practice and self-reporting as methods. The outcomes of transformational leadership are evident in a confident, competent and committed nursing workforce which embraces continuous learning and expresses a professional respect for each other. The practical inter-weaving of the concepts of transformational leadership, shared governance and action processes provide a framework for sustainable change processes both at a unit and organizational level. It is the interplay between the three concepts that generates a process of creative innovation, questioning and challenging existing structures to try and reach a new level of excellence through the participation and valuing of nurses and nursing practice. © 2010 The Authors.

  20. Strengthening Interprofessional Requirements Engineering Through Action Sheets: A Pilot Study. (United States)

    Kunz, Aline; Pohlmann, Sabrina; Heinze, Oliver; Brandner, Antje; Reiß, Christina; Kamradt, Martina; Szecsenyi, Joachim; Ose, Dominik


    The importance of information and communication technology for healthcare is steadily growing. Newly developed tools are addressing different user groups: physicians, other health care professionals, social workers, patients, and family members. Since often many different actors with different expertise and perspectives are involved in the development process it can be a challenge to integrate the user-reported requirements of those heterogeneous user groups. Nevertheless, the understanding and consideration of user requirements is the prerequisite of building a feasible technical solution. In the course of the presented project it proved to be difficult to gain clear action steps and priorities for the development process out of the primary requirements compilation. Even if a regular exchange between involved teams took place there was a lack of a common language. The objective of this paper is to show how the already existing requirements catalog was subdivided into specific, prioritized, and coherent working packages and the cooperation of multiple interprofessional teams within one development project was reorganized at the same time. In the case presented, the manner of cooperation was reorganized and a new instrument called an Action Sheet was implemented. This paper introduces the newly developed methodology which was meant to smooth the development of a user-centered software product and to restructure interprofessional cooperation. There were 10 focus groups in which views of patients with colorectal cancer, physicians, and other health care professionals were collected in order to create a requirements catalog for developing a personal electronic health record. Data were audio- and videotaped, transcribed verbatim, and thematically analyzed. Afterwards, the requirements catalog was reorganized in the form of Action Sheets which supported the interprofessional cooperation referring to the development process of a personal electronic health record for the

    Full Text Available Introduction. Chronic post-anoxic myoclonus, also known as Lance-Adams syndrome, may develop following hypoxic brain injury, and is resistant to pharmacological therapy. Case report. The patient we presented developed post-anoxic action myoclonus with severe, completely incapacitating myoclonic jerks. Myoclonus did not respond to the treatment with commonly used agents, i.e. valproate and clonazepam alone or in combination. Improvement of the action myoclonus was observed only after adding levetiracetam. Conclusion.

    Fluoride has been widely used for the prevention of dental caries since the mid-20th century. The aim of this study was to investigate the chronologic trends in studies on fluoride mechanisms of action against dental caries during the years 1950 to 2015. To this aim, queries such as "fluoride," "fluoride and demineralization," "fluoride and remineralization," "fluoride and (plaque or biofilms)," and "fluoride and (bacteria or microbials)" were submitted to PubMed to collect research article information, including titles, abstracts, publication dates, author affiliations, and publication journals. The article information that PubMed produced was then collected by an automatic web crawler and examined through informetrics and linguistic analyses. We found that the number of articles concerned with fluoride mechanisms of action against dental caries was 6,903 and gradually increased over time during the years 1950 to 2015. They were published by 1,136 journals-most notably, Caries Research and Journal of Dental Research. Of the articles published, those related to bacteria/microbials had a higher percentage (44%) than those dealing with plaque/biofilms, demineralization, and remineralization. With regard to the geographic distribution of authors, Europe and North America accounted for 65% of the articles during the years 1987 to 2015, although the number of authors in Asia sharply increased in recent years. Among the fluoride compounds, NaF was mentioned more frequently than SnF2, Na2PO3F, amine fluoride, and acidulated phosphate fluoride during the years 1986 to 2015. Water fluoridation received the most attention among the various fluoride application methods (toothpastes, mouthwashes, fluoride varnishes, and fluoride gels) during the same period. These results, obtained from employing informetrics and linguistic analyses, suggest that in studies on fluoride mechanisms of action, 1) the unbalanced geographic distribution of articles and 2) the heavy concentration of

    Full Text Available La recherche-action comporte deux caractéristiques principales : elle met en œuvre la collaboration entre plusieurs types d’acteurs et vise une transformation de la réalité sociale. Elle possède des forces et des faiblesses différentes de la recherche à objectif strictement cognitif. L’article rend compte d’une recherche-action menée par des sociologues, des intervenants sociaux et des populations vivant en squats en Ile-de-France. Les auteurs analysent les enjeux méthodologiques qui se sont posés sur ce terrain particulier relevant de la sociologie de la déviance. Ceux-ci sont liés, notamment, à la participation de chaque groupe d’acteurs aux différentes étapes de la recherche, à la présence d’intérêts différents portés par chacun d’entre eux, et à la conciliation entre les principes habituellement de rigueur dans l’enquête sociologique et les principes de la recherche-action.Research-Action has two main objectives: to allow different players to cooperate, and to transform social reality. This methodology has both the strengths and the weaknesses of strictly cognitive research. In this article, the authors discuss a research-action project which brought together sociologists, social workers and squatters from the Ile-de-France region (Paris and surrounding region. Methodological issues that arise specifically in the context of deviance are addressed, notably the participation of the different players at different stages of the research project, their different areas of interest, as well as the reconciliation between more conventional sociological research and the principles of research-action.

    Full Text Available This paper was commissioned by Professor Gernot Wersig of the Freie Universität, Berlin in 1980, as part of his Project, Methodeninstrumentarium zur Benutzforschung in Information und Dokumentation. It attempted to set out what was, for the time, a novel perspective on appropriate methodologies for the study of human information seeking behaviour, focusing on qualitative methods and action research, arguing that the application of information research depended up its adoption into the managerial processes of organizations, rather than its self-evident relationship to any body of theory.

  6. The use of conferencing technologies to support drug policy group knowledge exchange processes: an action case approach. (United States)

    Househ, Mowafa Said; Kushniruk, Andre; Maclure, Malcolm; Carleton, Bruce; Cloutier-Fisher, Denise


    To describe experiences, lessons and the implications related to the use of conferencing technology to support three drug policy research groups within a three-year period, using the action case research method. An action case research field study was executed. Three different drug policy groups participated: research, educator, and decision-maker task groups. There were a total of 61 participants in the study. The study was conducted between 2004 and 2007. Each group used audio-teleconferencing, web-conferencing or both to support their knowledge exchange activities. Data were collected over three years and consisted of observation notes, interviews, and meeting transcripts. Content analysis was used to analyze the data using NIVIO qualitative data analysis software. The study found six key lessons regarding the impact of conferencing technologies on knowledge exchange within drug policy groups. We found that 1) groups adapt to technology to facilitate group communication, 2) web-conferencing communication is optimal under certain conditions, 3) audio conferencing is convenient, 4) web-conferencing forces group interactions to be "within text", 5) facilitation contributes to successful knowledge exchange, and 6) technology impacts information sharing. This study highlights lessons related to the use of conferencing technologies to support distant knowledge exchange within drug policy groups. Key lessons from this study can be used by drug policy groups to support successful knowledge exchange activities using conferencing technologies. 2010 Elsevier Ireland Ltd. All rights reserved.

  15. Repetitive compound muscle action potentials in electrophysiological diagnosis of congenital myasthenic syndromes: A case report and review of literature

    Directory of Open Access Journals (Sweden)

    Kumar R


    Full Text Available Congenital myasthenic syndromes (CMSs are a heterogeneous group of disorders, characterized by dysfunction of neuromuscular junction (NMJ transmission. These syndromes are genetically inherited and are present since birth. Some have characteristic clinical or electrodiagnostic features but in many cases determination of the specific form requires genetic studies or specialized morphological and electrophysiological studies on muscle tissue. We report a case of a 4-year-old boy with progressive ptosis and limitation of ocular movements who was diagnosed as slow-channel CMS based on the characteristic electrodiagnostic features. Repetitive compound muscle action potentials (R-CMAPs were recorded after single nerve stimulus, with decremental response after repetitive trains performed at 3 Hz. CMSs are at times clinically difficult to distinguish from acquired myasthenia. The characteristic clinical and electrodiagnostic features help in the diagnosis and enable rational therapy. In this article we discuss the characteristics of synaptic R-CMAPs.

    Smyth, J D; Quinn, R D [Pacific Northwest Lab., Richland, WA (USA); Gianti, S J [CH2M Hill, Reston, VA (USA)


    Accelerated actions were developed by the Environmental Protection Agency (EPA) within the regulatory framework for initiating early cleanup action or accelerating ongoing cleanup action to abate, mitigate, or reduce risk to human health or the environment at a contaminated waste site. The purposes of this report are to review the regulatory frameworks available to initiate accelerated actions at sites on the National Priorities List (NPL) and to provide case histories of sites where accelerated actions have been implemented. The findings of this report are applicable to non-NPL waste sites also. Accelerated actions are of interest to the Department of Energy (DOE) for two primary reasons: they are methods available to demonstrate progress in environmental restoration at DOE waste sites, and a subset of accelerated actions, termed interim remedial actions, may be required in place of final actions to avoid violating National Environmental Policy Act (NEPA) guidelines during the development of DOE Office of Environmental Restoration and Waste Management's (DOE- EM's) Programmatic Environmental Impact Statement (PEIS). To provide the case histories, interviews with staff and reviews of compliance documents were conducted for sites in EPA Regions 3, 4, and 7. 12 refs., 1 fig.

  2. Spectroscopic studies and photodynamic actions of hypocrellin B in liposomes. (United States)

    Yu, C; Chen, S; Zhang, M; Shen, T


    Hypocrellin B (HB), a lipid-soluble natural pigment of perylenequinone derivative, is considered as potential photosensitizer for photodynamic therapy. Liposomes loaded with HB can constitute a simple model system, appropriate for better understanding the photodynamic action of HB in vivo. The steady-state absorption and emission spectra, quantum yield and lifetime of fluorescence of HB incorporated into egg L-a-phosphatidyl-choline (EPC) liposome were examined. The photochemical properties (Type I and/or Type II) of HB have also been studied in aqueous dispersions of small unilamellar liposomes of EPC using electron paramagnetic resonance and spectrophotometric methods, respectively. The quantum yield of 1O2 generated by HB is ca 0.76 in chloroform solution and it did not change upon the incorporation of HB into liposomes of EPC. The superoxide anion radical was generated by the electron transfer from the anion radical of HB (HB.-) to oxygen. The disproportionation of O2.- can generate H2O2 and ultimately the highly reactive .OH via the Fenton reaction. It could be that the disproportionation proceeded too fast, so we could not detect O2.- directly in aqueous dispersions of liposome EPC. Moreover, the self-sensitized photooxygenation of HB embedded in liposomes was studied, and almost fully (87%) inhibiting this reaction of HB by p-benzoquinone (as the quencher of O2.-) in aqueous dispersion of liposome EPC indicated that the radical mechanism (Type I) might be mainly involved in this oxygenation. All these findings suggested that the photodynamic action of HB proceeded via both Type-I and -II mechanisms, but Type-I mechanism might play a more important role in the aqueous dispersion.

    Taušl Procházková Petra


    Full Text Available Entrepreneurial ecosystem is recently in increasing focus of scholars. There are several members of the entrepreneurial ecosystem shifting towards an entrepreneurial society. This paper explores how various regional members inside of the ecosystem are helping in spreading the entrepreneurial thoughts and shifting individuals and the general opinion from managed economy towards an entrepreneurial society. To unpack these activities inside of the entrepreneurial ecosystem, first the understanding of ecosystem and its dimensions is conceptualized. Then a case study is provided. The case study examines regional activities of several ecosystem players. The findings highlight several aspects regarding the entrepreneurial ecosystem and activities fostering its flourishing. Rather than focus on a comprehensive study about effectiveness of public policy makers, the paper concentrate on examining and mainly understanding some representatives of the ecosystem. These individuals are understood as a means to promote and support entrepreneurial society, ecosystem.

  4. Action anticipation beyond the action observation network: a functional magnetic resonance imaging study in expert basketball players. (United States)

    Abreu, A M; Macaluso, E; Azevedo, R T; Cesari, P; Urgesi, C; Aglioti, S M


    The ability to predict the actions of others is quintessential for effective social interactions, particularly in competitive contexts (e.g. in sport) when knowledge about upcoming movements allows anticipating rather than reacting to opponents. Studies suggest that we predict what others are doing by using our own motor system as an internal forward model and that the fronto-parietal action observation network (AON) is fundamental for this ability. However, multiple-duty cells dealing with action perception and execution have been found in a variety of cortical regions. Here we used functional magnetic resonance imaging to explore, in expert basketball athletes and novices, whether the ability to make early predictions about the fate of sport-specific actions (i.e. free throws) is underpinned by neural regions beyond the classical AON. We found that, although involved in action prediction, the fronto-parietal AON was similarly activated in novices and experts. Importantly, athletes exhibited relatively greater activity in the extrastriate body area during the prediction task, probably due to their expert reading of the observed action kinematics. Moreover, experts exhibited higher activation in the bilateral inferior frontal gyrus and in the right anterior insular cortex when producing errors, suggesting that they might become aware of their own errors. Correct action prediction induced higher posterior insular cortex activity in experts and higher orbito-frontal activity in novices, suggesting that body awareness is important for performance monitoring in experts, whereas novices rely more on higher-order decision-making strategies. This functional reorganization highlights the tight relationship between action anticipation, error awareness and motor expertise leading to body-related processing and differences in decision-making processes. © 2012 The Authors.

  5. Data Integrity-A Study of Current Regulatory Thinking and Action. (United States)

    Shafiei, Nader; De Montardy, Regis; Rivera-Martinez, Edwin


    In reaction to breaches of data integrity in the pharmaceutical industry, regulatory authorities have introduced inspection approaches or initiatives with the aim of reducing occurrences of data integrity problems. This review article-based on study of 65 cases of regulatory action from 2002 to 2014-provides an overview of current regulatory thinking and action on breaches of data integrity affecting GxP (health-related regulations) processes supporting non-clinical studies, clinical studies, laboratory controls, and production controls. These case studies largely represent position of the U.S. Food and Drug Administration and the regulatory agencies affiliated with the European Medicines Agency. Also discussed is the role of human factors as a potential source of data integrity problems. The article concludes by recommending some remedial controls that could be established to avoid or reduce occurrences of data integrity problems.Lay Abstract: In fulfilling their mission to protect public health, regulatory agencies (e.g., U.S. Food and Drug Administration, European Medicines Agency) must establish confidence that medical products they approve are fit for their intended use. In so doing they rely on scientific and operational data generated during research, development, manufacturing, sales, marketing, distribution, and post-marketing surveillance activities. The level of confidence they build is directly proportional to the scientific validity and integrity of data presented to them by the sponsors of medical products. In this article we present analysis of 65 case studies that document regulatory action taken by various regulatory agencies on breach of data integrity between 2002 and 2014. The ensuing discussion on current trends largely represents position of the U.S. Food and Drug Administration and European Medicines Agency. The article concludes by proposing some remedial controls that could be established by pharmaceutical companies to avoid or reduce

  7. Facial nerve action potentials: a study to assess waveform reliability. (United States)

    Axon, P R; Ramsden, R T


    To assess the reliability of the orthodromic facial nerve action potential (FNAP), recorded from the intratemporal portion of the facial nerve on stimulation within the cerebellopontine angle. Prospective study. Tertiary referral center. Ten consecutive patients undergoing translabyrinthine resection of vestibular schwannoma. Diagnostic. Ten consecutive FNAPs were recorded on stimulation of the facial nerve within the cerebellopontine angle. The FNAP recording probe was placed directly on the nerve surface after the fallopian canal was opened at the second genu. Ten consecutive compound muscle action potentials (CMAPs) were recorded simultaneously from surface electrodes overlying the facial musculature, by use of a standardized electrode placement technique. The stimulating and recording equipment were removed (excluding CMAP surface electrodes) and reapplied, and FNAP and CMAP data were recorded for a second time (test/retest). Peak-to-peak amplitudes of all waveforms were calculated. The average FNAP peak-to-peak amplitude for all patients was larger than the CMAP peak-to-peak amplitude (2.60 mV and 1.07 mV, respectively). Random effects analysis of variance was performed to assess the individual components of variation. This showed that CMAP was less variable than FNAP for replicate error (10 consecutive FNAPs and CMAPs) and test/retest error. However, subject variance was less for FNAP, where subject variance was by far the largest contributor to overall variation. The reliability coefficient for FNAP was 0.995 and for the CMAP was 0.982, where absolute reliability is 1.0. These data confirm that the FNAP, recorded by the technique described here, is a reliable waveform when compared with the CMAP and is a valid method for assessing facial nerve function.

  14. Maternal hyperthyroidism after intrauterine insemination due to hypertrophic action of human chorionic gonadotropin: a case report. (United States)

    Bakas, P; Tzouma, C; Creatsa, M; Boutas, I; Hassiakos, D


    To report a rare case of maternal hyperthyroidism after intrauterine insemination due to hypertrophic action of hCG. A 36-year-old woman after successful intrauterine insemination and triplet pregnancy, developed hyperthyroidism with resistance to medical treatment. All signs of hyperthyroidism resolved and the results of thyroid function tests returned to normal without any medication after embryo meiosis. De novo maternal hyperthyroidism may develop during pregnancy as a result of pathological stimulation of the thyroid gland from the high levels of hCG hormone that can be seen in multiple pregnancies. The risk of hyperthyroidism is related to the number of fetuses. Reversibility of symptomatology can be seen after fetal reduction of multiple pregnancies.

  15. A case study of Impetigo

    Directory of Open Access Journals (Sweden)

    Mansouri P


    Full Text Available This is a report of a case study on 234 patients with impetigo who referred to Razi Dermatology Hospital from April to November, 1989. Treatment was started immediately after obtaining direct smear and performing culture and antibiotic sensitivity test. The most common organism responsible for impetigo was the coagulase-positive staphylococcus (71%. In 13.7% of the cases, the coagulase-negative staphylococcus was grown on culture media, but none of the cultures showed streptococcus as the main organism. Treatment was started with oral penicillin V, oral erythromycin, benzathine penicillin G injection, oral cephalexin, and topical fuccidin. Clinical and bacteriological evaluation after 3-7 days showed that it is preferable to use oral cephalexin instead of other protocols such as oral erythromycin, which has previously been the drug of choice for impetigo. In addition, topical fuccidin with a 75% curative rate was the first drug for treatment, with the same effect as the oral cephalexin

  16. Lessons from the Look Action for Health in Diabetes Study

    Directory of Open Access Journals (Sweden)

    Mary T Korytkowski


    Full Text Available The Look Action for Health in Diabetes AHEAD Study was designed as a long-term randomized controlled clinical trial and powered to detect differences in cardiovascular outcomes, the primary cause of early morbidity and mortality in type 2 diabetes, among subjects randomized to receive an intensive lifestyle intervention or a control group of diabetes support and education. The study was terminated early due to the absence of any difference in the primary outcome, defined as a composite of the first postrandomization occurrence of fatal and nonfatal myocardial infarction and stroke, or angina requiring hospitalization. However, important secondary favorable outcomes were observed in those receiving the intensive lifestyle intervention. This included more weight loss, greater fitness, less disability, less depression, reductions in sleep apnea and urinary incontinence, better glycemic control, and more subjects experiencing diabetes remission. These results underscore the importance of lifestyle interventions as a component of diabetes therapy. Long-term follow-up of Look AHEAD participants is planned, despite discontinuation of the intensive lifestyle program.

    Pisarev, M A; Krawiec, L; Juvenal, G J; Bocanera, L V; Pregliasco, L B; Sartorio, G; Chester, H A


    The thyroid gland synthesizes 6-delta-iodolactone, a compound shown to inhibit goiter growth in vivo and cell proliferation in culture. The present studies were performed to characterize this effect further with the aim of exploring the possible therapeutic action of iodolactones. Prevention assay: rats were treated simultaneously with a goitrogen, methylmercaptoimidazole, and either 6-delta-iodo-lactone or 14-iodo-omega-lactone, a synthetic derivative, given either i.p. or p. o. Both compounds caused a significant decrease in thyroid weight irrespective of the route of administration, but oral administration was less effective. A dose-response relationship was observed, the minimal effective dose (i.p.) being 3 micrograms/day. Involution assay: goiter was first induced with methylmercaptoimidazole and then the iodolactones were injected. Both compounds caused a significant involution, which was dose-related. Acute (10 days) administration of the iodolactones did not produce significant changes in several serum parameters (total T3 and T4, cholesterol, total protein, urea and acetylcholinesterase). These results give further support to the potential therapeutic application of iodolactones.

  19. Evaluating a problem based learning course: an action research study. (United States)

    Walker, J; Bailey, S; Brasell-Brian, R; Gould, S


    Problem based learning (PBL) has been widely used in the United States, United Kingdom and Australasia in undergraduate nursing education to develop critical thinking and problem solving skills. PBL has been used since 1996 in a Bachelor of Nursing course at a New Zealand tertiary institution, and several modifications have been made to foster effective learning. The 'pure' PBL process has been adapted to move students gradually from teacher direction to taking responsibility for their learning. This has provided the opportunity for students to develop critical thinking, problem solving, information retrieval and evaluation skills, and group process skills over an 18-week period. Because rigorous evaluation of these changes had not been formally undertaken, the purpose of this study was to evaluate how the current format was developing students' understanding and integration of knowledge. Two cycles of the action research method (Cardno and Piggot-Irvine, 1994) were used, involving 4 lecturers and 17 students. Data was collected both quantitatively and qualitatively over a 16-week period. Findings indicated the importance of: explaining the purpose and process of PBL; communicating in detail the role of both students and lecturers; keeping communication lines open; addressing timetabling issues and valuing this method of learning for nursing practice. Implications for nursing education are addressed.

Multiple personality disorder is characterised by splited individual ego-states and splited professional community arguing whether this disorder actually exists or not.Methods. In this case report study a supportive psychodynamic psychotherapy of a patient with multiple personality disorder is presented, that lasted for 4.5 years and resulted in ego-reintegration.Conclusions. The spliting between different ego-states is powered by unneutralised aggression with the possibility of hetero- and autoaggressive behaviour. Therefore the patient in the analytically oriented psychotherapeutic process is at high risk and a safe therapeutic (e. g. in-patient setting has to be provided.

    Beatriz Edra


    Full Text Available The importance of waste management in hospitals is indisputable in preserving the environment and protecting public health, but management models are rarely discussed. This study presents the legal and conceptual frameworks of good waste management practices applicable to hospitals and associated indicators. As a case study, the overall performance of Hospital Centre of São João, in Porto, was analysed based on published reports. Data on the production of waste in their different typologies were collected from 2010 to 2016, enabling a correlation of the waste production with the kg/bed/day indicator. The aim of this study was to gather data and discuss trends in a real scenario of evolution over a six-year period in order to contribute to a future research proposal on indicators that can be used as reference for benchmarking the construction of methodological guides for hospital waste management.

  5. The feasibility of localised strike action by educators in cases of learner misconduct

    Directory of Open Access Journals (Sweden)

    J P Rossouw


    Full Text Available Developments in South African labour legislation since the inception of the new democracy indicate serious attempts by the legislators to protect the interests of employees. The Bill of Rights has, concurrently, enshrined a variety of fundamental rights that, in principle, offer protection in the workplace. Despite this established, protective legal framework, South African schools regularly witness incidents where fundamental rights of educators are infringed. Numerous educators are currently convinced that their rights are put second to the rights of learners, even in cases of physical or psychological violence against them. Where ineffective enforcement of legislation by the state occurs, educators' security is undermined. This article explores various ways of compelling the employer to enforce existing legislation effectively against learner delinquency that may impact on the security of a specific group of educators. The basic claim of the article is that industrial action by educators in the form of localised strikes is feasible, provided that all other remedies have been exhausted. It is concluded that justice should be visibly reinstated by the state as employer, in all cases where educators' right to security are violated

    The Department of Energy's (DOE) Office of Site Closure, EM-30, houses the document library pertaining to sites that are related to the Formerly Utilized Sites Remedial Action Program (FUSRAP) and regularly addresses ongoing information demands, primarily from Freedom of Information Act (FOIA) requests, interested members of the public, the DOE, and other Federal Agencies. To address these demands more efficiently, DOE has begun to implement a new multi-phase, information management process known as e-FUSRAP. The first phase of e-FUSRAP, the development of the Considered Sites Database, summarizes and allows public access to complex information on over 600 sites considered as candidates for FUSRAP. The second phase of e-FUSRAP, the development of the Document Indexing Database, will create an internal index of more than 10,000 documents in the FUSRAP library's case file, allowing more effective management and retrieval of case file documents. Together, the phases of e-FUSRAP will allow EM-30 to become an innovative leader in enhancing public information sources.

  7. Physiologic amputation: a case study. (United States)

    Long, Jeri; Hall, Virginia


    Acute limb ischemia is a complication of severe peripheral arterial disease that can be a threatening limb as well as life. Multiple procedures exist today to help revascularize extremities; however, even with the latest technologies, surgical amputation of the limb may still be necessary. Cryoamputation, or physiologic amputation, is a method used to treat patients who are hemodynamically unstable for the operating room and who are in need of urgent amputation owing to arterial ischemia. This procedure is used in the rare instance where not only a persons' limb is threatened, but also their life. This is a case study regarding one patient who presented to the hospital with limb-threatening ischemia who became hemodynamically unstable owing to the rhabdomyolysis associated with the ischemia of his lower extremity. Cryoamputation was used to stabilize the patient and prevent further deterioration, so that he could safely undergo surgical amputation of the limb without an increase in mortality risk. Cryoamputation must be followed by formal surgical amputation when the patient is hemodynamically stabilized. It is not a limb salvaging, procedure but it is a life-saving procedure. This case study demonstrates the usefulness of the procedure and discusses the technique used for cryoamputation. Copyright © 2014 Society for Vascular Nursing, Inc. Published by Mosby, Inc.

  9. Modelling farmers' action: decision rules capture methodology and formalisation structure: a case of biomass flow operations in dairy farms of a tropical island. (United States)

    Vayssières, J; Lecomte, P; Guerrin, F; Nidumolu, U B


    Studies on decision-making processes are generally aimed at identifying farmers' needs and predicting farmers' reactions to technical innovations. In the present paper we study these decision-making processes, with reference to dairy farms, to build a whole-farm computer model (WFM) which simulates farmers' actions. In this study, (i) a multi-tool and multi-step methodology is proposed, which can also be qualified as an iterative and interactive methodology to reveal decision rules and (ii) a generic structure to formalise how action is conducted, termed 'structure for action modelling' (SAM). In the case of forage crop-dairy cattle systems, we have tested the current methodology to capture the decision rules and the SAM to represent action concerning farm management. An 'immersion' approach, inspired by the ethnographic approach has been adapted to access operational technical decisions (taken on a daily basis). This study helped in understanding how detailed and large approaches can be complementary and can facilitate identification of what can be generalised in a conceptual model. To define the generic structure (SAM), a set of descriptive variables concerning technical operations has been selected. The conceptual model generated is composed of decision rules reconstructed by researchers with farmers' committed participation. The validation method is based on participatory approaches and on comparing of actions simulated by the model with practices on the ground. Not contesting the fact that farmers plan their action, this study also revealed the importance of adjustments in action. For example, 20 to 55% of the time the planned food ration is not distributed to the milking cows because of forage unavailability. We also discuss how this structure can facilitate integration of decision mechanisms in biophysical models and how such an integration of adjustment decision rules can produce more realistic simulations of technical actions.

  10. The case study of biomaterials and biominerals (United States)

    Del Hoyo Martínez, Carmen


    The teaching of biomaterials as case study by on-line platform , susceptible to develop both individually and in groups, got different objectives proposed by the European Higher Education System, among which include: participate actively in the teaching-learning process by students, interpreting situations, adapt processes and solutions. It also improves oral and written communication, analytical skills and synthesis and also the ability to think critically. Biomaterials have their origin in biominerals. These are solid inorganic compounds of defined structure, consisting of molecular control mechanisms that operate in biological systems. Its main functions are: structural support, a reservoir of essential elements, sensors, mechanical protection and storage of toxic elements. Following the demand of materials compatible with certain functional systems of our body, developed biomaterials. Always meet the condition of biocompatibility. Should be tolerated by the body and do not provoke rejection. This involves a comprehensive study of physiological conditions and the anatomy of the body where a biomaterial has to be implemented. The possibility of generating new materials from biominerals has a major impact in medicine and other fields could reach as geology, construction, crystallography, etc. While the study of these issues is in its infancy today, can be viewed as an impact on the art and future technology. Planning case study that students would prepare its report for discussion in subgroups. Occurs then the pooling of individual analysis, joint case discussion and adoption by the subgroup of a consensual solution to the problem. The teacher as facilitator and coordinator of the final case analysis, sharing leads to group-wide class and said the unanimous decision reached by the students and gives his opinion on the resolution of the case.

  16. Hope and Anger as Mediators Between Collective Action Frames and Participation in Collective Mobilization: The Case of 15-M

    Directory of Open Access Journals (Sweden)

    Anna Wlodarczyk


    Full Text Available The study set out to integrate collective action models and emphasize the role of emotions. Whereas the importance of anger is indisputable, relatively little attention has been paid to the role of positive emotions, such as hope, in collective action research. Hence, the aim of the study was to explore the role of hope and anger as drivers of participation and involvement in collective mobilizations. A cross-sectional field study (N = 638 conducted right after the emergence of the 15-M socio-political protest movement in Spain assessed the emotions and beliefs of both demonstrators and those who took no part in the active mobilization. We hypothesized that anger and hope would sequentially mediate the relationship between collective action frames and participation in collective action. Furthermore, to test this premise, we ran two alternative sequential mediation models based on the social identity model of collective action (SIMCA and the encapsulated model of social identity in collective action (EMSICA, but with emotions as mediators between collective action frames and intensity of participation. Both models fit the data well, suggesting the importance of considering multiple causal pathways, and showing that anger and hope sequentially mediate the relation between these frames and involvement in collective action. The results support the crucial role of hope in mobilizing individuals to take part in collective action.

  2. Using action observation to study superior motor performance: A pilot fMRI study

    Directory of Open Access Journals (Sweden)

    CJ eOlsson


    Full Text Available The most efficient way to acquire motor skills may be through physical practice. Nevertheless, it has also been shown that action observation may improve motor performance. The aim of the present pilot study was to examine a potential action observation paradigm used to 1 capture the superior performance of expert athletes and 2 capture the underlying neural mechanisms of successful action observation in relation to task experience. We used functional magnetic resonance imaging (fMRI to measure regional blood flow while presenting videos of a hockey player shooting a puck towards a hockey goal. The videos (a total of 120 where stopped at different time frames with different amount of information provided, creating a paradigm with three different levels of difficulty to decide the fate of a shot. Since this was only a pilot study, we first tested the paradigm behaviorally on 6 elite expert hockey players, 5 intermediate players, and 6 non-hockey playing controls. The results showed that expert hockey players were significantly (p < .05 more accurate on deciding the fate of the action compared to the others. Thus, it appears as if the paradigm can capture superior performance of expert athletes (aim 1. We then tested 3 of the hockey players and 3 of the controls on the same paradigm in the MRI scanner to investigate the underlying neural mechanisms of successful action anticipation. The imaging results showed that when expert hockey players observed and correctly anticipated situations, they recruited motor and temporal regions of the brain. Novices, on the other hand, relied on visual regions during observation and prefrontal regions during action decision. Thus, the results from the imaging data suggest that different networks of the brain are recruited depending on task experience (aim 2. In conclusion, depending on the level of motor skill of the observer, when correctly anticipating actions different neural systems will be recruited.

  3. Biomechanical Analysis of Defensive Cutting Actions During Game Situations: Six Cases in Collegiate Soccer Competitions

    Directory of Open Access Journals (Sweden)

    Sasaki Shogo


    Full Text Available The strengths of interpersonal dyads formed by the attacker and defender in one-on-one situations are crucial for performance in team ball sports such as soccer. The purpose of this study was to analyze the kinematics of one-on-one defensive movements in soccer competitions, and determine the relationships between lower limb kinematics and the center of mass translation during cutting actions. Six defensive scenes in which a player was responding to an offender’s dribble attack were selected for analysis. To reconstruct the three-dimensional kinematics of the players, we used a photogrammetric model-based image-matching technique. The hip and knee kinematics were calculated from the matched skeleton model. In addition, the center of mass height was expressed as a ratio of each participant’s body height. The relationships between the center of mass height and the kinematics were determined by the Pearson’s product-moment correlation coefficient. The normalized center of mass height at initial contact was correlated with the vertical center of mass displacement (r = 0.832, p = 0.040 and hip flexion angle at initial contact (r = −0.823, p = 0.044. This suggests that the lower center of mass at initial contact is an important factor to reduce the downwards vertical center of mass translation during defensive cutting actions, and that this is executed primarily through hip flexion. It is therefore recommended that players land with an adequately flexed hip at initial contact during one-on-one cutting actions to minimize the vertical center of mass excursion.

  4. The "symmetrical turn" in the study of colective action

    Directory of Open Access Journals (Sweden)

    Israel Rodríguez Giralt


    Full Text Available Conceptualising and understanding forms of collective action is one of the historic preoccupations of social thought. Good evidence of this can be found in the long line of disputes and polemics that runs through the history of thought about these social phenomena. It shows the difficulty social sciences have faced, and continue to face, when it comes to defining, explaining and delineating a phenomena as ephemeral and liminal as this one.In this context, I propose that a discussion of the implications an STS focus could have for the analysis of contemporary collective action. The main hypothesis I develop states that the conceptual and methodological baggage that goes with the Actor-Network theory (ANT, and its shaping into what has been called the 'symmetrical turn' in the social sciences, become a fundamental resource for renewing and enriching the analysis of collective action. For this, I will bring together two main contributions: its alternative understanding of social action (to explain the social it is necessary to  leave the exclusive concern with social relations aside and take into account the non-human actors, such as the technical procedures in which they are involved; and its original definition of the “collective” (the collective is basically an aggregate of humans and non-humans, without predefined borders, it is just the relational product created by the constant and precarious commitment between heterogeneous elements. Both contributions, I affirm, allow the opening of an interesting discussion about agency and the possibility of articulating a new theory of collective action that differs from the dominant traditions in that it considers and assumes the heterogeneous and relational character of all social actors, and, as such, it also assumes that all social action is the emergent effect, the interactive product of those hybrid collectives in action. To give an example of the fertility of this approach, I focus on an

  6. Action research in rehabilitation with chronic stroke recovery: A case report with a focus on neural plasticity. (United States)

    Pedersen, Malene; Bundgaard, Tina H; Zeeman, Peter; Jørgensen, Jørgen R; Sørensen, Peter M B; Berro, Hamza M; Larsson, Bodil W


    Chronic stroke patients are primarily referred to general rehabilitation, rather than to specific neurorehabilitation. Currently, there are no Danish clinical guidelines for chronic stroke, but recent research in neuroplasticity has contributed to possible rehabilitation interventions for these patients. The purpose of this project is to describe the use of a specialized neuroplastic approach in combination with an already existing training program. The project is designed as an action research project concerning four participants with chronic stroke. Through ten intervention, a neuroplastic focus has been added to their group training program including daily home training. Participants were tested before and after the intervention with MAS, DGI, 6MWT, SSQLS. All four participants improved their functional levels and their quality of life following the intervention. This report indicates that a specific neuroplastic focus in combination with action research has an impact on the participants with chronic stroke. However, there is still no clarity regarding what type of rehabilitation methods can be considered the most efficacious in promoting neuroplasticity. This case report serves as a pilot project for further studies of how to implement neuroplasticity in physical therapy.

  9. Stretching the limits of visual attention: the case of action video games. (United States)

    Hubert-Wallander, Bjorn; Green, C Shawn; Bavelier, Daphne


    Visual attention is the set of mechanisms by which relevant visual information is selected while irrelevant information is suppressed, thus allowing the observer to function in a world made up of nearly infinite visual information. Recently, those who habitually play video games have been documented to outperform novices in a variety of visual attentional capabilities, including attention in space, in time, and to objects. Training studies have established similar improvements in groups of nongamers given experience playing these video games. Critically, not all video games seem to have such a beneficial effect on attention; it seems that fast-paced, embodied visuo-motor tasks that require divided attention (tasks commonly found in popular action games like Halo) have the greatest effect. At the core of these action video game-induced improvements appears to be a remarkable enhancement in the ability to efficiently deploy endogenous attention. The implications of such an enhancement are relevant to a variety of real-world applications, such as work force training, rehabilitation of clinical populations, and improvement of traditional educational approaches.

  10. The impact of inquiry-based instructional professional development upon instructional practice: An action research study (United States)

    Broom, Frances A.

    This mixed method case study employs action research, conducted over a three month period with 11 elementary math and science practitioners. Inquiry as an instructional practice is a vital component of math and science instruction and STEM teaching. Teachers examined their beliefs and teaching practices with regard to those instructional factors that influence inquiry instruction. Video-taped lessons were compared to a rubric and pre and post questionnaires along with two interviews which informed the study. The results showed that while most beliefs were maintained, teachers implemented inquiry at a more advanced level after examining their teaching and reflecting on ways to increase inquiry practices. Because instructional practices provide only one component of inquiry-based instruction, other components need to be examined in a future study.

The principle of the case-non case study is to compare drug exposure in cases of a studied adverse reaction with that of cases of other reported adverse reactions and called "non cases". Results are presented in the form of a reporting odds ratio (ROR), the interpretation of which makes it possible to identify drug safety signals. This article describes the principle of the case-non case study, the method of calculating the ROR and its confidence interval, the different modalities of analysis and how to interpret its results with regard to the advantages and limitations of this design.

  17. New forms of political action: the case of companies taken over by their employees

    Directory of Open Access Journals (Sweden)

    Ferrari, Liliana Edith


    Full Text Available Framed in Communitarian Social Psychology, this study examines the Argentine experience of worker takeovers. Such takeovers had their origin in the crisis that the country faced in the late 90s. We analyze what the takeover meant to the workers in terms of their subjective identity. Their collective action presents an alternative to the usual triad of rights: to exist, to work, and to receive support. It displays new forms of agency and resistance to unemployment and its negative social labelling. Focussing on two workers' cooperatives, we examine the main changes in individuals' identity, in their organization among themselves, as they try to survive in the market. Finally, we examine points of contact and difference between these workers' struggles and new social movements in their relation to community and State.

  18. Case management roles of clinicians: a research case study. (United States)

    Sterling, Y M; Noto, E C; Bowen, M R


    The purpose of this research multiple case study was to determine case management roles as demonstrated by four clinicians employed at a university medical center. Multiple sources of evidence were used to collect data, including interviews, nonparticipant observations, and chart audits. Case management was defined by the clinicians as a process for delivery of health care at the institution studied. Despite a lack of a uniform framework for case management practice, the clinicians used similar case management components. Chart audits demonstrated deficits and inconsistency in documentation that were supported by interview and observations. It was recommended that exposure to formal case management models and theory could strengthen clinical practice in this area. Additionally, investigation of factors that facilitate and/or impede consistent documentation of interventions and patient outcomes, particularly by CNSs is recommended.

  20. Concentrated photovoltaics, a case study

    Directory of Open Access Journals (Sweden)

    Antonini Piergiorgio


    Full Text Available Concentrated Photovoltaics (CPV, once a niche technology, has now reached the maturity and reliability for large scale power generation. Especially in regions where temperatures are very high, the use of high efficiency triple junction solar cells with concentrating optics allows stable energy yield. Thus CPV can be seen as complementary and not in concurrence with silicon photovoltaics. The state of the art, the advantages and limitations of this technology will be shown. Among the main advantages of CPV is the possibility of a much higher energy supply, when compared to silicon photovoltaics, both comparing CPV and silicon with same area or the same installed power. The use of recycled and recyclable materials allows a more environmentally friendly production. The possibility to couple CPV with desalination facilities, energy storage will be analysed. As an example a case study of a CPV installation in Northern Italy is discussed. Here the use of mature technologies, derived from automotive and lighting sectors resulted in a simple and efficient module.

  1. Case Studies of Environmental Visualization

    Directory of Open Access Journals (Sweden)

    Panagiotis Patlakas


    Full Text Available The performance gap between simulation and reality has been identified as a major challenge to achieving sustainability in the Built Environment. While Post-Occupancy Evaluation (POE surveys are an integral part of better understanding building performance, and thus addressing this issue, the importance of POE remains relatively unacknowledged within the wider Built Environment community. A possible reason that has been highlighted is that POE survey data is not easily understood and utilizable by non-expert stakeholders, including designers. A potential method by which to address this is the visualization method, which has well established benefits for communication of big datasets. This paper presents two case studies where EnViz (short for “Environmental Visualization”, a prototype software application developed for research purposes, was utilized and its effectiveness tested via a range of analysis tasks. The results are discussed and compared with those of previous work that utilized variations of the methods presented here. The paper concludes by presenting the lessons drawn from the five-year period of EnViz, emphasizing the potential of environmental visualization for decision support in environmental design and engineering for the built environment, and suggests directions for future development.

  3. Action semantics modulate action prediction. (United States)

    Springer, Anne; Prinz, Wolfgang


    Previous studies have demonstrated that action prediction involves an internal action simulation that runs time-locked to the real action. The present study replicates and extends these findings by indicating a real-time simulation process (Graf et al., 2007), which can be differentiated from a similarity-based evaluation of internal action representations. Moreover, results showed that action semantics modulate action prediction accuracy. The semantic effect was specified by the processing of action verbs and concrete nouns (Experiment 1) and, more specifically, by the dynamics described by action verbs (Experiment 2) and the speed described by the verbs (e.g., "to catch" vs. "to grasp" vs. "to stretch"; Experiment 3). These results propose a linkage between action simulation and action semantics as two yet unrelated domains, a view that coincides with a recent notion of a close link between motor processes and the understanding of action language.

  7. Experimental study of cyclic action of plasma on tungsten (United States)

    Voronin, A. V.; Aleksandrov, A. E.; Ber, B. Ya.; Brunkov, P. N.; Bormatov, A. A.; Gusev, V. K.; Demina, E. V.; Novokhatskii, A. N.; Pavlov, S. I.; Prusakova, M. D.; Sotnikova, G. Yu.; Yagovkina, M. A.


    We report on experimental results on multiple action of hydrogen, deuterium, and helium plasmas produced by a plasma gun and the Globus-M tokamak on tungsten. The surface temperature in the course of irradiation is measured with a bichromatic pyrometer with a time resolution of ⩾1 μs. The morphology of the surface layer is investigated and X-ray structure analysis of tungsten exposed to multiple radiations by the plasma under various conditions is carried out. A slight decrease in the lattice parameter in the sample subjected to the maximal number of irradiation cycles is detected. It is shown that the morphology of the tungsten surface irradiated by the hydrogen plasma from the gun and by the deuterium plasma from the Globus-M tokamak changes (the structure becomes smoother). The characteristic depth of the layer in which impurities have been accumulated exceeds 0.5 μm. This depth was the largest for the sample exposed to 1000 shots from the gun and 2370 shots from the tokamak. It is shown that the helium jet from the plasma gun makes it possible to simulate the action of helium ions on the International Thermonuclear Experimental Reactor (ITER) diverter, producing a layer of submicrometer particles (bubbles).

  8. Hybrid Risk Management Methodology: A Case Study

    Directory of Open Access Journals (Sweden)

    Jacky Siu-Lun Ting


    Full Text Available Risk management is a decision-making process involving considerations of political, social, economic and engineering factors with relevant risk assessments relating to a potential hazard. In the last decade, a number of risk management tools are introduced and employed to manage and minimize the uncertainty and threats realization to the organizations. However, the focus of these methodologies are different; in which companies need to adopt various risk management principles to visualize a full picture of the organizational risk level. Regarding to this, this paper presents a new approach of risk management that integrates Hierarchical Holographic Modeling (HHM, Enterprise Risk Management (ERM and Business Recovery Planning (BCP for identifying and assessing risks as well as managing the consequences of realized residual risks. To illustrate the procedures of the proposed methodology, a logistic company ABC Limited is chosen to serve as a case study Through applying HHM and ERM to investigate and assess the risk, ABC Limited can be better evaluated the potential risks and then took the responsive actions (e.g. BCP to handle the risks and crisis in near future.

  18. [Instrumental, communicative and strategic actions: a descriptive study of nursing practice according to critical theory]. (United States)

    Rich-Ruiz, Manuel


    According to the literature consulted, the biomedical approach continues dominating the ways in which nurses think, work and inform. In order to study whether this situation also occurs in our context, this research proposes to 1) describe the value or weight nurses give to the different instrumental, strategic and communicative actions, according to Habermas' Theory of the Communicative Action; as well as 2) analyse its possible relationship with the type of unit in which nurses work. It is a descriptive study including 89 nurses, conducted in medical, surgical and onco-haematological hospital wards in the Hospital Reina Sofia of Cordoba. For the data collection, a questionnaire was created specifically for the study, made up of 4 instrumental actions, 4 strategic actions and 4 communicative actions that were scored 1-5 according to their value or importance. The questionnaire was self-administered and collected after one week. The instrumental actions obtain the highest scores in the area of thoughts (19.49) and practice (18.9), followed by the communicative actions. Nevertheless, the strategic actions exceeded the communicative actions in the record (17.27 vs 14.49). Only in the onco-haematology units, communicative actions maintained high scores (17.26). The results from the present study emphasise the hegemony of the biomedical model, represented by instrumental and strategic actions, and draw a difficult situation for the communicative action, which has to find its place in the professional speech.

  20. Phencyclidine Intoxication Case Series Study. (United States)

    Dominici, Paul; Kopec, Kathryn; Manur, Rashmi; Khalid, Abdullah; Damiron, Kathia; Rowden, Adam


    Phencyclidine (PCP) is a synthetic compound derived from piperidine and used as an anesthetic and hallucinogenic. Little has been recently published regarding the clinical presentation of PCP intoxication. PCP use as a recreational drug is resurging. Our objective was to describe clinical findings in patients presenting to the emergency department (ED) under the influence of PCP. This was a case series study conducted at a tertiary care center with an annual census of 100,000 patients/year. Emergency physicians, residents, physician assistants, and research assistants identified patients with possible PCP intoxication. Self-reported PCP use, report by bystanders or Emergency Medical Services (EMS) staff, was used in this process. A structured data collection form was completed, documenting both clinical and behavioral events observed by the treating team during the ED visit. We collected data on 219 patients; 184 were analyzed; two patients were excluded secondary to incomplete data. The mean age of patients was 32.5 years (±7 years) with 65.2 % being males. PCP use was self-reported by 60.3 % of patients. Of the 184 patients, 153 (83.1 %) received a urine drug screen (UDS); 152 (98.7 %) were positive for PCP. On arrival, 78.3 % of patients were awake and alert, and 51.6 % were oriented to self, time/date, and place. Mean physiological parameters were the following: heart rate 101.1 bpm (±24.3), RR 18.9 bpm (±3.4), BP 146.3 (±19.4)/86.3 (±14.0) mmHg, 36.9° C (±0.5), and pulse oximetry 98.2 % (±1.9). Clinical findings were the following: retrograde amnesia in 46 (25 %), horizontal nystagmus in 118 (64.1 %), vertical nystagmus in 90 (48.9 %), hypertension in 87 (47.3 %), and agitation in 71 (38.6 %). Concomitant use of at least one other substance was reported by 99 (53.8 %) patients. The mean length of stay in the ED for all subjects was 261.1 (±172.8) minutes. Final disposition for 152 (82.6 %) patients was to home. Of the 184 patients, 14 (7.6 %) required

  1. How action selection influences the sense of agency: An ERP study. (United States)

    Sidarus, Nura; Vuorre, Matti; Haggard, Patrick


    Sense of agency (SoA) refers to the feeling that we are in control of our actions and, through them, of events in the outside world. One influential view claims that the SoA depends on retrospectively matching the expected and actual outcomes of action. However, recent studies have revealed an additional, prospective component to SoA, driven by action selection processes. We used event-related potentials (ERPs) to clarify the neural mechanisms underlying prospective agency. Subliminal priming was used to manipulate the fluency of selecting a left or right hand action in response to a supraliminal target. These actions were followed by one of several coloured circles, after a variable delay. Participants then rated their degree of control over this visual outcome. Incompatible priming impaired action selection, and reduced sense of agency over action outcomes, relative to compatible priming. More negative ERPs immediately after the action, linked to post-decisional action monitoring, were associated with reduced agency ratings over action outcomes. Additionally, feedback-related negativity evoked by the outcome was also associated with reduced agency ratings. These ERP components may reflect brain processes underlying prospective and retrospective components of sense of agency respectively. Copyright © 2017 The Authors. Published by Elsevier Inc.

  2. Action research studies in the intensive care setting: a systematic review. (United States)

    Soh, K L; Davidson, P M; Leslie, G; Bin Abdul Rahman, Aisai


    To review published studies using action research in the intensive care unit (ICU) in order to provide an intervention framework to improve clinical outcomes. Systematic review. Searches of the electronic databases: Cumulative Index of Nursing and Allied Health Literature (CINAHL); Scopus, Medline, Embase, PsycINFO, and the World Wide Web were undertaken using MeSH key words including: 'action research'; 'health care research', 'health services evaluation'; 'intensive care unit'. Reference lists of retrieved articles was also undertaken to identify further articles. All studies were reviewed by two authors using a critical appraisal tool. The search strategy generated 195 articles. Only 21 studies projects were identified using action research in the ICU. The majority of studies were conducted in the United Kingdom. The participants in the action research studies ranged from 6 to 253. Predominately studies using action research involved nurses in collaboration with patients and family and other health care practitioners to address identified problems in the ICU. Based on this review it appears that action research is a promising methodological approach to address clinical practice improvement in the ICU. Studies retrieved focussed primarily on process and formative evaluation but not on clinical outcomes. There is a need to incorporate outcome assessment in action research in the ICU to increase the framework of action research to improve clinical outcomes. Copyright © 2010 Elsevier Ltd.

The article described the process of the teacher’s reprofessionalization and presented the situations which the teacher encountered, too. The teacher reformed

  4. Target-distractor synchrony affects performance in a novel motor task for studying action selection (United States)

    Paine, Phillip J.; Heaton, Timothy J.; Anderson, Sean; Da Lio, Mauro; Gurney, Kevin


    The study of action selection in humans can present challenges of task design since our actions are usually defined by many degrees of freedom and therefore occupy a large action-space. While saccadic eye-movement offers a more constrained paradigm for investigating action selection, the study of reach-and-grasp in upper limbs has often been defined by more complex scenarios, not easily interpretable in terms of such selection. Here we present a novel motor behaviour task which addresses this by limiting the action space to a single degree of freedom in which subjects have to track (using a stylus) a vertical coloured target line displayed on a tablet computer, whilst ignoring a similarly oriented distractor line in a different colour. We ran this task with 55 subjects and showed that, in agreement with previous studies, the presence of the distractor generally increases the movement latency and directional error rate. Further, we used two distractor conditions according to whether the distractor’s location changes asynchronously or synchronously with the location of the target. We found that the asynchronous distractor yielded poorer performance than its synchronous counterpart, with significantly higher movement latencies and higher error rates. We interpret these results in an action selection framework with two actions (move left or right) and competing ‘action requests’ offered by the target and distractor. As such, the results provide insights into action selection performance in humans and supply data for directly constraining future computational models therein. PMID:28475622

    Energy Technology Data Exchange (ETDEWEB)

    Wagner, Fred [Energetics Incorporated, Columbia, MD (United States); Roberts, Dave [Vermont Energy Investment Corporation (VEIC), Burlington, VT (United States); Francfort, Jim [Idaho National Lab. (INL), Idaho Falls, ID (United States); White, Sera [Idaho National Lab. (INL), Idaho Falls, ID (United States)


    Currently in the United States, the heavy majority of plug-in electric vehicle (PEV) sales have been in highly conducive, selected, metropolitan areas; opposed to more broad distribution across the country. The U.S. Department of Energy’s EV Everywhere Grand Challenge is looking carefully at the barriers and opportunities that exist to enable small and midsize communities to partake in the PEV market and benefit from the economic and environmental advantages of PEVs. In order to gain insight into these challenges and barriers, DOE selected a success story (i.e., Drive Electric Vermont) as the subject of this case study, as the state of Vermont is tied with Detroit, Michigan in having the highest percentage of 2014 (most recent complete data) PEV registrations for cold weather U.S. cities and has seen more than a sixfold increase in charging stations over the last three years. The overall objective of this case study was to use the lessons learned from Drive Electric Vermont to determine what activities are most effective at encouraging acquisitions of PEVs and deployment of charging infrastructure in small to midsize communities, prioritizing and sequencing their implementation, identifying robust means for extrapolation, and applying this understanding to other small to midsize communities across the nation. The Drive Electric Vermont Program was formed in 2012 with a goal of increasing the use of electrified transportation in Vermont through policy development, education and outreach, and infrastructure development. The Drive Electric Vermont Program can be broadly broken into four components: (1) strategic planning/leadership, (2) stakeholder/partnership development, (3) education and outreach, and (4) incentives. The early phases of the program focused heavily on strategic planning, and stakeholder and partnership development, followed by a transition to education and outreach activities, charging infrastructure development, and grant and incentive programs

    Hazel Taylor


    Full Text Available Systems analysis students seldom experience the practical difficulties of the initial investigation into a client’s requirements. They get little chance to practice the skills they need to investigate complex and confused problem situations, or to appreciate the wider organizational issues that can impact on a situation. This teaching case is designed to give students the opportunity to practice and apply investigation skills and to challenge them to consider the wider work environment when considering possible solutions to a problem situation. The case is conducted as a role-play, with students acting as systems analysts and teaching staff role-playing the clients. The students develop a report analyzing the client’s situation based on the issues that arise during the interviews. Feed-back sessions focus on discussing how well the students applied various interviewing strategies previously covered in lectures, and on the wider organizational problems that could impact proposed information system solutions.

We suggest, in line with a previous case study, an alternative account in the framework of (non abstractive) episodic models of memory.

  13. The early development of object knowledge: A study of infants' visual anticipations during action observation

  17. Case Studies in Neurocritical Care. (United States)

    Sakusic, Amra; Rabinstein, Alejandro A


    The practice of neurocritical care encompasses multiple acute neurologic and neurosurgical diseases and requires detailed knowledge of neurology and critical care. This article presents 5 cases that illustrate just some of the conditions encountered in the daily practice of neurocritical care and exemplify some of the common diagnostic, therapeutic, and prognostic challenges facing the neurointensivist. Life-threatening medical complications after severe acute ischemic stroke, seizures and extreme agitation from autoimmune encephalitis, refractory seizures after subdural hemorrhage, neurologic and systemic complications related to aneurysmal subarachnoid hemorrhage, and status epilepticus after cardiac arrest are discussed in this article.

  18. Social cognition in simple action coordination: A case for direct perception. (United States)

    Abramova, Ekaterina; Slors, Marc


    In this paper we sketch the outlines of an account of the kind of social cognition involved in simple action coordination that is based on direct social perception (DSP) rather than recursive mindreading. While we recognize the viability of a mindreading-based account such as e.g. Michael Tomasello's, we present an alternative DSP account that (i) explains simple action coordination in a less cognitively demanding manner, (ii) is better able to explain flexibility and strategy-switching in coordination and crucially (iii) allows for formal modeling. This account of action coordination is based on the notion of an agent's field of affordances. Coordination ensues, we argue, when, given a shared intention, the actions of and/or affordances for one agent shape the field of affordances for another agent. This a form of social perception since in particular perceiving affordances for another person involves seeing that person as an agent. It is a form of social perception since it involves perceiving affordances for another person and registering how another person's actions influence one's own perceived field of affordances.

  20. The case for integrating grounded theory and participatory action research: empowering clients to inform professional practice. (United States)

    Teram, Eli; Schachter, Candice L; Stalker, Carol A


    Grounded theory and participatory action research methods are distinct approaches to qualitative inquiry. Although grounded theory has been conceptualized in constructivist terms, it has elements of positivist thinking with an image of neutral search for objective truth through rigorous data collection and analysis. Participatory action research is based on a critique of this image and calls for more inclusive research processes. It questions the possibility of objective social sciences and aspires to engage people actively in all stages of generating knowledge. The authors applied both approaches in a project designed to explore the experiences of female survivors of childhood sexual abuse with physical therapy and subsequently develop a handbook on sensitive practice for clinicians that takes into consideration the needs and perspectives of these clients. Building on this experience, they argue that the integration of grounded theory and participatory action research can empower clients to inform professional practice.

  1. Using the unfolding case study in midwifery education. (United States)

    Carr, Katherine Camacho


    One of the challenges in teaching clinicians is helping health care provider students, including midwives, develop the critical thinking and clinical decision-making skills needed for various situations encountered in practice. Health care provider students need to master the required core knowledge and skills but also need to assess, analyze, judge, decide on action, act, and evaluate their actions. Lecture-heavy classroom teaching, which is usually delivered separately from clinical experiences in health care education, focuses on knowledge acquisition, often leaving knowledge application to trial and error. Case studies are commonly used by faculty with a problem-based learning approach, which is more analytic but sometimes static. The unfolding case study presents students with a patient scenario that changes over time and allows for discussion; lecture points as needed; and decision making as the situation or condition changes, reflecting what happens in real-life clinical practice. The use of the unfolding case study moves health care provider education from fact-based lecturing to situation-based discussion and decision making as a person's condition or situation changes. Use of the unfolding case facilitates collaborative learning, covers necessary content, and assists students to think beyond the facts and use their clinical imagination. Unfolding case studies require students to begin to grasp the nature of a clinical situation and adjust interventions as the clinical situation unfolds. Steps in developing and using an unfolding case study for midwifery students are presented, including 2 examples. This article is part of a special series of articles that address midwifery innovations in clinical practice, education, interprofessional collaboration, health policy, and global health. © 2015 by the American College of Nurse-Midwives.

  2. Treating organic abulia with bromocriptine and lisuride: four case studies. (United States)

    Barrett, K


    Abulia refers to an impairment of will, or the inability to initiate behaviour and action. There are reports of successful treatment of akinetic mutism, the most severe form of abulia, with bromocriptine. Four case studies are presented describing the successful treatment of abulia at a lesser severity than akinetic mutism with bromocriptine. Abulia was caused by brain damage due to alcohol in two cases, Wilson's disease and basal ganglia infarct in one each. Maximum bromocriptine dose varied from 25-70 mg. All improved considerably. Withdrawal or reduction of medication in three produced deterioration. The prescription of a neuroleptic drug had a similar effect in the fourth. One patient with a previous history developed a depressive relapse and so the drug was withdrawn and lisuride introduced. This produced a similar improvement. These cases highlight the value of identifying the syndrome of organic abulia and suggest that dopamine agonists may have a place in its treatment, though controlled studies are needed. PMID:1940945

  3. Zimbabwe's national AIDS levy: A case study. (United States)

    Bhat, Nisha; Kilmarx, Peter H; Dube, Freeman; Manenji, Albert; Dube, Medelina; Magure, Tapuwa


    We conducted a case study of the Zimbabwe National AIDS Trust Fund ('AIDS Levy') as an approach to domestic government financing of the response to HIV and AIDS. Data came from three sources: a literature review, including a search for grey literature, review of government documents from the Zimbabwe National AIDS Council (NAC), and key informant interviews with representatives of the Zimbabwean government, civil society and international organizations. The literature search yielded 139 sources, and 20 key informants were interviewed. Established by legislation in 1999, the AIDS Levy entails a 3% income tax for individuals and 3% tax on profits of employers and trusts (which excluded the mining industry until 2015). It is managed by the parastatal NAC through a decentralized structure of AIDS Action Committees. Revenues increased from inception to 2006 through 2008, a period of economic instability and hyperinflation. Following dollarization in 2009, annual revenues continued to increase, reaching US$38.6 million in 2014. By policy, at least 50% of funds are used for purchase of antiretroviral medications. Other spending includes administration and capital costs, HIV prevention, and monitoring and evaluation. Several financial controls and auditing systems are in place. Key informants perceived the AIDS Levy as a 'homegrown' solution that provided country ownership and reduced dependence on donor funding, but called for further increased transparency, accountability, and reduced administrative costs, as well as recommended changes to increase revenue. The Zimbabwe AIDS Levy has generated substantial resources, recently over US$35 million per year, and signals an important commitment by Zimbabweans, which may have helped attract other donor resources. Many key informants considered the Zimbabwe AIDS Levy to be a best practice for other countries to follow.

  5. Ethical issues in case study publication: "making our case(s)" ethically. (United States)

    McCurdy, David B; Fitchett, George


    As chaplains develop richly detailed case studies for publication, ethical questions about case study construction and publication are emerging. Concerns about seeking patients' permission to publish material about them suggest additional questions and raise broad confidentiality and privacy issues. Confidentiality-related practices in health care and psychotherapy provide the most extensive guidance for chaplains, but healthcare chaplaincy has roots in religious and professional traditions with distinct notions of confidentiality that deserve consideration. Single case studies do not appear to be "research" requiring informed consent, yet their publication exposes patients to some risk of harm. Obtaining the patient's/"case study subject's" permission to publish, disguising non-essential information, and allowing the patient to review the case study can mitigate the risks. Striking a balance between protecting patients and providing sufficient detail to make case studies useful is a central ethical challenge of case study publication.

  9. Singing well-becoming: Student musical therapy case studies

    Directory of Open Access Journals (Sweden)

    Tim Murphey


    Full Text Available Much research supports the everyday therapeutic and deeper socialneurophysiological influence of singing songs alone and in groups (Austin, 2008; Cozolino, 2013; Sacks, 2007. This study looks at what happens when Japanese students teach short English affirmation songlet-routines to others out of the classroom (clandestine folk music therapy. I investigate 155 student-conducted musical case studies from 7 semester-long classes (18 to 29 students per class over a 4-year period. The assignments, their in-class training, and their results are introduced, with examples directly from their case studies. Each class published their own booklet of case studies (a class publication, available to readers online for research replication and modeling. Results show that most primary participants enjoyed spreading these positive songlets as they became “well-becoming agents of change” in their own social networks. “Well-becoming” emphasizes an agentive action or activity that creates better well-being in others, an action such as the sharing or teaching of a songlet. The qualitative data reveals a number of types of well-becoming such as social and familial bonding, meaning-making, teaching-rushes, and experiencing embodied cognition. The project also stimulated wider network dissemination of these well-becoming possibilities and pedagogical insights.

  10. Action of anti-TNF-α drugs on the progression of Alzheimer's disease: A case report

    Directory of Open Access Journals (Sweden)

    Carlos Henrique Ferreira Camargo

    Full Text Available The aim of this study was to describe a clinical case of a patient with Alzheimer's disease (AD in use of an anti-TNF-α agent for rheumatoid arthritis (RA. The patient reported is an 81-year-old Caucasian man and retired teacher, diagnosed with RA in 2008 and AD in 2011. Treatment with donepezil was started in 2011 and the use of etanercept introduced in 2012. He was previously treated with adalimumab in 2010 for 18 months. In 2013, the subject was engaged in a clinical trial to assess a complementary non-pharmacological approach for AD, presenting significant cognitive improvement during the follow-up period. We propose the hypothesis of a synergistic effect of anti-TNF-α medication used for the treatment of RA as the cause of the improvement in cognitive response observed. These findings could suggest a possible use of this drug class in the therapeutic management of AD.

  11. Leishmaniasis in dogs: Case study

    Directory of Open Access Journals (Sweden)

    Aleksić Jelena


    Full Text Available The paper presents a case of leishmaniasis in a 2.5-month-old dog imported from France. The clinical examination established a generally poor state of health, expressed cachexia, atrophy of the temporal musculature, weakness of movement, as well as abnormally long and brittle nails. There was also hyperkeratosis of the nose tip and paws. A histological examination of biopsy sections of the altered skin parts showed inflammatory changes in the area of the dermis, together with infiltration of macrophages and a smaller number of lymphocytes, plasmocytes and neutrophil granulocytes in the area around the sebaceous glands and hair follicles. The determined changes correspond to superficial dermatitis. Edema followed by partial degeneration of connective-tissue fibers is observed in connective tissue. A smaller number of intracellular parasitic forms was established in mononuclear cells. A smaller number of oval amastigotes with round dark red nucleis were observed in sections stained using the Gimza method in the cytoplasm of macrophages located in the dermis, but also extracellularly. It was concluded that the dog was diseased with leishmaniasis on the grounds of the clinical picture and the microscopic findings.

  20. Sentence production in rehabilitation of agrammatism: A case study (United States)

    Silagi, Marcela Lima; Hirata, Fernanda Naito; de Mendonça, Lúcia Iracema Zanotto


    Agrammatism is characterized by morphosyntactic deficits in production of sentences. Studies dealing with the treatment of these deficits are scarce and their results controversial. The present study describes the rehabilitation of a case diagnosed as chronic Broca's aphasia, with agrammatism, using a method directed to sentence structural deficits. The method aims to expand the grammatical repertoire by training production of sentences with support from contexts that stimulate actions and dialogues. The patient showed positive results on all types of sentences trained and generalized the gains to spontaneous speech. However, these benefits were not sustained in the long term. PMID:29213917

    Kinney, L; Wilson, T.; Lewis, G. [Synertech Systems Corp. (United States); MacDonald, M. [Oak Ridge National Lab., TN (United States)


    The multifamily case studies that are the subject of this report were conducted to provide a better understanding of the approach taken by program operators in weatherizing large buildings. Because of significant variations in building construction and energy systems across the country, five states were selected based on their high level of multifamily weatherization. This report summarizes findings from case studies conducted by multifamily weatherization operations in five cities. The case studies were conducted between January and November 1994. Each of the case studies involved extensive interviews with the staff of weatherization subgrantees conducting multifamily weatherization, the inspection of 4 to 12 buildings weatherized between 1991 and 1993, and the analysis of savings and costs. The case studies focused on innovative techniques which appear to work well.

  4. An fMRI study of perception and action in deaf signers. (United States)

    Okada, Kayoko; Rogalsky, Corianne; O'Grady, Lucinda; Hanaumi, Leila; Bellugi, Ursula; Corina, David; Hickok, Gregory


    Since the discovery of mirror neurons, there has been a great deal of interest in understanding the relationship between perception and action, and the role of the human mirror system in language comprehension and production. Two questions have dominated research. One concerns the role of Broca's area in speech perception. The other concerns the role of the motor system more broadly in understanding action-related language. The current study investigates both of these questions in a way that bridges research on language with research on manual actions. We studied the neural basis of observing and executing American Sign Language (ASL) object and action signs. In an fMRI experiment, deaf signers produced signs depicting actions and objects as well as observed/comprehended signs of actions and objects. Different patterns of activation were found for observation and execution although with overlap in Broca's area, providing prima facie support for the claim that the motor system participates in language perception. In contrast, we found no evidence that action related signs differentially involved the motor system compared to object related signs. These findings are discussed in the context of lesion studies of sign language execution and observation. In this broader context, we conclude that the activation in Broca's area during ASL observation is not causally related to sign language understanding. Copyright © 2016 Elsevier Ltd.

  5. Theoretical pluralism in psychoanalytic case studies (United States)

    Willemsen, Jochem; Cornelis, Shana; Geerardyn, Filip M.; Desmet, Mattias; Meganck, Reitske; Inslegers, Ruth; Cauwe, Joachim M. B. D.


    The aim of this study is to provide an overview of the scientific activity of different psychoanalytic schools of thought in terms of the content and production of case studies published on ISI Web of Knowledge. Between March 2013 and November 2013, we contacted all case study authors included in the online archive of psychoanalytic and psychodynamic case studies ( to inquire about their psychoanalytic orientation during their work with the patient. The response rate for this study was 45%. It appears that the two oldest psychoanalytic schools, Object-relations psychoanalysis and Ego psychology or “Classical psychoanalysis” dominate the literature of published case studies. However, most authors stated that they feel attached to two or more psychoanalytic schools of thought. This confirms that the theoretical pluralism in psychoanalysis stretches to the field of single case studies. The single case studies of each psychoanalytic school are described separately in terms of methodology, patient, therapist, or treatment features. We conclude that published case studies features are fairly similar across different psychoanalytic schools. The results of this study are not representative of all psychoanalytic schools, as some do not publish their work in ISI ranked journals. PMID:26483725

  8. Case Studies Approach in Tourism Destination Branding Research

    Directory of Open Access Journals (Sweden)

    Adeyinka-Ojo S.F.


    Full Text Available A review of literature indicates that there are different types of qualitative research methods such as action research, content analysis, ethnography, grounded theory, historical analysis, phenomenology and case study. However, which approach is to be used depends on several factors such as the nature and objectives of the research. The aim of this paper is to focus on the research methodology aspects of applying case study as a research approach and its relevance in tourism destination branding research specifically on a single case study (SCS context. There are arguments that the SCS is a weak research strategy. Some of the potentials or shortcomings highlighted in the literature include the primitive nature of SCS, flexibility of sample technique, data collection method and data analysis. Others include lack of rigour, reliability, validity, credibility of findings and generalisation. This paper has adopted content analysis of the literature on tourism destination branding. Findings indicate that the quality of SCS can be verified using specific case study tactics for four design tests such as validity (construct, internal and external; and reliability using the case study protocol. Theoretical implication suggests that SCS is an empirical enquiry use to understand complex phenomena and favoured by practitioners.

  11. Actions to promote energy efficient electric motors. Motors study group

    Energy Technology Data Exchange (ETDEWEB)

    Almeida, A.T. de [Coimbra Univ. (PT). Inst. of Systems and Robotics (ISR)


    Motor electricity consumption is influenced by many factors including: motor efficiency, motor speed controls, power supply quality, harmonics, systems oversizing, distribution network, mechanical transmission system, maintenance practices, load management and cycling, and the efficiency of the end-use device (e.g. fan, pump, etc.). Due to their importance, an overview of these factors is presented in this report. This study also describes the electricity use in the industrial and tertiary sectors and the electricity consumption associated with the different types of electric motors systems in the Member States of the European Union, as well as estimated future evolution until 2010. The studies for individual countries were carried out by the different partners of the motors study group at a previous stage. The study has found that there is a lack of accurate information about the motor electricity consumption, installed motor capacity and the motor market in almost all the European Union countries and only some general statistical sources are available. There is little field data, which is mainly available in Denmark, France, Italy and the Netherlands. Due to this lack of primary information, some common assumptions were made, based on the experience of the members of the study group. This lack of end-use characterisation data shows the need for improvement from the point of view of current knowledge. It is therefore recommended that further research is undertaken to arrive at more accurate figures. These could be the basis for a better understanding for motor use in practice and - as a consequence - for a more precise appraisal of potentials and barriers to energy efficiency. (orig.)

  12. Policing, collective action and social movement theory: the case of the Northern Ireland civil rights campaign. (United States)

    Ellison, G; Martin, G


    In this paper we examine the relationship between social movements and the police through an analysis of the Civil Rights Movement (CRM) which emerged in the late 1960s in Northern Ireland. Following della Porta (1995) and Melucci (1996) we argue that the way in which episodes of collective action are policed can affect profoundly both levels of mobilization and the orientation of social movements. We also submit that the symbolic and representational dimensions of policing can be a significant trigger in the stimulation of identification processes and collective action. The paper concludes by questioning some of the assumptions contained within social movement theory, and their applicability to divided societies such as Northern Ireland.

  14. Perceptions of Plagiarism by STEM Graduate Students: A Case Study. (United States)

    Leonard, Michelle; Schwieder, David; Buhler, Amy; Bennett, Denise Beaubien; Royster, Melody


    Issues of academic integrity, specifically knowledge of, perceptions and attitudes toward plagiarism, are well documented in post-secondary settings using case studies for specific courses, recording discourse with focus groups, analyzing cross-cultural education philosophies, and reviewing the current literature. In this paper, the authors examine the perceptions of graduate students in science, technology, engineering, and mathematics (STEM) disciplines at the University of Florida regarding misconduct and integrity issues. Results revealed students' perceptions of the definition and seriousness of potential academic misconduct, knowledge of institutional procedures, and views on faculty actions, all with a focus on divergences between U.S. and internationally-educated students. The open-ended questions provide anecdotal evidence to highlight personal experiences, positive and negative, aimed at the faculty, international students and undergraduates. Combined, these findings outline an important part of the campus academic integrity culture at a major American university. Recommendations for local actions also are discussed.

  15. Multilateral, regional, and national determinants of policy adoption: the case of HIV/AIDS legislative action. (United States)

    Clark, Benjamin Y


    This article examines the global legislative response to the HIV/AIDS epidemic with a particular focus on how policies were diffused internationally or regionally, or facilitated internally. This article uses event history analysis combined with multinomial logit regression to model the legislative response of 133 countries. First, the results demonstrate that the WHO positively influenced the likelihood of a legislative response. Second, the article demonstrates that development bank aid helped to spur earlier legislative action. Third, the results demonstrate that developed countries acted earlier than developing countries. And finally, the onset and severity of the HIV/AIDS epidemic was a significant influence on the legislative response. Multilateral organizations have a positive influence in global policy diffusion through informational advocacy, technical assistance, and financial aid. It is also clear that internal stressors play key roles in legislative action seen clearly through earlier action being taken in countries where the shock of the onset of HIV/AIDS occurred earlier and earlier responses taken where the epidemic was more severe.

  17. Associative Visual Agnosia: A Case Study

    Directory of Open Access Journals (Sweden)

    A. Charnallet


    Full Text Available We report a case of massive associative visual agnosia. In the light of current theories of identification and semantic knowledge organization, a deficit involving both levels of structural description system and visual semantics must be assumed to explain the case. We suggest, in line with a previous case study [1], an alternative account in the framework of (non abstractive episodic models of memory [4].

  18. Case Study Methodology and Homelessness Research

    Directory of Open Access Journals (Sweden)

    Jill Pable


    Full Text Available This paper describes the potential suitability of case study methodology for inquiry with the homeless population. It references a research study that uses case study research method to build theory. This study's topic is the lived experience of destitute individuals who reside in homeless shelters, and explores the homeless shelter built environment's potential influence on resident satisfaction and recovery. Case study methodology may be appropriate because it explores real-life contextual issues that characterize homelessness and can also accommodate the wide range of homeless person demographics that make this group difficult to study in a generalized fashion. Further, case study method accommodates the need within research in this area to understand individualized treatments as a potential solution for homelessness.

  19. Action-skilled observation: Issues for the study of sport expertise and the brain. (United States)

    Karlinsky, April; Zentgraf, Karen; Hodges, Nicola J


    With a growing body of research devoted to uncovering regions of the brain implicated in action observation following various action-related experiences, including sport, we ask what we know from this research, and what we still need to know, as it pertains to sport and the brain. To do this, we review and integrate knowledge garnered from developmental work, short-term motor learning studies, and most significantly sport athletes across varying skill levels. We consider various neurophysiological methods, including TMS, fMRI, and EEG, which have been used to help uncover brain regions involved in action-skilled observation. We are particularly interested in how these processes are related to action prediction and the detection of deceptive actions among athlete groups. This research is considered within broad theoretical frameworks related to action-simulation and prediction, although our main focus is on the brain regions that have been implicated in skilled action observation and the implications of this research for knowledge and further study of sport expertise. © 2017 Elsevier B.V.

  1. Arcturus stream : A case study (United States)

    Ramya, P.; Reddy, Bacham Eswar

    Stellar streams are a group of gravitationally unbound stars which share same kinematic properties, and hence form coherent structures in the velocity space. Their origin is not clear. The concept of stellar streams or moving groups was introduced much early (Eggen 1958) and were thought as dispersed cluster remnants retaining the original kinematics. Subsequently, studies suggested that these are debris of accreted satellite galaxy in the Milkyway and belong to an old stellar population in the solar neighborhood. Kinematic studies reveal that the stream member stars are old and belong to thick disk of the Galaxy. Satellite acceretion scenario is one front runner proposal for the thick disk formation in the Galactic disk. In this study, we have explored one of the streams, known as Arcturus stream, through high resolution spectroscopy. Preliminary abundance results for a sample of Arcturus stream are obtained and compared with groups of stars that belong to thick disk and dwarf spheroidals. Alpha elements, that are known to be produced mainly in the massive but short lived SNII, seem to be enhanced relative to Fe, a dominant product in long lived SNIa. This suggests that the Arcturus stream stars are old and are mostly produced in the era where SNII was predominant. Abundance results are very similar to the results of Galactic thick disk, which is a distinct component in the disk, both kinematically and chemically. It seems Arcturus is a subgroup within the thick disk but to establish whether the group is distinct from the thick disk, we have to determine differential age estimate for a sample of thick disk and Arcturus stars at the overlapping [Fe/H].

  2. The cerebellum in action: a simulation and robotics study. (United States)

    Hofstötter, Constanze; Mintz, Matti; Verschure, Paul F M J


    The control or prediction of the precise timing of events are central aspects of the many tasks assigned to the cerebellum. Despite much detailed knowledge of its physiology and anatomy, it remains unclear how the cerebellar circuitry can achieve such an adaptive timing function. We present a computational model pursuing this question for one extensively studied type of cerebellar-mediated learning: the classical conditioning of discrete motor responses. This model combines multiple current assumptions on the function of the cerebellar circuitry and was used to investigate whether plasticity in the cerebellar cortex alone can mediate adaptive conditioned response timing. In particular, we studied the effect of changes in the strength of the synapses formed between parallel fibres and Purkinje cells under the control of a negative feedback loop formed between inferior olive, cerebellar cortex and cerebellar deep nuclei. The learning performance of the model was evaluated at the circuit level in simulated conditioning experiments as well as at the behavioural level using a mobile robot. We demonstrate that the model supports adaptively timed responses under real-world conditions. Thus, in contrast to many other models that have focused on cerebellar-mediated conditioning, we investigated whether and how the suggested underlying mechanisms could give rise to behavioural phenomena.

    Full Text Available An online community of practice (OCoP is a group of people, who are brought together by a shared interest and with the aim of deepening their understanding of an area of knowledge through regular interactions facilitated by computer mediated communication (CMC tools. An OCoP potentially provides teachers with those elements of effective professional development (PD, cited in the literature, such as; collaboration, opportunities for mentoring, and sustainability over time. In this sense, OCoPs can be considered as a viable alternative for teacher PD. If OCoPs are to become an alternative approach to teacher PD then it is important to understand what factors affect teachers’ participation in such communities. Therefore, through the case of Webheads in Action (WiA OCoP, this study aimed to identify what factors contribute towards creating successful OCoPs. Members’ interactions in WiA’s public group page were collated over a period of nine months and interviews with 24 members of the community (4 core, 9 active, 11 peripheral were used to gather the data. Two major themes emerged in relation to factors affecting members’ participation in this OCoP. The first one was identified as the creation of a sense of belonging to the community which was achieved through various means such as having an initiation process and fostering trust and an inclusive community environment through community norms. The second was dynamism inherent in the community which manifested itself as new topics that kept members interested and participating, and a flow of continuous member recruitment to the community. In conclusion, this study highlighted the importance of the socio-affective dimension for designing and sustaining OCoPs.

  6. Case study in psychobiographical ethics. (United States)

    Ponterotto, Joseph G


    This article addresses ethical issues relative to the conduct and reporting of psychobiographical research. The author's recent psychobiographical study of World Chess Champion Bobby Fischer (1943-2008) is used to illustrate particular ethical challenges and responses in six areas: (1) institutional review board (IRB) evaluation and informed consent; (2) balancing objective research with respect for psychobiographical subject; (3) inviting subject or next-of-kin to read and comment on working drafts of psychobiography; (4) reporting never-before-revealed sensitive information on a subject; (5) role of interdisciplinary consultation in conducting psychobiography; and (6) the value and cautions of including psychological diagnoses as part of the psychological profile. A "bill of rights and responsibilities" for the psychobiographer is introduced as a stimulus for ongoing discussion and empirical research on ethical practice in psychobiography.

  7. Lights, Camera, Action ... and Cooling - The case for centralized low carbon energy at Fox Studios

    Energy Technology Data Exchange (ETDEWEB)

    Robinson, Alastair [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States); Regnier, Cindy [Lawrence Berkeley National Lab. (LBNL), Berkeley, CA (United States)


    Fox Studios partnered with the U.S. Department of Energy (DOE) to develop and implement solutions to retrofit two production stages and one of its central cooling plants, to reduce energy consumption by at least 30% as part of DOE’s Commercial Building Partnerships (CBP) Program. Although this case study reports expected savings arising from proposed design recommendations for a unique building type and the unusual load characteristics associated with its use, the EEMs implemented for the central plant are applicable to any large campus, office and higher education facility. The intent is that by making the energy-efficiency measures (EEMs) set that were assessed as cost-effective from this project applicable to a larger number of buildings on the campus Fox Studios will be able to implement an integrated campus-wide energy strategy for the long term. The significant challenges for this project in the design phase included identifying how to assess and analyze multiple system types, develop a coherent strategy for assessment and analysis, implement the measurement and verification activities to collect the appropriate data (in terms of capturing ‘normal’ operating characteristics and granularity) and determine the best approach to providing cooling to the site buildings based on the nature of existing systems and the expected improvement in energy performance of the central cooling plant. The analytical framework adopted provides a blueprint for similar projects at other large commercial building campuses.

  13. A Unique Case of Intraabdominal Polyorchidism: A Case Study

    Directory of Open Access Journals (Sweden)

    Javier Otero


    Full Text Available Background. Polyorchidism, alternatively supernumerary testes (SNT, is a condition where an individual is born with more than two testicles. This congenital anomaly is quite rare and the literature has described various presentations. Questions/Purposes. To our knowledge, this presentation of polyorchidism has yet to be described in the literature. The goal of this case study is to add to the pediatric, general, and urologic surgery’s body of knowledge of the subject matter. Case Study. A nine-month-old boy was admitted for an impalpable right testis and phimosis. At the time of surgical exploration, there appeared to be polyorchid testis on the right-hand side, with three masses that potentially appeared to be undescended testes. Discussion. Proponents of a conservative approach argue that infertility is common in patients with polyorchidism and, by preserving a potentially functional SNT, there may be improved spermatogenesis. When performing definitive surgical treatment, meticulous intra-abdominal and intrainguinal exploration must be undertaken. Orchiopexy should be performed to reduce the chances of torsion, malignancy, and infertility. Conclusion. Our case is important to the literature as it is the first known case of polyorchidism with 3 SNT on the right side, located intra-abdominally, and in a patient less than 1 year of age.

  1. Tisettanta case study: the interoperation of furniture production companies (United States)

    Amarilli, Fabrizio; Spreafico, Alberto

    This chapter presents the Tisettanta case study, focusing on the definition of the possible innovations that ICT technologies can bring to the Italian wood-furniture industry. This sector is characterized by industrial clusters composed mainly of a few large companies with international brand reputations and a large base of SMEs that manufacture finished products or are specialized in the production of single components/processes (such as the Brianza cluster, where Tisettanta operates). In this particular business ecosystem, ICT technologies can bring relevant support and improvements to the supply chain process, where collaborations between enterprises are put into action through the exchange of business documents such as orders, order confirmation, bills of lading, invoices, etc. The analysis methodology adopted in the Tisettanta case study refers to the TEKNE Methodology of Change (see Chapter 2), which defines a framework for supporting firms in the adoption of the Internetworked Enterprise organizational paradigm.

  2. Together we can make a difference: the case for transnational action for improved health in prisons. (United States)

    Easley, Cheryl E


    In spite of international differences in the treatment of incarcerated persons, as a group, they are vulnerable to poor health status and lack of access to quality health care. The health care of prisoners is affected by knowledge and commitment to ideas of human rights and social justice, as well as economic conditions. Prisoners are at increased risk of both acute and chronic diseases, and may constitute a threat to the health of other prisoners, their attendants or outside communities upon release. Mental illness and related problems of substance abuse are prevalent in prison populations, with many US prisons serving as modern asylums. Public health workers and organizations can stimulate and implement action to improve health in prisons. The World Federation of Public Health Associations can play a leadership role in co-ordinating and facilitating collaborative international action and research to enhance the health of prisoners and their communities worldwide.

    Full Text Available This paper introduces action research as a possible new method to reduce the distance between idealism and accounting practice, thus contributing to the accounting literature. The source of this paper is an on-going large research project. The project has three objectives. Firstly, to provide evidence of the utilisation of accounting methods in the Malaya plantation industry from its earliest beginnings through to the introduction of accounting tools such as budgets, leading to the creation of a social and economic underclass in Malaysia. Secondly, to examine the extent to which accounting information provided in the Annual Reports of Malaysian plantation companies is used in determining the wages of plantation workers on the grounds that workers in the plantation industry have been and still are, among the most poorly paid in Malaysia, and perhaps the world. Interestingly, the wages of plantation workers are determined through a negotiation process between the National Union of Plantation Workers and the Malaysian Agricultural Producers Association. This paper draws from this research project and explicates the utilisation of the Action Research methodology in reporting the “lived experiences” of those affected by Management Accounting budgets and demonstrating how the parties to wage negotiation, the employers, union and employees, can better derive value from accounting information provided within the annual reports of Malaysian plantation companies.

  5. Towards More Case Study Research in Entrepreneurship

    Directory of Open Access Journals (Sweden)

    Tom Duxbury


    Full Text Available Entrepreneurship as an emerging discipline has made good strides, but according to some, has fallen short of bringing its theory and literature up to the standards of others in the management sciences. Rich with the descriptive detail needed for insightful theory building in entrepreneurship, scholars have called for more case study research, particularly those incorporating non-retrospective and longitudinal observations. At the same time however, it has become rare to find such research published in A-level journals dedicated to entrepreneurship. A survey presented here of major entrepreneurship journals over the past six years revealed a publication rate of only 3% using the case study method. This presents a major impediment for developing fresh research in this field based upon the study of real cases. The author explores how the case study method has been applied to entrepreneurship research and provides recommendations for improved publication rates.

  10. Modalities of Generalization Through Single Case Studies. (United States)

    Zittoun, Tania


    The value of case studies for theory building is still doubted in psychology. The paper argues for the importance of case studies and the possibility of generalizing from these for a specific sociocultural understanding of human development. The paper first clarifies the notion of abduction within case studies, drawing on pragmatists James and Peirce and expanding it with the work of Lewin, and argues that it is the core mechanism that allows generalization from case studies. The second section presents the possibility of generalizing from individual single case studies, for which not only the subjective perspective, but also the dynamics by which the social and cultural environment guide and enable the person's development, have to be accounted for. The third section elaborates the question of institutional case studies, where the challenge is to account both for institutional dynamics, and for persons' trajectories within; this is exemplified with an ongoing study on the process of obtaining citizenship in Switzerland. The paper briefly concludes by highlighting two possible implications of the paper, one concerning the process of theoretical reasoning, the other, the fact that sociocultural psychology could itself be seen as an institution in-the-making.

  13. Performable Case Studies in Ethics Education. (United States)

    Robeson, Richard; King, Nancy M P


    Bioethics education often includes the study of short stories, novels, plays, and films, because such materials present case examples that can highlight relevant issues and questions especially vividly for a wide range of students. In addition, creative writing is widely used in the education of health professional students and in continuing education settings for health professionals. There are very few academic or professional disciplines that do not use case studies, but the case study in dialogic form has not been standard practice for thousands of years. Dramatic arts casuistry-the creation and performance of short case studies designed specifically to raise bioethics issues for discussion-represents an application of literature and the medical humanities that is both unique and uniquely valuable. This essay describes the development and history of a course that has been successfully taught to medical students and graduate bioethics students, in which the class researches, writes, and performs a case study designed to elicit reflection and discussion about a topic and set of bioethics issues of current interest to both academic and general audiences. The model is also suited to the presentation and discussion of existing case studies, both live and via on-demand audio.

  17. Incorporating self-management in prosthetic rehabilitation: case report of an integrated knowledge-to-action process. (United States)

    van Twillert, Sacha; Postema, Klaas; Geertzen, Jan H B; Lettinga, Ant T


    In improvement of clinical practice, unidirectional approaches of translating evidence into clinical practice have been pinpointed as main obstacles. The concept of engaged scholarship has been introduced to guide knowledge-to-action (KTA) processes, in which research knowledge and practical knowledge derived from therapists, patients, and organizational structures mutually inform each other. Accordingly, KTA experts should engage end-users earlier in knowledge translation and work in concert with them on both knowledge creation and knowledge implementation. The purposes of this case report are: (1) to provide an illustrative example of an evidence-informed improvement process in prosthetic rehabilitation in a local setting and (2) to articulate the bidirectional translation work incorporated into an integrated KTA process. A KTA expert translated research knowledge on self-management and task- and context-specific training into a functional prosthetic training program for patients with a lower limb amputation. Therapists contributed as co-creators to the translation process with practical knowledge of the specificities of the target group and local organizational context. The KTA expert moved the co-created knowledge into action in iterative and interactive steps with local therapists, patients, and managers. This bidirectional KTA translation process led to shared ownership of the functional prosthetic training program, in which self-management and task- and context-specific training principles and practices were integrated. Bidirectional knowledge translation builds on explicating and integrating the different knowledge practices of researchers, therapists, and their patients. Knowledge-to-action experts and end-users have their own roles and activities in such knowledge translation processes.

    Golooba-Mutebi, Frederick; Hickey, Sam


    The paradigm of 'inclusive neoliberalism' that currently characterises international development places a particular emphasis on community-based responses to the often structural problems of poverty and exclusion. Such approaches have become increasingly controversial: celebrated by optimists as the most empowering way forward for marginal citizens on the one hand, and derided as an abrogation of responsibility by development trustees by sceptics on the other. Uganda provides a particularly interesting context to explore these debates, not least because it has become a standard bearer for inclusive neoliberalism at the same time that regional inequalities within it have become increasingly apparent. Our investigation of the flagship response to deep impoverishment in its northern region, the World Bank-funded Northern Uganda Social Action Fund, offers greater support to the sceptics, not least because of the ways in which the more pernicious tendencies within inclusive neoliberalism have converged with the contemporary politics of development in Uganda.

  19. Rural case management: a pilot study. (United States)

    Beaulieu, J E; Hickman, M


    The long term goal of this research is to improve the quality, effectiveness and efficiency of home and community-based services for rural long term care clients. Case management has been espoused as one method to improve services. Long term care case management models have been tested in urban areas with good results, but it is not known to what extent these models are applicable to the special circumstances of rural home and community-based care. The purposes of this pilot study are: 1. To describe case management in long term home health care as practiced in rural Kentucky. 2. To analyze case management for factors that promote or impede effective and efficient delivery of long term home health care for older rural Kentuckians. 3. To propose a model appropriate to case management in long term home health care for older rural Americans.

    Andreeva, M., E-mail:; Groudev, P., E-mail:; Pavlova, M., E-mail:


    Highlights: • We validate operator actions in case of primary to secondary leakage. • We perform four scenarios related to SGTR accident for VVER-1000/V320. • The reference power plant for the analyses is Unit 6 at Kozloduy NPP. • The RELAP5/MOD 3.2 computer code is used in performing the analyses. • The analyses confirm the effectiveness of operator actions during PRISE. - Abstract: This paper presents the results of analytical validation of operator actions in case of “Steam Generator Tube Rupture” (SGTR) for VVER-1000/V320 units at Kozloduy Nuclear Power Plant (KNPP), done during the development of Symptom Based Emergency Operating Procedures (SB EOPs) for this plant. The purpose of the analyses is to demonstrate the ability to terminate primary to secondary leakage and to indicate an effective strategy for preventing secondary leakage to the environment and in this way to prevent radiological release to the environment. Following depressurization and cooldown of reactor coolant system (RCS) with isolation of the affected steam generator (SG), in these analyses are validated options for post-SGTR cooldown by: • back up filling the ruptured SG; • using letdown system in the affected SG and • by opening Fast Acting Isolation Valve (FAIV) and using Steam Dump Facility to the Condenser (BRU-K). The results of the thermal-hydraulic analyses have been used to assist KNPP specialists in analytical validation of EOPs. The RELAP5/MOD3.2 computer code has been used for the analyses in a VVER-1000 Nuclear Power Plant (NPP) model. A model of VVER-1000 based on Unit 6 of Kozloduy NPP has been developed for the thermal-hydraulics code RELAP5/MOD3.2 at the Institute for Nuclear Research and Nuclear Energy – Bulgarian Academy of Sciences (INRNE-BAS). This paper is possible through the participation of leading specialists from KNPP.

  1. Bridging the education-action gap: a near-peer case-based undergraduate ethics teaching programme. (United States)

    Kong, Wing May; Knight, Selena


    Undergraduate ethics teaching has made significant progress in the past decade, with evidence showing that students and trainee doctors feel more confident in identifying and analysing ethical issues. There is general consensus that ethics education should enable students and doctors to take ethically appropriate actions, and nurture moral integrity. However, the literature reports that doctors continue to find it difficult to take action when faced with perceived unethical behaviour. This has been evident in recent healthcare scandals, in which care has fallen below acceptable ethical standards, despite the presence of professional ethical guidelines and competencies. The National Foundation Training Programme forms the first 2 years of training for new UK doctors. We designed a Foundation Doctor (FD)-led teaching programme in which medical students were invited to bring cases and experiences from clinical placements for small group discussion facilitated by FDs. The aim was to enable students to act ethically in practice through developing moral sensitivity and moral identity, together with skills in ethical reasoning and tools to address barriers to taking ethical action. FDs were chosen as facilitators, based on the evidence that near-peer is an effective form of teaching in medicine and may provide positive role models for students. This article reviews the background rationale for the programme and its design. Important themes emerging from the case discussions are explored. Student and FD facilitator feedbacks are evaluated, and practical challenges to the implementation of this type of programme are discussed. Published by the BMJ Publishing Group Limited.

  3. Severity and exposure associated to tsunami actions in urban waterfronts. The case of Lisbon, Portugal. (United States)

    Conde, Daniel; Telhado, Maria J.; Viana Baptista, Maria A.; Antunes, Carlos M.; Ferreira, Rui M. L.


    discretization allows for resolving flow resistance associated to obstacles: no ad hoc formulations are needed to express drag on buildings, which is a key innovation in regard to previous studies. Additionally, vehicle-like particles were virtually placed over the major traffic nodes and routes, resulting in over 5000 lagrangian particles along the riverfront. This allows for an assessment of debris deposition patterns on the aftermath of the tsunami inundation. Severity is herein assumed to depend on hydrodynamic features of the tsunami, namely its capacity to impart momentum. Exposure to tsunami actions depends on the extent of the inundation. Both severity and exposure thus vary with the tsunami scenario considered. The obtained results, obtained with a high detail of hydrodynamic behavior, allow for a street-by-street quantification of severity, expressed in terms of the product of the depth-averaged velocity by the flow depth (Karvonen et al., 2000), herein the q-parameter. This parameter is shown to be larger during run-up, particularly in streets and narrow sections. It was observed that the scenario with greater exposure is a combination of a high-tide, a storm surge and a discharge equivalent to a 100 year flood on the Tagus River. The work conducted allows for designing a methodology for exposure assessment due to tsunami propagating over urban meshes, where the influence of the existing infrastructures on the incoming inundation is highly relevant. Such methodology, here applied to Lisbon waterfront, is general since it is defined in terms of quantifiable hydrodynamic variables.

  7. Complementary Actions

    Directory of Open Access Journals (Sweden)

    Luisa eSartori


    Full Text Available Complementary colors are color pairs which, when combined in the right proportions, produce white or black. Complementary actions refer here to forms of social interaction wherein individuals adapt their joint actions according to a common aim. Notably, complementary actions are incongruent actions. But being incongruent is not sufficient to be complementary (i.e., to complete the action of another person. Successful complementary interactions are founded on the abilities: (i to simulate another person’s movements, (ii to predict another person’s future action/s, (iii to produce an appropriate incongruent response which differ, while interacting, with observed ones, and (iv to complete the social interaction by integrating the predicted effects of one’s own action with those of another person. This definition clearly alludes to the functional importance of complementary actions in the perception–action cycle and prompts us to scrutinize what is taking place behind the scenes. Preliminary data on this topic have been provided by recent cutting-edge studies utilizing different research methods. This mini-review aims to provide an up-to-date overview of the processes and the specific activations underlying complementary actions.

  12. Determining climate change management priorities: A case study from Wisconsin (United States)

    LeDee, Olivia E.; Ribic, Christine


    A burgeoning dialogue exists regarding how to allocate resources to maximize the likelihood of long-term biodiversity conservation within the context of climate change. To make effective decisions in natural resource management, an iterative, collaborative, and learning-based decision process may be more successful than a strictly consultative approach. One important, early step in a decision process is to identify priority species or systems. Although this promotes the conservation of select species or systems, it may inadvertently alter the future of non-target species and systems. We describe a process to screen terrestrial wildlife for potential sensitivity to climate change and then use the results to engage natural resource professionals in a process of identifying priorities for monitoring, research, and adaptation strategy implementation. We demonstrate this approach using a case study from Wisconsin. In Wisconsin, experts identified 23 out of 353 species with sufficient empirical research and management understanding to inform targeted action. Habitat management and management of hydrological conditions were the common strategies for targeted action. Although there may be an interest in adaptation strategy implementation for many species and systems, experts considered existing information inadequate to inform targeted action. According to experts, 40% of the vertebrate species in Wisconsin will require near-term intervention for climate adaptation. These results will inform state-wide conservation planning as well as regional efforts.

  13. Case management at what expense? A case study of the emotional costs of case management. (United States)

    Beilman, J P; Sowell, R L; Knox, M; Phillips, K D


    Case management, which has its historical roots in community and public health, seeks to coordinate care, decrease costs, and promote access to appropriate levels of service. The case management system in this case study underscores the potential negative outcomes that can result from ignoring the holistic approach represented by an implemented case management system as a cost control mechanism. These negative outcomes not only include those expenditures of resources usually included when describing costs of care, but include those emotional costs of the system, patient, and care managers. Several needed system changes are identified and recommendations provided.

    Holoprosencephaly (HPE) is a rare and serious brain anomaly of heterogeneous aetiology. description of neuropathologic patterns of HPE to eventually integrate it into recognized syndrome The authors report 15 cases of HPE, examined at the department of pathology of Sousse (Tunisia) over a period of 11 years. The average age of mothers was 32 years and 46% of them were primigestes. The rate of consanguinity was 45%. The population of the study was formed of 13 foeti, 12 of which arose from a medical interruption of pregnancy, and 2 newborns. The average foetal age was of 25,5 weeks of gestation. Antenatal diagnosis was performed on ultrasounds signs represented by a hydrocephalus (7 cases), a microcephaly (4 cases), a harmonious delay of growth (3cas) and a facial dysmorphy (38%) dominated by cyclopia. Neuropathologic Exam identified 13 cases of alobair HPE and 2 cases semi lobar. The HPE was isolated in 2 cases with an unknown caryotype, it was syndromic in 13 cases, associated with a chromosome abnormality confirmed in 3 observations. The neonatal outcome of this deformation remains very poor justifying the interruption of pregnancy except in the lobar forms. An exhaustive domestic inquiry is compulsory to propose to parents a most adequate genetic counselling.

  16. Nanomaterial Case Study: A Comparison of Multiwalled ... (United States)

    The draft document is intended to be used as part of a process to identify what is known and, more importantly, what is not yet known that could be of value in assessing the broad implications of specific nanomaterials. Like previous case studies (see History/ Chronology below), this draft case study on multiwalled carbon nanotubes (MWCNTs) is based on the comprehensive environmental assessment (CEA) approach, which consists of both a framework and a process. Unlike previous case studies this case study incorporates information about a traditional (i.e., “non-nano-enabled”) product, against which the MWCNT flame-retardant coating applied to upholstery textiles (i.e., the “nano-enabled” product) can be compared. The comparative element serves dual-purposes: 1) to provide a more robust database that facilitates identification of data gaps related to the nano-enabled product and 2) to provide a context for identifying key factors and data gaps for future efforts to evaluate risk-related trade-offs between a nano-enabled and non-nano-enabled product. This draft case study does not represent a completed or even a preliminary assessment of MWCNTs; rather, it uses the CEA framework to structure information from available literature and other resources (e.g., government reports) on the product life cycle, fate and transport processes in various environmental media, exposure-dose characterization, and impacts in human, ecological, and environmental receptors.

  17. Management case study: Tampa Bay, Florida (United States)

    Morrison, Gerold; Greening, Holly; Yates, Kimberly K.; Wolanski, Eric; McLusky, Donald S.


    Tampa Bay, Florida, USA, is a shallow, subtropical estuary that experienced severe cultural eutrophication between the 1940s and 1980s, a period when the human population of its watershed quadrupled. In response, citizen action led to the formation of a public- and private-sector partnership (the Tampa Bay Estuary Program), which adopted a number of management objectives to support the restoration and protection of the bay’s living resources. These included numeric chlorophyll a and water-clarity targets, as well as long-term goals addressing the spatial extent of seagrasses and other selected habitat types, to support estuarine-dependent faunal guilds. Over the past three decades, nitrogen controls involving sources such as wastewater treatment plants, stormwater conveyance systems, fertilizer manufacturing and shipping operations, and power plants have been undertaken to meet these and other management objectives. Cumulatively, these controls have resulted in a 60% reduction in annual total nitrogen (TN) loads relative to earlier worse-case (latter 1970s) conditions. As a result, annual water-clarity and chlorophyll a targets are currently met in most years, and seagrass cover measured in 2008 was the highest recorded since 1950. Factors that have contributed to the observed improvements in Tampa Bay over the past several decades include the following: (1) Development of numeric, science-based water-quality targets to meet a long-term goal of restoring seagrass acreage to 1950s levels. Empirical and mechanistic models found that annual average chlorophyll a concentrations were a primary manageable factor affecting light attenuation. The models also quantified relationships between TN loads, chlorophyll a concentrations, light attenuation, and fluctuations in seagrass cover. The availability of long-term monitoring data, and a systematic process for using the data to evaluate the effectiveness of management actions, has allowed managers to track progress and

  6. Congruent and Incongruent Cues in Highly Familiar Audiovisual Action Sequences: An ERP Study

    Directory of Open Access Journals (Sweden)

    SM Wuerger


    Full Text Available In a previous fMRI study we found significant differences in BOLD responses for congruent and incongruent semantic audio-visual action sequences (whole-body actions and speech actions in bilateral pSTS, left SMA, left IFG, and IPL (Meyer, Greenlee, & Wuerger, JOCN, 2011. Here, we present results from a 128-channel ERP study that examined the time-course of these interactions using a one-back task. ERPs in response to congruent and incongruent audio-visual actions were compared to identify regions and latencies of differences. Responses to congruent and incongruent stimuli differed between 240–280 ms, 340–420 ms, and 460–660 ms after stimulus onset. A dipole analysis revealed that the difference around 250 ms can be partly explained by a modulation of sources in the vicinity of the superior temporal area, while the responses after 400 ms are consistent with sources in inferior frontal areas. Our results are in line with a model that postulates early recognition of congruent audiovisual actions in the pSTS, perhaps as a sensory memory buffer, and a later role of the IFG, perhaps in a generative capacity, in reconciling incongruent signals.

    Directory of Open Access Journals (Sweden)

    Golbarg Khorsand


    Full Text Available The aim of the present study is to re-establish the status of Archbishop Becket as a standard tragic hero of a religious play written by T. S. Eliot. Various critics have denounced the characterization of Archbishop Becket as a proper tragic hero, claiming that the entire process of the plot is devoid of ‘dramatic action', which is considered the backbone of any drama. In this paper the author has tried to illuminate on a renewed definition of ‘dramatic action' and consequently prove that the performance and actions of Archbishop Becket are, in fact, a process of mental action which nevertheless arrive the character to the definitive destination of all other dramatic heroes, i.e. a tragic death.

    Ransom, Khadijah S.; Johnson, Grace K.


    As a continuation from summer 2012, the Shuttle Case Study Collection has been developed using lessons learned documented by NASA engineers, analysts, and contractors. Decades of information related to processing and launching the Space Shuttle is gathered into a single database to provide educators with an alternative means to teach real-world engineering processes. The goal is to provide additional engineering materials that enhance critical thinking, decision making, and problem solving skills. During this second phase of the project, the Shuttle Case Study Collection website was developed. Extensive HTML coding to link downloadable documents, videos, and images was required, as was training to learn NASA's Content Management System (CMS) for website design. As the final stage of the collection development, the website is designed to allow for distribution of information to the public as well as for case study report submissions from other educators online.

  11. Generalizing from Case Studies: A Commentary. (United States)

    de Saint-Georges, Ingrid


    This commentary responds to the articles assembled for the thematic issue Self-identity on the move: methodological elaborations (IPBS, 51 (2), June 2017). The issue points in two directions. Firstly, the articles investigate the way individual self-identity develops in changing social and cultural environments, specifically in the contexts of family, youth and migration. Secondly, the special issue is also interested in methodological elaboration, more specifically the question of how one can generalize from individual case studies, especially when looking at complex, multiscale, semiotic processes. This commentary particularly addresses the second point and uses the various cases in this issue (i) to better understand something of the larger intellectual debate around the question of 'generalizing from case studies', and (ii) to reflect on writing as a tool for indexing generalization. The commentary highlights five textual moves the authors use to make their findings relevant beyond the specifics of the local study.

  12. Dissociating dynamic probability and predictability in observed actions – an fMRI study

    Directory of Open Access Journals (Sweden)

    Christiane eAhlheim


    Full Text Available The present fMRI study investigated whether human observers spontaneously exploit the statistical structure underlying continuous action sequences. In particular, we tested whether two different statistical properties can be distinguished with regard to their neural correlates: an action step’s predictability and its probability. To assess these properties we used measures from information theory. Predictability of action steps was operationalized by its inverse, conditional entropy, which combines the number of possible action steps with their respective probabilities. Probability of action steps was assessed using conditional surprisal, which increases with decreasing probability.Participants were trained in an action observation paradigm with video clips showing sequences of 9 to 33 seconds length with varying numbers of action steps that were statistically structured according to a Markov chain. Behavioral tests revealed that participants implicitly learned this statistical structure, showing that humans are sensitive towards these probabilistic regularities. Surprisal (lower probability enhanced the BOLD signal in the anterior intraparietal sulcus. In contrast, high conditional entropy, i.e. low predictability, was correlated with higher activity in dorsomedial prefrontal cortex, orbitofrontal gyrus, and posterior intraparietal sulcus. Furthermore, we found a correlation between the anterior hippocampus’ response to conditional entropy with the extent of learning, such that the more participants had learnt the structure, the greater the magnitude of hippocampus activation in response to conditional entropy.Findings show that two aspects of predictions can be dissociated: an action’s predictability is reflected in a top-down modulation of attentional focus, evident in increased fronto-parietal activation. In contrast, an action’s probability depends on the identity of the stimulus itself, resulting in bottom-up driven processing

  17. Modelling interspecific hybridization with genome exclusion to identify conservation actions: the case of native and invasive Pelophylax waterfrogs. (United States)

    Quilodrán, Claudio S; Montoya-Burgos, Juan I; Currat, Mathias


    Interspecific hybridization occurs in nature but can also be caused by human actions. It often leads to infertile or fertile hybrids that exclude one parental genome during gametogenesis, escaping genetic recombination and introgression. The threat that genome-exclusion hybridization might represent on parental species is poorly understood, especially when invasive species are involved. Here, we show how to assess the effects of genome-exclusion hybridization and how to elaborate conservation actions by simulating scenarios using a model of nonintrogressive hybridization. We examine the case of the frog Pelophylax ridibundus, introduced in Western Europe, which can hybridize with the native Pelophylax lessonae and the pre-existing hybrid Pelophylax esculentus, maintained by hybridogenesis. If translocated from Southern Europe, P. ridibundus produces new sterile hybrids and we show that it mainly threatens P. esculentus. Translocation from Central Europe leads to new fertile hybrids, threatening all native waterfrogs. Local extinction is demographically mediated via wasted reproductive potential or via demographic flow through generations towards P. ridibundus. We reveal that enlarging the habitat size of the native P. lessonae relative to that of the invader is a promising conservation strategy, avoiding the difficulties of fighting the invader. We finally stress that nonintrogressive hybridization is to be considered in conservation programmes.

  18. Estrogen Actions in the Brain and the Basis for Differential Action in Men and Women: A Case for Sex-Specific Medicines (United States)

    McArthur, Simon


    The classic view of estrogen actions in the brain was confined to regulation of ovulation and reproductive behavior in the female of all mamamalian species studied, including humans. Burgeoning evidence now documents profound effects of estrogens on learning, memory, and mood as well as neurodevelopmental and neurodegenerative processes. Most data derive from studies in females, but there is mounting recognition that estrogens play important roles in the male brain, where they can be generated from circulating testosterone by local aromatase enzymes or synthesized de novo by neurons and glia. Estrogen-based therapy therefore holds considerable promise for brain disorders that affect both men and women. However, as investigations are beginning to consider the role of estrogens in the male brain more carefully, it emerges that they have different, even opposite, effects as well as similar effects in male and female brains. This review focuses on these differences, including sex dimorphisms in the ability of estradiol to influence synaptic plasticity, neurotransmission, neurodegeneration, and cognition, which, we argue, are due in a large part to sex differences in the organization of the underlying circuitry. There are notable sex differences in the incidence and manifestations of virtually all central nervous system disorders, including neurodegenerative disease (Parkinson's and Alzheimer's), drug abuse, anxiety, and depression. Understanding the cellular and molecular basis of sex differences in brain physiology and responses to estrogen and estrogen mimics is, therefore, vitally important for understanding the nature and origins of sex-specific pathological conditions and for designing novel hormone-based therapeutic agents that will have optimal effectiveness in men or women.

  19. Onset and duration of action of topical antihistamine: a study of histamine skin test response. (United States)

    Danarti, Retno; Waskito, Fajar; Indrastuti, Niken


    Most patients who require skin prick testing cannot deal with their pruritus without taking antihistamines (AH). Orally administered AH has a quick onset of action, but it will suppress skin test responses (STR) from several days to weeks. In this study, we aimed to determine the onset and duration of action of single topical AH application by observing histamine-STR suppression over time. A two-step, randomized, intraindividual parallel-comparative, double-blind, placebo-controlled trial was conducted on the volar side of the forearm. Step 1 was aimed to determine the onset, while step 2 determined the duration of action. The topical AH tested was a single application of 5% doxepin hydrochloride cream, while 10 mg/ml histamine dihydrochloride was used to test the skin responses. Our 10 subjects' mean age was 35.8 +/- 3.179 years. Histamine wheal response was suppressed starting on minute 90 and the wheal width were back to >/= 7 mm(2 )on minute 270. Significant histamine reactivity difference between genders (P = 0.201) and atopic status (P = 1.000), which could be a source of bias in histamine STR, was not found among our subjects. Single application of topical AH has an onset of action in 90 min and duration of action skin prick testing after a few hours, without influencing the patient's STR.

  20. Nurses’ Empowerment in Self-Care Education to Stroke Patients: An Action Research Study

    Directory of Open Access Journals (Sweden)

    Zahra Aslani


    Full Text Available Background: Self-care needs are major problems among stroke patients. Nurses can support them through interventions such as education, a change in their attitude and emphasis on their remaining abilities. However, research has shown some weak points in the quality of care given to these patients. So the aim of this study was to improve the nurses’ practice in self-care education to stroke patients. Methods: This is a participatory action research, conducted in internal neurology ward of Al-Zahra hospital in Isfahan, Iran during 2013-2014 in five stages of diagnosis, planning, action, reflection and evaluation. Participants comprised 27 nursing personnel including staff nurses, matrons, educational supervisors and the staff in charge of Nurse Educators’ Al_Zahra Role Expansion Action Research (NEAREAR project. In the evaluation stage, data were collected from five personal interviews and two focus group discussions and analyzed by qualitative content analysis. Results: The findings of evaluation phase showed that during action research, approaching the nurses’ empowerment in self-care education to stroke patients has been set in motion. The nursing practice improvement, knowledge based practice, nurses’ attitude change, ability to respond against routinization, and motivation promotion emphasize the success of change process. Facilitators and barriers of educating patients are acknowledged by the participants as a factor influencing the continuation of change. Conclusions: The lack of nurses’ educating performance skills was overcome using action research and changes were made to improve the performance of nurses.

  2. Case studies in organic contaminant hydrogeology (United States)

    Baker, John A.


    The effective management of domestic solid waste and hazardous, toxic, and radioactive waste is a major problem in the area of environmental geology and water sciences over the world. This series of case studies of organic contaminants from both solid and hazardous waste disposal facilities provides examples of these problems. The facilities were investigated to determine risks and liabilities before acquisition, to determine the site hydrogeologic conditions for design of appropriate groundwater monitoring plans, and/or to determine the potential for groundwater contamination. The results of these studies and investigations by Waste Management Inc. (WMI) and its consultants have shown certain relationships in the distribution of organic pollutants to the different geologic and hydrogeologic charac teristics of each facility. In each of the case studies, all 129 priority pollutants were analyzed in private wells and/or monitoring wells at the request of regulatory agencies. The 31 volatile organic compounds (VOCs) of the priority pollutant list were the majority of the organic compounds detected and these data are evaluated in each case study. The case studies are on disposal facilities located in glacial tills, carbonaceous weathered clay soils, weathered shale, limestone bedrock, dolomite bedrock, and alluvial and sedimentary deposits. A brief discussion of groundwater quality impacts and remedial measures also is included.

  6. Emotional stimuli modulate readiness for action: a transcranial magnetic stimulation study. (United States)

    van Loon, Anouk M; van den Wildenberg, Wery P M; van Stegeren, Anda H; Hajcak, Greg; Ridderinkhof, K Richard


    Emotional stimuli may prime the motor system and facilitate action readiness. Direct evidence for this effect has been shown by recent studies using transcranial magnetic stimulation (TMS). When administered over the primary motor cortex involved in responding, TMS pulses elicit motor-evoked potentials (MEPs) in the represented muscles. The amplitudes of these MEPs reflect the state of corticospinal excitability. Here, we investigated the dynamic effects of induced emotions on action readiness, as reflected by corticospinal excitability. Subjects performed a choice task while viewing task-irrelevant emotional and neutral pictures. The pattern of MEP amplitudes showed a typical increase as the TMS pulse was presented closer in time to the imminent response. This dynamic pattern was amplified by both pleasant and unpleasant emotional stimuli, but more so when unpleasant pictures were viewed. These patterns present novel evidence in support of the notion that emotional stimuli modulate action readiness.

  7. Towards peer education prevention of school dropout: An exploratory analysis of an action-research study

    Directory of Open Access Journals (Sweden)

    Colucci Gabriella


    Full Text Available This paper presents the exploratory analysis of an action-research into dropout prevention in an Italian secondary school. By taking into account the representations of teachers, students and parents, different activities of peer education have been implemented during the school year in a city of Sardinia in order to promote school success. The study is based on a mixed-methods design, including focus groups with teachers, students and parents, as well as classroom observations. The action-research consists of different interventions: firstly, the participants’ representations of school dropout have been collected; then, a specific program of peer education has been proposed through activities of role-playing, simulations, brainstorming, and improvement of life skills (during training meetings with the participants. Thereafter, the action-research has been qualitatively analysed, with the findings indicating possible directions of re-creating school practices that could have potential benefits in preventing dropout.

  8. Professional relationships and power dynamics between urban community-based nurses and social work case managers: advocacy in action. (United States)

    Young, Staci


    The purpose of this study was to explore how community-based case managers interface with their clients' healthcare providers and other community organizations as a function within their advocacy efforts. Case managers previously defined advocacy as occurring at individual, organizational, and community levels. The relationships they attempt to develop and maintain are consistent with case management ideology, yet this is a complex process to ensure care for vulnerable populations with many medical and socioeconomic needs. Community-based case management settings. In-depth qualitative interviews with a total of 20 nurse and social work case managers working in public housing, university-affiliated community nursing centers, local parishes, and community ministry. The case managers in this study reflected on how they interface with their clients, other healthcare providers, and community organizations on behalf of their clients. They reflect on the importance of trust and communication to facilitate this process. The advocacy work of case managers is influenced by the setting, others' perceptions of their knowledge and expertise, and power dynamics. Their ability to effectively advocate is greatly influenced by the strength of the relationships they forge. Advocacy for vulnerable clients is influenced by the existing relationship between case managers and their clients' healthcare providers. Case managers need to be persistent in their interactions with other providers to ensure that their clients have access to valuable community resources. Clear lines of communication should be established between case managers so that there is clarity around roles and expectations in service provision. Case managers should also participate in the mentoring of future health professions students so they may learn the application of advocacy work in community settings.

  12. Habitual vs non-habitual manual actions: an ERP study on overt movement execution.

    Directory of Open Access Journals (Sweden)

    Jan Westerholz

    Full Text Available This study explored the neurophysiological mechanisms underlying the planning and execution of an overt goal-related handle rotation task. More specifically, we studied the neural basis of motor actions concerning the influence of the grasp choice. The aim of the present study was to differentiate cerebral activity between grips executed in a habitual and a non-habitual mode, and between specified and free grip choices. To our knowledge, this is the first study to differentiate cerebral activity underlying overt goal-related actions executed with a focus on the habitual mode. In a handle rotation task, participants had to use thumb-toward (habitual or thumb-away (non-habitual grips to rotate a handle to a given target position. Reaction and reach times were shorter for the habitual compared to the non-habitual mode indicating that the habitual mode requires less cognitive processing effort than the non-habitual mode. Neural processes for action execution (measured by event-related potentials (ERPs differed between habitual and non-habitual conditions. We found differential activity between habitual and non-habitual conditions in left and right frontal areas from -600 to 200 ms time-locked to reaching the target position. No differential neural activity could be traced for the specification of the grip. The results suggested that the frontal negativity reflected increased difficulty in movement precision control in the non-habitual mode compared to the habitual mode during the homing in phase of grasp and rotation actions.

    Full Text Available BACKGROUND We have studied 200 patients of pleural fluid presenting to our tertiary care centre. Presence of cases of pleural fluid is a common presentation both in pulmonary and extrapulmonary diseases. We analysed the patients having both exudates and transudates and studied the results. MATERIALS AND METHODS We selected patients above 20 years of age and classified the patients with pleural fluid as having transudates and exudates. We studied the causes of transudates and exudates. A total of 200 patients are studied in this prospective study. Diagnosis of pleural exudates is made on the basis of Light’s criteria, chest x-ray, pleural fluid analysis, CT scan in selected patients, sputum examination, bronchoscopy and bronchial washings. Moribund and non-cooperative patients and HIV positives were excluded from the study. RESULTS Among the 200 patients, 91% have exudates. 9% have transudates by Light’s criteria. Tuberculosis is the commonest cause of effusions (64.83% followed by malignancy (13.73% and sympneumonic or parapneumonic effusions (9.89%. Pleural effusions occurred predominantly in males. Prevalence of diabetes Mellitus among cases of tuberculous pleural effusions is 13.56%. Tuberculous effusions are predominantly right-sided. CONCLUSION Predominant cases of pleural fluid are exudates. Commonest cause of pleural effusion is Tuberculosis followed by malignancy both pulmonary and extrapulmonary and sym. and parapneumonic effusions. Prevalence of Diabetes among Tuberculous pleural effusion cases is more or less same as in general population. Cough, expectoration fever, chest pain and breathlessness are the common symptoms occurring in three fourths of the patients of tuberculous pleural effusion. Most of the cases of Tuberculous effusion are above 30 years of age. In the diagnosis of tuberculous pleural effusion, Pleural fluid ADA is very important.

    Full Text Available The preclinical experimental research concerning the study of the specific pharmacological action of "ArtpromentÒ" gel has been done. The gel developed contains propolis phenolic hydrophobic drug, articaine hydrochloride, menthol and rosemary oil in its composition. The medicine is planned to application in sports medicine with the purpose of treating traumatic injuries of organs of the locomotor apparatus accompanied with sport traumas (bruises, dislocations, sprains, ruptures of ligaments, tendons, etc.. In this work the pharmacological, physiological, instrumental methods of research and methods of mathematical statistics have been used. The study of the analgesic and local anesthetic action of the gel developed was conducted at the premises of the Central Research Laboratory of NUPh under the supervision of Doctor of Pharmacy, professor L.V.Iakovlieva on the model of tail thermoirritation in white rats weighing 180.0-200.0 g. The analgesic and local anesthetic actions were estimated by the ability of the medicine studied to change the pain threshold (duration of the latent period, sеc. in animals of the test group comparing to the control group in the dose of 25 mg/cm2 and the base in the dose of 30 mg/cm2 after application to the tail. The results of the experiment testify that when studying the influence of the combined gel on the course of the experimental nociceptive response of the central origin the significant analgesic action of "ArtpromentÒ" medicine has been determined; its highest intensity was observed in 2.5 and 3.5 hours after application and is 52 % and 59 %, respectively. Despite the fact that the progress of the pain syndrome in the model of tail thermoirritation is mediated by the central nervous system, it is possible to conclude that the developed gel has an expressed analgesic and local anesthetic action. The medicine shows the significant anti-edema action at the level of the reference medicine "Diclofen-gel" on the

  13. Recurrent perinatal loss: a case study. (United States)

    Kavanaugh, K; Robertson, P A


    To date, investigators have not demonstrated a clear relationship between a parent's history of prior perinatal losses and intensity of grief response following a subsequent perinatal loss. Examining this relationship for low-income, African-American parents is important because they are a vulnerable population due to the high incidence of perinatal mortality in Blacks and their other life stressors that can impact on grief response and caring needs. The purpose of this case study was to examine the impact of recurrent perinatal loss on a low-income African-American parent. The research design for this study was case report, using interview data collected from a mother who had recently experienced her fourth perinatal loss, which occurred at twenty-five weeks of gestation. Transcripts from two open-ended interviews were analyzed. The theoretical framework used to guide analysis of this case study was Lazarus and Folkman's stress and coping theory. Results demonstrated that the prior perinatal losses did not appear as critical components of the way the mother responded to her most recent loss. Instead, perception of the care she received from healthcare providers and how that care related to her experiences with her one living child who was born at the same gestational age was an important determinant in how she responded to her loss. The results of this case study demonstrate the importance assessing a person's perception of their experience and those factors which contribute to the way they respond.
