Community-based drinking water organizations have the responsibility in supplying water for domestic use to 29% of the Costa Rican population. Nowadays, more than 1.500 of these organizations face important challenges for achieving this critical mission, such as fulfilling national drinking-water quality standards, and improving their organization and administration to secure water supply and distribution under climate change. We conducted action-research in two communities with similar geographical and demographic conditions: Cuajiniquil and Colas de Gallo located in the drought prone Guanacaste region in Costa Rica. Both communities are contrasted regarding to their assets and organization. We addressed the following research question: Can a participatory process help communities assess the situation of their aqueduct and its management, project themselves in the future, and build more resilient strategies to face domestic water restrictions? Through 16 participatory sessions, we adapted the Wat-a-Game (WAG) toolkit to the problem of domestic water provision in these communities, creating the WAG-Tico role-playing game. This was complemented by two other activities: visits by regional actors sharing their experience, and exchange visits between both communities for cross-learning about community-based water management. The process resulted in a locally-led collaboration between both communities and the emergence of community commitments for improving drought resilience. WAG-Tico sensibilized participants to appreciate the value of community organization and the impacts of climate change on water supply, and develop aqueduct management rules. Exchange visits and regional actors interventions promoted opportunities for accessing to external resources (i.e. social, human and financial). Colas de Gallo created its first water committee for building a community aqueduct and their first drilled well. Cuajiniquil has committed in protecting its water springs, organized

The conservation of crop genetic resources requires understanding the different variables-cultural, social, and economic-that impinge on crop diversity. In small-scale farming systems, seed exchanges represent a key mechanism in the dynamics of crop genetic diversity, and analyzing the rules that structure social networks of seed exchange between farmer communities can help decipher patterns of crop genetic diversity. Using a combination of ethnobotanical and molecular genetic approaches, we investigated the relationships between regional patterns of manioc genetic diversity in Gabon and local networks of seed exchange. Spatially explicit Bayesian clustering methods showed that geographical discontinuities of manioc genetic diversity mirror major ethnolinguistic boundaries, with a southern matrilineal domain characterized by high levels of varietal diversity and a northern patrilineal domain characterized by low varietal diversity. Borrowing concepts from anthropology--kinship, bridewealth, and filiation--we analyzed the relationships between marriage exchanges and seed exchange networks in patrilineal and matrilineal societies. We demonstrate that, by defining marriage prohibitions, kinship systems structure social networks of exchange between farmer communities and influence the movement of seeds in metapopulations, shaping crop diversity at local and regional levels.

Euchner, Fabian; Schorlemmer, Danijel; Kästli, Philipp; Quakeml Working Group

2010-05-01

QuakeML is an XML-based data exchange standard for seismology that is in its fourth year of active community-driven development. The current release (version 1.2) is based on a public Request for Comments process that included contributions from ETH, GFZ, USC, SCEC, USGS, IRIS DMC, EMSC, ORFEUS, GNS, ZAMG, BRGM, Nanometrics, and ISTI. QuakeML has mainly been funded through the EC FP6 infrastructure project NERIES, in which it was endorsed as the preferred data exchange format. Currently, QuakeML services are being installed at several institutions around the globe, including EMSC, ORFEUS, ETH, Geoazur (Europe), NEIC, ANSS, SCEC/SCSN (USA), and GNS Science (New Zealand). Some of these institutions already provide QuakeML earthquake catalog web services. Several implementations of the QuakeML data model have been made. QuakePy, an open-source Python-based seismicity analysis toolkit using the QuakeML data model, is being developed at ETH. QuakePy is part of the software stack used in the Collaboratory for the Study of Earthquake Predictability (CSEP) testing center installations, developed by SCEC. Furthermore, the QuakeML data model is part of the SeisComP3 package from GFZ Potsdam. QuakeML is designed as an umbrella schema under which several sub-packages are collected. The present scope of QuakeML 1.2 covers a basic description of seismic events including picks, arrivals, amplitudes, magnitudes, origins, focal mechanisms, and moment tensors. Work on additional packages (macroseismic information, seismic inventory, and resource metadata) has been started, but is at an early stage. Contributions from the community that help to widen the thematic coverage of QuakeML are highly welcome. Online resources: http://www.quakeml.org, http://www.quakepy.org

Geography of community health information organization activity in the United States: Implications for the effectiveness of health information exchange.

Science.gov (United States)

Vest, Joshua R

The United States has invested nearly a billion dollars in creating community health information organizations (HIOs) to foster health information exchange. Community HIOs provide exchange services to health care organizations within a distinct geographic area. While geography is a key organizing principle for community HIOs, it is unclear if geography is an effective method for organization or what challenges are created by a geography-based approach to health information exchange. This study describes the extent of reported community HIO coverage in the United States and explores the practical and policy implications of overlaps and gaps in HIO service areas. Furthermore, because self-reported service areas may not accurately reflect the true extent of HIOs activities, this study maps the actual markets for health services included in each HIO. An inventory of operational community HIOs that included self-reported geographic markets and participating organizations was face-validated using a crowd-sourcing approach. Aggregation of the participating hospitals' individual health care markets provided the total geographic market served by each community HIO. Mapping and overlay analyses using geographic information system methods described the extent of community HIO activity in the United States. Evidence suggests that community HIOs may be inefficiently distributed. Parts of the United States have multiple, overlapping HIOs, while others do not have any providing health information exchange services. In markets served by multiple community HIOs, 45% of hospitals were participants of only one HIO. The current geography of community HIO activity does not provide comprehensive patient information to providers, nor community-wide information for public health agencies. The discord between the self-reported and market geography of community HIOs raises concerns about the potential effectiveness of health information exchange, illustrates the limitations of geography as

Smart health community: the hidden value of health information exchange.

Ciriello, James N; Kulatilaka, Nalin

2010-12-01

Investments in health information technology are accelerating the digitization of medicine. The value from these investments, however, can grow beyond efficiencies by filling the information gaps between the various stakeholders. New work processes, governance structures, and relationships are needed for the coevolution of healthcare markets and business models. But coevolution is slow, hindered by the scarcity of incentives for legacy delivery systems and constrained by the prevailing patient-healthcare paradigm. The greater opportunity lies in wellness for individuals, families, communities, and society at large: a consumer-community paradigm. Capturing new value from this opportunity can start with investment in health information exchange and the creation of Smart Health Communities. By shifting the focus of exchange from public servant to value-added service provider, these communities can serve as a platform for a wider array of wellness services from consumer care, traditional healthcare, and research.

As health care providers adopt and make "meaningful use" of health information technology (health IT), communities and delivery systems must set up the infrastructure to facilitate health information exchange (HIE) between providers and numerous other stakeholders who have a role in supporting health and care. By facilitating better communication and coordination between providers, HIE has the potential to improve clinical decision-making and continuity of care, while reducing unnecessary use of services. When implemented as part of a broader strategy for health care delivery system and payment reform, HIE capability also can enable the use of analytic tools needed for population health management, patient engagement in care, and continuous learning and improvement. The diverse experiences of seven communities that participated in the three-year federal Beacon Community Program offer practical insight into factors influencing the technical architecture of exchange infrastructure and its role in supporting improved care, reduced cost, and a healthier population. The case studies also document challenges faced by the communities, such as significant time and resources required to harmonize variations in the interpretation of data standards. Findings indicate that their progress developing community-based HIE strategies, while driven by local needs and objectives, is also influenced by broader legal, policy, and market conditions.

Access to accurate and trusted information is vital in preparing for, responding to, and recovering from an emergency. To facilitate response in large-scale emergency situations, Community Response Grids (CRGs) integrate Internet and mobile technologies to enable residents to report information, professional emergency responders to disseminate instructions, and residents to assist one another. CRGs use technology to help residents and professional emergency responders to work together in community response to emergencies, including bioterrorism events. In a time of increased danger from bioterrorist threats, the application of advanced information and communication technologies to community response is vital in confronting such threats. This article describes CRGs, their underlying concepts, development efforts, their relevance to biosecurity and bioterrorism, and future research issues in the use of technology to facilitate community response.

2009-09-01

We study the cluster dynamics of multichannel (multivariate) time series by representing their correlations as time-dependent networks and investigating the evolution of network communities. We employ a node-centric approach that allows us to track the effects of the community evolution on the functional roles of individual nodes without having to track entire communities. As an example, we consider a foreign exchange market network in which each node represents an exchange rate and each edge represents a time-dependent correlation between the rates. We study the period 2005-2008, which includes the recent credit and liquidity crisis. Using community detection, we find that exchange rates that are strongly attached to their community are persistently grouped with the same set of rates, whereas exchange rates that are important for the transfer of information tend to be positioned on the edges of communities. Our analysis successfully uncovers major trading changes that occurred in the market during the credit crisis.

The prevalence of dementia is increasing in Australia. Limited research is available on access to Cognitive Dementia and Memory Services (CDAMS) for people with dementia from Culturally and Linguistically Diverse (CALD) communities. This study aimed to determine the barriers and enablers to accessing CDAMS for people with dementia and their families of Chinese and Vietnamese backgrounds. Consultations with community members, community workers and health professionals were conducted using the "Cultural Exchange Model" framework. For carers, barriers to accessing services included the complexity of the health system, lack of time, travel required to get to services, language barriers, interpreters and lack of knowledge of services. Similarly, community workers and health professionals identified language, interpreters, and community perceptions as key barriers to service access. Strategies to increase knowledge included providing information via radio, printed material and education in community group settings. The "Cultural Exchange Model" enabled engagement with and modification of the approaches to meet the needs of the targeted CALD communities.

Community-Based Ecotourism: The Transformation of Local Community

2014-01-01

Full Text Available Community-based ecotourism (CBET is considered a sustainable form of tourism that improves the quality of life of hosts at the tourist destination. Scholars have yet to explore the long-term operation of CBET in relation to its effects on the local way of life. Consequently, the purpose of this paper is to examine the transformation of a local community due to the operation of CBET in relation to sociocultural, economic and environmental aspects. The findings reveal that the community encounters both positive and negative impacts of transformation. However, unintended impacts of the CBET operation lay embedded in the transformation of relationships among the community members. The study identifies that close relationships among the villagers has been initially transformed to loose relationships due to forgotten communal goals; CBET has transformed from being a conservation tool to being a business-oriented goal which causes conflicts of interest among local people and alters traditional social structure. The study also agrees with the notion of social exchange theory for villagers to enhance environmental sustainability, and proposes that slight inequalities of benefits received from CBET causes social transformation at the local level.

Exchanging ideas on climate change in the Yukon

International Nuclear Information System (INIS)

2000-01-01

Climate change models predict that Canada's North will receive the earliest and most extreme impacts of a changing climate. An increase in temperature could affect the Yukon economy, wildlife, traditional cultures and recreational activities. For this reason, the Northern Climate Exchange visited communities in the Yukon to exchange ideas with residents regarding observations and concerns about changes in weather and the land. The information obtained from the visits provides a better understanding of the situation and could help determine priorities for further research. The report showed that the residents are concerned about their observations, but public opinion on what do do about climate change varies among communities. While there are large amounts of local information on the subject, very little of it is documented. Very little research is available at a scale that is useful to community-level decision-making processes. This makes local observations even more valuable as they are in the best position to understand and assess their vulnerability to climate change. It was recommended that local and traditional knowledge on climate change be properly documented and that a community-based environmental monitoring strategy be developed. The final recommendation was to develop policy and decision-support tools. 3 tabs., 10 figs

Immediately after the accident at the Chernobyl NPP, both the International Atomic Energy Agency (IAEA) and the Commission of the European Communities (CEC) set up a system to meet the requirements for early warning and exchange of information. The Environment Institute of the CEC JRC-Ispra provides technical assistance for the European community Urgent Radiological Information Exchange system (ECURIE). By this system, Member State contact points can exchange information in a coded format. In order to facilitate the use and to assure the data quality, a Coding-Decoding Software (CDS) was developed in collaboration with the I.A.E.A. A new version, called CoDecS, is under development. An ECURIE data bank is under construction, which will automatically recognize and store incoming ECURIE messages. Further on, query and reporting software will be developed. The background objectives and the conceptual basis for the structure of the on-line information system is described. (author)

Reciprocal Exchange Patterned by Market Forces Helps Explain Cooperation in a Small-Scale Society.

Science.gov (United States)

Jaeggi, Adrian V; Hooper, Paul L; Beheim, Bret A; Kaplan, Hillard; Gurven, Michael

2016-08-22

Social organisms sometimes depend on help from reciprocating partners to solve adaptive problems [1], and individual cooperation strategies should aim to offer high supply commodities at low cost to the donor in exchange for high-demand commodities with large return benefits [2, 3]. Although such market dynamics have been documented in some animals [4-7], naturalistic studies of human cooperation are often limited by focusing on single commodities [8]. We analyzed cooperation in five domains (meat sharing, produce sharing, field labor, childcare, and sick care) among 2,161 household dyads of Tsimane' horticulturalists, using Bayesian multilevel models and information-theoretic model comparison. Across domains, the best-fit models included kinship and residential proximity, exchanges in kind and across domains, measures of supply and demand and their interactions with exchange, and household-specific exchange slopes. In these best models, giving, receiving, and reciprocating were to some extent shaped by market forces, and reciprocal exchange across domains had a strong partial effect on cooperation independent of more exogenous factors like kinship and proximity. Our results support the view that reciprocal exchange can provide a reliable solution to adaptive problems [8-11]. Although individual strategies patterned by market forces may generate gains from trade in any species [3], humans' slow life history and skill-intensive foraging niche favor specialization and create interdependence [12, 13], thus stabilizing cooperation and fostering divisions of labor even in informal economies [14, 15].

Helping E-Commerce Consumers Make Good Purchase Decisions: A User Reviews-Based Approach

Science.gov (United States)

Zhang, Richong; Tran, Thomas T.

Online product reviews provided by the consumers, who have previously purchased and used some particular products, form a rich source of information for other consumers who would like to study about these products in order to make their purchase decisions. Realizing this great need of consumers, several e-commerce web sites such as Amazon.com offer facilities for consumers to review products and exchange their purchase opinions. Unfortunately, reading through the massive amounts of product reviews available online from many e-communities, forums and newsgroups is not only a tedious task but also an impossible one. Indeed, nowadays consumers need an effective and reliable method to search through those huge sources of information and sort out the most appropriate and helpful product reviews. This paper proposes a model to discover the helpfulness of online product reviews. Product reviews can be analyzed and ranked by our scoring system and those reviews that may help consumers better than others will be found. In addition, we compare our model with a number of machine learning techniques. Our experimental results confirm that our approach is effective in ranking and classifying online product reviews.

Many schools rely upon community preceptors for office-based education of medical students. These preceptors struggle to balance clinical care with the learning needs of students. We aim to gain a deeper understanding of the teaching rewards and challenges of current community preceptors. Five schools' family medicine clerkship directors conducted in-depth interviews of two exemplary preceptors at each of their programs. Following qualitative analysis of the interviews, three directors conducted one focus group at their school. The individual and group interviews were recorded, transcribed, and analyzed using grounded theory. Exemplary community preceptors described strategies to improve the learning environment and specific teaching approaches. Well-known teaching strategies such as role modeling, adjusting instruction to the learner's needs, and selecting patients appropriate for a specific student were used. They also described newer techniques such as co-learning and integrating technology, for example, accessing online, current practice guidelines together with the student. They detailed challenges to teaching, including time constraints and too much content to cover and provided advice about teaching tools. While challenged by clinical demands, preceptors enjoyed teaching and found it rewarding. They used time-proven teaching strategies as well as technology and online resources to facilitate ambulatory teaching. Community preceptors continue to struggle to integrate learners and the priorities of the medical school curriculum into the clinical environment. Further development of electronic tools and other resources to support the teaching needs of preceptors may contribute to learning and help minimize preceptor burden.

Healthy End of Life Project (HELP): a progress report on implementing community guidance on public health palliative care initiatives in Australia.

Grindrod, Andrea; Rumbold, Bruce

2018-04-01

Contemporary end of life care policies propose increasing community capacity by developing sustainable skills, policies, structures, and resources to support members of a community in caring for each other at the end of life. Public health approaches to palliative care provide strategies to bring this about. Practical implementation can however be ineffective, principally due to failures to grasp the systemic nature of public health interventions, or to ensure that programs are managed and owned by community members, not the professionals who may have introduced them. This article outlines a comprehensive community development project that identifies local end of life needs and meets them through the efficient use of community resources. The project is the product of a three-phase enquiry. The first phase, carried out in a local community, examined carers' experiences of home-based dying, the networks that supported them during care, and broader community networks with the potential to extend care. Data were collected through in-depth research interviews, focus groups and consultation with a community research reference group. Findings were key issues to be targeted by a local community development strategy. In the second phase, these local findings were compared with other practice accounts to identify themes common to many contexts. A public health palliative care framework was then used to produce an evidence-informed community development model for end of life care. The third phase involves implementing and evaluating this model in different Australian contexts. A major theme emerging in phase one of the enquiry was the reluctance of carers to ask for, or even accept, offers of help from family, friends and community networks despite their evident need for support while providing end of life care at home. Others' willingness to provide support was thus hindered by uncertainty about what to offer, and concern about infringing on people's privacy. To develop

Aggregate-then-Curate: how digital learning champions help communities nurture online content

Andrew Whitworth

2012-12-01

Full Text Available Informational resources are essential for communities, rooting them in their own history, helping them learn and solve problems, giving them a voice in decision-making and so on. For digital inclusion – and inclusion in the informational and democratic processes of society more generally – it is essential that communities retain the skills, awareness and motivation to create and manage their own informational resources.This article explores a model for the creation of online content that incorporates the different ways in which the quality and relevance of information can be assured. This model, “Aggregate-then-Curate” (A/C, was developed from earlier work concerning digital inclusion in UK online centres, models of informal e-learning and ecologies of resources. A/C shows how creating online content can be viewed as a 7-step process, initiated by individuals but bringing in “digital learning champions”, other community members and formal educational institutions at different stages. A/C can be used to design training to help build the capacity to manage community informational resources in an inclusive way. The article then discusses and evaluates MOSI-ALONG, a Joint Information Systems Committee (JISC funded project founded on these ideas, which illustrates how A/C can be used to design training to help build the capacity to manage community informational resources in an inclusive way. This conclusion is supported by evaluations of the work done so far in MOSI-ALONG.

2011 PERFORMANCE ASSESSMENT COMMUNITY OF PRACTICE TECHNICAL EXCHANGE - SUMMARY

Energy Technology Data Exchange (ETDEWEB)

Seitz, R.

2011-12-30

The Performance Assessment Community of Practice (PA CoP) was developed in 2008 to improve consistency and quality in the preparation of performance assessments (PAs) and risk assessments across the Department of Energy (DOE) Complex. The term, PA, is used to represent all of these modeling applications in this report. The PA CoP goals are to foster the exchange of information among PA practitioners and to share lessons learned from PAs conducted for DOE, commercial disposal facilities, and international entities. Technical exchanges and workshops are a cornerstone of PA CoP activities. Previous technical exchanges have addressed Engineered Barriers (2009 - http://www.cresp.org/education/workshops/pacop/), the Advanced Simulation Capability for Environmental Management and the Cementitious Barriers Partnership (2010 - http://srnl.doe.gov/copexchange/links.htm). Each technical exchange also includes summary presentations regarding activities at DOE, the Nuclear Regulatory Commission (NRC) and other organizations (e.g., International Atomic Energy Agency (IAEA)) as well as a number of presentations from selected sites to provide insight and perspective from on-going modeling activities. Through the deployment of PA Assistance Teams, the PA CoP has also been engaged in the development of new PAs across the DOE Complex. As a way of improving consistency in the preparation of new PAs, the teams provide technical advice and share experiences, noteworthy practices, and lessons learned from previous Low-Level Waste Disposal Facility Federal Review Group (LFRG) reviews. Teams have provided support for PAs at Hanford, Idaho, Paducah and Portsmouth. The third annual PA CoP Technical Exchange was held on May 25-26, 2011 in Atlanta, GA. The PA CoP Steering Committee Meeting held its first meeting on May 24 prior to the Technical Exchange. Decision making using models and software quality assurance were the topical emphasis for the exchange. A new feature at the 2011 technical

Quantum-chemical study of the exchange processes in hydrogen bonding complexes will allow us to achieve progress in the understanding of the elementary act mechanism of proton transfer in hydrogen bonding chain as well as the essence of the acid-base interactions. Oxymethyl radical •CH2ОН is small in size and comfortable as a model particle that well transmits protolytic properties of paramagnetic acids having more complex structure. Quantum-chemical modeling of proton exchange reaction oxymethyl radical ∙CH2OH and its diamagnetic analog CH3OH with amines, carboxylic acids and water was carried out using UAM1 method with the help of Gaussian-2009 program. QST2 method was used for the search of transition state, IRC procedure was applied for the calculation of descents along the reaction coordinate. The difference in the structure of transition states of ∙CH2OH/ CH3OH with bases and acids has been shown. It has been confirmed that in the case of bases, consecutive proton exchange mechanism was fixed, and in the case of complexes with carboxylic acids parallel proton exchange mechanism was fixed. The similarity in the reaction behavior of paramagnetic and diamagnetic systems in the proton exchange has been found. It was suggested that the mechanism of proton exchange reaction is determined by the structure of the hydrogen bonding cyclic complex, which is, in turn, depends from the nature of the acid-base interactions partners.

Efforts to involve parents and families in all aspects of research, from initiating the question through to dissemination and knowledge exchange, are increasing. While social media as a method for health communication has shown numerous benefits, including increasing accessibility, interactions with others, and access to health care information, little work has been published on the use of social media to enhance research partnerships. Our objective was to describe the development and evaluation of a Web-based research advisory community, hosted on Facebook and connecting a diverse group of parents of special needs children with researchers at CanChild Centre for Childhood Disability Research. The goal of this community is to work together and exchange knowledge in order to improve research and the lives of children and their families. The Web-based Parents Participating in Research (PPR) advisory community was a secret Facebook group launched in June 2014 and run by 2 parent moderators who worked in consultation with CanChild. We evaluated its success using Facebook statistics of engagement and activity (eg, number of posts, number of comments) between June 2014 and April 2015, and a Web-based survey of members. The PPR community had 96 participants (2 parent moderators, 13 researchers, and 81 family members) as of April 1, 2015. Over 9 months, 432 original posts were made: 155 (35.9%) by moderators, 197 (45.6%) by parents, and 80 (18.5%) by researchers. Posts had a median of 3 likes (range 0-24) and 4 comments (range 0-113). Members, rather than moderators, generated 64% (277/432) of posts. The survey had a 51% response rate (49/96 members), with 40 (82%) being parent members and 9 (18%) being researchers. The initial purpose of the group was to be an advisory to CanChild, and 76% (28/37) of parents and all the researchers (9/9) identified having an impact on childhood disability research as their reason for participating. A total of 58% (23/40) of parents and 56

Stigma related to mental illness affects all ethnic groups, contributing to the production and maintenance of mental illness and restricting access to care and support. However, stigma is especially prevalent in minority communities, thus potentially increasing ethnically based disparities. Little is known of the links between stigma and help-seeking for mental illness in African-descended populations in the UK. Building on the evidence that faith-based organizations (FBOs) can aid the development of effective public health strategies, this qualitative study used semi-structured interviews with faith groups to explore the complex ways in which stigma influences help-seeking for mental illness in African-descended communities. A thematic approach to data analysis was applied to the entire data set. Twenty-six men and women who had varying levels of involvement with Christian FBOs in south London were interviewed (e.g. six faith leaders, thirteen 'active members' and seven 'regular attendees'). Key factors influencing help-seeking behaviour were as follows: beliefs about the causes of mental illness; 'silencing' of mental illness resulting from heightened levels of ideological stigma; and stigma (re)production and maintenance at community level. Individuals with a diagnosis of mental illness were likely to experience a triple jeopardy in terms of stigma. 'One-size-fits-all' approaches cannot effectively meet the needs of diverse populations. To ensure that services are more congruent with their needs, health and care organizations should enable service users, families and community members to become active creators of interventions to remove barriers to help-seeking for mental illness. © 2016 The Authors.

For communities, the value of community-based participatory research (CBPR) is often manifested in the outcomes of increased capacity and sustainable adoption of evidence-based practices for social change. Educational opportunities that promote discourse between community and academic partners can help to advance CBPR and better define these outcomes. This paper describes a community-academic conference to develop shared definitions of community capacity building and sustainability related to CBPR and to identify obstacles and facilitators to both. "Taking It to the Curbside: Engaging Communities to Create Sustainable Change for Health" was planned by five Clinical Translational Science Institutes and four community organizations. After a keynote presentation, breakout groups of community and academic members met to define community capacity building and sustainability, and to identify facilitators and barriers to achieving both. Groups were facilitated by researcher-community partner teams and conversations were recorded and transcribed. Qualitative analysis for thematic content was conducted by a subset of the planning committee. Important findings included learning that (1) the concepts of capacity and sustainability were considered interconnected; (2) partnership was perceived as both a facilitator and an outcome of CBPR; (3) sustainability was linked to "transfer of knowledge" from one generation to another within a community; and (4) capacity and sustainability were enhanced when goals were shared and health outcomes were achieved. Community capacity building and sustainability are key outcomes of CBPR for communities. Co-learning opportunities that engage and mutually educate both community members and academics can be useful strategies for identifying meaningful strategies to achieve these outcomes.

Beyond vertical integration--Community based medical education.

Science.gov (United States)

Kennedy, Emma Margaret

2006-11-01

The term 'vertical integration' is used broadly in medical education, sometimes when discussing community based medical education (CBME). This article examines the relevance of the term 'vertical integration' and provides an alternative perspective on the complexities of facilitating the CBME process. The principles of learner centredness, patient centredness and flexibility are fundamental to learning in the diverse contexts of 'community'. Vertical integration as a structural concept is helpful for academic organisations but has less application to education in the community setting; a different approach illuminates the strengths and challenges of CBME that need consideration by these organisations.

The objectives of this study are to better understand the lived experience of food insecurity in our community and to examine the impact of a community-based program developed to increase access to local, healthy foods. Participants were given monthly vouchers to spend at local farmers' markets and invited to engage in a variety of community activities. Using a community-based participatory research framework, mixed methods were employed. Survey results suggest that most respondents were satisfied with the program and many increased their fruit and vegetable consumption. However, over 40% of respondents reported a higher level of stress over having enough money to buy nutritious meals at the end of the program. Photovoice results suggest that the program fostered cross-cultural exchanges, and offered opportunities for social networking. Building on the many positive outcomes of the program, community partners are committed to using this research to further develop policy-level solutions to food insecurity.

Students as effective harm reductionists and needle exchange organizers.

Barbour, Kyle; McQuade, Miriam; Brown, Brandon

Needle exchange programs are safe, highly effective programs for promoting health among people who inject drugs. However, they remain poorly funded, and often illegal, in many places worldwide due to fear and stigma surrounding drug use. Continued advocacy, education, and implementation of new needle exchanges are thus essential to improve public health and reduce structural inequality. We argue that students, and especially professional and graduate students, have the potential to play an important role in advancing harm reduction. Students benefit from the respect given to the professions they are training to enter, which gives them leverage to navigate the political hurdles often faced by needle exchange organizers, especially in areas that presently lack services. In addition, due to their relative simplicity, needle exchanges do not require much of the licensing, clinical knowledge, and infrastructure associated with more traditional student programs, such as student-run free medical clinics. Students are capable of learning harm reduction cultural approaches and techniques if they remain humble, open-minded, and seek the help of the harm reduction community. Consequently, students can generate tremendous benefits to their community without performing beyond their appropriate clinical limitations. Students benefit from organizing needle exchanges by gaining applied experience in advocacy, organization-building, and political finesse. Working in a needle exchange significantly helps erode stigma against multiple marginalized populations. Students in health-related professions additionally learn clinically-relevant knowledge that is often lacking from their formal training, such as an understanding of structural violence and inequality, root causes of substance use, client-centered approaches to health services, and interacting with clients as peers, rather than through the standard hierarchical medical interaction. We therefore encourage students to learn about

Adaptive Management and Social Learning in Collaborative and Community-Based Monitoring: a Study of Five Community-Based Forestry Organizations in the western USA

Directory of Open Access Journals (Sweden)

Maria E. Fernandez-Gimenez

2008-12-01

Full Text Available Collaborative and community-based monitoring are becoming more frequent, yet few studies have examined the process and outcomes of these monitoring approaches. We studied 18 collaborative or community-based ecological assessment or monitoring projects undertaken by five community-based forestry organizations (CBFs, to investigate the objectives, process, and outcomes of collaborative ecological monitoring by CBF organizations. We found that collaborative monitoring can lead to shared ecological understanding among diverse participants, build trust internally and credibility externally, foster social learning and community-building, and advance adaptive management. The CBFs experienced challenges in recruiting and sustaining community participation in monitoring, building needed technical capacity for monitoring, and communicating monitoring results back to the broader community. Our results suggest that involving diverse and sometimes adversarial interests at key points in the monitoring process can help resolve conflicts and advance social learning, while also strengthening the link between social and ecological systems by improving the information base for management and increasing collective awareness of the interdependence of human and natural forest communities.

Ion exchange behaviour of citrate and EDTA anions on strong and weak base organic ion exchangers

International Nuclear Information System (INIS)

Askarieh, M.M.; White, D.A.

1988-01-01

The exchange of citrate and EDTA ions with two strong base and two weak base exchangers is considered. Citrate and EDTA analysis for this work was performed using a colorimetric method developed here. The ions most selectively exchanged on the resins are H 2 cit - and H 2 EDTA 2- , though EDTA is generally less strongly sorbed on strong base resins. In contact with weak base resins, deprotonation of the resin occurs during ion exchange with a noticeable drop in solution pH. Although EDTA sorption can be reversed by nitric acid, citrate ions are significantly held on the resin at low pH. The exchange of citrate can be made reversible if bicarbonate is added to the initial solutions. Alkaline regeneration of exchangers loaded with EDTA proved to be very effective. (author)

Exploring Business Strategy in Health Information Exchange Organizations.

Unlike consumer goods industries, healthcare has been slow to implement technolo gies that support exchange of data in patients' health records. This results in avoid able medication errors, avoidable hospital readmissions, unnecessary duplicate testing, and other inefficient or wasteful practices. Community-based regional health information exchange (HIE) organizations have evolved in response to federal aims to encourage interoperability, yet little is known about their strategic approach. We use the lens of institutional and strategic management theories to empirically explore the differences in business strategies deployed in HIEs that are, to date, financially sustainable versus those that are not. We developed a 20-question survey targeted to CEOs to assess HIE business strategies. Our sample consisted of 60 community-based exchanges distributed throughout the United States, and we achieved a 58% response rate. Questions centered on competitive strategy and financial sustainability. We relied on logistic regression methods to explore relationships between variables. Our regression identified characteristics common to sustainable organizations. We defined sustainability as revenues exceeding operational costs. Seventeen of the 35 organizations (49%) defined themselves as currently sustainable. Focus and cost leadership strategies were significantly associated with sustainability. Growth strate gies, which were much more common than other strategies, were not associated with sustainability. We saw little evidence of a differentiation strategy (i.e., the basis of competition whereby the attributes of a product or service are unmatched by rivals). Most CEOs had a relatively optimistic outlook, with 60% stating they were confident of surviving over the next 5 years; however, nearly 9% of the organizations were in some phase of divestiture or exit from the market. HIEs are evolving differently based on local leadership decisions, yet their strategic approach is

The effective care and well-being of a community is a challenging task especially in an emergency situation. Traditional technology-based silos between health and emergency services are challenged by the changing needs of the community that could benefit from integrated health and safety services. Low-cost smart-home automation solutions, wearable devices and Cloud technology make it feasible for communities to interact with each other, and with health and emergency services in a timely manner. This paper proposes a new community-based care model, supported by technology, that aims at reducing healthcare and emergency services costs while allowing community to become resilient in response to health and emergency situations. We looked at models of care in different industries and identified the type of technology that can support the suggested new model of care. Two prototypes were developed to validate the adequacy of the technology. The result is a new community-based model of care called 'Le Bon Samaritain'. It relies on a network of people called 'Bons Samaritains' willing to help and deal with the basic care and safety aspects of their community. Their role is to make sure that people in their community receive and understand the messages from emergency and health services. The new care model is integrated with existing emergency warning, community and health services. Le Bon Samaritain model is scalable, community-based and can help people feel safer, less isolated and more integrated in their community. It could be the key to reduce healthcare cost, increase resilience and drive the change for a more integrated emergency and care system.

Age-friendly initiatives are increasingly promoted as a policy solution to healthy aging, The primary objective of this article was to examine older adults' and key stakeholders' perceptions of the factors that either help or hinder a community from becoming age-friendly in the context of rural Manitoba, a Canadian prairie province. Twenty-four older adults and 17 key informants completed a qualitative interview. The findings show that contextual factors including size, location, demographic composition, ability to secure investments, and leadership influence rural communities' ability to become age-friendly. Government must consider the challenges these communities face in becoming more age-friendly and develop strategies to support communities. © The Author(s) 2013.

Community-based first aid training is the collaborative development of locally relevant emergency response training. The Sachigo Lake Wilderness Emergency Response Education Initiative was developed, delivered, and evaluated through two intensive 5-day first aid courses. Sachigo Lake First Nation is a remote Aboriginal community of 450 people in northern Ontario, Canada, with no local paramedical services. These courses were developed in collaboration with the community, with a goal of building community capacity to respond to medical emergencies. Most first aid training programs rely on standardized curriculum developed for urban and rural contexts with established emergency response systems. Delivering effective community-based first aid training in a remote Aboriginal community required specific adaptations to conventional first aid educational content and pedagogy. Three key lessons emerged during this program that used collaborative principles to adapt conventional first aid concepts and curriculum: (1) standardized approaches may not be relevant nor appropriate; (2) relationships between course participants and the people they help are relevant and important; (3) curriculum must be attentive to existing informal and formal emergency response systems. These lessons may be instructive for the development of other programs in similar settings.

Aloui, Chaker; Jammazi, Rania

2015-10-01

In this article, we propose a wavelet-based approach to accommodate the stylized facts and complex structure of financial data, caused by frequent and abrupt changes of markets and noises. Specifically, we show how the combination of both continuous and discrete wavelet transforms with traditional financial models helps improve portfolio's market risk assessment. In the empirical stage, three wavelet-based models (wavelet-EGARCH with dynamic conditional correlations, wavelet-copula, and wavelet-extreme value) are considered and applied to crude oil price and US dollar exchange rate data. Our findings show that the wavelet-based approach provides an effective and powerful tool for detecting extreme moments and improving the accuracy of VaR and Expected Shortfall estimates of oil-exchange rate portfolios after noise is removed from the original data.

Local knowledge in disaster management should not be neglected in developing community resilience. The circular relation between humans and their living habitat and community social relation have developed the local knowledge namely specialized knowledge, shared knowledge, and common knowledge. Its correlation with community-based disaster management has become an important discussion specially to answer can local knowledge underlie community-based disaster risk reduction concept development? To answer this question, this research used mix-method. Interview and crosstab method for 73 respondents with 90% trust rate were used to determine the correlation between local knowledge and community characteristics. This research found out that shared knowledge dominated community local knowledge (77%). While common knowledge and specialized knowledge were sequentially 8% and 15%. The high score of shared value (77%) indicated that local knowledge was occurred in household level and not yet indicated in community level. Shared knowledge was found in 3 phases of the resilient community in dealing with disaster, namely mitigation, emergency response, and recovery phase. This research, therefore, has opened a new scientific discussion on the self-help concept in community-help concept in CBDRM concept development in Indonesia.

Role of Knowledge Based Communities in Knowledge Process

Full Text Available In the new economy, knowledge is an essential component of economic and social systems. The organizational focus has to be on building knowledge-based management, development of human resource and building intellectual capital capabilities. Knowledge-based management is defined, at company level, by economic processes that emphasize creation, selling, buying, learning, storing, developing, sharing and protection of knowledge as a decisive condition for profit and long-term sustainability of the company. Hence, knowledge is, concurently, according to a majoritiy of specialists, raw material, capital, product and an essential input. Knowledge-based communities are one of the main constituent elements of a framework for knowledge based management. These are peer networks consisting of practitioners within an organization, supporting each other to perform better through the exchange and sharing of knowledge. Some large companies have contributed or supported the establishment of numerous communities of practice, some of which may have several thousand members. They operate in different ways, are of different sizes, have different areas of interest and addresses knowledge at different levels of its maturity. This article examines the role of knowledge-based communities from the perspective of knowledge based management, given that the arrangements for organizational learning, creating, sharing, use of knowledge within organizations become more heterogeneous and take forms more difficult to predict by managers and specialists.

Efficient Fair Exchange from Identity-Based Signature

Science.gov (United States)

Yum, Dae Hyun; Lee, Pil Joong

A fair exchange scheme is a protocol by which two parties Alice and Bob exchange items or services without allowing either party to gain advantages by quitting prematurely or otherwise misbehaving. To this end, modern cryptographic solutions use a semi-trusted arbitrator who involves only in cases where one party attempts to cheat or simply crashes. We call such a fair exchange scheme optimistic. When no registration is required between the signer and the arbitrator, we say that the fair exchange scheme is setup free. To date, the setup-free optimist fair exchange scheme under the standard RSA assumption was only possible from the generic construction of [12], which uses ring signatures. In this paper, we introduce a new setup-free optimistic fair exchange scheme under the standard RSA assumption. Our scheme uses the GQ identity-based signature and is more efficient than [12]. The construction can also be generalized by using various identity-based signature schemes. Our main technique is to allow each user to choose his (or her) own “random” public key in the identitybased signature scheme.

2011-04-01

Full Text Available QuakeML is an XML-based data exchange standard for seismology that is in its fourth year of active community-driven development. Its development was motivated by the need to consolidate existing data formats for applications in statistical seismology, as well as setting a cutting-edge, community-agreed standard to foster interoperability of distributed infrastructures. The current release (version 1.2 is based on a public Request for Comments process and accounts for suggestions and comments provided by a broad international user community. QuakeML is designed as an umbrella schema under which several sub-packages are collected. The present scope of QuakeML 1.2 covers a basic description of seismic events including picks, arrivals, amplitudes, magnitudes, origins, focal mechanisms, and moment tensors. Work on additional packages (macroseismic information, ground motion, seismic inventory, and resource metadata has been started, but is at an early stage. Several applications based on the QuakeML data model have been created so far. Among these are earthquake catalog web services at the European Mediterranean Seismological Centre (EMSC, GNS Science, and the Southern California Earthquake Data Center (SCEDC, and QuakePy, an open-source Python-based seismicity analysis toolkit. Furthermore, QuakeML is being used in the SeisComP3 system from GFZ Potsdam, and in the Collaboratory for the Study of Earthquake Predictability (CSEP testing center installations, developed by Southern California Earthquake Center (SCEC. QuakeML is still under active and dynamic development. Further contributions from the community are crucial to its success and are highly welcome.

Mental Health Attitudes and Beliefs in a Community Sample on the Central Coast in Australia: Barriers to Help Seeking.

Coates, Dominiek; Saleeba, Christine; Howe, Deborah

2018-03-27

There continues to be call for greater community awareness actions and strategies to reduce stigma and enhance mental health literacy nationally and internationally. To identify local barriers to help-seeking and perceptions around stigma, we developed a 'mental health attitudes and beliefs' survey which was administered at a range of community events on the Central Coast in New South Wales, Australia. The aim was for the results of this survey to inform the development of strategies that enhance local help-seeking behaviours that are sensitive to the role of age, gender and Indigenous status. People who approached our Mental Health Information stall were invited to complete the survey and 282 individuals completed the survey. The data was analysed descriptively with a focus on comparing subgroups based on age, gender, Indigenous status, and previous service access or experience of mental illness. Cost, stigma and mental health literacy were found to be prominent barriers to help-seeking for the overall cohort; however, the ways in which or extent to which these barriers impact on help seeking varied between subgroups. A discussion of these differences and their implications for practice is the focus of this paper.

Water exchange colonoscopy has been reported to reduce examination discomfort and to provide salvage cleansing in unsedated or minimally sedated patients. The prolonged insertion time and perceived difficulty of insertion associated with water exchange have been cited as a barrier to its widespread use. To assess the feasibility of learning and using the water exchange method of colonoscopy in a U.S. community practice setting. Quality improvement program in nonacademic community endoscopy centers. Patients undergoing sedated diagnostic, surveillance, or screening colonoscopy. After direct coaching by a knowledgeable trainer, an experienced colonoscopist initiated colonoscopy using the water method. Whenever >5 min elapsed without advancing the colonoscope, conversion to air insufflation was made to ensure timely completion of the examination. Water Method Intention-to-treat (ITT) cecal intubation rate (CIR). Female patients had a significantly higher rate of past abdominal surgery and a significantly lower ITTCIR. The ITTCIR showed a progressive increase over time in both males and females to 85-90%. Mean insertion time was maintained at 9 to 10 min. The overall CIR was 99%. Use of water exchange did not preclude cecal intubation upon conversion to usual air insufflation in sedated patients examined by an experienced colonoscopist. With practice ITTCIR increased over time in both male and female patients. Larger volumes of water exchanged were associated with higher ITTCIR and better quality scores of bowel preparation. The data suggest that learning water exchange by a busy colonoscopist in a community practice setting is feasible and outcomes conform to accepted quality standards.

To describe the incorporation of a state health information exchange (HIE) into a community pharmacy transitions of care (TOC) service and to assess its impact on 30-day readmission rates. Three suburban community pharmacies in Olathe, Kansas. Balls Food Stores is a grocery store chain which operates 21 supermarket community pharmacies in the Kansas City metropolitan area. Balls Food Stores launched a pharmacist-led self-referral TOC study in which a state HIE was utilized to collect discharge information from patients' electronic medical records (EMRs) to facilitate TOC comprehensive medication reviews (CMRs). Descriptive statistics were used to assess types and outcomes of identified drug therapy problems and the ability to access Kansas Health Information Network EMRs. A chi-square test was used to assess 30-day readmissions between patients who accepted and declined the service. Forty patients were identified for inclusion and 18 elected to participate in the service. The majority of participants were white females with a median age of 64.5 years. Out of 40 study patients, 85% had an EMR available; 12.5% of patients had a medication list included in their EMR hospitalization documentation. Participants who underwent the service had a statistically significantly lower rate of overall 30-day hospital readmission than those who declined (11.1% vs 36.4%, P = 0.032). Among the 18 TOC CMRs performed, 90 drug therapy problems were identified and 77 were resolved in collaboration with a patient, caregiver, or physician. Incorporation of a state HIE into a community pharmacist-led TOC service is a novel strategy for collecting patient data. During the study, no TOC participants were readmitted within 30 days. However, pharmacists found HIE data alone was insufficient to perform TOC CMRs for the majority of participants. In order to expand state HIE utilization, more health systems will need to upload a minimum standard data set to help facilitate care. Copyright © 2018

Federal and state agencies are investing substantial resources in the creation of community health information exchanges, which are consortia that enable independent health care organizations to exchange clinical data. However, under pressure to form accountable care organizations, medical groups may merge and support private health information exchanges. Such activity could reduce the potential utility of community exchanges-that is, the exchanges' capacity to share patient data across hospitals and physician practices that are independent. Simulations of care transitions based on data from ten Massachusetts communities suggest that there would have to be many such mergers to undermine the potential utility of health information exchanges. At the same time, because hospitals and the largest medical groups account for only 10-20 percent of care transitions in a community, information exchanges will still need to recruit a large proportion of the medical groups in a given community for the exchanges to maintain their usefulness in fostering information exchange across independent providers.

2014-09-01

Great strides have been made in improving heart health in the United States during the last 2 decades, yet these strides have not encompassed many ethnic minority populations. There are significant health disparity gaps stemming from both a paucity of valid research and a lack of culturally sensitive interventions. In particular, many Korean Americans with chronic illnesses encounter difficulty navigating the healthcare system because of limited health literacy. The effect of a multimodal Self-Help Intervention Program on the Control of High Blood Pressure (HBP) was tested in a community-based clinical trial for Korean American seniors. Of 440 seniors enrolled, 369 completed the study (184 in the intervention group and 185 in the control group; mean age = 70.9±5.3 years). The intervention group received 6 weekly educational sessions on HBP management skill building, including health literacy training, followed by telephone counseling and home blood pressure (BP) monitoring for 12 months. Findings support that the Self-Help Intervention Program on the Control of HBP was effective in controlling BP in this ethnic/linguistic minority population. The BP control rates for the intervention and control groups were 49.5% vs. 43.2% at baseline, 58.5% vs. 42.4% at 6 months, 67.9% vs. 52.5% at 12 months, and 54.3% vs. 53.0% at 18 months. Significant changes were observed over time in some psychobehavioral outcomes, including self-efficacy for BP control, medication adherence behavior, HBP knowledge, and depression. The study findings suggest that the multimodal Self-Help Intervention Program on the Control of HBP is effective at promoting optimal HBP control for this ethnic/linguistic minority population.

Margaret Macherera

2016-04-01

Full Text Available Community-based early warning systems involve community driven collection and analysis of information that enable warning messages to help a community to react to a hazard and reduce the resulting loss or harm. Most early warning systems are designed at the national or global level. Local communities’ capacity to predict weather conditions using indigenous knowledge has been demonstrated in studies focusing on climate change and agriculture in some African countries. This review was motivated by successes made in non-disease specific community-based early warning systems with a view to identify opportunities for developing similar systems for malaria. This article reviewed the existing community-based early warning systems documented in literature. The types of disasters that are addressed by these systems and the methodologies utilised in the development of the systems were identified. The review showed that most of the documented community-based early warning systems focus on natural disasters such as floods, drought, and landslides. Community-based early warning systems for human diseases are very few, even though such systems exist at national and regional and global levels. There is a clear gap in terms of community-based malaria early warning systems. The methodologies for the development of the community-based early warning systems reviewed mainly derive from the four elements of early warning systems; namely risk knowledge, monitoring, warning communication and response capability. The review indicated the need for the development of community based early warning systems for human diseases. Keywords: community; early warning; disaster; hazards

Parish nurses contribute to community health through the expertise and programming they provide to and through faith communities. Application of community-based participatory research (CBPR) principles helps develop, implement, and evaluate effective community interventions. University graduate students partnered with a Hospital Parish Nurse Program (HPNP) in an urban community to provide assessment data in a CBPR project that led the HPNP to focus resources and interventions on high obesity rates. The HPNP utilized data to write grant proposals to expand community services to impact obesity.

Detection of communities with Naming Game-based methods

Science.gov (United States)

Ribeiro, Carlos Henrique Costa

2017-01-01

Complex networks are often organized in groups or communities of agents that share the same features and/or functions, and this structural organization is built naturally with the formation of the system. In social networks, we argue that the dynamic of linguistic interactions of agreement among people can be a crucial factor in generating this community structure, given that sharing opinions with another person bounds them together, and disagreeing constantly would probably weaken the relationship. We present here a computational model of opinion exchange that uncovers the community structure of a network. Our aim is not to present a new community detection method proper, but to show how a model of social communication dynamics can reveal the (simple and overlapping) community structure in an emergent way. Our model is based on a standard Naming Game, but takes into consideration three social features: trust, uncertainty and opinion preference, that are built over time as agents communicate among themselves. We show that the separate addition of each social feature in the Naming Game results in gradual improvements with respect to community detection. In addition, the resulting uncertainty and trust values classify nodes and edges according to role and position in the network. Also, our model has shown a degree of accuracy both for non-overlapping and overlapping communities that are comparable with most algorithms specifically designed for topological community detection.

This study identifies fall risk factors in an understudied population of older people who receive community-based care services. Data were collected from enrollees of Ohio's Medicaid home- and community-based waiver program (preadmission screening system providing options and resources today [PASSPORT]). A total of 23,182 participants receiving PASSPORT services in 2005/2006 was classified as fallers and nonfallers, and a variety of risk factors for falling was analyzed using logistic regressions. The following factors were identified as risk factors for falling: previous fall history, older age, White race, incontinence, higher number of medications, fewer numbers of activity of daily living limitations, unsteady gait, tremor, grasping strength, and absence of supervision. Identifying risk factors for the participants of a Medicaid home- and community-based waiver program are useful for a fall risk assessment, but it would be most helpful if the community-based care service programs incorporate measurements of known fall risk factors into their regular data collection, if not already included.

Community energy planning is a vital component of successful energy resource development and project implementation. Planning can help tribes develop a shared vision and strategies to accomplish their energy goals. This paper explores the benefits of an asset-based approach to tribal community energy planning. While a framework for community energy planning and federal funding already exists, some areas of difficulty in the planning cycle have been identified. This paper focuses on developing a planning framework that offsets those challenges. The asset-based framework described here takes inventory of a tribe’s capital assets, such as: land capital, human capital, financial capital, and political capital. Such an analysis evaluates how being rich in a specific type of capital can offer a tribe unique advantages in implementing their energy vision. Finally, a tribal case study demonstrates the practical application of an asset-based framework.

From Help-Seekers to Influential Users: A Systematic Review of Participation Styles in Online Health Communities.

2015-12-01

Understanding how people participate in and contribute to online health communities (OHCs) is useful knowledge in multiple domains. It is helpful for community managers in developing strategies for building community, for organizations in disseminating information about health interventions, and for researchers in understanding the social dynamics of peer support. We sought to determine if any patterns were apparent in the nature of user participation across online health communities. The current study involved a systematic review of all studies that have investigated the nature of participation in an online health community and have provided a quantifiable method for categorizing a person based on their participation style. A systematic search yielded 20 papers. Participatory styles were classified as either multidimensional (based on multiple metrics) or unidimensional (based on one metric). With respect to the multidimensional category, a total of 41 different participation styles were identified ranging from Influential Users who were leaders on the board to Topic-Focused Responders who focused on a specific topic and tended to respond to rather than initiate posts. However, there was little overlap in participation styles identified both across OHCs for different health conditions and within OHCs for specific health conditions. Five of the 41 styles emerged in more than one study (Hubs, Authorities, Facilitators, Prime Givers, and Discussants), but the remainder were reported in only one study. The focus of the unidimensional studies was on level of engagement and particularly on high-engaged users. Eight different metrics were used to evaluate level of engagement with the greatest focus on frequency of posts. With the exception of high-engaged users based on high post frequency, the current review found little evidence for consistent participatory styles across different health communities. However, this area of research is in its infancy, with most of the

Learning from one another: evaluating the impact of horizontal knowledge exchange for environmental management and governance

Directory of Open Access Journals (Sweden)

Céline Tschirhart

2016-06-01

Full Text Available There is increasing advocacy for inclusive community-based approaches to environmental management, and growing evidence that involving communities improves the sustainability of social-ecological systems. Most community-based approaches rely on partnerships and knowledge exchange between communities, civil society organizations, and professionals such as practitioners and/or scientists. However, few models have actively integrated more horizontal knowledge exchange from community to community. We reflect on the transferability of community owned solutions between indigenous communities by exploring challenges and achievements of community peer-to-peer knowledge exchange as a way of empowering communities to face up to local environmental and social challenges. Using participatory visual methods, indigenous communities of the North Rupununi (Guyana identified and documented their community owned solutions through films and photostories. Indigenous researchers from this community then shared their solutions with six other communities that faced similar challenges within Guyana, Suriname, Venezuela, Colombia, French Guiana, and Brazil. They were supported by in-country civil society organizations and academics. We analyzed the impact of the knowledge exchange through interviews, field reports, and observations. Our results show that indigenous community members were significantly more receptive to solutions emerging from, and communicated by, other indigenous peoples, and that this approach was a significant motivating force for galvanizing communities to make changes in their community. We identified a range of enabling factors, such as building capacity for a shared conceptual and technical understanding, that strengthens the exchange between communities and contributes to a lasting impact. With national and international policy-makers mobilizing significant financial resources for biodiversity conservation and climate change mitigation, we argue

Agricultural fertilization significantly affects arbuscular mycorrhizal fungal (AMF) community composition. However, the functional implications of community shifts are unknown, limiting understanding of the role of AMF in agriculture. We assessed AMF community composition at four sites managed under the same nitrogen (N) and phosphorus (P) fertilizer regimes for 55 yr. We also established a glasshouse experiment with the same soils to investigate AMF-barley (Hordeum vulgare) nutrient exchange, using carbon ( 13 C) and 33 P isotopic labelling. N fertilization affected AMF community composition, reducing diversity; P had no effect. In the glasshouse, AMF contribution to plant P declined with P fertilization, but was unaffected by N. Barley C allocation to AMF also declined with P fertilization. As N fertilization increased, C allocation to AMF per unit of P exchanged increased. This occurred with and without P fertilization, and was concomitant with reduced barley biomass. AMF community composition showed no relationship with glasshouse experiment results. The results indicate that plants can reduce C allocation to AMF in response to P fertilization. Under N fertilization, plants allocate an increasing amount of C to AMF and receive relatively less P. This suggests an alteration in the terms of P-C exchange under N fertilization regardless of soil P status. © 2016 The Authors. New Phytologist © 2016 New Phytologist Trust.

2015-02-01

The purpose of the study is to explore African American men's perceptions of how community-based, community-health worker (CHW)-delivered diabetes interventions might best be implemented. Four 90-minute focus groups were guided by a trained moderator with a written guide to facilitate discussion on the topic of diabetes management and preferences for community-based programs. Participants were recruited from the diabetes education database at a safety-net health system in Jefferson County, AL. Two independent reviewers performed content analysis to identify major themes using an iterative, combined deductive and inductive approach. There were 25 male participants. Mean years living with diabetes was 9.6 (range, 1-20). Participants demonstrated knowledge of self-management strategies and identified various hardships including emotional and physical manifestations of diabetes, dietary restrictions, and institutional frustrations with the health system that contributed to self-management barriers. Their preferred CHW responsibilities were to educate, hold support groups, help track daily activities, and help find resources. Potential concerns included the need for confidentiality and fears of being stereotyped. Participants identified critical self-management strategies but endure hardships that present barriers to daily diabetes management. Preferences for community-based programs and suggested CHW responsibilities could help to overcome many of those barriers by increasing access and providing support. © 2014 The Author(s).

2015-01-01

In three-party password authenticated key exchange (AKE) protocol, since two users use their passwords to establish a secure session key over an insecure communication channel with the help of the trusted server, such a protocol may suffer the password guessing attacks and the server has to maintain the password table. To eliminate the shortages of password-based AKE protocol, very recently, according to chaotic maps, Lee et al. [2015 Nonlinear Dyn. 79 2485] proposed a first three-party-authenticated key exchange scheme without using passwords, and claimed its security by providing a well-organized BAN logic test. Unfortunately, their protocol cannot resist impersonation attack, which is demonstrated in the present paper. To overcome their security weakness, by using chaotic maps, we propose a biometrics-based anonymous three-party AKE protocol with the same advantages. Further, we use the pi calculus-based formal verification tool ProVerif to show that our AKE protocol achieves authentication, security and anonymity, and an acceptable efficiency. (paper)

Turkish Migrant Women with Recurrent Depression: Results from Community-based Self-help Groups.

2017-01-01

The study focuses on psychosocial functioning of female Turkish immigrants in Austria with recurrent depressive disorder participating in self-help groups. Self-help groups guided by group leaders of Turkish descent should increase autonomy in participants, providing the opportunity to follow their ethnic health beliefs. Turkish immigrant women (n = 43) with recurrent depressive disorder participated in self-help groups over four months. Qualitative data of participants and group leaders, containing interviews, group protocols and supervision protocols of group leaders were analyzed using the qualitative content analysis for effects on psychosocial function, such as interaction with others, illness beliefs and benefit from self-help group. Women reported feelings of being neglected and violated by their husbands. They stated that they had gained strength and had emancipated themselves from their husbands. Self-help groups functioned as social resources and support for changes in participants' lives. Further interventions should integrate the functional value of depressive symptoms and focus on social support systems and social networks.

Leveraging federal science data and tools to help communities & business build climate resilience

Science.gov (United States)

Herring, D.

2016-12-01

Decision-makers in every sector and region of the United States are seeking actionable science-based information to help them understand and manage their climate-related risks. Translating data, tools and information from the domain of climate science to the domains of municipal, social, and economic decision-making raises complex questions—e.g., how to communicate causes and impacts of climate variability and change; how to show projections of plausible future climate scenarios; how to characterize and quantify vulnerabilities, risks, and opportunities facing communities and businesses; and how to make and implement "win-win" adaptation plans. These are the types of challenges being addressed by a public-private partnership of federal agencies, academic institutions, non-governmental organizations, and private businesses that are contributing to the development of the U.S. Climate Resilience Toolkit (toolkit.climate.gov), a new website designed to help people build resilience to extreme events caused by both natural climate variability and long-term climate change. The site's Climate Explorer is designed to help people understand potential climate conditions over the course of this century. It offers easy access to downloadable maps, graphs, and data tables of observed and projected temperature, precipitation and other decision-relevant climate variables dating back to 1950 and out to 2100. Of course, climate change is only one of many variables affecting decisions about the future so the Toolkit also ties climate information to a wide range of other relevant tools and information to help users to explore their vulnerabilities and risks. In this session, we will describe recent enhancements to the Toolkit, lessons learned from user engagements, and evidence that our approach of coupling scientific information with actionable decision-making processes is helping Americans build resilience to climate-related impacts.

Fecal incontinence (FI) is a common debilitating disorder that tends to be underreported. Although low health literacy likely contributes to the underreporting, studies on FI knowledge among the general population remain scarce. We investigated how FI knowledge is associated with attitudes and help-seeking behaviors. We conducted a cross-sectional survey among community-dwelling adults undergoing national health screening in Korea. A structured, self-administered questionnaire was used to assess FI knowledge, attitudes, and help-seeking behaviors. Odds ratios (ORs; 95% confidence intervals, CIs) were estimated using logistic regression with adjustment for covariables. Of the 601 participants completing the survey, only 29.8% were aware of the term FI, and their knowledge levels were insufficient. As for FI-related attitudes, 24.6% considered FI to be very rare, and 22.3% considered it to be moderately or less distressing. Individuals who knew the term FI tended to consider FI more common (OR: 2.45; 95%CI: 1.49-4.02) and distressing (OR: 1.68; 95%CI: 1.07-2.63) than those without knowledge. Assuming future FI occurrence, those considering FI to be distressing were less willing to ignore or self-manage the condition (OR: 0.25; 95%CI: 0.11-0.58). Among patients with FI (n = 83), only 30.1% had sought help and 8.4% had consulted doctors. Knowing the term FI was significantly associated with overall help-seeking behavior (OR: 9.23; 95%CI: 2.09-40.77). FI knowledge levels and help-seeking rates were low among community-dwelling adults. FI knowledge was significantly associated with attitudes and help-seeking behaviors. Future public education programs are warranted to improve FI knowledge, attitudes, and help-seeking behaviors. © 2018 Wiley Periodicals, Inc.

2013-03-01

Full Text Available This research investigated the relationship between adolescent afterschool program attendance, self-esteem and feelings of community connectedness. Thirty-nine of the 61 at-risk adolescents enrolled in two federally funded, community based afterschool programs participated in the study. Participants completed a 10-item self-esteem questionnaire and a 5-item section of the Youth Involved in Community Issues Survey (YICI to measure perceptions of community connectedness. Attendance records were also collected from the sites. Data were analyzed using Pearson Correlations. Results indicated that there was not a significant relationship between the total variables. The individual item analysis, however, did find a significant relationship between adolescent community connectedness and self esteem items. Findings suggest that there is a relationship to be explored and strengthened through means of community outreach for adolescents. Conclusions from this study have important implications for youth practice. Specifically, program leaders need to help adolescents get involved in the community as contributing members.

An Integrated Model of Co-ordinated Community-Based Care.

2015-08-01

Co-ordinated approaches to community-based care are a central component of current and proposed efforts to help vulnerable older adults obtain needed services and supports and reduce unnecessary use of health care resources. This study examines ElderHelp Concierge Club, an integrated community-based care model that includes comprehensive personal and environmental assessment, multilevel care co-ordination, a mix of professional and volunteer service providers, and a capitated, income-adjusted fee model. Evaluation includes a retrospective study (n = 96) of service use and perceived program impact, and a prospective study (n = 21) of changes in participant physical and social well-being and health services utilization. Over the period of this study, participants showed greater mobility, greater ability to meet household needs, greater access to health care, reduced social isolation, reduced home hazards, fewer falls, and greater perceived ability to obtain assistance needed to age in place. This study provides preliminary evidence that an integrated multilevel care co-ordination approach may be an effective and efficient model for serving vulnerable community-based elders, especially low and moderate-income elders who otherwise could not afford the cost of care. The findings suggest the need for multisite controlled studies to more rigorously evaluate program impacts and the optimal mix of various program components. © The Author 2014.

2012-01-01

This article aims to describe continuous quality improvement (CQI) for substance abuse prevention and treatment programs in a community-based organization setting. CQI (e.g., plan-do-study-act cycles (PDSA)) applied in healthcare and industry was adapted for substance abuse prevention and treatment programs in a community setting. The authors assessed the resources needed, acceptability and CQI feasibility for ten programs by evaluating CQI training workshops with program staff and a series of three qualitative interviews over a nine-month implementation period with program participants. The CQI activities, PDSA cycle progress, effort, enthusiasm, benefits and challenges were examined. Results indicated that CQI was feasible and acceptable for community-based substance abuse prevention and treatment programs; however, some notable resource challenges remain. Future studies should examine CQI impact on service quality and intended program outcomes. The study was conducted on a small number of programs. It did not assess CQI impact on service quality and intended program outcomes. Practical implications- This project shows that it is feasible to adapt CQI techniques and processes for community-based programs substance abuse prevention and treatment programs. These techniques may help community-based program managers to improve service quality and achieve program outcomes. This is one of the first studies to adapt traditional CQI techniques for community-based settings delivering substance abuse prevention and treatment programs.

Estimating CO2 gas exchange in mixed age vegetable plant communities grown on soil-like substrates for life support systems

Science.gov (United States)

Velichko, V. V.; Tikhomirov, A. A.; Ushakova, S. A.

2018-02-01

If soil-like substrate (SLS) is to be used in human life support systems with a high degree of mass closure, the rate of its gas exchange as a compartment for mineralization of plant biomass should be understood. The purpose of this study was to compare variations in CO2 gas exchange of vegetable plant communities grown on the soil-like substrate using a number of plant age groups, which determined the so-called conveyor interval. Two experimental plant communities were grown as plant conveyors with different conveyor intervals. The first plant community consisted of conveyors with intervals of 7 days for carrot and beet and 14 days for chufa sedge. The conveyor intervals in the second plant community were 14 days for carrot and beet and 28 days for chufa sedge. This study showed that increasing the number of age groups in the conveyor and, thus, increasing the frequency of adding plant waste to the SLS, decreased the range of variations in CO2 concentration in the "plant-soil-like substrate" system. However, the resultant CO2 gas exchange was shifted towards CO2 release to the atmosphere of the plant community with short conveyor intervals. The duration of the conveyor interval did not significantly affect productivity and mineral composition of plants grown on the SLS.

AutoHelp is a case-based, Web-accessible help desk for users of the EOSDIS. Its uses a combination of advanced computer and Web technologies, knowledge-based systems tools, and cognitive engineering to offload the current, person-intensive, help desk facilities at the DAACs. As a case-based system, AutoHelp starts with an organized database of previous help requests (questions and answers) indexed by a hierarchical category structure that facilitates recognition by persons seeking assistance. As an initial proof-of-concept demonstration, a month of email help requests to the Goddard DAAC were analyzed and partially organized into help request cases. These cases were then categorized to create a preliminary case indexing system, or category structure. This category structure allows potential users to identify or recognize categories of questions, responses, and sample cases similar to their needs. Year one of this research project focused on the development of a technology demonstration. User assistance 'cases' are stored in an Oracle database in a combination of tables linking prototypical questions with responses and detailed examples from the email help requests analyzed to date. When a potential user accesses the AutoHelp system, a Web server provides a Java applet that displays the category structure of the help case base organized by the needs of previous users. When the user identifies or requests a particular type of assistance, the applet uses Java database connectivity (JDBC) software to access the database and extract the relevant cases. The demonstration will include an on-line presentation of how AutoHelp is currently structured. We will show how a user might request assistance via the Web interface and how the AutoHelp case base provides assistance. The presentation will describe the DAAC data collection, case definition, and organization to date, as well as the AutoHelp architecture. It will conclude with the year 2 proposal to more fully develop the

Electronic tools for health information exchange: an evidence-based analysis.

As patients experience transitions in care, there is a need to share information between care providers in an accurate and timely manner. With the push towards electronic medical records and other electronic tools (eTools) (and away from paper-based health records) for health information exchange, there remains uncertainty around the impact of eTools as a form of communication. To examine the impact of eTools for health information exchange in the context of care coordination for individuals with chronic disease in the community. A literature search was performed on April 26, 2012, using OVID MEDLINE, OVID MEDLINE In-Process and Other Non-Indexed Citations, OVID EMBASE, EBSCO Cumulative Index to Nursing & Allied Health Literature (CINAHL), the Wiley Cochrane Library, and the Centre for Reviews and Dissemination database, for studies published until April 26, 2012 (no start date limit was applied). A systematic literature search was conducted, and meta-analysis conducted where appropriate. Outcomes of interest fell into 4 categories: health services utilization, disease-specific clinical outcomes, process-of-care indicators, and measures of efficiency. The quality of the evidence was assessed individually for each outcome. Expert panels were assembled for stakeholder engagement and contextualization. Eleven articles were identified (4 randomized controlled trials and 7 observational studies). There was moderate quality evidence of a reduction in hospitalizations, hospital length of stay, and emergency department visits following the implementation of an electronically generated laboratory report with recommendations based on clinical guidelines. The evidence showed no difference in disease-specific outcomes; there was no evidence of a positive impact on process-of-care indicators or measures of efficiency. A limited body of research specifically examined eTools for health information exchange in the population and setting of interest. This evidence included a

2018-04-01

In this paper, we design a novel quantum secret information equal exchange protocol, which implements the equal exchange of secret information between the two parties with the help of semi-trusted third party (TP). In the protocol, EPR pairs prepared by the TP are, respectively, distributed to both the communication parties. Then, the two parties perform Pauli operation on each particle and return the new particles to TP, respectively. TP measures each new pair with Bell basis and announces the measurement results. Both parties deduce the secret information of each other according to the result of announcement by TP. Finally, the security analysis shows that this protocol solves the problem about equal exchange of secret information between two parties and verifies the security of semi-trusted TPs. It proves that the protocol can effectively resist glitch attacks, intercept retransmission attacks and entanglement attack.

2018-01-01

To describe the application of the Community-Based Collaborative Action Research (CBCAR) framework to uplift rural community voices while conducting a community health needs assessment (CHNA) by formulating a partnership between a critical access hospital, public health agency, school of nursing, and community members to improve societal health of this rural community. This prospective explorative study used the CBCAR framework in the design, collection, and analysis of the data. The framework phases include: Partnership, dialogue, pattern recognition, dialogue on meaning of pattern, insight into action, and reflecting on evolving pattern. Hospital and public health agency leaders learned how to use the CBCAR framework when conducting a CHNA to meet Affordable Care Act federal requirements. Closing the community engagement gap helped ensure all voices were heard, maximized intellectual capital, synergized efforts, improved communication by establishing trust, aligned resources with initiatives, and diminished power struggles regarding rural health. The CBCAR framework facilitated community engagement and promoted critical dialogue where community voices were heard. A sustainable community-based collaborative was formed. The project increased the critical access hospital's capacity to conduct a CHNA. The collaborative's decision-making capacity was challenged and ultimately strengthened as efforts continue to be made to address rural health.

How a Beacon Community Program in New Orleans Helped Create a Better Health Care System by Building Relationships before Technology.

Khurshid, Anjum; Brown, Lisanne

2014-01-01

In the aftermath of Hurricane Katrina, much of New Orleans' healthcare infrastructure was destroyed. Initial federal funding after the storm expanded primary care services and helped set up medical homes for New Orleans' large uninsured and underinsured population. Following that, the Beacon Community in New Orleans, charged with improving health care through the use of technology, decided the best way to accomplish those goals was to build community partnerships and introduce technology improvements based on their input and on their terms. The purpose of this paper is to describe how those partnerships were wrought, including the innovative use of a conceptual framework, and how they are being sustained; how different technologies were and are being introduced; and what the results have been so far. Past successful community experiences, as well as a proven conceptual framework, were used to help establish community partnerships and governance structures, as well as to demonstrate their linkages. This paper represents a compilation of reports and information from key Beacon leaders, staff and providers and their firsthand experiences in setting up those structures, as well as their conclusions. The community partnerships proved extremely successful in not only devising successful ways to introduce new technology into healthcare settings, but in sustaining those changes by creating a governance structure that has enough fluidity to adapt to changing circumstances. Building and developing community partnerships takes time and effort; however, these relationships are necessary and essential to introducing and sustaining new technologies in a healthcare setting and should be a first step for any organization looking to accomplish such goals.

Blockchain for Smart Grid Resilience: Exchanging Distributed Energy at Speed, Scale and Security

Energy Technology Data Exchange (ETDEWEB)

Mylrea, Michael E.; Gourisetti, Sri Nikhil Gup

2017-09-18

Blockchain may help solve several complex problems related to integrity and trustworthiness of rapid, distributed, complex energy transactions and data exchanges. In a move towards resilience, blockchain commoditizes trust and enables automated smart contracts to support auditable multiparty transactions based on predefined rules between distributed energy providers and customers. Blockchain based smart contracts also help remove the need to interact with third-parties, facilitating the adoption and monetization of distributed energy transactions and exchanges, both energy flows as well as financial transactions. This may help reduce transactive energy costs and increase the security and sustainability of distributed energy resource (DER) integration, helping to remove barriers to a more decentralized and resilient power grid.

Political pressures and exchange rate stability in emerging market economies

OpenAIRE

Ester Faia; Massimo Giuliodori; Michele Ruta

2008-01-01

This paper presents a political economy model of exchange rate policy. The theory is based on a common agency approach with rational expectations. Financial and exporter lobbies exert political pressures to influence the government’s choice of exchange rate policy, before shocks to the economy are realized. The model shows that political pressures affect exchange rate policy and create an over-commitment to exchange rate stability. This helps to rationalize the empirical evidence on fear of l...

Pre-school communication problems are common, with implications for school readiness and educational achievement. Help is available from a variety of community healthcare providers. This study examined the extent to which help is received, and the predictors of service receipt. Prospective community study, in Melbourne, Victoria. At age 4 years, we assessed the speech, receptive and expressive language and fluency of 1607 children and gave feedback to their parents. At age 5 years, 983 families provided data on service use for communication problems between and 4 and 5 years. We compared service use between participants with and without impairment, and used logistic regression to estimate the strength of association between potential predictors (gender, socio-economic status, maternal education, English-speaking background status, family history of speech and language problems and parent concern) and service use (binary outcome). Data were available for both communication status and service use for 753 children. Only 44.9% of the 196 children with communication impairment received help from a professional. Furthermore, 7% of the 557 that did not meet criteria for communication impairment nevertheless received help from a professional. Parent concern was the strongest predictor of service use (adjusted odds ratio = 9.0; 95% CI: 5.6-14.8). Both over- and under-servicing for communication problems were evident. This study shows that accessing help for communication problems requires more than simply informing parents about the problem and having services available; there is a need for systematic support to get the right children to services. © 2013 John Wiley & Sons Ltd.

We determined national levels of public participation in medical research study design. We compared public interest in medical research participation (MRP) in studies overall, versus studies explicitly designed with public involvement. Cross-sectional household survey of US population in June 2013. Descriptive statistics estimated participation in medical research study design. Chi-square test compared levels of interest in MRP if respondent knew patients or community members helped design the study. Of 2,048 respondents (participation rate 60%), 5% knew someone who had helped design a medical research study. There was no association between having known someone or personal participation in study design and willingness to engage in MRP. Although the overall proportion of respondents who would consider MRP initially (51%) was similar to the proportion who would consider MRP with community member involvement in study design (49%), the changes in respondents' views across the different scenarios were significantly greater than what would have been expected by chance. We found similar levels of interest in MRP whether or not the public is involved in medical research study design. This finding may indicate that public involvement in study design, like community-based participatory research, may not affect overall rates of MRP. © 2015 Wiley Periodicals, Inc.

Exchange-rate-based stabilization in Argentina and Chile : a fresh look

Exchange-rate-based stabilization is designed to reduce inflation by using the exchange rate as the main nominal anchor. This does not necessarily mean a fixed exchange rate. A crawling peg with a low rate of depreciation or a pre-announced gradual reduction in the rate of devaluation are alternative ways to use the exchange rate as a nominal anchor. Exchange-rate-based stabilization (ERBS) has been widely used in the high-inflation economies of Latin America. Argentina, Chile, and Uruguay ad...

Health-related hot topic detection in online communities using text clustering.

Directory of Open Access Journals (Sweden)

Yingjie Lu

Full Text Available Recently, health-related social media services, especially online health communities, have rapidly emerged. Patients with various health conditions participate in online health communities to share their experiences and exchange healthcare knowledge. Exploring hot topics in online health communities helps us better understand patients' needs and interest in health-related knowledge. However, the statistical topic analysis employed in previous studies is becoming impractical for processing the rapidly increasing amount of online data. Automatic topic detection based on document clustering is an alternative approach for extracting health-related hot topics in online communities. In addition to the keyword-based features used in traditional text clustering, we integrate medical domain-specific features to represent the messages posted in online health communities. Three disease discussion boards, including boards devoted to lung cancer, breast cancer and diabetes, from an online health community are used to test the effectiveness of topic detection. Experiment results demonstrate that health-related hot topics primarily include symptoms, examinations, drugs, procedures and complications. Further analysis reveals that there also exist some significant differences among the hot topics discussed on different types of disease discussion boards.

Any community can experience a disaster, and many traumatic events occur without warning. Psychologists can be an important resource assisting in psychological support for individuals and communities, in preparation for and in response to traumatic events. Disaster mental health and the community-based model of psychological first aid are described. The National Preparedness and Response Science Board has recommended that all mental health professionals be trained in disaster mental health, and that first responders, civic officials, emergency managers, and the general public be trained in community-based psychological first aid. Education and training resources in these two fields are described to assist psychologists and others in preparing themselves to assist their communities in difficult times and to help their communities learn to support one another. © 2016 Wiley Periodicals, Inc.

South-South exchanges enhance resource management and biodiversity conservation at various scales

Directory of Open Access Journals (Sweden)

William D Heyman

2011-01-01

Full Text Available International conservation organisations have invested considerable resources in fostering biodiversity conservation programs in the humid tropics, the most biologically diverse areas on earth. Recent approaches to conservation have centered on integrated conservation and development projects and participatory resource management programs, co-managed between governments and local communities. But these programs have had only mixed success and often suffer from insufficient quantity or quality of participation by local communities. We pose that participatory resource management is more likely to succeed when community members, 1 gain a global perspective on how their social, economic and environmental conditions compare with peer communities in other similar areas of the world, and thus better understand issues of relative scarcity and the benefits of sustainable resource management, and 2 engage as decision-makers at every stage of the conservation process up to reflective program evaluation. This paper examines the role of South-South exchanges as a tool to achieve these intermediate goals that ultimately foster more effective and participatory conservation and support sustainable local livelihoods. The data are extracted from the initiatives of the authors in two different environments- marine and coastal communities in Central America and the Caribbean, and lowland rainforest communities in the western Amazon of South America. We conclude that the exchanges are effective ways to build stakeholder comprehension about, and meaningful engagement in, resource management. South-South exchanges may also help build multi-local coalitions from various remote areas that together support biodiversity conservation at regional and global scales.

Full Text Available The aim of this study is to investigate the impact of exchange rate fluctuation on economic growth in Nigeria within the context of four profound theories: purchasing power parity; monetary model of exchange rates; the portfolio balance approach; and the optimal currency area theory. Data was collected from the CBN statistical bulletin in Nigeria from 2003– 2013and the Autoregressive Distributed Lag (ARDL model was employed to estimate the model. In the model, real GDP (RGDP was used as the proxy for economic growth while Inflation rate (IF, Exchange rate (EXC, Interest rate (INT and Money Supply(M2 as proxies for other macroeconomic variables. The empirical results show that exchange rate fluctuation has no effect on economic growth in the long run though a short run relationship exist between the two. Based on these findings, this paper recommends that the Central bank for policy purposes should ensure that stern foreign exchange control policies are put in place in order to help in appropriate determination of the value of the exchange rate. This will in the long run help to strengthen the value of the Naira.

A protocol that allows any two entities to negotiate a shared session key is commonly called a key exchange protocol. If the protocol provides a function to authenticate each other, we call the protocol authenticated key exchange protocol (AKE). Password authentication key exchange (PAKE) is the AKE protocol in which the two entities share a humanmemorable password. Most of current PAKE relies on the existence of a public key infrastructure, which sometime is impossible for a certain environments such as low computational device due to the computation overhead. In this paper, we propose password-based authenticated key exchange using smart card. Compared to previous PAKE, our protocol is more efficient because our protocol is based on ECC. Thereby, the proposed protocol can be well applied to low computation device.

2013-01-01

Substantial resources are being invested in health information exchanges (HIE), community-based consortia that enable independent health-care organizations to exchange clinical data. However, under pressure to form accountable care organizations, medical groups may merge and support private HIE, reducing the potential utility of community HIEs. Simulations of “care transitions” based on data from 10 Massachusetts communities suggest that mergers would have to be considerable to substantially reduce the potential utility of an HIE. Nonetheless, simulations also suggest that HIEs will need to recruit a large proportion of the medical groups in a community, as hospitals and the largest groups account for only 10 to 20% of care transitions in communities.

Bassi, Sherry

2011-01-01

Service-learning (SL) is an experiential teaching method that combines instruction with community service, with the aim of enriching students' academic learning, interpersonal skills and sense of responsibility while making meaningful contributions to the community. However, measuring outcomes of service-learning projects is difficult. This article reports on the perceptions of 18 third-year undergraduate nursing students who took part in a pilot service-learning project targeting tobacco use in a local elementary school. Faculty members evaluated the program's outcomes by engaging students in structured reflection on the program about its relevance to their future careers as practicing professionals, especially in community-based settings. The students' perceptions were elicited through three sets of reflective assignments following the project. Findings from the reflective assignments suggest that the pilot program was successful in enhancing the students' academic, social, and personal development while building a partnership between the school of nursing and key players in the community, including school-based nurses, teachers, administrators, families, and community leaders. The author suggests that service-learning projects can help nursing students accomplish key developmental tasks of the college years (such as building their competence, autonomy, and integrity), while helping impart the skills and values they will need as they graduate and seek professional nursing roles.

Murtinho, Felipe; Eakin, Hallie; López-Carr, David; Hayes, Tanya M.

2013-11-01

Despite debate regarding whether, and in what form, communities need external support for adaptation to environmental change, few studies have examined how external funding impacts adaptation decisions in rural resource-dependent communities. In this article, we use quantitative and qualitative methods to assess how different funding sources influence the initiative to adapt to water scarcity in the Colombian Andes. We compare efforts to adapt to water scarcity in 111 rural Andean communities with varied dependence on external funding for water management activities. Findings suggest that despite efforts to use their own internal resources, communities often need external support to finance adaptation strategies. However, not all external financial support positively impacts a community’s abilities to adapt. Results show the importance of community-driven requests for external support. In cases where external support was unsolicited, the results show a decline, or “crowding-out,” in community efforts to adapt. In contrast, in cases where communities initiated the request for external support to fund their own projects, findings show that external intervention is more likely to enhance or “crowds-in” community-driven adaptation.

Advances in Internet technology now enable unprecedented global collaboration and collective knowledge exchange. Up to this time, there have been limited efforts to use these technologies to actively promote knowledge exchange across the global pediatric critical care community. To develop an open-access, peer-reviewed, not-for-profit Internet-based learning application, OPENPediatrics, a collaborative effort with the World Federation of Pediatric Intensive and Critical Care Societies, was designed to promote postgraduate educational knowledge exchange for physicians, nurses, and others caring for critically ill children worldwide. Description of program development. International multicenter tertiary pediatric critical care units across six continents. Multidisciplinary pediatric critical care providers. A software application, providing information on demand, curricular pathways, and videoconferencing, downloaded to a local computer. In 2010, a survey assessing postgraduate educational needs was distributed through World Federation of Pediatric Intensive and Critical Care Societies to constituent societies. Four hundred and twenty-nine critical care providers from 49 countries responded to the single e-mail survey request. Respondents included 68% physicians and 28% nurses who care for critically ill children. Fifty-two percent of respondents reported accessing the Internet at least weekly to obtain professional educational information. The five highest requests were for educational content on respiratory care [mechanical ventilation] (48% [38%]), sepsis (28%), neurology (25%), cardiology (14%), extracorporeal membrane oxygenation (10%), and ethics (8%). Based on these findings, and in collaboration with researchers in adult learning and online courseware, an application was developed and is currently being used by 770 registered users in 60 countries. We describe here the development and implementation of an Internet-based application which is among the first

Novel silica-based ion exchange resin

Energy Technology Data Exchange (ETDEWEB)

NONE

1997-11-01

Eichrom`s highly successful Diphonixo resin resembles a conventional ion exchange resin in its use of sulfonic acid ligands on a styrene- divinylbenzene matrix. Diphonix resin exhibits rapid exchange kinetics that allow economical operation of ion exchange systems. Unlike conventional resins, Diphonix resin contains chelating ligands that are diphosphonic acid groups that recognize and remove the targeted metals and reject the more common elements such as sodium, calcium and magnesium. This latter property makes Diphonix ideal for many industrial scale applications, including those involving waste treatment. For treatment of low-level, transuranic (TRU) and high- level radioactive wastes, Diphonix`s polystyrene backbone hinders its application due to radiolytic stability of the carbon-hydrogen bonds and lack of compatibility with expected vitrification schemes. Polystyrene-based Diphonix is approximately 60% carbon- hydrogen. In response to an identified need within the Department of Energy for a resin with the positive attributes of Diphonix that also exhibits greater radiolytic stability and final waste form compatibility, Eichrom has successfully developed a new, silica-based resin version of Diphonix. Target application for this new resin is for use in environmental restoration and waste management situations involving the processing of low-level, transuranic and high-level radioactive wastes. The resin can also be used for processing liquid mixed waste (waste that contains low level radioactivity and hazardous constituents) including mixed wastes contaminated with organic compounds. Silica-based Diphonix is only 10% carbon-hydrogen, with the bulk of the matrix silica.

Obesity is the single biggest public health threat to developed and developing economies. In concert with healthy public policy, multi-strategy, multi-level community-based initiatives appear promising in preventing obesity, with several countries trialling this approach. In Australia, multiple levels of government have funded and facilitated a range of community-based obesity prevention initiatives (CBI), heterogeneous in their funding, timing, target audience and structure. This paper aims to present a central repository of CBI operating in Australia during 2013, to facilitate knowledge exchange and shared opportunities for learning, and to guide professional development towards best practice for CBI practitioners. A comprehensive search of government, non-government and community websites was undertaken to identify CBI in Australia in 2013. This was supplemented with data drawn from available reports, personal communication and key informant interviews. The data was translated into an interactive map for use by preventive health practitioners and other parties. We identified 259 CBI; with the majority (84%) having a dual focus on physical activity and healthy eating. Few initiatives, (n=37) adopted a four-pronged multi-strategy approach implementing policy, built environment, social marketing and/or partnership building. This comprehensive overview of Australian CBI has the potential to facilitate engagement and collaboration through knowledge exchange and information sharing amongst CBI practitioners, funders, communities and researchers. An enhanced understanding of current practice highlights areas of strengths and opportunities for improvement to maximise the impact of obesity prevention initiatives. © 2015 Public Health Association of Australia.

Help-seeking behaviour among people living with chronic hip or knee pain in the community

2009-12-01

Full Text Available Abstract Background A large proportion of people living with hip or knee pain do not consult health care professionals. Pain severity is often believed to be the main reason for help seeking in this population; however the evidence for this is contradictory. This study explores the importance of several potential risk factors on help seeking across different practitioner groups, among adults living with chronic hip or knee pain in a large community sample. Methods Health care utilization, defined as having seen a family doctor (GP during the past 12 months; or an allied health professional (AHP or alternative therapist during the past 3 months, was assessed in a community based sample aged 35 or over and reporting pain in hip or knee. Adjusted odds ratios were determined for social deprivation, rurality, pain severity, mobility, anxiety/depression, co-morbidities, and body mass index. Results Of 1119 persons reporting hip or knee pain, 52% had pain in both sites. Twenty-five percent of them had seen a doctor only, 3% an AHP only, and 4% an alternative therapist only. Thirteen percent had seen more than one category of health care professionals, and 55% had not seen any health care professional. In the multivariate model, factors associated with consulting a GP were mobility problems (OR 2.62 (1.64-4.17, urban living (OR 2.40 (1.14-5.04 and pain severity (1.28 (1.13-1.44.

A Range-Based Multivariate Model for Exchange Rate Volatility

OpenAIRE

Tims, Ben; Mahieu, Ronald

2003-01-01

textabstractIn this paper we present a parsimonious multivariate model for exchange rate volatilities based on logarithmic high-low ranges of daily exchange rates. The multivariate stochastic volatility model divides the log range of each exchange rate into two independent latent factors, which are interpreted as the underlying currency specific components. Due to the normality of logarithmic volatilities the model can be estimated conveniently with standard Kalman filter techniques. Our resu...

Verifier-based three-party authentication schemes using extended chaotic maps for data exchange in telecare medicine information systems.

2014-12-01

Telecare medicine information systems provide a communicating platform for accessing remote medical resources through public networks, and help health care workers and medical personnel to rapidly making correct clinical decisions and treatments. An authentication scheme for data exchange in telecare medicine information systems enables legal users in hospitals and medical institutes to establish a secure channel and exchange electronic medical records or electronic health records securely and efficiently. This investigation develops an efficient and secure verified-based three-party authentication scheme by using extended chaotic maps for data exchange in telecare medicine information systems. The proposed scheme does not require server's public keys and avoids time-consuming modular exponential computations and scalar multiplications on elliptic curve used in previous related approaches. Additionally, the proposed scheme is proven secure in the random oracle model, and realizes the lower bounds of messages and rounds in communications. Compared to related verified-based approaches, the proposed scheme not only possesses higher security, but also has lower computational cost and fewer transmissions.

Energy Information Augmented Community-Based Energy Reduction

Directory of Open Access Journals (Sweden)

Mark Rembert

2012-06-01

Full Text Available More than one-half of all U.S. states have instituted energy efficiency mandates requiring utilities to reduce energy use. To achieve these goals, utilities have been permitted rate structures to help them incentivize energy reduction projects. This strategy is proving to be only modestly successful in stemming energy consumption growth. By the same token, community energy reduction programs have achieved moderate to very significant energy reduction. The research described here offers an important tool to strengthen the community energy reduction efforts—by providing such efforts energy information tailored to the energy use patterns of each building occupant. The information provided most importantly helps each individual energy customer understand their potential for energy savings and what reduction measures are most important to them. This information can be leveraged by the leading community organization to prompt greater action in its community. A number of case studies of this model are shown. Early results are promising.

Full Text Available The Marine Fishery Resources Management Project (MFRMP hopes to facilitate partnership between the local government unit and the local communities in managing the coastal resources of Bolinao. Mobilization, both at the community and municipal levels, has been very important in promoting community-based strategies in coastal resources management. The community organization process in the municipality has gone through several levels; and different organizations have been formed. In empowering individuals and organizations, strategies tend to be varied and fluid depending on the need, the reason for mobilization, and the resources at hand. The Bolinao experience showcases different strategies used in implementing the resource enhancement, coastal zoning, harvest regulation, and capability building components of the program. These have included the formation of people's organizations, the mobilization of zonal action teams for each of the four zones, the creation and orientation of fishery and aquatic resources management councils at the barangay and municipal levels, and the active collaboration with the local government unit. These strategies and approaches have provided the people and the communities a wealth of experience and lessons that provide helpful insights in undertaking different endeavors. The strategies employed in the mobilization activities have significantly contributed to the empowerment of communities and individuals who are the primary managers of their resources.

Olney, Cynthia A

2005-10-01

After arguing that most community-based organizations (CBOs) function as complex adaptive systems, this white paper describes the evaluation goals, questions, indicators, and methods most important at different stages of community-based health information outreach. This paper presents the basic characteristics of complex adaptive systems and argues that the typical CBO can be considered this type of system. It then presents evaluation as a tool for helping outreach teams adapt their outreach efforts to the CBO environment and thus maximize success. Finally, it describes the goals, questions, indicators, and methods most important or helpful at each stage of evaluation (community assessment, needs assessment and planning, process evaluation, and outcomes assessment). Literature from complex adaptive systems as applied to health care, business, and evaluation settings is presented. Evaluation models and applications, particularly those based on participatory approaches, are presented as methods for maximizing the effectiveness of evaluation in dynamic CBO environments. If one accepts that CBOs function as complex adaptive systems-characterized by dynamic relationships among many agents, influences, and forces-then effective evaluation at the stages of community assessment, needs assessment and planning, process evaluation, and outcomes assessment is critical to outreach success.

Full Text Available Carina Wattmo, Elisabeth Paulsson, Lennart Minthon, Elisabet LondosClinical Memory Research Unit, Department of Clinical Sciences, Malmö, Lund University, Malmö, SwedenBackground: To investigate the long-term effects of cholinesterase inhibitor (ChEI therapy and the influence of sociodemographic and clinical factors on the use of community-based home help services (HHS by patients with Alzheimer’s disease (AD.Methods: This 3-year, prospective, multicenter study included 880 AD patients treated with donepezil, rivastigmine, or galantamine in a routine clinical setting. At baseline and every 6 months, the patients were assessed with several rating scales, including the Mini-Mental State Examination, Instrumental Activities of Daily Living (IADL, and Physical Self-Maintenance Scale. Doses of ChEI and amounts of HHS per week were recorded. Cox regression models were used to predict the time to HHS, and multiple linear regression was used to predict the volume of HHS used.Results: During the study, 332 patients (38% used HHS. Factors that both postponed HHS use and predicted lower amounts of HHS were higher doses of ChEIs, better IADL ability, and living with family. Men, younger individuals, and those with a slower IADL decline showed a longer time to HHS, whereas female sex, a lower cognitive status, or more medications at baseline predicted fewer hours of HHS.Conclusions: Higher doses of ChEI might reduce the use of HHS, possibly reducing the costs of community-based care. Female spouses provide more informal care than do male spouses, so the likelihood of using HHS is greater among women with AD. The "silent group" of more cognitively impaired and frail elderly AD patients receives less HHS, which might precipitate institutionalization.Keywords: cognition, activities of daily living, treatment effect, gender, predictors

Microscopic theory of the Coulomb based exchange coupling in magnetic tunnel junctions.

Udalov, O G; Beloborodov, I S

2017-05-04

We study interlayer exchange coupling based on the many-body Coulomb interaction between conduction electrons in magnetic tunnel junction. This mechanism complements the known interaction between magnetic layers based on virtual electron hopping (or spin currents). We find that these two mechanisms have different behavior on system parameters. The Coulomb based coupling may exceed the hopping based exchange. We show that the Coulomb based exchange interaction, in contrast to the hopping based coupling, depends strongly on the dielectric constant of the insulating layer. The dependence of the interlayer exchange interaction on the dielectric properties of the insulating layer in magnetic tunnel junction is similar to magneto-electric effect where electric and magnetic degrees of freedom are coupled. We calculate the interlayer coupling as a function of temperature and electric field for magnetic tunnel junction with ferroelectric layer and show that the exchange interaction between magnetic leads has a sharp decrease in the vicinity of the ferroelectric phase transition and varies strongly with external electric field.

Full Text Available Community-based responses have a lengthy history. The ravages of HIV on family functioning has included a widespread community response. Although much funding has been invested in front line community-based organisations (CBO, there was no equal investment in evaluations. This study was set up to compare children aged 9-13 years old, randomly sampled from two South African provinces, who had not received CBO support over time (YC with a group of similarly aged children who were CBO attenders (CCC. YC baseline refusal rate was 2.5% and retention rate was 97%. CCC baseline refusal rate was 0.7% and retention rate was 86.5%. 1848 children were included-446 CBO attenders compared to 1402 9-13 year olds drawn from a random sample of high-HIV prevalence areas. Data were gathered at baseline and 12-15 months follow-up. Standardised measures recorded demographics, violence and abuse, mental health, social and educational factors. Multivariate regression analyses revealed that children attending CBOs had lower odds of experiencing weekly domestic conflict between adults in their home (OR 0.17; 95% CI 0.09, 0.32, domestic violence (OR 0.22; 95% CI 0.08, 0.62, or abuse (OR 0.11; 95% CI 0.05, 0.25 at follow-up compared to participants without CBO contact.

In addition, CBO contact was associated with more prosocial behaviours at follow-up (B = 1.40; 95% CI 1.13, 1.67. No associations were observed between CBO contact and parental praise or post-traumatic symptoms. These results suggest that CBO exposure is associated with behavioural and mental health benefits for children over time. More severe psychopathology was not affected by attendance and

From science to action: Principles for undertaking environmental research that enables knowledge exchange and evidence-based decision-making.

Effective conservation requires knowledge exchange among scientists and decision-makers to enable learning and support evidence-based decision-making. Efforts to improve knowledge exchange have been hindered by a paucity of empirically-grounded guidance to help scientists and practitioners design and implement research programs that actively facilitate knowledge exchange. To address this, we evaluated the Ningaloo Research Program (NRP), which was designed to generate new scientific knowledge to support evidence-based decisions about the management of the Ningaloo Marine Park in north-western Australia. Specifically, we evaluated (1) outcomes of the NRP, including the extent to which new knowledge informed management decisions; (2) the barriers that prevented knowledge exchange among scientists and managers; (3) the key requirements for improving knowledge exchange processes in the future; and (4) the core capacities that are required to support knowledge exchange processes. While the NRP generated expansive and multidisciplinary science outputs directly relevant to the management of the Ningaloo Marine Park, decision-makers are largely unaware of this knowledge and little has been integrated into decision-making processes. A range of barriers prevented efficient and effective knowledge exchange among scientists and decision-makers including cultural differences among the groups, institutional barriers within decision-making agencies, scientific outputs that were not translated for decision-makers and poor alignment between research design and actual knowledge needs. We identify a set of principles to be implemented routinely as part of any applied research program, including; (i) stakeholder mapping prior to the commencement of research programs to identify all stakeholders, (ii) research questions to be co-developed with stakeholders, (iii) implementation of participatory research approaches, (iv) use of a knowledge broker, and (v) tailored knowledge management

Cervical cancer is a preventable disease which causes significant morbidity and mortality, particularly in developing countries. Although technology for early detection continues to improve, prevention programs suffer from significant barriers. Community-based participatory research is an approach to research which focuses on collaboration with the community to surmount these barriers. The objective of this study was to evaluate the utility of community-based participatory research techniques in a mother-child screen/treat and vaccinate program for cervical cancer prevention in Manchay, Peru. Human papillomavirus (HPV) self-sampling and cryotherapy were used for the screen/treat intervention, and the Gardasil vaccine was used for the vaccine intervention. Community health workers from Manchay participated in a 3-day educational course, designed by the research team. The community health workers then decided how to implement the interventions in their community. The success of the program was measured by (1) the ability of the community health workers to determine an implementation plan, (2) the successful use of research forms provided, (3) participation and retention rates, and (4) satisfaction of the participants. (1) The community health workers used a door-to-door approach through which participants were successfully registered and both interventions were successfully carried out; (2) registration forms, consent forms, and result forms were used correctly with minimal error; (3) screen/treat intervention: 97% of registered participants gave an HPV sample, 94% of HPV-positive women were treated, and 90% returned for 6-month follow-up; vaccine intervention: 95% of registered girls received the first vaccine, 97% of those received the second vaccine, and 93% the third; (4) 96% of participants in the screen/treat intervention reported high satisfaction. Community-based participatory research techniques successfully helped to implement a screen/treat and vaccinate

Abstract Objective: Obesity is the single biggest public health threat to developed and developing economies. In concert with healthy public policy, multi-strategy, multi-level community-based initiatives appear promising in preventing obesity, with several countries trialling this approach. In Australia, multiple levels of government have funded and facilitated a range of community-based obesity prevention initiatives (CBI), heterogeneous in their funding, timing, target audience and structure. This paper aims to present a central repository of CBI operating in Australia during 2013, to facilitate knowledge exchange and shared opportunities for learning, and to guide professional development towards best practice for CBI practitioners. Methods: A comprehensive search of government, non-government and community websites was undertaken to identify CBI in Australia in 2013. This was supplemented with data drawn from available reports, personal communication and key informant interviews. The data was translated into an interactive map for use by preventive health practitioners and other parties. Results: We identified 259 CBI; with the majority (84%) having a dual focus on physical activity and healthy eating. Few initiatives, (n=37) adopted a four-pronged multi-strategy approach implementing policy, built environment, social marketing and/or partnership building. Conclusion: This comprehensive overview of Australian CBI has the potential to facilitate engagement and collaboration through knowledge exchange and information sharing amongst CBI practitioners, funders, communities and researchers. Implications: An enhanced understanding of current practice highlights areas of strengths and opportunities for improvement to maximise the impact of obesity prevention initiatives. PMID:25561083

A Framework Applied Three Ways: Responsive Methods of Co-Developing and Implementing Community Science Solutions for Local Impact

While one-size-fits all may work for most hats, it rarely does for communities. Research products, methods and knowledge may be usable at a local scale, but applying them often presents a challenge due to issues like availability, accessibility, awareness, lack of trust, and time. However, in an environment with diminishing federal investment in issues related climate change, natural hazards, and natural resource use and management, the ability of communities to access and leverage science has never been more urgent. Established, yet responsive frameworks and methods can help scientists and communities work together to identify and address specific challenges and leverage science to make a local impact. Through the launch of over 50 community science projects since 2013, the Thriving Earth Exchange (TEX) has created a living framework consisting of a set of milestones by which teams of scientists and community leaders navigate the challenges of working together. Central to the framework are context, trust, project planning and refinement, relationship management and community impact. We find that careful and respectful partnership management results in trust and an open exchange of information. Community science partnerships grounded in local priorities result in the development and exchange of stronger decision-relevant tools, resources and knowledge. This presentation will explore three methods TEX uses to apply its framework to community science partnerships: cohort-based collaboration, online dialogues, and one-on-one consultation. The choice of method should be responsive to a community's needs and working style. For example, a community may require customized support, desire the input and support of peers, or require consultation with multiple experts before deciding on a course of action. Knowing and applying the method of engagement best suited to achieve the community's objectives will ensure that the science is most effectively translated and applied.

Isotope exchange reaction of tritium on precious metal catalyst based on cation-exchanged mordenite for blanket tritium recovery

Highlights: • Precious metal catalyst based on cation-exchanged mordenite was prepared. • Isotope exchange reaction between H{sub 2} and HTO on the catalyst was investigated. • The order of entire reaction is not clear, but it is the first-order reaction as for HTO. • Effect of exchanged cation may appear as the difference of the surface area of catalyst. - Abstract: It is known that the chemical forms of tritium released from a ceramic breeder blanket are hydrogen form and water form. To recover tritiated water vapor, adoption of dryer that is packed column of synthetic zeolite has been proposed. On the other hand, synthetic zeolite is often used as a support of precious metal catalyst. Such catalysts usually have a capability of hydrogen isotope exchange between gas and water vapor. If this catalyst is used to dryer, the dryer may obtain a preferable function for tritium recovery by isotopic exchange reaction. To assess such functions, reaction rate should be estimated. The results of water adsorption experiment on cation-exchanged mordenite-type zeolite suggested the possibility that state of adsorbed water varied by exchanged cation. So, in this work, precious metal catalyst based on cation-exchanged mordenite was prepared, and the reaction rate of chemical exchange between hydrogen and tritiated water was investigated under temperature range between 30 °C and 80 °C by the steady-state approximation. In the case of platinum on Na-mordenite, the reaction between gaseous hydrogen and tritiated water vapor was almost expressed as first-order reaction concerning tritiated water vapor concentration.

Using Analysis of Governance to Unpack Community-Based Conservation: A Case Study from Tanzania.

Robinson, Lance W; Makupa, Enock

2015-11-01

Community-based conservation policies and programs are often hollow with little real devolution. But to pass a judgment of community-based or not community-based on such initiatives and programs obscures what is actually a suite of attributes. In this paper, we analyze governance around a specific case of what is nominally community-based conservation-Ikona Wildlife Management Area (WMA) in Tanzania-using two complementary sets of criteria. The first relates to governance "powers": planning powers, regulatory powers, spending powers, revenue-generating powers, and the power to enter into agreements. The second set of criteria derive from the understanding of governance as a set of social functions: social coordination, shaping power, setting direction, and building community. The analysis helps to detail ways in which the Tanzanian state through policy and regulations has constrained the potential for Ikona WMA to empower communities and community actors. Although it has some features of community-based conservation, community input into how the governance social functions would be carried out in the WMA was constrained from the start and is now largely out of community hands. The two governance powers that have any significant community-based flavor-spending powers and revenue-generating powers-relate to the WMA's tourism activities, but even here the picture is equivocal at best. The unpacking of governance that we have done, however, reveals that community empowerment through the processes associated with creating and recognizing indigenous and community-conserved areas is something that can be pursued through multiple channels, some of which might be more strategic than others.

Couples with Intimate Partner Violence Seeking Relationship Help: Associations and Implications for Self-Help and Online Interventions.

2017-04-20

In-person conjoint treatments for relationship distress are effective at increasing relationship satisfaction, and newly developed online programs are showing promising results. However, couples reporting even low levels intimate partner violence (IPV) are traditionally excluded from these interventions. To improve the availability of couple-based treatment for couples with IPV, the present study sought to determine whether associations with IPV found in community samples generalized to couples seeking help for their relationship and whether web-based interventions for relationship distressed worked equally well for couples with IPV. In the first aim, in a sample of 2,797 individuals who were seeking online help for their relationship, the levels and correlates of both low-intensity and clinically significant IPV largely matched what is found in community samples. In the second aim, in a sample of 300 couples who were randomly assigned to a web-based intervention or a waitlist control group, low-impact IPV did not moderate the effects of the intervention for relationship distress. Therefore, web-based interventions may be an effective (and easily accessible) intervention for relationship distress for couples with low-intensity IPV. © 2017 Family Process Institute.

Do Community-based Institutions Build Resilience to Climate Change in Mongolia?

Science.gov (United States)

Fernandez-Gimenez, M.

2012-12-01

Climate change impacts are inherently local, yet relatively little is known about the role of local people and institutions in adapting to climate change. Mongolia has experienced one of the strongest warming trends on Earth over the past 40 years, associated declines in streamflow, and increases in the frequency of extreme winter weather events. Environmental changes are compounded by rapid political, economic and social transformations beginning in 1990. We investigate the complex interactions of social, ecological and climate changes across multiple levels from local to regional to national. We hypothesize that community-based institutions increase resilience by strengthening self-regulating feedbacks between social and ecological systems through development and enforcement of formal management rules, implementation of innovative management practices, strengthening of social networks and information exchange within and across levels of social organization, and enhanced monitoring. These result in better ecological and socio-economic conditions and greater adaptive capacity in areas under formal community-based management compared to adjacent areas without formal community management institutions. Evaluation of this hypothesis involves integrated collection and analysis of quantitative and qualitative ecological, social and hydro-climatic data at household, community and regional levels of spatial and social organization. Here, we present preliminary results evaluating these hypotheses from 10 counties (soum) in 3 provinces (aimag) in the Gobi desert-steppe of southern Mongolia based on household-level social data and plot-level ecological data representing. Our initial findings support the hypothesis that community-based institutions are associated with greater household adaptive capacity and healthier pasture ecological conditions, characterized by greater perennial vegetation cover and biomass, especially in the functional group most important for livestock

Theoretical details about optics and photonics are not common knowledge nowadays. Physicists are keen to scientifically explain `light,' which has a huge impact on our lives. It is necessary to examine it from multiple perspectives and to make the knowledge accessible to the public in an interdisciplinary, scientifically well-grounded and appealing medial way. To allow an information exchange on a global scale, our project "Invisible Light" establishes a worldwide accessible platform. Its contents will not be created by a single instance, but user-generated, with the help of the global community. The article describes the infotainment portal "Invisible Light," which stores scientific articles about light and photonics and makes them accessible worldwide. All articles are tagged with geo-coordinates, so they can be clearly identified and localized. A smartphone application is used for visualization, transmitting the information to users in real time by means of an augmented reality application. Scientific information is made accessible for a broad audience and in an attractive manner.

Because it is designed to promote and validate joint methods of discovery and community-based sources of knowledge, community-based management research has several unique characteristics, which may affect its execution. This article describes the process of a community-based management research project which is descriptive in nature and uses quantitative techniques to examine school efficiencies in low-income communities in a developing country – Bolivia. The article describes the partnership between a US-based university and a Bolivian not-for-profit organisation, the research context and the history of the research project, including its various phases. It focuses on the (yet unpublished process of the community-based research as opposed to its content (which has been published elsewhere. The article also makes the case that the robust partnership between the US-based university and the Bolivian NGO has been a determining factor in achieving positive results. Strengths and limitations are examined in the hope that the experience may be helpful to others conducting descriptive quantitative management research using community-engaged frameworks in cross-cultural settings. Keywords: international partnership, community-engaged scholarship, education efficiency, multicultural low-income education.

The objective of this study was to change the anthropometric, clinical, biochemical indicators and the rate of metabolic syndrome among obese adults in community. Obesity is an indicator of metabolic syndrome and cardiometabolic diseases. Obesity increases national health care expenditure in Taiwan. The high prevalence of obesity is not only a public health issue but also an economic problem. Changes in lifestyle can help to prevent metabolic syndrome for individuals with obesity. A randomised controlled trial was applied. In this randomised controlled trial by location, 136 metabolically abnormal obese individuals were included. The related indicators with metabolic syndrome were measured at baseline and after six months. The experimental group participated in a six-month community-based programme including provided exercise environments, exercise skills and volunteers' reminding. The control group was only provided environment and skills. One hundred and thirty-one participants completed this trail. In comparison with the baseline, the intervention group showed a significant increase in high-density lipoprotein cholesterol (2·34 mg/dl), and decrease in body weight (1·09 kg), waist circumference (3·63 cm), systolic blood pressure (10·52 mmHg), diastolic blood pressure (5·21 mmHg), fasting blood glucose (5·84 mg/dl) and body mass index (0·74 kg/m(2) ). In the control group, significant decrease in body mass index and waist circumference were discovered. Compared to the changes between the two groups, the results showed there were significant differences in waist circumference, systolic blood pressure, diastolic blood pressure and high-density lipoprotein cholesterol. The community-based intervention could help to improve high-density lipoprotein cholesterol, reduce body weight, body mass index, waist circumference, blood pressure and fasting blood glucose in metabolically abnormal obese. This community-based programme helped metabolically abnormal

The re-use of previously validated designs is critical to the evolution of synthetic biology from a research discipline to an engineering practice. Here we describe the Synthetic Biology Open Language (SBOL), a proposed data standard for exchanging designs within the synthetic biology community. SBOL represents synthetic biology designs in a community-driven, formalized format for exchange between software tools, research groups and commercial service providers. The SBOL Developers Group has implemented SBOL as an XML/RDF serialization and provides software libraries and specification documentation to help developers implement SBOL in their own software. We describe early successes, including a demonstration of the utility of SBOL for information exchange between several different software tools and repositories from both academic and industrial partners. As a community-driven standard, SBOL will be updated as synthetic biology evolves to provide specific capabilities for different aspects of the synthetic biology workflow.

There is little research into the patterns of mental health services use, related factors, and barriers in help-seeking behaviors among the community population in northwestern China. We conducted a community-based survey among the general population in Xi'an City with the stratified two-stage systematic selection scheme using the World Health Organization Composite International Diagnostic Interview version 3.0 computer-assisted personal interview (CIDI-CAPI 3.0). We interviewed 2447 individuals aged 16 years or older. The lifetime prevalence estimate of mental disorders was 21%. However, the lifetime use rate of mental health services of the 2447 responding subjects was 2.45% and 4.67% among those subjects who reported a mental disorder. Several variables were associated with lower use of mental health services: rural residence and divorced or unmarried. Among the group with mental disorders, 15/21 sought help from non-mental health specialty services such as a general physician (13/21). The high prevalence rate of mental disorders but low rate of mental health services use raises a significant public health issue in northwestern China. Reduction in the resource gap and encouraging people to seek treatment remain a challenge to the mental health services system. Copyright © 2018 Elsevier B.V. All rights reserved.

2012-10-01

Full Text Available Abstract Background According to the Pakistan Demographic and Health Survey from 2006–2007, the maternal mortality ratio in rural areas is 319 per 100,000 live births. Postpartum hemorrhage is the leading cause of maternal deaths in Pakistan. The objectives of the study were to document the feasibility of distribution of misoprostol tablets by community-based providers mainly traditional birth attendants and acceptability and use of misoprostol by women who gave birth at home. Methods A quasi-experimental design, comprising intervention and comparison areas, was used to document the acceptability of providing misoprostol tablets to pregnant women to prevent postpartum hemorrhage in the rural community setting in Pakistan. Data were collected using structured questionnaires administered to women before and after delivery at home and their birth attendants. Results Out of 770 women who delivered at home, 678 (88% ingested misoprostol tablets and 647 (84% ingested the tablets after the birth of the neonate but prior to the delivery of the placenta. The remaining women took misoprostol tablets after delivery of the placenta. Side effects were experienced by 40% of women and were transitory in nature. Among women who delivered at home, 80% said that they would use misoprostol tablets in the future and 74% were willing to purchase them in the future. Conclusions Self-administration of misoprostol in the home setting is feasible. Community-based providers, such as traditional birth attendants and community midwives with proper training and counseling, play an important role in reducing postpartum hemorrhage. Proper counseling and information exchange are helpful for introducing new practices in resource-constrained rural communities. Until such a time that skilled birth attendance is made more universally available in the rural setting, alternative strategies, such as training and using the services of traditional birth attendants to provide safe

In order to enhance the exhaust waste heat recovery efficiency of the automotive exhaust-based thermoelectric generator (TEG) system, a three-segment heat exchanger with folded-shaped internal structure for the TEG system is investigated in this study. As the major effect factors of the performance for the TEG system, surface temperature, and thermal uniformity of the heat exchanger are analyzed in this research, pressure drop along the heat exchanger is also considered. Based on computational fluid dynamics simulations and temperature distribution, the pressure drop along the heat exchanger is obtained. By considering variable length and thickness of folded plates in each segment of the heat exchanger, response surface methodology and optimization by a multi-objective genetic algorithm is applied for surface temperature, thermal uniformity, and pressure drop for the folded-shaped heat exchanger. An optimum design based on the optimization is proposed to improve the overall performance of the TEG system. The performance of the optimized heat exchanger in different engine conditions is discussed.

In three-party password authenticated key exchange (AKE) protocol, since two users use their passwords to establish a secure session key over an insecure communication channel with the help of the trusted server, such a protocol may suffer the password guessing attacks and the server has to maintain the password table. To eliminate the shortages of password-based AKE protocol, very recently, according to chaotic maps, Lee et al. [2015 Nonlinear Dyn. 79 2485] proposed a first three-party-authenticated key exchange scheme without using passwords, and claimed its security by providing a well-organized BAN logic test. Unfortunately, their protocol cannot resist impersonation attack, which is demonstrated in the present paper. To overcome their security weakness, by using chaotic maps, we propose a biometrics-based anonymous three-party AKE protocol with the same advantages. Further, we use the pi calculus-based formal verification tool ProVerif to show that our AKE protocol achieves authentication, security and anonymity, and an acceptable efficiency.

The reactivity of anion-exchange resins by applying OT-for-OH exchange reaction in the equilibrium state

International Nuclear Information System (INIS)

Kano, Naoki; Nihei, Makoto; Imaizumi, Hiroshi

1996-01-01

In order to reveal the behavior of hydroxyl group in isotope exchange reaction, OT-for-OH exchange reaction between each anion-exchange resin (OH - form) and tritiated water (abbreviated as HTO water below) was observed at 80degC under the equilibrium. Anion-exchange resins used were Amberlite IRA-400, IRA-410 (both strongly basic), and IRA-94S (weakly basic). It can be thought that an HTO molecule dissociates into H + +OT - (or T + +OH - ). The activity of each resin based on OT-for-OH exchange reaction was measured with a liquid scintillation counter. From the above-mentioned, the following five were found. Isotope exchange reaction as 'atomic group' occurred between the OH group in each anion-exchange resin and the OT group in HTO water. The reactivity of strongly basic anion-exchange resin is larger than that of weakly basic one. The ratio of the reactivity of these resins can roughly be expressed as follows: (IRA-410): (IRA-400): (IRA-94S)=42: 7: 1. The degree of OT-for-OH exchange reaction may be smaller than that of T-for-H exchange reaction. The method used and results obtained in this work may be helpful to obtain the data for the prevention of T-contamination, especially to obtain the data from certain atomic groups including T.

Community-based adaptation to climate change: an update

Energy Technology Data Exchange (ETDEWEB)

Ayers, Jessica; Huq, Saleemul

2009-06-15

Over a billion people - the world's poorest and most bulnerable communities – will bear the brunt of climate change. For them, building local capacity to cope is a vital step towards resilience. Community-based adaptation (CBA) is emerging as a key response to this challenge. Tailored to local cultures and conditions, CBA supports and builds on autonomous adaptations to climate variability, such as the traditional baira or floating gardens of Bangladesh, which help small farmers' crops survive climate-driven floods. Above all, CBA is participatory – a process involving both local stakeholders, and development and disaster risk reduction practitioners. As such, it builds on existing cultural norms while addressing local development issues that contribute to climate vulnerability. CBA is now gaining ground in many regions, and is ripe for the reassessment offered here.

Sharma, B.K.; Subramanian, R.; Mathur, P.K.

1994-01-01

The optimum conditions for the regeneration of strong base anion exchange resins of type-I and type-II were determined for cost-effective separation of isotopes of boron by ion exchange chromatography where the hydroxyl form of an anion exchange resin is equilibrated with boric acid solution containing mannitol as a complexing reagent. The possibility of using unspent alkali content of the effluent was also exploited. Removal of carbonate impurity from Rayon grade caustic lye (used as regenerant after dilution) and recycling of Ba(OH) 2 was studied to avoid waste disposal problems. (author)

Network-Based Community Brings forth Sustainable Society

Science.gov (United States)

Kikuchi, Toshiko

It has already been shown that an artificial society based on the three relations of social configuration (market, communal, and obligatory relations) functioning in balance with each other formed a sustainable society which the social reproduction is possible. In this artificial society model, communal relations exist in a network-based community with alternating members rather than a conventional community with cooperative mutual assistance practiced in some agricultural communities. In this paper, using the comparison between network-based communities with alternating members and conventional communities with fixed members, the significance of a network-based community is considered. In concrete terms, the difference in appearance rate for sustainable society, economic activity and asset inequality between network-based communities and conventional communities is analyzed. The appearance rate for a sustainable society of network-based community is higher than that of conventional community. Moreover, most of network-based communities had a larger total number of trade volume than conventional communities. But, the value of Gini coefficient in conventional community is smaller than that of network-based community. These results show that communal relations based on a network-based community is significant for the social reproduction and economic efficiency. However, in such an artificial society, the inequality is sacrificed.

A critical examination of community-based responses to household food insecurity in Canada.

Science.gov (United States)

Tarasuk, V

2001-08-01

Over the past two decades, household food insecurity has emerged as a significant social problem and serious public health concern in the "First World." In Canada, communities initially responded by establishing ad hoc charitable food assistance programs, but the programs have become institutionalized. In the quest for more appropriate and effective responses, a variety of community development programs have recently been initiated. Some are designed to foster personal empowerment through self-help and mutual support; others promote community-level strategies to strengthen local control over food production. The capacity of current initiatives to improve household food security appears limited by their inability to overcome or alter the poverty that under-pins this problem. This may relate to the continued focus on food-based responses, the ad hoc and community-based nature of the initiatives, and their origins in publicly funded health and social service sectors.

There is convincing empirical evidence that the cycle for exchange-rate-based disinflation in high-inflation Latin American economies typically begins with expansion and ends in recession - a surprising pattern. The authors explore whether a similar cycle can be observed in exchange-rate-based disinflation in low-inflation economies. They draw on empirical evidence from stabilizaton programs in three European countries in the early 1980s: in Denmark (1982), Ireland (1982), and France (1983). ...

Investments in community-based HIV prevention programs in Ontario over the past two and a half decades are assumed to have had an impact on the HIV epidemic, but they have never been systematically evaluated. To help close this knowledge gap, we conducted a macro-level evaluation of investment in Ontario HIV prevention programs from the payer perspective. Our results showed that, from 1987 to 2011, province-wide community-based programs helped to avert a total of 16,672 HIV infections, saving Ontario's health care system approximately $6.5 billion Canadian dollars (range 4.8-7.5B). We also showed that these community-based HIV programs were cost-saving: from 2005 to 2011, every dollar invested in these programs saved about $5. This study is an important first step in understanding the impact of investing in community-based HIV prevention programs in Ontario and recognizing the impact that these programs have had in reducing HIV infections and health care costs.

Economic and environmental impacts of community-based residential building energy efficiency investment

Choi, Jun-Ki; Morrison, Drew; Hallinan, Kevin P.; Brecha, Robert J.

2014-01-01

A systematic framework for evaluating the local economic and environmental impacts of investment in building energy efficiency is developed. Historical residential building energy data, community-wide economic input–output data, and emission intensity data are utilized. The aim of this study is to show the comprehensive insights and connection among achieving variable target reductions for a residential building energy use, economic and environmental impacts. Central to this approach for the building energy reduction goal is the creation of individual energy models for each building based upon historical energy data and available building data. From these models, savings estimates and cost implications can be estimated for various conservation measures. A ‘worst to first’ (WF) energy efficient investment strategy is adopted to optimize the level of various direct, indirect, and induced economic impacts on the local community. This evaluation helps to illumine opportunities to establish specific energy reduction targets having greatest economic impact in the community. From an environmental perspective, short term economy-wide CO 2 emissions increase because of the increased community-wide economic activities spurred by the production and installation of energy efficiency measures, however the resulting energy savings provide continuous CO 2 reduction for various target savings. - Highlights: • WF energy efficient strategy helps to optimize various level of economic impacts. • Greatest community benefits are achieved from specific energy reduction targets. • Community-wide economic impacts vary for different energy conservation measures

Attitudes Towards Seeking Psychological Help: An Integrative Model Based on Contact, Essentialist Beliefs About Mental Illness, and Stigma.

Science.gov (United States)

Hantzi, Alexandra; Anagnostopoulos, Fotios; Alexiou, Eva

2018-06-16

Based on intergroup contact theory, a proposed comprehensive model of attitudes towards seeking professional psychological help was tested, including both potential barriers to mental health help-seeking (i.e., public stigma and self-stigma of seeking help, prejudicial and essentialist beliefs about mental illness, intergroup anxiety) and potential facilitators (i.e., direct and extended contact with persons with mental illness). Relevant measures were completed by 119 community-dwelling participants. Path analysis showed that direct (but not extended) contact with mental illness, by reducing intergroup anxiety, led to less negative beliefs about mental illness and weaker essentialist beliefs about mental illness (the latter being directly and positively associated with negative beliefs about mental illness). Moreover, less negative beliefs about mental illness, by reducing perceptions of self (but not public) stigma of seeking psychological help, were related to more positive attitudes towards help-seeking. Results are discussed in the context of the (unintentional) adverse effects of biogenetic (essentialist) explanations of mental disorders, and the clinical implications regarding interventions that aim at improving help-seeking attitudes.

Social organization influences the exchange and species richness of medicinal plants in Amazonian homegardens.

Science.gov (United States)

2016-03-01

Medicinal plants provide indigenous and peasant communities worldwide with means to meet their healthcare needs. Homegardens often act as medicine cabinets, providing easily accessible medicinal plants for household needs. Social structure and social exchanges have been proposed as factors influencing the species diversity that people maintain in their homegardens. Here, we assess the association between the exchange of medicinal knowledge and plant material and medicinal plant richness in homegardens. Using Tsimane' Amazonian homegardens as a case study, we explore whether social organization shapes exchanges of medicinal plant knowledge and medicinal plant material. We also use network centrality measures to evaluate people's location and performance in medicinal plant knowledge and plant material exchange networks. Our results suggest that social organization, specifically kinship and gender relations, influences medicinal plant exchange patterns significantly. Homegardens total and medicinal plant species richness are related to gardeners' centrality in the networks, whereby people with greater centrality maintain greater plant richness. Thus, together with agroecological conditions, social relations among gardeners and the culturally specific social structure seem to be important determinants of plant richness in homegardens. Understanding which factors pattern general species diversity in tropical homegardens, and medicinal plant diversity in particular, can help policy makers, health providers, and local communities to understand better how to promote and preserve medicinal plants in situ. Biocultural approaches that are also gender sensitive offer a culturally appropriate means to reduce the global and local loss of both biological and cultural diversity.

Penkunas, Michael James; Eom, Kirsten Yuna; Chan, Angelique Wei-Ming

2017-10-01

Home- and center-based long-term care (LTC) services allow older adults to remain in the community while simultaneously helping caregivers cope with the stresses associated with providing care. Despite these benefits, the uptake of community-based LTC services among older adults remains low. We analyzed data from a longitudinal study in Singapore to identify the characteristics of individuals with referrals to home-based LTC services or day rehabilitation services at the time of hospital discharge. Classification and regression tree analysis was employed to identify combinations of clinical and sociodemographic characteristics of patients and their caregivers for individuals who did not take up their referred services. Patients' level of limitation in activities of daily living (ADL) and caregivers' ethnicity and educational level were the most distinguishing characteristics for identifying older adults who failed to take up their referred home-based services. For day rehabilitation services, patients' level of ADL limitation, home size, age, and possession of a national medical savings account, as well as caregivers' education level, and gender were significant factors influencing service uptake. Identifying subgroups of patients with high rates of non-use can help clinicians target individuals who are need of community-based LTC services but unlikely to engage in formal treatment.

2016-12-01

Small-population large-area states like Montana are often challenged by a need to offer timely and relevant climate-change information that addresses diverse and widely dispersed stakeholder groups. In Montana, filling the gap between science and various types of decision-makers has motivated development of the first Montana Climate Assessment (MCA1), to be released in 2017 with a focus on climate-change impacts for agricultural, water and forestry sectors. To sustain and build on the MCA1 effort, we are also in the process of creating a Boundary Organization (defined by the National Academy of Sciences) called the Montana Adaptation Exchange (the Exchange); this entity will facilitate the flow of information across the boundaries between science, knowledge and implementation. In Montana, the Exchange brings scientists and practitioners together to seek solutions related to climate-change adaptation and other pressing environmental and social-economic challenges. The Montana Adaptation Exchange (1) is a collaborative partnership of members from the science and practitioner communities under a shared governance and participatory model; (2) presents research that has been vetted by the scientific community at large and represents the current state of knowledge; (3) allows for revision and expansion of assessments like the MCA; (4) communicates relevant, often technical, research and findings to a wide variety of resource managers and other stakeholders; (5) develops and maintains an extensive online database that organizes, regularly updates, and makes research data products readily available; and (6) offers an online portal and expert network of affiliated researchers and climate adaptation specialists to provide effective customer support. Boundary organizations, such as the Montana Adaptation Exchange, offer a scalable path to effectively move from "science to knowledge to action" while also allowing stakeholder needs to help inform research agendas.

2012-08-01

Full Text Available Abstract Background As Home-and Community-Based Services (HCBS, such as skilled nursing services or personal care services, have become increasingly available, it has become clear that older adults transit through different residential statuses over time. Older adults may transit through different residential statuses as the various services meet their needs. The purpose of this exploratory study was to better understand the interplay between community-dwelling older adults’ use of home- and community-based services and their residential transitions. Methods The study compared HCBS service-use patterns and residential transitions of 3,085 older adults from the Second Longitudinal Study of Aging. Based on older adults’ residential status at the three follow-up interviews, four residential transitions were tracked: (1 Community-Community-Community (CCC: Resided in community during the entire study period; (2 Community-Institution-Community (CIC: Resided in community at T1, had lived in an institution at some time between T1 and T2, then had returned to community by T3; (3 Community-Community-Institution (CCI: Resided in community between at T1, and betweenT1 and T2, including at T2, but had used institutional services between T2 and T3; (4 Community-Institution-Institution (CII: Resided in community at T1 but in an institution at some time between T1 and T2, and at some time between T2 and T3.. Results Older adults’ use of nondiscretionary and discretionary services differed significantly among the four groups, and the patterns of HCBS use among these groups were also different. Older adults’ use of nondiscretionary services, such as skilled nursing care, may help them to return to communities from institutions. Personal care services (PCS and senior center services may be the key to either support elders to stay in communities longer or help elders to return to their communities from institutions. Different combinations of PCS with other

2017-08-01

Autism Spectrum Disorder (ASC) has widely gained the common attention from the public especially autistic communities. Individuals with ASC are said to have poor verbal skills and this affects them in carrying out their daily basis which they are afraid to expose themselves to the world due to their problems. ASC is diagnosed among children ranging from ages 5-12 years old and they suffer from the abnormal functioning of the brain which in turn causes lack of development activities. Thus, studies have shown that diagrammatic approaches help children with ASC to overcome their issues and improvise their visual and verbal skills. Picture Exchange Communication System or PECS consists of a series of illustrated cards and each cards has its own illustration with a caption on it. These children will understand the cards and they can compile several other cards to form sentences. This paper presents a mobile application called the Prospect, which has been developed using the agile development model for digital representation of PECS. The application is hoped to enhance the learning process and a better yielding results.

Closed Loop Brain Model of Neocortical Information Based Exchange

Directory of Open Access Journals (Sweden)

James eKozloski

2016-01-01

Full Text Available Here we describe an information based exchange' model of brain function that ascribes to neocortex, basal ganglia, and thalamus distinct network functions. The model allows us to analyze whole brain system set point measures, such as the rate and heterogeneity of transitions in striatum and neocortex, in the context of neuromodulation and other perturbations. Our closed-loop model is grounded in neuroanatomical observations, proposing a novel Grand Loop through neocortex, and invokes different forms of plasticity at specific tissue interfaces and their principle cell synapses to achieve these transitions. By implementing a system for maximum information based exchange of action potentials between modeled neocortical areas, we observe changes to these measures in simulation. We hypothesize that similar dynamic set points and modulations exist in the brain's resting state activity, and that different modifications to information based exchange may shift the risk profile of different component tissues, resulting in different neurodegenerative diseases. This model is targeted for further development using IBM's Neural Tissue Simulator, which allows scalable elaboration of networks, tissues, and their neural and synaptic components towards ever greater complexity and biological realism.

Tourism industry has become the highlighted sector which has amazingly increased the national income level. Despite the tourism industry being one of the highest income generating sectors, Homestay Programme as a Community-Based Tourism (CBT) product in Malaysia does not absorbed much of the incoming wealth. Homestay Programme refers to a programme in a community where a tourist stays together with a host family and experiences the everyday way of life of the family in both direct and indirect manner. There are over 100 Homestay Programme currently being registered with the Ministry of Culture and Tourism Malaysia which mostly are located in rural areas, but only a few excel and enjoying the fruit of the booming industry.

To explore the mediating effect of bother of urinary incontinence between urinary incontinence severity and help-seeking intentions and detect whether the International Consultation on Incontinence Questionnaire-UI Short Form could be a valid measure to delineate bothersome urinary incontinence. Urinary incontinence is a common condition among women, which has a profound adverse effect on quality of life. However, many of them experiencing significant clinical symptoms do not seek medical help. A cross-sectional survey design. Women with urinary incontinence (N = 620) from three randomized selected community health service centres from May-October 2011 participated in the study. Data were collected using a pencil-and-paper questionnaire. Multivariate regression models were used to test the role of bother as a mediator in the relation between urinary incontinence severity and help-seeking intentions. Receiver operating characteristic analysis was used to find the best cut-off International Consultation on Incontinence Questionnaire-UI Short Form score (range: 0-21) to delineate the bother of urinary incontinence. Bothersome urinary incontinence mediated the relationship between urinary incontinence severity and help-seeking intentions. Age and duration of urine leakage had a negative association on help-seeking intentions, while educational level and previous help-seeking behaviours had a positive association. Bother was a mediator in the relation between urinary incontinence severity and help-seeking intentions. The International Consultation on Incontinence Questionnaire-UI Short Form was a discriminative measure to delineate the bothersome urinary incontinence. © 2014 John Wiley & Sons Ltd.

Exchange coupling and magnetic anisotropy of exchanged-biased quantum tunnelling single-molecule magnet Ni3Mn2 complexes using theoretical methods based on Density Functional Theory.

Science.gov (United States)

Gómez-Coca, Silvia; Ruiz, Eliseo

2012-03-07

The magnetic properties of a new family of single-molecule magnet Ni(3)Mn(2) complexes were studied using theoretical methods based on Density Functional Theory (DFT). The first part of this study is devoted to analysing the exchange coupling constants, focusing on the intramolecular as well as the intermolecular interactions. The calculated intramolecular J values were in excellent agreement with the experimental data, which show that all the couplings are ferromagnetic, leading to an S = 7 ground state. The intermolecular interactions were investigated because the two complexes studied do not show tunnelling at zero magnetic field. Usually, this exchange-biased quantum tunnelling is attributed to the presence of intermolecular interactions calculated with the help of theoretical methods. The results indicate the presence of weak intermolecular antiferromagnetic couplings that cannot explain the ferromagnetic value found experimentally for one of the systems. In the second part, the goal is to analyse magnetic anisotropy through the calculation of the zero-field splitting parameters (D and E), using DFT methods including the spin-orbit effect.

Exergetic optimization of shell and tube heat exchangers using a genetic based algorithm

Energy Technology Data Exchange (ETDEWEB)

Oezcelik, Yavuz [Ege University, Bornova, Izmir (Turkey). Engineering Faculty, Chemical Engineering Department

2007-08-15

In the computer-based optimization, many thousands of alternative shell and tube heat exchangers may be examined by varying the high number of exchanger parameters such as tube length, tube outer diameter, pitch size, layout angle, baffle space ratio, number of tube side passes. In the present study, a genetic based algorithm was developed, programmed, and applied to estimate the optimum values of discrete and continuous variables of the MINLP (mixed integer nonlinear programming) test problems. The results of the test problems show that the genetic based algorithm programmed can estimate the acceptable values of continuous variables and optimum values of integer variables. Finally the genetic based algorithm was extended to make parametric studies and to find optimum configuration of heat exchangers by minimizing the sum of the annual capital cost and exergetic cost of the shell and tube heat exchangers. The results of the example problems show that the proposed algorithm is applicable to find optimum and near optimum alternatives of the shell and tube heat exchanger configurations. (author)

K-based Help desk system is a knowledge oriented web based system that provides support to technical service providers in order to improve delivery of their services. It is a multi-centric system which focuses not only on end-users but the various levels of technical support services as well as the management through the utilization of knowledge which resides and grows within the system. Though providing user friendly system and capturing technical knowledge to improve efficiencies are the main objectives of this system, educating users with technical information through the knowledge utilization system are the spin-off target from this implementation. This is achieved by preventing the service providers from handling repetitive complaints which may have similarity in nature. Once a complaint has been resolved, the system captures the solution as an item in the knowledge database. The captured knowledge will then enable service requesters or users to get some ideas regarding their complaints from information or knowledge of other similar complaints besides providing relevant knowledge to the service provider such as the techniques used in solving problems and the performance among the technical support staffs. As for the management, this system helps in the decision making process in which the statistics features provide some knowledge on the number of equipment that frequently and consistently failed. This then leads to some understanding of the equipment that may create lost to the organization in terms of time and money. This system has been tested and implemented in IT Center (IT) and Engineering Division (BKJ) and is at the initial process of implementation in the Instrumentation and Automation Center (IAC) at Malaysian Nuclear Agency (Nuclear Malaysia). The system has helped in achieving a higher level of user satisfaction and a faster growth in technical knowledge repository that will serve as the institutional memory of Nuclear Malaysia and this will be

The Role of Perceptions for Community-Based Marine Resource Management

Directory of Open Access Journals (Sweden)

Katharina Beyerl

2016-11-01

Full Text Available Every community-based marine resource management (CBMRM inherently takes place in a highly complex social-ecological environment, and stakeholder perceptions related to various aspects of the natural and social environment guide behavior in every stage of the management process. This paper provides an introduction to the psychology of perception with regard to marine resource management. In particular, it offers a typology of CBMRM relevant perceptions along with an analysis of psychological, societal, and physical factors that modulate them. Based on this analysis, we propose the introduction of specially trained local Perception Experts (PE’s, whose role will be to recognize and reflect individual perceptions of involved stakeholders, and to communicate them at community meetings where decisions are made. This empirically testable addition to current CBMRM schemes could help to increase participation, develop management measures that fit the capacities of the involved stakeholders more accurately, and hence, contribute to a faster rehabilitation of marine resources.

[Community-based health promotion--a challenge for the evaluation].

2007-02-01

Community-based health promotion (CBHP) aims at mobilising citizens for health-related issues in their environment, and at implementing health-promoting projects on the community level. Whereas recent political decisions support this approach, scientific studies dealing with theories and consequences of CBHP are scarce in Germany. Evaluation of CBHP could help identify (in)effective factors and elements of community programmes and thus improve future planning. In Germany, however, there is a deficit in systematic concepts and recommendations for the evaluation of CBHP. This work outlines basic ideas and core principles of CBHP and deduces implications for the assessment of health-promoting community projects. Based on different international models and studies and on discussions with health promotion professionals, we developed a framework for the evaluation of CBHP. The proposed framework includes a guideline for CBHP programme planning. Its strategic and operational criteria can serve as a basis for a strategy evaluation. In terms of process evaluation, indicators for the dimensions (1) programme implementation and service delivery, (2) capacity building, and (3) reach of and acceptability in the target group were developed. In addition, we present different areas of OUTCOME EVALUATION; it is advisable to distinguish between measurement on the individual and on the community level. The framework further proposes strategies for the evaluation of the core principles empowerment and participation. The presented framework can serve as a basis for the development of flexible and individual instruments for the evaluation of CBHP, which should not ignore the perspective of the citizens, or complex aspects like changes on the community level. Some aspects, e.g., the potential evaluation of further targets of CBHP (improvement of quality of life, reduction of social and health inequalities), the responsibility of evaluation or the effects of financial constraints, are

Self-help and help-seeking for communication disability in Ghana: implications for the development of communication disability rehabilitation services.

In low and middle-income countries, such as Ghana, communication disability is poorly recognised and rehabilitation services for people with communication disability are limited. As rehabilitation services for communication disability develop, and the profession of speech-language pathology grows, it is important to consider how services can most appropriately respond to the needs and preferences of the community. Understanding the ways in which people currently self-help and seek help for communication disability is central to developing services that build on existing local practices and are relevant to the community. A qualitative descriptive survey was used to explore likely self-help and help-seeking behaviours for communication disability, in Accra, Ghana. The survey required participants to describe responses to hypothetical scenarios related to communication disability. A mix of theoretical sampling and convenience sampling was used. Qualitative content analysis was used to analyse data and develop categories and subcategories of reported self-help behaviours and sources of help and advice for communication disability. One hundred and thirty-six participants completed the survey. Results indicated that community members would be likely to engage in a variety self-help strategies in response to communication disability. These included working directly with a person with a communication disability to attempt to remediate a communication impairment, altering physical and communication environments, changing attitudes or care practices, educating themselves about the communication disability, providing resources, and responding in spiritual ways. Participants indicated that they would seek help for communication disability across a range of sectors - including the Western healthcare, religious, and traditional sectors. Understanding existing community actions to self-help and help-seek may allow emerging communication rehabilitation services, including the

Barrier versus tilt exchange gate operations in spin-based quantum computing

Science.gov (United States)

Shim, Yun-Pil; Tahan, Charles

2018-04-01

We present a theory for understanding the exchange interaction between electron spins in neighboring quantum dots, either by changing the detuning of the two quantum dots or independently tuning the tunneling barrier between quantum dots. The Hubbard model and a more realistic confining-potential model are used to investigate how the tilting and barrier control affect the effective exchange coupling and thus the gate fidelity in both the detuning and symmetric regimes. We show that the exchange coupling is less sensitive to the charge noise through tunnel barrier control (while allowing for exchange coupling operations on a sweet spot where the exchange interaction has zero derivative with respect to the detuning). Both GaAs and Si quantum dots are considered, and we compare our results with experimental data showing qualitative agreements. Our results answer the open question of why barrier gates are preferable to tilt gates for exchange-based gate operations.

Sasai, T.; Murakami, K.; Kato, S.; Matsunaga, T.; Saigusa, N.; Hiraki, K.

2015-12-01

Global terrestrial carbon cycle largely depends on a spatial pattern in land cover type, which is heterogeneously-distributed over regional and global scales. However, most studies, which aimed at the estimation of carbon exchanges between ecosystem and atmosphere, remained within several tens of kilometers grid spatial resolution, and the results have not been enough to understand the detailed pattern of carbon exchanges based on ecological community. Improving the sophistication of spatial resolution is obviously necessary to enhance the accuracy of carbon exchanges. Moreover, the improvement may contribute to global warming awareness, policy makers and other social activities. In this study, we show global terrestrial carbon exchanges (net ecosystem production, net primary production, and gross primary production) with 1km-grid resolution. As methodology for computing the exchanges, we 1) developed a global 1km-grid climate and satellite dataset based on the approach in Setoyama and Sasai (2013); 2) used the satellite-driven biosphere model (Biosphere model integrating Eco-physiological And Mechanistic approaches using Satellite data: BEAMS) (Sasai et al., 2005, 2007, 2011); 3) simulated the carbon exchanges by using the new dataset and BEAMS by the use of a supercomputer that includes 1280 CPU and 320 GPGPU cores (GOSAT RCF of NIES). As a result, we could develop a global uniform system for realistically estimating terrestrial carbon exchange, and evaluate net ecosystem production in each community level; leading to obtain highly detailed understanding of terrestrial carbon exchanges.

The vigorous development of nuclear technology and atomic energy and the hydrometallurgy of the rare and radioactive metals has made it necessary to create and use ion-exchange materials possessing a high resistance to the action of ionizing radiations and the temperature. In view of this, the necessity has arisen for obtaining ion-exchange materials possessing adequate radiation stability. The results of an investigation of the radiation stability of anion-exchange resins based on the products of spontaneous polymerization in the interaction of epichlorohydrin with vinylpyridines show that they possess higher radiation resistance than the industrial anion-exchange resin AN-31 used at the present time

Professional ideologies and the development of syringe exchange: Wales as a case study.

Science.gov (United States)

Keene, J M; Stimson, G V

1997-12-01

This paper is derived from an evaluative study of HIV prevention programs for drug injectors across Wales. It considers how different professional territories and ideologies, concepts of drug misuse and models of HIV prevention may influence policy development. The research involved monitoring the introduction and development of agency and community based syringe exchange schemes and initiatives taken by community pharmacists. Interviews with staff, managers and administrators, and descriptions of service history, development and delivery inform the discussion. HIV prevention varied in different areas of Wales depending on the particular professional group involved, local ideologies regarding drug use treatment, and the extent to which HIV prevention was seen either as a specialist area of expertise and specific remit of drug workers or a generic health care task. Drug agencies with an abstinence policy rejected syringe exchange; instead, prevention in those areas developed in ad hoc ways as health care workers and pharmacists attempted to develop a community based service. Drug agencies with a pre-existing harm minimisation model easily integrated syringe exchange into their work and played the major part in establishing the service, but there was difficulty in extending it beyond their professional caseloads. As there were disincentives to use treatment agencies, and their catchment areas were limited, these factors influenced effective service provision.

Mechanistic study of the isotopic-exchange reaction between gaseous hydrogen and palladium hydride powder

Outka, D.A.; Foltz, G.W.

1991-01-01

A detailed mechanism for the isotopic-exchange reaction between gaseous hydrogen and solid palladium hydride is developed which extends previous model for this reaction by specifically including surface reactions. The modeling indicates that there are two surface-related processes that contribute to the overall rate of exchange: the desorption of hydrogen from the surface and the exchange between surface hydrogen and bulk hydrogen. This conclusion is based upon measurements examining the effect of small concentrations of carbon monoxide were helpful in elucidating the mechanism. Carbon monoxide reversibly inhibits certain steps in the exchange; this slows the overall rate of exchange and changes the distribution of products from the reactor

Microbial communities are each a composite of populations whose presence and relative abundance in water or other environmental samples are a direct manifestation of environmental conditions, including the introduction of microbe-rich fecal material and factors promoting persistence of the microbes therein. As shown by culture-independent methods, different animal-host fecal microbial communities appear distinctive, suggesting that their community profiles can be used to differentiate fecal samples and to potentially reveal the presence of host fecal material in environmental waters. Cross-comparisons of microbial communities from different hosts also reveal relative abundances of genetic groups that can be used to distinguish sources. In increasing order of their information richness, several community analysis methods hold promise for MST applications: phospholipid fatty acid (PLFA) analysis, denaturing gradient gel electrophoresis (DGGE), terminal restriction fragment length polymorphism (TRFLP), cloning/sequencing, and PhyloChip. Specific case studies involving TRFLP and PhyloChip approaches demonstrate the ability of community-based analyses of contaminated waters to confirm a diagnosis of water quality based on host-specific marker(s). The success of community-based MST for comprehensively confirming fecal sources relies extensively upon using appropriate multivariate statistical approaches. While community-based MST is still under evaluation and development as a primary diagnostic tool, results presented herein demonstrate its promise. Coupled with its inherently comprehensive ability to capture an unprecedented amount of microbiological data that is relevant to water quality, the tools for microbial community analysis are increasingly accessible, and community-based approaches have unparalleled potential for translation into rapid, perhaps real-time, monitoring platforms.

There is an emerging and urgent need for new approaches for the management of environmental challenges such as flood hazard in the broad context of sustainability. This requires a new way of working which bridges disciplines and organisations, and that breaks down science-culture boundaries. With this, there is growing recognition that the appropriate involvement of local communities in catchment management decisions can result in multiple benefits. However, new tools are required to connect organisations and communities. The growth of cloud based technologies offers a novel way to facilitate this process of exchange of information in environmental science and management; however, stakeholders need to be engaged with as part of the development process from the beginning rather than being presented with a final product at the end. Here we present the development of a pilot Local Environmental Virtual Observatory Flooding Tool. The aim was to develop a cloud based learning platform for stakeholders, bringing together fragmented data, models and visualisation tools that will enable these stakeholders to make scientifically informed environmental management decisions at the local scale. It has been developed by engaging with different stakeholder groups in three catchment case studies in the UK and a panel of national experts in relevant topic areas. However, these case study catchments are typical of many northern latitude catchments. The tool was designed to communicate flood risk in locally impacted communities whilst engaging with landowners/farmers about the risk of runoff from the farmed landscape. It has been developed iteratively to reflect the needs, interests and capabilities of a wide range of stakeholders. The pilot tool combines cloud based services, local catchment datasets, a hydrological model and bespoke visualisation tools to explore real time hydrometric data and the impact of flood risk caused by future land use changes. The novel aspects of the

Lam, P.S.; Sindelar, R.L.; Barnes, D.M.; Awadalla, N.G.

1992-01-01

The primary coolant piping system of the Savannah River Site (SRS) reactors contains twelve heat exchangers to remove the waste heat from the nuclear materials production. A large break at the inlet or outlet heads of the heat exchangers would occur if the restraint members of the heads become inactive. The heat exchanger head is attached to the tubesheet by 84 staybolts. The structural integrity of the heads is demonstrated by showing the redundant capacity of the staybolts to restrain the head at design conditions and under seismic loadings. The beat exchanger head is analyzed with a three- dimensional finite element model. The restraint provided by the staybolts is evaluated for several postulated cases of inactive or missing staybolts, that is, bolts that have a flaw exceeding the ultrasonic testing (UT) threshold depth of 25% of the bolt diameter. A limit of 6 inactive staybolts is reached with a fracture criterion based on the maximum allowable local displacement at the active staybolts which corresponds to the crack tip opening displacement (CTOD) of 0.032 inches. An acceptance criteria methodology has been developed to disposition flaws reported in the staybolt inspections while ensuring adequate restraint capacity of the staybolts to maintain integrity of the heat exchanger heads against collapse. The methodology includes an approach for the baseline and periodic inspections of the staybolts. A total of up to 6 staybolts, reported as containing flaws with depths at or exceeding 25% would be acceptable in the heat exchanger

Cyclone Nargis hit Burma on May 2, 2008, killing over 138,000 and affecting at least 2.4 million people. The Burmese military junta, the State Peace and Development Council (SPDC), initially blocked international aid to storm victims, forcing community-based organizations such as the Emergency Assistance Teams-Burma (EAT) to fill the void, helping with cyclone relief and long-term reconstruction. Recognizing the need for independent monitoring of the human rights situation in cyclone-affected areas, particularly given censorship over storm relief coverage, EAT initiated such documentation efforts. A human rights investigation was conducted to document selected human rights abuses that had initially been reported to volunteers providing relief services in cyclone affected areas. Using participatory research methods and qualitative, semi-structured interviews, EAT volunteers collected 103 testimonies from August 2008 to June 2009; 42 from relief workers and 61 from storm survivors. One year after the storm, basic necessities such as food, potable water, and shelter remained insufficient for many, a situation exacerbated by lack of support to help rebuild livelihoods and worsening household debt. This precluded many survivors from being able to access healthcare services, which were inadequate even before Cyclone Nargis. Aid efforts continued to be met with government restrictions and harassment, and relief workers continued to face threats and fear of arrest. Abuses, including land confiscation and misappropriation of aid, were reported during reconstruction, and tight government control over communication and information exchange continued. Basic needs of many cyclone survivors in the Irrawaddy Delta remained unmet over a year following Cyclone Nargis. Official impediments to delivery of aid to storm survivors continued, including human rights abrogations experienced by civilians during reconstruction efforts. Such issues remain unaddressed in official assessments

The use of crystal methamphetamine (ice) and the associated harms for individuals, families, and communities across Australia has been the subject of growing concern in recent years. The provision of easily accessible, evidence-based, and up-to-date information and resources about crystal methamphetamine for the community is a critical component of an effective public health response. This paper aims to describe the codevelopment process of the Web-based Cracks in the Ice Community Toolkit, which was developed to improve access to evidence-based information and resources about crystal methamphetamine for the Australian community. Development of the Cracks in the Ice Community Toolkit was conducted in collaboration with community members across Australia and with experts working in the addiction field. The iterative process involved the following: (1) consultation with end users, including community members, crystal methamphetamine users, families and friends of someone using crystal methamphetamine, health professionals, and teachers (n=451) via a cross-sectional Web-based survey to understand information needs; (2) content and Web development; and (3) user testing of a beta version of the Web-based toolkit among end users (n=41) and experts (n=10) to evaluate the toolkit's acceptability, relevance, and appeal. Initial end user consultation indicated that the most commonly endorsed reasons for visiting a website about crystal methamphetamine were "to get information for myself" (185/451, 41.0%) and "to find out how to help a friend or a family member" (136/451, 30.2%). Community consultation also revealed the need for simple information about crystal methamphetamine, including what it is, its effects, and when and where to seek help or support. Feedback on a beta version of the toolkit was positive in terms of content, readability, layout, look, and feel. Commonly identified areas for improvement related to increasing the level of engagement and personal connection

Public participation in the development of flood risk management and river basin management plans are explicit components of both the Water Framework and Floods Directives. At the local level, involving communities in land and water management has been found to (i) aid better environmental decision making, (ii) enhance social, economic and environmental benefits, and (iii) increase a sense of ownership. Facilitating the access and exchange of information on the local environment is an important part of this new approach to the land and water management process, which also includes local community stakeholders in decisions about the design and content of the information provided. As part of the Natural Environment Research Council's pilot Environment Virtual Observatory (EVO), the Local Level group are engaging with local community stakeholders in three different catchments in the UK (the rivers Eden, Tarland and Dyfi) to start the process of developing prototype visualisation tools to address the specific land and water management issues identified in each area. Through this local collaboration, we will provide novel visualisation tools through which to communicate complex catchment science outcomes and bring together different sources of environmental data in ways that better meet end-user needs as well as facilitate a far broader participatory approach in environmental decision making. The Local Landscape Visualisation Tools are being evolved iteratively during the project to reflect the needs, interests and capabilities of a wide range of stakeholders. The tools will use the latest concepts and technologies to communicate with and provide opportunities for the provision and exchange of information between the public, government agencies and scientists. This local toolkit will reside within a wider EVO platform that will include national datasets, models and state of the art cloud computer systems. As such, local stakeholder groups are assisting the EVO

Building a community-based culture of evaluation.

In this article we argue for a community-based approach as a means of promoting a culture of evaluation. We do this by linking two bodies of knowledge - the 70-year theoretical tradition of community-based research and the trans-discipline of program evaluation - that are seldom intersected within the evaluation capacity building literature. We use the three hallmarks of a community-based research approach (community-determined; equitable participation; action and change) as a conceptual lens to reflect on a case example of an evaluation capacity building program led by the Ontario Brian Institute. This program involved two community-based groups (Epilepsy Southwestern Ontarioand the South West Alzheimer Society Alliance) who were supported by evaluators from the Centre for Community Based Research to conduct their own internal evaluation. The article provides an overview of a community-based research approach and its link to evaluation. It then describes the featured evaluation capacity building initiative, including reflections by the participating organizations themselves. We end by discussing lessons learned and their implications for future evaluation capacity building. Our main argument is that organizations that strive towards a community-based approach to evaluation are well placed to build and sustain a culture of evaluation. Copyright © 2017 Elsevier Ltd.

Full Text Available This paper proposes that role stressors decrease helping behavior by undermining employees’ normative commitment from a cognitive dissonance perspective and social exchange theory. We also propose two competitive assumptions of the moderating effect of perceived organizational support (POS. In this paper, we first examine these hypotheses in Study 1 and then verify the cognitive dissonance perspective in Study 2. In Study 1, we collected data from 350 employees of two enterprises in China. The results indicated that role stressors had a negative link with helping behavior via the mediating role of normative commitment. The results also showed that POS strengthened the negative relationship between role stressors and normative commitment. In Study 2, we invited 104 employees to participate in a scenario experiment. The results found that role stressors had an impact on normative commitment via dissonance. Our studies verified the combination of cognitive dissonance perspective and social exchange theory to explain the impact of role stressors on helping behavior.

Value at risk estimation with entropy-based wavelet analysis in exchange markets

Science.gov (United States)

He, Kaijian; Wang, Lijun; Zou, Yingchao; Lai, Kin Keung

2014-08-01

In recent years, exchange markets are increasingly integrated together. Fluctuations and risks across different exchange markets exhibit co-moving and complex dynamics. In this paper we propose the entropy-based multivariate wavelet based approaches to analyze the multiscale characteristic in the multidimensional domain and improve further the Value at Risk estimation reliability. Wavelet analysis has been introduced to construct the entropy-based Multiscale Portfolio Value at Risk estimation algorithm to account for the multiscale dynamic correlation. The entropy measure has been proposed as the more effective measure with the error minimization principle to select the best basis when determining the wavelet families and the decomposition level to use. The empirical studies conducted in this paper have provided positive evidence as to the superior performance of the proposed approach, using the closely related Chinese Renminbi and European Euro exchange market.

QuakeML: Recent Development and First Applications of the Community-Created Seismological Data Exchange Standard

Science.gov (United States)

Euchner, F.; Schorlemmer, D.; Kästli, P.; Quakeml Group, T

2008-12-01

QuakeML is an XML-based exchange format for seismological data which is being developed using a community-driven approach. It covers basic event description, including picks, arrivals, amplitudes, magnitudes, origins, focal mechanisms, and moment tensors. Contributions have been made from ETH, GFZ, USC, SCEC, USGS, IRIS DMC, EMSC, ORFEUS, GNS, ZAMG, BRGM, and ISTI. The current release (Version 1.1, Proposed Recommendation) reflects the results of a public Request for Comments process which has been documented online at http://quakeml.org/RFC_BED_1.0. QuakeML has recently been adopted as a distribution format for earthquake catalogs by GNS Science, New Zealand, and the European-Mediterranean Seismological Centre (EMSC). These institutions provide prototype QuakeML web services. Furthermore, integration of the QuakeML data model in the CSEP (Collaboratory for the Study of Earthquake Predictability, http://www.cseptesting.org) testing center software developed by SCEC is under way. QuakePy is a Python- based seismicity analysis toolkit which is based on the QuakeML data model. Recently, QuakePy has been used to implement the PMC method for calculating network recording completeness (Schorlemmer and Woessner 2008, in press). Completeness results for seismic networks in Southern California and Japan can be retrieved through the CompletenessWeb (http://completenessweb.org). Future QuakeML development will include an extension for macroseismic information. Furthermore, development on seismic inventory information, resource identifiers, and resource metadata is under way.

Proton exchange in acid–base complexes induced by reaction coordinates with heavy atom motions

Alavi, Saman; Taghikhani, Mahdi

2012-01-01

Highlights: ► Proton exchange in acid–base complexes is studied. ► The structures, binding energies, and normal mode vibrations are calculated. ► Transition state structures of proton exchange mechanism are determined. ► In the complexes studied, the reaction coordinate involves heavy atom rocking. ► The reaction coordinate is not simply localized in the proton movements. - Abstract: We extend previous work on nitric acid–ammonia and nitric acid–alkylamine complexes to illustrate that proton exchange reaction coordinates involve the rocking motion of the base moiety in many double hydrogen-bonded gas phase strong acid–strong base complexes. The complexes studied involve the biologically and atmospherically relevant glycine, formic, acetic, propionic, and sulfuric acids with ammonia/alkylamine bases. In these complexes, the magnitude of the imaginary frequencies associated with the proton exchange transition states are −1 . This contrasts with widely studied proton exchange reactions between symmetric carboxylic acid dimers or asymmetric DNA base pair and their analogs where the reaction coordinate is localized in proton motions and the magnitude of the imaginary frequencies for the transition states are >1100 cm −1 . Calculations on complexes of these acids with water are performed for comparison. Variations of normal vibration modes along the reaction coordinate in the complexes are described.

2017-01-01

Prince Albert, Saskatchewan, is experiencing a substance use and addiction crisis with devastating consequences. To engage local stakeholders on substance use and addiction issues, nurse researchers at the University of Saskatchewan, Prince Albert Campus, planned and organized a one-day community engagement and knowledge exchange forum. The forum provided the opportunity for interested community groups, members and individuals to share their experiences and to explore novel ways to prevent and respond to the substance abuse and addiction challenges in the region. Participants included community leaders, people and families living with addiction, service providers, local stakeholders, health professionals, researchers and Indigenous Elders. This paper describes the process and outcomes of this event and describes the role of nurse scholars in leading these efforts. © 2017 Longwoods Publishing.

Embracing a competency-based specialty curriculum for community-based nursing roles.

Levin, Pamela F; Swider, Susan M; Breakwell, Susan; Cowell, Julia M; Reising, Virginia

2013-01-01

The Quad Council competencies for public health nursing (PHN) provide guidance in developing curricula at both the generalist and specialist level. However, these competencies are based on nursing roles in traditional public health agencies and community/public health is defined more broadly than official agency practice. The question arises as to whether community-based specialties require largely the same knowledge and skill set as PHN. The purpose of the competency cross-mapping project reported here was to (a) assess the intersection of the Quad Council competencies with four community-based specialties and (b) ensure the appropriateness of a Quad Council-based curriculum to prepare graduates across these four specialties (home health, occupational health, environmental health, and school nursing). This article details the multistep cross-mapping process, including validation with practice leaders. Results indicate strong alignment of community-based specialty competencies with Quad Council competencies. Community-based specialty-specific content that did not align well is identified, along with examples of didactic and clinical strategies to address gaps. This work indicates that a Quad Council-based curriculum is appropriate to prepare graduates in community-based specialties when attention to the specialty-specific competencies in the clinical setting is included. This work guides the development of a doctorate of nursing practice curriculum in PHN, encompassing the four additional community-based specialties. © 2013 Wiley Periodicals, Inc.

These studies were to respond whether the UT social-aid management had been executed under CO-CD principles (Ife J. 1995) and what CO-CD base community service management model can be built. The goals of these evaluational studies were UT social-aid managerial performance profile (2011-2013) and CO-CD management model development. The methods used were Survey and FGD. For data collection were involving the UT officers, the counterparts, and the documents. The analysis used combination between the Performance Analysis (Irawan P., 2003) and the CIPP (Stuffelbeam, D, L., & Shinkfield, A, J., 1985). The findings showed that the quantitative targeting in program completion was credible in achievement (85%). However, the “qulitative targeting” of the management goals was indicating far from a good-stage (≤5.0_Interval-Force: 1-10 Scale). The “Gap” was due to the absent of socialization_needs-analysis_maintenance_release factors on the UT social-service grand-policy. The trial of CO-CD Base Management Model had been imposed to the community that turned out to be very effective to self-help, and the ensuing SOP had been successfully defined. Conclusion, ‘CO-CD Principles’ were not designed in UT community service programs management. However, if efficiency and effectivity likely to be achieved, the SOP of ‘CO-CD Base Management Model has to be adopted.

Photography and Social Media Use in Community-Based Participatory Research with Youth: Ethical Considerations.

Science.gov (United States)

Kia-Keating, Maryam; Santacrose, Diana; Liu, Sabrina

2017-12-01

Community-based participatory researchers increasingly incorporate photography and social media into their work. Despite its relative infancy, social media has created a powerful network that allows individuals to convey messages quickly to a widespread audience. In addition to its potential benefits, the use of social media in research also carries risk, given the fast pace of exchanges, sharing of personal images and ideas in high accessibility, low privacy contexts and continually shifting options and upgrades. This article contributes to the literature examining ethical considerations for photography and social media use in community-based participatory research. We describe three key ethical dilemmas that we encountered during our participatory photography project with Latina/o youth: (a) use and content of images and risk; (b) incentives and coercion; and (c) social media activity and confidentiality. We provide our responses to these challenges, contextualized in theory and practice, and share lessons learned. We raise the question of how to contend with cultural shifts in boundaries and privacy. We propose that evaluating participant vulnerability versus potential empowerment may be more fitting than the standard approach of assessing risks and benefits. Finally, we recommend upholding the principles of participatory research by co-producing ethical practices with one's participants. © Society for Community Research and Action 2017.

The Use of the Clinical Ethnographic Narrative Interview to Understand and Support Help Seeking After Gender-Based Violence.

Saint Arnault, Denise M

2017-09-01

Gender-based violence (GBV), characterized by the abduction or rape of women and girls to humiliate, intimidate, and traumatize them and their communities, is a profoundly disturbing tactic in international conflict. Long after armed conflict has ended, survivors continue to experience physical injuries, psychological trauma, and social and cultural stigma. Guilt, shame, and continued interpersonal violence can become a normalized part of daily life, significantly challenging the road to healing and recovery. Research about self-disclosure and narrative after GBV has shown that help seeking rates are shockingly low, with estimates ranging from 4-27%. From a feminist and a humanistic perspective, studying trauma history and related help seeking is delicate work that must use interview processes that ensure the survivor can tell her story without revictimization, while also aiming to restore personal mastery, empowerment, and self-understanding. Based on theories about benefits and challenges of the narrative after GBV and trauma, we propose that the Clinical Ethnographic Narrative Interview (CENI) allows researchers and practitioners a safe container to examine the complex interplay between suffering, culture, and help seeking. Using this interview, the interviewer and the participant work as partners to define, compare, and contrast the socio-cultural barriers and facilitators of help seeking. This paper explains the narrative theory and the challenges and benefits of the narrative approach after trauma. Then we provide support for the use of the CENI for an understanding of the help seeking process and facilitating a health-promoting narrative interview for survivors. We then address implications for research, practice, and policy.

Estimates of psychiatric morbidity in the community will help service development. Participation of trained nonspecialist health-care providers will facilitate scaling up of services in resource-limited settings. This study aimed to estimate the prevalence of priority mental health problems in populations served by the District Mental Health Program (DMHP). This is a population-based cross-sectional survey. We did stratified cluster sampling of households in five districts of Kerala. Trained Accredited Social Health Activists (ASHAs) identified people who had symptoms suggestive of schizophrenia or bipolar disorder. Clinicians evaluated the information collected by the ASHAs and designated individuals as probable cases of psychosis or noncases. Screening instruments such as General Health Questionnaire-12, CAGE questionnaire, and Everyday Abilities Scale for India were used for identifying common mental disorders (CMDs), clinically significant alcohol-related problems, and functional impairment. We found 12.43% of the adult population affected by mental health conditions. We found CMD as most common with a prevalence of 9%. The prevalence of psychosis was 0.71%, clinically significant alcohol-related problems was 1.46%, and dementia and other cognitive impairments was 1.26%. We found informant-based case finding to be useful in the identification of psychosis. Mental health problems are common. Nonspecialist health-care providers can be trained to identify psychiatric morbidity in the community. Their participation will help in narrowing the treatment gap. Embedding operational research to DMHP will make scaling up more efficient.

Full Text Available Objective. A qualitative research methods approach was used to explore the experiences of participants in an ongoing community-based yoga program developed for cancer survivors and their support persons. Methods. 25 participants took part in a series of semistructured focus groups following a seven-week yoga program and at three- and six-month follow-ups. Focus groups were transcribed verbatim and analyzed using a process of inductive thematic analysis. Results. The group was comprised of 20 cancer survivors, who were diagnosed on average 25.40 (20.85 months earlier, and five support persons. Participants had completed the yoga program an average of 3.35 (3.66 times previously and attended approximately 1.64 (0.70 of three possible focus groups. Four key themes were identified: (1 safety and shared understanding; (2 cancer-specific yoga instruction; (3 benefits of yoga participation; (4 mechanisms of yoga practice. Conclusions. Qualitative research provides unique and in-depth insight into the yoga experience. Specifically, cancer survivors and support persons participating in a community-based yoga program discussed their experiences of change over time and were acutely aware of the beneficial effects of yoga on their physical, psychological, and social well-being. Further, participants were able to articulate the mechanisms they perceived as underpinning the relationship between yoga and improved well-being as they developed their yoga practice.

International exchange of radiological information in the event of a nuclear accident - future perspectives

Immediately after the Chernobyl accident most European countries established or enhanced their national radioactivity monitoring and information systems. The large transboundary effect of the radioactive release also triggered the need for bilateral and international agreements on the exchange of radiological information in case of a nuclear accident. Based on the experiences gained from existing bi- and multilateral data exchange the Commission of the European Communities has made provision for and is developing technical systems to exchange information of common interest. Firstly the existing national systems and systems based on bilateral agreements are summarized. The objectives and technical realizations of the EC international information exchange systems ECURIE and EURDEP, are described. The experiences gained over the past few years and the concepts for the future, in which central and eastern European countries will be included, are discussed. The benefits that would result from improving the international exchange of radiological information in the event of a future nuclear accident are further being described

Introducing False EUR and False EUR exchange rates

Science.gov (United States)

Ausloos, M.; Ivanova, K.

2000-10-01

The Euro ( EUR) is a new currency introduced by the European Community. Its exchange rate is very puzzling. We have invented a false Euro ( FEUR) dating back to 1993 and have derived the exchange rates of the FEUR with respect to currencies not belonging to the EUR, i.e., DKK, CHF, JPY and USD. This allows us to search for correlations between the fluctuations preexisting to the introduction of EUR and present ones in such financial data. The detrended fluctuation analysis ( DFA) statistical method is used. This leads to assume a power-law behavior, i.e., a scaling hypothesis, through an exponent α. The latter has demonstrated its usefulness for the investigations of long-range power-law correlations in several types of financial sequences. Our findings show that the α exponent interestingly characterizes fractional Brownian motion of the currency exchange rates between EUR and DKK over a 25 day interval, and usual Brownian motion otherwise and for the three other investigated exchange rates. We can devise an investment strategy based on the localα technique and obtain appreciable gains for the time being.

Exploring the co-production of digital storytelling for lay knowledge exchange within and between flood risk communities: the case of the River Severn, UK

Holmes Andrew

2016-01-01

Full Text Available This paper evaluates the potential role of co-produced digital storytelling as a medium of linking flood memories and lay knowledge exchange around flood preparedness for resilience within flood risk communities. The objectives of the described action focus on both process andd output - to capture memory of flood events, and to share critical reflection on, and adaptive learning from, flood experiences within and between communities. Very specific pieces of resilience stories on preparedness were co-produced into digital stories (audio and images working with individuals and small clusters of people. In the development process, stories were shared within the communities who created them, and within new communities. At all community events, the experience of sharing the stories was observed and evaluated using participant and facilitator questionnaires and independent observation. When shared in community events, the value of the digital media, nature of the story construction, the local or transferable nature of messages, and emotional weight given to the story were all appraised. The stories stimulated new discussions within different community groups and in multi-stakeholder meetings; conversations generated by the same digital story were found to differ depending on the setting. Listeners had high degrees of empathy with the stories gaining insights around “mobilising community#x201D; and “developing emotional resilience”. The paper explores issues of engagement in order to produce a participatory media -demonstrating the process and tensions of exchanging knowledge, and how the cultural practice of digital storytelling can jump the divide to policymaking and function as a successful way of engaging a wider public at flood risk.

2014-06-03

Many smokers give up smoking on their own, but materials giving advice and information may help them and increase the number who quit successfully. The aims of this review were to determine: the effectiveness of different forms of print-based self-help materials, compared with no treatment and with other minimal contact strategies; the effectiveness of adjuncts to print-based self help, such as computer-generated feedback, telephone hotlines and pharmacotherapy; and the effectiveness of approaches tailored to the individual compared with non-tailored materials. We searched the Cochrane Tobacco Addiction Group trials register. Date of the most recent search April 2014. We included randomized trials of smoking cessation with follow-up of at least six months, where at least one arm tested a print-based self-help intervention. We defined self help as structured programming for smokers trying to quit without intensive contact with a therapist. We extracted data in duplicate on the participants, the nature of the self-help materials, the amount of face-to-face contact given to intervention and to control conditions, outcome measures, method of randomization, and completeness of follow-up.The main outcome measure was abstinence from smoking after at least six months follow-up in people smoking at baseline. We used the most rigorous definition of abstinence in each trial, and biochemically validated rates when available. Where appropriate, we performed meta-analysis using a fixed-effect model. We identified 74 trials which met the inclusion criteria. Many study reports did not include sufficient detail to judge risk of bias for some domains. Twenty-eight studies (38%) were judged at high risk of bias for one or more domains but the overall risk of bias across all included studies was judged to be moderate, and unlikely to alter the conclusions.Thirty-four trials evaluated the effect of standard, non-tailored self-help materials. Pooling 11 of these trials in which there

Persistent stigma, lack of knowledge about mental health, and negative attitudes toward treatment are among the most significant barriers to military service members and veterans seeking behavioral health care. With the high rates of untreated behavioral health needs among service members and veterans, identifying effective programs for reducing barriers to care is a national priority. This study adapted Mental Health First Aid (MHFA), an evidence-based program for increasing mental health knowledge, decreasing stigma, and increasing laypeople's confidence in helping and frequency of referring people in need, for military and veteran populations and pilot tested the adapted training program with 4 Army National Guard armories. A total of 176 community first responders (CFRs) participated in a comparative outcomes study, with 69 receiving the training and 107 participating in the control group. CFRs were individuals in natural positions within the Armory or home communities of Guard members to identify and help service members in mental health crisis.

Bellows, Nicole M; Askew, Ian; Bellows, Benjamin

2015-01-01

Background One strategy for improving family planning (FP) uptake at the community level is the use of performance-based incentives (PBIs), which offer community distributors financial incentives to recruit more users of FP. This article examines the use of PBIs in community-based FP programmes via a literature search of the peer-reviewed and grey literature conducted in April 2013. Results A total of 28 community-based FP programmes in 21 countries were identified as having used PBIs. The most common approach was a sales commission model where distributors received commission for FP products sold, while a referral payment model for long-term methods was also used extensively. Six evaluations were identified that specifically examined the impact of the PBI in community-based FP programmes. Overall, the results of the evaluations are mixed and more research is needed; however, the findings suggest that easy-to-understand PBIs can be successful in increasing the use of FP at the community level. Conclusion For future use of PBIs in community-based FP programmes it is important to consider the ethics of incentivising FP and ensuring that PBIs are non-coercive and choice-enhancing.

Same sex attracted women (SSAW) are disproportionately affected by depression and anxiety, due to experiences of sexuality and gender based discrimination. They access mental health services at higher rates than heterosexual women, however with lower levels of satisfaction. This study examined the range of professional and social help seeking by same-sex attracted women, and patterns according to sexual orientation and gender identity subgroup. Eight key stakeholders were interviewed, and a convenience sample of 1628 Australian SSAW completed an online survey in 2015. This included several scales to measure mental health, community connectedness and resilience; and measured past 12 month help seeking behaviour, enablers, barriers and preferences for mental health care. Chi-square analyses and binary logistic regression analyses examined demographic associations with mental health. Correlations between help seeking, mental and physical health, and connectedness were run. A high proportion (80 %) of the total sample had perceived mental health problems over the past 12 months. Over half had depression, and over 96 % had anxiety. Trans and gender diverse participants were twice as likely as female participants to have mental health problems, and lesbians were least likely. High levels of past 12 month help seeking included 74.4 % seeing a GP, 44.3 % seeing a psychologist/counsellor, 74.7 % seeking family/friends support and 55.2 % using internet based support. Professional help was prioritised by those with higher mental health need. Trans participants were most likely to have sought professional help and participated in support groups, but least likely to have sought help from friends or family. The most common barriers to help seeking were discrimination and lack of LGBTI sensitivity of services, particularly for gender diverse, queer and pansexual participants. Enablers included mainstream community connectedness, having a trustworthy GP, and

Helping a community control its future: Potential negotiating packages and benefits for an MRS host

1993-01-01

The voluntary sitting process for the Monitored Retrievable Storage (MRS) facility set forth in the Nuclear Waste Policy Amendments Act (NWPAA) of 1987 provides a potential host community a unique opportunity to improve its present situation and to gain greater control over its future. To take full advantage of that opportunity throughout the life of the facility, an interested host must bring two things to the negotiating table: (1) a clear understanding of the special benefits, concerns and impacts associated with siting a controversial facility along with a detailed plan for addressing the requirements and impacts of such a facility; and (2) a vision of what the community wants to be in the future and list of specific measures it might achieve through negotiations that would help it realize that future. This paper investigates potential negotiating options a host might develop that, while addressing the impacts arena, also set forth terms by which the host can use the MRS to gain greater control over its unique set of resources and needs. The first section of this paper highlights the major concerns that a community might raise when debating whether to host an MRS and lists generic mitigation techniques that address those concerns. The second section pulls those mitigation techniques together into negotiating packages to show how the same concerns can be addressed differently depending on the strengths, weaknesses, and priorities of two different hypothetical host communities

We examined possible adverse effects of heavy metals on microbial activity, biomass, and community composition using the simultaneously extracted metals (SEM)/acid-volatile sulfide (AVS)-based approach and measurements of exchangeable metal concentrations in three paddy soils (wastewater-contaminated soil, mine-contaminated soil, and noncontaminated soil) incubated for 60 days under flooded conditions. Incubation under flooding increased pH and decreased Eh in all samples. AVS increased when Eh decreased to approximately -200 mV for the mine-contaminated and noncontaminated soils, while the wastewater-contaminated soil originally had a high concentration of AVS despite its air-dried condition. Addition of rice straw or alkaline material containing calcium carbonate and gypsum increased AVS levels under flooded conditions. We observed no apparent relationship between soil enzyme activity (β-D-glucosidase and acid phosphatase) and concentrations of SEM, [∑SEM - AVS], and exchangeable metals. Bacterial and fungal community composition, assessed using polymerase chain reaction-denaturing gradient gel electrophoresis (DGGE) analysis targeting rRNA genes, was largely influenced by site of collection and incubation time, but metal contamination did not influence community composition. We observed significant negative correlations between biomass C and [∑SEM - AVS] and between biomass C and ∑SEM, suggesting that [∑SEM - AVS] and ∑SEM might reflect the bioavailability of organic matter to microorganisms in these soils.

Research protocol: a realist synthesis of contestability in community-based mental health markets.

Science.gov (United States)

Durham, Jo; Bains, Amara

2015-03-25

In most developed nations, there has been a shift from public services to a marketisation of public goods and services - representing a significant reform process aiming to transform the way in which community-based human services, such as health, are delivered and consumed. For services, this means developing the capacity to adapt and innovate in response to changing circumstances to achieve quality. The availability of rigorous research to demonstrate whether a market approach and contestability, in particular, is a coherent reform process is largely absent. Contestability operates on the premise that better procurement processes allow more providers to enter the market and compete for contracts. This is expected to create stimulus for greater efficiencies, innovation and improved service delivery to consumers. There is limited understanding, however, about how community-based providers morph and re-configure in response to the opportunities posed by contestability. This study focuses on the effect of a contestability policy on the community-managed mental health sector. A realist review will be undertaken to understand how and why the introduction of contestability into a previously incontestable market influences the ways in which community-based mental health providers respond to contestability. The review will investigate those circumstances that shape organisational response and generate outcomes through activating mechanisms. An early scoping has helped to formulate the initial program theory. A realist synthesis will be undertaken to identify relevant journal articles and grey literature. Data will be extracted in relation to the emerging contextual factors, mechanisms and outcomes and their configurations. The analysis will seek patterns and regularities in these configurations across the extracted data and will focus on addressing our theory-based questions. Increasingly, community-based mental health markets are moving to contestability models. Rigorous

Exact-exchange-based quasiparticle calculations

Aulbur, Wilfried G.; Staedele, Martin; Goerling, Andreas

2000-01-01

One-particle wave functions and energies from Kohn-Sham calculations with the exact local Kohn-Sham exchange and the local density approximation (LDA) correlation potential [EXX(c)] are used as input for quasiparticle calculations in the GW approximation (GWA) for eight semiconductors. Quasiparticle corrections to EXX(c) band gaps are small when EXX(c) band gaps are close to experiment. In the case of diamond, quasiparticle calculations are essential to remedy a 0.7 eV underestimate of the experimental band gap within EXX(c). The accuracy of EXX(c)-based GWA calculations for the determination of band gaps is as good as the accuracy of LDA-based GWA calculations. For the lowest valence band width a qualitatively different behavior is observed for medium- and wide-gap materials. The valence band width of medium- (wide-) gap materials is reduced (increased) in EXX(c) compared to the LDA. Quasiparticle corrections lead to a further reduction (increase). As a consequence, EXX(c)-based quasiparticle calculations give valence band widths that are generally 1-2 eV smaller (larger) than experiment for medium- (wide-) gap materials.

Kaur, P

1994-01-01

In 1991, the Family Planning Association (FPA) of the Malaysian state of Perak initiated a community-based development project in the remote Aborigine village of Kampung Tisong. The community consists of approximately 34 households who survive on an average income of about US $37. Malnutrition is pervasive, even minor ailments cause death, more serious afflictions are prevalent, and the closest government clinic is 20 kilometers away and seldom used by the Aborigines. 70% of the children have access to education, but parental illiteracy is a serious educational obstacle. The goals of the FPA program are to 1) promote maternal and child health and responsible parenthood, 2) provide health education, 3) encourage women to seek self-determination, and 4) encourage the development of self-reliance in the community as a whole. The first step was to survey the community's culture, beliefs, and health status with the help of the Aborigines Department and the village headman. After a series of preliminary meetings with other agencies, the FPA began to provide activities including health talks, health courses and demonstrations, medical examinations and check-ups, and first aid training. Environmental protection and sanitation measures were included in the educational activities, and following the traditional "mutual aid system," a small plot of land was cleared for vegetable production. Vegetable gardens and needlecraft will become income-producing activities for the women. Attempts to motivate the women to use family planning have been hindered by the fact that the health of 2 women deteriorated after they began using oral contraceptives. Positive changes are occurring slowly and steadily, however, and the FPA has been instrumental in having the settlement included in a program for the hardcore poor which will provide new housing and farming projects.

People from Minority Ethnic groups tend to present late to dementia services, often in crisis. Culture-specific barriers to help-seeking seem to underlie this. We sought to determine these barriers to timely help-seeking for dementia among people from South Asian backgrounds and what the features of an intervention to overcome them would be. Qualitative study to delineate barriers to and facilitators of help-seeking for South Asian adults with dementia through focus groups and individual interviews. Community settings in and around Greater London. To achieve a maximum variation sample, we purposively recruited 53 English or Bengali speaking South Asian adults without a known diagnosis of dementia through community centres and snowballing. Participants ranged in age from 18 to 83 years, were mostly female and were 60% Bangladeshi. We recruited people from different religions and occupational backgrounds and included those with experience of caring for someone with dementia as well as those without this experience. Participants identified four main barriers to timely diagnosis: barriers to help-seeking for memory problems; the threshold for seeking help for memory problems; ways to overcome barriers to help-seeking; what features an educational resource should have. We have identified the features of an intervention with the potential to improve timely dementia diagnosis in South Asians. The next steps are to devise and test such an intervention.

Full Text Available On October 2013, Pertamina Hulu Energi Offshore North West Java (PHE – ONWJ platform personnel found 93 leaking tubes locations in the finfan coolers/ gas-cooling heat exchanger. After analysis had been performed, the crack in the tube strongly indicate that stress corrosion cracking was occurred by chloride. Chloride stress corrosion cracking (CLSCC is the cracking occurred by the combined influence of tensile stress and a corrosive environment. CLSCC is the one of the most common reasons why austenitic stainless steel pipework or tube and vessels deteriorate in the chemical processing, petrochemical industries and maritime industries. In this thesis purpose to determine the appropriate inspection planning for two main items (tubes and header box in the gas-cooling heat exchanger using risk based inspection (RBI method. The result, inspection of the tubes must be performed on July 6, 2024 and for the header box inspection must be performed on July 6, 2025. In the end, RBI method can be applicated to gas-cooling heat exchanger. Because, risk on the tubes can be reduced from 4.537 m2/year to 0.453 m2/year. And inspection planning for header box can be reduced from 4.528 m2/year to 0.563 m2/year.

Full Text Available The study of the connections among different communities has generated diverse theoretical models and interpretations that were developed to examine the relations of exchange among ancient populations. In general, one may differentiate between theoretical approaches that concentrate specifically on the relations of exchange among distinct communities and areas, and those that analyze the effects of such exchange relationships within the communities. In this study, we focus on the first theoretical approach in order to explore existing exchange relationships from Upper Nubia to Levant, extending through Lower Nubia, Upper Egypt, and Lower Egypt during 3400-3000 B.C., deploying World-Systems Theory and World-Systems Analysis

Evolving hunting practices in Gabon: lessons for community-based conservation interventions

Directory of Open Access Journals (Sweden)

Gretchen Walters

2015-12-01

Full Text Available Addressing today's environmental challenges is intimately linked to understanding and improving natural resource governance institutions. As a result conservation initiatives are increasingly realizing the importance of integrating local perspectives of land tenure arrangements, natural resource rights, and local beliefs into conservation approaches. However, current work has not sufficiently considered the dynamic nature of natural resource governance institutions over time and the potential implications for current conservation interventions. We therefore explored how and why hunting governance has changed since the precolonial period in two ethnic hunting communities in Gabon, Central Africa, integrating various ethnographic methods with resource-use mapping, and a historic literature review. In both communities, hunting governance has undergone significant changes since the precolonial period. A closed-access, lineage-based system of resource use with strict penalties for trespassing, has evolved into a more open-access system, in which the influence of customary governance systems, including magico-political aspects, has declined. These changes have occurred mainly in response to policies and governance structures put in place by the colonial government and postindependence, early state laws. This included a policy of merging villages, the introduction of more modern hunting techniques such as guns and wire cables, and a shift from community to government ownership of the land. Current governance structures are thus the product of a complex mixture of customary, colonial and state influences. These findings suggest that a historical perspective of resource governance, gained through in-depth and long-term engagement with local communities, can provide important insights for community-based conservation approaches, such as helping to identify potential causes and perceptions of environmental change and to design more suitable conservation

Background: Estimates of psychiatric morbidity in the community will help service development. Participation of trained nonspecialist health-care providers will facilitate scaling up of services in resource-limited settings. Aims: This study aimed to estimate the prevalence of priority mental health problems in populations served by the District Mental Health Program (DMHP). Settings and Design: This is a population-based cross-sectional survey. Materials and Methods: We did stratified cluster sampling of households in five districts of Kerala. Trained Accredited Social Health Activists (ASHAs) identified people who had symptoms suggestive of schizophrenia or bipolar disorder. Clinicians evaluated the information collected by the ASHAs and designated individuals as probable cases of psychosis or noncases. Screening instruments such as General Health Questionnaire-12, CAGE questionnaire, and Everyday Abilities Scale for India were used for identifying common mental disorders (CMDs), clinically significant alcohol-related problems, and functional impairment. Results: We found 12.43% of the adult population affected by mental health conditions. We found CMD as most common with a prevalence of 9%. The prevalence of psychosis was 0.71%, clinically significant alcohol-related problems was 1.46%, and dementia and other cognitive impairments was 1.26%. We found informant-based case finding to be useful in the identification of psychosis. Conclusions: Mental health problems are common. Nonspecialist health-care providers can be trained to identify psychiatric morbidity in the community. Their participation will help in narrowing the treatment gap. Embedding operational research to DMHP will make scaling up more efficient. PMID:28827860

Community-based assessment of human rights in a complex humanitarian emergency: the Emergency Assistance Teams-Burma and Cyclone Nargis

2010-04-01

Full Text Available Abstract Introduction Cyclone Nargis hit Burma on May 2, 2008, killing over 138,000 and affecting at least 2.4 million people. The Burmese military junta, the State Peace and Development Council (SPDC, initially blocked international aid to storm victims, forcing community-based organizations such as the Emergency Assistance Teams-Burma (EAT to fill the void, helping with cyclone relief and long-term reconstruction. Recognizing the need for independent monitoring of the human rights situation in cyclone-affected areas, particularly given censorship over storm relief coverage, EAT initiated such documentation efforts. Methods A human rights investigation was conducted to document selected human rights abuses that had initially been reported to volunteers providing relief services in cyclone affected areas. Using participatory research methods and qualitative, semi-structured interviews, EAT volunteers collected 103 testimonies from August 2008 to June 2009; 42 from relief workers and 61 from storm survivors. Results One year after the storm, basic necessities such as food, potable water, and shelter remained insufficient for many, a situation exacerbated by lack of support to help rebuild livelihoods and worsening household debt. This precluded many survivors from being able to access healthcare services, which were inadequate even before Cyclone Nargis. Aid efforts continued to be met with government restrictions and harassment, and relief workers continued to face threats and fear of arrest. Abuses, including land confiscation and misappropriation of aid, were reported during reconstruction, and tight government control over communication and information exchange continued. Conclusions Basic needs of many cyclone survivors in the Irrawaddy Delta remained unmet over a year following Cyclone Nargis. Official impediments to delivery of aid to storm survivors continued, including human rights abrogations experienced by civilians during

The Institute of Medicine (IOM) suggests that linkages between primary care practices and community-based resources can improve health in lower income and minority patients, but examples of these are rare. We conducted a prospective, mixed-methods observational study to identify indicators of primary care-community linkage associated with the frequency of visits to community-based senior centers and improvements in diabetes-related outcomes among 149 new senior center members (72% Hispanic). We used semistructured interviews at baseline and 9-month follow-up, obtaining visit frequency from member software and clinical assessments including hemoglobin A1c (HbA1c) from colocated primary care clinics. Members' discussion of their activities with their primary care providers (PCPs) was associated with increased visits to the senior centers, as well as diabetes-related improvements. Direct feedback from the senior centers to their PCPs was desired by the majority of members and may help to reinforce use of community resources for self-management support.

Getting help quickly: older people and community worker perspectives of contingency planning for falls management.

Science.gov (United States)

Charlton, Kimberly; Murray, Carolyn M; Kumar, Saravana

2018-01-01

Older people living in the community need to plan for getting help quickly if they have a fall. In this paper planning for falls is referred to as contingency planning and is not a falls prevention strategy but rather a falls management strategy. This research explored the perspectives of older people and community workers (CWs) about contingency planning for a fall. Using a qualitative descriptive approach, participants were recruited through a community agency that supports older people. In-depth interviews were conducted with seven older people (67-89 years of age) and a focus group was held with seven workers of mixed disciplines from the same agency. Older people who hadn't fallen were included but were assumed to be at risk of falls because they were in receipt of services. Thematic analysis and concept mapping combined the data from the two participant groups. Four themes including preconceptions about planning ahead for falling, a fall changes perception, giving, and receiving advice about contingency plans and what to do about falling. Both CWs and older people agree contingency planning requires understanding of individual identity and circumstances. CWs have limited knowledge about contingency planning and may be directive, informative, or conservative. Implications for Rehabilitation Falls can result in serious consequences for older people. There is an evidence-practice gap as availability of and access to contingency planning does not necessarily mean older people will use it in a falls emergency. Older people prefer community workers to be directive or informative about contingency planning options but they do want choice and control. Increased community workers knowledge of, and collaborative decision-making about, contingency planning may promote patient-centered services and assist in closing the evidence-practice gap.

In physical therapy, there is increasing focus on the need at the community level to promote health, eliminate disparities in health status, and ameliorate risk factors among underserved minorities. Community-based participatory research (CBPR) is the most promising paradigm for pursuing these goals. Community-based participatory research stresses equitable partnering of the community and investigators in light of local social, structural, and cultural elements. Throughout the research process, the CBPR model emphasizes coalition and team building that joins partners with diverse skills/expertise, knowledge, and sensitivities. This article presents core concepts and principles of CBPR and the rationale for its application in the management of health issues at the community level. Community-based participatory research is now commonly used to address public health issues. A literature review identified limited reports of its use in physical therapy research and services. A published study is used to illustrate features of CBPR for physical therapy. The purpose of this article is to promote an understanding of how physical therapists could use CBPR as a promising way to advance the profession's goals of community health and elimination of health care disparities, and social responsibility. Funding opportunities for the support of CBPR are noted. © 2016 American Physical Therapy Association.

This research attempted to test an HIV prevention intervention for Afro-Caribbean female teens. The purpose was to improve knowledge and attitudes concerning HIV/AIDS, improve mother-daughter sexual communication, and to reduce risky sexual behaviors. Using a community-based approach, sixty mother and daughter pairs were randomly assigned. One condition was experimental using the Making Proud Choices Caribbean Style (MPCCS); another was a comparison of General Health Education. Independent t-tests were used for analysis between the pretest, posttest and 90 days posttests. MPCCS indicated clear usage with other Caribbean teens. This study helped to support the theory when Afro-Caribbean (AC) teens feel they need to become sexually active (subjective norm), and have referent support (parental support), they may blend values, knowledge, and skills (control beliefs), and are likely to make proud choices to reduce risky sexual behavior in minimizing HIV in their communities.

Full Text Available Abstract Although Culturally And Linguistically Diverse (CALD communities participate less in gambling than the general population, those who gamble are more likely to show signs of disordered gambling (Moore and Ohtsuka International Gambling Studies, 1, 87–101, 2001; Raylu and Oei Clinical Psychology Review, 23, 1087–1114, 2004; Yamine and Thomas The impact of gaming on specific cultural groups, Victorian Casino and Gaming Authority, Melbourne, 2000. Research data on gambling problems and interventions in the Arab Australian community are extremely scarce. Therefore, this article will present an overview of the Arab Australian community and cultural issues regarding gambling within the Arab Australian community. Identifying these issues is important to work effectively with Arab Australians clients and those from other CALD backgrounds. The article also presents a conceptual review of peer-reviewed research articles on cultural competence in working with the Arab clients, the overview of Arab migration history to Australia and a summary of recent events that suggest a tension between Arab and non-Arab Australian communities. Observations and experiences that were encountered during the gambling counselling service operating in the Australian Arab community in New South Wales are also discussed. The research data to validate the effectiveness and positive impact of cultural competence are still in its early stages. However, a small number of community education resources have been available for working with the Arab community. From the data in annual reviews on the Arab Council Australia gambling counselling service, it was identified that cultural beliefs and expectations influence risk-taking decisions, identification of gambling issues, and preference of help seeking within the client’s social network. Further, culturally-specific sensitive issues related to political and global security events, which in turn influenced openness and

DNA-based molecular techniques permit the comprehensive determination of microbial diversity but generally do not reveal the relationship between the identity and the function of microorganisms. The first direct molecular technique to enable the linkage of phylogeny with function is DNA-based stable isotope probing (DNA-SIP). Applying this method first helped describe the utilization of simple compounds, such as methane, methanol or glucose and has since been used to detect microbial communities active in the utilization of a wide variety of compounds, including various xenobiotics. The principle of the method lies in providing 13C-labeled substrate to a microbial community and subsequent analyses of the 13C-DNA isolated from the community. Isopycnic centrifugation permits separating 13C-labeled DNA of organisms that utilized the substrate from 12C-DNA of the inactive majority. As the whole metagenome of active populations is isolated, its follow-up analysis provides successful taxonomic identification as well as the potential for functional gene analyses. Because of its power, DNA-SIP has become one of the leading techniques of microbial ecology research. But from other point of view, it is a labor-intensive method that requires careful attention to detail during each experimental step in order to avoid misinterpretation of results.

Charting a path forward: building AGU's capacity to help foster scientist-decision maker engagement

Most research proposals, papers, and presentation abstracts begin with the motivation that the new science presented will benefit society. Behind this, beyond making good on the promises to get funding, is a sincere effort to contribute our knowledge and talent to build a better (safer, sustainable, more resilient) world. For this to happen, however, the science needs to be connected to people in communities who make decisions. While this happens in a variety of ways, often for research to be most useful to society, engagement with decision makers should occur at the beginning and throughout the research process. Increasingly this is being recognized as important, as evidenced by the growing number of boundary organizations (e.g., U.S. Department of the Interior's Climate Science Centers, NOAA's Regional Integrated Sciences and Assessment programs). Even within AGU, in recent years there has been a number of new activities and networks that suggest a growing community of practice for those doing work at the science-society interface (e.g., The Thriving Earth Exchange, the Water and Society Technical Committee in the Hydrology Section). In this presentation, we highlight what these activities are and share insights from those involved. We evaluate trends (e.g., have the number of abstracts on this topic increased?) and present responses from AGU members to questions on where this community of practice should go next (e.g., What is the most important task the AGU community should do to improve decision maker-scientist engagement?). The goal of this presentation is to promote a conversation about how the AGU community can be better prepared to foster engagement with decision makers that will lead to more actionable science. This will help us ensure our science is useful to society, fulfilling our motivations, and arguably responsibilities, both individually and as a community. It will also serve to prepare new scientists for a broader range of careers beyond

Addressing the nation's increasingly complex public health challenges will require more effective multisector collaboration and stronger public health leadership. In 2005, the Healthy Wisconsin Leadership Institute launched an annual, year-long intensive "community teams" program. The goal of this program is to develop collaborative leadership and public health skills among Wisconsin-based multisectoral teams mobilizing their communities to improve public health. To measure the scope of participation and program impacts on individual learning and practice, including application of new knowledge and collective achievements of teams on coalition and short-term community outcomes. End-of-year participant program evaluations and follow-up telephone interviews with participants 20 months after program completion. Community-based public health leadership training program. Sixty-eight participants in the Community Teams Program during the years 2006 to 2007 and 2007 to 2008. Professional diversity of program participants; individual learning and practice, including application of new knowledge; and collective achievements of teams, including coalition and short-term community outcomes. Participants in the Community Teams Program represent a diversity of sectors, including nonprofit, governmental, academic, business, and local public health. Participation increased knowledge across all public health and leadership competency areas covered in the program. Participating teams reported outcomes, including increased engagement of community leadership, expansion of preventive services, increased media coverage, strengthened community coalitions, and increased grant funding. Evaluation of this community-based approach to public health leadership training has shown it to be a promising model for building collaborative and public health leadership skills and initiating sustained community change for health improvement.

2015-01-01

Background Previous studies of problem Internet gamblers have failed to distinguish whether their problem gambling relates to Internet or land-based gambling modes. Therefore, characteristics and help-seeking behaviors of people whose gambling problems relate specifically to Internet gambling are unknown, but could inform the optimal alignment of treatment and support services with the needs and preferences of problem gamblers. Objective This study aimed to compare (1) characteristics of problem Internet gamblers and problem land-based gamblers and (2) uptake of different types and modes of help between problem Internet gamblers and problem land-based gamblers. Hypothesis 1 was that problem Internet gamblers are less likely to seek help. Hypothesis 2 was that problem Internet gamblers are more likely to use online modes of help. Methods A sample of 620 respondents meeting criteria for problem gambling was drawn from an online survey of 4594 Australian gamblers. Respondents were recruited through advertisements on gambling and gambling help websites, Facebook, and Google. Measures consisted of gambling participation; proportion of gambling on the Internet; most problematic mode of gambling; help seeking from 11 different sources of formal help, informal help, and self-help for gambling problems; psychological distress (Kessler 6); problem gambling severity (Problem Gambling Severity Index, PGSI); and demographics. Results Problem Internet gamblers were significantly more likely than problem land-based gamblers to be male (χ2 1=28.3, Pgambling helplines, online groups, self-exclusion from land-based venues, family or friends, and self-help strategies. Both problem Internet and problem land-based gamblers had similarly low use of online help. However, problem land-based gamblers (37.6%, 126/335) were significantly more likely to have sought land-based formal help compared to problem Internet gamblers (23.5%, 67/285; χ2 1=14.3, Pgambling help by problem Internet

This study aims to investigate the contribution of cultural resources to Community-Based Integrative Care (CBIC), to consolidate it as a model of community-based mental health and a political strategy for local health, and to identify the cultural strategies most used in CBIC sessions. This is a qualitative study, conducted in the city of João Pessoa, state of Paraíba, Brazil, with ten therapists. We used semi-structured interviews and afield diary, from September, 2008, to March, 2009, then proceeded to the interpretive analysis of the data. It was evident that the inclusion of cultural resources contributes to the consolidation of CBIC, for it reclaims and strengthen values, and it underscores the personal and social identity of individuals, encouraging effective participation. The main cultural resources used were music, dynamics and prayers. The conclusion was that cultural resources are an important resource for the work of the therapist, for it strengthens bonds and helps people to give a new meaning to their suffering.

Genome-driven evolutionary game theory helps understand the rise of metabolic interdependencies in microbial communities.

Metabolite exchanges in microbial communities give rise to ecological interactions that govern ecosystem diversity and stability. It is unclear, however, how the rise of these interactions varies across metabolites and organisms. Here we address this question by integrating genome-scale models of metabolism with evolutionary game theory. Specifically, we use microbial fitness values estimated by metabolic models to infer evolutionarily stable interactions in multi-species microbial "games". We first validate our approach using a well-characterized yeast cheater-cooperator system. We next perform over 80,000 in silico experiments to infer how metabolic interdependencies mediated by amino acid leakage in Escherichia coli vary across 189 amino acid pairs. While most pairs display shared patterns of inter-species interactions, multiple deviations are caused by pleiotropy and epistasis in metabolism. Furthermore, simulated invasion experiments reveal possible paths to obligate cross-feeding. Our study provides genomically driven insight into the rise of ecological interactions, with implications for microbiome research and synthetic ecology.

Community-based rehabilitation can help to maximize function following acquired brain injury (ABI); however, data on treatment outcome is limited in quantity. To describe and evaluate client outcomes of an outpatient programme for adults with moderate-to-severe traumatic and non-traumatic ABI. Two phase design involving retrospective and longitudinal study of programme completers with ABI (n = 47). Changes in functioning were measured with the Mayo-Portland Inventory (MPAI-4), administered pre- and immediately post-rehabilitation and at 3 years follow-up. Self-ratings were supplemented with MPAI-4 data from significant others (n = 32) and staff (n = 32). Injured individuals and informants reported improved physical and psychosocial functioning immediately following the completion of community rehabilitation, with medium-to-large and significant treatment gains noted on the MPAI-4 ability, adjustment and participation sub-scales (Cohen's d range = 0.31-1.10). A deterioration in individuals' adjustment was further reported at follow-up, although this was based on limited data. Issues with longer-term rehabilitation service provision were additionally noted. The data support the need for continuity of care, including ongoing emotional support, to cater to the complex and dynamic needs of the ABI population. However, these results need to be considered in the context of a small sample size and quasi-experimental design.

Emergency department leaders at DCH Regional Medical Center in Tuscaloosa, AL, and Cullman Regional Medical Center in Cullman, AL, credit their regular practice drills with helping them deal with unprecedented demand when deadly tornadoes swept through the South this past April. Both facilities used the hospital instant command structure (HICS) to mobilize the resources needed to care for the surge in patients, and say the approach worked well in helping them meet the needs of their communities. However, the crises also showcased opportunities for improvement. The ED at DCH Regional Medical Center saw more than 600 patients on the day of the storm, a three-fold increase in the hospital's typical volume. CRMC treated 99 patients in the seven hours immediately following the storm when it usually treats 114 patients per day. In addition to a big surge in patients, both hospitals dealt with power outages that limited access to some services such as radiology. Triage proved particularly challenging at DCH Regional Medical Center, as patients flowed into the hospital from numerous access points. The hospital plans to assign coordinators to each area of the hospital to better manage the influx in the future. When reviewing emergency operations plans, Joint Commission reviewers often find deficiencies in hazard vulnerability analyses as well as the processes used to determine the emergency credentials of licensed independent practitioners.

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

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

Although asthma self-management plans are widely recommended as essential in the long-term treatment of adult asthma, there have been few studies examining their use. Our objective was to assess the effect of a "credit card" adult asthma self-management plan in a community experiencing major health problems from asthma, by means of a before and after intervention trial of the efficacy of the "credit card" plan, when introduced through community-based asthma clinics. The participants were 69 Maori people with asthma. The "credit card" plan consisted of written guidelines for the self-management of asthma, based on self-assessment of asthma severity, printed on a plastic card. On one side, management guidelines were based on the interpretation of peak expiratory flow rate (PEFR) recordings, whilst the reverse side was based on symptoms. The outcome measures used were before and after comparison of markers of asthma morbidity and requirement for acute medical treatment; and a structured questionnaire assessing the acceptability and use of the credit card plan. Following the introduction of the plan, the mean PEFR increased from 347 to 389 l.min-1, the percentage of nights woken fell from 30.4 to 16.9%, and the number of days "out of action" fell from 3.8 to 1.7%. The requirements for acute medical treatment also fell during the intervention period. Most participants commented favourably on the content and usefulness of the plan. In the situation of worsening asthma, 28% of subjects found the peak flow side of the card most helpful, 7% the symptoms side, and 48% found both sides equally helpful.(ABSTRACT TRUNCATED AT 250 WORDS)

Adaptive capacity and community-based natural resource management.

Science.gov (United States)

Armitage, Derek

2005-06-01

Why do some community-based natural resource management strategies perform better than others? Commons theorists have approached this question by developing institutional design principles to address collective choice situations, while other analysts have critiqued the underlying assumptions of community-based resource management. However, efforts to enhance community-based natural resource management performance also require an analysis of exogenous and endogenous variables that influence how social actors not only act collectively but do so in ways that respond to changing circumstances, foster learning, and build capacity for management adaptation. Drawing on examples from northern Canada and Southeast Asia, this article examines the relationship among adaptive capacity, community-based resource management performance, and the socio-institutional determinants of collective action, such as technical, financial, and legal constraints, and complex issues of politics, scale, knowledge, community and culture. An emphasis on adaptive capacity responds to a conceptual weakness in community-based natural resource management and highlights an emerging research and policy discourse that builds upon static design principles and the contested concepts in current management practice.

Several forms of carbon-based magnetic materials, i.e. single radicals, radical dimers, and alternating stacks of radicals and diamagnetic molecules, have been investigated using density-functional theory with dispersion correction and full geometry optimization. Our calculated results demonstrate that the C{sub 31}H{sub 15} (R{sub 4}) radical has a spin of ½. However, in its [R{sub 4}]{sub 2} dimer structure, the net spin becomes zero due to antiferromagnetic spin-exchange between radicals. To avoid antiferromagnetic spin-exchange of identical face-to-face radicals, eight alternating stacks, R{sub 4}/D{sub 2m}/R{sub 4} (with m = 3-10), were designed. Our calculated results show that charge transfer (Δn) between R{sub 4} radicals and the diamagnetic molecule D{sub 2m} occurs with a mechanism of spin exchange (J) in stacks. The more electrons that transfer from R{sub 4} to D{sub 2m}, the stronger the ferromagnetic spin-exchange in stacks. In addition, our calculated results show that Δn can be tailored by adjusting the electron affinity (E{sub a}) of D{sub 2m}. The correlation between Δn, E{sub a}, m, and J is discussed. These results give some hints for the design of new ferromagnetic carbon-based materials.

Variability in benthic exchange rate, depth, and residence time beneath a shallow coastal estuary

Hydrodynamically-driven exchange of water between the water column and shallow seabed aquifer, benthic exchange, is a significant and dynamic component of coastal and estuarine fluid budgets, but wave-induced benthic exchange has not been measured in the field. Mixing between surface water and groundwater solutes promotes ecologically important chemical reactions, so quantifying benthic exchange rates, depths, and residence times, constrains estimates of coastal chemical cycling. In this study, we present the first field-based direct measurements of wave-induced exchange and compare it to exchange induced by the other primary drivers of exchange - tides, and currents. We deployed instruments in a shallow estuary to measure benthic exchange and temporal variability over an 11-day period. Differential pressure sensors recorded pressure gradients across the seabed, and up-and down-looking ADCPs recorded currents and pressures from which wave parameters, surface-water currents, and water depth were determined. Wave-induced exchange was calculated directly from 1) differential pressure measurements, and indirectly with an analytical solution based on wave parameters from 2) ADCP and 3) weather station data. Groundwater flow models were used to assess the effects of aquifer properties on benthic exchange depth and residence time. Benthic exchange driven by tidal pumping or current-bedform interaction was calculated from tidal stage variation and from ADCP-measured currents at the bed, respectively. Waves were the primary benthic exchange driver (average = 20.0 cm/d, maximum = 92.3 cm/d) during the measurement period. Benthic exchange due to tides (average = 3.7 cm/d) and current-bedform interaction (average = 6.5x10-2 cm/d) was much lower. Wave-induced exchange calculated from pressure measurements and ADCP-measured wave parameters matched well, but wind-based rates underestimated wave energy and exchange. Groundwater models showed that residence time and depth increased

A method to determine soil exchangeable calcium (Ca), magnesium (Mg), potassium (K), and sodium (Na) by using atomic absorption spectrophotometer (AAS) and extraction with ammonium acetate was developed. Results showed that the accuracy of exchangeable base cation data with AAS method fits well with the national standard referential soil data. The relative errors for parallel samples of exchangeable Ca and Mg with 66 pair samples ranged from 0.02%-3.14% and 0.06%-4.06%, and averaged to be 1.22% and 1.25%, respectively. The relative errors for exchangeable K and Na with AAS and flame photometer (FP) ranged from 0.06%-8.39% and 0.06-1.54, and averaged to be 3.72% and 0.56%, respectively. A case study showed that the determination method for exchangeable base cations by using AAS was proven to be reliable and trustable, which could reflect the real situation of soil cation exchange properties in farmlands.

Effects of introduction of new resources and fragmentation of existing resources on limiting wealth distribution in asset exchange models

Science.gov (United States)

Ali Saif, M.; Gade, Prashant M.

2009-03-01

Pareto law, which states that wealth distribution in societies has a power-law tail, has been the subject of intensive investigations in the statistical physics community. Several models have been employed to explain this behavior. However, most of the agent based models assume the conservation of number of agents and wealth. Both these assumptions are unrealistic. In this paper, we study the limiting wealth distribution when one or both of these assumptions are not valid. Given the universality of the law, we have tried to study the wealth distribution from the asset exchange models point of view. We consider models in which (a) new agents enter the market at a constant rate (b) richer agents fragment with higher probability introducing newer agents in the system (c) both fragmentation and entry of new agents is taking place. While models (a) and (c) do not conserve total wealth or number of agents, model (b) conserves total wealth. All these models lead to a power-law tail in the wealth distribution pointing to the possibility that more generalized asset exchange models could help us to explain the emergence of a power-law tail in wealth distribution.

Full Text Available This article addresses macroeconomic instabilities according to exchange rate regimes in Sub-Saharan Africa (SSA. Based on International Monetary Fund's exchange rate regimes de facto classification, the global sample, SSA, is first divided into two subsamples, which are countries within CFA franc zone (ZCFA and those outside CFA franc zone (HZCFA, and then into four categories, which are the Western Economic and Monetary Union (WAEMU, the Central African Economic and Monetary Community, the countries CFA franc zone with fix exchange rate regimes(HZCFA-FIX, and the countries outside CFA franc zone with flexible exchange rate regimes(HZCFA-FLEX. By applying advanced statistical and econometric methods upon internal and external macroeconomic equilibrium conditions, we show that the inflation, the GDP (or the output and the real exchange rate (RER are very volatile in SSA. However, we found out that they are more volatile in the group HZCFA comparatively to the group ZCFA. We also found out that they are higher in the group HZCFA-FIX than the group HZCFA-FLEX. Moreover, we found out that a high instability of the inflation is combined with those of the output and the RER.

Based on the localized nature of density matrix, the exchange hole is divided into the short-range (SR) and long-range (LR) parts by using an adequate filter function, where the LR part is deduced by matching of moments with the exactly calculated SR counterpart, ensuring the correct asymptotic -1/r behavior of the exchange potential. With this division, the time-consuming integration is truncated at a certain interaction range, largely reducing the computation cost. The total energies, exchange energies, exchange potentials, and eigenvalues of the highest-occupied orbitals are calculated for the noble-gas atoms. The close agreement of the results with the exact values suggests the validity of the approximation.

Health reform is helping to transform the health insurance marketplace and facilitate new opportunities to reevaluate and restructure the underlying framework of employer-sponsored benefits. Central to these opportunities is the emergence of public health exchanges at the state and federal levels offering a coordinated platform of diverse designs and health plans available on a guaranteed issue basis and often with government-provided subsidies. Parallel and complementary to this trend is the emergence of private health exchanges that similarly offer a diversity of plans on a variety of bases. This article shows why, together, these offerings provide potential streamlined solutions for employers as they reevaluate how they facilitate and support access to affordable coverage for their employees (and retirees).

Sustaining collaborations between community-based organization leaders and academic researchers in community-engaged research (CEnR) in the service of decreasing health inequities necessitates understanding the collaborations from an inter-organizational perspective. We assessed the perspectives of community leaders and university-based researchers conducting community-engaged research in a medium-sized city with a history of community-university tension. Our research team, included experts in CEnR and organizational theory, used qualitative methods and purposeful, snowball sampling to recruit local participants and performed key informant interviews from July 2011-May 2012. A community-based researcher interviewed 11 community leaders, a university-based researcher interviewed 12 university-based researchers. We interviewed participants until we reached thematic saturation and performed analyses using the constant comparative method. Unifying themes characterizing community leaders and university-based researchers' relationships on the inter-organizational level include: 1) Both groups described that community-engaged university-based researchers are exceptions to typical university culture; 2) Both groups described that the interpersonal skills university-based researchers need for CEnR require a change in organizational culture and training; 3) Both groups described skepticism about the sustainability of a meaningful institutional commitment to community-engaged research 4) Both groups described the historical impact on research relationships of race, power, and privilege, but only community leaders described its persistent role and relevance in research relationships. Challenges to community-academic research partnerships include researcher interpersonal skills and different perceptions of the importance of organizational history. Solutions to improve research partnerships may include transforming university culture and community-university discussions on race

Full Text Available This study aims to investigate the use of information and communication technology (ICT to support knowledge exchange in project-based organisations. The primary ICT tool investigated in this research is WhatsApp, a messaging application that has been widely used since its introduction. An ethnographic case study method was utilised to analyse qualitative data collected from interviews and focus group discussions. Three projects in an Indonesian university with a duration ranging from 8 months to 2 years were examined as object of investigations. Broadly, the findings show that ICT tools are generally useful in supporting knowledge exchange, which ultimately positively affects project performance. The project teams relied on WhatsApp for the success of the projects. Although face-to-face meetings were rare, team communication was highly intensive, supported by WhatsApp. In addition, managers are encouraged to promote knowledge exchange between team members. Through knowledge exchange, there will be knowledge development, which facilitates the invention of new techniques and methods for promoting project success. The most prominent findings are presented using direct quotations to provide first hand insight from the field. At the end of the paper, recommendations regarding what project managers should do during and after the project has been completed are presented. The recommendations are classified based on the knowledge management life cycle, representing a structured method to manage knowledge in project-based organisations.

Strength training (ST) is an important health behavior for aging women; it helps maintain strength and function and reduces risk for chronic diseases. This study assessed change in physical fitness following participation in a ST program implemented and evaluated by community leaders. The StrongWomen Program is a nationally disseminated, research-based, community ST program active in 40 states. The Senior Fitness Test is used to assess upper and lower body strength, upper and lower body flexibility, aerobic fitness, and agility; data are collected prior to and following program participation. For these analyses, five states provided deidentified data for 367 female participants, mean age 63 (±11) years. Attendance in approximately 10 weeks of twice-weekly classes was 69.4%. Paired t tests were used to analyze pre-post change. Significant improvements were observed (p age-group and compared with published, age-based norms. This study demonstrates that it is feasible for community leaders to conduct pre-post physical fitness evaluations with participants and that participants experienced improvements across several important domains of physical fitness.

Deogade, Suryakant C; Naitam, Dinesh

2016-01-01

Community-based dental education (CBDE) is the implementation of dental education in a specific social context, which shifts a substantial part of dental clinical education from dental teaching institutional clinics to mainly public health settings. Dental students gain additional value from CBDE when they are guided through a reflective process of learning. We propose some key elements to the existing CBDE program that support meaningful personal learning experiences. Dental rotations of 'externships' in community-based clinical settings (CBCS) are year-long community-based placements and have proven to be strong learning environments where students develop good communication skills and better clinical reasoning and management skills. We look at the characteristics of CBDE and how the social and personal context provided in communities enhances dental education. Meaningfulness is created by the authentic context, which develops over a period of time. Structured reflection assignments and methods are suggested as key elements in the existing CBDE program. Strategies to enrich community-based learning experiences for dental students include: Photographic documentation; written narratives; critical incident reports; and mentored post-experiential small group discussions. A directed process of reflection is suggested as a way to increase the impact of the community learning experiences. We suggest key elements to the existing CBDE module so that the context-rich environment of CBDE allows for meaningful relations and experiences for dental students and enhanced learning.

2016-01-01

The primary objective of the Phase Change HX payload on the International Space Station (ISS) is to test and demonstrate the viability and performance of Phase Change Material Heat Exchangers (PCM HX). The system was required to pump a working fluid through a PCM HX to promote the phase change material to freeze and thaw as expected on Orion's Multipurpose Crew Vehicle. Due to limitations on ISS's Internal Thermal Control System, a heat pump was needed on the Phase Change HX payload to help with reducing the working fluid's temperature to below 0degC (32degF). This paper will review the design and development of a TEC based liquid-liquid heat exchanger as a way to vary to fluid temperature for the freeze and thaw phase of the PCM HX. Specifically, the paper will review the design of custom coldplates and sizing for the required heat removal of the HX.

The development of a temperature and humidity control system that can remove heat and recover water vapor is key to the development of an Environmental Control and Life Support System (ECLSS). Large quantities of water vapor must be removed from air, and this operation has proven difficult in the absense of gravity. This paper presents the modeling results from a program to develop a novel membrane-based heat exchanger known as the condensate recovery heat exchanger (CRX). This device cools and dehumidifies humid air and simultaneously recovers water-vapor condensate. In this paper, the CRX is described and the results of an analysis of the heat- and mass-transfer characteristics of the device are given.

Relationship of field-theory based single-boson-exchange potentials to static ones

Amghar, A.; Desplanques, B.

2000-01-01

It is shown that field-theory based single-boson-exchange potentials cannot be identified to those of the Yukawa or Coulomb type that are currently inserted in the Schroedinger equation. The potential which is obtained rather correspond to this current single-boson-exchange potential corrected for the probability that the system under consideration is in a two-body component, therefore missing contributions due to the interaction of these two bodies while bosons are exchanged. The role of these contributions, which involve at least two-boson exchanges, is examined. The conditions that allow one to recover the usual single-boson-exchange potential are given. It is shown that the present results have some relation: (i) to the failure of the Bethe-Salpeter equation in reproducing the Dirac or Klein-Gordon equations in the limit where one of the constituents has a large mass, (ii) to the absence of corrections of relative order α log 1/α to a full calculation of the binding energy in the case of neutral massless bosons or (iii) to large corrections of wave-functions calculated perturbatively in some light-front approaches.

Large-scale restoration programmes in the tropics require large volumes of high quality, genetically diverse and locally adapted seeds from a large number of species. However, scarcity of native seeds is a critical restriction to achieve restoration targets. In this paper, we analyse three successful community-based networks that supply native seeds and seedlings for Brazilian Amazon and Cerrado restoration projects. In addition, we propose directions to promote local participation, legal, technical and commercialisation issues for up-scaling the market of native seeds for restoration with high quality and social justice. We argue that effective community-based restoration arrangements should follow some principles: (i) seed production must be based on real market demand; (ii) non-governmental and governmental organisations have a key role in supporting local organisation, legal requirements and selling processes; (iii) local ecological knowledge and labour should be valued, enabling local communities to promote large-scale seed production; (iv) applied research can help develop appropriate techniques and solve technical issues. The case studies from Brazil and principles presented here can be useful for the up-scaling restoration ecology efforts in many other parts of the world and especially in tropical countries where improving rural community income is a strategy for biodiversity conservation and restoration. © 2018 German Society for Plant Sciences and The Royal Botanical Society of the Netherlands.

A continuous exchange factor method for analysis of radiative exchange in enclosures is developed. In this method two types of exchange functions are defined, direct exchange function and total exchange function. Certain integral equations relating total exchange functions to direct exchange functions are developed. These integral equations are solved using Gaussian quadrature integration method. The results obtained based on the present approach are found to be more accurate than those of the zonal method

Developing Community-Based Rehabilitation Programs for Musculoskeletal Diseases in Low-Income Areas of Mexico: The Community-Based Rehabilitation for Low-Income Communities Living With Rheumatic Diseases (CONCORD) Protocol

Science.gov (United States)

2014-01-01

Background The negative impact of musculoskeletal diseases on the physical function and quality of life of people living in developing countries is considerable. This disabling effect is even more marked in low-socioeconomic communities within developing countries. In Mexico, there is a need to create community-based rehabilitation programs for people living with musculoskeletal diseases in low-socioeconomic areas. These programs should be directed to prevent and decrease disability, accommodating the specific local culture of communities. Objective The objective of this paper is to describe a research protocol designed to develop, implement, and evaluate culturally sensitive community-based rehabilitation programs aiming to decrease disability of people living with musculoskeletal diseases in two low-income Mexican communities. Methods A community-based participatory research approach is proposed, including multi and transdisciplinary efforts among the community, medical anthropology, and the health sciences. The project is structured in 4 main stages: (1) situation analysis, (2) program development, (3) program implementation, and (4) program evaluation. Each stage includes the use of quantitative and qualitative methods (mixed method program). Results So far, we obtained resources from a Mexican federal agency and completed stage one of the project at Chankom, Yucatán. We are currently receiving funding from an international agency to complete stage two at this same location. We expect that the project at Chankom will be concluded by December of 2017. On the other hand, we just started the execution of stage one at Nuevo León with funding from a Mexican federal agency. We expect to conclude the project at this site by September of 2018. Conclusions Using a community-based participatory research approach and a mixed method program could result in the creation of culturally sensitive community-based rehabilitation programs that promote community development and

Noncommunicable diseases (NCD) are the most common causes of morbidity and mortality worldwide, even in low- and middle-income countries (LMIC). Recent trends in health promotion emphasize community-based interventions as an important strategy for improving health outcomes. The aim of this study was to conduct formative research regarding the perceptions of NCD risk factors, their influencing factors, and community resources available to aid the development and implementation of a community-based intervention with school-age children. Focus group discussions (n = 18), home visits (n = 30), and individual semi-structured interviews (n = 26) were conducted in three urban communities in Guatemala with school-age children (10-12 years of age), teachers, parents, and local community members (i.e., school principals, school food kiosk vendors, religious leaders, authority representatives). All focus groups and interviews were transcribed verbatim for thematic analysis. Children, parents, and teachers have general knowledge about modifiable risk factors. Adults worried more about tobacco use, as compared to unhealthy diet and physical inactivity in children. Participants identified features at the intrapersonal (e.g., negative emotional state), interpersonal (e.g., peers as role models), and organizational and community levels (e.g., high levels of crime) that influence these risk factors in children. School committees, religious leaders, and government programs and activities were among the positive community resources identified. These findings should help researchers in Guatemala and similar LMIC to develop community-based interventions for NCD prevention in school-age children that are effective, feasible, and culturally acceptable.

Preparation of a strong cation exchange membrane by radiation grafting of styrene on to polyethylene (LDPE) film by mutual irradiation technique in the presence of air followed by sulfonation is described. The grafting has been carried out in the presence of air and without any additive. Low dose rate has been seen to facilitate the grafting. Further higher the grafting percentage more is the exchange capacity. The addition of a swelling agent during the sulfonation helped in achieving the high exchange capacity. The TGA-MASS analysis confirmed the grafting and the sulfonation. (author)

Transferring knowledge and know-how from the nuclear power community to the research reactor community

Wijtsma, F.J.

2002-01-01

Question What is the best way of transferring knowledge and know-how from the nuclear power community to the research reactor community, e.g. in the fields of quality assurance, safety culture, etc.? To answer the question on how to transfer knowledge and know-how from the nuclear power community to the research reactor community, one should first try to establish what are the differences and similarities between these types of nuclear facilities. Despite the big difference between the primary objectives of these two kinds of facilities, i.e. electricity production versus providing irradiation services, the underlying safety culture should be comparable. For historical reasons, nuclear power plant management took the lead in establishing fully accepted safety standards. However, research reactors can avail themselves of the wide body of nuclear safety experience accumulated at nuclear power plants. This should be applicable to all nuclear facilities. Nonetheless, in transferring their know-how, safety specialists should take into account the huge differences between critical assemblies, university reactors, small research reactors and multi-purpose high power research reactors. The goal to which a specific facility is dedicated bears heavily upon the outlook of its management Question: How can well run research reactors help problem research reactors? To answer this, a basic question should in turn be posed: Should one help a research reactor with operational difficulties? And, if so, to what extent? Who will benefit? Within the framework of this meeting, one should concentrate on nuclear safety, which is determined by: Safety culture (including quality assurance); The level of training of all staff; Ageing (installation, staff and documentation); The front/back end of the fuel cycle; A strong programme versus extended shutdown; Regulatory (nuclear regulatory) inspectorates; National (international) co-operation; The financial situation prevailing at the

Where and why hyporheic exchange is important: Inferences from a parsimonious, physically-based river network model

Science.gov (United States)

Gomez-Velez, J. D.; Harvey, J. W.

2014-12-01

Hyporheic exchange has been hypothesized to have basin-scale consequences; however, predictions throughout river networks are limited by available geomorphic and hydrogeologic data as well as models that can analyze and aggregate hyporheic exchange flows across large spatial scales. We developed a parsimonious but physically-based model of hyporheic flow for application in large river basins: Networks with EXchange and Subsurface Storage (NEXSS). At the core of NEXSS is a characterization of the channel geometry, geomorphic features, and related hydraulic drivers based on scaling equations from the literature and readily accessible information such as river discharge, bankfull width, median grain size, sinuosity, channel slope, and regional groundwater gradients. Multi-scale hyporheic flow is computed based on combining simple but powerful analytical and numerical expressions that have been previously published. We applied NEXSS across a broad range of geomorphic diversity in river reaches and synthetic river networks. NEXSS demonstrates that vertical exchange beneath submerged bedforms dominates hyporheic fluxes and turnover rates along the river corridor. Moreover, the hyporheic zone's potential for biogeochemical transformations is comparable across stream orders, but the abundance of lower-order channels results in a considerably higher cumulative effect for low-order streams. Thus, vertical exchange beneath submerged bedforms has more potential for biogeochemical transformations than lateral exchange beneath banks, although lateral exchange through meanders may be important in large rivers. These results have implications for predicting outcomes of river and basin management practices.

The severity of the financial crisis that occurred in Indonesia required an early warning system of financial crisis. The financial crisis in Indonesia can be detected based on imports, exports, and foreign exchange reserves. The purpose of the research is to determine an appropriate model to detect the financial crisis in Indonesia based on imports, exports, and foreign exchange reserves. Markov switching is an alternative framework for the approach often used in financial crisis detection. Combined volatility and Markov switching model with three states assumptions can be established if an AR and volatility models have been obtained. Imports, exports, and foreign exchange reserves data from January 1990 to December 2016 have the heteroscedasticity effect so that an ARCH model is used as a volatility model. Research shows that SWARCH(3.1) model is an appropriate model for detecting financial crisis in Indonesia based on imports, exports, and foreign exchange reserves.

Community engagement is an on-going, arduous, and necessary process for developing effective health promotion programs. The challenges are amplified when the particular health issue or research question is not prominent in the consciousness of the targeted community. In this paper, we explore the community-based participatory research (CBPR) model as a means to negotiate a mutual agenda between communities and researchers. The paper is focused on the (perceived) need for cervical cancer screening in an under-resourced community in Cape Town, South Africa. Cervical cancer is a significant health problem in this community and elsewhere in South Africa. Unlike HIV-AIDS, however, many Black South Africans have not been educated about cervical cancer and the importance of obtaining screening. Many may not consider screening a priority in their lives. Our research included extensive consultations and informal interviews with diverse community and regional stakeholders. Following these, we conducted 27 focus groups and 106 demographic surveys with randomly selected youth, parents, local health care personnel, educators and school staff. Focus group data were summarized and analyzed cross-sectionally. Community stakeholders were involved throughout this research. Our consultations, interviews, and focus group data were key in identifying the concerns and priorities of the community. By engaging community stakeholders, we developed a research framework that incorporated the community's concerns and priorities, and stressed the intersecting roles of poverty, violence, and other cultural forces in shaping community members' health and wellbeing. Community members helped to refocus our research from cervical cancer to 'cervical health,' a concept that acknowledged the impact on women's bodies and lives of HIV-AIDS and STDs, sexual violence, poverty, and multiple social problems. We conclude that the research agenda and questions in community-based health research should not be

Hydrodynamically driven benthic exchange of water between the water column and shallow seabed aquifer is a significant and dynamic component of coastal and estuarine fluid budgets. Associated exchange of solutes promotes ecologically important chemical reactions, so quantifying benthic exchange rates, depths, and residence times constrains coastal chemical cycling estimates. We present the first combined field, numerical, and analytical modeling investigation of wave-induced exchange. Temporal variability of exchange was calculated with data collected by instruments deployed in a shallow estuary for 11 days. Differential pressure sensors recorded pressure gradients across the seabed, and up- and down-looking ADCPs recorded currents and pressures to determine wave parameters, surface-water currents, and water depth. Wave-induced exchange was calculated (1) directly from differential pressure measurements, and indirectly with an analytical model based on wave parameters from (2) ADCP and (3) wind data. Wave-induced exchange from pressure measurements and ADCP-measured wave parameters matched well, but both exceeded wind-based values. Exchange induced by tidal pumping and current-bed form interaction—the other primary drivers in shallow coastal waters were calculated from tidal stage variation and ADCP-measured currents. Exchange from waves (mean = 20.0 cm/d; range = 1.75-92.3 cm/d) greatly exceeded exchange due to tides (mean = 3.7 cm/d) and current-bed form interaction (mean = 6.5 × 10-2 cm/d). Groundwater flow models showed aquifer properties affect wave-driven benthic exchange: residence time and depth increased and exchange rates decreased with increasing hydraulic diffusivity (ratio of aquifer permeability to compressibility). This new understanding of benthic exchange will help managers assess its control over chemical fluxes to marine systems.

Laboratory tests were performed to examine the efficacy of mixed nitric/hydrofluoric acid followed by mixed nitric/oxalic acid leach treatments to decontaminate ion exchange materials that have been found in a number of samples retrieved from K East (KE)Basin sludge. The ion exchange materials contain organic ion exchange resins and zeolite inorganic ion exchange material. Based on process records, the ion exchange resins found in the K Basins is a mixed-bed, strong acid/strong base material marketed as Purolite NRW-037. The zeolite material is Zeolon-900, a granular material composed of the mineral mordenite. Radionuclides sorbed or associated with the ion exchange material can restrict its disposal to the Environmental Restoration Disposal Facility (ERDF). The need for testing to support development of a treatment process for K Basin sludge has been described in Section 4.2 of ''Testing Strategy to Support the Development of K Basins Sludge Treatment Process'' (Flament 1998). Elutriation and washing steps are designed to remove the organic resins from the K Basin sludge. To help understand the effects of the anticipated separation steps, tests were performed with well-rinsed ion exchange (IX) material from KE Basin floor sludge (sample H-08 BEAD G) and with well-rinsed IX having small quantities of added KE canister composite sludge (sample KECOMP). Tests also were performed to determine the relative quantities of organic and inorganic IX materials present in the H-08 K Basin sludge material. Based on chemical analyses of the separated fractions, the rinsed and dry IX material H-08 BEAD G was found to contain 36 weight percent inorganic material (primarily zeolite). The as-received (unrinsed) and dried H-08 material was estimated to contain 45 weight percent inorganic material

Corlette, Sabrina; Downs, David; Monahan, Christine H; Yondorf, Barbara

2013-02-01

Value-based insurance is a relatively new approach to health insurance in which financial barriers, such as copayments, are lowered for clinical services that are considered high value, while consumer cost sharing may be increased for services considered to be of uncertain value. Such plans are complex and do not easily fit into the simplified, consumer-friendly comparison tools that many state health insurance exchanges are formulating for use in 2014. Nevertheless some states and plans are attempting to strike the right balance between a streamlined health exchange shopping experience and innovative, albeit complex, benefit design that promotes value. For example, agencies administering exchanges in Vermont and Oregon are contemplating offering value-based insurance plans as an option in addition to a set of standardized plans. In the postreform environment, policy makers must find ways to present complex value-based insurance plans in a way that consumers and employers can more readily understand.

"Invito alla Vita" is a community-based suicide prevention project that officially started in Trentino in late 2008. The project was promoted by the local Health Services, trying from the beginning to involve other community subjects, and has been working over five years and a half in different directions, particularly promoting a phone help-line. The aims of the Invito alla Vita (IaV) Help Line have been clear from the beginning: decrease the sense of loneliness, offer encouragement and support, promote engagement with health services, reduce stigma and prejudice. Contrary to popular misconceptions, talking with people about suicide will not increase suicide risk, neither will it induce patients to commit suicide.The volunteers involved in the IaV help-line offer people empathic listening without judgment and easy tips, to reduce loneliness, sadness and supply reassurance that other people care. In this study we tried to deepen our knowledges about the volunteers' motivations and necessities to use them for creating a better system of support: we realized indeed that continuous training and supervision, along with official awards given by community institutions, are basic factors to sustain the volunteers' motives to cooperate with the help line.

There are numerous barriers that limit access to evidence-based treatment for posttraumatic stress disorder (PTSD). Internet-based guided self-help is a treatment option that may help widen access to effective intervention, but the approach has not been sufficiently explored for the treatment of PTSD. Forty two adults with DSM-5 PTSD of mild to moderate severity were randomly allocated to internet-based self-help with up to 3 h of therapist assistance, or to a delayed treatment control group. The internet-based program included eight modules that focused on psychoeducation, grounding, relaxation, behavioural activation, real-life and imaginal exposure, cognitive therapy, and relapse prevention. The primary outcome measure was reduction in clinician-rated traumatic stress symptoms using the clinician administered PTSD scale for DSM-V (CAPS-5). Secondary outcomes were self-reported PTSD symptoms, depression, anxiety, alcohol use, perceived social support, and functional impairment. Posttreatment, the internet-based guided self-help group had significantly lower clinician assessed PTSD symptoms than the delayed treatment control group (between-group effect size Cohen's d = 1.86). The difference was maintained at 1-month follow-up and dissipated once both groups had received treatment. Similar patterns of difference between the two groups were found for depression, anxiety, and functional impairment. The average contact with treating clinicians was 2½ h. Internet-based trauma-focused guided self-help for PTSD is a promising treatment option that requires far less therapist time than current first line face-to-face psychological therapy. © 2017 Wiley Periodicals, Inc.

A Rule-Based Data Transfer Protocol for On-Demand Data Exchange in Vehicular Environment

2009-01-01

Full Text Available The purpose of Intelligent Transport System (ITS is mainly to increase the driving safety and efficiency. Data exchange is an important way to achieve the purpose. An on-demand data exchange is especially useful to assist a driver avoiding some emergent events. In order to handle the data exchange under dynamic situations, a rule-based data transfer protocol is proposed in this paper. A set of rules is designed according to the principle of request-forward-reply (RFR. That is, they are used to determine the timing of data broadcasting, forwarding, and replying automatically. Two typical situations are used to demonstrate the operation of rules. One is the front view of a driver occluded by other vehicles. The other is the traffic jam. The proposed protocol is flexible and extensible for unforeseen situations. Three simulation tools were also implemented to demonstrate the feasibility of the protocol and measure the network transmission under high density of vehicles. The simulation results show that the rule-based protocol is efficient on data exchange to increase the driving safety.

Highlights: • The effect of using nano-silver on a commercial plate heat exchanger was studied. • An experimental rig was designed to investigate the thermo-hydrodynamic features of nanofluid. • The overall heat transfer coefficient becomes larger 16.79% for 100 ppm nanofluid. • No significant growth in pressure drop values was observed. • The process temperatures have important role in nanofluid influence. - Abstract: The purpose of this study is to verify the potential using of nano-silver dispersed water based nanofluid on efficiency improvement of a commercial corrugated plate heat exchanger. In this regards, an experimental rig was provided to recognize the heat transfer rate and pressure drop of Ag–water nanofluid as the working fluid. The two most key thermo-physical properties, i.e. dynamic viscosity and thermal conductivity of nanofluids were experimentally gauged. The findings, which were achieved, displayed that the overall heat transfer coefficient becomes larger, from 6.18% to 16.79%, for 100 ppm silver nanofluid. While using nanofluid, no significant growth in pressure drop values was observed. Moreover, the process temperatures and flow rates have significant impacts on the helpfulness of applying nanofluid in a plate heat exchanger.

All knowledge is context dependent. The relevant context is the social community where it resides, i.e. the `epistemic community' formed as groups of people define and legitimize the knowledge they possess. In the mutual engagement in a common enterprise, epistemic communities develop, maintain...... and nurture the codes, tools and theories that provide the basis of their practice. Commonalities of code, tools and theory facilitate both voluntary transfer and involuntary imitation of knowledge within communities, also ones spanning organizational boundaries. Conversely, knowledge transfer between...... different epistemic communities, whether desired or unintended, is often cumbersome and fraught with difficulties. In order to achieve effective integration and cooperation between its various professional communities and subcultures, firms must therefore undertake investments in boundary...

Valuing Our Communities: Ethical Considerations for Economic Evaluation of Community-Based Prevention.

Science.gov (United States)

Crowley, Max; Jones, Damon

2017-12-01

Restricted public budgets and increasing efforts to link the impact of community interventions to public savings have increased the use of economic evaluation. While this type of evaluation can be important for program planning, it also raises important ethical issues about how we value the time of local stakeholders who support community interventions. In particular, researchers navigate issues of scientific accuracy, institutional inequality, and research utility in their pursuit of even basic cost estimates. We provide an example of how we confronted these issues when estimating the costs of a large-scale community-based intervention. Principles for valuing community members' time and conducting economic evaluations of community programs are discussed. © Society for Community Research and Action 2017.

Full Text Available Abstract Community-based organizations are important health system stakeholders as they provide numerous, often highly valued programs and services to the members of their community. However, community-based organizations are described using diverse terminology and concepts from across a range of disciplines. To better understand the literature related to community-based organizations in the health sector (i.e., those working in health systems or more broadly to address population or public health issues, we conducted a scoping review by using an iterative process to identify existing literature, conceptually map it, and identify gaps and areas for future inquiry. We searched 18 databases and conducted citation searches using 15 articles to identify relevant literature. All search results were reviewed in duplicate and were included if they addressed the key characteristics of community-based organizations or networks of community-based organizations. We then coded all included articles based on the country focus, type of literature, source of literature, academic discipline, disease sector, terminology used to describe organizations and topics discussed. We identified 186 articles addressing topics related to the key characteristics of community-based organizations and/or networks of community-based organizations. The literature is largely focused on high-income countries and on mental health and addictions, HIV/AIDS or general/unspecified populations. A large number of different terms have been used in the literature to describe community-based organizations and the literature addresses a range of topics about them (mandate, structure, revenue sources and type and skills or skill mix of staff, the involvement of community members in organizations, how organizations contribute to community organizing and development and how they function in networks with each other and with government (e.g., in policy networks.

Moving beyond non-engagement on regulated needle-syringe exchange programs in Australian prisons

Directory of Open Access Journals (Sweden)

Levy Michael

2009-05-01

Full Text Available Abstract Background Australia is at a fork in the road with the possibility of a needle-syringe exchange program (NSP to be introduced at the new prison in the ACT. However, the current situation is characterised by non-engagement from major stakeholders. We explore why informed discussion will not be enough to convince prison officers, policy makers and the wider community of the benefits of prison-based NSPs. Other methods of engagement and communication will be proposed – in that may provide avenues for "breakthrough". Methods A review of the literature on needle-syringe exchanges and harm reduction strategies within the context of prisons and prisoner health was conducted. Literature on strategies to change attitudes and move beyond intractable situations was also consulted. In addition, one author, DM, conducted a two-hour interview with an ex-prison officer. Results No studies were found which investigated the potential efficacy of interventions to modify attitudes or behaviours in the specific context of introducing an NSP into a prison. Nonetheless, several theories were identified which may explain the failure of informed discussion alone to create change in this situation and may therefore lead to suggestions for engagement and communication to move towards a resolution Discussion Cognitive-behavioural therapy highlights the importance of individual cognitions and how they shape behaviours in any change campaign. Social identity theory emphasizes changes to social processes that may open the prison officer workforce to change. Peace studies also suggests socialization strategies such as observing an established and effective prison-based needle-syringe exchange. Social marketing provides suggestions on how to sell an exchange to ensuring the benefits are framed to outweigh the costs. Conclusion Psychology, peace studies and social marketing all agree people's views must be carefully collected and analysed if people are going to be

Diclofenac removal in urine using strong-base anion exchange polymer resins.

Landry, Kelly A; Boyer, Treavor H

2013-11-01

One of the major sources of pharmaceuticals in the environment is wastewater effluent of which human urine contributes the majority of pharmaceuticals. Urine source separation has the potential to isolate pharmaceuticals at a higher concentration for efficient removal as well as produce a nutrient byproduct. This research investigated the efficacy of using strong-base anion exchange polymer resins to remove the widely detected and abundant pharmaceutical, diclofenac, from synthetic human urine under fresh and ureolyzed conditions. The majority of experiments were conducted using a strong-base, macroporous, polystyrene resin (Purolite A520E). Ion-exchange followed a two-step removal rate with rapid removal in 1 h and equilibrium removal in 24 h. Diclofenac removal was >90% at a resin dose of 8 mL/L in both fresh and ureolyzed urine. Sorption of diclofenac onto A520E resin was concurrent with desorption of an equivalent amount of chloride, which indicates the ion-exchange mechanism is occurring. The presence of competing ions such as phosphate and citrate did not significantly impact diclofenac removal. Comparisons of three polystyrene resins (A520E, Dowex 22, Dowex Marathon 11) as well as one polyacrylic resin (IRA958) were conducted to determine the major interactions between anion exchange resin and diclofenac. The results showed that polystyrene resins provide the highest level of diclofenac removal due to electrostatic interactions between quaternary ammonium functional groups of resin and carboxylic acid of diclofenac and non-electrostatic interactions between resin matrix and benzene rings of diclofenac. Diclofenac was effectively desorbed from A520E resin using a regeneration solution that contained 4.5% (m/m) NaCl in an equal-volume mixture of methanol and water. The greater regeneration efficiency of the NaCl/methanol-water mixture over the aqueous NaCl solution supports the importance of non-electrostatic interactions between resin matrix and benzene rings

Developing a community-based flood resilience measurement standard

2015-04-01

Given the increased attention to resilience-strengthening in international humanitarian and development work, there has been concurrent interest in its measurement and the overall accountability of "resilience strengthening" initiatives. The literature is reaching beyond the polemic of defining resilience to its measurement. Similarly, donors are increasingly expecting organizations to go beyond claiming resilience programing to measuring and showing it. However, key questions must be asked, in particular "Resilience of whom and to what?". There is no one-size-fits-all solution. The approach to measuring resilience is dependent on the audience and the purpose of the measurement exercise. Deriving a resilience measurement system needs to be based on the question it seeks to answer and needs to be specific. This session highlights key lessons from the Zurich Flood Resilience Alliance approach to develop a flood resilience measurement standard to measure and assess the impact of community based flood resilience interventions, and to inform decision-making to enhance the effectiveness of these interventions. We draw on experience in methodology development to-date, together with lessons from application in two case study sites in Latin America. Attention will be given to the use of a consistent measurement methodology for community resilience to floods over time and place; challenges to measuring a complex and dynamic phenomenon such as community resilience; methodological implications of measuring community resilience versus impact on and contribution to this goal; and using measurement and tools such as cost-benefit analysis to prioritize and inform strategic decision making for resilience interventions. The measurement tool follows the five categories of the Sustainable Livelihoods Framework and the 4Rs of complex adaptive systems - robustness, rapidity, redundancy and resourcefulness -5C-4R. A recent white paper by the Zurich Flood Resilience Alliance traces the

There is a recognised need for targeted community-wide mental health strategies and interventions aimed specifically at prevention and early intervention in promoting mental health. Young males are a high need group who hold particularly negative attitudes towards mental health services, and these views are detrimental for early intervention and help-seeking. Organised sports provide a promising context to deliver community-wide mental health strategies and interventions to adolescent males. The aim of the Ahead of the Game program is to test the effectiveness of a multi-component, community-sport based program targeting prevention, promotion and early intervention for mental health among adolescent males. The Ahead of the Game program will be implemented within a sample drawn from community sporting clubs and evaluated using a sample drawn from a matched control community. Four programs are proposed, including two targeting adolescents, one for parents, and one for sports coaches. One adolescent program aims to increase mental health literacy, intentions to seek and/or provide help for mental health, and to decrease stigmatising attitudes. The second adolescent program aims to increase resilience. The goal of the parent program is to increase parental mental health literacy and confidence to provide help. The coach program is intended to increase coaches' supportive behaviours (e.g., autonomy supportive behaviours), and in turn facilitate high-quality motivation and wellbeing among adolescents. Programs will be complemented by a messaging campaign aimed at adolescents to enhance mental health literacy. The effects of the program on adolescent males' psychological distress and wellbeing will also be explored. Organised sports represent a potentially engaging avenue to promote mental health and prevent the onset of mental health problems among adolescent males.

A comparative study of the physicochemical and service properties of samples of Ti(OH) 1.36(HPO4) 1.32 * 2.3H2O sorbent in the finely dispersed and granulated forms, mastered for commercial production, was made. The sorption of Cs and Sr cations from solutions of various, compositions was studied in batch experiments, and the diffusion coefficients of the exchanging ions were determined. The hydrolytic stability of the. sorbents was examined with the aim to determine the optimal operation conditions. Experiments showed that the cation exchangers based on titanium phosphate are the most efficient in removal from liquid radioactive waste of induced radioactive isotopes of corrosion products, which is due to formation of weakly dissociating compounds of nonferrous metal ions with functional groups of the ion exchangers in the sorbent phase.

Large-scale clinical trials and translational studies have demonstrated that weight loss achieved through diet and physical activity reduced the development of diabetes in overweight individuals with prediabetes. These interventions also reduced the occurrence of metabolic syndrome and risk factors linked to other chronic conditions including obesity-driven cancers and cardiovascular disease. The Healthy Living Partnerships to Prevent Diabetes (HELP PD) was a clinical trial in which participants were randomized to receive a community-based lifestyle intervention translated from the Diabetes Prevention Program (DPP) or an enhanced usual care condition. The objective of this study is to compare the 12 and 24 month prevalence of metabolic syndrome in the two treatment arms of HELP PD. The intervention involved a group-based, behavioral weight-loss program led by community health workers monitored by personnel from a local diabetes education program. The enhanced usual care condition included dietary counseling and written materials. HELP PD included 301 overweight or obese participants (BMI 25-39.9kg/m 2 ) with elevated fasting glucose levels (95-125mg/dl). At 12 and 24 months of follow-up there were significant improvements in individual components of the metabolic syndrome: fasting blood glucose, waist circumference, HDL, triglycerides and blood pressure and the occurrence of the metabolic syndrome in the intervention group compared to the usual care group. This study demonstrates that a community diabetes prevention program in participants with prediabetes results in metabolic benefits and a reduction in the occurrence of the metabolic syndrome in the intervention group compared to the enhanced usual care group.

2015-10-01

In the paper, we research on the characteristics of RMB exchange rate time series fluctuation with methods of symbolization and coarse gaining. First, based on fluctuation features of RMB exchange rate, we define the first type of fluctuation mode as one specific foreign currency against RMB in four days' fluctuating situations, and the second type as four different foreign currencies against RMB in one day's fluctuating situation. With the transforming method, we construct the unique-currency and multi-currency complex networks. Further, through analyzing the topological features including out-degree, betweenness centrality and clustering coefficient of fluctuation-mode complex networks, we find that the out-degree distribution of both types of fluctuation mode basically follows power-law distributions with exponents between 1 and 2. The further analysis reveals that the out-degree and the clustering coefficient generally obey the approximated negative correlation. With this result, we confirm previous observations showing that the RMB exchange rate exhibits a characteristic of long-range memory. Finally, we analyze the most probable transmission route of fluctuation modes, and provide probability prediction matrix. The transmission route for RMB exchange rate fluctuation modes exhibits the characteristics of partially closed loop, repeat and reversibility, which lays a solid foundation for predicting RMB exchange rate fluctuation patterns with large volume of data.

In this study, a versatile monomer, vinylbenzyl chloride (VBC) was radiolytically grafted onto a partially fluorinated ETFE and perfluorinated polymer PFA films. The VBC grafted films were treated with trimethylamine to prepare the alkaline anion exchange membranes (AAEMs). No significant differences in the ion exchange capacities and water uptakes were observed between the ETFE and PFA based AAEMs with similar degree of grafting (DOG). However, the distribution patterns of the graft chains over the cross-section of the ETFE and PFA based AAEMs were found to be quite different; the even distribution was observed from the ETFE based AAEMs while the uneven distribution was observed from the PFA based AAEMs. It was also found that the PFA based AAEMs have the higher ionic conductivity and chemical stability, compared to the ETFE based AAEMs.

After a given period of deuteration, the exchange reaction is quenched by acidification (pH 2.5) and cooling (0 °C) and the deuterated protein (or a digest thereof) is analyzed by mass spectrometry. The unavoidable loss of deuterium (back-exchange) that occurs under quench conditions is undesired...... as it leads to loss of information. Here we describe the successful application of a chip-based nanoelectrospray ionization mass spectrometry top-down fragmentation approach based on cooling to subzero temperature (-15 °C) which reduces the back-exchange at quench conditions to very low levels.

Rocket Based Combined Cycle Exchange Inlet Performance Estimation at Supersonic Speeds

Science.gov (United States)

Murzionak, Aliaksandr

A method to estimate the performance of an exchange inlet for a Rocket Based Combined Cycle engine is developed. This method is to be used for exchange inlet geometry optimization and as such should be able to predict properties that can be used in the design process within a reasonable amount of time to allow multiple configurations to be evaluated. The method is based on a curve fit of the shocks developed around the major components of the inlet using solutions for shocks around sharp cones and 2D estimations of the shocks around wedges with blunt leading edges. The total pressure drop across the estimated shocks as well as the mass flow rate through the exchange inlet are calculated. The estimations for a selected range of free-stream Mach numbers between 1.1 and 7 are compared against numerical finite volume method simulations which were performed using available commercial software (Ansys-CFX). The total pressure difference between the two methods is within 10% for the tested Mach numbers of 5 and below, while for the Mach 7 test case the difference is 30%. The mass flow rate on average differs by less than 5% for all tested cases with the maximum difference not exceeding 10%. The estimation method takes less than 3 seconds on 3.0 GHz single core processor to complete the calculations for a single flight condition as oppose to over 5 days on 8 cores at 2.4 GHz system while using 3D finite volume method simulation with 1.5 million elements mesh. This makes the estimation method suitable for the use with exchange inlet geometry optimization algorithm.

Self-help conferences for people who stutter: a qualitative investigation.

Trichon, Mitchell; Tetnowski, John

2011-12-01

Self-help activities for people who stutter (PWS) have been gaining in popularity; however, there is a scarcity of evidence to support their utility in stuttering management. The purpose of this investigation was to understand the lived experience of individuals who attended a self-help conference(s) for PWS from the perspective of a PWS to learn its potential utility in stuttering management. The investigator used Interpretive Phenomenological Analysis (IPA) to systematically collect authentic data of this social phenomenon. Twelve participants were recruited from a self-help conference and the self-help community of PWS. Semi-structured interviews were conducted 4-18 months after each participant's last conference. Interviews were transcribed and analyzed. Themes were explained in investigator narratives and illustrated through participants' quotes. Interpreted themes of the experience of having attended a self-help conference(s) for PWS included: socializing opportunities with other PWS, affiliation, redefining oneself and post-conference disclosures. A conclusion of the study was that the experience of having attended a self-help conference(s) for PWS helped to minimize negative impact that stuttering can have on daily functioning. It appears that self-help conferences were perceived as a safer or "stutter-friendly" environment and promoted social interaction, relationship building, and community building through planned and unplanned activities. Another conclusion was that the experience of having attended self-help conferences for PWS helped participants to communicate more easily. Reported increases in social activity and an "openness" about stuttering, suggest self-help conferences' utility in stuttering management. These findings are supported by other studies about successful stuttering management and self-help activities for PWS. They have helped attendees who stutter to communicate more easily and suggest a reduction in the negative impact that

Key exchange using biometric identity based encryption for sharing encrypted data in cloud environment

The main problem associated with using symmetric/ asymmetric keys is how to securely store and exchange the keys between the parties over open networks particularly in the open environment such as cloud computing. Public Key Infrastructure (PKI) have been providing a practical solution for session key exchange for loads of web services. The key limitation of PKI solution is not only the need for a trusted third partly (e.g. certificate authority) but also the absent link between data owner and the encryption keys. The latter is arguably more important where accessing data needs to be linked with identify of the owner. Currently available key exchange protocols depend on using trusted couriers or secure channels, which can be subject to man-in-the-middle attack and various other attacks. This paper proposes a new protocol for Key Exchange using Biometric Identity Based Encryption (KE-BIBE) that enables parties to securely exchange cryptographic keys even an adversary is monitoring the communication channel between the parties. The proposed protocol combines biometrics with IBE in order to provide a secure way to access symmetric keys based on the identity of the users in unsecure environment. In the KE-BIOBE protocol, the message is first encrypted by the data owner using a traditional symmetric key before migrating it to a cloud storage. The symmetric key is then encrypted using public biometrics of the users selected by data owner to decrypt the message based on Fuzzy Identity-Based Encryption. Only the selected users will be able to decrypt the message by providing a fresh sample of their biometric data. The paper argues that the proposed solution eliminates the needs for a key distribution centre in traditional cryptography. It will also give data owner the power of finegrained sharing of encrypted data by control who can access their data.

2010-01-01

A qualitative study using a phenomenological approach, to explore stroke survivors' needs and their perceptions of whether a community stroke scheme met these needs. Semi-structured in-depth interviews of 12 stroke survivors, purposively selected from participants attending a new community stroke scheme. Interpretative phenomenological analysis of interviews by two researchers independently. Participants attending the community stroke scheme sought to reconstruct their lives in the aftermath of their stroke. To enable this they needed internal resources of confidence and sense of purpose to 'create their social self', and external resources of 'responsive services' and an 'informal support network', to provide direction and encouragement. Participants felt the community stroke scheme met some of these needs through exercise, goal setting and peer group interaction, which included social support and knowledge acquisition. Stroke survivors need a variety of internal and external resources so that they can rebuild their lives positively post stroke. A stroke-specific community scheme, based on exercise, life-centred goal setting, peer support and knowledge acquisition, is an external resource that can help with meeting some of the stroke survivor's needs.

Despite similar prevalence rates across ethnicities, ethnic minorities with obsessive-compulsive disorder (OCD) are under-represented in research and clinical settings. The reasons for this disproportion have been sparsely studied. We explored potential differences in illness perception, help-seeking attitudes, illness knowledge, and causal attributions that could help explain the lower uptake of treatment for OCD amongst ethnic minorities. Two-hundred and ninety-three parents (139 White British, 61 Black African, 46 Black Caribbean, and 47 Indian) were recruited from the general population in South-East London, UK. Using a text vignette methodology, participants completed a survey including questions on illness perception, help-seeking attitudes, OCD knowledge, and causal attributions. The groups did not differ in socio-demographic characteristics and family history of OCD. White British parents perceived that the OCD difficulties would have more negative impact on their children and that treatment would be more helpful, compared to the ethnic minorities; the largest differences were observed between White British and Indian parents. Ethnic minorities were more prone to say that would seek help from their religious communities. Black African parents were more in favor of not seeking help for the described difficulties and, in general, perceived more treatment barriers. White British parents seemed to be better informed about OCD than ethnic minority parents. The results offer some plausible explanations for the large inequalities in access to services amongst ethnic minorities with OCD. Clinicians and policy-makers need to be aware of these socio-cultural factors when designing strategies to encourage help-seeking behaviors in these populations.

Why (and how) to regulate power exchanges in the EU market integration context?

International Nuclear Information System (INIS)

Meeus, Leonardo

2011-01-01

The European Union (EU) market integration is leading to increasingly monopolistic electricity market infrastructures, which has opened a debate on the regulation of these so-called power exchanges. In this paper, we start by stating that there are two types of power exchanges in Europe, i.e. 'merchant' and 'cost-of-service regulated' power exchanges. We then discuss how regulation can be used to better align their incentives with the main power exchange tasks. We conclude that adopting the cost-of-service regulated model for all power exchanges in Europe could be counterproductive in the current context, but that regulation can help ensure that the benefits of the EU market integration materialize. Promising regulatory actions include tempering the reinforced market power of power exchanges, and quality-of-service regulation for the ongoing cooperation among power exchanges to organize trade across borders. - Research highlights: → Market integration is leading to increasingly monopolistic electricity market infrastructures. → Regulation can help tempering the market power of these so-called power exchanges in Europe. → Cost-of-service regulation for all power exchanges could however be counterproductive. → More promising is to subject cooperation among power exchanges to quality of service regulation.

In 2010, the Brooklyn Active Transportation Community Planning Initiative launched in 2 New York City neighborhoods. Over a 2-year planning period, residents participated in surveys, school and community forums, neighborhood street assessments, and activation events-activities that highlighted the need for safer streets locally. Consensus among residents and key multisectoral stakeholders, including city agencies and community-based organizations, was garnered in support of a planned expansion of bicycling infrastructure. The process of building on community assets and applying a collective impact approach yielded changes in the built environment, attracted new partners and resources, and helped to restore a sense of power among residents.

Geo3DML: A standard-based exchange format for 3D geological models

Wang, Zhangang; Qu, Honggang; Wu, Zixing; Wang, Xianghong

2018-01-01

A geological model (geomodel) in three-dimensional (3D) space is a digital representation of the Earth's subsurface, recognized by geologists and stored in resultant geological data (geodata). The increasing demand for data management and interoperable applications of geomodelscan be addressed by developing standard-based exchange formats for the representation of not only a single geological object, but also holistic geomodels. However, current standards such as GeoSciML cannot incorporate all the geomodel-related information. This paper presents Geo3DML for the exchange of 3D geomodels based on the existing Open Geospatial Consortium (OGC) standards. Geo3DML is based on a unified and formal representation of structural models, attribute models and hierarchical structures of interpreted resultant geodata in different dimensional views, including drills, cross-sections/geomaps and 3D models, which is compatible with the conceptual model of GeoSciML. Geo3DML aims to encode all geomodel-related information integrally in one framework, including the semantic and geometric information of geoobjects and their relationships, as well as visual information. At present, Geo3DML and some supporting tools have been released as a data-exchange standard by the China Geological Survey (CGS).

The purpose of this mixed-methods study was to gain insight about Native Hawaiian (NH) women's experiences with, and viewpoints of, depression and help-seeking behaviors (N = 30: 10 from the university and 20 from the community). More women reported depression in the interviews than through their Center for Epidemiologic Studies Depression Scale (CES-D) responses. Quantitative data revealed 57% of the women had ever received mental health help (80% of university vs. 45% of community sample). There was a range of satisfaction reported for various types of mental health care, with satisfaction being the highest for spiritual/religious advisor/folk healer. During the interviews, one woman reported that she is currently receiving professional care and five women are seeking help from their family/social network. Future research should explore reasons for the differences in the quantitative and qualitative findings regarding depression and associated help-seeking as well as in the satisfaction levels by type of help-seeking.

Full Text Available The high volatility combined with unpredictable fluctuations of CZK had shown one more time to the Czech exporting companies the necessity of currency hedging. This article is focused on finding of suitable currency hedging instrument for exporting company, working with the currency pair of CZK/EUR. In the first part, the time series analysis is made for volatility, interest rates and exchange rate. Based on the real market data – gained from Thomson REUTERS and CNB for the time period starting in 2002 – the detailed analysis is made in graphical form. The main goal is to find out the future trends with help of liner regression analysis, based on the historical data. Several graphs are provided with the trend line end estimated interval (min and max for the each variable. The calculated values are clearly marked, to be separated from the real market data. Exchange rate curve shows the market behaviour in the last years and is to be used as most important indicator for the future trends. Interest rates curves are very important for the calculation of the BIPS (basis points, determining the price of the forwards. The difference between landing and deposit rates for the same period of time and different currencies are showing the market estimation of the future development of each currency. Forward price is to be seen as a benchmark for the all other financial instruments.

The Merck Childhood Asthma Network (MCAN) initiative selected five sites (New York City, Puerto Rico, Chicago, Los Angeles, and Philadelphia) to engage in translational research to adapt evidence-based interventions (EBIs) to improve childhood asthma outcomes. The authors summarize the sites' experience by describing criteria defining the fidelity of translation, community contextual factors serving as barriers or enablers to fidelity, types of adaptation conducted, and strategies used to balance contextual factors and fidelity in developing a "best fit" for EBIs in the community. A conceptual model captures important structural and process-related factors and helps frame lessons learned. Site implementers and intervention developers reached consensus on qualitative rankings of the levels of fidelity of implementation for each of the EBI core components: low fidelity, adaptation (major vs. minor), or high fidelity. MCAN sites were successful in adapting core EBI components based on their understanding of structural and other contextual barriers and enhancers in their communities. Although the sites varied regarding both the EBI components they implemented and their respective levels of fidelity, all sites observed improvement in asthma outcomes. Our collective experiences of adapting and implementing asthma EBIs highlight many of the factors affecting translation of evidenced-based approaches to chronic disease management in real community settings.

Full Text Available Accumulating foreign exchange reserves, despite their cost and their impacts on other macroeconomics variables, provides some benefits. This paper models such foreign exchange reserves. To measure the adequacy of foreign exchange reserves for import, it uses total reserves-to-import ratio (TRM. The chosen independent variables are gross domestic product growth, exchange rates, opportunity cost, and a dummy variable separating the pre and post 1997 Asian financial crisis. To estimate the risky TRM value, this paper uses conditional Value-at-Risk (VaR, with the help of Glosten-Jagannathan-Runkle (GJR model to estimate the conditional volatility. The results suggest that all independent variables significantly influence TRM. They also suggest that the short and long run volatilities are evident, with the additional evidence of asymmetric effects of negative and positive past shocks. The VaR, which are calculated assuming both normal and t distributions, provide similar results, namely violations in 2005 and 2008.

Full Text Available We review the Symbiota software platform for creating voucher-based biodiversity information portals and communities. Symbiota was originally conceived to promote small- to medium-sized, regionally and/or taxonomically themed collaborations of natural history collections. Over the past eight years the taxonomically diverse portals have grown into an important resource in North America and beyond for mobilizing, integrating, and using specimen- and observation-based occurrence records and derivative biodiversity information products. Designed to mirror the conceptual structure of traditional floras and faunas, Symbiota is exclusively web-based and employs a novel data model, information linking, and algorithms to provide highly dynamic customization. The themed portals enable meaningful access to biodiversity data for anyone from specialist to high school student. Symbiota emulates functionality of modern Content Management Systems, providing highly sophisticated yet intuitive user interfaces for data entry, batch processes, and editing. Each kind of content provision may be selectively accessed by authenticated information providers. Occupying a fairly specific niche in the biodiversity informatics arena, Symbiota provides extensive data exchange facilities and collaborates with other development projects to incorporate and not duplicate functionality as appropriate.

Community-based dental education and the importance of faculty development.

Science.gov (United States)

McAndrew, Maureen

2010-09-01

Community-based dental education offers a variety of positive learning experiences for students while providing needed dental services for the underserved. More dental students are being instructed by a growing body of largely volunteer community-based faculty who practice in a wide range of community settings including community hospitals and clinics, nursing homes, and private practices. These geographically dispersed instructors may have little experience as educators. Their practice styles and their motivation to improve teaching effectiveness are likely to differ from the styles and motivation of school-based faculty members. Moreover, many dental schools have begun to emphasize practices that may be unfamiliar to community-based faculty such as evidence-based practice. Providing faculty development for them is challenging, yet crucial to the success of these programs and dental education in general. Fundamental elements that must be considered for effective community faculty development programming include fostering a culture of respect between school-based and community faculty members, basing programs on the actual needs of these educators, integrating principles of adult learning theory, and establishing ongoing institutional support. This article provides background on this movement, reviews the literature for faculty development programs geared specifically to community-based educators, makes recommendations for development programs for these dental educators, and includes suggestions for future research.

The level of vaccination coverage in a given community depends on both service factors and the degree to which the public understands and trusts the immunization process. This article describes an approach that aims to raise awareness and boost demand. Developed in India, the "My Village Is My Home" (MVMH) tool, known as Uma Imunizasaun (UI) in Timor-Leste, is a poster-sized material used by volunteers and health workers to record the births and vaccination dates of every infant in a community. Introduction of the tool in 5 districts of India (April 2012 to March 2013) and in 7 initial villages in Timor-Leste (beginning in January 2012) allowed community leaders, volunteers, and health workers to monitor the vaccination status of every young child and guided reminder and motivational visits. In 3 districts of India, we analyzed data on vaccination coverage and timeliness before and during use of the tool; in 2 other districts, analysis was based only on data for new births during use of the tool. In Timor-Leste, we compared UI data from the 3 villages with the most complete data with data for the same villages from the vaccination registers from the previous year. In both countries, we also obtained qualitative data about perceptions of the tool through interviews with health workers and community members. Assessments in both countries found evidence suggesting improved vaccination timeliness and coverage. In India, pilot communities had 80% or higher coverage of identified and eligible children for all vaccines. In comparison, overall coverage in the respective districts during the same time period was much lower, at 49% to 69%. In Timor-Leste, both the number of infants identified and immunized rose substantially with use of the tool compared with the previous year (236 vs. 155, respectively, identified as targets; 185 vs. 147, respectively, received Penta 3). Although data challenges limit firm conclusions, the experiences in both countries suggest that "My

This paper presents the results of a review of literature relating to knowledge transfer and exchange in healthcare. Treatment, planning and policy decisions in contemporary nursing and healthcare should be based on sound evidence wherever possible, but research knowledge remains generally underused. Knowledge transfer and exchange initiatives aim to facilitate the accessibility, application and production of evidence and may provide solutions to this challenge. This review was conducted to help inform the design and implementation of knowledge transfer and exchange activities for a large healthcare organization. Databases: ASSIA, Business Source Premier, CINAHL, PsychInfo, Medline and the Cochrane Database of Systematic Reviews. An integrative literature review was carried out including an extensive literature search. English language systematic reviews, literature reviews, primary quantitative and qualitative papers and grey literature of high relevance evaluating, describing or discussing knowledge transfer or exchange activities in healthcare were included for review (January 1990-September 2009). Thirty-three papers were reviewed (four systematic reviews, nine literature reviews, one environmental scan, nine empirical studies and ten case studies). Robust research into knowledge transfer and exchange in healthcare is limited. Analysis of a wide range of evidence indicates a number of commonly featured characteristics but further evaluation of these activities would benefit their application in facilitating evidence-based practice in nursing. © 2011 The Authors.

A collaborative effort of the Catholic Health Association (CHA) and the American Association of Homes for the Aging, The Social Accountability Program: Continuing the Community Benefit Tradition of Not-for-Profit Homes and Services for the Aging helps long-term care organizations plan and report community benefit activities. The program takes long-term care providers through five sequential tasks: reaffirming commitment to the elderly and others in the community; developing a community service plan; developing and providing community services; reporting community services; and evaluating the community service role. To help organizations reaffirm commitment, the Social Accountability Program presents a process facilities can use to review their historical roots and purposes and evaluate whether current policies and procedures are consistent with the organizational philosophy. Once this step is completed, providers can develop a community service plan by identifying target populations and the services they need. For facilities developing and implementing such services, the program suggests ways of measuring and monitoring them for budgetary purposes. Once they have implemented services, not-for-profit healthcare organizations must account for their impact on the community. The Social Accountability Program lists elements to be included in community service reports. It also provides guidelines for evaluating these services' effectiveness and the organization's overall community benefit role.

Background Numerous publications demonstrate the importance of community-based participatory research (CBPR) in community health research, but few target the Deaf community. The Deaf community is understudied and underrepresented in health research despite suspected health disparities and communication barriers. Objectives The goal of this paper is to share the lessons learned from the implementation of CBPR in an understudied community of Deaf American Sign Language (ASL) users in the greater Rochester, New York, area. Methods We review the process of CBPR in a Deaf ASL community and identify the lessons learned. Results Key CBPR lessons include the importance of engaging and educating the community about research, ensuring that research benefits the community, using peer-based recruitment strategies, and sustaining community partnerships. These lessons informed subsequent research activities. Conclusions This report focuses on the use of CBPR principles in a Deaf ASL population; lessons learned can be applied to research with other challenging-to-reach populations. PMID:22982845

Full Text Available The purpose of the paper is to determine threats and benefits of exchange rate regimes in terms of the integration of Ukraine into the European community. Emphasizing features of the manifestation of currency exchange rate in Ukrainian practice is a precondition for choosing the optimal exchange rate regime for Ukraine, which, in its turn, will provide an opportunity to reduce inflation and implement effective tools of monetary and fiscal policies to promote further economic growth and competitiveness of the country. The uses of free-floating exchange rate and «currency board» regimes have either positive effects for Ukraine or certain threats. Methodology. This research is based on a synthesis of data on the uses of exchange rate regimes in Ukraine as an independent. It is considered angular regimes, which are by far the most suitable for Ukraine in terms of the European vector of its development. Peculiarities of using these regimes are revealed and their major threats to the domestic economy are pointed out. This article analyzes the dynamics of the trade balance of payments of Ukraine, the dynamics of the commodity structure of Ukraine`s exports and imports and the external debt of Ukraine. Results. Taking into account the experience of countries, which were in crisis situations, they show the necessity of the uses of freefloating exchange rate regime and possibilities of «currency board» regime, despite threats that they may have. World experience testifies the implementation of structural reforms, effective monetary policy, fiscal policy and discipline of the government. Thorough preparation of Ukraine’s transition to the «currency board» regime can justify itself in conditions of crisis and provide impetus to Ukrainian economy benefits. The paper defines conditions under which the success of a new model of exchange rate policy will be achieved. Practical implications. The study accents attention on the specifics of the uses of the

Evidence on influenza vaccine effectiveness from low and middle countries (LMICs) is limited due to limited institutional capacities; lack of adequate resources; and lack of interest by ministries of health for influenza vaccine introduction. There are concerns that the highest ethical standards will be compromised during trials in LMICs leading to mistrust of clinical trials. These factors pose regulatory and operational challenges to researchers in these countries. We conducted a community-based vaccine trial to assess the efficacy of live attenuated influenza vaccine and inactivated influenza vaccine in rural north India. Key regulatory challenges included obtaining regulatory approvals, reporting of adverse events, and compensating subjects for trial-related injuries; all of which were required to be completed in a timely fashion. Key operational challenges included obtaining audio-visual consent; maintaining a low attrition rate; and administering vaccines during a narrow time period before the influenza season, and under extreme heat. We overcame these challenges through advanced planning, and sustaining community engagement. We adapted the trial procedures to cope with field conditions by conducting mock vaccine camps; and planned for early morning vaccination to mitigate threats to the cold chain. These lessons may help investigators to confront similar challenges in other LMICs.

A trait-based framework for stream algal communities.

2016-01-01

The use of trait-based approaches to detect effects of land use and climate change on terrestrial plant and aquatic phytoplankton communities is increasing, but such a framework is still needed for benthic stream algae. Here we present a conceptual framework of morphological, physiological, behavioural and life-history traits relating to resource acquisition and resistance to disturbance. We tested this approach by assessing the relationships between multiple anthropogenic stressors and algal traits at 43 stream sites. Our "natural experiment" was conducted along gradients of agricultural land-use intensity (0-95% of the catchment in high-producing pasture) and hydrological alteration (0-92% streamflow reduction resulting from water abstraction for irrigation) as well as related physicochemical variables (total nitrogen concentration and deposited fine sediment). Strategic choice of study sites meant that agricultural intensity and hydrological alteration were uncorrelated. We studied the relationships of seven traits (with 23 trait categories) to our environmental predictor variables using general linear models and an information-theoretic model-selection approach. Life form, nitrogen fixation and spore formation were key traits that showed the strongest relationships with environmental stressors. Overall, FI (farming intensity) exerted stronger effects on algal communities than hydrological alteration. The large-bodied, non-attached, filamentous algae that dominated under high farming intensities have limited dispersal abilities but may cope with unfavourable conditions through the formation of spores. Antagonistic interactions between FI and flow reduction were observed for some trait variables, whereas no interactions occurred for nitrogen concentration and fine sediment. Our conceptual framework was well supported by tests of ten specific hypotheses predicting effects of resource supply and disturbance on algal traits. Our study also shows that investigating a

Timely and cost-effective analytics over social network has emerged as a key ingredient for success in many businesses and government endeavors. Community detection is an active research area of relevance to analyze online social network. The problem of selecting a particular community detection algorithm is crucial if the aim is to unveil the community structure of a network. The choice of a given methodology could affect the outcome of the experiments because different algorithms have different advantages and depend on tuning specific parameters. In this paper, we propose a community division model based on the notion of game theory, which can combine advantages of previous algorithms effectively to get a better community classification result. By making experiments on some standard dataset, it verifies that our community detection model based on game theory is valid and better.

1998-01-01

Laboratory tests were performed to examine the efficacy of leach treatments for decontaminating organic ion exchange resins (OIER), which have been found in a number of samples retrieved from K East Basin sludge. Based on process records, the OIER found in the K Basins is a mixed-bet strong acid/strong base material marketed as Purolitetrademark NRW-037. Radionuclides sorbed or associated with the OIER can restrict its disposal to the Environmental Restoration Disposal Facility (ERDF). The need for testing to support development of a treatment process for K Basin sludge has been described in Section 4.2 of ''Testing Strategy to Support the Development of K Basins Sludge Treatment Process'' (Flament 1998). To help understand the effects of anticipated OIER elutriation and washing, tests were performed with well-rinsed OIER material from K East Basin floor sludge (sample H-08 BEAD G) and with well-rinsed OIER having approximately 5% added K East canister composite sludge (sample KECOMP). The rinsed resin-bearing material also contained the inorganic ion exchanger Zeolon-900trademark, a zeolite primarily composed of the mineral mordenite. The zeolite was estimated to comprise 27 weight percent of the dry H-08 BEAD G material

Falling Through the Cracks: How the Community-Based Approach Has Failed Calgary’s Chronically Homeless

Full Text Available The seeds of chronic homelessness, with the addictions and mental illness that often accompany it, are sown frequently in traumatic childhoods. A survey of 300 people experiencing chronic homelessness and those sleeping rough in Calgary reveals that these individuals have suffered childhood trauma at a rate five times higher than the general population. Those traumas include neglect, parents with addiction issues, domestic violence and abuse. Unfortunately for those seeking help, community-based services in Calgary have been unable to keep up since the prevailing philosophy became one of releasing these people from institutions into the community. A 62 per cent reduction in psychiatric beds some 30 years ago was accompanied by levels of funding that simply weren’t enough to provide all the resulting community services needed. People without families to turn to, and with no social supports, tended to end up homeless. It has become a vicious circle – while mental health issues can lead to homelessness, homelessness also puts people at greater risk for mental illness. Because childhood trauma plays such a key role in chronic homelessness, it needs to be figured into the kinds of housing and support programs that are put in place for people who are homeless. Psychiatric supports should be among the programs that homeless shelters offer and should also be provided on a priority basis for people using the intervention program called Housing First. There is no doubt about the link between adverse childhood experiences and future mental health problems. People who have experienced at least four types of childhood trauma are 12 times more likely to have attempted suicide, seven times more likely to be alcoholic, and 10 times more likely to have injected street drugs. They are also much more likely to be violent. Interaction with the health-care and justice systems started early for the individuals surveyed in Calgary, aged between 18 and 80. Forty

High Temperature Gas-to-Gas Heat Exchanger Based on a Solid Intermediate Medium

Directory of Open Access Journals (Sweden)

R. Amirante

2014-04-01

Full Text Available This paper proposes the design of an innovative high temperature gas-to-gas heat exchanger based on solid particles as intermediate medium, with application in medium and large scale externally fired combined power plants fed by alternative and dirty fuels, such as biomass and coal. An optimization procedure, performed by means of a genetic algorithm combined with computational fluid dynamics (CFD analysis, is employed for the design of the heat exchanger: the goal is the minimization of its size for an assigned heat exchanger efficiency. Two cases, corresponding to efficiencies equal to 80% and 90%, are considered. The scientific and technical difficulties for the realization of the heat exchanger are also faced up; in particular, this work focuses on the development both of a pressurization device, which is needed to move the solid particles within the heat exchanger, and of a pneumatic conveyor, which is required to deliver back the particles from the bottom to the top of the plant in order to realize a continuous operation mode. An analytical approach and a thorough experimental campaign are proposed to analyze the proposed systems and to evaluate the associated energy losses.

Development of community plans to enhance survivorship from colorectal cancer: community-based participatory research in rural communities.

In 2002, 10.4% of the 10 million persons alive who have ever been diagnosed with cancer had colorectal cancer (CRC). Barriers, such as distance, terrain, access to care and cultural differences, to CRC survivorship may be especially relevant in rural communities. We tested the hypothesis that teams from rural cancer coalitions and hospitals would develop a Community Plan (CP) to enhance CRC survivorship. We used community-based participatory research and the PRECEDE-PROCEED model to train teams from rural cancer coalitions and hospitals in Pennsylvania and New York. We measured knowledge at three points in time and tested the change with McNemar's test, corrected for multiple comparisons (p < 0.0167). We also conducted a qualitative review of the CP contents. Fourteen (93.3%) of the 15 coalitions or hospitals initially recruited to the study completed a CP. Knowledge in public health, sponsorship of A National Action Plan for Cancer Survivorship, and CRC survivorship and treatment increased. Teams identified perceived barriers and community assets. All teams planned to increase awareness of community assets and almost all planned to enhance treatment-related care and psychosocial care for the CRC survivor; 50% planned to enhance primary care and CRC screening. The study demonstrated the interest and ability of rural organizations to plan to enhance CRC survivorship, including linkage of CRC survivorship to primary care. Rural cancer coalitions and hospitals may be a vehicle to develop local action for A National Action Plan. Access to more comprehensive care for CRC cancer survivors in rural communities appears to be facilitated by the community-based initiative described and investigated in this study. Efforts such as these could be replicated in other rural communities and may impact the care and quality of life of survivors with many types of cancers. While access to health services may be increased through community-based initiatives, we still need to measure

As a clean and highly efficient energy source, the proton exchange membrane fuel cell (PEMFC) has been considered an ideal alternative to traditional fossil energy sources. Great efforts have been devoted to realizing the commercialization of the PEMFC in the past decade. To eliminate some technical problems that are associated with the low-temperature operation (such as catalyst poisoning and poor water management), PEMFCs are usually operated at elevated temperatures (e.g., > 100 degrees C). However, traditional proton exchange membrane (PEM) shows poor performance at elevated temperature. To achieve a high-performance PEM for high temperature fuel cell applications, novel PEMs, which are based on nanostructures, have been developed recently. In this review, we discuss and summarize the methods for fabricating the nanostructure-based PEMs for PEMFC operated at elevated temperatures and the high temperature performance of these PEMs. We also give an outlook on the rational design and development of the nanostructure-based PEMs.

Humanitarian workers in disaster settings report a dramatic increase in gender-based violence (GBV). This was true after the 2010 Haiti earthquake when women and girls lost the relative security of their homes and families. Researchers from the United States Virgin Islands and the United States mainland responded by collaborating with Haitian colleagues to develop GBV-focused strategies. To start, the research team performed a situational analysis to insure that the project was culturally, ethically, and logistically appropriate. The aim of this paper is to describe how the situational analysis framework helped the researchers effectively approach this community. Using post-earthquake Haiti as an exemplar, we identify key steps, barriers, and facilitators to undertaking a situational analysis. Barriers included logistics, infrastructure, language and community factors. Facilitators included established experts, organizations and agencies. Researchers in such circumstances need to be respectful of community members as experts and patient with local environmental and cultural conditions.

Community-based participatory research has been seen to hold great promise by researchers aiming to bridge research and action in global health programs and practice. However, there is still much debate around whether achieving authenticity in terms of in-depth collaboration between community and academic partners is possible while pursuing academic expectations for quality. This article describes the community-based methodology for a qualitative study to explore intimate partner violence and HIV/AIDS among women in sex work, or female sex workers, and their male partners in Karnataka, South India. Developed through collaborative processes, the study methodology followed an interpretive approach to qualitative inquiry, with three key components including long-term partnerships, knowledge exchange, and orientation toward action. We then discuss lessons learned on how to pursue authenticity in terms of truly collaborative processes with inherent value that also contribute to, rather than hinder, the instrumental goal of enhancing the quality and relevance of the research outcomes. © The Author(s) 2016.

Ordinary physico-chemical methods have been used for studying the possibilities of the ion-exchange synthesis of niobates of alkaline and alkaline-earth elements based on low-water niobium hydroxide small at relatively low temperatures. It has been established that cation-exchange properties of low-water niobium hydroxide are revealed in a wide range of pH (from 8.95 to 12.4 for alkaline-earth elements and from 6.7 to 12.0 for alkaline elements). Physico-chemical study of solid phases points that there is a monophase with low-water niobium hydroxide. The rate of crystallization ageing of amorphous phases based on low-water niobium hydroxide is rather small for the samples with a M:Nb ratio less than 1.0 whereas mixed hydroxides with M:Nb ratio more than 1.0 reveal on X-ray diffraction patterns diffusion reflections after keeping in mother liquor for 5 hours-1 day

Rural communities, particularly Aboriginal communities, often have limited access to health information, a situation that can have significant negative consequences. To address the lack of culturally and geographically relevant health information, a community-university partnership was formed to develop, implement, and evaluate Aboriginal Community Learning Centres (CLCs). The objective of this paper is to evaluate the community-based research process used in the development of the CLCs. It focuses on the process of building relationships among partners and the CLC's value and sustainability. Semistructured interviews were conducted with key stakeholders, including principal investigators, community research leads, and supervisors. The interview transcripts were analyzed using an open-coding process to identify themes. Key challenges included enacting shared project governance, negotiating different working styles, and hiring practices based on commitment to project objectives rather than skill set. Technological access provided by the CLCs increased capacity for learning and collective community initiatives, as well as building community leads' skills, knowledge, and self-efficacy. An important lesson was to meet all partners "where they are" in building trusting relationships and adapting research methods to fit the project's context and strengths. Successful results were dependent upon persistence and patience in working through differences, and breaking the project into achievable goals, which collectively contributed to trust and capacity building. The process of building these partnerships resulted in increased capacity of communities to facilitate learning and change initiatives, and the capacity of the university to engage in successful research partnerships with Aboriginal communities in the future.

2018-02-01

This article aimed to review community-based disaster management in terms of its independent coordination and disaster management. Community resilience was tested during disaster emergency. While panic, the community is required to be viable and able to evacuate, manage logistic, collect data on damage and the victim, and coordinate with outsiders independently. The community in Gununglurah Village, Banyumas Regency which was hit by a landslide in 2015 provides a lesson learned about community based disaster management. This research used qualitative descriptive methodology with in-depth interview with 23 informants from the community, donor institution, village officers, and government officers. Through traditional and informal methods, the community implemented disaster management that was categorized into 3 mechanisms that were social, functional, and sequential mechanism. These mechanisms controlled different portion in which social mechanism holds the most important role in disaster management, then functional mechanism and sequential mechanism. Various community activities in the village equipped the community with organizational experience to manage logistic, human resource and other coordination. In 2007, in fact, there was vulnerability risk assessment done by the local government, which recommended efforts to be done by the community to reduce the disaster risk, yet it was not implemented. It was interesting to note that in spite of the independent disaster management there was a scientific assessment neglected. Based on this research, a new discussion on how to synchronize the endogenous knowledge with scientific modern knowledge was opened.

Batterham, Philip J; Calear, Alison L

2017-06-30

Despite extensive evidence that Internet interventions are effective in treating mental health problems, uptake of Internet programs is suboptimal. It may be possible to make Internet interventions more accessible and acceptable through better understanding of community preferences for delivery of online programs. This study aimed to assess community preferences for components, duration, frequency, modality, and setting of Internet interventions for mental health problems. A community-based online sample of 438 Australian adults was recruited using social media advertising and administered an online survey on preferences for delivery of Internet interventions, along with scales assessing potential correlates of these preferences. Participants reported a preference for briefer sessions, although they recognized a trade-off between duration and frequency of delivery. No clear preference for the modality of delivery emerged, although a clear majority preferred tailored programs. Participants preferred to access programs through a computer rather than a mobile device. Although most participants reported that they would seek help for a mental health problem, more participants had a preference for face-to-face sources only than online programs only. Younger, female, and more educated participants were significantly more likely to prefer Internet delivery. Adults in the community have a preference for Internet interventions with short modules that are tailored to individual needs. Individuals who are reluctant to seek face-to-face help may also avoid Internet interventions, suggesting that better implementation of existing Internet programs requires increasing acceptance of Internet interventions and identifying specific subgroups who may be resistant to seeking help. ©Philip J Batterham, Alison L Calear.

Challenges associated with recruiting and retaining community-based populations in research studies have been recognized yet remain of major concern for researchers. There is a need for exchange of recruitment and retention techniques that inform recruitment and retention strategies. Here, the authors discuss a variety of methods that were successful in exceeding target recruitment and retention goals in a randomized clinical trial of hearing protector use among farm operators. Recruitment and retention strategies were 1) based on a philosophy of mutually beneficial engagement in the research process, 2) culturally appropriate, 3) tailored to the unique needs of partnering agencies, and 4) developed and refined in a cyclical and iterative process. Sponsoring organizations are interested in cost-effective recruitment and retention strategies, particularly relating to culturally and ethnically diverse groups. These approaches may result in enhanced subject recruitment and retention, concomitant containment of study costs, and timely accomplishment of study aims. Copyright © 2014 Elsevier Inc.

The European Union (EU) market integration is leading to increasingly monopolistic electricity market infrastructures, which has opened a debate on the regulation of these so-called power exchanges. In this paper, we start by stating that there are two types of power exchanges in Europe, i.e. 'merchant' and 'cost-of-service regulated' power exchanges. We then discuss how regulation can be used to better align their incentives with the main power exchange tasks. We conclude that adopting the cost-of-service regulated model for all power exchanges in Europe could be counterproductive in the current context, but that regulation can help ensure that the benefits of the EU market integration materialize. Promising regulatory actions include tempering the reinforced market power of power exchanges, and quality-of-service regulation for the ongoing cooperation among power exchanges to organize trade across borders. - Research highlights: {yields} Market integration is leading to increasingly monopolistic electricity market infrastructures. {yields} Regulation can help tempering the market power of these so-called power exchanges in Europe. {yields} Cost-of-service regulation for all power exchanges could however be counterproductive. {yields} More promising is to subject cooperation among power exchanges to quality of service regulation.

We aimed to study the development and implementation of promotion of physical activity in a rural community by applying the principles of social marketing and to determine participation behaviour in a physical activity programme in a community setting. The intervention targeted 485 people, 20-49 years of age, residents of Periakattupalayam and Rangareddipalayam villages, Tamil Nadu. This community-based participatory research was based on the principles of 'social marketing'. Health education by one-to-one counselling, written materials and community events were used to popularize moderate intensity physical activity (brisk walking for 30 minutes on 4 days/week). We formed 30 walking groups under four coordinators, in a home-based setting with professional supervision and guidance. A log of physical activity sessions for the 10-week intervention period was maintained in the form of group attendance record. Village leaders, self-help groups and youth clubs were involved in promoting physical activity. Of the 485 subjects, 265 people (54.6%) engaged in brisk walking >4 days a week, while 156 subjects (32.2%) performed walking on 1-4 days per week during the intervention. The drop-out rate was 13.2% (64 subjects). Age, occupation and educational status were important determinants of participation and adherence to the physical activity programme. Application of social marketing techniques in an intervention to promote physical activity was successful in a rural Indian community. Studying the determinants of adoption of a physical activity programme and addressing the barriers to behaviour change are essential for designing relevant policies and effective programmes.

Social Resources and Community Resilience in the Wake of Superstorm Sandy.

Directory of Open Access Journals (Sweden)

Kathleen A Cagney

Full Text Available Recovery efforts after natural disasters typically focus on physical infrastructure. In general less attention is paid to the social infrastructure that might impact the capacity of the community to rebuild. We examine perceptions of preparedness and recovery (markers of resilience at the community level in the wake of Superstorm Sandy with a novel data set that includes a multi-mode survey of twelve neighborhoods severely affected by the storm. With these data, we suggest that social resources are associated with beliefs about neighborhood resilience. People who live in communities with higher social cohesion (coefficient = .73, p <.001, informal social control (coefficient = .53, p <.001, and social exchange (coefficient = .69, p <.001 are more likely to believe their neighborhoods are well prepared for a disaster. Likewise, people living in communities with higher social cohesion (coefficient = .35, p <.01, informal social control (coefficient = .27, p <.05, and social exchange (coefficient = .42, p <.001 are more likely to be confident their neighborhoods will recover quickly from a disaster. However, the effects of social resources on beliefs about resilience vary based on neighborhood socioeconomic status (SES and the impact of the storm. Informal social control and social exchange lead to a greater increase in confidence in recovery in low, as compared to high, SES neighborhoods. Social resources tend to have more impact on perceptions of recovery in communities less affected by the storm. In sum, these findings suggest the potential value of various forms of social intervention to better equip communities to respond when disaster strikes.

Increasing participation in physical activity is a goal for many health care providers working with persons with disability. In order to reduce the physical and social barriers to participation, there is a need to develop approaches that integrate self-help with professional help for autonomous yet supported health promotion. This study reports on an innovative program, entitled the "Blue Prescription approach", in which physical therapists work collaboratively with persons with a disability to promote community-based physical activity participation. We trialed this collaborative approach with two physical therapists and 27 participants with multiple sclerosis (MS) over a three month period. We gathered qualitative data from four sources: (i) individual interviews with our participants, (ii) individual interviews with the physical therapists, (iii) clinical notes, and (iv) Advisory Group meeting notes. We then analyzed these data for categories to inform the content and resources required for delivery of the approach. For most participants, the Blue Prescription approach facilitated regular engagement in the physical activity of their choice. The Advisory Group provided advice to help solve individual contexts that presented as challenges to participants. Based on review of interview transcripts, we identified four strategies or issues to inform the further development of Blue Prescription. Evidence indicated that the Blue Prescription approach can provide a collaborative and flexible way for physical therapists to work with individuals with MS, to increase participation in community-based physical activity. To further develop the approach, there is a need to address issues related to the use of standardized measures and develop strategies to train physical therapists in collaborative approaches for promotion of physical activity.The integration of self-help and professional help provided by the Blue Prescription approach appeared to result in successful promotion

Actively engaging communities in effective partnerships is considered critical for ethically robust and locally relevant HIV prevention research. This can be challenging in developing countries that have little prior experience in this area. This paper summarizes processes and lessons learnt while setting up the Community Involvement Plan of National AIDS Research Institute, Pune, India. Formal partnerships were established with voluntary agencies. The focus was on using strategies adapted from participatory learning and action techniques. The community program was implemented through peer educators specifically identified from the communities where partner non-governmental organizations function. At the grass root level, peer educators imparted education to the common people about research studies and helped to implement community based recruitment and retention activities. The focus was on facilitating periodic interaction between the outreach workers of the research team and the peers and modifying the strategies till they were found locally implementable and appropriate. Through adequate time investment, mutually beneficial and respectful partnerships with community based organizations and grass root level workers, the community became actively involved in clinical research. The program helped in developing a sense of partnership among the peers for the research conducted by the research organization, widening the net of community education and identification of research participants. By building trust in the community and implementing research within an ethical framework, culturally sensitive matters were appropriately addressed. The community involvement process is long, laborious and ever-evolving. Effective community engagement requires institutional leadership support, adequate funding and commitment by researchers. It is possible to sustain such a model in a resource limited setting.

During an emerging health crisis like the 2014 Ebola outbreak in West Africa, communicating with communities to learn from them and to provide timely information can be a challenge. Insight into community thinking, however, is crucial for developing appropriate communication content and strategies and for monitoring the progress of the emergency response. In November 2014, the Health Communication Capacity Collaborative partnered with GeoPoll to implement a Short Message Service (SMS)-based survey that could create a link with affected communities and help guide the communication response to Ebola. The ideation metatheory of communication and behavior change guided the design of the survey questionnaire, which produced critical insights into trusted sources of information, knowledge of transmission modes, and perceived risks-all factors relevant to the design of an effective communication response that further catalyzed ongoing community actions. The use of GeoPoll's infrastructure for data collection proved a crucial source of almost-real-time data. It allowed for rapid data collection and processing under chaotic field conditions. Though not a replacement for standard survey methodologies, SMS surveys can provide quick answers within a larger research process to decide on immediate steps for communication strategies when the demand for speedy emergency response is high. They can also help frame additional research as the response evolves and overall monitor the pulse of the situation at any point in time.

This study examined the perceptions of benefits of and barriers to participating in a community-based diabetes program to improve program effectiveness. The Diabetes Prevention and Management (DPM) program was a twenty-two session, 1-year program, modeled after the evidence-based National Diabetes Prevention Program and AADE7 Self-Care Behaviors framework. Community-based participatory research approach was used to culturally tailor the curriculum. Participants included overweight or obese adults with dysglycemia. A benefits and barriers survey was developed to gather information on participants' perception of the program, as well as information on demographics and health literacy levels. Eighty-nine adults participated in the DPM program (73% females; 62% diabetic; 77% had adequate health literacy); 79% of participants completed the benefits and barriers survey. Principal component analysis indicated two components representing benefits (Cronbach's α = 0.83) and barriers (α = 0.65). The majority perceived high benefits and low barriers to program participation; benefits included helpful interaction with health coach or program leader (73%), improved lifestyle modification (65%) due to the program, and satisfaction with the program (75%). Open-ended questions confirmed themes related to benefits of program participation, suggestion for programmatic improvements as well as barriers to participation. Participant feedback could be used to guide interventions and tailor future program implementation.
