Role theory: a framework to investigate the community nurse role in contemporary health care systems.

Science.gov (United States)

Brookes, Kim; Davidson, Patricia M; Daly, John; Halcomb, Elizabeth J

2007-01-01

Nurses' perceptions of their role are influenced by societal attitudes, government policies and trends in professional issues. Dynamic factors in contemporary health environments challenge traditional nursing roles, in particular those of community nurses. Role theory is a conceptual framework that defines how individuals behave in social situations and how these behaviours are perceived by external observers. This paper reviews the role theory literature as a conceptual framework to explore community nurses' perceptions of their role. Three theoretical perspectives of role theory have emerged from the literature review: 1. social structuralism 2. symbolic interactionism and 3. the dramaturgical perspective. These philosophical perspectives provide a useful framework to investigate the role of community nurses in the contemporary health care system.

Modern aluminium alloys for aeronautical applications. The role of the Al-Li system

International Nuclear Information System (INIS)

Godefroid, L.; Bernardes, A.T.; Bastian, F.L.

1995-01-01

A great effort has been made for some Aluminum Industries since the ''80 to develop new alloys with weight reduction, to use in aeronautic industry. The system Al-Li is a good example of this effort, because it presents a low density and a greater stiffness than usual alloys. In this paper we compare some Al-Li alloys with respect to mechanical properties: fracture toughness and resistance to crack propagation on fatigue case. The results are discussed, as well as the nowadays status and perspectives for the use of these alloys. (author)

An Overview of the NASA Aeronautics Test Program Strategic Plan

Science.gov (United States)

Marshall, Timothy J.

2010-01-01

U.S. leadership in aeronautics depends on ready access to technologically advanced, efficient, and affordable aeronautics test capabilities. These systems include major wind tunnels and propulsion test facilities and flight test capabilities. The federal government owns the majority of the major aeronautics test capabilities in the United States, primarily through the National Aeronautics and Space Administration (NASA) and the Department of Defense (DoD), however an overarching strategy for management of these national assets was needed. Therefore, in Fiscal Year (FY) 2006 NASA established the Aeronautics Test Program (ATP) as a two-pronged strategic initiative to: (1) retain and invest in NASA aeronautics test capabilities considered strategically important to the agency and the nation, and (2) establish a strong, high level partnership with the DoD Test Resources Management Center (TRMC), stewards of the DoD test and evaluation infrastructure. Since then, approximately seventy percent of the ATP budget has been directed to underpin fixed and variable costs of facility operations within its portfolio and the balance towards strategic investments in its test facilities, including maintenance and capability upgrades. Also, a strong guiding coalition was established through the National Partnership for Aeronautics Testing (NPAT), with governance by the senior leadership of NASA s Aeronautics Research Mission Directorate (ARMD) and the DoD's TRMC. As part of its strategic planning, ATP has performed or participated in many studies and analyses, including assessments of major NASA and DoD aeronautics test capabilities, test facility condition evaluations and market research. The ATP strategy has also benefitted from unpublished RAND research and analysis by Ant n et al. (2009). Together, these various studies, reports and assessments serve as a foundation for a new, five year strategic plan that will guide ATP through FY 2014. Our vision for the future is a balanced

Emerging Options and Opportunities in Civilian Aeronautics

Bushnell, Dennis M.

2012-01-01

This paper addresses the major problems/issues with civilian aeronautics going forward, the contextual ongoing technology revolutions, the several emerging civilian aeronautical "Big Ideas" and associated enabling technological approaches. The ongoing IT Revolution is increasingly providing, as 5 senses virtual presence/reality becomes available, along with Nano/Molecular Manufacturing, virtual alternatives to Physical transportation for both people and goods. Paper examines the potential options available to aeronautics to maintain and perhaps grow "market share" in the context of this evolving competition. Many of these concepts are not new, but the emerging technology landscape is enhancing their viability and marketability. The concepts vary from the "interesting" to the truly revolutionary and all require considerable research. Paper considers the speed range from personal/general aviation to supersonic transports and technologies from energetics to fabrication.

Although the theoretical/ moral answer would be affirmative (universities should be in such a position that would allow local communities to regard them as role models of gender integration, the primary empirical analysis leads to another conclusion. A brief theoretical review (that connects gender discrimination, sustainable development, universities and local communities is followed by an empirical analysis that compares the management structures of 12 Romanian Universities of Advanced Research and Education (the best Romanian universities according to a national ranking with those of four local communities where they are located (as geographic proximity would lead to a better diffusion of best practices. Contrary to initial expectations, even in higher education institutions, women are underrepresented both in executive and legislative positions. Since universities are subject to the same major patterns of gender discrimination (such as role theory, glass ceiling and glass elevator as private and public organizations, they lose the moral high ground that theory would suggest. However, medicine and pharmacy universities that can be connected with the traditional roles attributed to women provide better gender integration, but glass escalator phenomena remain present even in these limited fields.

Community perceptions and attitudes on malaria case management and the role of community health workers.

Science.gov (United States)

Owek, Collins J; Oluoch, Elizabeth; Wachira, Juddy; Estambale, Benson; Afrane, Yaw A

2017-07-04

Community Case Management of malaria (CCMm) is one of the new approaches adopted by the World Health Organization for malaria endemic countries to reduce the burden of malaria for vulnerable populations. It is based on the evidence that well-trained and supervised community health workers (CHWs) can provide prompt and adequate treatment to fever cases within 24 h to help reduce morbidity and mortality associated with malaria among under-five children. The perception and attitudes of the community members on the CHWs' role is of greater importance for acceptance of their services. The aim of the study was to assess community's perception and attitude towards CCMm and on CHWs who undertake it. This study was conducted in five districts in western Kenya where Community Case Management was being undertaken. This was a qualitative cross-sectional study in which in-depth interviews and focus group discussions were conducted with mothers of under-five children and key stakeholders. Overall, there were more positive expressions of perceptions and attitudes of the community members towards the CCMm programme and the role of CHWs. The positive perceptions included among others; recognition and appreciation of services of CHWs, bringing health services to close proximity to the community, avoiding long queues in the health facilities, provision of health education that encourages good health practices, and promotion of positive health-seeking behaviour from within the communities. This programme is not without challenges as some of the negative perceptions expressed by the community members included the fact that some clinicians doubt the capacity of CHWs on dispensing drugs in the community, some CHWs do not keep client's secrets and mistrust of CHWs due to conflicting information by government. It was evident that the community had more positive perceptions and attitudes towards the role of CHWs in CCMm than negative ones. There should however, be deliberate efforts

2011-09-01

Community health nurses (CHNs), as leaders in developing countries, can promote successful outcomes in meeting the targets of the Millennium Development Goals. A community-based organization in Pakistan is striving to achieve the goals of maternal and child health through the development of the assistant manager role for community health nursing. The purpose of this study was to assess the perception of the role of the CHN assistant manager, with the goal of strengthening that role. This interpretive, qualitative study included 13 participants already familiar with CHNs in Pakistan. Interviewing was utilized to explore perceptions of the assistant manager role and to uncover challenges currently existing within this new role. Content analysis revealed the following themes: 'role perceptions', 'expectations of the role' and 'collaboration with other community healthcare providers'. Changes to the role are necessary including increased education of the assistant manager CHNs and preparing administration to work with the assistant mangers for effective leadership. © 2011 The Authors.

2015-10-01

Full Text Available Civil aviation is developing rapidly, and the number of domestic and international operations is increasing exponentially every year than the previous one. Airline companies with increased air traffic and the number of passengers increase the demand of new aircrafts. An aircraft needs not only fuel but also pilot and aeronautical information (charts, digital navigation information, flight plan, and etc. to perform flight operation. One of the most important components in aeronautical information is the terminal chart. Authorized institution in every state is responsible to publish their terminal charts for certain periods. Although these charts are produced in accordance with ICAO’s Annex 4 and Annex 15, cartographic representation and page layout differs in each state’s publication. This situation makes difficult to read them by pilots. In this paper, standard instrument departure (SID charts are analysed to produce by use of cutting-edge and competitive technologies instead of classical computer-aided drawing and vector based graphic applications that are currently used by main chart producers. The goal is to design efficient and commercial chart management system that is able to produce aeronautical charts with same cartographic representation for all states.

Do Faith Communities Have a Role in Addressing Childhood Obesity?

Science.gov (United States)

Opalinski, Andra; Dyess, Susan; Grooper, Sareen

2015-01-01

Pediatric obesity is a multifaceted phenomenon. A partnership with faith-based communities to address the issue has been suggested. The purpose of this study was to describe the cultural beliefs of faith community leaders regarding childhood obesity and to examine attitudes about their role in addressing the issue. A qualitative descriptive design informed by ethnographic methods and triangulation of multiple data sources was utilized to assess the cultural beliefs of faith community leaders. A purposive sample of 13 leaders (nine females, four males) from seven multicultural and multigenerational local faith communities participated in the study. No more than three participants from any one faith community were enrolled in the study. Twenty-first century lifestyle challenges, accountability of behaviors (a dichotomy that fluctuated between individual responsibility to community and/or social responsibility), and the need for intentionality emerged as themes from the data. Faith community leaders envisioned a role for faith communities in addressing childhood obesity. Findings support the ongoing development of population based health promotion programs through faith community engagement. The findings provide a foundation for nurses partnering with faith communities on health promotion programs targeting childhood obesity to address family health issues in a holistic way. © 2015 Wiley Periodicals, Inc.

Influence of ownership type on role orientation, role affinity, and role conflict among community pharmacy managers and owners in Canada.

2010-12-01

Ownership of community pharmacies is increasingly being controlled by a relatively small number of corporate entities. The influence of this ownership type should not be ignored, because ownership has the ability to impact pharmacy practice. To examine the relationship between ownership type and community pharmacy managers with regard to role orientation, role affinity, and role conflict. This study consisted of a cross-sectional survey of community pharmacy managers in Canada by means of a self-administered postal questionnaire sent to a stratified sample of community pharmacies. Statistical analysis consisted of exploratory factor analysis with reliability testing on identified constructs. Frequencies, 1-way analyses of variance, and Scheffe post hoc tests were used to determine significant differences among groups, including ownership structure, on each of the constructs. A total of 646 completed questionnaires were received (32.9% response rate). Most of the respondents were males (60.8%), with slightly less than half of the respondents identifying their practice type as an independent pharmacy (44.6%). There were 5 multi-item scale constructs (professional orientation, business orientation, professional affinity, business affinity, and role conflict) arising from the data, which were analyzed against the pharmacy ownership structure (independent, franchise, corporate) independent variable. Analysis revealed significant differences for 3 of the 5 constructs; however, no differences were seen regarding the 2 professionally focused constructs. Community pharmacy managers/owners are generally oriented to their professional role; however, those working in a corporate pharmacy environment are less oriented to their business role when compared with those working in an independent or franchise pharmacy environment. Further research is needed to identify different practice cultures that may exist in various practice settings and the extent to which these cultures

Community health workers (CHWs) are an integral resource in many health systems, particularly in resource-poor settings. Their identities--'who' they are--play an important role in their hiring, training, and retention. We explore the perceptions, experiences, and identities of CHWs as they adopt a CHW role in rural South Africa, using 'role identity theory'. From April to December 2010, we conducted 18 semi-structured interviews with CHWs volunteering in non-governmental home-based care (HBC) organisations in one rural sub-district in South Africa. The role identity theory framework was used to understand the work of CHWs within their communities, addressing themes, such as entry into, and nature of, caring roles, organisational support, state resourcing, and community acceptability. A thematic content analysis was used to analyse the collected data. The study found that CHWs usually begin their 'caring work' before they formally join HBC organisations, by caring for children, neighbours, mothers, fathers, friends, and the community in some way. CHWs felt that becoming a health worker provided an elevated status within the community, but that it often led community members to believe they were able to control resources. The key role identities assumed by CHWs, as they sought to meet patients' and their own needs, were a complex mix of community 'insider', 'outsider', and 'broker'. Each of these role identities served as a unique way to position, from the CHW's perspective, themselves and the community, given the diversity of needs and expectations. These role identities reveal the tensions CHWs face as 'insider' members of the community and yet at times being treated as 'outsiders', who might be regarded with suspicion, and at the same time, appreciated for the resources that they might possess. Understanding role identities, and how best to support them, may contribute to strategies of retention and sustainability of CHW programmes, as their formalisation in

The emissivity of three Ni and Co based aeronautical alloys is analyzed in this paper. These alloys are employed in high temperature environments whenever good corrosion resistance, high temperature resistance and high strength are essential. Thus, apart from the aeronautical industry, these alloys are also used in other technological applications, as for example, aerospace, nuclear reactors, and tooling. The results in this paper extend the emissivity data for these alloys available in the literature. Emissivity dependence on the radiation wavelength (2-22 μm), sample temperature (200-650 o C) and emission angle (0-85 o ) has been investigated. In addition, the effect of surface finish and oxidation has also been taken into consideration. The data in this paper have several applications, as temperature measurement of a target by pyrometry, low observability of airplanes and thermal radiation heat transfer simulation in airplane nozzles or furnaces.

Full Text Available In any discourse on sociology and anthropology, one fact that clearly emerges is that women can generally be trusted to perform their duties with utmost care and attention. This is more so in the case of agriculture and allied activities. No wonder women are playing a very important role in the sericulture industry. Their qualities like maternal instincts and loving care of those under their charge prove to be very helpful in the successful breeding of silk worms. The sericulture industry has opened up phenomenal employment avenues and helped women to become important players in the decision-making process—whether in the household or in the community at large. The active involvement of women is very essential for the success of the any community development initiative. This has been proved on many occasions all over the world—more so in the developing countries. For instance, the success of Self Help Groups (SHGs in Andhra Pradesh and other states of India is all due to the active role played by women. The thrust of this article is on the role of women in promotion of sericulture activities in the village, and how their participation has led to community development. Given the above backdrop, the present article is based on an empirical work undertaken in Kotha Indlu village, Chittoor District of Andhra Pradesh in South India. Sericulture is an important means for generating employment, income enhancement crop enterprises, and is a most appropriate household activity.

Texter, P. Cardie

1998-01-01

The National Aeronautics and Space Administration funded project, Aeronautics and Aviation Science: Careers and Opportunities has been in operation since July, 1995. This project operated as a collaboration with Massachusetts Corporation for Educational Telecommunications, the Federal Aviation Administration, Bridgewater State College and four targeted "core sites" in the greater Boston area. In its first and second years, a video series on aeronautics and aviation science was developed and broadcast via "live, interactive" satellite feed. Accompanying teacher and student supplementary instructional materials for grades 6-9 were produced and disseminated by the Massachusetts Corporation for Educational Telecommunications (MCET). In the MCET grant application it states that project Take Off! in its initial phase would recruit and train teachers at "core" sites in the greater Boston area, as well as opening participation to other on-line users of MCET's satellite feeds. "Core site" classrooms would become equipped so that teachers and students might become engaged in an interactive format which aimed at not only involving the students during the "live" broadcast of the instructional video series, but which would encourage participation in electronic information gathering and sharing among participants. As a Take Off! project goal, four schools with a higher than average proportion of minority and underrepresented youth were invited to become involved with the project to give these students the opportunity to consider career exploration and development in the field of science aviation and aeronautics. The four sites chosen to participate in this project were: East Boston High School, Dorchester High School, Randolph Junior-Senior High School and Malden High School. In year 3 Dorchester was unable to continue to fully participate and exited out. Danvers was added to the "core site" list in year 3. In consideration of Goals 2000, the National Science Foundation

Community structures and role detection in music networks

Teitelbaum, T.; Balenzuela, P.; Cano, P.; Buldú, Javier M.

2008-12-01

We analyze the existence of community structures in two different social networks using data obtained from similarity and collaborative features between musical artists. Our analysis reveals some characteristic organizational patterns and provides information about the driving forces behind the growth of the networks. In the similarity network, we find a strong correlation between clusters of artists and musical genres. On the other hand, the collaboration network shows two different kinds of communities: rather small structures related to music bands and geographic zones, and much bigger communities built upon collaborative clusters with a high number of participants related through the period the artists were active. Finally, we detect the leading artists inside their corresponding communities and analyze their roles in the network by looking at a few topological properties of the nodes.

Wilkins, Ryan; Zernic, Michael; Dhas, Chris

2004-01-01

Aviation industries in United States and in Europe are undergoing a major paradigm shift in the introduction of new network technologies. In the US, NASA is also actively investigating the feasibility of IPv6 based networks for the aviation needs of the United States. In Europe, the Eurocontrol lead, Internet Protocol for Aviation Exchange (iPAX) Working Group is actively investigating the various ways of migrating the aviation authorities backbone infrastructure from X.25 based networks to an IPv6 based network. For the last 15 years, the global aviation community has pursued the development and implementation of an industry-specific set of communications standards known as the Aeronautical Telecommunications Network (ATN). These standards are now beginning to affect the emerging military Global Air Traffic Management (GATM) community as well as the commercial air transport community. Efforts are continuing to gain a full understanding of the differences and similarities between ATN and Internet architectures as related to Communications, Navigation, and Surveillance (CNS) infrastructure choices. This research paper describes the implementation of the IPv6 test bed at NASA GRC, and Computer Networks & Software, Inc. and these two test beds are interface to Eurocontrol over the IPv4 Internet. This research work looks into the possibility of providing QoS performance for Aviation application in an IPv6 network as is provided in an ATN based network. The test bed consists of three autonomous systems. The autonomous system represents CNS domain, NASA domain and a EUROCONTROL domain. The primary mode of connection between CNS IPv6 testbed and NASA and EUROCONTROL IPv6 testbed is initially a set of IPv6 over IPv4 tunnels. The aviation application under test (CPDLC) consists of two processes running on different IPv6 enabled machines.

The role of content marketing in social media content communities

Directory of Open Access Journals (Sweden)

Charmaine du Plessis

2017-10-01

Full Text Available Background: Content marketing has become a leading marketing technique in digital marketing communication and uses the point of view of consumers to build relationships by creating and sharing engaging content in social media that enhance their daily lives. Existing research on social media communities has focused mainly on social media marketing and virtual brand community perspectives while content marketing’s valuable and unobtrusive role in social media content communities has largely been overlooked. Objective: The purpose of this article was to investigate content marketing’s role in social media content communities to engage with the target audience in an innate manner. Method: This study made use of a directed, inductive content analysis of 51 practitioner documents relating to business-to-consumer content marketing practices to add another perspective to existing research on communities in social media. The content analysis was facilitated by using QDA Miner, a widely adopted and reliable qualitative data analysis software programme. Results: Three categories emerged from the data namely building content communities, platform-specific content and understanding channels. These categories provide sufficient evidence of how brands make use of social media content communities to connect with the target audience in an unobtrusive manner, in addition to being present in virtual brand communities. Conclusion: The findings make several contributions to the existing literature. Firstly, it provides a clearer distinction between brand and social media content communities. Secondly, it extends conceptions about social media communities to include content communities and, thirdly, it provides sufficient evidence of how content marketing could benefit a brand by naturally becoming part of social media conversations.

The community health worker, known as promotor in the Hispanic community, is an accepted member of the public health team whose core role is that of bridging target communities with health services. However, the promotor's role in research has not been considered a core function of their work. This article will present the promotor in the additional role of researcher, as conceived by the Migrant Clinicians Network for the Hombres Unidos Contra La Violencia Familiar (Men United Against Family Violence) sexual violence/intimate partner violence project. The Hombres Unidos project used promotores as survey facilitators, gathering male Hispanic farmworkers' perspectives on the sensitive topic of sexual violence and intimate partner violence. This article demonstrates that when trained, the promotores' linguistic and cultural competence make them a valuable addition to the research team, especially when collecting sensitive information.

Community healing and the role of pastoral care of the ill and suffering in Africa

Directory of Open Access Journals (Sweden)

V. Magezi

2006-07-01

Full Text Available The extended family (community in Africa plays a crucial role in the process of healing. However, while the role of the community is invaluable, many scholars overlook its other side. This article argues for a critical consideration of the healing role of the community in Africa and offers a critique of African community healing in the light of pastoral healing. Pastoral healing as a spiritual and faith perspective is juxtaposed with the healing process within African traditional communities. Since these two communities operate from different perspectives, in many cases they are competing forces in the process of healing – a difference that aggravates pain. This article thus carefully describes the process of healing both within a faith community (with its acts of “koinonia” and the African traditional community, and concludes by proposing a healthy integration of these systems.

Eswarlal, Vimal Kumar; Vasudevan, Geoffrey; Dey, Prasanta Kumar; Vasudevan, Padma

2014-01-01

Community acceptance has been identified as one of the key requirements for a sustainable bioenergy project. However less attention has been paid to this aspect from developing nations and small projects perspective. Therefore this research examines the role of community acceptance for sustainable small scale bioenergy projects in India. While addressing the aim, this work identifies influence of community over bioenergy projects, major concerns of communities regarding bioenergy projects and factors influencing perceptions of communities about bioenergy projects. The empirical research was carried out on four bioenergy companies in India as case studies. It has been identified that communities have significant influence over bioenergy projects in India. Local air pollution, inappropriate storage of by-products and credibility of developer are identified as some of the important concerns. Local energy needs, benefits to community from bioenergy companies, level of trust on company and relationship between company and the community are some of the prime factors which influence community's perception on bioenergy projects. This research sheds light on important aspects related to community acceptance of bioenergy projects, and this information would help practitioners in understanding the community perceptions and take appropriate actions to satisfy them

Community reactions to disaster: An emerging role for the school psychologist

Directory of Open Access Journals (Sweden)

Bernie Stein

2016-02-01

Full Text Available This article will describe ways in which communities react to severe crises, both on a local and on a national level. Based on experiences in Israel over the past twenty years, including recent traumatic events such as the assassination of prime minister Yitzhak Rabin and the terrorist suicide bombings, and on an intervention in Buenos Aires, Argentina, after the bombing of the Jewish Community Centre in July 1994, a model is presented to describe different stages of reaction. The importance of the creation and development of community prevention and intervention programs is stressed. Emphasis is placed on the role of the schools and the school psychologists in developing and implementing such programs, and on their critical role in dealing immediately with crisis situations and their aftermaths. The prevention program emphasizes the fostering of inner strengths and resources in children and teachers (‘inoculation’, and makes provision for dealing with emotional support for the professionals in charge of helping the community in times of crisis. Finally, a model for the future development of the profession of school psychology into a broader community service is proposed.

Hatch, Julie

2012-01-01

Neonatal nurse practitioners (NNPs) have played a significant role in providing medical coverage to many of the country's Level III neonatal intensive care units (NICUs). Extensive education and experience are required for a nurse practitioner (NP) to become competent in caring for these critically ill newborns. The NNP can take this competence and experience and expand her role out into the community Level I nurseries. Clinical care of the infants and close communication with parents, pediatricians, and the area tertiary center provide a community service with the goal of keeping parents and babies together in the community hospital without compromising the health of the baby. The NNP service, with 24-hour nursery and delivery coverage, supports an ongoing obstetric service to the community hospital. The NNP's experience enables her to provide a neonatal service that encompasses a multitude of advanced practice nursing roles.

This paper reviews recent developments in energy harvesting technologies for structural health monitoring (SHM) in aeronautical applications. Aeronautical industries show a great deal of interest in obtaining technologies that can be used to monitor the health of machinery and structures. In particular, the need for self-sufficient monitoring of structures has been ever-increasing in recent years. Autonomous SHM systems typically include embedded sensors, and elements for data acquisition, wireless communication, and energy harvesting. Among all of these components, this paper focuses on energy harvesting technologies. Actually, low-power sensors and wireless communication components are used in newer SHM systems, and a number of researchers have recently investigated such techniques to extract energy from the local environment to power these stand-alone systems. The first part of the paper is dedicated to the different energy sources available in aeronautical applications, i.e., for airplanes and helicopters. The second part gives a presentation of the various devices developed for converting ambient energy into electric power. The last part is dedicated to a comparison of the different technologies and the future development of energy harvesting for aeronautical applications.

, and this is particularly apparent in the South Asian countries, including Nepal. Despite the growing burden and chronic nature of type 2 diabetes, prevention and control of this disease is far from adequate in these settings. One possibility could be through the involvement of community health workers to prevent, diagnose...... and treat type 2 diabetes. We suggest that involving Female Community Health Volunteers (FCHVs) of Nepal offering culturally appropriate health promotion may be the blue print for community-based management programmes tackling type 2 diabetes. We aim to explore the potential role of FCHVs of Nepal...... for diabetes management at community level. It is anticipated that the study can give valuable information regarding effectiveness, acceptability, and feasibility of an innovative way to improve diabetes management in low resource settings....

A Glimpse of Scientific Research on Fundamental Problems of Military and Civil Aeronautics

Science.gov (United States)

1939-01-01

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

Children's health outcomes result from the complex interaction of biological determinants with sociocultural, family, and community variables. Dental professionals' efforts to reduce oral health disparities often focus on improving access to dental care. However, this strategy alone cannot eliminate health disparities. Rising rates of early childhood caries create an urgent need to study family and community factors in oral health. Using Los Angeles as a multicultural laboratory for understanding health disparities, the Santa Fe Group convened an experiential conference to consider models of ensuring child and family health within communities. This article summarizes key conference themes and insights regarding 1) children's needs and societal priorities; 2) the science of child health determinants; 3) the rapidly changing demographics of the United States; and 4) the importance of communities that support children and families. Conference participants concluded that to eliminate children's oral health disparities we must change paradigms to promote health, integrate oral health into other health and social programs, and empower communities. Oral health advocates have a key role in ensuring oral health is integrated into policy for children. Dental schools have a leadership role to play in expanding community partnerships and providing education in health determinants. Participants recommended replicating this experiential conference in other venues.

Department of Community Medicine at Fatima Memorial College of Medicine and Dentistry from July to November 2010. A probability technique of simple random sampling was used to collect 63 students from the third and fourth year MBBS who were randomly distributed in five sub-groups. They were variously ascribed the roles of obsceners, participants and helpers. A questionnaire was distributed to collect student's responses. The data was analyzed on SPSS version 17 to compare the responses. Chi-square test was applied and p-value was fixed at andragogy (p = 0.005) and 48 (76.2%) said that it provoked critical thinking about the subject (p = 0.038). Fifty-four students (85.7%) admitted that their attention span was better in role-plays as compared to lectures (p = 0.047). Role-plays were well accepted by the students as an effective teaching methodology and can be incorporated as a part of teaching strategies in Community Medicine.

Role of optical computers in aeronautical control applications

Science.gov (United States)

Baumbick, R. J.

1981-01-01

The role that optical computers play in aircraft control is determined. The optical computer has the potential high speed capability required, especially for matrix/matrix operations. The optical computer also has the potential for handling nonlinear simulations in real time. They are also more compatible with fiber optic signal transmission. Optics also permit the use of passive sensors to measure process variables. No electrical energy need be supplied to the sensor. Complex interfacing between optical sensors and the optical computer is avoided if the optical sensor outputs can be directly processed by the optical computer.

Full Text Available Background: Community health workers (CHWs are increasingly being recognised as a crucial part of the health workforce in South Africa and other parts of the world. CHWs have taken on a variety of roles, including community empowerment, provision of services and linking communities with health facilities. Their roles are better understood in the areas of maternal and child health and infectious diseases (HIV infection, malaria and tuberculosis. Aim: This study seeks to explore the current roles of CHWs working with non-communicable diseases (NCDs. Setting: The study was conducted in an urban township in Cape Town, South Africa. Method: A qualitative naturalistic research design utilising observations and in-depth interviews with CHWs and their supervisors working in Khayelitsha was used. Results: CHWs have multiple roles in the care of NCDs. They act as health educators, advisors, rehabilitation workers and support group facilitators. They further screen for complications of illness and assist community members to navigate the health system. These roles are shaped both by expectations of the health system and in response to community needs. Conclusion: This study indicates the complexities of the roles of CHWs working with NCDs. Understanding the actual roles of CHWs provides insights into not only the competencies required to enable them to fulfil their daily functions, but also the type of training required to fill the present gaps.

The Role of Nurses in Community Awareness and Preventive Health

as a theoretical framework within that community should be considered to help explain how communities address adversity.2 In a British study, researchers established the importance of the role of nursing in preventive health when nurses added significant improvement to reduce the major risk factors for cardiovascular disease in middle aged patients. Nurses, compared to other healthcare providers, were able to provide health screening and doubled the recorded blood pressure, quadrupled identification of smoking habit, and increased documented weight related issues by fivefold in a primary care setting.3 Community health nursing theory addresses collective concepts of nursing domains in an attempt to rectify environmental, resiliency, and community abilities for healthcare issues among diverse population and avoids simple groupings of aggregates. Conceptual frameworks are introduced to help urban and rural communities implement preventative measures for health and wellbeing of residents through rural-based community health nursing programs.1,4 With this awareness, Iranian nurses in any practice area will find a golden opportunity to encourage, motivate, inform and guide the public to consider health screening, annual check-ups, childhood and adult immunizations and offer health education to patients across the lifespan. The role of nursing does not begin or end in a hospital-based or clinical facility. It is important to remember “Once a nurse, Always a nurse”, which means a nurse can guide and educate the public every minute and in all places, for the mere fact that medicine does NOT. Community health is a major part of nursing profession as Sarah, who graduated from a baccalaureate nursing program 5 years ago, demonstrates her role as a spiritual journey with a firm belief to bring health awareness through motivation. Her usual day begins by telling a 45 year-old male cashier in a supermarket to go for a prostate cancer screening; a 50 year-old woman sitting in

In support of the ongoing effort by the National Aeronautics and Space Administration (NASA) to bring supersonic commercial travel to the public, the NASA Armstrong Flight Research Center and the NASA Langley Research Center, in cooperation with other industry organizations, conducted a flight research experiment to identify the methods, tools, and best practices for a large-scale quiet (or low) sonic boom community human response test. The name of the effort was Waveforms and Sonic boom Perception and Response (WSPR). Such tests will be applied to building a dataset that governing agencies such as the Federal Aviation Administration and the International Civil Aviation Organization will use to establish regulations for acceptable sound levels of overland sonic booms. The WSPR test was the first such effort that studied responses to non-traditional low sonic booms while the subject persons were in their own homes and performing daily activities.The WSPR test was a NASA collaborative effort with several industry partners, in response to a NASA Aeronautics Research Mission Directorate Research Opportunities in Aeronautics. The primary contractor was Wyle (El Segundo, California). Other partners included Gulfstream Aerospace Corporation (Savannah, Georgia); Pennsylvania State University (University Park, Pennsylvania); Tetra Tech, Inc. (Pasadena, California); and Fidell Associates, Inc. (Woodland Hills, California).A major objective of the effort included exposing a community to the sonic boom magnitudes and occurrences that would be expected to occur in high-air traffic regions having a network of supersonic commercial aircraft in place. Low-level sonic booms designed to simulate those produced by the next generation of commercial supersonic aircraft were generated over a small residential community. The sonic boom footprint was recorded with an autonomous wireless microphone array that spanned the entire community. Human response data were collected using multiple

Building capacity for low-carbon communities: The role of grassroots initiatives

International Nuclear Information System (INIS)

Middlemiss, Lucie; Parrish, Bradley D.

2010-01-01

Grassroots initiatives for change rely on people with limited power, limited resources and limited ability to influence others. From this position, people acting from the bottom up can change their own actions, seek to influence others around them and seek to change the social structures that they inhabit. These acts are invariably conceived, initiated and enacted within communities, and there is an emerging interest from practitioner, policy and academic circles in the importance of community as a space for realising pro-environmental change. In this paper, we ask what role grassroots initiatives can have in creating low-carbon communities. Using a theoretical framework from work on community-based practice change initiatives, we discuss the interplay between grassroots action and community capacity. We then present two cases of grassroots low-carbon community initiatives in light of this theoretical work. We conclude by discussing key themes emerging from the cases, including the potential for grassroots initiatives to build community capacity for low-carbon practices, and the importance of locally crafted solutions according to the structures specific to place.

Lessons Learned for Online Health Community Moderator Roles: A Mixed-Methods Study of Moderators Resigning From WebMD Communities

Science.gov (United States)

Marmor, Rebecca; Jiang, Xiaoqian

2016-01-01

Background Online health community (OHC) moderators help facilitate conversations and provide information to members. However, the necessity of the moderator in helping members achieve goals by providing the support they need remains unclear, with some prior research suggesting that moderation is unnecessary or even harmful for close-knit OHCs. Similarly, members’ perceptions of moderator roles are underexplored. Starting January of 2013, WebMD moderators stopped working for WebMD communities. This event provided an opportunity for us to study the perceived role of moderators in OHCs. Objective We examine the OHC members’ perception on OHC moderators by studying their reactions toward the departure of moderators in their communities. We also analyzed the relative posting activity on OHCs before and after the departure of moderators from the communities among all members and those who discussed moderators’ departures. Methods We applied a mixed-methods approach to study the posts of all 55 moderated WebMD communities by querying the terms relating to discussions surrounding moderators’ disappearance from the WebMD community. We performed open and axial coding and affinity diagramming to thematically analyze patients’ reactions to the disappeared moderators. The number of posts and poster groups (members and moderators) were analyzed over time to understand posting patterns around moderators’ departure. Results Of 821 posts retrieved under 95 threads, a total of 166 open codes were generated. The codes were then grouped into 2 main themes with 6 total subthemes. First, patients attempted to understand why moderators had left and what could be done to fill the void left by the missing moderators. During these discussions, the posts revealed that patients believed that moderators played critical roles in the communities by making the communities vibrant and healthy, finding solutions, and giving medical information. Some patients felt personally attached

Robust Control of Aeronautical Electrical Generators for Energy Management Applications

Directory of Open Access Journals (Sweden)

Giacomo Canciello

2017-01-01

Full Text Available A new strategy for the control of aeronautical electrical generators via sliding manifold selection is proposed, with an associated innovative intelligent energy management strategy used for efficient power transfer between two sources providing energy to aeronautical loads, having different functionalities and priorities. Electric generators used for aeronautical application involve several machines, including a main generator and an exciter. Standard regulators (PI or PID-like are normally used for the rectification of the generator voltage to be used to supply a high-voltage DC bus. The regulation is obtained by acting on a DC/DC converter that imposes the field voltage of the exciter. In this paper, the field voltage is fed to the generator windings by using a second-order sliding mode controller, resulting into a stable, robust (against disturbances action and a fast convergence to the desired reference. By using this strategy, an energy management strategy is proposed that dynamically changes the voltage set point, in order to intelligently transfer power between two voltage busses. Detailed simulation results are provided in order to show the effectiveness of the proposed energy management strategy in different scenarios.

Hunter, Gary W.; Chen, Liang-Yu; Neudeck, Philip G.; Knight, Dak; Liu, Chung-Chiun; Wu, Quing-Hai; Zhou, Huan-Jun

1997-01-01

Aeronautic and space applications require the development of chemical sensors with capabilities beyond those of commercially available sensors. Two areas of particular interest are safety monitoring and emission monitoring. In safety monitoring, detection of low concentrations of hydrogen at potentially low temperatures is important while for emission monitoring the detection of nitrogen oxides, hydrogen, hydrocarbons and oxygen is of interest. This paper discusses the needs of aeronautic and space applications and the point-contact sensor technology being developed to address these needs. The development of these sensors is based on progress in two types of technology: (1) Micromachining and microfabrication technology to fabricate miniaturized sensors. (2) The development of high temperature semiconductors, especially silicon carbide. The detection of each type of gas involves its own challenges in the fields of materials science and fabrication technology. The number of dual-use commercial applications of this microfabricated gas sensor technology make this general area of sensor development a field of significant interest.

Doing emotion work in museums: reconceptualising the role of community engagement practitioners

Directory of Open Access Journals (Sweden)

Ealasaid Munro

2014-03-01

Full Text Available In this paper I investigate the practice of community engagement, and suggest that ideas around emotion work and emotional labour might offer new ways of thinking about the role of museum staff in community engagement settings. Through material gathered as part of an ethnographic research project conducted with Glasgow Museums - the city of Glasgow’s municipal museums service - I show that community engagement practitioners routinely utilize emotional performances as part of their work. I argue that, often, the emotion work that is done in these settings is under-valued, and suggest that both scholars of museums and museum professionals need to pay more attention to the interpersonal relationships that might be forged within community engagement settings.

Supporting the role of community members employed as research staff: Perspectives of community researchers working in addiction research.

Science.gov (United States)

True, Gala; Alexander, Leslie B; Fisher, Celia B

2017-08-01

Community researchers are laypersons who conduct research activities in their own communities. In addiction and HIV research, community researchers are valued for their insider status and knowledge. At the same time, their presence on the research team raises concerns about coercion and confidentiality when community researchers and participants know each other personally, and the work of navigating between the worlds of research and community leads to moral distress and burnout for some community researchers. In this paper, we draw upon the concept of 'moral experience' to explore the local moral worlds of community researchers in the context of addiction research. In February and March 2010, we conducted focus groups with 36 community researchers employed on community-based addiction studies in the United States to elicit perspectives on ethical and moral challenges they face in their work and insights on best practices to support their role in research. Community researchers described how their values were realized or thwarted in the context of research, and their strategies for coping with shifting identities and competing priorities. They delineated how their knowledge could be used to inform development of research protocols and help principal investigators build and maintain trust with the community researchers on their teams. Our findings contribute to current understandings of the moral experiences of community members employed in research, and inform policies and practices for the growing field of community-engaged research. Funders, research organizations, and research ethics boards should develop guidelines and standards to ensure studies have key resources in place to support community researchers and ensure quality and integrity of community-engaged work. Investigators who work with community researchers should ensure channels for frontline staff to provide input on research protocols and to create an atmosphere where challenges and concerns can be

Take Off! Aeronautics and Aviation Science: Careers and Opportunities

Science.gov (United States)

1998-01-01

Funded by National Aeronautic and Space Administration's High Performance Computing and Communications/ Learning Technologies Project (HPCC/LTP) Cooperative Agreement, Aeronautics and aviation Science: Careers and Opportunities was operative from July 1995 through July 1998. This project operated as a collaboration with Massachusetts Corporation for Educational Telecommunications, the Federal Aviation Administration, Bridgewater State College and four targeted "core sites" in the greater Boston area: Dorchester, Malden, East Boston and Randolph. In its first and second years, a video series with a participatory website on aeronautics and aviation science was developed and broadcast via "live, interactive" satellite feed. Accompanying teacher and student supplementary instructional materials for grades 6-12 were produced and disseminated by the Massachusetts Corporation for Educational Telecommunications (MCET). In year three, the project team redesigned the website, edited 14 videos to a five part thematic unit, and developed a teacher's guide to the video and web materials supplement for MAC and PC platforms, aligned with national standards. In the MCET grant application it states that project Take Off! in its initial phase would recruit and train teachers at "core" sites in the greater Boston area, as well as opening participation to other on-line users of MCET's satellite feeds. "Core site" classrooms would become equipped so that teachers and students might become engaged in an interactive format which aimed at not only involving the students during the "live" broadcast of the instructional video series, but which would encourage participation in electronic information gathering and sharing among participants. As a Take Off! project goal, four schools with a higher than average proportion of minority and underrepresented youth were invited to become involved with the project to give these students the opportunity to consider career exploration and development

The forecasting of reliability and life of aeronautical hardware requires recognition of many and various destructive processes that deteriorate the health/maintenance status thereof. The aging of technical components of aircraft as an armament system proves of outstanding significance to reliability and safety of the whole system. The aging process is usually induced by many and various factors, just to mention mechanical, biological, climatic, or chemical ones. The aging is an irreversible process and considerably affects (i.e. reduces) reliability and lifetime of aeronautical equipment. Application of the characteristic function of the aging process is suggested to predict reliability and lifetime of aeronautical hardware. An increment in values of diagnostic parameters is introduced to formulate then, using the characteristic function and after some rearrangements, the partial differential equation. An analytical dependence for the characteristic function of the aging process is a solution to this equation. With the inverse transformation applied, the density function of the aging of aeronautical hardware is found. Having found the density function, one can determine the aeronautical equipment’s reliability and lifetime. The in-service collected or the life tests delivered data are used to attain this goal. Coefficients in this relationship are found using the likelihood function.

Role of Nurses in Community Mental Health Centers: Example of England

Directory of Open Access Journals (Sweden)

Beyhan Bag

2012-12-01

Full Text Available The goal of the community mental health centers, which constitute the core of community based mental health service model, is to register the patients who live in a certain geographical region and have serious mental disorder in the center, to observe them regularly and to bring them back to community by providing their rehabilitation and treatment. The practice of community based mental health, which English health service carries out in one hand for the psychiatry patients’ treatment and care, has many benefits, such as minimizing the sequence of going to hospital. The community mental health nurse, who works as an incidence manager, takes on the responsibility of treatment and care of the patient in the place where he/she lives, and the directly protective effect of this responsibility is an unquestionable fact. With this practice, the process of taking cure in hospital and the cost of treatment and care decrease. In our country, this sub-field of psychiatry is still in its incipient stage. Being familiar with the successful model practices in different countries may constitute a good model for the community mental health nursing practices which are on the first level in our country. For this purpose, the role of the nurses who work for the community mental health service in England is presented in this study.

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

Science.gov (United States)

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.

Exploring Partnerships between Local Communities and Timber Companies: An Experiment Using the Role-Playing Games Approach

Directory of Open Access Journals (Sweden)

Herry Purnomo

2009-01-01

Full Text Available Cooperation among stakeholders is widely accepted as an effective management strategy. This paper describes an experimental study that explores this cooperation using role-playing games, which is formulated within a multiagent simulation framework. This framework enables participants to take active roles in mimicking the collaborative decision environment and the behaviors and attitudes of the different stakeholders. The paper examines a forest plantation company in South Sumatra, Indonesia, which has cooperated with local communities since 2000. The experimental pilot study described in this paper explored the role of communication in partnership relationships between the company and the local communities living within and around the surroundings of the company's plantation. These partnerships were explored and analyzed using the gaming approach involving university students taking the role of forest stakeholders, from both the timber company and the local communities. Lessons learned from the game provided the rationale for the establishment of a communication institution called “Forum Sebahu Sejalan.” This formal forum was constituted after a facilitated ex-postinteraction between representatives from the timber company and local communities. Results and observations drawn from the interactions show the potentials of the RPG approach and the formal forum in crafting resilient partnerships among stakeholders.

2008-07-01

Evaluations of Community Health Worker programs consistently document improvements in health, yet few articles clearly describe the roles of Community Health Workers (CHWs) from the CHWs' perspective. This article presents the CHWs' points of view regarding the various roles they played in a community-based participatory research (CBPR) project, Poder es Salud/Power for Health in Portland, Oregon, including their roles as community organizers and co-researchers. Authors draw from an analysis of transcript data from in-depth interviews conducted with CHWs to present a description of the strategies employed by the CHWs to build leadership skills and knowledge among community members. CHWs also discuss their own personal and professional development. The analysis of the interviews suggests that CHWs valued their multiple roles with Poder es Salud/Power for Health and their participation on the project's Steering Committee. Based on CHWs' descriptions of their work, this type of involvement appears to build the CHWs' leadership skills and sense of efficacy to create change in their communities. By serving as community organizers and participating as producers of research, rather than acting merely as a deliverer of the intervention activities, the CHWs were able to build skills that make them more successful as CHWs.

Role of Knowledge Based Communities in Knowledge Process

Sebastian Ion CEPTUREANU

2015-12-01

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.

The National Aeronautics and Space Administration Biological Specimen Repository (Repository) is a storage bank that is used to maintain biological specimens over extended periods of time and under well-controlled conditions. Samples from the International Space Station (ISS), including blood and urine, will be collected, processed and archived during the preflight, inflight and postflight phases of ISS missions. This investigation has been developed to archive biosamples for use as a resource for future space flight related research. The International Space Station (ISS) provides a platform to investigate the effects of microgravity on human physiology prior to lunar and exploration class missions. The storage of crewmember samples from many different ISS flights in a single repository will be a valuable resource with which researchers can study space flight related changes and investigate physiological markers. The development of the National Aeronautics and Space Administration Biological Specimen Repository will allow for the collection, processing, storage, maintenance, and ethical distribution of biosamples to meet goals of scientific and programmatic relevance to the space program. Archiving of the biosamples will provide future research opportunities including investigating patterns of physiological changes, analysis of components unknown at this time or analyses performed by new methodologies.

Community nurses' child protection role: views of public health nurses in Ireland.

LENUS (Irish Health Repository)

Kent, Susan

2011-11-01

Public health nurses in Ireland are generalist practitioners with a wide range of roles that address the needs of clients in the community across their lifespan. Child protection is one of many of the roles of Irish public health nurses. However, with increasing caseloads, birth rates and aging populations, their child protection role is becoming more difficult to define and practise safely. This paper presents a key finding of a qualitative study that explored the views of a group of public health nurses (n = 10) regarding their role with pre-school children. A significant theme following analysis of the interviews were the nurses\\' expressed concerns on their role in child protection. There is a need to define the role practised by public health nurses in child protection and to achieve a standard for this nationally.

What is the role of community capabilities for maternal health? An exploration of community capabilities as determinants to institutional deliveries in Bangladesh, India, and Uganda

Directory of Open Access Journals (Sweden)

Ligia Paina

2016-11-01

Full Text Available Abstract Background While community capabilities are recognized as important factors in developing resilient health systems and communities, appropriate metrics for these have not yet been developed. Furthermore, the role of community capabilities on access to maternal health services has been underexplored. In this paper, we summarize the development of a community capability score based on the Future Health System (FHS project’s experience in Bangladesh, India, and Uganda, and, examine the role of community capabilities as determinants of institutional delivery in these three contexts. Methods We developed a community capability score using a pooled dataset containing cross-sectional household survey data from Bangladesh, India, and Uganda. Our main outcome of interest was whether the woman delivered in an institution. Our predictor variables included the community capability score, as well as a series of previously identified determinants of maternal health. We calculate both population-averaged effects (using GEE logistic regression, as well as sub-national level effects (using a mixed effects model. Results Our final sample for analysis included 2775 women, of which 1238 were from Bangladesh, 1199 from India, and 338 from Uganda. We found that individual-level determinants of institutional deliveries, such as maternal education, parity, and ante-natal care access were significant in our analysis and had a strong impact on a woman’s odds of delivering in an institution. We also found that, in addition to individual-level determinants, greater community capability was significantly associated with higher odds of institutional delivery. For every additional capability, the odds of institutional delivery would increase by up to almost 6 %. Conclusion Individual-level characteristics are strong determinants of whether a woman delivered in an institution. However, we found that community capability also plays an important role, and should be

This study explores the experiences of family members in supporting community re-integration and return to productive occupations of the traumatic brain injury (TBI) survivor in order to: (i) describe family members' supportive roles, (ii) determine challenges family members experience in supporting the TBI survivor; and (iii) identify supports that family members require to maintain and enhance their roles. This qualitative descriptive study involved 14 interviews with immediate family members of TBI survivors. Data was analyzed using thematic analysis. Family members expressed strong motivation and engaged in six key roles to support TBI survivors: researcher, case manager, advocate, coach, activities of daily living (ADL)/instrumental ADLs and emotional supporter. Personal and family stressors and challenges navigating the health care system were perceived as challenges in meeting demands of their supportive roles. Stigma also presented a barrier to successful community and vocational re-integration. Subsequently, family members desired more education related to the functional implications of TBI, to be connected to health care and community resources, and sought a greater family-centred care approach. Family members require on-going counseling and community supports to prevent burnout and allow for their continued engagement in their supportive roles. Further education on how to navigate the health care system, access community programs and rights to workplace accommodation is also warranted. Family members are strongly motivated to support survivors' return to productive occupation following a traumatic brain injury, but require counseling and community support to enable their on-going engagement and prevent burnout. Family members can be further empowered through the implementation of family-centred care. Family members requested further education on the long-term functional implications of TBI, how to navigate the health care system, how to access community

This paper examines lay interpretations of lay health worker roles within three UK community-based health promotion projects. It argues that understanding lay health worker roles requires critical analysis of the complex interrelationships between professionals, lay workers and the communities receiving a programme. Findings are presented that are drawn from a qualitative study of lay engagement in public health programme delivery where a key objective was to examine the perspectives of community members with the experience of receiving services delivered by lay health workers. Interviews and focus groups were conducted with 46 programme recipients from three case study projects; a breastfeeding peer support service, a walking for health scheme and a neighbourhood health project. The results show how participants interpreted the function and responsibilities of lay health workers and how those roles provided personalized support and facilitated engagement in group activities. Further insights into community participation processes are provided revealing the potential for active engagement in both formal and informal roles. The paper concludes that social relationships are core to understanding lay health worker programmes and therefore analysis needs to take account of the capacity for community members to move within a spectrum of participation defined by increasing responsibility for others.

Wilson, Jeffrey D.; Kerczewski, Robert J.

2011-01-01

The next generation of aeronautical communications for airport surface applications has been identified through a NASA research program and an international collaborative future communications study. The result, endorsed by both the United States and European regulatory agencies is called AeroMACS (Aeronautical Mobile Airport Communications System) and is based upon the IEEE 802.16e mobile wireless standard. Coordinated efforts to develop appropriate aviation standards for the AeroMACS system are now underway within RTCA (United States) and Eurocae (Europe). AeroMACS will be implemented in a recently allocated frequency band, 5091-5150 MHz. As this band is also occupied by fixed satellite service uplinks, AeroMACS must be designed to avoid interference with this incumbent service. The aspects of AeroMACS operation that present potential interference to the fixed satellite service are under analysis in order to enable the definition of standards that assure that such interference will be avoided. The NASA Glenn Research Center has been involved in this analysis, and the first results of modeling and simulation efforts directed at this analysis are the subject of this presentation.

A heuristic framework for understanding the role of participatory decision making in community-based non-profits.

Science.gov (United States)

Bess, Kimberly D; Perkins, Douglas D; Cooper, Daniel G; Jones, Diana L

2011-06-01

This paper explores the role of member participation in decision-making (PDM) from an organizational learning (OL) perspective. Community-based organizations (CBOs) serve as mediators between the individual and the local community, often providing the means for community member participation and benefiting organizationally from members' input. Community psychologists have recognized these benefits; however, the field has paid less attention to the role participation plays in increasing CBOs' capacity to meet community needs. We present a framework for exploring how CBO contextual factors influence the use of participatory decision-making structures and practices, and how these affect OL. We then use the framework to examine PDM in qualitative case study analysis of four CBOs: a youth development organization, a faith-based social action coalition, a low-income neighborhood organization, and a large human service agency. We found that organizational form, energy, and culture each had a differential impact on participation in decision making within CBOs. We highlight how OL is constrained in CBOs and document how civic aims and voluntary membership enhanced participation and learning.

2014-01-01

In support of NASAs ongoing effort to bring supersonic commercial travel to the public, NASA Dryden Flight Research Center and NASA Langley Research Center, in cooperation with other industry organizations, conducted a flight research experiment to identify the methods, tools, and best practices for a large-scale quiet (or low) sonic boom community human response test. The name of the effort was Waveforms and Sonic boom Perception and Response. Such tests will go towards building a dataset that governing agencies like the Federal Aviation Administration and International Civil Aviation Organization will use to establish regulations for acceptable sound levels of overland sonic booms. Until WSPR, there had never been an effort that studied the response of people in their own homes and performing daily activities to non-traditional, low sonic booms.WSPR was a NASA collaborative effort with several industry partners, in response to a NASA Aeronautics Research Mission Directorate Research Opportunities in Aeronautics. The primary contractor was Wyle. Other partners included Gulfstream Aerospace Corporation, Pennsylvania State University, Tetra Tech, and Fidell Associates, Inc.A major objective of the effort included exposing a community with the sonic boom magnitudes and occurrences expected in high-air traffic regions with a network of supersonic commercial aircraft in place. Low-level sonic booms designed to simulate those produced by the next generation of commercial supersonic aircraft were generated over a small residential community. The sonic boom footprint was recorded with an autonomous wireless microphone array that spanned the entire community. Human response data was collected using multiple survey methods. The research focused on essential elements of community response testing including subject recruitment, survey methods, instrumentation systems, flight planning and operations, and data analysis methods.This paper focuses on NASAs role in the efforts

ROLES OF COMMUNITIES OF PRACTICE FOR THE DEVELOPMENT OF THE SOCIETY

Directory of Open Access Journals (Sweden)

Haradhan Kumar MOHAJAN

2017-10-01

Full Text Available At present one of the most important concepts in social learning theory is the idea of communities of practice (CoP, which describes a learning theory with a strong relationship to the social construction of knowledge. A CoP is a collection of people who engage on performing a common activity for the welfare both of members of the community and the society. In modern society, it is used in some form of high levels of skills, knowledge and proficiency to perform the jobs properly. It plays an important role in the sharing of knowledge and creating value for both their members and organizations. A CoP is composed of three crucial characteristics: domain, community, and practice, which provide a guide to the development of community. The paper describes structural components, basic characteristics, and essential elements of a CoP. It also highlights benefits, importance, and the challenges and barriers of a CoP. In addition, it describes virtual CoP in brief. The main aim of this study is to explore the ins and out of a CoP in some details

Burchell, Kevin; Rettie, Ruth; Roberts, Tom C.

2016-01-01

The provision of energy consumption feedback on in-home displays (IHDs) has a prominent role in government strategies for domestic energy demand reduction. Research suggests that IHDs can support energy consumption reduction, but also that engagement with IHDs can be limited to men and is often short-term. In this paper, we draw on research carried out in Smart Communities, a two-year project in which electricity and gas consumption feedback played a key role. This study was distinctive because it was accompanied by a weekly email communications programme and was provided within the context of community action. Project findings suggest that, although by no means panaceas, approaches such as these can support long-term engagement with energy consumption feedback, including by women, and can support behaviour change. - Highlights: • We examine the challenge of householder engagement with energy consumption feedback. • The potential of ‘community action’ and ‘communications’ is explored. • These approaches are shown to support long-term engagement by householders. • These approaches are also shown to support greater engagement by women. • Recommendations for future IHD platforms and smart meter roll-outs are presented.

Directionality is a crucial ingredient in many complex networks in which information, energy or influence are transmitted. In such directed networks, analysing flows (and not only the strength of connections) is crucial to reveal important features of the network that might go undetected if the orientation of connections is ignored. We showcase here a flow-based approach for community detection through the study of the network of the most influential Twitter users during the 2011 riots in England. Firstly, we use directed Markov Stability to extract descriptions of the network at different levels of coarseness in terms of interest communities, i.e. groups of nodes within which flows of information are contained and reinforced. Such interest communities reveal user groupings according to location, profession, employer and topic. The study of flows also allows us to generate an interest distance, which affords a personalized view of the attention in the network as viewed from the vantage point of any given user. Secondly, we analyse the profiles of incoming and outgoing long-range flows with a combined approach of role-based similarity and the novel relaxed minimum spanning tree algorithm to reveal that the users in the network can be classified into five roles. These flow roles go beyond the standard leader/follower dichotomy and differ from classifications based on regular/structural equivalence. We then show that the interest communities fall into distinct informational organigrams characterized by a different mix of user roles reflecting the quality of dialogue within them. Our generic framework can be used to provide insight into how flows are generated, distributed, preserved and consumed in directed networks.

Cross-Cultural “Allies” in Immigrant Community Practice: Roles of foreign-trained former Montagnard health professionals

2014-05-01

Full Text Available This pilot case study describes foreign-trained former Montagnard refugee physicians’ practice experiences in Vietnam and their current community health worker and “ally” roles within the Montagnard refugee community. It highlights key features that facilitate cross-culturally responsive health care. We interviewed five Vietnam-trained former Montagnard refugee physicians using an open-ended interview format during March, 2012. We used content analysis procedures to identify key themes characterizing Montagnard physicians’ former and current practice experiences and emphasizing the roles they currently play in their new homeland. Montagnard physicians were fighting infectious diseases in homeland Vietnamese communities. Since coming to the U.S., Montagnard physicians have reoriented their competencies to fit within a community health workers model, and have shifted practice to fighting chronic disease in this refugee community. Tasks now include describing and contextualizing unique characteristics of the Montagnard languages and cultures to outside constituents. They become cross-cultural allies to the U.S. health care and facilitate individuals’ medical adherence with mainstream physicians’ orders. They ensure accuracy of interpretation of Montagnard patients’ medical complaints during a medical visit. Our findings reveal the potential roles that can be ascribed to a cross-cultural ally and can be built into practice to fulfill the Montagnard community’s unmet health needs: oral historian, mediator, facilitator/negotiator, quality assurer, psychosocial confidant, and health advocate.

Gidman, Wendy; Cowley, Joseph

2013-10-01

To understand members of the public's opinions and experiences of pharmacy services. This exploratory study employed qualitative methods. Five focus groups were conducted with 26 members of the public resident in Scotland in March 2010. The groups comprised those perceived to be users and non-users of community pharmacy. A topic guide was developed to prompt discussion. Each focus group was recorded, transcribed, anonymised and analysed using thematic analysis. Participants made positive comments about pharmacy services although many preferred to see a general practitioner (GP). Participants discussed using pharmacies for convenience, often because they were unable to access GPs. Pharmacists were perceived principally to be suppliers of medicine, although there was some recognition of roles in dealing with minor ailments and providing advice. For those with serious and long-standing health matters GPs were usually the professional of choice for most health needs. Community pharmacy was seen to offer incomplete services which did not co-ordinate well with other primary-care services. The pharmacy environment and retail setting were not considered to be ideal for private healthcare consultations. This study suggests that despite recent initiatives to extend the role of community pharmacists many members of the general public continue to prefer a GP-led service. Importantly GPs inspire public confidence as well as offering comprehensive services and private consultation facilities. Improved communication and information sharing between community pharmacists and general practice could support community pharmacist-role expansion. © 2012 The Authors.

The role of social engagement and identity in community mobility among older adults aging in place.

Science.gov (United States)

Gardner, Paula

2014-01-01

The purpose of this study was to understand how neighbourhoods - as physical and social environments - influence community mobility. Seeking an insider's perspective, the study employed an ethnographic research design. Immersed within the daily lives of 6 older adults over an 8-month period, auditory, textual, and visual data was collected using the "go-along" interview method. During these interviews, the researcher accompanied participants on their natural outings while actively exploring their physical and social practices by asking questions, listening, and observing. Findings highlight a process of community mobility that is complex, dynamic and often difficult as participant's ability and willingness to journey into their neighborhoods were challenged by a myriad of individual and environmental factors that changed from one day to the next. Concerned in particular with the social environment, final analysis reveals how key social factors - social engagement and identity - play a critical role in the community mobility of older adults aging in place. Identity and social engagement are important social factors that play a role in community mobility. The need for social engagement and the preservation of identity are such strong motivators for community mobility that they can "trump" poor health, pain, functional ability and hazardous conditions. To effectively promote community mobility, the social lives and needs of individuals must be addressed.

Delivery with skilled birth attendants is important for reducing maternal mortality in developing countries. However, traditional birth attendants (TBAs) are abundant in such settings, managing deliveries without the skills and resources necessary to prevent mortality in this situations. Interventions that have been proposed to mitigate the situation include redefining the role of TBAs to nutrition advocates and birth companions for pregnant women to health facilities. We thus explored community perceptions on these new roles of TBAs, as birth companions and nutrition advocates, and their influence on health facility deliveries in Kakamega County, Kenya. Qualitative data was collected through key informant interviews with health workers and focus group discussions with lactating mothers, pregnant women, husbands, community leaders, community health volunteers, and TBA. Content analysis was conducted; data was organized into subthemes and conclusions made from each subtheme using Atlas.ti software. TBAs adopted their birth companion role as the majority offered companionship to mothers delivering at health facilities. Mothers were happy with this role as TBAs continued providing companionship even after delivery. The community members were happy with the new role of TBAs and reported increased deliveries at the health facilities. In contrast, TBAs did not adopt the nutrition advocacy role sufficiently. We found that redefining the role of the TBAs into birth companions to support facility-based delivery is thus feasible and acceptable. Nutrition advocacy by the TBAs should be strengthened to maximize on the opportunity provided by the close association between TBAs and mothers and the community. © 2018 John Wiley & Sons Ltd.

The training is designed to help participants reflect on their identity as a role model and provide research-based strategies to effectively engage youth, particularly girls, in STEM (science, technology, engineering, and mathematics). Research shows that even though girls and boys do not demonstrate a significant difference in their ability to be successful in mathematics and science, there is a significant difference in their confidence level when participating in STEM subject matter and pursuing STEM careers. The Langley training model prepares professionals to disrupt this pattern and take on the habits and skills of effective role models. The training model is based on other successful models and resources for role modeling in STEM including SciGirls; the National Girls Collaborative; and publications by the American Association of University Women and the National Academies. It includes a significant reflection component, and participants walk through situation-based scenarios to practice a focused suite of research-based strategies. These strategies can be implemented in a variety of situations and adapted to the needs of groups that are underrepresented in STEM fields. Underpinning the training and the discussions is the fostering of a growth mindset and promoting perseverance. "The Power of Yet" becomes a means whereby role models encourage students to believe in themselves, working toward reaching their goals and dreams in the area of STEM. To provide additional support, NASA Langley role model trainers are available to work with a champion at other organizations to facilitate the training. This champion helps recruit participants, seeks leadership buy-in, and helps provide valuable insights for needs and

2017-01-01

Full Text Available Background: Obesity and poor health habits impact youth’s health and occupational participation. Occupational therapy’s role in preventing and treating obesity continues to emerge in the research literature. This article explores the impact of a community-based program emphasizing health and wellness for female youth. Methods: Five girls 11 to 13 years of age participated in the healthy occupations program. Before and after the program, the participants engaged in an individual semi-structured interview and completed the Canadian Occupational Performance Measure and the CATCH Kids Club Questionnaire. The youth participated in a focus group midprogram. Results: The participants were receptive to information regarding healthy behaviors and initiated positive health behavior changes after implementation of a 7-week healthy lifestyle community- based program. Conclusion: Occupational therapy can collaborate with community partners to provide programming focused on health promotion and prevention as part of the interprofessional approach to preventing and treating childhood obesity and building healthier communities.

This study explored the experiences and views of individuals with type 2 diabetes mellitus (T2D) on their diabetes self-management and potential roles for community pharmacists in diabetes self-management education and support (DSME/S) in Malaysia. A qualitative study, using semi-structured, face-to-face interviews, was conducted with patients with T2D attending a primary care health clinic in Kuala Lumpur, Malaysia. The interviews were audio-recorded, transcribed verbatim and analysed inductively. Fourteen participants with T2D were interviewed. Data were coded into five main themes: experience and perception of diabetes self-management, constraints of the current healthcare system, perception of the community pharmacist and community pharmacies, perceived roles for community pharmacists in diabetes care, and challenges in utilising community pharmacies to provide DSME/S. There were misconceptions about diabetes management that may be attributed to a lack of knowledge. Although participants described potential roles for community pharmacists in education, medication review and continuity of care, these roles were mostly non-clinically oriented. Participants were not confident about community pharmacists making recommendations and changes to the prescribed treatment regimens. While participants recognised the advantages of convenience of a community pharmacy-based diabetes care service, they raised concerns over the retail nature and the community pharmacy environment for providing such services. This study highlighted the need to improve the care provision for people with T2D. Participants with T2D identified potential, but limited roles for community pharmacists in diabetes care. Participants expressed concerns that need to be addressed if effective diabetes care is to be provided from community pharmacies in Malaysia. © 2017 Royal Pharmaceutical Society.

Full Text Available Lorenzo Aguilar1, María-José Giménez1, José Barberán21Microbiology Department, School of Medicine, University Complutense, Madrid; 2Infectious Diseases Department, Hospital Central de la Defensa Gomez Ulla, Madrid, SpainAbstract: The nasopharynx is the ecological niche where evolution towards resistance occurs in respiratory tract isolates. Dynamics of different bacterial populations in antibiotic-free multibacterial niches are the baseline that antibiotic treatments can alter by shifting the competitive balance in favor of resistant populations. For this reason, antibiotic resistance is increasingly being considered to be an ecological problem. Traditionally, resistance has implied the need for development of new antibiotics for which basic efficacy and safety data are required prior to licensing. Antibiotic development is mainly focused on demonstrating clinical efficacy and setting susceptibility breakpoints for efficacy prediction. However, additional information on pharmacodynamic data predicting absence of selection of resistance and of resistant subpopulations, and specific surveillance on resistance to core antibiotics (to detect emerging resistances and its link with antibiotic consumption in the community are valuable data in defining the role of a new antibiotic, not only from the perspective of its therapeutic potential but also from the ecologic perspective (countering resistances to core antibiotics in the community. The documented information on cefditoren gleaned from published studies in recent years is an example of the role for an emerging oral antibacterial facing current antibiotic resistance in community-acquired respiratory tract infections.Keywords: respiratory tract infection, antibiotic resistance, cefditoren, community

Role of computation fluid dynamics in aeronautical engineering (4). Development and applications of implicit TVD finete volume code

Energy Technology Data Exchange (ETDEWEB)

Shima, Eiji; Jounouchi, Tadamasa

1986-12-01

Potential analysis in aeronautic design has reached the stage of practical use although it involves problems concerning accuracy and restrictions on its application. On the other hand, numerical analysis using Euler and Navier-Stokes (N-S) equations is based on a highly accurate theory, so is preferable, but has not reached the stage of practical use because it involves problems that shapes that can be analyzed are restricted on account of factors relating to computation lattice generation and because it involves difficulty relating to computation time. The essential factor in numerical analysis is stoutness (numeric stability). From this viewpoint, an Euler/N-S method was developed; the theory begins with TVD finite volume code, and incorporates various types of improvement to raise accuracy and shorten computation time; hence, it satisfies design requirements. The use of this method helps get solution under a wide range of flow condition without any fine adjustments, such as artificial viscosity. (6 figs, 1 tab, 10 refs)

. Community based participatory research (CBPR) is often initiated by academic researchers, yet relies on meaningful community engagement and ownership to have lasting impact. Little is understood about how ownership shifts from academic to community partners. . We examined a CBPR project over its life course and asked: what does the evolution of ownership look like from project initiation by an academic (non-community) champion (T1); to maturation-when the intervention is ready to be deployed (T2); to independence-the time when the original champion steps aside (T3); and finally, to its maintenance-when the community has had an opportunity to function independently of the original academic champion (T4)? . Using sociometric (whole network) social network analysis, knowledge leadership was measured using 'in-degree centrality'. Stakeholder network structure was measured using 'centralisation' and 'core-periphery analysis'. Friedman rank sum test was used to measure change in actor roles over time from T1 to T4. . Project stakeholder roles were observed to shift significantly (P project maintenance (T4). Community stakeholders emerged into positions of knowledge leadership, while the roles of academic partners diminished in importance. The overall stakeholder network demonstrated a structural shift towards a core of densely interacting community stakeholders. . This was the first study to use Social network analysis to document a shift in ownership from academic to community partners, indicating community self-determination over the research process. Further analysis of qualitative data will determine which participatory actions or strategies were responsible for this observed change. © The Author 2017. Published by Oxford University Press.

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.

ICAO Aeronautical chart production: aerodrome obstruction charts from small–format aerial digital imagery

Directory of Open Access Journals (Sweden)

Jorge Padro Molina

2012-11-01

Full Text Available Aeronautical charts and aerodrome obstruction charts, provide information about obstacles around the airport, so pilots and air traffic controllers can comply with the procedures and limitations of its utilization. Safety in aviation demands updated and precise aeronautical charts production, adopting the standards of the International Civil Aviation Organization (ICAO. In this paper the methodology employed to generate obstruction charts for five airports in Mexico, using aerial digital imagery obtained with small–format cameras, is described. Through two aerial surveys on each airport, from 10 000 and 5 000 feet above ground level, two orthomosaics were generated covering the airport influence area, the runway, and the obstacle limitation surfaces: approach/Take–off climb, transitional, inner horizontal, and conical. Using stereopair photointerpretation most of the obstacles were identified, and by means of the orthomosaics; aerodrome charts, and aerodrome obstruction charts types A, B and C, were generated. Using satellite geodetic receivers, 18 points were surveyed on each runway in order to obtain its dimensions, and to establish ground control points for mosaics generation. Throughout detailed field work, height and location of the obstacles were verified, and finally, after several reviewing processes by aeronautical authorities, generation of ICAO charts was concluded when all airport maps were integrated in a Geographical Information System.

Volodymyr Kharchenko

2016-06-01

Full Text Available The aim of this study is to investigate the influence of Rician fading on messages transmission via the aeronautical satellite OFDM channel with adaptive modulation and the development of a method for estimating the parameters of such a channel. Methods: To study the effect of Rician fading on messages transmission via aeronautical satellite OFDM channel with adaptive modulation the original model of the communication channel “Aircraft-Satellite-Ground Station” was built using software package MATLAB Sіmulіnk. The model includes “Aircraft Transmitter”, “Uplink/Downlink Path”, “Satellite Transponder”, and “Ground Station Receiver”. Each modulator block in the modulation bank performs convolutional coding and puncturing using code rates of ½, ²/3, and ¾, data interleaving, BPSK, QPSK, 16-QAM, and 64-QAM modulation. Results: Dependences of Estimated channel SNR on the ratio between the power of the LOS component and the diffuse component, on the downlink gain and delay in the diffuse component for different Doppler spectrum types and Doppler frequency offsets were obtained. A method for estimating the parameters of the satellite channels with fading was proposed. Discussion: The realistic model of aeronautical satellite OFDM link with Rician fading is developed for the first time on a basis of IEEE 802.11a standard and used for channel parameters evaluation. Proposed in this article approach can be considered as a method for estimating parameters of the channel with fading.

The relative role of dispersal and local interactions for alpine plant community diversity under simulated climate warming

Most studies on factors determining diversity are conducted in temperate or warm regions, whereas studies in climatically harsh and low productivity areas, such as alpine regions, are rare. We examined the relative roles of seed availability and different biotic and abiotic factors for the diversity of an alpine plant community in southern Norway. Furthermore, because climate warming is predicted to be an important driver of alpine species diversity, we assessed how the relative impacts of dispersal and local interactions on diversity might change under experimental warming (open top chambers, OTCs). Addition of seeds from 27 regional species increased community diversity. The establishment of the species was negatively related both to the diversity of the existing system and the cover of the abundant dwarf shrub Dryas octopetala. These results show that both species dispersal limitation and local biotic interactions are important factors for alpine plant community diversity. Despite relatively harsh environmental conditions and low productivity, competition from the resident vegetation appeared to have a greater role for species establishment and diversity than facilitation and experimental warming. Higher temperature appeared to increase the negative relationship between resident species diversity and species establishment. This may suggest that climate warming can increase the role of interspecific competition for alpine plant community structure, and thus alter the long-term effects of biotic interactions on diversity.

The links between gender roles, gender-based violence and HIV/AIDS risk are complex and culturally specific. In this qualitative study we investigated how women and men in two black communities in the Western Cape, South Africa, constructed their gender identities and roles, how they understood gender-based violence, and what they believed about the links between gender relations and HIV risk. First we conducted 16 key informant interviews with members of relevant stakeholder organisations. Then we held eight focus group discussions with community members in single-sex groups. Key findings included the perception that although traditional gender roles were still very much in evidence, shifts in power between men and women were occurring. Also, gender-based violence was regarded as a major problem throughout communities, and was seen to be fuelled by unemployment, poverty and alcohol abuse. HIV/AIDS was regarded as particularly a problem of African communities, with strong themes of stigma, discrimination, and especially 'othering' evident. Developing effective HIV/AIDS interventions in these communities will require tackling the overlapping as well as divergent constructions of gender, gender violence and HIV which emerged in the study.

A Constructive Reframing of Student Roles and Systems Learning in Medical Education Using a Communities of Practice Lens.

2017-12-01

Health systems are in the midst of a transformation that is being driven by a variety of forces. This has important implications for medical educators because clinical practice environments play a key role in learning and professional development, and evolving health systems are beginning to demand that providers have "systems-ready" knowledge, attitudes, and skills. Such implications provide a clear mandate for medical schools to modify their goals and prepare physicians to practice flexibly within teams and effectively contribute to the improvement of health care delivery. In this context, the concepts of value-added medical education, authentic student roles, and health systems science are emerging as increasingly important. In this Article, the authors use a lens informed by communities of practice theory to explore these three concepts, examining the implications that the communities of practice theory has in the constructive reframing of educational practices-particularly common student roles and experiences-and charting future directions for medical education that better align with the needs of the health care system. The authors apply several key features of the communities of practice theory to current experiential roles for students, then propose a new approach to students' clinical experiences-value-added clinical systems learning roles-that provides students with opportunities to make meaningful contributions to patient care while learning health systems science at the patient and population level. Finally, the authors discuss implications for professional role formation and anticipated challenges to the design and implementation of value-added clinical systems learning roles.

Robust Timing Synchronization in Aeronautical Mobile Communication Systems

Science.gov (United States)

Xiong, Fu-Qin; Pinchak, Stanley

2004-01-01

This work details a study of robust synchronization schemes suitable for satellite to mobile aeronautical applications. A new scheme, the Modified Sliding Window Synchronizer (MSWS), is devised and compared with existing schemes, including the traditional Early-Late Gate Synchronizer (ELGS), the Gardner Zero-Crossing Detector (GZCD), and the Sliding Window Synchronizer (SWS). Performance of the synchronization schemes is evaluated by a set of metrics that indicate performance in digital communications systems. The metrics are convergence time, mean square phase error (or root mean-square phase error), lowest SNR for locking, initial frequency offset performance, midstream frequency offset performance, and system complexity. The performance of the synchronizers is evaluated by means of Matlab simulation models. A simulation platform is devised to model the satellite to mobile aeronautical channel, consisting of a Quadrature Phase Shift Keying modulator, an additive white Gaussian noise channel, and a demodulator front end. Simulation results show that the MSWS provides the most robust performance at the cost of system complexity. The GZCD provides a good tradeoff between robustness and system complexity for communication systems that require high symbol rates or low overall system costs. The ELGS has a high system complexity despite its average performance. Overall, the SWS, originally designed for multi-carrier systems, performs very poorly in single-carrier communications systems. Table 5.1 in Section 5 provides a ranking of each of the synchronization schemes in terms of the metrics set forth in Section 4.1. Details of comparison are given in Section 5. Based on the results presented in Table 5, it is safe to say that the most robust synchronization scheme examined in this work is the high-sample-rate Modified Sliding Window Synchronizer. A close second is its low-sample-rate cousin. The tradeoff between complexity and lowest mean-square phase error determines

Aeronautics Autonomy Testbed Capability (AATC) Team Developed Concepts

Smith, Phillip J.

2018-01-01

In 2015, the National Aeronautics and Space Administration (NASA) formed a multi-center, interdisciplinary team of engineers from three different aeronautics research centers who were tasked with improving NASA autonomy research capabilities. This group was subsequently named the Aeronautics Autonomy Testbed Capability (AATC) team. To aid in confronting the autonomy research directive, NASA contracted IDEO, a design firm, to provide consultants and guides to educate NASA engineers through the practice of design thinking, which is an unconventional method for aerospace design processes. The team then began learning about autonomy research challenges by conducting interviews with a diverse group of researchers and pilots, military personnel and civilians, experts and amateurs. Part of this design thinking process involved developing ideas for products or programs known as concepts that could enable real world fulfillment of the most important latent needs identified through analysis of the interviews. The concepts are intended to be sacrificial, intermediate steps in the design thinking process and are presented in this report to record the efforts of the AATC group. Descriptions are provided in present tense to allow for further ideation and imagining the concept as reality as was attempted during the teams discussions and interviews. This does not indicate that the concepts are actually in practice within NASA though there may be similar existing programs independent of AATC. These concepts were primarily created at two distinct stages during the design thinking process. After the initial interviews, there was a workshop for concept development and the resulting ideas are shown in this work as from the First Round. As part of succeeding interviews, the team members presented the First Round concepts to refine the understanding of existing research needs. This knowledge was then used to generate an additional set of concepts denoted as the Second Round. Some

Full Text Available In an era when Haemophilus influenzae type b (Hib conjugate vaccine is widely used, the incidence of Hib as a cause of community-acquired pneumonia (CAP has dramatically declined. Non-typeable H. influenzae (NTHi strains and, occasionally, other encapsulated serotypes of H. influenzae are now the cause of the majority of invasive H. influenzae infections, including bacteraemic CAP. NTHi have long been recognised as an important cause of lower respiratory tract infection, including pneumonia, in adults, especially those with underlying diseases. The role of NTHi as a cause of non-bacteraemic CAP in children is less clear. In this review the evidence for the role of NTHi and capsulated strains of H. influenzae will be examined.

Friction Stir Welding (FSW) is an innovative solid-state joining process. This process was, in first time, develop to join the similar aluminum plates but now the technology can be used to weld a large area of materials similar or dissimilar. Taking these into account FSW process, for dissimilar materials are increasingly required, more than traditional arc welding, in industrial environment. More than that FSW is used in aeronautics industry because of very good result and very good weldability between aluminum alloy used at building of airplanes, where the body of airplane are 20% aluminum alloy and this percent can be increaser in future. In this paper is presented an experimental study which includes welding three dissimilar aluminum alloy, with different properties, used in aeronautics industry, this materials are: AA 2024, AA6061 and AA7075. After welding with different parameters, the welding join and welding process will be analyzed considering process temperature, process vertical force, and roughnessof welding seams, visual aspect and microhardness.

Evolutionary optimization and game strategies for advanced multi-disciplinary design applications to aeronautics and UAV design

CERN Document Server

Periaux, Jacques; Lee, Dong Seop Chris

2015-01-01

Many complex aeronautical design problems can be formulated with efficient multi-objective evolutionary optimization methods and game strategies. This book describes the role of advanced innovative evolution tools in the solution, or the set of solutions of single or multi disciplinary optimization. These tools use the concept of multi-population, asynchronous parallelization and hierarchical topology which allows different models including precise, intermediate and approximate models with each node belonging to the different hierarchical layer handled by a different Evolutionary Algorithm. The efficiency of evolutionary algorithms for both single and multi-objective optimization problems are significantly improved by the coupling of EAs with games and in particular by a new dynamic methodology named “Hybridized Nash-Pareto games”. Multi objective Optimization techniques and robust design problems taking into account uncertainties are introduced and explained in detail. Several applications dealing with c...

2017-08-01

Community coalitions have proliferated as a means of addressing a range of complex community problems. Such coalitions often consist of a small paid staff and volunteer members. The present study examines one likely contributor to coalition effectiveness: the degree of agreement on role expectations between paid staff and volunteer members. Role confusion occurs when paid staff and volunteers differ in their expectations of who is responsible for accomplishing specific tasks. Staff and volunteer members from 69 randomly selected Drug Free Coalitions in the United States as well as 21 Drug Free Coalitions in Connecticut were asked to respond to an online survey asking about 37 specific coalition tasks critical for effective coalition functioning and the degree to which paid staff and/or voluntary members should be responsible for accomplishing each. Our final sample consisted of 476 individuals from 35 coalitions. Using coalitions as the unit of analysis, we found significant differences between paid staff and volunteer coalition members on nine tasks reflecting four domains: meeting leadership and participation, (2) planning and implementation leadership, (3) publicity/media relations, and (4) logistical functions. Implications of these differences and ways that evaluators could help coalitions deal with differing role expectations were discussed. Copyright © 2017 Elsevier Ltd. All rights reserved.

It provides a means to evaluate the impact of modified router scheduling algorithms on the network efficiency, to perform capacity studies on various network topologies and to monitor and study various aspects of ATN through graphical user interface (GUI). In this paper we describe briefly about the proposed ATN model and our abstraction of this model. Later we describe our simulator architecture highlighting some of the design specifications, scheduling algorithms and user interface. At the end, we have provided the results of performance studies on this simulator.

Gout is an increasingly prevalent form of inflammatory arthritis. Although effective treatments for gout exist, current management is suboptimal due to low medication adherence rates and treatments that are non-concordant with guidelines. Medications are the mainstay and most effective form of gout management. Thus, there is potential for community pharmacists to play an important primary health care role in gout management, however their current role and their potential to improve management of gout treatment is currently unclear. The purpose of the study is to explore the views of Australian pharmacists on their roles in gout management and to identify factors influencing their involvement in gout management. A convenience sample of community pharmacists were invited to participate using a snowballing recruitment strategy. Semi-structured, face-to-face interviews were conducted with 15 pharmacists of varying age, gender and pharmacy experience. Interviews focused on pharmacists' experiences of managing gout, interactions with people living with gout and their perceived roles and responsibilities in gout management. Interviews were transcribed verbatim and independently analysed by two reviewers to identify themes. The main role of pharmacists reported in gout management was providing patient education. The greatest facilitator to pharmacists involvement in gout management was identified to be pharmacists' good understanding of gout and its management. Barriers to pharmacists involvement were identified to be difficulties in monitoring adherence to gout medications, low priority given to gout in the pharmacy compared to other chronic health conditions, and lack of specific training and/or continuing education in gout prevention and management. Pharmacists can expand their primary health care role in gout management, particularly in the area of ongoing provision of education to people living with gout and in monitoring medication adherence in patients. However, a

The Relationship of a Pilot's Educational Background, Aeronautical Experience and Recency of Experience to Performance In Initial Training at a Regional Airline

Science.gov (United States)

Shane, Nancy R.

The purpose of this study was to determine how a pilot's educational background, aeronautical experience and recency of experience relate to their performance during initial training at a regional airline. Results show that variables in pilots' educational background, aeronautical experience and recency of experience do predict performance in training. The most significant predictors include years since graduation from college, multi-engine time, total time and whether or not a pilot had military flying experience. Due to the pilot shortage, the pilots entering regional airline training classes since August 2013 have varied backgrounds, aeronautical experience and recency of experience. As explained by Edward Thorndike's law of exercise and the law of recency, pilots who are actively using their aeronautical knowledge and exercising their flying skills should exhibit strong performance in those areas and pilots who have not been actively using their aeronautical knowledge and exercising their flying skills should exhibit degraded performance in those areas. Through correlation, chi-square and multiple regression analysis, this study tests this theory as it relates to performance in initial training at a regional airline.

Enculturation and attitudes toward intimate partner violence and gender roles in an asian Indian population: implications for community-based prevention.

2014-06-01

This study examined the relationships among enculturation, attitudes supporting intimate partner violence (IPV-supporting attitudes), and gender role attitudes among one of the largest Asian Indian population groups in the US. Data were collected via computer-assisted telephone interviews with a random sample of Gujarati men and women aged 18-64 in Metropolitan Detroit. Using structural equation modeling, we modeled the effects of three components of enculturation (behavior, values, and community participation) on gender role attitudes and IPV-supporting attitudes among married respondents (N = 373). Analyses also accounted for the effects of respondent age, education, religious service attendance, perceived financial difficulty, and lengths of residence in the US. The second-order, overall construct of enculturation was the strongest predictor of IPV-supporting attitudes (standardized B = 0.61), but not gender role attitudes. Patriarchal gender role attitudes were positively associated with IPV-supporting attitudes (B = 0.49). In addition to the overall effect of the enculturation construct, two of the components of enculturation had specific effects. "Enculturation-values" had a specific positive indirect association with IPV-supporting attitudes, through its relationship with patriarchal gender role attitudes. However, "enculturation-community participation" was negatively associated with IPV-supporting attitudes, suggesting the importance of community-based prevention of IPV among this immigrant population group.

Powerless Spectators, Coping Actors, and Adaptive Co-managers: a Synthesis of the Role of Communities in Ecosystem Management

Christo Fabricius

2007-06-01

Full Text Available We provide a synthesis of the papers in the Special Issue, the Communities Ecosystems and Livelihoods component of the Millennium Ecosystem Assessment (MA, and other recent publications on the adaptive capacity of communities and their role in ecosystem management. Communities adapt because they face enormous challenges due to policies, conflicts, demographic factors, ecological change, and changes in their livelihood options, but the appropriateness of their responses varies. Based on our synthesis, three broad categories of adaptive communities are identified. "Powerless spectator" communities have a low adaptive capacity and weak capacity to govern, do not have financial or technological options, and lack natural resources, skills, institutions, and networks. "Coping actor" communities have the capacity to adapt, but are not managing social-ecological systems. They lack the capacity for governance because of lack of leadership, of vision, and of motivation, and their responses are typically short term. "Adaptive manager" communities have both adaptive capacity and governance capacity to sustain and internalize this adaptation. They invest in the long-term management of ecosystem services. Such communities are not only aware of the threats, but also take appropriate action for long-term sustainability. Adaptive co-management becomes possible through leadership and vision, the formation of knowledge networks, the existence or development of polycentric institutions, the establishment and maintenance of links between culture and management, the existence of enabling policies, and high levels of motivation in all role players. Adaptive co-managers are empowered, but empowerment is a consequence of the capacity for governance and the capacity to adapt, rather than a starting point. Communities that are able to enhance their adaptive capacity can deal with challenges such as conflicts, make difficult trade-offs between their short- and long

Godwin, Scott; Bent, Elizabeth; Borneman, James; Pereg, Lily

2012-01-01

Australian Subtropical White Syndrome (ASWS) is an infectious, temperature dependent disease of the subtropical coral Turbinaria mesenterina involving a hitherto unknown transmissible causative agent. This report describes significant changes in the coral associated bacterial community as the disease progresses from the apparently healthy tissue of ASWS affected coral colonies, to areas of the colony affected by ASWS lesions, to the dead coral skeleton exposed by ASWS. In an effort to better understand the potential roles of bacteria in the formation of disease lesions, the effect of antibacterials on the rate of lesion progression was tested, and both culture based and culture independent techniques were used to investigate the bacterial communities associated with colonies of T. mesenterina. Culture-independent analysis was performed using the Oligonucleotide Fingerprinting of Ribosomal Genes (OFRG) technique, which allowed a library of 8094 cloned bacterial 16S ribosomal genes to be analysed. Interestingly, the bacterial communities associated with both healthy and disease affected corals were very diverse and ASWS associated communities were not characterized by a single dominant organism. Treatment with antibacterials had a significant effect on the rate of progress of disease lesions (p = 0.006), suggesting that bacteria may play direct roles as the causative agents of ASWS. A number of potential aetiological agents of ASWS were identified in both the culture-based and culture-independent studies. In the culture-independent study an Alphaproteobacterium closely related to Roseovarius crassostreae, the apparent aetiological agent of juvenile oyster disease, was found to be significantly associated with disease lesions. In the culture-based study Vibrio harveyi was consistently associated with ASWS affected coral colonies and was not isolated from any healthy colonies.

People with a lived experience of mental illness are at a higher risk for developing oral diseases and having poorer oral health than the broader population. This paper explores the role of Australian community mental health services in supporting the prevention and management of poor oral health among people living with mental illness. Through focus groups and semi-structured interviews, participants identified the value of receiving oral health support within a community mental health setting, in particular the delivery of basic education, preventive strategies, assistance with making or attending appointments and obtaining priority access to oral health services. Engagement with Community Health Services and referrals generated through the priority access system were identified as key enablers to addressing oral health issues. This study provides new insight into the importance of undertaking an integrated approach to reducing the oral health disparities experienced by those living with mental illness.

A pivotal role for ocean eddies in the distribution of microbial communities across the Antarctic Circumpolar Current.

Directory of Open Access Journals (Sweden)

Siddarthan Venkatachalam

Full Text Available Mesoscale variability and associated eddy fluxes play crucial roles in ocean circulation dynamics and the ecology of the upper ocean. In doing so, these features are biologically important, providing a mechanism for the mixing and exchange of nutrients and biota within the ocean. Transient mesoscale eddies in the Southern Ocean are known to relocate zooplankton communities across the Antarctic Circumpolar Current (ACC and are important foraging grounds for marine top predators. In this study we investigated the role of cyclonic and anti-cyclonic eddies formed at the South-West Indian Ridge on the spatial variability and diversity of microbial communities. We focused on two contrasting adjacent eddies within the Antarctic Polar Frontal Zone to determine how these features may influence the microbial communities within this region. The water masses and microbiota of the two eddies, representative of a cyclonic cold core from the Antarctic zone and an anti-cyclonic warm-core from the Subantarctic zone, were compared. The data reveal that the two eddies entrain distinct microbial communities from their points of origin that are maintained for up to ten months. Our findings highlight the ecological impact that changes, brought by the translocation of eddies across the ACC, have on microbial diversity.

Lessons Learned from Applying Design Thinking in a NASA Rapid Design Study in Aeronautics

2017-01-01

In late 2015, NASA's Aeronautics Research Mission Directorate (ARMD) funded an experiment in rapid design and rapid teaming to explore new approaches to solving challenging design problems in aeronautics in an effort to cultivate and foster innovation. This report summarizes several lessons learned from the rapid design portion of the study. This effort entailed learning and applying design thinking, a human-centered design approach, to complete the conceptual design for an open-ended design challenge within six months. The design challenge focused on creating a capability to advance experimental testing of autonomous aeronautics systems, an area of great interest to NASA, the US government as a whole, and an entire ecosystem of users and developers around the globe. A team of nine civil servant researchers from three of NASA's aeronautics field centers with backgrounds in several disciplines was assembled and rapidly trained in design thinking under the guidance of the innovation and design firm IDEO. The design thinking process, while used extensively outside the aerospace industry, is less common and even counter to many practices within the aerospace industry. In this report, several contrasts between common aerospace research and development practices and design thinking are discussed, drawing upon the lessons learned from the NASA rapid design study. The lessons discussed included working towards a design solution without a set of detailed design requirements, which may not be practical or even feasible for management to ascertain for complex, challenging problems. This approach allowed for the possibility of redesigning the original problem statement to better meet the needs of the users. Another lesson learned was to approach problems holistically from the perspective of the needs of individuals that may be affected by advances in topic area instead of purely from a technological feasibility viewpoint. The interdisciplinary nature of the design team also

2017-01-01

Aim To examine the characteristics of community health workers (CHWs) involved in diabetes prevention programmes (DPPs) and their contributions to expected outcomes. Methods Electronic databases including PubMed-MEDLINE, EBSCOHost, and SCOPUS/EMBASE were searched for studies published between January 2000 and March 2016. All studies that used CHWs to implement DPP in ≥18-year-old participants without diabetes but at high risk for developing the condition, irrespective of the study design, setting or outcomes measured, were included. Results were synthesized narratively. Results Forty papers of 30 studies were identified. Studies were mainly community-based and conducted in minority populations in USA. Sample sizes ranged from 20 participants in a single community to 2369 participants in 46 communities. Although CHWs were generally from the local community, their qualifications, work experience and training received differed across studies. Overall the training was culturally sensitive and/or appropriate, covering topics such as the importance of good nutrition and the benefits of increased physical activity, communication and leadership. CHWs delivered a variety of interventions and also screened or recruited participants. The shared culture and language between CHWs and participants likely contributed to better programme implementation and successful outcomes. Conclusions The complexity of DPPs and the diverse CHW roles preclude attributing specific outcomes to CHW involvement. Nevertheless, documenting potential CHW roles and the relevant training required may optimise CHW contributions and facilitate their involvement in DPPs in the future. PMID:29216263

Caring for the community.

Nurses can play a unique role in caring for their communities. The first and most obvious role is the direct care of patients, the underlying raison d'etre of nursing, and second is the indirect care of the patients' families and friends. The hands-on healing image of nurses is held by many people and personified through the years by such real-life examples as Clara Barton. It is also the image that attracts many to nursing and is fueled by desire--the desire to help, to make a positive difference, and to serve people. It is often a powerful one-on-one connection between caregiver and receiver, nurse and patient, that defines the role of nursing. Yet, nurses can--and should--play broader roles in caring for their communities. This includes the internal community within one's own organization, the environment in which nurses work, and the larger external community--or communities--in which one lives. By reaching out and caring for the broader communities, nurses have the opportunity to grow while the communities benefit from their participatory caring. In addition, the image of nursing is enhanced externally. The nurse as community caregiver melds the heart and soul of nursing for a new 21st century model of caring.

Community Vitality: The Role of Community-Level Resilience Adaptation and Innovation in Sustainable Development

Directory of Open Access Journals (Sweden)

Lenore Newman

2010-01-01

Full Text Available Community level action towards sustainable development has emerged as a key scale of intervention in the effort to address our many serious environmental issues. This is hindered by the large-scale destruction of both urban neighbourhoods and rural villages in the second half of the twentieth century. Communities, whether they are small or large, hubs of experimentation or loci of traditional techniques and methods, can be said to have a level of community vitality that acts as a site of resilience, adaptation and innovation in the face of environmental challenges. This paper outlines how community vitality acts as a cornerstone of sustainable development and suggests some courses for future research. A meta-case analysis of thirty-five Canadian communities reveals the characteristics of community vitality emerging from sustainable development experiments and its relationship to resilience, applied specifically to community development.

The Role of the Bacterial Community of an Agroecosystem in Simazine Degradation

Directory of Open Access Journals (Sweden)

Roberto Ciccoli

2011-02-01

Full Text Available The use of pesticides and fertilizers in agricultural practice is the main source of soil and groundwater contamination. S-Triazines are among the most used herbicides in the world for selective weed control in several types of crops. The homeostatic capability of an agroecosystem to remove a triazinic herbicide, simazine, was assessed in microcosms treated with the herbicide in presence/absence of urea fertilizer. The latter, as well as a fertilizer, is also one of the last by-products before simazine mineralization. The biodegradation, in terms of disappearance of 50% of the initial concentration (DT50, was compared to the degradation and metabolite formation occurring in sterilized soil. Moreover, the bacterial community response was assessed in terms of abundance and community structure by the epifluorescence direct count method and fluorescence in situ hybridization. The results show that the microbial community has a primary role in simazine degradation and that this process is due to the presence of a microbial pool working in succession and of which the metabolism may be modulated by exogenous sources of nitrogen, like urea. The latter influences the degradative pathway with a greater formation and accumulation of the desethyl-simazine metabolite, which is a hazardous contaminant of soil and groundwater ecosystems, as well as its parent compound.

Building a sense of virtual community: the role of the features of social networking sites.

Chen, Chi-Wen; Lin, Chiun-Sin

2014-07-01

In recent years, social networking sites have received increased attention because of the potential of this medium to transform business by building virtual communities. However, theoretical and empirical studies investigating how specific features of social networking sites contribute to building a sense of virtual community (SOVC)-an important dimension of a successful virtual community-are rare. Furthermore, SOVC scales have been developed, and research on this issue has been called for, but few studies have heeded this call. On the basis of prior literature, this study proposes that perceptions of the three most salient features of social networking sites-system quality (SQ), information quality (IQ), and social information exchange (SIE)-play a key role in fostering SOVC. In particular, SQ is proposed to increase IQ and SIE, and SIE is proposed to enhance IQ, both of which thereafter build SOVC. The research model was examined in the context of Facebook, one of the most popular social networking sites in the world. We adopted Blanchard's scales to measure SOVC. Data gathered using a Web-based questionnaire, and analyzed with partial least squares, were utilized to test the model. The results demonstrate that SIE, SQ, and IQ are the factors that form SOVC. The findings also suggest that SQ plays a fundamental role in supporting SIE and IQ in social networking sites. Implications for theory, practice, and future research directions are discussed.

Smoking is a major public health problem in Qatar. The potential for community pharmacists to offer smoking cessation counseling in this country can be high. To determine the current smoking cessation practices of community pharmacists in Qatar, to examine their attitudes about tobacco use and smoking cessation, to evaluate their perceptions about performing professional roles with respect to smoking cessation and to assess their perceived barriers for smoking cessation counseling in the pharmacy setting in Qatar. Community pharmacies in Qatar. The objectives were addressed in a cross sectional survey of community pharmacists in Qatar from June 2010 to October 2010. A phone call was made to all community pharmacists in Qatar (318 pharmacists) inviting them to participate. Consenting pharmacists anonymously completed the survey either online or as paper using fax. Data was analyzed using Statistical Package of Social Sciences (SPSS®) Version 18. Qatar community pharmacists' smoking cessation practices, their attitudes toward tobacco use, smoking cessation and smoking cessation counseling and their perceived barriers for smoking cessation counseling. Over 5 months, we collected 127 surveys (40 % response rate). Only 21 % of respondents reported that they always or most of the time asked their patients if they smoke. When the patients' smoking status was identified, advising quitting and assessing readiness to quit were always or most of the time performed by 66 and 52 % of respondents respectively. Only 15 % always or most of the time arranged follow-up with smokers and 22 % always or most of the time made smoking cessation referrals. Most respondents (>80 %) agreed that smoking could cause adverse health effects and that smoking cessation could decrease the risk of these effects. In addition, the majority (>80 %) believed that smoking cessation counseling was an important activity and was an efficient use of their time. The top two perceived barriers for smoking

2006-05-01

In response to the demand for innovative microdamage inspection systems, with high sensitivity and undoubted accuracy, we are currently investigating the use and robustness of several acoustic and ultrasonic NDT techniques based on Nonlinear Elastic Wave Spectroscopy (NEWS) for the characterization of microdamage in aeronautical components. In this report, we illustrate the results of an amplitude dependent analysis of the resonance behaviour, both in time (signal reverberation) and in frequency (sweep) domain. The technique is applied to intact and damaged samples of Carbon Fiber Reinforced Plastics (CFRP) composites after thermal loading or mechanical fatigue. The method shows a considerable gain in sensitivity and an incontestable interpretation of the results for nonlinear signatures in comparison with the linear characteristics. For highly fatigued samples, slow dynamical effects are observed.

This paper examines the potential for community conversations to strengthen positive responses to HIV in resource-poor environments. Community conversations are an intervention method through which local people work with a facilitator to collectively identify local strengths and challenges and brainstorm potential strategies for solving local problems. We conducted 18 community conversations (with six groups at three points in time) with a total of 77 participants in rural Zimbabwe (20% HIV positive). Participants were invited to reflect on how they were responding to the challenges of HIV, both as individuals and in community groups, and to think of ways to better support openness about HIV, kindness towards people living with HIV and greater community uptake of HIV prevention and treatment. Community conversations contributed to local HIV competence through (1) enabling participants to brainstorm concrete action plans for responding to HIV, (2) providing a forum to develop a sense of common purpose in relation to implementing these, (3) encouraging and challenging participants to overcome fear, denial and passivity, (4) providing an opportunity for participants to move from seeing themselves as passive recipients of information to active problem solvers, and (5) reducing silence and stigma surrounding HIV. Our discussion cautions that community conversations, while holding great potential to help communities recognize their potential strengths and capacities for responding more effectively to HIV, are not a magic bullet. Poverty, poor harvests and political instability frustrated and limited many participants' efforts to put their plans into action. On the other hand, support from outside the community, in this case the increasing availability of antiretroviral treatment, played a vital role in enabling communities to challenge stigma and envision new, more positive, ways of responding to the epidemic.

2015-12-09

Globally, there is increasing interest in community health worker's (CHW) performance; however, there are gaps in the evidence with respect to CHWs' role in community participation and empowerment. Accredited Social Health Activists (ASHAs), whose roles include social activism, are the key cadre in India's CHW programme which is designed to improve maternal and child health. In a diverse country like India, there is a need to understand how the ASHA programme operates in different underserved Indian contexts, such as rural Manipur. We undertook qualitative research to explore stakeholders' perceptions and experiences of the ASHA scheme in strengthening maternal health and uncover the opportunities and challenges ASHAs face in realising their multiple roles in rural Manipur, India. Data was collected through in-depth interviews (n = 18) and focus group discussions (n = 3 FGDs, 18 participants). Participants included ASHAs, key stakeholders and community members. They were purposively sampled based on remoteness of villages and primary health centres to capture diverse and relevant constituencies, as we believed experiences of ASHAs can be shaped by remoteness. Data were analysed using the thematic framework approach. Findings suggested that ASHAs are mostly understood as link workers. ASHA's ability to address the immediate needs of rural and marginalised communities meant that they were valued as service providers. The programme is perceived to be beneficial as it improves awareness and behaviour change towards maternal care. However, there are a number of challenges; the selection of ASHAs is influenced by power structures and poor community sensitisation of the ASHA programme presents a major risk to success and sustainability. The primary health centres which ASHAs link to are ill-equipped. Thus, ASHAs experience adverse consequences in their ability to inspire trust and credibility in the community. Small and irregular monetary incentives demotivate

2015-01-01

Homelessness is a significant public health problem. It is well-documented that people experiencing homelessness exhibit more serious illnesses and have poorer health than the general population. The provision of services and interventions by health-care professionals, including pharmacists, may make a simple yet important contribution to improved health outcomes in those experiencing homelessness, but evidence of roles and interventions is limited and variable. In Australia, the Queensland University of Technology Health Clinic connects with the homeless community by taking part in community outreach events. This paper provides details of one such event, as well as the roles, interventions and experiences of pharmacists. Participation and inclusion of pharmacists in a multidisciplinary health-care team approach at homeless outreach events should be supported and encouraged.

2016-11-01

This study examined the moderator role of intergenerational family capital on the relationship between community social capital and life satisfaction of older Chinese adults. The data were derived from a quota sampling of 372 older adults aged 60 and above, who were interviewed at four districts in Hong Kong in 2011. Multiple group analysis was employed to examine the proposed model. For the low family capital group, community social capital was found to be a significant predictor of life satisfaction, even when the well-known covariates were controlled. However, the association between community social capital and life satisfaction was statistically non-significant among the high family capital group. The findings highlighted the interplay between community social capital and intergenerational family capital, which supported community social capital replacement theory in understanding the mechanism linking social capital to life satisfaction in older age in a Chinese context. Community social capital can play a compensatory role in maintaining the mental health of older people. It is particularly important for older adults who lack family support and/or suffer from social isolation and loneliness in local communities.

Shown in this paper is an introduction of a prediction tool for the propagation of loud noise with the application to the aeronautics in mind. The tool, named SPnoise, is based on HOWARD approach, which can express almost exact multidimensionality of the diffraction effect at the cost of back scattering. This paper argues, in particular, the prediction of the effect of atmospheric turbulence on sonic boom as one of the important issues in aeronautics. Thanks to the simple and efficient modeling of the atmospheric turbulence, SPnoise successfully re-creates the feature of the effect, which often emerges in the region just behind the front and rear shock waves in the sonic boom signature.

THE ROLE OF LEADERSHIP IN COMMUNITY PARTNERSHIP, ORGANIZATIONAL CHANGES AND DECISION-MAKING PROCESS IN ADDRESSING CRIME ISSUES, AND TERRORISM

2017-09-01

Full Text Available This research paper explains the role of leadership style in building community partnership and in this way also addressing many crime issues and terrorism. The methods used during this research paper are the deep insight of understanding leadership collaboration and organizational changes through literature review. A qualitative design was applied for face-to-face interview with a high ranking member of Kosovo Police. This interview shed light on the role of leadership style and challenges that are related to police reformation and also organizational changes. Through this paper, police leadership may be viewed differently, and seem to be very complex. Community partnership and shared decision-making process were emphasized during this study. This research paper also focused on integrity, ethics and strategic planning. Community partnership, organizational changes, and shared decision-making process are related to leadership style. Leadership style may have either positive or adverse effect on addressing crime rate and terrorism. Depending on the style leaders implement, certain components such as community partnership, or organizational change or even shared decision-making process may fail to function. This is why leadership style seems to bring some very interesting conclusions on this research.

The roles of host evolutionary relationships (genus: Nasonia) and development in structuring microbial communities.

Brucker, Robert M; Bordenstein, Seth R

2012-02-01

The comparative structure of bacterial communities among closely related host species remains relatively unexplored. For instance, as speciation events progress from incipient to complete stages, does divergence in the composition of the species' microbial communities parallel the divergence of host nuclear genes? To address this question, we used the recently diverged species of the parasitoid wasp genus Nasonia to test whether the evolutionary relationships of their bacterial microbiotas recapitulate the Nasonia phylogenetic history. We also assessed microbial diversity in Nasonia at different stages of development to determine the role that host age plays in microbiota structure. The results indicate that all three species of Nasonia share simple larval microbiotas dominated by the γ-proteobacteria class; however, bacterial species diversity increases as Nasonia develop into pupae and adults. Finally, under identical environmental conditions, the relationships of the microbial communities reflect the phylogeny of the Nasonia host species at multiple developmental stages, which suggests that the structure of an animal's microbial community is closely allied with divergence of host genes. These findings highlight the importance of host evolutionary relationships on microbiota composition and have broad implications for future studies of microbial symbiosis and animal speciation. © 2011 The Author(s).

A review of the Magnus effect in aeronautics

Science.gov (United States)

Seifert, Jost

2012-11-01

The Magnus effect is well-known for its influence on the flight path of a spinning ball. Besides ball games, the method of producing a lift force by spinning a body of revolution in cross-flow was not used in any kind of commercial application until the year 1924, when Anton Flettner invented and built the first rotor ship Buckau. This sailboat extracted its propulsive force from the airflow around two large rotating cylinders. It attracted attention wherever it was presented to the public and inspired scientists and engineers to use a rotating cylinder as a lifting device for aircraft. This article reviews the application of Magnus effect devices and concepts in aeronautics that have been investigated by various researchers and concludes with discussions on future challenges in their application.

To investigate the extent to which emotional labour and emotional intelligence are associated with well-being and job-stress among a group of Australian community nurses. The moderating role of emotional intelligence was evaluated as a key factor in the rescue of healthcare workers from job-stress, thus increasing job retention. Although emotional labour has been broadly investigated in the literature, the contribution of emotional labour and emotional intelligence to the well-being and experience of job-stress in a community nursing setting requires further exploration. This study used a cross-sectional quantitative research design with data collected from Australian community nurses. Australian community nurses (n = 312) reported on their perceived emotional labour, emotional intelligence and their levels of well-being and job-stress using a paper and pencil survey in 2010. Results from structural equation modelling support the hypothesis that both emotional labour and emotional intelligence have significant effects on nurses' well-being and perceived job-stress. Emotional intelligence plays a moderating role in the experience of job-stress. These findings provide additional evidence for the important effects that emotional labour and emotional intelligence can have on well-being and job-stress among community nurses. The potential benefits of emotional intelligence in the nurses' emotional work have been explored. © 2013 John Wiley & Sons Ltd.

Australian general practitioners primarily treat mental health problems by prescribing medication dispensed by community pharmacists. Pharmacists therefore have regular interactions with mental health consumers and carers. This narrative review explored the potential role of community pharmacy in mental health services. Medline, CINAHL, ProQuest, Emerald, PsycINFO, Science Direct, PubMed, Web of Knowledge and IPA were utilised. The Cochrane Library as well as grey literature and "lay" search engines such as GoogleScholar were also searched. Four systematic reviews and ten community pharmacy randomised controlled trials were identified. Various relevant reviews outlining the impact of community pharmacy based disease state or medicines management services were also identified. International studies involving professional service interventions for mental health consumers could be contextualised for the Australian setting. Australian studies of pharmacy professional services for chronic physical health conditions provided further guidance for the expansion of community pharmacy mental health professional services.

2015-02-01

In the current study, I describe values for gender roles and cross-sex relations among adolescents growing up in a southern Mexican Maya community in which high school was introduced in 1999. A total of 80 adolescent girls and boys, half of whom were attending the new high school, provided their opinions on two ethnographically derived vignettes that depicted changes in gender roles and relations occurring in their community. Systematic coding revealed that adolescents not enrolled in high school tended to prioritise ascribed and complementary gender roles and emphasise the importance of family mediation in cross-sex relations. Adolescents who were enrolled in high school tended to prioritise equivalent and chosen gender roles, and emphasised personal responsibility and personal fulfillment in cross-sex relations. Perceptions of risks and opportunities differed by gender: girls favourably evaluated the expansion of adult female role options, but saw risks in personal negotiations of cross-sex relations; boys emphasised the loss of the female homemaker role, but favourably evaluated new opportunities for intimacy in cross-sex relations. © 2014 International Union of Psychological Science.

Maternal and infant mortality rates in the district of Chitral in Pakistan are alarmingly high. One of the major reasons for this is the inability of women to access skilled care due to the high costs associated with traveling and utilizing such services. The Aga Khan Health Services, Pakistan (AKHSP) in partnership with the national and provincial Maternal, Neonatal and Child Health (MNCH) program, deployed 28 community midwives (CMWs) in remote villages of Chitral district. This program has also established Community-Based Savings Groups (CBSGs) to support and facilitate access to MNCH services, in particular those delivered by the CMWs. CBSGs are a simple yet cost-effective and sustainable means of providing basic financial services to low income, marginalized, rural populations.The link between CBSGs and utilization of MNCH services is not well understood. This study will assess the relationship between women membership of CBSGs and their utilization of MNCH services, specifically those offered by CMWs, in the community. The research question will be answered through guided interviews of women in the target population who have delivered within one month. The outcome variable will be the utilization of full continuum of skilled MNCH care (disaggregated by 1+ ANC, 1+ PNC and skilled delivery). The primary independent variable of interest will be participation in a CBSG.Focus Group Discussions (FGDs) will be conducted to generate further understanding and information about the social and financial factors that contribute to health behavior and health provider decision-making during pregnancy.Analysis will be tailored to answer how CBSGs, directly or indirectly, facilitate greater financial and/or social access to CMW services for pregnant women. Furthermore, the extent to which financial or social empowerment through a CBSG leads to greater utilization of CMW services. The role of CBSGs and their interlink with the CMWs services to be replicated in other

Blight, Michael G; Ruppel, Erin K; Schoenbauer, Kelsea V

2017-05-01

Although research has explored the ways in which people form virtual communities to converse about media figures, television shows, and similar topics, little research has examined the link between virtual communities and the parasocial relationships (PSRs) that are often the focus of these conversations and users' experiences in those virtual communities. We examined sense of community (SOC) on Twitter and Instagram as a function of users' motives for use and users' PSR on the sites. In addition to examining the relative importance of different motives for using Twitter and Instagram, we predicted that PSR would mediate the association between motives for use and SOC. Results of an online survey revealed that Instagram users (n = 276) reported stronger social interaction motives than did Twitter users (n = 223). Social interaction and expressive information sharing motives were directly positively associated with SOC for users of both sites. Instagram users also exhibited indirect effects of expressive information sharing and companionship motives on SOC, through PSR. These findings suggest potentially influential differences between Twitter and Instagram, particularly regarding the role of PSR in fostering a general SOC.

2013-07-01

In this study, domestic violence (DV) in five African refugee background communities post-settlement in Perth, Australia, is investigated-specifically, the interrelationship between experiences of DV, and changed and changing gender and family roles and responsibilities. The participatory qualitative design utilized in-depth interviews with 54 members of the Somalian, Sierra Leonean, Ethiopian, Liberian and Sudanese Communities, and focus groups with 24 professionals who support them. Three key dimensions of this interrelationship are discussed: "male loss of the breadwinner role and status," "financial independence," and "mismatch between formal response and expectations." The importance of understanding experiences of DV within the context of cultural transition is highlighted here.

Vortex methods in aeronautics: how to make things work

International Nuclear Information System (INIS)

Voutsinas, S.G.

2004-01-01

Vortex methods constitute a particular class in CFD. They are grid-free, they use Lagrangian co-ordinates and most importantly they use vorticity as mail flow variable instead of the velocity. In aeronautics they are in use for over than 20 years with quite impressing results. However, rather a limited number of researchers would prefer them. This could be due to some particularities vortex methods have in their implementation. In view of trying to clarify thins, the present paper reviews the current state of art and details some of the 'difficult' points of vortex methods. Although the focus is mainly on rotor problems, the presented techniques can be used in other applications as well. (author)

McComas, Katherine A.; Stedman, Richard; Sol Hart, P.

2011-01-01

Across the United States, universities are grappling with challenges associated with adopting approaches to more sustainable energy use. One approach has been to develop energy-related projects in their local, host communities. Because host communities can play a major role in the successful planning and implementation of these projects, understanding the factors relating to their support is important. Building on research that suggests that procedural fairness is one such key factor, this study examines community members' support of six approaches a local university could implement to work towards a goal of carbon neutrality. The results of a mail survey (N=677) found that perceived fairness of campus decision makers was significantly related to community support for the proposed approaches; however, beliefs about the efficacy of the different approaches to address challenges associated with climate change had the strongest relationship with support. The results also suggest that residents prefer changes in the energy infrastructure, such as the development of wind power, over the purchase of carbon offsets. We discuss the results in terms of actions that universities may take to foster community engagement in decision-making for university-sponsored sustainable energy projects. - Research highlights: → Residents were surveyed about support of a local university's energy choices. → Perceived fairness of campus authorities related to local support. → Beliefs about ability of energy choices to address climate change predicted support.

The role and results of the European Community's R and D work on radioactive waste management

International Nuclear Information System (INIS)

Orlowski, S.; Girardi, F.

1985-01-01

The titles of R and D programmes generally relate to a scientific discipline, a technology or a project: biotechnology, nuclear fission, etc. This is not so in the case of radioactive wastes, where R and D is focused on the management aspect. The role of R and D in general, and the contribution made by the Community programme in particular, are described and discussed with this in mind. Community R and D in the field of radioactive waste emerges as a powerful tool for establishing a broad consensus on delicate scientific questions such as the feasibility and long-term safety of the final storage of high activity wastes. Such a consensus is based on the many results obtained jointly by Community research teams over the last ten years. The implementation of three projects concerning experimental underground facilities in the context of the Community's new five-year (1985-1989) programme will provide the additional information that is needed before the large industrial disposal facilities of the future can be built

The changing roles of community nurses: the case of health plan nurses in Israel.

Science.gov (United States)

Nissanholtz-Gannot, Rachel; Rosen, Bruce; Hirschfeld, Miriam

2017-12-23

In Israel, approximately one-third of the country's nurses work in community settings - primarily as salaried employees in Israel's four non-profit health plans. Many health system leaders believe that the roles of health plan nurses have changed significantly in recent years due to a mix of universal developments (such as population aging and academization of the profession) and Israel-specific changes (such as the introduction of extensive quality monitoring in primary care). The main objectives of the study were to identify recent changes in the roles of health plan nurses and their current areas of activity. It also explored the experience of front-line nurses with regard to autonomy, work satisfaction, and barriers to further role development. The study integrated interviews and surveys of nurses and other professionals conducted across 4 years. Data generated from earlier study components were used to guide questions and focus for later components. In 2013, in-depth interviews were held with 55 senior nursing and medical professionals supplemented by interviews in mid-2017 with the head nurses in the four health plans. In addition, a national survey was conducted in 2014-5 among a representative sample of 1019 community nurses who work for the health plans and who are engaged in direct patient care. Six hundred ninety-two nurses responded to the survey, yielding a response rate of 69%. The survey sample consisted of an equal number of nurses from each health plan, and the observations were weighted accordingly. Senior professionals identified general themes associated with a shift in nursing roles, including a transition from reactive to initiated work, increased specialization, and a shifting of tasks from hospitals to community settings. They identified the current main areas of activity in the health plans as being: routine care, chronic care, health promotion, quality monitoring and improvement, specialized care (such as wound care), and home care.

2015-07-01

Full Text Available Teerapon Dhippayom,1 Ines Krass21Pharmaceutical Care Research Unit, Department of Pharmacy Practice, Faculty of Pharmaceutical Sciences, Naresuan University, Phitsanulok, Thailand; 2Faculty of Pharmacy, The University of Sydney, Camperdown, NSW, AustraliaBackground: Evidence supports the efficacy of pharmacy services in type 2 diabetes (T2D. However, little is known about consumer perspectives on the role of community pharmacists in diabetes care. The objectives of this study were to identify potential unmet needs and explore preferences for pharmacist-delivered support for T2D.Methods: A qualitative study using focus groups was conducted in Sydney, Australia. Patients with T2D who were members of the Australian Diabetes Council in Sydney, Australia, were recruited through a survey on medication use in T2D. Five focus groups with a total of 32 consumers with T2D were recorded, transcribed, and thematically analyzed.Results: The key themes were 1 the experiences of diabetes services received, 2 the potential to deliver self-management services, and 3 the suggested role of pharmacist in supporting diabetes management. Gaps in understanding and some degree of nonadherence to self-management signaled a potential for self-management support delivered by pharmacists. However, consumers still perceive that the main role of pharmacists in diabetes care centers on drug management services, with some enhancements to support adherence and continuity of supply. Barriers to diabetes care services included time constraints and a perceived lack of interest by pharmacists.Conclusion: Given the unmet needs in diabetes self-management, opportunities exist for pharmacists to be involved in diabetes care. The challenge is for pharmacists to upgrade their diabetes knowledge and skills, organize their workflow, and become proactive in delivering diabetes care support.Keywords: diabetes care, community pharmacy, community pharmacist, self-management, preference

The role of community pharmacists in screening and subsequent management of chronic respiratory diseases: a systematic review.

Science.gov (United States)

Fathima, Mariam; Naik-Panvelkar, Pradnya; Saini, Bandana; Armour, Carol L

2013-10-01

The purpose of this review was to evaluate the role of community pharmacists in provision of screening with/without subsequent management of undiagnosed chronic obstructive pulmonary disease (COPD) and uncontrolled asthma. An extensive literature search using four databases (ie. Medline, PubMed, International Pharmaceutical Abstracts (IPA) and Scopus) with search terms pharmacy, screening, asthma or COPD was conducted. Searches were limited to the years 2003-2013, those in English and those reporting research with humans. Data retrieval, analysis and result presentation employed a scoping review method. Seventeen articles met the inclusion/exclusion criteria, of which fifteen studies were based on people with asthma and two were based on people with COPD. Only seven asthma studies and one COPD study involved screening followed by subsequent management. More than half of the people screened were found to be poorly controlled and up to 62% of people were identified at high risk for COPD by community pharmacists. The studies varied in the method and type of asthma control assessment/screening, the type of intervention provided and the outcomes measured. The limitations of the reviewed studies included varying definitions of asthma control, different study methodologies, and the lack of long-term follow-up. While many different methods were used for risk assessment and management services by the pharmacists, all the studies demonstrated that community pharmacists were capable of identifying people with poorly controlled asthma and undiagnosed COPD and providing them with suitable interventions. The literature review identified that community pharmacists can play an effective role in screening of people with poorly controlled asthma and undiagnosed COPD along with delivering management interventions. However, there is very little literature available on screening for these chronic respiratory conditions. Future research should focus on development of patient care

The Role of Multicultural Media in Connecting Municipal Governments with Ethnocultural Communities: The Case of Ottawa

Directory of Open Access Journals (Sweden)

Luisa Veronis

2015-12-01

Full Text Available This paper aims to advance understanding of the role ethnic and multicultural media can play in connecting municipal governments and Ethnocultural and Immigrant Communities (EICs. Using an innovative mixed-methods approach and methodological triangulation, we compare the access to and use of multicultural media among four EICs—the Chinese, Latin American, Somali and South Asian—in Ottawa, Canada. Our cross-comparative study yields three main findings: 1 members of participating communities proactively and strategically use a variety of sources to access information about local services; 2 noteworthy differences exist in the access to and use of different types of media both across and within the four EICs, due to demographic and cultural differences; and 3 participants shared challenges and opportunities that multicultural media afford to better connect municipal government and EICs. The paper’s findings make important empirical contributions to the literature on the integrative potential of ethnic and multicultural media by strengthening the reliability of data, validity of findings, and broadening and deepening understanding the role multicultural media play in promoting collaboration between city governments and diverse EICs.

Corkindale, David; Ram, Jiwat; Chen, Howard

2018-02-01

Online communities are a powerful device for collaborative creativity and innovation. Developments in Web 2.0 technologies have given rise to such interactions through firm-hosted online communities (FHOCs) - firm-run online information services that also provide self-help to a community. We devise a model that seeks to explain the factors that encourage people to become members of a FHOC and test the model using structural equation modelling based on data collected from 511 users of a FHOC. The study finds that: (a) an understanding of Perceived Usefulness (PU) plays a mediating role between Behavioural Intention (BI) to adopt FHOC and Trust, as well as Interface design; b) Networking among users has an indirect effect on BI; and c) design of the Interface has a direct influence on BI. A managerial implication is that Networking plays a role in the way supplementary services, including blogs and discussion forums, are perceived. Theoretically, when service quality is decomposed into components such as core services and supplementary services, it also positively influences PU.

. Perception related to the quality of management, administration, physical environment of the service point and satisfaction addressing health promotion and women health issues played significant role on community clinic's services utilization. Besides parental education and income, client's perception and satisfaction played significant role in community clinic service utilization. Provider's perception of service quality should be studied. The study findings will enable policy-makers to improve quality of primary health care services, realizing providers' and patients' ideas of community clinic service quality.

An Opportunity for Healing and Holistic Care: Exploring the Roles of Health Care Providers Working Within Northern Canadian Aboriginal Communities.

Science.gov (United States)

Rahaman, Zaida; Holmes, Dave; Chartrand, Larry

2016-05-22

The purpose of this qualitative study was exploring what the roles and challenges of health care providers working within Northern Canadian Aboriginal communities are and what resources can help support or impede their efforts in working toward addressing health inequities within these communities. The qualitative research conducted was influenced by a postcolonial epistemology. The works of theorists Fanon on colonization and racial construction, Kristeva on semiotics and abjection, and Foucault on power/knowledge, governmentality, and biopower were used in providing a theoretical framework. Critical discourse analysis of 25 semistructured interviews with health care providers was used to gain a better understanding of their roles and challenges while working within Northern Canadian Aboriginal communities. Within this research study, three significant findings emerged from the data. First, the Aboriginal person's identity was constructed in relation to the health care provider's role of delivering essential health services. Second, health care providers were not treating the "ill" patient, but rather treating the patient for being "ill." Third, health care providers were treating the Aboriginal person for being "Aboriginal" by separating the patient from his or her identity. The treatment involved reforming the Aboriginal patient from the condition of being "Aboriginal." © The Author(s) 2016.

TEXTILE STRUCTURES FOR AERONAUTICS (PART I

SOLER Miquel

2014-05-01

Full Text Available Three-dimensional (3D textile structures with better delamination resistance and damage impact tolerance to be applied in composites for structural components is one of the main goals of the aeronautical industry. Textile Research Centre in Canet de Mar has been working since 2008 in this field. Our staff has been designing, developing and producing different textile structures using different production methods and machinery to improve three-dimensional textile structures as fiber reinforcement for composites. This paper describes different tests done in our textile labs from unidirectional structures to woven, knitted or braided 3 D textile structures. Advantages and disadvantages of each textile structure are summarized. The first part of this paper deals with the introduction of our Textile Research Centre in the field of composites and carbon fiber as a main material to produce three – dimensional textile structures. The use of composite materials in aerospace structures has increased over the past decades. Our contribution related to this field consists of the development of three- dimensional textile structures and even the adaptation and improvement of machinery to do it possible. Carbon fiber provides advantages as volumetric fraction and minimum fault occurrence. However carbon fiber has also disadvantages as uncomfortable handling delamination and high cost of material and processing.

Observation of Online Communities: A Discussion of Online and Offline Observer Roles in Studying Development, Cooperation and Coordination in an Open Source Software Environment

Directory of Open Access Journals (Sweden)

Sladjana V. Nørskov

2011-09-01

Full Text Available This paper addresses the application of observation to online settings with a special focus on observer roles. It draws on a study of online observation of a virtual community, i.e. an open source software (OSS community. The paper examines general and specific advantages and disadvantages of the observer roles in online settings by relating these roles to the same roles assumed in offline settings. The study suggests that under the right circumstances online and offline observation may benefit from being combined as they complement each other well. Quality issues and factors important to elicit trustworthy observational data from online study settings, such as OSS communities, are discussed. A proposition is made concerning how threats to credibility and transferability in relation to online observation (i.e. lack of richness and detail, risk of misunderstandings can be diminished, while maintaining the level of dependability (which is potentially high due to a greater degree of anonymity and "isolation" in online settings. The paper thus suggests that the less participative the researcher's online observer role is, the more s/he should consider introducing offline data collection techniques rather than adopting a more participative role in the observed online setting. This methodological discussion forms the basis for making a well-considered choice of online observer role rather than passively sliding into a role assigned by the setting.

Arc tracking tests have been carried out between two voluntarily damaged aeronautic cables. Copper or aluminum conductors have been exposed to short circuits under alternating current. Various data have been recorded (arc voltage and current, radiated power and ablated mass), enabling to determine a power balance, in which every contribution is estimated. The total power is mainly transferred to the cables (between 50 and 65%, depending on the current and the cable type), and causes the melting and partial vaporization of the metallic core and insulating material, or is conducted or radiated. The other part is deposited into the arc column, being either radiated, convected or conducted. (paper)

The Role of Nurses and Community Health Workers in Confronting Neglected Tropical Diseases in Sub-Saharan Africa: A Systematic Review.

Science.gov (United States)

Corley, Andrew G; Thornton, Clifton P; Glass, Nancy E

2016-09-01

Neglected tropical diseases produce an enormous burden on many of the poorest and most disenfranchised populations in sub-Saharan Africa. Similar to other developing areas throughout the world, this region's dearth of skilled health providers renders Western-style primary care efforts to address such diseases unrealistic. Consequently, many countries rely on their corps of nurses and community health workers to engage with underserved and hard-to-reach populations in order provide interventions against these maladies. This article attempts to cull together recent literature on the impact that nurses and community health workers have had on neglected tropical diseases. A review of the literature was conducted to assess the role nurses and community health workers play in the primary, secondary, and tertiary prevention of neglected tropical diseases in sub-Saharan Africa. Articles published between January 2005 and December 2015 were reviewed in order to capture the full scope of nurses' and community health workers' responsibilities for neglected tropical disease control within their respective countries' health systems. A total of 59 articles were identified that fit all inclusion criteria. Successful disease control requires deep and meaningful engagement with local communities. Expanding the role of nurses and community health workers will be required if sub-Saharan African countries are to meet neglected tropical disease treatment goals and eliminate the possibility future disease transmission. Horizontal or multidisease control programs can create complimentary interactions between their different control activities as well as reduce costs through improved program efficiencies-benefits that vertical programs are not able to attain.

Lindeman, Melissa; Mackell, Paulene; Lin, Xiaoping; Farthing, Annie; Jensen, Heather; Meredith, Maree; Haralambous, Betty

2017-06-01

To explore the role art centres in remote communities play for Aboriginal and Torres Strait Islander Australians living with dementia. A comprehensive literature search was undertaken, with no restrictions on articles regarding year of publication. Art programmes have been found to be of benefit to both people living with dementia and their carers, particularly when programmes are administered in environments that are culturally revered. Findings indicate remote art centres play a key role in maintaining traditions, culture and practices unique to Aboriginal and Torres Strait Islanders, but there is a gap in knowledge regarding how they cater for the needs of people with dementia. Addressing this gap will be helpful in remote areas where prevalence of dementia is up to five times that of non-Aboriginal people, and there are limited health and support services. Further research is required to explore strengths and gaps of current practices. © 2017 AJA Inc.

Inter-Provincial Migration Intentions of Family Physicians in Canada: The Roles of Income and Community Characteristics.

Science.gov (United States)

Mou, Haizhen; Olfert, M Rose

2015-11-01

The inter-provincial migration patterns of family physicians in canada show that some provinces like newfoundland and saskatchewan experience persistent net out-migration, while others, including ontario and british columbia, are destinations more often than origins of migrants. Governments in provinces exhibiting net out-migration have responded with a number of incentive and recruitment programs. In this study, we investigate the determinants of the stated interprovincial migration intentions of 3,995 rural and urban family physicians in the 2010 wave of the national physician survey. We consider a range of physician characteristics, community attributes and working conditions. We find that in the intention to move, higher compensation has a modest effect, while the community characteristics have a consistently important influence. Our results suggest that policy and program designers should acknowledge the critical role of community-level living and working conditions in their family physician recruitment and retention efforts.

Role of community pharmacists in asthma - Australian research highlighting pathways for future primary care models.

Science.gov (United States)

Saini, B; Krass, I; Smith, L; Bosnic-Anticevich, S; Armour, C

2011-01-01

Asthma is one of the most common chronic conditions affecting the Australian population. Amongst primary healthcare professionals, pharmacists are the most accessible and this places pharmacists in an excellent position to play a role in the management of asthma. Globally, trials of many community pharmacy-based asthma care models have provided evidence that pharmacist delivered interventions can improve clinical, humanistic and economic outcomes for asthma patients. In Australia, a decade of coordinated research efforts, in various aspects of asthma care, has culminated in the implementation trial of the Pharmacy Asthma Management Service (PAMS), a comprehensive disease management model.There has been research investigating asthma medication adherence through data mining, ways in which usual asthma care can be improved. Our research has focused on self-management education, inhaler technique interventions, spirometry trials, interprofessional models of care, and regional trials addressing the particular needs of rural communities. We have determined that inhaler technique education is a necessity and should be repeated if correct technique is to be maintained. We have identified this effectiveness of health promotion and health education, conducted within and outside the confines of the pharmacy, in public for a and settings such as schools, and established that this outreach role is particularly well received and increases the opportunity for people with asthma to engage in their asthma management.Our research has identified that asthma patients have needs which pharmacists delivering specialized models of care, can address. There is a lot of evidence for the effectiveness of asthma care by pharmacists, the future must involve integration of this role into primary care.

The role of community health centers in assessing the social determinants of health for planning and policy: the example of frontier New Mexico.

Bruna, Sean; Stone, Lisa Cacari; Wilger, Susan; Cantor, Jeremy; Guzman, Carolina

2014-01-01

This article examines the experience of a frontier-based community health center when it utilized the Tool for Health and Resilience in Vulnerable Environments (THRIVE) for assessing social determinants of health with a local health consortium. Community members (N = 357) rated safety, jobs, housing, and education among the top health issues. Community leaders integrated these health priorities in a countywide strategic planning process. This example of a frontier county in New Mexico demonstrates the critical role that community health centers play when engaging with local residents to assess community health needs for strategic planning and policy development.

Towards eliminating malaria in high endemic countries: the roles of community health workers and related cadres and their challenges in integrated community case management for malaria: a systematic review.

Sunguya, Bruno F; Mlunde, Linda B; Ayer, Rakesh; Jimba, Masamine

2017-01-03

Human resource for health crisis has impaired global efforts against malaria in highly endemic countries. To address this, the World Health Organization (WHO) recommended scaling-up of community health workers (CHWs) and related cadres owing to their documented success in malaria and other disease prevention and management. Evidence is inconsistent on the roles and challenges they encounter in malaria interventions. This systematic review aims to summarize evidence on roles and challenges of CHWs and related cadres in integrated community case management for malaria (iCCM). This systematic review retrieved evidence from PubMed, CINAHL, ISI Web of Knowledge, and WHO regional databases. Terms extracted from the Boolean phrase used for PubMed were also used in other databases. The review included studies with Randomized Control Trial, Quasi-experimental, Pre-post interventional, Longitudinal and cohort, Cross-sectional, Case study, and Secondary data analysis. Because of heterogeneity, only narrative synthesis was conducted for this review. A total of 66 articles were eligible for analysis out of 1380 studies retrieved. CHWs and related cadre roles in malaria interventions included: malaria case management, prevention including health surveillance and health promotion specific to malaria. Despite their documented success, CHWs and related cadres succumb to health system challenges. These are poor and unsustainable finance for iCCM, workforce related challenges, lack of and unsustainable supply of medicines and diagnostics, lack of information and research, service delivery and leadership challenges. Community health workers and related cadres had important preventive, case management and promotive roles in malaria interventions. To enable their effective integration into the health systems, the identified challenges should be addressed. They include: introducing sustainable financing on iCCM programmes, tailoring their training to address the identified gaps

2003-09-01

Community gardens enhance nutrition and physical activity and promote the role of public health in improving quality of life. Opportunities to organize around other issues and build social capital also emerge through community gardens. California Healthy Cities and Communities (CHCC) promotes an inclusionary and systems approach to improving community health. CHCC has funded community-based nutrition and physical activity programs in several cities. Successful community gardens were developed by many cities incorporating local leadership and resources, volunteers and community partners, and skills-building opportunities for participants. Through community garden initiatives, cities have enacted policies for interim land and complimentary water use, improved access to produce, elevated public consciousness about public health, created culturally appropriate educational and training materials, and strengthened community building skills.

Do Community Characteristics Relate to Young Adult College Students' Credit Card Debt? The Hypothesized Role of Collective Institutional Efficacy.

Science.gov (United States)

Friedline, Terri; West, Stacia; Rosell, Nehemiah; Serido, Joyce; Shim, Soyeon

2017-03-01

This study examines the extent of emergent, outstanding credit card debt among young adult college students and investigates whether any associations existed between this credit card debt and the characteristics of the communities in which these students grew up or lived. Using data (N = 748) from a longitudinal survey and merging community characteristics measured at the zip code level, we confirmed that a community's unemployment rate, average total debt, average credit score, and number of bank branch offices were associated with a young adult college student's acquisition and accumulation of credit card debt. For example, a community's higher unemployment rate and lower number of bank branches were associated with a young adult college student's greater accumulated debt. Community characteristics had the strongest associations with credit card debt, especially after controlling for individual characteristics (i.e., a young adult college student's race and financial independence) and familial characteristics (i.e., their parents' income and parents' discussions of financial matters while growing up at home). The findings may help to understand the unique roles that communities play in shaping children and young adults' financial capability, and how communities can be better capacitated to support the financial goals of their residents. © Society for Community Research and Action 2017.

Online communities of practice and their role in educational development: a systematic appraisal.

Science.gov (United States)

Swift, Lynn

2014-04-01

Practice teachers and academics have a role in developing knowledge and promoting evidence-based practice with their students in a supportive and creative learning environment. Recent advances in technology are enabling communities of practice' (CoPs) to be developed online and may present a valuable opportunity to form greater connections between educators. To explore this idea, the author conducted a systematic appraisal of published evidence relating to the impact of using an online CoP (OCoP) to develop knowledge among healthcare educators. Three academic databases were targeted for articles and the search retrieved nine articles that were analysed for quality. The findings identified that an OCoP offers a 'polycontextual' environment that can enhance knowledge development, strengthen social ties and build social capital. Communities that support tacit knowledge development, information sharing and problem solving are most valued and existing information and communication technology (ICT) tools can be used to promote usability and accessibility. Recognising the value of tacit knowledge and using ICT for educational development within workload hours will require a shift in cultural thinking at both an individual and organisational level.

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.

Applied simulation and optimization in logistics, industrial and aeronautical practice

CERN Document Server

Mota, Idalia; Serrano, Daniel

2015-01-01

Presenting techniques, case-studies and methodologies that combine the use of simulation approaches with optimization techniques for facing problems in manufacturing, logistics, or aeronautical problems, this book provides solutions to common industrial problems in several fields, which range from manufacturing to aviation problems, where the common denominator is the combination of simulation’s flexibility with optimization techniques’ robustness. Providing readers with a comprehensive guide to tackle similar issues in industrial environments, this text explores novel ways to face industrial problems through hybrid approaches (simulation-optimization) that benefit from the advantages of both paradigms, in order to give solutions to important problems in service industry, production processes, or supply chains, such as scheduling, routing problems and resource allocations, among others.

The relative importance of stochasticity versus determinism in soil bacterial communities is unclear, as are the possible influences that alter the balance between these. Here, we investigated the influence of spatial scale on the relative role of stochasticity and determinism in agricultural monocultures consisting only of wheat, thereby minimizing the influence of differences in plant species cover and in cultivation/disturbance regime, extending across a wide range of soils and climates of the North China Plain (NCP). We sampled 243 sites across 1092 km and sequenced the 16S rRNA bacterial gene using MiSeq. We hypothesized that determinism would play a relatively stronger role at the broadest scales, due to the strong influence of climate and soil differences in selecting many distinct OTUs of bacteria adapted to the different environments. In order to test the more general applicability of the hypothesis, we also compared with a natural ecosystem on the Tibetan Plateau. Our results revealed that the relative importance of stochasticity vs. determinism did vary with spatial scale, in the direction predicted. On the North China Plain, stochasticity played a dominant role from 150 to 900 km (separation between pairs of sites) and determinism dominated at more than 900 km (broad scale). On the Tibetan Plateau, determinism played a dominant role from 130 to 1200 km and stochasticity dominated at less than 130 km. Among the identifiable deterministic factors, soil pH showed the strongest influence on soil bacterial community structure and diversity across the North China Plain. Together, 23.9% of variation in soil microbial community composition could be explained, with environmental factors accounting for 19.7% and spatial parameters 4.1%. Our findings revealed that (1) stochastic processes are relatively more important on the North China Plain, while deterministic processes are more important on the Tibetan Plateau; (2) soil pH was the major factor in shaping

Community energy planning in Canada. The role of renewable energy

International Nuclear Information System (INIS)

St Denis, Genevieve; Parker, Paul

2009-01-01

An emerging trend in Canada is the creation of community energy plans, where decisions that used to be left to regional level energy agencies or private individuals are now being considered at the community level. A desire to reduce greenhouse gas emissions and to become more energy self-sufficient is driving this change. Theoretically, local level management is desirable because it achieves these goals through improvements in the three areas of energy efficiency, energy conservation and switching to renewable energy sources. The analysis of 10 of the first community energy plans in Canadian communities, ranging in population size from 500 to one million, finds that communities are choosing policies and programs centred on increasing energy efficiency and conservation while renewable energy receives much less attention. Municipal operations were called upon to set higher targets than the general community. Communities that recognized the substantial potential of renewable energy often focused on technologies that the municipal sector could implement, such as bio-fuels for their transportation fleet. Wind, passive solar design, solar photovoltaics and solar thermal options were only recommended in a few cases. Overall, only one of the five larger communities (Calgary) recommended implementing multiple renewable energy technologies while three of the five smaller communities proposed multiple renewable energy sources. The implication is that smaller and more remote communities may be the most willing to lead in the planned introduction of renewable energy systems. (author)

The role of community pharmacists in screening and subsequent management of chronic respiratory diseases: a systematic review

Fathima, Mariam; Naik-Panvelkar, Pradnya; Saini, Bandana; Armour, Carol L.

Objective The purpose of this review was to evaluate the role of community pharmacists in provision of screening with/without subsequent management of undiagnosed chronic obstructive pulmonary disease (COPD) and uncontrolled asthma. Methods An extensive literature search using four databases (ie. Medline, PubMed, International Pharmaceutical Abstracts (IPA) and Scopus) with search terms pharmacy, screening, asthma or COPD was conducted. Searches were limited to the years 2003-2013, those in English and those reporting research with humans. Data retrieval, analysis and result presentation employed a scoping review method. Results Seventeen articles met the inclusion/exclusion criteria, of which fifteen studies were based on people with asthma and two were based on people with COPD. Only seven asthma studies and one COPD study involved screening followed by subsequent management. More than half of the people screened were found to be poorly controlled and up to 62% of people were identified at high risk for COPD by community pharmacists. The studies varied in the method and type of asthma control assessment/screening, the type of intervention provided and the outcomes measured. The limitations of the reviewed studies included varying definitions of asthma control, different study methodologies, and the lack of long-term follow-up. While many different methods were used for risk assessment and management services by the pharmacists, all the studies demonstrated that community pharmacists were capable of identifying people with poorly controlled asthma and undiagnosed COPD and providing them with suitable interventions. Conclusions The literature review identified that community pharmacists can play an effective role in screening of people with poorly controlled asthma and undiagnosed COPD along with delivering management interventions. However, there is very little literature available on screening for these chronic respiratory conditions. Future research should focus

AIRPORT NOISE CHARGES AND LOCAL COMMUNITIES: APPLICATION TO REGIONAL AIRPORTS

Directory of Open Access Journals (Sweden)

LUCA MANTECCHINI

2016-11-01

Full Text Available There have always been conflicts among airports and local communities due to the aeronautical noise generated by airport operations. In fact, this is a factor that - if not properly managed - could severely cut down the growth of air traffic in an airport with direct effects on the economic and territorial system. Beside this, in the last decade the critical issues related to the impact of aeronautical noise on airport operations have greatly reduced, thanks to technological improvements in aircraft design. Nevertheless, the reduction of noise emissions during a single aircraft operation does not make the issue of the airports’ location less important. This is the case of regional airports in EU, which have recently experimented a large traffic increase due to the development of low-cost traffic. It is now clear that the problem cannot be reduced to its mere technological aspect, but it ought to be dealt with the involvement of the various stakeholders in order to mitigate the emissions and adequately compensate the impacts to local communities. Typically, there are two possible countermeasures to mitigate the effects of aircraft noise: operational measures, based on the application of technological and organizational devices and market-based measures. The application of noise taxes, aiming at compensating the negative externalities generated by airport operations is becoming increasingly widespread in EU. In this paper, a methodology for the application of noise taxes based on the actual noise of aircraft operating into an airport is discussed and implemented in a test case.

The Role of Reconciling Values in Efforts to Build Community Resilience to Global Environmental Change

Science.gov (United States)

Rainie, S. C.; Ferguson, D. B.; Martinez, A.

2017-12-01

Global environmental change has increasingly forced researchers and policy makers to reckon with the practical and philosophical need to integrate Indigenous knowledge with western science to support sustainable, resilient communities. Despite the recognition that integration of different ways of knowing offers a compelling approach for building long-term resilience, balancing the power dynamic that favors mainstream epistemologies over other ways of knowing remains elusive. Indigenous scholars themselves often speak of "walking in two worlds," acknowledging the distinction between Indigenous knowledge and western science and the difficulty of weaving together the two approaches. Central to the distinction between different ways of knowing are the core values that drive development and application of new knowledge. The DIKW pyramid describes the hierarchical relationships between wisdom, knowledge, information, and data. In these relationships, values drive how one turns data into information, then knowledge and wisdom. Thus, if building community resilience relies on integrating Indigenous science and Western science, a central point of focus must be on establishing which of the core values from these different knowledge systems can contribute and which may impede the goal of supporting community resilience. For example, does the absence of Western science data collection protocols (a core value of empirical science) eliminate the utility of community observations of environmental change from efforts to understand system change? Indigenous data sovereignty, an emerging framework, asserts Indigenous rights to information and promotes the role of community knowledge in creating metrics, outcomes, and ultimately actions toward resilient communities. Indigenous data sovereignty acknowledges that context and values shape data in addition to providing a lens for interpreting data. Can principles for the governance of Indigenous data, such as recognizing and supporting

The relationship between risk factors and aeronautical decision making in the flight training environment

Science.gov (United States)

Wetmore, Michael J.

The purpose of this applied dissertation was to investigate the relationship between risk factors and aeronautical decision making in the flight training environment using a quantitative, non-experimental, ex post facto research design. All 75 of the flight training accidents that involved a fatality from the years 2001-2003 were selected for study from the National Transportation Safety Board (NTSB) aviation accident database. Objective evidence from the Factual Reports was used to construct accident chains and to code and quantify total risk factors and total poor aeronautical decisions. The data were processed using correlational statistical tests at the 1% significance level. There was a statistically significant relationship between total risk factors per flight and poor decisions per flight. Liveware risks were the most prevalent risk factor category. More poor decisions were made during preflight than any other phase of flight. Pilots who made multiple poor decisions per flight had significantly higher risk factors per flight. A risk factor threat to decision making chart is presented for use by flight instructors and/or flight training organizations. The main threat to validity of this study was the NTSB accident investigation team investigative equality assumption.

Highlights: ► Develops a comprehensive literature review on ethanol flammability limits. ► Difference in standard procedures lead to different experimental values of the flammability limits. ► Methodology for experiments to find the FL's of ethanol for aeronautical applications. - Abstract: The lower and upper flammability limits of a fuel are key tools for predicting fire, assessing the possibility of explosion, and designing protection systems. Knowledge about the risks involved with the explosion of both gaseous and vaporized liquid fuel mixtures with air is very important to guarantee safety in industrial, domestic, and aeronautical applications. Currently, most countries use various standard experimental tests, which lead to different experimental values for these limits. A comprehensive literature review of the flammability limits of combustible mixtures is developed here in order to organize the theoretical and practical knowledge of the subject. The main focus of this paper is the review of the flammability data of ethanol–air mixtures available in the literature. In addition, the description of methodology for experiments to find the upper and lower limits of flammability of ethanol for aeronautical applications is discussed. A heated spherical 20 L vessel was used. The mixtures were ignited with electrode rods placed in the center of the vessel, and the spark gap was 6.4 mm. LFL and the UFL were determined for ethanol (hydrated ethanol 96% °INPM) as functions of temperature for atmospheric pressure to compare results with data published in the scientific literature.

Journey in Aeronautical Research: A Career at NASA Langley Research Center. No. 12; Monographs in Aerospace History

Phillips, W. Hewitt

1998-01-01

An autobiography, of a noted aeronautical engineer, W. Hewitt Phillips, whose career spanned 58 years (1940-1998) at NASA Langley is presented. This work covers his early years to the Sputnik launch. His interests have been in research in aeronautics and in the related problems of spaceflight. After an introduction, his early life through the college years is reviewed, and his early interest in model airplanes is described. The first assignment for the National Advisory Committee for Aeronautics (NACA), which would later become NASA, was with the Flight Research Division. His early work involved "Flying Qualities", i.e., the stability and control characteristics of an airplane. The next chapter describes his early analytical studies. His work during World War II in the design of military airplanes, and the other effects of the war on research activities, is covered in the next two chapters. This research was involved in such innovations and refinements as the swept wing, the flettner tabs, servo tabs, spring tabs and whirlerons. The rest of the work covers the research which Mr. Hewitt was involved in, after the war until the Sputnik launch. These areas include unsteady lift, measurements of turbulence in the atmosphere, gust alleviation, and lateral response to random turbulence. He was also involved in several investigations of airplane accidents. The last two chapters cover the administration of the Langley Research Center, and the dawn of the Space Age. A complete bibliography of reports written by Mr. Hewitt, is included.

Full Text Available This paper presents the sharing analysis of the 694–790 MHz frequency band for Mobile services IMT and Aeronautical radio-navigation services (ARNS using SEAMCAT (established by CEPT software based on the statistical simulation (Monte-Carlo method. In 2012 the World Radiocommunication Conference (WRC-12 decided to allocate the 694–790 MHz frequency band (the so-called 700 MHz band to mobile services IMT (excluding aeronautical mobile after WRC-15 conference. But this agreement raises electromagnetic compatibility problems, which should be solved until WRC-15 [1]. This study was carried out in two phases: first applying theoretical analysis, then statistical Monte-Carlo simulations with SEAMCAT software tool in order to verify results obtained in theoretical approach. Analytical calculations shows that the required protection distances between ARNS stations and the MS base stations are 132 km. The obtained results from SEAMCAT simulations indicate that separation distance should be above 100 km. These results illustrate that the systems are not electromagnetically compatible. The possible mitigation technic could be antenna pattern correction.

Our manuscript highlights the viewpoints and reflections of the native Marshallese community health workers (CHWs) engaged in research with the local Marshallese community in Northwest Arkansas. In particular, this paper documents the vital role Marshallese CHWs play in the success of programs and research efforts. The negative health effects of nuclear testing in the Marshall Islands has been passed down through many generations, along with unfavorable attitudes toward the U.S. government and researchers. However, the community-based participatory research (CBPR) approach used by the University of Arkansas for Medical Sciences (UAMS) has allowed the native Marshallese CHWs to become advocates for the Marshallese community. The use of native CHWs has also leveled the power dynamics that can be a barrier to community-based research, and has strengthened trust with community stakeholders. Our paper shows how using Marshallese CHWs can produce positive health outcomes for the Marshallese community.

The key role played by forensic community mental health nurses in statutory community aftercare for mentally disordered offenders in England and Wales has been successful. The nurses often have the most contact with this patient population, yet paradoxically, have not been asked to express their views about the process. The pivotal role undertaken by this professional group appears to be fundamental to the success of statutory aftercare for this patient group.

To describe the role, contribution and value of research nurses in New Zealand community-based or primary health care research. Research nurses are increasingly recognised as having a key role in undertaking successful research in hospitals and clinical trial units however only limited work has been undertaken to examine their role in community-based research. Undertaking health research in the community has unique challenges particularly in relation to research design and recruitment and retention of participants. We describe four community-based research projects involving research nurses, each with particular recruitment, retention and logistical problems. Vignettes are used to illustrate the role, contribution and value of research nurses in a diverse range of community research projects. The knowledge and skills used by research nurses in these projects included familiarity with communities, cultural competence, health care systems and practice philosophies and in particular with vulnerable populations. Their research actions and activities include competence with a broad range of research methodologies, organisational efficiency, family-centred approach, along with advocacy and flexibility. These are underpinned by nursing knowledge and clinical expertise contributing to an ability to work autonomously. These four projects demonstrate that research nurses in community-based research possess specific attributes which facilitate successful study development, implementation and outcome.

Okvat, Heather A; Zautra, Alex J

2011-06-01

The goal of this paper is to introduce community gardening as a promising method of furthering well-being and resilience on multiple levels: individual, social group, and natural environment. We examine empirical evidence for the benefits of gardening, and we advocate the development and testing of social ecological models of community resilience through examination of the impact of community gardens, especially in urban areas. The definition of community is extended beyond human social ties to include connections with other species and the earth itself, what Berry (1988) has called an Earth community. We discuss the potential contribution of an extensive network of community gardens to easing the global climate change crisis and address the role of community psychologists in community gardening research and policy-oriented action.

The role of nuclear energy in the European Community

The overall objective of the energy policy of the European Community is to achieve a secure supply of energy at reasonable cost and low environmental impact. This overall objective is embedded in the steps taken by the European Community towards the Single European Market. This subject will be addressed briefly, as well as the developments in Eastern Europe including the European Energy Charter. With regard to nuclear energy in the community, facts and issues related to electricity production, the front end and back end of the nuclear fuel cycle and current environmental and safety issues will be presented. A common industrial strategy is required in the community including safety regulations, technical specifications and products for international markets. Concerning safeguards, the Commission is fully committed to the obligations from Chapter VII of the Treaty and to any relevant international agreements concluded by the Community. This is reflected in the close cooperation of the Commission with the IAEA and in the increase of resources, both in staff and budget, which the Commission has allocated to the Safeguards Directorate to cope with the increasing requirements, for example for bulk handling facilities. Based on a request from the European Parliament, the Commission has issued in 1989 a first report on the operation of Euratom Safeguards. The Commission services are currently preparing the second report of this type. Finally, some remarks with regard to the future of nuclear energy and challenges of safeguards in the Community will be made

The extensive land use conversion expected to occur to meet demands for bioenergy feedstock production will likely have widespread impacts on agroecosystem biodiversity and ecosystem services, including carbon sequestration. Although arthropod detritivores are known to contribute to litter decomposition and thus energy flow and nutrient cycling in many plant communities, their importance in bioenergy feedstock communities has not yet been assessed. We undertook an experimental study quantifying rates of litter mass loss and nutrient cycling in the presence and absence of these organisms in three bioenergy feedstock crops-miscanthus (Miscanthus x giganteus), switchgrass (Panicum virgatum), and a planted prairie community. Overall arthropod abundance and litter decomposition rates were similar in all three communities. Despite effective reduction of arthropods in experimental plots via insecticide application, litter decomposition rates, inorganic nitrogen leaching, and carbon-nitrogen ratios did not differ significantly between control (with arthropods) and treatment (without arthropods) plots in any of the three community types. Our findings suggest that changes in arthropod faunal composition associated with widespread adoption of bioenergy feedstock crops may not be associated with profoundly altered arthropod-mediated litter decomposition and nutrient release. © 2012 Institute of Zoology, Chinese Academy of Sciences.

For many people living with HIV (PLHIV), disclosure or concealment of their HIV status may be under their personal control; however, for PLHIV with visible symptoms of their illness, disclosure may no longer be a choice. Previous research suggests that those with visible HIV symptoms have poorer mental and physical health than those without visible HIV symptoms. This study aimed to extend these findings and assess the role of perceived centrality of HIV in the lives of PLHIV as well as the role of attachment to an HIV-positive community in understanding the negative effects on health and well-being for PLHIV with visible HIV symptoms. Participants were 697 PLHIV who completed an online survey that assessed symptom visibility, HIV-status disclosure, perceived stigma, health and well-being, how central HIV was to identity and HIV community attachment. Results indicate that those with visible symptoms experienced more HIV-related stigma and had poorer outcomes on a range of psychological and mental health measures than those who were able to conceal their stigma. These effects remained after controlling for length of time since diagnosis, time on HIV treatment, perceived health satisfaction and age. PLHIV with visible symptoms also reported that HIV was more central to their identity and reported greater attachment to an HIV-positive community. Furthermore, findings suggest that while HIV centrality appears to increase the negative effects of having visible symptoms associated with HIV, greater community attachment seems to ameliorate these effects. This suggests the need for a nuanced understanding of the implications of visible HIV symptoms for PLHIV. The study also highlights the potential benefits of HIV-positive community attachment in buffering PLHIV from the negative effect of visible HIV symptoms on their health and well-being.

The new paradigm to pharmacy profession has changed the focus of pharmacists from product-centered to patient-oriented. This change has brought new set of beliefs and assumptions on the way services should be delivered to pharmacy clients. The main aim of this study was to explore the perception of community pharmacists on their current professional role in Dubai. Key findings show that community pharmacists are more directed toward business than patients. They almost dispense all categories of medicines over-the-counter without the need of prescriptions. However, a new trend of pharmacists in Dubai is to provide enhanced pharmacy services such as consultation to patients upon request.

The Role of Multicultural Media in Connecting Municipal Governments with Ethnocultural and Immigrant Communities: The Case of Ottawa

Directory of Open Access Journals (Sweden)

Luisa Veronis

2015-12-01

Full Text Available This paper aims to advance understanding of the role ethnic and multicultural media can play in connecting municipal governments and Ethnocultural and Immigrant Communities (EICs. Using an innovative mixed-methods approach and methodological triangulation, we compare the access to and use of multicultural media among four EICs—the Chinese, Latin American, Somali, and South Asian—in Ottawa, Canada. Our cross-comparative study yields three main findings: 1 members of participating communities proactively and strategically use a variety of sources to access information about local services; 2 noteworthy differences exist in the access to and use of different types of media both across and within the four EICs, due to demographic and cultural differences; and 3 participants shared challenges and opportunities that multicultural media afford to better connect municipal government and EICs. The paper’s findings make important empirical contributions to the literature on the integrative potential of ethnic and multicultural media by strengthening the reliability of data, validity of findings, and broadening and deepening understanding the role multicultural media play in promoting collaboration between city governments and diverse EICs.

Rowe, Timothy

1986-01-01

The pattern of translation activity in aeronautics and astronautics is reviewed. It is argued that the international nature of the aerospace industry and the commercialization of space have increased the need for the translation of scientific literature in the aerospace field. Various factors which can affect the quality of translations are examined. The need to translate the activities of the Soviets, Germans, and French in materials science in microgravity, of the Japanese, Germans, and French in the development of industrial ceramics, and of the Chinese in launching and communications satellites is discussed. It is noted that due to increases in multilateral and bilateral relationships in the aerospace industry, the amount of translation from non-English source material into non-English text will increase and the most important languages will be French and German, with an increasing demand for Japanese, Chinese, Spanish, and Italian translations.

Full Text Available Community-based mental health services are emphasized in the World Health Organization’s Mental Health Action Plan, the World Bank’s Disease Control Priorities, and the Action Plan of the World Psychiatric Association. There is increasing evidence for effectiveness of mental health interventions delivered by non-specialists in community platforms in low- and middle-income countries (LMIC. However, the role of community components has yet to be summarized. Our objective was to map community interventions in LMIC, identify competencies for community-based providers, and highlight research gaps. Using a review-of-reviews strategy, we identified 23 reviews for the narrative synthesis. Motivations to employ community components included greater accessibility and acceptability compared to healthcare facilities, greater clinical effectiveness through ongoing contact and use of trusted local providers, family involvement, and economic benefits. Locations included homes, schools, and refugee camps, as well as technology-aided delivery. Activities included awareness raising, psychoeducation, skills training, rehabilitation, and psychological treatments. There was substantial variation in the degree to which community components were integrated with primary care services. Addressing gaps in current practice will require assuring collaboration with service users, utilizing implementation science methods, creating tools to facilitate community services and evaluate competencies of providers, and developing standardized reporting for community-based programs.

The metabolic syndrome is a cluster of cardiovascular risk factors and its prevalence is alarmingly high in Kuwait, affecting nearly one third of the adult population. There is lack of information about the role of community pharmacists in the care of patients with the metabolic syndrome. To assess the awareness and opinions of community pharmacists about the metabolic syndrome and identify the services they provide for identification, management and monitoring of patients with the metabolic syndrome. Community pharmacies in Kuwait. A descriptive, cross-sectional study was performed on a randomly selected sample of 225 community pharmacists. Data were collected via face-to-face structured interview of the pharmacists using a pre-tested questionnaire. Pharmacists' knowledge and views on the metabolic syndrome, monitoring services provided, self-reported practices and perceived effectiveness of the various management interventions for the metabolic syndrome. The response rate was 97.8 %. Nine pharmacists claimed to know about the metabolic syndrome, but only one pharmacist could identify the condition correctly. After being given a definition of the metabolic syndrome, 67.7 % of respondents strongly agreed that its prevalence was rising in Kuwait. Nearly two thirds of respondents reported providing height and weight measurement service while 82.7 and 59.5 % of pharmacies provided blood pressure and blood glucose measurements, respectively. Waist circumference and lipid profile measurements were the least provided services (1.8 %). Respondents claimed to be involved in counseling patients on lifestyle modifications including increased exercise (98.1 %) and weight reduction through diet (96.9 %). Most pharmacists were involved in encouraging patients' adherence with prescribed treatments (98.6 %) and perceived these as the most effective intervention for the management of the metabolic syndrome (95.0 %). Respondents were less involved in monitoring patients' response

Full Text Available Forest benefit analysis is vital in ensuring sustainable community-based natural resources management. Forest depletion and degradation are key issues in rural Zimbabwe and strategies to enhance sustainable forest management are continually sought. This study was carried out to assess the impact of forests on communities from Nyanga, Guruve and Zvimba districts of Zimbabwe. It is based on a Big Lottery Fund project implemented by Progressio-UK and Environment Africa. Itfocuses on identifying replicable community forest and landmanagement strategies and the level of benefits accruing to the community. Analysis of change was based on the Income and Food Security and Forest benefits, which also constitutes the tools used during the research. The study confirms the high rate of deforestation and the increased realisation by communities to initiate practical measures aimed at protecting and sustaining forest and land resources from which they derive economic and social benefits. The results highlight the value of community structures (Farmer Field Schools and Environmental Action Groups as conduits for natural resource management. The interconnectivity among forests, agricultural systems and the integral role of people are recognised as key to climate change adaptation.

Community Health Workers (CHWs) have gained national recognition for their role in addressing health disparities and are increasingly integrated into the health care delivery system. There is a lack of consensus, however, regarding empirical evidence on the impact of CHW interventions on health outcomes. In this paper, we present results from the 2010 National Community Health Worker Advocacy Survey (NCHWAS) in an effort to strengthen a generalized understanding of the CHW profession that can be integrated into ongoing efforts to improve the health care delivery system. Results indicate that regardless of geographical location, work setting, and demographic characteristics, CHWs generally share similar professional characteristics, training preparation, and job activities. CHWs are likely to be female, representative of the community they serve, and to work in community health centers, clinics, community-based organizations, and health departments. The most common type of training is on-the-job and conference training. Most CHWs work with clients, groups, other CHWs and less frequently community leaders to address health issues, the most common of which are chronic disease, prevention and health care access. Descriptions of CHW activities documented in the survey demonstrate that CHWs apply core competencies in a synergistic manner in an effort to assure that their clients get the services they need. NCHWAS findings suggest that over the past 50 years, the CHW field has become standardized in response to the unmet needs of their communities. In research and practice, the field would benefit from being considered a health profession rather than an intervention.

Secure real-time wireless video streaming in the aeronautical telecommunications network

Czernik, Pawel; Olszyna, Jakub

2010-09-01

As Air Traffic Control Systems move from a voice only environment to one in which clearances are issued via data link, there is a risk that an unauthorized entity may attempt to masquerade as either the pilot or controller. In order to protect against this and related attacks, air-ground communications must be secured. The challenge is to add security in an environment in which bandwidth is limited. The Aeronautical Telecommunications Network (ATN) is an enabling digital network communications technology that addresses capacity and efficiency issues associated with current aeronautical voice communication systems. Equally important, the ATN facilitates migration to free flight, where direct computer-to-computer communication will automate air traffic management, minimize controller and pilot workload, and improve overall aircraft routing efficiency. Protecting ATN communications is critical since safety-of-flight is seriously affected if an unauthorized entity, a hacker for example, is able to penetrate an otherwise reliable communications system and accidentally or maliciously introduce erroneous information that jeopardizes the overall safety and integrity of a given airspace. However, an ATN security implementation must address the challenges associated with aircraft mobility, limited bandwidth communication channels, and uninterrupted operation across organizational and geopolitical boundaries. This paper provides a brief overview of the ATN, the ATN security concept, and begins a basic introduction to the relevant security concepts of security threats, security services and security mechanisms. Security mechanisms are further examined by presenting the fundamental building blocks of symmetric encipherment, asymmetric encipherment, and hash functions. The second part of this paper presents the project of cryptographiclly secure wireless communication between Unmanned Aerial Vehicles (UAV) and the ground station in the ATM system, based on the ARM9 processor

Full Text Available Social network play an important role in both the decision to emigrate and the choice of location. Related to migrants and its social net, very little is known about patterns of integration and community participation in rural and low population density contexts in Spain. This article explores these issues and is based on a study, in the province of Teruel (Spain, using a sample of 324 Latin American migrants over the age of 18, selected by sex and place of residence. A standardised test - the Musitu and Gracia AC-90 Community Social Support Questionnaire and open questions were employed. ANOVAS analysis showed significant differences in community integration and participation in accordance with socioeconomic, motivational and social interaction variables.

Arbuscular fungi have a major role in directing the functioning of terrestrial ecosystems yet little is known about their biogeographical distribution. The Baas-Becking hypothesis ('everything is everywhere, but, the environment selects') was tested by investigating the distribution of arbuscular mycorrhizal fungi (AMF) at the landscape scale and the influence of environmental factors and geographical distance in determining community composition. AMF communities in Trifolium repens and Lolium perenne roots were assessed in 40 geographically dispersed sites in Ireland representing different land uses and soil types. Field sampling and laboratory bioassays were used, with AMF communities characterised using 18S rRNA terminal-restriction fragment length polymorphism. Landscape-scale distribution of AMF was driven by the local environment. AMF community composition was influenced by abiotic variables (pH, rainfall and soil type), but not land use or geographical distance. Trifolium repens and L. perenne supported contrasting communities of AMF, and the communities colonising each plant species were consistent across pasture habitats and over distance. Furthermore, L. perenne AMF communities grouped by soil type within pasture habitats. This is the largest and most comprehensive study that has investigated the landscape-scale distribution of AMF. Our findings support the Baas-Becking hypothesis at the landscape scale and demonstrate the strong influence the local environment has on determining AMF community composition.

Routines of Riparian Women of the Amazon Region: Activities and Roles in the Family, at Work and in the Community

Directory of Open Access Journals (Sweden)

Neuzeli Maria de Almeida Pinto

2015-12-01

Full Text Available The aim of this study was to investigate the perception of the routines of women who live in Amazon riverside communities, identifying the roles and activities related to domestic work, açaí gathering and actions in community associations. The participants were three women from two island communities in Belem, Ilha Grande and Combu, who earn their living solely from açaí gathering, work at home and in community associations. The instruments used were the sociodemographic schedule (ISD, the Inventory of Routine (IR and Field Diary (DC. All activities are defined by gender. Although riparian women follow the rigid family concepts of gender division in regards to labor, the participation women in paid professional activities, in this case, açaí gathering, has increased. The woman’s place in riparian family structure is considered dynamic and encompasses a cluster of systems that maintain interdependent relationships. In this sense, the context acts as a facilitator for development, producing constancy and change in the characteristics of riverside women and during the course of her life, family and community.

The Value of Identifying and Recovering Lost GN&C Lessons Learned: Aeronautical, Spacecraft, and Launch Vehicle Examples

Dennehy, Cornelius J.; Labbe, Steve; Lebsock, Kenneth L.

2010-01-01

Within the broad aerospace community the importance of identifying, documenting and widely sharing lessons learned during system development, flight test, operational or research programs/projects is broadly acknowledged. Documenting and sharing lessons learned helps managers and engineers to minimize project risk and improve performance of their systems. Often significant lessons learned on a project fail to get captured even though they are well known 'tribal knowledge' amongst the project team members. The physical act of actually writing down and documenting these lessons learned for the next generation of NASA GN&C engineers fails to happen on some projects for various reasons. In this paper we will first review the importance of capturing lessons learned and then will discuss reasons why some lessons are not documented. A simple proven approach called 'Pause and Learn' will be highlighted as a proven low-impact method of organizational learning that could foster the timely capture of critical lessons learned. Lastly some examples of 'lost' GN&C lessons learned from the aeronautics, spacecraft and launch vehicle domains are briefly highlighted. In the context of this paper 'lost' refers to lessons that have not achieved broad visibility within the NASA-wide GN&C CoP because they are either undocumented, masked or poorly documented in the NASA Lessons Learned Information System (LLIS).

Role of community pharmacists in asthma – Australian research highlighting pathways for future primary care models

Directory of Open Access Journals (Sweden)

Saini B

2011-04-01

Full Text Available Asthma is one of the most common chronic conditions affecting the Australian population. Amongst primary healthcare professionals, pharmacists are the most accessible and this places pharmacists in an excellent position to play a role in the management of asthma. Globally, trials of many community pharmacy-based asthma care models have provided evidence that pharmacist delivered interventions can improve clinical, humanistic and economic outcomes for asthma patients. In Australia, a decade of coordinated research efforts, in various aspects of asthma care, has culminated in the implementation trial of the Pharmacy Asthma Management Service (PAMS, a comprehensive disease management model. There has been research investigating asthma medication adherence through data mining, ways in which usual asthma care can be improved. Our research has focused on self-management education, inhaler technique interventions, spirometry trials, interprofessional models of care, and regional trials addressing the particular needs of rural communities. We have determined that inhaler technique education is a necessity and should be repeated if correct technique is to be maintained. We have identified this effectiveness of health promotion and health education, conducted within and outside the confines of the pharmacy, in public for a and settings such as schools, and established that this outreach role is particularly well received and increases the opportunity for people with asthma to engage in their asthma management. Our research has identified that asthma patients have needs which pharmacists delivering specialized models of care, can address. There is a lot of evidence for the effectiveness of asthma care by pharmacists, the future must involve integration of this role into primary care.

Cefixime is an oral third generation cephalosporin, frequently used in respiratory tract infections (RTI) in the pediatric population. However, in some publications cefixime has demonstrated poor efficacy against staphylococci and streptococci. of this study was to evaluate the efficacy of cefixime in the treatment of community-acquired infections in a country where parenteral third generation cephalosporins have been used for a long time. The present study was designed to assess the clinical efficacy, bacteriological eradication rates and tolerability of cefixime in children with community-acquired upper RTI (URTI), lower RTI (LRTI) and uncomplicated urinary tract infections (UTI). The study was prospective, open, and included 89 patients, from 6 months to 28 years, of both sexes, with the diagnosis of community-acquired URTI, LRTI and UTI. The treatment with cefixime was successful in 30/30 (100%) patients suffering from acute otitis media (AOM), in 10/12 (83.3%) with acute sinusitis, in 12/12 patients (100%) with pneumonia, in 31/35 (88.57) with uncomplicated UTI. The antibiotic was well tolerated. In 10 days treatment we recorded one case (1.3%) with acute gastroenteritis and two cases (2.6%) of maculopapular rash. Side-effects were transient and disappeared after finishing therapy in all three of the cases. Community-acquired infections, such as AOM, LRTI and UTI, caused by susceptible pathogens, can be treated with cefixime, as a good choice for a successful clinical response.

Evidence linking home hazards to falls has not been well established. Falls and fall injury are a major public health concern for the elderly. Fall of elderly is very much affected by environmental hazards. Falls are a major cause of morbidity and mortality in persons older than 60. There is a greater-than-linear increase in the rate of falls with environmental hazards. This cross section survey will not only lay the foundation for further study on this topic but also provide the basis for the development of preventive program of falls for the elders of Pakistan. Objective: To explore the role of environmental hazards of fall in the community dwelling elders is the area which is lacking in research. Methods: This cross sectional study was conducted from October to December 2010 in Lahore and its peripheries and also the patients in hospital settings come after fractures or fall injuries. The total number of people included was 100. Community dwelling Elders above 60 years having recent history of at least one fall were included regardless of gender. The data were entered and analyzed using SPSS 11.5. Results: There were 71 people out of 100 who fell inside the home, 10 fell outside the home and 18 were not applicable to this question. There were 19% people, who fell repeatedly at one place, 31 people replied about hazard environment where fallen that contribute to fall. According to 24 people they had Safety checks of their home yard and/ or neighborhood which will assist to avoid future fall. Conclusion: Most elderly persons live in a risky home setting. It is vital that environmental hazard be recognized and removed for wellbeing of elderly. (author)

2018-03-01

Medication reviews by community pharmacists are an increasingly common strategy to improve medication management for chronic conditions, and are part of wider efforts to make more effective use of community-based health professionals. To identify opportunities to optimize the medication review program in Ontario, Canada, we explored how providers and clients interpret and operationalize medication reviews within everyday community pharmacy practice. We conducted a qualitative ethnographic study at four pharmacies in Ontario, Canada, including non-participant observation of provider and client activities and interactions with specific attention to medication reviews, as well as brief ethnographic interviews with providers and clients, and in-depth, semi-structured interviews with providers. We report on 72h of field research, observation of 178 routine pharmacist-client interactions and 29 medication reviews, 62 brief ethnographic interviews with providers and clients, and 7 in-depth, semi-structured interviews with providers. We found that medication reviews were variably conducted across the dimensions of duration, provider type, location, and interaction style, and that local contexts and system-wide developments influence their meaning and practice. Medication reviews are exemplary of policy efforts to enhance the role of community pharmacies within health systems and the scope of practice of pharmacists as healthcare professionals. Our study highlights the importance of the local structure of community pharmacy practice and the clinical aspirations of pharmacists in the delivery of medication reviews.

Roles of Arbuscular Mycorrhizal Fungi and Soil Abiotic Conditions in the Establishment of a Dry Grassland Community.

Directory of Open Access Journals (Sweden)

Jana Knappová

Full Text Available The importance of soil biota in the composition of mature plant communities is commonly acknowledged. In contrast, the role of soil biota in the early establishment of new plant communities and their relative importance for soil abiotic conditions are still poorly understood.The aim of this study was to understand the effects of soil origin and soil fungal communities on the composition of a newly established dry grassland plant community. We used soil from two different origins (dry grassland and abandoned field with different pH and nutrient and mineral content. Grassland microcosms were established by sowing seeds of 54 species of dry grassland plants into the studied soils. To suppress soil fungi, half of the pots were regularly treated with fungicide. In this way, we studied the independent and combined effects of soil origin and soil community on the establishment of dry grassland communities.The effect of suppressing the soil fungal community on the richness and composition of the plant communities was much stronger than the effect of soil origin. Contrary to our expectations, the effects of these two factors were largely additive, indicating the same degree of importance of soil fungal communities in the establishment of species-rich plant communities in the soils from both origins. The negative effect of suppressing soil fungi on species richness, however, occurred later in the soil from the abandoned field than in the soil from the grassland. This result likely occurred because the negative effects of the suppression of fungi in the field soil were caused mainly by changes in plant community composition and increased competition. In contrast, in the grassland soil, the absence of soil fungi was limiting for plants already at the early stages of their establishment, i.e., in the phases of germination and early recruitment. While fungicide affects not only arbuscular mycorrhizal fungi but also other biota, our data indicate that changes

There is an extensive body of literature on community-based participatory research (CBPR) and the role of community-academic partnerships, much of which has involved community partners in the conceptualization and preparation of publications. However, there has been a relative dearth of solely community voices addressing these topics, given the other roles and responsibilities which community members and leaders of community-based organizations (CBOs) have. The purpose of this article is to share the perspectives of three long-time (>20 years) community partners involved in the Detroit Community-Academic Urban Research Center and its affiliated partnerships. In this article, we community partners provide our assessment of the benefits and challenges in using a CBPR approach at the personal, organizational, and community levels; the factors that facilitate effective partnerships; and our lessons learned through engagement in CBPR. We also present specific recommendations from a community perspective to researchers and institutions interested in conducting CBPR.

Most of developing countries give further consideration to include entrepreneurship as an agenda to help the poor to increase the living standard. In fact, entrepreneurship offers various business opportunities for rural communities to achieve better quality of life. However, the crucial part of doing business is to recognize business opportunity. Entrepreneurship and opportunity are two terms that complement each other. Opportunity recognition enables the entrepreneur to identify a good idea and transform it into a business concept. The purpose of this study is to examine the relationship between attitude (attitude toward money, attitude toward start-up and entrepreneurial intention. This paper also intends to understand the role of entrepreneurial opportunity recognition as a mediator between attitude and entrepreneurial intention. The aim of this research is to support training providers, to identify input for entrepreneurial training, specifically developing business concepts among rural community. From the practical perspective, it might help the government to understand the necessity to encourage entrepreneurial movement among rural community as to ensure business ideas flow. This research employed the quantitative method of data collection. The questionnaires were distributed to 500 local populations according to districts and villages. The findings of this study showed that both attitude (attitude toward money, attitude toward start-up influence entrepreneurial intention. The relationship between attitude toward start-up and entrepreneurial intention was mediated by opportunity recognition.

Nowadays, smart composites based on different nano-scale carbon fillers, such as carbon nanotubes (CNTs), are increasingly being thought of as a more possible alternative solution to conventional smart materials, mainly for their improved electrical properties. Great attention is being given by the research community in designing highly sensitive strain sensors for more and more ambitious challenges: in such context, interest fields related to carbon nanotubes have seen extraordinary development in recent years. The authors aim to provide the most contemporary overview possible of carbon nanotube-based strain sensors for aeronautical application. A smart structure as a morphing wing needs an embedded sensing system in order to measure the actual deformation state as well as to "monitor" the structural conditions. Looking at more innovative health monitoring tools for the next generation of composite structures, a resin strain sensor has been realized. The epoxy resin was first analysed by means of a micro-tension test, estimating the electrical resistance variations as function of the load, in order to demonstrate the feasibility of the sensor. The epoxy dogbone specimen has been equipped with a standard strain gauge to quantify its strain sensitivity. The voltamperometric tests highlight a good linearity of the electrical resistance value as the load increases at least in the region of elastic deformation of the material. Such intrinsic piezoresistive performance is essentially attributable to the re-arrangement of conductive percolating network formed by MWCNT, induced by the deformation of the material due to the applied loads. The specimen has been prepared within this investigation, to demonstrate its performance for a future composite laminate typical of aerospace structures. The future carbon-fiber sensor can replace conventional metal foil strain gauges in aerospace applications. Furthermore, dynamic tests will be carried out to detect any non

The Role of Heterotrophic Microbial Communities in Estuarine C Budgets and the Biogeochemical C Cycle with Implications for Global Warming: Research Opportunities and Challenges.

Estuaries are among the most productive and economically important marine ecosystems at the land-ocean interface and contribute significantly to exchange of CO2 with the atmosphere. Estuarine microbial communities are major links in the biogeochemical C cycle and flow of C in food webs from primary producers to higher consumers. Considerable attention has been given to bacteria and autotrophic eukaryotes in estuarine ecosystems, but less research has been devoted to the role of heterotrophic eukaryotic microbes. Current research is reviewed here on the role of heterotrophic eukaryotic microbes in C biogeochemistry and ecology of estuaries, with particular attention to C budgets, trophodynamics, and the metabolic fate of C in microbial communities. Some attention is given to the importance of these processes in climate change and global warming, especially in relation to sources and sinks of atmospheric CO2 , while also documenting the current paucity of research on the role of eukaryotic microbes that contribute to this larger question of C biogeochemistry and the environment. Some recommendations are made for future directions of research and opportunities of applying newer technologies and analytical approaches to a more refined analysis of the role of C in estuarine microbial community processes and the biogeochemical C cycle. © 2015 The Author Journal of Eukaryotic Microbiology © 2015 International Society of Protistologists.

Piloting the role of a pharmacist in a community palliative care multidisciplinary team: an Australian experience

Full Text Available Abstract Background While the home is the most common setting for the provision of palliative care in Australia, a common problem encountered here is the inability of patient/carers to manage medications, which can lead to misadventure and hospitalisation. This can be averted through detection and resolution of drug related problems (DRPs by a pharmacist; however, they are rarely included as members of the palliative care team. The aim of this study was to pilot a model of care that supports the role of a pharmacist in a community palliative care team. A component of the study was to develop a cost-effective model for continuing the inclusion of a pharmacist within a community palliative care service. Methods The study was undertaken (February March 2009-June 2010 in three phases. Development (Phase 1 involved a literature review; scoping the pharmacist's role; creating tools for recording DRPs and interventions, a communication and education strategy, a care pathway and evidence based patient information. These were then implemented in Phase 2. Evaluation (Phase 3 of the impact of the pharmacist's role from the perspectives of team members was undertaken using an online survey and focus group. Impact on clinical outcomes was determined by the number of patients screened to assess their risk of medication misadventure, as well as the number of medication reviews and interventions performed to resolve DRPs. Results The pharmacist screened most patients (88.4%, 373/422 referred to the palliative care service to assess their risk of medication misadventure, and undertook 52 home visits. Medication reviews were commonly conducted at the majority of home visits (88%, 46/52, and a variety of DRPs (113 were detected at this point, the most common being "patient requests drug information" (25%, 28/113 and "condition not adequately treated" (22%, 25/113. The pharmacist made 120 recommendations in relation to her interventions. Fifty percent of online

Community pharmacists (CPs) have been changing their role to focus on patient-centred services to improve the quality of chronic disease management (CDM) in primary care. However, CPs have not been readily included in collaborative CDM with other primary care professionals such as physicians. There is little understanding of the CP role change and whether it affects the utilisation of CPs in primary care collaborative CDM. To explore physician and CP perceptions of the CP's role in Australian primary care and how these perceptions may influence the quality of physician/CP CDM programmes. Data were collected from physicians and CPs using semi-structured interviews. A qualitative methodology utilising thematic analysis was employed during data analysis. Qualitative methodology trustworthiness techniques, negative case analysis and member checking were utilised to substantiate the resultant themes. A total of 22 physicians and 22 CPs were interviewed. Strong themes emerged regarding the participant perceptions of the CP's CDM role in primary care. The majority of interviewed physicians perceived that CPs did not have the appropriate CDM knowledge to complement physician knowledge to provide improved CDM compared with what they could provide on their own. Most of the interviewed CPs expressed a willingness and capability to undertake CDM; however, they were struggling to provide sustainable CDM in the business setting within which they function in the primary care environment. Role theory was selected as it provided the optimum explanation of the resultant themes. First, physician lack of confidence in the appropriateness of CP CDM knowledge causes physicians to be confused about the role CPs would undertake in a collaborative CDM that would benefit the physicians and their patients. Thus, by increasing physician awareness of CP CDM knowledge, physicians may see CPs as suitable CDM collaborators. Second, CPs are experiencing role conflict and stress in trying to change

2006-09-01

Full Text Available Abstract Background A Community health assessment (CHA involves the use of Geographic Information Systems (GIS in conjunction with other software to analyze health and population data and perform numerical-spatial problem solving. There has been little research on identifying how public health professionals integrate this software during typical problem solving scenarios. A better understanding of this is needed to answer the "What" and the "How". The "What" identifies the specific software being used and the "How" explains the way they are integrated together during problem solving steps. This level of understanding will highlight the role of GIS utilization during problem solving and suggest to developers how GIS can be enhanced to better support data analysis during community health assessment. Results An online survey was developed to identify the information technology used during CHA analysis. The tasks were broken down into steps and for our analysis these steps were categorized by action: Data Management/Access, Data Navigation, Geographic Comparison, Detection of Spatial Boundaries, Spatial Modelling, and Ranking Analysis. 27 CHA professionals completed the survey, with the majority of participants (14 being from health departments. Statistical software (e.g. SPSS was the most popular software for all but one of the types of steps. For this step (detection of spatial boundaries, GIS was identified as the most popular technology. Conclusion Most CHA professionals indicated they use statistical software in conjunction with GIS. The statistical software appears to drive the analysis, while GIS is used primarily for simple spatial display (and not complex spatial analysis. This purpose of this survey was to thoroughly examine into the process of problem solving during community health assessment data analysis and to gauge how GIS is integrated with other software for this purpose. These findings suggest that GIS is used more for spatial

The factors that determine plant community resistance to exotic annual Bromus species (Bromushereafter) are diverse and context specific. They are influenced by the environmental characteristics and attributes of the community, the traits of Bromus species, and the direct and indirect interactions of Bromus with the plant community. Environmental factors, in particular ambient and soil temperatures, have significant effects on the ability of Bromus to establish and spread. Seasonality of precipitation relative to temperature influences plant community resistance toBromus through effects on soil water storage, timing of water and nutrient availability, and dominant plant life forms. Differences among plant communities in how well soil resource use by the plant community matches resource supply rates can influence the magnitude of resource fluctuations due to either climate or disturbance and thus the opportunities for invasion. The spatial and temporal patterns of resource availability and acquisition of growth resources by Bromus versus native species strongly influence resistance to invasion. Traits of Bromus that confer a “priority advantage” for resource use in many communities include early-season germination and high growth and reproductive rates. Resistance to Bromus can be overwhelmed by high propagule supply, low innate seed dormancy, and large, if short-lived, seed banks. Biological crusts can inhibit germination and establishment of invasive annual plants, including several annual Bromus species, but are effective only in the absence of disturbance. Herbivores can have negative direct effects on Bromus, but positive indirect effects through decreases in competitors. Management strategies can be improved through increased understanding of community resistance to exotic annual Bromus species.

Multifaceted Role of Pneumolysin in the Pathogenesis of Myocardial Injury in Community-Acquired Pneumonia

Directory of Open Access Journals (Sweden)

Ronald Anderson

2018-04-01

Full Text Available Pneumolysin (PLY, a member of the family of Gram-positive bacterial, cholesterol-dependent, β-barrel pore-forming cytolysins, is the major protein virulence factor of the dangerous respiratory pathogen, Streptococcus pneumoniae (pneumococcus. PLY plays a major role in the pathogenesis of community-acquired pneumonia (CAP, promoting colonization and invasion of the upper and lower respiratory tracts respectively, as well as extra-pulmonary dissemination of the pneumococcus. Notwithstanding its role in causing acute lung injury in severe CAP, PLY has also been implicated in the development of potentially fatal acute and delayed-onset cardiovascular events, which are now recognized as being fairly common complications of this condition. This review is focused firstly on updating mechanisms involved in the immunopathogenesis of PLY-mediated myocardial damage, specifically the direct cardiotoxic and immunosuppressive activities, as well as the indirect pro-inflammatory/pro-thrombotic activities of the toxin. Secondly, on PLY-targeted therapeutic strategies including, among others, macrolide antibiotics, natural product antagonists, cholesterol-containing liposomes, and fully humanized monoclonal antibodies, as well as on vaccine-based preventive strategies. These sections are preceded by overviews of CAP in general, the role of the pneumococcus as the causative pathogen, the occurrence and types of CAP-associated cardiac complication, and the structure and biological activities of PLY.

Community resiliency is a theoretical framework useful for describing the process used by communities to address adversity. A mixed-method 2-year case study was conducted to gather information about community resiliency in 2 rural communities. This article focuses on the themes generated from qualitative interviews with 55 members of these communities. The participants viewed community as a place of interdependence and interaction. The majority saw community resiliency as the ability to address challenges. Characteristics included physical and social infrastructure, population characteristics, conceptual characteristics, and problem-solving processes. Barriers included negative individual attitudes and lack of infrastructure in rural communities. Nurses could play a key role in enhancing the resiliency of rural communities by developing and implementing programs based on the Community Resiliency Model, which was supported in this study.

Community health workers are reemerging as an essential component of health systems in low-income countries. However, there are concerns that unless they are adequately supported, their motivation and performance will be suboptimal. mHealth presents an opportunity to improve support for community health workers; however, most interventions to date have been designed through a top-down approach, rarely involve the end user, and have not focused on motivation. To use formative research to explore the views of community health workers in Uganda and Mozambique on the potential role of mHealth in their work delivering integrated community case management of children. We conducted 24 in-depth interviews and 5 focus group discussions with community health workers in Uganda and Mozambique. Data were collected on: current phone use, preferred phone and charger characteristics, and perceptions of a range of potential mHealth interventions. Interviews were conducted in the local language, were audio recorded and converted into expanded notes. Interviews were coded for key thematic areas using both deductive and inductive codes. Deductive codes included mHealth's potential impact on motivation and performance. The most salient roles of mHealth in improving performance and motivation were reducing the need for travel, improving efficiency and planning, receiving feedback and information, and improving communication with supervisors and other community health workers. This was mostly through improved voice and short message service (SMS) text communication. Specific components of mHealth interventions that participants felt could improve motivation included increasing their visibility and credibility through branding of phones; providing an SMS response to data submission; and sending SMS messages about the importance of their work and achievements, rather than just reminders or technical messages. Participants identified feasibility issues related to the language of SMS

Witnessed community violence has been linked to a number of internalizing and externalizing problems in adolescents. Guided by Cicchetti and Lynch's (1993) ecological-transactional model, this study aimed to examine the impact that family-level factors had on negative outcomes associated with witnessed community violence. Using a nationally representative sample, we explored the moderational role of family cohesion in the relationship between witnessing community violence and delinquent behavior while taking demographic variables into account. Results from the investigation suggested that low levels of family cohesion were predictive of delinquency after controlling for race, gender, past delinquency, and direct trauma. In addition, the findings suggested that family cohesion moderated the impact of witnessed community violence on future delinquent behavior. Future directions for research and implications for practice were also discussed.

In aerospace industry, the structure of the aircraft is assembled using small parts or a combination of them that are made with different materials, such as for instance aluminium, titanium, composites or even 3D printed parts. The union between these small parts is a critical point for the integrity of the aircraft. The quality of this union will decide the fatigue of adjacent components and therefore the useful life of them. For the union process the most extended method is the rivets, mainly because their low cost and easy manufacturing. For this purpose it is necessary to made drill holes in the aeronautical surface to insert the rivets. In this contribution, we present the preliminary results of a 3D inspection system [1] for drill holes analysis in aeronautical surfaces. The system, based in optical triangulation, was developed by the Group of Optoelectronic Image Processing from the University of Valencia in the framework of the Airbus Defence and Space (AD&S), MINERVA project (Manufacturing industrial - means emerging from validated automation). The capabilities of the system permits to generate a point cloud with 3D information and GD&T (geometrical dimensions and tolerances) characteristics of the drill hole. For the inner surface defects detection, the system can generate an inner image of the drill hole with a scaled axis to obtain the defect position. In addition, we present the analysis performed for the drills in the wing station of the A-400 M. In this analysis the system was tested for diameters in the range of [10 - 15.96] mm, and for Carbon Fibre.

Quorum sensing (QS) signalling has been extensively studied in single species populations. However, the ecological role of QS in complex, multi-species communities, particularly in the context of community assembly, has neither been experimentally explored nor theoretically addressed. Here, we performed a long-term bioreactor ecology study to address the links between QS, organization and composition of complex microbial communities. The conversion of floccular biomass to highly structured granules was found to be non-random, but strongly and positively correlated with N-acyl-homoserine-lactone (AHL)-mediated QS. Specific AHLs were elevated up to 100-fold and were strongly associated with the initiation of granulation. Similarly, the levels of particular AHLs decreased markedly during the granular disintegration phase. Metadata analysis indicated that granulation was accompanied by changes in extracellular polymeric substance (EPS) production and AHL add-back studies also resulted in increased EPS synthesis. In contrast to the commonly reported nanomolar to micromolar signal concentrations in pure culture laboratory systems, QS signalling in the granulation ecosystem occurred at picomolar to nanomolar concentrations of AHLs. Given that low concentrations of AHLs quantified in this study were sufficient to activate AHL bioreporters in situ in complex granular communities, AHL mediated QS may be a common feature in many natural and engineered ecosystems, where it coordinates community behaviour.

The year of 1999 to airline companies was exactly a year when they had to tackle the Y2K issue all the time with no introduction of new model planes. For the purpose of much appealing for aeronautical safety, the government and private companies jointly made a demonstration flight simulating the shift to a new year in September. The persons concerned in the Civil Aviation Bureau, the Ministry of Transport, mass communication, and airline companies were on the flight. The demonstration flight was finished with no big troubles. The standard weight of passengers, etc. which is used for weight/gravity center position management of airliners was to be newly set. Following the domestic line in 1998, the standard weight of the international line was set in 1999. As a new flight system, RVSM flight is planned to be started in the Pacific air area in February 2000. In the RVSM flight, airplane is flown by shortening vertical control intervals from 2000ft to 1000ft at the altitude between 29,000ft and 41,000ft. In 1999, domestic airline companies decided on no smoking at all the seats in both the domestic line and international line. (NEDO)

Trichodesmium is a globally distributed cyanobacterium whose nitrogen-fixing capability fuels primary production in warm oligotrophic oceans. Like many photoautotrophs, Trichodesmium serves as a host to various other microorganisms, yet little is known about how this associated community modulates fluxes of environmentally relevant chemical species into and out of the supraorganismal structure. Here, we utilized metatranscriptomics to examine gene expression activities of microbial communities associated with Trichodesmium erythraeum (strain IMS101) using laboratory-maintained enrichment cultures that have previously been shown to harbor microbial communities similar to those of natural populations. In enrichments maintained under two distinct CO 2 concentrations for ∼8 years, the community transcriptional profiles were found to be specific to the treatment, demonstrating a restructuring of overall gene expression had occurred. Some of this restructuring involved significant increases in community respiration-related transcripts under elevated CO 2 , potentially facilitating the corresponding measured increases in host nitrogen fixation rates. Particularly of note, in both treatments, community transcripts involved in the reduction of nitrate, nitrite, and nitrous oxide were detected, suggesting the associated organisms may play a role in colony-level nitrogen cycling. Lastly, a taxon-specific analysis revealed distinct ecological niches of consistently cooccurring major taxa that may enable, or even encourage, the stable cohabitation of a diverse community within Trichodesmium consortia. IMPORTANCE Trichodesmium is a genus of globally distributed, nitrogen-fixing marine cyanobacteria. As a source of new nitrogen in otherwise nitrogen-deficient systems, these organisms help fuel carbon fixation carried out by other more abundant photoautotrophs and thereby have significant roles in global nitrogen and carbon cycling. Members of the Trichodesmium genus tend to

Topousis, Daria E.; Dennehy, Cornelius J.; Lebsock, Kenneth L.

2011-01-01

Historically, engineers at the National Aeronautics and Space Administration (NASA) had few opportunities or incentives to share their technical expertise across the Agency. Its center- and project- focused culture often meant that knowledge never left organizational and geographic boundaries. With increasingly complex missions, the closeout of the Shuttle Program, and a new generation entering the workforce, developing a knowledge sharing culture became critical. To address this need, the Office of the Chief Engineer established communities of practice on the NASA Engineering Network. These communities were strategically aligned with NASA's core competencies in such disciplines as avionics, flight mechanics, life support, propulsion, structures, loads and dynamics, human factors, and guidance, navigation, and control. This paper describes the process used to identify and develop communities, from establishing simple websites that compiled discipline-specific resources to fostering a knowledge-sharing environment through collaborative and interactive technologies. It includes qualitative evidence of improved availability and transfer of knowledge. It focuses on pivotal capabilities that increased knowledge exchange such as a custom-made Ask An Expert system, community contact lists, publication of key resources, and submission forms that allowed any user to propose content for the sites. It discusses the peer relationships that developed through the communities and the leadership and infrastructure that made them possible.

Transitions of care (TOC) refer to the movement of patients across institutions, among providers, between different levels of care, and to and from home. Medication errors that occur during TOC have the potential to result in medical complications that are serious for the patient and costly to the health care system. Positive outcomes have been demonstrated when pharmacists are involved in providing TOC services, including reducing preventable adverse drug reactions, medication-related problems, and rehospitalizations, as well as improving the discharge process. This review explores TOC models involving community pharmacy practice, the current impact of pharmacist interventions in TOC, and patient satisfaction with TOC services provided by community pharmacists. Common barriers and potential solutions to TOC services provided in the community pharmacy, such as patient identification, information gathering, standardization of services, administrative support, reimbursement, and time restraints, are also discussed.

Malaria is endemic in Nigeria, with significant records of mortality and morbidity. Adequate community involvement is central to a successful implementation of malaria control programs. This study assessed the effects of a training programme on knowledge of malaria prevention and control among community role model care givers. A descriptive cross sectional study of a pre-and post-test design method was conducted among 400 eligible community members in Osun State. Training was given in the form of organized lectures, health education and practical demonstration sessions. Scores of pre-test and post-test conducted after four months interval were compared. Multistage sampling method was adopted in selecting study participants, while data was analyzed using the SPSS software version 17.0. Mean age was 43.8 (±1.4) years. Average knowledge score of cause, transmission, risk factors and consequences, awareness of common symptoms and preventive practices improved during post-training test when compared with pr-training test. The overall descriptive mean knowledge score in pre-test and post-test were 2.1 and 3.5 respectively out of an average maximum score of 5.0, giving an increment of 66.7%. Role model care givers with formal education were twice and three times more likely to know about disease 'transmission' (OR 1.9, 95%CI 0.11-0.19, p=0.002) and 'consequences' (OR 2.9, 95%CI 0.25-0.65, p=0.040) respectively compared to those without formal education. Training on malaria improved the knowledge of malaria prevention and control among role model community care givers towards a successful implementation of malaria control programmes.

Leonhardt, Kathryn Kraft

2010-01-01

Community engagement is widely endorsed but poorly defined as a strategy to improve patient safety. With strong evidence that engaging patients can positively influence health outcomes, it is presumed that community engagement could improve patient safety. Leaning on the models from other disciplines such as public health, the adequate knowledge and application of the principles of community engagement are critical for this approach to be effective. This article provides a description of the theories supporting patient partnership and community engagement, reviews critical elements of successful community-based programs, and identifies the potential for empowering communities to improve patient safety.

To better understand the beliefs of men and women in western Kenya regarding the appropriate role of men in maternal health and to identify barriers to greater involvement. Between June 1 and July 31, 2014, a cross-sectional qualitative study enrolled lay men, lay women, and community health workers from Kisumu and Nyamira counties in western Kenya. Semi-structured focus group discussions were conducted and qualitative approaches were utilized to analyze the transcripts and identify common themes. In total, 134 individuals participated in 18 focus group discussions. Participants discussed the role of men and a general consensus was recorded that it was a man's duty to protect women during pregnancy. When discussing obstacles to male involvement, female participants highlighted gender dynamics and male participants raised financial limitations. There was considerable discrepancy between how men described their roles and how they actually behaved, although educated men appeared to describe themselves as performing more supportive behaviors compared with male participants with less education. It is suggested that interventions aimed at increasing male involvement should incorporate the existing culturally sanctioned roles men perform as a foundation upon which to build, rather than attempting to construct roles that oppose prevailing norms.

Accurate knowledge and understanding of data link traffic loads that will have an impact on the underlying communications infrastructure within the National Airspace System (NAS) is of paramount importance for planning, development and fielding of future airborne and ground-based communications systems. Attempting to better understand this impact, NASA Glenn Research Center (GRC), through its contractor Computer Networks & Software, Inc. (CNS, Inc.), has developed an emulation and test facility known as the Virtual Aircraft and Controller (VAC) to study data link interactions and the capacity of the NAS to support Controller Pilot Data Link Communications (CPDLC) traffic. The drawback of the current VAC test bed is that it does not allow the test personnel and researchers to present a real world RF environment to a complex airborne or ground system. Fortunately, the United States Air Force and Navy Avionics Test Commands, through its contractor ViaSat, Inc., have developed the Joint Communications Simulator (JCS) to provide communications band test and simulation capability for the RF spectrum through 18 GHz including Communications, Navigation, and Identification and Surveillance functions. In this paper, we are proposing the development of a new and robust test bed that will leverage on the existing NASA GRC's VAC and the Air Force and Navy Commands JCS systems capabilities and functionalities. The proposed NASA Glenn Research Center's Aeronautical Networks Research Simulator (ANRS) will combine current Air Traffic Control applications and physical RF stimulation into an integrated system capable of emulating data transmission behaviors including propagation delay, physical protocol delay, transmission failure and channel interference. The ANRS will provide a simulation/stimulation tool and test bed environment that allow the researcher to predict the performance of various aeronautical network protocol standards and their associated waveforms under varying

A campus-community partnership can be an effective vehicle for launching environmental strategies to prevent college alcohol-related problems. In this study, the authors' primary aim was identifying key factors that facilitate or impede colleges' efforts to build campus-community partnerships. From fall 2004 to summer 2006, administrators at five 4-year colleges participated in a multisite case study. Level of partnership development was the primary outcome. Three interrelated factors facilitated higher-developed partnerships: college staff assigned to facilitate the partnerships who worked as community organizers, higher-level college administrators who served as aggressive champions, and community initiation of the partnership. The authors did not observe this trio of factors among the less-developed partnerships. A lack of administrative support made it more difficult for a champion to emerge, a college administrator who staunchly advocated for a campus-community partnership, and for those assigned to facilitate the partnership to carry out their work. Colleges should appoint higher-level administrators to serve as champions, while also ensuring that those assigned to facilitate a partnership can apply community organizing skills.

Mining with communities

Veiga, Marcello M.; Scoble, Malcolm; McAllister, Mary Louise

2001-01-01

To be considered as sustainable, a mining community needs to adhere to the principles of ecological sustainability, economic vitality and social equity. These principles apply over a long time span, covering both the life of the mine and post-mining closure. The legacy left by a mine to the community after its closure is emerging as a significant aspect of its planning. Progress towards sustainability is made when value is added to a community with respect to these principles by the mining operation during its life cycle. This article presents a series of cases to demonstrate the diverse potential challenges to achieving a sustainable mining community. These case studies of both new and old mining communities are drawn mainly from Canada and from locations abroad where Canadian companies are now building mines. The article concludes by considering various approaches that can foster sustainable mining communities and the role of community consultation and capacity building. (author)

The Role of Silence at the Retreats of a Buddhist Community

Directory of Open Access Journals (Sweden)

Orsolya Huszár

2016-12-01

Full Text Available The purpose of the study is to establish that the definition of silence as simply an absence of something or as the background of communication proves to be inadequate in a number of communicative instances. The interpretation of silence is culturally determined, and the underappreciation of its role is typical in low-context Western cultures; this is also evinced by the neglect of the topic in the literature. The present study will describe the communicative functions of silence through the findings of field work conducted at the retreats of a Buddhist community in Hungary, providing empirical input for the relevant theoretical constructs. The research findings show that silence is accorded a central role in essentially every component of the retreat (meditations, relaxation, ceremonies, teachings, small-group sharings, meals and rest; and while each event at the retreat focuses primarily on a different specific function of communication, the entire retreat does involve the linkage, affecting, revelational and – to a certain extent – activating functions (to follow the five-element typology of J. Vernon Jensen, as well as – to a lesser extent – the judgmental function. The research also shows that it requires time for individuals in a low-context culture to recognize the “point” of silence – something that the retreats provide the right opportunity for. In fact, the insights the individuals arrived at through these occasions could be put to use in their daily lives, helping their problem-solving and social relationships and in general improving their quality of life.

Community Ecology

CERN Document Server

1988-01-01

This book presents the proceedings of a workshop on community ecology organized at Davis, in April, 1986, sponsored by the Sloan Foundation. There have been several recent symposia on community ecology (Strong et. al., 1984, Diamond and Case, 1987) which have covered a wide range of topics. The goal of the workshop at Davis was more narrow: to explore the role of scale in developing a theoretical approach to understanding communities. There are a number of aspects of scale that enter into attempts to understand ecological communities. One of the most basic is organizational scale. Should community ecology proceed by building up from population biology? This question and its ramifications are stressed throughout the book and explored in the first chapter by Simon Levin. Notions of scale have long been important in understanding physical systems. Thus, in understanding the interactions of organisms with their physical environment, questions of scale become paramount. These more physical questions illustrate the...

Exploring the roles of cannot-link constraint in community detection via Multi-variance Mixed Gaussian Generative Model

2017-01-01

Due to the demand for performance improvement and the existence of prior information, semi-supervised community detection with pairwise constraints becomes a hot topic. Most existing methods have been successfully encoding the must-link constraints, but neglect the opposite ones, i.e., the cannot-link constraints, which can force the exclusion between nodes. In this paper, we are interested in understanding the role of cannot-link constraints and effectively encoding pairwise constraints. Towards these goals, we define an integral generative process jointly considering the network topology, must-link and cannot-link constraints. We propose to characterize this process as a Multi-variance Mixed Gaussian Generative (MMGG) Model to address diverse degrees of confidences that exist in network topology and pairwise constraints and formulate it as a weighted nonnegative matrix factorization problem. The experiments on artificial and real-world networks not only illustrate the superiority of our proposed MMGG, but also, most importantly, reveal the roles of pairwise constraints. That is, though the must-link is more important than cannot-link when either of them is available, both must-link and cannot-link are equally important when both of them are available. To the best of our knowledge, this is the first work on discovering and exploring the importance of cannot-link constraints in semi-supervised community detection. PMID:28678864

Fatherhood in Australian Aboriginal and Torres Strait Islander communities: An Examination of Barriers and Opportunities to Strengthen the Male Parenting Role.

Science.gov (United States)

Reilly, Lyndon; Rees, Susan

2018-03-01

Traditional Australian Aboriginal and Torres Strait Islander societies value men's role as parents; however, the importance of promoting fatherhood as a key social determinant of men's well-being has not been fully appreciated in Western medicine. To strengthen the Aboriginal and Torres Strait Islander male parenting role, it is vital to examine current barriers and opportunities. The first author (a male Aboriginal health project officer) conducted yarning sessions in three remote Australian communities, two being Aboriginal, the other having a high Aboriginal population. An expert sample of 25 Aboriginal and 6 non-Aboriginal stakeholders, including maternal and child health workers and men's group facilitators, considered barriers and opportunities to improve men's parenting knowledge and role, with an aim to inform services and practices intended to support men's parenting. A specific aim was to shape an existing men's group program known as Strong Fathers, Strong Families. A thematic analysis of data from the project identified barriers and opportunities to support men's role as parents. Challenges included the transition from traditional to contemporary parenting practices and low level of cultural and male gender sensitivity in maternal and child health services. Services need to better understand and focus on men's psychological empowerment and to address shame and lack of confidence around parenting. Poor literacy and numeracy are viewed as contributing to disempowerment. Communities need to champion Aboriginal and Torres Strait Islander male father role models. Biases and barriers should be addressed to improve service delivery and better enable men to become empowered and confident fathers.

Linking community resources in diabetes care: a role for technology?

Science.gov (United States)

Tung, Elizabeth L; Peek, Monica E

2015-07-01

Designing and implementing effective lifestyle modification strategies remains one of the great challenges in diabetes care. Historically, programs have focused on individual behavior change with little or no attempt to integrate change within the broader social framework or community context. However, these contextual factors have been shown to be associated with poor diabetes outcomes, particularly in low-income minority populations. Recent evidence suggests that one way to address these disparities is to match patient needs to existing community resources. Not only does this position patients to more quickly adapt behavior in a practical way, but this also refers patients back to their local communities where a support mechanism is in place to sustain healthy behavior. Technology offers a new and promising platform for connecting patients to meaningful resources (also referred to as "assets"). This paper summarizes several noteworthy innovations that use technology as a practical bridge between healthcare and community-based resources that promote diabetes self-care.

2008-04-01

Collaborative approaches to community health improvement such as healthy cities and communities have the potential to strengthen community capacity through leadership development. The healthy cities and communities process orients existing local leadership to new community problem-solving strategies and draws out leadership abilities among residents not previously engaged in civic life. In an evaluation of the California Healthy Cities and Communities (CHCC) Program, leadership development was one of several outcomes assessed at the civic-participation level of the social ecology. Data collection methods included focus groups and surveys, semistructured interviews with coordinators and community leaders, and review of program documents. Findings suggest that the CHCC program enhanced capacity by expanding new leadership opportunities through coalition participation, program implementation, and civic leadership roles related to spin-off organizations and broader collaborative structures. Communities in rural regions were particularly successful in achieving significant leadership outcomes.

2008-01-01

Identify useful concepts related to the emotional context facing family members of nursing home residents. These concepts can be used in future studies to design and test interventions that benefit family caregivers. Secondary data analyses of qualitative ethnographic data. Two nursing homes in a large Midwestern city; 8 months of data collection in each. 44 family members of nursing home residents whose health was considered, "declining." Role theory was used to design and help interpret the findings. Data included transcripts of conversations between family members and researchers and were analyzed using a coding scheme developed for the secondary analysis. Comments about emotions related to the social role of family member were grouped into three categories: relief related to admission, stress, and decision making support/stress. Subcategories of stress include the role strain associated with "competing concerns" and the psychological pressures of 1) witnessing the decline of a loved one in a nursing home, and 2) guilt about placement. Decision-making was discussed as a challenge which family members did not want to face alone; support from the resident, health care professionals, and other family members was appreciated. Family members may benefit from role reinforcement activities provided by nursing home staff and community members. All nursing home staff members (in particular social workers) and physicians are called upon to provide educationa and support regarding nursing home admissions, during the decline of the resident, and especially regarding medical decision-making. Community groups are asked to support the family member by offering assistance with concrete tasks (driving, visiting, etc.) and social support.

1988-01-01

The Minnesota Heart Health Program (MHHP) aims to reduce cardiovascular disease (CVD) morbidity and mortality by reducing risk factors among the mass of residents in three midwestern communities. A major aspect of the program is the involvement of community physicians because they have high credibility as citizen leaders, especially on health issues. In the MHHP, physicians contributed in a number of ways. The initial contacts with physicians resulted in their providing support and introductions to other community leaders, whose active support was also gained. Physicians sit as members of the central Community Advisory Borads of MHHP and serve on the executive committees of these boards. All MHHP issues related to medical practice are brought before Physicians' Advisory Groups in each community for resolution. Primary care physicians attend MHHP continuing education programs. In a survey of 109 physicians in one of the MHHP communities, 95 percent of respondents believed cigarette smoking to be an important risk factor for CVD, but only 15 percent judged themselves to be effective in dealing with patients who smoked. Forty-one percent of respondents said that elevated blood cholesterol is an important risk factor, but only 20 percent felt effective in treating the condition. Only 18 percent of the physicians in the sample believed that a poor eating pattern plays a substantial role in CVD, and 9 percent felt effective in counseling patients about eating habits. This pattern of results indicates the need not only for continuing education about risk factors for CVD, but also for training to improve patient counseling skills. PMID:3136495

2004-07-01

The community response of indigenous sandstone, chalk and limestone groundwater microorganisms to the addition of the commonly used herbicide isoproturon was examined. The addition of 100 microg l(-1) isoproturon generally caused an increase in species diversity determined by chemotaxonomic analysis (fatty methyl ester analysis) of isolates resulting from incubation of cultures at 18 degrees C for 4 days. Amongst the groundwater samples to which isoproturon was added, isoproturon degradation rates were correlated with increasing dominance of a few species. However, the changes in community profile associated with isoproturon degradation varied from site to site. Repeated sub-culturing with 100 microg l(-1) isoproturon and sterile groundwater was carried out to examine whether this level of pesticide could exert a selection pressure, and hence stimulate more rapid degradation. Significantly increased degradation was observed in a groundwater sample from the chalk, but not in sandstone, or limestone samples. The addition of filter-sterilised sandstone groundwater to bacteria on filter paper from slow degrading limestone sites significantly improved their degrading performance. The addition of filter-sterilised limestone groundwater to the sandstone bacteria reduced their degradation rate only slightly. The data suggested that the nature of the indigenous community does influence pesticide degradation in groundwater, but that the groundwater chemistry may also play a role.

Successful bioremediation of oil pollution is based on a comprehensive understanding of the in situ physicochemical conditions and indigenous microbial communities as well as the interaction between microorganisms and geochemical variables. Nineteen oil-contaminated soil samples and five uncontaminated controls were taken from six major oilfields across different geoclimatic regions in China to investigate the spatial distribution of the microbial ecosystem. Microbial community analysis revealed remarkable variation in microbial diversity between oil-contaminated soils taken from different oilfields. Canonical correspondence analysis (CCA) further demonstrated that a suite of in situ geochemical parameters, including soil moisture and sulfate concentrations, were among the factors that influenced the overall microbial community structure and composition. Phylogenetic analysis indicated that the vast majority of sequences were related to the genera Arthrobacter, Dietzia, Pseudomonas, Rhodococcus, and Marinobacter, many of which contain known oil-degrading or oil-emulsifying species. Remarkably, a number of archaeal genera including Halalkalicoccus, Natronomonas, Haloterrigena, and Natrinema were found in relatively high abundance in some of the oil-contaminated soil samples, indicating that these Euryarchaeota may play an important ecological role in some oil-contaminated soils. This study offers a direct and reliable reference of the diversity of the microbial community in various oil-contaminated soils and may influence strategies for in situ bioremediation of oil pollution.

A community perspective on the role of fathers during pregnancy: a qualitative study

Science.gov (United States)

2013-01-01

Background Defining male involvement during pregnancy is essential for the development of future research and appropriate interventions to optimize services aiming to improve birth outcomes. Study Aim: To define male involvement during pregnancy and obtain community-based recommendations for interventions to improve male involvement during pregnancy. Methods We conducted focus groups with mothers and fathers from the National Healthy Start Association program in order to obtain detailed descriptions of male involvement activities, benefits, barriers, and proposed solutions for increasing male involvement during pregnancy. The majority of participants were African American parents. Results The involved “male” was identified as either the biological father, or, the current male partner of the pregnant woman. Both men and women described the ideal, involved father or male partner as present, accessible, available, understanding, willing to learn about the pregnancy process and eager to provide emotional, physical and financial support to the woman carrying the child. Women emphasized a sense of “togetherness” during the pregnancy. Suggestions included creating male-targeted prenatal programs, enhancing current interventions targeting females, and increasing healthcare providers’ awareness of the importance of men’s involvement during pregnancy. Conclusions Individual, family, community, societal and policy factors play a role in barring or diminishing the involvement of fathers during pregnancy. Future research and interventions should target these factors and their interaction in order to increase fathers’ involvement and thereby improve pregnancy outcomes. PMID:23497131

I use the example of our case study to suggest that adult educatorscan generate viable communities by creating learning spaces that nurture criticalconsciousness, a sense of agency, participation and social solidarity amonginternationally and culturally diverse young adult learners. Furthermore, I argue thatparticipation in international learning communities formed through this educationalprocess can potentially help young adults become locally and globally engaged citizens.International learning communities for global citizenship thus present a proposition forconceptualizing the vital role of adult community education in supporting democraticglobal and local citizenship in a world defined in terms of cross-cultural and longdistanceencounters in the formation of culture.

This study further explored the impact of sectarian violence and children’s emotional insecurity about community on child maladjustment using a four-wave longitudinal design. The study included 999 mother-child dyads in Belfast, Northern Ireland (482 boys, 517 girls). Across the four-waves, child mean age was 12.19 (SD = 1.82), 13.24 (SD = 1.83), 13.61 (SD = 1.99), and 14.66 years (SD = 1.96), respectively. Building on previous studies of the role of emotional insecurity in child adjustment, the current study examines within-person change in emotional insecurity using latent growth curve analyses. The results showed that children’s trajectories of emotional insecurity about community were related to risk for developing conduct and emotion problems. These findings controlled for earlier adjustment problems, age and gender, and took into account the time-varying nature of experience with sectarian violence. Discussion considers the implications for children’s emotional insecurity about community for relations between political violence and children’s adjustment, including the significance of trajectories of emotional insecurity over time.
