Sand cores and surface sand samples have been collected from the sea-facing intertidal regions of West Cumbria, between Silloth and Walney Island. Sand cores were also taken from the Duddon estuary and Morecambe Bay. The samples were collected between June 1983 and March 1984 and have been analysed for 238 Pu, 239+240 Pu and 241 Am. The integrated deposits of 239+240 Pu and 241 Am in intertidal sand between Silloth and Walney Island were about 4.2 and 7 TBq respectively. Combined, this represents about 1% of the total alpha-emitting actinide activity discharged from Sellafield to sea up to 1982; the corresponding value for the Duddon Estuary is about 0.3%. The actinide levels observed are compared to those of natural alpha emitters in intertidal sand. Only on beaches close to Sellafield did levels of discharged alpha emitters exceed those of natural alpha-emitting nuclides. In the vicinity of Sellafield, the annual dose to man from the inhalation of resuspended intertidal material is certainly less than 50 μSv (committed effective dose equivalent) and may be substantially lower.

To assess the sustainability of the business model underlying the North Dakota Telepharmacy Project (NDTP). Of the 38 community pharmacy organizations (14 central, 24 remote), 27 organizations (11 central and 16 remote sites) in North Dakota provided a useable set of responses (71.1% response rate). A twelfth organization (a community pharmacy) ceased operations over the study's time frame and was not included in the data analysis. Emphasis is placed on NDTP community telepharmacies, because the community telepharmacy business model is more established than hospital telepharmacies. Yet little is known about the long-run financial viability of telepharmacies. Originally funded by a series of federal grants, the goal of the NDTP was to create the infrastructure necessary to support the development of telepharmacy sites. A 48-item questionnaire assessed the self-reported operational, financial, and community impacts of a community telepharmacy. The questionnaire was administered from December 2015 to February 2016 to all NDTP community telepharmacy owners-managers. Thus, 1 participant (owner-manager) addressed both central and remote-site locations served by a pharmacy. Most respondents reported that their telepharmacy sites (especially remote sites) generate small positive financial returns for the organization. Respondents also reported that the closure of their remote sites would significantly harm the communities they serve. NDTP aims of restoration and retention have been achieved via the investment and shared decision making with pharmacy owners in North Dakota. The telepharmacy model is sustainable, even if it does not generate significant economic profit. Copyright © 2017 American Pharmacists Association®. Published by Elsevier Inc. All rights reserved.

A mathematical model is described which represents the sea-to-land transfer of actinides discharged into the Irish Sea from the Sellafield reprocessing plant. The model successfully reproduces the marine distribution of plutonium and americium in the Irish Sea between Cumbria and the Isle of Man and evaluates the magnitude of the transfer process to land. The radiological consequences of this transfer are calculated for the years 1954 to 2000 taking into account actual and future predicted discharges. The contribution from nuclear weapon tests and from Sellafield's atmospheric discharges are also evaluated and compared. The calculated annual dose from sea-to-land transfer to the average person living in Seascale reached a maximum of 24 microSieverts in 1973 and declined subsequently to 4 microSieverts by 1985 compared with the recommended ICRP principal limit for the general public of 1000 microSieverts. Corresponding figures for a hypothetical critical group are 35 microSieverts in 1973 and 20 microSieverts in 1985. The dose has decreased less steeply since 1973 than the corresponding decrease in discharges from Sellafield over the same period reflecting recycling of actinides accumulated in sea-bed deposits. Dose calculations for use of the beach at Seascale are also included. (author)

The cases of childhood leukaemia found among children of the Sellafield (West Cumbria), Ontario and Scottish radiation workers and in the offspring of the Japanese bomb survivors are analysed using linear and exponential forms of a relative risk model with total preconception external radiation dose estimates. In particular, the risks among children of the Sellafield workforce born in Seascale and among those born elsewhere in West Cumbria are compared with the risks derived from the other datasets. There is a highly significant inconsistency between the raised paternal preconception exposure excess relative risk coefficients for leukaemia in those children of the Sellafield workforce born in Seascale and the coefficients for children born elsewhere in West Cumbria, those for the offspring of the Ontario or Scottish workforces as well as those for the offspring of the Japanese bomb survivors. These incompatabilities are independent of the models used. In contrast to this, the leukaemia excess relative risk coefficients for paternal preconception exposure of those children of the Sellafield workforce born elsewhere in West Cumbria are not significantly elevated and do not differ significantly from those observed in the Japanese, Ontario and Scottish datasets.

Microbial communities of the Chinese marginal seas have rarely been reported. Here, bacterial and archaeal community structures and abundance in the surface sediment of four sea areas including the Bohai Sea (BS), North Yellow Sea (NYS), South Yellow Sea (SYS), and the north East China Sea (NECS) were surveyed by 16S ribosomal RNA (rRNA) gene pyrosequencing and quantitative PCR. The results showed that microbial communities of the four geographic areas were distinct from each other at the operational taxonomic unit (OTU) level, whereas the microbial communities of the BS, NYS, and SYS were more similar to each other than to the NECS at higher taxonomic levels. Across all samples, Bacteria were numerically dominant relative to Archaea, and among them, Gammaproteobacteria and Euryarchaeota were predominant in the BS, NYS, and SYS, while Deltaproteobacteria and Thaumarchaeota were prevalent in the NECS. The most abundant bacterial genera were putative sulfur oxidizer and sulfate reducer, suggesting that sulfur cycle processes might prevail in these areas, and the high abundance of dsrB (10(7)-10(8) copies g(-1)) in all sites verified the dominance of sulfate reducer in the north Chinese marginal seas. The differences in sediment sources among the sampling areas were potential explanations for the observed microbial community variations. Furthermore, temperature and dissolved oxygen of bottom water were significant environmental factors in determining both bacterial and archaeal communities, whereas chlorophyll a in sediment was significant only in structuring archaeal community. This study presented an outline of benthic microbial communities and provided insights into understanding the biogeochemical cycles in sediments of the north Chinese marginal seas.

Assessing the geographic origin of the invasive grey squirrel using DNA sequencing: Implications for management strategies

Directory of Open Access Journals (Sweden)

Claire D. Stevenson-Holt

2015-01-01

Full Text Available The invasive grey squirrel Sciurus carolinensis has become a major pest species causing negative effects to forestry and biodiversity. This study aims to assess the origin of grey squirrel within Cumbria using phylogeographic analysis to aid in management and control. The work reported analysed mitochondrial DNA sequences in the D-Loop gene of 73 grey squirrel individuals from multiple locations in the UK. The results indicate that individuals in north Cumbria are derived from individuals from Scotland and North East England. Other individuals in north Cumbria share a unique haplotype with south Cumbria and Lancashire suggesting a southerly origin and movement around or over the Cumbrian Mountain range which is thought of as a barrier to movements. The assessment of invasive species geographical origin and the identification of potential wildlife transit corridors through natural barriers are becoming more important as species shift range in response to environmental and ecological changes. With the grey squirrel population expansion also occurring in Italy, the European red squirrel may become threatened across its entire range. It is crucial to understand the population origins of the invasive grey squirrel and landscape usage to successfully manage the incursion routes and control the population.

Implications of sedimentological and hydrological processes on the distribution of radionuclides: the example of a salt marsh near Ravenglass, Cumbria

International Nuclear Information System (INIS)

Carr, A.P.; Blackley, M.W.L.

1986-01-01

This paper summarizes sedimentological and hydrological studies at a salt marsh site on the north bank of the River Esk near Ravenglass which have a bearing on the fate of the low-level radioactive effluent from the reprocessing facility at Sellafield, Cumbria. A range of techniques has been used including electromagnetic distance measurement (EDM) and pore water pressure studies. The results show that: (a) Over a two-year period there were no significant net changes in salt marsh creek level, although shorter-term (probably seasonal) fluctuations, of the order of 2 cm, occurred. These were attributed to expansion of clay particles during the winter months. Nearby, however, there were vertical changes of the order of 1 m due to erosion. (b) Pore water pressures indicated a dynamic situation with very rapid responses both to tidal fluctuations and to rainfall. During neap tides there was clear evidence for water seeping upwards from the underlying clay/sand interface. Shortlived radionuclides ( 95 Zr/ 95 Nb and 106 Ru) were detected in this zone. (c) soil polygons, once initiated by desiccation, thereafter provide preferential routes for water (and radionuclides) to the sub-surface sediment. These, and other results, are discussed in the context of previous studies. It is concluded that the complexity of the estuarine environment results in most data being site specific. (author)

Leaching studies of low-level waste as input to radiological assessment at the Drigg disposal site, Cumbria

International Nuclear Information System (INIS)

Poulton, J.; Rushbrook, P.E.

1989-01-01

Over the period of operation of the low-level waste disposal site at Drigg in Cumbria, several radiological assessments have been carried out. This paper discusses data requirements for such an assessment and in particular describes a project to measure the leaching behaviour of wastes. This project, jointly set up by the staff of BNFL and Environmental Safety Centre at Harwell, began in 1985. The objectives were to determine the processes operating within the waste disposal trenches at Drigg and conditions affecting them. The paper describes the installation and operation of the first of a series of lysimeters designed to simulate conditions in current trenches. (author)

School and community relations in North America: Creative tensions

Science.gov (United States)

Loughran, E.; Reed, H. B.

1980-09-01

School and community relations in North America reflect creative tensions between the conserving forces of schooling and the changing forces of community. During crisis periods community development needs may modify the school's focus on individual learner growth, but generally schools use the community to extend and enrich the traditional modes. School and community interactions are chiefly characterized by such settings as community schools, community education, adult education, home and school (PTA) associations, work-study programs, curriculum-community resource programs. Recent social forces are creating heightened tensions: cultural pluralism, reduced resources, Third World influences, international conflicts, personal alienation, population concerns, energy problems, community power issues. These forces are gradually shifting school and community concepts towards ones of education and community. Education goes well beyond schooling, including all agencies having an organized influence on community development: libraries, voluntary groups, unions, business, human service agencies, government units, as well as schools. This shift requires research to develop nonformal concepts and practices, along with formal pedagogy, to increase the positive impacts of educational networks on community, as well as individual, development. These new directions have not yet significantly modified the traditional meaning of school and community relations.

Radionuclide behaviour in a coniferous woodland ecosystem in Cumbria, UK

International Nuclear Information System (INIS)

Jones, S.R.; Copplestone, D.; Johnson, M.S.

1996-01-01

The behaviour of 134Cs, 137Cs, 238Pu, 239+240Pu and 241Am, in food chains in a semi-natural woodland has been investigated and doses to the ecosystem due to the presence of these radionuclides of anthropogenic origin have been assessed. The woodland is located within 1 km of the coastal British Nuclear Fuels plc (BNFL) reprocessing plant at Sellafield, Cumbria (O.S. Grid Reference: NY 037045) and has received an input of radionuclides primarily through atmospheric discharges from the Sellafield site throughout its operational history of more than 40 years. Deposition has been enhanced by interception by the canopy, such that deposits in the woodland are significantly higher than adjacent pasture land. Within the wood, deposition is greatest along the front (or leading) edge in relation to aerosols transported to the woodland from Sellafield, due to the 'edge effect'. Despite the high radionuclide deposits, relatively low uptake and mobility within the ecosystem was observed. Estimated doses to the ecosystem at around 2 mGy a -1 , were dominated by external irradiation and were well below the levels thought to be necessary to harm terrestrial ecosystems. A provisional conclusion at this stage is that the measures taken to control emissions from Sellafield in line with radiological protection standards for humans have also been adequate to protect this potentially vulnerable ecosystem

2007-01-01

Following the Chernobyl accident in 1986, restrictions were placed on the movement and slaughter of sheep within upland areas of the UK because radiocaesium activity concentrations in their meat exceeded 1000 Bq kg -1 fresh weight. Some farms remain under restriction in 2007. From 1991 to 1993 detailed studies were conducted on three sheep farms within the restricted area of west Cumbria to systematically assess the various parameters which may contribute to the observed variability in radiocaesium activity concentrations within sheep flocks. This paper reports the spatial variation in soil and vegetation activity concentrations across the grazed areas at these farms and determines the influence of grazing behaviour on variability in 137 Cs activity concentrations between individual sheep within the flocks. Together with previously reported results, these new data are used to draw conclusions on the factors determining variability within the three flocks. However, the factors are too site specific to be able to generalise the findings to other farms within the restricted areas of the UK

Doses to Terrestrial Biota in the Vicinity of BNFL Sellafield, Cumbria, UK (invited paper)

Source terms and corresponding radionuclide activity concentrations in biota for {sup 134}Cs, {sup 137}Cs, {sup 238}Pu, {sup 239+240}Pu and {sup 241}Am have been assessed for three semi-natural ecosystems in the vicinity of BNFL Sellafield, Cumbria, UK. Estimates of absorbed doses (mGy.d{sup -1}) have been calculated. Doses to key indicator species, Oniscus asellus (detritivorous invertebrate), Carabus violaceous (predatory invertebrate) and Apodemus sylvaticus (granivorous wood mouse) are discussed with reference to the 1 mGy.d{sup -1} level, below which it is postulated that no observable effects on populations in a terrestrial ecosystem occur. Implications for the 'critical group' and 'reference model' approaches for a framework of radiological environmental protection are discussed. The need to assess the most highly exposed species is advanced. New research focused on the application of biomarker techniques as a mechanism for determining the interactions and effects of environmental contaminants on ecosystem structure and functioning is presented.

Community involvement: stake holder learning in the UK and in Canada

International Nuclear Information System (INIS)

Hetherington, J.

2003-01-01

Copeland District in west Cumbria in the North-West Region of England, is 'home' to the major UK (Sellafield) reprocessing plants (including THORP). The Sellafield site includes major stores for Intermediate (ILW) and High Level Waste (HLW), while the nearby Drigg national site provides a facility for the managed surface disposal of Low Level Waste (LLW). Together these facilities dominate the local economy, proving some 10 000 jobs and making a key contribution to the local economy. In the 1990's the area was also highlighted as the potential location for a national ILW deep waste repository. This paper offers a reflection from a UK community perspective on the deliberations of the FSC Canadian Workshop. It provides, as background, an initial introductory account of: the development of radioactive waste and liabilities management policy in the UK, the significance of the failure of the Nirex RCF proposals, the success of new dialogue approaches, and the new wide ranging UK radioactive waste management consultation process. It then compares the economic and social issues arising at Sellafield with issues identified in the Canadian programmes and experiences as presented at the Workshop. (author)

Mineralogy and petrography of samples of Permo-Triassic sedimentary strata from Cumbria

Kemp, S.J.; Milodowski, A.E.; Bloodworth, A.J.

1989-03-01

The mineralogy and petrography of Permo-Triassic sediments from Cumbria are described. The samples are duplicates of those selected for sorption experiments by Harwell Laboratory and are considered representative of Permo-Triassic strata underlying the BNFL Sellafield site. The regional geological context of the samples is briefly discussed. X-ray diffraction analysis indicates that the St Bees Sandstone and Eden Shales samples are predominantly composed of quartz with minor feldspar, gypsum and hematite. The clay assemblage is formed of dioctahedral mica and trioctahedral chloride with minor kaolinite. Diagnostic testing also reveals the presence of corrensite, a regularly interstratified chlorite-smectite, in one of the samples. Possible diagenetic processes responsible for corrensite formation, including the alteration of originally deposited smectite by magnesium-rich pore waters, are discussed. Modelling of the diffraction profile indicates that the chlorite and corrensite are iron-rich species. Back scattered electron microscopy shows the samples to be typical red bed sediments exhibiting framework grain dissolution, the breakdown and replacement of unstable ferromagnesian minerals being accompanied by the precipitation of hematite and anatase. Particle-size analysis shows similar distributions for the St Bees Sandstone samples but a greater proportion of clay material in the Eden Shales. (author)

Late Cretaceous restructuring of terrestrial communities facilitated the end-Cretaceous mass extinction in North America.

Mitchell, Jonathan S; Roopnarine, Peter D; Angielczyk, Kenneth D

2012-11-13

The sudden environmental catastrophe in the wake of the end-Cretaceous asteroid impact had drastic effects that rippled through animal communities. To explore how these effects may have been exacerbated by prior ecological changes, we used a food-web model to simulate the effects of primary productivity disruptions, such as those predicted to result from an asteroid impact, on ten Campanian and seven Maastrichtian terrestrial localities in North America. Our analysis documents that a shift in trophic structure between Campanian and Maastrichtian communities in North America led Maastrichtian communities to experience more secondary extinction at lower levels of primary production shutdown and possess a lower collapse threshold than Campanian communities. Of particular note is the fact that changes in dinosaur richness had a negative impact on the robustness of Maastrichtian ecosystems against environmental perturbations. Therefore, earlier ecological restructuring may have exacerbated the impact and severity of the end-Cretaceous extinction, at least in North America.

2003-06-01

Full Text Available Classification of tall-forb vegetation of the Altai using the Braun-Blanquet approach was carried out on the basis of a wide ranging set o[ data from different altitudinal belts. Three main phytosociological types of the tall-forb communities were distinguished within the class MulgedioAconitetea, order Tmllio - Crepidetalia due to performed syntaxonomic analysis. The thermophilous tall-forb communities occurring in the subnemoral belt at altitudes of 259-700 m were included in the alliance Cacalio hastatae - Aconition septentrionalis all. nova. The montain tall-forb meadows of the dark-coniferous taiga belt (altitudes of 800-1700 m were included in the alliance Triseto sibiricae-Aconirlon septentrionalis all. prov. The moderately cryophilous subalpine tall-forb communities widespread at the upper boundary of the forest belt at altitudes of 1000-1900 m were included in the alliance Rhaponticion carthamoidis. Altaian tall-forb vegetation shows a distinct phytosociological and plant geographical unity with European subalpine communities but the closeness of the floristic relations varies in certain altitudinal groups. Most thermophilous tall-forb Siberian meadows of the alliance Cacalio-Aconition which occur at lower altitudes demonstrate strong plant geographical relations with North and Central European meadows of the Adenostyletalia. Gradual decrease of the European floristic relations in the Altaian tall-forb meadows at higher altitudes is shown.

Reimagining Energy in the North: Developing Solutions for Improving Renewable Energy Security in Northern Communities

Creed, I. F.; Poelzer, G.; Noble, B.; Beatty, B.; Belcher, K.; Chung, T.; Loring, P. A.

2017-12-01

The global energy sector is at a crossroads. Efforts to reduce greenhouse gas emissions, volatile fossil fuel prices, the emergence of sustainability markets, and advances in renewable energy technologies are setting the foundation for what could be one of the most significant societal transitions since the industrial revolution. There is a growing movement to "re-energize" Canada, through embracing pathways to facilitate a societal transition a low-carbon future. For example, circumpolar jurisdictions are poised for a transition to renewable energy. There are more than 250 remote, off-grid communities across Canada's North, of which approximately 170 are Indigenous, that rely largely on diesel-fueled generators. Diesel-fueled generation is generally reliable when properly maintained; however, supply is limited, infrastructure is at capacity or in need of major upgrading, and the volatile price of fuel can mean significant social, community and economic opportunity loss. Renewable energy projects offer one possible opportunity to address these challenges. But, given the challenges of human capacity, limited fiscal resources, and regulatory barriers, how can Northern communities participate in the global energy transition and not be left behind? To answer this question, the University of Saskatchewan, together with partners from the circumpolar North, are leading an initiative to develop a cross-sectoral and multi-national consortium of communities, utilities, industries, governments, and academics engaged in renewable energy in the North. This consortium will reimagine energy security in the North by co-creating and brokering the knowledge and understanding to design renewable energy systems that enhance social and economic value. Northern communities and utilities will learn directly from other northern communities and utilities across Canada and internationally about what can be achieved in renewable energy development and the solutions to current and future

Mondon, K.J.; Walters, B.

1993-01-01

The Ministry of Agriculture, Fisheries and Food has conducted a duplicate diet study around the BNF reprocessing plant of Sellafield in Cumbria. Samples were collected from adults and children. The results of analyses for a number of artificial radionuclides are reported; dose calculations using actual food intakes have also been made. Samples were obtained in both winter (phase 1) and summer (phase 11), between which times the Chernobyl accident occurred, making site-specific dose assessment from caesium isotopes difficult in summer samples. Control diets were collected from a coastal area in Lancashire. Average annual doses based on pre-Chernobyl sampling ranged from 2 μSv in control children to 14 μSv in study adults. This range increased to 9-50 μSv in the second phase of the study. Maximum individual doses were 86 μSv in phase 1 and 102 μ in phase 11, these being well within the government's target dose for members of the public. (author)

Child leukaemia around Sellafield: local community attitudes and the Black Report

Energy Technology Data Exchange (ETDEWEB)

Macgill, S M; Berhout, F G

1985-01-01

The purpose of this paper is to evaluate the relevance of the Black Report to the communities whose situation it was primarily addressing - the communities of the towns and villages around Sellafield in West Cumbria. The authors are concerned (1) with examining in what ways and to what extent the Black Report was received by these communities, (2) with examining the extent to which these communities were reassured by the report's message (and, prior to that, in need of reassurance); and, (3) with revealing and examining the terms in which local people themselves speak about the report and related issues. Through a comprehensive linguistic analysis of these aspects the authors are concerned, inter alia, to recast the research priorities and methodology of work on risk 'perception'. The analysis and evaluation draws on an original local attitude survey and is set against a number of contextual points.

The authors are concerned (1) with examining in what ways and to what extent the Black Report was received by these communities, (2) with examining the extent to which these communities were reassured by the report's message (and, prior to that, in need of reassurance); and, (3) with revealing and examining the terms in which local people themselves speak about the report and related issues. Through a comprehensive linguistic analysis of these aspects the authors are concerned, inter alia, to recast the research priorities and methodology of work on risk 'perception'. The analysis and evaluation below draws on an original local attitude survey and is set against a number of contextual points. (author)

Petrographic and sedimentological characteristics of drift sediments from the radiotracer experiment array at Drigg, Cumbria

Milodowski, A.E.

1990-11-01

A detailed petrographic, mineralogical and sedimentological study has been made of five drift sediment cores taken from shallow boreholes at Drigg, Cumbria, forming part of the British Geological Survey's migration test borehole array. The cores correspond to the aquifer in which tests are undertaken. The study shows that several discrete units can be recognised within the aquifer but that these may vary laterally by a considerable amount over short distances. The sands and silts comprising the aquifer zone are generally finely laminated and show an upwards coarsening of grain size. They are interpreted as proximal glacial sediments, possibly having been deposited in a lake or ponded basin. Petrographic analysis shows that most of the porosity is lined by detrital ferruginous illitic clay which coats the sand grains. Some evidence of feldspar dissolution is identified. Pyrite is also present as an important detrital component. In the upper part of the aquifer the pyrite has been largely oxidised to form secondary ferric oxide compounds. However, pyrite increases in abundance with depth and its preservation may reflect a variation in redox across the aquifer. (author)

Our state's motto is "Esse quam videri - To be rather than to seem." North Carolina struggles with insufficient systems to adequately address the opioid crisis we are experiencing. However, progress is happening. Leaders are making a difference across organizations, partnerships, and communities large and small. Where there is a will, North Carolina people are finding creative solutions to address the opioid crisis and its underlying health issues. We cannot wait. We cannot seem. We cannot be afraid. ©2018 by the North Carolina Institute of Medicine and The Duke Endowment. All rights reserved.

Advances in habitat and climate modelling allow us to reduce uncertainties of climate change impacts on species distribution. We evaluated the impacts of future climate change on community structure, diversity, distribution and phenology of 14 copepod species in the North Atlantic. We developed and validated habitat models for key zooplankton species using continuous plankton recorder (CPR) survey data collected at mid latitudes of the North Atlantic. Generalized additive models (GAMs) were applied to relate the occurrence of species to environmental variables. Models were projected to future (2080–2099) environmental conditions using coupled hydroclimatix–biogeochemical models under the Intergovernmental Panel on Climate Change (IPCC) A1B climate scenario, and compared to present (2001–2020) conditions. Our projections indicated that the copepod community is expected to respond substantially to climate change: a mean poleward latitudinal shift of 8.7 km per decade for the overall community with an important species range variation (–15 to 18 km per decade); the species seasonal peak is expected to occur 12–13 d earlier for Calanus finmarchicus and C. hyperboreus; and important changes in community structure are also expected (high species turnover of 43–79% south of the Oceanic Polar Front). The impacts of the change expected by the end of the century under IPCC global warming scenarios on copepods highlight poleward shifts, earlier seasonal peak and changes in biodiversity spatial patterns that might lead to alterations of the future North Atlantic pelagic ecosystem. Our model and projections are supported by a temporal validation undertaken using the North Atlantic climate regime shift that occurred in the 1980s: the habitat model built in the cold period (1970–1986) has been validated in the warm period (1987–2004).

Aquaculture expansion has been reported as the primary driver of mangrove loss and a significant cause of mangrove deforestation in North Sumatra, Indonesia. Development of silvofishery based on creating balance condition between conserving mangrove forest and offering better livelihood for local communities surrounding mangrove. The present study evaluates of mangrove management through community-based silvofishery in three villages, namely Paluh Manan, Paluh Kurau, and Lama, Hamparan Perak of Deli Serdang Regency, North Sumatra, Indonesia. Three communities used the same ecological type-silvofishery, characterized by planted mangrove surrounded aquaculture. Results showed that in the Paluh Manan village, planted mangrove and aquaculture in the ratio of 75:25 with planting distance of mangrove 50x50 cm, containing 2,500 trees/ha, resulted in US 36.2/month/ha of fish and shrimp farming. In the Paluh Kurau village, a mixture mangrove and aquaculture in an 84:16 ratio, planting distance of 1x1 m, consists of 1,600 trees/ha, US 23.8 of generating revenue from crab farming. Furthermore, in the third village, Lama village, consists of mangrove and aquaculture in the proportions 90:10, with planting spacing 2x2 m, composing 1,000 trees/ha, led to US 45.8/month/ha from fish, shrimp and crab farming. The present study suggested the mangrove management through community-based mangrove-friendly aquaculture.

Research indicates that fear of immigration enforcement among Latinos in North Carolina results in limited access to and utilization of health services and negative health consequences. This project developed recommendations to mitigate the public health impact of immigration enforcement policies in North Carolina. Our community-based participatory research partnership conducted 6 Spanish-language report-backs (an approach to sharing, validating, and interpreting data) and 3 bilingual forums with community members and public health leaders throughout North Carolina. The goals of these events were to discuss the impact of immigration enforcement on Latino health and develop recommendations to increase health services access and utilization. Findings from the report-backs and forums were analyzed using grounded theory to identify and refine common recommendations. A total of 344 people participated in the report-backs and forums. Eight recommendations emerged: increase knowledge among Latinos about local health services; build capacity to promote policy changes; implement system-level changes among organizations providing health services; train lay health advisors to help community members navigate systems; share Latinos' experiences with policy makers; reduce transportation barriers; increase schools' support of Latino families; and increase collaboration among community members, organizations, health care providers, and academic researchers. Representatives from 16 of 100 North Carolina counties participated. These 16 counties represent geographically diverse regions, and many of these counties have large Latino populations. Immigration enforcement is a public health issue. Participants proposed developing new partnerships, identifying strategies, and implementing action steps for carrying out recommendations to reduce negative health outcomes among Latinos in North Carolina. ©2016 by the North Carolina Institute of Medicine and The Duke Endowment.

Collaborative community hazard exposure mapping: Distant Early Warning radar sites in Alaska's North Slope

Science.gov (United States)

Brady, M.

2015-12-01

A method to produce hazard exposure maps that are developed in collaboration with local coastal communities is the focus of this research. Typically efforts to map community exposure to climate threats over large areas have limited consideration of local perspectives about associated risks, constraining their utility for local management. This problem is especially acute in remote locations such as the Arctic where there are unique vulnerabilities to coastal threats that can be fully understood only through inclusion of community stakeholders. Through collaboration with community members, this study identifies important coastal assets and places and surveys local perspectives of exposure to climate threats along Alaska's vast North Slope coastline spanning multiple municipalities. To model physical exposure, the study adapts the U.S. Geological Survey's (USGS) coastal vulnerability index (CVI) to the Arctic context by incorporating the effects of open water distance determined by sea ice extent, and assigning CVI values to coastal assets and places according to direction and proximity. The study found that in addition to concerns about exposed municipal and industrial assets, North Slope communities viewed exposure of traditional activity sites as presenting a particular risk for communities. Highly exposed legacy Cold War Distant Early Warning Line sites are of particular concern with impacts ranging from financial risk to contamination of sensitive coastal marine environments. This research demonstrates a method to collaboratively map community exposure to coastal climate threats to better understand local risks and produce locally usable exposure maps.

Multiple myeloma in South Cumbria 1974-80: problems of health analysis in small communities

Jessop, E.G.; Horsley, S.D.

1985-01-01

The occurrence of seven cases of multiple myeloma over seven years in a small community 15 miles from a plant reprocessing nuclear fuel caused much local concern. A case control study of 34 confirmed cases in the health district during 1974 to 1980 revealed no excess of known risk factors among the 23 cases for whom informants could be traced. The possible effects of exposure to marine discharges of radioactive material cannot be completely ruled out, but dose estimates make this highly unlikely. Such studies are a necessary response by community physicians to the population they serve but have major practical and theoretical limitations. (author)

Anthropogenic climate change drives shift and shuffle in North Atlantic phytoplankton communities.

Barton, Andrew D; Irwin, Andrew J; Finkel, Zoe V; Stock, Charles A

2016-03-15

Anthropogenic climate change has shifted the biogeography and phenology of many terrestrial and marine species. Marine phytoplankton communities appear sensitive to climate change, yet understanding of how individual species may respond to anthropogenic climate change remains limited. Here, using historical environmental and phytoplankton observations, we characterize the realized ecological niches for 87 North Atlantic diatom and dinoflagellate taxa and project changes in species biogeography between mean historical (1951-2000) and future (2051-2100) ocean conditions. We find that the central positions of the core range of 74% of taxa shift poleward at a median rate of 12.9 km per decade (km⋅dec(-1)), and 90% of taxa shift eastward at a median rate of 42.7 km⋅dec(-1) The poleward shift is faster than previously reported for marine taxa, and the predominance of longitudinal shifts is driven by dynamic changes in multiple environmental drivers, rather than a strictly poleward, temperature-driven redistribution of ocean habitats. A century of climate change significantly shuffles community composition by a basin-wide median value of 16%, compared with seasonal variations of 46%. The North Atlantic phytoplankton community appears poised for marked shift and shuffle, which may have broad effects on food webs and biogeochemical cycles.

Samples of surface sand and sand cores were collected from intertidal regions of west Cumbria between Silloth and Walney Island (including the Duddon Estuary) between 1982 and 1984 and analysed for 238 Pu, 239+240 Pu and 241 Am. Generally, more than 95% of the α-emitting transuranic nuclides were associated with the sand and less than 5% with entrained silt. The greatest concentrations of both plutonium and americium were found at Braystones. Concentrations declined with distance from the Sellafield Works. The largest actinide deposits occurred at Drigg (320 and 720 kBq m -2 of 239+240 Pu and 241 Am respectively). The integrated deposits in intertidal sand between Silloth and Walney Island were about 4.2 and 7.0 TBq respectively, which represent about 1% of the total α-emitting activity discharged to sea from Sellafield Works up to 1982. The corresponding value for the Duddon Estuary is about 0.3%. Only on beaches close to Sellafield did levels of man-made α-emitters exceed those of natural α-emitting nuclides. The radiological consequences of the intertidal inventory of plutonium and americium are shown to be very small and much less than from the seafood pathway. (author)

Dendrodrilus rubidus were sampled from a mine spoil soil at Coniston Copper Mine, an abandoned Cu mine in Cumbria, UK and a Cu-free control site. Earthworms were maintained for 14 d in both Kettering loam and a Moorland soil amended with Cu nitrate. Mortality, condition index, weight change and tissue concentration were determined. In both soils D. rubidus native to the mine site were able to tolerate significantly higher soil Cu concentrations (MWRT, p ≤ 0.001), and exhibited significantly less change in weight (t-test, p ≤ 0.001) and a lower loss in condition (t-test, p ≤ 0.001) than control earthworms. For a given soil Cu concentration tissue Cu concentrations were greater in the mine site earthworms. Low cocoon production and viability from the mine site population prevented the determination of toxicity parameters on the F1 generation and may be an indicator of the cost of tolerance to the population. - Dendrodrilus rubidus at an abandoned Cu mine tolerates high Cu concentrations by accumulating more Cu before toxic effects occur compared to non-native populations

Objective Rural north-central Liberia has one of the world's highest maternal mortality ratios. We studied health facility birthing service utilisation and the motives of women seeking or not seeking facility-based care in north-central Liberia. Design Cross-sectional community-based structured interviews and health facility medical record review. Setting A regional hospital and the surrounding communities in rural north-central Liberia. Participants A convenience sample of 307 women between 15 and 49 years participated in structured interviews. 1031 deliveries performed in the regional hospital were included in the record review. Primary outcomes Delivery within a health facility and caesarean delivery rates were used as indicators of direct utilisation of care and as markers of availability of maternal health services. Results Of 280 interview respondents with a prior childbirth, only 47 (16.8%) delivered their last child in a health facility. Women who did not use formal services cited cost, sudden labour and family tradition or religion as their principal reasons for home delivery. At the regional hospital, the caesarean delivery rate was 35.5%. Conclusions There is an enormous unmet need for maternal health services in north-central Liberia. Greater outreach and referral services as well as community-based education among women, family members and traditional midwives are vital to improve the timely utilisation of care. PMID:23117566

The Nirex Safety Assessment Research Programme includes an investigation into the effects of cellulosic degradation products on the sorption of radioelements onto geological materials. Previous batch sorption studies have shown that the presence of high concentrations of both authentic cellulosic degradation products (produced by alkaline degradation of wood/tissue) and the well-characterised simulant, gluconate, can cause marked reductions in actinide sorption. This work has now been extended to cover a range of concentrations of both authentic cellulosic degradation products and their simulants, gluconate and iso-saccharinate. Geological samples were from the proposed Nirex underground radioactive waste disposal site at Sellafied, Cumbria. The nuclides studied were thorium and plutonium. In the presence of gluconate or iso-saccharinate, at concentrations above 10 -4 M, the present work has confirmed the trends shown by earlier experiments, with a significant reduction in actinide sorption (R D values reduced by less than a factor of two), and in some cases the results suggested a slight increase (R D values increased by up to a factor of four).

To measure satisfaction and motivation of community-based preceptors, and to examine differences between degree groups of physicians, pharmacists, advanced-practice nurses (nurse practitioners and certified nurse midwives), and physician assistants. In spring 2005, the authors mailed a four-page, 24-item survey to all 2,061 community-based primary care preceptors served by the North Carolina Area Health Education Centers system. The survey measured preceptor satisfaction, likelihood of continuing as a preceptor, influence of having students, motivation for teaching, satisfaction in professional practice, satisfaction with incentives, and value of incentives. Response rate was 69.3%, or 1,428 preceptors. Most preceptors (93.0%) reported high satisfaction with their precepting experience, and 90.9% indicated high likelihood of continuing to precept for the next five years. Almost all preceptors (93.7%) reported they were satisfied with their professional life. Many community preceptors (57.2%) were satisfied with incentives. They placed greater value on the intrinsic reasons for precepting (i.e., enjoyment of teaching) rather than extrinsic rewards (such as no-cost online library resources). Degree groups placed differing values on intrinsic and extrinsic rewards. Physicians reported more negativity about the influence of students and regarding aspects of their professional lives. Tailoring support to better meet individual degree groups' preferences can maximize resources and may encourage preceptor retention. Special attention to physicians' needs may be warranted to avoid decreased preceptor numbers in this at-risk group. Future studies are needed to determine whether these findings are unique to North Carolina, which has a strong infrastructure to support preceptors.

Benthic community structures in the North Sea

1995-03-01

Coherent assemblages of marine benthic species have been recognized from the early twentieth century, and the classical papers of Petersen (1914, 1918) were based on studies of limited areas in the North Sea. In 1986, a synoptic survey of the North Sea north to 57°N was undertaken by a group of ten laboratories from seven North Sea countries. The results of this survey have recently been published (Heip et al., 1992a, b; Künitzer et al., 1992; Huys et al., 1992), and some of the results are summarized in this paper. The analysis of the macrofauna is based on slightly more than 700 taxa. In general, the North Sea macrofauna consists of northern species extending south to the northern margins of the Dogger Bank, and southern species extending north to the 100 m depth line. The central North Sea is an area of overlap of southern and northern species, especially around the 70 m depth contour. Consistent groupings of species are recognized that were summarized in seven faunal groupings. Macrofaunal body weight, density and diversity increase linearly towards the north. Macrofaunal biomass for the whole area averages 7 g adwt. m-2 and decreases from south to north. Distribution patterns and trends within the meiofauna were very different. Nematodes, which are the dominant taxon overall, are least abundant in the sandy sediments of the Southern Bight, then increase to a maximum around 53° 30' N and slowly decrease again towards the north. Copepod density and diversity are highest in the Southern Bight, due to the presence of many interstitial species. A large number of species new to science were recorded by the North Sea Benthos Survey and about 1500 species are expected to occur. Copepods show very distinct assemblages according to water depth and sediment type. The contrasting patterns in latitudinal gradients of body weight and number of species of macro- and meiofauna can be only partially explained. Latitude and sediment characteristics, such as grain size and

Edible winkles from Saltom Bay, Cumbria (north-eastern Irish Sea) had flesh 210 Po concentrations in excess of 200 Bq kg -1 (wet). This came from liquid waste discharged under authorisation from a chemical plant producing phosphoric acid. This labelling of the winkles under natural conditions was exploited to determine the 210 Po depuration rate and biological half-time. Winkles transferred to Lowestoft and depurated in flowing seawater had biological half-times ranging from 82 to 119 days depending on temperature. After the chemical plant was shut, changes in Saltom Bay winkle flesh contents of 210 Po, 210 Pb and cadmium were followed by monthly samples. The biological half-time in the environment for the decrease in 210 Po after the plant closed was estimated at about 92 days. (author)

Mangrove forests in North Sumatera existed in the east coast of Sumatera Island and are rapidly threatened due to anthropogenic activities such as conversion for aquaculture, oil palm plantation, filling and use of mangrove for urban development. The present study describes the current and first-year evaluation on mangrove restoration and its impact to socio economic-cultural of community in Lubuk Kertang village, Langkat, North Sumatra, Indonesia. The rehabilitation was carried on December 2015 using direct planting of 6,000 Rhizophora apiculata propagules and May 2016 using 5,000 R. apiculata seedlings. The evaluation parameters of mangrove reforestation consist of seedling diameter and height, leaf thickness and number, and seedling growth rate. Ninety-two of 1,124 households were surveyed using Slovin formula to obtain community perspective on the socio-economic-cultural impact of reforestation. Results show that the growth rate for current and first-year evaluation was 93 and 86 %, respectively. By contrast, the height, diameter, and some leaves seedlings planting were shown better than the performance of propagules planting. No change in the green foliage plant thickness between both farming methods. The reforestation affected 71.74, 55.43 and 39.13% of economic, social, and cultural of Lubuk Kertang community, respectively. The data is likely to provide valuable information for mangrove reforestation in North Sumatra.

Transdisciplinarity Within the North American Climate Change Mitigation Research Community, Specifically the Carbon Dioxide Capture, Transportation, Utilization and Storage Community

Science.gov (United States)

Carpenter, Steven Michael

This research investigates the existence of and potential challenges to the development of a transdisciplinary approach to the climate change mitigation technology research focusing on carbon dioxide capture, utilization, and storage (CCUS) in North America. The unprecedented challenge of global climate change is one that invites a transdisciplinary approach. The challenge of climate change mitigation requires an understanding of multiple disciplines, as well as the role that complexity, post-normal or post-modern science, and uncertainty play in combining these various disciplines. This research followed the general discourse of transdisciplinarity as described by Klein (2014) and Augsburg (2016) which describe it as using transcendence, problem solving, and transgression to address wicked, complex societal problems, and as taught by California School of Transdisciplinarity, where the research focuses on sustainability in the age of post-normal science (Funtowicz & Ravetz, 1993). Through the use of electronic surveys and semi-structured interviews, members of the North American climate change mitigation research community shared their views and understanding of transdisciplinarity (Kvale & Brinkmann, 2009). The data indicate that much of the research currently being conducted by members of the North American CCUS research community is in fact transdisciplinary. What is most intriguing is the manner in which researchers arrived at their current understanding of transdisciplinarity, which is in many cases without any foreknowledge or use of the term transdisciplinary. The data reveals that in many cases the researchers now understand that this transdisciplinary approach is borne out of personal beliefs or emotion, social or societal aspects, their educational process, the way in which they communicate, and in most cases, the CCUS research itself, that require this transdisciplinary approach, but had never thought about giving it a name or understanding its origin or

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

Corrosion of metallic oilfield pipelines by microorganisms is a costly but poorly understood phenomenon, with standard treatment methods targeting mesophilic sulfatereducing bacteria. In assessing biocorrosion potential at an Alaskan North Slope oil field, we identified thermophilic hydrogen-using methanogens, syntrophic bacteria, peptideand amino acid-fermenting bacteria, iron reducers, sulfur/thiosulfate-reducing bacteria and sulfate-reducing archaea. These microbes can stimulate metal corrosion through production of organic acids, CO2, sulfur species, and via hydrogen oxidation and iron reduction, implicating many more types of organisms than are currently targeted. Micromolar quantities of putative anaerobic metabolites of C1-C4 n-alkanes in pipeline fluids were detected, implying that these low molecular weight hydrocarbons, routinely injected into reservoirs for oil recovery purposes, are biodegraded and provide biocorrosive microbial communities with an important source of nutrients.

Assessment of Particulate Matter Levels in Vulnerable Communities in North Charleston, South Carolina prior to Port Expansion

Directory of Open Access Journals (Sweden)

Erik R. Svendsen

2014-01-01

Full Text Available Introduction The Port of Charleston, one of the busiest US ports, currently operates five terminals. The fifth terminal is being planned for expansion to accommodate container ships from the proposed Panama Canal expansion. Such expansion is expected to increase traffic within local vulnerable North Charleston neck communities by at least 7,000 diesel truck trips per day, more than a 70% increase from the present average rate of 10,000 trucks per day. Our objective was to measure the current particulate matter (PM concentrations in North Charleston communities as a baseline to contrast against future air pollution after the proposed port expansion. Methods Saturation study was performed to determine spatial variability of PM in local Charleston neck communities. In addition, the temporal trends in particulate air pollution within the region were determined across several decades. With the BGI sampler, PM samples were collected for 24 hours comparable to the federal reference method protocol. Gravimetric analysis of the PM filter samples was conducted following EPA protocol. Results The range of the PM 10 annual average across the region from 1982 to 2006 was 17.0-55.0 μg/m 3 . On only two occasions were the records of PM 10 averaged above the 50.0 μg/m 3 national standard. In the case of PM 2.5 , the annual average for 1999-2006 ranged from 11.0 to 13.5 μg/m 3 and no annual average exceeded the 15.0 μg/m 3 PM 2.5 annual standard. Conclusions Although ambient PM levels have fallen in the Charleston region since the 1960s due to aggressive monitoring by the stakeholders against air pollution, local air pollution sources within the North Charleston neck communities have consistently contributed to the PM levels in the region for several decades. This baseline assessment of ambient PM will allow for comparisons with future assessments to ascertain the impact of the increased truck and port traffic on PM concentrations.

Exposure of birds to radionuclides and other contaminants in Special Protection Areas (SPAs) in North-West England

2010-01-01

There has been a decline in the population of some bird species at Morecambe Bay and the Solway Firth Special Protected Areas in North-West England during the last fifty years. It was suggested that the declines were caused, in part, by contaminants in the food and environment, primarily from the radioactive effluent discharge from the Sellafield Ltd nuclear fuel reprocessing plant in Cumbria. This study analysed bird feathers and tissues, vegetation and sediment for radionuclides, metals and persistent organic compounds. The non-radionuclide results were all low compared to relevant action limits. The ERICA model was used with field data to estimate the radiological dose to birds from exposure to 137 Cs and 241 Am with results between 1.26 to 3.83 μGy h -1 , below the ERICA screening level of 10 μGy h -1 and within the IAEA 40 μGy h -1 guideline value below which potential adverse impacts on biota are unlikely. The study showed no link between bird population decline and anthropogenic discharges to the SPAs.

Prussian carp ( Carassius gibelio ) are one of the most noxious non-native species in Eurasia. Recently, Prussian carp, a non-native freshwater fish species, were genetically confirmed in Alberta, Canada and have been rapidly expanding their range in North America since establishment. Given their rapid range expansion, there is an increasing need to determine how Prussian carp may impact native species. We assessed the severity of the Prussian carp invasion by (i) determining their impact on fish communities, (ii) assessing their impact on benthic invertebrate communities, (iii) evaluating if Prussian carp alter abiotic conditions, and (iv) identifying where we find higher abundances of Prussian carp. When Prussian carp were established, we found significant changes to the fish community. Correspondingly, the degree of impact to benthic invertebrate communities was related to the stage of invasion (none, early or recent), where changes in fish communities were significantly concordant with changes in benthic invertebrate communities. Finally, we found that higher abundances of Prussian carp were significantly associated with lower abundances of a majority of native fish species. Altogether, using three lines of evidence, we determine that Prussian carp can have wide-ranging impacts on freshwater ecosystems in North America, pressing the need for management intervention.

High amounts of driftwood sail across the oceans and provide habitat for organisms tolerating the rough and saline environment. Fungi have adapted to the extremely cold and saline conditions which driftwood faces in the high north. For the first time, we applied high-throughput sequencing to fungi residing in driftwood to reveal their taxonomic richness, community composition, and ecology in the North Atlantic. Using pyrosequencing of ITS2 amplicons obtained from 49 marine logs, we found 807 fungal operational taxonomic units (OTUs) based on clustering at 97 % sequence similarity cut-off level. The phylum Ascomycota comprised 74 % of the OTUs and 20 % belonged to Basidiomycota. The richness of basidiomycetes decreased with prolonged submersion in the sea, supporting the general view of ascomycetes being more extremotolerant. However, more than one fourth of the fungal OTUs remained unassigned to any fungal class, emphasising the need for better DNA reference data from the marine habitat. Different fungal communities were detected in coniferous and deciduous logs. Our results highlight that driftwood hosts a considerably higher fungal diversity than currently known. The driftwood fungal community is not a terrestrial relic but a speciose assemblage of fungi adapted to the stressful marine environment and different kinds of wooden substrates found in it.

Full Text Available Abstract Background Malaria is still prevalent in rural communities of central Vietnam even though, due to deforestation, the primary vector Anopheles dirus is uncommon. In these situations little is known about the secondary vectors which are responsible for maintaining transmission. Basic information on the identification of the species in these rural communities is required so that transmission parameters, such as ecology, behaviour and vectorial status can be assigned to the appropriate species. Methods In two rural villages - Khe Ngang and Hang Chuon - in Truong Xuan Commune, Quang Binh Province, north central Vietnam, a series of longitudinal entomological surveys were conducted during the wet and dry seasons from 2003 - 2007. In these surveys anopheline mosquitoes were collected in human landing catches, paired human and animal bait collections, and from larval surveys. Specimens belonging to species complexes were identified by PCR and sequence analysis, incrimination of vectors was by detection of circumsporozoite protein using an enzyme-linked immunosorbent assay. Results Over 80% of the anopheline fauna was made up of Anopheles sinensis, Anopheles aconitus, Anopheles harrisoni, Anopheles maculatus, Anopheles sawadwongporni, and Anopheles philippinensis. PCR and sequence analysis resolved identification issues in the Funestus Group, Maculatus Group, Hyrcanus Group and Dirus Complex. Most species were zoophilic and while all species could be collected biting humans significantly higher densities were attracted to cattle and buffalo. Anopheles dirus was the most anthropophilic species but was uncommon making up only 1.24% of all anophelines collected. Anopheles sinensis, An. aconitus, An. harrisoni, An. maculatus, An. sawadwongporni, Anopheles peditaeniatus and An. philippinensis were all found positive for circumsporozoite protein. Heterogeneity in oviposition site preference between species enabled vector densities to be high in both

Radionuclides in house dust

Energy Technology Data Exchange (ETDEWEB)

Fry, F A; Green, N; Dodd, N J; Hammond, D J

1985-04-01

Discharges of radionuclides from the British Nuclear Fuel plc (BNFL) reprocessing plant at Sellafield in Cumbria have led to elevated concentrations radionuclides in the local environment. The major routes of exposure of the public are kept under review by the appropriate authorising Government departments and monitoring is carried out both by the departments and by BNFL itself. Recently, there has been increasing public concern about general environmental contamination resulting from the discharges and, in particular, about possible exposure of members of the public by routes not previously investigated in detail. One such postulated route of exposure that has attracted the interest of the public, the press and Parliament arises from the presence of radionuclides within houses. In view of this obvious and widespread concern, the Board has undertaken a sampling programme in a few communities in Cumbria to assess the radiological significance of this source of exposure. From the results of our study, we conclude that, although radionuclides originating rom the BNFL site can be detected in house dust, this source of contamination is a negligible route of exposure for members of the public in West Cumbria. This report presents the results of the Board's study of house dust in twenty homes in Cumbria during the spring and summer of 1984. A more intensive investigation is being carried out by Imperial College. (author)

Engaging men as promotores de salud: perceptions of community health workers among Latino men in North Carolina.

Science.gov (United States)

Villa-Torres, Laura; Fleming, Paul J; Barrington, Clare

2015-02-01

The promotor de salud, or community health worker (CHW) role, is highly feminized and little is known about how men view their participation in CHW programs. We conducted in-depth interviews with Latino men in North Carolina to explore this gap. We used systematic coding and display procedures informed by Grounded Theory to analyze the data. Men described their communities as lacking cohesion, making integration of Latino immigrants difficult. Most did not consider themselves leaders or feel they had leaders in their communities. Their perceptions of the feminized CHW role as well as the volunteer or low-paid nature of CHW work conflicted with men's provider role. They also did not think they could perform the CHW role because they lacked education, skills, and broad networks. Efforts to increase male participation in CHW programs in new Latino immigrant destinations will need to understand and address these gender and migration-related dynamics in order to engage both women and men in improving the health of their communities.

Dementia RED (Respect Empathy Dignity): Collaborating to build dementia supportive communities in North Wales--reporting on a pilot project (innovative practice).

Science.gov (United States)

Chalk, Annabel; Page, Sean

2016-03-01

There is increasing interest in developing dementia supportive communities world wide. Dementia RED (Respect Empathy Dignity) is a unique example from North Wales which is based on the twin concepts of people living with dementia as citizens in their community and developing 'bottom up' rather than 'top down' approaches to dementia supportive communities. Most people with dementia prefer to live at home thus making community connectivity key to maintaining healthy relationships and wellbeing. For those living with dementia, the community plays a pivotal role in providing value, meaning, purpose and acceptance. Building dementia supportive communities helps to raise awareness about dementia in the community through engagement and from identifying champions in the locality to voice issues. Dementia RED is an initiative and service which helps to develop such a philosophy in creating a dementia supportive community. © The Author(s) 2014.

Microbial Communities in North American Ixodid Ticks of Veterinary and Medical Importance

Directory of Open Access Journals (Sweden)

Andrea S. Varela-Stokes

2017-10-01

Full Text Available Interest in microbial communities, or microbiota, of blood-feeding arthropods such as ticks (order Parasitiformes, suborder Ixodida is increasing. Studies on tick microorganisms historically emphasized pathogens of high medical or veterinary importance. Current techniques allow for simultaneous detection of pathogens of interest, non-pathogenic symbionts, like Coxiella-LE and Francisella-LE, and microorganisms of unknown pathogenic potential. While each generation of ticks begins with a maternally acquired repertoire of microorganisms, microhabitats off and on vertebrate hosts can alter the microbiome during the life cycle. Further, blood-feeding may allow for horizontal exchange of various pathogenic microbiota that may or may not also be capable of vertical transmission. Thus, the tick microbiome may be in constant flux. The geographical spread of tick vector populations has resulted in a broader appreciation of tick-borne diseases and tick-associated microorganisms. Over the last decade, next-generation sequencing technology targeting the 16S rRNA gene led to documented snapshots of bacterial communities among life stages of laboratory and field-collected ticks, ticks in various feeding states, and tick tissues. Characterizing tick bacterial communities at population and individual tissue levels may lead to identification of markers for pathogen maintenance, and thus, indicators of disease “potential” rather than disease state. Defining the role of microbiota within the tick may lead to novel control measures targeting tick-bacterial interactions. Here, we review our current understanding of microbial communities for some vectors in the family Ixodidae (hard ticks in North America, and interpret published findings for audiences in veterinary and medical fields with an appreciation of tick-borne disease.

Understanding communication pathways to foster community engagement for health improvement in North West Pakistan

Full Text Available Abstract Background This paper describes the community engagement process undertaken to ascertain the focus, development and implementation of an intervention to improve iodised salt consumption in rural communities in North West Pakistan. The Jirga is a traditional informal structure, which gathers men respected within their community and acts in a governing and decision-making capacity in the Pukhtoon culture. The Jirga system had a dual purpose for the study: to access men from the community to discuss the importance of iodised salt, and as an engagement process for the intervention. Methods A number of qualitative data collection activities were undertaken, with Jirga members and their wives, male and female outreach workers and two groups of women, under and over 40 years old. The aim of these was to highlight the communication channels and levers of influence on health behaviour, which were multiple and complex and all needed to be taken into consideration in order to ensure successful and locally sensitive community engagement. Results Communication channels are described within local families and the communities around them. The key influential role of the Jirga is highlighted as linked both to the standing of its members and the community cohesion ethos that it embodies. Engaging Jirga members in discussions about iodised salt was key in designing an intervention that would activate the most influential levers to decision making in the community. Gendered decision-making processes within the household have been highlighted as restricting women’s autonomy. Whilst in one respect our data confirm this, a more complex hierarchy of decisional power has been highlighted, whereby the concept of ‘wisdom’- an amalgamation of age, experience and education- presents important possibilities. Community members with the least autonomy are the youngest uneducated females, who rely on a web of socially and culturally determined ways to influence

North Alex mud volcano, located on the upper slope of the western Nile deep-sea fan, is characterized by an active seepage center transporting pore fluids, hydrocarbons and gases from deep subsurface sources to the sediment-water interface. Surface sediments feature steep temperature gradient of 8.5°C m-1. We sampled the top 40 cm of the sediments at different locations between the center and rim of the mud volcano to study the diversity, activity, and physiological characteristics of benthic microorganisms. The sediments revealed the activity of anaerobic oxidation of methane coupled to sulfate reduction with a mesophilic temperature optimum. Organisms involved in the process include consortia of methanotrophic archaea (ANME-2 group) and an unknown bacterial partner. Besides methanotrophic organisms the sediments harbored a variety of other bacterial and archaeal groups - including potentially thermophilic bacteria that could be involved in sulfur cycling. This poster presentation will provide an overview of microbial activities and community compositions of North Alex mud volcano sediments.

Community-based participatory research (CBPR) holds tremendous promise for addressing public health disparities. As such, there is a need for academic institutions to build lasting partnerships with community organizations. Herein we have described the process of establishing a relationship between a research university and a Black church in rural North Carolina. We then discuss Harvest of Hope, the church-based pilot garden project that emerged from that partnership. The partnership began with a third-party effort to connect research universities with Black churches to address health disparities. Building this academic-community partnership included collaborating to determine research questions and programming priorities. Other aspects of the partnership included applying for funding together and building consensus on study budget and aims. The academic partners were responsible for administrative details and the community partners led programming and were largely responsible for participant recruitment. The community and academic partners collaborated to design and implement Harvest of Hope, a church-based pilot garden project involving 44 youth and adults. Community and academic partners shared responsibility for study design, recruitment, programming, and reporting of results. The successful operation of the Harvest of Hope project gave rise to a larger National Institutes of Health (NIH)-funded study, Faith, Farming and the Future (F3) involving 4 churches and 60 youth. Both projects were CBPR efforts to improve healthy food access and reducing chronic disease. This partnership continues to expand as we develop additional CBPR projects targeting physical activity, healthy eating, and environmental justice, among others. Benefits of the partnership include increased community ownership and cultural appropriateness of interventions. Challenges include managing expectations of diverse parties and adequate communication. Lessons learned and strategies for building

Sclerotia are resting structures of ectomycorrhizal fungi and appear as a response to unfavorable environmental conditions such as desiccation. They are hard, black, comparatively smooth and mostly spherical. Sclerotia are formed in rhizosphere and the 14C ages of sclerotia from A horizons of volcanic ash soils may range from modern until ca. 100~1,200 yr B.P. Most sclerotia-forming fungal species are known to be host-specific plant pathogens and therefore their abundance may indicate the presence of their host plants. The purpose of this study was to investigate fungal communities in sclerotia with an interest in describing the existing or may have previously existed host plant community. To investigate fungal community inside of sclerotia by 16S rDNA gene clone library, several hundred of sclerotia (ca. 1g) were collected from Fagus crenata forest soil in north eastern Japan. The rDNA ITS regions were then amplified by the PCR using primer pair ITS-1F/ITS-4. Aliquots of the amplified DNA were digested with restriction endonucleases AluI, Hae III, and HhaI to obtain ITS-RFLPs. To obtain the fungal community profiles a quenching fluorescence primer was used for real-time quantitative PCR (qPCR) assay to monitor the PCR amplification and then used for T-RFLP. The predominant group determined by clone library analysis from the sclerotia was Ascomycota: Arthrinium arundinis, which has been reported to be one of the soil fungal species responsible for bamboo degradation and a pathogen for many species belonging to Poaceae family.

The author discusses the frustrations of the international community in dealing with North Korea after negotiation of the Nuclear Non-proliferation treaty. In the past, the international community has not been well prepared to deal with the North Korean obstinacy. It has repeatedly misjudged North Korean goals, South Korean Interests, and Japanese reactions. A new approach is proposed for the long run, that avoids coercion or appeasement. Economic incentives are suggested as the means to bring about changes in North Korean attitudes that will ultimately foster the desire for maintaining economic stability and well being rather than warlike independence. China and the former Soviet Union are not considered supportive of a warlike posture in North Korean but are making economic overtures to South Korea themselves. If the economic approach proves successful, it will enhance the chances of Korean unification by peaceful means and under democratic rule because time is on the side of democracy. In the long run nonproliferation will be achieved through unification.

Obesity is a prominent problem in the United States and in North Carolina. One way of combating it is with community-engaged interventions that foster collaboration between health-oriented organizations and community residents. Our purpose was to assemble a multifaceted group in Durham, North Carolina, to identify factors affecting obesity-related lifestyle behaviors; assess policies, resources, and the population's perception of the problem of obesity; and develop plans to improve health outcomes related to obesity. A team consisting of more than 2 dozen partners was assembled to form Achieving Health for a Lifetime (AHL) in order to study and address obesity in the community, initially focusing on elementary school-age children. The team developed a resource guide by collecting information by telephone interviews of provider organizations; geospatial resource maps were created using high-resolution geographic information systems, Duke's Data Support Repository, and county and city records; and focus groups were conducted using the nominal group technique. The AHL team, in collaboration with 2 other teams focused on diabetes and cardiovascular disease, identified 32 resources for diabetes, 20 for obesity, and 13 for cardiovascular disease. Using Geographic Information Systems (GIS), the team identified an area of Durham that had only 1 supermarket, but 34 fast-food restaurants and 84 convenience stores. The focus on particular neighborhoods means that the information obtained might not pertain to all neighborhoods. The AHL team was able to assemble a large community partnership in Durham that will allow the members of the community to continue to work toward making residents healthier. Communities facing similar challenges can learn from this experience.

Examination of community and consumer nutrition, tobacco and physical activity environments at food and tobacco retail stores in three diverse North Carolina communities

Full Text Available To advance our understanding of multiple health-related dimensions of the built environment, this study examined associations among nutrition, tobacco, and physical activity community and consumer environments. Community environment measures included supermarket access, tobacco outlet density, and physical activity resource density in store neighborhoods. Cross-sectional observations of the nutrition, tobacco and physical activity environments were conducted in 2011 at and around 303 food stores that sold tobacco products in three North Carolina counties. Pearson correlation coefficients and multiple linear regression were used to examine associations between community and consumer environments. Correlations between community nutrition, tobacco, and physical activity environments ranged from slight to fair (−0.35 to 0.20 and from poor to fair (−0.01 to −0.38 between consumer environments. Significant relationships between consumer tobacco and nutrition environments were found after controlling for store and neighborhood characteristics. For example, stores with higher amounts of interior tobacco marketing had higher healthy food availability (p = 0.001, while stores with higher amounts of exterior tobacco marketing had lower healthy food availability (p = 0.02. Community and consumer environments for nutrition, tobacco, and physical activity were interrelated. Measures that assess single aspects of community or consumer environments could miss characteristics that may influence customer purchasing. Even chain supermarkets, typically regarded as healthful food sources compared to smaller food stores, may expose customers to tobacco marketing inside. Future research could explore combining efforts to reduce obesity and tobacco use by addressing tobacco marketing, healthy food availability and physical activity opportunities at retail food outlets.

In the fall of 2014, the R/V Marcus Langseth collected gravity, magnetic, and reflection seismic data as part of the Eastern North American Margin Community Seismic Experiment. The dataset covers a 500 km wide section of the Mid-Atlantic passive margin offshore North Carolina, which formed after the Mesozoic breakup of the supercontinent Pangaea. Using these seismic and potential field data, we present observations and interpretations along two cross margin and one along-margin profiles. Analyses and interpretations are conducted using pre-stack depth migrated reflection seismic profiles in conjunction with forward modeling of shipboard gravity and magnetic anomalies. Preliminary interpretations of the data reveal variations in basement character and structure across the entire transition between continental and oceanic domains. These interpretations help provide insight into the origin and nature of the prominent East Coast and Blake Spur magnetic anomalies, as well as the Inner Magnetic Quiet Zone which occupies the domain between the anomalies. Collectively, these observations can aid in deciphering the rift-to-drift transition during the breakup of North America and West Africa and formation of the Central Atlantic.

High prevalence of physical inactivity contributes to adverse health outcomes. Active transportation (cycling or walking) is associated with better health outcomes, and bike-sharing programs can help communities increase use of active transportation. The Minneapolis Health Department funded the Nice Ride Minnesota bike share system to expand to the Near North community in Minneapolis, Minnesota. Near North is a diverse, low-income area of the city where residents experience health disparities, including disparities in physical activity levels. The installation of new bike share kiosks in Near North resulted in an environmental change to support physical activity. Community engagement was conducted pre-intervention only and consisted of focus groups, community meetings, and interviews. Postintervention data on bike share trips and subscribers were collected to assess intervention effectiveness. Focus group participants offered insights on facilitators and barriers to bike share and suggested system improvements. Community engagement efforts showed that Near North residents were positive about Nice Ride and wanted to use the system; however, the numbers of trips and subscriptions in Near North were low. Results show that the first season of the expansion was moderately successful in improving outreach efforts and adapting bike share to meet the needs of low-income populations. However, environmental change without adequate, ongoing community engagement may not be sufficient to result in behavior change.

This article describes a successful community-based partnership project between statutory and third-sector services targeting the strictly Orthodox Jewish community (OJC). The City and Hackney Black and Minority Ethnic (BME) Access Service (East London NHS Foundation Trust (ELFT)) collaborated with Bikur Cholim, a local third-sector organisation based in the heart of a north London Charedi OJC, to develop a brief culturally tailored psychoeducational group intervention focusing on mental health promotion and prevention. In total, 34 carers in the Charedi OJC were provided with general information on mental health, the availability of support services and self-care. Overall improvements in well-being, increased intentions to access services, particularly talking therapies, and qualitative feedback indicated that the group was very well received. The project endorses the value of culturally relevant psychoeducation, enabling suggestions for culturally appropriate service development.

Stakeholder participation for the legacy ponds and legacy silos (LP and LS) facility at Sellafield, Cumbria. UK: the nature and effectiveness of the dialogue - 16030

International Nuclear Information System (INIS)

Whitton, John

2009-01-01

The Legacy Ponds and Silos (LP and S) facilities are part of the UK nuclear legacy located at the Sellafield Site, Cumbria. There are four individual facilities containing nuclear wastes that have accumulated over a period of approximately 50 years. Waste retrieval and conditioning, in preparation for decommissioning, is currently being carried out by the site operator. LP and S have recently proposed a re-engagement with stakeholders following the initial engagement in December 2005. This paper reviews this earlier engagement in terms of the nature of dialogue that was carried out when compared against definitions of deliberation provided in the literature. The aim of this paper is to provide those planning future engagement with a better understanding of how the nature of dialogue can vary and uses participation and deliberation as indicators of effective engagement. A concern of those working towards a programme of effective stakeholder participation in 2005 was how to ensure genuine dialogue and stakeholder representation in such a strictly controlled and regulated environment with a technical complexity that challenges technical specialist and lay person alike. LP and S recognised that effective dialogue with stakeholders on the available technical options and their associated societal impacts would form a significant part of this process if options were to prove resilient. However, the challenge presented to LP and S was how to engage stakeholders on a variety of projects, whilst ensuring the output could be used by the projects as part of their technical decision making. Initial contact was made with stakeholders in December 2005, as part of a 'Baseline' Best Practicable Environmental Option (BPEO) study. A BPEO study leads to decisions on waste management based on an integrated assessment of alternative options, on the basis of factors such as the occupational and environmental risks, the environmental impacts, costs and social implications of the options

Feurer, D.A.; Weaver, C.L.

1981-01-01

A detailed description is presented of the laws and programs of the State of North Dakota governing the regulation of public energy utilities, the siting of energy generating and transmission facilities, the municipal franchising of public energy utilities, and the prescription of rates to be charged by utilities including attendant problems of cost allocations, rate base and operating expense determinations, and rate of return allowances. These laws and programs are analyzed to identify impediments which they may present to the implementation of Integrated Community Energy Systems (ICES). This report is one of fifty-one separate volumes which describe such regulatory programs at the Federal level and in each state as background to the report entitled Community Energy Systems and the Law of Public Utilities - Volume One: An Overview. This report also contains a summary of a strategy described in Volume One - An Overview for overcoming these impediments by working within the existing regulatory framework and by making changes in the regulatory programs to enhance the likelihood of ICES implementation.

Mangrove forests in North Sumatera, Indonesia existed in the east coast of Sumatera Island and commonly thrived in Langkat, Deli Serdang, Batubara, Tanjung Balai, Asahan, Labuhanbatu until Serdang Bedagai. The present study describes the developing community-based mangrove management (CBMM) through eco-tourism in two locations, Lubuk Kertang (LK) of Langkat and Sei Nagalawan (SN) of Serdang Bedagai, North Sumatra, Indonesia. Mangrove ecosystem, coastal villagers and visitors, and related stakeholder were analyzed to present the potential of mangrove ecosystem, the ecological suitability, and the carrying capacity then continued with SWOT (Strengths, Weaknesses, Opportunities, and Threats) analysis. Results showed that mangrove diversity in LK consist of fifteen species which Rhizophora apiculata and Avicennia lanata dominated the area, where mangroves in SN found seven species dominated by R. apiculata and A. officinalis. Based on the suitability level of mangrove ecosystem for ecotourism development, LK and SN were categorized as suitable and conditionally suitable, respectively. The carrying capacity of mangrove ecotourism for LK and SN were 36 and 36 people/day respectively. SWOT analysis revealed that both locations of eco-tourism have a potential eco-tourism attraction, high mangrove biodiversity, possible human resources, and real people’s perception on the importance of mangrove conservation, and relatively easy access. The study present suggested that mangrove ecotourism is a sustainable form of land use, to contributing the environmental protection and providing socio-economic benefits to the local people through indirect values of the natural resources.

CONFIGURATION OF CULTURAL NORMS IN TRADITIONAL RICE PLANTING RITUAL DISCOURSE THE TRADITIONAL FARMING COMMUNITY OF BAYAN, NORTH LOMBOK

I Made Netra

2015-01-01

Full Text Available This is the study of traditional rice planting ritual discourse of the traditional farming community of Bayan, North Lombok in an ethno-pragmatic perspective.  It is specifically aimed at describing the cultural norms and their meaning configurations.  The theory used in the study is the cultural scripts developed by Wierzbicka (2002a considering that cultural norms constitute rules and regulations in social interaction practices. They can be investigated from the use of grammatical aspects of language and linguistic routines which are context-bound. They can be configured by paraphrasing in simple and mini language using single space. The results of the study showed that there were some cultural norms found on the traditional rice planting ritual discourse of the traditional farming community of Bayan, North Lombok. They included: (1 asserting thought and hope, (2 respecting other entities, (3 apologizing, (4 promising, and (5 giving advice. The configuration of these cultural norms was in accordance with the understanding of local cultural scripts and wisdom in terms of rituals of the local farming system. The configuration is constructed in low-level script with components of “when” and “if”. It contains the aspects of thinking, speaking, and doing. It is derived from the semantic primes of both evaluation and perception.

The authors have reanalysed their previous data on the incidence of childhood malignancy in the North of England by very small geographical areas. Seascale, which ranks first by Poisson probability for all lymphoid malignancies is the village closest to the Sellafield plant. However, it is not unique in the region; nor are wards of apparent excess confined to coastal areas of Cumbria. The highest rate of lymphoid malignancies is in Whittingham, a village in north Northumberland. For other varieties of childhood cancer, there is a similar spread of 'Highly ranked', but different, wards throughout the region. (U.K.)

HIV/AIDS disproportionately affects minority groups in the United States, especially in the rural southeastern states. Poverty and lack of access to HIV care, including clinical trials, are prevalent in these areas and contribute to HIV stigma. This is the first study to develop a conceptual model exploring the relationship between HIV stigma and the implementation of HIV clinical trials in rural contexts to help improve participation in those trials. We conducted focus groups with HIV service providers and community leaders, and individual interviews with people living with HIV/AIDS in six counties in rural North Carolina. Themes related to stigma were elicited. We classified the themes into theoretical constructs and developed a conceptual model. HIV stigma themes were classified under the existing theoretical constructs of perceived, experienced, vicarious, and felt normative stigma. Two additional constructs emerged: causes of HIV stigma (e.g., low HIV knowledge and denial in the community) and consequences of HIV stigma (e.g., confidentiality concerns in clinical trials). The conceptual model illustrates that the causes of HIV stigma can give rise to perceived, experienced, and vicarious HIV stigma, and these types of stigma could lead to the consequences of HIV stigma that include felt normative stigma. Understanding HIV stigma in rural counties of North Carolina may not be generalizeable to other rural US southeastern states. The conceptual model emphasizes that HIV stigma--in its many forms--is a critical barrier to HIV clinical trial implementation in rural North Carolina.

Long-term temporal and spatial changes in the richness and relative abundance of the inshore fish community of the British North Sea Coast

Henderson, Peter A.

2017-09-01

Changes in temporal and spatial composition of the British inshore North Sea fish community are reviewed. Sampling from the cooling water filter screens of power stations bordering the North Sea commenced in the early 1960s. To date, a total of 112 marine fish species have been recorded, a high proportion of the total inshore fish species complement of shallow North Sea British waters. The unrecorded top predators, such as large sharks, swordfish and tuna are not regularly observed in waters fish diversity and abundance in large industrialised estuaries such as the Thames and the Firth of Forth. Linked to spawning and nursery habitat gain, smelt, Osmerus eperlangus, and bass, Dicentrarchus labrax, have greatly increased in abundance. There is no evidence for a decline in species richness since the 1970s. However, elasmobranch species number has declined while two species Raja clavata and Scyliorhinus canicula have remained abundant and one, Mustelus asterias, has increased in abundance. It is argued that overexploitation and habitat destruction remain, as they have been for the last 300 years, the most serious threats to the health of North Sea inshore fish communities. There are no clear signs that climate change is causing species loss, although it may be influencing relative species abundance as species at the southern edge of their range such as the viviparous blenny, Zoarces viviparous, have declined in the southern British North Sea. Power station water temperature records do not show a warming trend, in some estuarine locations temperature has declined with reduced thermal pollution; the temperature record cannot explain the observed major changes in fish relative abundance observed since the 1970s.

Community variability and ecological functioning: 40 years of change in the North Sea benthos.

Science.gov (United States)

Clare, D S; Robinson, L A; Frid, C L J

2015-06-01

Using established associations between species traits (life history, morphological and behavioural characteristics) and key ecological functions, we applied biological traits analysis (BTA) to investigate the consequences of 40 years of change in two North Sea benthic communities. Ecological functioning (trait composition) was found to be statistically indistinguishable across periods that differed significantly in taxonomic composition. A temporary alteration to functioning was, however, inferred at both sampling stations; coinciding with the North Sea regime shift of the 1980s. Trait composition recovered after 1 year at the station located inside the grounds of a trawl fishery, whereas the station located outside the main area of fishing activity underwent a six-year period of significantly altered, and temporally unstable, trait composition. A further alteration to functioning was inferred at the fished station, when the population of a newly established species rapidly increased in numbers. The results suggest that density compensation by characteristically similar (redundant) taxa acts to buffer changes to ecological functioning over time, but that functional stability is subject to aperiodic disruption due to substitutions of dissimilar taxa or uncompensated population fluctuations. The rate at which ecological functioning stabilises and recovers appears to be dependent on environmental context; e.g. disturbance regime. Copyright © 2015 Elsevier Ltd. All rights reserved.

Seasonal Changes in Microbial Community Structure in Freshwater Stream Sediment in a North Carolina River Basin

2014-01-01

Full Text Available This study examined seasonal differences in microbial community structure in the sediment of three streams in North Carolina’s Neuse River Basin. Microbes that reside in sediment are at the base of the food chain and have a profound influence on the health of freshwater stream environments. Terminal-Restriction Fragment Length Polymorphism (T-RFLP, molecular fingerprint analysis of 16S rRNA genes was used to examine the diversity of bacterial species in stream sediment. Sediment was sampled in both wet and dry seasons from an agricultural (Bear, mixed urban (Crabtree and forested (Marks Creek, and the microbiota examined. Gamma, Alpha and Beta proteobacteria were prevalent species of microbial taxa represented among all sites. Actinobacteria was the next most prevalent species observed, with greater occurrence in dry compared to the wet season. Discernable clustering was observed of Marks and Bear Creek samples collected during the wetter period (September–April, which corresponded with a period of higher precipitation and cooler surface water temperatures. Although not statistically significant, microbial community structure appeared different between season (ANOSIM, R = 0.60; p < 0.10. Principal components analysis confirmed this pattern and showed that the bacterial groups were separated by wet and dry seasonal periods. These results suggest seasonal differences among the microbial community structure in sediment of freshwater streams and that these communities may respond to changes in precipitation during wetter periods.

Unconventional natural gas (UNG) extraction (fracking) is ongoing in 29 North American shale basins (20 states), with ~6000 wells found within the Fayetteville shale (north-central Arkansas). If the chemical signature of fracking is detectable in streams, it can be employed to bookmark potential impacts. We evaluated benthic biofilm community composition as a proxy for stream chemistry so as to segregate anthropogenic signatures in eight Arkansas River catchments. In doing so, we tested the hypothesis that fracking characteristics in study streams are statistically distinguishable from those produced by agriculture or urbanization. Four tributary catchments had UNG-wells significantly more dense and near to our sampling sites and were grouped as 'potentially-impacted catchment zones' (PICZ). Four others were characterized by significantly larger forested area with greater slope and elevation but reduced pasture, and were classified as 'minimally-impacted' (MICZ). Overall, 46 bacterial phyla/141 classes were identified, with 24 phyla (52%) and 54 classes (38%) across all samples. PICZ-sites were ecologically more variable than MICZ-sites, with significantly greater nutrient levels (total nitrogen, total phosphorous), and elevated Cyanobacteria as bioindicators that tracked these conditions. PICZ-sites also exhibited elevated conductance (a correlate of increased ion concentration) and depressed salt-intolerant Spartobacteria, suggesting the presence of brine as a fracking effect. Biofilm communities at PICZ-sites were significantly less variable than those at MICZ-sites. Study streams differed by Group according to morphology, land use, and water chemistry but not in biofilm community structure. Those at PICZ-sites covaried according to anthropogenic impact, and were qualitatively similar to communities found at sites disturbed by fracking. The hypothesis that fracking signatures in study streams are distinguishable from those produced by other anthropogenic effects

2013-09-01

Full Text Available Phytoplankton diversity was investigated over a period of two years (2006 to 2008 in Chatla floodplain wetland in Barak valley, Assam, North-East India. Site 1 and site 2 are two inlets and site 3 is a lentic system associated with vegetation cover of Calamus tenuis and Baringtonia acutangula. The floodplain has a unique hydrology because of the presence of different types of habitats (inlets, fisheries, beels and outlets which maintains a network among the floodplains, rivers and streams. Phytoplankton community composition, density and diversity were studied in relation to environmental variables. All the variables were estimated by following standard methods. Phytoplankton was collected by plankton net and quantitative estimation was made by using Sedgwick Rafter counting cell. Phytoplankton community comprised 53 taxa represented by Chlorophyceae (31, Cyanophyceae (11, Bacillariophyceae (7, Euglenophyceae (1 and Dinophyceae (3. Phytoplankton taxa was dominated by Volvox sp., Nostoc sp., Eunotia sp., Navicula sp., Euglena spp. and density was found highest in site 3 and lowest in site 1. Shannon diversity index (H′ for phytoplankton community varied between 2.4 to 2.65 indicating fairly high species diversity. The varying magnitude of correlationship among environmental variables and phytoplankton species density as shown by Canonical correspondence analysis (CCA indicated that some of the environmental variables (water temperature, transparency, rainfall, nitrate and ammonia are the driving factors for governing the phytoplankton species assemblages in Chatla floodplain wetland. Fluctuation of phytoplankton density and community composition in different habitats indicated various niche apportionment as well as anthropogenic influences.

The relationship between rural community type and attachment to place for older people living in North Wales, UK.

Science.gov (United States)

Burholt, Vanessa; Naylor, Dawn

2005-06-01

This paper explores the relationship between rural community type and attachment to place for 387 older people aged 70 and over. Six rural settlements in North Wales are characterised according to certain statistics (e.g. age structure, in-migration, strength of local culture, and multiple deprivation) to provide distinct community profiles. It is hypothesised that community type is characterised by particular types of attachment, which are dependent on life course trajectories and changes or stability in the environment. Using a sevenfold classification of attachment to place, the paper tests seven hypotheses. The results support four of the seven hypotheses. Older people living in a retirement destination are more likely to report aesthetic qualities and the appropriateness of the environment. People living in native areas with a strong culture and local language are more likely to note the importance of historical attachment and social integration into the community. Three hypotheses are rejected: older people living in a retirement destination are not less likely to report social support, or a historical perspective in attachment to place, and older people living in areas with high levels of multiple deprivation are not more likely to encounter relocation restraints than are others. Overall, the findings suggest that the taxonomy of attachment to place provides a flexible framework for differentiation by community. The paper concludes that communities are not merely settings-they play a significant role in self-identity and are a vital source of emotional and experiential meaning for the inhabitant.

A Lagrangian approach based on a physical–biogeochemical modeling was used to compare the potential transfer of cadmium (Cd) from natural and anthropogenic sources to plankton communities (Cd-uptake) in the North-West African upwelling. In this region, coastal upwelling was estimated to be the main natural source of Cd while the most significant anthropogenic source for marine ecosystem is provided by phosphate industry. In our model experiment, Cd-uptake (natural or anthropogenic) in the North-West African upwelling is the result of an interplay between the Cd dispersion (by advection processes) and the simulated biological productivity. In the Moroccan waters, advection processes limit the residence time of water masses resulting in a low natural Cd-uptake by plankton communities while anthropogenic Cd-uptake is high. As expected, the situation is reversed in the Senegalo-Mauritanian upwelling where natural Cd-uptake is higher than anthropogenic Cd-uptake. Based upon an estimate of Cd sources, our modeling study shows, unexpectedly, that the anthropogenic signal of potential Cd-bioaccumulation in the Moroccan upwelling is of the same order of magnitude as the natural signal mainly present in the Senegalo-Mauritanian upwelling region. A comparison with observed Cd levels in mollusk and fishes, which shows overall agreement with our simulations, is confirming our estimates. - Highlights: • We model the physical–biogeochemical dynamics in the North-West African upwelling. • We model the transport of cadmium from natural and anthropogenic sources. • We derive proxies of potential cadmium absorption and bioaccumulation in the plankton food chain. • The anthropogenic signal off Morocco at least equals the natural upwelling signal off Mauritania. • We compare our results with observed cadmium levels in mollusks and fishes.

Lee, Seung-Keun

2011-01-01

This paper focuses on the North Korean nuclear crisis and how to find the best method of dismantling the North's nuclear facilities. From empirical studies of North Korean negotiating behavior, strategy, intentions and future of the regime, North Korea seems unlikely to abandon its nuclear program, if left unconstrained. This paper analyzes North Korean nuclear strategy and discusses problems concerned with the North Korean nuclear issues. It will propose some resolutions for a comprehensive approach in order to find a solution to the North Korean nuclear threat: restarting the six-party talks; preparation of a sophisticated nuclear elimination road-map; encouraging the gradual transformation of North Korea and its integration into the international community. In the long run, when North Korean nuclear strategy is considered, dialogue and engagement combined with international pressure or proper sanctions is needed

2008-01-01

A study of viability of alternative energy sources for typical communities of the North or Northeast of Brazil, which do not have access to the electric energy is performed. Brazil presents a great economic and social disparity among its several regions. There are several poor communities, mainly in regions far from big cities, without electrical energy. The Brazilian government has a program known as 'Luz para Todos' (Light for All). The big challenge of this program is to bring electrical energy for everyone using new alternatives energy sources. In this work initially a literature review was made concerning the following alternative energy source: wind, solar and biomass. These energy sources can be used to supply the demand to bring electrical energy for poor communities. For this work it is intended to choose a community that has population between 1,000 and 10,000 and does not have access to electrical energy. For this community an economic viability study will be made to evaluate alternative energy sources. The best energy source resulted from the point of view of the economic viability study will be implemented in that community. A new study will be performed to evaluate cost and environmental impact. In this new study the future social development of the community caused by the installation of electrical energy will be considered. Also, this best energy source will be compared with the new generation of nuclear reactors, for instance , the IRIS reactor. (author)

The objective of this work is to perform a study of viability of alternative energy sources for typical communities of the North or Northeast of Brazil, which do not have access to the electric energy. Brazil presents a great economic and social disparity among its several regions. There are several poor communities, mainly in regions far from big cities, without electrical energy. The Brazilian government has a program known as 'Luz para Todos' (Light for All). The big challenge for this program is to bring electrical energy for everyone using new alternatives energy sources. In this work initially a literature review was made concerning the following alternative energy sources: wind, solar and biomass. These energy sources can be used to supply the demand to bring electrical energy for poor communities. For this work it is intended to choose a community that has population between 1,000 the 10,000 and does not have access to electrical energy. For this community an economic viability study will be made to evaluate alternative energy sources. The best energy source resulted from the point of view of the economic viability study will be implemented in that community. A new study will be performed to evaluate cost and environmental impact. In this new study the future social development of the community caused by the installation of electrical energy will be considered. Also, this best energy source will be compared with the new generation of nuclear reactors, for instance, the IRIS reactor. (author)

The North American Carbon Program (NACP) was formed to further the scientific understanding of sources, sinks, and stocks of carbon in Earth's environment. Carbon cycle science integrates multidisciplinary research, providing decision-support information for managing climate and carbon-related change across multiple sectors of society. This investigation uses the conceptual framework of com-munities of practice (CoP) to explore the role that the NACP has played in connecting researchers into a carbon cycle knowledge network, and in enabling them to conduct physical science that includes ideas from social science. A CoP describes the communities formed when people consistently engage in shared communication and activities toward a common passion or learning goal. We apply the CoP model by using keyword analysis of abstracts from scientific publications to analyze the research outputs of the NACP in terms of its knowledge domain. We also construct a co-authorship network from the publications of core NACP members, describe the structure and social pathways within the community. Results of the content analysis indicate that the NACP community of practice has substantially expanded its research on human and social impacts on the carbon cycle, contributing to a better understanding of how human and physical processes interact with one another. Results of the co-authorship social network analysis demonstrate that the NACP has formed a tightly connected community with many social pathways through which knowledge may flow, and that it has also expanded its network of institutions involved in carbon cycle research over the past seven years.

In order to clarify the effects of tillage patterns on farmland weed community structure and crop production characteristics, based on 10 years location experiment with no-tillage, subsoiling and conventional tillage in the cold and arid region of North China, and supplementary experiment of plowing after 10 years no-tillage and subsoiling, oat was planted in 2 soils under different tillage patterns, and field weed total density, dominant weed types, weed diversity index, field weed biomass and oats yield were measured. The results showed that the regional weed community was dominated by foxtail weed (Setaira viridis); the weed density under long-term no-tillage was 2.20-5.14 times of tillage at different growing stages of oat, but there were no significant differences between conditional tillage and plowing after long-term no-tillage and subsoiling. Field weed Shannon diversity indices were 0.429 and 0.531, respectively, for sandy chestnut soil and loamy meadow soil under no-tillage conditions, and field weed biomass values were 1.35 and 2.26 times of plowing treatment, while the oat biomass values were only 2807.4 kg x hm(-2) and 4053.9 kg x hm(-2), decreased by 22.3% and 46.2%, respectively. The results showed that the weed community characteristics were affected by both tillage patterns and soil types. Long-term no-tillage farmland in the cold and arid region of North China could promote the natural evolution of plant communities by keeping more perennial weeds, and the plowing pattern lowered the annual weed density, eliminated perennial weeds with shallow roots, and stimulated perennial weeds with deep roots.

Condom use as part of the wider HIV prevention strategy: experiences from communities in the North West Province, South Africa.

Correct and consistent condom usage remains a pivotal strategy in reaching the target set by the South African government to reduce new HIV infections by 50% in the next 5 years. Studies have found that there has been an increase in condom usage by some categories of the population, but usage has not yet reached the desired levels in order to meet the target. This article reports on the findings of a study on condom usage in eight communities in the North West Province, which was part of a wider HIV and AIDS programme evaluation commissioned by the North West Provincial Department of Health. The main aim was to assess accessibility to condoms, and knowledge, attitudes and practices around condom use by four sampled communities in the North West Province. Eight focus group discussions were held and 50 households were interviewed. The study found positive results regarding accessibility and awareness of condoms. However, this often did not lead to the desired behavioural change of using condoms in risky sexual interactions. The majority of respondents still resisted condom usage, used condoms inconsistently, or were not in a position to negotiate protected sexual intercourse. The main reasons reported for this were: reduced pleasure, perceived and real physical side-effects, myths, lack of information, status, financial reasons, distrust in the efficacy of condoms, family planning, cultural reasons, gender-related reasons and trust. Many of the barriers to consistent condom use cannot be overcome by strategies that target the individual. Interventions need to address underlying developmental factors such as the non-biological factors that increase the susceptibility of women to HIV infection. As this falls outside of the scope of the mandate of the Department of Health, various partnerships with other key role players need to be established and/or strengthened, such as with local government, non-governmental organisations and faith-based organisations.

There is no doubt about the importance of North Sea oil to the energy supply of the European Community. One might however be used to it and forget about the nature and the size of its impact on our economies. Firstly, this paper intends to estimate this impact - past, present and future. Secondly, a more qualitative approach will explore possible consequences of the implementation of the internal market for North Sea oil. Thirdly, the assistance given by the Community to innovative technologies which enabled North Sea oil to contribute, under better economic conditions and within a safer environment, to our supply is recalled. And finally, some remarks on energy policy form an EC perspective, are offered. (author)

Currents in the Eastern Irish Sea

Howarth, M.J.

Low level radioactive waste is discharged from the nuclear re-processing plant at Sellafield, Cumbria. Its movement away from the discharge point is determined by the Irish Sea's dynamics, both for the soluble compounds and for those compounds which become attached to the sediment. Near Sellafield the tidal currents are weak and parallel to the shore, becoming stronger east/west to the north and south of the Isle of Man. Wind driven currents near Sellafield are predominantly north-westward, strongest near the coast, and oppose the other low frequency currents. Hence, the soluble effluent will initially be dispersed parallel to the shore by the weak tidal currents, moving episodically, southeastward during weak winds and northwestward during storms. Eventually it will leave the Irish Sea, flowing northward through the North Channel. (author)

This presentation discussed low carbon communities that used a variety of sustainable energy technologies to reduce energy consumption and waste. The presentation was given by a company who has adopted a One Planet framework to ensure the development of zero carbon, zero waste, sustainable communities.The Dockside Green project was awarded North America's highest leadership in energy and environmental design (LEED) score. The community includes a waste biomass plant and an on-site wastewater treatment plant. Excess heat produced by the community's greenhouse gas (GHG) neutral biomass district heating system is sold to neighbouring communities. The BedZED project in the United Kingdom uses a high-density format to support a community living and workspace environment that uses rainwater harvesting, passive solar heating, high performance envelopes, and green roofs. The site includes 40 electric car charging stations. A combined heat and power (CHP) biomass plant provides electricity and hot water to all buildings. Neighbourhood-scale sustainable development is expected to have a significant impact on the ecological footprint of North American cities. Carbon neutral projects in Canada were also listed. tabs., figs.

The 12-month Healthy Foods North intervention program was developed to improve diet among Inuit and Inuvialuit living in Arctic Canada and assess the impact of the intervention established for the communities. A quasi-experimental study randomly selected men and women (≥19 years of age) in six remote communities in Nunavut and the Northwest Territories. Validated quantitative food frequency and adult impact questionnaires were used. Four communities received the intervention and two communities served as delayed intervention controls. Pre- and post-intervention changes in frequency of/total intake of de-promoted food groups and healthiness of cooking methods were determined. The impact of the intervention was assessed using analysis of covariance (ANCOVA). Post-intervention data were analysed in the intervention (n = 221) and control (n = 111) communities, with participant retention rates of 91% for Nunavut and 83% for the Northwest Territories. There was a significant decrease in de-promoted foods, such as high fat meats (-27.9 g) and high fat dairy products (-19.8 g) among intervention communities (all p ≤ 0.05). The use of healthier preparation methods significantly increased (14.7%) in intervention communities relative to control communities. This study highlights the importance of using a community-based, multi-institutional nutrition intervention program to decrease the consumption of unhealthy foods and the use of unhealthy food preparation methods.

North Korea: a mercenary proliferator?

International Nuclear Information System (INIS)

Hemez, Remy

2015-01-01

After having recalled that North Korea possesses a rather advanced ballistic programme which has been started in the 1970 with the Chinese support, that North Korea is the fourth world producer of ballistic missiles, the author outlines that this country has become a major proliferator as it exports this production to different States and non-State actors. He recalls the long history of relationships between North Korea and terrorist organisations (even during the Cold War), comments the current and major support of North Korea to Hamas and Hezbollah in Gaza and in Lebanon. These relationships are then related with those these both organisations have with Syria and Iran who are in fact the relays between them and North Korea. The author explains why Hamas and Hezbollah must buy their weapons to such a far country: Iran is submitted to international sanctions, Iran and Syria want to avoid being banned from the international community for selling weapon to a terrorist (or so-said) organisation, and prices are rather competitive. If North Korea is also submitted to international sanctions, weapon smuggling seems to be institutional in this country. The author finally briefly evokes the issue of chemical weapons: North Korea possesses few thousand tonnes of these weapons, and could export them to non-state organisations

Energy policy of North Korea

Rueth, G.

2006-01-01

Since the year 1990, North Korea suffers internal-policy problems as well as foreign-political problems. The gross domestic investment decreased by 3.8% yearly between the years 1990 and 1998. Many actual problems of North Korea correspond with the energy crisis in this land affecting nearly all sectors of economy and society. This energy crisis was released by the fact, that the former Soviet Union has stopped the supply of primary energy in the year 1991. In the contribution under consideration, the author reports on the energy policy of North Korea. The main themes of this contribution are: (a) Development and characteristics of the energy sector; (b) Crisis of the energy sector; (c) Consequences of the energy crisis in North Korea; (d) Possibilities of the solution of the energy crisis. For the U.S.A. and the international community, the energy crisis offers the possibility to turn North Korea to negotiations by means of remedial measures in the energy sector. In response, North Korea should drop its nuclear energy program. Apart from such positive incentives, the threat of sanctions is conceivable. North Korea imports nearly 70 % of its oil demand from the People's Republic of China. Therefore, China has an great influence on North Korea. The energy crisis of North Korea shows the fatal consequences of a falsely performed energy policy with respect to the population of this land and with respect to the stability and disposing capacity of the political leadership

Insights into the benthic communities response to the inflow of Black Sea mesotrophic waters in the North Aegean Sea

The effects of the Dardanelles inflow of buoyant, modified Black Sea waters (BSW) of low salinity and temperature, on the meio- and macrobenthic communities of the north Aegean ecosystem was investigated during two cruises in October 2013 and March 2014. Sediment samples were collected from two stations subjected to the BSW effect, one shallow and one deep north of the Dardanelles Straits, and from two stations of similar bathymetry, which were considered to be outside the influence of BSW and were located to the south of the Dardanelles Straits. Results suggest that there is an effect of the BSW on benthos, as both meiofaunal and macrofaunal standing stocks were lower at the most distant, and therefore least affected from the inflow, station, and higher at the station of similar bathymetry which was affected the most by the BSW inflow. Univariate and multivariate non-parametric analyses (nMDS, PERMANOVA) provided further support, indicating differences between the two areas (North vs. South) in the case of the deep stations, while differences between depth categories were evident in the area outside the BSW influence zone. Distance-based linear modeling (DISTLM) indicated that meiofauna correlated with proxies of food availability and sediment characteristics. Macrofauna, on the other hand, showed a rather high significant correlation with depth only. Nematode species composition was statistically significant different between depth categories only, yet the nMDS ordination clearly separated the deep southern station from the rest, with non-selective deposit feeders dominating the stations under the influence of the BSW, and epistratum feeders being important at the stations outside the influence of the BSW. It is concluded that both the meiofaunal and macrofaunal communities at the northern stations benefit from a constant input of high amounts of organic matter to the seafloor, while those at the southern area may be occasionally affected by the thermohaline BSW

Factors that promote success in women enrolled in STEM disciplines in rural North Carolina community colleges

Science.gov (United States)

Kincaid, Shannon D.

Women have historically been underrepresented in the fields of science, technology, engineering, and math (STEM fields). The underrepresentation of women in STEM may be attributable to a variety of factors. These may include different choices men and women typically make in response to incentives in STEM education. For example, STEM career paths may be less accommodating to people who are less resilient. Another factor may be that there are relatively few female STEM role models. Perhaps strong gender stereotypes discourage women from pursuing STEM education and STEM jobs. The factors that contribute to success and the barriers that impeded success must be identified before any steps can be taken to improve the educational outcomes for women in STEM disciplines. Consequently, relatively little is known about the role of resilience in academically successful adult women in rural community colleges enrolled in STEM disciplines and the mechanisms that underlie the performance deficits that occur as a result of stereotype threat effect. This mixed method study addressed those knowledge gaps by determining: (1) if high resilience is positively correlated to high grade point average for women enrolled in STEM disciplines in rural community colleges in North Carolina, and (2) if stereotype threat effect is a risk factor for these women. Quantitative data were collected by using "The Resilience Scale" (Wagnild & Young, 1987) and through examination of grade point average of students from Datatel data management software. Qualitative data were collected through semi-structured focus group interviews. Findings from this study indicate high resilience is positively correlated to high grade point average for women enrolled in STEM disciplines in rural community colleges in North Carolina, and stereotype threat effect was a risk factor for low-scoring women (i.e. those women who reported resilience scores less than 121 and grade point averages lower than 2.70) and was not a

Colorectal cancer (CRC) is a leading cause of death among Hispanics in the United States. Despite the benefits of CRC screening, many Hispanics are not being screened. Using a combined methodology of focus groups and discrete choice experiment (DCE) surveys, the objectives for this research were as follows: (1) to improve understanding of preferences regarding potential CRC screening program characteristics, and (2) to improve understanding of the barriers and facilitators around CRC screening with the Hispanic, immigrant community in North Carolina. Four gender-stratified focus groups were conducted and DCE surveys were administered to 38 Spanish-speaking individuals across four counties in North Carolina. In-depth content analysis was used to examine the focus group data; descriptive analyses and mean attribute importance scores for cost of screening and follow-up care, travel time, and test options were calculated from DCE data. Data analyses showed that this population has a strong interest in CRC screening but experience barriers such as lack of access to resources, cost uncertainty, and stigma. Some of these barriers are unique to their cultural experiences in the United States, such as an expressed lack of tailored CRC information. Based on the DCE, cost variables were more important than testing options or travel time. This study suggests that Hispanics may have a general awareness of and interest in CRC screening, but multiple barriers prevent them from getting screened. Special attention should be given to designing culturally and linguistically appropriate programs to improve access to healthcare resources, insurance, and associated costs among Hispanics.

Food access interventions are promising strategies for improving dietary intake, which is associated with better health. However, studies examining the relationship between food access and intake are limited to observational designs, indicating a need for more rigorous approaches. The Veggie Van (VV) program was a cluster-randomized intervention designed to address the gap between food access and intake. In this article, we aim to describe the approaches involved in recruiting community partners to participate in VV. The VV mobile market aimed to improve access to fresh fruits and vegetables by providing subsidized, high-quality, local produce in low-resource communities in North Carolina. This study describes the strategies and considerations involved in recruiting community partners and individual participants for participation in the VV program and evaluation. To recruit partners, we used various strategies, including a site screener to identify potential partners, interest forms to gauge future VV use and prioritize enrollment of a high-need population, marketing materials to promote VV, site liaisons to coordinate community outreach, and a memorandum of understanding between all invested parties. A total of 53 community organizations and 725 participants were approached for recruitment. Ultimately, 12 sites and 201 participants were enrolled. Enrollment took 38 months, but our approaches helped successfully recruit a low-income, low-access population. The process took longer than anticipated, and funding constraints prevented certain strategies from being implemented. Recruiting community partners and members for participation in a multi-level, community-based intervention was challenging. Strategies and lessons learned can inform future studies.

Third North Korean nuclear test: what is the state of the North's programme?

International Nuclear Information System (INIS)

Sitt, Bernard

2013-02-01

Two months ago, following North Korea's Unha-3 launch, which put a small satellite into orbit, this publication discussed the possibility of a third North Korean nuclear test. As expected, Pyongyang remained true to its traditional policy of provocation. With carefully calculated timing, it carried out a third nuclear test on 12 February, just hours after Barack Obama's State of the Union address, four days before former leader Kim Jong-il's birthday, and on the eve of the investiture of the new South Korean president on the 25 February. Moreover, the North Korean regime is billing this test as a riposte to the new round of sanctions adopted on by the Security Council on 22 January following the Unha-3 launch in December, as it announced on the 24 January. Yet, aside from the associated posturing, this test confirms, if more confirmation were needed, the North's determination to develop an effective nuclear deterrent. The use of the term miniaturisation is certainly in part a propaganda exercise (can actual miniaturisation be achieved after three nuclear tests, one or two of whose success is highly doubtful?). Nonetheless, North Korea has clearly made progress in developing a nuclear weapon and an intercontinental ballistic missile derived from the Taepodong-2, and has promised to carry out further ballistic launches. Without a doubt, even if the North is a long way from possessing what we would consider an operational nuclear capability, its determination has helped it to make progress, and the country shows no signs of wanting to change course. In light of this fact, what can the international community do beyond existing and future sanctions regimes? Doubtless very little. China, which continues to support the North and which has been known in the past to exert influence on Pyongyang, has expressed its firm displeasure as to the North's activities but appears to have no leverage over Kim Jong-un. The Six-Party talks have little chance of being revived, as North

A study has been made of the radionuclide content of lake sediments from Cumbria in order to determine the history of discharges of /sup 137/Cs and actinides from the Sellafield works of British Nuclear Fuels plc (BNFL). Sediment cores have been taken from Ullswater and Grasmere, which are remote from Sellafield, in order to establish the behaviour of nuclear weapon fallout nuclides. Cores have also been taken from Barfield Tarn, which is 19 km SE of Sellafield but close to the sea, and from Ponsonby and Harnsey Moss Tarns, close to Sellafield. All sediments were analysed for /sup 137/Cs and sup(239+240)Pu. Additional measurements of /sup 238/Pu and /sup 241/Am were made on samples from the closer tarns. The sediment cores were dated by the /sup 210/Pb method and, where appropriate, by the /sup 137/Cs technique also. The amounts of /sup 137/Cs and sup(239+240)Pu in sediments from Barfield Tarn could be accounted for by fallout from nuclear weapons, although the levels of /sup 241/Am were marginally greater. However in Harnsey Moss Tarn the levels of actinides indicated that they were derived mainly from material originally discharged to sea from Sellafield. Sediment from Ponsonby Tarn contained material derived mainly from discharges to atmosphere.

There is a lack of information on the disease burden due to Taenia solium taeniasis and its associated risk factors in pig farming communities throughout the world. The present study was conducted in a rural pig farming community of north India to estimate the prevalence of T. solium taeniasis and associated factors. Demographic, clinical and epidemiological data were collected from 1181 subjects in 210 households in 30 villages. Stool specimens from 924 subjects were examined for eggs of Taenia and other parasites. Identification of T. solium was confirmed by morphological features of segments and species-specific DNA detection from segments and stool. The prevalence of T. solium taeniasis was 18.6% (172/924); factors associated with taeniasis on multivariate analysis were age above 15 years, history of passage of Taenia segments in stool, undercooked pork consumption and poor hand hygiene (hand-washing with clay/water after defecation). Seventy-eight subjects (6.6%) with epilepsy were identified. The study showed alarmingly high rates of epilepsy and T. solium taeniasis in the study community; it highlights the need for large-scale imaging-based surveys to identify the factors associated with epilepsy including neurocysticercosis. Health education, mass anthelminthic therapy and other preventive measures are required to control the menace of the disease.

A health-promoting community dental service in Melbourne, Victoria, Australia: protocol for the North Richmond model of oral health care.

2017-10-01

Despite the best efforts and commitment of oral health programs, there is no evidence that the current surgical output-based model of oral health care is delivering better oral health outcomes to the community. In fact, Australian evidence indicates the oral health of the community could be getting worse. It is now well-understood that this traditional surgical model of oral health care will never successfully manage the disease itself. It is proposed that a health-promoting, minimally invasive oral disease management model of care may lead to a sustainable benefit to the oral health status of the individual and community groups. The aim of this paper is to describe such a model of oral health care (MoC) currently being implemented by the North Richmond Community Health Oral Health (NRCH-OH) program in Melbourne, Victoria, Australia; this model may serve as a template for other services to re-orient their healthcare delivery towards health promotion and prevention. The paper describes the guiding principles and theories for the model and also its operational components, which are: pre-engagement while on the waitlist; client engagement at the reception area; the assessment phase; oral health education (high-risk clients only); disease management; and reviews and recall.

GoNorth! is an adventure learning series developed at the University of Minnesota in collaboration with NOMADS Online Expeditions. GoNorth! uses real-time experiences of dogsled expeditions on a multimedia saturated website at http://www.PolarHusky.com to motivate and engage millions of K-12 students and teachers. The program is free and research (Doering & Veletsianos, 2007) shows that it can be adopted by any teacher who signs up to use the program. It is currently utilized in 3400+ classrooms across the 50 US States and in 29 countries worldwide. Research (Doering & Veletsianos, 2007; 2008) notes that students working with GoNorth! are excited, motivated, and eager to engage with authentic tasks, solve real-world problems, collaborate with colleagues and experts, and initiate actions in their own community. Our team of educators, scientists and explorers circumnavigate the Arctic traveling by dog team to a new Arctic locale every year. Driven by an environmental question of particular relevance to the given Arctic region, each year a comprehensive natural and social science GoNorth! Curriculum & Activity Guide (450+ pages) is developed reflecting the expedition's current Arctic locale and its indigenous culture. The associated online learning environment delivers comprehensive resources about the region of travel, collaborative opportunities, live field updates and field research findings synched real-time to the curriculum. Field research relevant to understanding patterns of climate change and polar science is conducted with independent researchers featured as "Cool GoNorth! Scientists." Collaborations span from scientists at NASA and the United States Department of Agriculture to student observers in pan-Arctic communities as part of the NSF-supported initiative "What Is Climate Change to You?." This scientific research and fieldwork in turn coincides with the curriculum. The result is a community of learners on the Internet gaining knowledge from Arctic

2013-04-01

Full Text Available We describe and illustrate the biogeography of the cicadas inhabiting continental North America, north of Mexico. Species distributions were determined through our collecting efforts as well as label data from more than 110 institutional collections. The status of subspecies is discussed with respect to their distributions. As we have shown over limited geographic areas, the distribution of individual species is related to the habitat in which they are found. We discuss the biogeography of the genera with respect to their phylogenetic relationships. California is the state with the greatest alpha diversity (89 species, 46.6% of taxa and unique species (35 species, 18.3% of taxa. Texas, Arizona, Colorado and Utah are the states with the next greatest alpha diversity with Texas, Arizona and Utah being next for unique species diversity. Maine, New Hampshire and Rhode Island are the states with the least amount of cicada diversity. Diversity is greatest in states and areas where there is a diversity of plant communities and habitats within these communities. Mountainous terrain also coincides with increases in diversity. Several regions of the focus area require additional collection efforts to fill in the distributions of several species.

The ecosystem approach to management requires the status of individual species to be considered in a community context. We conducted a comparative ecosystem analysis of the Georges Bank and North Sea fish communities to determine the extent to which biological diversity is restored when fishing pressure is reduced. First, fishing mortality estimates were combined to quantify the community-level intensity and selectivity of fishing pressure. Second, standardized bottom-trawl survey data were used to investigate the temporal trends in community metrics. Third, a size-based, multispecies model (LeMans) was simulated to test the response of community metrics to both hypothetical and observed changes in fishing pressure in the two communities. These temperate North Atlantic fish communities have much in common, including a history of overfishing. In recent decades fishing pressure has been reduced, and some species have started to rebuild. The Georges Bank fishery has been more selective, and fishing pressure was reduced sooner. The two communities have similar levels of size diversity and biomass per unit area, but fundamentally different community structure. The North Sea is dominated by smaller species and has lower evenness than Georges Bank. These fundamental differences in community structure are not explained by recent fishing patterns. The multispecies model was able to predict the observed changes in community metrics better on Georges Bank, where rebuilding is more apparent than in the North Sea. Model simulations predicted hysteresis in rebuilding community metrics toward their unfished levels, particularly in the North Sea. Species in the community rebuild at different rates, with smaller prey species outpacing their large predators and overshooting their pre-exploitation abundances. This indirect effect of predator release delays the rebuilding of community structure and biodiversity. Therefore community rebuilding is not just the sum of single

Discharges of radionuclides from the British Nuclear Fuel plc (BNFL) reprocessing plant at Sellafield in Cumbria have led to elevated concentrations radionuclides in the local environment. The major routes of exposure of the public are kept under review by the appropriate Government departments and monitoring is carried out both by the departments and by BNFL itself. Recently, there has been increasing public concern about general environmental contamination resulting from the discharges and, in particular, about possible exposure of members of the public by routes not previously investigated in detail. One such postulated route of exposure that has attracted the interest of the public, the press and Parliament arises from the presence of radionuclides within houses. In view of this obvious and widespread concern, the Board has undertaken a sampling programme in a few communities in Cumbria to assess the radiological significance of this source of exposure. From the results of our study, we conclude that, alt...

This paper will first of all deal with a scenario in which a radiation hazard arises within the DPH's Health District and, building on this, will go on to consider a modified role for the Community Physician where a hazard arises outside his District but poses some threat to it. The submissions made on the role of the Community Physician as Director of Public Health of a District Health Authority are based on experience of exercises conducted over recent years in relation to a possible incident at Sellafield in West Cumbria.

Full Text Available Tobacco smoking is a major health issue for Indigenous Australians, however there are few interventions with demonstrated efficacy in this population. The Transtheoretical Model may provide a useful framework for describing smoking behaviour and assessing readiness to quit, with the aim of developing better interventions. Interviews were conducted with 593 Indigenous Australians in eight rural and remote communities in north Queensland, to examine stages of change and smoking behaviour. Among current smokers, 39.6% and 43.4% were in Precontemplation and Contemplation stages respectively. A further 13.9% were making preparations to quit (Preparation whilst only 3.2% said they were actively trying to quit (Action. When analysed by stage of change, the pattern of smoking-related behaviours conformed to the results of past research using the model. Importantly however, distribution of individuals across the stages opposes those observed in investigations of smoking behaviour in non-Indigenous Australian populations. The Transtheoretical Model can be used to meaningfully classify Indigenous smokers in remote north Queensland according to stages along the behaviour change continuum. Importantly, in this large sample across eight communities, most Indigenous smokers were not making preparations to change their smoking behaviour. This suggests that interventions should focus on promoting movement toward the Preparation and Action stages of change.

A comprehensive analysis on seasonal distribution of phytoplankton community structure and their interaction with environmental variables was carried out in two local water types (type 1  30 m isobath) at a coastal site in north-western Bay of Bengal. Phytoplankton community was represented by 211 taxa (146 marine, 37 fresh, 2 brackish, 20 marine-fresh, and 6 marine-brackish-fresh) belonging to seven major groups including 45 potential bloom forming and 22 potential toxin producing species. The seasonal variability depicted enrichment of phytoplankton during pre-monsoon in both water types. Total phytoplankton abundance pattern observed with inter-annual shift during monsoon and post-monsoon period at both water types. In both water types, diatom predominance was observed in terms of species richness and abundance comprising of centric (82 sp.) and pennate (58 sp.) forms. Pennate diatoms, Thalassiothrix longissima and Skeletonema costatum preponderated in both the water types. The diatom abundance was higher in type 1 in comparison to type 2. In general, SiO4 found to fuel growth of the dominant phytoplankton group, diatom in both the water types despite comparative lower concentration of other macronutrients in type 2.

Epilepsy is one of the most common neurological disorders prevalent in childhood period. There is scarcity of epidemiological data, required to plan services in resource constrained developing nations. To study the prevalence and treatment gap in childhood epilepsy in north Indian city, in the age group of 1-18 years. A two stage stratified cluster sampling; probability proportionate to size (PPS) was employed. A ten question screening questionnaire was employed to identify the presence of epilepsy. Definitions provided by International League against Epilepsy (ILAE) were used to classify screen positive subjects as epilepsy and to calculate the treatment gap. The prevalence rate for epilepsy was 6.24/1000 population. Febrile seizures and neurocysticercosis were most common causes of symptomatic seizures in childhood. This study of epidemiology of epilepsy provides valuable aid in optimizing effective community approach, thereby improving outcomes of childhood epilepsy.

Increases in obesity and other chronic conditions continue to fuel efforts for lifestyle behavior changes. However, many strategies do not address the impact of environment on lifestyle behaviors, particularly healthy dietary intake. This study explored the perceptions of environment on intake of fruits and vegetables in a cohort of 2,479 people recruited from 22 family practices in North Carolina. Participants were administered a health and social demographic survey. Formative assessment was conducted on a subsample of 32 people by using focus groups, semistructured individual interviews, community mapping, and photographs. Interviews and discussions were transcribed and content was analyzed using ATLAS.ti version 5. Survey data were evaluated for means, frequencies, and group differences. The 2,479 participants had a mean age of 52.8 years, mean body mass index (BMI) of 29.4, and were predominantly female, white, married, and high school graduates. The 32 subsample participants were older, heavier, and less educated. Some prevalent perceptions about contextual factors related to dietary intake included taste-bud fatigue (boredom with commonly eaten foods), life stresses, lack of forethought in meal planning, current health status, economic status, the ability to garden, lifetime dietary exposure, concerns about food safety, contradictory nutrition messages from the media, and variable work schedules. Perceptions about intake of fruits and vegetables intake are influenced by individual (intrinsic) and community (extrinsic) environmental factors. We suggest approaches for influencing behavior and changing perceptions using available resources.

Aim The fossil record has led to a historical explanation for forest diversity gradients within the cool parts of the Northern Hemisphere, founded on a limited ability of woody angiosperm clades to adapt to mid-Tertiary cooling. We tested four predictions of how this should be manifested in the phylogenetic structure of 91,340 communities: (1) forests to the north should comprise species from younger clades (families) than forests to the south; (2) average cold tolerance at a local site should be associated with the mean family age (MFA) of species; (3) minimum temperature should account for MFA better than alternative environmental variables; and (4) traits associated with survival in cold climates should evolve under a niche conservatism constraint. Location The contiguous United States. Methods We extracted angiosperms from the US Forest Service's Forest Inventory and Analysis database. MFA was calculated by assigning age of the family to which each species belongs and averaging across the species in each community. We developed a phylogeny to identify phylogenetic signal in five traits: realized cold tolerance, seed size, seed dispersal mode, leaf phenology and height. Phylogenetic signal representation curves and phylogenetic generalized least squares were used to compare patterns of trait evolution against Brownian motion. Eleven predictors structured at broad or local scales were generated to explore relationships between environment and MFA using random forest and general linear models. Results Consistent with predictions, (1) southern communities comprise angiosperm species from older families than northern communities, (2) cold tolerance is the trait most strongly associated with local MFA, (3) minimum temperature in the coldest month is the environmental variable that best describes MFA, broad-scale variables being much stronger correlates than local-scale variables, and (4) the phylogenetic structures of cold tolerance and at least one other trait

Full Text Available Household expenditure on health has increasingly remained a major source of health care financing in Nigeria despite the introduction of several social health scheme policies provided by the government for meeting the health care costs of patients. Recognizing these limitations, this study assessed the type of health care services people commonly use in various illnesses and the sociodemographic correlates of the preferred health care services by household heads in six rural communities of North Central Nigeria. A cross-sectional community-based descriptive study design was used to study 154 household heads in the settlements using a multistage sampling method. Multiple logistic regressions were performed to investigate independent predictors that had significant chi-square at P<0.05. The leading causes of illness experienced by respondents were medical conditions (42.0% and 41.7% of them sought treatment from patent medicine vendors. The dominant reasons for health-seeking preferences were financial access (53.7% and proximity (48.6%. Age had a higher impact (Beta = 0.892 on the health-seeking preferences of the respondents as compared to their occupation and religion (Beta = 0.368 and −0.746, resp.. Therefore, in order to meet the health care of patients, it is pertinent that the unmet needs of patients are properly addressed by appropriate agencies.

Full Text Available A total of 344 dogs belonging to people in resource-poor communities in North West Province, South Africa, was examined for ectoparasites, and all visible arthropods were collected from the left side of each dog. By doubling these numbers it was estimated that the dogs harboured 14 724 ixodid ticks, belonging to 6 species, 1028 fleas, belonging to 2 species, and 26 lice. Haemaphysalis leachi accounted for 420 and Rhipicephalus sanguineus for 14 226 of the ticks. Pure infestations of H. leachi were present on 14 dogs and of R. sanguineus on 172 dogs. Small numbers of Amblyomma hebraeum, R. appendiculatus, R. evertsi evertsi and R. simus were also collected. The predominance of R. sanguineus accounts for the high prevalence of canine ehrlichiosis (Ehrlichia canis within the survey region, compared to canine babesiosis (Babesia canis, which is transmitted by H. leachi, and is a much rarer disease.

Full Text Available AIM: Glaucoma is becoming an increasingly important public health problem and presents a greater public health challenge because the blindness it causes is irreversible. This study is aimed at assessing the knowledge and risk factors for glaucoma among adults in Oke-ose community, Kwara State in North-Cental Nigeria. METHODS: This is a cross-sectional study which assessed the knowledge and risk factors for glaucoma among adults in a rural community of Kwara State. The respondents were selected using cluster sampling technique. Interviewer- administered semi-structured questionnaire was used to collect data. Data was analyzed using SPSS version 15. RESULTS: Less than half 94(47.0% respondents were aware of glaucoma. Only 11(5.5% respondents had some knowledge of symptoms and 18(9.0% had knowledge of the risk factors. Socio-economic status, age of respondents and educational status and family history of glaucoma among the respondents significantly influenced the awareness and knowledge of the disease (p<0.05. Among the respondents, a total of 22(11.0% and 37(18.5% were diabetic and hypertensive respectively. Only five (2.5% of respondents had high risk perception of glaucoma. CONCLUSION: The presence of risk factors for glaucoma coupled with the poor risk perception and poor knowledge of the disease require urgent community directed eye care interventions to reduce the devastating effects of glaucoma.

The progress regarding weapons of mass destruction (WMD) programmes in North Korea and the instability on the Korean Peninsula have taken a back seat in the international community's analysis and perhaps its concerns for more than a year. The last event to provoke a wave of protest and tangible renewed interest occurred on 12 February 2013 when Pyongyang carried out its third nuclear test with an estimated yield of 6 to 8 kilo-tonnes. The United Nations Security Council condemned the test on 7 March (Resolution 2094). With the exception of several recent Security Council declarations, it is clear that activity on the part of the international community has been sparse. The same can be said with regard to the European Union and the United States. This state of affairs is not surprising. The analysis takes note of it by ceasing, there or thereabouts, to produce new material. Firstly, the North Korean crisis is a long-term one and the diplomatic process that is meant to lead to its resolution has been interrupted; the Six-Party Talks have been at a standstill since the end of 2008. A agreement between the United States and North Korea, concluded on 29 February 2012 under which the North Korean regime accepted the principle of a moratorium on long-range missile tests, nuclear tests, and all activity at the Yongbyon nuclear complex lastly barely a few days. Many actors involved in the management of this crisis are suffering from a weariness whose acknowledgement is politically incorrect: with regard to Pyongyang's launch of missiles and rockets last spring, the U.S. admiral Samuel Locklear told the Associated Press in July 'you become somewhat numb, you start to say, well, it's not so much of a big deal'. Moreover, since 2013, the focus of international security with regard to WMD and beyond has also largely shifted from North-East Asia to the Middle East and Eastern Europe. Pell-mell, the worsening and broadening of the war in Syria, the terrorist surge in Iraq, the

Little is known about Clostridium difficile infection (CDI) in Asia. The aims of our study were to explore (i) the prevalence, risk factors and molecular epidemiology of CDI and colonization in a tertiary academic hospital in North-Eastern Peninsular Malaysia; (ii) the rate of carriage of C. difficile among the elderly in the region; (iii) the awareness level of this infection among the hospital staffs and students. For stool samples collected from hospital inpatients with diarrhea (n = 76) and healthy community members (n = 138), C. difficile antigen and toxins were tested by enzyme immunoassay. Stool samples were subsequently analyzed by culture and molecular detection of toxin genes, and PCR ribotyping of isolates. To examine awareness among hospital staff and students, participants were asked to complete a self-administered questionnaire. For the hospital and community studies, the prevalence of non-toxigenic C. difficile colonization was 16% and 2%, respectively. The prevalence of CDI among hospital inpatients with diarrhea was 13%. Out of 22 C. difficile strains from hospital inpatients, the toxigenic ribotypes 043 and 017 were most common (both 14%). In univariate analysis, C. difficile colonization in hospital inpatients was significantly associated with greater duration of hospitalization and use of penicillin (both P difficile colonization is prevalent in a Malaysian hospital setting but not in the elderly community with little or no contact with hospitals. Awareness of CDI is alarmingly poor.

The community-associated methicillin-resistant Staphylococcus aureus (CA-MRSA) epidemic in the United States is attributed to the spread of the USA300 clone. An epidemic of CA-MRSA closely related to USA300 has occurred in northern South America (USA300 Latin-American variant, USA300-LV). Using phylogenomic analysis, we aimed to understand the relationships between these 2 epidemics. We sequenced the genomes of 51 MRSA clinical isolates collected between 1999 and 2012 from the United States, Colombia, Venezuela, and Ecuador. Phylogenetic analysis was used to infer the relationships and times since the divergence of the major clades. Phylogenetic analyses revealed 2 dominant clades that segregated by geographical region, had a putative common ancestor in 1975, and originated in 1989, in North America, and in 1985, in South America. Emergence of these parallel epidemics coincides with the independent acquisition of the arginine catabolic mobile element (ACME) in North American isolates and a novel copper and mercury resistance (COMER) mobile element in South American isolates. Our results reveal the existence of 2 parallel USA300 epidemics that shared a recent common ancestor. The simultaneous rapid dissemination of these 2 epidemic clades suggests the presence of shared, potentially convergent adaptations that enhance fitness and ability to spread. © The Author 2015.

Full Text Available This paper, mainly based on literature and documents from North Korea and Russia, described how health care system had been formulated during the period of between liberation from Japanese Occupation and formation of its own government in North Korea, which is so-called 'the Period of People's Democracy'.North Korea authorities, by themselves, address that their health care system is characterized by state medicine, universal free medical care, emphasis on preventive medicine, community(ho doctors in charge, provisions of modern medical services in parallel with traditional ones, imposed high value on ideologies of medical personnel, and mass participation of health programs so on, taken rise since this period.Under North Korea's socialistic regime, authorities started to restructure health care system through national health care organizations and institutes, which partially provided medical service free. Also, they emphasized preventive medicine against 'capitalistic' treatment-oriented medicine, and community(ho doctor in-charge was derived from this period.It showed that the mass participation on health program was equal hereafter and they had under bias toward more emphasis on ideology of medical personnel rather than their professionalism. The attempt to develop traditional medicine had been made during this period, however, much funding and support was not observed.In this period, it showed that a series of action to restructure health care system had been gradually carried out.

Multi-nutrient, multi-group model of present and future oceanic phytoplankton communities

2006-01-01

Full Text Available Phytoplankton community composition profoundly affects patterns of nutrient cycling and the dynamics of marine food webs; therefore predicting present and future phytoplankton community structure is crucial to understand how ocean ecosystems respond to physical forcing and nutrient limitations. We develop a mechanistic model of phytoplankton communities that includes multiple taxonomic groups (diatoms, coccolithophores and prasinophytes, nutrients (nitrate, ammonium, phosphate, silicate and iron, light, and a generalist zooplankton grazer. Each taxonomic group was parameterized based on an extensive literature survey. We test the model at two contrasting sites in the modern ocean, the North Atlantic (North Atlantic Bloom Experiment, NABE and subarctic North Pacific (ocean station Papa, OSP. The model successfully predicts general patterns of community composition and succession at both sites: In the North Atlantic, the model predicts a spring diatom bloom, followed by coccolithophore and prasinophyte blooms later in the season. In the North Pacific, the model reproduces the low chlorophyll community dominated by prasinophytes and coccolithophores, with low total biomass variability and high nutrient concentrations throughout the year. Sensitivity analysis revealed that the identity of the most sensitive parameters and the range of acceptable parameters differed between the two sites. We then use the model to predict community reorganization under different global change scenarios: a later onset and extended duration of stratification, with shallower mixed layer depths due to increased greenhouse gas concentrations; increase in deep water nitrogen; decrease in deep water phosphorus and increase or decrease in iron concentration. To estimate uncertainty in our predictions, we used a Monte Carlo sampling of the parameter space where future scenarios were run using parameter combinations that produced acceptable modern day outcomes and the

With the commitment of the national government to provide universal healthcare at cheap and affordable prices in India, public healthcare services are being strengthened in India. However, there is dearth of cost data for provision of health services through public system like primary & community health centres. In this study, we aim to bridge this gap in evidence by assessing the total annual and per capita cost of delivering the package of health services at PHC and CHC level. Secondly, we determined the per capita cost of delivering specific health services like cost per antenatal care visit, per institutional delivery, per outpatient consultation, per bed-day hospitalization etc. We undertook economic costing of fourteen public health facilities (seven PHCs and CHCs each) in three North-Indian states viz., Haryana, Himachal Pradesh and Punjab. Bottom-up costing method was adopted for collection of data on all resources spent on delivery of health services in selected health facilities. Analysis was undertaken using a health system perspective. The joint costs like human resource, capital, and equipment were apportioned as per the time value spent on a particular service. Capital costs were discounted and annualized over the estimated life of the item. Mean annual costs and unit costs were estimated along with their 95% confidence intervals using bootstrap methodology. The overall annual cost of delivering services through public sector primary and community health facilities in three states of north India were INR 8.8 million (95% CI: 7,365,630-10,294,065) and INR 26.9 million (95% CI: 22,225,159.3-32,290,099.6), respectively. Human resources accounted for more than 50% of the overall costs at both the level of PHCs and CHCs. Per capita per year costs for provision of complete package of preventive, curative and promotive services at PHC and CHC were INR 170.8 (95% CI: 131.6-208.3) and INR162.1 (95% CI: 112-219.1), respectively.

Effects of ocean acidification on primary production in a coastal North Sea phytoplankton community.

Directory of Open Access Journals (Sweden)

Tim Eberlein

Full Text Available We studied the effect of ocean acidification (OA on a coastal North Sea plankton community in a long-term mesocosm CO2-enrichment experiment (BIOACID II long-term mesocosm study. From March to July 2013, 10 mesocosms of 19 m length with a volume of 47.5 to 55.9 m3 were deployed in the Gullmar Fjord, Sweden. CO2 concentrations were enriched in five mesocosms to reach average CO2 partial pressures (pCO2 of 760 μatm. The remaining five mesocosms were used as control at ambient pCO2 of 380 μatm. Our paper is part of a PLOS collection on this long-term mesocosm experiment. Here, we here tested the effect of OA on total primary production (PPT by performing 14C-based bottle incubations for 24 h. Furthermore, photoacclimation was assessed by conducting 14C-based photosynthesis-irradiance response (P/I curves. Changes in chlorophyll a concentrations over time were reflected in the development of PPT, and showed higher phytoplankton biomass build-up under OA. We observed two subsequent phytoplankton blooms in all mesocosms, with peaks in PPT around day 33 and day 56. OA had no significant effect on PPT, except for a marginal increase during the second phytoplankton bloom when inorganic nutrients were already depleted. Maximum light use efficiencies and light saturation indices calculated from the P/I curves changed simultaneously in all mesocosms, and suggest that OA did not alter phytoplankton photoacclimation. Despite large variability in time-integrated productivity estimates among replicates, our overall results indicate that coastal phytoplankton communities can be affected by OA at certain times of the seasonal succession with potential consequences for ecosystem functioning.

This report has data on population, administration, finance, housing, health and safety, human services, education, and water and sewage for 325 energy-impacted communities. A review of current and potential energy developments in the region shows over 900 energy resource impacts listed for the 325 impacted communities. Coal development represents over one-third of the developments listed. Communities reporting coal development are distributed as follows: Colorado (36), Montana (42), North Dakota (61), South Dakota (13), Utah (73), and Wyoming (35). Energy-conversion initiatives represent another high incidence of energy-resource impact, with uranium development following closely with 83 communities reporting uranium development impact in the region. These projections indicate continued development of regional energy resources to serve national energy requirements. The 325 impacted communities as reported: Colorado (46), Montana (73), North Dakota (62), South Dakota (21), Utah (80), and Wyoming (43) follow a distribution pattern similar to that of future projects which illustrates that no area of the region will escape the impacts of energy development.

Over the last decade, studies have begun to shed light on the distribution and genetic characterization of Echinococcus multilocularis, the causative agent of alveolar echinococcosis (AE), in North America. Recent findings indicate that the parasite is likely expanding its range in the central region of the United States and Canada and that invasions of European strains might have occurred. In our review, we present the available data on E. multilocularis infections in wild and domestic animals and humans in North America and emphasize the lack of knowledge on the distribution of the parasite in wild and domestic hosts. Furthermore, we stress the need to better understand the complexity of host communities and their roles in shaping the transmission and distribution of the parasite. We hypothesize that a lack of knowledge about AE by North American physicians might result in the misdiagnosis of cases and an underestimation of disease incidence. The endemic presence of the parasite in urban areas and a recent human case in Alberta, Canada, suggest that the scientific community may need to reconsider the local public health risks, re-assess past cases that might have been overlooked and increase surveillance efforts to identify new cases of human AE.

Full Text Available Abstract Background Brachial-ankle pulse wave velocity (baPWV, which reflects the stiffness of both central and peripheral muscular arteries, has been frequently used as a simple index for assessing arterial stiffness. The aim of the present study was to investigate the prevalence of arterial stiffness in North China based on baPWV measurements, and explore the associations between increased arterial stiffness and risk factors of cardiovascular diseases (CVD. Methods Twenty-three community populations were established in North China. For each participant, parameters for calculating baPWV, including blood pressures and pressure waveforms, were measured using a non-invasive automatic device. All participants were required to respond to an interviewer-led questionnaire including medical histories and demographic data, and to receive blood tests on biochemical indictors. Results A total of 2,852 participants were finally investigated. Among them, 1,201 people with low burden of CVD risk factors were chosen to be the healthy reference sample. The cut-off point of high baPWV was defined as age-specific 90th percentile of the reference sample. Thus, the prevalence of high baPWV was found to be 22.3% and 26.4% in men and women respectively. After adjusted for age, heart rate (HR, systolic blood pressure (SBP, fasting glucose level, and smoking were significantly associated with high baPWV in men; while level of serum total cholesterol (TC, HR, SBP, and diabetes were significantly associated with high baPWV in women. Conclusions Based on the age-specific cut-off points, the middle-aged population has a higher prevalence of high baPWV in North China. There exists a difference between men and women in terms of the potential risk factors associated with arterial stiffness.

Concern has been expressed in North Carolina that solid waste facilities may be disproportionately located in poor communities and in communities of color, that this represents an environmental injustice, and that solid waste facilities negatively impact the health of host communities. Our goal in this study was to conduct a statewide analysis of the location of solid waste facilities in relation to community race and wealth. We used census block groups to obtain racial and economic characteristics, and information on solid waste facilities was abstracted from solid waste facility permit records. We used logistic regression to compute prevalence odds ratios for 2003, and Cox regression to compute hazard ratios of facilities issued permits between 1990 and 2003. The adjusted prevalence odds of a solid waste facility was 2.8 times greater in block groups with > or = 50% people of color compared with block groups with or = 100,000 dollars. Among block groups that did not have a previously permitted solid waste facility, the adjusted hazard of a new permitted facility was 2.7 times higher in block groups with > or = 50% people of color compared with block groups with waste facilities present numerous public health concerns. In North Carolina solid waste facilities are disproportionately located in communities of color and low wealth. In the absence of action to promote environmental justice, the continued need for new facilities could exacerbate this environmental injustice.

Climate is a critical driver of many fish populations, assemblages, and aquatic communities. However, direct observational studies of climate change impacts on North American inland fishes are rare. In this synthesis, we (1) summarize climate trends that may influence North American inland fish populations and assemblages, (2) compile 31 peer-reviewed studies of documented climate change effects on North American inland fish populations and assemblages, and (3) highlight four case studies representing a variety of observed responses ranging from warmwater systems in the southwestern and southeastern United States to coldwater systems along the Pacific Coast and Canadian Shield. We conclude by identifying key data gaps and research needs to inform adaptive, ecosystem-based approaches to managing North American inland fishes and fisheries in a changing climate.

To decipher the influence of depth stratification and surface provincialism on the dark ocean prokaryotic community composition, we sampled the major deep-water masses in the eastern North Atlantic covering three biogeographic provinces. Their diversity was evaluated using ordination and canonical analysis of 454 pyrotag sequences. Variance partitioning suggested that 16% of the variation in the bacterial community composition was based on depth stratification while 9% of the variation was due to geographic location. General linear mixed effect models showed that the community of the subsurface waters was connected to the dark ocean prokaryotic communities in different biogeographic provinces. Cluster analysis indicated that some prokaryotic taxa are specific to distinct regions in bathypelagic water masses. Taken together, our data suggest that the dark ocean prokaryotic community composition of the eastern North Atlantic is primed by the formation and the horizontal transport of water masses. © 2016 Society for Applied Microbiology and John Wiley & Sons Ltd.

Impact of coastal defence structures (tetrapods) on a demersal hard-bottom fish community in the southern North Sea.

Science.gov (United States)

Wehkamp, Stephanie; Fischer, Philipp

2013-02-01

In the coming decades, artificial defence structures will increase in importance worldwide for the protection of coasts against the impacts of global warming. However, the ecological effects of such structures on the natural surroundings remain unclear. We investigated the impact of experimentally introduced tetrapod fields on the demersal fish community in a hard-bottom area in the southern North Sea. The results indicated a significant decrease in fish abundance in the surrounding area caused by migration effects towards the artificial structures. Diversity (HB) and evenness (E) values exhibited greater variation after the introduction of the tetrapods. Additionally, a distinct increase in young-of-the-year (YOY) fish was observed near the structures within the second year after introduction. We suggest that the availability of adequate refuges in combination with additional food resources provided by the artificial structures has a highly species-specific attraction effect. However, these findings also demonstrate that our knowledge regarding the impact of artificial structures on temperate fish communities is still too limited to truly understand the ecological processes that are initiated by the introduction of artificial structures. Long-term investigations and additional experimental in situ work worldwide will be indispensable for a full understanding of the mechanisms by which coastal defence structures interact with the coastal environment.

Report on wind energy for small communities

Energy Technology Data Exchange (ETDEWEB)

Maissan, J.F. [Leading Edge Projects Inc., Whitehorse, YT (Canada)

2006-04-15

Wind energy projects can be economically viable in the north under a range of conditions when oil prices are in the range of $60 U.S. per barrel. Some of the requirements for economic viability include locations with economies of scale, availability of local equipment, availability of local technical human resources, access to reasonable transportation, and a committed community and project proponent. This paper presented the results of a study on wind energy in small northern communities. The objective of the paper was to provide an assessment of the feasibility of wind power to community leaders in diesel-dependant remote communities. The paper provided a review of wind power technologies including wind turbines; wind turbine towers; wind-diesel integration; wind penetration levels; anti-icing technology; suppliers of wind-diesel integration systems; and wind turbine manufacturers promoting wind-diesel systems. The paper also provided a review of the historical capital costs for the installation of wind projects; recommendations from project developers; project site selection criteria; as well as a simplified economic analyses for small communities. The paper also discussed the successful Kotzebue Alaska wind-diesel project as a model to follow. It described how to start a wind energy program with reference to the roles of the federal government, territorial governments and their power utilities. It was demonstrated that wind energy can be a cost effective option to reduce diesel generation requirements in the appropriate circumstances. It was concluded that deployment of wind energy in the north still needs to proceed on a carefully planned path beginning with leader projects and branching out from there. In addition, there is a need for good quality wind resource assessment at potential wind project locations in many communities in the north. refs., tabs., figs.

This study evaluated the long-term effects of a school- and community-based smoking prevention program in Finland. Four intervention schools from North Karelia and two control schools from another province were chosen for the evaluation. Students who received the intervention were taught to resist social pressures to smoke. The program began in 1978 with seventh-grade students and ran through 1980, with a 15-year follow-up. In North Karelia, a community-based smoking cessation program for adults was also carried out. Mean lifetime cigarette consumption was 22% lower among program subjects than among control subjects. Smoking and prevalence were lower up to the age of 21. Long-term smoking prevention effects can be achieved if a school-based program using a social influence model is combined with community and mass media interventions.

Full Text Available Background: Polycystic ovary syndrome (PCOS is one of the most common endocrine disorders in women of reproductive age. Due to the logistics of diagnosis and lack of consensus on the diagnostic criteria, there are very few prevalence studies in the community. This study was aimed to assess the prevalence of PCOS in women 18-25 years of age, conducted in college girls from Lucknow, North India. Materials and Methods: Sample size for the study was calculated as 1052. Girls from 3 different colleges were approached (n = 2150, 1520 (70.7% agreed to participate. They were asked to fill up a questionnaire asking details of menstrual cycle and features of hyperandrogenism. Hirsutism was self-reported. Responses were verified by a trained research assistant. A probable case was defined as a girl with menstrual irregularity (MI or hirsutism (H or both. All the probable cases were invited for detailed examination, hormone estimation, and ovarian ultrasonography. Results: Of the 1520 girls, 200 (13.1% were labeled as probable cases; 175 (87.5% had MI and 25 (12.5% had both MI and H. Of the 200 cases, 75 (37.5% had hormonal evaluation while 11 agreed for ultrasonography. 27 girls had confirmed PCOS. Therefore, if all the 200 girls would have had hormonal evaluation, 56 girls were likely to be confirmed as PCOS, giving a calculated prevalence of 3.7% (95% CI, 2.6-4.4 in this population. The mean age of these PCOS cases was 18.96 ± 1.73 yrs, body mass index was 21.72 ± 5.48 Kg/m 2 , and waist hip ratio was 0.81 ± 0.08. Only 12% girls had a body mass index ≥ 27.5 Kg/m 2 , but 44% had waist hip ratio > 0.81, again highlighting that despite low BMI, Indians have more abdominal obesity. Conclusion: Calculated prevalence of PCOS in women between the ages of 18-25 years from Lucknow, north India, is 3.7%. Majority of these girls were lean but have abdominal obesity.

Abstract All over the world, health behaviour is considered a complex, far reaching and powerful phenomenon. People's lives are influenced by their own or others' health behaviour on a daily basis. Whether it has to do with smoking, drinking, pollution, global warming or HIV management, it touches lives and it challenges personal and community responses. Health behaviour, and health behaviour change, probably holds the key to many a person's immediate or prolonged life or death outcomes. The same can be said about communities, culture groups and nations. This SANPAD-funded study focused on research questions relating to health behaviour change for people living with HIV (PLWH) in the North-West Province in South Africa. It investigated whether a comprehensive community-based HIV stigma reduction intervention caused health behaviour change in PLWH. An quantitative single system research design with one pre- and four repetitive post-tests utilizing purposive sampling was used to test change-over-time in the health behaviour of 18 PLWH. The results of the study indicated statistical and/or practical significant change-over-time. The intervention not only addressed the health behaviour of PLWH, but also their HIV stigma experiences, HIV signs and symptoms and their quality of life in the context of being HIV positive. The recommendations include popularization of the comprehensive community-based HIV stigma reduction intervention and extending it to include a second intervention to strengthen health behaviour and quality of life for PLWH in the community at large.

To estimate the number of new cases of cleft lip and cleft palate in the department (state) of Alta Verapaz, Guatemala, in 2012. Cross-sectional survey of midwives from communities identified through a two-stage cluster-sampling process. Midwives were asked how many babies they had delivered in the past year and how many of those newborns had various types of birth defects, as illustrated in pictures. Indigenous Mayan communities in rural north-central Guatemala. Midwives (n = 129) who had delivered babies in the previous year. Reports of babies born with cleft lip and cleft palate. A 1-year prevalence rate of 18.9 per 10,000 for cleft lip and 4.7 per 10,000 for cleft palate was estimated for Alta Verapaz. None of the cases of cleft lip also had cleft palate. The indigenous communities in north-central Guatemala might have a relatively high cleft lip prevalence rate compared with the global average.

What is the pollution status of North Sea sediments?

Chapman, P.M.; Heip, C.; Cofino, W.

1993-01-01

A March 1990 international sea-going workshop in Bremerhaven, Germany provided the opportunity to conduct detailed sediment toxicity testing in concert with studies of fish histopathology, bioaccumulation, benthic community structure, and sediment chemical contamination in the North Sea. Two gradients of sediment chemical contamination were tested, one from an abandoned oil platform and the other from the mouth of the Elbe River northward to the Dogger Bank. Using a preponderance of evidence approach, it was determined that sediments nearest the Elbe are moderately polluted (pollution is defined as contamination, toxicity, and community alteration) and that sediments offshore and at the Dogger Bank are unpolluted. Sediments nearest the oil platform showed evidence for a low level of pollution, but there was no evidence of pollution 125 m from the platform. The results suggest the testable hypothesis that North Sea sediments away from point sources of pollution such as coastal areas and drilling platforms are presently not polluted. 46 refs., 2 figs., 6 tabs

The morbidity and mortality of Latino immigrants in the United States (US) stem from a complex mix of policy, culture, discrimination and economics. Immigrants working as day labourers may be particularly vulnerable to the negative influences of these social factors due to limited access to social, financial and legal resources. We aimed to understand how the health of male Latino day labourers in North Carolina, US is influenced by their experiences interacting with their community and perceptions of their social environment. To respond to our research questions, we conducted three focus groups (n = 9, n = 10, n = 10) and a photovoice project (n = 5) with Latino male immigrants between October 2013 and March 2014. We conducted a thematic analysis of transcripts from the discussions in the focus groups and the group discussions with Photovoice participants. We found that men's health and well-being were primarily shaped by their experiences and feelings of discrimination and marginalisation. We identified three main links between discrimination/marginalisation and poor health: (i) dangerous work resulted in workplace injuries or illnesses; (ii) unsteady employment caused stress, anxiety and insufficient funds for healthcare; and (iii) exclusionary policies and treatment resulted in limited healthcare accessibility. Health promotion with Latino immigrant men in new settlement areas could benefit from community-building activities, addressing discrimination, augmenting the reach of formal healthcare and building upon the informal mechanisms that immigrants rely on to meet their health needs. Reforms to immigration and labour policies are also essential to addressing these structural barriers to health for these men. © 2016 John Wiley & Sons Ltd.

North Central Project: Environment act proposal

1992-05-01

Manitoba Hydro proposes to construct a power transmission and distribution line system to connect 12 northern Manitoba communities to the utility's central power grid. The purpose of this North Central Project (NCP) is to provide reliable and unrestricted electric service to remote communities now largely receiving limited diesel-generated power. The NCP is composed of a 138-kV transmission line running ca 350 km from the Kelsey Generating Station, ca 160 km of 25-kV distribution lines, new transformer stations at four communities, upgraded internal distribution systems within the communities, removal of existing diesel stations and restoration of the sites, modifications and additions to the Kelsey switchyard, and a communications system. The NCP is described in detail, including proposed line routes and transformer station locations, rationales for site and route selection, projected impacts on the environment and local societies, and consultations with the communities to be affected. Potential impacts are expected to be modest, with few unmitigable adverse impacts and a number of potentially significant positive benefits. Impact management measures are proposed to prevent or mitigate adverse effects and to create or enhance positive impacts such as local employment of native peoples. 49 figs., 1 tab

2007-11-15

North America is an energy community fortunate to be endowed with a rich and varied resource base. It consumes about a third of the world's energy and produces about one quarter of world energy supply. North America depends on a mix of complementary energy sources that should remain competitive but not in conflict. The current supply mix varies between Canada, the United States and Mexico, but fossil fuels are dominant across the region, leaving the three member countries vulnerable to a myriad of risks associated with traditional supply sources. Energy trade between all three countries is also a major contributor to the region's economy. Thus, the impetus for collaboration across the region has grown out of the common goals of energy security and economic prosperity. The goal of the WEC regional group was to discuss avenues for advancing North American cooperation and coordination on a range of energy issues. An additional objective was to develop policy recommendations that will facilitate effective development and use of the region's energy resources. Results and recommendtaions are summarized from three forums that focused on the pertinent issues of energy trade, energy efficiency and energy diversification. The inaugural forum (Energy Trade) was held in Washington, D.C. in the fall of 2005. The following summer, the second forum (Energy Efficiency) took place in Mexico City. The third forum (Energy Diversification) was hosted in Halifax, Nova Scotia.

Silicate:nitrate ratios of upwelled waters control the phytoplankton community sustained by mesoscale eddies in sub-tropical North Atlantic and Pacific

Directory of Open Access Journals (Sweden)

T. S. Bibby

2011-03-01

Full Text Available Mesoscale eddies in sub-tropical gyres physically perturb the water column and can introduce macronutrients to the euphotic zone, stimulating a biological response in which phytoplankton communities can become dominated by large phytoplankton. Mesoscale eddies may therefore be important in driving export in oligotrophic regions of the modern ocean. However, the character and magnitude of the biological response sustained by eddies is variable. Here we present data from mesoscale eddies in the Sargasso Sea (Atlantic and the waters off Hawai'i (Pacific, alongside mesoscale events that affected the Bermuda Atlantic Time-Series Study (BATS over the past decade. From this analysis, we suggest that the phytoplankton community structure sustained by mesoscale eddies is predetermined by the relative abundance of silicate over nitrate (Si^* in the upwelled waters. We present data that demonstrate that mode-water eddies (MWE in the Sargasso Sea upwell locally formed waters with relatively high Si^* to the euphotic zone, and that cyclonic eddies in the Sargasso Sea introduce waters with relatively low Si^*, a signature that originated in the iron-limited Southern Ocean. We propose that this phenomenon can explain the observed dominance of the phytoplankton community by large-diatom species in MWE and by small prokaryotic phytoplankton in cyclonic features. In contrast to the Atlantic, North Pacific Intermediate Water (NPIW with high Si^* may influence the cyclonic eddies in waters off Hawai'i, which also appear capable of sustaining diatom populations. These observations suggest that the structure of phytoplankton communities sustained by eddies may be related to the chemical composition of the upwelled waters in addition to the physical nature of the eddy.

Health risks from radioactive objects on beaches in the vicinity of the Sellafield site in west Cumbria

2014-07-01

A programme of monitoring carried out since 2006 has found radioactive objects on beaches near the Sellafield nuclear reprocessing site in West Cumbria. These objects comprised particles with sizes smaller than or similar to grains of sand (less than 2 mm) and contaminated pebbles and stones. Public Health England has undertaken an assessment of the health risks to people using the beaches along the Cumbrian coast from these contaminated objects. The assessment has addressed two key aspects. Firstly, estimates have been made of the likelihood that people using the beaches for various activities could come into contact with a radioactive object. Secondly, for the unlikely event that an individual does come into contact with such an object, the resulting radiation doses and associated health risks have been assessed. The ingestion of an 'alpha-rich' particle (a particle for which the content of the alpha-emitting radionuclide americium-241 exceeds the content of caesium-137) has the greatest potential to give rise to significant health risks. The intestinal absorption of a range of particles recovered from West Cumbrian beaches was quantified by means of in vivo uptake studies using laboratory rats, and the results were used to predict doses that would result from the ingestion of a single particle. The conclusion of the assessment, based on the currently available information, is that the overall health risks to beach users are very low and significantly lower than other risks that people accept when using the beaches. The highest calculated lifetime risks of radiation-induced fatal cancer are of the order of one hundred thousand times smaller than the level of risk that the UK Health and Safety Executive considers to be the upper limit for an acceptable level of risk (1 in a million) for members of the public and workers. The exposure route with the greatest potential for deterministic effects, such as localised skin ulceration, is direct irradiation of

2016-09-01

Full Text Available Abstract Background The suitability of using clinical assessment to identify patients with podoconiosis in endemic communities has previously been demonstrated. In this study, we explored the feasibility and accuracy of using Community Health Implementers (CHIs for the large scale clinical screening of the population for podoconiosis in North-west Cameroon. Methods Before a regional podoconiosis mapping, 193 CHIs and 50 health personnel selected from 6 health districts were trained in the clinical diagnosis of the disease. After training, CHIs undertook community screening for podoconiosis patients under health personnel supervision. Identified cases were later re-examined by a research team with experience in the clinical identification of podoconiosis. Results Cases were identified by CHIs with an overall positive predictive value (PPV of 48.5% [34.1–70%]. They were more accurate in detecting advanced stages of the disease compared to early stages; OR 2.07, 95% CI = 1.15–3.73, p = 0.015 for all advanced stages. Accuracy of detecting cases showed statistically significant differences among health districts (χ2 = 25.30, p = 0.0001. Conclusion Podoconiosis being a stigmatized disease, the use of CHIs who are familiar to the community appears appropriate for identifying cases through clinical diagnosis. However, to improve their effectiveness and accuracy, more training, supervision and support are required. More emphasis must be given in identifying early clinical stages and in health districts with relatively lower PPVs.

Full Text Available Being part of the Indian subcontinent both the North Eastern region of India and the Bangladesh share a long common cultural, economic and political history. One of the most critical problems of developing countries like India as well as Bangladesh is their enormous increase in human population. Contraceptive Prevalence Rate (CPR of India is 48.3 and that of Bangladesh is 53.8. As the large majority of population of both the countries belong to rural area, the family planning programmes have largely remained unsuccessful because of many factors including lack of availability of contraceptive drugs in rural markets, lack of accessibility of rural people to medical personnel as well as the lack of acceptability of synthetic drugs due to various socio-cultural and religious perceptions prevailing among many ethnic communities. These contributed to a growing interest among researchers in developing contraceptives of natural origin and at present natural herbal contraception have become one of the major focuses of modern contraceptive research. Since time immemorial herbal drugs are being practiced by various rural communities and ethnic tribes in North East India as well as in Bangladesh, and hence the acceptability of herbal contraceptives is expected to be much higher among rural folk. In different parts of North East India and Bangladesh, ethnic communities are using plant based medicinal products till today. This study aims at highlighting the contraceptive property of some plants found in North-Eastern India as well as in Bangladesh.

Secondary education among lower caste adolescent girls living in rural Karnataka, South India, is characterized by high rates of school drop-out and absenteeism. A cross-sectional baseline survey (N=2275) was conducted in 2014 as part of a cluster-randomized control trial among adolescent girls (13-14 year) and their families from marginalized communities in two districts of north Karnataka. Bivariate and multivariate logistic regression models were used. Overall, 8.7% girls reported secondary school dropout and 8.1% reported frequent absenteeism (past month). In adjusted analyses, economic factors (household poverty; girls' work-related migration), social norms and practices (child marriage; value of girls' education), and school-related factors (poor learning environment and bullying/harassment at school) were associated with an increased odds of school dropout and absenteeism. Interventions aiming to increase secondary school retention among marginalized girls may require a multi-level approach, with synergistic components that address social, structural and economic determinants of school absenteeism and dropout.

Little is known regarding how to accomplish large-scale health care improvement. Our goal is to improve the quality of chronic disease care in all primary care practices throughout North Carolina. Methods for improvement include (1) common quality measures and shared data system; (2) rapid cycle improvement principles; (3) quality-improvement consultants (QICs), or practice facilitators; (4) learning networks; and (5) alignment of incentives. We emphasized a community-based strategy and developing a statewide infrastructure. Results are reported from the first 2 years of the North Carolina Improving Performance in Practice (IPIP) project. A coalition was formed to include professional societies, North Carolina AHEC, Community Care of North Carolina, insurers, and other organizations. Wave One started with 18 practices in 2 of 9 regions of the state. Quality-improvement consultants recruited practices. Over 80 percent of practices attended all quarterly regional meetings. In 9 months, almost all diabetes measures improved, and a bundled asthma measure improved from 33 to 58 percent. Overall, the magnitude of improvement was clinically and statistically significant (P = .001). Quality improvements were maintained on review 1 year later. Wave Two has spread to 103 practices in all 9 regions of the state, with 42 additional practices beginning the enrollment process. Large-scale health care quality improvement is feasible, when broadly supported by statewide leadership and community infrastructure. Practice-collected data and lack of a control group are limitations of the study design. Future priorities include maintaining improved sustainability for practices and communities. Our long-term goal is to transform all 2000 primary-care practices in our state.

Species composition and structure of a photophilic algal community dominated by Halopteris scoparia (L. Sauvageau from the North-Western Mediterranean

Directory of Open Access Journals (Sweden)

Ballesteros, Enric

1993-12-01

Full Text Available A photophilic agal community dominated by Halopteris scoparia and other brown algae is described from sheltered environments from the North-Western Mediterranean rocky bottoms. This community is included in the Padino-Cladostephetum hirsutae previously described by FELDMANN(1937 for the same geographical area. This plant association is characterized by the lack of an upper erect stratum of Fucales and by the low degree of presence of thermophilic species which typify other similar communities described from other Mediterranean areas. Algal biomass ranges from 1100 to 2500 g dw m^-2 and coverage percentage ranges from 250 to 450 %. The great miniaturization and the extraordinary diversity and species richness of Mediterranean photophilic algal communities is assessed. Although there is not a clear seasonal change in biomass of the dominant species in the community, two structural stages can be discerned along an annual cycle: a developed community (summer and a diversified community (winter. Finally, the community structure and the environmental factors that impinge upon it are compared with those found in other Mediterranean phytobenthic communities.

Indigenous American communities face disproportionate health burdens and environmental health risks compared with the average North American population. These health impacts are issues of both environmental and reproductive justice. In this commentary, we review five indigenous communities in various stages of environmental health research and discuss the intersection of environmental health and reproductive justice issues in these communities as well as the limitations of legal recourse. The health disparities impacting life expectancy and reproductive capabilities in indigenous communities are due to a combination of social, economic, and environmental factors. The system of federal environmental and Indian law is insufficient to protect indigenous communities from environmental contamination. Many communities are interested in developing appropriate research partnerships in order to discern the full impact of environmental contamination and prevent further damage. Continued research involving collaborative partnerships among scientific researchers, community members, and health care providers is needed to determine the impacts of this contamination and to develop approaches for remediation and policy interventions.

A hierarchical community occurrence model for North Carolina stream fish

Science.gov (United States)

Midway, S.R.; Wagner, Tyler; Tracy, B.H.

2016-01-01

The southeastern USA is home to one of the richest—and most imperiled and threatened—freshwater fish assemblages in North America. For many of these rare and threatened species, conservation efforts are often limited by a lack of data. Drawing on a unique and extensive data set spanning over 20 years, we modeled occurrence probabilities of 126 stream fish species sampled throughout North Carolina, many of which occur more broadly in the southeastern USA. Specifically, we developed species-specific occurrence probabilities from hierarchical Bayesian multispecies models that were based on common land use and land cover covariates. We also used index of biotic integrity tolerance classifications as a second level in the model hierarchy; we identify this level as informative for our work, but it is flexible for future model applications. Based on the partial-pooling property of the models, we were able to generate occurrence probabilities for many imperiled and data-poor species in addition to highlighting a considerable amount of occurrence heterogeneity that supports species-specific investigations whenever possible. Our results provide critical species-level information on many threatened and imperiled species as well as information that may assist with re-evaluation of existing management strategies, such as the use of surrogate species. Finally, we highlight the use of a relatively simple hierarchical model that can easily be generalized for similar situations in which conventional models fail to provide reliable estimates for data-poor groups.

North American Regional Report

2007-11-15

North America is an energy community fortunate to be endowed with a rich and varied resource base. It consumes about a third of the world's energy and produces about one quarter of world energy supply. North America depends on a mix of complementary energy sources that should remain competitive but not in conflict. The current supply mix varies between Canada, the United States and Mexico, but fossil fuels are dominant across the region, leaving the three member countries vulnerable to a myriad of risks associated with traditional supply sources. Energy trade between all three countries is also a major contributor to the region's economy. Thus, the impetus for collaboration across the region has grown out of the common goals of energy security and economic prosperity. The goal of the WEC regional group was to discuss avenues for advancing North American cooperation and coordination on a range of energy issues. An additional objective was to develop policy recommendations that will facilitate effective development and use of the region's energy resources. Results and recommendtaions are summarized from three forums that focused on the pertinent issues of energy trade, energy efficiency and energy diversification. The inaugural forum (Energy Trade) was held in Washington, D.C. in the fall of 2005. The following summer, the second forum (Energy Efficiency) took place in Mexico City. The third forum (Energy Diversification) was hosted in Halifax, Nova Scotia.

It has been reported that three human Taenia species are distributed in Indonesia: Taenia solium, Taenia asiatica and Taenia saginata. T. asiatica is well known in North Sumatra, especially on Samosir island in Lake Toba. T. solium and T. saginata are known from Bali. T. solium is most serious public health issue in Papua (former Irian Jaya). In this report, we briefly review the present situation of these three human Taenia species mainly in Bali and North Sumatra. For community based epidemiological survey, we have adopted and applied questionnaire, microscopic observation of eggs, coproantigen tests, coproDNA tests, mitochondrial DNA analysis and morphology for isolated specimens, serology for cysticercosis and taeniasis. For detection of taeniasis cases of both T. saginata and T. asiatica, questionnaire by expert doctors is perfect to detect worm carriers. Corpoantigen test developed for detection of taeniasis of T. solium is also highly reliable to detect taeniasis carriers in the community. Epidemiological data from these two islands 2002-2005 are reviewed with backgrounds of historical culture, religions and customs.

Visibility graph network analysis of natural gas price: The case of North American market

Sun, Mei; Wang, Yaqi; Gao, Cuixia

2016-11-01

Fluctuations in prices of natural gas significantly affect global economy. Therefore, the research on the characteristics of natural gas price fluctuations, turning points and its influencing cycle on the subsequent price series is of great significance. Global natural gas trade concentrates on three regional markets: the North American market, the European market and the Asia-Pacific market, with North America having the most developed natural gas financial market. In addition, perfect legal supervision and coordinated regulations make the North American market more open and more competitive. This paper focuses on the North American natural gas market specifically. The Henry Hub natural gas spot price time series is converted to a visibility graph network which provides a new direction for macro analysis of time series, and several indicators are investigated: degree and degree distribution, the average shortest path length and community structure. The internal mechanisms underlying price fluctuations are explored through the indicators. The results show that the natural gas prices visibility graph network (NGP-VGN) is of small-world and scale-free properties simultaneously. After random rearrangement of original price time series, the degree distribution of network becomes exponential distribution, different from the original ones. This means that, the original price time series is of long-range negative correlation fractal characteristic. In addition, nodes with large degree correspond to significant geopolitical or economic events. Communities correspond to time cycles in visibility graph network. The cycles of time series and the impact scope of hubs can be found by community structure partition.

Highlights: • Microorganisms mediate processes affecting the fate and impacts of marine plastic. • North Pacific Gyre (NPG) plastics were examined with scanning-electron microscopy. • Bacillus bacteria and pennate diatoms dominated the NPG plastic fouling community. • Bacterial abundance was patchily distributed but increased on foamed polystyrene. • Diatom abundance increased on rough surfaces and at sites with high plastic density. -- Abstract: Microorganisms likely mediate processes affecting the fate and impacts of marine plastic pollution, including degradation, chemical adsorption, and colonization or ingestion by macroorganisms. We investigated the relationship between plastic-associated microorganism communities and factors such as location, temperature, salinity, plankton abundance, plastic concentration, item size, surface roughness, and polymer type. Small plastic items from the surface of the North Pacific Gyre in 2011 were examined using scanning electron microscopy. Bacillus bacteria (mean 1664 ± 247 individuals mm −2 ) and pennate diatoms (1097 ± 154 mm −2 ) were most abundant, with coccoid bacteria, centric diatoms, dinoflagellates, coccolithophores, and radiolarians present. Bacterial abundance was patchy, but increased on foamed polystyrene. Diatom abundance increased on items with rough surfaces and at sites with high plastic concentrations. Morphotype richness increased slightly on larger fragments, and a biogeographic transition occurred between pennate diatom groups. Better characterizing this community will aid in understanding how it interacts with plastic pollution

Bird community conservation and carbon offsets in western North America.

Science.gov (United States)

Schuster, Richard; Martin, Tara G; Arcese, Peter

2014-01-01

Conservation initiatives to protect and restore valued species and communities in human-dominated landscapes face huge challenges linked to the cost of acquiring habitat. We ask how the sale of forest carbon offsets could reduce land acquisition costs, and how the alternate goals of maximizing α or β-diversity in focal communities could affect the prioritization land parcels over a range of conservation targets. Maximizing total carbon storage and carbon sequestration potential reduced land acquisition costs by up to 48%. Maximizing β rather than α-diversity within forest and savannah bird communities reduced acquisition costs by up to 15%, and when these solutions included potential carbon credit revenues, acquisition cost reductions up to 32% were achieved. However, the total cost of conservation networks increased exponentially as area targets increased in all scenarios. Our results indicate that carbon credit sales have the potential to enhance conservation outcomes in human-dominated landscapes by reducing the net acquisition costs of land conservation in old and maturing forests essential for the persistence of old forest plant and animal communities. Maximizing β versus α-diversity may further reduce costs by reducing the total area required to meet conservation targets and enhancing landscape heterogeneity. Although the potential value of carbon credit sales declined as a fraction of total acquisition costs, even conservative scenarios using a carbon credit value of $12.5/T suggest reductions in acquisition cost of up to $235 M, indicating that carbon credit sales could substantially reduce the costs of conservation.

Microbial Communities in the Vertical Atmosphere: Effects of Urbanization and the Natural Environment in Four North American Ecosystems

Airborne transport of microbial communities is a key component of the global ecosystem because it serves as a mechanism for dispersing microbial life between all surface habitats on the planet. However, most of our understanding of airborne microbial distribution is derived from samples collected near the ground. Little is understood about how the vertical layers of the air may act as a habitat filter or how local terrestrial ecosystems contribute to a vast airborne microbial seedbank. Specifically, urbanization may fundamentally alter the terrestrial sources of airborne microbial biodiversity. To address this question, we conducted airborne sampling at minimally disturbed natural sites and paired urban sites in 4 different North American ecosystems: shortgrass steppe, desert scrub, eastern deciduous forest, and northern mesic forest. All natural area sites were co-located with NEON/Ameriflux tower sites collecting atmospheric data. We developed an airborne sampling platform that uses tethered helikites at 3 replicate locations within each ecosystem to launch remote-controlled sampler payloads. We designed sampler payloads to collect airborne bacteria and fungi from 150, 30 and 2 m above the ground. Payload requirements included: ability to be disinfected and remain contaminant-free during transport, remote open/close functionality, payload weight under 6 lbs and automated collection of weather data. After sampling for 6 hours at each location, we extracted DNA collected by the samplers. We also extracted DNA from soil and plant samples collected from each location, and characterized ground vegetation. We conducted bacterial 16S amplicon-based sequencing using Mi-Seq and sequence analysis using QIIME. We used ArcGIS to determine percent land use coverage. Our results demonstrate that terrestrial ecosystem type is the most important factor contributing to differences in airborne bacterial community composition, and that communities differed by ecosystem.

Korean older intimate partner violence survivors in North America: cultural considerations and practice recommendations.

Science.gov (United States)

Shim, Woochan S; Nelson-Becker, Holly

2009-01-01

While literature on elder abuse has expanded, elder abuse by intimate partners has been less investigated. Even less is known about intimate partner violence among older Koreans living in North America. This article identifies important cultural considerations for individuals helping the Korean older adult community, beginning with the definition of intimate partner violence in this community and barriers to leaving that include traditional views of the East Asian self. Current practice interventions are discussed and recommendations for future practice such as healing han, the accumulated suffering from years of abuse, are suggested. The ultimate goal of this paper is to expand awareness in order to develop the best culturally competent prevention and intervention practice for Korean older intimate partner violence survivors in North America.

Myanmar has long been a focus of the international community as a major opium poppy cultivation region. This study used remote sensing technology and ground verification to monitor opium poppy cultivation for three opium poppy growth seasons in North Myanmar. The study found that opium poppy cultivation has remained high. In 2005-6, 2006-7 and 2007-8 growing seasons the total areas monitored were 52,482 km(2), 178,274 km(2) and 236,342 km(2) and the total cultivated area of opium poppy was 8959 ha, 18,606 ha and 22,300, respectively. This was significantly less than cultivation levels reported during the 1990s. The major cultivation regions were located in Shan State, producing 88% of total poppy cultivation in North Myanmar in 2007-8. The opium poppy was mainly cultivated in the interlocking regions controlled by the local armed forces in Shan State. The field survey noted that most households in this area were poor and poppy cultivation was a main source of income. There were also differences between our figures on poppy cultivation and those reported by United Nations Office on Drugs and Crime. Our study shows that although the opium poppy cultivation in North Myanmar has reduced over recent years, it remains a major producer of opium and to which the international community needs to pay attention, especially in those areas controlled by local armed forces.

The importance of North Sea gas to European energy supply

International Nuclear Information System (INIS)

Probert, R.

1992-01-01

Natural gas can, of course, be transported over very long distances but, because of the economics of gas transmission, its impact is most often local. This has certainly been the case with North Sea gas, which has clearly contributed significantly to European energy supply and will continue to do so for some time to come. The historical importance of the discovery of gas in the North Sea has been that it has enabled natural gas industries to grow rapidly in North West Europe. Without North Sea gas and Dutch gas it is difficult to see how town gas would have been replaced in North West Europe. Certainly, a much smaller natural gas industry would have emerged. North Sea gas has inevitably had the greatest impact on gas markets in the countries of the European Community and this will remain the case in future. Nevertheless, it is inevitable that gas will, in future, flow across more national boundaries than in the past, and that North Sea gas will have an important part to play in meeting the Central European demand for competitively priced, secure supplies. This paper discusses the United Kingdom market for gas and future demand both in the United Kingdom and more widely in Europe. An examination of the availability of gas supplies from the North Sea suggests that it is unlikely that there will be a surplus of gas for export from the United Kingdom continental shelf. Norway will remain the main source of exports, with the Netherlands also in a strong position. Transportation and political aspects are also considered. (author)

Finance and North Sea oil: the challenge of non-recourse finance

Energy Technology Data Exchange (ETDEWEB)

White, N A

1976-04-01

Many companies operating in the North Sea feel that the financial community is not responding to the complexity of their situation brought about by the interplay between national legislation and fiscal measures, technological development, extreme weather conditions, OPEC decisions, or falling oil demand. The financial community feels it is lending its depositors' money and the kind of innovations required by some companies in the oil industry would reduce its level of security. After reviewing the possible solutions, the author concludes that it is highly unlikely that non-resource finance in large amounts will be available without collateral, or other security, from outside the North Sea area. The author offers his suggestion and preference for a new kind of vehicle to be designed by the financial institutions that would provide the necessary guarantees to the lending consortium in accordance with the needs of the individual participant in the license or field project.

Papers of the Canadian Institute's 8. annual North American pipelines and storage conference : update on critical infrastructure developments and market dynamics shaping the North American grid

International Nuclear Information System (INIS)

2003-01-01

Leaders and experts from the petroleum and natural gas industry outlined some of the recent changes that have taken place in the North America gas and electricity industry. The relationship between pipeline and storage capacity was discussed with reference to how the connection affects prices at North American storage hubs. The topics of discussion ranged from the challenges associated with declines in capacity and market dynamics, to how gas marketability will be affected by the slowdown in pipeline development in North America. The investment community offered advice on long-run value creation in natural gas. The current state of development of Arctic gas was highlighted along with a review of how growth in liquefied natural gas (LNG) is changing the role of gas infrastructure in North America. It was noted that although markets will work to balance supply and demand, there is a need for new sources of North American supply to meet growing long-term demand. The fall-off in U.S. domestic natural gas supplies combined with low storage levels has created a supply crisis. The conference featured 19 presentations, of which 4 have been indexed separately for inclusion in this database. refs., tabs., figs

The Atmospheric Response to a Future Warming Deficit in North Atlantic SSTs

Science.gov (United States)

Gervais, M.; Shaman, J. L.; Kushnir, Y.

2017-12-01

As SSTs increase globally over the 21st century, global climate models project a significant deficit in warming within the subpolar gyre of the North Atlantic Ocean. This study investigates the impact of this warming deficit on atmosphere circulation. A series of large ensemble experiments are conducted using the Community Atmosphere Model 5 forced with specified sea ice and SSTs for the early (2010-2019), mid (2050-2059), and late (2090-2099) 21stcentury. SST and sea ice fields from the Community Earth System Model Large Ensemble experiment are used as boundary conditions for the control simulations. Experiments with either a filled or deepened warming hole are conducted by adding a SST perturbation field to these time-varying SST boundary conditions. Results from these experiments demonstrate that the warming hole has significant local and remote impacts on the atmosphere. Filling (deepening) the warming hole results in a local increase (decrease) in turbulent heat fluxes relative to the control run and consequentially an increase (decrease) in temperature in the overlying lower troposphere that spreads over Europe. There are significant impacts on the location and strength of both the North Atlantic and North Pacific jets as well as on the North Atlantic Oscillation. These impacts of the warming hole on both the mean state and variability of the atmosphere have important implications for sensible weather in the Northern Hemisphere and in particular over Europe.

The data are primarily from mesic, hilly and mountainous sites ranging from the westernmost tip of the Alaska Peninsula to the northern Kenai Peninsula, spanning 1,000 km on an E–W gradient and 700 km on a N–S gradient. 127 relevés from 18 sites represent the range of structural and compositional variation in the matrix of vegetation and landform diversity. Data were analyzed by multivariate and traditional Braun-Blanquet methods. One association is distinguished, Sambuco racemosi-Alnetum viridis ass. nov. with three new subassociations, oplopanacetosum horridi, typicum, and rubetosum spectabilis with the latter subdivided into four variants. These phytocoena are well-differentiated, although they form a syntaxonomical continuum. The composition and structure of these communities are described and interpreted in relation to complex environmental factors; these are analyzed using Jancey's ranking on F-values. Community composition is primarily related to elevation, longitude, soil moisture, and latitude. Phytogeographic comparison of southwestern Alaska alder communities with those elsewhere in the North Pacific suggests a close floristic relationship to those of southcentral, southeastern Alaska and coastal British Columbia, Canada. All these communities belong to the same association, while those of the eastern and southern parts of the Kamchatka Peninsula, Russia belong to a different association. Syntaxonomy of the 4 major communities is discussed. Within the Northern Hemisphere, vascular plant species of southwestern Alaska alder thickets primarily occur in East Asia and North America, 36 %; while 26 % are circumpolar, and 22 % are restricted to North America. From a latitudinal perspective, the distribution of vascular plant species within these alder thickets peaks in the high-subarctic, low-subarctic, and temperate latitudinal zones, with low

Atmospheric warming may influence plant productivity and diversity and induce poleward migration of species, altering communities across latitudes. Complicating the picture is that communities from different continents deviate in evolutionary histories, which may modify responses to warming and migration. We used experimental wetland plant communities grown from seed banks as model systems to determine whether effects of warming on biomass production and species richness are consistent across continents, latitudes, and migration scenarios. We collected soil samples from each of three tidal freshwater marshes in estuaries at three latitudes (north, middle, south) on the Atlantic coasts of Europe and North America. In one experiment, we exposed soil seed bank communities from each latitude and continent to ambient and elevated (+2.8 °C) temperatures in the greenhouse. In a second experiment, soil samples were mixed either within each estuary (limited migration) or among estuaries from different latitudes in each continent (complete migration). Seed bank communities of these migration scenarios were also exposed to ambient and elevated temperatures and contrasted with a no-migration treatment. In the first experiment, warming overall increased biomass (+16%) and decreased species richness (-14%) across latitudes in Europe and North America. Species richness and evenness of south-latitude communities were less affected by warming than those of middle and north latitudes. In the second experiment, warming also stimulated biomass and lowered species richness. In addition, complete migration led to increased species richness (+60% in North America, + 100% in Europe), but this higher diversity did not translate into increased biomass. Species responded idiosyncratically to warming, but Lythrum salicaria and Bidens sp. increased significantly in response to warming in both continents. These results reveal for the first time consistent impacts of warming on biomass and

The overall objective of this study was to improve the representation of regional ocean circulation in the North Pacific by using high resolution atmospheric forcing that accurately represents mesoscale processes in ocean-atmosphere regional (North Pacific) model configuration. The goal was to assess the importance of accurate representation of mesoscale processes in the atmosphere and the ocean on large scale circulation. This is an important question, as mesoscale processes in the atmosphere which are resolved by the high resolution mesoscale atmospheric models such as Weather Research and Forecasting (WRF), are absent in commonly used atmospheric forcing such as CORE forcing, employed in e.g. the Community Climate System Model (CCSM).

Among the many effects of the accident at Three Mile Island are impacts upon other communities that currently host nuclear-power reactors. Because studies on communities' reactions not immediately available, this chapter reviews existing studies and speculates about possible effects. The patterns and variations in impacts on and responses of nuclear host communities have been the subject of studies at Oak Ridge National Laboratory (Oak Ridge, Tennessee) since 1972. This essay presents results from four post-licensing studies of host communities - Plymouth, Massachusetts, and Waterford, Connecticut (PL-1), and Brunswick, North Carolina, and Appling-Toombs counties, Georgia (PL-2) - along with case study and attitude survey information from two additional communities in which reactors are under construction: Hartsville, Tennessee, and Cherokee County, South Carolina. Differences and similarities between the sites have been assessed in terms of differences in input and social structure; factors affecting the generally favorable attitudes toward local nuclear plants are discussed

Anaerobic methane oxidation (AMO) is considered to be an important sink of CH4 in habitats as marine sediments. But, few studies focused on AMO in landfills which may be an important sink of CH4 derived from waste fermentation. To show evidence of AMO and to uncover function anaerobic methanotroph (ANME) community in landfill, different age waste samples were collected in Jinqianpu landfill located in north China. Through high-throughput sequencing, Methanomicrobiales and Methanosarcinales archaea associated with ANME and reverse methanogenic archaea of Methanosarcina and Methanobacterium were detected. Sulfate-reducing bacteria (SRB) (Desulfobulbus and Desulfococcus) which could couple with ANME-conducting AMO were also found. But, the community structure of ANME had no significant difference with depths. From the results of investigation, we can come to a conclusion that sulfate-dependent anaerobic methane oxidation (SR-DAMO) would be the dominant AMO process in the landfill, while iron-dependent anaerobic methane oxidation (M/IR-DAMO) process was weak though concentration of ferric iron was large in the landfill. Denitrification-dependent anaerobic methane oxidation (NR-DAMO) was negative because of lack of nitrate and relevant function microorganisms in the landfill. Results also indicate that CH4 mitigation would have higher potential by increasing electron acceptor contents and promoting the growth of relevant function microorganisms.

PAGES-Powell North America 2k database

Science.gov (United States)

McKay, N.

2014-12-01

Syntheses of paleoclimate data in North America are essential for understanding long-term spatiotemporal variability in climate and for properly assessing risk on decadal and longer timescales. Existing reconstructions of the past 2,000 years rely almost exclusively on tree-ring records, which can underestimate low-frequency variability and rarely extend beyond the last millennium. Meanwhile, many records from the full spectrum of paleoclimate archives are available and hold the potential of enhancing our understanding of past climate across North America over the past 2000 years. The second phase of the Past Global Changes (PAGES) North America 2k project began in 2014, with a primary goal of assembling these disparate paleoclimate records into a unified database. This effort is currently supported by the USGS Powell Center together with PAGES. Its success requires grassroots support from the community of researchers developing and interpreting paleoclimatic evidence relevant to the past 2000 years. Most likely, fewer than half of the published records appropriate for this database are publicly archived, and far fewer include the data needed to quantify geochronologic uncertainty, or to concisely describe how best to interpret the data in context of a large-scale paleoclimatic synthesis. The current version of the database includes records that (1) have been published in a peer-reviewed journal (including evidence of the record's relationship to climate), (2) cover a substantial portion of the past 2000 yr (>300 yr for annual records, >500 yr for lower frequency records) at relatively high resolution (<50 yr/observation), and (3) have reasonably small and quantifiable age uncertainty. Presently, the database includes records from boreholes, ice cores, lake and marine sediments, speleothems, and tree rings. This poster presentation will display the site locations and basic metadata of the records currently in the database. We invite anyone with interest in

Submerged macrophytes play a key role in north temperate shallow lakes by stabilizing clear-water conditions. Eutrophication has resulted in macrophyte loss and shifts to turbid conditions in many lakes. Considerable efforts have been devoted to shallow lake restoration in many countries, but long-term success depends on a stable recovery of submerged macrophytes. However, recovery patterns vary widely and remain to be fully understood. We hypothesize that reduced external nutrient loading leads to an intermediate recovery state with clear spring and turbid summer conditions similar to the pattern described for eutrophication. In contrast, lake internal restoration measures can result in transient clear-water conditions both in spring and summer and reversals to turbid conditions. Furthermore, we hypothesize that these contrasting restoration measures result in different macrophyte species composition, with added implications for seasonal dynamics due to differences in plant traits. To test these hypotheses, we analyzed data on water quality and submerged macrophytes from 49 north temperate shallow lakes that were in a turbid state and subjected to restoration measures. To study the dynamics of macrophytes during nutrient load reduction, we adapted the ecosystem model PCLake. Our survey and model simulations revealed the existence of an intermediate recovery state upon reduced external nutrient loading, characterized by spring clear-water phases and turbid summers, whereas internal lake restoration measures often resulted in clear-water conditions in spring and summer with returns to turbid conditions after some years. External and internal lake restoration measures resulted in different macrophyte communities. The intermediate recovery state following reduced nutrient loading is characterized by a few macrophyte species (mainly pondweeds) that can resist wave action allowing survival in shallow areas, germinate early in spring, have energy-rich vegetative

Adaptation in South Korean Society of North Korean Elite Defectors

Directory of Open Access Journals (Sweden)

Levi Nicolas

2017-10-01

Full Text Available This paper aims to explain the adaptation of North Korean elite defectors who fled from North Korea. Data used for the purpose of this article came from surveys of North Korean defectors conducted in the late 2000’s. Findings of the realized research indicate that the majority of senior defectors are experiencing less psychological and material issues when adjusting to society than regular North Korean defectors. The paper will proceed in three steps: explaining the notion of defectors, outlining their background, and focusing on their adaptation in South. Although defectors as a whole has emerged as of the most research group as a minority in South Korea, the so-called senior defectors have hardly been spotlighted. Basically North Korean senior defectors are supposed to strengthen the anti-Kim movement and legitimize the power of the South Korean government and the image of South Korea abroad. What has to be enlightened upon is the fact that North Korean senior defectors partially disagree with the integration policy of South Korean authorities. A major research question emerges: How are the experience of elite defectors localized in South Korea? How do their specific identities impact their opinion within the South Korean society? The aim of the article is also to categorize senior defectors and to provide in a single document a list of senior North Korea defectors based abroad. This kind of information is only available for Korean speaking readers. I wanted to make it accessible to the Englishspeaking community.

Status of wind energy in Nordic communities in Quebec

Energy Technology Data Exchange (ETDEWEB)

Chaumel, J.L. [Quebec Univ., Rimouski, PQ (Canada). Wind Energy Group

2003-07-01

Remote and nordic communities in Quebec include Inuit villages, the Lower North Coast, Anticosti Island, Magdalen Islands, and the James Bay region. Annual wind speed in each of these communities is more than 8.5 m/s which is ideal for wind power generation. However, wind energy projects that were underway have been abandoned for a variety of reasons. Hydro-Quebec has decided to invest in power lines to link villages in the Lower North coast. The electric utility is not interested in wind energy for the Magdalen Islands because of an existing large diesel power station. Likewise, Anticosti Island has a completely automated small diesel plant. Nordic Innu Villages are making money with fuel sales to Hydro-Quebec and have no economic interest in wind energy. Other barriers to development include a lack of government support and lack of interest in small wind projects. In addition, turbine manufacturers have not lobbied for wind energy development in Quebec's nordic communities. However, the potential exists for future development as innovations are rendering wind power more adaptable to community needs. Off-grid technology is also available. 2 figs.

Harper, Gary W; Schneider, Margaret

2003-06-01

Lesbian, gay, bisexual, and transgendered (LGBT) people continue to experience various forms of oppression and discrimination in North America and throughout the world, despite the social, legal, and political advances that have been launched in an attempt to grant LGBT people basic human rights. Even though LGBT people and communities have been actively engaged in community organizing and social action efforts since the early twentieth century, research on LGBT issues has been, for the most part, conspicuously absent within the very field of psychology that is explicitly focused on community research and action--Community Psychology. The psychological and social impact of oppression, rejection, discrimination, harassment, and violence on LGBT people is reviewed, and recent advances in the areas of LGBT health, public policy, and research are detailed. Recent advances within the field of Community Psychology with regard to LGBT research and action are highlighted, and a call to action is offered to integrate the knowledge and skills within LGBT communities with Community Psychology's models of intervention, prevention, and social change in order to build better theory and intervention for LGBT people and communities.

Full Text Available Abstract Background Throughout Brazil a large number of people seek out reptiles for their meat, leather, ornamental value and supposed medicinal importance. However, there is a dearth of information on the use of reptiles in folk medicine. In North Brazil, the freshwater turtle, Podocnemis expansa, is one of the most frequently used species in traditional medicines. Many products derived from P. expansa are utilized in rural areas and also commercialized in outdoor markets as a cure or treatment for different diseases. Here we document the use and commercialization of P. expansa for medicinal purposes in the state of Pará, Northern Brazil. Methods Data were gathered through interview-questionnaires, with some questions left open-ended. Information was collected in two localities in Pará State, North of Brazil. In the City of Belém, data was collected through interviews with 23 herbs or root sellers (13 men and 10 women. Attempts were made to interview all animal merchants in the markets visited.

The effects of regional economic integration in Europe of the pattern north-north and north-south

Directory of Open Access Journals (Sweden)

Antevski Miroslav

2007-01-01

Full Text Available This paper examines the effects of regional economic integration in Europe, especially the North-North and North-South integration patterns, and how the benefits and costs of integration are divided between countries. Outcomes depend on: comparative advantages, factor endowments, factor intensities, competitive advantages, FDI flows, transfers of technology, knowledge spillovers, economies of scale, transport costs, industry/GDP ratios, and agglomeration forces. The North-North integration between high income countries tends to lead to convergence of country incomes. Contrary, the South-South integration between low income countries causes divergence. Low income countries are likely to be better served by the North-South integration.

Implications of a North Korean Nuclear Weapons Program

Energy Technology Data Exchange (ETDEWEB)

Lehman, R.F. II

1993-07-01

The Democratic People`s Republic of Korea (DPRK) is one of the Cold War`s last remaining totalitarian regimes. Rarely has any society been as closed to outside influences and so distant from political, economic, and military developments around the globe. In 1991 and in 1992, however, this dictatorship took a number of political steps which increased Pyongyang`s interaction with the outside world. Although North Korea`s style of engagement with the broader international community involved frequent pauses and numerous steps backward, many observers believed that North Korea was finally moving to end its isolated, outlaw status. As the end of 1992 approached, however, delay and obstruction by Pyongyang became intense as accumulating evidence suggested that the DPRK, in violation of the nuclear Non-Proliferation Treaty (NPT), was seeking to develop nuclear weapons. On March 12, 1993, North Korea announced that it would not accept additional inspections proposed by the International Atomic Energy Agency (IAEA) to resolve concerns about possible violations and instead would withdraw from the Treaty. Pyongyang`s action raised the specter that, instead of a last act of the Cold War, North Korea`s diplomatic maneuvering would unravel the international norms that were to be the basis of stability and peace in the post-Cold War era. Indeed, the discovery that North Korea was approaching the capability to produce nuclear weapons suggested that the nuclear threat, which had been successfully managed throughout the Cold War era, could increase in the post-Cold War era.

The northeastern North Carolina coastal system, from False Cape, Virginia, to Cape Lookout, North Carolina, has been studied by a cooperative research program that mapped the Quaternary geologic framework of the estuaries, barrier islands, and inner continental shelf. This information provides a basis to understand the linkage between geologic framework, physical processes, and coastal evolution at time scales from storm events to millennia. The study area attracts significant tourism to its parks and beaches, contains a number of coastal communities, and supports a local fishing industry, all of which are impacted by coastal change. Knowledge derived from this research program can be used to mitigate hazards and facilitate effective management of this dynamic coastal system.

A novel marine nitrite-oxidizing Nitrospira species from Dutch coastal North Sea water

Directory of Open Access Journals (Sweden)

Suzanne Caroline Marianne Haaijer

2013-03-01

Full Text Available Marine microorganisms are important for the global nitrogen cycle, but marine nitrifiers, especially aerobic nitrite-oxidizers, remain largely unexplored. To increase the number of cultured representatives of marine nitrite-oxidizing bacteria (NOB, a bioreactor cultivation approach was adopted to first enrich nitrifiers and ultimately nitrite oxidizers from Dutch coastal North Sea water. With solely ammonia as the substrate an active nitrifiying community consisting of novel marine Nitrosomonas aerobic ammonia oxidizers (AOB and Nitrospina and Nitrospira NOB was obtained which converted a maximum of 2 mmoles of ammonia per liter per day. Switching the feed of the culture to nitrite as a sole substrate resulted in a Nitrospira NOB dominated community (approximately 80% of the total microbial community based on FISH and metagenomic data converting a maximum of 3 mmoles of nitrite per liter per day. Phylogenetic analyses based on the 16S rRNA gene indicated that the Nitrospira enriched from the North Sea is a novel Nitrospira species with Nitrospira marina as the next taxonomically described relative (94% 16S rRNA sequence identity. Transmission electron microscopy analysis revealed a cell plan typical for Nitrospira species. The cytoplasm contained electron light particles that might represent glycogen storage. A large periplasmic space was present which was filled with electron dense particles. Nitrospira-targeted PCR analyses demonstrated the presence of the enriched Nitrospira species in a time series of North Sea genomic DNA samples. The availability of this new Nitrospira species enrichment culture facilitates further in-depth studies such as determination of physiological constraints, and comparison to other NOB species.

Chevalier, S; Dedobbeleer, N; Tremblay, M

1995-01-01

Although many methods of measuring leadership have been developed in sociological studies, there are few articles on the feasibility of these methods. The goal of this study was to verify the feasibility of the "modified positional-reputational approach" developed by Nix. The study was conducted in a small community located north of Montreal. Nix's questionnaire was translated, adapted and administered to 49 key informants. Two hundred and fourteen leaders were selected. Three types of leaders were identified: the legitimizers, the effectors and the activists. Through a sociometric analysis, we established links between the different leaders and we described the power structure of the community.

The Lancashire and Cumbria Innovation Alliance (LCIA) Test Bed is a partnership between the National Health Service in England, industry (led by Philips) and Lancaster University. Through the implementation of a combination of innovative health technologies and practices, it aims to determine the most effective and cost-effective ways of supporting frail older people with long-term conditions to remain well in the community. Among the Test Bed's objectives are to improve patient activation and the ability of older people to self-care at home, reduce healthcare system utilisation, and deliver increased workforce productivity. Patients aged 55 years and over are recruited to four cohorts defined by their risk of hospital admission, with long-term conditions including chronic obstructive pulmonary disease, dementia, diabetes and heart failure. The programme is determined on an individual basis, with a range of technologies available. The evaluation is adopting a two-phase approach: phase 1 includes a bespoke patient survey and a mass matched control analysis; and phase 2 is using observational interviews with patients, and weekly diaries, action learning meetings and focus groups with members of staff and other key stakeholders. Phase 1 data analysis consists of a statistical evaluation of the effectiveness of the programme. A health economic analysis of its costs and associated cost changes will be undertaken. Phase 2 data will be analysed thematically with the aid of Atlas.ti qualitative software. The evaluation is located within a logic model framework, to consider the processes, management and participation that may have implications for the Test Bed's success. The LCIA Test Bed evaluation has received ethical approval from the Health Research Authority and Lancaster University's Faculty of Health and Medicine Research Ethics Committee. A range of dissemination methods are adopted, including deliberative panels to validate findings and develop outcomes for policy

Lindgren funnel traps baited with aggregation pheromones are widely used to monitor and manage populations of economically important bark beetles (Coleoptera: Scolytidae). This study was designed to advance our understanding of how funnel trap catches assess bark beetle communities and relative abundance of individual species. In the second year (2005) of a 3-yr study of the bark beetle community structure in north-central Arizona pine (Pinus spp.) forests, we collected data on stand structure, site conditions, and local bark beetle-induced tree mortality at each trap site. We also collected samples of bark from infested (brood) trees near trap sites to identify and determine the population density of bark beetles that were attacking ponderosa pine, Pinus ponderosa Douglas ex Lawson, in the area surrounding the traps. Multiple regression models indicated that the number of Dendroctonus and Ips beetles captured in 2005 was inversely related to elevation of the trap site, and positively associated with the amount of ponderosa pine in the stand surrounding the site. Traps located closer to brood trees also captured more beetles. The relationship between trap catches and host tree mortality was weak and inconsistent in forest stands surrounding the funnel traps, suggesting that trap catches do not provide a good estimate of local beetle-induced tree mortality. However, pheromone-baited funnel trap data and data from gallery identification in bark samples produced statistically similar relative abundance profiles for the five species of bark beetles that we examined, indicating that funnel trap data provided a good assessment of species presence and relative abundance.

Comparative metagenomic analysis of the microbial communities in the surroundings of Iheya north and Iheya ridge hydrothermal fields reveals insights into the survival strategy of microorganisms in deep-sea environments

Wang, Hai-liang; Sun, Li

2018-04-01

In this study, metagenomic analysis was performed to investigate the taxonomic compositions and metabolic profiles of the microbial communities inhabiting the sediments in the surroundings of Iheya North and Iheya Ridge hydrothermal fields. The microbial communities in four different samples were found to be dominated by bacteria and, to a much lesser extent, archaea belonging to the phyla Proteobacteria, Actinobacteria, Planctomycetes, Firmicutes, Deinococcus-Thermus, and Nitrospirae, which play important roles in the cycling of carbon, nitrogen, and sulfur. All four microbial communities (i) contained chemoautotrophs and heterotrophs, the former probably fixed CO2 via various carbon fixation pathways, and the latter may degrade organic matters using nitrate and sulfate as electron acceptors, (ii) exhibited an abundance of DNA repair genes and bacterial sulfur oxidation mediated by reverse sulfate reduction, and (iii) harbored bacteria and archaea involved in anaerobic methane oxidation via intra-aerobic denitrification and reverse methanogenesis, which were found for the first time in hydrothermal areas. Furthermore, genes involved in DNA repair, reductive acetyl-CoA pathway, and ammonia metabolism were possibly affected by distance to the vent fields. These findings facilitate our understanding of the strategies of the microbial communities to adapt to the environments in deep sea areas associated with hydrothermal vents.

Balanced Fertilization Decreases Environmental Filtering on Soil Bacterial Community Assemblage in North China

Directory of Open Access Journals (Sweden)

Youzhi Feng

2017-12-01

Full Text Available Although increasing evidences have emerged for responses of soil microorganisms to fertilizations, the knowledge regarding community assemblages that cause variations in composition is still lacking, as well as the possible feedback to soil fertility. Phylogenetic conservatism of species indicates their similar environmental preferences and/or function traits and phylogenetic signals further can infer community assemblages and influenced ecological processes. Here, we calculated the mean pairwise phylogenetic distance and nearest relative index, characterizing phylogenetic signal and the undergone ecological process to evaluate the community assembly of soil bacterial phylotypes in 20-year fertilized soils. The bacterial community assembly is structured by environmental filtering, regardless of fertilization regime. Soil phosphorous (P availability imposes selection on community assemblage and influences their community turnover among fertilizations. When P nutrient lacks, the effect of environmental filtering becomes stronger, hence bacterial functional traits become more coherent; this process results into increased intraspecific interactions characterized by co-occurrence network analysis. In contrast, when P nutrient becomes abundant, the environmental selection is mitigated; function traits are evened. This process reduces intraspecific interactions and increases carbon sequestration efficiency, which is finally of great favor to the increases in soil fertility. This study has made the first attempt, at the bacterial level, to understand how fertilization affects agroecosystems. When more phylogenetic information on how nutrient cycling-related microbes respond to fertilization becomes available, the systematic knowledge will eventually provide guidance to optimal fertilization strategies.

Epidemiology of MRSA: the North/South study of MRSA in Ireland 1999.

McDonald, P

2003-06-01

The North\\/South Study of methicillin-resistant Staphylococcus aureus (MRSA) in Ireland, 1999, includes a joint review of the epidemiology of MRSA across both jurisdictions on the island of Ireland. Data were gathered on all MRSA cases identified in laboratories in Northern Ireland (the North) and in the Republic of Ireland (the South) over a two-week period. The prevalence rate per 100000 population was 11.4 in the North and 14.0 in the South, with a marked variation across geographical regions. MRSA cases were located throughout hospitals and the community, were slightly more common in males than females, and occurred in all age groups, especially in the elderly. The majority of cases were inpatients in acute hospitals and were distributed across all types of wards. Most cases were colonized with MRSA but 5% of cases in the North and 10% in the South had invasive infection. Invasive infection was associated with intravascular lines and invasive procedures\\/surgery. Continuous surveillance is recommended to monitor the epidemiology of MRSA and the effectiveness of control measures.

Interannual variability of western North Pacific SST anomalies and its impact on North Pacific and North America

Park, Jae-Heung; An, Soon-Il; Kug, Jong-Seong

2017-12-01

In this study, the interannual variability of sea surface temperature (SST) and its atmospheric teleconnection over the western North Pacific (WNP) toward the North Pacific/North America during boreal winter are investigated. First, we defined the WNP mode as the first empirical orthogonal function (EOF) mode of SST anomalies over the WNP region (100-165°E, 0-35°N), of which the principle component time-series are significantly correlated with several well-known climate modes such as the warm pool mode which is the second EOF mode of the tropical to North Pacific SST anomalies, North Pacific oscillation (NPO), North Pacific gyre oscillation (NPGO), and central Pacific (CP)-El Niño at 95% confidence level, but not correlated with the eastern Pacific (EP)-El Niño. The warm phase of the WNP mode (sea surface warming) is initiated by anomalous southerly winds through reduction of wind speed with the background of northerly mean winds over the WNP during boreal winter, i.e., reduced evaporative cooling. Meanwhile, the atmospheric response to the SST warming pattern and its diabatic heating further enhance the southerly wind anomaly, referred to the wind-evaporation-SST (WES) feedback. Thus, the WNP mode is developed and maintained through winter until spring, when the northerly mean wind disappears. Furthermore, it is also known that anomalous upper-level divergence associated with WNP mode leads to the NPO-like structure over the North Pacific and the east-west pressure contrast pattern over the North America through Rossby wave propagation, impacting the climate over the North Pacific and North America.

Full Text Available In North Africa seasonal streams called wadi are an unique habitats with serve hydrological and thermal regime. Non-biting midges take an important part of freshwater biodiversity in North Africa. We present new data on the distribution and diversity of Chironomidae in North Tunisia. Larvae, pupal exuviae and adult males of chironomids were collected from a various freshwater ecosystems from May 2005 till April 2006. The aim of this study was to recognize the pattern of midge diversity in North Tunisia to estimate ecological value of running waters in the region. In total, 79 taxa were identified. Nearly all of the taxa were typical representatives of the Palaearctic and Mediterranean complexes. The majority of the investigated sites belonged to the protected areas in North Tunisia, such as the Ichkeul National Park, the Kroumerie Mountains and the El Feija National Park, part of the Intercontinental Reserve of the Mediterranean Biosphere. Altitudinal zonation of the communities composition was found in the lowland (250 m a.s.l. with maximum of 760 m. Whereas among the data 39 species are recorded from Tunisia for the first time, the species richness of Chironomidae is higher than previously estimated.

Mangrove forests in North Sumatera, Indonesia existed in the east coast of Sumatera Island and commonly found in Serdang Bedagai, Deli Serdang, Batubara, Tanjung Balai, Asahan, Labuhanbatu until Langkat. The effect of rehabilitated mangrove on socio-cultural of Pulau Sembilan society, Langkat, North Sumatra, Indonesia was studied. The rehabilitation was carried on May 2015 using indirect planting of 2,100 Rhizophora apiculata seedlings. Two times of observations, May and August 2015 were made to monitor and evaluate 400 rehabilitated seedlings. Sixty of 600 households were surveyed using Slovin formula to obtain community perspective on the socio-cultural impact of mangrove rehabilitation. Results showed that the growth of R. apiculata seedlings were 73.3% during four months observations. The restoration affected 65, 58.3 and 35 % of economic, social, and cultural of Pulau Sembilan society, respectively. The perspective of community on the land-use change led to 66.7% was disagreed that mangroves to be converted, 60% respondents stated that mangrove condition was degraded even worse than previously existed. Therefore, to resolve the degraded mangrove, community perspective on rehabilitation was needed (85.5%) and actively involved (88.3%). The present results suggested that the high recommendation for a rehabilitation program for the degraded area was by integrating the stake holders (government, university, and non-governmental organization) and local communities count on the mangrove ecosystems.

Canada has many isolated communities that are not connected to the electrical grid. Most of these communities meet their electricity demand through stand-alone diesel generators. Diesel generators have economic and environmental concerns that can be minimized by using hybrid renewable energy technologies. This study aims to assess the implementation of a hybrid energy system for an off-grid community in Canada and to propose the best hybrid energy combination to reliably satisfy electricity demand. Seven scenarios were developed: 1) 100% renewable resources, 2) 80% renewable resources, 3) 65% renewable resources, 4) 50% renewable resources, 5) 35% renewable resources, 6) 21% renewable resources, and 7) battery-diesel generators (0% renewable resources). A case study for the remote community of Sandy Lake, Ontario, was conducted. Hybrid systems were chosen to meet the requirements of a 4.4 MWh/day primary load with a 772 kW peak load. Sensitivity analyses were carried out to assess the impact of solar radiation, wind speed, diesel price, CO 2 penalty cost, and project interest rate on optimum results. A GHG (greenhouse gas) abatement cost was assessed for each scenario. Considering GHG emission penalty cost, the costs of electricity for the seven scenarios are $1.48/kWh, $0.62/kWh, $0.54/kWh, $0.42/kWh, $0.39/kWh, $0.37/kWh, and $0.36/kWh. - Highlights: • Modeling of hybrid renewable energy systems for an off-grid community. • Seven scenarios were developed based on various renewable energy fractions. • Cost of electricity is the highest for 100% renewable fraction scenario. • CO 2 emissions are reduced by 1232 tonnes/yr by switching from diesel to renewables. • The electricity cost is most sensitive to diesel price based on sensitivity analysis.

2013-03-31

The objective of this project was to enhance the water resource decision-making process with respect to oil and gas exploration/production activities on Alaska’s North Slope. To this end, a web-based software tool was developed to allow stakeholders to assemble, evaluate, and communicate relevant information between and amongst themselves. The software, termed North Slope Decision Support System (NSDSS), is a visually-referenced database that provides a platform for running complex natural system, planning, and optimization models. The NSDSS design was based upon community input garnered during a series of stakeholder workshops, and the end product software is freely available to all stakeholders via the project website. The tool now resides on servers hosted by the UAF Water and Environmental Research Center, and will remain accessible and free-of-charge for all interested stakeholders. The development of the tool fostered new advances in the area of data evaluation and decision support technologies, and the finished product is envisioned to enhance water resource planning activities on Alaska’s North Slope.

Objective: To determine the use pattern of sex selection drugs (SSDs in rural North India. Methods: An integrated qualitative and quantitative study was conducted in rural North India. A rapid population and hospital based survey of women in their early reproductive life was done in the study area to enlist the respondents. Few SSD samples were collected and analyzed. Results: SSDs were freely available from grocers, chemist shops and specific people in villages. These contained Shivalingi (Bryonia Laciniosa and Majuphal (Gtuercus infectoria. SSD use rate was 46% and 30% in community based and hospital based studies respectively. Use rate was significantly higher in women who did not have any son. Of the SSD samples and two individual ingredients analyzed by thin layer chromatography, 3 contained testosterone and one progesterone; one ingredient contained testosterone and the other natural steroids. Conclusion: Use of SSDs seems to be very common in North India. Implication of presence of steroids in SSDs needs further evaluation.

Mean annual precipitation explains spatiotemporal patterns of Cenozoic mammal beta diversity and latitudinal diversity gradients in North America.

Directory of Open Access Journals (Sweden)

Danielle Fraser

Full Text Available Spatial diversity patterns are thought to be driven by climate-mediated processes. However, temporal patterns of community composition remain poorly studied. We provide two complementary analyses of North American mammal diversity, using (i a paleontological dataset (2077 localities with 2493 taxon occurrences spanning 21 discrete subdivisions of the Cenozoic based on North American Land Mammal Ages (36 Ma--present, and (ii climate space model predictions for 744 extant mammals under eight scenarios of future climate change. Spatial variation in fossil mammal community structure (β diversity is highest at intermediate values of continental mean annual precipitation (MAP estimated from paleosols (∼ 450 mm/year and declines under both wetter and drier conditions, reflecting diversity patterns of modern mammals. Latitudinal gradients in community change (latitudinal turnover gradients, aka LTGs increase in strength through the Cenozoic, but also show a cyclical pattern that is significantly explained by MAP. In general, LTGs are weakest when continental MAP is highest, similar to modern tropical ecosystems in which latitudinal diversity gradients are weak or undetectable. Projections under modeled climate change show no substantial change in β diversity or LTG strength for North American mammals. Our results suggest that similar climate-mediated mechanisms might drive spatial and temporal patterns of community composition in both fossil and extant mammals. We also provide empirical evidence that the ecological processes on which climate space models are based are insufficient for accurately forecasting long-term mammalian response to anthropogenic climate change and inclusion of historical parameters may be essential.

Bartlett, Lynne M; Nowak, Madeleine J; Ho, Yikhong

2013-01-01

In Australia, faecal incontinence, the involuntary loss of liquid or solid stool with or without a person's awareness, has been reported in 8% of the South Australian and 11% of the urban New South Wales community-dwelling populations. Studies conducted in 2004 and 2005 reported faecal incontinence in more than 20% of colorectal and urogynaecological clinic patients at Townsville Hospital (a referral centre serving rural North Queensland). This prompted concern regarding the level of faecal incontinence in the community. The aim of this study was to investigate the prevalence of faecal incontinence in the North and Far North Queensland urban and rural communities. The sample size was based on the New South Wales postal surveys (11% prevalence). Higher rates were expected in North/Far North Queensland, so prevalence there was estimated at 12.1% (confidence interval ± 2%, ie the true level to be between 10.1% and 14.1%). The sample for each of the Townsville, Cairns (in Far North Queensland) and rural/remote settings was calculated at 1022. The database for the present study was compiled using a systematic randomised process selecting two private names from each column on each page of the Cairns and Townsville White Pages® (Cairns: 1112 urban, 481 rural, 226 remote; Townsville: 1049 urban, 432 rural, 320 remote). The questionnaire covered personal demographics, health/risk factors, bowel habits, nutrition (fibre and fluid intake) and physical activity. Faecal incontinence was defined as accidental leakage of solid or liquid stool in the past 12 months that was not caused by a virus, medication or contaminated food. To improve the response rate a participation incentive of a chance to win a $250 voucher or one of ten $50 vouchers was offered in the initial mail-out. The initial survey was mailed out in July 2007; two follow-up surveys were mailed out to non-responders in September 2007 and January 2008. One hundred randomly selected non-responders were telephoned in

Dinosaurs on the North Slope, Alaska: High latitude, latest cretaceous environments

Abundant skeletal remains demonstrate that lambeosaurine hadrosaurid, tyrannosaurid, and troodontid dinosaurs lived on the Alaskan North Slope during late Campanian-early Maestrichtian time (about 66 to 76 million years ago) in a deltaic environment dominated by herbaceous vegetation. The high ground terrestrial plant community was a mild- to cold-temperate forest composed of coniferous and broad leaf trees. The high paleolatitude (about 70?? to 85?? North) implies extreme seasonal variation in solar insolation, temperature, and herbivore food supply. Great distances of migration to contemporaneous evergreen floras and the presence of both juvenile and adult hadrosaurs suggest that they remained at high latitudes year-round. This challenges the hypothesis that short-term periods of darkness and temperature decrease resulting from a bolide impact caused dinosaurian extinction.

Palm harvest impacts in north-western South America

DEFF Research Database (Denmark)

Balslev, Henrik

2011-01-01

Tropical forests harbor thousands of useful plants that are harvested and used in subsistence economies or traded in local, regional or international markets. The effect on the ecosystem is little known, and the forests resilience is badly understood. Palms are the most useful group of plants...... in tropical American forests. This paper introduces a cross-disciplinary study of the effects of harvesting palm products from the tropical forests in north-western South America. The size of the resource is estimated through palm community studies in the different forest formations that determines the number...... of species and individuals of all palm species. The genetic structure of useful palm species is studied to determine how much harvesting of the species contributes to genetic erosion of its populations, and whether extraction can be made without harm. Almost all palm species are used in rural communities...

Toxocariasis in North America: a systematic review.

Directory of Open Access Journals (Sweden)

Rachel M Lee

2014-08-01

Full Text Available Toxocariasis is an important neglected tropical disease that can manifest as visceral or ocular larva migrans, or covert toxocariasis. All three forms pose a public health problem and cause significant morbidity in areas of high prevalence. To determine the burden of toxocariasis in North America, we conducted a systematic review of the literature following PRISMA guidelines. We found 18 articles with original prevalence, incidence, or case data for toxocariasis. Prevalence estimates ranged from 0.6% in a Canadian Inuit community to 30.8% in Mexican children with asthma. Commonly cited risk factors included: African-American race, poverty, male sex, and pet ownership or environmental contamination by animal feces. Increased prevalence of Toxocara spp. infection was linked in a group of case control studies conducted in Mexico to several high risk groups including waste pickers, asthmatic children, and inpatient psychiatry patients. Further research is needed to determine the true current burden of toxocariasis in North America; however the prevalence estimates gathered in this review suggest that the burden of disease is significant.

The in vivo measurement of radiocaesium activity in lambs

Sherlock, J.C.; Andrews, D.; Dunderdale, J.; Shaw, P.; Lally, A.

1988-01-01

Contamination of certain areas of the UK with radiocaesium from the Chernobyl accident led to restrictions being placed on the movement of lambs in these areas. To determine whether part of an area met the criteria for derestriction required the laboratory monitoring of meat from lambs sacrificed for the purpose. This was a slow process because there was no means of knowing which parts of an area had the lowest activity levels in lambs, that is where the chances of removing restrictions were the greatest. A rapid, simple and cheap method for the in vivo monitoring of caesium activity in lambs was developed. Correlation between the results from this method and in-laboratory measurements was reasonable. The method was used successfully to monitor lambs in Cumbria and north Wales during July and August 1986. (author)

program to continue to meet the evolving needs of the conservation community for information on bird population change. By setting clear goals, strategies, and measures of success, this plan provides a cohesive framework and vision for maintenance and development of the BBS. The plan identifies two major goals for the BBS, with a number of strategies and objectives to achieve these goals. Over the next 5 years, progress made in addressing each long-term goal and its associated 5-year strategies and objectives will gage the plan's success. Specific actions, projected outcomes, and measures of success related to accomplishing these are outlined in Table 1, with a timeline in Table 2. The two main goals for the program, with a summary of the strategies to achieve them, are: Goal 1: Collect scientifically credible measures of the status and trends of North American bird populations at continental and regional scales. The North American Breeding Bird Survey will continue to support North American natural resource conservation through the collection of scientifically credible measures of the status and trends of continental bird populations. While doing this, the BBS will work to improve the science behind the program to better meet its mission and the changing needs of the avian conservation community. In partnership with collaborators, the BBS will address detection probability bias and habitat bias, improve analytical methods, and more fully assess and account for observer quality. Moreover, the BBS will improve the quality and breadth of avian population data through strategic increases in route density and the establishment of a Mexican BBS program. Goal 2: Ensure BBS data and analytical results are widely available and easily accessible for use by the avian conservation and management communities. At the heart of the BBS lies a four-million-record database containing more than 40 years of data on more than 600 bird species. These data are of no valu

The edge of the North West European Shelf (NWES) is characterised by a steep continental slope and a northward flowing slope current. These topographic/hydrographic features separate oceanic water and shelf water masses hence potentially separate phytoplankton communities. The slope current may facilitate the advective transport of phytoplankton, with mixing at the shelf edge supporting nutrient supply and therefore phytoplankton production. On the west Scottish shelf in particular, little is known about the phytoplankton communities in and around the shelf break and adjacent waters. Hence, to improve our understanding of environmental drivers of phytoplankton communities, biological and environmental data were collected on seven cross-shelf transects across the Malin and Hebridean Shelves during autumn 2014. Density profiles indicated that shelf break and oceanic stations had a 100 m deep mixed surface layer while stations on the shelf were generally well mixed. Analysis of similarity and multidimensional scaling of phytoplankton counts revealed that phytoplankton communities on the shelf were significantly different to those found at the shelf break and at oceanic stations. Shelf stations were dominated by dinoflagellates, with diatoms contributing a maximum of 37% of cells. Shelf break and oceanic stations were also dinoflagellate dominated but displayed a lower species diversity. Significant difference between shelf and shelf break stations suggested that the continental slope limited cross shelf phytoplankton exchange. Northern and southern phytoplankton communities on the shelf were approximately 15% dissimilar while there was no latitudinal gradient for stations along the slope current, suggesting this current provided south to north connectivity. Fitting environmental data to phytoplankton ordination showed a significant relationship between phytoplankton community dissimilarities and nutrient concentrations and light availability on the shelf compared to

How will ecological communities change in response to climate warming? Direct effects of temperature and indirect cascading effects of species interactions are already altering the structure of local communities, but the dynamics of community change are still poorly understood. We explore the cumulative effects of warming on the dynamics and turnover of forest ant communities that were warmed as part of a 5-year climate manipulation experiment at two sites in eastern North America. At the community level, warming consistently increased occupancy of nests and decreased extinction and nest abandonment. This consistency was largely driven by strong responses of a subset of thermophilic species at each site. As colonies of thermophilic species persisted in nests for longer periods of time under warmer temperatures, turnover was diminished, and species interactions were likely altered. We found that dynamical (Lyapunov) community stability decreased with warming both within and between sites. These results refute null expectations of simple temperature-driven increases in the activity and movement of thermophilic ectotherms. The reduction in stability under warming contrasts with the findings of previous studies that suggest resilience of species interactions to experimental and natural warming. In the face of warmer, no-analog climates, communities of the future may become increasingly fragile and unstable.

Mapping Plant Diversity and Composition Across North Carolina Piedmont Forest Landscapes Using Lidar-Hyperspectral Remote Sensing

Science.gov (United States)

Hakkenberg, Christopher R.

Forest modification, from local stress to global change, has given rise to efforts to model, map, and monitor critical properties of forest communities like structure, composition, and diversity. Predictive models based on data from spatially-nested field plots and LiDAR-hyperspectral remote sensing systems are one particularly effective means towards the otherwise prohibitively resource-intensive task of consistently characterizing forest community dynamics at landscape scales. However, to date, most predictive models fail to account for actual (rather than idealized) species and community distributions, are unsuccessful in predicting understory components in structurally and taxonomically heterogeneous forests, and may suffer from diminished predictive accuracy due to incongruity in scale and precision between field plot samples, remotely-sensed data, and target biota of varying size and density. This three-part study addresses these and other concerns in the modeling and mapping of emergent properties of forest communities by shifting the scope of prediction from the individual or taxon to the whole stand or community. It is, after all, at the stand scale where emergent properties like functional processes, biodiversity, and habitat aggregate and manifest. In the first study, I explore the relationship between forest structure (a proxy for successional demographics and resource competition) and tree species diversity in the North Carolina Piedmont, highlighting the empirical basis and potential for utilizing forest structure from LiDAR in predictive models of tree species diversity. I then extend these conclusions to map landscape pattern in multi-scale vascular plant diversity as well as turnover in community-continua at varying compositional resolutions in a North Carolina Piedmont landscape using remotely-sensed LiDAR-hyperspectral estimates of topography, canopy structure, and foliar biochemistry. Recognizing that the distinction between correlation and

Full Text Available Formation of the North American Free Trade Area (NAFTA among the three countries - the U.S., Canada and Mexico is the most striking example of successful development of integration processes in the Western Hemisphere. This year NAFTA marks the 20th anniversary of its foundation (1994. NAFTA covers trade in goods, services and movement of capital, intellectual property rights, environmental cooperation and labor cooperation. Its main advantages for member countries related to the dynamic growth of regional trade and investments, promoting the growth of industrial production (capital-intensive and high-tech industries in the U.S. and Canada, and labor-intensive industries in Mexico, increase the investment attractiveness of the economies of member countries and the promotion of employment. But there are costs, both general and specific to the individual member countries. Common costs are primarily asymmetrical level of economic interdependence, where mutual economic relations are the most developed between the U.S. and Canada, the U.S. and Mexico, and the least developed between Mexico and Canada due to historical conditions. Other costs are the differentiation in the levels of economic development, in volumes of overall GDP and per capita, population and size of the territory. But despite the costs, integration processes are successfully developed and repeatedly raised the issue of deepening economic integration between the U.S., Canada and Mexico. So, in 2000, there was put forward the concept of creating the North American community as an economic and security community by 2010, and in 2005 proposed the idea of a common currency called the Amero. But these proposals did not come true. On the agenda - the possibility of signing a new, more expanded NAFTA+, and even in the last year - the possibility to form a customs union under NAFTA.

Totem and taboo in the grocery store: quasi-religious foodways in North America

Directory of Open Access Journals (Sweden)

Benjamin E. Zeller

2015-01-01

Full Text Available This article focuses on food proscriptions such as veganism and gluten-free eating, and prescriptions such as the Paleolithic diet, focusing on the North American context. These quasi-religious foodways serve as means for individuals to engage in discourses of community, personal and group identity, and boundary-marking. Through the daily practice of eating, those who follow quasi-religious foodways mark their identities, literally consuming who they are. These quasi-religious foodways therefore function to allow contemporary consumer-oriented individualistic Americans to engage in discourses of community, identity, and meaning in a highly vernacular manner, that of the marketplace. They also point to the manner in which identity and community have expanded well outside of religious categories.

Climate, fishery and society interactions: Observations from the North Atlantic

Science.gov (United States)

Hamilton, Lawrence C.

2007-11-01

Interdisciplinary studies comparing fisheries-dependent regions across the North Atlantic find a number of broad patterns. Large ecological shifts, disastrous to historical fisheries, have resulted when unfavorable climatic events occur atop overfishing. The "teleconnections" linking fisheries crises across long distances include human technology and markets, as well as climate or migratory fish species. Overfishing and climate-driven changes have led to a shift downwards in trophic levels of fisheries takes in some ecosystems, from dominance by bony fish to crustaceans. Fishing societies adapt to new ecological conditions through social reorganization that have benefited some people and places, while leaving others behind. Characteristic patterns of demographic change are among the symptoms of such reorganization. These general observations emerge from a review of recent case studies of individual fishing communities, such as those conducted for the North Atlantic Arc research project.

The impacts of lithologic structure and geothermal gradient on subseafloor microbial communities were investigated at a marginal site of the Iheya North hydrothermal field in the Mid-Okinawa Trough. Subsurface marine sediments composed of hemipelagic muds and volcaniclastic deposits were recovered through a depth of 151 m below the seafloor at site C0017 during Integrated Ocean Drilling Program Expedition 331. Microbial communities inferred from 16S rRNA gene clone sequencing in low-temperature hemipelagic sediments were mainly composed of members of the Chloroflexi and deep-sea archaeal group. In contrast, 16S rRNA gene sequences of marine group I Thaumarchaeota dominated the microbial phylotype communities in the coarse-grained pumiceous gravels interbedded between the hemipelagic sediments. Based on the physical properties of sediments such as temperature and permeability, the porewater chemistry, and the microbial phylotype compositions, the shift in the physical properties of the sediments is suggested to induce a potential subseafloor recharging flow of oxygenated seawater in the permeable zone, leading to the generation of variable chemical environments and microbial communities in the subseafloor habitats. In addition, the deepest section of sediments under high-temperature conditions (∼90°C) harbored the sequences of an uncultivated archaeal lineage of hot water crenarchaeotic group IV that may be associated with the high-temperature hydrothermal fluid flow. These results indicate that the subseafloor microbial community compositions and functions at the marginal site of the hydrothermal field are highly affected by the complex fluid flow structure, such as recharging seawater and underlying hydrothermal fluids, coupled with the lithologic transition of sediments.

2017-04-01

Despite the importance of arbuscular mycorrhizal (AM) fungi within terrestrial ecosystems, we know little about how natural AM fungal communities are structured. To date, the majority of studies examining AM fungal community diversity have focused on single habitats with similar environmental conditions, with relatively few studies having assessed the diversity of AM fungi over large-scale environmental gradients. In this study, we characterized AM fungal communities in the soil along a high-elevation gradient in the North American Rocky Mountains. We focused on phylogenetic patterns of AM fungal communities to gain insight into how AM fungal communities are naturally assembled. We found that alpine AM fungal communities had lower phylogenetic diversity relative to lower elevation communities, as well as being more heterogeneous in composition than either treeline or subalpine communities. AM fungal communities were phylogenetically clustered at all elevations sampled, suggesting that environmental filtering, either selection by host plants or fungal niches, is the primary ecological process structuring communities along the gradient.

Petroleum producers and Canada's north : an industry moving forward

International Nuclear Information System (INIS)

2000-11-01

Efforts were made by northern industries over the last 20 years to reduce their impact on the environment. The minimization of the footprint on the environment was researched and new exploration and production techniques were developed by petroleum companies, so that clean air, clear water, healthy land and abundant wildlife could be maintained in the north. An example of such techniques is provided by directional drilling technology, which enables oil and gas producers to assess reserves under lakes or other sensitive areas without leaving an impact. Everyone in the north benefits from the oil and gas industry as a result of local employment policies, increased government revenues. Job creation is probably the most obvious benefit derived from oil and gas activities in the north. At present, the jobs are mainly concentrated in the seismic field, drilling and support services sector, as the industry is in the exploration stage. As the industry evolves into the development phase, the jobs and business opportunities will also mature. Training programs are being created by the governments of the Northwest Territories and Canada in partnership with the petroleum industry to enable northern residents to take advantage of the new opportunities. The traditional economies of the north will be strengthened by a strong oil and gas industry. Industry and communities must be ready to share their vision of the north to develop a sustainable northern oil and gas industry. Abundant oil and gas resources are located in the Northwest Territories, and numerous challenges make getting the resources and moving them to market difficult. The Canadian Association of Petroleum Producers has a vision of a strong industry in the north employing local people and where the respect of local knowledge and traditions dominates. The members companies are responsible for the production of 95 per cent of the crude oil and natural gas in Canada. The Canadian Association of Petroleum Producers has a

Full Text Available Deciphering the ecological traits of abundant marine bacteria is a major challenge in marine microbial ecology. In the current study, we linked compositional and functional predictions to elucidate such traits for abundant bacterioplankton lineages in the North Sea. For this purpose, we investigated entire and active bacterioplankton composition along a transect ranging from the German Bight to the northern North Sea by pyrotag sequencing of bacterial 16S rRNA genes and transcripts. Functional profiles were inferred from 16S rRNA data using Tax4Fun. Bacterioplankton communities were dominated by well-known marine lineages including clusters/genera that are affiliated with the Roseobacter group and the Flavobacteria. Variations in community composition and function were significantly explained by measured environmental and microbial properties. Turnover of dissolved free amino acids (DFAA showed the strongest correlation to community composition and function. We applied multinomial models, which enabled us to identify bacterial lineages involved in DFAA turnover. For instance, the genus Planktomarina was more abundant at higher DFAA turnover rates, suggesting its vital role in amino acid degradation. Functional predictions further indicated that Planktomarina is involved in leucine and isoleucine degradation. Overall, our results provide novel insights into the biogeochemical significance of abundant bacterioplankton lineages in the North Sea.

Cultivating climate literacy among youth positions them to develop solutions and advocate for actions that prepare communities to adapt to climate change, mitigate emissions and ultimately protect human health and well-being, with an eye towards protecting the most vulnerable populations. This presentation will describe an innovative partnership among three university environmental health programs—based at the University of North Carolina at Chapel Hill, Columbia University and Harvard University—and their community collaborators: the Alliance for Climate Education, Boston Children's Hospital Pediatric Environmental Health Center and WE ACT for Environmental Justice. This project engages youth through non-formal educational programming that promotes climate literacy while also building the capacity of today's youth to promote community resilience. This partnership led to the development and implementation of two, long-duration extracurricular youth science enrichment programs in 2017, one in North Carolina (NC) and one in New York, with joint activities conducted virtually and in person to connect students with each other and with leading public health professionals and others working to promote community resilience and climate justice. Forty high school students, 20 from central NC and 20 from West Harlem in New York City, are enrolled in each program. In July 2017, students came together for a 3-day summer institute in NC. This session will feature the strategies, STEM-based activities and resources used in this project to engage students in the examination of their communities, identification and evaluation of climate adaptation and mitigation strategies and promotion of community resilience. Programming entailed having students interact with public health professionals, scientists and others to learn about climate impacts to public health and its infrastructure, vulnerable populations and planning for resilient communities. Ultimately, we sought to promote

The temporal community dynamics and persistence of different viral types in the marine environment are still mostly obscure. Polymorphism of the major capsid protein gene, g23, was used to investigate the community composition dynamics of T4-like myoviruses in a North Atlantic fjord for a period of 2 years. A total of 160 unique operational taxonomic units (OTUs) were identified by terminal restriction fragment length polymorphism (TRFLP) of the gene g23. Three major community profiles were identified (winter-spring, summer, and autumn), which resulted in a clear seasonal succession pattern. These seasonal transitions were recurrent over the 2 years and significantly correlated with progression of seawater temperature, Synechococcus abundance, and turbidity. The appearance of the autumn viral communities was concomitant with the occurrence of prominent Synechococcus blooms. As a whole, we found a highly dynamic T4-like viral community with strong seasonality and recurrence patterns. These communities were unexpectedly dominated by a group of persistently abundant viruses.

Diabetes is a growing epidemic in both urban and rural communities worldwide. We aimed to survey fasting plasma glucose (FPG) status and awareness of diabetes in the rural Karen ethnic community. We investigated the predictors of impaired fasting plasma glucose (IFG) status, which would be easily applicable for prevention of diabetes in a rural community. This was a community-based cross-sectional study conducted at Thasongyang, the most north-western district in Thailand. A total of 299 Karen ethnic rural residents were included in the study. FPG, body mass index, and waist circumference were prospectively measured. We assessed the awareness of diabetes and lifestyle-related health behavior with closed questionnaires in a rural community setting. On screening for FPG, 16.72% of the Karen ethnic residents had hyperglycemia: 3.68% in the diabetic range and 13.04% in the prediabetic range respectively. After adjustment for age, sex, and BMI, waist circumference (adjusted odds ratio [aOR] 3.5, 95% confidence interval [CI] 1.29-9.57), and having a diabetic blood relative (aOR 4.6, CI 1.81-11.71) are significant predictors of IFG status. It is necessary to promote awareness of diabetes among the Karen ethnic community. Application of simple evidence-based predictors of the prediabetic state may lead to timely and effective prevention of diabetes in rural settings.

Scepticism towards insecticide treated mosquito nets for malaria control in rural community in north-western Tanzania.

Nnko, Soori E; Whyte, Susan R; Geissler, Wenzel P; Aagaard-Hansen, Jens

2012-04-01

Despite existence of effective tools for malaria control, malaria continues to be one of the leading killer diseases especially among under-five year children and pregnant women in poor rural populations of Sub Saharan Africa. In Tanzania Mainland the disease contributes to 39.4% of the total OPD attendances. In terms of mortality, malaria is known to be responsible for more than one third of deaths among children of age below 5 years and also contributes for up to one fifth of deaths among pregnant women. This paper is based on a study conducted in a rural community along the shores of Lake Victoria in Mwanza region, North-Western Tanzania. The study explores reasons for scepticism and low uptake of insecticide treated mosquito nets (ITNs) that were promoted through social marketing strategy for malaria control prior to the introduction of long lasting nets (LLN). The paper breaks from traditional approach that tend to study low uptake of health interventions in terms of structural practical constraints--cost, accessibility, everyday priorities--or in terms of cognition--insufficient knowledge of benefits e.g. ignorance of public health messages. This paper has shown that, the majority of people who could afford the prices of ITNs and who knew where to obtain the insecticides did not necessarily buy them. This suggests that, although people tend to report cost-related factors as a barrier against the use of ITNs, there are other critical concerns at work. Without underestimating the practical factors, our study have recommended to consider critical examinations of those other concerns that hinder optimal utilization of ITN for malaria control, and the basis for those concerns.

Three trans-Atlantic oceanographic surveys (Nova Scotia to Canary Islands) were carried out during fall 1992 and spring 1993 to describe the large-scale variability in hydrographic, chemical and biological properties of the upper water column of the subtropical gyre and adjacent waters. Significant spatial and temporal variability characterized a number of the biological pools and rate processes whereas others were relatively invariant. Systematic patterns were observed in the zonal distribution of some properties. Most notable were increases (eastward) in mixed-layer temperature and salinity, depths of the nitracline and chlorophyll- a maximum, regenerated production (NH 4 uptake) and bacterial production. Dissolved inorganic carbon (DIC) concentrations, phytoplankton biomass, mesozooplankton biomass and new production (NO 3 uptake) decreased (eastward). Bacterial biomass, primary production, and community respiration exhibited no discernible zonal distribution patterns. Seasonal variability was most evident in hydrography (cooler/fresher mixed-layer in spring), and chemistry (mixed-layer DIC concentration higher and nitracline shallower in spring) although primary production and bacterial production were significantly higher in spring than in fall. In general, seasonal variability was greater in the west than in the east; seasonality in most properties was absent west of Canary Islands (˜20°W). The distribution of autotrophs could be reasonably well explained by hydrography and nutrient structure, independent of location or season. Processes underlying the distribution of the microheterophs, however, were less clear. Heterotrophic biomass and metabolism was less variable than autotrophs and appeared to dominate the upper ocean carbon balance of the subtropical North Atlantic in both fall and spring. Geographical patterns in distribution are considered in the light of recent efforts to partition the ocean into distinct "biogeochemical provinces".

Drilling occurs at three different drill centres of the White Rose (WR) oil platform that lies 350 km offshore from St. John's Newfoundland. An extensive environmental effects monitoring (EEM) program conducted by Husky Energy is underway at the WR site. The sediment component of the program involves the measurement of physical and chemical characteristics, an assessment of toxicity in laboratory tests, and an assessment of in situ benthic invertebrate communities. Baseline sampling occurred in 2000, followed by post-drilling sampling in 2004 to 2006. The sediment is 95 per cent sand, with polychaetes and bivalves dominating the invertebrate communities. A comparative evaluation was performed for regressions between community variables and distances from drill centres before and after drilling. Concentration-response relationships between community variables and concentrations of major constituents in drilling muds (C10-C21 HCs) were also compared among years. It was shown that the biological effects on invertebrate communities were highly restricted to reductions in the amount of Paraonidae and Amphipoda near drill centres and at higher C10-C21 HC concentrations. The study revealed that the two most abundant invertebrate communities were not influenced by drilling in terms of standing crop, richness, diversity and evenness.

The main security threats affecting the Middle East and North African (MENA) region arise from energy insecurity, immigration and terrorism. These threats would remain if authorities and other stake holders do not address the root causes of the problems, which are artificial national borders, authoritarian regimes and lack of pluralist education. This paper suggests that lifting state borders and setting up regional economic communities such as the EU may ease conflicts in the region which ca...

Total energy supply for remote human habitations (Or 'Nuclear North of 60')

International Nuclear Information System (INIS)

Harris, J.

2012-01-01

This presentation will examine the direct application of nuclear energy solutions in the north, and remote areas of Canada. Further it will challenge the existing energy network based on the shipment of fossil fuels to remote areas, and examine the use of small, modular, and/or deployable nuclear plants in these communities. The use of these small reactors and some newly emerging technologies will likely provide a near total energy supply for these communities. In particular low grade heat processes, district heating, the 'local' production of motive fuels, and local food production will be examined. Additionally the economic and social impact of moving the value added side of many of these processes to the local communities will also be briefly discussed.

Guidelines that Manitoba Hydro must follow in the preparation of the environmental impact statement on the proposed North Central Transmission Line (TCTL) project are presented. The project consists of a 138 kV transmission line, two 25 kV distribution lines, and related ancillary structures and facilities. The review process must be sensitive to cultural and community needs and must involve those most directly affected, and should be grounded in the impacted northern communities. The review should include a project background, the proposal, a description of the existing natural and socio-economic environment, and must address employment, education and training, impacts on renewable resource harvesting, environmental impacts, social impacts and economic impacts, legal/jurisdictional issues, infrastructure, mitigation and compensation, and environmental monitoring and follow-up. 1 fig., 20 tabs

2015-01-01

To determine the perception and attitudes of a rural community regarding the etiology, prevention, and treatment of blindness in adults. A cross-sectional, descriptive study was performed in a rural community in Kwara State, Nigeria using semi-structured questionnaire. All adults aged 40 years or older who were residents for a minimum of 6 months in the community were included. Data were collected on patient demographics, knowledge, attitude, perception, and use of the eye care facility. A total of 290 participants were interviewed. The male-to-female ratio was 1:2. Consumption of certain types of food was an important cause of blindness as perceived by 57.9% of the respondents, followed by supernatural forces (41.7%) and aging (19%). Sixty percent of respondents thought blindness could be prevented. Age (P = 0.04) and level of education (P =0.003) significantly affected the beliefs on the prevention of blindness. Most respondents (79.3%) preferred orthodox eye care, but only 65% would accept surgical intervention if required. The level of education significantly affected the acceptance of surgery (P = 0.04). Reasons for refusing surgery were, fear (64%), previous poor outcomes in acquaintances (31%), belief that surgery is not required (3%), and cost (2%). About 65% used one form of traditional eye medication or the other. Over half (56.6%) believed that spectacles could cure all causes of blindness. Of those who had ocular complaints, 57.1% used orthodox care without combining with either traditional or spiritual remedies. This rural Nigerian community had some beliefs that were consistent with modern knowledge. However, the overall knowledge, attitude, and perceptions of this community need to be redirected to favor the eradication of avoidable blindness. Although an eye care facility was available, use by the community was suboptimal. Age and the level of education affected their overall perception and attitudes.

Moore, Cordelia; Cappo, Mike; Radford, Ben; Heyward, Andrew

2017-09-01

This paper provides a first assessment of fish communities associated with the submerged oceanic banks and shoals in north-west Australia. Until recently, little was known about these deeper and more inaccessible reefs. The mesophotic coral-reef habitats (20-80 m) were a major reservoir of marine biodiversity, with unique and exceptionally high fish diversity and abundance. Species richness in the study region was 1.4 times, and abundance almost twice, that recorded for similar mesophotic habitats on the Great Barrier Reef in north-east Australia. A review of the published literature revealed that Australia's NW oceanic shoals support the highest fish species richness reported for mesophotic reefs to date. We made regional comparisons of fish community structure (species composition, richness and abundance) and assessed the influence of depth, substrate and location. The presence of consolidated calcareous reef, depth and aspect (a surrogate for exposure) had the greatest influence on species richness. In contrast, aspect and the presence of benthic biota had the greatest influence on fish abundance. Sites most exposed to the prevailing currents (facing north-east) had lowest fish abundance, while highest abundances were recorded on moderately exposed sites (along the north-west and south-east edges). The most abundant species were small ( Pomacentrus coelestis) and large ( Naso hexacanthus) planktivorous fish. Currently, 29.3% of NE Australia mesophotic reefs are within no-take management zones of the Great Barrier Reef. In contrast, just 1.3% of the NW oceanic shoals are designated as no-take areas. The location and extent of mesophotic reefs remain poorly quantified globally. Because these habitats support significant biodiversity and have the potential to act as important refugia, understanding their extent is critical to maintaining coral-reef biodiversity and resilience and supporting sustainable management.

2015-12-18

Climate change is predicted to alter marine phytoplankton communities and affect productivity, biogeochemistry, and the efficacy of the biological pump. We reconstructed high-resolution records of changing plankton community composition in the North Pacific Ocean over the past millennium. Amino acid-specific δ(13)C records preserved in long-lived deep-sea corals revealed three major plankton regimes corresponding to Northern Hemisphere climate periods. Non-dinitrogen-fixing cyanobacteria dominated during the Medieval Climate Anomaly (950-1250 Common Era) before giving way to a new regime in which eukaryotic microalgae contributed nearly half of all export production during the Little Ice Age (~1400-1850 Common Era). The third regime, unprecedented in the past millennium, began in the industrial era and is characterized by increasing production by dinitrogen-fixing cyanobacteria. This picoplankton community shift may provide a negative feedback to rising atmospheric carbon dioxide concentrations. Copyright © 2015, American Association for the Advancement of Science.

α-particle radioactivity of hot particles from the Esk estuary

International Nuclear Information System (INIS)

Hamilton, E.I.

1981-01-01

Transuranium radionuclides (Pu, Am and Cm) present in effluents discharged into the north-east Irish Sea by British Nuclear Fuels Limited, Windscale, Cumbria, UK, are found in sediment and biota of the Esk estuary approximately 10 km to the south. The site of the present investigation was at Newbiggin and the materials examined were suspended particulate debris samples at the sea surface, bottom sediments and some forms of biota collected in September 1977. It is shown here that hot particles (defined as small volumes of material emitting α particles recorded in a dielectric detector as dense clusters of tracks from a common origin) found in the estuary are likely to be original effluent debris derived from the processing of Magnox uranium fuel elements and not formed in situ as a result of natural processes common to the estuary.

Why Targets of Economic Sanctions React Differently: Reference Point Effects on North Korea and Libya

Directory of Open Access Journals (Sweden)

Jiyoun Park

2017-06-01

Full Text Available The international community has frequently introduced economic sanctions to curb the proliferation of weapons of mass destruction, to which each target nation has reacted differently. This paper explores the reasons why each target of economic sanctions reacts differently by specif- ically building a model based on reference point effects, and by analyzing the cases of North Korea and Libya. According to the results, when the reference point level increases, as in the case of North Korea, the target resists more firmly; on the other hand, when the reference point decreases, like in the case of Libya, the target resists more subtly.

Balancing Social Responsibility and Personal Autonomy: Adolescents' Reasoning About Community Service Programs.

Science.gov (United States)

McNeil, Justin; Helwig, Charles C

2015-01-01

Many jurisdictions in North America have implemented mandatory community service programs in high schools. However, little research exists examining the reasoning of youth themselves about such programs. This study examined how youth reason about community service programs, and how they balance the prosocial goals of these programs against their personal autonomy. Seventy-two participants between 10 and 18 years old evaluated voluntary community service along with 4 hypothetical mandatory programs that varied according to whether students or the government decided the areas in which students would serve, and whether a structured reflection component was included. The findings reveal that youth are not simply self-focused but rather balance and coordinate considerations of autonomy and community in their judgments and reasoning about community service.

Conservation of Mexican wetlands: role of the North American Wetlands Conservation Act

Science.gov (United States)

Wilson, M.H.; Ryan, D.A.

1997-01-01

Mexico's wetlands support a tremendous biological diversity and provide significant natural resource benefits to local communities. Because they are also critical stopover and wintering grounds for much of North America's waterfowl and other migratory birds, Mexico has become an important participant in continental efforts to conserve these resources through the North American Wetlands Conservation Act. Funding from the Act has supported partnerships in a number of Mexico's priority wetlands to conduct data analyses and dissemination, mapping, environmental education, wetland restoration, development of sustainable economic alternatives for local people, and reserve planning and management. These partnerships, with the close involvement of Mexico's Federal Government authority, the Instituto Nacional de Ecologia, have advanced conservation in a uniquely Mexican model that differs from that employed in the United States and Canada.

Planning for a soft landing : non-renewable resource development and community infrastructure in the Northwest Territories

International Nuclear Information System (INIS)

2006-02-01

This paper provided a high-level overview of research related to the boom and bust cycle of resource-based economic development and community infrastructure in the north, particularly in the Northwest Territories. The paper focused on what is known and on knowledge gaps that needed to be filled in each of 3 theme areas for an experts workshop on northern communities. The themes that were discussed at the workshop and in this paper were: the connections between non-renewable resources development and community infrastructure in the north; planning for resource development; and strategies for moving ahead and putting ideas into practice. The paper discussed the objectives of the research and discussed findings under each of the 3 themes. Topics discussed included: changes in the infrastructure mix; infrastructure and climate change; infrastructure financing; uncertainty; knowledge; planning tools; stakeholder participation; and measuring and monitoring planning implementation. Data availability was also discussed along with funding mechanisms, technological innovations and community capacity building. It was concluded that strategies for dealing with the boom-induced infrastructure challenges facing communities in the Northwest Territories should focus on making more creative use of available funding; promoting technical innovation; and improving maintenance capacity at the community level. 62 refs

Avian use of forest habitats in the Pembina Hills of northeastern North Dakota

Faanes, Craig A.; Andrew, Jonathan M.

1983-01-01

North Dakota has the least extensive total area of forested habitats of any of the 50 United States. Although occurring in limited area, forest communities add considerably to the total ecological diversity of the State. The forests of the Pembina Hills region in northeastern North Dakota are one of only three areas large enough to be considered of commercial value. During 1981 we studied the avifauna of the upper valley of the Pembina River in the Pembina Hills. Field work extended from 20 April to 23 July; breeding bird censuses were conducted 7 June to 2 July. Of the 120 bird species recorded during the study period, 79 species were recorded during the breeding season. The total breeding population was estimated at nearly 76,000 breeding pairs. The wood warblers (Parulidae) were the most numerous family, accounting for about 28,000 breeding pairs. The yellow warbler (Dendroica petechia) was the most abundant breeding species, making up 19.4% of the population. American redstart (Setophaga ruticilla) was second in abundance, accounting for 10.5% of the breeding population. Largest breeding densities occurred in the willow (Salix sp.) shrub community. Although supporting the lowest mean breeding density, quaking aspen (Populus tremuloides) forests supported the highest species diversity. First State breeding records were recorded for alder flycatcher (Empidonax alnorum) and golden-winged warbler (Vermivora chrysoptera). Records were obtained for 12 species considered rare or unusual in North Dakota during the breeding season. The status of all species known to have occurred in the study area is described in an annotated species list.

Ichthyoplankton Time Series: A Potential Ocean Observing Network to Provide Indicators of Climate Impacts on Fish Communities along the West Coast of North America

Science.gov (United States)

Koslow, J. A.; Brodeur, R.; Duffy-Anderson, J. T.; Perry, I.; jimenez Rosenberg, S.; Aceves, G.

2016-02-01

Ichthyoplankton time series available from the Bering Sea, Gulf of Alaska and California Current (Oregon to Baja California) provide a potential ocean observing network to assess climate impacts on fish communities along the west coast of North America. Larval fish abundance reflects spawning stock biomass, so these data sets provide indicators of the status of a broad range of exploited and unexploited fish populations. Analyses to date have focused on individual time series, which generally exhibit significant change in relation to climate. Off California, a suite of 24 midwater fish taxa have declined > 60%, correlated with declining midwater oxygen concentrations, and overall larval fish abundance has declined 72% since 1969, a trend based on the decline of predominantly cool-water affinity taxa in response to warming ocean temperatures. Off Oregon, there were dramatic differences in community structure and abundance of larval fishes between warm and cool ocean conditions. Midwater deoxygenation and warming sea surface temperature trends are predicted to continue as a result of global climate change. US, Canadian, and Mexican fishery scientists are now collaborating in a virtual ocean observing network to synthesize available ichthyoplankton time series and compare patterns of change in relation to climate. This will provide regional indicators of populations and groups of taxa sensitive to warming, deoxygenation and potentially other stressors, establish the relevant scales of coherence among sub-regions and across Large Marine Ecosystems, and provide the basis for predicting future climate change impacts on these ecosystems.

The livelihood of the people who live in the villages in coastal and remote areas can be developed into tourism area based on local wisdom to achieve sustainable tourism. Tunuo village is a village that has a wealth of Natural Resources and the Cultural Resources to support tourism. Nevertheless, Tunuo Village has problems related to Human Resources to support tourism. Meanwhile, the livelihood of Tunuo Village as producers of copra have constraints, namely access to economic capital. The gain from copra sale is erratic and prone to change, it encourages people to seek income from other options to meet their needs. These economic pressures encourage the development of environmentally damaging activities, such as fishing using homemade bombs so that reefs may be damaged. There are also other activities, such as the production, distribution, and consumption of traditional liquor made from palm tree sap, locally known as Saguer. Therefore, the present tourism as a sector that could provide opportunities for the villagers of Tunuo to earn extra income as well as efforts to preserve the environment, and culture. This research was conducted in the village of Tunuo, North Kao District, North Halmahera Regency, North Maluku province, Indonesia. The method is qualitative Participatory Action Research (PAR). The results indicate that people have a desire and a strong motivation to develop, so that the process of forming the Tourism Awareness Group (Pokdarwis) and its seven charms (saptapesona) can take place properly. As of the socialization of tourism awareness, as well as capacity building seminar for Pokdarwiswould be able to mobilize the community to clean up trash on the beach and to encourage communities to develop local knowledge into a leading tourism product.

Musser, Jonathan W.; Watson, Kara M.; Gotvald, Anthony J.

2017-05-05

The passage of Hurricane Matthew through central and eastern North Carolina during October 7–9, 2016, brought heavy rainfall, which resulted in major flooding. More than 15 inches of rain was recorded in some areas. More than 600 roads were closed, including Interstates 95 and 40, and nearly 99,000 structures were affected by floodwaters. Immediately following the flooding, the U.S. Geological Survey documented 267 high-water marks, of which 254 were surveyed. North Carolina Emergency Management documented and surveyed 353 high-water marks. Using a subset of these highwater marks, six flood-inundation maps were created for hard-hit communities. Digital datasets of the inundation areas, study reach boundary, and water-depth rasters are available for download. In addition, peak gage-height data, peak streamflow data, and annual exceedance probabilities (in percent) were determined for 24 U.S. Geological Survey streamgages located near the heavily flooded communities.

The Evolution of the North Korean Nuclear Crisis: Implications for Iran

International Nuclear Information System (INIS)

Chung Min, Lee

2009-01-01

The world today is confronted by North Korea that has apparently acquired successfully nuclear weapons, and by Iran that seems bent on acquiring, at a minimum, a virtual nuclear weapons capability. This trend suggests that prospects for freezing, if not rolling back, both Iran's and North Korea's programs are becoming increasingly difficult prospects. While President George W. Bush came under attack for going to war with Iraq based on faulty intelligence assessments and also for labeling Iran, Iraq and North Korea as part of the 'axis of evil', it cannot be denied that the world's 'most dangerous states with the most dangerous weapons' remain one of the defining security challenges of the post-9/11 era. Nevertheless, the Bush Administration's efforts to prevent, and failing that, to minimize the fallout from a nuclearized North Korea and a potentially nuclear capable Iran, have been decidedly mixed. Although North Korea maintained nuclear ambiguity for two decades, it finally gave up the pretense of having a 'virtual nuclear weapons program' in October 2006 whereas Iran continues on the path of nuclear brinkmanship. Whether Iran is going to cross the nuclear Rubicon remains uncertain but the fact that it has the requisite technologies and the political will to cross the nuclear threshold if it chose to do so remains unchanged. Regardless of Tehran's ultimate choice and attendant strategic consequences, Iran cannot but have gained key glimpses and insights from North Korea's decades-long pursuit of nuclear weapons. While Iran and North Korea have vastly different political histories and national ideologies, their paths have criss-crossed on the road towards nuclearization. Tehran and Pyongyang are not 'natural' allies although Iran has benefited from North Korea's ballistic missile sales (such as the Shahab-3 long-range missile). For its part, Pyongyang has gained not only from missile exports to Iran, but perhaps more significantly, by Iran's own nuclear challenge

Kamehameha Schools, in conjunction with several federal, state, and private organizations, has proposed to conduct conservation management on approximately 5,340 ha (~13,200 acres) of land they own in the vicinity of Kīpukalupea in the North Kona District on the island of Hawai'i. The goal of this program is to restore and enhance the habitat to benefit native plant and animal populations that are currently, or were formerly, found in this site. The initial phase of this project has been focused on various activities including conducting baseline surveys for bird and plant species so Kamehameha Schools could develop a Safe Harbor Agreement (SHA) for the proposed project lands relative to the habitat management and species reintroduction efforts they would like to conduct in the Lupea Project area. This report summarizes methods that were used to collect field data on plant species and communities within the project area, and the results of that initial survey. The information was used to calculate baseline values for all listed threatened or endangered plant species found, or expected to be found, within the project area, and to design a monitoring program to assess changes in plant communities and rare plant species relative to management activities over the duration of the SHA.

Full Text Available Whitebark pine (Pinus albicaulis has the largest and most northerly distribution of any white pine (Subgenus Strobus in North America, encompassing 18° latitude and 21° longitude in western mountains. Within this broad range, however, whitebark pine occurs within a narrow elevational zone, including upper subalpine and treeline forests, and functions generally as an important keystone and foundation species. In the Rocky Mountains, whitebark pine facilitates the development of krummholz conifer communities in the alpine-treeline ecotone (ATE, and thus potentially provides capacity for critical ecosystem services such as snow retention and soil stabilization. The invasive, exotic pathogen Cronartium ribicola, which causes white pine blister rust, now occurs nearly rangewide in whitebark pine communities, to their northern limits. Here, we synthesize data from 10 studies to document geographic variation in structure, conifer species, and understory plants in whitebark pine treeline communities, and examine the potential role of these communities in snow retention and regulating downstream flows. Whitebark pine mortality is predicted to alter treeline community composition, structure, and function. Whitebark pine losses in the ATE may also alter response to climate warming. Efforts to restore whitebark pine have thus far been limited to subalpine communities, particularly through planting seedlings with potential blister rust resistance. We discuss whether restoration strategies might be appropriate for treeline communities.

Full Text Available The population in the most Mediterranean countries, particularly in Algeria, is concentrated to the urban communities, cities with more or less importance, urban and coastal regions. This trend of rapid growth of the urban communities leads to multiple consequences both economically and socially on the use of resources and their distribution. The urban is the area where cross the resources, the population and the production activities and yours management. To analyze the corruption as a phenomenon triple (economic, social and institutional through an urban community (as Annaba’s case in this research it may well prove very fruitful in terms of lessons on this central phenomenon and its impacts in the North African countries.

Brokers, consumers and the internet: how North American consumers navigate their infertility journeys.

Speier, Amy R

2011-11-01

North Americans who suffer infertility often reach an end to treatment options at home, whether it is due to a lack of egg donors in Canada or the high cost of treatment in the USA. Patients navigate their way onto the internet, seeking support and other options. As women and couples 'do the research' online, they conduct endless Google searches, come across IVF brokers, join support groups, read blogs and meet others on the road of infertility. This paper considers the journeys that North American patients make to clinics in Moravia, Czech Republic. Along these travels, patients engage with support groups, other patients, IVF brokers and clinic co-ordinators. Since the distance travelled between North America and Europe is extensive, reproductive travels may be arranged by clinical staff, travel brokers and patients. Acting as consumers, North Americans make different 'choices' along their journeys – the use of a broker, if and when they should join online communities, which clinic to visit and where to stay. This study focuses on the question of how patient choices often determine the success of brokers and clinics, thus influencing the structure of cross-border reproductive care in the Czech Republic.

North Sea oil and the environment

International Nuclear Information System (INIS)

Cairns, W.J.

1992-01-01

This book, which is arranged in five sections, provides an historical record of the development of North Sea oil and gas over the past twenty years and records the lessons learnt from this experience. This first section provides an introductory framework to the three main themes, namely resources, environment and development. Section 2 is primarily concerned with the economic and social consequences of oil related development at two levels; firstly on the national economy and secondly the impact on local communities. Section 3 deals with impacts upon the physical environment and introduces the statutory land use planning system in Scotland. The Scottish approach to environmental assessment is reviewed and the need for mitigation by design explored. Section 4 examines specific field developments, and reviews the statutory controls and international initiatives regulating the extent of environmental disturbance and pollution from offshore operations. The effects of oil spillage and submarine pipelines on the environment and their impact on the fishing industry is followed by a discussion on the decommissioning and abandonment of offshore installations. Section 5 deals with the role and value of hazard and risk analysis in the siting, layout and safety zoning of onshore facilities and develops a case study on a major fractionation facility. The means of mitigating acute and chronic environmental risks are considered. A postscript provides a range of past comments and criticisms and finally draws some conclusions on the performance of environmental management and North Sea oil development. The North Sea oil and gas development experience proves that with wisdom, forethought and goodwill, industrial exploiters of natural resources can operate economically within legislative, policy, scientific, technical and design parameters without causing long-term irreversible environmental damage.

Poorer diets and subsequent higher rates of chronic disease among lower-income individuals may be partially attributed to reduced access to fresh fruits and vegetables (F&V) and other healthy foods. Mobile markets are an increasingly popular method for providing access to F&V in underserved communities, but evaluation efforts are limited. The purpose of this study was to determine the impact of Veggie Van (VV), a mobile produce market, on F&V intake in lower-income communities using a group randomized controlled trial. VV is a mobile produce market that sells reduced-cost locally grown produce and offers nutrition and cooking education. We recruited 12 sites in lower-income communities in North Carolina (USA) to host VV, randomizing them to receive VV immediately (intervention) or after the 6-month study period (delayed intervention control). Participants at each site completed baseline and follow-up surveys including F&V intake, perceived access to fresh F&V and self-efficacy for purchasing, preparing and eating F&V. We used multiple linear regression to calculate adjusted differences in outcomes while controlling for baseline values, education and clustering within site. Among 142 participants who completed the follow-up, baseline F&V intake was 3.48 cups/day for control and 3.33 for intervention. At follow-up, adjusted change in F&V consumption was 0.95 cups/day greater for intervention participants (p = 0.005), but was attenuated to 0.51 cups per day (p = 0.11) after removing extreme values. VV customers increased their F&V consumption by 0.41 cups/day (n = 30) compared to a 0.25 cups/day decrease for 111 non-customers (p = 0.04). Intervention participants did not show significant improvements in perceived access to fresh F&V, but increased their self-efficacy for working more F&V into snacks (p = 0.02), making up a vegetable dish with what they had on hand (p = 0.03), and cooking vegetables in a way that is appealing to their family (p�

Nutrition Information In Community Newspapers: Goal Framing, Story Origins, and Topics.

Science.gov (United States)

Andsager, Julie L; Chen, Li; Miles, Stephanie; Smith, Christina C; Nothwehr, Faryle

2015-01-01

Obesity rates are high in the rural United States. Because small communities often have few health care practitioners, nutrition news in community newspapers may be a useful source of information. This content analysis of a random sample of 164 nutrition stories from 10 community newspapers in the rural West North Central Midwest was guided by concepts from goal-framing theory. Locally generated stories comprised nearly half of the sample, suggesting that nutrition is a salient topic in many rural communities. Hedonic frames related to food enjoyment were twice as frequent as health improvement frames. Results suggest food promotion was the most common topic of nutrition stories, with guidelines for a healthy diet appearing about half as often. Stories about a healthy diet and food promotion were most often written locally. Findings are discussed with recommendations for improvement of community news coverage of nutrition.

Obesity has reached pandemic levels with more than 1.4 billion adults affected worldwide. While there is a need to systematically develop and evaluate community pharmacy based models of weight management, it is imperative to describe and understand the perspectives of pharmacy staff. In the UK, trained and accredited community pharmacy medicines counter assistants (MCAs) are commonly the front line staff involved in patient consultations and sale of over-the-counter medicines. To explore the beliefs and experiences of pharmacists and MCAs in the North-East of Scotland on community pharmacy weight management. All 135 community pharmacies in the North-East of Scotland. A qualitative approach of semi-structured telephone interviews with 31 pharmacists and 20 MCAs in the North-East of Scotland. The semi-structured interview schedule was developed with reference to key domains describing professional practice (i.e. awareness and knowledge, skills, practicalities, motivation, acceptance and beliefs) and contextualised with policy documents and published research on community pharmacy based weight management. Interviews were audio-recorded, transcribed and analysed thematically. Pharmacists' and MCAs' beliefs and experiences with delivering weight management services in community pharmacy. There were mixed responses from pharmacists and MCAs around pharmacy based weight management services from positive views of providing the service in community pharmacy to those more reticent who would always favour patients visiting their physician. While all described similar services e.g. measurement of weight, healthy eating advice, supply of products, they acknowledged that support was often opportunistic at the request of customers, with little integration of other providers. Roles described varied from pharmacist only functions to any staff member. While pharmacists generally felt comfortable and confident, MCAs gave more diverse responses. Both Pharmacist and MCAs highlighted

Coherent changes of wintertime surface air temperatures over North Asia and North America.

2018-03-29

The surface temperature variance and its potential change with global warming are most prominent in winter over Northern Hemisphere mid-high latitudes. Consistent wintertime surface temperature variability has been observed over large areas in Eurasia and North America on a broad range of time scales. However, it remains a challenge to quantify where and how the coherent change of temperature anomalies occur over the two continents. Here we demonstrate the coherent change of wintertime surface temperature anomalies over North Asia and the central-eastern parts of North America for the period from 1951 to 2015. This is supported by the results from the empirical orthogonal function analysis of surface temperature and temperature trend anomalies over the Northern Hemisphere extratropical lands and the timeseries analysis of the regional averaged temperature anomalies over North Asia and the Great Plains and Great Lakes. The Asian-Bering-North American (ABNA) teleconnection provides a pathway to connect the regional temperature anomalies over the two continents. The ABNA is also responsible for the decadal variation of the temperature relationship between North Asia and North America.

Canaries in the mine? Gay community, consumption and aspiration in neoliberal Washington, DC

Gay men have been implicated in neoliberal urban development strategies (e.g. the creative city) as a ‘canary’ population that forecasts growth. Paradoxically, both neoliberal re-development of North American inner-cities and the ways in which gay men become neoliberalised as individuals contribute to the dissolution of urban gay communities. In contrast to discourses of homonormativity, which suggest that gay men’s declining attachments to gay communities stem from new equalities and consequ...

Orisaremi, Titilayo Cordelia

2016-06-01

In this study, which was part of a larger project I undertook in North-central Nigeria, I explored the differences in the sexual health seeking behavior of Tarok women and men and how these differences affect the spread of HIV. With the help of three research assistants, I conducted 16 in-depth interviews and 24 focus group discussions in four Tarok communities in North-central Nigeria. I found certain negative effects of gender inequality on women's sexual health seeking behavior in particular, a situation that has adverse implications for HIV acquisition and transmission. I therefore concluded that addressing the challenges of gender inequality is imperative for a sustained fight against HIV and AIDS in Nigeria.

Carolina del Norte and the New South: Social Work Practice with New Latino Immigrant Communities

Directory of Open Access Journals (Sweden)

Lisa de Saxe Zerden

2013-09-01

Full Text Available Over the past decade, the Latino population in North Carolina has increased 111%. More than half of North Carolina Latinos are foreign-born and most face issues related to immigration, acculturation, and often, discrimination. This article provides a brief overview of the historical context in which social workers engaged with immigrant communities, and argues that the profession brings strengths and unique skills to address North Carolina’s Latino immigrant population, historically, and within the current context. Key social demographics of Latino populations, sociopolitical realities, as well as theoretical and methodological issues related to the complex needs of this diverse population group are addressed. Two examples of Latino vulnerability in North Carolina, HIV/AIDS and discriminatory local immigration enforcement practices, are discussed to further highlight the unique strengths and challenges social workers in North Carolina and the New South face when working with Latino immigrants.

The profession of pharmacy is expanding its involvement in public health, but few studies have examined pharmacists' delivery of public health services. To assess Iowa and North Dakota pharmacists' practices, frequency of public health service delivery, level of involvement in achieving the essential services of public health, and barriers to expansion of public health services in rural and urban areas. This study implemented an on-line survey sent to all pharmacists currently practicing pharmacy in Iowa and North Dakota. Overall, 602 valid responses were analyzed, 297 in rural areas and 305 in urban areas. Three practice settings (chain stores [169, 28.2%], independent community pharmacies [162, 27.0%], and hospital pharmacies [156, 26.0%]) comprised 81.2% of the sample. Both chain and independent community pharmacists were more commonly located in rural areas than in urban areas (PDakota. These findings should be interpreted to be primarily due to differences in the role of the rural pharmacist and the quest for certain opportunities that rural pharmacists are seeking.

Microorganisms likely mediate processes affecting the fate and impacts of marine plastic pollution, including degradation, chemical adsorption, and colonization or ingestion by macroorganisms. We investigated the relationship between plastic-associated microorganism communities and factors such as location, temperature, salinity, plankton abundance, plastic concentration, item size, surface roughness, and polymer type. Small plastic items from the surface of the North Pacific Gyre in 2011 were examined using scanning electron microscopy. Bacillus bacteria (mean 1664 ± 247 individuals mm(-2)) and pennate diatoms (1097 ± 154 mm(-2)) were most abundant, with coccoid bacteria, centric diatoms, dinoflagellates, coccolithophores, and radiolarians present. Bacterial abundance was patchy, but increased on foamed polystyrene. Diatom abundance increased on items with rough surfaces and at sites with high plastic concentrations. Morphotype richness increased slightly on larger fragments, and a biogeographic transition occurred between pennate diatom groups. Better characterizing this community will aid in understanding how it interacts with plastic pollution. Copyright © 2013 Elsevier Ltd. All rights reserved.

Community Earth System Model Simulations Reveal the Relative Importance of Afforestation and Forest Management to Surface Temperature in Eastern North America

Directory of Open Access Journals (Sweden)

Benjamin J. Ahlswede

2017-12-01

Full Text Available Afforestation changes the land surface energy balance, though the effects on climate in temperate regions is uncertain, particularly the changes associated with forest management. In this study, we used idealized Community Earth System Model simulations to assess the influence of afforestation and afforestation management in eastern North America on climate via changes in the biophysics of the land surface. Afforestation using broadleaf deciduous trees maintained at high leaf area index (LAI in the southern part of the study region provided the greatest climate benefit by cooling summer surface air temperatures (Tsa. In contrast, the greatest warming occurred in the northern extent of the study region when afforesting with needleleaf evergreen trees maintained at high LAI. Forest management had an equal or greater influence on Tsa than the overall decision to afforest land in the southern extent of the region. Afforestation had a greater influence on Tsa than forest management in the northern extent. Integrating our results, focused on biophysical processes, with other research quantifying carbon cycle sensitivity to management can help guide the use of temperate afforestation to optimize climate benefits. Further, our results highlight the potential importance of including forest management in simulations of past and future climate.

The role of microorganisms in the cycling of sedimentary organic carbon is a crucial one. To better understand relationships between molecular composition of a potentially bioavailable fraction of organic matter and microbial populations, bacterial and archaeal communities were characterized using pyrosequencing-based 16S rRNA gene analysis in surface (top 30 cm) and subsurface/deeper sediments (30–530 cm) of the Helgoland mud area, North Sea. Fourier Transform Ion Cyclotron Resonance Mass Spectrometry (FT-ICR MS) was used to characterize a potentially bioavailable organic matter fraction (hot-water extractable organic matter, WE-OM). Algal polymer-associated microbial populations such as members of the Gammaproteobacteria, Bacteroidetes, and Verrucomicrobia were dominant in surface sediments while members of the Chloroflexi (Dehalococcoidales and candidate order GIF9) and Miscellaneous Crenarchaeota Groups (MCG), both of which are linked to degradation of more recalcitrant, aromatic compounds and detrital proteins, were dominant in subsurface sediments. Microbial populations dominant in subsurface sediments (Chloroflexi, members of MCG, and Thermoplasmata) showed strong correlations to total organic carbon (TOC) content. Changes of WE-OM with sediment depth reveal molecular transformations from oxygen-rich [high oxygen to carbon (O/C), low hydrogen to carbon (H/C) ratios] aromatic compounds and highly unsaturated compounds toward compounds with lower O/C and higher H/C ratios. The observed molecular changes were most pronounced in organic compounds containing only CHO atoms. Our data thus, highlights classes of sedimentary organic compounds that may serve as microbial energy sources in methanic marine subsurface environments. PMID:26635758

Diversity of Butterflies (Lepidoptera) in Manembo-Nembo Wildlife Reserve, North Sulawesi, Indonesia.

Koneri, Roni; Maabuat, Pience V

The degradation of a habitat will affect the population of butterflies living in it. This study aims to analyse the diversity of butterflies in the area of Manembo-Nembo Wildlife Reserve, North Sulawesi. Employing purposive sampling, the study was conducted for five months. The collection of butterflies was done by using the sweeping technique, following the transect line applied randomly along 1000 m to three types of habitat (the primary forest, riverside in the forest and agricultural land). The species diversity was determined by using diversity index (Shannon-Wiener). The study identified 4 families, 44 species and 748 individual butterflies. Nymphalidae was a family predominantly found (71.12%), while the species mostly found was Ideopsis juventa tontoliensis (10.16%). Abundance (76.50), richness (20.25), diversity (2.66) and species evenness (0.88) were mostly found in riverside habitats in the forest, while the lowest was found in the primary forest. The similarities of butterfly communities in the different types of habitats indicate that the highest similarity index of butterfly communities is in the habitats of the primary forest and riverside in the forest wi a value of 80%. The highest diversity of butterflies in all types of habitats found in riverside. The high diversity of butterflies in the river is strongly influenced by the presence of vegetation as food and host plants of butterflies and this habitat should be conserved for the survival of the butterfly in a wildlife reserve Manembo-Nembo, North Sulawesi. It is expected that the results of this study could become important data of the diversity of butterflies and effects of changes of habitats on the diversity of butterflies in Manembo-Nembo Wildlife Reserve, North Sulawesi.

Nomads and pastoralists represent around 30% of the population of North East zone of Somalia (Puntland) and have very limited access to basic health including immunization. During the 2013-2014 polio outbreak in Somalia, an increase number of polio cases notified health services among these underserved communities highlighted the urgent need to devise innovative strategies to reach them. Harnessing the high demand for veterinary services among pastoralist communities, the Ministry of Health and the Ministry of Livestock, with support from UNICEF, WHO and FAO launched an integrated human and animal vaccination campaign on 19 October 2014. Over 30 days, 20 social mobilizers conducted shelter to shelter social mobilization and interpersonal communication for nomadic/pastoralist hamlets, 20 human vaccination teams, accompanied by local community elders, traveled with animal vaccination teams to administer polio and measles vaccination to pastoralist communities in the 5 regions of Puntland. 26,393 children (0 to 10 years) received Oral Polio Vaccine (OPV) out of which 34% for the first time ever; 23,099 were vaccinated against measles. and 12,556 Vitamin A. Despite various operational challenges and a significantly higher operational cost of $6.2 per child reached with OPV, the integrated human and animal vaccination campaign was effective in reaching the unvaccinated children from nomadic and pastoralist communities of Somalia.

Wildlife managers routinely seek to establish sustainable limits of sport harvest or other regulated forms of take while confronted with considerable uncertainty. A growing body of ecological research focuses on methods to describe and account for uncertainty in management decision-making and to prioritize research and monitoring investments to reduce the most influential uncertainties. We used simulation methods incorporating measures of demographic uncertainty to evaluate risk of overharvest and prioritize information needs for North American sea ducks (Tribe Mergini). Sea ducks are popular game birds in North America, yet they are poorly monitored and their population dynamics are poorly understood relative to other North American waterfowl. There have been few attempts to assess the sustainability of harvest of North American sea ducks, and no formal harvest strategy exists in the U.S. or Canada to guide management. The popularity of sea duck hunting, extended hunting opportunity for some populations (i.e., special seasons and/or bag limits), and population declines have led to concern about potential overharvest. We used Monte Carlo simulation to contrast estimates of allowable harvest and observed harvest and assess risk of overharvest for 7 populations of North American sea ducks: the American subspecies of common eider (Somateria mollissima dresseri), eastern and western populations of black scoter (Melanitta americana) and surf scoter (M. perspicillata), and continental populations of white-winged scoter (M. fusca) and long-tailed duck (Clangula hyemalis). We combined information from empirical studies and the opinions of experts through formal elicitation to create probability distributions reflecting uncertainty in the individual demographic parameters used in this assessment. Estimates of maximum growth (rmax), and therefore of allowable harvest, were highly uncertain for all populations. Long-tailed duck and American common eider appeared to be at high

Social exclusion is both cause and consequence of mental disorders. People with mental disorders (PWMD) are among the most socially excluded in all societies yet little is known about their experiences in North India. This qualitative study aims to describe experiences of exclusion and inclusion of PWMD in two rural communities in Uttar Pradesh, India. In-depth interviews with 20 PWMD and eight caregivers were carried out in May 2013. Interviews probed experiences of help-seeking, stigma, discrimination, exclusion, participation, agency and inclusion in their households and communities. Qualitative content analysis was used to generate codes, categories and finally 12 key themes. A continuum of exclusion was the dominant experience for participants, ranging from nuanced distancing, negative judgements and social isolation, and self-stigma to overt acts of exclusion such as ridicule, disinheritance and physical violence. Mixed in with this however, some participants described a sense of belonging, opportunity for participation and support from both family and community members. These findings underline the urgent need for initiatives that increase mental health literacy, access to services and social inclusion of PWMD in North India, and highlight the possibilities of using human rights frameworks in situations of physical and economic violence. The findings also highlight the urgent need to reduce stigma and take actions in policy and at all levels in society to increase inclusion of people with mental distress and disorders.

The intimate connection between the North Sea and the North Atlantic Ocean suggests that the variability of the CO2 system...... of the North Atlantic Ocean may, in part, be responsible for the observed variability of pH and CO2 in the North Sea. In this work, we demonstrate the role of the North Atlantic Oscillation (NAO), the dominant climate mode for the North Atlantic, in governing this variability.

The purpose of this study was to evaluate the feasibility of using a crowdsourcing contest to promote HIV cure research community engagement. Crowdsourcing contests are open calls for community participation to achieve a task, in this case to engage local communities about HIV cure research. Our contest solicited images and videos of what HIV cure meant to people. Contestants submitted entries to IdeaScale, an encrypted online contest platform. We used a mixed-methods study design to evaluate the contest. Engagement was assessed through attendance at promotional events and social media user analytics. Google Analytics measured contest website user-engagement statistics. Text from contest video entries was transcribed, coded and analysed using MAXQDA. There were 144 attendees at three promotional events and 32 entries from 39 contestants. Most individuals who submitted entries were black ( n =31), had some college education ( n =18) and were aged 18-23 years ( n =23). Social media analytics showed 684 unique page followers, 2233 unique page visits, 585 unique video views and an overall reach of 80,624 unique users. Contest submissions covered themes related to the community's role in shaping the future of HIV cure through education, social justice, creativity and stigma reduction. Crowdsourcing contests are feasible for engaging community members in HIV cure research. Community contributions to crowdsourcing contests provide useful content for culturally relevant and locally responsive research engagement.

resources (Yadoo et al., 2011), before considering how similar mixes could be developed for rural on-grid communities in the mainland UK. We adopt an interdisciplinary approach that combines quantitative methods (spatial analysis and calculated energy outputs) with secondary data sources to assess resource potential at the regional scale (resolution 1km2) to highlight areas with significant local resources for a mix of renewable energy technologies (Gormally et al., 2012). We then focus at the community-level and use a combination of primary qualitative data (questionnaires and interviews on community acceptance to technologies) and primary quantitative data (primary resource data to assess how renewable mixes may vary throughout the year eg. hourly, daily, monthly) to produce a portfolio of energy scenarios. The scenarios assess different 'supply side' options, including different scales and mixes of technology, 'demand side' options including business as usual and reduced demand, and resilience to change, for example extreme events (droughts, floods). Here we present a methodology and outputs for a case study community in the UK but will highlight how the approach may be adopted for use in other communities across Europe.

Christofi, N.; Philp, J.C.; West, J.M.; Robbins, J.E.

1984-03-01

Several used and disused mines in Britain have been analysed for microbial presence, content and activity. The sites sampled are located in Cornwall, Derbyshire and Cumbria. The mines in Cornwall can be called 'working' and were being operated at the time of sampling. The mine in Derbyshire was disused until recently re-opened by cavers while the mines in Cumbria had remained closed up to the time of sampling. Waters and solid materials have been sampled where detailed microbiology has been undertaken. In Cumbria a detailed description of structures of biological interest was carried out. Both heterotrophic and autotrophic microorganisms have been found in some waters and on mine walls. The actual content of each mine is different according to local conditions and chemistries. The results of the microbiological analyses are given. The origin of these microorganisms cannot be determined although it is likely that they have been introduced by water running down mine shafts from surface strata and/or from excavation processes. Activity measurements have shown that waters in some mines are organic carbon limited. There are indications from the working mines that such carbon would be available from autotrophic populations present within the ecosystem or from backfill material. (author)

The Evolution of the North Korean Nuclear Crisis: Implications for Iran

Energy Technology Data Exchange (ETDEWEB)

Chung Min, Lee

2009-07-01

The world today is confronted by North Korea that has apparently acquired successfully nuclear weapons, and by Iran that seems bent on acquiring, at a minimum, a virtual nuclear weapons capability. This trend suggests that prospects for freezing, if not rolling back, both Iran's and North Korea's programs are becoming increasingly difficult prospects. While President George W. Bush came under attack for going to war with Iraq based on faulty intelligence assessments and also for labeling Iran, Iraq and North Korea as part of the 'axis of evil', it cannot be denied that the world's 'most dangerous states with the most dangerous weapons' remain one of the defining security challenges of the post-9/11 era. Nevertheless, the Bush Administration's efforts to prevent, and failing that, to minimize the fallout from a nuclearized North Korea and a potentially nuclear capable Iran, have been decidedly mixed. Although North Korea maintained nuclear ambiguity for two decades, it finally gave up the pretense of having a 'virtual nuclear weapons program' in October 2006 whereas Iran continues on the path of nuclear brinkmanship. Whether Iran is going to cross the nuclear Rubicon remains uncertain but the fact that it has the requisite technologies and the political will to cross the nuclear threshold if it chose to do so remains unchanged. Regardless of Tehran's ultimate choice and attendant strategic consequences, Iran cannot but have gained key glimpses and insights from North Korea's decades-long pursuit of nuclear weapons. While Iran and North Korea have vastly different political histories and national ideologies, their paths have criss-crossed on the road towards nuclearization. Tehran and Pyongyang are not 'natural' allies although Iran has benefited from North Korea's ballistic missile sales (such as the Shahab-3 long-range missile). For its part, Pyongyang has gained not only from missile

Full Text Available This investigation, monk development experts: Using traditional knowledge to manage community development by monks in Isan, is a qualitative study with three primary aims:To study the background of community development by monks in Northeastern Thailand, to study the current state of community development by monks in Northeastern Thailand and to outline a set of guidelines for community development by monks in Northeastern Thailand. The research area for this investigation was purposively selected and was composed of nine communities in Northeastern Thailand. Results show that monks have been involved in community development since Buddhism first arrived in North-eastern Thailand and their role is now primarily separated into three areas: Faith, knowledge and practice. The results of this investigation can be considered by local temples, communities, government institutions and individual monks when deciding how to manage and administer community development by monks in Northeastern Thailand.

We assessed sediment coring, data acquisition, and publications from the North Pacific (north of 30° N) from 1951 to 2016. There are 2134 sediment cores collected by American, French, Japanese, Russian, and international research vessels across the North Pacific (including the Pacific subarctic gyre, Alaskan gyre, Japan margin, and California margin; 1391 cores), the Sea of Okhotsk (271 cores), the Bering Sea (123 cores), and the Sea of Japan (349 cores) reported here. All existing metadata associated with these sediment cores are documented here, including coring date, location, core number, cruise number, water depth, vessel metadata, and coring technology. North Pacific sediment core age models are built with isotope stratigraphy, radiocarbon dating, magnetostratigraphy, biostratigraphy, tephrochronology, % opal, color, and lithological proxies. Here, we evaluate the iterative generation of each published age model and provide comprehensive documentation of the dating techniques used, along with sedimentation rates and age ranges. We categorized cores according to the availability of a variety of proxy evidence, including biological (e.g., benthic and planktonic foraminifera assemblages), geochemical (e.g., major trace element concentrations), isotopic (e.g., bulk sediment nitrogen, oxygen, and carbon isotopes), and stratigraphic (e.g., preserved laminations) proxies. This database is a unique resource to the paleoceanographic and paleoclimate communities and provides cohesive accessibility to sedimentary sequences, age model development, and proxies.

Communities can play an important role in delivering public health programs to older adults, but they differ in the provision of local structures and resources. The community readiness (CR) approach applies a stage model of change to the community level and analyzes structures and the degree of willingness to take action on a health issue. This study compared the CR regarding the promotion of physical activity as part of healthy ageing for older adults among urban and rural communities in North-West Germany. A cross-sectional CR assessment with key respondents in 23 municipalities (11 urban and 12 rural communities) was conducted using a semi-structured interview. Interviews were scored across the five CR dimensions and global CR score was calculated (scores between 1 = no awareness and 9 = professionalization). Wilcoxon rank-sum test and hierarchical regression models were used to compare urban and rural communities. In total, 118 interviews were conducted (response rate 69.8%). On average, the communities showed moderate CR scores (4.9 ± 0.3; Range: 4.3–5.4; preplanning or preparation phase). The global CR score was slightly higher in rural than in urban communities (regression coefficient = 0.29, 95% confidence interval (CI): −0.02–0.59). The rural communities showed significantly higher CR scores in the ‘Knowledge of efforts’ dimension (0.70, 95% CI: 0.26–1.14) and in the ‘Knowledge of the issue’ (0.37, 95% CI: 0.04–0.70). Rural communities display a slightly higher CR level than urban communities. In the next step, targeted capacity building activities will be initiated among communities with low CR levels.

Staying in the Hood: Black Lesbian and Transgender Women and Identity Management in North Philadelphia.

Science.gov (United States)

Brooks, Siobhan

2016-12-01

The concept Don't Ask, Don't Tell regarding Black LGBT sexuality in Black communities has been an acceptable form of identity management for Black LGBT people. In other words, Black LGBT people are accepted as long as they are not vocal about their sexuality. However, this is changing with the issue of gay marriage, which is creating a space where Black LGBT people are more open about their gender identity and sexuality in heterosexual Black spaces. This new form of openness allows Black LGBT people to "stay in" their communities, as opposed to coming out. In this article I examine how Black LGBT women in North Philadelphia stay in their communities: being politically active regarding LGBT issues, disengaging from LGBT issues, passing, and educating straight Black people about issues affecting the Black LGBT community. I conclude with implications of staying in and intersectionality among Black heterosexual and LGBT women fighting for social change.

Strategy. North-Korean nuclear: endgame?

International Nuclear Information System (INIS)

Mirandol, Guylain de

2017-01-01

As North Korea performed new ballistic missile tests in February 2017, and thus violated UN resolutions, this article proposes an overview of the evolutions from nuclear sanctions to economic sanctions. Initially, UN sanctions aimed at struggling against nuclear programmes and proliferation through embargo on arms and materials. After a nuclear test in 2016, South Korea withdrew from a North Korean industrial complex. International sanctions now aim at economically isolating North Korea, at increasing its trade deficit, and at reducing the sending of currencies by North-Korean expatriates. The author notices that these sanctions do not alter manufacturing activities, and that North Korea thus keeps on developing and being integrated into the international division of labour. The last part briefly discusses how North Korea could be able to get around sanctions

2004-03-01

Community involvement in education has been viewed as a - by no means uncontroversial - means for enabling local members to deepen their participation in the decision-making relevant to their schools by playing a constructive role in the process. On the basis of a study carried out in Ghana, the present contribution to this discussion examines various matters involved in delegating the management of an Alternative Primary Education program to two traditional communities in the north of that country. It also explores how community members, school authorities, the sponsoring non-governmental organization and members of the local management committee themselves perceive such an approach to school management. Issues raised include whether inexperienced and even illiterate local citizens should be allowed to manage their schools, the conflicts which such management often entails and, finally, in what ways it might be beneficially promoted.

Full Text Available Land units for the 900 km- Hluhluwe-Corridor-Umfolozi Game Reserve Complex in north eastern Natal were identified on aerial photographs. The physiognomy, dominants and description of the woody vegetation for each unit were identified during ground inspections and. where necessary, the point-centred quarter method was applied. Two forest, two riverine forest, ten woodland and two thicket communities were recognized. These communities are described according to their distribution, height and percentage frequency of the components in the different canopy strata. A map at a scale of 1:25 000 was also compiled. Some of these communities are compared with other similar woodlands previously described for Natal. In some communities the frequency of certain dominant canopy species in the under tree strata was extremely low and autecological research has been suggested.

2017-11-01

Although metazoan animals in the mesopelagic zone play critical roles in deep pelagic food webs and in the attenuation of carbon in midwaters, the diversity of these assemblages is not fully known. A metabarcoding survey of mesozooplankton diversity across the epipelagic, mesopelagic and upper bathypelagic zones (0-1500 m) in the North Pacific Subtropical Gyre revealed far higher estimates of species richness than expected given prior morphology-based studies in the region (4,024 OTUs, 10-fold increase), despite conservative bioinformatic processing. Operational taxonomic unit (OTU) richness of the full assemblage peaked at lower epipelagic-upper mesopelagic depths (100-300 m), with slight shoaling of maximal richness at night due to diel vertical migration, in contrast to expectations of a deep mesopelagic diversity maximum as reported for several plankton groups in early systematic and zoogeographic studies. Four distinct depth-stratified species assemblages were identified, with faunal transitions occurring at 100 m, 300 m and 500 m. Highest diversity occurred in the smallest zooplankton size fractions (0.2-0.5 mm), which had significantly lower % OTUs classified due to poor representation in reference databases, suggesting a deep reservoir of poorly understood diversity in the smallest metazoan animals. A diverse meroplankton assemblage also was detected (350 OTUs), including larvae of both shallow and deep living benthic species. Our results provide some of the first insights into the hidden diversity present in zooplankton assemblages in midwaters, and a molecular reappraisal of vertical gradients in species richness, depth distributions and community composition for the full zooplankton assemblage across the epipelagic, mesopelagic and upper bathypelagic zones. © 2017 The Authors.

Influences of introduced plague on North American mammals: Implications from ecology of plague in Asia

Science.gov (United States)

Biggins, D.E.; Kosoy, M.Y.

2001-01-01

Intercontinental movements of invasive species continue to modify the world's ecosystems. The plague bacterium (Yersinia pestis) has colonized and altered animal communities worldwide but has received much more attention as a human pathogen. We reviewed studies on the ecology of Y. pestis in ancient foci of central Asia and in western North America, where the bacterium apparently has become established much more recently. Although rodent populations on both continents are affected dramatically by epizootics of plague, the epidemiologically important species of Asia demonstrate resistance in portions of their populations, whereas those of North America are highly susceptible. Individual variation in resistance, which is widespread in Asian rodents and allows a microevolutionary response, has been documented in few North American species of rodents. Plague increases costs of sociality and coloniality in susceptible hosts, increases benefits of disease resistance in general, and increases benefits of adaptability to variable environments for species at higher trophic levels. Prairie dogs (Cynomys) epitomize taxa with high risk to plague because prairie dogs have uniformly low resistance to plague and are highly social. Relationships to plague are poorly understood for many North American rodents, but more than one-half of the species of conservation concern occur within the geographic range of plague.

Seasonal variation in the copepod gut microbiome in the subtropical North Atlantic Ocean.

Shoemaker, Katyanne M; Moisander, Pia H

2017-08-01

Characterisation of marine copepod gut microbiome composition and its variability provides information on function of marine food webs, biogeochemical cycles and copepod health. Copepod gut microbiomes were investigated quarterly over two years at the Bermuda Atlantic Time-series Station in the North Atlantic Subtropical Gyre, while assessing seasonal shifts in stable and transient communities. Microbial communities were analysed using amplicon sequencing targeting the bacterial 16S rRNA V3-V4 region and the cyanobacterial ntcA gene. Persistent bacterial groups belonging to Firmicutes, Bacteroidetes and Actinobacteria were present in the copepod guts throughout the year, and showed synchronous changes, suggesting a link to variability in copepod nutritional content. The gut communities were separate from those in the seawater, suggesting the copepod gut hosts long-term, specialized communities. Major temporal variations in the gut communities during the early winter and spring, specifically a high relative abundance of Synechococcus (up to 65%), were attributed to bacterioplankton shifts in the water column, and copepod grazing on these picoplanktonic cyanobacteria. The presence of obligate and facultative anaerobes, including Clostridiales year round, suggests that anaerobic bacterial processes are common in these dynamic microhabitats in the oligotrophic open ocean. © 2017 Society for Applied Microbiology and John Wiley & Sons Ltd.

Benthic megafaunal community structure of cobalt-rich manganese crusts on Necker Ridge

Morgan, Nicole B.; Cairns, Stephen; Reiswig, Henry; Baco, Amy R.

2015-10-01

In the North Pacific Ocean, the seamounts of the Hawaiian Archipelago and the Mid-Pacific Mountains are connected by Necker Ridge, a 600 km-long feature spanning a depth range of 1400-4000 m. The Necker Ridge is a part of a large area of the central and western Pacific under consideration for cobalt-rich manganese crust mining. We describe the fauna and community structure of the previously unsampled Necker Ridge based on explorations with the submersible Pisces IV. On five pinnacles and a portion of the Ridge ranging from 1400 to 2000 m deep, 27 transects were recorded using HD video, and voucher specimens were collected to aid in species identification. The video was analyzed to identify and count the megafauna found on each transect and to characterize the substrate. Diversity increased from south to north along the feature. There was a significant difference in community structure between southern and northern pinnacles, with southern pinnacles dominated by crinoids of the Family Charitometridae and northern pinnacles dominated by octocorals, especially the Families Isididae and Chrysogorgiidae. DistLM demonstrated a correlation between community structure on the pinnacles and at least six environmental variables, including latitude, sediment cover, and oxygen concentration, but not including depth. The discontinuous and patchy nature of these distinct megafaunal communities highlights growing evidence that cobalt-rich seamounts are highly heterogeneous habitats, and that managing seamounts may require more complex regulations than treating them as a single ecological unit. These results suggest that extensive community analysis should occur at a given site to determine management priority areas, prior to consideration of that site for exploitation of natural resources.

The North Carolina State Health Plan provides health care coverage to more than 700,000 members, including teachers, state employees, retirees, current and former lawmakers, state university and community college personnel, and their dependents. The State Health Plan is a division of the North Carolina Department of State Treasurer, self-insured, and exempt from the Employee Retirement Income Security Act as a government-sponsored plan. With health care costs rising at rates greater than funding, the Plan must take measures to stem cost growth while ensuring access to quality health care. The Plan anticipates focusing on strategic initiatives that drive results and cost savings while improving member health to protect the Plan's financial future. ©2018 by the North Carolina Institute of Medicine and The Duke Endowment.

Nitrogen-fixing microorganisms (diazotrophs) provide biologically available nitrogen to plankton communities and thereby greatly influence the productivity in many marine regions. Various cyanobacterial groups have traditionally been considered the major oceanic diazotrophs, but later noncyanobacterial and presumably heterotrophic diazotrophs were also found to be widespread and potentially important in nitrogen fixation. However, the distribution and activity of different diazotroph groups is still poorly constrained for most oceanic ecosystems. Here we examined diazotroph community structure and activity along a 7500 km south-north transect between the central equatorial Pacific and the Bering Sea. Nitrogen fixation contributed up to 84% of new production in the upper waters of the subtropical gyre, where the diazotroph community included the gammaproteobacterium γ-24774A11 and highly active cyanobacterial phylotypes (>50% of total nifH transcript abundance). Nitrogen fixation was sometimes detectable down to 150 m depth and extended horizontally to the edge of the gyre at around 35°N. Nitrogen fixation was even detected far north on the Bering Sea shelf. In the Alaskan Coastal Waters on the Bering Sea shelf, low nitrate together with high dissolved iron concentrations seemed to foster diazotroph growth, including a prominent role of UCYN-A2, which was abundant near the surface (1.2×105 nifH gene copies L-1). Our study provides evidence for nitrogen fixation in the Bering Sea and suggests a clear contrast in the composition of diazotrophs between the tropical/subtropical gyre and the separate waters in the cold northern regions of the North Pacific.

Analysis of ecosystem functioning is essential to describe the ecological status of ecosystems and is therefore directly requested in international directives. There is a lack of knowledge regarding functional aspects of benthic communities and their environmental and anthropogenic driving forces in the southern North Sea. This study linked functional composition of epibenthic communities to environmental conditions and fishing effort and investigated spatial correlations between habitat characteristics to gain insight into potential synergistic and/or cumulative effects. Functional composition of epifauna was assessed by using biological trait analysis (BTA), which considered 15 ecological traits of 54 species. Functional composition was related to ten predictor variables derived from sediment composition, bottom temperature and salinity, hydrodynamics, annual primary production and fishing effort. Our results revealed significantly different functional composition between the Dogger Bank, the Oyster Ground, the West and North Frisian coast. Mobility, feeding type, size and adult longevity were the most important traits differentiating the communities. A high proportion of trait modalities related to an opportunistic life mode were obvious in coastal areas especially at the West Frisian coast and in the area of the Frisian Front indicating disturbed communities. In contrast, functional composition in the Dogger Bank area indicated undisturbed communities with prevalence of large, long-lived and permanently attached species being sensitive towards disturbance such as fishing. Tidal stress, mud content of sediments, salinity, stratification and fishing effort were found to be the most important habitat characteristics shaping functional composition. Strong correlations were found between variables, especially between those which changed gradually from the coast to offshore areas including fishing effort.

Dangerously cold weather threatens life and property. During periods of extreme cold due to wind chill, the National Weather Service (NWS) issues wind chill warnings to prompt the public to take action to mitigate risks. Wind chill warnings are based on ambient temperatures and wind speeds. Since 2010, NWS has piloted a new extreme cold warning issued for cold temperatures in wind and nonwind conditions. The North Dakota Department of Health, NWS, and the Centers for Disease Control and Prevention collaborated in conducting household surveys in Burleigh County, North Dakota, to evaluate this new warning. The objectives of the evaluation were to assess whether residents heard the new warning and to determine if protective behaviors were prompted by the warning. This was a cross-sectional survey design using the Community Assessment for Public Health Emergency Response (CASPER) methodology to select a statistically representative sample of households from Burleigh County. From 10 to 11 April 2012, 188 door-to-door household interviews were completed. The CASPER methodology uses probability sampling with weighted analysis to estimate the number and percentage of households with a specific response within Burleigh County. The majority of households reported having heard both the extreme cold and wind chill warnings, and both warnings prompted protective behaviors. These results suggest this community heard the new warning and took protective actions after hearing the warning.

Background: The profession of pharmacy is expanding its involvement in public health, but few studies have examined pharmacists’ delivery of public health services. Objective: To assess Iowa and North Dakota pharmacists’ practices, frequency of public health service delivery, level of involvement in achieving the essential services of public health, and barriers to expansion of public health services in rural and urban areas. Methods: This study implemented an on-line survey sent to all pharmacists currently practicing pharmacy in Iowa and North Dakota. Results: Overall, 602 valid responses were analyzed, 297 in rural areas and 305 in urban areas. Three practice settings (chain stores [169, 28.2%], independent community pharmacies [162, 27.0%], and hospital pharmacies [156, 26.0%]) comprised 81.2% of the sample. Both chain and independent community pharmacists were more commonly located in rural areas than in urban areas (PDakota. These findings should be interpreted to be primarily due to differences in the role of the rural pharmacist and the quest for certain opportunities that rural pharmacists are seeking. PMID:28042356

Fish and phytoplankton exhibit contrasting temporal species abundance patterns in a dynamic north temperate lake.

Gretchen J A Hansen

Full Text Available Temporal patterns of species abundance, although less well-studied than spatial patterns, provide valuable insight to the processes governing community assembly. We compared temporal abundance distributions of two communities, phytoplankton and fish, in a north temperate lake. We used both 17 years of observed relative abundance data as well as resampled data from Monte Carlo simulations to account for the possible effects of non-detection of rare species. Similar to what has been found in other communities, phytoplankton and fish species that appeared more frequently were generally more abundant than rare species. However, neither community exhibited two distinct groups of "core" (common occurrence and high abundance and "occasional" (rare occurrence and low abundance species. Both observed and resampled data show that the phytoplankton community was dominated by occasional species appearing in only one year that exhibited large variation in their abundances, while the fish community was dominated by core species occurring in all 17 years at high abundances. We hypothesize that the life-history traits that enable phytoplankton to persist in highly dynamic environments may result in communities dominated by occasional species capable of reaching high abundances when conditions allow. Conversely, longer turnover times and broad environmental tolerances of fish may result in communities dominated by core species structured primarily by competitive interactions.

Homo habitus: agency, structure and the transformation of tradition in the constitution of the TRB foraging-farming communities in the North European plain (ca 4500–2000 BC

Directory of Open Access Journals (Sweden)

2005-12-01

Full Text Available The current generally accepted view of the dispersal of farming into Europe is that farming groups in the eastern Mediterranean colonised selectively optimal farming areas. The role of contact between indigenous hunter-gatherers and incoming farmers was very important to the operation of this process. This general view of the spread of farming at a broad inter-regional scale gives us our understanding of the origins of the Neolithic but merits closer examination at the local and regional level, as increasingly it is becoming apparent that the causes and motivations may have differed. In this paper, Mesolithic to Neolithic communities with evidence of the transition from hunter-gatherer to farmer will be examined at a regional scale, in the central part of the north European plain, focussing on Kujavia. Additionally, the theory of structuration will be applied in order to elucidate the transition process at this level.

Species distribution models (SDMs) assume species exist in isolation and do not influence one another's distributions, thus potentially limiting their ability to predict biodiversity patterns. Community-level models (CLMs) capitalize on species co-occurrences to fit shared environmental responses of species and communities, and therefore may result in more robust and transferable models. Here, we conduct a controlled comparison of five paired SDMs and CLMs across changing climates, using palaeoclimatic simulations and fossil-pollen records of eastern North America for the past 21 000 years. Both SDMs and CLMs performed poorly when projected to time periods that are temporally distant and climatically dissimilar from those in which they were fit; however, CLMs generally outperformed SDMs in these instances, especially when models were fit with sparse calibration datasets. Additionally, CLMs did not over-fit training data, unlike SDMs. The expected emergence of novel climates presents a major forecasting challenge for all models, but CLMs may better rise to this challenge by borrowing information from co-occurring taxa.

Full Text Available We assessed sediment coring, data acquisition, and publications from the North Pacific (north of 30° N from 1951 to 2016. There are 2134 sediment cores collected by American, French, Japanese, Russian, and international research vessels across the North Pacific (including the Pacific subarctic gyre, Alaskan gyre, Japan margin, and California margin; 1391 cores, the Sea of Okhotsk (271 cores, the Bering Sea (123 cores, and the Sea of Japan (349 cores reported here. All existing metadata associated with these sediment cores are documented here, including coring date, location, core number, cruise number, water depth, vessel metadata, and coring technology. North Pacific sediment core age models are built with isotope stratigraphy, radiocarbon dating, magnetostratigraphy, biostratigraphy, tephrochronology, % opal, color, and lithological proxies. Here, we evaluate the iterative generation of each published age model and provide comprehensive documentation of the dating techniques used, along with sedimentation rates and age ranges. We categorized cores according to the availability of a variety of proxy evidence, including biological (e.g., benthic and planktonic foraminifera assemblages, geochemical (e.g., major trace element concentrations, isotopic (e.g., bulk sediment nitrogen, oxygen, and carbon isotopes, and stratigraphic (e.g., preserved laminations proxies. This database is a unique resource to the paleoceanographic and paleoclimate communities and provides cohesive accessibility to sedimentary sequences, age model development, and proxies.

2012-11-01

Full Text Available This paper examines the rise and fall of public housing in North America in order to explore the principle of sustainability. By extension, it addresses the concept of sustainability as it relates to the city. Urbanity is simultaneously the most and least sustainable form of development. While extremely sustainable from the point of view of density (economies of scale, efficient use ofinfrastructure, etc., it is highly vulnerable to social, political and economic forces. Such forces can easily trump the environmental sustainability of any building or community.The death and transfiguration of key portions of our public housing stock provides insights into this phenomenon – for which I will use Toronto’s Regent Park as a case study. The redevelopment ofthis 69-acre parcel aims to transform a failed social vision into a model for sustainable community development.

Detecting vegetation-precipitation feedbacks in mid-Holocene North Africa from two climate models

Using two climate-vegetation model simulations from the Fast Ocean Atmosphere Model (FOAM) and the Community Climate System Model (CCSM, version 2), we investigate vegetation-precipitation feedbacks across North Africa during the mid-Holocene. From mid-Holocene snapshot runs of FOAM and CCSM2, we detect a negative feedback at the annual timescale with our statistical analysis. Using the Monte- Carlo bootstrap method, the annual negative feedback is further confirmed to be significant in both simulations. Additional analysis shows that this negative interaction is partially caused by the competition between evaporation and transpiration in North African grasslands. Furthermore, we find the feedbacks decrease with increasing timescales, and change signs from positive to negative at increasing timescales in FOAM. The proposed mechanism for this sign switch is associated with the different persistent timescales of upper and lower soil water contents, and their interactions with vegetation and atmospheric precipitation.

In 1985, the population of the Democratic People's Republic of Korea (North Korea) stood at 20 million, with an annual growth rate of 2.3%. The infant mortality rate was 30/1000 live births and life expectancy was 66 years. The gross national product (GNP) was US$23 billion in 1984, with a per capita GNP of $1175. Both North Korea's labor force and natural resources have been concentrated in recent years on an effort to achieve rapid economic development. During the early 1970s, a large-scale modernization program involving the importation of Western technology, primarily in the heavy industiral sectors of the economy, was attempted and resulted in a massive foreign debt. North Korea has a strongly centralized government under the control of the communist Korean Workers' Party. Literacy in the country is at the 99% level. Medical treatment is free. There is 1 physician/600 population and 1 hospital bed/350 inhabitants.

Full Text Available Abstract Background Despite the policy principle that “children are best cared for at home whenever possible” children continue to have high rates of emergency department (ED attendance and emergency hospital admission. Community Children’s Nursing Teams (CCNTs can care for acutely ill children at home but their potential to provide an alternative to ED attendance and hospitalisation depends on effective integration with other services in the urgent care system, such as EDs and Observation and Assessment Units (OAUs. Although challenges of integrating CCNTs have been identified, there has been no comparative assessment of the factors that facilitate or hinder integration of care of acutely ill children by CCNTs with the urgent care system. The aim of this study was to identify enablers and barriers to integration of CCNTs with urgent and emergency care. Methods Comparative case studies were conducted of two CCNTs serving Primary Care Trusts in North West England. Twenty-two health professionals including CCNT managers and staff; paediatricians; nurses; children’s ward, ED and OAU staff; commissioners of children’s services; GPs and primary care staff were interviewed between June 2009 and February 2010. Qualitative data were analysed thematically using the Framework approach. Results Barriers to integration included paediatricians’ perceived lack of ownership of the CCNT, poor communication between consultants and community children’s nurses (CCNs, and weak personal relationships. This prevented early referral to the CCNT as an alternative to hospital care. Enablers of integration included co-location and rotation of CCNs through urgent care settings including OAUs and EDs. This enabled nurses to develop skills, make decisions about referral to home care and gain the confidence of referring clinicians. Conclusions Integration of CCNTs at multiple points in the urgent care system is required in order to provide an alternative to

Jurassic domes in the North Sea - northern North Atlantic region

Energy Technology Data Exchange (ETDEWEB)

Surlyk, F. [Univ. of Copenhagen, Geological Inst., Copenhagen (Denmark)

1996-12-31

The stratigraphic and tectonic evolution of the Jurassic of East Greenland, the Norwegian Shelf and the North Sea is remarkably similar. A major Middle Jurassic unconformity occurs in all three areas. In the North Sea it is commonly termed the `Mid-Cimmerian Unconformity` and is characterized by progressive truncation of the underlying section towards a centre at the triple junction between the Central Graben, Viking Graben and Moray Firth. Strata above the unconformity show a progressive Late Aalenian-Early Kimmeridgian onlap in the same direction. These relations have been interpreted as caused by Early Jurassic uplift and of a major thermal dome in the central North Sea, followed by Medial and Late Jurassic rifting, erosion, deflation and transgression of the dome. The East Greenland unconformity shows progressive truncation of underlying strata from south to north, and Bajocian to Callovian onlap in the same direction. The same pattern seems to be developed on the conjugate Norwegian margin. This suggests the possibility that the three unconformities have similar causes for their development. It is proposed that major rift domes formed in the Central North Sea and in the Greenland-Norway seaway in Early Jurassic times. The domes were eroded and gradually deflated during Medial Jurassic times and were finally submerged by the Late Oxfordian-Kimmeridgian. They were associated with volcanism and rifting which was delayed with respect to dome initiation. Roughly contemperaneous domes were present west of Britain, north of the Porcupine Seabight, and in Scania, southern Sweden, as reflected by development of asymmetrical unconformities showing progressive truncation of underlying strata, onlap of overlying Jurassic strata, and associated intrusive and extrusive volcanism. The domes are related to impingement of the heads of transient mantle plumes at the base of the lithosphere. The associated unconformities are thus of non-eustatic nature. Domal uplift and

Using scenarios of North Slope energy and resource development to assess research and monitoring needs

Payne, J. F.

2016-12-01

Significant Arctic environmental and socio-economic change has been observed on the North Slope of Alaska, presenting challenges for resident communities and management agencies that need to adapt to future changes that are difficult to model or predict. Continued climate change coupled with new or modified energy development could substantially alter the landscape and ecosystem in the future. The North Slope Science Initiative (NSSI) recognized the value of using a participatory scenarios process to consider plausible future energy and resource development scenarios through the year 2040 to help identify and prioritize research and monitoring needs on the North Slope. The scenarios process engaged diverse stakeholders, including subject matter experts and local knowledge holders. Through identification and ranking of key drivers and uncertainties relevant to the focus of the study, a series of spatially explicit scenarios was developed, analyzed in terms of low, medium and high development activities. Climate change and economic factors were key drivers affecting plausible energy development scenarios. The implications from each of the scenarios were then used to identify important research and monitoring activities and their relevant spatial scales. The scenarios project identified over 40 research and monitoring needs. The top five research needs addressed data gaps and key concerns related to how the scenarios could affect: hunting and trapping on land, health and community well-being, permafrost and hydrology, marine mammal subsistence and potential marine oil spills. The use of a participatory scenarios process was essential for identifying a range of plausible energy and resource development scenarios using a framework that involved a systematic assessment of complex interacting drivers of change, consideration of key uncertainties, and transparency throughout the project.

Effective tools for retail food environments in northern and remote communities are lacking. This paper examines the challenges of conducting food environment assessments in northern and remote communities in Canada encountered during our experience with a food costing project. One of the goals of the Paying for Nutrition in the North project is to develop guidelines to improve current food costing tools for northern Canada. Paying for Nutrition illustrates the complex context of measuring food environments in northern and remote communities. Through the development of a food costing methodology guide to assess northern food environments, several contextual issues emerged, including retail store oligopolies in communities; the importance of assessing food quality; informal social food economies; and the challenge of costing the acquisition and consumption of land- and water-based foods. Food environment measures designed for northern and remote communities need to reflect the geographic context in which they are being employed and must include input from local residents.

2011-07-01

Reducing racial disparities in postdisaster mental health requires the integration of unique and complex community challenges in disaster planning. We conducted focus group discussions with 13 community leaders and 7 clinical providers in eastern North Carolina to inform the adaptation of a competency-based training model in postdisaster mental health for black communities. The audience-specific perspectives on disaster mental health and training priorities were identified by structured thematic analyses. Community leaders and clinical providers without personal ties to the local black population were unaware of internal networks and other community resources. Conversely, most black community leaders and clinical providers were unaware of local disaster response resources. All participants identified training in coordination, outreach to reduce mental health stigma, and cultural competence as priority training needs. Black community leaders also were concerned about their inclusion in local planning and leveraging resources. These inputs and suggestions made for tailoring with culturally appropriate language and processes guided the development of learning objectives, content, and field testing of the feasibility of trainer the trainer delivery of postdisaster mental health training for clinical providers and community leaders serving vulnerable black populations.

North-South precipitation patterns in western North America on interannual-to-decadal timescales

The overall amount of precipitation deposited along the West Coast and western cordillera of North America from 25??to 55??N varies from year to year, and superimposed on this domain-average variability are varying north-south contrasts on timescales from at least interannual to interdecadal. In order to better understand the north-south precipitation contrasts, their interannual and decadal variations are studied in terms of how much they affect overall precipitation amounts and how they are related to large-scale climatic patterns. Spatial empirical orthogonal functions (EOFs) and spatial moments (domain average, central latitude, and latitudinal spread) of zonally averaged precipitation anomalies along the westernmost parts of North America are analyzed, and each is correlated with global sea level pressure (SLP) and sea surface temperature series, on interannual (defined here as 3-7 yr) and decadal (>7 yr) timescales. The interannual band considered here corresponds to timescales that are particularly strong in tropical climate variations and thus is expected to contain much precipitation variability that is related to El Nino-Southern Oscillation; the decadal scale is defined so as to capture the whole range of long-term climatic variations affecting western North America. Zonal EOFs of the interannual and decadal filtered versions of the zonal-precipitation series are remarkably similar. At both timescales, two leading EOFs describe 1) a north-south seesaw of precipitation pivoting near 40??N and 2) variations in precipitation near 40??N, respectively. The amount of overall precipitation variability is only about 10% of the mean and is largely determined by precipitation variations around 40??-45??N and most consistently influenced by nearby circulation patterns; in this sense, domain-average precipitation is closely related to the second EOF. The central latitude and latitudinal spread of precipitation distributions are strongly influenced by precipitation

North by north-west: climate change and directions of density shifts in birds.

There is increasing evidence that climate change shifts species distributions towards poles and mountain tops. However, most studies are based on presence-absence data, and either abundance or the observation effort has rarely been measured. In addition, hardly any studies have investigated the direction of shifts and factors affecting them. Here, we show using count data on a 1000 km south-north gradient in Finland, that between 1970-1989 and 2000-2012, 128 bird species shifted their densities, on average, 37 km towards the north north-east. The species-specific directions of the shifts in density were significantly explained by migration behaviour and habitat type. Although the temperatures have also moved on average towards the north north-east (186 km), the species-specific directions of the shifts in density and temperature did not correlate due to high variation in density shifts. Findings highlight that climate change is unlikely the only driver of the direction of species density shifts, but species-specific characteristics and human land-use practices are also influencing the direction. Furthermore, the alarming results show that former climatic conditions in the north-west corner of Finland have already moved out of the country. This highlights the need for an international approach in research and conservation actions to mitigate the impacts of climate change. © 2015 John Wiley & Sons Ltd.

Many women do not get mammography screenings at the intervals recommended for early detection and treatment of breast cancer. The Guide to Community Preventive Services (Community Guide) recommends a range of evidence-based strategies to improve mammography rates. However, nurses and others working in community-based settings make only limited use of these strategies. We report on a dissemination intervention that partnered the University of North Carolina with the Susan G. Komen Triangle Affiliate to disseminate Community Guide breast cancer screening strategies to community organizations.

The cause of decadal climate variability over the North Pacific and North America is investigated by analyzing data from a multi-decadal integration with a state of the art coupled ocean-atmosphere model and observations. About one third of the low-frequency climate variability in the region of interest can be attributed to a cycle involving unstable air-sea interactions between the subtropical gyre circulation in the North Pacific and the Aleutian low pressure system. The existence of this cycle provides a basis for long-range climate forecasting over the western United States at decadal time scales. (orig.)

North-south interdependence

Energy Technology Data Exchange (ETDEWEB)

Norse, D

1979-01-01

The sound eco-development of agriculture can help to establish a cooperative and harmonious north-south interdependence. The interdependence pattern is seen when the major agricultural suppliers (energy, fertilizers, and pesticides) are examined in the context of commodity transfers of grain and rubber. The consumers of either the north or south would be unable to find alternative sources without major production or social disruption. The Organization of Economic Co-operation and Development (OECD) INTERFUTURES study examines the chain of dependencies between raw materials and markets and the implications for economic development, employment, and environmental hazards. If interdependence is to benefit both the north and the south, technological fixes will not be adequate or appropriate to deal with the potential hazards. (DCK)

Community-wide job loss and teenage fertility: evidence from North Carolina.

Using North Carolina data for the period 1990-2010, we estimate the effects of economic downturns on the birthrates of 15- to 19-year-olds, using county-level business closings and layoffs as a plausibly exogenous source of variation in the strength of the local economy. We find little effect of job losses on the white teen birthrate. For black teens, however, job losses to 1 % of the working-age population decrease the birthrate by around 2 %. Birth declines start five months after the job loss and then last for more than one year. Linking the timing of job losses and conceptions suggests that black teen births decline because of increased terminations and perhaps also because of changes in prepregnancy behaviors. National data on risk behaviors also provide evidence that black teens reduce sexual activity and increase contraception use in response to job losses. Job losses seven to nine months after conception do not affect teen birthrates, indicating that teens do not anticipate job losses and lending confidence that job losses are "shocks" that can be viewed as quasi-experimental variation. We also find evidence that relatively advantaged black teens disproportionately abort after job losses, implying that the average child born to a black teen in the wake of job loss is relatively more disadvantaged.

The Asian-Bering-North American teleconnection: seasonality, maintenance, and climate impact on North America

The Asian-Bering-North American (ABNA) teleconnection index is constructed from the normalized 500-hPa geopotential field by excluding the Pacific-North American pattern contribution. The ABNA pattern features a zonally elongated wavetrain originating from North Asia and flowing downstream across Bering Sea and Strait towards North America. The large-scale teleconnection is a year-round phenomenon that displays strong seasonality with the peak variability in winter. North American surface temperature and temperature extremes, including warm days and nights as well as cold days and nights, are significantly controlled by this teleconnection. The ABNA pattern has an equivalent barotropic structure in the troposphere and is supported by synoptic-scale eddy forcing in the upper troposphere. Its associated sea surface temperature anomalies exhibit a horseshoe-shaped structure in the North Pacific, most prominent in winter, which is driven by atmospheric circulation anomalies. The snow cover anomalies over the West Siberian plain and Central Siberian Plateau in autumn and spring and over southern Siberia in winter may act as a forcing influence on the ABNA pattern. The snow forcing influence in winter and spring can be traced back to the preceding season, which provides a predictability source for this teleconnection and for North American temperature variability. The ABNA associated energy budget is dominated by surface longwave radiation anomalies year-round, with the temperature anomalies supported by anomalous downward longwave radiation and damped by upward longwave radiation at the surface.

(1) To investigate the response to a serum antigen-detecting ELISA for cysticercosis and a stool coproantigen test for taeniasis in two rural communities (mountainous and coastal areas) and one group of (peri-)urban factory workers; and (2) to examine clinical features of human cysticercosis in northern Vietnam. Villagers and factory workers and their families were informed and invited to participate in the study. Blood and faecal samples were collected from the participants and a simple questionnaire on taeniasis/cysticercosis completed. Serum was examined for the presence of circulating cysticercus antigen by a monoclonal-based sandwich ELISA. Ag-ELISA positive persons underwent a clinical examination and a computed tomography (CT) scan. Stool samples were examined microscopically for the presence of Taenia eggs and for copro-antigens. Tapeworms were identified following therapeutic expulsion using morphology and PCR-RFLP. Circulating cysticercus antigens, suggesting active infection, were detected in 5.3% (16/303), 0.6% (1/175) and 0.0% (0/229) of the sampled individuals from the mountainous, coastal and urban regions, respectively. Clinical examination and CT scan of the cysticercus antigen positive persons showed that active cysticercosis did not cause severe disease in most cases. Taenia copro-antigens were found in 0.3% (1/297), 1.8% (3/166) and 0.0% (0/228) of the stool samples from the mountainous, coastal and urban communities, respectively. Three tapeworms were expelled after treatment: two Taenia solium and one Taenia saginata. This survey points to a focal distribution of taeniasis/cysticercosis and suggests that human cysticercosis is rather acquired due to close contact with a T. solium carrier and self-infection, than through infection from the environment.

Studies of environmental radioactivity in Cumbria

The physical characteristics and actinide adsorption behaviour of colloids and fine particulates in Cumbrian coastal sediments and seawater have been determined to assess the role of particles in the sea to land transfer of actinides in seaspray. Procedures have been developed for the separation of particulates into different size and mineral fractions using deflocculation and sedimentation under gravity and centrifugally. These fractions have been characterised using a range of physicochemical techniques. Specific activities of actinides (Pu, Am) adsorbed on these fractions have been correlated with size and mineral composition. Tentative evidence of the role of the fine particulates in sea to land transfer is discussed. (author)

Indigenous communities of the Thakht-e-Sulamian hills reside in the North-West tribal belt of Pakistan, where disadvantaged socio-economic frames, lack of agricultural land and food insecurity represent crucial problems to their survival. Several studies in diverse areas worldwide have pointed out the importance of wild food plants (WFPs) for assuring food sovereignty and food security, and therefore the current study was aimed at documenting traditional knowledge of WFPs and analyzing how this varies among generations. Ethnobotanical data were collected during 2010-2012. In total of seventy-two informants were interviewed in ten villages via in-depth interviews and group discussions with key informants followed by freelisting. Data were analyzed through descriptive and inferential statistics and novelty was checked by comparing the gathered data with the published literature. A total of fifty-one WFP species belonging to twenty-eight families were documented. Rosaceae was the dominant family with the largest number of species and highest frequency of citation (FC). July was the peak month for availability of WFPs, and fruit was the most commonly consumed part. Among the most cited species, Olea ferrugenia was ranked first with a FC = 1, followed by Amaranthus spinosus (FC = 0.93). Of the documented species about 14 % (7) were marketable and 27 % (14) were reported for the first time to be used as WFP species in Pakistan. WFPs still play an important role in the food and culture of the study area and the folk knowledge attached to them is remarkable in the region, although declining among the younger generations. The recorded species needs to be re-evaluated in local projects aimed at fostering endogenous strategies of food security, as well as re-evaluating cultural heritage and sustaining small-scale food market circuits.

This article explores sense of community with a group of older African women, who were forcibly relocated during apartheid. The situation of a marginalised group, with a history of disconnection from younger generations and from place, provides an opportunity to consider the relevance of community in later life. The research was conducted at a day centre for older people in the North West Province of South Africa, more than 50 years after forced relocations took place. Eleven older women (70 years and older) participated. Qualitative data were obtained through visual research methods and group discussions and were thematically analysed. Findings were that place and sense of belonging as well as elements of community were relevant. Participants reported limited connections to place in either childhood or current communities. Post relocation, a sense of belonging was expressed only in relation to a shared-interest community of peers that addressed their needs for safety, emotional support and instrumental care. Also, generational relations were strained, giving rise to a sense of loss of a community where both young and old were responsible for each other. Constrained resource communities have a profound impact on opportunities to create a sense of belonging. © 2013 The Authors.

Conventional diagnosis of malaria has relied upon either clinical diagnosis or microscopic examination of peripheral blood smears. These methods, if not carried out exactly, easily result in the over- or under-diagnosis of malaria. The reliability and accuracy of malaria RDTs, even in extremely challenging health care settings, have made them a staple in malaria control programmes. Using the setting of a pilot introduction of malaria RDTs in Greater Garissa, North Eastern Province, Kenya, this study aims to identify and understand perceptions regarding malaria diagnosis, with a particular focus on RDTs, and treatment among community members and health care workers (HCWs). The study was conducted in five districts of Garissa County. Focus group discussions (FGD) were performed with community members that were recruited from health facilities (HFs) supported by the MENTOR Initiative. In-depth interviews (IDIs) and FGDs with HCWs were also carried out. Interview transcripts were then coded and analysed for major themes. Two researchers reviewed all codes, first separately and then together, discussed the specific categories, and finally characterized, described, and agreed upon major important themes. Thirty-four FGDs were carried out with a range of two to eight participants (median of four). Of 157 community members, 103 (65.6%) were women. The majority of participants were illiterate and the highest level of education was secondary school. Some 76% of participants were of Somali ethnicity. Whilst community members and HCWs demonstrated knowledge of aspects of malaria transmission, prevention, diagnosis, and treatment, gaps and misconceptions were identified. Poor adherence to negative RDT results, unfamiliarity and distrust of RDTs, and an inconsistent RDT supply were the main challenges to become apparent in FGDs and IDIs. Gaps in knowledge or incorrect beliefs exist in Greater Garissa and have the potential to act as barriers to complete and correct malaria case

Reducing Flood Impacts for Wellbeing of Arctic Communities through Collaboration among Community and Tribal Leaders, Scientists, and Emergency Man

In Alaska and the Sakha Republic (Siberia), multiple communities are exposed to flooding every spring. A bilateral and multidisciplinary team was established, as part of the U.S. State Department FY2015-16 U.S.-Russia Peer-to-Peer Dialogue Initiative, to conduct the project Reducing Spring Flood Impacts for Wellbeing of Communities of the North. The project comprised community-based participatory research, education, and cultural activities that used flood sites in Alaska and Siberia as case studies. A diverse and bilateral team (community leaders, scientists, students, and emergency managers) was established to share experiences and identify best practices in mitigating the risk of and improving response to floods.This science-community collaboration has inspired a dialogue between present and future decision makers and community residents. Preliminary analysis revealed that community members in both regions are interested in collaborations with scientists to reduce flood risks and impacts. They are eager to share their experiences. However, scientists have to earn the trust of and develop a rapport with local leaders beforehand. Conflicts arise when communities perceive scientists as governmental representatives due to the fact that most scientific funds come from federal and state grants. Scientists are also held responsible for disasters, due to their roles in disaster forecasting and warnings. In both regions, impacted populations often blame the government for flood impacts; not unreasonably. Originally nomadic, native populations were forced to settle in floodplains by governments. Now, exposed to floods, they regard damage reimbursement as a predominantly governmental responsibility. Scientists can offer long-term solutions that would benefit communities at risk and governmental entities. However, it is important for scientists not to impose solutions, but instead initiate and maintain a dialogue about alternatives, especially as sensitive as relocation.

Riverine bacterial communities play an essential role in the biogeochemical coupling of terrestrial and marine environments, transforming elements and organic matter in their journey from land to sea. However, precisely due to the fact that rivers receive significant terrestrial input, the distinction between resident freshwater taxa vs. land-derived microbes can often become ambiguous. Furthermore, ecosystem perturbations could introduce allochthonous microbial groups and reshape riverine bacterial communities. Using full- and partial-length 16S ribosomal RNA gene sequences, we analyzed the composition of bacterial communities in the Tar River of North Carolina from November 2010 to November 2011, during which a natural perturbation occurred: the inundation of the lower reaches of an otherwise drought-stricken river associated with Hurricane Irene, which passed over eastern North Carolina in late August 2011. This event provided the opportunity to examine the microbiological, hydrological, and geochemical impacts of a disturbance, defined here as the large freshwater influx into the Tar River, superimposed on seasonal changes or other ecosystem variability independent of the hurricane. Our findings demonstrate that downstream communities are more taxonomically diverse and temporally variable than their upstream counterparts. More importantly, pre- vs. post-disturbance taxonomic comparison of the freshwater-dominant Betaproteobacteria class and the phylum Verrucomicrobia reveal a disturbance signature of previously undetected taxa of diverse origins. We use known traits of closely-related taxa to interpret the ecological function of disturbance-associated bacteria, and hypothesize that carbon cycling was enhanced post-disturbance in the Tar River, likely due to the flux of organic carbon into the system associated with the large freshwater pulse. Our analyses demonstrate the importance of geochemical and hydrological alterations in structuring bacterial communities

Full Text Available Abstract Background In the present study we have investigated the cultural transmission of two types of traditional plant knowledge in two communities of North-western Patagonia, Argentina. In the Pilcaniyeu community, we studied the transmission of traditional knowledge related to horticultural practices in home-gardens, greenhouses and gardens; while in the community of Cuyin Manzano, we studied wild plant gathering customs. Methods Ethnobotanical fieldwork was conducted by means of semi-structured interviews, in which we investigated which plants are used, at what life history phase was learned, modes of transmission and who the principal transmitters were in childhood and adulthood. In both communities, each of this three aspects related to cultural transmission were categorized and the frequencies of each category were obtained. The total number of species recorded in each community was also calculated. Frequencies were analyzed with the Chi-square test of independence. Results and discussion In both communities, transmission of traditional plant knowledge begins at an early age, as a family custom, in which women play a predominant role. Wild plant use and horticultural knowledge continue to be learned during adulthood. This was particularly registered associated with horticultural learning, which receives greater influence from extension agents who are introducing new practices and technology. This outside influence, which implies novelty, could imply syncretism but also traditional knowledge loss. Conclusion Given the remarkable acculturation processes occurring at present in rural communities of Northwestern Patagonia, it might be of vital importance to document traditional knowledge of ancient practices. Moreover, it could be interesting to share our results with both populations in order to encourage participatory activities within the communities which could enhance traditional knowledge horizontal transmission, particularly among

The prevalence of chronic liver disease (CLD) in the Aboriginal North American population is disproportionately higher than that of the non-indigenous population. Hepatitis C virus (HCV) is the second leading cause of CLD in American Indians or Alaska Natives (AIANs). This study described the experience of two teaching community medical centers in North Dakota in treating HCV infection among AIANs and compared treatment outcomes to a cohort of Caucasian patients. The retrospective study described the characteristics and proportion of AIAN patients with HCV who received treatment. Documented reasons for not receiving treatment were analyzed. For those AIAN patients treated for HCV infection, responses to treatment, including rapid, early and sustained virological responses (SVRs), were compared with those of Caucasians. Only 22 (18%) of 124 AIANs with HCV infection received treatment. Common reasons for not receiving treatment include lack of access to specialists, concomitant or decompensated liver disease, alcohol and drug abuse and cost. There were no significant differences in the baseline characteristics and key predictors of SVR in AIANs compared to Caucasian controls. Most AIAN patients with HCV infection do not receive treatment despite comparable treatment response rates to Caucasians. Further population-based studies, addressing access to specialized hepatitis C treatment and public health concerns are warranted, as it is crucial to treat chronic HCV infection to decrease the burden of disease in the AIAN community.

Full Text Available Current challenges to coral reef sustainability include overfishing, destructive fishing practices, bleaching, acidification, sea-level rise, starfish, algae, agricultural run-off, coastal and resort development, pollution, diseases, invasive species and hurricanes. We used SCUBA belt transects to record coral cover and digital image analysis in the Dairy Bull Reef off the north coast of Jamaica and found that it is a positive example of how reefs can recover after major environmental disturbance. Live coral cover increased from 13±5% in 2006 to 31±7% in 2008, while live Acropora cervicornis increased from 2±2% in 2006 to 22±7% in 2008. Coral cover levels were maintained until 2012.
