    Residents of areas with lower socioeconomic status (SES) are known to be less physically active during leisure time. Neighborhood walkability has been shown to be related to recreational walking equally in low and high SES areas. This cross-sectional study tested whether associations of specific environmental attributes, measured objectively and subjectively, with walking for recreation were moderated by area-level SES. The data of the North West Adelaide Health Study collected in 2007 (n = 1...

    Full Text Available This study examines the relationships between area-level socioeconomic position (SEP and the prevalence and trajectories of metabolic syndrome (MetS and the count of its constituents (i.e., disturbed glucose and insulin metabolism, abdominal obesity, dyslipidemia, and hypertension. A cohort of 4,056 men and women aged 18+ living in Adelaide, Australia was established in 2000–2003. MetS was ascertained at baseline, four and eight years via clinical examinations. Baseline area-level median household income, percentage of residents with a high school education, and unemployment rate were derived from the 2001 population Census. Three-level random-intercepts logistic and Poisson regression models were performed to estimate the standardized odds ratio (SOR, prevalence risk ratio (SRR, ratio of SORs/SRRs, and (95% confidence interval (CI. Interaction between area- and individual-level SEP variables was also tested. The odds of having MetS and the count of its constituents increased over time. This increase did not vary according to baseline area-level SEP (ratios of SORs/SRRs ≈ 1; p ≥ 0.42. However, at baseline, after adjustment for individual SEP and health behaviours, median household income (inversely and unemployment rate (positively were significantly associated with MetS prevalence (SOR (95%CI = 0.76 (0.63–0.90, and 1.48 (1.26–1.74, respectively, and the count of its constituents (SRR (95%CI = 0.96 (0.93–0.99, and 1.06 (1.04–1.09, respectively. The inverse association with area-level education was statistically significant only in participants with less than post high school education (SOR (95%CI = 0.58 (0.45–0.73, and SRR (95%CI = 0.91 (0.88–0.94. Area-level SEP does not predict an elevated trajectory to developing MetS or an elevated count of its constituents. However, at baseline, area-level SEP was inversely associated with prevalence of MetS and the count of its constituents, with the association of area-level education

    Area-level socioeconomic status (SES) measures have been used as a proxy in child health research when individual SES measures are lacking, yet little is known about their validity in an urban setting. We assessed agreement between census block-group and individual-level SES measures obtained from a caregiver telephone survey in Jackson County, Missouri. Associations with prevalence of childhood overweight (OW), low birth weight (LBW), and household smoking exposure were examined using logistic regression models. Seven hundred eighty-one households were surveyed: 49% male, 76% White, mean child age 9.4 years. We found misclassification rates of 20-35% between individual vs. area-level measures of education and income; Kappa indices ranged from 0.26-0.36 indicating poor agreement. Both SES measures showed an inverse association with LBW and smoking exposure. Area-level SES measures may reflect a construct inclusive of neighborhood resources; routine substitution of these measures should be interpreted with caution, despite similar correlations with health outcomes.

    Background Overweight and obesity lead to higher probability of individuals accessing primary care but adiposity estimates are rarely available at regional levels to inform health service planning. This paper analyses a large, community-derived clinical database of objectively measured body mass index (BMI) to explore relationships with area-level socioeconomic disadvantage for informing regional level planning activities. Materials and Methods The study included 91776 adults who had BMI objectively measured between 1 July 2009 and 30 June 2011 by a single pathology provider. Demographic data and BMI were extracted and matched to 2006 national census socioeconomic data using geocoding. Adjusted odds-ratios for overweight and obesity were calculated using sex-stratified logistic regression models with socioeconomic disadvantage of census collection district of residence as the independent variable. Results The prevalence of overweight or obesity was 79.2% (males) and 65.8% (females); increased with age to 74 years; and was higher in rural (74%) versus urban areas (71.4%) (p<0.001). Increasing socioeconomic disadvantage was associated with increasing prevalence of overweight (p<0.0001), obesity (p<0.0001) and overweight or obesity (p<0.0001) in women and obesity (p<0.0001) in men. Socioeconomic disadvantage was unrelated to overweight (p = 0.2024) and overweight or obesity (p = 0.4896) in males. Conclusion It is feasible to link routinely-collected clinical data, representative of a discrete population, with geographic distribution of disadvantage, and to obtain meaningful area-level information useful for targeting interventions to improve population health. Our results demonstrate novel area-level socioeconomic gradients in overweight and obesity relevant to regional health service planning. PMID:26317861

    The aim of the study is to determine the influence of area-level socio-economic status and healthcare access in addition to tumor hormone-receptor subtype on individual breast cancer stage, treatment, and mortality among Non-Hispanic (NH)-Black, NH-White, and Hispanic US adults. Analysis was based on 456,217 breast cancer patients in the SEER database from 2000 to 2010. Multilevel and multivariable-adjusted logistic and Cox proportional hazards regression analysis was conducted to account for clustering by SEER registry of diagnosis. NH-Black women had greater area-level access to healthcare resources compared with women of other races. For instance, the average numbers of oncology hospitals per million population in counties with NH-Black, NH-White, and Hispanic women were 8.1, 7.7, and 5.0 respectively; average numbers of medical doctors per million in counties with NH-Black, NH-White, and Hispanic women were 100.7, 854.0, and 866.3 respectively; and average number of Ob/Gyn in counties with NH-Black, NH-White, and Hispanic women was 155.6, 127.4, and 127.3, respectively (all p values cancer mortality compared with NH-White women even after adjusting for hormone-receptor subtype, area-level socioeconomic status, and area-level healthcare access. In addition, lower county-level socio-economic status and healthcare access measures were significantly and independently associated with stage at presentation, surgery, and radiation treatment as well as mortality after adjusting for age, race/ethnicity, and HR subtype. Although breast cancer HR subtype is a strong, important, and consistent predictor of breast cancer outcomes, we still observed significant and independent influences of area-level SES and HCA on breast cancer outcomes that deserve further study and may be critical to eliminating breast cancer outcome disparities.

    2015-12-01

    International case studies of protected area performance increasingly report that conservation and socio-economic outcomes are interdependent. Effective conservation requires support and cooperation from local governments and communities, which in turn requires that protected areas contribute to the economic well-being of the communities in which they are sited. Despite increasing recognition of their importance, robust studies that document the socio-economic impacts of protected areas are rare, especially in the developed world context. We proposed 3 potential pathways through which protected areas might benefit local communities in the developed world: the improved local housing value, local business stimulus, and increased local funding pathways. We examined these pathways by undertaking a statistical longitudinal analysis of 110 regional and rural communities covering an area of approximately 600,000 km(2) in southeastern Australia. We compared trends in 10 socio-economic indicators describing employment, income, housing, business development and local government revenue from 2000 to 2010. New protected areas acquisitions led to an increased number of new dwelling approvals and associated developer contributions, increased local business numbers, and increased local government revenue from user-pays services and grants. Longer-term effects of established protected areas included increased local council revenue from a variety of sources. Our findings provide support for each of our 3 proposed benefit pathways and contribute new insights into the cycling of benefits from protected areas through the economy over time. The business and legislative models in our study are typical of those operating in many other developed countries; thus, the benefit pathways reported in our study are likely to be generalizable. By identifying and communicating socio-economic benefits from terrestrial protected areas in a developed world context, our findings represent an important

    This study assesses the interactions between sex, socioeconomic level, and children's cognitive performance. Cognitive performance was measured for a sample of 453 Portuguese children, aged between 4 and 10 years, with 218 boys and 235 girls; verbal and nonverbal cognitive ability and intelligence quotient were measured by the Cognitive Skills Scale for Children. Multivariate analysis of variance assessed the effects of sex and family's socioeconomic level on intelligence quotient. A statistically significant interaction between sex and socioeconomic level was observed for nonverbal intelligence quotient, total intelligence quotient, and two subtests. Socioeconomic level had more influence than sex on most of the cognitive tests. PMID:27154374

It is based on characteristics of changes in the number of people living in the countryside on the background of the tendencies of employment in agriculture, as well as of rural areas unemployment specificity. The author tended to verify the thesis that multifunctional development of rural areas is one of directions towards unemployment diminishing. On the other hand, it was concluded that important barriers for such a solution are both infrastructure underdevelopment and low level of professional skills of rural society. It was pointed out that a great chance for positive socioeconomic changes of the countryside is rational use of financial sources available after Poland’s EU accession.

    Nature-based tourism has the potential to enhance global biodiversity conservation by providing alternative livelihood strategies for local people, which may alleviate poverty in and around protected areas. Despite the popularity of the concept of nature-based tourism as an integrated conservation and development tool, empirical research on its actual socioeconomic benefits, on the distributional pattern of these benefits, and on its direct driving factors is lacking, because relevant long-term data are rarely available. In a multi-year study in Wolong Nature Reserve, China, we followed a representative sample of 220 local households from 1999 to 2007 to investigate the diverse benefits that these households received from recent development of nature-based tourism in the area. Within eight years, the number of households directly participating in tourism activities increased from nine to sixty. In addition, about two-thirds of the other households received indirect financial benefits from tourism. We constructed an empirical household economic model to identify the factors that led to household-level participation in tourism. The results reveal the effects of local households' livelihood assets (i.e., financial, human, natural, physical, and social capitals) on the likelihood to participate directly in tourism. In general, households with greater financial (e.g., income), physical (e.g., access to key tourism sites), human (e.g., education), and social (e.g., kinship with local government officials) capitals and less natural capital (e.g., cropland) were more likely to participate in tourism activities. We found that residents in households participating in tourism tended to perceive more non-financial benefits in addition to more negative environmental impacts of tourism compared with households not participating in tourism. These findings suggest that socioeconomic impact analysis and change monitoring should be included in nature-based tourism management systems

    Full Text Available Being a highly industrialized country with one of the highest male lung cancer mortality rates in Europe, Belgium is an interesting study area for lung cancer research. This study investigates geographical patterns in lung cancer mortality in Belgium. More specifically it probes into the contribution of individual as well as area-level characteristics to (sub-district patterns in lung cancer mortality. Data from the 2001 census linked to register data from 2001-2011 are used, selecting all Belgian inhabitants aged 65+ at time of the census. Individual characteristics include education, housing status and home ownership. Urbanicity, unemployment rate, the percentage employed in mining and the percentage employed in other high-risk industries are included as sub-district characteristics. Regional variation in lung cancer mortality at sub-district level is estimated using directly age-standardized mortality rates. The association between lung cancer mortality and individual and area characteristics, and their impact on the variation of sub-district level is estimated using multilevel Poisson models. Significant sub-district variations in lung cancer mortality are observed. Individual characteristics explain a small share of this variation, while a large share is explained by sub-district characteristics. Individuals with a low socioeconomic status experience a higher lung cancer mortality risk. Among women, an association with lung cancer mortality is found for the sub-district characteristics urbanicity and unemployment rate, while for men lung cancer mortality was associated with the percentage employed in mining. Not just individual characteristics, but also area characteristics are thus important determinants of (regional differences in lung cancer mortality.

    Full Text Available Abstract Background Little is known about small-area variation in healthy longevity of older people and its socioeconomic correlates. This study aimed to estimate health expectancy at 65 years (HE65 at the municipal level in Japan, and to examine its relation to area socio-demographic conditions. Methods HE65 of municipalities (N = 3361 across Japan was estimated by a linear regression formula with life expectancy at 65 years and the prevalence of those certificated as needing nursing care. The relation between HE65 and area socio-demographic indicators was examined using correlation coefficients. Results The estimated HE65 (years ranged from 13.13 to 17.39 for men and from 14.84 to 20.53 for women. HE65 was significantly positively correlated with the proportion of elderly and per capita income, and negatively correlated with the percentage of households of a single elderly person, divorce rate, and unemployment rate. These relations were stronger in large municipalities (with a population of more than 100,000 than in small and medium-size municipalities. Conclusion A decrease in healthy longevity of older people was associated with a higher percentage of households of a single elderly person and divorce rate, and lower socioeconomic conditions. This study suggests that older people in urban areas are susceptible to socio-demographic factors, and a social support network for older people living in socioeconomically disadvantaged conditions should be encouraged.

  7. Assessing the Impact of Socioeconomic Variables on Small Area Variations in Suicide Outcomes in England

    Directory of Open Access Journals (Sweden)

    Peter Congdon

    2012-12-01

    Full Text Available Ecological studies of suicide and self-harm have established the importance of area variables (e.g., deprivation, social fragmentation in explaining variations in suicide risk. However, there are likely to be unobserved influences on risk, typically spatially clustered, which can be modeled as random effects. Regression impacts may be biased if no account is taken of spatially structured influences on risk. Furthermore a default assumption of linear effects of area variables may also misstate or understate their impact. This paper considers variations in suicide outcomes for small areas across England, and investigates the impact on them of area socio-economic variables, while also investigating potential nonlinearity in their impact and allowing for spatially clustered unobserved factors. The outcomes are self-harm hospitalisations and suicide mortality over 6,781 Middle Level Super Output Areas.

    Previous studies showing a geographical association between radon and various cancers, particularly the leukaemias and lymphomas, appear to be confounded by the role of radon levels as a surrogate for socioeconomic status. Higher socioeconomic status (at least at the UK county level) is correlated with higher levels of domestic radon. Controlling for the relationship between socioeconomic status and radon removes the correlation between radon exposure and lymphoproliferative disease. Reported associations between radon and lymphoproliferative disease (and possibly other cancers) may be secondary to socioeconomic variables. (author).

    Full Text Available Hydrological risk phenomena such as floods are among the most costly natural disasters worldwide, effects consisting of socioeconomic damages and deaths. The Bâsca Chiojdului catchment area, by its morphometric and hydrographic peculiarities, is prone to generate these hydrological risk phenomena, so there is a high vulnerability in the socioeconomic elements. This paper is focused on the identification of the main socioeconomic elements vulnerable to hydrological risk phenomena such as floods, based on the assessment of their manifestation potential. Thus, following the delimitation of areas with the highest flood occurrence potential (susceptibility to floods, major socioeconomic factors existing in the basin, considering human settlements (constructions, transport infrastructure, and agricultural areas (the most important category, were superimposed. Results showed a high vulnerability for all three exposed socioeconomic elements especially in valley sectors, of which household structures were the most vulnerable, given both their importance and the high number of areas highly exposed to floods (approximately 2,500 houses and outbuildings, out of a total of about 10,250, intersect the most susceptible area to floods in the study area.

    Full Text Available There has been a change in the urban-rural relations in recent decades, as a result of increased mobility and intensity of information flow, changes in the production processes and the growing globalization of markets. The old urban-rural division lost its importance for the new ones: the metropolitan areas and those beside metropolitan. This can lead to the end of the traditional urban-rural relations, some signs are already seen. This is already observed in the process of “growing” the cities with their territories to rural areas. The risk of loss of the relationship between urban and rural areas is high because of the growing disproportion between these areas and decreased territorial cohesion. It requires strengthening new and deliberate efforts in regional policy, those that are not “fighting with windmills”, ie will take into account the objective processes already taking place. The purpose of this paper is an attempt to characterise the development of economic and social processes in rural areas and proposals for further action in the context of sustainable development.

    This study aimed to identify some socioeconomic factors affecting local people in central Riyadh area for the utilization of wood and other energy sources in cooking and heating in order to develop some recommendations for conserving woodlands. The study results revealed that gas is the most common energy source used for cooking with a mean usage level of 2.79 (SD = 0.58). On the other hand, wood ranked first for heating with the highest mean, usage level of 1.90 (SD = 1.06). However, electricity and gas as sources of energy for heating ranked second and third with mean usage level of 1.81 and 0.80 respectively. The study revealed that local people with the university education were significantly making higher use of electricity for both cooking and heating and those with no formal education ranked the highest on wood use for both cooking and heating. In addition, those living in traditional houses significantly used more wood for cooking than those living in villas and apartments. Also, local people with high income levels significantly were using more electricity for heating than others. The study recommended conducting extension and environmental awareness raising programs to enhance local residents' adoption of wood substitutes, promoting employment opportunities for unemployed locals, and subsidizing prices of alternative energy sources.

    2010-06-01

    In order to provide equitable access to hospice at home palliative care services, it is important to identify the socio-economic factors associated with poorer access. In this population-based study we aimed to test the inverse care law by exploring how socio-economic status and other key demographic indicators were associated with referral rates in two distinct areas (Salford and Trafford) served by the same service. Secondary data from the UK National Census 2001, North West Cancer Intelligence Service (2004) and hospice at home service referral data (2004-06) was collated for both areas. Descriptive analysis profiled electoral ward characteristics whilst simple correlations and regression modelling estimated associations with referral rates. Referral rates were lower and cancer mortality higher in the most deprived areas (Salford). Referral rates were significantly associated with deprivation, particularly multiple deprivation, but not significantly associated with cancer mortality (service model and resources available were held constant). At the population level, the socio-economic characteristics of those referred to hospice at home rather than service provision strongly predicted referral rates. This has implications for the allocation and targeting of resources and contributes important findings to future work exploring equitable access at organizational and professional levels.

    Using the 'indirect' demographic estimation technique, levels of child mortality for some selected socioeconomic characteristics of mothers in Ilorin, an urban community in Nigeria, were derived. The adjusted effects of these variables on child mortality were assessed. The variables found to exert significant independent effects on child mortality included the husbands education, area of residence in the town, the parity of the mother, her use of modern contraception, availability of indoor pipe-borne water and the use of a refrigerator by the household. Reliable or useful information on child mortality in this part of Nigeria is hard to come by, hence, the estimates provided here can serve as useful baseline data for evaluating the impacts of child survival activities that are currently going on in that part of the country.

    Full Text Available Abstract Background This study describes the patterns and socioeconomic influences of tobacco use among adults in tobacco-cultivating regions of rural southwest China. Methods A cross-sectional survey was conducted in 8681 adults aged ≥18 years in rural areas of Yunnan Province, China from 2010 to 2011. A standardized questionnaire was administered to obtain data about participants’ demographic characteristics, individual socioeconomic status, ethnicity, self-reported smoking habits, and exposure to secondhand smoke (SHS. The socioeconomic predictors of current smoking, nicotine addiction, and SHS exposure were analyzed using multivariate logistic regression. Results The prevalence rates of tobacco use were much higher in men compared with women (current smoking 68.5% vs. 1.3%; and nicotine dependence 85.2% vs. 72.7%. However, the rate of SHS exposure was higher in women compared with men (76.6% vs. 70.5%. Tobacco farmers had higher prevalence rates of current smoking, nicotine dependence, and SHS exposure compared with participants not engaged in tobacco farming (P Conclusions This study suggests that tobacco control efforts in rural southwest China must be tailored to address tobacco-cultivating status and socioeconomic factors.

    This paper argues that migration is better defined as an adaptive response to socio-economic, cultural, political and environmental transformations, in most instances closely linked to the need to diversify income sources and reduce dependency on natural resources. Drawing on case studies in Bolivia, Senegal and Tanzania, it describes how environmental change at the local level interacts with other factors to shape migration patterns, and how such patterns in turn affect the livelihoods and resilience of individuals, households and communities in areas experiencing the impacts of climate change in the form of desertification, soil degradation, disrupted rainfall patterns and changes in temperature.

    2015-11-01

    Several global strategies for protected area (PA) expansion have been proposed to achieve the Convention on Biological Diversity's Aichi target 11 as a means to stem biodiversity loss, as required by the Aichi target 12. However, habitat loss outside PAs will continue to affect habitats and species, and PAs may displace human activities into areas that might be even more important for species persistence. Here we measure the expected contribution of PA expansion strategies to Aichi target 12 by estimating the extent of suitable habitat available for all terrestrial mammals, with and without additional protection (the latter giving the counterfactual outcome), under different socio-economic scenarios and consequent land-use change to 2020. We found that expanding PAs to achieve representation targets for ecoregions under a Business-as-usual socio-economic scenario will result in a worse prognosis than doing nothing for more than 50% of the world's terrestrial mammals. By contrast, targeting protection towards threatened species can increase the suitable habitat available to over 60% of terrestrial mammals. Even in the absence of additional protection, an alternative socio-economic scenario, adopting progressive changes in human consumption, leads to positive outcomes for mammals globally and to the largest improvements for wide-ranging species.

    Full Text Available During the past decade, the role of the built environment on physical activity has been well investigated by public health, transportation and urban design scholars and it has been shown that different aspects of the built environment can influence physical activity Public open spaces (POS like parks have many health benefits and they can be important settings and destinations for having physical activity. Inequality in access to POS which may influence the amount of physical activity can be a reason for lower physical activity among deprived neighbourhoods. This paper aims to examine whether objective access to public open spaces (POS like parks is equally across the different socio-economic status (SES areas in the City of Melbourne. Objective access to POS was measured in network distance using geographic information systems (GIS and area SES was obtained using the SEIFA (Socio-Economic Indexes for Areas index. The results showed there was a significant difference in access to POS according to the SES areas. There was a significant negative correlation between the access to POS and the SES areas in which lower SES areas had poorer access to POS in comparison with the higher ones.

    Full Text Available Introduction: Socioeconomical status may indirectly affect the obesity prevalence. This study gathers together dietary behaviour, physical activity and sedentary lifestyle in relation to the family socioeconomic status in a sample of Spanish children. Design: Population-based cross-sectional study of 3-16 years children. Methods: Questionnaires about dietary behaviors, physical activity and sedentary lifestyles, and direct anthropometric measures. Criteria of physical activity recommended was > 5METs (metabolic equivalence during 60 min/day, and sedentary lifestyle as 120 min/day of sedentary activities, using obesity criteria from the ENKID study. We derived a single "family socioeconomic level" indicator (FSEL from the level of studies, professional category and work situation of both parents. Results: 1620 children were studied. 59.5% met the physical activity recommendations. Boys with the higher FSEL quartile tend to do more physical activity. In girls, physical activity increases with the age and degree of overweight. 57.7% of boys and 48.1% of girls were found to be sedentary, with a lower rate in families with higher FSEL. Higher FSEL quartile was related to healthy dietary habits such as having breakfast, 5 meals per day and less snacking. The FSEL was related also to the consumption of whole grains, dairy products and fruits, but not to vegetables, meat or fish. The greatest risk of excess weight was found in girls > 6 years old, with a low FSEL, sedentary habits, that snack frequently and eat few proteins. Discussion: Family socioeconomic status seems to determine the level of physical activity, sedentary lifestyle and dietary behavior. The elaboration of a simple socioeconomic indicator may be useful to study factors involved in child obesity.

    formulation and adoption of the 'Township Electrification Program' followed a 'centralized and closed top-down' approach within China's communist political framework conditions, which ultimately resulted in pursuing political leaders' conceptions instead of the energy needs of local people. Third, the implementation of the Program possessed a technical orientation (e.g. construction of stations, installation of systems), and underestimated the financial implications (e.g. electricity tariff, households' ability to pay electricity fee, financial management) as well as human resources available (e.g. training for operators, household participation) and institutional capacity building (e.g. good governance, regulatory framework) at the local level. Fourth, there was a change of households' energy use pattern from traditional energy sources (such as candles and dry cell batteries) to electricity from solar PV power stations in the two investigated townships. But traditional energy sources were not totally substituted by electricity. This is due to the fact that the current electricity supply was not sufficient for households' needs and electricity was not provided daily on a regular basis. Households still had to rely on traditional energy sources. Fifth, the impacts of the Program on the improvement of socio-economic benefits for households, the improvement of township development, and the reduction of negative environmental impacts were limited. Lastly, based on these findings, this study suggests policy recommendations for the Chinese government as well as policy implications for developing countries. (orig.)

    Full Text Available The effects of stroke on stroke survivors are profound and affecttheir quality of life. The aim of this study was to establish the experience of peopleliving with stroke in low socioeconomic urban and rural areas of South Africa.A qualitative study using semi-structured interviews was used to collect data.Participants were identified from stroke registers and recruited from PHC clinicsin Soweto, Gauteng and Limpopo provinces. Participants had to have had a stroke,be above the age of 18 and had lived in the community six months to a year followingtheir stroke. The researcher or research assistant conducted the interviews ofparticipants who had had strokes as well as their caregivers in the home language of the participants. The interviewswere audio taped, transcribed and translated into English. A thematic content analysis was done.Thirty two participants were interviewed, 13 from Soweto, Gauteng, and 19 from rural Limpopo provinces. Theresults suggest that the sudden, overwhelming transformation as a result of a stroke forms a background for loss ofcommunity mobility, social isolation, role reversal within the family and community, loss of role within the family andcommunity, loss of meaningful activities of daily living, loss of hope and threat to livelihood amongst stroke survivorsliving in low socioeconomic areas of South Africa.An overwhelming picture of despondency was found, with few positive stories told in both settings. The themesidentified from the interviews reflected the experience and issues that a patient with stroke has to deal with in lowsocioeconomic areas of South Africa.

The data on the prevalence of parasites with respect to sex and age showed that the females harbored more numbers of parasites when compared to males. Further, with respect to age, children and teenagers had surplus parasites compared to old age groups. The percentage of educational status showed a reduction in the number of parasites in the higher education dwellers. These parasites could be prevented by possible grouping of better ecological design and hygiene. Conclusively, the examination of personal hygiene as well as routine medical examination and treatment is strongly recommended in the low socio-economic areas.

    Based on the current literature, this paper is mainly intended to test whether environmental factors and socio-economic factors will have direct effect on the longevity at county level in China in order to determine the major determinants affecting local longevity level. Using the multi-regression model,we find the result that factors such as temperature,climate, longitude, type of soils, as well as type of agricultural food production play a major role in shaping the longevity at county level, and that socioeconomic factors like infant mortality and gross death rate also have some direct impact on longevity, but the degree of impact is not as strong as the above environmental factors.

  2. Using GIS to develop socio-economic profiles of areas adjacent to DOE facilities

    International Nuclear Information System (INIS)

    The objective of the research addressed in this paper is to identify and analyze the offsite effects of DOE activities at the Savannah River Site. The paper presents the socio-economic conditions of the areas surrounding the site in order to evaluate the possible effects of DOE activities. The study employed a geographic information system (GIS) in order to evaluate spatial relationships between otherwise unrelated factors. Socio-economic data used in the study are publicly available and were obtained mainly from the Bureau of the Census. The Department of Energy (DOE), currently dealing with the environmental management of a large number of sites throughout the United States, must consider the effects of its activities on surrounding populations and ensure compliance with the various federal regulations, such as the executive order on environmental justice. Environmental justice is the process of studying and achieving equal distribution of the effects of environmental pollution on populations across social and economic lines. An executive order signed by the President has directed federal agencies, including the Department of Energy, to make achieving environmental justice a part of the agency's mission by identifying and addressing disproportionately high and adverse human health or environmental effects of its programs, policies, and activities on minority and low-income populations

    Full Text Available INTRODUCTION: The epidemiological transition has resulted in a major increase in the prevalence of obesity in North Africa. This study investigated differences in obesity and its association with area of residence, gender and socio-economic position among adults in Algeria and Tunisia, two countries with socio-economic and socio-cultural similarities. METHODS: Cross-sectional studies used stratified, three-level, clustered samples of 35-70 year old adults in Algeria, (women n = 2741, men n = 2004 and Tunisia (women n = 2964, men n = 2379. Thinness was defined as Body Mass Index (BMI = weight/height <18.5 kg/m(2, obesity as BMI ≥30, and abdominal obesity as waist circumference/height ≥0.6. Associations with area of residence, gender, age, education, profession and household welfare were assessed. RESULTS: Prevalence of thinness was very low except among men in Algeria (7.3% C.I.[5.9-8.7]. Prevalence of obesity among women was high in Algeria (30.1% C.I.[27.8-32.4] and Tunisia (37.0% C.I.[34.4-39.6]. It was less so among men (9.1% C.I.[7.1-11.0] and 13.3% C.I.[11.2-15.4].The results were similar for abdominal obesity. In both countries women were much more obesity-prone than men: the women versus men obesity Odds-Ratio was 4.3 C.I.[3.4-5.5] in Algeria and 3.8 C.I.[3.1-4.7] in Tunisia. Obesity was more prevalent in urban versus rural areas in Tunisia, but not in Algeria (e.g. for women, urban versus rural Odds-Ratio was 2.4 C.I.[1.9-3.1] in Tunisia and only 1.2 C.I.[1.0-5.5] in Algeria. Obesity increased with household welfare, but more markedly in Tunisia, especially among women. Nevertheless, in both countries, even in the lowest quintile of welfare, a fifth of the women were obese. CONCLUSION: The prevention of obesity, especially in women, is a public health issue in both countries, but there were differences in the patterning of obesity according to area of residence and socio-economic position. These specificities must

    Full Text Available Abstract Background Smoking during pregnancy has been associated with socioeconomic determinants and it is recognized as the most important preventable risk factor for an unsuccessful pregnancy outcome. Turkey has national data on the prevalance of smoking during pregnancy; however there is no data on the characteristics of the high-risk population. This is a field study that aims to identify socioeconomic determinants for smoking during pregnancy as well as differentiating the daily and occasional smokers. Method Cross sectional study was conducted among women with 0-5 year old children living in the area served by Primary Health Care Center (PHCC in Burhaniye, Turkey. Face-to-face interviews were conducted by the researchers during January-March 2008 at the home of the participants with 83.7% response rate (n = 256. The relation of "smoking during pregnacy" and "daily smoking during pregnancy" with the independent variables was determined with χ2 tests. Women's age, educational level, number of previous births, place of origin, migration, partner's educational level, poverty, perceived income, social class were evaluated. Statistical significance was achieved when the p value was less than 0.05. The variables in relation with the dependent variables in the χ2 tests were included in the forward-stepwise logistic analysis. Results Prevalance of smoking during pregnancy was 22.7%. The majority (74.1% were daily smokers. Young mothers ( Conclusions Systematic attention should be paid to socioeconomic determinants in smoking for pregnant women, especially in countries like Turkey with high rates of infant and mother mortality and substantial health inequalities.

    Objective The aim of this review is to identify and understand the contexts that effect access to high-quality primary care for socioeconomically disadvantaged older people in rural areas. Design A realist review. Data sources MEDLINE and EMBASE electronic databases and grey literature (from inception to December 2014). Eligibility criteria for selecting studies Broad inclusion criteria were used to allow articles which were not specific, but might be relevant to the population of interest to be considered. Studies meeting the inclusion criteria were assessed for rigour and relevance and coded for concepts relating to context, mechanism or outcome. Analysis An overarching patient pathway was generated and used as the basis to explore contexts, causal mechanisms and outcomes. Results 162 articles were included. Most were from the USA or the UK, cross-sectional in design and presented subgroup data by age, rurality or deprivation. From these studies, a patient pathway was generated which included 7 steps (problem identified, decision to seek help, actively seek help, obtain appointment, get to appointment, primary care interaction and outcome). Important contexts were stoicism, education status, expectations of ageing, financial resources, understanding the healthcare system, access to suitable transport, capacity within practice, the booking system and experience of healthcare. Prominent causal mechanisms were health literacy, perceived convenience, patient empowerment and responsiveness of the practice. Conclusions Socioeconomically disadvantaged older people in rural areas face personal, community and healthcare barriers that limit their access to primary care. Initiatives should be targeted at local contextual factors to help individuals recognise problems, feel welcome, navigate the healthcare system, book appointments easily, access appropriate transport and have sufficient time with professional staff to improve their experience of healthcare; all of which

  8. Assessing the state-level consequences of global warming: Socio-economic and energy demand impacts

    International Nuclear Information System (INIS)

    The large body of research on climate change has begun to recognize a significant deficiency: the lack of analysis of the impact of climate change at a spatial level consistent with the anticipated occurrence of climate change. Climate change is likely to vary by region, while impact analysis has focused on much larger political units. Clearly, adaptation/mitigation strategies must be developed at a level consistent with political and policy-making processes. This paper specifically addresses this deficiency by identifying the potential socio-economic and energy demand consequences of climate change for subnational regions. This is accomplished via the development and application of a regional simultaneous equation, econometric simulation model that focuses on five states (Illinois, Indiana, Michigan, Ohio, and Wisconsin) in the Great Lakes region of the US. This paper presents a process for obtaining state-specific assessments of the consequences of climate change for the socio-economic system. As such, it provides an indication of which economic sectors are most sensitive to climate change for a specific state (Indiana), a set of initial mitigation/adaptation strategies for this state, and the results of testing these strategies in the policy analysis framework enabled by the model. In addition, the research demonstrates an effective methodology for assessing impacts and policy implications of climate change at a level consistent with policy making authority

    Full Text Available Background Hyperphosphoremia is one of the most important risk factors for morbidity and mortality for chronic kidney disease (CKD patients, and also, for the general population. Excessive dietary intake of phosphate (P is one of the key factors. In particular, P in its inorganic form, which is contained in food additives, is more readily absorbed. Unfortunately, these food additives are mostly present in convenience so called “fast foods” (pre-cooked, soft drinks, which represent the typical food consumed by our hemodialysis (HD population, composed by elderly people, mostly low-socio economic class, who often live alone. Objectives We performed an observational retrospective multicenter study to find any association between social, cultural and economic situation, as well as food habits, and P levels in a cohort of patients on HD. Secondarily; we also examined the association between the fast food consumption and increased P levels, as well as patient compliance for P binding products. Patients and Methods To explore the association between socio-economic factors and serum P levels, we enrolled 100 patients on periodic HD treatment from three different units. Information on social, cultural, economic, diet habits, therapy for hyperphosphoremia and hematological and clinical parameters had been collected through specific questionnaires, administered by a physician. Results Results showed serum P level was reduced in patients who live alone compared to patients in family (P = 0.04, in self-sufficient (P = 0.05 and in patients belonging to middle-upper class, versus low-class (P = 0.003. Fast foods intake correlates with increase in P serum levels (P = 0.002, whilst the same correlation was not found for cheese intake. Our data show that socio-economic status and food habits are useful predictors of P serum levels. Conclusions In conclusion, dietary counseling of patients on HD is mandatory.

    Full Text Available Objective: This study aimed to determine the prevalence of food insecurity among schoolchildren living in urban and rural areas of Picos, Piauí associated with the socioeconomic profile of families and their food intake and nutritional status. Methods: Study participants were families with children aged 7-10 years enrolled in municipal schools, totaling 342 families/schoolchildren. The study was conducted at school facilities through interviews with mothers - or guardians - using a questionnaire based on the Brazilian Food Insecurity Scale and socioeconomic variables and food frequency questionnaire. The nutritional status of children was assessed using the following indexes: weight/age, height/age and body mass index/age. Results: The prevalence of food insecurity was high and similar for rural and urban areas, 84.3% and 83.3%, respectively. In general, lower income and consumption of untreated water was associated with greater frequency of food insecurity (p≤0.01. In urban areas, higher percentage of food insecurity was associated to lower educational levels (p≤0.05. Dietary intake and nutritional status of schoolchildren were not associated with food insecurity condition of families. Conclusion: The percentage of families at food insecurity, as well as the food consumption and nutritional status of schoolchildren were similar between urban and rural areas, characterized as a homogeneous population in terms of socioeconomic conditions.

    Full Text Available Sociological investigations regarding urbanization processes show an irreversible tendency: the number of urban residents will double in the next 35 years. Big cities rather than villages and provincial boroughs become our common habitat. Agriculture practiced in the proximity of big urban areas (intra- and peri-urban agriculture is one of the powerful and positive activities that the municipal residents can carry out in their effort to take control of their food security, aberrant social behavior and environment degradation in the urban communities. This paper approaches the central themes of the researches carried out in the field of urban agriculture: magnitude and dynamics of agricultural practices in the proximity of big urban areas, types of agriculture practiced, benefits and hazards associated to these practices, social implications and economical results of agricultural initiatives in urban sites, environmental impact of the mutual influence urban environment – agricultural sites, accessibility, cropping suitability, and ecological conversion of land in the proximity of urban areas. Socio-economical impact is analyzed, referring to the agricultural used land, its legal status, and crop structure in Bucharest municipality, social and economical motivation of agricultural producers, incomes from agricultural activities, identified constraints in the development of agricultural activities and perspectives, information sources, connection degree with the specific institutions and to the demands of ecological agriculture practice. Environment impact assessment was carried out by processing some fertility and contamination/pollution macro-indicators, which refer to the soil and ground water loading and pollution with nitrates, organochlorines, polychlorinated byphenyls (PCB, polynuclear aromatic hydrocarbons (PAH and heavy metals.

Methods Using 2005–2006 data from Demographic Health Surveys (Armenia, Azerbaijan, and Moldova and Multiple Indicator Cluster Surveys (Belarus, Georgia, Kazakhstan, Kyrgyzstan, Tajikistan, Ukraine, and Uzbekistan, we examined associations between individual and community socioeconomic status with current modern contraceptive use (MCU among N = 55,204 women aged 15–49 married or in a union. Individual socioeconomic status was measured using quintiles of wealth index and education level (higher than secondary school, secondary school or less. Community socioeconomic status was measured as the percentage of households in the poorest quintile of the nationals household wealth index (0%, 0–25%, or greater than 25%. We used multilevel logistic regression to estimate associations adjusted for age, number of children, urban/rural, and socioeconomic variables. Results MCU varied by country from 14% (in Azerbaijan to 62% (in Belarus. Overall, women living in the poorest communities were less likely than those in the richest to use modern contraceptives (adjusted odds ratio (aOR = 0.82, 95% Confidence Interval = 0.76, 0.89. Similarly, there was an increasing odds of MCU with increasing individual-level wealth. Women with a lower level of education also had lower odds of MCU than those with a higher level of education (aOR = .75, 95%CI = 0.71, 0.79. In country-specific analyses, community-level socioeconomic inequalities were apparent in 4 of 10 countries; in contrast, inequalities by individual-level wealth were apparent in 7 countries and by education in 8 countries.

The biggest proportion of population depends on it. Being a developing country, the development of agriculture is more essential as compared to other developed countries like U.S.A., Japan, U.S.S.R. and Germany etc. Our country is facing a lot of challenges in the rural sector. Majority of people belong to the downtrodden sector and have no promising source of Information. Resulting in poor decision making ability in innumerable indispensible areas of the rural society, which affects the quality of their life, since information plays a vital role to augment the agricultural production. All kinds of compatible and valuable information become helpful in decision making and planning the future strategy accordingly, meagre productions in agriculture enhance this problem profoundly. People are compelled to live in misery with fear. Uttar Pradesh is the second largest state-economy in India; It contributed 8.23 per cent to India's total Gross domestic product (GDP in the financial year 2013-2014.[1] Agriculture is a significant part of Uttar Pradesh's economy.5Study was conducted in Kanpur Dehat district of Uttar Pradesh. The district suffers from lack of rainfall, low soil fertility, traditional cropping pattern and poor communication facilities etc. Socio-economic status of respondents plays a vital role in online communication for rural development.

    Despite the prevalence of protected areas, evidence of their impacts on people is weak and remains hotly contested in conservation policy. A key question in this debate is whether socioeconomic impacts vary according to social subgroup. Given that social inequity can create conflict and impede poverty reduction, understanding how protected areas differentially affect people is critical to designing them to achieve social and biological goals. Understanding heterogeneous responses to protected areas can improve targeting of management activities and help elucidate the pathways through which impacts of protected areas occur. Here, we assessed whether the socioeconomic impacts of marine protected areas (MPAs)-designed to achieve goals for both conservation and poverty alleviation-differed according to age, gender or religion in associated villages in North Sulawesi, Indonesia. Using data from pre-, mid- and post-implementation of the MPAs for control and project villages, we found little empirical evidence that impacts on five key socioeconomic indicators related to poverty differed according to social subgroup. We found suggestive empirical evidence that the effect of the MPAs on environmental knowledge differed by age and religion; over the medium and long terms, younger people and Muslims showed greater improvements compared with older people and Christians, respectively.

    Full Text Available Abstract Background Fast food restaurants reportedly target specific populations by locating in lower-income and in minority neighborhoods. Physical proximity to fast food restaurants has been associated with higher obesity rates. Objective To examine possible associations, at the census tract level, between area demographics, arterial road density, and fast food restaurant density in King County, WA, USA. Methods Data on median household incomes, property values, and race/ethnicity were obtained from King County and from US Census data. Fast food restaurant addresses were obtained from Public Health-Seattle & King County and were geocoded. Fast food density was expressed per tract unit area and per capita. Arterial road density was a measure of vehicular and pedestrian access. Multivariate logistic regression models containing both socioeconomic status and road density were used in data analyses. Results Over one half (53.1% of King County census tracts had at least one fast food restaurant. Mean network distance from dwelling units to a fast food restaurant countywide was 1.40 km, and 1.07 km for census tracts containing at least one fast food restaurant. Fast food restaurant density was significantly associated in regression models with low median household income (p Conclusion No significant association was observed between census tract minority status and fast food density in King County. Although restaurant density was linked to low household incomes, that effect was attenuated by arterial road density. Fast food restaurants in King County are more likely to be located in lower income neighborhoods and higher traffic areas.

The geometric mean (GM levels of blood lead were 1.73 μg/dL (range 0.02–9.26 and 1.56 μg/dL (range 0.02–6.83 for male and female children, respectively. The blood lead levels were significantly higher in males, children living in rural areas, and those with lower individual SEP. The GM levels of blood mercury were 2.07 μg/L (range 0.09–12.67 and 2.06 μg/L (range 0.03–11.74 for males and females, respectively. Increased blood mercury levels were significantly associated with urban areas, higher individual SEP, and more deprived communities. The risk of high blood lead level was significantly higher for the lower individual SEP (odds ratio (OR 2.18, 95% confidence interval (CI 1.36–3.50 in the lowest educational attainment of the father, with a significant dose-response relationship observed after adjusting for the community SEP. The association between high blood lead levels and lower individual SEP was much stronger in the more deprived communities (OR 2.88, 95% CI 1.27–6.53 than in the less deprived communities (OR 1.40, 95% CI 0.76–2.59, and showed a significant decreasing trend during the follow-up only in the less deprived communities. The risk of high blood mercury levels was higher in higher individual SEP (OR 0.64, 95% CI 0.40–1.03 in the lowest educational attainment of the father, with a significant dose-response relationship noted. Significant decreasing trends were observed during the follow-up both in the less and more deprived communities.

    Full Text Available Infectious diarrhea, a common disease of children, deserves permanent monitoring in all social groups. To know the etiology and clinical manifestations of acute diarrhea in children up to 5 years of age from high socioeconomic level households, we conducted a descriptive, microbiological, and clinical study. Stools from 59 children with acute community-acquired diarrhea were examined, and their parents were interviewed concerning symptoms and signs. Rotavirus, adenovirus, and norovirus were detected by commercially available qualitative immunochromatographic lateral flow rapid tests. Salmonella, Campylobacter, Yersinia, and Shigella were investigated by standard bacteriological methods and diarrheagenic E. coli by PCR assays. We identified a potential enteric pathogen in 30 children. The most frequent causes of diarrhea were enteropathogenic E. coli (EPEC, viruses, Campylobacter, Salmonella, and Shiga-toxin-producing E. coli (STEC. Only 2 patients showed mixed infections. Our data suggest that children with viral or Campylobacter diarrhea were taken to the hospital earlier than those infected with EPEC. One child infected with STEC O26 developed “complete” HUS. The microbiological results highlight the importance of zoonotic bacteria such as atypical EPEC, Campylobacter, STEC, and Salmonella as pathogens associated with acute diarrhea in these children. The findings also reinforce our previous communications about the regional importance of non-O157 STEC strains in severe infant food-borne diseases.

    2014-05-01

    The MontanAqua project aims to study the water resources management in the region Sierre-Montana (Valais, Switzerland). Land use is known to have an influence on the water resources (soil moisture dynamic, soil sealing, surface runoff and deep percolation). Thus land use modelling is of importance for the water resources management. An actual land use map was produced using infrared imagery (Niklaus 2012, Fig.1). Land use changes are known to be mainly drived by socio-economic factors as well as climatic factors (Dolman et al. 2003). Potential future Land uses was separatly predicted according to 1-. socio-economic and 2-. climatic/abiotic drivers : 1. 4 socio-economic scenarios were developped with stakeholders (Schneider et al. 2013) between 2010 and 2012. We modeled those socio-economic scenarios into a GIS application using Python programming (ModelBuilder in ArcGIS 10) to get a cartographic transcription of the wishes of the stakeholders for their region in 2050. 2. Uncorrelated climatic and abiotic drivers were used in a BIOMOD2 (Georges et al. 2013) framework. 4 models were used: Maximum Entropy (MAXENT), Multiple Adaptive Regression Splines (MARS), Classification Tree Analysis (CTA) and the Flexible Discriminant Analysis (FDA) to predict grassland, alpine pasture, vineyards and forest in our study region. Climatic scenarios were then introduced into the models to predict potential land use in 2050 driven only by climatic and abiotic factors The comparison of all the outputs demonstrates that the socio-economic drivers will have a more important impact in the region than the climatic drivers (e.g. -70% grassland surface for the worst socio-economic scenario vs. -40% of grassland surface for the worst climatic models). Further analysis also brings out the sensitivity of the grassland/alpine pasture system to the climate change and to socio-economic changes. Future work will be to cross the different land use maps obtained by the two model types and to use

    Full Text Available Abstract Background Strategies for cancer reduction and management are targeted at both individual and area levels. Area-level strategies require careful understanding of geographic differences in cancer incidence, in particular the association with factors such as socioeconomic status, ethnicity and accessibility. This study aimed to identify the complex interplay of area-level factors associated with high area-specific incidence of Australian priority cancers using a classification and regression tree (CART approach. Methods Area-specific smoothed standardised incidence ratios were estimated for priority-area cancers across 478 statistical local areas in Queensland, Australia (1998-2007, n = 186,075. For those cancers with significant spatial variation, CART models were used to identify whether area-level accessibility, socioeconomic status and ethnicity were associated with high area-specific incidence. Results The accessibility of a person's residence had the most consistent association with the risk of cancer diagnosis across the specific cancers. Many cancers were likely to have high incidence in more urban areas, although male lung cancer and cervical cancer tended to have high incidence in more remote areas. The impact of socioeconomic status and ethnicity on these associations differed by type of cancer. Conclusions These results highlight the complex interactions between accessibility, socioeconomic status and ethnicity in determining cancer incidence risk.

    Full Text Available Nighttime light imagery offers a unique view of the Earth’s surface. In the past, the nighttime light data collected by the DMSP-OLS sensors have been used as an efficient means to correlate regional and global socio-economic activities. With the launch of the Suomi National Polar-orbiting Partnership (Suomi-NPP satellite in 2011, the day-night band (DNB of the Visible Infrared Imaging Radiometer Suite (VIIRS onboard represents a major advancement in nighttime imaging capabilities, because it surpasses its predecessor DMSP-OLS in radiometric accuracy, spatial resolution and geometric quality. In this paper, four variables (total night light, light area, average night light and log average night light are extracted from nighttime radiance data observed by the VIIRS-DNB composite in 2013 and nighttime digital number (DN data from the DMSP-OLS stable dataset in 2012, respectively, and correlated with 12 socio-economic parameters at the provincial level in mainland China during the corresponding period. Background noise of DNB composite data is removed using either a masking method or an optimal threshold method. In general, the correlation of these socio-economic data with the total night light and light area of VIIRS-DNB composite data is better than with the DMSP-OLS stable data. The correlations between total night light of denoised DNB composite data and built-up area, gross regional product (GRP and power consumption are higher than 0.9 and so are the correlations between the light area of denoised DNB composite data and city and town population, built-up area, GRP, power consumption and waste water discharge. However, the correlations of socio-economic data with the average night light and log average night light of VIIRS-DNB composite data are not as good as with the DMSP-OLS stable data. To quantitatively analyze the reasons for the correlation difference, a cubic regression method is developed to correct the saturation effect of the DMSP

    2012-04-01

    Full Text Available This study focused on the socio-economic analysis of the operational impacts of Shiroro hydroelectric power generation dam in the lowland areas of middle river Niger in Nigeria. The paper observed that more than thirty years since the conception and impoundment of water at Kanji over river Niger a number of action or inaction capable of altering the socio-economic profile of the riparian communities around the lowland areas of middle river Niger in Nigeria have taken place. The study therefore designed and administered a close-ended pre-coded instrument to conduct a survey of the dam affected communities located in the study area. The data harvested were analyzed using the Principal Component Analysis (PCA. The result obtained shows that the economic engagements of the riparian communities have been distorted. This is noticeable especially on both fish biodiversity and ecosystem with a resultant loss of fish-species. There is a dismal fall in productivity of small holder farmers and fishermen occasioned by avoidable flooding. In the same vein Strategic social and economic infrastructure have deteriorated and thus slowed down the socio and economic development in the area. In this connection a number of policy measures to mitigate the negative effect of hydropower production were suggested.

    Full Text Available The main purpose of this study was to investigate the links between forest dwellers’ participation in reforestation and development of forest areas in west Mazandaran of Iran and a set of socio-economic variables. The statistical population includes all forest dwellers living in villages, which locate in the west Mazandaran in Iran and had been covered by local forestry cooperative. A sample of 110 forest dwellers were selected by the use of proportional random sampling method. A questionnaire was used to collect data. For determining the validity of questionnaire, the content validity was used. Cronbach's alpha was used to measure reliability of the index measuring level of participation in reforestation and development of forest areas that its extent was 0.86 and showed that mentioned variable had high reliability. The data were analyzed by the use of descriptive and inferential statistics such as extent of mean, standard deviation, coefficient of variation, correlation analysis and regression analysis. The findings revealed that age, level of literacy, level of participation in extension-education courses, using level of communication channels and information resources, level of forest dependency, social participation, social solidarity, economic and social motivations are positively and significantly (p<0.01 correlated with level of forest dwellers' participation in reforestation and development of forest areas. Household size is positively and significantly (p<0.05 correlated with level of forest dwellers' participation in reforestation and development of forest areas. The result of multiple regression showed that variables of level of participation in extension-education courses, age, household size, level of economic motivation, social solidarity and level of literacy could explain 51.4% of the variation in the level of forest dwellers' participation in reforestation and development of forest areas.

  17. Low and intermediate level waste repositories: Socioeconomic aspects and public involvement. Proceedings of a workshop

    International Nuclear Information System (INIS)

    Waste management facilities are needed to protect the environment and improve public health for the long term future. One significant challenge is to inform the public on the relative hazards of radioactive waste compared to other hazards in our modern society and to get the acceptance of the appropriate members of the public for these necessary facilities. Over the entire life cycle of these facilities, the projects must be managed without expending a disproportionate share of the collective resources. Public involvement plays a key role and the sophisticated and extensive public education systems that exist provide a vital service to gain public acceptance. There is a full range of compensation and benefit programmes used as incentives for hosting a LILW facility. Even if exemptions exist the experience in most countries indicate the direct/indirect incentives as a necessary part of gaining public acceptance. The countries, regions and local communities have their own established processes to make public decisions. Each organization developing a site must select and implement the methods that are acceptable within their framework of laws and regulations. A three day workshop on socio-economic issues and public involvement practices and approaches for developing and operating repositories for low and intermediate level waste took place in the IAEA headquarters on 9-11 November 2005. The workshop provided a forum where experts from Member States shared their experiences in non-technical aspects of planning, licensing and operating LILW disposal facilities. Description of both principles and practices applied in particular countries provides a useful overview of potential approaches in application of non-technical issues during a repository lifecycle. Participants presented approaches and practices applied in their countries, established new contacts and were able to take advantage of activities and experiences from abroad. There were 25 interesting presentations

    This note gives a short introduction of how to make socio-economic evaluations in connection with the teaching at the Centre for Traffic and Transport (CTT). It is not a manual for making socio-economic calculations in transport infrastructure projects – in this context we refer to the guidelines...... for socio-economic calculations within the transportation area (Ministry of Traffic, 2003). The note also explains the theory of socio-economic calculations – reference is here made to ”Road Infrastructure Planning – a Decision-oriented approach” (Leleur, 2000). Socio-economic evaluations of...... infrastructure projects are common and can be made at different levels of detail depending on the type of project and the decision making phase. A common feature of the different levels of detail of the socio-economic analysis is that the planned project(s) is compared with a basic; the basic alternative or a...

  19. Socioeconomic issues and public involvement practices and approaches for developing and operating repositories for low and intermediate level waste UK perspective

    International Nuclear Information System (INIS)

    The United Kingdom (UK) currently has one national disposal facility for low level radioactive waste (LLW), which is located 6km south of the Sellafield site in Cumbria. The Low Level Waste Repository has been in operation for over 40 years and is operated by British Nuclear Group. LLW is also disposed of at the United Kingdom Atomic Energy Authority (UKAEA) operated Dounreay site in Scotland, but here only waste generated from that particular site is retained. The authorized disposal of intermediate level waste (ILW) took place at Dounreay within a shaft, primarily between the years of 1958 and 1977. The UK does not currently have a national waste repository for ILW, although a siting exercise was conducted by Nirex during the 1990's. This exercise was stopped in 1997 when an application to construct a rock characterization facility was turned down. The successful siting, development and ultimate operation of repositories, whether they be for low or intermediate level waste relies on a sound programme of public involvement and consideration of socioeconomic issues. This paper will focus primarily on the socioeconomic issues and public involvement practices undertaken at the Low Level Waste Repository coupled with the work undertaken by Nirex both during their siting exercise and subsequent to this. Work underpinning the adopted strategies for the LLW and ILW disposal areas at Dounreay will be discussed only briefly since they are not national facilities. Over the last ten years there has been a marked increase in the level of stakeholder engagement and consideration of socioeconomic issues in response to wider societal changes. A wide range of site specific, regional and national dialogues have taken place. The lessons learned from earlier programmes have been incorporated into the more recent and current approaches, especially with an increased emphasis on local benefits. (author)

    The purpose of this study is to reveal relations between access to electricity and advancement in a socio-economic condition in rural areas of developing countries. Recently, multi-dimensional aspects of poverty, for example, economy, education, and health, has been increasingly focused on, and access to modern energy such as electricity is one possible solution. As a case study, we have analyzed unelectrified rural areas in Assam state, India. We have developed an energy-economic model in order to analyze the possibility of electrification through dissemination of electric lighting appliances as well as applied multiple regression analysis to estimate the socio-economic condition, a literacy rate above 6 years old, in the areas. As a result of the case study, the household electrification rate, the 1000 km2 road density, and sex ratio have been chosen as the explanatory variables of the literacy rate. Moreover, the model analysis shows that complete household electrification will be achieved by the year 2012. In combination with the multiple regression and model analysis, the literacy rate in Assam may increase to 74.4% from 63.3%

    Alam, Rashidah Zainal; Siwar, Chamhuri; Ludin, Norasikin Ahmad

    Malaysia's energy sector is highly dependent on fossil fuels as a primary energy source. Economic growth and socio-economic wellbeing also rely on the utilization of energy in daily life routine. Nevertheless, the increasing cost for electricity and declining fossil fuels resources causes various negative impacts to the people and environment especially in rural areas. This prompted Malaysia to shift towards alternative energy sources such as solar energy to ensure social, economic and environmental benefits. The solar energy is one of the potential renewable energy sources in tropical countries particularly in Malaysia. The paper attempts to analyze the benefits and advantages related to energy efficiency of solar for sustainable energy use and socio economic wellbeing in rural areas, Malaysia. The paper uses secondary sources of data such as policies, regulations and research reports from relevant ministries and agencies to attain the objectives. As a signatory country to the UN Convention on Climate Change and the Kyoto Protocol, Malaysia has taken initiatives for decreasing energy dependence on oil to reduce greenhouse gas emissions (GHG) for sustainable development. The paper shows solar energy becomes one of the promising alternative energy sources to alleviate energy poverty in Malaysia for rural areas. Finally, solar energy has increased socio-economic wellbeing and develops green potential and toward achieving energy efficiency in energy sector of Malaysia by preserving environment as well as reducing carbon emission.

    2015-12-01

    In rural areas where farming competes with urban development and environmental amenities, urban and forest transitions occur simultaneously at different locales with different rates due to the underlying socio-economic shifts. Here we develop an interactive land use transition agent-based model (ILUTABM) in which farmers' land use decisions are made contingent on expansion and location choices of urban businesses and urban residences, as well as farmers' perceived ecosystem services produced by their land holdings. The ILUTABM simulates heterogeneity in land use decisions at parcel levels by differentiating decision making processes for agricultural and urban landowners. Landowners are simulated to make land-use transition decisions as bounded rational agents that maximize their partial expected utility functions under different underlying socio-economic conditions given the category of a landowner and the spatial characteristics of the landowner's landholdings. The ILUTABM is parameterized by spatial data sets such as National Land Cover Database (NLCD), zoning, parcels, property prices, US census, farmers surveys, building/facility characteristics, soil, slope and elevation. We then apply the ILUTABM to the rural Vermont landscape, located in the Northeast Arm District of Lake Champlain and the downstream sub-watersheds of Missisquoi River, to generate phase transitions of rural land towards urban land near peri-urban areas and towards forest land near financially stressed farmlands during 2001-2051. Possible tipping point trajectories of rural land towards regional forest or urban transition are simulated under three socio-economic scenarios: business as usual (ILUTABM calibrated to 2011 NLCD), increased incentives for conservation easements, and increased incentives for attracting urban residences and businesses.

    Full Text Available Extended abstract1-IntroductionOver the last few decades, urban marginalization has been a major challenge in the metropolitan and large cities. After various experiences of forcible contact, what is recommended by international organizations is an empowerment approach which focuses on the empowerment of squatters instead of financial support. In this study, Ahar squatters were identified and investigated in 4 neighborhoods. Using Cochran formula, 320 samples were chosen randomly and their economic, social, physical and spatial characteristics of neighborhoods were collected by questionnaires and then analyzed by SPSS software. Besides, using SWOT approach and identifying problems, strategies of Empowerment in different dimensions was presented. Results showed that Shileboran and Nirugah neighborhoods have more problems regarding socio-economic and physical status, whereas Chalabverdi neighborhood has better situation than other neighborhoods. Ownership issue, poor housing conditions, access problems and poor sewage system were serious problems for residents of these neighborhoods. 2- Theoretical basesIn the second decades of 1980s, empowerment strategies along with improvement in informal habitat settings are recommended to overlook the poor economic condition of families and also the inability to use the collective power. Therefore, a great leap was created in modern approach which is based on the improvement of local communities and macro policies. The entity of the empowerment approach is based on the reduction of poverty and in human-oriented sustainable development it is based on the citizen participation.3– DiscussionThe problem of informal settlements in Ahar city because of its geographical location as a city in northeast of Azerbaijan province and its situation in the middle of bundles of small and big villages has been accelerated to the extent that solving the problem has been a real challenge. Investigation of the situation of

  9. Socio-economic analysis of fuelwood use in a rural area of Turkey

    International Nuclear Information System (INIS)

    The present article is based on the socio-economic analysis of fuelwood use in 70 villages in Trabzon, Turkey. Energy requirements of the 70 villages studied are subsidized considerably by the surrounding forest in the form of firewood. It was noticed that the amount of fuelwood consumption in the 70 villages was 171 371 m3 in 1990. The total amount of fuelwood per house provided by the forest enterprise was 12 212 m3 in the same year and, therefore, the amount of illegal fuelwood consumption was 159 160 m3. This study showed that the amount of fuelwood provided by the forest enterprise for each house in the villages was only 7% of the amount of fuelwood in the villages used. Finally, the economic, social, cultural, legal, technical, managerial and psychological reasons for the illegal fuelwood consumption from the State Forests have been studied and necessary and appropriate solutions have been proposed.

  12. The effect of environmental factors on breast lumps of Egyptian women in different socioeconomic levels

    International Nuclear Information System (INIS)

    The environmental risk factors related to the breast tumors (lumps) are essential in order to build strategies to decrease cancer incidence and mortality among different socioeconomic and cultural backgrounds. A case control study of 70 cases and 52 controls were classified into high, middle and low socioeconomic classes. The results revealed significant increased risk of breast tumors among working females, having positive family history, married with lower mean parity, with higher consumption of fatty meals, lesser meat intake. Non significant risk factors were the social class, exposure to ionizing radiation, non lactating. wearing tight bra, consumption of vegetables and fruits, oral contraceptive pill users and exposure to outdoor air pollution or indoor pollution as floors and wall paintings. In conclusion, this study highlights the positive life style for egyptian women so they can prevent some of the environmental risks of breast tumors. Increasing the awareness of breast diseases and regular examination remains the corner stone for early detection management of breast lumps.

  14. Socio-economic issues and public involvement in the development and operation of low and intermediate level radioactive waste repository

    International Nuclear Information System (INIS)

    The final ground radioactive waste disposal appears to be the optimal option for low- and intermediate-level activity wastes resulting from operation and decommissioning activities at Cernavoda NPP. Taking into account the international experience in implementing and developing repositories of this type as well as the specific requirements in the stages of planning, ANDRAD approached technical procedures concerning repository extension, safety and environmental impact. Also non-radiologic impact and socio-economic aspects for the life-time span of the facility were analyzed. All the stages from initial planning through, site selection, construction, operation, shutdown and institutional post-shutdown control were considered from the environmental point of view. Different factors of natural environment (land resources, air quality, water resources, etc) as well as economical conditions (local economic status, manpower occupation) and social conditions (dwellings, services, education, utility supply) should be thoroughly analyzed. The financing issues will obviously have an essential bearing on schedule referring to the implementation, development, operation and eventual shutdown of the repository. Finally the paper presents the methods which ANDRAD should approach in order to have the local community familiarized with the nuclear operations at Cernavoda NPP, a factor of paramount importance for localizing the radioactive waste repository within the NPP siting area. This co-location solution was chosen as optimal from the point of view of both the project's cost and the non-radiological impact. The paper has the following contents: 1.Introduction; 2.Objective, scope and structure; 3.Repository concept and life cycle; 4.Policy, public involvement and cost considerations; 5.Potential impacts during the repository life cycle; 6.Impact management; 7.Conclusions

  18. Airborne silica levels in an urban area

    International Nuclear Information System (INIS)

    In order to evaluate the exposure levels of the general population we studied the concentrations of silica particles in the inhalable particulate fraction (PM10) in different meteorological-climate periods in an urban area of Rome. In order to determine the concentration and the granulometric spectrum of silica particles, PM10 sampled by a cascade impactor was analysed by X-ray diffractometry (XRD) and by scanning electron microscopy equipped with a thin-window system for X-ray microanalysis (SEM/EDX). Over the period September 2004-October 2005 the abundance of silica particles as evaluated by SEM/EDX ranged from 1.6 to 10.4% of the total PM10 particulate, with a weight concentration of free crystalline silica, evaluated by XRD, in the range 0.25-2.87 μg/m3. The mean diameter of silica particles ranged from 0.3 to 10.5 μm, with more than 87% of particles having a diameter of less than 2.5 μm. The correlations between SEM/EDX and XRD data seem to suggest that the airborne silica particles in the urban location studied were mainly in the form crystalline silica. A strong relationship was found between the meteorological-climate conditions and the concentration level of free crystalline silica. This result suggests that the Southern winds from the Sahara desert carry an important amount of silica particles into Mediterranean Europe

    The aim of the present nationwide Greek study is to assess whether survival from acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML) is modified by socioeconomic status (SES) and area remoteness. Detailed precoded information derived from a personal interview conducted by specially trained health personnel with the child guardians was available for 883 ALL and 111 AML incident childhood cases registered in the Nationwide Registry for Childhood Hematological Malignancies during the period 1996-2010. Parental socioprofessional category was recorded on the basis of ISCO68 and ISCO88 codes; the exact traveling distance between residence and the treating hospital was ad hoc calculated. Multivariate Cox's proportional hazards models were applied to examine the mutually adjusted associations between survival and potential predictors. Children from a lower parental socioprofessional category experienced 40% worse survival (P=0.02) independent of age, sex, and ALL subtype, whereas those whose parents were married had better outcomes (rate ratio: 0.47, P=0.01). Urbanization of residence at diagnosis or 'residence to treating hospital' distance was not nominally associated with survival from ALL. By contrast, no noteworthy associations implicating SES were found for AML survival, probably because of the burden of the disease and small numbers. Lower SES indicators and a single-parenthood family milieu seem to be independently associated with unfavorable outcomes from childhood ALL. Area remoteness might not be a significant outcome predictor during recent years, following considerable improvements in the motorway infrastructures and care delivery patterns. This study may provide a valuable snapshot capturing the impact of socioeconomic covariates before the burst of the Greek financial crisis. PMID:23238585

    The aim of this study is to investigate the association of allergic rhinitis in female university students with socio-economic factors and sex-hormone markers, including age at menarche, menstrual disorders, and selected anthropometrics indexes. The research was conducted among 640 female university students, aged 19-25 years. The measurements of body height, body mass, waist and hip circumference were taken. Each person completed a questionnaire. The occurrence of allergy was determined on the basis of answers to the questions whether the allergy and its allergens were defined on the basis of medical workup. We found that a significantly larger number of cases of allergic rhinitis were recorded in the university students coming from families of high socio-economic level than those from lower level. Allergic rhinitis also was more frequent in the students who spent their childhood in cities than in those who lived in the countryside. The prevalence of allergic rhinitis was inversely correlated to the number of siblings. There were no differences in the prevalence of allergic rhinitis in relation to the birth order. The estrogen level seemed unassociated with rhinitis. However, there were slightly more allergic among females with an earlier age of menarche. PMID:26453067

    Full Text Available Introduction: HIV infection may be affected by multiple complex socioeconomic status (SES factors, especially individual socioeconomic disadvantage and community-level inequality. At the same time, stigma towards HIV and marginalized groups has exacerbated persistent concentrated epidemics among key populations, such as persons who inject drugs (PWID in Vietnam. Stigma researchers argue that stigma fundamentally depends on the existence of economic power differences in a community. In rapidly growing economies like Vietnam, the increasing gap in income and education levels, as well as an individual's absolute income and education, may create social conditions that facilitate stigma related to injecting drug use and HIV. Methods: A cross-sectional baseline survey assessing different types of stigma and key socioeconomic characteristics was administered to 1674 PWID and 1349 community members living in physical proximity throughout the 32 communes in Thai Nguyen province, Vietnam. We created four stigma scales, including HIV-related and drug-related stigma reported by both PWID and community members. We then used ecologic Spearman's correlation, ordinary least-squares regression and multi-level generalized estimating equations to examine community-level inequality associations, individual-level SES associations and multi-level SES associations with different types of stigma, respectively. Results: There was little urban–rural difference in stigma among communes. Higher income inequality was marginally associated with drug-related stigma reported by community members (p=0.087, and higher education inequality was significantly associated with higher HIV-related stigma reported by both PWID and community members (p<0.05. For individuals, higher education was significantly associated with lower stigma (HIV and drug related reported by both PWID and community members. Part-time employed PWID reported more experiences and perceptions of drug

    The country India follows the planning through planning commission. This is on the basis of information collected by traditional, tedious and manual method which is too slow to sustain. Now we are in the age of 21th century. We have seen in last few decades that the progress of information technology with leaps and bounds, which have completely changed the way of life in the developed nations. While internet has changed the established working practice and opened new vistas and provided a platform to connect, this gives the opportunity for collaborative work space that goes beyond the global boundary. We are living in the global economy and India leading towards Liberalize Market Oriented Economy (LMOE). Considering this things, focusing on GIS, we proposed a system for collection of socio economic data and water resource management information of rural area via internet.

    Full Text Available Introduction: Cardiovascular Disease (CVD has been linked to "neighbourhood" socioeconomic status (nSES, often operationalized as a composite index of aggregate income, occupation and education within predefined administrative boundaries. The role of specific, non-composite socioeconomic markers has not been clearly explained. It is also unclear whether the relationship between nSES and CVD varies according to sex. We sought to determine whether area-level unemployment (ALU was associated with CVD risk, and whether this association differed by sex. Methods: 342 individuals from the Montreal Neighbourhood Survey of Lifestyle and Health provided self-reported behavioural and socioeconomic information. A nurse collected biochemical and anthropometric data. ALU, a weighted average of the proportion of persons 15-years and older available for but without work, was measured using a Geographic Information System for a 250 m buffer centred on individual residence. Generalized Estimating Equations were used to estimate the associations between ALU, body mass index (BMI and a cumulative score for total cardiometabolic risk (TCR. Results: After confounder adjustments, the mean 4th minus 1st quartile difference in BMI was 3.19 kg/m2 (95% CI: 2.39, 3.99, while the prevalence ratio for the 4th relative to 1st quartile for TCR was 2.20 (95 % CI: 1.53, 3.17. Sex interacted with ALU; women relative to men had greater mean 3.97 kg/m2 (95% CI: 2.08, 5.85 BMI and greater mean TCR 1.51 (95% CI: 0.78, 2.90, contrasted at mean ALU. Conclusions: Area-level unemployment is associated with greater CVD risk, and this association is stronger for women.

  6. Spatial, socio-economic, and ecological implications of incorporating minimum size constraints in marine protected area network design.

    Marine protected areas (MPAs) are the cornerstone of most marine conservation strategies, but the effectiveness of each one partly depends on its size and distance to other MPAs in a network. Despite this, current recommendations on ideal MPA size and spacing vary widely, and data are lacking on how these constraints might influence the overall spatial characteristics, socio-economic impacts, and connectivity of the resultant MPA networks. To address this problem, we tested the impact of applying different MPA size constraints in English waters. We used the Marxan spatial prioritization software to identify a network of MPAs that met conservation feature targets, whilst minimizing impacts on fisheries; modified the Marxan outputs with the MinPatch software to ensure each MPA met a minimum size; and used existing data on the dispersal distances of a range of species found in English waters to investigate the likely impacts of such spatial constraints on the region's biodiversity. Increasing MPA size had little effect on total network area or the location of priority areas, but as MPA size increased, fishing opportunity cost to stakeholders increased. In addition, as MPA size increased, the number of closely connected sets of MPAs in networks and the average distance between neighboring MPAs decreased, which consequently increased the proportion of the planning region that was isolated from all MPAs. These results suggest networks containing large MPAs would be more viable for the majority of the region's species that have small dispersal distances, but dispersal between MPA sets and spill-over of individuals into unprotected areas would be reduced. These findings highlight the importance of testing the impact of applying different MPA size constraints because there are clear trade-offs that result from the interaction of size, number, and distribution of MPAs in a network.

    Full Text Available Abstract Background The aim of this study was analyze associations between the practice of walking and environmental perception among elderly Brazilians in a region of low socioeconomic level. Methods A cross-sectional study was conducted among 385 elderly people aged 60 years and over. To evaluate walking, the International Physical Activity Questionnaire (IPAQ, long version (leisure and transport modules was used. The environment was evaluated by means of the Neighborhood Environmental Walkability Scale (NEWS (adapted Brazilian version. For the statistical analysis, multiple logistic regression models were created separately for men and women. The practice of at least 150 minutes a week of walking was the dependent variable, and the variables of environmental perception were the independent variables. All the models were controlled for schooling level and age. Results The proportion of elderly people active in walking was 56.9% for the men and 26.4% for the women. The perception of the presence of soccer fields (OR = 4.12 and their proximity, within ten minutes' walk from home (OR = 3.43, were associated with the practice of walking among the men. The perception of the presence of public squares (OR = 4.70 and the proximity of primary healthcare units, within ten minutes' walk from home (OR = 3.71, were associated with the practice of walking among the women. An association with adequate perception of vehicle traffic remained at the threshold of significance for the women. Conclusion Accessibility of leisure structures such as football fields and public squares and of health services such as primary healthcare units were important environmental variables associated with the practice of walking among elderly people living in a region of low socioeconomic level in Brazil. These variables need to be taken into consideration when aiming to promote the practice of walking among elderly people living in similar regions.

    Full Text Available Abstract Background In Australia, associations between geographic remoteness, socioeconomic disadvantage, and colorectal cancer (CRC survival show that survival rates are lowest among residents of geographically remote regions and those living in disadvantaged areas. At present we know very little about the reasons for these inequalities, hence our capacity to intervene to reduce the inequalities is limited. Methods/Design This study, the first of its type in Australia, examines the association between CRC survival and key area- and individual-level factors. Specifically, we will use a multilevel framework to investigate the possible determinants of area- and individual-level inequalities in CRC survival and quantify the relative contribution of geographic remoteness, socioeconomic and demographic factors, disease stage, and access to diagnostic and treatment services, to these inequalities. The multilevel analysis will be based on survival data relating to people diagnosed with CRC in Queensland between 1996 and 2005 (n = 22,723 from the Queensland Cancer Registry (QCR, area-level data from other data custodians such as the Australian Bureau of Statistics, and individual-level data from the QCR (including extracting stage from pathology records and Queensland Hospitals. For a subset of this period (2003 and 2004 we will utilise more detailed, individual-level data (n = 1,966 covering a greater range of risk factors from a concurrent research study. Geo-coding and spatial technology will be used to calculate road travel distances from patients' residence to treatment centres. The analyses will be conducted using a multilevel Cox proportional hazards model with Level 1 comprising individual-level factors (e.g. occupation and level 2 area-level indicators of remoteness and area socioeconomic disadvantage. Discussion This study focuses on the health inequalities for rural and disadvantaged populations that have often been documented but poorly

    Full Text Available Abstracts Background With regards to equity, the objective for health care systems is “equal access for equal needs”. We examined associations of predisposing, enabling and need factors with health facility utilization in areas with high HIV prevalence and few people being aware of their HIV status. Methods The data is from a population-based survey among adults aged 15years or older conducted in 2003. The current study is based on a subset of this data of adults 15–49 years with a valid HIV test result. A modified Health behaviour model guided our analytical approach. We report unadjusted and adjusted odds ratios and their 95% confidence intervals from logistic regression analyses. Results Totals of 1042 males and 1547 females in urban areas, and 822 males and 1055 females in rural areas were included in the study. Overall, 53.1% of urban and 56.8% of rural respondents utilized health facilities past 12 months. In urban areas, significantly more females than males utilized health facilities (OR=1.4 (95% CI [1.1, 1.6]. Higher educational attainment (10+ years of schooling was associated with utilization of health facilities in both urban (OR=1.7, 95% CI [1.3, 2.1] and rural (OR=1.4, 95% CI [1.0, 2.0] areas compared to respondents who attained up to 7 years of schooling. Respondents who self-rated their health status as very poor/ poor/fair were twice more likely to utilize health facilities compared to those who rated their health as good/excellent. Respondents who reported illnesses were about three times more likely to utilize health facilities compared to those who did not report the illnesses. In urban areas, respondents who had mental distress were 1.7 times more likely to utilize health facilities compare to those who had no mental distress. Compared to respondents who were HIV negative, respondents who were HIV positive were 1.3 times more likely to utilize health facilities. Conclusion The health care needs were the factors most

  10. Socioeconomic issues and public involvement practices for near surface disposal of low and intermediate level radioactive waste - Indian approach

    International Nuclear Information System (INIS)

    Currently there are seven operating Near Surface Disposal Facilities (NSDFs) for low and intermediate level radioactive waste in India designed and constructed to address widely varying geological and climatic conditions. It is recognized that a broad range of socioeconomic and environmental issues arise during the repository life cycle. During the various stages of approval, committees representing a range of local community interests and the stakeholders (e.g. local government, schools, business, environmental groups, media etc) are involved. In view of the vastness of the country and the fact that nuclear reactors in India are located all over the country, the logistics for the safe transportation of radioactive waste dictates that the NSDFs are co-located with the reactor sites. In Indian context, the following aspects are considered for public acceptance: association, exhibitions, interaction with educational institutions, media relations, public awareness, printed information, and political influence. The reasons for the successful Indian experience are provided. (author)

    In August 2006, toxic wastes were discharged in the district of Abidjan, causing important health consequences in many households in the area. In order to appreciate the socio-economic impact of the consequences of toxic waste discharge on the households and of the measures taken by the authorities to deal with this catastrophe, and to appreciate the spatial extent of the pollution, we undertook a multidisciplinary transversal investigation at the sites of discharge of oxic waste, from October the 19th to December the 8th, 2006, using a transect sampling methodology. This paper presents the results related to the socio-economic aspects of the survey while the environmental and epidemiological results are presented in two other published papers. The socioeconomics investigation, conducted using a questionnaire, concerned 809 households across the various sites of discharge of toxic waste. More than 62% of households had at least one person who had been affected by toxic waste (affected households). 62.47% of these households were in Cocody district (with 2 sites and 4 points of discharge), 30.14% in Abobo district (with 2 sites and 3 points) and 7.39% in Koumassi district (with 1 site and 1 point). To escape the bad smell and the nuisance, 22.75% of the 501 "affected" households had left their houses. To face the health consequences generated by the toxic waste, 30.54% of the "affected" households engaged expenses. Those were on average of 92 450 FCFA (€141), with a minimum of 1 000 FCFA (€1.5) and a maximum of 1500000 FCFA (€2.287), in spite of the advertisement of the exemption from payment treatment fees made by the government. The decision of destroying cultures and farms near the points of discharge of the toxic products in a radius of 200 meters, taken by the authorities, touched 2.22% of the households. For these households, it did nothing but worsen their state of poverty, since the zone of influence of the toxic waste went well beyond the 200 meters

    Lower levels of academic achievement amongst children of lower SES have long interested researchers. Influences of SES are often addressed by studying predictors of achievement in economically advantaged and disadvantaged samples. Levels of engagement in school, argued to contribute to academic achievement independently of intelligence, have been found to be relatively lower amongst children from low SES families. Low SES is thus argued to have a destructive influence on engagement and achiev...

    Full Text Available The current crisis has shown that an economic integration through a political and monetary approach is wrong. It seems to be more appropriate a social and economic approach, meaning both a betterpreparedness of the new countries joining the euro area and more flexibility of the economic structures of the old members of the euro zone, in order to make the more "harmonious" the way of the monetary area operation. For that purpose, this article has made an analysis of the imbalances management issue in the euro area in order to provide a few theoretical solutions for a better functioning of the Economic and Monetary Union (EMU, based on the observation of developments in the euro area countries. This paper enriches theeconomic literature, but also it is relying on the research workings made by the authors in the field of European integration. The originality of this article arises from the extremely topical issue examined and its way of approach, but also from the conclusions outlined.

    The old reservoir areas built in 1950s-1970s left behind many socio-economic problems, because of the administrative backward migration and little migration fund, and all these problems would be tied to land. Based on interviewing with peasant households, combining land use survey and socio-economic statistical index, this paper analyzed land use change and its corresponding driving forces in Linshui reservoir area of Dahonghe Reservoir. Results showed that land use change in the reservoir area was mainly embodied on low-lying land submergence and migration requisition land. The former changed the land use patterns, and the latter mainly reconstructed original land property and made land over-fragmented. Cultivated land per capita was 0.041ha in this area, below the cordon of cultivated land per capita enacted by FAO. Currently, there were still 30.25% of peasant households being short of grain in trimester of one year, and there were 35.27% of people living under the poverty line. The conditions of eco-environment in Linshui Reservoir Area were worse, and healthy and sub-healthy eco-environment accounted for less proportion, composed of green belt around the reservoir area and paddy field ecosystem, and economic forest and orchard ecosystem, respectively. The stress of the reservoir project was macroscopic background to analyze the driving factors of land use change, and real underlying diving factor of the land use change in the area was the change of cultural landscape under the stress of reservoir project. The rapid increase of population was the key factor to induce the change of man-land relationship in the reservoir area, the low level of rural economy was the crucial factor to decide how migrants input for production, and the belief of migrants, influencing the land use patterns in a certain extent, was the inducing factor to keep land use stable. The low-lying submergence and infrastructure construction accompanied the reservoir project were leading

    International Nuclear Information System (INIS)

    A study on risk factors for type 2 diabetes and cardiovascular disease (CVD) in 250 male and female adult subjects 20 years of age and over, pertaining to different socio-economic levels is being conducted in Hermosillo, Sonora, Mexico. Measurements of weight, height, waist/hip ratio, blood pressure, oral glucose tolerance test, blood levels of total of cholesterol, tryglicerides, LDL and HDL-cholesterol are being obtained. Body composition is being determined by deuterium dilution and infrared spectroscopy, air displacement plethysmography, skinfold thickness and bio-electrical impedance. Physical activity by questionnaire and diet by non-consecutive multiple 24 h recalls (to account for seasonal and inter-individual variability), will provide information on lifestyle and diet. At present, analysis of 141 subjects has been completed. Preliminary results showed high levels of overweight, 55% with BMI>25, and obesity, 17% with BMI>30. Subjects with abnormal glucose levels had significantly higher weight (p<0.008), larger waist/hip ratio (p<0.003), higher % body fat (p<0.01), higher systolic and diastolic blood pressure (p<0.01; p<0.009 respectively) than normal subjects, after adjusting for sex and age. Serum tryglicerides were significantly higher in obese subjects with central adiposity than non-obese subjects. Body composition by deuterium dilution was determined by infrared spectroscopy and by air displacement plethysmography in a preliminary pilot study. Finally, a physical activity questionnaire was tested in two groups of subjects with different lifestyles. (author)

    Plasma zinc and copper status of 1689 non pregnant Tunisian women, aged 20-49 years old, was determined by flame atomic absorption spectrometry. A multiple regression was run to predict plasma trace element concentrations from age, BMI, marital status, menopause, education level, professional activity, economic level and area of living. The mean zinc and copper values were similar to those measured among comparable populations in earlier studies. However, a high prevalence of low plasma zinc and copper concentrations was observed assuming that women at childbearing age are at high risk of zinc and copper deficiencies and specific intervention may be considered. In univariate analysis, the mean values of plasma zinc and copper were associated with sitting areas and professional activity. For only plasma copper levels, there was an increase with BMI and parity, and a decrease with increasing schooling level and economic score. After adjustment for all variables, profession and parity showed a significant relationship between plasma levels copper. PMID:26859607

    Living in Low-lying areas is a challenging task, but due to the lack of suitable land at affordable prices, thousands of householders have been establishing their own houses on Low-lying areas. Manipulation and conversion of low lying areas have led to an increase in the frequency and severity of micro disasters because the cumulative effect of these settlements is very high. Therefore, it is needed to examine how individual households have been emerging in Low-lying areas. This process is primarily influenced and controlled by Socio-economic factors. In the field survey conducted for this study, 388 householders were interviewed face to face to obtain the primary data. Collected data were applied to the Multivariate binary logistic Model. The Dependent variable of the model was set as Stable Houses and Non-Stable Houses based on the weighted values that were obtained from the field observations. Independent variables of this study are nine key aspects of the socio-economic conditions in these areas. Units of analysis of the study were taken as individual housing plots in the study area. The particular combination of Socio-Economic factors that exerted influence on each housing plot was measured using predicted probability value of logistic model and linked it with GIS land plot's map. Accuracy of Final Model is 86.9 % and probability level of influencing factors given a clear idea about household distribution and status while providing guidance about how the planning authorities should monitor and manage low lying areas, taking into consideration the present housing condition of these areas.

  18. Integration of data from censuses and remote sensing to measure the socio-economic and environmental evolution in urban areas: case of the city of Sherbrooke (1981-2006)

    Dari, Ouassini

    The urban environment is complex, heterogeneous and temporally changeable. Man is the main actor in the transformation of urban areas where he interacts with intensity. Spatial differentiation is a result of human occupation in the urban environment. This occupation may vary according to land use, population density, social and economic characteristics and environment. This leads us to say that the socio-economic and environmental indicators change according to the various locations in the urban area and through time. Our goal is to measure the socio-economic and environmental changes in the urban area of the city of Sherbrooke using remote sensing data synchronized with the censuses and that we will then integrate into the geographic information system (GIS). We have used data from the 1981 and 2006 censuses, 1983 aerial photos, 2007 orthophotos and 1983 MSS and 2006 Ikons satellite images to measure the socio-economic and environmental changes in the city of Sherbrooke. We have used spatial analysis tools to integrate image data with census data. The methods uses such as global indices, principal component analysis combined with the variation between the two dates have yielded interesting results. The first factor in principal component analysis with orthogonal rotation (Varimax) justified a substantial percentage of the variance in global indices. The use of dissemination areas resulted in detailed information on the change in the city. From the perspective of spatial distribution, we noted a major difference between the central areas and the peripheral areas in 1981 and 2006. From the perspective of evolution between 1981 and 2006, we observed that are positive and negative changes at various levels took place. We also observed the evolution of ethnicity in the Sherbrooke city and Lennoxville municipality. The study showed that the French population is prevalent in the old city of Sherbrooke as the English population is prevalent in Lennoxville. The European

  1. Effects of socioeconomic status on brain development, and how cognitive neuroscience may contribute to leveling the playing field

    Full Text Available The study of socioeconomic status (SES and the brain finds itself in a circumstance unusual for Cognitive Neuroscience: large numbers of questions with both practical and scientific importance exist, but they are currently under-researched and ripe for investigation. This review aims to highlight these questions, to outline their potential significance, and to suggest routes by which they might be approached. Although remarkably few neural studies have been carried out so far, there exists a large literature of previous behavioural work. This behavioural research provides an invaluable guide for future neuroimaging work, but also poses an important challenge for it: how can we ensure that the neural data contributes predictive or diagnostic power over and above what can be derived from behaviour alone? We discuss some of the open mechanistic questions which Cognitive Neuroscience may have the power to illuminate, spanning areas including language, numerical cognition, stress, memory, and social influences on learning. These questions have obvious practical and societal significance, but they also bear directly on a set of longstanding questions in basic science: what are the environmental and neural factors which affect the acquisition and retention of declarative and nondeclarative skills? Perhaps the best opportunity for practical and theoretical interests to converge is in the study of interventions. Many interventions aimed at improving the cognitive development of low SES children are currently underway, but almost all are operating without either input from, or study by, the Cognitive Neuroscience community. Given that longitudinal intervention studies are very hard to set up, but can, with proper designs, be ideal tests of causal mechanisms, this area promises exciting opportunities for future research.

    Full Text Available This study analyzes the performance profile of Chilean city-school students from different socioeconomic strata, in relation to different sets of cognitive abilities specified in the curriculum framework for mathematics education in their country. The study is correlational and ex post facto in type, derived from the results of the math test of the System for Measuring Educational Quality (SIMCE applied to second-semester students of the 2001 school year. The percentage of students at each performance level was calculated, based on each student’s probability of correctly answering each of the test questions, using logistic function, associated with the two-parameter model of the Item Response Theory (IRT. The results show that regardless of the set of cognitive abilities in question, the performance profile follows a similar pattern. It was found that in general, there is a linear decrease in the percentage of those who achieve superior performances among students from low and medium-low strata, and exponential increases for middle-class students.

  6. Risk factors for type 2 diabetes and cardiovascular disease in Mexican adults from different socio-economic levels

    International Nuclear Information System (INIS)

    Background: Obesity, type 2 diabetes and cardiovascular disease (CVD) are a major concern in many parts of the world. In Northern Mexico, these problems have been reported to be higher the in the rest of the country. Objective: To assess the different risk factors based on body status (body composition, body size, fat distribution) and lifestyle factors (diet and physical activity) for the development of type 2 diabetes and CVD in men and women from different socio-economic levels in north-west Mexico. Methods: Non probabilistic sample selection by invitation was used to recruit subjects, completing quotas by age groups, gender and socio-economic status. The study included 350 men and women, 20-84 years pertaining to low and high income groups from the city of Hermosillo, Sonora, Mexico. All subjects were measured for body weight, height, waist and hip circumferences, skinfolds, bioimpedance analysis (BIA), systolic and diastolic blood pressure SBP, DBP). Body mass index (BMI) and waist to hip ratio were calculated. An oral glucose tolerance test (OGTT) after a 12 hour fast was performed and blood samples were taken for analysis of insulin, leptin, total cholesterol, HDL, LDL-cholesterol and serum triglycerides. In 273 of the 350 subjects physical activity was studied by questionnaire. Activity was calculated as in categories of low, medium and high intensity and expressed as hours/day with respect to occupational and recreational activities. Physical activity level (PAL) was also calculated from the questionnaires. Body composition was investigated in more detail by air displacement plethysmography (densitometry) and by deuterium dilution in 200 subjects. Diet by 24 hour non-consecutive recalls in another sub-group of 135 male and female subjects. Statistical analysis was performed using NCSS statistical software using ANCOVA and regression procedures. Result: High levels of overweight (BMI >25) and obesity BMI>30) were found in this population group with 65 and

    The Systems Development Report represents the third major step in the Clark County Socioeconomic Impact Assessment of the Proposed High-Level Nuclear Waste Repository at Yucca Mound Nevada. The first of these steps was to forge a Research Design that would serve as a guide for the overall research process. The second step was the construction of the Base Case, the purpose of which was to describe existing conditions in Clark County in the specified analytic areas of Economic-Demographic/Fiscal, Emergency Planning and Management, Transportation and Sociocultural analysis. The base case description will serve as a basis for assessing changes in these topic areas that might result from the Yucca Mountain project. These changes will be assessed by analyzing conditions with and without repository development in the county. Prior to performing such assessments, however, the snapshot type of data found in the base case must be operationalized or systematized to allow for more dynamic data utilization. In other words, a data system that can be used to analyze the consequences of the introduction of different variables (or variable values) in the Clark County context must be constructed. Such a system must be capable of being updated through subsequent data collection and monitoring efforts to both provide a rolling base case and supply information necessary to construct trend analyses. For example, during the Impact Assessment phase of the study process, the without repository analysis is accomplished by analyzing growth for the county given existing conditions and likely trends. These data are then compared to the with Yucca Mountain project conditions anticipated for the county. Similarly, once the emergency planning management and response needs associated with the repository are described, these needs will be juxtaposed against existing (and various future) capacity(ies) in order to determine the nature and magnitude of impacts in this analytic area.

    Full Text Available Background: Psychosocial stress is one important risk factor for myocardial infarction. Aim: The study was to assess the impact of the 2008-2009 economic recession on myocardial infarction occurrences in different socioeconomic areas of Raritan Bay region, New Jersey. Materials and Methods: The patients, who were treated for acute myocardial infarction from January 2006 to June 2012, were grouped based on the average incomes of their residence districts in the Raritan Bay region. The Spearman Rank Correlation test was used to assess the correlation between the monthly occurrences of myocardial infarction and Dow Jones stock averages, as well as the correlation between the myocardial infarction occurrences and NJ State unemployment rates. Results: Among 1,491 cases that were identified, 990 cases resided in areas with income below the state average and 477 were from areas above the average. After the onset of the recession, the myocardial infarction occurrences trended up in the low-income area group but not in the high-income area group; and this increasing trend is correlated with the rise in NJ State unemployment rates but not with the changes in stock averages. Conclusion: Our findings suggest that unemployment contributed to an increased risk of myocardial infarction among the residents in low socioeconomic areas after the 2008-2009 economic recession.

  10. A dwelling-level investigation into the physical and socio-economic drivers of domestic energy consumption in England

    International Nuclear Information System (INIS)

    The UK Government's Department for Energy and Climate Change has been investigating the feasibility of developing a national energy efficiency data framework covering both domestic and non-domestic buildings. Working closely with the Energy Saving Trust and energy suppliers, the aim is to develop a data framework to monitor changes in energy efficiency, develop and evaluate programmes and improve information available to consumers. Key applications of the framework are to understand trends in built stock energy use, identify drivers and evaluate the success of different policies. For energy suppliers, it could identify what energy uses are growing, in which sectors and why. This would help with market segmentation and the design of products. For building professionals, it could supplement energy audits and modelling of end-use consumption with real data and support the generation of accurate and comprehensive benchmarks. This paper critically examines the results of the first phase of work to construct a national energy efficiency data-framework for the domestic sector focusing on two specific issues: (a) drivers of domestic energy consumption in terms of the physical nature of the dwellings and socio-economic characteristics of occupants and (b) the impact of energy efficiency measures on energy consumption. - Highlights: • We examine the drivers of domestic energy consumption. • We examine the impact of domestic energy efficiency measures on energy use. • Dwelling type and size affect electricity and gas consumption. • Income level, tenure and number of resident adults influence energy use. • Energy efficiency measures lead to significant energy savings for households

    International Nuclear Information System (INIS)

    Data are analyzed on measurements of Rn levels in numerous U.S. homes, accompanied by responses to questionnaires. Substantial (but far from complete) bias reduction was accomplished using questionnaire responses, leaving 37,000 measurements in living areas and 33,000 in basements for the analysis. Variables studied included: level with respect to ground where measurement was made, room type, age of house, recent weatherization actions, draftiness, location (urban, suburban, rural), air pollution, market value of house, annual household income, educational attainment of head of household, cigarette smoking, whether the house is rented or owner occupied, and geographic section of U.S. Geometric mean Rn levels were determined for each response to questionnaire items (correlations) and for each pair of responses (cross correlations). Many interesting correlations and cross correlations were found, and their explanation and consequences are discussed

    Abstract Erosion caused in the coastal area of Togo especially in the cell to the east of the harbor of Lomé some reorganization of space and a reallocation of tasks functions of the importance of existing issues. This reorganization is an important race against time between the various stakeholders which paradoxically make this area a very dynamic environment. In spite of the disaster situation in the area, it is changing. This mutation has been observed for a decade in many ways. Fishing is a traditional activity disappears causing the emergence of new activities such as the extraction of gravel, the gardening, the informal trade of any kind, installing hotels, etc.. At the socio-economic transformation is associated with a beach in state of deficit causing the decline of the coastline that reaches approximately 500 m over a few kilometers according to the old marks missing. The decline of the coastline is by undermining the beach by the waves at high tide. These issues are reshaping the land use map that passes a distribution of fishing villages on the coast in 1980 to a suburban area exposed to sea level rise corollary to anticipated climate change.

    International Nuclear Information System (INIS)

    Specifically, the integration between social sciences and natural science are fundamental in our understanding of the economic, social and technological transformations that have drastically changed the society. This study will be based on the municipality of Sungai Petani, Kedah as it has been most influenced by urbanization and urban development. Urban development in Sungai Petani is closely associated with a tremendous increase in demand for land, which is highly related to population growth, human movement and their social mobility. The qualitative case study taken will rely on the visual interpretation technique that would allow the researcher to develop a map of urban changes detection. The potential application of GIS information to estimate socioeconomic indicators and the modelling of socio-economic activities that are explored in this study is hoped to increase further our understanding of the impacts of development and urbanization on social life

    Full Text Available Abstract Background This project is a community-level study of equity of access to eye health services for Indigenous Australians. Methods The project used data on eye health services from multiple sources including Medicare Australia, inpatient and outpatient data and the National Indigenous Eye Health Survey. The analysis focused on the extent to which access to eye health services varied at an area level according to the proportion of the population that was Indigenous (very low = 0-1.0%, low = 1.1-3.0%, low medium = 3.1-6.0%, high medium = 6.1-10.0%, high = 10.1-20.0%, very high = 20 + %. The analysis of health service utilisation also took into account age, remoteness and the Socioeconomic Indices for Areas (SEIFA. Results The rate of eye exams provided in areas with very high Indigenous populations was two-thirds of the rate of eye exams for areas with very low indigenous populations. The cataract surgery rates in areas with high medium to very high Indigenous populations were less than half that reference areas. In over a third of communities with very high Indigenous populations the cataract surgery rate fell below the World Health Organization (WHO guidelines compared to a cataract surgery rate of 3% in areas with very low Indigenous populations. Conclusions There remain serious disparities in access to eye health service in areas with high Indigenous populations. Addressing disparities requires a co-ordinated approach to improving Indigenous people’s access to eye health services. More extensive take-up of existing Medicare provisions is an important step in this process. Along with improving access to health services, community education concerning the importance of eye health and the effectiveness of treatment might reduce reluctance to seek help.

  18. Water levels in the Yucca Mountain Area, Nevada, 1996

    International Nuclear Information System (INIS)

    Water levels were monitored in 24 wells in the Yucca Mountain area, Nevada, during 1996. Twenty-two wells representing 28 depth intervals were monitored periodically, generally on a monthly basis, and 2 wells representing 3 depth intervals were monitored both hourly and periodically. All wells monitor water levels in Tertiary volcanic rocks except one that monitors water levels in paleozoic carbonate rocks. Water levels were measured using either calibrated steel tapes or a pressure sensor. Mean water-level altitudes in the Tertiary volcanic rocks ranged from about 727.86 to about 1,034.58 meters above sea level during 1996. The mean water-level altitude in the well monitoring the Paleozoic carbonate rocks was about 752.57 meters above sea level during 1996. Mean water-level altitudes for 1996 were an average of about 0.06 meter lower than 1995 mean water-level altitudes and 0.03 meter lower than 1985--95 mean water-level altitudes. During 1996, water levels in the Yucca Mountain area could have been affected by long-term pumping at the C-hole complex that began on May 8, 1996. Through December 31, 1996, approximately 196 million liters were pumped from well UE-25 c number-sign 3 at the C-hole complex.

Other ground-water pumpage in the Yucca Mountain area includes annual pumpage from water-supply wells UE-25 J-12 and UE-25 J-13 of approximately 163 and 105 million liters, respectively, and pumpage from well USW G-2 for hydraulic testing during February and April 1996 of approximately 6 million liters.

  20. Socioeconomic development as a determinant of the levels of organochlorine pesticides and PCBs in the inhabitants of Western and Central African countries

    International Nuclear Information System (INIS)

    Several studies of environmental samples indicate that the levels of many persistent organic pollutants (POPs) are increasing in Africa, but few studies have been conducted in humans. Simultaneously, many African countries are experiencing a rapid economic growth and implementing information and communication technologies (ICT). These changes have generated high amounts of electronic waste (e-waste) that have not been adequately managed. We tested the hypothesis that the current levels of two main classes of POPs in Western and Central African countries are affected by the degree of socioeconomic development. We measured the levels of 36 POPs in the serum of recent immigrants (N = 575) who came from 19 Sub-Saharan countries to the Canary Islands (Spain). We performed statistical analyses on their anthropometric and socioeconomic data. High median levels of POPs were found in the overall sample, with differences among the countries. Organochlorine pesticide (OCP) and polychlorinated biphenyl (PCB) levels increased with age. People from low-income countries had significantly higher OCP levels and much lower PCB levels than those from high-income countries. We found a significant association between the implementation of ICT and PCB contamination. Immigrants from the countries with a high volume of imports of second-hand electronic equipment had higher PCB levels. The economic development of Africa and the e-waste generation have directly affected the levels of POPs. The POP legacies of these African populations most likely are due to the inappropriate management of the POPs' residues. - Highlights: • Higher levels of organochlorine pesticides in Africans from low-income countries • Higher levels of PCBs in Africans from high-income countries • Levels of PCBs are significantly higher in people from West Africa. • Significant association between implementation of ICT and PCB contamination • High volume of second-hand electronic equipment is associated

    Full Text Available ABSTRACTINTRODUCTION:This study aimed to evaluate basic sanitation and socioeconomic indicators, reported cases of malaria, and risk of contracting malaria in the Ananindeua municipality, State of Pará.METHODS:Data on basic sanitation and socioeconomic dimensions were taken from the Brazilian Institute of Geography and Statistics [ Instituto Brasileiro de Geografia e Estatística (IBGE] 2010 census. Epidemiological malaria information was taken from the Epidemiological Malaria Surveillance Information System [ Sistema de Informação de Vigilância Epidemiológica de Malária (SIVEP/Malaria], between 2003 and 2013 of the Ministry of Health and from the SIVEP/Malaria forms of the municipality's Endemic Diseases Unit for 2,013 cases.RESULTS:Our data do not confirm the correlation among indicators of basic sanitation, socioeconomic conditions, and water supply with malaria cases. Of the 1,557 cases evaluated, most were caused by Plasmodium vivax , with rare cases of Plasmodium falciparum and mixed infections. There were 756 notifications in 2003. The number of reported cases was sharply reduced between 2006 and 2012, but a 142-case outbreak occurred in 2013. Ananindeua municipality's Annual Parasite Index indicated low risk in 2003 and no risk in other years, and the 2,013 cases were predominantly male individuals aged ≥40 years.CONCLUSIONS:Our data confirm the non-endemicity of malaria in the Ananindeua municipality, as the Annual Parasite Indices described for the years 2004-2013 classify it as a risk-free area. However, the 2013 outbreak indicates the need to strengthen prevention, surveillance, and control activities to reduce the risk of new outbreaks and consequent economic and social impacts on the population.

    Depression is the most common psychiatric co-morbidity among people living with HIV (PLHIV), with prevalence rates ranging from 25% to 36%. Depression impacts negatively upon adherence and response to combined antiretroviral therapy (CART) and the transmission of HIV infection through increased sexually risky behavior. This cross-sectional study presents data from a reference HIV-outpatient service in Dourados (Brazil) that evaluated the association between depressive symptoms, health-related quality of life, and clinical, socioeconomic, and demographic factors in newly diagnosed HIV/AIDS patients. Using the Beck Depression Inventory (BDI), the prevalence of depressive symptoms was 61% with a predominance of self-deprecating and cognitive-affective factors. Depressive symptoms were associated with lower income (p=0.019) and disadvantaged social class (p=0.005). Poorer quality of life was related to depressive symptoms (p<0.0001), low educational level (p=0.05), and lower income (p=0.03). These data suggest that socioeconomic factors, including level of income and education, are mediating the risk of depression and poor quality of life of PLHIV. Possible explanations for this effect are discussed, including the possible role of stigma. PMID:25741909

  4. Water levels in the Yucca Mountain area, Nevada, 1993

    International Nuclear Information System (INIS)

    Water levels were monitored in 28 wells in the Yucca Mountain area, Nevada, during 1993. Seventeen wells were monitored periodically, generally on a monthly basis, and 11 wells representing 18 intervals were monitored hourly. All wells monitor water levels in Tertiary volcanic rocks, except one that monitors water levels in Paleozoic carbonate rocks. Water levels were measured using calibrated steel tapes and pressure transducers; steel-tape measurements were corrected for mechanical stretch, thermal expansion, and borehole deviation to obtain precise water-level altitudes. Water-level altitudes in the Tertiary volcanic rocks ranged from about 728 meters above sea level east of Yucca Mountain to about 1,034 meters above sea level north of Yucca Mountain. Water-level altitudes in the well monitoring the Paleozoic carbonate rocks varied between 752 and 753 meters above sea level during 1993. Water levels were an average of about 0.04 meter lower than 1992 water levels. All data were acquired in accordance with a quality-assurance program to support the reliability of the data

    Full Text Available Abstract Background Preterm birth is a complex disease with etiologic influences from a variety of social, environmental, hormonal, genetic, and other factors. The purpose of this study was to utilize a large population-based birth registry to estimate the independent effect of county-level poverty on preterm birth risk. To accomplish this, we used a multilevel logistic regression approach to account for multiple co-existent individual-level variables and county-level poverty rate. Methods Population-based study utilizing Missouri's birth certificate database (1989–1997. We conducted a multilevel logistic regression analysis to estimate the effect of county-level poverty on PTB risk. Of 634,994 births nested within 115 counties in Missouri, two levels were considered. Individual-level variables included demographics factors, prenatal care, health-related behavioral risk factors, and medical risk factors. The area-level variable included the percentage of the population within each county living below the poverty line (US census data, 1990. Counties were divided into quartiles of poverty; the first quartile (lowest rate of poverty was the reference group. Results PTB th quartile (4.9%, p adjOR 1.18 (95% CI 1.03, 1.35, with a similar effect at earlier gestational ages (adjOR 1.27 (95% CI 1.06, 1.52. Conclusion Women residing in socioeconomically deprived areas are at increased risk of preterm birth, above other underlying risk factors. Although the risk increase is modest, it affects a large number of pregnancies.

    It has been four years since the Clean Air Act was amended in November of 1990. Much work has been done in this time, and the country is beginning to see real air quality benefits. Although these changes have not completely licked the urban ozone problem yet, they have made a lot of progress. All of the urban areas which have been required to reduce their ozone levels have done a good job of lowering their emissions. While the urban areas have not all been able to meet every federal deadline, the areas have all been able to achieve the control milestones before the mandatory Clean Air Act sanctions have taken effect. Some areas are even ready to declare their ozone problems solved.

    There is a great variability in licit prescription drug use in the population and among patients. Factors other than purely medical ones have proven to be of importance for the prescribing of licit drugs. For example, individuals with a high age, female gender and low socioeconomic status are more...... likely to use licit prescription drugs. However, these results have not been adjusted for multi-morbidity level. In this study we investigate the odds of using licit prescription drugs among individuals in the population and the rate of licit prescription drug use among patients depending on gender, age...

    2015-01-01

    Onchocerciasis is a severe parasitic infestation caused by Onchocerca volvulus which causes disabling skin and subcutaneous tissue changes and ultimately leads to blindness. It has a huge public health impact due to its socioeconomic burden and the vast number of people it affects in developing countries. In this case, a 60 years old woman was encountered with leopard skin like changes, rashes and pruritus on the left leg; which had been managed as cutaneous mycosis for over a period of 8 years. A diagnosis of onchocerciasis was finally made after a skin snip identified onchocercal microfilariae. The above case shows that onchocerciasis is still a neglected tropical disease (NTD) in Cameroon. This emphasizes the need for more expansive outreach programs in remote areas in Cameroon, a change in health policies to ensure the eradication of this disabling disease and health promotion amongst vulnerable populations.

  17. Socioeconomic status and patterns of care in lung cancer

    International Nuclear Information System (INIS)

    This retrospective study aims to explore any associations between socioeconomic factors and lung cancer management and outcome in the Australian setting. The study population consisted of patients newly diagnosed with lung cancer in 1996 who were living in the Northern Sydney Area Health Service (NSAHS) or South Western Sydney Area Health Service (SWSAHS). These two Area Health Services differ in socioeconomic profiles based on socioeconomic indexes for areas (SEIFA), median income, education level and unemployment rate. Data on patient demographics, tumour characteristics, management details, recurrence and survival were collected, and the patterns of care were analysed. Socioeconomic status indicators of the two Area Health Services were imputed from the Australian Bureau of Statistics data. There were 270 and 256 new cases of lung cancer identified in NSAHS and SWSAHS respectively. Patients in NSAHS were slightly older (median age 73 versus 68 years) and there was less male predominance. The stage distributions and performance status of the two cohorts were similar. There were no significant differences in the utilisation rates of different treatment modalities between the two areas: radiotherapy (54% in NSAHS and 55% in SWSAHS), chemotherapy (34% and 25%), surgery (26% and 21%) and no treatment (22% and 25%). The 5-year overall survival was slightly in favour of NSAHS (10.5% and 7.4%), but did not reach statistical significance. Despite differences in socioeconomic profiles between the two area health services, patients with lung cancer had similar patterns of care and survival

    Full Text Available Objetivo: Valorar si dos indicadores socioeconómicos (uno simple y otro compuesto elaborados en el ámbito de sección censal permiten detectar desigualdades sociales en salud. Métodos: De la Encuesta de Salud de Barcelona de 1992 (ESB92 se han considerado el estado de salud percibido, la presencia de trastornos crónicos, el consumo de tabaco y la realización de una citología cervical preventiva, así como el nivel de estudios y la clase social. A partir del censo de 1991, como indicadores socioeconómicos de área se han calculado el porcentaje de desempleo y un índice de privación en las secciones censales. Se analiza la asociación entre las medidas socioeconómicas de área e individuales y la asociación de ambas con las variables de salud. Resultados: Existe una clara asociación positiva entre las medidas socioeconómicas de área pequeña y las individuales y, en general, con ambas se han observado similares efectos en diversos aspectos relacionados con la salud, tanto en varones como en mujeres. Con la mayoría de las variables analizadas, las diferencias son superiores con el índice de privación que con el desempleo.

    This study investigated the association between individual and area socioeconomic status (SES) and leading causes of unintentional injury mortality in Canadian adults. Using the 1991-2001 Canadian Census Mortality Follow-up Study cohort (N=2,735,152), Cox proportional hazard regression was used to calculate hazard ratios and 95% confidence intervals for all-cause unintentional injury, motor vehicle collision (MVC), fall, poisoning, suffocation, fire/burn, and drowning deaths. Results indicated that associations with SES differed by cause of injury, and were generally more pronounced for males. Low education was associated with an elevated risk of mortality from all-cause unintentional injury and MVC (males only) and poisoning and drowning (both sexes). Low income was strongly associated with most causes of injury mortality, particularly fire/burn and poisoning. Having no occupation or low occupational status was associated with higher risks of all-cause injury, fall, poisoning and suffocation (both sexes) and MVC deaths among men. Associations with area deprivation were weak, and only areas with high deprivation had elevated risk of all-cause injury, MVC (males only), poisoning and drowning (both sexes). This study reveals the importance of examining SES differentials by cause of death from a multilevel perspective. Future research is needed to clarify the mechanisms underlying these differences to implement equity-oriented approaches for reducing differential exposures, vulnerability or consequences of injury mortality.

  4. Dose Area Product reference levels in dental panoramic radiology

    International Nuclear Information System (INIS)

    The purpose of this study was to measure DAP (Dose Area Product) values in panoramic radiology with the use of a DAP meter, to determine corresponding reference levels, and to compare DAP between panoramic and intraoral radiology. DAP was measured in 62 panoramic X-ray units for 3 types of exposure (male, female and child) and in 20 intraoral X-ray units of 50, 60 and 70 kVp. DAP reference levels were 117 mGy cm2, 97 mGy cm2 and 77 mGy cm2 for exposure of a male, female and child respectively. Results showed that DAP from a panoramic dental examination is approximately twice that from a single intraoral examination. DAP meter is a very convenient and easy to use tool for patient dosimetry and for the establishment of reference levels in dental panoramic radiology. (authors)

    Full Text Available Customer satisfaction index models have been developed in many countries, including Indonesia. Those models were commonly not focused on the socioeconomic status (SES of the customer, sothis condition could be a research gap. The aims of this research is to analyze the customer satisfaction index model of branded cooking oil product in Bogor, Indonesia based on SES established from the household monthly routine consumption. Questionnaires were used as primary data collection instrument in this study, while data analysis was carried out with variance based structural equation modeling (SEM which is also known as Partial Least Square (PLS model, and Kruskall Wallis nonparametric test. Perceived quality, perceived value and customer expectation as were significantly influencing the customer satisfaction construct in the structural model. This study also concluded that there is different level of overall customer satisfaction on the three levels of customer’s SES

  8. Socio-economic impact

    International Nuclear Information System (INIS)

    The construction of an electric generating station may have socio-economic effects upon the community in which it is located. Among the possible effects during construction are changes in population leading to strains in housing, schools, employment, transportation, and increased demands on local government services. The scale of the effects varies according to the population base of the county in which the plant is located and the distance of the site from major metropolitan areas. Increased demands for county and municipal public services also vary during the construction period. In some instances the increased cost of public services can result in large budget deficits at both the county and municipal level as construction period revenue increases fail to keep pace with service costs. In the study case of potential Eastern Shore power plant sites, annual municipal budget deficits were estimated to range from 3 to 21% for nuclear plant construction. The same study projected the largest county deficit at 4%, with other counties experiencing revenues and expenditures which were essentially in balance. After a new plant starts operation, the tax revenue to county government is on the order of several million dollars per year or greater depending on plant size and local tax rates, and the service costs are small

    Nuclear-generated electricity supplies almost 40% of the demand in Switzerland (the rest being hydro-power). Allowing for a certain reserve and assuming an operational life-time of 40 years for each reactor, and taking into account wastes from decommissioning and from medicine, industry and research, the total amount of low-level radioactive waste to be disposed of is about 175,000 m{sup 3}. Since there are no unpopulated areas in Switzerland, and since Swiss Federal Law specifies that the safety of disposal may not depend upon supervision of the repository, no shallow-land burial has been foreseen, even for short-lived low-level waste. Instead, geological disposal in a mined cavern system with access through a horizontal tunnel was selected as the best way of meeting the requirements and ensuring the necessary public acceptance.

Furthermore, organic farming in this low-yield area tends to be economically attractive for farmers due to political support and low foregone income from conventional farming. However, the indirect...... shows that in addition to geography, agriculture is one major determinant of biodiversity status.

    1989-05-01

    The study was carried out in the municipality of Aarhus, a city of 250,000 inhabitants. The study was designed as a cross-sectional cohort study of school children in first grade in 1982-83. A total of 2,412 children were contacted and asked to submit their shed teeth to the teacher, and 1,291 children delivered at least one usable tooth (response rate, 54 percent). The lead level in circumpulpal dentin showed an average of 10.7 micrograms/g. Eight percent of the children (N = 110) had a lead level above 18.7 micrograms/g and were selected as a high lead exposure group. This group was matched by sex and socio-economic status of the parents with control children with a dentin lead level below 5 micrograms/g. Following a detailed interview with the parents, children were excluded from the study if medical risk factors were present. A clinical psychologist, blind to the lead data, administered selected psychometric tests to 162 of the children selected. The high-lead children scored lower on the WISC when compared to low-lead children, especially on the Verbal IQ (p less than 0.001) and Full Scale IQ (p less than 0.01). No significant difference was seen between the high- and low-exposure groups on the Performance IQ and on several experimental tests. Impaired function associated with lead exposure was also found on the Bender Visual Motor Gestalt Test (p less than 0.001) and on a behavioral rating scale (p less than 0.01). These results remained statistically significant even after controlling for socio-economic status and other confounding variables.

  13. Environmental and socioeconomic impacts of utilizing waste for biochar in rural areas in Indonesia--a systems perspective.

    Biochar is the product of incomplete combustion (pyrolysis) of organic material. In rural areas, it can be used as a soil amendment to increase soil fertility. Fuel-constrained villagers may however prefer to use biochar briquettes as a higher-value fuel for cooking over applying it to soils. A systems-oriented analysis using life cycle assessment (LCA) and cost benefit analysis (CBA) was conducted to analyze these two alternative uses of biochar, applying the study to a rural village system in Indonesia. The results showed soil amendment for enhanced agricultural production to be the preferential choice with a positive benefit to the baseline scenario of -26 ecopoints (LCA) and -173 USD (CBA) annually pr. household. In this case, the positive effects of carbon sequestration to the soil and the economic value of the increased agricultural production outweighed the negative environmental impacts from biochar production and the related production costs. Use of biochar in briquettes for cooking fuel yielded negative net effects in both the LCA and CBA (85 ecopoints and 176 USD), even when positive health effects from reduced indoor air pollution were included. The main reasons for this are that emissions during biochar production are not compensated by carbon sequestration and that briquette making is labor-intensive. The results emphasize the importance of investigating and documenting the carbon storage effect and the agricultural benefit in biochar production-utilization systems for a sustainable use. Further research focus on efficient production is necessary due to the large environmental impact of biochar production. In addition, biochar should continue to be used in those soils where the agricultural effect is most beneficial. PMID:24678863

    This study investigated whether the availability and accessibility of supermarkets and fruit and vegetable stores, and the availability, variety and price of foods within these stores, varied across areas of different levels of socioeconomic disadvantage in Melbourne, Australia. Data on food store locations, and food variety and price within stores were obtained through objective audits of 45 neighbourhoods of varying socioeconomic disadvantage. Geographical accessibility of healthy food stores was mostly better amongst those living in more advantaged neighbourhoods. Availability of healthy foods within stores only slightly favoured those in advantaged neighbourhoods. However food prices favoured those living in disadvantaged areas. PMID:19046654

    Objective To examine the influence of neighbourhood socioeconomic position (NSEP) on development of diabetes over time. Design A longitudinal cohort study. Setting The data reported were from the Sacramento Area Latino Study on Aging, a longitudinal study of the health of 1789 older Latinos. Participants Community-dwelling older Mexican Americans residing in the Sacramento Metropolitan Statistical Area. Main outcome Multistate Markov regression were used to model transitions through four possible states over time: 1=normal; 2=pre-diabetic; 3=diabetic; and 4=death without diabetes. Results At baseline, nearly 50% were non-diabetic, 17.5% were pre-diabetic and nearly 33% were diabetic. At the end of follow-up, there were a total of 824 people with type 2 diabetes. In a fully adjusted MSM regression model, among non-diabetics, higher NSEP was not associated with a transition to pre-diabetes. Among non-diabetics, higher NSEP was associated with an increased risk of diabetes (HR=1.66, 95% CI 1.14 to 2.42) and decreased risk of death without diabetes (HR: 0.56, 95% CI 0.33 to 0.96). Among pre-diabetics, higher NSEP was significantly associated with a transition to non-diabetic status (HR: 1.22, 95% CI 0.99 to 1.50). Adjusting for BMI, age, education, physical activity, smoking, alcohol consumption, medical insurance and nativity did not affect this relationship. Conclusions Our findings show that high NSEP poses higher risk of progression from normal to diabetes compared with a lower risk of death without diabetes. This work presents a possibility that these associations are modified by nativity or culture. PMID:27515749

  1. The relation of equity issues to risk perceptions and socioeconomic impacts of a high level waste repository

    International Nuclear Information System (INIS)

    This paper discusses how equity concerns are an important component of the debater on controversial public policy decisions such as those regarding high-level waste disposal. In science policy, concepts of fairness need to be applied to what counts as evidence, as well as to process (means) and outcomes (ends). A science policy decision that involves technologies perceived as risky may have a better chance of enduring over time if all the key parties feel that they have been fairly treated. One task of risk communication is to engage in a dialogue with affected parties and the public about what is fair in terms of process, evidence, and outcomes

  2. Closing the gap between socioeconomic and financial implications of residential and community level hydrogen-based energy systems: Incentives needed for a bridge to the future

    Verduzco, Laura E.

    The use of hydrogen as an energy carrier has the potential to decrease the amount of pollutants emitted to the atmosphere, significantly reduce our dependence on imported oil and resolve geopolitical issues related to energy consumption. The current status of hydrogen technology makes it prohibitive and financially risky for most investors to commit the money required for large-scale hydrogen production. Therefore, alternative strategies such as small and medium-scale hydrogen applications should be implemented during the early stages of the transition to the hydrogen economy in order to test potential markets and technology readiness. While many analysis tools have been built to estimate the requirements of the transition to a hydrogen economy, few have focused on small and medium-scale hydrogen production and none has paired financial with socioeconomic costs at the residential level. The computer-based tool (H2POWER) presented in this study calculates the capacity, cost and socioeconomic impact of the systems needed to meet the energy demands of a home or a community using home and neighborhood refueling units, which are systems that can provide electricity and heat to meet the energy demands of either (1) a home and automobile or (2) a cluster of homes and a number of automobiles. The financial costs of the production, processing and delivery sub-systems that conform the refueling units are calculated using cost data of existing technology and normalizing them to calculate capital and net present cost. The monetary value of the externalities (socioeconomic analysis) caused by each system is calculated by H2POWER through a statistical analysis of the cost associated to various externalities. Additionally, H2POWER calculates the financial impact of different penalties and incentives (such as net metering, low interest loans, fuel taxes, and emission penalties) on the cost of the system from the point of view of a developer and a homeowner. In order to assess the

  3. Household dust metal levels in The Sao Paulo metropolitan area

    International Nuclear Information System (INIS)

    A study about household dust is being conducted to determine the level of metal contamination in the Sao Paulo Metropolitan Area (SPMA). The SPMA, with 18 million inhabitants, is one of the largest urban areas of the world, with serious environmental problems, due to the great amount of industries, heavy traffic and the disordered growth of population. The pollutants originate from a multiplicity of indoor and outdoor sources. Indoor sources are originated from residual (hair, skin scales), pets, human activities, construction materials, and furnishings as well as biological material (pollen, insect parts).and outdoor pollution, usually from the urban traffic. The pollutant mixture involved in numerous physical and chemical processes and changes its characteristics with time. Its composition and concentration depend on the strengths of indoor sources, the concentration of pollutants outside and the properties of ventilation and air-conditioning systems. It is well recognized that many metals have chronic effects on humans, in particular toddlers, who are at an higher risk compared to adults because they engage in greater hand to-mouth activity and their neurological systems are still developing. The household dust samples were collected from different localities, using vacuum cleaner, and sieved up to particle size -1; Mn, 119-369 μg g-1; Fe, 372-1464 μg g-1; Ni, 33-85 μg g-1; Cu, 42-303 μg g-1; Zn, 156-1369 μg g-1 and Pb, 26-160 μg g-1.

    Full Text Available Effective conservation depends largely on people's compliance with regulations. We investigate compliance through the lens of fishers' compliance with marine protected areas (MPAs. MPAs are widely used tools for marine conservation and fisheries management. Studies show that compliance alone is a strong predictor of fish biomass within MPAs. Hence, fishers' compliance is critical for MPA effectiveness. However, there are few empirical studies showing what factors influence fishers' compliance with MPAs. Without such information, conservation planners and managers have limited opportunities to provide effective interventions. By studying 12 MPAs in a developing country (Costa Rica, we demonstrate the role that different variables have on fishers' compliance with MPAs. Particularly, we found that compliance levels perceived by resource users were higher in MPAs (1 with multiple livelihoods, (2 where government efforts against illegal fishing were effective, (3 where fishing was allowed but regulated, (4 where people were more involved in decisions, and (5 that were smaller. We also provide a novel and practical measure of compliance: a compound variable formed by the number illegal fishers and their illegal fishing effort. Our study underlines the centrality of people's behavior in nature conservation and the importance of grounding decision making on the social and institutional realities of each location.

  5. An Exploratory Study of the Effects of Mindfulness on Perceived Levels of Stress among school-children from lower socioeconomic backgrounds.

    Full Text Available Children from lower socioeconomic backgrounds are at increased risk of experiencing stress and associated social-emotional difficulties and behavioural problems, which can undermine academic performance and lead to school drop-out. Previous studies investigating the effects of mindfulness have evidenced positive outcomes among children pertaining to enhanced well-being, school-based competence and decreased levels of stress and anxiety. However, these studies have typically examined teacher’s perceptions of change or quantitative outcomes without consideration of children’s experiences. The present study employs an interpretative qualitative approach to gain a greater understanding of children’s experiences of mindfulness in dealing with stress. A 5-week school-based mindfulness program was performed with 63 primary school children at risk of social exclusion in education. Interviews were undertaken with 16 children and 2 teachers. Thematic analysis identified five key themes labelled conceptualisation of stress, awareness, self-regulation, classroom regulations and addressing future stress. Quantitative measures of children’s perceived stress levels evaluated at baseline and follow-up also revealed significant reductions post intervention. These findings offer support for the incorporation of mindfulness interventions into the school curriculum, as a means of empowering children to address stress in their lives and improving full participation in the education system.

    Rapid urbanization and increasing urban poverty characterize much of Southern Africa, resulting in poor urban health. This study investigates inter-urban differences and determinants of undernutrition among marginalized communities. Using the 1992, 2000 and 2006/2007 Namibia Demographic and Health Survey data, we fitted hierarchical random intercept logit models, applied at 52 enumeration areas in the capital city (Windhoek), to estimate trends in undernutrition, and investigate risk factors associated with stunting and underweight. Findings demonstrate that undernutrition among children has risen (7.4% to 25.1%, p<0.001 for stunting; and 9.7% to 17.6%, p<0.001 for underweight, between 1992 and 2006/2007). The risk was pronounced for children from socioeconomically disadvantaged households (OR=1.53, 95% CI:[1.01, 2.31] for stunting and OR=2.16, 95% CI:[1.03, 4.89]for underweight). Evidence emerged of intra-urban variation in undernutrition. We argue that with increasing urbanization, comes the challenge of food insecurity and, consequently, malnutrition. For improved child health, urban planners should have targeted interventions for poor urban households and deprived neighbourhoods. PMID:27009767

  7. In situ rainwater harvesting using dead level contours in semi-arid southern Zimbabwe: Insights on the role of socio-economic factors on performance and effectiveness in Gwanda District

    Munamati, Muchaneta; Nyagumbo, Isaiah

    Droughts and dry spells which have characterised the past decade in Zimbabwe have seen a marked increase in the promotion and use of in situ rainwater harvesting technologies (RWHTs) as a drought mitigating strategy. A number of these technologies have been tried in recent years which include dead level contours with infiltration pits and deepened contours. Although in situ RWHTs are known to increase food security in drought prone areas, the role of socio-economic factors on their performance in terms of crop yield and scaling out is still not well understood. This study sought to investigate the socio-economic factors which influence the effectiveness of dead level contours for in situ rainwater harvesting and consequently on crop yield. The study involved 14 key informants interviews and questionnaire administration to a total of 55 respondent farmers practising in situ rainwater harvesting with dead level contours. A statistical package (Statistical Package for Social Scientists, SPSS) was used to analyse relationships between performance of RWHTs and attributes such as labour, resources, gender, experience and education. The results show a strong correlation between performance and resource status ( p = 0.004). For example, within the wealthy category, 42.1% were successful, while 14.3% and 13.8% were average and poor performers respectively. Thus within the successful category, 42.1% were wealthy, while 42.1% and 15.8% were medium-rich and resource-constrained respectively. Performance rating was also significantly correlated ( p = 0.007) to gender of household head e.g., within the most successful group 94.7% were men compared to 5.3% women. There was also a significant correlation between resource status and gender ( p = 0.039) such that within the wealthy category, 69.2% of the respondents were men compared to 30.8% women. Labour was found to have no significance on performance ( p > 0.05) even though the majority of key informants (93%) alluded that the

    Full Text Available Background: Adolescence, the transition from childhood to adulthood is an important crossroad. Studies are available which suggest that a considerable number of adolescent boys (16 to 14% and girls (1 to 10% engage in premarital sexual activity. All though importance of health education and health counseling for adolescents have been incorporated in the formal education system but there are no large scale community based studies to assess awareness level of adolescent girls about the method of family planning. The present study was undertaken to evaluate the effect of socio-economic factor on the awareness level of adolescent girls with special reference to the methods of family planning, and their concepts about long term effects of high population growth. Methods: The study samples were higher secondary girl students between 15 to 19 years of age in 5 rural schools (Hindi & English medium of Wardha district, Maharashtra, India. The survey programme was conducted during a period of one year from July 2011 to June 2012. A questionnaire was prepared in local language. Results: The education level of parent in upper-middle (group A was significantly more than low-economic group (group B. Knowledge about hormonal contraceptive pill in group A was significantly high than group B and the idea about surgical technique and condom was also high in group A than group B. Regarding emergency contraceptive technique, the idea in group A was high but in group B, the rate was very low. Conclusions: The awareness programme should be conducted in formal education in the school curricula so that adolescent girl’s knowledge, attitude and practice can be assessed.

  13. Final base case community analysis: Indian Springs, Nevada for the Clark County socioeconomic impact assessment of the proposed high- level nuclear waste repository at Yucca Mountain, Nevada

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    1992-06-18

    This document provides a base case description of the rural Clark County community of Indian Springs in anticipation of change associated with the proposed high-level nuclear waste repository at Yucca Mountain. As the community closest to the proposed site, Indian Springs may be seen by site characterization workers, as well as workers associated with later repository phases, as a logical place to live. This report develops and updates information relating to a broad spectrum of socioeconomic variables, thereby providing a `snapshot` or `base case` look at Indian Springs in early 1992. With this as a background, future repository-related developments may be analytically separated from changes brought about by other factors, thus allowing for the assessment of the magnitude of local changes associated with the proposed repository. Given the size of the community, changes that may be considered small in an absolute sense may have relatively large impacts at the local level. Indian Springs is, in many respects, a unique community and a community of contrasts. An unincorporated town, it is a small yet important enclave of workers on large federal projects and home to employees of small- scale businesses and services. It is a rural community, but it is also close to the urbanized Las Vega Valley. It is a desert community, but has good water resources. It is on flat terrain, but it is located within 20 miles of the tallest mountains in Nevada. It is a town in which various interest groups diverge on issues of local importance, but in a sense of community remains an important feature of life. Finally, it has a sociodemographic history of both surface transience and underlying stability. If local land becomes available, Indian Springs has some room for growth but must first consider the historical effects of growth on the town and its desired direction for the future.

  14. Final base case community analysis: Indian Springs, Nevada for the Clark County socioeconomic impact assessment of the proposed high- level nuclear waste repository at Yucca Mountain, Nevada

    International Nuclear Information System (INIS)

    This document provides a base case description of the rural Clark County community of Indian Springs in anticipation of change associated with the proposed high-level nuclear waste repository at Yucca Mountain. As the community closest to the proposed site, Indian Springs may be seen by site characterization workers, as well as workers associated with later repository phases, as a logical place to live. This report develops and updates information relating to a broad spectrum of socioeconomic variables, thereby providing a 'snapshot' or 'base case' look at Indian Springs in early 1992. With this as a background, future repository-related developments may be analytically separated from changes brought about by other factors, thus allowing for the assessment of the magnitude of local changes associated with the proposed repository. Given the size of the community, changes that may be considered small in an absolute sense may have relatively large impacts at the local level. Indian Springs is, in many respects, a unique community and a community of contrasts.

  15. Effects of socio-economic status on mortality: separating the nearby from the farther away

    OpenAIRE

    2005-01-01

    Socio-economic status effects on total and cause-specific mortality are studied using data on all 15.8 million inhabitants of the Netherlands in 1999. Two problems are addressed that often hamper this kind of research: the lack of reliable social status information at the individual level and the intermingling of individual and neighbourhood status effects. The first problem is dealt with by using socio-economic status information of the very close environment of the detailed postcode areas (...

    Full Text Available Unplanned and rapid urbanization, industrialization, increasing number of vehicles, poor traffic management, poor road condition etc. are the major causes of higher noise levels in most of the Indian cities. Prolonged exposure to higher noise levels can lead to irreversible Noise Induced Hearing Loss (NIHL. Noise-induced hearing loss is contributing one-third to the total persons suffering from hearing loss in every country in the world. The present study aims at measuring the noise levels in the university campus to analyze the current situation and suggesting noise control measures to be adopted in University campus and along MMA Jauhar Marg. The numbers of vehicles were counted during November 17-21, 2012 and noise levels were measured at various pre decided locations. The traffic load in horizon years 2013, 2017, 2022, 2027 and 2032 on the MMA Jauhar Marg Road is predicted on the basis of observed traffic data and expected annual growth rate as 8.0% for pre Metro and 3.5% for post Metro. The noise levels were measured using Larson Davis Model 831 Class 1 Sound Level Meter on both sides of road at foot paths along MMA Jauhar Marg and at various receptor locations inside the different buildings in the university campus. Model RLS-90 is used for prediction of noise levels. The prediction of metro noise is carried out using statistical calculations. The combined noise levels were compared with standard criteria for silent zone and found on higher side. Installation of environment noise barrier is suggested as one of the noise control measure to be adopted along MMA Jauhar Marg and along metro viaduct to save students and staff from exposure of higher noise levels.

    2016-01-01

    Summary Objectives The objective of this study was to evaluate the association between socioeconomic factors and asthma control in children, as defined by the Canadian Pediatric Asthma Consensus Guidelines. Patients and Methods Cross-sectional data from a completed study of 879 asthmatic children between the ages of 1 and 18 residing in the Greater Toronto Area were used. The database included data on demographics, health status, asthma control, and health-related quality of life. Stepwise forward modeling multiple regression was used to investigate the impact of socioeconomic status on asthma control, based on six control parameters from the 2003 Canadian Pediatric Asthma Consensus Guidelines. Results Only 11% of patients met the requirements for acceptable control, while 20% had intermediate control, and 69% had unacceptable asthma control. Children from families in lower income adequacy levels had poorer control. Conclusions Disparities in asthma control between children from families of different socio-economic strata persist, even with adjustment for utilization of primary care services and use of controller medications.

    Urban agriculture is becoming an important lucrative activity in Dar es Salaam City even though the city is subject to traffic and industrial pollution pressures. Poor planning has left only limited spaces, particularly road reserves, for cultivation and foraging animals. While there is increasing road traffic no study bas been conducted determine levels of trace metals in pasture grasses. This study, therefore, reports on the levels of cadmium, manganese, lead and zinc of cynodon grasses in road vicinity in the city. Results show that the trace metal levels (ppm ± SDE) in Cynodon grass species were: Cd (0.24 ± 0.06-2.58 ± 0.15), Mn (41.5 ± 13.6-345.0 ± 124.3), Pb (1.15 ± 0.64-25.53 ± 1.29) and Zn (25.97 ± 3.69-95.36 ± 19.61). The mean levels of lead and zinc varied exponentially with distance off the road up to 15 m distance. Lead and zinc levels correlated with average daily traffic in the roads while cadmium and manganese did not. This suggests that lead and zinc in grasses owe their sources from the passing motor vehicles in agreement with other reported studies. It is recommended that pasture grasses in road vicinities must not be used for foraging dairy cattle and goats for public health reasons.

    Air quality in the residential areas adjacent to the industrial regions is of great concern due to the association with human health risks. In this work, the concentrations of particulate matter (PM10) in the ambient air of UTHM campus was investigated tostudy the air qualityand their compliance to the Malaysian Ambient Air Quality Guidelines (AAQG). The PM10 samples were taken over 24 hours from the most significant area at UTHM including Stadium, KolejKediamanTunDr. Ismail (KKTDI) and MakmalBahan. The meteorological parameters; temperature, relative humidity, wind speed and wind direction as well as particulate matterwere estimated by using E-Sampler Particulate Matter (PM10) Collector. The highest concentrations of PM10 (55.56 µg/m3) was recorded at MakmalBahan during the working and weekend days. However, these concentrations are less than 150 pg/m3. It can be concluded that although UTHM is surrounded by the industrial area, the air quality in the campus still within the standards limits.

    Five aromatic hydrocarbons (benzene, toluene, and three isomeric xylenes) were monitored in indoor and outdoor air of 7 public buildings and 54 private homes, located in Barcelona City metropolitan area and in several rural areas of Catalonia. The sampling was carried out over four periods: spring-summer and winter of 2000, and summer and winter of 2001. Passive ORSA 5 Draiger samplers were used for benzene, toluene, and xylenes (BTX) adsorption. BTX were extracted with carbon disulphide and analysed using a gas chromatograph coupled to a FID detector. In Barcelona metropolitan area the outdoor average concentrations of BTX were 3.5, 34.2, and 31.3 μg/m3 in urban areas, and 1.4, 9.2, and 9.2 μg/m3 in rural areas, respectively. Average indoor air concentrations of BTX were respectively 4.3, 64.8, and 47.6 μg/m3 in urban areas and 5.8, 67.0, and 51.4 μg/m3 in rural areas, respectively. A direct connection between the house and garage was one of the most influential factors for indoor BTX concentrations in rural areas. In urban areas, diffuse traffic sources were the predominant BTX source, slightly influenced by tobacco smoke in indoor air.

  7. Socioeconomic assessment: issues, status, and plans

    International Nuclear Information System (INIS)

    Numerous public meetings and hearings have been held in Texas, Mississippi, Louisiana and Utah on the issue of siting a nuclear waste repository in salt. Citizens in these potential site areas have raised many questions about how this facility will affect their quality of life. Questions about population and economic changes have been of particular concern. In developing a socioeconomic program, these issues and others have been an integral part of Battelle's socioeconomic studies. The three elements of Battelle's socioeconomic program are comprised of three elements: impact assessment, impact mitigation and community development, and impact monitoring. In addition, our approach to assessing socioeconomic impacts for the environmental assessment (EA) required by the Nuclear Waste Policy Act of 1982 are described. Since the EA analysis will address many of the issues raised in the site areas, these concerns will be elaborated on. Finally, various techniques for managing socioeconomic impacts will be presented. 6 references, 1 figure

    Full Text Available Abstract Background The socioeconomic and sociodemographic situation are important components for the design and assessment of malaria control measures. In malaria endemic areas, however, valid classification of socioeconomic factors is difficult due to the lack of standardized tax and income data. The objective of this study was to quantify household socioeconomic levels using principal component analyses (PCA to a set of indicator variables and to use a classification scheme for the multivariate analysis of children Methods In total, 1,496 children presenting to the hospital were examined for malaria parasites and interviewed with a standardized questionnaire. The information of eleven indicators of the family's housing situation was reduced by PCA to a socioeconomic score, which was then classified into three socioeconomic status (poor, average and rich. Their influence on the malaria occurrence was analysed together with malaria risk co-factors, such as sex, parent's educational and ethnic background, number of children living in a household, applied malaria protection measures, place of residence and age of the child and the mother. Results The multivariate regression analysis demonstrated that the proportion of children with malaria decreased with increasing socioeconomic status as classified by PCA (p Conclusions The socioeconomic situation is significantly associated with malaria even in holoendemic rural areas where economic differences are not much pronounced. Valid classification of the socioeconomic level is crucial to be considered as confounder in intervention trials and in the planning of malaria control measures.

    2016-01-01

    Background: Health status is largely determined by socio-economic status. The general health of individuals at higher social hierarchy is better than people in lower levels. Likewise, people with higher socio-economic status have better oral health than lower socio-economic groups. There has not been much work regarding the influence of socio-economic status on the health conditions of children in developing countries, particularly in Iran. The aim of this study was to compare the oral and general health conditions of primary school children of three different socio-economic areas in the city of Shiraz, Iran. Methods: This cross-sectional study was conducted on 335, 8- to 11-year-old primary schoolchildren in Shiraz. The children were selected by a three-stage cluster sampling method from three socio-economically different areas. Tools and methods used by the United Kingdom’s Medical Research Council were used to obtain anthropometric variables as indicators of general health. The Decay, Missing, Filled Teeth (DMFT) Index for permanent teeth, dmft Index for primary teeth, the Modified Developmental Defects of Enamel (DDE) Index, the Gingival Index (GI) and the Debris Index-Simplified (DI-S) were used for oral health assessment.  Results: Height (P<0.001), weight (P<0.001), and BMI (P=0.001) significantly increased as the socio-economic status of area increased. GI score (P<0.001), DI-S score (P<0.001), number of permanent teeth with DDE (P=0.008), and number of DDE lesions in permanent teeth (P=0.008) significantly decreased as the socio-economic status of area increased. Discussion: Findings of this study generally confirmed that social gradients exist in both general and oral health status of the primary schoolchildren of Shiraz. The influence of socio-economic status on health condition means children have different life chances based on their socio-economic conditions. These findings emphasize the significance of interventions for tackling socio-economic

    The objective of this article is to estimate the own-price, cross-price and income elasticities of demand for SSB in Ecuador, as an indispensable step for predicting a reduction in the consumption of said beverages caused by the potential implementation of taxes in Ecuador. In addition, the own-price, cross-price and income elasticities of sugar-free substitutes like mineral water and diet soft drinks and juices are also estimated. The data from the 2011-2012 ENIGHUR, which contains detailed information on household consumption and socioeconomic variables, was used. The estimates are done using Deaton's Almost Ideal Demand System (AIDS) which accounts for differences in the quality of goods purchased. This demand system is estimated for different socio-economic groups, according to total household expenditure. The results reveal own-price elasticities for SSB between -1.17 and -1.33 depending on the socio-economic group, in line with the existing evidence for developed countries. Own-price elasticity for non-SSB is between -1 and -1.24. Income elasticities reveal that both SSB and non-SSB are normal goods with elasticities decreasing for higher socio-economic groups. These results show that the consumption of SSB is sensitive to price changes, meaning that the implementation of taxes on said beverages could be effective in reducing their consumption. The fact that non-SSB are also sensitive to price changes would indicate that subsidies could be implemented for the production of some of them. PMID:27028608

    Poor feeding practices among young children lead to malnutrition, and the poor are at a greater risk than the better off groups. Child-feeding practices in various socio-economic strata, especially in urban settings, have not yet been well studied in Indonesia. This study aims to explore the feeding practices of 12-23 months old children from different socio-economic status (SES) groups. A cross-sectional survey was conducted, which included low (n 207), medium-high (n 205), medium-low (n 208) and high SES households (n 194) in forty-three villages within thirty-three sub-districts of Bandung city. Two non-consecutive 24 h recall and eight core indicators of child-feeding practices were assessed through interviews. The results showed that children from the high SES group were more likely to be exclusively breast-fed and to continue breast-feeding up to 1 year of age, met minimum dietary diversity and minimum acceptable diet, and also consumed Fe-rich or Fe-fortified foods. In contrast, children from low SES consumed more energy-rich food (grain) but fewer foods from the other food groups. Consumption of major nutrients differed across the SES groups. Inadequate nutrition was higher among children from the lower SES groups. Fortified foods were consumed by a larger proportion of children from the high SES group and contributed considerably to their overall nutrient intake. This study shows that young children's feeding practices were not adequate, most notably among the low SES households. However, after adjusting with potential confounders, there was not enough evidence to conclude SES as a risk factor for feeding practice. PMID:26388172

    Institutional and socioeconomic aspects of water supply Within the project CC-WaterS the participating researchers of the Vienna University of Economics and B.A. have been responsible for the analysis of the socioeconomic aspects related to water supply and climate change, the assessment of future water demands in the City of Vienna, as well as an estimation of economic consequences of possible water shortages and possible scope for the introduction of new legal guidelines. The institutional and socioeconomic dimensions of drinking water and sanitation systems are being examined by utilisation of different prognostic scenarios in order to assess future costs of water provisioning and future demands of main water users, thus providing an information basis and recommendations for policy and decision makers in the water sector. These dimensions, for example, include EU legislation - especially the Water Framework Directive -, national legislations and strategies targeted at achieving sustainability in water usage, best practices and different forms of regulating water markets, and an analysis of the implications of demographic change. As a basis this task encompasses research of given institutional, social, and legal-political structures in the area of water supply. In this course we provide an analysis of the structural characteristics of water markets, the role of water prices, the increasing perception of water as an economic good as well as implications thereof, the public awareness in regard to climate change and water resources, as well as related legal aspects and involved actors from regional to international level; and show how water resources and the different systems of water provisioning are affected by (ideological) conflicts on various levels. Furthermore, and in order to provide a solid basis for management recommendations related to climate change and water supply, an analytical risk-assessment framework based on the concepts of new institutional

It is unclear if CRC screening varies geographically, if area-level poverty rate affects CRC screening, and if individual-level characteristics mediate the area-level effects on CRC screening. Methods Using 2006 Missouri Behavioral Risk Factor Surveillance System (BRFSS data, a multilevel study was conducted to examine geographic variation and the effect of area-level poverty rate on CRC screening use among persons age 50 or older. Individuals were nested within ZIP codes (ZIP5 areas, which in turn, were nested within aggregations of ZIP codes (ZIP3 areas. Six groups of individual-level covariates were considered as potential mediators. Results An estimated 51.8% of Missourians aged 50 or older adhered to CRC screening recommendations. Nearly 15% of the total variation in CRC screening lay between ZIP5 areas. Persons residing in ZIP5 areas with ≥ 10% of poverty rate had lower odds of CRC screening use than those residing in ZIP5 areas with Conclusion Large geographic variation of CRC screening exists in Missouri. Area-level poverty rate, independent of individual-level characteristics, is a significant predictor of CRC screening, but it only explains a small portion of the geographic heterogeneity of CRC screening. Individual-level factors we examined do not mediate the effect of the area-level poverty rate on CRC screening. Future studies should identify other area- and individual-level characteristics associated with CRC screening in Missouri.

To study the socio-economic status of households using iodized salt and thyrotropin hormone level in urban areas. Riskesdas data 2007 that include 280.000 households was used.Thyrotropin hormone data include 9.457 people aged above 1 years. Variables included classification of village, rapid test on salt, education and occupation of households’ head, household expenditure and level of thyrotropin hormone. Around 80 percentof households where households’ head graduated from college/university used salt containing sufficient iodine. Only 18 percent households with households’ headworks as government workers used salt containing sufficient iodine. Around 70 percent households in 5th quintile of household’s expenditure were using salt with sufficient iodine content. Around 70 percent households in urban areas were using salt withsufficient iodine content.Among children 1-4 years, percentage of low category of thyrotropin hormon level was 3.3 percentand among 60 years of age and above was 15.8 percent. The higher the educational levelthe higher the percentage of households used salt with sufficient iodine. Percentage of households using salt with sufficient iodine was higher in urban than in rural areas. The higher the quintiles of household expenditures the higher the percentage of households using salt with sufficient iodine.

    Full Text Available Planners and researchers have realized that larger regional framework of urban areas are significant in assessing various inequality aspects in a developing country like India. The framework consists of heterogeneity in spatial and demographic aspects and in quality of socio-economic development levels as well. Against this background, the present paper has proposed a methodological framework to assess socio-economic inequality within Bangalore Urban Agglomeration (BUA as governed by the composite set of Human Development Index (HDI based indicators. Assessments are based on local data of dwellers' preferences on the indicators. On the whole, this paper has tried to establish the significance of application of HDI based indicators in an assessment of socio-economic inequality within BUA. Consequently, the paper has arrived at the need for improvement of comprehensive HDI governed basic public services, amenities, and advanced facilities, across all trans-urban-area levels to ensure a holistic development within BUA.

    2011-03-01

    A physical activity and nutrition community intervention called the Oxford Hills Healthy Moms (OHHM) Project was developed using a multifaceted social marketing process, including review of state surveillance results, key informant interviews, and a survey and focus group discussions with low-socioeconomic-status (low-SES) mothers. This formative work was used to make key decisions on the selection of the intervention region, segmentation of the audience, and design of intervention strategies addressing multiple levels of the socioecological model. The OHHM Project aims to increase fruit and vegetable consumption and physical activity levels among low-SES mothers in the Oxford Hills region of Maine. The OHHM Project includes five components: (a) physical activity buddy program, (b) cooking club with education, (c) fruit and vegetable discount buying club with education, (d) increased access to produce vendors, and (e) increased access to places for physical activity.

  13. Socioeconomic profile of Clark County, Nevada: Community services inventory

    International Nuclear Information System (INIS)

    The Nevada Nuclear Waste Storage Investigations Project is preparing socioeconomic profiles of Clark County, Nevada, and communities in Clark County that could be affected by siting, construction, operation, and decommissioning of a high-level nuclear waste repository at Yucca Mountain, located in Nye County. These profiles serve as a data base for evaluating local community service impacts; store existing socioeconomic data in a uniform, readily accessible format; identify the need for additional data; and assist in developing a plan for monitoring and mitigating any significant adverse impacts that may be associated with site characterization and potential repository development. This element of the socioeconomic profiles contains an inventory of community services provided by local, county, and state agencies and volunteer organizations to residents of Las Vegas, North Las Vegas, Henderson, Boulder City, Indian Springs, and unincorporated areas of the county. Services inventoried include housing, growth management, general government, education, police protection, transportation networks, public clinics, private health personnel, parks and recreation, social services, libraries, ambulances, electric power, natural gas, water, sewers and wastewater treatment, solid waste, and fire protection. The report includes a summary overview of service providers in Clark County, discussions of the services provided to residents of communities in Clark County that may be affected by Project activities, and a description of service providers whose service areas are not limited to the incorporated areas of Clark County. Data presented in this profile were collected through March of 1985. Data collection efforts are ongoing and this profile will be updated periodically

    2016-01-01

    Thousand and twelve dementia-free elderly (60–98 years old) enrolled in the In Chianti Study (Italy) were evaluated at baseline (1998–2000) and at 3-year follow-up (2001–2003) with the aim of analyzing the association of lifetime socioeconomic status (SES) with prevalent and incident cognitive impairment no-dementia (CIND). SES was defined from information on formal education, longest held occupation, and financial conditions through life. CIND was defined as age-adjusted Mini-Mental State Examination score one standard deviation below the baseline mean score of participants without dementia. Logistic regression and Cox proportional-hazards models were used to estimate the association of SES with CIND. Demographics, occupation characteristics (i.e., job stress and physical demand), cardiovascular diseases, diabetes, apolipoprotein E (APOE) genotype, smoking, alcohol consumption, depressive symptoms, and C-reactive protein were considered potential confounders. Prevalence of CIND was 17.7%. In the fully adjusted model, low education (OR = 2.1; 95% confidence intervals, CI = 1.4 to 3.2) was associated with prevalent CIND. Incidence rate of CIND was 66.0 per 1000 person-years. Low education (HR = 1.7; 95% CI = 1.04 to 2.6) and manual occupation (HR = 1.9; 95% CI =1.0 to 3.6) were associated with incident CIND. Among covariates, high job-related physical demand was associated with both prevalent and incident CIND (OR = 1.6; 95% CI = 1.1 to 2.4 and HR = 1.5; 95% CI = 1.0 to 2.3). After stratification for education, manual occupation was still associated with CIND among participants with high education (HR = 2.2; 95% CI = 1.2 to 4.3 versus HR = 1.4; 95% CI = 0.2 to 10.4 among those with low education). Proxy markers of lifetime SES (low education, manual occupation and high physical demand) are cross-sectional correlates of CIND and predict incident CIND over a three-year follow-up. PMID:21297261

    2016-03-01

    The solid waste generation rate was expected to vary in different socioeconomic groups due to many environmental and social factors. This paper reports the assessment of solid waste generation based on different socioeconomic parameters like education, occupation, income of the family, number of family members etc. A questionnaire survey was conducted in the study area to identify the different socioeconomic groups that may affect the solid waste generation rate and composition. The average waste generated in the municipality is 0.41 kg/capita/day in which the maximum waste was found to be generated by lower middle socioeconomic group (LMSEG) with average waste generation of 0.46 kg/capita/day. Waste characterization indicated that there was no much difference in the composition of wastes among different socioeconomic groups except ash residue and plastic. Ash residue is found to increase as we move lower down the socioeconomic groups with maximum (31%) in lower socioeconomic group (LSEG). The study area is a coal based city hence application of coal and wood as fuel for cooking in the lower socioeconomic group is the reason for high amount of ash content. Plastic waste is maximum (15%) in higher socioeconomic group (HSEG) and minimum (1%) in LSEG. Food waste is a major component of generated waste in almost every socioeconomic group with maximum (38%) in case of HSEG and minimum (28%) in LSEG. This study provides new insights on the role of various socioeconomic parameters on generation of household wastes. PMID:26831564

  17. Neutron activation analysis of neonate and maternal hair sampled in areas with different levels of pollution

    International Nuclear Information System (INIS)

    Instrumental neutron activation analysis was performed on human head hair of newborns and mothers sampled in two areas with different levels of environmental exposure. The group of neonates from the exposed area (polluted by thermal power plants burning brown coal and by chemical industry) exhibited higher levels of several trace elements in hair, e.g. Se, Zn, Hg and Sb in comparison with the control group. Moreover, the mean concentrations of Se, Hg, Zn and Br in neonate hair were found to be higher than in mothers' hair. Although the study revealed statistically significant differences in the composition of neonate hair samples in areas with different levels of environmental exposure, the differences are relatively small. Only a thorough long-term study both with environmental and medical observations can prove a direct connection of the elevated levels of some trace elements in neonate hair with the higher incidence of mental diseaes of children living in the exposed area.

    This article investigates the variations of contamination levels of heavy metals such as copper, lead, chromium, cadmium, zinc, arsenic, and mercury over time in surface sediments of the Changjiang River Estuary (CRE), Yellow River Estuary (YRE), Pearl River Estuary (PRE), and their adjacent coastal areas in China. The contamination factor (CF), pollution load index (PLI), and geoaccumulation index (I geo) are used to evaluate the quality of the surface sediments in the study areas. The results showed that the CRE, YRE, and their adjacent coastal areas were at a low risk of contamination in terms of heavy metals, while the PRE and its adjacent coastal area were at a moderate level. By comparison, the concentrations of heavy metals in the surface sediments of the YRE and its adjacent coastal area were relatively lower than those in the CRE, PRE, and their adjacent coastal areas.

    This study examined the association between unemployment and life expectancy in the United States during 1990-2010. Census-based unemployment rates were linked to US county-level mortality data. Life expectancies were calculated by age, sex, race, and unemployment level during 1990-2010. Differences in life expectancy were decomposed by age and cause of death. Life expectancy was consistently lower in areas with higher unemployment rates. In 2006-2010, those in areas with high unemployment rates (≥9%) had a life expectancy of 76.9 years, compared with 80.7 years for those in areas with low unemployment rates (Heart disease, cancer, homicide, unintentional injuries, diabetes, HIV/AIDS, and liver cirrhosis contributed most to the lower life expectancy in high unemployment areas. High unemployment areas recorded larger gains in life expectancy than low unemployment areas, contributing to the narrowing gap during 1990-2010. PMID:27073716

    Objective:To explore the relationship between socioeconomic status from one side and physi-cal growth and nutritional status from the other side, in infants versus adolescents in Egyptians. Methods: Three samples were investigated:a) A sample of 605 infants aged 6 months+1 week (287 girls and 318 boys). B) A sample of 992 infants of age 4-24 months (465 girls and 527 boys). C) A sample of 1864 chil-dren and adolescents aged 6-14 years of (744 girls and 1120 boys). All samples are from Big Cairo area of both urban and rural localities and of various socioeconomic strata. Body weight and length/height had been measured and body mass index (BMI) had been calculated for every subject. Assessment of the impact of pa-rental education level, locality and number of sibs, on growth and nutrition as indicated by BMI was attemp-ted. Results: a) Breastfed infants (6 months +1 week) grow bigger in low socioeconomic strata and in rural areas than artificially fed infants. The practice of breast feeding was more common and lasted longer in low so-cioeconomic stratum than in middle and high one. B) A significant positive association between body mass in-dex of infants (4-24 months) and the socioeconomic status (particularly level of father education reflecting family income) was proved. C) The socioeconomic factors had insignificant influence on BMI of school chil-dren aged 6~9 years, but it showed significant influence in the period 10~14 years. After the age of 9 years, children started the pubertal stage earlier and had higher BMI in the high socioeconomic strata as com-pared to those of low socioeconomic strata. D) In the low socioeconomic status, breast feeding compensates the deleterious influences of the environment on growth and physique of infants. Conclusion: children of educated parents have significantly low number of siblings'size in comparison to those of uneducated parents. Also chil-dren of educated parents are significantly more in number in urban areas than

    Objectives To develop and optimise a primary care-based complex intervention (CARE Plus) to enhance the quality of life of patients with multimorbidity in the deprived areas. Methods Six co-design discussion groups involving 32 participants were held separately with multimorbid patients from the deprived areas, voluntary organisations, general practitioners and practice nurses working in the deprived areas. This was followed by piloting in two practices and further optimisation based on interviews with 11 general practitioners, 2 practice nurses and 6 participating multimorbid patients. Results Participants endorsed the need for longer consultations, relational continuity and a holistic approach. All felt that training and support of the health care staff was important. Most participants welcomed the idea of additional self-management support, though some practitioners were dubious about whether patients would use it. The pilot study led to changes including a revised care plan, the inclusion of mindfulness-based stress reduction techniques in the support of practitioners and patients, and the stream-lining of the written self-management support material for patients. Discussion We have co-designed and optimised an augmented primary care intervention involving a whole-system approach to enhance quality of life in multimorbid patients living in the deprived areas. CARE Plus will next be tested in a phase 2 cluster randomised controlled trial. PMID:27068113

  7. A survey for elevated levels of uranium north of the 300 Area on the Hanford Site

    International Nuclear Information System (INIS)

    A comprehensive survey of soil uranium (U) concentrations in a study area due north of the 300 Area on the Hanford site has been conducted by Pacific Northwest Laboratory (PNL). The objective of the study was to determine the spatial distribution of uranium in the study area and to ascertain if background levels of uranium have been increased by Hanford operations. Based on the spatial distribution of 238U, the highest concentrations of uranium are located in the southern portion of the study area adjacent to the 300 Area complex and in the most eastern zone of the study site bordering the Columbia River. Uranium-236, an isotopic marker of fuel processing activities in the 300 Area, was detected in all eight samples selected from the study. A significant and positive regression was demonstrated between the ratios of 236U/238U in these eight samples and proximity to the 300 Area. 9 refs., 18 figs., 9 tabs

  8. Area evolution of a few-cycle pulse laser in a two-level-atom medium

    International Nuclear Information System (INIS)

    By solving the Maxwell-Bloch equations, we study the area evolution of a few-cycle pulse laser propagating in a resonant two-level-atom medium. We find that in short propagation distance, the pulse envelope, obtained within the slowly varying envelope approximation and the rotating-wave approximation, agrees nicely with the carrier field. In this case, the area theorem can still predict the profile of the area evolution of a few-cycle optical pulse. However, contrary to the long-pulse case, the variation of the few-cycle pulse area is caused by the pulse splitting but not by the pulse broadening or the pulse compression. Furthermore, the negative area occurs when the pulse area decreases. As a result, a pulse with area less than π is not absorbed rapidly according to the usual Beer's law of absorption but evolves to nonvanishing zero π pulse

  9. Brazilian low and intermediate level radioactive waste disposal and environmental conservation areas

    International Nuclear Information System (INIS)

    Low and intermediate level radioactive waste should be disposed off in proper disposal facilities. These facilities must include unoccupied areas as protection barriers, also called buffer zone. Besides that, Brazilian environmental laws require that certain enterprises must preserve part of their area for environmental conservation. The future Brazilian low and intermediate level waste repository (RBMN) might be classified as such enterprise.

The possibility of creating a plant repository in the buffer zone is also discussed. (author)

  10. Analysis on the feasibility of high level radioactive waste disposal repository establishment in Kuluketage area

    International Nuclear Information System (INIS)

    This paper summarizes the research results of Kuluketage area natural environment, granite rock mass, regional crust stability and groundwater circle in Xinjiang. It shows that this region has some advantages for the deep geological disposal of high-level radioactive waste, for its arid climate, little precipitation and human activity; wide distribution and large area of granite; stability of geological structure and feebleness of earthquake movement; and because groundwater drainage is far away human inhabitation place. Establishing high-level radioactive waste disposal repository in Kuluketage area is little influence to human and economy and environment. (authors)

    Full Text Available This study examined the association between unemployment and life expectancy in the United States during 1990–2010. Census-based unemployment rates were linked to US county-level mortality data. Life expectancies were calculated by age, sex, race, and unemployment level during 1990–2010. Differences in life expectancy were decomposed by age and cause of death. Life expectancy was consistently lower in areas with higher unemployment rates. In 2006–2010, those in areas with high unemployment rates (≥9% had a life expectancy of 76.9 years, compared with 80.7 years for those in areas with low unemployment rates (<3%. The association between unemployment and life expectancy was stronger for men than for women. Life expectancy ranged from 69.9 years among black men in high unemployment areas to 90.0 years among Asian/Pacific Islander women in low unemployment areas. Disparities persisted over time. In 1990–1992, life expectancy was 4.7 years shorter in high unemployment than in low unemployment areas. In 2006–2010, the life expectancy difference between the lowest and highest unemployment areas decreased to 3.8 years. Heart disease, cancer, homicide, unintentional injuries, diabetes, HIV/AIDS, and liver cirrhosis contributed most to the lower life expectancy in high unemployment areas. High unemployment areas recorded larger gains in life expectancy than low unemployment areas, contributing to the narrowing gap during 1990–2010.

    The climate of semi-arid Mediterranean areas is characterized by highly variable rainfall and seasonal droughts, which favor highly specialized flora, high biodiversity, and the emergence of a large number of endemic species. Such highly specialized complex ecosystems are expected to be more difficult to return to a previous state following perturbation than are more mild ecosystems and lead to dramatic transitions in vegetation. An understanding of the circumstances under which irreversible ...

  13. Climate change. Socio-economic impacts and violent conflict

    International Nuclear Information System (INIS)

    The results of a literature study on the socio-economic impacts of climate change and the possibilities of violent conflicts enhanced by the greenhouse effect are presented. The socio-economic impacts are classified according to the economic sectors agriculture, forestry, fishery, energy, water, construction, transport, tourism and recreation and discussed in Chapter 2. The impacts on property, ecosystems and human well being are outlined in chapter 3. Chapter 4 deals with climate change and environmental security, and discusses the most important concepts of security and their relation to climate change. Chapter 5 deals with already existing and potential conflicts, that may be enhanced by the greenhouse effect as a result of resource scarcity, particularly related to availability of food and water. On the basis of the literature study and an analysis of research gaps propositions are made on new areas of research to be undertaken. The study emphasizes the need to further study the impact on agriculture in semi-arid zones, the impact on water availability in sensitive regions, a further analysis of the consequences of sea level rise particularly in sensitive areas and with regard to forced migration. Also further studies are required into the socio-economic impacts of changes in human health and mortality due to climate change, in relation to diseases. Special attention should be paid to migration because of environmental degradation and flooding. Extreme weather events have already been studied, but there still is a need for further insights into how extreme weather events will affect society, taking into account adaptive behaviour. Finally, in the area of socio-economic impacts, the implications of changes in ecosystems and biodiversity require further attention as these effects may be large but, at the same time, difficult to assess in economic terms. 175 refs

    Climate change has significant repercussions on the natural environment, triggering obvious changes in the natural processes that have a severe socio-economic impact on the coastal zone; where a great number of human activities are concentrated. So far, the estimation of coastal vulnerability was based primarily on the natural processes and less on socio-economic variables, which would assist in the identification of vulnerable areas. The present investigation proposes a methodology to examine the vulnerability of a highly touristic area in the Island of Crete to an expected sea level rise of up to ~40 cm by the year 2100, according to the A1B scenario of IPCC 2007. The methodology includes the combination of socio-economic indicators into a GIS-based coastal vulnerability index for wave-induced erosion. This approach includes three sub-indices that contribute equally to the overall index. The sub-indices refer to coastal forcing, socio-economic and coastal characteristics. All variables are ranked on a 1-5 scale with 5 indicating higher vulnerability. The socio-economic sub-index includes, as indicators, the population of the study area, cultural heritage sites, transport networks, land use and protection measures. The coastal forcing sub-index includes the frequency of extreme events, while the Coastal Vulnerability Index includes the geological variables (coastal geomorphology, historical coastline changes, and regional coastal slope) and the variables representing the marine processes (relative sea level rise, mean significant wave height, and tidal range). The main difficulty for the estimation of the index lies in assessing and ranking the socio-economic indicators. The whole approach was tested and validated through field and desktop studies, using as a case study the Elouda bay, Crete Isl., an area of high cultural and economic value, which combines monuments from ancient and medieval times, with a very high touristic development since the 1970s.

    All the Natural Protected Areas (NPA) within the Central Mexico City Belt comprising five metropolitan areas including MCMA are under strong impact from air pollution. Ozone, nitrogen oxides and sulfur dioxide exceed critical levels for several types of vegetation. In this work we show the critical level maps for ozone, nitrogen oxides and sulfur dioxide for Sierra of Chichinautzin, the mountain that acts as the physical barrier to air pollution dispersion south of Mexico City Metropolitan Area, what makes of it a receptor area to MCMA pollution. Maps were made combining model outputs from WRF-Chem and passive samplers. We also describe a proposal to extend the observation network to all natural protected areas within the Central Mexico City Belt.

    We report an analytic solution for a three-level atom driven by arbitrary time-dependent electromagnetic pulses. In particular, we consider far-detuned driving pulses and show an excellent match between our analytic result and the numerical simulations. We use our solution to derive a pulse area theorem for three-level V and Λ systems without making the rotating wave approximation. Formulated as an energy conservation law, this pulse area theorem can be used to understand pulse propagation through three-level media.

    Variational descriptions for various multiphase level set formulations involving curvature flow are discussed. A representation of $n$ phases using $n−1$ level set functions is introduced having the advantage that constraints preventing overlaps or vacuum are not needed. The representation is then used in conjunction with our variational formulation to deduce a novel level set based algorithm for multiphase flow. In addition, a similar variational formulation is applied to area preserving cur...

  18. Epidemiological studies in the high and normal level radiation areas of Kerala

    International Nuclear Information System (INIS)

    High and normal level natural radiation areas of Kerala give unique opportunities to estimate the risk, if any, of chronic low dose exposure by direct epidemiological studies on human beings. Studies in the area are being carried out by Low Level Radiation Research Laboratory of Bhabha Atomic Research Centre in collaboration with Departments of Health and Family Welfare/Social Welfare of the Government of Kerala and local post graduate colleges. To assess the role of chronic low dose exposure in the induction/transmission of chromosomal alterations across generations, hospital based cytogenetic studies on newborns was carried out to estimate and compare the frequency of chromosomal aberrations and karyotypes anomalies in the high (areas with radiation dose of more than 1.50 mGy/year) and normal (areas with radiation dose of 1.50 mR/year or less) level radiation areas. A total of 1,267,788 metaphases from 27,295 (9,64,390 cells from 17,298 newborns of high and 3,03,398 cells from 9,997 newborns of normal level radiation areas) newborns was screened

    Full Text Available The study for coastal vulnerability to sea level rise was carried out in Surabaya and its surrounding area, it has focused on calculations of the physical vulnerability index were used coastal vulnerability index (CVI methods. It was standardized by the multi criteria analysis (MCA approach according to the study area.The score of each physical variable derived from remote sensing satellite data and the results of studies that have been done, such as modeling results and thematic maps, and then integrated into geographic information systems (GIS. Result of this study showsthat the coastal areas of Gresik, Surabaya, and Sidoarjo in the very low to very high vulnerability level. Physically, the low land areas with open and slightly open coastal have a high vulnerability category. The high level vulnerability was found located in the northern of Madura Strait (Gresik Regency that overlooks to the Java Sea is about 28.81% from the entire of study areas. Meanwhile, the moderate, low and very low levels of vulnerability were located on Surabaya and Sidoarjo Regency that have more protected coastal area,relatively. According to the physical condition, the coastal elevation is the most variable that contributes to the high of vulnerability index in the coastal of Surabaya City and Sidoarjo Regency.

  20. Mortality and cancer incidence in Misasa, Japan, a spa area with elevated radon levels

    International Nuclear Information System (INIS)

    A historical cohort study was conducted in Misasa town, Tottori prefecture, Japan, where radon spas have been operating for a long time. Misasa town was divided into an elevated radon level area and a control area, with mean indoor radon levels of about 60 and 20 Bq/m3, respectively. In total, 3,083 subjects in the elevated radon level area and 1,248 in the control area, all aged 40 or older on January 1, 1976, were followed up until December 31, 1993, for a mean period of 14 years. The mortality rates from all causes exhibited no difference between the elevated radon level area and the control area for both sexes. No difference was observed in the incidence of all-site cancers (age, period-adjusted rate ratios by Poisson regression, RR=1.06, 95% confidence interval (CI) 0.79-1.42 for males, RR=0.90, 95%CI 0.65-1.24 for females), while stomach cancer incidence seemed to decrease for both sexes (RR=0.70, 95%CI 0.44-1.11 for male, RR=0.58, 95%CI 0.34-1.00 for female) and lung cancer incidence for males only seemed to increase (RR=1.65, 95%CI 0.83-3.30 for male, RR=1.07, 95%CI 0.28-4.14 for female) in the elevated radon level area. Caution is needed in the interpretation of these findings, however, since the individual exposure level was not measured and major confounding factors, such as smoking and diet, could not be controlled in this study.

  1. Cytogenetic studies on newborns from high level natural background radiation areas of Kerala coast, South India

    International Nuclear Information System (INIS)

    The human population residing in the monazite bearing high level natural background radiation (HLNBR) areas of Kerala, along the South-West coast of India provides unique opportunities of assessing directly in man, the health effects of chronic low-level radiation exposure. The per capita dose received by this population is nearly four times the normal background radiation level. While this is the average dose, the radiation levels prevailing in these HLNBR areas are in the range of 1 to over 35 mGy per year. Chromosomal aberration studies in the lymphocytes of newborns and adults from these areas have been in progress for two decades. So far, 4156 newborn babies from HLNBR and 7321 from normal background radiation (NBR) areas have been screened for the incidence of chromosomal aberrations (dicentrics and rings). The mean frequency of dicentrics and rings did not show any significant difference between the newborns in the control and the HLNBRA population. Assessment of the frequency of micronuclei in cytochalasin-B blocked binucleated lymphocytes of 49 newborns from control areas and 131 newborns from radioactive areas also showed similar values. While an age-dependent increase in chromosome aberration frequency was observed in the adult samples from control and the study areas, the regression analysis of the data indicated a marginally higher slope for the samples from HLNBRA. Karyotype anomalies recorded so far among the newborns have not revealed any significant difference in the incidence of numerical (including Down syndrome) and structural alterations between the control and the exposed populations. A noteworthy observation, herein reported for the first time from any HLNBR area is that there is no discernible increase in the incidence of micronuclei and chromosomal aberrations in the peripheral lymphocytes of newborn babies hailing from HLNBR areas, where their ancestral generations have lived for several hundreds of years.

    2013-05-01

    Full Text Available In addition to the mounting empirical data on direct implications of climate change for natural and human systems, evidence is increasing for indirect climate change phenomena such as sea-level rise. Rising sea levels and associated marine intrusion into terrestria.htm"l environments are predicted to be among the most serious eventual consequences of climate change. The many complex and interacting factors affecting sea levels create considerable uncertainty in sea-level rise projections: conservative estimates are on the order of 0.5-1.0 m globally, while other estimates are much higher, approaching 6m. Marine intrusion associated with 1-6 m sea-level rise will impact species and habitats in coastal ecosystems severely. Examining areas most vulnerable to such impacts may allow design of appropriate adaptation and mitigation strategies. We present an overview of potential effects of 1m and 6m sea level rise for coastal conservation areas in the Indian Subcontinent. In particular, we examine the projected magnitude of areal losses in relevant biogeographic zones, ecoregions, protected areas (PAs and important bird areas (IBAs. In addition, we provide a more detailed and quantitative analysis of likely effects of marine intrusion on 22 coastal PAs and IBAs that provide critical habitat for birds in the form of breeding areas, migratory stopover sites and overwintering habitats. Several coastal PAs and IBAs are predicted to experience higher than 50% areal losses to marine intrusion. We explore consequences of such inundation levels for species and habitats in these areas.

  3. Theory and Method for Identifying Well Water Level Anomalies in a Groundwater Overdraft Area

    The overexploitation of underground water leads to the continuous drawdown of groundwater levels, change of water quality and dry-up in dynamic water level observation wells. Due to land subsidence, the well pipes uplift and the observation piping systems are damaged. These environmental geology problems can present serious difficulties for the identification of earthquake anomalies by groundwater level observation. Basied on hydrogeological theories and methods, the paper analyzes the relations of the water balance state of aquifers with stressstrain conditions and the water level regime, and then discusses preliminarily the theory and method for identifying well water level anomalies in a groundwater overdraft area. The result shows that we can accurately judge the nature of the anomaly according to the diffusion character of the drawdown funnel in the well area in combination with the aforementioned theory and method and multi-year variation patterns obtained from existing data. The results of the research are helpful for distinguishing the influence of single centralized water pumping from the long-term overdraft of water on the water level, correctly recognizing water level anomalies in the groundwater overdraft area and increasing the level of earthquake analysis and prediction.

  4. Estimating Radiological Doses to Predators Foraging in a Low-Level Radioactive Waste Management Area

    International Nuclear Information System (INIS)

    Since 1957, Los Alamos National Laboratory has operated Area G as its low-level, solid radioactive waste management and disposal area. Although the waste management area is developed, plants, small mammals, and avian and mammalian predators still occupy the less disturbed and revegetated portions of the land. For almost a decade, we have monitored the concentrations of selected radionuclides in soils, plants, and small mammals at Area G. The radionuclides tritium, plutonium-238, and plutonium-239 are regularly found at levels above regional background in all three media. Based on radionuclide concentrations in mice collected from 1994 to 1999, we calculated doses to higher trophic levels (owl, hawk, kestrel, and coyote) that forage on the waste management area. These predators play important functions in the regional ecosystems and are an important part of local Native American traditional tales that identify the uniqueness of their culture. The estimated doses are compared to Department of Energy's interim limit of 0.1 rad/day for the protection of terrestrial wildlife. We used exposure parameters that were derived from the literature for each receptor, including Environmental Protection Agency's exposure factors handbook. Estimated doses to predators ranged from 9E-06 to 2E-04 rad/day, assuming that they forage entirely on the waste management area. These doses are greater than those calculated for predators foraging exclusively in reference areas, but are still well below the interim dose limit. We believe that these calculated doses represent upper-bound estimates of exposure for local predators because the larger predators forage over areas that are much greater than the 63-acre waste management area. Based on these results, we concluded that predators foraging on this area do not face a hazard from radiological exposure under current site conditions

    Full Text Available Noise pollution associated with urbanisation is an emerging environmental problem in many developing countries including Ghana. In comparison with other pollutants, the control of environmental noise has been hampered by insufficient knowledge of its effects on humans and of dose–response relationships, as well as by a lack of sufficient data. The study set to quantify noise and obtain the perceptions of residents in selected neighbourhoods in the main commercial area of Cape Coast, Ghana. The focus was on five selected areas: commercial centres, road junctions/busy roads, passengers loading stations, high-density residential areas, and low-density residential areas. The range of noise pollution levels, LNP, at high-density residential areas is 58-68 dB (A, while that of low-density residential areas is 53-72 dB (A. The range of traffic noise index TNI at high-density residential areas is 34-107 dB (A, and that of low density residential areas is 27-65 dB (A. There is a wide disparity in the noise level exposure by the residents in high-density residential areas and that of low-density residential areas. At 90% confidence level, the Mean Square Ratio (MSR calculated for LNP is 65.02, while the tabulated value is 2.36. Similarly, at the same confidence level, the MSR calculated for TNI is 6.23 and the tabulated value remains as 2.36. Since, in the two cases, the calculated MSR is greater than the tabulated value, there is a significant difference (p<0.05 in the noise pollution level and TNI in the locations surveyed based on the data analyzed at 90% confidence level. About 82.1% of the respondents complained that the noise from the audio music shops and traffic is a nuisance. Noise levels at all the 10 measurement points exceeded the Ghana EPA recommended upper limit by values of 1-15 dB (A. This makes it imperative for the regulatory authority to enforce compliance on noise.

    There is an urgent need to identify the human influence on landscape as disturbance regimes was realized for prioritization of the protected areas. The present study has attempted to describe the landscape level assessment of fragmentation and disturbance index in protected areas of Rajasthan using remote sensing and GIS techniques. Geospatial analysis of disturbance regimes indicates 61.75% of the total Pas are under moderate disturbance index followed by 28.64% and 9.61% under low and high, respectively. Among the 28 protected areas – National Chambal WLS, Jaisamand WLS, Kumbhalgarh WLS, Sawai Man Singh WLS, Kailadevi WLS and Bandh BarathaWLS are representing high level of disturbance. The present study has emphasized the moderate to low disturbance regimes in protected areas, which infer low biotic pressure and conservation effectiveness of PA network in Rajasthan. The spatial information generated on PAs is of valuable use for forest management and developing conservation strategies.

  7. The Land Subsidence and Relative Sea Level Rise in Chinese Delta Areas

    2004-01-01

    Based on some experts' research effort, the problems of land subsidence and relative sea level rise in three Chinese delta areas(Huanghe, Changjiang and Zhujiang Delta) are analyzed and discussed in this paper. The authors' opinion is that the land subsidence is mainly induced by human activity and has made the greater contributions to the relative sea level rise and become one of the geological hazards in these areas. In Tianjin and Shanghai areas where had ever existed serious land subsidence problem, due to the positive and effective control methods, the ratio of man-induced land subsidence to relative sea level rise decreased from 80% - 90% in 1960s - 1970s to less than 60% at present. But it is estimated that in the next tens of years this ratio will still be considerable. So human being must keep its eyes on this phenomenon and take more positive countermeasures to control the land subsidenee.

    Full Text Available The article proves that managerial impact in the form of socio-economic projecting in the best way suits the task of integrated solutions to the problems of socio-economic development of a large city in the situation where it is supported by implementing differentiation of urban areas by the preparedness of city people to innovation in the social sphere, carried out by municipal administration. For social projecting in terms of a large city, distances within the level of well-being of social groups should be linked to the division of city on a territorial basis (into urban areas. It is displayed that socio-economic development of a large city can be achieved with a combination of programtarget approach to developing a strategy for such development together with the principles and technologies for socio-economic projecting. Optimization of administrative activity, based on the projecting socio-economic development of city, leads to a gradual increase in the volume and quality of social participation of city people in the implementation of city-wide strategic development programs.

    In this paper we present new relative sea-level data from southern Greenland, a key area for understanding the Greenland Ice Sheet (GIS) response to climate change. Within fourteen lakes and marine lagoons from the inner part of Bredefjord (Nordre Sermilik) in southern Greenland, isolations revealed by stratigraphic and palaeoecological analyses are dated and relative sea levels reconstructed. Due to coastal emergence caused by the GIS retreat within the area, the relative sea-level fell rapidly in the early Holocene between at least c. 9600 and c. 7300 cal. yrs BP attaining a rate of 2 cm per year between 9600 and 8000 cal. yrs BP. Spatial variability in relative sea-level changes is show for southern Greenland from a comparison with the Nanortalik and the Qaqortoq areas. The regression occurred about 2000 years later in the inner Bredefjord area, compared to the Nanortalik area, and about 1000 years later compared to the Qaqortoq area. This is a consequence of earlier deglaciation in areas located at the outer coast. Between c. 8000 cal. yrs BP and the present day, relative sea level was lower than today. The lowest relative sea level in the Inner Bredefjord area of between -5.4 and -15 m a.h.a.t. (above highest astronomical tide) was reached between 7000 and 1000 cal. yrs BP. The neoglacial readvance together with the collapse of the Laurentide peripheral bulge is probably responsible for the transgression in the Inner Bredefjord area, as has been indicated from the nearby sites Qaqortoq and Nanortalik. Our relative sea-level reconstructions showing spatial variability within southern Greenland have implications for Glacial Isostatic Adjustment (GIA) modelling and the understanding of the GIS ice sheet dynamics. The early Holocene regression is consistent with the recession of the southern sector of the GIS from the shelf edge at c. 22 000 cal. yrs BP, reaching inland of the present day outer coast by c. 12 000 cal. yrs BP, and its present margin by c. 10 500

    We examined the link between household chaos (i.e., noise, clutter, disarray, lack of routines) and maternal executive function (i.e., effortful regulation of attention and memory), and whether it varied as a function of socioeconomic risk (i.e., single parenthood, lower mother and father educational attainment, housing situation, and father unemployment). We hypothesized that: 1) higher levels of household chaos would be linked with poorer maternal executive function, even when controlling for other measures of cognitive functioning (e.g., verbal ability), and 2) this link would be strongest in the most socioeconomically distressed or lowest-socioeconomic status households. The diverse sample included 153 mothers from urban and rural areas who completed a questionnaire and a battery of cognitive executive function tasks and a verbal ability task in the laboratory. Results were mixed for Hypothesis 1, and consistent with Hypothesis 2. Two-thirds of the variance overlapped between household chaos and maternal executive function, but only in families with high levels of socioeconomic risk. This pattern was not found for chaos and maternal verbal ability, suggesting that the potentially deleterious effects of household chaos may be specific to maternal executive function. The findings implicate household chaos as a powerful statistical predictor of maternal executive function in socioeconomically distressed contexts. PMID:22563703

    For many years, practitioners have heard that middle level teachers are teachers of reading. As the standards movement gains strength, it is even more crucial that teachers explicitly teach key vocabulary that makes their students "insiders" when it comes to understanding the content areas. This article reminds the reader of the principles for…

    Heavy metals presented in toxic amounts can become injurious to human health. In areas where there is a high level of human activities on soils (such as agriculture and grazing) studies are therefore required from time to time to monitor levels of such metals in the soils in order to identify the point in time when toxicity problems become real. The 英文摘要: of this paper is to determine the concentrations of some trace metals (Cu, Mn, Fe, and Zn) in soils under cultivation and grazing practices in Shika, a rural area of Kaduna state of Nigeria. Method In this study, soil samples collected from three different categories of locations (cultivated, grazed, and uncultivated/non- grazed serving as a control) across Shika area, Nigeria, were analysed for some trace metal levels (Cu, Mn, Fe, and Zn) using atomic absorption spectrophotometry. For each category, multiple sites were chosen to accommodate all possible intra-category variations, especially in terms of land use and management history and topographic characteristics. Topsoil (0-15 cm) and subsoil (20-30 cm) samples were collected from every site and analysed for the above metals. Averaged values of the metals for the three categories revealed that Zn is the most abundant metal, followed by Fe, then Mn and Cu the least. Results The results obtained indicate that the cultivation practices, and to a lesser extent grazing, in the area result in higher levels of all the metals than in the control, suggesting that crop immobilization of the metals from soils of the area is low, and that their systematic accumulation is taking place in cultivated soils of the area. Prospects of having elevated soil levels of the metals due to cultivation practices in the area therefore seem quite high. Conclusion On the basis of the results obtained, it was concluded that grazing and cultivation practices have in general caused some significant elevations in the bioavailable (i.e the plant available forms) levels of Zn, Fe, Mn

    Full Text Available The last two decades have seen many efficient algorithms and architectures for the design of low -complexity bit-parallel Multiple Constant Multiplications (MCM operation, which dominates the complexity of Digital Signal Processing (DSP systems. On the other hand, digit-serial architectures offer alternative low -complexity designs, since digit-serial operators occupy less area and are independent of the data wordlength. This paper introduces the problem of designing a digit-serial MCM operation with minimal area at gate-level and presents the exact formalization of the area optimization problem as a 0-1 Integer Linear Programming (ILP problem and introduces high level synthesis algorithms, design architectures, and a computer aided design tool. Results and Discussion show the efficiency of the proposed optimization algorithms and of the digit-serial MCM architectures in the design of digit serial MCM operations and finite impulse response filters.

  20. Exposure to radon in dwellings below the ground level in the area of Zagreb

    International Nuclear Information System (INIS)

    Radon measurements were carried out in 44 dwellings at 22 locations in the area of Zagreb with the aim of establishing possible differences in radon levels between dwellings located below ground level, and those on higher floors. The measurements were performed using a Honeywell professional radon monitor both during the spring/summer and the autumn/winter seasons. Significant differences were found: for dwellings below ground level, the average annual radon activity concentration was 57±20 Bqm-3; for those on higher floors the value was 35±15 Bqm-3. (A.K.)

    This study was carried out to determine the factors that influence farmers’ participation in social organizations in Obubra LGA in Cross River State. To achieve this, a multistage random sampling technique was used to select five out of 27 clans. Two local organizations were randomly selected from each of the five clans and finally 6 members were also randomly selected from each of the organization, resulting in a total of 60 respondents. The results indicate that half of the respondents (50% were young people (below 30 years and they were majority (93.3% Christians who mostly cultivate small farm holdings of less than 2ha. Majority (68.3 belonged to just one organization, while 20 percent belonged to two organizations. Majority (56.7% also earned less than N4,000 per month. The members joined local organizations basically for economic benefits and farm supports. Their participation was affected by mutual distrust among members and lack of confidence in their leadership. They were also not sure of having expected organizational benefits. Chi-square (χ2 test result indicated a significant relationship between farm size, educational level, income and participation (P>0.05; 56.0, 9.623 and 7.607. Organizational environment that will encourage effective participation should be encouraged by ensuring due enforcement of organisation’s code of conduct, rules and regulations. Local organizations should also be used as a channel to assist farmers in micro-credit and input delivery. This will be made possible by ensuring good organizational leadership.

    The Hanford Site, located adjacent to and north of Richland, Washington, is operated by the US Department of Energy, Richland Operations Office (RL). The 324 Building is located in the 300 Area of the Hanford Site. The 324 Building was constructed in the 1960s to support materials and chemical process research and development activities ranging from laboratory/bench-scale studies to full engineering-scale pilot plant demonstrations. In the mid-1990s, it was determined that dangerous waste and waste residues were being stored for greater than 90 days in the 324 Building Radiochemical Engineering Cells (REC) and in the High-Level Vault/Low-Level Vault (HLV/LLV) tanks. [These areas are not Resource Conservation and Recovery Act of 1976 (RCRA) permitted portions of the 324 Building.] Through the Hanford Federal Facility Agreement and Consent Order (Tri-Party Agreement) Milestone M-89, agreement was reached to close the nonpermitted RCRA unit in the 324 Building. This closure plan, managed under TPA Milestone M-20-55, addresses the identified building areas targeted by the Tri-Party Agreement and provides commitments to achieve the highest degree of compliance practicable, given the special technical difficulties of managing mixed waste that contains high-activity radioactive materials, and the physical limitations of working remotely in the areas within the subject closure unit. This closure plan is divided into nine chapters. Chapter 1.0 provides the introduction, historical perspective, 324 Building history and current mission, and the regulatory basis and strategy for managing the closure unit.

    Protected water curtain cultivation system is an energy saving technique for winter season by splashing groundwater on the inner roof of the green house. But the issue is that the method results in groundwater level deterioration because it disposes the used groundwater to nearby stream. Reuse of the groundwater for water curtain cultivation is important Groundwater level, steam level, and groundwater usage rate are investigated at the five green house concentrated areas such as Cheongwon, Namyangju, Choongju, Namwon, Jinju. Groundwater usage rate is estimated using a ultrasonic flowmeter for a specific well and using the combination of pressure sensor and propeller type velocity counting equipment at a water disposal channel from November to April which is water curtain cultivating season. Groundwater usage rate ranges from 46.9m3/d to 108.0m3/d for a 10a greenhouse. Groundwater level change is strongly influenced by seasonal variation of rainfall and concentrated pumping activities in winter but the level is lower than stream level all year long resulting in all year around losing stream at Cheongwon, Namyangju, Jinju. At Nanwon, the stream is converted from losing one in winter to gaining one in summer. Groundwater level deterioration at concentrated water curtain cultivation area is found to be severe for some area where circulating water curtain cultivation system is need to be applied for groundwater restoration and sustainable cultivation in winter. Circulating water curtain cultivation system can restore the groundwater level by recharging the used groundwater through injection well and then pumping out from pumping well.

    Objective: To evaluate the correlation of chronic periodontitis in tropical area and IFN-γ, IL-10 and IL-17 levels. Methods: One hundred and forty-eight patients and one hundred and thirty-two healthy control subjects were included in the study. Clinical parameters (PI, GI and PD) and GCF levels of IFN-γ, IL-10 and IL-17 were measured at baseline, week 8, week 16 and week 24 after mechanical removal of dental plaque. IFN-γ and IL-10 were determined with ELISA methods and IL-17 was determined with the cytometric bead array. Results: Removal of dental plaque resulted in improvement in all clinical parameters. Meanwhile, GCF IL-17 declined to control levels, while GCF IFN-γ and IL-10 levels remained unchanged. Conclusions: The decline of GCF IL-17 levels in patients with resolution of periodontitis suggests that IL-17 is involved in the periodontal inflammatory process.

    From the socio-economical analysis it appears that the Wadden Sea area has a low population density and a low growth of the population compared to other regions in the Netherlands. Also, employment is low and income is lower than in other parts of the Netherlands. Unemployment has decreased but is still higher than in the rest of the Netherlands. Next to an analysis of the present structure of the different sectors in the Wadden Sea region, a SWOT-analysis has been carried out and interviews were held with representatives of different sectors: industry and businesses, scientific institutes and societal organizations. Based on the results of the socio-economic analysis perspectives were developed for the following five sectors: industry, recreational sector and tourism, exploitation of energy sources and resources, agriculture and fisheries.

    Diabetes is an escalating problem in India and has major socioeconomic dimensions. Rapid dietary changes coupled with decreased levels of physical activity have resulted in increases in obesity and diabetes in rural and semi-urban areas, as well as in urban-based people living in resettlement colonies. Increasing risk has also been recorded in those who suffered from poor childhood nutrition and in rural-to-urban migrants. Social inequity manifests in disparities in socioeconomic status (SES), place of residence, education, gender, and level of awareness and affects prevention, care, and management. All these population subsets have major socioeconomic challenges: low levels of awareness regarding diabetes and prevention, inadequate resources, insufficient allotment of healthcare budgets, and lack of medical reimbursement. Unawareness and delays in seeking medical help lead to complications, resulting in many-fold increased costs in diabetes care. These costs plunge individuals and households into a vicious cycle of further economic hardship, inadequate management, and premature mortality, resulting in more economic losses. At the societal level, these are massive losses to national productivity and the exchequer. Overall, there is an immediate need to strengthen the healthcare delivery system to generate awareness and for the prevention, early detection, cost-effective management, and rehabilitation of patients with diabetes, with a focus on people belonging to the lower SES and women (with a particular focus on nutrition before and during pregnancy). Because of an enhanced awareness campaign spearheaded through the National Program on Prevention of Cardiovascular Disease, Cancer, Diabetes and Stroke (NCPCDS) initiated by Government of India, it is likely that the level of awareness and early detection of diabetes may increase.

  16. Socioeconomic trends in radiology

    International Nuclear Information System (INIS)

    For radiology the socioeconomic environment is a topic of increasing importance. In addition to the well-known important scientific developments in radiology such as interventional MRI, several other major trends can be recognized: (1) changes in the delivery of health care, in which all kinds of managed care are developing and will influence the practice of radiology, and (2) the process of computerization and digitization. The socioeconomic environment of radiology will be transformed by the developments in managed care, teleradiology and the integration of information systems. If radiologists want to manage future radiology departments they must have an understanding of the changes in the fields of economics and politics that are taking place and that will increasingly influence radiology. Some important and recognizable aspects of these changes will be described here. (orig.)

    A stochastic model is suggested to perform the space-time optimal analysis of the sea level data recorded in 1978-1982 at 20 stations at the Estonian coast and along a part of the Latvian coast surrounding the Gulf of Riga. The original time series recorded with the time lag of 1, 6 or 12 h are divided into mean and fluctuation components. The mean field is modeled as the sum of the linear trend and annual harmonic. The mean sea level is generally higher at the stations located in the river mouth area. The estimated linear trend yielding the sea level rise of 1-3 cm/year is an approximation of the interannual variability over the selected 5-year period. The dominating annual harmonic with amplitude of 20 cm describes 40-45% of the total variability of the time series of the monthly mean sea level values. The temporal and spatial correlations of the sea level fluctuation field were estimated on the basis of the suggested stochastic model. The correlation functions were approximated by Gaussian functions yielding the temporal correlation radius (e-folding scale) of about 10 days and spatial correlation radius of 200-400 nm. According to the developed criterion, proceeding from the suggested stochastic model, at least 90% of the sea level data from the Estonian coastal area should be considered as meeting the quality requirements. There was no significant difference in the quality of data measured either continuously by mareographs or observed by reading the bench sticks. After removal of outliers, the approach was utilized to reconstruct the sea level field in the Estonian coastal area in 1978-1982 with an acceptable low reconstruction error.

    The levels of cadmium, copper and nickel in five different edible vegetables, Talinum triangulare, Celosia trigyna, Corchorus olitorus, Venomia amygydalina and Telfaria accidentalis, and the soils in which they were grown, from three industrial and three residential areas of Lagos City, Nigeria, were determined using atomic absorption spectrophotometry. The results obtained for these three heavy metals from the industrial areas were higher than those of the residential areas as a result of pollution. Industrial area results for vegetables ranged between 1.13 and 1.67 microg/g for cadmium; 25.08 and 56.84 microg/g for copper and 1.33 and 2.06 microg/g for nickel. There were statistically significant differences (P<0.05) between the levels of copper and nickel in all the vegetables studied from industrial and residential areas, while there was no statistically significant difference for cadmium. The results also show that Corchorus olitorus (bush okra) has the ability to accumulate more copper and nickel than the other vegetable studied but has the least ability to accumulate cadmium.

This index showed that the Zhoukoudian area of Beijing was a moderate or marginal level selenium ecological landscape. The mean serum selenium level of the population was 75.01 {+-} 28.35 {mu}g/L, ranging between 35.2 and 160.4 {mu}g/L. A total of 279 (69.6%) individuals exhibited serum selenium level below 80 {mu}g/L, which is the lowest threshold for the activity of glutathione peroxidases (GPx) in vivo. A total of 35 (8.5%) individuals exhibited serum selenium level below 45 {mu}g/L. It is widely recommended that below this value (45 {mu}g/L) there is an increased risk of cardiovascular disease and cancer. Multiple linear regression analysis showed that serum selenium level was positively associated with body mass index ({beta} = 0.137; P = 0.011), serum total cholesterol TC ({beta} = 0.785; P = 0.000), however, negatively associated with systolic blood pressure ({beta} = - 0.172; P = 0.023), serum triglyceride ({beta} = - 0.170; P = 0.007), high density lipoprotein-cholesterol ({beta} = - 0.121; P = 0.027), and low high density lipoprotein-cholesterol ({beta} = - 0.568; P = 0.027)

  3. Study of Nox Levels At The Castellon Area (spain) By Means of Passive Samplers

    Science.gov (United States)

    Delgado, J. M.; Esteve, V.

    Nitrogen oxides are emitted by mobile sources like traffic, heating engines and indus- tries. In the case of La Plana de Castellon area, the cities, the industrial area called El Serrallo (with its oil refinery and power plant), the tile factories and the main roads (A7-E15 and N-340), all they are the main pollutant focus of NOx. Those pollutants are precursors of tropospheric ozone formation. The aim of this work is the study of nitrogen oxides levels in La Plana de Castellon area, by means of passive samplers and stand relationships between NOx levels and ozone levels both measured with pas- sive samplers. The measurement campaign is made during summer, the higher pho- tochemical activity period (from May to September) in order to obtain the necessary data of NOx levels to make the relationship with measured ozone levels. Measuring campaing has been divided into sampling periods of one week. Twelve samples are collected each sampling period to cover an interest area of 1400 Km2, Two of these samples are laboratory blanks, four are situated at reference points (beside an auto- matic NOx sampler), one is situated at A7-E15 expressway, other at the main road N-340 and another one in a hard traffic road. The other three are placed in the main cities (Castellon and Benicassim). We employ Radielloo samplers developed by Dr. Cocheo at Fondazione Salvatore Maugeri. Samples located far from the main roads, at countryside show the lowest levels of NOx, lower than 10 ppb. Samples located at Castellon city show a difference between downtown and boundaries of about 33% higher at downtown, raising from 11 ppb to 14,5 ppb of NOx. The highest levels of NOx are measured at roads and their surroundings with medium levels of 14,3 ppb of NOx. Moreover, the sample located close to the expressway raises its level until 18 ppb of NOx, 53,4% higher than the media of all the samples measured. We would like to thank Dr. M. Wolfson(Harvard University), Dr. Carlos Felis (Conselleria de

    Full Text Available OBJECTIVE: To assess the influence of socioeconomic background on malocclusion prevalence in primary dentition in a population from the Brazilian Amazon. METHODS: This cross-sectional study comprised 652 children (males and females aged between 3 to 6 years old. Subjects were enrolled in private preschools (higher socioeconomic status - HSS, n = 312 or public preschools (lower socioeconomic status - LSS, n = 340 in Belém, Pará, Brazil. Chi-square and binomial statistics were used to assess differences between both socioeconomic groups, with significance level set at P < 0.05. RESULTS: A high prevalence of malocclusion (81.44% was found in the sample. LSS females exhibited significantly lower prevalence (72.1% in comparison to HSS females (84.7%, particularly with regard to Class II (P < 0.0001, posterior crossbite (P = 0.006, increased overbite (P = 0.005 and overjet (P < 0.0001. Overall, malocclusion prevalence was similar between HSS and LSS male children (P = 0.36. Early loss of primary teeth was significantly more prevalent in the LSS group (20.9% in comparison to children in the HSS group (0.9%, for both males and females (P < 0.0001. CONCLUSION: Socioeconomic background influences the occurrence of malocclusion in the primary dentition. In the largest metropolitan area of the Amazon, one in every five LSS children has lost at least one primary tooth before the age of seven.

    Full Text Available Aim: To measure and assess the noise levels produced by different dental equipments. Materials and Methods: Measurement of the noise level was performed in preclinics, clinics, and dental laboratory of different departments of Ahmedabad Dental College and Hospital. The noise levels were determined using a Mini sound meter (CEM USA, which was placed at the dentist′s and laboratory technician′s ear level and at a distance of 1 m from a main noise source. The level of noise was measured in decibel (dB while the instruments were at maximum running speed. Results: In dental laboratory, the nosiest dental equipment was gypsum lathe trimmer with the noise level ranging from 87.36 to 98.3 dB. In preclinical area, the sound produced by low-speed air-rotor ranges from 66.68 to 69.28 dB. In clinical areas, the highest noise produced was by high-speed air-rotor (73.36 to 81.8 dB. The noise created by suction pump when in contact with mucosa was in range from 73.1 to 80.32 dB. The noise levels generated during cutting were significantly higher (P < 0.05 than those of noncutting, which was proved in the course of the measurements. Conclusion: At the end of the study it can be concluded that the sound levels are below that causes damage to the human ear (85 dB. However, dental technicians and other personnel working all day in noisy laboratories could be at risk of Noise-Induced Hearing Loss if they did not choose not to wear ear protection.

    Park, Yoonkyung; Jun, Hwandon; Kim, Sangdan

    2015-04-01

    In this presentation, an indicator-based model is proposed to quantify socio-economic damage under natural disaster in Seoul, Korea. Seoul is the highest population density in Korea. Scales of the model are divided into two classes. First scale is "borough", which is town, or a district with a large town, and has its own council. In the case of Seoul, average size of boroughs is 24.28 square kilometers. Second one is "census output area", which is the finest level of statistical information. Average size of census output area in Seoul is 0.0374 kilometers. The Census output area has high resolution than boroughs. For the purpose of considering various aspects on socio-economic vulnerability under natural disaster, the proposed socio-economic vulnerability assessment model is composed of demographic/social indicator, economic indicator, and prepare/response/recovery indicator. Each of them is consist of 5, 3, and 6 proxy variables, respectively. Using the suggested model, the socio-economic vulnerability for 25 boroughs and 16,230 census output areas of Seoul is assessed. As a result, it is shown that southeastern boroughs in Seoul (Gangnam and Seocho) have lower vulnerability scores than other boroughs. According to this results, these places are much safer than other regions under natural disaster. Additionally, the socio-economic vulnerability was assessed in scale of census output data. Socio-economic vulnerability scores are shown similar results comparing with results of borough scale. However, socio-economic vulnerability scores are calculated in higher resolution. These results are caused by different demographic and social factors in each census output area even census output areas are located same borough. The additional importance of vulnerability assessment in the scale of census output areas will be presented.

    The present paper is concerned with the analytical and numerical investigation of the transverse spatio-temporal instabilities in two-level broad-area lasers for the specific class-B case. We show that the two-level class-B broad-area laser tends to naturally operate in the filamentary state. This is revealed to be provided with two causes. First of them is related with the homogeneous output profile being intrinsically unstable due to the traveling-wave instability, independently from the boundary conditions. Secondly, high sensitivity to the boundaries of the pumping region was found for the commonly used top-hat-like profile leading to boundaries-induced filamentary dynamics. Spatio-temporal properties of both instability mechanisms are studied and their effects on the resulting laser dynamical behavior are analyzed.

  15. Evaluation of environmental tritium level in the area of Cernavoda Nuclear Power Plant

    International Nuclear Information System (INIS)

    This work is a continuation of the study entitled Evaluation of environmental tritium levels before and after start of a new tritium source for model verification' that commenced two years ago as part of an European research contract having as objective the 'Investigations and Modelling of the Dynamics of Environmental HT/HTO/OBT Levels Resulting from the Tritium Releases'. The aim of this study was to evaluate the environmental tritium level in pre-operational stage of Cernavoda Nuclear Power Plant and the dynamics of variation of tritium concentration in the first operational years of NPP, for determination of site-specific transfer parameters and model validation. Representative samples for Cernavoda area were analyzed; - air humidity; - water from Danube River, Danube-Black Sea Canal and lakes; - drinking, rain and snow water; - HTO concentration in soils at different depths; - tissue free water tritium in vegetal and animal foodstuffs relevant for human diets like cereals (wheat, maize, barley). vegetables (potatoes, tomato, cabbage, onion, bean), grapes and wine. The mean concentration of tritium obtained in 1996 for these types of measurements is presented. The values of tritium concentration in air, water, soil and plants are as low as for areas without contaminating sources. The operation in 1996 of the Cernavoda NPP did not modify the tritium environmental level. (authors)

    Objective To investigate socioeconomic inequalities in outcome of pregnancy associated with Down syndrome (DS) compared with other congenital anomalies screened for during pregnancy. Design and setting Retrospective population-based registry study (East Midlands & South Yorkshire in England). Participants All registered cases of DS and nine selected congenital anomalies with poor prognostic outcome (the UK Fetal Anomaly Screening Programme (FASP)9) with an end of pregnancy date between 1 January 1998 and 31 December 2007. Main outcome measures: Poisson regression models were used to explore outcome measures, including socioeconomic variation in rates of anomaly; antenatal detection; pregnancy outcome; live birth incidence and neonatal mortality. Deprivation was measured using the Index of Multiple Deprivation 2004 at super output area level. Results There were 1151 cases of DS and 1572 cases of the nine severe anomalies combined. The overall rate of antenatal detection was 57% for DS, which decreased with increasing deprivation (rate ratio comparing the most deprived tenth with the least deprived: 0.76 (0.60 to 0.97)). Antenatal detection rates were considerably higher for FASP9 anomalies (86%), with no evidence of a trend with deprivation (0.99 95% CI (0.84 to 1.17)). The termination of pregnancy rate following antenatal diagnosis was higher for DS (86%) than the FASP9 anomalies (70%). Both groups showed wide socioeconomic variation in the termination of pregnancy rate (rate ratio: DS: 0.76 (0.58 to 0.99); FASP9 anomalies: 0.80 (0.65 to 0.97)). Consequently, socioeconomic inequalities in live birth and neonatal mortality rates associated with these anomalies arise that were not observed in utero. Conclusions Socioeconomic inequalities exist in the antenatal detection of DS, and subsequent termination rates are much higher for DS than other anomalies. Termination rates for all anomalies are lower in more deprived areas leading to wide socioeconomic inequalities in

    2011-11-01

    Recently, total assets have become a popular method to capture socioeconomic status (SES) for health research/intervention done in developing countries. Although, this method is suitable for areas in a rural setting, there are 2 major issues in applying this method: (a) which durable assets/infrastructure or housing characteristics truly reflect the family SES and (b) how to aggregate different variables to get a derived index of SES and produce a range of critical points differentiating socioeconomic levels. This study aims to validate the use of total asset as proxy for SES by addressing these issues. Results indicated that (a) variables reflecting family SES in rural setting area include variables capturing access to utilities and infrastructure, housing characteristics, and durable asset ownership; (b) principal component analysis is a suitable method to construct a derived index from multiple variables; and (c) the derived index is a valid indicator for SES in rural setting area.

    2015-06-01

    Full Text Available Sustainable development-related issues have been discussed in the public discourse worldwide since the 1960’s. The socioeconomic development theme is one of the key themes in sustainable development singled out by the European Union with a special attention paid to three crucial areas, namely: economic development, competitiveness, innovation and eco-efficiency as well as employment. Therefore, the aim of this article is to assess the implementation level of the sustainable development concept in the area of socioeconomic development in Poland compared to other Member States. In order to achieve the articles aim the following two research tasks were performed: sustainable development in terms of socioeconomic development in the EU strategic documents has been described and the sustainable development concept in the area of socioeconomic concept in Poland compared to other Member States has been analysed. The analysis showed that the gap between Poland and the ‘old’ EU has been narrowed since 2004; however, the progress in implementing the sustainable development concept into socioeconomic development was still slow comparing to both the EU-10 and EU-15. This article is based on the available reference, government documents and the analysis was conducted on the basis of secondary data provided by Eurostat.

    The analysis of mercury, cadmium and lead in water samples from different environments (Lake Naivasha, River Malewa boreholes and Olkaria geothermal wells) in Naivasha region and their possible origins are reported. The levels of mercury and lead in the water samples were above the maximum permissible limits of 0.005 mg/1 and 0.1 mg/1 respectively, as stipulated by the WHO. On the other hand, 83.3% of the samples had cadmium levels above the maximum permissible limit of 0.01mg/1 in drinking water by WHO. The mercury and lead levels were also higher than those previously obtained from different regions of Kenya, while those for cadmium were within the corresponding range. Possible sources of elevated values were the geology of the surrounding area, sewage treatment works, use of phosphate rock fertilizers and lead fuels.(author)

  3. Thyroid status and urinary iodine levels in women of endemic goiter area

    International Nuclear Information System (INIS)

    Background: To determine the thyroid function tests and urinary iodine levels in women belonging to goiter endemic area. Study type and settings: Descriptive study conducted in women of goiter endemic area in Saggian Lahore. Subjects and Methods: Saggian Lahore is a goiter endemic area. A total of 293 women between the ages of 18-45 years residing in the area were clinically screened for goiter. Of them 73 women having goiter were recruited for the study. Information regarding demographic profile clinical presentation and physical examination of the goiter was recorded on a questionnaire. The goiter size was graded according to WHO, UNICEF and the International Council for the Control of Iodine Deficiency Disorder. About 5ml of blood sample was drawn from each women and run for thyroid function tests i.e. T3 T4 and TSH using Elisa kits (Human scientific Co. Germany). Urinary iodine was checked by chemical method. Results: Mean age of 73 women was 28.5 years. Marital status showed that 48(65.7%) were married and 25(34.3%) were unmarried. Visible diffuse goiter was seen in 56(77%) cases. Pressure symptoms as cough and shortness of breath was seen in 30(41%) and 31(42.5%) women respectively. Among the 73 women 24.6% (18 cases) took treatment for goiter. Adverse pregnancy outcome secondary to goiter was seen in 58% (28 cases) out of 48 married women. Thyroid function tests result showed that 72% (53 cases) were euthyroid, 18% (13 cases) were hypothyroid, and 10% (7 cases) were hyperthyroid. Urinary iodine levels showed that 99% women were iodine deficient. Conclusions: Thyroid functions do not indicate iodine deficiency in all cases of goiter, therefore, Urinary iodine levels need be estimated while investigating goiter cases. Policy message: Iodine deficiency should be diagnosed and treated on priority basis. (author)

    1985-07-01

    All areas of practice in hospital dietetic services include a management component; however, the nature of the managerial role in various areas of dietetic practice has not been identified clearly. The definition of dietetic practice in the Conceptual Framework for the Profession of Dietetics supports the importance of managerial skills. The effect of organizational level and practice area on managerial activities and roles of professional staff in hospital dietetic services was examined in this study. The nationwide sample included professionals in hospitals with 300+ beds. A total of 3,280 dietetic professionals participated. Five groups were defined: low administrative, low clinical, middle administrative, middle clinical, and upper administrative. Mintzberg identified 10 managerial roles and categorized them as interpersonal, informational, or decisional. The 10 roles were used as the basis for developing an 80-item instrument on which respondents rated each item for importance and time demand. Perceived importance of managerial activities tended to be greater at higher organizational levels. The managerial aspects of the lower clinical and upper administrative position were the most clearly defined. The lower clinical group tended to rate all of the managerial roles as significantly less important than did those in other positions; however, the middle clinical position included a substantial managerial responsibility.

  7. Predicting fuel poverty at a small-area level in England

    International Nuclear Information System (INIS)

    This paper describes the development of a series of models for predicting the incidence of fuel poverty in England at a small-area level and examines the adequacy of the modelled results in informing our understanding of the geography of fuel poverty. This paper summarises the development of alternative approaches to model specification based upon different approaches to the treatment of household income. Since 2003 small-area fuel poverty estimates have been widely used to inform affordable warmth policies and local targeting of fuel poverty programs. Whilst improvements in data sources and methods in recent years provide an opportunity to better understand the spatial distribution of fuel poverty, these analyses suggest that our understanding of the incidence and spatial distribution of fuel poverty is highly sensitive to the way in which household incomes are measured. - Highlights: → The proposed models estimate fuel poverty incidence at a small-area level. → This is necessary in order to accurately target local fuel poverty interventions. → Fuel poverty estimates are highly sensitive to differences in income measurement. → Fewer children and more pensioners are fuel poor using EHCS income measures. → More children and fewer pensioners are fuel poor using HBAI income measures.

    International Nuclear Information System (INIS)

    The objective of this study was to detect the selenium level in the environment and the population of Zhoukoudian area, Beijing, and to discuss the influence of various factors on serum selenium level. The soil, drinking water, and foodstuff samples and venous blood samples of 401 individuals were obtained to determine the selenium level by gas chromatograph equipped with a 63Ni electron capture detector (ECD). The selenium level was 0.210 ± 0.013 μg/g in soil, 0.017 μg/L ± 0.002 in drinking water, 0.034 ± 0.002 μg/g in rice, and 0.034 ± 0.012 μg/g in wheat flour. This index showed that the Zhoukoudian area of Beijing was a moderate or marginal level selenium ecological landscape. The mean serum selenium level of the population was 75.01 ± 28.35 μg/L, ranging between 35.2 and 160.4 μg/L. A total of 279 (69.6%) individuals exhibited serum selenium level below 80 μg/L, which is the lowest threshold for the activity of glutathione peroxidases (GPx) in vivo. A total of 35 (8.5%) individuals exhibited serum selenium level below 45 μg/L. It is widely recommended that below this value (45 μg/L) there is an increased risk of cardiovascular disease and cancer. Multiple linear regression analysis showed that serum selenium level was positively associated with body mass index (β = 0.137; P = 0.011), serum total cholesterol TC (β = 0.785; P = 0.000), however, negatively associated with systolic blood pressure (β = - 0.172; P = 0.023), serum triglyceride (β = - 0.170; P = 0.007), high density lipoprotein-cholesterol (β = - 0.121; P = 0.027), and low high density lipoprotein-cholesterol (β = - 0.568; P = 0.027)

    Purpose and Scope In 1969, hydrologic data-collection sites were established in and around the Coconut Grove area for the purpose of measuring directly the relationship between rainfall, runoff, ground-water levels, the level of water in Kawainui Swamp and the canals, and tidal fluctuations. The primary objective was to identify the causes of the occurrence and persistence of flooding and to gain data on which to base recommendations for remedial action. The scope of the study included establishing and operating flow and stage-recording gages on the Swamp, Kawainui Canal, and the inner canal; periodic and repeated measurements of ground-water level in test borings throughout the residential area; collection and analysis of soil and construction borings made for engineering purposes; the assembly and analysis of all available data relating surface and subsurface flow conditions, and the development of conclusions as to the causes and means to alleviate the flooding. This report summarizes the information collected from October 1969 to June 1971, includes analysis of the data, and discusses the probable causes of flooding.

  10. Increased indoor Rn levels due to actinide containing mineral collections displayed in living areas

    International Nuclear Information System (INIS)

    Collection of crystals ranging from quartz to U or Th containing minerals is a widespread spare time activity in Switzerland. Radon emanation from stones displayed in showcases in the living area may contribute considerably to elevated Rn levels in the indoor air. Time-averaged Rn gas measurements in 35 homes of subscribers to a journal for mineral collectors showed an unexpected statistically significant increase of 98 Bq m-3 in the Rn level of the room containing the collections compared to the levels measured in a control room on the same floor. Using ICRP Publication 50 conversion factors for indoor exposure to Rn decay products, the additional effective dose equivalent contracted was estimated to amount to an average of 2.7 mSv y-1. Although the 220Rn emanation rate, as measured in the display cases, was considerable in several cases, the dose from 220Rn decay products in the living area remained always a small fraction of the Rn dose. Remedial actions for crystal collections containing considerable amounts of U- or Th-based minerals are suggested

    This Performance Assessment for the Savannah River Site E-Area Low-Level Waste Facility was prepared to meet requirements of Chapter IV of the Department of Energy Order 435.1-1. The Order specifies that a Performance Assessment should provide reasonable assurance that a low-level waste disposal facility will comply with the performance objectives of the Order. The Order also requires assessments of impacts to water resources and to hypothetical inadvertent intruders for purposes of establishing limits on radionuclides that may be disposed near-surface. According to the Order, calculations of potential doses and releases from the facility should address a 1,000-year period after facility closure. The point of compliance for the performance measures relevant to the all pathways and air pathway performance objective, as well as to the impact on water resources assessment requirement, must correspond to the point of highest projected dose or concentration beyond a 100-m buffer zone surrounding the disposed waste following the assumed end of active institutional controls 100 years after facility closure. During the operational and institutional control periods, the point of compliance for the all pathways and air pathway performance measures is the SRS boundary. However, for the water resources impact assessment, the point of compliance remains the point of highest projected dose or concentration beyond a 100-m buffer zone surrounding the disposed waste during the operational and institutional control periods. For performance measures relevant to radon and inadvertent intruders, the points of compliance are the disposal facility surface for all time periods and the disposal facility after the assumed loss of active institutional controls 100 years after facility closure, respectively. The E-Area Low-Level Waste Facility is located in the central region of the SRS known as the General Separations Area. It is an elbow-shaped, cleared area, which curves to the northwest

    The present editorial discusses whether socioeconomic status of the individual and of the neighbourhood could be important in prevalence, treatment and prevention of psychiatric morbidity. Previous research showed that patients diagnosed with mental disorders are concentrated in socioeconomically disadvantaged areas. This could be the result of (1) an association between individual socioeconomic status and mental health, (2) an association between neighbourhood socioeconomic status and mental health, or (3) social selection. Research disentangling associations between individual and neighbourhood socioeconomic status on the one hand and mental health outcomes on the other, reported that neighbourhood socioeconomic disadvantage was associated with individual mental health over and above individual-level socioeconomic status, indicating deleterious effects for all inhabitants both poor and affluent. In conclusion, subjective mental health outcomes showed stronger evidence for an effect of neighbourhood socioeconomic status than research focussing on treated incidence. Within the group of patients, however, service use was higher in patients living in disadvantaged neighbourhoods. Social capital was identified as one of the mechanisms whereby neighbourhood socioeconomic disadvantage may become associated with observed reductions in mental health. After controlling for individual socioeconomic status, there is evidence for an association between neighbourhood socioeconomic status and objective as well as subjective mental health in adults. Evidence for such an association in young children is even stronger. PMID:17427598

    Full Text Available Rural population ageing and decline is a serious problem throughout Europe resulting in a deterioration of the socioeconomic situation in rural areas. This leads to land abandonment, and consequently the loss of valuable cultural landscapes. Protected areas are no exception and inhabitants also face restrictions arising from the protection status. The aim of this study is to identify the existence, extent and nature of the socioeconomic impacts derived from the protection status on the local population. Population and socioeconomic indicators were compared with the results of in-depth interviews with local stakeholders within 2 Estonian national parks and contextualised with recent social change. It was concluded that protected areas have a considerable socioeconomic impact and in order to preserve cultural landscapes, achieve conservation objectives and contribute to balanced regional development, measures must be taken.

    Objective To oberve the change in blood glutathione peroxidase (GSH-Px) protein levels of residents in the low-selenium (Se) area by contrasting the blood GSH-Px protein level of the children in the Keshan disease area with those in the Kashin-Beck disease and non-endemic areas. Methods GSH-Px protein levels were measured by enzyme-linked immunosorbent assays (ELISA). The Se content and GSH-Px activity were assayed by the 2,3-diaminonaphthalene spectrofluorimetric method and glutathione reductase-coupled method respectively. Results ①The blood Se content and GSH-Px protein level of children in Keshan disease area (Moding) were significantly lower than those in Xi'an non-endemic area, however, there was no significant difference when compared with the low-Se non-endemic area; ②The blood Se content, GSH-Px activity and GSH-Px protein level of children in the Kashin-Beck disease area (Yulin) were significantly lower than those of children in two non-endemic areas and in the Keshan disease area; ③The blood Se content and GSH-Px activity were positively correlated to the GSH-Px protein level respectively. Conclusion These results indicate that the blood GSH-Px protein level is decreased in the low-Se residents. The Se status not only affects the GSH-Px activity but also regulate the GSH-Px protein level.

    2016-04-01

    The European Water Framework Directive (WFD 2000/60/CE) requires Member States to evaluate the status of groundwater bodies in order to reach a good water quality for human consumption. One of the preliminary steps for defining the status of groundwater bodies consists in the definition and evaluation of the so-called Natural Background Levels (NBL). The NBL or Baseline level can be defined as "the range of concentration of a given element, isotope or chemical compound in solution, derived entirely from natural, geological, biological or atmospheric sources, under conditions not perturbed by anthropogenic activity" (Edmund and Shand, 2009). The qualitative analysis for a large area (ca 4500 Km2) of the Po Plain around the Milan Metropolitan area (Lombardy, Italy) is presented in this study. Despite the aquifers in the Milan metropolitan area are an incredible groundwater resource for a very large population (3.195.629 inhabitants in the metropolitan area, data at November 2014) and a highly industrialized area, a groundwater baseline characterization is still missing. In order to attain the hydro-geochemical characterization a complete geodatabase was built (120.655 chemical samples from 1980 to 2014). This database has been explored by classical and multivariate statistical analyses to provide relationships among the more influential lithological, hydrogeological and hydro-chemical variables. Finally, the NBLs of different chemical species which may be anthropogenic sensitive (Na, Cl, K, NO3, SO4, NH4, As, Fe, Cr, Fe, Mn, Zn) and for multiple aquifer bodies (phreatic, semi-confined and confined aquifer) are evaluated. Two different approaches are applied: the Pre-Selection method (BRIDGE, 2006) and the Component-Separation method. The first one (PS) consists in the exclusion of samples from the available dataset that could indicate human activities then deriving the NBL as the 90th percentile of the remaining data. The second one (CS) consists in the fitting of

  1. Energy requirements and physical activity level of active elderly people in rural areas of cuba

    International Nuclear Information System (INIS)

    Obesity and non-insulin dependent diabetes mellitus (NIDDM) are common in the Third Age and increasing in Cuba. Among the life-style changes associated with increased prevalence of obesity and its related disorders, diet and activity patterns are prime candidates. The transition to this life-style model may induce a decrease in the energy needs. There is an urgent need for tools which have been validated for measuring diet and physical activity in nutritional studies in the developing world, but also a more urgent need for reference values for the total energy requirements of healthy elderly people. Regular physical activity reduces the likelihood to develop diseases that characterise the metabolic cardiovascular syndrome. Previous studies done in Havana showed values of physical activity level (PAL) which are lower than the reported for elderly subjects. Elderly people living in rural areas use to have physical activity levels which differ from the observed in urban areas. With the purpose of estimating the energy requirements, a group of 40 apparently healthy people older than 60 years of age living in a rural mountain community will be submitted to a medical, epidemiological, dietary, anthropometric and insulin resistance study. Physical activity will be determined by questionnaire and by the calculation of the PAL from the basal metabolic rate (BMR) and total energy expenditure (TEE) measured with the doubly-labelled water method (DLW). Associations with the prevalence of insulin resistance and obesity will be assessed. (author)

    2015-10-01

    Full Text Available Graphene sheets doped with nitrogen were produced by the reduction-expansion (RES method utilizing graphite oxide (GO and urea as precursor materials. The simultaneous graphene generation and nitrogen insertion reactions are based on the fact that urea decomposes upon heating to release reducing gases. The volatile byproducts perform two primary functions: (i promoting the reduction of the GO and (ii providing the nitrogen to be inserted in situ as the graphene structure is created. Samples with diverse urea/GO mass ratios were treated at 800 °C in inert atmosphere to generate graphene with diverse microstructural characteristics and levels of nitrogen doping. Scanning electron microscopy (SEM and transmission electron microscopy (TEM were used to study the microstructural features of the products. The effects of doping on the samples structure and surface area were studied by X-ray diffraction (XRD, Raman Spectroscopy, and Brunauer Emmet Teller (BET. The GO and urea decomposition-reduction process as well as nitrogen-doped graphene stability were studied by thermogravimetric analysis (TGA coupled with mass spectroscopy (MS analysis of the evolved gases. Results show that the proposed method offers a high level of control over the amount of nitrogen inserted in the graphene and may be used alternatively to control its surface area. To demonstrate the practical relevance of these findings, as-produced samples were used as electrodes in supercapacitor and battery devices and compared with conventional, thermally exfoliated graphene.

    The total mercury (T-Hg) and methyl mercury (Me-Hg) concentrations in the hair were measured to evaluate mercury (Hg) exposure for the residents in Da-shui-xi Village (DSX) and Xia-chang-xi Village (XCX) in the Wanshan Hg mining area, Guizhou Province, Southwestern China. The mean concentrations in the hair of DSX residents were 5.5 ± 2.7 μg/g and 1.9 ± 0.9 μg/g for T-Hg and Me-Hg, respectively. The concentrations in the hair of XCX residents were 3.3 ± 1.4 μg/g and 1.2 ± 0.5 μg/g for T-Hg and Me-Hg, respectively. Hair Me-Hg concentrations were significantly correlated to T-Hg (r = 0.42, P < 0.01) in the two sites; on average, hair Me-Hg concentration accounted for 40 and 44% of T-Hg for DSX and XCX residents, respectively. Age has no obvious correlation with hair Hg and the hair Hg levels showed a significant gender difference, with higher T-Hg and Me-Hg concentrations in the hair from males than females. The rice collected from the two sites showed high levels of T-Hg and Me-Hg concentration. The results indicated a certain Hg exposure for the residents in DSX and XCX in the Wanshan Hg mining area.

  4. Extended storage of low-level radioactive waste: potential problem areas

    International Nuclear Information System (INIS)

    If a state or state compact does not have adequate disposal capacity for low-level radioactive waste (LLRW) by 1986 as required by the Low-Level Waste Policy Act, then extended storage of certain LLRW may be necessary. In this report, extended storage of LLRW is considered in order to determine for the Nuclear Regulatory Commission areas of concern and actions recommended to resolve these concerns. The focus is on the properties and performance of the waste form and waste container. Storage alternatives are considered in order to characterize the likely storage environments for these wastes. The areas of concern about extended storage of LLRW are grouped into two categories: (1) Performance of the waste form and/or container during storage, e.g., radiolytic gas generation, radiation-enhanced degradation of polymeric materials, and corrosion. (2) Effects of extended storage on the properties of the waste form and/or container that are important after storage (e.g., radiation-induced embrittlement of high-density polyethylene and the weakening of steel containers resulting from corrosion). A discussion is given of additional information and actions required to address these concerns

  5. Major congenital malformations in the high and normal level radiation areas of southwest coast of Kerala

    International Nuclear Information System (INIS)

    Congenital malformations are defects in organogenesis during the fetal periods and its influence on the individual may vary according to the type of malformation. Some congenital malformations are trivial and may not have any significance but for a minimal cosmetic deformity. Major malformations on the contrary may be severe enough to be life-threatening with serious structural, functional or cosmetic disability requiring surgical or medical management and are an important cause of mortality and morbidity all over the world. The present paper analyses the major malformations detected during the monitoring of newborns in selected government hospitals in and around the high level natural radiation areas of Kerala, a narrow strip of land in the southwest coast extending from Purakkad panchayat of Alapuzha district in the north to Neendakara Panchayat of Quilon district in the south. The coastal area has natural deposits of Monazite sand containing Thorium. Thorium together with its daughter products accounts for the elevated levels of natural radiation. The finding in general was in conformity with similar works on malformations

  6. Reef Fishes at All Trophic Levels Respond Positively to Effective Marine Protected Areas.

    Directory of Open Access Journals (Sweden)

    German A Soler

    Full Text Available Marine Protected Areas (MPAs offer a unique opportunity to test the assumption that fishing pressure affects some trophic groups more than others. Removal of larger predators through fishing is often suggested to have positive flow-on effects for some lower trophic groups, in which case protection from fishing should result in suppression of lower trophic groups as predator populations recover. We tested this by assessing differences in the trophic structure of reef fish communities associated with 79 MPAs and open-access sites worldwide, using a standardised quantitative dataset on reef fish community structure. The biomass of all major trophic groups (higher carnivores, benthic carnivores, planktivores and herbivores was significantly greater (by 40% - 200% in effective no-take MPAs relative to fished open-access areas. This effect was most pronounced for individuals in large size classes, but with no size class of any trophic group showing signs of depressed biomass in MPAs, as predicted from higher predator abundance. Thus, greater biomass in effective MPAs implies that exploitation on shallow rocky and coral reefs negatively affects biomass of all fish trophic groups and size classes. These direct effects of fishing on trophic structure appear stronger than any top down effects on lower trophic levels that would be imposed by intact predator populations. We propose that exploitation affects fish assemblages at all trophic levels, and that local ecosystem function is generally modified by fishing.

    conceptual model bearing  a hypothesis and five propositions closely linked to empirical evidence.The answer to the main research question is that the built environment is a catalyst for innovation in technology campuses demonstrated by location decisions and interventions facilitating five interdependent conditions required for innovation. The following propositions explain how the built environment facilitates each of the five conditions for innovation:Location decisions and area development facilitate the long-term concentration of innovative organisations in cities and regions.Interventions enabling the transformation of the built environment at area and building levels facilitate the climate for adaptation along changing technological trajectories over time.Large-scale real estate interventions facilitate the synergy among university, industry and governments.Location decisions and interventions supporting image and accessibility define the innovation area by emphasising its distinct identity, scale and connectivity features.Real estate interventions enabling access to amenities increase the diversity of people & chances for social interaction regardless the distinct geographical settings in which the concentration of innovative activities takes place.This research acknowledges that the location decisions of some technology-driven organisations have coincidentally determined the concentration of innovative research activities in  particular  places.  Over the years, the accommodation of  the  research  activities  of  these  organisations  has  co-  evolved  with  particular socio-economic processes in their hosting cities creating unique conditions for innovation. The concentration of innovative organisations can be considered as  a  primal  condition enabling the co-existence of the other four conditions for innovation. Similarly,  this  research acknowledges the following interventions facilitating conditions for innovation at the area level and

    Full Text Available Dioxin is an industrial pollutant related to various diseases, but epidemiological data on its effects on the kidney are limited. Therefore, we conducted a study to evaluate the association between dioxin exposure and chronic kidney disease (CKD and identify the related factors.We conducted a community-based cross-sectional study and recruited participants from an area where the residents were exposed to dioxin released from a factory. We defined a "high dioxin level" as polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs ≥ 20 pg WHO98-TEQDF/g lipid in the serum and defined CKD as having an estimated glomerular filtration rate (e-GFR ≤ 60 mL/min/1.73m2 or a diagnosis of CKD by a physician. The renal function was assessed between 2005 and 2010, and we excluded those who had had kidney diseases before the study started. Comparisons between patients of CKD and those who did not have CKD were made to identify the risk factors for CKD.Of the 2898 participants, 1427 had high dioxin levels, and 156 had CKD. In the univariate analyses, CKD was associated with high dioxin levels, age, gender, metabolic syndrome, diabetes mellitus, hypertension, and high insulin and uric acid levels. After adjusting for other factors, we found high dioxin levels (adjusted odds ratio [AOR] = 1.76, 95% confidence interval [CI]: 1.04-2.99, female gender (AOR = 1.74, 95%CI: 1.20-2.53, hypertension (AOR = 1.68, 95%CI: 1.17-2.42, high insulin levels (AOR = 2.14, 95% CI: 1.26-3.61, high uric acid levels (AOR = 4.25, 95% CI: 2.92-6.20, and older age (AOR = 4.66, 95% CI: 1.87-11.62 for 40-64 year and AOR = 26.66, 95% CI: 10.51-67.62 for age ≥ 65 year were independent predictors of CKD.A high dioxin level was associated with an increased prevalence of CKD. Therefore, the kidney function of populations with exposure to dioxin should be monitored.

    Objective To evaluate levels of lead (Pb) and cadmium (Cd) in the breast milk in the second post-partum month,to investigate the relationship between Pb/Cd levels in breast milk and some sociodemo-graphic parameters,and to explore whether these levels affect the infants' physical status or the mothers' psychological status (postpartum depression). Methods A cross-sectional study was conducted between November 2009 and December 2010. Al-together 170 healthy mothers were enrolled from Nanjing Maternity and Child Health Care Hospital. The inclusion criteria were: voluntary to participate in this study,healthy,with no chronic disease,breastfeeding in the second postpartum month,living in a suburban but not non-industrial area of Nanjing,and not occupa-tionally exposed to toxic metals. All the mothers completed a questionnaire and were evaluated based on the Edinburgh Postpartum Depression Scale (EPDS) to identify the risk of postpartum depression. Pb and Cd levels in breast milk were determined by inductively coupled plasma mass spectroscopy. The infants of these mothers were examined for their z scores of weight for age,length for age,head circumference for age,and body mass index for age. Results The median breast milk levels of Pb and Cd were 40.6 μg/L and 0.67 μg/L,respectively. In 164 (96.5%) of the 170 samples,Pb levels were higher than the limit reported by the World Health Or-ganization (> 5 μg/L). Breast milk Cd level was > 1 μg/L in 54 (31.8%) mothers. The mothers with a his-tory of anemia had a higher breast milk Pb level than those without a history of anemia (41.1 μg/L vs. 37.9 μg/L,P = 0.050). The median breast milk Cd level in those who were active and passive smokers dur-ing pregnancy was significantly higher than that in non-smokers (0.88 μg/L vs. 0.00 μg/L,P = 0.025). The breast milk Cd level in the mothers not taking iron and vitamin supplements for 2 months postpartum was higher than in those taking the supplements (iron supplement: 0.74

    In recent years there has been an increasing awareness of the radiological impact of non-nuclear industries that extract and/or process ores and minerals containing naturally occurring radioactive material (NORM). Without radiological rules, these industrial activities may result in significant radioactive contamination of installations and sites. Depending on the potential hazardous to the environment and public health, the radioactive contaminated sites may require remediation. The extent of the site cleanup is a function of the size, localization, complexity, potential risks and on possible future uses envisioned for the site. Since worker and public health, public anxiety and economics factors are involved; the selection of an appropriate dose level can be quite complicated. This paper discusses the selection of a dose level criterion to remedy a site, which was contaminated by wastes from monazite processing. The site is located in the Sao Paulo city; the most densely populated Brazilian City. In its 60,000 square meters of area, a preliminary survey showed contaminated zones covering an area of 6,500 square meters. In some places, contamination was found below the superficial layer of the soil, being the radionuclide vertical distribution not uniform. The 228 Ra soil activity concentration reached values up to 33,000 Bq/kg while those for 226 Ra reached values up to 6,700 Bq/kg. Based on pathway analysis model and considering both the current land use and a hypothetical residential scenario, the residual contamination levels of radionuclides in soil have been derived for dose values of 10 mSv/y (dose level for intervention), 5 mSv/y, 3 mSv/y, 1 mSv/y (dose limit for practices) and 0.3 mSv/y (dose constraint for practices). An optimized value o f annual dose of about 5 mSv/y would be a good option for intervention level, but taking into account the public concern and anxiety, the site location and size, and the remediation costs, it is suggested the

    Flood risk and sea level rise impacts were assessed for the Port Authority of New York and New Jersey (PANYNJ) at four airports in the New York City area. These airports included John F. Kennedy International, LaGuardia, Newark International, and Teterboro Airports. Quantifying both present day and future flood risk due to climate change and developing flood mitigation alternatives is crucial for the continued operation of these airports. During Hurricane Sandy in October 2012 all four airports were forced to shut down, in part due to coastal flooding. Future climate change and sea level rise effects may result in more frequent shutdowns and disruptions in travel to and from these busy airports. The study examined the effects of the 1%-annual-chance coastal flooding event for present day existing conditions and six different sea level rise scenarios at each airport. Storm surge model outputs from the Federal Emergency Management Agency (FEMA) provided the present day storm surge conditions. 50th and 90thpercentile sea level rise projections from the New York Panel on Climate Change (NPCC) 2013 report were incorporated into storm surge results using linear superposition methods. These projections were evaluated for future years 2025, 2035, and 2055. In addition to the linear superposition approach for storm surge at airports where waves are a potential hazard, one dimensional wave modeling was performed to get the total water level results. Flood hazard and flood depth maps were created based on these results. In addition to assessing overall flooding at each airport, major at-risk infrastructure critical to the continued operation of the airport was identified and a detailed flood vulnerability assessment was performed. This assessment quantified flood impacts in terms of potential critical infrastructure inundation and developed mitigation alternatives to adapt to coastal flooding and future sea level changes. Results from this project are advancing the PANYNJ

  18. Allowable residual-contamination levels for decommissioning facilities in the 100 areas of the Hanford Site

    International Nuclear Information System (INIS)

    This report contains the results of a study sponsored by UNC Nuclear Industries to determine Allowable Residual Contamination Levels (ARCL) for five generic categories of facilities in the 100 Areas of the Hanford Site. The purpose of this study is to provide ARCL data useful to UNC engineers in conducting safety and cost comparisons for decommissioning alternatives. The ARCL results are based on a scenario/exposure-pathway analysis and compliance with an annual dose limit for three specific modes of future use of the land and facilities. These modes of use are restricted, controlled, and unrestricted. The information on ARCL values for restricted and controlled use provided by this report is intended to permit a full consideration of decommissioning alternatives. ARCL results are presented both for surface contamination remaining in facilities (in dpm/100 cm2), and for unconfined surface and confined subsurface soil conditions (in pCi/g). Two confined soil conditions are considered: contamination at depths between 1 and 4 m, and contamination at depths greater than or equal to 5 m. A set of worksheets are presented in an appendix for modifying the ARCL values to accommodate changes in the radionuclide mixture or concentrations, to consider the impacts of radioactive decay, and to predict instrument responses. Finally, a comparison is made between the unrestricted release ARCL values for the 100 Area facilities and existing decommissioning and land disposal regulations. For surface contamination, the comparison shows good agreement. For soil contamination, the comparison shows good agreement if reasonable modification factors are applied to account for the differences in modeling soil contamination and licensed low-level waste

  19. Extended storage of low-level radioactive waste: potential problem areas

    International Nuclear Information System (INIS)

    If a state or state compact does not have adequate disposal capacity for low-level radioactive waste (LLRW) by 1986 as required by the Low-Level Waste Policy Act, then extended storage of certain LLRW may be necessary. The issue of extended storage of LLRW is addressed in order to determine for the Nuclear Regulatory Commission the areas of concern and the actions recommended to resolve these concerns. The focus is on the properties and behavior of the waste form and waste container. Storage alternatives are considered in order to characterize the likely storage environments for these wastes. The areas of concern about extended storage of LLRW are grouped into two categories: 1. Behavior of the waste form and/or container during storage, e.g., radiolytic gas generation, radiation-enhanced degradation of polymeric materials, and corrosion. 2. Effects of extended storage on the properties of the waste form and/or container that are important after storage (e.g., radiation-induced oxidative embrittlement of high-density polyethylene and the weakening of steel containers resulting from corrosion by the waste). The additional information and actions required to address these concerns are discussed and, in particular, it is concluded that further information is needed on the rates of corrosion of container material by Class A wastes and on the apparent dose-rate dependence of radiolytic processes in Class B and C waste packages. Modifications to the guidance for solidified wastes and high-integrity containers in NRC's Technical Position on Waste Form are recommended. 27 references

    Full Text Available Kajaran town is situated in the south-east of the Republic of Armenia in Syunik Marz. Developed mining and smelting industries can be observed in this area. This economic sphere is one of the main sources of soil pollution with heavy metals causing desertification of soils. Taking into consideration the location of the main sources of pollution six the most risky sites in this area and an unpolluted site as a control were selected for the study of pollution by heavy metals. The content of metals was determined by means of ELAN 9000 ICP-MS System. Study results revealed the increase up to 17 times in contents of following metals: Co, Ni, Cu, Zn, Cr, Sr, Mo, Cd, Pb, As. Based on Geoaccumulation index (Igeo classification, the soils from all sites may be classified between “practically uncontaminated” and “uncontaminated to moderate”. The pollution level for Cu (Igeo = 0.031-2.468 was higher than for other metals. The sites adjacent to Kajaran ore-dressing and processing enterprise are classified as “moderately to strongly” contaminated by Cu. Experiments have led us to the assumption that pollution of soils with heavy metals in the studied territory is conditioned by human activities, particularly by mining and smelting industry.

    Thirteen volatile organic compounds (VOCs) were quantified at three sites in southwestern Mexico City from July 2000 to February 2001. High concentrations of different VOCs were found at a Gasoline refueling station (GS), a Condominium area (CA), and at University Center for Atmospheric Sciences (CAS). The most abundant VOCs at CA and CAS were propane, n-butane, toluene, acetylene and pentane. In comparison, at GS the most abundant were toluene, pentane, propane, n-butane, and acetylene. Benzene, a known carcinogenic compound had average levels of 28, 35 and 250 ppbC at CAS, CA, and GS respectively. The main contributing sources of the measured VOCs at CA and CAS were the handling and management of LP (Liquid Propane) gas, vehicle exhaust, asphalt works, and use of solvents. At GS almost all of the VOCs came from vehicle exhaust and fuel evaporation, although components of LP gas were also present. Based on the overall results possible abatement strategies are discussed. - Volatile organic compounds were quantified in order to perform their source apportionment in southwestern area of Mexico City.

  2. SPECIAL ANALYSIS AIR PATHWAY MODELING OF E-AREA LOW-LEVEL WASTE FACILITY

    Energy Technology Data Exchange (ETDEWEB)

    Hiergesell, R.; Taylor, G.

    2011-08-30

    This Special Analysis (SA) was initiated to address a concern expressed by the Department of Energy's Low Level Waste Disposal Facility Federal Review Group (LFRG) Review Team during their review of the 2008 E-Area Performance Assessment (PA) (WSRC, 2008). Their concern was the potential for overlapping of atmospheric plumes, emanating from the soil surface above SRS LLW disposal facilities within the E-Area, to contribute to the dose received by a member of the public during the Institutional Control (IC) period. The implication of this concern was that the dose to the maximally-exposed individual (MEI) located at the SRS boundary might be underestimated during this time interval. To address this concern a re-analysis of the atmospheric pathway releases from E-Area was required. In the process of developing a new atmospheric release model (ARM) capable of addressing the LFRG plume overlap concern, it became obvious that new and better atmospheric pathway disposal limits should be developed for each of the E-Area disposal facilities using the new ARM. The scope of the SA was therefore expanded to include the generation of these new limits. The initial work conducted in this SA was to develop a new ARM using the GoldSim{reg_sign} program (GTG, 2009). The model simulates the subsurface vapor diffusion of volatile radionuclides as they release from E-Area disposal facility waste zones and migrate to the land surface. In the process of this work, many new features, including several new physical and chemical transport mechanisms, were incorporated into the model. One of the most important improvements was to incorporate a mechanism to partition volatile contaminants across the water-air interface within the partially saturated pore space of the engineered and natural materials through which vapor phase transport occurs. A second mechanism that was equally important was to incorporate a maximum concentration of 1.9E-07 Ci/m{sup 3} of {sup 14}CO{sub 2} in the air

    Radioactivity, natural and man-made, is omnipresent in the earth's crust in different amounts. Natural radioactive materials under certain conditions can reach hazardous radiological levels. So, it becomes necessary to study the natural radioactivity levels in soil to assess the dose for the population in order to know the health risks and to have a baseline for future changes in the environmental radioactivity due to human activities. 226Ra, 232Th and 40K analysis has been carried out in soil samples collected from some areas of Punjab, India using gamma-ray spectrometry. Phe technique of gamma ray spectrometry was applied using high purity germanium gamma-ray detector and a PC based MCA. Radium equivalent activities are calculated for the analyzed samples to assess radiation hazards arising due to the use of these soil samples in construction of dwellings. Phe measured activity in the soil ranges from 23.17 to 57.87 Bq kg-1, 59.03 to 160.40 Bq kg-1 and 228.06 to 501.03 Bq kg-1 for 226Ra, 232Ph and 40K with mean values of 37.93, 84.47 and 351.17Bqkg-1 respectively. It has been observed that on the average the outdoor terrestrial gamma air absorbed dose rate is about 84.65nGyh-1.

    Sediments are depositories of toxic substances such as organochlorine pesticides and there is a global need for their removal in contaminated environments. Studies that combine contaminated sediments and phytoremediation are relatively recent and their number has been increasing. This work aimed to investigate whether salt marsh plants (sea club-rush Scirpus maritimus, sea rush Juncus maritimus and sea purslane Halimione portulacoides) can favor DDT and metabolites remediation in estuarine environment. For this purpose the levels of DDT, DDE and DDD were compared in vegetated and non-vegetated sediments from an estuary in the North of Portugal ( in-situ study) and from another in the South of Portugal ( ex-situ study). Results obtained both in the in-situ study, involving S. maritimus and J. maritimus, and in the ex-situ study, involving H. portulacoides, indicated that these plants did not have a significant role in DDTs removal and/or degradation. Therefore, it seems that the tested plants cannot influence levels and distribution of DDTs in estuarine areas.

    The shallow groundwater in Shendong mining area was broken because of large-scale underground mining activities. Selecting 32201 working-face as research area,analyzed the change rule of groundwater level and aquifer thickness under mining impact with a large number of water level observation data. Then, the impacts of groundwater level change on vegetation were analyzed by the relationship theory of arid area groundwater and vegetation. The results show that the aquifer structure and the water condition of supply flow and drainage are changed by the water proof mining. The groundwater level recovere only a little compared with the original groundwater level in two years. But the great change of groundwater level do not have notable influences on vegetation of this mining area, and further study indicates that there are certain conditions where groundwater level change impacted on vegetation. When the influence of groundwater level change was evaluated, the plant ecological water level, warning water level and spatial distribution character of original groundwater and mining-impacted groundwater-level change should be integrated.

    Remote sensing technology has great potential for measuring lake inundation areas and lake levels, and providing important lake water quantity and quality information which can be used for improving our understanding of climate change impacts on the global water cycle, and assessing the influence of the projected future climate change on the global water resources. One remote sensing approach is to estimate lake level from satellite measured inundation area based on the inundation area—lake level rating (IALLR) curves. However, this approach is not easy to implement because of a lack of data for constructing the IALLR curves. In this study, an innovative and robust approach to construct the IALLR curves from the digital elevation model (DEM) data collected during the Shuttle Radar Topography Mission (SRTM) was developed and tested. It was shown that the IALLR curves derived from the SRTM DEM data could be used to retrieve lake level from satellite measured inundation area. Applying the constructed IALLR curve to the estimated inundation areas from 16 Landsat Thematic Mapper (TM) images, 16 lake levels of Lake Champlain in Vermont were obtained. The root mean square error (RMSE) of the estimated lake levels compared to the observed water levels at the U.S. Geological Survey (USGS) gauging station (04294500) at Burlington, Vermont is about 0.12 m.

    Full Text Available Background and Objectives: Genetics and environment have both been implicated in the exponential rise in the prevalence of diabetes mellitus that affects 65.1 million people, and leads to a mortality of 1 million people every year in India. This study was devised to obtain the trends of the distribution of blood glucose, and sociodemographic characteristics in rural areas of a North Indian state. Materials and Methods: A cross-sectional study was conducted at eight centers in five districts. A camp-based approach was followed in the diabetes screening conducted in rural areas. Blood glucose measurements were obtained after informed consent by trained staff using a reflectance photometer instrument. Descriptive statistics, distribution curves, log transformations, and tests for bimodality were obtained. Results: 45,318 participants consisting of 44.4% males and 55.6% females were screened. Ages ranged from 18 to 98 years with the mean age of 39.9 ± 14.44 years. 86.5% were normal (random blood sugar [RBS] 200 mg/dl. The median blood glucose level steadily rose with increasing age. The prediabetic to diabetic ratio was 4:1. The distribution curve of RBS was right skewed. A log transformation was applied, and bimodality was tested using the Hartigan′s dip test. The dip statistic (D was 0.0162 with a simulated P < 0.001. Conclusion: Mass screening for diabetes provides benefits from a clinical standpoint by helping to estimate the prevalence (diabetes and the hidden burden of the disease (prediabetes. Screening programs can strengthen healthcare system initiatives and reduce the growing burden of diabetes in India.

    Full Text Available A protocol that consisted of an isolation flux chamber and a portable gas chromatograph was used to directly quantify greenhouse gas (GHG emissions at a dairy and a feedyard operation in the Texas Panhandle. Field sampling campaigns were performed 5 consecutive days only during daylight hours from 9:00 am to 7:00 pm each day. The objective of this research was to quantify and compare GHG emission rates (ERs from ground level area sources (GLAS at dairy and cattle feedyard operations during the summer. A total of 74 air samples using flux chamber were collected from the barn (manure lane and bedding area, loafing pen, open lot, settling basin, lagoons, and compost pile within the dairy operation. For the cattle feedyard, a total of 87 air samples were collected from four corner pens of a large feedlot, runoff holding pond, and compost pile. Three primary GHGs (methane, carbon dioxide, and nitrous oxide were measured and quantified from both operations. The aggregate estimated ERs for CH4, CO2, and N2O were 836, 5573, 3.4 g hd−1 d−1 (collectively 27.5 kg carbon dioxide equivalent (CO2e hd−1 d−1, respectively, at the dairy operation. The aggregate ERs for CH4, CO2, and N2O were 3.8, 1399, 0.68 g hd−1 d−1 (1.7 kg CO2e hd−1 d−1, respectively, from the feedyard. The estimated USEPA GHG ERs were about 13.2 and 1.16 kg CO2e hd−1 d−1, respectively, for dairy and feedyard operations. Aggregate CH4, CO2 and N2O ERs at the dairy facility were about 219, 4 and 5 times higher, respectively, than those at the feedyard. At the dairy, average CH4 ERs estimated from the settling basin, primary and secondary lagoons were significantly higher than those from the other GLAS, contributing about 98% of the aggregate CH4 emission. The runoff holding pond and pen surface of the feedyard contributed about 99% of the aggregate CH4 emission. Average CO2 and N2O ERs estimated from the pen surface area were significantly higher than those estimated from

    Full Text Available Abstract Background There is a growing literature documenting socioeconomic inequalities in obesity risk among adults in the UK, with poorer groups suffering higher risk. Methods In this systematic review, we summarize and appraise the extant peer-reviewed literature about socioeconomic inequalities in adult obesity risk in the UK published between 1980 and 2010. Only studies featuring empirical assessments of relations between socioeconomic indicators and measures of obesity among adults in the UK were included. Results A total of 35 articles met inclusion criteria, and were reviewed here. Conclusion Socioeconomic indicators of low socioeconomic position (SEP, including occupational social class of the head-of-household at birth and during childhood, earlier adulthood occupational social class, contemporaneous occupational social class, educational attainment, and area-level deprivation were generally inversely associated with adult obesity risk in the UK. Measures of SEP were more predictive of obesity among women than among men. We outline important methodological limitations to the literature and recommend avenues for future research.

    Full Text Available This research study is based on primary data collection from sunflower growers to assess the socioeconomic factors that are affecting the adoption of sunflower varieties in Sindh.Data samples have been selected from two districts; Badin and Thatta, as these districts are considered main sunflower growing areas in Sindh. The results reveal that Sunflower growers are using Hybrid varieties i.e. 43 percent planted Hysun-33, 29 percent Hysun-38 and 28 percent Hysun-37 varieties. The finding of research using multinomial logistic regression suggests that farm size and level of education significantly affected the adoption of sunflower varieties. These factors are statistically significant at p<0.05. Theother variables such as tenancy status and source of income are not statistically significant in the adoption of sunflower varieties in Sindh.

    The properties of parallel-palte gridded ionization chambers with areas of 300 cm 2, developed by us for alpha spectrometry of samples with low specific alpha activity are reported. Several practical hints for optimum operating conditions are presented. The chambers can be operated routinely at atmospheric pressure for several days, without the need for purification of the gas filling (P10). The minimum detectable activity at 5 MeV is 0.01 pCi, based on 4.65 standard deviations of background and 1000 min counting time. At the GSF Research Center ionization chambers of this type are used for the analysis of natural alpha emitters, as well as of transuranium nuclides in environmental samples by: (a) direct alpha spectrometry without any previous treatment of the sample, (b) semi-direct spectrometry after removal of organic matter by low-temperature ashing and (c) spectrometry after chemical separation. Some typical examples of application are given. Furthermore the range of application of the chambers in comparison to semiconductor detectors in the field of low-level alpha spectrometry is discussed.

  2. Dose area product measurement for diagnostic reference levels and analysis of patient dose in dental radiography

    International Nuclear Information System (INIS)

    In this study, diagnostic reference levels (DRLs) were suggested and patient doses were analysed through the dose-area product value in dental radiography. In intraoral radiography, at three sites, i.e. molar, premolar and incisor on the maxilla and acquired third quartile values: 55.5, 46 and 36.5 mGy cm2, respectively, were measured. In panoramic, cephalo-metric and cone beam computed tomography, the values were 120.3, 146 and 3203 mGy cm2 (16 x 18 cm), respectively. It has been shown that, in intraoral radiography, the patient dose changes proportionally to the value of mA s, but the change in extra-oral radiography in response to mA s could not be confirmed. The authors could confirm, however, the difference in dose according to the manufacturer in all dental radiography examinations, except for panoramic radiography. Depending on the size of hospital, there were some differences in patient dose in intraoral radiography, but no difference in patient dose in extra-oral radiography. (authors)

  3. Infiltration control for low-level radioactive solid waste disposal areas: an assessment

    International Nuclear Information System (INIS)

    The primary mode of radionuclide transport from shallow land-disposal sites for low-level wastes can be traced to infiltration of precipitation. This report examines the factors that affect surface water entry and movement in the ground and assesses available infiltration-control technology for solid-waste-disposal sites in the humid eastern portion of the United States. A survey of the literature suggests that a variety of flexible and rigid liner systems are available as barriers for the stored waste and would be effective in preventing water infiltration. Installation of near-surface seals of bentonite clay admixed with dispersive chemicals seem to offer the required durability and low permeability at a reasonable cost. The infiltration rate in a bentonite-sealed area may be further retarded by the application of dispersive chemicals that can be easily admixed with the surface soil. Because the effectiveness of a dispersive chemical for infiltration reduction is influenced by the physico-chemical properties of the soil, appropriate laboratory tests should be conducted prior to field application

    The paper develops empirical Bayes and benchmarked empirical Bayes estimators of positive small area means under multiplicative models. A simple example will be estimation of per capita income for small areas. It is now well-understood that small area estimation needs explicit, or at least implicit use of models. One potential difficulty with model-based estimators is that the overall estimator for a larger geographical area based on (weighted) sum of the model-based estimators is not necessa...

    Full Text Available Reducing population physical inactivity has been declared a global public health priority. We report a detailed multi-level analysis of small area indices and individual factors as correlates of physical activity in deprived urban areas. Multi-level regression analysis was used to investigate environmental and individual correlates of physical activity. Nine individual factors were retained in the overall model, two related to individual intentions or beliefs, three to access to shops, work or fast food outlets and two to weather; age and gender being the other two. Four area level indices related to: traffic, road casualties, criminal damage and access to green space were important in explaining variation in physical activity.

Utilizing SeVI and InVI, the highly vulnerable districts are demonstrated that are likely to face significant challenges in coping with tropical cyclone and require strategies to address the various aspects of socio-economic and infrastructural vulnerability. Moreover, this model can be incorporated not only for multi-level governance but also to integrate it with the real-time weather forecasts to identify the predictive areas of vulnerability.

    The objective of this study was to examine the temporal trends of the association between area-level poverty status and end-stage renal disease (ESRD) incidence. We hypothesized that the association between area-level poverty status and ESRD incidence has increased significantly over time. Patient data from the United States Renal Data System were linked with data from the 2000 and 2010 US census. Area-level poverty was defined as living in a zip code-defined area with ≥20% of households living below the federal poverty line. Negative binomial regression models were created to examine the association between area-level poverty status and ESRD incidence by time period in the US adult population while simultaneously adjusting for the distribution of age, sex, and race/ethnicity within a zip code. Time was categorized as January 1, 1995 through December 31, 2004 (Period 1) and January 1, 2005 through December 31, 2010 (Period 2). The percentage of adults initiating dialysis with area-level poverty increased from 27.4% during Period 1 to 34.0% in Period 2. After accounting for the distribution of age, sex, and race/ethnicity within a zip code, area-level poverty status was associated with a 1.24 (95% confidence interval [CI] 1.22, 1.25)-fold higher ESRD incidence. However, this association differed by time period with 1.04-fold (95% CI 1.02, 1.05) higher ESRD incidence associated with poverty status for Period 2 compared with the association between ESRD and poverty status in Period 1. Area-level poverty and its association with ESRD incidence is not static over time. PMID:26094617

  12. Impact of fertilizers on background radioactivity level in two newly developed desert areas

    Science.gov (United States)

    Ahmad, Fawzia

    A survey of soils and plants was carried out to determine the environmental gamma background radiation levels in two newly developed desert areas. The materials and the standards were analyzed by gamma spectroscopy; a shielded high purity germanium detector was used to measure the natural concentration of 238U, 232Th and 40K activities in the samples. The radionuclide content in some commercial fertilizers was determined. The results of the analysis of specific activities in the fertilizers under study were 1.27-950.09 Bq/kg for 238U, 0.73-162.16 Bq/kg for 232Th and 10.22-23845.24 Bq/kg for 40K. All natural soil samples showed low-activity concen-trations. The concentrations of 238U (6.13-38.84 Bq/kg) and 232Th (2.58-25.69 Bq/kg) are quite similar, whereas that of 40K (113.91-9314.11 Bq/kg) are much higher for plant samples. Some of the results obtained are larger than the permissible international radioactivity levels. It is suitable in this regard to compare the activity values of the imported fertilizers and that fabricated in Egypt. The absorbed dose rate was found to be 1.91-1027 nGy/h and the radium equivalent activity concentration was 4.02-1840.98 Bq/kg for fertilizer samples. Soil and plant sample results were 11.86-415E29 nGy/h and 24.20-750.52 Bq/kg for the absorbed dose rate and the radium equivalent activity concentration, respectively. Banana plant contains the largest values. This article presents actual data from investigations of the soil-plant transfer of the primordial radionuclides for some fruits growing on these soils. The transfer factors of 0.35-1.821 for 238U, 0.227-0.480 for 232Th and 1.95-31.85 for 40K were obtained. The increase of the transfer of 40K reflects its great uptake to the fruits. Observed soil-plant factors vary widely, mainly as a result of different soil, vegetation types and environmental conditions. Taking into account the transfer factors of 137Cs to plants, the measured activity concentrations of this isotope should not

  14. Energy requirements and physical activity level of active elderly people in rural areas of Cuba

    International Nuclear Information System (INIS)

    Obesity and NIDDM are common in the Third Age and increasing in Cuba. Among the life-style changes associated with increased prevalence of obesity and its related disorders, diet and activity patterns are prime candidates. The transition to this life-style model may induce a decrease in the energy needs. There is an urgent need for tools which have been validated for measuring diet and physical activity in nutritional studies in the developing world, but also a more urgent need for reference values for the total energy requirements of healthy elderly people. Regular physical activity reduces the likelihood to develop diseases that characterise the metabolic cardiovascular syndrome. With the purpose of estimating the energy requirements, a group of 48 elderly people aged 61-74 years living in a rural mountain community was submitted to a medical, epidemiological, dietary and biochemical study of the nutritional status. Glucose intolerance was diagnosed in 40% and arterial hypertension was present in 23 % of them. Ten subjects without signs or symptoms of the metabolic cardiovascular syndrome were submitted to a measurement of the total energy expenditure by the doubly labelled water method. PAL values of 2.13 and 1.77 were measured for men and women, values which were significantly higher that the recommended value of 1.51 for elderly subjects. The total energy expenditure: The estimation of energy requirements by the energy intake or by the factorial method using the physical activity questionnaires generated values, which were 11 % and 30% lower than the values obtained by the DLW-method.

    Full Text Available Afforestation and reforestation activities in Sicily have been widespreaded in the last century. The results of forestation activities indicate the need to adopt a operational tools to promote the extension of forest surface at regional and sub-regional levels. In this view, with the aim to produce useful tools for forest plantation planning, the entire regional area was analysed and ecologically homogeneous areas have been identified to join and target arboriculture and/or forestation plantation activities, to choose tree and shrub species for different environments and to identify priority areas of intervention. The map of Rivas-Martinez bioclimate and the map of litological types were used as basic information layers to map pedo-climatic homogeneous areas. In order to mitigate disruptive hydrogeological effects and to reduce desertification risk and forest fragmentation, the Corine Land Cover map (CLC2000, the hydrogeological bond map and the desertification risk map were used to identify areas characterized by urgent need of forest activities at high priority level. A total of 23 ecologically homogeneous areas have been identified in Sicily, while more than a quarter of the regional surface has been characterized as highest priority intervention level. At sub-regional level, the target of the analysis was carried out at administrative province and at hydrographic basin level.

    Increasing fluoride levels in drinking water of fluorinated areas of world leading to fluorosis. For bio-monitoring of fluorosis patients, fluoride levels were determined in drinking water and human urine samples of different individuals having dental fluorosis and bony deformities from fluorotic area of Punjab (Sham Ki Bhatiyan, Pakistan) and then compared with reference samples of non fluorotic area (Queens Road, Lahore, Pakistan) using ion selective electrode methodology. Fluoride levels in fluorinated area differ significantly from control group (p < 0.05). In drinking water and human urine samples, fluoride levels in fluorinated areas were: 136.192 +- 67.836 and 94.484 +- 36.572 micro molL/sup -1/ respectively, whereas in control samples, fluoride concentrations were: 19.306 +- 2.109 and 47.154 +- 22.685 micro molL/sup -1/ in water and urine samples correspondingly. Pearson's correlation data pointed out the fact that that human urine and water fluoride concentrations have a significant positive dose response relationship with the prevalence of dental and skeletal fluorosis in fluorotic areas having higher fluoride levels in drinking water.

    Clonan, Angie; Roberts, Katharine E; Holdsworth, Michelle

    2016-08-01

    Red and processed meat (RPM) intake varies widely globally. In some high-income countries (HIC) the last decade has witnessed an overall decline or stabilisation in the consumption of RPM, in contrast to emerging economies where its consumption continues to increase with rising income and rapid urbanisation. The production and consumption of RPM have become major concerns regarding the environmental impacts of livestock in particular, but also because of associations between high RPM consumption and diet-related non-communicable disease. Therefore, it is important to identify socioeconomic and demographic drivers of the consumption of RPM. This paper explores how consumption of RPM differs with age, gender, socioeconomic status and in different global contexts. There are some key socioeconomic and demographic patterns in RPM consumption. Men tend to consume RPM more often and in higher quantities, and there is evidence of a social gradient in HIC, with lower socioeconomic groups consuming RPM more often and in larger quantities. Patterns for consumption with age are less clear cut. It is apparent that consumers in HIC are still consuming high levels of RPM, although the downward shifts in some socioeconomic and demographic groups is encouraging and suggests that strategies could be developed to engage those consumers identified as high RPM consumers. In low- and middle-income countries, RPM consumption is rising, especially in China and Brazil, and in urban areas. Ways of encouraging populations to maintain their traditional healthy eating patterns need to be found in low- and middle-income countries, which will have health, environmental and economic co-benefits.

    2010-01-01

    Full Text Available Abstract Background Young car drivers run a higher risk of road traffic crash and injury not only because of their lack of experience but also because of their young age and their greater propensity for adopting unsafe driving practices. Also, low family socioeconomic position increases the risk of crash and of severe crash in particular. Whether this holds true for young unlicensed drivers as well is not known. Increasing attention is being drawn to the prevalence and practice of unlicensed driving among young people as an important contributor to road traffic fatalities. Methods This is a population-based cohort study linking Swedish national register data for a cohort of 1 616 621 individuals born between 1977 and 1991. Crash circumstances for first-time road traffic crash (RTC were compared considering licensed and unlicensed drivers. The socioeconomic distribution of injury was assessed considering household socioeconomic position, social welfare benefits, and level of urbanicity of the living area. The main outcome measure is relative risk of RTC. Results RTCs involving unlicensed drivers were over-represented among male drivers, suspected impaired drivers, severe injuries, crashes occurring in higher speed limit areas, and in fair road conditions. Unlicensed drivers from families in a lower socioeconomic position showed increased relative risks for RTC in the range of 1.75 to 3.25. Those living in rural areas had an increased relative risk for a severe RTC of 3.29 (95% CI 2.47 - 4.39 compared to those living in metropolitan areas. Conclusions At the time of the crash, young unlicensed drivers display more risky driving practices than their licensed counterparts. Just as licensed drivers, unlicensed young people from low socioeconomic positions are over-represented in the most severe injury crashes. Whether the mechanisms lying behind those similarities compare between these groups remains to be determined.

    Full Text Available Abstract Background The proportion of older people is increasing rapidly in Vietnam. The majority of the elderly live in rural areas. Their health status is generally improving but this is less pronounced among the most vulnerable groups. The movement of young people for employment and the impact of other socioeconomic changes leave more elderly on their own and with less family support. This study aims to assess the daily care needs and their socioeconomic determinants among older people in a rural setting. Methods In 2007, people aged 60 years and older, living in 2,240 households, were randomly selected from the FilaBavi Demographic Surveillance System (DSS. They were interviewed using structured questionnaires to assess needed support in activities of daily living (ADLs. Individuals were interviewed about the presence of chronic illnesses that had been diagnosed by a physician. Participant socioeconomic characteristics were extracted from the FilaBavi repeat census. The repeat census used a repeat of the same survey methods and questions as the original FilaBavi DSS. Distributions of study participants by socioeconomic group, supports needed, levels of support received, types of caregivers, and the ADL index were described. Multivariate analyses were performed to identify socioeconomic determinants of the ADL index. Results The majority of older people do not need of support for each specific ADL item. Dependence in instrumental or intellectual ADLs was more common than for basic ADLs. People who need total help were less common than those who need some help in most ADLs. Over three-fifths of those who need help receive enough support in all ADL dimensions. Children and grandchildren are the main caregivers. Age group, sex, educational level, marital status, household membership, working status, household size, living arrangement, residential area, household wealth, poverty status, and chronic illnesses were determinants of daily care needs

    Full Text Available Objective: To analyze the sleep characteristics in adolescents from different socioeconomic levels. Data source: Original studies found in the MEDLINE/PubMed and SciELO databases without language and period restrictions that analyzed associations between sleep variables and socioeconomic indicators. The initial search resulted in 99 articles. After reading the titles and abstracts and following inclusion and exclusion criteria, 12 articles with outcomes that included associations between sleep variables (disorders, duration, quality and socioeconomic status (ethnicity, family income, and social status were analyzed. Data synthesis: The studies associating sleep with socioeconomic variables are recent, published mainly after the year 2000. Half of the selected studies were performed with young Americans, and only one with Brazilian adolescents. Regarding ethnic differences, the studies do not have uniform conclusions. The main associations found were between sleep variables and family income or parental educational level, showing a trend among poor, low social status adolescents to manifest low duration, poor quality of sleeping patterns. Conclusions: The study found an association between socioeconomic indicators and quality of sleep in adolescents. Low socioeconomic status reflects a worse subjective perception of sleep quality, shorter duration, and greater daytime sleepiness. Considering the influence of sleep on physical and cognitive development and on the learning capacity of young individuals, the literature on the subject is scarce. There is a need for further research on sleep in different realities of the Brazilian population.

    In light of growing coastal populations and rising relative sea levels, understanding the consequences of infrequent, high-impact coastal hazards for human migration is a key ingredient for meeting the challenges of sustainable development. Using new quantitative and qualitative evidence from 1160 households and 121 village leaders, we examine longer-term migration in the city of Banda Aceh, Indonesia, following the devastating 2004 tsunami and an international aid response that offered most survivors only resettlement back in the tsunami-affected area. While many survivors wanted to return, some preferred to relocate further from the coast but did not have the chance to do so. Since that time, selective out-migration by those with the means and socioeconomic sorting of newcomers have led to a new socioeconomic segregation of the tsunami-affected parts of the city. More broadly, these findings suggest that short-distance socioeconomic sorting into and out from vulnerable areas may be an important migratory response to a newly recognized risk.

    Abstract:
    Background: Injuries are the major cause of death and disability in European children. This study explored socioeconomic and gender structures in association with nonfatal childhood injury rates by sex and age groups in Sweden. Methods: Six indicators of socioeconomic structure and three indicators of gender structure were combined using principal component analysis. Sex- and age-specific mean annual injury rates of fourteen Swedish municipalities were estimated (2000–2005. The associations were analysed with Pearson’s correlation coefficients. Results: Narrow gender ratio in unskilled occupations and in politics was positively associated with injuries in girls 6–17 years (r ≥ 0.7 and with fractures in boys 6–12 years of age (r = 0.5. Wider income distribution was negatively associated (r ≥ -0.4 with boys’ injuries and positively associated with fractures in girls 13–17 years (r = 0.5. Relative wealth and male manager dominance was negatively associated with injuries in children 0–5 years (r = -0.4. Relative poverty was not associated with nonfatal childhood injuries. Conclusions: The strength of the associations between socioeconomic and gender structures and nonfatal childhood injury rates varied by sex, age group and type of injury. Childhood injury preventive interventions should consider the local gender structure, area-level wealth and area-level income distribution, and not only area-level poverty.

    Coal gangue is the most used filling material during reclamation of areas suffering subsidence from mining.Main trace element levels (F,As,Hg,and Pb) in shallow groundwater in the reclamation area may be affected by leaching from the gangue.This can has an impact on the application of the water for agricultural irrigation or use as drinking water.Therefore,it is of great significance to understand the effect coal gangue has on the shallow groundwater of a reclaimed area.We studied the effect of coal gangue on fluorine,arsenic,mercury,and lead levels in the shallow groundwater of a reclamation area by testing the water and the coal gangue.One well near the reclamation area was used as a control well and element levels in water from this well and from the soil next to the well were also measured.The results show that the levels of these elements are increasing in the reclamation area over time.The increase in fluorine,arsenic,mercury,and lead in monitor wells varies from 7.42% to 8.26%,from 7.13% to 7.90%,from 4.85% to 6.48%,and from 4.69% to 6.42%,respectively.Fluorine and arsenic levels are lower in monitor wells than in the control water.The other elements are found in greater concentration than in the control.The Nemerow index also indicates that the shallow groundwater in the reclamation area Ⅰ is moderately affected by the back-filling coal gangue,while the shallow groundwater in the reclamation area Ⅱ and Ⅲ are slightly affected by the back-filling coal gangue.This shallow groundwater could be used for agricultural irrigation or for drinking.

  17. Validation on groundwater flow model including sea level change. Modeling on groundwater flow in coastal granite area

    International Nuclear Information System (INIS)

    It is important to verify the groundwater flow model that reproduces pressure head, water chemistry, and groundwater age. However, water chemistry and groundwater age are considered to be influenced by historical events. In this study, sea level change during glacial-interglacial cycle was taken into account for simulating salinity and groundwater age at coastal granite area. As a result of simulation, salinity movement could not catch up with sea level changes, and mixing zone was formed below the fresh-water zone. This mixing zone was observed in the field measurement, and the observed salinities were agreed with simulated results including sea level change. The simulated residence time including sea level change is one-tenth of steady state. The reason is that the saline water was washed out during regression and modern sea-water was infiltrated during transgression. As mentioned before, considering sea level change are important to reproduce salinity and helium age at coastal area. (author)

    Full Text Available Abstract Background The major aim of this study was to investigate whether maternal risk factors associated with socioeconomic status and small for gestational age (SGA might be viable targets of interventions to reduce differential risk of SGA by socioeconomic status (socioeconomic SGA inequality in the metropolitan area of Vancouver, Canada. Methods This study included 59,039 live, singleton births in the Vancouver Census Metropolitan Area (Vancouver from January 1, 2006 to September 17, 2009. To identify an indicator of socioeconomic SGA inequality, we used hierarchical logistic regression to model SGA by area-level variables from the Canadian census. We then modelled SGA by area-level average income plus established maternal risk factors for SGA and calculated population attributable SGA risk percentages (PAR% for each variable. Associations of maternal risk factors for SGA with average income were investigated to identify those that might contribute to SGA inequality. Finally, we estimated crude reductions in the percentage and absolute differences in SGA risks between highest and lowest average income quintiles that would result if interventions on maternal risk factors successfully equalized them across income levels or eliminated them altogether. Results Average income produced the most linear and statistically significant indicator of socioeconomic SGA inequality with 8.9% prevalence of SGA in the lowest income quintile compared to 5.6% in the highest. The adjusted PAR% of SGA for variables were: bottom four quintiles of height (51%, first birth (32%, bottom four quintiles of average income (14%, oligohydramnios (7%, underweight or hypertension, (6% each, smoking (3% and placental disorder (1%. Shorter height, underweight and smoking during pregnancy had higher prevalence in lower income groups.

    People from lower socioeconomic status are making increasing use of mental health facilities. Surveys have indicated that the Rorschach is still one of the more frequently used instruments by psychologists in such facilities, but research has also shown that clinicians tend to misinterpret Rorschachs of people from the lower socioeconomic group as reflecting greater psychopathology than the same Rorschachs identified as being given by people from the middle class. Research has also shown that growing up in conditions of poverty significantly affects how people perform on tests of abstract thinking, tests of intelligence, and tests of academic achievement; the question was raised as to whether this extends to the Rorschach. The lack of sufficient research on the effect of socioeconomic status on responsiveness to the Rorschach precluded that question being answered. The kind of research still needed was discussed.

    Lead (Pb) has been proved to exert immunotoxicity to influence immune homeostasis in humans. To monitor the internal Pb level and evaluate its effect on natural killer (NK) cells and cytokine/chemokine concentrations, we recruited 285 preschool children from Guiyu, one of the largest electronic waste (e-waste) destinations and recycling areas in the world, and known to have high concentrations of Pb in the air, soil, water, sediment and plants. A total of 126 preschool children were selected from Haojiang as a reference group. Results showed that children in Guiyu, the exposed area, had higher blood Pb levels and lower percentages of NK cells than children from the reference area. A significantly negative association was found between the percentage of NK cells and increasing Pb levels. Moreover, children in Guiyu area had higher platelet counts and IL-1β concentrations, and lower levels of IL-2, IL-27, MIP-1α and MIP-1β were observed in the exposed children. These changes might not be conducive to the development and differentiation of NK cells. Taken together, the elevated Pb levels result in the lower percentages of NK cells, but also alter the levels of platelets, IL-1β and IL-27, which might be unconducive to the activity and function of NK cells.

    Strong socioeconomic inequalities exist in cardiovascular mortality and morbidity. The current review aims to synthesize the current evidence on the association between socioeconomic status (SES) and access to treatment of coronary heart disease (CHD). We examined quantitative studies analyzing the relationship between SES and access to CHD treatment that were published between 1996 and 2015. Our data sources included Medline and Web of Science. Our search yielded a total of 2066 records, 57 of which met our inclusion criteria. Low SES was found to be associated with low access to coronary procedures and secondary prevention. Access to coronary procedures, especially coronary angiography, was mainly related to SES to the disadvantage of patients with low SES. However, access to drug treatment and cardiac rehabilitation was only associated with SES in about half of the studies. The association between SES and access to treatment for CHD was stronger when SES was measured based on individual-level compared to area level, and stronger for individuals living in countries without universal health coverage. Socioeconomic inequalities exist in access to CHD treatment, and universal health coverage shows only a minor effect on this relationship. Inequalities diminish along the treatment pathway for CHD from diagnostic procedures to secondary prevention. We therefore conclude that CHD might be underdiagnosed in patients with low SES. Our results indicate that there is an urgent need to improve access to CHD treatment, especially by increasing the supply of diagnostic angiographies, to reduce inequalities across different healthcare systems.

    To fit the complicated geographic conditions of the Three Gorges Reservoir area, a two-level multi-objective monitoring system was developed to monitor the atmosphere of the area. Statistical analysis of environmental monitoring data and the macro control principle were employed to configure the upper layer. The lower layer was designed by the application of the thumb rule to a local terrain and specific point sources of pollution therein. The optimized two-level system comprises an upper layer of 16 monitoring stations distributed at places of diverse geographical, ecological, economical and social characteristics, and a lower layer of 16 sub-machines at each monitoring station of the upper layer. This optimal outcome fits the complicated conditions of the Three Gorges Reservoir area, substantially cuts down the installation cost and the operation cost, and provides accurate monitoring data of atmosphere over the entire area with a high resolution.

    The physicochemical properties of honey harvested from popular honey-producing areas in Tanzania were investigated. Honey from Shibe-Dodoma had the highest values of specific gravity, total acidity, free fatty acid content, diastatic number, overall acceptability, and lowest hydroxymethyl-furfural (HMF) level as compared to honey samples from other areas. There was no significant difference (p > 0.05) in terms of HMF in the other honey samples from Tanga, Morogoro, Same, Arusha, and Tabora. HMF levels in all honey samples were far below the maximum acceptable level of 40 mg/kg as recommended by the Codex Alimentarius Commission Standards before storage for 6 months. No traces of streptomycin and phenol were detected in all honey samples. It was concluded that according to the values of the studied quality parameters, the types of Tanzanian honey obtained from the popular honey producing areas may be judged to be of high quality.

    Soil samples were collected at 15 locations and unwashed overstory and understory vegetation samples were collected at nine locations within and around the perimeter of Area G, the primary disposal facility for low-level radioactive solid waste at Los Alamos National Laboratory (LANL). These samples were analyzed for {sup 3}H, {sup 238}Pu, {sup 239,240}Pu, {sup 90}Sr, {sup 241}Am, {sup 137}Cs, {sup 234}U, {sup 235}U, and {sup 238}U. Soil samples collected at Area G contained detectable concentrations of 3H (27%), {sup 239,240}Pu (60%), {sup 238}Pu (40%), and {sup 241}Am (47%) above regional statistical reference levels (RSRLs). In contrast, the levels of {sup 137}Cs, {sup 90}Sr, and U in all of the soil samples at Area G were either nondetectable or within RSRLs. The highest levels of {sup 3}H in soils were detected in the southwestern portion of Area G near the {sup 3}H shafts, whereas the highest concentrations of the Pu isotopes were detected in the northern and northeastern portions. All concentrations of {sup 3}H and Pu in soils, however, were far below LANL screening action levels. As for vegetation, most radionuclides in/on plants were either nondetectable or within RSRLs. The exceptions were {sup 3}H in overstory and some understory vegetation, particularly in the southwestern portion of Area G, which correlated very well with the soils data in that area. Also, there was some foliar contamination from {sup 241}Am and Pu isotopes in/on a few plant samples--the highest concentrations occurring in the northern section of Area G.

    Maximum permissible radiation levels for planned activities must be distinguished from action levels as applied to protect people and animals after nuclear accidents. The essential thing with action levels is the optimal balance between the danger of the radiation and the harm involved in the counter measures themselves. Among other things these counter measures are dependent on the magnitude of the fallout, i.e. on the apprehended doses to man and animals

    The objectives of this study were (1) to evaluate levels of lead (Pb) and cadmium (Cd) in the breast milk at 2 months postpartum, (2) to investigate the relationship between Pb and Cd levels in breast milk and some sociodemographic parameters and (3) to detect whether these levels have any influence on the infant's physical status or on postpartum depression in the mothers. Pb and Cd levels in breast milk were determined by Inductively Coupled Plasma Mass Spectroscopy (ICP-MS). The median breast milk concentrations of Pb and Cd were 20.59 and 0.67 {mu}g/l, respectively. In 125 (87%) of 144 samples, Pb levels were higher than the limit in breast milk reported by the World Health Organization (WHO) (> 5 {mu}g/l). Breast milk Cd levels were > 1 {mu}g/l in 52 (36%) mothers. The mothers with a history of anemia at any time had higher breast milk Pb levels than those without a history of anemia (21.1 versus 17.9 {mu}g/l; p = 0.0052). The median breast milk Cd levels in active and passive smokers during pregnancy were significantly higher than in non-smokers (0.89, 0.00 {mu}g/l, respectively; p = 0.023). The breast milk Cd levels of the mothers who did not use iron and vitamin supplements for 2 months postpartum were found to be higher than in those who did use the supplements (iron: 0.73, 0.00 {mu}g/l, p = 0.023; vitamin: 0.78, 0.00 {mu}g/l, p = 0.004, respectively). Breast milk Cd levels at the 2nd month were correlated negatively with the z scores of head circumference and the weight for age at birth (r = - 0.257, p = 0.041 and r = - 0.251, p = 0.026, respectively) in girls. We found no correlation between the breast milk Pb and Cd levels and the Edinburgh Postpartum Depression Scale scores. Breast milk monitoring programs should be conducted that have tested considerable numbers of women over time in view of the high levels of Pb in breast milk in this study. - Research highlights: {yields} Breast milk Pb levels were higher than the advised safety limits. {yields

Participaram do estudo 40 mães com filhos na faixa etária de 5 a 6 anos de ambos os sexos. Vinte mães eram de nível socioeconômico baixo e 20 mães eram de nível socioeconômico médio/alto de acordo com os critérios de Hollingshead. As mães responderam uma ficha de dados sociodemográficos e uma entrevista estruturada sobre práticas educativas maternas. Os resultados indicaram que as mães de nível socioeconômico baixo apresentaram maior frequência média de respostas na categoria punição física. Discutem-se as relações entre as variáveis sociodemográficas e as práticas coercitivas, destacando-se o efeito da escolaridade na maior variabilidade de repertório materno para a regulação do comportamento infantil.The present study compared coercive childrearing practices between mothers of different socioeconomic status. Participants in the study were 40 mothers of children of both sexes, aged 5 to 6 years. Twenty mothers were of low socioeconomic status, and twenty mothers were of medium/high socioeconomic status according to the criteria established by Hollingshead. The mothers were administered a sociodemographic data form and were interviewed about childrearing practices. The results indicated that the mothers of low socioeconomic status exhibited a greater average frequency of responses in the corporal punishment category. The relations between sociodemographic variables and coercive practices are discussed, emphasizing the effects of schooling on the greater variability in the maternal repertoire for regulating child behavior.

    A fundamental concept in visual processing is that activity in high-order object-category distinctive regions (e.g., lateral occipital complex, fusiform face area, middle temporal+) is dependent on bottom-up flow of activity in earlier retinotopic areas (V2, V3, V4) whose main input originates from primary visual cortex (V1). Thus, activity in down stream areas should reflect lower-level inputs. Here we qualify this notion reporting case LG, a rare case of developmental object agnosia and pro...

    Many of the core research questions of the "anthropocene" are spatial in nature, and require spatial data integration to provide the answers: Where are the people most vulnerable to environmental changes located? How do global environmental changes affect people, ecosystems or production systems in a given location? What are the impacts of human activities in the coastal zone, or mountainous areas, or drylands? This paper provides examples of the integration of remotely sensed biophysical and socioeconomic data that illustrate the benefits of spatial data integration. It also addresses some of the challenges in integrating data developed at different scales and for different purposes, sharing lessons learned from twenty years of operating the NASA Socioeconomic Data and Applications Center (SEDAC). Examples will be drawn from the literature on land use/land cover change, urbanization, disaster risk management, climate impact and vulnerability assessment, and natural resource management.

    API code is introduced at first, and then a comparison of seismic character and seismic hazard between Bohai and Southern California is carried out. The analysis indicates both the seismic frequency and intensity and the seismic hazard of Bohai are much weaker than that of Southern California. API code states the strength level and deformation level of permanent structures in Southern California takes 200 a and several hundred to a few thousand years respectively. But in the reference codes in China, the seismic levels take 500 a and 10 000 a for strength design and deformation design, and it seems too conservative. In China, the deformation level of class A structure takes 2%~3% probabilities of exceedance in reference period 100 a, and that of class B and C often takes 2%~3% in 50 a.Now that offshore platforms may cause server subsequent risk, it is safe to take 1% in 30 a as its deformation design level. On the basis of the above analyses and social economic level and the consistency with present codes,the strength design level and deformation design level of Chinese offshore platforms is suggested to take 200 a and 3 000 a respectively.

    The Yangtze River Delta region is characterized by high density of population and rapidly developing economy. There are low lying coastal plain and deltaic plain in this region. Thus, the study area could be highly vulnerable to accelerated sea level rise caused by global warming. This paper deals with the scenarios of the relative sea level rise in the early half period of the 21st century in the study area. The authors suggested that relative sea level would rise 25-50 cm by the year 2050 in the study area, of which the magnitude of relative sea level rise in the Yangtze River Delta would double the perspective worldwide average. The impacts of sea level rise include: (i) exacerbation of coastline recession in several sections and vertical erosion of tidal flat, and increase in length of eroding coastline; (ii) decrease in area of tidal flat and coastal wetland due to erosion and inundation; (iii) increase in frequency and intensity of storm surge, which would threaten the coastal protection works; (i

    Full Text Available Measurement of Radio Noise Level on 150Kc/s were carried out by a direct method at Delhi. The nature of diurnal variation of Mean Peak Noise level on this frequency was studied. The results were compared with those obtained for the same frequency in the American Sub-Arctic region, during 1947. The similarity in the nature of diurnal variation for these two places was observed. For both the places the peak noise level was found to be minimum in the early hours of the morning till sunrise, gradually increasing afterwards. From this observation, it was suggested that the ionosphere contributes most to the Radio Noise level around 150Kc/s. The observed value of peak noise level at Delhi was found to vary between 10uV/Metre/Kc Bandwidth and 0.35uV/Metre/Kc Bandwidth.

    Relevant geological, geographical, archaeological data were collected to study the characteristics of middle Holocene warm period and sea level high on North China coast. Middle Holocene climate and sea level change on North China coast were correlated to warm marine environment events in about 8-3 ka B.P. The sea level in about 8 ka B.P. was higher than present mean sea level, then fluctuated for 5 000 years and after that it became even in 3 ka B.P. The highest sea level occurred in about 6-5 ka B.P.; the maximum was about 2-3 m and minimum was about 1-2 m.

  20. Levels of thoron and progeny in high background radiation area of southeastern coast of Odisha (India))

    International Nuclear Information System (INIS)

    Exposure to radon, 222Rn, is assumed to be the most significant source of natural radiation to human beings in most cases. It is thought that radon and its progeny are major factors that cause cancer. The presence of thoron, 220Rn, was often neglected because it was considered that the quantity of thoron in the environment is less than that of radon. However, recent studies have shown that a high thoron concentration was found in some regions and the exposure to 220Rn and its progeny can equal or several time exceed that of 220Rn and its progeny. The results of thoron and its progeny measurements in the houses of high background radiation area (HBRA) of the southeastern coast of Odisha (India)) presented here. This area is one of the high background radiation areas in India with a large deposit of monazite sand which is the probable source of thoron. Both active and passive methods were employed for the measurement of thoron and its progeny in cement, brick and mud houses in the study area. Thoron concentration was measured using RAD-7 and Raduet. A CR-39 track detector was employed for the measurement of environmental thoron progeny, both in active and passive modes. Thoron and its progeny concentrations were found to be comparatively high in the area. A comparison between the results obtained with various techniques is presented in this paper. (authors)

    Recently we surveyed the thyroid function and TSH concentration of villagers in an endemic goiter area where iodized salt had been supplied for 25 years. We found that the serum FT3 and TSH (IRMA) level of villagers were higher and the FT4 level was lower than those of the controls, comparing with the RIA, which suggested that the inhabitants of the endemic goiter area had subclinical hypothyroidism based on the IRMA method for TSH assay. Therefore, we suggest that the best biochemical technique for monitoring the iodized salt prophylaxis program and the physiological response of villagers to iodine is measurement of serum TSH level with the ultrasensitive assay and FT4 level periodically.

    This report shows the altitudes of water levels in the Chicot and Evangeline aquifers in the Houston metropolitan area, Texas. Of the 425 wells measured, 307 were used to construct the maps of potentiometric surface. The Chicot and Evangeline aquifers are composed of several sand layers, each with a separate potentiometric surface. These maps, however, show a single potentiometric surface which represents the collective water levels for the sand layers comprising each aquifer. (USGS)

  6. Spatial Spread of Tuberculosis through Neighborhoods Segregated by Socioeconomic Position: A Stochastic Automata Model

    Full Text Available Transmission of the agent of tuberculosis, Mycobacterium tuberculosis, is dependent on social context. A discrete spatial model representing neighborhoods segregated by levels of crowding and immunocompetence is constructed and used to evaluate prevention strategies, based on a number of assumptions about the spatial dynamics of tuberculosis. A cellular automata model is used to (a construct neighborhoods of different densities, (b model stochastically local interactions among individuals, and (c model the spread of tuberculosis within and across neighborhoods over time. Since infected people may become progressively sick but also heal through treatment, the transition among stages was modeled with transition probabilities. A moderate level of successful treatment (40% dramatically reduced the number of infections across all neighborhoods. Increasing the treatment in neighborhoods of a lower socioeconomic level from 40% to 90% results in an additional decrease of approximately 25% in the number of infected individuals overall. In conclusion, we find that a combination of a moderate level of successful treatment across all areas with more focused treatment efforts in lower socioeconomic areas resulted in the least number of infections over time.

  7. Monitoring of the water levels in the wetlands of Fourmile Branch near the F- and H-areas of SRS

    International Nuclear Information System (INIS)

    The South Carolina Department of Health and Environmental Control (SCDHEC) has issued a Resource Conservation and Recovery Act (RCRA) Hazardous Waste Part B Permit that prescribes a remediation approach for the groundwater in the F- and H-Area (Sadler, 1995). This approach calls for the installation of extraction and injection wells to capture and remediate the 10,000 pCi/ml tritium contaminant plume. Modeling of the groundwater remediation system suggests that wetland areas near Fourmile Branch may be impacted by reduced water levels. In order to assess potential impacts of the remediation effort on the riparian wetland system, a network of piezometers has been established. This network of piezometers has been established along the groundwater outcrop (i.e. seepline) for the water table aquifer, specifically targeting those areas closest to the extraction wells. The purpose of the piezometer network is to establish baseline hydraulic head data for the water table aquifer at the F- and H-Area seeplines prior to startup of the groundwater extraction/injection remediation system. A total of twenty piezometers were installed at fourteen different locations. Twelve piezometers were installed in F-Area, and eight were installed in H-Area. Following installation, monthly water level measurements have been taken from each piezometer, and are presented in this report. Additionally, some piezometers have been instrumented with data loggers to allow for continuous monitoring of water levels. The purpose of continuous monitoring is to investigate the natural variability of water levels in the riparian wetland system of Fourmile Branch. Of particular interest is the variation in water levels associated with rainfall events, and evapotraspiration demand. The frequency, magnitude, and duration of these natural variations are unknown, and more frequent monitoring is required to assess them

    Full Text Available Leptospirosis is an epidemic-prone zoonotic disease that occurs worldwide, with more than 500,000 human cases reported annually. It is influenced by environmental and socioeconomic factors that affect the occurrence of outbreaks and the incidence of the disease. Critical areas and potential drivers for leptospirosis outbreaks have been identified in Nicaragua, where several conditions converge and create an appropriate scenario for the development of leptospirosis. The objectives of this study were to explore possible socioeconomic variables related to leptospirosis critical areas and to construct and validate a vulnerability index based on municipal socioeconomic indicators. Municipalities with lower socioeconomic status (greater unsatisfied basic needs for quality of the household and for sanitary services, and higher extreme poverty and illiteracy rates were identified with the highest leptospirosis rates. The municipalities with highest local vulnerability index should be the priority for intervention. A distinction between risk given by environmental factors and vulnerability to risk given by socioeconomic conditions was shown as important, which also applies to the “causes of outbreaks” and “causes of cases”.

    Full Text Available Abstract Background Malaria is one of the leading causes of mortality and morbidity in Nigeria. It is not known how user fees introduced under the Bamako Initiative (BI system affect healthcare seeking among different socio-economic groups in Nigeria for diagnosis and treatment of malaria. Reliable information is needed to initiate new policy thrusts to protect the poor from the adverse effect of user fees. Methods Structured questionnaires were used to collect information from 1594 female household primary care givers or household head on their socio-economic and demographic status and use of malaria diagnosis and treatment services. Principal components analysis was used to create a socio-economic status index which was decomposed into quartiles and chi-square for trends was used to calculate for any statistical difference. Results The study showed that self diagnosis was the commonest form of diagnosis by the respondents. This was followed by diagnosis through laboratory tests, community health workers, family members and traditional healers. The initial choice of care for malaria was a visit to the patent medicine dealers for most respondents. This was followed by visit to the government hospitals, the BI health centres, traditional medicine healers, private clinics, community health workers and does nothing at home. Furthermore, the private health facilities were the initial choice of treatment for the majority with a decline among those choosing them as a second source of care and an increase in the utilization of public health facilities as a second choice of care. Self diagnosis was practiced more by the poorer households while the least poor used the patent medicine dealers and community health workers less often for diagnosis of malaria. The least poor groups had a higher probability of seeking treatment at the BI health centres (creating equity problem in BI, hospitals, and private clinics and in using laboratory procedures.

We have carried out a differential study taking into account family SES and school SES in a multi-level study context. First, via tested hierarchical models, the hypothesis of the contextual effects (i.e., double jeopardy is accepted, showing that the academic achievement of students from low SES families tend to worsen when they attend low SES schools. In order to illustrate the different effect of both SES, a new variable is generated so that, for each student, it combines the values of the previously categorized family and school SES. Using statistical segmentation techniques (regression and classification trees, CART, the present study has found that low family SES students attending high SES schools obtain the best academic achievement results, only outperformed by high family SES students who are studying at high SES schools, and also, even better than the sample subgroups who were expected to get much better scores. The study ends with some explanatory hypotheses about the findings and with some suggestions for further research.

  2. Radioactivity levels in well water supplies within the greater Chicago area

    International Nuclear Information System (INIS)

    The radiological analysis of well water supplies within the geographical boundaries of the Metropolitan Sanitary District of Greater Chicago was prompted by the relatively high total alpha levels encountered in wastewaters of a MSDGC water reclamation plant as compared to the wastewaters of the other waste treatment plants. Consequently, 87 wells constituting 42 water supplies were sampled and analyzed for total alpha and beta radioactivity. The wells were grouped according to depth. In general, both total alpha and total beta radioactivity concentrations were found to be a function of well depth. The relatively higher total alpha and beta activities in the wastewaters to one of the treatment plants was attributed to the higher levels found in the well water supply. Comparison with the USEPA's Drinking Water Regulations for Radionuclides (July 9, 1976) showed the maximum total alpha level of 15 pCi/liter was exceeded in 3 wells and 32 of the deep well waters had total alpha level greater than 5 pCi/liter. The total beta level of 50 pCi/liter was exceeded in 8 wells

  3. Rising Seas: Threat to Coastal Areas, A General Study about the Sea Level Rises on Coastal Areas of Earth, its Consequences and Preventive Measures.

    2015-12-01

    Scientific research indicates that sea levels worldwide have been rising at a rate of 3 millimeters per year since the early 1990s (IPCC), which is much higher than the previous century. The recent measurements (march 2015; NASA) tells us that the present rise of sea level is 64.4 mm. Most recent satellite measurements and tide gauge readings (NASA) tell us that present rate sea level rise is 3.20 mm per year. A recent study says we can expect the oceans to rise between 2.5 and 6.5 feet (0.8 and 2 meters) by 2100. The two main causes of rising seas are thermal expansion and glacier melting which further corresponds to the root cause of sea level rise: Green House effect. For every degree Celsius that global average temperature rises, we can expect 2.3 meters of sea-level rise sometime over the ensuing 2,000 years. The main consequence of Sea level rise is increase in oceanic acidity as it releases the entrapped carbon dioxide in between the glaciers. The problem goes from bad to worse when we take into consideration that one third of the world population lives in a 60 km range from the coast. In the event of a flood, this massive population would have to move away from the coasts. The main objective of research is to find all the most vulnerable areas, to make people aware about the consequences and to take proper measurements to fight with such natural calamities. The rise in sea level would inevitably cause massive migration like never seen before. Over 25% of the world population could disappear if sea levels continues to rise with same or faster rate as present. The oceans, sea life and life of people at coastal areas will get extremely effected unless there are considerable cuts in the carbon dioxide emissions. What we need to do is just to apply all the methods and measurements in our daily life that can help reduce the green house gases emissions. Also we need to plan that how to prevent all these cities in case of such natural hazards.

  10. The changes of plasma adrenomedullin level in Han and tibetan health adult men in plateau area

    International Nuclear Information System (INIS)

    To investigate the changes and clinical significance of plasma adrenomedullin in Han and Tibetan health adult men at the state of chronic hypoxia. The Han health adult who migrated and lived above sea level 4200 meter for 1∼3 years and the native Tibetan were involved in this study. The plasma adrenomedullin levels in both Han and Tibetan health adult men were measured by RIA. The results showed that the plasma adrenomedullin levels of native Tibetan were significantly higher than that of migrated Han worker (P<0.05). The plasma adrenomedullin might play a regulatory role on the physiological function in the health adult men who live in high altitude hypoxic state. (authors)

    Objective. This study examined the hypothesis that correlations exist between the carbon monoxide exposure time and the carboxyhemoglobin concentration at the site of carbon monoxide poisoning, using a pulse carbon monoxide oximeter in rural areas or the carboxyhemoglobin concentration measured at a given medical institution. Background. In previous studies, no definitive relationships between the arterial blood carboxyhemoglobin level and the severity of carbon monoxide poisoning have been observed. Method. The subjects included patients treated for acute carbon monoxide poisoning in whom a medical emergency team was able to measure the carboxyhemoglobin level at the site of poisoning. We examined the relationship between the carboxyhemoglobin level at the site of poisoning and carbon monoxide exposure time and the relationships between the arterial blood carboxyhemoglobin level and carbon monoxide exposure time. Results. A total of 10 patients met the above criteria. The carboxyhemoglobin levels at the site of poisoning were significantly and positively correlated with the exposure time (rs = 0.710, p = 0.021), but the arterial blood carboxyhemoglobin levels were not correlated with the exposure time. Conclusion. In rural areas, the carboxyhemoglobin level measured at the site of carbon monoxide poisoning correlated with the exposure time. PMID:27239377

    Full Text Available Airborne Light Detection and Ranging (LiDAR generates high-density 3D point clouds to provide a comprehensive information from object surfaces. Combining this data with aerial/satellite imagery is quite promising for improving land cover classification. In this study, fusion of LiDAR data and aerial imagery based on Bayesian theory in a three-level fusion algorithm is presented. In the first level, pixel-level fusion, the proper descriptors for both LiDAR and image data are extracted. In the next level of fusion, feature-level, using extracted features the area are classified into six classes of “Buildings”, “Trees”, “Asphalt Roads”, “Concrete roads”, “Grass” and “Cars” using Naïve Bayes classification algorithm. This classification is performed in three different strategies: (1 using merely LiDAR data, (2 using merely image data, and (3 using all extracted features from LiDAR and image. The results of three classifiers are integrated in the last phase, decision level fusion, based on Naïve Bayes algorithm. To evaluate the proposed algorithm, a high resolution color orthophoto and LiDAR data over the urban areas of Zeebruges, Belgium were applied. Obtained results from the decision level fusion phase revealed an improvement in overall accuracy and kappa coefficient.

    Even though geothermal energy is a renewable energy source that is seen as cost-effective and environmentally friendly, emissions from geothermal plants can impact air, soil, and water in the vicinity of geothermal power plants. The Cerro Prieto geothermal complex is located 30 km southeast of the city of Mexicali in the Mexican state of Baja California. Its installed electricity generation capacity is 720 MW, being the largest geothermal complex in Mexico. The objective of this study was to evaluate whether the emissions generated by the geothermal complex have increased the soil mercury concentration in the surrounding areas. Fifty-four surface soil samples were collected from the perimeter up to an approximate distance of 7660 m from the complex. Additionally, four soil depth profiles were performed in the vicinity of the complex. Mercury concentration in 69 % of the samples was higher than the mercury concentration found at the baseline sites. The mercury concentration ranged from 0.01 to 0.26 mg/kg. Our results show that the activities of the geothermal complex have led to an accumulation of mercury in the soil of the surrounding area. More studies are needed to determine the risk to human health and the ecosystems in the study area. PMID:27418073

  15. Observation of underground water level in the area of forest estate "Sremska Mitrovica " during 2000 and 2001

    Full Text Available Observation of underground water level in the area of "Jasensko-Belilo", which belongs to the Forest Estate "Sremska Mitrovica", started in 1999. The measurements were performed by means of 2 piezometers set up approximately perpendicularly to the river Sava, forming profile number 1 (Fig.1. The results of these measurements (Fig. 2, 3 show a significant lowering of groundwater level in 2000. The reason is most likely the unfavorable rainfall amount and distribution during that year (Table 2. A much better situation was during 2001 when the minimal groundwater level was up to 2 meters and it was considered to be the result of a favorable amount of rainfall and its distribution during the year (Tables 2, 3. It was noticed that Carpinus betulus appears instead of flowering ash (Fraxinus ornus, which is a good sign that generally the level of underground water is lowering. Also, the phenomenon that pedunculate oak (Quercus robur gradually loses its natural regeneration capability also confirms the trend of lowering underground water level. If this trend continues, oak will be in a very near future naturally substituted by less valuable species, probably Turkey oak (Quercus cerris. If groundwater wells along the river Sava reach the vicinity of this area, which is a plan for the Belgrade city water supply, the trend of groundwater table lowering will be even more expressed and it will certainly endanger the existence of all valuable forest species in this area.
