    2017-01-01

    With a fast rise in large-scale wind power development in Sweden and other countries in recent years, issues related to energy justice generally and distributional justice specifically have become concerns in windmill siting. Some research, for instance, has indicated that it is easier to build windmills in economically marginalized communities. The evidence for this, however, is still limited. Thus, this study aims to statistically evaluate the extent to which the decisions to approve or reject windmill proposals in Sweden can be explained by factors related to the socio-economic characteristics of people living in the areas surrounding windmill sites. The study is based on an odds ratio analysis of decisions on all windmill proposals in Sweden, in which geo-referenced socio-economic data on an individual level for all inhabitants within 3 and 10 km of the windmill sites are studied. The results show skewness in the distribution of windmills, with a higher likelihood of rejection in areas with more highly educated people and people working in the private sector, compared to a higher likelihood of approval in areas with more unemployed people. This skewness, while not necessarily unjust, warrants further policy and research attention to distributional justice issues when developing wind power. - Highlights: • The distributional justice of windmill siting in Sweden is statistically evaluated. • Windmill siting decisions are related to people's socio-economic characteristics. • The results indicate some distributional skewness for wind power development. • The study gives statistical rigour and generalisability to energy justice findings. • The results warrant follow-ups and policy guides for how to handle benefit-sharing.

    To examine whether area level socioeconomic disadvantage and social capital have different relations with women's and men's self rated health. The study used data from 15 112 respondents to the 1998 Tasmanian (Australia) healthy communities study (60% response rate) nested within 41 statistical local areas. Gender stratified analyses were conducted of the associations between the index of relative socioeconomic disadvantage (IRSD) and social capital (neighbourhood integration, neighbourhood alienation, neighbourhood safety, political participation, social trust, trust in institutions) and individual level self rated health using multilevel logistic regression analysis before (age only) and after adjustment for individual level confounders (marital status, indigenous status, income, education, occupation, smoking). The study also tested for interactions between gender and area level variables. IRSD was associated with poor self rated health for women (age adjusted plevel variables. Political participation and neighbourhood safety were protective for women's self rated health but not for men's. Interactions between gender and political participation (p = 0.010) and neighbourhood safety (p = 0.023) were significant. These finding suggest that women may benefit more than men from higher levels of area social capital.

  5. Local economic impact of nuclear power

    International Nuclear Information System (INIS)

    Shurcliff, A.W.

    1977-01-01

    The local economic impact of nuclear installations is examined and the conclusion reached that much of the subsequent area growth may be coincidental to the facility. Nuclear siting criteria favor proximity to a regional power grid, abundant water for cooling, and extensive vacant land with a major access road. These criteria coincide with the characteristics of commuter suburbs, centers for retirement, and recreation areas. Clustering of nuclear units introduces an extraordinary level of new construction, office requirements, and capital. Economic changes will occur at the start and completion of the construction stage and at the time of decommissioning the facility. Past experiences are detailed in terms of employment, payroll, housing, public services, and procurement. When construction is completed, employment falls to a relatively low level. Proximity to the plant offers no advantage in terms of local power rates. While nuclear facilities do not preclude other development in the area, there are restrictions on access, regulatory agencies may reject absorbing the cost of public use as a business expense in the rate structure, and security measures may constrain public use. There is pressure for tax equalization laws to compensate communities for the loss of potential property tax revenues. Some agencies (e.g., the Tennessee Valley Authority) make in-lieu-of-tax payments, while some plants have produced tax benefits large enough to effect significant public improvements. 8 references

    Full Text Available In the present article we propose to analyze and deepen significant categories of costs funded from the local budgets, namely the expenditure for economic activities. Our scientific approach begins with determining the place occupied by such expenses in local public expenditure by specifying their content and role. The center of gravity of the study is to treat and deepen the three subgroups of expenses that we consider representative: "The expenses for production, transportation, distribution and supply of heat in a centralized system", "Transport Costs" and Expenditure for agriculture and forestry ". The reaserch is based on the quantitative analysis of the expenses for economic actions, in local budgets, based on the existing data from the Statistical Yearbook of Romania, and highlights the structure of this type of expenses as well as the place they hold in the expediture of local budgets.The study includes an analysis of the dynamics of the share held by economic costs within total expenses from local budgets. From the reaserch carried out, it is shown that the evolution and structure of the expenditures for economic actions from local budgets is determined by the action of certain economical and social factors that vary from one administrative teritorial unit to another: the ray of economical develpoment of the administrative ter itorial unit, urbanization, the number and social structure of the population. The reaserch shows that in the field of expenses for economic actions, the largest share is held by expenditures for transportation (almost 80%, far away from the expenses for fuel and energy (13,66%. During the 1999-2013 the dynamic of expenses for economical actions in the total of expenditures of local budgets, is sinusoidal due to the intervention of certain legislative changes.

  8. Local economic impacts associated with pure taxable capacity changes

    Bjornstad, D.J.

    1982-01-01

    A fiscal-impact model based on the introduction of a nuclear power plant demonstrates the need to integrate local public-sector impacts with local private-sector impacts when estimating the economic changes a community undergoes in response to a significant exogenous shock. A nuclear plant differs from other electrical generating facilities because siting regulations require locating in a low-population density area where the influence on the community will be substantial. These characteristics approximate the pure fiscal capacity change or pure tax revenue importation concept. Four sections of the paper describe local decision making on taxes, identify the parameters that may shape local impact, analyze indifference curves as they integrate with the local macroeconomic model, and compare data for two communities in which both private and public local economic sectors show stimulation. 12 references, 1 figure

  12. ECONOMIC GROWTH THEORIES, CONCEPTUAL ELEMENTS, CHARACTERISTICS

    Directory of Open Access Journals (Sweden)

    Florina, POPA

    2014-11-01

    Full Text Available The approach of economic growth involves understanding the concept and growth factors, respectively, analysing the growth theories, their trend in the context of the development of economic and social life. The economic growth signifies a process aimed at increasing activities in the national economy, expressed by macroeconomic indicators, respectively, the dynamics of the overall Gross Domestic Product or per inhabitant. It can appreciate that, in the short term, this process signifies phases of economic prosperity and on the long-term, expresses an upward trend, a consequence of the succession of increases and decreases. The study presents some elements which outlines the concept of economic growth, that is, definitions, meanings and the main characteristics of the theories of growth, as well as some of its determinant factors. Also, it gives a brief overview of the main theories of economic growth, as they have evolved over time, in line with the economic reality dynamics and the development of the instruments of economic analysis, starting from the classical theories to the new theories and models of economic growth of the modern age.

  13. A look at local economic impacts

    Bradfield, M.

    1998-01-01

    The benefits of mega-projects such as Hibernia and the Sable Offshore Energy Project on the local economies in Newfoundland and Nova Scotia were discussed. It was argued that most of the spin-off activities of such mega-projects are realized externally because the projects are driven by external interests and external funding, and are designed for external markets. Few of the short-term activities that can be done locally provide opportunities for sustained economic growth. Studies have shown that the impact of mega-projects on smaller economies is mainly on the construction sector and related supplies industries. Another reason why mega-projects have limited real effects on the local economy is that foreign investors have traditional supply sources, often with affiliated companies. Local availability of appropriate skills is yet another potential limiting factor. Moreover, most mega-projects have social, environmental and political consequences that are often under-estimated and ignored. In this author's view, most mega-projects have limited long-term domestic spin-offs. The challenge is to maximize the net benefits, and to minimize the social and environmental costs

    Full Text Available Base economic characteristics (total revenues, total costs, profit and profitability ratio of the Slovak Pinzgau breed were calculated in this study. Under the actual production and economic conditions of the breed, production system is operated with loss (-457 € per cow and per year and with negative profitability ratio (-20%. Optimisation of the production parameters on the level defined in the breed standard (5,200 kg milk per cow and year, 92% for conception rate of cows, 404 days of calving interval and 550 g in daily gain of reared heifers and improved udder health traits (clinical mastitis incidence and somatic cells score was of positive impact on the total revenues (+34%, on the effective utilisation of costs (+105% and balanced profit of dairy systems. Next to the positive profitability of the system, higher quality and security of dairy milk products should be mentioned there. Moreover, direct subsidies as an important factor of positive economic result of dairy cattle systems has to be pointed as well. Subsidies should be provided to compensate the real biological limitation of the local breed farmed in marginal areas. However, improvement of the production parameters of the Slovak Pinzgau breed is recommended with the same attention to reach the economic sustainability of dairy production system. To reach economic sustainability of the breed from practical point of view, the farmer activity should be aimed especially to the enhanced herd management.

    Objective: To assess the CT characteristics of thoracoabdominal localized Castleman disease (LCD) in 55 cases and correlate with histopathologic features. Methods: Fifty-five patients with LCD proved histopathologically in thorax (n=25) and abdomen (n=30) were collected during past 20 years. The unenhanced and contrast-enhanced CT were performed in all patients. Two radiologists reviewed CT images and the CT findings were analyzed simultaneously. Results: In 54 patients with hyaline-vascular type (n=50) and mixed type (n=4) localized CD, the lesion typically presented as solitary mass (90.7%, 49 cases), with irregular or lobular or infiltrative margin (83.3%, 45 cases), central calcification (38.9%, 21 cases), marked enhancement (100%, 54 cases), focal non-necrosis low attenuation areas (72.2%, 39 cases), lymphadenopathy (70.4%, 38 cases) and dilated feeding vessels adjacent to the mass (96.3%, 52 cases). One lesion with plasma cell type localized CD presented as a mass with irregular margin, mild enhancement and central necrosis, Four morphologic patterns were classified on CT, including solitary mass with well-circumscribed margin (n=4), irregular or lobular margin (n=30), infiltrative or halo-like margin (n=16), and multiple coalescent masses (n=5). Conclusion: CT features of thoracoabdominal localized CD are closely related to the location and pathological type. LCD with hyaline-vascular and mixed type has typical CT characteristics, while LCD with plasma cell type has no typical CT findings. (authors)

  20. Local Decentralisation and Economic Growth in Nigeria

    2014-06-01

    Full Text Available The current global drive towards devolution of financial resources and responsibilities has been increasingly justified on the basis that greater transfers of these financial resources and responsibilities to sub-central governments are theoretically expected to deliver greater economic efficiency in the provision of public goods and services and hence greater economic growth. There is a mixed result on these theoretical expectations across earlier empirical literatures. Using the instrumental variables (IV technique of analysis with the recent data from Nigeria for the period 1970-2013, this study found no robust significant effect of the decentralisation of spending or revenue on growth of real GDP per capital in Nigeria. The implication of this to the policy makers is that when it comes to the determinants of improved economic activities, decentralisation either fiscal expenditure or revenue side would not be instrumental to economic growth possibly because of existence of endemic corruption among politicians in Nigeria.

  3. Economic Efficiency of Selected Financial System Institutions of Local Government

    Full Text Available Functioning of local government units, as for as the economic sphere is concerned, is based on the financial law regulations. Those regulations aim at solving economic and social problems. The analysis of economic efficiency concerning implemented regulations is of particular importance for changing the EU’s attitude towards the influence, which EU has on functioning of the local governments. Implementing the local budgets, based on regulations which economic efficiency hasn’t been evaluated on the stage of legislation, may have a negative impact on local community and the economic situation of the country. Frequent changes of financial law cause actions, which financial effects cannot be predicted. What is more, those unstable regulations make it impossible to plan essential parts of a budget in a right way. That has a great importance in terms of correctness of long-term financial perspectives of the local government units.

  5. Collaboration in Local Economic Development: The Case of Toledo

    Directory of Open Access Journals (Sweden)

    Neil Reid

    2012-01-01

    Full Text Available Many American communities place a high priority on retaining and attracting innovative industries. However, in most American metropolitan areas, the responsibility for local economic development is fragmented along jurisdictional and institutional lines. The result of this fragmentation is that local economic development is often chaotic with no one individual, agency, or jurisdiction in control, which may inhibit the effectiveness of local economic development efforts. To address these challenges and more effectively utilize resources, there has been greater emphasis recently on regional collaboration in local economic development. The purpose of this paper is to measure the extent of collaboration among local economic development professionals in the Toledo, Ohio Metropolitan Statistical Area and to identify the extent to which these interactions constitute a social network. We believe that the existence of a strong social network among economic development professionals is critical to overcome some of the negative effects of jurisdictional and institutional fragmentation. While there is a core network of relatively dense collaboration in northwest Ohio, that network does not span the entire metropolitan area. A high level of local interactions occurs, but there are few “global pipelines” outside the region. A potential challenge for economic development in the region is to avoid “lock in”, which will make it more difficult to attract innovative industries or diversify the economy in order to decrease the traditional dependence on the auto industry.

    International Nuclear Information System (INIS)

    LaBar, M.; Bowers, H.

    1988-01-01

    Reduced load growth and heightened concern with economic risk has led to an expressed utility preference for smaller capacity additions. The Modular High Temperature Reactor (MHTGR) plant has been developed as a small, simple plant that has limited financial risk and is economically competitive with comparatively sized coal plants. Competitive economics is achieved by the simplifications made possible in a small MHTGR, reduction in the quantity of nuclear grade construction and design standardization and certification. Assessments show the MHTGR plant to have an economic advantage over coal plants for plant sizes from 270 MWe to 1080 MWe. Financial risk is limited by small unit sizes and short lead times that allow incremental deployment. Evaluations show the MHTGR incremental deployment capability to reduce negative cash flows by almost a factor of 2 relative to that required by a single large nuclear plant

    2014-12-01

    Full Text Available The purpose of this article is to define nature, basis, and the effects of the economic development policy conducted by local governments in Poland. The analyses carried out are designed to define the role of local authorities in the management of economic development in the area. Furthermore, the purpose of this article is to analyse instruments for supporting economic development, which can be potentially used by local governments in Poland. The realization of this objective is possible by using descriptive methods based on a review of literature and the various types of documents and analysis on the policy of both the economic development and activities of local government, which implement this policy. The method of system analysis is also partially used in the article, and some results of surveys conducted among Polish and foreign investors and entrepreneurs in 2011 are presented. The article assumes that in spite of having a number of instruments, both formal and material, for encouraging economic development and business development, most local governments narrowly assess the current state of entrepreneurship and development trends, and perform an insufficient analysis of the potential of their area. Secondly, the formulated goals of economic development are not very innovative, ambitious or concrete. Furthermore, they do not arise directly from the analysis of the micro and macro-environment that affects the position and development of local government. Key words:

    Full Text Available It is observed that quality of mass produced and highly processed food forces consumers to change their consumption habits and become more interested in locally available food products. Consumers are becoming aware of negative consequences of global food systems. As an alternative, Local Food Systems are gaining on popularity because short food supply chains offer fresh, healthy and not modified products. The popularity of Local Food Systems is reflected in the need for analysing impact and significance of those systems. Thus, this paper presents main benefits of acting locally. Local Food Systems has been reviewed in case of positive economic, environmental and social influence on the region. What is more, the paper presents consumers’ attitude to Local Food Systems. As a conclusion authors justify significance of development and investment in Local Food Systems as an alternative to agriculture networks.

    Directory of Open Access Journals (Sweden)

    Anca Florentina GAVRILUŢĂ (VATAMANU

    2017-12-01

    Full Text Available This work aims to assess the impact of fiscal decentralization on local (regional development in the EU Member States while controlling for macroeconomic and local autonomy specific factors. Using a panel data approach with dynamic effects, we examined the implications of fiscal decentralization on local development across European Union countries over the 1990-2004 period. The novelty of the study is emphasized by including in the analysis a variable which tests local fiscal discipline, more exactly, Fiscal Rule Strength Index for local level of government. Our findings suggest that prosperity of regions, measured in GDP growth depends on variables such as characteristics of decentralization undertaken by each country or local fiscal discipline, confirming our primary hypothesis. This supports the view that recently implemented reforms aiming to enforce fiscal discipline following-up the Fiscal Compact strengthened the local budgetary framework and restrained, therefore, the local discretionary power to act towards development.

  5. INTERCONNECTIONS BETWEEN THE ECONOMIC STRUCTURE OF LOCAL SPENDING AND ECONOMIC GROWTH IN ROMANIA

    Full Text Available The issue of the effects of government interventions, explicitly of the taxes and expenditures of local public authorities, has generated substantial debate over time, and still gives rise to numerous controversies in theory and practice. Following the Keynesian path of reasoning, it is, at least theoretically, admitted that it is possible to influence the socio-economic activities and support for economic growth by means of government spending, but different other factors act towards enhancing or, on the contrary, impeding the achievement of the desired effects. From this point of view, the delimitation of competences and public expenditure responsibilities between different levels of government raises the issue of some possible different effects of the central and local governments’ interventions. As the macroeconomic stabilization function is usually associated with central governments, and the contribution of local governments often is of lesser importance, less attention is paid to the effectiveness of local administrative actions. In such a context, the paper aims to empirically evaluate the effects of the economic structure of local public expenditures on the local (territorial economic growth in Romania, over the period 2007 to 2012. The analysis has been conducted at the level of the 42 Romanian counties and on annual data collected from both international and national sources (World Bank, INSSE, The Romanian Ministry of Regional Development and Public Administration.The general method of estimation is the fixed effects estimation technique for panel data models. Our empirical approach is of absolute novelty, especially for Romania, where previous empirical studies have been focusing on the assessment of the overall effects of general government spending. The main findings of our study are that local public expenditures have a negative impact on territorial economic growth, confirmed both for overall expenditures and for various

    Full Text Available The article examines the impact of social capital characteristics of local communities on the effectiveness of the community-based approach to economic development. The conclusion that such social capital characteristics as (antipaternalism, solidarity and cooperation have the greatest importance for the economic development is made based on the analysis of UNDP and the European Union project “Community-based approach to local development”. It was hypothesized that the creation of community organizations could be an effective mechanism to actualize the existing social capital of rural communities in Ukraine.

    Wills, R.J.; Reuben, B.G.

    1992-01-01

    A recent investigation examined the economic potential for electricity generation in the U.K. using large slow-speed two-stroke diesel engines of around 40MW unit output. Large diesels are a high efficiency technology, resilient to fuel quality, and with high reliability. Economic analysis compared diesels with other generating options for a range of fuel scenarios and discount rates. Merit order potential and total costs were also assessed. The diesels show superior economic qualities, both in terms of investment criteria and high merit position. They are economically comparable with combined cycle gas turbines, but combined cycle plant is essentially large-scale, whereas diesels in 40 MW units sizes can provide small-scale, high-efficiency local generation. Slow-speed diesels represent a sound investment for electricity supply. Diesels in local power stations in southern England would increase supply security and diversity. They are compatible with a cautious investment approach and are appropriate for the new market conditions in electricity supply. (author)

    Perales, Francisco; Plage, Stefanie

    2017-02-01

    Medical research shows that healthy sleep has benefits for human wellbeing. We contribute to the emerging social-epidemiological literature on the social determinants of sleep by considering how living in an area with poor economic circumstances can result in sleep loss through financial worry, uncertainty and stress. We use multilevel regression models and nationally-representative data from the Household, Income and Labour Dynamics in Australia Survey (n = 9181) and find that individuals who live in areas with high unemployment rates or experience individual-level economic vulnerability sleep less than comparable individuals in areas with low unemployment rates, or who do not experience financial hardships. The negative association between local economic conditions and sleep duration is substantially stronger amongst economically vulnerable individuals. This highlights the importance of considering multiple levels in the analysis of health inequalities, as status and location can intersect to produce and reproduce disadvantage systems.

    2017-10-01

    Full Text Available The article is aimed at improving the theoretical and methodical provisions of the cluster approach to development of the spatially localized systems of the agricultural sector of Ukrainian economy at the regional level. Based on generalizing the relevant theoretical provisions, the identified characteristics of formation and development of the spatially localized systems, it has been found that, originating in the form of economic growth zones, they have been transformed into clustered and subclustered forms. It has been indicated that a prospective form of further development of the spatially localized systems is formation of subclustered structures that take account of the established specialization of localities, appropriate infrastructure, resource availability. The possibility of creating a project of developing a cluster formation was discussed on the example of the Central Economic Area. A complex of basic requirements for the intended localization of the cluster has been formulated. Proceeding from the results of the study, practical proposals for strategic management of region have been developed on the basis of development of cluster formations, using the spatially localized agrarian economic systems.

    2014-07-01

    Full Text Available Implementation of the Caribbean Local Economic Development Project (CARILED1began in 2012 in seven countries for a duration of six years, to support sustainable economic growth in the region. CARILED has introduced the idea of local economic development (LED to the ‘development’ debate in the region but has also brought the organisational capacity of local government, and local government’s role as ‘facilitator’ of LED,to the fore. This paper assesses organizational behaviour and capability in local government in Jamaica to determine the state of readiness for a developmental role. The paper draws on two sets of research data to aid its analysis–a capacity audit (CAPAUD conducted in 2010 and an organisational analysis (OAcommissioned by the Ministry of Local Government in 2010, both of which targeted a sample of local authorities in Jamaica. The study found that when assessed against established criteria for an LED organisation, ie: research and information provision; marketing and coordination; learning and innovation; and leadership - local government’s institutional and organisational capacity for development is unevenly distributed. For instance, local leaders understood organisational purpose but efforts to give effect to this appeared undeveloped, sporadic and uni-directional. It was also evident that participatory strategies are used to gain information from communities but these were often devoid of systematic research methodologies rendering formal community impact on local planning negligent. Finally there is strong potential for the kind of administrative leadership required by a developmental local government to evolve,indicated by the quality of training, quantum of managerial/supervisory staff, and stability of staff establishment. However, this potential is threatened by the deficiencies in the non-traditional functional areas that are strategic to the organisation’s effectiveness as a ‘facilitator’ of LED, ie

    Full Text Available In Indonesia, decentralization and globalization has introduced a new spirit for localism. Since decentralisation, regions have been motivated to accelerate economic development through local endowment and resources. The democratic Indonesia government has been interested to follow economy theories and case studies develop in the advance countries. Over the years, government policies have supported and strengthen technology development through industrial clusters and national and regional innovation systems. This research aims to explore current progress of Indonesia innovation system through industrial clusters. The research found the presence of industry clustering and very limited innovation system in Indonesia. The research argues that these activities has significant impact on employment growth, but does not increase the industry's value added.

Numerical experiments show that the immunity of the truncated Localized Waves propagating in dispersive silica to decay and distortion is enhanced as the non-linearity of the relation between the transverse spatial spectral components and the wave vector gets stronger, in contrast to free-space propagating waves, which suffer from early decay and distortion. © 2011 IEEE.

  4. Habitat Maintenance and Local Economic Ethics in Rural Atlantic Canada.

    Science.gov (United States)

    Foster, Karen

    2018-02-01

    Inspired by Jane Jacobs's writing on "habitat maintenance," this paper seeks to identify the ethics that sometimes compel rural residents to act in ways that preserve their communities in the long run, despite short-term incentives to do otherwise. Data from focus groups in four rural Atlantic Canadian communities suggest shared ethics around entrepreneurship, market competition, buying local, and subsistence, some of which underlie the rural practices and perspectives that appear, to some outsiders, as irrational and "backwards." Understanding these ethics and the practices they incite as components of habitat maintenance-and judging them by their situated pragmatism rather than their fit with the placeless ideologies of growth-centric global capitalism and competitiveness-highlights their rationality and utility. Findings could help direct discussions of rural economic development toward notions of prosperity, sustainability, and economy that fit better with rural realities. © 2018 Canadian Sociological Association/La Société canadienne de sociologie.

    2014-11-01

    Employee turnover, defined as total separations from employment, is expensive, can result in lost capacity, and can limit local health departments' (LHDs') ability to respond to public health needs. Despite the importance of workforce capacity in public health, little is known about workforce turnover in LHDs. To examine the extent to which LHDs experience turnover and identify LHD characteristics that are associated with turnover. A cross-sectional data set of employee turnover and LHD characteristics from the 2013 National Profile of LHDs was analyzed. Descriptive statistics and bivariate analyses were conducted in 2014 on turnover rates. The effect of the following LHD characteristics on turnover rates were examined: population size, governance type, degree of urbanization, top executive experience level, expenditures per capita, and LHD budget cuts. In 2013, LHDs experienced a mean turnover rate of 9.88%; approximately one third of turnover was due to retirements. LHDs with shared state and local governance experienced a higher turnover rate than LHDs with exclusive state or local governance. LHDs that are units of state agencies had a significantly higher retirement rate than those governed by local authorities. Top executive experience level, per capita expenditures, and LHD budget cuts were also related to turnover rates. LHDs experienced a lower overall turnover rate than state health departments in 2011 and lower than all local and state government agencies in 2012. Strengthening leadership skills of new top executives and ensuring adequate funding may reduce turnover in LHDs. Copyright © 2014 American Journal of Preventive Medicine. Published by Elsevier Inc.

    2014-10-01

    The aim of this study was to assess potential cost-effectiveness of using a prostate cancer specific functional imaging technology capable of identifying residual localized disease versus small volume metastatic disease for asymptomatic men with low but detectable prostate specific antigen (PSA) elevation following radical prostatectomy. Markov modeling was used to estimate the incremental impact on healthcare system costs (2012 USD) and quality-adjusted life-years (QALYs) of two alternative strategies: (i) using the new diagnostic to guide therapy versus (ii) current usual care-using a combination of computed tomography, magnetic resonance imaging, and bone scan to guide therapy. Costs were based on estimates from literature and Medicare reimbursement. Prostate cancer progression, survival, utilities, and background risk of all-cause mortality were obtained from literature. Base-case diagnostic sensitivity (75 percent), specificity (90 percent), and cost (USD 2,500) were provided by our industry partner GE Healthcare. The new diagnostic strategy provided an average gain of 1.83 (95 percent uncertainty interval [UI]: 1.24-2.64) QALYs with added costs of USD 15,595 (95 percent UI: USD -6,330-44,402) over 35 years. The resulting incremental cost-effectiveness ratio was USD 8,516/QALY (95 percent UI: USD -2,947-22,372). RESULTS were most influenced by the utility discounting rate and test performance characteristics; however, the new diagnostic provided clinical benefits over a wide range of sensitivity and specificity. This analysis suggests a diagnostic technology capable of identifying whether men with biochemical recurrence after radical prostatectomy have localized versus metastatic disease would be a cost-effective alternative to current standard work-up. The results support additional investment in development and validation of such a diagnostic.

    2005-01-01

    This paper describes the application of the Uniform Geometrical Theory of Diffraction (UTD) for Space Station Wireless Local Area Networks (WLANs) indoor propagation characteristics analysis. The verification results indicate good correlation between UTD computed and measured signal strength. It is observed that the propagation characteristics are quite different in the Space Station modules as compared with those in the typical indoor WLANs environment, such as an office building. The existing indoor propagation models are not readily applicable to the Space Station module environment. The Space Station modules can be regarded as oversized imperfect waveguides. Two distinct propagation regions separated by a breakpoint exist. The propagation exhibits the guided wave characteristics. The propagation loss in the Space Station, thus, is much smaller than that in the typical office building. The path loss model developed in this paper is applicable for Space Station WLAN RF coverage and link performance analysis.

    Full Text Available The study assessed the role and importance of Local Economic Development as a means of enhancing urban development paying particular attention to the regulators of Local Economic Development in Harare. Local Economic Development is a process which encourages partners from the community, public sector, private sector and non-governmental sectors to work collectively to create better conditions for economic growth and employment generation with the aim of improving the locality economic future and the quality of life for all citizens. The study was premised on the theory of competitive advantage which puts up that prosperity and wealth creation is determined by microeconomic factors and that prosperity means increasing the standards of living for the local people and ultimately their quality of life. Primary data for the research was gathered through observation and key informant interviews. Data on key stakeholders understanding on the concept of Local Economic Development, how it is being practised and how the current regulatory framework enhance or impinge on local people’s participation in Local Economic Development was collected. Secondary data was also collected from Harare’s 2014 budget, census and existing forward plans. The study revealed that the practice of Local Economic Development in Harare is biased towards the setting aside of land zoned for industrial and commercial uses and implementation of development control parameters. Small to Medium Enterprises and the informal sector have also been identified as the major forms of Local Economic Development that citizens are involved in. However, the study revealed that proper policy frameworks which guide practice of Local Economic Development initiatives were missing

In this way the paper argues, local authorities could utilize local resources to ignite local economic development (LED through for instance trade activities and investments.LED initiatives aim at empowering local stakeholders to utilise business enterprises, labour, capital and other local resources effectively to maximise local benefits in order to contribute to poverty reduction and the uplifting of citizens life conditions. The paper is divided into four major parts. The first part gives a background of the notion of decentralisation, urbanisation and local economic development. The second part provides an overview of the review of the related literature while the third part gives an account on how the above are inter-related. The fourth part provides the challenges faced by urbanisation in achieving local economic development and part five is presented as conclusion and recommendations.

This paper presents an international political economy perspective on the past and present labor crises in the GCC countries and makes suggestions for improving the qualities and conditions of national and foreign work force. It is concluded that the GCC would survive in the post-carbon era, provided that economic diversification went coordinately with necessary adjustments in the labor sector

    Full Text Available The article deals with the S. Sassen’s research and writing focuses on globalization (including social, economic and political dimensions, global cities, migration, the new networked technologies, and changes within the liberal state that result from current transnational conditions. The main features of the global cities are examined on examples. The global economy is far from being placeless, has and needs very specific territorial insertions, and that this need is sharpest in the case of highly globalized and electronic sectors such as finance. Large corporate firms needed access to a whole new mix of complex specialized services almost impossible to produce in-house as had been the practice. This new economic logic would generate high-level jobs and lowwage jobs; it would need far fewer middle-range jobs than traditional corporations. The transformation of the socio-economic systems at the global and national levels, the associated changes of urban communities life is considered.

    Strategies for localizing parathyroid pathology preoperatively vary in cost and accuracy. Our purpose was to compute and compare comprehensive costs associated with common localization strategies. A decision-analytic model was developed to evaluate comprehensive, short-term costs of parathyroid localization strategies for patients with primary hyperparathyroidism. Eight strategies were compared. Probabilities of accurate localization were extracted from the literature, and costs associated with each strategy were based on 2011 Medicare reimbursement schedules. Differential cost considerations included outpatient versus inpatient surgeries, operative time, and costs of imaging. Sensitivity analyses were performed to determine effects of variability in key model parameters upon model results. Ultrasound (US) followed by 4D-CT was the least expensive strategy ($5,901), followed by US alone ($6,028), and 4D-CT alone ($6,110). Strategies including sestamibi (SM) were more expensive, with associated expenditures of up to $6,329 for contemporaneous US and SM. Four-gland, bilateral neck exploration (BNE) was the most expensive strategy ($6,824). Differences in cost were dependent upon differences in the sensitivity of each strategy for detecting single-gland disease, which determined the proportion of patients able to undergo outpatient minimally invasive parathyroidectomy. In sensitivity analysis, US alone was preferred over US followed by 4D-CT only when both the sensitivity of US alone for detecting an adenoma was ≥ 94 %, and the sensitivity of 4D-CT following negative US was ≤ 39 %. 4D-CT alone was the least costly strategy when US sensitivity was ≤ 31 %. Among commonly used strategies for preoperative localization of parathyroid pathology, US followed by selective 4D-CT is the least expensive.

  12. ENTERPRISE ECONOMIC SECURITY: ESSENTIAL CHARACTERISTICS OF THE CONCEPT

    Full Text Available The subjectmatter of the study is determining the essence of economic security. The aim is to systematize the approaches to the interpretation of the concept "enterprise economic security". The immediacy of the study is motivated by the lack of consistency, co-ordination and common views on the discourse in this area, as well as insufficiently substantiated offers for implementing modern methods and models of economic security management at all levels of economy. At the same time, despite a large number of publications, there remain many unsolved problems in the management of economic security, which is the main component of protection against threats, both at the state level and at the level of business entities such as enterprises and organizations. The following methods of theoretical and empirical research were used: logical generalization – to substantiate the relevance of the topic, the goals and objectives of the study, to determine the essential features of the problem; analysis and synthesis – to describe the theories of economic security. Economic security of an enterprise gives rise to a company’s capability to develop, increase its competitiveness and the competitiveness of its products, sustain its position on competitive markets, and characterizes the strength and economic potential of enterprises to counteract the negative impact of the external and internal environment. At the same time, the company’s economic security mirrors the conditions of its protection against any threats which are achieved due to the use of existing and potential resources of the company in order to ensure its safe operation in the long run.

    Innovation and entrepreneurship have the potential to stimulate economic growth. Yet it remains unclear whether top-down or bottom-up innovations are more likely to lead to local economic development. By looking at three cases of frugal innovation on the Zambian Copperbelt, in the spheres of housing, water and energy, it will be argued that polycentric innovation (which connects local and international actors) is most likely to generate inclusive development.

  16. Navigating catastrophes: Local but not global optimisation allows for macro-economic navigation of crises

    Science.gov (United States)

    Harré, Michael S.

    2013-02-01

    Two aspects of modern economic theory have dominated the recent discussion on the state of the global economy: Crashes in financial markets and whether or not traditional notions of economic equilibrium have any validity. We have all seen the consequences of market crashes: plummeting share prices, businesses collapsing and considerable uncertainty throughout the global economy. This seems contrary to what might be expected of a system in equilibrium where growth dominates the relatively minor fluctuations in prices. Recent work from within economics as well as by physicists, psychologists and computational scientists has significantly improved our understanding of the more complex aspects of these systems. With this interdisciplinary approach in mind, a behavioural economics model of local optimisation is introduced and three general properties are proven. The first is that under very specific conditions local optimisation leads to a conventional macro-economic notion of a global equilibrium. The second is that if both global optimisation and economic growth are required then under very mild assumptions market catastrophes are an unavoidable consequence. Third, if only local optimisation and economic growth are required then there is sufficient parametric freedom for macro-economic policy makers to steer an economy around catastrophes without overtly disrupting local optimisation.

  17. The effects of local government investment on economic growth and employment: evidence from transitional China

    2009-01-01

    Based on the panel data of 28 provinces in the year of 1987-2001,this paper examines the effects of the local government investment on economic growth and employment.The empirical result shows that the local government investment plays a significant positive role in economic growth and emplovment.However,while the proportion of local government investment to GDP had a remarkable rise after 1998.the elasticity of local government investment on economic growth declined,which shows that there is a hig room for raising the efficiency of local government mvestment.Moreover,the empirical examination shows that although local government investment had positive effect on employment,the elasticity had a decrease after 1994 when the tax-sharing system reform was put into practice.This shows that the positive role of local government investment on emplovment is also limited.This paper argues that the role of local governments as investors must be weakened,and local governments of different levels should lessen direct economic intervention and concentrate on public regulation.

    Science.gov (United States)

    Barth, Jannette M

    2013-01-01

    It is often assumed that natural gas exploration and development in the Marcellus Shale will bring great economic prosperity to state and local economies. Policymakers need accurate economic information on which to base decisions regarding permitting and regulation of shale gas extraction. This paper provides a summary review of research findings on the economic impacts of extractive industries, with an emphasis on peer-reviewed studies. The conclusions from the studies are varied and imply that further research, on a case-by-case basis, is necessary before definitive conclusions can be made regarding both short- and long-term implications for state and local economies.

  20. From Family Based to Industrial Based Production: Local Economic Development Initiatives and the HELIX Model

    Directory of Open Access Journals (Sweden)

    Bartjan W Pennink

    2013-01-01

    Full Text Available To build a strong local economy, good practice tells us that each community should undertake a collaborative, strategically planned process to understand and then act upon its own strengths, weaknesses, opportunities and threats. From this perspective we start with the local communities but how is this related to the perspective from the Helix model in which three actors are explicitly introduced: the Government, the Industry and the Universities? The purpose of local economic development (LED is to build up the economic capacity of a local area to improve its economic future and the quality of life for all. To support  the Local Economic Development in remote areas,   a program  has been developed based on the LED frame work of the world bank. This approach and  the experiences over  the past years with this program are  described in the first part.  In the second part of the paper, We analyse work done with that program with the help of the social capital concept and the triple helix model.  In all cases it is important to pay attention to who is taken the initiative after the first move (and it is not always the governance as actor and for the triple helix we suggest  that the concepts of (national Government, Industry and University need a translation to Local Governance Agency, Cooperation or other ways of cooperation of local communities and Local Universities. Although a push from outside might help  a local region in development the endogenous factors are  also needed.

    The National Park Service (NPS) manages the Nation’s most iconic destinations that attract millions of visitors from across the Nation and around the world. Trip-related spending by NPS visitors generates and supports a considerable amount of economic activity within park gateway communities. This economic effects analysis measures how NPS visitor spending cycles through local economies, generating business sales and supporting jobs and income. In 2016, the National Park System received an estimated 330,971,689 recreation visits. Visitors to National Parks spent an estimated $18.4 billion in local gateway regions (defined as communities within 60 miles of a park). The contribution of this spending to the national economy was 318 thousand jobs, $12.0 billion in labor income, $19.9 billion in value added, and $34.9 billion in economic output. The lodging sector saw the highest direct contributions with $5.7 billion in economic output directly contributed to local gateway economies nationally. The sector with the next greatest direct contributions was the restaurants and bars sector, with $3.7 billion in economic output directly contributed to local gateway economies nationally.

  12. CHARACTERISTICS OF THE ECONOMIC - FINANCIAL CRISIS IN EUROPE

    Directory of Open Access Journals (Sweden)

    Georgeta-Mădălina MEGHIŞAN

    2012-04-01

    Full Text Available The current economic and financial crisis represents the most sever episode of this type during the last generations – as it results from the reports of the European Commission. The impact upon the European Union member states’ economies materialised under the form of the credit restructuration, reduction of the trust at the economic level, and also, a serious contraction of the demand and the commercial exchanges. These are elements which determined the decrease of the investment and production activity, and also the usage of the production capacities, especially in the constructions field. On a medium and long term, we can appreciate that the true problem of the nature and profoundness of the crisis represents the pressure upon the business competitiveness, with consequences at the level of the working force or degradation of the human and technologic capital.

    2015-12-01

    Full Text Available A strong underlying structure in the economic, demographic, and entrepreneurial domains of local authorities (municipalities in the Free State, South Africa was detected through cluster and other analyses. The structure is indicative of a system in which economic value addition, population size, employment creation, and entrepreneurial domains are dynamically linked. The agriculture, mining, and fuel and chemicals sectors dominate the economic value addition in some municipalities, whereas others are without a single dominating economic sector (i.e. they have well-balanced economies. The agriculture and households sectors are significant sources of employment in all municipalities. Cluster sequence analyses of the municipalities revealed statistically significant recurring patterns of value addition, employment, and entrepreneurship, further strengthening the detection of orderliness, which can promote mutual learning. The Metsimaholo municipality with a significant manufacturing base is an atypical Free State municipality and provides an outstanding example of the economic, demographic, and entrepreneurial impacts of value addition to local or external primary products.

    2011-01-01

    This study assesses the potential of an integrated methodology for predicting local trends in invasive exotic plant species (invasive richness) using indirect, regional information on human disturbance. The distribution of invasive plants was assessed in North Portugal using herbarium collections and local environmental, geophysical and socio-economic characteristics. Invasive richness response to anthropogenic disturbance was predicted using a dynamic model based on a sequential modeling process (stochastic dynamic methodology-StDM). Derived scenarios showed that invasive richness trends were clearly associated with ongoing socio-economic change. Simulations including scenarios of growing urbanization showed an increase in invasive richness while simulations in municipalities with decreasing populations showed stable or decreasing levels of invasive richness. The model simulations demonstrate the interest and feasibility of using this methodology in disturbance ecology. - Highlights: → Socio-economic data indicate human induced disturbances. → Socio-economic development increase disturbance in ecosystems. → Disturbance promotes opportunities for invasive plants.→ Increased opportunities promote richness of invasive plants.→ Increase in richness of invasive plants change natural ecosystems.

    Full Text Available Load associated fatigue cracking is one of the major distress types occurring in flexible pavement systems. Flexural bending beam fatigue laboratory test has been used for several decades and is considered to be an integral part of the new superpave advanced characterization procedure. One of the most significant solutions to prolong the fatigue life for an asphaltic mixture is to utilize flexible materials as rubber. A laboratory testing program was performed on a conventional and Asphalt Rubber- (AR- gap-graded mixtures to investigate the impact of added rubber on the mechanical, mechanistic, and economical attributes of asphaltic mixtures. Strain controlled fatigue tests were conducted according to American Association of State Highway and Transportation Officials (AASHTO procedures. The results from the beam fatigue tests indicated that the AR-gap-graded mixtures would have much longer fatigue life compared with the reference (conventional mixtures. In addition, a mechanistic analysis using 3D-Move software coupled with a cost analysis study based on the fatigue performance on the two mixtures was performed. Overall, analysis showed that AR modified asphalt mixtures exhibited significantly lower cost of pavement per 1000 cycles of fatigue life per mile compared to conventional HMA mixture.

  7. A method for estimating the local area economic damages of Superfund waste sites

    International Nuclear Information System (INIS)

    Walker, D.R.

    1992-01-01

    National Priority List (NPL) sites, or more commonly called Superfund sites, are hazardous waste sites (HWS) deemed by the Environmental Protection Agency (EPA) to impose the greatest risks to human health or welfare or to the environment. HWS are placed and ranked for cleanup on the NPL based on a score derived from the Hazard Ranking System (HRS), which is a scientific assessment of the health and environmental risks posed by HWS. A concern of the HRS is that the rank of sites is not based on benefit-cost analysis. The main objective of this dissertation is to develop a method for estimating the local area economic damages associated with Superfund waste sites. Secondarily, the model is used to derive county-level damage estimates for use in ranking the county level damages from Superfund sites. The conceptual model used to describe the damages associated with Superfund sites is a household-firm location decision model. In this model assumes that households and firms make their location choice based on the local level of wages, rents and amenities. The model was empirically implemented using 1980 census microdata on households and workers in 253 counties across the US. The household sample includes data on the value and structural characteristics of homes. The worker sample includes the annual earnings of workers and a vector worker attributes. The microdata was combined with county level amenity data, including the number of Superfund sites. The hedonic pricing technique was used to estimate the effect of Superfund sites on average annual wages per household and on monthly expenditures on housing. The results show that Superfund sites impose statistically significant damages on households. The annual county damages from Superfund sites for a sample of 151 counties was over 14 billion dollars. The ranking of counties using the damage estimates is correlated with the rank of counties using the HRS

    Full Text Available Groundnut an important oil seed crop provides significant sources of cash through the sales of seed, cakes, oil and haulms. Groundnut plays an important role in the diets of rural populations. Groundnut pod yields from farmer’s field are low, averaging about 800 kg per ha, less than one-third the potential yield of 3000 kg per ha. This large gap is of concern and in view of this, the study was carried out to assess the socio economic characteristics of groundnut farmers, determine the level of profitability of groundnut production, the resource use efficiency as well as to find out problems encountered in groundnut production in Sabon-gari local government area. Seventy-nine farmers involved in groundnut production were randomly selected from the various farms located within the local government area. Data were collected using primary and secondary sources. To examine the profitability of groundnut production, the gross margin and cost benefit analysis were carried out. The result of the study shows that experienced farmers are less involved in groundnut production and most groundnut farmers are engaged in other form of businesses. The cost, availability, and lack of technical knowledge of inputs requirements are responsible for poor use of the inputs. Labour, fertilizer, seed and herbicides are all over utilized except insecticide which is underutilized. Among the problems encountered in groundnut production in the study are lacks of capital and extension services. These two problems accounted for over 78% of the problem of groundnut in the study area. It is therefore recommended that government and research institutes should strengthen extension services to deliver improved technologies to the farmers. Farmers are also advised to source for loans through cooperatives, banks and other available sources at low charges and the procedure for loan should be made simple to enable farmers’ access loans so that groundnut production can be improved.

    Full Text Available Local autonomy is a rarely explored concept in the literature, still holding an increasing importance in the current context of Romania’s development in the European Union. In this paper we attempt to provide an overall survey on the financial dimension of local autonomy, assuming that local autonomy cannot be implemented, unless local authorities have adequate financial resources. In this study we also analyze the possibility to measure the local revenue autonomy and to identify the variables which represent the determinants of the local revenue autonomy. Using empirical evidence from Romanian counties, we analyze the regional distributions for own revenues and for the significant determinants of local revenue autonomy. By means of econometric modeling we will highlight the variables which are statistically significant and explain the variation of the local revenues of Romanian counties, as well as the order of importance of the determinants of local financial autonomy. The empirical results show us that, although, theoretically, the counties have a great administrative and financial autonomy, practically this autonomy is very reduced (an average of under 40% for local revenue. The modeling results show that the degree of local financial autonomy can be increased by increasing economic development, urbanization, the average living area per person and fertility. Unemployment and a high level of demographic dependency contribute to the decrease of local financial autonomy.

    Full Text Available Public administration is an area with particularly social impact over all members of society. In the autonomous administrative authorities, local councils have important responsibilities in the organization of local community life. Within these councils several specialized committees operate and those that have the highest volume of activity are usually economic and legal committee. Their role is to filter out under a particular form, the specific procedure being the approval of local initiatives in the field of specific activity, namely economic and financial and legal. The effects of this operation need to be reflected in the adoption of decisions that meet not only the initiator's intentions, but also the point of view of local elected officials who are specialized in a particular area and reunited within the previous committees.

    The acerola (Malpighia emarginata Sessé y Mociño ex DC) is a wild plant grown in zones of tropical and subtropical climate. Acerola is origin from South of Mexico, Central America and Septentrional area of South America. Its scientific name was adopted in 1986 by the International Council of Vegetable Genetic Resources. Malpighia emarginata has a subglobulose drupa fruit with three seeds which account between the 19 - 25% of the total weight. The diameter and weight of the fruit varies between 1 - 4 cm and 2 - 15 g, respectively. The fruit shows green color when it is developing, which changes to yellow and red tones when it is mature. Each plant produces annually 20 - 30 kg of fruits. This fruit contents macro and micronutrients: proteins (0.21-0.80 g/100 g), fats (0.23-0.80 g/100 g), carbohydrates (3.6-7.80 g/100 g), mineral salts (iron 0.24, calcium 11.7, phosphorus 17.1 mg/100 g) and vitamins (thiamine 0.02, riboflavine 0.07, piridoxine 8.7 mg/100 g). Its high content in vitamin C (695 a 4827 mg/100 g) is remarkable, therefore acerola has an increasing economic value by its great consume during last years. Acerola also presents carotenoids and bioflavonoids which provide important nutritive value and its potential use as antioxidant. Brazil has a climate and soil appropriate for the culture of acerola, thus this country is the main mundial productor. Acerola is commercialised as juices, jams, ices, gelatins, sweets or liquors. Bibliographical data have been mainly supplied by Electronic Resources of the University of Seville and the University do Vale do Itajaí (Santa Catarina, Brazil).

    Fibromyalgia (FM) is characterized by widespread pain that can lead to significant patient disability, complex management decisions for physicians, and economic burden on society. We investigated the total costs of FM in an employer population. Administrative claims data of a Fortune 100 manufacturer were used to quantify direct (i.e., medical and pharmaceutical claims) and indirect (i.e., disability claims and imputed absenteeism) costs associated with FM. A total of 4699 patients with at least one FM claim between 1996 and 1998 were contrasted with a 10% random sample of the overall beneficiary population. Employee-only subsets of both samples also were drawn. Medical utilization, receipt of prescription drugs, and annual total costs were proportionately similar yet significantly greater among FM claimants than the overall sample (all p < 0.0001). Total annual costs for FM claimants were $5945 versus $2486 for the typical beneficiary (p < 0.0001). Six percent of these costs were attributable to FM-specific claims. The prevalence of disability was twice as high among FM employees than overall employees (p < 0.0001). For every dollar spent on FM-specific claims, the employer spent another $57 to $143 on additional direct and indirect costs. Hidden costs of disability and comorbidities greatly increase the true burden of FM. Regardless of the clinical understanding of FM, when a claim for FM is present, considerable costs are involved. Findings suggest that within the management of FM there may be large cost-offset opportunities for reductions in patient, physician, and employer burdens.

    Human mating and reproductive behaviour can vary depending on various mechanisms, including the local sex ratio. Previous research shows that as sex ratios become female-biased, women from economically deprived areas are less likely to delay reproductive opportunities to wait for a high-investing mate but instead begin their reproductive careers sooner. Here, we show that the local sex ratio also has an impact on female fertility schedules. At young ages, a female-biased ratio is associated w...

  14. Including capabilities of local actors in regional economic development: Empirical results of local seaweed industries in Sulawesi

    2013-11-01

    Full Text Available Stimson, et al. (2009 developed one of the most relevant and well known model for Regional Economic Development. This model covers the most important factors related to economic development question. However, this model excludes the social components of development. Local community should be included in terms of the development of a region. This paper introduced to the Stimson model “Skills” and “Knowledge” at the individual level for local actors indicating the capabilities at the individual level and introduced “Human Coordination” for the capabilities at the collective level. In our empirical research we looked at the Indonesian seaweed market with a specific focus on the region of Baubau. This region was chosen because there are hardly any economic developments. Furthermore this study focuses on the poorer community who are trying to improve their situation by the cultivation of Seaweed. Eighteen local informants was interviewed besides additional interviews of informants from educational and governmental institutions in the cities of Jakarta, Bandung and Yogyakarta. The informants selected had a direct or indirect relationship with the region of Baubau. With the support of the empirical data from this region we can confirm that it is worthwhile to include the local community in the model for regional economic development.  The newly added variables: at the individual level; Skills and Knowledge and at the level of the collective: Human Coordination was supported by the empirical material. It is an indication that including the new variables can give regional economic an extra dimension.  In this way we think that it becomes more explicit that “endogenous” means that the people, or variables closely related to them, should be more explicitly included in models trying to capture Regional Economic Development or rephrased as Local Economic Development Keywords:Regional and endogenous development; Fisheries and seaweed

    Full Text Available La primacía de los rasgos globales de una forma visual sobre los locales, o viceversa, es todavía una cuestión sin resolver. Algunos autores han señalado que la precedencia global sucede cuando se iguala la excentricidad de los niveles global y local mediante la utilización de estímulos concéntricos. Sin embargo, otras investigaciones con patrones visuales similares han obtenido precedencia local. El presente trabajo incluye dos experimentos planificados para arrojar luz sobre la interpretación de estos resultados inconsistentes. En conjunto, se pretende analizar si la diferencia en la densidad estimular utilizada en los distintos experimentos o la diferencia en el tipo de tarea pueden ser hipótesis plausibles para explicar la obtención de los resultados contradictorios. En el primer experimento, bajo condiciones de atención selectiva y dividida, se incluye una tarea de detección de una figura-objetivo en el estímulo con un tiempo de exposición de 150 msg. y con estímulos concéntricos con mayor número de elementos locales que los empleados en experimentos previos (Blanca, López, Luna, Zalabardo y Rando, 2000; 2001. Los resultados apuntan a una ausencia de ventaja global o local y a una interferencia bidireccional para la condición de atención selectiva, y bidreccional pero asimétrica para la condición de atención dividida, siendo mayor la interferencia global. En el segundo experimento, se instruye a los sujetos para que indiquen la dirección, izquierda o derecha, de la apertura de un semicírculo en el nivel pertinente, según la condición de dirección de la atención. Los estímulos se presentan con un tiempo de exposición de 150 msg. o ilimitado.

  17. State and local economic impacts from wind energy projects: Texas case study

    International Nuclear Information System (INIS)

    Slattery, Michael C.; Lantz, Eric; Johnson, Becky L.

    2011-01-01

    This paper uses the Jobs and Economic Development Impacts (JEDI) model to estimate economic impacts from 1398 MW of wind power development in four counties in west Texas. Project-specific impacts are estimated at the local level (i.e., within a 100-mile radius around the wind farms) and at the state level. The primary economic policy question addressed is how investment in wind energy affects the state and local communities where the wind farms are built. During the four-year construction phase approximately 4100 FTE (full time equivalents) jobs were supported with turbine and supply chain impacts accounting for 58% of all jobs generated. Total lifetime economic activity to the state from the projects equated to more than $1.8 billion, or $1.3 million per MW of installed capacity. The total economic activity to the local communities was also substantial, equating to nearly $730 million over the assumed 20-year life cycle of the farms, or $0.52 million per MW of installed capacity. Given the current level of impacts observed, and the potential for increased impacts via greater utilization of instate manufacturing capacity and the development of trained wind industry specific laborers, Texas appears to be well positioned to see increasing impacts from continued wind development. - Highlights: ► We use the JEDI model to assess economic impacts from wind development in west Texas. ► Total lifetime economic impact from 1398 MW wind equated to more than $1.8 billion. ► Texas is well positioned to see increasing impacts from continued wind development.

    Full Text Available The Langkawi Island is a popular tourist destination in Malaysia, which development started in the 1990s. To date, it is among the ten islands most visited by local and foreign tourists. The development of Langkawi Island has influenced the economic structure of local community, of which, envisaged as a symbol to help the community especially in the changing economic environment due to its ability to generate income, employment and raise living standards. Therefore, this study aimed to examine the local community’s involvement and perceptions on changes in employment pattern and incomes stimulated by the tourism development in Langkawi. This study conducted a self-administered household survey and had successfully retrieved 398 respondents. From the findings, results showed that local community experienced employment opportunities which in return contributed to an increase in household income. It is therefore, notable investment on tourism development should be of interests to the government as this helps in ensuring the local community’s economic benefits.

    2018-04-01

    Full Text Available This study examines the relationship between public expenditure within regional autonomy policy and economic growth in West Papua and Papua provinces. We distinguish two kinds of expenditure’s decentralization – operational and capital – and also private expenditures. We use an unbalanced panel data over the period of 2007-2010 to investigate those expenditures, whether they enhance regional economic growth or not. We find that the government’s operating and private expenditures have a positive effect on local economic growth, but there is no relationship between capital expenditure’s decentralization on economic growth. The findings did not conform to a-priori efficiency expectations, which suggest needing to reform regional autonomy and fiscal decentralization policy in both provinces.

  1. Economic impact of the energy transition at the local level. Methodologies and case studies

    2014-12-01

    An understanding of the mechanisms that link the energy transition to the stimulation of the economy on the ground is indispensable in terms of more efficient targeting of local energy transition policies. Objective evidence of economic results is required, as is a better understanding of economic analysis methods, in order to equip local and regional authorities with the tools required to demonstrate the economic benefits for all the key players. With the 'Economic impact of the energy transition at a local level - Methodologies and case studies' study, Energy Cities illustrates numerous socio-economic aspects of the energy transition and confirms the local economic benefits, through the use of data. As with any complex, new and diffuse process, this field of research is still not fully understood. Appropriate, high-quality analysis at the local level has rarely been carried out to date and a critical assessment of the methods used is necessary. This study will fill a gap and provide suggestions on potential areas for further research in a range of fields which should be further explored and examined in collaboration with local authorities and voluntary partners. Methodology and results The first part of the study sets out the scope of the study and contains a general description of the impact observed and the potential outcome of transition policies in the main green growth sectors: eco-innovation, the energy performance of buildings, renewable energy, sustainable mobility, recycling and industrial ecology. The analysis then focuses on the feedback of six towns and regions with a policy of active sustainable development (building renovation, support for eco-industries, promotion of soft mobility etc.), presented from the point of view of the economic results observed and the evaluation methods used. The study comprises five European authorities - Brussels, Copenhagen, Hannover, Kirklees and the Greater Paris Region, and one North American authority - Nolan County

  2. Characteristics of the local cutaneous sensory thermoneutral zone

    Zhang, Hui; Arens, Edward A.

    2017-01-01

    Skin temperature detection thresholds have been used to measure human cold and warm sensitivity across the temperature continuum. They exhibit a sensory zone within which neither warm nor cold sensations prevail. This zone has been widely assumed to coincide with steady-state local skin temperatures between 32 and 34°C, but its underlying neurophysiology has been rarely investigated. In this study we employ two approaches to characterize the properties of sensory thermoneutrality, testing for each whether neutrality shifts along the temperature continuum depending on adaptation to a preceding thermal state. The focus is on local spots of skin on the palm. Ten participants (age: 30.3 ± 4.8 yr) underwent two experiments. Experiment 1 established the cold-to-warm inter-detection threshold range for the palm’s glabrous skin and its shift as a function of 3 starting skin temperatures (26, 31, or 36°C). For the same conditions, experiment 2 determined a thermally neutral zone centered around a thermally neutral point in which thermoreceptors’ activity is balanced. The zone was found to be narrow (~0.98 to ~1.33°C), moving with the starting skin temperature over the temperature span 27.5–34.9°C (Pearson r = 0.94; P cold-to-warm inter-threshold range (~2.25 to ~2.47°C) but is only half as wide. These findings provide the first quantitative analysis of the local sensory thermoneutral zone in humans, indicating that it does not occur only within a specific range of steady-state skin temperatures (i.e., it shifts across the temperature continuum) and that it differs from the inter-detection threshold range both quantitatively and qualitatively. These findings provide insight into thermoreception neurophysiology. NEW & NOTEWORTHY Contrary to a widespread concept in human thermoreception, we show that local sensory thermoneutrality is achievable outside the 32–34°C skin temperature range. We propose that sensory adaption underlies a new mechanism of temperature

    A succinct experimental scheme is demonstrated to generate a localized hollow beam by using a π-phase binary bitmap and a convergent thin lens. The experimental results show that the aspect ratio of the dark-spot size of the hollow beam can be effectively controlled by the focal length of the lens. The measured beam profiles in free space also agree with the theoretical modeling. The studies hold great promise that such a hollow beam can be used to cool trapped atoms (or molecules) by Sisyphus cooling and to achieve an optically-trapped Bose–Einstein condensate by optical-potential evaporative cooling.

    The present study quantifies the reduction in the levelized cost of electricity (LCoE) and capital expenditure (CAPEX) of a dish Stirling power plant (DSPP) through an increase in localization and unit production volume. Furthermore, the localization value of the plant is examined to determine how much investment is brought into the local economy. Ouarzazate, Morocco, was chosen as the location of the study due to the country's favorable regulatory framework with regards to solar power technologies and its established industry in the concentrating solar power (CSP) field. A detailed techno-economic model of a DSPP was developed using KTH's in-house modelling tool DYESOPT, which allows power plant evaluation by means of technical and economic performance indicators. Results on the basis of LCoE and CAPEX were compared between two different cases of production volume, examining both a minimum and maximum level of localization. Thereafter, the DSPP LCoE and localization value were compared against competing solar technologies to evaluate its competitiveness. In addition, a sensitivity analysis was conducted around key design parameters. The study confirms that the LCoE of a DSPP can be reduced to values similar to solar photovoltaic (PV) and lower than other CSP technologies. Furthermore, the investment in the local economy is far greater when compared to PV and of the same magnitude to other CSP technologies. The competiveness of a DSPP has the potential to increase further when coupled with thermal energy storage (TES), which is currently under development.

    Full Text Available This article explores the role of multi-level governance and power structures in local water security through a case study of the Nawalparasi district in Nepal. It focuses on economic sustainability as a measure to address water security, placing this thematic in the context of a complicated power structure consisting of local, district and national administration as well as external development cooperation actors. The study aims to find out whether efforts to improve the economic sustainability of water schemes have contributed to water security at the local level. In addition, it will consider the interactions between water security, power structures and local equality and justice. The research builds upon survey data from the Nepalese districts of Nawalparasi and Palpa, and a case study based on interviews and observation in Nawalparasi. The survey was performed in water schemes built within a Finnish development cooperation programme spanning from 1990 to 2004, allowing a consideration of the long-term sustainability of water management projects. This adds a crucial external influence into the intra-state power structures shaping water management in Nepal. The article thus provides an alternative perspective to cross-regional water security through a discussion combining transnational involvement with national and local points of view.

  8. Measuring the Economic Impact of Rural Tourism Membership on Local Economy: A Korean Case Study

    Full Text Available The implementation of rural tourism membership can aid in boosting economic growth in rural areas. This study examines households’ preferences for rural tourism experience in association with sales of local agricultural products. Using a choice experiment method developed by experimental designs, this paper examines households’ preferences to trade off purchasing costs of local agricultural products against various benefits provided by the rural tourism membership. The methods utilized in this paper represent an effective approach to evaluate the value of local tourism resources and the influence of these resources on the local economy. In empirical estimation we applied econometric approaches that allow for different preferences by incorporating income and residence effects into the models. Findings reveal that respondents place a premium on tourism attributes such as invitation seats and outdoor adventure tickets when choosing a tourism membership. We also find that the economic impacts associated with inducing higher-level tourism membership are substantial. This paper illustrates the potential for the development of a strategy associated with rural tourism management to enhance the local economy.

    The roles of state and local agencies in planning for and managing social and economic impacts of nuclear power plants are studied. In order to be effective in these roles state and local agencies must work with each other as well as the NRC. A comparative case study approach is used which analyzes six sites in three West Coast states. The case studies included plants in operation, plants under construction, and plants still in the planning stages. In contrast to some states, all three of these states have moderately centralized procedures for siting power plants, and all have strong environmental laws

    The paper discusses economic benefits which influenced the choice of a broadband local area network for a power plant instead of an alternative multi-cable communication network. Broadband communication networks can offer significant economies over alternative technologies. One-time, cost avoidance savings and recurring annual savings are estimated to total $5.1 million in the first year. The cost/benefit analysis presented here can be used as a guide by other utilities to analyze communication networking alternatives. The paper also includes a discussion of local area network attributes relevant to the power plant installation

    2018-01-01

    Objectives. To demonstrate the benefits-mapping software Environmental Benefits Mapping and Analysis Program-Community Edition (BenMAP-CE), which integrates local air quality data with previously published concentration–response and health–economic valuation functions to estimate the health effects of changes in air pollution levels and their economic consequences. Methods. We illustrate a local health impact assessment of ozone changes in the 10-county nonattainment area of the Dallas–Fort Worth region of Texas, estimating the short-term effects on mortality predicted by 2 scenarios for 3 years (2008, 2011, and 2013): an incremental rollback of the daily 8-hour maximum ozone levels of all area monitors by 10 parts per billion and a rollback-to-a-standard ambient level of 65 parts per billion at only monitors above that level. Results. Estimates of preventable premature deaths attributable to ozone air pollution obtained by the incremental rollback method varied little by year, whereas those obtained by the rollback-to-a-standard method varied by year and were sensitive to the choice of ordinality and the use of preloaded or imported data. Conclusions. BenMAP-CE allows local and regional public health analysts to generate timely, evidence-based estimates of the health impacts and economic consequences of potential policy options in their communities.

    2016-01-01

    Full Text Available In this paper is a detailed analysis of the basics in the theory of economic development during the period from mid last century until today. It states the most significant theories, points out their ranges, offers a critical review regarding their treatment of development, especially regional, rural and local one. It observes those theories according to different classifications existing in scientific literature, primarily the ascend theory, stagnation theory, balanced economic growth theory; then, short-term and long-term development and growth theories; traditional and endogenous theories; economic growth stages theory emphasized after the WWII; structural changes theory; dependency theory, neo-classic counter-revolution theory and endogenous theory as a new growth theory. The analysis becomes wider with a study on development in regional economy theories and rural studies and it systematizes the classification of those theories according to regional economy academics. Distancing ourselves from any particular division as the most suitable and acceptable one, the theories are treated separately and in an historic context, in order to encircle the time framework which from modern theories, dealing with local level development difficulties, resulted. It asserts The Community-led Rural Development Theory, often referred to as the Community Development Theory, or marked as Bottom-up Partnership Approach. The analysis of development theories asserts that mixed exogenous - endogenous approach to development links the rural/local development to the globalization process mostly due to fast technology changes of the IT and communication sectors.

    2009-07-01

    The integration of socio-economic and environmental objectives is a major challenge in developing strategies for sustainable landscapes. We investigated associations between socio-economic variables, landscape metrics and measures of forest condition in the context of Portugal. The main goals of the study were to 1) investigate relationships between forest conditions and measures of socio-economic development at national and regional scales, 2) test the hypothesis that a systematic variation in forest landscape metrics occurs according to the stage of socio-economic development and, 3) assess the extent to which landscape metrics can inform strategies to enhance forest sustainability. A ranking approach and statistical techniques such as Principal Component Analysis were used to achieve these objectives. Relationships between socio-economic characteristics, landscape metrics and measures of forest condition were only significant in the regional analysis of municipalities in Northern Portugal. Landscape metrics for different tree species displayed significant variations across socio-economic groups of municipalities and these differences were consistent with changes in characteristics suggested by the forest transition model. The use of metrics also helped inform place-specific strategies to improve forest management, though it was also apparent that further work was required to better incorporate differences in forest functions into sustainability planning.

    2016-04-11

    An economic crisis can widen health inequalities between individuals. The aim of this paper is to explore differences in the effect of socioeconomic characteristics on Spaniards' self-assessed health status, depending on the Spanish economic situation. Data from the 2006-2007 and 2011-2012 National Health Surveys were used and binary logit and probit models were estimated to approximate the effects of socioeconomic characteristics on the likelihood to report good health. The difference between high and low education levels leads to differences in the likelihood to report good health of 16.00-16.25 and 18.15-18.22 percentage points in 2006-07 and 2011-12, respectively. In these two periods, the difference between employees and unemployed is 5.24-5.40 and 4.60-4.90 percentage points, respectively. Additionally, the difference between people who live in households with better socioeconomic conditions and those who are in worse situation reaches 5.37-5.46 and 3.63-3.74 percentage points for the same periods, respectively. The magnitude of the contribution of socioeconomic characteristics to health inequalities changes with the economic cycle; but this effect is different depending on the socioeconomic characteristics indicator that is being measured. In recessive periods, health inequalities due to education level increase, but those linked to individual professional status and household living conditions are attenuated. When the joint effects of individuals' characteristics are considered, the economic crisis brings about a slight increase in the inequalities in the probability of reporting good health between the two extreme profiles of individuals. The design of public policies aimed at preventing any worsening of health inequalities during recession periods should take into account these differential effects of socioeconomic characteristics indicators on health inequalities.

    Collins, Alan R.; Hansen, Evan; Hendryx, Michael

    2012-01-01

    Two energy development scenarios were compared for the Coal River Mountain in Raleigh County, West Virginia: (1) mountaintop mining (MTM) of coal, and (2) wind energy plus underground mining of coal. Economic impact computations over the life of each energy development scenario were made on a county basis for output of goods and services, the number of jobs created, and local earnings. Externality costs were assigned monetary values for coal mining and subtracted from earnings. Premature mortality within the general population due to additional coal mining accounted for 96% of these external cost computations. The results showed that economic output over the life of each scenario was twice as high for MTM mining as wind energy plus underground coal mining. Over the short term, employment and earnings were higher for MTM mining, but towards the end of the scenario, cumulative employment and earnings became higher under scenario (2). When local externality costs were subtracted from local earnings, MTM coal production had an overall negative net social impact on the citizens of Raleigh County. The external costs of MTM coal production provide an explanation of the existence of a “resource curse” and the conflicting results of output versus income provide insights into why coal-producing counties are underdeveloped. - Highlights: ► Mountaintop mining (MTM) was compared to wind plus underground mining. ► Economic output was twice as high for MTM. ► Employment and earnings were cumulatively higher for wind energy. ► Including local externality costs, MTM had an overall negative net social impact. ► Results provide insights into why coal-producing counties are underdeveloped.

    Full Text Available Although the regional differences of rural economic development can be easily determined, a challenging problem for research studies regarding rural economic development has been the inter-relatedness between different areas, and this challenge has been noted remarkably little in research data to date. As an empirical investigation, this study analyzes the spatio-temporal characteristics of rural economic development from a period beginning in 1978 to the year 2012, in the eastern coastal region of China. In order to determine the special differentiation characteristics of rural economic development, three indexes, namely the Gini coefficient (G, Tsui–Wang index (TW and Theil index (T, were employed. To explore the inter-relatedness among the different areas, we selected a spatial autocorrelation model. The results indicated that, to a large extent, rural economic development from 1978 to 2012 in the eastern coastal region of China was greatly influenced, and the per capita annual net income changed significantly, due to the process of rapid urbanization and industrialization. Generally speaking, the annual net income constantly increased, from 87.7 USD in 1978 to 1628.1 USD in 2012. However, the calculation results indicated that the per capita income gap in the same province decreased, while the gap between the provinces presented an aggregate trend. The regional polarization widened continuously. It was also found that the spatial positive autocorrelation for the regional economy was significant, with a waving and ascending trend, and the neighbor effect of regional economic growth was continuously strengthened. Qualitative analysis of the driving mechanism was applied, and it was determined that there are three primary factors affecting the development of the rural regions, namely resource endowments, economic location and policies.

    Full Text Available Malnutrition and lack of economic sustainability are major problems in developing countries. This study was conducted to evaluate and compare the nutrients‘ contents of three locally grown nuts in Nigeria (local groundnut, Kampala groundnut and breadnut and highlight their health and economic potentials. Proximate analysis, chemical properties, minerals and fatty acids composition of the nuts were determined. The highest protein, crude fibre and carbohydrate contents were found in Kampala groundnut, local groundnut and breadnut respectively. Their sodium-potassium ratios were all less than 1.0 and their oils have mainly unsaturated fatty acids. Their acid values ranged between (2.41–6.34 mgKOH/g while the iodine values were between 36.0 and 93.0 I2 g/100 g. Analysis of the nuts and their oils indicated that they could help in solving malnutrition problem and also boost nations’ economy. Encouraging their large scale production can enhance adequate nutrition and sustain industrial growth in developing countries. Keywords: Nutrition, Food analysis, Food science

    2016-11-01

    Full Text Available The aim of this study is to demonstrate, in the light of new technologies, the importance of the “long tail” of events for the development of local communities from the economic and tourism standpoint. From the management perspective, an event represents a relevant touristic driver, especially when oriented to small communities. The methodology used, albeit referring to the positive method, incorporates the concept of Chris Anderson’s “long tail” and recent conceptualizations of the Viable Systems Approach. Thus, it refers to literature review method and theory development. Findings of this study emphasize a new perspective of creating value for the development of local communities, based on the evolution of the concept of event (from the mass event to the mass of events. The existing literature on the subject has generally deepened the organizational implications arising from the standardization of events rather than those of customization. Therefore, referring to the originality and value of the present research, it considers the pure customization, which provides even a custom design of the event, a decisive factor for the economic and touristic development of local communities. The study presents also practical implications related with the possibility, thanks to new technologies, to convey to the user/citizen an event that is differentiated and personalized.

    The coastal area is absolutely essential for the purposes of resident, recreation, tourism, fisheries and agriculture as a source of socio-economic development of local community. Some of the activities will affect the coastline changes. Coastline changes may occur due to two main factors include natural factors and also by the factor of human activities in coastal areas. Sea level rise, erosion and sedimentation are among the factors that can contribute to the changes in the coastline naturally, while the reclamation and development in coastal areas are factors of coastline changes due to human activities. Resident area and all activities in coastal areas will provide economic resources to the residents of coastal areas. However, coastline changes occur in the coastal areas will affect socio-economic for local community. A significant effect can be seen through destruction of infrastructure, loss of land, and destroy of crops. Batu Pahat is an area with significant changes of coastline. The changes of coastline from 1985 to 2013 can be determined by using topographical maps in 1985 and satellite images where the changes images are taken in 2011 and 2013 respectively. To identify the changes of risk areas, Coastal Vulnerability Index (CVI) is used to indicate vulnerability for coastal areas. This change indirectly affects the source of income in their agricultural cash crops such as oil palm and coconut. Their crops destroyed and reduced due to impact of changes in the coastline. Identification of risk coastal areas needs to be done in order for the society and local authorities to be prepared for coastline changes.

  11. The impact of sex ratio and economic status on local birth rates.

    Science.gov (United States)

    Chipman, A; Morrison, E

    2013-04-23

    Human mating and reproductive behaviour can vary depending on various mechanisms, including the local sex ratio. Previous research shows that as sex ratios become female-biased, women from economically deprived areas are less likely to delay reproductive opportunities to wait for a high-investing mate but instead begin their reproductive careers sooner. Here, we show that the local sex ratio also has an impact on female fertility schedules. At young ages, a female-biased ratio is associated with higher birth rates in the poorest areas, whereas the opposite is true for the richest areas. At older ages, a female-biased ratio is associated with higher birth rates in the richest, but not the poorest areas. These patterns suggest that female-female competition encourages poorer women to adopt a fast life-history strategy and give birth early, and richer women to adopt a slow life-history strategy and delay reproduction.

    Giovanni Quaranta

    2016-07-01

    Full Text Available The role of tourism in rural areas is pivotal for the integration and valorization of territorial resources and it is strengthened by the capacity to promote local community participation in processes of development. The paper addresses the issue by presenting and discussing a case study of a rural area of southern Italy where a territorial network for the development of local tourism has been set up. The innovative initiative aimed, firstly, to facilitate a closer connection between production and consumption by reducing transaction costs and, secondly, to connect local production with quality conscious consumers looking for traditional products. The network project also aimed to create conditions conducive to increasing the competitiveness of the local production chain and tourism sector. The case study shows how the challenge for many rural territories lies in increasing levels of trust and rebuilding social capital as a precondition of developing the tourism sector and fostering socio-economic development as a whole. Traditional institutions, as well as hybrid institutions, with the support of research organizations, can play a key role.

    Full Text Available This paper considers the role of the public library as a community hub, engagement space, and entrepreneurial incubator in the context of the city, city governance, and local government planning. It considers this role from the perspective of library experts and their future visions for libraries in a networked knowledge economy. Public libraries (often operated by or on behalf of local governments potentially play a pivotal role for local governments in positioning communities within the global digital network. Fourteen qualitative interviews with library experts informed the study which investigates how the relationship between digital technology and the physical library space can potentially support the community to develop innovative, collaborative environments for transitioning to a digital future. The study found that libraries can capitalise on their position as community hubs for two purposes: first, to build vibrant community networks and forge economic links across urban localities; and second, to cross the digital divide and act as places of innovation and lifelong learning. Libraries provide a specific combination of community and technology spaces and have significant tangible connection points in the digital age. The paper further discusses the potential benefits for libraries in using ICT networks and infrastructure, such as the National Broadband Network in Australia. These networks could facilitate greater use of library assets and community knowledge, which, in turn, could assist knowledge economies and regional prosperity.

    The pricing of cosmetic surgery procedures has long been thought to coincide with laws of basic economics, including the model of supply and demand. However, the highly variable prices of these procedures indicate that additional economic contributors are probable. The authors sought to reassess the fit of cosmetic surgery costs to the model of supply and demand and to determine the driving forces behind the pricing of cosmetic surgery procedures. Ten plastic surgery practices were randomly selected from each of 15 US cities of various population sizes. Average prices of breast augmentation, mastopexy, abdominoplasty, blepharoplasty, and rhytidectomy in each city were compared with economic and demographic statistics. The average price of cosmetic surgery procedures correlated substantially with population size (r = 0.767), cost-of-living index (r = 0.784), cost to own real estate (r = 0.714), and cost to rent real estate (r = 0.695) across the 15 US cities. Cosmetic surgery pricing also was found to correlate (albeit weakly) with household income (r = 0.436) and per capita income (r = 0.576). Virtually no correlations existed between pricing and the density of plastic surgeons (r = 0.185) or the average age of residents (r = 0.076). Results of this study demonstrate a correlation between costs of cosmetic surgery procedures and local economic factors. Cosmetic surgery pricing cannot be completely explained by the supply-and-demand model because no association was found between procedure cost and the density of plastic surgeons. © 2015 The American Society for Aesthetic Plastic Surgery, Inc.

    Highlights: • Global environmental protection of using alternative fuel. • Economic aspects of palm oil biodiesel in Malaysia. • Tribological characteristics of palm oil biodiesel in engine components. • Engine performance and emission of palm oil biodiesel. • Effect of temperature on density and kinematic viscosity for various biodiesel. - Abstract: The high cost of energy supplies and the growing concern over the dependency on fossil fuels have impelled many countries to search for renewable and alternative energy sources. The extensive use of fossil fuels for transportation and power generation all over the world have caused the supply of fossil fuels to continuously decrease and have aggravated environmental pollution. Searching for alternative fuels has become imperative to reduce pollution and address the problems on fossil fuels. Vegetable oil fuels, such as palm oil biodiesel, serve as alternative forms of energy and are currently being studied, particularly as a diesel fuel substitute. The purpose of this study is to review the potential of palm oil as an energy source and alternative diesel fuel in terms of its performance, environmental impact, wear characteristics, and economic considerations. Compared with other vegetable oils, palm oil is a relatively sustainable, environment-friendly, less expensive, and economically beneficial potential source of energy. Palm oil plantation and production is a major industry in Malaysia, contributing to the economic growth and development of the country. The properties of palm oil biodiesel, namely, high oxidation stability, good cold properties, cetane number, and higher viscosity, makes it a suitable diesel substitute. Compared with other vegetable oils and petroleum diesel fuels, palm oil is associated with better engine performance, higher specific fuel consumption, and shorter ignition delay. Use of palm oil also reduces exhaust emission of hydrocarbon, carbon monoxide, carbon dioxide, and smoke, but

    Full Text Available The aim of the research was to learn from a survey about the production and economic characteristics of sheep production as well as economic position and developmental orientation of sheep breeders on the island of Pag. Data on production and economic characteristics of sheep production on the island of Pag were collected from a survey and processed through relevant descriptive statistics methods. The respondents have on average 47 breeding sheep, 2 rams and 9 sheep intended for flock renewal rate (not older than one year; which means an average flock has 58 sheep. The average total income from sheep production in 2009 was 72,460.10 HRK. The average total production costs in 2009 were 13,260.10 HRK, including the costs of fodder and veterinary services. All farms achieved positive financial results of 59,199.90 HRK in average. As many as three quarters of respondents indicated profitability of sheep production as the main motivation to engage in sheep production; very few indicated that heritage and inability to do other jobs were the main motivation. Important limiting factors for future development of sheep breeding on the island of Pag in most farms are lack of potential heirs and high average age of farm holders. Regarding the effects of joining the European Union, half the breeders intend to improve their production and harmonise it with the EU requirements and standards; one quarter of them intend to keep the existing production capacity; and another quarter intend to quit with production.

    Several methods to describe the electron-positron (e-p) correlation effects are used in calculations of positron annihilation characteristics in solids. The weighted density approximation (WDA), giving rise to the non-local, state-selective e-p correlation functions, is applied to calculate positron annihilation rates and e-p momentum densities in a variety of metals and silicon. The WDA results are compared to the results of other methods such as the independent particle model, local density approximation, generalised gradient approximation, and also to experiments. The importance of non-locality and state-dependence of the e-p correlation functions is discussed. (orig.)

    Full Text Available This paper allocates complete characteristics of indicators of economic development of subjects of the Russian Federation. Their system representation has appeared more informative, than system of simple social and economic indexes as allows reflecting variety of communications between them, providing preserving and development of researched objects. It is established that at deterioration of state of the economy of regions of their structure change the role in formation of base indicators. At the first stage it is expressed by change of a vector of development with an opposite direction; on the second — in transition from an optimum condition of available structures on periphery; on the third — in the termination of their participation in forming of under laying echelons. At transition of subsystems of social and economic indexes from the first on the second echelon the contribution of the moved potential from structures «resource-product» and «process» for elements of activization increases, for structures «object», on the contrary, decreases, while for final elements the opposite situation is observed. As approaching the top echelon there is a reduction of interaction of base indicators from structures «resource-product» and «process», and on the contrary, growth to structures «object». The conclusion is drawn that successful social and economic activity of regions is determined by synchronous interaction of all allocated structures («resource-product», «process» and «object». Use of the offered algorithm on the basis of complete characteristics allows not only to find out problem regions, but also shows possibility of management on the basis of revealed statistical regularities their condition by forming of optimum mutual relations between the allocated subsystems and, finally, creation of the big possibilities for realization of the having potential

    2013-01-01

    In recent years, engineering oriented work, rather than basic research and development (R&D), has led to significant progress in improving the economics of innovative fast reactors and associated fuel cycle facilities, while maintaining and even enhancing the safety features of these systems. Optimization of plant size and layout, more compact designs, reduction of the amount of plant materials and the building volumes, higher operating temperatures to attain higher generating efficiencies, improvement of load factor, extended core lifetimes, high fuel burnup, etc. are good examples of achievements to date that have improved the economics of fast neutron systems. The IAEA, through its Technical Working Group on Fast Reactors (TWG-FR) and Technical Working Group on Nuclear Fuel Cycle Options and Spent Fuel Management (TWG-NFCO), devotes many of its initiatives to encouraging technical cooperation and promoting common research and technology development projects among Member States with fast reactor and advanced fuel cycle development programmes, with the general aim of catalysing and accelerating technology advances in these fields. In particular the theme of fast reactor deployment, scenarios and economics has been largely debated during the recent IAEA International Conference on Fast Reactors and Related Fuel Cycles: Safe Technologies and Sustainable Scenarios, held in Paris in March 2013. Several papers presented at this conference discussed the economics of fast reactors from different national and regional perspectives, including business cases, investment scenarios, funding mechanisms and design options that offer significant capital and energy production cost reductions. This Technical Meeting on Fast Reactors and Related Fuel Cycle Facilities with Improved Economic Characteristics addresses Member States’ expressed need for information exchange in the field, with the aim of identifying the main open issues and launching possible initiatives to help and

    This research aims to gain an understanding of local socio-environmental characteristics surrounding the Ningyo-Toge Environmental Engineering Center, from the viewpoint of bidirectional information sharing. In order to clarify the relevant issues, we analyzed publicly available information over the past 20 years. We also conducted an internet survey to assess risk perceptions etc. and feelings toward local enterprises, of residents in the surrounding localities and the general public. Expectations for economic benefits of the facilities began to fade in mid 1980s while negative aspects drew increasing attention. Local assemblies disputed over reliability, not technical safety. In Okayama prefecture there found a strong sense of avoidance toward radioactive waste disposal, the background of their refusal of carrying-in of waste rock from Togo-cho Shimane prefecture. A majority of local residents see nuclear facilities as highly dangerous. National newspapers, NHK, professional researchers were identified as reliable sources of information regarding atomic energy and radioactively, indicating the effectiveness of information dissemination through them. Though residents in the surrounding localities are aware of economic benefits of nuclear facilities, a majority of them would refuse the siting of a new one. Meanwhile, revitalization of local communities was found to be in need, in which local enterprises were expected to participate. (author)

    Using a rich dataset that links the Census Bureau's Survey of Income and Program Participation calendar-year 2004 file with Social Security benefit records, this article provides a portrait of the sociodemographic and economic characteristics of Social Security child beneficiaries. We find that the incidence ofbenefit receipt in the child population differs substantially across individual and family-level characteristics. Average benefit amounts also vary across subgroups and benefit types. The findings provide a better understanding of the importance of Social Security to families with beneficiary children. Social Security is a major source of family income for many child beneficiaries, particularly among those with low income or family heads with lower education and labor earnings.

    The report deals with the external conditions for local power production, suggested as a production close to or at the end consumer. The political, legal and economical frame conditions for such production including rating are discussed. The report shall together with a technical report regarding appropriate technologies for such production (A5712), serve as a basis for case studies and monitors later in the project. Through the case studies it will be uncovered how the external conditions are functioning which will make foundations for recommendations concerning possible alterations in the conditions in order to make the local power production more profitable. In the discussion on the political and legal external conditions the system of today is studied. From the political area the general development is described and a short analysis is made of what to expect from case handling procedures, and some challenges are pointed out At present there is a simplified handling of cases of minor and smaller power plants. In order to obtain a more realistic construction of such plants the requirements of license handling may need sharpening. The tariffing of energy deliverance is studied. The regulations for tariffing and income regulation in the distribution network is mainly designed with the consumer and the central power production in mind. A study is made of how the regulations work, to what extent precessions and additional rules are needed and to what extent alterations in the regulations are needed in order to incorporate the local power production in a rational way. While a local power producer at best, will want a price for power which is sold at the power market of the size of 20 oere/kWh, the power will increase in value further down in the voltage level. At the 230 V level the power price will be of the size of 60 oere/kWh all expenses included and the network rent (during normal precipitation conditions). Therefore the production for own consumption will be met

    The role of discrete localized states on the current-voltage characteristics of metal-semiconductor contact is examined. It is seen that, because of these localized states, the logarithmic current vs voltage characteristics become nonlinear. Such nonlinearity is found sensitive to the temperature, and the energy and density of the localized states. The predicted temperature dependence of barrier height and the current-voltage characteristics are in agreement with the experimental results of Aboelfotoh [ Phys. Rev. B39, 5070 (1989)].

    Full Text Available This study aims to research differences in socio-demographic characteristics of foreign tourists in consumption of local food in the city centres Belgrade and Novi Sad, Republic of Serbia. The research was conducted on a sample of 673 respondents. The results of this study point out the importance of socio-demographic variables in research of local gastronomy as a significant component of tourism product. The research included the determining of the impact of the city the tourists stayed at. The differences were examined via two-factor ANOVA analysis of variance. The obtained results indicate that there are differences between age groups, in the level of education, monthly income and countries that foreign tourists come from, whereas there is no difference between genders in relation to the perception of local gastronomy. At the same time, the findings indicate that there are no differences in the perception of local gastronomy between the cities of Novi Sad and Belgrade. The results confirm previous studies and point out the significance of socio-demographic characteristics of foreign tourists in their perception of local gastronomy and adapting it to the visitors, regardless of the city they visited.

    Full Text Available Castration is a controversial practice in swine production because in some countries is still performed without anaesthesia, and therefore causes intense suffering and stress to animals. This study investigated the effect of pre-surgical administration of local anaesthesia (LA on the growth performance of piglets until the end of the growth phase (102 days. Piglets aged 3 to 5 days were selected in pairs of similar weights and same age. They were originated from 22 litters. The groups were randomly assigned to one of two treatments. Castration was performed with (LA; n = 45 or without (NLA; n = 45 intra-testicular administration of 0.5 mL of 2% lidocaine plus adrenaline per testicle, administered by an automatic repeating vaccinator. Castration was performed 10 min later. Average daily weight gain and economic impact were evaluated between the intervals before castration until 21 (weaning phase, before castration until 60 (end of the initial nursery phase and before castration until 102 (growth phase days of age. Average daily weight gain data were analyzed by comparing the average daily weight gain between the weaning phase, 60 and 102 days of age versus the initial weight (pre-castration. At the end of the growing phase, animals treated with LA showed greater weight gain than animals castrated without anaesthesia. LA also showed improved cost:benefit ratio and theore might provide greater economic benefit under the conditions used in this study. Our findings have proved that castration with LA improves long-term weight gain of piglets.

    2003-02-01

    The Feed System Innovation for Gasification of Locally Economical Alternative Fuels (FIGLEAF) project was conducted by the Energy & Environmental Research Center and Gasification Engineering Corporation of Houston, Texas (a subsidiary of Global Energy Inc., Cincinnati, Ohio), with 80% cofunding from the U.S. Department of Energy (DOE). The goal of the project was to identify and evaluate low-value fuels that could serve as alternative feedstocks and to develop a feed system to facilitate their use in integrated gasification combined-cycle and gasification coproduction facilities. The long-term goal, to be accomplished in a subsequent project, is to install a feed system for the selected fuel(s) at Global Energy's commercial-scale 262-MW Wabash River Coal Gasification Facility in West Terre Haute, Indiana. The feasibility study undertaken for the project consisted of identifying and evaluating the economic feasibility of potential fuel sources, developing a feed system design capable of providing a fuel at 400 psig to the second stage of the E-Gas (Destec) gasifier to be cogasified with coal, performing bench- and pilot-scale testing to verify concepts and clarify decision-based options, reviewing information on high-pressure feed system designs, and determining the economics of cofeeding alternative feedstocks with the conceptual feed system design. A preliminary assessment of feedstock availability within Indiana and Illinois was conducted. Feedstocks evaluated included those with potential tipping fees to offset processing cost: sewage sludge, municipal solid waste, used railroad ties, urban wood waste (UWW), and used tires/tire-derived fuel. Agricultural residues and dedicated energy crop fuels were not considered since they would have a net positive cost to the plant. Based on the feedstock assessment, sewage sludge was selected as the primary feedstock for consideration at the Wabash River Plant. Because of the limited waste heat available for drying and

    Full Text Available Brazil remains the country in the Americas with the highest prevalence of schistosomiasis. A combination of control efforts and development, however, has sharply reduced its intensity and distribution. The acquisition of specific schistosome populations may be dependent on host characteristics such as sex, age, geography, work, habits and culture. How these and other host characteristics align with parasite subpopulations may guide approaches to improve control.A cohort of more than 90% of the residents in two rural communities in Brazil participated in an epidemiologic survey of demographic, socio-economic and behavioral characteristics. The variables sex, age, intensity of infection, socio-economic index, % lifetime spent on site, previous infection, and trips outside the district were used to group parasites infecting individuals. Schistosoma mansoni infection status was determined by examination of stools submitted on 3 different days. The aggregate of eggs collected from the whole stool was used to determine degree of population differentiation from allele frequencies for 15 microsatellites.Infection prevalence was 41% for these communities, and the epidemiologic characteristics were similar to many of the endemic areas of Brazil and the world. Parasite population structuring was observed between the two communities (Jost's D 0.046, CI95% 0.042-0.051, although separated by only 8 km and connected by a highway. No structuring was observed when infected individuals were stratified by host's biologic, demographic or epidemiologic characteristics. Those most heavily infected best reflected the communities' overall parasite diversity. The lack of differentiation within villages suggests that individuals are likely to get infected at the same sites or that the same parasite multilocus genotypes can be found at most sites. The geographic structuring between villages and the lack of structuring by age of the host further supports the impression of

    Full Text Available La situación por la que atraviesa la economía internacional, las altas tasas de desempleo, el creciente número de cierres de empresas, la despoblación de algunas zonas y la masificación de otras, son las claves que caracterizan el mercado de trabajo español, en particular y la sociedad, en general. A principios de los años ochenta, empieza a oirse en ámbitos científicos, la idea de una descentralización a ultranza; sobre todo teniendo en cuenta, y hablando del entorno que nos ocupa, que en España se entra en el período democrático y por tanto, en "la era de las autonomías". Esta descentralización de la España democrática se caracteriza por la fuerte intervención del Estado en el desarrollo de las re­giones. Partían del Estado central las primeras iniciativas, con el fin primordial de borrar las desigualdades regionales, y más concretamente, el crecimiento de las áreas rurales retrasadas en contraposición a las zonas urbanas. La ineficacia derivada de esta etapa estuvo provocada, directa o indirectamen­te, por el reducido conocimiento de la Administración central de los numerosos recursos por explotar en nuestras comunidad es locales, que facilitarían el crecimiento económico y elevarían el nivel de vida, objetivos básicos en el fortalecimiento de nuestras economías endógenas. Esto nos induce a centrarnos en el estudio de la Teoría del Desarrollo Local como instrumento formulador de políticas convergentes hacia el desarrollo global y macroeconómico que gozan de autonomía para los intereses concretos de cada área. Por tanto, el principal objetivo en este trabajo de investigación ha sido iniciar un estudio más profundo de un tema tan actual, por su mucha utilización en la década en que vivimos y su reducido análisis por parte de los economistas, como puede ser la planificación estratégica y su implantación en un territorio concreto.

    Full Text Available There is limited information on intra-annual plasticity of secondary tissues of tree species growing under different environmental conditions. To increase the knowledge about the plasticity of secondary growth, which allows trees to adapt to specific local climatic regimes, we examined climate–radial growth relationships of Norway spruce (Picea abies (L. H. Karst. from three contrasting locations in the temperate climatic zone by analyzing tree-ring widths for the period 1932–2010, and cell characteristics in xylem and phloem increments formed in the years 2009–2011. Variation in the structure of xylem and phloem increments clearly shows that plasticity in seasonal dynamics of cambial cell production and cell differentiation exists on xylem and phloem sides. Anatomical characteristics of xylem and phloem cells are predominantly site-specific characteristics, because they varied among sites but were fairly uniform among years in trees from the same site. Xylem and phloem tissues formed in the first part of the growing season seemed to be more stable in structure, indicating their priority over latewood and late phloem for tree performance. Long-term climate and radial growth analyses revealed that growth was in general less dependent on precipitation than on temperature; however, growth sensitivity to local conditions differed among the sites. Only partial dependence of radial growth of spruce on climatic factors on the selected sites confirms its strategy to adapt the structure of wood and phloem increments to function optimally in local conditions.

    The purpose of this controlled trial was to investigate the effects of a single local cryotherapy session on the recovery characteristics over a period of 72 hours. Twenty-two young and healthy female (n=17; mean age: 21.9±1.1 years) and male (n=5;mean age: 25.4±2.8 years) adults participated in this study. Following an exhaustive jump protocol (3×30 countermovement jumps), half of the participants received either a single local cryotherapy application (+8°C) or a single local thermoneutral application (+32°C) of 20-minute duration using two thigh cuffs. Subjective measures of recovery (delayed-onset muscle soreness and ratings of perceived exertion) and objective measures of recovery (vertical jump performance and peak power output) were assessed immediately following the postexercise applications (0 hours) and at 24 hours, 48 hours, and 72 hours after the jump protocol. Local cryotherapy failed to significantly affect any subjective recovery variable during the 72-hour recovery period (P>0.05). After 72 hours, the ratings of perceived exertion were significantly lower in the thermoneutral group compared to that in the cryotherapy group (P=0.002). No significant differences were observed between the cryotherapy and the thermoneutral groups with respect to any of the objective recovery variables. In this experimental study, a 20-minute cryotherapy cuff application failed to demonstrate a positive effect on any objective measures of recovery. The effects of local thermoneutral application on subjective recovery characteristics were superior when compared to the effects of local cryotherapy application at 72 hours postapplication.

    There is mounting concern over increasing rates of physical inactivity and overweight/obesity among children and adult in Canada. There is a clear link between the amount of walking a person does and his or her health. The purpose of this paper is to assess the health factors, socio-economic characteristics and urban-regional variations of walking to work among adults in Canada. Data is drawn from two cycles of the Canadian Community Health Survey: 2001 and 2005. The study population is divided into three groups: non-walkers, lower-duration walkers and high-duration walkers. Logistic regression modeling tests the association between levels of walking and health related outcomes (diabetes, high blood pressure, stress, BMI, physical activity), socio-economic characteristics (sex, age, income, education) and place of residence (selected Census Metropolitan Areas). In 2005, the presence of diabetes and high blood pressure was not associated with any form of walking. Adults within the normal weight range were more likely to be high-duration walkers. Females and younger people were more likely to be lower-duration walkers but less likely to be high-duration walkers. There was a strong association between SES (particularly relative disadvantage) and walking to work. In both 2001 and 2005, the conditions influencing walking to work were especially prevalent in Canada's largest city, Toronto, as well as in several small to medium sized urban areas including Halifax, Kingston, Hamilton, Regina, Calgary and Victoria. A number of strategies can be followed to increase levels of walking in Canada. It is clear that for many people walking to work is not possible. However, strategies can be developed to encourage adults to incorporate walking into their daily work and commuting routines. These include mass transit walking and workplace walking programs.

    Gambling behavior is not a unique behavior. There are certain differences in behavior, gambling habits, gambling beliefs, and their reflection in psychosocial life. We have compared three groups of adult male gamblers—sports gamblers (n = 41), machine gamblers (n = 36), and poker gamblers (n = 35)—in regard to measures of personal status and legal-social characteristics. We found no difference between groups in terms of the length of gambling behavior, personal status, or age. We found no legal difference between groups in terms of the number of court cases for debt, stealing, or family court cases. In terms of economic circumstances, sports gamblers suffered more losses than the other groups (p < 0.0001). There were higher rates of bankruptcy among sports gamblers compared with machine gamblers (p < 0.01). Sports gamblers were more likely to borrow money from the black market compared with the other groups (p < 0.01). In terms of mental health, sports and machine gamblers had more suicidal thoughts and gestures than poker gamblers (p < 0.05), whereas the rate of suicide attempts was higher in machine gamblers compared with poker players (p < 0.05). Our results indicated higher vulnerability in sports gamblers in terms of economic problems compared with the other groups, whereas machine gamblers had vulnerability to suicidal thoughts and suicidal attempts compared with poker gamblers.

    Full Text Available Abstract Background Gallstones have been regarded as one of the most expensive diseases in Gastroenterology, posing a great economic burden on developing nations. The majority of Pakistani people live in rural areas where healthcare facilities are not available or are very primitive. We aim to assess the characteristics among cholelithiasis patients from rural Karachi so that a prevention campaign can be launched in rural underprivileged settings to reduce the economic burden of this preventable disease. Method A total of 410 patients were included in the study after giving verbal consent as well as written consent. Variables such as age, weight, height, body mass index (BMI, blood pressure, waist circumference, number of children, monthly family income, number of siblings, and number of family members, were considered in this questionnaire.

    Full Text Available Complying with the carrying capacity of local and global ecosystems is a prerequisite to ensure environmental sustainability. Based on the example of Swiss mountain dairy farms, the goal of our research was firstly to investigate the relationship between farm global and local environmental performance. Secondly, we aimed to analyse the relationship between farm environmental and economic performance. The analysis relied on a sample of 56 Swiss alpine dairy farms. For each farm, the cradle-to-farm-gate life cycle assessment was calculated, and the quantified environmental impacts were decomposed into their on- and off-farm parts. We measured global environmental performance as the digestible energy produced by the farm per unit of global environmental impact generated from cradle-to-farm-gate. We assessed local environmental performance by dividing farm-usable agricultural area by on-farm environmental impact generation. Farm economic performance was measured by work income per family work unit, return on equity and output/input ratio. Spearman’s correlation analysis revealed no significant relationship, trade-offs or synergies between global and local environmental performance indicators. Interestingly, trade-offs were observed far more frequently than synergies. Furthermore, we found synergies between global environmental and economic performance and mostly no significant relationship between local environmental and economic performance. The observed trade-offs between global and local environmental performance mean that, for several environmental issues, any improvement in global environmental performance will result in deterioration of local environmental performance and vice versa. This finding calls for systematic consideration of both dimensions when carrying out farm environmental performance assessments.

    Purpose: With the increasing use of conformal radiation therapy methods for non-small cell lung cancer (NSCLC), it is necessary to accurately determine respiratory-induced tumor motion. The purpose of this study is to analyze and compare the motion characteristics of early and locally advanced stage NSCLC tumors in a large population and correlate tumor motion with position, volume, and diaphragm motion. Methods and materials: A total of 191 (94 early stage, 97 locally advanced) non-small cell lung tumors were analyzed for this study. Each patient received a four-dimensional CT scan prior to receiving radiation treatment. A soft-tissue-based rigid registration algorithm was used to track the tumor motion. Tumor volumes were determined based on the gross tumor volume delineated by physicians in the end of expiration phase. Tumor motion characteristics were correlated with their standardized tumor locations, lobe location, and clinical staging. Diaphragm motion was calculated by subtracting the diaphragm location between the expiration and the inspiration phases. Results: Median, max, and 95th percentile of tumor motion for early stage tumors were 5.9 mm, 31.0 mm, and 20.0 mm, which were 1.2 mm, 12 mm, and 7 mm more than those in locally advanced NSCLC, respectively. The range of motion at 95th percentile is more than 50% larger in early stage lung cancer group than in the locally advanced lung cancer group. Early stage tumors in the lower lobe showed the largest motion with a median motion of 9.2 mm, while upper/mid-lobe tumors exhibited a median motion of 3.3 mm. Tumor volumes were not correlated with motion. Conclusion: The range of tumor motion differs depending on tumor location and staging of NSCLC. Early stage tumors are more mobile than locally advanced stage NSCLC. These factors should be considered for general motion management strategies when 4D simulation is not performed on individual basis.

    Full Text Available Modern society is characterised not only by a fascination with scientific technology as a means of solving all problems, especially those that stand in the way of material progress (technicism, but also by an obsessive interest in everything that has to do with money (economism or mammonism. The article discusses the relationship between technicism and economism, on the basis of their relationship to utilitarian thinking: the quest for the greatest happiness for the greatest number of people. Recent major studies of neo-liberalism (seen as an intensification of utilitarianism by Laval and Dardot are used as reference to the development of utilitarianism. It is suggested that the western view of the world, as expressed in economism and technicism, with a utilitarian ethics, features three absolutisations: those of theoretical thinking, technology and economics. In a second part, the article draws on the framework of reformational philosophy to suggest an approach that, in principle, is not marred by such absolutisations.

Today there is a number of problems, which doesn't allow housing and utility services to function effectively. The main of them is providing high-quality housing and utility services to the population and system of their objective cost assessment. This problem is solved by means of reforming the housing and utility sphere with the possibility of attracting financial resources from private investors. Housing and Utility of the Russian Federation, the basis of which is the housing stock, has a very high specific weight in fixed assets of all the economy.Thus, Housing and Utility is a typical difficult organizational and economic system possessing characteristic features of openness, nonlinearity and dissipativity. In this re-gard, the reasonable approach to Housing and Utility development assumes the need to account for the principles of systemacity, focus and complexity, and also can be based on the existing in the theory and practice of management methodology by difficult organizational and economic systems.Now Housing and Utility development and financing investment programs of the municipal complex organizations is carried out according to the relevant Federal law, according to which the establishment system of limit indexes of change of tariffs and investment extra charges to tariffs for services of the organizations of a municipal complex. Also, innovative ways of energy efficiency increase and decrease in wear of funds is an attempt of the state to develop effective mechanisms of attracting private funds from investors.

    Patients benefit from receiving cancer treatment closer to home when possible and at high-volume regional centers when specialized care is required. The purpose of this analysis was to estimate the economic impact of retaining more patients in-state for cancer clinical trials and care, which might offset some of the costs of establishing broader cancer trial and treatment networks. Kansas Cancer Registry data were used to estimate the number of patients retained in-state for cancer care following the expansion of local cancer clinical trial options through the Midwest Cancer Alliance based at the University of Kansas Medical Center. The 2014 economic impact of this enhanced local clinical trial network was estimated in four parts: Medical spending was estimated on the basis of National Cancer Institute cost-of-care estimates. Household travel cost savings were estimated as the difference between in-state and out-of-state travel costs. Trial-related grant income was calculated from administrative records. Indirect and induced economic benefits to the state were estimated using an economic impact model. The authors estimated that the enhanced local cancer clinical trial network resulted in approximately $6.9 million in additional economic activity in the state in 2014, or $362,000 per patient retained in-state. This estimate includes $3.6 million in direct spending and $3.3 million in indirect economic activity. The enhanced trial network also resulted in 45 additional jobs. Retaining patients in-state for cancer care and clinical trial participation allows patients to remain closer to home for care and enhances the state economy.

    2013-04-01

    Economically motivated adulteration (EMA) of food, also known as food fraud, is the intentional adulteration of food for financial advantage. A common form of EMA, undeclared substitution with alternative ingredients, is usually a health concern because of allergen labeling requirements. As demonstrated by the nearly 300,000 illnesses in China from melamine adulteration of infant formula, EMA also has the potential to result in serious public health consequences. Furthermore, EMA incidents reveal gaps in quality assurance testing methodologies that could be exploited for intentional harm. In contrast to foodborne disease outbreaks, EMA incidents present a particular challenge to the food industry and regulators because they are deliberate acts that are intended to evade detection. Large-scale EMA incidents have been described in the scientific literature, but smaller incidents have been documented only in media sources. We reviewed journal articles and media reports of EMA since 1980. We identified 137 unique incidents in 11 food categories: fish and seafood (24 incidents), dairy products (15), fruit juices (12), oils and fats (12), grain products (11), honey and other natural sweeteners (10), spices and extracts (8), wine and other alcoholic beverages (7), infant formula (5), plant-based proteins (5), and other food products (28). We identified common characteristics among the incidents that may help us better evaluate and reduce the risk of EMA. These characteristics reflect the ways in which existing regulatory systems or testing methodologies were inadequate for detecting EMA and how novel detection methods and other deterrence strategies can be deployed. Prevention and detection of EMA cannot depend on traditional food safety strategies. Comprehensive food protection, as outlined by the Food Safety Modernization Act, will require innovative methods for detecting EMA and for targeting crucial resources toward the riskiest food products.

    1987-03-01

    A joint Oak Ridge - Roane County citizen task force (TF) evaluated the Department of Energy's (DOE) proposal to site a Monitored Retrievable Storage facility in Tennessee in terms of environmental, transportation, and socioeconomic impacts. The case study examines how the TF used mitigation, compensation and incentives (economic and non-economic) to address the problem of distrust of DOE and to change the net local impact balance from negative to positive. Intensive group interaction during their investigations and development of trust within the TF led to consensus decisions on safety and conditional acceptance. DOE accepted most of the TF conditions after informal negotiations. The siting process was stopped by extensive state-wide opposition resulting in legal challenge by the state and vetoes by the governor and state legislature

    Model of porous media with internal heat source is established. The model uses water as flowing media, and the stainless steel test section is packed with steel spheres in manner of regular triangle, respectively. The armoured resistance wire is inserted inside the steel sphere. On the basis of the experimental model, many parameters of the local heat transfer characteristics including current velocity and wall temperature of steel sphere are measured. The experimental results show that the coefficient of heat transfer scarcely changes with pressure. The coefficient of heat transfer increases with the surface heat flux of steel sphere. When raising the inlet temperature of the cooling water, the coefficient of heat transfer presents the descending trend. In addition, the influence of entrance effect on heat transfer is discovered in the experiment, which is much less than the liquid flow in the light tube. After experiment data are analyzed and processed, the relation model of heat transfer on local heat transfer characteristic of porous media with internal heat source was described with a power-law-equation. The deviations between calculation and experimental values are within ±10%. (authors)

    Here, we discuss the local photovoltaic characteristics of a structured bulk heterojunction, organic photovoltaic devices fabricated with a liquid carbazole, and a fullerene derivative based on analysis by scanning kelvin probe force microscopy (KPFM). Periodic photopolymerization induced by an interference pattern from two laser beams formed surface relief gratings (SRG) in the structured films. The surface potential distribution in the SRGs indicates the formation of donor and acceptor spatial distribution. Under illumination, the surface potential reversibly changed because of the generation of fullerene anions and hole transport from the films to substrates, which indicates that we successfully imaged the local photovoltaic characteristics of the structured photovoltaic devices. Using atomic force microscopy, we confirmed the formation of the SRG because of the material migration to the photopolymerized region of the films, which was induced by light exposure through photomasks. The structuring technique allows for the direct fabrication and the control of donor and acceptor spatial distribution in organic photonic and electronic devices with minimized material consumption. This in situ KPFM technique is indispensable to the fabrication of nanoscale electron donor and electron acceptor spatial distribution in the devices.

    Generally speaking, the creation of tariff systems for energy activities carried out as regulated or public service obligation is becoming professionally challenging. The Croatian Energy Regulatory Agency (CERA) created the methodology of the tariff system for thermal energy activities and passed this tariff system (without tariff element amounts) in May 2006. The background of the tariff system for thermal energy activities (heat generation, heat distribution and heat supply) including a legislative framework relevant for passing the tariff system, terminology, matrix of the tariff models, tariff elements and amounts of tariff entries are analyzed in this paper. Special attention is paid to the economic characteristics of the tariff system, such as the capital asset pricing model (CAPM), which is chosen among several models of the weighted average of cost of capital (WACC). Using the WACC, the regulatory authorities ensure returns to be equal to the opportunity cost of capital. Furthermore, main formulae and procedures for submitting the proposal for changing the amounts of tariff elements are analyzed as well

    Economic and mathematical simulation is promoted by a standard procedure of computations to optimize development of production for the future as the principal method of solution of a problem. However traditional approaches to design of models need refinement which take into account the dynamic nature of a coal mine. First, the characteristics of the elements in subsystems change; second, as time passes the very structure of the system is transformed. Consequently, these processes should be reflected in the simulation in a corresponding manner. In practical terms this is expressed in the formation of files of forecast information used in computations according to a model and also in development of procedures of transformation of the model structure with a change of the structure of the subject mine with time. Let us note that the invariability of the state of the principal elements of the technological scheme of a mine with time is the necessary condition of acceptability of a model of the evolution type which is most common. For working mines the freedom of selecting solutions is considerably less than the analogous one in design.

    Full Text Available Characterizing local chicken types and their mostly rural production systems is prerequisite for designing and implementing development and conservation programs. This study evaluated the management practices of small-scale chicken keepers and the phenotypic and production traits of their chickens in Oman, where conservation programs for local livestock breeds have currently started. Free-range scavenging was the dominant production system, and logistic regression analysis showed that socio-economic factors such as training in poultry keeping, household income, income from farming and gender of chicken owners influenced feeding, housing, and health care practices (p<0.05. A large variation in plumage and shank colors, comb types and other phenotypic traits within and between Omani chicken populations were observed. Male and female body weight differed (p<0.05, being 1.3±0.65 kg and 1.1±0.86 kg respectively. Flock size averaged 22±7.7 birds per household with 4.8 hens per cock. Clutch size was 12.3±2.85 and annual production 64.5±2.85 eggs per hen. Egg hatchability averaged 88±6.0% and annual chicken mortality across all age and sex categories was 16±1.4%. The strong involvement of women in chicken keeping makes them key stakeholders in future development and conservation programs, but the latter should be preceded by a comprehensive study of the genetic diversity of the Omani chicken populations.

    Infection with rubella virus during pregnancy can result in congenital defects and adverse pregnancy outcomes. The risk of rubella infection is greatly determined by the level of rubella antibodies in the serum. A survey of rubella antibody seronegativity rates was conducted in 780 000 women in rural China who were planning a pregnancy, in order to evaluate the herd susceptibility in different age groups and by high, middle, and low GDP per capita regions. In order to evaluate the herd susceptibility to rubella, a nationwide population-based study of rural Chinese women who were planning to have a baby and who were aged 21-49 years was instigated. As a part of the National Free Pre-conception Health Examination Project covering 29 provinces in 2012, a physical check-up program was provided to women who planned to become pregnant within the next 6 months. All medical data were from serological samples tested by ELISA, and the participants' immunity status was categorized based on levels of rubella antibodies. Economic data were also collected to explore the association between herd susceptibility and socioeconomic characteristics in the women of childbearing age. A total 264 306 of 782 293 recruited women preparing for pregnancy tested susceptible to rubella (33.79%). The seronegativity rate in women with a history of vaccination was significantly lower than that in women who had not received the vaccination or did not know their vaccination history (23.76%, 33.70%, and 35.68%, respectively). The seronegativity rates were 26.89%, 37.86%, and 32.61% in high, middle, and low GDP per capita areas, respectively. After stratified analysis and adjusting for other factors by multiple logistic regression, the lower seronegativity rates in women in high GDP per capita regions compared to women in middle and low GDP per capita regions remained in the different age groups and subgroups of immunization history. There is a clear difference in rubella-specific susceptibility

  15. Water and Land Footprints and Economic Productivity as Factors in Local Crop Choice: The Case of Silk in Malawi

    2017-10-01

    Full Text Available In deciding what crops to grow, farmers will look at, among other things, the economically most productive use of the water and land resources that they have access to. However, optimizing water and land use at the farm level may result in total water and land footprints at the catchment level that are in conflict with sustainable resource use. This study explores how data on water and land footprints, and on economic water and land productivity can inform micro-level decision making of crop choice, in the macro-level context of sustainable resource use. For a proposed sericulture project in Malawi, we calculated water and land footprints of silk along its production chain, and economic water and land productivities. We compared these to current cropping practices, and addressed the implications of water consumption at the catchment scale. We found that farmers may prefer irrigated silk production over currently grown rain-fed staple crops, because its economic water and land productivity is higher than that for currently grown crops. However, because the water footprint of irrigated silk is higher, sericulture will increase the pressure on local water resources. Since water consumption in the catchment generally does not exceed the maximum sustainable footprint, sericulture is a viable alternative crop for farmers in the case study area, as long as silk production remains small-scale (~3% of the area at most and does not depress local food markets.

  18. Municipal Local Economic Development and the Multiplier effect: Piloting a Community Enterprise Identification Method in South Africa and Namibia

    Directory of Open Access Journals (Sweden)

    Lucienne Heideman

    2011-12-01

    Full Text Available Local Economic Development (LED is a contested concept in southern Africa, and has become synonymous with delivery of generic job-creation projects, often grant-dependent and unsustainable. Municipal LED has followed this pattern in South Africa since 1994, with little lasting success. Each local economy is unique, and has its own problems and opportunities. The ’Plugging the Leaks’ method recognizes that communities themselves know best how money enters and exits their area. By asking people to analyse their local economy as a 'leaky bucket', the method puts control back in the hands of local people, rather than external experts, and allows them to analyse their own local economy to identify gaps and opportunities for enterprise. By better networking and working collectively to improve their local economy, local communities are able to re-circulate cash internally. This circulation of cash is explained as the local multiplier effect in the workshops. A pilot process of running ‘Plugging the Leaks’ workshops in low income communities in South Africa and Namibia revealed that spending choices in these communities are severely limited in a context where there is no effective welfare state. Therefore, empowerment with this method came from the discovery of collective action and networking, rather than from individual spending choices. Local start-up business tends to be limited to survivalist and copy-cat one-person ventures, and are a last resort when formal employment is absent. In this context collective enterprise offers the necessary empowerment for people to attempt financially sustainable ventures that respond to a gap in the local economy. The pilot project is attempting to show that municipal LED staff can play the role of facilitator for initiating the enterprise-identification process and further mobilise state enterprise support agencies around the locus of LED, without crossing the line between facilitation and implementation

    Characteristics of local parameters of bubbly flow were investigated in rectangular channel (40 mm × 3 mm) under inclined and rolling conditions. Under vertical condition, the distribution type 'wall peak' and 'core peak' are observed, and 'core peak' exists when the liquid superficial velocity is low and the gas superficial velocity is high. Under inclined condition, the peaks of two distribution types get strengthened at the top of the channel, and weakened at the bottom. Under rolling condition, the peaks of two distribution types get strengthened compared with the same angle under inclined condition when the angle is getting larger. The influence from rolling motion gets stronger on the peak of two distribution types when the rolling movement is more violent. (authors)

    Generally, a CHP plant coupled with district heating is considered more efficient than traditional local heating systems from an economic and environmental point of view. This is certainly true for municipal waste CHP plants, but for plants fuelled by natural gas the important developments of the last years regarding both boilers (premixed and modulating burners, condensing boilers, etc.) and mechanical vapour compression and absorption heat pumps can change the traditional view. At the same time also district heating plants improved. Therefore it is worth to analyse the whole matter comparing advantages and disadvantages of the different alternatives, with a wide difference between them. The paper reports on the analysis of major district heating natural gas based technologies (vapour and gas turbines, internal combustion engine, combined cycles); the cost of heat and power produced in these plants is compared to the cost of producing the same quantity of electrical energy by a reference GTCC-Gas Turbine Combined Cycle (actually the most efficient technology for pure electrical production) and the cost of heat production by modern local heating technologies using natural gas as fuel (condensing boilers, electrical, gas engine and absorption heat pumps). Regarding energy efficiency and emissions, modern local heating turns out to be more efficient than district heating for most CHP technologies. However, the same does not happen from an economic point of view, because in Italy natural gas used by cogeneration plants is subjected to a much lower taxation than local heating technologies

    2012-01-01

    Full Text Available We introduce the extension of local polynomial fitting to the linear heteroscedastic regression model. Firstly, the local polynomial fitting is applied to estimate heteroscedastic function, then the coefficients of regression model are obtained by using generalized least squares method. One noteworthy feature of our approach is that we avoid the testing for heteroscedasticity by improving the traditional two-stage method. Due to nonparametric technique of local polynomial estimation, we do not need to know the heteroscedastic function. Therefore, we can improve the estimation precision, when the heteroscedastic function is unknown. Furthermore, we focus on comparison of parameters and reach an optimal fitting. Besides, we verify the asymptotic normality of parameters based on numerical simulations. Finally, this approach is applied to a case of economics, and it indicates that our method is surely effective in finite-sample situations.

    2018-02-01

    Full Text Available This paper presents novel feature descriptors and classification algorithms for the automated scoring of HER2 in Whole Slide Images (WSI of breast cancer histology slides. Since a large amount of processing is involved in analyzing WSI images, the primary design goal has been to keep the computational complexity to the minimum possible level and to use simple, yet robust feature descriptors that can provide accurate classification of the slides. We propose two types of feature descriptors that encode important information about staining patterns and the percentage of staining present in ImmunoHistoChemistry (IHC-stained slides. The first descriptor is called a characteristic curve, which is a smooth non-increasing curve that represents the variation of percentage of staining with saturation levels. The second new descriptor introduced in this paper is a local binary pattern (LBP feature curve, which is also a non-increasing smooth curve that represents the local texture of the staining patterns. Both descriptors show excellent interclass variance and intraclass correlation and are suitable for the design of automatic HER2 classification algorithms. This paper gives the detailed theoretical aspects of the feature descriptors and also provides experimental results and a comparative analysis.

    Investigation on the equilibrium operation regime, its ideal magnetohydrodynamics (MHD) stability and edge localized modes (ELM) characteristics is performed for the China Fusion Engineering Test Reactor (CFETR). The CFETR operation regime study starts with a baseline scenario (R  =  5.7 m, B T  =  5 T) derived from multi-code integrated modeling, with key parameters {{β }N},{{β }T},{{β }p} varied to build a systematic database. These parameters, under profile and pedestal constraints, provide the foundation for the engineering design. The long wavelength low-n global ideal MHD stability of the CFETR baseline scenario, including the wall stabilization effect, is evaluated by GATO. It is found that the low-n core modes are stable with a wall at r/a  =  1.2. An investigation of intermediate wavelength ideal MHD modes (peeling ballooning modes) is also carried out by multi-code benchmarking, including GATO, ELITE, BOUT++ and NIMROD. A good agreement is achieved in predicting edge-localized instabilities. Nonlinear behavior of ELMs for the baseline scenario is simulated using BOUT++. A mix of grassy and type I ELMs is identified. When the size and magnetic field of CFETR are increased (R  =  6.6 m, B T  =  6 T), collisionality correspondingly increases and the instability is expected to shift to grassy ELMs.

    Food insecurity and its most extreme form, hunger, have increased exponentially in the United States since 2006. This essay seeks to contribute to our understanding of hunger by attending to the context of the financial crisis as an organizing frame for understanding local meanings of hunger. Within a broader framework of the culture-centered approach (CCA) that works to identify and develop locally rooted solutions to food insecurity, we describe through locally grounded stories of food insecurity the financial climate where large percentages of U.S. households have been cast into poverty because of the crash of an unregulated economy. These local understandings of hunger in the context of the economy offer entry points for organizing a food-insecure coalition that seeks to address the stigma around food insecurity.

These lands managed by the National Park Service (NPS) serve as recreational destinations for visitors from across the Nation and around the world. On vacations or on day trips, NPS visitors spend time and money in the gateway communities surrounding NPS sites. Spending by NPS visitors generates and supports a considerable amount of economic activity within park gateway economies. The NPS has been measuring and reporting visitor spending and economic effects for the past 25 years. The 2012 analysis marked a major revision to the NPS visitor spending effects analyses, with the development of the Visitor Spending Effects model (VSE model) which replaced the previous Money Generation Model (see Cullinane Thomas et al. (2014) for a description of how the VSE model differs from the previous model). This report provides updated VSE estimates associated with 2014 NPS visitation.

  14. An Economic Assessment of Local Farm Multi-Purpose Surface Water Retention Systems under Future Climate Uncertainty

    Full Text Available Regions dependent on agricultural production are concerned about the uncertainty associated with climate change. Extreme drought and flooding events are predicted to occur with greater frequency, requiring mitigation strategies to reduce their negative impacts. Multi-purpose local farm water retention systems can reduce water stress during drought periods by supporting irrigation. The retention systems’ capture of excess spring runoff and extreme rainfall events also reduces flood potential downstream. Retention systems may also be used for biomass production and nutrient retention. A sub-watershed scale retention system was analysed using a dynamic simulation model to predict the economic advantages in the future. Irrigated crops using water from the downstream reservoir at Pelly’s Lake, Manitoba, Canada, experienced a net decrease in gross margin in the future due to the associated irrigation and reservoir infrastructure costs. However, the multi-purpose benefits of the retention system at Pelly’s Lake of avoided flood damages, nutrient retention, carbon sequestration, and biomass production provide an economic benefit of $25,507.00/hectare of retention system/year. Multi-purpose retention systems under future climate uncertainty provide economic and environmental gains when used to avoid flood damages, for nutrient retention and carbon sequestration, and biomass production. The revenue gained from these functions can support farmers willing to invest in irrigation while providing economic and environmental benefits to the region.

    Full Text Available Understanding human mobility patterns provides knowledge about impacts of a socio-economic transformation in a rapidly urbanizing environment. This study assesses a long-term mobility data which uses a face-to-face questionnaire and GPS logger-based method of data collection for extracting socio-economic impacts from the rapid transformation. Conversion of mobility related information such as travel distance, direction, and time from the questionnaire survey into spatiotemporal information was carried out by developing an algorithm. To illustrate the proposed approach, a case study in Dawei Special Economic Zone, Myanmar was conducted. The results show that the questionnaire-based mobility data can be associated with GPS-based mobility data and diverse mobility patterns are found for different social groups in the stage of urban formation. The results enabled an understanding of the human dynamics in interactions, which can be used for monitoring rural sustainability and its challenges in the future with the background of the accelerated project development in the area.

    Full Text Available One of the sociological features of the current economic crises had been its beginning as a media fact rather than economic reality for ordinary people in Poland. Until the very end of 2008 the offi cial strategy of Polish government was denying of present of any economic crises in Poland: “The Polish economy as well as Polish banking system are used to be healthy and in good conditions and we will be suffer a little slow done because we are not an island”. Unfortunately it occurs not to be true.Based on discourse analysis of two major Polish daily and two weekly we would like to show the evolution of narrative describing crises in global terms and particularly at the domestic market. What was the picture of global crises at the beginning of this discussion, how it supposed to affect Poland, who serve as experts and opinion givers and finally how through the language we can observe the change from ‘slow down’ to ‘crises’? This are basic questions we would like to answer in our text.

  6. The effects of local street network characteristics on the positional accuracy of automated geocoding for geographic health studies

    Directory of Open Access Journals (Sweden)

    Zimmerman Dale L

    2010-02-01

    Full Text Available Abstract Background Automated geocoding of patient addresses for the purpose of conducting spatial epidemiologic studies results in positional errors. It is well documented that errors tend to be larger in rural areas than in cities, but possible effects of local characteristics of the street network, such as street intersection density and street length, on errors have not yet been documented. Our study quantifies effects of these local street network characteristics on the means and the entire probability distributions of positional errors, using regression methods and tolerance intervals/regions, for more than 6000 geocoded patient addresses from an Iowa county. Results Positional errors were determined for 6376 addresses in Carroll County, Iowa, as the vector difference between each 100%-matched automated geocode and its ground-truthed location. Mean positional error magnitude was inversely related to proximate street intersection density. This effect was statistically significant for both rural and municipal addresses, but more so for the former. Also, the effect of street segment length on geocoding accuracy was statistically significant for municipal, but not rural, addresses; for municipal addresses mean error magnitude increased with length. Conclusion Local street network characteristics may have statistically significant effects on geocoding accuracy in some places, but not others. Even in those locales where their effects are statistically significant, street network characteristics may explain a relatively small portion of the variability among geocoding errors. It appears that additional factors besides rurality and local street network characteristics affect accuracy in general.

    The aim of this study was firstly to describe the physiological responses observed in 19 subjects during immersion of the arm up to the elbow in water at 5 degrees C (5 min) followed by a 10-min recovery and secondly, to correlate the observed physiological responses with biometrical characteristics of the subjects (maximal oxygen uptake, VO2max, percentage fat content of whole body, BF, and arm, forearm and hand skinfold thickness). The results showed that the time courses of changes in forearm and hand skin temperature were different compared to those of finger skin temperatures both during local cooling and during rewarming (P immersion, decreased hand skin temperature was correlated to VO2max (r = 0.45, P < or = 0.05) whereas decreased forearm skin temperature was correlated both to VO2max (r = 0.44, P < or = 0.05) and to skinfold thickness (r = -0.44, P < or = 0.05) but not to BF. During the beginning of the recovery period only, outside, inside forearm and hand skin temperatures were related to VO2max (r = 0.54, P < or = 0.05; r = 0.66, P < or = 0.01 and r = 0.45, P < or = 0.05, respectively) and all the skinfold thicknesses (r = -0.47 to -0.71, P < or = 0.05). It was concluded that the local skin temperature profiles differed according to the upper limb segment both during cooling and during early rewarming. Moreover, VO2max and upper limb skinfold thickness but not BF did influence the forearm and hand skin temperature changes during cooling and early rewarming but not the finger skin temperature changes and cardiovascular responses.

    Innovative market mechanisms are being increasingly recognized as effective decision-making institutions to incorporate the value of ecosystem services into the economy. We present a field experiment that integrates an economic auction and a biophysical water flux model to develop a local market process consisting of both the supply and demand sides. On the supply side, we operate an auction with small-scale livestock owners who bid for contracts to implement site-specific manure management practices that reduce phosphorus loadings to a major reservoir. On the demand side, we implement a real money, multi-unit public good auction for these contracts with residents who potentially benefit from reduced water quality risks. The experiments allow us to construct supply and demand curves to find an equilibrium price for water quality improvement. The field experiments provide a proof-of-concept for practical implementation of a local market for environmental improvements, even for the challenging context of nonpoint pollution.

  15. Seasonal and Local Characteristics of Lightning Outages of Power Distribution Lines in Hokuriku Area

    Science.gov (United States)

    Sugimoto, Hitoshi; Shimasaki, Katsuhiko

    The proportion of the lightning outages in all outages on Japanese 6.6kV distribution lines is high with approximately 20 percent, and then lightning protections are very important for supply reliability of 6.6kV lines. It is effective for the lightning performance to apply countermeasures in order of the area where a large number of the lightning outages occur. Winter lightning occurs in Hokuriku area, therefore it is also important to understand the seasonal characteristics of the lightning outages. In summer 70 percent of the lightning outages on distribution lines in Hokuriku area were due to sparkover, such as power wire breakings and failures of pole-mounted transformers. However, in winter almost half of lightning-damaged equipments were surge arrester failures. The number of the lightning outages per lightning strokes detected by the lightning location system (LLS) in winter was 4.4 times larger than that in summer. The authors have presumed the occurrence of lightning outages from lightning stroke density, 50% value of lightning current and installation rate of lightning protection equipments and overhead ground wire by multiple regression analysis. The presumed results suggest the local difference in the lightning outages.

    The results of the seismic observations made with two different experimental setups are presented. In the first case, the signals produced by underground nuclear explosions at the Semipalatinsk Test Site were measured on a linear profile, which allowed one to definitely outline the areas where the mechanical properties of rocks experienced considerable time variations. In the second case, the waves excited by the open-pit mine blasts recorded at a small-aperture seismic array at the Mikhnevo Geophysical Station (Institute of Geosphere Dynamics, Russian Academy of Sciences) on the East European Platform favored the estimation of variations in the integral characteristics of the seismic path. Measurements in aseismic regions characterized by diverse geological structure and different tectonic conditions revealed similar effects of the strong dependency of seismic parameters on the time of explosions. Here, the variations experienced by the maximum amplitudes of oscillations and irrelevant to seasonal changes or local conditions reached a factor of two. The generic periods of these variations including the distinct annual rhythm are probably the fragments of a lower-frequency process. The obtained results suggest that these variations are due to changes in the stressstrain state of active fault zones, which, in turn, can be associated with the macroscale motion of large blocks triggered by tidal strains, tectonic forces and, possibly, variations in the rate of the Earth's rotation.

    1989-03-01

    Characteristics of edge localized mode (ELM/ERP) during H-mode plasma of JFT-2M were investigated. It was found that ELM/ERP is mainly a density fluctuation phenomena in the edge, and electron temperature in the edge except just near the separatrix is not very much perturbed. Several experimental conditions to controll ELM/ERP are, plasma density, plasma ion species, heating power, and plasma current ramping. ELM/ERPs found in low density deuterium discharge are suppressed by raising the density. ELM/ERPs are pronounced in hydrogen plasma compared with deuterium plasma. ELM/ERPs seen in hydrogen plasma or in near marginal H-mode conditions are suppressed by increasing the heating power. ELM/ERPs are found to be suppressed by plasma current ramp down, whereas they are enhanced by current ramp up. MHD aspect of ELM/ERP was investigated. No clear MHD features of ELM/ERP were found. However, reversal of mode rotation seen imediately after ELM/ERP suggests the temporal return to L-mode during the ELM/ERP event. (author)

    Intrapulmonary receptors identified in the Tegu lizard by single-unit vagal recording (Fedde et al., 1977) were subjected to a number of stimuli and localized within the lung. Some carbon dioxide receptors could follow periodic changes in intrapulmonary CO2 concentrations as rapidly as 1.3 Hz; No oxygen sensitivity was observed with this receptor type, and halothane markedly depressed the discharge frequency. In response to intravenously injected acetazolamide they increased their discharge frequency and became almost totally insensitive to CO2, suggesting molecular per se is not the direct controller of receptor discharge; These receptors show many of the functional characteristics described for those in the avian lung. Afferent activity from both CO2 and mechanoreceptors could be elicited by electrically stimulating the lung surface. The CO2 receptors appeared to be organized in a receptive field covering more than 1 cm2 of lung surface, multiple receptors being innervated by a single afferent fiber. Activity in afferent fibers from mechanoreceptors could be evoked from only one distinct spot on the lung surface. Conduction velocities of afferent fibers from CO2 receptors ranged from 1 to 3 m-sec-1; from mechanoreceptors, from 1.9 to 5.2 m-sec-1.

    Maria Irina DROMERESCHI

    2013-06-01

    Full Text Available Whatever his/her professional development would be, a young person needs a natural transition from being qualified to being competent. Here we find the dimensions of a multi-faceted investment in three areas: knowledge, „savoir-faire” or skill, and „savoir-etre” or compliance with one’s own position. All current economic issues are debated in terms of : value, integrity, character, knowledge, vision, responsibility, self-control, social integration, team work, community, competence, social responsibility, quality of life, fulfilment, leadership, duty, purpose, dignity, meaning. Scale technology needs people who have the future in their blood. That is why the basic aim of education should be to enhance the ability to adapt. When applied, the principle of diversity would result in a single system of techniques which work in three crucial areas : study, human relatioships and option. The ability to live involves different ways of sending information and behaviour simultanously and it will be the modern educator’s tool in making judgements. This paper assumes that economic education in general and entrepreneurship in paricular, help young people to perceive, to identify and to understand the factors that, influence their life quality directly or indirectly, to contribute to the development of the economy, and to a better management of society. Moreover, entrepreneurship education instils respect for value, work and innovation. One way of putting this kind of education into practice is by school partnerships.

    Full Text Available Immunization is a key element of public health, a pre-requisite to social and economic development, and a crucial element that enables every child to reach his or her full physical and intellectual potential. It is a prevention against various child killer diseases such as tuberculosis (Bacillus Calmette Gurine [BCG], tetanus, whooping cough, diphtheria, poliomyelitis, hepatitis B, yellow fever, and measles. The main objective of this study is to examine the relationships between household characteristics, social mobilization, and immunization status of under-5 children in Lagos metropolis, Nigeria. To achieve this objective, a non-experimental research design was adopted. The research method utilized in the design is cross-sectional survey. The sampled study location is Ojo local government area of Lagos State. A total of 265 respondents were randomly sampled for the survey using multistage random sampling technique. Generated data were analyzed using univariate, bivariate, and multivariate statistical techniques. The findings of the study reveal significant relationship between women’s level of education and full immunization of their children. Specifically, 38.9% of women without any formal education had fully immunized their children compared with 86.9% of women with secondary education. In addition, 90.9% of women who assessed themselves to be average on wealth assessment compared with 45.3% of the poor had fully immunized their children. On the basis of the study’s findings, there is a need for a holistic approach that will involve all social classes and communities on child immunization to have 100% immunization coverage and minimal child morbidity and mortality in all areas of the city.

    2014-01-01

    The theory of compensating differentials asserts that night shift workers should receive compensating wage differentials due to undesirable work conditions. In weak local economies, workers may have difficulty finding jobs; thus, these workers might be more likely to accept night shift work and be less concerned with the size of the compensating differential for night shifts. Using CPS data from 2001, this paper employs maximum likelihood estimation of an endogenous switching regression model...

  2. Local Economic Development and Hydropower Along the Brahmaputra River Basin in Northeast India

    Mock, A.

    2014-12-01

    Large dams have long been controversial. They offer benefits, such as reduced greenhouse gas emissions, energy security, and local development, yet produce negative social and ecological impact, such as wildlife habitat destruction, human displacement, and the disruption of downstream fishing or agricultural industries. In the past decade, the Indian government has signed Memoranda of Understanding with hydroelectric power companies for the building of over 130 large dams on the Brahmaputra River in the state of Arunachal Pradesh in Northeast India. These dams can generate 43% of India's assessed hydropower potential to sustain India's growing economy. In addition, the Indian government claims that these dams will bring local development with needed jobs. However, local Arunachali people have protested and temporarily halted hydropower projects because of the impact of dams on their existing livelihoods. Using the North Eastern Electric Power Corporation's (NEEPCO) Ranganadi Hydroelectric Project as a case study, our project examined whether dams in Northeast India provide jobs for local people, and whether distance from the dam or work colony to a worker's hometown affects the type of job the worker received. Survey data from residents at NEEPCO's work colony in Doimukh, Arunachal Pradesh, was analyzed using SPSS (n = 18). Our research found that 100% of workers at the dam originally resided in Northeast India, with 33% from Arunachal Pradesh, and 67% from the nearby states of Assam, and Tripura. Further, our analysis revealed no statistically significant relationship between the distance to a worker's hometown and job type (p = .609). Where workers come from did not affect the type of job they received. More research using a larger sample size and additional hydroelectric project case studies is needed to further explore the relationship between worker home location and their job types.

    Full Text Available This paper presents the effects of Indonesian government’s developmental efforts of assistance and training performed  on the growth of LED-SME business units and business performance. Both parameters of the government’s assistance and training were used to analyze the impact to the  growth and performance of business unit. To achieve a comprehensive result, samples acquired in this research were about 190 entrepreneurs and managers of LED-SME from East Java. Based on the parameters above, there are five hypotheses made to prove the relationship of the assistance and training to the growth and performance of business units. The structural equation modeling (SEM was carried out to test the hypotheses. The results have shown that the government’s developmental efforts through both assistance and training for the LED-SME were capable on increasing growth and performance of business units. On the other hand, government’s developmental efforts through only trainings were incapable of directly affecting growth of LED-SME business units and performance. To improve the business unit and performance, the government needs to implement developmental principles of LED-SME with the basis of utilizing local natural resources and also the communities of LED-SME as main suppliers for their local markets. In addition, preservation and development of local cultural and traditional arts also need to be the government’s main concern.

    Although many antibodies are being used for imaging studies, it is not clear which in vitro properties of antibodies will best reflect their in vivo characteristics. The ability to correlate in vitro binding characteristics of monoclonal antibodies to tumor antigens with their in vivo localization characteristics, particularly with respect to tumor localization properties, is desirable for rapid selection of monoclonal antibodies with potential for clinical use. The in vitro binding characteristics of three monoclonal antibodies to the murine Ly-2.1 antigen and one to the Ly-3.1 antigen have been studied on cultured tumor cells bearing these antigens. The association and dissociation rate constants, apparent affinity, and immunoreactivity of each antibody in vitro were compared with their ability to localize the s.c. tumors from the same cell line growing in Ly-2.1-/Ly-3.1-mice. The antibody with the highest affinity and fastest association rate localized to tumor at the earliest time (16-20 h after injection) and had the highest percentage of the injected dose/g in the tumor (greater than 25%). The antibody with the lowest affinity showed significantly less localization to tumor cells, compared with the other three antibodies. The ranking of the antibodies by affinity agreed with the ranking in terms of their ability to localize to tumors, but the in vitro immunoreactivity of the antibodies, as measured by a cell binding assay, did not correlate with their tumor localization properties. Immunoscintigraphic studies did not precisely correlate with biodistribution data or in vitro binding characteristics, because tumors could be satisfactorily imaged with each antibody, although it was noted that the antibody with the highest affinity gave the best image

    Full Text Available The democratic dispensation of the post-1994 government in South Africa promised a better life for all. However, shortly after the establishment of new polices by government and governance institutions, the promise faced conflicting socio/politico/economic challenges. One of the key issues to be considered when deciding on the implementation of overdue promises is the question of equitable distribution of resources and how to manage this process. Despite the above explanations few benefits arose from the application of these arguments. It appears that because of challenges at the highest levels of the tourism industry, real benefits have not yet reached people who are in need. This state of affairs provided an opportunity to propose workable recommendations to improve the situation, with the intention of positively influencing the various impacts that such development would have on the relevant communities.

    Raw milk, raw fruit juice and raw fish are enriched with essential nutrients for human diet but are prone to microbial contamination along the value chain. This cross sectional study was conducted to assess physicochemical characteristics and microbial quality of raw milk, fruit juice and fish from food vendors in Morogoro Municipality, Tanzania. The physicochemical assessment of food samples was done by smell, colour, presence of debris, turbidity, consistence, pH and clot on alcohol test. Hygiene of food containers, personnel and the vending environment was also assessed. Qualitative and quantitative microbial assessment of food was done using standard laboratory protocols as described by Tanzania Bureau of Standards and International Systems of Standards. Raw milk sold in Morogoro was of poor quality since was adulterated with water, contained sediments and clotted on alcohol test. Up to 63 % of the milk samples were contaminated with Escherichia coli and 60 % had higher total viable count (TVC) than the recommended values. Raw fruit juice was stored in dirty containers and sold under unhygienic environment. Seventy-three percent of juice samples had TVC beyond the recommendations while E. coli contamination rate was 63.3 %. The raw fish samples had started spoiling as depicted through sensory evaluation. E. coli contamination rate was 55 % and that of Campylobacter jejuni was 0.5 %. The mean TVC of raw fish was 8.1 (Log cfu/g) and 96.2 % of the fish samples had TVC beyond the recommended limits of 5.0 Log cfu/g. The physicochemical characteristics of food vended in Morogoro Municipality were of poor quality. The food had high bacterial contaminations. This situation poses health risks to the public and losses to food vendors due to spoilage. Stakeholders in food value chain should be educated on safe production and good hygienic practices.

    2010-12-01

    Full Text Available Tourism has represented one of the major sources of balance of trade earnings for many years in the most developed countries. According to estimates by the World Tourism Organization (WTO, world tourism flows will grow by 4-5% annually over the coming years, reaching in 2020 an estimated number of 1.6 billion international arrivals, of which 378 million will be short haul international travellers. With the passage of time demand will become more diversified and this will lead to the spread of “new tourism”, the search for new products and increasingly diverse offers, characterized by organized local tourist systems.This paper underlines the importance of the tourist district model as a strategic tool for creating innovative processes of endogenous development in a highly globalized framework, moreover it tries to highlight the peculiarities of tourist districts and their importance in overcoming the major limitations of the distribution chain. Therefore, the birth of the tourism district represents an important opportunity for the promotion of tourism development of different local realities.

    Full Text Available Authors analyze the problem to find the optimal policy options to stimulate economic growth in modern conditions. They point out three possible options for such policy according to the different structural priorities. This point causes the question of the extent to which the proposed policy approaches to stimulate economic growth correspond to real economic trends. The solution of this problem is possible only on the basis of the empirical study analysis results. Also it is necessary to take into account the regional dimension related to the fact that the various sectors of the economy linked to the various regions. According to this fact one may point out Russian regions with the predominance of the mining industry, manufacturing industry and services. Authors exploit panel dataset on 80 Russian regions for the period 2005-2014 to analyze the relationship between annual shares of sectors in output and employment and per capita gross regional growth. Results indicate that regions with a higher share of manufacturing and mining both in terms of output and employment grow slower during the reporting period. The impact of services on growth is somewhat paradoxical: regions with bigger shares of healthcare and education in output growth faster, but a bigger share of this sector in employment, as much as expanding of the labor share of these sectors impede growth. Possible reason for this paradox is that the high proportion of services in the regions-leaders (especially the share of total employment reflects not the degree of their development, but the development of the public sector in relatively poor regions. The results show that neither manufacturing nor mining and services are not the engines of economic growth that can ensure sustainable development of the whole economy. Authors point out that it is necessary to conduct multivariate policies to stimulate economic growth, which is based on the various configurations of developmental actors

  15. The role of place branding in local and regional economic development: bridging the gap between policy and practicality

    Full Text Available Place branding has become an increasingly integral part of local and regional economic development strategies in the global competition for business investment. Professional and academic understanding remains limited, however, regarding whether place branding can be classified as a ‘high-road’ policy with substantive and effective merits or a ‘low-road’ policy that is generally inefficient and ineffective at fostering sustainable economic growth. Through the context of business attraction, this study examines whether place branding represents ‘high-road’ policy by comparing what economic development practitioners are doing to create and support their brands against the needs and desires of businesses considering relocation. The research goal is achieved through a series of in-depth interviews with economic development practitioners (n = 25 and private-sector site selectors (n = 10 in the province of Ontario, Canada. Gaps between policy and practicality are identified by comparing the responses of the two groups. Results demonstrate that place branding has the potential to be ‘high-road’ policy given its utility in business attraction. In its current implementation, however, place branding remains better described as a ‘low-road’ policy, as it is not being used efficiently. Several gaps in place-branding policy are identified, including an overreliance on visual identities and narratives, poor communication of the brand information, and overemphasis on presenting quality of life and affordability. These gaps present possible areas of ineffectiveness that can limit the ability of a place brand to attract investment, but provide areas of future policy improvements, thus enabling place branding to shift from ‘low road’ to ‘high road’.

    Full Text Available Indonesia regional feeder ports’ main function is to serve marine transport activities between regency/city in a province in limited quantities. The intention of the government to make marine transportation as the backbone of national logistic transportation system puts these ports to an important position, as suppliers for the main and/or collector ports and as goods distribution centers for the region from the bigger ports. Not only as a provider of accessibility between regions, regional feeder ports should be seen as an investation to boost regional economy. This study aims to explain the influences of regional feeder ports on regency/city economy, based on the port types: (1 cargo ports, and (2 cargo & passengers ports. Results showed that both types of ports have positive influences on the regency/city economy, although it is not related to region’s economic base sector. Cargo ports which are mainly located on west area of Indonesia, supports the region’s economy more than cargo & passenger ports which are mainly located on the east.

The theme corresponds to a challenge to address it having as main axis of discussion either the problem of social exclusion or that of local development. The reasons to locate the discussion in this last field of analysis are discussed in the first part of the text. Theoretical and political reasons are there articulated because the question is about projects whose intentions and practices call for the political both in the theoretical debate and in the choices that anticipate intervention. From research conducted for several years, I use contributions that aim at discuss and enlighten how school can be a potential locus of local development. Its identification and recognition as local institution (either because of those that work and live in it or because of those that act in the surrounding context are crucial steps to progressively constitute school as a partner for development. The promotion of the local values and roots, the reconstruction of socio-personal and local identities, the production of sociabilities and the equation and solution of shared problems were the dimensions of a socio-educative intervention, markedly globalising. This scenario, as it is argued, was also, intentionally, one of transformation and of deliberate change of school and of the administration of the educative territoires.

The one-year prevention program was administered to children in 28 of 56 Swiss elementary schools (N = 1,675. Outcomes were assessed at pretest and posttest with a follow-up 2 years later. Moderator interactions involving baseline child characteristics and economic factors were tested. There were significant treatment effects for ADHD/impulsivity and aggression at the follow-up. Baseline development variables predicted higher prosocial behavior as well as lower aggressive behavior and ADHD at the follow-up. Economic risk factors predicted poor behavior outcomes at the follow-up. Development variables moderated the impact of PATHS on ADHD and aggression at the follow-up. However, for most outcomes, no main effects or moderation of treatment effects were found.

    Renewable sources represent an effective alternative to fossil fuels for preventing resources depletion and for reducing air pollution. However, their diffusion requires huge capital investment and major infrastructure changes, which have to be assessed to verify their effectiveness. The article present an application of the R-MARKAL model to investigate the feasibility of renewable use on a local case study for electricity and thermal energy production. A comprehensive modelling approach is used to emphasise the relationships and feedback between conversion and demand sectors (residential, services and commercial), taking into account contemporaneously legal issues and physical limits of the system. The model's solutions represent the minimum cost choice and the results show that even in absence of erogenous environmental constraints, many renewable technologies are profitable demand device and their investment costs are paid off in a medium term by lower operating and maintenance expenditures. In this context the use of thermal energy from incinerator allows one to achieve a consistent reduction of atmospheric pollutant emissions and, particularly, of greenhouse gases emissions due to waste degradation.

    In the context of the nutrition transition and associated changes in the food retail sector, to examine the socio-economic characteristics and motivations of shoppers using different retail formats (large supermarkets (LSM), medium-sized supermarkets (MSM) or traditional outlets) in Tunisia. Cross-sectional survey (2006). Socio-economic status, type of food retailer and motivations data were collected during house visits. Associations between socio-economic factors and type of retailer were assessed by multinomial regression; correspondence analysis was used to analyse declared motivations. Peri-urban area around Tunis, Tunisia, North Africa. Clustered random sample of 724 households. One-third of the households used LSM, two-thirds used either type of supermarket, but less than 5 % used supermarkets only. Those who shopped for food at supermarkets were of higher socio-economic status; those who used LSM were much wealthier, more often had a steady income or owned a credit card, while MSM users were more urban and had a higher level of education. Most households still frequently used traditional outlets, mostly their neighbourhood grocer. Reasons given for shopping at the different retailers were most markedly leisure for LSM, while for the neighbourhood grocer the reasons were fidelity, proximity and availability of credit (the latter even more for lower-income customers). The results pertain to the transition in food shopping practices in a south Mediterranean country; they should be considered in the context of growing inequalities in health linked to the nutritional transition, as they differentiate use and motivations for the choice of supermarkets v. traditional food retailers according to socio-economic status.

  6. A novel chaotic particle swarm optimization approach using Henon map and implicit filtering local search for economic load dispatch

    Coelho, Leandro dos Santos; Mariani, Viviana Cocco

    2009-01-01

    Particle swarm optimization (PSO) is a population-based swarm intelligence algorithm driven by the simulation of a social psychological metaphor instead of the survival of the fittest individual. Based on the chaotic systems theory, this paper proposed a novel chaotic PSO combined with an implicit filtering (IF) local search method to solve economic dispatch problems. Since chaotic mapping enjoys certainty, ergodicity and the stochastic property, the proposed PSO introduces chaos mapping using Henon map sequences which increases its convergence rate and resulting precision. The chaotic PSO approach is used to produce good potential solutions, and the IF is used to fine-tune of final solution of PSO. The hybrid methodology is validated for a test system consisting of 13 thermal units whose incremental fuel cost function takes into account the valve-point loading effects. Simulation results are promising and show the effectiveness of the proposed approach.

    2015-12-01

    Full Text Available The object of this article is to analyze and asses the legal and economic consequences arising from the adoption (or change of a local spatial development plan. The paper also presents, based on the example of the rural commune of Tomice in the Malopolska Province of Poland, how to estimate income to the commune budget from the collected planning fees. The analyses are based on planning studies, including the local spatial development plan from 2004, and the study of conditions and directions of spatial development from 2012. The council of Tomice Commune adopted the local spatial plan due to the increasing demand for residential areas. According to the plan, over 930 acres of land have been allocated for investment purposes, which is approx. 22.4% of the total area of 4,155 ha. The local plan was developed for all the six cadastral units of the commune, with one hundred percent surface coverage. The physiographic conditions and the location of Tomice Commune encourage the settlement of the urban population (from Wadowice or Krakow, which entails the need for housing investment areas. In 2012, the Tomice Commune adopted a change in the study of conditions and directions of spatial development. The proposed re-zoning of the area is in line with the policy of transitioning from an agricultural character towards the sustainable and multifunctional development of the commune. It is worth noting that the provisions of the plan of 2004 take into account the collection of a one-time fee for the sale of real estate whose value has increased as a result of the adoption of the plan. The amount of this fee for investment areas was set at the level of 30% of the increase in value, in accordance with the provisions of the Polish Act on Spatial Planning and Management. Due to the fact that the currently valid local plan has been in effect for 10 years, it can be assumed that the commune will proceed to make some changes to it. The article estimates the

    There is a need to explore more sustainable approaches to water management on the Canadian Prairies. Retention pond installation schemes designed to capture surface water may be a viable option that would reduce water stress during drought periods by providing water for irrigation. The retention systems would serve to capture excess spring runoff and extreme rainfall events, reducing flood potential downstream. Additionally, retention ponds may be used for biomass production and nutrient retention. The purpose of this research was to investigate the economic viability of adopting local farm surface water retention systems as a strategic water management strategy. A retention pond was analyzed using a dynamic simulation model to predict its storage capacity, installation and upkeep cost, and economic advantage to farmers when used for irrigation. While irrigation application increased crop revenue, the cost of irrigation and reservoir infrastructure and installation costs were too high for the farmer to experience a positive net revenue. Farmers who harvest cattails from retention systems for biomass and available carbon offset credits can gain 642.70/hectare of harvestable cattail/year. Cattail harvest also removes phosphorus and nitrogen, providing a monetized impact of 7014/hectare of harvestable cattail/year. The removal of phosphorus, nitrogen, carbon, and avoided flooding damages of the retention basin itself provide an additional 17,730-18,470/hectare of retention system/year. The recommended use of retention systems is for avoided flood damages, nutrient retention, and biomass production. The revenue gained from these functions can support farmers wanting to invest in irrigation while providing economic and environmental benefits to the region.

    A pervasive cultural practice called 'jaboya' or women trading sex for fish exists at Nyamware Beach, on Lake Victoria in Kenya, where the fishing industry is the primary source of income. This case study describes how an innovative market-based solution succeeded in changing the gender dynamics on Nyamware beach and empowering women with the means of production in the industry. Over the course of 6 months, three boats were built for women to own and manage, and 29 women and 20 men received business skills training while establishing local community savings and loans associations. This project succeeded in quickly adjusting the economic imbalance that previously left women few options but to exchange sex to purchase the best fish for food and for distribution. Participating women applied resulting increased income to school fees for children and toward their households and businesses. Women owning businesses, earning income and gaining a voice in the community has changed the gender dynamics of men working on the boats for women and has positively altered the perception of women in the community. Additionally, this project offers potential health benefits such as a reduction in the transmission of HIV/AIDS and other sexually transmitted infections due to reduced rates of transactional sex, and reduced rates of depression, alcohol abuse and post-traumatic stress disorder from transactional sex, which can be traumatic. The success of this project demonstrates that small and innovative approaches addressing root causes of economic and social inequality can improve health and promote sustainable economic development. © The Author 2016.

    Full Text Available Abstract Smallholder livestock farmers in Nigeria utilize traditional medicines derived from medicinal plants (PMs for the maintenance of their animals' health. This study was designed to determine the PMs used in the study area and their level of utilization by livestock farmers, compare the level of utilization of PMs across the three states surveyed and identify the socio-economic factors influencing farmer's utilization of PMs. Thirty-five PMs were identified. Farmers had considerable knowledge about the identified PMs but about 80.0% of them used the PMs to poor/moderate extent. There were statistical differences in the utilization level of PMs among the three states. Six socio-economic variables were found to be statistically significant in influencing PMs' utilization. Farmer's age, household size, distance to the nearest veterinary hospital/clinic and extent of travels, had positive effects while negative effects were exhibited by farm income and number of heads of livestock. It was concluded that there was considerable knowledge about PMs and that utilization of PMs varied between the three states. It was recommended that local knowledge of PMs be preserved in the study area through screening and documentation.

    Full Text Available Application of fly ash in the construction industry is particularly significant in the terms of environmental protection and in the terms of improvement opportunities of certain properties of cement mortar and concrete. In addition to this, it is possible to perform the recultivation of significant area of agricultural land. Concrete production precedes the production of lightweight aggregate which is then used as an aggregate. Calculated costs of concrete production using lightweight aggregate were 70.52 €/m3. Most of these costs are energy costs in the sum of 85% of total costs. In the situation when the costs of concrete production using lightweight aggregate are compared to the concrete price at the market, or produced with the use of construction gravel, estimation of the economic viability gives a negative result. This result is caused by the high cost of the aggregate. The observed calculation did not include an improved thermal-insulating property of concrete and reduce pollution through binding of waste ash. According to this, final assessment can only be made after extensive technological, macroeconomic and environmental analysis. Economic analysis should be primarily based on the value of land that can be recultivation in this way.

    Full Text Available Following the crisis generated by the financialization of private real-estate, construction prices have gradually decreased depriving the housing market of the necessary growth stimuli. Many countries have set up measures to revive this highly strategic area for the national economy. With reference to the Campania Region Law n. 19 dated 28 December 2009, known Housing Plan, this work has two objectives: to recognize the fundamental estimation problems that need to be solved in the implementation of the Campania Housing Plan; in addition, predict the effects of the regulations on the regional economy, both in overall terms as well as for each production sector, with particular attention being given to the construction industry. Regarding the first objective, the contents of the law are analysed on the basis of the principles that govern the appraisal. The consequences of the Campania Housing Plan on the economic system are then evaluated using input-output matrices, which are able to capture the structural relationships that exist among the various productive sectors. The numerical calculations require a preliminary investigation aimed at collecting a list of interventions approved by local governments in accordance to the Housing Plan. The cost of the works, as proposed in the applications submitted to the local administrations, is the input data for the implementation of the Social Accounting Matrix 2010 of the Campania Region.

    Full Text Available BACKGROUND: The aim of this study is to give a description of the road traffic injuries (RTIs characteristics of floating migrant population by comparing with those of local residents in a harbor city of China. METHODS: A population-based descriptive study was carried out between 2007 and 2010 with RTI patient records from the Fifth Center Hospital of Tianjin. Inpatient diagnoses of RTI patients were defined using the International Classification of Diseases, Tenth Revision (ICD-10 codes. We analyzed the demographics and general characteristics of RTI patients that were in the hospital during the four years. In order to compare the group differences between local resident patients and floating migrant patients, the distribution of their ages, diagnoses, severity of injuries, duration of inpatient stays, hospitalization cost were analyzed. RESULTS: People between the ages of 16 and 55 were the most likely to suffer RTIs. The floating migrant patients between the ages of 16 and 45 had a higher incidence of accidents, while local resident patients between 46 and 55 had a higher incidence of accidents. Compared to local resident patients, floating migrant patients were more vulnerable to open injuries and severe traffic injuries. With the severity of injuries ranked from mild to severe, floating migrant patients had lower duration of inpatient stay, but higher hospitalization costs compared to local resident patients. CONCLUSIONS: Floating migrant patients had a different age distribution, severity of injuries, diseases, inpatient duration and hospitalization cost compared with local resident patients. Compared to local resident patients, floating migrants had a higher risk to RTIs and were more vulnerable to severer traffic accidents at lower ages.

    A 4-yr study was conducted using 736 steers of known Angus, Simmental, or Simmental × Angus genetics to determine performance, carcass, and feed efficiency factors that explained variation in economic performance. Steers were pen fed and individual DMI was recorded using a GrowSafe automated feeding system (GrowSafe Systems Ltd., Airdrie, Alberta, Canada). Steers consumed a similar diet and received similar management each year. The objectives of this study were to: 1) determine current economic value of feed efficiency and 2) identify performance, carcass, and feed efficiency characteristics that predict: carcass value, profit, cost of gain, and feed costs. Economic data used were from 2011 values. Feed efficiency values investigated were: feed conversion ratio (FCR; feed to gain), residual feed intake (RFI), residual BW gain (RG), and residual intake and BW gain (RIG). Dependent variables were carcass value ($/steer), profit ($/steer), feed costs ($/steer • d(-1)), and cost of gain ($/kg). Independent variables were year, DMI, ADG, HCW, LM area, marbling, yield grade, dam breed, and sire breed. A 10% improvement in RG (P Profit increased with a 10% improvement in feed efficiency (P profit. Eighty-five percent of the variation in cost of gain was explained by ADG, DMI, HCW, and year. Prediction equations were developed that excluded ADG and DMI, and included feed efficiency values. Using these equations, cost of gain was explained primarily by FCR (R(2) = 0.71). Seventy-three percent of profitability was explained, with 55% being accounted for by RG and marbling. These prediction equations represent the relative importance of factors contributing to economic success in feedlot cattle based on current prices.

    In recent years, modern economies have shifted away from being based on physical capital and towards being based on new knowledge (e.g., new ideas and inventions). Consequently, contemporary economic theorizing and key public policies have been based on the assumption that resources for generating knowledge (e.g., education, diversity of industries) are essential for regional economic vitality. However, policy makers and scholars have discovered that, contrary to expectations, the mere presence of, and investments in, new knowledge does not guarantee a high level of regional economic performance (e.g., high entrepreneurship rates). To date, this “knowledge paradox” has resisted resolution. We take an interdisciplinary perspective to offer a new explanation, hypothesizing that “hidden” regional culture differences serve as a crucial factor that is missing from conventional economic analyses and public policy strategies. Focusing on entrepreneurial activity, we hypothesize that the statistical relation between knowledge resources and entrepreneurial vitality (i.e., high entrepreneurship rates) in a region will depend on “hidden” regional differences in entrepreneurial culture. To capture such “hidden” regional differences, we derive measures of entrepreneurship-prone culture from two large personality datasets from the United States (N = 935,858) and Great Britain (N = 417,217). In both countries, the findings were consistent with the knowledge-culture-interaction hypothesis. A series of nine additional robustness checks underscored the robustness of these results. Naturally, these purely correlational findings cannot provide direct evidence for causal processes, but the results nonetheless yield a remarkably consistent and robust picture in the two countries. In doing so, the findings raise the idea of regional culture serving as a new causal candidate, potentially driving the knowledge paradox; such an explanation would be consistent with research

  20. Statistical characteristics of dynamics for population migration driven by the economic interests

    Population migration typically occurs under some constraints, which can deeply affect the structure of a society and some other related aspects. Therefore, it is critical to investigate the characteristics of population migration. Data from the China Statistical Yearbook indicate that the regional gross domestic product per capita relates to the population size via a linear or power-law relation. In addition, the distribution of population migration sizes or relative migration strength introduced here is dominated by a shifted power-law relation. To reveal the mechanism that creates the aforementioned distributions, a dynamic model is proposed based on the population migration rule that migration is facilitated by higher financial gains and abated by fewer employment opportunities at the destination, considering the migration cost as a function of the migration distance. The calculated results indicate that the distribution of the relative migration strength is governed by a shifted power-law relation, and that the distribution of migration distances is dominated by a truncated power-law relation. These results suggest the use of a power-law to fit a distribution may be not always suitable. Additionally, from the modeling framework, one can infer that it is the randomness and determinacy that jointly create the scaling characteristics of the distributions. The calculation also demonstrates that the network formed by active nodes, representing the immigration and emigration regions, usually evolves from an ordered state with a non-uniform structure to a disordered state with a uniform structure, which is evidenced by the increasing structural entropy.

  1. A review of some characteristics, socio-economic aspects and utilization of Zulu sheep: implications for conservation.

    Zulu sheep are Nguni sheep of Zululand and are adapted to the harsh conditions of KwaZulu-Natal. They are used by rural farmers for economic purposes. Their numbers are declining, indicating a potential extinction threat. Knowledge of their phenotypic and genotypic characteristics is essential for conservation planning. In this review, there is a focus on the utilization, socio-economic aspects, phenotypic and genotypic characteristics as well as a proposed breeding programme. A survey has shown that rural farmers in the areas of northern KwaZulu-Natal prefer to keep this breed for its adaptability, resistance to diseases and meat quality. Zulu sheep are small-framed multi-coloured animals. Mature males weigh up to 38 kg and females up to 32 kg. Based on four morphological traits and live weight, phenotypic diversity between three populations was estimated at 48%. A genetic diversity between these three populations was estimated at 22%. Live weight of Zulu sheep can be estimated using the heart girth and wither height measurements. Scrotum circumference of young rams (up to 22 months old) is reliable for estimating the live weight. Animals that were characterized in the studies were grazed extensively and no supplements were provided. There is therefore a potential of weight increase if these animals are reared in a semi-extensive environment. An open nucleus breeding scheme is thus recommended for a sustainable use and conservation of this breed. For more conclusive results, larger numbers of phenotypic and genetic characteristics, in larger numbers of Zulu sheep populations, should be investigated.

    Dry-gas deposits (methane ???95% of the hydrocarbon (HC) gases) are thought to originate from in-reservoir thermal cracking of oil and C2+ HC gases to methane. However, because methanes from Anadarko Basin dry-gas deposits do not carry the isotopic signature characteristics of C15+ HC destruction, an origin of these methanes from this process is considered improbable. Instead, the isotopic signature of these methanes suggests that they were cogenerated with C15+ HC's. Only a limited resource of deep-basin gas deposits may be expected by the accepted model for the origin of dry-gas deposits because of a limited number of deep-basin oil deposits originally available to be thermally converted to dry gas. However, by the models of this paper (inefficient source-rock oil and gas expulsion, closed fluid systems in petroleum-basin depocenters, and most dry-gas methane cogenerated with C15+ HC's), very large, previously unrecognized, unconventional, deep-basin gas resources are expected. -from Author

    Much of the research examining the patterns, timing, and socioeconomic characteristics of child overweight has been limited by the lack of longitudinal nationally representative data with sufficiently large or diverse samples. We used the Early Childhood Longitudinal Study- Kindergarten Cohort (ECLS-K), a nationally representative sample of US kindergartners, to identify three distinct patterns of weight gain from kindergarten through eighth grade. The largest group (boys: 59%, girls: 55%) was characterized as having consistently normal weight whereby BMI percentile remained below the 85th percentile. The remaining children (boys: 41%, girls: 45%) fell either into a class characterized as always overweight/at risk of overweight (boys: 27%, girls: 25%) or gradually becoming overweight/at risk for overweight (boys: 15%, girls 20%). We found some evidence that the relationship between socioeconomic status and children’s health may operate differently across gender. Among girls, low parental income and education were both significant risk factors for the gradual onset of overweight after beginning Kindergarten. Parental income or changes in parental income were not related to boys’ risk of developing overweight after entering Kindergarten; only parents’ education. We found that while children of immigrants display higher levels of overweight / at risk for overweight at each grade level, the children of immigrant parents who have had less exposure to the US were more likely to experience early and sustained overweight throughout elementary and middle school, particularly among boys. High rates of overweight as early as kindergarten, combined with race/ethnic differences suggest that interventions should focus on pre-school children’s environments. PMID:20535537

    To estimate the contribution of fast food to daily energy intake, and compare intake among Canadians with varied demographic, socioeconomic and lifestyle characteristics. Using the National Cancer Institute method, nationally representative estimates of mean usual daily caloric intake from fast food were derived from 24-hour dietary recall data from the Canadian Community Health Survey Cycle 2.2 (n = 17,509) among participants age ≥ 2 years. Mean daily intake and relative proportion of calories derived from fast food were compared among respondents with diverse demographic (age, sex, provincial and rural/urban residence), socio-economic (income, education, food security status) and health and lifestyle characteristics (physical activity, fruit/vegetable intake, vitamin/ mineral supplement use, smoking, binge drinking, body mass index (BMI), self-rated health and dietary quality). On average, Canadians reported consuming 146 kcal/day from fast food, contributing to 6.3% of usual energy intake. Intake was highest among male teenagers (248 kcal) and lowest among women ≥ 70 years of age (32 kcal). Fast food consumption was significantly higher among respondents who reported lower fruit and vegetable intake, poorer dietary quality, binge drinking, not taking vitamin/mineral supplements (adults only), and persons with higher BMI. Socio-economic status, physical activity, smoking and self-rated health were not significantly associated with fast food intake. While average Canadian fast food consumption is lower than national US estimates, intake was associated with lower dietary quality and higher BMI. Findings suggest that research and intervention strategies should focus on dietary practices of children and adolescents, whose fast food intakes are among the highest in Canada.

    Analysis of the results of long-term investigations of bones in cosmonauts flown on the orbital station MIR and International space station (n = 80) was performed. Theoretically predicted (evolutionary predefined) change in mass of different skeleton bones was found to correlate (r = 0.904) with position relatively the Earth's gravity vector. Vector dependence of bone loss ensues from local specificity of expression of bone metabolism genes which reflects mechanic prehistory of skeleton structures in the evolution of Homo erectus. Genetic polymorphism is accountable for high individual variability of bone loss attested by the dependence of bone loss rate on polymorphism of certain bone metabolism markers. Parameters of one and the other orbital vehicle did not modulate individual-specific stability of the bone loss ratio in different segments of the skeleton. This fact is considered as a phenotype fingerprint of local metabolism in the form of a locus-unique spatial structure of distribution of noncollagenous proteins responsible for position regulation of endosteal metabolism. Drug treatment of osteoporosis (n = 107) evidences that recovery rate depends on bone location; the most likely reason is different effectiveness of local osteotrophic intervention into areas of bustling resorption.

    To assess specific imaging characteristics after irreversible electroporation (IRE) for locally advanced pancreatic carcinoma (LAPC) with contrast-enhanced (ce)MRI and ceCT, and to explore the correlation of these characteristics with the development of recurrence. Qualitative and quantitative analyses of imaging data were performed on 25 patients treated with percutaneous IRE for LAPC. Imaging characteristics of the ablation zone on ceCT and ceMRI were assessed over a 6-month follow-up period. Contrast ratio scores between pre- and post-treatment were compared. To detect early imaging markers for treatment failure, attenuation characteristics at 6 weeks were linked to the area of recurrence within 6 months. Post-IRE, diffusion-weighted imaging (DWI)-b800 signal intensities decreased in all cases (p < 0.05). Both ceMRI and ceCT revealed absent or decreased contrast enhancement, with a hyperintense rim on ceMRI. Ablation zone volume increase was noted on both modalities in the first 6 weeks, followed by a decrease (p < 0.05). In the patients developing tumour recurrence (5/25), a focal DWI-b800 hyperintense spot at 6 weeks predated unequivocal recurrence on CT. The most remarkable signal alterations after pancreatic IRE were shown by DWI-b800 and ceMRI. These early imaging characteristics may be useful to establish technical success and predict treatment outcome. (orig.)

    Based on the results of exact analytic calculations, we show that topological edge states and impurities in quantum dimerized chains manifest themselves in various local static and dynamical characteristics, which can be measured in experiments. In particular, topological edge states can be observed in the magnetic field behavior of the local magnetization or magnetic susceptibility of dimerized spin chains as jumps (for the magnetization) and features (for the static susceptibility) at zero field. In contrast, impurities reveal themselves in similar jumps and features, however, at nonzero values of the critical field. We also show that dynamical characteristics of dimerized quantum chains also manifest the features, related to the topological edge states and impurities. Those features, as a rule, can be seen more sharply than the manifestation of bulk extended states in, e.g., the dynamical local susceptibility. Such peculiarities can be observed in one-dimensional dimerized spin chains, e.g., in NMR experiments, or in various realizations of quantum dimerized chains in optical experiments.

    Edge-localized modes (ELMs) are the focus of tokamak edge physics studies because the large heat loads associated with ELMs have great impact on the divertor design of future reactor-grade tokamaks such as ITER. In the experimental advanced superconducting tokamak (EAST), the first ELMy high...... confinement modes (H-modes) were obtained with 1 MW lower hybrid wave power in conjunction with wall conditioning by lithium (Li) evaporation and real-time Li powder injection. The ELMs in EAST at this heating power are mostly type-III ELMs. They were observed close to the H-mode threshold power and produced...

    Empirical research on the local economic effects associated with decentralized electricity generation from renewable sources has only just started. So far, most studies focus on quantifying economic effects and neglect the conditions and constellations which support and enable local economic development based on decentralized electricity generation. This, however, is the focus of this paper which looks at these issues, employing the value chain concept in combination with a governance perspective. Empirically, we take a qualitative approach and analyze two case studies of pioneer regions, in which decentralized electricity generation from renewable sources has developed very dynamically. The case study regions are Soltau, with a special focus on biogas production, and Emden, where wind energy plays a special role. Based on the early activities of some pioneers, these regions have developed specific actor constellations and organizational structures and have entered development paths in which renewable energies became an important economic factor. The analysis highlights the importance of institutional context and supportive governance structures for an early advancement of decentralized electricity generation from renewable sources, with a key role of local actors and governance constellations. It also points to the importance of cooperative relationships among local business actors for creating a competitive advantage for (some) regional firms. Our analysis shows that with the geographical proliferation of electricity generation from renewable sources, specialized firms tend to reach beyond their regions, thus offering first-mover advantages for firms in pioneer regions in comparison with latecomers.

  20. Research on the Band Gap Characteristics of Two-Dimensional Phononic Crystals Microcavity with Local Resonant Structure

    Full Text Available A new two-dimensional locally resonant phononic crystal with microcavity structure is proposed. The acoustic wave band gap characteristics of this new structure are studied using finite element method. At the same time, the corresponding displacement eigenmodes of the band edges of the lowest band gap and the transmission spectrum are calculated. The results proved that phononic crystals with microcavity structure exhibited complete band gaps in low-frequency range. The eigenfrequency of the lower edge of the first gap is lower than no microcavity structure. However, for no microcavity structure type of quadrilateral phononic crystal plate, the second band gap disappeared and the frequency range of the first band gap is relatively narrow. The main reason for appearing low-frequency band gaps is that the proposed phononic crystal introduced the local resonant microcavity structure. This study provides a good support for engineering application such as low-frequency vibration attenuation and noise control.

    This study evaluated the atmospheric dispersion of radioactive material according to local weather conditions and emission conditions. Local weather conditions were defined as 8 patterns that frequently occur around the Kori Nuclear Power Plant and emission conditions were defined as 6 patterns from a combination of emission rates and the total number of particles of the {sup 137}Cs, using the WRF/HYSPLIT modeling system. The highest mean concentration of {sup 137}Cs occurred at 0900 LST under the ME4{sub 1} (main wind direction: SSW, daily average wind speed: 2.8 ms{sup -1}), with a wide region of its high concentration due to the continuous wind changes between 0000 and 0900 LST; under the ME3 (NE, 4.1 ms{sup -1}), the highest mean concentration of {sup 137}Cs occurred at 1500 and 2100 LST with a narrow dispersion along a strong northeasterly wind. In the case of ME4{sub 4} (S, 2.7 ms{sup -1}), the highest mean concentration of {sup 137}Cs occurred at 0300 LST because {sup 137}Cs stayed around the KNPP under low wind speed and low boundary layer height. As for the emission conditions, EM1{sub 3} and EM2{sub 3} that had the maximum total number of particles showed the widest dispersion of {sup 137}Cs, while its highest mean concentration was estimated under the EM1{sub 1} considering the relatively narrow dispersion and high emission rate. This study showed that even though an area may be located within the same radius around the Kori Nuclear Power Plant, the distribution and levels of {sup 137}Cs concentration vary according to the change in time and space of weather conditions (the altitude of the atmospheric boundary layer, the horizontal and vertical distribution of the local winds, and the precipitation levels), the topography of the regions where {sup 137}Cs is dispersed, the emission rate of {sup 137}Cs, and the number of emitted particles.

    Full Text Available Fungi belonging to the genus Tuber establish ectomycorrhizal symbioses with shrubs, trees and some herbaceous plants. Some Tuber species, for example, T. melanosporum, T. magnatum, T. aestivum are economically important because they produce edible fruiting bodies with a distinctive taste and flavor. Our concept of truffle ecophysiology is dominated by the symbiosis with deciduous hosts, such as: Quercus spp., Fagus sylvatica, Castanea sativa, Corylus spp., Carpinus betulus, Ostrya carpinifolia, Betula verrucosa, and Tilia spp., whereas the real range of hosts in nature seems to be much wider. Moreover, interactions between Tuber mycelium and plant community could be more complex than just forming the ectomycorrhizal symbiosis. Here we show our inventory of plants and soils at six truffle’ sites in the southern part of Poland (Nida Basin and Przedbórz Upland. The aim of this study was to widen our understanding of ecological factors affecting Tuber spp., in the context of pioneering stage of research on truffles in Poland. We hope our findings will have a practical application and will help to choose suitable soils for truffle orchards.

    Experience is described gained with the application of computer code VELASCO in calculating the velocity field in fast reactor fuel assemblies taking into account configuration disturbances due to fuel pin displacement. Theoretical results are compared with the results of experiments conducted by UJV on aerodynamic models HEM-1 (model of the fuel assembly central part) and HEM-2 (model of the fuel assembly peripheral part). The results are reported of calculating the distribution of shear stress in wetted rod surfaces and in the assembly wall (model HEM-2) and the corresponding experimental results are shown. The shear stress distribution in wetted surfaces obtained using the VELASCO code allowed forming an opinion on the code capability of comprising local parameters of turbulent flow through a fuel rod bundle. The applicability was also tested of the code for calculating mean velocities in the individual zones, eg., in elementary cells. (B.S.)

    2016-06-01

    Full Text Available The aim of this paper is to highlight how hospitals, in Catalonia since the late Middle Ages to the currently, adopted a governance model which resulted in the creation and preservation of hospitals or care institutions in virtually all municipalities, even in small, whose frame legal was the private or civil law. Firstly, we observed how individuals were motivated not only by philanthropy or charity, but also by a need to contribute something to the community after their death, to give back part of the assets the testators had accumulated during their lifetimes, as citizens who had benefited from their positions. Secondly, we observed that the small local private institutions merged with municipal hospitals, but that their assets were managed separately from those of the town. Third, as well as its care function, the hospital was also an economic agent that operated along similar lines to the Italian “Monte dei Paschi”. It provided loans to working class citizens at a modest rate of interest. The meaning of the institution was found to be more complex than the simple provision of care services. It acquired a specific value in the identity of the community, it became one of the centers of debate in public life and it took on an economic and financial meaning that strengthened the construction of the citizens’ collective identity.Los hospitales, en Cataluña, se inscribieron desde la Baja Edad Media hasta nuestros días dentro un modelo de gobierno específico que dio lugar a la creación y mantenimiento de una densa red de instituciones asistenciales en prácticamente todos los municipios, incluso en los más pequeños, cuyo marco legal fue el derecho privado o civil. Dicho modelo tiene sus fundamentos, en primer lugar, en la constatación de cómo los individuos legaban al hospital no sólo por la filantropía o caridad, sino también por la necesidad de aportar algo a la comunidad después de su muerte, en una suerte de consigna con el

    In this work, the ecological, economical and social effects of uranium mining activity on environment and local communities in Caras Severin county are considered. 4412 radiochemical analyses and about 6730 radiometric measurements were made. The waters of local rivers were found to be contaminated with natural uranium and 226 radium, but the biological risk is not significant. Their concentrations and effective doses are presented in 8 tables referring to the rivers Lisava, Jitin, Caras. Also, samples of water from springs and wells in the Banat mining area were analysed for natural uranium and 226 Ra, their concentrations being found under the maximum permissible level. The air quality was not affected by accidental radon emissions. In order to limit the ecological impact on the environment, remedial action measures are proposed. The economic and social impact on the local communities are due mainly to the decline of activity, the most important effect being the unemployment

    A significant characteristics of the present situation of the Moldavian economy is the social impact of cyclic and structural economic crises. The energy crisis is an important concern for social-political background of the Republic and it requires updating the elements of the permanent capital implied in electrothermal power production. Comparative calculations were done for electrothermal demands and the results illustrate the dynamics of the energy intensity for the power output. Several suggestions are advanced to settle the energy-economical problems

    Full Text Available Street-connected youth are a neglected and vulnerable population, particularly in resource-constrained settings. The development of interventions and supports for this population requires insight into how they live. This study describes the social and economic characteristics of a convenience sample of street youth (SY in Eldoret, Kenya.Participants were eligible if they were aged 12-21, living in Eldoret, spending days only (part-time, or nights and days on the street (full-time and able and willing to consent or assent. Data were collected using a standardized interview conducted in English or Kiswahili. Binary dependent variables were having been arrested and/or jailed, and first priority for spending money (food vs. other. Nominal categorical dependent variables included major source of support, and major reason for being street-involved. Multivariable analysis used logistic regression models to examine the association of gender and level of street-involvement with social and economic factors of interest adjusting for age and length of time on the street. Data were analyzed using SAS 9.3.Of the 200 SY enrolled, 41% were female, mean age of 16.3 years; 71% were on the street full-time, and 29% part-time. Compared with part-time SY, full-time SY were more likely to have been arrested (Adjusted Odds Ratio [AOR]: 2.33, 95% Confidence Interval [95%CI]:1.01-5.35, name food as their first spending priority (AOR: 2.57, 95%CI:1.03-6.45, have left home due to violence (AOR: 5.54, 95%CI: 1.67-18.34, and more likely to report friends on the street as a major source of support (AOR: 3.59, 95% CI: 1.01-12.82. Compared with females, males were more likely to have ever been arrested (AOR: 2.66, 95%CI:1.14-6.18, and to have ever been jailed (AOR: 3.22, 95%CI:1.47-7.02.These results suggest a high degree of heterogeneity and vulnerability among SY in this setting. There is an urgent need for interventions taking into consideration these characteristics.

    Concrete is one of the most important materials used for radiation shielding in facilities containing radioactive sources and radiation generating machines. The concrete shielding properties may vary depending on the composite of the concrete. Aggregates is the largest constituent (about 70-80% of the total weight of normal concrete). The aim of this work is to develop special concrete with good shielding properties for gamma and neutrons, using natural local materials. For this reason two types of typical concrete widely used in Syria (in Damascus and Aleppo) and four other types of concrete, using aggregates from different regions, have been prepared. The shielding properties of these six types were studied for gamma ray (from Cs-137 and Co-60 sources)and for neutrons (from am-Be source). A reduction of about 10% in the HVL was obtained for the concrete from Damascus in comparison with that from Aleppo, for both neutrons and gammas. One of the other four types of concrete (from Rajo site, mostly Hematite), was found to further reduce the HVL by about 10% for both neutrons and gamma rays.(author)

    2010-01-01

    Dimensional restrictions in electronic equipment have resulted in miniaturization of many existing cooling technologies. In addition to this, cooling solutions are required to dissipate increased thermal loads to maintain component reliability. Axial fans are widely used in electronics cooling to meet such thermal demands. However, if the extent of non-uniform heat transfer rates, produced by highly three-dimensional air patterns is unknown in the design stages, premature component failure may result. The current study highlights these non-uniformities in heat transfer coefficient, using infrared thermography of a miniature axial fan impinging air on a flat plate. Fan rotational speed and distance from the flat plate are varied to encompass heat transfer phenomena resultant from complex exit air flow distribution. Local peaks in heat transfer coefficient have been shown to be directly related to the air flow and fan motor support interaction. Optimum locations for discrete heat source positioning have been identified which are a function of fan to plate spacing and independent of fan rotational speed when the Reynolds number effect is not apparent.

    To describe the prevalence of the cultivable subgingival microbiota in periodontal diseases and to draw attention to the polymicrobial nature of periodontic infections. The study population consisted of 95 patients, 51 females and 44 males, aged 14-62 years. Twenty-nine patients exhibited adult periodontitis (AP), six localized juvenile periodontitis (LJP), and 60 rapidly progressive periodontitis (RPP). Two to four pooled bacterial samples were obtained from each patient. Samples were collected with sterile paper points from the deepest periodontal pockets. The samples were cultured under anaerobic and microaerophilic conditions using selective and non-selective media. Isolates were characterized to species level by conventional biochemical tests and by a commercial rapid test system. Prevotella intermedia and Capnocytophaga spp. were the most frequently detected microorganisms in all diagnostic groups. Porphyromonas gingivalis and Peptostreptococcus micros were found more frequently in AP and RPP patients, while Actinobacillus actinomycetemcomitans and Eikenella corrodens were associated with AP, LJP and RPP patients. The other bacterial species, including Actinomyces spp., Streptococcus spp. and Eubacterium spp., were detected at different levels in the three disease groups. The data show the complexity of the subgingival microbiota associated with different periodontal disease groups, indicating that the detection frequency and levels of recovery of some periodontal pathogens are different in teeth affected by different forms of periodontal disease.

    Marais des Baux are located between Alpilles in the North and the plain of the Crau (South-East) of the town of Arles, in the South of France. Already built in Roman times, swamps located at the outlet of the Baux valley basin have experienced an increased human pressure during last centuries. Apotheosis of human development is the period of post-war with Marshall Plan and the development of the Common Agricultural Policy (CAP). At the beginning of the 21st century, inverse hydrologic dynamic is observed. Renaturation of the lower parts of the marshes, where land is less profitable, has reversed the trend of previous centuries. To be sustainable, this annealing must be accompanied by water governance at the watershed scale. This work aims to help policy makers and managers to good governance of the territory. Hierarchical multi-scale approach has enabled a better understanding of hydrological flows. In addition, knowledge of different actors' strategies is not enough. There may be different interests and strategies within the same group of actors. In this case, this is what we observe between farmers located on the upstream parts of the watershed eager, for some, to increase irrigation, and those located downstream, in the marshes, forced pump to maintain water levels corresponding to the expectations of the majority of the actors. On the other hand, there is a negative image of still marsh near a rural population and new rural population. Decreasing pumping or to send a higher volume of water could significantly increase flooded areas. This increase in flooded areas could facilitate the development of certain mosquito species. These mosquitoes not only represent a potential health risk for human populations but also increase the discomfort felt by the local population and tourists. This discomfort may also have an impact on economic activity linked with tourism. The work allowed the testing of different scenarios of flooding, according to the hydraulic management

    This paper is to experimentally and numerically investigate the cell performance and the localized characteristics associated with a high-temperature proton exchange membrane fuel cell (PEMFC). Three experiments are carried out in order to study the performance of the PEMFC with different operating conditions and to validate the numerical simulation model. The model proposed herein is a three-dimensional (3-D) computational fluid dynamics (CFD) non-isothermal model that essentially consists of thermal-hydraulic equations and electrochemical model. The performance curves of the PEMFC predicted by the present model agree with the experimental measured data. In addition, both the experiments and the predictions precisely demonstrate the enhanced effects of inlet gas temperature and system pressure on the PEMFC performance. Based on the simulation results, the localized characteristics within a PEMFC can be reasonably captured. These parameters include the fuel gas distribution, liquid water saturation distribution, membrane conductivity distribution, temperature variation, and current density distribution etc. As the PEMFC is operated at the higher current density, the fuel gas would be insufficiently supplied to the catalyst layer, consequently causing the decline in the generation of power density. This phenomenon is so called mass transfer limitation, which can be precisely simulated by the present CFD model.

  13. Participatory Approach to Long-Term Socio-Economic Scenarios as Building Block of a Local Vulnerability and Risk Assessment Tool - The Case Study Lienz (East-Tyrol)

    Risks associated with climate change are mostly still understood and analyzed in a sector- or hazard-specific and rarely in a systemic, dynamic and scenario-based manner. In addition, socio-economic trends are often neglected in local vulnerability and risk assessments although they represent potential key determinants of risk and vulnerability. The project ARISE (Adaptation and Decision Support via Risk Management Through Local Burning Embers) aims at filling this gap by applying a participatory approach to socio-economic scenario building as building block of a local vulnerability assessment and risk management tool. Overall, ARISE aims at developing a decision support system for climate-sensitive iterative risk management as a key adaptation tool for the local level using Lienz in the East-Tyrol as a test-site City. One central building block is participatory socio-economic scenario building that - together with regionalized climate change scenarios - form a centrepiece in the process-oriented assessment of climate change risks and vulnerability. Major vulnerabilities and risks may stem from the economic performance, the socio-economic or socio-demographic developments or changes in asset exposition and not from climate change impacts themselves. The IPCC 5th assessment report underlines this and states that for most economic sectors, the impact of climate change may be small relative to the impacts of other driving forces such as changes in population growth, age, income, technology, relative prices, lifestyle, regulation, governance and many other factors in the socio-economy (Arent et al., 2014). The paper presents the methodology, process and results with respect to the building of long-term local socio-economic scenarios for the City of Lienz and the surrounding countryside. Scenarios were developed in a participatory approach using a scenario workshop that involved major stakeholders from the region. Participatory approaches are increasingly recognized as

Multiple Correspondence Analysis was used in conjunction with SPAD 3.5 software, followed by hypothesis testing. The variables "pharmacist presence" and "population" were those which most contributed to the formation of the three clusters of municipalities observed. The number of drugs contained in the Municipal Lists of Essential Drugs (REMUMEs ranged from 15 to 413. A total of 67 towns had between 101 and 200 drugs- a range considered ideal in this study according to the 2006 National List of Essential Drugs. No tendency toward correlation between number of drugs listed in the REMUMES and municipality population size was found. Results confirmed the known disparity in Pharmaceutical Assistance among municipalities of different sizes and highlighted the need for structuring the activities of Pharmaceutical Assistance in the municipalities studied. There is also a need for greater commitment from all management spheres so that activities of Pharmaceutical Assistance at a local level ensure access to quality drugs and services, while fostering rational use.Este estudo retrata a etapa de diagnóstico de 201 Planos Municipais de Assistência Farmacêutica enviados entre 12 de novembro de 2005 a 06 de julho de 2006 à Diretoria de Assistência Farmacêutica da Secretaria de Estado da Saúde de Santa Catarina (DIAF-SES/SC.

    Heos 2 plasma and magnetic field measurements in the distant polar cusp region reveal the existence of a plasma layer on day side field lines just inside the magnetopause. Density and temperature in this layer are nearly the same as they are in the adjacent magnetosheath, but the flow lacks the order existing both in the magnetosheath and in the plasma mantle. Flow directions toward and away from the sun but, in general, parallel to the field lines have been found. The magnetopause (as defined by a sudden rotation of the magnetic field vector) mostly coincides with the transition to ordered magnetosheath flow. The inner boundary of the layer is located just within the outer boundary of the hot ring current plasma. In the region of overlap the hot electrons have the signature of trapped particles, though often at reduced intensity. The magnetic field is strongly fluctuating in magnitude, while its orientation is more stable, consistent with a connection to the earth, but is systematically distorted out of the meridian plane. The layer is thought to be a consequence of the entry of magnetosheath plasma, which does not appear to be unobstructed, as has been claimed in the concept of a magnetospheric cleft. The magnetopause has a cusplike indentation which is elongated in local time. The existence of field-aligned currents (total strength approx. =10 6 A) and their location of flow in the inner part of the entry layer (into the ionosphere before noon and out of it after noon) are inferred from the systematic bending of field lines. It is proposed that the dynamo of the related current system is provided by the transfer of perpendicular momentum resulting from the plasma entry into the layer. The essential features of the entry layer might be compatible with the model of plasma flow through the magnetopause of Levy et al. (1964) if a 'dam' effect caused by the cusp geometry were added

    2013-10-01

    Full Text Available The fall in public revenue by local governments, as a consequence of the finance dependence on the real estate sector, is combined with a process of fiscal adjustment and a growing demand for social services, which is result of rising socioeconomic exclusion rates (less consumption, business closures, and unemployment. The economic crisis, accompanied by a crisis of ethics and values, refers to the emergence of the Public Ethics as a tool for social policy-making and institutional strengthening. The incessant search for legitimacy and consensus, not so much in relation to the output of public social policies, but also about the dialog and deliberative process itself, puts local entities facing the challenges in the strengthening of the political body as a prerequisite for commissioning and developing successful participatory and deliberative processes. The promotion of socio-economic conditions to ensure social cohesion, freedom and equal opportunities, become a challenge that transcends the literalness and urgency of financial statements and budget processes in a fiscal adjustment context. The article reviews the main trends and challenges related to the role of Public Ethics in making public policy budget, citizen participation and social inclusion by local governments. All this, in a context of economic crisis, progressive social weakening, fiscal adjustment of the local public sector, public distrust for the institutions and growing axiological pluralism that is taken into account.

    In some arid land, the irrigated fields are not contiguous and are surrounded by large patches of bare land. During the summer time and rainless season, the solar radiation flux is high and the surface temperature during daylight in the dry bare areas, is much higher than that of the air. The sensible heat generated over these areas may be advected to the irrigated fields. The crops are usually planted in rows and the irrigation systems used (trickle) do not wet the whole surface, the dry bare soil between the rows may develop high soil surface temperatures and lead to convective activity inside the canopy above the bare soil. Advection from the surrounding fields and convective activity inside the canopy affect the layer above the crop. We studied the surface layer above an irrigated tomato field planted in Israel's Negev desert. The crop was planted in rows, trickle irrigated and the distance between the outer edges of two adjacent rows was 0.36 m at the time of measurement. The gradients in temperature and water vapor pressure were obtained at various heights above the canopy using a Bowen ratio machine. The residual in the energy balance equation was used as a criterion to determine the equilibrium layer. During the morning, unstable conditions prevail, and the equilibrium layer was between Z/h {approx} 1.9 and 2.4. In some particular circumstances, in the late morning, the bare soil between the rows reached extremely high temperatures and during conditions with low wind speeds free convection was identified. During these hours the residuals of the energy budget to the heights Z/h = 1.5 and 2.4 were significantly different from zero and an extremely large variability was evident for the Z/h = 3.2 layer. Local advection took place during the afternoon resulting in an increase in the stability of the uppermost measured layer and propagated slowly downwards. The equilibrium layer was between Z/h {approx} 1.5 to 2.4. The residuals were significantly different

    In many countries, there is a surplus of physicians in some communities and a shortage in others. Population size is known to be correlated with the number of physicians in a community, and is conventionally considered to represent the power of communities to attract physicians. However, associations between other demographic/economic variables and the number of physicians in a community have not been fully evaluated. This study seeks other parameters that correlate with the physician population and show which characteristics of a community determine its "attractiveness" to physicians. Associations between the number of physicians and selected demographic/economic/life-related variables of all of Japan's 3132 municipalities were examined. In order to exclude the confounding effect of community size, correlations between the physician-to-population ratio and other variable-to-population ratios or variable-to-area ratios were evaluated with simple correlation and multiple regression analyses. The equity of physician distribution against each variable was evaluated by the orenz curve and Gini index. Among the 21 variables selected, the service industry workers-to-population ratio (0.543), commercial land price (0.527), sales of goods per person (0.472), and daytime population density (0.451) were better correlated with the physician-to-population ratio than was population density (0.409).

    It is unclear why rates of homelessness claims in England have risen since 2010. We used variations in rates across local authorities to test the impact of economic downturns and budget cuts. Using cross-area fixed effects models of data from 323 UK local authorities between 2004 and 2012, we evaluated associations of changes in statutory homelessness rates with economic activity (Gross Value Added per capita), unemployment, and local and central government expenditure. Each 10% fall in economic activity was associated with an increase of 0.45 homelessness claims per 1000 households (95% CI: 0.10-0.80). Increasing rates of homelessness were also strongly linked with government reductions in welfare spending. Disaggregating types of welfare expenditure, we found that strongest associations with reduced homelessness claims were spending on social care, housing services, discretionary housing payments and income support for older persons. Recession and austerity measures are associated with significant increases in rates of homelessness assistance. These findings likely understate the full burden of homelessness as they only capture those who seek aid. Future research is needed to investigate what is happening to vulnerable groups who may not obtain assistance, including those with mental health problems and rough sleepers. © The Author 2015.

    The issue of street children is one of the global social problems rising in low- and middle-income countries. These children are vulnerable, but because of a lack of sufficient information, it is very difficult for stakeholders to address their plight in Cameroon. To examine the situation and characteristics of street children in three Cameroonian cities. To describe the demographic, socio-economic and behavioural profiles of street children. To identify challenges of street children and to compare the results from the three cities on account of their different settings, cultural history and challenges. The study was an analytical cross-sectional survey conducted through researcher-administered questionnaires to 399 street children (homeless for at least a month), in three Cameroonian cities from 1 January 2015 to 30 March 2015. The majority of the participants were boys, more than 70% were homeless for less than 12 months and poverty was found to be the most common reason for being on the street. Most of the participants earned less than 500CFA francs (USD 0.85), with many of them resorting to begging, drug abuse, sex work and other risky behaviours. Only two of the respondents (0.5%) regarded the public attitude towards them as supportive. As children roam the streets in search of shelter, food and other basic needs, their future hangs in the balance. Understanding the plight of street children highlights the need for immediate design and implementation of intervention strategies to prevent children from living in the streets and assist those who have become street children.

    Full Text Available With the incorporation of an automated fare-collection system into the management of public transportation, not only can the quality of transportation services be improved but also that of the data collected from users when coupled with smart-card technology. The data collected from smart cards provide opportunities for researchers to analyze big data sets and draw meaningful information out of them. This study aims to identify the relationship between travel patterns derived from smart-card data and urban characteristics. Using seven-day transit smart-card data from the public-transportation system in Seoul, the capital city of the Republic of Korea, we investigated the temporal and spatial boarding and alighting patterns of the users. The major travel patterns, classified into five clusters, were identified by utilizing the K-Spectral Centroid clustering method. We found that the temporal pattern of urban mobility reflects daily activities in the urban area and that the spatial pattern of the five clusters classified by travel patterns was closely related to urban structure and urban function; that is, local environmental characteristics extracted from land-use and census data. This study confirmed that the travel patterns at the citywide level can be used to understand the dynamics of the urban population and the urban spatial structure. We believe that this study will provide valuable information about general patterns, which represent the possibility of finding travel patterns from individuals and urban spatial traits.

    School meals are an important state-delivered mechanism for improving children's diets. Scottish local authorities have a statutory duty to provide free school meals (FSM) to families meeting means-testing criteria. Inevitably take-up of FSM does not reach 100%. Explanations put forward to explain this include social stigma, as well as a more general dissatisfaction amongst pupils about lack of modern facilities and meal quality, and a preference to eat where friends are eating. This study investigated characteristics associated with take-up across Scottish secondary schools in 2013-2014 using multilevel modelling techniques. Results suggest that stigma, food quality and the ability to eat with friends are associated with greater take-up. Levels of school modernisation appeared less important, as did differences between more urban or rural areas. Future studies should focus on additional school-level variables to identify characteristics associated with take-up, with the aim of reducing the number of registered pupils not taking-up FSM.

    Full Text Available Abstract Introduction Equitable access to health care is a key health systems goal, and is a particular concern in low-income countries. In Kenya, public facilities are an important resource for the poor, but little is known on the equity of service provision. This paper assesses whether poorer areas have poorer health services by investigating associations between public facility characteristics and the poverty level of the area in which the facility is located. Methods Data on facility characteristics were collected from a nationally representative sample of public health centers and dispensaries across all 8 provinces in Kenya. A two-stage cluster randomized sampling process was used to select facilities. Univariate associations between facility characteristics and socioeconomic status (SES of the area in which the facility was located were assessed using chi-squared tests, equity ratios and concentration indices. Indirectly standardized concentration indices were used to assess the influence of SES on facility inputs and service availability while controlling for facility type, province, and remoteness. Results For most indicators, we found no indication of variation by SES. The clear exceptions were electricity and laboratory services which showed evidence of pro-rich inequalities, with equity ratios of 3.16 and 3.43, concentration indices of 0.09 (p Conclusions The paper shows how local area poverty data can be combined with national health facility surveys, providing a tool for policy makers to assess the equity of input and service availability. There was little evidence of inequalities for most inputs and services, with the clear exceptions of electricity and laboratory services. However, efforts are required to improve the availability of key inputs and services across public facilities in all areas, regardless of SES.

Studies performed by the Center for Health Incentives and Behavioral Economics at the University of Pennsylvania published between January 2006 and March 2014. Randomized, controlled trials with available participant-level data. Studies that did not use financial incentives to promote health behavior change were excluded. Participant-level data from seven studies were pooled. Meta-analysis on the pooled sample using a random-effects model with interaction terms to examine treatment effects and whether they varied by incentive structure or demographic characteristics. The pooled study sample comprised 1403 participants, of whom 35% were female, 70% were white, 24% were black, and the mean age was 48 years (standard deviation 11.2 years). In the fully adjusted model, participants offered financial incentives had higher odds of behavior change (odds ratio [OR]: 3.96; p financial incentives and gender, age, race, income, or education. When further adjusting for incentive structure, blacks had higher odds than whites of achieving behavior change (OR: 1.67; p Financial incentives designed using concepts from behavioral economics were effective for promoting health behavior change. There were no large and consistent relationships between the effectiveness of financial incentives and observable demographic characteristics. Second-order examinations of incentive structure suggest potential relationships among the effectiveness of financial incentives, incentive structure, and the demographic characteristics of race and income.

    We investigated whether or not changes in economic conditions during the 2008-2010 U.S. recession were associated with changes in Connecticut local health jurisdictions' (LHJs') revenue or personnel levels. We analyzed Connecticut Department of Public Health 2005-2012 annual report data from 91 Connecticut LHJs, as well as publicly available data on economic conditions. We used fixed- and random-effect regression models to test whether or not LHJ per capita revenues and full-time equivalent (FTE) personnel differed during and post-recession compared with pre-recession, or varied with recession intensity, as measured by unemployment rates and housing permits. On average, total revenue per capita was significantly lower during and post-recession compared with pre-recession, with two-thirds of LHJs experiencing per capita revenue reductions. FTE personnel per capita were significantly lower post-recession. Changes in LHJ-level unemployment rates and housing permits did not explain the variation in revenue or FTE personnel per capita. Revenue and personnel differed significantly by LHJ organizational structure across all time periods. Economic downturns can substantially reduce resources available for local public health. LHJ organizational structure influences revenue levels and sources, with implications for the scope, quality, and efficiency of services delivered.

    Full Text Available Lack of good drinking water due to contamination by chemicals has been a global menace. It is one of the most serious environmental problems that have greatly impacted human health. Basic quality parameters of domestic water sources in Ebonyi Local Government Area were studied in the months of September 2014 and October 2014. Samples were randomly collected from common water sources well stream borehole and pond across four communities in the Local Government Area. The physicochemical characteristics of the collected water samples were investigated using standard procedures. The results showed mean pH values of 7.3 7.8 6.8 and 7.0 for well stream borehole and pond water samples respectively. The colour examination showed 13 HU 11 HU 13 HU and 16 HU for well stream borehole and pond water samples respectively. The turbidity were recorded as 103 NTU well 90 NTU stream 0.8 NTU borehole and 92 NTU pond. Total dissolved solids TDS showed a record of 595 mgL 386mgL 76 mgL and 563 mgL for well stream borehole and pond respectively. Well water recorded 78 mgL stream 112 mgL borehole 42 mgL and pond 795 mgL for Total Suspended Solids respectively. Also the total hardness showed 525 mgL 779 mgL 44 mgL and 837 mgL for well stream borehole and pond water samples respectively. The results show that most of the common sources of water in the studied areas are not good for drinking since the physicochemical variables evaluated mostly exceeded WHO permissible limits. We therefore recommend that water treatment should be paramount as alternative sources of drinking water in the communities should be considered.

The purpose of this study was to compare clinicopathological characteristics and outcomes between inflammatory and non-inflammatory LABC patients at Breast Cancer Research Center (BCRC, Tehran, Iran.Methods: The medical records of all patients who were diagnosed as LABC in BCRC  since  1997  to  2011  were  extracted  from  the database. Then,  clinical  and pathological characteristics and overall survival of IBC patients were compared with non-inflammatory LABC (NI-LABC.Results: A total number of 340 patients were identified as LABC from which 17 patients (5% were diagnosed as IBC. Menopausal status, body mass index (BMI, family history of breast cancer, nodal status, and Her2/neu and PR positivity were not statistically different between IBC and NI-LABC groups. The difference in estrogen receptor (ER between the two groups was significant (P = 0.028. Median duration of follow-up was 26.50 months. Patients with IBC had overall survival of 27.9 months (95% CI: 22.7–33.1 which was lower than patients in the NI-LABC group with a survival of 118.9 months (95% CI: 107.3–130.6 (P = 0.015. The difference between the disease-free survivals of the two groups were also statistically significant (P < 0.001.Conclusions: Compared to NI-LABC, IBC is more frequently ER negative and more commonly associated with lower survival rate. These findings reinforce the idea that IBC has a more aggressive biology and more unfavorable outcome than NI-LABC and needs close follow-up. Normal 0 false false false EN-US X-NONE X-NONE

    2010-01-01

    In economic sociology, Bourdieu’s neo-capital theory (Bourdieu, 1986) has regularly been applied by sociologists, who reject the rational action theory (Anheier et al., 1995). However, we claim that Bourdieu’s key finding that forms of tangible and intangible capital (e.g. physical, economic......, social, symbolic) are being perpetually accumulated and converted by individuals can best be explained within a rational action framework. This framework should be seen as modified by specific social structures (Coleman, 1988) and, hence, characterized by uncertainty and risky investments....... Methodologically, we think that the ‘laws of conversion’ (Bourdieu, 1986:252-255) can best be observed at the micro level, by analyzing specific strings of capital conversion in time and space. Therefore, drawing on in-depth interviews with four private entrepreneurs in rural Denmark we try to analyze rational...

  20. Tuning characteristic of band gap and waveguide in a multi-stub locally resonant phononic crystal plate

    Xiao-Peng Wang

    2015-10-01

    Full Text Available In this paper, the tuning characteristics of band gaps and waveguides in a locally resonant phononic crystal structure, consisting of multiple square stubs deposited on a thin homogeneous plate, are investigated. Using the finite element method and supercell technique, the dispersion relationships and power transmission spectra of those structures are calculated. In contrast to a system of one square stub, systems of multiple square stubs show wide band gaps at lower frequencies and an increased quantity of band gaps at higher frequencies. The vibration modes of the band gap edges are analyzed to clarify the mechanism of the generation of the lowest band gap. Additionally, the influence of the stubs arrangement on the band gaps in multi-stub systems is investigated. The arrangements of the stubs were found to influence the band gaps; this is critical to understand for practical applications. Based on this finding, a novel method to form defect scatterers by changing the arrangement of square stubs in a multi-stub perfect phononic crystal plate was developed. Defect bands can be induced by creating defects inside the original complete band gaps. The frequency can then be tuned by changing the defect scatterers’ stub arrangement. These results will help in fabricating devices such as acoustic filters and waveguides whose band frequency can be modulated.

    As the body of evidence linking disparities in the health of urban residents to disparate social, economic and environmental contexts grows, efforts to delineate the pathways through which broader social and economic inequalities influence health have burgeoned. One hypothesized pathway connects economic and racial and ethnic inequalities to differentials in stress associated with social and physical environments, with subsequent implications for health. Drawing on data from Detroit, Michigan, we examined contributions of neighborhood-level characteristics (e.g., poverty rate, racial and ethnic composition, residential stability) and individual-level characteristics (e.g., age, gender) to perceived social and physical environmental stress. We found that neighborhood percent African American was positively associated with perceptions of both social and physical environmental stress; neighborhood percent poverty and percent Latino were positively associated with perceived physical environmental stress; and neighborhood residential stability was negatively associated with perceived social environmental stress. At the individual level, whites perceived higher levels of both social and physical environmental stress compared to African American residents of the same block groups, after accounting for other variables included in the models. Our findings suggest the importance of understanding and addressing contributions of neighborhood structural characteristics to perceptions of neighborhood stress. The consistency of the finding that neighborhood racial composition and individual-level race influence perceptions of both social and physical environments suggests the continuing importance of understanding the role played by structural conditions and by personal and collective histories that vary systematically by race and ethnicity within the United States.

    This paper explores possible interdependence of biodiversity and several socioeconomic and political factors at the county level. It is aimed at the empirical identification of direct and indirect effects between biodiversity (loss) and their theoretical major impact factors. To date, research...... is related to the fact that cropland farming seems to be less profitable in this low-yield areas. 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 impact...

    The cogeneration is the combined production of electric and/or mechanical and thermal energy starting by a single energy source; in particular in this paper the analysis will be focused on a cogeneration system with electric power lower than 15 kW (micro-cogeneration). The paper analyzes a system consisting of a natural gas-fired micro-cogeneration unit (MCHP), a heat storage and a peak boiler. The system provides thermal and electric energy to two end-users, the former is a tertiary building (office), where the generation system is located, and the latter is a residential building connected to the former through a district heating micro-grid. In order to analyze the influence of climatic conditions, two different geographical locations in Italy (Benevento and Milano) are considered, that are also characterized by different natural gas and electricity tariffs. Particular attention is paid to the choice of the users, in order to obtain more stable and continuous electric and thermal loads (load sharing approach) and to increase the operating hours per year of the MCHP unit. The operation of the MCHP is governed by a control system, aimed to optimize a thermo-economic objective function. The models representing the components, the thermo-economic objective function and the buildings have been implemented in a widely used commercial software for building simulations. The models are calibrated and validated through data obtained from experimental tests carried out in the laboratory of the University of Sannio (Benevento). The results of the simulations highlight the potential benefits of the thermal load sharing approach. In particular, this study shows that an MCHP unit connected by means of a thermal micro-grid to different users in “load sharing mode” can obtain a high number of operating hours as well as significant energy (Primary Energy Saving) and environmental (avoided CO 2 equivalent emissions) benefits with respect to an appropriate reference system

    SRS was established in 1951 as a nuclear materials production facility; however, decline in the defense mission budget at SRS has created a major economic impact on the community in the Central Savannah River Area. SRS has been offsetting these effects by producing revenue (80 million dollars to date) from the sale of forest products since 1955 primarily trees, but also pine straw. Revenue has been re-invested into the infrastructure development, restoration and management of natural resources. Total asset value of the forest-land has increased from 21 million to over 500 million dollars in the same period

    This paper analyses the mathematical properties of an economic growth model with overlapping generations, endogenous labour supply, and multiplicative external habits. The dynamics of the economy is characterised by a two-dimensional map describing the time evolution of capital and labour supply. We show that if the relative importance of external habits in the utility function is sufficiently high, multiple (determinate or indeterminate) fixed points and poverty traps can exist. In addition, periodic or quasiperiodic behaviour and/or coexistence of attractors may occur.

    Literature shows that choice for unsafe abortion is often driven by poverty. However, factors related to the family formation behaviour of women are also implied as determinants of this decision. This study assessed which family formation characteristics of women are associated with the risk of unsafe abortion, without being confounded by their low socio-economic status among Sri Lankan women admitted to hospital following post-abortion complications. An unmatched case-control study was conducted in nine hospitals in eight districts in Sri Lanka among 171 women with post-abortion complications following unsafe abortion (Cases) and 600 postpartum mothers admitted to same hospitals during the same period for delivery of term unintended pregnancies (Controls). Interviewer-administered-questionnaires obtained demographic, socio-economic and family formation related characteristics. Risk factors of abortion were assessed by odds-ratio (OR), adjusted for their socio-economic status in logistic regression analysis. Low socio-economic status, characterised by low-education (adjusted OR = 1.5; 95 % CI = 1.1-2.4) and less/unskilled occupations (2.3; 1.4-3.6) was a significant risk factor for unsafe abortion. Independent of this risk, being unmarried (9.3; 4.0-21.6), failure in informed decisions about desired family size (2.2; 1.4-3.5), not having a girl-child (2.2; 1.4-3.4) and longer average birth intervals (0.7 years; 0.6-0.8) signified the vulnerability of women for unsafe abortion. Cases were as fast as the controls in their family completion (4.3 versus 4.5 years; p = 0.4), but were at increased risk for abortion, if their average birth intervals (including the last one) were longer. Previous contraceptive use, age at reproductive events or partners' characteristics did not impart any risk for abortion. Low socio-economic status is not the most influencing risk factor for unsafe abortions leading to complications, but many other factors in relation to

    This article records the traditional knowledge of crab gatherers in the city of Conde, in the North Coast Region of Bahia State, Northeastern Brazil. Data on biological and ecological aspects of economically important brachyuran crustaceans have been obtained from semi-structured interviews and in loco observations conducted from September 2007 to December 2009. A total of 57 fishermen of both genders, aged between 10 and 78 years have been interviewed (individually or collectively) in different contexts; interviewees were asked about aspects such as external morphology, life cycle, trophic ecology, and spatial and temporal distribution of the major economically important brachyuran crustaceans in the region. Seven fishing communities were visited: Siribinha, Sítio do Conde, Poças, Ilha das Ostras, Cobó, Buri and Sempre Viva. Data were analyzed by comparing the information provided by participants with those from the specialized academic literature. The results show that artisanal fishermen have a wide ranging and well-grounded knowledge on the ecological and biological aspects of crustaceans. Crab gatherers of Conde know about growth and reproductive behavior of the animals they interact with, especially with regard to the three major biological aspects: "molt", "walking dance" and "spawning". This knowledge constitutes an important source of information that should be considered in studies of management and sustainable use of fishery resources in the North Coast Region of Bahia State.

    The purpose of the analysis was to develop a health economic model to estimate the costs and health benefits of alternative National Health Service (NHS) service configurations for people with longer-term depression. Modelling methods were used to develop a conceptual and health economic model of the current configuration of services in Sheffield, England for people with longer-term depression. Data and assumptions were synthesised to estimate cost per Quality Adjusted Life Years (QALYs). Three service changes were developed and resulted in increased QALYs at increased cost. Versus current care, the incremental cost-effectiveness ratio (ICER) for a self-referral service was £11,378 per QALY. The ICER was £2,227 per QALY for the dropout reduction service and £223 per QALY for an increase in non-therapy services. These results were robust when compared to current cost-effectiveness thresholds and accounting for uncertainty. Cost-effective service improvements for longer-term depression have been identified. Also identified were limitations of the current evidence for the long term impact of services.

    To undertake an assessment of survey participation and non-response error in a population-based study that examined the relationship between socio-economic position and food purchasing behaviour. The study was conducted in Brisbane City (Australia) in 2000. The sample was selected using a stratified two-stage cluster design. Respondents were recruited using a range of strategies that attempted to maximise the involvement of persons from disadvantaged backgrounds: respondents were contacted by personal visit and data were collected using home-based face-to-face interviews; multiple call-backs on different days and at different times were used; and a financial gratuity was provided. Non-institutionalised residents of private dwellings located in 50 small areas that differed in their socio-economic characteristics. Rates of survey participation - measured by non-contacts, exclusions, dropped cases, response rates and completions - were similar across areas, suggesting that residents of socio-economically advantaged and disadvantaged areas were equally likely to be recruited. Individual-level analysis, however, showed that respondents and non-respondents differed significantly in their sociodemographic and food purchasing characteristics: non-respondents were older, less educated and exhibited different purchasing behaviours. Misclassification bias probably accounted for the inconsistent pattern of association between the area- and individual-level results. Estimates of bias due to non-response indicated that although respondents and non-respondents were qualitatively different, the magnitude of error associated with this differential was minimal. Socio-economic position measured at the individual level is a strong and consistent predictor of survey non-participation. Future studies that set out to examine the relationship between socio-economic position and diet need to adopt sampling strategies and data collection methods that maximise the likelihood of recruiting

    Many studies since 2004 have documented the dissemination and receipt of risk information for local to distant tsunamis and factors influencing people's responses. A few earlier tsunami studies and numerous studies of other hazards provide additional support for developing effective tsunami messages. This study explores evidence-based approaches to developing such messages for the Pacific and National Tsunami Warning Centers in the US. It extends a message metric developed for the NWS Tsunami Program. People at risk to tsunamis receive information from multiple sources through multiple channels. Sources are official and informal and environmental and social cues. Traditionally, official tsunami messages followed a linear dissemination path through relatively few channels from warning center to emergency management to public and media. However, the digital age has brought about a fundamental change in the dissemination and receipt of official and informal communications. Information is now disseminated in very non-linear paths and all end-user groups may receive the same message simultaneously. Research has demonstrated a range of factors that influence rapid respond to an initial real or perceived threat. Immediate response is less common than one involving delayed protective actions where people first engage in "milling behavior" to exchange information and confirm the warning before taking protective action. The most important message factors to achieve rapid response focus on the content and style of the message and the frequency of dissemination. Previously we developed a tsunami message metric consisting of 21 factors divided into message content and style and receiver characteristics. Initially, each factor was equally weighted to identify gaps, but here we extend the work by weighting specific factors. This utilizes recent research that identifies the most important determinants of protective action. We then discuss the prioritization of message information

    The integrity of structures buried in earthing becomes relevant when analysing maintenance and replacement costs of these systems, as the deterioration is mainly due to two factors, namely: the failures caused in the electrical systems, which are due to the system. Failure in earthing due to corrosion at the interface cause an alteration in the structure of the component material and generates an undesirable resistivity that cause malfunction in this type of protection systems. Two local soils were chosen that were categorized as sandy loam and clay loam type, whose chemical characteristics were simulated by means of an electrolyte corresponding to the amount of ions present determined by a soil characterization based on the CICE (effective cation exchange coefficient), which allows us to deduce the percentage of chloride and sulphate ions present for the different levels established in the experimental matrix. The interaction of these soils with grounding electrodes is a complex problem involving many factors to consider. In this study, the rates and corrosion currents of the different soils on two types of electrodes, one copper and the other AISI 304 stainless steel, were approximated by electrochemical techniques such as potentiodynamic curves and electrochemical impedance spectra. Considerably higher speeds were determined for copper-type electrodes when compared to those based on steel. However, from the Nyquist diagrams, it was noted that copper electrodes have better electrical performance than steel ones. The soil with the highest ionic activity turned out to be the sandy loam. The clay loam soil presents a tendency to water retention and this may be the reason for the different behaviour with respect to ionic mobility. The diffusion control in the steel seems to alter the ionic mobility because its corrosion rates proved to be very similar regardless of the type of soil chemistry. In general, corrosion rates fell since tenths of a millimetre every year to

    Full Text Available The impact of globalization in a worldwide scale is even more noticeable in the each country during period of world economic crisis due to the differences in the economic status, deformed by the crisis phenomena. In that case, the conflict between global tendencies and local manifestations in the regional aspect of economic phenomena is even more evidently noticeable as a direct reflection of the resource deficiency. The mineral resources are directly related to that process, not only as a first phase of the transformation of the raw material potential for each country, but also as a serious violator of the ecological equilibrium as a result of the applied technologies. Each country is enforced to resolve the various issues related to preserving the own resource potential as much as possible and to subordinate its investment and technological decisions to an integrated and in-depth utilization in compliance with the sustainable development of society

    Aspen Plus(®) based simulation models have been developed to design a pyrolysis process for on-site production and utilization of pyrolysis oil from equine waste at the Equine Rehabilitation Center at Morrisville State College (MSC). The results indicate that utilization of all the available waste from the site's 41 horses requires a 6 oven dry metric ton per day (ODMTPD) pyrolysis system but it will require a 15 ODMTPD system for waste generated by an additional 150 horses at the expanded area including the College and its vicinity. For this a dual fluidized bed combustion reduction integrated pyrolysis system (CRIPS) developed at USDA's Agricultural Research Service (ARS) was identified as the technology of choice for pyrolysis oil production. The Aspen Plus(®) model was further used to consider the combustion of the produced pyrolysis oil (bio-oil) in the existing boilers that generate hot water for space heating at the Equine Center. The model results show the potential for both the equine facility and the College to displace diesel fuel (fossil) with renewable pyrolysis oil and alleviate a costly waste disposal problem. We predict that all the heat required to operate the pyrolyzer could be supplied by non-condensable gas and about 40% of the biochar co-produced with bio-oil. Techno-economic Analysis shows neither design is economical at current market conditions; however the 15 ODMTPD CRIPS design would break even when diesel prices reach $11.40/gal. This can be further improved to $7.50/gal if the design capacity is maintained at 6 ODMTPD but operated at 4950 h per annum. Published by Elsevier Ltd.

    Purpose: To prospectively compare health-related quality of life (HRQOL), patient-reported treatment-related symptoms, and costs of iodine-125 permanent implant interstitial brachytherapy (IB) with those of radical prostatectomy (RP) during the first 2 years after these treatments for localized prostate cancer. Methods and Materials: A total of 435 men with localized low-risk prostate cancer, from 11 French hospitals, treated with IB (308) or RP (127), were offered to complete the European Organization for Research and Treatment of Cancer core Quality of Life Questionnaire QLQ-C30 version 3 (EORTC QLQ-C30) and the prostate cancer specific EORTC QLQ-PR25 module before and at the end of treatment, 2, 6, 12, 18, and 24 months after treatment. Repeated measures analysis of variance and analysis of covariance were conducted on HRQOL changes. Comparative cost analysis covered initial treatment, hospital follow-up, outpatient and production loss costs. Results: Just after treatment, the decrease of global HRQOL was less pronounced in the IB than in the RP group, with a 13.5 points difference (p < 0.0001). A difference slightly in favor of RP was observed 6 months after treatment (-7.5 points, p = 0.0164) and was maintained at 24 months (-8.2 points, p = 0.0379). Impotence and urinary incontinence were more pronounced after RP, whereas urinary frequency, urgency, and urination pain were more frequent after IB. Mean societal costs did not differ between IB ( Euro 8,019 at T24) and RP ( Euro 8,715 at T24, p = 0.0843) regardless of the period. Conclusions: This study suggests a similar cost profile in France for IB and RP but with different HRQOL and side effect profiles. Those findings may be used to tailor localized prostate cancer treatments to suit individual patients' needs

    Hemimegalencephaly is a well-known congenital malformation. However, localized megalencephaly, which may be one of the subtypes of hemimegalencephaly, has not been separately investigated. In the present study, we attempted to characterize the clinical and magnetic resonance (MR) imaging features of localized megalencephaly in comparison with ordinary diffuse hemimegalencephaly and multilobar cortical dysplasia. MR findings for 43 patients with hemimegalencephaly and ten with multilobar cortical dysplasia, which is the differential diagnosis of localized megalencephaly, were retrospectively reviewed. Clinical findings such as the onset and severity of seizures and imaging findings including the affected area of the brain, structures outside of the hemisphere, and interval morphological changes were examined. Of the 43 patients, 11 showed signs of localized megalencephaly (25.6%). Localized megalencephaly was predominantly seen on the left side (72.7%) and had a tendency toward severe-grade seizures compared to multilobar cortical dysplasia. The frequencies of the extracerebral abnormalities in the diffuse hemimegalencephaly, localized megalencephaly, and multilobar cortical dysplasia groups were 84.4%, 36.4%, and 0.0%, respectively. There were three localized megalencephaly patients whose affected areas shrank and whose images were similar to those of multilobar cortical dysplasia. Localized megalencephaly accounts for one quarter of all hemimegalencephaly cases in this study. The incidence of extracerebral abnormalities in patients with localized hemimegalencephaly was almost half that of patients with diffuse hemimegalencephaly. Extracerebral abnormalities were absent in patients with multilobar cortical dysplasia. Associated extracerebral abnormalities may be a clue to differentiating localized megalencephaly from multilobar cortical dysplasia. (orig.)

    To investigate whether exposure to fast-food outlets and supermarkets is socio-economically patterned in the city of Copenhagen. The study was based on a cross-sectional multivariate approach to examine the association between the number of fast-food outlets and supermarkets and neighbourhood-level socio-economic indicators. Food business addresses were obtained from commercial and public business locators and geocoded using a geographic information system for all neighbourhoods in the city of Copenhagen (n 400). The regression of counts of fast-food outlets and supermarkets v. indicators of socio-economic status (percentage of recent immigrants, percentage without a high-school diploma, percentage of the population under 35 years of age and average household income in Euros) was performed using negative binomial analysis. Copenhagen, Denmark. The unit of analysis was neighbourhood (n 400). In the fully adjusted models, income was not a significant predictor for supermarket exposure. However, neighbourhoods with low and mid-low income were associated with significantly fewer fast-food outlets. Using backwise deletion from the fully adjusted models, low income remained significantly associated with fast-food outlet exposure (rate ratio = 0·66-0·80) in the final model. In the city of Copenhagen, there was no evidence of spatial patterning of supermarkets by income. However, we detected a trend in the exposure to fast-food outlets, such that neighbourhoods in the lowest income quartile had fewer fast-food outlets than higher-income neighbourhoods. These findings have similarities with studies conducted in the UK, but not in the USA. The results suggest there may be socio-economic factors other than income associated with food exposure in Europe.

    Despite similar guidance by local electrogram criteria, catheter ablation of right-sided accessory atrioventricular (AV) pathways by radiofrequency current has been less effective than that of left-sided ones. In order to elucidate the possible diversities in local electrosignal criteria, we systematically analyzed the morphological and timing characteristics of 215 bipolar local electrograms from catheter ablation sites of 65 left-sided accessory AV pathways and of 356 from those of 37 right-sided ones in 92 consecutive patients with Wolff-Parkinson-White syndrome or AV reentrant tachycardia incorporating concealed accessory AV pathways. After stepwise multivariate analysis, we selected the presence of a possible accessory pathway potential, local ventricular activation preceding QRS complex for 20 ms or more during ventricular insertion mapping, and the local retrograde ventriculoatrial (VA) continuity, local retrograde VA interval right-sided targets only) during atrial insertion mapping, as independent local electrogram predictors for successful ablation of left- and right-sided accessory AV pathways. Combination of all local electrogram predictors could have moderate chance of success (80 and 51%) for the ventricular and atrial insertion ablation of left-sided accessory AV pathways, but only low probability of success (40% in ventricular insertion ablation) or very low sensitivity (12.5% in atrial insertion ablation) for right-sided ones. In conclusion, with the present approach, successful catheter ablation of right-sided accessory AV pathways, compared to left-sided ones, still necessitate a breakthrough in the precision mapping and the efficiency of energy delivery.

    Trans fatty acids (TFA) increase the risk of mortality and chronic diseases. TFA intakes have fallen since reformulation, but may still be high in certain, vulnerable, groups. This paper investigates socio-economic and food consumption characteristics of high TFA consumers after voluntary reformulation in the Netherlands and UK. Post-reformulation data of adults aged 19-64 was analysed in two national surveys: the Dutch National Food Consumption Survey (DNFCS) collected 2007-2010 using 2*24hr recalls (N = 1933) and the UK National Diet and Nutrition Survey (NDNS) years 3&4 collected 2010/11 and 2011/12 using 4-day food diaries (N = 848). The socio-economic and food consumption characteristics of the top 10% and remaining 90% TFA consumers were compared. Means of continuous data were compared using t-tests and categorical data means using chi-squared tests. Multivariate logistic regression models indicated which socio-demographic variables were associated with high TFA consumption. In the Dutch analyses, women and those born outside the Netherlands were more likely to be top 10% TFA consumers than men and Dutch-born. In the UK unadjusted analyses there was no significant trend in socio-economic characteristics between high and lower TFA consumers, but there were regional differences in the multivariate logistic regression analyses. In the Netherlands, high TFA consumers were more likely to be consumers of cakes, buns & pastries; cream; and fried potato than the remaining 90%. Whereas in the UK, high TFA consumers were more likely to be consumers of lamb; cheese; and dairy desserts and lower crisps and savoury snack consumers. Some socio-demographic differences between high and lower TFA consumers were evident post-reformulation. High TFA consumers in the Dutch 2007-10 survey appeared more likely to obtain TFA from artificial sources than those in the UK survey. Further analyses using more up-to-date food composition databases may be needed.

    Full Text Available Background: The issue of physical activity (PA is often addressed in the literature, but its socio-economic determinants are not fully recognized. To date no studies of the adult population of Katowice have been carried out. Research in this area is of great importance in the context of the documented influence of PA on health and extension of retirement age in Poland. The aim of this paper is to evaluate the relationship between PA and socio-economic status of adult residents of Katowice. Materials and Methods: The study carried out in 2010 comprised 2053 people (987 women and 1066 men aged 30-65 years. To evaluate PA in the study group the diagnostic survey method and a research tool in the form of an abridged version of the International Physical Activity Questionnaire (IPAQ, with specification expanded by the authors, were used. In the statistical analysis logistic regression was employed. Results: The likelihood of meeting the standards of health-enhancing PA was higher in men than in women, and it decreased with age and education level of the respondents. The highest proportion of those meeting the recommendation of health-enhancing PA was observed among blue-collar workers, operators, teachers, police and soldiers. The lowest probability of meeting the recommendations of the American College of Sports Medicine was found among economists and lawyers, office workers, the unemployed, managers, and engineers, pensioners and health care professionals. Conclusions: The study demonstrates the correlation between PA and socio-economic status of the respondents. The analysis of the results indicates the necessity to promote PA programs mainly among women, the elderly, the unemployed, pensioners and representatives of professions, such as economists, lawyers, managers, engineers, and health professionals.

    Industrial and agricultural activities can generate heavy metal pollution that can cause a number of negative environmental and health impacts. This means that evaluating heavy metal pollution and identifying the sources of these pollutants, especially in urban or developed areas, is an important first step in mitigating the effects of these contaminating but necessary economic activities. Here, we present the results of a heavy metal (Cu, Pb, Zn, Cd, As, and Hg) soil geochemical survey in Hefei city. We used a multifractal spectral technique to identify and compare the multifractality of heavy metal concentrations of soils within the industrial Daxing and agricultural Yicheng areas. This paper uses three multifractal parameters (Δα, Δf(α), and τ''(1)) to indicate the overall amount of multifractality within the soil geochemical data. The results show all of the elements barring Hg have larger Δα, Δf(α), and τ''(1) values in the Daxing area compared to the Yicheng area. The degree of multifractality suggests that the differing economic activities in Daxing and Yicheng generate very different heavy metal pollution loads. In addition, the industrial Daxing area contains significant Pb and Cd soil contamination, whereas Hg is the main heavy metal present in soils within the Yicheng area, indicating that differing clean-up procedures and approaches to remediating these polluted areas are needed. The results also indicate that multifractal modelling and the associated generation of multifractal parameters can be a useful approach in the evaluation of heavy metal pollution in soils.

    2011-01-01

    Full Text Available Ingermanland became a destination point for migrants of many nationalities and had an inner circulation of the domestic population in the 19th century. Migratory routes, as well as the outflow and inflow volumes in the region differed for each ethnic group. A micro-historical approach enables one to assess the various reasons for the mobility of the homogeneous domestic population. There was a specific migration of orphans to Lutheran Finnish communities. Indeed the main reason for this migration was due to economic factors. A structural change of employment in the case of the closure of factories resulted in the outward movement of the population, alongside the allure of higher wages in localities with an industrial and trade infrastructure. The expansion of St. Petersburgs city border led to complex migratory processes as a result of the rapid economic development of the capital region. Ingermanland became an important part of the international market exchange that created opportunities for migrants and businesses of residents affected by the changes, who increasingly gave up agricultural production and sought other ways of earning a livelihood.

    Growing self-generation and storage are expected to cause significant changes in residential electricity utilization patterns. Commonly applied volumetric network tariffs may induce imbalance between different groups of households and their respective contribution to recovering the operating costs of the grid. Understanding consumer behaviour and appliance usage together with socio-economic factors can help regulatory authorities to adapt network tariffs to new circumstances in a fair way. Here, we assess the effects of 11 network tariff scenarios on household budgets using real load profiles from 765 households. Thus we explore the possibly disruptive impact of applying peak-load-based tariffs on the budgets of households when they have been mainly charged for consumed volumes before. Our analysis estimates the change in household network expenditure for different combinations of energy, peak and fixed charges, and can help to design tariffs that recover the costs needed for the sustainable operation of the grid.

    This document reports an exploratory research project which aimed at developing a methodology of identification and prioritisation of actions to be implemented in Territorial Climate-Energy Plans (PCETs), while basing on rigorous technical-economic criteria. The Grenoble metropolitan area has been chosen as a case study because of the commitment of local authorities in a sustainable development approach, in particularly in the elaboration of a PCET. The method is notably based on the construction of a set of sector-related curves of Marginal Costs of Reduction of emissions (CMRs). Measures adopted by local authorities are identified for three specific sectors: transports, buildings, and energy production and distribution. The authors also took other actions into account, such as the modification of urban morphology as it has impacts on mobility and transport offer. The report describes the project context, methods used for the construction of sector-related CMR curves, structuring scenarios regarding evolutions of urban morphology, of population and jobs. It reports results obtained for the three studied sectors, and tries to draw lessons from this global approach in terms of strategy and methodology

    The attitude of local communities near a nuclear power plant (NPP) is a key factor in nuclear policy decision making in Japan. This case study compared local citizens' attitudes in 2010 and 2011 toward the benefits and drawbacks of hosting Kashiwazaki–Kariwa NPP. The Fukushima accident occurred in this period. After the accident, benefit recognition of utility bill refunds clearly declined, while that of public facilities did not, suggesting the influence of a bribery effect. The negative shift of attitudes about hosting the NPP after the accident was more modest in Kariwa Village, which saw a large expansion of social welfare programs, than in the other two areas, which lacked such a budget expansion. Policy implications of these results regarding the provision of economic incentives in NPP host areas after the Fukushima accident were discussed. - Highlights: • The Fukushima accident shocked Japan's nuclear policy. • Citizens' attitudes toward incentives of hosting a nuclear power plant surveyed. • More citizens thought negatively about incentives after the Fukushima accident. • The bribery effect, mode and amount of incentives affected citizens' attitudes

    In federal fiscal year 2000 (FY00), Berkeley Lab had 4,347 full- and part-time employees. In addition, at any given time of the year, there were more than 1,000 Laboratory guests. These guests, who also reside locally, have an important economic impact on the nine-county Bay Area. However, Berkeley Lab's total economic impact transcends the direct effects of payroll and purchasing. The direct dollars paid to the Lab's employees in the form of wages, salaries, and benefits, and payments made to contractors for goods and services, are respent by employees and contractors again and again in the local and greater economy. Further, while Berkeley Lab has a strong reputation for basic scientific research, many of the Lab's scientific discoveries and inventions have had direct application in industry, spawning new businesses and creating new opportunities for existing firms. This analysis updates the Economic Impact Analysis done in 1996, and its purpose is to describe the economic and geographic impact of Laboratory expenditures and to provide a qualitative understanding of how Berkeley Lab impacts and supports the local community. It is intended as a guide for state, local, and national policy makers as well as local community members. Unless otherwise noted, this analysis uses data from FY00, the most recent year for which full data are available.

  4. Relation between Observed and Perceived Traffic Noise and Socio-Economic Status in Urban Blocks of Different Characteristics

    Full Text Available Living in cities offers many benefits and thus more and more people are living in urban areas. However, the concentration of human activities also creates environmental stressors with severe influence on people’s health and well-being. Noise is an environmental stressor with known health impact. Despite this, studies investigating small-scale difference in noise exposure and annoyance are lacking. Against this background, this case study investigates environmental justice empirically, focusing on the distribution of road traffic noise and its perception in Hamburg, Germany. The study outlines a methodological approach that takes into account subjective and objective measures of exposure in small-scale residential blocks. The results show that annoyance by noise is clearly related to noise emission. Moreover, different groups are affected by noise pollution in our study area unequally. In particular, younger people and people with lower socio-economic status have higher probabilities to be affected by noise. Additionally, it emerged that participants reporting higher levels of annoyance from noise are on average younger than those feeling less annoyed. Overall, these results show that the current legal noise limits applicable to residential planning processes in German cities are not sufficient to prevent substantial annoyance effects in residential populations.

    1997-01-01

    'Maritsa East 2' TPP is one of the three power plants, situated in the area of the biggest coal field in Bulgaria. In the beginning of 1996 the thermal power plant had installed capacity 1450 MW. The effective and rational control of the production process is predetermined to a considerable extent by the level of the introduced automation. That is why since the end of 1989 an information and control microprocessor system MIK-2000 has been developed and next MIK-4000. The installed microprocessor systems have functional structure comprising the technological processes of the units and the whole plant. They include the operation stations of the units and the working places of the plant management, the production and technology department, the dispatch information unit and the main departments. The information and control microprocessor system (ICMS) performs operating, information and computing purposes. Use of automated systems by the plant personnel for information and control of technological, technical and economic parameters helps better operation control and enables formation of proper corrections in equipment operation mode

    This study uses spatiotemporal patterns in ambient concentrations to infer the contribution of regional versus local sources. We collected 12 months of monitoring data for outdoor fine particulate matter (PM 2.5 ) in rural southern India. Rural India includes more than one-tenth of the global population and annually accounts for around half a million air pollution deaths, yet little is known about the relative contribution of local sources to outdoor air pollution. We measured 1-min averaged outdoor PM 2.5 concentrations during June 2015-May 2016 in three villages, which varied in population size, socioeconomic status, and type and usage of domestic fuel. The daily geometric-mean PM 2.5 concentration was ∼30 μg m -3 (geometric standard deviation: ∼1.5). Concentrations exceeded the Indian National Ambient Air Quality standards (60 μg m -3 ) during 2-5% of observation days. Average concentrations were ∼25 μg m -3 higher during winter than during monsoon and ∼8 μg m -3 higher during morning hours than the diurnal average. A moving average subtraction method based on 1-min average PM 2.5 concentrations indicated that local contributions (e.g., nearby biomass combustion, brick kilns) were greater in the most populated village, and that overall the majority of ambient PM 2.5 in our study was regional, implying that local air pollution control strategies alone may have limited influence on local ambient concentrations. We compared the relatively new moving average subtraction method against a more established approach. Both methods broadly agree on the relative contribution of local sources across the three sites. The moving average subtraction method has broad applicability across locations. Copyright © 2018 The Authors. Published by Elsevier Ltd.. All rights reserved.

    2000-01-01

    In the ductile-brittle transition temperature region of SA508 C1.3 Mn-Mo-Ni low alloy steels, the relationship of the local fracture stress and carbides influencing the cleavage fracture behavior was investigated. Based on the ASTM E1921-97 standard method, the reference transition temperatures were determined by three point bending fracture toughness tests. A local fracture stress σ f * , was determined from a theoretical stress distribution in front of crack tip using the cleavage initiation distance measured in each fractured specimen surface. The local fracture stress values showed a strong relationship with toughness characteristics of the materials and those were larger in the materials of smaller carbide size. Quantitative analysis of carbides showed that carbides larger than a certain size are mainly responsible for the cleavage fracture in the ductile-brittle transition temperature region. (author)

  8. Investigation of local load effect on damping characteristics of synchronous generator using transfer-function block-diagram model

    2005-07-01

    Full Text Available The transfer-function block-diagram model of single-machine infinite-bus power system has been a popular analytical tool amongst power engineers for explaining and assessing synchronous generator dynamic behaviors. In previous studies, the effects of local load together with damper circuit on generator damping have not yet been addressed because neither of them was integrated into this model. Since the model only accounts for the generator main field circuit, it may not always yield a realistic damping assessment due to lack of damper circuit representation. This paper presents an extended transfer-function block-diagram model, which includes one of the q-axis damper circuits as well as local load. This allows a more realistic investigation of the local load effect on the generator damping. The extended model is applied to assess thegenerator dynamic performance. The results show that the damping power components mostly derived from the q-axis damper and the field circuits can be improved according to the local load. The frequency response method is employed to carry out the fundamental analysis.

    Hannon, Matthew J.; Bolton, Ronan

    2015-01-01

    This paper explores how some UK Local Authorities (LAs) have opted to engage with the Energy Service Company (ESCo) model in a bid to enhance their influence over local energy system change and help them to deliver on their political ‘public good’ objectives. Three common approaches to LA ESCo model engagement are outlined including the: (1) LA owned ‘arm's-length’ model; (2) private sector owned concession agreement model; and (3) community owned and run model. The LA's decision to establish its own ESCo, or alternatively enter into a partnership with another, predominantly depends on: its willingness to expose itself to risk, the level of strategic control it desires and the resources it has at its disposal. However, the business case is contingent on the extent to which the national policy and regulatory framework facilitates and obligates LAs to play an active energy governance role. Stronger alignment of local and national energy agendas through communication and coordination between different governance actors could help to remove critical barriers to LA ESCo engagement and their wider energy governance activities. - Highlights: • Some UK Local Authorities (LAs) have engaged with Energy Service Company (ESCo). • Driven by a desire to shape local energy system to deliver on their objectives. • LA may establish an ‘arm's length’ ESCo or partner with a private or community ESCo. • Trade-off between strategic control over energy system change and exposure to risk. • LA can bolster ESCo business case but ultimately depends on central government

    Individuals with certain personal, family and job characteristics are at elevated risk of poor mental health. Yet, the respective role of obesity, smoking, alcohol abuse, low education, income, living and family conditions, and socio-occupational category in fatigue/insomnia (FI), nervousness (N) and frequent drug use for those disorders (DFI and DN) among men and women and in gender disparities are not well known. We studied gender differences in FI, N, DFI, DN, and in their correlated, and whether the gender differences were mediated by individual and lifestyle factors among 3,450 active subjects aged 18-64, randomly selected from North-eastern France. Subjects completed a post-mailed questionnaire. Data were analyzed via adjusted odds ratio (ORa) computed with the logistic regression model. Women were more affected than men for FI (21.3 vs. 13.1%, OR adjusted for age ORa 1.80, 95% CI 1.50-2.16), DFI (11.6 vs. 7.1%, ORa 1.74, 1.38-2.21), N (14.7 vs. 9.9%, ORa 1.58, 1.28-1.94), and for DN (12.1 vs. 5.7%, ORa 2.29, 1.79-2.94). These differences were not mediated by the individual characteristics studied. Multivariate analysis showed that the risk patterns varied between the two sexes. Smoking was related to N in men as well as in women; alcohol abuse to DFI in men only; lack of family support to all outcome variables in men and women; low educational level to DFI in men only; low income to FI, N and DN in men and to FI and DN in women; being unmarried to DN in men; being divorced/separated to N and DN in women; being a manual worker to FI and being a farmer to DFI in men; and being a manual worker to DN and being an employee to FI in women (1.50 roles among men and women but they did not explain the gender disparities.

  12. Numerical simulations (2D) on the influence of pre-existing local structures and seismic source characteristics in earthquake-volcano interactions

    Farías, Cristian; Galván, Boris; Miller, Stephen A.

    2017-09-01

    Earthquake triggering of hydrothermal and volcanic systems is ubiquitous, but the underlying processes driving these systems are not well-understood. We numerically investigate the influence of seismic wave interaction with volcanic systems simulated as a trapped, high-pressure fluid reservoir connected to a fluid-filled fault system in a 2-D poroelastic medium. Different orientations and earthquake magnitudes are studied to quantify dynamic and static stress, and pore pressure changes induced by a seismic event. Results show that although the response of the system is mainly dominated by characteristics of the radiated seismic waves, local structures can also play an important role on the system dynamics. The fluid reservoir affects the seismic wave front, distorts the static overpressure pattern induced by the earthquake, and concentrates the kinetic energy of the incoming wave on its boundaries. The static volumetric stress pattern inside the fault system is also affected by the local structures. Our results show that local faults play an important role in earthquake-volcanic systems dynamics by concentrating kinetic energy inside and acting as wave-guides that have a breakwater-like behavior. This generates sudden changes in pore pressure, volumetric expansion, and stress gradients. Local structures also influence the regional Coulomb yield function. Our results show that local structures affect the dynamics of volcanic and hydrothermal systems, and should be taken into account when investigating triggering of these systems from nearby or distant earthquakes.

    The aim of this work was to estimate and describe the Medicare beneficiaries diagnosed with hepatitis C virus (HCV) in 2009, incremental annual costs by disease stage, incremental total Medicare HCV payments in 2009 using the Surveillance, Epidemiology, and End Results (SEER)-Medicare linked data covering the years 2002 to 2009. We weighted the 2009 SEER-Medicare data to create estimates of the number of patients with an HCV diagnosis, used an inverse probability-weighted two-part, probit, and generalized linear model to estimate incremental per patient per month costs, and used simulation to estimate annual 2009 Medicare burden, presented in 2014 dollars. We summarized patient characteristics, diagnoses, and costs from SEER-Medicare files into a person-year panel data set. We estimated there were 407,786 patients with diagnosed HCV in 2009, of whom 61.4% had one or more comorbidities defined by the study. In 2009, 68% of patients were diagnosed with chronic HCV only, 9% with cirrhosis, 12% with decompensated cirrhosis (DCC), 2% with liver cancer, 2% with a history of transplant, and 8% who died. Annual costs for patients with chronic infection only and DCC were higher than the values used in many previous cost-effectiveness studies, and treatment of DCC accounted for 63.9% of total Medicare's HCV expenditures. Medicare paid $2.7 billion (credible interval: $0.7-$4.6 billion) in incremental costs for HCV in 2009. The costs of HCV to Medicare in 2009 were substantial and expected to increase over the next decade. Annual costs for patients with chronic infection only and DCC were higher than values used in many cost-effectiveness analyses. © 2015 by the American Association for the Study of Liver Diseases.

    To investigate recorded and unrecorded alcohol and the relation to alcohol-related harm in a region with high taxation, economic deprivation and cultural use of alcohol. Two participants per household were systematically sampled from 12 different villages chosen using stratified random sampling in the North of Sabah, Malaysia. Participants were asked about each type and amount of drink consumed; price paid, whether tax was paid, number of days sick in the last year and whether they had experienced various health problems. A brief screen for mental disorders (PHQ) and an alcohol disorder screening test (AUDIT) were completed. Village heads were also interviewed about alcohol-related problems at village level. 470 people were interviewed. The most commonly drunk beverages were beer and Montoku (a local distilled beverage), which had average prices of RM3.85 and RM0.48 per standard drink respectively. Montoku was more likely to be drunk by problem drinkers. Only 3.1% of alcohol drunk was believed by respondents to be taxed. Men with an AUDIT score of more than 15 were more likely to have had a sick day in the last year and have a female household member with symptoms of mental disorder on PHQ. Change in the taxation structure needs to be considered to reduce alcohol-related harm. Most alcohol consumed in rural Sabah is smuggled or informal. The low price of local spirits is likely to be contributing to alcohol-related harm. Differential effects on minority populations need to be considered when designing alcohol policy. © The Author 2016. Medical Council on Alcohol and Oxford University Press. All rights reserved.

    Childhood circumstances such as socio-economic status and family structure have been found to influence psychological, psychosocial attributes and Oral Health Related Quality of Life (OHRQoL) in children. Therefore, the aim of this study was to conduct a systematic review of the published literature to assess the influence of parental Socio-Economic Status (SES) and home environment on children's OHRQoL. A systematic search was conducted in August 2013 using PubMed, Medline via OVID, CINAHL Plus via EBSCO, and Cochrane databases. Studies that have analysed the effect of parental characteristics (SES, family environment, family structure, number of siblings, household crowding, parents' age, and parents' oral health literacy) on children's OHRQoL were included. Quality assessment of the articles was done by the Effective Public Health Practice Project's Quality Assessment Tool for Quantitative studies. Database search retrieved a total of 2,849 titles after removing the duplicates, 36 articles were found to be relevant. Most of the studies were conducted on Brazilian children and were published in recent two years. Early Childhood Oral Health Impact Scale and Children's Perception Questionnaire were the instruments of choice in preschool and school aged children respectively. Findings from majority of the studies suggest that the children from families with high income, parental education and family economy had better OHRQoL. Mothers' age, family structure, household crowding and presence of siblings were significant predictors of children's OHRQoL. However, definitive conclusions from the studies reviewed are not possible due to the differences in the study population, parental characteristics considered, methods used and statistical tests performed.

    Recent studies have documented that a significant increase in the use of observation stays along with extensive variation in patterns of use across hospitals.The objective of this longitudinal observational study was to examine the extent to which patient, hospital, and local health system characteristics explain variation in observation stay rates across Veterans Health Administration (VHA) hospitals.Our data came from years 2005 to 2012 of the nationwide VHA Medical SAS inpatient and enrollment files, American Hospital Association Survey, and Area Health Resource File. We used these data to estimate linear regression models of hospitals' observation stay rates as a function of hospital, patient, and local health system characteristics, while controlling for time trends and Veterans Integrated Service Network level fixed effects.We found that observation stay rates are inversely related to hospital bed size and that hospitals with a greater proportion of younger or rural patients have higher observation stay rates. Observation stay rates were nearly 15 percentage points higher in 2012 than 2005.Although we identify several characteristics associated with variation in VHA hospital observation stay rates, many factors remain unmeasured.

    Twelve species of North American sea ducks (Tribe Mergini) winter off the eastern coast of the United States and Canada. Yet, despite their seasonal proximity to urbanized areas in this region, there is limited information on patterns of wintering sea duck habitat use. It is difficult to gather information on sea ducks because of the relative inaccessibility of their offshore locations, their high degree of mobility, and their aggregated distributions. To characterize environmental conditions that affect wintering distributions, as well as their geographic ranges, we analyzed count data on five species of sea ducks (black scoters Melanitta nigra americana, surf scoters M. perspicillata, white-winged scoters M. fusca, common eiders Somateria mollissima, and long-tailed ducks Clangula hyemalis) that were collected during the Atlantic Flyway Sea Duck Survey for ten years starting in the early 1990s. We modeled count data for each species within ten-nautical-mile linear survey segments using a zero-inflated negative binomial model that included four local-scale habitat covariates (sea surface temperature, mean bottom depth, maximum bottom slope, and a variable to indicate if the segment was in a bay or not), one broad-scale covariate (the North Atlantic Oscillation), and a temporal correlation component. Our results indicate that species distributions have strong latitudinal gradients and consistency in local habitat use. The North Atlantic Oscillation was the only environmental covariate that had a significant (but variable) effect on the expected count for all five species, suggesting that broad-scale climatic conditions may be directly or indirectly important to the distributions of wintering sea ducks. Our results provide critical information on species-habitat associations, elucidate the complicated relationship between the North Atlantic Oscillation, sea surface temperature, and local sea duck abundances, and should be useful in assessing the impacts of climate

    Following the occurrence of an extreme event, specific and immediate actions are oriented to relieve basic needs and guarantee the subsistence of daily life. One of the priorities is focused on the reconstruction and relocation to areas away from possible hazard. However, on a long-term perspective, new contexts, concerns and priorities among the affected as well as the immigrated population foster new risk perceptions, which in many cases may include the returning or settlement in areas exposed to hazards. In Santa Teresa (Cusco, Peru), risk has been part of its history. In 1998, two very large debris flows from deglaciated areas, in January and February respectively, destroyed the old city located by the riverside of the Sacsara river; including the loss of lives, housing, loss of infrastructure and roads, electricity and water cuts, among other important losses. Today, the new city is located on a terrace above the river reach; and their current inhabitants, mainly migrants from different cities of the region of Cusco, have a different perspective of this experience. On the contrary, many of the inhabitants who experienced these events have returned to the risk areas where they lost everything, or they have settled in disaster prone areas. There is a set of factors, such as local knowledge (regarding space, economy, etc.) and new social contexts (such as the rise of tourism in risk areas, for example) that are implicit in the current narratives regarding hazard and risk. This work purposes the following questions: how does the social and economic context, as well as local knowledge influence risk perceptions? Are there any differences concerning risk perceptions between groups who decided to live in disaster prone areas and groups who are less exposed to risk? And which are the strategies within the groups regarding risk, considering how this concept is understood among them? In order to analyze these questions, this work is based on a case study in the

    In wall-stabilized arc which is a very useful means for determining the transport characteristics of high temperature gases, it is the premise that the inside of arc column is in complete local thermal equilibrium (LTE). In general, the higher the gas pressure, the easier the establishment of LTE, accordingly the experimental investigations on the characteristics of arc discharge as well as the transport characteristics so far were limited to the region of relatively high pressure. However, the authors have found that the theoretical potential vs. current characteristic obtained by the transport characteristic was greatly different from the actually measured one in low pressure region, as the fundamental characteristic of wall-stabilized argon plasma arc below atmospheric pressure. This time, they have clarified this discrepancy at 0.1 atm using the plasma parameters obtained through the spectroscopic measurements. The spectroscopic measurements have been performed through the side observation window at the position 5.5 cm away from the cathode, when arc was ignited vertically at the electrodes distant by 11 cm. Arc radius was 0.5 cm. Electron density and temperature, gas temperature and the excitation density of argon neutral atoms have been experimentally measured. The investigations showed that, in the region of low arc current, where the ratio of current to arc radius is less than 200 A/cm, the fall of gas temperature affected greatly on the decrease of axial electric field of arc column. The non-equilibrium between electron temperature and gas temperature decreased with the increase of arc current, and it was concluded that LTE has been formed at the center portion of arc column above I/R = 300 A/cm.

  2. Use of microwave remote sensing data to monitor spatio temporal characteristics of surface soil moisture at local and regional scales

    Full Text Available Hydrologic processes, such as runoff production or evapotranspiration, largely depend on the variation of soil moisture and its spatial pattern. The interaction of electromagnetic waves with the land surface can be dependant on the water content of the uppermost soil layer. Especially in the microwave domain of the electromagnetic spectrum, this is the case. New sensors as e.g. ENVISAT ASAR, allow for frequent, synoptically and homogeneous image acquisitions over larger areas. Parameter inversion models are therefore developed to derive bio- and geophysical parameters from the image products. The paper presents a soil moisture inversion model for ENVISAT ASAR data for local and regional scale applications. The model is validated against in situ soil moisture measurements. The various sources of uncertainties, being related to the inversion process are assessed and quantified.

    Electron beam welding of UNS S41500, a low carbon martensitic stainless steel utilized in hydroelectric turbine manufacturing, was investigated by applying a single pass autogenous process to penetrate a section thickness of 72 mm without preheating. In the as-welded and post-weld heat treated conditions, the evolution in microhardness and microstructure across the weldments, as well as the global and local tensile properties, were evaluated. In the as-welded condition, assessment of the microhardness and the associated microstructure across the welds led to the identification of six regions, including the fusion zone, four heat affected zones and the base metal; each of these regions consisted of different phase constituents, such as tempered martensite, untempered martensite, delta ferrite and retained austenite. Post-weld heat treatment, undertaken to temper the untempered martensite in the as-welded microstructure, was effective in homogenizing the hardness across the weldment. The mechanical response of the welds, determined through tensile testing at room temperature with an automated non-contact three-dimensional deformation measurement system, indicated that the global tensile properties in the as-welded and post-weld heat treated conditions met the acceptance criteria in the ASME Section IX standard. Also, evaluation of the local tensile properties in the fusion and heat affected zones of the as-welded samples allowed a more comprehensive understanding of the strength and ductility associated with the different microstructures in the “composite” nature of the weldment. Fractographic analysis demonstrated dimpled features on the tensile fracture surfaces and failure was associated with debonding between the martensitic matrix and the secondary phases (such as delta ferrite and retained austenite) that resulted in the formation, growth and coalescence of voids into a macroscale crack.

    This study explores the economic consequences of earthquakes. In particular, it is investigated how exposure to earthquakes affects economic growth both across and within countries. The key result of the empirical analysis is that while there are no observable effects at the country level, earthquake exposure significantly decreases 5-year economic growth at the local level. Areas at lower stages of economic development suffer harder in terms of economic growth than richer areas. In addition,...

    The current polemic about the possibilities of sustainable development has led to a renovated interest for the topic of the sustainability of the communities and the local sustainability. In front of the global sustainability whose conditions have been exposed by systemic ecologists and for macro economists, the sustainability of specific places arises in the planet whose conditions are object of study of the ecology of landscapes, of the ecological economy, of the cultural anthropology, of the environmental sociology and naturally, of the integral environmentalism. In this discussion the Colombian case charges unusual interest to be one of the few countries of Latin America, where a very dense net of municipalities exists, each one with its urban helmet and with a position and some functions defined by the political constitution of the nation. This net of municipalities and of urban helmets it also constitutes net of alternative to the current macro-cephalic situation. As well as Bogota grew, in a hundred years, of less than a hundred thousand inhabitants to six million inhabitants, each one of these municipalities contains a potential of growth that depends on the characteristics of its ecological, social, economic and politic sustainability

  6. Local influence of south-east France topography and land cover on the distribution and characteristics of intense rainfall cells

    The Greater Lyon area is strongly built up, grouping 58 communes and a population of 1.3 million in approximately 500 km2. The flood risk is high as the territory is crossed by two large watercourses and by streams with torrential flow. Floods may also occur in case of runoff after heavy rain or because of a rise in the groundwater level. The whole territory can therefore be affected, and it is necessary to possess in-depth knowledge of the depths, causes and consequences of rainfall to achieve better management of precipitation in urban areas and to reduce flood risk. This study is thus focused on the effects of topography and land cover on the occurrence, intensity and area of intense rainfall cells. They are identified by local radar meteorology (C-band) combined with a processing algorithm running in a geographic information system (GIS) which identified 109,979 weighted mean centres of them in a sample composed of the five most intense rainfall events from 2001 to 2005. First, analysis of spatial distribution at an overall scale is performed, completed by study at a more detailed scale. The results show that the distribution of high-intensity rainfall cells is spread in cluster form. Subsequently, comparison of intense rainfall cells with the topography shows that cell density is closely linked with land slope but that, above all, urbanised zones feature nearly twice as many rainfall cells as farm land or forest, with more intense intensity.

    Using autoradiography combined with immunocytochemistry, the authors demonstrated that the target cells of CRH in the human pituitary were proopiomelanocortin cells. Scatchard analysis of (125I)Tyr0-oCRH saturation binding revealed the presence of one class of saturable, high affinity sites on pituitary tissue homogenate. The equilibrium dissociation constant (Kd) for (125I)Tyr0-oCRH ranged from 1.1-1.6 nM, and the receptor density was between 200-350 fmol/mg protein. Fixation of cryostat sections with 4% paraformaldehyde before tracer incubation improved both tissue preservation and localization of the CRH receptor at the cellular level. Additional postfixation with 1% glutaraldehyde inhibited tracer diffusion during subsequent immunocytochemistry and autoradiography. (125I)Tyr0-oCRH was found in cytoplasmic inclusions or at the cell periphery of ACTH/beta-endorphin cells in the anterior pituitary. Single cells of the posterior pituitary were also CRH receptor positive. Cells staining for PRL or GH were CRH receptor negative. They conclude that CRH binds only to high affinity receptors on ACTH/{beta}-endorphin cells in the human pituitary.

    Temporal lobe injury (TLI) is a debilitating complication after radiotherapy for nasopharyngeal carcinoma (NPC), especially in patients who suffer treatment relapses and receive re-irradiation. We explored the clinical characteristics and prognostic factors of TLI in locally recurrent NPC (rNPC) patients after re-irradiation using intensity modulated radiotherapy (IMRT). A total of 454 temporal lobes (TLs) from 227 locally rNPC patients were reviewed. The clinical characteristics of TLI were analyzed. In the two radiotherapy courses, the equivalent dose in 2 Gy per fraction (EQD2) for the TLs was recalculated to facilitate comparison of the individual data. The median follow-up time was 31 (range, 3-127) months. After re-irradiation using IMRT, 31.3 % (71/227) of patients developed TLI. The median latency of TLI was 15 (range, 4-100) months. Univariate and multivariate analysis showed that the interval time (IT) between the two courses of radiotherapy and the summation of the maximum doses of the two radiotherapy courses (EQD2 - ∑max) were independent factors influencing TLI. The 5-year incidence of TLI for an IT ≤26 or >26 months was 35.9 and 53.7 % respectively (p = 0.024). The median maximum doses delivered to the injured TLs were significantly higher than was the case for the uninjured TLs after two courses of radiotherapy (135.3 and 129.8 Gy, respectively: p 2-year interval was found to be relatively safe.

  9. Inverter sizing of grid-connected photovoltaic systems in the light of local solar resource distribution characteristics and temperature

    Inverter sizing strategies for grid-connected photovoltaic (PV) systems often do not take into account site-dependent peculiarities of ambient temperature, inverter operating temperature and solar irradiation distribution characteristics. The operating temperature affects PV modules and inverters in different ways and PV systems will hardly ever have a DC output equal to or above their STC-rated nominal power. Inverters are usually sized with a nominal AC output power some 30% (sometimes even more) below the PV array nominal power. In this paper, we show that this practice might lead to considerable energy losses, especially in the case of PV technologies with high temperature coefficients of power operating at sites with cold climates and of PV technologies with low temperature coefficients of power operating at sites with warm climates and an energy distribution of sunlight shifted to higher irradiation levels. In energy markets where PV kWh are paid premium tariffs, like in Germany, energy yield optimization might result in a favorable payback of the extra capital invested in a larger inverter. This paper discusses how the time resolution of solar radiation data influences the correct sizing of PV plants. We demonstrate that using instant (10s) irradiation values instead of average hourly irradiation values leads to considerable differences in optimum inverter sizing. When calculating inverter yearly efficiency values using both, hourly averages and 1-min averages, we can show that with increased time resolution of solar irradiation data there are higher calculated losses due to inverter undersizing. This reveals that hourly averages hide important irradiation peaks that need to be considered. We performed these calculations for data sets from pyranometer readings from Freiburg (48{sup o}N, Germany) and Florianopolis (27{sup o}S, Brazil) to further show the peculiarities of the site-dependent distribution of irradiation levels and its effects on inverter sizing

    The pylorus, an important part of the digestive tract controlling the flow of chyme between the stomach and the duodenum, is widely innervated by intrinsic and extrinsic nerves. To determine the locations of postganglionic sympathetic perikarya that innervate the pylorus of the domestic pig, a retrograde tracing method with application of Fast Blue tracer was used. All positive neuronal cell bodies (ca. 1750) were found in the celiac-cranial mesenteric ganglion complex (CSMG), however, the coeliac poles of this complex provided the major input to the pylorus. Afterwards, the immunohistochemical staining procedure was applied to determine biologically active substances expressed in the FB-labeled perikarya. Approximately 77% of the FB-positive cell bodies contained tyrosine hydroxylase (TH), 87% dopamine β-hydroxylase (DβH), 40% neuropeptide Y (NPY), 12% somatostatin (SOM) and 7% galanin (GAL). The presence of all these substances in the ganglion tissue was confirmed by RT-PCR technique. Double immunocytochemistry revealed that all of the TH-positive perikarya contained DβH, about 40% NPY, 12% SOM and 8% GAL. Additionally, all above-cited immunohistochemical markers as well as VIP, PACAP, ChAT, LEU, MET, SP and nNOS were observed within nerve fibers associated with the FB-positive perikarya. Immunocytochemical labeling of the pyloric wall tissue disclosed that TH+, DβH+ and NPY+ nerve fibers innervated ganglia of the myenteric and submucosal plexuses, blood vessels, both muscular layers and the muscularis mucosae; nerve fibers immunoreactive to GAL mostly innervated both muscular layers, while SOM+ nerve fibers were observed within the myenteric plexus. Presented study revealed sources of origin and immunohistochemical characteristics of the sympathetic postganglionic perikarya innervating the porcine pylorus. Copyright © 2011 Elsevier B.V.

    The purpose of this study was to investigate the association of selected characteristics of local health departments (LHDs) in Kentucky with the receipt of information by external stakeholders, specifically physicians and pharmacists, during the initial H1N1 outbreak of 2009. This study utilized a cross-sectional survey to gather characteristic information from local health departments. In addition, cross sectional surveys of physicians and pharmacists were used to determine information receipt. All 54 LHDs in Kentucky were surveyed; however, only those physicians belonging to the Kentucky Family Physician Association or the Kentucky Ambulatory Network were surveyed. Also, pharmacists included in this survey were members of the Kentucky Pharmacist Association. Descriptive data analyses, including chi-square test of independence, were conducted, and generalized estimating equations were used to calculate odds ratios to depict associations related to information exchange in this study. Response rates for the study were as follows: LHDs 65% (35/54), physicians 18.5% (96/518), and pharmacists 21.1% (211/1000). Of the 35 participating LHDs the most common characteristic identified was the presence of a public information officer (PIO) and a pandemic influenza plan, 76% and 64%, respectively. Despite these factors, 72% of external stakeholders did not receive any information regarding H1N1 from the LHD. Generalized estimating equations also indicated that stakeholders in jurisdictions lacking a PIO had 6 (95% confidence interval, 1.3-26.95) greater odds of not receiving information from the LHD. External stakeholders in jurisdictions without a pandemic influenza plan had 3.38 (95% confidence interval, 0.80-1.17) increased odds of not receiving information but this association was not statistically significant. Observations from this study indicate a need to improve information exchange between LHDs and their external stakeholders, specifically physicians and pharmacists

    Since 2013, local authorities in England have been responsible for commissioning preventative public health interventions. The aim of this systematic review was to support commissioning by collating published data on economic evaluations and modelling of local authority commissioned public health preventative interventions in the UK. Following the PRISMA protocol, we searched for economic evaluations of preventative intervention studies in four different areas: overweight and obesity, physical inactivity, alcohol and illicit drugs use and smoking cessation. The systematic review identified studies between January 1994 and February 2015, using five databases. We synthesized the studies to identify the key methods and examined results of the economic evaluations. The majority of the evaluations related to cost-effectiveness, rather than cost-benefit analyses or cost-utility analyses. These analyses found preventative interventions to be cost effective, though the context of the interventions differed between the studies. Preventative public health interventions in general are cost-effective. There is a need for further studies to support justification of continued and/or increased funding for public health interventions. There is much variation between the types of economically evaluated preventative interventions in our review. Broader studies incorporating different contexts may help support funding for local authority-sponsored public health initiatives.

    We studied dampness and mold in homes in relation to climate, building characteristics and socio-economic status (SES) across Europe, for 7127 homes in 22 centers. A subsample of 3118 homes was inspected. Multilevel analysis was applied, including age, gender, center, SES, climate, and building factors. Self-reported water damage (10%), damp spots (21%), and mold (16%) in past year were similar as observed data (19% dampness and 14% mold). Ambient temperature was associated with self-reported water damage (OR=1.63 per 10°C; 95% CI 1.02-2.63), damp spots (OR=2.95; 95% CI 1.98-4.39), and mold (OR=2.28; 95% CI 1.04-4.67). Precipitation was associated with water damage (OR=1.12 per 100 mm; 95% CI 1.02-1.23) and damp spots (OR=1.11; 95% CI 1.02-1.20). Ambient relative air humidity was not associated with indoor dampness and mold.

    This study's objective was to describe characteristics, treatment patterns, and economic outcomes of type 2 diabetes mellitus (T2DM) patients initiating injectable antidiabetic medications in Japan. Adults (≥ 18 years) with T2DM, ≥ 2 claims for injectable antidiabetics between 1 August 2011 and 31 July 2015 (first claim = index date), no evidence of type 1 diabetes mellitus, ≤ 1 claim for insulin, no claims for GLP-1RA before index, and continuous enrollment for 6 months before (baseline) and 12 months after index (follow-up) were selected from the Japan Medical Center Database. Patient characteristics and outcomes during the baseline and follow-up periods were described overall and by provider, using the proxy setting of index medication [hospital (including outpatient departments) for specialists; clinic for general practitioner (GP)]. Of the 2683 patients included (mean age: 50 years, 67% male), 1879 (70%) initiated injectable antidiabetics with specialists and 804 (30%) with GPs. The specialist cohort had a significantly greater comorbidity burden, but lower HbA1c levels during baseline, and was more likely to receive intensified treatment at index than the GP cohort. Almost 40% of patients (almost 30% of GP cohort) did not use antidiabetics during baseline; the remaining patients received oral medications, primarily from GPs. During follow-up, patients used the index medication for approximately 7 months. Independent of specialist vs. GP setting, patients received antidiabetics and medications for T2DM-related comorbidities and complications during the baseline and follow-up periods from the same provider, primarily GPs. The overall average healthcare costs were ¥350,404 during baseline and ¥1,856,727 during follow-up. In Japan, most T2DM patients initiated injectable antidiabetics with specialists vs. GPs. There were considerable differences in characteristics of patients treated by specialists vs. GPs. After initiation, injectable

    Few studies of ethnicity and prostate cancer have included Latino men in analyses of baseline clinical characteristics, treatment selection, and disease-free survival (DFS). The present study examines the impact of Latino ethnicity on these parameters in a large, multiinstitutional database of men with prostate cancer. We compared baseline disease characteristics and clinical outcomes for Latino (N = 138), non-Latino White (NLW, N = 5619), and African-American (AA, N = 608) men with localized prostate cancer by using chi-square and ANOVA for baseline variables and survival analysis to examine differences in time to recurrence. Latino men resembled AA men more than NLW on sociodemographic characteristics. AA men had higher Gleason scores and prostate-specific antigen (PSA) at diagnosis than Latino or NLW men (both P Latino and AA men presented with advanced disease (T3b/T4/N+/M+) versus 4% of NLW (P Latino men did not receive different treatments than NLW or AA men after controlling for clinical and demographic factors; however, AA men were more likely to receive external beam radiation (OR = 1.51, 95% confidence interval [CI] = 0.99-2.31) and hormone treatment (OR = 1.56, 95% CI = 1.05-2.32) then NLW men. For prostatectomy patients, 3-year actuarial DFS rates were 83% for NLW men and 86% for Latino men versus 69% for AA men (P Latinos are more similar to African Americans on sociodemographic characteristics but more similar to NLW on clinical presentation, treatments received, and DFS.

  19. What's so local about global climate change? Testing social theories of environmental degradation to quantify the demographic, economic, and governmental factors associated with energy consumption and carbon dioxide emissions in U.S. metropolitan areas and counties

    Tribbia, John Luke

    . The STIRPAT method is used to test four social theories of environmental degradation -- the treadmill of production, ecological modernization, urban ecological transitions, and human ecology theories -- by quantifying variables associated with energy use and CO2 emissions drawn from each theory. The specific findings demonstrate that various demographic, economic, and governmental factors are related strongly to metropolitan area energy consumption and county-level CO2 emissions. The human ecology, treadmill of production, and urban ecological transitions theories are important to explaining how and why climate-related impacts differ for a wide variety of local areas in the United States. Related to human ecology and treadmill of production theory, environmental degradation is highest in metropolitan areas and counties with large populations and large economies that have various mechanisms in place to facilitate economic growth. By contrast, some U.S. counties are beginning to remedy their impact on the environment by applying economic and governmental resources toward the mitigation of CO2 emissions, which provides evidence of support for urban ecological transitions theory. However, because climate change is a complex cross-scale global environmental problem and the results in this dissertation confirm that this problem is locally driven by similar population and economic factors also affecting the climate at larger spatial scales, mitigation efforts to reduce energy use and emissions at the local level will be fruitless without a well-coordinated, cross-scale (local to global) ideological shift that puts less priority on economic goals and more on environmental sustainability. These results, and the methodological and theoretical framework applied in this dissertation, thus provide a useful platform for the successful application of future research that specifically addresses mitigation strategies to reduce local-level environmental impacts.

    In the biomedical field, the laser Doppler flowmetry (LDF) technique is a non-invasive method to monitor skin perfusion. On the skin of healthy humans, LDF signals present a significant transient increase in response to a local and progressive pressure application. This vasodilatory reflex response may have important implications for cutaneous pathologies involved in various neurological diseases and in the pathophysiology of decubitus ulcers. The present work analyses the dynamic characteristics of these signals on young type 1 diabetic patients, and on healthy age-matched subjects. To obtain accurate dynamic characteristic values, a de-noising wavelet-based algorithm is first applied to LDF signals. All the de-noised signals are then normalised to the same value. The blood flow peak and the time to reach this peak are then calculated on each computed signal. The results show that a large vasodilation is present on signals of healthy subjects. The mean peak occurs at a pressure of 3.2 kPa approximately. However, a vasodilation of limited amplitude appears on type 1 diabetic patients. The maximum value is visualised, on the average, when the pressure is 1.1 kPa. The inability for diabetic patients to increase largely their cutaneous blood flow may bring explanations to foot ulcers.

    Access to potable water is grossly inadequate in Douala-Cameroon. The situation is worse in slum areas, compelling inhabitants to obtain water from sources of doubtful quality. This has contributed to frequent outbreaks of water-borne diseases particularly cholera, which results in severe morbidity and mortality. Shallow wells are a major source of water in these areas. We analyzed the influence of some factors on the bacteriological quality of well water in Bepanda and New Bell, cholera endemic localities in Douala to generate data that would serve as basis for strengthening of water and health policies. Questionnaires were administered to inhabitants of study sites to appraise their hygiene and sanitation practices, and level of awareness of waterborne diseases. The bacteriological quality of water was determined by investigating bacterial indicators of water quality. Relationship between well characteristics and bacteriological quality of water was determined using χ² test. The Kendall tau_b nonparametric correlation was used to measure the strength of association between well characteristics and bacteriological parameters. Statistics were discussed at 95% confidence level. Antibiotic susceptibility of isolates was investigated by the Kirby-Bauer and broth dilution techniques. Multidrug resistant species were tested for extended β-lactamase production potential. Inhabitants demonstrated adequate knowledge of waterborne diseases but employed inappropriate method (table salt) for well disinfection. Well construction and location violated guidelines. Indicator bacterial counts greatly exceeded the WHO guidelines. Variation in bacteriologic parameters between sites was not significant (P > 0.05) since well characteristics and hygiene and sanitary practices were similar. Differences in bacteriologic quality with respect to state of well, and presence of molded casing and lid, and height of casing were not significant (P > 0.05). Well distance from sanitary

    Recent scholarship has frequently emphasized modern states' use of social science to impose universalized conceptions of rationality and order upon diverse, highly localized settings. The New Deal era experiences of William M. Leiserson and David J. Saposs, however, provide an analytical alternative. As students of the pioneering labor economist John R. Commons, Leiserson and Saposs sought to create mechanisms for state oversight of industrial labor relations that recognized local practices and arrangements. Although their approach failed to take hold within the National Labor Relations Board, localized institutional and political contingencies, and not a hegemonic modernism, account best for their frustrated aspirations in the late 1930s. © 2010 Wiley Periodicals, Inc.

    Highlights: • The source of the membrane constraint due to local temperature fluctuation was shown. • Thermal fatigue that occurred at a mixing tee and branched elbow was analyzed. • Cracking occurrence was reasonably explained by the constraint and stress conditions. - Abstract: This study was aimed at identifying the constraint conditions under local temperature fluctuation by thermal striping at a mixing tee and by thermal stratification at an elbow pipe branched from the main pipe. Numerical and analytical approaches were made to derive the thermal stress and its fluctuation. It was shown that an inhomogeneous temperature distribution in a straight pipe caused thermal stress due to a membrane constraint even if an external membrane constraint did not act on the pipe. Although the membrane constraint increased the mean stress at the mixing tee, it did not contribute to fluctuation of the thermal stress. On the other hand, the membrane constraint played an important role in the fatigue damage accumulation near the stratification layer of the branched elbow. Based on the constraint and stress conditions analyzed, the characteristics of the cracking observed in actual nuclear power plants were reasonably explained. Namely, at the mixing tee, where thermal crazing has been found, the lack of contribution of the membrane constraint to stress fluctuation caused a stress gradient in the thickness direction and arrested crack growth. On the other hand, at the branched elbow, where axial through-wall cracks have been found, the relatively large hoop stress fluctuation was brought about by movement of the stratified layer together with the membrane constraint even under a relatively low frequency of stress fluctuation

    Large reservoirs play a key role in regional hydrological cycles as well as in modulating the local climate. The emerging large reservoirs in concomitant with rapid hydropower exploitation in southwestern China warrant better understanding of their impacts on local and regional climates. One of the crucial pathways through which reservoirs impact the climate is lake-atmospheric interaction. Although such interactions have been widely studied with numeric weather prediction (NWP) models, an outstanding limitation across various NWPs resides on the poor thermodynamic representation of lakes. The recent version of Weather Research and Forecasting (WRF) system has been equipped with a one-dimensional lake model to better represent the thermodynamics of large water body and has been shown to enhance the its predication skill in the lake-atmospheric interaction. In this study, we further explore the applicability of the WRF-Lake system in two reservoirs with contrasting characteristics: Miyun Reservoir with an average depth of 30 meters in North China Plain, and Nuozhadu Reservoir with an average depth of 200 meters in the Tibetan Plateau Region. Driven by the high spatiotemporal resolution meteorological forcing data, the WRF-Lake system is used to simulate the water temperature and surface energy budgets of the two reservoirs after the evaluation against temperature observations. The simulated results show the WRF-Lake model can well predict the vertical profile of water temperature in Miyun Reservoir, but underestimates deep water temperature and overestimates surface temperature in the deeper Nuozhadu Reservoir. In addition, sensitivity analysis indicates the poor performance of the WRF-Lake system in Nuozhadu Reservoir could be attributed to the weak vertical mixing in the model, which can be improved by tuning the eddy diffusion coefficient ke .

    Objectives We examined the association between structural social capital and public health services use, and explored the modifiable effect of neighbourhood factors on this association among domestic migrants in China. Methods Data were from a 2014 nationally representative cross-sectional sample of domestic migrants aged 15–59 years in China. Survey-weighted logistic regression models were applied to assess the association between structural social capital, measured by participation in social organisations and social activities, and use of public health services. Interaction terms between neighbourhood urban status, neighbourhood composition and social capital were further assessed in the models. Results Migrants who participated in social organisations were more likely to establish health records (OR 1.467, 95% CI 1.201 to 1.793) and receive health education information (OR 1.729, 95% CI 1.484 to 2.016) than those who did not. Participation in social activities was positively associated with establishing health records only in urban communities (OR 1.853, 95% CI 1.060 to 3.239), and it was positively linked to receiving health education information among those living with a higher percentage of local neighbours (OR 1.451, 95% CI 1.044 to 2.017). Conclusions Structural social capital was related to an increased utilisation of local public health services among migrants. The findings of this study provided new evidence for the differential influences of social capital by neighbourhood characteristics in China, which suggested the importance to enhance social capital in rural/suburban communities and communities where the majority of the residents were migrants.

    To evaluate the efficacy of topical administration of a 2% solution of cyclosporine (CsA) for treatment of dogs with keratoconjunctivitis sicca (KCS) and to correlate results with histopathologic characteristics and local cellular immunity of the gland of the third eyelid. 24 dogs with bilateral KCS. Lacrimal secretion was measured, using Schirmer tear test (STT) strips. Leukocyte and T-lymphocyte subsets were determined in blood samples. Histopathologic changes as well as CD4+, CD8+, and alpha-naphthyl-acetate esterase-positive (ANAE+) lymphocytes were evaluated. Clinical signs resolved at the end of 1 month in conjunction with significantly increased STT values, compared with baseline values. Fifteen and 30 days after discontinuation of CsA treatment, a decrease was observed in STT values in both eyes; however, only values for the right eye were significantly different. There was a significant decrease in the number of lymphocytes and ANAE+ lymphocytes 15 and 30 days after discontinuation of CsA treatment, compared with baseline values. Differences were not observed in number of CD4+ lymphocytes among treatment groups. However, there was a significant decrease in number of CD8+ lymphocytes with reversal of the CD4+:CD8+ in both eyes after CsA treatment for 30 days, compared with the control group. Increased secretory activity and decreased lymphocyte infiltration were characteristic histopathologic findings. Topical administration of a 2% solution of CsA was effective for the treatment of dogs with KCS. Strict follow-up monitoring is required after the cessation of treatment because of the possibility of recurrence of KCS.

    Full Text Available The paper analyzes the capitalism characteristics in the Portuguese social formation, considering economic groups in Portugal before and after of April 25. Detailing the characteristics of these economic groups, the author concludes that the principal shareholders of most economic and financial groups operating in Portugal, are transnational groups, some companies belonging to foreign States and other large economic and financial groups operating on a global scale. Accordingly, the State role, given the fragility towards these groups, is of simple server and executor of policies dictated by these groups directly or, indirectly by international organizations that represent and defend their interests, like the IMF, the Commission European, the World Bank, even the OECD, etc. Argues that given the growing globalization and increased threats of all kinds, one needs in Portugal is a strong State that defend the national sovereignty, able of promote the growth and sustained development of the country, and to defend the Portuguese of threats and constant attacks to a life with a minimum of human dignity.

This aims to evaluate different adaptation measures concerning the eradication and containment strategies economically. The focus of the analysis is mainly the crop rotation and the reduction of the proportion of maize at farm level. InVeKoS-data are analyzed, in order to assess the economic relevance of the pest in Bavaria in a better way. These enable detailed information on the development of maize production and cropping intensity. Subsequently research regions are defined with a high maize density, expecting enhanced damage from the beetle. In these selected areas single farms are selected. For considerations on single farm level, farms with different farm types are chosen by which adaptation measures are evaluated and realistic impact assessment could be made. For the evaluation of the economic impacts a whole-farm simulation has been used to include indirect effects of different adoption strategies. Additional, semi-structured interviews were conducted at selected farms in order to prove the results of the case study, obtain more information about the consequences on farm level and to evaluate the proposed cultivation alternatives for maize. A benefit-cost analysis and the comparative analysis of possible damage caused by the beetle and cost adjustments complete the study.

    Full Text Available As a new concept in the literature, the authors discuss the conception of “Economic Creativ-ity” (EC. The authors explain psychological characteristics of “Economic Creativity”: atti-tudes, motivation, personality traits, and abili-ties. They propose a design based on Emotion of Thought Theory (Kazemi, 2007 for Economic Creativity Development (ECD. This theory is an affective-cognitive approach that tries to ex-plain creativity. Emotion of Thought involves “Poyaei” and “Bitabi” (in Persian meaning Dy-namism and Restlessness. According to this theory, ECD relates to connections between emotion and thought. The ECD includes pro-moting individual readiness, utilization of eco-nomic resources, attitude towards economic af-fairs development, enhancing the utilization of economic experiences, conducting economic ac-tivity education, development of economic thinking and development of emotion of thought.

    The development of high-level nuclear waste repositories can be expected to produce a substantial stimulus to the local economy, but the magnitude and speed of this stimulus may pose planning problems for nearby communities. The chapter is divided into two major sections: 1) a review of the major economic and fiscal effects likely to occur, and 2) a discussion of the methods and techniques which can be used to estimate the magnitude, timing, and distribution of such effects. The six categories of effects described are those on employment patterns and characteristics, income, local trade and service firms, community price structure changes, other basic economic sectors, and public sector costs and revenues

    Full Text Available A locals collection is a set of parameters that are used to delimit data-mining operations. This piece uses a collection of locals from around Essex Massachusetts to shape and delimit an interrogation of post-reality in contemporary America. It explores the notion of crisis, the possibility of a crisis of empire that may or may not emerge in a media-space that does not allow crisis of empire to be mentioned and relations this maybe-crisis to the various levels of economic dysfunction that have become evident since late 2008. But mostly this piece explores ways in which particular stories about particular people do and do not link/link to these larger-scale narratives. This is the first of a potential series of locals collections that will mine the American post-real.

    Biodegradable magnesium-calcium (MgCa) alloy is a very attractive biomaterial. Two MgCa alloys below the solid solubility of Ca were considered, as to solely investigate the effect of Ca content on the behavior of magnesium and the pH changes associated to metal dissolution. X-ray diffraction analysis and optical microscopy showed that both Mg-0.63Ca and Mg-0.89Ca alloys were solely composed of α(Mg) phase. Degradation characteristics and electrochemical characterization of MgCa alloys were investigated during exposure to Ringer's solution at 37 °C by electrochemical impedance spectroscopy and scanning electrochemical microscopy. The impedance behavior showed both capacitive and inductive features that are related to the alloy charge transfer reaction and the relaxation of the absorbed corrosion compounds, and can be described in terms of an equivalent circuit. Scanning electron microscopy (SEM) was employed to view the surface morphology of the MgCa samples after 1 week immersion in Ringer's solution showing extensive precipitation of corrosion products, whereas the substrate shows evidence of a non-uniform corrosion process. Energy dispersive analysis showed that the precipitates contained oxygen, calcium, magnesium and chlorine, and the Mg:Ca ratios were smaller than in the alloys. Scanning electrochemical microscopy (SECM) was used to visualize local pH changes associated to these physicochemical processes with high spatial resolution. The occurrence of pH variations in excess of 3 units between anodic and cathodic half-cell reactions was monitored in situ. Copyright © 2015 Elsevier B.V. All rights reserved.

    Full Text Available Aim of the article is to study and generalize scientific approaches to the determination of essence, content and components of financial resources of local authorities. The methodology is the use of various general scientific and special methods of research. So, during the study the following methods were used: dialectic method, with the help of which the essence of financial resources of local authorities was determined; methods of comparative analysis of scientific thoughts about the category “financial resources”, “financial resources of local authorities”; systematization of main characteristics of financial resources at the level of state and local authorities; structuralfunctional method in order to classify financial resources. Study results are represented by determination of economic essence of financial resources, their main features, and it is proposed an improvement of the concept “financial resources”, “financial resources of local authorities”. Financial resources are an aggregate of resources (monetary and non-monetary, which are creating and forming owning to distribution and redistribution of gross domestic product by economic entities, households, state and local authorities and are in fund and non-fund form with the aim to ensure their purposeful productive use for the benefit of natural and legal persons as well as society in general. Thus, the financial resources of local authorities – are an aggregate of monetary resources created as a result of the distribution and redistribution of the gross domestic product (some of which are in the appropriate funds, required by local authorities to perform their functions and tasks in order to ensure economic and sociocultural development of the local community. Taking into attention the features of functioning of the main subjects of local finance for thorough study of the essence of local authorities’ financial resources, their main components are considered

    Full Text Available BACKGROUND: Maintenance gefitinib significantly prolonged progression-free survival (PFS compared with placebo in patients from eastern Asian with locally advanced/metastatic non-small-cell lung cancer (NSCLC after four chemotherapeutic cycles (21 days per cycle of first-line platinum-based combination chemotherapy without disease progression. The objective of the current study was to evaluate the cost-effectiveness of maintenance gefitinib therapy after four chemotherapeutic cycle's stand first-line platinum-based chemotherapy for patients with locally advanced or metastatic NSCLC with unknown EGFR mutations, from a Chinese health care system perspective. METHODS AND FINDINGS: A semi-Markov model was designed to evaluate cost-effectiveness of the maintenance gefitinib treatment. Two-parametric Weibull and Log-logistic distribution were fitted to PFS and overall survival curves independently. One-way and probabilistic sensitivity analyses were conducted to assess the stability of the model designed. The model base-case analysis suggested that maintenance gefitinib would increase benefits in a 1, 3, 6 or 10-year time horizon, with incremental $184,829, $19,214, $19,328, and $21,308 per quality-adjusted life-year (QALY gained, respectively. The most sensitive influential variable in the cost-effectiveness analysis was utility of PFS plus rash, followed by utility of PFS plus diarrhoea, utility of progressed disease, price of gefitinib, cost of follow-up treatment in progressed survival state, and utility of PFS on oral therapy. The price of gefitinib is the most significant parameter that could reduce the incremental cost per QALY. Probabilistic sensitivity analysis indicated that the cost-effective probability of maintenance gefitinib was zero under the willingness-to-pay (WTP threshold of $16,349 (3 × per-capita gross domestic product of China. The sensitivity analyses all suggested that the model was robust. CONCLUSIONS: Maintenance gefitinib

In the summer of 2015 we have collected and mapped the services of organizations with the function of economic development in the Hungarian city, Győr. Through our research we could identify the services and the characteristics of linkages and cooperation of the economic development organizations (EDOs. Most important findings of the study are the followings: activity of the organizations has a wide range. Some of them are presented in more organizations at the same time. Level of diversification is quite low. Directions of cooperation are mainly based on personal or ad hoc relations. We conducted that EDOs know about each other, despite of this fact the number of linkages is low. In this paper we provide findings about Győr, but the results can be used for other settlements’ economic development, too.

    Bovine respiratory disease is an economically important syndrome in the beef industry, and diagnostic accuracy is important for optimal disease management. The objective of this study was to determine whether improving diagnostic sensitivity or specificity was of greater economic value at varied levels of respiratory disease prevalence by using Monte Carlo simulation. Existing literature was used to populate model distributions of published sensitivity, specificity, and performance (ADG, carcass weight, yield grade, quality grade, and mortality risk) differences among calves based on clinical respiratory disease status. Data from multiple cattle feeding operations were used to generate true ranges of respiratory disease prevalence and associated mortality. Input variables were combined into a single model that calculated estimated net returns for animals by diagnostic category (true positive, false positive, false negative, and true negative) based on the prevalence, sensitivity, and specificity for each iteration. Net returns for each diagnostic category were multiplied by the proportion of animals in each diagnostic category to determine group profitability. Apparent prevalence was categorized into low (increasing specificity created more rapid, positive change in net returns than increasing sensitivity. Improvement of diagnostic specificity, perhaps through a confirmatory test interpreted in series or pen-level diagnostics, can increase diagnostic value more than improving sensitivity. Mortality risk was the primary driver for net returns. The results from this study are important for determining future research priorities to analyze diagnostic techniques for bovine respiratory disease and provide a novel way for modeling diagnostic tests.

Reading and writing are the most powerful modes of formal learning and they are fundamental to intellectual inquiry and creativity in all disciplines. Literacy comprises not only reading and writing skills but also understanding of human communication needs and the way of social functioning. The aim of this study was to determine the importance of foreign language learning for students’ socio-economic adaptation. The study investigated the relationship between students’ foreign language literacy and their achievements in medical studies.The investigation is a prospective study carried out among students of the Faculty of Medicine in Nis during June, 2006. The investigation included 312 students of all departments (medicine, dentistry, pharmacy and nursing and was conducted by means of a questionnaire. We determined students’ socio-economic adaptation, literacy in the mother tongue and foreign language (reading, writing, speaking and listening, and the ability of using modern technological achievements (computer work, Internet and SMS correspondence.Writing and listening skills of the mother tongue are significantly lower at the Department of Nursing. There is no difference in using post-correspondence among groups, whereby dentistry students most often used modern means of communication. The percentage of students satisfied with their social status is the highest among students of medicine and pharmacy and the lowest among students at the Department of Nursing. The percentage of students satisfied with the economic status is the highest among students of medicine, slightly lower among students of dentistry and pharmacy, and the lowest among nurses. The average grade of achievements at the Faculty is the highest in the group of nurses, slightly lower in the group of pharmacy, and the lowest in the group of medicine and dentistry.

    The aims of this study were (1) to assess the relationships between transport to and from school (active vs. passive), sedentary behaviours, measures of socio-economic position and perceived environmental variables, and (2) to determine which, if any, variables were predictors of active transportation. The sample comprised 705 girls with mean age of 14.7 (SD = 1.6) years old. Questionnaires were used to describe travel mode to school and to estimate weekly television and computer use (screen time). Girls were assigned to active transportation (AT) or passive transportation (PT) groups depending on whether they walked or bicycled (AT) to and from school or travelled by car or bus (PT). Screen time was determined by the number of hours they reported watching television and using computers in the week preceding the examination, including weekends. Socio-economic position was established by parental occupation and educational level. A questionnaire assessed Perceived Neighbourhood Environments. No statistically significant differences were seen for screen time between travel groups. Occupational status of both mother (r = -0.17) and father (r = -0.15) and father's educational level (r = -0.10) were significantly and negatively associated with AT, while street connectivity (r = 0.10) was positively and significantly associated with AT. Logistic regression analysis showed that the likelihood of active commuting decreased by around 50% with increasing father's occupation (odds ratio (OR) = 0.51; p active (OR = 1.63; p active commuting to school and that street connectivity is a predictor of active transportation in adolescent girls.

    Taking into consideration the influence of the media coverage, this research aims to analyze the characteristics of the local newspapers that cover diverse events relevant to nuclear energy in regional areas where nuclear facilities are located (hereinafter called the 'region'). According to the previous surveys, local residents in the region are more interested in the nuclear energy matters than those who live in urban areas. Plus, the local newspapers turn out to report more events of nuclear energy from a variety of angles. Through interviews with executives and journalists of the local newspaper companies in the regions, it is revealed that the local newspapers tend not to report news sensationally, but they would rather take a supportive stance toward the development in their regions. The interviewees hope that various activities of the nuclear industry will promote education, employment and cooperation among government, industry and academia. They also desire that the industry's activities will help to increase benefits in their regions. It appears that the interviewees' awareness reflects articles of the local newspapers. As a result of the surveys conducted for this research, it is considered that the journalists expect that their region will make particularly qualitative progress in the future. (author)

    The aim was to assess the health-related quality of life (HRQL) of the Roma and further to detect the significant determinants that are associated with their HRQL. The cross-sectional study involved 1068 Roma adults living in settlements (mean age 36). HRQL was measured by the Greek version of SF-36 Health Survey and further socio-demographic characteristics (sex, age, marital status, education, permanent occupation etc.) and housing conditions (stable housing, access to basic amenities such as drinkable water, drainage, electricity which compose material deprivation) were involved. Non parametric tests and multiple linear regression models were applied to identify the factors that have significant association with HRQL. After controlling for socio-demographic characteristics, health status and housing conditions, sex, age, education, chronic diseases, stable housing and material deprivation were found to be significant determinants of the Roma's HRQL. Men reported significantly better health than women as well as those who attended school compared to the illiterate. Chronic diseases were remarkably associated with poor HRQL from 10 units in MH (Mental Health) to 34 units in RP (Role Physical). Material deprivation was related to lower GH (General Health), and VT (Vitality) scores and higher RP (Role Physical) and RE (Role Emotional) scores. Chronic conditions and illiteracy are two key areas that contribute significantly to worse HRQL. Policies should be part of a comprehensive and holistic strategy for the Roma through intervention to education, housing and public health.

This work adds to published literature by exploring the external factors that affect companies’ location. It compares results obtained at municipal, county and LWM levels, and concludes that the latter show better the conglomerate levels and hence the effect of external factors on the territory. Results are identified, classified and compared using several indexes.

  18. Rapid recovery of genetic diversity of dogwhelk (Nucella lapillus L.) populations after local extinction and recolonization contradicts predictions from life-history characteristics.

    Colson, I; Hughes, R N

    2004-08-01

    The dogwhelk Nucella lapillus is a predatory marine gastropod populating North Atlantic rocky shores. As with many other gastropod species, N. lapillus was affected by tributyltin (TBT) pollution during the 1970s and 1980s, when local populations became extinct. After a partial ban on TBT in the United Kingdom in 1987, vacant sites have been recolonized. N. lapillus lacks a planktonic larval stage and is therefore expected to have limited dispersal ability. Relatively fast recolonization of some sites, however, contradicts this assumption. We compared levels of genetic diversity and genetic structuring between recolonized sites and sites that showed continuous population at three localities across the British Isles. No significant genetic effects of extinction/recolonization events were observed in SW Scotland and NE England. In SW England we observed a decrease in genetic diversity and an increase in genetic structure in recolonized populations. This last result could be an artefact, however, due to the superposition of other local factors influencing the genetic structuring of dogwhelk populations. We conclude that recolonization of vacant sites was accomplished by a relatively high number of individuals originating from several source populations (the 'migrant-pool' model of recolonization), implying that movements are more widespread than expected on the basis of development mode alone. Comparison with published data on genetic structure of marine organisms with contrasted larval dispersal supports this hypothesis. Our results also stress the importance of local factors (geographical or ecological) in determining genetic structure of dogwhelk populations. Copyright 2004 Blackwell Publishing Ltd

Materials and Methods: Day-old commercial broiler chicks (n=200 were distributed randomly into 5 dietary treatment groups viz. control (T1, probiotic in the feed @ 100 g/tonne of feed (T2, prebiotic in the feed @ 500 g/tonne of feed (T3, probiotic + prebiotic @ 100 g/tonne and 500 g/tonne of feed, respectively (T4 and probiotic + prebiotic @ 50 g/tonne and 250 g/tonne of feed (T5. The growth of broilers and dressing weight along with the weight of giblet (liver without gall bladder, gizzard without serous layer, and heart without pericardium, Kidney, Abdominal fat, Length of Intestine and dressing percentage were measured. Economics in terms of Return Over Feed Cost (ROFC and European Performance Efficiency Index (EPEI was calculated. Results: Among all carcass traits, dressing percentage, abdominal fat weight and abdominal fat percentage (as a percentage of dressed weight were recorded significant (p<0.05 difference among different treatment groups. The income from selling of the birds was significantly (p<0.05 higher in all treatment groups than the control group but there was a non-significant difference between supplemented groups. Feed cost during whole experimental period was significantly (p<0.05 lower in synbiotic supplemented groups (T4 and T5 than other groups. ROFC of all treatment group found significantly (p<0.05 higher than the control group. Conclusion: It can be concluded that the diet supplemented with synbiotic (100% level was most efficient in terms of EPEI and synbiotic (50% level in terms of ROFC. Hence, as feed supplement, synbiotic has a beneficial effect over probiotic and prebiotic when used alone.
