    BACKGROUND: Despite local control now exceeding 90% with image-guided adaptive brachytherapy (IGABT), regional and distant metastases continue to curb survival in locally advanced cervical cancer. As regional lymph nodes often represent first site of metastatic spread, improved nodal control could...... improve survival. The aim of this study was to examine optimal volume and dose of external beam radiotherapy (EBRT) to maximize regional control including dose contribution from IGABT. MATERIAL AND METHODS: In total 139 patients from the EMBRACE study were analyzed. Individual nodal dose was determined...

    Speech recognition starts with representations of basic acoustic perceptual features and ends by categorizing the sound based on long-term memory for word meaning. However, little is known about whether the reverse pattern of lexical influences on basic perception can occur. We tested for a lexical influence on auditory spatial perception by having subjects make spatial judgments of number stimuli. Four experiments used pointing or left/right 2-alternative forced choice tasks to examine perceptual judgments of sound location as a function of digit magnitude (1-9). The main finding was that for stimuli presented near the median plane there was a linear left-to-right bias for localizing smaller-to-larger numbers. At lateral locations there was a central-eccentric location bias in the pointing task, and either a bias restricted to the smaller numbers (left side) or no significant number bias (right side). Prior number location also biased subsequent number judgments towards the opposite side. Findings support a lexical influence on auditory spatial perception, with a linear mapping near midline and more complex relations at lateral locations. Results may reflect coding of dedicated spatial channels, with two representing lateral positions in each hemispace, and the midline area represented by either their overlap or a separate third channel.

    This document represents a first step in the process of developing comprehensive value-impact methodology for the nuclear industry. It describes the development of the methodology and includes a discussion of the uses of cost-benefit or value-impact by other industries. This background is provided as a guide to the development of the methodology for the specific problems confronted by the nuclear industry. The use of benefit-cost analysis, or value-impact analysis, within the nuclear power industry has grown in recent years and is relied upon by both the regulatory community and the regulated industry. This report summarizes the state of the art of value-impact analysis as it affects these users. Relevant past experience in such fields as water resource development, transportation, environmental concerns, and health and medicine is reviewed. A critique of the applicability of existing value-impact analysis methods to nuclear safety decision problems is presented

    Full Text Available People in most cultures would probably agree that politeness is needed during their interaction. However there may be differing opinions as to when they should be polite. In tourism industry, tourism service providers’ act as hosts and tourists act as guests. Typically hosts will try to act politely and use appropriate politeness norms when serving guests to ensure their satisfaction. The research findings show that the tourism service providers in Central Java use various unggah-ungguh ‘politeness norms’ when serving English speaking tourists and Indonesian speaking tourists. Besides that, there are some violations made by the tourism service providers in using unggah-ungguh ‘politeness norms’. The research findings also show that there are similar and different perspectives on unggah-ungguh ‘politeness norms’ between English speaking tourists with Western culture backgrounds and Indonesian speaking tourists with Indonesian culture backgrounds towards the politeness norms used by the tourism service providers in Central Java. The findings imply the needs of energizing unggah-ungguh ‘politeness norms’ which is discovered from well known noble Javanese values used by the tourism service providers for tourism service improvement.

  7. The societal impact value of risk

    1995-04-01

    A key ill-defined issue in the management and regulation of potentially hazardous conditions is that of the value to be associated with a reduction (or existence) of human health risks, such as radiation exposure or hazardous substance ingestion. Empirical observations of societal behavior patterns lead to a relationship for the quantitative value of societal risk impact which is consistent with general societal risk acceptance, is not inconsistent with ''de facto'' risk regulation, and is suitable and appropriate as a specification or guide for risk management and risk regulation. This societal risk impact expression is: Impact ($/year) = (8 x 10 7 ) NR i 4/3 where Ri = individual annual mortality risk; N = number of persons in the population sharing the risk and benefits. The change in Impact which can be derived from a regulation or risk management activity is the value of annual benefit which society would expect to forego (or annual equivalent cost to incur) in consideration of the activity

    The basic purpose of this handbook is to document a set of systematic procedures for providing information that can be used in performing value-impact assessments of Nuclear Regulatory Commission (NRC) regulatory actions. The handbook describes a structured but flexible process for performing the assessment. Chapter 1 is an introduction to the value-impact assessment process. Chapter 2 describes the attributes most frequently affected by proposed NRC actions, provides guidance concerningthe appropriate level of effort to be devoted to the assessment, suggests a standard format for documenting the assessment, and discusses the treatment of uncertainty. Chapter 3 contains detailed methods for evaluating each of the attributes affected by a regulatory action. The handbook has five appendixes containing background information, technical data, and example applications of the value-impact assessment procedures. This edition of the handbook focuses primarily on assessing nuclear power reactor safety issues

    2000-01-01

    The revised EC Patient Directive 97/43 EURATOM introduces the concepts of clinical audit, diagnostic reference levels and optimisation of radiation protection in diagnostic radiology. The application of reference dose levels in practice involves the establishment of reference dose values as actual measurable operational quantities. These values should then form part of an ongoing optimisation and audit programme against which routine performance can be compared. The CEC Quality Criteria for Radiographic Images provides guidance reference dose values against which local performance can be compared. In many cases these values can be improved upon quite considerably. This paper presents the results of a local initiative in the North West of the UK aimed at establishing local reference dose values for a number of major hospital sites. The purpose of this initiative is to establish a foundation for both optimisation strategies and clinical audit as an ongoing and routine practice. The paper presents results from an ongoing trial involving patient dose measurements for several radiological examinations upon the sites. The results of an attempt to establish local reference dose values from measured dose values and to employ them in optimisation strategies are presented. In particular emphasis is placed on the routine quality control programmes necessary to underpin this strategy including the effective data management of results from such programmes and how they can be employed to optimisation practices.

    Quinn, Sharon; Hickey, Deb

    The contemporary challenges associated with addressing diversity, ethnicity, equality and accessibility in today's healthcare economy, sometimes lead to a reactive response where service providers strive to apply these concepts in practice. This article describes establishing a group that could engage with the broadest spectrum of the local community in ways that would make a lasting and meaningful difference to the local population, including how individuals and groups engage with and access palliative care services. The Valuing Local Diversity in Palliative Care Group was formed in May 2006. The group, whose membership is composed of statutory and voluntary services and members of various community groups, has promoted some innovative and creative partnerships.

  15. Central $L$-values of elliptic curves and local polynomials

    Here we study the recently introduced notion of a locally harmonic Maass form and its applications to the theory of $L$-functions. In particular, we find finite formulas for certain twisted central $L$-values of a family of elliptic curves in terms of finite sums over canonical binary quadratic forms. This yields vastly simpler formulas related to work of Birch and Swinnerton-Dyer for such $L$-values, and extends beyond their framework to special non-CM elliptic curves.

  16. Statistical lamb wave localization based on extreme value theory

    Harley, Joel B.

    2018-04-01

    Guided wave localization methods based on delay-and-sum imaging, matched field processing, and other techniques have been designed and researched to create images that locate and describe structural damage. The maximum value of these images typically represent an estimated damage location. Yet, it is often unclear if this maximum value, or any other value in the image, is a statistically significant indicator of damage. Furthermore, there are currently few, if any, approaches to assess the statistical significance of guided wave localization images. As a result, we present statistical delay-and-sum and statistical matched field processing localization methods to create statistically significant images of damage. Our framework uses constant rate of false alarm statistics and extreme value theory to detect damage with little prior information. We demonstrate our methods with in situ guided wave data from an aluminum plate to detect two 0.75 cm diameter holes. Our results show an expected improvement in statistical significance as the number of sensors increase. With seventeen sensors, both methods successfully detect damage with statistical significance.

    Full Text Available This paper is aiming at revealing the existence of local wisdom values in Minangkabau through the representation of Minangkabau dance creation at present time in West Sumatera. The existence of the dance itself gives impact to the continuation of the existence of local value in West Sumatera. The research method was qualitative which was used to analyze local wisdom values in the present time Minangkabu dance creation representation through the touch of reconstruction and acculturation as the local wisdom continuation. Besides, this study employs multidisciplinary study as the approach of the study by implementing the sociology anthropology of dance and the sociology and anthropology of culture. Object of the research was Minangkabau dance creation in present time, while the data was collected through interview and direct observation, as well as documentation. The data was analyzed by following the technique delivered by Miles and Huberman. Research results showed that Minangkabau dance creation was a reconstruction result of the older traditional dance, and through acculturation which contains local wisdom values. The existence of Mianngkabau dance creation can affect the continuation of local wisdom values in Minangkabau society in West Sumatera. The existence of dance creation has maintained the Minangkabau local wisdom values in present time.

    1995-01-01

    Value-based benefits and costs of demand-side management (DSM) were discussed in the context of local electricity resource planning in downtown Toronto. The analysis considered the effects on local customer interruption as a result of DSM, and the deferment in need for local transmission and distribution upgrades. The life cycle and cash flow benefits and costs of DSM were discussed from the perspectives of the electric utility, the DSM-participating and non-participating customers, and society as a whole. Cashflow and lifecycle analyses results were reconciled. The Toronto Integrated Electrical Service (TIES) study, the basis for this paper, was described. Two main conclusions were reached, i.e. since the savings in the generationg system as a whole were far greater than the local savings,the value of a specific DSM program would be similar across a utility's service area, and (2) while cashflow analysis illustrated the short and medium term benefits and costs in a way most people intuitively understand, in effect,the lifecycle-cost estimates produce a clearer indicator of long-run economics

    The paper looks at the various non-radiological impacts of nuclear power stations on the environment which are grouped as ecological, amenity and socio-economic effects. The study and assessment of environment impacts are explained and comparisons made between those from nuclear and coal fired power stations. The prediction of future effects and judgement of their significance is difficult but is helped by the procedures evolved and by knowledge from the construction and operation of a large number of projects in physically different locations. Research is also needed into new issues and this must be recognised early. From experience of a number of nuclear stations it appears that the local impacts are acceptable provided care is taken.

  1. 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

    The management of stormwater runoff via distributed green infrastructures delivers a number of environmental services that go beyond the reduction of flood risk, which has been the focus of conventional stormwater systems. Not all of these services may be equally valued by the public, however. This paper estimates households' willingness to pay (WTP) for improvements in water security, stream health, recreational and amenity values, as well as reduction in flood risk and urban heat island effect. We use data from nearly 1000 personal interviews with residential homeowners in Melbourne and Sydney, Australia. Our results suggest that the WTP for the highest levels of all environmental services is A799 per household per year. WTP is mainly driven by residents valuing improvements in local stream health, exemptions in water restrictions, the prevention of flash flooding, and decreased peak urban temperatures respectively at A297, A244, A104 and A$65 per year. We further conduct a benefit transfer analysis and find that the WTP and compensating surplus are not significantly different between the study areas. Our findings provide additional support that stormwater management via green infrastructures have large nonmarket benefits and that, under certain conditions, benefit values can be transferred to different locations.

    Prospective observational study. To investigate the value of pain distribution in localizing appropriate surgical levels in patients with cervical spondylosis. Previous studies have investigated the value of pain drawings in its correlation with various features in degenerative spine diseases including surgical outcome, magnetic resonance imaging findings, discographic study, and psychogenic issues. However, there is no previous study on the value of pain drawings in identifying symptomatic levels for the surgery in cervical spondylosis. The study collected data from patients with cervical spondylosis who underwent surgical treatment between August 2009 and July 2012. Pain diagrams drawn separately by each patient and physician were collected. Pain distribution patterns among various levels of surgery were analyzed by the chi-square test. Agreement between different pairs of data, including pain diagrams drawn by each patient and physician, intra-examiner agreement on interpretation of pain diagrams, inter-examiner agreement on interpretation of pain diagrams, interpretation of pain diagram by examiners and actual surgery, was analyzed by Kappa statistics. The study group consisted of 19 men and 28 women with an average age of 55.2 years. Average duration of symptoms was 16.8 months. There was no difference in the pain distribution pattern at any level of surgery. The agreement between pain diagram drawn by each patient and physician was moderate. Intra-examiner agreement was moderate. There was slight agreement of inter-examiners, examiners versus actual surgery. Pain distribution pattern by itself has limited value in identifying surgical levels in patients with cervical spondylosis.

  4. Should Social Value Obligations be Local or Global?

    2017-02-01

    According to prominent bioethics scholars and international guidelines, researchers and sponsors have obligations to ensure that the products of their research are reasonably available to research participants and their communities. In other words, the claim is that research is unethical unless it has local social value. In this article, we argue that the existing conception of reasonable availability should be replaced with a social value obligation that extends to the global poor (and not just research participants and host communities). To the extent the social value requirement has been understood as geographically constrained to the communities that host research and the countries that can afford the products of research, it has neglected to include the global poor as members of the relevant society. We argue that a new conception of social value obligations is needed for two reasons. First, duties of global beneficence give reason for researchers, sponsors, and institutions to take steps to make their products more widely accessible. Second, public commitments made by many institutions acknowledge and engender responsibilities to make the products of research more accessible to the global poor. Future research is needed to help researchers and sponsors discharge these obligations in ways that unlock their full potential. Published 2017.

    2016-04-01

    Full Text Available The sustainability of food value chains is an increasing concern for consumers, food companies and policy-makers. Global food chains are often perceived to be less sustainable than local food chains. Yet, thorough food chain analyses and comparisons of different food chains across sustainability dimensions are rare. In this article we analyze the local Belgian and global Peruvian asparagus value chains and explore their sustainability performance. A range of indicators linked to environmental, economic and social impacts is calculated to analyze the contribution of the supply chains to economic development, resource use, labor relations, distribution of added value and governance issues. Our findings suggest that none of the two supply chains performs invariably better and that there are trade-offs among and between sustainability dimensions. Whereas the global chain uses water and other inputs more intensively and generates more employment per unit of land and higher yields, the local chain generates more revenue per unit of land.

    Let E be a real q-uniformly smooth Banach space. Suppose T is a set-valued locally strongly accretive map with open domain D(T) in E and that 0 is an element of Tx has a solution x* in D(T). Then there exists a neighbourhood B in D(T) of x* and a real number r 1 >0 such that for any r>r 1 and some real sequence {c n }, any initial guess x 1 is an element of B and any single-valued selection T 0 of T, the sequence {x n } generated from x 1 by x n+1 =x n -c n T 0 x n , n≥1, remains in D(T) and converges strongly to x* with ||x n -x*|| O(n -(q-1)/ q). A related result deals with iterative approximation of a solution of the equation f is an element of x+Ax when A is a locally accretive map. Our theorems generalize important known results and resolve a problem of interest. (author). 39 refs

    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.

    Purpose: To evaluate the values of ultrasound, CT and 99m Tc-MIBI in the localization of hyperfunctioning parathyroid tissue. Methods: 23 patients with primary hyperparathyroidism underwent 23 ultrasound, 20 CT scans and 21 double phase 99m Tc-MIBI imagings. Surgical and histological correlation was obtained for all studies. Results: 23 adenomas and 2 hyperplastic glands were removed from 23 patients. The results showed the sensitivities were 60%, 68%, 91%; the specificities were 97%, 97%, 100%; and the accuracies were 89%, 91%, 98% respectively with ultrasound, CT and 99m Tc-MIBI. There was no significant difference between ultrasound and CT (P > 0.05), but 99m Tc-MIBI was superior to ultrasound and CT in the sensitivity and accuracy, the specificity was similar for all of three imaging methods (P > 0.05). Conclusions: Double phase 99m Tc-MIBI imaging is a promising technique for localization of parathyroid adenomas. It is necessary for patients to undergo the noninvasive imaging procedures before their initial neck exploration

    2017-08-01

    Full Text Available Batik was incorporated into the Indonesian culture since the Majapahit era. At that time the royal families of Majapahit Kingdom wore batik clothes for activities such as religious event or kingdom event. Since then batik was seen as a symbol of nobility. The growth of batik industry especially in Yogyakarta and Surakarta region has produced a diverse motive and fabric quality of batik clothes. To help differentiate between these batik clothes the owner of batik industries created batik labels with intricate design. This study focused on analysing the intricate design and typography found within three batik labels each from Yogyakarta and Surakarta Region to better understand the role of local culture and values in creating the batik label design using vernacular typography and cultural approach. The result shows that the local culture and values symbolically enforced by each keraton kingdom-like body and social system in Yogyakarta and Surakarta influenced the batik label design. The high cultured values of Yogyakarta keraton resulted in a more formal and rigid typefaces used in the batik label giving off a classical feeling. Meanwhile the more grass rooted values of Surakarta urban culture resulted in a fluid and flowing typefaces giving off a trendy casual feeling.

  13. 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

  14. The Impact of Reputation on Market Value

    OpenAIRE

    2012-01-01

    Corporate reputations are one of the best known but least understood company assets. Few investment analysts would argue that they have no value but at the same time would struggle to put figures on how much. This paper dispels the myth that intangible means immeasurable. It provides an objective analysis of the scale of the shareholder value tied up in the reputations of many of the largest US and UK public companies. Moreover, it argues that critical understanding of the sources and drivers...

  15. The land value impacts of wetland restoration.

    U.S. regulations require offsets for aquatic ecosystems damaged during land development, often through restoration of alternative resources. What effect does large-scale wetland and stream restoration have on surrounding land values? Restoration effects on real estate values have substantial implications for protecting resources, increasing tax base, and improving environmental policies. Our analysis focuses on the three-county Raleigh-Durham-Chapel Hill, North Carolina region, which has experienced rapid development and extensive aquatic ecological restoration (through the state's Ecosystem Enhancement Program [EEP]). Since restoration sites are not randomly distributed across space, we used a genetic algorithm to match parcels near restoration sites with comparable control parcels. Similar to propensity score analysis, this technique facilitates statistical comparison and isolates the effects of restoration sites on surrounding real estate values. Compared to parcels not proximate to any aquatic resources, we find that, 1) natural aquatic systems steadily and significantly increase parcel values up to 0.75 mi away, and 2) parcels 0.5 mi from EEP sites gain substantial amenity value. When we control for intervening water bodies (e.g. un-restored streams and wetlands), we find a similar inflection point whereby parcels points to the need for higher public visibility of aquatic ecosystem restoration programs and increased public information about their value.

    The environment and the economy are inextricably linked. Today the environmental, economic, and social associated with project and program decisions are at times of such a magnitude and duration that they exceed our ability to understand, let alone mitigate them. Energy production, distribution, pricing, policies, end uses, and externalities demonstrate the need for wise planning and informed decision making. International cooperation, based upon mutually shared respect, responsibility, and innovative solutions is an essential component of addressing contemporary issues, impacts, and opportunities. Both egypt and the united states have laws requiring environmental impact assessments. Just as egypt can learn from our successes and failures in the environmental impact assessment field over the past 36 years, the united states and other nations can learn as egypt develops and innovates its own approaches and solutions

    B-cell leukemia 3 (Bcl-3) is a member of the inhibitor of κB family, which regulates a wide range of biological processes by functioning as a transcriptional activator or as a repressor of target genes. Elevated expression, sustained nuclear accumulation, and uncontrolled activation of Bcl-3 causes increased cellular proliferation or survival, dependent on the tissue and type of stimuli. We retrospectively reviewed patients who were diagnosed with colorectal cancer at Skåne University Hospital in Malmö between 1st of January 1990 and 31st of December 1991. Bcl-3 localization in colorectal cancer was assessed by immunohistochemistry on tissue microarray and freshly isolated colon from patients. Correlation between Bcl-3 localization and clinicopathological parameters of the cohort were evaluated using the Spearman rank-order correlation coefficient. In addition, Bcl-3 expression and localization in colon adenocarcinoma cells were analysed by western blot, immunohistochemistry and subcellular fractionation separately. We found that Bcl-3 was mainly localized in the cytoplasm in the tumour tissue isolated from colon cancer patients. Normal colon samples from the same patients showed Bcl-3 localization in the nucleus. In three out of six colon cancer cell lines, we detected elevated levels of Bcl-3. In these cell lines Bcl-3 was accumulated in the cytosol. We confirmed these findings by analysing Bcl-3 localization in a colon tissue micro array consisting of 270 cases. In these samples Bcl-3 localization correlated with the proliferation marker Ki-67, but not with the apoptotic marker Caspase 3. These findings indicate that analysis of the subcellular localization of Bcl-3 could be a potential-early diagnostic marker in colon cancer

    Full Text Available The paper presents empirical evidence about the impact of firm’s shareholders number as non accounting information on the value relevance of its earnings and book value of equity as accounting information for Jordanian industrial firms for the period from 1993 to 2002. Employing the return regression analysis and using shareholders number in two proxies namely local and foreign shareholders number, the findings of the study are fourfold. First, Individual earnings are value relevant while book value is irrelevant. Second, combining earnings with book value leads both of them to be irrelevant. Third, extending local shareholders number has significant impact on the value relevance of individual and combined earnings. Forth, extending foreign shareholders number has significant impact on the value relevance of individual book value and combined earnings. Since studies on the value relevance of these variables have neglected Jordan (and the Middle Eastern region, the study is the first especially in Jordan that tries to fill this gap by examiningthe impact of shareholders numbers on the value relevance of earnings and book valueto indicate firm value.

    Full Text Available The article argues for the universal character of human rights. It is demonstrated that they are not of specific value of Western culture but are a universal norm. This norm is valid not only for political practices but, first of all, for the morality and practice of argumentation. Human rights are strictly correlated with Kantian Categorical Imperative and can be substantiated by means of transcendental­pragmatic argument (K.­O. Apel. The difference between values and norms are also considered. It is demonstrated that values are always subjective and arbitrary meanwhile final justification is possible for norms.

  6. Local economic impacts associated with pure taxable capacity changes

    International Nuclear Information System (INIS)

    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

    Valuation of endangered species is important in many circumstances, and particularly when assessing the impact of large accidental oil spills. Previous studies have tested the effects of including in the contingent valuation survey reminders about the existence of diverse substitutes (in terms of other natural resources also in danger of extinction in the same area, other programs to be valued, or alternative uses of money). We include a reminder about the existence of the same biological species not being under danger of extinction elsewhere. We believe this reminder allows individuals to make an easy assessment of the biological scarcity of the species they are supposed to value. Thus, the key difference with previous studies is that valuation of endangered species is combined with an assessment of preferences towards conservation of local and native species. Our WTP results are not sensitive to the information provided about other foreign substitutes. Implications of this finding are discussed. (author)

    Consumer as final step of the value chain - The reorganization of the energy market, together with an increase in the mobility of resources and the evolution of supply, have reduced borders between national and local market, and both regulatory policies and players' strategies have to consider these renewed environment. The goal of this paper is to make some considerations about the dimension and the interactions between national and locals, up-stream and downstream energy markets, both in terms of value chain phases regulation and of the impact on firms' organization and on the industry as a whole. We want to highlight evident problems of coordination of different rules, the necessity to define a clear national industrial policy (not fragmented at local level), as well as the relevance of the end user prices regulation for liberalized market. In particular, this kind of regulation seems to represent a key point of the current discussion between operators and the energy Authority. The end users price regulation present some critical aspects related to its (contested) limited contribution to a real price competition but, on the other side, had to be considered as a strong protection for domestic customers, as well as a way to reduce information asymmetry.

    2009-01-01

    Local land use planning has profound impacts on environmental quality; however, few empirical studies have been conducted to systematically measure local land use plans' environmental assessment quality and to identify the factors influencing it. This paper analyzes the quality of 40 Environmental Impact Reports (EIRs) of local jurisdictions' land use plans in California. A plan evaluation protocol defined by five core components and sixty-three indicators is developed to measure the quality of local land use plans' EIRs. The descriptive results indicate that the local jurisdictions produce relatively good quality on its EIRs, but there is still much room for improvement. There are large variations in the quality of EIRs across local jurisdictions. The regression results further highlight three major factors that can significantly influence local land use plan's EIR quality: number of planners, plan updating ability, and development pressure

    Full Text Available This article addresses the issue on why Indonesian people cannot accept Lesbian, Gay, Bisexual, and Transgender (“LGBT”. Further, it also illustrates the reflection on how the society changes paradox in the era of globalisation. More concretely, which shows its willingness to uniform the social structure, at the same time attempts to preserve their own distinctive identity. Indonesian people who uphold Pancasila or five national ideologies would be a perfect example in this case. Pancasila, in this case, is a crystallization form of the values such as religious, social, and cultural realm which live within Indonesian society. As time passes, Pancasila is often grounded and contrasted to western cultural values like LGBT. The influx of LGBT thoughts which relies on the human rights concept spread a long time ago in Indonesia. However, this issue reemerges into the air, at the same time in different places and countries, becomes the vast spread of LGBT legalization such as in Europe and America. The resistance against Indonesian people, who mostly anti LGBT concept, is sparked by the influence of international human right law. These are recorded several times in Indonesia’s history. Attempts such as submitting judicial review in the Constitutional Court about the offense of adultery contained in the criminal law case, establishing the pro-LGBT legal communities, and gathering social supports are also conducted to convince Indonesian people to accept LGBT in the society. However, both society and government agree to take steps and synergize to stand firmly to drown this effort. Then, this article will also expose some scholars’ arguments, cases, jurisprudence, and journals to show the authors’ standing in this context.

    1985-01-01

    According to current Nuclear Regulatory Commission (NRC) procedures, value-impact (cost-benefit) assessments must be prepared for all rulemaking actions and for a broad range of other regulatory requirements and guidance. Probabilistic risk assessment (PRA) methods furnish an important part of the information base for these assessments. PRA methods are frequently the principal quantitative tool for estimating the benefits (e.g., public risk reduction) of proposed regulatory actions. In December 1983, the NRC published A Handbook for Value-Impact Assessment, NUREG/CR-3568, which provides a set of systematic procedures for performing value-impact assessments. The Handbook contains methods, data, and sources of information that can assist the regulatory analyst in conducting such assessments. The use of probabilistic risk analysis to estimate the benefits of proposed regulatory actions is described. Procedures and methods are also given for evaluating the costs and other consequences associated with regulatory actions. The Handbook has been adopted by the NRC as the recommended guideline for value impact assessments. This paper presents the background, objectives, and scope of the Handbook, describes the value-impact assessment methods (including the use of probabilistic risk assessment to estimate benefits), and discusses a selection of current and planned applications, with examples to illustrate how the methods are used

    2004-01-01

    High power spallation targets for neutron sources are being developed in the world. Mercury target will be installed at the material and life science facility in J-PARC, which will promote innovative science. The mercury target is subject to the pressure wave caused by the proton bombarding mercury. The pressure wave propagation induces the cavitation in mercury that imposes localized impact erosion damage on the target vessel. The impact erosion is a critical issue to decide the lifetime of the target. The electric Magnetic IMpact Testing Machine, MIMTM, was developed to produce the localized impact erosion damage and evaluate the damage formation. Acoustic vibration measurement was carried out to investigate the correlation between the erosion damage and the damage potential derived from acoustic vibration. It was confirmed that the damage potential related with acoustic vibration is useful to predict the damage due to the localized impact erosion and to diagnose the structural integrity. (author)

  3. Handling conflicting interests and values: how is the local partnership methodology helping to achieve it?

    International Nuclear Information System (INIS)

    Mormont, M.

    2004-01-01

    What the local partnership deals with is not the unavoidable conflicts between interests and values, but the way and the processes by which a new reality (waste disposal) can come into existence. This perspective is in line with other contemporary problems of 'coming into existence' of technical objects (GMO, cellular antennas, windmills, new drugs) that are alleged to induce dramatic social impacts. The local partnership methodology has three specific characteristics: a. it puts the emphasis on local capacities to integrate the siting process in a development process: this implies a priority given to local actors; b. it opens discussion on knowledge and techniques: this implies moving from the fear rhetoric to science (or risk) communication; c. it considers necessary trust not as a condition of the process but as a result of the process: this implies a new distribution of roles and leadership. As in any ongoing social innovation process, success cannot be promised, but some lessons can be drawn from what we may call social learning. As the objective is to arrive at a concerted choice that takes different values and interests into account, the technical object can be evaluated solely in terms of scenarios illustrating the constraints and the potentialities, technical and societal, offered by the object. These scenarios are collectively generated through discussion, and their characteristics can be revealed only through a process of exploration such as that facilitated by the local partnerships. In this perspective, a purely technical discussion could not lead to the identification of a perfect, or optimal, technique: such an approach could only lead to a Decide-Announce-Defend situation that today is no longer considered acceptable. On the other hand, no democratic procedure alone of deliberation or communication can resolve the conflicts of value and interest that are presented by the technical object. Only by treating in a single process the technical project

    Methods are developed for assessing the cost effectiveness of proposed systems and strategies for mitigating the consequences of severe nuclear accidents. Such mitigation systems consist mostly of devices for improving the ability of a reactor containment to survive such an accident and retain all radioactive materials. Value/impact analysis is applied to the system with and without mitigation, using the population dose averted by mitigation as the value of benefit, and the dollar cost of the containment improvements as the impact. Other considerations affecting such analyses include ways of monetizing public health risk, economic discounting, and the effect of interdiction policy and other post-accident recovery costs

    In this paper, a novel local value iteration adaptive dynamic programming (ADP) algorithm is developed to solve infinite horizon optimal control problems for discrete-time nonlinear systems. The focuses of this paper are to study admissibility properties and the termination criteria of discrete-time local value iteration ADP algorithms. In the discrete-time local value iteration ADP algorithm, the iterative value functions and the iterative control laws are both updated in a given subset of the state space in each iteration, instead of the whole state space. For the first time, admissibility properties of iterative control laws are analyzed for the local value iteration ADP algorithm. New termination criteria are established, which terminate the iterative local ADP algorithm with an admissible approximate optimal control law. Finally, simulation results are given to illustrate the performance of the developed algorithm.In this paper, a novel local value iteration adaptive dynamic programming (ADP) algorithm is developed to solve infinite horizon optimal control problems for discrete-time nonlinear systems.

    2010-04-01

    Digital radiography poses the risk of unnoticed increases in patient dose. Manufacturers responded to this by offering an exposure index (EI) value to clinicians. Use of the EI value in clinical practice is encouraged by the American College of Radiology and American Association of Physicists in Medicine. This study assesses the impact of processing delay on the EI value. An anthropormorphic phantom was used to simulate three radiographic examinations; skull, pelvis and chest. For each examination, the phantom was placed in the optimal position and exposures were chosen in accordance with international guidelines. A Carestream (previously Kodak) computed radiography system was used. The imaging plate was exposed, and processing was delayed in various increments from 30 seconds to 24 hours, representing common delays in clinical practice. The EI value was recorded for each exposure. The EI value decreased considerably with increasing processing delay. The EI value decreased by 100 within 25 minutes delay for the chest, and 20 minutes for the skull and pelvis. Within 1 hour, the EI value had fallen by 180, 160 and 100 for the chest, skull and pelvis respectively. After 24 hours, the value had decreased by 370, 350 and 340 for the chest, skull and pelvis respectively, representing to the clinician more then a halving of exposure to the detector in Carestream systems. The assessment of images using EI values should be approached with caution in clinical practice when delays in processing occur. The use of EI values as a feedback mechanism is questioned.

    Full Text Available Our paper focuses on the relevant theoretical economic approaches that allow us to understand the key elements of cultural values. The paper presents a model envisaged to estimate economic and social impact of modernization on cultural values in modern societies. We employ three indices of social and economic development for each level in Russian Federal districts of Moscow and St. Petersburg in order to reveal their impacts on modernization processes. Our data has been collected via the means of a questionnaire and an opinion poll with the purpose of revealing the value guidelines of society in terms of its modernization. Our results reveal the presence of four relevant levels of value orientations: family orientations, global, work, and personal orientations. Our results demonstrate how modernization is perceived in modern societies, in which spheres it is mostly expressed, and how it influences the society. Moreover, we show the determinants of values within four levels of value orientations. Our findings provide estimations of modern attitudes towards social consciousness in the processes of modernization and reveal basic moral principles that could become a background of new system of values used in modernizing modern societies.

  11. LOCAL COMMUNITY ATTITUDES TOWARDS THE IMPACT OF TOURISM ON PROSTITUTION

    Directory of Open Access Journals (Sweden)

    Anallely BELLO

    2011-12-01

    Full Text Available Tourism has been commonly related to prostitution. However, very few studies have evidenced this relationship in different contexts. Several studies on local community attitudes towards tourism impacts have briefly assessed the increase of prostitution as one of several indicators of social change. Due to the importance that such relationship has both for tourism impact management and social development, the impact of tourism on prostitution should be studied in detail. This study explores the ‘responsibility' of tourism on the increase of prostitution in an urban destination as perceived by local residents. It was found that while local community residents do not perceive tourism as the only causing factor, the tourist involvement in commercial sex does exist, but it is commonly an incidental rather than a purposive experience.

  12. The Value of Mainstreaming Human Rights into Health Impact Assessment

    Science.gov (United States)

    MacNaughton, Gillian; Forman, Lisa

    2014-01-01

    Health impact assessment (HIA) is increasingly being used to predict the health and social impacts of domestic and global laws, policies and programs. In a comprehensive review of HIA practice in 2012, the authors indicated that, given the diverse range of HIA practice, there is an immediate need to reconsider the governing values and standards for HIA implementation [1]. This article responds to this call for governing values and standards for HIA. It proposes that international human rights standards be integrated into HIA to provide a universal value system backed up by international and domestic laws and mechanisms of accountability. The idea of mainstreaming human rights into HIA is illustrated with the example of impact assessments that have been carried out to predict the potential effects of intellectual property rights in international trade agreements on the availability and affordability of medicines. The article concludes by recommending international human rights standards as a legal and ethical framework for HIA that will enhance the universal values of nondiscrimination, participation, transparency and accountability and bring legitimacy and coherence to HIA practice as well.

    2005-01-01

    This PowerPoint presentation examined the potential of oil and gas facilities to devalue land, with specific reference to a recent study conducted by the Alberta Energy and Utilities Board (EUB). Issues concerning the establishment of injurious affection were discussed, as well as devaluation's susceptibility to market-based analysis. Burdens of proof in injurious affection cases were discussed. Issues concerning compensation for devaluation in the event of oil and gas activities were reviewed, as well as various caveats and restrictive covenants. Issues concerning the EUB study of the impact of oil and gas activity on rural residential property values were examined. It was suggested that the study included too few properties with oil and gas facilities actually located on them to determine whether the impact on value was statistically significant. The magnitude of effects on values within the study were also counter-intuitive: wells further away had greater impact on values than wells nearby. In addition, times of sale did not appear to have been considered or adjusted for. Sale dates ranged from January 1994 to March 2001. It was concluded that there were a huge number of variables other than proximity of oil and gas facilities which could not be isolated or held constant in the evaluation of properties. tabs., figs

    To compare the clinic value between dentomaxillary pantomography and periapical radiographs in localization of the impacted teeth. 43 impacted teeth were localized with both dentomaxillary pantomography technique and periapical radiographs with horizontal tube shift which is clinically widely used. And a comparison between the two methods was carried out using Chi square test. Both dentomaxillary pantomography and periapical radiographs with horizontal tube shift can relatively precisely demonstrate the position of the impacted teeth. The percentage of the cases which the image and the result of surgery was consistent in the two methods was 93.02% and 95.35% (P>0.05) respectively. There was no statistical difference between the two groups. Dentomaxillary pantomography can precisely localize the impacted teeth.

    2010-08-01

    This paper presents gastrointestinal absorption fractions (f1 values) for estimating internal doses from local and regional fallout radionuclides due to nuclear tests. The choice of f1 values are based on specific circumstances of weapons test conditions and a review of reported f1 values for elements in different physical and chemical states. Special attention is given to fallout from nuclear tests conducted at the Marshall Islands. We make a distinction between the f1 values for intakes of radioactive materials immediately after deposition (acute intakes) and intakes that occur in the course of months and years after deposition, following incorporation into terrestrial and aquatic foodstuffs (chronic intakes). Multiple f1 values for different circumstances where persons are exposed to radioactive fallout (e.g., local vs. regional fallout and coral vs. continental tests) are presented when supportive information is available. In some cases, our selected f1 values are similar to those adopted by the International Commission on Radiological Protection (ICRP) (e.g., iodine and most actinides). However, f1 values for cesium and strontium derived from urine bioassay data of the Marshallese population are notably lower than the generic f1 values recommended by ICRP, particularly for acute intakes from local fallout (0.4 and 0.05 for Cs and Sr, respectively). The f1 values presented here form the first complete set of values relevant to realistic dose assessments for exposure to local or regional radioactive fallout.

  18. Minimization of local impact of energy systems through exergy analysis

    Cassetti, Gabriele; Colombo, Emanuela

    2013-01-01

    Highlights: • The model proposed aims at minimizing local impact of energy systems. • The model is meant to minimize the impact starting from system thermodynamics. • The formulation combines exergy analysis and quantitative risk analysis. • The approach of the model is dual to Thermoeconomics. - Abstract: For the acceptability of energy systems, environmental impacts are becoming more and more important. One primary way for reducing impacts related to processes is by improving efficiency of plants. A key instrument currently used to verify such improvements is exergy analysis, extended to include also the environmental externalities generated by systems. Through exergy-based analyses, it is possible indeed to evaluate the overall amount of resources consumed along all the phases of the life cycle of a system, from construction to dismantling. However, resource consumption is a dimension of the impact of a system at global level, while it may not be considered a measure of its local impact. In the paper a complementary approach named Combined Risk and Exergy Analysis (CRExA) to assess impacts from major accidents in energy systems is proposed, based on the combination of classical exergy analysis and quantitative risk analysis (QRA). Impacts considered are focused on effects on human health. The approach leads to the identification of solutions to minimize damages of major accidents by acting on the energy system design

    Knowles, W.M.C.; Dinnie, K.S.; Gordon, C.W.

    1992-01-01

    Like other nuclear utilities, Ontario Hydro, as part of its risk management activities, continually assesses the safety of its nuclear operations. In addition, new regulatory requirements are being applied to the older nuclear power plants. Both of these result in proposed plant modifications designed to reduce the risk to the public. However, modifications to an operating plant can have serious economic effects, and the resources, both financial and personnel, required for the implementation of these modifications are limited. Thus, all potential benefits and effects of a proposed modification must be thoroughly investigated to judge whether the modification is beneficial. Ontario Hydro has begun to use comprehensive value-impact assessments, utilizing plant-specific probabilistic risk assessments (PRAs), as tools to provide an informed basis for judgments on the benefit of safety-related modifications. The results from value-impact assessments can also be used to prioritize the implementation of these modifications

    Full Text Available Food festivals are a mainstay of the festival sector and some surveys show that they currently account for 30 percent. Despite this, we know very little about this important part of event tourism, and its economic and social impacts. This study tries to show, by econometric methods, the impacts on the local economy made by food festivals – and, at the same time, fhe effects -of the multiplicator and spillover factors. This paper looks for some correlation between the local index-number of tourism and gastronomic festivals, using data from more than 200 events and festivals and 123 settlements. The first step in the survey was to determine two tourism factors, and this was followed by our methodological studies of these factors. Although the summarized conclusions may not support the general opinion as can be found in the relevant literature – that is, a positive correlation between gastronomic festivals and local tourism, new research directions are revealed.

  4. Rainforest pharmacopeia in Madagascar provides high value for current local and prospective global uses.

    Directory of Open Access Journals (Sweden)

    Christopher D Golden

    Full Text Available Botanical diversity provides value to humans through carbon sequestration, air and water purification, and the provisioning of wild foods and ethnomedicines. Here we calculate the value of botanical ethnomedicines in a rainforest region of Madagascar, the Makira Protected Area, using a substitution method that combines replacement costs and choice modeling. The Makira watershed may comprise approximately 0.8% of global botanical diversity and possesses enormous value both in its ability to provision botanical ethnomedicines to local people and as a source of potentially novel pharmaceutical drugs for society as a whole. Approximately 241 locally-recognized species are used as ethnomedicines, including 113 agricultural or weed species. We equated each ethnomedicinal treatment to the monetary value of a comparable pharmaceutical treatment adjusted by personal preferences in perceived efficacy (rather than from known or assumed medicinal equivalency. The benefit value of these botanical ethnomedicines per individual is $5.40-7.90 per year when using the value of highly subsidized Malagasy pharmaceuticals and $100.60-287.40 when using the value of American pharmaceuticals. Using local pharmaceuticals as substitutes, the value per household is $30.24-44.30 per year, equivalent to 43-63% of median annual household income, demonstrating their local importance. Using the value of American pharmaceuticals, the amount is equivalent to 22-63% of the median annual health care expenditures for American adults under 45 in 2006. The potential for developing novel biomedicines from the Makira watershed's unique flora ranges in untapped benefit value from $0.3-5.7 billion for American pharmaceutical companies, non-inclusive of the importance of providing novel medicines and improved healthcare to society. This study provides evidence of the tremendous current local and prospective global value of botanical ethnomedicines and furthers arguments for the

    To evaluate the diagnostic value of oblique coronal reconstructed CT images to determine the local invasion of advanced gastric cancer (AGC). Thirty-four consecutive patients, who were suspected to have locally invasive advanced gastric cancer (more than T3 stage) on a preoperative MDCT scan and underwent a diagnostic or curative laparotomy, were enrolled in this study. Two reviewers performed an independent blind review of three series of MDCT images in random order; axial (AXI), conventional coronal (CCI), and oblique coronal (OCI) (parallel to long axis of gastric body and pancreas) images. In assessing the local invasion, the reader's confidence for the local invasion of AGC was graded using a five point scale (1 = definitely negative, 5 = definitely positive: T4). With surgical findings and histopathological proofs as reference standards, the diagnostic performance of the three different plans of CT images was employed for the verification of local invasion of AGC on a preoperative CT scan using the receiver operating characteristic (ROC) method. Agreements between the two reviewers were analyzed using weighted kappa statistics. Results: In 19 out of 34 patients, local invasion was confirmed surgically or histopathologically (13 pancreas invasion, 6 liver invasion, 4 major vascular invasion, 3 colon and mesocolon invasion, and 2 spleen invasion). The diagnostic performance of OCI was superior to AXI or CCI in the local invasion of AGC. The differences in the area under the curve of AXI (0.770 {+-} 0.087, 0.700 {+-} 0.094), CCI (0.884 {+-} 0.058, 0.958 {+-} 0.038), and OCI (0.954 {+-} 0.050, 0.956 {+-} 0.049), were statistically significant for both reviewers. Inter-observer agreement was excellent for OCI ({kappa}= .973), which was greater than CCI (({kappa}= .839), and AXI (({kappa}= .763). On a CT scan, OCI might be a useful imaging technique in evaluating locally invasive advanced gastric cancer.

    1996-01-01

    3-D Seismic has had a profound and lasting impact on the hydrocarbon exploration and production industry. It is a technology which is often excellent at assessing the risk associated with trap definition, seal and reservoir distribution, the very parameters which are the most critical to optimizing the economics associated with E and P projects. This paper discusses Amoco Corporation's experience with 3-D Seismic when used for new field rate acceleration, older field extension, and wildcat exploration. Its emphasis is on assessing the value added by 3-D by reviewing recent E and P experiences in a post-appraisal mode and then in applying the lessons learned from these analyses and case histories to potential new projects. This work is significant because it first assesses the impact 3-D has had on a large number of business situations at Amoco; that is, it is based on data collected on159 3-D surveys acquired at Amoco between 1991--1994. Second, it uses the data collected from these surveys and applies the business improvements observed in the data to typical international business opportunities to quantify, in expected value $ terms, the value that the technology brings to an average project. Finally, it looks at project economics not only from an oil company perspective, but from the standpoint of a host government, with a discussion of insights and implications of the data, economics and techniques utilized

  9. Impact localization in dispersive waveguides based on energy-attenuation of waves with the traveled distance

    Science.gov (United States)

    Alajlouni, Sa'ed; Albakri, Mohammad; Tarazaga, Pablo

    2018-05-01

    An algorithm is introduced to solve the general multilateration (source localization) problem in a dispersive waveguide. The algorithm is designed with the intention of localizing impact forces in a dispersive floor, and can potentially be used to localize and track occupants in a building using vibration sensors connected to the lower surface of the walking floor. The lower the wave frequencies generated by the impact force, the more accurate the localization is expected to be. An impact force acting on a floor, generates a seismic wave that gets distorted as it travels away from the source. This distortion is noticeable even over relatively short traveled distances, and is mainly caused by the dispersion phenomenon among other reasons, therefore using conventional localization/multilateration methods will produce localization error values that are highly variable and occasionally large. The proposed localization approach is based on the fact that the wave's energy, calculated over some time window, decays exponentially as the wave travels away from the source. Although localization methods that assume exponential decay exist in the literature (in the field of wireless communications), these methods have only been considered for wave propagation in non-dispersive media, in addition to the limiting assumption required by these methods that the source must not coincide with a sensor location. As a result, these methods cannot be applied to the indoor localization problem in their current form. We show how our proposed method is different from the other methods, and that it overcomes the source-sensor location coincidence limitation. Theoretical analysis and experimental data will be used to motivate and justify the pursuit of the proposed approach for localization in a dispersive medium. Additionally, hammer impacts on an instrumented floor section inside an operational building, as well as finite element model simulations, are used to evaluate the performance of

    Data on sea and groundwater levels, precipitation, land subsidence, geology, and geotechnical soil properties are combined with information on flood and erosion protection measures to analyze water-related impacts from climate change at an exposed coastal location. Future sea extremes will have a large impact but several coupled effects in the hydrological system need to be considered as well to provide for optimal protection and mitigation efforts. For instance, the investment and maintenance costs of securing functional water and wastewater pipes are significantly reduced by incorporating knowledge about climate change. The translation of regional sea level rise evidence and projections to concrete impact measures should take into account the potentially affected stakeholders who must collaborate on common and shared adaptation solutions. Here, knowledge integration across levels of governance and between research, private and public institutions, and the local communities provides: understanding of the immediate and potential future challenges; appreciation of different stakeholder motives, business agendas, legislative constraints etc., and a common focus on how to cost-efficiently adapt to and manage impacts of climate change. By construction of a common working platform that is updated with additional data and knowledge, e.g. from future regional models or extreme events, advances in sea level research can more readily be translated into concrete and local impact measures in a way that handles uncertainties in the future climate and urban development as well as suiting the varying stakeholder needs.

    Full Text Available The article makes a critical analysis of the impacts of the Brazilian Seed Law (10.711/2003 on agricultural biodiversity and on traditional and local agriculture. The above-mentioned law caters to the needs and interests of 'formal' seed systems, and does not consider the important role played by local and traditional seed systems (frequently called 'informal', in which the production, exchange, breeding and conservation of seeds are carried out by the farmers themselves, through their social networks and according to local rules. 'Formal' seed systems tend to focus mainly on crops of commercial value, and widely used in homogeneous environments. Therefore, they are not interested in producing seeds that are adapted to specific local conditions and uses, nor in attending the needs of local and traditional farmers, which have limited resources and live in regions that are culturally and environmentally heterogeneous.

This uniqueness was generally a positive value to maintain the harmony of human beings and nature. The discussion of this article was the verbal communication, the study of the wisdom of the nation speech-language Indonesia, and local wisdom in civilization. The words expressed in the local wisdom among others are fearless (need fear only God Almighty, self-sacrificing or spirit of nationalism (patriotism, orderly, loyal, affectionate, hardworking, consensus, mutual help, and creative. Positive values here needed to be crystallized in people’s lives; it would be the identifier of the Indonesian people. This research was conducted in five districts of Pagaralam, South Sumatra. The method used was qualitative. Data collection techniques included participant observer/observation, observation without participation, in-depth interviews, and documentation. This article finds that if local wisdom actually exists in everyday life, the nation of Indonesia has carved beauty behave in civilization itself. The local wisdom of the nation begins values, the rule in the family, and then developed in the community. A positive value of local wisdom is the identifier of civilized society and the need to preserve Indonesia.

    2017-10-01

    Theorists of politics of presence postulate that women elected to political office would still hold values similar to ordinary women and therefore represent them better than male politicians. Gender differences in personal values, which underline and give coherence to core political values, have been found among voters: males score higher on self-enhancement values (power and achievement) and females higher on self-transcendence values (universalism and benevolence). Our study aims to explore if gender differences in personal values are still present among activists, local and national politicians. We administer a shortened version of the Portrait Values Questionnaire to 233 Italian national politicians (46% females), 425 local politicians (56% females), 626 political activists (44% females), and 3249 ordinary citizens (49% females). Our results confirm only partially politics of presence theory: females at all levels of political involvement score higher in self-transcendent values that emphasise concern for the welfare of others, but no significant gender differences emerge for self-enhancement, which favour the pursuit of self-interest. Our findings support ethical struggles for more balanced gender representation: a higher proportion of women in politics could strengthen the political representation of self-transcendence values. © 2015 International Union of Psychological Science.

    Tufenkjian, Krikor; Lüders, Hans O

    2012-12-01

    Epilepsy surgery has become an important treatment option in patients with medically refractory epilepsy. The ability to precisely localize the epileptogenic zone is crucial for surgical success. The tools available for localization of the epileptogenic zone are limited. Seizure semiology is a simple and cost effective tool that allows localization of the symptomatogenic zone which either overlaps or is in close proximity of the epileptogenic zone. This becomes particularly important in cases of MRI negative focal epilepsy. The ability to video record seizures made it possible to discover new localizing signs and quantify the sensitivity and specificity of others. Ideally the signs used for localization should fulfill these criteria; 1) Easy to identify and have a high inter-rater reliability, 2) It has to be the first or one of the earlier components of the seizure in order to have localizing value. Later symptoms or signs are more likely to be due to ictal spread and may have only a lateralizing value. 3) The symptomatogenic zone corresponding to the recorded ictal symptom has to be clearly defined and well documented. Reproducibility of the initial ictal symptoms with cortical stimulation identifies the corresponding symptomatogenic zone. Unfortunately, however, not all ictal symptoms can be reproduced by focal cortical stimulation. Therefore, the problem the clinician faces is trying to deduce the epileptogenic zone from the seizure semiology. The semiological classification system is particularly useful in this regard. We present the known localizing and lateralizing signs based on this system.

    A methodology was developed to facilitate the selection of favorable thermal power plant site and design alternatives from the community perspective. A two-stage, multicriteria decision technique was employed to combine technical assessments of effects of the proposed site/design alternatives with corresponding community values. In the first stage, submodels are used to develop indices of plant impact on each of ten decision criteria. These criteria include effects on aesthetics, water quality, cost of power, air quality, ecology, social quality, local economy, recreational opportunities, cultural resources, and human health and safety. In the second stage, each of the impact indices is weighted by corresponding community values and then summed to provide an overall index of plant acceptability

    CHRISTUS Health began implementation of computer workstation single sign-on (SSO) in 2015. SSO technology utilizes a badge reader placed at each workstation where clinicians swipe or "tap" their identification badges. To assess the impact of SSO implementation in reducing clinician time logging in to various clinical software programs, and in financial savings from migrating to a thin client that enabled replacement of traditional hard drive computer workstations. Following implementation of SSO, a total of 65,202 logins were sampled systematically during a 7day period among 2256 active clinical end users for time saved in 6 facilities when compared to pre-implementation. Dollar values were assigned to the time saved by 3 groups of clinical end users: physicians, nurses and ancillary service providers. The reduction of total clinician login time over the 7day period showed a net gain of 168.3h per week of clinician time - 28.1h (2.3 shifts) per facility per week. Annualized, 1461.2h of mixed physician and nursing time is liberated per facility per annum (121.8 shifts of 12h per year). The annual dollar cost savings of this reduction of time expended logging in is $92,146 per hospital per annum and $1,658,745 per annum in the first phase implementation of 18 hospitals. Computer hardware equipment savings due to desktop virtualization increases annual savings to $2,333,745. Qualitative value contributions to clinician satisfaction, reduction in staff turnover, facilitation of adoption of EHR applications, and other benefits of SSO are discussed. SSO had a positive impact on clinician efficiency and productivity in the 6 hospitals evaluated, and is an effective and cost-effective method to liberate clinician time from repetitive and time consuming logins to clinical software applications.

    Health impact assessment (HIA) is a multidisciplinary aid to decision-making that assesses the impact of policy on public health and on health inequalities. Its purpose is to assist decision-makers to maximize health gains and to reduce inequalities. The 1999 Gothenburg Consensus Paper (GCP) provides researchers with a rationale for establishing community participation as a core value of HIA. According to the GCP, participation in HIA empowers people within the decision-making process and redresses the democratic deficit between government and society. Participation in HIA generates a sense that health and decision-making is community-owned, and the personal experiences of citizens become integral to the formulation of policy. However, the participatory and empowering dimensions of HIA may prove difficult to operationalize. In this review of the participation strategies adopted in key applications of HIA in the United Kingdom, we found that HIA's aim of influencing decision-making creates tension between its participatory and knowledge-gathering dimensions. Accordingly, researchers have decreased the participatory dimension of HIA by reducing the importance attached to the community's experience of empowerment, ownership and democracy, while enlarging its knowledge-gathering dimension by giving pre-eminence to "expert" and "research-generated" evidence. Recent applications of HIA offer a serviceable rationale for participation as a means of information gathering and it is no longer tenable to uphold HIA as a means of empowering communities and advancing the aims of participatory democracy.

  5. Corrections to the apparent value of the cosmological constant due to local inhomogeneities

    Supernovae observations strongly support the presence of a cosmological constant, but its value, which we will call apparent, is normally determined assuming that the Universe can be accurately described by a homogeneous model. Even in the presence of a cosmological constant we cannot exclude nevertheless the presence of a small local inhomogeneity which could affect the apparent value of the cosmological constant. Neglecting the presence of the inhomogeneity can in fact introduce a systematic misinterpretation of cosmological data, leading to the distinction between an apparent and true value of the cosmological constant. We establish the theoretical framework to calculate the corrections to the apparent value of the cosmological constant by modeling the local inhomogeneity with a ΛLTB solution. Our assumption to be at the center of a spherically symmetric inhomogeneous matter distribution correspond to effectively calculate the monopole contribution of the large scale inhomogeneities surrounding us, which we expect to be the dominant one, because of other observations supporting a high level of isotropy of the Universe around us. By performing a local Taylor expansion we analyze the number of independent degrees of freedom which determine the local shape of the inhomogeneity, and consider the issue of central smoothness, showing how the same correction can correspond to different inhomogeneity profiles. Contrary to previous attempts to fit data using large void models our approach is quite general. The correction to the apparent value of the cosmological constant is in fact present for local inhomogeneities of any size, and should always be taken appropriately into account both theoretically and observationally

    2017-12-01

    A real estate development often produces negative impacts towards the environment such as the reduction of the ecological capacity in the site and its surroundings, energy exploitation, and excessive pollutant emission. To overcome these issues, the green building concept or approach has been adapted by several real estate businesses in Indonesia especially in the office sector. According to the data provided by GBCI in 2017, there are 17 buildings listed as a certified green building office in various levels. As what has been known, the green building approach results in the increase of price in the planning, construction and the building's maintenance. This paper will discuss about the research results regarding the effect of the green building approach towards the property value of office buildings especially in Jakarta. The research will be executed through the comparison method, which is the process of comparing office building that have already adapted the green building concept with the one that have not, or in other words, the conventional office buildings. Data gathering is done through observation and interviews with developers and building managers. The research results show that by adapting the green building approach for office buildings in Jakarta, the property value regarding the utility, scarcity, effective demands, and transferability aspect can increase.

    This paper addresses the issue of the impact of the siting of nuclear facilities on the adjacent communities. It reviews previous studies on the issue and then empirically examines the impacts of seven major nuclear facilities located throughout the USA on the surrounding communities. The analysis focuses on the effects on local property values, economic growth, tax revenues, public services, community development, jobs and employment, and schools. Using published data, economic and statistical analyses, literature reviews and interviews, it finds that the impacts of these facilities have been largely positive. The findings are placed in perspective, caveats are noted concerning the generalisation of the conclusions derived and recommendations for required further research are provided. (author)

  8. Construction of extremal local positive-operator-valued measures under symmetry

    2003-01-01

    We study the local implementation of positive-operator-valued measures (POVMs) when we require only the faithful reproduction of the statistics of the measurement outcomes for all initial states. We first demonstrate that any POVM with separable elements can be implemented by a separable superoperator, and develop techniques for calculating the extreme points of POVMs under a certain class of constraint that includes separability and positive partial transposition. As examples we consider measurements that are invariant under various symmetry groups (Werner, isotropic, Bell diagonal, local orthogonal), and demonstrate that in these cases separability of the POVM elements is equivalent to implementability via local operations and classical communication (LOCC). We also calculate the extrema of these classes of measurement under the groups that we consider, and give explicit LOCC protocols for attaining them. These protocols are hence optimal methods for locally discriminating between states of these symmetries. One of many interesting consequences is that the best way to locally discriminate Bell-diagonal mixed states is to perform a two-outcome POVM using local von Neumann projections. This is true regardless of the cost function, the number of states being discriminated, or the prior probabilities. Our results give the first cases of local mixed-state discrimination that can be analyzed quantitatively in full, and may have application to other problems such as demonstrations of nonlocality, experimental entanglement witnesses, and perhaps even entanglement distillation

    The municipal council of Borsele considers that the use of nuclear energy is a question of national policy, but considers itself responsible for town and country planning, safety and employment. The two latter aspects are especially significant if plans for shutdown are concerned. Confidence in safety of the NPP in Borsele has increased in recent years due to transparent information policy of the power plant itself as well as the local government and most of the employees living in the area. If considering the circumstances under which the decision about the closure of NPP one could sees this is a purely political decision. The local government will continue the close cooperation with the National government and the Parliament in solving the problem of employment and social impact of NPP shutdown

    than the combinations of factors listed by the experts. In some instances, their understanding even appeared to be seriously flawed. In contemporary Xhosa society, ecological knowledge is unevenly spread and held by individuals rather than by groups. Therefore, it is important to work with experts rather than randomly selected individuals in ecological studies that incorporate local knowledge. Expert local knowledge adds value to science by providing detailed insights into the ultimate causes of change, and by contributing a rare historical perspective. Scientists add value to local knowledge through their ability to study and predict obscure processes such as the impact of atmospheric change on vegetation. Scientists must, however, acknowledge that positivist studies that compare local knowledge to science are fraught with ethical and methodological challenges. Certain aspects of local knowledge, particularly in terms of fire, are sacred and do not have the same origins as Western science. Local knowledge and science can complement one another, but we advise against integrating them in a way that co-opts local knowledge for scientific purposes.

    Full Text Available As the protected area mandate expands to include social equity, the impacts of parks and their tourism on neighbouring indigenous and local communities is receiving growing practical and theoretical interest. This article reported on one such study, which explored the impacts of protected area tourism on communities bordering the iconic Kruger National Park in South Africa and Purnululu National Park in Australia. The study drew on interviews with park staff, tourism operators and community members. Guided by a conceptual framework grounded in resilience thinking, interactions amongst the parks, tourism and local communities were revealed as complex, contested and multi-scalar. Underlying drivers included cultural norms and values based on nature, entrenched poverty, poor Western education and economic opportunities associated with tourism. Park tourism offered intrinsic opportunities and benefits from nature conservation and associated intangible cultural values. More tangible benefits arose through employment. Damage-causing animals and visitation difficulties were negative impacts. Interaction with tourists was limited, with a sense of disconnect evident. Findings indicated the need for multifaceted, carefully considered policy responses if social equity and benefits for local communities are to be achieved. Framing the impacts of protected area tourism through the resilience framework provided a useful way to access local community perceptions whilst retaining awareness of the broader multi-scalar context in which interactions occur. Conservation implications: Perceptions of separation and lack of education to engage in economic opportunities are major issues. Intrinsic appreciation of parks is an important platform for building future opportunities. Accrual of future benefits for local communities from park tourism depends on developing diverse economic opportunities, building community capacity and managing expectations and addressing

    Globalization is a key challenge facing health policy-makers. A significant dimension of this is trade in health services. Traditionally, the flow of health services exports went from North to South, with patients travelling in the opposite direction. This situation is changing and a number of papers have discussed the growth of health services exports from Southern countries in its different dimensions. Less attention has been paid to assess the real scope of this trade at the global level and its potential impact at the local level. Given the rapid development of this area, there are little empirical data. This paper therefore first built an estimate of the global size and of the growth trend of international trade in health services since 1997, which is compared with several country-based studies. The second purpose of the paper is to demonstrate the significant economic impact of this trade at the local level for the exporting country. We consider the case of health providers in the South-Mediterranean region for which the demand potential, the economic effects and the consequence for the health system are presented. These issues lead to the overall conclusion that different policy options would be appropriate, in relation to the nature of the demand. Copyright © 2014 Elsevier Ireland Ltd. All rights reserved.

    2009-07-01

    While the era of dam building is largely over in the United States, globally dams are still being proposed and constructed. The articles in this special issue consider many aspects and impacts of dams around the world. This paper examines dam removal and the measurement of the impacts of dams on local community property values. Valuable lessons may be found. In the United States, hundreds of small hydropower dams will come up for relicensing in the coming decade. Whether or not the licenses are renewed and what happens to the dams if the licenses expires is a subject of great debate. Dams are beginning to be removed for river restoration and fisheries restoration and these "end-of-life" decisions may offer lessons for countries proposing or currently building small (and large) hydropower dams. What can these restoration stories tell us? In this paper, we examine the effects of dams along the Penobscot River in Maine (USA) on residential property values. We compare the results to findings from a similar (but ex post dam removal) data set for properties along the Kennebec river in Maine, where the Edwards Dam was removed in 1999. The Penobscot River Restoration Project, an ambitious basin-wide restoration effort, includes plans to remove two dams and decommission a third along the Penobscot River. Dam removal has significant effects on the local environment, and it is reasonable to anticipate that environmental changes will themselves be reflected in changes in property values. Here we examine historical real estate transaction data to examine whether landowners pay a premium or penalty to live near the Penobscot River or near a hydropower generating dam. We find that waterfront landowners on the Penobscot or other water bodies in our study area pay approximately a 16% premium for the privilege of living on the water. Nevertheless, landowners pay LESS to live near the Penobscot River than they do to live further away, contrary to the expectation that bodies of water

    Living values are the principles and beliefs that influence the way of life and behavior of people in society. These values are defined to determine the individuals’ characteristics in the physical, intellectual, social-emotional, and spiritual dimensions. Such values could be acquired through physics learning. Therefore, the study concerned here was aimed at determining the difference in the living values acquired between students of the grade officially termed Grade X at a state senior high school referred to as SMAN 1 Selomerto, Central Java, Indonesia, who learned physics by using content based on local potentials and those who learned physics without using that content. A quasi-experiment with the control group pre-test post-test design was conducted to collect the data. The data were analyzed by using tests of normality, homogeneity, and different. The results indicate no difference in the living values acquired between students learning physics by using local-potential content and those learning physics without using that content.

  16. Restoring local spiritual and cultural values in science education: The case of Ethiopia

    Faris, Solomon Belay

    It has been repeatedly observed that home and local context matter in the education of children. A smooth transition between home and classroom prepares children for enjoyable and meaningful life-long learning. Knowledge building in children is influenced by previous experience, values, beliefs and sociocultural factors associated with community. Against this theoretical background, the thesis examined the integration of local spiritual and cultural values to improve science education in Ethiopia. This autoethnographic research used in-depth interviews, supplementary observations and focus group discussion and my biography to identify the perception and practice of common and unique spiritual and cultural values. The study examined whether these values were included and/or excluded in the school curriculum and explored the possibilities for incorporating values in science education and the anticipated tensions resulting from their inclusion. Students, science teachers, parents, employers, curriculum experts, policymakers, elders, and religious leaders participated in the research, conducted in a randomly selected secondary school in Addis Ababa. The sampling followed a kind of snowball method, with a total of twenty key informants participating in interviews, fifteen classroom observations, and one focus group discussion. The data collection aimed at generating stories, which underlie the auto-ethnography methodology. Findings indicated that belief in and fear of God animated and sustained the Ethiopian way of life. Although spiritual teachings derived from sacred writings were the initial foundation for Ethiopian cultural norms, the two merged together later, creating a mosaic pervading every aspect of life in Ethiopia. Education was sustained on this merger of spiritual and cultural norms and values. It was also shown that the now century-old system of formal education did not incorporate those local spiritual and cultural values. Current science education also

    Introduced species have contributed to extinction of native vertebrates in many parts of the world. Changes to vertebrate assemblages are also likely to alter microbial communities through coextinction of some taxa and the introduction of others. Many attempts to restore degraded habitats involve removal of exotic vertebrates (livestock and feral animals) and reintroduction of locally extinct species, but the impact of such reintroductions on microbial communities is largely unknown. We used high-throughput DNA sequencing of the fungal internal transcribed spacer I (ITS1) region to examine whether replacing exotic vertebrates with reintroduced native vertebrates led to changes in soil fungal communities at a reserve in arid central Australia. Soil fungal diversity was significantly different between dune and swale (interdune) habitats. Fungal communities also differed significantly between sites with exotic or reintroduced native vertebrates after controlling for the effect of habitat. Several fungal operational taxonomic units (OTUs) found exclusively inside the reserve were present in scats from reintroduced native vertebrates, providing a direct link between the vertebrate assemblage and soil microbial communities. Our results show that changes to vertebrate assemblages through local extinctions and the invasion of exotic species can alter soil fungal communities. If local extinction of one or several species results in the coextinction of microbial taxa, the full complement of ecological interactions may never be restored. © 2015 John Wiley & Sons Ltd.

    2018-03-01

    Many applications including optimal design and adaptive discretization techniques involve solving several boundary value problems on geometries that are local perturbations of an original geometry. This manuscript presents a fast direct solver for boundary value problems that are recast as boundary integral equations. The idea is to write the discretized boundary integral equation on a new geometry as a low rank update to the discretized problem on the original geometry. Using the Sherman-Morrison formula, the inverse can be expressed in terms of the inverse of the original system applied to the low rank factors and the right hand side. Numerical results illustrate for problems where perturbation is localized the fast direct solver is three times faster than building a new solver from scratch.

Under the dynamic capabilities view of the firm, this paper proposes a model that presents an exhaustive analysis of two relevant research gaps: (i the underlying relationships that determine the impact exerted by each of the four organizational culture typologies, comprised in Cameron and Quinn’s Competing Values Framework on organizational agility and, (ii the contingency effect exerted by a key environmental factor, the industry’s technology intensity. An empirical study is performed to test the relationships proposed, using data collected from 172 Spain-based companies. To examine the contingency effect of technology intensity, the sample is divided into two subsamples, high and medium tech companies. This work uses partial least squares path-modeling, a variance-based structural equations modeling technique, in order to test and validate the research model and hypotheses posited. In addition, thorough analyses are carried out to assess the predictive performance of our model.

    Pay-for-performance programs are often aimed to improve the management of chronic diseases. We evaluate the impact of a local pay for performance programme (QOF+), which rewarded financially more ambitious quality targets ('stretch targets') than those used nationally in the Quality and Outcomes Framework (QOF). We focus on targets for intermediate outcomes in patients with cardiovascular disease and diabetes. A difference-in-difference approach is used to compare practice level achievements before and after the introduction of the local pay for performance program. In addition, we analysed patient-level data on exception reporting and intermediate outcomes utilizing an interrupted time series analysis. The local pay for performance program led to significantly higher target achievements (hypertension: p-value <0.001, coronary heart disease: p-values <0.001, diabetes: p-values <0.061, stroke: p-values <0.003). However, the increase was driven by higher rates of exception reporting (hypertension: p-value <0.001, coronary heart disease: p-values <0.03, diabetes: p-values <0.05) in patients with all conditions except for stroke. Exception reporting allows practitioners to exclude patients from target calculations if certain criteria are met, e.g. informed dissent of the patient for treatment. There were no statistically significant improvements in mean blood pressure, cholesterol or HbA1c levels. Thus, achievement of higher payment thresholds in the local pay for performance scheme was mainly attributed to increased exception reporting by practices with no discernable improvements in overall clinical quality. Hence, active monitoring of exception reporting should be considered when setting more ambitious quality targets. More generally, the study suggests a trade-off between additional incentive for better care and monitoring costs.

    2017-01-15

    Biosphere reserves have been studied around the world, but methods to elicit community's values, worldviews and perceptions are missing. A greater understanding of these can help avoid tension and improve successful management. This paper used a mixed-methods survey to elicit local community's environmental values, ecological world views and perceptions of the Galloway and Southern Ayrshire Biosphere Reserve (GSABR). Over three weeks, forty participants from three communities of the GSABR responded to a semi-structured mixed-methods survey. The survey revealed that residents of the GSABR greatly value wildlife and beauty of nature, and that the majority of the respondents showed concern for the environment from an ecocentric worldview. Results also revealed that the most influential tested socio-demographic characteristic affecting people's relationship to their environment is their professional affiliation. Tourism and recreation were seen as major benefits of the recent biosphere designation. Results did highlight contrasting benefits from the designation for different stakeholder groups, which could potentially lead to tensions and should be considered in the reserve management. Given the community's supportive world views and perceptions, greater participation in the biosphere's management in likely to be welcomed and should be used to avoid or mediate any conflicts. The mixed-method survey developed for this study, proved successful in eliciting these themes in the GSABR. We recommend other biosphere reserves replicate this research, to gain better understanding of local communities and increase their support and participation in reserve management.

    Hundreds of chemicals are contact allergens but there remains a need to identify and characterise accurately skin sensitising hazards. The purpose of this review was fourfold. First, when using the local lymph node assay (LLNA), consider whether an exposure concentration (EC3 value) lower than 100% can be defined and used as a threshold criterion for classification and labelling. Second, is there any reason to revise the recommendation of a previous ECETOC Task Force regarding specific EC3 values used for sub-categorisation of substances based upon potency? Third, what recommendations can be made regarding classification and labelling of preparations under GHS? Finally, consider how to integrate LLNA data into risk assessment and provide a rationale for using concentration responses and corresponding no-effect concentrations. Although skin sensitising chemicals having high EC3 values may represent only relatively low risks to humans, it is not possible currently to define an EC3 value below 100% that would serve as an appropriate threshold for classification and labelling. The conclusion drawn from reviewing the use of distinct categories for characterising contact allergens was that the most appropriate, science-based classification of contact allergens according to potency is one in which four sub-categories are identified: 'extreme', 'strong', 'moderate' and 'weak'. Since draining lymph node cell proliferation is related causally and quantitatively to potency, LLNA EC3 values are recommended for determination of a no expected sensitisation induction level that represents the first step in quantitative risk assessment. 2009 Elsevier Inc.

    Biosimilar drugs are highly similar to an originator (reference) biologic, with no clinically meaningful differences in terms of safety or efficacy. As biosimilars offer the potential for lower acquisition costs versus the originator biologic, evaluating the economic implications of the introduction of biosimilars is of interest. Budget impact analysis (BIA) is a commonly used methodology. This review of published BIAs of biosimilar fusion proteins and/or monoclonal antibodies identified 12 unique publications (three full papers and nine congress posters). When evaluated alongside professional guidance on conducting BIA, the majority of BIAs identified were generally in line with international recommendations. However, a lack of peer-reviewed journal articles and considerable shortcomings in the publications were identified. Deficiencies included a limited range of cost parameters, a reliance on assumptions for parameters such as uptake and drug pricing, a lack of expert validation, and a limited range of sensitivity analyses that were based on arbitrary ranges. The rationale for the methods employed, limitations of the BIA approach, and instructions for local adaptation often were inadequately discussed. To understand fully the potential economic impact and value of biosimilars, the impact of biosimilar supply, manufacturer-provided supporting services, and price competition should be included in BIAs. Alternative approaches, such as cost minimization, which requires evidence demonstrating similarity to the originator biologic, and those that integrate a range of economic assessment methods, are needed to assess the value of biosimilars.

    Sphericity has been proposed as a parameter for characterizing PET tumour volumes, with complementary prognostic value with respect to SUV and volume in both head and neck cancer and lung cancer. The objective of the present study was to investigate its dependency on tumour delineation and the resulting impact on its prognostic value. Five segmentation methods were considered: two thresholds (40% and 50% of SUV max ), ant colony optimization, fuzzy locally adaptive Bayesian (FLAB), and gradient-aided region-based active contour. The accuracy of each method in extracting sphericity was evaluated using a dataset of 176 simulated, phantom and clinical PET images of tumours with associated ground truth. The prognostic value of sphericity and its complementary value with respect to volume for each segmentation method was evaluated in a cohort of 87 patients with stage II/III lung cancer. Volume and associated sphericity values were dependent on the segmentation method. The correlation between segmentation accuracy and sphericity error was moderate (|ρ| from 0.24 to 0.57). The accuracy in measuring sphericity was not dependent on volume (|ρ| value, although lower than that of volume, except for that derived using FLAB for which when combined with volume showed a small improvement over volume alone (hazard ratio 2.67, compared with 2.5). Substantial differences in patient prognosis stratification were observed depending on the segmentation method used. Tumour functional sphericity was found to be dependent on the segmentation method, although the accuracy in retrieving the true sphericity was not dependent on tumour volume. In addition, even accurate segmentation can lead to an inaccurate sphericity value, and vice versa. Sphericity had similar or lower prognostic value than volume alone in the patients with lung cancer, except when determined using the FLAB method for which there was a small improvement in stratification when the parameters were combined.

    2006-01-01

    We study the expectation values of Wilson-loop operators with the insertions of local operators Z J and Z-bar J for large J from the bulk viewpoint of AdS/CFT correspondence. Classical solutions of strings attached to such deformed Wilson loops at the conformal boundary are constructed and are applied to the computation of Wilson-loop expectation values. We argue that in order to have such solutions for general insertions at finite positions in the base spacetime of the gauge theory, it is crucial to interpret the holographic correspondence in the semi-classical picture as a tunneling phenomenon, as has been previously established for holographic computations of correlators of BMN operators. This also requires to use the Euclideanized AdS background and Euclidean super Yang-Mills theory

    Twelve mature local sheep, with a mean body weight of 49.2±3 kg were randomly distributed into three digestibility trail groups to evaluate the effects of inclusion some oils industry by-products, soft fatty acid (SFA) and hard fatty acid (HFA) on dry matter intake, digestibility coefficients, nutritive values, nitrogen and energy utilization and some rumen and blood parameters. The experimental diets were basal diet un-supplemented (control) or supplemented 3% SFA (T1) and 3% HFA (T2). The results showed that non-significant differences in total dry matter intake and water consumption among the tested diets were observed.The digestibility of dry matter (DM), organic matter (OM) and nitrogen free extract (NFE) were significantly increased (P<0.05) by addition of SFA while digestibility of crude protein (CP) and ether extract (EE) was significantly increased (P<0.05) by addition of HFA as compared with control. However, digestibility of crude fiber (CF) was significantly decreased (P<0.05) in T2 as compared with control and T1. Fatty acids supplementation significantly increased (P<0.05) the nutritive values such as TDN, SV and DCP as compared with control.The nitrogen utilization was significantly improved (P<0.05) by the addition of both additives. The values of total volatile fatty acid concentrations (TVFA) and pH values after feeding were significantly increased (P<0.05) with HFA supplementation as compared with the values of other groups. However, the rumina l ammonia-N concentrations after feeding significantly decreased (P<0.05) with fatty acids supplementation as compared with control. The results of digestible and metabolizable energy showed non-significant differences between the tested groups. Blood serum urea, albumen, cholesterol, triglycerides and phosphorus values were significantly increased (P<0.05) with HFA as compared with the values of other groups.The mean values of serum alanine transaminase (ALT), aspartate transaminase (AST

    Background: Preoperative chemo radiotherapy improves the prognosis of locally advanced low rectal cancer and induces a pathological response in the tumor, which may have prognostic value. Aim: To assess the results of rectal cancer treatment according to the degree of pathological response of the tumor after chemo radiotherapy. Patients and Methods: All patients with a locally advanced rectal cancer located within 11 cm of the rectal margin, subjected to preoperative chemo radiotherapy followed by surgical treatment in a period of 13 years, were included. Pathological response was classified as complete, intermediate and poor. The tumor was staged according to TNM 2002 classification. Survival was analyzed with Kaplan Meier curves and Cox regression. Results: Patients were followed for a mean of 50 months (range 18-156). Exclusive and global local relapse was observed in 3 and 9.6% of patients, respectively. Pathological response was complete in 13 patients (none died), intermediate in 23 (three died) and poor in 68 (22 died). Global five years survival was 74%. There was a concordance of 0.64 between survival and pathological response. The concordance between survival and TNM classification was 0.69. Conclusions: The pathological response of the tumor to chemo radiotherapy has a good concordance with prognosis, although it is not superior to the final pathological status

    Full Text Available The hygrothermal comfort indoor conditions are defined as: those environmental conditions in which an individual exposed, expresses a state of satisfaction. These conditions cannot always be achieved anywhere in an optimal way and economically; in some cases they can be obtained only in work environments specific areas. This could be explained because of air conditioning systems designing is generally performed both on the basis of the fundamental parameters’ average values, such as temperature, velocity and relative humidity (Ta, va e φa and derived parameters such as operating temperature and mean radiant one (Top eTmr. However, in some specific cases - large open-spaces or in case of radiating surfaces - the descriptors defining indoor comfort conditions, based on average values, do not provide the optimum values required during the air conditioning systems design phase. This is largely due to the variability of real environmental parameters values compared to the average ones taken as input in the calculation. The results obtained in previous scientific papers on the thermal comfort have been the driving element of this work. It offers a simple, original and clever way of thinking about the new domotic systems for air conditioning, based on the “local mean radiant temperature.” This is a very important parameter when one wants to analyze comfort in environments characterized by the presence of radiating surfaces, as will be seen hereinafter. In order to take into account the effects of radiative exchanges in the open-space workplace, where any occupant may find themselves in different temperature and humidity conditions, this paper proposes an action on the domotic climate control, with ducts and vents air distribution placed in different zones. Comparisons were performed between the parameters values representing the punctual thermal comfort, with the Predicted Mean Vote PMV, in an environment marked by radiating surfaces (i

    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.

    Full Text Available Land Surface Temperature (LST as provided by remote sensing onboard satellites is a key parameter for a number of applications in Earth System studies, such as numerical modelling or regional estimation of surface energy and water fluxes. In the case of Moderate Resolution Imaging Spectroradiometer (MODIS onboard Terra or Aqua, pixels have resolutions near 1 km 2 , LST values being an average of the real subpixel variability of LST, which can be significant for heterogeneous terrain. Here, we use Landsat 7 LST decametre-scale fields to evaluate the temporal and spatial variability at the kilometre scale and compare the resulting average values to those provided by MODIS for the same observation time, for the very heterogeneous Campus of the University of the Balearic Islands (Mallorca, Western Mediterranean, with an area of about 1 km 2 , for a period between 2014 and 2016. Variations of LST between 10 and 20 K are often found at the sub-kilometre scale. In addition, MODIS values are compared to the ground truth for one point in the Campus, as obtained from a four-component net radiometer, and a bias of 3.2 K was found in addition to a Root Mean Square Error (RMSE of 4.2 K. An indication of a more elaborated local measurement strategy in the Campus is given, using an array of radiometers distributed in the area.

    Full Text Available This research aims to study the market response to the aggressiveness of financial reporting and tax reporting conducted by the company. Investor’s response is reflected in the market value of the company's stock. This study is an explanatory research using quantitative approach. Research’s sample is a manufacturing company listed on the Indonesian stock exchanges from 2005 to 2015. The data were analyzed using multiple regression analysis. The data show that majority of sample companies’ fall into the category of middle tax aggressiveness. Research’s findings are both aggressive financial reporting and tax aggressiveness has a negative relationship with the market value of the company. However, only aggressive financial reporting that has a significant influence on the firm value. Based on these results it is concluded that tax aggressiveness does not directly affect the market in making decisions to assess the company's stock.

    The impact of localized microwave hyperthermia (2.45 GHz) on the tissue pH-distribution was investigated in C3H mause mammary tumors. The measurements were performed in microareas of the tissue using pH-microelectrodes with tip diameters of approximately 1 μm. pH-readings during localized heating revealed that tissue temperatures exceeding 42 0 C were followed by a pronounced pH-drop in tumors with a negligible amount of necrosis. Tissue pH-values measured immediately after heating (43 0 C for 60 min) were lowered by an average of 0.54 +- 0.19 pH-units as compared with preheating data (2p [de

    A thorough quantitative understanding of the processes of mercury emissions, deposition, and translocation through the food chain is currently not available. Complex atmospheric chemistry and dispersion models are required to predict concentration and deposition contributions, and aquatic process models are required to predict effects on fish. There are uncertainties in all of these predictions. Therefore, the most reliable method of understanding impacts of coal-fired power plants on Hg deposition is from empirical data. A review of the literature on mercury deposition around sources including coal-fired power plants found studies covering local mercury concentrations in soil, vegetation, and animals (fish and cows (Lopez et al. 2003)). There is strong evidence of enhanced local deposition within 3 km of the chlor-alkali plants, with elevated soil concentrations and estimated deposition rates of 10 times background. For coal-fired power plants, the data show that atmospheric deposition of Hg may be slightly enhanced. On the scale of a few km, modeling suggests that wet deposition may be increased by a factor of two or three over background. The measured data suggest lower increases of 15% or less. The effects of coal-fired plants seem to be less than 10% of total deposition on a national scale, based on emissions and global modeling. The following summarizes our findings from published reports on the impacts of local deposition. In terms of excesses over background the following increments have been observed within a few km of the plant: (1) local soil concentration Hg increments of 30%-60%, (2) sediment increments of 18-30%, (3) wet deposition increments of 11-12%, and (4) fish Hg increments of about 5-6%, based on an empirical finding that fish concentrations are proportional to the square root of deposition. Important uncertainties include possible reductions of RGM to Hg(0) in power plant plumes and the role of water chemistry in the relationship between Hg

    Full Text Available The process of socio-educational territorialisation in rural contexts is the topic of this text. 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.

We study the behaviour of algorithms with very low localities. Despite of this restriction we propose local constant ratio approximation algorithms for solving minimum dominating and connected dominating set, maximum independent set and minimum vertex cover in location aware Unit Disk Graphs. We also prove the first ever lower bounds for local algorithms for these problems with a given locality in the location aware setting.

    The environmental radiological impact assessment methodology includes a large number of parameters to simulate the environmental transfer and population exposure. Local and regional data are often not available, particularly for tropical regions, which leads to the use of literature data, mostly determined at temperate climate countries. Since 1993, IRD has been developing radioecological studies aiming the determination soil-plant transfer factors, which showed the possibility of finding values up to one order of magnitude higher than those found at temperate climate countries literature. This paper compares dose results for several scenarios, using regional and literature data, assessing the relevance of using site specific data for radiological impact assessments, for both practices and intervention situations.

    2015-12-01

    Three Gorges Project (TGP) is the largest hydroelectric project in the world and has led to significant land cover changes in Three Gorges Reservoir Area (TGRA). Since its construction the debates on its environmental and climatic impacts have never stopped, especially after the extreme drought and flood in Yangtze River Basin these years. TGP reached its final impounding water level in 2010. However, studies on systematically monitoring the long-term variations in surface and atmospheric parameters in TGRA are still lacking. In this study, three important surface parameters - surface albedo, land surface temperature (LST) and evapotranspiration (ET) and two climatic parameters - air temperature and precipitation were investigated from 2000 to 2013 by combining multiple remote sensing data and ground measurements. Results showed that along the reservoir albedo decreased significantly as a result of water impounding. Correspondingly, in the same region daytime LST decreased in spring and summer and nighttime LST increased in autumn and winter. In the western region of TGRA, albedo increased due to resettlement and LST also changed. The average ET increased by 20% in TGR but kept stable in the whole TGRA. In contrast to LST, air temperature showed less apparent spatial and temporal variability. Only in the region near the dam air temperature experienced a decrease at daytime and an increase at nighttime. Further analysis demonstrated precipitation revealed no apparent changes in TGRA and the precipitation anomaly in northwest of TGRA may not be connected with TGP. All of the findings provide a more substantial clues of local climate change caused by TGP.

  9. Boundary value problems of finite elasticity local theorems on existence, uniqueness, and analytic dependence on data

    1988-01-01

    In this book I present, in a systematic form, some local theorems on existence, uniqueness, and analytic dependence on the load, which I have recently obtained for some types of boundary value problems of finite elasticity. Actually, these results concern an n-dimensional (n ~ 1) formal generalization of three-dimensional elasticity. Such a generalization, be­ sides being quite spontaneous, allows us to consider a great many inter­ esting mathematical situations, and sometimes allows us to clarify certain aspects of the three-dimensional case. Part of the matter presented is unpublished; other arguments have been only partially published and in lesser generality. Note that I concentrate on simultaneous local existence and uniqueness; thus, I do not deal with the more general theory of exis­ tence. Moreover, I restrict my discussion to compressible elastic bodies and I do not treat unilateral problems.

    There is considerable controversy regarding policy and climate change mitigation in Africa. Its resolution will require integrating local knowledge and values into climate impact assessments. Africa's vulnerability to climate change can be traced to the frequency of socio-ecological devastation that comes from major climate variations on the continent. The incidence of famines, homelessness and disease epidemics that require international assistance are reflections of weak policies and institution action frames used to cope with climate and weather related emergencies. However, the valuation of climate change impacts has a subjective dimension that can be gained only through indigenous experience and an understanding of values associated with life-saving intervention programs. A recent study showed that discount rates applied to future life-saving programs by Africans are very different from the rates applied in developed countries, and that the difference should be reflected in national development programs and transnational initiatives for capacity building. The study suggests that if the boundary institutions responsible for public health security have not been too effective in resolving the policy controversy surrounding Africa's participation in climate change assessments, it is due partly to the limitations imposed by cross-scale issues in framing. It was concluded that efforts to reduce Africa's dependence on global emergency health response systems will necessitate the development of autonomous capacity to adapt to natural disasters. Appropriate frame reflection is needed at the local level. 56 refs., 3 tabs., 1 fig.

  11. Environment and energy in Iceland: A comparative analysis of values and impacts

    2007-01-01

    Within an Icelandic framework plan for energy, environmental values and impacts were estimated in multicriteria analyses for 19 hydroelectric and 22 geothermal developments. Four natural environment classes were defined (geology + hydrology, species, ecosystems + soils, landscape + wilderness) with cultural heritage as the fifth class. Values and impacts were assessed through 6 agglomerated attributes: richness/diversity, rarity, size/continuity/pristineness, information/symbolic value, international responsibility and visual value. The project offers a unique opportunity for comparing environmental values and impacts within a large sample of sites and energy alternatives treated within a common methodological framework. Total values were higher in hydroelectric than in geothermal areas. Hydroelectric areas scored high for cultural heritage (particularly in rarity and information value), landscape and wilderness. Geothermal areas had high bedrock and hydrological diversity and information values, and a high landscape visual value but little cultural heritage. High values were correlated among some classes of the natural environment, all of which are likely to reflect functional relationships. In contrast, cultural heritage values were not related to natural environment values. Overall, landscape and wilderness had the highest mean value and were also most affected by energy development. Over 40% of the hydroelectric development had a predicted mean impact value of > 4 (out of a maximum of 10), compared with 10% of the geothermal projects. Excluding two outsized hydropower options, there was a significant correlation between plant capacity and impact on geology and hydrology but not with other environmental variables

    In this paper we investigate the relationship between Funding Value Adjustment (FVA) and Net Stable Funding Ratio (NSFR). FVA is defined in a consistent way with NSFR such that the new framework of FVA monitors the costs due to keeping NSFR at an acceptable level, as well. In addition, the problem of choosing the optimal funding strategy is formulated as a shortest path problem where the proposed FVA framework is applied in the optimization process. The solution provides us with the optimal f...

  14. Wind versus coal: Comparing the local economic impacts of energy resource development in Appalachia

    International Nuclear Information System (INIS)

    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 The recent determination of the local value of the Hubble constant by Riess et al., 2016 (hereafter R16 is now 3.3 sigma higher than the value derived from the most recent CMB anisotropy data provided by the Planck satellite in a ΛCDM model. Here we perform a combined analysis of the Planck and R16 results in an extended parameter space, varying simultaneously 12 cosmological parameters instead of the usual 6. We find that a phantom-like dark energy component, with effective equation of state w=−1.29−0.12+0.15 at 68% c.l. can solve the current tension between the Planck dataset and the R16 prior in an extended ΛCDM scenario. On the other hand, the neutrino effective number is fully compatible with standard expectations. This result is confirmed when including cosmic shear data from the CFHTLenS survey and CMB lensing constraints from Planck. However, when BAO measurements are included we find that some of the tension with R16 remains, as also is the case when we include the supernova type Ia luminosity distances from the JLA catalog.

    Full Text Available Bioactive peptide from casein play a very important role in biological functionalities such as antioxidant and antimicrobial activities. Casein is the main protein that derived from goat milk which consists of alpha (α, beta (β and kappa (κ casein. Dietary protein such as casein from animal can provide rich source of bioactive peptide. However, the macromolecular protein such as cow milk can cause allergic response to certain individuals. On the other hand, goat milk have been known for its hypoallergenic and therapeutic properties in human nutrition and health. The purpose of this study is to extract casein from local breed goat milk and identify the molecular characterization of casein for nutraceutical value. The casein was successfully extracted using extraction method. Extraction is a common technique used to separate a desired substance when it is mixed with other components. The average percentage of casein obtained was 24.25%. Then, the casein was analysed by running it in the SDS-Page. The major fraction is β-casein and the minor is α-casein that can be seen between 20kDa and 30kDa respectively. There is no contaminated protein appear in the purified α-amylase. The result obtained in this study indicates that isolated casein from Malaysian goat milk was pure and can be used as bioactive peptide for nutraceutical value.

    Full Text Available This paper tests the performance of the Capital Asset Pricing Model (CAPM and the Fama-French three-factor and Carhart four-factor models on the Polish market. We use stock level data from April 2001 to January 2014 and find strong evidence for value and momentum effects, but only weak evidence for size premium. We formed portfolios double-sorted on size and book-to-market ratios, as well as on size and momentum, and we explain their returns with the above-mentioned asset pricing models. The CAPM is rejected and the three-factor and four-factor models perform well for the size and B/M sorted portfolios, but fail to explain returns on the size and momentum sorted portfolios. With the exception of the momentum factor, local Polish factors are not correlated with their European and global counterparts, suggesting market segmentation. Finally, the international value, size and momentum factors perform poorly in explaining cross-sectional variation in stock returns on the Polish market.

    SNARK, a member of the AMPK-related kinases, has been involved in the cellular stress responses but its precise mechanisms remain unclear. Subcellular localization of SNARK protein was identified. Unlike cytoplasmic localizing AMPKα, SNARK was predominantly localized in the nucleus. SNARK was constitutively distributed in the nucleus even when SNARK was activated by metabolic stimuli such as AICAR and glucose-deprivation. Conserved nuclear localization signal (NLS) was identified at the N-terminal portion ( 68 KKAR 71 ). Deletion and point mutation of this part resulted in the cytoplasmic translocation of mutant proteins. Furthermore, GFP fused with the SNARK fragment containing 68 KKAR 71 translocated to the nucleus. A microarray analysis revealed that the nuclear localizing SNARK altered transcriptome profiles and a considerable part of these alterations were canceled by the mutation of NLS, suggesting the ability of SNARK to modulate gene expression dependent on its nuclear localization.

    Health states defined by multiattribute instruments such as the EuroQol five-dimensional questionnaire with five response levels (EQ-5D-5L) can be valued using time trade-off (TTO) or discrete choice experiment (DCE) methods. A key feature of the tasks is the order in which the health state dimensions are presented. Respondents may use various heuristics to complete the tasks, and therefore the order of the dimensions may impact on the importance assigned to particular states. To assess the impact of different EQ-5D-5L dimension orders on health state values. Preferences for EQ-5D-5L health states were elicited from a broadly representative sample of members of the UK general public. Respondents valued EQ-5D-5L health states using TTO and DCE methods across one of three dimension orderings via face-to-face computer-assisted personal interviews. Differences in mean values and the size of the health dimension coefficients across the arms were compared using difference testing and regression analyses. Descriptive analysis suggested some differences between the mean TTO health state values across the different dimension orderings, but these were not systematic. Regression analysis suggested that the magnitude of the dimension coefficients differs across the different dimension orderings (for both TTO and DCE), but there was no clear pattern. There is some evidence that the order in which the dimensions are presented impacts on the coefficients, which may impact on the health state values provided. The order of dimensions is a key consideration in the design of health state valuation studies. Copyright © 2016. Published by Elsevier Inc.

    Full Text Available A growing concern among the manufacturers who are actively involved in Information Technology outsourcing is post-contract management and the ensuing development of what many practitioners have coined the ‘outsourcing partnership’. Over the past few decades, information technology outsourcing has become a widely used and researched means for manufacturers to enhance their performance. Increasing attention has been paid to building successful partnerships in information systems outsourcing. This study employs strategic social positioning, customer participation, customer orientation, and communication culture to develop research model. The quantitative method will be used to validate the research model and test hypotheses developed. This study uses survey method to collect data, and analysis of the reliability, validity and test the proposed hypotheses by Smart Partial Least Squares. The purpose of this study is to use above four factors to produce value co-creation between outsourcing vendors and manufacturers. The final aim is for the future collaboration. This combination will allow manufacturers and information technology outsourcing vendors to increase their value co-creations in the fields of these factors.

    2012-11-01

    Full Text Available Infrastructures, through externalities, modify the territorial status quo: by creating advantages and disadvantages, they lead to inequalities and territorial cohesion problems, calling for a setup of territorial equalization mechanisms. In this paper, the estimation of the costs and benefits generated from the building of the new Cispadana regional motorway (Emilia-Romagna Region, Italy is described. The study focuses on the price variations of the industrial buildings property values in the real estate market after the new motorway will be built, aiming at developing a forecasting method, which could be repeatable and applicable to other kinds of externalities. Thanks to the hedonic pricing method, which is recurring in transport literature, using a multiple linear regression model based on ordinary least squares method (OLS, the contribution of the accessibility on the industrial buildings' pricing has been isolated; it was then possible to forecast the rise in the industrial buildings prices that will be due to the accessibility variation produced by the new infrastructure. The purpose of such a procedure is the setup of equalization mechanisms, which can re-balance the territorial effects though he so-called “land value capture” tools. Thanks to a relatively quick phase of development and implementation, the  described application could be used as a tool for the ex-ante evaluation of different infrastructure projects and as an ex-post analysis tool for the monitoring of an existing infrastructure. Finally, thanks to the chance to understand the contribution of each territorial feature to the final price of the good, this application could be very useful in participatory planning processes because it could provide a common knowledge base which could be used to support the public administration’s capability of negotiation with the private partner, both in the  participatory planning processes and in the public-private partnership

  4. Impact of MAC Delay on AUV Localization: Underwater Localization Based on Hyperbolic Frequency Modulation Signal.

    Science.gov (United States)

    Kim, Sungryul; Yoo, Younghwan

    2018-01-26

    Medium Access Control (MAC) delay which occurs between the anchor node's transmissions is one of the error sources in underwater localization. In particular, in AUV localization, the MAC delay significantly degrades the ranging accuracy. The Cramer-Rao Low Bound (CRLB) definition theoretically proves that the MAC delay significantly degrades the localization performance. This paper proposes underwater localization combined with multiple access technology to decouple the localization performance from the MAC delay. Towards this goal, we adopt hyperbolic frequency modulation (HFM) signal that provides multiplexing based on its good property, high-temporal correlation. Owing to the multiplexing ability of the HFM signal, the anchor nodes can transmit packets without MAC delay, i.e., simultaneous transmission is possible. In addition, the simulation results show that the simultaneous transmission is not an optional communication scheme, but essential for the localization of mobile object in underwater.

    Full Text Available Planning of land use by land - is an integral part of the management of land use, which provides a mechanism by which decisions are coordinated among various local, regional and national authorities, and helps implement social responsibilities of public authorities in the use and protection of land and other natural resources. Today, during the implementation of the decentralization of power, much attention is given to the transition from the existing centralized approach to conventional land-use planning (conventional land use planning, which the world is seen more as a institutional approach (institutional approach to the agreed land use planning (rarticipatory land use planning, which puts the interests of the foundation rights of economic, environmental, technological and socio-cultural conditions. Accordingly, it is important to define the relationship between the components of local governance in land development and local communities to identify the main stages of its planning, which will allow to solve social and economic problems of land use while preserving the natural ecological sustainability of land and other natural resources like land development and land use planning. It is also associated with a change in the land system ofUkraineand the transition to market land relations, which requires the transition to a new system of land use and proper planning it with the realities of today.

    To investigate the value of ultrasound-guided tattooing localization (US-tattoo) using a charcoal suspension for breast lesions. One hundred sixty-four nonpalpable breast lesions in 134 patients (mean age 47 years; range 30 74 years) were marked with a charcoal suspension under US guidance. The medical records associated with the US-tattoo, the pathology results and the follow-up US results were reviewed. The average size of the localized lesions was 1.0 cm. The procedure time was < 5 minutes (range, 2 10 minutes) per lesion. The US-tattoo was well tolerated in all cases. The only technical difficulty encountered was a needle tip blockage caused by a large charcoal particle (4.9%). The surgeon easily identified the tattoo with the exception one case. In addition, surgery could be safely delayed from one to 57 days after the making US-tattoo. The pathology result was benign in 108 cases, borderline in five, and malignant in 51. The excised specimen was < 4 cm in 76.6% (82/107) of the benign cases (mean; 2.7 cm). The pathologist could identify the mass around the tattoo and was able to make a specific diagnosis in 81.3% (87/107) of benign lesions. The only complication encountered was residual charcoal marking along the incision scar (3.6%). All follow- up US documented the removal of the lesions. An US-tattoo for nonpalpable breast lesions is a very simple and accurate method that can help surgeons design and schedule an open biopsy.

    A neutrino-oscillation analysis is performed of the more finely binned Super-Kamiokande (Super-K) atmospheric, MINOS, and CHOOZ data to examine the effect of neutrino hierarchy in this data set on the value of θ 13 and the deviation of θ 23 from maximal mixing. Exact oscillation probabilities are used, thus incorporating all powers of θ 13 and ε:=θ 23 -π/4. The extracted oscillation parameters are found to be dependent on the hierarchy, particularly for θ 13 . We find, at a 90% confidence level, that these parameters are Δ 32 =2.44 -0.20 +0.26 and 2.48 -0.22 +0.25 x10 -3 eV 2 , ε=θ 23 -π/4=0.06 -0.16 +0.06 and 0.06 -0.17 +0.08 , and θ 13 =-0.07 -0.11 +0.18 and -0.13 -0.16 +0.23 , for the normal and inverted hierarchies, respectively. The inverted hierarchy is preferred at a statistically insignificant level of 0.3σ.

    2013-01-01

    We consider narrow band, active array imaging of localized scatterers in a homogeneous medium with and without additive noise. We consider both single and multiple illuminations and study ℓ 1 minimization-based imaging methods. We show that for large arrays, with array diameter comparable to range, and when scatterers are sparse and well separated, ℓ 1 minimization using a single illumination and without additive noise can recover the location and reflectivity of the scatterers exactly. For multiple illuminations, we introduce a hybrid method which combines the singular value decomposition and ℓ 1 minimization. This method can be used when the essential singular vectors of the array response matrix are available. We show that with this hybrid method we can recover the location and reflectivity of the scatterers exactly when there is no noise in the data. Numerical simulations indicate that the hybrid method is, in addition, robust to noise in the data. We also compare the ℓ 1 minimization-based methods with others including Kirchhoff migration, ℓ 2 minimization and multiple signal classification. (paper)

    Tollaksen, Jeff

    2014-04-01

    In this article, we will examine new fundamental aspects of "emergence" and "information" using novel approaches to quantum mechanics which originated from the group around Aharonov. The two-state vector formalism provides a complete description of pre- and post-selected quantum systems and has uncovered a host of new quantum phenomena which were previously hidden. The most important feature is that any weak coupling to a pre- and post-selected system is effectively a coupling to a "weak value" which is given by a simple expression depending on the two-state vector. In particular, weak values, are the outcomes of so called "weak measurements" which have recently become a very powerful tool for ultra-sensitive measurements. Using weak values, we will show how to separate a particle from its properties, not unlike the Cheshire cat story: "Well! I've often seen a cat without a grin," thought Alice; "but a grin without a cat! It's the most curious thing I ever saw in all my life!" Next, we address the question whether the physics on different scales "emerges" from quantum mechanics or whether the laws of physics at those scales are fundamental. We show that the classical limit of quantum mechanics is a far more complicated issue; it is in fact dramatically more involved and it requires a complete revision of all our intuitions. The revised intuitions can then serve as a guide to finding novel quantum effects. Next we show that novel experimental aspects of contextuality can be demonstrated with weak measurements and these suggest new restrictions on hidden variable approaches. Next we emphasize that the most important implication of the Aharonov-Bohm effect is the existence of non-local interactions which do not violate causality. Finally, we review some generalizations of quantum mechanics and their implications for "emergence" and "information." First, we review an alternative approach to quantum evolution in which each moment of time is viewed as a new "universe

Next we emphasize that the most important implication of the Aharonov-Bohm effect is the existence of non-local interactions which do not violate causality. Finally, we review some generalizations of quantum mechanics and their implications for 'emergence' and 'information'. First, we review an

    We use the Wide Field Camera 3 (WFC3) on the Hubble Space Telescope (HST) to reduce the uncertainty in the local value of the Hubble constant from 3.3% to 2.4%. The bulk of this improvement comes from new near-infrared (NIR) observations of Cepheid variables in 11 host galaxies of recent type Ia supernovae (SNe Ia), more than doubling the sample of reliable SNe Ia having a Cepheid-calibrated distance to a total of 19; these in turn leverage the magnitude-redshift relation based on ∼300 SNe Ia at z < 0.15. All 19 hosts as well as the megamaser system NGC 4258 have been observed with WFC3 in the optical and NIR, thus nullifying cross-instrument zeropoint errors in the relative distance estimates from Cepheids. Other noteworthy improvements include a 33% reduction in the systematic uncertainty in the maser distance to NGC 4258, a larger sample of Cepheids in the Large Magellanic Cloud (LMC), a more robust distance to the LMC based on late-type detached eclipsing binaries (DEBs), HST observations of Cepheids in M31, and new HST -based trigonometric parallaxes for Milky Way (MW) Cepheids. We consider four geometric distance calibrations of Cepheids: (i) megamasers in NGC 4258, (ii) 8 DEBs in the LMC, (iii) 15 MW Cepheids with parallaxes measured with HST /FGS, HST /WFC3 spatial scanning and/or Hipparcos , and (iv) 2 DEBs in M31. The Hubble constant from each is 72.25 ± 2.51, 72.04 ± 2.67, 76.18 ± 2.37, and 74.50 ± 3.27 km s{sup 1} Mpc{sup 1}, respectively. Our best estimate of H {sub 0} = 73.24 ± 1.74 km s{sup 1} Mpc{sup 1} combines the anchors NGC 4258, MW, and LMC, yielding a 2.4% determination (all quoted uncertainties include fully propagated statistical and systematic components). This value is 3.4 σ higher than 66.93 ± 0.62 km s{sup 1} Mpc{sup 1} predicted by ΛCDM with 3 neutrino flavors having a mass of 0.06 eV and the new Planck data, but the discrepancy reduces to 2.1 σ relative to the prediction of 69.3 ± 0.7 km s{sup 1} Mpc{sup 1} based on the

    The outcome of localized Ewing's sarcoma has improved with multi-disciplinary approach. Survivals of Ewing's sarcoma from the Asian countries differed between centers. We retrospectively analyzed the records of newly diagnosed localized Ewing's sarcoma patients from 2002 to 2012. The patients were analyzed in three groups; Group 1(2002-2004) who received non-ifosfomide based regimens, Group 2(2005-2008) who received VDC/IE for 12 cycles, and Group 3(2009-2012), who received VDC/IE for 17 cycles. The groups were compared for their baseline characteristics, treatment protocol and outcome. Seventy three patients were included in the study. The median age of presentation was 15 years, with slight male predominance. Axial primary was seen in 62%. The median RFS of the three groups was 26.4, 31.4 and 36.8 months respectively ( P = 0.0018). The median OS was 27.9, 35 and 43 months respectively ( P = 0.0007). At a median follow-up of 35 months, the 3 year RFS and OS for the three treatment groups were 17%, 31%, 60% and 35%, 45% and 70% respectively. Larger tumor size, axial primary, high LDH were associated with poorer survival. Radiotherapy was associated with inferior local control and survival. We found that the survival of our ESFT patients improved over time with intensified multiagent chemotherapy and with lesser time to local therapy. But the results were still inferior to those reported in literature. We had majority of patients presenting in axial site and radiotherapy as the predominant mode of local control. The outcome may further improve with surgery as local control procedure.

    A Value/Impact assessment for several alternative decay heat removal systems has been carried out using several measures. The assessment is based on an extension of the methodology presented in the Value/Impact Handbook and includes the effects of uncertainty. The assessment was carried out as a function of site population density, existing plant features, and new plant features. Value/Impact measures based on population dose are shown to be sensitive to site, while measures which monetize and aggregate risk are less so. The latter are dominated by on-site costs such as replacement power costs. (orig.)

    A significant correlation has been found between p53 mutation and response to chemotherapy or radiotherapy. To determine the prognostic value of p53 mutation in patients with locally advanced esophageal carcinoma treated with definitive chemoradiotherapy, p53 mutation was analyzed using the biopsied specimens taken for diagnosis. Concurrent chemoradiotherapy was performed for 40 patients with severe dysphagia caused by esophageal squamous cell carcinoma associated with T3 or T4 disease. Chemotherapy consisted of protracted infusion of 5-fluorouracil, combined with an infusion of cisplatinum. Radiation treatment of the mediastinum was administered concomitantly with chemotherapy. The p53 gene mutation was detected by fluorescence-based polymerase chain reaction single-strand conformation polymorphism (PCR-SSCP) methods. DNA sequences were determined for DNA fragments with shifted peaks by SSCP methods. Of the 40 patients, 15 had T3 disease and 25 had T4 disease; 11 patients had M1 lymph node (LYM) disease. Of the 40 patients, 13 (33%) achieved a complete response. The median survival time was 14 months, and the 2-year survival rate was 20%. Among the 40 tumor samples, p53 mutation was detected in 24 tumors (60%). The survival rate in the 24 patients with p53 mutation did not differ significantly from that in the 16 patients without p53 mutation. In contrast, the 15 patients with T3 disease survived longer than the 25 patients with T4 disease (P=0.016); however, the survival rate in the 11 patients with M1 LYM disease did not differ significantly from that in the 29 patients without M1 LYM disease. Concurrent chemoradiotherapy is potentially curative for locally advanced esophageal carcinoma, but p53 genetic abnormality has no impact on prognosis. (author)

    Although a randomized controlled trial for locally advanced pancreatic cancer (PC) has demonstrated a survival advantage for treatment with gemcitabine alone, chemoradiotherapy remains the treatment of choice for locally advanced disease in Japan. The aim of this study was to compare the survival benefits associated with gemcitabine and concurrent chemoradiotherapy in locally advanced unresectable PC. Seventy-seven patients with locally advanced unresectable PC were retrospectively enrolled from April 2001 to December 2006. All cases were histologically proven, and patients received gemcitabine chemotherapy (n=30) or concurrent chemoradiotherapy (based on 5-fluorouracil, n=28, or gemcitabine, n=19, as a radiosensitizer) at Aichi Cancer Center Hospital. Patients who received chemoradiotherapy had significantly better performance status than those who had chemotherapy. Tumor response was 0% for chemotherapy and 13% chemoradiotherapy, but survival benefit was similar among patients in the chemotherapy group (overall response (OS) 12 months; progression-free survival (PFS), 3 months) and those in the chemoradiotherapy group (OS, 13 months; PFS, 5 months). Two-year survival was 21% for chemotherapy patients and 19% for chemoradiotherapy patients. Severe toxicities (Grade 3-4 National Cancer Institute-Common Toxicity Criteria, version 3.0) were significantly more frequent for chemoradiotherapy than for chemotherapy. Gemcitabine chemotherapy showed similar survival benefit compared to 5-fluorouracil- and gemcitabine-based chemoradiotherapy. (author)

    The local injurious effects of traffic appear mostly in densely populated areas, where the demand for transport is high. The local environmental effects of transportation can be reduced by measures of urban planning, traffic planning, vehicle technology and economical restrictions. Land use planning, concentration of urban structure and promoting distance working are examples of expedients of urban planning. The methods of urban planning usually affect very slowly on transport structure, but they also have a significant and continuous influence on travel demand. The methods of traffic planning generally tend to increase the fluency of traffic flow or reduce private car traffic with diverse restrictions by supporting environmentally more favourable vehicles or modes of travel. The improvements in vehicle technology can be significant in the short run. By economical regulations it is possible to guide the demand for traffic to a desirable direction. The local injurious effects of traffic vary by the size of urban areas. Local conditions, such as urban structure, population density, structure of employment, and composition of transport structure, influence on travel pattern and modal split. In Tampere University of Technology several measures to reduce environmental effects and energy consumption of transportation has been evaluated. This article presents three types of categories. As technological measures the introduction of electric vehicles and the alternative bus fuels have been studied. In addition, the effects of introducing midibuses, the car pool system and the increasing of vehicle occupancy have been evaluated as measures, which generally increase transportation system efficiency.

    Purpose: There are no simple guidelines on when to perform multidetector-row computed tomography (MDCT) for diagnosis of obscure acute gastrointestinal bleeding (AGIB). We used a risk scoring system to evaluate the diagnostic power of MDCT for patients with obscure AGIB. Materials and methods: Ninety-two patients with obscure AGIB who were referred for an MDCT scan after unsuccessful endoscopic treatment at presentation were studied. We recorded clinical data and calculated Blatchford score for each patient. Patients who required transfusion more than 500 mL of blood to maintain the vital signs were classified as high-risk patients. Two radiologists independently reviewed and categorized MDCT signs of obscure AGIB. Discordant findings were resolved by consensus. One-way ANOVA was used to compare clinical data between two groups; kappa statistics were used to estimate agreement on MDCT findings between radiologists. Results: Of the 92 patients, 62 (67.4%) were classified as high-risk patients. Blatchford scores of high-risk patients were significantly greater than those of low-risk patients. Sensitivity for MDCT diagnosing obscure AGIB was 81% in high-risk patients, as compared with 50% in the low-risk. When used in conjunction with selection of the cut-off value of 13 in Blatchford scoring system, the sensitivity and specificity of MDCT were 70.9% and 73.7%, respectively. Contrast extravasation was the most specific sign of AGIB (k = .87), recognition of which would have improved diagnostic accuracy. Conclusions: With the aid of Blatchford scoring system for evaluating the disease severity, MDCT can localize the bleeders of obscure AGIB more efficiently.

    In this paper, we study the problem of protecting privacy in the publication of set-valued data. Consider a collection of supermarket transactions that contains detailed information about items bought together by individuals. Even after removing all personal characteristics of the buyer, which can serve as links to his identity, the publication of such data is still subject to privacy attacks from adversaries who have partial knowledge about the set. Unlike most previous works, we do not distinguish data as sensitive and non-sensitive, but we consider them both as potential quasi-identifiers and potential sensitive data, depending on the knowledge of the adversary. We define a new version of the k-anonymity guarantee, the k m-anonymity, to limit the effects of the data dimensionality, and we propose efficient algorithms to transform the database. Our anonymization model relies on generalization instead of suppression, which is the most common practice in related works on such data. We develop an algorithm that finds the optimal solution, however, at a high cost that makes it inapplicable for large, realistic problems. Then, we propose a greedy heuristic, which performs generalizations in an Apriori, level-wise fashion. The heuristic scales much better and in most of the cases finds a solution close to the optimal. Finally, we investigate the application of techniques that partition the database and perform anonymization locally, aiming at the reduction of the memory consumption and further scalability. A thorough experimental evaluation with real datasets shows that a vertical partitioning approach achieves excellent results in practice. © 2010 Springer-Verlag.

    Structural damage induced by an aircraft crashing into a reinforced concrete structure includes local damage caused by the deformable engines, and global damage caused by the entire aircraft. Local damage to the target may consist of spalling of concrete from its front face together with missile penetration into it, scabbing of concrete from its rear face, and perforation of missile through it. Until now, local damage to concrete structures has been mainly evaluated by rigid missile impact tests. Past research work regarding local damage caused by impact of deformable missiles has been limited. This paper presents the results of a series of impact tests of small-, intermediate-, and full-scale engine models into reinforced concrete panels. The purpose of the tests was to determine the local damage to a reinforced concrete structure caused by the impact of a deformable aircraft engine. (orig.)

  14. Approach to assessing local socio-cultural impacts using projections of population growth and composition

    Baldwin, T. E.; Poetsch, R.

    1977-08-01

    All assessment of future domestic development projects assumes that the problems to be examined have been properly identified and defined before the application of a projection technique. An attempt is made to codify socio-cultural problems mentioned in literature and clarify how existing demographic projection techniques can be applied to assessing the problems. The relationship between changes in local population size and composition induced by in-migration and the potential for socio-cultural incompatibilities is described heuristically. For simplification, the problems expected to emerge from differences in demographic composition are classified into three categories: (1) service needs, such as those for housing, recreation, and education; (2) types of social organizations related to capacities for, or constraints on, reaping the benefits of rapid economic development and social changes (e.g., employment and income); and (3) attitudes, values, and cultural perspectives. These areas of concern are very broad, and quantitative projections of population size and composition are more easily related to the first than to the third. Although demographic projection provides a valuable tool for estimating future social change, the knowledge about cause and effect is not sufficient to support the quantification of socio-cultural impact. Therefore, the projections are used only as relative indicators and the assessments of socio-cultural impact based on them are qualitative only. Therefore, identification and assessment of socio-cultural impacts are a means of developing plans to overcome the expected problems.

    The modern biodiversity crisis reflects global extinctions and local introductions. Human activities have dramatically altered rates and scales of processes that regulate biodiversity at local scales. Reconciling the threat of global biodiversity loss with recent evidence of stability at fine spatial scales is a major challenge and requires a nuanced approach to biodiversity change that integrates ecological understanding. With a new dataset of 471 diversity time series spanning from 1962 to 2015 from marine coastal ecosystems, we tested (1) whether biodiversity changed at local scales in recent decades, and (2) whether we can ignore ecological context (e.g., proximate human impacts, trophic level, spatial scale) and still make informative inferences regarding local change. We detected a predominant signal of increasing species richness in coastal systems since 1962 in our dataset, though net species loss was associated with localized effects of anthropogenic impacts. Our geographically extensive dataset is unlikely to be a random sample of marine coastal habitats; impacted sites (3% of our time series) were underrepresented relative to their global presence. These local-scale patterns do not contradict the prospect of accelerating global extinctions but are consistent with local species loss in areas with direct human impacts and increases in diversity due to invasions and range expansions in lower impact areas. Attempts to detect and understand local biodiversity trends are incomplete without information on local human activities and ecological context. Copyright © 2015 Elsevier Ltd. All rights reserved.

    By measuring the foliar δ13C values of common local plant species grown in different soil types in Wangjiazhai catchments, a typical karst desertification area in Qingzhen City, Central Guizhou, we studied the impact of soil type and rocky desertification grade on the foliar δ13C values. The results showed that the foliar δ13C values were more negative in yellow soil area than those in black calcareous area and there was no obvious difference in foliar δ13C values between these two soil types. The distribution interval of foliar δ13C values in yellow soil area was narrower than those in black calcareous area and the variation coefficient of foliar δ13C values in yellow soil area were smaller than those in black calcareous area. With increasing degree of karst rocky desertification, the foliar δ13C values of plant community in black calcareous area increased, whereas those in yellow soil area first increased and then decreased. The result of multiple comparison showed that the difference in foliar δ13C values of plant community among rocky desertification grade was not obvious in yellow soil area, but it was obvious in black calcareous area. Correlation analysis between the foliar δ13C values of plant species and the main environmental factors indicated that slope and soil thickness were the main factors which affected the foliar δ13C values of plants in yellow soil area and soil water contant was the main factor in black calcareous area. The impact of soil on the foliar δ13C values was realized by adjusting the soil moisture in study area.

    Local sensitivity analysis provides computationally frugal ways to evaluate models commonly used for resource management, risk assessment, and so on. This includes diagnosing inverse model convergence problems caused by parameter insensitivity and(or) parameter interdependence (correlation), understanding what aspects of the model and data contribute to measures of uncertainty, and identifying new data likely to reduce model uncertainty. Here, we consider sensitivity statistics relevant to models in which the process model parameters are transformed using singular value decomposition (SVD) to create SVD parameters for model calibration. The statistics considered include the PEST identifiability statistic, and combined use of the process-model parameter statistics composite scaled sensitivities and parameter correlation coefficients (CSS and PCC). The statistics are complimentary in that the identifiability statistic integrates the effects of parameter sensitivity and interdependence, while CSS and PCC provide individual measures of sensitivity and interdependence. PCC quantifies correlations between pairs or larger sets of parameters; when a set of parameters is intercorrelated, the absolute value of PCC is close to 1.00 for all pairs in the set. The number of singular vectors to include in the calculation of the identifiability statistic is somewhat subjective and influences the statistic. To demonstrate the statistics, we use the USDA’s Root Zone Water Quality Model to simulate nitrogen fate and transport in the unsaturated zone of the Merced River Basin, CA. There are 16 log-transformed process-model parameters, including water content at field capacity (WFC) and bulk density (BD) for each of five soil layers. Calibration data consisted of 1,670 observations comprising soil moisture, soil water tension, aqueous nitrate and bromide concentrations, soil nitrate concentration, and organic matter content. All 16 of the SVD parameters could be estimated by

    International regulations for nuclear power plants strictly prescribe the design requirements for local impact loads, such as aircraft engine impact, and internal and external missile impact. However, the local impact characteristics of Steel-plate Concrete (SC) walls are not easy to evaluate precisely because the dynamic impact behavior of SC walls which include external steel plate, internal concrete, tie-bars, and studs, is so complex. In this study, dynamic impact characteristics of SC walls subjected to local missile impact load are investigated via actual high-speed impact test and numerical simulation. Three velocity checkout tests and four SC wall tests were performed at the Energetic Materials Research and Testing Center (EMRTC) site in the USA. Initial and residual velocity of the missile, strain and acceleration of the back plate, local failure mode (penetration, bulging, splitting and perforation) and deformation size, etc. were measured to study the local behavior of the specimen using high speed cameras and various other instrumentation devices. In addition, a more advanced and applicable numerical simulation method using the finite element (FE) method is proposed and verified by the experimental results. Finally, the experimental results are compared with the local failure evaluation formula for SC walls recently proposed, and future research directions for the development of a refined design method for SC walls are reviewed.

  19. Ethical precepts for medical volunteerism: including local voices and values to guide RHD surgery in Rwanda.

    Coors, Marilyn E; Matthew, Thomas L; Matthew, Dayna B

    2015-10-01

    At the invitation of the Rwandan Government, Team Heart, a team of American healthcare professionals, performs volunteer rheumatic heart disease (RHD) surgery in Rwanda every year, and confronts ethical concerns that call for cultural sensitivity. This article describes how five standard bioethical precepts are applied in practice in medical volunteerism related to RHD surgery in Rwanda. The content for the applied precepts stems from semiscripted, transcribed conversations with the authors, two Rwandan cardiologists, a Rwandan nurse and a Rwandan premedical student. The conversations revealed that the criteria for RHD surgical selection in Rwanda are analogous to the patient-selection process involving material scarcity in the USA. Rwandan notions of benefit and harm focus more attention on structural issues, such as shared benefit, national reputation and expansion of expertise, than traditional Western notions. Harm caused by inadequate patient follow-up remains a critical concern. Gender disparities regarding biological and social implications of surgical valve choices impact considerations of justice. Individual agency remains important, but not central to Rwandan concepts of justice, transparency and respect, particularly regarding women. The Rwandan understanding of standard bioethical precepts is substantively similar to the traditionally recognised interpretation with important contextual differences. The communal importance of improving the health of a small number of individuals may be underestimated in previous literature. Moreover, openness and the incorporation of Rwandan stakeholders in difficult ethical choices and long-term contributions to indigenous medical capacity appear to be valued by Rwandans. These descriptions of applied precepts are applicable to different medical missions in other emerging nations following a similar process of inclusion. Published by the BMJ Publishing Group Limited.

  4. The local dark matter phase-space density and impact on WIMP direct detection

    2012-01-01

    We present a new determination of the local dark matter phase-space density. This result is obtained implementing, in the limit of isotropic velocity distribution and spherical symmetry, Eddington's inversion formula, which links univocally the dark matter distribution function to the density profile, and applying, within a Bayesian framework, a Markov Chain Monte Carlo algorithm to sample mass models for the Milky Way against a broad and variegated sample of dynamical constraints. We consider three possible choices for the dark matter density profile, namely the Einasto, NFW and Burkert profiles, finding that the velocity dispersion, which characterizes the width in the distribution, tends to be larger for the Burkert case, while the escape velocity depends very weakly on the profile, with the mean value we obtain being in very good agreement with estimates from stellar kinematics. The derived dark matter phase-space densities differ significantly — most dramatically in the high velocity tails — from the model usually taken as a reference in dark matter detection studies, a Maxwell-Boltzmann distribution with velocity dispersion fixed in terms of the local circular velocity and with a sharp truncation at a given value of the escape velocity. We discuss the impact of astrophysical uncertainties on dark matter scattering rates and direct detection exclusion limits, considering a few sample cases and showing that the most sensitive ones are those for light dark matter particles and for particles scattering inelastically. As a general trend, regardless of the assumed profile, when adopting a self-consistent phase-space density, we find that rates are larger, and hence exclusion limits stronger, than with the standard Maxwell-Boltzmann approximation. Tools for applying our result on the local dark matter phase-space density to other dark matter candidates or experimental setups are provided

  7. Local Impact Simulation of SC Wall Structures using Aircraft Engine Projectile

    SC wall structure developed for nuclear power plant buildings consists of plain concrete and two steel plates on both surface of the concrete, while RC structure consists of re bar and concrete. SC structure has higher scabbing resistance than RC structure due to the action of steel plate on the rear side of impact. Therefore SC structure is known as more effective structure from the viewpoint of aircraft crash than RC structure. However, most of the recent researches and experiments about local impact damage deal with RC structures, and the effect of re bar and steel plate is not considered reasonably. Although Walter et al. and Make-work et al. suggested a formula for evaluating perforation depth of steel plate covered RC walls, most of the previous researches about SC structure are focused on perforation and scabbing due to the impact of hard projectile, rather than soft projectile such as an aircraft. In this research a soft projectile, i. e. aircraft engine, is utilized for impact simulation of RC and SC walls. To evaluate local damage of SC wall structures, parametric study with the variables of wall thickness and steel ratio of the cover plate is performed, and the results are compared with those of RC structures. Since scabbing was prevented by the steel plates, penetration mode of damage was observed in SC walls while scabbing damage was occurred in RC walls. It is confirmed that the rear steel plate not only contains concrete debris, but also reduces the internal damage of the concrete walls. Penetration depth of SC walls did not largely vary due to the increasing steel ratio, and similar results to RC walls were observed when the wall thickness is larger than a certain value since the impact resistance of SC wall is mainly governed by the thickness of concrete part. Therefore, it is expected that similar level of impact resistance to RC structure can be produced with the minimum thickness of steel plates of SC structure. According to these results, SC

    Three sets of impact tests, small-, intermediate-, and full-scale tests, have been executed to determine local damage to reinforced concrete structures caused by the impact of aircraft engine missiles. The results of the test program showed that (1) the use of the similarity law is appropriate, (2) suitable empirical formulas exist for predicting the local damage caused by rigid missiles, (3) reduction factors may be used for evaluating the reduction in local damage due to the deformability of the engines, (4) the reinforcement ratio has no effect on local damage, and (5) the test results could be adequately predicted using nonlinear response analysis.

    Objective: To investigate the normal CT manifestation of the vascular arch of the gastric lesser curvature, and to further probe the value of CT in the localization diagnosis of the primary and stomach-originated masses in the lesser sac. Methods: Contrast-enhanced CT scanning was performed in 51 normal individuals. Emphasis of image observation was focused on the CT manifestations of vascular arch of the gastric lesser curvature and the relation between the vascular arch and the gastric wall. Also contrast- enhanced CT scan was performed for seventeen cases of primary and stomach-originated masses in the lesser sac subsequently proved by surgery and pathology. Image analysis was focused on the relation between the mass and the vascular arch and its branches of the gastric lesser curvature, the shape of the mass, and the relation between the mass and the gastric wall. Results: The vascular arch of the gastric lesser curvature was clearly visualized in the fifty normal individuals. The tributaries of the vascular arch near the cardiac part, gastric corpus, and pyloric part were revealed in 42, 10 and 7 cases respectively. The vascular arch was in close contact with the gastric wall in 38 cases. Among the 17 patients, 13 cases demonstrated the obliteration of the transparent fat plane between the mass and the gastric wall. In 6 patients with stomach- originated masses, 5 patients showed the stretching of vascular arch tributaries adjacent to the masses, and no vascular arch and its tributaries could be not visualized between the masses and the stomach. In 11 patients with primary masses in the lesser sac, vascular arch were showed between the masses and the stomach in 10 cases, and no stretching of vascular arch tributaries adjacent to the masses could be showed. Conclusions: CT scan can clearly depict the normal vascular arch and its branches of the gastric lesser curvature. Based on the relation between the vascular arch and the gastric wall, the presence of fat

    In this work the local values of contact potential difference (CPD) and their distributions in the plane of the metal-insulator-semiconductor (MIS) structure's gate have been determined for the first time. This has been achieved by application of a focused beam of UV radiation from a laser source. The less than 20-{mu}m diameter of UV radiation beam allows determination of distributions of local CPD values in the plane of the gate. The CPD distribution is such that its values are highest far away from the gate edge regions, lower in the vicinity of gate edges and still lower in the vicinity of gate corners. In this paper the method and the optical setup used to determine local values of CPD are described and example measurement results are given. The CPD distributions obtained have been confirmed by a series of independent measurements by other methods. It is believed that the CPD distributions obtained (as well as distributions of local values of other parameters) are due to the mechanical stress distributions under the gate of a MIS system.

    2017-06-01

    Full Text Available The purpose of this paper is to examine residents’ perceptions of the socio-cultural impacts of tourism in Mangochi, Malawi. This paper is based on results of a survey of 196 households together with ten key informant interviews. A concurrent triangulation mixed method was used to ensure well-validated and substantiated findings. The study findings indicate that local residents perceive specific positive and negative socio-cultural impacts of tourism in their community. Some of the positive sociocultural impacts of tourism include the provision of jobs; improved personal incomes; stimulation of the local economy and improved security in the destination area. However, the study also revealed two major negative socio-cultural impacts of tourism: the migration of people to the area in search of jobs; and the influence of Western visitors on local culture and “the way of life” of local people due to the demonstration effect. The paper indicates the degree to which local residents perceive different socio-cultural impacts of tourism development in an African local community setting. Therefore, the paper will assist tourism planners and local government in the planning and implementation of tourism development strategies for the area aiming at consolidating local residents’ support for tourism.

  15. Human Impacts on the Hydrologic Cycle: Comparing Global Climate Change and Local Water Management

    Science.gov (United States)

    Ferguson, I. M.; Maxwell, R. M.

    2010-12-01

    Anthropogenic climate change is significantly altering the hydrologic cycle at global and regional scales, with potentially devastating impacts on water resources. Recent studies demonstrate that hydrologic response to climate change will depend on local-scale feedbacks between groundwater, surface water, and land surface processes. These studies suggest that local water management practices that alter the quantity and distribution of water in the terrestrial system—e.g., groundwater pumping and irrigation—may also feed back across the hydrologic cycle, with impacts on land-atmosphere fluxes and thus weather and climate. Here we use an integrated hydrologic model to compare the impacts of large-scale climate change and local water management practices on water and energy budgets at local and watershed scales. We consider three climate scenarios (hot, hot+wet, and hot+dry) and three management scenarios (pumping only, irrigation only, and pumping+irrigation). Results demonstrate that impacts of local water management on basin-integrated groundwater storage, evapotranspiration, and stream discharge are comparable to those of changing climate conditions. However, impacts of climate change are shown to have a smaller magnitude and greater spatial extent, while impacts of pumping and irrigation are shown to have a greater magnitude but are local to areas where pumping and irrigation occur. These results have important implications regarding the scales of human impacts on both water resources and climate and the sustainability of water resources.

    Objective To examine the association between bodyweight status and provision of population-based prevention services. Data Sources The National Association of City and County Health Officials 2005 Profile survey data, linked with two cross-sections of the Behavioral Risk Factor Surveillance System (BRFSS) survey in 2004 and 2005. Study Design Multilevel logistic regressions were used to examine the association between provision of obesity-prevention services and the change in risk of being obese or morbidly obese among BRFSS respondents. The estimation sample was stratified by sex. Low-income samples were also examined. Falsification tests were used to determine whether there is counterevidence. Principal Findings Provision of population-based obesity-prevention services within the jurisdiction of local health departments and specifically those provided by the local health departments are associated with reduced risks of obesity and morbid obesity from 2004 to 2005. The magnitude of the association appears to be stronger among low-income populations and among women. Results of the falsification tests provide additional support of the main findings. Conclusions Population-based obesity-prevention services may be useful in containing the obesity epidemic. PMID:22816510

  18. Digital Sequences and a Time Reversal-Based Impact Region Imaging and Localization Method

    2013-01-01

    To reduce time and cost of damage inspection, on-line impact monitoring of aircraft composite structures is needed. A digital monitor based on an array of piezoelectric transducers (PZTs) is developed to record the impact region of impacts on-line. It is small in size, lightweight and has low power consumption, but there are two problems with the impact alarm region localization method of the digital monitor at the current stage. The first one is that the accuracy rate of the impact alarm region localization is low, especially on complex composite structures. The second problem is that the area of impact alarm region is large when a large scale structure is monitored and the number of PZTs is limited which increases the time and cost of damage inspections. To solve the two problems, an impact alarm region imaging and localization method based on digital sequences and time reversal is proposed. In this method, the frequency band of impact response signals is estimated based on the digital sequences first. Then, characteristic signals of impact response signals are constructed by sinusoidal modulation signals. Finally, the phase synthesis time reversal impact imaging method is adopted to obtain the impact region image. Depending on the image, an error ellipse is generated to give out the final impact alarm region. A validation experiment is implemented on a complex composite wing box of a real aircraft. The validation results show that the accuracy rate of impact alarm region localization is approximately 100%. The area of impact alarm region can be reduced and the number of PZTs needed to cover the same impact monitoring region is reduced by more than a half. PMID:24084123

    2017-01-01

    For addressing potential food shortages, a fundamental tradeoff exists between investing more resources to increasing productivity of existing crops, as opposed to increasing crop diversity by incorporating more species. We explore ways to use local plants as food resources and the potential to promote food diversity and agricultural resilience. We discuss how use of local plants and the practice of local agriculture can contribute to ongoing adaptability in times of global change. Most food crops are now produced, transported, and consumed long distances from their homelands of origin. At the same time, research and practices are directed primarily at improving the productivity of a small number of existing crops that form the cornerstone of a global food economy, rather than to increasing crop diversity. The result is a loss of agro-biodiversity, leading to a food industry that is more susceptible to abiotic and biotic stressors, and more at risk of catastrophic losses. Humans cultivate only about 150 of an estimated 30,000 edible plant species worldwide, with only 30 plant species comprising the vast majority of our diets. To some extent, these practices explain the food disparity among human populations, where nearly 1 billion people suffer insufficient nutrition and 2 billion people are obese or overweight. Commercial uses of new crops and wild plants of local origin have the potential to diversify global food production and better enable local adaptation to the diverse environments humans inhabit. We discuss the advantages, obstacles, and risks of using local plants. We also describe a case study-the missed opportunity to produce pine nuts commercially in the Western United States. We discuss the potential consequences of using local pine nuts rather than importing them overseas. Finally, we provide a list of edible native plants, and synthesize the state of research concerning the potential and challenges in using them for food production. The goal of our

    Human impact on nature is increasing - not only in magnitude, but also in geographical scale. It has been known for centuries, that vegetation does not thrive near air pollution sources, but it was not before after the Second World War that the importance of long range transport of pollutants was realized - first for sulphur and nitrogen compounds, later for photochemical oxidants. The results have been acidification of rivers and lakes, forest dieback and eutrophication of inner waters. In recent decades the attention has been focused on global effects: Ozone depletion and increased greenhouse effect. Here air pollution threatens to alter the conditions of life on the entire Earth. In the political and public debate - and sometimes in science as well - the problems are treated separately. Since however, the basic phenomena all take place in the same atmosphere, they are more or less interrelated. Also the environmental effects must be considered a result of a complex impact. This complexity should be taken into account in the planning of an effective abatement strategy. (au) 11 refs

    The movie 'Into the Wilde' evoke the impression of the last frontier in a great wide and pristine land. With over half a million people living in Alaska an area as larger as the distance from the US West to the East Coast, this idea comes naturally. The three major cities are the main emission source in an otherwise relative clean atmosphere. On the North Slope oil drilling and production is the main anthropogenic emission sources. Along Alaska's coasts ship traffic including cruises is another anthropogenic emission source that is expected to increase as sea-ice recedes. In summer, wildfires in Alaska, Canada and/or Siberia may cause poor air quality. In winter inversions may lead poor air quality and in spring. In spring, aged polluted air is often advected into Alaska. These different emission sources yield quite different atmospheric composition and air quality impacts. While this may make understanding Alaska's atmospheric composition at-large a challenging task, it also provides great opportunities to examine impacts without co-founders. The talk will give a review of the performed research, and insight into the challenges.

    The Jobs and Economic Development Impacts (JEDI) models, developed by the National Renewable Energy Laboratory (NREL) for the U.S. Department of Energy (DOE) Office of Energy Efficiency and Renewable Energy (EERE), use input-output methodology to estimate gross (not net) jobs and economic impacts of building and operating selected types of renewable electricity generation and fuel plants. This analysis provides the DOE with an assessment of the value, impact, and validity of the JEDI suite of models. While the models produce estimates of jobs, earnings, and economic output, this analysis focuses only on jobs estimates. This validation report includes an introduction to JEDI models, an analysis of the value and impact of the JEDI models, and an analysis of the validity of job estimates generated by JEDI model through comparison to other modeled estimates and comparison to empirical, observed jobs data as reported or estimated for a commercial project, a state, or a region.

    Little attention has been paid to understanding the impact of values, attributes and characteristics of drugs workers on therapeutic relationships and treatment outcomes. Interaction of values with other variables is considered to be of importance since values play a role in determining attitudes and behaviours. This exploratory study investigates the impact of drug workers' personal values on client outcomes within a drug treatment service. Eight drug workers and 58 clients were recruited at a UK charity working with problematic drug users who are also socially excluded. Drug workers completed a validated questionnaire to elicit their personal values. Client outcomes were assessed using the Christo Inventory for Substance Misuse Services. The relationship between client outcomes and worker values were analysed using Spearman's rank test of association. Drug workers prioritising stimulation, self-direction and hedonism value types experienced more positive client outcomes compared with those prioritising security, conformity, benevolence, tradition and universalism types. The value types associated with positive outcomes fall within Schwartz's 'openness to change' superordinate dimension, whereas those related to more negative outcomes fall within the 'conservation' dimension. The study suggests that drug workers' personal values may have a significant impact upon client outcomes in the treatment of substance misuse. Reasons for this finding are explored, as are limitations of this study and suggestions for future research.

    Structural safety evaluation of nuclear power plant considers two distinct types of structural failure, local failure and global failure. In the local failure evaluation, considered projectiles can be divided as internal and external projectile according to the impact location, and they also can be divided as rigid and soft projectile according to the deformation level after impact. Frequently considered projectiles are aircraft engine, tornado, and turbine projectile. When the speed and weight of the projectiles are considered, the most influential projectile is aircraft engine, which is one of the soft projectiles. Sugano et al. performed impact test using an engine model projectile, which is derived from GE-J79 engine and concentrated mass-spring model idealization. Kojima and Sugano et al. demonstrated from their experiments that steel liner on the rear side of the concrete wall reduces impact induced damage and suppresses debris scattering. Chung et al. performed comparison study of various formulae suggested for local damage evaluation using previously performed numerous local impact test results. Also, they validated a methodology of numerical analysis for impact simulation using LS-DYNA. Previously suggested formulae and research results do not consider the effect of liner plate or curved shape of the containment building walls on the local damage. In this research, flat wall and curved wall are individually modeled using the same curvature of nuclear power plants, and the effects of curvature and liner plates on the local damage are analytically investigated

    Full Text Available Although in recent decades, meat from hunted wild ungulates has shown interesting results in terms of market opportunities, the scientific literature is still lacking in economic studies concerning the estimation of the meat’s value for involved stakeholders. We present an analysis of the evolution of price in the local red deer meat supply chain. This analysis has been conducted through a survey based on in-depth interviews with the stakeholders involved in an Italian local supply chain. Findings derived from this study describe a case study, however, they also represent the potential dynamics of the value of Italian game meat, highlighting that the development of a sustainable local supply chain of this product may represent an economic resource for involved stakeholders.

  14. The local enhancement conundrum: in search of the adaptive value of a social learning mechanism.

    2014-02-01

    Social learning mechanisms are widely thought to vary in their degree of complexity as well as in their prevalence in the natural world. While learning the properties of a stimulus that generalize to similar stimuli at other locations (stimulus enhancement) prima facie appears more useful to an animal than learning about a specific stimulus at a specific location (local enhancement), empirical evidence suggests that the latter is much more widespread in nature. Simulating populations engaged in a producer-scrounger game, we sought to deploy mathematical models to identify the adaptive benefits of reliance on local enhancement and/or stimulus enhancement, and the alternative conditions favoring their evolution. Surprisingly, we found that while stimulus enhancement readily evolves, local enhancement is advantageous only under highly restricted conditions: when generalization of information was made unreliable or when error in social learning was high. Our results generate a conundrum over how seemingly conflicting empirical and theoretical findings can be reconciled. Perhaps the prevalence of local enhancement in nature is due to stimulus enhancement costs independent of the learning task itself (e.g. predation risk), perhaps natural habitats are often characterized by unreliable yet highly rewarding payoffs, or perhaps local enhancement occurs less frequently, and stimulus enhancement more frequently, than widely believed.

    2015-04-01

    Improving value within critical care remains a priority because it represents a significant portion of health-care spending, faces high rates of adverse events, and inconsistently delivers evidence-based practices. ICU directors are increasingly required to understand all aspects of the value provided by their units to inform local improvement efforts and relate effectively to external parties. A clear understanding of the overall process of measuring quality and value as well as the strengths, limitations, and potential application of individual metrics is critical to supporting this charge. In this review, we provide a conceptual framework for understanding value metrics, describe an approach to developing a value measurement program, and summarize common metrics to characterize ICU value. We first summarize how ICU value can be represented as a function of outcomes and costs. We expand this equation and relate it to both the classic structure-process-outcome framework for quality assessment and the Institute of Medicine's six aims of health care. We then describe how ICU leaders can develop their own value measurement process by identifying target areas, selecting appropriate measures, acquiring the necessary data, analyzing the data, and disseminating the findings. Within this measurement process, we summarize common metrics that can be used to characterize ICU value. As health care, in general, and critical care, in particular, changes and data become more available, it is increasingly important for ICU leaders to understand how to effectively acquire, evaluate, and apply data to improve the value of care provided to patients.

    Soldiers are at increased risk of developing mental health disorders after military deployment. The impact of personal values on psychological symptomatology based on an empirical working model has not yet been studied in a military environment. 117 German Armed Forces soldiers completed the Portrait-Values-Questionnaire (PVQ), the Patient-Health-Questionnaire (PHQ) and the Resilience-Scale (RS-11) after their deployment to Afghanistan. In the regression analyses the values hedonism, benevolence, tradition, self-direction and universalism had a differential significant impact on depression, anxiety and somatoform symptoms of the PHQ. The RS-11 sum scale values were negatively correlated with symptomatology. Personal values and resilience seem to be associated with psychological symptomatology in soldiers after military deployment. The results can contribute to the further development of both preventive and therapeutic approaches. © Georg Thieme Verlag KG Stuttgart · New York.

    The local lymph node assay (LLNA) is a skin sensitization test that provides animal welfare benefits. To reduce animal usage further, a modified version (rLLNA) was proposed. Conducting the rLLNA as a screening test with a single high dose group and vehicle control differentiated accurately between skin sensitizers and non-sensitizers. This study examined whether a reduction in animal number/group is feasible. Historical data were utilized to examine the impact of conducting the rLLNA with two mice/group. To assess the effect on the stimulation index (SI) 41 datasets with individual animal data derived using five mice/group were analysed. SIs were calculated on all possible combinations of two control and two high dose group disintegrations per minute (dpm) values. For 25 of 33 sensitizer datasets, > 96% of possible dpm combinations resulted in a calculated SI > 3. The lowest percentages of positive SIs were observed with weak allergens when, in the standard LLNA, the mean SIs would have been nearer to the threshold value of 3. The results indicate that moderate, strong and extreme allergens are more likely than weak allergens to be identified as sensitizers when group sizes of two mice are used within the rLLNA. It is concluded that a rLLNA with two mice/group would display decreased sensitivity and is inappropriate for use in hazard identification. Copyright (c) 2007 John Wiley & Sons, Ltd.

    2006-09-01

    Osteoarthritis (OA) is a leading cause of disability. Numerous tools are available to assess this, but they fail to place a patient value upon disability. In rheumatoid arthritis, research has shown patients have different importance values for similar disabilities, and these individual values can be used to weight disability levels, creating a measure of personal impact. Firstly, to determine if the Health Assessment Questionnaire (HAQ) can be used as the basis for an importance value scale by assessing if it includes activities considered important by OA patients. Secondly, to determine if the weights used for the value scale should be based on population, healthcare professional or patient values. Twenty-five OA patients, 25 healthy controls and 25 healthcare professionals rated the importance of the items on the HAQ and shortened Modified HAQ (MHAQ). Prior to completing the HAQ, patients generated a list of activities that were important to them. The HAQ contained 69% of items that patients considered important. No items were consistently deemed unimportant by patients. There was low agreement within and between groups about the importance of the items on the HAQ and MHAQ. The HAQ is a suitable basis for a value scale for an OA disability impact score. Importance values for function differed for patients, healthcare professionals and the general population; therefore individual patient weightings need to be used. Further work is under way to validate a measure of the personal impact of disability in patients with lower limb OA. Copyright (c) 2006 John Wiley & Sons, Ltd.

  4. Environmental Impacts and Hotspots of Food Losses: Value Chain Analysis of Swiss Food Consumption.

    Beretta, Claudio; Stucki, Matthias; Hellweg, Stefanie

    2017-10-03

    Reducing food losses and waste is crucial to making our food system more efficient and sustainable. This is the first paper that quantifies the environmental impacts of food waste by distinguishing the various stages of the food value chain, 33 food categories that represent the whole food basket in Switzerland, and including food waste treatment. Environmental impacts are expressed in terms of climate change and biodiversity impacts due to water and land use. Climate change impacts of food waste are highest for fresh vegetables, due to the large amounts wasted, while the specific impact per kg is largest for beef. Biodiversity impacts are mainly caused by cocoa and coffee (16% of total) and by beef (12%). Food waste at the end of the food value chain (households and food services) causes almost 60% of the total climate impacts of food waste, because of the large quantities lost at this stage and the higher accumulated impacts per kg of product. The net environmental benefits from food waste treatment are only 5-10% of the impacts from production and supply of the wasted food. Thus, avoiding food waste should be a first-line priority, while optimizing the method of treatment is less relevant.

  5. Extended value-impact decision making methodology for nuclear power plant modifications

    International Nuclear Information System (INIS)

    Nelson, P.F.; Kastenberg, W.E.

    1985-01-01

    Value-impact is the term used by the Nuclear Regulatory Commission (NRC) to define what is traditionally known as cost-benefit analysis; values measure the beneficial consequences of a proposed action, impacts measure the adverse consequences, i.e. costs of the proposed action. In the regulatory framework, value-impact or cost-benefit is but one input to decision making. The present study was performed in order to illustrate how decision makers can utilize a more structured method for determining nuclear regulatory policy. In order to be useful, the method must treat all dominant factors that influence a decision; including economic, as well as societal factors such as environmental, health and safety. The method must also allow decisions to be consistent with the preferences of the decision maker as well as other interested groups. Major problems in decision making are how to incorporate non-quantifiable attributes in the method and how to reach consensus between opposing viewpoints. The Analytic Hierarchy Process (AHP) can attack these issues by making it possible to structure the decision in a way that subjective input can be included. In this paper, the AHP is developed and used to rank the value/impact ratios of alternative decay heat removal systems. It is believed that use of the AHP can decrease limitations present in a current value-impact analysis

  9. Does eating local food reduce the environmental impact of food production and enhance consumer health?

    Science.gov (United States)

    Edwards-Jones, Gareth

    2010-11-01

    The concept of local food has gained traction in the media, engaged consumers and offered farmers a new marketing tool. Positive claims about the benefits of local food are probably not harmful when made by small-scale producers at the local level; however, greater concern would arise should such claims be echoed in policy circles. This review examines the evidence base supporting claims about the environmental and health benefits of local food. The results do not offer any support for claims that local food is universally superior to non-local food in terms of its impact on the climate or the health of consumers. Indeed several examples are presented that demonstrate that local food can on occasions be inferior to non-local food. The analysis also considers the impact on greenhouse gas emissions of moving the UK towards self-sufficiency. Quantitative evidence is absent on the changes in overall emissions that would occur if the UK switched to self-sufficiency. A qualitative assessment suggests the emissions per item of food would probably be greater under a scenario of self-sufficiency than under the current food system. The review does not identify any generalisable or systematic benefits to the environment or human health that arise from the consumption of local food in preference to non-local food.

    Purpose: To analyze retrospectively the results of external beam radiotherapy for clinically localized hormone-refractory prostate cancer and investigate the clinical significance of nadir prostate-specific antigen (PSA) value within 12 months (nPSA12) as an early estimate of clinical outcomes after radiotherapy. Methods and Materials: Eighty-four patients with localized hormone-refractory prostate cancer treated with external beam radiotherapy were retrospectively reviewed. The total radiation doses ranged from 30 to 76 Gy (median, 66 Gy), and the median follow-up period for all 84 patients was 26.9 months (range, 2.7-77.3 months). Results: The 3-year actuarial overall survival, progression-free survival (PFS), and local control rates in all 84 patients after radiotherapy were 67%, 61%, and 93%, respectively. Although distant metastases and/or regional lymph node metastases developed in 34 patients (40%) after radiotherapy, local progression was observed in only 5 patients (6%). Of all 84 patients, the median nPSA12 in patients with clinical failure and in patients without clinical failure was 3.1 ng/mL and 0.5 ng/mL, respectively. When dividing patients according to low (<0.5 ng/mL) and high (≥0.5 ng/mL) nPSA12 levels, the 3-year PFS rate in patients with low nPSA12 and in those with high nPSA12 was 96% and 44%, respectively (p < 0.0001). In univariate analysis, nPSA12 and pretreatment PSA value had a significant impact on PFS, and in multivariate analysis nPSA12 alone was an independent prognostic factor for PFS after radiotherapy. Conclusions: External beam radiotherapy had an excellent local control rate for clinically localized hormone-refractory prostate cancer, and nPSA12 was predictive of clinical outcomes after radiotherapy.

    Full Text Available The impact of rough surface topography on the electric potential and electric field is generally neglected due to the small scale of surface roughness compared to the width of the plasma sheath. However, the distributions of the electric potential and field on rough surfaces are expected to influence the characteristics of edge plasma and the local impact angle. The distributions of plasma sheath and local impact angle on rough surfaces are investigated by a two dimension-in-space and three dimension-in-velocity (2d3v Particle-In-Cell (PIC code. The influences of the plasma temperature andsurface morphology on the plasma sheath, local impact angle and resulting physical sputtering yield on rough surfaces are investigated.

    Zhong, Yongteng; Xiang, Jiawei

    2017-05-01

    1-D uniform linear array (ULA) has the shortcoming of the half-plane mirror effect, which does not allow discriminating between a target placed above the array and a target placed below the array. This paper presents time difference (TD) and multiple signal classification (MUSIC) based omni-directional impact localization on a large stiffened composite structure using improved linear array, which is able to perform omni-directional 360° localization. This array contains 2M+3 PZT sensors, where 2M+1 PZT sensors are arranged as a uniform linear array, and the other two PZT sensors are placed above and below the array. Firstly, the arrival times of impact signals observed by the other two sensors are determined using the wavelet transform. Compared with each other, the direction range of impact source can be decided in general, 0°to 180° or 180°to 360°. And then, two dimensional multiple signal classification (2D-MUSIC) based spatial spectrum formula using the uniform linear array is applied for impact localization by the general direction range. When the arrival times of impact signals observed by upper PZT is equal to that of lower PZT, the direction can be located in x axis (0°or 180°). And time difference based MUSIC method is present to locate impact position. To verify the proposed approach, the proposed approach is applied to a composite structure. The localization results are in good agreement with the actual impact occurring positions.

    2018-04-01

    Full Text Available This article highlights the motivational factors behind consumers’ and tourists’ decisions to buy local artisan cheese in Jämtland (Sweden. Empirically, the case itself diverts from the typical Franco-Mediterranean case in which both the actions of producers and consumers are embedded in historical, long-term culinary traditions and territorial features, nor is it the typical farmers’ market or another market-driven direct produce system. The main purpose is to shed light on the motivational factors behind the purchasing decision of consumers and tourists by studying the attributes that consumers embody in the products. The article is based on two consumer surveys/short interviews, the first conducted in June 2012 and the second in February 2017. The results were tested against/related to the wider local food discussion conceptualized through four types of attributes. Namely, intrinsic and extrinsic attributes; post-modernity and environmental attributes; geographical and territorial attributes; and local and rural development attributes. The results in this article clearly show that consumers value a combination of different attributes from both market-driven direct produce systems and close typicity systems. Therefore, the construction of proximity from the point of view of the consumer can be derived from a complex set of attributes and motivational factors not normally highlighted in the localized food discussion.

It extends the state-of-the-art value-impact methodology by using the Analytic Hierarchy Process (AHP), a formalized decision making tool for ranking alternatives based on judgement. The AHP reduces some of the limitations present in current value-impact work, such as the inability to include subjective factors in a structured approach, as well as controversial questions such as the importance of onsite versus offsite accident costs averted, uncertainty, and impact of public opinion. In the paper, the method is applied to include a value-impact study of the implementation of either a vented-containment system or an alternative decay heat removal system as a means for reducing risk at the Grand Gulf nuclear power plant. The results of this analysis show that the method provides considerable insight to the solution of topics of interest in the decision making area of nuclear power risk management. (orig.)

    Workplace incivility is a subtle type of deviant work behavior that is low in intensity and violates workplace norms of respect. Past research demonstrates the harmful impact of incivility on work attitudes and employee wellbeing; however, little is known about how incivility is experienced by individuals of different ethnicities and cultural orientations. In the current study, we compared the amount and impact of workplace incivility that was experienced by Hispanic and white, non-Hispanic employees. Further, we examined whether cultural dimensions of vertical and horizontal individualism and collectivism moderated the relationships between workplace incivility and work and health outcomes. A sample of 262 university employees (50% Hispanic; 63% female) provided self-reports of experienced incivility, burnout, job satisfaction, and cultural values. Although male Hispanic employees experienced more incivility, female Hispanic employees experienced less incivility than non-Hispanic employees of the same gender. Hispanic employees displayed greater resilience against the impact of incivility on job satisfaction and burnout, compared with non-Hispanic employees. Additionally, employees with strong horizontal collectivism values (emphasizing sociability) were more resilient against the impact of incivility on burnout, whereas employees with strong horizontal individualism values (emphasizing self-reliance) were more susceptible to burnout and dissatisfaction when faced with incivility. These findings suggest that employees' ethnicity and cultural values may increase or decrease their vulnerability to the impact of incivility at work. (c) 2015 APA, all rights reserved).

An action plan to change the system of local finance Ukraine in the context of fiscal decentralization on a 5­year period is proposed. The action plan envisages normalization of regulatory provisions in the area of local finance, training local government officials, development resources, monitoring and evaluating the effectiveness of the current system of local finance.

  4. Global and local emission impact assessment of distributed cogeneration systems with partial-load models

    Small-scale distributed cogeneration technologies represent a key resource to increase generation efficiency and reduce greenhouse gas emissions with respect to conventional separate production means. However, the diffusion of distributed cogeneration within urban areas, where air quality standards are quite stringent, brings about environmental concerns on a local level. In addition, partial-load emission worsening is often overlooked, which could lead to biased evaluations of the energy system environmental performance. In this paper, a comprehensive emission assessment framework suitable for addressing distributed cogeneration systems is formulated. Local and global emission impact models are presented to identify upper and lower boundary values of the environmental pressure from pollutants that would be emitted from reference technologies, to be compared to the actual emissions from distributed cogeneration. This provides synthetic information on the relative environmental impact from small-scale CHP sources, useful for general indicative and non-site-specific studies. The emission models are formulated according to an electrical output-based emission factor approach, through which off-design operation and relevant performance are easily accounted for. In particular, in order to address the issues that could arise under off-design operation, an equivalent load model is incorporated within the proposed framework, by exploiting the duration curve of the cogenerator loading and the emissions associated to each loading level. In this way, it is possible to quantify the contribution to the emissions from cogeneration systems that might operate at partial loads for a significant portion of their operation time, as for instance in load-tracking applications. Suitability of the proposed methodology is discussed with respect to hazardous air pollutants such as NO x and CO, as well as to greenhouse gases such as CO 2 .

    2009-03-01

    Full Text Available A total of ninety six growing snails of mean weight 91.23±2.4g were used to determine the effects of partial or total replacement of local fish meal, a source of protein but expensive to a less expensive, alternative source, chicken offal in the diet of growing snails. Completely randomized design was used for the study. The feeding trial had four treatments, C1, C2, C3 and C4 in which fish meal fraction of the diets was replaced at 0, 50, 75 and 100% with chicken offal respectively. The parameters taken were weight gain, feed intake. Feed conversion ratio, total feed cost, and cost per weight gain were calculated. The trial lasted for twelve weeks. Significant differences were not observed in the mean weekly feed intake of the snails in all the treatments. The mean weight gain in all the treatments were not significantly influenced by the inclusion of chicken offal in the diet (P>0.005. Total feed cost and cost/weight gain reduced as the level of the chicken offal increased while the lowest cost/weight gain was observed in C4. The inclusion of Chicken offal in all the diets had no detrimental effect on the snails in all the treatments. Based on the present results chicken offal could replace local fish meal in the diet of growing snail up to 100% and hereby reduce feed cost

    1992-02-01

    This document, written for the US Department of Energy, discusses current information and the need for future research on estimating the impacts on wages and property values that could result from people's perceptions of the risks associated with noxious facilities. Psychometric studies indicate that the US population is averse to living near noxious facilities, nuclear-related facilities in particular. Contingent valuation and hedonic studies find that the net economic impacts of proximity to noxious facilities are generally negative and often substantial. Most of these studies are limited in scope, and none estimate the impacts derived from public perceptions of such facilities. This study examines the mechanisms by which negative public perceptions result in economic impacts reflected in wages and property values. On the basis of these mechanisms, it develops a predictive model of perception-based impacts and identifies the data and methods needed to implement it. The key to predicting perception-based impacts lies in combining psychometric and hedonic methods. The reliability of psychometric measures as indicators of aversive stimuli that precipitate economic impacts can be empirically tested. To test the robustness of the findings, alternative estimation methods an be employed in the hedonic analysis. Contingent valuation methods can confirm the results.

    2013-02-01

    Fossil fuel energy has several externalities not accounted for in the retail price, including associated adverse human health impacts, future costs from climate change, and other environmental damages. Here, we quantify the economic value of health impacts associated with PM(2.5) and PM(2.5) precursors (NO(x) and SO(2)) on a per kilowatt hour basis. We provide figures based on state electricity profiles, national averages and fossil fuel type. We find that the economic value of improved human health associated with avoiding emissions from fossil fuel electricity in the United States ranges from a low of $0.005-$0.013/kWh in California to a high of $0.41-$1.01/kWh in Maryland. When accounting for the adverse health impacts of imported electricity, the California figure increases to $0.03-$0.07/kWh. Nationally, the average economic value of health impacts associated with fossil fuel usage is $0.14-$0.35/kWh. For coal, oil, and natural gas, respectively, associated economic values of health impacts are $0.19-$0.45/kWh, $0.08-$0.19/kWh, and $0.01-$0.02/kWh. For coal and oil, these costs are larger than the typical retail price of electricity, demonstrating the magnitude of the externality. When the economic value of health impacts resulting from air emissions is considered, our analysis suggests that on average, U.S. consumers of electricity should be willing to pay $0.24-$0.45/kWh for alternatives such as energy efficiency investments or emission-free renewable sources that avoid fossil fuel combustion. The economic value of health impacts is approximately an order of magnitude larger than estimates of the social cost of carbon for fossil fuel electricity. In total, we estimate that the economic value of health impacts from fossil fuel electricity in the United States is $361.7-886.5 billion annually, representing 2.5-6.0% of the national GDP.

  13. Aviation Impacts on Property Values and Management: The Case of Suvarnabhumi International Airport

    2015-07-01

    Full Text Available Many countries have developed policies and measures to deal with the external impact of aviation on the wider community. There is, however, often controversy and lack of acceptance of some measures, such as compensation, in the communities affected by aviation. Such measures are often felt to be ineffective and perceived as unfair. A clear and objective model for determining compensation would be helpful to reduce controversy. The objective of this study is therefore to examine the relationship between aviation impacts and property values in the case of Thailand's Suvarnabhumi Airport for application to the possible improvement of compensation packages. Multiple regression analysis was used to determine the relationship between five common impacts of aviation (safety, noise, scenery, air pollution, and traffic and property value change, with data from a survey of sample communities around the airport. The results, both for the overall neighborhood and for separate land used types, show that only noise and air pollution demonstrate significant negative relations with property value. The effect of noise drives a higher impact on property price than the effect of air pollution. The main contribution of this research is to improve developing country compensation models by applied measurement from regression analysis to identify factors with significant impacts, using property value change as proxy to measure the impact of the airport. For example, in the case of Thailand, a compensation model should consider noise and air pollution as the main factors rather than consider only noise contour area. The higher weight on noise should be designed to reflect land use types. Furthermore the market value of property loss should be taken into account when designing a compensation package. The survey and regression method used in this study can be adapted for finding relevant factors and suggesting appropriate compensation for other environmental and

Our expression agrees both with semi-classical results in the sine-Gordon theory and with perturbative calculations in the massive Thirring model. We use this expression to make new predictions about the large-distance asymptotic form of the two-point correlation function in the XXZ spin chain. (orig.)

    There is a thought that hourly and spacial blanks in earthquake activity contribute to earthquake occurrence probability. Based on an idea that if so, this tendency may appear also in statistical parameters of earthquake, earthquake activities in every ten years were investigated in the relation between locational distribution of inclined b values of a line relating to the number of earthquake and the magnitude, and the center focus of earthquakes which are M{ge}7.0. The field surveyed is the Japanese Islands and the peripheral ocean, and the area inside the circle with a radius of 100km with a lattice-like point divided in 1{degree} in every direction of latitude and longitude as center was made a unit region. The depth is divided by above 60km or below 60km. As a result, the following were found out: as to epicenters of earthquakes with M{ge}7.0 during the survey period of 100 years, many are in a range of b(b value){le}0.75, and sometimes they may be in a range of b{ge}0.75 in the area from the ocean near Izu peninsula to the ocean off the west Hokkaido; the position of epicenters in a range of b{le}0.75 seems not to come close to the center of contour which indicates the maximum b value. 7 refs., 2 figs.

    We present a conjecture for the exact expression of finite volume expectation values in excited states in integrable quantum field theories, which is an extension of an earlier conjecture to the case of general diagonal factorized scattering with bound states and a nontrivial bootstrap structure. The conjectured expression is a spectral expansion which uses the exact form factors and the excited state thermodynamic Bethe Ansatz as building blocks. The conjecture is proven for the case of the trace of the energy-moment tensor. Concerning its validity for more general operators, we provide numerical evidence using the truncated conformal space approach. It is found that the expansion fails to be well-defined for small values of the volume in cases when the singularity structure of the TBA equations undergoes a non-trivial rearrangement under some critical value of the volume. Despite these shortcomings, the conjectured expression is expected to be valid for all volumes for most of the excited states, and as an expansion above the critical volume for the rest.

    2008-09-01

    In the vast Travel Health literature there is still a considerable dearth on tourism's impact on local communities. This review attempts to remedy the situation. Its focus is on potential health impacts on populations living at tourist destinations outside the industrialised world. To facilitate a better understanding of how health is linked to tourism today, a brief overview of the historical and theoretical evolution of tourism is presented. Ecotourism is given special attention as it is perceived as a version of the industry that is more benign on environment and people. After discussing Indigenous Tourism, a variety of potential health implications is outlined. These follow a previously suggested classification of indirect and direct impacts, with the indirect impacts being based on economic, environmental, socio-cultural and, more recently, political impacts, and the direct impacts originating from immediate encounters between tourism and people. Finally, the urgent need for more research is highlighted, and some solutions to minimize health impact are suggested.

    Highlights: • Local impact effect of hard missile on reinforced concrete targets has been studied. • Review of empirical formulation for predicting local response carried out. • Numerical simulation of experimental test of Kojima (1991) carried out. • Divergence of FE results with those obtained using emperical formulations. • Close match of numerical simulation results with experimental data. - Abstract: Concrete containment walls and internal concrete barrier walls of a Nuclear Power Plant safety related structures are often required to be designed for externally and internally generated missiles. Potential missiles include external extreme wind generated missiles, aircraft crash and internal accident generated missiles such as impact due to turbine blade failure and steel pipe missiles resulting from pipe break. The objective of the present paper is to compare local missile impact effects on reinforced concrete target using available empirical formulations with those obtained using LS-DYNA numerical simulation. The use of numerical simulations for capturing the transient structural response has become increasingly used for structural design against impact loads. They overcome the limits of applicability of the empirical formulae and also provide information on stress and deformation fields, which may be used to improve the resistance of the concrete. Finite element (FE) analyses of an experimental impact problem reported by Kojima (1991) are carried out that are able to capture the missile impact effects; in terms of local and global damage. The continuous surface cap model has been used for modelling concrete behaviour. A range of missile velocity has been considered to simulate local missile impact phenomenon and modes of failure and to capture the concrete response from elastic to plastic fracture. A comparison is then made between the empirical formulations, numerical simulation results, and available experimental results of slab impact tests

  1. Global Health Diplomacy, "San Francisco Values," and HIV/AIDS: From the Local to the Global.

    San Francisco has a distinguished history as a cosmopolitan, progressive, and international city, including extensive associations with global health. These circumstances have contributed to new, interdisciplinary scholarship in the field of global health diplomacy (GHD). In the present review, we describe the evolution and history of GHD at the practical and theoretical levels within the San Francisco medical community, trace related associations between the local and the global, and propose a range of potential opportunities for further development of this dynamic field. We provide a historical overview of the development of the "San Francisco Model" of collaborative, community-owned HIV/AIDS treatment and care programs as pioneered under the "Ward 86" paradigm of the 1980s. We traced the expansion and evolution of this model to the national level under the Ryan White Care Act, and internationally via the President's Emergency Plan for AIDS Relief. In parallel, we describe the evolution of global health diplomacy practices, from the local to the global, including the integration of GHD principles into intervention design to ensure social, political, and cultural acceptability and sensitivity. Global health programs, as informed by lessons learned from the San Francisco Model, are increasingly aligned with diplomatic principles and practices. This awareness has aided implementation, allowed policymakers to pursue related and progressive social and humanitarian issues in conjunction with medical responses, and elevated global health to the realm of "high politics." In the 21st century, the integration between diplomatic, medical, and global health practices will continue under "smart global health" and GHD paradigms. These approaches will enhance intervention cost-effectiveness by addressing and optimizing, in tandem with each other, a wide range of (health and non-health) foreign policy, diplomatic, security, and economic priorities in a synergistic manner

    Full Text Available Abstract This paper examines the burgeoning impact of peer-to-peer (P2P traffic IP video traffic. High-quality IPTV or Internet TV has high-bandwidth requirements, and P2P IP video could severely strain broadband networks. A model for the popularity of video titles is given, showing that some titles are very popular and will often be available locally; making localized P2P attractive for video titles.

    Full Text Available This paper examines the burgeoning impact of peer-to-peer (P2P traffic IP video traffic. High-quality IPTV or Internet TV has high-bandwidth requirements, and P2P IP video could severely strain broadband networks. A model for the popularity of video titles is given, showing that some titles are very popular and will often be available locally; making localized P2P attractive for video titles. The bandwidth impacts of localizing P2P video to try and keep traffic within a broadband access network area or within a broadband access aggregation network area are examined. Results indicate that such highly localized P2P video can greatly lower core bandwidth usage.

    In recent years, many cities have joined transnational municipal climate networks (TMCNs), which were set up in response to climate change. Despite the fact that some of these TMCNs have been active for more than two decades, there has been no systematic investigation of the networks’ impact on local climate governance. In this article we attempt to answer if and how local climate governance has been influenced by municipalities’ memberships in TMCNs. Our assessment is based on an online surv...

    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...

    The recent drafting of the Sustainable Development Goals challenges the research community to rethink the traditional approach to global health and provides the opportunity for science, technology, engineering, and mathematical (STEM) disciplines, particularly engineering, to demonstrate their benefit to the field. Higher education offers a platform for engineering to intersect with global health research through interdisciplinary partnerships among international universities that provide excellence in education, attract nontraditional STEM students, and foster a sense of innovation. However, a traditional lack of engineering-global health collaborations, as well as limited faculty and inadequate STEM research funding in low-income countries, has stifled progress. Still, the impact of higher education on development efforts holds great potential. This value will be realized in low-income countries through strengthening local capacity, supporting innovation through educational initiatives, and encouraging the inclusion of women and minorities in STEM programs. Current international university-level partnerships are working towards integrating engineering into global health research and strengthening STEM innovation among universities in low-income countries, but more can be done. Global health research informs sustainable development, and through integrating engineering into research efforts through university partnerships, we can accelerate progress and work towards a healthier future for all.

    Full Text Available We analyzed the impact of religious affiliation on the ethical and environmental values of Spanish environmental activists, based on an internet survey and a working seminar held with representatives of major environmental non-government organizations (ENGO of Spain. Respondents’ religious affiliations were significantly different compared with those of Spanish society in general, with a much higher proportion of Buddhists, agnostics and atheists and a lower proportion of Catholics. Strict environmental values of ENGOs activists did not show significant differences between the religious groups, which imply that religious beliefs did not impact actual environmental values. However, they did have a significant influence on the activists’ opinions on other bioethical issues. We found that Catholics and believers of other religions were more in favor than agnostics and atheists of introducing ethical limits on abortion, euthanasia or human embryo manipulation.

    Purpose: To present the results of a patient dose evaluation program in pediatric cardiology and propose local diagnostic reference levels (DRLs) for different types of procedure and age range, in addition to suggesting approaches to correlate patient dose values with patient weight. This study was the first conducted in Latin America for pediatric interventional cardiology under the auspices of the International Atomic Energy Agency. Methods: Over three years, the following data regarding demographic and patient dose values were collected: age, gender, weight, height, number of cine series, total number of cine frames, fluoroscopy time (FT), and two dosimetric quantities, dose-area product (DAP) and cumulative dose (CD), at the patient entrance reference point. The third quartile values for FT, DAP, CD, number of cine series, and the DAP/body weight ratio were proposed as the set of quantities to use as local DRLs. Results: Five hundred and seventeen patients were divided into four age groups. Sample sizes by age group were 120 for <1 yr; 213 for 1 to <5 yr; 82 for 5 to <10 yr; and 102 for 10 to <16 yr. The third quartile values obtained for DAP by diagnostic and therapeutic procedures and age range were 1.17 and 1.11 Gy cm{sup 2} for <1 yr; 1.74 and 1.90 Gy cm{sup 2} for 1 to <5 yr; 2.83 and 3.22 Gy cm{sup 2} for 5 to <10 yr; and 7.34 and 8.68 Gy cm{sup 2} for 10 to <16 yr, respectively. The third quartile value obtained for the DAP/body weight ratio for the full sample of procedures was 0.17 (Gy cm{sup 2}/kg) for diagnostic and therapeutic procedures. Conclusions: The data presented in this paper are an initial attempt at establishing local DRLs in pediatric interventional cardiology, from a large sample of procedures for the standard age bands used in Europe, complemented with the values of the ratio between DAP and patient weight. This permits a rough estimate of DRLs for different patient weights and the refining of these values for the age bands when there

    2016-12-01

    Full Text Available The value added tax represents one of the most important sources of state budget revenues of EU Member States. The basic value added tax rate is in the EU currently between 15% in Luxembourg to 27% applied in Hungary. The revenues from this tax represent an average of 17.5% of all tax revenues of EU countries and create an average GDP of 7.0% (year 2016, EU 28. As revenues from value added tax represent a stable income of state budget, the legislative changes in the system of value added tax, mainly its reductions as well as its imposition on groceries, can significantly influence further macroeconomic development. In the last year, the government of the Slovak Republic implemented changes in universal indirect taxing in such way that in addition to the standard value added tax rate of 20%, the Act No. 268/2015 on Value added tax adopted in 2016 a decreased value added tax rate of 10% on selected groceries, in order to support domestic producers and reduce the tax burden of low-income and middle-income groups. According to the European Commission (2007, the reduced rate of value added tax in selected cases has its justification and importance in the country's economy. The aim of this paper is to analyse the economic impact of the applied reduced value added tax on food in the Slovak Republic in the context of household expenditures and revenues of the state budget.

  18. The Strategic Impact of Corporate Responsibility and Criminal Networks on Value Co-Creation

    Peter Zettinig

    2011-02-01

    Full Text Available This article is motivated by the increasing concern about the ever-declining security of pharmaceutical products due to the abundance of counterfeit network actors. We argue that if networks are effective mechanisms for criminal organizations to infiltrate into any value chain, then networks should also work for responsible businesses in their quests to counter this phenomenon of value destruction, which is ultimately detrimental to the value co-creation process. Thus, this article demonstrates a nuanced understanding of the strategic impact of corporate responsibility of actors in networks on value co-creation. The current discourse on value co-creation in business networks is structured in such a way that it precludes its inherent corporate responsibility component even though they are not mutually exclusive. Moreover, research on value co-creation aimed at the proactive and responsible defence of a network substance via value co-protection has been mostly scant. We propose a model of value-optimization through value co-protection and ethical responsibility. This way of theorizing has several implications for both policy making and managerial decision making in the pharmaceutical industry and beyond.

    Full Text Available Fiber Bragg Grating (FBG sensors have been increasingly used in the field of Structural Health Monitoring (SHM in recent years. In this paper, we proposed an impact localization algorithm based on the Empirical Mode Decomposition (EMD and Particle Swarm Optimization-Support Vector Machine (PSO-SVM to achieve better localization accuracy for the FBG-embedded plate. In our method, EMD is used to extract the features of FBG signals, and PSO-SVM is then applied to automatically train a classification model for the impact localization. Meanwhile, an impact monitoring system for the FBG-embedded composites has been established to actually validate our algorithm. Moreover, the relationship between the localization accuracy and the distance from impact to the nearest sensor has also been studied. Results suggest that the localization accuracy keeps increasing and is satisfactory, ranging from 93.89% to 97.14%, on our experimental conditions with the decrease of the distance. This article reports an effective and easy-implementing method for FBG signal processing on SHM systems of the composites.

This permits a rough estimate of DRLs for different patient weights and the refining of these values for the age bands when there may be large differences in child size. These DRLs were obtained at the largest pediatric hospital in Chile, with an active optimization program, and could be used by other hospitals in the Latin America region to compare their current patient dose values and determine whether corrective action is appropriate. © 2015 American Association of Physicists in Medicine.

    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.

  5. Values of Catholic science educators: Their impact on attitudes of science teaching and learning

    Science.gov (United States)

    DeMizio, Joanne Greenwald

    This quantitative study examined the associations between the values held by middle school science teachers in Catholic schools and their attitudes towards science teaching. A total of six value types were studied---theoretical, economic, aesthetic, social, political, and religious. Teachers can have negative, positive, or neutral attitudes towards their teaching that are linked to their teaching practices and student learning. These teachers' attitudes may affect their competence and have a subsequent impact on their students' attitudes and dispositions towards science. Of particular interest was the relationship between science teaching attitudes and religious values. A non-experimental research design was used to obtain responses from 54 teachers with two survey instruments, the Science Teaching Attitude Scale II and the Allport-Vernon-Lindzey Study of Values. Stepwise multiple regression analysis showed that political values were negatively associated with attitudes towards science teaching. Data collected were inconsistent with the existence of any measurable association between religious values and attitudes towards science teaching. This study implies that science teacher preparation programs should adopt a more contextual perspective on science that seeks to develop the valuation of science within a cultural context, as well as programs that enable teachers to identify the influence of their beliefs on instructional actions to optimize the impact of learning new teaching practices that may enhance student learning.

  6. The impact of local black residents' socioeconomic status on white residents' racial views.

    2014-01-01

    This paper extends the study of contextual influences on racial attitudes by asking how the SES of the local black community shapes the racial attitudes of local whites. Using responses to the 1998-2002 General Social Surveys merged with year 2000 census data, we compare the influences of black educational and economic composition on white residents' attitudes. Finally, the independence of these effects from the impact of white contextual SES is assessed. Across three dimensions of racial attitudes, white residents' views are more positive in localities where the black population contains more college graduates. However, such localities tend also to have highly educated white populations, as well as higher incomes among blacks and whites, and the multiple influences are inseparable. In contrast, many racial attitude measures show an independent effect of black economic composition, white residents reporting more negative views where the local African American community is poorer.

    For locally advanced rectal cancer, response to neoadjuvant radiation has been associated with improved outcomes but has not been well characterized in general practice. The goals of this study were to describe disease response rates after neoadjuvant treatment and to evaluate the association between disease response and survival. Retrospective cohort study of patients aged 18-80 y with clinical stage II and III rectal adenocarcinoma in the National Cancer Database (2006-2012). All patients underwent radical resection after neoadjuvant treatment. Treatment responses were defined as follows: no tumor response; intermediate-T and/or N downstaging with residual disease; and complete-ypT0N0. Multivariable, multinomial regression was used to evaluate the association between neoadjuvant radiation use and disease response. Multivariable Cox regression was used to evaluate the association between disease response and overall risk of death. Among 12,024 patients, 12% had a complete and 30% an intermediate response. Neoadjuvant chemotherapy alone was less likely to achieve an intermediate (relative risk ratio: 0.70 [0.56-0.88]) or a complete response (relative risk ratio: 0.59 [0.41-0.84]) relative to neoadjuvant radiation. Tumor response was associated with improved 5-y overall survival (complete = 90.2%, intermediate = 82.0%, no response = 70.5%; log-rank, P < 0.001). Complete and intermediate pathologic responses were associated with decreases in risk of death (hazard ratio: 0.40 [0.34-0.48] and 0.63 [0.57-0.69], respectively) compared to no response. Primary tumor and nodal response were independently associated with decreased risk of death. Neoadjuvant radiation is associated with treatment response, and pathologic response is associated with improved survival. Pathologic response may be an early benchmark for the oncologic effectiveness of neoadjuvant treatment. Published by Elsevier Inc.

    Battelle has conducted a three-year effort, funded by the U. S Department of Energy's (DOE) Office of Technology Development, to involve stakeholders in evaluating innovative technologies to clean up volatile organic compound (VOC) contamination at arid sites. Stakeholders have been encouraged to participate in the demonstration of these innovative technologies in order to improve decisions made by DOE and its contractors about technology development, demonstration, and deployment. The basic approach is to identify people and organizations with a stake in the remediation process, and hence in the demonstration of innovative technologies. Stakeholders have included public interest group and environmental group representatives, regulators, technology users, Native Americans, Hispanic community members, and local elected officials. These people are invited to be involved and they are presented with substantive information about the technologies. Their input in terms of identifying issues and concerns, defining the kinds of information needed from the demonstrations, and assessing the acceptability of the technologies for deployment, will help ensure that only broadly promising technologies are carried forward. This approach is designed to increase the likelihood of successful deployment of the new technologies needed to accomplish environmental restoration throughout the DOE complex and at private facilities. The hypothesis in conducting this regional stakeholder involvement program is that there will be different data requirements for different sites due to geographical, institutional, programmatic, and cultural differences at the sites. Identifying the broadest set of data requirements, collecting this information during the technology demonstration, and providing the results of the demonstration to stakeholders will enhance the acceptance of the technology at these sites and, thereby, enhance the technology's deployability

    The Thai Public Health Act 1992 required the Thai local governments to issue respective regulations to take control of any possible health-hazard related activities, both from commercial and noncommercial sources. Since 1999, there has been centrally decentralized of power to a new form of local government establishment, namely Sub-district Administrative Organization (SAO). The SAO is asmall-scale local governing structure while its legitimate function is for community services, including control of health impact related activities. Most elected SAO administrators and officers are new and less experience with any of public health code of practice, particularly on health-hazard control. This action research attempted to introduce and apply a participatory health impact assessment (HIA) tool for the development of SAO health-hazard control regulation. The study sites were at Ban Meang and Kok See SAOs, Khon Kaen Province, Thailand, while all intervention activities conducted during May 2005-April 2006. A set of cooperative activities between researchers and community representatives were planned and organized by; surveying and identifying place and service base locally causing local environmental health problems, organizing community participatory workshops for drafting and proposing the health-hazard control regulation, and appropriate practices for health-hazard controlling measures. This action research eventually could successfully enable the SAO administrators and officers understanding of local environmental-related health problem, as well as development of imposed health-hazard control regulation for local community.

  10. Impact of lengthening open water season on food security in Alaska coastal communities: Global impacts may outweigh local "frontline" effects

    Using ice concentration data from the Alaska Sea Ice Atlas from 1953-2013 for selected communities in Alaska, we find a consistent trend toward later freeze up and earlier breakup, leading a lengthened open water period. Such changes are often considered to bring a variety of "frontline" local impacts to Arctic coastal communities such as increased rates of coastal erosion. However, direct consequences of these changes to local food security (e.g. through impacts on subsistence activities and marine transport of goods) may be outweighed at least in the short term by the effects of large scale Arctic sea ice change coupled with global oil markets. For example, a later freeze-up might delay local hunters' transition from boats to snow-machines, but whether this trend will affect hunting success, especially in the next few years, is uncertain. Likewise, the magnitude of change in open water season length is unlikely to be sufficient to increase the frequency with which communities are served by barges. However, an expanding open water season throughout the Arctic has implications for the global economy, which can have indirect effects on local communities. In the Chukchi and Beaufort Seas, where rapid sea ice change has been accompanied by increased interest in oil and gas development, the U.S. Bureau of Ocean Energy Management currently requires drilling operations to cease 38 days prior to freeze up. Taking this into account, the lengthening open water season has effectively extended the drilling season for oil companies by 184% since the 1950s. If oil development goes ahead, local communities will likely experience a range of indirect impacts on food security due to increased vessel traffic and demand on infrastructure coupled with changes in local economies and employment opportunities. Increased likelihood of an oil spill in coastal waters also poses a significant threat to local food security. Thus, while Arctic coastal communities are already experiencing

    Purpose: To evaluate expression of a panel of molecular markers, including p53, p21, MLH1, MSH2, MIB-1, thymidylate synthase, epidermal growth factor receptor (EGFR), and tissue vascular endothelial growth factor (VEGF), before and after treatment in patients treated with neoadjuvant chemoradiotherapy for locally advanced rectal cancer, to correlate the constitutive profile and dynamics of expression with pathologic response and outcome. Methods and Materials: Expression of biomarkers was evaluated by immunohistochemistry in tumor samples from 91 patients with clinical Stage II and III rectal cancer treated with preoperative pelvic radiotherapy (50 Gy) plus concurrent 5-fluorouracil by continuous intravenous infusion. Results: A pathologic complete remission was observed in 14 patients (15.4%). Patients with MLH1-positive tumors had a higher pathologic complete response rate (24.3% vs. 9.4%; p = 0.055). Low expression of constitutive p21, absence of EGFR expression after chemoradiotherapy, and high Dworak's tumor regression grade (TRG) were significantly associated with improved disease-free survival and overall survival. A high MIB-1 value after chemoradiotherapy was significantly associated with worse overall survival. Multivariate analysis confirmed the prognostic value of constitutive p21 expression as well as EGFR expression and MIB-1 value after chemoradiotherapy among patients not achieving TRG 3-4. Conclusions: In our study, we observed the independent prognostic value of EGFR expression after chemoradiotherapy on disease-free survival. Moreover, our study suggests that a constitutive high p21 expression and a high MIB-1 value after neoadjuvant chemoradiotherapy treatment could predict worse outcome in locally advanced rectal cancer

  12. Values, animal symbolism, and human-animal relationships associated to two threatened felids in Mapuche and Chilean local narratives

    2013-01-01

    Background The Chilean temperate rainforest has been subjected to dramatic fragmentation for agriculture and forestry exploitation. Carnivore species are particularly affected by fragmentation and the resulting resource use conflicts with humans. This study aimed at understanding values and human-animal relationships with negatively perceived threatened carnivores through the disclosure of local stories and Mapuche traditional folktales. Methods Our mixed approach comprised the qualitative analysis of 112 stories on the kodkod cat (Leopardus guigna) and the puma (Puma concolor) collected by students (9-14 years) from 28 schools in the Araucania region within their family contexts, 10 qualitative in-depth interviews with indigenous Mapuche people, 35 traditional Mapuche legends, and the significance of naming found in ethnographic collections. Results We revealed a quasi-extinction of traditional tales in the current knowledge pool about pumas and kodkods, local anecdotes, however, were present in significant numbers. Values associated to both felids were manifold, ranging from negativistic to positive values. While pumas played an important role in people’s spirituality, negative mythological connotations persisted in kodkod stories. Four prominent relationships were derived: (1) Both felids represent threats to livestock, pumas even to life, (2) both felids are symbols for upcoming negative events, (3) pumas are spiritual creatures, and (4) kodkods are threatened by humans. Recommendations are provided for stimulating new ways of perceiving unpopular and threatened carnivores among those who live in vicinity to them. PMID:23764186

    Full Text Available Mergers and acquisitions are ways used by banks to improve their profitability and to obtain other advantages. The purpose of this study is to analyze the impact of mergers and acquisitions on the performance of the bidder bank. For this study, I have chosen to research the impact of acquisitions and mergers of Erste Group during 2000-2011, considering the target bank is in Central and Eastern Europe. Using the event study methodology, the result of the study shows that a merger or an acquisition does not improve the value market of the shares of the bidder bank.

    The validity, reliability and cross-country comparability of summary measures of population health (SMPH) have been persistently debated. In this debate, the measurement and valuation of nonfatal health outcomes have been defined as key issues. Our goal was to quantify and decompose international differences in health expectancy based on health-related quality of life (HRQoL). We focused on the impact of value set choice on cross-country variation. We calculated Quality Adjusted Life Expectancy (QALE) at age 20 for 15 countries in which EQ-5D population surveys had been conducted. We applied the Sullivan approach to combine the EQ-5D based HRQoL data with life tables from the Human Mortality Database. Mean HRQoL by country-gender-age was estimated using a parametric model. We used nonparametric bootstrap techniques to compute confidence intervals. QALE was then compared across the six country-specific time trade-off value sets that were available. Finally, three counterfactual estimates were generated in order to assess the contribution of mortality, health states and health-state values to cross-country differences in QALE. QALE at age 20 ranged from 33 years in Armenia to almost 61 years in Japan, using the UK value set. The value sets of the other five countries generated different estimates, up to seven years higher. The relative impact of choosing a different value set differed across country-gender strata between 2% and 20%. In 50% of the country-gender strata the ranking changed by two or more positions across value sets. The decomposition demonstrated a varying impact of health states, health-state values, and mortality on QALE differences across countries. The choice of the value set in SMPH may seriously affect cross-country comparisons of health expectancy, even across populations of similar levels of wealth and education. In our opinion, it is essential to get more insight into the drivers of differences in health-state values across populations. This

  17. Reliability based impact localization in composite panels using Bayesian updating and the Kalman filter

    Science.gov (United States)

    Morse, Llewellyn; Sharif Khodaei, Zahra; Aliabadi, M. H.

    2018-01-01

    In this work, a reliability based impact detection strategy for a sensorized composite structure is proposed. Impacts are localized using Artificial Neural Networks (ANNs) with recorded guided waves due to impacts used as inputs. To account for variability in the recorded data under operational conditions, Bayesian updating and Kalman filter techniques are applied to improve the reliability of the detection algorithm. The possibility of having one or more faulty sensors is considered, and a decision fusion algorithm based on sub-networks of sensors is proposed to improve the application of the methodology to real structures. A strategy for reliably categorizing impacts into high energy impacts, which are probable to cause damage in the structure (true impacts), and low energy non-damaging impacts (false impacts), has also been proposed to reduce the false alarm rate. The proposed strategy involves employing classification ANNs with different features extracted from captured signals used as inputs. The proposed methodologies are validated by experimental results on a quasi-isotropic composite coupon impacted with a range of impact energies.

  1. The financial impact of hospitals on the local economy--2 new factors.

    Science.gov (United States)

    Rotarius, Timothy; Liberman, Aaron

    2014-01-01

    This research effort presents a descriptive analysis of the financial impact that several hospitals have on their local economy. An earlier study published by the authors included 3 distinct, yet overlapping components of financial impact: (1) the hospital system as a major health care provider, (2) the hospital system as a large employer, and (3) the hospital system as an entity whose employees contribute greatly to their local community. This new study added additional financial impact factors: (4) the hospital system as an organization committed to major construction projects in pursuit of its health services mission, and (5) the hospital system as an entity that pays taxes to government agencies. The inextricable relationship of these 5 categories both increases and enhances the impact of the hospital system on the local region. The results of this updated and expanded analysis suggest strongly that the hospital system represents 1 of the primary contributors to the economy of the region. The hospital system adds $3 billion to the $28 billion local economy, which means that the hospital system and its employees are responsible for 10.7% of the total economic prowess of the region.

    Hydropower is an important service provided by ecosystems. We surveyed all the hydropower plants in the Zagunao River Basin, Southwest China. Then, we assessed the hydropower service by using the InVEST (The Integrated Value and Tradeoff of Ecosystem Service Tools) model. Finally, we discussed the impact on ecological compensation. The results showed that: 1) hydropower service value of ecosystems in the Zagunao River Basin is 216.29 Euro/hm(2) on the average, of which the high-value area with more than 475.65 Euro/hm(2) is about 750.37 km(2), accounting for 16.12% of the whole watershed, but it provides 53.47% of the whole watershed service value; 2) ecosystem is an ecological reservoir with a great regulation capacity. Dams cannot completely replace the reservoir water conservation function of ecosystems, and has high economic and environmental costs that must be paid as well. Compensation for water conservation services should become an important basis for ecological compensation of hydropower development. 3) In the current PES cases, the standard of compensation is generally low. Cascade development makes the value of upstream ecosystem services become more prominent, reflecting the differential rent value, and the value of ecosystem services should be based on the distribution of differentiated ecological compensation.

    Cerebral blood flow (CBF) and oxygen consumption (CMRO/sub 2/) have been measured locally using positron emission tomography (PET) in 25 patients (34 studies) with recent cerebral infarction. The data analysis yielded threshold values for CBF and CMRO/sub 2/ that reliably separated the brain areas spontaneously evolving to necrosis from those maintaining integrity (as determined by C.T. Scanning) but still showing significant changes in CBF and/or CMRO/sub 2/. These results suggest the potential use of PET for estimation of tissue prognosis in recent cerebral infarction.

    The calculations which underlie efforts to balance marketing spending on customer acquisition and customer retention are usually based on either single- period customer profitability or forecasts of customer lifetime value (CLTV). This paper argues instead for risk-adjusted CLTV, which is termed the economic value (EV) of a customer, as the means for marketing to assess both customer profitability and shareholder value gains.

    Although anemia is considered to be a contributor to intra-tumoral hypoxia and tumor resistance to ionizing radiation in cancer patients, the impact of pretreatment anemia on local control after neoadjuvant concurrent chemoradiotherapy (NACRT) and surgery for rectal cancer remains unclear. We reviewed the records of 247 patients with locally advanced rectal cancer who were treated with NACRT followed by curative-intent surgery. The patients with anemia before NACRT (36.0%, 89/247) achieved less pathologic complete response (pCR) than those without anemia (p = 0.012). The patients with pretreatment anemia had worse 3-year local control than those without pretreatment anemia (86.0% vs. 95.7%, p = 0.005). Multivariate analysis showed that pretreatment anemia (p = 0.035), pathologic tumor and nodal stage (p = 0.020 and 0.032, respectively) were independently significant factors for local control. Pretreatment anemia had negative impacts on pCR and local control among patients who underwent NACRT and surgery for rectal cancer. Strategies maintaining hemoglobin level within normal range could potentially be used to improve local control in rectal cancer patients.

    Biomass burning, including wildfires and prescribed burns, strongly impact the global carbon cycle and are of increasing concern due to the potential impacts on ambient air quality. This modelling study focuses on the evolution of carbonaceous compounds during a prescribed burning experiment and assesses the impacts of burning on local to regional air quality. The Community Multiscale Air Quality (CMAQ) model is used to conduct 4 and 2 km grid resolution simulations of prescribed burning experiments in southeast Washington state and western Idaho state in summer 2013. The ground and airborne measurements from the field experiment are used to evaluate the model performance in capturing surface and aloft impacts from the burning events. Phase partitioning of organic compounds in the plume are studied as it is a crucial step towards understanding the fate of carbonaceous compounds. The sensitivities of ambient concentrations and deposition to emissions are conducted for organic carbon, elemental carbon and ozone to estimate the impacts of fire on air quality.

  13. ROLE CONFLICT AND ROLE AMBIGUITY ON LOCAL GOVERNMENT INTERNAL AUDITORS: THE DETERMINANT AND IMPACTS

    Directory of Open Access Journals (Sweden)

    Agil Novriansa

    2016-01-01

    Full Text Available The bureaucratic reform at the local government level in Indonesia that was instituted in 2012 has turned local government internal auditors into an important part of government governance systems. The role of local government internal auditors has been expanded to include not only the area of audit oversight, but also the areas of anti-corruption-related and consulting activities. These fundamental changes may potentially induce role conflict and role ambiguity among internal auditors. The objective of this study is to examine empirically the determinants and consequences of role conflict and role ambiguity among local government internal auditors. More specifically, this study attempts to examine the extent to which formalization determines role conflict and role ambiguity; it further tests the impact of role conflict and role ambiguity on commitment to independence and job performance. Questionnaires were distributed to 248 local government internal auditors from 12 Regional Inspectorates in the provinces of Yogyakarta, South Sumatra, and East Java. A total of 176 responses were received, and 124 useable responses from the 176 responses were analysed to test the hypotheses. Using Structural Equation Modelling-Partial Least Square the results show that: formalization is negatively related to role conflict and role ambiguity; role ambiguity has a negative impact on commitment to independence; role conflict has a positive impact on job performance; and role ambiguity has a negative impact on job performance. These findings serve as important external validity evidence on the phenomena associated with role conflict and role ambiguity that occur in the public sector, especially among internal auditors at local government institutions.

  14. Identifying the Relevant Local Population for Environmental Impact Assessments of Mobile Marine Fauna

    2017-05-01

    Full Text Available Environmental impact assessments must be addressed at a scale that reflects the biological organization for the species affected. It can be challenging to identify the relevant local wildlife population for impact assessment for those species that are continuously distributed and highly mobile. Here, we document the existence of local communities of Indo-Pacific bottlenose dolphins (Tursiops aduncus inhabiting coastal and estuarine waters of Perth, Western Australia, where major coastal developments have been undertaken or are proposed. Using sighting histories from a 4-year photo-identification study, we investigated fine-scale, social community structure of dolphins based on measures of social affinity, and network (Half-Weight Index—HWI, preferred dyadic association tests, and Lagged Association Rates—LAR, home ranges, residency patterns (Lagged Identification Rates—LIR, and genetic relatedness. Analyses revealed four socially and spatially distinct, mixed-sex communities. The four communities had distinctive social patterns varying in strength, site fidelity, and residency patterns. Overlap in home ranges and relatedness explained little to none of the association patterns between individuals, suggesting complex local social structures. The study demonstrated that environmental impact assessments for mobile, continuously distributed species must evaluate impacts in light of local population structure, especially where proposed developments may affect core habitats of resident communities or sub-populations. Here, the risk of local extinction is particularly significant for an estuarine community because of its small size, limited connectivity with adjacent communities, and use of areas subject to intensive human use. In the absence of information about fine-scale population structure, impact assessments may fail to consider the appropriate biological context.

    The apparent diffusion coefficient (ADC) is increasingly used as a quantitative biomarker in oncological imaging. ADC calculation is based on raw diffusion-weighted imaging (DWI) data, and multiple post-processing methods (PPMs) have been proposed for this purpose. We investigated whether PPM has an impact on final ADC values. Sixty-five lesions scanned with a standardized whole-body DWI-protocol at 3 T served as input data (EPI-DWI, b-values: 50, 400 and 800 s/mm{sup 2}). Using exactly the same ROI coordinates, four different PPM (ADC{sub 1}-ADC{sub 4}) were executed to calculate corresponding ADC values, given as [10{sup -3} mm{sup 2}/s] of each lesion. Statistical analysis was performed to intra-individually compare ADC values stratified by PPM (Wilcoxon signed-rank tests: α = 1 %; descriptive statistics; relative difference/∇; coefficient of variation/CV). Stratified by PPM, mean ADCs ranged from 1.136-1.206 *10{sup -3} mm{sup 2}/s (∇ = 7.0 %). Variances between PPM were pronounced in the upper range of ADC values (maximum: 2.540-2.763 10{sup -3} mm{sup 2}/s, ∇ = 8 %). Pairwise comparisons identified significant differences between all PPM (P ≤ 0.003; mean CV = 7.2 %) and reached 0.137 *10{sup -3} mm{sup 2}/s within the 25th-75th percentile. Altering the PPM had a significant impact on the ADC value. This should be considered if ADC values from different post-processing methods are compared in patient studies. (orig.)

    2005-01-01

    This PowerPoint presentation examined challenges in the economic valuation of environmental changes within the context of formal real estate markets. It was proposed that some values that are expressed in markets can be affected by environmental changes and should be used in resource development land assessments. Details of indirect market valuation and revealed preference methods were reviewed. An outline of hedonic pricing was presented. It was noted that hedonic pricing can be used with other market values and prices such as tourism, art prices and hotel prices, where multivariate regression techniques are used and regression coefficients reveal information on the implicit prices of certain characteristics. Property value examples in the environmental economics literature were reviewed. A case study using data from eco-terrorism costs was presented. Issues concerning sour gas facilities were discussed with reference to public anxiety over hydrogen sulfide (H 2 S) toxicity and flares. Concerns over health risks and negative amenity impacts were discussed. The impacts of sour gas facilities on property values of residential acreages in and around Calgary were considered, and a map of the study area was presented. An outline of emergency plan response zones was provided. Price effects of industry facilities were presented, including marginal and cumulative impacts on price. It was concluded that oil and gas activities have significant impacts on rural residential property prices, but that industry members currently report that there is little to no effect. It was suggested that the research presented in this paper could be used to assess levels of compensation. tabs., figs

    Global climate change presents a two-pronged threat to coral reef ecosystems: increasing sea surface temperatures will increase the likelihood of episodic bleaching events, while increasing ocean carbon dioxide concentrations will change the carbonate chemistry that drives coral growth. Because coral reefs have important societal as well as ecological benefits, climate change mitigation policies that ameliorate these impacts may create substantial economic value. We present a model that evaluates both the ecological and the economic impacts of climate change on coral reefs in the United States. We use a coral reef mortality and bleaching model to project future coral reef declines under a range of climate change policy scenarios for south Florida, Puerto Rico and Hawaii. Using a benefits transfer approach, the outputs from the physical model are then used to quantify the economic impacts of these coral reef declines for each of these regions. We find that differing climate change trajectories create substantial changes in projected coral cover and value for Hawaii, but that the ecological and economic benefits of more stringent emissions scenarios are less clear for Florida and Puerto Rico. Overall, our results indicate that the effectiveness of climate change mitigation policies may be region-specific, but that these policies could result in a net increase of nearly $10 billion in economic value from coral reef-related recreational activities alone, over the 21st century.

    A modification of the original b-value (Gutenberg-Richter parameter) is proposed to evaluate local damage of reinforced concrete structures subjected to dynamical loads via the acoustic emission (AE) method. The modification, shortly called energy b-value, is based on the use of the true energy of the AE signals instead of its peak amplitude, traditionally used for the calculation of b-value. The proposal is physically supported by the strong correlation between the plastic strain energy dissipated by the specimen and the true energy of the AE signals released during its deformation and cracking process, previously demonstrated by the authors in several publications. AE data analysis consisted in the use of guard sensors and the Continuous Wavelet Transform in order to separate primary and secondary emissions as much as possible according to particular frequency bands. The approach has been experimentally applied to the AE signals coming from a scaled reinforced concrete frame structure, which was subjected to sequential seismic loads of incremental acceleration peak by means of a 3 × 3 m2 shaking table. For this specimen two beam-column connections-one exterior and one interior-were instrumented with wide band low frequency sensors properly attached on the structure. Evolution of the energy b-value along the loading process accompanies the evolution of the severe damage at the critical regions of the structure (beam-column connections), thus making promising its use for structural health monitoring purposes.

    Depression causes significant functional impairment in sufferers and often leads to adverse employment outcomes for working individuals. Recovery from depression has been associated with better employment outcomes at one year. The study s goals were to assess a primary care depression intervention s impact on subsequent employment and workplace conflict outcomes in employed patients with depression. In 1996-1997, the study enrolled 262 employed patients with depression from twelve primary care practices located across ten U.S. states; 219 (84%) of the patients were followed at one year. Intent-to-treat analyses assessing intervention effects on subsequent employment and workplace conflict were conducted using logistic regression models controlling for individual clinical and sociodemographic characteristics, job classification and local employment conditions. To meet criteria for subsequent employment, persons working full-time at baseline had to report they were working full-time at follow-up and persons working part-time at baseline had to report working part-/full-time at follow-up. Workplace conflict was measured by asking patients employed at follow-up whether, in the past year, they had arguments or other difficulties with people at work . Findings showed that 92.1% of intervention patients met criteria for subsequent employment at one year, versus 82.0% of usual care patients (c2=4.42, p=.04). Intervention patients were less likely than usual care patients to report workplace conflict in the year following baseline (8.1% vs. 18.9%, respectively; c2=4.11; p=.04). The intervention s effect on subsequent employment was not mediated by its effect on workplace conflict. The intervention significantly improved employment outcomes and reduced workplace conflict in depressed, employed persons at one year. Economic implications for employers related to reduced turnover costs, for workers related to retained earnings, and for governments related to reduced

    To date there have been few systematic efforts to uncover the criteria that local stakeholders use to perceive of and make judgments about the severity of wildfire impacts to the social-ecological systems they are a part of. The study presented here sought to uncover expanded understandings of perceived social and ecological impacts from a wildfire in rural Montana and the underlying causes for those perceived impacts. Such efforts could lead to more comprehensive social impact assessment concerning wildfires or other hazards and help better understand how local perceptions might influence residents' ongoing attitudes toward fire risk or mitigation efforts. The study presented here explored local perceptions of impact from the 2012 Dahl fire near Roundup, MT. The Dahl Fire burned 73 permanent structures, 150 outbuilding and 22,000 acres of predominantly private lands in the rural Bull Mountains. Members of the project team interviewed approximately 50 stakeholders impacted by or involved in the management for the Dahl Fire. Interviews took place in the summer of 2013 and included a variety of residents, emergency personnel, firefighters, local community officials and land management professionals. Results suggest that residents considered the Dahl fire especially impactful given the number of private residences and structures that were burned and the number of people displaced or disrupted by the event (either directly, through efforts to help those affected, or through indirect impacts to community function). The extremity of the firefighting conditions (e.g. wind, relative humidity, terrain), the rapidity of fire spread through populated areas and the damages sustained given previous fires in the area all surprised stakeholders and contributed to their perceptions of impact severity. Conflicts over access to properties during and immediately following the fire, and the variable perception that personal wildfire mitigations did little to reduce damages from the

    Full Text Available The purpose of this study is to determine which AMT has the greatest perceived impact on producer’s value and to identify which AMTs has been most successfully employed. The study population consists of senior manufacturing executives in electrical and electronic firms located in the northern region of Malaysia. The study addresses the senior manufacturing executives’ perceptions on how well specific AMTs have achieved the expectation of the firms implementing them. They are selected as respondents because of their understanding of the technology and their effects, and because as top manufacturing decision makers, their opinions are likely to shape the future technology of the organization. This study found that the type of AMT that perceived the greatest impact on producer’s value is Flexible Manufacturing System, due to its high effects on two dimensions of producer’s value: quality and cost while Just-in-Time is found to be the most successfully employed AMT among respondents. The findings of this study are significant as they contribute to the AMT literature especially in the context of Electrical and Electronic firms.

    Full Text Available With social media user numbers reaching billions, firms seek to partake in the benefits of investing into social media activities. Existing literature, however, provides little insight as to whether investment in social media adds value for corporations. In particular, it remains difficult to quantify the financial benefits for firms from social media activities. Prior research found uncertainty for small and large firms on whether value is derived from the information present on social media and the access to the large number of users. Based on a sample of 74 listed Australian firms for an observation period of 30 days of June 2016, this study examines the relationship between the firmrs social media activities on Facebook, LinkedIn and Twitter and corporate value. The results show that a firmrs social media presence on LinkedIn has a significant effect on the share return of firms, while a social media presence on Facebook and Twitter did not provide statistically significant results. Interestingly, the study also found that there is a difference between B2B and B2C firms, confirming a significant impact between for B2C firms on LinkedIn and share returns. The findings are useful for corporate managers and social media activists trying to understand the financial impacts of social media on corporate value.

    Full Text Available The authors conducted a sociological analysis of the spiritual and moral values of the youth and their impact on the civil culture, which largely determines the forms of individual and group social activity and the functioning of social institutions. The implementation of the key function of values, i.e. the achievement of material goods and the spiritual development, to a certain extent, will allow to overcome the cultural gap between elites and common citizens, which is considered one of the main reasons for the failure of reforms in Russia. The study of transformation processes determined great interest in the social potential of the youth as a subject of social reproduction, and the civil culture is a key factor and element of modernization for it changes and activates value orientations of the younger generations and leads to the qualitative transformations of all spheres of society. The article is based on the empirical data of a number of sociological surveys conducted in 2016 in five cities of the south of the Tyumen Region. The empirical data prove that there is an obvious emerging shift from paternalistic expectations, passivity and low estimates of the future to the rationality, individualization and self-reliance. The authors emphasize the influence of mass media as one of the factors of the civil culture formation, which is evident in the impact of media on the moral and spiritual values of the younger generations.

  9. Moment Magnitudes and Local Magnitudes for Small Earthquakes: Implications for Ground-Motion Prediction and b-values

    We illustrate two essential consequences of the systematic difference between moment magnitude and local magnitude for small earthquakes, illuminating the underlying earthquake physics. Moment magnitude, M 2/3 log M0, is uniformly valid for all earthquake sizes [Hanks and Kanamori, 1979]. However, the relationship between local magnitude ML and moment is itself magnitude dependent. For moderate events, 3> fmax. Just as importantly, if this relation is overlooked, prediction of large-magnitude ground motion from small earthquakes will be misguided. We also consider the effect of this magnitude scale difference on b-value. The oft-cited b-value of 1 should hold for small magnitudes, given M. Use of ML necessitates b=2/3 for the same data set; use of mixed, or unknown, magnitudes complicates the matter further. This is of particular import when estimating the rate of large earthquakes when one has limited data on their recurrence, as is the case for induced earthquakes in the central US.

    Illuminant direction estimation is an important research issue in the field of image processing. Due to low cost for getting texture information from a single image, it is worthwhile to estimate illuminant direction by employing scenario texture information. This paper proposes a novel computation method to estimate illuminant direction on both color outdoor images and the extended Yale face database B. In our paper, the luminance component is separated from the resized YCbCr image and its edges are detected with the Canny edge detector. Then, we divide the binary edge image into 16 local regions and calculate the edge level percentage in each of them. Afterward, we use the edge level percentage to analyze the complexity of each local region included in the luminance component. Finally, according to the error function between the measured intensity and the calculated intensity, and the constraint function for an infinite light source model, we calculate the illuminant directions of the luminance component's three local regions, which meet the requirements of lower complexity and larger average gray value, and synthesize them as the final illuminant direction. Unlike previous works, the proposed method requires neither all of the information of the image nor the texture that is included in the training set. Experimental results show that the proposed method works better at the correct rate and execution time than the existing ones.

    Full Text Available Increasing evidence associates excess refined sugar intakes with obesity, Type 2 diabetes and heart disease. Worryingly, the estimated volume of sugary drinks purchased in the UK has more than doubled between 1975 and 2007, from 510 ml to 1140 ml per person per week. We aimed to estimate the potential impact of a duty on sugar sweetened beverages (SSBs at a local level in England, hypothesising that a duty could reduce obesity and related diseases.We modelled the potential impact of a 20% sugary drinks duty on local authorities in England between 2010 and 2030. We synthesised data obtained from the British National Diet and Nutrition Survey (NDNS, drinks manufacturers, Office for National Statistics, and from previous studies. This produced a modelled population of 41 million adults in 326 lower tier local authorities in England. This analysis suggests that a 20% SSB duty could result in approximately 2,400 fewer diabetes cases, 1,700 fewer stroke and coronary heart disease cases, 400 fewer cancer cases, and gain some 41,000 Quality Adjusted Life Years (QALYs per year across England. The duty might have the biggest impact in urban areas with young populations.This study adds to the growing body of evidence suggesting health benefits for a duty on sugary drinks. It might also usefully provide results at an area level to inform local price interventions in England.

    The El Niño-Southern Oscillation (ENSO) and local temperature are important drivers of extreme precipitation. Understanding the impact of ENSO and temperature on the risk of extreme precipitation over global land will provide a foundation for risk assessment and climate-adaptive design of infrastructure in a changing climate. In this study, nonstationary generalized extreme value distributions were used to model extreme precipitation over global land for the period 1979-2015, with ENSO indicator and temperature as covariates. Risk factors were estimated to quantify the contrast between the influence of different ENSO phases and temperature. The results show that extreme precipitation is dominated by ENSO over 22% of global land and by temperature over 26% of global land. With a warming climate, the risk of high-intensity daily extreme precipitation increases at high latitudes but decreases in tropical regions. For ENSO, large parts of North America, southern South America, and southeastern and northeastern China are shown to suffer greater risk in El Niño years, with more than double the chance of intense extreme precipitation in El Niño years compared with La Niña years. Moreover, regions with more intense precipitation are more sensitive to ENSO. Global climate models were used to investigate the changing relationship between extreme precipitation and the covariates. The risk of extreme, high-intensity precipitation increases across high latitudes of the Northern Hemisphere but decreases in middle and lower latitudes under a warming climate scenario, and will likely trigger increases in severe flooding and droughts across the globe. However, there is some uncertainties associated with the influence of ENSO on predictions of future extreme precipitation, with the spatial extent and risk varying among the different models.

    The identification and characterization of chemicals that possess skin-sensitizing potential are typically performed using predictive tests. However, human exposure to skin-sensitizing chemicals often occurs via a matrix (vehicle) that differs from that used in these tests. It is thus important to account for the potential impact of vehicle differences when undertaking quantitative risk assessment for skin sensitization. This is achieved through the application of a specific sensitization assessment factor (SAF), scaled between 1 and 10, when identifying an acceptable exposure level. The objective of the analysis described herein is to determine the impact of vehicle differences on local lymph node assay (LLNA) EC3 values (concentrations of test chemical required to provoke a 3-fold increase in lymph node cell proliferation). Initially, the inherent variability of the LLNA was investigated by examining the reproducibility of EC3 values for 14 chemicals that have been tested more than once in the same vehicle (4:1 acetone:olive oil, AOO). This analysis reveals that the variability in EC3 value for these chemicals following multiple assessments is LLNA using at least 2 of 15 different vehicles. These data demonstrate that often the variability in EC3 values observed for a given chemical in different vehicles is no greater than the 5-fold inherent variability observed when assessing a chemical in the same vehicle on multiple occasions. However, there are examples where EC3 values for a chemical differ by a factor of more than 10 between different vehicles. These observations were often associated with an apparent underestimation of potency (higher EC3 values) with predominantly aqueous vehicles or propylene glycol. These data underscore the need to consider vehicle effects in the context of skin-sensitization risk assessments.

    Heavy use of insecticides considered as one of common practice at local farming systems. Even though many Indonesian researchers had stated the possible detrimental effect of insecticide on agriculture environment and biodiversity, researches on this subject had been neglected. Therefore, our purpose in this research is observing the impact of insecticides usage by farmer to non target organisme like local honey bee (Apis cerana indica), which commonly kept in area near agriculture system. This research consisted of field observations out at Ciburial, Dago Pakar, Bandung and laboratory tests at School of Life Sciences and Technology, Institut Teknologi Bandung. The field observations recorded visited agriculture corps and types of pollen carried by bees to the nest while laboratory test recorderd the effect of common insecticide to mortality and behavior of honey bees. Three types of insecticides used in this research were insecticides A with active agent Chlorantraniliprol 50 g/l, insecticide B with active agent Profenofos 500 g/l, and insecticides C with active agent Chlorantraniliprol 100 g/l and λ-cyhalotrin 50g/l. The results show that during one week visit, wild flower, Wedelia montana, visited by most honey bees with average visit 60 honey bees followed by corn, Zea mays, with 21 honey bees. The most pollen carried by foragers was Wedelia montana, Calliandra callothyrsus, and Zea mays. Preference test show that honeybees tend move to flowers without insecticides as the preference to insecticides A was 12.5%, insecticides B was 0%, and insecticides was C 4.2%. Mortality test showed that insecticides A has LD50 value 0.01 μg/μl, insecticide B 0.31 μg/μl, and insecticides C 0.09 μg/μl which much lower than suggested dosage recommended by insecticides producer. This research conclude that the use of insecticide could lower the pollination service provide by honey bee due to low visitation rate to flowers and mortality of foraging bees.

    Full Text Available Space as a resource is intensively used both by the tourism and the local community. Therefore the state of the tourism development must be measured trough time, along with attitudes of local population, to determine the impacts and the pressure that can continues tourism development cause. In the 1990s, tourism becomes the motor of the development of Croatia, which has resulted in continues increase of the number of tourist beds. On the other hand population of the Croatia is experiencing the demographic extinction. To explain pressures of the tourism development on the decreasing community, tourism function index was used in comparison with the research of the attitudes of local population considering tourism impacts. The main objective of this paper is to determine the correlation between the increase in the number of tourists and changes in the life of local population, which arises from the tourism activities in destinations, as well as from the ratio of the number of residents and tourists. The attitudes analysis has shown high level of the negative impacts of tourism in seven Adriatic counties, while in continental parts of Croatia tourism is seen as an activity with mostly positive effects. Still tourism has generally positive impact on the destination and is seen as desirable activity, even in areas with relatively high tourism function index. Accordingly, to enhance the positive impacts it is essential to diminish extremely big differences in tourism development between too developed coastal areas and mainly neglected continental part of the country and to reduce seasonality of tourism, trough sustainable management and diversification of tourism offer in accordance with spatial disparities.

    Highlights: • Market value of offshore wind based on feed-in and weather data is assessed. • Merit order effect caused by wind energy is simulated for 2006–2014. • Results indicate same impact of on- and offshore wind on market price and value. • Steadier wind resource offshore imposes less variability on market price. • Characteristic of variable wind feed-in cannot be blamed for price deterioration. - Abstract: Although the expansion of offshore wind has recently increased in Germany, as in other countries, it is still forced to defend its role in long-term energy policy plans, particularly against its onshore counterpart, to secure future expansion targets and financial support. The objective of this article is to investigate the economic effects of offshore wind on the electricity spot market and thus open up another perspective that has not been part of the debate about offshore vs. onshore wind thus far. A comprehensive assessment based on a large amount of market, feed-in and weather data in Germany revealed that the market value of offshore wind is generally higher than that of onshore wind. Simulating the merit order effect on the German day-ahead electricity market for the short term and long term in the years 2006–2014 aimed to identify the reason for this observation and show whether it is also an indication of a lower impact on the electricity spot market due to a steadier wind resource prevailing offshore. Although the results suggest no difference regarding the impact on market price and value, they indeed reveal that offshore wind imposes less variability on the spot market price than onshore wind. In addition, the long-term simulation proved that the ongoing price deterioration cannot be blamed on the characteristic of variable wind production

    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.

    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

    There are multiple ways for a homeowner to obtain the electricity generating and savings benefits offered by a photovoltaic (PV) system. These include purchasing a PV system through various financing mechanisms, or by leasing the PV system from a third party with multiple options that may include purchase, lease renewal or PV system removal. The different ownership options available to homeowners presents a challenge to appraisal and real estate professionals during a home sale or refinance in terms of how to develop a value that is reflective of the PV systems operational characteristics, local market conditions, and lender and underwriter requirements. This paper presents these many PV system ownership options with a discussion of what considerations an appraiser must make when developing the contributory value of a PV system to a residential property.

    2013-09-01

    Full Text Available This study builds on the theory that transformational leadership impacts perceptions of leader-follower value congruence. The study examines intrinsic, altruistic, and social work values in a sample of 150 workers in the United States. The hypotheses tested that different levels of transformational leadership, as perceived by followers, are positively related to follower perceptions of leader-follower intrinsic, altruistic, and social work value congruence. Utilizing hierarchical multiple regression, the findings indicate that  levels of perceived transformational leadership are positively related to higher levels of perceived leader-follower intrinsic, altruistic, and social work value congruency. This study used four different measurement tools to test these hypotheses and controlled for task-oriented behaviors, tenure with supervisor as well as race, gender, and age similarity with supervisor. The findings suggest that organizations involved in a restructuring or reorganization due to either internal or external circumstances should emphasize developing leaders’ transformational leadership behaviors in order to capture benefits related to value congruency.

    Highlights: • A stochastic mixed integer linear model is proposed to maximize the profit and the future water value. • Conditional Value at Risk (CVaR) is used for risk-hedging. • The offer strategies analyzed are single and separate, with and without a physical connection. • The effect of considering the future water value of the reservoirs is studied for several time horizons. - Abstract: A coordinated offering strategy between a wind farm and a reversible hydro plant can reduce wind power imbalances, improving the system efficiency whilst decreasing the total imbalances. A stochastic mixed integer linear model is proposed to maximize the profit and the future water value FWV of the system using Conditional Value at Risk (CVaR) for risk-hedging. The offer strategies analyzed are: (i) single wind-reversible hydro offer with a physical connection between wind and hydro units to store spare wind energy, and (ii) separate wind and reversible hydro offers without a physical connection between them. The effect of considering the FWV of the reservoirs is studied for several time horizons: one week (168 h) and one month (720 h) using an illustrative case study.

    To evaluate the feasibility and value of diffusion kurtosis (DK) imaging in assessing treatment response to neoadjuvant chemoradiotherapy (CRT) in patients with locally advanced rectal cancer (LARC). Forty-one patients were included. All patients underwent pre- and post-CRT DCE-MRI on a 3.0-Tesla MRI scanner. Imaging indices (D{sub app}, K{sub app} and ADC values) were measured. Change value (∇X) and change ratio (r ∇X) were calculated. Pathological tumour regression grade scores (Mandard) were the standard reference (good responders: pTRG 1-2; poor responders: pTRG 3-5). Diagnostic performance was compared using ROC analysis. For the pre-CRT measurements, pre-D{sub app-10th} was significantly lower in the good responder group than that of the poor responder group (p = 0.036). For assessing treatment response to neoadjuvant CRT, pre-D{sub app-10th} resulted in AUCs of 0.753 (p = 0.036) with a sensitivity of 66.67 % and a specificity of 77.78 %. The r ∇D{sub app} had a relatively high AUC (0.859) and high sensitivity (100 %) compared with other image indices. DKI is feasible for selecting good responders for neoadjuvant CRT for LARC.

    The purpose of this study was to develop a new way to localize the impacted canines from three dimensions and to investigate the root resorption of the adjacent teeth by using cone beam computed tomography (CBCT). Forty-six patients undergoing orthodontic treatments and having impacted canines in Tongji Hospital were examined. The images of CBCT scans were obtained from KaVo 3D exam vision. Angular and linear measurements of the cusp tip and root apex according to the three planes (mid-sagittal, occlusal and frontal) have been taken using the cephalometric tool of the InVivo Dental Anatomage Version 5.1.10. The measurements of the angular and linear coordinates of the maxillary and mandibular canines were obtained. Using this technique the operators could envision the location of the impacted canine according to the three clinical planes. Adjacent teeth root resorption of 28.26 % was in the upper lateral incisors while 17.39% in upper central incisors, but no lower root resorption was found in our samples. Accurate and reliable localization of the impacted canines could be obtained from the novel analysis system, which offers a better surgical and orthodontic treatment for the patients with impacted canines.

  8. State and local fiscal impacts associated with nuclear energy centers: some initial considerations

    1976-04-01

    The concept of the nuclear energy center is designed to consolidate a number of electrical power reactors and/or related fuel cycle activities on a single site. Such a siting strategy would concentrate a great deal of economic activity in one area and, as a consequence, generate significant impacts on state and local governments by increasing tax bases and public service demands and by altering intergovernmental fiscal relations. This study was designed to place rough empirical measures on relevant impact variables and to highlight areas for which a need for further research was indicated.

  9. Local content requirements and the impact on the South African renewable energy sector: A survey-based analysis

    Full Text Available Background: Economies aim to grow over time, which usually implies the need for increased energy availability. Governments can use their procurement of energy to increase benefits in their economies via certain policy tools. One such tool is local content requirements (LCRs, where the purchase of goods prescribes that a certain value has to be sourced locally. The argument for this tool is that spending is localised and manufacturing, as well as job creation, can be stimulated because industry will need to establish in the host economy. However, this practice is distortionary in effect and does not create a fair playing ground for global trade. Furthermore, if the local content definition is weak, or open to manipulation, the goals of such a policy may not be achieved at all. Aim: The objective of this study was to determine how LCRs would ultimately impact on the overall procurement programme. Setting: This study took place as South Africa commenced with large scale development of the renewable energy sector. This was largely achieved via the State run Renewable Energy Independent Power Producer Procurement Programme (REIPPPP. Method: This study utilised opinion-based surveys to look into the LCRs of South Africa’s REIPPPP and measure the impact of this policy on the renewable energy sector in general. The mixed method approach was utilised to analyse qualitative and quantitative data and this was then triangulated with an international peer group to arrive at certain conclusions. The Delphi Technique was then employed to achieve population consensus on the findings. Results and conclusion: It was found that, in order to implement a policy such as local content without any negative welfare effects, the host economy had to show certain pre-existing conditions. Because South Africa does not hold all supportive pre-conditions, the impact and effect of LCRs have not been optimal, and it has not been found to be a sustainable mechanism to

    Worker training is a core component of the OSHA Hazardous Waste Operations and Emergency Response (HAZWOPER) standard, but few studies have considered what motivates managers to provide HAZWOPER training to employees or what they value in that training. In 2012, four university-based programs conducted an exploratory survey of managers who sent employees to HAZWOPER courses. Results from 109 respondents were analyzed. Forty-two percent of respondents cited regulations as the most important reason to provide HAZWOPER training; many indicated they would provide less training if there were no standard in place. Three-quarters (74%) reported training had improved workplace conditions. Fewer than half said they were likely to involve trained employees in aspects of the organization's H&S program. Compliance with regulatory requirements is an important factor shaping managers' training delivery decisions. Managers recognize positive impacts of training. These impacts could be enhanced by further leveraging employee H&S knowledge and skills. © 2015 Wiley Periodicals, Inc.

  12. A Comprehensive Review of the Evidence of the Impact of Surface Water Quality on Property Values

    Directory of Open Access Journals (Sweden)

    2018-02-01

    Full Text Available The desirability of living on or close to water is reflected in sometimes substantial property price premiums. Water quality has an important influence on property prices, since it impacts a water body’s appearance, capacity to support wildlife, and recreational potential. As water quality continues to be altered by human use and activity, and in light of new threats posed by projected climate and associated environmental change, understanding the impact of changing quality on property prices, and the associated property tax base, is paramount. This paper reviews the body of evidence on this topic to date. Of the 43 distinct studies represented in the 48 publications reviewed, the expected, statistically significant relationship between water quality and property price was demonstrated in at least one of the models developed in all but two studies. As a whole, they provide convincing evidence that clean water has a positive effect on property values.

    Assessing the sustainability of International policy or urban development requires consideration of the impacts of these decisions on Ecosystem Services, or the values that humans receive from the ecosystem, including market-land price, environmental, and human well-being values. Hedonic modeling helps to identify the market land price, considering the price is determined by multiple factors affecting it. In U.S. portions of the bi-national Santa Cruz Watershed (SCW), situated at the Arizona-Sonora International border, natural amenities like the riparian corridor and green space have been documented as positive amenities that boost local real estate.

    Renewable energy sources (RES) have a large potential to contribute to the sustainable development (SD) of specific territories by providing them with a wide variety of socioeconomic and environmental benefits. However, the existing literature has put much emphasis on the environmental benefits (including the reduction of global and local pollutants), while socioeconomic impacts have not received a comparable attention. These include diversification of energy supply, enhanced regional and rural development opportunities, creation of a domestic industry and employment opportunities. With the exception of the diversification and security of energy supply, these benefits have usually been mentioned, but their analysis has been too general (i.e., mostly at the national level) and a focus on the regional and, even more so, the local level, has been lacking. At most, studies provide scattered evidence of some of those regional and local benefits, but without an integrated conceptual framework to analyse them. This paper tries to make a contribution in this regard by developing an integrated theoretical framework which allows a comprehensive analysis of the impact of renewable energy on local sustainability and which can be empirically applied to identify these benefits in different territories.

  17. Adaptability and suitability of local cattle breeds in Egypt: Farmers and actors’ perceptions and practices of the cattle value chain

    Directory of Open Access Journals (Sweden)

    M. A. Osman

    2017-02-01

    Full Text Available Egypt, where the mean temperature is expected to increase by 1−1.5°C over the next two decades, is particularly concerned with climate change in the Mediterranean. Most of the research works on adaptive animal traits have focused on sheep and goats in non-irrigated areas, with little interest in livestock systems in irrigated areas. However, meat and dairy products in Egypt are mainly supplied by large ruminants − cattle and buffaloes. In addition, research on genetic improvement to increase production has neglected local cattle breeds such as the Baladi, which appears to be endangered. Based on individual and collective interviews conducted in two governorates of Egypt, this study aimed to describe the situation of this local breed based on the perceptions and practices of the actors in the sector (including farmers, traders and service suppliers, and to draw perspectives for its future. From the interviews, the Baladi appeared adapted and more resistant to harsh conditions, especially to extreme warm temperatures, feed shortage periods, and some diseases, in particular foot-and-mouth disease. However, there is no organization or collective action to preserve or promote this breed because of its low level of dairy production, although its meat is highly valued in rural areas and could be the source of a potential niche market.

Animals were slaughtered with the body weight ca. 95 kg. The aim of research was to determine pH value of loin meat tissue (Longissimus dorsi of right half-carcass in 45 minutes, 2, 3, 4, 5, 6 hours and 24 hours after slaughter. Results were statistically elaborated using one-way variance analysis. Longissimus dorsi muscle pH values measured 45 minutes after slaughter in case of all groups of pigs were in range from 6.34 up to 6.47, what shows good meat quality. The lowest pH1 (measured 45 minutes after slaughter had meat of fatteners where addition of 2 % sunflower oil was given into fodder and the highest value of this trait was in group of individuals where also was given sunflower oil in 1 % amount. Statistical significant differences in pH value measured in different time after slaughter i.e. after 45 minutes, 2, 3, 4, 6 and 24 hours between tested groups of pigs were not stated. The exception is the result of pH measurement 5 hours after slaughter. Statistical significant differences were between group of pigs getting 0.5 % addition of conjugated linoleic acid characterized by the highest pH value of meat and group of animals fed the fodder with 1 % addition of conjugated linoleic acid (P≤0.01. On the basis of the results obtained in presented paper may be stated that feeding pigs with addition of conjugated linoleic acid in amounts 0.5; 1.0 and 2.0 % did not impact negatively on meat quality defined by pH value.

    2016-12-01

    Full Text Available Much has been written about service quality impacts on customer satisfaction. However, little research on this perspective has been carried out in military settings. The aim of this study is to examine the relationship between service quality and customer satisfaction, and moderating effects of perceived value in military medical centre. A survey method was employed and data was collected from customers at medical centers under the administration of Malaysian army organization. Analysis was performed using SmartPLS path model analysis. The results show two important findings: first, the interaction between four service quality components (i.e., tangible, reliability, responsiveness and assurance and customers’ perceived value were significantly correlated with customer satisfaction. Second, the interaction between one service quality component (i.e., tangible were not significantly correlated with customer satisfaction. In overall, this result confirms that effect of tangible, reliability, responsiveness and assurance on customer satisfaction has been moderated by customers’ perceived value. Conversely, effect empathy on customer satisfaction has not been moderated by customers’ perceived value. Further, this study offers discussion, implications and conclusion.

    The impact of the accumulated experience of the capsule endoscopy (CE) reader on the accuracy of this test is discussed. To determine whether the negative predictive value of CE findings changes along the learning curve. We reviewed the first 900 CE read by 3 gastroenterologists experienced in endoscopy over 8 years. These 900 CE were divided into 3 groups (300 CE each): group 1 consisted of the sum of the first 100 CE read by each of the 3 endoscopists; group 2, the sum of the second 100 and groups 3, the sum of the third 100. Patients with normal CE were monitored for at least 28 months to estimate the negative predictive value. A total of 54 (18%) CE in group 1, 58 (19.3%) in group 2 and 47 (15.6%) in group 3 were normal, although only 34 patients in group 1, 38 in group 2 and 36 in group 3 with normal CE completed follow up and were eventually studied. The negative predictive value was 88.2% in group 1, 89.5% in group 2 and 97% in group 3 (P>.05). The negative predictive value tended to increase, but remained high and did not change significantly after the first 100 when readers are experienced in conventional endoscopy and have preliminary specific training.

  3. Aristotle: A performance Impact Indicator for the OpenCL Kernels Using Local Memory

    2014-01-01

    Full Text Available Due to the increasing complexity of multi/many-core architectures (with their mix of caches and scratch-pad memories and applications (with different memory access patterns, the performance of many workloads becomes increasingly variable. In this work, we address one of the main causes for this performance variability: the efficiency of the memory system. Specifically, based on an empirical evaluation driven by memory access patterns, we qualify and partially quantify the performance impact of using local memory in multi/many-core processors. To do so, we systematically describe memory access patterns (MAPs in an application-agnostic manner. Next, for each identified MAP, we use OpenCL (for portability reasons to generate two microbenchmarks: a “naive” version (without local memory and “an optimized” version (using local memory. We then evaluate both of them on typically used multi-core and many-core platforms, and we log their performance. What we eventually obtain is a local memory performance database, indexed by various MAPs and platforms. Further, we propose a set of composing rules for multiple MAPs. Thus, we can get an indicator of whether using local memory is beneficial in the presence of multiple memory access patterns. This indication can be used to either avoid the hassle of implementing optimizations with too little gain or, alternatively, give a rough prediction of the performance gain.

    The platelet-rich plasma (PRP) is an autologous biotherapy commonly used for its healing properties. Once activated, platelets released a real "cocktail" of growth factor and cytokines implied in numerous regenerative processes. However the impact of medical practices associated to PRP therapeutic use on platelets functionality remains poorly known. we evaluated the in vitro effects of two commonly used local anesthetics (Xylocaine(*) and Naropin(*)) on PRP functionality. We also investigated the quantity and quality of PRP that passed through the smallest gauge needle commercialized. PRP from 9 healthy volunteers were prepared using our previously described home made purification protocol. Platelet aggregation capacity was evaluated by aggregometry assays and the growth factor release was determined by ELISA after platelet activation. We also evaluated the platelet activation status, reactivity and stability of platelets by flow cytometry using the P-selectin expression marker. the association of local anaesthetics with PRP injections resulted in a significant decrease of platelets functionality, assessed by their capacity of aggregating. Local anaesthetics did not interfere with the growth factor release. The different needle sizes and calibres tested for PRP injections did not influence the platelet functionality. the use of local anaesthetics to prevent pain during PRP injections could compromise the therapeutic potential of PRP. These results suggest using carefully local anaesthetics or limiting their use as often is possible. To minimize injection pain, we recommend using 30 G needles. These data will lead to clinical recommendations for painless and controlled PRP injections.

    Purpose: The aim of this population-based study was to examine the impact of postmastectomy radiotherapy on the risk of local recurrence in patients with invasive lobular breast cancer (ILC). Methods: The population-based Eindhoven Cancer Registry was used to select all patients with ILC, who underwent mastectomy in five general hospitals in the southern part of Netherlands between 1995 and 2002. Of the 499 patients 383 patients fulfilled the eligibility criteria. Of these patients, 170 (44.4%) had received postmastectomy radiotherapy. The median follow-up was 7.2 years. Fourteen patients (3.7%) were lost to follow-up. Results: During follow-up 22 patients developed a local recurrence, of whom 4 had received postmastectomy radiotherapy. The 5-year actuarial risk of local recurrence was 2.1% for the patients with and 8.7% for the patients without postmastectomy radiotherapy. After adjustment for age at diagnosis, tumour stage and adjuvant systemic treatment, the patients who underwent postmastectomy radiotherapy were found to have a more than 3 times lower risk of local recurrence compared to the patients without (Hazard Ratio 0.30; 95% Confidence Interval: 0.10-0.89). Conclusion: Local control is excellent for patients with ILC who undergo postmastectomy radiotherapy and significantly better than for patients not receiving radiotherapy.

Meanwhile, the local inflammation, which is characterized by dense intratumoral immune infiltrate, is a favorable predictor of survival outcome. Purpose: To evaluate the role of systemic and local inflammation in predicting outcome in patients with laryngeal squamous cell carcinoma. Patients and methods: In this retrospective study, 120 patients who had undergone postoperative radiotherapy were enrolled. Neutrophil-to-lymphocyte ratio (NLR and platelet-to-lymphocyte ratio (PLR, as calculated from pretreatment whole blood counts, were used to indicate systemic inflammation. The optimal cutoff values of NLR and PLR were determined using receiver operating characteristic curve analysis. Tumor infiltrating lymphocytes (TILs density, as assessed by pathologist review of hematoxylin and eosin-stained slides, was used to represent local inflammation. Overall survival (OS and recurrence-free survival (RFS were assessed using the Kaplan–Meier method and multivariate Cox regression analysis. Results: The best cutoff was 2.79 for NLR and 112 for PLR. Kaplan–Meier analysis revealed that high NLR, high PLR, and low TILs density were significantly correlated with inferior OS and RFS, respectively (all P<0.05. The Cox proportional multivariate hazard model showed that a high pretreatment PLR and a low TILs density were both independently correlated with poor OS and RFS, respectively (all P<0.05.

  8. Butterfly effect: understanding and mitigating the local consequences of climate change impacts

    Lorenz, Donna

    2007-01-01

    Full text: The Butterfly Effect is the notion that tiny differences in initial conditions are amplified in the evolution of a dynamic system and directly affect the eventual outcome. In 1963 mathematician and meteorologist Edward Lorenz proposed that the flapping of a butterfly's wing would cause a disturbance that becomes exponentially amplified so as to eventually affect large-scale atmospheric motion. This was to illustrate the 'sensitive dependence on initial conditions'; sensitivity also true in affecting the extent of damages experienced as a result of climate change. In a climate change context, The Butterfly Effect suggests the local consequences of climate change impacts will depend on their interaction with the economic, environmental, institutional, technological and demographic attributes unique to a city or region. It is this mix of factors that will determine the extent, both positively and negatively, to which climate change will be experienced locally. For a truly effective climate change response, it is imperative that regional risk assessments and adaptation strategies take into account not only the projected impacts but the full range of flow-on implications of those impacts and their sensitivity factors. Understanding of the sensitivity factors that will amplify or mitigate climate change impacts and implications enables government and business leaders to calculate the likely extent of localised damages if no adaptation is undertaken. This allows industries and communities to evaluate the likely significance of a particular impact and to consider how to adjust or counter the sensitivity factor to build resilience and reduce vulnerability. Thus, it also assists in the local prioritisation of issues and responses. Such a strategic response can also mean the required adaptation measures may be less extensive and thereby require less cost and time to implement. This paper discusses the flow-on implications of Australia's projected climate change

    Farmers can use their own agricultural biomass residues for heat production in small-scale systems, enabling synergies between the district heating (DH) sector and agriculture. The barriers to entry into the Swedish heat market were extremely high as long as heat distribution were considered natural monopoly, but were recently lowered due to the introduction of a regulated third party access (TPA) system in the DH sector. This study assesses the potential impact on greenhouse gas emissions and cost-based heat price in the DH sector when farmers vertically integrate into the heat supply chain and introduce more local and agricultural crops and residues into the fuel mix. Four scenarios with various degree of farmer integration, were assessed using life cycle assessment (LCA) methodology, and by analysis of the heat production costs. The results show that full integration of local farm and forest owners in the value chain can reduce greenhouse gas emissions and lower production costs/heat price, if there is an incentive to utilise local and agricultural fuels. The results imply that farmer participation in the DH sector should be encouraged by e.g. EU rural development programmes. - Highlights: • Five DH production systems based on different fuels and ownership were analysed. • Lower GHG emissions were obtained when farmers integrate fully into the DH chain. • Lower heat price was obtained by full vertical integration of farmers. • Salix and straw-based production resulted in the lowest GHG and heat price

    Highlights: → Market driven reasons can strengthen implementation of energy policies in buildings. → Methods that quantify the added value due to energy performance are developed. → Recommendations on how they can be incorporated in the financial analysis are presented. → Case studies on some existing condominiums from Romania are analyzed. → The market sensitivity to energy efficiency measures is also in the focus. -- Abstract: A main objective of energy policies is to make all levels of the society, from governments to citizen, interested in increasing the energy efficiency of buildings. One of the most important barriers in implementation of energy policies is that the cost of potential energy savings, typically considered being the only financial benefit, does not sufficiently motivate investments. The target is therefore to identify further possible drivers pushing positive reaction according to energy saving action. The paper discusses whether a market-based instrument, capturing the increase of the economic value of energy efficient buildings, can be also used. Methods that quantify the added value due to energy performance, including recommendations on how they can be incorporated in the financial analysis of investments in weatherization, are developed. By applying the proposed methods, the payback period of investments in energy efficiency measures depends on two factors: potential energy savings and the added value to the property. Case studies on some existing condominiums from Romania are analyzed and provide evidence to the research question. The market sensitivity to energy efficiency measures, the possibility of an intangible added value as well as the impact to financial investment decisions is subsequently in the focus.

    Most reviews concerning the impact of climate change on coral reefs discuss independent effects of warming or ocean acidification. However, the interactions between these, and between these and direct local stressors are less well addressed. This review underlines that coral bleaching, acidification, and diseases are expected to interact synergistically, and will negatively influence survival, growth, reproduction, larval development, settlement, and post-settlement development of corals. Interactions with local stress factors such as pollution, sedimentation, and overfishing are further expected to compound effects of climate change. Reduced coral cover and species composition following coral bleaching events affect coral reef fish community structure, with variable outcomes depending on their habitat dependence and trophic specialisation. Ocean acidification itself impacts fish mainly indirectly through disruption of predation- and habitat-associated behavior changes. Zooxanthellate octocorals on reefs are often overlooked but are substantial occupiers of space; these also are highly susceptible to bleaching but because they tend to be more heterotrophic, climate change impacts mainly manifest in terms of changes in species composition and population structure. Non-calcifying macroalgae are expected to respond positively to ocean acidification and promote microbe-induced coral mortality via the release of dissolved compounds, thus intensifying phase-shifts from coral to macroalgal domination. Adaptation of corals to these consequences of CO2 rise through increased tolerance of corals and successful mutualistic associations between corals and zooxanthellae is likely to be insufficient to match the rate and frequency of the projected changes. Impacts are interactive and magnified, and because there is a limited capacity for corals to adapt to climate change, global targets of carbon emission reductions are insufficient for coral reefs, so lower targets should be

    Biomass burning is a significant source of carbon monoxide and particulate matter, which is not only contribute to the local air pollution, but also regional air pollution. This study investigated the impacts of biomass burning emissions from Southeast Asia (SEA) as well as its contribution to the local air pollution in East and South China Sea, including Hong Kong and Taiwan. Three years (2012 - 2014) of the Hybrid Single Particle Lagrangian-Integrated Trajectory (HYSPLIT) with particles dispersion analyses using NCEP (Final) Operational Global Analysis data (FNL) data (2012 - 2014) were analyzed to track down all possible long-range transport from SEA with a sinking motion that worsened the surface air quality (tropospheric downwash from the free troposphere). The major sources of SEA biomass burning emissions were first identified using high fire emissions from the Global Fire Emission Database (GFED), followed by the HYSPLIT backward trajectory dispersion modeling analysis. The analyses were compared with the local observation data from Tai Mo Shan (1,000 msl) and Tap Mun (60 msl) in Hong Kong, as well as the data from Lulin mountain (2,600 msl) in Taiwan, to assess the possible impacts of SEA biomass burning on local air quality. The correlation between long-range transport events from the particles dispersion results and locally observed air quality data indicated that the background concentrations of ozone, PM2.5 and PM10 at the surface stations were enhanced by 12 μg/m3, 4 μg/m3 and 7 μg/m3, respectively, while the long-range transport contributed to enhancements of 4 μg/m3, 4 μg/m3 and 8 μg/m3 for O3, PM2.5 and PM10, respectively at the lower free atmosphere.

    Anthropogenic aerosols exert significant climate forcing, which increases with emissions following trends of growing population and industry. Globally, aerosols cause a net cooling, counteracting greenhouse gas warming; however, regional impacts vary since emissions are spatially and temporally heterogeneous. While European and North American emissions have decreased in recent decades, Asian, particularly East Asian, emissions continued to rise into the 21st century. In addition to links between Asian anthropogenic aerosols and significant local climate impacts - for example, changes to the Asian monsoon system - studies have also shown influences on remote climate. Sulfate aerosols are particularly important for East Asia, remaining at constant levels higher than column burdens of other aerosol species. If a concerted effort - as laid out by government policies aiming to improve air quality - is made, the effects of anthropogenic aerosols (due to their short atmospheric lifetime) could be quickly reversed. Thus, it is vital to understand the climate impact aerosols have had up to now to aid in determining what will happen in the future. We use transient climate modelling experiments with the Community Earth System Model to investigate the impacts of East Asian sulfate aerosols in the present day compared to 1950 (i.e. before rapid industrialisation in this region), focusing on dynamical mechanisms leading to the occurrence of such impacts, and how their influence can spread to remote regions. We find, in addition to significant monsoon impacts, noticeable shifts in large-scale circulation features such as the ITCZ and the Pacific Walker cell. Through diabatic heating responses, changes to upper-level atmospheric dynamics are evident, leading to downstream effects on surface climate - for example, surface cooling over Europe. Understanding of these impacts is vital when considering how the good intentions of air quality improvement might inadvertently have

    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.

    The use of locally produced forage (LPF) in cattle production has economic and environmental advantages over imported forage. The objective of this study was to characterize the nutritional value of LPF commonly used in Korea. Differences in ruminal fermentation characteristics were also examined for the LPF species commonly produced from two major production regions: Chungcheong and Jeolla. Ten LPF (five from each of the two regions) and six of the most widely used imported forages originating from North America were obtained at least three times throughout a year. Each forage species was pooled and analyzed for nutrient content using detailed chemical analysis. Ruminal fermentation characteristics were also determined by in vitro anaerobic incubations using strained rumen fluid for 0, 3, 6, 12, 24, and 48 h. At each incubation time, total gas, pH, ammonia, volatile fatty acid (VFA) concentrations, and neutral detergent fiber digestibility were measured. By fitting an exponential model, gas production kinetics were obtained. Significant differences were found in the non-fiber carbohydrate (NFC) content among the forage species and the regions (pruminal fermentation of LPF between the two regions and interactions between regions and forage species were also significant (pruminal fermentation was lower in the forages from Chungcheong than from Jeolla (p<0.01), and total VFA concentration was higher in Chungcheong than in Jeolla (p = 0.05). This implies that fermentation was more active with the forages from Chungcheong than from Jeolla. Analysis of gas production profiles showed the rate of fermentation differed among forage species (p<0.05). The results of the present study showed that the nutritional values of some LPF (i.e., corn silage and Italian ryegrass) are comparable to those of imported forages widely used in Korea. This study also indicated that the nutritional value of LPF differs by origin, as well as by forage species. Detailed analyses of nutrient

    A diagnostic survey and participatory rural appraisal were conducted to determine the potential feed value, mode of and constraints to the use of locally produced wet spent brewers' grains fed to dairy cattle. Structured questionnaire instruments, covering, household characteristics, dairy production, feeds and feeding and extension services were used. The survey was conducted by trained enumerators. The tools used in participatory rural appraisal were; semi-structured interview, ranking seasonal calendars labour profile and gender responsibilities.The main feed resources were Napier grass, green and dry maize stover, public land grasses and supplements consisting of Dairy meal, milling and agroindustrial by-products.Wet spent brewers' grain is one of the by-products.The main sources were Kenya Breweries Limited, Kuguru Food Processors and 'Busaa' dregs from the traditional brews. It was fed to dairy cows by (96.8%) of the households interviewed, either at milking in the mornings or evenings. Spent brewers grains was stored after collection from the sources by (87.2%) and (12.8%) of the households for one or more weeks respectively. Households interviewed perceived spent brewers grains to be comparable to available dairy meal and other energy feeds, and all the households feeding spent brewers grains reported that it increased milk yield in lactating cows. The farmers therefore, preferentially fed spent brewers grains to lactating and dry cows, heifers, calves and bulls respectively. However, only (1.7%)of the households interviewed received extension advice on the use of spent brewers' grains. The perception of the farmers/household was that spent brewers' grains is a valuable feed for dairy cattle and increased milk yield production, and maintained good body condition. However,limited information is available on the potential, mode of and constraints to the use of locally produced spent brewers' grains

    It is widely accepted that autochthonous cattle breeds can be important genetic resources for unforeseeable environmental conditions in the future. Apart from that, they often represent local culture and tradition and thus assist in the awareness of ethnic identity of a country. In Croatia, there are only three indigenous cattle breeds, Croatian Buša, Slavonian Syrmian Podolian and Istrian Cattle. All of them are threatened but specialized in a particular habitat and production system. We analysed 93 microsatellites in 51 animals of each breed to get thorough information about genetic diversity and population structure. We further set them within an existing frame of additional 16 breeds that have been genotyped for the same marker set and cover a geographical area from the domestication centre near Anatolia, through the Balkan and alpine regions, to the north-west of Europe. The cultural value was evaluated regarding the role in landscape, gastronomy, folklore and handicraft. The overall results recognize Croatian Buša being partly admixed but harbouring an enormous genetic diversity comparable with other traditional unselected Buša breeds in the Anatolian and Balkan areas. The Podolian cattle showed the lowest genetic diversity at the highest genetic distance to all remaining breeds but are playing an important role as part of the cultural landscape and thus contribute to the tourist industry. The genetic diversity of the Istrian cattle was found in the middle range of this study. It is already included in the tourist industry as a local food speciality. Current and future conservation strategies are discussed. © 2010 Blackwell Verlag GmbH.

    Purpose: To evaluate the prognostic value of triple-negative (TN) ER, PR, Her2/neu basal-like carcinoma of the breast, at the time of ipsilateral breast tumor recurrence (IBTR) after conservative surgery and radiation treatment (RT). Methods and Materials: A tissue microarray was constructed of 47 IBTR specimens of patients who experienced an IBTR after conservative surgery and RT that were processed and stained for ER, PR, and HER2/neu. Results: At a median post-recurrence follow-up of 7.5 years, the 5-year overall survival (OS) and disease metastasis-free survival (DMFS) after IBTR were 91.4% and 83.0%, respectively. Median time to tumor recurrence (TTR) and IBTR was shorter in the TN phenotype (3.88 vs. 5.00 years; p = 0.09). The TN tumors were not associated with size of local recurrence or recurrence elsewhere in the breast. Despite administration of standard chemotherapy at the time of IBTR, the 5-year DMFS and 5-year OS for the TN cohort were 48.6% and 72.7%, respectively. The 5-year DMFS was 48.6% for TN tumors and 90.8% for non-TN tumors (p < 0.01). By univariate analysis, significant factors associated with poor 5-year DMFS and OS after IBTR included: TN phenotype (p < 0.01), TTR 3 years or less (p < 0.01), local recurrence at or near the original tumor site (p = 0.08). In multivariate analysis, TN was a significant independent predictor of poorer 5-year DMFS (relative risk, 5.91; 95% confidence interval, 1.83-19.01; p < 0.01) after IBTR. Conclusions: Although patients experiencing an IBTR have a relatively favorable prognosis, those with IBTR events of the TN phenotype had a rather poor prognosis despite receiving standard chemotherapy. Strategies with novel systemic therapies to improve outcomes in patients experiencing IBTR of the TN phenotype are warranted

    The usefulness of MR imaging in the evaluation of the degree of soft tissue malignancy is widely discussed. The aim of this study was to analyse the diagnostic value of MR imaging in the evaluation of local progression of soft tissue tumours and to analyse the usefulness of MR imaging in the differential diagnosis (malignant versus benign lesions). One hundred and ten patients with soft tissue tumours were examined by MR imaging (60 men and 50 women, aged 16 to 84 years). MR imaging was carried out with an Elscint 2T or 0.5T unit. Surface coils (passive) or circular polarized coils (active) depending on the localisation of the lesions were used with field vision from 20x24 cm or 40x40 cm, matrices 200x256, 256x256, or 22x315, layer thickness from 3 to 10 mm, gap 20-30%. SE T1 sequences (TR = 500 - 800 ms, TE = 15 - 20 ms) and FSE T2 (Tr = 2000-4500 ms, TE = 96-104 ms) were routinely used in at least two planes: transverse, frontal or saggital, and SE T1 sequences were used after administration of gadolinium Gd-DTPA in 0.1 m - 0.2 mmol/kg body weigh doses. The tumour dimensions by MR imaging were compared with the results of histological examination of samples obtained during surgery (65 cases) - the statistical analysis was performed using Student's t-test, with statistically significant difference accepted at p = 0.05 or less. The borders of the lesions were assessed in the entire material and in the group of 65 patients treated surgically. The latter were compared with the results of histological examination after surgery, thus calculating MR sensitivity and specificity. Static imaging is a valuable diagnostic method for preoperative assesment of the local progression of soft tissue tumours, however it is not suitable for differentiating malignant lesions from benign according to tumour size, borders and local extent.

    Full Text Available This article examines the nature and degree of influence of service liberalization on the participation of the BRICS grouping of Brazil, Russia, India, China and South Africa in global value chains (GVCs. The inverse relationship between the barriers in infrastructure services and the degree of participation of countries in GVCs was determined using econometric analysis methods. Using data on the structure of trade in goods and services in terms of value added, the situation of developing countries was analyzed using the example of the BRICS in production and service GVCs. China and India are the most deeply integrated countries in the international production and service chains while Russia, Brazil and South Africa participate in the production value chains as suppliers of raw materials and intermediate goods with low added value. However, these countries have a significant potential to expand their participation in the system of international production by improving the infrastructure necessary for the operation of the GVC. This study of the experience of liberalization in certain service sectors in BRICS countries reveals the positive impact of reducing barriers in maritime, rail and air transportation sectors, as well as finance, for improving the quality and reducing the cost of services. The authors note that in many respects, these effects were the result not only of reducing barriers in services, but also the implementation of a set of measures aimed at increasing the investment attractiveness of countries. The article concludes that the liberalization of infrastructure services industries can become one of the tools for integrating BRICS countries into the GVC. However, this liberalization should be part of a broader development strategy that includes trade and investment policy measures aimed not only at increasing participation in global production, but also overall economic development of the country

    Full Text Available Purpose of this paper is to identify the tendency of shrimp value chain development and impact of its governance on the small scale shrimp farmers in Vietnam. Design/methodology/approach - Data from the shrimp farmers surveys in Mekong delta, Vietnam from 2008-2010 with the update information in 2014 were taken to analyse by the value chain analysis method. Findings – Traditional governance type of the shrimp value chain in the early state (before 2004 showed the different levels of coordination of farmers with collectors, among collectors, and collectors with processing plants. In this type of governance, trust and linkages are inextricably linked. However, they are not strong. The processing plants determine shrimp prices and quality requirement in the market while many collectors do not seem to be highly responsible for the quality of their products. To avoid this limitation, with the governmental support policy to improve farmers’ income, the processing plants set up a direct buying from farmers under contracts. These contracts led to a new governance type with an expectation of improving farmers' position. However, this model was broken due to several reasons including un-controlled shrimp raw material from small scale and individual farmers. Consequently, processors now tend to establish their own raw material zone to comply shrimp quality assurance, and eject the existence of farmers. This will lead small scale farmers to very difficult problems in finding the market. Poverty and social problems of small scale farmers might appear. The result recommends a greater strengthening and tightening of the value chain. Re-organizing shrimp farmers into legal teams or groups that help farmers to re-participate in the game with others actor in the chain is crucial. Research limitations/implications - The research mainly follows inductive approach in w

    Deriving and validating local adjusted calcium equations is important for ensuring appropriate calcium status classification. We investigated the impact on our local adjusted calcium equation of a change in calcium method by the manufacturer from cresolphthalein complexone to NM-BAPTA. Calcium and albumin results from general practice requests were extracted from the Laboratory Information Management system for a three-month period. Results for which there was evidence of disturbance in calcium homeostasis were excluded leaving 13,482 sets of results for analysis. The adjusted calcium equation was derived following least squares regression analysis of total calcium on albumin and normalized to the mean calcium concentration of the data-set. The revised equation (NM-BAPTA calcium method) was compared with the previous equation (cresolphthalein complexone calcium method). The switch in calcium assay resulted in a small change in the adjusted calcium equation but was not considered to be clinically significant. The calcium reference interval differed from that proposed by Pathology Harmony in the UK. Local adjusted calcium equations should be re-assessed following changes in the calcium method. A locally derived reference interval may differ from the consensus harmonized reference interval. © The Author(s) 2015.

  6. A new support measure to quantify the impact of local optima in phylogenetic analyses.

    2011-09-29

    Phylogentic analyses are often incorrectly assumed to have stabilized to a single optimum. However, a set of trees from a phylogenetic analysis may contain multiple distinct local optima with each optimum providing different levels of support for each clade. For situations with multiple local optima, we propose p-support which is a clade support measure that shows the impact optima have on a final consensus tree. Our p-support measure is implemented in our PeakMapper software package. We study our approach on two published, large-scale biological tree collections. PeakMapper shows that each data set contains multiple local optima. p-support shows that both datasets contain clades in the majority consensus tree that are only supported by a subset of the local optima. Clades with low p-support are most likely to benefit from further investigation. These tools provide researchers with new information regarding phylogenetic analyses beyond what is provided by other support measures alone.

    Full Text Available Purpose. In the present study, the prognostic significance of CpG island methylator phenotype (CIMP in stage II/III sporadic colorectal cancer was evaluated using a five-gene panel. Methods. Fifty stage II/III colorectal cancer patients who received radical resection were included in this study. Promoter methylation of p14ARF, hMLH1, p16INK4a, MGMT, and MINT1 was determined by methylation specific polymerase chain reaction (MSP. CIMP positive was defined as hypermethylation of three or more of the five genes. Impact factors on disease-free survival (DFS and overall survival (OS were analyzed using Kaplan-Meier method (log-rank test and adjusted Cox proportional hazards model. Results. Twenty-four percent (12/50 of patients were characterized as CIMP positive. Univariate analysis showed stage III (P=0.049 and CIMP positive (P=0.014 patients who had significantly inferior DFS. In Cox regression analysis, CIMP positive epigenotype was independently related with poor DFS with HR = 2.935 and 95% CI: 1.193–7.220 (P=0.019. In patients with CIMP positive tumor, those receiving adjuvant chemotherapy had a poor DFS than those without adjuvant chemotherapy (P=0.023. Conclusions. CIMP positive was significantly correlated with decreased DFS in stage II/III colorectal cancer. Patients with CIMP positive locally advanced sporadic colorectal cancers may not benefit from 5-fluorouracil based adjuvant chemotherapy.

  8. The impact of a and b value uncertainty on loss estimation in the reinsurance industry

    Full Text Available In the reinsurance industry different probabilistic models are currently used for seismic risk analysis. A credible loss estimation of the insured values depends on seismic hazard analysis and on the vulnerability functions of the given structures. Besides attenuation and local soil amplification, the earthquake occurrence model (often represented by the Gutenberg and Richter relation is a key element in the analysis. However, earthquake catalogues are usually incomplete, the time of observation is too short and the data themselves contain errors. Therefore, a and b values can only be estimated with uncertainties. The knowledge of their variation provides a valuable input for earthquake risk analysis, because they allow the probability distribution of expected losses (expressed by Average Annual Loss (AAL to be modelled. The variations of a and b have a direct effect on the estimated exceeding probability and consequently on the calculated loss level. This effect is best illustrated by exceeding probability versus loss level and AAL versus magnitude graphs. The sensitivity of average annual losses due to different a to b ratios and magnitudes is obvious. The estimation of the variation of a and b and the quantification of the sensitivity of calculated losses are fundamental for optimal earthquake risk management. Ignoring these uncertainties means that risk management decisions neglect possible variations of the earthquake loss estimations.

    The aim of the present study was to investigate the use and value of maximum standardized uptake value (SUV max) on positron emission tomography/computed tomography (PET/CT) images as a prognostic marker for patients with locally advanced pancreatic cancer (LAPC). The medical records of all consecutive patients who underwent PET/CT examination in our institution were retrospectively reviewed. Inclusion criteria were histologically or cytologically proven LAPC. Patients with distant metastasis were excluded. For statistical analysis, the SUV max of primary pancreatic cancer was measured. Survival rates were calculated using the Kaplan-Meier method, and multivariable analysis was performed to determine the association of SUV max with overall survival (OS) and progression-free survival (PFS) using a Cox proportional hazards model. Between July 2006 and June 2013, 69 patients were enrolled in the present study. OS and PFS were 14.9 months [95% confidence interval (CI) 13.1-16.7] and 8.3 months (95% CI 7.1-9.5), respectively. A high SUV max (>5.5) was observed in 35 patients, who had significantly worse OS and PFS than the remaining patients with a low SUV max (P = 0.025 and P = 0.003). Univariate analysis showed that SUV max and tumor size were prognostic factors for OS, with a hazard ratio of 1.90 and 1.81, respectively. A high SUV max was an independent prognostic factor, with a hazard ratio of 1.89 (95% CI 1.015-3.519, P = 0.045). The present study suggests that increased SUV max is a predictor of poor prognosis in patients with LAPC.

    This prospective observational study was undertaken to assess the impact of a major music festival on the workload of a local hospital. Data were collected on all attendances at Naas General Hospital from the nearby Oxegen 2004 music festival. Patient demographics, disposition and diagnoses were recorded. Emergency department activity levels were compared before, during and after the festival. Seventy-two attendees were referred to Naas emergency department over a 3-day period, representing a 45% increase in the hospital's emergency department attendance rate. Thirty-seven of these attendees (51%) required inpatient or tertiary centre services. Thirty-four attendees (47%) were noted as having consumed alcohol and/or used illicit substances. We conclude that despite the provision of on-site medical facilities, major music events are associated with a significant increase in local health care activity and expenditure.

    The water level in a polymer electrolyte membrane fuel cell (PEMFC) affects the durability as is seen from the degradation processes during operation a PEMFC with fully- and nonhumidified gas streams as analyzed using an in-situ segmented cell for local current density measurements during a 300 h test operating under constant conditions and using ex situ SEM/EDX and XPS post-test analysis of specific regions. The impact of the RH on spatial distribution of the degradation process results from different water distribution giving different chemical environments. Under nonhumidified gas streams, the cathode inlet region exhibits increased degradation, whereas with fully humidified gases the bottom of the cell had the higher performance losses. The degradation and the degree of reversibility produced by Pt dissolution, PTFE defluorination, and contaminants such as silicon (Si) and nickel (Ni) were locally evaluated.

    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.

  13. The Impact of Electoral System Reform on Taiwan’s Local Factions

    2012-01-01

    Full Text Available In 2004, the single non-transferable vote (SNTV was abolished in Taiwan. The SNTV had long been seen as a major factor in the sustenance of county- and township-level clientelist networks (“local factions”. It was also associated with phenomena such as extremism, candidate-centred politics, vote-buying, clientelism and organized crime involvement in politics. More recent scholarship, however, has led to doubts that a single formal institution like an electoral system could have such a powerful influence on electoral mobilization. This article puts these positions to an initial test. It examines the impact of the electoral reform on the mobilization capacity of a local faction in a rural county notorious for its factionalism. By illuminating its intricate mobilization structures, it provides support for the second position: These structures are too resilient to be affected by even a radical electoral reform.

    Whilst many patients treated with breast conservation undergo re-excision(s) to obtain clear margins, the relationship between clear margins and local recurrence remains unclear. We aimed to determine the impact of final pathological margin status on local recurrence and other breast cancer outcomes. Our study cohort consisted of 755 consecutive patients treated with breast conservation between January 1984 and December 1995. Pathology reports were available for review in 681subjects (90%). Patients were stratified into 8 groups based on final pathological margin status: 1) negative (>3mm, n = 307), close [further divided into two groups 2) >0 1< 2mm, (n = 67)], 4) positive (n= 79), 5) indeterminate (n= 144), 6) low grade DCIS at the margin (n= 3), 7) high grade DCIS at the margin (n= 23) and 8) LCIS at the margin (n= 4). There were no differences between the groups based on histology, T size, grade, LN positivity or total radiation dose. At a median follow-up of 71 months, the breast relapse free survival (BRFS) was 97%, the distant metastasis free survival (DMFS) 78% and the overall survival (OS) 86%, for the entire cohort. There were no statistically significant differences between the negative, close, and positive groups in terms of BRFS: 96% vs. 94% vs. 93% (p=0.59), MFS: 98% vs. 97% vs. 98% (p=0.87) or OS: 84%vs. 85% vs. 86% (p=0.78). Although not statistically significant, the presence of EIC, in the context of close or positive margins, impacted adversely upon local and overall disease free survival. Patients undergoing breast conservation carry a lifelong risk of local recurrence. It is still not clear whether obtaining a radical margin decreases this risk. Tissue microarray analysis will be performed to further elucidate the causes of ipsilateral recurrence at a molecular and genetic level

  16. Assessing the Impact of Landscape Development on Ecosystem Services Value in Tropical Watershed

    2014-01-01

    As development increases with demand, more forest lands are replaced with cropland, commercial plantation, and infrastructures for being able to accommodate the excessive growth in world's population. Environments were destroyed without considering their values in sustaining life on Earth.This phenomenon is still an ongoing scenario in most of the developing countries in the tropical region including Malaysia. Such unrestricted conversion may cause food or water crisis along with irreparable consequences to local and regional climate as the natural ecosystem is not only the main resources generator but also the climate stabilizer. Contrary to this, a study was conducted in Pahang Watershed, the largest watershed in Peninsular Malaysia with forest as the dominant land cover, to investigate the effect of landscape development on the ecosystem in terms of the erosion and ecosystem service value. Results of soil loss based on USLE indicated a direct relationship between development and total soil loss where total annual soil loss in year 2005 and 2010 showed a significant increase compare to year 2000. Meanwhile, developed and agricultural lands were discovered to be the main contributor whereas forest land produce the least soil loss (<10ton/ ha/yr). Apart from this, this study also reports a degrading trend in the overall ecological service value and goods (ESVG). Although oil palm had become the main commercial plantation in current years, the commercial profit brought by oil palm still insufficient to cover losses referring to overall estimated ESVG due to the forest clearance and soil degradation. In addition, for a destroyed ecosystem to be equilibrium again requires years. Therefore, ESVG of the tropical forest are expected to increase continuously in future which mean that the roles of the forest in conserving the environment stabilization and sustainability of life are getting more critical

    In our modern world, where people suffer from self-alienation and are after the meaning of existence in their mechanical and flamboyant outside world, finding a discernible language is very important. People's dejected minds are the products of miserable modern societies that have changed them into taciturn and uncommunicative creatures in search of meaning. The significance of language, specifically poetic or living language, is undeniable in different eras. Therefore, it would be easier for artists to communicate with people by letting them get the maximum meaning with the least amount of words. This is something that happens in the discourse of modern people. This article shows the aesthetic values of silence and its impacts on romantic and contemporary artists, who for us here will be represented by Samuel Taylor Coleridge as a romantic artist versus Harold Pinter as a contemporary dramatist.

  18. Application of risk-based value-impact analysis in a nuclear regulatory environment

    International Nuclear Information System (INIS)

    Dinnie, Keith; Land, Ronald; Stella, Mark

    1992-01-01

    Value-impact analysis (VIA) is a quantitative process that examines the benefits of proposed actions and the costs of implementing those actions to determine the potential for a net beneficial result. There is a point beyond which efforts to improve nuclear plant safety by implementing design changes will be unjustifiably expensive for the societal benefits obtained. Resources that would be used to obtain marginal improvements in public safety can then be used to obtain greater benefits for society in other areas. VIA can help to identify this point. What can not be accomplished by VIA is the definition of the level of risk (or safety) above which cost-benefit considerations are not applicable. This must be established separately, by political action or through promulgation of acceptable risk levels and safety goals by regulatory agencies. 18 refs

    2005-01-01

    To determine the potential impacts of lawn-care pesticides on aquatic ecosystems, the macroinvertebrate communities of six streams were assessed using a multimetric approach. Four streams flowed through residential neighborhoods of Peachtree City, GA, USA, with differing mean property values and two reference streams were outside the city limits. A series of correlation analyses were conducted comparing stream rank from water quality and physical stream parameters, habitat assessments, benthic macroinvertebrate metric, pesticide toxicity and metal toxicity data to determine relationships among these parameters. Significant correlations were detected between individual analyses of stream rank for pesticide toxicity, specific conductance, turbidity, temperature and dissolved oxygen with benthic macroinvertebrate metrics. - The macroinvertebrate communities of suburban streams may be influenced by the toxicity of the pesticides present in the water and sediment as well as select water quality parameters

  20. Firm Value and Cross Listings: The Impact of Stock Market Prestige

    Directory of Open Access Journals (Sweden)

    Nicola Cetorelli

    2015-03-01

    Full Text Available This study investigates the valuation impact of a firm’s decision to cross list on a more (or less prestigious stock exchange relative to its own domestic market. We use a network analysis methodology to derive broad market-based measures of prestige for 45 country or regional stock exchange destinations between 1990 and 2006. We find that firms cross listing in a more prestigious market enjoy significant valuation gains over the five-year period following the listing. In contrast, firms cross listing in less prestigious markets experience a significant valuation discount over this post-listing period. The reputation of the cross-border listing destinations is therefore a useful signal of firm value going forward. Our findings are consistent with the view that cross listing in a prestigious market enhances firm visibility, strengthens corporate governance, and lowers informational frictions and capital costs.

  1. Asset price and trade volume relation in artificial market impacted by value investors

    The relationship between return and trade volume has been of great interests in a financial market. The appearance of asymmetry in the price-volume relation in the bull and bear market is still unsettled. We present a model of the value investor traders (VIs) in the double auction system, in which agents make trading decision based on the pseudo fundamental price modelled by sawtooth oscillations. We investigate the system by two different time series for the asset fundamental price: one corresponds to the fundamental price in a growing phase; and the other corresponds to that in a declining phase. The simulation results show that the trade volume is proportional to the difference between the market price and the fundamental price, and that there is asymmetry between the buying and selling phases. Furthermore, the selling phase has more significant impact of price on the trade volume than the buying phase.

    The planned combined bridge and tunnel link between Sweden and Denmark (the Oresund Link) is expected to be in operation around the turn of the century. So far the impacts of the Oresund Link on air pollution have been discussed mainly in terms of changes in emissions, taking into account...... implications of the link on traffic in the region. It appears that the influence on regional and global air pollution will be marginal. Concerning local effects however, the situation is different; the new link across the Oresund and the island Amager will result in significant changes in traffic pattern...

    Vertigo and dizziness are common neurological complaints that have long been associated with epilepsy. However, studies of patients with epileptic vertigo or dizziness with concurrent EEG monitoring are scarce. We performed the present study to investigate the incidence and localizing value of vertigo and dizziness in patients with epilepsy who had confirmation of EEG changes via video-EEG monitoring. Data of aura and clinical seizure episodes of 831 consecutive patients who underwent video-EEG monitoring were analyzed retrospectively. Out of 831 patients, 40 patients (4.8%) experienced vertigo or dizziness as aura (mean age, 32.8±11.8years), all of whom had partial seizures. Eight had mesial temporal, 20 had lateral temporal, four had frontal, one had parietal, and seven had occipital lobe onset seizures. An intracranial EEG with cortical stimulation study was performed in seven patients, and the area of stimulation-induced vertigo or dizziness coincided with the ictal onset area in only one patient. Our study showed that vertigo or dizziness is a common aura in patients with epilepsy, and that the temporal lobe is the most frequent ictal onset area in these patients. However, it can be suggested that the symptomatogenic area in patients with epileptic vertigo and dizziness may not coincide with the ictal onset area. Copyright © 2016 Elsevier B.V.

    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

    Objective: To investigate the diagnostic value and the impact on surgical type classification of three-dimensional (3D) images for pre-surgical evaluation of dysplastic hips. Materials and methods: Three children with a different surgical type of hip dysplasia were investigated with helical computed tomography. For each patient, two-dimensional (2D) images, 3D, and a stereolithographic model of the dysplastic hip were generated. In two separate sessions, 40 medical observers independently analyzed the 2D images (session 1), the 2D and 3D images (session 2), and tried to identify the corresponding stereolithographic hip model. The influence of both image presentation (2D versus 3D images) and observer (degree of experience, radiologist versus orthopedic surgeon) were statistically analyzed. The SL model choice reflected the impact on surgical type classification. Results: Image presentation was a significant factor whereas the individual observer was not. Three-dimensional images scored significantly better than 2D images (P=0.0003). Three-dimensional imaging increased the correct surgical type classification by 35%. Conclusion: Three-dimensional images significantly improve the pre-surgical diagnostic assessment and surgical type classification of dysplastic hips

    The purpose of this study was to develop methodologies for establishing baseline datasets and statistical protocols for determining statistically significant changes between background concentrations and predicted concentrations that would be used to represent a contamination plume in the Gen II models being developed by NRAP’s Groundwater Protection team. The initial effort examined selected portions of two aquifer systems; the urban shallow-unconfined aquifer system of the Edwards-Trinity Aquifer System (being used to develop the ROM for carbon-rock aquifers, and the a portion of the High Plains Aquifer (an unconsolidated and semi-consolidated sand and gravel aquifer, being used to development the ROM for sandstone aquifers). Threshold values were determined for Cd, Pb, As, pH, and TDS that could be used to identify contamination due to predicted impacts from carbon sequestration storage reservoirs, based on recommendations found in the EPA’s ''Unified Guidance for Statistical Analysis of Groundwater Monitoring Data at RCRA Facilities'' (US Environmental Protection Agency 2009). Results from this effort can be used to inform a ''no change'' scenario with respect to groundwater impacts, rather than the use of an MCL that could be significantly higher than existing concentrations in the aquifer.

    Background Worker training is a core component of the OSHA Hazardous Waste Operations and Emergency Response (HAZWOPER) standard, but few studies have considered what motivates managers to provide HAZWOPER training to employees or what they value in that training. Methods In 2012, four university-based programs conducted an exploratory survey of managers who sent employees to HAZWOPER courses. Results from 109 respondents were analyzed. Results Forty-two percent of respondents cited regulations as the most important reason to provide HAZWOPER training; many indicated they would provide less training if there were no standard in place. Three-quarters (74%) reported training had improved workplace conditions. Fewer than half said they were likely to involve trained employees in aspects of the organization’s H&S program. Discussion Compliance with regulatory requirements is an important factor shaping managers’ training delivery decisions. Managers recognize positive impacts of training. These impacts could be enhanced by further leveraging employee H&S knowledge and skills. PMID:26010141

    Objective: To investigate the prognostic value of overall treatment time (OTT) for locally advanced nasopharyngeal carcinoma (NPC) treated with intensity-modulated radiation therapy (IMRT). Methods: From May 2001 to April 2007, 376 patients with locally advanced NPC treated with IMRT were retrospectively analyzed. All patients were divided into OTT≤45 days group and OTT >45 days group. The treatment outcomes between the two groups were analyzed. Results: Between the groups with OTT≤45 days and OTT > 45 days, the 2-year local control rate (LCR) was 94.9% and 93.1% (χ 2 = 2.83, P > 0.05) for all patients, 96.3% and 98.7% (χ 2 =2.83, P>0.05) for patients with T 3 disease, 92.2% and 83.1%(χ 2 = 6.30, P 4 , and 93.1% and 97.5% (χ 2 = 4.69, P = 0.030) when chemotherapy was concurrently administered.The 2-year LCR was 98%, 96% and 93% (χ 2 = 2.20, P = 0.531) for patients with treatment interruption before, within and after the 3rd week of IMRT, The Cox regression analysis found that OTT was an independent prognostic factor for LCR in T 4 disease.The Linear regression showed that the 2-year LCR was decreased by 2.7% per day of delay. Between the groups with OTT≤45 days and OTT >45 days, the 2-year estimated disease-specific survival (DSS), distant metastasis-free survival (DMFS) and overall survival (OS) were 84.1% vs.78.7% (χ 2 = 0.02, P = 0.881), 87.0% vs.86.1% (χ 2 = 0.85, P = 0.358), and 91.7% vs. 92.2% (χ 2 = 0.06, P = 0.806), respectively.The further stratified analysis found that the DSS, DMFS and OS were similar between the two groups in T 3 (83.7% vs. 83.2%, χ 2 =0.07, P=0.798; 86.6% vs. 85.7%, χ 2 =0.02, P = 0.898 ; and 93.7% vs. 94.8%, χ 2 =0.03, P=0.862) and T 4 disease (81.4% vs. 72.3%, χ 2 = 0.16, P = 0.687; 82.6% vs. 86.9%, χ 2 = 1.78, P =0.182; and 88.3% vs. 87.5%, χ 2 =0.60, P =0.438).In multivariate analysis, T-stage and N-stage were the independent prognostic factors for both DFS and OS, and N-stage was the independent prognostic

    2010-07-01

    Court decisions in 1998 encouraged generic producers to pursue Paragraph IV patent challenges. A follow-up decision in 2000 marked the first successful challenge involving a blockbuster and brought further attention to this pathway for generic entry. We consider the impacts of these decisions on R&D-based startups, and we focus on the propensity to form alliances as a primary channel of impact. We find substantial negative impacts on alliance formation and firm value, and only the first event's impacts are restricted to small molecules. The results suggest that policy analyses in settings with R&D-based startups should consider impacts on alliance formation.

    Since the Victorian Audit of Surgical Mortality (VASM) commenced in 2007, 95% of Victorian Fellows have agreed to participate and have provided data on the deaths of patients receiving surgical care. All public, and the majority of private, hospitals involved in the delivery of surgical services in Victoria have been submitting data on deaths associated with surgery. De-identified reports on this data are distributed in regular annual reports and case note review booklets. Although informal feedback on the perceived value of the audit was encouraging, a formal review of all aspects of the audit was felt necessary. An independent formal review of VASM governance, documentation, datasets and data analysis was performed, in addition to a survey of 257 individuals (surgeons and other stakeholders) on the perceived impact of VASM. The review confirmed increasing participation and acceptance by surgeons since the inception of the project. Governance mechanisms were found to be effective and acknowledged by stakeholders and collaborators. Robust participation rates have been achieved, and stakeholders were generally satisfied with the quality of feedback. Suggestions for improvement were provided by some surgeons and hospitals. External review of VASM processes and procedures confirmed that the audit was operating effectively, with robust quality control and achieving the trust of stakeholders. The educational value of the audit to the surgical community was acknowledged and areas for future improvement have been identified. © 2013 Royal Australasian College of Surgeons.

    Full Text Available From the ‘Agency Theory' and the conflict of interest assumption the aim of this study is verify the impact of the use of two classes of shares (dual class on the value in brazilian companies. The sample consisted of non-financial traded companies, with concentrated ownership structure, data are available in Economática®, totaling 354 companies and 1,915 observations. The data refer to the period 2005 to 2012. It terms of methodology, to research the hypothesis of the study it was used a regression by ordinary least squares, with panel data. The results indicate that companies using two classes of shares, such as separation mechanism between the cash flow and the equity control, have lower value then the ones not using such a mechanism. Additionally, it can be inferred that the governance levels and the higher dividend payment policy in the preferred shares are not able to mitigate the higher level of conflicts of interest and agency costs in dual class companies.

  14. Innovation in Hungary - The Impact of EU Accession and Integration into Global Value Chains

    Directory of Open Access Journals (Sweden)

    2014-11-01

    Full Text Available This paper argues that EU accession has brought about minimal changes in the patterns of innovation in Hungary. The reason why is not that the ‘EU factor’ is of minor importance; rather, it is Hungary's inability to use EU resources effectively, so as to fully benefit from EU membership. The Hungarian story also demonstrates that the EU cannot block member states from reversing reform or abusing the opportunities EU membership offers to them. We contend that globalization (global value chain integration has more effectively contributed to Hungary's knowledge-based upgrading than Europeanization (in the sense of policy transfer; access to EU Structural & Cohesion Funds, and integration in the European Research Area. This argument is substantiated with a case study on innovation strategy design and implementation, which illustrates the ambiguous impact of Europeanization, which is contrasted with our investigation of integration in global value chains, conducted through interviews of foreign-owned manufacturing companies about their R&D-based upgrading experience.

    Quasi-experimental methods increasingly are used to evaluate the impacts of conservation interventions by generating credible estimates of counterfactual baselines. These methods generally require large samples for statistical comparisons, presenting a challenge for evaluating innovative policies implemented within a few pioneering jurisdictions. Single jurisdictions often are studied using comparative methods, which rely on analysts' selection of best case comparisons. The synthetic control method (SCM) offers one systematic and transparent way to select cases for comparison, from a sizeable pool, by focusing upon similarity in outcomes before the intervention. We explain SCM, then apply it to one local initiative to limit deforestation in the Brazilian Amazon. The municipality of Paragominas launched a multi-pronged local initiative in 2008 to maintain low deforestation while restoring economic production. This was a response to having been placed, due to high deforestation, on a federal "blacklist" that increased enforcement of forest regulations and restricted access to credit and output markets. The local initiative included mapping and monitoring of rural land plus promotion of economic alternatives compatible with low deforestation. The key motivation for the program may have been to reduce the costs of blacklisting. However its stated purpose was to limit deforestation, and thus we apply SCM to estimate what deforestation would have been in a (counterfactual) scenario of no local initiative. We obtain a plausible estimate, in that deforestation patterns before the intervention were similar in Paragominas and the synthetic control, which suggests that after several years, the initiative did lower deforestation (significantly below the synthetic control in 2012). This demonstrates that SCM can yield helpful land-use counterfactuals for single units, with opportunities to integrate local and expert knowledge and to test innovations and permutations on policies

    Vulnerability Assessment is usually used for assessing the ability of an area on facing disaster. In previous studies, the study of Vulnerability Assessment applied only quantitative method to show the vulnerability level. Therefore, this study attempts to add information reviews using qualitative method. Kemijen City Village is one of the administrative areas in the northern part of Semarang City affected by climate change. The residents have to adapt it by renovating and elevating their houses and other infrastructures to avoid floods. There are some development programs held by government, NGOs, and corporations such as Banger Polder Development, PLPBK, etc. It is interesting to know how big the vulnerability level of Kemijen on facing flood disasters, then how the projects can affect local adaptive capacity. To answer it, this research uses mixed-method approach. Vulnerability Assessment uses quantitative method by scoring indicators of Exposure, Sensitivity, and Adaptive Capacity, while the development impact uses qualitative method. The data were collected through interviews and FGD conducted in Joint Studio Course between Diponegoro University and University of Hawaii in October 2016. Non-physical programs such as community empowerment have more positive impacts on local adaptive capacity in Kemijen. Community participation is important for environmental sustainability that can not be done in a short time to educate the people.

    The mitigating impact of thermal and rectified radio frequency (RF) sheath potentials on the peeling-ballooning modes is studied non-linearly by employing a two-fluid three-field simulation model based on the BOUT++ framework. Additional shear flow and the Kelvin-Helmholtz effect due to the thermal and rectified RF sheath potential are induced. It is found that the shear flow increases the growth rate while the K-H effect decreases the growth rate slightly when there is a density gradient, but the energy loss of these cases is suppressed in the nonlinear phase. The stronger external electrostatic field due to the sheaths has a more significant effect on the energy loss suppression. From this study, it is found the growth rate in the linear phase mainly determines the onset of edge-localized modes, while the mode spectrum width in the nonlinear phase has an important impact on the turbulent transport. The wider mode spectrum leads to weaker turbulent transport and results in a smaller energy loss. Due to the thermal sheath and rectified RF sheath potential in the scrape-off-layer, the modified shear flow tears apart the peeling-ballooning filament and makes the mode spectrum wider, resulting in less energy loss. The perturbed electric potential and the parallel current near the sheath region is also suppressed locally due to the sheath boundary condition.

    Full Text Available Law 11.638/07 marked the start of a series of changes in the laws that regulate Brazilian accounting practices. The main reason for these changes is the convergence process of local with international accounting standards. As a result of Law 11.638/07, the legal precedent was established to achieve convergence. In that context, the aim of this study is to analyze the impact of the convergence process with international accounting standards on the relevance of financial information, based on data for 2007, without and with the alterations Law 11.638/07 introduced and according to the CPC Pronouncements, applicable as from 2008 onwards. Therefore, a value relevance study is used, applying regression analysis to annual stock price information (dependent variable and net profit per share (NPPS and net equity per share (NEPS as independent variables. The main results show that financial information on NPPS and NEPS for 2007, with and without the legal alterations, are relevant for the capital market. A comparison between both regressions used in the analysis, however, shows an information gain for financial information that includes the changes introduced in the first phase of the accounting convergence process with the international standards.

    Full Text Available The study on Panemunė Castle examined this heritage object in an entirety of its values and their impact on the environment, with a possibility of their synergism for the benefit of the place. It found the contemporary national heritage protection framework failing to grant equal attention to elements constituting the multifaceted worth of the castle as a property, inclusive of the social, cultural, artistic values, the engagement of local communities, the important role of cultural tourism and the image of the place, and economic efficiency. The analysis of the different facets one by one and collectively has brought to the conclusion that the social, cultural, artistic and economic values of Panemunė Castle as a heritage property influence their environment, but are not experienced as a powerful driving force of the contemporary heritage protection. The process remains fragmented, sporadic and underdeveloped, with its elements failing to achieve synergism for the place.

    equal opportunities, financial security during illness not as simple care of the sick. The paper includes analysis related to: the structure of social protection in our country, the scope of these services, the relationship between social protection and poverty, the way and the degree to which social protection deepens or contribute to poverty reduction. The economic crisis triggered in Europe in 2008that also affects Romania, negatively influenced the evolution of social funds in key areas of public interest, education, health and social care. This results from: decreasing share of social spending in the state budget, decreasing share of these expenses in the total family budget due to lower purchasing power and thus the obligation of individual to reduce or waive some costs of this kind, central and local government bodies inability to meet certain service requirements such at the level of the population and especially low-income population groups. Located in the crisis situation the state must seek solutions to keep social services at an appropriate level because the quantity and quality of these services have an impact upon quality of life and standard of living of many individuals. The results of the analysis indicates us a reduced benefit for this type of service, in our country, with negative effects over the entire society. The conclusions aim to support the fact that social policy from our country is insufficient in relation to the real needs of the population, being strongly influenced by domestic economic situation and the size of the global economic crisis.

  5. The Impact Of Integrated Parameters In The Manga Local Mass-Metallicity Relation

    We present the surface mass density - gas metallicity (Σ_*-Z) relation for more than 500,000 spatially-resolved star-forming regions from a sample of 617 disk galaxies included in the MaNGA survey. We find a tight relation between these local properties with higher metallicities as the surface density increases, resembling a scaled-down version of the relation found previously for their integrated counterparts. This relation expands over three orders of magnitude in the surface mass and a factor of 8 in metallicity. Our large sample allows us to study the impact of global properties in this local relation. In particular, we find that for most disk galaxies the Σ_*-Z relation does not depend on the total stellar mass. Even more, for a large fraction of our sample (log(M_*/M_{⊙}) > 9.2) the observed metallicity gradients are well reproduced by the mass density gradients and the Σ_*-Z relation. We also find that this relation does not change significantly within the range of redshifts span by our sample. Our results suggest as the predominant scenario for metal enrichment as gas been recycled locally at shorter timescales in comparison to other global processes such as gas accretion or outflows.

  6. Evaluating the impact of agritourism on local development in small islands

    2016-05-01

    Full Text Available Tourism is an activity encompassing economy, society and nature. Besides mass tourism, many different forms of tourism activities and products have developed and are gaining ground in terms of demand. Debates on the definition of such typically small scale activities have brought forward a number of different types, including ‘agrotourism’, ‘agri-tourism’ and ‘rural tourism’. This paper contributes to the conceptual analysis of agritourism with a focus on its effects on local development. After a brief historical sketch of agritourism development, the effects on local development found in the literature are presented. Then, a typology of different forms of agritourism is discussed, including aspects of supply and demand, the scale of operation of the enterprises and networks of enterprises related to agritourism. Finally, we explore the case of small islands, a special type of space, and their local development with these types of ‘alternative’ tourism activities alongside ‘conventional’ tourism. The conceptual framework that results suggests the need for a case and area specific mapping of type, scale and network of enterprises in order to determine impacts and provide important information for managing and planning agritourism, especially on islands.

    As development increases with demand, more forest lands are replaced with cropland, commercial plantation, and infrastructures for being able to accommodate the excessive growth in world's population. Environments were destroyed without considering their values in sustaining life on Earth.This phenomenon is still an ongoing scenario in most of the developing countries in the tropical region including Malaysia. Such unrestricted conversion may cause food or water crisis along with irreparable consequences to local and regional climate as the natural ecosystem is not only the main resources generator but also the climate stabilizer. Contrary to this, a study was conducted in Pahang Watershed, the largest watershed in Peninsular Malaysia with forest as the dominant land cover, to investigate the effect of landscape development on the ecosystem in terms of the erosion and ecosystem service value. Results of soil loss based on USLE indicated a direct relationship between development and total soil loss where total annual soil loss in year 2005 and 2010 showed a significant increase compare to year 2000. Meanwhile, developed and agricultural lands were discovered to be the main contributor whereas forest land produce the least soil loss (oil palm had become the main commercial plantation in current years, the commercial profit brought by oil palm still insufficient to cover losses referring to overall estimated ESVG due to the forest clearance and soil degradation. In addition, for a destroyed ecosystem to be equilibrium again requires years. Therefore, ESVG of the tropical forest are expected to increase continuously in future which mean that the roles of the forest in conserving the environment stabilization and sustainability of life are getting more critical.

    Air pollution exposure reduces life expectancy. Air pollution, deprivation and poor-health status combinations can create increased and disproportionate disease burdens. Problems and solutions are rarely considered in a broad public health context, but doing so can add value to air quality management efforts by reducing air pollution risks, impacts and inequalities. An ecological study assessed small-area associations between air pollution (nitrogen dioxide and particulate matter), deprivation status and health outcomes in Wales, UK. Air pollution concentrations were highest in 'most' deprived areas. When considered separately, deprivation-health associations were stronger than air pollution-health associations. Considered simultaneously, air pollution added to deprivation-health associations; interactions between air pollution and deprivation modified and strengthened associations with all-cause and respiratory disease mortality, especially in 'most' deprived areas where most-vulnerable people lived and where health needs were greatest. There is a need to reduce air pollution-related risks for all. However, it is also the case that greater health gains can result from considering local air pollution problems and solutions in the context of wider health-determinants and acting on a better understanding of relationships. Informed and co-ordinated air pollution mitigation and public health action in high deprivation and pollution areas can reduce risks and inequalities. To achieve this, greater public health integration and collaboration in local air quality management policy and practice is needed. © The Author 2016.

  9. Urban Heat Islands and Their Mitigation vs. Local Impacts of Climate Change

    Taha, H.

    2007-12-01

    Urban heat islands and their mitigation take on added significance, both negative and positive, when viewed from a climate-change perspective. In negative terms, urban heat islands can act as local exacerbating factors, or magnifying lenses, to the effects of regional and large-scale climate perturbations and change. They can locally impact meteorology, energy/electricity generation and use, thermal environment (comfort and heat waves), emissions of air pollutants, photochemistry, and air quality. In positive terms, on the other hand, mitigation of urban heat islands (via urban surface modifications and control of man-made heat, for example) can potentially have a beneficial effect of mitigating the local negative impacts of climate change. In addition, mitigation of urban heat islands can, in itself, contribute to preventing regional and global climate change, even if modestly, by helping reduce CO2 emissions from power plants and other sources as a result of decreased energy use for cooling (both direct and indirect) and reducing the rates of meteorology-dependent emissions of air pollutants. This presentation will highlight aspects and characteristics of heat islands, their mitigation, their modeling and quantification techniques, and recent advances in meso-urban modeling of California (funded by the California Energy Commission). In particular, the presentation will focus on results from quantitative, modeling-based analyses of the potential benefits of heat island mitigation in 1) reducing point- and area-source emissions of CO2, NOx, and VOC as a result of reduced cooling energy demand and ambient/surface temperatures, 2) reducing evaporative and fugitive hydrocarbon emissions as a result of lowered temperatures, 3) reducing biogenic hydrocarbon emissions from existing vegetative cover, 4) slowing the rates of tropospheric/ground-level ozone formation and/or accumulation in the urban boundary layer, and 5) helping improve air quality.

    Agricultural irrigation practice is one of the important anthropogenic processes in the land surface modeling. Irrigation can decrease local surface temperature with alternating surface energy partitioning. Rice paddy is the major food crop in Asian monsoon region and rice is grown under flooded conditions during the growing season; hence, the rice paddy can be considered as an open water body, which has more impacts on the surface energy budget than other cropland does. In this study, we explore how the rice paddy area changes affect Taiwan's regional climate from both observational data and numerical modeling exercise. The Weather Research and Forecasting (WRF) model is utilized to explore impacts of rice paddy area changes on the regional climate, and energy and water budget changes. In addition, temperature datasets from six automatic weather stations in the northern Taiwan and two stations in the southern Taiwan are analyzed in this study to explore how the Daily Temperature Range (DTR) changes with the decreased rice paddy areas. Previous studies show that due to the urban heat island effect, aerosol direct and indirect effects, and global warming, the DTR has decreased in the past 4 decades observed from most of the weather stations around Taiwan. However, the declined rice paddy area may increase the DTR with higher Bowen ratio during the daytime. Preliminary results show that DTR is decreased in weather stations near the urban area, but increased in weather stations near fallow areas in the past 20 years. It shows that different land use changes may have opposite impacts on local and regional climate.

    2016-11-01

    This paper presents the local laser heating process of surface layer of the metal sample. The aim is to create the molten pool with the required depth by laser thermal treatment. During the heating the metal temperature at any point of the molten zone should not reach the boiling point of the main material. The laser power, exposure time and the spot size of a laser beam are selected as the variable parameters. The mathematical model for heat transfer in a semi-infinite body, applicable to finite slab, is used for preliminary theoretical estimation of acceptable parameters values of the laser thermal treatment. The optimization problem is solved by using an algorithm based on the scanning method of the search space (the zero-order method of conditional optimization). The calculated values of the parameters (the optimal set of "laser radiation power - exposure time - spot radius") are used to conduct a series of natural experiments to obtain a molten pool with the required depth. A two-stage experiment consists of: a local laser treatment of metal plate (steel) and then the examination of the microsection of the laser irradiated region. According to the experimental results, we can judge the adequacy of the ongoing calculations within the selected models.

    Full Text Available We investigated the impact of Acacia drepanolobium, a species threatening rangeland resources including Gum-resin production and pastoralists’ livelihoods in Borana. Data were collected through vegetation surveys, key informant interviews, use of formal questionnaires and focus group discussions. We found a total of 22 woody species in the study area. A. drepanolobium was found to be the most dominant (22% and abundant (65% invasive woody species with an importance value index (IVI of 103. According to our respondents, A. drepanolobium was the first widely expanded woody species followed by Dichrostachys cinerea and A. mellifera. Eighty seven percent of our respondents ranked A. drepanolobium as the most invading woody species during their life time. Overall, our results demonstrated that the impact of A. drepanolobium had greatly affected the condition of rangeland vegetation. The implication is that the reduction in the capacity of rangelands for livestock grazing could reduce the resilience of local livelihood under changing environmental conditions. Furthermore, pastoralists’ perception indicated that the expansion of A. drepanolobium had reduced the survival of Gum-resin producing species. Generally, the shift from cattle based pastoral economy to mixed livestock types could be attributed to the expansion of A. drepanolobium that forced the community to shift their mode of production. We confirmed that A. drepanolobium is an invasive indigenous woody species with multiple effects on the ecology of rangelands and on the livelihood security of pastoral communities.

    2014-12-01

    Comprehensive climate impacts assessments are important vehicles for conveying salient information to the public and policy makers. However, over the last few decades communication of this important information has been hampered for a number of reasons. Firstly, we have a rapidly changing social media landscape, where there are fewer opportunities for in-depth treatment of issues. To compete in this arena, climate information needs to be packaged in sound bites, and much of the nuance and complexity may be lost. Secondly, scientific literacy among the general U.S. population is not particularly high, which creates a barrier to understanding and limits the audiences that can be reached. Thirdly, climate science has been undermined by misinformation over many years often funded by fossil fuel interests. While this latter obstacle is clearly diminishing - largely in the face of evidence from the undeniable climate impacts that are already being seen by communities - there has been much confusion generated to date. Despite the fact that 97% of active climate scientists agree that the planet is warming as a result of human greenhouse gas emission, only 42% of the U.S. population agrees (Pew Research, 2013). In the face of these challenges, much of the work that the Union of Concerned Scientists does to translate climate impacts assessments has shifted to visuals, animations, and videos that people can relate to and connect with more readily. In this session we will share some of the general design features, discuss target audiences, and outline production limitations of several local stories involving videos and animations, as well as present some recent infographics. One example of this work are case studies that focus on sea level rise and involve a local personality who can speak to climate impacts at the community level. We understand the power of visual images and stories in creating messages that stick, and we use this in designing animations that explain the

    2016-12-01

    Drugs used chronically by patients with diseases of the cardiovascular system (group C of the ATC classification) may act on adrenergic receptors and/or certain ion channels, which gives them the potential to interact with the action of local dental anesthetics. The aim of the study was to investigate the effect of systemically administered chronic cardiovascular medication (oral route) on the efficacy of intraoral local anesthesia in patients with diseases of the cardiovascular system. This was a prospective cohort study which analyzed the efficacy of local terminal anesthesia (onset of anesthesia, duration anesthetized area) in the upper jaw of 70 patients: 40 patients on medication for cardiovascular system disorders and 30 patients who were not using these drugs (the control group). The following cardiovascular drugs were used: beta blockers, angiotensin converting enzyme inhibitors, calcium channel blockers, vasodilatators, diuretics, angiotensin receptor blockers, antiarrhythmics, statins and alfa blockers. The onset of anesthesia on the vestibular side was faster in those taking cardiovascular drugs (40.50±19.87 s) than the control patients (58.93±31.07 s; P = 0.004) and duration of anesthesia on this side was shorter. Although the difference was not significant, it was evident that on vestibular and palatal side the anesthetized area was more rapidly reduced in the patients taking cardiovascular drugs. The duration of cardiovascular therapy also had a significant impact on the anesthetized area. Drugs acting on cardiovascular system may influence the effect of local anesthetics used in dentistry, possibly through interaction with autonomic receptors and ion channels.

  16. Local Social and Environmental Impacts of Biofuels: Global Comparative Assessment and Implications for Governance

    Directory of Open Access Journals (Sweden)

    2011-12-01

    Full Text Available The 2000s witnessed the rapid expansion of biofuel plantations in the global South in the context of a growing trend of crop plantation expansion. This trend has been spurred by policies in the European Union, United States, Brazil, and other countries favoring the use of biofuels in the transport sector to enhance energy security and reduce carbon emissions, as well as by the desire of governments in developing countries to harness the stimulus that new commercial investments provide to the agricultural sector and to national economies. Despite these potential benefits, a number of concerns have been raised about the local social and environmental impacts of biofuel feedstock expansion. We shed light on this debate through a synthesis of findings from case studies in six biofuel producer countries of Asia, Africa, and Latin America, and a seventh paper exploring the implications of the land-use changes observed in these case studies for the climate mitigation potential of biofuels. We also explore the implications for governing the environmental impacts of biofuel feedstock production, protecting the rights of customary land users, and enabling smallholder-inclusive business models. Our analysis suggests that better governance of the sector's impacts is not the exclusive preserve of unitary sets of actors, but instead requires concerted and coordinated efforts by governments of producer and consumer countries, investors, civil society, and the financial sector to better capture the sector's potential while minimizing its social and environmental costs.

    In the study presented here the environmental impacts of the infrastructure and the use of wireless LAN are investigated and compared to wired LAN. In order to determine if and under which conditions WLAN shows environmental benefits a comparison with a wired LAN was drawn on the basis of three exemplary applications. The environmental impacts of the life cycle of these applications were assessed using the method of LCA. The investigated systems include the production, the operation of the networks and their end of life stage. The three applications under investigation were the following: application 1: a peer-to-peer connection of two computers; application 2: a small network consisting of three computers like it is used in households and small offices (SOHO) and application 3: an office network consisting of 20 computers. The results showed no significant differences between the two alternatives for the applications 1 and 2 taking into account cumulative energy demand, global warming potential, acidification potential and photochemical oxidation potential as impact categories. In contrast to this a significant advantage for the wireless solution could be identified for the third application. Concerning electronic waste-arise, the wireless solution is advantageous for all three applications. From the results recommendations for equipment options, net structure, and use behaviour of local area networks are derived. (orig.)

  18. Regulatory environment and its impact on the market value of investor-owned electric utilities

    Vishwanathan, Raman

    While other regulated industries have one by one been exposed to competitive reform, electric power, for over eighty years, has remained a great monopoly. For all those years, the vertically integrated suppliers of electricity in the United States have been assigned exclusive territorial (consumer) franchises and have been closely regulated. This environment is in the process change because the electric power industry is currently undergoing some dramatic adjustments. Since 1992, a number of states have initiated regulatory reform and are moving to allow retail customers to choose their energy supplier. There has also been a considerable federal government role in encouraging competition in the generation and transmission of electricity. The objective of this research is to investigate the reaction of investors to the prevailing regulatory environment in the electric utility industry by analyzing the market-to-book value for investor-owned electric utilities in the United States as a gauge of investor concern or support for change. In this study, the variable of interest is the market valuation of utilities, as it captures investor confidence to changes in the regulatory environment. Initially a classic regression model is analyzed on the full sample (of the 96 investor-owned utilities for the years 1992 through 1996), providing a total number of 480 (96 firms over 5 years) observations. Later fixed- and random-effects models are analyzed for the same full-sample model specified in the previous analysis. Also, the analysis is carried forward to examine the impact of the size of the utility and its degree of reliability on nuclear power generation on market values. In the period of this study, 1992--1996, the financial security markets downgraded utilities that were still operating in a regulated environment or had a substantial percentage of their power generation from nuclear power plants. It was also found that the financial market was sensitive to the size of

    1989-01-01

    A value impact analysis (VIA) has been performed by the INEL to support a NRC Regulatory Analysis for resolution of Generic Issue (GI) 29, Bolting Degradation or Failure in Nuclear Power Plants. A VIA for replacing the reactor coolant pressure boundary (RCPB) bolts of BWRs and PWRs was previously prepared by Pacific Northwest Laboratories in 1985 under instructions limiting the VIA to the potential for failure of primary pressure boundary bolting. Subsequently the INEL was requested to perform a VIA that included non primary systems and component support bolts to be compatible with the resolution of the broader issue. Because the initial list of systems and bolting applications that could be included in the VIA was very large, including them all in the VIA would likely result in analyzing some that have little if any effect on public risk. This paper discusses how PRA techniques combined with a hybrid plant model were used to determine which bolts have the potential to be significant contributors to public risk if they were to fail, and therefore were included in the VIA

    Full Text Available A hedonic model for estimating the effects of transit systems on real estate values is specified and calibrated for the city of Naples. The model is used to estimate the external benefits concerning property values which may be attributed to the Naples metro at the present time and in two future scenarios. The results show that only high-frequency metro lines have appreciable effects on real estate values, while low-frequency metro lines and bus lines produce no significant impacts. Our results show that the impacts on real estate values of the metro system in Naples are significant, with corresponding external benefits estimated at about 7.2 billion euros or about 8.5% of the total value of real estate assets.

    Based on simulations with the Chemical Lagrangian Model of the Stratosphere (CLaMS) for the period 1979-2013, with model transport driven by the ECMWF ERA-Interim reanalysis, we discuss the impact of the El Niño Southern Oscillation (ENSO) on the variability of the dynamics, water vapor, ozone, and mean age of air (AoA) in the tropical lower stratosphere during boreal winter. Our zonally resolved analysis at the 390 K potential temperature level reveals that not only (deseasonalized) ENSO-related temperature anomalies are confined to the tropical Pacific (180-300°E) but also anomalous wave propagation and breaking, as quantified in terms of the Eliassen-Palm (EP) flux divergence, with strongest local contribution during the La Niña phase. This anomaly is coherent with respective anomalies of water vapor (±0.5 ppmv) and ozone (±100 ppbv) derived from CLaMS being in excellent agreement with the Aura Microwave Limb Sounder observations. Thus, during El Niño a more zonally symmetric wave forcing drives a deep branch of the Brewer-Dobson (BD) circulation. During La Niña this forcing increases at lower levels (≈390 K) over the tropical Pacific, likely influencing the shallow branch of the BD circulation. In agreement with previous studies, wet (dry) and young (old) tape recorder anomalies propagate upward in the subsequent months following El Niño (La Niña). Using CLaMS, these anomalies are found to be around +0.3 (-0.2) ppmv and -4 (+4) months for water vapor and AoA, respectively. The AoA ENSO anomaly is more strongly affected by the residual circulation (≈2/3) than by eddy mixing (≈1/3).

    This report summarizes initial modeling of the local response of the Bigelow Expandable Activity Module (BEAM) to micrometeorite and orbital debris (MMOD) impacts using a structural, non-linear, transient dynamic finite element code. Complementary test results for a local BEAM structure are presented for both hammer and projectile impacts. Review of these data provided guidance for the transient dynamic model development. The local model is intended to support predictions using the global BEAM model, described in a companion report. Two types of local models were developed. One mimics the simplified Soft-Goods (fabric envelop) part of the BEAM NASTRAN model delivered by the project. The second investigates through-the-thickness modeling challenges for MMOD-type impacts. Both the testing and the analysis summaries contain lessons learned and areas for future efforts.

  8. Monitoring, modeling and mitigating impacts of wind farms on local meteorology

    Science.gov (United States)

    Baidya Roy, Somnath; Traiteur, Justin; Kelley, Neil

    2010-05-01

    Wind power is one of the fastest growing sources of energy. Most of the growth is in the industrial sector comprising of large utility-scale wind farms. Recent modeling studies have suggested that such wind farms can significantly affect local and regional weather and climate. In this work, we present observational evidence of the impact of wind farms on near-surface air temperatures. Data from perhaps the only meteorological field campaign in an operational wind farm shows that downwind temperatures are lower during the daytime and higher at night compared to the upwind environment. Corresponding radiosonde profiles at the nearby Edwards Air Force Base WMO meteorological station show that the diurnal environment is unstable while the nocturnal environment is stable during the field campaign. This behavior is consistent with the hypothesis proposed by Baidya Roy et al. (JGR 2004) that states that turbulence generated in the wake of rotors enhance vertical mixing leading to a warming/cooling under positive/negative potential temperature lapse rates. We conducted a set of 306 simulations with the Regional Atmospheric Modeling System (RAMS) to test if regional climate models can capture the thermal effects of wind farms. We represented wind turbines with a subgrid parameterization that assumes rotors to be sinks of momentum and sources of turbulence. The simulated wind farms consistently generated a localized warming/cooling under positive/negative lapse rates as hypothesized. We found that these impacts are inversely correlated with background atmospheric boundary layer turbulence. Thus, if the background turbulence is high due to natural processes, the effects of additional turbulence generated by wind turbine rotors are likely to be small. We propose the following strategies to minimize impacts of wind farms: • Engineering solution: design rotors that generate less turbulence in their wakes. Sensitivity simulations show that these turbines also increase the

  9. A single frequency component-based re-estimated MUSIC algorithm for impact localization on complex composite structures

    2015-01-01

    The growing use of composite materials on aircraft structures has attracted much attention for impact monitoring as a kind of structural health monitoring (SHM) method. Multiple signal classification (MUSIC)-based monitoring technology is a promising method because of its directional scanning ability and easy arrangement of the sensor array. However, for applications on real complex structures, some challenges still exist. The impact-induced elastic waves usually exhibit a wide-band performance, giving rise to the difficulty in obtaining the phase velocity directly. In addition, composite structures usually have obvious anisotropy, and the complex structural style of real aircrafts further enhances this performance, which greatly reduces the localization precision of the MUSIC-based method. To improve the MUSIC-based impact monitoring method, this paper first analyzes and demonstrates the influence of measurement precision of the phase velocity on the localization results of the MUSIC impact localization method. In order to improve the accuracy of the phase velocity measurement, a single frequency component extraction method is presented. Additionally, a single frequency component-based re-estimated MUSIC (SFCBR-MUSIC) algorithm is proposed to reduce the localization error caused by the anisotropy of the complex composite structure. The proposed method is verified on a real composite aircraft wing box, which has T-stiffeners and screw holes. Three typical categories of 41 impacts are monitored. Experimental results show that the SFCBR-MUSIC algorithm can localize impact on complex composite structures with an obviously improved accuracy. (paper)

    contingent of about 50% of rural homeless during this event. On the ther side, during the extreme droughts, crops and cattle are likely to perish due to drought. The prolonged dry season threatens local ichthyofauna, promoting an increase in fish mortality. In 1997/98 and 2005 episodes were recorded about 3 months of negative anomalies of discharge, while in 2010, there were about 4 months of negative anomalies during the low water period. According to the data obtained from the Civil Defense, flood events would be more impactful to the local community than the drought ones. However, the absence of quantitative indicators hinders a more precise analysis of the real impacts of drought and flood events in the region. In fact, during the dry season two aspects of extreme importance need to be better addressed: i) the fact that the population of one of the wettest regions of the planet does not have a good water supply for human being, and ii) what are the impacts of extreme drought on the cycle of reproduction of species of local fish fauna?

    Full Text Available This paper examines the effect of international and domestic factors on the sovereign bond spreads for 22 developed countries in North America, Europe and Pacific Rim regions. First, for all the regions the impact of global factors on the sovereign bond spreads is more intense than regional factors. Second, the findings confirm that for the bond spreads of each region over its domestic government bonds, the countries’ local fundamentals are better determinants of the spreads compared to the spread over US government bonds as a safe haven. Third, the influence of worldwide factors in the Eurozone compared to other regions bond spreads is less. Fourth, the relationship of the market sentiment and the investor risk aversion with the sovereign bond spreads of all regions is positive. Equity market volatility plays significant role in yield speads in international bond markets.

    Purpose: To review the risk of local recurrence and impact of salvage therapy after Watch and Wait for rectal cancer with complete clinical response (cCR) after chemoradiation therapy (CRT). Methods and Materials: Patients with cT2-4N0-2M0 distal rectal cancer treated with CRT (50.4-54 Gy + 5-fluorouracil-based chemotherapy) and cCR at 8 weeks were included. Patients with cCR were enrolled in a strict follow-up program with no immediate surgery (Watch and Wait). Local recurrence-free survival was compared while taking into account Watch and Wait strategy alone and Watch and Wait plus salvage. Results: 90 of 183 patients experienced cCR at initial assessment after CRT (49%). When early tumor regrowths (up to and including the initial 12 months of follow-up) and late recurrences were considered together, 28 patients (31%) experienced local recurrence (median follow-up time, 60 months). Of those, 26 patients underwent salvage therapy, and 2 patients were not amenable to salvage. In 4 patients, local re-recurrence developed after Watch and Wait plus salvage. The overall salvage rate for local recurrence was 93%. Local recurrence-free survival at 5 years was 69% (all local recurrences) and 94% (after salvage procedures). Thirteen patients (14%) experienced systemic recurrence. The 5-year cancer-specific overall survival and disease-free survival for all patients (including all recurrences) were 91% and 68%, respectively. Conclusions: Local recurrence may develop in 31% of patients with initial cCR when early regrowths (≤12 months) and late recurrences are grouped together. More than half of these recurrences develop within 12 months of follow-up. Salvage therapy is possible in ≥90% of recurrences, leading to 94% local disease control, with 78% organ preservation

    Full Text Available Global warming which leads to climate change has potential affect to Indonesia agriculture activities and production. Analyzing rainfall pattern and distribution is important to investigate the impact of global climate change to local climate. This study using rainfall data from 1976-2010 from both lowland and upland area of Lampung Province. The results show that rainfall tends to decrease since the 1990s which related to the years with El Nino event. Monsoonal pattern- having rain and dry season- still excist in Lampung; however, since most rain fell below the average, it could not meet crops water need. Farmers conclude that dry seasons were longer and seasonal pattern has been changed. Global climate change might affect Lampung rainfall distribution through changes on sea surface temperature which could intensify the El Nino effect. Therefore, watching the El Nino phenomena and how global warming affects it, is important in predicting local climate especially the rainfall distribution in order to prevent significant loss in agriculture productivities.

    Climatic conditions influence the culture and economy of societies and the performance of economies. Specifically, El Niño as an extreme climate event is known to have notable effects on health, agriculture, industry, and conflict. Here, we construct directed and weighted climate networks based on near-surface air temperature to investigate the global impacts of El Niño and La Niña. We find that regions that are characterized by higher positive/negative network “in”-weighted links are exhibiting stronger correlations with the El Niño basin and are warmer/cooler during El Niño/La Niña periods. In contrast to non-El Niño periods, these stronger in-weighted activities are found to be concentrated in very localized areas, whereas a large fraction of the globe is not influenced by the events. The regions of localized activity vary from one El Niño (La Niña) event to another; still, some El Niño (La Niña) events are more similar to each other. We quantify this similarity using network community structure. The results and methodology reported here may be used to improve the understanding and prediction of El Niño/La Niña events and also may be applied in the investigation of other climate variables.

    It has been challenging for microneedles to deliver drugs effectively to thin tissues with little background support such as the cornea. Herein, we designed a microneedle pen system, a single microneedle with a spring-loaded microneedle applicator to provide impact insertion. To firmly attach solid microneedles with 140 μm in height at the end of macro-scale applicators, a transfer molding process was employed. The fabricated microneedle pens were then applied to mouse corneas. The microneedle pens successfully delivered rhodamine dye deep enough to reach the stromal layer of the cornea with small entry only about 1000 μm(2). When compared with syringes or 30 G needle tips, microneedle pens could achieve more localized and minimally invasive delivery without any chances of perforation. To investigate the efficacy of microneedle pens as a way of drug delivery, sunitinib malate proven to inhibit in vitro angiogenesis, was delivered to suture-induced angiogenesis model. When compared with delivery by a 30 G needle tip dipped with sunitinib malate, only delivery by microneedle pens could effectively inhibit corneal neovascularization in vivo. Microneedle pens could effectively deliver drugs to thin tissues without impairing merits of using microneedles: localized and minimally invasive delivery. Copyright © 2015 Elsevier B.V.

    The role of adrenal vein sampling (AVS) has been debated, with some authorities advocating selective use in younger patients (≤40 years), and those localized by preoperative imaging. We examined our experience to determine the impact of AVS in patients who routinely underwent AVS with a high success rate. A retrospective cohort study was performed using a prospectively maintained database of patients referred for evaluation of PA (1997-2013). Patients were classified as localized (L) if a unilateral mass was identified on imaging, and non-localized (NL) otherwise. Of 367 patients, 94% (n = 345) underwent successful AVS. Seventy-two percent (n = 265) were L; AVS was lateralizing 58% (n = 214). AVS changed management in 43% of patients (n = 158). In patients ≤40 years, AVS changed management in 30% (n = 15). In patients ≤40 years with a ≥1 cm adrenal mass, 12% (n = 3) would have undergone unnecessary surgery based on imaging results alone; in patients >40 years with a ≥1 cm adrenal mass, 3% (n = 5) would have undergone wrong-side surgery, and 30% (n = 50) would have undergone unnecessary surgery based on imaging. AVS changed management in a significant minority of patients regardless of age and imaging findings. AVS should be routinely recommended in all patients with PA, to direct operative therapy. J. Surg.

    We demonstrate that the occurrence of Edge-Localized-Modes (ELM) crashes does not depend only on the linear peeling-ballooning threshold, but also relies on nonlinear processes. Wave-wave interaction constrains the growth time of a mode, thus inducing a shift in the criterion for triggering an ELM crash. An ELM crash requires the P-B growth rate to exceed a critical value γ>γ{sub c}, where γ{sub c} is set by 1/τ{sup ¯}{sub c}, and τ{sup ¯}{sub c} is the averaged mode phase coherence time. For 0<γ<γ{sub c}, P-B turbulence develops but drives enhanced turbulent transport. We also show that electron inertia dramatically changes the instability threshold when density is low. However, P-B turbulence alone cannot generate enough current transport to allow fast reconnection during an ELM crash.

    Industrial pollution can provide a useful tool to study spatiotemporal distribution of modern floodplain sediments, trace their provenance, and allow their dating. Regional contamination of southern Moravia (the south-eastern part of the Czech Republic) by heavy metals during the 20th century was determined in fluvial sediments of the Morava River by means of enrichment factors. The influence of local sources and sampling sites heterogeneity were studied in overbank fines with different lithology and facies. For this purpose, samples were obtained from hand-drilled cores from regulated channel banks, with well-defined local sources of contamination (factories in Zlín and Otrokovice) and also from near naturally inundated floodplains in two nature protected areas (at 30 km distance). The analyses were performed by X-ray fluorescence spectroscopy (ED XRF), ICP MS (EDXRF samples calibration, 206Pb/207Pb ratio), magnetic susceptibility, cation exchange capacity (CEC), and 137Cs and 210Pb activities. Enrichment factors (EF) of heavy metals (Pb, Zn, Cu and Cr) and magnetic susceptibility of overbank fines in near-naturally (near annually) inundated areas allowed us to reconstruct historical contamination by heavy metals in the entire study area independently on lithofacies. Measured lithological background values were then used for calculation of EFs in the channel sediments and in floodplain sediments deposited within narrow part of a former floodplain which is now reduced to about one quarter of its original width by flood defences. Sediments from regulated channel banks were found stratigraphically and lithologically "erratic", unreliable for quantification of regional contamination due to a high variability of sedimentary environment. On the other hand, these sediments are very sensitive to the nearby local sources of heavy metals.

    Climate change is of critical concern for conservation and to develop appropriate policies and responses, it is important not only to anticipate the nature of changes, but also how they are perceived, interpreted and adapted to by local people. The Albertine Rift in East Africa is one of the most threatened biodiversity hotspots due to dense settlement, extreme poverty, and land conversion. We synthesize ongoing NSF-CNH research, where Ugandan park landscapes are examined to understand the impacts of climate change on livelihoods. Kibale National Park, the main study site, exemplifies the challenges facing many parks because of its isolation within a densely populated agricultural landscape. Three separate household surveys (n=251, 130, 100) reveal that the most perceived benefits provided by Kibale were ecosystem services and farmers cite rainfall as one of the park's most important benefits, but are also concerned with variable precipitation. Analysis of 30+ years of daily rainfall station data shows total rainfall has not changed significantly, but timing and transitions of seasons and intra-seasonal distribution are highly variable, which may contribute to changes in farming schedules and threaten food security. Further, the contrast between land use/cover change over 25 years around the park and the stability of forest within the park underscores the need to understand this landscape for future sustainability planning and the inevitable population growth outside its boundaries. Understanding climate change impacts and feedbacks to and from socio-ecological systems are important to address the dual challenge of biodiversity conservation and poverty alleviation.

    Full Text Available Whereas past research studied the impact of online reviews on a hotel’s image, the present study analyzes the impact of various measures of customer engagement on the local market ranking of a hotel. For these purposes, the researchers collected data on a sample of hotels including the number of reviews, absolute rating (i.e. 1-5 stars, and market ranking (i.e. 1st, 2nd, 3rd place on TripAdvisor. The authors tested the relationships between number of reviews, market ranking, overall rating and number of booking transactions. Results revealed that the absolute rating of the hotel was a significant factor in determining its market ranking, whereas other elements such as the number of reviews were not. Since the logarithm used by TripAdvisor and other review sites is of a proprietary nature, research that illuminates the relationships between overall rating, market ranking, and number of reviews, helps illuminate scholar’s and practitioner’s understanding of how to improve hotel performance and online image.

    We use 3 yr of surface absolute gravity measurements at three sites on the Larzac plateau (France) to quantify the changes induced by topography and the building on gravity time-series, with respect to an idealized infinite slab approximation. Indeed, local topography and buildings housing ground-based gravity measurement have an effect on the distribution of water storage changes, therefore affecting the associated gravity signal. We first calculate the effects of surrounding topography and building dimensions on the gravity attraction for a uniform layer of water. We show that a gravimetric interpretation of water storage change using an infinite slab, the so-called Bouguer approximation, is generally not suitable. We propose to split the time varying gravity signal in two parts (1) a surface component including topographic and building effects (2) a deep component associated to underground water transfer. A reservoir modelling scheme is herein presented to remove the local site effects and to invert for the effective hydrological properties of the unsaturated zone. We show that effective time constants associated to water transfer vary greatly from site to site. We propose that our modelling scheme can be used to correct for the local site effects on gravity at any site presenting a departure from a flat topography. Depending on sites, the corrected signal can exceed measured values by 5-15 μGal, corresponding to 120-380 mm of water using the Bouguer slab formula. Our approach only requires the knowledge of daily precipitation corrected for evapotranspiration. Therefore, it can be a useful tool to correct any kind of gravimetric time-series data.

    Many measurements in cosmology depend on the use of integrated distances or time, but galaxies evolving passively on a timescale much longer than their age difference allow us to determine the expansion rate H ( z ) solely as a function of the redshift–time derivative dz / dt . These model-independent “cosmic chronometers” can therefore be powerful discriminators for testing different cosmologies. In previous applications, the available sources strongly disfavored models (such as ΛCDM) predicting a variable acceleration, preferring instead a steady expansion rate over the redshift range 0 ≲ z ≲ 2. A more recent catalog of 30 objects appears to suggest non-steady expansion. In this paper, we show that such a result is entirely due to the inclusion of a high, locally inferred value of the Hubble constant H{sub 0} as an additional datum in a set of otherwise pure cosmic-chronometer measurements. This H {sub 0}, however, is not the same as the background Hubble constant if the local expansion rate is influenced by a Hubble Bubble. Used on their own, the cosmic chronometers completely reverse this conclusion, favoring instead a constant expansion rate out to z∼2.

  4. Value/impact of design criteria for cast ductile iron shipping casks

    International Nuclear Information System (INIS)

    1983-01-01

    The ductile failure criteria proposed in the Base report appear appropriate except that stress intensity values, S/sub m/ should be based on lower safety factors and ductility should be added as a criterion. A safety factor for stress intensity, s/sub m/ of 4 is recommended rather than 3 on minimum ultimate tensile strength, S/sub u/ in accordance with ASME code philosophy of assigning higher safety factors to cast ductile iron than to steel. This more conservative approach has no impact on costs since the selection of wall thickness is controlled by shielding rather than by stress considerations. The addition of a ductility criterion is recommended because of the problems associated with the selection of appropriate brittle failure criteria and the potential for cast ductile iron to have extremely low elongation at failure. Neither a materials nor a linear elastic fracture mechanics (LEFM) approach appear to be viable for demonstrating the prevention of brittle failure in cast ductile iron shipping casks. It is possible that the analytic methods predict brittle failure because of extremely conservative assumptions whereas real casks may not fail. Model drop tests could be used to demonstrate containment integrity. It is estimated that a risk committment of at least $1,000,000 would be required for engineering, design, model fabrication and testing. Before taking such risks, a mechanism should be found to obtain concurrence from NRC that the results of the test would be acceptable. Probabilistic approaches or model testing could be used to demonstrate the acceptability of cast ductile iron casks from a brittle failure point of view. Before probabilistic methods can be used, the NRC would have to be persuaded to accept the approach of the Competent Authority in West Germany or more formalized methods for probabilistic risk assessments

    Research highlights: → Experimental series on UHPC panels subjected to aircraft engine impact. → Improved ballistic limit of fiber reinforced UHPC in comparison to conventional R/C. → Detailed investigation of failure mechanisms of fiber reinforced UHPC panel. - Abstract: The impact of an aircraft engine missile causes high stresses, deformations and a severe local damage to conventional reinforced concrete. As a consequence the design of R/C protective structural elements results in components with rather large dimensions. Fiber reinforced Ultra High Performance Concrete (UHPC) is a concrete based material which combines ultra high strength, high packing density and an improved ductility with a significantly increased energy dissipation capacity due to the addition of fiber reinforcement. With those attributes the material is potentially suitable for improved protective structural elements with a reduced need for material resources. The presented paper reports on an experimental series of scaled aircraft engine impact tests with reinforced UHPC panels. The investigations are focused on the material behavior and the damage intensity in comparison to conventional concrete. The fundamental work of is taken as reference for the evaluation of the results. The impactor model of a Phantom F4 GE-J79 engine developed and validated by Sugano et al. is used as defined in the original work. In order to achieve best comparability, the experimental configuration and method are adapted for the UHPC experiments. With 'penetration', 'scabbing' and 'perforation' all relevant damage modes defined in are investigated so that a full set of results are provided for a representative UHPC structural configuration.

  7. Local resources, foreign influences, value creation, tradition and modernity. The case of a Local Agro-food System in Jämtland, Sweden

    2016-06-01

    Full Text Available During the 1980’s collective action was initiated with the purpose of saving the remnants of traditional livestock farming in Jämtland. This led to the articulation of a local agro-food system (LAFS that managed to commercialize important elements of traditional agriculture by adding elements of modernity. Farm diversification was an important strategy that led to the forward integration of farms that includes the start of small scale farm dairies, farm cafes, direct sales, at the farm, through markets and other local channels, B&Bs and outdoor tourism operations. In the mentioned process, foreign knowledge and experience led to the opening of a new market for traditional products. This case shows that the localization and appropriation of foreign elements can be a fruitful strategy to promote territorial development in regions like Jämtland. This article highlights how a LAFS was articulated within the frame of the birth of a new industry, composed by small, semi-artisan dairy firms and which institutional side effects that this experience has led to.Durante la década de los 80, un proceso de acción colectiva se inició con el propósito de salvar los restos de la ganadería tradicional en Jämtland. Esto resultó en la creación de un sistema agroalimentario local que logró comercializar elementos importantes de la agricultura tradicional, añadiendo elementos de modernidad. La diversificación de las fincas fue la estrategia más importante, dentro de la cual se promovió la creación de un sector de pequeñas industrias lácteas en las fincas, cafés rurales y asimismo la venta directa a los consumidores en dichas fincas, en mercados y otros canales de comercialización, servicios de alojamiento y desayuno y operaciones turísticas al aire libre. En este proceso, conocimiento y experiencias extranjeras jugaron un papel clave en la apertura de un nuevo mercado para los productos lácteos tradicionales. Este caso demuestra que la

    We construct ℓ -spin-flipping matrices from the coefficient matrices of pure states of n qubits and show that the ℓ -spin-flipping matrices are congruent and unitary congruent whenever two pure states of n qubits are SLOCC and LU equivalent, respectively. The congruence implies the invariance of ranks of the ℓ -spin-flipping matrices under SLOCC and then permits a reduction of SLOCC classification of n qubits to calculation of ranks of the ℓ -spin-flipping matrices. The unitary congruence implies the invariance of singular values of the ℓ -spin-flipping matrices under LU and then permits a reduction of LU classification of n qubits to calculation of singular values of the ℓ -spin-flipping matrices. Furthermore, we show that the invariance of singular values of the ℓ -spin-flipping matrices Ω 1^{(n)} implies the invariance of the concurrence for even n qubits and the invariance of the n-tangle for odd n qubits. Thus, the concurrence and the n-tangle can be used for LU classification and computing the concurrence and the n-tangle only performs additions and multiplications of coefficients of states.

    threshold values of indices useful to determine the end of the potential fire season due to fuel status. A weather generator linked to climate change scenarios derived from 17 available General Circulation Models (GCMs) was used to produce synthetic weather series, representing present and future climates, for four selected sites located in North Sardinia, Italy. Finally, impacts of future climate change on fire season length at local scale were simulated. Results confirmed that the projected climate scenarios over the Mediterranean area will determine an overall increase of the fire season length.

    2012-01-01

    Purpose: This study examines the management and outcomes of muscle-invasive bladder cancer in the United States. Methods and Materials: Patients with muscle-invasive bladder cancer diagnosed between 1988 and 2006 were identified in the Surveillance, Epidemiology, and End Results (SEER) database. Patients were classified according to three mutually exclusive treatment categories based on the primary initial treatment: no local management, radiotherapy, or surgery. Overall survival was assessed with Kaplan-Meier analysis and Cox models based on multiple factors including treatment utilization patterns. Results: The study population consisted of 26,851 patients. Age, sex, race, tumor grade, histology, and geographic location were associated with differences in treatment (all p < 0.01). Patients receiving definitive radiotherapy tended to be older and have less differentiated tumors than patients undergoing surgery (RT, median age 78 years old and 90.6% grade 3/4 tumors; surgery, median age 71 years old and 77.1% grade 3/4 tumors). No large shifts in treatment were seen over time, with most patients managed with surgical resection (86.3% for overall study population). Significant survival differences were observed according to initial treatment: median survival, 14 months with no definitive local treatment; 17 months with radiotherapy; and 43 months for surgery. On multivariate analysis, differences in local utilization rates of definitive radiotherapy did not demonstrate a significant effect on overall survival (hazard ratio, 1.002; 95% confidence interval, 0.999–1.005). Conclusions: Multiple factors influence the initial treatment strategy for muscle-invasive bladder cancer, but definitive radiotherapy continues to be used infrequently. Although patients who undergo surgery fare better, a multivariable model that accounted for patient and tumor characteristics found no survival detriment to the utilization of definitive radiotherapy. These results support continued

    Full Text Available Consumer’s values, Cultural values, Emotional Values and Word of mouth expressiveness, are good predictors for their buying decision satisfaction. In current study sample of 500 was taken to assess the consumer’s buying decision satisfaction in relation to the importance of their values associated with those decisions. This study also reveals how gender influences buying decision satisfaction. Consumer values have a positive and significant impact on buying decision satisfac-tion. While evaluation on the basis of gender and females have more emotional and word of mouth linkages than males, on the contrary to this, males are more concerned with cultural val-ues, and are less expressive and have a tendency to suppress their emotions while making buy-ing decisions.

    The impact of product information and repeated exposure of local apple juice on consumer liking, sensory perception and concept associations was studied. Findings showed that consumers had high expectations towards the studied local apples juices. Consequently, the liking for the local apple juices...... did not fully determine consumer liking. Thus the sensory characteristics were also found to be of importance. Besides liking, the concept associations were also affected by product information. All local apple juices were associated as being more exclusive under informed tasting conditions....... No effects were found for liking of the apple juices over repeated exposure. Also, the consumers did not change their sensory perception over repeated consumption. However, the local apple juices were conceptualised as more familiar but remained exclusive after repeated consumption. When local producers have...

    Dramatic changes in the global distribution of emissions over the last decade have fundamentally altered source-receptor pollution impacts. A new generation of low-earth orbiting (LEO) sounders complimented by geostationary sounders over North America, Europe, and Asia providing a unique opportunity to quantify the current and future trajectory of emissions and their impact on global pollution. We examine the potential of this constellation of air quality sounders to quantify the role of local and non-local sources of pollution on background ozone in the US. Based upon an adjoint sensitivity method, we quantify the role synoptic scale transport of non-US pollution on US background ozone over months representative of different source-receptor relationships. This analysis allows us distinguish emission trajectories from megacities, e.g. Beijing, or regions, e.g., western China, from natural trends on downwind ozone. We subsequently explore how a combination of LEO and GEO observations could help quantify the balance of local emissions against changes in distant sources . These results show how this unprecedented new international ozone observing system can monitor the changing structure of emissions and their impact on global pollution.

  18. Assessing Covariation of Holocene Monsoon Intensity and Local Moisture Conditions in Eastern and Southwestern Amazon Basin Using Speleothem δ18O and 87Sr/86Sr Values

    δ18O records from South America offer insight into past variability of the South American Monsoon System (SAMS). Potential, however, for understanding local moisture conditions is limited as precipitation δ18O is strongly influenced by regional climate dynamics. Here we create Holocene speleothem 87Sr/86Sr records at 200-yr resolution using TIMS methods in the Center for Isotope Geochemistry at Boston College to complement existing Holocene δ18O speleothem records and investigate local moisture conditions above caves located in the eastern Amazon Basin (PAR - 4°S, 55°W) and southwestern Brazil (JAR - 21°S, 56°W). Speleothem 87Sr/86Sr variability is interpreted to reflect differences in the extent of water-rock interaction due to differences in infiltration rates under wet and dry conditions. Drier conditions promote longer residence time, enhanced water-rock interaction, and greater evolution of dripwater 87Sr/86Sr values from an initial isotopic signature acquired from the soil to the signature of the cave host rock. PAR speleothem 87Sr/86Sr values range from 0.71024 to 0.71067 and are bracketed by soil (0.71710 to 0.70956) and bedrock (0.70852 to 0.70899) values. JAR speleothem 87Sr/86Sr values range from 0.71216 to 0.71539 and are greater than bedrock values (0.70825 to 0.71219), although some speleothem values exceed the single analysis conducted of the soil isotopic composition (0.71473). JAR speleothem 87Sr/86Sr values increase from the early to mid Holocene, consistent with increase in local moisture availability associated with intensification of the SAMS suggested by decreasing δ18O values in many records from the region. Speleothem 87Sr/86Sr values at JAR decrease from the mid to late Holocene, consistent with an increase in δ18O values at PAR that suggest a decline in monsoon intensity. 87Sr/86Sr variability at JAR, however, is positively correlated with the δ18O record. Preliminary 87Sr/86Sr results from PAR are only broadly consistent with

    In this article, we define value in the context of reimbursement and explore the effect of shifting reimbursement paradigms on the decision-making autonomy of a women's imaging radiologist. The current metrics used for value-based reimbursement such as report turnaround time are surrogate measures that do not measure value directly. The true measure of a physician's value in medicine is accomplishment of better health outcomes, which, in breast imaging, are best achieved with a physician-patient relationship. Complying with evidence-based medicine, which includes data-driven best clinical practices, a physician's clinical expertise, and the patient's values, will improve our science and preserve the art of medicine.
