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.

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

The societal impact value of risk

International Nuclear Information System (INIS)

Simpson, D.E.

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

Examining the economic impacts of hydropower dams on property values using GIS.

Science.gov (United States)

Bohlen, Curtis; Lewis, Lynne Y

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

Technology overview: assessment of social values in thermal power plant siting, social impact methodology evaluation

International Nuclear Information System (INIS)

Anon.

1978-01-01

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

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

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 Indonesia is a nation with cultural diversity and area. This caused a lot of the uniqueness of culture in everyday life. 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. 

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

Impact of localized microwave hyperthermia on the pH-distribution in malignant tumors

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

Impact of 'stretch' targets for cardiovascular disease management within a local pay-for-performance programme.

2015-01-01

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.

LCA of contaminated site remediation - integration of site-specific impact assessment of local toxic impacts

DEFF Research Database (Denmark)

Lemming, Gitte; Hauschild, Michael Zwicky; Chambon, Julie Claire Claudia

2011-01-01

impacts have typically been assessed using site-generic characterization models representing a continental scale and excluding the groundwater compartment. Soil contaminants have therefore generally been assigned as emissions to surface soil or surface water compartments. However, such site-generic...... assessments poorly reflect the fate of frequent soil contaminants such as chloroethenes as they exclude the groundwater compartment and assume that the main part escapes to the atmosphere. Another important limitation of the generic impact assessment models is that they do not include the formation......The environmental impacts from remediation can be divided into primary and secondary impacts. Primary impacts cover the local impacts associated with the on-site contamination, whereas the secondary impacts are impacts on the local, regional and global scale generated by the remediation activities...

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)

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.

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.

Typography And Local Culture How Local Values Influence Batik Label Design In Yogyakarta And Surakarta

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.

Handbook for value-impact assessments of NRC regulatory actions

International Nuclear Information System (INIS)

Mullen, M.F.; DiPalo, A.J.

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

Damage diagnostic of localized impact erosion by measuring acoustic vibration

International Nuclear Information System (INIS)

Futakawa, Masatoshi; Kogawa, Hiroyuki; Ikeda, Yujiro

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)

The local impacts of nuclear stations

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.

Local behavior of reinforced concrete slabs to aircraft engine projectile impact

International Nuclear Information System (INIS)

Yoo, Hyeon Kyeong; Choi, Hyun; Chung, Chul Hun; Lee, Jung Whee; Kim, Sang Yun

2011-01-01

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

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

Local Residents’ Perceptions of Socio-Cultural Impacts of Tourism in Mangochi, Malawi

Felix G. BELLO

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.

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

Seizure semiology: its value and limitations in localizing the epileptogenic zone.

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.

It is unclear why rates of homelessness claims in England have risen since 2010. We used variations in rates across local authorities to test the impact of economic downturns and budget cuts. Using cross-area fixed effects models of data from 323 UK local authorities between 2004 and 2012, we evaluated associations of changes in statutory homelessness rates with economic activity (Gross Value Added per capita), unemployment, and local and central government expenditure.

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

International Nuclear Information System (INIS)

Romano, Antonio Enea; Chen, Pisin

2011-01-01

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

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.

Economic value of U.S. fossil fuel electricity health impacts.

Science.gov (United States)

Machol, Ben; Rizk, Sarah

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.

From global framing to local action : translation of climate change impacts in Africa

Energy Technology Data Exchange (ETDEWEB)

Ogunseitan, O.A. [Harvard Univ., Cambridge, MA (United States)

2000-06-01

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.

Steepest descent method for set-valued locally accretive mappings

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

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

1986-01-01

This paper presents an extended value-impact methodology with aids decision makers in ranking various alternative actions for reducing the risk associated with nuclear power reactors. 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.)

A preliminary study on the local impact behavior of Steel-plate Concrete walls

Kim, Kap-sun; Moon, Il-hwan; Choi, Hyung-jin; Nam, Deok-woo

2017-01-01

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.

A look at local economic impacts

International Nuclear Information System (INIS)

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

A value/impact assessment for alternative decay heat removal systems

Cave, L.; Kastenberg, W.E.; Lin, K.Y.

1984-01-01

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.)

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

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.

The Brazilian Seed Law and its impacts on agrobiodiversity and on local and traditional agricultural systems

Juliana Santilli

2012-08-01

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.

Industrial development and its impact on land values

O'Ferrall, B.K.

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

Recent Trends in Local-Scale Marine Biodiversity Reflect Community Structure and Human Impacts.

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.

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

International Nuclear Information System (INIS)

Thorhallsdottir, Thora Ellen

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

Impact localization on composite structures using time difference and MUSIC approach

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.

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.

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

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

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

Local Impact Simulation of SC Wall Structures using Aircraft Engine Projectile

International Nuclear Information System (INIS)

Chung, Chulhun; Lee, Jungwhee; Lee, Hanjoo; Jung, Raeyoung; Hyun, Changhun

2013-01-01

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

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.

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

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

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

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

Science.gov (United States)

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

Should Social Value Obligations be Local or Global?

Science.gov (United States)

Nayak, Rahul; Shah, Seema K

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.

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.

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

Science.gov (United States)

Qiu, Lei; Yuan, Shenfang; Mei, Hanfei; Qian, Weifeng

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

Economic and social impact of modernization on cultural values

Elena Andreeva

2017-05-01

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.

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

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.

Value-impact assessment of safety-related modifications

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

A fast direct solver for boundary value problems on locally perturbed geometries

Science.gov (United States)

Zhang, Yabin; Gillman, Adrianna

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.

Gender differences in personal values of national and local Italian politicians, activists and voters.

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.

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

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.

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

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.

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.

2017-10-01

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.

Exploring local perceptions and attributions of 'extreme' wildfire impacts in Rural Montana

Carroll, M.; Paveglio, T.; Kallman, D.

2013-12-01

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

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

International Nuclear Information System (INIS)

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

2011-01-01

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

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.)

The Impact of Domestic Gastronomic Festivals on the Local Accomodations

2015-10-01

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.

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

Delphine B. H. Chabanne

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.

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.

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.

Holography of Wilson-loop expectation values with local operator insertions

Miwa, Akitsugu; Yoneya, Tamiaki

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

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.

Background: Health Impact Assessment (HIA) in Ireland has developed significantly since its endorsement in the health strategies of the Republic of Ireland (2001) and Northern Ireland (2002). Throughout 2007 and 2008, research was conducted to examine HIA as a policy-informing tool throughout both jurisdictions. One aspect of this research investigated the role of local government and its relationship in advancing HIA practise and use in Ireland. Methods: A case study research design was used which employed qualitative research methods, including semistructured interviewing and participant observation. In total 48 interviews were conducted with members of the HIA steering committees and individuals closely involved in the HIAs. Results: The relationship between local government and HIA in Northern Ireland is a positive one given the strong tradition of local government in the jurisdiction.

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

Science.gov (United States)

Rolph, R.; Mahoney, A. R.

2015-12-01

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

Valuing Health Using Time Trade-Off and Discrete Choice Experiment Methods: Does Dimension Order Impact on Health State Values?

Science.gov (United States)

Mulhern, Brendan; Shah, Koonal; Janssen, Mathieu F Bas; Longworth, Louise; Ibbotson, Rachel

2016-01-01

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.

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

International Nuclear Information System (INIS)

Catena, Riccardo; Ullio, Piero

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

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.

Local impact effects on concrete target due to missile: An empirical and numerical approach

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

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.

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.

Impact Localization Method for Composite Plate Based on Low Sampling Rate Embedded Fiber Bragg Grating Sensors

Directory of Open Access Journals (Sweden)

Zhuo Pang

2017-01-01

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.

The impact of worker values on client outcomes within a drug treatment service.

Phillips, Rosie; Bourne, Humphrey

2008-02-01

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.

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.)

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.

Kost, Christoph; Engelken, Maximilian; Schlegl, Thomas

2012-01-01

This paper discusses the value generation potential for local and international industry in different development scenarios of the concentrating solar power (CSP) market in North Africa until 2030. It analyzes the economic impact resulting from the participation of North African and European companies during construction and operation of CSP plants. The assessment is based on a self-developed solar technologies market development model (STMD) that includes economic and technical requirements and constraints for the creation of a local CSP market. In-depth interviews with industry stakeholders provide specific input, validate the calculations and complement the quantitative model results and conclusions. Long-term potential for locally generated revenues from CSP plant construction are modeled and lead to a share of local revenues of up to 60%. Potential market size of solar power plants in North Africa could reach total revenues of 120 Billion euros and thus demand for components and services contribute to national gross domestic products significantly. Recommendations are given for regional industry cooperation and policy actions for the support of local and international CSP industry in North Africa in order to improve the investment environment and growth of renewable energies in the region. - Highlights: ►New economic model to evaluate value generation of CSP take-off in North Africa. ►CSP components are assessed regarding their potentials to be produced locally. ►Potential for locally generated revenues of CSP plants: 60% of total value. ►Socio-economic impacts of RE projects become more relevant to investment decisions.

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.

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

International Nuclear Information System (INIS)

Yuan, Shenfang; Bao, Qiao; Qiu, Lei; Zhong, Yongteng

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)

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

Directory of Open Access Journals (Sweden)

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

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.

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

Directory of Open Access Journals (Sweden)

Christopher Ettmayr

2017-08-01

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

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.

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.

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

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

International Nuclear Information System (INIS)

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

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.

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.

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.

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.

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

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.

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.

The impact of vehicle on the relative potency of skin-sensitizing chemicals in the local lymph node assay.

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.

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

OpenAIRE

Chipman, A.; Morrison, E.

2013-01-01

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...

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

International Nuclear Information System (INIS)

Mancarella, Pierluigi; Chicco, Gianfranco

2009-01-01

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 . Two case study applications based on the emission

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.

Determining perception-based impacts of noxious facilities on wage rates and property values

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.

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

Energy Technology Data Exchange (ETDEWEB)

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.

Water impacts and water-climate goal conflicts of local energy choices - notes from a Swedish perspective

Science.gov (United States)

Ericsdotter Engström, Rebecka; Howells, Mark; Destouni, Georgia

2018-02-01

To meet both the Paris Agreement on Climate Change and the UN Sustainable Development Goals (SDGs), nations, sectors, counties and cities need to move towards a sustainable energy system in the next couple of decades. Such energy system transformations will impact water resources to varying extents, depending on the transformation strategy and fuel choices. Sweden is considered to be one of the most advanced countries towards meeting the SDGs. This paper explores the geographical origin of and the current water use associated with the supply of energy in the 21 regional counties of Sweden. These energy-related uses of water represent indirect, but still relevant, impacts for water management and the related SDG on clean water and sanitation (SDG 6). These indirect water impacts are here quantified and compared to reported quantifications of direct local water use, as well as to reported greenhouse gas (GHG) emissions, as one example of other types of environmental impacts of local energy choices in each county. For each county, an accounting model is set up based on data for the local energy use in year 2010, and the specific geographical origins and water use associated with these locally used energy carriers (fuels, heat and electricity) are further estimated and mapped based on data reported in the literature and open databases. Results show that most of the water use associated with the local Swedish energy use occurs outside of Sweden. Counties with large shares of liquid biofuel exhibit the largest associated indirect water use in regions outside of Sweden. This indirect water use for energy supply does not unambiguously correlate with either the local direct water use or the local GHG emissions, although for the latter, there is a tendency towards an inverse relation. Overall, the results imply that actions for mitigation of climate change by local energy choices may significantly affect water resources elsewhere. Swedish counties are thus important examples

Modeling of Local BEAM Structure for Evaluation of MMOD Impacts to Support Development of a Health Monitoring System

Science.gov (United States)

Lyle, Karen H.; Vassilakos, Gregory J.

2015-01-01

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.

Impact of local and non-local sources of pollution on background US Ozone: synergy of a low-earth orbiting and geostationary sounder constellation

Science.gov (United States)

Bowman, K. W.; Lee, M.

2015-12-01

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.

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{sub 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 < 0.4). In the patients with lung cancer, sphericity had prognostic 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

The impact of oil and natural gas facilities on rural residential property values

Boxall, P.C.

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

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

Science.gov (United States)

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.

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.

International trade of health services: global trends and local impact.

Science.gov (United States)

Lautier, Marc

2014-10-01

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.

Ethnicity and cultural values as predictors of the occurrence and impact of experienced workplace incivility.

Welbourne, Jennifer L; Gangadharan, Ashwini; Sariol, Ana M

2015-04-01

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).

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.

Full Text Available The places by the sea, as spaces of tourism and second homes, suffer the impacts from the activity. The local population attitude, seeing these places as bonuses or otherwise, as a burden, contributes to the viability of tourism in the locality. This article aims to present a research, methodologically related to attitude construct of social psychology, conducted in Laguna, Santa Catarina, Brazil to evaluate the relationship between the community and the different impacts caused by tourism,. Data collection, using an instrument originally proposed and validated by Molero and Cuadrado (2006, allowed the analysis to forward the position of residents on the effects of tourism in the place, evaluating eight impacts factors: environmental; delinquency; everyday life; perceived importance of tourism; public services and infrastructure; intercultural; employment; and values. The results indicate that most impacts are positive on younger residents, and in the environmental, crime and social values the impact is indifferent.

A one-dimensional model to describe flow localization in viscoplastic slender bars subjected to super critical impact velocities

Vaz-Romero, A.; Rodríguez-Martínez, J. A.

2018-01-01

In this paper we investigate flow localization in viscoplastic slender bars subjected to dynamic tension. We explore loading rates above the critical impact velocity: the wave initiated in the impacted end by the applied velocity is the trigger for the localization of plastic deformation. The problem has been addressed using two kinds of numerical simulations: (1) one-dimensional finite difference calculations and (2) axisymmetric finite element computations. The latter calculations have been used to validate the capacity of the finite difference model to describe plastic flow localization at high impact velocities. The finite difference model, which highlights due to its simplicity, allows to obtain insights into the role played by the strain rate and temperature sensitivities of the material in the process of dynamic flow localization. Specifically, we have shown that viscosity can stabilize the material behavior to the point of preventing the appearance of the critical impact velocity. This is a key outcome of our investigation, which, to the best of the authors' knowledge, has not been previously reported in the literature.

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.

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.

Modelling the Health Impact of an English Sugary Drinks Duty at National and Local Levels.

Directory of Open Access Journals (Sweden)

Brendan Collins

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.

2017-09-01

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.

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.

An Unexpected Means of Embedding Ethics in Organizations: Preliminary Findings from Values-Based Evaluations

Directory of Open Access Journals (Sweden)

Gemma Burford

2016-06-01

Full Text Available Ethical principles constitute a crucial area of debate and discussion in the global conversation around transitions to sustainability, and of particular relevance to the contribution of businesses and other organizations. Scholars in business ethics have recently identified several challenges in this area, such as problems of measurement, rigor, and meaningfulness to practitioners; corporate social responsibility; and institutionalization of ethics in businesses. In this paper, the impacts of a pragmatic values-based evaluation approach originally developed in another field—education for sustainable development—are shown to strongly contribute to many of these challenges. Impacts found across eight organizations include (i deep values conceptualization; (ii increased esteem (iii building capacity for assessment of values-based achievements; (iv values mainstreaming; and (v effective external values communications. It seems that the in-situ development and use of values-based indicators helped to conceptualize locally shared values that underpin decisions, thus embedding the application of (local ethics. Although this study is exploratory, it is clear that the values-based approach shows promise for meeting key challenges in business ethics and wider sustainability, and for new directions for future cross-disciplinary research.

Water impacts and water-climate goal conflicts of local energy choices – notes from a Swedish perspective

Directory of Open Access Journals (Sweden)

R. E. Engström

2018-02-01

Full Text Available To meet both the Paris Agreement on Climate Change and the UN Sustainable Development Goals (SDGs, nations, sectors, counties and cities need to move towards a sustainable energy system in the next couple of decades. Such energy system transformations will impact water resources to varying extents, depending on the transformation strategy and fuel choices. Sweden is considered to be one of the most advanced countries towards meeting the SDGs. This paper explores the geographical origin of and the current water use associated with the supply of energy in the 21 regional counties of Sweden. These energy-related uses of water represent indirect, but still relevant, impacts for water management and the related SDG on clean water and sanitation (SDG 6. These indirect water impacts are here quantified and compared to reported quantifications of direct local water use, as well as to reported greenhouse gas (GHG emissions, as one example of other types of environmental impacts of local energy choices in each county. For each county, an accounting model is set up based on data for the local energy use in year 2010, and the specific geographical origins and water use associated with these locally used energy carriers (fuels, heat and electricity are further estimated and mapped based on data reported in the literature and open databases. Results show that most of the water use associated with the local Swedish energy use occurs outside of Sweden. Counties with large shares of liquid biofuel exhibit the largest associated indirect water use in regions outside of Sweden. This indirect water use for energy supply does not unambiguously correlate with either the local direct water use or the local GHG emissions, although for the latter, there is a tendency towards an inverse relation. Overall, the results imply that actions for mitigation of climate change by local energy choices may significantly affect water resources elsewhere. Swedish counties are thus

Cost, energy, global warming, eutrophication and local human health impacts of community water and sanitation service options.

We compared water and sanitation system options for a coastal community across selected sustainability metrics, including environmental impact (i.e., life cycle eutrophication potential, energy consumption, and global warming potential), equivalent annual cost, and local human health impact. We computed normalized metric scores, which we used to discuss the options' strengths and weaknesses, and conducted sensitivity analysis of the scores to changes in variable and uncertain input parameters. The alternative systems, which combined centralized drinking water with sanitation services based on the concepts of energy and nutrient recovery as well as on-site water reuse, had reduced environmental and local human health impacts and costs than the conventional, centralized option. Of the selected sustainability metrics, the greatest advantages of the alternative community water systems (compared to the conventional system) were in terms of local human health impact and eutrophication potential, despite large, outstanding uncertainties. Of the alternative options, the systems with on-site water reuse and energy recovery technologies had the least local human health impact; however, the cost of these options was highly variable and the energy consumption was comparable to on-site alternatives without water reuse or energy recovery, due to on-site reuse treatment. Future work should aim to reduce the uncertainty in the energy recovery process and explore the health risks associated with less costly, on-site water treatment options.

The Impact of Transformational Leadership on Leader-Follower Work Value Congruence

Directory of Open Access Journals (Sweden)

David Bosch

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.

Decomposing cross-country differences in quality adjusted life expectancy: the impact of value sets.

2011-06-23

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

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.

Aim: To evaluate the impact of staging FDG PET-CT on the initial management of patients with locally advanced cervical carcinoma (LACC) and any prognostic variables predicting survival. Materials and methods: Retrospective analysis of consecutive patients undergoing FDG PET-CT for staging of LACC in a single tertiary referral centre, between April 2008 and August 2011. Comparison was made between MRI and PET-CT findings and any subsequent impact on treatment intent or radiotherapy planning was evaluated. Results: Sixty-three patients underwent FDG PET-CT for initial staging of LACC. Major impact on management was found in 20 patients (32%), a minor impact in five (8%), and no impact in 38 (60%). In those patients where PET-CT had a major impact, 12 had more extensive local nodal involvement, five had occult metastatic disease, two had synchronous tumours, and one patient had equivocal lymph nodes on MRI characterized as negative. PET-positive nodal status at diagnosis was found to be a statistically significant predictor of relapse-free survival (p < 0.05). Conclusion: Staging FDG PET-CT has a major impact on the initial management of approximately one-third of patients with LACC by altering treatment intent and/or radiotherapy planning. PET-defined nodal status is a poor prognostic indicator. - Highlights: • Cervical carcinoma is one of the commonest cancers in women worldwide. • Locally advanced cervical carcinoma is usually treated with chemo-radiotherapy. • FDG PET-CT can have a major impact on management in up to one-third of patients. • It may alter treatment intent or radiotherapy-planning by detecting occult disease. • PET nodal status at diagnosis is an important predictor of relapse-free survival

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

Science.gov (United States)

Taylor, Marylee C; Reyes, Adriana M

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.

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

Science.gov (United States)

Baltay, A.; Hanks, T. C.; Vernon, F.

2016-12-01

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.

Impact of Rice Paddy Areas Decrease on Local Climate over Taiwan

Science.gov (United States)

Lo, M. H.; Wen, W. H.; Chen, C. C.

2014-12-01

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.

Baumann, M.; Petersen, C.; Schulz, P.; Baisch, H.

1999-01-01

Background and purpose: The impact of overall treatment time of fractionated irradiation on local control of slow growing human GL squamous cell carcinoma (SCC) was determined. Materials and methods: Moderately well differentiated and keratinizing human GL SCC with a volume doubling time of 8 days were transplanted subcutaneously into the right hindleg of NMRI (nu/nu) mice and irradiated with 30 fractions under ambient conditions over 2, 3, 4.5, 6 and 10 weeks. Endpoint of the experiments was local tumor control at day 180 after end of treatment.Results: The tumor control dose 50% (TCD 50) increased from 40 to 57 Gy when the treatment time was extended from 2 to 10 weeks. The data can be well described by a linear increase in TCD 50 with time. The recovered dose per day (D r ) was 0.28 Gy (95% confidence interval 0.06; 0.48). The fit to the data was not significantly improved by assuming a biphasic (dog-leg) time course with constant TCD 50 values in the initial part of treatment followed by a more rapid increase of TCD 50 thereafter.Conclusions: D r in GL SCC was significantly less than the value of 1.0 Gy (0.7; 1.3 ) previously reported for poorly differentiated, non-keratinizing and fast growing human FaDu SCC (Baumann M, Liertz C, Baisch H, Wiegel T, Lorenzen J, Arps H. Impact of overall treatment time of fractionated irradiation on local control of human FaDu squamous cell carcinoma in nude mice. Radiother. Oncol. 1994;32:137-143), indicating important heterogeneity of the time factor between different tumors of the same histological type. (Copyright (c) 1999 Elsevier Science B.V., Amsterdam.

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.

2015-12-01

Full Text Available The likelihood of addressing the complex environmental, economic, and social/cultural issues associated with local climate change impacts is enhanced when collaborative partnerships with local people are established. Using a community-centered approach in the Teslin region of Canada’s Yukon Territory, we utilized our research skills to respond to local needs for information by facilitating both an internal community process to clarify traditional and local knowledge, values, and perceptions on locally identified priorities, while gathering external information to enable local people to make sound decisions. Specifically, we sought to clarify local perceptions surrounding climate change impacts on fire risk and wildlife habitat, and the potential adaptation strategies appropriate and feasible within the Teslin Tlingit Traditional Territory. This paper provides a characterization of the study region and our project team; provides background on the interview and data collection process; presents our key results; and discusses the importance of our findings and charts a way forward for our continued work with the people in the Teslin region. This approach presents an excellent opportunity to help people holistically connect a range of local values, including fire risk mitigation, habitat enhancement, economic development, and enhanced social health.

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

International Nuclear Information System (INIS)

Bjornstad, D.J.

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.

Excision margin status: does it impact on local control of breast cancer?

International Nuclear Information System (INIS)

Lamoury, G.; Morgan, G.; Ward, R.

2003-01-01

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

The economic impact of reduced value added tax rates for groceries

Directory of Open Access Journals (Sweden)

Slavomíra Martinková

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.

The health impact of tourism on local and indigenous populations in resource-poor countries.

Science.gov (United States)

Bauer, Irmgard

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.

Vertical integration of local fuel producers into rural district heating systems – Climate impact and production costs

International Nuclear Information System (INIS)

Kimming, M.; Sundberg, C.; Nordberg, Å.; Hansson, P.-A.

2015-01-01

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

Image fusion using single photon emission computed tomography - computed tomography (SPECT - CT) associates functional and morphological images. This study evaluates the added value of SPECT- CT, obtained with a hybrid SPECT- CT gamma camera, on anatomic localization and diagnostic impact in assessment of endocrine tumours and pheochromocytomas. Method: Six months prospective study was undertaken including 33 consecutive exams encompassing 20 Somatostatin Receptor Scintigraphies (S.R.S.) and 13 123 I-meta-iodo-benzyl-guanidine (Mibg) scans. Two experienced nuclear medicine physicians independently analysed independently planar and SPECT images in a first time, then, SPECT- CT fused images in a second time. They evaluated two parameters: SPECT- CT impact on anatomic localization (L.A.) and its diagnostic impact (I.D.). Each parameter was scored according three levels of evaluation. Results: An added value of SPECT- CT images was evidenced in 55% of cases on the anatomic localization and in 41% of the patients on the diagnostic impact. Therefore, a more important benefit was noted when SPECT was positive (L.A.: 90%; I.D.: 70%) than when it was negative (L.A.: 15%; I.D.: 8%). Furthermore, the added value proved higher for the S;R.S. compared to Mibg scans. Conclusion: SPECT- CT fusion images obtained by a hybrid system is more relevant to determine anatomic localization and more accurate than SPECT alone, particularly in the assessment of endocrine tumours. The added value of SPECT- CT seems to be lower for Mibg scans in the assessment of pheochromocytomas. (authors)

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.

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.

Wood-based bioenergy value chain in mountain urban districts: An integrated environmental accounting framework

Nikodinoska, Natasha; Buonocore, Elvira; Paletto, Alessandro; Franzese, Pier Paolo

2017-01-01

Highlights: • The Sarentino bioenergy value chain (North Italy) was investigated. • A multi-method environmental accounting framework was implemented. • Environmental costs and impacts of a forest bioenergy chain were assessed. • Indicators show a good environmental performance and sustainability. • Linking wood industry and energy production could lower the environmental burden. - Abstract: Using wood biomass for bioenergy production in mountain urban settlements can represent a win–win strategy when it combines a continuous energy provision to households with a sustainable management of local forests, also boosting rural development and stakeholders’ cooperation. In this study, we implemented a multi-method environmental accounting framework aimed at investigating environmental costs and impacts of a bioenergy value chain located in Sarentino Valley (North Italy). This assessment framework encompasses material, energy, and emergy demands as well as main emissions generated at each step of the chain: (1) forestry, (2) logistics, and (3) conversion. The resulting global to local ratios of abiotic material calculated for forestry, logistics, and conversion subsystems show that the global (direct and indirect) consumption of abiotic matter was respectively 3.6, 3.2, and 7.6 times higher than the direct material demand. The Energy Return on Energy Investment (EROI) of wood biomass and wood chips production (37.1 and 22.4) shows a high energy performance of these processes, while the EROI of heat generation (11.35) reflects a higher support of human-driven inputs. The emergy renewable fraction, ranging from 77% to 37% across the value chain, shows a high use of local renewable resources in the bioenergy value chain. The total CO_2 emissions of the bioenergy value chain (4088 t CO_2 yr"−"1) represent only 7.1% of the CO_2 sequestration potential of the Sarentino Valley forest ecosystem, highlighting the capability of the local forests to offset the CO_2

The impact of calcium assay change on a local adjusted calcium equation.

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.

Evaluating the impact of agritourism on local development in small islands

Directory of Open Access Journals (Sweden)

Sofia Karampela

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.

Impacts of East Asian Sulfate Aerosols on Local and Remote Climate

Science.gov (United States)

Bartlett, R. E.; Bollasina, M. A.

2017-12-01

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

Reintroduction of locally extinct vertebrates impacts arid soil fungal communities.

Science.gov (United States)

Clarke, Laurence J; Weyrich, Laura S; Cooper, Alan

2015-06-01

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.

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

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

Local search algorithms for combinatorial search problems frequently encounter a sequence of states in which it is impossible to improve the value of the objective function; moves through these regions, called {\\em plateau moves), dominate the time spent in local search. We analyze and characterize {\\em plateaus) for three different classes of randomly generated Boolean Satisfiability problems. We identify several interesting features of plateaus that impact the performance of local search algorithms. We show that local minima tend to be small but occasionally may be very large. We also show that local minima can be escaped without unsatisfying a large number of clauses, but that systematically searching for an escape route may be computationally expensive if the local minimum is large. We show that plateaus with exits, called benches, tend to be much larger than minima, and that some benches have very few exit states which local search can use to escape. We show that the solutions (i.e. global minima) of randomly generated problem instances form clusters, which behave similarly to local minima. We revisit several enhancements of local search algorithms and explain their performance in light of our results. Finally we discuss strategies for creating the next generation of local search algorithms.

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.

Christian Göbel

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.

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)

Imbert, P.

2011-01-01

Following the integrated energy planning paradigm in the 90's and the recent renewal of decentralized energy planning interests, Demand Side Management (DSM) actions are expected to take a significant role on energy planning activities in the future. Indeed the DSM actions represent a relevant option to achieve environmental and energy commitments or to alleviate some specific problems of electricity supply. DSM actions at the local scale at least in the French context is observed today. There is a need for appropriate methods and tools to assess the impacts of such MDE programs at local level. The local scale involves taking into account the specificities of the territories (physical, social, geographical, economical, institutional, etc.) The objective of this thesis is to improve the spatial resolution of input variables for the use in DSM action simulation tools. Based on a case study in France (PREMIO project: smart architecture for load management applied to a district) and an existing simulation tool we will study the impacts of this local experience to several municipalities.

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.

The Impact of State Preemption of Local Smoking Restrictions on Public Health Protections and Changes in Social Norms

Directory of Open Access Journals (Sweden)

Paul D. Mowery

2012-01-01

Full Text Available Introduction. Preemption is a legislative or judicial arrangement in which a higher level of government precludes lower levels of government from exercising authority over a topic. In the area of smoke-free policy, preemption typically takes the form of a state law that prevents communities from adopting local smoking restrictions. Background. A broad consensus exists among tobacco control practitioners that preemption adversely impacts tobacco control efforts. This paper examines the effect of state provisions preempting local smoking restrictions in enclosed public places and workplaces. Methods. Multiple data sources were used to assess the impact of state preemptive laws on the proportion of indoor workers covered by smoke-free workplace policies and public support for smoke-free policies. We controlled for potential confounding variables. Results. State preemptive laws were associated with fewer local ordinances restricting smoking, a reduced level of worker protection from secondhand smoke, and reduced support for smoke-free policies among current smokers. Discussion. State preemptive laws have several effects that could impede progress in secondhand smoke protections and broader tobacco control efforts. Conclusion. Practitioners and advocates working on other public health issues should familiarize themselves with the benefits of local policy making and the potential impact of preemption.

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

Directory of Open Access Journals (Sweden)

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.

The financial crisis reduced the value of equities in state and local defined benefit pensions and hurt the funding status of these plans. The impact will become evident only over time, however, because actuaries in the public sector tend to smooth both gains and losses, typically over a five–year period. The first year for which the crisis will have a meaningful impact on reported funding status is fiscal 2009, since in most cases the fiscal 2008 books were closed before the market collapsed...

In pursuit of the heritage and place synergy: the environmental impact of Panemunė Castle as a heritage property and entirety of values. A study

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.

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.

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...

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.

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.

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

KAUST Repository

Brammer, Grant

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.

Smart Control of Air Climatization System in Function on the Values of Mean Local Radiant Temperature

Giuseppe Cannistraro

2015-08-01

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

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

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 2 for <1 yr; 1.74 and 1.90 Gy cm 2 for 1 to <5 yr; 2.83 and 3.22 Gy cm 2 for 5 to <10 yr; and 7.34 and 8.68 Gy cm 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 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 may be large differences

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

Clements, Tom; Milner-Gulland, E J

2015-02-01

The potential impacts of payments for environmental services (PES) and protected areas (PAs) on environmental outcomes and local livelihoods in developing countries are contentious and have been widely debated. The available evidence is sparse, with few rigorous evaluations of the environmental and social impacts of PAs and particularly of PES. We measured the impacts on forests and human well-being of three different PES programs instituted within two PAs in northern Cambodia, using a panel of intervention villages and matched controls. Both PES and PAs delivered additional environmental outcomes relative to the counterfactual: reducing deforestation rates significantly relative to controls. PAs increased security of access to land and forest resources for local households, benefiting forest resource users but restricting households' ability to expand and diversify their agriculture. The impacts of PES on household well-being were related to the magnitude of the payments provided. The two higher paying market-linked PES programs had significant positive impacts, whereas a lower paying program that targeted biodiversity protection had no detectable effect on livelihoods, despite its positive environmental outcomes. Households that signed up for the higher paying PES programs, however, typically needed more capital assets; hence, they were less poor and more food secure than other villagers. Therefore, whereas the impacts of PAs on household well-being were limited overall and varied between livelihood strategies, the PES programs had significant positive impacts on livelihoods for those that could afford to participate. Our results are consistent with theories that PES, when designed appropriately, can be a powerful new tool for delivering conservation goals whilst benefiting local people. © 2014 The Authors.

18 F-fluorodeoxyglucose (FDG) positron emission tomography (PET) image-derived parameters, such as standardized uptake value (SUV), functional tumour length (TL) and tumour volume (TV) or total lesion glycolysis (TLG), may be useful for determining prognosis in patients with oesophageal carcinoma. The objectives of this work were to investigate the prognostic value of these indices in oesophageal cancer patients undergoing combined chemoradiotherapy treatment and the impact of TV delineation strategies. A total of 45 patients were retrospectively analysed. Tumours were delineated on pretreatment 18 F-FDG scans using adaptive threshold and automatic (fuzzy locally adaptive Bayesian, FLAB) methodologies. The maximum standardized uptake value (SUV max ), SUV peak , SUV mean , TL, TV and TLG were computed. The prognostic value of each parameter for overall survival was investigated using Kaplan-Meier and Cox regression models for univariate and multivariate analyses, respectively. Large differences were observed between methodologies (from -140 to +50% for TV). SUV measurements were not significant prognostic factors for overall survival, whereas TV, TL and TLG were, irrespective of the segmentation strategy. After multivariate analysis including standard tumour staging, only TV (p < 0.002) and TL (p = 0.042) determined using FLAB were independent prognostic factors. Whereas no SUV measurement was a significant prognostic factor, TV, TL and TLG were significant prognostic factors for overall survival, irrespective of the delineation methodology. Only functional TV and TL derived using FLAB were independent prognostic factors, highlighting the need for accurate and robust PET tumour delineation tools for oncology applications. (orig.)

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.

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

Directory of Open Access Journals (Sweden)

Jianbin Fang

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 impact of social media followers on corporate value: An investigation of Australian 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 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.

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.

2018-01-01

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.

2015-01-01

This article statistically isolates the impacts of city-level permitting and other local regulatory processes on residential PV prices in the United States. We combine data from two “scoring” mechanisms that independently capture local regulatory process efficiency with the largest dataset of installed PV prices in the United States. We find that variations in local permitting procedures can lead to differences in average residential PV prices of approximately $0.18/W between the jurisdictions with the least-favorable and most-favorable permitting procedures. Between jurisdictions with scores across the middle 90% of the range (i.e., 5th percentile to 95th percentile), the difference is $0.14/W, equivalent to a $700 (2.2%) difference in system costs for a typical 5-kW residential PV installation. When considering variations not only in permitting practices, but also in other local regulatory procedures, price differences grow to $0.64–$0.93/W between the least-favorable and most-favorable jurisdictions. Between jurisdictions with scores across the middle 90% of the range, the difference is equivalent to a price impact of at least $2500 (8%) for a typical 5-kW residential PV installation. These results highlight the magnitude of cost reduction that might be expected from streamlining local regulatory regimes. - Highlights: • We show local regulatory processes meaningfully affect U.S. residential PV prices. • We use regression analysis and two mechanisms for “scoring” regulatory efficiency. • Local permitting procedure variations can produce PV price differences of $0.18/W. • Broader regulatory variations can produce PV price differences of $0.64–$0.93/W. • The results suggest the cost-reduction potential of streamlining local regulations

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

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

Can Cross-Listing Mitigate the Impact of an Information Security Breach Announcement on a Firm's Values?

Science.gov (United States)

Chen, Yong; Dong, Feng; Chen, Hong; Xu, Li

2016-08-01

The increase in globalization in the markets has driven firms to adopt online technologies and to cross-list their stocks. Recent studies have consistently found that the announcements of information security breaches (ISBs) are negatively associated with the market values of the announcing firms during the days surrounding the breach announcements. Given the improvement in firms’ information environments and the better protection for investors generated by cross-listing, does cross-listing help firms to reduce the negative impacts caused by their announcements of ISBs? This paper conducts an event study of 120 publicly traded firms (among which 25 cross-list and 95 do not), in order to explore the answer. The results indicate that the impact of ISB announcements on a firm's stock prices shows no difference between cross-listing firms and non-cross-listing firms. Cross-listing does not mitigate the impact of ISBs announcement on a firm's market value.

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

Science.gov (United States)

Chipman, A; Morrison, E

2013-04-23

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

Quantifying Economic Value of Coastal Ecosystem Services: A Review

2018-01-01

Full Text Available The complexity of quantifying ecosystem services in monetary terms has long been a challenging issue for economists and ecologists. Many case specific valuation studies have been carried out in various parts of the World. Yet, a coherent review on the valuation of coastal ecosystem services (CES, which systematically describes fundamental concepts, analyzes reported applications, and addresses the issue of climate change (CC impacts on the monetary value of CES is still lacking. Here, we take a step towards addressing this knowledge gap by pursuing a coherent review that aims to provide policy makers and researchers in multidisciplinary teams with a summary of the state-of-the-art and a guideline on the process of economic valuation of CES and potential changes in these values due to CC impacts. The article highlights the main concepts of CES valuation studies and offers a systematic analysis of the best practices by analyzing two global scale and 30 selected local and regional case studies, in which different CES have been valued. Our analysis shows that coral reefs and mangroves are among the most frequently valued ecosystems, while sea-grass beds are the least considered ones. Currently, tourism and recreation services as well as storm protection are two of the most considered services representing higher estimated value than other CES. In terms of the valuation techniques used, avoided damage, replacement and substitute cost method as well as stated preference method are among the most commonly used valuation techniques. Following the above analysis, we propose a methodological framework that provides step-wise guidance and better insight into the linkages between climate change impacts and the monetary value of CES. This highlights two main types of CC impacts on CES: one being the climate regulation services of coastal ecosystems, and the other being the monetary value of services, which is subject to substantial uncertainty. Finally, a

Full Text Available The leading local legislation act defining the spatial policy is the local development plan, the financing of which is the commune’s responsibility. The beneficiary of activities aimed at the transformation of the intended property use is its owner or its perpetual lessee – with lessees incurring the costs of adopting the local development plans through so-called zoning fees, the amount of which, often controversial, has become the source of numerous lawsuits. The presented problem of an outside-business and often radical change of land value corresponds to the market dilemmas in determining equivalent markets, and establishing price-setting factors and their impact on the value of real estate.

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.

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. 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. 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.

Assessing the Effects of Corporate Social Responsibility Standards in Global Value Chains

This paper considers the issue of corporate social responsibility (CSR) standard impact assessment in global value chains. CSR standards have proliferated in recent years, and several studies have attempted to assess their effects on local producers, workers, and the environment in developing...... countries. However, much less attention has been paid to the “dark side” of impact assessment – the ethical and political dilemmas that arise in the process of carrying out impact studies. This paper addresses this gap in literature, arguing that impact assessments of CSR standards may do more harm than...... good to the intended beneficiaries - developing country firms, farmers, workers, and communities - unless these ethical and political dilemmas are given serious consideration....

The Impact of Wind Power Projects on Residential Property Values in the United States: A Multi-Site Hedonic Analysis

Energy Technology Data Exchange (ETDEWEB)

With wind energy expanding rapidly in the U.S. and abroad, and with an increasing number of communities considering wind power development nearby, there is an urgent need to empirically investigate common community concerns about wind project development. The concern that property values will be adversely affected by wind energy facilities is commonly put forth by stakeholders. Although this concern is not unreasonable, given property value impacts that have been found near high voltage transmission lines and other electric generation facilities, the impacts of wind energy facilities on residential property values had not previously been investigated thoroughly. The present research collected data on almost 7,500 sales of singlefamily homes situated within 10 miles of 24 existing wind facilities in nine different U.S. states. The conclusions of the study are drawn from eight different hedonic pricing models, as well as both repeat sales and sales volume models. The various analyses are strongly consistent in that none of the models uncovers conclusive evidence of the existence of any widespread property value impacts that might be present in communities surrounding wind energy facilities. Specifically, neither the view of the wind facilities nor the distance of the home to those facilities is found to have any consistent, measurable, and statistically significant effect on home sales prices. Although the analysis cannot dismiss the possibility that individual homes or small numbers of homes have been or could be negatively impacted, it finds that if these impacts do exist, they are either too small and/or too infrequent to result in any widespread, statistically observable impact.

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

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.

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 Cities compete with each other in order to attract more tourists, investors, businesses or residents today. Therefore, more and more attention is paid to the brand building and promotion of the city to the users of local services. However, the perception of the city (brand can drastically vary among the users. The goal of this paper is to explore how the city of Trebinje is positioned in the minds of local services users. Determination of the status, image, and value of the city brand was carried out on the example of the city of Trebinje using Anholt-GfK Roper City Brands Index. Sample consisted of 505 respondents with four groups of local services users: residents, tourists, businessman, and investors. Key information is obtained from data processing after the survey, i.e. analysis of data obtained from questionnaires prepared for the purposes of this research.

Fitzpatrick, M. F.; Grigholm, B. O.

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

Impact of energy efficiency measures on the economic value of buildings

Popescu, Daniela; Bienert, Sven; Schuetzenhofer, Christian; Boazu, Rodica

2012-01-01

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.

Full Text Available The main objective of this paper is to examine the impact of FDI inflow on local entrepreneurship in Georgia. The secondary objective of the article is to determine what effects the business climate in the country has on the growth of local entrepreneurs. To verify the impact of foreign investments on domestic entrepreneurship, dynamics of active local enterprises in Georgia in the years 2005-2014 is used as a dependent variable. In regard with business climate, international business and credit rankings were selected to show how they are interrelated with foreign investments and how they affect domestic entrepreneurs. FDI has no significant effect on local entrepreneurship in Georgia, neither on their growth, nor on their fall, as Its share in the local economy is nominal. It is noteworthy, however, that inflow of foreign capital has positive impact on the country’s business climate, promoting its image and rising international recognition. The favorable business climate can help many local enterprises, especially SMEs, to benefit from liberal environment, financial and tax incentives, less regulation and bureaucracy. This paper intends to enrich relatively poor literature about FDI effects on Transcaucasian countries, providing a clear understanding to what extend the local entrepreneurship are under the influence of FDI and general business climate in the country.

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.

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.

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.

Jatropha cultivation in Malawi and Mozambique: impact on ecosystem services, local human well-being, and poverty alleviation

Full Text Available Jatropha-based biofuels have undergone a rapid boom-and-bust cycle in southern Africa. Despite strong initial support by governments, donors, and the private sector, there is a lack of empirical studies that compare the environmental and socioeconomic impacts of Jatropha's two dominant modes of production: large plantations and smallholder-based projects. We apply a rapid ecosystem services assessment approach to understand the impact of two Jatropha projects that are still operational despite widespread project collapse across southern Africa: a smallholder-based project (BERL, Malawi and a large plantation (Niqel, Mozambique. Our study focuses on changes in provisioning ecosystem services such as biofuel feedstock, food, and woodland products that can have important effects on human well-being locally. Qualitative information is provided for other regulating and cultural ecosystem services. Although at this stage no impact is tremendously positive or negative, both projects show some signs of viability and local poverty alleviation potential. However, their long-term sustainability is not guaranteed given low yields, uncertain markets, and some prevailing management practices.

Salinisation of freshwater has been identified as a serious environmental issue in Australia and around the world. Protective concentrations (trigger values) for salinity can be used to manage salinity impacts, though require locally relevant salinity tolerance information. 72-h acute salinity tolerance values were determined for 102 macroinvertebrates collected from 11 locations in four biologically distinct freshwater bio-regions in Northeast Australia and compared with sensitivities observed in Southeast Australia. The salinity tolerance of individual taxa was consistent across Northeast Australia and between Northeast and Southeast Australia. However, two distinct communities were identified in Northeast Australia using distributions of the acute tolerance values and a calculated index of salinity sensitivity. Salinity trigger values should therefore be representative of local or regionally relevant communities and may be adequately calculated using sensitivity values from throughout Eastern Australia. The results presented provide a basis for assessing salinity risk and determining trigger values for salinity in freshwater ecosystems at local and regional scales in Eastern Australia. - Salinity tolerance of macroinvertebrate communities vary in Eastern Australia hence water quality guidelines should be developed at a local or regional scale

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

Barrera-Ballesteros, Jorge K.

2016-09-01

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.

Integrating scientific and local knowledge to inform risk-based management approaches for climate adaptation

Directory of Open Access Journals (Sweden)

Nathan P. Kettle

2014-01-01

Full Text Available Risk-based management approaches to climate adaptation depend on the assessment of potential threats, and their causes, vulnerabilities, and impacts. The refinement of these approaches relies heavily on detailed local knowledge of places and priorities, such as infrastructure, governance structures, and socio-economic conditions, as well as scientific understanding of climate projections and trends. Developing processes that integrate local and scientific knowledge will enhance the value of risk-based management approaches, facilitate group learning and planning processes, and support the capacity of communities to prepare for change. This study uses the Vulnerability, Consequences, and Adaptation Planning Scenarios (VCAPS process, a form of analytic-deliberative dialogue, and the conceptual frameworks of hazard management and climate vulnerability, to integrate scientific and local knowledge. We worked with local government staff in an urbanized barrier island community (Sullivan’s Island, South Carolina to consider climate risks, impacts, and adaptation challenges associated with sea level rise and wastewater and stormwater management. The findings discuss how the process increases understanding of town officials’ views of risks and climate change impacts to barrier islands, the management actions being considered to address of the multiple impacts of concern, and the local tradeoffs and challenges in adaptation planning. We also comment on group learning and specific adaptation tasks, strategies, and needs identified.

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

Science.gov (United States)

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.

Structural damage induced by an accidental aircraft crash into a reinforced concrete structure includes local damage caused by the engine, the rigid portion of the aircraft, and the global elasto-plastic structural response caused by the entire aircraft. Local damage consists of spalling of concrete from the front face of the target together with missile penetration into the target, scabbing of concrete from the rear face of the target and perforation of the missile through the target. The engine is a soft missile that deforms during impact. An experimental research program has been planned and executed to establish a rational evaluation method of the local damage by the deformable engine missiles

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

Science.gov (United States)

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

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.

The value of environmental impact assessments

International Nuclear Information System (INIS)

Sohocki, D.D.

1996-01-01

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

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

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

Optimization of the fiber laser parameters for local high-temperature impact on metal

Science.gov (United States)

Yatsko, Dmitrii S.; Polonik, Marina V.; Dudko, Olga V.

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.

Achieving Value in Primary Care: The Primary Care Value Model.

Rollow, William; Cucchiara, Peter

2016-03-01

The patient-centered medical home (PCMH) model provides a compelling vision for primary care transformation, but studies of its impact have used insufficiently patient-centered metrics with inconsistent results. We propose a framework for defining patient-centered value and a new model for value-based primary care transformation: the primary care value model (PCVM). We advocate for use of patient-centered value when measuring the impact of primary care transformation, recognition, and performance-based payment; for financial support and research and development to better define primary care value-creating activities and their implementation; and for use of the model to support primary care organizations in transformation. © 2016 Annals of Family Medicine, Inc.

Local and Regional Impacts of Pollution on Coral Reefs along the Thousand Islands North of the Megacity Jakarta, Indonesia

2015-01-01

Worldwide, coral reefs are challenged by multiple stressors due to growing urbanization, industrialization and coastal development. Coral reefs along the Thousand Islands off Jakarta, one of the largest megacities worldwide, have degraded dramatically over recent decades. The shift and decline in coral cover and composition has been extensively studied with a focus on large-scale gradients (i.e. regional drivers), however special focus on local drivers in shaping spatial community composition is still lacking. Here, the spatial impact of anthropogenic stressors on local and regional scales on coral reefs north of Jakarta was investigated. Results indicate that the direct impact of Jakarta is mainly restricted to inshore reefs, separating reefs in Jakarta Bay from reefs along the Thousand Islands further north. A spatial patchwork of differentially degraded reefs is present along the islands as a result of localized anthropogenic effects rather than regional gradients. Pollution is the main anthropogenic stressor, with over 80% of variation in benthic community composition driven by sedimentation rate, NO2, PO4 and Chlorophyll a. Thus, the spatial structure of reefs is directly related to intense anthropogenic pressure from local as well as regional sources. Therefore, improved spatial management that accounts for both local and regional stressors is needed for effective marine conservation. PMID:26378910

2017-12-01

Full Text Available To remain competitive within the current, uncertain business scenario, it is vital for firms to develop capabilities that lead them to adapt and offer quick responses to market changes. 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.

Engineering, global health, and inclusive innovation: focus on partnership, system strengthening, and local impact for SDGs.

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.

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

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

CERN Document Server

Valent, Tullio

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. The clever use of the inverse function theorem in finite elasticity made by STOPPELLI [1954, 1957a, 1957b]...

In Brief: Impacts of wind energy assessed

Zielinski, Sarah

2007-05-01

By 2020, greater use of wind energy could reduce carbon dioxide emissions by the U.S. energy sector by about 4.5%. However, greater effort is needed to address potentially negative impacts of this growing energy source, according to a new report from a committee of the U.S. National Research Council. Potential impacts of wind energy projects include deaths of birds and bats, reduced value of property located near a turbine, and habitat loss and fragmentation. However, because these are generally local projects, there is little information available to determine the cumulative effects of wind turbines over a whole region. The report makes several recommendations on how to improve regulation at the local, state, and federal levels. The report also sets out a guide for evaluating wind-energy projects, which includes questions about potential environmental, economic, cultural, and aesthetic impacts. The report, ``Environmental Impacts of Wind-Energy Projects,'' is available at http://books.nap.edu/catalog.php?record_id=11935

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

Longitudinally Vibrating Elastic Rods with Locally and Non-Locally Reacting Viscous Dampers

Directory of Open Access Journals (Sweden)

2005-01-01

Full Text Available Eigencharacteristics of a longitudinally vibrating elastic rod with locally and non-locally reacting damping are analyzed. The rod is considered as a continuous system and complex eigenfrequencies are determined as solution of a characteristic equation. The variation of the damping ratios with respect to damper locations and damping coefficients for the first four eigenfrequencies are obtained. It is shown that at any mode of locally or non-locally damped elastic rod, the variation of damping ratio with damper location is linearly proportional to absolute value of the mode shape of undamped system. It is seen that the increasing damping coefficient does not always increase the damping ratio and there are optimal values for the damping ratio. Optimal values for external damping coefficients of viscous dampers and locations of the dampers are presented.

Impact of highway construction on land surface energy balance and local climate derived from LANDSAT satellite data.

Science.gov (United States)

Nedbal, Václav; Brom, Jakub

2018-08-15

Extensive construction of highways has a major impact on the landscape and its structure. They can also influence local climate and heat fluxes in the surrounding area. After the removal of vegetation due to highway construction, the amount of solar radiation energy used for plant evapotranspiration (latent heat flux) decreases, bringing about an increase in landscape surface temperature, changing the local climate and increasing surface run-off. In this study, we evaluated the impact of the D8 highway construction (Central Bohemia, Czech Republic) on the distribution of solar radiation energy into the various heat fluxes (latent, sensible and ground heat flux) and related surface functional parameters (surface temperature and surface wetness). The aim was to describe the severity of the impact and the distance from the actual highway in which it can be observed. LANDSAT multispectral satellite images and field meteorological measurements were used to calculate surface functional parameters and heat balance before and during the highway construction. Construction of a four-lane highway can influence the heat balance of the landscape surface as far as 90m in the perpendicular direction from the highway axis, i.e. up to 75m perpendicular from its edge. During a summer day, the decrease in evapotranspired water can reach up to 43.7m 3 per highway kilometre. This means a reduced cooling effect, expressed as the decrease in latent heat flux, by an average of 29.7MWh per day per highway kilometre and its surroundings. The loss of the cooling ability of the land surface by evaporation can lead to a rise in surface temperature by as much as 7°C. Thus, the results indicate the impact of extensive line constructions on the local climate. Copyright © 2018 Elsevier B.V. All rights reserved.

Flood vulnerability, local perception and gender role judgment using multivariate analysis: A problem-based “participatory action to Future Skill Management” to cope with flood impacts

Full Text Available Flood impacts and social vulnerability are substantial threats for the sustainable development of the developing world. This study focuses on some particular points of flood impacts and the local concept towards existing management capacity. Additionally, significant focus was given to gender roles and how they may impact measures that aim towards reducing flood risks. Both qualitative and quantitative techniques were applied during the research, in order to understand the perception of the char-land communities on natural hazards, social crisis, resource accessibility, climatic uncertainty and the gender role to cope with flood consequences. Concurrently the questionnaire survey and focus group discussion (FGD was performed among the local people. This study revealed that majority of the people was directly threatened by the destructive consequences of flood hazards, which in turn, badly influenced the household economies, alongside its education, security and infrastructural prospects. Some decades ago, the application of indigenous techniques was deemed successful as the communities managed to effectively reduce the risk involved with potential floods. However, now the solution is no longer clear as it is disturbed by external climate components. Results showed the vulnerability of the local communities in terms of knowledge, resource access, communication system, proper information dissemination, health, and livelihood. The gender variability is believed to have significant value in terms of flood disaster risk reduction, household development, and family caring activities. Principal component analysis (PCA and cluster analysis (CA has clearly identified the gender role in the char-land community. The women's activities are profoundly focused in terms of the flood risk management, and the families generally do not properly appreciate the value of women and their role. However, the problem-based “Participatory Action to Future Skill

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...

Bringing the Consumer Back in—The Motives, Perceptions, and Values behind Consumers and Rural Tourists’ Decision to Buy Local and Localized Artisan Food—A Swedish Example

Paulina Rytkönen

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.

Climate change impacts on coral reefs: synergies with local effects, possibilities for acclimation, and management implications.

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

2007-09-01

Full Text Available Background: Introduction of health impact assessment (HIA as a national legal requirement for planned economic activity projects in 2002 and the further development of related procedures and methodological requirements has boosted the number of HIAs carried out both as an integrated part of environmental impact assessment (EIA procedures as well as an independent activity. Most of HIAs have been conduct for local projects. The HIA for the reconstruction of the southern section of the railroads in Klaip da National Seaport is one of the local HIAs in Lithuania carried out as an independent procedure. Methods: The HIA for the reconstruction of the southern section of the railroads in Klaipda National Seaport was carried out following the national legal procedure for the cases not foreseen in the Law on Environmental Impact Assessment of Planned Economic Activity and the national HIA methodological regulations. The HIA included a literature review, analysis of related technical documentation, data on existing and estimated air pollution and environmental noise levels and possible health consequences, analysis of local demographic and health statistics; interviews with the residents living in proximity of the planned activity, analysis of public complaints on existing activities at Klaip da National Seaport, site visit and round table discussions with the proponent of the planned activity, planning company and representatives of the public health authority. The standard or intermediate type of perspective HIA was applied. Results: The HIA report has pointed out noise, vibration, ambient air pollution, psychological factors as related to possible negative impact on health of residents living in the mostly exposed locations. Interviews with inhabitants living in proximity of the planned activity have shown that majority of them knew nothing about the reconstruction plans. Recommendations were provided in the report how to minimise

Nature of local benefits to communities impacted by sour gas development : Public safety and sour gas recommendation 79 : Final report

International Nuclear Information System (INIS)

2003-09-01

The Provincial Advisory Committee on Public Safety and Sour Gas of Alberta issued a report in December 2002, in which recommendations were made on how to improve the sour gas regulatory system and reduce the impacts of sour gas on public safety and health. Recommendation 79 of this report called for a study to determine the nature of local benefits such as property taxes and local business opportunities, to communities affected by sour gas development. The present document was prepared by a multi-stake holder committee consisting of representatives from municipal government, academia, industry associations, the provincial government, and the public. One of its objectives was to identify matters of importance to stake holders concerning the study. The committee examined three major areas: economic benefit, net financial benefit to municipalities, and impact of sour gas development on local residents. The results indicated that the province and municipalities in which sour gas activities take place benefit from these activities. All Albertans benefit somewhat, and those living in areas where the sour gas industry operates might benefit through employment or the net benefit accrued to municipal government. A detailed quantification of local benefits at the municipal level for individuals was provided in this document. A full accounting of costs or negative impacts that may affect some individuals was not provided. refs., 6 tabs

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...

The aim of our study was to investigate and evaluate the prognostic value of and correlations between preclinical and clinical factors such as the stage of the disease, blood Hb level before treatment, size of cervix and lymph nodes evaluated by CT, age, dose of irradiation and duration of radiotherapy related to overall survival, disease-free survival, local control and metastases-free survival in cervical cancer patients receiving radiotherapy alone. 162 patients with International Federation of Gynecology and Obstetrics (FIGO) stage IIA-IIIB cervical carcinoma treated with irradiation were analysed. Univariate and multivariate analyses using the Cox regression model were performed to determine statistical significance of some tumor-related factors. The Hb level before treatment showed significant influence on overall survival (p = 0.001), desease free survival (p = 0.040) and local control (p = 0.038). The lymph node status (>10 mm) assessed on CT had impact on overall survival (p = 0,030) and local control (p = 0,036). The dose at point A had impact on disease free survival (p = 0,028) and local control (p = 0,021) and the radiotherapy duration had showed significant influence on overall survival (p = 0,045), disease free survival (p = 0,006) and local control (p = 0,033). Anemia is a significant and independent prognostic factor of overall survival, disease-free survival and local control in cervical cancer patients treated with irradiation. The size of lymph nodes in CT is an independent prognostic factor for overall survival and local control in cervical cancer patients. The size of cervix uteri evaluated by CT has no prognostic significance in cervical cancer patients treated with radiotherapy. The prognostic value of FIGO stage of cervical cancer is influenced by other factors, analyzed in this study and is not an independent prognostic factor

Target tracking is an important application of wireless sensor networks. The networks' ability to locate and track an object is directed linked to the nodes' ability to locate themselves. Consequently, localization systems are essential for target tracking applications. In addition, sensor networks are often deployed in remote or hostile environments. Therefore, density control algorithms are used to increase network lifetime while maintaining its sensing capabilities. In this work, we analyze the impact of localization algorithms (RPE and DPE) and density control algorithms (GAF, A3 and OGDC) on target tracking applications. We adapt the density control algorithms to address the k-coverage problem. In addition, we analyze the impact of network density, residual integration with density control, and k-coverage on both target tracking accuracy and network lifetime. Our results show that DPE is a better choice for target tracking applications than RPE. Moreover, among the evaluated density control algorithms, OGDC is the best option among the three. Although the choice of the density control algorithm has little impact on the tracking precision, OGDC outperforms GAF and A3 in terms of tracking time. PMID:22969329

The economic impact of shale gas development on state and local economies: benefits, costs, and uncertainties.

Barth, Jannette M

2013-01-01

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

Assessment of Global Emissions, Local Emissions and Immissions of Different Heating Systems

Directory of Open Access Journals (Sweden)

Georg Erdmann

2009-08-01

Full Text Available This paper assesses and compares existing and new technologies for space heating in Germany (e.g., heat pumps, and solar thermal and wood pellet systems in terms of their environmental impacts. The various technologies were analyzed within the context of the new German legislation. The assessment was carried out on three levels: 1. Global emissions: a life cycle assessment was carried out in order to find the global environmental footprint of the various technologies; 2. Local emissions: the effects of local emissions on human health were analyzed; and 3. Immissions: the immissions were evaluated for the various technologies using a dispersion calculation. A special feature of this study is the substitution of frequently used database emission values by values obtained from field studies and our own measurements. The results show large differences between the different technologies: while electric heat pumps performed quite well in most categories, wood pellet systems performed the best with respect to climate change. The latter, however, are associated with high impacts in other environmental impact categories and on a local scale. The promotion of some technologies (especially systems based on fuel oil, a mixture of fuel oil and rapeseed oil, or a mixture of natural gas and biomethane by the newly introduced German legislation is doubtful. In terms of the immissions of wood pellet systems, it can be concluded that, even for extremely unfavorable meteorological conditions, the regulatory limits are not exceeded and the heating systems have a negligible influence on the total PM load in the ambient air.

Peslen, C. A.

1979-01-01

The impact of 5 minute interval SMS-2 visible digital image data in analyzing severe local storms is examined using wind vectors derived from cloud tracking on time lapsed sequence of geosynchronous satellite images. The cloud tracking areas are located in the Central Plains, where on 6 May 1975, hail-producing thunderstorms occurred ahead of a well defined dry line. The results demonstrate that satellite-derived wind vectors and their associated divergence fields complement conventional meteorological analyses in describing the conditions preceding severe local storm development.

2009-01-01

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.

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.

Decreasing traffic speeds increases the amount of time drivers have to react to road hazards, potentially averting collisions, and makes crashes that do happen less severe. Boston's regional planning agency, the Metropolitan Area Planning Council (MAPC), in partnership with the Massachusetts Department of Public Health (MDPH), conducted a Health Impact Assessment (HIA) that examined the potential health impacts of a proposed bill in the state legislature to lower the default speed limits on local roads from 30 miles per hour (mph) to 25 mph. The aim was to reduce vehicle speeds on local roads to a limit that is safer for pedestrians, cyclists, and children. The passage of this proposed legislation could have had far-reaching and potentially important public health impacts. Lower default speed limits may prevent around 18 fatalities and 1200 serious injuries to motorists, cyclists and pedestrians each year, as well as promote active transportation by making local roads feel more hospitable to cyclists and pedestrians. While a lower speed limit would increase congestion and slightly worsen air quality, the benefits outweigh the costs from both a health and economic perspective and would save the state approximately $62 million annually from prevented fatalities and injuries.

Sustainable Radioactive Waste Management: Reflections on Building a Durable Relationship Between a Facility and the Local Community by Adding Value to Waste Management Projects

International Nuclear Information System (INIS)

Van Hove, Erik

2009-01-01

The appropriate model for radioactive waste management projects is clearly the insertion in the local economy. The author of this paper states that RWM initiatives need a committed and knowledgeable host community over a very long period. This can only be achieved if RWM projects are firmly localised and tied in with the daily life of the host community: RWM projects should go local and bring value to the community in multiple ways. As global economy rules very much dominate the present thinking and norm setting, a durable RWM initiative does not come about spontaneously, explicit value adding measures are required: attention to design (go outside the circle of utilitarian engineering and bring in some creativity and imagination), go for multi-functionality (visitor center, sports facility, etc.), distinctiveness (remarkable architecture, beautiful landscaping, unusual features in the engineering...), meaningful service to society. There are also some preconditions such as sustainable integration of projects in the local community (develop projects in local partnerships) and avoiding the trap of safety-through-adversarial-security

Wind energy development and perceived real estate values in Ontario, Canada

Directory of Open Access Journals (Sweden)

Chad Walker

2014-11-01

Full Text Available This paper focuses on public concerns about real estate value loss in communities in the vicinity of wind turbines. There are some conflicting results in recent academic and non-academic literatures on the issue of property values in general—yet little has been studied about how residents near turbines view the value of their own properties. Using both face-to-face interviews (n = 26 and community survey results (n = 152 from two adjacent communities, this exploratory mixed-method study contextualizes perceived property value loss. Interview results suggest a potential connection between perceived property value loss and actual property value loss, whereby assumed property degradation from turbines seem to lower both asking and selling prices. This idea is reinforced by regression results which suggest that felt property value loss is predicted by health concerns, visual annoyances and community-based variables. Overall, the findings point to the need for greater attention to micro-level local, and interconnected impacts of wind energy development.

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

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

Johnson, H. J.; Montoya, E. J.

1973-01-01

The flow field at the left inlet spike tip of a YF-12A airplane was examined using at 26 deg included angle conical flow sensor to obtain measurements at free-stream Mach numbers from 1.6 to 3.0. Local flow angularity, Mach number, impact pressure, and mass flow were determined and compared with free-stream values. Local flow changes occurred at the same time as free-stream changes. The local flow usually approached the spike centerline from the upper outboard side because of spike cant and toe-in. Free-stream Mach number influenced the local flow angularity; as Mach number increased above 2.2, local angle of attack increased and local sideslip angle decreased. Local Mach number was generally 3 percent less than free-stream Mach number. Impact-pressure ratio and mass flow ratio increased as free-stream Mach number increased above 2.2, indicating a beneficial forebody compression effect. No degradation of the spike tip instrumentation was observed after more than 40 flights in the high-speed thermal environment encountered by the airplane. The sensor is rugged, simple, and sensitive to small flow changes. It can provide accurate imputs necessary to control an inlet.

Promotion of dietary diversity using locally available nutritious foods is an effective approach in low-income areas to improve the quality of young children's diet and, hence, their growth and development. To identify the nutritional values of locally acceptable, feasible, affordable, and sustainable foods and develop a number of recipes that could be used to complement effectively nutrient intakes provided through breastfeeding to children 6 to 23 months of age in Bandiagara, Mali. Structured questionnaires were used to obtain lists of all locally available foods during village assembly meetings and identify the food basket of households and child feeding practices during interviews with mothers and fathers. The nutritional values of the foods were estimated, and the Malian food composition table was used to identify the combinations that would result in the most nutritious recipes. Breastfeeding was widely practiced, but the rate of exclusive breastfeeding during the first 6 months of life was extremely low (7%). The practice of early introduction of water and complementary foods was a problem. Forty recipes for improved dishes, including puddings, drinks and juices, purees, salads, and soups, were proposed. The nutritional values of the 10 most nutritious of these recipes, the types and quantities of the ingredients, and the method of preparation of each recipe are described. Locally produced indigenous foods in rural Mali were used to develop energy- and nutrient-dense complementary foods for children. Further research is needed to test the short- and long-term effects of consuming these dishes on the nutritional status of children 6 to 23 months of age in Mali.

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.

Full Text Available OBJECTIVES: To analyze the behavior of the prostate specific antigen velocity (PSAV in localized prostate adenocarcinoma. MATERIALS AND METHODS: We conducted a retrospective study of 500 men who had localized prostate adenocarcinoma, who underwent radical retropubic prostatectomy between January 1986 and December 1999. The PSAV was calculated for each patient and subsequently, the values were correlated with 5 groups: age, initial PSA value, clinical stage, tumor volume and Gleason score. RESULTS: The behavior of PSAV presented statistic significance with an increment between 1.3 ng/mL and 9.6 ng/mL, ranging from 38.6% and 59.8% when compared with the initial PSA value (p < 0.0001, clinical stage (p = 0.0002, tumor volume (p < 0.0001 and Gleason score (p = 0.0009. CONCLUSION: PSAV up to 2.5 ng/mL/year is associated with factors of good prognosis, such as initial PSA below 10 mg/mL, clinical stage T1, tumor volume below 20% and Gleason score lower than 7.

Sieglinde Kindl da Cunha

2005-07-01

Full Text Available This article proposes a model to measure tourism cluster impact on local development with a view to assessing tourism cluster interaction, competitiveness and sustainability impacts on the economy, society and the environment. The theoretical basis for this model is founded on cluster concept and typology adapting and integrating the systemic competitiveness and sustainability concepts within economic, social, cultural, environmental and political dimensions. The proposed model shows a holistic, multidisciplinary and multi-sector view of local development brought back through a systemic approach to the concepts of competitiveness, social equity and sustainability. Its results make possible strategic guidance to agents responsible for public sector tourism policies, as well as the strategies for competitiveness, competition, cooperation and sustainability in private companies and institutions.

Full Text Available Local ecosystem services have been significantly affected by land cover changes associated with rapid urbanization in China. Based on the 2000 and 2010 land cover data products with 30-m resolution, we examined the similarities and differences in the impacts of land cover change on ecosystem service values (ESV at three coastal urban agglomerations in China between 2000 and 2010 (Liaodong Peninsula (LP, Jing-Jin-Ji (JJJ and Shandong Peninsula (SP. A rapid evaluation method developed by Xie et al. (2008 was used to derive an ecosystem service value coefficient. The most significant change was an increase in artificial surfaces, due to urban expansion, which mainly occurred on cultivated land. The greatest loss in total ESV (2273 million Chinese Yuan occurred in SP, due to the large decrease in wetland areas, because this service has the highest estimated coefficient. The second greatest loss in ESV (893 million Yuan occurred in JJJ, due to the urban expansion of major cities. In contrast, ESV increased (72 million Yuan in LP. This study demonstrates that urban expansion does not necessarily lead to a net decline in ESV. In conclusion, land use and land cover policymaking should consider the sustainability of ecosystem services in relation to economic growth.

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

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?

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.

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.

In England and Wales planning regulations require local governments to treat waste near its source. This policy principle alongside regional self-sufficiency and the logistical advantages of minimising distances for waste treatment mean that energy from waste incinerators have been built close to, or even within urban conurbations. There is a clear policy and research need to balance the benefits of energy production from waste incinerators against the negative externalities experienced by local residents. However, the monetary costs of nuisance emissions from incinerators are not immediately apparent. This study uses the Hedonic Pricing Method to estimate the monetary value of impacts associated with three incinerators in England. Once operational, the impact of the incinerators on local house prices ranged from approximately 0.4% to 1.3% of the mean house price for the respective areas. Each of the incinerators studied had been sited on previously industrialised land to minimise overall impact. To an extent this was achieved and results support the effectiveness of spatial planning strategies to reduce the impact on residents. However, negative impacts occurred in areas further afield from the incinerator, suggesting that more can be done to minimise the impacts of incinerators. The results also suggest that in some case the incinerator increased the value of houses within a specified distance of incinerators under specific circumstances, which requires further investigation.

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

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.

Local and global recoding methods for anonymizing set-valued data

KAUST Repository

Terrovitis, Manolis

2010-06-10

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.

Local control stations

1993-01-01

This paper describes research concerning the effects of human engineering design at local control stations (i.e., operator interfaces located outside the control room) on human performance and plant safety. The research considered both multifunction panels (e.g. remote shutdown panels) as well as single-function interfaces (e.g., valves, breakers, gauges, etc.). Changes in performance shaping factors associated with variations in human engineering at LCSs were estimated based on expert opinion. By means of a scaling procedure, these estimates were used to modify the human error probabilities in a PRA model, which was then employed to generate estimates of plant risk and scoping-level value/impact ratios for various human engineering upgrades. Recent documentation of human engineering deficiencies at single-function LCSs was also reviewed, and an assessment of the current status of LCSs with respect to human engineering was conducted

Framing Climate Change to Account for Values

Science.gov (United States)

Hassol, S. J.

2011-12-01

Belief, trust and values are important but generally overlooked in efforts to communicate climate change. Because climate change has often been framed too narrowly as an environmental issue, it has failed to engage segments of the public for whom environmentalism is not an important value. Worse, for some of these people, environmentalism and the policies that accompany it may be seen as a threat to their core values, such as the importance of personal freedoms and the free market. Climate science educators can improve this situation by more appropriately framing climate change as an issue affecting the economy and our most basic human needs: food, water, shelter, security, health, jobs, and the safety of our families. Further, because people trust and listen to those with whom they share cultural values, climate change educators can stress the kinds of values their audiences share. They can also enlist the support of opinion leaders known for holding these values. In addition, incorporating messages about solutions to climate change and their many benefits to economic prosperity, human health, and other values is an important component of meeting this challenge. We must also recognize that local impacts are of greater concern to most people than changes that feel distant in place and time. Different audiences have different concerns, and effective educators will learn what their audiences care about and tailor their messages accordingly.

Local court reforms and ‘global’ law

Directory of Open Access Journals (Sweden)

Richard Mohr

2007-06-01

Full Text Available This study considers court reform programmes sponsored by the IMF and World Bank in Indonesia and Venezuela. It aims to broaden the frame of reference of ‘globalisation’ in law beyond the two traditional sites of human rights and trade. Drawing on a tradition of legal pluralism, it investigates the various sources of ‘global’ or universalising pressures on the law. The sources and impacts of these efforts may derive from and benefit or disadvantage specific groups in various locations. They will also promote or inhibit particular political, social or economic projects. The study concludes that various constituencies and impulses to reform refer to different versions of the ‘universal’ for their conception of right and legitimacy. These are neither inherently local nor unambiguously global. Local religious or egalitarian movements may refer to universal religious or political values just as interests in fair commercial dealing can call on international legal norms. In contrast to the local sites where law is performed, these universal sites exist in a multitude of indigenous, religious, political and legal imagined communities, each of which may be invoked in attempts to reform local practice.

Engineering, global health, and inclusive innovation: focus on partnership, system strengthening, and local impact for SDGs

Full Text Available 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.

Contrast-enhanced dynamic MR mammography can provide important additional diagnostic information when performed for certain indications. When suspicious lesions are identified on MR mammography and cannot be reproduced using other imaging modalities, a decision must be made as to its management, i.e. further diagnostic work-up. One possibility is the short-term follow-up of such findings, resulting in higher costs and a possible delay in the start of treatment of a malignant lesion. An alternative to a follow-up is an MR-guide intervention. MR-compatible equipment has been developed for this purpose. This includes equipment specialized for percutaneous biopsy and preoperative localization. The following is an overview of the diagnostic value of MR-guided biopsy and preoperative localization including the relevant literature. (orig.)

This guide -- the JEDI Fast Pyrolysis Biorefinery Model User Reference Guide -- was developed to assist users in operating and understanding the JEDI Fast Pyrolysis Biorefinery Model. The guide provides information on the model's underlying methodology, as well as the parameters and data sources used to develop the cost data utilized in the model. This guide also provides basic instruction on model add-in features and a discussion of how the results should be interpreted. Based on project-specific inputs from the user, the JEDI Fast Pyrolysis Biorefinery Model estimates local (e.g., county- or state-level) job creation, earnings, and output from total economic activity for a given fast pyrolysis biorefinery. These estimates include the direct, indirect and induced economic impacts to the local economy associated with the construction and operation phases of biorefinery projects.Local revenue and supply chain impacts as well as induced impacts are estimated using economic multipliers derived from the IMPLAN software program. By determining the local economic impacts and job creation for a proposed biorefinery, the JEDI Fast Pyrolysis Biorefinery Model can be used to field questions about the added value biorefineries might bring to a local community.

Variation in sensitivity of large benthic Foraminifera to the combined effects of ocean warming and local impacts.

Large benthic foraminifera (LBF) are crucial marine calcifiers in coral reefs, and sensitive to environmental changes. Yet, many species successfully colonise a wide range of habitats including highly fluctuating environments. We tested the combined effects of ocean warming, local impacts and different light levels on populations of the common LBF Amphistegina lobifera collected along a cross-shelf gradient of temperature and nutrients fluctuations. We analysed survivorship, bleaching frequency, chlorophyll a content and fecundity. Elevated temperature and nitrate significantly reduced survivorship and fecundity of A. lobifera across populations studied. This pattern was exacerbated when combined with below optimum light levels. Inshore populations showed a consistent resistance to increased temperature and nitrate levels, but all populations studied were significantly affected by light reduction. These findings demonstrated the capacity of some populations of LBF to acclimate to local conditions; nonetheless improvements in local water quality can ultimately ameliorate effects of climate change in local LBF populations.

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.

Public Hearing or `Hearing Public'? An Evaluation of the Participation of Local Stakeholders in Environmental Impact Assessment of Ghana's Jubilee Oil Fields

This article investigates the involvement of local stakeholders in the environmental impact assessment (EIA) processes of Ghana's first off-shore oil fields (the Jubilee fields). Adopting key informants interviews and documentary reviews, the article argues that the public hearings and the other stakeholder engagement processes were cosmetic and rhetoric with the view to meeting legal requirements rather than a purposeful interest in eliciting inputs from local stakeholders. It further argues that the operators appear to lack the social legitimacy and social license that will make them acceptable in the project communities. A rigorous community engagement along with a commitment to actively involving local stakeholders in the corporate social responsibility (CSR) programmes of the partners may enhance the image of the partners and improve their social legitimacy. Local government agencies should be capacitated to actively engage project organisers; and government must mitigate the impact of the oil projects through well-structured social support programmes.

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.

Effects of hydropower operations on recreational use and nonuse values at Glen Canyon and Flaming Gorge Dams

Energy Technology Data Exchange (ETDEWEB)

Carlson, J.L.

1995-03-01

Increases in streamflows are generally positively related to the use values of angling and white-water boating, and constant flows tend to increase the use values more than fluctuating flows. In most instances, however, increases in streamflows beyond some threshold level cause the use values to decrease. Expenditures related to angling and white-water boating account for about $24 million of activity in the local economy around Glen Canyon Dam and $24.8 million in the local economy around flaming Gorge Dam. The range of operational scenarios being considered in the Western Area Power Administration`s Electric Power Marketing Environmental Impact Statement, when use rates are held constant, could change the combined use value of angling and white-water boating below Glen Canyon Dam, increasing it by as much as 50%, depending on prevailing hydrological conditions. Changes in the combined use value below Flaming Gorge Dam could range from a decrease of 9% to an increase of 26%. Nonuse values, such as existence and bequest values, could also make a significant contribution to the total value of each site included in this study; however, methodological and data limitations prevented estimating how each operational scenario could change nonuse values.

Children as ethnobotanists: methods and local impact of a participatory research project with children on wild plant gathering in the Grosses Walsertal Biosphere Reserve, Austria.

Ethically sound research in applied ethnobiology should benefit local communities by giving them full access to research processes and results. Participatory research may ensure such access, but there has been little discussion on methodological details of participatory approaches in ethnobiological research. This paper presents and discusses the research processes and methods developed in the course of a three-year research project on wild plant gathering, the involvement of children as co-researchers and the project's indications for local impact. Research was conducted in the Grosses Walsertal Biosphere Reserve, Austria, between 2008 and 2010 in four research phases. In phase 1, 36 freelist interviews with local people and participant observation was conducted. In phase 2 school workshops were held in 14 primary school classes and their 189 children interviewed 506 family members with structured questionnaires. In phase 3, 27 children and two researchers co-produced participatory videos. In phase 4 indications for the impact of the project were investigated with questionnaires from ten children and with participant observation. Children participated in various ways in the research process and the scientific output and local impact of the project was linked to the phases, degrees and methods of children's involvement. Children were increasingly involved in the project, from non-participation to decision-making. Scientific output was generated from participatory and non-participatory activities whereas local impact - on personal, familial, communal and institutional levels - was mainly generated through the participatory involvement of children as interviewers and as co-producers of videos. Creating scientific outputs from participatory video is little developed in ethnobiology, whereas bearing potential. As ethnobotanists and ethnobiologists, if we are truly concerned about the impact and benefits of our research processes and results to local communities, the

Seamounts often satisfy numerous uses and interests. Multiple uses can generate multiple benefits but also conflicts and impacts, calling, therefore, for integrated and sustainable management. To assist in developing comprehensive management strategies, policymakers recognise the need to include measures of socioeconomic analysis alongside ecological data so that practical compromises can be made. This study assessed the direct output impact (DOI) of the relevant marine activities operating at Condor seamount (Azores, central northeast Atlantic) as proxies of the direct use values provided by the resource system. Results demonstrated that Condor seamount supported a wide range of uses yielding distinct economic outputs. Demersal fisheries, scientific research and shark diving were the top-three activities generating the highest revenues, while tuna fisheries, whale watching and scuba-diving had marginal economic significance. Results also indicated that the economic importance of non-extractive uses of Condor is considerable, highlighting the importance of these uses as alternative income-generating opportunities for local communities. It is hoped that quantifying the direct use values provided by Condor seamount will contribute to the decision making process towards its long-term conservation and sustainable use.

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